When there is an alarm, operators can handle common faults according to the screen prompts, without additional maintenance costs.Â
It is not easy to clog. We optimize the machine according to common clogging reasons.
Carton deformation: The anti-bridging device adjusts the lifting force of the machine to prevent flattening thin cartons.
The tape floats up and sticks to the next carton: when cutting the tape, the pressure wheel of the anti-slip gap device firmly presses the tape end, preventing the tape from flying off and avoiding sticking to the next tape.
The machine body uses a thickened steel body, which is 30% heavier than a common machine and absorbs high-frequency vibrations. The sensors and synchronous drive belt make precise tape positioning without skew, achieving a neat appearance and firm packaging.Â
The maintenance of the machine is very simple.
Due to the high operation speed, we add easy lubrication design to the motor and bearing shaft, significantly reducing the maintenance frequency.Â
The core spare parts of the machine adopt a modular quick-release structure and it only takes a few minutes to replace.
The fault diagnosis system is intuitive and quickly locates and solves minor problems in production through the HMI screen. There is no need to wait for the master to fix or contact the supplier, minimizing downtime.
The servo motor driven case sealer has a buffer before starting, which prevents instant or toppling over due to inertia. The clamping force of the belt can be adjusted according to the material and load capacity of the carton, ensuring the clamping is stable and does not damage products or cartons.Â
We customize fragile protection solutions according to your product properties, helping you reduce return claims, especially suitable for food and beverages and cosmetics industry.
When delivery, we include a set of accessories for consumable parts. As the original manufacturer, we store a sufficient stock of spare parts. If you order the spare parts, we offer global express delivery to ensure your production line won’t be forced to stop for a long time due to the absence of a single part.
The entire machine fully complies with the CE safety standards. Key moving parts are installed with transparent protective covers and safety limit switches. Once the protective door is opened, the machine will automatically cut off the power supply. It also equips multiple prominent emergency stop buttons to ensure the machine can stop instantly in any emergency situation.
Conveyer BeltÂ
The high speed case sealer operates continuously and the belt will undergo temperature rising and wear. We use widened and high-friction synchronous belts, whose tooth profile meshes perfectly with the drive wheel, ensuring no slipping of carton during high-speed movement.Â
We add a heat-resistant formula to the belt material, which reduces 30% in temperature rise compared to ordinary belts and extends the service life by more than twice. This reduces belt replacement frequency by 50%, saving maintenance costs and downtime.Â
Lateral Guide RailÂ
Lateral guide rail automatically adjusts cartons to convey them in the center, preventing tape deviation from affecting brand image.Â
For cosmetics and pharmaceutical industries that require high sealing accuracy, we use high-precision lead screw mechanism to synchronously drive guide rails, controlling the pressure on two sides to be uniform. The inner lining of the adjustable guide rail uses low-friction and wear-resistant material, ensuring there is no scratches on the printed surface.
Top Cover Folding DeviceÂ
The mechanical linkage structure of the top cover folding device automatically folds the top flat of the carton flat. It does not need electronic control and folds the top cover through the carton’s own forward movement within 0.3 seconds. This achieves an extremely low failure rate and nearly zero maintenance cost.Â
Adhesive Tape Case Sealer Machine HeadÂ
The rubber head seat of the machine supports large-sized adhesive tape, reducing frequency of changing rolls and manual intervention. We use a high-hardness serrated blade to handle the toughness of the tape and cut tape within milliseconds. This achieves a smooth cut without burrs and prevents the carton from cracking during transportation.Â
The wipe-down rollers press the tape end tightly onto the back of the carton, ensuring the tail end adheres closely to the carton without lifting, enhancing the packaging image and the unboxing experience of consumers.
Kickboard DeviceÂ
The servo-controlled rear baffle kickboard device replaces the cylinder and can precisely calculate the timing and force for kicking out based on the carton length. Compared with cylinders, it increases 40% speed and decreases expensive air consumption, which is suitable for workshops without centralized gas supply or packaging lines that need to control noise.Â
All-metal connecting rods replace rubber seals, extending the lifespan of components by more than three times compared to cylinders.
Adjustment DeviceÂ
The adjustment device is closely related to the sealing accuracy. Our automatic high speed case sealer uses servo motor regulation. operators only need to input carton size through PLC and the machine automatically adjusts it with a repeat positioning accuracy as high as ±0.5mm, ensuring even small cartons can be precisely sealed.Â
Automatic Photoelectric Detection SystemÂ
The automatic photoelectric detection system accurately positions the carton, triggers the sealing device, and calculates the number of sealed cartons. It prevents jamming and missed sealing. The sensor shell uses IP67 dustproof and waterproof design, ensuring stable operation even in damp or dusty workshops, with a low failure rate.Â
How to Choose a Suitable High Speed Case Sealer?
Case Sealing RequirementsÂ
Different sealing products have different precautions during sealing. We customize sealing solutions according to the characteristics of your products, reducing product damage originally.Â
Fragile Products-Buffering StartupÂ
Beverage glass bottles and electronic products are fragile and easy to tip over due to inertia. We recommend buffer start of the S-curve, enabling the motor speed to smoothly transfer from 0 to the set value without instant impact. The clamping device adjusts pressure and applies low pressure to soft-packaged food, preventing damaging the product.
Heavy Products – High-friction Conveying BeltÂ
The weight of heavy products such as hardware and mechanical parts can reach 20-50kg. Sufficient friction is needed to prevent slippage and deviation during conveying. We recommend customizing high speed case sealers with high-friction belt and thickened machine body to withstand impacts from heavy cartons. This reduces the frequency of downtime to change the strap.Â
Cartons with Multiple Sizes- Automatically Adjustable Case SealerÂ
If your products have many specifications and are very different in sizes, we recommend automatic adjustable high speed case sealer. It automatically identifies carton sizes through the photoelectric detection system and adjusts height and width within 10 seconds.Â
For e-commerce involving mixed-line production, automatic adjustment case sealer saves 4-5 hours of production changeover time each day compared to manual adjustment, significantly improving the packaging efficiency.
Carton Shape – Customized Guide RailsÂ
If your carton is a standard slotted carton, you can directly choose a standard model high speed case sealer. If your cartons have irregular shapes and asymmetric structure, we recommend customized guide rails, whose guiding arcs are designed according to the actual outline of the carton. You only need to send us your carton sample and we will customize guide rails compatible with your cartons.Â
Production Scale Â
Choosing high speed case sealers according to your production scale prevents the machine from being too large to occupy too much production space or too small to handle large orders.
Average Daily Output > 10,000 Cases
For companies with large production scale, we recommend multi-head automatic high speed case sealers with a sealing speed of >40 cases/minute. The muiti-head design ensures even if one head malfunctions, the other head can still operate, which avoids downtime affecting the production process.Â
Average Daily Output of 3,000-10,000 CasesÂ
The sealing speed of Single-head automatic case sealer is 25-35 cases/minute, which satisfies the demand of medium-scale production and does not have complex design of multi-head models.Â
It automatically adjusts the size and flexibly switches production. The price is approximately 60-70% of that of the high speed model, but it offers 80% of its performance, which is a cost-effective choice.
Average Daily Output < 3,000 CasesÂ
For companies with small production scale, we recommend manual adjustment case sealer or medium-speed automatic case sealer with a speed of 15-20 cases/minute. It has a low initial investment cost and the investment can be recovered within 6-10 months.Â
Energy Conservation and Environmental ProtectionÂ
Energy conservation and environmental protection have become a trend in many industries. High speed case sealers that save energy, reduce noise and decrease exhaust emissions directly reduce operating costs and help establish a green image for companies.
The servo motor of the high speed case sealer uses the IE3 energy efficiency level, which saves 10-15% energy than ordinary motors. Its thickened body and precisely designed gears keep operating noise at ≤ 72 dB, which improves the working environment for employees and enhances work efficiency.
