Description

TECHNICAL FIELD

[0001] The utility model relates to the field of calabash membrane inflation, especially to a calabash membrane inflation device. BACKGROUND

[0002] Calabash membrane is a transparent film made of high molecular polyethylene material, which becomes a protective material composed of multiple bubbles after being inflated by inflation equipment. Calabash membrane has been widely used in the field of logistics packaging due to its unique design and excellent performance, especially in the transportation packaging of fragile, pressure-resistant and shock-resistant goods.

[0003] In the Chinese utility model patent with the patent number CN221274411U, a dual-purpose automatic inflator with anti-winding function is proposed. The elastic sheet drives the clamping plate to clamp into the tooth plate through the round sleeve and sleeve to fix the anti-winding guide plate. The anti-winding guide plate supports and guides the calabash membrane or air column bag, achieving the advantage of anti-winding. The calabash membrane and air column bag are not prone to winding and folding.

[0004] However, this type of technical solution has a problem. Since the working mechanism is upright, the calabash membrane roll is also placed upright. During the inflation process, the upright calabash membrane will sag to one side due to gravity and at a large angle, causing the inflation and sealing end of the calabash membrane to deflect and resulting in irregular sealing lines. Utility model content

[0005] The utility model provides a calabash membrane inflation device. By setting the working mechanism laterally and rotating the membrane roll horizontally, the angle of film sagging is reduced, solving the problem of irregular sealing lines.

[0006] To solve the above technical problems, the utility model provides a calabash membrane inflation device, which includes a rack, a membrane roll holder, and an inflation device. The membrane roll holder and the inflation device are arranged on the side surface of the rack. The inflation device includes an inflation nozzle, a sealing wheel set, and a cutter. A blower is arranged inside the rack. The air outlet of the blower is connected to the inflation nozzle. The inflation nozzle extends out of the rack. The cutter is arranged between the rack and the inflation nozzle. The sealing wheel set is arranged behind the inflation nozzle. The sealing wheel set includes two rollers with contacting wheel surfaces.

[0007] Generally, the low-cost cushion material such as the gourd film does not have the function of the air valve film, that is, the air locking function. The air inlet of the gourd film needs to be sealed immediately after the inflation is completed. The process requires special designed equipment. The common process is to set the air inlet channel of the gourd film on the inflation nozzle, and then use the sealing equipment to seal after the gourd film is inflated. The steps are relatively complicated. The film roll holder and the inflation device are arranged on the side of the rack, and the sealing wheel group for sealing the gourd film is arranged behind the inflation nozzle. The cutting knife can cut the air inlet channel set on the inflation nozzle. By adopting such a scheme, the continuous operation of the gourd film inflation and sealing is realized. After the working mechanism is arranged laterally, the film roll rotates horizontally, the angle of the film sagging is reduced, and the problem of irregular sealing line is solved.

[0008] As preferred, at least one of the rollers of the sealing wheel group is provided with a sealing ironing channel. By adopting the form of inlaying the heating ring on the roller, the continuous operation process of pulling and sealing is realized, and the inflation efficiency of the gourd film is improved.

[0009] Further, the outer side of the roller is provided with a nylon cladding layer. The nylon cladding layer is relatively soft, and the contact surface of the two rollers will produce a certain elastic deformation. This elastic deformation can provide strong friction to prevent slipping when pulling the gourd film, and improve the reliability of the mechanism.

[0010] As preferred, at least one air outlet hole is arranged on the side of the inflation nozzle. The air outlet hole is horizontally arranged, and the air outlet hole is located in front of the cutting knife. Based on the characteristics of the gourd film without air valve film, a certain pressure is not needed in the air inlet channel to allow air inflow. The air inflow mode is different. Such air outlet hole design can ensure that each part needing inflation is sealed after obtaining sufficient gas, thereby improving the air inflow of the gourd film.

[0011] Further, a tapered nylon plug is arranged at the end of the inflation nozzle. The tapered design can facilitate insertion into the air inlet channel, and can prevent the air inlet channel from being pierced during continuous inflation, thereby preventing work interruption and improving the stability of continuous operation.

[0012] As preferred, the auxiliary roller group is further included. The auxiliary roller group includes two auxiliary wheels in contact with each other, and the auxiliary roller group is arranged behind the sealing wheel group. The auxiliary roller group can help cut the air inlet channel, realize further automatic inflation and sealing of the gourd film, and further improve the stability of continuous operation.

[0013] As preferred, the film roll holder includes a film roll expansion sleeve. The film roll expansion sleeve is arranged on the end side of the rack. The film roll expansion sleeve is provided with a tension piece at the end. In continuous operation, the rotation stability of the gourd film roll is very important. The film roll expansion sleeve can stably clamp the gourd film roll on the film roll holder, thereby improving the stability of continuous operation.

[0014] As preferred, the film roll frame further comprises a film arranging frame, which is arranged between the inflation nozzle and the film roll expansion sleeve, and is parallel to the inflation nozzle. In the continuous pulling of the gourd-shaped film roll on the film roll frame, the gourd-shaped film roll will continue to rotate by a certain angle, and a section of the un-inflated gourd-shaped film will fall off. When the inflation is started again, the angle of the un-inflated gourd-shaped film is not correct, and the inflation nozzle is likely to pierce the gourd-shaped film. After the film arranging frame is used, the inflation nozzle and the gourd-shaped film always maintain a horizontal angle, which greatly reduces the risk of being pierced, and further improves the stability of continuous operation

[0015] As preferred, the machine frame is provided with an emergency stop switch. The length of the gourd-shaped film used each time can be inconsistent, and the emergency stop switch can stop sealing and capping in time, and take the appropriate amount of gourd-shaped film, thereby reducing the waste of packaging.

[0016] As preferred, the machine frame is provided with a handle. The device has a small size and light weight, and the handle improves the portability of the device.

[0017] By adopting the scheme, the work mechanism is arranged laterally, the film roll rotates horizontally, the angle of the film sag is greatly reduced, the problem of irregular sealing lines is solved, and the portability of the device is realized. BRIEF DESCRIPTION OF DRAWINGS
