Description

Technical Field

[0001] The utility model relates to a gasket replacement device for heat sealing. Background Art

[0002] An air column bag, also known as a buffer air column bag, an inflatable bag, a bubble column bag, or a columnar inflatable bag, is a new type of packaging material filled with natural air in the 21st century; the inflatable bag has a wide range of applications, and as long as it is related to packaging and products that need to be transported at the same time, the air column bag can be used.

[0003] When processing an air column bag, it is necessary to heat-seal an air column film, and different folding parts are formed through heat-sealing, so that the air column film can be folded into different shapes after inflation; when heat-sealing, a gasket needs to be arranged between two heat-sealing platforms to prevent the high temperature of the heat-sealing platform from damaging the surface of the air column film. After long-term use, the gasket will be damaged and needs to be replaced; when replacing the gasket, it is necessary for workers to remove the old gasket and then reinstall the new gasket. In this process, the fixing rod of the gasket needs to be disassembled and reinstalled, which is time-consuming and laborious. Summary of the Utility Model

[0006] Furthermore, the linkage assembly includes a rubber sleeve and an annular transmission belt. The rubber sleeve is sleeved on the ends of the first mounting rod and the second mounting rod far away from the rotation driving group. One end of the annular transmission belt acts on the rubber sleeve of the first mounting rod, and the other end of the annular transmission belt acts on the rubber sleeve of the second mounting rod. The first mounting rod and the second mounting rod can rotate synchronously under the tensioning action of the rubber sleeve of the first mounting rod and the rubber sleeve of the second mounting rod on the annular transmission belt.

[0007] Furthermore, the linkage assembly includes a gear sleeve and a chain. The gear sleeve is sleeved on the ends of the first mounting rod and the second mounting rod away from the rotation driving group. One end of the chain acts on the gear sleeve of the first mounting rod and forms an engagement, and the other end of the chain acts on the gear sleeve of the second mounting rod and forms an engagement. The first mounting rod and the second mounting rod can rotate synchronously due to the engagement of the two ends of the chain with the corresponding gear sleeves.

[0008] Furthermore, the rotation driving group includes a main driving device and a speed reduction device. The driving end of the main driving device is fixedly connected to the input end of the speed reduction device. A first gear is fixedly provided at the output end of the speed reduction device.

When the first mounting rod 22 and the second mounting rod 23 rotate, the gasket on the gasket roller can be rolled and replaced on the first mounting rod 22 and the second mounting rod 23, replacing the old gasket with a new one, without manual replacement, which is efficient and convenient.

[0025] The gasket is located between the first heat-sealing table 21 and the second heat-sealing table 11 and tightly abuts against the lower end of the first heat-sealing table 21. Teflon material can be used as the gasket.

[0026] The linkage assembly 4 comprises a rubber sleeve 41 and an annular transmission belt 42. The rubber sleeve 41 is sleeved on the ends of the first mounting rod 22 and the second mounting rod 23 far away from the rotation driving group 3.

[0037] Working principle of the present utility model: When it is necessary to replace the gasket between the first heat-sealing table 21 and the second heat-sealing table 11, through the drive of the main drive device 31, after deceleration by the deceleration device 32, the first gear 321 meshes with the second gear 5 to drive the first mounting rod 22 or the second mounting rod 23 to rotate. At this time, the first mounting rod 22 or the second mounting rod 23 rotates synchronously and in the same direction through the linkage effect of the linkage assembly 4. The gasket roller on the first mounting rod 22 releases a new gasket, and the second mounting rod 23 winds up the old gasket, so that the new gasket on the gasket roller is transferred between the first heat-sealing table 21 and the second heat-sealing table 11. When the new gasket completely replaces the old gasket, the main drive device 31 stops running; during this process, due to the synchronous and co-directional rotation of the first mounting rod 22 or the second mounting rod 23, the tension of the gasket remains consistent.

[0038] In the above specific embodiments, the purpose, technical solution and beneficial effects of the present utility model have been further described in detail. It should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model.
