Description

Technical Field

[0001] The utility model relates to the technical field of slitting processing, in particular to a hot-pressing and slitting device for shopping bags. Background Art

[0002] A slitter is a mechanical device that slits wide-width paper, mica tape or film into multiple narrow-width materials, and is commonly used in papermaking machinery, wire and cable mica tape, and printing and packaging machinery; a hot-pressing slitter can also be used to slit the material film of shopping bags.

[0003] There is a existing hot-pressing slitter for shopping bags (its authorization announcement number is: CN218430245U), and this hot-pressing slitter for shopping bags: the material film of the inclined pressing structure is respectively flattened towards the front and rear ends along the inclined angle, so that the material film passing through the cutting mechanism will not have too many wrinkles, and thus the material film after being slit by the cutting mechanism is flatter.

[0004] However, in the actual use process, two pressure rollers are used to tighten and flatten the material film of the shopping bag conveyed on the top side of the conveyor belt. When multiple blades on the hot-pressing slitter slit the material film of the shopping bag conveyed on the conveyor belt, the blades are likely to cause scratches on the surface of the conveyor belt, resulting in damage to the conveyor belt; therefore, we propose the present utility model to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Refer to Figures 1-4 , a hot pressing and slitting device for shopping bags, including a hot pressing and slitting machine 1. Two conveyor belts 2 are arranged on the top side of the hot pressing and slitting machine 1. A fixing frame 3 is fixedly installed on the top side of the hot pressing and slitting machine 1. A supporting roller 4 is rotatably installed on the inner wall of the fixing frame 3. A plurality of cutting grooves 5 are formed on the surface of the supporting roller 4. Two lifting grooves 6 are formed on the fixing frame 3. The same lifting frame 7 is movably installed in the two lifting grooves 6. A plurality of cutting blades 10 are arranged in the lifting frame 7. The bottom ends of the plurality of cutting blades 10 respectively extend into the corresponding cutting grooves 5. A slitting driving mechanism for the plurality of cutting blades 10 is arranged on one side of the lifting frame 7. Side roller frames 11 are arranged on both sides of the lifting frame 7. Pressing rollers 12 are rotatably installed in the two side roller frames 11. The bottom ends of the two pressing rollers 12 respectively abut against the top sides of the corresponding conveyor belts 2. A plurality of hinge mechanisms are arranged between the lifting frame 7 and the side roller frames 11. A plurality of elastic connection mechanisms for the two side roller frames 11 are arranged on the top side of the lifting frame 7.

[0022] Furthermore, the top contact surface of the roller body of the supporting roller 4 is level with the top surfaces of the two conveyor belts 2. A plurality of cutting grooves 5 on the surface of the supporting roller 4 are arranged at equal intervals, facilitating the transportation of the lifting frame 7 on the two lifting frames 7 and the supporting roller 4. At the same time, when the bottom parts of the plurality of cutting blades 10 extend into the corresponding cutting grooves 5 on the supporting roller 4, it is convenient to achieve a thorough cutting operation on the shopping bag material film.

[0023] Specifically, two cylinders 18 are fixedly installed on the top side of the fixed frame 3. The output ends of the two cylinders 18 respectively extend into the corresponding lifting grooves 6 in a movable manner and are fixedly installed on the top side of the lifting frame 7. By starting the two cylinders 18, the lifting adjustment of the lifting frame 7 can be realized.

[0024] Specifically, the slitting drive mechanism includes a motor 8 and a drive rod 9. A motor 8 is fixedly installed on one side of the lifting frame 7. One end of a drive rod 9 is fixedly installed at the output end of the motor 8, and the other end of the drive rod 9 is rotatably installed on the inner wall of one side of the lifting frame 7. The drive rod 9 is fixedly connected to the plurality of cutting blades 10. By starting the motor 8, the drive rod 9 drives the plurality of cutting blades 10 to rotate.

[0025] Specifically, the hinge mechanism includes a first hinge seat 13, a second hinge seat 14, and a hinge plate 15. The first hinge seat 13 is fixedly installed on one side of the lifting frame 7, and the second hinge seat 14 is fixedly installed on the top side of the corresponding side roller frame 11. The same hinge plate 15 is hingedly installed between the first hinge seat 13 and the second hinge seat 14. Under the action of multiple groups of hinge mechanisms, it is convenient for the two side roller frames 11 to move away from each other on both sides of the lifting frame 7.

[0026] Specifically, the elastic connection mechanism includes a V-shaped barrel sleeve 16 and a spring 17. The same spring 17 is fixedly installed on the top sides of the two side roller frames 11, and the V-shaped barrel sleeve 16 is fixedly installed on the top side of the lifting frame 7. The V-shaped barrel sleeve 16 is sleeved on the middle part of the spring 17; when the two side roller frames 11 move away from each other on both sides of the lifting frame 7, the three springs 17 between the two side roller frames 11 are deformed and stretched under force.

[0027] During use: When using the hot-pressing and slitting machine 1 to slit the shopping bag material film, the two conveyor belts 2 on the hot-pressing and slitting machine 1 convey the shopping bag material film. By starting the two cylinders 18, the lifting frame 7 is driven to move downward in the two lifting grooves 6. When the bottoms of the two pressure rollers 12 first abut against the shopping bag material film on the two conveyor belts 2, the two pressure rollers 12 roll downward under pressure on the corresponding conveyor belts 2 and move away from each other, causing the three springs 17 between the two side roller frames 11 to be deformed and stretched. Thus, the shopping bag material film is tensioned by the rolling downward movement of the two pressure rollers 12 moving away from each other. At the same time, by starting the motor 8, the driving rod 9 drives the multiple cutting blades 10 to rotate. As the multiple cutting blades 10 continue to move downward, when the multiple cutting blades 10 move downward and contact the tensioned shopping bag material film, the slitting operation of the shopping bag material film is realized. The bottom parts of the multiple cutting blades 10 extend into the corresponding cutting grooves 5 on the support roller 4, facilitating the thorough slitting operation of the shopping bag material film and avoiding the situation of scratching and damaging the surface of the conveyor belt 2 when slitting the shopping bag material film.
