Description

Technical Field

[0001] The utility model relates to the technical field of slitter roller bodies, and specifically relates to a main drive adsorption roller of a slitter. Background Art

[0002] A slitter is a mechanical device used to slit wide-width materials into multiple narrow-width materials, and is widely used in industries such as papermaking, printing, packaging, plastics, metal foils, and composite materials. The main function of a slitter is to cut large rolls of wide-width materials into strips or small rolls of the required width to meet the requirements of downstream production or final use; the adsorption roller of a slitter is an important component in the slitter. Its main role is to provide support and stability for the material during the slitting process, and to ensure the correct position of the material during the cutting process. Adsorption rollers are usually used to adsorb and guide materials through the slitter. They generate a certain vacuum suction force to tightly adsorb the materials on the roller surface, preventing the materials from shifting, wrinkling or deforming during high-speed operation.

[0003] There are certain limitations in the operation of the existing main drive adsorption roller of a slitter. Specifically, when the adsorption roller performs a vacuum pumping operation to fix the material, the vacuum pipeline connecting the pump body and the adsorption roller often has a problem of pipeline entanglement. This problem not only affects the working efficiency and stability of the slitter, but may also cause damage to the vacuum system, thereby increasing the maintenance cost and downtime.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of 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.

[0030] Please refer to Figures 1 to 10, in the embodiment of the present utility model, a main drive adsorption roller of a slitter includes a support frame 1. Above the support frame 1, there is an adsorption roller body 2. On the left side of the adsorption roller body 2, there are an air extraction mechanism 3 and a winding mechanism 4. The air extraction mechanism 3 includes an air extraction pipe 301, a snap ring 302, an outer shaft ring body 303, and an inner shaft ring body 306. A snap ring 302 is fixedly installed at the left end of the adsorption roller body 2. Inside the snap ring 302, there is an outer shaft ring body 303. Inside the outer shaft ring body 303, there is an inner shaft ring body 306. The air extraction pipe 301 is fixedly inserted on the inner shaft ring body 306. The air extraction mechanism 3 further includes a first annular groove 304, a ball body 305, a second annular groove 307, a sealing gasket ring 308, a positioning column body 309, a mounting frame 310, and a vacuum pump body 311. A first annular groove 304 is formed on the inner wall of the outer shaft ring body 303. A second annular groove 307 is formed on the outer wall of the inner shaft ring body 306. The ball body 305 is filled between the second annular groove 307 and the first annular groove 304. Inside the inner shaft ring body 306, there is a sealing gasket ring 308. The sealing gasket ring 308 is clamped on the driving rod 402. A positioning column body 309 is fixedly installed on the outer wall of the inner shaft ring body 306. A mounting frame 310 is fixedly installed on the outer wall of the positioning column body 309. The mounting frame 310 is fixedly installed on the support frame 1. One end of the air extraction pipe 301 away from the inner shaft ring body 306 is fixedly connected to the vacuum pump body 311;

[0031] The air extraction pipe 301 enables the air extraction mechanism 3 to be effectively connected to the adsorption roller body 2 without causing pipeline entanglement due to the rotation of the adsorption roller body 2. Due to the relative static state of the inner shaft ring body 306, the air extraction pipe 301 avoids the entanglement problem during the rotation of the adsorption roller body 2, ensuring long-term stable operation; the independent rotation of the outer shaft ring body 303 reduces the interference with the inner shaft ring body 306, improves the reliability of the air extraction mechanism 3, provides stability for the air extraction pipe 301, and avoids damage caused by vibration. The inner shaft ring body 306 keeps the air extraction mechanism 3 in a relatively static state, ensuring the stability of the air extraction mechanism 3 during the rotation of the adsorption roller body 2 and reducing the wear caused by movement;

[0032] The winding mechanism 4 includes a driving motor 401 and a driving rod 402. The driving end of the driving motor 401 is fixedly installed with the driving rod 402. The winding mechanism 4 further includes a connecting rod body 403, a support rod 404, a collar bearing 405, a bearing bracket 406 and a rubber gasket 407. The connecting rod body 403 is fixedly installed on the outer wall of the driving rod 402. Multiple groups of connecting rod bodies 403 are distributed on the outer wall of the driving rod 402 from left to right. The right end of the adsorption roller body 2 is fixedly installed with a support rod 404. A collar bearing 405 is arranged outside the support rod 404. A bearing bracket 406 is arranged outside the collar bearing 405. The bearing bracket 406 is fixedly installed on the support frame 1. The rubber gasket 407 is fixedly installed on the outer wall of the adsorption roller body 2. Air grooves are formed in the rubber gasket 407. The driving motor 401 provides a power source for the winding mechanism 4. The rubber gasket 407 increases the friction between the material and the adsorption roller body 2, improves the grasping force of the adsorption roller body 2 on the material, and prevents the material from sliding.

[0033] The working principle of the present utility model is as follows: The main transmission adsorption roller of this slitter is composed of a support frame 1, an adsorption roller body 2, an air extraction mechanism 3 and a winding mechanism 4. Before using the main transmission adsorption roller of this slitter, it is necessary to pre-connect the vacuum pump body 311 and the driving motor 401 to the power supply and connect them to the control terminal. When using the main transmission adsorption roller of this slitter, the air extraction mechanism 3 and the winding mechanism 4 are enabled. The driving motor 401 is started to drive the driving rod 402, the connecting rod body 403 and the adsorption roller body 2 to rotate, realizing the effects of coiling and pulling the material. During the rotation of the adsorption roller body 2, the outer shaft ring body 303 will also rotate accordingly, and the rotation effect of the outer shaft ring body 303 will not affect the inner shaft ring body 306. Furthermore, the air extraction pipeline 301 inserted on the inner shaft ring body 306 will not be affected by the rotation of the adsorption roller body 2. With the auxiliary effects of multiple components such as the snap ring 302, the outer shaft ring body 303, the inner shaft ring body 306, the first annular groove 304, the ball body 305, the second annular groove 307 and the sealing gasket ring 308, the rotation effects of the outer shaft ring body 303 and the inner shaft ring body 306 can be ensured, and an effective sealing effect can be provided. At this time, the vacuum pump body 311 is started to extract the gas inside the adsorption roller body 2 through the air extraction pipeline 301, realizing a negative pressure effect, and then the material is adsorbed on the adsorption roller body 2. In addition, the rubber gasket 407 installed on the outer wall of the adsorption roller body 2 can also provide a certain adsorption effect. To sum up, the air extraction mechanism 3 adopts a stable air guiding structure and a bearing sliding structure, which can stably extract the gas inside the adsorption roller body 2, realize a negative pressure effect, and then enable the adsorption roller body 2 to adsorb the material, effectively avoiding the situation that the rotation of the adsorption roller body 2 will damage the vacuum pump body 311, improving the reliability of use of the adsorption roller body 2. The winding mechanism 4 is driven by a motor to realize the effect of winding the adsorption roller body 2 and can guide the material.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
