Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Example

[0029] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0030] The anti-static EVA sheet rewinding device comprises a base 1, a rewinding device body 2 is arranged on the top of the base 1, a rewinding assembly 3 is arranged on the front of the rewinding device body 2, a rolling chamber 4 is arranged inside the rewinding device body 2 and on a side close to the rewinding assembly 3, and a cleaning chamber 5 is arranged behind the rolling chamber 4;

[0031] Among them, two groups of rotating plates 101 are fixedly connected at the back of the rewinding device body 2 and at the position corresponding to the rewinding assembly 3, and a conveying roller 102 is rotatably connected between the two groups of rotating plates 101.

A partition plate 8 is fixedly connected between the rolling chamber 4 and the cleaning chamber 5, and a through hole 801 is opened on the inner side of the partition plate 8;

[0032] Two groups of extrusion belts 401 are rotatably connected inside the rolling chamber 4, and connecting sleeves 402 are rotatably connected inside the rolling chamber 4 and on both the front and rear sides located inside the two groups of extrusion belts 401;

[0033] The inside of the discharge port 6 and the feed port 7 are connected to the rolling seat 602 through three groups of buffer springs 601, the inside of the two groups of rolling seats 602 are rotatably connected to the upper rolling shaft 603, and the inside of the discharge port 6 and the feed port 7 and below the two groups of upper rolling shafts 603 are rotatably connected to the lower rolling shaft 604.

[0034] Specifically, first, the rewinding device body 2 is placed above the base 1, and the EVA sheet is fed through the feed port 7. At this time, the conveying roller 102 rotates in the two sets of rotating plates 101, and then the EVA sheet is guided by the conveying roller 102, and the EVA sheet is conveyed to the inside of the rewinding device body 2, and the surface of the EVA sheet is cleaned through the cleaning chamber 5 in the rewinding device body 2, and the dust on the surface of the EVA sheet is swept off, and at the same time, the extrusion belt 401 is driven by the connecting sleeve 402 in the rolling chamber 4. The EVA sheet is rotated and then rolled by the extrusion belt 401 to flatten the wrinkles on the surface of the EVA sheet, and then the EVA sheet is led out from the rewinding device body 2 through the discharge port 6. The rolling seat 602 is squeezed by the buffer spring 601 during feeding and discharging, and then the EVA sheet is squeezed by the rolling seat 602, and the EVA sheet is squeezed by the upper rolling shaft 603 and the lower rolling shaft 604. The EVA sheet is rolled by the extrusion of the upper rolling shaft 603 and the lower rolling shaft 604, and the EVA sheet is rewound by the rewinding component 3.

[0035] Then, see Figure 2 , Figure 3 , Figure 4 as well as Figure 6 , a rewinding assembly 3 is provided on the front of the rewinding device body 2;

[0036] The rewinding component 3 is used to limit the rewinding of the EVA sheet. The specific structure of the rewinding component 3 is as follows:

[0037] The rewinding assembly 3 includes two groups of rewinding plates 301, a rewinding roller 302, a limit motor 303, a driving gear 304, a driven gear 305, a bidirectional screw rod 306 and a limit plate 307. The two groups of rewinding plates 301 are respectively rotatably connected to the front side of the rewinding device body 2. The inside of the two groups of rewinding plates 301 is fixedly connected with four groups of rewinding rollers 302. The outer side of the rewinding plate 301 and at the position corresponding to the rewinding roller 302 is provided with a limit motor 303. The limit motor 303 is meshed and connected with the driven gear 305 through the driving gear 304. The driven gear 305 is threadedly connected to the limit plate 307 through the bidirectional screw rod 306. The two groups of limit plates 307 are respectively slidably connected between the two groups of rewinding plates 301 and are located on the outer sides of the four groups of rewinding rollers 302. The front side of the rewinding device body 2 and at the positions corresponding to the two groups of rewinding plates 301 are fixedly connected with mounting plates.

[0038] Specifically, the EVA sheet is rewound by the rewinding component 3, and a driving motor is installed on the outer side of the mounting plate and at a position corresponding to the rewinding plate 301. The rewinding plate 301 is driven to rotate by the driving motor, and then the rewinding roller 302 is driven to rotate by the rewinding plate 301. The EVA sheet is rewound by the rotation of the rewinding roller 302. When in use, the driving gear 304 can also be driven to rotate by the limiting motor 303. The driving gear 304 drives the driven gear 305 to rotate when rotating, and the driven gear 305 drives the bidirectional lead screw 306 to rotate. The bidirectional lead screw 306 drives the two sets of limit plates 307 to move on the rewinding roller 302 when rotating, so that the two sets of limit plates 307 are close to or away from each other, and the distance between the two sets of limit plates 307 is adjusted to a suitable length, so that the EVA sheet can be limited.

[0039] Finally, see Figure 2 and Figure 5 , a cleaning room 5 is opened behind the rolling room 4;

[0040] The cleaning room 5 is used to perform deep cleaning on both sides of the surface of the EVA sheet. The specific structure of the cleaning room 5 is as follows:

[0041] Four groups of guide rollers 501 are rotatably connected inside the cleaning chamber 5, three groups of cleaning seats 502 are fixedly connected inside the cleaning chamber 5, a number of cleaning brushes 503 are fixedly connected to the inner sides of the three groups of cleaning seats 502 and at positions corresponding to the guide rollers 501, two groups of cleaning rollers 504 are rotatably connected inside the cleaning chamber 5 and located on the inner sides of the three groups of cleaning seats 502, cleaning pads are fixedly connected to the outer sides of the two groups of cleaning rollers 504, two groups of cleaning frames 505 are fixedly connected to the rear of the three groups of cleaning seats 502, three groups of supporting seats 506 are fixedly connected inside the two groups of cleaning frames 505, and cleaning sponges 507, scraper brushes 508 and scrapers 509 are fixedly connected inside the three groups of supporting seats 506.

[0042] Specifically, the EVA sheet is guided by the guide roller 501 in the cleaning chamber 5, and the surface of the EVA sheet is cleaned by the cleaning brush 503 on the outside of the cleaning seat 502, and at the same time, the cleaning roller 504 cleans the other side of the EVA sheet through the cleaning pad on the outside, so that both sides of the EVA sheet can be cleaned, and then the EVA sheet is poured into the cleaning rack 505, and the scraper 509 in the cleaning rack 505 scrapes off the dust adhered to the surface of the EVA sheet, so that the dust falls into the cleaning rack 505, and at the same time, the scraper brush 508 can sweep down the scraped dust, and the cleaning rack 505 collects the dust, and the cleaning sponge 507 can absorb the dust on the surface of the EVA sheet.

[0043] In this embodiment, the implementation scenario is specifically as follows: in actual use, first, the rewinding device body 2 is placed above the base 1, and the EVA sheet is fed through the feed port 7. At this time, the conveying roller 102 rotates in the two sets of rotating plates 101, and then the EVA sheet is guided by the conveying roller 102, and the EVA sheet is conveyed to the inside of the rewinding device body 2, and the surface of the EVA sheet is cleaned through the cleaning chamber 5 in the rewinding device body 2, and the dust on the surface of the EVA sheet is swept off, and at the same time, the extrusion belt 401 is driven to rotate through the connecting sleeve 402 in the rolling chamber 4, and then the extrusion belt 401 is driven to rotate through the extrusion belt 401. The belt 401 rolls the EVA sheet to flatten the wrinkles on the surface of the EVA sheet, and then the EVA sheet is led out from the rewinding device body 2 through the discharge port 6. When feeding and discharging, the buffer spring 601 squeezes the rolling seat 602, and then the EVA sheet is squeezed by the rolling seat 602, and the upper rolling shaft 603 squeezes the EVA sheet on the lower rolling shaft 604. The EVA sheet is rolled by squeezing the upper rolling shaft 603 and the lower rolling shaft 604, and the EVA sheet is rewound by the rewinding component 3. Compared with the existing rewinding device, the utility model can improve the overall practicality of the rewinding device through design.
