[0024] like Figures 1 to 4 As shown in the figure, a cleaning device for a fully automatic hot stamping and die cutting machine includes a workbench 1 and a cleaning cavity 2 opened on the workbench 1. The inner wall surface of the cleaning cavity 2 is semi-circular. Two "冂"-shaped brackets 3 are mirror-mounted on the top of the workbench 1. A fixed plate 4 is arranged below the bracket 3. Three extrusion rollers 6 are arranged inside the fixed plate 4. Linkage parts 8 for driving the extrusion rollers 6 to rotate are arranged on the upper and lower inner wall surfaces of the fixed plate 4. A hydraulic cylinder 5 for moving the fixed plate 4 is arranged on the top of each bracket 3. A chip discharge port 9 for discharging chips is opened at the bottom of the cleaning cavity 2. A cleaning part 10 for pushing the chips to the chip discharge port 9 is arranged in the inner cavity of the cleaning cavity 2. A distance-changing part 11 for adjusting the distance between the two fixed plates 4 is arranged on the top of the workbench 1. A cleaning brush 7 for cleaning the chips on the surface of the printed matter is arranged on the side wall surface of the bracket 3;

[0025] In order to prevent the cleaning brush 7 from rubbing against the fixed plate 4 or the extrusion roller 6 when cleaning the printed matter, a distance of one to two centimeters is left between the rear wall surface of the cleaning brush 7 and the outer wall surface of the extrusion roller 6, and the distance between the front and rear corresponding cleaning brushes 7 is the same as the distance between the front and rear corresponding extrusion rollers 6;

[0026] In order to ensure that when the front and rear corresponding extrusion rollers 6 clamp and fix the printed matter, the printed matter will not collide and rub against the outer wall surface of the fixed plate 4, the distance between the two front and rear corresponding extrusion rollers 6 is 1.2 times the distance between the adjacent sides of the two fixed plates 4;

[0027] In order to improve the cleaning thoroughness and completion rate of the printed matter discharged on the right side, the brush hair density of the multiple cleaning brushes 7 gradually increases from left to right in sequence;

[0028] Specifically, by driving the hydraulic cylinder 5, the fixed plate 4 can be driven to move downward, and the printed matter clamped between the front and rear corresponding extrusion rollers 6 can be moved into the cleaning cavity 2. At the same time, the arranged linkage part 8 can drive the extrusion rollers 6 to rotate, so as to drive the clamped printed matter to move horizontally. During the horizontal movement of the printed matter, the outer surface of the printed matter can contact the cleaning brush 7, so that the arranged cleaning brush 7 can clean the surface of the printed matter. The swept chips can fall to the bottom of the cleaning cavity 2 under the action of gravity. The arranged cleaning part 10 can push the chips accumulated in the inner cavity of the cleaning cavity 2 to the chip discharge port 9 during the up and down movement of the fixed plate 4, so that the chips can be completely discharged from the chip discharge port 9, and at the same time, part of the chips attached to the inner wall surface of the cleaning cavity 2 can be scraped off, avoiding excessive chip adhesion and increasing the subsequent cleaning burden; when clamping and cleaning printed matter of different thicknesses, the arranged distance-changing part 11 can adjust the distance between the two brackets 3, so as to adjust the distance between the front and rear corresponding extrusion rollers 6 to a suitable clamping size, improving the practicability of the device.

[0029] Such as Figure 3 As shown, the linkage part 8 includes a hydraulic motor 801, and the upper and lower ends of each squeezing roller 6 are fixedly connected with a pulley 802, and the other end of the pulley 802 is rotatably connected to the inner wall surface of the fixed plate 4. The fixed plate 4 is internally installed with a hydraulic motor 801 for driving the left pulley 802 to rotate, and a belt 803 is wound between two adjacent pulleys 802;

[0030] Specifically, by driving the hydraulic motor 801, the left pulley 802 can be driven to rotate. With the cooperation of the belt 803, the other two squeezing rollers 6 can be pulled to rotate under the action of friction, thereby driving the printed matter clamped by the squeezing rollers 6 to move horizontally, so that it can contact the cleaning brush 7 during the movement to perform cleaning operations.

[0031] like Figure 2 As shown, the cleaning part 10 includes two gears 102, the front and rear inner wall surfaces of the cleaning chamber 2 are rotatably connected with the gears 102, a horizontal shaft 101 is fixedly installed on the adjacent side of the two gears 102, a rack 103 meshing with the gear 102 is welded at the bottom of each fixed plate 4, and side plates 104 are correspondingly welded on the front and rear outer wall surfaces of the horizontal shaft 101, and scrapers 105 are installed at the movable ends of the two side plates 104;

[0032] Specifically, the gear 102 is arranged to rotate when the fixed plate 4 drives the rack 103 to move in the vertical direction, thereby driving the horizontal axis 101 to rotate. During the rotation of the horizontal axis 101, the scraper 105 can be driven to rotate, so that the scraper 105 can clean and scrape the inner wall surface of the cleaning chamber 2, so that the debris attached to the inner wall surface of the cleaning chamber 2 can be scraped and pushed down, and at the same time, during the movement of the scraper 105, the scraped debris can be pushed to the chip discharge port 9 for centralized discharge.

[0033] like Figure 4 As shown, the upper and lower walls of the scraper 105 are welded with positioning plates 106 that are symmetrical with the side plates 104, and the positioning plates 106 are fixedly connected to the side plates 104 by bolts 107;

[0034] Specifically, the scraper 105 can be fixedly mounted on the side plate 104 by the provided bolts 107. At the same time, it is also convenient to quickly disassemble the scraper 105 when the scraper 105 is damaged and needs to be replaced. The structure is simple and easy to operate.

[0035] like Figure 1 As shown, the pitch-changing part 11 includes a moving cavity 1101. The top of the workbench 1 is provided with two moving cavities 1101 for placing the lower end of the bracket 3. Two electric push rods 1102 for driving the bracket 3 to move horizontally forward and backward are mirror-imaged inside each moving cavity 1101.

[0036] Specifically, by driving the electric push rod 1102, the bracket 3 can be driven to move in the front-rear direction, so as to adjust the distance between the front and rear corresponding squeezing rollers 6 to a size suitable for clamping printed products, thereby improving the practicality of the device, and the structure is simple and easy to operate.

[0037] When in use, the operator can drive the bracket 3 to move in the front-to-back direction by driving the electric push rod 1102, so as to adjust the spacing between the front and rear corresponding squeezing rollers 6 to a suitable size for clamping printed products, and then push the printed products to be cleaned between the front and rear corresponding squeezing rollers 6. When the printed products are pushed in, the printed products can contact with the cleaning brush 7 on the far left to achieve the initial cleaning purpose. While the printed products are pushed in, the hydraulic motor 801 is driven to rotate the squeezing roller 6 under the action of the belt 803, so that the printed products can be completely moved to the vertical upper part of the cleaning chamber 2 under the squeezing action of the squeezing roller 6 during the process of being pushed in.

[0038] When the end of the printed product is located above the cleaning chamber 2, the hydraulic cylinder 5 is driven to drive the fixed plate 4 to move downward. During the movement of the fixed plate 4, the scraper 105 can be driven to rotate under the meshing cooperation of the rack 103 and the gear 102, so as to scrape and clean the inner wall surface of the cleaning chamber 2 to prevent the debris cleaned by the cleaning brush 7 from adhering to the inner wall surface of the cleaning chamber 2. At the same time, the debris can also be scraped to the chip discharge port 9 for centralized discharge. When the right end of the printed product moves to the cleaning brush 7 close to the right side, the hydraulic cylinder 5 is driven to drive the fixed plate 4 to move upward, so that when the right end of the printed product moves to the rightmost side of the cleaning chamber 2, the fixed plate 4 can be completely moved above the workbench 1, so that the printed product that has been cleaned can be removed under the cooperation of the squeezing roller 6 and the linkage part 8.

[0039] In summary: by driving the hydraulic cylinder 5, the fixed plate 4 can be driven to move downward, and the printed matter clamped between the front and rear corresponding squeezing rollers 6 can be moved to the inside of the cleaning chamber 2. At the same time, the linkage part 8 can drive the squeezing roller 6 to rotate, so as to drive the clamped printed matter to move horizontally. During the horizontal movement of the printed matter, the outer surface of the printed matter can contact the cleaning brush 7, so that the cleaning brush 7 can clean the surface of the printed matter, and the swept debris can fall to the bottom of the cleaning chamber 2 under the action of gravity. The cleaning part 10 can push the debris accumulated in the inner cavity of the cleaning chamber 2 to the chip discharge port 9 during the upward and downward movement of the fixed plate 4, so that the debris can be completely discharged from the chip discharge port 9. At the same time, part of the debris attached to the inner wall surface of the cleaning chamber 2 is also scraped off to avoid excessive debris attachment that increases the burden of subsequent cleaning.

[0040] When clamping and cleaning printed materials of different thicknesses, the distance between the two brackets 3 can be adjusted by the variable distance portion 11, so that the distance between the front and rear corresponding squeezing rollers 6 can be adjusted to a suitable clamping size, thereby improving the practicability of the device.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
