Description

Technical Field

[0001] This utility model relates to the technical field of membrane material manufacturing, and in particular to an automatic cleaning device for a laminating machine. Background Technology

[0002] In modern packaging, printing, and many other industrial fields, laminating machines play a crucial role. They can laminate various materials such as films and papers using adhesives to produce composite products with specific properties and uses, such as food packaging materials and labeling materials. With long-term operation, the gluing rollers inside the laminating machine, which frequently come into contact with adhesives and raw materials, easily accumulate adhesive residue, dust, impurities, and debris from raw materials. This residual adhesive not only affects the uniformity of subsequent gluing applications, leading to inconsistent bonding strength in the composite products and quality problems such as delamination and bubbling, but in severe cases, it can even alter the surface roughness of the gluing rollers, affecting their normal function. For example, Chinese patent document CN217963251U discloses a sleeve-type rubber roller connection structure for a laminating machine, including a left frame and a right frame. The upper rubber roller body is located between the left and right frames. A left bearing is installed on the connecting shaft at the left end of the upper rubber roller body, and the outer ring of the left bearing is fixed to the left frame. A right bearing is installed on the connecting shaft at the right end of the upper rubber roller body. A downwardly extending telescopic groove is formed in the middle of the top surface of the right frame, and a support block is inserted into the telescopic groove. An inwardly extending mounting groove is formed on the side wall of the right frame below the telescopic groove. This facilitates the disassembly and replacement of the adhesive coating outer sleeve, thereby improving replacement efficiency.

[0003] However, the existing sleeve-type glue roller connection structure for laminating machines has the following shortcomings in practical use: the glue coating jacket requires frequent machine shutdowns for replacement, resulting in low production efficiency. In view of this, the automatic cleaning device for laminating machines proposed in this application is proposed. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0033] like Figures 1 to 6As shown, in one embodiment, an automatic cleaning device 1 for a laminating machine includes an adhesive roller 10 for applying adhesive to the surface of a laser film, a frame 20, and a cleaning assembly 30. The adhesive roller 10 is rotatably mounted on the frame 20. The cleaning assembly 30 includes a cleaning plate 31, a scraper 32, a cleaning cotton 33, and two driving members 34. The two driving members 34 are mounted on the frame 20. Both ends of the cleaning plate 31 are rotatably connected to the two driving members 34, the scraper 32 is mounted on the cleaning plate 31, and the cleaning cotton 33 is mounted on the cleaning plate 31. The two driving members 34 simultaneously drive the cleaning plate 31 closer to the upper roller, so that the scraper 32 and the cleaning cotton 33 both abut against the upper roller.

[0034] It should be noted that the two ends of the upper roller are rotatably connected to the two opposite ends of the frame 20. Two drive members 34 are respectively disposed on both ends of one side of the frame 20, and the output shafts of both drive members 34 face the two ends of the upper roller 10. Furthermore, the two ends of the cleaning plate 31 are rotatably connected to the two drive members 34, so that the cleaning plate 31 is parallel to the upper roller 10. It should be noted that the two ends of one side of the cleaning plate 31 are rotatably connected to the output shafts of the drive members 34, allowing the cleaning plate 31 to swing relative to the drive members 34. Furthermore, a scraper 32 is disposed on the cleaning plate 31, and the scraper 32 extends to the two ends of the cleaning plate 31 near the two drive members 34. It should be noted that the end of the scraper 32 without a blade is located inside the cleaning plate 31, while the end of the scraper 32 with a blade extends outward from the cleaning plate 31. Furthermore, one end of the cleaning cotton 33 is mounted on the cleaning plate 31, and the other end of the cleaning cotton 33 extends outward from the cleaning plate 31. The cleaning cotton 33 is located below the scraper 32, and the extension distance of the cleaning cotton 33 is greater than the extension distance of the scraper 32. When the two driving components 34 simultaneously drive the cleaning plate 31 close to the glue roller 10, both the scraper 32 and the cleaning cotton 33 on the cleaning plate 31 come into contact with the glue roller 10. This causes the scraper 32 to remove the residual adhesive on the glue roller 10. Since the cleaning cotton 33 is located below the scraper 32, after the scraper 32 removes the residual adhesive on the glue roller 10, the cleaning cotton 33 wipes the glue roller 10 to ensure its cleanliness, thereby improving the production efficiency of film lamination.

[0035] like Figures 3 to 6 As shown, in one embodiment, the cleaning component 30 further includes a cotton clamping plate 35, which is rotatably disposed on the cleaning plate 31. The cotton clamping plate 35 and the cleaning plate 31 together form a cotton placement groove 351. One end of the cleaning cotton 33 is located in the cotton placement groove 351, and the other end of the cleaning cotton 33 abuts against the upper adhesive roller 10.

[0036] It should be noted that one end of the clamping plate 35 is rotatably connected to the cleaning plate 31. When the clamping plate 35 rotates to a parallel state with the cleaning plate 31, the clamping plate 35 and the cleaning plate 31 together form a cotton placement groove 351. One end of the cleaning cotton 33 is located in the cotton placement groove 351, so that the clamping plate 35 and the cleaning plate 31 can clamp one end of the cleaning cotton 33 together, while the other end of the cleaning cotton 33 extends out from the cotton placement groove 351. In this way, the cleaning plate 31 can move the cleaning cotton 33 closer to or away from the upper roller.

[0037] like Figure 1 , Figures 3 to 4 , Figure 6 As shown, in one embodiment, the cleaning assembly 30 further includes a plurality of water inlet connectors 36, and a plurality of water inlet holes 311 are provided on the cleaning plate 31. Each water inlet hole 311 extends from one side of the cleaning plate 31 into the cotton storage trough 351, and each water inlet connector 36 is respectively disposed on the end of each water inlet hole 311 away from the cotton storage trough 351.

[0038] It should be noted that the cleaning plate 31 has several water inlet holes 311, each extending from the side of the cleaning plate 31 away from the cotton storage trough 351 into the cotton storage trough 351. Water inlet connectors 36 are correspondingly arranged on each water inlet hole 311, and each water inlet connector 36 is located on the side of each water inlet hole 311 away from the cotton storage trough 351, so that each water inlet connector 36 is connected to the inside of the cotton storage trough 351. Furthermore, when each water inlet connector 36 is connected to a water pipe, water in the water pipe can flow into the cotton storage trough 351 through the water inlet connector 36 and the water inlet hole 311, thereby keeping the cleaning cotton 33 moist and improving the cleaning effect of the cleaning cotton 33 on the rubber roller 10.

[0039] In one embodiment, each water inlet connector 36 is connected to a container containing adhesive remover, so that the adhesive remover is evenly penetrated onto the cleaning cotton 33. Since the glue roller 10 is mounted on the frame 20, when the upper roller rotates, the cleaning cotton 33 can apply the adhesive remover onto the upper roller, so that the scraper 32 can better remove the adhesive residue on the glue roller 10, thereby improving the cleaning effect of the upper roller.

[0040] like Figures 1 to 4 As shown, in one embodiment, the driving component 34 includes a pushing cylinder 341 and a sliding block 342. The pushing cylinder 341 is disposed on the frame 20, and the sliding block 342 is slidably disposed on the frame 20. One end of the sliding block 342 is connected to the output shaft of the pushing cylinder 341, and one end of the cleaning plate 31 is rotatably connected to the end of the sliding block 342 away from the pushing cylinder 341.

[0041] It should be noted that there are two drive components 34. Both push cylinders 341 are located on one side of the frame 20, and the output shafts of both push cylinders face both ends of the upper rubber roller 10. Two sliding blocks 342 are respectively slidably mounted on two opposing inner sidewalls of the frame 20. One end of each sliding block 342 is connected to the output shaft of the two push cylinders 341. Both ends of the cleaning plate 31 are rotatably connected to the ends of the two sliding blocks 342 that are away from the push cylinders 341, so that the two push cylinders 341 can simultaneously drive the cleaning plate 31 to slide, so that the cleaning plate 31 drives the scraper 32 and the cleaning cotton 33 to move closer to or away from the upper rubber roller 10.

[0042] like Figures 1 to 2 As shown, in one embodiment, the drive unit 34 further includes a rotary motor 343, a support block 344, a main gear 345, and a driven gear 346. The support block 344 is disposed on the sliding shaft block 342, the rotary motor 343 is disposed on the support block 344, the main gear 345 is disposed on the output shaft of the rotary motor 343, and the driven gear 346 is disposed on one end of the cleaning plate 31, and the main gear 345 meshes with the driven gear 346.

[0043] It should be noted that the support block 344 is disposed on any one of the sliding shaft blocks 342, and the support block 344 is located at the end of the sliding shaft block 342 near the push cylinder 341, so that when the push cylinder 341 drives the sliding shaft block 342 to slide relative to the frame 20, the sliding shaft block 342 can drive the support block 344 to slide. Furthermore, the rotary motor 343 is disposed on the support block 344, the main gear 345 is disposed on the output shaft of the rotary motor 343, and the driven gear 346 is disposed on one end of the cleaning plate 31, and the driven gear 346 meshes with the main gear 345, so that the rotary motor 343 can drive the cleaning plate 31 to rotate. Thus, when residual adhesive on the glue roller 10 needs to be removed by first applying adhesive remover, the cleaning plate 31 is rotated upward by rotating the motor 343. The cleaning plate 31 drives the scraper 32 to rotate upward away from the glue roller 10, so that the cleaning cotton 33 located below the scraper 32 first comes into contact with the upper roller. This allows the adhesive remover on the cleaning cotton 33 to be applied to the glue roller 10 first, so that the residual adhesive can come into contact with the adhesive remover and soften. Then, by rotating the motor 343, the scraper 32 rotates downward and comes into contact with the glue roller 10, so that the scraper 32 scrapes off the softened residual adhesive. This improves the cleaning effect.

[0044] like Figures 1 to 6 As shown, in one embodiment, the cleaning assembly 30 further includes a pressure plate 37, which is disposed on the cleaning plate 31, and the pressure plate 37 and the cleaning plate 31 together clamp the scraper 32.

[0045] It should be noted that the cleaning plate 31 has a blade groove, one end of the scraper 32 is placed in the blade groove, and the other end of the scraper 32 extends out of the blade groove. The pressure plate 37 fixes the scraper 32 to the cleaning plate 31 with screws to prevent the scraper 32 from loosening or falling off.

[0046] like Figures 1 to 4 , Figure 7 As shown, in one embodiment, the cleaning assembly 30 further includes a waste tray 38, which is disposed on the support block 344 and located below the cleaning plate 31.

[0047] It should be noted that the waste tray 38 includes a tray body 381 and a grid 382. Two support blocks 344 are provided, each mounted on a sliding shaft block 342. The two ends of the tray body 381 are respectively mounted on the two support blocks 344. The grid 382 is located on the tray body 381, dividing it into a slag collection trough 3821 and a drainage trough 3822. The slag collection trough 3821 is located below the scraper 32 and the cleaning cotton 33, and is used to collect residual adhesive, adhesive remover, and water scraped off from the glue roller 10. Furthermore, the slag collection trough 3821 is connected to the drainage trough 3822. A drainage hole 3811 is provided on the tray body 381, located on the drainage trough 3822. In this way, residual adhesive will be blocked in the slag collection trough 3821 by the grid 382, ​​and the cleaned wastewater can flow through the grid 382 into the drainage trough 3822 and be discharged from the drainage hole 3811. This separates the residual adhesive and wastewater on the waste tray 38 for easy sorting and cleaning.

[0048] In one embodiment, the push cylinder 341 is pneumatically connected to the solenoid valve, and both the solenoid valve and the rotary motor 343 are electrically connected to the controller, for example, a PLC. By setting the number of cleaning cycles and the cleaning time on the controller, the controller drives the push cylinder 341 and the rotary motor 343 to work, thereby causing the cleaning plate 31 to drive the scraper 32 and the cleaning cotton 33 to clean the top glue roller 10. In this way, the automatic cleaning device 1 for the laminating machine of this application can automatically clean the top glue roller 10, thereby improving production quality and production efficiency.

[0049] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
