Water-based coating machine roll cleaner blade device

Abstract

This utility model relates to the field of laminating machine technology and discloses a cleaning scraper device for a water-based laminating machine's rubber roller. It includes a mounting frame, a fixed frame fixedly connected to one side of the mounting frame, a rubber roller body rotatably connected inside the fixed frame, and a scraping assembly inside the mounting frame. The scraping assembly includes a fixed shell inside the mounting frame, a flat scraper fixedly connected to one side of the fixed shell, a flat scraper strip on one side of the flat scraper, and a stepper motor fixedly installed inside the fixed shell. When the rubber roller body rotates, the flat scraper strip close to its exterior scrapes off the flowing adhesive. Simultaneously, multiple arc scrapers move laterally back and forth. When the arc scraper strips are in close contact with the rubber roller body, they apply a lateral pushing force to the pre-curled protruding adhesive on the surface after treatment by the flat scraper strips, reducing its adhesion. Combined with continuous scraping by the flat scraper and hot spraying, this improves the wetting and softening of the adhesive, facilitating its scraping off. It also allows for easy adjustment of the pressure on the rubber roller.

Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, and in particular to a cleaning scraper device for rubber rollers of water-based laminating machines. Background Technology

[0002] A water-based laminating machine is a specialized piece of equipment that uses water-based environmentally friendly adhesives to laminate plastic films onto the surface of printed materials. It is widely used in industries such as packaging, printing, and advertising to improve the waterproofness, wear resistance, gloss, and aesthetics of products. Its core component, the water-based laminating machine's rubber roller, directly participates in the adhesive coating and film pressing process, playing a decisive role in the lamination quality.

[0003] A search revealed that Chinese patent CN204564615U discloses a waste glue removal device for a laminating machine's glue roller. This device addresses the issue that during laminating machine use, excess waste glue tends to stick to one end of the glue roller. Over time, this accumulation causes inconvenience. The scraper can remove the waste glue from one end of the rotating glue roller, and the waste glue falls into a glue collection box and is then discharged through a guide pipe, allowing for recycling.

[0004] While the above methods facilitate the cleaning of waste adhesive, existing technologies typically use a sheet scraper to remove excess adhesive from the outside of the rubber roller. However, some adhesive, if not cleaned promptly and left to stand, will pre-harden on the surface, forming a rubber film. Consequently, when the scraper is used to scrape the adhesive, the pre-hardened adhesive on the surface will be scraped off by the sheet scraper, causing the internal fluid adhesive to be squeezed out. The pre-hardened adhesive on the surface tends to adhere to the rubber roller, forming irregular protrusions on the outside of the roller. This makes it difficult for the scraper to remove the surface adhesive, reducing the cleaning quality of the rubber roller. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a water-based coating machine roller cleaning scraper device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water-based laminating machine rubber roller cleaning scraper device, including a mounting frame, a fixed frame fixedly connected to one side of the mounting frame, a rubber roller body rotatably connected inside the fixed frame, and a scraping component provided inside the mounting frame; The adhesive scraping assembly includes a fixed housing, which is disposed inside the mounting frame. A flat scraper is fixedly connected to one side of the fixed housing, and a flat scraper strip is provided on one side of the flat scraper. A stepper motor is fixedly installed inside the fixed housing.

[0007] As a further description of the above technical solution: The output end of the stepper motor is fixedly connected to a lead screw, and the lead screw is threaded with multiple moving blocks, which are slidably connected inside the fixed housing.

[0008] As a further description of the above technical solution: A connecting frame is fixedly connected to one side of the movable block, and an arc scraper is fixedly connected to one end of the connecting frame. An arc scraper strip is provided on one side of the arc scraper. Both the arc scraper strip and the flat scraper strip are made of silicone. An electric hot water tank is fixedly connected to the upper surface of the mounting frame. A water inlet pipe is connected through the upper surface of the electric hot water tank. A blocking cap is threaded to one end of the water inlet pipe.

[0009] As a further description of the above technical solution: A delivery pipe is connected through one side of the electric hot water tank, a water pump is installed through the middle of the delivery pipe, a spray pipe is connected through one end of the delivery pipe, the spray pipe is fixedly connected to the upper surface of the mounting frame, and multiple spray heads are connected through one side of the spray pipe.

[0010] As a further description of the above technical solution: An adjustment component is provided on one side of the mounting bracket. The adjustment component includes a threaded tube that is rotatably connected to one side of the mounting bracket. Two through holes are opened on one side of the mounting bracket. A fixing block is fixedly connected to the lower surface of the fixing shell.

[0011] As a further description of the above technical solution: A screw is fixedly connected to the middle of one side of the fixing block, and limit rods are fixedly connected to both ends of one side of the fixing block. The limit rods are slidably connected inside the through hole, and the screw is threadedly connected inside the threaded tube.

[0012] As a further description of the above technical solution: A gear ring is fixedly connected to the outside of the threaded tube, and a stepper motor is fixedly installed on one side of the mounting bracket. A gear is fixedly connected to the output end of the stepper motor, and the gear and the gear ring are meshed.

[0013] This utility model has the following beneficial effects: 1. This utility model, through the setting of the scraping component, utilizes a flat scraper strip closely attached to the outside of the rubber roller body while the rubber roller body rotates, to facilitate the scraping off of the adhesive flowing outside the rubber roller body. At the same time, when multiple arc scrapers move laterally back and forth, when the arc scraper strip is in close contact with the outside of the rubber roller body, a lateral thrust is applied to the surface of the pre-cured protruding adhesive passing through the flat scraper strip, which helps to shift the protruding adhesive from its original adhesion position and reduce the adhesion force of the protruding adhesive. Under the continuous scraping of the rubber roller body by the flat scraper, it helps to scrape off the adhesive. In addition, the hot spray spraying on the outside of the pre-cured adhesive helps to improve the wettability and softening of the adhesive, thereby facilitating the scraping off of the adhesive.

[0014] 2. By adjusting the components, this utility model utilizes the movement of the screw to indirectly push the arc scraper and flat scraper closer to the rubber roller body, thereby adjusting the pressure of the arc scraper and flat scraper on the rubber roller according to the pre-tightening force required during use, thus improving the adjustability and flexibility of the device.

[0019] As attached Figure 4 As shown, a lead screw 8 is fixedly connected to the output end of the stepper motor 7, which is used to drive multiple moving blocks 9 to produce lateral reciprocating movement.

[0020] As attached Figure 5 As shown, the lead screw 8 is externally threaded with multiple moving blocks 9, which are slidably connected inside the fixed shell 4. The fixed shell 4 limits the movement of the moving blocks 9. A connecting frame 10 is fixedly connected to one side of the moving block 9, and an arc scraper 11 is fixedly connected to one end of the connecting frame 10, which supports the arc scraper strip 12. An arc scraper strip 12 is provided on one side of the arc scraper 11, which fits against the arc surface of the rubber roller body 3. Both the arc scraper strip 12 and the flat scraper strip 6 are made of silicone, which facilitates the scraping of glue.

[0021] As attached Figure 3 As shown, an electric water tank 13 is fixedly connected to the upper surface of the mounting bracket 1. The electric water tank 13 is a small electric water tank with a heating tube inside. A water inlet pipe 14 is connected through the upper surface of the electric water tank 13. A stop cover 15 is threaded to one end of the water inlet pipe 14 for adding water. A delivery pipe 16 is connected through one side of the electric water tank 13. A water pump 27 is installed through the middle of the delivery pipe 16. The water pump 27 is a small water pump for delivering water. A spray pipe 17 is connected through one end of the delivery pipe 16. The spray pipe 17 is fixedly connected to the upper surface of the mounting bracket 1. Multiple spray heads 18 are connected through one side of the spray pipe 17 to facilitate spraying.

[0022] As attached Figure 6As shown, an adjustment component is provided on one side of the mounting bracket 1. The adjustment component includes a threaded tube 19, which is rotatably connected to one side of the mounting bracket 1 and is threaded to match the screw 22. Two through holes 20 are provided on one side of the mounting bracket 1, which are matched to the limit rod 23.

[0023] As attached Figure 7 As shown, a fixing block 21 is fixedly connected to the lower surface of the fixing shell 4, which facilitates the indirect driving of the flat scraper 5 and the arc scraper 11 to approach the rubber roller body 3. A screw 22 is fixedly connected to the middle of one side of the fixing block 21. Limiting rods 23 are fixedly connected to both ends of one side of the fixing block 21. The limiting rods 23 are slidably connected inside the through hole 20, which facilitates the limiting of the fixing block 21. The screw 22 is threadedly connected to the inside of the threaded tube 19. A gear ring 24 is fixedly connected to the outside of the threaded tube 19, which facilitates the rotation of the threaded tube 19 when the gear ring 24 rotates. A stepper motor 25 is fixedly installed on one side of the mounting bracket 1. A gear 26 is fixedly connected to the output end of the stepper motor 25. The gear 26 and the gear ring 24 are meshed, which facilitates the rotation of the gear ring 24.

[0024] Working principle: In use, first install the mounting bracket 1 onto one side of the fixed frame 2 with the rubber roller body 3, then place the glue receiving box at the bottom of the fixed frame 2. Then, control the start of the stepper motor 25, so that when its output end drives the gear 26 to rotate, it will drive the gear ring 24 to rotate under the meshing of the gear ring 24. The gear ring 24 will drive the threaded tube 19 to rotate, and then, under the connection with the screw 22, drive the screw 22 to move laterally, pushing the fixed block 21 closer to one side of the rubber roller body 3. At this time, the limit rod 23 will slide inside the through hole 20, and the fixed block 21 will indirectly drive the flat scraper 6 and the arc scraper 12 to stick to one side of the rubber roller body 3. Then, fill the electric hot water tank 13 with water, turn on the electric hot water tank 13 so that the water inside is heated to a warm state, first start the water pump 27 to generate a conveying force for the water flow, and send the water inside the electric hot water tank 13 through the conveying pipe 16 and the spray. The connection of pipe 17 utilizes spray head 18 to spray the outside of the rubber roller body 3. Then, the stepper motor 7 is turned on, causing its output end to drive the lead screw 8 to reciprocate. When the lead screw 8 rotates, it drives multiple moving blocks 9 to reciprocate laterally inside the fixed shell 4. This movement is then transmitted laterally through the connecting frame 10 and the arc scraper 11. When the rubber roller body 3 rotates clockwise, the external adhesive is first scraped off by the flat scraper 6 supported by the flat scraper 5. The adhesive that is not scraped off moves to the arc scraper 12 through the flat scraper 6. When the multiple arc scrapers 12 move laterally, they generate a lateral scraping force on the unscraped adhesive, causing the adhered adhesive to loosen. At the same time, the spray softens the adhesive on the outside of the rubber roller body 3, so that when the adhesive moves to the flat scraper 6 again, the flat scraper 6 scrapes off the loosened adhesive, thereby improving the cleaning quality of the adhesive on the outside of the rubber roller body 3.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
