Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically to a coating machine feeding mechanism for coating processing. Background Technology

[0002] Coating machines are mainly used for surface coating processes of products such as films and papers made of polymer materials. The main function of a coating machine is to coat a roll of substrate with a layer of adhesive, coating or ink with a specific function, and then dry the substrate before winding it up.

[0003] Existing coating machines typically mount plastic film rolls onto a feeding roller during coating. When changing the plastic film roll, operators often need to first adjust the height of the feeding roller, then remove the old plastic film roll from the roller, and finally mount the new plastic film roll onto the roller and lift it back to its original position. This increases the difficulty of operation during the feeding process, and due to the excessive weight of the material, it poses certain safety hazards during operation. Furthermore, it results in low work efficiency and a waste of manpower and time.

[0004] As disclosed in Chinese Patent CN218088033U, a coating machine feeding mechanism for coating processing uses a cylinder to drive a sliding rod to rise and fall, which in turn drives a lifting column and gears to mesh, causing the rotating frame to rotate. This adjusts the height of the feeding roller to facilitate disassembly and installation by the operator. Simultaneously, under the elastic force of a limit spring, two sliding sleeves move closer together and, with the cooperation of a connecting sleeve, clamp the feeding roller, thus facilitating feeding and improving work efficiency and safety. By placing the feeding roller on an arc-shaped plate, when the rotating frame flips and the connecting sleeve is adjusted in height, the arc-shaped plate moves closer to the rotating frame, engaging the connecting sleeve with the connecting shaft, further facilitating the installation and disassembly of the feeding roller.

[0005] However, during use, the material rollers are exposed to the air, which makes it easy for the plastic film to accumulate a lot of dust, making it difficult to clean.

[0006] Therefore, we urgently need to provide a feeding mechanism for coating machines used in coating processes. Utility Model Content

[0026] Please see Figures 1-4 This utility model provides a technical solution: Example

[0027] A coating machine feeding mechanism for coating processing includes a worktable 1 and a support block 2. The support block 2 is fixedly installed at the front and rear ends of the top left side of the worktable 1. A connecting rod 3 is installed on the adjacent side of the support block 2. A dustproof device is provided on the top right side of the worktable 1.

[0028] The dustproof device includes a dustproof unit and an installation unit. The dustproof unit is located on the top right side of the workbench 1, and the installation unit is located inside the dustproof unit.

[0029] The dustproof unit includes a fixing plate 401, a bearing 402, a mounting box 403, a discharge port 404, and a rotating shaft 405. The fixing plate 401 is fixedly installed on the front and rear ends of the outer surface of the connecting rod 3. The bearing 402 is fixedly installed on the right end of the side adjacent to the two fixing plates 401. The mounting box 403 is fixedly installed on the outer surface of the two bearings 402. The discharge port 404 is fixedly installed on the right side of the mounting box 403. The rotating shaft 405 is fixedly installed on the inner ring of the bearing 402 and extends into the interior of the mounting box 403. The rotating shaft 405 can rotate on the inner ring of the bearing 402, so that the material roller 409 can rotate when feeding material. The rotating shaft 405 has a slot inside. The shape of the front and rear ends of the material roller 409 is the same as the shape of the slot, which facilitates the installation of the material roller 409 on the rotating shaft 405.

[0030] The mounting unit includes a connecting block 406, a guide rod 407, a trapezoidal block 408, a material roller 409, and a spring 410. The connecting block 406 is fixedly mounted on the top left and right ends of the rotating shaft 405. The guide rod 407 is installed inside the connecting block 406. The trapezoidal block 408 is fixedly mounted on one end of the guide rod 407. The material roller 409 is installed inside the mounting box 403. The spring 410 is fixedly mounted on the right side of the right connecting block 406. The right side of the spring 410 is fixedly connected to the guide rod 407 to prevent the guide rod 407 from detaching from the connecting block 406. At the same time, it allows the guide rod 407 to move left and right through the spring 410, which facilitates the installation and replacement of the material roller 409. Example

[0031] Based on Embodiment 1: An adjustment device is provided on the front of the connecting rod 3. The adjustment device includes a gear 501, a slide rail 502, a rack 503, an electric push rod 504, and a support plate 505. The gear 501 is fixedly installed on the front end of the outer surface of the connecting rod 3. The slide rail 502 is fixedly installed on the top of the workbench 1. The rack 503 is slidably connected to the outside of the slide rail 502. The gear 501 and the rack 503 mesh with each other. The rack 503 moves left and right, driving the gear 501 to rotate, thereby adjusting the height of the material roller 409. The support plate 505 is fixedly installed on the top of the workbench 1. The electric push rod 504 is fixedly installed on the top of the support plate 505. The output end of the electric push rod 504 is fixedly connected to one end of the rack 503. The electric push rod 504 pushes the rack 503 to move left and right along the slide rail 502.

[0032] In use, open the top cover of the mounting box 403, align the front and rear ends of the material roller 409 with the slots opened in the rotating shaft 405, press down on the material roller 409, and the material roller 409 contacts the inclined side of the trapezoidal block 408, pushing the trapezoidal block 408 to the right, causing the guide rod 407 to slide along the connecting block 406, thereby squeezing the spring 410. When the front and rear ends of the material roller 409 are fully inserted into the slots, the spring 410 returns to its original position, pushing the guide rod 407 to move the trapezoidal block 408 to the left, blocking the two ends of the material roller 409, thereby allowing the material roller 409 to advance. During installation, when the plastic film wrapped around the material roller 409 is used up, the top cover is opened, the guide rod 407 is pulled to move the trapezoidal block 408 to the right, and then the material roller 409 is pulled upward to disassemble the material roller 409. Finally, a new material roller 409 is installed. When the height of the material roller 409 needs to be adjusted, the electric push rod 504 pushes the rack 503 to move along the slide rail 502, which drives the gear 501 to rotate, thereby causing the fixing plate 401 to rotate the mounting box 403 to the appropriate position, thus completing the height adjustment of the material roller 409.
