Description

Technical Field

[0001] This utility model relates to the technical field of industrial equipment cleaning devices, and in particular to a cleaning device for coating and bonding rollers. Background Technology

[0002] Coating rollers are industrial rollers primarily used for uniformly coating substrates such as paper, plastic film, and metal plates. They are made of stainless steel, special aluminum alloys, or hard alloy ceramic powder, possessing wear-resistant and corrosion-resistant properties. Coating thicknesses of 0.25 mm or more are achieved through plasma spraying.

[0003] Currently, the industry mainly uses two methods for cleaning coating and bonding rollers: one is manual cleaning, where operators use solvent-soaked cleaning tools to directly wipe the roller surface during production breaks or machine operation; the other is simple mechanical cleaning, which uses a fixed scraper structure to mechanically scrape away residual glue, dust, and other impurities from the roller surface.

[0004] However, existing cleaning methods, particularly manual cleaning, are not only inefficient and difficult to meet the needs of continuous production, but also require operators to be in close contact with running machines. Furthermore, the uneven pressure and coverage of manual wiping cannot completely remove hardened adhesive residue, and improper operation may introduce new dust particles, leading to abnormalities such as spots and bumps on the product. Direct friction between a simple scraper and the roller surface can scratch the expensive mirror roller surface, shortening the roller's lifespan. Utility Model Content

[0005] The purpose of this invention is to provide a coating and bonding roller cleaning device to alleviate the technical problems of existing technologies that cannot remove hardened adhesive residue and scratch the roller surface.

[0006] The coating and bonding roller cleaning device provided by this utility model includes: a mirror roller, a fixed frame, an electric push rod, a cleaning fixture, Velcro, a cleaning component, and a liquid addition assembly; A fixed frame in the shape of an inverted L is arranged on one side of the mirror roller. An electric push rod is set at the end of the fixed frame near the mirror roller. The output end of the electric push rod is connected to the cleaning fixture through a robotic arm. The cleaning fixture is arranged directly above the mirror roller. The curvature of the cleaning fixture is the same as that of the mirror roller. Velcro is attached to the front and rear ends and the center of the cleaning fixture. The cleaning parts can be detached from the side of the cleaning fixture facing the mirror roller via the Velcro. The bottom surface of the cleaning fixture has several drainage holes evenly distributed. The cleaning fixture is connected to a liquid filling component, which is used to wet the cleaning fixture with liquid through the drainage holes.

[0007] Furthermore, EVA anti-collision strips are attached to the two opposite end faces of the cleaning fixture, and the length of the EVA anti-collision strips is consistent with the length of the end faces of the cleaning fixture.

[0008] Furthermore, the cleaning component is a fine lint-free cloth or a polymer sponge.

[0009] Furthermore, Velcro includes a hook side and a loop side; The hook side is attached to the surface of the cleaning tool, and the hooked bristles of the hook side are attached to the rough side, which is then attached to the cleaning part.

[0010] Furthermore, it also includes an infrared device, which includes an infrared transmitter and an infrared receiver; An infrared transmitter is installed on one side of the cleaning fixture, and an infrared receiver is installed on the support of the mirror roller. The extension line of the detection line between the infrared transmitter and the infrared receiver is perpendicular to the ground and is used to detect the contact gap between the cleaning fixture and the mirror roller.

[0011] Furthermore, the liquid filling assembly includes a liquid filling port, a liquid filling pipe, and a liquid filling pump; The liquid filling port is located on one side wall of the cleaning fixture. One end of the liquid filling pipe is connected to the liquid filling port, and the other end of the liquid filling pipe is connected to the water supply tank. A liquid filling pump is installed on the liquid filling pipe.

[0012] Furthermore, the diameter of each seepage hole is 0.5 mm to 1 mm.

[0013] Furthermore, the transverse length of the cleaning fixture is not less than the same as the transverse length of the mirror roller.

[0014] Beneficial effects: In this invention, the cleaning device for coating and bonding rollers uses a cleaning fixture whose curvature matches the mirror roller. An electric push rod, combined with a robotic arm, precisely controls the position and pressure of the cleaning fixture, ensuring a tight and uniform fit between the cleaning component and the mirror roller surface, thus avoiding incomplete cleaning. The liquid supply component provides liquid to the cleaning component through evenly distributed drainage holes at the bottom of the cleaning fixture, maintaining a moderately moist state. This enhances the dissolution and peeling ability of residual materials (adhesive, dust) on the roller surface, while avoiding scratches or corrosion caused by traditional dry wiping or localized over-wetting, protecting the precision and service life of the mirror roller.

[0015] At the same time, it significantly improves operational convenience and production efficiency. The cleaning parts are detachably connected to the cleaning fixture via Velcro, allowing for quick replacement of the cleaning parts without the need for special tools, greatly reducing downtime for maintenance; it also reduces the intensity of manual operation and lowers the risk of damage to the mirror roller due to improper control of cleaning force.

[0025] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] like Figures 1-3 As shown, the coating and bonding roller cleaning device provided by this utility model includes: a mirror roller 1, a fixing frame 2, an electric push rod 3, a cleaning fixture 4, a Velcro 5, a cleaning component 6, and a liquid adding assembly 7. A fixed frame 2 in the shape of an inverted L is arranged on one side of the mirror roller 1. An electric push rod 3 is provided at one end of the fixed frame 2 near the mirror roller 1. The output end of the electric push rod 3 is connected to the cleaning tool 4 through a mechanical arm. The cleaning tool 4 is arranged directly above the mirror roller 1. The curvature of the cleaning fixture 4 is the same as that of the mirror roller 1. Velcro 5 is attached to the front and rear ends and the center of the cleaning fixture 4. The cleaning component 6 is detachably attached to the side of the cleaning fixture 4 facing the mirror roller 1 via the Velcro 5. The bottom surface of the cleaning fixture 4 has several drainage holes 401 evenly distributed. The cleaning fixture 4 is connected to a liquid filling component 7, which is used to wet the cleaning component 6 with liquid from the drainage holes 401 through the liquid filling component 7.

[0027] Specifically, the mirror roller 1 is horizontally installed at a preset station on the coating machine. An inverted L-shaped mounting bracket 2 is fixedly mounted on the ground frame on one side of the roller. The horizontal section of the mounting bracket 2 extends directly above the mirror roller 1, and an electric push rod 3 is bolted to the end of the horizontal section near the mirror roller 1. The output end of the electric push rod 3 extends vertically downwards and is rigidly connected to the cleaning fixture 4 via an adjustable-angle robotic arm. This ensures that the cleaning fixture 4 is precisely suspended above the mirror roller 1, and the inner curvature of the cleaning fixture 4 perfectly matches the outer curvature of the mirror roller 1, ensuring a gap-free fit. After pressing, the mirror roller 1 completes cleaning with one full rotation. On the side of the cleaning fixture 4 facing the mirror roller 1, a long strip of high-strength Velcro 5 is attached to both ends (i.e., the radial length direction) and the center of its curved surface. The three Velcro 5 are symmetrically distributed. The cleaning component 6 is detachably fixed to the cleaning fixture 4 by the adhesive force of the Velcro 5, and the size of the cleaning component 6 completely covers the bottom curved surface of the cleaning fixture 4. The cleaning fixture 4 has a sealed liquid storage chamber inside, and its bottom surface has several drainage holes 401 of the same diameter evenly distributed along the curved surface. The drainage holes 401 penetrate to the contact surface of the cleaning component 6. The side of the cleaning fixture 4 is connected to the liquid filling assembly 7 through a conduit to realize the directional delivery of liquid.

[0028] The electric push rod 3 is connected to the cleaning fixture 4 via a robotic arm and is used to adjust the bonding pressure between the cleaning fixture 4 and the mirror roller 1. The Velcro 5 not only makes the cleaning part 6 fit more tightly with the cleaning fixture 4, preventing displacement caused by the rotation of the mirror roller 1 during cleaning, but also enables the quick disassembly and replacement of the cleaning part 6. The curvature of the cleaning fixture 4 and the evenly distributed drainage holes 401 allow the cleaning liquid delivered by the liquid supply component 7 to penetrate evenly into the cleaning part 6, ensuring that the cleaning part 6 is always in a moist state. This not only improves the cleaning effect on residual glue and dust on the roller surface, but also avoids the risk of scratching the mirror roller 1 by the dry cleaning part 6, replacing manual cleaning or cleaning with a fixed simple scraper.

[0029] In an embodiment of this utility model, EVA anti-collision strips 402 are attached to two opposite end faces of the cleaning fixture 4, and the length of the EVA anti-collision strips 402 is consistent with the length of the end faces of the cleaning fixture 4.

[0030] Cleaning component 6 is a fine lint-free cloth or a polymer sponge.

[0031] The Velcro 5 includes a hook side and a rough side; the hook side is attached to the surface of the cleaning tool 4, the hooked bristles of the hook side are attached to the rough side, and the rough side is attached to the cleaning part 6.

[0032] Specifically, the cleaning fixture 4 has an arc-shaped plate structure that perfectly matches the outer curvature of the mirror roller 1. On the two opposite end faces (i.e., in the transverse length direction) of the cleaning fixture 4, an EVA anti-collision strip 402 is attached with strong adhesive. The length of the EVA anti-collision strip 402 is exactly the same as the length of the corresponding end face of the cleaning fixture 4, the thickness is 3-5mm, and the outer edge of the anti-collision strip is flush with the edge of the end face of the cleaning fixture 4, without protrusion or depression, so as to avoid interference with the mirror roller 1 or other parts of the equipment. The Velcro 5 consists of a hook side and a napped side that fit together. The hook side of the Velcro 5 is evenly attached to a preset position on the arc-shaped cleaning surface of the cleaning fixture 4 facing the mirror roller 1 using solvent-resistant adhesive, with the hooks and bristles facing upwards towards the cleaning component 6. The napped side of the Velcro 5 is correspondingly attached to the back of the cleaning component 6 (i.e., the side where the cleaning component 6 is attached to the cleaning fixture 4) using the same type of solvent-resistant adhesive. The size of the napped side perfectly matches the hook side. When the cleaning component 6 is assembled, the hooks and bristles of the hook side can tightly engage with the fiber layer of the napped side, achieving detachable fixation between the cleaning component 6 and the cleaning fixture 4. The cleaning component 6 can be made of fine lint-free cloth or polymer sponge, depending on the actual cleaning requirements.

[0033] EVA anti-collision strip 402 effectively avoids the risk of rigid collisions during the cleaning process, preventing excessive downward mechanical pressure from damaging the roller surface. The separate hook and loop sides of Velcro 5 enhance the ease of replacing the cleaning component 6: the hook side is fixed to the cleaning fixture 4, eliminating the need for frequent disassembly and maintaining long-term adhesion and structural stability; the loop side is replaced simultaneously with the cleaning component 6, resulting in low cost and simple operation. Workers can remove the old cleaning component 6 and attach the new one by manually peeling off the hook and loop sides without the need for tools. The cleaning component 6 is made of fine lint-free cloth or polymer sponge. Fine lint-free cloth utilizes its delicate fibers and lint-free properties, preventing lint residue from affecting coating quality after cleaning, while polymer sponge leverages its strong absorbency and water retention. Combined with the seepage holes 401 of the cleaning fixture 4, it maintains moisture for a long time, improving the cleaning effect on stubborn adhesive residue. Both materials are soft, allowing them to adhere tightly to the roller surface while avoiding scratching the smooth surface of the mirror roller 1, thus balancing cleaning effectiveness and roller surface protection.

[0034] In an embodiment of this utility model, an infrared device 8 is also included. The infrared device 8 includes an infrared transmitter 801 and an infrared receiver 802. The infrared transmitter 801 is disposed on one side of the cleaning fixture 4, and the infrared receiver 802 is disposed on the support of the mirror roller 1. The extension line of the detection line between the infrared transmitter 801 and the infrared receiver 802 is perpendicular to the ground and is used to detect the contact gap between the cleaning component 6 and the mirror roller 1.

[0035] The liquid filling assembly 7 includes a liquid filling port 701, a liquid filling pipe 702, and a liquid filling pump 703. The liquid filling port 701 is located on one side wall of the cleaning fixture 4. One end of the liquid filling pipe 702 is connected to the liquid filling port 701, and the other end of the liquid filling pipe 702 is connected to the water supply tank. The liquid filling pipe 702 is equipped with a liquid filling pump 703.

[0036] The diameter of each seepage hole 401 is 0.5 mm to 1 mm.

[0037] The transverse length of the cleaning fixture 4 is not less than the same as the transverse length of the mirror roller 1.

[0038] Specifically, the cleaning fixture 4 is an arc-shaped plate structure adapted to the outer curvature of the mirror roller 1. Its lateral length (the extension length along the axial direction of the mirror roller 1) is not less than the lateral length of the mirror roller 1, ensuring that it can completely cover the roller surface area of ​​the mirror roller 1 during cleaning, without any cleaning dead corners. The infrared device 8 consists of an infrared transmitter 801 and an infrared receiver 802 that cooperate with each other. The infrared transmitter 801 is fixed to one side of the cleaning fixture 4 along the axial direction of the mirror roller 1 by bolts, and the emission direction is perpendicular to the bracket of the mirror roller 1. The infrared receiver 802 is installed on the brackets on both sides of the mirror roller 1 on the same side as the infrared transmitter 801, so that the extension line of the detection line between the two is perpendicular to the ground, and the contact gap between the cleaning component 6 and the mirror roller 1 is monitored in real time. The liquid filling assembly 7 includes a liquid filling port 701, a liquid filling pipe 702, and a liquid filling pump 703. The liquid filling port 701 is opened on the side wall of the cleaning fixture 4 away from the infrared transmitter 801 and is connected to the liquid storage chamber inside the cleaning fixture 4. The cleaning fixture 4 has a plurality of drainage holes 401 evenly distributed on the arc-shaped cleaning surface facing the mirror roller 1. Each drainage hole 401 has a diameter of 0.5mm to 1mm, preferably 0.5mm, and all of them penetrate through the arc-shaped wall of the cleaning fixture 4 to the contact surface of the cleaning component 6, so as to realize the penetration of the cleaning liquid in the storage cavity into the cleaning component 6.

[0039] The cleaning fixture 4 has a transverse length not less than that of the mirror roller 1, ensuring that the cleaning part 6 completely covers the roller surface of the mirror roller 1. This prevents the coating quality from being affected by uncleaned areas due to insufficient length. The detection line extension of the infrared device 8 is perpendicular to the ground, capturing the contact gap between the cleaning part 6 and the mirror roller 1. When the gap is too large (incomplete cleaning) or too small (damage to the roller surface), it can promptly provide feedback signals to adjust the pressure of the electric push rod 3, ensuring both cleaning effectiveness and roller surface safety. The 0.5mm to 1mm seepage holes 401 ensure that the cleaning liquid penetrates evenly and slowly into the cleaning part 6, keeping the cleaning part 6 constantly moist to improve the cleaning effect on stubborn stains, while also preventing excessive cleaning liquid from contaminating the equipment due to excessively large hole diameters.

[0040] Based on the above embodiments, the specific working process of the coating and bonding roller cleaning device provided by this utility model is as follows: The liquid filling assembly 7 delivers the cleaning liquid to the cleaning fixture 4 via the liquid filling pipe 702 and the liquid filling port 701 through the liquid filling pump 703. The cleaning liquid permeates evenly through the seepage hole 401 and wets the cleaning part 6 which has been fixed to the cleaning fixture 4 by the Velcro 5. The infrared device 8 is activated simultaneously, and the infrared transmitter 801 and the infrared receiver 802 calibrate the contact gap between the cleaning part 6 and the mirror roller 1.

[0041] The electric push rod 3 pushes the cleaning fixture 4 downwards, and the cleaning component 6 on the cleaning fixture 4 fits tightly against the roller surface; as the mirror roller 1 rotates, the moistened cleaning component 6 simultaneously wipes away residual glue and dust from the roller surface. After cleaning is completed, the electric push rod 3 drives the cleaning fixture 4 to lift away from the mirror roller 1, and the liquid supply component 7 stops supplying liquid; if the cleaning component 6 is dirty, the Velcro 5 can be directly peeled off for quick replacement.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
