Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to an anti-splash device for aluminum foil. Background Technology

[0002] During the operation of a coating machine, the rotating roller transfers the coating liquid onto the material to be coated. However, due to the high-speed rotation of the roller and the viscosity and fluidity of the coating liquid, it easily splashes off the roller surface. This splashing not only wastes the coating liquid and increases production costs, but the splashed coating liquid may also contaminate other parts of the coating machine, affecting the normal operation and service life of the equipment. Furthermore, if the splashed coating liquid comes into contact with operators, it may pose a certain health hazard.

[0003] In order to control the amount of coating liquid used, coating machines on the market generally adopt a scraper structure that is in contact with the printing roller, intending to scrape off excess coating. However, in reality, the outer diameter of the two shaft ends of the printing roller is smaller than the outer diameter of the roller body. This causes the excess coating scraped off by the scraper to overflow along the roller body to both ends of the printing roller. Due to the structural limitations, the scraper cannot make effective contact with the two shaft ends of the printing roller, making the two ends of the printing roller the main areas of coating liquid splashing.

[0004] However, the existing working process described above is prone to equipment contamination and safety issues caused by coating liquid splashing. Utility Model Content

[0013] Preferably, the groove has a V-shaped structure.

[0014] Preferably, the bushing includes a first baffle, a second baffle fixed around the outer periphery of the first baffle, a cylindrical sleeve extending from the side of the second baffle away from the roller body, and a shaft hole formed through the sleeve and the first baffle; the splash guard is fixed to the second baffle by a plurality of positioning buckles; the roller shaft is disposed in the shaft hole and forms a rotatable connection; the end of the sleeve away from the roller body is fixed to the frame.

[0015] Preferably, the thickness of the first baffle is greater than the thickness of the second baffle, and the side of the first baffle closest to the roller body is flush with the side of the second baffle closest to the roller body; the outer diameter of the second baffle is the same as the outer diameter of the roller body.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 As shown, this embodiment of the present invention provides an anti-splash device 100, applied to a coating machine roller, including a frame 1, a gravure roller 3 mounted on the frame 1 and rotatably connected to the frame 1, two bushings 7 rotatably disposed at opposite ends of the gravure roller 3, and anti-splash plates 8 respectively fixed to the two bushings 7; the gravure roller 3 includes a roller body 31 and roller shafts 32 fixed at opposite ends of the roller body 31, the bushings 7 are sleeved on the roller shafts 32, the roller shafts 32 are rotatably connected to the frame 1, and the bushings 7 are spaced apart from the frame 1. The frame 1 is used to mount the gravure roller 3 and the bushings 7.

[0032] The splash guard 8 includes a first arc-shaped plate portion 81 detachably fixed to the side of the bushing 7 away from the roller body 31 and disposed perpendicular to the axis of the bushing 7, a second arc-shaped plate portion 82 extending from the outer periphery of the first arc-shaped plate portion 81 toward the roller body 31, and an arc-shaped slot 84 recessed from the second arc-shaped plate portion 82 toward the side away from the first arc-shaped plate portion 81; the outer periphery of the roller body 31 and the second arc-shaped plate portion 82 are spaced apart from the roller body 31, and the projection of the second arc-shaped plate portion 82 onto the roller body 31 along the axis perpendicular to the roller shaft 32 falls on the roller body 31; the first arc-shaped plate portion 81 is spaced apart from the frame 1, and the arc-shaped slot 84 penetrates the second arc-shaped plate portion 82 circumferentially.

[0033] Specifically, by setting up the splash guard 8, especially the second arc-shaped plate 82, the waste of coating liquid is effectively reduced. The slot can be inserted with a flexible material baffle to increase the extension length of the second arc-shaped plate 82, further expanding the splash protection range and reducing the situation where the coating liquid splashes everywhere at the roller 32.

[0034] In this embodiment, the axis of the splash guard 8 coincides with the axis of the gravure roller 3, and the inner diameter of the second arc-shaped plate portion 82 is larger than the outer diameter of the roller body 31. This facilitates the matching of the inner diameter of the second arc-shaped plate portion 82 with the outer diameter of the roller body 31. This matching design enhances the protective effect of the splash guard 8 on the roller shaft 32 and improves the reliability of the anti-splash device 100.

[0035] In this embodiment, the opening of the arc-shaped slot 84 is located above the roller body 31. Preferably, the opening of the arc-shaped slot 84 is located above the roller body 31, and the width of the arc-shaped slot 84 is 2cm, and the depth of the arc-shaped slot 84 is 6cm.

[0036] In this embodiment, the splash guard 8 further includes a plurality of positioning holes 83 formed through the first arc-shaped plate portion 81 along its axial direction, and the plurality of positioning holes 83 are spaced apart from each other; the bushing 7 is provided with a plurality of positioning buckles 9 that cooperate with the positioning holes 83 for fixing the splash guard 8 to the bushing, and the plurality of positioning buckles 9 are respectively engaged in the plurality of positioning holes 83.

[0037] Specifically, during installation, the splash guard 8 is fixed to the bushing 7 by aligning the positioning holes 83 with the positioning clips 9. Disassembly is performed in reverse order, securing the bushing 7 and ensuring a more stable positioning process. Multiple positioning holes 83 guarantee the secure and accurate installation of the splash guard 8. The design of multiple positioning holes 83 and positioning clips 9 facilitates the installation and disassembly of the splash guard 8, making it easier to perform cleaning, replacement, and other maintenance operations, thus improving the maintainability of the equipment.

[0038] In this embodiment, the positioning buckle 9 includes an elastic connecting portion 91 fixed to the side of the bushing 7 near the first arc-shaped plate portion 81, two limiting bosses 93 protruding from opposite sides of the connecting portion 91 along the radial direction of the roller body 31, and a groove 92 formed by the recess of the connecting portion 91 away from the roller body 31 and sandwiched between the two limiting bosses 93; the connecting portion 91 passes through the corresponding positioning hole 83 and causes the limiting bosses 93 to abut against the side of the first arc-shaped plate portion 81 away from the roller body 31.

[0039] Optionally, the bottom surface of the limiting boss 93 abuts against the outer surface of the first arc-shaped plate portion 81, so that the first arc-shaped plate portion 81 is detachably fixed to the bushing 7.

[0040] In this embodiment, the groove 92 has a V-shaped structure.

[0041] Specifically, after the elastic connecting part 91 of the positioning buckle 9 is inserted into the positioning hole 83, the V-shaped groove 92 causes the connecting part 91 to deform within the positioning hole 83, thereby providing friction and preventing the positioning buckle 9 from coming out of the positioning hole 83. The bottom surface of the limiting boss 93 presses against the outer surface of the first arc-shaped plate part 81, further enhancing the fixing effect. The fixing characteristic of the bushing 7 ensures that the positioning buckle 9 is not disturbed by the rotation of the bushing 7 during the fixing process, resulting in greater stability. This structural design of the positioning buckle 9 improves the stability of the splash guard 8 fixed on the bushing 7, ensuring that the splash guard 8 will not loosen or fall off during the high-speed rotation of the gravure roller 3, continuously and effectively performing its anti-splash function and meeting the requirements for the stability of the anti-splash structure.

[0042] In this embodiment, the bushing 7 includes a first baffle 73, a second baffle 72 fixed around the outer periphery of the first baffle 73, a cylindrical sleeve 71 protruding from the side of the second baffle 72 away from the roller body 31, and a shaft hole 74 forming through the sleeve 71 and the first baffle 73; the splash guard 8 is fixed to the second baffle 72 by a plurality of positioning buckles 9; the roller shaft 32 is disposed in the shaft hole 74 and forms a rotatable connection; the end of the sleeve 71 away from the roller body 31 is fixed to the frame 1. The side of the first baffle 73 closest to the gravure roller 3 is in contact with the end face of the gravure roller 3.

[0043] Specifically, the bushing 7 is fixed to the frame. When the gravure roller 3 rotates, the bushing 7 remains stationary. The second baffle 72 protects the connection between the roller shaft 32 and the frame 1, preventing coating liquid from leaking from this point. Simultaneously, it provides a stable mounting base for the splash guard 8, ensuring that the splash guard 8 can stably perform its splash-proof function after being fixed to the bushing 7. The structural design of the bushing 7 enhances the protection at the connection between the roller shaft 32 and the frame 1, ensures the stability of the splash guard 8 installation, and improves the overall splash-proof performance of the equipment.

[0044] In this embodiment, the outer diameter of the second baffle 72 is the same as the outer diameter of the roller 31.

[0045] Specifically, the first baffle 73 prevents the coating liquid from leaking from the gap between the end face of the gravure roller 3 and the bushing 7, and works in conjunction with the second baffle 72 to strengthen the protection of the end of the roller shaft 32. Even if coating liquid overflows to the end of the roller shaft 32, it can be effectively blocked, reducing the possibility of outward splashing. The first baffle 73 also allows the splash guard 8 to prevent the coating liquid from flowing back into the material tank 5 from the gap for recycling.

[0046] In this embodiment, the anti-splash device 100 further includes a pressure roller 2, which is mounted on the frame 1 and forms a rotatable connection; the pressure roller 2 is disposed directly above the gravure roller 3, and the pressure roller 2 and the gravure roller 3 are spaced apart from each other.

[0047] In this embodiment, the anti-splash device 100 further includes a material trough 5, a feeding roller 4 disposed in the material trough 5, and a scraper 6. The material trough 5 is fixed to the frame 1, the feeding roller 4 is located below the gravure roller 3, and the scraper 6 is fixed to the frame 1 and located on one side of the gravure roller 3. Both the feeding roller 4 and the scraper 6 are in contact with the outer peripheral side of the gravure roller 3.

[0048] Specifically, a pressure roller 2 is also provided on the frame 1. The pressure roller 2 is located directly above the gravure roller 3, and there is a gap between the pressure roller 2 and the gravure roller 3. A feed roller 4, a material trough 5, and a scraper 6 are also installed on the frame 1. The feed roller 4 and the scraper 6 are both in contact with the outer wall of the gravure roller 3, and the material trough 5 is located below the feed roller 4 and the scraper 6.

[0049] Specifically, the pressure roller 2 on the frame 1 is located directly above the gravure roller 3. During the coating process, the pressure roller 2 squeezes the coating material, making the coating liquid more evenly distributed on the material surface. The feed roller 4 is in contact with the outer wall of the gravure roller 3, picks up the coating liquid from the feed trough 5 and transfers it onto the gravure roller 3. The doctor blade 6 is in contact with the outer wall of the gravure roller 3 and scrapes off the excess coating liquid on the gravure roller 3. Throughout the process, the anti-splash structure, through components such as the bushing 7 and the anti-splash plate 8, continuously prevents the coating liquid from splashing when the roller rotates. All components work together to achieve the coating operation.

[0050] Specifically, during the operation of the coating machine, the gravure roller 3 rotates, and the roller shaft 32 rotates within the bushing 7 fixed to the frame 1. The splash guard 8 is detachably fixed to the bushing 7 via a first arc-shaped plate portion 81. The second arc-shaped plate portion 82 extends axially along the side of the first arc-shaped plate portion 81 near the roller body 31, covering the upper part of the roller shaft 32. When coating liquid overflows to the roller shaft 32, the second arc-shaped plate portion 82 prevents it from splashing outwards. Simultaneously, a flexible baffle can be inserted into the arc-shaped slot 84, increasing the extension length of the second arc-shaped plate portion 82 and further expanding the splash-proof range, reducing the likelihood of coating liquid splashing everywhere at the roller shaft 32. By setting up the splash guard 8, especially the second arc-shaped plate portion 82, coating liquid waste is effectively reduced, and the risk of contamination to other parts of the equipment is minimized.

[0051] The working principle of this utility model is as follows:

[0052] During the operation of the coating machine, the gravure roller 3 rotates, and its roller shaft 32 rotates within the bushing 7. The bushing 7 is fixed to the side wall of the frame 1 by the sleeve body 71, maintaining a stationary state. The splash guard 8 installed on the bushing 7 is connected to the positioning buckle 9 on the bushing 7 through the positioning hole 83 on the first arc-shaped plate part 81, achieving a stable and detachable connection. The second arc-shaped plate part 82 of the splash guard 8 covers the upper part of the roller shaft 32, and its inner diameter is adapted to the outer diameter of the roller body 31, closely close to the roller body 31, initially forming a protective barrier at the roller shaft 32.

[0053] When the coating liquid overflows from the roller body 31 to the roller shaft 32 because the outer diameter of the two shaft ends of the printing roller is smaller than that of the roller body 31, the second arc-shaped plate portion 82 blocks most of the coating liquid from splashing to the outside of the roller shaft 32. The slot plays a key role at this time, and a flexible baffle can be inserted. These flexible baffles extend the length of the second arc-shaped plate portion 82 without affecting the rotation of the gravure roller 3, thereby further expanding the protection range. The outer diameter of the second baffle 72 on the bushing 7 is the same as that of the roller body 31, which protects the connection between the roller shaft 32 and the frame 1 and reduces the leakage of coating liquid from this part. The small baffle fits against the end face of the gravure roller 3, which allows the splash guard 8 to prevent the coating liquid from flowing back into the material tank 5 for recycling from the gap. During the coating operation, the pressure roller 2, the feed roller 4, the material trough 5, and the doctor blade 6 work together to transfer and coat the coating liquid. The entire anti-splash device 100 continuously plays an anti-splash role as the printing roller rotates, relying on components such as the anti-splash plate 8 fixed on the bushing 7.

Those skilled in the art should understand that any modifications or equivalent substitutions made to the present invention without departing from its spirit and scope should be covered within the scope of the present invention.
