Description

Technical Field

[0001] This utility model relates to the field of printing press equipment technology, and in particular to a metal coating anilox roller cleaning machine. Background Technology

[0002] In flexographic printing equipment, the anilox roller, as the core ink transfer component, has evenly distributed ink-receiving holes on its surface that perform the crucial functions of ink storage, ink distribution, and quantitative ink transfer. After each printing job, the roller surface must be thoroughly cleaned promptly to prevent residual ink from solidifying and accumulating within the ink-receiving holes. If cleaning is incomplete, the effective volume of the ink-receiving holes will gradually decrease, leading to a decline in the accuracy of ink release and ultimately affecting the color reproduction and image clarity of the printed materials.

[0003] The current mainstream anilox roller cleaning process uses a combination of "immersion + brushing": an excessive amount of cleaning agent is injected into the cleaning tank to completely submerge the anilox roller, and mechanical brushing is performed after the ink softens. The anilox roller is hoisted into the cleaning tank, which not only occupies a large amount of vertical space, but also makes it easy for it to collide with other parts of the roller due to the high hoisting height, thus damaging the anilox roller.

[0004] Therefore, there is an urgent need for an anilox roller cleaning machine that facilitates the entry and exit of the anilox roller into the cleaning water tank. Utility Model Content

[0005] To solve the above technical problems, this utility model provides a metal coating anilox roller cleaning machine to facilitate the entry and exit of the anilox roller into and out of the cleaning water tank.

[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] Example 1:

[0032] like Figures 1 to 4 As shown, this embodiment provides a metal coating anilox roller cleaning machine, including a cleaning frame, a cleaning tank 1, and a drive assembly; the cleaning frame includes two support plates 11 arranged sequentially in the horizontal direction, and multiple roller brush assemblies are arranged between the two support plates 11, forming a cleaning space between the multiple roller brush assemblies, and the anilox roller 15 is arranged in the cleaning space; multiple rolling elements are arranged on the circumferential edge of the support plates 11; along the horizontal direction, one end of the cleaning tank 1 is provided with an openable tank lid; when the cleaning frame is located inside the cleaning tank 1, the roller shaft 16 of the anilox roller 15 passes through the support plate 11 and is rotatably connected to the inner wall of the cleaning tank 1, and the rolling elements roll in contact with the inner wall of the cleaning tank 1 in the horizontal direction; the drive assembly is drivenly connected to the roller shaft 16.

[0033] By placing the anilox roller 15 within the cleaning space, and supporting and protecting it with the support plate 11 and multiple roller brush assemblies, damage to the anilox roller 15 due to collisions during hoisting is effectively avoided. Simultaneously, the cleaning frame can enter and exit from the horizontal opening of the cleaning tank 1, significantly reducing the hoisting height of the cleaning frame and minimizing the vertical space occupied by the cleaning machine. This facilitates the entry and exit of the anilox roller 15 from the cleaning tank 1 while reducing the risks associated with excessive hoisting height and simplifying operation. The drive assembly rotates the anilox roller 15, ensuring full contact between it and the surrounding multiple roller brush assemblies, thereby completing the washing of the anilox roller 15.

[0034] To achieve rotational support for the anilox roller 15 from the cleaning tub 1, a rotational support structure is provided on the side of the tub lid facing the cleaning tub 1; one end of the roller shaft 16 is detachably connected to the rotational support structure. More specifically, the rotational support structure includes a support platform 19, one side of which is connected to the tub lid, and the other side of which is provided with a first bearing, with one end of the roller shaft 16 connected to the first bearing. Furthermore, during the cleaning process, the anilox roller 15 rotates at a low speed, requiring only the first bearing to provide rotational support. Therefore, to facilitate the disassembly and installation of the anilox roller 15 and the first bearing, the inner diameter of the first bearing can be larger than the diameter of the roller shaft 16 of the anilox roller 15.

[0035] In a more specific embodiment, such as Figure 4As shown, a coupling 18 is provided between the drive assembly and the other end of the roller shaft 16. The end of the coupling 18 away from the roller shaft 16 is connected to the drive assembly. A guide hole is provided at the end of the coupling 18 facing the roller shaft 16, and a connecting hole is provided along the axial direction of the coupling 18. The connecting hole and the guide hole are coaxially arranged and communicate with each other. The guide hole is used to guide the end of the roller shaft 16 so that the roller shaft 16 can be smoothly inserted into the connecting hole, thereby keeping the anilox roller 15 and the coupling 18 coaxial, so that the drive assembly can drive the anilox roller 15 to rotate.

[0036] To facilitate the transmission connection between the anilox roller 15 and the coupling 18, a transmission groove is provided along the radial direction of the coupling 18, with the groove open on the side facing the roller shaft 16. A pin hole is provided radially on the other end of the roller shaft 16. When cleaning the anilox roller 15, a transmission pin 17 is placed in the pin hole, and the transmission pin 17 is inserted into the transmission groove to connect the roller shaft 16 and the coupling 18. After the cleaning frame with the anilox roller 15 is pushed into the cleaning tank 1, the roller shaft 16 is inserted into the coupling 18, and simultaneously, the transmission pin 17 is inserted into the transmission groove, completing the transmission connection between the drive assembly and the anilox roller 15, allowing the anilox roller 15 to rotate under the drive of the motor 3 in the drive assembly.

[0037] Furthermore, to facilitate the storage of the cleaning agent, a storage tank 9 is also included. The storage tank 9 is used to store the cleaning agent and is connected to the cleaning tank 1 via a piping assembly. The storage tank 9 and the cleaning tank 1 are located on the same bracket 10, with the cleaning tank 1 positioned above the storage tank 9.

[0038] The piping assembly includes a liquid pump 7, an inlet three-way valve 5, a connecting pipe 4, and an inlet pipe 8. The first port of the inlet three-way valve 5 is connected to the lower part of the storage tank 9 via the inlet pipe 8; the second port of the inlet three-way valve 5 is connected to the inlet end of the liquid pump 7; the outlet end of the liquid pump 7 is connected to the upper part of the cleaning tank 1 via the connecting pipe 4; and the third port of the inlet three-way valve 5 is connected to the lower part of the cleaning tank 1. Powered by the liquid pump 7, the cleaning agent in the storage tank 9 flows along the connecting pipe 4 through the liquid pump 7 and the inlet pipe 8 into the cleaning tank 1. After cleaning, the valve core position of the inlet three-way valve 5 is switched so that the third port of the inlet three-way valve 5 connects to the first port, allowing the cleaning agent in the cleaning tank 1 to automatically flow into the storage tank 9.

[0039] To accelerate the return of the cleaning agent to the storage tank 9, a return pipe 6 and an outlet three-way valve 2 are also included. The first port of the outlet three-way valve 2 is connected to the connecting pipe 4, the second port of the outlet three-way valve 2 is connected to the upper part of the cleaning tank 1, and the third port of the outlet three-way valve 2 is connected to the upper part of the storage tank 9 through the return pipe 6.

[0040] The third port of the inlet three-way valve 5 is connected to the inlet of the liquid pump 7, and the first port of the outlet three-way valve 2 is connected to the connecting pipe 4. Through the liquid pump 7, the cleaning agent flows out from the bottom of the cleaning tank 1, sequentially passing through the inlet three-way valve 5, the connecting pipe 4, the outlet three-way valve 2, and the return pipe 6 before flowing into the storage tank 9. During the return flow of the cleaning agent to the storage tank 9, the drive of the liquid pump 7 accelerates the return speed, achieving rapid recovery of the cleaning agent.

[0041] A through hole is provided in the middle of the support plate 11. The roller shaft 16 of the anilox roller 15 passes through the support plate 11 and is rotatably connected to the inner wall of the cleaning tub 1. The roller shaft 16 of the anilox roller 15 can rotate within the through hole. The diameter of the through hole is larger than the diameter of the roller shaft 16, so that when the anilox roller 15 rotates, the support plate 11 and the multiple roller brush assemblies will not rotate, allowing the anilox roller 15 to move relative to the roller brush assemblies to complete the washing of the anilox roller 15.

[0042] The rolling element includes a roller 12. The support plate 11 has multiple mounting grooves on its circumferential edge. The roller 12 is mounted in the mounting grooves via a wheel axle and the support plate 11. The rotation direction of the roller 12 is parallel to the axis of the anilox roller 15, which enables the cleaning frame to enter and exit the cleaning tank 1 in a horizontal direction. At the same time, it facilitates the connection and separation of the roller shaft 16 and the coupling 18.

[0043] The roller brush assembly includes a roller brush 13 and a brush rod 14. The roller brush 13 is disposed in the middle of the brush rod 14, and the end of the roller brush 13 is connected to the support plate 11. The length of the brush rod 14 can be selected according to the length of the anilox roller 15, and the diameter of the roller brush 13, or the diameter of the cleaning space, can be selected according to the diameter of the anilox roller 15.
