[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0055] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0056] like Figures 1 to 3 As shown, at least one embodiment provides a reciprocating wiping device for a coating roller, comprising: a wiping workbench 1; and a wiping mechanism 2 and a roller mounting mechanism 3 arranged on the wiping workbench 1; and a wiping sponge replacing mechanism arranged on the wiping workbench 1; wherein a plurality of coating roller mounting positions are provided on the roller mounting mechanism 3, the wiping mechanism 2 is located below the roller mounting mechanism 3, and wipes the surface of the coating roller by reciprocating left and right movement; and the wiping sponge replacing mechanism is provided on the horizontal frame of the wiping workbench 1 to replace the wiping sponge 242 when the wiping mechanism 2 moves back and forth.

[0057] Specifically, the reciprocating wiping device for the coating roller comprises a wiping mechanism 2 and a roller mounting mechanism 3, both mounted on a wiping workbench 1, and a wiping sponge replacement mechanism, mounted on the wiping workbench 1. This mechanism works in conjunction with each other to wipe the surface of the coating roller during the reciprocating motion of the wiping mechanism 2. Furthermore, the wiping sponge replacement mechanism, mounted on the horizontal frame of the wiping workbench 1, replaces the wiping sponge 242 as the wiping mechanism 2 moves back and forth. This allows for automatic replacement of the wiping sponge 242, and a distance detection sensor ensures precise alignment of the wiping sponge 242, improving the installation accuracy of the wiping sponge 242.

[0058] Specifically, the wiping mechanism 2 includes a mounting bracket 21 and a wiping sponge assembly 24. The wiping mechanism 2 is pushed closer to or away from the coating roller by the driving cylinder 22. The wiping sponge assembly 24 also includes a sponge fixing frame 241 and a wiping sponge 242. The sponge fixing frame 241 and the wiping sponge 242 are clipped together. When the coating roller needs to be wiped, the driving cylinder 22 pushes the sponge fixing frame 241 to move upward until the upper surface of the wiping sponge 242 abuts against the lower surface of the coating roller, and then drives the wiping sponge 242 to move left and right through the guide rail slide module 23, thereby realizing the wiping of the coating roller.

[0059] Specifically, the guide rail slide module 23 includes: a drive motor 232 and a guide rail 231, and the sponge fixing frame 241 is arranged on the guide rail 231. The drive motor 232 drives the guide rail 231 to move back and forth left and right. As an optional embodiment, the cooperation between the drive motor 232 and the guide rail 231 can be selected as a motor and a screw rod, so that the sponge fixing frame 241 moves along the F2 direction under the rotation of the drive motor 232, and in order to realize the left and right reciprocating movement of the sponge fixing frame 241, the drive motor 232 can be selected as a servo motor.

[0060] like Figure 4 As shown, specifically, the wiping sponge replacement mechanism includes: a sponge placement plate 4, a wiping sponge storage position 41 is horizontally opened on the sponge placement plate 4; the mounting bracket 21 is slidably arranged on the translation slide rail 5 of the horizontal frame; and a pushing cylinder (not shown in the figure) is provided on the translation slide rail 5, the fixed end of the pushing cylinder is connected to the translation slide rail 5, and its telescopic end is connected to the mounting bracket 21. When the wiping sponge 242 needs to be replaced, the pushing cylinder pushes the mounting bracket 21 along the F1 direction close to the sponge placement plate 4. Since the sponge fixing frame 241 corresponds to the position of the wiping sponge storage position 41, the wiping sponge 242 pre-stored on the wiping sponge storage position 41 can slide into the sponge fixing frame 241, squeezing out the original wiping sponge 242, and by accurately controlling the pushing depth of the pushing cylinder, the wiping sponge 242 in the wiping sponge storage position 41 can completely slide into the sponge fixing frame 241, thereby realizing accurate positioning and replacement of the wiping sponge 242.

[0061] As an optional embodiment, since the material of the wiping sponge 242 is relatively soft, in order to achieve complete sliding in, a fixing plate can be attached to the bottom of the wiping sponge 242, and the wiping sponge 242 can be accurately replaced through the hard contact of the two fixing plates.

[0062] Specifically, the roller mounting mechanism 3 includes: a coating roller rack 32 and a servo motor 31; wherein the coating roller rack 32 is mounted on the horizontal frame of the wiping workbench 1; the servo motor 31 is arranged on one side of the coating roller rack 32; and a transmission shaft 33 is provided on the coating roller rack 32; one end of the transmission shaft 33 is connected to the servo motor 31, and the other end is connected to the coating roller, so that the coating roller can rotate under the drive of the servo motor 31, thereby changing the wiping surface.

[0063] Specifically, the reciprocating wiping device further includes: a distance detection sensor, which is arranged on the sponge placement plate 4 to detect the distance between the sponge placement plate 4 and the sponge fixing frame 241 .

[0064] like Figure 5As shown, as an optional implementation, the distance detection sensor can adopt the photoelectric detection sensor in the existing technology, and the setting method can be configured as an embedded setting that does not affect the normal operation of each component; the control module selects a PLC control device, and controls the start and stop and movement direction of the corresponding drive source through the electrical connection between the control module and the distance detection sensor, and the corresponding distance data obtained by the distance detection sensor, so as to realize the surface wiping of the coating roller and the automatic replacement of the wiping sponge 242.

[0065] The specific working process of this device is as follows: the coating roller to be cleaned is installed on the coating roller placement rack 32, and then the driving cylinder 22 is started to push the wiping sponge 242 upward until it contacts the coating roller, and then the driving motor 232 is turned on to make the wiping sponge 242 move back and forth left and right. After working in this way for a specified number of times, the driving cylinder 22 is turned on again to make the wiping sponge 242 move downward away from the coating roller, and then the servo motor 31 is turned on to make the coating roller rotate a specified angle, and then the above process is repeated until the outer surface of the coating roller is completely wiped. If the wiping sponge 242 needs to be replaced, the pushing cylinder is turned on to make the sponge fixing rack 241 close to the sponge placement plate 4 until the new wiping sponge 242 is stuck in the sponge fixing rack 241, and then the cylinder is pushed back to the initial working position to prepare for the next cleaning.

[0066] In summary, the reciprocating wiping device for the coating roller utilizes a wiping mechanism 2 and a roller mounting mechanism 3, both mounted on a wiping workbench 1, and a wiping sponge replacement mechanism, mounted on the wiping workbench 1, to cooperate with each other. This allows the coating roller surface to be wiped during the reciprocating movement of the wiping mechanism 2. Furthermore, the wiping sponge replacement mechanism, mounted on the horizontal frame of the wiping workbench 1, allows the wiping sponge 242 to be replaced as the wiping mechanism 2 moves back and forth. This allows for automatic replacement of the wiping sponge 242, and a distance detection sensor allows for precise alignment of the wiping sponge 242, improving the installation accuracy of the wiping sponge 242.

In addition to the orientations depicted in the figures, spatially relative terms may be intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as being "below" or "below" other elements or features will be oriented to be "above" the other elements or features. Thus, the example term "below" may encompass both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0076] In the above discussion, unless otherwise indicated, the terms "about," "approximately," "substantially," etc., when used to describe a numerical value, mean a variation of + / - 10% of the value.
