Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, and more specifically, to a coating roller cleaning device and a roller press. Background Technology

[0002] In coating equipment, whether gravure, transfer, or extrusion coating, the coating rollers come into direct or indirect contact with the slurry, so they all require cleaning. This is especially true for extrusion coating, where the coating roller surface must not be contaminated during the coating process, otherwise the coating quality will be affected. Therefore, extrusion coating requires a fully automatic online cleaning device to clean the coating rollers while they are in normal coating operation. In extrusion coating, the foil passes between the coating roller and the extrusion head. To provide sufficient coating space for the extrusion head lip and to prevent the foil from slipping on the coating roller, the wrap angle of the coating roller is relatively large, generally between 170° and 220°. This means that the automatic cleaning device can only be installed on the opposite side of the extrusion head, and the installation space is limited.

[0003] Most current automatic steel roller cleaning devices only have one rubber roller for cleaning, resulting in insufficient contact between the wiping cloth and the coating roller, making it impossible to form a wrapping angle and leading to poor wiping effect. Some automatic steel roller cleaning devices, although equipped with two rubber rollers for cleaning the steel roller, cause the material roll to deform because the unwinding of the automatic steel roller cleaning device directly presses on the coating steel roller. This causes the friction between the cloth and the coating steel roller to vary, affecting the wiping effect. Utility Model Content

[0004] The main purpose of this invention is to provide a coating roller cleaning device and a roller press to solve the problem of poor cleaning effect of coating rollers in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a coating roller cleaning device is provided, comprising a base, a wiping roller assembly, and an adjusting member. The wiping roller assembly is rotatably connected to the base, and the wiping roller assembly has at least two wiping ends. A gap is provided between the wiping ends and the coating roller to be wiped for the wiping cloth to pass through. When the wiping ends abut against the coating roller, the wiping cloth cleans the coating roller. The adjusting member is movably disposed with respect to the base and abuts against the wiping roller assembly. The adjusting member pushes the wiping roller assembly to rotate relative to the base so that all wiping ends abut against the coating roller.

[0006] Furthermore, the adjusting component includes a movable adjusting rod, the wiping roller assembly has an adjusting surface, the adjusting rod abuts against the adjusting surface, and pushes the wiping roller assembly to rotate relative to the base.

[0007] Furthermore, the adjusting component also includes an adjusting nut, which is connected to the base body. The adjusting rod has a threaded structure, and the adjusting nut and the adjusting rod are threaded together. When the adjusting rod rotates, it drives the wiping roller assembly to rotate.

[0008] Furthermore, there are multiple adjusting components, including a first adjusting rod and a second adjusting rod that are movably disposed, and multiple adjusting surfaces, including a first adjusting surface and a second adjusting surface located on opposite sides of the wiping roller assembly. The first adjusting rod and the second adjusting rod abut against the first adjusting surface and the second adjusting surface, respectively. The wiping roller assembly rotates in opposite directions when the first adjusting rod is pushed and when the second adjusting rod is pushed.

[0009] Furthermore, the wiping roller assembly includes a support and a wiping roller. The support is rotatably connected to the base and includes a first section and a second section that are bent and connected. The wiping roller is rotatably disposed at the ends of the first section and the second section that are far apart from each other, and the wiping roller is closer to the coating roller than the connection between the first section and the second section. The wiping roller has a wiping end.

[0010] Furthermore, the first segment and the second segment each have a first adjustment surface and a second adjustment surface on the side that is far apart from each other. There are multiple adjustment members, which abut against the first adjustment surface and the second adjustment surface respectively. The first adjustment surface and the second adjustment surface are both inclined relative to the moving direction of the adjustment members, and their inclination directions are opposite.

[0011] Furthermore, the coating roller cleaning device also includes a spraying element, the outlet end of which is located above the wiping roller assembly and at the gap. The spraying element sprays liquid onto the wiping cloth at the gap and wets the wiping cloth.

[0012] Furthermore, the coating roller cleaning device also includes a wiping roller drive, which is driven to connect with the wiping roller assembly and drives the wiping roller assembly to move toward or away from the coating roller.

[0013] Furthermore, the coating roller cleaning device also includes an unwinding assembly and a rewinding assembly. Both the unwinding assembly and the rewinding assembly are rotatably connected to the base. The wiping cloth passes sequentially through the unwinding assembly, the wiping roller assembly, and the rewinding assembly. The rotation direction of the unwinding assembly is the same as the rotation direction of the coating roller; or the rotation direction of the unwinding assembly is opposite to the rotation direction of the coating roller, and the rotational linear velocity of the unwinding assembly is less than the rotational linear velocity of the coating roller.

[0014] According to another aspect of the present invention, a roller press is provided, including the above-described coating roller cleaning device.

[0015] By applying the technical solution of this utility model, an adjusting component is provided that can abut against the wiping roller assembly, and the wiping roller assembly has multiple wiping ends. On the one hand, the adjusting component can adjust the rotation of the wiping roller assembly relative to the base, so that all multiple wiping ends can abut against the coating roller, thereby ensuring the effectiveness of multiple wiping ends and improving the cleaning effect of the wiping roller assembly on the coating roller. This avoids the situation where some wiping ends do not abut against the coating roller, resulting in poor cleaning effect. On the other hand, the setting of multiple wiping ends ensures that when the wiping roller assembly drives the wiping cloth to clean the coating roller, a certain wrap angle is formed between the wiping cloth and the coating roller, thereby improving the cleaning effect of the coating roller.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0026] To address the problem of poor cleaning effect of coating rollers in the prior art, this utility model provides a coating roller cleaning device and a roller press, wherein the roller press includes the coating roller cleaning device described below.

[0027] like Figures 1 to 4 The coating roller cleaning device shown includes a base 10, a wiping roller assembly 20, and an adjusting member 30. The wiping roller assembly 20 is rotatably connected to the base 10 and has at least two wiping ends. There is a gap between the wiping ends and the coating roller 90 to be wiped for a wiping cloth 80 to pass through. When the wiping ends abut against the coating roller 90, the wiping cloth 80 cleans the coating roller 90. The adjusting member 30 is movably disposed with the base 10 and abuts against the wiping roller assembly 20. The adjusting member 30 pushes the wiping roller assembly 20 to rotate relative to the base 10 so that all wiping ends abut against the coating roller 90.

[0028] In this embodiment, by setting the adjusting member 30 to abut against the wiping roller assembly 20 and setting the wiping roller assembly 20 to have multiple wiping ends, on the one hand, the adjusting member 30 can adjust the wiping roller assembly 20 to rotate relative to the base 10, so that all multiple wiping ends can abut against the coating roller 90, thereby ensuring the effectiveness of multiple wiping ends and improving the cleaning effect of the wiping roller assembly 20 on the coating roller 90, avoiding the situation where some wiping ends do not abut against the coating roller 90, resulting in poor cleaning effect. On the other hand, the setting of multiple wiping ends ensures that when the wiping roller assembly 20 drives the wiping cloth 80 to clean the coating roller 90, a certain wrap angle is formed between the wiping cloth 80 and the coating roller 90, thereby improving the cleaning effect of the coating roller 90.

[0029] In this embodiment, the adjusting member 30 includes a movably disposed adjusting rod 31, and the wiping roller assembly 20 has an adjusting surface 23. The adjusting rod 31 abuts against the adjusting surface 23 and pushes the wiping roller assembly 20 to rotate relative to the base 10. Specifically, in this embodiment, the adjusting rod 31 is configured as a column, and the end of the adjusting rod 31 is disposed opposite to the adjusting surface 23. That is, the moving direction of the adjusting rod 31 forms an angle with the adjusting surface 23, so that when the adjusting rod 31 moves axially relative to the base 10, the adjusting rod 31 can move closer to or away from the adjusting surface 23. When the adjusting rod 31 approaches the adjusting surface 23, the end of the adjusting rod 31 approaching the adjusting surface 23 abuts against the adjusting surface 23, thereby pushing the adjusting roller assembly to rotate relative to the base 10, thereby adjusting the angle of the wiping end relative to the coating roller 90, and thus maintaining a suitable friction between the wiping cloth 80 and the coating roller 90, thereby improving the cleaning effect of the coating roller 90. Of course, the connection between the adjusting rod 31 and the seat 10 is not limited to axial movement. The adjusting rod 31 and the seat 10 can also be rotatably connected. For example, the adjusting rod 31 can be connected to the seat 10 through a rotating shaft. When the adjusting rod 31 rotates, the end of the adjusting rod 31 abuts against the adjusting surface 23 and drives the wiping roller assembly 20 to adjust the angle relative to the coating roller 90.

[0030] like Figure 1 , Figure 2 As shown, in this embodiment, the adjusting component 30 further includes an adjusting nut 32, which is connected to the base 10. The adjusting rod 31 has a threaded structure, and the adjusting nut 32 and the adjusting rod 31 are threadedly engaged. When the adjusting rod 31 rotates, it pushes the wiping roller assembly 20 to rotate, thereby adjusting the angle between the wiping roller assembly 20 and the coating roller 90, thus improving the wiping effect of the coating roller 90. Specifically, in this embodiment, the adjusting rod 31 has an external thread. One end of the adjusting rod 31 abuts against the adjusting surface 23, and the other end is provided with a head slightly larger than the threaded hole of the adjusting nut 32 to limit the adjustment stroke of the adjusting rod 31 and prevent the adjusting rod 31 from dislodging from the threaded hole of the adjusting nut 32 when it moves closer to the adjusting surface 23. The external thread of the adjusting rod 31 engages with the internal thread of the adjusting nut 32 to realize the axial movement of the adjusting rod 31, thereby achieving abutment against the adjusting surface 23. Of course, the adjusting part 30 may not have the adjusting nut 32, or a threaded hole may be provided on the base 10 so that the adjusting rod 31 passes through the threaded hole, thereby realizing axial movement.

[0031] like Figure 2As shown, in this embodiment, there are multiple adjusting members 30, and multiple adjusting rods 31 including a first adjusting rod 31 and a second adjusting rod 31 that are movably disposed. There are multiple adjusting surfaces 23, including a first adjusting surface 23 and a second adjusting surface 23 located on opposite sides of the wiping roller assembly 20. The first adjusting rod 31 and the second adjusting rod 31 abut against the first adjusting surface 23 and the second adjusting surface 23, respectively. The wiping roller assembly 20 rotates in opposite directions when the first adjusting rod 31 is pushed and when the second adjusting rod 31 is pushed, so that the adjusting members 30 can not only adjust the angle of the wiping roller assembly 20 relative to the coating roller 90, but also fix the angle of the wiping roller assembly 20 relative to the coating roller 90 after adjustment. Specifically, this embodiment provides two adjusting members 30 and two adjusting surfaces 23. The first adjusting rod 31 can abut against the first adjusting surface 23 to push the wiping roller assembly 20 to rotate in a first direction; the second adjusting rod 31 can abut against the second adjusting surface 23 to push the wiping roller assembly 20 to rotate in a second direction. The first direction and the second direction are opposite. When adjusting the angle of the wiping roller assembly 20 relative to the coating roller 90, with the first adjusting rod 31 abutting against the first adjusting surface 23, and the second adjusting rod 31 abutting against the second adjusting surface 23, the wiping roller assembly 20 cannot rotate in either the first or second direction, thus fixing the angle of the wiping roller assembly 20 relative to the coating roller 90, allowing both wiping ends to evenly abut against the coating roller 90. When it is necessary to readjust the angle of the wiping roller assembly 20 relative to the coating roller 90, the first and second adjusting members 30 must first be rotated to release the abutment fixation between the adjusting members 30 and the wiping roller assembly 20. Then, the rotation direction of the wiping roller assembly 20 is adjusted according to the actual situation so that all wiping ends of the wiping roller assembly 20 can abut against the coating roller 90, thereby achieving effective cleaning of the coating roller 90.

[0032] In this embodiment, the wiping roller assembly 20 includes a bracket 21 and a wiping roller 22. The bracket 21 is rotatably connected to the base 10 and includes a first section 211 and a second section 212 that are bent and connected. The wiping roller 22 is rotatably disposed at the ends of the first section 211 and the second section 212 that are far apart from each other. The wiping roller 22 is closer to the coating roller 90 than the connection between the first section 211 and the second section 212. The wiping roller 22 has a wiping end. Specifically, in this embodiment, the bracket 21 is V-shaped, with the opening of the V facing the coating roller 90. This allows the wiping roller 22 at the end of the first segment 211 and the wiping roller 22 at the end of the second segment 212 to approach the coating roller 90, thus forming a certain wrap angle between the wiping cloth 80 and the coating roller 90. This increases the contact area between the wiping cloth 80 and the coating roller 90, thereby improving the cleaning effect of the coating roller 90. The bottom of the V-shape, which is the connection between the first segment 211 and the second segment 212, is away from the coating roller 90, facilitating the installation of an adjustment member 30 on this side. This allows the wiping roller assembly 20 to be rotatably configured to adjust the angle of the wiping roller assembly 20 relative to the coating roller 90. A rotating shaft is provided on the base 10, and a rotating hole is provided at the connection between the first segment 211 and the second segment 212. The rotating shaft passes through the rotating hole, enabling a rotatable connection between the bracket 21 and the base 10. Of course, a rotating shaft can also be provided at the connection between the first segment 211 and the second segment 212, with the shaft passing through the mounting hole of the base 10, thereby achieving a rotatable connection between the bracket 21 and the base 10. Optionally, to improve the stability of the connection between the bracket 21 and the wiping roller 22, multiple brackets 21 can be provided, arranged along the axial direction of the wiping roller 22, to support the wiping roller 22 and prevent the wiping roller 22 from tilting or bending, which would affect the wiping effect. In this embodiment, two brackets 21 are provided, respectively located at both ends of the wiping roller 22, and each bracket is provided with a first adjustment surface and a second adjustment surface.

[0033] In this embodiment, the first segment 211 and the second segment 212 have a first adjustment surface 23 and a second adjustment surface 23 respectively on the side away from each other. Multiple adjustment members 30 are provided, each abutting against the first adjustment surface 23 and the second adjustment surface 23. The first adjustment surface 23 and the second adjustment surface 23 are both inclined relative to the moving direction of the adjustment member 30, and their inclination directions are opposite, thereby enabling the wiping roller assembly 20 to rotate. Specifically, in this embodiment, the adjustment surface 23 is provided on the side of the bracket 21 facing away from the coating roller 90 to facilitate the placement of the adjustment members 30. The first adjustment surface 23 and the second adjustment surface 23 are set at an angle, and the first adjustment rod 31 and the second adjustment rod 31 are set parallel to each other. In this way, the end of the first adjustment rod 31 abuts against the first adjustment surface 23 and drives the first adjustment surface 23 to move in the first direction, thereby driving the wiping roller assembly 20 to rotate in the first direction. The end of the second adjustment rod 31 abuts against the second adjustment surface 23 and drives the second adjustment surface 23 to move in the second direction opposite to the first direction, thereby driving the wiping roller assembly 20 to rotate in the second direction. This locks the position of the wiping roller assembly 20 in two opposite directions, thereby ensuring that the wiping end can abut against the coating roller 90. This ensures that the wiping cloth 80 and the coating roller 90 maintain a large wrap angle and reasonable friction, thereby ensuring the cleaning effect of the coating roller 90.

[0034] In this embodiment, the coating roller cleaning device further includes a spray element 40. The outlet end of the spray element 40 is located above the wiping roller assembly 20 and at the gap. The spray element 40 sprays liquid onto the wiping cloth 80 at the gap, wetting the wiping cloth 80 and thus maintaining the moisture of the wiping cloth 80, improving the cleaning effect. The spray element 40 can be mounted on the base 10 and is rotatable relative to the base 10. When the wiping roller assembly 20 rotates, the outlet end of the spray element 40 can be adjusted by rotating the spray element 40, so that the outlet end of the spray element 40 can be kept facing the wiping cloth 80 to ensure the wiping cloth 80 is moistened. Optionally, multiple spray elements 40 can be provided and arranged along the axial direction of the wiping roller 22 to ensure the wetting effect of the wiping cloth 80. Of course, this embodiment is provided with multiple wiping rollers 22. Depending on the actual situation, the spray element 40 can also be placed between two wiping rollers 22, with the outlet end of the spray element 40 facing the wiping cloth 80. This allows both dry wiping of the coating roller 90 by the wiping cloth 80 and wet wiping of the coating roller 90 by the wiping cloth 80, thereby improving the cleaning efficiency of the coating roller 90. Optionally, the spray liquid sprayed by the spray element 40 can be water, alcohol, acetone, etc.

[0035] In this embodiment, the coating roller cleaning device further includes a wiping roller drive 50, which is drivenly connected to the wiping roller assembly 20 and drives the wiping roller assembly 20 to move closer to or away from the coating roller 90. This achieves automated control of the contact between the wiping cloth 80 and the coating roller, thereby reducing manual intervention, lowering operational risks, and improving cleaning accuracy and efficiency. Specifically, in this embodiment, the wiping roller drive 50 can drive the wiping roller assembly 20 to move closer to the coating roller 90 to achieve contact between the wiping roller assembly 20 and the coating roller 90, or drive the wiping roller assembly 20 away from the coating roller 90 to avoid situations such as changing the material roll. The wiping roller drive 50 and the adjusting component 30 are located on the same side of the wiping roller assembly 20, that is, on the side of the wiping roller assembly 20 away from the coating roller 90. The mounting position of the adjusting component 30 on the base 10 can be fixed with the mounting position of the wiping roller assembly 20, so that while the wiping roller drive 50 pushes the wiping roller drive 50 to move, the adjusting component 30 can move synchronously to maintain the contact between the adjusting component 30 and the adjusting surface 23. In this way, the coating roller 90 cleaning device can complete the fully automatic online wiping of the coating roller 90 for a long period of time without stopping the machine. The coating roller 90 can be wiped at any time during normal operation of the equipment. Optionally, the wiping roller drive 50 can be a three-axis cylinder with adjustable cylinder pressure, thereby adjusting the friction between the wiping cloth 80 and the coating roller 90.

[0036] In this embodiment, the coating roller cleaning device further includes an unwinding assembly 60 and a rewinding assembly 70. Both the unwinding assembly 60 and the rewinding assembly 70 are rotatably connected to the base 10. The wiping cloth 80 passes sequentially through the unwinding assembly 60, the wiping roller assembly 20, and the rewinding assembly 70. The rotation direction of the unwinding assembly 60 is the same as the rotation direction of the coating roller 90; or the rotation direction of the unwinding assembly 60 is opposite to the rotation direction of the coating roller 90, and the linear velocity of the unwinding assembly 60 is less than the linear velocity of the coating roller 90. This results in relative motion between the wiping cloth 80 and the coating roller 90, thereby ensuring effective cleaning of the wiping cloth 80. Specifically, as... Figure 3 As shown, considering space limitations, this embodiment employs an arrangement where the rotation direction of the unwinding assembly 60 is opposite to that of the coating roller 90. The unwinding assembly 60 and the winding assembly 70 are arranged vertically, with the unwinding assembly 60 positioned above the winding assembly 70, and the coating roller 90 positioned on the side of the wiping roller 22 furthest from the unwinding assembly 60. When the coating roller 90 and the wiping roller 22 come into contact, the foil material passing through the coating roller 90 is conveyed from bottom to top and passes around the coating roller 90 from the side furthest from the wiping roller 22, meaning the foil material... Figure 3The coating roller 90 is conveyed to the left side, while the wiping cloth 80 is conveyed from top to bottom from the side of the wiping roller 22 closest to the coating roller 90, that is, between the wiping roller 22 and the coating roller 90. In this way, the coating roller 90 rotates clockwise, and the unwinding assembly 60 rotates counterclockwise, which causes the wiping roller 22 to rotate counterclockwise. This causes the foil to rotate clockwise along the direction of the coating roller 90's rotation, and the direction of the friction force exerted by the wiping cloth 80 on the coating roller 90 is also clockwise. Therefore, the rotational linear speed of the coating roller 90 is set to be greater than the rotational linear speed of the unwinding assembly 60, so as to ensure the normal operation of the foil coating process and the relative movement between the coating roller 90 and the wiping cloth 80, so as to ensure the effective cleaning of the coating roller 90 by the wiping cloth 80.

[0037] like Figure 4 As shown, the positions of the winding assembly 70 and the unwinding assembly 60 can be interchanged. The spraying component 40 is positioned below the wiping cloth 80 and is still placed between the unwinding assembly 60 and the wiping roller 22. The rotation direction of the unwinding assembly 60 is set to be the same as the rotation direction of the coating roller 90. At this time, the conveying direction of the foil remains unchanged, and the wiping cloth 80 is conveyed from bottom to top. At the position where the coating roller 90 abuts against the wiping end, the rotation direction of the coating roller 90 is opposite to the rotation direction of the wiping cloth 80. There must be relative movement between the two, and the rotation speed of the coating roller 90 and the conveying speed of the wiping cloth 80 can be flexibly adjusted, so that the cleaning of the coating roller 90 can also be achieved.

[0038] The process of cleaning the coating roller 90 using the coating roller cleaning device in this embodiment is as follows: The wiping cloth 80 conveyed by the unwinding assembly 60 passes through two wiping rollers 22 in sequence and then enters the winding assembly 70. Under the drive of the wiping roller drive member 50, the wiping roller assembly 20 can move closer to or further away from the coating roller 90. The angle of the wiping roller assembly 20 relative to the coating roller 90 can be adjusted by the adjusting member 30, thereby ensuring that the two wiping rollers 22 make uniform contact with the coating roller 90. Between the unwinding assembly 60 and the coating roller 90 assembly, a spray member 40 is provided above the wiping rollers 22, which can wet the wiping cloth 80 before it contacts the coating roller 90, thereby making it easier to clean the slurry adhering to the surface of the coating roller 90. Due to space constraints, this embodiment adopts a layout in which the wiping cloth 80 and the coating roller 90 move in the same direction. The linear velocity of the wiping cloth 80 and the linear velocity of the coating roller 90 are not the same, thereby causing relative motion between the wiping cloth 80 and the coating roller 90. The winding assembly 70 and the unwinding assembly 60 adopt a simple top cone structure, which allows for easy replacement of the reel.

[0039] It should be noted that "multiple" in the above embodiments refers to at least two.

[0040] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0041] 1. To solve the problem of poor cleaning effect of coating rollers in existing technologies;

[0042] 2. By setting the adjusting component to abut against the wiping roller assembly, and setting the wiping roller assembly to have multiple wiping ends, the adjusting component can adjust the rotation of the wiping roller assembly relative to the base body, so that all multiple wiping ends can abut against the coating roller, thereby ensuring the effectiveness of multiple wiping ends, and thus improving the cleaning effect of the wiping roller assembly on the coating roller, avoiding the situation where some wiping ends do not abut against the coating roller, resulting in poor cleaning effect;

[0043] 3. The multiple wiping ends ensure that when the wiping roller assembly drives the wiping cloth to clean the coating roller, a certain wrap angle is formed between the wiping cloth and the coating roller, thereby improving the cleaning effect of the coating roller.
