[0001] This utility model relates to the field of die-cutting technology, and in particular to a cleaning device and a die-cutting equipment having the same. Background Technology

[0002] In the die-cutting industry, circular cutters are used in processes such as lamination and pressing. During operation, impurities easily accumulate on the surface of the circular cutter, leading to decreased production efficiency, reduced product quality, and equipment wear. Cleaning rollers, which abut against the circular cutter, are typically used to clean it. However, in existing technologies, on the one hand, gaps can form between the cleaning roller and the circular cutter due to changes in the working environment, preventing a tight fit and reducing the cleaning efficiency. On the other hand, the adhesion between the cleaning roller and the circular cutter cannot be adjusted, making it unsuitable for specific needs. Utility Model Content

[0031] Please see Figures 1 to 4 , Figure 1 This is a three-dimensional structural schematic diagram of the cleaning device 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 A disassembly diagram of a portion of the structure of the cleaning device 100; Figure 3 yes Figure 1 A schematic diagram of the cleaning device 100 and the circular blade 200 mounted on the base 300; Figure 4 yes Figure 3A schematic diagram of the cleaning device 100 and the circular blade 200 mounted on the base 300 from another perspective. This embodiment of the invention provides a cleaning device 100, which includes a cleaning component 10, an adjusting component 20, and an elastic member 30. The cleaning assembly 10 includes a cleaning roller 12 and a mounting block 13. The cleaning roller 12 is rotatably connected to the mounting block 13. The mounting block 13 is provided with a first connecting part 11. The cleaning roller 12 is used to abut against the circular blade 200 so that it can be driven to rotate by the circular blade 200. The adjusting assembly 20 is rotatably connected to the base 300 on which the circular blade 200 is mounted. The adjusting assembly 20 is provided with a second connecting part 23. The adjusting assembly 20 is rotatably connected to the mounting block 13 and can rotate relative to the mounting block 13 to change the distance between the first connecting part 11 and the second connecting part 23. The elastic member 30 connects the first connecting part 11 and the second connecting part 23 and is in a stretched state. The elastic member 30 is used to apply an elastic force to the first connecting part 11 so that the mounting block 13 drives the cleaning roller 12 to press against the circular blade 200.

[0032] Specifically, the first connecting part 11 is a hole formed in the mounting block 13, the second connecting part 23 is a hole formed in the adjusting component 20, and the elastic element 30 is a spring located between the first connecting part 11 and the second connecting part 23. The two ends of the spring are respectively connected to pins passing through the first connecting part 11 and the second connecting part 23. The rotation axis of the cleaning roller 12 is parallel to the rotation axis of the circular blade 200, and the rotation axis of the adjusting component 20 relative to the mounting block 13 is parallel to the rotation axis of the cleaning roller 12. It should be noted that the outer circumferential surface of the cleaning roller 12 is provided with an adhesive structure such as glue, so that when the circular blade 200 rotates, it can remove impurities from the circular blade 200, thereby achieving a cleaning effect.

[0033] In this embodiment, the circular blade 200 is mounted on the base 300. One end of the mounting block 13 is rotatably connected to the base 300, and the other end is rotatably connected to the cleaning roller 12. The outer circumferential surface of the cleaning roller 12 can abut against the outer circumferential surface of the circular blade 200. The rotation axis of the cleaning roller 12 is parallel to the rotation axis of the circular blade 200. A first circumferential direction 400 and a second circumferential direction 500 are defined. The second circumferential direction 500 is opposite to the first circumferential direction 400. The mounting block 13 can drive the cleaning roller 12 to make a circular motion around the connection between the base 300 and the mounting block 13 along the first circumferential direction 400. The first connecting part 11 can move along the first circumferential direction 400 with the cleaning roller 12. The cleaning roller 12 is located on one side of the circular blade 200 along the second circumferential direction 500, and the second connecting part 23 is located on one side of the first connecting part 11 along the first circumferential direction 400. When the adjusting component 20 moves along the first circumferential direction 400, the first connecting part 11 and the second connecting part 23 move away from each other along the first circumferential direction 400, and the stretching length of the elastic element 30 increases. When the adjusting component 20 moves along the first circumferential direction 400, the first connecting part 11 and the second connecting part 23 move closer to each other along the first circumferential direction 400, and the stretching length of the elastic element 30 decreases.

[0034] It is understood that the elastic element 30 is connected to the first connecting portion 11 and the second connecting portion 23 at both ends, respectively. The second connecting portion 23 is located on one side of the first connecting portion 11 along the first circumferential direction 400, and the cleaning roller 12 is disposed on one side of the circular blade 200 along the second circumferential direction 500. When the elastic element 30 is stretched, it can generate a force on the first connecting portion 11 along the first circumferential direction 400, so that the cleaning roller 12 moves closer to the circular blade 200 along the first circumferential direction 400. By adjusting the movement of the assembly 20 relative to the mounting block 13 along the first circumferential direction 400 or the second circumferential direction 500, the stretching length of the elastic element 30 can be changed, thereby changing the force generated by the elastic element 30 on the mounting block 13.

[0035] The cleaning device 100 of this invention connects a first connecting portion 11 and a second connecting portion 23 via an elastic element 30. The elastic element 30 applies an elastic force to the first connecting portion 11, causing the mounting block 13 to drive the cleaning roller 12 to press against the circular blade 200, thereby ensuring a tight fit between the cleaning roller 12 and the circular blade 200. The adjusting component 20 can be rotated relative to the mounting block 13, changing the distance between the first connecting portion 11 and the second connecting portion 23, thus adjusting the adhesion force between the cleaning roller 12 and the circular blade 200.

[0036] Please see Figures 1 to 4 In one embodiment of this implementation, the mounting block 13 and the adjusting component 20 are rotatably connected around a first axis. The mounting block 13 can rotate relative to the circular blade 200 around the first axis, and the elastic element 30 can drive the mounting block 13 to rotate relative to the adjusting component 20.

[0037] Specifically, the rotation axes of the cleaning roller 12 and the circular blade 200 are both parallel to the first axis. The mounting block 13 coincides with the rotation axis of the adjusting assembly 20. The mounting block 13 can drive the cleaning roller 12 to rotate around the first axis and approach the circular blade 200 along the first circumferential direction 400. When the adjusting assembly 20 rotates around the first axis, the first connecting part 11 and the second connecting part 23 move relative to each other along the first circumferential direction 400 or the second circumferential direction 500.

[0038] It is understandable that the mounting block 13 coincides with the pivot of the adjustment assembly 20, which makes the circumferential movement paths of the first connecting part 11 and the second connecting part 23 concentric, and facilitates the adjustment assembly 20 to adjust the adhesion force between the cleaning roller 12 and the circular knife 200.

[0039] Please see Figures 1 to 4 In one embodiment of this implementation, the adjustment component 20 includes a traction member 21 and an adjustment member 22. The traction member 21 is rotatably connected to the mounting block 13, and the second connecting part 23 is disposed on the traction member 21. The adjustment member 22 is movably connected to the traction member 21. The adjustment member 22 can move relative to the traction member 21 to connect with the base 300 on which the circular blade 200 is mounted. The adjustment member 22 is used to restrict the movement of the traction member 21 relative to the circular blade 200.

[0040] Specifically, the adjusting component 22 is a screw, and the traction component 21 has a threaded hole 211. The screw is rotatably engaged with the threaded hole 211, and the screw can rotate in the threaded hole 211 to move along the axial direction of the threaded hole 211 and abut against the base 300.

[0041] Understandably, when the cleaning roller 12 abuts against the circular blade 200, the first connecting part 11 is relatively fixed to the circular blade 200. The adjusting member 22 can restrict the movement of the traction member 21 relative to the circular blade 200, so that the distance between the first connecting part 11 and the second connecting part 23 remains unchanged. This ensures that the force exerted by the elastic member 30 on the mounting block 13 remains unchanged, and consequently, the adhesion force between the cleaning roller 12 and the circular blade 200 remains unchanged. When the adjusting member 22 moves along the axial direction of the threaded hole 211 to the point where it no longer abuts against the base 300, the traction member 21 can rotate relative to the circular blade 200 to adjust the adhesion force between the cleaning roller 12 and the circular blade 200.

[0042] Please see Figures 1 to 4 In one embodiment of this implementation, the cleaning device 100 further includes a fixing member 40, which is used to connect with the base 300. The fixing member 40 has a strip groove 41 that extends in a direction parallel to the first axis. The strip groove 41 is used to connect the fixing member 40 and the circular blade 200. The traction member 21 is rotatably connected to the fixing member 40. The adjusting member 22 can move relative to the traction member 21 to abut against the fixing member 40.

[0043] Specifically, the fixing member 40 is cylindrical, and the axial direction of the fixing member 40 is parallel to the first axial direction. A strip groove 41 is formed on the circumferential surface of the fixing member 40. The strip groove 41 extends along the axial direction of the fixing member 40 and passes through the fixing member 40 in a direction perpendicular to the axial direction of the fixing member 40. The traction member 21 has a mating hole 212 that matches the size of the strip groove 41. The axial direction of the mating hole 212 is parallel to the first axial direction. The fixing member 40 passes through the mating hole 212. Part of the outer circumferential surface of the fixing member 40 mates with the hole wall of the mating hole 212. The threaded hole 211 connects to the mating hole 212.

[0044] It is understood that the fastener 40 and the base 300 can be connected by bolts passing through the strip groove 41. The strip groove 41 extends along the first axis direction, so that when the fastener 40 is installed on the base 300, the position of the fastener 40 can be adjusted in a direction parallel to the first axis direction. This allows the relative position of the cleaning roller 12 and the circular knife 200 to be adjusted in the first axis direction, thereby making the cleaning area of ​​the cleaning roller 12 relative to the circular knife 200 adjustable. The adjusting member 22 can abut against the part of the fastener 40 located in the mating hole 212 so that the distance between the first connecting part 11 and the second connecting part 23 remains unchanged.

[0045] Please see Figures 1 to 2 In one embodiment of this implementation, two mounting blocks 13 are provided, and the two mounting blocks 13 are arranged along the axial direction of the cleaning roller 12. The two mounting blocks 13 are respectively connected to the cleaning roller 12 from opposite sides of the cleaning roller 12.

[0046] Specifically, there are two mounting blocks 13, two adjusting components 20 and two elastic elements 30 arranged at intervals along the axial direction of the cleaning roller 12. The two mounting blocks 13 and the two adjusting components 20 are connected one-to-one, the two elastic elements 30 are connected one-to-one to the two mounting blocks 13, and the two elastic elements 30 are connected one-to-one to the two adjusting components 20.

[0047] Understandably, the two mounting blocks 13 are connected to the cleaning roller 12 from opposite sides. The two mounting blocks 13 can work together to fix the cleaning roller 12, which helps to improve the stability of the connection between the cleaning roller 12 and the base 300. The two adjusting components 20 at both ends of the cleaning roller 12 can rotate independently so that the elongation of the elastic element 30 at both ends of the cleaning roller 12 is different, thereby making the adhesion force between the two ends of the cleaning roller 12 and the circular knife 200 different, which helps to make the cleaning device 100 more applicable.

[0048] Please see Figure 1 and Figure 2In one embodiment of this implementation, the cleaning assembly 10 further includes a support rod 14, with both ends of the support rod 14 connected to two mounting blocks 13 respectively. The cleaning roller 12 is rotatably connected to the support rod 14, and the axial direction of the cleaning roller 12 is parallel to the axial direction of the support rod 14. A limiting member 15 is provided on the support rod 14, and the limiting member 15 is movably connected to the support rod 14. The limiting member 15 can move along the axial direction of the support rod 14 to abut against the cleaning roller 12, and the limiting member 15 can restrict the cleaning roller 12 from moving axially.

[0049] Specifically, the limiting member 15 and the support rod 14 can slide together along the axial direction of the support rod 14, and the limiting member 15 is disposed on one side of the cleaning roller 12 along the axial direction of the support rod 14. It can be understood that by limiting the movement of the cleaning roller 12 along the axial direction of the cleaning roller 12 by the limiting member 15, the cleaning roller 12 can clean the fixed area on the circular knife 200, which is beneficial to improving the cleaning effect of the cleaning device 100.

[0050] Please see Figure 1 and Figure 2 In one embodiment of this implementation, a bearing 16 is provided on the support rod 14, the inner ring of the bearing 16 is connected to the support rod 14, and the outer ring of the bearing 16 is connected to the cleaning roller 12.

[0051] Specifically, the axial direction of bearing 16 coincides with the axial direction of support rod 14. It can be understood that the outer and inner rings of bearing 16 can rotate relative to each other. By setting bearing 16, the friction between cleaning roller 12 and support rod 14 can be reduced, which helps to improve the service life of cleaning roller 12.

[0052] Please see Figure 1 and Figure 2 In one embodiment of this implementation, the inner ring of the bearing 16 is connected to the limiting member 15, and the bearing 16 can move along the axis of the support rod 14 with the limiting member 15. It is understood that during the installation of the cleaning roller 12, the cleaning roller 12 needs to be installed on the support rod 14 first, and then the limiting member 15 is adjusted so that it slides relative to the cleaning roller 12 to approach and abut against it. By placing the bearing 16 on the limiting member 15, the bearing 16 can complete its engagement with the cleaning roller 12 during the adjustment of the limiting member 15, which helps to improve the assembly efficiency of the cleaning roller 12.

[0053] Please see Figure 1 and Figure 2 In one embodiment of this implementation, two limiting members 15 are provided, and the two limiting members 15 are arranged at intervals along the axial direction of the support rod 14. The two limiting members 15 can abut against the cleaning roller 12 from opposite sides.

[0054] Specifically, two limiting members 15 are arranged on both sides of the cleaning roller 12 along the axial direction of the cleaning roller 12. It can be understood that by setting two limiting members 15, the limiting effect on the cleaning roller 12 is improved, which can further improve the cleaning effect of the cleaning roller 12 on the circular knife 200.

[0055] Please see Figure 3 and Figure 4 The second aspect of this utility model provides a die-cutting device, which includes a circular blade 200 and a cleaning device 100 according to any embodiment of the first aspect.

[0056] Specifically, the die-cutting equipment also includes a base 300, a circular blade 200 and a cleaning device 100, all of which are mounted on the base 300, with the outer circumferential surface of the cleaning roller 12 abutting against the outer circumferential surface of the circular blade 200.

[0057] The die-cutting equipment provided in the second aspect of this utility model has at least the following beneficial effects:

[0058] By incorporating the cleaning device 100 from the first aspect of this invention into the die-cutting equipment, the cleaning effect on the circular blade 200 can be improved.

[0059] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
