Abstract
Description
Technical Field
[0001] This utility model relates to the field of die-cutting technology, and in particular to a material changing device and a die-cutting equipment. Background Technology
[0002] In the die-cutting production process, the material strip is processed by the die-cutting equipment. In the existing technology, when changing the material roll of the die-cutting equipment, the material strip needs to be cut from the material roll, which will cause the material strip to lose tension, resulting in material strip deviation and the die-cutting production cannot proceed normally. Therefore, the die-cutting equipment needs to be stopped during the material roll change process, which will lead to a reduction in die-cutting production efficiency. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a material changing device and a die-cutting machine that can change material rolls without stopping the machine.
[0004] In a first aspect, this utility model provides a material changing device, which includes a base and an adjusting mechanism. The base is used to connect to a platform; the adjusting mechanism includes a resistance roller and an adjusting component. The resistance roller is rotatably mounted on the base about its axis, which is parallel to a first direction. The outer circumferential surface of the resistance roller is used to abut against the material belt. The adjusting component is movably connected to the base and abuts against the end face of the resistance roller. The adjusting component can move relative to the base along the first direction to change the contact force between the adjusting component and the resistance roller.
[0005] The material changing device provided in the first aspect of this utility model has at least the following beneficial effects:
[0006] The outer circumferential surface of the resistance roller is used to abut against the material belt. When the material belt is conveyed, it drives the resistance roller to rotate. The adjustment component abuts against the resistance roller from one side along the first direction, and the adjustment component can move relative to the base along the first direction to increase the friction force between the adjustment component and the resistance roller. This makes it necessary for the material belt to overcome greater resistance when it drives the resistance roller to rotate, so that the resistance roller can tension the material belt. This helps to reduce the risk of material belt deviation and enables the replacement of material rolls without stopping the machine.
[0007] In one embodiment of this implementation, the adjusting component has an annular abutment surface, the axis of which coincides with the axis of the resistance roller, and the annular abutment surface can abut against the end face of the resistance roller.
[0008] In one embodiment of this implementation, the adjustment assembly includes an adjustment member, an elastic member, and an abutment member arranged along a first direction. The abutment member is movable relative to the base along the first direction and is used to abut against the resistance roller. One end of the elastic member is connected to the abutment member, and the other end is connected to the adjustment member. The adjustment member and the abutment member are movably connected. When the adjustment member moves relative to the abutment member, it can compress the elastic member so that the elastic member pushes the abutment member toward the resistance roller.
[0009] In one embodiment of this implementation, the material changing device further includes a rotating component and a pressing component. The pressing component is located on one side of the resistance roller in the radial direction. The pressing component has a pressing surface parallel to the first direction. The pressing surface is used to abut against the material belt. The pressing component is mounted on the rotating component. The rotating component is rotatably connected to the base. When the rotating component rotates, it drives the pressing component to rotate around an axis parallel to the first direction.
[0010] In one embodiment of this implementation, the material changing device further includes a material guide, which is mounted on a base and has a material guide surface perpendicular to the first direction. The material guide surface is used to abut against the material belt to restrict the movement of the material belt along the first direction.
[0011] In one embodiment of this implementation, the guide member is movably disposed on the base along a first direction.
[0012] In one embodiment of this implementation, the material changing device further includes a squeezing roller, which is rotatably connected to the base. The axis of the squeezing roller is parallel to the first direction, and the outer peripheral surface of the squeezing roller is used to abut against the material strip to push the material strip toward the outer peripheral surface of the resistance roller.
[0013] In one embodiment of this implementation, the material changing device includes a slider, which is movably connected to the base. An extrusion roller is mounted on the slider. When the slider moves, it drives the extrusion roller to move relative to the resistance roller in a direction perpendicular to the first direction.
[0014] In one embodiment of this implementation, the material changing device includes a mounting block, which is movably connected to the base. A resistance roller is mounted on the mounting block, and when the mounting block moves, it can drive the resistance roller to move relative to the base in a direction perpendicular to the first direction.
[0015] Secondly, the present invention provides a die-cutting device, which includes a base and a material changing device according to any embodiment of the first aspect of the invention, wherein the base is mounted on the base.
[0016] The die-cutting equipment provided in the second aspect of this utility model has at least the following beneficial effects:
[0017] By incorporating the material changing device of the first aspect of this invention into the die-cutting equipment, it is possible to change the material roll without stopping the machine.

[0032] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
[0033] This utility model provides a material changing device 100. Please refer to [link / reference]. Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural schematic diagram of the material changing device 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 A three-dimensional structural schematic diagram of the adjustment mechanism 20 is shown. The material changing device 100 includes a base 10 and an adjustment mechanism 20. The base 10 is used to connect to the base platform; the adjustment mechanism 20 includes a resistance roller 21 and an adjustment component 22. The resistance roller 21 is rotatably mounted on the base 10 about its axis, and the axis of the resistance roller 21 is parallel to a first direction. The outer peripheral surface of the resistance roller 21 is used to abut against the material belt. The adjustment component 22 is movably connected to the base 10 and abuts against the end face of the resistance roller 21. The adjustment component 22 can move relative to the base 10 along the first direction to change the contact force between the adjustment component 22 and the resistance roller 21.
[0034] Specifically, the first direction is parallel to the Y direction. The adjusting mechanism 20 also includes a bearing and a first shaft 70. The axis of the first shaft 70 is parallel to the Y direction and is mounted on the base 10. The inner ring of the bearing is connected to the first shaft 70, and the axis of the bearing coincides with the axis of the first shaft 70. The resistance roller 21 is fitted with the outer ring of the bearing, and the axis of the bearing coincides with the axis of the resistance roller 21. The end faces of the resistance roller 21 are located on opposite sides of the resistance roller 21 along the Y direction. The adjusting assembly 22 is mounted on the first shaft 70 and can move along the axis of the first shaft 70. The outer circumferential surface of the resistance roller 21 can abut against the conveyor belt along the X direction.
[0035] It is understandable that by setting a bearing on the first shaft 70 and mounting the resistance roller 21 on the bearing, a rotatable connection between the resistance roller 21 and the base 10 can be achieved. When the adjusting component 22 moves relative to the base 10, the adjusting component 22 can contact the end face of the resistance roller 21 and exert pressure on the resistance roller 21. When the adjusting component 22 moves in a direction closer to the resistance roller 21, the pressure exerted by the adjusting component 22 on the resistance roller 21 can increase; when the adjusting component 22 moves in a direction away from the resistance roller 21, the pressure exerted by the adjusting component 22 on the resistance roller 21 can decrease, thereby changing the frictional force that the resistance roller 21 needs to overcome when rotating. When the conveyed belt in the X direction abuts against the outer circumferential surface of the resistance roller 21, it can drive the resistance roller 21 to rotate around an axis parallel to the Y direction.
[0036] It should be noted that during the die-cutting process, the material strip is fed by a feed roller (not shown) and pulled by a pull roller (not shown). The feed roller and pull roller are located on opposite sides of the resistance roller 21 along the X direction. One end of the material strip is wound onto the feed roller to form a coil, and the other end extends along the X direction to pass over the outer circumference of the resistance roller 21 and connects to the pull roller. The pull roller can pull the material strip in the X direction away from the feed roller to convey the material strip. The feed roller can provide tension to the material strip in the direction away from the pull roller to work with the pull roller to tension the material strip. When it is necessary to replace the coil on the feed roller, the material strip and the coil must be cut first. After the material strip and the coil are separated, the traction of the feed roller is lost, which may cause the material strip to loosen and deviate. When the material strip is not tractioned by the feed roller, the resistance roller 21 can provide resistance to the conveying material strip in the X direction away from the pull roller to keep the material strip taut when it is pulled by the pull roller.
[0037] The material changing device 100 of this utility model has an outer peripheral surface of the resistance roller 21 for contacting the material belt. When the material belt is conveyed, it drives the resistance roller 21 to rotate. The adjusting component 22 contacts the resistance roller 21 from one side along the first direction, and the adjusting component 22 can move relative to the base 10 along the first direction to increase the friction force between the adjusting component 22 and the resistance roller 21. This makes it necessary for the material belt to overcome greater resistance when it drives the resistance roller 21 to rotate, so that the resistance roller 21 can tension the material belt. This helps to reduce the risk of material belt deviation and enables the replacement of material rolls without stopping the machine.
[0038] In one embodiment of this implementation, please refer to Figures 1 to 3 , Figure 3 yes Figure 2 A disassembled schematic diagram of the adjustment component 22. The adjustment component 22 has an annular abutment surface 2231, the axis of which coincides with the axis of the resistance roller 21, and the annular abutment surface 2231 can abut against the end face of the resistance roller 21.
[0039] Specifically, the axis of the annular contact surface 2231 is parallel to the Y direction. It can be understood that when the resistance roller 21 rotates and the annular contact surface 2231 contacts the end face of the resistance roller 21, the adjusting assembly 22 can provide the same force to the resistance roller 21 at various points on the annular contact surface 2231. This ensures that the force is evenly distributed across the circumference of the resistance roller 21's end face, which helps to make the rotation of the resistance roller 21 smoother.
[0040] In one embodiment of this implementation, please refer to Figures 1 to 3 The adjustment assembly 22 includes an adjustment member 221, an elastic member 222, and an abutment member 223 arranged along a first direction. The abutment member 223 can move relative to the base 10 along the first direction and is used to abut against the resistance roller 21. One end of the elastic member 222 is connected to the abutment member 223, and the other end is connected to the adjustment member 221. The adjustment member 221 is movably connected to the abutment member 223. When the adjustment member 221 moves relative to the abutment member 223, it can compress the elastic member 222 so that the elastic member 222 pushes the abutment member 223 toward the resistance roller 21.
[0041] Specifically, the abutment 223 is located on the side of the adjusting member 221 facing the resistance roller 21, the elastic member 222 is located between the abutment 223 and the adjusting member 221, the elastic member 222 is a spring, the first shaft 70 is provided with a thread, the adjusting member 221 is rotatably mounted on the first shaft 70, and the adjusting member 221 is threadedly engaged with the first shaft 70.
[0042] It is understandable that the adjusting member 221 is used for user rotation. When the adjusting member 221 rotates, it moves along the axis of the first shaft 70. When the adjusting member 221 is close to the resistance roller 21, the adjusting member 221 compresses the elastic member 222, which increases the force of the elastic member 222 on the abutment member 223, thereby enabling the abutment member 223 to press the resistance roller 21 tightly. When the adjusting member 221 is away from the resistance roller 21, the elastic member 222 can extend, which reduces the force of the elastic member 222 on the abutment member 223, thereby enabling the abutment member 223 to relax the resistance roller 21, and thus changing the frictional force generated by the abutment member 223 on the resistance roller 21. During rotation, the resistance roller 21 will generate a tangential force relative to the axis of the resistance roller 21 on the abutment 223. By setting the elastic element 222, the abutment 223 can prevent the tangential force relative to the axis of the resistance roller 21 from being directly transmitted to the adjusting element 221. This helps to reduce the risk that the adjusting element 221 will be driven by the resistance roller 21, causing the resistance roller 21 to be pressed or loosened unexpectedly.
[0043] In one embodiment of this implementation, please refer to Figure 1 and Figure 4 , Figure 4 yes Figure 1 The diagram shows the structure of the rotating component 31 and the pressing component 32. The material changing device 100 also includes a rotating component 31 and a pressing component 32. The pressing component 32 is located on one side of the resistance roller 21 in the radial direction. The pressing component 32 has a pressing surface 321 parallel to the first direction. The pressing surface 321 is used to abut against the material belt. The pressing component 32 is mounted on the rotating component 31. The rotating component 31 is rotatably connected to the base 10. When the rotating component 31 rotates, it drives the pressing component 32 to rotate around an axis parallel to the first direction.
[0044] Specifically, the pressing component 32 and the rotating component 31 are bolted together. One end of the pressing component 32 is connected to the rotating component 31, and the other end is away from the rotating component 31 and extends in a direction perpendicular to the Y direction. The rotating component 31 and the pressing component 32 are located on one side of the adjusting mechanism 20 along the X direction. When the rotating component 31 drives the pressing component 32 to rotate, the angle between the pressing surface 321 and the Z direction changes.
[0045] It is understandable that the pressing component 32 can push the material belt towards the outer circumference of the resistance roller 21 through the pressing surface 321. The material belt can move along the pressing surface 321. The rotating component 31 drives the pressing component 32 to rotate, which enables the pressing component 32 to press the material belt conveyed to the resistance roller 21 from different angles, which is beneficial to improving the adaptability of the material changing device 100.
[0046] In one embodiment of this implementation, please refer to Figure 1 and Figure 5 , Figure 5 yes Figure 1A schematic diagram of the structure of the guide component 41. The material changing device 100 also includes a guide component 41, which is mounted on the base 10. The guide component 41 has a guide surface 411 perpendicular to the first direction. The guide surface 411 is used to abut against the material belt to restrict the movement of the material belt along the first direction.
[0047] Specifically, there are two guide members 41, which are arranged at intervals along the Y direction and form two opposing guide surfaces 411. It can be understood that the material belt can pass through the gap between the two guide members 41, and the two guide surfaces 411 abut against the material belt from both sides along the Y direction to restrict the movement of the material belt along the Y direction, which helps to reduce the risk of material belt misalignment.
[0048] In one embodiment of this implementation, please refer to Figure 1 and Figure 5 The guide component 41 can be movably disposed on the base 10 along the first direction.
[0049] Specifically, a second shaft 80 extending along the Y direction is provided on the base 10, and two guide members 41 are slidably engaged with the second shaft 80. It can be understood that by slidably engaging the guide members 41 with the second shaft 80, the interval between the two guide members 41 can be adjusted, which is beneficial for accommodating material strips of different widths.
[0050] In one embodiment of this implementation, please refer to Figure 1 The material changing device 100 also includes a pressing roller 51, which is rotatably connected to the base 10. The axis of the pressing roller 51 is parallel to the first direction, and the outer peripheral surface of the pressing roller 51 is used to abut against the material belt to push the material belt toward the outer peripheral surface of the resistance roller 21.
[0051] Specifically, the extrusion roller 51 is located on one side of the resistance roller 21 along the Z direction. It can be understood that the extrusion roller 51 pushes the material strip towards the outer circumferential surface of the resistance roller 21, which can make the material strip adhere tightly to the outer circumferential surface of the resistance roller 21, and is beneficial to improving the friction force between the resistance roller 21 and the material strip.
[0052] In one embodiment of this implementation, please refer to Figure 1 The material changing device 100 includes a slider 52, which is movably connected to the base 10. The extrusion roller 51 is mounted on the slider 52. When the slider 52 moves, it drives the extrusion roller 51 to move relative to the resistance roller 21 in a direction perpendicular to the first direction.
[0053] Specifically, the slider 52 and the base 10 are slidably engaged in the Z-direction, and the extrusion roller 51 is rotatably connected to the slider 52. It can be understood that the outer circumferential surface of the extrusion roller 51 passes between the outer circumferential surface of the resistance roller 21. When the slider 52 drives the extrusion roller 51 to move, the outer circumferential surface of the extrusion roller 51 approaches the outer circumferential surface of the resistance roller 21, which changes the distance between the outer circumferential surfaces of the extrusion roller 51 and the resistance roller 21, thus facilitating the material changing device 100 to adapt to material strips of different thicknesses.
[0054] In one embodiment of this implementation, please refer to Figure 1 The material changing device 100 includes a mounting block 60, which is movably connected to the base 10. The resistance roller 21 is mounted on the mounting block 60. When the mounting block 60 moves, it can drive the resistance roller 21 to move relative to the base 10 in a direction perpendicular to the first direction.
[0055] Specifically, a groove 11 is provided on the base 10, extending along the Z direction. The mounting block 60 is slidably engaged with the groove 11, and the resistance roller 21 is rotatably connected to the mounting block 60. It can be understood that under different conditions, the material belt is conveyed at different positions in the Z direction. The mounting block 60 can drive the resistance roller 21 to move relative to the base 10 along the Z direction, allowing the resistance roller 21 to contact the material belt at different positions in the Z direction, thus improving the adaptability of the material changing device 100.
[0056] Secondly, please refer to Figure 1 The present invention provides a die-cutting device, which includes a base and a material changing device 100 according to any embodiment of the first aspect of the invention, wherein the base 10 is mounted on the base.
[0057] Specifically, the base 10 and the platform can be connected by bolts, welding, magnetic attraction, or adhesive. The die-cutting equipment also includes a feeding roller and a pulling roller, both of which are mounted on the platform. The feeding roller and the pulling roller are located on opposite sides of the resistance roller 21 along the X direction. The feeding roller is connected to the material strip, one end of which is wound around the feeding roller to form a roll, and the other end extends along the X direction to pass over the outer circumference of the resistance roller 21 and connects to the pulling roller.
[0058] Understandably, the pull roller can pull the belt in the X direction away from the feed roller to convey the belt. The feed roller can provide tension to the belt in the direction away from the pull roller to work together with the pull roller to tension the belt. By setting the resistance roller 21, the resistance roller 21 can provide resistance to the conveyed belt in the X direction. When the belt is not pulled by the feed roller, the resistance roller 21 can work together with the pull roller to tension the belt.
[0059] The die-cutting equipment of this utility model incorporates the material changing device 100 in the first aspect embodiment of this utility model, which enables the material roll to be changed without stopping the machine.
[0060] 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. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
