Description

Technical Field

[0001] This application relates to the field of printing equipment technology, and in particular to a tool assembly for a die-cutting machine. Background Technology

[0002] Die-cutting machines are specialized equipment used to cut or punch holes in various materials. Currently, products need to be produced with dense holes using die-cutting machines. However, the positions of existing die-cutting machine blades are fixed, making it impossible to control the spacing between adjacent holes. The processing requirements for dense holes also increase the difficulty of blade design and manufacturing. Utility Model Content

[0003] To improve the flexibility of die-cutting machines, this application provides a tool assembly for die-cutting machines.

[0004] The cutting tool assembly for a die-cutting machine provided in this application adopts the following technical solution:

[0005] A tool assembly for a die-cutting machine includes a tool and a support housing. The support housing is provided with a first support frame and a second support frame, and the first support frame and the second support frame are movable on the support housing by an adjustment component. The first support frame is provided with a first blade row for placing the tool, and the second support frame is provided with a second blade row for placing the tool. The first support frame and the second support frame are provided with a control component for controlling the lifting and lowering of the tool. Both the first blade row and the second blade row are provided with tools, and the tools on the first blade row and the tools on the second blade row are arranged alternately.

[0006] By adopting the above technical solution, the two support frames move on the support housing through adjusting components, thereby adapting to the processing needs of materials of different sizes and shapes, improving the applicability and flexibility of the equipment. Furthermore, by setting two staggered cutting tools, it is convenient to produce closely spaced holes, reducing the manufacturing difficulty of the cutting tools.

[0007] Optionally, the control component includes a drive shaft that passes through the first support frame. A cam is provided on the drive shaft. A movable plate is slidably disposed within the first support frame. The top of the movable plate contacts the outer edge of the cam. Vertically arranged springs are provided on both sides of the movable plate, and the other end of the springs is connected to the first support frame.

[0008] By adopting the above technical solution, the drive shaft rotates, which in turn drives the cam to rotate. When the side of the cam furthest from the shaft contacts the moving plate, the moving plate moves downward; when the side of the cam closest to the shaft contacts the moving plate, the moving plate moves upward. Furthermore, a spring is used to assist the moving plate in resetting upward, thereby achieving vertical movement.

[0009] Optionally, a dovetail groove is provided on the side wall of the first support frame, and a slider is provided on the side wall of the movable plate. The slider is inserted into the dovetail groove and slides in cooperation with the dovetail groove, and the spring is disposed on the slider.

[0010] By adopting the above technical solution, the slider slides along the dovetail groove, making the movement of the moving plate more stable and avoiding problems such as deviation or jamming during movement. At the same time, the spring setting allows the moving plate to move up and down smoothly, thereby ensuring more precise and stable lifting and lowering of the tool.

[0011] Optionally, the adjustment assembly includes a transmission screw that passes through the support housing. The support housing has a moving groove. The first support frame is threadedly engaged with the transmission screw and slides along the moving groove. The transmission screw is driven by a motor.

[0012] By adopting the above technical solution, the transmission screw rotates, and because the two support frames are threadedly engaged with the transmission screw and are close to each other with the support housing, the rotation of the support frames is restricted, thus allowing the two support frames to move. By setting a moving groove, the two support frames move along the moving mechanism, ensuring the stability of the movement.

[0013] Optionally, both the first support frame and the second support frame are provided with mounting slots, and both the first cutter bar and the second cutter bar are detachably connected to the mounting slots.

[0014] By adopting the above technical solutions, the replacement of the cutter head becomes more convenient and quick, thus improving the maintenance efficiency of the equipment.

[0015] Optionally, a first magnet is provided on the moving plate, and a second magnet is provided on the cutting tool, with the first magnet and the second magnet attracting each other.

[0016] By adopting the above technical solution, after the first and second cutter rows are fixed along the mounting groove, the cutters are naturally attracted by the magnets on the moving plate and attracted to the moving plate itself due to the magnetic attraction of the magnets. This ensures that the cutters remain stable during movement, preventing them from loosening or falling off due to vibration or impact, thereby improving die-cutting accuracy and work efficiency. At the same time, this magnetic connection method also facilitates quick cutter replacement, improving the flexibility and maintenance convenience of the equipment.

[0017] Optionally, both the first and second cutter banks are provided with vertical grooves, and the cutter slides along the vertical grooves.

[0018] By adopting the above technical solution, the cutting tool can slide up and down along the vertical groove, thereby realizing the height adjustment of the cutting tool and ensuring the stability of the cutting tool during movement.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. By setting up a transmission screw, a support housing, a moving groove, and two cutter bars, the transmission screw rotates. Since the two support frames are threadedly engaged with the transmission screw and are close to each other with the support housing, the rotation of the support frames is restricted, so the two support frames can move. The setting of the moving groove can ensure the stability of the movement.

[0021] 2. By setting up two support frames and staggering the cutters on the two cutter racks, it is convenient to produce closely spaced holes and reduce the manufacturing difficulty of the cutters;

[0022] 3. By configuring a drive shaft, cam, moving plate, spring, first magnet, and second magnet, the drive shaft rotates, causing the cam to rotate. When the side of the cam furthest from the shaft contacts the moving plate, the moving plate moves downward; when the side of the cam closest to the shaft contacts the moving plate, the moving plate moves upward. Furthermore, a spring assists the moving plate in returning to its original position, thus achieving vertical movement. Additionally, the tool moves vertically under magnetic force.

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a cutting tool assembly for a die-cutting machine. (Refer to...) Figure 1A tool assembly for a die-cutting machine includes a support housing 1 and a tool 2. The bottom of the support housing 1 is provided with a first support frame 3 and a second support frame 4. An adjustment assembly for controlling the first support frame 3 and the second support frame 4 is provided inside the support housing 1.

[0031] Reference Figure 1 and Figure 2 The adjustment assembly includes two lead screws 5, which are positioned opposite each other within the support housing 1 and pass through and are rotatably connected to the support housing 1. A motor 6 drives the two lead screws 5 to rotate. Two movable grooves 7 are positioned opposite each other at the bottom of the support housing 1, directly below the opposing lead screws 5. Both the first support frame 3 and the second support frame 4 are slidably engaged with the movable grooves 7, and both are threadedly engaged with the lead screws 5.

[0032] Reference Figure 1 , Figure 3 and Figure 4 The first support frame 3 and the second support frame 4 are equipped with control components for raising and lowering the tool 2. The control components include drive shafts 8, which rotatably pass through the length of the first support frame 3, and the second support frame 4 is also equipped with the same drive shaft 8 rotatably passing through its length. Cams 9 are provided on both drive shafts 8. Moving plates 10 are slidably installed inside both the first support frame 3 and the second support frame 4. The top of the moving plate 10 contacts the outer edge of the cam 9. Slider blocks 11 are provided on both sides of the moving plate 10. Dovetail grooves 12 are provided on the side walls of both the first support frame 3 and the second support frame 4. The sliders 11 are inserted into and slidably engaged with the dovetail grooves 12. A spring 13 is vertically installed on the slider 11, and the other end of the spring 13 is connected to the side wall of the support frame.

[0033] The drive shaft 8 rotates, which in turn drives the cam 9 to rotate. When the side of the cam 9 away from the shaft contacts the moving plate 10, the moving plate 10 moves downward. When the side of the cam 9 close to the shaft contacts the moving plate 10, the moving plate 10 moves upward, thus realizing the control action.

[0034] Reference Figure 1 , Figure 4 and Figure 5 Both the first support frame 3 and the second support frame 4 are provided with mounting slots 14, which have a T-shaped cross-section. A first blade rack 15 is detachably installed inside the first support frame 3, and a second blade rack 16 is detachably installed inside the second support frame 4. Both the first blade rack 15 and the second blade rack 16 are used to hold blades 2, and the blades 2 on the first blade rack 15 and the blades 2 on the second blade rack 16 are arranged alternately. A first magnet 17 is provided on the movable plate 10, and a second magnet 18 is provided on the blade 2. The first magnet 17 and the second magnet 18 attract each other, so that the blade 2 and the movable plate 10 move together.

[0035] During installation, the two blade racks are inserted along the mounting slots 14. Under the action of magnetism, the blade 2 adheres to the moving plate 10 and moves together, thereby realizing the movement of the blade 2. At the same time, this connection method also facilitates quick replacement of the blade 2, improving the flexibility and maintenance convenience of the equipment.

[0036] Reference Figure 1 , Figure 3 and Figure 5 In order to improve the stability of the tool 2 during the up and down movement, vertical grooves 19 are provided on both the first tool row 15 and the second tool row 16, and the tool 2 slides along the vertical grooves 19.

[0037] The implementation principle of a tool assembly for a die-cutting machine according to an embodiment of this application is as follows: by setting a first support frame 3 and a second support frame 4, and by adjusting the assembly to move on the support housing 1, the position of the tool 2 is adjusted, which controls the punching position on the one hand and can accurately match the position of the incoming material on the other hand.

[0038] By setting up a control component, the lifting and lowering action of the tool 2 is realized. The drive shaft 8 rotates, which in turn drives the cam 9 to rotate. When the side of the cam 9 away from the axis contacts the moving plate 10, the moving plate 10 moves downward; when the side of the cam 9 close to the axis contacts the moving plate 10, the moving plate 10 moves upward. By setting up two staggered tools 2, it is convenient to produce closely spaced holes and reduce the manufacturing difficulty of the tools 2.

[0039] When installing the cutter 2, the two cutter rows are inserted along the mounting groove 14. At this time, under the attraction of the first magnet 17 and the second magnet 18, the cutter 2 is naturally attracted by the magnet on the moving plate 10 and is attracted to the moving plate 10. This improves the die-cutting accuracy and enhances the flexibility and ease of maintenance of the equipment.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
