Description

Technical Field

[0001] This utility model relates to the field of processing machinery and equipment, specifically to a die-cutting machine. Background Technology

[0002] Die-cutting machines, as small pressing devices, are simple to manufacture and easy to operate, making them popular among users. Currently, some die-cutting machines use linear lifting structures such as drive cylinders or motors, while others use manual pressing. Due to the power drive device, there are certain differences in cost. However, both structures require a special feature: since the pressing process is a lifting action, guide rods and guide holes are necessary to ensure lifting accuracy.

[0003] However, the guide rods can affect the placement of the products to be die-cut on the platform, especially when dealing with large products, which must be cut to a width smaller than the spacing between the guide rods. Since users have varying product sizes, equipment with guide rods severely limits their usage needs.

[0004] In view of the problems existing in the prior art, this utility model designs and manufactures a die-cutting machine to overcome the above defects. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a die-cutting machine that eliminates the need for guide rods between the lifting pressure plate and the bottom platform, thus removing the restrictions on the placement of products to be die-cut.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a die-cutting machine, including a bottom platform, a lifting pressure plate that can be raised and lowered above the bottom platform, and different specifications of cutting tools can be installed at the bottom of the lifting pressure plate; The bottom platform is connected to a support arm at the rear. The support arm includes two support plates with a gap between them. A rotatable shaft is provided between the gaps above the two support plates, and an eccentric wheel is fixed on the shaft. A guide block is provided below the rotating shaft. The guide block is fixed on both sides to the inner sides of the two support plates of the support arm. A through hole is provided in the center of the guide block. A lifting rod is provided in the through hole. The lifting pressure plate is fixed at the lower end of the lifting rod. A boss is provided at the bottom of the through hole, the inner diameter of the boss is larger than the diameter of the lifting rod, a limiting platform is provided in the middle of the lifting rod, the diameter of the limiting platform is smaller than the diameter of the through hole, a compression spring is provided in the through hole, the compression spring is sleeved on the lifting rod, one end of the compression spring abuts against the boss, and the other end of the compression spring abuts against the limiting platform; A guide plate is connected to the top of the through hole, and a non-circular hole is provided in the center of the guide plate. The cross-section of the lifting rod above the limiting platform matches the shape of the non-circular hole. The non-circular hole cooperates with the lifting rod above the limiting platform to restrict the rotation of the lifting rod. One end of the rotating shaft passes through a support plate, and a handle is connected to the rotating shaft that passes through the support plate. The handle can drive the rotating shaft to rotate.

[0007] Preferably, there are two support arms, and the lower ends of the lifting rods on both support arms are connected to the lifting pressure plate.

[0008] Preferably, the pivots on the two support arms are integrally connected by a connecting shaft, and a handle is connected to the connecting shaft.

[0009] Preferably, the lower end of the lifting rod is provided with a threaded section, and the threaded section is provided with external threads; A nut is fixed above the lifting pressure plate, and the lifting pressure plate is screwed to the threaded section at the lower end of the lifting rod through the nut.

[0010] Preferably, the guide plate is detachably connected to the guide block by screws.

[0011] Preferably, a limiting rod is also provided on one side of the support plate with the handle, and the limiting rod can limit the downward pressing position of the handle.

[0012] Preferably, the lower end of the support arm is integrally connected to a horizontal arm, and the horizontal arm is connected to the bottom of the bottom platform.

[0013] Preferably, the bottom platform is provided with a plurality of feet, the height of which is greater than the height of the transverse arm.

[0014] Preferably, the two support plates of the support arm are connected by a number of reinforcing rods.

[0015] The advantages of this utility model are: 1. This utility model sets the guide structure on the lifting rod and guide block above the lifting pressure plate, ensuring that there is no structure between the lifting pressure plate and the bottom platform, thus meeting the size and area requirements of any product to be die-cut.

[0016] 2. This utility model utilizes the non-circular hole on the guide plate and the non-circular cross-section of the lifting rod above the limiting platform to guide and cooperate, thereby preventing the rotation of the lifting rod and limiting the rotation of the lifting pressure plate, ensuring the punching accuracy of the punching tool. The use of compression springs ensures the rapid lifting of the lifting rod, reducing the labor intensity of the operator.

[0017] 3. This utility model utilizes a nut to connect with the lifting rod, which allows for height adjustment of the lifting pressure plate connected to the nut. When the lifting rod needs to rotate, the guide plate only needs to be temporarily removed, the position adjusted, and the guide plate reinstalled to re-limit the rotation of the lifting rod.

[0018] 4. This utility model can also be provided with two support arms and two corresponding lifting rods. In this way, the two lifting rods can be used for direct guidance without the need to provide a guide plate with a non-circular hole. Attached Figure Description

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings. Example 1

[0022] like Figures 1 to 4 As shown, a die-cutting machine includes a bottom platform 1, and a lifting pressure plate 2 that can be raised and lowered is provided above the bottom platform 1. Different specifications of cutting tools can be installed at the bottom of the lifting pressure plate 2. When the product to be die-cut is placed on the bottom platform 1, the lifting pressure plate 2 drives the cutting tool to cut downwards.

[0023] The bottom platform 1 is connected to the rear side of the support arm 3. The support arm 3 includes two support plates. The two support plates are connected by several reinforcing rods 11. There is a gap between the two support plates. A rotating shaft 5 is provided between the gaps above the two support plates. An eccentric wheel 4 is fixed on the rotating shaft 5.

[0024] like Figure 6 , Figure 7 As shown, a guide block 13 is provided below the rotating shaft 5. The guide block 13 is fixed on both sides of the inner side of the two support plates of the support arm 3. A through hole 14 guide plate 15 is provided in the center of the guide block 13. A lifting rod 7 is provided in the through hole 14 guide plate 15. A lifting pressure plate 2 is fixed at the lower end of the lifting rod 7.

[0025] This utility model has a through hole 14 guide plate; a boss 16 is provided at the bottom of the boss 16, the inner diameter of the boss 16 is larger than the diameter of the lifting rod 7, a limiting platform 18 is provided in the middle of the lifting rod 7, the diameter of the limiting platform 18 is smaller than the diameter of the through hole 14 guide plate 15, and a compression spring 17 is provided in the through hole 14 guide plate 15. The compression spring 17 is sleeved on the lifting rod 7, one end of the compression spring 17 abuts against the boss 16, and the other end of the compression spring 17 abuts against the limiting platform 18. The above structure makes the lifting rod 7 always have an upward tendency, which in turn makes the lifting pressure plate 2 have an upward tendency, so that the lifting pressure plate 2 can automatically rise after the operator finishes pressing down and punching the product.

[0026] A guide plate with a through hole 14 is attached to the top of the guide plate 15. The guide plate is detachably connected to the guide block 13 by screws. A non-circular hole is provided in the center of the guide plate. The cross-section of the lifting rod 7 above the limiting platform 18 matches the shape of the non-circular hole. The non-circular hole cooperates with the lifting rod 7 above the limiting platform 18 to restrict the rotation of the lifting rod 7. This utility model utilizes the non-circular hole on the guide plate and the non-circular cross-section of the lifting rod 7 above the limiting platform 18 to guide and cooperate, thereby preventing the rotation of the lifting rod 7 and limiting the rotation of the lifting pressure plate 2, ensuring the punching accuracy of the punching tool. In addition, by setting the above-mentioned guiding structure on the lifting rod 7 and the guide block 13 above the lifting pressure plate 2, it is ensured that there is no structure between the lifting pressure plate 2 and the bottom platform 1, thus meeting the size and area requirements of any product to be die-cut.

[0027] In this invention, one end of the rotating shaft 5 passes through a support plate, and a handle 6 is connected to the rotating shaft 5 extending out of the support plate. The handle 6 can drive the rotating shaft 5 to rotate, which in turn drives the eccentric wheel 4 to rotate. The side wall of the eccentric wheel 4 presses down on the upper end of the lifting rod 7, thereby achieving manual punching. Alternatively, a lifting cylinder can be directly installed at the upper end of the lifting rod 7, and the extension of the lifting cylinder can directly drive the lifting rod 7 to descend. Example 2

[0028] like Figure 5As shown, this embodiment has two support arms 3, and the lower ends of the lifting rods 7 on both support arms 3 are connected to the lifting pressure plate 2. The rotating shafts 5 on the two support arms 3 are integrally connected by a connecting shaft, and a handle 6 is connected to the connecting shaft. Since two support arms 3 are provided, two corresponding lifting rods 7 are also provided, so the two lifting rods 7 can be used directly for guidance, without the need to provide a corresponding guide plate with a non-circular hole.

[0029] In both embodiments described above, the lower end of the lifting rod 7 is provided with a threaded section, on which external threads are provided. A nut 8 is fixed above the lifting pressure plate 2, and the lifting pressure plate 2 is screwed to the threaded section at the lower end of the lifting rod 7 via the nut 8. Specifically, by using the nut 8 to connect with the lifting rod 7, the height of the lifting pressure plate 2 connected to the nut 8 can be adjusted. When the lifting rod 7 needs to rotate, the guide plate only needs to be temporarily removed, its position adjusted, and then reinstalled to re-limit the rotation of the lifting rod 7.

[0030] The present invention has a limiting rod 10 on one side of the support plate with handle 6. The limiting rod 10 can limit the downward pressing position of handle 6 and prevent excessive downward pressure from damaging the tool.

[0031] To further improve the stability of the support arm 3, and thus the lifting stability of the lifting plate 2, the lower end of the support arm 3 is preferably integrally connected to a horizontal arm 12, which is connected to the bottom of the bottom platform 1. The bottom of the bottom platform 1 is provided with several feet 9, the height of which is greater than the height of the horizontal arm 12.

[0032] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
