Abstract

[0002] During the processing of products, they need to be die-cut by a die-cutting machine, that is, the products are die-cut into specific shapes. In order to ensure that the products can be stably unfolded during die-cutting, the upper die seat will descend to directly squeeze the products on the lower die seat, thereby generating tension on the products so that the products can be stably opened for die-cutting. However, different products have different thicknesses, resulting in different extrusion forces on products of different thicknesses when they are squeezed, resulting in different tensions, which will cause changes in the die-cutting effect. Therefore, in order to enable products of different thicknesses to stably generate adaptive tension and ensure the die-cutting effect of the products, we propose a tension-adjustable die-cutting machine.

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model provides Figure 1-3 The tension-adjustable die-cutting machine shown in the figure includes a lower die base 102, a guiding mechanism, an extruding mechanism and an adjusting mechanism. An upper die base 101 is arranged above the lower die base 102, and a hydraulic cylinder for lifting the upper die base 101 is arranged at the top of the upper die base 101. The upper die base 101 is lowered by the hydraulic cylinder, and the product can be die-cut between the upper die base 101 and the lower die base 102.
[0023] Among them, the guiding mechanism is arranged at the top of the lower mold base 102, and is used for moving the product at the top of the lower mold base 102. The guiding mechanism includes a plurality of first fixed frames 301 fixedly connected to the side of the top of the lower mold base 102. The inner wall of the first fixed frame 301 is rotatably connected with a guide wheel 302. There are two guide wheels 302, which are respectively arranged on both sides of the top of the lower mold base 102. That is, by rotating the guide wheels 302, the product can be stably moved at the top of the lower mold base 102.
[0024] Preferably, the extrusion mechanism is arranged on both sides of the upper die base 101, and an elastic mechanism is arranged above the extrusion mechanism, which is used for the upper die base 101 to descend so that the extrusion mechanism extrude the product. The extrusion mechanism includes a second fixed frame 401, and the inner wall of the second fixed frame 401 is rotatably connected with an extrusion wheel 402. The elastic mechanism is arranged between the second fixed frame 401 and the adjustment plate 201. The downward movement of the upper die base 101 can drive the extrusion mechanism to descend, so that the extrusion wheel 402 presses against the product at the top of the lower die base 102, which can generate tension on the product at the top of the lower die base 102, so that the product can be stably die-cut by the upper die base 101 at the top of the lower die base 102.
[0025] Furthermore, the elastic mechanism includes a spring 501, the bottom end of the spring 501 is connected to the top end of the second fixed frame 401, the top end of the spring 501 is connected to the bottom end of the adjustment plate 201, and a connecting mechanism is arranged between the second fixed frame 401 and the adjustment plate 201. Through the arrangement of the spring 501, after the upper die base 101 moves downward, the extrusion wheel 402 first contacts the product, and then the upper die base 101 continues to move downward. Due to the limitation of the extrusion wheel 402 by the product, the extrusion wheel 402 can be moved upward relative to the upper die base 101, so that the spring 501 is compressed, and the product can be stably extruded to generate tension, so that the product can be stably unfolded for die-cutting, thereby ensuring the die-cutting effect of the product.
[0026] Furthermore, the connecting mechanism includes a connecting rod 502 fixedly connected to the top of the second fixed frame 401, a connecting hole 503 is opened at the bottom end of the adjusting plate 201, the outer wall of the connecting rod 502 is movably connected with the inner wall of the connecting hole 503, and the top of the outer wall of the connecting rod 502 is fixedly sleeved with a limiting ring 504. The connecting rod 502 and the connecting hole 503 are limited to each other, so that the extrusion mechanism and the adjustment mechanism can be stably connected. At the same time, the spring 501 is limited by the connecting rod 502, so that the spring 501 can work stably. At the same time, the outer diameter of the limiting ring 504 is larger than the inner diameter of the connecting hole 503, so that the connecting rod 502 can be avoided from separating from the adjusting plate 201, thereby ensuring that the extrusion mechanism can work stably.
[0027] In a preferred embodiment, the adjustment mechanism includes a movably arranged adjustment plate 201, the adjustment plate 201 is connected to the elastic mechanism and is used to change the positioning position of the elastic mechanism, a moving mechanism is arranged at the top of the adjustment plate 201, and the moving mechanism includes a fixed plate 601 fixedly connected to the outer wall of the upper mold base 101, a threaded hole 603 is opened at the top of the fixed plate 601, a screw 602 is threadedly connected to the inner wall of the threaded hole 603, the bottom end of the screw 602 is rotatably connected to the top of the adjustment plate 201, a limiting mechanism is arranged between the fixed plate 601 and the adjustment plate 201, and a limit mechanism is arranged between the fixed plate 601 and the adjustment plate 201, and the ... By rotating the screw rod 602 in the groove hole 603, the screw rod 602 can be raised or lowered, thereby raising or lowering the adjustment plate 201, and changing the positioning position of the top end of the spring 501. That is, when the product is thicker, the adjustment plate 201 can be raised by rotating the screw rod 602, and when the product is thinner, the adjustment plate 201 can be lowered by rotating the screw rod 602 in the opposite direction. The height of the adjustment plate 201 can be adjusted according to the thickness of the product, so that when the extrusion wheel 402 extrudes the product, the product generates appropriate tension, thereby ensuring that the product can be stably die-cut and improving the die-cutting effect of the product.
[0028] Preferably, the limiting mechanism includes a plurality of limiting rods 701 fixedly connected to the top of the adjusting plate 201, a plurality of limiting holes 702 are opened at the top of the fixing plate 601, and the outer walls of the plurality of limiting rods 701 are movably interlaced with the outer walls of the plurality of limiting holes 702, respectively. Through the mutual limitation of the fixing plate 601 and the screw 602, when the screw 602 rotates to drive the adjusting plate 201 to rise and fall, the lateral force brought to the adjusting plate 201 by the rotation of the screw 602 can be offset, so that the adjusting plate 201 can be stably lifted and lowered, thereby ensuring the stability of the working of the adjusting mechanism.
[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
