Description

Technical Field

[0001] This utility model relates to the field of printing and die-cutting technology, specifically to a die-cutting limiting device for printing equipment. Background Technology

[0002] In the printing industry, the die-cutting process plays a crucial role in the quality and production efficiency of printed materials. Precise die-cutting ensures neat edges and accurate dimensions, enhancing the product's aesthetics and integrity. The die-cutting stop device, as a key component controlling the cutting position during the die-cutting process, directly impacts the precision and stability of the die-cutting process.

[0003] Currently, most common die-cutting limiting devices use a screw-tightening structure to fix and adjust the position of the limiting components. In actual use, if the limiting position needs to be changed to accommodate different sizes of die-cutting materials, the operator needs to repeatedly tighten the screw with tools. The operation is cumbersome and time-consuming. Furthermore, under the influence of vibration generated by the equipment operation, the limiting components are prone to vibration and loosening, causing deviations in the limiting of the die-cutting materials. This results in inaccurate die-cutting, burrs on the edges of printed products, wasting materials and reducing product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a die-cutting limiting device for printing equipment, so as to solve the problem of inconvenient adjustment of traditional die-cutting limiting devices mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a die-cutting limiting device for printing equipment, comprising a guide roller, a bracket, and a plurality of guiding components disposed on the guide roller. The guiding components are assembled from a bracket, a limiting plate, and a pair of swing arms. The side wall of the bracket is provided with a circular hole adapted to the guide roller. The pair of swing arms are rotatably mounted on both sides of the circular hole, and an elastic member is connected between the pair of swing arms so that the pair of swing arms form an openable and closable clamping structure under the action of elastic potential energy.

[0006] Preferably, one end of the swing arm is rotatably sleeved with a guide rod, and the side wall of the bracket is provided with a sliding hole for the guide rod to pass through.

[0007] Preferably, the sliding hole is inclined.

[0008] Preferably, the elastic member is a spring plate sleeved on a pair of swing arms, the side wall of the swing arm is integrally formed with a protrusion, and a slot for accommodating the spring plate is provided at the center of the protrusion.

[0009] Preferably, a rubber pad is fixedly installed on the inner wall of the swing arm.

[0010] Preferably, the limiting plate is fixedly installed to the side wall of the bracket by bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a bracket, a limiting plate, a swing arm, and elastic components to form a guiding assembly on the guide roller. This assembly precisely limits the sides of the die-cut material, guiding it smoothly along a preset path through the guide roller and preventing material conveying deviation. Compared to the conventional screw-twisting structure of current limiting devices, this design is more convenient to operate, and the elastic clamping automatically compensates for errors and resists vibration, making it highly practical.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4This utility model provides a technical solution: a die-cutting limiting device for printing equipment, including a guide roller 1, a bracket 2, and several guiding components disposed on the guide roller 1. In actual application, the bracket 2 is fixedly installed below the guide roller 1 to limit the guiding components. The guiding components are assembled from a support 3, a limiting plate 4, and a pair of swing arms 5. The support 3 has an overall U-shaped structure, and the limiting plate 4 is fixedly installed on the side wall of the support 3 by bolts, which can limit the side of the die-cutting material to guide the die-cutting material smoothly through the guide roller 1 along a preset path, preventing the material from deviating or tilting during the conveying process, and ensuring a precise relative positional relationship between the die-cutting material and the guide roller 1. The side wall of the bracket 3 has a circular hole adapted to the guide roller 1. A pair of swing arms 5 are rotatably mounted on both sides of the circular hole. One end of the swing arm 5 is rotatably sleeved with a guide rod 7. The side wall of the bracket 3 has a sliding hole 10 through which the guide rod 7 passes. The sliding hole 10 is inclined. When the swing arm 5 is rotated by an external force, the angle can be compensated by the sliding of the guide rod 7 along the inclined sliding hole 10. An elastic component is connected between the pair of swing arms 5. A rubber pad 9 is fixedly installed on the inner wall of the swing arm 5. This arrangement can increase the friction between the swing arm 5 and the guide roller 1 so that the pair of swing arms 5 can form an openable clamping structure under the action of elastic potential energy. The elastic component is a spring plate 6 sleeved on the pair of swing arms 5. The side wall of the swing arm 5 is integrally formed with a protrusion. A slot 8 for accommodating the spring plate 6 is provided at the center of the protrusion. Stable assembly of the spring plate 6 can be achieved without additional fixing parts. The spring plate 6 is fitted onto a pair of swing arms 5 as an elastic component. Its elastic potential energy can drive the swing arms 5 to automatically reset and form a closed clamp. When the swing arms 5 rotate under the action of external force, the spring plate 6 deforms and stores energy. After the external force is released, it can quickly drive the swing arms 5 to return to the clamping state.

[0020] Under normal conditions, a pair of swing arms 5 rotate around their axis and move towards the guide roller 1 under the elastic potential energy of the spring plates 6. The rubber pads 9 on their inner walls adhere to the outer wall of the guide roller 1, forming a closed clamping state. The friction of the rubber pads 9 enhances the clamping stability, achieving stable clamping and limiting of the support 3. When it is necessary to adjust the position on the guide roller 1 according to the material size, the end of the swing arm 5 with the guide rod 7 is pried open, and an external force is applied to the swing arm 5 to make it rotate. The spring plates 6 between the pair of swing arms 5 deform with the rotation of the swing arms and store elastic potential energy. The swing arms 5 open and move away from the guide roller 1, and can slide on the guide roller 1 to adjust the position. After adjusting to the designated position, the swing arms 5 are released. When the external force is removed, the spring plates 6 release the stored elastic potential energy, driving the swing arms 5 to rotate in the opposite direction to reset. The guide rod 7 moves back along the sliding hole 10, and the swing arms 5 close again to clamp the guide roller 1, restoring the stable limiting state.

[0021] This application utilizes the coordinated operation of the bracket 3, the limiting plate 4, the swing arm 5, and the elastic component to form a guiding assembly on the guide roller 1. This assembly can precisely limit the side of the die-cut material, guiding it smoothly along a preset path through the guide roller 1 and preventing material conveying deviation. Compared to the conventional screw-twisting structure of current limiting devices, this design is more convenient to operate, and the elastic clamping can automatically compensate for errors and resist vibration, making it highly practical.
