Description

Technical Field

[0001] This utility model relates to the field of circular die-cutting technology, and more specifically, to an asynchronous material collection auxiliary device for circular die-cutting. Background Technology

[0002] Circular die-cutting refers to cutting materials using a circular cutter. It is widely used in packaging printing, mobile phones, computers, LCD monitors, digital cameras, LCD backlights, and other fields. For processes where the circular die operates asynchronously and requires waste removal, the normal operating route and the asynchronous operating route do not travel at the same frequency during production. That is, the normal operating route travels continuously, while the asynchronous operating route follows for a short distance, then pauses briefly, and then continues following, repeating this cycle. This is the operating principle of asynchronous processes. However, during operation: because the asynchronous operating route pauses briefly, as the waste material gradually increases in size during winding, two tension issues arise. If the tension is too low, the waste material cannot be pulled up, and it follows the normal operating route, resulting in defective products. If the tension is too high, the waste material breaks, also following the normal operating route, resulting in defective products. If the waste material breaks due to excessive tension or is pulled into the next process due to insufficient tension, it increases the time required for manual machine adjustment caused by the breakage of asynchronous waste material, resulting in high labor costs and reduced production efficiency. Based on this, this utility model designs an asynchronous material collection auxiliary device for circular die cutting to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide an asynchronous material receiving auxiliary device for circular die cutting to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An asynchronous material receiving auxiliary device for circular die-cutting includes a base plate, a front through rod, a rear through rod, a middle through rod, and a slide block. The front and rear through rods are rotatably mounted on the front and rear sides of the upper section of the base plate, respectively. Two guide rails are symmetrically fixed to the lower section of the base plate by a first bolt. The opposite end faces of the base plate and the slide block are in contact. The slide block is slidably connected between the two guide rails. An upper protruding post is fixedly mounted through the slide block. A side plate is fixedly mounted on the back side of the base plate by a second bolt. A lower protruding post is fixedly mounted on the side plate and penetrates the end face of the base plate. A spring connects the upper and lower protruding posts. The middle through rod is rotatably mounted on the outer end of the slide block.

[0006] As a preferred embodiment of this utility model, a U-shaped stop is fixedly installed on the base plate by a third bolt, and the lower protruding post is located on the inner side of the U-shaped stop.

[0007] As a preferred technical solution of this utility model, the end face of the base plate is provided with a guide slide, and the upper protruding post is slidably connected to the guide slide.

[0008] As a preferred embodiment of this utility model, the number of springs is two, and the two springs are distributed on the front and rear sides of the slide.

[0009] As a preferred technical solution of this utility model, the end face of the base plate is provided with a plurality of hole groups at intervals, and the hole group is composed of two mounting holes arranged laterally at intervals.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention winds the waste material around the front through rod, then down the middle through rod, and then up the rear through rod before winding it up. During a brief pause in the asynchronous operation, the tension at the winding point is applied to the middle through rod, pulling it upwards. Upon resumption of the asynchronous operation, the waste material is immediately compressed by the spring attached to the middle through rod, thus providing a constant pressure auxiliary effect during the winding process. This effectively prevents the waste material from breaking due to excessive tension or being pulled into the next process step due to insufficient tension. It saves time spent manually adjusting the machine due to breakage of the asynchronous waste material, reducing labor costs and improving production efficiency. Attached Figure Description

[0017] 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.

[0018] like Figures 1 to 4 As shown, this utility model provides an asynchronous material receiving auxiliary device for circular die-cutting, including a base plate 1, a front through rod 2, a rear through rod 3, a middle through rod 4, and a slide block 6. The front through rod 2 and the rear through rod 3 are rotatably installed on the front and rear sides of the upper section of the base plate 1, respectively. Two guide rails 5 are symmetrically fixedly installed on the lower section of the base plate 1 by a first bolt 101. The opposite end faces of the base plate 1 and the slide block 6 are in contact. The slide block 6 is slidably connected between the two guide rails 5. An upper protrusion 601 is fixedly installed through the slide block 6. A side plate 7 is fixedly installed on the back side of the base plate 1 by a second bolt 102. A lower protrusion 701 is fixedly installed on the side plate 7. The lower protrusion 701 passes through the end face of the base plate 1. A spring 8 is connected between the upper protrusion 601 and the lower protrusion 701. The middle through rod 4 is rotatably installed on the outer end of the slide block 6.

[0019] Among them, such as Figure 1 As shown, a U-shaped stop 9 is fixedly installed on the base plate 1 by the third bolt 103. The lower protrusion 701 is located on the inner side of the U-shaped stop 9, which achieves the purpose of preventing the spring 8 from falling off.

[0020] Among them, such as Figure 1 As shown, the end face of the base plate 1 is provided with a guide slide 104, and the upper protrusion 601 is slidably connected to the guide slide 104, which can further guide the slide 6.

[0021] Among them, such as Figure 4 As shown, there are two springs 8, which are distributed on the front and rear sides of the slide block 6.

[0022] Among them, such as Figure 3 As shown, the end face of the base plate 1 is provided with a number of hole groups 105 at intervals. The hole group 105 is composed of two mounting holes arranged laterally at intervals, which can fasten the base plate 1 to the circular die-cutting machine.

[0023] The working principle of this utility model:

[0024] The waste material is wound around the front through rod 2, then down around the middle through rod 4, and then up around the rear through rod 3. The waste material is then wound up. During the brief pause in the asynchronous operation, the tension at the waste material winding point is applied to the middle through rod 4, pulling it upward. After the asynchronous operation resumes, the waste material is immediately compressed by the spring 8 attached to the middle through rod 4, thus playing a role in maintaining constant pressure during the waste material winding process. This effectively prevents the waste material from breaking due to excessive tension or being wound into the next process due to insufficient tension, saving the time required for manual machine adjustment caused by the breakage of asynchronous waste material.
