Description

Technical Field

[0001] This utility model relates to the field of film roll stamping technology, and in particular to a film roll stamping assembly. Background Technology

[0002] Film roll stamping assemblies are key equipment in film product processing, widely used in packaging, electronics, and new energy fields. Through the precise coordination of upper and lower dies, they continuously stamp rolls of film material into the desired individual sheet products. This assembly typically includes a bottom die and a top die, working in conjunction with a winding and unwinding mechanism to achieve stamping. Its core objective is to achieve efficient, stable, and consistent stamping operations to meet the high requirements of downstream automated production for product specification consistency.

[0003] A search revealed that patent CN222360309U discloses a film roll punching assembly, which consists of a lower punching module, an upper punching module, a telescopic part, and a guide part to realize the punching process of film rolls. It provides a punching assembly with good feeding and unloading stability. By using pneumatic pressurization, the punched film can be quickly discharged, which can avoid the film from sticking to the template due to its own stickiness or surface tension.

[0004] However, the above-mentioned device has the following drawbacks: First, to prevent the punched sheets from sticking together, an external air source is required to punch the sheets off the template, which not only adds extra equipment but also makes the template structure difficult to process; Second, each set of two guiding mechanisms in this component is adjusted independently, and cannot move simultaneously to achieve centering. The adjustment is not accurate enough and is cumbersome. When the roll material moves between the guiding components, friction easily occurs on the sides, causing the roll material to deform. Therefore, further improvements are needed. To this end, we propose a film roll punching assembly. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a thin film roll stamping assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a film roll punching assembly, comprising a base plate, a support plate and a top plate fixed on the upper surface of the base plate by a plurality of support rods, the support plate being located between the top plate and the base plate, a plurality of slits being provided in the middle of the support plate, and side grooves being provided on both sides of the bottom end of each slit, a brush being fixed to the inner wall of the side groove, and strip-shaped openings being provided on both sides of the support plate, with limit components provided inside the strip-shaped openings and on the lower surface of the support plate, a cylinder being fixed on the upper surface of the top plate, a lifting plate being fixed to the telescopic end of the bottom of the cylinder, a punching module being installed on the lower surface of the lifting plate and directly above each slit, and clamping components being installed on the lower surface of the lifting plate and on both sides of the punching module.

[0007] Furthermore, the thickness of the punching module is greater than the cut height, and the bristles of the brush extend below the cut.

[0008] Furthermore, a guide rod is fixed to the upper surface of the lifting plate, and the guide rod passes through the top plate and is slidably connected to the top plate.

[0009] Furthermore, the clamping assembly includes a diagonal bar hinged to the lower surface of the lifting plate, a second U-shaped plate fixed to the bottom end of the diagonal bar, a pressure roller rotatably connected inside the second U-shaped plate, and a spring fixedly connected to the middle part of the diagonal bar and the lower surface of the lifting plate.

[0010] Furthermore, the limiting component includes two vertical plates fixed to the lower surface of the support plate, and the two vertical plates are located on both sides of the strip-shaped opening. A bidirectional lead screw is rotatably connected between the two vertical plates via a bearing. Two symmetrical internal thread blocks are rotatably connected to the surface of the bidirectional lead screw via threads. Two symmetrical first U-shaped plates are fixed to the upper surface of the two internal thread blocks, and a limiting shaft is rotatably connected inside the first U-shaped plates.

[0011] Furthermore, a hexagonal nut is fixedly connected to one end of the bidirectional lead screw.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, this utility model includes a base plate, a support plate, a brush, a cylinder, a lifting plate, a punching module, and a clamping assembly. When the cylinder drives the lifting plate and the punching module to descend for punching, the punching module completely passes through the cut. When the cylinder drives the lifting plate and the punching module to rise and reset, the brush scrapes off the sheet material attached to the lower surface of the punching module, eliminating the need for an additional air source for feeding. Secondly, the clamping assembly is used to press the roll material on both sides of the cut to ensure stable punching.

[0014] 2. In use, this utility model is equipped with a support plate and two sets of limiting components. The limiting components can drive the two limiting shafts to move closer or further apart by rotating the bidirectional screw, thereby adjusting the distance between the two limiting shafts to achieve better centering and adapt to different widths of coiled material. The adjustment is faster and more convenient. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a film roll punching assembly is disclosed, including a base plate 1. A support plate 2 and a top plate 9 are fixed to the upper surface of the base plate 1 by multiple support rods. The support plate 2 is located between the top plate 9 and the base plate 1. Multiple cuts 21 are provided in the middle of the support plate 2, and side grooves 22 are provided on both sides of the bottom end of each cut 21. A brush 3 is fixed to the inner wall of the side groove 22. A strip-shaped opening 23 is provided on both sides of the support plate 2. A limit component 4 is provided inside the strip-shaped opening 23 and on the lower surface of the support plate 2. A cylinder 5 is fixed to the upper surface of the top plate 9. A lifting plate 6 is fixed to the telescopic end of the bottom of the cylinder 5. A punching module 7 is installed on the lower surface of the lifting plate 6 and directly above each cut 21. A clamping component 8 is installed on the lower surface of the lifting plate 6 and on both sides of the punching module 7.

[0024] The thickness of the punching module 7 is greater than the height of the cut 21, and the bristles of the brush 3 extend below the cut 21.

[0025] The lifting plate 6 can be raised and lowered by the extension and retraction of the cylinder 5. The punching module 7 at the bottom of the lifting plate 6 passes through the cut 21 to punch the roll material. During the punching process, the punched sheet will pass through the brush 3. Then, when the cylinder 5 drives the lifting plate 6 to rise and reset, the brush 3 will scrape off the sheet material on the lower surface of the punching module 7 to prevent the sheet material from sticking.

[0026] A guide rod is fixed on the upper surface of the lifting plate 6, and the guide rod passes through the top plate 9 and is slidably connected to the top plate 9.

[0027] The guide rod can increase the stability of the movement of the lifting plate 6.

[0028] The clamping assembly 8 includes a diagonal bar 81 hinged to the lower surface of the lifting plate 6. A second U-shaped plate 82 is fixed to the bottom end of the diagonal bar 81. A pressure roller 83 is rotatably connected inside the second U-shaped plate 82. A spring 84 is fixedly connected to the middle part of the diagonal bar 81 and the lower surface of the lifting plate 6.

[0029] As the lifting plate 6 descends, it will drive the pressing assembly 8 to descend synchronously. In this embodiment, the bottom height of the pressure roller 83 is lower than that of the punching module 7. Therefore, the pressure roller 83 will first contact the surface of the roll material. As the lifting plate 6 continues to descend, the inclined rod 81 will rotate away from the cut 21, and the pressure roller 83 will roll on the surface of the roll material. Then, the two pressing assemblies 8 will push the roll material on both sides of the cut 21 to the sides, so that the roll material unfolds and avoids the roll material from warping. During this process, the spring 84 is compressed. When the lifting plate 6 moves up and resets, the spring 84 pushes the inclined rod 81 and the pressure roller 83 to reset.

[0030] The limiting component 4 includes two vertical plates 41 fixed to the lower surface of the support plate 2, and the two vertical plates 41 are located on both sides of the strip opening 23. A bidirectional lead screw 42 is rotatably connected between the two vertical plates 41 through a bearing. Two symmetrical internal thread blocks 43 are rotatably connected to the surface of the bidirectional lead screw 42 through a thread. Two symmetrical first U-shaped plates 44 are fixed to the upper surface of the two internal thread blocks 43, and a limiting shaft 45 is rotatably connected inside the first U-shaped plates 44.

[0031] One end of the double-ended lead screw 42 is fixedly connected to a hexagonal nut.

[0032] When punching sheets of different widths of coil material, rotating the hexagonal nut drives the double-acting screw 42 to rotate. The double-acting screw 42 drives the internal thread block 43 and the two first U-shaped plates 44 to move closer and further apart, thereby adjusting the distance between the two limiting shafts 45 so that the coil material can just pass between the two limiting shafts 45. Since the limiting shafts 45 can rotate, the friction of the coil material is reduced, preventing deformation of the coil material.

[0033] This component is used in conjunction with the roll winding and unwinding mechanism, which is existing technology. The winding and unwinding mechanism and cylinder 5 use the same control system. Both the control system and the winding and unwinding mechanism use existing technology, which will not be described in detail here.

[0034] Working principle: First, the bidirectional lead screw 42 of the limiting component 4 is rotated according to the width of the roll material, driving the two internal threaded blocks 43 to move the first U-shaped plate 44 and the limiting shaft 45 in opposite directions to adjust to a suitable distance. After the roll material passes between the two limiting shafts 45 and is placed on the support plate 2, the cylinder 5 is activated, driving the lifting plate 6 to move downward along the guide rod. During the descent, the pressure roller 83 of the pressing component 8 first contacts the surface of the roll material. As the lifting plate 6 continues to descend, the spring 84 is compressed, driving the inclined rod 81 to push the pressure roller 83 to roll to both sides, flattening the roll material. Then, the punching module 7 passes through the cut 21 to complete the punching, and the punched sheet passes through the brush 3. After the punching is completed, the cylinder 5 drives the lifting plate 6 to rise and reset. At this time, the brush 3 automatically scrapes off the sheet material adhering to the lower surface of the punching module 7, while the pressing component 8 resets synchronously under the restoring force of the spring 84, thus completing one punching operation cycle.

[0035] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
