Description

Technical Field

[0001] This utility model relates to the field of foam adhesive patch processing technology, specifically a foam adhesive patch shaping and cutting device. Background Technology

[0002] Foam adhesive bonding is a composite material made by coating foam as a base material with adhesive on both sides or one side. It is widely used in electronic and electrical products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, computer and peripheral equipment, automotive parts, audio-visual equipment, toys, cosmetics, etc.

[0003] A search revealed a utility model patent with Chinese patent publication number CN216890784U, which discloses a foam adhesive with positioning holes, including a foam adhesive assembly. The foam adhesive assembly includes a foam adhesive body, and a protective component is provided on one side of the foam adhesive body. The protective component includes a heavy release film, which is disposed on one side of the foam adhesive body and has positioning holes. The protective component also includes a handle, which is disposed on the top of the heavy release film.

[0004] As mentioned above, after the foam adhesive is produced, it often needs to be processed into the corresponding shape. However, the foam adhesive parts are prone to deformation during the cutting process due to the softness and high elasticity of the material, which may result in uneven edges of the processed products, affecting product quality and leaving room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a foam adhesive patch shaping and cutting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foam adhesive patch shaping and cutting device, comprising a base plate and a mounting plate, the mounting plate being located directly above the base plate, a bracket being fixedly connected to the top outer wall of the base plate, a vertically arranged cylinder being fixedly connected to the top outer wall of the bracket, the output end of the cylinder being fixedly connected to the top outer wall of the mounting plate, a cutting assembly being provided on the mounting plate, the cutting assembly comprising four guide rods slidably connected inside the mounting plate, a common connecting ring being fixedly connected to one bottom end of each of the four guide rods, a spring being sleeved on the outside of each of the four guide rods, a pressure ring being slidably connected inside the connecting ring, the connecting ring and the pressure ring sharing two connecting assemblies, two connecting rods being fixedly connected to the top outer wall of the pressure ring, a common pressure plate being fixedly connected to one end of each of the two connecting rods, the bottom wall of the pressure plate being at the same level as the bottom wall of the pressure ring, and a cutting structure being provided on the top of the pressure ring.

[0007] The above technical solution allows for the pressing of the part to be cut before the foam adhesive patch is cut, leaving only space for the cutter to cut. This effectively prevents the foam from deforming and causing uneven product edges. The pressure ring first contacts the foam adhesive patch. As the mounting plate continues to move, the first spring is pressed and begins to contract. Its reaction force acts on the foam adhesive through the connecting ring and the pressure ring. The foam adhesive is compressed, making the device stable and preventing it from moving during cutting. Subsequently, the mounting plate and the top wall of the guide rod are attached, the elastic force of the second spring is overcome and it begins to shorten. The cutter then moves out of the gap between the pressure ring and the pressure plate, thus completing the cutting process.

[0008] As a further preferred embodiment of this technical solution, the cutting structure includes two limiting rods fixedly connected to the top of the pressure ring, the two limiting rods being slidably connected to the same cutter, the cutter being located between the pressure plate and the pressure ring, and a spring being sleeved on the outside of each of the two limiting rods, and a contact element being fixedly connected to the top of the cutter.

[0009] As a further preferred embodiment of this technical solution, the contact element includes an extension frame fixedly connected to the outer wall of the top of the cutter, the extension frame being located above one of the two connecting rods.

[0010] As a further preferred embodiment of this technical solution, the connecting assembly includes two limiting sleeves fixedly connected to the outer wall of one side of the connecting ring. A mounting frame is fixedly connected to the outer wall of one side of the pressure ring. A limiting groove is provided on the outer wall of both ends of the mounting frame. A horizontally arranged connecting rod II is slidably connected inside the two limiting grooves. The ends of the two connecting rod II that are far apart from each other are slidably connected to the two limiting sleeves respectively. A horizontally arranged spring III is fixedly connected to the inner wall of the ends of the two limiting grooves that are close to each other. The two spring IIIs are fixedly connected to the two connecting rod IIs respectively. The two connecting rod IIs are fixedly connected to the same driving component.

[0011] To achieve the above technical solution, if the shape of the foam adhesive to be cut changes, simply grasp the flexible pull rod and pull it outward. The flexible pull rod will cause the two interconnected connecting rods 2 to overcome the elastic force of the spring 3 and move closer to each other. Then, the two connecting rods 2 will move out of the limiting sleeve. At this time, the pressure ring will no longer be restricted in the vertical direction. Pulling it downward will complete the disassembly. During installation, pull the two flexible pull rods to make them move away from each other and slide the new pressure ring inside the connecting ring. Finally, release the flexible pull rod to complete the fixation.

[0012] As a further preferred embodiment of this technical solution, the driving component includes a flexible pull rod fixedly connected to the outer wall of one side of the two connecting rods, and the two ends of the flexible pull rod are respectively located at the ends of the two connecting rods that are close to each other.

[0013] As a further preferred embodiment of this technical solution, the edges of the two connecting rods at opposite ends are both provided with rounded corners.

[0014] This utility model provides a foam adhesive patch shaping and cutting device, which has the following beneficial effects: (1) By setting a cutting component, this utility model can press the part to be cut before the foam adhesive patch is cut, leaving only the cutting space for the cutter, effectively avoiding the deformation of the foam and the unevenness of the product edge. The pressure ring will first contact the foam adhesive patch. As the mounting plate continues to move, the spring one is pressed and begins to contract. Its reaction force will act on the foam adhesive through the connecting ring and the pressure ring. The foam adhesive is compressed, making the device stable and not moving with the cutting. Then the mounting plate and the top wall of the guide rod are attached, the elastic force of the spring two is overcome and begins to shorten, and the cutter will move out of the gap between the pressure ring and the pressure plate, thus completing the cutting work.

[0015] (2) By setting up a connecting component, if the shape of the foam adhesive to be cut changes, simply grab the flexible pull rod and pull it outward. The flexible pull rod will drive the two interconnected connecting rods two to overcome the elastic force of the spring three and move closer to each other. Then the two connecting rods two will move out of the limiting sleeve. At this time, the pressure ring will no longer be restricted in the vertical direction. Pulling it down will complete the disassembly. When installing, pull the two flexible pull rods to make them move away from each other and slide the new pressure ring inside the connecting ring. Finally, release the flexible pull rod to complete the fixation. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] This utility model provides a technical solution: such as Figure 1-3 As shown, in this embodiment, the foam adhesive patch shaping and cutting device includes a base plate 1 and a mounting plate 2. The mounting plate 2 is located directly above the base plate 1. A bracket 3 is fixedly connected to the top outer wall of the base plate 1.

A pressure ring 503 is slidably connected inside the connecting ring 502. The connecting ring 502 and the pressure ring 503 are provided with two connecting assemblies 6. Two connecting rods 506 are fixedly connected to the top outer wall of the pressure ring 503. The ends of the two connecting rods 506 that are close to each other are fixedly connected to the same pressure plate 505. The bottom wall of the pressure plate 505 and the bottom wall of the pressure ring 503 are at the same level. The top of the pressure ring 503 is provided with a cutting structure.

[0019] The cutting structure includes two limiting rods 507 fixedly connected to the top of the pressure ring 503. The two limiting rods 507 are slidably connected to the same cutter 508. The cutter 508 is located between the pressure plate 505 and the pressure ring 503. A spring 509 is sleeved on the outside of each of the two limiting rods 507. A contact element is fixedly connected to the top of the cutter 508.

[0020] The contact element includes an extension bracket 510 fixedly connected to the top outer wall of the cutter 508, the extension bracket 510 being located above the two connecting rods 506.

[0021] The external valve is opened to allow air to enter the cylinder 4, causing the output end of the cylinder 4 to move downwards. The mounting plate 2 and the entire cutting assembly 5 will move synchronously with the output end of the cylinder 4. The pressure ring 503 will first contact the foam adhesive. As the mounting plate 2 continues to move, the spring 504 is pressed and begins to contract. Its reaction force will act on the foam adhesive through the connecting ring 502 and the pressure ring 503. The foam adhesive is compressed, making the device stable and preventing it from moving during cutting. Subsequently, the mounting plate 2 and the top wall of the guide rod 501 are attached, the elasticity of the spring 509 is overcome and it begins to shorten. The cutter 508 will then move out of the gap between the pressure ring 503 and the pressure plate 505, thus completing the cutting work.

[0022] like Figure 2 and Figure 4As shown, the connecting assembly 6 includes two limiting sleeves 604 fixedly connected to the outer wall of one side of the connecting ring 502. A mounting frame 601 is fixedly connected to the outer wall of one side of the pressure ring 503. A limiting groove 602 is opened on the outer wall of both ends of the mounting frame 601. A horizontally set connecting rod 603 is slidably connected inside the two limiting grooves 602. The ends of the two connecting rods 603 that are far apart from each other are slidably connected to the two limiting sleeves 604 respectively. A horizontally set spring 606 is fixedly connected to the inner wall of the ends of the two limiting grooves 602 that are close to each other. The two springs 606 are fixedly connected to the two connecting rods 603 respectively. The two connecting rods 603 are fixedly connected to the same driving component.

[0023] The driving component includes a flexible pull rod 605 fixedly connected to the outer wall of one side of the two connecting rods 603, and the two ends of the flexible pull rod 605 are respectively located at the ends of the two connecting rods 603 that are close to each other.

[0024] If the shape of the foam adhesive to be cut changes, simply grasp the flexible pull rod 605 and pull it outward. The flexible pull rod 605 will drive the two interconnected connecting rods 603 to overcome the elastic force of the spring 606 and move closer to each other. Then the two connecting rods 603 will move out of the limiting sleeve 604. At this time, the pressure ring 503 will no longer be restricted in the vertical direction. Pulling it downward will complete the disassembly. During installation, pull the two flexible pull rods 605 to make them move away from each other, and slide the new pressure ring 503 into the connecting ring 502. Finally, release the flexible pull rod 605 to complete the fixation.

[0025] like Figure 4 As shown, the edges of the two connecting rods 603 at opposite ends are rounded, which makes the process of inserting the connecting rod 603 into the limiting sleeve 604 more forgiving.

[0026] This utility model provides a foam adhesive patch shaping and cutting device, the specific working principle of which is as follows: When the device is working, the external valve is opened to ventilate the cylinder 4. The output end of the cylinder 4 is pushed out and moves downward. The mounting plate 2 and the entire cutting assembly 5 will move synchronously with the output end of the cylinder 4. The pressure ring 503 will first contact the foam adhesive. As the mounting plate 2 continues to move, the spring 504 is pressed and begins to contract. Its reaction force will act on the foam adhesive through the connecting ring 502 and the pressure ring 503. The foam adhesive is compressed, making the device stable and preventing it from moving during cutting. Subsequently, the mounting plate 2 and the top wall of the guide rod 501 are attached, the elasticity of the spring 509 is overcome and it begins to shorten. The cutter 508 will then move out of the gap between the pressure ring 503 and the pressure plate 505, thereby completing the cutting work.

[0027] If the shape of the foam adhesive to be cut changes, simply grasp the flexible pull rod 605 and pull it outward. The flexible pull rod 605 will drive the two interconnected connecting rods 603 to overcome the elastic force of the spring 606 and move closer to each other. Then the two connecting rods 603 will move out of the limiting sleeve 604. At this time, the pressure ring 503 will no longer be restricted in the vertical direction. Pulling it downward will complete the disassembly. During installation, pull the two flexible pull rods 605 to make them move away from each other, and slide the new pressure ring 503 into the connecting ring 502. Finally, release the flexible pull rod 605 to complete the fixation.
