Description

Technical Field

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

[0002] Foam is a material made by foaming plastic particles. Foam is divided into PU foam, antistatic foam, conductive foam, etc. The corresponding specifications are selected according to different application scenarios. Foam has a series of characteristics such as elasticity, light weight, quick pressure-sensitive fixation, and ease of use. During the processing, foam may have irregularities, defects, or other non-standard parts. Trimming can remove these unqualified parts, thereby improving the quality of the final product. Trimming can also ensure the overall consistency of the foam.

[0003] In the existing technology, a special edge-cutting device is required to cut foam. The foam to be cut is placed on the worktable of the edge-cutting device. The worktable is usually covered with an anti-slip mat to increase friction and prevent the foam from sliding. However, the anti-slip mat can cause the foam to shift or deform during cutting. In particular, if the surface of the anti-slip mat or sandpaper mat is uneven, it will affect the accuracy of the cutting, resulting in uneven cut edges and reduced edge-cutting precision. Therefore, an edge-cutting device for foam processing is proposed to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a cutting device for foam processing, which has the advantage of good cutting effect. It solves the problem that anti-slip mats can cause foam to shift or deform during cutting, especially when the surface of the anti-slip mat or sandpaper mat is uneven, which will affect the cutting accuracy, resulting in uneven cutting edges and reduced cutting precision.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cutting device for foam processing, comprising a device body, wherein a cutting blade for cutting foam is provided on the device body, and two limiting mechanisms for fixing foam are symmetrically arranged on the device body.

[0006] The limiting mechanism includes two first support plates mounted on the device body, a shaft disposed on one side of the two first support plates, a drive module mounted on the end of the shaft away from the first support plate, a positioning ring disposed on the piston rod of the drive module, a positioning rod rotatably connected inside the positioning ring, a connecting piece disposed on the positioning rod, and a pressure plate disposed on the side of the connecting piece away from the positioning rod.

[0007] Furthermore, the first support plates on the front and rear sides are parallel to each other, and the shaft is rotatably connected to the first support plate through a bearing.

[0008] Furthermore, the positioning ring has a positioning hole that fits with the positioning rod with a clearance, and the positioning rod is rotatably connected in the positioning hole.

[0009] Furthermore, the device body is equipped with two parallel second support plates, and a rotating rod is rotatably connected between the opposite sides of the second support plates on the front and rear sides via a bearing.

[0010] Furthermore, the pressure plate is located between the opposite sides of the second support plates on both the front and rear sides.

[0011] Furthermore, a through hole is formed on the pressure plate for the rotating rod to pass through, and the through hole is clearance-fitted with the rotating rod.

[0012] Furthermore, a rubber pad is provided on the pressure plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This foam processing edge-cutting device incorporates a limiting mechanism. By including a drive module, a positioning ring, and connecting plates, when the drive module is activated and its piston rod lengthens, the positioning ring rotates the connecting plates. The rotation of the connecting plates lifts the pressure plates, allowing the foam to be edge-cut to be placed. Then, the piston rod shortens, and the rotation of the connecting plates presses down the pressure plates. The pressure plates on both sides hold the foam in place. Finally, the drive module is deactivated, and the foam to be edge-cut is fixed to the device body, preventing displacement during edge cutting and improving cutting accuracy. This solution addresses the problem of anti-slip mats causing foam displacement or deformation during cutting, especially when the surface of the anti-slip mat or sandpaper mat is uneven, which affects cutting accuracy, leading to uneven cut edges and reduced edge-cutting precision.

[0020] 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.

[0021] Please see Figure 1-4 The foam processing edge cutting device in this embodiment includes a device body 1, a cutting blade 2 for cutting foam is provided on the device body 1, and two limiting mechanisms 3 for fixing foam are symmetrically arranged on the device body 1.

[0022] It should be noted that the device body 1 is a common edge trimming machine in the prior art, and the usage method and working principle of the device body 1 are well known to those skilled in the art of foam processing, and will not be elaborated further in this article.

[0023] The limiting mechanism 3 includes two first support plates 301 mounted on the device body 1, a shaft 302 disposed on one side of the two first support plates 301, a drive module 303 mounted on the end of the shaft 302 away from the first support plates 301, a positioning ring 304 disposed on the piston rod of the drive module 303, a positioning rod 305 rotatably connected inside the positioning ring 304, a connecting piece 306 disposed on the positioning rod 305, and a pressure plate 307 disposed on the side of the connecting piece 306 away from the positioning rod 305.

[0024] In application, after placing the foam to be trimmed on the device body 1, the drive module 303 is activated, causing the piston rod of the drive module 303 to shorten, which drives the positioning ring 304 to move. The positioning rod 305 rotates within the positioning ring 304, and the positioning rod 305 drives the connecting piece 306 to rotate. The connecting piece 306 drives the pressure plate 307 to press down. After the pressure plate 307 presses down the foam to be trimmed, the rotating cutting blade 2 trims the foam by moving left and right. After trimming, the piston rod of the drive module 303 is extended, and the positioning rod 305 drives the connecting piece 306 to rotate. The connecting piece 306 lifts the pressure plate 307, and the trimmed foam can be removed.

[0025] Preferably, the drive module 303 in this application is a cylinder. The cylinder can provide smooth and adjustable linear motion. The uniform extension and retraction of the piston rod is very suitable for application scenarios that require precise pressure control. When driving the pressure plate 307, the cylinder can ensure that the pressure plate 307 rotates at a uniform speed, so that the foam is uniformly compressed or loosened, avoiding unstable operation caused by uneven speed.

[0026] Furthermore, the first support plates 301 on the front and rear sides are parallel to each other, and the shaft 302 is rotatably connected to the first support plate 301 through a bearing.

[0027] Furthermore, a positioning hole is formed on the positioning ring 304 that is clearance-fitted with the positioning rod 305, and the positioning rod 305 is rotatably connected in the positioning hole.

[0028] The main body 1 of the device is equipped with two parallel second support plates, and a rotating rod is rotatably connected between the opposite sides of the front and rear second support plates through a bearing.

[0029] The pressure plate 307 is located between the opposite sides of the second support plates on both the front and rear sides.

[0030] The pressure plate 307 has a through hole for the rotating rod to pass through. The through hole and the rotating rod are fitted with a clearance fit, and the pressure plate 307 is fixedly connected to the rotating rod.

[0031] It is known that a rubber pad is provided on the pressure plate 307. The rubber pad is soft and protects the foam when the foam on the device body 1 is trimmed, preventing the foam from being indented.

[0032] It is understood that the piston rod of the control unit drive module 303 extends and retracts at a constant speed, so that the pressure plate 307 can rotate at a constant speed, thereby pressing and releasing the foam on the device body 1; the control unit and its working principle are well known to those skilled in the art, and will not be described in this embodiment.

[0033] All standard parts used in this application can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0034] The working principle of the above embodiments is as follows:

[0035] During the foam processing, when using the device body 1 to trim the foam, after placing the foam to be trimmed on the device body 1, the drive module 303 is activated, causing the piston rod of the drive module 303 to shorten, which in turn moves the positioning ring 304. The positioning rod 305 rotates within the positioning ring 304, and the positioning rod 305 drives the connecting piece 306 to rotate. The connecting piece 306 then drives the pressure plate 307 to press down. After the pressure plate 307 presses down the foam to be trimmed, the rotating cutting blade 2 trims the foam by moving left and right. After trimming, the piston rod of the drive module 303 is extended, and the positioning rod 305 drives the connecting piece 306 to rotate. The connecting piece 306 then lifts the pressure plate 307, allowing the trimmed foam to be removed.
