Description

Technical Field

[0001] This utility model belongs to the field of silicone foam technology, specifically relating to a silicone foam positioning and cutting fixture. Background Technology

[0002] The silicone foam positioning and cutting fixture is a device used for precise cutting of silicone foam. It uses positioning clamping plates, guide frames and other positioning components to fix the silicone foam in a specific position and direction through mechanical clamping and guiding, so as to ensure that the silicone foam will not shift or shake during the cutting process, thereby ensuring the cutting accuracy.

[0003] Due to the material properties of silicone foam and the need for convenient transportation, roll transportation has become a common practice in the industry. By winding the silicone foam onto a roll, the space occupied during transportation can be greatly reduced. However, when silicone foam is transported in rolls, the winding state will cause the material to be under bending stress for a long time. After being unwound, it is very easy to cause natural bending and warping due to stress release. This unstable shape directly interferes with the accuracy of subsequent cutting processes.

[0004] Existing silicone foam positioning and cutting fixtures focus on the edge area of ​​the material, which can only limit the overall displacement of the silicone foam, but cannot solve the problem of suspension caused by bending in the middle and non-edge areas of the material. Because of bending, the silicone foam cannot fully fit the cutting table, and cutting size deviations are prone to occur during the cutting process. Utility Model Content

[0005] The purpose of this utility model is to provide a silicone foam positioning and cutting fixture to solve the problem that the silicone foam positioning and cutting fixture proposed in the background art focuses on the edge area of ​​the material, can only restrict the overall displacement of the silicone foam, but cannot solve the problem of suspension caused by bending in the middle and non-edge areas of the material. The silicone foam cannot fully fit the cutting table surface due to bending, and the cutting size deviation is prone to occur during the cutting process.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

Detailed Implementation

[0041] 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.

[0042] Please see Figures 1-5A silicone foam positioning and cutting fixture includes a cutting table 100, and further includes: two control seats 300 symmetrically arranged on the cutting table 100; two positioning plates 400 respectively installed on the two control seats 300; a mounting groove 101 formed on the top of the cutting table 100; a ventilation plate 102 installed in the mounting groove 101 and flush with the cutting table 100; and a fan 200 installed at the bottom of the cutting table 100, with the air inlet of the fan 200 connected to the mounting groove 101.

[0043] In this embodiment, the symmetrically arranged control seat 300 and positioning plate 400 achieve precise clamping of the two edges of the silicone foam, effectively limiting the lateral displacement of the material. The positioning plate 400 can move laterally on the control seat 300, and the distance between the two positioning plates 400 can be quickly adjusted to adapt to silicone foam of different specifications, improving the versatility of the tooling. The fan 200 forms a uniform negative pressure environment through the mounting groove 101 and the mesh ventilation plate 102, adsorbing the silicone foam as a whole onto the surface of the cutting table 100, completely solving the problem of traditional tooling only being able to position the edges, resulting in the middle being suspended and warped. The ventilation plate 102 adopts a mesh design flush with the table surface, which avoids scratching the material surface while ensuring the adsorption effect, and is suitable for highly sensitive silicone foam products.

[0044] A support plate 103 is installed in the mounting groove 101, and a ventilation plate 102 is located on top of the support plate 103; both the ventilation plate 102 and the support plate 103 are mesh structures.

[0045] The support plate 103 provides stable support for the ventilation plate 102, preventing the ventilation plate 102 from deforming due to the pressure or negative pressure adsorption of the silicone foam, ensuring that the ventilation plate 102 is flush with the cutting table 100, and thus maintaining the flatness of the silicone foam placement. The mesh structure of the ventilation plate 102 and the support plate 103 has a large number of hollow areas, which form airflow channels. When the fan 200 is working, the airflow can pass through the mesh of the ventilation plate 102 and the mesh of the support plate 103 in sequence, and then enter the fan 200 through the ventilation holes on the bottom wall of the mounting groove 101. During this process, the silicone foam above the ventilation plate 102 will be tightly pressed onto the ventilation plate 102 under the action of atmospheric pressure, achieving adsorption and positioning. Moreover, since the hollow areas of the mesh structure are relatively evenly distributed, the negative pressure formed by the airflow is also relatively even, so that the adsorption force on each part of the silicone foam is consistent, thus ensuring that it can be flatly attached to the ventilation plate 102.

[0046] The cutting table 100 includes: two moving slots 104, which are located on the top of the cutting table 100, and two control seats 300 are respectively installed in the two moving slots 104; two power sources 301, which are respectively installed in the two moving slots 104, and the power shaft of the power source 301 is connected to the corresponding control seat 300; the power source 301 is a linear motor, or a cylinder may be used.

[0047] The power source 301 drives the control seat 300 to move within the moving groove 104, which can quickly adjust the distance between the two control seats 300, thereby changing the clamping position of the positioning plate 400 on the silicone foam, meeting diverse cutting needs, and enabling flexible and precise position adjustment of the control seat 300 and the positioning plate 400, effectively adapting to silicone foam of different widths; at the same time, the moving groove 104 guides the movement of the control seat 300, ensuring the stability and straightness of the movement of the control seat 300.

[0048] The control base 300 includes: a through hole 302, which is formed on one side of the control base 300, and a positioning plate 400 is disposed in the through hole 302; a connecting groove, which is formed on the inner wall of the through hole 302; a limiting head 303, which is installed in the connecting groove, and one end of the limiting head 303 contacts the positioning plate 400; a lead screw 304, one end of which is threadedly connected to the limiting head 303, and the other end of which passes through the connecting groove and extends to the outside of the control base 300; and a knob 305, which is disposed on the top of the control base 300, and the lead screw 304 is connected to the knob 305.

[0049] Rotating the screw 304 by the knob 305 can move the limiting head 303 within the connecting groove, thereby pushing or releasing the positioning plate 400. This allows the positioning plate 400 to move flexibly within the through hole 302, and the distance between the two positioning plates 400 can be adjusted. At the same time, the contact-type limiting between the limiting head 303 and the positioning plate 400 provides a stable clamping force for the positioning plate 400, preventing the positioning plate 400 from loosening due to vibration or material tension during the cutting process, thus ensuring positioning accuracy.

[0050] The positioning plate 400 includes: a groove 402 formed at the bottom of the positioning plate 400; a rotating plate 401 installed in the groove 402; a flattening roller 403 installed at the end of the rotating plate 401 away from the positioning plate 400; and an elastic element 404 installed between the inner wall of the groove 402 and the rotating plate 401. The elastic element 404 can be a spring sheet or a spring.

[0051] The flattening roller 403 can rotate flexibly with the rotating plate 401. During the conveying or positioning of silicone foam, it can roll against the surface of the material to flatten the wrinkles and warped parts at the edges, preventing wrinkles from entering the cutting area and affecting the cutting quality. The flattening roller 403 can effectively smooth the edges and surrounding areas of the silicone foam, while adapting to silicone foam of different thicknesses, improving the flatness of the positioning and cutting. The elastic element 404 provides continuous pressure to the rotating plate 401 and the flattening roller 403 through its own elasticity, so that the flattening roller 403 always keeps in contact with the surface of the silicone foam. When there are slight differences in the thickness of the silicone foam, the elastic element 404 can adaptively adjust the pressure by stretching and contracting, which ensures the smoothing effect without damaging the material due to excessive pressure.

[0052] The bottom wall of the mounting groove 101 has ventilation holes, and the air inlet of the fan 200 is connected to the mounting groove 101 through the ventilation holes. The cooperation between the ventilation holes and the fan 200 can provide a stable and efficient negative pressure environment within the mounting groove 101, ensuring that the silicone foam is firmly adsorbed onto the ventilation plate 102. The ventilation holes, as airflow channels between the fan 200 and the mounting groove 101, can guide the suction force generated by the fan 200 to concentrate within the mounting groove 101, enhancing the adsorption effect on the silicone foam.

[0053] The bottom of the positioning plate 400 is provided with an anti-slip layer; the anti-slip layer at the bottom of the positioning plate 400 can increase the friction between the positioning plate 400 and the silicone foam, further improving the stability of positioning. Even when the silicone foam is subjected to external forces such as cutting force, it can effectively prevent it from sliding at the positioning plate 400, ensuring cutting accuracy. The anti-slip layer can be a rubber layer or a silicone layer.

[0054] The working principle and usage process of this utility model are as follows: The whole is supported by the cutting table 100. Two control seats 300 are symmetrically installed on the cutting table 100. The positioning plate 400 on it is used to position and clamp the silicone foam from both sides. The ventilation plate 102 installed in the mounting groove 101 at the top of the cutting table 100 is flush with the cutting table 100. The fan 200 at the bottom of the cutting table 100 works through the air inlet end connected to the mounting groove 101. When the fan 200 is started, it will form a negative pressure in the mounting groove 101, so that the silicone foam placed on the ventilation plate 102 is adsorbed on the ventilation plate 102, achieving a flat and close fit of the whole.

[0055] The support plate 103 in the mounting slot 101 supports the ventilation plate 102, preventing it from deforming under stress. The mesh structure of the ventilation plate 102 and the support plate 103 provides a flow channel for airflow, ensuring that negative pressure can be applied evenly to the silicone foam. The two movable slots 104 on the top of the cutting table 100 provide a moving track for the control seat 300. The power source 301 drives the control seat 300 to move within the movable slots 104 via a power shaft, thereby adjusting the distance between the two control seats 300 and the positioning plate 400 to accommodate silicone foam of different widths.

[0056] The through hole 302 on one side of the control base 300 is used to install the positioning plate 400. The limiting head 303 in the connecting groove can limit and fix the positioning plate 400 under the drive of the lead screw 304. By rotating the knob 305 connected to the lead screw 304, the pressure of the limiting head 303 on the positioning plate 400 can be adjusted, thereby adjusting the position of the positioning plate 400 and ensuring the stability of the positioning. The rotating plate 401 in the groove 402 at the bottom of the positioning plate 400 can rotate flexibly, and the flattening roller 403 at one end is in the elastic element Under the elastic force of 404, it always keeps in contact with the surface of the silicone foam. During the movement of the silicone foam, the flattening roller 403 rolls to smooth the wrinkles on the edge of the material. The elasticity of the elastic element 404 can also adapt to silicone foam of different thicknesses, avoiding excessive pressure that could damage the material. The ventilation holes on the bottom wall of the mounting groove 101 ensure that the fan 200 can effectively draw air out of the mounting groove 101, enhancing the negative pressure effect. The anti-slip layer on the bottom of the positioning plate 400 increases the friction between it and the silicone foam, further preventing the material from sliding.

[0057] In this solution, the mechanical positioning of the dual-sided control seat 300 and the positioning plate 400 can effectively limit the overall displacement of the silicone foam and prevent the material from shifting laterally. At the same time, the negative pressure environment formed by the fan 200 through the mounting groove 101 and the ventilation plate 102 can adsorb the silicone foam onto the surface of the cutting table 100. This solves the problem that existing tooling can only position the edges, the middle of the material, and the non-edge areas that are suspended due to bending. It allows the silicone foam to completely adhere to the surface of the cutting table 100, fundamentally reducing the cutting size deviation caused by the loose material adhesion.

[0058] The support plate 103 works in conjunction with the mesh structure ventilation plate 102 to provide stable support for the ventilation plate 102, preventing it from deforming under the pressure of the silicone foam or the negative pressure adsorption force, thus ensuring the flatness of the cutting table 100. It also forms a smooth airflow channel through the hollow area of ​​the mesh structure, allowing the negative pressure to be applied evenly to the silicone foam, ensuring consistent force on all parts of the material, further improving the tightness of the material bonding and reducing cutting errors.

[0059] The moving groove 104 of the cutting table 100 cooperates with the power source 301 to flexibly adjust the position of the control seat 300 and the positioning plate 400 according to the width specifications of the silicone foam, so that the tooling can be adapted to materials of different widths and improve the versatility of the tooling; the through hole 302, connecting groove, limit head 303, lead screw 304 and knob 305 of the control seat 300 can accurately adjust the height of the positioning plate 400 to adapt to silicone foam of different thicknesses, ensure that the positioning plate 400 reliably clamps the edge of the material, and avoid cutting size deviation caused by inaccurate positioning.

[0060] The groove 402, rotating plate 401, flattening roller 403, and elastic element 404 of the positioning plate 400 can smooth out wrinkles and warps on the material edges during the conveying or positioning of silicone foam. The elastic element 404 can adaptively adjust the pressure of the flattening roller 403 on the material, ensuring a smoothing effect without damaging the material and reducing cutting size deviations caused by material wrinkles. The anti-slip layer at the bottom of the positioning plate 400 enhances the friction between the positioning plate 400 and the material edge, further preventing the material from sliding during the cutting process and improving cutting accuracy.

[0061] The ventilation holes on the bottom wall of the mounting slot 101, in conjunction with the fan 200, provide a stable negative pressure environment inside the mounting slot 101, enhancing the adsorption effect on the silicone foam and ensuring that the material always adheres to the surface of the cutting table 100, thus guaranteeing the accuracy of the cutting dimensions as a whole.
