Description

Technical Field

[0001] This utility model relates to the field of edge trimming device technology, specifically a silicone pad edge trimming device. Background Technology

[0002] Silicone pads are a type of silicone product with high market demand. After processing, their edges often have burrs and imperfections, requiring trimming. Existing silicone pad trimming devices, such as the one disclosed in CN 219617855U, while improving trimming efficiency to some extent, have significant shortcomings in terms of clamping and supporting the silicone pads. This device can only clamp and position silicone pads with holes in the center; it cannot effectively fix silicone pads without holes or with special hole structures, limiting the device's applicability. Moreover, during trimming, the silicone pad at the cutter position lacks support, causing it to easily move up and down during rotation, severely affecting cutting accuracy and resulting in inconsistent product quality, failing to meet the market demand for high-quality silicone pads. Utility Model Content

[0003] This utility model mainly provides a silicone pad trimming device, which solves the problems of existing technology that can only clamp and position silicone pads with holes in the middle, and the lack of support for silicone pads located at the cutting blade position, which makes the silicone pads easy to move up and down during the rotating trimming process, seriously affecting the cutting accuracy.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A silicone pad trimming device includes a mounting platform with a mating platform. A rotating mechanism for supporting and rotating the silicone pad is mounted on the mating platform. A blade holder is mounted on the mounting platform corresponding to one side of the mating platform, and a horizontal displacement mechanism with a cutting blade is mounted on the blade holder. A clamping mechanism is mounted on the blade holder above the rotating mechanism, cooperating with the rotating mechanism to clamp the silicone pad. A telescopic support mechanism is mounted on the mating platform corresponding to the cutting blade direction, supporting the silicone pad within a certain range. The telescopic direction of the telescopic support mechanism is consistent with the movement direction of the horizontal displacement mechanism. Here, "certain range" refers to the support area of ​​the telescopic support mechanism.

[0006] Furthermore, the rotating mechanism includes a rotating shaft rotatably connected to the mating platform, a support platform provided at the upper end of the rotating shaft, and a first electric motor provided on the mounting platform for driving the rotating shaft to rotate.

[0007] Furthermore, the cutting blade includes a blade holder vertically disposed on the horizontal displacement mechanism, and a blade body detachably connected to the blade holder.

[0008] Furthermore, the clamping mechanism includes a lifting cylinder positioned above the rotating mechanism. A connecting seat is provided at the lower end of the lifting cylinder, and a pressing table is rotatably connected to the connecting seat. The pressing table moves up and down by being driven by the lifting cylinder.

[0009] Furthermore, the horizontal displacement mechanism includes a horizontal screw rotatably connected to the tool holder, a horizontal guide rod disposed on the tool holder and parallel to the axial direction of the horizontal screw, a movable block threadedly connected to the horizontal screw, and a second motor for driving the horizontal screw to rotate, wherein the movable block is slidably connected to the horizontal guide rod.

[0010] Furthermore, the telescopic support mechanism includes a support frame disposed on one side of the mating platform. The support frame has a displacement groove, and a horizontal platform is slidably connected in the displacement groove. A support plate is disposed on the horizontal platform, and multiple ball bearing assemblies are distributed on the support plate. A connecting frame is disposed on the tool holder, and the connecting frame is detachably connected to the outer end of the horizontal platform. The horizontal platform slides in the displacement groove driven by the horizontal displacement mechanism.

[0011] Beneficial effects: 1. The clamping mechanism, in conjunction with the rotating mechanism, can clamp the silicone pad from both above and below. The clamping mechanism can also rotate with the rotating mechanism, thus clamping silicone pads without a central hole and silicone pads of different thicknesses. 2. The telescopic support mechanism can support the silicone pad. Since the telescopic support mechanism is located between the mating table and the cutting blade, it can provide support to the silicone pad at the cutting position of the cutting blade within a certain range. This support prevents the silicone pad from moving up and down due to lack of support, improving the cutting accuracy of the cutting blade and ensuring production quality. 3. The telescopic support mechanism can extend and retract in the direction of the horizontal displacement mechanism, thus adjusting the support position of the telescopic support mechanism. Combined with the cutting blade after position adjustment by the horizontal displacement mechanism, it can achieve edge trimming of silicone pads of different sizes. Attached Figure Description

[0017] The technical solution of the silicone pad trimming device of this utility model will be further described in detail below with reference to the embodiments.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, this embodiment of a silicone pad trimming device includes a mounting platform 1, a mating platform 2 on the mounting platform 1, and a rotating mechanism on the mating platform 2 for supporting and rotating the silicone pad. A blade holder 3 is mounted on one side of the mounting platform 1 corresponding to the mating platform 2, and a horizontal displacement mechanism with a cutting blade mounted on the blade holder 3. A clamping mechanism is mounted on the blade holder 3 above the rotating mechanism. A telescopic support mechanism is mounted on the mating platform 2 corresponding to the cutting blade direction. The telescopic support mechanism supports silicone pads within a certain range, and its telescopic direction is consistent with the moving direction of the horizontal displacement mechanism. Specifically, the mounting platform 1 can have a single mating platform 2 or multiple mating platforms 2, thereby enabling the trimming of multiple silicone pads. When the number of mating platforms 2 increases, other components are added accordingly. Specifically, the clamping mechanism is used to cooperate with the rotating mechanism to clamp the silicone pad, meaning that when the clamping mechanism moves up and down to clamp the silicone pad, it can also rotate in conjunction with the rotating mechanism. In use, place the silicone pad to be trimmed on the rotating mechanism on the mating table 2, and lower it through the clamping mechanism. The rotating mechanism clamps the silicone pad from the top and bottom. At the same time, the telescopic support mechanism supports the silicone pad within a certain range between the cutter and the rotating mechanism. The support position of the telescopic support mechanism between the cutter and the mating table 2 can be adjusted, and the horizontal displacement mechanism drives the cutter to move horizontally, so as to trim silicone pads of different sizes. After cutting, release the clamping mechanism and the rotating mechanism from the silicone pad to remove the silicone pad. Using the structure of this application, a silicone pad can be clamped from above and below by a clamping and holding mechanism in conjunction with a rotating mechanism. The clamping and holding mechanism can rotate in conjunction with the rotating mechanism to clamp silicone pads without a central hole, and to clamp silicone pads of different thicknesses. Simultaneously, a telescopic support mechanism can support the silicone pad. Since the telescopic support mechanism is located between the mating table 2 and the cutting blade, it can provide support for the silicone pad at the cutting position of the cutting blade within a certain range. This support prevents the silicone pad from moving up and down due to lack of support, improving the cutting accuracy of the cutting blade and ensuring production quality. Furthermore, the telescopic support mechanism can extend and retract in the direction of the horizontal displacement mechanism, thereby adjusting the support position of the telescopic support mechanism. Combined with the cutting blade whose position has been adjusted by the horizontal displacement mechanism, it enables the cutting of silicone pads of different sizes.

[0020] In one embodiment, the rotating mechanism includes a rotating shaft rotatably connected to the mating platform 2, a support platform 4 at the upper end of the rotating shaft, and a first motor 5 for driving the rotating shaft to rotate on the mounting platform 1. Specifically, the first motor 5 can be located at any position on the mounting platform 1, and can drive the rotating shaft to rotate directly or through a transmission component. It can drive a single rotating shaft to rotate, or drive multiple rotating shafts to rotate through a rotating component. With this structure, the silicone pad can be supported by the support platform 4, and the silicone pad can be clamped by the support platform 4 in conjunction with the clamping mechanism.

[0021] In one embodiment, the cutting blade includes a blade holder 6 vertically disposed on the horizontal displacement mechanism, and a blade body 7 detachably connected to the blade holder 6. Specifically, the blade body 7 can be detachably connected to the blade holder 6 in any existing manner. This structure facilitates the replacement of the blade body 7 and allows for the subsequent installation of corresponding components on the blade holder 6.

[0022] In one embodiment, the clamping mechanism includes a lifting cylinder 8 positioned above the rotating mechanism. A connecting seat 9 is located at the lower end of the lifting cylinder 8, and a pressing platform 10 is rotatably connected to the connecting seat 9. The pressing platform 10 moves up and down under the influence of the lifting cylinder 8. The pressing platform 10 may have a mating shaft, and the connecting seat 9 has a mating groove. A bearing is positioned between the mating shaft and the mating groove. This structure allows the lifting cylinder 8 to move the connecting seat 9 and the pressing platform 10 up and down, thereby clamping the silicone pad between the pressing platform 10 and the support platform 4. The rotatable connection between the pressing platform 10 and the connecting seat 9 does not affect the rotation of the pressing platform 10 and the support platform 4.

[0023] In one embodiment, the horizontal displacement mechanism includes a horizontal screw 11 rotatably connected to the tool holder 3, a horizontal guide rod 12 disposed on the tool holder 3 and parallel to the axial direction of the horizontal screw 11, a moving block 13 threadedly connected to the horizontal screw 11, and a second motor 14 for driving the horizontal screw 11 to rotate. The moving block 13 is slidably connected to the horizontal guide rod 12. Specifically, the tool holder 6 is disposed on the moving block 13. With this structure, the second motor 14 can drive the horizontal screw 11 to rotate, thereby coordinating with the displacement of the horizontal guide rod 12 and the linear moving block 13, thus achieving the displacement of the tool holder 6 and the tool body 7.

[0024] In one embodiment, the telescopic support mechanism includes a support frame 15 disposed on one side of the mating platform 2. The support frame 15 has a displacement groove, and a horizontal platform 16 is slidably connected within the displacement groove. A support plate 17 is disposed on the horizontal platform 16, and multiple ball bearing assemblies 18 are distributed on the support plate 17. A connecting frame 19 is disposed on the tool holder 6, and the connecting frame 19 is detachably connected to the outer end of the horizontal platform 16. The horizontal platform 16 slides within the displacement groove driven by the horizontal displacement mechanism. Specifically, arc-shaped guide rods are symmetrically arranged on the inner sidewall of the displacement groove, and an arc-shaped guide groove is formed on the horizontal platform 16 to mate with the arc-shaped guide rods, thereby allowing the arc-shaped guide groove and the arc-shaped guide rods to slide together. The ball bearing assemblies 18 can be existing bullseye ball bearings, as long as they can be installed on the support plate 17 without affecting the rotation of the ball body. Multiple ball bearing assemblies 18 are used to achieve multi-point support for the silicone pad. With this structure, the crossbeam 16 can slide within the displacement groove of the support frame 15, and one side of the crossbeam 16 is connected to the tool holder 6 via the connecting frame 19. Thus, when the tool holder 6 is displaced, it can drive the crossbeam 16 to slide, thereby driving the support plate 17 to move and realize the adjustment of the support position. After the support position is adjusted, it can provide good support for silicone pads of different sizes, thereby cooperating with the tool body 7 to perform good cutting and avoiding the problem of inaccurate processing accuracy caused by the silicone pad shifting up and down on the front side of the tool body 7 due to lack of support.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
