[0023] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0024] Figure 1-3 As one embodiment of the utility model, a silicone keypad trimming machine comprises a workbench 1, a cutting mechanism 2 for cutting silicone keypads is arranged above the workbench 1, the cutting mechanism 2 comprises a base 21 fixedly connected to the workbench 1 for placing silicone sheets to be trimmed, a lower pressing seat 22 for pressing down the trimming is arranged above the base 21, a hydraulic press 23 for driving the lower pressing seat 22 is arranged above the lower pressing seat 22, a placing portion 3 for placing multiple layers of silicone sheets to be cut is arranged above the workbench 1 on one side of the cutting mechanism 2, a pushing portion 4 for pushing the silicone sheets to be cut on the placing portion 3 is arranged above the workbench 1 on the side opposite to the cutting mechanism 2, in actual work, an adapted cutting knife assembly is installed on the bottom surface of the lower pressing seat 22 according to actual needs, the silicone sheets to be trimmed are stacked in the placing portion 3, the silicone sheets are pushed one by one into the top of the base 21 by the pushing of the pushing portion 4, and then the lower pressing seat 22 is pressed down by the hydraulic press 23 to trim the silicone sheets above the base 21;

[0025] The placement part 3 includes a support seat 31 fixedly connected to the workbench 1, a support sheet 32 ​​for placing the silicone sheet to be trimmed is provided above the support seat 31, an elastic pressing plate 33 for pressing the silicone sheet downward is provided above the support sheet 32, the elastic pressing plate 33 includes a vertical rod 331 arranged at the four corners of the support sheet 32 ​​and extending upward, a spring 332 is provided on the outer side of the vertical rod 331, and a pressing plate 333 movably connected to the vertical rod 331 is fixedly connected to the bottom end of the spring 332, and the vertical rod 331 is provided with a vertical rod 332. The top of 331 is fixedly connected with a top plate 334. In actual work, the silicone sheets to be trimmed are placed layer by layer between the supporting sheet 32 ​​and the pressing plate 333. As the silicone sheets are stacked layer by layer, the pressing plate 333 is pushed upward along the vertical rod 331, so that the top surface of the pressing plate 333 presses the spring 332 upward. Due to the rebound force of the spring 332, the pressing plate 333 is pressed down and fits the silicone sheets, so that the multiple layers of silicone sheets are limited between the supporting sheet 32 ​​and the pressing plate 333.

[0026] The pushing part 4 includes a horizontally arranged hydraulic push rod assembly 41, and the output end of the hydraulic push rod assembly 41 is provided with an insert push block 42 for separating and pushing the silicone sheet above the supporting sheet 32; the height of the support seat 31 is adapted to the height of the base 21, and the supporting sheet 32 ​​extends toward one end of the cutting mechanism 2 to the top of the base 21 and contacts the top wall of the base 21. In actual work, by starting the hydraulic push rod assembly 41, the insert push block 42 pushes the silicone sheet located at the bottom of the silicone sheet and in contact with the supporting sheet 32 ​​along the supporting sheet 32 ​​to the base 21 in contact with the supporting sheet 32, thereby facilitating the lower pressing seat 22 to trim the silicone sheet above the base 21.

[0027] The hydraulic push rod assembly 41 includes a fixed seat 411 fixed to the workbench 1, and a horizontal hydraulic rod 412 is arranged above the fixed seat 411 and is perpendicular to the placement portion 3. The length of the horizontal hydraulic rod 412 is greater than the distance between the placement portion 3 and the cutting mechanism 2. The output end of the horizontal hydraulic rod 412 faces the placement portion 3, and the insert push block 42 is movably connected to the end of the horizontal hydraulic rod 412 facing the placement portion 3. In actual work, when it is necessary to push the silicone sheet above the pressure plate 333, the horizontal hydraulic rod 412 is started to push the insert push block 42 to the maximum contact with the push pressure plate 333. The bottom silicone sheet contacts and pushes the silicone sheet toward the base 21; the insert push block 42 includes an insert plate 421 fixedly arranged at the end of the horizontal hydraulic rod 412, and a horizontal insert plate 422 extending toward the placement portion 3 for layering the multi-layer silicone sheets is inserted in the insert plate 421. The bottom surface of the horizontal insert plate 422 is provided with a push block 423 in contact with the silicone sheet on the side facing the horizontal hydraulic rod 412. In actual work, when the horizontal hydraulic rod 412 is started and the insert push block 42 is pushed, the insert plate 421 is first inserted into the silicone sheet in contact with the pressure plate 333 and the silicone sheet adjacent to the upper side of this group of silicone sheets. The gap between the films is used to separate the stacked silicone sheets. Then, the push block 423 located on the bottom surface of the horizontal insert 422 facing the side of the horizontal hydraulic rod 412 contacts the side wall of the silicone sheet that is located at the bottom and contacts the supporting sheet 32. As the horizontal hydraulic rod 412 continues to move, the silicone sheet at the bottom is pushed to the top of the base 21. Then, when the horizontal hydraulic rod 412 returns to its original position, the insert push block 42 is brought back to the side of the placement part 3 facing the push part 4. Due to the downward rebound force of the spring 332, the remaining silicone laminated sheets in the placement part 3 are The pressed plate 333 is continuously pressed downward to make the silicone sheet at the bottom contact with the supporting sheet 32, so as to facilitate the contact and push of the insert push block 42 next time. Since the thickness of the silicone key sheets produced for different products is different, in order to facilitate the adjustment of the thickness of the horizontal insert 422 relative to the supporting sheet 32, the insert plate 421 and the horizontal insert 422 are set to be detachable and replaceable. When silicone sheets of different thicknesses need to be pushed, the horizontal insert 422 is removed and replaced with a horizontal insert 422 of a thickness matching the edge to be cut, so as to realize the pushing of silicone sheets of different types.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
