[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] like Figures 1 to 7As shown, a silicone rubber sheet punching device includes: a machine base 1, a base assembly 2 on the machine base 1, a detachable lower template 3 on the base assembly 2, a pressing assembly 4 on the machine base 1, an upper template 5 on the pressing assembly 4 that can cooperate with the lower template 3 to press the sheet, a first cleaning device 6 on the machine base 1 for cleaning the lower template 3, a second cleaning device 7 on the machine base 1 for cleaning the sheet to be processed, and a positioning assembly 8 on the base assembly 2 for pushing the lower template 3, causing the lower template 3 to move relative to the base assembly 2 to a predetermined position and keeping the lower template 3 in that position.

[0026] In use, the vulcanized sheet is placed on the lower template 3, and then the lower template 3 is placed on the base assembly 2. The positioning assembly 8 is operated to move the lower template 3 to a predetermined position. At the same time, due to the setting of the positioning assembly 8, the lower template 3 is kept in the predetermined position. Finally, the pressing assembly 4 is activated, and the upper template 5 on the pressing assembly 4 covers the lower template 3, cutting the sheet according to the predetermined shape and size. Since the lower template 3 is detachably connected to the base assembly 2, it is convenient to place the sheet quickly, improving efficiency. At the same time, the positioning assembly 8 can accurately push the lower template 3 to the predetermined position and keep it stable, further ensuring the continuity and efficiency of the punching process. The first cleaning device 6 can clean the impurities on the surface of the lower template 3 in time, and the second cleaning device 7 cleans the sheet to be processed. The two work together to quickly clean and proceed with the next punching, improving efficiency. There is no need for manual wiping, making the subsequent punching efficiency even higher.

[0027] The base assembly 2 includes a base plate 21 connected to the machine base 1. Multiple first slide rails 22 are connected to the base plate 21. Each first slide rail 22 is connected to a first slider 23 capable of sliding back and forth relative to it. A mounting plate 24 capable of sliding along with the first sliders 23 is disposed between the multiple first sliders 23. Two support plates 25 are spaced apart on the mounting plate 24. Multiple second slide rails 26 are disposed on each support plate 25. Second sliders 27 that move up and down relative to each second slide rail 26 are disposed on it. A connecting plate 28 is disposed between the multiple second sliders 27. The connecting plate 28 is provided with an outwardly extending first connecting bracket 29. The positioning assembly 8 is disposed on the first connecting bracket 29. A first driving member 2a is provided between the mounting plate 24 and the base plate 21, enabling the mounting plate 24 to slide relative to the base plate 21. A fourth driving member 2b is provided between the connecting plate 28 and the mounting plate 24. When the lower template 3 needs to be placed, the first drive component 2a is activated. The first drive component 2a causes the mounting plate 24 to slide relative to the base plate 21 and slide to the outside of the top pressing component 4. At this position, it is convenient to place the lower template 3. At the same time, the fourth drive component 2b is activated, and the second slider 27 moves upward relative to the second slide rail 26. At this time, the connecting plate 28 and the first connecting bracket 29 slide upward to the top, and then the lower template 3 is placed on the first connecting bracket 29. The fourth drive component 2b is activated, causing the connecting plate 28 and the first connecting bracket 29 to return to the bottom relative to the two support plates 25. The first drive component 2a is activated, and the mounting plate 24 slides relative to the base plate 21 to its original position and is located below the top pressing component 4. This setting makes it convenient to place the sheet and pick up the punched sample. It is very convenient to use, requires no manual operation from the user, can achieve semi-automation, facilitates material loading and unloading, and is more convenient to use.

[0028] The lower template 3 is provided with protruding forming protrusions 31. A positioning component is also provided between the connecting plate 28 and the lower template 3 to position them. The positioning component includes a protruding post 32 located at one end of the lower template 3, and a positioning hole 281 is provided on the connecting plate 28 for the protruding post 32 to be inserted. The protruding post 32 and the positioning hole 281 cooperate to achieve precise and rapid positioning of the lower template 3 and the connecting plate 28, ensuring that the position and height of the lower template 3 are consistent each time it is installed, thereby improving punching accuracy and product quality.

[0029] The positioning component 8 includes a positioning seat 81 connected to a first connecting bracket 29. A sliding column 82 is mounted on the positioning seat 81 and can slide relative to it. A handle 83 is also mounted on the positioning seat 81 and is rotatably connected to the positioning seat 81. A linkage 84 is also provided between the handle 83 and the sliding column 82. One end of the linkage 84 is rotatably connected to the handle 83, and the other end is rotatably connected to the sliding column 82. A push block 85 is also provided at the end of the sliding column 82 to push the lower template 3. This positioning component 8, through the ingenious cooperation of the handle 83, linkage 84, and sliding column 82, achieves rapid and precise pushing and positioning of the lower template 3. The operator only needs to rotate the handle 83 to move the sliding column 82 via the linkage 84, causing the push block 85 to push the lower template 3 to the predetermined position and maintain a pressing state. The operation is simple and quick, greatly improving positioning efficiency and accuracy.

[0030] The mounting plate 24 is also provided with a support block 241 that can support the lower template 3. With the support block 241 on the mounting plate 24, the connecting plate 28 and the first connecting bracket 29 are reset downwards to the bottom relative to the two support plates 25. At this time, the support block 241 can provide an upward support force for the lower template 3, ensuring that it remains flat and stable during the punching process.

[0031] The first connecting bracket 29 is provided with a sliding groove 291, and the lower template 3 is provided with a top abutting part 33 that can be inserted into the sliding groove 291 and abut against the groove wall of the sliding groove 291. During the punching process, the tight abutting of the top abutting part 33 against the groove wall of the sliding groove 291 can effectively prevent the lower template 3 from shifting or shaking, thereby ensuring punching accuracy and product quality. At the same time, the top abutting part 33 cooperates with the sliding groove 291 to guide the lower template 3 to slide relative to the first connecting bracket 29.

[0032] The base plate 21 is also provided with a top plate 211 that can abut against the mounting plate 24 to prevent the mounting plate 24 from moving further. The top plate 211 on the base plate 21 can abut against the mounting plate 24, thereby effectively preventing the mounting plate 24 from moving further, playing a limiting role, facilitating the positioning of the mounting plate 24, and facilitating the removal and placement of the lower template 3.

[0033] The top-pressing assembly 4 includes a mounting bracket 41 spanning the base assembly 2. A second driving member 42 is mounted on the mounting bracket 41, and the upper template 5 is connected to the output shaft of the second driving member 42. The upper template 5 has a forming groove 51 and a guide rod 52 extending to and sliding relative to the mounting bracket 41. The forming groove 51 on the upper template 5 precisely matches the forming protrusion 31 of the lower template 3, ensuring that the punched product has a regular shape and accurate dimensions. The guide rod 52 extends to the mounting bracket 41 and can slide relative to it, further enhancing the movement stability and guiding accuracy of the upper template 5 during the punching process, effectively avoiding punching failures or product quality problems caused by the upper template 5 shaking or shifting.

[0034] The first cleaning device 6 includes a first bracket 61 disposed on one side of the base assembly 2. A third slide rail 62 is disposed on the first bracket 61, a third slider 63 is disposed on the third slide rail 62, and a first connecting frame 64 is disposed on the third slider 63. A second driving member 65 is disposed between the first connecting frame 64 and the first bracket 61, allowing the first connecting frame 64 to slide relative to the first bracket 61. A vertically arranged roller brush assembly 66 is also disposed on the first bracket 61, and a shelf 67 for placing the lower template 3 is disposed on the first connecting frame 64. After punching is completed, the lower template 3 is placed on the shelf 67, and then the third driving member 65 is activated. Activation of the second driving member 65 drives the first connecting frame 64, which, through the cooperation of the third slide rail 62 and the third slider 63, moves relative to the first bracket 61, causing the lower template 3 to pass through the roller brush assembly 66 for cleaning. The roller brush assembly 66 also has a suction port to suck up the impurities cleaned by the roller brush assembly 66.

[0035] The second cleaning device 7 includes a second bracket 71 disposed on one side of the base assembly 2. A fourth slide rail 72 is mounted on the second bracket 71, a fourth slider 73 is mounted on the fourth slide rail 72, and a second connecting frame 74 is mounted on the fourth slider 73. A fourth driving member 75 is disposed between the second connecting frame 74 and the second bracket 71, allowing the second connecting frame 74 to slide relative to the second bracket 71. A vertically arranged suction assembly 9 is also disposed on the second bracket 71, and multiple suction heads 741 capable of clamping and positioning are disposed on the second connecting frame 74. Before punching, the sheet is placed on the multiple suction heads 741, and then the fourth driving member 75 is activated. Activation of the fourth driving member 75 drives the second connecting frame 74, which slides relative to the second bracket 71 through the cooperation of the fourth slide rail 72 and the fourth slider 73, causing the sheet to pass through the suction assembly 9. The suction assembly 9 effectively adsorbs and cleans dust and impurities from the surface of the compressed sheet.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
