[0031] Please see Figures 1-7 In this embodiment of the present invention, a silicone sheet cutting device includes an upper mold base 1, support columns 2, and a lower mold base 3. A limiting through hole 11 is formed on the bottom surface of the upper mold base 1, and a punching block 12 for punching silicone sheets is provided at the limiting through hole 11. The punching block 12 is slidably installed within the limiting through hole 11. A cylinder 13 is provided on the upper end face of the upper mold base 1, and the output end of the cylinder 13 is connected to the punching block 12 to drive the punching block 12 to rise and fall. The lower mold base 3 has at least two first mounting holes 31, which are evenly distributed on the upper end face of the lower mold base 3 near the left and right edges. Two support columns 2 are correspondingly provided on the lower mold base 3, with one end of each support column 2 inserted into the first mounting hole 31. Inside the hole 31, the other end of each support column 2 is detachably installed on the bottom surface of the upper mold base 1 to support the upper mold base 1. The upper end surface of the lower mold base 3 is provided with a punching through hole 33, which is directly opposite the punching block 12. The lower mold base 3 is provided with a guide plate 34 to guide the silicone strip 5 to be punched. The guide plate 34 is installed on the upper end surface of the lower mold base 3. The guide plate 34 is provided with a guide hole 341, which is connected to the first punching hole. The front and rear sides of the guide plate 34 are provided with an upwardly protruding first flange 342. When the silicone strip 5 to be punched is placed on the upper end surface of the guide plate 34, the first flange 342 respectively locks the front and rear sides of the silicone strip 5 to be punched.

[0032] The cutting device also includes a conveying module for feeding materials. The conveying module is located on the left or right side of the lower die base 3. The conveying module includes a conveyor belt 41, a drive shaft 42, a driven shaft 43, a support frame 44, a drive belt 45, and a rotary motor 46. The conveyor belt 41 is a closed strip structure. The drive shaft 42 is rotatably mounted on the front end of the support frame 44, and the driven shaft 43 is rotatably mounted on the rear end of the support frame 44. The conveyor belt 41 is fitted over the upper end of the support frame 44 and covers the drive shaft 42 and the driven shaft 43 respectively. The drive belt 45 is also a closed strip structure. One end of the drive belt 45 is fitted over the drive end of the rotary motor 46, and the other end of the drive belt 45 is fitted over one end of the drive shaft 42 to drive the drive shaft 42 to rotate. When the rotary motor 46 drives the drive shaft 42 to rotate, the drive shaft 42 can drive the conveyor belt 41 to achieve conveying, which can transfer the silicone strip 5 to be punched to the guide plate 34.

[0033] Further as Figure 7 As shown in this embodiment of the invention, the support frame 44 has upwardly protruding second flanges 441 on both its front and rear sides for guiding and limiting the delivery of silicone. Specifically, the second flanges 441 are integrally connected to the support frame 44 and can be machined.

[0034] Further as Figure 7As shown, in this embodiment of the invention, the support frame 44 is provided with at least four support legs 442. The upper ends of the support legs 442 are integrally connected to the upper surface of the support frame 44, and the four support legs 442 are evenly distributed on the upper surface of the support frame 44. The lower end of the support frame 44 is provided with a support portion 4421, the cross-section of which is not smaller than the cross-section of the support legs 442. Specifically, the support portion 4421 has a large contact area with the ground, which allows the support legs 442 to provide more stable support for the support frame 44, ensuring stability during transmission.

[0035] Further as Figures 4-6 and Figure 8 As shown in this embodiment of the invention, the support column 2 is provided with an adjustment structure for adjusting the distance between the upper die base 1 and the lower die base 3 to accommodate silicone strips 5 of different thicknesses to be punched. The following scheme can be referenced: the bottom surface of the upper die base 1 has at least two second mounting holes 14, which are through holes. The positions of the second mounting holes 14 correspond to the positions of the first mounting holes 31, i.e., they are located on the same axis. The support column 2 is provided with a retaining ring 21 for adjusting the distance between the upper die base 1 and the lower die base 3. The retaining ring 21 has a threaded inner hole 211. The upper surface of the support column 2 is provided with external threads and extends downward to the middle or three-quarters of the support column 2. The upper thread of the support column 2 is connected to the threaded inner hole 211, allowing the retaining ring 21 to slide on the support column 2. When the upper end of the support column 2 is inserted into the second mounting hole 14, the upper end face of the retaining ring 21 abuts against the bottom surface of the upper mold base 1. By adjusting the position of the retaining ring 21 on the support column 2, the distance between the upper mold base 1 and the lower mold base 3 can be adjusted. For example, the further the retaining ring 21 slides downward, the smaller the distance between the upper mold base 1 and the lower mold base 3, and vice versa. On the other hand, the support column 2 and the upper mold base 1 adopt a detachable connection method, which is conducive to timely replacement in case of component damage and has a certain degree of flexibility.

[0036] Further as Figure 1 and Figure 4 As shown in the embodiment of this utility model, the bottom of the lower mold base 3 is provided with a storage structure for storing the cut silicone sheets. The following scheme can be referred to: The bottom of the lower mold base 3 is provided with a support base 35. The upper end face of the base 35 abuts against the bottom surface of the lower mold base 3. The end face of the base 35 near the punching through hole 33 is provided with a feeding hole 36. The feeding hole 36 is connected to the punching through hole 33. The base 35 is provided with a storage cabinet 37. The storage cabinet 37 is slidably installed on the front or rear side of the base 35. The feeding hole 36 is connected to the storage cabinet to form a material dropping channel for the silicone sheets. The silicone sheets punched by the punching block 12 fall from the material dropping channel into the storage cabinet 37.

[0037] Further as Figure 4As shown in this embodiment of the utility model, the connection between the storage cabinet 37 and the base 35 can be achieved using the following scheme: a slot 351 is provided on the front or rear side of the base 35, the storage cabinet 37 is slidably installed in the slot 351, the storage cabinet 37 is provided with a handle 371 for easy gripping and pulling the storage cabinet 37 out of the slot 351, and the handle 371 is detachably installed on the front side of the storage cabinet 37. Specifically, the connection between the handle 371 and the storage cabinet 37 includes, but is not limited to, threaded connection, snap-fit ​​connection, and riveting.

[0038] Further as Figure 1 and Figure 3 As shown in this embodiment of the invention, the base 35 is provided with at least four casters 352, which are evenly distributed on the bottom surface of the base 35. Specifically, the casters 352 can be connected to the base 35 by means of threaded connection or snap-fit ​​connection. By providing casters 352 to the base 35, it is easy for people to move the base, giving the base 35 a certain degree of flexibility.

[0039] The working principle of this utility model is as follows: The silicone strip 5 to be punched is placed on the conveyor belt 41. The rotating motor 46 drives the drive shaft 42 to rotate, thereby driving the conveyor belt 41 to achieve the conveying effect. The conveyor belt 41 transports the silicone strip 5 to be punched to the guide plate 34. When the silicone strip 5 to be punched covers the punching through hole 33, the driving cylinder 13 drives the punching block 12 to press down to punch out the silicone sheet. The silicone sheet falls into the punching through hole 33, and then falls from the punching through hole 33 to the feed hole 36, and then from the feed hole 36 into the storage cabinet 37. No manual cutting is required, and the feeding is optimized. Through the cooperation of the conveyor belt 41 and the punching block 12, punching can be carried out continuously, which can improve the production efficiency of silicone sheets.

[0040] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
