Description

Technical Field

[0001] This utility model relates to the field of die-cutting device technology, and in particular to a die-cutting device for silicone processing. Background Technology

[0002] Silicone, as a high-performance synthetic rubber, is highly favored for its excellent high and low temperature resistance, electrical insulation, chemical stability, physiological inertness, and good processing performance. It is widely used in many fields such as electronics, medical and health, automobile manufacturing, daily necessities, food processing, and sealing materials. Silicone materials are indispensable, especially in applications that require high and low temperature resistance, moisture resistance, mildew resistance, shock resistance, or biocompatibility.

[0003] Existing die-cutting equipment for silicone processing still has some shortcomings in practical use:

[0004] When the die-cutting device for processing silicone raw materials cuts silicone, a single person places the silicone raw material on the die-cutting table, cuts the silicone raw material, and then removes the cut-off product and replaces it with a new silicone raw material. The entire process of loading, cutting and unloading is inefficient. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing technology involves manually placing silicone raw materials on a die-cutting table, cutting the silicone raw materials, removing the cut-off finished products, and replacing them with new silicone raw materials, resulting in low efficiency throughout the entire material loading, cutting, and unloading process. Therefore, this invention proposes a die-cutting device for silicone processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A die-cutting device for silicone processing includes a frame with four lower cutting dies inside. A rotating shaft is rotatably connected inside the frame, with one end of the rotating shaft rotatably extending to the outside of the frame. A cross-shaped connecting frame is provided on one side of the inner wall of the frame and is fixedly sleeved on the outer wall of the rotating shaft. The cross-shaped connecting frame is located on one side of the four lower cutting dies.

[0008] In one possible design, a first sliding shaft is fixedly connected to one side of each of the four lower punching dies, and a cross-shaped connecting frame is rotatably sleeved on the outer wall of the four first sliding shafts. The four first sliding shafts extend to one side of the cross-shaped connecting frame. A second sliding groove is provided on one side inner wall of the frame, and the four first sliding shafts slide in the second sliding groove.

[0009] In one possible design, a second sliding shaft is fixedly connected to the other side of each of the four lower punching dies, and a first sliding groove is provided on the inner wall of the other side of the frame, with the four second sliding shafts sliding within the first sliding groove.

[0010] In one possible design, a grooved wheel is fixedly fitted at one end of the rotating shaft, a mating disc is fixedly connected to one side of the grooved wheel, a notched disc is rotatably connected inside the frame, an L-shaped push rod is fixedly connected to one side of the notched disc, and the notched disc mates with the mating disc, the L-shaped push rod mates with the grooved wheel, a drive motor is fixedly connected to one side of the frame, and one end of the output shaft of the drive motor is fixedly connected to the L-shaped push rod.

[0011] In one possible design, each of the four lower punching dies has four limiting blocks at its top.

[0012] In one possible design, a support frame is fixedly connected to the top of the frame, an upper punching die is provided below the support frame, a cylinder is fixedly connected to the top of the support frame, and one end of the cylinder's output shaft passes through the support frame and is fixedly connected to the top of the upper punching die.

[0013] In this application, the entire equipment consists of four lower cutting dies. The four lower cutting dies sequentially cycle through feeding, cutting, and unloading. Each lower cutting die has four limiting blocks on its top, which can be aligned according to their positions. When the drive motor is started, the output shaft of the drive motor drives the notched disc and the L-shaped push rod to rotate. The L-shaped push rod drives the grooved wheel to rotate 90 degrees, which in turn drives the rotating shaft to rotate and the cross link to rotate, thereby driving the lower cutting die to rotate 90 degrees. At the same time, the lower cutting die containing the silicone raw material rotates to the bottom of the upper cutting die. When the four lower cutting dies rotate, the second sliding shaft on one side of the lower cutting die rotates in the first sliding groove to horizontally limit the lower cutting die. The output shaft of the cylinder pushes the upper cutting die to cut the silicone material on the surface of the lower cutting die. After the silicone material is cut, it rotates 90 degrees again, and the lower cutting die located below the upper cutting die rotates to the discharge point, where the cut silicone product can be removed. The lower cutting die containing the silicone material rotates to the bottom of the upper cutting die for cutting.

[0014] Beneficial effects: In this utility model, the die-cutting device for silicone processing, through the cooperation and rotation of the cross frame, the first sliding shaft and the second sliding groove, and the cooperation of the second sliding shaft and the first sliding groove, can ensure that the lower punch die is always in a horizontal position when the cylinder rotates.

[0015] In this utility model, the die-cutting device for silicone processing, by setting up a mating disc, an L-shaped push rod, a notched disc and a grooved wheel, and a drive motor, achieves reliable indirect transmission and locking functions, ensuring stability and safety during the die-cutting process;

[0016] In this invention, the device significantly improves the production efficiency of silicone processing through an automated and precise die-cutting process. At the same time, due to the adoption of an efficient and reliable transmission and locking mechanism, energy consumption and failure rate are reduced, thereby reducing production costs.
