Technical Field

[0001] This utility model relates to the technical field of mica board production, and in particular to a mica board tearing machine. Background Technology

[0002] Mica board is an insulating material made by bonding mica paper with silicone rubber, heating, and pressing. It contains approximately 90% mica and 10% silicone rubber. Mica board possesses excellent insulation properties and high-temperature resistance, with a fire resistance temperature of 500℃ to 750℃, and maintains its performance even at high temperatures. Tear strength testing is required before it leaves the factory. Existing technology publication number CN209745670U discloses a plastic sheet tearing device, comprising a base plate, a positioning mechanism for positioning the plastic sheet, a clamping mechanism for clamping the plastic sheet, and a tearing mechanism for tearing the plastic sheet. The positioning mechanism includes a positioning seat and several positioning cylinders located on the positioning seat. The positioning seat is located on the base plate, and a linear groove is provided on one side of the positioning seat. The piston rod of each positioning cylinder is located within the linear groove. The clamping mechanism includes a gripper cylinder capable of moving along the length of the positioning seat, with the gripping end of the gripper cylinder corresponding to the position of the linear groove. The tearing mechanism includes a drive cylinder connected to the cylinder body end of the gripper cylinder via a connecting block. However, its structural strength is poor, its stability during use is poor, and it is inconvenient for tearing the plastic sheet. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a mica board tearing machine that increases structural strength, ensures stability during use, and improves tearing quality.

[0004] This utility model discloses a mica board tearing machine, including a worktable, multiple support legs, a clamping and fixing component, a pulling component, and a pressing component. Support legs are fixedly installed at the four corners of the bottom of the worktable to support the equipment. The clamping and fixing component is fixedly installed at the rear top of the worktable, and the pressing component is installed at the front top of the worktable via the pulling component. The board is clamped and fixed by the clamping and fixing component, and one end of the board is connected to the pressing component. The pressing component is moved by the pulling component to perform the tearing operation on the mica board, which increases the structural strength, ensures the stability during use, and improves the tearing quality.

[0005] Preferably, the clamping and fixing assembly includes a clamping frame, multiple hydraulic cylinders, a clamping plate, and a bearing plate. The clamping frame is fixedly installed at the rear of the top of the workbench. Multiple hydraulic cylinders are evenly installed on the top of the clamping frame, and the bottom of the hydraulic cylinders is connected to the clamping plate. The bearing plate is installed at the top of the workbench corresponding to the position of the clamping plate. The mica board is placed on the top of the bearing plate below the workbench, and the hydraulic cylinders are activated to push the clamping plate downward, which cooperates with the bearing plate to clamp and fix the board, preventing it from moving when tearing.

[0006] Preferably, the clamping frame also includes two guide sliders, multiple guide rods, two support arms, and support rollers. Guide grooves are provided on the inner walls of the left and right sides of the clamping frame. Guide sliders are installed on the side walls of the left and right ends of the clamping plate. The guide sliders are slidably installed in the guide grooves. Multiple guide rods are alternately slidably installed on the top of the clamping frame and the hydraulic cylinder. The bottom of the guide rods is connected to the top of the clamping plate. Support arms are installed on the left and right ends of the rear side wall of the worktable. Support rollers are rotatably installed between the two support arms. When the clamping plate moves downward, it drives the guide sliders to move in the guide grooves, and at the same time drives the guide rods to slide on the clamping frame, which limits and guides the clamping plate, increases the structural strength, and ensures the stability when tearing the plate. When the plate is fed, it is pushed on the support rollers, which support the bottom of the plate.

[0007] Preferably, the pulling assembly includes two lead screws, two reducers, two dual-output motors, two pulling blocks, and a pulling base plate. Pulling grooves are provided on the left and right sides of the front end of the top of the worktable. The lead screws are rotatably installed in the pulling grooves, and the input end of the lead screws is connected to the output end of the reducers. The dual-output motors are installed at the front end of the worktable towards the center, and the output ends of the dual-output motors are connected to the input ends of the reducers. The two pulling blocks are slidably installed in the pulling grooves, and the pulling blocks are screwed onto the outer wall of the lead screws. A pulling base plate is fixedly installed on the top of the pulling blocks. When the dual-output motors are started, the reducers drive the lead screws to rotate, which in turn moves the pulling blocks in the pulling grooves, causing the pulling base plate to move on the top of the worktable, thus realizing the tearing operation.

[0008] Preferably, the clamping assembly includes a pulling frame, multiple telescopic cylinders, multiple pressure plates, multiple sets of limiting guide rods, and multiple connecting plates. The pulling frame is installed on the top of the pulling base plate. Multiple telescopic cylinders are installed on the top of the pulling frame, and pressure plates are installed at the bottom of the telescopic cylinders. Limiting guide rods are slidably installed on the left and right sides of the telescopic cylinders on the top of the pulling frame. The bottom of the limiting guide rods is connected to the top of the pressure plates, and a connecting plate is installed on the top of the limiting guide rods. An avoidance hole is opened in the middle of the connecting plate. After one end of the sheet moves to the top of the pulling base plate, the telescopic cylinders are activated to push the pressure plates downward. When the pressure plates move, they drive the limiting guide rods to slide on the pulling frame, supporting and limiting the pressure plates to ensure the stability of the clamping. Multiple pressure plates can perform tearing operations on different parts of the sheet, which is convenient to use.

[0009] Preferably, it also includes a guide rod and a support block. A guide groove is provided in the middle of the top of the worktable, the guide rod is installed in the guide groove, and a support block is slidably installed on the outer wall of the guide rod. The top of the support block is connected to the bottom of the pull base plate. When the pull base plate moves, it drives the support block to slide on the guide rod, supporting the bottom of the pull base plate, enhancing the structural strength and ensuring stability.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the plate is clamped and fixed by the clamping and fixing component, and one end of the plate is connected to the pressing component. The pressing component is moved by the pulling component to perform the tearing operation on the mica plate, which increases the structural strength, ensures the stability during use, and improves the tearing quality.

Multiple pressure plates 19 can tear different parts of the board. The dual-output motor 12, through the reducer 11, drives the lead screw 10 to rotate, causing the pulling block 13 to move within the pulling groove, thus moving the pulling base plate 14 on top of the workbench 1 to achieve the tearing operation. As the pulling base plate 14 moves, it causes the support block 16 to slide on the guide rod 15, supporting the bottom of the pulling base plate 14.
