[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] Embodiment 1
[0020] according to Figure 1-Figure 3 As shown, a flame retardant thermal conductive silicone sheet cutting device comprises a mounting base 1, a cutting platform 2 is arranged inside the mounting base 1, a silicone sheet 3 is placed on the cutting platform 2, a quick cutting mechanism 4 is movably installed above the cutting platform 2, and a fixed length auxiliary mechanism 5 is arranged on the left and right sides of the cutting platform 2. During the cutting operation, the quick cutting mechanism 4 will move forward and backward under the action of the fixed length auxiliary mechanism 5, and after the position is determined, the quick cutting mechanism 4 will automatically cut the silicone sheet 3.
[0021] Specifically, the quick cutting mechanism 4 includes a horizontal slide rail 401 movably mounted above the mounting base 1, a side wall square groove 402 is provided on the inner side wall of the horizontal slide rail 401, a sliding protrusion 403 is movably mounted inside the horizontal slide rail 401, and movable pulleys 404 are rotatably mounted on the front and rear sides of the sliding protrusion 403, and the movable pulley 404 is located inside the side wall square groove 402. The movable pulley 404 can roll along the side wall square groove 402, and the sliding protrusion 403 moves horizontally along the horizontal slide rail 401. When the silicone is cut, the movable pulley 404 will rotate inside the square groove 402 of the side wall, and a sliding round rod 405 is movably installed inside the sliding protrusion 403. A cutting blade 406 is detachably installed on the lower end of the sliding round rod 405, and a return spring 407 is provided on the outer sleeve of the upper end of the sliding round rod 405. A clamping assembly 408 is provided at the corner of the cutting platform 2. When the silicone is cut, the clamping assembly 408 will first clamp and fix the sheet silicone 3, and then the cutting blade 406 will cut the sheet silicone 3.
[0022] Specifically, the fixed-length auxiliary mechanism 5 includes a mounting straight groove 501 symmetrically opened at the upper end of the mounting base 1, a guide round rod 503 is fixedly installed inside the left mounting straight groove 501, and a driving screw rod 502 is movably installed inside the right mounting straight groove 501, and a sliding platform 504 is movably installed outside the driving screw rod 502 and the guide round rod 503, and the sliding platform 504 is threadedly matched with the driving screw rod 502, and the sliding platform 504 is fixedly connected to the horizontal slide rail 401. When the driving screw rod 502 rotates around its own axis, the sliding platform 504 will move forward and backward. A scale ruler 505 is fixedly installed on the left side of the mounting base 1, and a marking protrusion 506 is arranged on the outer side of the sliding platform 504. When the sliding platform 504 moves forward and backward, the marking protrusion 506 will move synchronously.
[0023] More specifically, the clamping assembly 408 includes a telescopic round rod fixedly mounted on the cutting platform 2, and a clamping rubber block is fixedly mounted on the upper end of the telescopic round rod. When the telescopic round rod contracts, the clamping rubber block moves downward and contacts the sheet silicone 3, thereby limiting the corners of the sheet silicone 3.
[0024] In this embodiment, when in use, the staff will first spread the sheet silicone 3 flat on the cutting platform 2, and then the telescopic round rod inside the clamping assembly 408 will shrink downward, so that the clamping rubber block contacts the sheet silicone 3, thereby fixing the position of the sheet silicone 3 to prevent the sheet silicone 3 from shifting during the cutting process.
[0025] Subsequently, the sliding platform 504 will move back and forth along the mounting straight groove 501 under the action of the driving screw 502. When the sliding platform 504 moves, the horizontal slide rail 401 and the marking protrusion 506 will slide synchronously. When the marking protrusion 506 slides, the staff can determine the cutting width of the sheet silicone 3 based on the positional relationship between the marking protrusion 506 and the scale ruler 505.
[0026] After the cutting position is determined, the staff will first press the sliding rod 405 downward to make the cutting blade 406 contact the sheet silicone 3, and then push the sliding rod 405 horizontally to move it horizontally, thereby completing the cutting operation.
[0027] After the cutting is completed, the sliding rod 405 will move upward under the action of the return spring 407, so that the cutting blade 406 is out of contact with the sheet of silicone 3.
[0028] This embodiment sets a quick cutting mechanism 4, and utilizes the mutual cooperation between the sliding protrusion 403 and the cutting blade 406 to automatically cut the sheet silicone 3. Moreover, before the cutting process, the pressing rubber block will press and limit the corners of the sheet silicone 3 under the action of the telescopic round rod to avoid wrinkles on the sheet silicone 3 during the cutting process, which can effectively improve the accuracy of the cutting operation. In addition, this embodiment sets a fixed-length auxiliary mechanism 5, and utilizes the mutual cooperation between the sliding platform 504 and the driving screw 502 to automatically adjust the position of the horizontal slide rail 401 forward and backward. During the adjustment process, the staff can accurately determine the cutting width based on the positional relationship between the marking protrusion 506 and the scale ruler 505, which can not only improve the cutting efficiency but also ensure the accuracy of the cutting process.
[0029] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
