A rotating shaft 7 is provided inside the gantry mounting frame 2 through a driving assembly, and the rotating shaft 7 is rotatably connected to the gantry mounting frame 2. A rotating screw 8 is fixedly provided at the bottom of the rotating shaft 7, and an internally threaded tube 9 is threaded on the surface of the rotating screw 8. A movable frame 10 is fixedly provided at the bottom of the internally threaded tube 9, and a guide assembly is provided on the top of the movable frame 10. The assembly includes a guide rod 11, which is fixedly mounted on the top of the moving frame 10. The guide rod 11 is slidably arranged inside the gantry mounting frame 2. There are two guide rods 11, and the two guide rods 11 are symmetrically distributed. The guide rods 11 are made of metal material. The two guide rods 11 make the moving frame 10 move more smoothly, avoiding shaking during the movement of the moving frame 10. A mounting circular plate 12 is fixedly arranged on the top of the guide rod 11, and the bottom of the mounting circular plate 12 is fixedly arranged on the supporting spring 13. The bottom end of the supporting spring 13 is fixedly mounted on the top of the gantry mounting frame 2. During the movement of the moving frame 10, the guide rod 11 drives the mounting circular plate 12 to compress the supporting spring 13. When the internal threaded tube 9 moves downward, the internal threaded tube 9 The contact surface with the rotating screw 8 is reduced, so that the force on the thread teeth on the surface of the rotating screw 8 and the thread teeth in the internal threaded tube 9 is increased, and the rebound effect of the support spring 13 offsets a part of the force on the rotating screw 8 and the internal threaded tube 9, thereby avoiding damage to the thread teeth on the surface of the rotating screw 8 and the threads in the internal threaded tube 9 caused by excessive force. A detection component for detecting the moving component is arranged on the mounting base 1, and the detection component includes a mounting plate 14 and a moving plate 15. The mounting plate 14 is fixedly mounted on the front side of the gantry mounting frame 2, and the moving plate 15 is slidably arranged on the surface of the gantry mounting frame 2. The moving plate 15 is located on one side inside the gantry mounting frame 2 and is fixedly mounted on the front side of the moving frame 10. A laser ranging sensor 16 is fixedly arranged on the left side of the mounting plate 14.Since the reading of the laser distance sensor 16 is zero when the upper calendering roller 18 contacts the lower calendering roller 20, the distance between the upper calendering roller 18 and the lower calendering roller 20 can be controlled by the moving distance of the movable plate 15, so that the distance adjustment between the upper calendering roller 18 and the lower calendering roller 20 is more accurate, avoiding repeated adjustments and wasting time. The mounting base 1 is provided with a calendering assembly for mechanical calendering of the thermal conductive silicone gasket. The driving motor 4 drives the rotating shaft 7 to rotate through the worm 5 and the worm gear 6, so that the rotating shaft 7 drives the rotating screw 8 to rotate, so that the internal threaded tube 9 pushes the moving frame 10 to drive the upper calendering roller 18 to move, and the laser distance sensor 16 detects the moving distance of the movable plate 15, so as to control the distance between the upper calendering roller 18 and the lower calendering roller 20, so that the upper calendering roller 18 and the lower calendering roller 20 can be adjusted more accurately, avoiding the situation where the adjustment error causes the need for repeated adjustments, and during the adjustment process, the staff cannot manually adjust, so that the calender can be automatically adjusted.
[0021] Specifically, the calendering assembly includes a rotating motor 17 and a rotating motor 19. The rotating motor 17 is fixedly installed on the right side of the mobile frame 10. The output end of the rotating motor 17 passes through the mobile frame 10 and extends to the interior of the mobile frame 10 and is fixedly provided with an upper calendering roller 18. A groove for moving the rotating motor 17 is penetrated on the right side of the gantry mounting frame 2. The surface of the rotating motor 17 does not contact the inner wall of the groove. Through the setting of the groove, the situation in which the gantry mounting frame 2 blocks the rotating motor 17 and causes the upper calendering roller 18 to be unable to move is avoided. The rotating motor 19 is fixedly installed on the right side of the gantry mounting frame 2. The output end of the rotating motor 19 passes through the gantry mounting frame 2 and extends to the interior of the gantry mounting frame 2 and is fixedly provided with a lower calendering roller 20.
[0022] The fully automatic calendering machine for producing the thermally conductive silicone gasket is connected to a 220V mains power supply, and the main controller can be a conventional known device for controlling a computer or the like.
[0023] When in use: the output end of the driving motor 4 is driven to rotate the worm 5, and the worm 5 is driven to rotate the worm wheel 6 meshing with it, and the worm wheel 6 is driven to rotate the rotating shaft 7, and then the rotating screw 8 is driven to rotate by the rotating shaft 7, so that the internal threaded tube 9 moves downward along the thread direction of the surface of the rotating screw 8, so that the internal threaded tube 9 drives the moving frame 10 to move downward, and the moving frame 10 drives the guide rod 11 to move downward, so that the guide rod 11 drives the installation circular plate 12 to compress the support spring 13, and drives the rotating motor 17 and the upper calendering roller 18 to move downward through the moving frame 10, and during the movement of the moving frame 10, the moving frame 10 will drive the moving The plate 15 moves downward, and the distance moved by the movable plate 15 is measured by the laser distance sensor 16. Since the detection result of the laser distance sensor 16 is zero when the upper calendering roller 18 and the lower calendering roller 20 are in contact, the distance moved by the movable plate 15 detected by the laser distance sensor 16 is the distance between the upper calendering roller 18 and the lower calendering roller 20. After the adjustment is completed, the thermal conductive silicone gasket passes between the upper calendering roller 18 and the lower calendering roller 20, and the rotating motor 17 and the rotating motor 19 simultaneously drive the output end to drive the rotating motor 19 and the lower calendering roller 20 to rotate, so that the upper calendering roller 18 and the lower calendering roller 20 calender the thermal conductive silicone gasket.
[0024] To summarize, the fully automatic calendering machine for producing thermally conductive silicone gaskets drives the rotating shaft 7 to rotate through the driving motor 4 through the worm 5 and the worm wheel 6, so that the rotating shaft 7 drives the rotating screw 8 to rotate, so that the internal threaded tube 9 pushes the movable frame 10 to drive the upper calendering roller 18 to move, and the laser ranging sensor 16 detects the moving distance of the movable plate 15, thereby controlling the distance between the upper calendering roller 18 and the lower calendering roller 20, so that the adjustment of the upper calendering roller 18 and the lower calendering roller 20 is more accurate, avoiding the situation where the adjustment error causes repeated adjustment, and during the adjustment process, the staff cannot manually adjust, so that the calendering machine can be automatically adjusted, which is used to solve the problems raised in the above background technology.
