Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1 , 2 , 3, 4, and 5. The present invention provides a technical solution: a trimming device for silicone ring production, including: an equipment rack 1 made of a U-shaped metal rack; a power box 2 fixedly connected to the middle of the equipment rack 1. The power box 2 is an iron box, and a lifting part is installed inside the power box 2. The output end of the lifting part is installed with a lifting pressure plate 5, and a plurality of cutting rings 16 are installed at the bottom of the lifting pressure plate 5; a support box 6 is fixedly connected to the inside of the equipment rack 1. A second support plate 9 and a first support plate 8 are slidably arranged on the top of the support box 6. Driving parts for driving the first support plate 8 to lift and move are arranged on both sides of the support box 6. When the first support plate 8 and the second support plate 9 approach each other, the first support plate 8 rises and moves horizontally, and the second support plate 9 moves from the bottom of the first support plate 8.

[0024] It should be noted that the present utility model is equipped with a PLC controller and an operation panel for operation. In the initial state, the first support plate 8 and the second support plate 9 are both placed on the top of the support guide rail 7, with the same height, and the first support plate 8 is located at the end close to the operator. The silicone rings to be adhered to each other are placed on the top of the first support plate 8, and its start is controlled by a foot switch. The driving part drives the first support plate 8 to rise, so that the height of its bottom is higher than the top height of the second support plate 9. Then, the driving part drives the first support plate 8 to move horizontally towards the bottom of the lifting pressing plate 5. At the same time, the second support plate 9 moves from the bottom of the first support plate 8 towards the operator's end, so as to realize the position exchange between the first support plate 8 and the second support plate 9. When the first support plate 8 is located below the lifting pressing plate 5, the driving part drives the first support plate 8 to descend and be placed on the top of the support guide rail 7. At the same time, the lifting part drives the lifting pressing plate 5 to move downward, so that the cutting ring 16 cuts the silicone ring. During cutting, the second support plate 9 is loaded. In this way, the first support plate 8 and the second support plate 9 are alternately placed below the lifting pressing plate 5, realizing reciprocating cutting, alternating up and down, and reducing the floor area occupied by the equipment.

[0025] Please refer to Figure 1 、 2 As shown in the figure, the lifting part is a hydraulic cylinder 4. The output end of the hydraulic cylinder 4 is fixedly connected to the lifting pressing plate 5. Two limiting rods 3 are symmetrically and fixedly connected to the top of the lifting pressing plate 5. The limiting rods 3 are slidably connected to the power box 2.

[0026] It should be noted that the hydraulic cylinder 4 of the present utility model is fixedly connected inside the hydraulic cylinder 4. The piston end of the hydraulic cylinder 4 passes through the bottom of the power box 2. The limiting rods 3 on the top of the lifting pressing plate 5 are slidably connected to the power box 2 through linear bearings. Through the limiting function of the limiting rods 3, the stable lifting of the lifting pressing plate 5 can be ensured.

[0027] Please refer to Figure 4 As shown in the figure, a sliding plate 17 is slidably connected inside the cutting ring 16. A spring 18 is fixedly connected to the top of the sliding plate 17.

[0028] It should be noted that the cutting ring 16 of the present utility model is an annular cutter. After the downward cutting is completed, when the lifting pressing plate 5 is lifted upward, the spring 18 pushes the sliding plate 17 downward, and the sliding plate 17 pushes the material inside the cutting ring 16 down.

[0029] Please refer to Figure 1 、 2 As shown in Figures 2 and 3, two support guide rails 7 are fixedly connected to the top of the support box 6. The support guide rails 7 are slidably connected to the second support plate 9. A second air cylinder 15 is fixedly connected inside the support box 6. The output end of the second air cylinder 15 is fixedly connected to the second support plate 9. Placement plates 10 are installed on the tops of both the first support plate 8 and the second support plate 9.

[0030] It should be noted that when the position of the second support plate 9 needs to be adjusted in the present utility model, the second cylinder 15 drives the second support plate 9 to slide on the top of the support guide rail 7. A chute is provided in the middle of the support box 6, and a slider is slidably connected to the middle of the chute. The top of the slider is fixedly connected to the second support plate 9, and the bottom of the slider is fixedly connected to the output end of the second cylinder 15. The support guide rail 7 supports the second support plate 9. When the lifting pressing plate 5 cuts and trims downward, the stability of the second support plate 9 can be ensured. The placing plate 10 is provided with positioning grooves corresponding to the cutting rings 16, which is convenient for positioning the silicone rings.

[0031] Please refer to Figure 2 As shown in the figure, the driving part includes mounting boxes 13 slidably arranged on both sides of the support box 6. Slide guide rails 11 are fixedly connected to the outside of the support box 6, and the mounting boxes 13 are slidably connected to the slide guide rails 11. A first cylinder 12 is fixedly connected to the outside of the support box 6, and the output end of the first cylinder 12 is fixedly connected to the mounting box 13. Two double-acting cylinders 14 are fixedly connected to the inside of the mounting box 13, and the output ends of the double-acting cylinders 14 are fixedly connected to the first support plate 8.

[0032] It should be noted that when the positions of the first support plate 8 and the second support plate 9 are swapped in the present utility model, the double-acting cylinder 14 drives the first support plate 8 to rise, and the first cylinder 12 drives the mounting box 13 to move along the slide guide rail 11 towards one end. The mounting box 13 drives the double-acting cylinder 14 and the first support plate 8 to move downward relative to the lifting pressing plate 5. At the same time, the second cylinder 15 drives the second support plate 9 to pass through from the bottom of the first support plate 8, so as to achieve the position swap. When the second support plate 9 reaches below the lifting pressing plate 5, the double-acting cylinder 14 drives the first support plate 8 to descend, so that the bottom of the first support plate 8 contacts the top of the support guide rail 7, and the support guide rail 7 provides support for the second support plate 9.

[0033] Please refer to Figure 3 As shown in the figure, a permanent magnet 20 is fixedly connected to the side of the first support plate 8, and a Hall sensor 19 cooperating with the permanent magnet 20 is fixedly connected to the inside of the equipment frame 1.

[0034] It should be noted that two Hall sensors 19 are provided in the present utility model, and the two Hall sensors 19 are respectively located in the middle and at the end of the equipment frame 1. When the first support plate 8 moves to the middle position, the permanent magnet 20 corresponds to the Hall sensor 19 in the middle, and the controller controls the double-acting cylinder 14 to drive the first support plate 8 to rise. At this time, the first support plate 8 and the second support plate 9 are staggered up and down. When the permanent magnet 20 on one side of the first support plate 8 contacts the Hall sensor 19 at the end, the double-acting cylinder 14 drives the first support plate 8 to descend. At the same time, the hydraulic cylinder 4 drives the lifting pressing plate 5 to move downward to achieve cutting and trimming.
