[0020] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0021] like Figures 1-4 As shown, the carrier sheet cutting device provided in this embodiment includes a workbench 1, a support 2 is provided on the top of the workbench 1, and three cylinders 3 are fixedly connected to the top of the support 2. The bottom telescopic rods of the three cylinders 3 are threadedly connected to a fixed seat 4.

[0022] Furthermore, the top two sides of the workbench 1 are provided with connecting grooves, and the inside of the connecting grooves is wrapped around the bottom of the support 2. The right side of the support 2 has three through holes, and the inside of the three through holes is a threaded rod 11. The left and right ends of the threaded rod 11 are threadedly connected with flange nuts.

[0023] The threaded rods 11 are all inserted through the bracket 2 and the worktable 1. The two ends of the threaded rods 11 are threaded and connected to flange threads. Since the overall weight of the bracket 2 is relatively large, the threaded rods 11 are inserted through the bracket to provide good support for the bracket 2. When the flange nuts at both ends of the threaded rods 11 fall off, the weight of the bracket 2 presses down on the threaded rods 11 to prevent them from falling off. The cylinder 3 is stable during operation. In the prior art, bolts are inserted through the bracket 2 and the threaded end of the bolt is threaded and connected to the worktable 1. This connection method will cause the bolts to loosen during long-term operation of the cylinder 3. Once the bolts come off, the bracket 2 will detach from the worktable 1, causing a safety accident.

[0024] Furthermore, the bottom of the fixed base 4 is connected to the cutter 5 by two sets of bolts. The front surface of the cutter 5 is fixedly provided with a set of fixed brackets 501. The top of the fixed brackets 501 is connected to the sliding brackets 502 by two sets of flange bolts. The bottom of the sliding brackets 502 is penetrated by three sets of sliding rods 503. The outside of the three sets of sliding rods 503 is penetrated by springs 504. The top of the sliding brackets 502 is penetrated by three sets of flange bolts. The bottom of the three sets of flange bolts 2 is threadedly connected to the top of the three sets of sliding rods 503. The bottom of the three sets of sliding rods 503 is connected to three connecting blocks 505 by three sets of flange bolts 3.

[0025] Each of the three connecting blocks 505 has a protective plate 506 connected to its front surface by three flange bolts, and a buffer pad is provided at the bottom of the protective plate 506.

[0026] Three cylinders 3 are activated, which drive the cutter 5 to move upward through the fixed base 4, drive the sliding frame 502 to move upward through the fixed frame 501, and drive the guard plate 506 to move through the slide rod 503 and the connecting block 505. When the cutter 5 cuts the material, the cylinder 3 drives the cutter 5 to move downward. At this time, the bottom of the guard plate 506 will press against the top of the material. When the cutter 5 cuts, the sliding frame 502 will move downward along the outside of the slide rod 503. The guard plate 506 can block the blade of the cutter 5 to prevent the worker's hand from being cut while cutting the material. When the cutter 5 moves upward, the spring 504 outside the slide rod 503 can push the sliding frame 502 to move upward.

[0027] Furthermore, three sliding grooves are provided at the top and rear ends of the worktable 1, and a lead screw 8 is rotatably connected inside each of the three sliding grooves. The rear end of the lead screw 8 extends through to the outside of the worktable 1, and the rear end of the worktable 1 is connected to the rear end of the lead screw 8 through a corresponding servo motor 9.

[0028] Furthermore, a set of stops 10 is provided on the top of each workbench 1, and a push plate 7 is surrounded by a support frame 6 at the rear end of the top of the workbench 1. The bottom of the push plate 7 is slidably connected to the inside of the slide groove through a slider, and the lead screw 8 is screwed into the internal thread of the slider.

[0029] Place the material to be cut inside the support frame 6. The stop block 10 can keep the material aligned. Start the servo motor 9 to drive the lead screw 8 to rotate inside the slide. The slider is screwed to the outside of the lead screw 8, so that the slider slides along the inside of the slide. The sliding slider can drive the push plate 7 to push the material placed on the top of the worktable 1 to the bottom of the cutter 5.

[0030] The bottom of the workbench 1 is equipped with two sets of support rods, and the bottom of the two sets of support rods is provided with a hidden groove, and a hidden universal wheel is connected inside the hidden groove.

[0031] The worktable 1 can be moved by the concealed universal casters, thus maintaining the aesthetic appearance of the worktable 1.
