The four support rods 11 are fixedly connected to the top of the base 1, the connecting plate 12 is fixedly connected between the four support rods 11, the hydraulic press 13 is fixedly connected above the connecting plate 12, and the cutter 14 is fixedly connected to the lower end of the piston rod of the hydraulic press 13. Extrusion blocks are arranged on the front and rear sides of the knife 14, and the cutter 14 is used to cut the graphene plate 113. The chassis 15 is fixedly connected to the top of the base 1, and the mold 16 is fixedly connected to the top of the chassis 15. Two slide grooves are arranged on the right side of the mold 16. Two groups of first sliding rods 19 symmetrically arranged front and back are fixedly connected to the base 1, and each group of first sliding rods 19 includes two first sliding rods 19. The lower pressing rods 17 are respectively slidably connected to each group of first sliding rods 19, and the lower pressing rods 17 are pressed and matched with the extrusion blocks on the cutter 14. The lower pressure rod 17 slides in the slide groove on the right side of the mold 16, and the first sliding rod 19 is wound with a return spring 18, one end of the return spring 18 is fixedly connected to the lower pressure rod 17, and the other end of the return spring 18 is fixedly connected to the base 1, and the two gear frames 112 are fixedly connected to the right side of the base 1, and the gear frames 112 are symmetrically arranged front and back, and the gear frames 112 are fixedly connected with limit blocks symmetrically arranged left and right, and the support plates 110 are rotatably connected to the inner side of the gear frames 112, and the support plates 110 and the gear frames 1 The limit block on 12 is squeezed and fitted, and the limit block is used to limit the support plate 110. The left and right ends of the gear frame 112 are wound with torsion springs 111, one end of the torsion spring 111 is fixedly connected to the support plate 110, and the other end of the torsion spring 111 is fixedly connected to the gear frame 112. The graphene plate 113 is placed between the support plates 110 that are symmetrically arranged front and back, and the collection box 114 is placed on the ground. The collection box 114 is located directly below the graphene plate 113, and the collection box 114 is used to collect the graphene plate 113.

[0034] In the production process of the graphene plate 113, in order to meet the needs of different sizes and adapt to the subsequent processing procedures, the graphene plate 113 needs to be cut. When the graphene plate 113 is cut, the cut graphene plate 113 will fall directly to the ground, which is easy to be worn by the ground, affecting the product quality. In addition, the cut graphene plate 113 will be scattered on the ground in a disorderly manner, and the staff needs to collect and sort it. When people need to cut the graphene plate 113, they can use this device to operate. The working principle of this device is as follows: first, the hydraulic press 13 is controlled to make the cutter 1 4 moves downward, the cutter 14 moves downward to cut the graphene plate 113, and the cut graphene plate 113 falls onto the support plate 110. In the process of the cutter 14 moving downward to cut the graphene plate 113, the extrusion block of the cutter 14 will squeeze the pressing rod 17. Under the extrusion of the extrusion block, the pressing rod 17 will move downward, and the return spring 18 will be compressed. The pressing rod 17 moves downward to squeeze the support plate 110. Under the extrusion of the pressing rod 17, the support plate 110 will rotate downward, and the torsion spring 111 will gradually accumulate force, because at this time the cut graphene plate 113 is just The support plate 110 is placed on the support plate 110, and the support plate 110 rotates downward and no longer supports the graphene plate 113. The graphene plate 113 moves downward under the action of its own gravity, and the graphene plate 113 moves downward and falls into the collection box 114. After the cutter 14 moves downward to cut the graphene plate 113, the hydraulic press 13 drives the cutter 14 to move upward and reset. The cutter 14 moves upward and disengages from the pressing rod 17. The extrusion block of the cutter 14 no longer squeezes the pressing rod 17. At this time, the compressed reset spring 18 stretches, and the elongation of the reset spring 18 drives the pressing rod 17 to move upward and reset. 7 moves downward and no longer presses the support plate 110, the torsion spring 111 in the power storage state will be converted into a pressure release state, and the torsion spring 111 will drive the support plate 110 to rotate upward and reset, and repeat the above operation to continuously cut the graphene plate 113 and drive the support plate 110 to rotate, so that the cut graphene plate 113 falls into the collection box 114. In this way, the cut graphene plate 113 can be supported and made to fall straight and smoothly into the collection box 114, thereby realizing the collection and arrangement of the cut graphene plates 113 and avoiding the wear of the graphene plates 113 by the ground.

[0035] Embodiment 2: Based on embodiment 1, Figure 5 and Figure 6As shown, it also includes a pushing mechanism for smoothly pushing out the plate, the pushing mechanism includes a roller 2, a gear 21, a rack 22, a return spring 23 and a limiting rod 24, the roller 2 is rotatably connected to the right side of the chassis 15 through a rotating shaft, the gear 21 is fixedly connected to the front side of the rotating shaft of the roller 2, the two limiting rods 24 are fixedly connected to the upper front position of the base 1, the rack 22 is slidably connected between the two limiting rods 24, the rack 22 is squeezed and matched with the downward pressure rod 17 located in the front, the rack 22 and the gear 21 are meshed with each other, the return springs 23 are all wound on the limiting rods 24, one end of the return spring 23 is fixedly connected to the rack 22, and the other end of the return spring 23 is fixedly connected to the limiting rod 24.

[0036] When the cutter 14 cuts the graphene plate 113, the cut graphene plate 113 may still be adhered to the uncut graphene plate 113, so that the cut graphene plate 113 cannot be completely separated from the uncut graphene plate 113. Therefore, it is necessary to set a pushing mechanism to push the cut graphene plate 113 to separate it from the uncut graphene plate 113. The working principle of the pushing mechanism is as follows: when the cutter 14 moves downward to cut the graphene plate 113, the pressing rod 17 will also move downward. The downward movement of the pressing rod 17 will squeeze the rack 22. Under the squeezing action of the pressing rod 17, the rack 22 will move downward, and the return spring 23 will be compressed. When the rack 22 moves downward, it will drive the gear 21 to rotate clockwise, and the rotation of the gear 21 will drive the roller 2 As the rotating shaft rotates, the roller 2 will also rotate clockwise, and the clockwise rotation of the roller 2 will push the cut graphene plate 113 to move to the right. The cut graphene plate 113 moving to the right will be separated from the uncut graphene plate 113, so that the two will no longer be adhered to each other, and the graphene plate 113 can smoothly fall into the collection box 114. When the cutter 14 moves upward, the pressing rod 17 will also move upward. The pressing rod 17 moves upward and no longer squeezes the rack 22. At this time, the compressed return spring 23 will extend, and the extension of the return spring 23 will drive the rack 22 to move upward and reset, so that the cut graphene plate 113 can be pushed to the right, and the cut graphene plate 113 will be completely separated from the uncut graphene plate 113, so that the graphene plate 113 can smoothly fall into the collection box 114.

[0037] like Figure 7 and Figure 8As shown, it also includes a clamping mechanism for clamping the collection box 114, the clamping mechanism includes a limiting frame 3, a connecting spring 31 and a second sliding rod 32, the limiting frames 3 symmetrically arranged front and back are all slidably connected to the lower right side of the base 1, the front and rear inner sides of the lower right side of the base 1 are fixedly connected to the second sliding rod 32, the second sliding rod 32 is slidably connected to the limiting frame 3, the connecting springs 31 are all wound on the second sliding rod 32, one end of the connecting spring 31 is fixedly connected to the limiting frame 3, and the other end of the connecting spring 31 is fixedly connected to the base 1.

[0038] When the cut graphene plate 113 falls into the collecting box 114, the graphene plate 113 may squeeze the inner wall of the collecting box 114, and the collecting box 114 will be displaced due to the squeezing of the graphene plate 113. Therefore, a clamping mechanism is required to clamp the collecting box 114. When the cut graphene plate 113 falls downward and squeezes the collecting box 114, the collecting box 114 will squeeze the limiting frame 3 on one side. Under the squeezing action of the collecting box 114, the limiting frame 3 on one side will move outward a short distance, and the connecting spring 31 on the same side will be slightly compressed. Under the action of the elastic force of the connecting spring 31, the limiting frame 3 will only be slightly displaced, so that the collecting box 114 will also only be displaced a small distance. In this way, the collecting box 114 can be stabilized, so that the cut graphene plate 113 can fall smoothly into the collecting box 114.

[0039] like Figure 9-11As shown, it also includes a cleaning mechanism for cleaning debris, the cleaning mechanism includes a sliding groove 4, a cleaning plate 41, a locking rod 42, a compression spring 43, a pressing piece 44, a latch 45 and a linear spring 46, the rear pressing rod 17 is slidably connected with the latch 45, the linear spring 46 is wound on the latch 45, one end of the linear spring 46 is fixedly connected to the latch 45, the other end of the linear spring 46 is fixedly connected to the rear pressing rod 17, the pressing piece 44 is rotatably connected to the rear side of the rear pressing rod 17, the pressing piece 44 is snap-fitted with the latch 45, the pressing piece 44 is squeezed with the inclined surface below the rear of the latch 45, two third sliding rods 47 are slidably connected to the right side of the base 1 near the chassis 15, the third sliding rod 47 It is symmetrically arranged front to back, the third sliding rod 47 at the rear is longer, the compression springs 43 are respectively wound on the third sliding rods 47, and the sliding groove 4 is fixedly connected between the two third sliding rods 47. Because the third sliding rod 47 at the rear is longer, the sliding groove 4 is tilted downward in the front and lifted upward in the back. A clamping hole is opened at the upper rear of the sliding groove 4, and the pressing piece 44 is squeezed and matched with the clamping hole on the sliding groove 4. The compression springs 43 are all wound on the third sliding rod 47, one end of the compression spring 43 is fixedly connected to the base 1, and the other end of the compression spring 43 is fixedly connected to the sliding groove 4, the locking rod 42 is fixedly connected to the right side of the chassis 15, and the cleaning plate 41 is slidably connected to the locking rod 42, and the cleaning plate 41 is slidably connected to the sliding groove 4.

[0040] Before the cutter 14 cuts the graphene plate 113, it is usually necessary to cut off a small portion of graphene debris for knife testing, and some graphene debris will also be generated during the cutting process. The cut debris will fall to the right side of the mold 16, and the debris will be located above the chassis 15. Because the location where the debris falls is close to the cutter 14, when the staff needs to clean the debris, it is necessary to turn off the cutting device to ensure the safety of the staff, which will increase the idle time of the machine tool and reduce the proportion of the effective use time of the machine tool. Moreover, this location is close to the interior, and it is difficult for the staff to completely clean out the debris. Therefore, a cleaning mechanism is required to clean out the debris. The working principle of the cleaning mechanism is as follows: Fig.11As shown, before the cleaning mechanism cleans the debris, the pressing member 44 is locked by the latch 45. When the debris needs to be cleaned, the staff needs to pull the latch 45 forward, the linear spring 46 will extend, the latch 45 moves forward and no longer blocks the pressing member 44, and the pressing member 44 will rotate downward due to gravity. After the pressing member 44 rotates downward, the staff can stop pulling the latch 45, the extended linear spring 46 will shrink, and the shrinkage of the linear spring 46 will drive the latch 45 to move backward and reset, and the pressing member 44 rotates downward so that the bottom end of the pressing member 44 is located above the locking hole at the rear end of the sliding slot 4. As described above, when the cutter 14 When the graphene plate 113 is cut by moving downward, the pressing rod 17 will also move downward, and the pressing rod 17 will drive the pressing member 44 to move downward. The pressing member 44 will contact and squeeze the card hole at the rear end of the sliding groove 4. Under the squeezing action of the pressing member 44, the sliding groove 4 will move downward. At this time, the compression spring 43 is compressed, and the sliding groove 4 will squeeze the cleaning plate 41 when it moves downward. Under the squeezing action of the sliding groove 4, the cleaning plate 41 will move backward. The cleaning plate 41 will move backward and push the debris on the chassis 15 to the upper rear of the base 1. In this way, the staff can directly clean the debris on the upper rear of the base 1. After cutting the graphene plate 113, the cutter 14 will move upward, and the pressing rod 17 will also move upward. The upward movement of the pressing rod 17 will drive the pressing member 44 to move upward as well. The pressing member 44 moves upward and no longer squeezes the sliding groove 4. At this time, the compressed compression spring 43 will extend. The extension of the compression spring 43 will drive the sliding groove 4 to move upward and reset. The upward movement of the sliding groove 4 will squeeze the cleaning plate 41. Under the squeezing action of the sliding groove 4, the cleaning plate 41 will move forward and reset. After the upward movement and reset of the pressing rod 17 is completed, the staff can rotate the sliding groove 4 upward. The upward rotation of the sliding groove 4 will squeeze the lower part behind the latch 45. The inclined surface, under the squeezing action of the sliding groove 4, the pin 45 will move forward, and the linear spring 46 will extend. When the lower pressing piece 44 rotates upward to the top of the pin 45, the lower pressing piece 44 no longer squeezes the pin 45, and the extended linear spring 46 will shrink. The contraction of the linear spring 46 will drive the pin 45 to move backward and reset. The movement of the pin 45 to the right will re-lock the lower pressing piece 44. When a lot of graphene debris accumulates on the right side of the mold 16, the above operation can be repeated to clean the debris. Through the above operation, the graphene debris on the right side of the mold 16 can be pushed to the upper rear of the base 1, which is convenient for the staff to clean the debris.
