[0023] Specifically, the buffer lifting device 3 includes a bottom frame 31, a damper 33, a support plate 34, an elastic rubber frame 35, a lifting assembly 36 and a support column 37. The bottom frame 31 is arranged below the frame body 1, and the support plate 34 is arranged on the inner side of the bottom frame 31. A support column 37 is installed between the support plate 34 and the frame body 1. An elastic rubber frame 35 is installed between the outer bottom surface of the support plate 34 and the inner bottom surface of the bottom frame 31. A plurality of dampers 33 are installed between the outer bottom surface of the support plate 34 and the inner bottom surface of the bottom frame 31 and at a position inside the elastic rubber frame 35. The two baffle assemblies 8 are connected to the support plate 34 through the lifting assembly 36.

[0024] By adopting the above technical solution, the device can buffer external vibration to a certain extent through the cooperation of the damper 33 and the elastic rubber frame 35 when necessary, thereby reducing the possibility that the clamping work is adversely affected by external vibration.

[0025] Specifically, the buffer lifting device 3 further includes screws 32 , and two screws 32 are threadedly mounted on the top of the bottom frame 31 .

[0026] By adopting the above technical solution, the staff can fix the relative position between the bottom frame 31 and the support plate 34 by two screws 32 when necessary, thereby preventing the buffering work from being carried out and better meeting the work needs in different situations.

[0027] Specifically, the lifting assembly 36 includes a first electric telescopic rod 361 and a lifting frame 362 . The lifting frame 362 is installed outside the two baffle assemblies 8 and outside the frame 1 .

[0029] When this embodiment is used, when the device needs to be used for clamping during the discharge process of the acrylic plate, the staff starts the first electric telescopic rod 361 in the lifting assembly 36 in the buffer lifting device 3, thereby driving the lifting frame 362 to move, and then adjusting the height of the two baffle assemblies 8, and operating the conveyor belt 2 on the frame body 1 to convey the acrylic plate. The electric cylinder 5 on the cutting frame 7 can be operated to drive the cutting knife 6 to cut the acrylic plate, and then the acrylic plate can be clamped by the two baffle assemblies 8. If it is necessary to buffer the external vibration, the staff can unscrew the two screws 32, and then buffer the external vibration through the damper 33 and the elastic rubber frame 35 between the inner bottom surface of the bottom frame 31 and the outer bottom surface of the support plate 34, and the support column 37 plays a supporting role.

[0030] Example 2

[0031] The difference between this embodiment and embodiment 1 is that the cleaning device 4 includes a second electric telescopic rod 41, an air supply frame 42 and a fan 43, the second electric telescopic rod 41 is installed above the lifting frame 362, the air supply frame 42 is installed on the outside of the second electric telescopic rod 41, and a plurality of fans 43 are installed above the air supply frame 42.

[0032] By adopting the above technical solution, the device can clean the debris adhered to the two baffle assemblies 8 and the conveyor belt 2 and other structures through the cooperation of the fan 43 and the air supply frame 42 when necessary, thereby reducing the possibility of the clamping work being adversely affected.

[0033] Specifically, the cleaning device 4 further includes a partition net 44 , and the partition net 44 is installed above the air inlet end of the fan 43 .

[0034] By adopting the above technical solution, the device can prevent external impurities from entering the interior of the fan 43 through the partition net 44, thereby reducing the possibility of accidental damage to the internal structure of the fan 43, thereby ensuring normal operation.

[0035] When this embodiment is used, when it is necessary to clean the debris adhered to the structures such as the two baffle assemblies 8 and the conveyor belt 2, the fans 43 and the second electric telescopic rod 41 in the cleaning device 4 are started, and the fans 43 send the air filtered by the partition net 44 into the air supply frame 42, and then the air is blown out from the bottom of the air supply frame 42, and the second electric telescopic rod 41 drives the air supply frame 42 to move up and down, so as to blow away the debris adhered to the structures such as the two baffle assemblies 8 and the conveyor belt 2, and then clean the debris adhered to the structures such as the two baffle assemblies 8 and the conveyor belt 2.

[0036] The structure and principle of the conveyor belt 2, the cutting frame 7, and the baffle assembly 8 composed of a rotating shaft, a pulley, a belt, a baffle, a slide groove 1, an electromagnet, a push switch, a spring, a clamping plate, a mounting frame, a slide groove 2, a bevel gear 1, a bevel gear 2, a cam, a movable frame and a slot in the utility model have been disclosed in a clamping device for discharging acrylic plates disclosed in Chinese patent application No. 202121956456.7. Its working principle is to send the acrylic plate to the middle of the cutting frame for cutting. The mass of the acrylic plate after cutting is reduced. In order to prevent the acrylic plate from being unstable during transportation, after cutting, the acrylic plate will contact the baffle on one side, and on both sides of the conveyor belt on one side of the cutting frame. A mounting frame is fixed, and the interior of the mounting frame drives the pulley to rotate through a rotating shaft. A belt is connected to the outer side of the pulley for transmission. Blocking pieces are evenly fixed on the belt, and the blocking pieces extend above the conveyor belt. The blocking pieces move with the belt. When the acrylic plate contacts the blocking piece, the pressing switch on the blocking piece will be squeezed. An electromagnet was originally fixed on one side of the blocking piece, and the electromagnet sucked the iron splint. When the pressing switch is squeezed, the electromagnet is closed, and the splint that loses attraction pops out under the action of the spring in the middle, clamping the side of the acrylic plate. A sponge strip is set at the contact position between the splint and the acrylic plate to prevent damage to the acrylic plate. The conveyor belt still drives the acrylic plate to move, and the clamped blocking piece is moved by the conveyor belt The acrylic plate on the cutting frame is driven to move, so that the belt moves and the pulley is driven to rotate. By clamping the two sides of the acrylic plate, the movement of the acrylic plate after cutting and discharging is more stable, so that the acrylic plate will not shake during transportation; the acrylic plate after cutting will be rotated by the conveyor belt to move the acrylic plate. A moving frame is arranged at the bottom of the conveyor belt on one side of the cutting frame. The two sides of the moving frame are slidably connected with the slots. A cam is arranged at the bottom of the slot. The cam and the moving frame contact each other and are driven to rotate by the conveyor belt through the rotating shaft in the middle of the mounting frame, driving the bevel gear 1 at the bottom of the rotating shaft, so that the bevel gear 1 is meshed with the bevel gear 2 on the outside. The bevel gear 2 is coaxial with one side. The cam will also rotate accordingly, causing the cam to drive the moving frame to rise and fall. The moving frame is driven by the cam to rise and fall back and forth. When the push plate on the top of the moving frame rises, it will contact the acrylic plate moving on the top of the conveyor belt. At the beginning, the moving frame is at the highest point, and the acrylic plate that has just been contacted will be lifted up. After the position is lifted up, one side of the acrylic plate is lifted up and clamped by the baffle, so that only one side of the acrylic plate moves on the conveyor belt. As the baffle is driven by the acrylic plate to move, the rotating shaft rotates to drive the bevel gear 1 at the bottom to mesh with the bevel gear 2, so that the cam lifts the moving frame back and forth, so that one side of the acrylic plate will be lifted up, reducing the friction between the acrylic plate and the conveyor belt, and ensuring the quality of the acrylic plate.

[0037] The structure and principle of the damper 33 in the utility model have been disclosed in a smart home washing machine shock absorbing device disclosed in Chinese Patent Application No. 201721446985.6. Its working principle consists of a piston and an oil tank, which is filled with oil. When the object moves, the piston moves in the oil, thereby consuming energy and slowing down the movement of the object.

[0038] The working principle and use process of the utility model are as follows: when the device needs to be used for clamping during the discharge process of the acrylic plate, the staff starts the first electric telescopic rod 361 in the lifting assembly 36 in the buffer lifting device 3, thereby driving the lifting frame 362 to move, and then adjusting the height of the two baffle assemblies 8, operating the conveyor belt 2 on the frame body 1 to convey the acrylic plate, and operating the electric cylinder 5 on the cutting frame 7 to drive the cutting knife 6 to cut the acrylic plate, and then clamping the acrylic plate through the two baffle assemblies 8. If it is necessary to buffer the external vibration, the staff can unscrew the two screws 32, and then through the inner bottom surface of the bottom frame 31 and the outer bottom surface of the support plate 34. The damper 33 and the elastic rubber frame 35 between them can buffer the external vibration, and the support column 37 plays a supporting role; when it is necessary to clean the debris adhered to the two baffle assemblies 8 and the conveyor belt 2 and other structures, the fans 43 and the second electric telescopic rod 41 in the cleaning device 4 are started, and each fan 43 sends the air filtered by the partition net 44 into the air delivery frame 42, and then the air is blown out from the bottom of the air delivery frame 42, and the second electric telescopic rod 41 drives the air delivery frame 42 to move up and down, so as to blow away the debris adhered to the two baffle assemblies 8 and the conveyor belt 2 and other structures, and then clean the debris adhered to the two baffle assemblies 8 and the conveyor belt 2 and other structures.
