At the same time, it also avoids the situation where the clamping plates move towards each other and rise at the same time when clamping due to the small size of the plates.

The transmission assembly includes four sprocket wheels 16, and the four sprocket wheels 16 are fixedly connected to the bottom end of the first reciprocating screw rod 3. , the four sprockets 16 are connected by a chain 17 to keep the four first reciprocating screw rods 3 running synchronously, one of the first reciprocating screw rods 3 is coaxially fixedly connected to a servo motor 18 at the bottom end, a plurality of limit holes are provided on one side of the first rack 7 and the second rack 8, and a limit pin 19 is slidably connected inside the limit hole to limit the position after adjusting the rack length, the meshing teeth on the second rack 8 and the first rack 7 are in the same horizontal plane and meshed with the transmission gear 6. When the plate is stored at a higher level, it is necessary to raise the plate. During the rising process, an electric push rod is used in the prior art to clamp and limit the two ends of the plate to prevent the plate from falling and causing damage to the plate, but a controller is required to control the operation of the electric push rod, which complicates the operation of the device and reduces the The linkage of the device is not practical enough. When the plate needs to be loaded to a higher position, the plate is first placed on the support block 15, and the servo motor 18 is turned on to drive one of the first reciprocating screws 3 to rotate. The four first reciprocating screws 3 are synchronously rotated through the transmission between the sprocket 16 and the chain 17, and the first moving block 4 is raised while rotating. The transmission gear 6 on the outer side of the rotating rod 5 on one side of the fixed plate 12 on the first moving block 4 is meshed and connected to the first rack 7 and the second rack 8, so that the rotating rod 5 is driven to rotate while rising. At this time, the rotation of the rotating rod 5 drives the first bevel gear and the second bevel gear 10 to rotate, so that the second moving block 13 on the second reciprocating screw 11 drives a pair of clamping plates 14 to clamp both sides of the plate. Due to the length of the plate,To adjust the length of the first rack 7 and the second rack 8, so that the clamping plate 14 will not continue to clamp the plate due to the rising height being too high and squeeze and damage the plate, and at the same time, it can also ensure that the plate does not deviate during the rising process, causing the plate to fall and cause damage to the plate.

[0025] A fixed rod 20 is fixedly connected between the two sides of the rectangular groove, and the outer side of the fixed rod 20 is rotatably connected to the support block 15. A limit rod 21 is fixedly connected between the two sides of the rectangular groove and is located above the support block 15. A feeding port 22 is opened in the middle of the workbench 1, and a fixed frame 23 is fixedly connected to the bottom end of the workbench 1. A hydraulic cylinder 24 is fixedly connected to the top of the fixed frame 23. A support plate 25 is fixedly connected to the top of the hydraulic cylinder 24. The hydraulic cylinder 24 and the support plate 25 are both located in the middle of the feeding port 22. When multiple groups of plates need to be loaded, multiple groups of loading plates are first placed on the support plate 25, and the hydraulic cylinder 24 is turned on to drive the multiple groups of plates to rise. Because the support block 15 is rotatably connected to the fixed frame 23, the hydraulic cylinder 24 is fixedly connected to the top of the fixed frame 23. The support plate 25 is fixedly connected to the top of the hydraulic cylinder 24. The hydraulic cylinder 24 and the support plate 25 are both located in the middle of the feeding port 22. On the rod 20, when multiple groups of plates rise and pass through the support block 15, the upward force from the bottom causes the four support blocks 15 to rotate upward, so that after the multiple groups of plates pass, the support block 15 rotates downward, but due to the limiting effect of the limit rod 21, the four support blocks 15 always remain in a horizontal state. At this time, the mobile hydraulic cylinder 24 moves downward to support the plates on the support block 15, and then the servo motor 18 is turned on to raise the plates to a suitable height, thereby completing the simultaneous loading of multiple groups of plates and improving work efficiency. At the same time, it also avoids the situation where the clamping plates 14 move towards each other and rise at the same time when clamping due to the small size of the plates. When it rises to a higher position, it is inconvenient for the staff to load multiple groups of plates.

[0026] Working principle: when it is necessary to load the plate to a higher position, first put the plate onto the support block 15, turn on the servo motor 18 to drive one of the first reciprocating screw rods 3 to rotate, and transmit the four first reciprocating screw rods 3 through the sprocket 16 and chain 17 to rotate synchronously, and at the same time, the first moving block 4 rises, and the transmission gear 6 on the outer side of the rotating rod 5 on one side of the fixed plate 12 on the first moving block 4 is meshed and connected to the first rack 7 and the second rack 8, so that the rotating rod 5 is driven to rotate while rising. At this time, the rotation of the rotating rod 5 drives the first bevel gear and the second bevel gear 10 to rotate, so that the second moving block 13 on the second reciprocating screw rod 11 drives a pair of clamping plates 14 to clamp both sides of the plate. Because the length of the plate is adjusted to the length of the first rack 7 and the second rack 8, the clamping plate 14 will not continue to clamp the plate due to excessive rising height and squeeze and damage the plate, and at the same time, it can also ensure that the plate is rising. In order to avoid deviation during the process, which may cause the plates to fall and cause damage to the plates, when multiple groups of plates need to be loaded, the multiple groups of loading plates are first placed on the support plate 25, and the hydraulic cylinder 24 is turned on to drive the multiple groups of plates to rise. Because the support block 15 is rotatably connected to the fixed rod 20, when the multiple groups of plates rise and pass through the support block 15, the upward force from the bottom causes the four support blocks 15 to rotate upward, so that after the multiple groups of plates pass, the support block 15 rotates downward, but due to the limiting effect of the limit rod 21, the four support blocks 15 always remain in a horizontal state, and at this time, the hydraulic cylinder 24 is moved downward to support the plates on the support block 15, and the servo motor 18 is turned on to raise the plates to a suitable height, so as to complete the simultaneous loading of multiple groups of plates and improve work efficiency. At the same time, it is also avoided that when the plates are small in size, the clamping plates 14 move towards each other and rise at the same time when clamping, and when they rise to a higher position, it is inconvenient for the staff to load multiple groups of plates.
