All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0026] The following combination Figure 1-5 The specific embodiment of the utility model is described, which is a CNC low-speed unwinding, leveling and shearing line for thick plates, comprising:

[0027] The uncoiler 1 is provided with a slide rail 11 at the bottom for its transverse sliding, so that the uncoiler 1 can slide along the slide rail 11. The position of the uncoiler 1 can be adjusted according to the different widths of the materials, so that the plate material unrolled by the uncoiler 1 is facing the leveling conveyor 2;

[0028] The leveling conveyor 2 is used to level and convey the plate unrolled by the uncoiler 1. A frame 4 is provided on one side of the uncoiler 1. The leveling conveyor 2 is installed on the frame 4. The leveling conveyor 2 includes a support plate 21. An adjustment slot 22 is provided on the support plate 21. An adjustment plate 23 is provided in the adjustment slot 22. A leveling conveying roller 26 is rotatably provided on the adjustment plate 23. The adjustment slot 22 provided on the support plate 21 is used to adjust the height of the adjustment plate 23. By adjusting the height of the adjustment plate 23, the leveling conveying roller 26 rotatably connected to the adjustment plate 23 can be changed to meet the leveling requirements of plates of different thicknesses.

[0029] The cutting machine 3 is used to cut the leveled plate. The cutting machine 3 is installed on the frame 4 and is located on one side of the leveling conveyor 2. The cutting machine 3 includes a support frame 31, which is fixedly connected to the frame 4. A cutter 37 is provided on the frame 4. A splint 34 is provided outside the cutter 37. The splint 34 is connected to the frame 4. The support frame 31 serves as a connecting piece, which is installed and connected to the top of the frame 4. A cutter 37 is connected to the support frame 31. The plate is cut by controlling the downward movement of the cutter 37. Before the cutter 37 contacts the plate, the splint 34 outside the cutter 37 contacts the plate and clamps the plate to prevent the plate from moving during cutting.

[0030] Please refer to Figure 1 As shown, the frame 4 is arc-shaped at one end close to the uncoiler 1, and a plurality of guide rollers 41 are provided on the arc circumference. The guide rollers 41 are rotatably connected to the frame 4. The guide rollers 41 guide and support the plate unfolded and conveyed in the uncoiler 1, so that the plate is conveyed to the side of the leveling conveyor 2.

[0031] Please refer to Figure 2-Figure 5 As shown, an installation space is formed in the support plate 21, and the adjustment plate 23 is located in the installation space and is slidably adapted to the adjustment slot 22. An adjustment motor 25 is fixedly provided on the support plate 21, and a screw rod 24 is provided at the output end of the adjustment motor 25. The screw rod 24 cooperates with the adjustment plate 23, and one end thereof is rotatably connected to the bottom of the support plate 21. The adjustment motor 25 drives the screw rod 24 to rotate, and the rotation of the screw rod 24 forces the screw rod 24 to cooperate with the adjustment plate 23, thereby changing the height of the adjustment plate 23 in the support plate 21, so that the adjustment plate 23 is adjusted up and down along the adjustment slot 22, and finally changes the position of the leveling conveying roller 26 on the adjustment plate 23 to adapt to the thickness requirements of different plates.

[0032] Please refer to Figure 2-Figure 4As shown, a cylinder 32 is provided on the support frame 31, and the fixed end of the cylinder 32 is fixedly connected to the support frame 31, and a lower pressure plate 33 is fixedly provided at the output end. The cutter 37 is fixedly connected to the lower pressure plate 33. The operation of the cylinder 32 drives the lower pressure plate 33 to move up and down along the height direction of the support frame 31. The cutter 37 is fixedly connected to the end of the lower pressure plate 33 away from the cylinder 32. The cutter 37 moves downward synchronously with the lower pressure plate 33, and then cuts the plate conveyed to the cutting position. The lower pressure plate 33 is symmetrically provided with mounting holes 38, and a positioning rod 35 is provided in the mounting hole 38. The positioning rod 35 is slidably connected in the mounting hole 38.

[0033] Please refer to Figure 4 As shown, one end of the positioning rod 35 is fixed with a stopper 39, and the other end of the positioning rod 35 is fixedly connected to the clamping plate 34. The clamping plate 34 is a hollow structure. A return spring 36 is provided between the lower pressure plate 33 and the clamping plate 34. The return spring 36 is sleeved on the positioning rod 35, and its two ends are respectively in contact with the lower pressure plate 33 and the clamping plate 34. When the cylinder 32 drives the lower pressure plate 33 to move downward, the clamping plate 34 first contacts the plate under the action of the return spring 36, and is released when the cylinder 32 drives the lower pressure plate 33 to move downward. 2, the sheet material being conveyed is clamped and stopped, and as the lower pressure plate 33 continues to descend, the cutter 37 is brought into contact with the sheet material to cut the sheet material. When the sheet material is cut, the clamping plate 34 is expanded and a certain distance is formed between the clamping plate 34 and the lower pressure plate 33 under the action of the return spring 36. At this time, the distance between the clamping plate 34 and the lower pressure plate 33 is greater than the distance between the bottom of the cutter 37 and the lower pressure plate 33. Since a block 39 is provided on the top of the positioning rod 35, the positioning rod 35 cannot always be separated from the mounting hole 38.

[0034] Please refer to Figure 2-Figure 4 As shown, the frame 4 is provided with a lower cutting plate 42, and the lower cutting plate 42 is fixedly connected to the frame 4. A straight slot 43 is opened on the lower cutting plate 42, and the cutter 37 is opposite to the straight slot 43. The straight slot 43 is for the cutter 37 to pass through for cutting the plate.

[0035] Please refer to Figure 1 As shown, a lift 12 is provided on the slide rail 11, and the lift 12 is slidably connected to the slide rail 11. The lift 12 is used for loading the coiled plates, wherein the lift 12 and the uncoiler 1 can both slide along the slide rail 11, and the lift 12 realizes convenient loading of the coiled plates.

[0036] Please refer to Figure 1-Figure 3As shown, a conveyor belt 44 is provided on the top of the frame 4. The conveyor belt 44 is located on the side of the cutting machine 3 away from the leveling conveyor 2. One end of the conveyor belt 44 is connected to the cutter 37 and is used for unloading the cut material.

[0037] Working principle of this utility model:

[0038] The coiled plate is located on the upper end surface of the lift 12. By moving the lift 12 along the slide rail 11 and controlling the lifting of the lift 12, the coiled plate on the lift 12 is loaded onto the uncoiler 1.

[0039] The coiled sheet is gradually unwound by the uncoiler 1 and conveyed to pass through the guide roller 41. The guide roller 41 guides the unwound sheet while conveying the sheet and guides the sheet to be conveyed to the leveling conveyor 2.

[0040] The leveling conveyor rollers 26 rotating in the leveling conveyor 2 level the plates and convey them. An adjustment slot 22 is provided on the support plate 21. An adjustment plate 23 is provided in the adjustment slot 22 and can be adjusted up and down. The leveling conveyor rollers 26 are rotatably connected to the adjustment plate 23. By controlling the height of the adjustment plate 23 in the support plate 21, the spacing between the upper and lower leveling conveyor rollers 26 in the leveling conveyor 2 can be changed to accommodate plates of different thicknesses.

[0041] The lower plate 33 is moved downward by the cylinder 32 to control the movement of the lower plate 33. The movement of the lower plate 33 synchronously drives the clamping plate 34 and the cutter 37 to move downward. A return spring 36 is provided between the clamping plate 34 and the lower plate 33. When the return spring 36 is not compressed, the distance between the bottom of the clamping plate 34 and the lower plate 33 is greater than the distance between the bottom of the cutter 37 and the lower plate 33. When the lower plate 33 moves downward, the clamping plate 34 first contacts the plate, and as the lower plate 33 continues to move downward, the clamping plate 34 is clamped between the clamping plate 34 and the lower cutting plate 42 under the action of the return spring 36 and the lower plate 33, and finally cut by the cutter 37. The plate is clamped before cutting by the setting of the return spring 36, so as to ensure the accuracy of cutting. At the same time, it can adapt to the cutting of plates of different thicknesses.

[0042] The cut plates are transported via a conveyor belt 44 .
