In addition, similar cutting devices do not have the function of controlling the cutting length of the plate, resulting in different cutting lengths of the plate and low precision and quality of plate cutting.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-6A clamping device for PET cutting comprises a base 1, one end of the top of the base 1 is rotatably connected to a conveyor belt 2, and the bottom of the base 1 is located at both sides of the conveyor belt 2 and is provided with clamping components 3, the clamping components 3 are used to clamp the PET sheet, the top of the base 1 is located at one end of the conveyor belt 2 and is fixedly installed with a support frame 4 and a cutting frame 5 in sequence, the top of the base 1 is located at the other end of the cutting frame 5 and is provided with a limit component 6, the limit component 6 is used to control the cutting length of the PET sheet, the top of the base 1 is rotatably connected to a pair of electric rollers, and the outer sleeve of the electric roller is provided with the conveyor belt 2.

[0024] Among them, the base 1 is located between the cutting frame 5 and the limiting assembly 6 and is fixedly installed with a guide plate 7. A clamping roller 41 is rotatably connected in the support frame 4. The outer periphery of the clamping roller 41 is provided with a foam ring. The elastic effect of the foam ring facilitates the passage of plates of different thicknesses, and the clamping roller 41 can flatten the deformed or bent plates, further ensuring the accuracy of plate cutting.

[0025] In detail, a material box is placed at the bottom of the box body 1, and when the plate is cut, it will fall into the material box along the guide plate 7.

[0026] A knife groove 8 is formed on the top of the base 1, and the cutting frame 5 includes a pair of guide rods 51, which are slidably connected to the top of the base 1 and are located on both sides of the knife groove 8. A cross plate 52 is fixedly installed on the top of the guide rod 51, and a spring 53 is provided on the outer periphery of the guide rod 51. The two ends of the spring 53 are respectively fixedly connected to the bottom of the cross plate 52 and the top of the base 1. A blade 54 is fixedly installed on the bottom of the cross plate 52. The knife groove 8 is used to accommodate the blade 54 to ensure that the blade 54 can cut the plate, and the spring 53 can enable the cross plate 52 to drive the blade 54 back to its original position.

[0027] Specifically, the clamping assembly 3 includes a mounting frame 31 , which is fixedly mounted on the bottom of the base 1 , and a motor 32 is fixedly mounted on the bottom of the mounting frame 31 . A gear 33 is fixedly mounted on the shaft end of the motor 32 passing through the mounting frame 31 .

[0028] Furthermore, the inner bottom surface of the mounting frame 31 is slidably connected to two racks 35 through a pair of guide blocks 34. The two racks 35 are respectively meshed and rotated with the two sides of the gear 33. The ends of the racks 35 are fixedly installed with clamping blocks 36. When the gear 33 drives the two racks 35 to move, the movement directions of the two racks 35 are opposite, thereby achieving the function of controlling the pair of clamping blocks 36 to open and close and clamp. The facing surfaces of the pair of clamping blocks 36 are rotatably connected to a plurality of rollers. When the pair of clamping blocks 36 clamp the plate, the plate is fixed in position but can still be pushed by the conveyor belt 2.

[0029] In general, the limiting assembly 6 includes a cylinder 61, which is fixedly mounted on the top of the mounting frame 31. The axial end of the cylinder 61 passes through the mounting frame 31 and is fixedly mounted with a pressure plate 62. The top of the base 1 is located at the other end of the guide plate 7 and is fixedly mounted with a bracket 63. The stroke of the cylinder 61 is limited. Under normal circumstances, the cylinder 61 drives the pressure plate 62 to not squeeze the cross plate 52.

[0030] Finally, a first guide groove 631 and a second guide groove 632 are formed on the top of the bracket 63, and a sliding rod 64 and a sliding block 65 are slidably connected in the first guide groove 631 and the second guide groove 632 respectively, and a connecting rod 66 is rotatably connected between the sliding rod 64 and the sliding block 65, and one end of the sliding rod 64 is slidably connected to a straight plate 641, and a plurality of grooves 67 are formed at both ends of the first guide groove 631 and the second guide groove 632, and a plurality of elastic protrusions 68 are provided at both ends of the sliding rod 64 and the sliding block 65, and the grooves 67 can be clamped with the elastic protrusions 68, so that the sliding rod 64 and the sliding block 65 can achieve a self-locking effect in the first guide groove 631 and the second guide groove 632, and an inclined surface is provided at one end of the straight plate 641 close to the horizontal plate 52, so as to facilitate contact with the horizontal plate 52.

[0031] To put it in more detail, by changing the distance between the sliding rod 64 and the sliding block 65 and the cutting frame 5, the cutting length of the plate can be changed. When the sliding rod 64 moves to the top of the cross plate 52, the straight plate 641 will make up for the non-contact distance between the pressure plate 62 and the cross plate 52, and then the cylinder 61 can squeeze the cross plate 52 to cut the plate, and the end face of the sliding block 65 is connected to the connecting rod 66 through a round rod, and the inner bottom surface of the sliding block 65 is provided with a torsion spring, and the two ends of the torsion spring are respectively fixedly connected to the inner bottom surface of the sliding block 65 and the end face of the round rod, so that the connecting rod 66 can be twisted back to its original position.

[0032] Working method: When working, the PET sheet is placed on the conveyor belt 2, and the conveyor belt 2 transports the sheet through the clamping roller 41. The clamping roller 41 flattens the deformed or bent sheet, and then the motor 32 drives a pair of racks 35 to drive a pair of clamps 36 to clamp the sheet and fix its position. Because the end surface of the clamp 36 rotates with a roller, the sheet can be continued to be pushed by the conveyor belt 2, and the sheet then hits the bottom of the pushing connecting rod 66, and the top of the connecting rod 66 will push the sliding rod 64 to move forward to the top of the cross plate 52, and then the cylinder 61 drives the pressing plate 62 to press the straight plate 641 so that the sheet can be cut by the blade 54, and then the sheet falls into the material box along the guide plate 7. In addition, by sliding the sliding rod 64 and the sliding block 65 to change the distance between the two and the cutting frame 5, the cutting length of the sheet can be changed, because the elastic protrusion 68 is clamped in the groove 67, the sliding rod 64 and the sliding block 65 will not move freely.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
