[0003] Before use, PVC profiles need to be cut by cutting equipment to achieve a suitable size for use. In the prior art, most cutting devices cannot cut PVC profiles to a fixed length when in use, which reduces the accuracy of cutting and causes a certain deviation between the cut PVC profiles and the predetermined length, making it impossible to use the cut PVC profiles normally, resulting in a waste of materials and insufficient practicality. Therefore, it is necessary to redesign the PVC profile fixed-length cutting device to address the above problems. Utility Model Content

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 1-6 The PVC profile fixed-length cutting device comprises a processing table 1, a screw rod 2 is rotatably installed on the upper end surface of the processing table 1 through a moving groove, a motor 3 connected to the screw rod 2 is fixedly installed on the outer wall of the processing table 1, and a moving block 5 is threadedly installed on the outer wall of the screw 2 through a limiting mechanism. The limiting mechanism comprises a limiting rod 4 fixedly installed inside the moving groove, and the limiting rod 4 slides through the moving block 5. The limiting rod 4 can limit the moving block 5 so that the moving block 5 can only move axially along the outer wall of the screw 2. A clamping frame 6 is fixedly installed at the end of the moving block 5, and the inner walls on both sides of the clamping frame 6 are fixedly connected with a clamping plate 8 through a telescopic mechanism. The telescopic mechanism comprises an electric push rod 7 fixedly installed on the inner wall of the clamping frame 6, and the telescopic end of the electric push rod 7 is fixedly connected to the outer wall of the clamping plate 8.
[0024] The inner walls of the two clamping plates 8 are fixedly installed with anti-skid pads 9, which are made of rubber material. The rubber material has good elasticity and softness, which enables it to form a closer contact between the surface and the object, thereby increasing friction and improving the friction coefficient. A scale rod 11 is fixedly installed on the upper end surface of the processing table 1 through a moving frame 10, and an extrusion plate 13 is slidably installed on the outer wall of the scale rod 11 through a stabilizing mechanism. The stabilizing mechanism includes a stabilizing rod 12 fixedly installed inside the moving frame 10, and the stabilizing rod 12 slides through the extrusion plate 13. The stabilizing rod 12 can limit the extrusion plate 13, so that the extrusion plate 13 can only move axially along the outer wall of the scale rod 11.
[0025] A reset spring 14 is installed on the outer wall of the scale rod 11, and both ends of the reset spring 14 are elastically connected to the inner wall of the moving frame 10 and the outer wall of the extrusion plate 13 respectively. A support frame 15 is fixedly installed on the upper end surface of the processing table 1, and a cutting device 17 is fixedly connected to the bottom wall of the support frame 15 through a lifting mechanism. The lifting mechanism includes a cylinder 16 fixedly installed on the bottom wall of the support frame 15, and the telescopic end of the cylinder 16 is fixedly connected to the upper end surface of the cutting device 17. The blade of the cutting device 17 and the inner wall of the extrusion plate 13 are aligned with the zero scale of the scale rod 11. A collecting groove is provided on the outer wall of the processing table 1, and a cutting opening connected to the collecting groove is provided on the upper end surface of the processing table 1, and a collecting box 18 is slidably installed inside the collecting groove.
[0026] When the utility model is used, the profile is placed in the clamping frame 6 and between the two clamping plates 8. Then the profile can be pushed to align its end with the inner wall of the extrusion plate 13. Then the two electric push rods 7 can respectively drive the clamping plates 8 on the same side to move, so that the two clamping plates 8 are close to each other and the profile is clamped and fixed by the anti-skid pad 9. The anti-skid pad 9 can increase the friction with the surface of the profile and improve the firmness of the clamping. Under the telescopic action of the electric push rod 7, the two clamping plates 8 can clamp and fix profiles of different sizes.
[0027] When the profile is cut to a fixed length, the motor 3 can drive the screw 2 to rotate, and the screw 2 drives the moving block 5 to move by cooperating with the limit rod 4, so that the moving block 5 can drive the clamping frame 6, thereby driving the clamped and fixed profile to move. The profile can squeeze the extrusion plate 13 when it moves. As the profile continues to move, the extrusion plate 13 is subjected to force and can slide on the outer wall of the scale rod 11 through the cooperation of the stabilizing rod 12, and squeeze the reset spring 14. The elasticity of the reset spring 14 can tension the extrusion plate 13 to prevent it from automatically sliding on the outer wall of the scale rod 11. At this time, when the extrusion plate 13 is aligned with the outer wall scale of the scale rod 11 after movement, it is the cutting length of the profile. Then the cylinder 16 can drive the cutting device 17 to descend to cut the profile to a fixed length. The powder and debris generated during cutting can fall into the collection trough through the cutting opening and be collected by the collection box 18. The powder and debris inside the collection box 18 can be cleaned by pulling it out of the collection trough.
[0028] 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.
