[0002] Aluminum-plastic pipe is a new type of pipe made of a longitudinally welded aluminum tube, inner and outer polyethylene plastic layers, and hot-melt adhesive between the layers, co-extruded and laminated. Aluminum-plastic pipe (aluminum-plastic composite pipe) is a popular pipe material on the market. Due to its light weight, durability, and easy installation, and its flexibility, it is particularly suitable for use in home decoration.

[0003] During the processing, it is necessary to cut the continuously processed aluminum-plastic pipe into the required length. However, the existing cutting device cuts the aluminum-plastic pipe into equal-length pipes and directly drops them into the receiving trolley. The height difference between the bottom plate of the receiving trolley and the trough body for conveying after cutting is large. The cut pipe falls directly into the receiving trolley, which is easy to be broken, thereby affecting the quality of the outer surface. Utility model content:

[0032] The lower portion of the lower material guide chute 13 extends out of the bottom end of the through slot on the right side of the top plate of the frame 10;

[0033] A material receiving rack 30 is provided at the lower right part of the top plate of the frame 10, and a material receiving box 40 is placed on the material receiving rack 30. A material receiving lifting plate 31 is installed on the material receiving rack 30, and the material receiving lifting plate 31 is inserted into the middle through groove 410 of the bottom plate of the material receiving box 40. The bottom end of the lower material guide chute 13 faces the material receiving box 40 and is close to the top of the material receiving box 40.

[0037] Furthermore, the bottom end of the vertical screw 37 is screwed to a limit nut 371. By rotating the limit nut 371, the height of the vertical screw 37 can be adjusted to limit the lifting height of the material receiving lifting plate 31.

[0038] Furthermore, guide rails 39 extending left and right are fixed on the ground in front and rear of the rack 35 , and the lower part of the wheel 32 is inserted into the guide groove formed in the middle of the top surface of the corresponding guide rail 39 .

[0039] Furthermore, raised limit strips 301 are fixed on the left, right, front and rear of the top surface of the top plate of the material receiving frame 30, and the four raised limit strips 301 form a rectangular raised frame. Bent support feet 41 are fixed at the four corners of the bottom surface of the bottom plate of the material receiving box 40, and the four feet of the rectangular raised frame are inserted into the corresponding bent support feet 41.

[0040] This structure allows the material receiving box 40 to be placed on the top surface of the top plate of the material receiving frame 30, with accurate positioning and not easy to move.

[0041] Furthermore, the top surface of the receiving and lifting plate 31 is formed by two adjacent oblique walls, one on each side of which is close to the other and extends obliquely upward. This structure allows tubes that fall onto the top surface of the receiving and lifting plate 31 to roll forward or backward along the top surface, ensuring that the tubes are well placed in the receiving box 40 and are not easily stuck.

[0042] Furthermore, there is a distance between the left and right sides of the middle through groove 410 and the inner side walls of the left and right side plates of the material receiving box 40, and the distance between the left and right side walls of the middle through groove 410 is less than the length of the cut aluminum-plastic tube;

[0043] The distance between the inner side walls of the front and rear side plates of the middle through groove 410 and the front side wall or the rear side wall of the middle through groove 410 is smaller than the outer diameter of the aluminum-plastic tube to be cut.

[0044] When the present embodiment is in use, the aluminum-plastic tube body after extrusion processing is conveyed to the conveying trough of the conveying guide trough body 11, and then conveyed to the right along the conveying trough. After its right end passes through the inner guide sleeve 24 and the guide sleeve 23 on the left, it enters the guide sleeve 23 and the inner guide sleeve 24 on the right, and is output along the conveying trough of the receiving and guiding trough body 12. After its conveyed length reaches the required length (this length is obtained by the meter meter on the front conveying equipment. When the meter meter obtains that its conveyed length reaches the length required to be cut, it transmits the induction signal to the control host), at this time, the tube body of the corresponding length just passes through the guide sleeve 23 on the right, and the cutting motor 281 is always in operation, so that the cutting wheel 282 keeps rotating, and the control host moves the motor 27 to operate, so that the cutting wheel 282 moves along the cutting groove 25 It moves back and forth so that when it passes between the two guide sleeves 23, the pipe body there is cut. In this process, since the transportation of the pipe body is relatively slow and the cutting wheel 582 moves quickly, there is no need to stop the machine, and the cutting can be completed during the transportation process (wherein, proximity switches are fixed on the inner side walls of the two vertical plates, which correspond to the front and rear end surfaces of the connecting plate. When the moving motor 27 is running and drives the connecting plate to move forward or backward, when its forward movement is sensed by the proximity switch at the front, it means that the cutting is completed. At this time, the control host controls the moving motor 27 to stop running. Then, when cutting is needed later, the rotating shaft of the moving motor 27 is controlled to run in the reverse direction, so that the connecting plate moves backward and is sensed by the proximity switch at the rear, indicating that the cutting is completed. The cutting is carried out in this way).

[0045] After the cutting is completed, the cutting wheel 582 is also moved out from between the two guide sleeves 23, and the subsequent tube body continues to be transported to the right guide sleeve 23, pushing the cut tube body to the right, until the tube body arrives and continues to be transported to the right along with the subsequent tube body produced, until it is above the falling groove 121 and falls from the falling groove 121, and falls into the material receiving box 40 along the middle groove of the lower guide trough body 13 (the length of the tube body is less than the distance between the left and right ends of the falling groove 121 and the middle groove of the guide trough body 13). At this time, the height adjustment of the material receiving lifting plate 31 can be achieved by operating the lifting servo motor 381. It lifts the material receiving lifting plate 31 close to the top of the material receiving box 40, and the fallen tubes will fall onto the top surface of the material receiving lifting plate 31, and roll forward or backward with its inclined surface to one side. Generally, the material receiving lifting plate 31 is lifted for a certain time (generally, it can be adjusted according to the actual production situation, such as cutting 10 tubes in 3 minutes, which will cover the entire top surface of the material receiving lifting plate 31. At this time, the lifting servo motor 381 is running, and the material receiving lifting plate 31 can be lowered to the height of the diameter of the tube. The lifting servo motor 381 can be controlled by the control host to run once every 3 minutes, so that the material receiving lifting plate 31 can be lowered by the distance of the diameter of the tube).

[0046] After the processing is completed, the lifting servo motor 381 is operated to make the material receiving lifting plate 31 move out of the middle through slot 410 of the bottom plate of the material receiving box 40, and then, the driving motor 33 is operated to move the material receiving frame 30 to the right and move it out from under the top plate of the frame 10. Then, the material receiving box 10 can be unloaded by a crane or other equipment, and then a new material receiving box 10 is installed and then the driving motor 33 is operated to move it to its original position for subsequent material receiving (its driving motor 33 is also a servo motor, and the driving motor 33 can be controlled by the control host to control the running time of the driving motor 33 to obtain its moving distance, ensuring that the distance of moving out and returning is basically the same. It can also fix a proximity switch on the top surface of the middle and right part of one of the guide rails, and a sensing block is fixed on the bottom surface of the support seat of one of the corresponding wheels. The bottom end of the sensing block is close to the fixed top of the corresponding proximity switch to understand the position to which the material receiving frame 30 is moved, which is convenient for precise control).
