Description

Technical Field

[0001] The utility model relates to the technical field of pipeline coiling devices, and more specifically, to an automatic polyethylene coil curling machine. Background Art

[0002] Polyethylene pipe, also known as PE pipe, is a polymer material formed by the polymerization of monomer ethylene. It has a series of advantages such as impact resistance, crack resistance, aging resistance, corrosion resistance, and strong insulation. Therefore, it is widely used in water supply and drainage, gas transmission and power engineering. Common PE pipes can generally be divided into three types according to their pipeline identification lines: drainage pipes, gas pipes and mining pipes.

[0003] When operators are performing coiling operations on polyethylene pipes, they often use automatic crimping machines to coil long polyethylene pipes to facilitate pipeline transportation operations. However, in actual use, although existing automatic crimping machines have basic coiling functions, they generally cannot automatically adjust the spacing between the conveying wheels, which makes it impossible for the automatic crimping machines to coil pipes of different widths. Therefore, they need to be improved. Utility Model Content

[0029] An adjustment mechanism, the adjustment mechanism is arranged below the movable plate 3;

[0030] Among them, the adjustment mechanism includes a No. 1 motor 4, which is fixedly installed at the front end of the left side of the lower surface of the bed body 1. The other end of the output shaft of the No. 1 motor 4 is fixedly sleeved with a circular shaft 5 located below the movable plate 3. The outer surface of the circular shaft 5 is fixedly sleeved with a rotating rod 6. The other end of the rotating rod 6 is hinged with a connecting rod 7. The other end of the connecting rod 7 is hinged to the middle part of the lower surface of the movable plate 3. The rotating rod 6 rotates to make the connecting rod 7 drive the movable plate 3 to move forward and backward as a whole.

[0031] When the No. 1 motor 4 is running, the circular shaft 5 will drive the rotating rod 6 to start rotating. At this time, the connecting rod 7 will start rotating under the drive of the rotating rod 6. At the same time, the other end of the connecting rod 7 will drive the movable plate 3 as a whole, so that the movable plate 3 as a whole starts to move forward along the inner surface of the movable groove 2.

[0032] Among them, a No. 2 motor 8 is fixedly installed on the left side of the lower surface of the bed body 1 and the left side of the lower surface of the movable plate 3. The other end of the output shaft of the No. 2 motor 8 is fixedly sleeved with a driving shaft 9. There are two driving shafts 9. The top ends of the two driving shafts 9 respectively penetrate the bed body 1, the pad 24 and the movable plate 3 and extend to the top of the movable plate 3 and the pad 24 respectively. The lower surface of the bed body 1 and the lower surface of the movable plate 3 are movably connected with a connecting shaft 10 located on the right side of the driving shaft 9. There are two connecting shafts 10. The top ends of the two connecting shafts 10 respectively penetrate the bed body 1, the pad 24 and the movable plate 3 and extend to the top of the movable plate 3 and the pad 24 respectively.

[0033] When the second motor 8 is running, the drive shaft 9 will start to rotate.

[0034] The upper surfaces of the two driving shafts 9 and the connecting shaft 10 are both movably sleeved with conveying wheels 11 . There are four conveying wheels 11 , and the sizes of the four conveying wheels 11 are the same.

[0035] When the driving shaft 9 starts to rotate as a whole, the conveying wheel 11 drives the polyethylene pipe to start moving rightward.

[0036] A sliding groove 12 is provided on the right side of the upper surface of the bed body 1 , a connecting plate 13 is movably connected to the inner surface of the sliding groove 12 , and an extrusion wheel 14 is movably installed inside the connecting plate 13 .

[0037] Due to the design of the sliding groove 12 , the extrusion wheel 14 as a whole can move forward and backward along the inner surface of the sliding groove 12 .

[0038] Among them, the upper surface of the bed body 1 is fixedly connected with a fixing plate 15 located on the front side of the connecting plate 13, and the outer surface of the fixing plate 15 is fixedly installed with a pneumatic cylinder 16. The rear end of the pneumatic cylinder 16 passes through the fixing plate 15 and extends to the front surface of the connecting plate 13 and is fixedly connected thereto.

[0039] When the pneumatic cylinder 16 operates, the connecting plate 13 as a whole starts to move backward along the inner surface of the sliding groove 12 .

[0040] Among them, a mounting frame 17 is fixedly connected to the left side of the upper surface of the bed body 1, and a No. 3 motor 18 is fixedly connected to the upper surface of the mounting frame 17. A rotating shaft 19 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 18, and a gear 20 is fixedly sleeved on the outer surface of the rotating shaft 19.

[0041] When the third motor 18 is running, the shaft 19 and the gear 20 will start to rotate.

[0042] Among them, the outer surface of the gear 20 is meshed with a tooth plate 21, the bottom end of the tooth plate 21 is fixedly connected to a limit plate 22, the lower surface of the limit plate 22 and the upper surface of the conveying wheel 11 are movably connected, and the front and rear sides of the middle of the upper surface of the limit plate 22 are fixedly connected to the limit column 23, and the top end of the limit column 23 passes through the mounting frame 17 and extends to the top of the mounting frame 17.

[0043] When the gear 20 rotates, the tooth plate 21 drives the limiting plate 22 to start moving upward under the meshing transmission of the gear 20 and the limiting of the limiting column 23 .

[0044] The working principle and use process of this utility model:

[0045] First, the operator starts the No. 3 motor 18. The operation of the No. 3 motor 18 will cause the rotating shaft 19 and the gear 20 to start rotating. At this time, due to the meshing between the gear 20 and the tooth plate 21, the tooth plate 21 will start to move upward driven by the gear 20, and the limit plate 22 as a whole will follow the tooth plate 21 and move upward together under the limitation of the limit column 23, which releases the limit of the conveying wheel 11 by the limit plate 22. After replacing the conveying wheel 11 according to the actual curling needs of the pipeline, the operator starts the No. 3 motor 18 again to reset the limit plate 22 and re-limit the conveying wheel 11.

[0046] Then the operator inserts the polyethylene pipe between the four conveying wheels 11 and starts the No. 1 motor 4. As the No. 1 motor 4 runs, the round shaft 5 and the rotating rod 6 will start to rotate. At this time, the connecting rod 7 will rotate driven by the rotating rod 6. At the same time, the other end of the connecting rod 7 will drive the movable plate 3 as a whole, so that the movable plate 3 as a whole begins to move backward along the inner surface of the movable groove 2. During this process, the distance between the pad 24 and the movable plate 3 will gradually approach until the outer surface of the four conveying wheels 11 and the outer surface of the pipe are in contact. At this time, the operator starts the No. 2 motor 8 and the pneumatic cylinder 16. The operation of the No. 2 motor 8 will cause the driving shaft 9 to start rotating as a whole and cause the conveying wheel 11 to drive the pipe to move to the right, while the operation of the pneumatic cylinder 16 will cause the extrusion wheel 14 as a whole to start squeezing the pipe while moving backward, causing the pipe to curl. Finally, the curling operation of the pipe will be completed under the joint action of the conveying wheel 11 and the extrusion wheel 14.
