Description

Technical Field

[0001] This utility model relates to the field of pipe manufacturing technology, and in particular to an automatic pipe winding device. Background Technology

[0002] In the pipe manufacturing process, pipes are usually rolled into coils for convenient storage and transportation, which requires a winding device. Existing winding devices include a winding drum and a guide rod. When using an existing winding device, one end of the pipe is fixed to the winding drum. As the winding drum rotates and the guide rod guides the pipe, the pipe is wound layer by layer onto the winding drum. During the winding process, in order to maintain a certain distance between the free end of the guide rod and the outer layer of pipe, the pipe guide rod will rotate at a certain angle as the number of pipe layers wound on the winding drum increases. This causes changes in the tension of the pipe, resulting in inconsistent tightness of the wound pipe and uneven winding.

[0003] Therefore, there is a need for an automatic pipe winding device to solve the above problems. Utility Model Content

[0004] This utility model proposes an automatic pipe winding device, which buffers the tension of the pipe during the winding process through the cooperation of angle sensing and swing arm, so that the tightness of the pipe after winding is consistent and the pipe is wound evenly.

[0005] The technical solution of this utility model is implemented as follows:

[0006] An automatic pipe winding device includes a frame, characterized in that a horizontally arranged winding drum is rotatably mounted on the frame, a sliding frame is slidably mounted on the frame along the axial direction of the winding drum, the sliding frame is located upstream of the winding drum along the pipe's forward direction, a horizontally arranged rotating shaft is rotatably mounted on the sliding frame, one end of the rotating shaft near the frame passes through the sliding frame and is connected to an angle sensor, a first guide rod and a second guide rod are fixedly mounted on the other end of the rotating shaft, a plurality of guide wheels are rotatably mounted on the second guide rod, a damping wheel is mounted on the second guide rod via an adjusting arm assembly, the damping wheel is connected to a counter, a connecting plate is fixedly mounted on the rotating shaft, a tension spring is provided between the connecting plate and the sliding frame for causing the free end of the first guide rod to abut against the winding drum, a swing arm is rotatably mounted on the frame, the swing arm is located upstream of the second guide rod, and a horizontally arranged tension adjusting roller is rotatably mounted on the swing arm.

[0007] As a preferred technical solution, two horizontally arranged guide columns are fixedly installed on the frame, and a sliding plate is slidably installed on both guide columns. The sliding plate is fixedly connected to the sliding frame through a connecting column. A horizontally arranged lead screw is rotatably installed on the frame, and a nut is threaded onto the lead screw. The nut is fixedly installed on the sliding plate. The lead screw, the two guide columns, and the connecting column are all arranged parallel to the winding drum.

[0008] As a preferred technical solution, the second guide rod is provided with a through groove, and the adjusting arm assembly includes a first adjusting arm and a second adjusting arm. The first adjusting arm and the second adjusting arm are installed together by a first bolt, and the free end of the first adjusting arm is connected to the second guide rod by a second bolt. The second bolt is located in the through groove, and the damping wheel is rotatably installed on the free end of the second adjusting arm.

[0009] As a preferred technical solution, two vertically arranged limiting plates are fixedly installed on the top of the free end of the first guide rod, and a first guide roller is rotatably installed between the two limiting plates.

[0010] As a preferred technical solution, a mounting plate is fixedly installed at the end of the rotating shaft away from the frame, and both the first guide rod and the second guide rod are fixedly installed on the mounting plate.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0012] Since the automatic pipe winding device includes a sliding frame, during the pipe winding process, the free end of the pipe is fixedly installed on the winding drum, the bottom of the pipe rests on the guide wheels, and the damping wheel presses the pipe against two adjacent guide wheels as it rotates around the drum. At the same time, the sliding frame slides along the axis of the winding drum. Under the guidance of the first and second guide rods, the pipe is wound layer by layer onto the winding drum. During this process, under the action of the tension spring, the free end of the first guide rod abuts against the winding drum or the outer layer of pipe. As the number of pipe layers on the winding drum increases, the angle of the first guide rod also changes, that is, the rotating shaft will rotate a certain angle. The angle sensor senses the rotation angle of the rotating shaft, and the swing arm swings according to the rotation angle of the rotating shaft, thereby adjusting the tension of the pipe and ensuring that the tightness of the pipe remains consistent after winding, thus achieving uniform pipe winding.

[0013] Since the automatic pipe winding device includes a lead screw, during the pipe winding process, the lead screw rotates, and with the cooperation of the guide rod and nut, the sliding plate moves horizontally along the axis of the lead screw. Since the sliding plate is connected to the sliding frame through the connecting column, and the lead screw is set parallel to the winding drum, the rotation of the lead screw realizes the reciprocating movement of the sliding frame along the axis of the winding drum. As the winding drum rotates, the pipe is wound layer by layer on the winding drum.

[0014] Since the adjusting arm assembly includes a first adjusting arm and a second adjusting arm, before the pipe is wound, the first bolt and the second bolt are unlocked. By adjusting the position of the second bolt in the through groove and the angle between the first adjusting arm and the second adjusting arm, the pipe is pressed against the two guide wheels and the damping wheel. Then, the first bolt and the second bolt are locked. As the pipe advances, the friction between the pipe and the damping wheel drives the damping wheel to rotate. The counter can measure the length of the wound pipe. Compared with the existing winding device that uses one mounting arm, one damping wheel and one guide wheel, in this utility model, the damping wheel is installed on the second guide rod through the cooperation of the first adjusting arm, the second adjusting arm, the first bolt, the second bolt and the through groove. This allows the damping wheel to cooperate with the two guide wheels and the counter, increasing the adjustment range of the damping wheel. The damping wheel can press pipes of different sizes against the two guide wheels. Furthermore, the cooperation between the damping wheel and the two guide wheels increases the contact area between the damping wheel and the pipe, thereby increasing the friction between the damping wheel and the pipe and making the measurement of the pipe length more accurate.

[0026] Furthermore, a through groove 21 is provided on the second guide rod 8, and the adjusting arm assembly includes a first adjusting arm 22 and a second adjusting arm 23. The first adjusting arm 22 and the second adjusting arm 23 are installed together by a first bolt 24.

[0027] Furthermore, two vertically arranged limiting plates 26 are fixedly installed on the top of the free end of the first guide rod 7, and a first guide roller 27 is rotatably installed between the two limiting plates 26.

[0028] Secondly, a mounting plate 28 is fixedly installed on the end of the rotating shaft 5 away from the frame 1, and the first guide rod 7 and the second guide rod 8 are both fixedly installed on the mounting plate 28.
