[0002] Existing dual-station plastic pipe winding machines typically consist of two independently operating winding devices, A and B, which are fixed at different stations. After winding is completed at station A, the pipe needs to be manually cut and re-threaded to station B. This requires frequent manual operation, and each switch requires manual alignment of the winding device with the pipe traction path, resulting in low work efficiency. Utility Model Content

[0003] This invention addresses the aforementioned problems in the existing technology by proposing a dual-station winding machine capable of automatically switching between two workstations.

[0004] This utility model can be achieved through the following technical solutions:

[0009] Two winding devices are respectively installed at both ends of the rotating arm. The two winding devices are switched between the winding station and the waiting station by rotating the rotating arm.

[0010] The positioning mechanism includes a positioning pin that can extend and retract along the axial direction and a positioning sleeve correspondingly disposed on the rotating arm. The positioning pin extends out and is embedded in the positioning sleeve to lock the position of the rotating arm and the winding device.

[0011] As a further improvement of this utility model, the rotating arm has a rotating shaft at its middle position, and the driving mechanism is connected to the rotating shaft through a transmission assembly.

[0012] As a further improvement of this utility model, the drive mechanism consists of a first servo motor and a first reducer, and the transmission component consists of a meshing drive gear and a driven gear. The drive gear is connected to the output end of the first reducer and is mounted on the rotating shaft.

[0013] As a further improvement of this utility model, the diameter of the driving gear is smaller than the diameter of the driven gear.

[0014] As a further improvement of this utility model, the winding device includes a second servo motor, a second reducer, a rotating shaft, and a winding reel connected in sequence, wherein the second servo motor drives the winding reel to rotate through the rotating shaft.

[0015] As a further improvement of this utility model, the second servo motor, the second reducer and the winding reel are respectively located on the front and rear sides of the rotating arm, and the rotating shaft passes through the rotating arm.

[0016] As a further improvement of this utility model, it also includes a positioning plate, one end of which is fixedly mounted on the rotating arm, and the other end of which extends close to the positioning pin. The positioning sleeve is mounted on the end face of the positioning plate facing the positioning pin.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Improve work efficiency: The dual-station design combined with an automated rotating arm and positioning mechanism allows a single machine to seamlessly switch between different stations, reducing the need for manual intervention, greatly shortening non-productive time, and significantly improving production efficiency and ease of operation.

[0022] 2. Precise positioning: By using the combination of positioning pins and positioning sleeves, the winding device is ensured to be precisely aligned after each switch, avoiding errors caused by manual adjustment and improving the consistency of product quality.

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0034] like Figures 1-5 As shown, this utility model provides a dual-station winding machine, comprising:

[0035] The frame 100 has a winding station 110 and a waiting station 120 distributed on the left and right sides. The equipment can perform the winding of pipes at one station while the other station can prepare for the next round of winding operation.

[0036] A drive mechanism, which is mounted on the frame 100 and is used to provide power;

[0037] The rotating arm 130 is connected at one end to the output end of the drive mechanism and rotates through the power of the drive mechanism. The design of the rotating arm 130 allows the two winding devices 140 to automatically switch between the winding station 110 and the waiting station 120 without manual intervention, which greatly improves the degree of automation.

[0038] Two winding devices 140 are respectively installed at both ends of the rotating arm 130. The rotating arm 130 is driven to rotate by the drive mechanism to realize the switching of the two winding devices 140 between the winding station 110 and the waiting station 120.

[0039] The positioning mechanism 150 includes a positioning pin 151 that can extend and retract along the axial direction and a positioning sleeve 152 correspondingly disposed on the rotating arm 130. The positioning pin 151 extends out and is embedded in the positioning sleeve 152 to lock the position of the rotating arm 130 and the winding device 140, ensuring that the winding device 140 can be accurately aligned. When switching is required, the positioning pin 151 disengages from the positioning sleeve 152 and moves outward, allowing the rotating arm 130 to rotate.

[0040] It should be noted that in the existing dual-station winding machine, the two winding devices 140 are fixedly installed on two stations respectively. After the winding is completed at station A, the tube needs to be cut manually and re-threaded to station B. This requires frequent manual operation, resulting in low work efficiency.

[0041] In contrast, the dual-station winding machine provided in this embodiment can smoothly switch between the two winding devices 140 and the waiting station 120 without manual operation, and is equipped with a positioning mechanism 150 to achieve precise positioning of the winding device 140. This design has at least the following advantages:

[0042] 1. Improve work efficiency: The dual-station design combined with the automated rotating arm 130 and positioning mechanism 150 allows a single machine to seamlessly switch between different stations, reducing the need for manual intervention, greatly shortening non-productive time, and significantly improving production efficiency and ease of operation.

[0043] 2. Precise positioning: By using the positioning pin 151 and positioning sleeve 152, the winding device 140 can be precisely aligned after each switch, avoiding errors caused by manual adjustment and improving the consistency of product quality.

[0044] 3. Enhanced operational safety and stability: By reducing the number of manual operation steps, not only is labor intensity reduced, but potential safety hazards during operation are also reduced. At the same time, the stable mechanical structure and control system also enhance the stability of equipment operation.

[0045] Preferably, the rotating arm 130 has a rotating shaft 131 at its middle position, and the drive mechanism is connected to the rotating shaft 131 via a transmission assembly.

[0046] The drive mechanism consists of a first servo motor 132 and a first reducer 133. The transmission component consists of a meshing drive gear 134 and a driven gear 135. The drive gear 134 is connected to the output end of the first reducer 133 and is mounted on the rotating shaft 131.

[0047] The first servo motor 132 provides precise speed and position control, which is crucial for achieving automated operation. The first reducer 133 is used to adjust the output torque and speed, making the drive system more adaptable to actual working needs. The gear transmission method ensures the efficiency and stability of power transmission.

[0048] In particular, since the diameter of the driving gear 134 is smaller than that of the driven gear 135, this design can effectively reduce the rotational speed while increasing the torque, making it suitable for applications that require a larger torque to drive the swing arm 130.

[0049] Preferably, the winding device 140 includes a second servo motor 141, a second reducer 142, a rotating shaft 143, and a winding reel 144 connected in sequence. The second servo motor 141 drives the winding reel 144 to rotate through the rotating shaft 143. The second servo motor 141, the second reducer 142, and the winding reel 144 are located on the front and rear sides of the rotating arm 130, respectively, and the rotating shaft 143 passes through the rotating arm 130.

[0050] This layout not only makes efficient use of space, but also helps to balance the weight distribution on both sides of the swing arm 130, reducing mechanical stress caused by imbalance, thereby improving the overall stability and service life of the equipment.

[0051] Preferably, it also includes a positioning plate 153, one end of which is fixedly mounted on the rotating arm 130, and the other end of which extends close to the positioning pin 151. A positioning sleeve 152 is disposed on the end face of the positioning plate 153 facing the positioning pin 151, thereby allowing the positioning pin 151 to smoothly insert into or remove from the positioning sleeve 152, achieving precise positioning, locking, and unlocking of the winding device 140. Specifically:

[0052] The positioning mechanism 150 also includes a positioning cylinder 154. The positioning pin 151 is mounted on the piston rod of the positioning cylinder 154. The positioning pin 151 is driven by the positioning cylinder 154 to move back and forth along its axis, so as to achieve the purpose of inserting or removing the positioning pin 151 from the positioning sleeve 152.

[0053] Furthermore, in order to improve the reliability and automation of operation, a sensor switch (not shown in the figure) is provided on the positioning cylinder 154. The sensor switch is electrically connected to the control system and configured to detect the extension or retraction state of the positioning pin 151, so that the control system can monitor and control the position of the positioning pin 151 in real time.

[0054] Specifically, after the positioning pin 151 is inserted into the positioning sleeve 152, the control system controls the winding device 140 to perform winding work. After the positioning pin 151 is removed from the positioning sleeve 152, the control system controls the rotating arm 130 to rotate so as to realize the switching of the two winding devices 140 between different work positions.

[0055] In other words, by driving the positioning pin 151 and the positioning sleeve 152 with the positioning cylinder 154, the winding device 140 achieves high-precision alignment after each station switch, which significantly improves the consistency of finished product quality. At the same time, the automated positioning mechanism reduces manual intervention, which not only improves work efficiency but also reduces the risk of human error.

[0056] Preferably, the side of the frame 100 closest to the winding station 110 is the feed end, and the height of the winding station 110 is higher than the height of the waiting station 120. In this case, the winding station 110 is at least higher than the feed end of the frame 100 to tension the tube. This height difference design ensures that the tube maintains appropriate tension when entering the winding station 110, which is crucial for ensuring winding quality. Properly tensioned tubes can avoid problems such as looseness, slippage, or irregular winding, thereby improving the regularity and tightness of the finished product.
