Description

Technical Field

[0001] This utility model belongs to the technical field of oil pipe production equipment, specifically relating to an automatic pipe winding machine. Background Technology

[0002] High-pressure hydraulic hoses are pipes used to transport high-pressure fluids, commonly found in fuel injection systems and hydraulic systems. They typically consist of an inner tube, a reinforcing layer, and an outer protective layer. The outer protective layer is usually made of rubber to ensure good weather resistance and abrasion resistance. However, in many industrial environments and mechanical installations, high-pressure hydraulic hoses are easily damaged by impacts, pressure, or scratches from external objects, affecting their service life. Therefore, to prevent scratches, wear, or dents on the outer layer, a protective sleeve is wrapped around the high-pressure hydraulic hose for protection and isolation. However, existing hose winding machines subject the hose to the winding force of the sleeve, resulting in significant swaying and making it difficult for workers to control the hose, posing a safety hazard.

[0003] Therefore, the above problems urgently need to be solved. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides an automatic pipe winding machine that reduces the swinging of the oil pipe during the winding process, improves safety, and has high winding efficiency while reducing labor costs.

[0005] Technical Solution: To achieve the above objectives, this utility model provides an automatic tube winding machine, including a machine base. A winding mechanism is connected to the top surface of the machine base. The winding mechanism includes a machine housing, with a moving plate connected to one end of the housing. A stationary tube is located at the center of the moving plate, and the stationary tube is a hollow tube. A motor is installed inside the machine housing, and the motor and the moving plate are driven together, with the moving plate rotating around the stationary tube. The moving plate has a tube inlet and a fixed tube support, with the fixed tube support positioned near the tube inlet. The machine housing has auxiliary wheels arranged around the moving plate. During operation, the worker inserts the oil pipe into the stationary tube, places the sleeve into the tube inlet, and winds one end of the sleeve around the fixed tube support, then starts the motor to drive the moving plate to rotate. As the moving plate rotates, the sleeve is wound around the oil pipe. During the winding process, the worker must hold the oil pipe tightly to prevent it from being rotated. As the worker pulls the oil pipe out of the stationary tube, the sleeve is wound around the oil pipe. This invention improves the efficiency of sleeve winding, and during the winding process, the oil pipe is in a stationary position, reducing pipe swaying, simplifying pipe control for workers, and enhancing safety. Furthermore, the rotating disc is constrained by the auxiliary wheel, ensuring smooth rotation, reducing noise from the winding machine, and improving the working environment.

[0006] Furthermore, in the aforementioned automatic tube winding machine, the tube insertion ports are arranged in an array around the center of the moving disc, and the fixed tube rack is correspondingly arranged with the tube insertion ports. By arranging the tube insertion ports around the center of the moving disc, multiple sleeves can be wound simultaneously, reducing repetitive operations and improving work efficiency.

[0007] Furthermore, in the aforementioned automatic tube winding machine, the tube insertion port is installed through the machine housing. Since the sleeve is typically long while the oil pipe is shorter, the tube insertion port allows the sleeve to be inserted from the end of the housing furthest from the moving plate, passing through the insertion port for winding. Once winding is complete, the sleeve is cut off, and then the winding operation can begin on the other oil pipe. This eliminates the need to cut the sleeve beforehand, improving sleeve feeding efficiency. Alternatively, a shorter sleeve can be inserted into the insertion port from the moving plate end for winding, reducing sleeve waste and allowing the tube winding machine to meet different sleeve feeding requirements, thus improving its adaptability.

[0008] Furthermore, in the aforementioned automatic tube winding machine, a first support portion is provided at the end of the tube inlet away from the machine housing. The first support portion extends out of the moving disc and is a semi-circular shape with its opening facing upwards. A chamfer is provided at the end of the first support portion away from the machine housing. The provision of the first support portion shortens the distance between the tube inlet and the fixed tube support, reduces the swing amplitude during tube winding, prevents the tube from being thrown out of the tube inlet, and improves safety.

[0009] Furthermore, in the aforementioned automatic tube winding machine, the fixed tube support includes a support column connected to the moving plate. A crossbar is connected to the end of the support column away from the moving plate. The end of the crossbar away from the support column extends towards the center of the tube inlet. A fixed tube rod is connected to the end of the crossbar away from the support column. The fixed tube rod and the tube inlet are coaxially arranged. During the tube winding process, one end of the tube is placed in the tube inlet, and the other end of the tube is fitted onto the outside of the fixed tube rod. Then, the worker pulls out one end of the tube and winds it around the oil pipe. During the winding process, the tube is restricted by the fixed tube rod, ensuring that the tube winds along the outer surface of the oil pipe, ensuring tight winding, and ensuring winding quality.

[0010] Furthermore, in the aforementioned automatic tube winding machine, a second support portion is provided at the end of the stationary tube furthest from the machine housing. The second support portion extends in the direction furthest from the machine housing, and a chamfer is provided at the end of the second support portion furthest from the machine housing. When the oil tube is wound to the end, the oil tube detaches from the stationary tube, and the second support portion provides support for the oil tube, reducing the swing amplitude of the oil tube, reducing the difficulty of the worker's work, and improving safety.

[0011] Furthermore, in the aforementioned automatic tube winding machine, the auxiliary wheel includes a connecting shaft connected to the machine housing. A bearing portion is connected to the outer wall of the connecting shaft, and the bearing portion abuts against the moving disc. The bearing portion is configured as a ball or needle roller bearing to ensure smooth rolling and reduce equipment noise.

[0012] Furthermore, in the aforementioned automatic pipe winding machine, the end of the machine base near the moving plate extends out of the machine housing to form a worktable. The worktable can hold oil pipes, sleeves, or tools, and can provide support for long oil pipes, improving work convenience.

[0013] Furthermore, in the aforementioned automatic tube winding machine, the stationary tube is connected to an upper stop bar, which is horizontally positioned, and the stationary tube is connected to a lower stop bar, which is located below the upper stop bar. The upper and lower stop bars restrict the movement of the oil tube, preventing it from swinging during winding and improving safety.

[0014] Furthermore, in the aforementioned automatic tube winding machine, there are two or more lower stop bars, with the two lower stop bars arranged in a V-shape below the upper stop bar. The V-shaped arrangement of the lower stop bars reduces the space for the oil tube to swing, thereby improving the stability of the oil tube during the winding process.

[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects: The automatic pipe winding machine of this utility model reduces pipe swaying, lowers the difficulty for workers to control the pipe, and improves safety. The auxiliary wheel constrains the rotation of the moving disc, making its rotation smooth, reducing the working noise of the pipe winding machine, and improving the working environment. The first support unit shortens the distance between the pipe inlet and the fixed pipe support, reducing the swaying amplitude during pipe winding, preventing the pipe from being thrown out of the inlet, and improving safety. The second support unit, upper stop, and lower stop reduce the pipe swaying space, improving the stability of the pipe during the winding process and enhancing safety. Attached Figure Description

Detailed Implementation

[0019] Example 1

[0020] like Figure 1An automatic tube winding machine is shown, comprising a machine base 1, with a winding mechanism connected to the top surface of the machine base 1. The winding mechanism includes a housing 24, with a movable disc 21 connected to one end of the housing 24. A stationary tube 22 is located at the center of the movable disc 21, and the stationary tube 22 is a hollow tube. A motor is installed inside the housing 24, and the motor is connected to the movable disc 21 for driving. The movable disc 21 rotates around the stationary tube 22. The movable disc 21 has a tube inlet 211 and a tube support 212, with the tube support 212 positioned adjacent to the tube inlet 211. The housing 24 has auxiliary wheels 23 arranged around the movable disc 21. The tube inlets 211 are arranged in an array around the center of the movable disc 21, and the tube supports 212 are correspondingly arranged with the tube inlets 211. The tube inlets 211 penetrate the housing 24.

[0021] like Figure 2 The automatic tube winding machine shown has a first support portion 213 at the end of the tube inlet 211 away from the machine housing 24. The first support portion 213 extends out of the moving plate 21 and is a semi-circular shape with an upward opening. The end of the first support portion 213 away from the machine housing 24 has a chamfer. The fixed tube frame 212 includes a support column 2122 connected to the moving plate 21. A crossbar 2123 is connected to the end of the support column 2122 away from the moving plate 21. The end of the crossbar 2123 away from the support column 2122 extends towards the center of the tube inlet 211. A fixed tube rod 2124 is connected to the end of the crossbar 2123 away from the support column 2122. The fixed tube rod 2124 and the tube inlet 211 are coaxially arranged. The stationary tube 22 has a second support portion 221 at the end away from the machine housing 24. The second support portion 221 extends away from the machine housing 24 and has a chamfer at the end of the second support portion 221 away from the machine housing 24. The auxiliary wheel 23 includes a connecting shaft 231 connected to the housing 24. A bearing portion 232 is connected to the outer wall of the connecting shaft 231, and the bearing portion 232 abuts against the moving plate 21. The bearing portion 232 is a ball bearing or a needle bearing. The end of the machine base 1 near the moving plate 21 extends out of the housing 24 to form a worktable 11. The stationary tube 22 is connected to an upper stop rod 223, which is horizontally arranged. The stationary tube 22 is also connected to a lower stop rod 222, which is located below the upper stop rod 223. There are two or more lower stop rods 222, which are arranged in a V-shape below the upper stop rod 223.

[0022] During the casing winding process, the worker needs to insert the oil pipe into the stationary pipe 22, place the casing into the insertion port 211, and slip one end of the casing onto the stationary pipe rod 2124. The casing then wraps around the pipe rod 2124, and the worker winds one end of the casing around the oil pipe. The motor is then started, driving the rotating disc 21 to rotate. As the rotating disc 21 rotates, the casing is wound around the oil pipe. During the winding process, the worker needs to grip the oil pipe tightly and pull it out of the stationary pipe 22. Once the oil pipe is completely pulled out of the stationary pipe 22, the casing winding is complete. The motor is then turned off.
