Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, and in particular to a feeding mechanism for a pipe winding machine. Background Technology

[0002] Traditional pipe winding machines use a turntable to wind pipes. A motor drives the turntable to rotate, and the pipe is wound up as the turntable rotates. The pipe is also conveyed by the rotation of the turntable. When the turntable rotates, it generates tension on the pipe, which pulls the pipe towards the turntable. However, the turntable pulling the pipe can easily cause deformation. In addition, a high-power motor is needed to drive the turntable to ensure that the pipe can be conveyed smoothly, but high-power motors are expensive, which in turn increases the cost of the equipment.

[0003] Therefore, further improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding mechanism for a pipe winding machine that is simple in structure, has high conveying efficiency, good product quality, low cost, and strong practicality, so as to overcome the shortcomings of the prior art.

[0005] A feeding mechanism for a pipe winding machine designed for this purpose is characterized by comprising a traction device, a guiding device, and a guide tube device for rotating the pipe vertically. The traction device includes an upper conveying component and a lower conveying component, which form a conveying interval for conveying the pipe. The upper conveying component is vertically movable above the lower conveying component. When the upper conveying component moves downward, it presses the pipe onto the conveying interval, and the lower conveying component drives the pipe forward so that the pipe passes through the guiding device and the guide tube device in sequence before reaching the winding mechanism.

[0006] A cutting device is installed above the guide device. When the pipe is transported to a specified length, the cutting device will cut off the portion of the pipe on the guide device.

[0007] The lower conveying assembly includes a first driver, a driving wheel, a first driven wheel, and a first transmission belt. The first driver drives and connects to the driving wheel. The driving wheel and the first driven wheel are connected by the first transmission belt. When the first transmission belt moves, it drives the pipes on the conveying section to be conveyed forward.

[0008] The upper conveying assembly includes a third driven wheel, a second driven wheel, and a second transmission belt. The third driven wheel and the second driven wheel are connected by the second transmission belt. When the first transmission belt drives the pipes in the conveying section to move forward, the pipes drive the second transmission belt to move.

[0009] A moving device is installed above the upper conveyor component. The moving device is connected to the upper conveyor component and drives the upper conveyor component to move up and down.

[0010] An encoder assembly for detecting the length of the pipe being conveyed is installed above the upper conveying assembly.

[0011] The guiding device includes a guide mounting plate, a guide member, and a guide fixing assembly. The guide member passes through the guide mounting plate and has a guide hole for the pipe to pass through. The guide fixing assembly is detachably mounted on the guide mounting plate and locks the guide member to the guide mounting plate.

[0012] The conduit assembly includes a guide wheel, a conduit, a second driver, a transmission assembly, and a transmission shaft. When the pipe is being transported, it passes through the guide wheel and the conduit in sequence. The second driver drives the transmission assembly, which is connected to the transmission shaft. The guide wheel is rotatably mounted on the transmission shaft, and the conduit is fixed on the transmission shaft. The second driver drives the conduit to rotate in sequence through the transmission assembly and the transmission shaft, so that the conduit drives the pipe to rotate up and down. When the pipe is transported to the winding mechanism, the conduit drives the pipe to rotate downward.

[0013] The cutting device includes a third driver and a cutting assembly. The third driver drives the cutting assembly to move up and down. When the cutting assembly moves down, it cuts the pipe portion on the guide device.

[0014] It also includes a moving component and a mounting frame. The traction device, guide device and conduit device are mounted on the mounting frame. The moving component drives the mounting frame to move left and right. When the pipe is conveyed to the winding mechanism, the moving component drives the mounting frame to move to the left.

[0015] This utility model's pipe winding machine incorporates a traction device, which includes an upper conveying component and a lower conveying component. When the upper conveying component moves downward, it presses the pipe onto the conveying section, while the lower conveying component drives the pipe forward. This allows the pipe to pass through the guiding device and the guide tube device in sequence before reaching the winding mechanism. By using the traction device to convey the pipe, the turntable does not require a high-power motor to ensure smooth pipe transport, thereby reducing motor costs and equipment costs. Furthermore, it reduces the tension of the turntable on the pipe, thus preventing pipe deformation. Attached Figure Description

The guide member 17 is provided with an insertion hole 34. One end of the plunger 32 passes through the plunger head 33 and is inserted into the insertion hole 34, thereby fixing the guide member 17 on the guide mounting plate 16. When the guide member 17 is disassembled, the plunger head 33 is unscrewed from the threaded hole 35, so that one end of the plunger 32 can be disengaged from the insertion hole 34. Then the guide member 17 can be removed from the through hole 36, and different specifications of guide members 17 can be replaced to adapt to pipes of different diameters.

[0035] The conduit device 2 includes a guide wheel 20, a conduit 21, a second driver 22, a transmission assembly, and a transmission shaft 23.
