[0043] Example 1

[0044] Reference Figure 1~Figure 3 A plastic composite pipe reinforcement layer winding device is proposed, which is used to wind a reinforcement layer onto a pipe body 1, comprising:

[0045] Workbench 2;

[0046] A reinforcing layer turntable 3 is rotatably arranged on the workbench 2, a first through hole 4 is provided at the center of the reinforcing layer turntable 3, and a plurality of reinforcing layer mounting shafts 5 are provided on the reinforcing layer turntable 3;

[0047] The annular mounting frame 6 is arranged on the reinforcing layer turntable 3;

[0048] The reinforcing layer winding wheel 7 is rotatably arranged on the annular mounting frame 6. The reinforcing layer winding wheel 7 rotates while following the rotation of the annular mounting frame 6. The rotation direction of the reinforcing layer winding wheel 7 itself is opposite to the rotation direction of the annular mounting frame 6. The reinforcing layer winding wheel 7 has at least two second through holes 8 distributed at intervals. The reinforcing layer winding wheel 7 is distributed in a circle along the circumferential direction of the annular mounting frame 6.

[0049] In this embodiment, in order to solve the problem that the strength of the plastic composite pipe in the related art needs to be improved, a pre-step is set, that is, the two reinforcement layers are firstly wound into a twist shape to form a basic unit, and then a plurality of basic units are wound into layers and wound onto the inner pipe. In this way, the strength of the formed pipe body 1 can be greatly improved with the help of the twist-shaped basic unit, and the deformation can be reduced.

[0050] The specific working principle is: the tube body 1 passes through the first through hole 4 at the center of the reinforcement layer turntable 3 and is driven forward by the traction machine. Each of the multiple reinforcement layer mounting shafts 5 on the reinforcement layer turntable 3 is equipped with a reinforcement layer roll body, and the reinforcement layer turntable 3 can be unwound by rotation. The multiple reinforcement layer roll bodies are grouped into two, corresponding to a reinforcement layer winding wheel 7. The two reinforcement layers respectively pass through the two second through holes 8 on the corresponding reinforcement layer winding wheel 7. Since the reinforcement layer winding wheel 7 rotates while following the rotation of the annular mounting frame 6, and the direction of the reinforcement layer winding wheel 7 itself is opposite to that of the annular mounting frame 6, the reverse rotation of the reinforcement layer winding wheel 7 will wind the two reinforcement layers into a twist shape, and then wind them onto the tube body 1, which greatly improves the strength of the tube body 1 after forming.

[0051] It should be noted that the two reinforcement layers wound into a twist shape are initially manually pulled onto the tube body 1 , and after being fixed, the twist-shaped basic units can be continuously and automatically outputted.

[0052] Furthermore, it also includes,

[0053] The annular guide member 9 and the reinforcing layer winding wheel 7 have a tooth portion 10 along the circumferential direction. The annular guide member 9 is arranged on the workbench 2 and has a tooth portion 2 11 inside along the circumferential direction. The tooth portion 10 is meshed with the tooth portion 2 11 .

[0054] In this embodiment, in order to realize the reverse rotation of the reinforcement layer winding wheel 7, an annular guide member 9 is also arranged on the periphery of the annular mounting frame 6. The annular guide member 9 can adopt an internal gear ring and be fixed on the workbench 2. Since the reinforcement layer winding wheel 7 has the freedom of rotation on the annular mounting frame 6, it can realize its own reverse rotation under the engagement with the internal gear ring, thereby twisting the two reinforcement layers into a twist shape.

[0055] Furthermore, it also includes,

[0056] A guide ring 12 is provided on the reinforcement layer turntable 3 and is located on one side of the annular mounting frame 6;

[0057] The limiting protective shell 13 is arranged on the reinforcing layer turntable 3, is hollow inside, and covers the outer periphery of the first through hole 4. The tube body 1 passes through the first through hole 4 from the inside of the limiting protective shell 13. The limiting protective shell 13 has a circle of limiting holes 14, and the limiting holes 14 are located on the other side of the annular mounting frame 6. The reinforcing layer passes through the guide ring 12, the second through hole 8 and the limiting holes 14 in sequence, and is wrapped around the tube body 1.

[0058] In this embodiment, in order to guide and protect the reinforcement layer, a guide ring 12 and a limiting protective shell 13 are also provided on the device. The guide ring 12 is located on one side of the annular mounting frame 6 to help the reinforcement layer to transition smoothly. The limiting protective shell 13 is sleeved on the periphery of the first through hole 4 and contains a circle of limiting holes 14, so that the pipe body 1 can pass smoothly through it, while limiting the path of the reinforcement layer to ensure that it is accurately wound on the pipe body 1.

[0059] Furthermore, the limiting protection shell 13 also has a guiding transition surface 15 , and the reinforcing layer passes through the limiting hole 14 and then is wound around the pipe body 1 through the guiding transition surface 15 .

[0060] In this embodiment, the limiting protective shell 13 is designed with a guiding transition surface 15 to ensure that the reinforcing layer can smoothly transition to the surface of the tube body 1 after passing through the limiting hole 14 to avoid distortion or damage during the winding process.

[0061] Furthermore, it also includes,

[0062] The base 16 is disposed on the workbench 2 and is located on one side of the limiting protection shell 13;

[0063] A hand screw rod 17 is arranged on the base 16, and the hand screw rod 17 has two nut seats with opposite moving directions;

[0064] There are two protection wheels 18, which are rotatably arranged on two nut seats and are located on both sides of the tube body 1 respectively.

[0065] In this embodiment, the setting of the hand-cranked screw rod 17 can manually adjust the distance between the two protection wheels 18 according to the diameter of the tube body 1, thereby playing the role of a protection and limiting reinforcement layer.

[0066] Furthermore, it also includes,

[0067] There are multiple supporting wheels 19 , all of which are rotatably disposed on the workbench 2 and are used to support the reinforcement layer turntable 3 .

[0068] In this embodiment, in order to maintain the smooth rotation of the reinforcing layer turntable 3, a plurality of supporting wheels 19 are installed on the workbench 2 to support the turntable, reduce friction, and improve overall efficiency.

[0069] Example 2

[0070] Reference Figure 4~Figure 5, compared with Example 1, further comprising,

[0071] The glue liquid input pipe 20 is arranged on the annular guide member 9. The annular guide member 9 has a first channel 21. The glue liquid input pipe 20 is communicated with the first channel 21. The tooth portion 11 has a second channel 22. The second channel 22 is communicated with the first channel 21.

[0072] The reinforcing layer winding wheel 7 has a third channel 23 , which is connected to the second through hole 8 . After the second tooth portion 11 is meshed with the first tooth portion 10 , the third channel 23 is connected to the second channel 22 .

[0073] Furthermore, it also includes,

[0074] The automatic opening and closing head 24 is movably disposed in the second passage 22 and opens or closes the second passage 22 after moving.

[0075] Furthermore, it also includes,

[0076] The elastic member 25 has one end acting on the annular guide member 9 and the other end acting on the automatic opening and closing head 24 , so as to provide the automatic opening and closing head 24 with a force to close the second channel 22 .

[0077] Furthermore, the cross sections of the second passage 22 and the automatic opening and closing head 24 are both trapezoidal.

[0078] In this embodiment, in order to save glue, a glue inlet pipe 20 is also provided on the annular guide member 9. The glue is introduced into the glue inlet pipe 20, flows into the first channel 21, and then flows into the second channel 22. The elastic member 25 can be a spring. Since the cross-sections of the second channel 22 and the automatic opening and closing head 24 are both trapezoidal, under the action of the elastic member 25, the side end face of the automatic opening and closing head 24 is tightly attached to the inner wall of the second channel 22, the port of the second channel 22 is blocked, and the glue does not leak. When the reinforcing layer is wound around the wheel 7, the reinforcing layer 22 is wound around the wheel 7. When the tooth part 10 and the tooth part 2 11 of the annular guide 9 are meshed, the automatic opening and closing head 24 will be pushed back into the second channel 22. Since the cross-sections of the second channel 22 and the automatic opening and closing head 24 are both trapezoidal, the side end surface of the automatic opening and closing head 24 will be separated from the inner wall of the second channel 22, so that the glue input pipe 20, the first channel 21, the second channel 22, the third channel 23 and the second through hole 8 are connected in sequence, and the glue drips onto the reinforcement layer in the second through hole 8, completing the fixed-point and quantitative application of the glue, which can greatly reduce the waste of the glue. For the replenishment of the glue, the time when the glue is consumed to a certain amount can be measured in advance, and replenishment can be performed according to the preset time.

[0079] In summary, in order to achieve the composite winding of the reinforcing layer and the glue, the annular guide 9 has a built-in first channel 21 and is connected to the glue input pipe 20. At the same time, the tooth part 11 is designed with a second channel 22, which is connected to the third channel 23 of the winding wheel to form a complete liquid transmission system to ensure that the glue can be evenly coated on the reinforcing layer. An automatic opening and closing head 24 is set in the second channel 22, and the flow of the glue is controlled by its movement to achieve precise application of the glue. In order to ensure the reliable closure of the automatic opening and closing head 24, an elastic member 25 is used to connect the annular guide 9 and the opening and closing head to provide the necessary closing force. Considering the stability and controllability of the flow of the glue, the cross-sections of the second channel 22 and the automatic opening and closing head 24 are both designed to be trapezoidal, which is conducive to the control of the flow of the glue, reduces the risk of blockage, and improves the operational flexibility and reliability of the entire system.
