Description

Technical Field

[0001] The invention relates to a winding pipe manufacturing technology, in particular to an axially embedded anti-cracking plastic winding pipe winding machine. Background Art

[0002] Traditional plastic winding pipes are prone to cracking during use. Studies have found that the cracks are located at the joints. The traditional spiral winding pipes only treat the joints by hot pressing welding or glue injection. Relatively speaking, the joints are relatively weak and are more likely to crack when under pressure.

[0003] We have made improvements on the structure of traditional plastic winding tubes by setting protrusions and grooves on both sides of the plastic profile. By using the interlocking of the protrusions and grooves, we can reinforce the joints of the plastic winding tubes and prevent them from cracking. However, the structural changes have brought difficulties to the spinning of the plastic profiles to form plastic winding tubes. Obviously, traditional winding machines cannot simultaneously achieve the interlocking of the protrusions and grooves when spinning the plastic profiles. Summary of the invention

[0004] In order to solve the above problems, the present invention proposes an axially embedded anti-cracking plastic winding tube winding machine, which can achieve the embedding of protrusions and grooves when winding plastic profiles.

[0005] The technical solution of the present invention:

[0006] A winding machine for axially engaging and crack-proof plastic winding tubes, the winding machine comprising a winding machine body, a plastic profile is wound on the winding machine body to form a plastic winding tube; the plastic profile has a protrusion on one side and a groove on the other side, the protrusion matches the groove, when the plastic profile is wound, the protrusion extends into the groove and is axially engaged with it; the winding machine also comprises a front side pressure roller, the front side pressure roller is installed on the winding machine body, and is located at the starting point of the plastic profile winding;

[0007] When the plastic profile is rolled, the front pressure roller is directly opposite to and against the plastic profile, axially extruding the plastic profile, forcing the protrusion to extend into the groove and axially engage with it.

[0008] When the plastic profile is rolled, the gap between the front pressure roller and the formed plastic winding tube is smaller than the width of the plastic profile.

[0009] There are several front side pressing rollers in total, and the front side pressing rollers are arranged in a row along the spiral direction of the plastic profile, and the diameters of the front side pressing rollers gradually increase or the gaps between the front side pressing rollers and the formed plastic winding tubes gradually decrease.

[0010] The wrapping machine also includes a slide and a rear pressure roller, wherein the slide is installed below the main body of the wrapping machine (preferably a guide rail and guide wheel design is adopted, the guide wheel is installed on the slide, at least one of which is an active guide wheel connected to a driving device installed on the slide), and the rear pressure roller is installed on the slide;

[0011] When the plastic sheet is rolled, the slide actively moves forward axially, driving the rear pressure roller to move forward axially, and the rear pressure roller always abuts against the end of the formed plastic winding tube.

[0012] A plurality of supporting rollers are installed on the slide, and the supporting rollers are used together to form a plastic winding tube.

[0013] The advantages of the present invention are reasonable design and simple structure. A front pressure roller is added to axially extrude the plastic profile by the front pressure roller, so that the axial engagement of the protrusion and the groove is achieved when the plastic profile is rolled. The diameter of the front pressure roller is gradually increased or the gap between the front pressure roller and the formed plastic winding tube is gradually reduced, so that the axial extrusion is changed into a gradual process, so that the protrusion can be extruded into the groove more smoothly.
