[0022] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0023] Please see Figures 1-4 An automatic pipe threading device for rubber and plastic insulation pipes includes: a support frame 1, on which a limit clamping assembly and a driving assembly are arranged from left to right. The limit clamping assembly includes a limit box 2, in which a limit hole 21 and a sliding groove 22 are opened and communicate with each other. The limit hole 21 is a through hole penetrating the limit box 2. The upper surface of the inner cavity of the sliding groove 22 is an inclined surface. A trapezoidal slider 5 is slidably arranged in the sliding groove 22. A limit sleeve 9 is arranged in the limit hole 21. The outer side of the limit sleeve 9 is fixedly connected to the inner wall of the limit hole 21. The insulation pipe 8, which is held by the trapezoidal slider 5, is fixedly connected to the limit hole 21 and the limit sleeve 9 is covered with the insulation pipe 8. The inclined angle of the top of the trapezoidal slider 5 is the same as the inclined angle of the inclined surface of the sliding groove 22, so that the trapezoidal slider 5 can slide along the inclined surface of the sliding groove 22, and the bottom of the trapezoidal slider 5 moves vertically downward, so that the part of the insulation pipe 8 in contact with the trapezoidal slider 5 is subjected to the same compressive force, thereby improving the stability of the insulation pipe 8 being clamped.

[0024] Specifically, this utility model uses a trapezoidal slider 5 to slide within a groove 22 and, in conjunction with a limiting sleeve 9, to lift the wall of the insulation pipe 8, thereby achieving different degrees of compression on the wall of the insulation pipe 8, and thus clamping and locking the insulation pipe 8. Under the action of the driving component, the inner tube 7 passes through the limiting sleeve 9 and directly enters the insulation pipe 8, completing the automated sleeve work of the inner tube 7, thereby reducing costs and increasing efficiency.

[0025] Furthermore, a fixing block 6 is fixedly connected to the limiting box 2. The fixing block 6 is fixedly installed at the outlet position of the slide groove 22 and is tightened onto the limiting box 2 by screws. A screw rod 61 is threaded into the fixing block 6. A T-shaped slide groove 51 is provided on the side of the trapezoidal slider 5 near the fixing block 6. A slide plate 62 is slidably disposed in the T-shaped slide groove 51. The screw rod 61 passes through the T-shaped slide groove 51 and is fixedly connected to the slide plate 62. (Reference) Figure 2 The slide plate 62 is limited within the T-shaped slide groove 51. As the screw 61 is rotated, the screw 61 drives the slide plate 62 to rotate within the T-shaped slide groove 51. At the same time, it pushes or pulls the trapezoidal slider 5 to move along the inclined surface of the slide groove 22, thereby completing the clamping work of the insulation pipe 8.

[0026] Furthermore, the corners of the trapezoidal slider 5 and the inner wall of the slide groove 22 are all rounded. By rounding the corners, the friction of the trapezoidal slider 5 when sliding in the slide groove 22 can be reduced, and workers can be prevented from being injured by hitting the corners.

[0027] Furthermore, the drive assembly includes a drive box 3, inside which a set of drive wheels 31 are rotatably arranged. The drive wheels 31 have an arc groove in the middle for placing the inner tube 7, and all of them are rounded to protect the outer surface of the inner tube 7 from wear to the greatest extent. At the same time, the two drive wheels 31 hold the inner tube 7. As the motor drives the drive wheels 31 to rotate, the inner tube 7 is pushed. A set of guide wheels 32 are arranged on each side of the set of drive wheels 31. The two sets of guide wheels 32 mainly guide the inner tube 7 and straighten the bent inner tube 7, making it easier to insert the inner tube 7 into the insulation pipe 8.

[0028] Furthermore, a coil 4 is provided on the top of the support frame 1. The coil 4 is located on the right side of the drive assembly. The inner tube 7 is wound and collected on the coil 4. When the inner tube 7 is threaded through the coil, it is pulled out from the coil 4 and, after being driven by the drive assembly and straightened, is threaded into the insulation pipe 8.

[0029] In this utility model, reference Figures 1 to 4 First, thread the screw 61 onto the fixing block 6 and weld the sliding plate 62 onto the screw 61. Next, slide the sliding plate 62 into the T-shaped groove 51, then place the trapezoidal slider 5 into the groove 22, and lock the fixing block 6 onto the limiting box 2 with screws. Next, insert the insulation tube 8 into the limiting hole 21 until the insulation tube 8 is fitted onto the outside of the limiting sleeve 9. Then, turn the screw 61 so that the screw 61 pushes the trapezoidal slider 5 to the right along the inclined surface of the groove 22, so that the trapezoidal slider 5 abuts against the wall of the insulation tube 8, thereby clamping and locking the insulation tube 8. Finally, insert the inner tube 7 into the limiting sleeve 9 after passing through a set of guide wheels 32, a set of drive wheels 31, and another set of guide wheels 32 in sequence. Start the drive wheel 31, which drives the inner tube 7 to continuously penetrate into the insulation tube 8.

[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
