Typically, after the insulating paper tube is wound around a mold to a certain thickness and solidifies, it needs to be removed from the mold. While this operation may seem simple, it's actually quite demanding. Excessive force can easily damage the tube, while insufficient force can render it impossible to remove. Therefore, specialized equipment is ideal for removing insulating paper tubes. Summary of the Invention

[0017] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive disclosure of the present invention.

[0018] See also Figure 1-Figure 3 The rotary push-type transformer insulation paper tube stripping machine shown includes a support part 10, a driving part 20, a follower part 30 and a working part 40. The driving part 20 and the follower part 30 are both installed on the support part 10 and cooperate with each other, and the working part 40 is installed in the middle of the follower part 30.

[0019] The support part 10 includes an input bracket 11, an articulated bracket 12 and a clamping ring 13. The driving part 20 is hingedly installed on the input bracket 11. The articulated bracket 12 has a pair of follower cylinders 33 and follower mounting shafts 34 of the follower part 30, which are hingedly installed respectively. The clamping ring 13 is located in the middle. The clamping ring 13 clamps the paper tube 42. The bottom of the clamping ring 13 has a column 131 to fix the clamping ring 13 on the base.

[0020] The driving part 20 includes a driving shaft 21, a retaining spring groove 22, a driving gear disc 23, an input shaft 24 and a spring 25. The driving shaft 21 is installed on the input bracket 11. The driving shaft 21 can rotate and slide laterally on the input bracket 11. The rear end of the driving shaft 21 is provided with a retaining spring groove 22. A retaining spring is used in the retaining spring groove 22 to limit the front limit position of the driving shaft 21. The front end of the driving shaft 21 is provided with a driving gear disc 23. The tooth shape at the front end of the driving gear disc 23 is a wedge-shaped tooth. The rear end of the driving shaft 21 extends the input shaft 24, and the input shaft 24 is connected to the power source. The power source also needs to accommodate the lateral sliding of the input shaft 24 when driving the input shaft 24. The spring 25 is fitted on the driving shaft 21 and is located between the input bracket 21 and the driving gear disc 23. Under the action of the spring 25, the driving gear disc 23 always has a tendency to press the follower gear disc 312 forward.

[0021] The follower part 30 includes a push cylinder 31, a positioning screw 32, a follower cylinder 33 and a follower mounting shaft 34. The push cylinder 31 is hingedly mounted on the hinged bracket 12. The rear end of the push cylinder 31 is provided with a follower gear disc 312. The follower gear disc 312 is engaged with the driving gear disc 23 for transmission. The outer wall of the push cylinder 31 is provided with a spiral groove 311. The outer wall of the front end of the push cylinder 31 is fitted with the follower cylinder 33. The top of the follower cylinder 33 is provided with a threaded hole 331. The positioning screw 32 is installed in the threaded hole 331. The positioning screw 32 is embedded downward in the spiral groove 311. When the push cylinder 31 rotates, the positioning screw 32 cooperates with the spiral groove 311 to push the follower cylinder 33 forward. The front end of the follower cylinder 33 is provided with a flange 332. The flange 332 is docked with the working part 40. The follower mounting shaft 34 is hingedly mounted on the hinged bracket 12 on the rear side and connected to the working part 40 from the front end.

[0022] The working part 40 includes a winding mold 41 and a paper tube 42. The paper tube 42 is wound on the winding mold 41. The winding mold 41 has connecting holes 411 at both ends. The connecting holes 411 are connected to the flange 332 or the follower mounting shaft 34 to realize the installation of the winding mold 41 on the equipment.

[0023] The working principle of the present invention is as follows: first, the winding die 41 and the paper tube 42 that have been wound and are to be unwound are installed between the follower cylinder 33 and the follower installation shaft 34, and the paper tube 42 is clamped by the clamping ring 13. The power source drives the driving part 20 to rotate through the input shaft 24. Under the action of the spring 25, the active gear disc 23 of the driving part 20 is pressed against the follower gear disc 312. When the paper tube and the winding die have not yet been disengaged, the active gear disc 23 cannot drive the follower part 30 to rotate through the follower gear disc 312. This is because the active gear disc 23 compresses the spring 25 backwards, the active gear disc 23 retreats backwards, and the active gear disc 23 and the follower gear disc 312 are disengaged from each other. Open to avoid forcibly driving the follower part 30 to rotate. At the same time, the process will apply a pulsed load to the follower part 30, so that the load is gradually transmitted to the winding mold 41 until the winding mold 41 and the paper tube 42 are disengaged. At this time, the follower part 30 gradually rotates with the driving part 20. The rotation of the follower part 30 pushes the follower cylinder 33 to slide forward through the cooperation of the rotating groove 311 and the positioning screw 32, and the follower mounting shaft 34 moves accordingly until the winding mold 41 and the paper tube 42 are completely disengaged. Although the paper tube has not been completely removed at this time, it is relatively easy to remove the winding mold 41 and the paper tube 42 from each other after the two are disengaged.

[0024] The above embodiments primarily illustrate the rotary-push transformer insulating paper tube stripping machine of the present invention. While only a limited number of embodiments and technical features have been described, those skilled in the art will appreciate that the present invention may be implemented in numerous other forms without departing from its spirit and scope. Therefore, the presented embodiments are to be considered illustrative rather than restrictive, and the present invention may encompass various modifications and alternatives without departing from the spirit and scope of the invention as defined in the appended claims.
