DETAILED DESCRIPTION

[0018] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the related drawings. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0019] Referring to Figures 1-4 The flexible pipe removal device for the insulation paper tube is shown, which includes a base part 10, a winding mold 20, a paper tube 30 and a driving part 40, the winding mold 20 is placed on the base part 10, the winding mold 20 has the paper tube 30 completed winding, and the driving part 40 is connected with the winding mold 20.

[0020] The base part 10 comprises a support 11, a support arm 12 and a clamp 13. The support 11 has a pair of supports 11, which respectively support the winding mold 20 from both ends of the winding mold 20, and the winding mold 20 rolls on the support 11. The support arm 12 is connected to the clamp 13 upwardly, and the clamp 13 is clamped with the semicircle on the top of the support arm 12.

[0021] The end surface of the winding mold 20 has a threaded hole (not shown in the figure) which is connected to the driving part 40.

[0022] The driving part 40 comprises an input disc 41, a floating chuck 42, a spring 43 and a transmission member 44. The floating chuck 42 is installed on the transmission member 44 through the spring 43. The input disc 41 is connected to a power source outwardly. The spring 43 pushes the floating chuck 42 to the input disc 41, so that the floating chuck 42 is always pressed tightly to the input disc 41.

[0023] It should be noted that the power source connected to the input disc 41 should have the ability of bidirectional rotation switching.

[0024] The input disc 41 comprises a hexagonal head 411, a rotating shaft 412 and a wedge-shaped sliding tooth 413. The hexagonal head 411 is connected to the power source. Of course, the specific connection form of the input disc 41 can be adjusted and designed according to the output structure of the power source. The hexagonal head 411 is connected to the main body of the input disc 41 through the rotating shaft 412. The wedge-shaped sliding tooth 413 is uniformly distributed on the circumference of the back surface of the input disc 41. One side of the wedge-shaped sliding tooth 413 is an inclined angle, and the other side is a flat stage.

[0025] The floating chuck 42 comprises a protruding tooth 421 and a circular groove 422. The protruding tooth 421 is uniformly distributed on the circumference of the floating chuck 42. The protruding tooth 421 cooperates with the wedge-shaped sliding tooth 413 to move. When the rotating direction of the wedge-shaped sliding tooth 413 is the inclined angle, the inclined angle part has two components of the pushing force to the protruding tooth 421. One is the tangential component to push the protruding tooth 421 to rotate, and the other is the axial component to push the protruding tooth 421 to retreat after compressing the spring 43. When the tangential component is not enough to push the protruding tooth 421 to rotate, the axial component pushes the protruding tooth 421 to retreat after compressing the spring 43, and the protruding tooth 421 passes over the wedge-shaped sliding tooth 413 to avoid damage to the paper tube 30 due to forced rotation. When the inclined angle part can push the protruding tooth 421 to rotate, the wedge-shaped sliding tooth 413 is reversed, and the flat stage of the wedge-shaped sliding tooth 413 directly pushes the protruding tooth 421 to rotate several turns to ensure that the paper tube 30 and the winding mold 20 are completely separated, and the paper tube separation operation is completed. The circular groove 422 is uniformly distributed on the back surface of the floating chuck 42. The spring 43 is installed in the circular groove 422.

[0026] The transmission member 44 comprises an inner cavity 441, tooth grooves 442, a connecting shaft 443, a connecting disc 444 and connecting holes 445, the tooth grooves 442 are uniformly distributed around the inner cavity 441, the loose chuck 42 is fitted and installed in the inner cavity 441, the convex teeth 421 are fitted and installed in the tooth grooves 442, the spring 43 is installed between the loose chuck 42 and the inner cavity 441, the middle part of the transmission member 44 has the connecting shaft 443, the connecting shaft 443 is connected with the connecting disc 444 at the back, and the connecting disc 444 is connected with the winding mold 20 through the connecting holes 445.

[0027] It should be noted here that the driving part 40 also needs to be supported as needed, and hinge supports are needed at the rotating shaft 412 and the connecting shaft 443.

[0028] The working principle of the present application is that the power source drives the input rotating disc 41 to rotate counterclockwise in the direction shown in the figure, and then the inclined angle part of the wedge-shaped sliding tooth 413 acts on the convex teeth 421. Figure 4 When the tangential component is not enough to drive the convex teeth 421 to rotate, the axial component drives the convex teeth 421 to compress the spring 43 and retreat, and the convex teeth 421 pass through the wedge-shaped sliding tooth 413 to avoid damage to the paper tube 30 due to forced rotation, and when the inclined angle part can drive the convex teeth 421 to rotate, the wedge-shaped sliding tooth 413 is reversed, and the flat stage of the wedge-shaped sliding tooth 413 directly drives the convex teeth 421 to rotate several turns to ensure that the paper tube 30 and the winding mold 20 are completely separated, and the paper tube separation operation is completed.

[0029] When the paper tube 30 and the winding mold 20 are finally separated, the driving part 40 is disconnected, the winding mold 20 is lifted to a vertical state using a lifting tool, and the paper tube 30 can be easily removed.

[0030] The above embodiments mainly illustrate the flexible paper tube separation device of the present application. Although only limited embodiments and technical features are described, those skilled in the art should understand that the present application can be implemented in many other forms without deviating from the main idea and scope. Therefore, the embodiments shown are regarded as illustrative rather than limiting, and the present application can cover various modifications and alternatives without deviating from the spirit and scope of the present application defined in the appended claims.
