Description

Technical Field

[0001] The present invention belongs to the technical field of transformer manufacturing, and particularly relates to a transformer insulating paper tube tube-removing machine. Background Art

[0002] Insulating parts are necessarily used in transformer products. Usually, there are many types of insulating parts used in type-I transformer products. One of the more common ones is the insulating paper tube. The insulating paper tube is usually made by winding insulating cardboard on a mold. After the winding is completed, the paper tube needs to be removed from the mold. At this time, if an operator manually operates to separate the paper tube from the mold, there will be certain difficulties, and usually, a suitable device needs to be used to complete it. The devices used for the tube-removing operation of insulating paper tubes vary in each transformer production site. Although they can all complete the tube-removing operation, most of them have cumbersome operations and a relatively large occupied length. Summary of the Invention

[0017] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented 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 invention more thorough and comprehensive.

[0018] Refer to Figures 1 - 3 the shown transformer insulating paper tube removing machine, which includes a base part 10, a driving part 20, an actuating part 30, a transmission part 40, a mold 50 and a paper tube 60. The transmission part 40 is respectively installed on the base part 10 and the actuating part 30. The driving part 20 is installed on the base part 10 and is connected to the actuating part 30. The mold 50 is installed on the top of the actuating part 30, and the paper tube 60 is wound around the mold 50.

[0019] The base part 10 includes a chassis 11, a first vertical groove 12, a dovetail groove 13, a side plate 14, a screw rod 15, an elastic strut 16, a pressure plate 17 and a nut 18. The chassis 11 is of a box-shaped structure, and the box-shaped structure of the chassis 11 can be an upper-opening or upper-side double-opening structure. The inner sides of the two side walls of the chassis 11 have a first vertical groove 12, the rear wall of the chassis 11 has a pair of dovetail grooves 13, and each of the outer sides of the two side walls of the chassis 11 is connected with a side plate 14. The screw rod 15 passes through the top of the side plate 14, and the screw rod 15 can slide horizontally on the side plate 14. The part of the screw rod 15 located inside the side plate 14 is installed with a nut 18. Rotating the nut 18 can adjust the socket position of the screw rod 15 on the side plate 14. It should be noted here that there is no thread on the side plate 14. The inner side of the screw rod 15 is connected to the pressure plate 17 through a plurality of elastic struts 16, and the pressure plate 17 clamps the paper tube 60. It should be supplemented here that the elasticity of the elastic strut 16 is very limited, and it is mainly used to provide the clamping force of the pressure plate 17 on the paper tube 60. Therefore, the elasticity of the elastic strut 16 is small, and it can even be considered as close to a rigid connection.

[0020] The driving part 20 includes a power source 21, a stud 22 and lugs 23. The power source 21 is installed on the bottom surface of the chassis 11 through the evenly distributed lugs 23 around it. The power source 21 is connected upward to the stud 22, and the stud 22 is connected to the first frame 31 of the actuating part 30 through threads. It should be noted here that the power source 21 provides rotational input, and the connection between the power source 21 and the stud 22 can be configured with transmission devices such as couplings or speed reducers as required.

[0021] The actuating part 30 includes a first frame 31, a second frame 32 and a third frame 33. The first frame 31 is slidably sleeved on the chassis 11, the second frame 32 is slidably sleeved in the first frame 31, and the third frame 33 is slidably sleeved in the second frame 33.

[0022] The overall structural form of the first frame 31 is similar to that of the chassis 11. There is a boss 311 on the bottom plate of the first frame 31, and the stud 22 is screwed on the boss 311. There are gear grooves 312 on both side walls of the first frame 31, and the first gear set 43 is installed in the gear grooves 312. There are also second vertical grooves 313 on the inner sides of both side walls of the first frame 31. In addition, there is a dovetail groove on the inner side of the rear side wall of the first frame 31 for sleeving with the second frame 32, and a dovetail slider on the outer side of its rear side wall for sleeving with the chassis 11.

[0023] The second frame 32 has no bottom plate, and other structures are similar to those of the first frame 31. The positions of each technical feature are matched with the transmission part 40.

[0024] The top of the third frame 33 has a top plate 331. The top plate 331 is connected upward to the mold 50. There are connection holes on the top plate 331 for connecting with the mold 50, and there are also limit blocks for positioning with the mold 50.

[0025] The transmission part 40 includes a first rack set 41, a second rack set 42, a first gear set 43 and a second gear set 44. The first rack set 41 is respectively installed on the chassis 11 and the second frame 32. The first gear set 43 is installed in the gear grooves 312 of the first frame 31, and the first gear set 43 meshes with the first rack set 41. The second rack set 42 is respectively installed on the first frame 31 and the third frame 33. The second gear set 44 is installed on the second frame 32, and the second gear set 44 meshes with the second rack set 42.

[0026] The working principle of the present invention is as follows: First, the mold 50 and the paper tube 60 wound thereon are connected and installed on the top plate 331, and the nut 18 is tightened so that the pressing piece 17 clamps the paper tube 60. The power source 21 is started to drive the stud 22 to rotate. The stud 22 drives the first frame 31 to move upward. At this time, the first gear set 43 pushes the second frame 32 to move upward through the first rack set 41, further driving the second gear set 44 to drive the third frame 33 to move upward through the second rack set 42. The third frame 33 pushes the mold 50 to move upward through the top plate 331 thereon. Since the paper tube 60 is clamped by the pressing piece 17, the separation of the paper tube 60 from the mold 50 is realized during the upward movement of the mold 50. Of course, it should be supplemented here that in the initial stage of pushing the mold 50 to move upward, a slow speed should be adopted as much as possible to avoid damaging the paper tube 60.

[0027] The above embodiments mainly illustrate the transformer insulating paper tube tube-removing machine of the present invention. Although only a limited number of embodiments and technical features are described therein, those skilled in the art should understand that the present invention can be implemented in many other forms without departing from its gist and scope. Therefore, the embodiments shown are regarded as illustrative rather than restrictive, and the present invention may cover various modifications and alternative solutions without departing from the spirit and scope of the present invention defined by the appended claims.
