Description

Technical Field

[0001] This invention belongs to the field of transformer manufacturing technology, and in particular relates to an alternating side-push type insulating paper tube removal machine. Background Technology

[0002] Insulating paper tubes play a crucial role in various transformer products. They are typically made by bonding and winding insulating paper. The winding process usually requires a mold to ensure the diameter and shape of the paper tube. After winding and curing, the paper tube needs to be removed from the mold. This removal operation demands high skill; the paper tube must not be damaged, and it should be removed as quickly as possible to improve efficiency. This operation is usually performed using specialized equipment. Most common paper tube removal machines currently use a slow, straight-pull operation. This method requires a high level of skill and patience from the operator; even slight carelessness can damage the paper tube. Summary of the Invention

[0003] This invention provides an alternating side-push type insulating paper tube removal machine to solve the problems mentioned in the background art.

[0004] The technical problem solved by this invention is achieved by the following technical solution: An alternating side-push type insulating paper tube removal machine includes a support part, a transmission part, a working part, a side-push part, and a clamping part. The transmission part is installed on the support part, the working part is installed between the transmission parts, the side-push part is installed between the transmission part and the working part, and the clamping part is installed around the working part.

[0005] The support unit includes a rear single support plate, a double support plate, a front single support plate, upper double lugs, and an adjusting threaded hole. The left side of the rear single support plate and the double support plate are hinged together to mount the drive gear. The right side of the double support plate and the front single support plate are hinged together to mount the transmission unit and are used to mount the working unit. The top of the front single support plate has upper double lugs, which connect with the adjusting ring of the side push unit. The lower part of the front single support plate has an adjusting threaded hole, in which an adjusting screw is threaded. The transmission unit includes a drive gear, a follower gear, a drive support shaft, a large spring, and a follower support shaft. The drive gear and the follower gear mesh and transmit power. The follower gear is mounted on the drive support shaft, driving the drive support shaft to rotate. The drive support shaft is hinged to the right side of the double support plate. The front end of the drive support shaft has a flange, which connects with the mold of the working unit. A large spring is mounted on the drive support shaft, located between the flange and the double support plate. The follower support shaft is hinged to the front single support plate, and a large spring is also mounted on the follower support shaft. The working part includes a mold and a paper tube. The paper tube is wound around the mold for demolding. Each end of the mold has a threaded hole for connection, which is bolted to a flange. The mold has a threaded hole facing the front single support plate, and a sleeve for the side pusher is installed in the threaded hole. The side pusher includes an adjusting ring, a sleeve, a telescopic rod, a small spring, and an adjusting screw. The adjusting ring has a through hole in the center, through which a follower support shaft passes. The top of the adjusting ring has an upper single ear, which is hinged to the upper double ear, enabling the installation of the adjusting ring and providing a pivot point for its rotation. The sleeve is installed in the threaded hole, and the telescopic rod is installed inside the sleeve. A small spring is installed between the telescopic rod inside the sleeve and the mold.

The clamping bolt connects and tightens the lower and upper retaining rings.

[0006] Furthermore, the active support shaft has a keyway, and a connecting key is used to connect the follower gear to the active support shaft.

[0007] Furthermore, since the follower gear will move laterally along with the active support shaft, in order to ensure that the follower gear always meshes with the active gear, the width of the active gear is designed to be no less than the entire stroke of the follower gear.

[0008] Furthermore, a limiting pin is installed at the end of the follower support shaft to limit the range of motion of the follower support shaft.

[0009] Furthermore, the lower retaining ring is supported on the ground by a support column.

[0010] The beneficial effects of this invention are: This invention is used for the removal of insulating paper tubes during the transformer manufacturing process. It has two sets of spring devices to buffer the removal operation and an adjustable side push mechanism that can slowly increase the tilt angle to gradually increase the lateral thrust of the mold, ensuring that the removal operation is carried out slowly and avoiding damage to the paper tube while removing it.

[0012] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0013] See Figures 1-3 The alternating side-push type insulating paper tube removal machine shown includes a support part 10, a transmission part 20, a working part 30, a side-push part 40, and a clamping part 50. The transmission part 20 is mounted on the support part 10, the working part 30 is mounted between the transmission parts 20, the side-push part 40 is mounted between the transmission part 20 and the working part 30, and the clamping part 50 is mounted around the working part 30.

[0014] The support part 10 includes a rear single support plate 11, a double support plate 12, a front single support plate 13, upper double ears 14, and an adjusting threaded hole 15. The rear single support plate 11 and the left side of the double support plate 12 are combined and hinged together to install the drive gear 21. The right side of the double support plate 12 and the front single support plate 13 are combined and hinged together to install the transmission part 20 and to install the working part 30. The top of the front single support plate 13 has an upper double ear 14, which is connected to the adjusting ring 41 of the side push part 40. The lower part of the front single support plate 13 has an adjusting threaded hole 15, in which an adjusting screw 45 is screwed.

[0015] The transmission unit 20 includes a driving gear 21, a follower gear 22, a driving support shaft 23, a large spring 24, and a follower support shaft 25. The driving gear 21 meshes with the follower gear 22 for transmission. The follower gear 22 is mounted on the driving support shaft 23, driving the driving support shaft 23 to rotate. The driving support shaft 23 is hinged to the right side of the double support plate 12. The driving support shaft 23 has a keyway 232, and a connecting key is used to connect the follower gear 22 to the driving support shaft 23. Since the follower gear 22 will move laterally with the driving support shaft 23, to ensure that the follower gear 22 always meshes with the driving gear 25... The gears 21 mesh, and the width of the driving gear 21 is designed to be no less than the entire stroke of the follower gear 22. The front end of the driving support shaft 23 has a flange 231, which docks with the mold 31 of the working part 30 to realize the installation of the working part 30. A large spring 24 is mounted on the driving support shaft 23, and the large spring 24 is located between the flange 231 and the double support plate 12. The follower support shaft 25 is hinged to the front single support plate 13, and a large spring 24 is also mounted on the follower support shaft 25. Under the combined action of the pair of large springs 24, the working part 30 always has a tendency to return to the center. A limit pin 251 is installed at the end of the follower support shaft 25 to limit the range of motion of the follower support shaft 25.

[0016] The working part 30 includes a mold 31 and a paper tube 32. The paper tube 32 is wound around the mold 31 for demolding. Each end of the mold 31 has a connecting threaded hole 311. The connecting threaded hole 311 is connected to the flange 231 by bolts, so as to realize the installation of the working part 30 between the active support shaft 23 and the follower support shaft 25. The mold 31 has a mounting threaded hole 312 facing the front single support plate 13. The sleeve 42 of the side push part 40 is installed on the mounting threaded hole 312.

[0017] The side-push part 40 includes an adjusting ring 41, a sleeve 42, a telescopic rod 43, a small spring 44, and an adjusting screw 45. The adjusting ring 41 has a through hole 411 in the center, through which the follower support shaft 25 passes. The top of the adjusting ring 41 has an upper single ear 412, which is hinged to the upper double ear 14 to realize the installation of the adjusting ring 41 and provide the pivot point for the swing of the adjusting ring 41. The sleeve 42 is installed in the mounting threaded hole 312, and the telescopic rod 43 is installed in the sleeve 42. The telescopic rod 43 in the sleeve 42 and the mold 31 are connected. A small spring 44 is installed. Under the action of the small spring 44, the telescopic rod 43 always presses against the adjusting ring 41. At the same time, if the telescopic rod 43 is pushed backward by the adjusting ring 41, the telescopic rod 43 transmits the force to the mold 31 through the small spring 44, generating a pushing force on the mold 31. Of course, it should be noted that the pushing force provided by the small spring 44 only plays an auxiliary and buffering role. The main force that actually separates the paper tube 32 from the mold 31 is generated by the lateral pushing force of the adjusting ring 41, which is buffered by the large spring 24. The adjusting screw 45 is installed on the adjusting threaded hole 15. The position of the adjusting screw 45 corresponds to the lower part of the adjusting ring 41. By adjusting the screw 45, the bottom of the adjusting ring 41 can be pushed forward, which, together with the side push part 40, pushes the lateral movement of the working part 30.

[0018] The clamping part 50 includes a lower clamping ring 51, an upper clamping ring 52, and a clamping bolt 53. The number of clamping parts 50 is reasonably configured according to the length of the paper tube 32. The lower clamping ring 51 is supported on the ground by the support column 511. The lower clamping ring 51 supports the paper tube 32 from the bottom of the paper tube 32. The upper clamping ring 52 presses the paper tube 32 from above. The clamping bolt 53 connects and tightens the lower clamping ring 51 and the upper clamping ring 52.

[0019] The working principle of this invention is as follows: The mold 31, which requires the paper tube to be detached, is connected between two flanges 231. The paper tube 32 is clamped by the clamping part 50. Under the action of the respective large springs 24, the mold 31 automatically returns to the center and the adjusting screw 45 is moved back to the final position. At this time, the adjusting ring 41 is kept hanging down by its own weight. The driving gear 21 drives the follower gear 22 to rotate. The follower gear 22 drives the driving support shaft 23 to rotate. The mold 31 rotates accordingly, and the side push part 40 rotates with the mold 31. Then, by adjusting the screw 45, the bottom of the adjusting ring 41 is pushed forward, and the adjusting ring 41 tilts. During the rotation of the mold 31, the adjusting ring 41 alternately compresses the telescopic rod 43. During the alternating compression, the small spring 44 applies a force to the mold 31. At this time, the force serves as a preparatory force for the paper tube 32 to detach from the mold 31. As the adjusting ring 41 tilts further, when the pushing of the adjusting ring 41 on the telescopic rod 43 reaches the extension limit of the telescopic rod 43, the force of the adjusting ring 41 through the telescopic rod 43 directly acts on the large spring 24 until the mold 31 can reciprocate under the action of the large spring 24, and the paper tube 32 is clamped by the clamping part 50. Then the paper tube detachment operation is completed.
