Description

Technical Field

[0001] The present invention relates to the technical field of lead insulation wrapping for transformer products, and particularly to a crepe paper winding machine. Background Art

[0002] During the transformer assembly process, lead insulation wrapping is a very crucial assembly process. According to the requirements of insulation wrapping, crepe paper is generally wound in a semi-overlapping manner with two layers starting from the beginning. However, the paper reels actually purchased are all single-layer crepe paper. Before operation, it is necessary to rewind the large single-layer crepe paper reel into a double-layer small paper reel. There is no suitable tool for this operation, and it requires two people to cooperate, resulting in low winding efficiency. For this reason, we propose a crepe paper winding machine. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that in the prior art, the crepe paper used for lead insulation wrapping during the transformer assembly process is generally wound in a semi-overlapping manner with two layers starting from the beginning, but the paper reels actually purchased are all single-layer crepe paper. Before operation, it is necessary to rewind the large single-layer crepe paper reel into a double-layer small paper reel. There is no suitable tool for this operation, and it requires two people to cooperate, resulting in low winding efficiency, and to propose a crepe paper winding machine.

[0004] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0005] A crepe paper winding machine includes a base. A first fixing frame is fixedly provided on the upper left side of the base. A winding reel is rotatably provided on the first fixing frame through a first rotating shaft. A clamping cover is provided at the upper end of the winding reel. A slot is opened at the upper end of the winding reel. A first spring is fixedly provided on the inner wall of the bottom end of the slot. An insertion rod is fixedly provided at the upper end of the first spring. The upper end of the insertion rod is fixedly provided on the clamping cover. A groove is opened on the lower left side of the clamping cover. A second rotating shaft is rotatably provided in the groove. A cam is fixedly provided on the shaft wall of the second rotating shaft. A limiting mechanism is provided at the upper end of the cam. A second fixing frame is fixedly provided on the upper right side of the base. Two paper feeding reels are rotatably provided at the left and right ends of the second fixing frame through a third rotating shaft.

[0006] Preferably, the limiting mechanism includes a clamping block and a second spring. A limiting groove is opened on the inner wall of the upper end of the groove. The clamping block is slidably provided inside the limiting groove. The lower end of the clamping block extends out of the limiting groove and matches the cam. The second spring is fixedly provided between the clamping block and the inner wall of the top end of the limiting groove. A pulling mechanism is provided on the side wall of the clamping block.

[0007] Preferably, the pulling mechanism includes a fixed block, a grip rod and a handle. The fixed block is fixedly arranged on the side wall of the clamping block. A strip-shaped opening is formed in the side wall of the limiting groove. The other end of the fixed block extends out of the strip-shaped opening and is fixedly connected with the grip rod. The handle is fixedly arranged on the side wall of the clamping cover. The position of the grip rod corresponds to the position of the handle.

[0008] Preferably, two limiting blocks are fixedly arranged on the side wall of the clamping cover. The two limiting blocks are located at the lower end of the handle. A strip-shaped sliding groove is formed in the limiting block. The grip rod penetrates through the strip-shaped sliding groove and is slidably connected with the inner wall of the strip-shaped sliding groove.

[0009] Preferably, the insertion rod is slidably connected with the inner wall of the insertion slot, and both the insertion rod and the insertion slot are square.

[0010] Preferably, one end of the second rotating shaft penetrates through the groove and is fixedly provided with a rotating handle.

[0011] Preferably, one end of the first rotating shaft penetrates through the first fixing frame and is fixedly provided with a crank.

[0012] Compared with the prior art, the present invention provides a crepe paper winder, which has the following beneficial effects:

[0013] 1. For this crepe paper winder, by rotating the rotating handle to drive the cam to rotate, the upper end of the convex part of the cam abuts against the clamping block, and the lower end of the convex part of the cam supports the entire clamping cover. The clamping block stably limits the cam through the second spring, so as to conveniently separate the clamping cover from the paper winding roll.

[0014] 2. For this crepe paper winder, by holding the handle and hooking the grip rod with fingers, the grip rod can be conveniently pulled up. By pulling up the grip rod, the clamping block no longer limits the cam. By rotating the rotating handle to drive the cam to rotate, the cam no longer supports the clamping cover. By pulling the insertion rod downward through the first spring, the insertion rod pulls the clamping cover downward, so as to conveniently clamp and fix the crepe paper head on the paper winding roll.

[0015] 3. For this crepe paper winder, by rotating the crank to drive the paper winding roll to rotate, the single-layer crepe paper on the two paper feeding rolls can be conveniently wound around the paper winding roll in a double layer, which not only saves manpower but also improves the winding efficiency of the winder.

[0016] The parts not involved in this device are the same as or can be implemented by the prior art. The operation of the present invention is simple and has strong practicability. It not only saves manpower but also improves the winding efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

A slot is opened above the paper winding roll 3. A first spring 14 is fixedly provided on the inner wall of the bottom end of the slot. The upper end of the first spring 14 is fixedly provided with an inserting rod 13. The upper end of the inserting rod 13 is fixedly provided on the clamping cover 4. The inserting rod 13 is slidably connected to the inner wall of the slot, and both the inserting rod 13 and the slot are square. A groove is opened on the lower left side of the clamping cover 4. A second rotating shaft 8 is rotatably provided in the groove. A cam 9 is fixedly provided on the shaft wall of the second rotating shaft 8. A limiting mechanism is provided above the cam 9. One end of the second rotating shaft 8 penetrates through the groove and is fixedly provided with a turning handle 18. A second fixing frame 2 is fixedly provided on the upper right side of the base 1. Two paper feeding rolls 6 are rotatably provided at the left and right ends of the second fixing frame 2 through a third rotating shaft 5.

[0024] The limiting mechanism includes a clamping block 10 and a second spring 11. A limiting groove is provided on the inner wall at the upper end of the groove. The clamping block 10 is slidably arranged inside the limiting groove. The lower end of the clamping block 10 extends out of the limiting groove and matches the cam 9. The second spring 11 is fixedly arranged between the clamping block 10 and the inner wall at the top of the limiting groove. A pulling mechanism is provided on the side wall of the clamping block 10.

[0025] The pulling mechanism includes a fixed block 12, a grip rod 15 and a handle 17. The fixed block 12 is fixedly arranged on the side wall of the clamping block 10. A strip-shaped opening is provided on the side wall of the limiting groove. The other end of the fixed block 12 extends out of the strip-shaped opening and is fixedly connected to the grip rod 15. The handle 17 is fixedly arranged on the side wall of the clamping cover 4. The position of the grip rod 15 corresponds to the position of the handle 17. Two limiting blocks 16 are fixedly arranged on the side wall of the clamping cover 4. The two limiting blocks 16 are located at the lower end of the handle 17. A strip-shaped sliding groove is provided on the limiting block 16. The grip rod 15 passes through the strip-shaped sliding groove and is slidably connected to the inner wall of the strip-shaped sliding groove.

[0026] In the present invention, during actual use, the staff first drives the cam 9 to rotate by rotating the rotating handle 18, so that the upper end of the convex part of the cam 9 presses against the clamping block 10, and the lower end of the convex part of the cam 9 supports the entire clamping cover 4. The clamping block 10 stably limits the cam 9 through the second spring 11, so as to conveniently separate the clamping cover 4 from the paper winding roll 3.

After the placement is completed, the staff holds the handle 17 and hooks the grip rod 15 with fingers to conveniently lift the grip rod 15. By lifting the grip rod 15, the fixed block 12 is driven to move upward. By the upward movement of the fixed block 12, the clamping block 10 is driven to move upward so that the clamping block 10 no longer limits the cam 9. At this time, the staff drives the cam 9 to rotate by rotating the rotating handle 18, so that the cam 9 no longer supports the clamping cover 4. At this time, the first spring 14 pulls the inserting rod 13 to move downward, and the inserting rod 13 pulls the clamping cover 4 to move downward, so as to conveniently clamp and fix the crepe paper head on the paper winding roll 3. After the clamping is completed, the staff drives the paper winding roll 3 to rotate by rotating the crank 19. By the rotation of the paper winding roll 3, the single-layer crepe paper on the two paper feeding rolls 6 is conveniently wound around the paper winding roll 3 in a double layer, which not only saves manpower but also improves the paper winding efficiency of the paper winding machine.
