[0033] See also Figures 1 to 6 The utility model provides a technical solution: a composite coil cutting device, comprising a base 1, a rotating groove 11 is provided on the base 1, and the front part of the base 1 is a box structure; a guide roller assembly 2, the guide roller assembly 2 comprises a first guide roller 21 and a second guide roller 22, the second guide roller 22 is located above the first guide roller 21, and is lifted and lowered in the vertical direction by a lifting mechanism 23; a winding assembly 3, the winding assembly 3 comprises two support plates 31 distributed at a relative interval, and the support plates 31 are fixedly arranged on the top surface of the base 1; a pressing and cutting assembly 4, the pressing and cutting assembly 4 comprises a fixed plate 41, a fixed plate 42, a fixed plate 43, a fixed plate 44, a fixed plate 45, a fixed plate 46, a fixed plate 47, a fixed plate 48, a fixed plate 49, a fixed plate 41, a fixed plate 41, a fixed plate 42, a fixed plate 44, a fixed plate 46, a fixed plate 48, a fixed plate 49, a fixed plate 41, a fixed plate 42, a fixed plate 43, a fixed plate 44, a fixed plate 46, a fixed plate 48, a fixed plate 49 ... The plate 41 is fixed on the front side of the support plate 31, and two relatively spaced through grooves 42 are provided on the fixed plate 41. Two relatively spaced electric telescopic rods 43 are fixed on the fixed plate 41. The output end of the electric telescopic rod 43 is fixedly connected to the movable plate 44. The movable plate 44 moves inside the through groove 42 through the electric telescopic rod 43. A pressing wheel 45 is fixed on the bottom surface of the movable plate 44. An L-shaped fixed plate 46 is fixed on the front side of the movable plate 44. The L-shaped fixed plate 46 is slidably connected to the fixed plate 41, and a cutting knife 47 is provided on the bottom surface of the L-shaped fixed plate 46.

[0034] In this embodiment, the motor 231 is first started to reverse, so that the second guide roller 22 is away from the first guide roller 21, and then the front end of the composite coil is cut to a suitable size on both sides as required, and then the cut end is passed through the gap between the first guide roller 21 and the second guide roller 22, and then the composite coil is first passed through the cutting knife 47, and then passed under the edge pressing wheel 45, and then the composite coil is connected to the winding roller 33, and then the motor 231 is started to rotate forward to drive the second guide roller 22 to move toward the first guide roller The roller 21 moves, and the motor 231 rotates forward to drive the first bevel gear 232 to rotate forward. The first bevel gear 232 rotates forward to drive the two bevel gears meshing with it to rotate, thereby driving the transmission shaft 233 to rotate. Because the bevel gear at the bottom of the screw 235 meshes with the bevel gear at one end of the transmission shaft 233, the rotation of the transmission shaft 233 drives the screw 235 to rotate forward. The screw 235 is rotatably connected to the box wall and the base 1 of the lifting box 236, and the screw 235 is screwed to the lifting block 221, so the screw 235 The positive rotation drives the lifting block 221 to move downward so that the first guide roller 21 and the second guide roller 22 are close to clamp the composite coil, and vice versa, the motor 231 reverses to move the second guide roller 22 away from the first guide roller 21; then the winding motor 32 is started, and the winding motor 32 drives the winding roller 33 to rotate to realize the winding of the composite coil. At the same time, the cutting knife 47 trims the composite coil, and at this time, the bottom surface of the cutting knife 47 is lower than the bottom surface of the pressing wheel 45, ensuring that the edge of the cut composite coil can pass through the pressing wheel When the composite coil passes between the first guide roller 21 and the second guide roller 22, the composite coil will be flattened by the rolling force of the first guide roller 21 and the second guide roller 22 when rolling against each other, so as to prevent indentations when the composite coil is wound; and because the bottom surface of the edge pressing wheel 45 is lower than the height of the central axis of the winding roller 33, the edge of the composite coil will pass through the rolling edge pressing of the edge pressing wheel 45 during the winding process, and the edge pressing wheel 45 will further flatten the edge of the composite coil to prevent warping;

[0035] The gap distance between the second guide roller 22 and the first guide roller 21 can be adjusted by the forward and reverse rotation of the motor 231, and the adjustment of the gap distance can meet the guiding requirements of composite coils of different thicknesses;

[0036] Among them, the electric telescopic rod 43 is started. Since the output end of the electric telescopic rod 43 is fixedly connected to the moving plate 44, the bottom surface of the moving plate 44 is fixedly connected to the pressing wheel 45, and at the same time, an L-shaped fixed plate 46 is provided on the front side of the moving plate 44, and a cutting knife 47 is provided under the L-shaped fixed plate 46, the distance between the two pressing wheels 45 can be adjusted by extending and retracting the two relatively spaced electric telescopic rods 43, and the distance between the two cutting knives 47 can also be adjusted, so as to meet the pressing and cutting requirements of composite coils of different widths.

[0037] For further information, see Figure 1 and Figure 2The first guide roller 21 is accommodated in the rotating groove 11 and is connected to the inner wall of the rotating groove 11 through the first rotating shaft 211. The first rotating shaft 211 is rotatably connected to the inner wall of the rotating groove 11.

[0038] In this embodiment, the first rotating shaft 211 is rotatably connected to the inner wall of the rotating groove 11, and the first rotating shaft 211 is fixedly connected to the first guide roller 21. When the winding roller 33 rotates to drive the composite coil to be wound, the first guide roller 21 will rotate in the rotating groove 11.

[0039] In another embodiment, the first rotating shaft 211 is fixedly connected to the inner wall of the rotating groove 11 , and the first rotating shaft 211 is fixedly connected to the first guide roller 21 . When the winding roller 33 rotates to drive the composite coil to be wound, the first guide roller 21 will also rotate in the rotating groove 11 .

[0040] For further information, see Figure 2 The lifting mechanism 23 includes a motor 231, which is fixed on the bottom surface of the inner wall of the base 1. The output end of the motor 231 is fixedly connected to the first bevel gear 232. Two relatively spaced transmission shafts 233 are provided above the motor 231. Bevel gears are fixed at both ends of the transmission shaft 233. The bevel gear at one end of the transmission shaft 233 is meshed with the first bevel gear 232.

[0041] For further information, see Figure 2 The lifting mechanism 23 also includes two lifting boxes 236 that are relatively spaced apart. Both sides of the lifting boxes 236 are open structures. The two lifting boxes 236 are fixed on the top surface of the base 1 and are distributed on both sides of the rotating groove 11. A screw 235 is provided inside the lifting box 236. A helical gear is provided on the bottom surface of the screw 235 and is meshed with the helical gear at the other end of the transmission shaft 233.

[0042] In this embodiment, when the motor 231 reverses and drives the first bevel gear 232 to reverse, the first bevel gear 232 reverses and drives the bevel gear at one end of the transmission shaft 233 meshing therewith to rotate, thereby driving the transmission shaft 233 to rotate, and also driving the bevel gear at the other end of the transmission shaft 233 to rotate. The rotation of the bevel gear at the other end of the transmission shaft 233 drives the bevel gear at the bottom end of the screw 235 to rotate, thereby driving the screw 235 to reverse in the lifting box 236. At this time, the lifting block 221 rises, thereby driving the second guide roller 22 away from the first guide roller 21; conversely, when the motor 231 rotates forward and drives the second guide roller 22 to approach the first guide roller 21, the gap between the second guide roller 22 and the first guide roller 21 is changed by the forward and reverse rotation of the motor 231. The change of the gap between the second guide roller 22 and the first guide roller 21 can meet the guiding requirements of composite coils of different thicknesses; a protection box is provided on the outside of each meshing bevel gear, which can not only limit the relative position of the meshing bevel gears, but also protect the bevel gears.

[0043] For further information, see Figure 2 and Figure 3 A lifting block 221 is provided on the outer wall of the screw rod 235 . The lifting block 221 is located in the inner space of the lifting box 236 . The lifting block 221 is slidably connected to the inner wall of the lifting box 236 . A second rotating shaft 222 is provided on the outer side of the lifting block 221 . The second guide roller 22 is connected to the lifting block 221 via the second rotating shaft 222 .

[0044] In this embodiment, when the screw 235 rotates, since the screw 235 is threadedly connected to the lifting block 221 and is constrained by the lifting box 236, the lifting block 221 will rise and fall along the screw 235, thereby driving the second rotating shaft 222 and the second guide roller 22 to rise and fall, thereby adjusting the gap between the second guide roller 22 and the first guide roller 21.

[0045] For further information, see Figure 2 A fixing frame 234 is provided on the outer wall of the transmission shaft 233 . The fixing frame 234 is fixedly connected to the bottom surface of the inner wall of the base 1 and is rotatably connected to the transmission shaft 233 .

[0046] In this embodiment, when the transmission shaft 233 rotates, the fixing frame 234 supports the transmission shaft 233, so that the helical gear at the bottom end of the screw rod 235 and the helical gear at the other end of the transmission shaft 233 always remain in meshing state without affecting the overall transmission.

[0047] The working principle and use process of the utility model are as follows: first, the motor 231 is started to rotate in reverse, so that the second guide roller 22 is away from the first guide roller 21, and then the front end of the composite coil is cut to a suitable size on both sides according to the requirements, and then the cut end is passed through the gap between the first guide roller 21 and the second guide roller 22, and then the composite coil is first passed through the cutting knife 47, and then passed under the edge pressing wheel 45, and then the composite coil is connected to the winding roller 33, and then the motor 231 is started to rotate forward to drive the second guide roller 2 2 moves toward the first guide roller 21. At this time, the motor 231 rotates forward to drive the first bevel gear 232 to rotate forward. The first bevel gear 232 rotates forward to drive the two bevel gears meshing with it above to rotate, thereby driving the transmission shaft 233 to rotate. Because the bevel gear at the bottom of the screw rod 235 meshes with the bevel gear at one end of the transmission shaft 233, the rotation of the transmission shaft 233 drives the screw rod 235 to rotate forward. The screw rod 235 is rotatably connected to the box wall and the base 1 of the lifting box 236. The screw rod 235 is screwed to the lifting block 221, so the screw rod 235 is connected to the lifting block 221. The rod 235 rotates forward to drive the lifting block 221 to move downward so that the first guide roller 21 and the second guide roller 22 are close to clamp the composite coil, and vice versa, the motor 231 rotates in the reverse direction to move the second guide roller 22 away from the first guide roller 21; then the winding motor 32 is started, and the winding motor 32 drives the winding roller 33 to rotate to realize the winding of the composite coil, and at the same time, the cutting knife 47 trims the composite coil, and at this time, the bottom surface of the cutting knife 47 is lower than the bottom surface of the pressing wheel 45, to ensure that the edge of the cut composite coil can pass through the pressing wheel 45 The edge pressing of the edge wheel 45; when the composite coil passes between the first guide roller 21 and the second guide roller 22, the rolling force between the first guide roller 21 and the second guide roller 22 will flatten the composite coil, thereby preventing indentations when the composite coil is wound; and because the bottom surface of the edge pressing wheel 45 is lower than the height of the center axis of the winding roller 33, the edge of the composite coil will pass through the rolling edge pressing of the edge pressing wheel 45 during the winding process, and the edge pressing wheel 45 will further flatten the edge of the composite coil to prevent warping.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
