Specific implementation

[0029] As Figures 1-6 shown, a kind of plastic film winding device, comprising:

[0030] A base 101 has two opposing columns 102 on its top. Two docking components are also provided, each mounted on the upper part of a corresponding column 102. One docking component has a motor 202. A winding shaft 3 is connected between the two docking components. Each docking component includes a rotating shaft 201 rotatably mounted on the upper part of the column 102. One end of the rotating shaft 201 has the motor 202, which drives the rotating shaft 201 to rotate. Two side stops 203 are oppositely arranged on the circumference of the inner end of the rotating shaft 201 on the column 102, which axially limit the plastic film during winding. The inner end of the rotating shaft 201 on the column 102 has polygonal holes 2. 04. A polygonal post 206 is fitted inside the polygonal hole 204. A toggle rod 207 is provided around the polygonal post 206. A limit hole 205 is provided around the rotating shaft 201. The limit hole 205 communicates with the polygonal hole 204. The toggle rod 207 is located inside the limit hole 205. A spring 208 is provided between one end of the polygonal post 206 and the bottom of the polygonal hole 204. The spring 208 can push one end of the polygonal post 206 out of the polygonal hole 204. The toggle rod 207 can easily push the polygonal post 206 into the polygonal hole 204. The combination of the toggle rod 207 and the limit hole 205 can also axially limit the polygonal post 206, preventing the polygonal post 206 from completely coming out of the polygonal hole 204 under the action of the spring 208.

[0031] Both ends of the take-up shaft 3 are provided with polygonal fastening holes. The polygonal fastening holes at both ends of the take-up shaft 3 are respectively locked onto the corresponding polygonal posts 206. In use, by moving the lever 207, the polygonal posts 206 are moved into the polygonal holes 204, causing the spring 208 to contract and the polygonal posts 206 to be completely retracted into the polygonal holes 204. At this time, the take-up shaft 3 can be placed between the two rotating shafts 201. Then, the lever 207 is released, causing the spring 208 to rebound and push against the polygonal posts 206, so that one end of the polygonal posts 206 moves out of the polygonal holes 204 and is locked into the polygonal fastening hole at the end of the take-up shaft 3, thereby realizing the fastening of the take-up shaft 3 between the two rotating shafts 201.

[0032] When the motor 202 starts and drives the corresponding rotating shaft 201 to rotate, it can drive the take-up shaft 3 to rotate. One end of the plastic film is attached to the outer periphery of the take-up shaft 3. At this time, during the rotation of the take-up shaft 3, the plastic film can be continuously wound onto the take-up shaft 3.

[0033] The resisting member is provided with two resisting members arranged on the top of the base 101, and the two resisting members are arranged in an "eight" shape. The resisting member comprises a bottom plate 401 arranged on the top of the base 101, and a stabilizing cylinder 402 is arranged on the top of each end of the bottom plate 401. A resisting rod 403 and a supporting spring 404 are arranged in each stabilizing cylinder 402. The supporting spring 404 is located between the bottom end of the resisting rod 403 and the inner bottom of the stabilizing cylinder 402. A resisting roller 405 is rotatably arranged between the top of the two resisting rods 403. The supporting spring 404 can resist and support the resisting rod 403, so that the resisting rod 403 can move obliquely upward, and the resisting roller 405 can resist the bottom of the circumferential wall of the winding shaft 3.

[0034] The cutting member is arranged on the upper part of the resisting member on the side where the plastic film is fed in. The cutting member comprises an assembly plate 501 arranged between the upper parts of the two resisting rods 403 in the resisting member on the side where the plastic film is fed in. A through hole 502 is transversely arranged in the interior of the assembly plate 501. A cutting groove 503 is arranged at the bottom of the through hole 502. A clamping hole 504 is arranged at the top of the through hole 502. A cutting plate knife 505 is clamped in the clamping hole 504. A stabilizing column 506 is arranged at the top of the assembly plate 501. The side plate at the top of the cutting plate knife 505 is sleeved on the stabilizing column 506. A reset spring 507 is arranged on the stabilizing column 506 between the top of the assembly plate 501 and the bottom surface of the side plate at the top of the cutting plate knife 505. The bottom of the cutting plate knife 505 is retracted in the clamping hole 504 under the action of the reset spring 507, so that the cutting edge at the bottom of the cutting plate knife 505 is prevented from being exposed in the through hole 502.

[0035] When the plastic film is wound, the plastic film is passed through the through hole 502, and then the feeding end of the plastic film is adhered to the circumferential wall of the winding shaft 3. The corresponding rotating shaft 201 is driven to rotate under the action of the started motor 202, so that the winding shaft 3 is driven to rotate. The plastic film can be continuously wound on the winding shaft 3 in the process of rotation. In the process of winding, the resisting roller 405 is resisted on both sides of the bottom of the plastic film wound on the winding shaft 3 under the resisting action of the supporting spring 404, so that the plastic film wound on the winding shaft 3 is compressed, and the phenomenon that the plastic film wound on the winding shaft 3 is loose is avoided. When the plastic film is wound in place, the top of the cutting plate knife 505 is pressed, so that the reset spring 507 is retracted, and the cutting edge at the bottom of the cutting plate knife 505 is moved downward from the clamping hole 504 and cut into the cutting groove 503. In the process of cutting into the cutting groove 503, the cutting plate knife 505 can cut the plastic film fed in and the plastic film on the winding shaft 3, so that the winding work of the plastic film is completed.
