[0041] Among them, the motor one 102 and the motor two 222 are existing devices, and wires, switches and power interfaces are additionally provided, which are not the main technical features and will not be described here.
[0042] Among them, the electrostatic generator 228 is an existing device, which is composed of a high-voltage power supply, a control circuit and a discharge electrode, which is not the main technical feature and will not be described here.
[0043] The upper 2-10 cm of the winding roller 103 is fixedly provided with an electrostatic eliminator to avoid the adverse effects of wrinkles on the plastic film caused by static electricity. The electrostatic eliminator is not the main technical structure and will not be described here.
[0044] The operator first removes the threaded column 202 from the side of the unwinding roller 101 and the winding roller 103 by rotating the threaded column 202, and then places the middle of the plastic film sleeve that needs to be corrected on the unwinding roller 101 and the collection sleeve on the outside of the winding roller 103. Then, the operator fixes the sleeve by rotating the threaded column 202, and then pulls out one end of the plastic film from the top of the correction plate 204 and into the inside of the flattening roller 230, and then fixes the sleeve on the outside of the winding roller 103 through the middle of the flattening roller 230.
[0045] Then the operator manually rotates the rotating handle 207 on one side of the fixed block 205. Through the rotation of the rotating handle 207, the cone gear set 208 transmits power to the I-beam 210, and the I-beam 210 starts to rotate with the ball screw 211. Through the rotation of the ball screw 211, the sliding nut 212 starts to slide in the square groove 209. Through the sliding of the sliding nut 212, the static generator 228 slowly approaches the plastic film on the surface of the correction plate 204, until the plastic film is in contact with the inclined surface of the correction plate 204. At this time, the operator can determine the position of the plastic film that needs to be corrected according to the amount of plastic film on both sides of the correction plate 204.
[0046] Then connect the motor 102 and the motor 222 to the power supply interface through the wires. Then, the operator manually squeezes the two C-shaped blocks 217. Through the approach of the two C-shaped blocks 217, the spring 220 starts to contract, and the sliding block 219 starts to slide in the square groove 218. The bottom of the two C-shaped blocks 217 slides out of the auxiliary groove 221 in the middle of the fixed plate 213. Then, the operator slides the I-beam 215 in the opposite direction of the plastic film offset according to the offset direction of the plastic film. When the I-beam 215 slides to the leftmost or rightmost side of the fixed plate 213, the operator can release the two C-shaped blocks 217. At this time, the spring 220 inserts the bottom of the C-shaped block 217 into the inside of the auxiliary groove 221 to fix the I-beam 215. At this time, the bevel gear 223 and the bevel gear 227 are engaged.
[0047] When the bevel gear 223 is engaged with the bevel gear 227, the operator energizes the electrostatic generator 228 on the side engaged with the bevel gear 223, at which time the high-voltage power module inside the electrostatic generator 228 converts the input lower voltage into high-voltage output, then forms an electric field through the discharge electrode to generate electrostatic discharge, and finally makes the electrostatic stable inside the electrode ring 229 through the control circuit, at which time the electrode ring 229 adsorbs the plastic film, then the operator starts the motor 102 and the motor 222 through the switch, at which time the plastic film starts to be wound through the rotation of the winding roller 103, and at the same time, the operator adjusts the rotation speed of the motor 222 according to the deviation of the plastic film on the surface of the deviation plate 204, at which time the plastic film can be deviated.
[0048] When the plastic film is wound on the winding roller 103, at this time the electrostatic eliminator on the top of the winding roller 103 is started, and the air around is ionized by the high-voltage power inside the electrostatic eliminator to generate a large number of positive and negative ions, change the charge distribution on the surface of the plastic film, make the charge tend to be balanced, thereby reducing static electricity, and achieving the purpose of neutralizing static electricity.
[0049] The implementation principle of the plastic film deviation correcting device is as follows: the operator fixes the sleeves outside the unwinding roller 101 and the winding roller 103 by rotating the threaded column 202, then manually passes one end of the plastic film from the surface of the deviation plate 204, then passes through the flattening roller 230, and finally fixes it on the sleeve outside the winding roller 103, after completion, the operator rotates the rotating handle 207, the bevel gear set 208 rotates with the ball screw 211 through the work-shaped column 210, the sliding nut 212 starts to slide inside the square groove one 209 through the rotation of the ball screw 211, and the plastic film is attached to the surface of the deviation plate 204, so as to judge the deviation of the plastic film.
[0050] Then the spring 220 is contracted by extruding the two C-shaped blocks 217, the sliding block 219 starts to slide inside the square groove two 218, the bottom of the C-shaped block 217 slides out of the auxiliary groove 221, then the operator makes the work-shaped block 215 slide in the opposite direction of the deviation direction of the plastic film, and when the work-shaped block 215 slides to the leftmost or rightmost side of the fixed plate 213, the operator can fix the work-shaped block 215, at which time the bevel gear 223 is engaged with the bevel gear 227, then the operator energizes the electrostatic generator 228 on the side engaged with the bevel gear 223 to make the electrode ring 229 adsorb the plastic film, then starts the motor 102 and the motor 222 through the switch, and at the same time, the operator adjusts the rotation speed of the motor 222 according to the deviation of the plastic film, so as to correct the deviation of the plastic film.
[0051] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered in the protection scope of the present application.
