Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of PET sheet production equipment, and in particular to an antistatic device for a PET production line. Background Technology
[0002] During the production of PET sheets, friction and separation between the sheets and equipment generate a large amount of static electricity. If the static electricity cannot be effectively eliminated, the surface of the sheet will attract dust, core debris and other impurities from the air during winding, resulting in stains and foreign objects on the product surface, which seriously affects product quality.
[0003] Currently, most PET production lines use electrostatic ropes at the traction roller position for static electricity removal. However, electrostatic ropes are passive static removal devices, which can only release some static electricity through contact conduction and cannot actively neutralize the static charge on the sheet surface, resulting in low static removal efficiency. Furthermore, existing electrostatic ropes are usually only placed in front of the traction roller and below the sheet, which can only perform limited static removal on the lower surface of the sheet. The upper surface of the sheet and the new static electricity generated after passing through the traction roller cannot be effectively eliminated, resulting in a large amount of static electricity remaining on the sheet when it enters the winding machine. Utility Model Content

[0022] Working Principle: When using this invention, the ion high-voltage generator 12 on the frame 1 powers the static eliminator 2. Two sets of static eliminators 2 are used to eliminate static electricity from the PET sheet passing through the traction roller 11. One set of static eliminators 2 is used to eliminate static electricity from the lower surface of the input PET sheet, and the other set is used to eliminate static electricity from the upper surface of the output PET sheet. The static eliminator 2 transmits current to the plug 24 via a high-voltage wire, then into the busbar 25, and finally to the emitting needle 26. The emitting needle 26 generates positive and negative ions by ionizing the air with high voltage, actively neutralizing the static charge on the surface of the PET sheet. Multiple static eliminators 2 can be connected in series to the output of the ion high-voltage generator 12, that is, the plugs 24 of adjacent static eliminators 2 are connected via high-voltage wires with a spring structure. Since the static eliminator 2 is assembled using connecting components 3, its length can be adjusted according to actual working conditions. Specifically, turning the knob 32 drives the threaded rod 31, and the threaded rod 31... The sleeve 33 rotates within the through hole 313, and is limited by the screw 35. The rotating threaded rod 31 drives the first connecting block 36 through the threaded hole 38. Under the guidance of the first guide sleeve 39 and the second guide sleeve 310, the first connecting block 36 moves downward, so that the first limiting block 37 is no longer tightly pressed against the inner wall of the slide groove 22. At this time, the position of the adjustable housing 21 can be slidably adjusted to realize the overall length adjustment of the assembled antistatic assembly 2. After the adjustment is completed, the knob 32 is turned in the opposite direction, so that the first connecting block 36 moves upward. After repositioning, the first limiting block 37 presses tightly against the inner wall of the slide groove 22 again, thus locking the housing 21. The bracket 13 is used to connect the end of the assembled antistatic component 2 and the frame 1. The stop block 23 is used to limit the sliding of the connecting component 3 in the slide groove 22. The internal thread 34 is used to realize the threaded connection between the screw 35 and the sleeve 33. The second connecting block 311 is used to support the second limiting block 312. The second limiting block 312 is used to cooperate with the first connecting block 36 to lock the connecting component 3 in the slide groove 22.
