Problems solved by technology

[0008] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an improved antistatic film winding device, which effectively solves the problem that the film is attached to the empty reel when the antistatic film is produced. Good, it is easy to appear that it is not attached to the empty reel, resulting in traction film rupture, production shutdown, and serious losses

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] Referring to the accompanying drawings, the present invention includes an up and down position adjustment mechanism. The up and down position adjustment mechanism is fixed with a cover plate 6 through an L-shaped connecting block 4. The fastening knob 7 is fixed, the top of the telescopic plate 8 is fixed with a positioning plate 12 by bolts, and one side of the positioning plate 12 is equidistantly embedded with blowing nozzles 11, and the blowing nozzles 11 are respectively connected with the main air pipe 9 through the bronchus 10, One side of the main air pipe 9 is connected with the air outlet of the air compressor 14 through a connecting hose 13 . Electromagnetic valve 15 is housed on the pipeline that connects hose 13. The voltage sensor is used to detect whether the electrostatic adsorption rod is powered, and sends the signal to the input ter...

Abstract

The invention relates to an antistatic film winding method and its device. The method uses a film winding device, a winding turret is arranged in the film winding device, and two winding steel pipes are fixed at intervals on the winding turret. shaft, near the position of the winding steel shaft, the electrostatic adsorption rod and the cutter are arranged in sequence. After the improvement, an air blowing mechanism is added in the winding device. In an instant, the film leader is immediately blown to the empty reel, avoiding the poor adsorption of the film leader due to the conductive characteristics of the product itself, which not only effectively ensures the success rate of automatic roll change, but also improves production efficiency.

Description

technical field [0001] The invention relates to the field of film technology, in particular to a film winding device. Background technique [0002] Polyester film is widely used in various fields due to its good mechanical properties, thermal properties and chemical inertness. Biaxial stretching method is the main production method of polyester film. [0003] In the production process of biaxially oriented polyester film, the winding process is a key link. [0004] Among the film products, anti-static film products have relatively good electrical conductivity, so that during the automatic roll changing process of the winding device, the automatic roll changing cannot be performed stably on the winding device due to the poor effect of high-voltage electrostatic adsorption. [0005] The main function of the winding device is to wind the wide-width film after two-way stretching on the steel shaft, which is convenient for later cutting and use. Due to the high speed, the rewi...
