Problems solved by technology

[0004] 1. The control precision is low. When the deviation correction roller moves, it directly drives the film belt wound on the deviation correction roller to move, which is basically 1:1 deviation correction. When the deviation correction range is small, the deviation correction roller moves very easily. After the deviation correction is in place, it needs to be corrected in reverse. In the same way, excessive correction is also prone to occur during correction, so that the correction roller is always in a dynamic adjustment state of moving back and forth, and precise control cannot be achieved
[0005] 2. The frequent back and forth movement of the rectifying roller will cause the following vibration of the whole equipment, which will affect the smoothness of slurry scraping and coating, which will easily lead to uneven film thickness and poor stability
[0006] 3. The method of correcting the deviation of the film belt through the movement of the deviation correction roller cannot balance the tightness on both sides of the film belt. After the film belt is wound into a film roll, the uniformity of the tightness at both ends of the film roll is poor. During the subsequent unwinding process, It is necessary to continue to correct the deviation and treat the symptoms but not the root cause

Embodiment 1

[0031] Such as Figures 1 to 4 As shown, the winding mechanism of the perfluorinated ion exchange membrane casting machine provided by the present invention includes: frame 10, driving roller 20, tension roller 30, winding roller 40, deviation correction assembly 50, wherein, frame 10 consists of two A vertical plate 16 arranged in parallel and a plurality of connecting rods 17 connected between the two vertical plates 16 constitute a driving roller 20, a tension roller 30 and a winding roller 40 which are sequentially and rotatably arranged on the frame 10 along the front-rear direction. On, the axis of rotation of driving roller 20, tension roller 30, winding roller 40 is parallel to the horizontal plane; Some rollers 18 are also arranged between driving roller 20 and winding roller 40, and the axis of rotation of roller 18 is parallel to the horizontal plane. On the horizontal plane; the deviation correction assembly 50 is arranged between the tension roller 30 and the wind...

Embodiment 2

[0036] Embodiment two is basically the same as embodiment one, the difference is that, as Figure 5 As shown, a number of radial holes 524 are also provided on the correction roller 52, and the radial holes 524 pass through the rubber ring 523 and / or the roller body 521, and pass through the inner cavity 525 of the correction roller 52 and the air pipe connected to the end of the correction roller 52. 526 communicates, and the air pipe 526 is used to provide positive pressure or negative pressure to the radial hole 524 to adjust the friction between the film belt and the correction roller 52 .

[0037] In this embodiment, the pressure provided by the gas pipe 526 is related to the detection value of the deviation correction sensor 53. Specifically, the allowable deviation value of the side of the film tape is ±0.3mm, and the deviation value of the side edge of the film tape is detected by the deviation correction sensor 53. When it exceeds this range, the deviation correction ...

Abstract

The winding mechanism of the perfluorinated ion exchange membrane casting machine comprises a machine frame, a driving roller, a tension roller, a deviation rectifying assembly and a winding roller, the driving roller, the tension roller, the deviation rectifying assembly and the winding roller are sequentially arranged on the machine frame in the front-back direction, and the deviation rectifying assembly comprises a deviation rectifying support, a deviation rectifying roller rotationally arranged on the deviation rectifying support and a deviation rectifying sensor. The deviation rectifying support is rotationally connected with the rack through the push rod motor, the deviation rectifying roller can be driven to deflect through rotation of the deviation rectifying support, a film belt moves in the axial direction of the deviation rectifying roller, deviation rectifying is achieved, and due to the fact that the movement distance is enlarged by the deflection angle, accurate control can be achieved, and stability is improved; the deviation rectifying roller comprises the rigid roller body and the rubber rings embedded in the annular grooves in the roller body, the outer circumferential faces of the rubber rings and the roller body are flush, the rubber rings can be used for preventing the film belt from moving on the deviation rectifying roller, part of energy for driving the film belt to move is converted to the film belt, the two sides of the film belt deform, and the deviation rectifying effect is improved. Therefore, the tightness of two sides of the membrane belt is balanced.

Description

technical field [0001] The invention relates to the technical field of casting machines, in particular to a winding mechanism of a perfluorinated ion exchange membrane casting machine. Background technique [0002] In industries such as water electrolysis hydrogen production, fuel cells, and chlor-alkali electrolysis, most of the membranes used for ion exchange are perfluorinated ion exchange membranes. The batch continuous production method of this product mainly adopts the casting method, which is obtained by using The slurry flows down from the hopper, is scraped and coated on the base belt with a certain thickness, and is peeled off after drying and curing to form a strip-shaped film product. It has the advantages of low cost, high quality, and simple production process. It is widely used and used. Casting production requires the use of a casting machine. [0003] The winding mechanism of the casting machine is one of the important parts of the casting machine. The wind...
