Problems solved by technology

In the actual film coating process, due to reasons such as the sagging of the substrate, it is necessary to increase the tension of the coating section to flatten the film to avoid missing coating. At the same time, the tension of the film in the oven area is also increased. However, the substrate is easy to shrink under drying and heating. When the longitudinal tension is large, longitudinal stretching and transverse shrinkage will occur. If When the processing speed is greater than 20 m / s, the product quality will be seriously affected, so the production efficiency of traditional coating machines is low

Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the embodiments and with reference to the accompanying drawings.

[0019] For the pressure roller device of a coating machine winding mechanism in this embodiment, please refer to the Figure 1 to Figure 3 , including a tension adjustment roller 8 fixed on the frame 2, one side of the tension adjustment roller 8 is pressed against a pressure roller, and the tension adjustment roller 8 goes around the base material 5 that exceeds half a circle of the tension adjustment roller 8, so After the substrate 5 is transferred to the coating structure, it is coated into a coating film 7 and is transferred to the oven by the vacuum adsorption roller 1; the tension adjustment roller 8 and the vacuum adsorption roller 1 are both driving rollers.

[0020] After the substrate 5 of this device bypasses the tension adjustment roller 8, a "tension cutoff" is formed. After the substrate 5 coated in the coa...

Abstract

The invention discloses a compression roller device of a winding mechanism of a coating machine. The compression roller device comprises a tension adjusting roller fixed to a rack, wherein a compression roller abuts against one side of the tension adjusting roller; a base material winds round the tension adjusting roller for more than half a circle of the tension adjusting roller; and the base material is driven by a vacuum absorption roller to a dryer after being driven to a coating structure. The compression roller device of the winding mechanism of the coating machine has the advantage that the quality of products is not affected when the machining speed is increased.

Description

technical field [0001] The invention relates to the field of coating, in particular to a pressure roller device of a winding mechanism of a coating machine that does not affect product quality when the processing speed is increased. Background technique [0002] With the expansion of social demand for isolation films, high-speed and high-precision film coating machines have become the expectation of the whole industry and even the whole society. The main research direction in improving the surface properties of the film is film coating treatment, that is, coating a layer of material on the surface of the film. After film coating, it can effectively improve the high temperature resistance, safety and thermal stability of the film and improve the mechanical properties of the film. Strength, thereby prolonging the battery cycle life. To sum up, in the lithium battery production line, the film coating machine is the most critical equipment, and customers are increasingly demand...
