Description

Technical Field

[0001] The utility model relates to the field of film processing, in particular to a balanced roller type coating device for film processing. Background Art

[0002] In the film processing process, coating operation is a crucial link. The uniformity and accuracy of coating directly affect the quality and performance of the product.

[0003] However, traditional coating devices often have problems such as uneven coating thickness and low coating efficiency during the coating process.

[0004] In order to solve the problem of uneven coating thickness, most of the coating rollers on the market are equipped with an auxiliary roller on one side of the coating roller. By applying force on both sides of the auxiliary roller, the auxiliary roller is brought closer to the coating roller. However, this method of applying pressure can easily cause the middle part of the auxiliary roller to not fit the coating roller, resulting in reduced efficiency of the thin film coating process. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the utility model provides a technical solution that can solve the above-mentioned problems.

[0006] A balanced roller coating device for film processing comprises a support frame;

[0007] A feeding roller is rotatably arranged on one side of the support frame, and a coating roller is rotatably arranged in the feeding direction of the feeding roller;

[0008] An auxiliary roller is rotatably arranged on one side of the coating roller away from the feeding roller, and the auxiliary roller contacts the coating roller and slides with the support frame;

[0009] A balancing roller is rotatably arranged on one side of the auxiliary roller away from the feed roller, and the balancing roller is arranged in the middle of the auxiliary roller and in contact with the auxiliary roller;

[0010] Electric telescopic rods are respectively arranged at both ends of the balancing roller shaft, and a first rotating block is respectively arranged on the telescopic end of each electric telescopic rod, and the two ends of the balancing roller shaft are respectively rotatably matched with the first rotating blocks.

[0011] As a further solution of the utility model: the outer surface of the auxiliary roller is provided with a soft rubber layer.

[0012] As a further solution of the utility model: a pressing roller is rotatably arranged between the auxiliary roller and the balancing roller, and is in contact with the auxiliary roller and the balancing roller respectively.

[0013] As a further solution of the utility model: the length of the pressing roller is not less than the length of the auxiliary roller.

[0014] As a further solution of the utility model: second rotating blocks are rotatably provided at both ends of the auxiliary roller and the pressing roller, and sliding grooves are provided on both sides of the support frame corresponding to the second rotating blocks.

[0015] Compared with the prior art, the beneficial effect of the utility model is that an auxiliary roller is provided on one side of the coating roller, and a balancing roller is provided in the middle of the other side of the auxiliary roller. The balancing roller is driven by an electric telescopic rod to apply a force to the middle of the auxiliary roller, driving it to move to one side of the coating roller, so that it can better contact with the coating roller, thereby ensuring that the film can be evenly coated on the coating roller, and effectively improving work efficiency.
