Description

Technical Field

[0001] The utility model belongs to the technical field of coating equipment, and in particular relates to a coating mechanism for protecting the surface of alloy steel. Background Art

[0002] Laminating refers to the process of applying a transparent plastic film to the surface of the workpiece to be processed through hot pressing. When processing alloy steel plate castings, the plastic film is sometimes pressed onto the steel plate at high temperature through a laminating device to form a laminated steel plate. The laminated alloy steel plate has good corrosion resistance and wear resistance. At the same time, the laminated steel plate has a smooth appearance, beautiful surface, and strong pressure resistance. When the existing laminating device is in use, multiple steel plates are generally continuously conveyed through a conveying mechanism, and then the film is hot-melted and rolled onto the steel plate through a hot pressing roller. The plastic film is generally in a roll shape, so after the lamination of a steel plate is completed, the film needs to be cut to separate the steel plates from each other. However, when cutting the film, in order to enable the cutting structure to cut the film between the two steel plates more accurately, the conveying mechanism of the steel plate is generally stopped during cutting, resulting in frequent pauses in the processing, which is not conducive to the processing.

[0003] To this end, a coating device for alloy steel casting processing, with the announcement number "CN116061449B," includes a coating module, which is provided with a cutting module. The cutting module includes a connecting box, with connecting frames provided on both sides of the connecting box. A sliding plate is slidably connected to the inner side of the connecting box. Two return springs 2 are fixedly connected to the top surface of the sliding plate and fixedly connected to the top surface of the sliding plate. Roller rods 1 and 2 are provided at the bottom of the sliding plate. After the coated steel plate passes through the bottom of roller rods 1 and 2, roller rods 1 and 2 are inserted between the two steel plates, causing the cutting blade to move downward to cut the film. The steel plate can push the sliding plate to move, allowing the cutting blade to follow the movement of the steel plate. This allows the cutting blade to accurately cut between the two steel plates without stopping the conveyance of the steel plates, which is conducive to continuous coating of the steel plates.

[0004] However, for the above-mentioned coating device for alloy steel casting processing, although the steel plate is placed on the roller conveyor, the steel plate is conveyed by the roller conveyor, the film roll is put on the reel, and the film is pulled out to make the plastic film stick to the steel plate, there are still the following obvious defects during use: the above-mentioned coating device can only perform single-sided coating operation on the alloy steel plate at a time. Since there is no corresponding mechanism for simultaneous coating on both sides, it is impossible to achieve two simultaneous coating operations on the alloy steel plate. Therefore, manual labor or equipment is required to coat the other side of the alloy steel plate during transportation, which will affect the progress of the coating work of the alloy steel plate.

The vertical upper end of the fixed lower conveyor line 2 is correspondingly provided with a movable upper film pressing conveyor line 3 for pressing and fitting the film on the alloy steel. The movable upper film pressing conveyor line 3 is pushed downward by the film pressing cylinder 10 so that the conveying rollers arranged rolling on the inner side can press the film.
