Description

Technical Field

[0001] The utility model belongs to the technical field of coating processing, in particular to an automatic coating device for a heat insulation sheet. Background Art

[0002] The coating function is to transfer the coating in the rubber groove to the main pressure roller, and the main pressure roller then coats the coating on the surface of the insulation sheet material to achieve the transfer and coating of the coating, which can ensure that the surface adhesive layer of the insulation sheet is uniform and stable. The coating function is mainly achieved by the coating machine, which is mainly used for the surface coating process production of insulation sheets, films, paper, etc. It is to coat the substrate with a layer of glue, coating or ink with specific functions, and then dry it. It uses a special multi-functional coating head, which can achieve various forms of surface coating.

[0003] A Chinese patent application with publication number CN218360372U discloses an automatic coating machine for thermal insulation sheets, comprising a workbench, a coating table and two vertical plates are fixedly arranged on the top of the workbench, the coating table is located between the two vertical plates, support rods are passed through the two vertical plates, a slider is slidably arranged on the support rods, an electric push rod is fixedly arranged on the side of one of the vertical plates facing the slider, the output shaft of the electric push rod is fixedly connected to the slider, a coating head is fixedly arranged on the bottom end of the slider, nuts are threadedly connected on both sides of the support rod, the coating head can be supported under the action of the support rod and the slider, when the position of the coating head needs to be adjusted, the slider only needs to be pushed by the output shaft of the electric push rod, which can effectively reduce the load on the output shaft of the electric push rod and avoid bending and deformation of the output shaft of the electric push rod, which is convenient and practical.

[0004] Although this patent can support the coating head through the support rod and the slider to prevent the piston rod of the electric push rod from bending and deformation, this patent does not have a thermal insulation sheet locking function. The thermal insulation sheet is placed directly on the coating table, which may easily cause the thermal insulation sheet to shift during the coating operation, and may easily cause some parts of the thermal insulation sheet to be unable to be evenly coated with glue, paint or ink with specific functions, affecting the coating effect. For this reason, we provide a thermal insulation sheet automatic coating device to solve the above problems. Utility Model Content
