Description

Technical Field

[0001] The utility model relates to the technical field of self-adhesive coating machines, in particular to a self-adhesive coating machine with adjustable coating thickness. Background Art

[0002] A self-adhesive coating machine is a device used to apply glue or adhesive on materials, and is commonly used to manufacture products such as labels, stickers, and tapes. It can accurately control the coating thickness and uniformity of the glue, improve production efficiency and product quality, and the application number is: CN202120913984.8. A self-adhesive coating machine with adjustable coating thickness is disclosed, including a bottom plate, and a first vertical plate and a second vertical plate are fixedly arranged on both sides of one end of the top of the bottom plate, and a motor is fixedly installed at the bottom end of one side of the second vertical plate. The output end of the motor is fixedly connected to a coating roller through the second vertical plate. The patent adjusts the extrusion roller by setting two threaded columns, but the adjustment requires the two threaded columns to rotate at the same time, which is difficult to operate and difficult to achieve synchronous rotation, which easily leads to the tilt of the extrusion roller and affects the use. Therefore, we introduce a self-adhesive coating machine with adjustable coating thickness. Utility Model Content

[0003] The main purpose of the utility model is to provide a self-adhesive coating machine with adjustable coating thickness, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A self-adhesive coating machine with adjustable coating thickness comprises a connecting seat, a drying box is fixedly connected to the front of the upper end of the connecting seat, a lifting device is fixedly connected to the middle of the upper end of the connecting seat, a bracket is fixedly connected to the rear of the upper end of the connecting seat, the bracket is a "U"-shaped structure, and slide grooves are provided at the left and right ends of the bracket. A motor is fixedly connected to the lower right end of the bracket, a No. 1 connecting roller is fixedly connected to the output end of the motor, a coating roller is installed on the outer surface of the No. 1 connecting roller, and an adjustment mechanism is fixedly connected to the upper end of the bracket.

[0006] Preferably, the lifting device includes a base, the upper end of the base is a curved surface structure, and the upper end of the base is movably connected with a No. 4 lifting roller, a No. 3 lifting roller, a No. 2 lifting roller and a No. 1 lifting roller in sequence from front to back, the height of the No. 1 lifting roller is higher than the height of the No. 2 lifting roller, the height of the No. 2 lifting roller is higher than the height of the No. 3 lifting roller, and the height of the No. 3 lifting roller is higher than the height of the No. 4 lifting roller.

[0007] Preferably, the base is fixedly connected to the connecting seat.

[0008] Preferably, a No. 2 through hole is formed at the left portion and the right portion of the upper end of the bracket, and a No. 1 through hole is formed at the middle portion of the upper end of the bracket.

[0009] Preferably, the adjustment mechanism includes an electric push rod, the telescopic end of the electric push rod is fixedly connected to a sliding frame, the upper left and upper right parts of the sliding frame are fixedly connected to a limiting rod, the inner wall of the sliding frame is fixedly connected to a No. 2 connecting roller, and the outer surface of the No. 2 connecting roller is installed with an extrusion roller.

[0010] Preferably, the electric push rod is fixedly connected to the upper end of the bracket, the telescopic end of the electric push rod passes through the No. 1 through hole, the two limit rods are movably connected with the two No. 2 through holes respectively, and the sliding frame is slidably connected with the two sliding grooves.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. By setting a lifting device, the lifting device is set between the bracket and the drying box. Since the heights of the No. 1 lifting roller, the No. 2 lifting roller, the No. 3 lifting roller and the No. 4 lifting roller are arranged from high to low, the material can be lifted when it enters the drying box from the bracket, thereby preventing the material from contacting with the connecting seat and being contaminated with dust;

[0013] 2. By setting up the adjustment mechanism and starting the electric push rod, the electric push rod pushes the sliding frame to move up and down, so that the height of the extrusion roller in the sliding frame can be adjusted. Since the sliding frame slides in the two slide grooves and the two limit rods are interlaced with the bracket, under the limiting action of the two limit rods and the sliding frame, the stability of the extrusion roller during adjustment can be improved to avoid tilting.
