DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 3A coating machine for easy replacement of a coating roller comprises a machine body 1, a coating tank 2 and a coating roller 3 installed on the upper end of the coating tank 2. The upper surface of the coating tank 2 is symmetrically provided with disassembly grooves 21, and a hinge plate 211 is welded in the disassembly groove 21. The coating roller 3 is detachably installed on the hinge plate 211 through an installation component 23.

[0022] The roller body of the coating roller 3 is movably connected to the fixed shafts at both ends thereof, and its bottom end extends into the coating tank 2 and contacts with the coating, so that the coating roller 3 can rotate under force during coating, be evenly stained with the coating and coat the surface of the material.

[0023] See also Figure 2 A snap-fit ​​groove 22 is provided at the side end of the paint tank 2, and the snap-fit ​​groove 22 and the center points of the left hoop plate 231 and the right hoop plate 232 are located on a horizontal line.

[0024] Among them, the arrangement of the engaging groove 22 is to improve the installation stability of the coating roller 3 and to support the coating roller 3. When the coating roller 3 is engaged with the left hoop plate 231 and the right hoop plate 232, its two ends just engage with the engaging groove 22, further improving the stability, while avoiding the coating roller 3 from directly acting on the two hoop plates, reducing the pressure loss on the hoop plates.

[0025] To solve the technical problem of how to replace the coating roller of the coating machine, please refer to Figure 3-Figure 4 , this embodiment provides the following technical solutions:

[0026] The mounting assembly 23 includes a left hoop plate 231 and a right hoop plate 232 which are hinged to each other. The bottom of the left hoop plate 231 and the right hoop plate 232 are hinged to the hinge plate 211. The upper ends of the left hoop plate 231 and the right hoop plate 232 are fixedly connected by stud bolts 233. The side ends of the left hoop plate 231 and the right hoop plate 232 are connected to a spring 235 via a connecting plate 234. One end of the spring 235 is fixedly connected to the inner wall of the disassembly groove 21, and the other end thereof is fixedly connected to the lower surface of the connecting plate 234.

[0027] Specifically, when the coating roller 3 needs to be replaced, the two stud bolts 233 are removed, and then the coating roller 3 is lifted upward. At this time, the left hoop plate 231 and the right hoop plate 232 are forced to rotate outward, driving the connecting plate 234 to rotate outward and squeeze the spring 235 until the coating roller 3 is taken out from the hoop plate, and then the two ends of the new coating roller 3 are pressed toward the middle of the left hoop plate 231 and the right hoop plate 232 until they are engaged, and then the pressure on the coating roller 3 is released. The spring 235 is stretched by the elastic force, driving the left hoop plate 231 and the right hoop plate 232 to fit tightly with the surface of the coating roller 3, and finally the upper ends of the left hoop plate 231 and the right hoop plate 232 are fixedly connected with the stud bolts 233 to complete the replacement of the coating roller 3.

[0028] To solve the technical problem of how the coating machine performs coating, please refer to Figure 1 , this embodiment provides the following technical solutions:

[0029] A cylinder 11 is installed on the upper surface of the body 1, and the cylinder 11 is connected to a lifting platform 12 through a piston rod. A pressure roller 13 is installed in the lifting platform 12. A slide groove 14 is opened on the inner wall of the body 1, and the left and right ends of the lifting platform 12 form a sliding connection with the slide groove 14.

[0030] Specifically, after the coating roller 3 is replaced, sufficient coating is added to the coating tank 2, and the coating roller 3 is rotated until the surface of the coating roller 3 is stained with the coating, and then the film material is passed around the surface of the coating roller 3, and then the cylinder 11 is started, and the cylinder 11 drives the lifting platform 12 to move downward until the pressure roller 13 presses the film material against the surface of the coating roller 3, and the film material is moved by using an external traction mechanism. At this time, the coating roller 3 is rotated under force to coat the surface of the film.

[0031] Working principle: This coating machine is convenient for replacing the coating roller. When the coating roller 3 needs to be replaced, the cylinder 11 is started first. The cylinder 11 drives the pressure roller 13 to rise to the top through the lifting platform 12, and then the left and right stud bolts 233 are removed, and the coating roller 3 is lifted upward. At this time, the left hoop plate 231 and the right hoop plate 232 are forced to rotate outward, driving the connecting plate 234 to rotate outward and squeeze the spring 235 until the coating roller 3 is taken out from the hoop plate, and then the two ends of the new coating roller 3 are aligned with the middle of the left hoop plate 231 and the right hoop plate 232 and pressed until they are engaged, and then the pressure on the coating roller 3 is released. The spring 235 is driven by the elastic force to rotate the left hoop plate 231 and the right hoop plate 232 inward and close to the surface of the coating roller 3, and finally the stud bolt 233 is reinstalled on the upper ends of the left hoop plate 231 and the right hoop plate 232 to achieve replacement.
