Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0025] In this embodiment, the term "and / or" is merely a term used to describe the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone.

[0026] The terms "first" and "second" in the description and claims of this embodiment are used to distinguish different objects rather than to describe a specific order of objects. For example, a first target object and a second target object are used to distinguish different target objects rather than to describe a specific order of target objects.

[0027] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0028] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more than two. For example, multiple processing units refer to two or more processing units; multiple systems refer to two or more systems.

[0029] like Figures 1 to 6 As shown, this embodiment provides a coating machine, which coats the papers 9 one by one. When in use, the papers are loaded one by one, and the side to be coated faces upward.

[0030] Specifically, the coating machine includes a lower mounting frame 1, an upper mounting cover 2 arranged on the lower mounting frame 1, a paper conveying mechanism 4 and a coating actuator 5 arranged on the lower mounting frame 1 and placed in the upper mounting cover 2, an ink barrel 6, an ink oil pump 7 and an electromagnetic valve 8 arranged in the lower mounting frame 1, and a flip cabinet door 3 arranged on the upper mounting cover 2. The ink barrel 6, the ink oil pump 7, the electromagnetic valve 8 and the coating actuator 5 are connected in sequence by pipelines. Among them, the paper conveying mechanism 4 is placed at the lower part of the coating actuator 5.

[0031] In this embodiment, the paper transport mechanism 4 includes a left transport frame 401 and a right transport frame 402 fixed on the lower mounting frame 1, a rear shaft rod 403 and a front shaft rod 404 arranged between the left transport frame 401 and the right transport frame 402, a servo motor assembly 405 connected to the rear shaft rod 403 or the front shaft rod 404, a first pulley 406 respectively sleeved on one end of the rear shaft rod 403 and the front shaft rod 404, a second pulley 407 respectively sleeved on the other end of the rear shaft rod 403 and the front shaft rod 404, and a servo motor assembly 405 connected to the rear shaft rod 403 or the front shaft rod 404. The belt 408 between the upper and lower mounting frames 1 and the lower mounting frame 1 is provided with a paper support plate 409 disposed on the belt 408 and supporting the paper to be coated, a lifting cylinder mounting frame 410 disposed on the lower mounting frame 1, a plurality of guide slide bars 412 slidably mounted on the lifting cylinder mounting frame 410, a lifting cylinder 413 disposed at the bottom of the lifting cylinder mounting frame 410, a lifting bottom plate 411 disposed at the top of the lifting cylinder 413 and connected to the guide slide bar 412 and driven to rise and fall by the lifting cylinder 413, and a lifting support plate 414 disposed at the top of the lifting bottom plate 411 and matched with the lifting of the paper support plate 409. The belt transmission mechanism is provided with a photoelectric sensor mounting box 415, and a photoelectric sensor is disposed in the photoelectric sensor mounting box 415, and the photoelectric sensor collects the position signal of the paper support plate 409. When the paper support plate 409 carrying the paper to be coated moves to the coating station, the photoelectric sensor obtains a signal of being in place, the servo motor assembly 405 stops running, and the lifting cylinder 413 lifts the paper support plate 409, and the ink coating head 59 is used for coating. It should be noted that, since the belt 408 is elastic, when lifting, it is only necessary to lift and support the paper support plate 409 to ensure that the ink coating head 59 is reliably supported downward for coating. After coating, the lifting cylinder 413 falls downward, and the servo motor assembly 405 drives the paper support plate 409 to continue to move forward and unload the paper. After the paper is unloaded, the servo motor assembly 405 rotates in the opposite direction to drive the paper support plate 409 to move to the paper feeding position.

[0032] In addition, the coating actuator 5 of the present embodiment includes a rear rail mounting frame 51 and a front linear sliding module mounting frame 52 fixed on the lower mounting frame 1, a rail slider assembly 54 arranged on the rear rail mounting frame 51, a linear sliding module 53 arranged on the front linear sliding module mounting frame 52, a transverse moving linear sliding module 55 straddling the rail slider assembly 54 and the linear sliding module 53, a transverse sliding seat 56 slidingly arranged on the transverse moving linear sliding module 55, a longitudinal moving module 57 fixed on the transverse sliding seat 56 along the longitudinal direction, an ink coating head mounting seat 58 arranged on the longitudinal moving module 57, and an ink coating head 59 arranged on the ink coating head mounting seat 58 and facing the paper to be coated; the ink coating head 59 is connected to the solenoid valve 8 by a pipeline. Under the joint driving action of the linear sliding module 53, the transverse moving linear sliding module 55 and the longitudinal moving module 57, the three-axis coating movement of the ink coating head 59 is realized.

[0033] The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Any changes that adopt the design principles of the present utility model and are made through non-creative labor on this basis should fall within the protection scope of the present utility model.
