Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Figures 1-3 The present invention relates to a spraying reciprocating mechanism for a printer developing roller, comprising a housing 10, a drive assembly 20, a spraying reciprocating assembly 40, and a control system.

[0020] In this embodiment:

[0021] The guide rail 30 is installed inside the housing 10.

[0022] The drive assembly 20 includes a motor 21, a first gear 22, a second gear 23, and a chain 24.

[0023] The first gear 22, the second gear 23, and the chain 24 are all located inside the housing 10, and the chain 24 is wound around the first gear 22 and the second gear 23. The motor 21 is located outside the housing 10 and is connected to the first gear 22 for transmission. The motor 21 drives the first gear 22 to rotate and drives the second gear 23 to rotate through the chain 24.

[0024] The control system is electrically connected to the motor 21 and is used to control the speed and direction of the motor 21. By controlling the speed and direction of the motor 21 through the control system, the movement speed and position of the spray gun 45 can be precisely controlled, improving the accuracy and efficiency of spraying.

[0025] The spraying reciprocating assembly 40 includes a connecting block 41, a power plate 42, a slider 43, a reciprocating tube 44, a spray gun 45, and a connecting component 46.

[0026] The connecting block 41 is located at the bottom of the chain 24 and connected to the power plate 42. The motor 21 drives the first gear 22 to rotate, and drives the connecting block 41 and the power plate 42 to move in a straight line through the chain 24. Specifically, when the motor 21 rotates forward, the connecting block 41 and the power plate 42 move forward, and when the motor 21 rotates in reverse, the connecting block 41 and the power plate 42 move backward.

[0027] The slider 43 is slidably mounted on the guide rail 30 and fixedly connected to the power plate 42. In this embodiment, there are two sliders 43.

[0028] The reciprocating tube 44 is horizontally arranged inside the housing 10, with one end connected to the power plate 42 and the other end extending through the opening 11 to the outside of the housing 10. A paint channel is provided inside the reciprocating tube 44, with one end connected to the spray gun 45 and the other end connected to the paint supply device via a hose. The spray gun 45 is used to spray paint onto the developing roller. In this embodiment, the length direction of the guide rail 30 is parallel to the axial direction of the reciprocating tube 44, and two sliders 43 are located on opposite sides of the reciprocating tube 44 on the power plate 42, making the reciprocating tube 44 more stable during operation.

[0029] The connecting assembly 46 includes two pin plates 461 and multiple positioning pins 462. One pin plate 461 is located below the power plate 42, and the pin plate 461 passes through the reciprocating tube 44. The power plate 42 and the two pin plates 461 are fixedly connected by multiple positioning pins 462.

[0030] The guide assembly 50 includes two guide rods 51 and two guide wheels 52. The two guide wheels 52 are vertically installed inside the housing 10 and close to the opening 11. Each guide rod 51 is equipped with a guide wheel 52. A guide area is formed between the two guide wheels 52. The reciprocating tube 44 extends to the outside of the housing 10 through the guide area and the opening 11, which improves the stability of the reciprocating motion of the spray gun 45 and further ensures the spraying quality.

[0031] When in use, the motor 21 is started, which drives the first gear 22 to rotate. The first gear 22 drives the second gear 23 to rotate via the chain 24. During the rotation, the chain 24 drives the connecting block 41 to move. The connecting block 41 drives the power plate 42 and the reciprocating tube 44 to reciprocate, thereby causing the spray gun 45 to spray the developing roller. During the spraying process, the paint is delivered to the spray gun 45 through the hose and the paint channel in the reciprocating tube 44, and sprayed out from the nozzle of the spray gun 45 to be evenly coated on the surface of the developing roller.

[0032] This application controls the direction of the motor 21 through the control system, and realizes the reciprocating motion of the spray gun 45 through the cooperation of the drive component 20 and the spraying reciprocating component 40, which can uniformly spray the developing roller and improve the spraying quality of the developing roller. This application has a simple structure, is easy to maintain, reduces production costs, and is suitable for large-scale production.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
