The nozzle 10 is an ink jet mechanism, and is mounted on a guide rail and slide block mechanism for horizontal movement.

The base 1 is arranged at one end of the spray head 10 in the horizontal moving direction, and the base 1 is a main body of the maintenance device and mainly comprises a bottom plate and two side plates; a scraper is further arranged on one side of the base 1, which is close to the spray head 10, and the spray head 10 can be scraped by the scraper when passing through the scraper. The two side plates of the base 1 are symmetrically provided with the sliding grooves 100, the two ends of the sliding grooves 100 extend along the preset moving direction of the movable part 2, and each side plate is provided with at least two sliding grooves 100, so that the movable part 2 is prevented from rotating in the base 1.

The movable part 2 is arranged on the base 1 and is provided with a groove, and the spray head 10 can be inserted into the groove so as to cover the spray head 10 to realize the moisture preservation of the spray head 10. Since the movable portion 2 can move up and down during the process of closing the cap or separating from the spray head 10, and if the movable portion 2 and the spray head 10 are required to be driven, the movable portion 2 and the spray head 10 can be preset to move synchronously and simultaneously along the plumb line direction, and the moving track of the movable portion 2 is a diagonal line.

The abutting portion 3 is provided on one end of the movable portion 2 away from the head 10 and moves in synchronization with the movable portion 2. The abutting part 3 is used for driving the movable part 2 to synchronously move along with the spray head 10 when the spray head 10 abuts against and pushes the abutting part 3. In order to buffer the impact force of the head 10 on the abutting portion 3, an elastic pad 31 is provided on the end surface of the abutting portion 3 facing the head 10.

The slide pin 4 is provided on the movable portion 2 and moves synchronously with the movable portion 2.

The reset component 5 is arranged on the base 1; the slide pin 4 is inserted into the slide groove 100 and moves along the slide groove 100; the reset component 5 is used for enabling the movable part 2 to move and reset when the spray head 10 is separated from the abutting part 3.

Specifically, the reset assembly 5 includes a slider 51 and a first elastic member 52.

The first elastic member 52 may be a spring.

With the technical scheme, the spray head 10 moves towards the maintenance device and contacts the abutting part 3, and as the spray head 10 continues to move, the abutting part 3 is pushed to drive the movable part 2 to move, and as the sliding pin 4 moves along the sliding groove 100, the movable part 2 moves up while translating, and finally the movable part 2 abuts against and covers the spray head 10, at this time, the abutting part 3 pushes the sliding block 51 and compresses the first elastic piece 52; when the spray head 10 moves away from the maintenance device and is separated from the abutting part 3, the first elastic piece 52 rebounds and pushes the sliding block 51 and the abutting part 3 to move reversely, and the movable part 2 also moves reversely in a translational manner and descends until reset.

The position of the movable part 2 is the initial position when the preset supporting part 3 is separated from the spray head 10, and the position of the preset movable part 2 for covering the spray head 10 is the final position; the distance between the initial position and the final position in the horizontal direction is the same as the length of the chute 100 in the direction of movement of the head 10. The initial position and the final position are the same distance along the plumb line as the two ends of the chute 100.

Example two

In addition to the first embodiment, in order to limit the horizontal movement of the slider 51 without moving up and down, as shown in fig. 1, in conjunction with fig. 6, the reset assembly 5 further includes a shaft 53 and a sleeve 54.

Wherein one end of the shaft 53 is fixedly connected to the slider 51 and the other end of the shaft extends outwards through the base 1 along the moving direction of the spray head 10; the shaft 53 moves synchronously with the slider 51 with respect to the base 1. The shaft 53 restricts the moving direction of the slider 51.

The sleeve 54 is fixedly arranged on the base 1 and two ends of the sleeve extend along the head moving direction; a shaft 53 is inserted into the sleeve 54. The sleeve 54 serves to guide the movement of the shaft 53.

Example III

With the above technical solution, when the movable portion 2 is driven to rise, the second elastic member 55 is elastically stretched; when the nozzle 10 is separated from the supporting portion 3, the second elastic member 55 rebounds and pulls the movable portion 2 to descend.

Example IV

In addition to the first embodiment, a roller 6 is further included to enable smooth movement of the slide pin 4 in the slide groove 100.

Wherein, the idler wheel 6 is sleeved on the sliding pin 4 and rotates relative to the sliding pin 4; the roller 6 is disposed in the chute 100 and rolls along the chute 100. The roller 6 may be a sheave that is clamped to the edge of the chute 100.
