Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to a paint spraying device for plate production. Background Art

[0002] Furniture panels need to be painted during processing and production. On the one hand, it can prevent moisture and insects, and on the other hand, it can also enhance the aesthetics of the furniture.

[0003] In the process of making furniture, it is necessary to spray paint on the panels of the furniture. The existing painting equipment uses multiple nozzles to spray paint continuously during painting. However, the widths of the panels are different, and the paint sprayed by some nozzles cannot reach the panels but instead sprays outside the panels. Although a device is provided to redirect the excess paint into a paint storage bucket for easy recycling, the sprayed paint will be contaminated with dust in the external environment to a certain extent, and repeated circulation will accumulate in the paint storage bucket, affecting the quality of subsequent panel painting. Summary of the invention

[0006] The beneficial effects of the utility model are: adding a limit plate and an opening and closing piece to ensure that the spraying range of the spray head in the working state is consistent with the width of the wooden board, closing the ineffective spray head, reducing the phenomenon of ineffective spraying of a large amount of paint, and improving the effect of spraying the wooden board.

[0007] As a further improvement of the utility model, the technical problem to be solved is: how to use the opening and closing member to close the ineffective spraying spray head so that the working spray head maintains the same width as the plate to be painted.

[0008] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the opening and closing member includes two movable plates which are arranged under the installation box in a mirror-image manner, a plurality of adjusting gear blocks are arranged outside the installation sleeve of the spray head, and a plurality of power-assisting gear blocks which mesh with the adjusting gear blocks are arranged on the bottom surfaces of the two movable plates, and the power-assisting gear blocks and the plurality of spray heads on the two movable plates are symmetrically arranged with respect to the central axis of the conveying platform.

[0009] The beneficial effect of the above improvement is: the auxiliary tooth block on the bottom of the movable plate is engaged with the adjustment tooth block outside the sprinkler head to achieve the effect of rotating the sprinkler head, and realize the effect of the connection between the sprinkler head and the auxiliary pipe from connection to dislocation and closure.

[0010] The utility model further improves the technical solution adopted as follows: the transmission member includes mounting plates arranged on both sides of the conveying platform and electric push rods horizontally arranged on the mounting plates, whose telescopic ends are fixedly connected to the outer side surfaces of the corresponding limit plates; the outer side surfaces of the limit plates are also provided with connecting rods fixedly connected to the outer ends of the moving plates.

[0011] The beneficial effects of the above improvements are: the corresponding electric push rods are used to realize the synchronous movement of the two limit plates, and the connecting rod is used to realize the synchronous and equal-distance movement of the moving plate and the limit plate, so as to achieve the effect of closing the spray head at the corresponding position, wherein the stroke of the moving plate is not completely converted into the rotation arc length of the spray head, that is, the initial state of the power-assisting tooth block on the bottom surface of the moving plate may not be engaged with the adjusting tooth block on the spray head. In actual situations, the position of the power-assisting tooth block on the bottom surface of the moving plate can be adjusted to achieve the above effect, thereby avoiding the situation where paint cannot be sprayed on both sides of the wooden board.

[0012] The utility model further improves the technical solution adopted as follows: a plurality of power-assisting rollers for improving the moving ability of the wooden board on the conveying platform are rotatably arranged on the inner side surfaces of the two limit plates.

[0013] The beneficial effect of the above improvement is as follows: since the function of the limit plate is to keep the wooden board in a centered state on the conveyor platform, the assisting roller can reduce the rigid clamping friction force of the limit plate on the wooden board.

[0014] The utility model further improves the technical solution adopted as follows: the main pipe is mirror-symmetrically provided with a positioning block matched with the corresponding spray head, the positioning block is made of magnet material, and the spray head can be made of rubidium magnet material.

[0015] The beneficial effects of the above improvement are: the positioning block is used to achieve magnetic fixation of the sprinkler head, so that when multiple sprinkler heads are gradually closed from both sides to the middle, they remain in a closed state, and when the movable plate moves back, it can be broken off from the positioning block to cancel the positioning.
