Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spraying, in particular to a full-automatic powder electrostatic spraying device. Background Art

[0002] Fully automatic powder electrostatic spraying equipment is an automated equipment. With the development of powder coatings and spraying equipment, powder spraying equipment is one of the necessary tools for electrostatic powder spraying.

[0003] When performing powder spraying, the spraying environment is relatively closed, and the sprayed powder will fill the spray room. Some of the powder will fall on the accessories that need to be sprayed, some will fall on the ground, and some will fall on the nozzle, which will cause the nozzle to be blocked. The blocked nozzle will affect the normal spraying of the powder. After the blockage, the flow rate of the nozzle pipeline will be reduced. If the powder driving force remains unchanged, the pipeline may be broken by the accumulated powder, which will affect the normal use of the equipment. In addition, the blocked nozzle will also affect the spraying efficiency of the powder. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0024] A fully automatic powder electrostatic spraying device provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0025] Combination Figure 1-5 As shown, the utility model provides a fully automatic powder electrostatic spraying device, including a base 1, a connecting pipe 3 is fixedly connected to the side wall of the base 1, a bracket 4 is fixedly connected to both sides of the connecting pipe 3, a transport pipe 5 is fixedly connected to one side of the bracket 4, a transport pipe 7 is fixedly connected to one end of the transport pipe 5, and a connector 10 is fixedly connected to one end of the transport pipe 7;

[0026] One end of the connector 10 is fixedly connected to a nozzle 12, one end of the nozzle 12 is fixedly connected to a spring tube 14, the inner wall of the spring tube 14 is fixedly connected to a limit block 17, the top of the limit block 17 is fixedly connected to a threaded tube 18, the top of the threaded tube 18 is fixedly connected to a push plate 20, the side wall of the push plate 20 is slidably connected to a buffer tube 21, the top of the buffer tube 21 is fixedly connected to a booster sheet 15, the side wall of the booster sheet 15 is fixedly connected to a bellows 16, the inner wall of the bellows 16 is fixedly connected to an air bag 19, and the outer wall of the nozzle 12 is fixedly connected to a support ring 13;

[0027] One end of the transport pipe 5 is fixedly connected to a fixed block 6, one end of the transport pipe 7 is fixedly connected to one end of the fixed block 6, the side wall of the base 1 is fixedly connected to a baffle 8, the baffle 8 is provided with a through groove, the transport pipe 7 is fixedly connected to the inner wall of the through groove in a through shape, the top of the base 1 is fixedly connected to the power box 2, the side wall of the limit block 17 is annularly fixedly connected to a sliding rod 22, one end of the sliding rod 22 is slidably connected to the inner wall of the spring tube 14, the number of vertically arranged fixed blocks 6 is five, and one end of the fixed block 6 is fixedly connected to a fixed rod 23.

[0028] In the first embodiment, when the powder is transported through the transport tube 5, the thrust of the powder is used to squeeze the spring tube 14 at one end of the nozzle 12. The powder entering the spring tube 14 will drive the limit block 17 to slide. The spring tube 14 is used mainly because the pipeline may be broken when the impact force is too large. When the limit block 17 moves, it can drive the threaded tube 18 to move, and when it moves, it can drive the push plate 20 to move. The push plate 20 is separated from the airbag 19 to allow the powder to enter the buffer tube 21. Entering the buffer tube 21 will cause the buffer tube 21 to expand, and the expansion can provide protection. At the same time, when encountering a discharge port, the elastic force recovered by the expansion can be used to push the powder out. The powder before the buffer tube 21 will squeeze the booster sheet 15. When it is squeezed to a certain force, it can be ejected out. In this way, the powder blocked at the nozzle 12 port can be pushed out. On the one hand, it can ensure that the nozzle 12 will not be blocked. On the other hand, the powder dropped on the nozzle 12 can be ejected again for reuse.

[0029] The inner wall of the conveying tube 7 is rotatably connected with a conveying rod 9 , one end of the conveying rod 9 is rotatably connected to one side of a connector 10 , and a through hole 11 is opened on one side of the connector 10 .

[0030] In the second embodiment, the conveying rod 9 can drive the powder to move when rotating, and the powder can be stably conveyed when moving, thereby preventing the powder from accumulating in the pipeline and being unable to flow normally, thereby breaking the pipeline and affecting the service life of the equipment.

[0031] The working principle and use process of the utility model are as follows: when the powder enters the conveying tube 7 through the conveying tube 5, the blowing force that pushes the powder to move acts on the conveying rod 9 to allow the conveying rod 9 to rotate. When the conveying rod 9 rotates, it can drive the powder to move. When the powder moves to the connecting head 10, it will enter the spring tube 14 in the nozzle 12 through the through hole 11. Then, the powder accumulates and pushes the limit block 17 to move. The movement of the limit block 17 will drive the push plate 20 on the threaded tube 18 to move. When the push plate 20 moves, it can push the powder into the buffer tube 21, and then the powder is sprayed out through the pressure of the booster plate 15.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
