[0002] A spraying equipment is a device that can cover a protective layer or a decorative layer on the surface of a workpiece to be sprayed through a nozzle.

[0003] Generally, the size of the spraying port of the spraying equipment is fixed, which is inconvenient to adjust the size of the spraying port according to the processing requirements.

[0004] The existing publicly disclosed technical solution, with the publication number of CN220678259U, discloses a spraying equipment with a variable spraying outlet size, including a main body mechanism and an auxiliary mechanism. The auxiliary mechanism is located at the lower end of the main body mechanism. The main body mechanism includes a device body, a feeding hopper and a spraying pump. The main body mechanism also includes a conveying pipe, a discharging port, a sealing ring and an adjusting component. The conveying pipe is fixedly installed at the right end of the spraying pump, and the lower end of the conveying pipe extends into the interior of the device body. By installing the main body mechanism, when the device body is performing spraying operations, it can be replaced with spraying ports of different sizes according to the usage requirements, so that the device body can be applicable to different spraying operations, improving the flexibility and applicability of the device body.

Specific embodiments

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0027] The present utility model provides a technical solution:

[0028] Please refer to Figures 1 to 4, a spraying device with adjustable spraying outlet size, comprising a device main body 1. Inside the device main body 1, there is a paint bin for containing paint and a device bin for containing a spraying pump. A heat dissipation net 3 is installed on one side of the device bin. The paint bin is located above the device bin. At the front end of the device main body 1, there is a spraying assembly 4 for adjusting the spraying direction, and on the spraying assembly 4, there is a nozzle adjusting assembly 5 for adjusting the position of the spraying assembly 4. At the bottom of the device main body 1, there is a moving base 2 equipped with universal wheels;

[0029] The nozzle adjusting assembly 5 includes a guiding chute 501 opened at the front end of the device main body 1. Inside the guiding chute 501, a lifting screw rod 503 is installed. On the surface of the lifting screw rod 503, a lifting slider 504 is installed through a screw sleeve. At the front end of the lifting slider 504, there is an installation groove 505. Inside the installation groove 505, there is a rotating block 507. At the top of the rotating block 507, there is a power output end of an adjusting motor 506. At the front end of the rotating block 507, there is a connecting rod 508, and the end of the connecting rod 508 is fixed on the spraying assembly 4;

[0030] The spraying assembly 4 includes a connection head 401. At the front end of the connection head 401, there is a nozzle 403 connected. At the front end of the nozzle 403, a first-level outer interface 404 is threadedly connected. At the front end of the first-level outer interface 404, a second-level outer interface 405 is threadedly connected. At the front end of the second-level outer interface 405, a third-level outer interface 406 is threadedly connected. The lifting slider 504 and the rotating block 507 form a semi-surrounding structure through the installation groove 505, and the rotating block 507 can rotate in the installation groove 505 through the adjusting motor 506.

[0031] By adopting the above technical solution, the adjusting motor 506 can drive the rotating block 507 to rotate in the installation groove 505, thereby driving the connection head 401 to swing left and right on the lifting slider 504 through the connecting rod 508 to adjust the spraying direction of the nozzle 403. At the same time, the lifting slider 504 can slide up and down on the lifting screw rod 503 under the action of the screw sleeve to adjust the height of the nozzle 403, which is convenient for use. And because the front end of the nozzle 403 can be threadedly connected with the first-level outer interface 404, the second-level outer interface 405, and the third-level outer interface 406 in sequence. When it is necessary to change the size of the spraying outlet, directly select to disassemble and assemble the first-level outer interface 404, the second-level outer interface 405, and the third-level outer interface 406.

[0032] Specifically, as Figure 4 shown, at the top of the lifting screw rod 503, there is a power output end of a screw rod motor 502, and the screw rod motor 502 is fixedly installed on the top of the device main body 1 through bolts. One end of the lifting screw rod 503 is connected to the screw rod motor 502, and the other end of the lifting screw rod 503 is installed on the device main body 1 through a bearing;

[0033] The spraying assembly 4 further includes a connecting pipe 402 installed at the bottom of the connector 401, and the end of the connecting pipe 402 is fixed to a spraying pump installed in the equipment bin. The connector 401 is interconnected with the spraying pump through the connecting pipe 402. The primary external interface 404, the secondary external interface 405, and the tertiary external interface 406 are all conical structures, and the diameters of the primary external interface 404, the secondary external interface 405, and the tertiary external interface 406 decrease sequentially from the back to the front.

[0034] By adopting the above technical solution, the spraying pump sprays the paint through the connecting pipe 402 and the nozzle 403 on the connector 401. When the primary external interface 404, the secondary external interface 405, and the tertiary external interface 406 are fully installed, the size of the spray outlet is the smallest. On the contrary, when the primary external interface 404, the secondary external interface 405, and the tertiary external interface 406 are fully disassembled, the size of the spray outlet is the largest. Thus, the size of the spray outlet can be changed, and the change in the size of the spray outlet will not affect the nozzle 403. The connector 401 and the connecting rod 508 can be set to be detachably connected. Even if the connector 401 is disassembled, it will not affect the normal use of the nozzle 403.

[0035] Working principle: The adjusting motor 506 can drive the rotating block 507 to rotate in the installation groove 505, thereby driving the connector 401 to swing left and right on the lifting slider 504 through the connecting rod 508 to adjust the spraying direction of the nozzle 403. Start the lead screw motor 502, and the lead screw motor 502 can drive the lifting lead screw 503 to rotate. At this time, the lifting slider 504 can slide up and down on the lifting lead screw 503 under the action of the lead screw sleeve to adjust the height of the nozzle 403 for convenient use. The spraying pump sprays the paint through the connecting pipe 402 and the nozzle 403 on the connector 401. When the primary external interface 404, the secondary external interface 405, and the tertiary external interface 406 are fully installed, the size of the spray outlet is the smallest. On the contrary, when the primary external interface 404, the secondary external interface 405, and the tertiary external interface 406 are fully disassembled, the size of the spray outlet is the largest. The heat dissipation net 3 can allow external air to enter the equipment bin to dissipate heat from the spraying pump in the equipment bin.

[0036] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
