Description

Technical Field

[0001] The utility model relates to the technical field of spraying devices, and more specifically, to a high-viscosity paint spraying device. Background Art

[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid made of organic solvents or water, mainly based on resin, oil, or emulsion, with or without added pigments and fillers and corresponding additives.

[0003] When operators are performing paint construction, they often use a spray device. Although the existing spray device has basic spraying functions during use, some paint often remains inside the nozzle after spraying, and the paint will solidify. With long-term operation, the amount of solidified paint inside the nozzle will also increase, which will eventually affect the operation of the nozzle. The existing spray device is not convenient for disassembly and cleaning of the nozzle, so it needs to be improved. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a high-viscosity paint spraying device, which has the advantage that the spray head is easy to disassemble.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a high-viscosity paint spraying device, comprising:

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 5 As shown, the utility model provides a high-viscosity paint spraying device, comprising:

[0027] A bottom plate 1, a box body 2 is fixedly installed on the right side of the top of the bottom plate 1, a paint pump 3 is fixedly installed in the middle of the left bottom end of the box body 2, a material extraction port 18 is fixedly installed on the right side of the paint pump 3, and the right end of the material extraction port 18 penetrates the box body 2 and extends to the inner surface of the box body 2;

[0028] A discharge pipe 20, the bottom of which is fixedly connected to the upper end of the paint pump 3, the other end of which is fixedly connected to a hose 4, the lower surface of which is movably connected to a support plate 8, the bottom end of which is fixedly connected to the left side of the top of the box body 2, and the other end of which is movably connected to a nozzle 5;

[0029] A fixing mechanism, which is arranged at the top of both sides of the nozzle 5;

[0030] Among them, the fixing mechanism includes a cylindrical pin 6, the outer surface of the cylindrical pin 6 is movably connected to the inside of the nozzle 5, the left side of the cylindrical pin 6 passes through the nozzle 5 and the hose 4 in sequence and extends to the inside of the hose 4, the right end of the cylindrical pin 6 passes through the nozzle 5 and extends to the outside of the nozzle 5 and is fixedly connected with a pull block 19, the outer surface of the cylindrical pin 6 is movably connected with a spring 7, one end of the spring 7 is fixedly connected to the left side of the pull block 19, and the other end of the spring 7 is fixedly connected to the outer surface of the nozzle 5.

[0031] When the pull block 19 is pulled outward, the left end of the cylindrical pin 6 will be disengaged from the inside of the hose 4, and the spring 7 is in a stretched state at this time, thereby releasing the fixing effect between the hose 4 and the nozzle 5. Then the operator can remove the nozzle 5 from the outer surface of the hose 4 to clean the inside of the nozzle 5.

[0032] Among them, rollers 9 are movably installed at the four corners of the bottom of the bottom plate 1, and push rods 10 are fixedly installed at the front and rear sides of the right side of the top end of the bottom plate 1.

[0033] Due to the arrangement of the rollers 9 and the push rod 10, the operator can transport in different directions.

[0034] A feed pipe 11 is fixedly installed on the left side of the top of the box body 2, and a support column 12 is fixedly connected to the right side of the top of the box body 2.

[0035] The provision of the feed pipe 11 facilitates the operator to load the paint.

[0036] A motor 13 is fixedly mounted on the top of the support column 12 , and a rotating shaft 14 is fixedly sleeved on the other end of the output shaft of the motor 13 .

[0037] When the motor 13 is running, the rotating shaft 14 will rotate.

[0038] A gear 15 is fixedly sleeved on the outer surface of the rotating shaft 14 , and a toothed plate 16 is meshedly connected on the outer surface of the gear 15 .

[0039] When the rotating shaft 14 starts to rotate, it drives the gear 15 to rotate, and the toothed plate 16 meshing with the outer surface of the gear 15 moves downward.

[0040] The bottom end of the tooth plate 16 is fixedly connected with a scraper 17 , and the outer surface of the scraper 17 is movably connected to the inner surface of the box body 2 .

[0041] When the toothed plate 16 moves downward, it will also drive the scraper 17 to move downward. At this time, the bottom of the scraper 17 will scrape the inner surface of the box 2, so that the paint attached to the inner surface of the box 2 can fall off for subsequent use.

[0042] The inner surface of the box body 2 is smooth, and the bottom of the inner cavity of the box body 2 is inclined.

[0043] Since the bottom end of the inner cavity of the box body 2 has a certain inclination angle, it is more conducive to the extraction of paint.

[0044] The working principle and use process of this utility model:

[0045] First, the operator adds the paint into the interior of the box 2 through the feed pipe 11, then picks up the hose 4 and starts the paint pump 3. At this time, the suction port 18 will extract the paint inside the box 2, and then introduce it into the interior of the hose 4 through the discharge pipe 20, and finally it will be sprayed out by the nozzle 5 to carry out the spraying operation. When the paint liquid level inside the box 2 begins to drop, the operator starts the motor 13, driving the rotating shaft 14 and the gear 15 to rotate, and then driving the tooth plate 16 meshing with the outer surface of the gear 15 to move downward, so that the tooth plate 16 drives the scraper 17 to move downward on the inner cavity surface of the box 2, and the paint attached to the inner surface of the box 2 can be scraped off for use.

[0046] When the nozzle 5 is in long-term use, a large amount of solidified paint will accumulate inside the nozzle 5. At this time, the operator can pull the pull block 19 to make the left end of the cylindrical pin 6 detach from the inside of the hose 4, thereby releasing the fixing effect between the hose 4 and the nozzle 5. Then the operator can remove the nozzle 5 from the outer surface of the hose 4 to clean the inside of the nozzle 5.
