Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic powder spraying, in particular to a spraying device which is convenient for adding electrostatic powder. Background Art

[0002] The working principle of electrostatic powder spraying is almost the same as that of general liquid paint electrostatic spraying. The difference is that powder spraying is dispersed rather than atomized. It is the paint sprayed out by an electrostatic powder spray gun. The powder particles are negatively charged while being dispersed. The charged powder particles are affected by airflow and electrostatic attraction and are coated on the grounded object to be coated. They are then heated, melted and solidified into a film. Electrostatic powder spraying is the dominant powder coating method in the field of industrial coating. In order to ensure that the spraying equipment can carry out spraying operations continuously and evenly, some patents have begun to improve the feeding mechanism of the spraying equipment.

[0003] For example, in the patent with authorization announcement number CN215878416U, by putting excess material into the feed box to fill the lifting box, the lifting box descends and the reset spring is compressed, the downward movement of the vertical rack drives the first gear to rotate, the first gear drives the second bevel gear to rotate through the first rotating shaft and the first bevel gear, the second bevel gear drives the gear ring to rotate through the second rotating shaft and the second gear, so that the semicircular closing plate rotates, and when the material in the lifting box is reduced due to use, the weight of the lifting box is reduced, the reset spring is gradually reset, and the closing plate rotates and gradually opens, and the above process is repeated, so that the material in the lifting box is generally in a sufficient state, and the concentration of the material powder sprayed by the spray gun is sufficient and uniform. However, there are still certain shortcomings.

[0004] The common shortcoming of the above patent and the prior art is that when adding powder material, the above patent needs to open the feed box and put excessive material into the feed box. In this process, due to the light weight of the powder material, when adding material, the air inside the feed box is squeezed and gushed upward, which will drive the powder to fly outward, causing waste of material and polluting the surrounding environment. It may be inhaled into the body of the staff and cause harm to the staff. Utility Model Content

[0005] In response to the above problems, the present application provides a spraying equipment that is convenient for adding electrostatic powder, so as to solve the problem that when adding powder material, due to the light weight of the powder material, when adding the material, the air inside the feed box is squeezed and sprayed upward, which will drive the powder to fly outward, causing waste of material and polluting the surrounding environment. It may be inhaled into the body of the staff and cause harm to the staff.

[0006] The technical solution of the utility model is: a spraying equipment which is convenient for adding electrostatic powder, comprising a material storage box, a cover plate is installed in contact with the top of the material storage box, a feeding box is installed in contact with the bottom of the cover plate, a conical plate is installed in contact with the bottom of the feeding box, a spring is fixedly installed between the top of the conical plate and the bottom of the cover plate, a matching groove is opened at the bottom of the conical plate, a stopper is symmetrically fixedly installed at the bottom of the matching groove, an electric telescopic rod is fixedly installed at the bottom inside the material storage box, and a linkage block is fixedly installed at the telescopic end of the electric telescopic rod.

[0007] Furthermore, the gap between the two stoppers is larger than the width of the linkage block, and the gap between the two stoppers is smaller than the length of the linkage block.

[0008] Furthermore, a sealing groove is provided on the top of the material storage box, a sealing strip is slidably installed inside the sealing groove, and the sealing strip is fixedly installed on the bottom of the cover plate.

[0009] Furthermore, two handles are symmetrically fixedly mounted on the top of the cover plate.

[0010] Furthermore, a movable base is fixedly installed on the bottom of the storage box, and a nozzle box is fixedly installed on the top of the movable base.

[0011] Furthermore, a through hole is formed through the outer side of the material storage box near the bottom, and a connecting pipe is fixedly installed between the through hole and the feeding end of the nozzle box.

[0012] The beneficial effects of the utility model are as follows:

[0013] The utility model discloses a spraying device which is convenient for adding electrostatic powder. When adding powder to a material storage box, a staff member uses a handle to put the feeding box into the material storage box, a linkage block enters a matching groove, a sealing strip enters a sealing groove, and a cover plate seals the material storage box to prevent powder from floating out from the top of the material storage box. The staff member rotates the feeding box 90 degrees, and the telescopic end of the electric telescopic rod shortens, thereby squeezing and driving the stopper and the conical plate downward, and the powder inside the feeding box is replenished from the bottom of the feeding box to the material storage box.

It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0023] like Figure 1-Figure 6 As shown, the embodiment of the utility model provides a spraying equipment which is convenient for adding electrostatic powder, including a storage box 3, a cover plate 4 is installed in contact with the top of the storage box 3, a feeding box 8 is installed in contact with the bottom of the cover plate 4, and powder is filled inside, and a conical plate 10 is installed in contact with the bottom of the feeding box 8. The conical design of the top of the conical plate 10 is conducive to the complete discharge of the powder inside the feeding box 8, and a spring 9 is fixedly installed between the top of the conical plate 10 and the bottom of the cover plate 4, which is used to drive the conical plate 10 to move up and reset. In the absence of external force, the tension of the spring 9 can drive the conical plate 10 to seal the bottom of the feeding box 8 to ensure that the powder inside the feeding box 8 will not leak out during the transportation of the feeding box 8, a matching groove 13 is opened at the bottom of the conical plate 10, and a stopper 14 is symmetrically fixedly installed at the bottom of the matching groove 13, an electric telescopic rod 11 is fixedly installed at the bottom of the inner side of the storage box 3, and a linkage block 12 is fixedly installed at the telescopic end of the electric telescopic rod 11.

[0024] In this embodiment, when adding powder for the first time, when adding powder to the storage box 3, the staff holds the handle 5 and places the feeding box 8 into the storage box 3, and the linkage block 12 enters the matching groove 13. The staff rotates the feeding box 8 90 degrees and starts the electric telescopic rod 11. The telescopic end of the electric telescopic rod 11 shortens, thereby squeezing and driving the block 14 and the conical plate 10 to move downward, and the spring 9 is stretched. The powder inside the feeding box 8 is replenished from the bottom of the feeding box 8 to the storage box 3, and the conical design at the top of the conical plate 10 is conducive to the complete discharge of the powder inside the feeding box 8.

[0025] When adding powder subsequently, the staff starts the electric telescopic rod 11, the telescopic end of the electric telescopic rod 11 extends, and the conical plate 10 moves up and resets under the elastic force of the spring 9. The staff rotates the feeding box 8 in the opposite direction by 90 degrees, and then moves the storage box 3 and the cover plate 4 up and takes them out, and then replenishes the powder according to the steps of adding powder for the first time.

[0026] Specifically, the gap between the two stoppers 14 is larger than the width of the linkage block 12 and smaller than the length of the linkage block 12 .

[0027] Specifically, a sealing groove 6 is opened on the top of the material storage box 3 , a sealing strip 7 is slidably installed inside the sealing groove 6 , and the sealing strip 7 is fixedly installed on the bottom of the cover plate 4 .

[0028] In this embodiment, the sealing strip 7 cooperates with the sealing groove 6 to seal the top of the storage box 3. When replenishing materials, powder will not float out from the top of the storage box 3, which will not cause material waste and can also ensure a safer working environment for the staff.

[0029] Specifically, two handles 5 are symmetrically fixedly mounted on the top of the cover plate 4 .

[0030] In this embodiment, the handle 5 makes it convenient for the staff to move the cover plate 4.

[0031] Specifically, a movable base 1 is fixedly installed on the bottom of the material storage box 3, and a nozzle box 2 is fixedly installed on the top of the movable base 1.

[0032] In this embodiment, universal wheels are installed at the bottom of the mobile base 1 to facilitate the staff to move the device to the actual work location.

[0033] Specifically, a through hole is formed through the outer side of the storage box 3 near the bottom, and a connecting pipe 15 is fixedly installed between the through hole and the feeding end of the nozzle box 2 .

[0034] In this embodiment, the worker starts the nozzle box 2 to spray the powder inside the storage box 3 from the connecting pipe 15 and the spray gun of the nozzle box 2.

[0035] How it works:

[0036] When adding powder for the first time, when adding powder to the storage box 3, the staff carries the handle 5 and puts the feeding box 8 into the storage box 3, the linkage block 12 enters the matching groove 13, and the sealing strip 7 enters the sealing groove 6, so that the cover plate 4 seals the storage box 3 to prevent the powder from floating out from the top of the storage box 3. The staff rotates the feeding box 8 90 degrees and starts the electric telescopic rod 11. The telescopic end of the electric telescopic rod 11 shortens, thereby squeezing and driving the block 14 and the conical plate 10 to move downward, and the spring 9 is stretched. The powder inside the feeding box 8 is replenished from the bottom of the feeding box 8 to the storage box 3, and the conical design at the top of the conical plate 10 is conducive to the complete removal of the powder inside the feeding box 8.

[0037] The staff starts the nozzle box 2 to spray the powder inside the storage box 3 from the connecting pipe 15 and the spray gun of the nozzle box 2.

[0038] When adding powder subsequently, the staff starts the electric telescopic rod 11, the telescopic end of the electric telescopic rod 11 extends, and the conical plate 10 moves up and resets under the elastic force of the spring 9. The staff rotates the feeding box 8 in the opposite direction by 90 degrees, and then moves the storage box 3 and the cover plate 4 up and takes them out, and then replenishes the powder according to the steps of adding powder for the first time.

[0039] The powder inside the feeding box 8 is filled automatically by the manufacturer with the help of machinery. The existing technology can be realized by various technical means, which will not be described in detail in this article.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
