Description

Technical Field

[0001] The utility model discloses a graphene powder coating spraying device, belonging to the field of graphene spraying. Background Art

[0002] Graphene is a two-dimensional crystal with atomic thickness of carbon atoms peeled off from graphite material. Common methods for producing graphene powder are mechanical exfoliation, redox method, SiC epitaxial growth method, and thin film production method is chemical vapor deposition method. Due to its excellent strength, flexibility, electrical conductivity, thermal conductivity, and optical properties, it has made great progress in physics, materials science, electronic information, computers, aerospace and other fields. Graphene has very far-reaching application prospects in conductive coatings, anti-corrosion coatings, flame retardant coatings, thermal conductive coatings and high-strength coatings. In the prior art, because graphene coatings are in powder form, at the beginning of each use of the nozzle, the powder will accumulate for a long time, which will cause the discharge port to be blocked. Manual cleaning of the discharge port is troublesome and delays the spraying progress. Therefore, it is necessary to design a graphene powder coating spraying device that can clear the discharge port on the nozzle when the nozzle starts spraying. Utility Model Content

The utility model facilitates unblocking the discharge port before the nozzle is used to improve the spraying efficiency.

[0004] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a graphene powder coating spraying device, comprising a fixed base plate, a support plate is installed on one side of the fixed base plate, a top plate is installed on the upper part of the support plate on the same side as the fixed base plate, a hydraulic rod is installed on the top of the top plate, a nozzle is installed at the bottom of the hydraulic rod, a protective cover is installed directly below the nozzle, the protective cover is installed inside the fixed base, the bottom of the fixed base is connected and fixed to the fixed base plate, an anti-slip part is installed inside the fixed base, one side of the anti-slip part is connected to the protective cover, a dredging structure is installed on the top of the protective cover, and the dredging structure is connected to the bottom of the nozzle.

[0005] Furthermore, a delivery pipe is installed on one side of the nozzle, and the other end of the delivery pipe is connected to the bottom of the storage box.

[0006] Furthermore, a movable groove is provided on the top of the protective cover, a dredging structure is installed inside the movable groove, and the position of the movable groove matches the nozzle.

[0007] Furthermore, the dredging structure includes a rotating plate, which is installed inside the movable groove through a pin, a plurality of dredging teeth are installed on the top of the rotating plate, a baffle is installed on the bottom of the rotating plate, one end of the baffle is installed in the positioning plate, and the top of the positioning plate is connected and fixed to the protective cover.

[0008] Furthermore, a first fixing ring is installed above the baffle plate, a retaining spring is installed in the first fixing ring, the other end of the retaining spring is installed in a second fixing ring, the bottom of the second fixing ring is connected and fixed to the positioning plate, and one end of the baffle plate close to the positioning plate is fixedly connected to a connecting block, and the positioning plate and the connecting block are both provided with through holes corresponding to the connecting rod, and the connecting rod is inserted in the through hole to install the baffle and the positioning plate.

[0009] Furthermore, the anti-slip part includes a limit rod, four limit rods are evenly installed inside the fixed base, four limit grooves are opened on the fixed base, the limit rod is installed in the limit groove, the end of the limit rod away from the limit groove is installed with an insertion base, and the end of the insertion base away from the limit rod is installed with a buffer plate.

[0010] Furthermore, two clamping blocks are symmetrically mounted on one end of the limiting rod located inside the limiting groove, a spring is sleeved on the limiting rod, the clamping block limits the position of the spring, and the spring is located inside the limiting groove.

[0011] Furthermore, a positioning groove is formed at one end of the insertion base away from the limiting rod, and the positioning groove matches the size of the buffer sheet.

[0012] Beneficial effects of the utility model: the utility model is a graphene powder coating spraying device, in which a rotating plate is rotatably installed inside a movable groove through a latch, and a protruding block is installed on the upper part of the movable groove on the side of the rotating plate away from the latch, which limits the angle of movement of the rotating plate inside the movable groove, so that the rotating plate always remains parallel to the movable groove when returning to its original position.

[0013] A baffle is installed at the bottom of the rotating plate, and the other end of the tension spring installed on the baffle is installed on the positioning plate. The baffle and the positioning plate are installed through a connecting rod. The cross-section of the positioning plate is U-shaped. When the nozzle presses the rotating plate downward, the rotating plate will simultaneously squeeze the baffle, and the tension spring will stretch. When the nozzle is used and retracted, the tension spring will drive the baffle to retract, so that the baffle supports the bottom of the rotating plate and drives the rotating plate to return to its original position, so that the dredging teeth are always located on the outside of the protective cover. The dredging teeth are made of rubber, which is convenient for dredging before the nozzle is used to reduce blockage.

[0014] When the protective cover is installed on the inner side of the fixed base, the fixed base will squeeze the buffer sheet outward, driving the limit rod to move in the limit groove and driving the spring to retract. Because the buffer sheet is made of rubber, the thrust generated by the spring will fit with the surface of the protective cover, increasing the firmness of the installation of the protective cover and the fixed base and reducing the possibility of the protective cover moving during use.
