Description

Technical Field

[0001] This utility model belongs to the field of coating storage technology, and in particular to a powder coating storage device. Background Technology

[0002] Powder coating is a new type of solvent-free, 100% solid powder coating. It mainly consists of resin, curing agent, pigment, filler, and additives. During production, these raw materials undergo a series of processes including mixing, melt extrusion, cooling, pulverizing, and sieving to produce a powder with a particle size typically between 10 and 100 micrometers. It has relatively weak agglomeration resistance, and powder coatings are prone to caking due to moisture during storage, affecting their performance and quality.

[0003] A search revealed Chinese patent document (authorization announcement number CN210455895U), which relates to the field of powder coating storage technology and discloses a powder coating storage device. The device includes a tank bottom, an outer tank body fixedly installed on the top of the tank bottom, a top ring fixedly installed on the top of the outer tank body, an inner tank body fixedly installed inside the top ring, a floor mat fixedly installed on the bottom of the inner tank body, a support spring fixedly connected to the tank bottom on the bottom of the floor mat, and a threaded pipe fixedly installed on the top of the inner tank body, with a connecting pipe threaded to the outer side of the threaded pipe. This powder coating storage device has advantages such as good moisture-proof performance, solving the problem that when ordinary tanks are used to store powder coatings, gas containing moisture can enter the tank after the end cap is opened, especially in coastal areas where the air moisture content is higher, easily causing the remaining coating inside the tank to become damp and affecting the use effect of the powder coating. This device can meet basic usage requirements, but its ability to handle clumping is weak; powder coatings are prone to moisture absorption and clumping during storage, affecting the use effect and quality of the coating. Utility Model Content

[0004] The purpose of this invention is to provide a powder coating storage device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a powder coating storage device, comprising a storage tank for storing powder coating, wherein a rotating shaft is rotatably arranged inside the storage tank;

Three fixed plates for support are installed on the outer periphery of the connecting column. Two hollow columns are welded to the bottom of each of the three fixed plates. Springs are connected inside the two hollow columns. One end of the spring is connected to the fixed plate, and the other end of the spring is connected to a movable column.

[0007] Preferably, three sets of limiting plates for limiting the rotation are installed on the outer periphery of the rotating shaft, and three moving frames are connected to the side of the moving column away from the spring.

[0008] Preferably, each of the three movable frames has two pulverizing frames for pulverizing powder coatings rotatably connected inside. The pulverizing frames are equipped with limiting plates to restrict their displacement, and the movable frames are equipped with stirring blades for mixing powder coatings.

[0009] Preferably, the storage tank is equipped with a walking frame for supporting the powder coating, and the bottom of the walking frame is equipped with four casters for movement.

[0010] Preferably, a drive motor is installed inside the walking frame, and the output shaft of the drive motor is connected to the end of the rotating shaft through a coupling.

[0011] Preferably, the bottom of the storage tank is connected to a stirring hopper for stirring the powder coating, and the bottom of the stirring hopper is provided with a discharge port for discharging the powder coating.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This powder coating storage device, thanks to the structure of the crushing rack, allows the crushing rack to contact the powder coating and rotate above the limiting plate. The two crushing racks are installed alternately, crushing the clumps of powder coating, while the stirring blades agitate the powder coating. Compared to traditional powder coating storage devices with weak clump handling capabilities, this structure can improve clump handling capabilities, prevent the powder coating from becoming damp and clumping during storage, and ensure the coating's performance and quality.

[0015] This powder coating storage device benefits from the structure of the movable frame. A spring pushes the movable column downward, and the movable column drives the movable frame to move downward along the limiting plate.
