Description

Technical Field

[0001] The present application relates to the technical field of powder coating processing equipment, and in particular to a powder coating storage device. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption.

[0003] Manufacturers produce powder coatings in large quantities, and the excess powder coatings will be stored in storage tanks, which will then be packaged according to market conditions. Currently, traditional storage tanks have relatively simple functions, and only serve to seal, prevent fire and moisture. However, in actual applications, it is found that when powder coatings are left in storage tanks for a long time, they are prone to agglomeration, which is not only not conducive to smooth discharge, but also has a certain impact on subsequent use. Utility Model Content

[0004] The purpose of the present application is to provide a powder coating storage device to solve at least one of the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present application provides a powder coating storage device, including a storage barrel, wherein a feed port is provided at the upper end of the storage barrel, and a discharge port and a supporting foot are provided at the lower end;

[0006] The stirring mechanism comprises a driving motor, a driving shaft, a first stirring assembly and a second stirring assembly; the driving motor is arranged at the upper end of the storage barrel, the driving shaft is arranged at the driving end of the driving motor and extends into the storage barrel, and a limit strip is formed on the outer wall of the driving shaft along its radial extension;

[0007] The first stirring assembly includes a sliding block, a first stirring paddle and a rolling element, wherein the sliding block is sleeved on the limiting strip and is formed with a limiting groove adapted to the limiting strip, the sliding block is suitable for sliding along the axial direction of the driving shaft, the first stirring paddle is fixedly connected to the sliding block, and the rolling element is arranged on a side of the first stirring paddle away from the driving shaft;

[0008] A wave-shaped guide groove is formed on the inner wall of the storage barrel, and the rolling element is slidably matched with the guide groove;

[0009] The second stirring assembly includes a second stirring paddle fixedly connected to the driving shaft;

[0010] In the above implementation process, the material to be stored is put into the storage barrel from the feed port, and then the feed port is sealed to close the storage barrel and store the powder coating; after a certain period of storage, in order to avoid the caking problem caused by long-term storage, the drive motor can be started at this time, and the drive motor drives the drive shaft to rotate. The second stirring paddle is connected to the drive shaft and follows the rotation to stir the powder coating in the storage barrel. During the rotation of the drive shaft, it drives the sliding block to rotate through the limit bar and the limit groove on the inner wall of the sliding block. The rolling element on the first stirring paddle slides with the guide groove on the inner wall of the storage barrel. During the rotation process, the guide groove prompts the first stirring paddle to also have vertical movement. In this way, the first stirring paddle not only has a rotational stirring action but also has a vertical stirring action. In combination with the second stirring paddle, the powder coating can be fully stirred, which can effectively reduce the caking problem of the powder coating stored for too long and improve the product quality.

[0011] Preferably, the first stirring paddles are provided with two and are arranged opposite to each other along the first direction;

[0012] The second stirring paddles are provided in plurality, and the plurality of second stirring paddles are arranged opposite to each other along the second direction and distributed in layers along the axial direction of the driving shaft;

[0013] The first direction and the second direction are both parallel to the radial direction of the driving shaft and perpendicular to each other.

[0014] Preferably, a fixing groove is provided at the lower end of the storage barrel, a rotating seat is provided in the fixing groove, one end of the driving shaft is rotatably provided in the rotating seat; a sealing ring is provided around the rotating seat on the inner bottom wall of the storage barrel;

[0015] In the above implementation process, the other end of the driving shaft can be rotatably arranged in the rotating seat, and the rotating seat can make the rotation of the driving shaft more stable to ensure the problem of stirring process; at the same time, by setting a sealing ring, the risk of powder coating leaking from the gap of the driving shaft can be reduced.

[0016] Preferably, the first stirring paddle comprises a frame portion and a plurality of paddle bodies disposed in the frame portion, and the plurality of paddle bodies are spaced apart and distributed in a vertical direction;

[0017] In the above implementation process, the frame body cooperates with multiple paddles to divide and form multiple spaces, so that the agglomerated powder coating can be better crushed when the powder coating is stirred; and the use of this structure allows the slurries to interact with each other, making the structure of the entire first stirring paddle more stable.

[0018] Preferably, the length direction of the paddle body is arranged at an angle with the horizontal direction, and the angle ranges from 25° to 40°;

[0019] In the above implementation process, the paddle body is tilted at a certain angle, and with its certain lifting and reciprocating motion, it can better achieve the stirring of the powder coating in the vertical direction, which is not only reflected in the better removal of blocky powder coating, but also can further mix the powder coating.

[0020] Preferably, the outer wall of the first stirring paddle and / or the second stirring paddle is provided with a sharp portion.

[0021] Preferably, the sharp portion includes a fixed column and a plurality of slices arranged on the fixed column, and the slices are arranged around the fixed column;

[0022] In the above implementation process, the sharp portion further arranged on the first stirring paddle and / or the second stirring paddle can better break up the powder coating during the stirring process, and more thoroughly treat the agglomerated powder coating. At the same time, it can also improve the stirring efficiency and enable the powder coating to reach the ideal powder state faster.

[0023] Preferably, the rolling element includes a roller or a universal ball.

[0024] Compared with the prior art, the beneficial effect of the utility model lies in that: this scheme utilizes the first stirring paddle and the second stirring paddle to cooperate with each other, wherein the first stirring paddle not only has a rotational stirring action but also has a vertical stirring action, and cooperates with the second stirring paddle to fully realize the stirring of the powder coating, which can effectively reduce the agglomeration problem of the powder coating stored for too long and improve the product quality.
