Abstract
Description
Technical Field
[0001] This utility model belongs to the field of antistatic powder coating technology, and in particular relates to an antistatic powder coating dispersion and discharge device. Background Technology
[0002] Antistatic powder coatings are special functional coatings designed to reduce or prevent the accumulation of static electricity. They are widely used in the surface treatment of various industrial and consumer products that require antistatic protection. These coatings impart a certain degree of conductivity to the coating by adding conductive materials, such as metal powder, conductive carbon black, or other additives with conductive properties, to the traditional powder coating formulation. This effectively disperses and dissipates static charges, avoiding potential hazards caused by static electricity, such as dust adsorption and spark discharge.
[0003] Existing antistatic powder coatings lack a dispersion and discharge device that can prevent agglomeration and dust leakage. The problem with the above technology is that, in practical applications, current antistatic powder coatings lack an effective dispersion and discharge device to prevent agglomeration and dust leakage. This not only limits their efficiency but may also affect the quality of the final product and the safety of the operating environment. Due to their special composition, antistatic powder coatings are prone to agglomeration during storage or handling, which directly affects the uniform dispersion and application performance of the coating. In addition, without effective sealing measures during feeding and discharging, dust leakage is very likely to occur, wasting materials, polluting the working environment, and potentially adversely affecting the health of operators.

[0005] This utility model is implemented as follows: an antistatic powder coating dispersion and discharge device includes a support column, a processing box, a discharge pipe, a servo motor, and a feeding plate.

[0007] The auxiliary mechanism is used to prevent dust from escaping.
[0008] To improve the screening effect, preferably, the stirring device includes a support rod, a connecting block, a mounting block, an elastic block, a brush plate, a fixing plate, a stirring plate, and a sliding plate.

The lower surface of the support frame is fixedly connected to the upper surface of the feed plate. The sieve plate ensures that the antistatic powder coating can be preliminarily screened before entering the processing box, so as to effectively remove lumps and impurities. This ensures that only powder coatings that meet the requirements can enter the processing box for further processing, which not only improves the purity of the product, but also reduces the risk of failure in subsequent processes.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This invention comprises a stirring device, an auxiliary mechanism, a mounting block, an elastic block, a brush plate, a fixed plate, a stirring plate, a movable rod, a sliding rod, a spring, a limiting plate, a baffle, and a guide ring.

The stirring device 1 includes a support rod 101, a connecting block 102, a mounting block 103, an elastic block 104, a brush plate 105, a fixing plate 106, and a stirring arm.

The middle surface of the baffle 206 is fixedly connected to the surface of the guide ring 207, ensuring that the limiting plate 205 can move smoothly along the sliding rod 203, thus providing stability to the movement of the limiting plate 205.

The surface of the guide ring 207 is rotatably connected to the surface of the support frame 4, and the lower surface of the guide ring 207 is rotatably connected to the upper surface of the feed plate 9. The surface of the servo motor 8 is fixedly connected to the inner surface of the support frame 4, and the lower surface of the baffle 206 slides in contact with the upper surface of the feed plate 9, ensuring that the guide ring 207 can rotate smoothly during operation. This not only provides the necessary flexibility, allowing the baffle 206 to smoothly open and close the feed inlet, but also ensures the stability of the guide ring 207 during rotation, reducing operational malfunctions caused by displacement.
[0024] The working principle of this utility model:
[0025] In the production process of antistatic powder coating, the first step is to pull the movable rod 201 inside the support block 202. When the movable rod 201 is pulled, the limiting plate 205 located at the lower end of the movable plate moves along the surface of the sliding rod 203 and is pulled out from the inner wall of the baffle 206. After this step, the baffle 206 can be rotated to open the feed port so that the antistatic powder coating can be poured into the processing box 6. The coating will then fall onto the sieve plate 3 on the upper part of the processing box 6. To ensure that the coating can pass through the sieve plate 3 evenly, the servo motor 8 should be started next. The output shaft of the servo motor 8 is connected to the support rod 101 and drives it to rotate. The mounting block 103 installed above the support rod 101 moves accordingly, so that the brush plate 105 can slide smoothly on the surface of the sieve plate 3 and come into contact with the antistatic powder coating. This process not only helps the coating to fall through the sieve plate 3 into the processing box 6, but also, due to the function of the sieve plate 3, it can effectively prevent lumps or impurities from entering the processing box 6, ensuring the purity of the product. It is worth mentioning that the brush plate 105 The equipped elastic block 104 can automatically adjust the distance between the brush plate 105 and the sieve plate 3 according to the actual situation to optimize the screening effect. Once the antistatic powder coating falls into the treatment box 6, the antistatic powder coating will be stirred with the help of the stirring plate 107. The stirring plate 107 is fixed below the support rod 101 and moves with the rotation of the support rod 101, which can effectively prevent the coating from agglomerating in the treatment box 6 and maintain good fluidity. After adding the antistatic powder coating, the baffle 206 needs to be rotated back to the initial position so that one end is tightly attached to the surface of the support block 202, and the movable rod 201 is pushed so that the limiting plate 205 is reinserted into the inner wall of the baffle 206. The spring 204 on the limiting plate 205 can ensure that the baffle 206 and the support block 202 are in close contact to prevent external impurities from entering the treatment box 6, thereby protecting the coating from contamination. When it is necessary to remove the treated antistatic powder coating, simply connect the discharge pipe to the discharge pipe 7 at the bottom of the treatment box 6 to discharge the product smoothly, which is convenient for subsequent packaging and use.
