Description

Technical Field

[0001] The utility model relates to the field of coating production, in particular to a diatomaceous earth screening device for a coating production line. Background Art

[0002] Paint is a substance applied to a surface to form a complete film and firmly bond to the surface. It typically consists of a film-forming substance, pigments, fillers, solvents, and additives. Under certain conditions, it dries into a film, providing protection, decoration, or other special functions such as insulation, rust prevention, mildew resistance, and heat resistance. Diatomaceous earth, a natural material with high porosity and strong adsorption properties, is often added to paint formulations as a functional filler to improve coating properties, such as adhesion, wear resistance, and leveling. Therefore, diatomaceous earth should have an appropriate fineness to ensure uniform dispersion in the paint, and the particle size should be as consistent as possible to avoid lumps in the paint, which can affect the quality of the final product.

[0003] The prior art CN201921722092.9 includes a screening box, which is provided with a mounting assembly for fixing the screening box, a discharge channel at the bottom of the screening box, and a transport assembly for transporting diatomaceous earth connected to the discharge channel via a connecting hose. The inner cavity of the screening box is provided with a screening assembly for screening the diatomaceous earth, and a cover plate is hingedly connected to the opening of the upper end surface of the screening box, the cover plate is provided with a connecting pipe, the end of the connecting pipe is provided with a feed bin, and the cover plate is provided with a dispersion assembly; the screening assembly includes a mounting frame provided on the inner wall of the screening box, and a vibrating screen is provided on the mounting frame. Although this utility model improves the screening effect of the diatomaceous earth mixed raw material through the vibrating screen, motor 2, and stirring frame, it still has the following problems:

[0004] 1. When using the existing screen to screen the filler, the block filler will accumulate on the surface of the screen during long-term operation, which can easily cause the screening holes of the filter tool to be blocked, affecting the efficiency of raw material filtration. When the screening holes are blocked, the staff needs to clean them in time, but due to the high screening device, cleaning is difficult.

[0005] 2. During the coating production process, the raw materials need to be screened in various ways. The screening devices used for the raw materials of existing coatings are all fixed in one place. This means that after the screening is completed, the treated diatomaceous earth needs to be transferred to the next production link. This transfer process is not only time-consuming and labor-intensive, but may also cause secondary contamination or loss of materials during transportation.

[0006] 3. Due to the height and structural design of the screening device, operators may face inconvenience when adding materials, observing the screening status and maintenance, and for production environments with limited space, additional space planning may be required to install the screening device. Utility Model Content

[0007] In view of this, the purpose of the present invention is to provide a diatomaceous earth screening device for a paint production line, which solves the problems of traditional screening devices such as large space occupation and inconvenient movement through optimized design.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] Provided is a diatomaceous earth screening device for a coating production line, comprising: a production platform, a feed box, a screening mechanism, a frame, and a moving device; the feed box is arranged on the frame, and has a feed inlet at the top and a discharge outlet at the center of the bottom; the screening mechanism is arranged in the feed box;

[0010] The moving device is arranged at the bottom of the frame and can control the free movement of the frame through the moving device. A unloading platform is provided on one side above the production platform, and the upper end surface of the unloading box is not higher than the lower end surface of the unloading platform. An opening is provided on the unloading platform corresponding to the feed port on the unloading box, and the opening is covered with a flip plate; the screening mechanism includes a driving device, a vibration shaft and a screening net, the vibration shaft is supported on the side wall of the unloading box by a bearing, the screening net is fixedly mounted on the vibration shaft, and its two ends are arranged on the side wall of the unloading box by elastic parts, the vibration shaft is connected to the driving device and is driven to vibrate thereby.

[0011] It should be noted that the existing paint production platform adopts a two-layer or multi-layer structure to facilitate the feeding of raw materials into the mixing tank; therefore, the unloading platform is set on the production platform of the material feeding layer. The unloading platform can adopt the protruding part of the original production platform, or it can be a pedal installed on the edge of the production platform. The driving device of the vibration shaft can adjust the vibration frequency as needed to improve the screening efficiency; this solution uses the unloading platform to enable staff to quickly feed materials to the screening device, fully utilize the structure of the existing production platform, reduce the construction of the unloading rack required for the existing screening mechanism, reduce the purchase and modification costs of new equipment, and use the mobile device to enable the screening device to be moved after use, reducing the occupation of production space by the screening device when not in use, and the mobility of the screening device allows it to flexibly serve multiple production lines or work areas, thereby improving the utilization rate of the equipment.

[0012] Preferably, the moving device includes four universal wheels arranged at the bottom of the frame, and the universal wheels are provided with brake devices, and the brake devices can lock the wheels of the universal wheels.

[0013] It should be noted that the universal wheel allows the screening device to move freely in all directions and change direction without repositioning, so that the operator can easily push the screening device to the desired position without the need for additional mechanical equipment to assist in movement, reducing labor costs and improving work efficiency. The presence of the brake device ensures that the screening device can remain stable in the working state, avoiding operational errors or safety accidents caused by equipment movement. Therefore, this solution not only enhances the maneuverability of the screening device by arranging a universal wheel with a brake device at the bottom of the frame, but also improves the safety and convenience of operation, which plays an important role in improving the work efficiency and safety of the entire production line.

[0014] Preferably, an observation window is provided on the side of the blanking box.

[0015] It should be noted that the setting of the observation window allows the operator to directly observe the situation inside the discharge box from the outside. The operator can quickly judge whether the screening is proceeding normally, whether there is material blockage, etc., and take timely measures to adjust or troubleshoot, thereby improving screening efficiency.

[0016] Preferably, a guardrail is provided on the unloading platform, and a clamping buckle is provided on the guardrail, and the clamping buckle can clamp and fix the handle of the tool shovel.

[0017] It should be noted that the presence of the guardrail can prevent operators from accidentally falling during feeding or operation, especially on higher work platforms, the guardrail plays an important safety protection role; the design of the clamping buckle makes it easy to place and remove the tool shovel, and the operator can quickly access the tool to improve work efficiency; in the actual application of the paint production line, the tool shovel needs to be frequently used for feeding or cleaning work. When feeding the screening device, the operator can fix the tool shovel in the clamping buckle on the guardrail to ensure that the tool will not be placed randomly after the feeding is completed, thereby avoiding the safety hazards caused by the random placement of tools; when cleaning or maintaining the screening device, the tool shovel can be fixed on the guardrail for easy access at any time, and also reduces the possibility of losing the tool. Therefore, the design of setting a guardrail on the unloading platform and equipping the guardrail with a clamping buckle not only improves the safety and convenience of operation, but also promotes the standardization of on-site management.

[0018] Preferably, a hook is provided on the outer peripheral surface of the discharge port of the discharge box.

[0019] It should be noted that the design of the hook makes it easier to connect the discharge port of the feed box to the container (collecting bag), ensuring that the container will not move or tip over easily during the screening process, thereby ensuring accurate collection of materials. By connecting the conveying equipment or fixed container through the hook, the need for operators to manually support the container or equipment can be reduced, reducing the risk of personal injury during operation; by arranging a hook on the outer peripheral surface of the discharge port of the feed box, not only can the convenience and safety of the material conveying and collection process be significantly improved, but also a reliable mounting point can be provided during equipment maintenance and cleaning, thereby further improving the operating efficiency and management level of the entire production system.

[0020] Preferably, it further comprises a lifting mechanism, which comprises a fixed frame and an electric hoist, wherein the fixed frame is arranged on the unloading platform and is located on one side of the opening, and the electric hoist is arranged on the fixed frame.

[0021] It should be noted that the height and position of the fixed frame should be designed according to actual work needs to ensure that the lifting range of the electric hoist can cover the area that needs to be lifted. The use of the electric hoist can greatly improve the speed and efficiency of material lifting, which is especially suitable for heavy loads or frequent lifting occasions. By setting up a lifting mechanism (including a fixed frame and an electric hoist) on the unloading platform, it can not only greatly improve the efficiency and safety of material or equipment lifting, but also reduce the intensity of manual operation and reduce production costs.

[0022] Preferably, a ladder is provided on one side of the unloading platform, and a handrail is correspondingly provided on the ladder.

[0023] It should be noted that when operators need to frequently go up and down the unloading platform for feeding, inspection or maintenance, ladders and handrails can provide safe passages, which can not only greatly improve the safety and convenience of operators going up and down the platform, but also reduce the risk of accidents at work to a certain extent.
