Abstract

This application discloses a sieving device for antibacterial and flame-retardant powder coatings, including a bottom support frame. The bottom support frame is inclined and a sieving group is arranged on it. The sieving group includes a sieving main component, a filter screen plate, and a filter screen mounting base. The filter screen plate is disposed on the sieving main component and the two are movably connected. The filter screen mounting base is disposed on both sides of the sieving main component and is installed on an inclined support plate on the bottom support frame.

Description

Technical Field

[0001] This application relates to the field of material screening technology, specifically a screening device for antibacterial and flame-retardant powder coatings. Background Technology

[0002] Powder coatings, as an environmentally friendly, high-performance coating material, are widely used in construction, home appliances, automobiles, and other fields. Among them, antibacterial and flame-retardant powder coatings, due to their excellent fire resistance and microbial inhibition capabilities, have broad application prospects in environments with high safety and hygiene requirements. However, powder coatings are prone to clumping and impurity contamination during production, transportation, and storage, severely affecting their coating quality and finished product performance. Therefore, efficient sieving before spraying to remove large particles, agglomerates, and other foreign matter, ensuring uniform powder particle size distribution, is a crucial step in improving product quality.

[0003] Currently, most common powder coating screening equipment uses a single screen structure, resulting in limited screening accuracy. Furthermore, the vibration system is often poorly designed, easily leading to material accumulation and screen clogging, thus affecting screening efficiency and continuous production capacity. In addition, most screening devices use a vibrating motor to drive the vibrating screen for material screening; however, this results in high vibration noise and poor stability during operation, easily causing structural fatigue damage with long-term use. Moreover, traditional screening equipment is typically a fixed structure, making filter replacement inconvenient, maintenance costs high, and making it difficult to adapt to the diverse screening needs of products with different particle sizes. Summary of the Invention

[0004] The technical problem to be solved by this application is to overcome the existing defects and provide a sieving device for antibacterial and flame-retardant powder coatings. By optimizing the layout of the vibrator and the structure of the screen, the sieving efficiency and equipment stability are effectively improved, and the problems of uneven sieving, high noise and high energy consumption of traditional sieving equipment are solved. This can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, this application provides the following technical solution: a sieving device for antibacterial and flame-retardant powder coatings, comprising a base support frame, the base support frame being inclined and having a sieving group mounted thereon, the sieving group comprising a sieving main body, a filter screen sieving plate, and a filter screen mounting seat, the filter screen sieving plate being mounted on the sieving main body and movably connected thereto, the filter screen mounting seat being mounted on both sides of the sieving main body and mounted on inclined support plates on the base support frame, the sieving main body also having a transition shaft on both sides, with a shaft connecting seat sleeved on the transition shaft, the shaft connecting seat being connected to the output end of a vibration drive component mounted on the base support frame, the lower end of the sieving main body also having a secondary hopper for receiving material from the material after being sieved by the filter screen sieving plate, one end of the secondary hopper being hinged to the base support frame, and the shafts on both sides of the secondary hopper being connected to shaft mounting seats on the outer side of the shaft connecting seats.

The connecting base located at the upper end is connected to the installation connecting seat located on the outside of the screening main body.

[0008] As a preferred technical solution of this application, a hopper inclined support is provided between the bottom support frames. The hopper inclined support is inclined and the secondary hopper is set on the hopper inclined support by fasteners.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0019] Please see Figure 1-4 This application provides a technical solution: a sieving device for antibacterial and flame-retardant powder coatings, including a bottom support frame 6. The bottom support frame 6 is inclined and a sieving group is provided on it. The sieving group includes a sieving main body 2, a filter screen sieving plate 1, and a filter screen mounting seat 8. The filter screen sieving plate 1 is disposed on the sieving main body 2 and the two are movably connected. The filter screen mounting seat 8 is disposed on both sides of the sieving main body 2 and is installed on the inclined support plate on the bottom support frame 6.

[0020] The bottom support frame 6 is the basic support structure of the entire screening device, which undertakes the function of fixing and bearing other components. Its upper end adopts an inclined design, which allows the powder coating to flow naturally under the action of gravity, reducing manual intervention; thus optimizing the material flow speed and screening efficiency. The screening main component 2 is used to support the filter screen plate 1 and achieves effective screening of powder coating through vibration; it is the bridge connecting the vibration drive system and the filter screen plate 1.

[0021] Specifically, the inner wall of the screening main body 2 is provided with a clamping plate 9, and a filter screen 1 is provided between the clamping plates 9 and the two are connected by fasteners.

[0022] The clamping plate 9 fixes the filter screen plate 1 to prevent it from shifting or falling off during vibration; it provides a stable clamping force to ensure a tight fit between the filter screen plate 1 and the screening main body 2; the two are connected by fasteners, which allows for easy cleaning and replacement of the filter screen plate 1 according to screening needs, improving ease of use. The filter screen plate 1 screens antibacterial and flame-retardant powder coatings, removing large particles, clumps, or foreign objects, ensuring uniform particle size of the final product and improving coating quality; the filter screen mounting base 8 provides support for the screening main body 2, and the vibration of the elastic seat 12 therein drives the screening group 1 to vibrate, thereby causing the material in the screening main body 2 to vibrate up and down, achieving material screening.

[0023] The screening main body 2 is also provided with a transition shaft on both sides, and a shaft connecting seat 11 is sleeved on the transition shaft. The shaft connecting seat 11 is connected to the output end of the vibration drive 4 provided on the bottom support frame 6.

[0024] The adapter shaft on the screening main body 2 is connected to the vibration drive 4 through the shaft connecting seat 11; the power generated by the vibration drive 4 is transmitted to the screening main body 2, causing it to vibrate regularly; and screening is performed.

[0025] Specifically, the through hole on the sleeve that connects the lower end of the shaft connecting seat 11 to the output end of the vibration drive component 4 is an eccentric hole.

[0026] The lower part of the shaft connecting seat 11 is connected to the output shaft of the vibration drive 4 through a sleeve with an eccentric hole; when the vibration drive 4 rotates, due to the eccentric effect of the shaft connecting seat 11, it drives the screening main body 2 and the secondary hopper 3 to rotate up and down, thereby realizing the vibration screening of materials.

[0027] The lower end of the screening main body 2 is also provided with a secondary hopper 3 for receiving the material after being screened by the filter screen plate 1. One end of the secondary hopper 3 is hinged to the bottom support frame 6, and the shafts on both sides of the secondary hopper 3 are also connected to the shaft mounting seat on the outside of the shaft connecting seat 11.

[0028] The secondary hopper 3 receives qualified fine powder after being screened by the filter screen plate 1; it is also equipped with a filter screen plate inside to realize secondary screening of materials and further improve the fineness of materials. The shafts on both sides can be linked with the shaft connecting seat 11 and can vibrate synchronously with the screening body 2 to prevent powder accumulation and blockage.

[0029] Furthermore, the filter screen mounting base 8 consists of a connecting base 7, an elastic seat 12, and an installation connecting seat 13. There are two connecting bases 7, which are arranged opposite each other. An elastic seat 12 is provided between the connecting bases 7. The connecting base 7 located at the upper end is connected to the installation connecting seat 13 located on the outside of the screening main body 2.

[0030] The filter screen mounting base 8 provides support for the main screening component 2, enhancing the overall structural stability. The connecting bases 7 are arranged symmetrically on the top and bottom, providing an installation foundation for the filter screen mounting base 8. The elastic seat 12 is set between the two connecting bases 7, serving to buffer vibration and absorb impact. The elastic seat 12 can provide stable support force, ensuring that the screen body vibrates along a predetermined trajectory under the action of excitation force. By adjusting the distance between the connecting bases 7 and thus the height of the elastic seat 12, the vibration characteristics of the filter screen mounting base 8 can be adjusted, and the vibration amplitude can be changed to adapt to different screening requirements.

[0031] Furthermore, a hopper inclined support 10 is provided between the bottom support frames 6. The hopper inclined support 10 is inclined. The secondary hopper 3 is set on the hopper inclined support 10 by fasteners. The hopper inclined support 10 is inclined at an angle opposite to that of the screening main body 2.

[0032] The inclined support 10 of the hopper and the inclined secondary hopper 3 are inclined in the opposite direction to the screening main body 2, which can compensate for the spatial deviation caused by the inclination and ensure the good balance of the material collection device.

[0033] Furthermore, the shaft mounting base includes a movable retainer 14 and a positioning seat 15. The movable retainer 14 and the positioning seat 15 are mounted on the shaft connecting seat 11 by fasteners. The through hole on the movable retainer 14 is sleeved with the mounting shafts located on both sides of the secondary hopper 3.

[0034] The shaft mounting base is a structure used to support or connect rotating parts; it consists of a movable clamp 14 and a positioning seat 15, wherein the movable clamp 14 and the positioning seat 15 are arc-shaped structures used to fix it on the shaft connecting seat 11. The movable clamp 14 is sleeved with the mounting shafts on both sides of the secondary hopper 3 to transmit the vibration of the vibration drive 4, thereby further realizing material screening.

[0035] Furthermore, an intermediate cross brace 5 is provided between the bottom support frames 6, and the vibration drive component 4 is disposed on the upper surface of the intermediate cross brace 5.

[0036] In use: The secondary hopper 3 is fastened to the inclined hopper support 10 and tilted in the opposite direction to the screening main body 2 to ensure smooth discharge. The shaft mounting seat is installed on the shaft connecting seat 11 and is well connected to the mounting shafts on both sides of the secondary hopper 3. The antibacterial and flame-retardant powder coating is added to the screening main body 2 from above. Under the action of gravity, the material slides naturally down the inclined bottom support 6 onto the filter screen plate 1. The vibration drive 4 is activated, and its output end drives the shaft connecting seat 11 to move through the sleeve with an eccentric hole. The rotational power generated by the vibration drive 4 is converted into up-and-down reciprocating motion, which drives the screening main body 2 and the secondary hopper 3 to produce regular motion. The filter screen 1 performs preliminary screening of the powder coating under the action of vibration, removing large particles, lumps, or foreign objects to ensure uniform particle size. The qualified fine powder after the initial screening falls into the secondary hopper 3 below. The secondary hopper 3 is equipped with a second layer of filter screen plate to achieve secondary fine screening of materials and further improve product quality. Since the secondary hopper 3 and the screening main body 2 vibrate synchronously, powder accumulation and blockage can be effectively prevented, and screening efficiency can be improved. The finished powder after screening is discharged through the bottom outlet of the secondary hopper 3 and enters the subsequent processing steps. The residual materials inside the secondary hopper 3 are cleaned in time to keep it clean and avoid cross-contamination, thus completing the material screening.

[0037] If it is necessary to adjust the amplitude or screening effect, the distance between the two connecting bases 7 in the filter screen mounting seat 8 can be adjusted to change the compression of the elastic seat 12, thereby optimizing the vibration parameters.

[0038] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
