Description

Technical Field

[0001] This utility model relates to the field of fine powder technology for pure polyester weather-resistant powder, and in particular to a fine powder device for pure polyester weather-resistant powder coating. Background Technology

[0002] Pure polyester weather-resistant powder coating is a powder coating made primarily of pure polyester resin as the film-forming substance, exhibiting excellent weather resistance. Its main characteristics include the ability to maintain the gloss and color of the coating film over a long period in outdoor environments, and outstanding resistance to ultraviolet radiation and harsh weather conditions. Therefore, it is widely used for coating outdoor facilities. To achieve better adhesion during electrostatic spraying and to form a smooth, flawless coating, a fine powder processing device for pure polyester weather-resistant powder coating is required.

[0003] Fine powder equipment for pure polyester weather-resistant powder coatings can be divided into several types, namely mechanical screening fine powder equipment, air classifier fine powder equipment, and grinding fine powder equipment. Selecting the appropriate type of fine powder equipment according to production needs and technical requirements is crucial to the quality of pure polyester weather-resistant powder coatings. Among them, grinding fine powder equipment uses mechanical grinding devices (such as ball mills and sand mills) to crush and refine powder particles.

[0004] Existing fine powder grinding equipment is prone to incomplete grinding during the grinding process. Because the raw materials are not sufficiently dispersed during grinding, some materials remain as large particles, affecting the fineness and uniformity of the final powder. This is especially true when processing difficult-to-grind materials such as polyester powder; traditional grinding equipment cannot adequately crush large particles into uniform, fine particles, thus reducing grinding efficiency and potentially affecting the quality of the coating. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fine powder device for pure polyester weather-resistant powder coating, which aims to improve the problem that the fine powder device is prone to insufficient grinding during grinding.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fine powder device for pure polyester weather-resistant powder coating, comprising a frame, a drive assembly inside the frame, a grinding cylinder fixedly connected to one side of the frame, a support column fixedly connected inside the frame, a baffle fixedly connected to one end of the support column, a connecting cylinder rotatably connected to the outer wall of the baffle, a transmission assembly on the outer wall of the connecting cylinder, a grinding assembly on the outer wall of the connecting cylinder, an agitation assembly at one end of the connecting cylinder, and a feeding hopper fixedly connected inside the frame;

[0007] The grinding assembly includes a grinding head, which is fixedly connected to the outer wall of the connecting cylinder. Both the grinding head and the connecting cylinder have through holes, and the outer wall of the grinding head is attached to the inner wall of the grinding cylinder.

[0008] As a further description of the above technical solution:

[0009] The agitation assembly includes a connecting shaft, one end of which is fixedly connected to one end of a connecting cylinder, and an agitation rod is fixedly connected to the outside of the connecting shaft.

[0010] As a further description of the above technical solution:

[0011] The drive assembly includes a motor, the outer wall of which is fixedly connected to the inside of the frame, and a gear is fixedly connected to the output end of the motor.

[0012] As a further description of the above technical solution:

[0013] The transmission assembly includes a gear ring, which is fixedly connected to the outer wall of the connecting cylinder, and the connecting cylinder meshes with a gear.

[0014] As a further description of the above technical solution:

[0015] A sleeve is rotatably connected inside the baffle one, a sieve cylinder is fixedly connected to one end of the sleeve, a baffle two is fixedly connected inside the connecting cylinder, and a scraper is fixedly connected to the outer wall of the sieve cylinder.

[0016] As a further description of the above technical solution:

[0017] One side of the baffle is rotatably connected to a connecting block one, and the outer wall of the sleeve is rotatably connected to a connecting block two.

[0018] As a further description of the above technical solution:

[0019] A telescopic rod is provided on one side of the baffle, and a tension spring is sleeved on the outer wall of the telescopic rod.

[0020] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the raw material inside the connecting cylinder is first discharged through the through hole and ground between the grinding head and the grinding cylinder. The ground raw material drives the connecting shaft to rotate through the connecting cylinder. The connecting shaft stirs and disperses the ground raw material through the stirring rod, thereby improving the degree of grinding. This solves the problem that the fine powder device is prone to insufficient grinding during grinding and improves the grinding efficiency of the fine powder device.

[0024] 2. In this utility model, the inner wall of the connecting cylinder contacts the scraper on the outer wall of the screen cylinder through the baffle, so that the screen cylinder can rotate a certain angle.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 This utility model provides an embodiment of a fine powder device for pure polyester weather-resistant powder coatings, comprising a frame 1, with a drive assembly inside the frame 1 providing power to drive the entire device. A grinding cylinder 7 is fixedly connected to one side of the frame 1. The grinding cylinder 7 contains and surrounds the raw materials during the grinding process, providing support and protection to ensure the flowability and uniformity of the raw materials. A support column 4 is fixedly connected inside the frame 1, supporting the various components of the device and ensuring the stability and durability of the entire fine powder device, preventing vibration or displacement. A baffle 5 is fixedly connected to one end of the support column 4, controlling the flow direction of the raw materials and preventing excessive flow into the grinding area, ensuring uniform distribution during the grinding process. A connecting cylinder 9 is rotatably connected to the outer wall of the baffle 5. As a key component for raw material conveying and grinding, the connecting cylinder 9's outer wall contacts the grinding assembly through rotation, thereby completing the dispersal and refinement of the raw materials. A transmission assembly is installed on the outer wall of the connecting cylinder 9. This assembly transmits driving force through the cooperation of gear 3 and gear ring 8, enabling the connecting cylinder 9 to rotate smoothly. A grinding assembly, including a grinding head 10, is installed on the outer wall of the connecting cylinder 9. The grinding head 10 is fixedly connected to the outer wall of the connecting cylinder 9, performing physical grinding of the raw materials to ensure they are sufficiently refined. Both the grinding head 10 and the connecting cylinder 9 have through holes 11, which allow the raw materials to flow and be ground, ensuring uniform processing during the grinding process. The outer wall of the grinding head 10 is fitted against the inner wall of the grinding cylinder 7, ensuring full contact and improving grinding efficiency. A stirring assembly includes a connecting shaft 12, one end of which is fixedly connected to one end of the connecting cylinder 9. The connecting shaft 12, through a stirring rod 13, further enhances the stirring effect of the raw materials, ensuring uniform distribution and preventing material accumulation during grinding. A drive assembly includes a motor 2, the outer wall of which is fixedly connected to the inside of the frame 1. The motor 2 provides power to drive the entire device. A gear 3 is fixedly connected to the output end of motor 2. The gear 3 meshes with the gear ring 8. The gear ring 8 is fixedly connected to the outer wall of the connecting cylinder 9 to form a transmission system, ensuring that the connecting cylinder 9 can operate efficiently to complete the grinding and processing of raw materials.

[0033] Specifically, the raw material first enters the internal space of the connecting cylinder 9 through the feeding hopper 6, beginning the processing flow. Subsequently, the output end of the motor 2 drives the gear 3 to rotate, and the gear 3 transmits the rotational power to the connecting cylinder 9 through the gear ring 8, causing the connecting cylinder 9 to rotate accordingly. The rotation of the connecting cylinder 9 further drives the rotation of the grinding head 10, causing the outer wall of the grinding head 10 to fit tightly against the inner wall of the grinding cylinder 7, forming a highly efficient grinding contact surface. At this time, the raw material inside the connecting cylinder 9 is evenly discharged through the through hole 11 set inside the cylinder, entering the grinding area between the grinding head 10 and the grinding cylinder 7. During this process, the raw material is continuously refined and ground under strong friction, making the particles more uniform and fine. After preliminary grinding, the raw material is then driven by the rotation of the connecting cylinder 9, pushing the connecting shaft 12 to rotate synchronously. The connecting shaft 12, through the stirring rod 13 fixed on it, further stirs and disperses the ground raw material, ensuring that the material does not settle or clump during the grinding process, resulting in a more uniform and thorough grinding effect.

[0034] Reference Figure 3 and Figure 4A sleeve 14 is rotatably connected inside the baffle 5. The sleeve 14 provides flexible rotation, allowing the connected screen cylinder 15 to be adjusted in angle as needed, thus ensuring that the screen cylinder 15 can adapt to different operating requirements during use. The screen cylinder 15 is fixedly connected to one end of the sleeve 14. The screen cylinder 15's function is to screen the raw materials, removing unsuitable particles to ensure the uniformity and fineness of the raw materials during grinding. A baffle 16 is fixedly connected inside the connecting cylinder 9. The baffle 16 restricts the flow direction of the raw materials, ensuring that the raw materials flow along a predetermined trajectory inside the equipment, thereby improving work efficiency and preventing blockages. A scraper 17 is fixedly connected to the outer wall of the screen cylinder 15. The scraper 17 scrapes off material adhering to the surface of the screen cylinder 15, preventing material accumulation on the surface of the screen cylinder 15 from affecting the screening effect, while also improving screening speed and efficiency. A connecting block 18 is rotatably connected to one side of baffle 5. Connecting block 18 connects and secures other parts of the equipment, ensuring a stable connection between the screen cylinder 15 and other components, enabling the entire structure to work collaboratively and maintaining equipment stability. A connecting block 29 is rotatably connected to the outer wall of sleeve 14. Connecting block 219 cooperates with connecting block 18 to ensure synchronous movement of all components and optimizes working efficiency by adjusting relative angles. A telescopic rod 20 is provided on one side of baffle 5. The telescopic rod 20 adjusts the distance between components through extension and retraction, ensuring the entire device can adapt to different working requirements. A tension spring 21 is fitted onto the outer wall of the telescopic rod 20. The tension spring 21 provides restoring force, ensuring the telescopic rod 20 automatically springs back to a predetermined position after being subjected to force. One end of the telescopic rod 20 and the tension spring 21 are both fixedly connected to one side of the connecting block 18, and the other end of the telescopic rod 20 and the tension spring 21 are both fixedly connected to one side of the connecting block 29. With this design, the telescopic rod 20 can maintain stability under the action of the tension spring 21 and ensure that all parts of the equipment can work together during operation.

[0035] Specifically, when the raw material is fed into the connecting cylinder 9 through the feeding hopper 6, it is first uniformly guided into the screen cylinder 15 to ensure its smooth entry into the next processing stage. When the connecting cylinder 9 begins to rotate, its inner wall contacts the scraper 17 on the outer wall of the screen cylinder 15 via a baffle 16. With the help of the scraper 17, the screen cylinder 15 smoothly follows the connecting cylinder 9 to rotate at a certain angle. This rotation uniformly agitates the material in the screen cylinder 15, effectively preventing sedimentation or clumping and ensuring smooth material processing. Subsequently, the screen cylinder 15, through its cooperation with the sleeve 14, is stably restrained in a designated position, preventing excessive deviation or shaking. Simultaneously, the telescopic rod 20 further limits the screen cylinder 15 through its tension, ensuring it remains in a suitable working state. This series of designs and actions allows the raw material to be fully dispersed within the screen cylinder 15 and effectively filtered or graded, achieving the effect of material dispersion and improving the efficiency and accuracy of subsequent processing.

[0036] Working principle: When using this fine powder device for pure polyester weather-resistant powder coating, the raw material is first fed into the connecting cylinder 9 through the feeding hopper 6. Then, the output end of the motor 2 drives the gear 3 to rotate. The gear 3 drives the connecting cylinder 9 to rotate through the gear ring 8. The connecting cylinder 9 drives the grinding head 10 to rotate. The outer wall of the grinding head 10 is attached to the inner wall of the grinding cylinder 7. The raw material inside the connecting cylinder 9 is discharged through the through hole 11 and ground between the grinding head 10 and the grinding cylinder 7. The ground raw material drives the connecting shaft 12 to rotate through the connecting cylinder 9. 2. The grinding of the raw material is agitated by the stirring rod 13, which improves the degree of grinding. When the raw material is fed into the connecting cylinder 9 through the feeding hopper 6, it will first be fed into the screen cylinder 15. When the connecting cylinder 9 rotates, the inner wall of the connecting cylinder 9 contacts the scraper 17 on the outer wall of the screen cylinder 15 through the baffle 2 16, so that the screen cylinder 15 can rotate with it at a certain angle. Then the screen cylinder 15 is limited in the baffle 1 5 by the sleeve 14, and the screen cylinder 15 is limited by the pulling force of the telescopic rod 20, which achieves the effect of dispersing the raw material.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
