[0001] The utility model relates to the technical field of powder coating production equipment, in particular to a powder coating crushing device. Background Art

[0002] Powder coating is a solid powder synthetic resin coating composed of solid resin, pigments, fillers, and additives. Different from 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. During the production process of powder coating, crushing work is required.

[0003] For example, the publication number is CN211964429U, and on November 20, 2020, an improved powder coating fine crushing device was disclosed, which specifically relates to the field of powder coating processing equipment, including a machine shell. Feeding hoppers are connected to both outer side walls of the machine shell. A wire rack is installed above the discharge port of the feeding hopper inside the machine shell. Springs are connected to the four corner positions at the bottom end of the wire rack. A metal filter screen is arranged inside the wire rack. A limiting ring is arranged corresponding to the outside of the stirring shaft in the middle of the metal filter screen. A vibration mechanism is installed above the metal filter screen inside the machine shell. When the above-mentioned disclosed crushing device is in use, the uniform feeding of powder coating cannot be achieved, and the powder coating is prone to blockage during the feeding process, resulting in the inability of the powder coating to be stably crushed in the crushing device.

Specific implementation mode

[0020] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0021] The following details the specific implementation of the present utility model in conjunction with specific embodiments.

[0022] As Figures 1-3 shown, a powder coating crushing device includes a frame body 1. It is characterized in that a grinding cylinder 2 is provided on the frame body 1, and a grinding assembly for grinding powder coating is provided in the grinding cylinder 2. The grinding assembly grinds the powder coating entering the grinding cylinder 2, and a uniform feeding assembly is provided on the grinding cylinder 2 to realize the uniform feeding of the powder coating into the grinding cylinder 2.

[0023] During use, the raw material of the powder coating enters the grinding cylinder 2 through the uniform feeding assembly, and the grinding assembly in the grinding cylinder 2 crushes the powder coating. The uniform feeding assembly prevents the powder coating from being blocked during the feeding process, thereby ensuring the stable grinding work of the powder coating in the grinding cylinder 2.

[0024] Specifically, the uniform feeding assembly includes a feed seat 14 communicated with the grinding cylinder 2. A material distributing plate 19 is provided in the feed seat 14. An air inlet hole 16 connected to an external air source is provided on the feed seat 14. A driving mechanism for driving the material distributing plate 19 to rotate is also provided on the feed seat 14. The driving mechanism rotates the material distributing plate 19, so that the powder coating falling on the feed seat 14 falls evenly. Furthermore, under the pressure of the external air source, gas enters the feed seat 14 through the air inlet hole 16, and the gas drives the powder coating to enter the grinding cylinder 2 communicated with the feed seat 14.

[0025] Refer to Figure 1 and 3, the driving mechanism includes a third motor 20 arranged outside the feeding base 14. A rotating shaft 17 is provided inside the feeding base 14. A rotating roller 18 is provided on the rotating shaft 17. The distributing plates 19 are symmetrically arranged on the rotating roller 18. The power output shaft of the third motor 20 is connected to the rotating shaft 17 through a speed reducer 21. In this embodiment, there are six distributing plates 19, and the six distributing plates 19 are symmetrically welded to the outer wall of the rotating roller 18. Further, when the third motor 20 works, the speed reducer 21 drives the rotating shaft 17 to rotate. The rotation of the rotating shaft 17 causes the rotating roller 18 to drive the six distributing plates 19 to rotate, so as to evenly drop the powder coating falling into the feeding base 14 to the lower side of the feeding base 14, and then it is convenient for the high-speed gas in the lower air inlet hole 16 to transport the powder coating to the grinding cylinder 2 for grinding work.

[0026] The feeding base 14 is communicated with the grinding cylinder 2 through a feeding pipe 24. Thus, the powder coating in the feeding base 14 enters the grinding cylinder 2 through the feeding pipe 24. A funnel 15 is provided on the feeding base 14 to facilitate the powder coating to enter the feeding base 14 through the funnel 15. In this embodiment, the funnel 15 is welded to the feeding base 14.

[0027] The grinding assembly includes a grinding frame 6 arranged in the grinding cylinder 2. A first connecting shaft 12 connected to the grinding frame 6 is provided inside the grinding cylinder 2. The first connecting shaft 12 is connected to the grinding cylinder 2. One end of the first connecting shaft 12 extends outside the grinding cylinder 2. A first motor 8 is provided on the frame body 1. A driving pulley 9 is provided on the power output shaft of the first motor 8. A driven pulley 11 is provided on the first connecting shaft 12. The driving pulley 9 is connected to the driven pulley 11 through a belt 10. When the first motor 8 works, the driving pulley 9 rotates. The rotation of the driving pulley 9 causes the belt 10 to drive the driven pulley 11 to rotate. The rotation of the driven pulley 11 causes the first connecting shaft 12 to rotate. The rotation of the first connecting shaft 12 causes the grinding frame 6 to rotate, and then the powder coating entering the grinding cylinder 2 is ground.

[0028] A scraper 7 is provided on the grinding frame 6. The powder coating on the lower side of the grinding cylinder 2 is scraped onto the grinding frame 6 by the scraper 7, so as to facilitate the stable crushing work of the powder coating.

[0029] A cover plate 3 is provided on the grinding cylinder 2. A vertical cylinder 4 is provided on the cover plate 3. A discharge pipe 5 is provided on the vertical cylinder 4. The discharge pipe 5 is externally connected to a negative pressure source. Thus, the gas drives the crushed powder coating to be discharged from the discharge pipe 5 on the vertical cylinder 4. In this embodiment, one end of the cover plate 3 is hinged to the grinding cylinder 2. The cover plate 3 is connected to the grinding cylinder 2 through a buckle. The vertical cylinder 4 is communicated with the grinding cylinder 2.

[0030] A second motor 13 is provided on the vertical cylinder 4. A second connecting shaft 22 is provided on the power output shaft of the second motor 13. One end of the second connecting shaft 22 extends into the vertical cylinder 4. A blade 23 is provided on the second connecting shaft 22. When the second motor 13 operates, the second connecting shaft 22 rotates. The rotation of the second connecting shaft 22 causes the blade 23 to rotate. The rotation of the blade 23 further crushes the powder coating, so as to ensure that the powder coating discharged from the discharge pipe 5 meets the requirements. In this embodiment, the second motor 13 is installed on the upper side of the vertical cylinder 4 by bolts. The second connecting shaft 22 is vertically arranged, and the discharge pipe 5 is arranged on the upper side of the blade 23.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
