Description

Technical Field

[0001] This utility model relates to the field of powder coating processing technology, specifically to a feeding device for powder coating manufacturing. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resins, pigments, fillers, and additives. Unlike ordinary solvent-based and water-based coatings, their dispersion medium is air, not solvents or water. They feature solvent-free production, 100% film formation, and low energy consumption. Powder coatings are broadly classified into thermoplastic and thermosetting types. During manufacturing, powder coatings require a conveyor system to transport them to processing equipment.

[0003] Traditional feeding devices directly pour materials into the preparation equipment through the feeding port for processing. Powder coatings are prone to clumping if they are placed in a humid environment for a long time or if the storage container for powder coatings is not properly sealed. Directly injecting them into the processing equipment will reduce the quality of the powder coatings and affect their performance in the later stages of use. Therefore, we propose a feeding device for powder coating manufacturing. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model employs a second servo motor, a transmission rod, a conical filter, a semi-conical grinding block, a cleaning scraper, an elastic connecting rod, and a brush plate in a coordinated manner. During feeding, powder is poured into the feeding cylinder, where it is filtered by the conical filter inside the cylinder. This removes clumps of powder, improving powder quality. Simultaneously, the second servo motor and transmission rod drive the semi-conical grinding block and cleaning scraper to rotate back and forth, grinding the filtered powder. The cleaning scraper and the brush plate, connected by the elastic connecting rod, adhere closely to the surface of the conical filter, cleaning the powder and causing it to fall through the holes in the filter body. This breaks up clumps of powder, allowing them to be reused, preventing material waste, reducing the manufacturing cost of powder coatings, and achieving economic benefits.

[0014] 2. This utility model utilizes a first servo motor, a transmission rod, a screw rod, a second servo motor, and a feeding auger to work together. During material processing, the first servo motor drives the transmission rod to rotate, which in turn drives the screw rod fixed at the bottom of the transmission rod to rotate, thereby pushing the powder in the guide cylinder into the feeding auger. This effectively prevents blockages during feeding, ensuring smooth feeding. Furthermore, the feeding auger prevents dust from flying, effectively protecting the working environment and improving the environmental friendliness of powder coating manufacturing.

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.

[0020] Example

[0021] Please see Figure 1 - Figure 3The diagram shows a powder coating manufacturing feeding device, including a feeding cylinder 1 and a feeding auger 2. A guide pipe 3 is interconnected at the bottom of the feeding cylinder 1, and the bottom of the guide pipe 3 is interconnected with the upper end of the feeding end of the feeding auger 2. A second servo motor 9 is detachably nested at the center of the top of the feeding cylinder 1 via bolts, and the power output end of the second servo motor 9 extends through the feeding cylinder 1 to the upper end of the inner cavity of the feeding cylinder 1. A transmission rod 10 is vertically arranged at the center of the inner cavity of the feeding cylinder 1, and the top end of the transmission rod 10 is fixedly connected to the power output end of the second servo motor 9. A filter assembly 11 is provided at the lower end of the inner cavity of the feeding cylinder 1. The filter assembly 11 includes a conical filter screen 111. The outer wall of the conical filter screen 111 is detachably connected to the inner wall of the feeding cylinder 1 via bolts. A semi-conical grinding block 112 is provided inside the conical filter screen 111, and the back end of the semi-conical grinding block 112 is fixedly connected to the surface of the transmission rod 10. The inner cavity of the conical filter screen 111 and the relative... A cleaning scraper 113 is provided on one side of the semi-conical grinding block 112, and the end of the cleaning scraper 113 is fixedly connected to the surface of the transmission rod 10. The powder is filtered by the conical filter screen 111 set inside the feeding cylinder 1, thereby filtering out the powder that has agglomerated, thus improving the quality of the powder. At the same time, the second servo motor 9 and the transmission rod 10 drive the semi-conical grinding block 112 and the cleaning scraper 113 to rotate back and forth, thereby grinding the filtered powder. Meanwhile, the cleaning scraper 113 and the brush plate 115 connected to the outside by the elastic connecting rod 114 can stick tightly to the surface of the conical filter screen 111, thereby cleaning the powder on the surface of the conical filter screen 111. The powder on the surface of the conical filter screen 111 falls from the holes on its body, thereby breaking up the powder that has agglomerated and reusing it, avoiding waste of raw materials, reducing the manufacturing cost of powder coatings, and achieving economic benefits.

[0022] The cleaning scraper 113 has a detachable elastic connecting rod 114 on its outer side wall, and there are multiple elastic connecting rods 114. The outer side wall of the elastic connecting rod 114 is detachably connected to a brush plate 115 adapted to the conical filter screen 111, and the outer side wall of the brush plate 115 is attached to the inner side wall of the conical filter screen 111. The inner cavity of the guide tube 3 is provided with a spiral rod 12, and the top end of the spiral rod 12 is detachably connected to the bottom end of the transmission rod 10. During cleaning, the elastic connecting rod 114 enables the brush plate 115 to adhere tightly to the surface of the conical filter screen 111, thereby cleaning the powder on the surface of the conical filter screen 111 during rotation and avoiding waste of powder coating.

[0023] The feeding cylinder 1 has a cover 7 on both sides of its upper surface. One end of the cover 7 is equipped with a rotating connecting shaft 6, and the cover 7 is rotatably connected to one end of the upper surface of the feeding cylinder 1 through the rotating connecting shaft 6. A pull rod 8 is fixedly connected to the upper surface of the cover 7 on the side opposite to the rotating connecting shaft 6. The rotating connecting shaft 6 allows one end of the cover 7 to rotate around the rotating connecting rod, thereby facilitating the opening and closing of the feed inlet of the feeding cylinder 1. This facilitates material pouring and allows the cover 7 to be rotated to quickly seal the feed inlet of the feeding cylinder 1 after pouring, preventing dust from flying and improving the environmental friendliness of the feeding process.

[0024] The feeding auger 2 has a discharge port 5 at one bottom end. The feeding auger 2 has a first servo motor 4 in the middle of the side opposite to the discharge port 5 for driving the feeding auger 2. The second servo motor 9 and the first servo motor 4 are electrically connected to an external power supply through an external control panel. By connecting to an external power supply through the external control panel, it is convenient to supply power and can be connected to power at any time as needed, so as to cooperate with the feeding device for automatic feeding.

[0025] It should be noted that this utility model is a feeding device for powder coating manufacturing. Powder is poured into the feeding cylinder 1, and filtered by a conical filter 111 inside the feeding cylinder 1. This filters out clumps of powder, improving the quality of the powder. Simultaneously, a second servo motor 9 and a transmission rod 10 drive a semi-conical grinding block 112 and a cleaning scraper 113 to rotate back and forth, grinding the filtered powder. At the same time, the cleaning scraper 113 and the brush connected to its outer side via an elastic connecting rod 114... Plate 115 can adhere tightly to the surface of conical filter screen 111, thereby cleaning the powder on the surface of conical filter screen 111. The powder on the surface of conical filter screen 111 falls from the holes on its body to the bottom of the inner cavity of the feeding cylinder 1. The transmission rod 10 will synchronously drive the screw rod 12 fixed at the bottom to rotate, thereby pushing the powder in the guide cylinder to be conveyed into the feeding auger 2. This can effectively prevent blockage during the feeding process, ensure smooth feeding, and prevent dust from flying by using the feeding auger 2, effectively protecting the working environment and improving the environmental friendliness of powder coating manufacturing.
