[0025] 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.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] A powder coating feeding device with recycling function mainly consists of a storage tank 1 and a screw feeding mechanism 2 forming the core framework. The storage tank 1 serves as a storage container for the powder coating, and its bottom is fixedly connected to a guide hopper 3. The guide hopper 3 has a funnel-shaped design, with a structure that is wider at the top and narrower at the bottom, which helps the powder coating to gather smoothly and be conveyed downwards. The bottom of the guide hopper 3 is connected to the inside of the screw feeding mechanism 2 through a pipe. This connection method ensures that the powder coating can smoothly transition from the storage tank 1 to the screw feeding mechanism 2, laying the foundation for subsequent conveying work. The storage tank 1 is equipped with a stirring component 4 to prevent the powder coating from clumping. The stirring component 4 inside the storage tank 1 effectively prevents the powder coating from clumping due to prolonged stillness during storage. Clumped powder coating will affect the smoothness of feeding and may even cause blockage of the feeding mechanism (screw feeding mechanism 2). The stirring component 4 of this utility model can ensure that the powder coating is always in a good flow state, ensuring the stable operation of the feeding process.

[0028] The storage hopper 1 is equipped with an annular scraper 5 inside, and the outer wall of the annular scraper 5 is in contact with the inner wall of the storage hopper 1. The top of the storage hopper 1 is equipped with a scraping component 6, which works in conjunction with the annular scraper 5 to remove and recycle the powder coating adhering to the inner wall of the storage hopper 1. The scraping component 6 is the key component for realizing the recycling of powder coating on the inner wall of the storage hopper 1. By driving the annular scraper 5 to move up and down through the scraping component 6, the powder coating adhering to the inner wall of the storage hopper 1 is scraped off, which can effectively remove and recycle the powder coating adhering to the inner wall of the storage hopper 1, greatly improve the recycling rate of powder coating, reduce powder coating waste, and reduce the production cost of enterprises.

[0029] The scraping assembly 6 includes a support frame 601, a ball screw 602, a drive motor 603, a movable plate 604, and two sets of sliding rods 605. The support frame 601 is fixedly connected to the top of the storage hopper 1. The top end of the ball screw 602 is rotatably mounted on the inner top of the support frame 601, and the bottom end of the ball screw 602 is rotatably connected to the top of the storage hopper 1. The top end of the ball screw 602 passes through the support frame 601 and is connected to the drive motor 603. The movable plate 604 is threadedly connected to the outer wall of the ball screw 602. The top ends of the two sets of sliding rods 605 are fixedly connected to the bottom of the movable plate 604, and the bottom ends of the two sets of sliding rods 605 are slidably inserted into the top of the storage hopper 1. The bottom ends of both sets of sliding rods 605 pass through the storage hopper 1 and are fixedly connected to the annular scraper 5. The drive motor 603 is fixedly installed on the top of the support frame 601. One end of the output shaft of the drive motor 603 is fixedly connected to the top of the ball screw 602. When the drive motor 603 starts, its output shaft drives the ball screw 602 to rotate synchronously. The movable plate 604 is threadedly connected to the outer wall of the ball screw 602. As the ball screw 602 rotates, the movable plate 604 will move up and down linearly along the ball screw 602. The slide bar 605 not only connects the movable plate 604 and the annular scraper 5, but also provides guidance for the up and down movement of the annular scraper 5, ensuring that the annular scraper 5 always remains in contact with the inner wall of the storage tank 1 during the movement, thereby effectively scraping off the powder coating adhering to the inner wall.

[0030] The mixing assembly 4 includes a rotating rod 401, a mixing motor 402, a mixing paddle 403, and a scraper 404. The top end of the rotating rod 401 is rotatably mounted on the inner top of the storage tank 1. The top end of the rotating rod 401 passes through the storage tank 1 and is connected to the mixing motor 402. The mixing paddle 403 is fixedly connected to the outer wall of the rotating rod 401. When the mixing motor 402 is started, it drives the rotating rod 401 to rotate. As the rotating rod 401 rotates, the mixing paddle 403 fully mixes the powder coating in the storage tank 1, keeping the powder coating in a loose state and effectively preventing the occurrence of agglomeration.

[0031] The scraper 404 is fixedly connected to the outer wall of the rotating rod 401, and the side wall of the scraper 404 is in contact with the inner wall of the guide hopper 3. During the rotation of the rotating rod 401, the scraper 404 can clean the inner wall of the guide hopper 3 and scrape off the powder coating adhering to the inner wall in time, so as to avoid the powder coating from accumulating and clogging in the guide hopper 3 and ensure the smooth conveying of the powder coating from the storage tank 1 to the screw feeding mechanism 2.

[0032] The screw feeding mechanism 2 includes a rotating shaft 201, auger blades 202, a geared motor 203, and a cylinder 204. The top of the cylinder 204 is fixedly connected to the guide hopper 3 through a pipe. The two ends of the rotating shaft 201 are rotatably mounted on the inner walls of the two sides of the cylinder 204, and one end of the rotating shaft 201 passes through the cylinder 204 and is connected to the geared motor 203. The auger blades 202 are fixedly connected to the outer wall of the rotating shaft 201. When the geared motor 203 starts, it drives the rotating shaft 201 to rotate. As the rotating shaft 201 rotates, the auger blades 202 push the powder coating that has entered the cylinder 204 forward, thereby realizing the conveying of the powder coating.

[0033] The bottom of the cylinder 204 is fixedly connected to the discharge pipe 7, which ensures that the powder coating can be accurately delivered to the spraying equipment. The outer wall of the storage tank 1 is fixedly connected to the feed pipe 8, which is used to replenish the powder coating into the storage tank 1. A sealing cap can be installed at the opening of the feed pipe 8 to prevent dust from leaking out.

[0034] Powder coating is added to storage tank 1 through feed pipe 8. Stirring motor 402 is started, driving rotating rod 401 to rotate. Stirring paddle 403 on rotating rod 401 fully stirs the powder coating in storage tank 1 to prevent powder coating from clumping. At the same time, scraper 404 cleans the inner wall of guide hopper 3 as rotating rod 401 rotates, scraping off the powder coating adhering to the inner wall to ensure smooth conveying of powder coating to screw feeding mechanism 2.

[0035] When it is necessary to recycle the powder coating adhering to the inner wall of the storage bin 1, the drive motor 603 is started. The output shaft of the drive motor 603 drives the ball screw 602 to rotate. Since the movable plate 604 is threadedly connected to the ball screw 602, and under the guidance of the two sets of slide rods 605, the movable plate 604 moves downward along the ball screw 602. The movable plate 604 drives the slide rods 605 to move downward synchronously, thereby causing the annular scraper 5 to move downward along the inner wall of the storage bin 1, scraping off the powder coating adhering to the inner wall. The scraped-off powder coating falls into the guide hopper 3 under the action of gravity.

[0036] When the geared motor 203 starts, it drives the rotating shaft 201 to rotate. The auger blades 202 on the rotating shaft 201 push the powder coating material inside the cylinder 204 forward and deliver it to the spraying equipment through the discharge pipe 7, thus completing the powder coating material feeding process.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
