[0002] At present, during the processing of powder coatings, it is sometimes necessary to stir and mix the powder coatings with other coatings. In the mixing, feeding is an indispensable link. Sometimes, according to the stirring requirements, the powder coatings need to be intermittently fed into the mixing drum in batches according to a certain feeding amount to achieve stirring and feeding at the same time to achieve a better mixing effect. However, the traditional quantitative feeding method sometimes requires workers to assist in the operation, which is not only time-consuming and labor-intensive, but also increases manual labor. In addition, since the coatings are easy to stick together and form lumps, the feeding port will be blocked during the feeding process. Therefore, those skilled in the art provide a quantitative feeding equipment for coating processing to solve the problems raised in the above background technology. Utility Model Content

It should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", and "set" should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0020] Reference Figure 1-Figure 3 A quantitative feeding equipment for paint processing includes a feeding hopper 1, a feeding port 17 is provided at the bottom of the feeding hopper 1, a guide frame 3 is fixed to the bottom outer wall of the feeding hopper 1 by bolts, and a sliding frame 4 is slidably connected to the bottom of the guide frame 3, and the sliding frame 4 is in contact with the feeding port 17 to block the feeding port 17. The shape of the sliding frame 4 is L-shaped, and a connecting port 18 is provided at the bottom of the sliding frame 4, and the connecting port 18 is connected with the feeding port 17, so that the paint can be discharged through the feeding port 17 and the connecting port 18. A driving component for reciprocating the sliding frame 4 is provided on the feeding hopper 1, so that the connecting port 18 is intermittently connected with the feeding port 17, and the paint is discharged intermittently. A puncture component is provided inside the feeding hopper 1 to prevent the paint from sticking.

[0021] In the present invention, the driving assembly includes a cam 12, a sliding rod 13, and a guide sleeve 15. The top of the hopper 1 is fixed with a cover plate 16 by bolts, and the surface of the cover plate 16 is fixed with a support seat 5 by bolts. The bottom of the support seat 5 is rotatably connected to the rotating shaft 11, and the cam 12 is keyed to the circumferential outer wall of the rotating shaft 11. The surface of the cover plate 16 is fixed with two guide sleeves 15 by bolts. The sliding rod 13 is slidably connected between the two guide sleeves 15, and one end of the sliding rod 13 is in contact with the cam 12, and the other end is fixed to the sliding frame 4. The surface of the support seat 5 is fixed with a motor 6 by bolts, and one end of the output shaft of the motor 6 is fixed to the rotating shaft 11. The circumferential outer wall of the sliding rod 13 is sleeved with a spring 14, and both ends of the spring 14 The ends are respectively fixed to the two guide sleeves 15, and the motor 6 rotates to make the rotating shaft 11 drive the cam 12 to rotate. The rotation of the cam 12 cyclically squeezes the sliding rod 13. The sliding rod 13 is squeezed and moves to one side along the guide sleeve 15. The spring 14 is forced to shrink, and the sliding rod 13 moves to drive the sliding frame 4 to move outward. The sliding frame 4 moves outward to connect the connecting port 18 with the discharge port 17. At this time, the paint is discharged through the discharge port 17 and the connecting port 18. When the cam 12 rotates to disengage from the sliding rod 13, the spring 14 rebounds and resets the sliding rod 13 to drive the sliding frame 4 to reset. The sliding frame 4 blocks the discharge port 17 again, and the paint stops flowing out. The cam 12 cyclically rotates, which can make the paint intermittently and quantitatively discharged, thereby realizing quantitative feeding.

[0022] In the present invention, the puncturing component is a plurality of cone spikes 10, and two connecting rods are fixed on the circumferential outer wall of the rotating shaft 11 by bolts. A plurality of cone spikes 10 are fixed on the two connecting rods by bolts, and the directions of the cone spikes 10 are different. The rotation of the rotating shaft 11 also drives the plurality of cone spikes 10 to rotate. The cone spikes 10 flow inside the paint, which can break up and separate the sticky and agglomerated paint, and prevent the sticky and agglomerated paint from being discharged from the discharge port 17, causing the discharge port 17 to be blocked.

[0023] In the utility model, the inner wall of the feeding hopper 1 at the bottom is fixed with a filter disc 8 by bolts, and the bottom of the rotating shaft 11 is fixed with a scraper bar 9 by bolts, and the scraper bar 9 is in contact with the surface of the filter disc 8, and the broken paint flows out through the filter disc 8, and the unfiltered and adhered paint remains on the surface of the filter disc 8. At the same time, the rotating shaft 11 rotates to rotate the scraper bar 9, and the scraper bar 9 rotates to scrape the paint on the surface of the filter disc 8, so that the paint remaining on the filter disc 8 flows, so as to avoid clogging of the filter disc 8 by the paint.

[0024] In the utility model, a conical block 2 is fixed to the bottom outer wall of the feeding hopper 1 by bolts, and the conical block 2 is located directly below the discharge port 17. The paint flowing out of the discharge port 17 falls on the surface of the conical block 2. The paint is discharged from the four sides of the conical block 2 and falls evenly into the external stirring equipment to achieve dispersed feeding of the paint.

[0025] In the present invention, mounting brackets 7 are fixed to both side outer walls of the feeding hopper 1 by bolts. The mounting brackets 7 are provided with mounting holes. The feeding hopper 1 is fixed above the mixing equipment through the mounting holes on the mounting brackets 7 .

[0026] Working principle: When it is necessary to feed the paint, the feeding hopper 1 is set above the stirring equipment, and the powder paint is poured into the feeding hopper 1, and the motor 6 is started. The motor 6 rotates to make the rotating shaft 11 drive the cam 12 to rotate, and the rotation of the cam 12 cyclically squeezes the sliding rod 13. The sliding rod 13 is squeezed and moves to one side along the guide sleeve 15. The spring 14 is forced to shrink, and the movement of the sliding rod 13 drives the sliding frame 4 to move outward. The sliding frame 4 moves outward to connect the connecting port 18 with the discharge port 17. At this time, the paint is discharged through the discharge port 17 and the connecting port 18. When the cam 12 rotates to disengage from the sliding rod 13, the spring 14 rebounds and resets, causing the sliding rod 13 to drive the sliding frame 4 to reset. The sliding frame 4 blocks the discharge port 17 again, and the paint stops flowing out. The cam 12 rotates cyclically, which can make the paint intermittently and quantitatively discharged, thereby realizing quantitative feeding.

[0027] During the rotation of the rotating shaft 11, the multiple cone thorns 10 are also driven to rotate. The cone thorns 10 flow inside the paint, which can break up and separate the adhered paint. Then the paint flows out through the filter disc 8, and the unfiltered adhered paint continues to be punctured by the cone thorns 10, thereby preventing the adhered paint from being discharged from the discharge port 17, causing the discharge port 17 to be blocked.

[0028] In this application, the structures and connection relationships that are not described in detail are all prior art, and their structures and principles are well-known technologies and will not be described in detail here.

[0029] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
