Description

Technical Field

[0001] The invention relates to the technical field of extrusion cooling machines, in particular to a powder coating extrusion cooling machine and a powder coating. Background Art

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Powder coating is completely different from general coatings. It exists in the form of fine powder. Since no solvent is used, it is called powder coating. The main characteristics of powder coating are: harmless, high efficiency, resource saving and environmental protection.

[0003] During the processing and production of powder coatings, different processing and production equipment are required to effectively improve the overall production efficiency. Therefore, extrusion equipment, cooling equipment, cutting equipment and screening equipment are required in the processing and production of powder coatings. During this preparation process, it is necessary to transfer many times, which consumes a lot of labor and affects the efficiency of powder coating processing and production. At the same time, when the screening equipment is screening, the materials in the screening equipment are easy to accumulate, resulting in insufficient screening of the materials, affecting the quality of screening, and during screening, the screening holes of the screening equipment are easy to be blocked, affecting the screening efficiency. When the cutting equipment is cutting, because the extruder is extruding the product, the powder coating at the center of the extrusion screen plate of the extruder is difficult to be cooled. Then, when cutting, the powder coating that has not been fully cooled is easy to stick to the knife, affecting the operation of the cutting work.

The operation of the water pump 402 and the temperature sensor 412 can be controlled by the controller 7; the connecting duct 404 is connected to the end face of the water tank 401 through a bearing seat, wherein the connection method of the connecting duct 404 and the bearing seat is a rotational connection, and the pneumatic impeller 407 is connected to the side wall of the connecting duct 404 through the bearing seat, wherein the connection method of the pneumatic impeller 407 and the bearing seat is a rotational connection. Through the interaction between the various components in the adjustable cooling structure 4, the temperature sensor 412 can operate smoothly when in use.

[0032] A method of using a powder coating extrusion cooling machine is as follows: Step 1: Pour the raw materials of the powder coating from the feed funnel (204) into the inner cavity of the extrusion fixed tube (201), and control the driving motor (205) and the heater (223) through the controller (7), so that when the driving end of the driving motor (205) rotates, the extrusion auger (206) is driven to rotate, and then the melted powder coating is extruded from the powder coating through the extrusion screen plate (203); Step 2: The water pump (402) and the temperature sensor (412) are controlled by the controller (7), and when the water pump (402) returns the cooling water in the water storage tank (401) to the water storage tank (401) through the cooling water pipe (403), the powder coating is cooled in the process; Step 3: The controller (7) controls the rotating motor (302) and the conveyor (317). When the driving end of the rotating motor (302) rotates, the driving rod (303), the driving rod (303), the driving bevel gear (304), the driven bevel gear (305) on the left, the driven bevel gear (305) on the right, the rotating rod (306), and the cutting blade (307) are rotated in sequence, and the powder coating extruded from the extrusion screen plate (203) is cut off, and the cut powder coating falls onto the conveyor (317); Step 4: The powder coating is conveyed from the guide pipe (318) to the inner cavity of the screening drum (211) by the conveyor (317). When the driven bevel gear (305) on the left side rotates, the driven rotating rod (308) and the rotating turntable (309) are driven to rotate in sequence. When the rotating turntable (309) rotates, the connecting plate (310), the connecting rotating rod (311), the connecting bearing (312), and the jet pipe (313) are driven to reciprocate up and down. The jet pipe (313), the rotating joint (314), and the guide lever (315) move reciprocatingly up and down. When the guide lever (315) moves reciprocatingly up and down, the interaction between the guide lever (315) and the spiral groove on the inner wall of the limiting guide pipe (316) allows the jet pipe (313) to move reciprocatingly up and down while driving the jet pipe (313) to rotate reciprocatingly, thereby accelerating the cooling of the powder coating in the inner cavity of the cooling box (301); Step 5: After the powder coating is cut and cooled by the cutting cooling structure (3), it is transported to the inner cavity of the screening drum (211). When the extrusion auger (206) rotates, it drives the driving pulley (207), the driving belt (208), the driven pulley (209), the driving rod (210), the screening drum (211), the annular limit plate (212), the spiral conduction plate (214) and the internal gear (215) to rotate in sequence. When the screening drum (211) is turned, qualified powder coating can be discharged from the fine material discharge port (222), and unqualified powder coating can be discharged from the filter hole of the screening drum (211) to the screening fixed pipe (202 ), when the internal gear (215) rotates, it sequentially drives the connecting gear (216) and the rotating stirring roller (217) to rotate. When the rotating stirring roller (217) rotates in the inner cavity of the screening drum (211), it can not only break up the accumulated powder coating, but also clean the filter holes on the screening drum (211), thereby preventing the filter holes of the screening drum (211) from being blocked. When the rotating stirring roller (217) rotates, it sequentially drives the driving gear (218), the driven gear (219) and the conveying auger (220) to rotate, so that the unqualified powder coating in the inner cavity of the screening fixed pipe (202) is discharged from the filter residue discharge port (221); Step 6: When the powder coating is cooled by the cooling water pipe (403), the cooling water becomes hot. At this time, the controller (7) controls the operation of the temperature sensor (412), the blower (5) and the electromagnetic control valve (6), so that the cold air is introduced from the connecting duct (404) and discharged from the blowing nozzle (411). In this process, the two sets of pneumatic impellers (407) and the rotating bevel gear (408) are driven to rotate. At the same time, under the interaction of the rotating bevel gear (408) and the fixed bevel gear (409), the connecting The duct (404), the pneumatic impeller (407), the rotating bevel gear (408), the rotating stirring blade (410) and the fixed stirring blade (406) revolve and rotate, the fixed bevel gear (409) is connected to the bottom of the inner cavity of the water storage tank (401), and the center of the pneumatic impeller (407) at the lower end is symmetrically connected to the rotating stirring blade (410) through a connecting rod. When the pneumatic impeller (407) at the lower end rotates, the rotating stirring blade (410) is driven to rotate, thereby accelerating the cooling of the cooling water in the water storage tank (401).
