Description

Technical Field

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

[0002] Powder coating is a solid powdered synthetic resin coating composed of solid resin, pigment, filler and additives. Unlike ordinary solvent-based coatings and water-based coatings, its dispersion medium is air instead of solvent and water. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption. During the production of powder coating, after uniform mixing, it is melt-mixed and extruded in a twin-screw extruder, and then extruded into sheets through double rollers. It is quickly cooled and solidified by air cooling on the surface of the conveyor belt, and finally crushed into powder.

[0003] After being extruded by the twin-screw extruder, the molten raw material falls directly into the middle position between the twin rollers and is then extruded into sheets. The molten raw material is not evenly accumulated between the two rollers, which easily leads to uneven and flat sheeting. There may even be too much material piled up and wasted from the side. Therefore, we propose a tableting device for powder coating production. Utility Model Content

[0004] The utility model aims to provide a tabletting device for powder coating production, in which a horizontal dispersion frame is arranged above a roller, and the molten raw material extruded from a bolt screw extruder enters the dispersion frame from a feed port, and under the transmission action of an auger, the molten raw material is discharged from evenly distributed ports and evenly dispersed between rollers, and then is squeezed into uniform sheets, which can also avoid leakage waste caused by excessive accumulation, thereby solving the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tableting device for powder coating production, comprising side plates and rollers, wherein two rollers are provided, and the two rollers are laterally rotatably installed at the front and rear ends between the side plates on both sides; a transverse dispersion frame is supported by a support rod above the side plates between the rollers, an auger is rotatably installed inside the dispersion frame, a plurality of through openings connected to the interior of the dispersion frame are evenly opened on the bottom surface of the dispersion frame, and a feed port connected to the interior of the dispersion frame is connected to the upper side of one side of the dispersion frame.

[0006] By adopting the above technical solution, after the device is installed above the conveyor belt, the molten material discharged from the twin-screw extruder enters the dispersion frame from the feed port, and then is evenly discharged from the through port and dispersed between the rollers through the auger transmission. It can be pressed into uniform sheets and avoid leakage and waste, which is beneficial to subsequent processing.

[0007] Optionally, an electric heating tube is embedded and fixed in the inner wall of the dispersion frame, and the electric heating tube is embedded in the dispersion frame in a spiral shape.

[0008] By adopting the above technical solution, the electric heating pipe can heat the inside of the dispersion frame to prevent the molten material from cooling and solidifying in the dispersion frame.

[0010] By adopting the above technical solution, the roller is driven to rotate by the first motor.

[0011] Optionally, a second motor is installed on the outer surface of the dispersion frame at the end of the auger, and the second motor is transmission-connected to the auger.

[0012] By adopting the above technical solution, the auger is driven by the second motor to rotate and transmit the molten material.

[0013] Optionally, a mounting plate is transversely fixed below the side edge of the side plate, and a mounting hole is provided on the surface of the mounting plate.
