Description

Technical Field

[0001] The utility model relates to the field of an extruder for processing polyester type powder coatings, in particular to an extruder for processing polyester type powder coatings. Background Art

[0002] Powder polyester coating is a coating made of amorphous resin prepared with isophthalic acid and neopentyl glycol as main monomers. It is brittle, solid and has a high glass transition temperature. The coating film is hard and tough and has a low cross-linking density. After processing, the coating needs to be extruded.

[0003] At present, when the paint is extruded, most of the existing ones are discharged directly from the discharge hole. After the discharge hole discharges the paint, it is not sealed, which makes it easy for impurities and dust in the air to enter the extrusion box through the discharge hole and pollute the paint. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide an extruder for processing polyester powder coatings to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model proposes an extruder for processing polyester powder coatings, comprising an extrusion box, a discharge hole is opened on one side of the extrusion box, a placement rack is provided on the top of the extrusion box, and a processing barrel is fixedly provided on the inner wall of the placement rack;

[0006] A sealing mechanism is provided on one side of the extrusion box, and the sealing mechanism includes a mounting plate, a rubber plug, a connecting rod and a fixed plate. A fixing plate is slidably connected to one side of the extrusion box, a connecting rod is fixedly installed on one side of the fixed plate, a mounting plate is fixedly installed on one end of the connecting rod, and a rubber plug matching the discharge hole is fixedly installed on one side of the mounting plate.

[0007] In one example, a motor is fixedly mounted on one side of the extrusion box, a rotating shaft is fixedly mounted on the output shaft of the motor, and the rotating shaft penetrates and extends into the extrusion box.

[0008] In one example, a transmission shoe is fixedly mounted on the outer ring of the rotating shaft located in the extrusion box.

[0009] In one example, a rotating rod is rotatably connected to one side of the extrusion box, and a crank is fixedly mounted on one end of the rotating rod.

[0010] In one example, an extrusion plate is fixedly mounted on the outer ring of the rotating rod, and the extrusion plate is connected to the fixed plate.

[0011] In one example, a feed pipe penetrating through and extending into the extrusion box is fixedly installed at the bottom end of the processing barrel, and a control valve is fixedly installed on the outer ring of the feed pipe.

[0012] The polyester powder coating processing extruder proposed by the utility model can bring the following beneficial effects:

[0013] 1. This polyester powder coating processing extruder moves a fixing plate to move a connecting rod, and the rubber plug can be driven to separate from the discharge hole through the mounting plate to open the discharge hole, thereby opening the discharge hole, making it easier for the extrusion box to discharge the material, and preventing impurities in the air from floating into the extrusion box through the discharge hole, thereby better protecting the coating in the extrusion box.

[0014] 2. This polyester powder coating processing extruder can drive the rotating shaft to rotate by starting the motor, and drive the transmission shoe to rotate, so that the material transported to the extrusion box by the feeding pipe can be extruded and transported to the discharge hole for discharge, thereby preventing the material from being blocked on the inner wall of the extrusion box and better discharging the material in the extrusion box.
