[0002] Epoxy powder coatings, also known as epoxy resin powder coatings, are thermosetting, non-toxic coatings. Epoxy powder coatings are mainly composed of epoxy resin, pigments, fillers, additives, and curing agents. Among these, the curing agent is an essential additive; it enhances or controls the curing reaction, causing irreversible changes in the thermosetting resin. Epoxy powder coating melt extrusion equipment is required during the processing of epoxy powder coatings.

[0003] However, traditional epoxy powder coating melt extrusion devices still have some problems when in use. After the epoxy powder coating melt extrusion device is used, a large amount of raw material will remain on its extrusion rotating shaft. When cleaning is required, the rotating blades need to be disassembled to clean it, which makes the cleaning process more troublesome. Therefore, an epoxy powder coating melt extrusion device that is easy to clean is needed to solve the above problems. Utility Model Content

One end of the mounting bracket is fixed to one side of the mounting plate.

[0007] The above structure makes cleaning the surface of the extrusion rod more convenient during use.

[0008] Preferably, the screw has an external thread on its outer side and the sleeve has an internal thread on its inner side, forming a threaded connection between the screw and the sleeve.

[0009] The above structure, with its threaded connection, makes it more convenient to eject the extrusion rod during use.

[0010] Preferably, the inner diameter of the guide sleeve is larger than the outer diameter of the guide rod, and the guide sleeve and the guide rod form a guide structure.

[0011] With the above structure, the guide structure can make the extrusion rod more stable after it is pushed out during use.

[0012] Preferably, there are two sets of guide sleeves, which are symmetrically distributed inside the extrusion box.

[0013] Preferably, the reciprocating structure includes a servo motor, a mounting box, a lead screw, a lead sleeve, and a nozzle.

[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] This utility model embodiment provides an epoxy powder coating melt extrusion device that is easy to clean, such as... Figures 1-5 As shown, it includes an extrusion box 1 and a material box 2; a feed inlet 3 is installed on one side of the top of the extrusion box 1, and the material box 2 is fixed at the top of the feed inlet 3; an extrusion rod 9 is installed inside the extrusion box 1, and a heating column 11 is installed on the inner wall of the extrusion box 1; an installation plate 10 is installed on one side of the extrusion box 1, a drive motor 6 is installed on one side of the installation plate 10, a collection box 7 is provided on one side of the extrusion box 1, a fixing frame 8 is installed at the bottom of the extrusion box 1, a cleaning structure 4 is provided inside the fixing frame 8, and a reciprocating structure 5 is provided at the top of one side of the extrusion box 1.

[0027] In a further preferred embodiment of this utility model, such as Figures 1-5As shown: The cleaning structure 4 includes a water pipe 401, a water pump 402, a water tank 403, a screw 404, a screw sleeve 405, a guide rod 406, a mounting bracket 407, and a guide sleeve 408. The screw 404 is fixed inside the mounting bracket 8, and the screw sleeve 405 is installed on the outside of the screw 404. The guide rod 406 is fixed to both sides inside the extrusion box 1, and the guide sleeve 408 is installed on the outside of the guide rod 406. One side of the guide sleeve 408 is fixed to one side of the screw sleeve 405. On the other side, a mounting bracket 407 is fixed. One end of the mounting bracket 407 is fixed to one side of the mounting plate 10. The outer side of the screw 404 is provided with an external thread, and the inner side of the screw sleeve 405 is provided with an internal thread. The screw 404 and the screw sleeve 405 form a threaded connection. The inner diameter of the guide sleeve 408 is larger than the outer diameter of the guide rod 406. The guide sleeve 408 and the guide rod 406 form a guide structure. Two sets of guide sleeves 408 are provided. The two sets of guide sleeves 408 are symmetrically distributed inside the extrusion box 1.

[0028] Specifically, the epoxy powder coating is melted and then fed into the extrusion chamber 1 through the material box 2. After the epoxy powder coating falls into the extrusion chamber 1, the external power supply starts the heating column 11 to heat and melt the epoxy powder coating.

The threaded sleeve 504 is installed on the outside of the lead screw 503. The nozzle 505 is installed at the bottom of the threaded sleeve 504. The servo motor 501 is installed on one side of the lead screw 503. The threaded sleeve 504 is sleeved on the outside of the lead screw 503. The threaded sleeve 504 and the lead screw 503 form a threaded connection.

[0030] Specifically, when the nozzle 505 is started, the servo motor 501 is activated. After the servo motor 501 is started, it will drive the lead screw 503 to rotate. With the cooperation between the lead screw 503 and the lead sleeve 504, the nozzle 505 will move back and forth at the top of the extrusion rod 9, so that it can clean the extrusion rod 9 more effectively, thereby completing the cleaning work of the extrusion rod 9.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
