Description

Technical Field

[0001] This utility model relates to the field of melt extrusion technology, specifically to a melt extrusion device for producing powder coatings. Background Technology

[0002] Powder coatings, as a unique form of coating, are presented in the form of fine powders and belong to the category of solid coatings. They mainly encompass two categories: thermoplastic powder coatings and thermosetting powder coatings, each with its unique physical and chemical properties, suitable for different application scenarios. In the processing of powder coatings, melt extruders play a crucial role. By mixing the various components of the powder coating in a molten resin state, uniform dispersion of the components is achieved. This process effectively overcomes the component separation problem caused by differences in material specific gravity during dry mixing, thus ensuring the quality stability and consistency of the powder coating, laying a solid foundation for subsequent molding and application.

[0003] However, most melt extruders currently on the market have significant shortcomings when processing powder coatings. Typically, they rely solely on the extrusion of a screw for shaping, a single method with considerable drawbacks. Insufficient pressure results in poor shape stability of the processed products, making them prone to loosening and deformation, and difficult to store for extended periods, greatly affecting product quality and usability. Furthermore, the diameter is often not flexibly adjustable during extrusion, limiting the extruder to producing only products of specific diameters and failing to meet diverse production needs. This makes them inadequate for processing products of different specifications, severely restricting their application range and market adaptability. Therefore, there is an urgent need to develop a new type of melt extrusion equipment specifically for powder coating production, aiming to solve the aforementioned problems, improve powder coating production efficiency and product quality, meet the ever-evolving market demands, and propel the powder coating processing industry to a higher level. Utility Model Content

[0004] The purpose of this invention is to provide a melt extrusion device for producing powder coatings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A melt extrusion apparatus for producing powder coatings includes a worktable.

[0007] A linear slide rail is fixedly connected to the upper right end of the workbench. A slider is slidably connected to the top of the linear slide rail. A support platform is fixedly connected to the top of the slider. A fixing plate is fixedly connected to the top right of the support platform.

[0008] Furthermore, an electric telescopic rod is fixedly connected to the upper right end of the workbench, and one end of the electric telescopic rod is fixedly connected to the fixed plate.

[0009] Furthermore, a servo motor is fixedly connected to the top of the support platform, and a rotating shaft is fixedly connected to the output end of the servo motor.

[0010] Furthermore, a first connecting plate is fixedly connected to one end of the rotating shaft, and a second connecting plate is bolted to one end of the first connecting plate.

[0011] Furthermore, a rotating rod is fixedly connected to one end of the second connecting plate, and one end of the rotating rod passes through the extrusion chamber.

[0012] Furthermore, the left end of the extrusion chamber is bolted to a discharge plate, and the discharge plate has several discharge holes in the middle.

[0013] Furthermore, a circular limiting plate is fixedly connected to the left end of the rotating rod, and a first spiral rod is fixedly connected to the left side of the circular limiting plate.

[0014] Furthermore, a connecting rod is fixedly connected to one end of the first screw rod.

[0015] Furthermore, a plurality of crushing blades are fixedly connected to the outer surface of the connecting rod, and a second helical rod is fixedly connected to one end of the connecting rod.

[0016] Furthermore, the top of the extrusion chamber is connected to a feed pipe, and a heating chamber is opened inside the left end of the extrusion chamber, with an arc-shaped heating plate fixedly connected in the middle of the heating chamber.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In the innovative design of this utility model device, the linear slide rail, support platform, fixing plate, and electric telescopic rod play crucial roles. When the electric telescopic rod is activated, it generates a linear telescopic motion, which in turn causes the connected rotating rod to shift. The movement of the rotating rod, in turn, causes the screw rod to slide back and forth horizontally. During material conveying, this back-and-forth moving screw rod applies additional pressure to the material. Unlike the traditional method of relying solely on the rotation of the screw rod for propulsion, this pressure ensures that the material is subjected to more uniform and compact compression during the forming stage, resulting in a tighter bond between particles. This avoids the problem of loose material after forming, improves the forming quality of the material, and allows it to maintain its integrity during subsequent transportation and storage. It reduces material loss and quality degradation caused by shape collapse, providing assurance for material handling in the production process.

[0019] Meanwhile, the applicability of the device is expanded by setting up a discharge plate and discharge holes. The discharge plate has discharge holes of different specifications. When it is necessary to extrude strip materials of different diameters, the operator can change the discharge plate according to actual production needs, selecting one with discharge holes of the corresponding diameter. In this way, regardless of the diameter requirements of the production task for the strip material, the device can meet the requirements and produce products that conform to specifications, breaking the limitations of traditional equipment in terms of extrusion diameter and satisfying diverse production needs.

[0029] Please see Figure 1-4 This utility model provides a technical solution for a melt extrusion device for producing powder coatings: A melt extrusion device for producing powder coatings includes a worktable 1. A linear slide rail 2 is fixedly connected to the upper right end of the worktable 1. By setting up the linear slide rail 2, support platform 4, fixing plate 5, and electric telescopic rod 6, activating the electric telescopic rod 6 drives the rotating rod 11, causing the screw rod to move back and forth. This applies pressure during material conveying, making the material more compact and less prone to crumbling during molding, facilitating transportation and storage. A slider 3 is slidably connected to the top of the linear slide rail 2. A support platform 4 is fixedly connected to the top of block 3. A fixed plate 5 is fixedly connected to the top right of the support platform 4. An electric telescopic rod 6 is fixedly connected to the upper right of the workbench 1. One end of the electric telescopic rod 6 is fixedly connected to the fixed plate 5. A servo motor 7 is fixedly connected to the top of the support platform 4. A rotating shaft 8 is fixedly connected to the output end of the servo motor 7. A first connecting plate 9 is fixedly connected to one end of the rotating shaft 8. A second connecting plate 10 is bolted to one end of the first connecting plate 9. A rotating rod 11 is fixedly connected to one end of the second connecting plate 10. One end of the rotating rod 11 passes through the extrusion chamber 12.

[0030] The left end of the extrusion chamber 12 is bolted with a discharge plate 13. By setting the discharge plate 13 and discharge holes 14, it is easy to replace the strip materials of different diameters that need to be extruded and formed, which effectively expands the applicability of the device. Several discharge holes 14 are opened in the middle of the discharge plate 13. A circular limiting plate 15 is fixedly connected to the left end of the rotating rod 11. A first spiral rod 16 is fixedly connected to the left side of the circular limiting plate 15. A connecting rod 17 is fixedly connected to one end of the first spiral rod 16. Several crushing blades 18 are fixedly connected to the outer surface of the connecting rod 17. A second spiral rod 19 is fixedly connected to one end of the connecting rod 17.

An arc-shaped heating plate 22 is fixedly connected to the middle of the heating chamber 21.

[0031] In use, the operator adds powdered material through the feed pipe 20, and simultaneously starts the servo motor 7 and the electric telescopic rod 6. The servo motor 7 drives the rotating rod 11, causing the first spiral rod 16, the second spiral rod 19, and the crushing blade 18 to begin conveying and crushing the material to the discharge port. The heating plate then heats the material. The electric telescopic rod 6 causes the rotating rod 11 to press the second spiral rod 19 forward, rapidly extruding and shaping the material. By setting up the linear slide rail 2, support platform 4, fixing plate 5, and electric telescopic rod 6, starting the electric telescopic rod 6 drives the rotating rod 11, causing the spiral rod to move back and forth. This applies pressure during material conveying, making the material more compact and less prone to crumbling, facilitating transportation and storage. The discharge plate 13 and discharge hole 14 allow for easy replacement of strips of different diameters to be extruded, effectively expanding the applicability of the device.
