[0002] Traditional high-performance conductive materials are prepared by adding new materials inside. Specifically, a conductive agent, including conductive materials such as metal or metal oxide powder, is added to the inside of the polymer. The conductive material is added into the polymer and extruded through the extruder screw to form a high-performance conductive material. Therefore, in the field of high-performance conductive material production and processing technology, extruders are particularly widely used, and the conductive material is extruded through the extruder to complete the processing procedure.

[0003] There are various types of extruders in the prior art. For example, Chinese invention patent CN118493804A discloses a plastic extruder for cable processing, which includes a feed barrel, a feed hopper is fixedly connected to the top of the feed barrel, and an extrusion head is fixedly connected to the end away from the feed hopper. The extruder also includes a conveying mechanism, which includes an output shaft fixedly connected to the output end of the drive motor, a gear is fixedly connected to the end of the output shaft away from the drive motor, the inner wall of the feed barrel is rotatably connected to the feed shaft, the clinker shaft is a hollow shaft, and a gear ring is fixedly connected to the side wall of the end of the clinker shaft close to the drive motor, the gear ring is meshed with the gear, and a fixed spiral blade is also connected to the feed shaft. When the extruder is working, the output shaft is rotated by the drive motor, and the feed shaft can be driven to rotate by the cooperation of the gear ring and the gear, and the feed shaft can drive the fixed spiral blade to rotate to complete the extrusion operation of the material.

[0004] Although the above-mentioned extruder can realize the process of material extrusion operation, the above-mentioned extruder still has the following inconvenience in actual use.

For this reason, the present invention provides a preparation device and preparation method of high-performance static conductive material to solve the problem of material blockage and ensure the smooth production and processing of static conductive materials.

[0041] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0042] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0044] like Figure 1 as well as Figure 2 As shown, it is a structural schematic diagram of the preparation device of the high-performance electrostatic conductive material in this embodiment. The preparation device in this embodiment prepares the high-performance electrostatic conductive material by adding conductive material to the polymer material and then preparing it by mixing, melt-extruding, thereby realizing the production and processing of the material to meet the production needs.

[0045] like Figure 1 as well as Figure 2 As shown, the preparation device in this embodiment includes an extrusion mechanism 100, a feeding mechanism 200, a transmission mechanism 300 and a discharging mechanism 400. The preparation device in this embodiment includes a fixed base, on which the extrusion mechanism 100 is installed. The extrusion mechanism 100 includes an extrusion shell 101, on which the feeding mechanism 200 is installed. In this embodiment, the feeding mechanism 200 includes a feeding shell 201, which is fixedly connected to the extrusion shell 101, and the feeding shell 201 is communicated with the extrusion shell 101. In this embodiment, a transmission mechanism 300 is installed at one end of the extrusion mechanism 100, and a rotating shaft is installed in the extrusion shell 101, and the rotating shaft passes through the feeding mechanism 200 and extends into the transmission mechanism 300.

[0046] In this embodiment, a driving mechanism is fixedly installed on the fixed base, and the power end of the driving mechanism is connected to the rotating shaft. In this embodiment, the driving mechanism can drive the rotating shaft to rotate. In this embodiment, a spiral blade is installed on the rotating shaft within the extrusion mechanism 100. The driving mechanism drives the rotating shaft to rotate, and the material in the extrusion shell 101 can be mixed and pushed to achieve the purpose of extrusion.

[0047] like Figure 1 as well as Figure 2 As shown, in this embodiment, the polymer material and the conductive material enter the extrusion shell 101 through the feed shell 201. A heating mechanism is installed in the extrusion shell 101. The heating mechanism melts the polymer material and mixes it with the conductive material to prepare a high-performance electrostatic conductive material. The rotating shaft drives the spiral blades to rotate. The spiral blades follow the rotation of the rotating shaft to push the material in the extrusion shell 101 out, thereby ensuring the production and processing of the material.

[0048] like Figure 3 , Figure 4 as well as Figure 5 As shown, in this embodiment, in order to avoid material blockage at the connection between the feed shell 201 and the extrusion shell 101, a material dividing assembly is installed inside the feed shell 201. The material dividing assembly pushes the material in the feed shell 201 to both sides, and the material enters the extrusion shell 101 from both sides, thereby avoiding the problem of material blockage.

[0049] like Figures 3 to 5 As shown, in this embodiment, a rotating shaft is rotatably installed in the feed housing 201, a material dividing plate 202 is installed on the rotating shaft, and the rotating shaft passes through the feed housing 201 and enters the transmission mechanism 300, as shown in FIG.

Figure 4 As shown, in this embodiment, a driven gear 303 is also rotatably installed in the transmission housing 301, and the driven gear 303 is meshed with one of the transmission gears 302. The rotation of the driven gear 303 drives the transmission gear 302 to rotate. Due to the meshing between the transmission gears 302, the rotation of the transmission gear 302 drives the rotation shaft to rotate, and the rotation of the rotating shaft first drives the dividing plate 202 to rotate, so that the material in the feed housing 201 enters the extrusion housing 101 from both sides, avoiding material blockage and ensuring the smooth production and processing of materials.

[0050] like Figure 4As shown, in this embodiment, the rotating shaft in the extrusion shell 101 extends into the transmission shell 301, and a driving gear 304 is also connected to the rotating shaft, the driving gear 304 is located in the transmission shell 301 and meshes with the driven gear 303. In this embodiment, the driving mechanism drives the rotating shaft to rotate, and the driving gear 304 on the rotating shaft rotates with the rotating shaft and drives the driven gear 303 to rotate, which can drive the transmission gear 302 to rotate, so that the dividing plate in the feeding mechanism 200 rotates to divide the material, so that the material enters the extrusion shell 101 from both sides.

[0051] like Figure 1 , Figures 7-10 As shown, in this embodiment, a discharging mechanism 400 is also installed at the end of the extrusion mechanism 100. The materials are melted and mixed in the extrusion mechanism 100, and are discharged from the discharging mechanism 400 through the pushing of the spiral blades to complete the processing of the materials.

[0052] like Figure 7 as well as Figure 8 As shown, in this embodiment, the discharging mechanism 400 includes an outer cylinder 401 with a frustum structure and an inner cylinder 402 coaxially rotatably assembled in the outer cylinder 401. Figure 7 as well as Figure 8 As shown, in this embodiment, the outer cylinder 401 includes a rear end plate 401a and a front end plate 401b. The outer cylinder 401 is fixedly installed at the end of the extrusion shell 101. Through holes are distributed on the rear end plate 401a, so that the outer cylinder 401 is connected to the extrusion shell 101. In this embodiment, the rotation of the rotating shaft in the extrusion shell 101 drives the spiral blades to rotate, and the spiral blades squeeze the molten material into the discharge mechanism 400 through the through holes.

[0053] like Figures 7-10 As shown, in this embodiment, the expansion end of the inner cylinder 402 is open, and the molten material enters the inner cylinder 402 of the discharge mechanism 400 through the through hole.

[0054] In this embodiment, transition holes 402a are distributed on the contraction end of the inner cylinder 402, and discharge holes 401d are distributed in a ring shape on the front end plate 401b of the outer cylinder 401, and the inner diameters of the discharge holes 401d decrease successively. In this embodiment, when the transition holes 402a are aligned and connected with the discharge holes 401d, the material is extruded through the transition holes 402a and the discharge holes 401d in the inner cylinder 402.

[0055] In this embodiment, since the inner diameter of the discharge hole 401d decreases successively, when the transition hole 402a is connected with the discharge hole 401d successively, the inner diameter of the extruded material can be changed, so that materials with different particle sizes can be extruded. In this embodiment, the transition hole 402a on the inner cylinder 402 can be connected with the discharge hole 401d on the outer cylinder 401 successively by rotating the inner cylinder 402, thereby changing the inner diameter of the extruded material.

[0056] In this embodiment, Fig. 9 as well as Fig.10 As shown, in this embodiment, a guide groove 401c is further provided on the front end plate 401b of the outer cylinder 401, and the guide groove 401c is an arc-shaped structure. In addition, a locking piece 402b is installed at one end of the inner cylinder 402 close to the front end plate 401b. The locking piece 402b moves in the guide groove 401c to drive the inner cylinder 402 to rotate in the outer cylinder 401, so that the transition hole 402a is connected with the discharge hole 401d in sequence to change the inner diameter of the extruded material.

[0057] In this embodiment, the locking member 402b includes a threaded column and a nut. The threaded column extends through the guide groove 401c to the outside of the outer cylinder 401, and the nut is threadedly connected to the threaded column. In this embodiment, after the transition hole 402a is aligned with the target discharge hole 401d, the nut is screwed onto the front end plate 401b to fix the inner cylinder 402 and the outer cylinder 401, and the extrusion mechanism 100 works to extrude the material from the transition hole 402a and the discharge hole 401d.

[0058] This embodiment provides the above-mentioned preparation device on the one hand, and also provides a preparation method of high-performance conductive electrostatic material on the other hand, which specifically includes the following steps.

[0059] First, the raw materials are added into the feed shell 201 in the feed mechanism 200, and then the locking piece 402b moves along the guide groove 401c to drive the inner cylinder 402 to rotate in the outer cylinder 401, so that the transition hole 402a is aligned and connected with the target discharge hole 401d, and then the locking piece 402b fixes the inner cylinder 402 and the outer cylinder 401, and finally the driving mechanism works to drive the rotating shaft to rotate, and the rotation of the rotating shaft drives the transmission gear 302 in the transmission mechanism 300 to rotate through the driving gear 304 and the driven gear 303, and the transmission gear 302 drives the dividing plate 202 to rotate to inject the material into the extrusion mechanism 100 from both sides, and the rotating shaft in the extrusion mechanism 100 drives the spiral blade to rotate to extrude the molten material from the transition hole 402a and the discharge hole 401d.
