Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] As shown in Figure 1 , Figure 5 and Figure 6 , the utility model provides a kind of technical scheme of extrusion mechanism for thermosetting plastic powder production, including extrusion main body shell 1, extrusion main body shell 1 is communicated with stirring barrel 15, the position arrangement between extrusion main body shell 1 and stirring barrel 15, it is guaranteed that thermosetting plastic powder can smoothly enter extrusion main body shell 1, the top of stirring barrel 15 is fixedly connected with one-way motor three 16, the output shaft of one-way motor three 16 is fixedly connected with linkage rod two 17, the setting of one-way motor three 16, the rotation of linkage rod two 17 can be effectively provided with sufficient power support, one-way motor three 16 is prior art.

[0025] As shown in Figure 5 and Figure 6As shown, the outer circumferential surface of linkage rod two 17 is fixedly connected with stirring rod 18, and there are five stirring rods 18. The linkage rod two 17 and the stirring rod 18 keep the linkage effect. The setting of the stirring rod 18 can effectively stir the thermosetting plastic powder, thereby accelerating the melting and mixing of the thermosetting plastic powder. The outer circumferential surface of the stirring barrel 15 is fixedly connected with a heating sheet 19. The setting of the heating sheet 19 can effectively heat the internal space of the stirring barrel 15, thereby ensuring the melting of the thermosetting plastic powder. The heating sheet 19 is a prior art.

[0026] As shown in Figure 1 , Figure 5 and Figure 6 , the other end of the extrusion main shell 1 is fixedly connected with a one-way motor two 12. The output shaft of the one-way motor two 12 is fixedly connected with a linkage rod one 13. The setting of the one-way motor two 12 can effectively provide sufficient power support for the rotation of the linkage rod one 13. The one-way motor two 12 is a prior art. The outer circumferential surface of the linkage rod one 13 is fixedly connected with a propelling blade 14. The linkage rod one 13 and the propelling blade 14 keep the linkage effect. The setting of the propelling blade 14 can effectively push the melted thermosetting plastic powder forward, so that the thermosetting plastic powder is discharged from the extrusion head 2. One end of the extrusion main shell 1 is sleeved with the extrusion head 2. The setting of the extrusion head 2 ensures the shape of the melted thermosetting plastic powder. The extrusion head 2 can be replaced, thereby changing the shape of the discharge.

[0027] As shown in Figure 1 and Figure 2 , the outer circumferential surface of the extrusion main shell 1 is fixedly connected with a position control installation shell 3. The position control installation shell 3 is fixedly connected with a one-way motor one 5 through a support plate 4. The setting of the support plate 4 can effectively ensure that the one-way motor one 5 stably works. The output shaft of the one-way motor one 5 is fixedly connected with a plane gear 6. The setting of the one-way motor one 5 can effectively provide sufficient power support for the rotation of the plane gear 6. The one-way motor one 5 is a prior art.

[0028] As shown in Figure 2 and Figure 4 , the teeth on the outer circumferential surface of the plane gear 6 are engaged with the teeth on the outer circumferential surface of the position control toothed disc 7. The close cooperation between the plane gear 6 and the position control toothed disc 7 can effectively realize the force transmission effect, so that the position control toothed disc 7 moves. The position control toothed disc 7 is rotatably connected to the inner wall of the position control installation shell 3. The setting of the position control installation shell 3 can effectively support the position control toothed disc 7 and exert the position control effect, thereby ensuring that the position control toothed disc 7 can stably rotate in place.

[0029] As shown in Figure 3 and Figure 4As shown, the guide groove 8 is provided in the control tooth disc 7, and the linkage column 9 is slidably connected in the guide groove 8. The control tooth disc 7 can limit the linkage column 9 through the guide groove 8 and exert a power effect, so that the linkage column 9 can move.

[0030] As shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , the linkage column 9 is fixedly connected to the bottom of the pressing block 10, and the linkage column 9 and the pressing block 10 are linked. The pressing block 10 is slidably connected in the groove of the control cover plate 11, and the control cover plate 11 controls the pressing block 10 to translate in a predetermined direction, so that the linkage column 9 is stable under the action of the pressing block 10. The control cover plate 11 is fixedly connected to one side of the control installation shell 3, and one end of the pressing block 10 is inserted into the groove of the outer circumferential surface of the extrusion head 2. The arrangement between the pressing block 10 and the extrusion head 2 can preliminarily limit the extrusion head 2 to avoid falling off during reinforcement.

[0031] Working principle: when using the mechanism, the one-way motor three 16 and the heating sheet 19 are started to work synchronously. The one-way motor three 16 drives the stirring rod 18 to rotate through the linkage rod two 17, and the thermosetting plastic powder raw material stored in the stirring barrel 15 is stirred. Under the action of the heating sheet 19, the temperature in the stirring barrel 15 rises, so that the thermosetting plastic powder raw material melts. Under the action of stirring, the melting rate of the thermosetting plastic powder raw material is accelerated, and the melted thermosetting plastic powder is mixed. Then the thermosetting plastic powder enters the extrusion main body shell 1. At this time, the one-way motor two 12 is started to work, and the advancing blade 14 is driven to rotate through the linkage rod one 13. Under the influence of the blade path of the advancing blade 14 itself, the melted thermosetting plastic powder is pushed forward, so that the melted thermosetting plastic powder is discharged from the extrusion head 2. When it is necessary to replace the extrusion head 2, the one-way motor one 5 is started to work. The one-way motor one 5 drives the control tooth disc 7 to rotate in place in the control installation shell 3 through the plane gear 6. At this time, because the pressing block 10 combined with the linkage column 9 is limited by the control cover plate 11, the linkage column 9 will translate under the influence of the guide groove 8 of the control tooth disc 7, so that the linkage column 9 drives the pressing block 10 to move away from the extrusion head 2, thereby eliminating the limiting effect of the pressing block 10 on the extrusion head 2. Finally, the extrusion head 2 is pulled out from one end of the extrusion main body shell 1, realizing the effect of convenient replacement of the extrusion head 2.

[0032] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
