[0026] Referring to Figure 4 , in the embodiment: the bottom of scraper 16 is equipped with slope 19, by moving circular ring 5 downward and contacting with the top of storage barrel 18, by equipping slope 19 in the bottom of scraper 16, the bottom of scraper 16 can be shrunk to the inside of hollow plate 14 by the shape of bottom when contacting the top of storage barrel 18, so that staff is more convenient when using.

[0027] Referring to Figure 3 and Figure 5As shown, in the embodiment: the two ends of the inner cavity of the hollow plate 14 are provided with limiting grooves 20, and the two ends of the scraper 16 are fixedly connected with limiting blocks 21. The surface of the limiting block 21 is in sliding connection with the inside of the limiting groove 20. By providing the limiting block 21 at the two ends of the hollow plate 14, the mutual cooperation of the limiting block 21 and the limiting groove 20 can make the movement trajectory of the scraper 16 more stable, and the shaking situation can be avoided.

[0028] Referring to Figure 6 As shown, in the embodiment: the two ends of the inner cavity of the movable groove 3 are provided with sliding grooves 22, and the two ends of the connecting block 4 are fixedly connected with sliding blocks 23. The surface of the sliding block 23 is in sliding connection with the inside of the sliding groove 22. By the cooperation of the sliding block 23 and the sliding block 23, the guiding effect can be achieved, and the connecting block 4 can smoothly slide in the inner cavity of the movable groove 3. When the connecting block 4 is pulled by an external force, the sliding block 23 will move along the trajectory of the sliding groove 22, ensuring that the movement path of the connecting block 4 is fixed and stable.

[0029] Referring to Figure 1 , Figure 6 and Figure 7 As shown, in the embodiment: one end of the connecting block 4 is fixedly connected with a hollow block 24, the inside of the hollow block 24 is in sliding connection with a moving rod 25, one end of the moving rod 25 is fixedly connected with a pulling plate 26, one end of the pulling plate 26 is fixedly connected with a clamping block 27, the bottom of one end of the fixed block 2 is provided with a first clamping groove 28, and the bottom of one side of the fixed block 2 is provided with a second clamping groove 29. When the raw materials are stirred, and the bottom of the circular ring 5 is attached to the top of the storage barrel 18, the position of the pulling plate 26 is moved, the moving rod 25 is moved to the inside of the hollow block 24, and then the clamping block 27 at one end of the pulling plate 26 is inserted into the second clamping groove 29, so as to fix the stirring device. When the raw materials are stirred, the staff can be more stable, and shaking can be avoided.

[0030] Referring to Figure 7 As shown, in the embodiment: one end of the moving rod 25 is fixedly connected with a return spring 30, and one end of the return spring 30 is fixedly connected with the inside of the hollow block 24. When the staff moves the pulling plate 26 outward, the return spring 30 at one end of the moving rod 25 will start to store power. When the staff releases the pulling plate 26, the return spring 30 will drive the moving rod 25 and the pulling plate 26 to quickly rebound by its own force, so that the staff can be fixed more quickly.

[0031] Referring to Figure 1 and Figure 7As shown, in the embodiment: the external shape of the clamping block 27 is consistent with the internal shape of the first clamping groove 28 and the second clamping groove 29, and because the shapes of the clamping block 27, the first clamping groove 28 and the second clamping groove 29 are mutually consistent, the cooperation between them can be more accurate, and the instability caused by gaps or misalignment can be reduced. This accurate cooperation helps to improve the stability and reliability of the fixing structure.

[0032] With reference to Figure 6 As shown, in the embodiment: the top of the connecting block 4 is fixedly connected with a tension spring 31, and the top of the tension spring 31 is fixedly connected with the top of the inner cavity of the movable groove 3. Through the tension spring 31, when the worker does not use the stirring device, the tension spring 31 can drive the connecting block 4 and the circular ring 5 to quickly rebound upward, so as to facilitate the worker to take out the storage barrel 18.

[0033] Working principle: After the staff puts the storage barrel 18 in the circular groove 17 on the top of the bottom plate 1, the bottom of the circular ring 5 is in abutment with the top of the storage barrel 18 by moving the connecting block 4 downward to drive the circular ring 5, then the motor 7 is started to drive the first gear 8 to rotate, and then the first connecting rod 11 at the bottom and the stirring blade 12 are rotated to stir the raw materials in the barrel, at the same time, when the first gear 8 rotates, the second gear 9 meshing connected on one side will make a circular motion around the gear block 10, and cooperate with the hollow plate 14 to make the scraper 16 inside more closely attached to the inner wall of the storage barrel 18 under the action of the push spring 15, so as to avoid the raw materials from adhering to the barrel wall during stirring, and to avoid the uneven material caused by the agglomeration of raw materials, thereby affecting the quality of the final injection molding product. When the circular ring 5 is moved downward and in contact with the top of the storage barrel 18, the slope 19 is opened at the bottom of the scraper 16, which can make the bottom of the scraper 16 shrink into the hollow plate 14 when it contacts the top of the storage barrel 18, so that the staff can use it more conveniently. By setting the limiting block 21 at both ends of the hollow plate 14, the limiting block 21 and the limiting groove 20 can cooperate with each other when the scraper 16 moves inside the hollow plate 14, so that the movement track of the scraper 16 is more stable and will not shake. Through the cooperation of the sliding block 23 and the sliding block 23, the guiding effect can be achieved, so that the connecting block 4 can smoothly slide in the inner cavity of the movable groove 3. When the connecting block 4 is pulled by external force, the sliding block 23 will move along the track of the sliding groove 22, ensuring that the movement path of the connecting block 4 is fixed and stable. When the raw materials are stirred and the bottom of the circular ring 5 is in close contact with the top of the storage barrel 18, the position of the pulling plate 26 is moved, the pulling rod 25 is moved into the hollow block 24, and then the clamping block 27 at one end of the pulling plate 26 is inserted into the second clamping groove 29, so that the stirring device is fixed, and the staff can stir the raw materials more stably and will not shake. When the staff moves the pulling plate 26 outward, the reset spring 30 at one end of the moving rod 25 will begin to store energy. When the staff releases the pulling plate 26, the reset spring 30 will drive the moving rod 25 and the pulling plate 26 to rebound quickly, so that the staff can fix it more quickly. Since the shape of the clamping block 27 is consistent with that of the first clamping groove 28 and the second clamping groove 29, the cooperation between them can be more accurate, reducing the instability caused by gaps or misalignment. This precise cooperation helps to improve the stability and reliability of the fixing structure. By setting the tension spring 31, the staff can quickly rebound the connecting block 4 and the circular ring 5 upward when not using the stirring device, which is convenient for the staff to take out the storage barrel 18.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
