A rotating groove 81 is opened on the rotating plate 52. The horizontally arranged slide groove is T-shaped, and the length direction of the slide groove is consistent with the length direction of the rotating plate 52.

[0036] The vertical shaft 3 is coaxially arranged with the output shaft of the driving motor 51. The vertical shaft 3 is located at the bottom of the rotating plate 52 and is fixedly connected to the bottom of the rotating plate 52. A vertical groove 31 is opened on the side wall of the vertical shaft 3. There are two vertical grooves 31, and the two vertical grooves 31 are evenly distributed along the circumference of the vertical shaft 3. The cross-section of each vertical block 32 is T-shaped. Two vertical blocks 32 are installed on the vertical shaft 3. The two vertical blocks 32 correspond to the two vertical grooves 31 one by one. Each vertically arranged vertical block 32 is T-shaped.

[0038] The staff starts the drive motor 51, and the output shaft of the drive motor 51 rotates to drive the rotating plate 52 to rotate synchronously, thereby driving the vertical shaft 3 to rotate synchronously. Through the vertical groove 31 and the vertical block 32, the horizontal plate 41 rotates with the vertical shaft 3, thereby driving the connecting plate 43 and the stirring shaft 23 to rotate synchronously, thereby stirring the raw materials in the feed hopper 2, improving the fluidity of the raw materials in the feed hopper 2, and making it difficult for the raw materials to accumulate in the feed hopper 2 and block the feed hopper 2, thereby facilitating the transmission of the raw materials to the injection machine body 1 after passing through the feed hopper 2.

[0039] Reference Figure 3 and Figure 4 A contact piece 6 is installed in the connecting groove 44, and the contact piece 6 includes an contact rod 61 and a spring 62. The horizontally arranged contact rod 61 is located in the connecting groove 44, and one end of the contact rod 61 is fixedly connected to the side wall of the connecting groove 44, and the other end of the contact rod 61 extends into the transverse groove 42 and contacts the side wall of the transverse groove 42.

Through the elastic potential energy of the spring 62, the connecting plate 43 moves along the axial direction of the contact rod 61, thereby driving the stirring shaft 23 to move synchronously, thereby adjusting the stirring range of the stirring shaft 23, thereby adapting to feed hoppers 2 of different sizes.

[0040] Reference Figure 3 and Figure 4 A lifting member 7 and an abutment plate 82 are installed on each connecting plate 43. The lifting member 7 includes a slider 71, a cylinder 72 and a lifting rod 73. The horizontally arranged slider 71 is located in the rotating groove 81, and the side wall of the slider 71 contacts the side wall of the rotating groove 81. The cylinder 72 is located at the top of the slider 71, and the cylinder body of the cylinder 72 is fixedly connected to the top of the slider 71. The piston rod of the cylinder 72 is vertically arranged downward, and the piston rod of the cylinder 72 passes through the slider 71 and is coaxially fixedly connected to the lifting rod 73. The vertically arranged lifting rod 73 is located at the top of the connecting plate 43, and the bottom of the lifting rod 73 is fixedly connected to the top of the connecting plate 43. The inclined abutment plate 82 is located at one end of the connecting plate 43 away from the vertical axis 3, and the side wall of the abutment rod 61 contacts the inner wall of the feed trough 21. A plurality of balls 83 are installed on the side of each abutment plate 82 away from the vertical axis 3. Specifically, there are three balls 83, and the three balls 83 are evenly distributed along the length direction of the abutment plate 82. One side of each ball 83 is rotatably connected to the side wall of the abutment plate 82, and the other side of each ball 83 contacts the side wall of the feed trough 21.

[0041] The staff starts the cylinder 72, and the piston rod of the cylinder 72 rises and falls in the vertical direction. Taking the vertical downward movement of the piston rod of the cylinder 72 as an example, the downward movement of the piston rod of the cylinder 72 drives the lifting rod 73 to move synchronously, thereby driving the connecting plate 43, the abutment plate 82 and the stirring shaft 23 to move downward synchronously. At this time, the spring 62 is compressed, and the connecting plate 43 moves in the direction close to the vertical axis 3, thereby driving the stirring shaft 23, the slider 71, the cylinder 72 and the lifting rod 73 to move in the direction close to the vertical axis 3, thereby reducing the stirring range of the stirring shaft 23. When the piston rod of the cylinder 72 moves vertically upward, the lifting rod 73 moves with The piston rod of the cylinder 72 moves upward synchronously, thereby driving the connecting plate 43, the abutment plate 82 and the stirring shaft 23 to move upward synchronously. Through the elastic potential energy of the spring 62, the connecting plate 43, the stirring shaft 23 and the abutment plate 82 move in the direction close to the vertical axis 3, thereby driving the stirring shaft 23, the slider 71, the cylinder 72 and the lifting rod 73 to move in the direction away from the vertical axis 3, thereby expanding the stirring range of the stirring shaft 23, and making it convenient for the staff to adjust the stirring range of the stirring shaft 23, thereby improving the fluidity of the raw materials in the feed hopper 2, making it difficult for the raw materials to block the feed hopper 2, thereby facilitating processing by the staff.

[0042] The implementation principle of the feeding device of an injection machine in an embodiment of the present application is as follows: after the staff transfers the raw materials into the feed hopper 2, the staff starts the driving motor 51, and the output shaft of the driving motor 51 rotates to drive the rotating plate 52 to rotate synchronously with the vertical shaft 3. Through the vertical groove 31 and the vertical block 32, the horizontal plate 41 rotates with the vertical shaft 3, thereby driving the connecting plate 43, the abutment plate 82 and the stirring shaft 23 to rotate. The stirring shaft 23 stirs the raw materials in the feed hopper 2 to improve the fluidity of the raw materials, so that the raw materials are not easy to block the feed hopper 2.

[0043] At the same time, the staff starts the cylinder 72, and the lifting and lowering of the piston rod of the cylinder 72 drives the lifting rod 73 to rise and fall synchronously, thereby driving the connecting plate 43, the abutment plate 82 and the stirring shaft 23 to rise and fall synchronously. Through the elastic potential energy of the spring 62, the ball 83 on the abutment plate 82 is always in contact with the side wall of the feed trough 21, so that the connecting plate 43 and the stirring shaft 23 move in the direction close to or away from the vertical axis 3, thereby driving the stirring shaft 23 to move synchronously, thereby adjusting the stirring range of the stirring shaft 23, further improving the fluidity of the raw materials in the feed hopper 2, and making it difficult for the raw materials to block the feed hopper 2, thereby facilitating the staff to carry out subsequent processing.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
