[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0024] Example 1: The present invention provides a raw material mixing device for producing heat shrinkable film, such as Figures 1 to 7 As shown, it includes a mixing barrel 1, a barrel cover 2 is clamped on the top of the mixing barrel 1, a discharge pipe 10 is fixedly connected to the bottom end of the mixing barrel 1 at the midpoint, a motor 3 is fixedly connected to the top end of the barrel cover 2 at the midpoint, a linkage rod 4 is fixedly connected to the output shaft of the motor 3, the linkage rod 4 is rotatably connected to the inside of the barrel cover 2, and a blade 5 is fixedly connected to the outer surface of the linkage rod 4 at a position below the barrel cover 2;

[0025] A slide groove 6 is provided inside the linkage rod 4 at a position below the blade 5, and a slider 7 is slidably connected inside the slide groove 6. The bottom end of the slider 7 is fixedly connected to a spring telescopic rod 8, and the bottom end of the spring telescopic rod 8 is fixedly connected to the inside of the linkage rod 4. One end of the slider 7 is fixedly connected to a discharge tray 15, and the inside of the discharge tray 15 is movably connected to the outer surface of the linkage rod 4. The bottom end of the discharge tray 15 is fixedly connected to a sleeve 9, and the inside of the sleeve 9 is movably connected to the outer surface of the linkage rod 4. The outer surface of the linkage rod 4 is fixedly connected to a stirring blade 11 at a position below the discharge tray 15.

[0026] like Figure 1 and Figure 2 As shown, the top of the barrel cover 2 is located outside the motor 3 and is fixedly connected to a feed pipe 12, the bottom end of the feed pipe 12 is fixedly connected to a discharge cover 13, and the bottom end of the discharge cover 13 is fixedly connected to a discharge plate 14. A number of discharge holes are equidistantly provided inside the discharge plate 14. The material to be mixed is poured into the feed pipe 12, and the material can fall at a uniform speed along the discharge cover 13 and the discharge plate 14, which effectively avoids local concentrated discharge of the material and improves the mixing uniformity of the material.

[0027] like Figure 1 and Figure 3 As shown, the outer surface of the discharge tray 15 is movably connected to the inside of the mixing barrel 1, and a plurality of discharge holes are opened inside the discharge tray 15, so that the material can be evenly transported to the bottom of the mixing barrel 1 through the discharge holes, thereby improving the mixing uniformity of the material.

[0028] like Figure 1 and Figure 6 As shown, the shape of the slider 7 is T-shaped, and the width of one end of the slider 7 close to the discharge tray 15 is smaller than the width of the other end, which can provide stable support, prevent the discharge tray 15 from shaking left and right, and improve the stability of the discharge tray 15.

[0029] like Figure 1 and Figure 3As shown, the center of the sleeve 9 is on the same vertical line as the center of the linkage rod 4, and the diameter of the sleeve 9 is larger than the diameter of the linkage rod 4. The sleeve 9 can effectively prevent materials from entering the chute 6, affecting the sliding of the slider 7 and ensuring that the slider 7 can be used normally.

[0030] like Figure 1 and Figure 2 As shown, the bottom end of the material cover 13 is at a level higher than the blade 5 , which prevents the blade 5 from colliding with the material cover 13 during rotation, thereby ensuring stable operation of the equipment.

[0031] Working principle: During actual use of the device, the motor 3 is first started. The rotation of the motor 3 drives the linkage rod 4 to rotate synchronously. The rotation of the linkage rod 4 can drive the discharge plate 15 and the stirring blade 11 to rotate synchronously. Then, the material to be mixed is poured into the feed pipe 12. The material will enter the discharge cover 13 along the feed pipe 12 and fall on the top surface of the discharge plate 14. Then, the material will be discharged at a uniform speed along the discharge plate 14 and enter the mixing barrel 1. This can avoid the situation of localized concentrated discharge of materials, make the materials fall evenly, and effectively improve the uniformity of material mixing.

[0032] Then, after the material enters the mixing barrel 1, it will fall on the top surface of the discharge tray 15. Due to the increase in gravity, the slider 7 will squeeze the spring telescopic rod 8, causing the spring telescopic rod 8 to contract, thereby lowering the discharge tray 15. As the material is discharged along the discharge hole, the gravity of the discharge tray 15 will change. The change in gravity of the discharge tray 15 will cause the spring telescopic rod 8 to rebound, causing the discharge tray 15 to move upward. Since the gravity of the discharge tray 15 cannot be kept constant, the discharge tray 15 will shake up and down. The shaking of the discharge tray 15 up and down can make the material discharge process smoother, reduce the risk of accumulation and blockage, and increase the material discharge rate.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
