[0041] See also Figure 3 and Fig. 9As shown, a square shell 34 is fixedly connected to one side of the outer wall of the feed shell 3, and the square shell 34 is inclined, and the square shell 34 is connected to the feed shell 3; a control plate 35 is provided on the inner wall of the square shell 34; a cleaning plate 36 is fixedly connected to one side of the outer wall of the control plate 35 through a group of springs, and the outer side wall of the cleaning plate 36 is slidably connected to the inner side wall of the square shell 34; the cleaning plate 36 matches the quantitative plate 7, and when the quantitative plate 7 rotates, the quantitative plate 7 rotates to discharge the material as the quantitative plate 7 rotates, and the material is easy to adhere to the outer side wall of the quantitative plate 7, so that the material discharge is easy to be uneven, and the material is also easy to adhere to the outer side wall of the quantitative plate 7, which causes the material on the quantitative plate 7 to solidify and accumulate, thereby blocking the quantitative plate 7, so that When the quantitative plate 7 fails, a cleaning plate 36 is fixedly connected to one side of the outer wall of the control plate 35 through a group of springs, and the cleaning plate 36 matches the quantitative plate 7, so that the quantitative plate 7 rotates to the bottom to complete the unloading operation, and then continues to rotate. At this time, the quantitative plate 7 will contact the cleaning plate 36. At this time, the quantitative plate 7 continues to rotate. At this time, the cleaning plate 36 will drive the spring to contract as the quantitative plate 7 rotates, so that the cleaning plate 36 will scrape the outer wall of the quantitative plate 7 to scrape off the material adhered to the outer wall of the quantitative plate 7, thereby reducing the probability of material adhering to the quantitative plate 7, so that the uniformity and stability of the operation of the device are guaranteed, and the material is not easily wasted, and the quantitative plate 7 is not prone to failure due to material adhesion.

[0042] The outer wall of the control plate 35 is slidably connected to the inner wall of the square shell 34; one end of the outer wall of the control plate 35 is rotatably connected with a threaded rod 37, and one end of the outer wall of the threaded rod 37 passes through the square shell 34; the threaded rod 37 is threadedly connected to the square shell 34; the cleaning plate 36 is sealed and slidably connected to the connecting part of the square shell 34 and the feeding shell 3, and by rotating the threaded rod 37, because the threaded rod 37 is threadedly connected to the square shell 34, the rotation of the threaded rod 37 causes the threaded rod 37 to move up and down in the square shell 34, so that the threaded rod 37 drives the control plate 35 to move up and down in the square shell 34, so that the control plate 35 drives the spring and the cleaning plate 36 to move, so that the movement of the control plate 35 can control the squeezing force of the spring on the cleaning plate 36, so that the device can adjust the elastic force of the spring on the cleaning plate 36 according to the viscosity of the material or other conditions, so that the cleaning plate 36 can better scrape the material while reducing the wear of the cleaning plate 36 on the quantitative plate 7.

[0043] When the present invention is in use, by placing the material into the placement shell 4, the object will enter the feed shell 3 through the placement shell 4, at this time, the motor 5 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives a group of quantitative plates 7 to rotate, the rotation of the quantitative plates 7 drives the material in the feed shell 3, so that the material falls into the screw extruder body 2 and is extruded under the rotation of the quantitative plates 7, when the material in the screw extruder body 2 is more, the rotation of the motor 5 is stopped, and the feeding of the material is stopped at this time, when the material is needed in the screw extruder body 2, the motor 5 drives the rotating shaft 6 and the quantitative plates 7 to rotate, and the material is unloaded, so that the present device can control the feeding of the material, thereby avoiding the problem that the screw extruder body 2 fails due to the large amount of internal material, thereby being more intelligent, convenient and practical.

[0044] Uneven feeding will cause the screw extruder body 2 to fluctuate during operation, affecting the quality and stability of the product. The device can make the feeding more uniform through quantitative feeding, so that the quality and stability of the product are higher. When the quantitative plate 7 rotates, the quantitative plate 7 rotates to feed the material as the quantitative plate 7 rotates. The material is easy to adhere to the outer wall of the quantitative plate 7, which makes the feeding of the material uneven. The material also adheres to the outer wall of the quantitative plate 7, which easily leads to the solidification and accumulation of the material on the quantitative plate 7, thereby blocking the quantitative plate 7 and causing the quantitative plate 7 to malfunction. A cleaning plate 36 is fixedly connected to one side of the outer wall of the control plate 35 through a group of springs, and the cleaning plate 36 is matched with the quantitative plate 7. After the quantitative plate 7 rotates to the bottom to complete the feeding operation, it continues to rotate. At this time, the quantitative plate 7 will contact the cleaning plate 36. At this time, the quantitative plate 7 continues to rotate. At this time, the cleaning plate 36 will drive the spring to contract as the quantitative plate 7 rotates. , so that the cleaning plate 36 will scrape the outer wall of the quantitative plate 7 and scrape off the material adhered to the outer wall of the quantitative plate 7, thereby reducing the probability of material adhering to the quantitative plate 7, thereby ensuring the uniformity and stability of the operation of the device, and preventing material from being wasted, and preventing the quantitative plate 7 from malfunctioning due to material adhesion. By rotating the threaded rod 37, because the threaded rod 37 is threadedly connected to the square shell 34, the rotation of the threaded rod 37 causes the threaded rod 37 to move up and down in the square shell 34, so that the threaded rod 37 drives the control plate 35 to move up and down in the square shell 34, so that the control plate 35 drives the spring and the cleaning plate 36 to move, so that the movement of the control plate 35 can control the extrusion force of the spring on the cleaning plate 36, so that the device can adjust the elastic force of the spring on the cleaning plate 36 according to the viscosity of the material or other conditions, so that the cleaning plate 36 can better scrape off the material while reducing the wear of the cleaning plate 36 on the quantitative plate 7.

[0045] When the rotating shaft 6 rotates, since the rotating rod 8 passes through one end of the outer wall of the placement shell 4 and the outer side wall of the rotating shaft 6 are fixedly connected with the first sprocket 9, and the pair of first sprockets 9 are connected by the first chain 10, the rotation of the rotating shaft 6 drives the rotating rod 8 to rotate through the first sprocket 9 and the first chain 10, and the rotation of the rotating rod 8 drives the pair of stirring plates 12 to rotate through the pair of connecting rods 11, so that the stirring plates 12 stir the materials in the placement shell 4, so that the materials are mixed more evenly, and the rotation of the stirring plates 12 can drive the materials to rotate, thereby solving the problem of static accumulation and solidification of materials.

[0046] When the rotating rod 8, the connecting rod 11 and the stirring plate 12 rotate, because a pair of connecting rods 11 are fixedly connected to one end of the outer wall in the circular groove 13 with a second bevel gear 15, and a pair of second bevel gears 15 are meshed with the first bevel gear 14, and the first bevel gear 14 is in a fixed and stationary state, the connecting rod 11 drives the second bevel gear 15 to rotate around the center of the rotating rod 8. At this time, the second bevel gear 15 rotates, and the first bevel gear 14 is stationary, so that the second bevel gear 15 rotates while rotating, so that the second bevel gear 15 drives the connecting rod 11 and the stirring plate 12 to rotate, so that the stirring plate 12 can rotate while rotating, so that its stirring effect and stirring efficiency are further improved, so that the effect of material stirring is better.

[0047] When the stirring plate 12 rotates, the rotation of the stirring plate 12 drives a pair of first rotating rods 19, the third gear 20 and the two groups of rotating plates 21 to rotate around the center of the stirring plate 12. Because the pair of third gears 20 are meshed with the first annular rack 17, and the first annular rack 17 is stationary, when the pair of third gears 20 rotate, the stationary first annular rack 17 rotates, so that the rotation of the pair of third gears 20 drives the pair of first rotating rods 19 and the two groups of rotating plates 21 to rotate, and the two groups of rotating plates 21 rotate in the square through groove 18 in the stirring plate 12. Therefore, when the stirring plate 12 is stirring, the rotation of the two groups of rotating plates 21 assists the stirring plate 12 to stir, so that the stirring effect of the device is better, so that the materials can be mixed more quickly and efficiently, and the probability of the materials being stationary and solidified is reduced.

[0048] Because the third gear 20 is located in the sealing plate 22 and the circular shell 16, and the circular shell 16 and the sealing plate 22 form a sealed space, the material will not enter the circular shell, so that the rotation of the rotating plate 21 will not be affected, so that the safety and stability of the device during operation are relatively high, and when the stirring plate 12 rotates, it will also drive the pair of second rotating rods 24, the fifth gear 25 and the two sets of auxiliary plates 26 to rotate. Because the pair of fifth gears 25 are meshed with the second annular rack 23, when the pair of fifth gears 25 rotate, the static second annular rack 23 will rotate, so that the fifth gears 25 The wheel 25 drives the second rotating rod 24 to rotate, so that the second rotating rod 24 drives the auxiliary plate 26 to rotate, so that the two groups of auxiliary plates 26 cooperate with the two groups of rotating plates 21 to stir, so that when the stirring plate 12 is stirring, the auxiliary plate 26 and the rotating plate 21 cooperate with each other to stir the materials, so that the materials collide with each other under multiple rotational forces or are broken up and stirred by the auxiliary plate 26 and the rotating plate 21, so that the materials can be stirred and mixed under the cooperation of the stirring plate 12, the rotating plate 21 and the auxiliary plate 26, so that large materials are broken up under stirring and become smaller, so that they are easier to mix.

[0049] Under the multiple stirring forces, the materials are also easier to mix, so that the mixing efficiency and mixing effect of the materials in the placement shell 4 are further improved, and when the rotating shaft 6 rotates, the rotation of the rotating shaft 6 drives the sixth bevel gear 29 to rotate. Because the seventh bevel gear 31 is fixedly connected to one end of the outer wall of the fifth rotating rod 30, and the seventh bevel gear 31 and the sixth bevel gear 29 are meshed with each other, the rotation of the sixth bevel gear 29 drives the fifth rotating rod 30 to rotate through the seventh bevel gear 31. Because the other end of the outer wall of the fifth rotating rod 30 and the circular rod 27 penetrate the outer wall of the placement shell 4, the rotation of the sixth bevel gear 29 drives the fifth rotating rod 30 to rotate. A second sprocket 32 ​​is fixedly connected to one end of the wall, and a pair of second sprockets 32 are connected by a second chain 33, so that the rotation of the fifth rotating rod 30 drives the circular rod 27 to rotate through the second sprocket 32 ​​and the second chain 33, and the circular rod 27 drives a group of square plates 28 to rotate. Because the square plate 28 is located between the stirring plate 12 and the quantitative plate 7, the stirring plate 12 cooperates with the square plate 28 to stir the material, so that the material is turned upside down, thereby avoiding material accumulation and sedimentation, thereby improving the quality of the material and improving the quality of the extruded product.

[0050] When the circular rod 27 rotates, the rotation of the circular rod 27 drives the reciprocating rod 38 to rotate through a pair of eighth gears 39, so that the reciprocating rod 38 drives the slider 40, the eighth rotating rod 41 and the anti-coagulation plate 42 to move back and forth, so that the movement of the anti-coagulation plate 42 drives the material to move, thereby coordinating the stirring plate 12 and the square plate 28. When the slider 40 drives the eighth rotating rod 41 to rotate, the rotation of the eighth rotating rod 41 drives the ninth gear 47 to move. Because the ninth rack 48 and the ninth gear 47 are meshed with each other, the ninth rack 48 and the ninth gear 47 are meshed with each other. When the ninth gear 47 moves, the ninth rack 48 in a fixed stationary state will rotate, so that the ninth gear 47 drives the eighth rotating rod 41 and the anti-solidification plate 42 to rotate, so that the anti-solidification plate 42 moves and rotates at the same time, so that the anti-solidification effect of the anti-solidification plate 42 is further improved, and the protective shell 44 and the protective shell 43 can prevent the material from entering and contacting the eighth gear 39, the ninth gear 47, and the ninth rack 48, thereby ensuring the stable operation of the eighth gear 39, the ninth gear 47, and the ninth rack 48.
