In the barrel body 1; the rotating shaft 9 is fixedly connected to the circular plate 5; a pair of stirring rods 10 are provided on the outer side wall of one end of the rotating shaft 9 located in the barrel body 1. By putting the raw materials into the feeding shell 6, the motor 8 drives the rotating shaft 9 to rotate. Since the rotating shaft 9 is fixedly connected to the circular plate 5, the rotation of the rotating shaft 9 drives the circular plate 5 to rotate. Since the circular plate 5 is fixedly connected to the feeding shell 6, the rotation of the circular plate 5 drives the feeding shell 6 to rotate around the center of the rotating shaft 9, so that the raw materials in the feeding shell 6 will be evenly fed into the barrel body 1 as the feeding shell 6 rotates and are evenly stirred by the stirring rods 10. Since the raw materials are fed evenly, it is more convenient to stir the raw materials evenly, the stirring efficiency is higher, the required stirring time is reduced, and the energy consumption is reduced.

[0031] The bottom end of the outer wall of the rotating shaft 9 contacts the bottom end of the inner wall of the barrel body 1; a first circular groove 15 is provided at the bottom end of the outer wall of the rotating shaft 9; a reciprocating rod 16 is fixedly connected to the center of the bottom end of the inner wall of the barrel body 1, and the reciprocating rod 16 is located in the first circular groove 15; a slider 17 is provided on the outer wall of the reciprocating rod 16; a pair of square grooves 18 are provided on the outer wall of one end of the rotating shaft 9 located in the barrel body 1, and the pair of square grooves 18 are both connected to the first circular groove 15; the outer wall opposite ends of a pair of stirring rods 10 are respectively fixedly connected to the outer wall of the slider 17 on opposite sides, and the pair of stirring rods 10 pass through the pair of square grooves 18 respectively. Outside the rotating shaft 9, when the rotating shaft 9 rotates, the rotation of the rotating shaft 9 will drive the stirring rod 10 to rotate, and the rotation of the stirring rod 10 will drive the slider 17 to rotate. Because the slider 17 is arranged on the outer side wall of the reciprocating rod 16, the slider 17 will reciprocate up and down along the direction of the reciprocating rod 16 when it rotates on the reciprocating rod 16, so that the slider 17 drives the stirring rod 10 to move up and down in the square groove 18 on the rotating shaft 9, so that the stirring rod 10 can move up and down while stirring, thereby increasing the stirring range of the stirring rod 10, so that the device not only has a larger stirring range, but also has a better stirring efficiency.

[0032] A pair of first racks 19 are fixedly connected to the bottom end of the inner wall of the barrel body 1, and the first racks 19 are located in the first circular groove 15; the outer side walls of one end of a pair of stirring rods 10 located in the first circular groove 15 are fixedly connected to the second gear 20, and the pair of second gears 20 are respectively meshed with the pair of first racks 19; a pair of sealing plates 35 are slidably connected to the outer side wall of the rotating shaft 9, and the pair of sealing plates 35 are respectively rotatably connected to the pair of stirring rods 10; a pair of sealing plates 35 are respectively matched with a pair of square grooves 18; the bottom ends of the outer walls of the pair of sealing plates 35 all penetrate the barrel body 1, and the pair of sealing plates 35 are sealed and slidably connected to the barrel body 1. When the stirring rod 10 moves up and down with the up and down reciprocating motion of the slider 17, because the outer side wall of the stirring rod 10 is fixedly connected to the second gear 20, and the second gear 20 is meshed with the first rack 19, when the stirring rod 10 drives the second gear 20 to move up and down, the first rack 19 remains stationary, while the second gear 20 moves up and down, thereby making the second gear 2 When the stirring rod 10 moves up and down, it will rotate along the tooth groove of the first gear. When the first gear rotates, the first gear will drive the stirring rod 10 to rotate, so that the stirring rod 10 can not only move up and down for stirring, but also rotate while moving up and down, so that the stirring effect of the stirring rod 10 is better, so that the stirring efficiency and stirring effect of the raw materials are further improved, and through the sealing plate 35, when the stirring rod 10 moves up and down in the square groove 18, the sealing plate 35 will move up and down with it, and always keep the sealing state of the square groove 18, so that the raw material is not easy to enter the square groove 18, so that when the mechanism in the device is running, it is not easy to cause the waste of raw materials, and the outer wall bottom ends of the pair of sealing plates 35 are all through the barrel body 1, and the pair of sealing plates 35 are sealed and slidably connected with the barrel body 1, so that the sealing plate 35 can be moved out of the barrel body 1, so that the stirring lowest point of the stirring rod 10 is lower, so that the up and down moving range and stirring range of the stirring rod 10 are larger, while maintaining the sealing of the square groove 18.

[0033] A conical rack 11 is fixedly connected to the top of the inner wall of the barrel body 1; a rotating rod 12 is rotatably connected to one side of the inner wall of the feed shell 6 located in the barrel body 1, and one end of the outer wall of the rotating rod 12 passes through the feed shell 6; a first bevel gear 13 is fixedly connected to one end of the rotating rod 12 passing through the outer wall of the feed shell 6, and the first bevel gear 13 and the conical rack 11 are meshed with each other; a group of quantitative plates 14 are fixedly connected to the outer wall of one end of the rotating rod 12 located in the feed shell 6, and the quantitative plates 14 match the feed shell 6. When the feed shell 6 rotates around the center of the rotating shaft 9, the rotation of the feed shell 6 drives the rotating rod 12 to rotate. Because the rotating rod 12 is fixedly connected to one end of the outer wall of the feed shell 6, and the first bevel gear 13 and the conical rack 11 are meshed with each other, and the conical rack 11 is in a stationary state, the rotating rod 12 drives the first bevel gear 13 to rotate around When the center of the shaft 9 rotates, the first bevel gear 13 will rotate around the center of the rotating shaft 9 because the conical rack 11 is in a stationary state, so that the first bevel gear 13 drives the rotating rod 12 to rotate, and the rotation of the rotating rod 12 drives a group of quantitative plates 14 to rotate, so that when the feed shell 6 feeds, the quantitative plate 14 rotates to discharge the material quantitatively, so that the feeding operation of the device can be more uniform, and the feeding by rotating the quantitative plate 14 can effectively control the feeding efficiency, speed and quantity, so that the device can accurately control the feeding amount according to the specific situation and environment, so that the feeding amount of the raw materials can be accurately measured, which is more convenient for the staff to control the proportion of each raw material, and the automatic feeding reduces the labor intensity of the staff, and the feeding amount can be accurately controlled to avoid excessive feeding and waste.

[0034] A square shell 21 is fixedly connected to the outer wall of one end of the rotating shaft 9 located in the barrel body 1; a cleaning rod 22 is fixedly connected to one end of the inner wall of the square shell 21 through a first spring, and the cleaning rod 22 is in an inverted L shape; the outer wall of the cleaning rod 22 is slidably connected to the inner wall of the square shell 21, and one side of the outer wall of the cleaning rod 22 is in contact with the inner wall of the barrel body 1; a pair of cleaning wires 23 are fixedly connected to the opposite sides of the outer walls of the pair of sealing plates 35, and the pair of cleaning wires 23 are respectively wound around the outer walls of the pair of stirring rods 10, and the outer walls of the pair of cleaning wires 23 are respectively in contact with the outer walls of the pair of stirring rods 10. When the rotating shaft 9 rotates, the rotation of the rotating shaft 9 will drive the square shell 21 to rotate, and the rotation of the square shell 21 will drive the cleaning rod 22 to rotate, so that the cleaning rod 22 cleans the inner wall of the barrel body 1, so that the raw material is not It is easy to adhere to the inner wall of the barrel body 1, thereby further reducing the waste of raw materials and making the cleaning of the barrel body 1 more convenient. The cleaning rod 22 and the square shell 21 are connected by a first spring, so that when the cleaning rod 22 is worn, it can still fit the inner wall of the barrel body 1 for cleaning under the elastic force of the first spring, thereby increasing the service life of the cleaning rod 22. The outer walls of a pair of cleaning wires 23 are respectively in contact with the outer walls of a pair of stirring rods 10, so that when the stirring rod 10 rotates, the raw materials adhered to the stirring rod 10 will encounter the cleaning wires 23 under the rotation of the stirring rod 10, and thus be cleaned by the cleaning wires 23, so that when the stirring rod 10 is stirring, its outer surface is not easy to adhere to the raw materials, thereby further reducing the waste of raw materials and reducing the production cost of the syringe sheath.

[0035] A group of first through grooves 24 are provided on the outer wall of the stirring rod 10; an auxiliary plate 25 is slidably connected to the inner wall of the first through groove 24; a pair of first inclined surfaces 26 are provided at the corners of one end of the outer wall of the auxiliary plate 25; second inclined surfaces 27 are provided on the opposite sides of the outer wall of the first inclined surface 26, and the first inclined surface 26 and the second inclined surface 27 are matched with the cleaning wire 23, and a group of first through grooves 24 are provided through the outer wall of the stirring rod 10; the auxiliary plate 25 is slidably connected to the inner wall of the first through groove 24, so that when the stirring rod 10 is stirring, the auxiliary plate 25 can increase the stirring range of the stirring rod 10, and the stirring plate efficiency is high, so that the stirring effect of the stirring rod 10 is better, and when the auxiliary plate 25 encounters the cleaning wire through the rotation of the stirring rod 10 23, the outer side wall of the cleaning wire 23 will first encounter the second inclined surface 27 on the auxiliary plate 25. When the second inclined surface 27 encounters the cleaning wire 23, the end of the auxiliary plate 25 encountering the cleaning wire 23 will shrink, so that the cleaning wire 23 gradually contacts the first inclined surface 26 through the second inclined surface 27, thereby through the overall structure of the first inclined surface 26, the second inclined surface 27 and the auxiliary plate 25, the end encountering the cleaning wire 23 shrinks, while the end that does not encounter the cleaning wire 23 stretches, so that the auxiliary plate 25 always has a stirring effect, and when the auxiliary plate 25 shrinks, the raw materials adhered to the auxiliary plate 25 will be stirred by the outer surface of the stirring rod 10 when the auxiliary plate 25 shrinks, so that the auxiliary plate 25 is not easy to adhere to too much raw materials during stirring.

[0036] Embodiment 2:

[0037] See also Figure 8-Figure 10As shown, a vibration groove 28 is provided on one side of the inner wall of the first through groove 24; a group of third tooth grooves 29 is provided on one side of the outer wall of the auxiliary plate 25; a third round rod 30 is rotatably connected to the top end of the inner wall of the vibration groove 28; a third gear 31 is fixedly connected to the outer wall of the third round rod 30, and the third gear 31 is meshed with the third tooth groove 29; a third round groove 32 is provided at the top and bottom ends of the outer wall of the third round rod 30, and the openings of a pair of third round grooves 32 are opposite; a vibration rod 33 is fixedly connected to one end of the inner wall of the pair of third round grooves 32 through a third spring, The outer side walls of the pair of vibration rods 33 are respectively slidably connected to the inner side walls of the pair of third circular grooves 32; a vibration ball 34 is fixedly connected to one end of the outer wall of the pair of vibration rods 33, and the vibration ball 34 matches one side of the outer wall of the auxiliary plate 25 and the inner side wall of the vibration groove 28. When the auxiliary plate 25 encounters the cleaning wire 23 sliding left and right under the self-rotation stirring of the stirring plate, a group of third tooth grooves 29 are opened on one side of the outer wall of the auxiliary plate 25, and a third gear 31 is fixedly connected to the outer side wall of the third circular rod 30, and the third gear 31 and the third tooth groove 29 are meshed with each other. The left and right sliding of the auxiliary plate 25 drives the third gear 31 to rotate, and the rotation of the third gear 31 drives the third round rod 30 to rotate, and the rotation of the third round rod 30 drives a pair of vibration rods 33 and a vibration ball 34 to rotate. Because the vibration rod 33 is connected to the third through groove on the third round rod 30 through the third spring, when the vibration rod 33 and the vibration ball 34 follow the rotation of the third round rod 30, the vibration ball 34 on the vibration rod 33 will knock on one side of the outer wall of the auxiliary plate 25 and the inner wall of the vibration groove 28, so that the auxiliary plate 25 and the stirring rod 10 vibrate Because the stirring rod 10 and the auxiliary plate 25 add vibration during the stirring process, the vibration can effectively break up the agglomeration of the material, increase the contact area, and make the material particles collide violently with each other, thereby quickly mixing and improving the mixing efficiency. Through the dual effects of vibration and stirring, the material particles can fully move in the three-dimensional space, realizing the effective combination of macroscopic convection movement and microscopic diffusion movement, achieving a better homogenization effect, thereby effectively improving the mixing efficiency, improving the homogenization effect, shortening the stirring time, and improving the output efficiency.

[0038] When the present invention is in use, the raw materials are put into the feed shell 6, and the motor 8 drives the rotating shaft 9 to rotate. Since the rotating shaft 9 is fixedly connected to the circular plate 5, the rotation of the rotating shaft 9 drives the circular plate 5 to rotate. Since the circular plate 5 is fixedly connected to the feed shell 6, the rotation of the circular plate 5 drives the feed shell 6 to rotate around the center of the rotating shaft 9, so that the raw materials in the feed shell 6 are evenly fed into the barrel body 1 with the rotation of the feed shell 6 and are evenly stirred by the stirring rod 10. Since the raw materials are evenly fed, it is more convenient to evenly stir the raw materials, the stirring efficiency is higher, the required stirring time is reduced, and the energy consumption is reduced. Moreover, when the feed shell 6 rotates around the center of the rotating shaft 9, the rotation of the feed shell 6 drives the rotating rod 12 to rotate. Since the rotating rod 12 penetrates the feed shell 6, the raw materials in the feed shell 6 are evenly fed into the barrel body 1 and are evenly stirred by the stirring rod 10. A first bevel gear 13 is fixedly connected to one end of the outer wall, and the first bevel gear 13 is meshed with the conical rack 11, and the conical rack 11 is in a stationary state, so that the rotating rod 12 drives the first bevel gear 13 to rotate around the center of the rotating shaft 9. When the first bevel gear 13 rotates around the center of the rotating shaft 9, it will rotate due to the conical rack 11 being in a stationary state, so that the first bevel gear 13 drives the rotating rod 12 to rotate, and the rotation of the rotating rod 12 drives a group of quantitative plates 14 to rotate, so that when the feed shell 6 feeds, the quantitative plate 14 rotates to discharge the material quantitatively, so that the device can feed more evenly when feeding, and the feeding efficiency, speed and quantity of the feeding can be effectively controlled by feeding through the rotation of the quantitative plate 14, so that the device can be used according to The feeding amount can be accurately controlled according to the specific situation and environment, so that the feeding amount of the raw materials can be accurately measured, which is more convenient for the staff to control the proportion of each raw material, and the automatic feeding reduces the labor intensity of the staff, and the accurate control of the feeding amount can avoid excessive feeding and waste. When the rotating shaft 9 rotates, the rotation of the rotating shaft 9 will drive the stirring rod 10 to rotate, and the rotation of the stirring rod 10 will drive the slider 17 to rotate. Because the slider 17 is arranged on the outer wall of the reciprocating rotating rod 16, the slider 17 will reciprocate up and down along the direction of the reciprocating rotating rod 16 when it rotates on the reciprocating rotating rod 16, so that the slider 17 drives the stirring rod 10 to move up and down in the square groove 18 on the rotating shaft 9, so that the stirring rod 10 can move up and down while stirring, thereby increasing the stirring efficiency. The stirring range of the stirring rod 10 is increased, so that the stirring range of the device is not only larger, but also the stirring efficiency is better. When the stirring rod 10 moves up and down with the up and down reciprocating motion of the slider 17, because the outer wall of the stirring rod 10 is fixedly connected with the second gear 20, and the second gear 20 and the first rack 19 are meshed with each other, when the stirring rod 10 drives the second gear 20 to move up and down, the first rack 19 remains stationary, and the second gear 20 moves up and down, so that the second gear 20 rotates along the tooth groove of the first gear when moving up and down, and when the first gear rotates, the first gear drives the stirring rod 10 to rotate, so that the stirring rod 10 can not only move up and down for stirring, but also rotate while moving up and down, so that the stirring effect of the stirring rod 10 is better.Thereby, the stirring efficiency and stirring effect of the raw materials are further improved, and through the sealing plate 35, when the stirring rod 10 moves up and down in the square groove 18, the sealing plate 35 will move up and down with it, and always keep the sealing state of the square groove 18, so that the raw materials are not easy to enter the square groove 18, so that when the mechanism in the device is in operation, it is not easy to cause waste of raw materials, and the outer wall bottom ends of a pair of sealing plates 35 pass through the barrel body 1, and the pair of sealing plates 35 are sealed and slidably connected with the barrel body 1, so that the sealing plate 35 can be moved out of the barrel body 1, so that the stirring lowest point of the stirring rod 10 is lower, the up and down moving range and the stirring range of the stirring rod 10 are larger, and the sealing of the square groove 18 is maintained, and when the rotating shaft 9 rotates, the rotation of the rotating shaft 9 will The square shell 21 is driven to rotate, and the rotation of the square shell 21 will drive the cleaning rod 22 to rotate, so that the cleaning rod 22 cleans the inner wall of the barrel body 1, so that the raw materials are not easy to adhere to the inner wall of the barrel body 1, thereby further reducing the waste of raw materials and making the cleaning of the barrel body 1 more convenient. The cleaning rod 22 and the square shell 21 are connected by a first spring, so that when the cleaning rod 22 is worn, it can still fit the inner wall of the barrel body 1 for cleaning under the elastic force of the first spring, thereby increasing the service life of the cleaning rod 22. The outer walls of the pair of cleaning wires 23 are respectively in contact with the outer walls of the pair of stirring rods 10, so that when the stirring rod 10 rotates, the raw materials adhered to the stirring rod 10 will encounter the cleaning rod 22 under the rotation of the stirring rod 10. The stirring rod 10 is provided with a plurality of first through grooves 24 on its outer wall, and an auxiliary plate 25 is slidably connected to the inner wall of the first through groove 24, so that when the stirring rod 10 is stirring, the auxiliary plate 25 can increase the stirring range of the stirring rod 10, and the stirring plate efficiency is high, so that the stirring rod 10 has a better stirring effect, and when the auxiliary plate 25 encounters the cleaning wire 23 through the rotation of the stirring rod 10, the outer wall of the cleaning wire 23 will first encounter the second inclined surface 27 on the auxiliary plate 25, and when the second inclined surface 27 encounters the cleaning wire 23, the auxiliary plate 25 encounters the cleaning wire 23. The end of the auxiliary plate 25 will shrink, so that the cleaning wire 23 gradually contacts the first inclined surface 26 through the second inclined surface 27, so that the end that encounters the cleaning wire 23 shrinks through the first inclined surface 26, the second inclined surface 27 and the overall structure of the auxiliary plate 25, while the end that does not encounter the cleaning wire 23 stretches, so that the auxiliary plate 25 always has a stirring effect, and when the auxiliary plate 25 encounters the cleaning wire 23 and slides left and right under the self-rotation stirring of the stirring plate, because a group of third tooth grooves 29 are opened on one side of the outer wall of the auxiliary plate 25, and the outer side wall of the third round rod 30 is fixedly connected with the third gear 31, and the third gear 31 is meshed with the third tooth groove 29, the left and right sliding of the auxiliary plate 25 drives the third gear 31 to rotate, and the rotation of the third gear 31 drives the third round rod 30 to rotate.The rotation of the third round rod 30 drives a pair of vibration rods 33 and vibration balls 34 to rotate. Since the vibration rod 33 is connected to the third through slot on the third round rod 30 through the third spring, when the vibration rod 33 and the vibration ball 34 follow the rotation of the third round rod 30, the vibration ball 34 on the vibration rod 33 will knock on one side of the outer wall of the auxiliary plate 25 and the inner wall of the vibration slot 28, thereby causing the auxiliary plate 25 and the stirring rod 10 to vibrate. Since the stirring rod 10 and the auxiliary plate 25 add vibration during the stirring process, the vibration can effectively break the agglomeration state of the material, increase the contact area, and make the material particles collide violently with each other, thereby quickly mixing and improving the mixing efficiency. Through the dual effects of vibration and stirring, the material particles are fully moved in three-dimensional space, realizing the effective combination of macroscopic convection movement and microscopic diffusion movement, and achieving a better homogenization effect, thereby effectively improving the mixing efficiency, improving the homogenization effect, shortening the stirring time, and improving the output efficiency.
