DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Embodiment 1: Figure 1 , Figure 2 As shown, the chemical homogenizing batching equipment comprises a plurality of injection barrels 2, which are neatly arranged in a packaging box 1, a plug plate 21 is adapted to be slidably installed in each injection barrel 2, a three-way valve tube 4 is installed at the output outer end of each injection barrel 2, the three-way valve tube 4 has three ports, wherein the first port passes through the injection barrel 2, the second port is provided with a one-way valve for one-way conduction to the injection barrel 2, and the second port is connected to an external raw material storage unit through a liquid inlet pipe 5, and the third port is provided with a one-way valve for one-way conduction to the outside of the injection barrel 2, a mixing component 7 is arranged below the packaging box 1, the third port of the three-way valve tube 4 is connected to the mixing component 7 through a liquid discharge pipe 6, a shaft 8 is rotatably installed in the packaging box 1, the shaft 8 is parallel to the arrangement direction of the injection barrel 2, a plurality of eccentric components are provided on the surface of the shaft 8, and the eccentric components are aligned one by one with the inner ends of each injection barrel 2, a motor 3 is installed on the outside of the packaging box 1, and an output shaft of the motor 3 is connected to one end of the shaft 8 through a belt drive; like Figure 3 , Figure 4 As shown, the eccentric assembly includes two slides 81 perpendicular to the shaft 8, one end of the two slides 81 is connected to a shaft handle 84 parallel to the shaft 8, the slides 81 and the shaft handle 84 are U-shaped, the shaft 8 is fixedly connected to two C-shaped slides 83, the slides 81 and the slides 83 keep linear sliding, which is used to adjust the offset distance between the shaft handle 84 and the shaft 8, and multiple screws are threaded through the surface of the slide 83 to squeeze and position the slide 81, one end of the swing rod 82 is connected to the shaft handle 84, and the other end is inserted into the injection barrel 2 and rotatably connected to the plug plate 21; The three-fork valve tube 4 at the end of each injection barrel 2 is connected to a raw material storage unit through a liquid inlet pipe 5. The inner diameter of the injection barrel 2 is fixed. The single material guide amount is controlled by adjusting the stroke of the single plug plate 21 in the injection barrel 2. The guide amount of each raw material each time is determined according to the proportion. The slide 81 is slid along the slide seat 83 by loosening the screws, and the eccentric distance between the shaft handle 84 and the shaft member 8 is adjusted to accurately control the proportion of each material. The motor 3 is turned on to drive the shaft member 8 and all eccentric components to rotate. The eccentric shaft handle 84 is used to push and pull the rocker rod 82 back and forth to make the plug plate 21 perform piston motion in the injection barrel 2. When the plug plate 21 is pulled outward, the raw material of the raw material storage unit is introduced into the injection barrel 2 through the liquid inlet pipe 5. When the plug plate 21 is compressed inward, the raw material is introduced into the mixing component 7 through the discharge pipe 6 for mixing, thereby forming intermittent fixed ratio feeding.

[0027] If the required raw material types are small, there will be an empty injection barrel 2. At this time, you only need to slide the slide 81 to align the shaft handle 84 concentrically with the shaft 8. During the rotation of the shaft 8, the plug plate 21 will not be moved, so that the empty injection barrel 2 will not perform the material guiding work.

[0028] Each group of injection barrels 2 is symmetrically arranged with two, and the plug plates 21 in the two injection barrels 2 are connected to the same eccentric component. The two symmetrically distributed injection barrels 2 are connected to the same raw material storage unit. The shaft 8 completes two fixed-ratio feedings every time it rotates one circle, which improves the efficiency of proportional feeding and makes the rotation of the shaft 8 more stable.

[0029] like Fig.10 As shown, the mixing assembly 7 includes a material pipe 71, a single end of which is through-connected and used to transfer the proportioned raw materials to the processing step. A core shaft 72 is rotatably installed in the material pipe 71, and a plurality of groups of stirring plates 73 are obliquely arranged around the surface of the core shaft 72. Each group of stirring plates 73 has two stirring plates, and the stirring plates 73 of adjacent groups are staggered in angle. The output shaft of the motor 3 is connected to the core shaft 72 through a belt drive, and all the discharge pipes 6 are connected to the material pipe 71. During the batching process, the raw materials are introduced into the material pipe 71 through the discharge pipe 6, and the core shaft 72 is driven to rotate by the motor 3, so that the inclined stirring plate 73 pushes the materials toward the end of the material pipe 71 during the mixing and stirring process of the raw materials, thereby achieving rapid mixing and discharging; like Fig.11 As shown, each stirring plate 73 is elastically rotatably connected to the core shaft 72 through a torsion spring, and a spherical stopper 74 is provided on the inner wall of the material tube 71. The stirring plate 73 is blocked by the spherical stopper 74 during the rotating mixing process and can be deflected at an angle, so that the angle of the stirring plate 73 changes dynamically, which is used to change the stirring direction and stirring speed of the material and increase the mixing effect.

[0030] Embodiment 2: Figure 5 , Figure 6 , Fig. 9 As shown, the eccentric assembly includes a disc 85, and a radial groove 89 is provided on the surface of the disc 85 extending from the center to the edge, and the width of the radial groove 89 is uniform. The surface of the shaft 8 has a square body 810, and the square body 810 passes through the radial groove 89 and is slidably connected with the radial groove 89, so that the disc 85 can be slidably adjusted with respect to the eccentricity of the shaft 8, and the two ends of the square body 810 have an enlarged diameter threaded portion 811, and the enlarged diameter threaded portion 811 is used to resist and limit the axial position of the disc 85 on the surface of the shaft 8, and the enlarged diameter threaded portion 811 is threadedly connected with a nut, and is used to squeeze and position the disc 85 relative to the shaft 8 by locking the nut, and the side edge of the disc 85 has an annular groove 88, and the surface of the plug plate 21 is fixed with a push handle 86, and the end side of the push handle 86 has a rotating column 87, and the rotating column 87 is adapted to be inserted into the slide groove; The eccentric distance between the sliding disc 85 and the shaft 8 is adjusted by loosening the nut, so as to adjust the movement stroke of the plug plate 21, thereby controlling the single material feeding amount. The disc 85 is driven to rotate by the shaft 8, and the rotating column 87 is limited by the annular groove 88, so that the push handle 86 reciprocates to push and pull the plug plate 21 in the injection barrel 2 to make a piston motion, thereby realizing intermittent fixed ratio feeding; For an empty injection barrel 2, it is only necessary to slide and adjust the disc 85 to align with the center of the shaft 8. The eccentric distance between the disc 85 and the shaft 8 is zero, and the plug plate 21 remains in a fixed position without performing material guiding work.

[0031] Embodiment 3: Figure 7 , Figure 8 , Fig. 9 As shown, the eccentric assembly includes a disc 85, and a radial groove 89 is provided on the surface of the disc 85 extending from the center to the edge, and the width of the radial groove 89 is uniform. The surface of the shaft 8 has a square body 810, and the square body 810 passes through the radial groove 89 and is slidably connected with the radial groove 89, so that the disc 85 can be slidably adjusted with respect to the eccentricity of the shaft 8, and the two ends of the square body 810 have an enlarged diameter threaded portion 811, and the enlarged diameter threaded portion 811 is used to contact and limit the axial position of the disc 85 on the surface of the shaft 8, and the enlarged diameter threaded portion 811 is threadedly connected with a nut, and is used to squeeze and position the disc 85 relative to the shaft 8 by locking the nut, and a push handle 86 is fixed on the surface of the plug plate 21, and the end of the push handle 86 is a smooth arc surface, and the smooth arc end of the push handle 86 contacts the edge of the disc 85, and the plug plate 21 is connected to the injection barrel 2 through a spring, so that the plug plate 21 has a tendency to move toward the disc 85. The eccentric distance between the sliding disc 85 and the shaft 8 is adjusted by loosening the nut, so as to adjust the movement stroke of the plug plate 21, thereby controlling the single material feeding amount. The disc 85 is driven to rotate by the shaft 8, and the edge of the disc 85 abuts against the push handle 86 in cooperation with the elastic force of the spring, so that the plug plate 21 performs piston movement in the injection barrel 2, thereby realizing intermittent fixed ratio feeding. For an empty injection barrel 2, it is only necessary to slide and adjust the disc 85 to align with the center of the shaft 8. The eccentric distance between the disc 85 and the shaft 8 is zero, and the plug plate 21 remains in a fixed position without performing material guiding work.
