[0002] EVA masterbatch is an additive specially used for coloring EVA (ethylene-vinyl acetate copolymer) materials. It consists of pigment pigments and carrier resins, where the pigment pigments determine the color of the masterbatch, while the carrier resin provides good dispersibility and processability. This masterbatch can be regarded as a pigment concentrate, so its tinting power is higher than the pigment itself.
[0003] EVA masterbatch mixing device is a kind of equipment specially used to mix pigment and EVA substrate evenly. Its core purpose is to achieve efficient and stable production of masterbatch. The mixing device usually consists of multiple parts, including raw material input system, mixing chamber, temperature control system, stirring or screw mixing mechanism, exhaust system and discharge device. Each part is carefully designed to ensure that the raw materials can be evenly mixed and achieve the desired mixing effect.
[0004] At present, in the mixing process of the existing EVA masterbatch mixing device, the mixing equipment is not convenient to mix the EVA masterbatch continuously and evenly, which easily makes the color and performance of the masterbatch produced in different time periods unstable, increases the difference between different batches, and increases the downtime and the conversion time between batches, reduces the production efficiency, increases the energy consumption and production cost per unit product, and increases the production emissions, resulting in its poor environmental protection.
[0005] In view of this, the utility model provides a novel continuous environmentally friendly EVA masterbatch mixing device. Utility Model Content

[0011] As a further improvement of the present technical solution, the unloading assembly includes a support rod, which is movably connected to the inside of the support block. The support rod passes through the outer wall of the support block and is fixedly connected to a plurality of baffles. The baffles are movably connected between the unloading box and the inside of the mixing box. The unloading assembly is used to transport the masterbatch to the outer wall of the pressure roller.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] By continuously pouring the masterbatch into the discharge box, the masterbatch falls into the discharge component.

[0019] like Figure 1-3 As shown, the device comprises a material box 1, a mixing box 11 is fixedly connected to the bottom of the material box 1, support plates 110 are fixedly connected to the bottom of the mixing box 11 near both ends, and a conveying assembly 12 is movably connected between the two support plates 110;
[0020] There are two mixing components 13 in movable communication near the bottom of the mixing box 11, a gravity component 14 is movably connected between the mixing box 11 and the inner side of the outer wall of the unloading box 1, and a unloading component 15 is movably connected inside the gravity component 14, and the unloading component 15 is located between the mixing box 11 and the inner side of the unloading box 1;
[0021] First, the specific structure of the conveying assembly 12 is disclosed. The conveying assembly 12 includes two rotating rods 121, and the two rotating rods 121 are respectively movably connected between the two support plates 110 near the two ends. A conveyor belt 120 is movably connected between the outer walls of the two rotating rods 121. The conveying assembly 12 is used to convey the mixed masterbatch. The output shaft of the motor drives one of the rotating rods 121 to rotate, and the rotating rod 121 drives the conveyor belt 120 to rotate between the two rotating rods 121, so as to transport the masterbatch on the surface of the conveyor belt 120, so as to convey the mixed masterbatch out.
[0022] According to the above disclosure of the specific structure of the mixing assembly 13, the mixing assembly 13 includes a pressure roller 130, both ends of the pressure roller 130 are fixedly connected with a rotating shaft 131, the rotating shaft 131 is movably connected to the inner wall of the mixing box 11, and the pressure roller 130 is movably connected to the inner wall of the mixing box 11. The mixing assembly 13 is used to mix the masterbatch, and the rotating shaft 131 is driven by the output shaft of the motor to rotate inside the outer wall of the mixing box 11, and the rotation of the rotating shaft 131 is used to rotate the pressure roller 130, and the two pressure rollers 130 rotate in opposite directions to each other, so as to press and mix the masterbatch located between the outer walls of the two pressure rollers 130;
[0023] According to the above disclosure of the specific structure of the gravity component 14, the gravity component 14 includes a support block 140, which is movably connected to the inside of the chute between the unloading box 1 and the inner wall of the mixing box 11, and an elastic member 141 is fixedly connected between the bottom of the support block 140 and the bottom of the chute of the mixing box 11. The support block 140 is movably connected to the unloading component 15. The gravity component 14 is used to weigh the masterbatch inside the unloading component 15, and the weight of the masterbatch between the two baffles 150 is increased, thereby driving the support rod 151 and the support block 140 to exert downward pressure, so that the support block 140 forms a downward pressing and contracting force on the elastic member 141, thereby moving the support block 140 from the inside of the unloading box 1 to the inside of the mixing box 11. When the masterbatch inside the two baffles 150 is poured out, the pressure of the support rod 151 and the support block 140 on the elastic member 141 is reduced, so that the elastic member 141 rebounds and drives the support block 140 back to the inside of the unloading box 1;
[0024] According to the above disclosure of the specific structure of the blanking assembly 15, the blanking assembly 15 includes a support rod 151, the support rod 151 is movably connected to the inside of the support block 140, the support rod 151 passes through the outer wall of the support block 140 and is fixedly connected to a plurality of baffles 150, the baffles 150 are movably connected between the blanking box 1 and the inside of the mixing box 11, and the blanking assembly 15 is used to transport the masterbatch to the outer wall of the pressure roller 130, and the masterbatch is input into the inside of the lower material box 1 so that the masterbatch inside thereof falls between the two baffles 150, and the baffles 150 and the support rod 151 are interlocked. The gravity increases, and the baffle 150 is stuck in the inside of the material box 1. When the support rod 151 drives the baffle 150 to move into the mixing box 11, the baffle 150 is moved out of the inside of the material box 1, so that the baffle 150 rotates to one side under the action of gravity, driving the support rod 151 to rotate inside the support block 140, and the masterbatch inside the baffle 150 is poured out. When the gravity between the two baffles 150 is reduced, the baffle 150 is quickly reset to the inside of the material box 1 through the rebound of the support block 140, so as to facilitate the continuous reciprocating conveying of the masterbatch.
[0025] The improvement of this embodiment is that: by inputting masterbatch into the lower material box 1, the masterbatch inside it falls between the two baffles 150, the gravity between the baffle 150 and the support rod 151 is increased, and the baffle 150 is stuck in the lower material box 1. When the support rod 151 drives the baffle 150 to move into the mixing box 11, the baffle 150 is moved out from the lower material box 1, so that the baffle 150 rotates to one side under the action of gravity, driving the support rod 151 to rotate inside the support block 140, and the weight of the masterbatch between the two baffles 150 is increased, thereby driving the support rod 151 and the support block 140 to press downward, so that the support block 140 forms a downward pressing and contracting force on the elastic member 141, thereby moving the support block 140 from the lower material box 1 to the mixing box 11. When the masterbatch inside the two baffles 150 is poured out, the support rod 151 and the support block 140 are pressed downward. The pressure on the elastic member 141 is reduced, so that the elastic member 141 rebounds and drives the support block 140 back to the inside of the material box 1, and the motor output shaft drives the rotating shaft 131 to rotate inside the outer wall of the mixing box 11, and the rotation of the rotating shaft 131 is used to adjust the rotation of the pressure roller 130, and the two pressure rollers 130 rotate in opposite directions to each other, so that the masterbatch located between the outer walls of the two pressure rollers 130 is pressed and mixed, and one of the rotating rods 121 is driven to rotate by the motor output shaft, and the conveyor belt 120 is driven to rotate between the two rotating rods 121 by the rotation of the rotating rod 121, so that the masterbatch on the surface of the conveyor belt 120 is transported, so that the mixed masterbatch is transported out, and the masterbatch inside the baffle 150 is dumped out. When the gravity between the two baffles 150 is reduced, the baffle 150 is quickly reset to the inside of the material box 1 by the rebound of the support block 140, so as to facilitate the continuous reciprocating transportation of the masterbatch;
[0026] In summary, the working principle of this solution is as follows:
[0027] By continuously pouring the masterbatch into the feed box 1, the masterbatch falls into the feed assembly 15, and the weight of the feed assembly 15 is increased by the increase of the masterbatch, so that the feed assembly 15 drives the gravity assembly 14 to extend downward, so that the feed assembly 15 moves from the feed box 1 to the mixing box 11, wherein the gravity assembly 14 increases the weight of the masterbatch between the two baffles 150, thereby driving the support rod 151 and the support block 140 to exert downward pressure, so that the support block 140 forms a downward pressing and contracting force on the elastic member 141, thereby moving the support block 140 from the feed box 1 to the mixing box 11, and when the masterbatch inside the two baffles 150 is poured out, the weight of the masterbatch is increased. After that, the pressure of the support rod 151 and the support block 140 on the elastic member 141 is reduced, so that the elastic member 141 rebounds and drives the support block 140 back to the inside of the feeding box 1. When the feeding assembly 15 enters the mixing box 11, the feeding assembly 15 rotates inside the gravity assembly 14, so that the masterbatch inside the feeding assembly 15 is poured onto the outer wall of the mixing assembly 13, wherein the feeding assembly 15 inputs the masterbatch into the feeding box 1 so that the masterbatch inside it falls between the two baffles 150, and the gravity between the baffle 150 and the support rod 151 is increased. At the same time, the baffle 150 is stuck in the feeding box 1. When the support rod 151 drives the baffle 150 to move to the inside of the mixing box 11 Afterwards, since the baffle 150 is moved out from the inside of the material box 1, the baffle 150 rotates to one side under the action of gravity, driving the support rod 151 to rotate inside the support block 140, and pouring out the masterbatch inside the baffle 150. When the gravity between the two baffles 150 is reduced, the support block 140 rebounds and drives the baffle 150 to quickly return to the inside of the material box 1, so as to facilitate the continuous reciprocating conveying of the masterbatch. The masterbatch is mixed by the mixing component 13, wherein the mixing component 13 drives the rotating shaft 131 to rotate inside the outer wall of the mixing box 11 through the output shaft of the motor, and the rotation of the rotating shaft 131 drives the pressure roller 130 to rotate, and the two pressure rollers 130 rotate in opposite directions to each other. The masterbatch located between the outer walls of the two pressure rollers 130 is pressed and mixed, and the mixed masterbatch is transported out through the conveying component 12, wherein the conveying component 12 drives one of the rotating rods 121 to rotate through the motor output shaft, and the rotation of the rotating rod 121 drives the conveyor belt 120 to rotate between the two rotating rods 121, thereby transporting the masterbatch on the surface of the conveyor belt 120, and thus the mixed masterbatch is transported out. When the masterbatch inside the lowering component 15 is poured out, the weight of the lowering component 15 becomes lighter, so that the gravity component 14 rebounds and drives the lowering component 15 to reset to the inside of the lowering box 1, so that the masterbatch can be weighed and transported again, thereby ensuring the continuous operation of the mixing device.
