[0007] Furthermore, an exhaust pipe is fixedly connected to the top front side of the input channel, and the exhaust pipe branches to both sides in a T-shape; an input motor is fixedly installed at the front end of the input bucket, and a screw propeller A is fixedly installed at the shaft end of the input motor.
[0008] Furthermore, the propeller A consists of three sets of non-contacting spiral fins, with the outer surface of the spiral fins fitting against the inner wall of the input channel.
[0009] Furthermore, a heating wire frame is fixedly provided at the rear end of the input channel, and an air intake fan is provided at the rear end of the heating wire frame.
[0010] Furthermore, the speed limiting chamber is internally equipped with a ring-shaped impeller, and a delivery motor is fixedly installed at the rear end of the speed limiting chamber.

[0025] Example 1:
[0026] As attached Figure 1 To be continued Figure 5 As shown:
[0027] This utility model provides a continuous internal mixing production device for color masterbatch, including an input channel 1, an input hopper 101 integrally installed on the top front side of the input channel 1; a heating chamber 2 with a built-in heater is branched and connected to the bottom rear side of the input channel 1, the bottom of the heating chamber 2 has a conical structure, and a speed limiting chamber 3 is connected to the bottom of the heating chamber 2; an output channel 4, the top rear side of the output channel 4 is connected to the bottom middle of the speed limiting chamber 3; an output pipe 404 integrally installed at the front end of the output channel 4, an output motor 5 is fixedly installed at the top of the output pipe 404; a screw propeller C501 is fixedly connected to the shaft end of the output motor 5, a particle divider 502 is fixedly connected to the bottom end of the screw propeller C501, and a particle divider 502 has through-holes 503 distributed around the particle divider 502; a shielding ring 405 is fixedly installed at the lower inside of the output pipe 404; the top edge of the particle divider 502 has a flange structure, and the shielding ring 405 covers the flange structure of the particle divider 502.
[0028] Among them, an exhaust pipe 102 is fixedly connected to the top front side of the input channel 1, and the exhaust pipe 102 branches to both sides in a T shape; an input motor 103 is fixedly installed at the front end of the input bucket 101, and a screw propeller A104 is fixedly installed at the shaft end of the input motor 103.
[0029] The propeller A104 consists of three sets of non-contacting spiral fins, with the outer surface of the spiral fins fitting against the inner wall of the input channel 1.
[0030] A heating wire frame 105 is fixedly installed at the rear end of the input channel 1, and an air intake fan 106 is installed at the rear end of the heating wire frame 105.
[0031] The speed limiting chamber 3 has an internal rotating ring-finned impeller 301, and a delivery motor 302 is fixedly installed at the rear end of the speed limiting chamber 3. The delivery motor 302 is connected to the ring-finned impeller 301 for transmission. The outer middle of the ring-finned impeller 301 has a concave structure and is surrounded by equidistantly integrated fins. The outer periphery of the ring-finned impeller 301 is attached to the inner wall of the speed limiting chamber 3.
[0032] The output channel 4 has a frame 401 fixedly installed on the front side inside, and a screw propeller B402 is rotatably installed in the output channel 4, with the front end of the screw propeller B402 rotating in the frame 401; a conveyor motor 403 is fixedly installed at the rear end of the output channel 4, and the conveyor motor 403 is connected to the screw propeller B402 in a transmission connection.
[0033] Among them, a cutter 6 is fixedly installed at the bottom of the output tube 404. The cutter 6 consists of two sets of centrally symmetrical wedge-shaped blades, and the top of the cutter 6 is attached to the bottom of the particle divider 502.
[0034] like Figures 1-5 As shown, this work process can be divided into three stages;
[0035] Raw material pretreatment stage:
[0036] After cleaning, the raw materials are fed into the input hopper 101 and fall to the bottom through the input channel 1. The input motor 103 is started to drive the screw propeller A104 to rotate, pushing the raw materials backward to the heating chamber 2; at the same time, the heating wire frame 105 and the air intake fan 106 are turned on to deliver hot air forward. When the hot air is discharged through the exhaust pipe 102, it forms a reverse hot airflow, which continuously dries the raw materials and improves the subsequent preparation effect.
[0037] Heating, mixing and conveying stage:
[0038] If a heating preparation process is used, the raw materials are melted into a liquid state by the heater in the heating chamber 2. The feeding motor 302 is started to drive the ring-fin impeller 301 to rotate, gradually pushing the liquid material to the output channel 4. Then, the conveying motor 403 is started to drive the screw propeller B402 to push the liquid material to the granulation mechanism through the output pipe 404; at the same time, the output motor 5 is started to drive the screw propeller C501, so that the liquid material is discharged through the granulation hole 503.
[0039] Particle forming stage:
[0040] The pelletizer 502 and the pelletizing hole 503 rotate synchronously. After the liquid material is extruded, it contacts the cutter 6 and is cut into granules, thus completing the production of color masterbatch.
[0041] Example 2:
[0042] Based on Example 1, if conventional chemical or physical methods are used for preparation, there is no need to activate the heating function of heating chamber 2. The remaining raw material transportation and granulation processes can be carried out according to the aforementioned steps.
[0043] The specific usage and function of this embodiment are as follows:
[0044] In this invention, after the raw materials are cleaned, they are put into the input hopper 101 and fall into the input channel 1. The input motor 103 is started to drive the screw propeller A104 to rotate, and the screw propeller A104 is used to push the raw materials backward so that they finally fall into the heating chamber 2. During this process, the heating wire frame 105 and the air intake fan 106 are started to deliver hot air forward. The hot air is discharged from the exhaust pipe 102 and provides hot air flow in the opposite direction to continuously dry the raw materials and improve the preparation effect.
[0045] During heating preparation, the raw materials can be directly heated and melted by the heater in the heating chamber 2, mixed and prepared into a liquid. The feeding motor 302 is started to drive the ring-fin impeller 301 to rotate, and the liquid material is gradually conveyed downward into the output channel 4. The conveying motor 403 is started to drive the screw propeller B402 to rotate, and the liquid material is fed into the output pipe 404. The output motor 5 is started to drive the screw propeller C501 to rotate, and the liquid material is conveyed downward and discharged through the particle pore 503, thus completing the production.
[0046] The pellet separator 502 and the pellet passage 503 rotate to allow the extruded particles to contact the cutter 6 and be cut by it, thus producing particles.
[0047] In conventional chemical preparation or preparation using physical properties, the same method is followed, except that the heating function does not need to be activated. The heating chamber 2 is used as a conventional reaction vessel for mixing, and the preparation can be carried out. The flow rate can be limited by the ring-finned impeller 301 to ensure that the raw materials remain in the heating chamber 2.
