[0023] Please refer to Figs. 1-2 , the plastic color mixing and homogenizing tank provided by the embodiments of the present application will be described.
[0024] As Fig. 1 and Fig. 2The utility model discloses a plastic mixed color homogenizing jar, which comprises a mixed color jar 100, a spiral feeder 200, a cold air machine 300 and an air extractor 400.
[0025] The spiral feeder 200 is arranged at the center of the mixed color jar 100 and is driven by a motor to lift and feed a spiral lifting feeder screw in the middle, so that the plastic particles can be conveyed from the bottom of the spiral feeder 200 to the discharge port 210. The plastic particles discharged from the discharge port 210 will move along the turbulence baffle 220 and gradually move to the outer edge of the turbulence baffle 220. At this time, the plastic particles can be mixed and distributed during the movement due to the plurality of turbulence blocks 221, and finally fall into the accommodating cavity 110 in the mixed color jar 100 to achieve the mixing effect.
[0026] During use, the cold air machine 300 is started to input cold air from the cold air pipe 310 into the accommodating cavity 110 in the mixed color jar 100, so that the environment in the mixed color jar 100 can be cooled to avoid high temperature in the mixed color jar 100. In addition, the air extractor 400 in communication with the air outlet of the mixed color jar 100 can extract the air in the mixed color jar 100, and the cold air machine 300 forms a cold air channel to better pass the cold air through the accommodating cavity 110 in the mixed color wall for cooling and temperature reduction of the accommodating cavity 110, reduction of the temperature of the spiral feeder 200, and reduction of the temperature of the plastic particles to reduce the heat accumulation in the mixed color jar 100, avoid the situation that the plastic particles are yellow due to high temperature, the color of the plastic particles changes or the performance of the plastic particles deteriorates, and ensure the quality of the homogenized plastic particles.
[0027] The plurality of turbulence blocks 221 are arranged on the turbulence baffle 220 of the plastic color mixing homogenizing tank, so that the plastic particles are mixed during movement, which is beneficial to the dispersion and mixing of the plastic particles during homogenization, so as to improve the homogenization efficiency and reduce the color mixing time; and the cold air channel passing through the containing cavity 110 in the color mixing tank 100 is formed by the cold air machine 300 and the air extractor 400, so that the cold air cools and cools in the containing cavity 110, so as to reduce the temperature of the spiral feeder 200, reduce the temperature of the plastic particles, reduce the heat accumulation phenomenon in the color mixing tank 100, avoid the situation that the plastic particles are yellow due to high temperature, the color of the plastic particles changes or the performance deteriorates, and ensure the quality of the homogenized plastic particles.
[0028] In some embodiments of the utility model, a plurality of turbulence blocks 221 are divided into inner ring groups 222 and outer ring groups 223; a plurality of turbulence blocks 221 of the inner ring group 222 are evenly distributed around the discharge port 210; a plurality of turbulence blocks 221 of the outer ring group 223 are located between adjacent two turbulence blocks 221 of the inner ring group 222, and the distance between the turbulence block 221 of the outer ring group 223 and the discharge port 210 is greater than the distance between the inner ring group 222 and the discharge port 210. As shown in the figure, the turbulence block 221 of the inner ring group 222 contacts the plastic particles coming out of the discharge port 210 faster, therefore, the turbulence block 221 of the outer ring group 223 is located between adjacent two turbulence blocks 221 of the inner ring group 222, so as to secondarily distribute the plastic after the distribution of the turbulence block 221 of the inner ring group 222, so as to better disperse the plastic particles, improve the homogenization efficiency and reduce the color mixing time.

The feeding cylinder 230 is vertically arranged, the discharge port 210 is located at the top end, when the included angle M is less than 45°, the falling speed of the plastic particles is too fast, which cannot effectively distribute and mix the plastic particles, affecting the homogenization efficiency; when the included angle M is greater than 100°, the flow speed of the plastic particles is slow, and it is not easy to distribute, and the homogenization efficiency is greatly reduced. When the included angle M is 45-100°, the dispersion and uniformity of the plastic particles are better, so as to better improve the homogenization efficiency and reduce the color mixing time.
[0030] In some embodiments of the utility model, the lower end of the feeding cylinder 230 extends to the outside of the bottom of the color mixing tank 100, and the lower end of the feeding cylinder 230 is provided with a feeding port 231 arranged upward.

When the plastic particles in the color mixing tank 100 are not uniformly mixed, the reflux port 120 is opened, and the plastic particles are conveyed from the reflux port 120 to the feeding port 231, so that the spiral feeder 200 can re-convey the plastic particles that are not uniformly mixed to the discharge port 210, and then the plastic particles are mixed by the turbulence baffle 220, and the cycle is repeated, so that the plastic particles can be uniformly mixed. The uniformly mixed plastic particles can be conveyed to the finished product through the opened discharge port 130. It should be noted that when the plastic particles are not uniformly mixed, the discharge port 130 is closed to prevent the plastic particles that are not uniformly mixed from being conveyed to the finished product.

[0035] In some embodiments of the utility model, in order to better manage the discharged wind, the air extractor 400 further has a draught pipe 410, the draught pipe 410 is communicated with the draught outlet of the air extractor 400, the draught pipe 410 can be directly sent to the workshop outside or communicated with the cold air fan 300, so as to carry out air circulation, most preferably, the outlet of the draught pipe 410 is sleeved with a dust removal filter bag 420, so as to filter air by the dust removal filter bag 420, to collect dust in the air of containing cavity 110, to avoid dust pollution workshop or surrounding air environment.
[0036] The above is only the preferred embodiment of the utility model, it should be pointed out, for ordinary technical personnel in the prior art, under the premise of not departing from the technical principle of the utility model, can also make a number of improvements and substitutions, these improvements and substitutions also should be considered the protection scope of the utility model.
