[0026] The following is combined with Figure 1-6 To further explain this application,

[0027] The embodiment of the present application discloses a raw material pretreatment device for a plastic grinding mill. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , a raw material pretreatment device for a plastic grinding mill, comprising a box body 1, a quantitative feeding mechanism 2 is provided on one side of the box body 1, two positioning frames 3 are fixedly connected to one side of the box body 1, the inner cavity of the positioning frame 3 is connected to the inner cavity of the box body 1, a fan 4 is fixedly installed in the inner cavity of the positioning frame 3, and the number of fans 4 is several. A positioning shell 5 is fixedly connected to the other side of the box body 1, a blanking shell 6 is fixedly installed at the bottom of the inner cavity of the box body 1, and a filter plate 7 is fixedly installed in the inner cavity of the blanking shell 6;

[0028] The quantitative feeding mechanism 2 includes a feeding shell 201 and a first motor 206. The feeding shell 201 is fixedly installed on one side of the box body 1. One side of the feeding shell 201 is fixedly connected to the hopper 202. The top of the feeding shell 201 is fixedly connected to the second motor 203. The output end of the second motor 203 passes through the inner cavity of the feeding shell 201 and is fixedly connected to the spiral conveying rod 204. One end of the spiral conveying rod 204 is rotatably connected to the inner wall of the feeding shell 201 through a bearing. The other side of the feeding shell 201 is fixedly connected to the guide shell 205. The bottom of the guide shell 205 is fixedly connected to the top of the box body 1. 5 is connected with the inner cavity of the box body 1, the first motor 206 is fixedly installed on the surface of the box body 1, the output end of the first motor 206 passes through the inner cavity of the box body 1 and is fixedly connected with a roller 207, one end of the roller 207 is rotatably connected to the inner wall of the box body 1 through a bearing, and a diversion groove 208 is provided on the surface of the roller 207; by setting the quantitative feeding mechanism 2, the feeding amount of the plastic particles can be limited, which is conducive to the fan 4 to blow and remove impurities from the plastic particles, and after the impurity-removed plastic particles fall into the inner cavity of the discharge shell 6, the filter plate 7 inside it can be used to screen the smaller plastic particles.

[0029] Reference Figure 4The surface of the first motor 206 is fixed with a positioning ring 209, and one side of the positioning ring 209 is fixedly connected to the surface of the box body 1; by providing the positioning ring 209, the first motor 206 can be fixed to prevent the first motor 206 from falling off during use.

[0030] Reference Figure 2 and Figure 3 A support frame 210 is fixedly installed on the surface of the loading shell 201, and one side of the support frame 210 is fixedly connected to the surface of the box body 1; by setting the support frame 210, the loading shell 201 can be supported and fixed to prevent the position of the loading shell 201 from shifting during use.

[0031] Reference Figure 2 、 Figure 3 and Figure 4 A material guide frame 8 is fixedly installed in the inner cavity of the box body 1, and the material guide frame 8 is sleeved on the outside of the roller 207; by setting the material guide frame 8, the roller 207 can be limited to avoid the plastic particles in the inner cavity of multiple diversion grooves 208 being discharged at the same time when the roller 207 rotates. At the same time, since the surface of the roller 207 contacts the inner wall of the material guide frame 8, it can play a role in quantitative discharge.

[0032] Reference Figure 5 The inner cavity of the positioning frame 3 is fixedly installed with a filter screen 9, and the filter screen 9 is arranged on one side of the fan 4; by setting the filter screen 9, the box body 1 can be dustproof, preventing dust from entering the inner cavity of the box body 1 and causing pollution to the plastic particles.

[0033] Reference Figure 5 Two guide plates 10 are fixedly installed in the inner cavity of the box body 1. The two guide plates 10 are arranged in an opposite and staggered manner. The two guide plates 10 are arranged between the two positioning frames 3. By setting the guide plates 10, the plastic particles can be decelerated and the impurity removal quality of the fan 4 for the plastic particles can be improved.

[0034] Reference Figure 2 and Figure 5 A guide shell 11 is fixedly installed in the inner cavity of the box body 1, and the guide shell 11 is arranged at the bottom of the guide plate 10; by setting the guide shell 11, the plastic particles after impurities removal can be guided, and at the same time, the conical guide shell 11 can slow down the plastic particles when they fall.

[0035] Working principle: When in use, the staff pours the plastic particles into the inner cavity of the hopper 202, and then uses the external control switch to start the first motor 206 and the second motor 203. The output end of the second motor 203 drives the spiral conveying rod 204 to rotate, which can transport the plastic particles in the inner cavity of the upper shell 201. After the plastic particles are transported to the specified height, they fall into the inner cavity of the diverter trough 208 through the guide shell 205. At this time, driven by the first motor 206, the roller 207 is rotated, and the roller 207 drives the plastic particles in the inner cavity of the diverter trough 208 to move when rotating. Since the surface of the roller 207 is in contact with the inner wall of the guide frame 8, when the roller 207 rotates, the guide frame 8 can remove excess plastic particles, so that the plastic particles in the inner cavity of each diverter trough 208 are the same, thereby achieving the effect of quantitative discharging. When the diverter trough 208 is perpendicular to the bottom of the guide frame 8, the plastic particles fall downward. During the falling process, the fan 4 blows air to the inner cavity of the box body 1, which can blow the fine impurities in the plastic particles to the positioning shell 5. After being removed by the upper fan 4, the plastic particles fall downward to the surface of the guide plate 10. The oppositely arranged guide plate 10 is used to guide and decelerate the plastic particles, which helps the lower fan 4 to blow air and remove impurities from the plastic particles. After the impurity removal is completed, the plastic particles fall into the inner cavity of the guide shell 11. The conical guide shell 11 is used to decelerate the plastic particles again and make them fall into the inner cavity of the discharge shell 6. The inner cavity of the discharge shell 6 is installed with a filter plate 7 with an inclined angle. When the plastic particles roll along the filter plate 7, the smaller plastic particles will fall into the inner cavity of the discharge shell 6 through the through holes on the surface of the filter plate 7, thereby realizing the screening of the plastic particles.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
