[0002] In the process of blending and making plastic master batch, plastic powder (i.e. master batch) is mixed with different types of additives and stirred fully, and then extruded into different proportions of plastic master batch after heating, so as to obtain plastic master batch with different properties. In the use process, these modified plastic master batches are added into injection molding machines or other plastics for use.

[0003] In the prior art, in the process of producing plastic master batch, the plastic powder after stirring and blending is conveyed into a heating pipe for heating and stirring, and then extruded into a shape. The heating pipe is provided with an exhaust hole. Water vapor is generated when the moisture in the mixed plastic master batch expands in the heating pipe. The expanded water vapor is discharged from the exhaust hole. Since the mixed plastic powder generates some resin substances after heating, which are mixed in the water vapor and discharged from the exhaust hole, the resin substances are sticky and easy to block the exhaust hole. When the exhaust hole is blocked, the water vapor cannot be discharged, which affects the performance of the plastic master batch. Therefore, after the heating pipe is used for a period of time, the worker needs to pay attention to the exhaust condition of the discharge hole.

DETAILED DESCRIPTION

[0022] In Figure 1 In the prior art shown in the figure, in the production of plastic master batch, the mixed plastic powder needs to be transported into the heating pipe 4 for heating and stirring, and then extruded and formed from the discharge port 5. The drive motor 1 controls the rotation of the screw shaft 2, the threaded push rod of the screw shaft 2 rotates in the heating pipe 4, the mixed plastic powder is transported into the heating pipe 4 from the feed port 3, and the threaded push rod moves the plastic powder from the feed port 3 end to the rear end. The moisture in the mixed plastic master batch will produce water vapor when heated in the heating pipe 4, and the water vapor will be discharged from the exhaust hole 6. Since the mixed plastic powder will produce some resin substances after heating, which will be mixed in the water vapor and discharged from the exhaust hole, these resin substances are sticky and easy to block the exhaust hole 6. After the heating pipe 4 is used for a period of time (5-7 hours), the worker needs to pay attention to the exhaust condition of the exhaust hole 6. When the exhaust amount is small or is about to be blocked, the worker needs to use an iron wire to dredge the exhaust hole 6. There is a problem of manually dredging the exhaust hole 6, and sometimes the worker is too busy to remember to dredge the exhaust hole 6, which causes the moisture in the plastic master batch to be unable to be discharged, affecting the quality of the finished product, and there is a certain deficiency.
