[0002] Masterbatch is the full name of plastic masterbatch, also known as masterbatch. It is a kind of plastic processing aid developed in the 1980s. It refers to the granular material obtained by mixing and kneading various additives, fillers and a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation, and then through the process of metering, mixing, melting, extrusion, pelletizing and other processing of equipment such as extruders.

[0051] A driving mechanism 5, wherein the driving mechanism 5 is mounted on the density adjusting mechanism 4;

[0052] The driving mechanism 5 includes a motor 51 fixed to one side of the storage box 411, and a gear 52 is fixed to one end of the output shaft of the motor 51. One side of the gear 52 is meshed with the one-way gear 27, and the other side of the gear 52 is meshed with the one-way gear 2 4219.

[0053] A controller is fixed to one side of the base 11 , and the controller is electrically connected to the motor 51 , the pressure sensor, the push rod motor 417 and the heater 23 .

[0054] Working principle:

[0055] The controller starts the motor 51 to drive the gear 1 52 to rotate in reverse. The reverse rotation of the gear 1 52 satisfies the direction of the rotation of the one-way gear 2 4219 to drive the rotating shaft 4 4218. The rotating shaft 4218 drives the bevel gear 2 4217, the rotating shaft 3 4215, the slide 4216, the slider and the bevel gear 3 4221 to rotate through the bevel gear 1 4220. The rotation of the bevel gear 3 4221 drives the bevel gear 4 4213, the rotating shaft 2 4211 and the gear 4 4212 to rotate. The rotation of the gear 4 4212 drives the gear 5 427 and the double-stage reciprocating threaded rod 426 to rotate. The rotation of the double-stage reciprocating threaded rod 426 causes the two moving plates 425 to push the adjusting plate 424 closer, thereby closing the forming plate 423.

[0056] Then the motor 51 is started to drive the gear 1 52 to rotate forward. The forward rotation of the gear 1 52 satisfies the direction of the rotation of the one-way gear 1 27 to drive the shaft 1 25. The shaft 1 25 drives the gear 3 24 to rotate. The rotation of the gear 3 24 drives the gear 2 26 to rotate. The rotation of the gear 2 26 drives the auger 22 to rotate and push the plastic particles leaked into the feeding barrel 21 by the unloading mechanism 3 toward the direction of the density adjustment mechanism 4. During the process, the plastic is heated by the heater 23. The melted plastic is pushed into the storage box 411 and then falls on the top of the piston plate 414. The pressure sensor obtains the pressure data and transmits it to the controller. When the material in the storage box 411 is full, the material will continue to be filled. After reaching the specified pressure discharge value, the motor 51 is started to drive the gear 52 to reverse, so that the moving plate 425 that moves to the tail of the reciprocating thread pulls the adjusting plate 424 to return to its original position, opens the multiple discharge holes of the molding plate 423, and then the material will be formed through the discharge holes. The mixed melt mechanism 2 always feeds the material into the storage box 411, and the pressure sensor always detects the pressure. If the pressure becomes smaller, it means that the material is not discharged evenly at the feeding position, which leads to uneven feeding. The smaller the pressure, the smaller the discharge speed and the smaller the molding density. At this time, the adjusting mechanism 41 is started to squeeze the plastic melt from the bottom to make its pressure reach the standard. The specific steps are as follows First, the push rod motor 417 pushes the piston plate 414, the C-shaped baffle plate 412, the discharge barrel 415, the adjustment plate 424, the hollow plate 421, the forming plate 423, the mounting plate 429, the moving plate 425, the double-stage reciprocating threaded rod 426, the gear five 427, the guide rod 428, the fixed plate 4210, the rotating shaft two 4211, the gear four 4212 and the bevel gear four 4213 to move upward, and the bevel gear four 4213 moves upward, which pushes the bevel gear three 4221 located above to move upward, so that the bevel gear four 4213 is always meshed with the bevel gear three 4221, and the piston plate 414 and the C-shaped baffle plate 412 move upward to reduce the space in the storage box 411, thereby Increasing the pressure of the internal plastic melt, pressure compensation can ensure the discharge speed and discharge density, and ensure the consistency of subsequent molding. At the same time, the internal material can be accumulated to the specified pressure by adjusting the discharge amount to ensure the molding speed and density. When adjusting, the motor 51 is started to drive the gear 1 52 to reverse, so that the adjustment plate 424 moves back and forth, and the discharge hole on the molding plate 423 is blocked, thereby reducing the discharge amount and ensuring the discharge speed and density. The above density refers to the compactness of the material. When the material supply is continuously insufficient, the adjustment mechanism 1 41 and the adjustment mechanism 2 42 are used in combination to ensure the stability of the pressure when the feeding waiting time is extended.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
