[0003] The antistatic performance of PVC particles is unstable due to fluctuations in the addition amount of the antistatic agent, thus reducing the qualification rate and affecting consistency. Different products have different requirements for antistatic performance, and it has been difficult to meet the diverse production requirements in the past. Summary of the Invention

[0004] The present invention discloses an antistatic PVC particle preparation device and process, aiming to solve the technical problems in the background art that the antistatic property of PVC particles is unstable due to fluctuations in the dosage of the antistatic agent, resulting in a low qualification rate and poor consistency, and diverse requirements, which are difficult to meet in the past.

[0005] An antistatic PVC particle preparation device proposed by the present invention includes a preparation machine. A preparation motor is fixedly connected to the front end of the preparation machine. The power output shaft of the preparation motor is connected to a heating rod through a coupling. The heating rod is located inside the preparation machine. Stirring rods are fixedly connected to the outer side of the heating rod. A round hole is opened at the top of the preparation machine. A particle discharging cylinder is fixedly connected to the top of the round hole. A perforation is opened at the top of the preparation machine. A feeding cylinder is fixedly connected to the top of the perforation. And a quantitative placing component is arranged at the top of the feeding cylinder. A discharging component is arranged at the bottom of the quantitative placing component. A discharging round hole plate is arranged at the front end of the preparation machine. A cutting knife is arranged at the front end of the discharging round hole plate; The quantitative placing component includes a feeding cylinder. Symmetrical quantitative cylinders are movably connected to the bottom of the feeding cylinder. And the discharging components are all located inside the quantitative cylinders; The discharging component includes a switching plate. A fixed rod is movably connected to the inside of the switching plate. And a linkage plate is movably connected to the outer side of the fixed rod.

[0006] In a preferred embodiment, the quantitative placement component further includes a driving motor. The power output shaft of the driving motor is connected to a rotating shaft through a coupling, and the bottom end of the rotating shaft is movably connected to the top end of the preparation machine. A belt is movably connected to the outside of the rotating shaft, and a semi-gear shaft is movably connected to the inside of the belt. A rotating gear is movably connected to the outside of the semi-gear shaft, and the rotating gear and the semi-gear shaft are meshed through a tooth groove. A linkage rod is fixedly connected to the inside of the rotating gear, and the bottom end of the linkage rod is movably connected to the top end of the preparation machine, and the top end of the linkage rod is fixedly connected to a fixed circular frame. Symmetrical holes are provided on the fixed circular frame, and the outside of the quantitative cylinder is fixedly connected between the holes. The bottom end of the quantitative cylinder is movably connected to the top end of the feeding cylinder. A connecting frame is fixedly connected to the top end of the feeding cylinder, a servo motor is fixedly connected to the top end of the connecting frame, the power output shaft of the servo motor is connected to a stirring frame through a coupling, and the stirring frame is located inside the feeding cylinder. A plurality of scraping plates are fixedly connected to the outside of the stirring frame, and the outside of the scraping plates is in contact with the inner wall of the feeding cylinder.

[0007] By providing a quantitative placement component, when preparing PVC particles, the antistatic agent is added to the feeding cylinder. The servo motor is started to drive the stirring frame to rotate in the feeding cylinder. The plurality of scraping plates on the outside of the stirring frame rotate with the stirring frame, and the outside of the scraping plates is in contact with the inner wall of the feeding cylinder, so that the antistatic agent is preliminarily mixed evenly in the feeding cylinder. Then the driving motor is started to drive the rotating shaft to rotate, and the belt on the outside of the rotating shaft moves accordingly, thereby driving the semi-gear shaft to rotate. During the rotation process, since only part of the semi-gear shaft has teeth, the rotating gear will rotate intermittently. The linkage rod fixedly connected to the inside of the rotating gear rotates with the rotating gear, and the fixed circular frame fixed to the top end of the linkage rod also rotates accordingly. Since the outside of the quantitative cylinder is located in the holes of the fixed circular frame and is fixedly connected, the quantitative cylinder will perform a circular motion centered on the linkage rod. During the circular motion of the quantitative cylinder, when the quantitative cylinder moves to the corresponding position at the bottom end of the feeding cylinder, the bottom end of the feeding cylinder automatically opens, and materials such as the antistatic agent fall into the quantitative cylinder by gravity, realizing quantitative loading. After loading the antistatic agent, as the fixed circular frame continues to rotate, when the quantitative cylinder rotates to the position at the top end of the lower feeding cylinder, the bottom end of the quantitative cylinder opens, and the antistatic agent falls from the quantitative cylinder into the feeding cylinder, and then enters the PVC particle preparation link, completing the process of quantitatively adding the antistatic agent during the preparation of PVC particles, accurately controlling the addition amount of the antistatic agent, stabilizing the antistatic performance of PVC particles, avoiding product performance fluctuations caused by improper addition amounts, and improving the product qualification rate and consistency. It can also flexibly adjust the dosage according to different antistatic requirements to meet diversified production.

[0008] In a preferred embodiment, the discharging assembly further includes symmetric connecting seats, which are fixedly connected between the opposite sides of the connecting seats and the outer side of the metering cylinder. Openings are provided on both the connecting seats and the metering cylinder. The fixed rod is located inside the opening, and both the opening and closing plate and the linkage plate are movably connected inside the opening. A rotating seat is fixedly connected to the front end of the opening and closing plate, and a linkage seat is fixedly connected to the front end of the linkage plate.

Moreover, mounting parts are fixedly connected to the tops of the electric telescopic rods, and the tops of the mounting parts are fixedly connected to the bottom ends of the fixed circular frames.

[0009] By providing the discharging assembly, when the metering cylinder rotates with the fixed circular frame to quantitatively add the antistatic agent, the electric telescopic rod contracts, the opening and closing plate closes on the fixed rod, is in close contact with the inner side of the metering cylinder, closes the bottom to receive the antistatic agent to complete quantitative loading, and the linkage plate cooperates to maintain the closure. When the metering cylinder rotates above the feeding cylinder, the electric telescopic rod extends, pushing the pulling seat, the fixed plate, and the movable frame to descend, driving the connecting rod, causing the linkage plate and the opening and closing plate to rotate around the fixed rod to open, and the antistatic agent falls into the feeding cylinder to complete the addition, and then returns to the closed state. The metering cylinder continues to rotate to prepare for the next operation, realizing precise control of the opening and closing degree and time of the opening and closing plate by the electric telescopic rod, ensuring that the antistatic agent in the metering cylinder falls into the feeding cylinder accurately and stably each time, guaranteeing the high precision of the added amount, and improving the stability of the antistatic performance of the PVC particles.

[0011] A method for using an antistatic PVC particle preparation device, using an antistatic PVC particle preparation device as described above, includes the following steps: Step 1: The PVC raw material enters the preparation machine through the round hole at the top of the granulating cylinder. The preparation motor drives the heating rod, which drives the stirring rod to stir and heat-melt the PVC raw material. Step 2: During the melting and stirring process, the antistatic agent is placed in the feeding cylinder. The bottom end of the feeding cylinder automatically opens and closes to achieve quantitative loading of the antistatic agent into the metering cylinder. The metering cylinder moves to directly above the feeding cylinder. Step 3: The opening and closing plate at the bottom end of the metering cylinder cooperates with the linkage plate to put the antistatic agent into the preparation machine through the feeding cylinder, and stir and fuse it with the melted PVC raw material.
