[0002] PVC stabilizers are additives used to improve the thermal stability of polyvinyl chloride (PVC) and its copolymers. PVC and its copolymers are heat-sensitive resins that readily release hydrogen chloride during heat processing, leading to thermal aging and degradation. Therefore, the main function of PVC stabilizers is to delay or prevent plastic damage and further degradation caused by heat.

[0003] Conventional grinding equipment is limited by its processing structure and requires a long processing time when handling materials, which affects processing efficiency and interferes with the grinding effect. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency grinding device for the preparation of PVC stabilizers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency grinding device for preparing PVC stabilizer, comprising a first grinding chamber and a circulation component. The bottom of the first grinding chamber is connected to a second grinding chamber. The upper and lower ends of the circulation component are respectively connected to the top of the first grinding chamber and the bottom of the second grinding chamber. Grinding components are horizontally installed inside both the first and second grinding chambers, and one end of the grinding components is connected to a drive component. The circulation component includes a circulation pump, a first combined pipe, and a second combined pipe. The top of the circulation pump is connected to the first combined pipe through a flange structure, and the bottom of the circulation pump is connected to the second combined pipe through a flange structure.

[0006] Furthermore, the first grinding chamber includes a processing chamber, an inlet / outlet valve pipe, a first connecting valve pipe, and a second connecting valve pipe. The inlet / outlet valve pipe is installed in the middle of the top of the processing chamber, and the first connecting valve pipe is provided on both the left and right sides of the processing chamber. The second connecting valve pipe is installed at the bottom of the processing chamber.

[0007] Furthermore, the second grinding chamber and the first grinding chamber adopt the same structural configuration, and the second grinding chamber and the first grinding chamber are mirror images of each other.

[0008] Furthermore, the first grinding chamber and the second grinding chamber are connected to each other via a second connecting valve pipe and flange structure on their respective sides, and the first combined pipe and the second combined pipe are connected to the first connecting valve pipe on one side of the first grinding chamber and the second grinding chamber via flange structures.

[0009] Furthermore, the grinding assembly includes a grinding roller, a first planetary drive seat, a drive shaft, and a second planetary drive seat. One end of the grinding roller is connected to and installed with the first planetary drive seat, and the drive shaft is horizontally installed at the end of the first planetary drive seat away from the grinding roller. The second planetary drive seat is installed at the end of the grinding roller away from the first planetary drive seat.

[0010] Furthermore, the first planetary drive seat and the second planetary drive seat have the same structure, and the grinding rollers are arranged in a circular array with the first planetary drive seat as the center, and there are three sets of them.

[0011] Furthermore, the drive assembly includes a mounting base, a stabilizer, and a servo motor. The stabilizer is mounted on the side of the mounting base away from the grinding assembly, and the servo motor is horizontally mounted on the side of the stabilizer away from the mounting base.

[0012] Furthermore, the side of the combined base away from the stabilizer is connected to the drive shaft, and the axis of the combined base is connected to the power output end of the servo motor.

[0013] This invention provides a high-efficiency grinding device for preparing PVC stabilizers, which has the following advantages:

[0014] 1. This utility model features symmetrically arranged circulation components at both ends of the first and second grinding chambers. A first combined pipe is connected to a first connecting valve pipe on one side of the first grinding chamber, and a second combined pipe is connected to a second connecting valve pipe on one side of the second grinding chamber. This interconnects the interiors of the two processing chambers. As needed, materials transported from the first grinding chamber to the second grinding chamber can be processed. Then, with the operation of a circulation pump, the materials from the second grinding chamber are transported back to the first grinding chamber for further grinding. This structure allows for the cyclical transport of materials within the first and second grinding chambers, ensuring efficient material processing while allowing for repeated processing. This avoids insufficient grinding and ensures the practicality of the device, preventing situations where materials are not properly processed.

[0015] 2. This utility model features grinding components installed inside the first and second grinding chambers. Grinding rollers are horizontally mounted between a first planetary transmission seat and a second planetary transmission seat with a triangular structure. A servo motor drives the first planetary transmission seat via a transmission shaft, causing the three grinding rollers to rotate horizontally. This rotation of the three grinding rollers thoroughly crushes the material, achieving the grinding operation. This structural design, combined with the use of the first and second grinding chambers, ensures thorough grinding. Furthermore, the first and second grinding chambers can be connected and fixed via flanges between the first and second connecting valve pipes on their respective upper and lower sides. This allows for the combination of the first and second grinding chambers, which contain the grinding components, and the addition of a circulation component, enabling structural expansion. This allows for different configurations of the entire device to meet various processing requirements. Attached Figure Description

[0024] like Figures 1 to 6 As shown, a high-efficiency grinding device for preparing PVC stabilizer includes a first grinding chamber 1 and a circulation component 3. The bottom of the first grinding chamber 1 is connected to a second grinding chamber 2. The upper and lower ends of the circulation component 3 are respectively connected to the top of the first grinding chamber 1 and the bottom of the second grinding chamber 2. Grinding components 4 are horizontally installed inside both the first grinding chamber 1 and the second grinding chamber 2, and one end of the grinding component 4 is connected to a drive component 5. The circulation component 3 includes a circulation pump 301, a first combined pipe 302 and a second combined pipe 303. The top of the circulation pump 301 is connected to the first combined pipe 302 through a flange structure, and the bottom of the circulation pump 301 is connected to the second combined pipe 303 through a flange structure. The first grinding chamber 1 includes a processing chamber 101, an inlet / outlet valve pipe 102, a first connecting valve pipe 103 and a second connecting valve pipe 104. The inlet / outlet valve pipe 104 is installed in the middle of the top of the processing chamber 101. 2. The processing chamber 101 is provided with first connecting valve pipes 103 on both the left and right sides, and a second connecting valve pipe 104 is installed at the bottom of the processing chamber 101. The second grinding chamber 2 and the first grinding chamber 1 adopt the same structure and are mirror images of each other. The first grinding chamber 1 and the second grinding chamber 2 are connected to each other by the second connecting valve pipe 104 on each side and the flange structure. The first combined pipe 302 and the second combined pipe 303 are connected to the first connecting valve pipe 103 on one side of the first grinding chamber 1 and the second grinding chamber 2 respectively by the flange structure. As needed, the material inside the first grinding chamber 1 can be transported to the inside of the second grinding chamber 2. After processing, with the operation of the circulating pump 301, the material inside the second grinding chamber 2 can be transported back to the inside of the first grinding chamber 1 for another grinding process.

[0025] like Figures 1 to 6As shown, the grinding assembly 4 includes a grinding roller 401, a first planetary drive seat 402, a drive shaft 403, and a second planetary drive seat 404. One end of the grinding roller 401 is connected to and mounted with the first planetary drive seat 402, and the drive shaft 403 is horizontally mounted on the end of the first planetary drive seat 402 away from the grinding roller 401. The second planetary drive seat 404 is mounted on the end of the grinding roller 401 away from the first planetary drive seat 402. The first planetary drive seat 402 and the second planetary drive seat 404 have identical structures. The grinding roller 401 is arranged in a circular array with the first planetary drive seat 402 as the center, and three groups are distributed thereon. The drive assembly 5 includes a combination seat 5. 01. A stabilizer 502 and a servo motor 503 are installed on the side of the assembly 501 away from the grinding component 4.

Under the operation of the servo motor 503, the first planetary transmission seat 402 is driven to operate through the drive shaft 403, thereby driving the three sets of grinding rollers 401 to rotate in the horizontal direction. Under the rotation of the three sets of grinding rollers 401, the material is fully crushed.

[0026] In summary, as Figures 1 to 6 As shown, the high-efficiency grinding device for PVC stabilizer preparation is used by first injecting the material to be processed into the processing chamber 101 through the inlet / outlet valve pipe 102 in the first grinding chamber 1. At this time, the drive components 5 on one side of the first grinding chamber 1 and the second grinding chamber 2 start to operate. As the servo motor 503 on one side of the stabilizer 502 starts to operate, it drives the first planetary transmission seat 402 on one side of the combination seat 501 to operate synchronously through the transmission shaft 403 connected to the servo motor 503. Under the cooperative operation of the first planetary transmission seat 402 and the second planetary transmission seat 404, the three sets of grinding rollers 401 start to rotate synchronously, thereby crushing and grinding the material entering the first grinding chamber 1.

[0027] The material processed in the first grinding chamber 1 is then transported to the interior of the second grinding chamber 2 via the first connecting valve pipe 103 and the second connecting valve pipe 104 used for connecting the assembly. Inside the second grinding chamber 2, the grinding assembly 4, in conjunction with the drive assembly 5, performs another grinding process. Then, as needed, the circulation component 3 connected to the top of the first grinding chamber 1 and the bottom of the second grinding chamber 2 is activated. Under the operation of the circulation pump 301, and in conjunction with the conveying of the first combined pipe 302 and the second combined pipe 303, the material inside the second grinding chamber 2 is transported back to the interior of the first grinding chamber 1. This process is repeated to ensure the processing quality.
