[0002] Filler masterbatch refers to the granules and powders obtained by mixing and kneading various required additives and fillers with a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation. The masterbatch is composed of carrier resin, fillers and various additives. The limit of additives or filler content in the masterbatch is several to dozens of times higher than the required amount in the actual plastic product. In the molding process, the ratio of masterbatch to base resin must be adjusted according to the content of relevant components in the masterbatch and the amount to be added in the actual product. Masterbatch can usually be divided into ordinary filler masterbatch (referred to as filler masterbatch) and functional masterbatch, such as color masterbatch, anti-drip masterbatch, etc. The main component of filler masterbatch is filler, which is mainly used for the processing and molding of polyolefins (polyethylene and polypropylene), also known as polyolefin filler masterbatch. In the preparation process of highly filled PE film special masterbatch, an extruder needs to be used for extrusion molding. However, the existing extruder 1 does not have the function of material The function of storage is performed, and the feeding method is usually manual feeding, which greatly increases the workload of the user, and the manual feeding process is prone to uneven feeding, resulting in blockage of the feed bin and affecting the normal use of the extruder. A Chinese patent discloses a filler masterbatch dedicated to PE corrugated pipes and a preparation method thereof, with the publication number being CN109181046B. The filler masterbatch is composed of the following components in parts by mass: 30 to 50 parts of a carrier resin, 40 to 60 parts of an inorganic powder, 3 to 6 parts of a coupling agent, 2 to 5 parts of a lubricant, 2 to 5 parts of a dispersant, 4 to 8 parts of a toughening agent, and 1 to 3 parts of a black powder. The carrier resin is a mixture of high-density polyethylene and low-density polyethylene in any proportion, and the inorganic powder is a mixture of mica powder, talc powder and heavy calcium carbonate in a mass ratio of 1:1:1. The average particle size of the inorganic powder is 5.5 to 6.5 μm. The special filling masterbatch for PE corrugated pipes provided by the present invention can partially or completely replace PE resin for the production of PE corrugated pipes. The PE corrugated pipes prepared using the filling masterbatch provided by the present invention have the advantages of high ring stiffness, good impact performance, light weight, low material consumption, easy construction and installation, and good high and low temperature resistance. Through searching, the above is a case that is relatively close to the existing technology.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] Example 1: An embodiment of a device for preparing a masterbatch specifically for a highly filled PE film

[0037] See also Figure 1-8 A device for preparing a highly filled PE film masterbatch. The preparation method includes the following steps: first, the raw material particles to be processed into the highly filled PE film masterbatch are placed inside the storage box 301. By pulling the position of the partition plate 304, the size of the opening of the guide groove 303 is controlled, thereby controlling the amount of raw material particles falling. The raw material particles then flow from the guide groove 303 into the guide bin 302.

[0038] Step 2: After the raw material particles flow into the diversion bin 302, the conveyor belt 401 drives the conveyor box 403 to transport the raw material particles, and the raw material particles are transported to the top of the moving box 503, and then fall into the interior of the moving box 503;

[0039] Step 3: The motor 505 is started to drive the rotating block 506 to rotate. The rotating block 506 rotates and pulls the connecting rod 507 to rotate. The connecting rod 507 drives the connecting block 504 to perform reciprocating linear motion through the cooperation between the first rotating shaft and the second rotating shaft. When the moving box 503 is located at the top of the feeding hole 502, the raw material particles fall into the interior of the feeding bin 2 and are then extruded and formed by the extruder 1.

[0040] The extruder 1 includes an extruder 1 and a feed bin 2. The feed bin 2 is located at the top of the extruder 1. A storage mechanism 3 is provided on one side of the extruder 1.

By setting the storage mechanism 3, before using the extruder 1, the raw material particles for processing the special masterbatch of the highly filled PE film can be placed inside the storage box 301, and the position of the partition plate 304 can be pulled to control the size of the opening of the guide groove 303, thereby controlling the amount of raw material particles falling, thereby solving the problem that the extruder 1 does not have a material storage function;

[0042] The conveying mechanism 4 includes a conveyor belt 401, one end of which passes through the interior of the guide bin 302. A support leg 402 is fixedly connected to the bottom of the conveyor belt 401, and the number of the extended support legs 402 is two. A conveying box 403 is fixedly connected to the surface of the conveyor belt 401. By providing the conveying mechanism 4, after the raw material particles flow into the guide bin 302, the conveyor belt 401 can be used to drive the conveying box 403 to transport the raw material particles, and the raw material particles are transported to the top of the mobile box 503, and then fall into the interior of the mobile box 503. This solves the problem that the loading method is usually manual loading, which greatly increases the workload of the user.

[0043] The quantitative mechanism 5 includes a quantitative box 501, and a moving groove 14 is provided on the front side of the quantitative box 501. The moving groove 14 is used in conjunction with the connecting block 504. By setting the moving groove 14, a moving trajectory can be provided for the connecting block 504 and the moving box 503, so that they can only move back and forth in a straight line. The bottom of the quantitative box 501 is fixedly connected to the top of the feeding bin 2, and a feeding hole 502 for use with the feeding bin 2 is provided at the bottom of the quantitative box 501. A moving box 503 is provided inside the quantitative box 501, and a quantitative hole 15 is provided on the bottom of the inner wall of the moving box 503. There are three quantitative holes 15. By setting the quantitative holes 15, when the moving box 503 is located at the top of the feeding hole 502, the raw material particles can fall into the interior of the feeding bin 2 from the quantitative hole 15, thereby completing the quantitative feeding. The front side of the moving box 503 is fixedly connected to the connecting block 504, and one side of the connecting block 504 passes through the quantitative hole 503. On the outside of the measuring box 501, a motor 505 is fixedly connected to one side of the quantitative box 501, and the output end of the motor 505 is fixedly connected to the rotating block 506. The front side of the rotating block 506 is movably connected to the connecting rod 507 through the first rotating shaft. The end of the connecting rod 507 away from the rotating block 506 is movably connected to one side of the connecting block 504 through the second rotating shaft. By setting the quantitative mechanism 5, the motor 505 can be started to drive the rotating block 506 to rotate. While the rotating block 506 rotates, the connecting rod 507 is pulled to rotate. The connecting rod 507 drives the connecting block 504 to perform reciprocating linear operation through the cooperation between the first rotating shaft and the second rotating shaft. When the moving box 503 is located at the top of the feed hole 502, the raw material particles fall into the inside of the feed bin 2, thereby solving the problem that uneven feeding is easily caused during manual feeding, causing the feed bin 2 to be blocked, and affecting the normal use of the extruder 1.

[0044] Specifically, the front side of the storage box 301 is fixedly connected to the shell 6, and a push block 7 is provided inside the shell 6.

The bottom of the pin rod 8 passes through the bottom of the shell 6, and the top of the partition plate 304 is provided with a pin hole 9 for use with the pin rod 8.

[0045] Through the above technical solution, by setting the shell 6, the pushing block 7, the pin rod 8 and the pin hole 9, the pushing block 7 can be pushed upward so that the pushing block 7 drives the pin rod 8 to leave the inside of the pin hole 9, and then the position of the partition plate 304 can be adjusted to control the amount of raw material particles flowing into the diversion bin 302 from the storage box 301.

[0046] Specifically, there are a plurality of pin holes 9 , which are evenly distributed on the top of the partition plate 304 .

[0047] According to the above technical solution, by setting the pin hole 9, after the position of the partition plate 304 is adjusted, the position of the partition plate 304 can be quickly adjusted by inserting the pin rod 8 into the corresponding pin hole 9.

[0048] Specifically, the top of the pushing block 7 is fixedly connected to a spring 10 , and the top of the spring 10 is fixedly connected to the inner wall of the housing 6 .

[0049] Through the above technical solution, by setting the spring 10, the elastic force generated by the spring 10 can push the pushing block 7 and the pin rod 8 into the pin hole 9, thereby playing a resetting role.

[0050] Specifically, there are a plurality of conveying boxes 403 , which are evenly distributed on the outer surface of the conveying belt 401 .

[0051] Through the above technical solution, by providing the conveying box 403, the conveying box 403 can be driven by the conveyor belt 401 to transport the raw material particles, thereby solving the problem of manual loading and improving work efficiency.

[0052] Specifically, a positioning sleeve 11 is provided on the surface of the supporting leg 402 , and positioning blocks 12 are fixedly connected to both sides of the positioning sleeve 11 .

[0053] Through the above technical solution, by providing the positioning sleeve 11 and the positioning block 12 , the supporting leg 402 can be protected and the position of the supporting leg 402 can be limited.

[0054] Specifically, one side of the positioning block 12 is threadedly connected to a threaded rod 13 , and one side of the positioning block 12 is fixedly connected to one side of the extruder 1 through the threaded rod 13 .

[0055] According to the above technical solution, by providing the threaded rod 13 , the positions of the positioning block 12 and the positioning sleeve 11 can be fixed by the threaded rod 13 , thereby limiting the position of the supporting leg 402 .

[0056] Example 2 Example of a dedicated masterbatch for highly filled PE film

[0057] Specifically, the mass ratio of the PE film masterbatch is: calcium carbonate: 60, low-density polyethylene: 25, trioleyl isopropyl titanate: 1.3, thermoplastic elastomer: 10, titanium dioxide: 3, and antioxidant: 0.7.

[0058] Specifically, calcium carbonate, low-density polyethylene, trioleyl isopropyl titanate, thermoplastic elastomer, titanium dioxide and antioxidant are placed in a plastic mixer, the materials are swung by high-speed centrifugal force, and then extruded into shape. During the preparation, the temperature is set at 180°C-210°C, and the mixture is rotated at high temperature for 20-30 minutes.

[0059] Example 3 Example of a method for preparing a masterbatch for a highly filled PE film

[0060] Specifically, the preparation method comprises the following steps: first, placing raw material particles to be processed into a dedicated masterbatch for a highly filled PE film in a storage box (301), and controlling the size of the opening of the guide groove (303) by pulling the position of the partition plate (304), thereby controlling the amount of raw material particles falling, and then the raw material particles flow from the guide groove (303) into the guide bin (302);

[0061] Step 2: After the raw material particles flow into the guide bin (302), the raw material particles are transported by the conveyor belt (401) and driven by the conveyor box (403), and the raw material particles are transported to the top of the moving box (503), and then fall into the interior of the moving box (503);

[0062] Step 3: The motor (505) starts to drive the rotating block (506) to rotate. The rotating block 506 pulls the connecting rod (507) to rotate while rotating. The connecting rod (507) drives the connecting block (504) to perform reciprocating linear operation through cooperation with the first rotating shaft and the second rotating shaft. When the moving box (503) is located at the top of the feed hole (502), the raw material particles fall into the interior of the feed bin (2) and are then extruded and formed through the extruder (1).

[0063] Through the above technical solution, before using the extruder 1, the raw material particles that need to be processed into the special masterbatch of the highly filled PE film are first placed inside the storage box 301, and the pushing block 7 is pushed upward, so that the pushing block 7 drives the pin rod 8 to leave the pin hole 9. Then, the position of the partition plate 304 can be adjusted. By pulling the position of the partition plate 304 and then releasing the pushing block 7, the elastic force generated by the spring 10 pushes the pushing block 7 and the pin rod 8 into the pin hole 9, limiting the position of the partition plate 304, and controlling the size of the opening of the guide groove 303, thereby controlling the amount of raw material particles falling, thereby solving the problem that the extruder 1 does not have the function of storing materials. After that, the raw material particles flow into the guide bin 302 and are transported by the conveyor belt 401 to drive the conveyor box 4 03 transports the raw material particles, delivers the raw material particles to the top of the mobile box 503, and then falls into the interior of the mobile box 503, which solves the problem that the loading method is usually manual loading, which greatly increases the workload of the user. The motor 505 starts and drives the rotating block 506 to rotate. While the rotating block 506 rotates, it pulls the connecting rod 507 to rotate. The connecting rod 507 drives the connecting block 504 to perform reciprocating linear operation through the cooperation with the first rotating shaft and the second rotating shaft. When the mobile box 503 is located at the top of the feed hole, the raw material particles pass through the quantitative hole 15 and fall into the interior of the feed bin 2, thereby solving the problem that the manual loading process easily leads to uneven loading, causing the feed bin 2 to be blocked, and affecting the normal use of the extruder 1.

10. A method for preparing a highly filled PE film masterbatch preparation device, based on the highly filled PE film masterbatch preparation device according to any one of claims 1 to 7, characterized in that: Preparation method step 1: First, raw material particles to be processed into a dedicated masterbatch for a highly filled PE film are placed inside a storage box (301), and the size of the opening of the guide groove (303) is controlled by pulling the position of the partition plate (304), thereby controlling the amount of raw material particles falling, and then the raw material particles flow from the guide groove (303) into the guide bin (302); Step 2: After the raw material particles flow into the guide bin (302), the raw material particles are transported by the conveyor belt (401) and driven by the conveyor box (403), and the raw material particles are transported to the top of the moving box (503), and then fall into the interior of the moving box (503); Step 3: The motor (505) starts to drive the rotating block (506) to rotate. The rotating block 506 pulls the connecting rod (507) to rotate while rotating. The connecting rod (507) drives the connecting block (504) to perform reciprocating linear operation through cooperation with the first rotating shaft and the second rotating shaft. When the moving box (503) is located at the top of the feed hole (502), the raw material particles fall into the interior of the feed bin (2) and are then extruded and formed through the extruder (1).
