Description

Technical Field

[0001] This utility model relates to the field of plastic cutting technology, specifically to a modified plastic particle cutting device. Background Technology

[0002] The production process of modified plastics mainly involves mixing synthetic resins with modifiers and extruding the mixture through a twin-screw extruder, while implementing metered feeding to ensure quality. In this process, the extruder plays a crucial role, as it plasticizes the uniformly mixed material and extrudes it into the desired shape.

[0003] In the production of modified plastics, the choice of cutting method has a significant impact on the quality and performance of the product. Different cutting methods are suitable for different materials and product requirements.

[0004] Utility model application CN202223559332.2 discloses a cutting device for modified plastic strips, relating to the field of plastic processing technology. It solves the technical problems of current cutting devices where a large number of plastic strips are simultaneously fed into the cutting device, resulting in insufficient cutting and the cutting device being too close to the ground, making it difficult to remove the cut plastic granules and causing the plastic strips to accumulate at the bottom of the cutting device. The device includes a cutting box with a storage box on top. Four rectangular supports are fixedly connected between the cutting box and the storage box, and a sliding plate is slidably fitted between every two corresponding rectangular supports. This utility model allows the cut plastic granules to enter the top of a conveyor belt, enabling the plastic strips to be transported to the outside of the cutting box for collection, and allows for timed and quantitative feeding of the plastic strips, ensuring thorough cutting.

[0005] The aforementioned patent uses a quantitative dispensing of plastic strips to ensure thorough cutting. However, when cutting the plastic strips, their surface texture is too hard and their round shape makes it difficult for the cutting blade to cut them.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a modified plastic granule cutting device that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted:

[0009] A modified plastic pellet cutting device includes: a drying component, a cutting component, and a discharge component;

[0010] The cutting assembly consists of a mounting shell, a stirring shaft, a cutting blade, and a sieve plate; the mounting shell is rotatably connected to the stirring shaft, the stirring shaft is rotatably connected to the sieve plate, and the stirring shaft is fixedly connected to the cutting blade.

[0011] The cutting blades are provided in multiple sets and are arranged in an array around the stirring shaft.

[0012] Furthermore, the stirring shaft and the cutting blades on the stirring shaft are provided in two sets, and any one of the two sets of cutting blades is located in the middle position between the two adjacent sets of cutting blades of the other set of cutting blades.

[0013] Furthermore, the drying assembly includes a shell, a barrel, a feeding roller, a first gear, a second gear, and a blower; the shell is fixedly connected to the blower, the shell is fixedly connected to the barrel, the barrel is rotatably connected to the feeding roller, the feeding roller is fixedly connected to the first gear, the first gear meshes with the second gear, the second gear is provided in two sets, and the two sets of second gears are respectively fixedly connected to two sets of stirring shafts.

[0014] Furthermore, the diameter of the first gear is larger than the diameter of the second gear.

[0015] Furthermore, the discharge assembly consists of a rotating motor, a fixed housing, a rotating shaft, and a discharge roller; the fixed housing is fixedly connected to the outer housing, the fixed housing is rotatably connected to the rotating shaft, the rotating shaft is fixedly connected to the output shaft of the rotating motor, and the discharge roller is fixedly connected to the rotating shaft.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The modified plastic granule cutting device of the present invention heats the surface of the plastic strips during the feeding process, making the plastic strips softer and easier to cut. When the feeding roller rotates, the second gear is driven by the first gear to rotate. The rotation speed of the second gear is higher than that of the first gear, so that the rotation speed of the feeding roller for feeding is lower than that of the stirring shaft for cutting, which facilitates the cutting of the plastic strips. At the same time, the staggered cutting blades enable the plastic strips to be cut to the maximum extent, improving cutting efficiency and increasing cutting frequency. Attached Figure Description

[0026] like Figures 1 to 5 As shown, a modified plastic granule cutting device includes: a drying component 1, a cutting component 2, and a discharge component 3.

[0027] The drying assembly 1 includes a shell 11, a barrel 12, a feeding roller 13, a first gear 14, a second gear 15, and a blower 16. The shell 11 is fixedly connected to the blower 16 and the barrel 12. The barrel 12 is rotatably connected to the feeding roller 13. The feeding roller 13 is fixedly connected to the first gear 14. The first gear 14 meshes with the second gear 15. There are two sets of the second gear 15, and each set of the second gear 15 is fixedly connected to two sets of stirring shafts 22. The blower 16 blows air onto the surface of the plastic strip. At the same time, a heater is provided on the side of the blower 16, which raises the surface temperature of the plastic strip. Meanwhile, the surface of the barrel 12 is opened... Multiple sets of holes allow for better heat transfer to the interior of the barrel 12. Plastic strips are placed inside the outer shell 11, and the surface of these strips is heated during feeding, softening them and making them easier to cut. Simultaneously, a motor at the top of the feeding roller 13 drives its rotation to feed the plastic strips. This is existing technology and will not be elaborated further. Because the feeding roller 13 is spiral-shaped, the plastic strips fall off layer by layer as it rotates, increasing the heating time and softening the strips. The rotation of the feeding roller 13 also drives the first gear 14, and the second gear 15 rotates along with it, facilitating the cutting blade 23's cutting of the plastic strips.

[0028] The cutting assembly 2 consists of a mounting shell 21, a stirring shaft 22, a cutting blade 23, and a sieve plate 24. The mounting shell 21 is rotatably connected to the stirring shaft 22, the stirring shaft 22 is rotatably connected to the sieve plate 24, and the stirring shaft 22 is fixedly connected to the cutting blade 23. After the plastic strip is heated and softened, it falls into the mounting shell 21. When the feeding roller 13 rotates, it drives the second gear 15 to rotate through the first gear 14, causing the two sets of stirring shafts 22 to rotate. The stirring shaft 22 drives the cutting blade 23 to rotate, cutting the plastic strip. The cut plastic strip falls to the top of the sieve plate 24. Plastic strips of the appropriate size pass through the sieve plate 24 and enter the discharge assembly 3 for discharge.

[0029] As a supplement: the cutting blades 23 are provided in multiple sets and are arranged in an array around the stirring shaft 22. The stirring shaft 22 and the cutting blades 23 on the stirring shaft 22 are provided in two sets, and any one of the two sets of cutting blades 23 is located in the middle of the two adjacent sets of cutting blades 23 of the other set. The diameter of the first gear 14 is larger than the diameter of the second gear 15. When the feeding roller 13 rotates, the second gear 15 is driven to rotate by the first gear 14. The rotation speed of the second gear 15 is higher than that of the first gear 14, so that the rotation speed of the feeding roller 13 for feeding is lower than the rotation speed of the stirring shaft 22 for cutting, which facilitates the cutting of plastic strips. At the same time, the staggered arrangement of the cutting blades 23 allows the plastic strips to be cut to the maximum extent, improving cutting efficiency and increasing cutting frequency.

[0030] The discharge assembly 3 consists of a rotating motor 31, a fixed housing 32, a rotating shaft 33, and a discharge roller 34. The fixed housing 32 is fixedly connected to the outer housing 11, and the fixed housing 32 is rotatably connected to the rotating shaft 33. The rotating shaft 33 is fixedly connected to the output shaft of the rotating motor 31, and the discharge roller 34 is fixedly connected to the rotating shaft 33. The rotating motor 31 drives the rotating shaft 33 to rotate, causing the plastic strips passing through the sieve plate 24 to fall into the fixed housing 32. The rotating discharge roller 34 feeds the cut plastic strips, facilitating the output of the plastic strips.

[0031] Working principle:

[0032] Air is blown onto the surface of the barrel 12 by the blower 16, and a heater is provided on the side of the blower 16 to raise the surface temperature of the barrel 12. Multiple sets of holes are made on the surface of the barrel 12 to better transfer heat to the interior. Plastic strips are placed inside the outer shell 11. During the feeding process, the surface of the plastic strips is heated, softening them and making them easier to cut. After softening, the plastic strips fall into the mounting shell 21. When the feeding roller 13 rotates, it drives the second gear 15 through the first gear 14, causing the two sets of stirring shafts 22 to rotate. The stirring shaft 22 rotates, driving the cutting blade 23 to rotate and cut the plastic strips. When the feeding roller 13 rotates, the first gear 14 drives the second gear 15 to rotate. The speed of the second gear 15 is higher than that of the first gear 14, so that the speed of the feeding roller 13 is lower than that of the stirring shaft 22, which facilitates the cutting of the plastic strips. The rotating motor 31 drives the rotating shaft 33 to rotate, so that the plastic strips passing through the screen plate 24 fall into the fixed shell 32. The rotating discharge roller 34 feeds the cut plastic strips, which facilitates the output of the plastic strips.
