[0002] The plastic master batch processing equipment capable of controlling particle size usually refers to a plastic granulator, which can process plastic raw materials into particles of a specific particle size for subsequent plastic processing and production, and is equipped with a cooling pool for cooling extruded melt strips and a rotary cutter for cutting the melt strips into particles, but the cooling water in the cooling pool needs to be frequently replaced during use to ensure the cooling effect, resulting in the need for intermittent shutdown and affecting the processing efficiency.

[0003] To solve the above problems, the utility model file provides a plastic master batch processing equipment capable of controlling particle size. UTILITY MODEL CONTENT

[0004] The utility model provides a plastic master batch processing equipment capable of controlling particle size, which solves the problem of frequent replacement of cooling water in the cooling pool during use to ensure the cooling effect, resulting in the need for intermittent shutdown and affecting the processing efficiency in the prior art.

[0005] The utility model provides the following technical scheme:

[0006] A plastic master batch processing equipment capable of controlling particle size comprises:

[0007] A plastic granulator body is provided with a cooling pool for cooling extruded melt strips at the extrusion port of the plastic granulator body, another end of the cooling pool is fixedly provided with a rotary cutter for cutting the cooled melt strips into particles, and the bottom of the rotary cutter is fixedly provided with a receiving hopper.

[0008] A uniform feeding assembly is arranged in the feeding hopper at the top of the plastic granulator body to uniformly extrude and deliver raw materials to the plastic granulator body, avoiding accumulation of the raw materials.

[0009] A water circulation assembly is arranged above the cooling pool to cool the cooling water in the cooling pool, avoiding frequent replacement of the cooling water.

[0010] In one possible design, the uniform feeding assembly comprises two extrusion rollers rotatably mounted on the inner wall of the feeding hopper, one end of each extrusion roller penetrates through the outer wall of the feeding hopper and is fixedly provided with a corresponding gear, the two gears are meshed with each other, and the outer wall of the feeding hopper is fixedly mounted with a driving motor for driving one of the extrusion rollers to rotate.

[0011] In one possible design, the water circulation component includes a rotating plate fixedly mounted on the outer wall of the cooling pool, a water pump fixedly mounted on the top of the rotating plate, the input end of the water pump is connected to a water pumping pipe, the other end of the water pumping pipe extends into the end of the cooling pool, and the output end of the water pump is connected to the starting end of the cooling pool through a water supply pipe.

[0012] In one possible design, multiple cooling fans are fixedly installed on the outer walls of the water suction pipe and the water delivery pipe, a connecting rod is fixedly installed at the center of the rotating shaft of the cooling fan, the other end of the connecting rod passes through the inner wall of the corresponding tube body and is fixedly installed with an impeller, and the connecting rod is rotatably connected to the corresponding tube body.

[0013] In one possible design, a sealing piece is threadedly connected to the extrusion port of the plastic granulator body, and the sealing piece is provided with multiple extrusion holes for limiting the radius of the melting rod. Two handles are symmetrically fixed on the sealing piece for easy replacement of the sealing piece.

[0014] In a possible design, a plurality of guide rollers for supporting the extruded molten rods are equidistantly mounted on the inner wall of the cooling pool.

[0015] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0016] In the present application, when used specifically, the operator first adds the plastic raw material into the feeding hopper on the top of the plastic granulator body, selects a suitable sealing sheet according to the required plastic masterbatch particle size and installs it on the extrusion port of the plastic granulator body, and then starts the drive motor, which drives one of the extrusion rollers to rotate. Through the engagement of the two gears, the two extrusion rollers rotate synchronously relative to each other. The rotation of the extrusion rollers uniformly squeezes the plastic raw material in the feeding hopper and transports it into the plastic granulator body, ensuring that the raw material will not accumulate during the transportation process;

[0017] The plastic raw materials undergo heating and plasticizing processes in the plastic granulator body, and are finally extruded from the extrusion port to form molten bars. When the molten bars pass through the extrusion hole of the sealing plate, their radius is limited to form molten bars of predetermined size. The molten bars enter the cooling pool and are initially cooled by cooling water. During the cooling process, the molten bars are supported by multiple guide rollers to ensure stable movement. The cooled molten bars are cut by a rotary cutter and cut into plastic masterbatches of predetermined length. The cut plastic masterbatches fall into the receiving hopper for easy collection.

[0018] At the same time, the water pump starts and draws the heated cooling water from the end of the cooling pool. When the cooling water passes through the pumping pipe, the water flow drives the impeller to rotate, and then drives the cooling fan to rotate through the connecting rod, which initially cools the cooling water in the pumping pipe. The cooled cooling water returns to the starting end of the cooling pool through the water supply pipe to form a cycle. The cooling water is also cooled by the cooling fan in the water supply pipe to ensure that the temperature of the circulating cooling water is always maintained at a low level.

[0019] The utility model has the following beneficial effects:

[0020] Uniform conveying of raw materials: The design of the uniform feeding component ensures the uniformity of raw materials during the conveying process, avoiding the impact of raw material accumulation on equipment operation;

[0021] Energy saving and environmental protection: The design of the water circulation component enables the cooling water to be recycled, reducing the consumption and waste of cooling water, while also reducing the operating costs of the equipment. In addition, the design of the cooling fan further improves the cooling efficiency and reduces energy consumption;

[0022] The utility model has the advantages of simple structure, convenient operation, energy saving and environmental protection, and can meet the processing needs of plastic masterbatches with different particle size requirements. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described 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.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "middle", "length", "inner" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0030] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0031] Example 1

[0032] Please refer to Figure 1-4 , a plastic masterbatch processing equipment with controllable particle size, which is used in the field of plastic masterbatch production equipment, including:

[0033] The plastic granulator body 1 is the core part of the entire equipment, model SJSL-51, which is used to heat, melt and extrude the plastic raw materials. A cooling pool 2 is provided at the extrusion port of the plastic granulator body 1. The cooling pool 2 is used to receive the high-temperature molten bars extruded from the extrusion port and cool them. A rotary cutter 3 is fixedly provided on the top of the other end of the cooling pool 2. After the molten bars are cooled by the cooling pool 2, the rotary cutter 3 cuts them into granules. A receiving hopper 4 is fixedly provided at the bottom of the cutter 3 for collecting the cut plastic masterbatch.

[0034] A uniform feeding assembly is provided in the feeding hopper 5 at the top of the plastic granulator body 1. The assembly includes two squeezing rollers 6 rotatably mounted on the inner wall of the feeding hopper 5. One end of the two squeezing rollers 6 passes through the outer wall of the feeding hopper 5, and mutually meshing gears 7 are fixed on the outer wall. A driving motor 8 is fixedly mounted on the outer wall of the feeding hopper 5 for driving one of the squeezing rollers 6 to rotate, thereby driving the other squeezing roller 6 to rotate synchronously through the meshing of the gears 7. This design allows the raw materials to be uniformly squeezed in the feeding hopper 5, thereby preventing the raw materials from accumulating during the transportation process and ensuring the stable operation of the plastic granulator body 1.

[0035] The water circulation component is located above the cooling pool 2 and is used to cool the cooling water in the cooling pool 2. The component includes a mounting plate 12 mounted on the outer wall of the cooling pool 2. A water pump 13 is fixedly mounted on the top of the mounting plate 12. The input end of the water pump 13 is connected to a water pumping pipe 14. The other end of the water pumping pipe 14 extends into the end of the cooling pool 2 to extract the heated cooling water. The output end of the water pump 13 is connected to the starting end of the cooling pool 2 through a water pipe 15, forming a water cycle. This design allows the cooling water to be recycled and avoids the trouble of frequent replacement of cooling water.

[0036] In order to further improve the cooling effect, a plurality of cooling fans 16 are fixedly provided on the outer walls of the water suction pipe 14 and the water delivery pipe 15. A connecting rod 17 is fixedly provided at the center of the rotating shaft of the cooling fan 16. The other end of the connecting rod 17 passes through the inner wall of the corresponding pipe body and is fixedly provided with an impeller 18. The connecting rod 17 is rotatably connected to the corresponding pipe body. When water flows through the water suction pipe 14 or the water delivery pipe 15, it will drive the impeller 18 to rotate, and then drive the cooling fan 16 to rotate through the connecting rod 17 to cool the water flow in the pipe. This design utilizes the power of the water flow itself and can achieve a cooling effect without additional energy.

[0037] Example 2

[0038] Improvements based on Example 1:

[0039] Please refer to Figure 3 In order to facilitate the control of the particle size of the plastic masterbatch, a sealing piece 9 is threadedly connected to the extrusion port of the plastic granulator body 1. The sealing piece 9 is provided with a plurality of extrusion holes for limiting the radius of the melting bar. Different extrusion holes can be selected as needed to adjust the radius of the melting bar. Two handles 10 are symmetrically fixed on the sealing piece 9 to facilitate the operator to replace the sealing piece 9.

[0040] Please refer to Figure 1 A plurality of guide rollers 11 are installed on the inner wall of the cooling pool 2 at equal intervals to support the molten bar extruded from the extrusion port so that it can smoothly enter the cooling pool 2 for cooling. The rotation design of the guide rollers 11 can reduce the friction between the molten bar and the inner wall of the cooling pool 2 and extend the service life of the equipment.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of the plastic granulator body 1, the rotary cutter 3, the drive motor 8 and the water pump 13 are commonplace, and are all conventional means or common knowledge, and will not be elaborated here.
