Description

Technical Field

[0001] This utility model belongs to the field of plastic processing technology, specifically relating to a plastic particle mixing device with a dispersing structure. Background Technology

[0002] Plastic granules, also known as plastic particles or plastic pellets, refer to solid granular raw materials with fixed shapes and uniform sizes, which are made from high molecular polymers through specific processes. They are high molecular resins obtained from crude oil refining in the plastics industry chain. Through molding processes such as injection molding, extrusion, and blow molding, they are processed into various plastic products and are the most basic and core raw material form in the plastics manufacturing industry.

[0003] A search revealed that Chinese patent CN215703093U discloses a "plastic granule mixing device," comprising a frame, a controller, and a mixing device. The controller is mounted on the right side of the frame, and the mixing device is installed inside the bottom of the frame. The plastic granule mixing device further includes a screening component mounted on the front surface of the frame and a power unit mounted on the bottom of the screening component. This plastic granule mixing device, through the combined use of a reducer, support rod, mixing rod, and a first motor, provides power for mixing plastic granules. Through the combined use of a shell, sliding plate, box, filter screen, and vertical plate, it enables the screening of the mixed plastic granules. Through the combined use of a motor frame, a second motor, a disc, a support plate, a slider, and a support rod, it provides power for the screening component, enabling the sorting of the mixed plastic granules by size.

[0004] However, the following defects still exist: (1) The particles are turned over by a single stirring rod without a special preliminary dispersing component. When the plastic particles clump together due to moisture, the stirring rod cannot effectively break up the agglomerated structure, causing the clumped particles to enter the subsequent process with the stirring process. These undispersed clumped particles are prone to causing mold blockage during injection molding and extrusion, affecting production efficiency. (2) The stirring dimension is singular, the particle mixing uniformity is poor, and the stirring components are mostly designed with fixed trajectory, which can only unidirectionally or locally tumble the particles, and cannot achieve multi-dimensional full mixing. For different plastic particles, there will be problems of local accumulation and uneven mixing.

[0005] Therefore, a plastic particle mixing device with a dispersing structure is proposed. Utility Model Content

[0006] The purpose of this utility model is to address the existing problems.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a plastic granule mixing device with a dispersing structure, comprising a device body, a docking plate fixedly connected to the side surface of the device body, a controller fixedly connected to the upper surface of the docking plate, a support rod fixedly connected to one side of the device body, and a separation processing shell installed on the upper surface of the support rod.

[0008] A protective shell is fixedly connected to the upper surface of the separation processing shell, a connecting block is fixedly connected to the inner ring surface of the protective shell, a motor is fixedly connected to one side of the connecting block, a mixing plate is fixedly sleeved at the top of the output shaft of the motor, and a first mixing rod is fixedly connected to the bottom surface of the mixing plate.

[0009] A second mixing rod is fixedly connected to the bottom surface of the mixing plate, an installation rod is fixedly connected to the upper surface of the separation processing shell, a return spring is fixedly connected to the upper surface of the separation processing shell, and a guide shell is fixedly connected to the upper surface of the separation processing shell.

[0010] As a preferred technical solution of this utility model, the upper surface of the protective shell is provided with heat dissipation openings, and there are multiple heat dissipation openings. The multiple heat dissipation openings can quickly dissipate the heat generated by the motor during operation to the outside of the protective shell, and prevent the motor from experiencing performance degradation or failure due to long-term exposure to high temperature environment.

[0011] As a preferred technical solution of this utility model, the motor is connected to the protective shell through a connecting block, and the connecting block is symmetrically arranged with the vertical center line of the motor as the axis of symmetry. The symmetrical connecting block can provide balanced support for the motor, avoid the motor from shaking or deviating due to uneven force when running at high speed, and reduce the wear of the connection between the motor output shaft and the mixing plate.

[0012] As a preferred technical solution of this utility model, the bottom surface of the main body of the device is fitted with anti-slip fixing feet, and there are multiple anti-slip fixing feet that are parallel to each other. The multiple parallel anti-slip fixing feet can increase the contact area between the main body of the device and the ground, and enhance the friction with the ground through anti-slip material, so as to prevent the device from shifting or sliding when stirring plastic particles.

[0013] As a preferred technical solution of this utility model, the separation processing shell is connected by a support rod and a docking plate, and there are multiple support rods that are parallel to each other. The multiple parallel support rods can evenly distribute the weight of the separation processing shell and avoid excessive force on a single support rod, which may cause it to bend or break.

[0014] As a preferred technical solution of this utility model, a dispersing plate is fixedly connected to the upper surface of the mounting rod, and the dispersing plate is connected to the separation processing shell through the mounting rod. The dispersing plate can initially disperse the plastic particles that may clump together when the plastic particles enter the separation processing shell through the guide shell. Combined with the secondary stirring of the first mixing rod and the second mixing rod driven by the mixing plate, the plastic particles are fully dispersed, and the clumped particles are prevented from affecting the uniformity of the raw materials in subsequent processing.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a separation processing shell, and a dispersing plate fixed on the separation processing shell by a mounting rod, the plastic granules can be initially dispersed when they enter the shell after being damp and agglomerated or after adding color masterbatch. This breaks up the agglomerated structure of the granules. The motor drives the mixing plate and the first and second mixing rods at the bottom to rotate at high speed, which deeply stirs the initially dispersed granules. This ensures that different types and batches of plastic granules are fully mixed. This avoids agglomerated granules from entering the subsequent injection molding and extrusion processes, ensures the uniformity of raw materials, and reduces finished product defects caused by uneven raw materials.

[0016] 2. The separation processing shell, connected to the docking plate by multiple parallel support rods, evenly distributes the weight of the particles and stirring components within the shell, preventing the breakage of a single support rod under stress. Multiple parallel anti-slip fixing feet at the bottom of the main body increase friction to prevent displacement of the device during stirring and vibration, while ensuring the main body is level and preventing particle accumulation due to device tilt. Multiple heat dissipation openings on the protective shell can quickly dissipate the heat generated by the motor, preventing high-temperature motor attenuation. Furthermore, the motor is fixed by symmetrically arranged connecting blocks to prevent wobbling and deviation during high-speed operation, reducing wear on the output shaft and mixing plate.

[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] Please see Figure 1-5 The present invention provides a technical solution: a plastic particle mixing device with a dispersing structure, comprising a device body 1, a docking plate 3 fixedly connected to the side surface of the device body 1, a controller 2 fixedly connected to the upper surface of the docking plate 3, a support rod 4 fixedly connected to one side of the device body 1, a separation processing shell 5 installed on the upper surface of the support rod 4, and a protective shell 7 fixedly connected to the upper surface of the separation processing shell 5.

[0021] In this embodiment, the upper surface of the protective shell 7 is provided with heat dissipation openings 10, and there are multiple heat dissipation openings 10. The multiple heat dissipation openings 10 can quickly dissipate the heat generated by the motor 9 during operation to the outside of the protective shell 7, so as to prevent the motor 9 from experiencing performance degradation or failure due to long-term exposure to high temperature environment. The motor 9 is connected to the protective shell 7 through connecting blocks 8, and the connecting blocks 8 are symmetrically arranged with the vertical center line of the motor 9 as the axis of symmetry. The symmetrical connecting blocks 8 can provide balanced support for the motor 9, so as to prevent the motor 9 from shaking or deviating due to uneven force when running at high speed, and reduce the wear of the connection between the output shaft of the motor 9 and the mixing plate 11.

[0022] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a connecting block 8 is fixedly connected to the inner ring surface of the protective shell 7, a motor 9 is fixedly connected to one side of the connecting block 8, and a mixing plate 11 is fixedly sleeved on the top of the output shaft of the motor 9.

[0023] In this embodiment, the bottom surface of the device body 1 is fitted with anti-slip fixing feet 17, and there are multiple anti-slip fixing feet 17 that are parallel to each other. The multiple parallel anti-slip fixing feet 17 can increase the contact area between the device body 1 and the ground, and enhance the friction with the ground through the anti-slip material, so as to prevent the device from shifting or sliding when stirring plastic particles. The separation processing shell 5 is connected to the docking plate 3 through the support rod 4, and there are multiple support rods 4 that are parallel to each other. The multiple parallel support rods 4 can evenly distribute the weight of the separation processing shell 5, and prevent a single support rod 4 from being bent or broken due to excessive force.

[0024] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a first mixing rod 12 is fixedly connected to the bottom surface of the mixing plate 11, a second mixing rod 16 is fixedly connected to the bottom surface of the mixing plate 11, an installation rod 13 is fixedly connected to the upper surface of the separation processing shell 5, a return spring 14 is fixedly connected to the upper surface of the separation processing shell 5, and a guide shell 6 is fixedly connected to the upper surface of the separation processing shell 5.

[0025] In this embodiment, a dispersing plate 15 is fixedly connected to the upper surface of the mounting rod 13, and the dispersing plate 15 is connected to the separation processing shell 5 through the mounting rod 13. The dispersing plate 15 can initially disperse the plastic particles that may clump together when the plastic particles enter the separation processing shell 5 through the guide shell 6. With the secondary stirring of the first mixing rod 12 and the second mixing rod 16 driven by the mixing plate 11, the plastic particles are fully dispersed, and the clumped particles are prevented from affecting the uniformity of the raw materials in subsequent processing.

[0026] Working principle: When the user operates the device, the multiple parallel anti-slip fixed feet 17 attached to the bottom surface of the main body 1 are in stable contact with the ground. The anti-slip material increases the friction with the ground to prevent displacement during operation and ensures that the main body 1 is level, avoiding particle accumulation during subsequent mixing. The controller 2 fixed on the upper surface of the docking plate 3 is operated to set parameters according to the type of plastic particles and mixing requirements. Then, the controller 2 sends a start command to trigger the motor 9 to start running. The plastic particles to be mixed are poured into the guide shell 6 fixed on the upper surface of the separation processing shell 5. The guide shell 6 guides the particles smoothly into the interior of the separation processing shell 5, avoiding particle splashing or accumulation at the shell opening. During the falling process, the particles will first come into contact with the dispersing plate 15 fixed on the separation processing shell 5 by the mounting rod 13. The dispersing plate 15 physically impacts and separates the clumped particles, breaking the agglomerated structure and achieving initial dispersal, laying the foundation for subsequent deep mixing. Meanwhile, the reset spring 14 fixed on the upper surface of the separation processing shell 5 can buffer the vibration generated when the particles hit the dispersing plate 15, and avoid damage to the connection between the mounting rod 13 and the separation processing shell 5. When the motor 9 is running, its output shaft drives the mixing plate 11 fixed at the top to rotate at high speed. When the mixing plate 11 rotates, the first mixing rod 12 and the second mixing rod 16 fixed on its bottom surface rotate synchronously to stir the plastic particles after initial dispersal in multiple dimensions. The first mixing rod 12 and the second mixing rod 16 can turn the particles from different angles to ensure that different types and batches of particles are fully mixed and to avoid uneven local mixing. The heat generated during the operation of the motor 9; Multiple heat dissipation openings 10 on the upper surface of the protective shell 7 allow for rapid discharge, preventing performance degradation of the motor 9 due to high temperatures, ensuring stable stirring speed, and guaranteeing stirring effect. Based on the time or speed parameters set by the controller 2, when the stirring reaches the preset requirements, the controller 2 automatically sends a stop command, the motor 9 stops running, and the first mixing rod 12, the second mixing rod 16, and the mixing plate 11 stop rotating. The discharge structure of the separation processing shell 5 is opened, and the uniformly stirred plastic granules are removed. Subsequently, the condition of each component is checked, such as whether the anti-slip fixing feet 17 are still stable, whether the heat dissipation openings 10 are blocked, and whether the dispersing plate 15 is worn, ensuring that the device is in normal condition before the next use. Throughout the entire process, the separation processing shell 5 is connected to the docking plate 3 through multiple parallel support rods 4. The support rods 4 evenly distribute the weight of the separation processing shell 5, the internal granules, and the stirring components, preventing a single support rod 4 from breaking under stress, ensuring that the separation processing shell 5 always remains horizontal, providing a stable structural foundation for the uniform dispersal and stirring of the granules.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
