Description

Dispersing and grinding apparatus for processing plastic additives Technical Field

[0001] This utility model mainly relates to the technical field of plastic additive processing, specifically to a dispersion and grinding device for plastic additive processing. Background Technology

[0002] Plastic additives, also known as plastic auxiliaries, are a class of auxiliary materials used to improve the properties of plastics. They play an important role in the processing and use of plastics, endowing them with various specific properties to meet the needs of different application scenarios.

[0003] In existing plastic additive processing technologies, traditional dispersion and grinding devices often have some shortcomings. First, when encountering larger particles, these particles may spin idly with the rotation of the grinding rollers, failing to receive sufficient grinding force, resulting in incomplete grinding. Second, the plastic additives may not be sufficiently and evenly dispersed before grinding, leading to uneven material distribution during the grinding process. Summary of the Invention

[0004] This utility model mainly provides a dispersion and grinding device for processing plastic additives, in order to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A dispersing and grinding device for processing plastic additives includes a base plate and a dispersing box. Fixed plates are fixedly connected to both sides of the top of the base plate, and a grinding box is connected between the two fixed plates. A first grinding component is provided on one side of the inside of the grinding box, and a second grinding component is provided on one side of the first grinding component inside the grinding box.

[0007] A first motor is fixedly installed on the top of the dispersion box, and the output shaft of the first motor passes through the interior of the dispersion box to provide a dispersion mechanism.

[0008] Preferably, a solenoid valve is fixedly connected to the top of the grinding box, and the top of the solenoid valve is connected to the bottom of the dispersion box.

[0009] Preferably, the first grinding assembly includes a first grinding roller and a second motor. The first grinding roller is connected to one side of the inside of the grinding box via a rotating shaft, and one end of the first grinding roller passes through one side of the grinding box and is connected to the second motor. The second motor is fixedly installed on one side of the grinding box.

[0010] Preferably, the second grinding assembly includes a second grinding roller and a third motor. The second grinding roller is connected to one side of the first grinding assembly via a rotating shaft inside the grinding box, and one end of the second grinding roller passes through one side of the grinding box and is connected to the third motor. The third motor is fixedly installed on one side of the grinding box.

[0011] Preferably, multiple pulverizing blades are provided on the outer side of one end of the first grinding roller and the outer side of one end of the second grinding roller.

[0012] Preferably, the dispersing mechanism includes a rotating rod and dispersing blades, the output shaft of the first motor is inserted into the dispersing box and connected to the rotating rod, and multiple dispersing blades are connected to the outside of the rotating rod.

[0013] Preferably, the outer top of the rotating rod is connected to two sets of connecting rods, and one end of each set of connecting rods is connected to a limiting wheel through a rotating shaft, and the limiting wheel rolls and rubs against the inside of the dispersion box.

[0014] Preferably, the grinding box has a discharge port at the bottom and the dispersion box has a feed port on the top side of the first motor.

[0015] Preferably, the top of the base plate is fixedly connected to a support rod on one side of each of the two fixed plates, and one end of each of the two support rods is fixedly connected to a distributed box.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By using the first and second grinding components, and by setting crushing blades on the surfaces of the first and second grinding rollers, it is possible to effectively handle plastic additives of different particle sizes. When the plastic additives fall from the dispersion box into the grinding box, the second and third motors drive the first grinding roller to rotate clockwise and the second grinding roller to rotate counterclockwise, respectively, forming relative motion to grind the material. For larger plastic additive blocks, the crushing blades can crush them in time, avoiding large particles from spinning idly under the drive of the grinding rollers without receiving grinding force, thus ensuring that all materials are fully ground, further improving the uniformity and fineness of grinding. This not only improves grinding efficiency but also avoids the problem of incomplete grinding caused by uneven particle size, meeting the high requirements of fineness and consistency in plastic additive processing.

[0018] The dispersion mechanism inside the dispersion box achieves efficient and uniform dispersion of plastic additives. After the operator puts the plastic additives into the dispersion box through the feed inlet, the first motor drives the rotating rod and dispersion blades to rotate. The shearing force of the dispersion blades makes the plastic additives reach a uniform dispersion state before entering the grinding box. This avoids the problem of insufficient grinding or local overload caused by uneven distribution of materials during the grinding process, and significantly improves grinding efficiency and quality.

[0026] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings, which illustrate several embodiments of the utility model. However, this utility model can be implemented in different forms and is not limited to the embodiments described in the text. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and comprehensive. Embodiments

[0027] Please refer carefully to Figures 1-5. The dispersing and grinding device for processing plastic additives includes a base plate 1 and a dispersing chamber 2. Fixed plates 3 are fixedly connected to both sides of the top of the base plate 1. Support rods 15 are fixedly connected to one side of each of the two fixed plates 3, and one end of each support rod 15 is fixedly connected to the dispersing chamber 2, thus firmly supporting the dispersing chamber 2 above the base plate 1 and ensuring its stability during operation. A grinding chamber 4 is connected between the two fixed plates 3. A discharge port 13 is provided at the bottom of the grinding chamber 4 for discharging the ground plastic additives. A solenoid valve 9 is fixedly connected to the top of the grinding chamber 4, and the top of the solenoid valve 9 is connected to the bottom of the dispersing chamber 2. Through the control of the solenoid valve 9, the material in the dispersing chamber 2 can be dispersed according to a predetermined... The flow rate and time are controlled to enter the grinding chamber 4, thereby ensuring the uniformity and stability of the grinding process. A first grinding assembly 5 is located on one side inside the grinding chamber 4. The first grinding assembly 5 includes a first grinding roller 501 and a second motor 502. The first grinding roller 501 is connected to one side of the grinding chamber 4 via a rotating shaft, and one end of the first grinding roller 501 passes through one side of the grinding chamber 4 and is connected to the second motor 502. The second motor 502 is fixedly installed on one side of the grinding chamber 4. A second grinding assembly 6 is located inside the grinding chamber 4 on one side of the first grinding assembly 5. The second grinding assembly 6 includes a second grinding roller 601 and a third motor 602. The second grinding roller 601 is connected to one side of the first grinding assembly 5 inside the grinding chamber 4 via a rotating shaft. A third motor 602 is connected to one side of the grinding box 4, passing through it. The third motor 602 is fixedly installed on one side of the grinding box 4. It drives the second motor 502 to rotate the first grinding roller 501 clockwise and the third motor 602 to rotate the second grinding roller 601 counterclockwise. This causes the plastic additive blocks to be crushed and ground together when they fall into the gap between the first and second grinding rollers 501 and 601. Multiple pulverizing blades 10 are provided on the outer side of one end of both the first and second grinding rollers 501 and 601. These blades can crush larger plastic additive blocks, preventing them from rotating with the first and second grinding rollers 501 and thus not being subjected to the crushing force and unable to be ground. A first motor 7 is fixedly installed on the top of the dispersion box 2. A feed inlet 14 is opened on one side of the first motor 7 on the top of the dispersion box 2. A dispersion mechanism 8 is installed inside the dispersion box 2 through the output shaft of the first motor 7. The dispersion mechanism 8 includes a rotating rod 801 and dispersion blades 802. After the output shaft of the first motor 7 enters the dispersion box 2, it is connected to the rotating rod 801. Multiple dispersion blades 802 are connected to the outer side of the rotating rod 801. When the first motor 7 starts, it drives the rotating rod 801 to rotate, causing the dispersion blades 802 to rotate at high speed inside the dispersion box 2. This fully stirs and disperses the plastic additives entering the dispersion box 2, ensuring that the material reaches a relatively uniform state before entering the grinding box 4, creating favorable conditions for the subsequent grinding process.Two sets of connecting rods 11 are connected to the outer top of the rotating rod 801. One end of each set of connecting rods 11 is connected to a limiting wheel 12 via a rotating shaft. The limiting wheel 12 rolls and rubs against the inner wall of the dispersion box 2, thereby limiting the rotation of the rotating rod 801.

[0028] The specific operation method of this utility model is as follows:

[0029] During use, the operator can feed the plastic additive into the dispersion box 2 through the feed port 14 and drive the first motor 7, so that its output shaft drives the rotating rod 801 to rotate, thereby causing the rotating rod 801 to drive the dispersing blade 802 to rotate. The shearing force of the dispersing blade 802 makes the plastic additive evenly dispersed, which is convenient for subsequent grinding. After dispersion, the solenoid valve 9 is opened to let the plastic additive fall into the grinding box 4. The second motor 502 is started, so that its output shaft drives the first grinding roller 501 to rotate clockwise. The third motor 602 is started, so that its output shaft drives the second grinding roller 601 to rotate counterclockwise, thereby grinding the plastic additive. When encountering large pieces of plastic additive, the crushing blades 10 located on the surface of the first grinding roller 501 and the second grinding roller 601 can crush the plastic additive pieces. This prevents some large pieces of plastic additive from rotating with the first grinding roller 501 and the second grinding roller 601 without being subjected to mutual squeezing force and thus unable to be ground. After grinding is completed, the material is discharged through the discharge port 13.

[0030] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
