Description

Technical Field

[0001] This utility model relates to the field of impurity removal from plastic track granules, and more specifically, it relates to an impurity removal device for the preparation of plastic track granules. Background Technology

[0002] With the increasing awareness of fitness among the public and the vigorous development of sports, synthetic running tracks, as a high-quality sports field paving material, have been widely used in various schools, stadiums, and other venues. Synthetic running tracks possess excellent elasticity, slip resistance, wear resistance, and weather resistance, providing athletes with a comfortable and safe sports environment. In the preparation process of synthetic running track granules, the quality of the raw materials directly affects the performance and quality of the final product. However, whether it is recycled waste plastic or newly purchased basic plastic raw materials, they often contain various impurities. These impurities may include metal shavings, small stones, wood chips, textile fibers, and fragments of other plastic products.

[0003] Conventional impurity removal methods may not allow particles to fully contact the sieve openings, resulting in low impurity removal efficiency and residual impurities affecting product quality. At the same time, during the impurity removal process, the sieve openings are easily blocked by particles or impurities, affecting the continuous impurity removal process. In addition, impurities may adhere tightly to the particle surface and be difficult to remove.

[0004] Therefore, it is necessary to redesign a purification device for the preparation of plastic track granules to address the above-mentioned problems. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for removing impurities in the preparation of plastic track granules.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for removing impurities in the preparation of plastic running track granules includes a mounting base. A blocking device is provided on the upper surface of the mounting base. A first fixing plate and a second fixing plate are symmetrically fixedly mounted on the upper surface of the mounting base. A fixing shaft is rotatably mounted on one side of the second fixing plate. A sieve barrel is fixedly connected to one side of the fixing shaft. A conveying pipe is fixedly connected to the outer wall of the sieve barrel. A control valve is provided on the conveying pipe. Multiple baffles are arranged around the outer wall of the sieve barrel, and the output end of the blocking device abuts against the baffles at corresponding positions. A stirring device is provided on one side of the first fixing plate, and the stirring device passes through one end of the sieve barrel and extends into the sieve barrel.

[0008] like Figure 1-3As shown, the specific implementation method is as follows: by setting up a motor, fixed shaft, fixed block, stirring device and other devices, the motor drives the screen barrel to rotate. The stirring device and the blocking device, and the stirring blades make the plastic track particles roll and move fully in the screen barrel, constantly contacting the screen holes, which effectively improves the efficiency and effect of screening and removing impurities. It can accurately separate impurities from the screen holes. During the rotation of the screen barrel, the vibration effect generated by the interaction between the baffle, the mounting plate and the spring can not only prevent the screen holes from clogging, but also help impurities to quickly leave the particle surface, improving the speed and purity of impurity removal.

[0009] In a preferred embodiment, the blocking device includes a plurality of springs, which are fixedly mounted at equal intervals on the upper surface of the mounting base. One end of each of the springs is fixedly mounted on a mounting plate, and the mounting plate abuts against a baffle plate at a corresponding position.

[0010] In a preferred embodiment, the stirring device includes a drive shaft, which is rotatably mounted on one side of a first fixed plate. One end of the drive shaft passes through one end of a sieve barrel and extends into the sieve barrel. Two connecting plates are symmetrically fixedly mounted on the outer wall of the drive shaft. A fixed sleeve is fixedly mounted on the outer wall of the drive shaft. Two stirring blades are symmetrically fixedly mounted on the outer wall of the fixed sleeve.

[0011] In a preferred embodiment, two fixing blocks are fixedly installed diagonally at the end of the screen barrel away from the fixed shaft, and the two connecting plates abut against the two fixing blocks respectively.

[0012] In a preferred embodiment, a mounting bracket is fixedly installed on one side of the second fixing plate, and a motor is fixedly installed on the mounting bracket, with the output shaft of the motor fixedly connected to one end of the fixing shaft.

[0013] In a preferred embodiment, the first fixing plate and the second fixing plate are respectively provided with a sliding groove on one side, and one end of the mounting plate is slidably connected in the two sliding grooves respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention incorporates a motor, a fixed shaft, a fixed block, and a stirring device. The motor drives the screen barrel to rotate, while the stirring and blocking devices, along with the stirring blades, cause the plastic track particles to tumble and move fully within the screen barrel, continuously contacting the screen holes. This effectively improves the efficiency and effect of screening and impurity removal, precisely separating these fine impurities from the screen holes. During the rotation of the screen barrel, the vibration effect generated by the interaction between the baffle, the mounting plate, and the spring not only prevents the screen holes from clogging but also helps impurities quickly detach from the particle surface, improving the speed and purity of impurity removal.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1-3 A device for removing impurities in the preparation of plastic track granules includes a mounting base 1. A blocking device is provided on the upper surface of the mounting base 1. A first fixing plate 2 and a second fixing plate 3 are symmetrically fixedly mounted on the upper surface of the mounting base 1. A fixing shaft 6 is rotatably mounted on one side of the second fixing plate 3. A sieve barrel 7 is fixedly connected to one side of the fixing shaft 6. A conveying pipe 17 is fixedly connected to the outer wall of the sieve barrel 7. A control valve is provided on the conveying pipe 17. After impurity removal is completed, the control valve is opened, and qualified plastic track granules in the sieve barrel 7 can be conveyed through the conveying pipe 17 to subsequent processing or storage stages, facilitating the collection and processing of granules. The conveying time and speed of the granules can be flexibly controlled by the control valve to adapt to different production needs.

[0022] Multiple baffles 8 are arranged around the outer wall of the sieve barrel 7, and the output end of the blocking device abuts against the baffle 8 corresponding to the position. A stirring device is provided on one side of the first fixed plate 2, and the stirring device passes through one end of the sieve barrel 7 and extends into the sieve barrel 7.

[0023] like Figure 1-3As shown, the specific implementation method is as follows: by setting up a motor 5, a fixed shaft 6, a fixed block 9, a stirring device, etc., the motor 5 drives the screen barrel 7 to rotate. The stirring device, the blocking device, and the stirring blades 16 make the plastic track particles roll and move fully in the screen barrel 7, constantly contacting the screen holes, which effectively improves the efficiency and effect of screening and removing impurities. It can accurately separate impurities from the screen holes. During the rotation of the screen barrel 7, the vibration effect generated by the interaction between the baffle 8, the mounting plate 13, and the spring 12 can not only prevent the screen holes from clogging, but also help impurities quickly detach from the particle surface, improving the speed and purity of impurity removal.

[0024] The blocking device includes multiple springs 12, which are fixedly installed at equal intervals on the upper surface of the mounting base 1. One end of each spring 12 is fixedly mounted on a mounting plate 13, and the mounting plate 13 abuts against the corresponding baffle 8.

[0025] The stirring device includes a drive shaft 10, which is rotatably mounted on one side of the first fixed plate 2. One end of the drive shaft 10 passes through one end of the sieve barrel 7 and extends into the sieve barrel 7. Two connecting plates 11 are symmetrically fixedly installed on the outer wall of the drive shaft 10. A fixed sleeve 15 is fixedly installed on the outer wall of the drive shaft 10. Two stirring blades 16 are symmetrically fixedly installed on the outer wall of the fixed sleeve 15.

[0026] Two fixing blocks 9 are fixedly installed diagonally at the end of the screen barrel 7 away from the fixed shaft 6, and the two connecting plates 11 abut against the two fixing blocks 9 respectively.

[0027] A mounting bracket 4 is fixedly installed on one side of the second fixing plate 3. A motor 5 is fixedly installed on the mounting bracket 4, and the output shaft of the motor 5 is fixedly connected to one end of the fixing shaft 6.

[0028] The first fixing plate 2 and the second fixing plate 3 are respectively provided with a sliding groove 14 on one side, and one end of the mounting plate 13 is slidably connected in the two sliding grooves 14 respectively. This ensures that the mounting plate 13 can slide stably within a certain range when subjected to the elastic force of the spring 12 and the squeezing force of the baffle 8, without deviation or shaking, thereby ensuring the stability of the entire device and the continuity of the vibration effect.

[0029] In use, the motor 5 is mounted on the mounting bracket 4, and the mounting bracket 4 is fixed to one side of the second fixing plate 3. The output shaft of the motor 5 is connected to one end of the fixed shaft 6. When the motor 5 starts, the output shaft drives the fixed shaft 6 to rotate. Since the fixed shaft 6 is fixedly connected to the screen barrel 7, the rotation of the fixed shaft 6 will cause the screen barrel 7 to rotate around the axis of the fixed shaft 6. Multiple baffles 8 are provided on the outer wall of the screen barrel 7. During the rotation of the screen barrel 7, these baffles 8 will rotate together with the screen barrel 7.

[0030] When the screen barrel 7 rotates, the baffle 8 rotates with the screen barrel 7 and comes into contact with and collides with the mounting plate 13. Subsequently, the baffle 8 will squeeze the mounting plate 13, causing the mounting plate 13 to compress the spring 12. The spring 12 is elastic and will generate a reverse elastic force after being compressed, pushing the mounting plate 13 to squeeze the baffle 8. This interaction causes the screen barrel 7 to vibrate during rotation, which can prevent the screen holes of the screen barrel 7 from clogging.

[0031] Two fixed blocks 9 are diagonally fixed at the end of the sieve barrel 7 away from the fixed shaft 6. Two connecting plates 11 are symmetrically fixed on the outer wall of the drive shaft 10, and these two connecting plates 11 abut against the two fixed blocks 9 respectively. When the sieve barrel 7 rotates, due to the abutment relationship between the connecting plates 11 and the fixed blocks 9, the rotation of the sieve barrel 7 will drive the drive shaft 10 to rotate. The fixed sleeve 15 fixed on the outer wall of the drive shaft 10 and the two stirring blades 16 symmetrically fixed on the outer wall of the fixed sleeve 15 will also rotate with the drive shaft 10. The stirring blades 16 rotate inside the sieve barrel 7, stirring the plastic track particles inside the sieve barrel 7, causing the particles to continuously roll and move, fully contacting the screen of the sieve barrel 7, improving the efficiency and effect of screening and removing impurities, and helping impurities to be separated from the screen holes of the sieve barrel 7, while qualified plastic track particles remain inside the sieve barrel 7.

[0032] A conveying pipe 17 is fixedly connected to the outer wall of the sieve barrel 7, and a control valve is provided on the conveying pipe 17. After the impurity removal is completed, the control valve is opened, and the qualified plastic track particles in the sieve barrel 7 can be conveyed to the subsequent processing or storage stage through the conveying pipe 17, which facilitates the collection and processing of particles. The conveying time and speed of particles can be flexibly controlled by the control valve to adapt to different production needs.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
