Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle screening, in particular to a plastic particle screening filter. Background Art

[0002] In the plastic manufacturing process, uniform plastic particle size can ensure that the plastic is evenly heated, plasticized and flows in the barrel. If the particles are of different sizes, small particles may melt first, which will cause surface defects, uneven internal stress and other quality problems in the injection molded products. The screening machine can classify the particles according to the size range to ensure that the particle size used in production meets the specific process requirements and the product quality is stable. The airflow screening machine is a common plastic particle screening machine that uses the effect of airflow to perform screening.

[0003] At present, when the existing airflow screening machine is in use, the staff can first pour the plastic particles that need to be screened into the hopper. However, due to the relatively simple overall structure of the screening machine hopper, when the staff pours a large amount of plastic particles at one time, some plastic particles will not have time to pass through the sieve holes and will accumulate on the screen, thereby hindering the screening of subsequent particles, causing the screening process to be unable to proceed normally and reducing the screening efficiency. To this end, we propose a plastic particle screening filter to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a plastic particle screening filter.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A plastic particle screening filter comprises a screening body, a feeding frame is installed on the top of the screening body, and a hopper is covered on the top of the feeding frame, and a covering plate is covered on the side of the feeding frame, and a motor is installed on the outer wall of the covering plate, and the output end of the motor passes through the covering plate and is connected to a rotating shaft, and a quantitative plate is sleeved on the outer side of the rotating shaft.

[0007] Preferably, a mounting plate is symmetrically connected to the upper side of the blanking frame, and the interior of the mounting plate is connected to the hopper via bolts.

[0008] Preferably, four groups of rubber strips are equidistantly distributed on the end of the quantitative plate, and the edges of the four groups of rubber strips are configured as arc-shaped structures.

[0009] Preferably, the inner side of the rubber strip is connected to a mounting block, the interior of the quantitative plate is provided with a rectangular groove adapted to the mounting block, and the side of the quantitative plate is connected to the mounting block via bolts.

[0010] Preferably, the side of the blanking frame is connected to a first connecting block, and the end of the first connecting block is connected to a cylinder, the other end of the cylinder is connected to a second connecting block, and the side of the second connecting block is fixedly connected to the cover plate.

[0011] Preferably, a guide rod is connected to the inner side of the cover plate, and a movable groove adapted to the guide rod is provided on the inner wall of the blanking frame.

[0012] Preferably, two groups of guide rods are provided, and the two groups of guide rods are symmetrically distributed about the central axis of the blanking frame.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The device is equipped with a rotating shaft and a quantitative plate. During use, the rotating shaft and the quantitative plate cooperate with each other to control the falling amount of plastic particles to prevent excessive plastic particles from directly entering the interior of the screening body and accumulating on the filter screen to cause blockage, thereby effectively ensuring the overall screening efficiency of the screening body.

[0015] 2. The device is provided with a first connecting block and a cylinder. After the processing is completed, the staff can start the cylinder to move the covering plate away from the blanking frame, so that the quantitative plate can be pulled out from the inside of the blanking frame, thereby making it convenient for the staff to clean the residual material in the inner cavity of the blanking frame and the outer wall of the quantitative plate, so as to facilitate the subsequent reuse of the device.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 A plastic particle screening filter comprises a screening body 1, a feeding frame 2 is installed on the top of the screening body 1, and a hopper 3 is covered on the top of the feeding frame 2. The specific screening principle of the screening body 1 is the existing technology and will not be described in detail here. The side of the feeding frame 2 is covered with a covering plate 4, and the outer wall of the covering plate 4 is installed with a motor 5, and the output end of the motor 5 passes through the covering plate 4 and is connected to a rotating shaft 6. A quantitative plate 7 is provided on the outer side of the rotating shaft 6. The rotation principle of the motor 5 is also the existing technology and will not be described in detail here.

[0023] Further, refer to Figure 2 It can be seen that the upper side of the discharge frame 2 is symmetrically connected with a mounting plate 14, and the interior of the mounting plate 14 is connected to the hopper 3 by bolts. When in use, the two sets of mounting plates 14 and bolts cooperate with each other to facilitate the staff to separate the hopper 3 and the discharge frame 2, so as to complete the disassembly and cleaning of the hopper 3.

[0024] Further, refer to Figure 4 It can be seen that four groups of rubber strips 8 are evenly distributed at the end of the quantitative plate 7, and the edges of the four groups of rubber strips 8 are set to an arc structure. By setting the four groups of rubber strips 8, the edge of the quantitative plate 7 can be protected, thereby effectively preventing the end of the quantitative plate 7 from directly and rigidly rubbing against the inner wall of the blanking frame 2, so as to protect the inner wall of the blanking frame 2. Since the edge of the rubber strip 8 is set to an arc shape, the smoothness of the rotation of the rubber strip 8 can be effectively guaranteed.

[0025] Further, refer to Figure 2 and Figure 4 It can be seen that the inner side of the rubber strip 8 is connected to the mounting block 9, and the interior of the quantitative plate 7 is provided with a rectangular groove adapted to the mounting block 9. The side of the quantitative plate 7 is connected to the mounting block 9 by bolts. When in use, the mutual cooperation between the mounting block 9 and the bolts can facilitate the staff to promptly remove and replace the damaged and deformed rubber strip 8, so as to achieve the protection effect of the quantitative plate 7.

[0026] Further, refer to Figure 3It can be seen that the side of the blanking frame 2 is connected to the first connecting block 10, and the end of the first connecting block 10 is connected to the cylinder 11, the other end of the cylinder 11 is connected to the second connecting block 12, and the side of the second connecting block 12 is fixedly connected to the cover plate 4. The specific extension and contraction principle of the cylinder 11 is also a very mature technology. By starting the cylinder 11, the second connecting block 12 and the cover plate 4 can be driven to move at the same time, so that the cover plate 4 is forced to cover the opening on the side of the blanking frame 2, or away from the blanking frame 2, so that the staff can clean and maintain the quantitative plate 7 pulled out from the inside of the cover plate 4.

[0027] Further, refer to Figure 3 It can be seen that the inner side of the cover plate 4 is connected to a guide rod 13, and the inner wall of the blanking frame 2 is provided with a movable groove adapted to the guide rod 13. Through the mutual cooperation of the guide rod 13 and the movable groove, the stability of the cover plate 4 during lateral movement can be effectively guaranteed.

[0028] Further, refer to Figure 3 It can be seen that there are two groups of guide rods 13, and the two groups of guide rods 13 are symmetrically distributed about the central axis of the blanking frame 2. The provision of the two groups of guide rods 13 and the moving groove can further ensure the stable movement of the cover plate 4.

[0029] Working principle: When the present invention is in use, the staff can first place the device in a suitable position, and then pour the plastic particles into the interior of the hopper 3, and then the plastic particles can fall onto the quantitative plate 7 provided in the discharge frame 2 by gravity. By starting the motor 5, the rotating shaft 6 and the quantitative plate 7 can be driven to rotate continuously, so that the plastic particles accumulated in the gap of the quantitative plate 7 can fall from the outlet at the bottom of the discharge frame 2 to the interior of the screening body 1 for screening by gravity. Through the rotation of the quantitative plate 7, the amount of plastic particles discharged each time can be the amount of the fan-shaped gap of the quantitative plate 7, so as to effectively prevent excessive plastic particles from entering the interior of the screening body 1;

[0030] After the screening work is completed, some plastic particles with water will adhere to the quantitative plate 7. At this time, the staff can start the cylinder 11 to push the second connecting block 12 and the cover plate 4 to move horizontally, so that the cover plate 4 and the blanking frame 2 are separated, and the rotating shaft 6 and the quantitative plate 7 are pulled out from the inside of the blanking frame 2. At this time, the staff can quickly clean the materials attached to the quantitative plate 7 and the inner cavity of the blanking frame 2. The above is the entire working principle of the present utility model.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated on.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
