Description

Technical Field

[0001] The utility model belongs to the technical field of plastic particle production, and particularly relates to a plastic particle vibrating screen. Background Art

[0002] In plastic extrusion production, in order to ensure the uniform diameter of the prepared plastic particles and improve product quality, it is necessary to screen and classify the prepared plastic particles through a vibrating screen.

[0003] At present, when the existing plastic particle vibrating screens are in use, all the plastic particles are directly poured onto the screen plate for vibrating screening. This method causes all the plastic particles to accumulate in the same position, thus greatly affecting the screening efficiency of the screen plate and the uniformity of screening. In addition, the screen plates of the existing vibrating screens are directly welded to the machine body and can only screen plastic particles of one specification, greatly affecting the utilization rate of the device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a plastic particle vibrating screen to solve the technical problems raised in the background art.

[0005] To achieve the above purpose, the specific technical solution of the utility model is as follows: A plastic particle vibrating screen includes a support table. A support frame is arranged at the bottom of the support table. A storage bin is arranged at one end of the support table and is snap-connected thereto. A feed hopper is arranged at the top end of the storage bin. A discharge port is arranged at one side of the bottom of the storage bin. A vibrating frame is arranged in the inner cavity of the support table. A screen plate detachably connected thereto is arranged on the upper surface of the vibrating frame. A baffle is arranged at the tail end of the vibrating frame in the inner cavity of the support table. A first discharge bin is arranged on one side of the baffle and a second discharge bin is arranged on the other side. L-shaped frames are arranged at the four corners of the upper surface of the vibrating frame. Support plates corresponding to the L-shaped frames are arranged on both side walls of the support table. A support rod is arranged on the upper surface of the support plate. The top end of the support rod is connected to the horizontal part of the L-shaped frame through a vibration spring. A middle plate is arranged at the middle part of the vibrating frame. A vibration motor is installed at the middle part of the bottom of the middle plate.

[0006] Preferably, the bottom of the inner cavity of the storage bin is set as an inclined plane.

[0007] Preferably, a clamping plate is arranged at the bottom of the storage bin. A clamping notch is arranged at the bottom of the clamping plate. The width of the clamping notch is consistent with the thickness of the wall of the support table.

[0008] Preferably, the support table is a frame structure with an open top end. The bottom inner wall of the support table below the screen plate is set as an inclined plane, and the tail end of the inclined plane is connected to the second discharge bin.

[0009] Preferably, a first discharge port is provided on one side of the bottom of the first discharge bin, and a second discharge port is provided on one side of the bottom of the second discharge bin, and the first discharge port and the second discharge port are located on both sides of the bottom of the support platform.

[0011] The utility model of a plastic particle vibrating screen has the following advantages:

[0012] 1. The utility model can put plastic particles into the storage box through the feeding hopper through the setting of the storage box. With the cooperation between the inclined surface and the discharge port, the phenomenon of plastic particles rushing down can be effectively avoided, so that the plastic particles can enter the screen plate evenly and orderly, and can effectively prevent the plastic particles from being concentrated and stacked in the same position, resulting in poor screening efficiency.

[0013] 2. The utility model provides a detachable connection between the storage box and the support platform, and the installation groove is provided to facilitate the installation and disassembly of the screen plate, so that it is easy to replace the screen plates with different aperture sizes for screening as needed, which greatly improves the flexibility of the structure and has strong practicality.

A storage bin 3 is provided at one end of the support platform 1 and is snap-connected thereto. A clamping plate 11 is provided at the bottom of the storage bin 3, and a clamping opening 12 is provided at the bottom of the clamping plate 11. The width of the clamping opening 12 is consistent with the thickness of the wall of the support platform 1. Through the setting of the clamping opening 12 on the clamping plate 11, the storage bin 3 can be snap-connected to the wall of the support platform 1, facilitating its installation and disassembly, and thus facilitating the installation and replacement of the screen plate 6. A feed hopper 4 is provided at the top of the storage bin 3, and a discharge port 5 is provided at one side of the bottom of the storage bin 3. The bottom inner cavity of the storage bin 3 is set as an inclined surface 13. Through the setting of the storage bin 3, plastic particles can be put into the storage bin 3 through the feed hopper 4. With the cooperation between the inclined surface 13 and the discharge port 5, the phenomenon that plastic particles rush down all at once can be effectively avoided, enabling the plastic particles to enter the screen plate 6 evenly and orderly, effectively preventing the phenomenon that plastic particles concentrate and stack at the same position, resulting in poor screening efficiency. In this way, the plastic particles entering the screen plate 6 will move forward under the action of vibration, and the plastic particles entering the screen plate 6 later will continue to move forward, so that the plastic particles on the screen plate 6 are evenly dispersed, which is beneficial to the rapid screening of the screen plate 6, improves the working efficiency, and ensures the evenness of screening.

Under the action of the baffle 15, the plastic particles with a size smaller than the aperture of the screen plate 6 can be separated from the plastic particles with a size larger than the aperture of the screen plate 6. The plastic particles entering the inclined surface enter the second discharge bin 17 through the inclined surface. On one side of the bottom of the first discharge bin 16, a first discharge port 18 is provided. On one side of the bottom of the second discharge bin 17, a second discharge port 19 is provided. The first discharge port 18 and the second discharge port 19 are located on both sides of the bottom of the support table 1. Through the settings of the first discharge port 18 and the second discharge port 19, it is convenient to classify and collect plastic particles of two different particle sizes.

[0029] At the four corners of the upper surface of the vibration frame 14, L-shaped frames 7 are all provided. On both side walls of the support table 1, support plates 8 corresponding to the L-shaped frames 7 are provided. On the upper surface of the support plate 8, support rods 9 are provided.
