Description

Technical Field

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

[0002] The screening machine uses the relative movement between the granular material and the screen surface to allow some particles to pass through the screen holes and be classified into different levels according to the particle size. The particle level of the screening depends on the screen surface, which is divided into three types: grate, plate screen and mesh screen. Different plastic products require different plastic particle sizes. In order to facilitate the use of manufacturers, screening machines are usually used to grade and screen plastic particles according to the particle size requirements.

[0003] Since plastic particles are light in weight and are not easy to fall through the sieve holes during screening, traditional screening machines are not easy to screen, and traditional particle screening equipment mostly uses a fixed screen structure, which uses a vibration motor to vibrate the screen to achieve particle screening. However, this screening method has problems such as low screening efficiency, easy clogging of the screen, and insufficient screening accuracy. Utility Model Content

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] This embodiment relates to a swing type particle screening machine, the overall structure of which is as follows: Figure 1 As shown, it includes a frame 1, a screening bin 2, a first driving member 5, a vibration motor, and a scraping mechanism 7.

[0040] Among them, the frame 1 is arranged tilted, the screening bin 2 is slidably arranged on the frame 1, the top and bottom of the screening bin 2 are respectively provided with a feed port 3 and a discharge port 4, the first driving member 5 drives the screening bin 2 to slide back and forth on the frame 1, the vibration motor is fixedly arranged on the screening bin 2, and the scraping mechanism 7 is slidably arranged in the screening bin 2 to push the particles to the discharge port 4.

[0041] It is worth mentioning that the top surface of the frame 1 is inclined, and the screening bin 2 slides back and forth at the inclined position. The inclined setting can ensure that the plastic particles enter from the feed port 3 and are discharged from the discharge port 4 after screening, thereby avoiding residual particles in the screening bin 2. The screening bin 2 can shake the plastic particles in the bin when swinging, thereby improving the screening efficiency. The feed port 3 is located at the upper part of the screening bin 2, and the discharge port 4 is located at the lower part of the screening bin 2. With the inclined setting of the frame 1, the screening quality can be improved. The first driving member 5 can drive the screening bin 2 to slide back and forth, thereby realizing back and forth swinging, and with the vibration motor, it can be ensured that the particles can be shaken and mixed in the screening bin 2 and vibrated to screen, thereby improving the screening efficiency. The scraping mechanism 7 can ensure that no particles remain in the screening bin 2 to avoid blockage.

[0042] Based on the above overall introduction, an exemplary structure of the swing type particle screening machine of this embodiment is as follows: Figure 2 As shown, the first driving member 5 includes a driving motor 501 fixedly arranged on the frame 1, a roller shaft 502 rotatably arranged on the frame 1, and a pulley 503 fixedly arranged on the driving motor 501 and the roller shaft 502. A swinging member is also arranged on the roller shaft 502, and a pull rod 504 is rotatably arranged between the screening bin 2 and the swinging member.

[0043] It should be noted that the drive motor 501 is fixedly mounted on the frame 1, and the roller shaft 502 is horizontally mounted on the frame 1 through a bearing. The drive shaft of the drive motor 501 is parallel to the axial direction of the roller shaft 502. The pulley 503 is keyed to the drive motor 501 and the roller shaft 502. The two pulleys 503 are driven by a synchronous belt, that is, the drive motor 501 can drive the roller shaft 502 to rotate, and the swinging member is mounted on the roller shaft 502. The pull rod 504 swings with the swinging member, thereby realizing that the drive motor 501 drives the screening bin 2 to swing.

[0044] As a preferred example, Figure 3 As shown, the swing member of this embodiment includes a disk 505 fixedly arranged on the roller shaft 502, an eccentric shaft 506 fixedly arranged on the end surface of the disk 505, and a pull rod 504 rotatably connected to the eccentric shaft 506. A wheel 507 is fixedly arranged at the bottom of the screening bin 2, the wheel 507 abuts against the inclined surface of the frame 1, and the pull rod 504 pulls the screening bin 2 to slide back and forth on the inclined surface of the frame 1.

[0045] Specifically, the central axis of the disc 505 and the central axis of the roller 502 are centrally arranged, the eccentric shaft 506 is located at a position where the disc 505 deviates from the central axis of the disc 505, and the pull rod 504 is inserted on the eccentric shaft 506. When the disc 505 rotates, the eccentric shaft 506 rotates around the central axis of the disc 505, thereby driving the pull rod 504 to slide back and forth, and the pull rod 504 is connected to the rotating shaft of the screening bin 2, so that the screening bin 2 can be driven to slide back and forth on the frame 1, and the wheel 507 is installed at the bottom of the screening bin 2, and a track is set on the inclined surface at the top of the frame 1. The wheel 507 rotates on the track to ensure that the screening bin 2 can move along the track.

[0046] As a preferred example, Figure 7 As shown, the screening bin 2 of this embodiment is divided into an upper bin 201 and a lower bin 202, a screen 203 is fixedly arranged between the upper bin 201 and the lower bin 202, and there are two discharge ports 4, which are respectively opened on the upper bin 201 and the lower bin 202. Specifically, the plastic particles enter the upper bin 201 from the feed port 3, and the small particles fall from the screen 203 to the lower bin 202 through the swing and vibration of the screening bin 2. When the screening is completed, the particles in the upper bin 201 and the lower bin 202 are respectively discharged from the discharge port 4. A baffle can be installed at the discharge port 4 of the upper bin 201, and the baffle is opened to discharge the particles after the screening is completed.

It should be noted that the scraper 701 is located at the top of the screening bin 2, and the second driving member 702 drives the scraper 701 to slide in the screening bin 2. The bottom of the scraper 701 fits the screen 203. Since the aperture of the screen 203 will clamp the particles, the scraper 701 can be used to push the particles to the discharge port 4 for discharge, and the bottom of the lower bin 202 is a plane, so no residue will be generated. The second driving member 702 is located on the side of the screening bin 2, so a chute 703 is opened on the side of the screening bin 2, and the scraper 701 can extend out of the chute 703 to connect with the second driving member 702, that is, the scraper 701 slides in the chute 703.

Specifically, the slider 704 slides along the length direction of the slide groove 703, and the slider 704 and the scraper 701 can be connected by a key to ensure the stability of the scraper 701 when sliding and avoid the scraper 701 from rotating when sliding. The moving end of the second driving member 702 is connected to the slider 704, so that the second driving member 702 drives the scraper 701 to move.

[0049] As a preferred example, Figure 6 As shown, the second driving member 702 of this embodiment includes a reduction motor 7021 fixedly arranged on the screening bin 2, a transmission rod 7022 rotatably arranged on the screening bin 2, sprockets 7023 are respectively arranged at both ends of the transmission rod 7022 and on both sides of the screening bin 2, the two sprockets 7023 on the same side are driven by a chain, and the slider 704 is fixedly connected to the chain.

[0050] Specifically, the reduction motor 7021 is fixedly installed on the screening bin 2, the transmission rod 7022 and the reduction motor 7021 are key-connected, thereby driving the transmission rod 7022 to rotate, and sprockets 7023 are set at both ends of the transmission rod 7022 to ensure that the reduction motor 7021 can drive the two ends of the scraper 701 to move at the same time, ensuring the uniformity of force, and the rotating shaft on the screening bin 2 is connected to another sprocket 7023, and the two sprockets 7023 are meshed with a chain, thereby realizing the chain transmission between the two sprockets 7023, and the slider 704 can be fixedly installed at the rotating shaft connection of the chain, so that the chain drives the slider 704 to move, ensuring that the scraper 701 can move in the screening bin 2.

[0051] The swing-type particle screening machine in this embodiment ensures that the screening bin 2 can swing back and forth on the frame 1 through the coordinated arrangement of the first driving member 5 and the screening bin 2, so that the particles can shake in the screening bin 2 and the screening efficiency is improved. The setting of the vibration motor 6 ensures that the particles in the screening bin 2 can be screened according to the size of the screen 203 and the screening quality is improved. The setting of the scraping mechanism 7 ensures that the particles in the upper bin 201 can be discharged from the screening bin 2 and residual particles in the screening bin 2 are avoided.
