[0002] The vibrating screening machine for screening plastic particles is a special screening device, mainly used for separating and classifying plastic particles according to different particle sizes. The vibrating screening machine drives the vibrating components to act through a motor, causing the screen frame to vibrate reciprocally, and then enabling the materials to tumble and be stressed on the screen mesh on the screen frame. This vibration generates inertial force and centrifugal force, causing the materials to move linearly, circularly, and in a composite motion on the screen surface. Under the action of vibration, smaller-sized particles will pass through the screen holes and be discharged from below the screen surface, while larger particles cannot pass through the screen holes and can only remain on the screen surface.

[0030] By providing a vibrating screening machine in the embodiments of the present application, the problem that in the use process of traditional vibrating screening machines, their screen meshes are usually not easy to replace, the screen meshes are usually integrally formed with the screen frames, and when replacing the screen meshes, the entire screen frame needs to be replaced. Therefore, when screening plastic particles with different requirements, the operation of replacing the screen frame is cumbersome, time-consuming and laborious, and cannot meet the requirements is solved.

[0031] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific implementation manners.

[0032] Embodiments of the present utility model disclose a vibrating screening machine. As shown in the attached Figures 1-4 figure, it includes a base 1 of the screening machine. A guide rail 2 is provided on the base 1 of the screening machine. A sliding sleeve 3 is sleeved on the guide rail 2. An elastic component for providing support to the sliding sleeve 3 is provided on the guide rail 2. The elastic component includes a limiting plate 201 provided on the guide rail 2 and a first spring 202 fixedly connected between the limiting plate 201 and the sliding sleeve 3;

[0033] With the design of the elastic component of the device, when the sliding sleeve 3 vibrates, it is convenient to bounce up and down along the guide rail 2. During the bouncing process, the first spring 202 is continuously squeezed and stretched, so as to facilitate the screening of plastic particles.

[0034] A plurality of sets of screening outer frames 4 are fixedly connected to the sliding sleeve 3. A screen main body 5 is movably clamped inside the screening outer frame 4. A clamping groove 401 is formed in the screening outer frame 4, and the screen main body 5 is movably clamped in the clamping groove 401;

[0035] Through the clamping design of the clamping groove 401 and the screen main body 5, the screen main body 5 is separated from the screening outer frame 4, thereby ensuring the convenience of installation and subsequent replacement between the screening outer frame 4 and the screen main body 5.

[0036] A vibration driving component is provided on the screening outer frame 4. The vibration driving component includes a motor bracket 6 fixedly connected to the screening outer frame 4. A motor main body 601 is fixedly connected to the motor bracket 6, and an eccentric wheel 602 is provided at the output end of the motor main body 601;

[0037] The overall structure of the designed vibration driving component of the device is simple and easy to maintain. The vibration driving component is powered by the motor main body 601. The motor main body 601 drives the eccentric wheel 602 to rotate and then generates vibration, which is transmitted to the screening outer frame 4 and the screen main body 5 to realize the vibration screening of plastic particles. The motor bracket 6 realizes the installation and limitation of the motor main body 601.

[0038] A locking component for limiting the screen main body 5 is provided on the screening outer frame 4. The locking component includes a locking sleeve 7 arranged inside the screening outer frame 4 and a locking pin 702 movably clamped inside the locking sleeve 7. The locking pin 702 is movably clamped in the screen main body 5. A slider 701 is slidably connected inside the locking sleeve 7. A second spring 703 is fixedly connected between the slider 701 and the inner wall of the locking sleeve 7. The locking pin 702 is fixedly connected to the slider 701. A pull rod 704 is fixedly connected to the slider 701. The pull rod 704 passes through the locking sleeve 7 and extends outward. A locking hole 501 is formed in the screen main body 5, and the locking pin 702 is movably inserted into the locking hole 501.

[0039] Through the design of the locking mechanism, when the screening outer frame 4 and the screen main body 5 are clamped, it is convenient to quickly lock the positions of the screening outer frame 4 and the screen main body 5, and ensure the stability of the locked position, so that the installation of the screening outer frame 4 and the screen main body 5 is convenient and stable.

[0040] Before the external screening frame 4 and the screen body 5 are snap-locked, first pull the pull rod 704, so that the pull rod 704 drives the slider 701 and the locking pin 702 to move and compress the second spring 703. At this time, the external screening frame 4 and the screen body 5 are snap-connected. After complete snap-connection, when the pull rod 704 is released, the second spring 703 resets and pushes the slider 701 and the locking pin 702 to move, so that the locking pin 702 is inserted into the inside of the locking hole 501. Therefore, the installation and locking of the external screening frame 4 and the screen body 5 are convenient. When disassembling, the reverse of the above process can be used.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention.
