Technical Field
[0001] The utility model relates to the technical field of screening devices, in particular to a plastic particle screening device. Background Art
[0002] The plastic particle screening device is used for screening plastic particles. Plastic particles refer to granular plastics, generally divided into more than 200 types, and subdivided into thousands of types; common plastic particles include general plastics, engineering plastics, and special plastics; General plastics: polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, polyurethane; Engineering plastics: nylon, polytetrafluoroethylene, polyoxymethylene, polycarbonate, silicone.
[0003] When the existing plastic particle screening device is in use, when the plastic particles are directly screened in the screening rack, the residence time of the plastic particles is short, resulting in incomplete screening of the plastic particles. At the same time, the dust generated during the screening of the plastic particles is relatively large, causing environmental pollution problems.
[0004] Based on this, a plastic particle screening device with a dust removal and material blocking mechanism is designed. Summary of the Utility Model
[0005] The utility model aims at the deficiencies of the existing technology and provides the following technical solutions: A plastic particle screening device, including a support frame, a screening rack for screening plastic particles is arranged on the upper part of the support frame, one end of the screening rack is rotatably connected to the support frame, the other end of the screening rack is connected to the support frame through a vibration mechanism, a sealing cover plate for sealing is installed on the upper part of the screening rack, a dust removal cover for dust removal is installed in the middle of the sealing cover plate, a material bellows is installed at one end of the sealing cover plate away from the vibration mechanism, the material bellows is connected to a feeding pipe, and a material blocking mechanism for extending the material screening time is installed in the screening rack.
[0006] As an improvement of the above technical solution, the vibration mechanism includes a motor installed on the upper surface of the support frame, a turntable is fixed to the output shaft of the motor, a connecting rod is rotatably installed on the outer edge of the turntable, and the upper end of the connecting rod is rotatably connected to the screening rack.

[0008] As an improvement of the above technical solution, a first screening mesh plate and a second screening mesh plate are arranged inside the screening rack, and the first screening mesh plate is located above the second screening mesh plate, and a discharge pipe is installed at the bottom of the screening rack.
[0009] As an improvement of the above technical solution, the material blocking mechanism includes a baffle rotatably installed in the screening frame. A chute is provided on the side surface of the screening frame, and an adjusting bolt fixedly connected to the baffle is installed in the chute. The baffle is located above the first screening mesh plate.
[0010] The beneficial effects of the present utility model are as follows:
[0011] 1. Through the vibration mechanism installed between the support frame and the screening frame, the screening frame shakes on the upper part of the support frame through the vibration mechanism, so as to facilitate the screening of plastic particles when they enter the interior of the screening frame from the material bellows. When the material bellows is connected to the feeding pipe, its own deformation can relieve the vibration of the screening frame, so that the plastic particles enter the screening frame from the material bellows. The material blocking mechanism installed in the screening frame enables the plastic columns to extend the screening time through the material blocking mechanism during the screening inside the screening frame, thereby improving the fullness of the screening of plastic particles.
[0012] 2. Through the vibration mechanism composed of a motor, a turntable and a connecting rod, the turntable is fixed on the output shaft of the motor, and the connecting rod is rotatably installed on the outer edge of the turntable. The upper end of the connecting rod is rotatably connected to the screening frame. Therefore, when the output shaft of the motor drives the turntable to rotate, the turntable drives the screening frame to rotate through the connecting rod, which is convenient for the screening frame to vibrate and screen the plastic particles. The motor is a double-headed motor, which is convenient for the two heads of the motor to drive the turntable to rotate.
[0013] 3. Through the first screening mesh plate and the second screening mesh plate arranged in the screening frame, it is convenient for the first screening mesh plate and the second screening mesh plate to cooperate to screen the plastic particles. The coarse material of the plastic particles stays on the first screening mesh plate, the fine material of the plastic particles stays on the second screening mesh plate, and the powder material of the plastic particles reaches the inside of the screening frame, which is convenient for screening the plastic particles.
[0014] 4. Through the material blocking mechanism composed of a baffle, a chute and an adjusting bolt, the baffle is rotatably installed in the screening frame, and the adjusting bolt fixed at one end of the baffle is installed in the chute. Therefore, it is convenient to adjust the angle of the baffle through the adjusting bolt, and it is convenient to extend the residence time of the plastic particles in the screening frame after adjusting the baffle.

A sealing cover plate 12 for blocking is installed on the upper part of the screening frame 2, a dust removal cover 14 for dust removal is installed in the middle of the sealing cover plate 12, a material bellows 13 is installed at one end of the sealing cover plate 12 away from the vibration mechanism, the material bellows 13 is connected to a feeding pipe, and a material blocking mechanism for extending the material screening time is installed in the screening frame 2.
[0022] In this implementation manner, through the vibration mechanism installed between the support frame 1 and the screening frame 2, the screening frame 2 shakes on the upper part of the support frame 1 through the vibration mechanism, so as to facilitate the screening of plastic particles when entering the inside of the screening frame 2 from the material bellows 13. When the material bellows 13 is connected to the feeding pipe, its own deformation can relieve the vibration of the screening frame 2, so that the plastic particles enter the screening frame 2 from the material bellows 13. The material blocking mechanism installed in the screening frame 2 enables the plastic columns to extend the screening time through the material blocking mechanism when screening inside the screening frame 2, thereby improving the fullness of the screening of plastic particles and achieving a better dust removal effect.
[0023] Specifically, the vibration mechanism includes a motor 3 installed on the upper surface of the support frame 1. A turntable 4 is fixed to the output shaft of the motor 3. A connecting rod 5 is rotatably installed on the outer edge of the turntable 4. The upper end of the connecting rod 5 is rotatably connected to the screening frame 2. The motor 3 is a double-headed motor, and there are two turntables 4 and connecting rods 5.
[0024] In this embodiment, a vibration mechanism composed of a motor 3, a turntable 4, and a connecting rod 5 is adopted. The turntable 4 is fixed on the output shaft of the motor 3, and the connecting rod 5 is rotatably installed on the outer edge of the turntable 4. The upper end of the connecting rod 5 is rotatably connected to the screening frame 2. Therefore, when the output shaft of the motor 3 drives the turntable 4 to rotate, the turntable 4 drives the screening frame 2 to rotate through the connecting rod 5, which is convenient for the screening frame 2 to vibrate and screen the plastic particles. The motor 3 is a double-headed motor, which is convenient for the double heads of the motor 3 to drive the turntable 4 to rotate.
[0025] Specifically, a first screening mesh plate 6 and a second screening mesh plate 7 are arranged inside the screening frame 2, and the first screening mesh plate 6 is located above the second screening mesh plate 7. A discharge pipe 8 is installed at the bottom of the screening frame 2.
[0026] In this embodiment, through the first screening mesh plate 6 and the second screening mesh plate 7 arranged in the screening frame 2, it is convenient for the first screening mesh plate 6 and the second screening mesh plate 7 to cooperate to screen the plastic particles.
