Description

Technical Field

[0001] The utility model belongs to the technical field of screening, and in particular relates to a screening device for producing and processing plastic particles. Background Art

[0002] Plastic particles refer to granular plastics. Since different plastic particles have different particle diameters, they need to be screened when they need to be classified, placed or stored.

[0003] The Chinese patent with application number CN202223509383.4 discloses a plastic particle screening device, including a drawer table, a group of symmetrically arranged U-shaped frames are fixedly connected to the top of the drawer table, guide blocks are respectively arranged on the inner side of the U-shaped frames, one end of the guide blocks is connected to a screening box, and slide grooves are respectively opened on both sides of the screening box. The utility model drives the rotation of the rotating shaft and the elliptical rotating disk by the second motor, so that the guide blocks can drive the screening box to move up and down repeatedly, which is conducive to the screening box to shake up and down, and accelerate the screening speed of the screening box. The first motor can drive the screening box to move forward and backward through the pull plate, which is conducive to the plastic particles following the forward and backward movement of the screening box when the screening box moves forward and backward, ensuring that the particles will push the large particles staying at the screening port, which is conducive to the falling of small particles, reducing the time-consuming and labor-intensive problem of manual shifting, and at the same time, the forward and backward shaking of the screening box can also achieve rapid screening and improve screening efficiency. However, when the above device is actually used, the up and down movement and the forward and backward movement of the screening box can only be performed separately, and the staff needs to manually switch the up and down movement or the forward and backward movement of the screening box. Each time the screening is switched, the motor needs to be shut down and restarted. Each switch is more troublesome, which affects the screening efficiency of the device.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] The utility model will now be further described in detail with reference to the accompanying drawings.

[0027] A limiting groove 15 is provided in the connecting rod 4, the limiting groove 15 cooperates with the limiting rod 3, a vibration assembly 5 cooperating with the limiting rod 3 is installed in the limiting groove 15, a screening box 10 is slidably fitted in the screening frame 6, a collection box 11 is slidably fitted in the base 1, and the collection box 11 is located below the screening frame 6.

[0028] The application of one aspect of the present embodiment is as follows: first, the plastic particles to be screened are poured into the screening box 10, and then the motor 8 is started. The rotation of the output end of the motor 8 will mobilize the transmission component 9, so that the transmission component 9 drives the screening frame 6 to move up and down for screening. The screening frame 6 moves and drives the screening box 10 to screen the plastic particles. While the screening frame 6 moves, the connecting rod 4 will slide along the limiting rod 3 through the limiting groove 15, so that the screening frame 6 and the screening box 10 can move back and forth for screening. During the movement of the connecting rod 4, the limiting rod 3 will drive the connecting rod 4 to vibrate through the vibration component 5, and the vibration of the connecting rod 4 drives the screening frame 6 and the screening box 10 to vibrate, and the plastic particles in the screening box 10 are vibrated and screened. The smaller particles in the screening pass through the sieve holes of the screening box 10 and enter the aggregate box 11. The larger particles that cannot pass through the sieve holes of the screening box 10 remain in the screening box 10. The screening box 10 can be taken out from the screening frame 6 for cleaning later, which is convenient for the staff to use.

[0029] By means of the limit slot 15, when the motor 8 drives the screening frame 6 and the screening box 10 to screen, the connecting rod 4 can slide along the limit rod 3 through the limit slot 15, so that the plastic particles in the screening box 10 can be moved up and down and forward and backward at the same time, without the need for staff to replace them, thereby improving the screening efficiency of the device; by means of the vibration component 5, when the connecting rod 4 slides along the limit rod 3 through the limit slot 15, the vibration component 5 drives the screening frame 6 to vibrate through the connecting rod 4, thereby vibrating and screening the plastic particles in the screening box 10, reducing the situation where larger plastic particles clog the sieve holes; by means of the transmission component 9, the motor 8 can mobilize the transmission component 9, so that the transmission component 9 drives the screening frame 6 to move up and down for screening, thereby enabling the screening frame 6 to drive the screening box 10 to move and screen the plastic particles.

[0030] like Figure 4 As shown, the vibration assembly 5 of this embodiment includes a plurality of round-headed rods 501 installed on the inner wall of the limiting groove 15, and the plurality of round-headed rods 501 are equidistantly distributed, and the peripheral side of the limiting rod 3 cooperates with the plurality of round-headed rods 501. Through the provided round-headed rods 501, when the screening frame 6 drives the connecting rod 4 to move, the limiting rod 3 drives the connecting rod 4 to vibrate through the round-headed rods 501, and the connecting rod 4 drives the screening frame 6 and the screening box 10 to vibrate, so as to screen the plastic particles in the screening box 10.

[0031] like Figure 2-3As shown, the transmission assembly 9 of this embodiment includes a turntable 901 installed at the output end of the motor 8, a push rod 902 installed at one side of the turntable 901, and a slide groove 903 provided at one side of the screening frame 6, and the push rod 902 is slidably matched in the slide groove 903. Through the transmission assembly 9, the output end of the motor 8 can drive the turntable 901 to rotate, the rotation of the turntable 901 drives the push rod 902 to move, and the push rod 902 moves through the slide groove 903 to push the screening frame 6 to move, so that the screening frame 6 drives the screening box 10 to screen.

[0032] like Figure 2-4 As shown, a collecting hopper 12 is installed on the top of the base 1 of this embodiment, and the collecting hopper 12 is located below the screening frame 6 and above the collecting box 11. Through the setting of the collecting hopper 12, the plastic particles screened by the screening box 10 can be collected by the collecting hopper 12 and enter the collecting box 11.

[0033] like Figure 1 As shown, the bottom of the base 1 of this embodiment is equipped with four supporting legs 13, which are respectively installed at the diagonal positions of the bottom of the base 1, and the bottom ends of the four supporting legs 13 are all equipped with anti-skid pads 14. By providing the anti-skid pads 14, the anti-skid pads 14 at the bottom of the supporting legs 13 can make contact with the ground after the device is placed, thereby increasing the friction between the device and the ground and increasing the stability of the device during screening.

[0034] like Figure 2 As shown, both sides of the screening box 10 of this embodiment are equipped with handles 16. Through the provided handles 16, the staff can pull the handles 16 to pull the screening box 10 out of the screening frame 6 to clean up the larger plastic particles remaining in the screening box 10.
