[0053] like Fig. 9 As shown, the movable sheet 402 is provided with a plurality of through holes 4021 , the positions of the through holes 4021 are consistent with the positions and diameters of the filter holes 4011 , a second center hole 4022 is provided in the center of the movable sheet 402 , and the movable sheet 402 is rotatably connected to the rotating shaft 302 via the second center hole 4022 .

[0054] like Fig.10 As shown, the positioning column 403 is located inside the cavity 4013 , and one end of the positioning column 403 is fixedly connected to a connecting block 4031 , and the connecting block 4031 includes a third contact surface 4032 and a fourth contact surface 4033 .

[0055] The double-opening door 1061 and the motor 304 are electrically connected to the control center, and the opening and closing of the double-opening door 1061 and the rotation of the motor 304 can be controlled by the control center.

[0056] Embodiment 1: A method for using a particle packaging device.

[0057] Step 1: Rotate the movable sheet 402 to partially cover the filter hole 4011 and reduce the feed opening diameter:

[0058] Specifically, Fig.11 As shown, the positioning column 403 is moved closer to the first arc-shaped portion 40131, and the movable sheet 402 rotates along the rotating shaft 302. When the rotating shaft 302 is about to approach the first arc-shaped portion 40131, it is attracted by the magnetic attraction device on the first arc-shaped portion 40131. At this moment, the filter hole 4011 and the through hole 4021 are staggered, and part of the movable sheet 402 is blocked above the filter hole 4011, thereby causing the diameter of the filter hole 4011 to become smaller, so that normal particles cannot fall from the filter hole 4011.

[0059] Step 2: Pour the finished particles into the hopper 106 and start the motor 304:

[0060] Specifically, the packaging bag is connected to the discharge port 305, and the plastic particles are poured into the hopper 106. The double door 1061 is opened by the control center, and the plastic particles flow from the hopper 106 to the filter cover 401. Some particles smaller than the normal diameter fall from the overlapping part of the filter hole 4011 and the through hole 4021 into the silo 301 below.

[0061] At this time, start the motor 304 to rotate counterclockwise, and the motor 304 drives the rotating shaft 302 to rotate, so that the filter cover 401 and the rubber strip 303 rotate. When the positioning column 403 contacts the telescopic strip 202, since the positioning column 403 is blocked by the filter cover 401, the fourth contact surface 4033 slides on the second contact surface 2022, causing the telescopic strip 202 to retract inwardly. When the fourth contact surface 4033 is no longer in contact with the second contact surface 2022, the telescopic strip 202 returns to its original position through elastic force.

[0062] When the fourth contact surface 4033 just stops contacting the second contact surface 2022, the control motor 304 rotates 340 degrees counterclockwise and then 340 degrees clockwise to return to its original position, and rotates rapidly, reciprocating in sequence. At this time, the telescopic bar 202 will not contact the positioning column 403, and the plastic particles in the filter cover 401 will move in position due to the forward and reverse movements, so that the small-sized plastic particles in the filter cover 401 can fully enter the through hole 4021 and the filter hole 4011, and flow into the silo 301.

[0063] The rubber strip 303 pushes the plastic particles in the silo 301 to make the plastic particles fall from the discharge port 305 and fall into the packing bag. When no more plastic particles fall out of the packing bag, a new packing bag is replaced.

[0064] Step 3: Pack the qualified particles after screening:

[0065] The control center controls the motor 304 to rotate continuously clockwise. When the positioning column 403 contacts the telescopic strip 202, the first contact surface 2021 contacts the third contact surface 4032. The third contact surface 4032 is resisted by the telescopic strip 202, causing the positioning column 403 to approach the second arc portion 40132 in the cavity 4013 until it is attracted by the magnetic attraction device of the second arc portion 40132. At this time, the telescopic strip 202 is blocked by the positioning column 403 and then compressed. When the telescopic strip 202 is no longer in contact with the positioning column 403, the telescopic strip 202 rebounds and the movable sheet 402 rotates. The through hole 4021 is concentric with the filter hole 4011. Normal plastic particles pass through the through hole 4021 and the filter hole 4011 and fall into the silo 301.

[0066] In the same way as in step 2, the control center controls the motor 304 to rotate 340 degrees alternately clockwise and counterclockwise, and the plastic particles of normal size fall into the silo 301 and are pushed by the rubber strip 303 to fall into the packaging bag from the discharge port 305.

[0067] Step 4: Clean the large plastic particles remaining on the filter cover 401:

[0068] When the discharge port 305 stops unloading, the packing bag filled with plastic particles is packed, and the motor 304 is controlled by the control center to stop rotating. At this time, the larger plastic particles still stay on the filter cover 401. After the larger plastic particles are picked out, they are placed in the same packing bag as the smaller plastic particles for processing together.

[0069] The device is provided with a telescopic bar 202 that cooperates with the positioning column 403 to drive the movable plate 402 to rotate, thereby adjusting the feeding size of the plastic particles, screening large and small plastic particles, improving the uniformity of the plastic particles, and solving the technical problem that the particle packaging machine usually directly packs the particles in the hopper 106. During the packaging process, since the particles in the hopper 106 are not screened again, particles of inconsistent sizes will also enter the package, thereby affecting the quality of the entire package of particles.

[0070] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
