[0001] The invention relates to the technical field of TPE particle production, and in particular to a screening device and a screening method for TPE particle production. Background Art

[0002] TPE particles, the full name of which is thermoplastic elastomer particles, are a special plastic material with the dual properties of plastic and rubber. They are mainly used in the automotive industry, electronics and electrical industry, medical industry, toys and children's products. After the production of TPE particles is completed, they need to be screened. A screening machine is needed for screening. The working principle of the TPE particle screening machine is mainly based on the general principle of the screening machine, that is, the vibration of the screen plate is used to screen the material on the screen hole. However, there are still some problems in the use of traditional TPE particle screening machines.

[0003] When a traditional particle screening machine discharges materials through a discharge box, the discharge port is always fixed at the same position on the top of the screening screen. This causes TPE particles to easily accumulate on the top of the screening screen during discharge, making it impossible to quickly and conveniently screen the particles, resulting in poor screening effects. Therefore, a screening device for TPE particle production and a screening method thereof are needed to solve the above problems. Summary of the invention

[0014] S1. When screening TPE particles, pour the TPE particles into the material box, and then start the vibration motor with an external power supply. After starting, the vibration motor will drive the first screening frame to vibrate. After the first screening frame vibrates, the valve at the bottom of the material box is opened. After opening, the TPE particles inside the material box will flow into the inside of the discharge pipe, and then flow out through the discharge port;

[0015] S2. When the material is discharged from the discharge port, the external power supply starts the drive motor, and the drive motor drives the belt pulley to rotate after starting. When the belt pulley rotates, it drives the reciprocating screw rod to rotate through the mounting plate.

When the TPE particles fall to the top of the first screening frame, the vibrating first screening frame will screen the TPE particles, so that the small TPE particles will pass through the screening holes inside the first screening frame and fall into the inside of the second screening frame, thereby screening out the small particles in the TPE particles and completing the screening work;

[0018] S5. When the driving motor rotates, it will also drive the connecting disk to rotate. When the connecting disk rotates, it will drive the fixed disk to rotate through the fixed shaft. When the fixed disk rotates, it will drive the rotating disk to rotate. When the rotating disk rotates, it will drive the disc to rotate. When the disc rotates, it will drive the impact column on one side of the fixed seat to move back and forth inside the fixed sleeve through the cooperation of the fixed column and the movable sleeve, so that one side of the impact column hits the outside of the material box, thereby generating vibration force, so that the TPE particles will not be blocked inside the material box, thereby completing the anti-blocking work.

[0019] The present invention provides a screening device for TPE particle production and a screening method thereof, which have the advantages of:

[0020] The driving motor, the belt pulley and the belt pulley are used in coordination to drive the reciprocating screw rod to rotate. The rotating reciprocating screw rod cooperates with the screw sleeve, so that when unloading, the discharge port can be driven to reciprocate on the top of the first screening frame, so that the TPE particles can be evenly spread on the top of the first screening frame, and will not accumulate in one place to affect the screening effect, thereby achieving a better effect when screening TPE particles;

[0021] Through the coordinated use of the disc, the fixed column and the movable sleeve, the impact column can be driven to reciprocate inside the fixed sleeve when the material box is unloaded, so that the impact column hits the outside of the material box and vibrates the material box to prevent TPE particles from being blocked inside the material box when unloading, thereby improving the anti-blocking effect.
