Description

Technical Field

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

[0002] TPE plastic particles, namely thermoplastic elastomer. It is a material that can be repeatedly stretched to more than twice its original length at room temperature and almost completely recover to its original length after stress is eliminated. TPE combines the high elasticity, high strength and high resilience of rubber with the processing characteristics of plastics, such as injection molding, no need for vulcanization, and recyclability. It has a wide range of hardness, good colorability, soft touch, weather resistance, fatigue resistance and temperature resistance, and excellent processing performance. TPE materials can be used to replace traditional vulcanized rubber and have been widely used in the electronics, communications and automotive industries.

[0003] The screening device is a vibrating screening mechanical equipment that utilizes the relative movement between bulk material and the screen surface to allow some particles to pass through the screen holes and classify the material into different levels according to particle size. During the production process of plastic particles, the finished plastic particles need to be fed into a cutting device and cut into plastic particles of a fixed size. Since there will be certain errors in the cutting process of the cutting machine, the particles will be inconsistent in size. Therefore, the particles need to be pre-screened. Before screening, the plastic particles are piled together, which will lead to agglomeration. The existing screening device cannot separate the agglomerated plastic particles well, and the screening effect is poor. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 5 A screening device for TPE plastic particles comprises a screening box 1, a feed hopper 2 is installed above the screening box 1, and the feed hopper 2 is fixedly connected to a feed pipe 3 below it, a vibration motor 17 is fixedly installed at the bottom of the screening box 1, and a plurality of screening nets 13 with different apertures are movably plugged inside the screening box 1, a second discharge port 6 is arranged on one side of the screening box 1 above the screening net 13, and a first discharge port 5 is arranged on one side of the screening box 1 below the screening net 13, brackets 4 are arranged at the four corners of the bottom of the screening box 1, and a guard plate 7 is installed at the bottom and one side of the screening box 1.

[0025] like Figure 3 , Figure 4 As shown, the feed hopper 2 and the motor box 8 share a side plate and are installed on the feed pipe 3 at the same time. The feed pipe 3 plays a supporting role at this time. The other side of the motor box 8 is fixedly connected to the screening box by a support rod. The feed pipe 3 and the support rod support the motor box 8 at the same time. A motor 9 is installed inside the motor box 8. The motor 9 is connected to the transmission shaft 10 through a transmission gear 12. Driven by the motor 9, the gear on the output shaft meshes with the transmission gear 12 to drive the rotation of the transmission shaft 10. A stirring blade 11 is fixedly installed on the transmission shaft 10. The stirring blade 11 rotates with the rotation of the transmission shaft to stir up the TPE plastic particles poured from the feed hopper 2.

[0026] like Figure 3 , Figure 5 As shown, three screening nets 13 are installed in the middle of the screening box 1, and the screening nets 13 are supported by partitions 14. The screening nets 13 and the partitions 14 are in the same plane and are installed in the middle of the screening box at the same angle to screen the TPE plastic particles entering from the feed pipe 3. The screening nets 13 are installed at a certain inclination angle, which is beneficial to the forward movement of the TPE plastic particles during the screening process. Side grooves are provided on both sides of the partition 14, and the partition 14 is fixedly installed in the notch on the rear side plate of the screening box 1. The screening net 13 can be pulled out along the side plate of the partition 14, which is convenient for replacing screening nets with different apertures and can adapt to TPE plastic particles of different sizes.

[0027] A bottom plate 15 is provided at the bottom of the screening box 1, and the bottom plate 15 is installed obliquely below the screening net 13, and its inclination angle is the same as that of the screening net 13. The purpose of setting a certain inclination angle is to facilitate the forward movement of TPE plastic particles during screening. The first discharge port 5 is connected to the screening net 13, and the second discharge port is connected to the bottom plate 15. The connected parts are inclined toward the discharge port to facilitate the falling of TPE plastic particles. The vibration motor 17 is fixedly installed on the support plate 16 with bolts. The two sides of the support plate 16 are fixedly connected to the front and rear side plates of the screening box 1.
