CN203046039U - Uniform-screening device for plastic particles - Google Patents

Abstract

The utility model discloses a uniform-screening device for plastic particles. The uniform-screening device comprises a charging hole, a discharging hole, a screening net, a bracket and a vibration motor, wherein the charging hole and the discharging hole are formed in the two ends of the screening net, respectively; the screening net is arranged on the bracket; and the vibrating motor is arranged at the bottom of the bracket. The screening net is of a multi-layer structure, and a material storage box is arranged on the lower surface of each screening net layer; and the size of the meshes of the screening net is gradually increased in sequence from top to bottom. After the uniform-screening device for the plastic particles is modified, the particles are screened out in sequence from small to large during the plastic particle screening process, so that the uniformity degree of the particles is remarkably improved.

Description

Uniform screening equipment for plastic particles

technical field

The utility model relates to a plastic particle screening device in the field of plastic processing.

Background technique

The main components of the plastic pellet production line are: waste plastic classification → automatic crushing and cleaning → thermoplastic molding → automatic pelletizing → finished product packaging.

Among them, the size of the particles needs to be screened between the processes of automatic pelletizing→finished product packaging (capital return). Particle size and uniformity of mixing also have a very important impact on subsequent use. The function of the existing screening equipment is relatively simple, and the screened particles are of uniform size and low quality.

Contents of the invention

The utility model provides a uniform screening device for plastic granules, which aims to make the size of the granules more uniform during the screening process, thereby improving the product quality of subsequent processing.

The technical solution of the utility model:

Uniform screening equipment for plastic particles, including a material inlet, a material outlet, a screen, a bracket, and a vibrating motor. A vibrating motor is installed at the bottom of the support, and it is characterized in that: the screen has a multi-layer structure and a material storage box is arranged under each layer of screen, and the mesh size of the screen increases from high to low.

The number of layers of the screening net is three.

The discharge port of the first layer of screen is directly above the feed port of the second layer.

The discharge port of the second layer is directly above the feed port of the third layer.

The included angle between the plane of the screen and the horizontal plane is 3 to 5 degrees.

The discharge port is lower than the feed port.

The beneficial effects of the utility model:

After the modification of the utility model, during the screening process of plastic particles, the particles will be screened out in sequence from small to large, and the uniformity of the particles will be significantly improved.

Fig. 1 is the structural representation of the utility model.

Detailed ways

The utility model is described in detail below in conjunction with embodiment.

As shown in Figure 1, three layers of screening nets are installed on the support 1, storage boxes are respectively installed under each layer of screening nets, and vibration motors are installed at the bottom of the support.

Example:

As shown in Figure 1, the first screening net 2 is installed on the top of the support 1, and one end of the first screening net 2 is provided with a feed inlet, and the other end is provided with a discharge port 3, and a second screening net 2 is installed below the first screening net 2. A storage box 4, the size of the storage box 4 is the same as the size of the first screen 2, and one end of the storage box 4 is provided with a discharge port 5; the second screen 6 is installed below the storage box 4, One end of the second screen 6 is provided with a discharge port 7, and the direction of the discharge port 7 and the discharge port 3 is opposite, and the second storage box 8 is installed below the second screen 6, and the second storage box 8 One end is provided with a discharge port 9, and the position of the discharge port 9 is directly below the discharge port 7; a third screen 10 is installed below the second storage box 8, and a third storage screen 10 is installed below the third screen. Feed bin 11; the mesh size of the first screen 2 to the third screen 10 increases successively, and if it is necessary to screen particles with a more uniform diameter and smaller size, the screen and the storage box can continue to be increased.

The inlet of the screen is set slightly lower than the outlet, so that during the vibration screening process, the plastic particles can slowly fall to the next screen along the outlet.

In summary, the utility model achieves the desired effect.
