Background technique

Plastic is a common material in our life. With the continuous development of society, the plastic processing industry has developed vigorously. Plastic granules are the raw materials for the production of plastic products. At the same time, due to different actual needs, in some cases, the plastic particles that are too large or too small should be removed when feeding.

The invention patent of patent application publication number CN 108327122 A discloses a plastic particle feeder with screening function, including a feeder, a screen and a first mesh plate, and the bottom end of the feeder is provided with a feeder The feeding chute is fixedly connected with the feeding machine, the inner bottom of the feeding chute is provided with a motor, the motor is fixedly connected with the feeding chute, and the front end of the motor is provided with a driving wheel , the driving wheel is connected to the motor through transmission, and the left side of the driving wheel is provided with a driven wheel; through mesh plates of three different specifications on the screen, combined with the vibration force generated by the energized operation of the vibration motor, the plastic particles can be effectively Raw materials and impurities are screened, which provides convenience for users. By setting up heating pipes and fans, the heating pipes and fans are energized and operated to generate hot air, and then dry the moisture on the surface of plastic particles, avoiding the adhesion and agglomeration of raw materials. It ensures the normal use of the next process of raw materials and improves the quality of plastic granule production and processing.

The utility model of the patent application publication number CN 214447714 U also discloses a plastic granule processing feeder with a screening function, including a base, a tank body, a conveying pipe and a first discharge port, the top of the base is fixedly connected There is a tank body, one side of the tank body is fixedly connected with a delivery pipe, and the bottom end of the delivery pipe is installed with a drive motor, the inside of the delivery pipe is provided with an auger, and the inside of the tank body is provided with a screening structure , The interior of the tank is provided with a noise reduction structure, and the other side of the tank is provided with a dust removal structure. The utility model can drive the frame to vibrate inside the base through the operation of the vibrator, and the top and bottom ends of the frame edge are provided with springs, and the vibration frequency of the frame is made more stable by using the elasticity of the spring, while the bump can Guide the plastic particles, evenly disperse the plastic particles on the screen, and screen the plastic particles through the screen, so that the feeding machine for plastic particle processing has a screening function.

When the above two schemes sieve the plastic particles before feeding, they are all carried out through a screen, but after actual research by those skilled in the art, it is found that although the use of a screen to sieve the plastic particles can achieve the screening effect, However, it is obvious that due to the difference in the size of the plastic particles, both solutions have the situation that the plastic particles are stuck inside the sieve holes and cause the sieve holes to fail, which in turn has a great impact on the screening efficiency. Follow-up cleaning is performed on this part of the plastic particles It is also inconvenient when recycling.

At the same time, when using the method of solution 1 for feeding, since the plastic particles will roll above the inclined screen, some larger plastic particles will be blocked by other plastic particles and cannot be screened and remain on the top of the inclined screen. In some cases, the actual screening effect is poor, and it is necessary to manually collect and re-screen this part of the plastic particles in the future.

In addition, when using the method in Scheme 2 for feeding, in the case of a large single-time processing volume, the large-grained materials screened out by the screen will all accumulate on the top of the screen, thereby blocking the plastic particles above it. , causing it to fail to fall through the screen, and the actual screening effect is not ideal.

The working principle of the present invention:

During actual use, plastic particles are added to the inside of the feed hopper 31 and hot air is simultaneously input into the inside of the lifting seat 41 through the hot air input pipe 44. The hot air enters the inside of the drying cylinder 45 and the annular drying plate 46, and then passes through multiple drying The branch pipe 47 blows to the spiral material guide pipe 48, and then the redundant hot air enters the inside of the dust filter box 51 through the air flow input pipe 53, and after being filtered by the dust filter bag 52, enters the inside of the sealed housing 61 through the air flow output pipe 54, and passes through a plurality of inlets.
