Thus, the automatic material color screening is realized through the matching of the conveying mechanism 10, the recognition mechanism 20 and the screening mechanism 30, the screening speed is high, and the screening error and the screening leakage are less.

Optionally, the conveying mechanism 10 may be a belt conveyor, and the belt conveyor may include a wheel-shaped driving shaft, a conveying belt, and an electric motor, the wheel-shaped driving shaft and the wheel-shaped driven shaft are arranged in parallel, the conveying belt is sleeved on the wheel-shaped driving shaft and the wheel-shaped driven shaft, the electric motor is configured to drive the wheel-shaped driving shaft to rotate, the wheel-shaped driving shaft rotates to drive the conveying belt to rotate, and then the wheel-shaped. In this way, the conveyor belt rotates, forming a race-track type structure capable of circulating rotation.

Optionally, the conveying direction of the conveyor belt is not specifically limited herein, and the conveyor belt may be conveyed in a horizontal direction, or may be conveyed from a high position to a low position or from a low position to a high position in a slope.

Optionally, when the shape of the anti-skid protrusions is strip-shaped, the arrangement direction of the strip-shaped anti-skid protrusions cannot be consistent with the conveying direction; in particular, it may be arranged in strips perpendicular to the transport direction. Thus, when the transmission mechanism suddenly accelerates or decelerates, the frequency of occurrence of slipping between the material and the conveyor belt can be reduced.

Optionally, the transfer mechanism 10 comprises: the conveying belt comprises a conveying belt and blocking strips, wherein the blocking strips are arranged on two sides of the conveying direction of the conveying belt and used for blocking materials and preventing the materials from being separated from the conveying mechanism 10 in the conveying process.

Optionally, the transfer mechanism 10 comprises: the material conveying device comprises a conveying belt and blocking strips, wherein the blocking strips are arranged on two sides of the conveying belt and extend and form along the conveying direction, and the blocking strips can play a role in guiding so that materials on the conveying belt can be conveyed along the setting direction of the blocking strips and cannot deviate from the preset conveying direction.

Alternatively, the identification mechanism 20 may be a visual detection device for identifying and judging the color of the material instead of human eyes. The visual detection device may be an image capture device; for example, a CCD vision detector.

Alternatively, the recognition unit 20 is a CCD vision detector, converts the material to be photographed into an image signal, transmits the image signal to its own image processing system, converts the image signal into a digital signal according to its color information, and controls the sieving operation of the sieving unit 30 according to the color represented by different digital signals. For example, the material to be identified is a plastic bottle, and the material of the selected color is a transparent plastic bottle; the identifying mechanism 20 identifies that the color of the plastic bottle passing through the identifying mechanism is transparent, and when the conveying mechanism 10 conveys the plastic bottle with the transparent color to the screening mechanism 30, the screening mechanism 30 screens the plastic bottle with the transparent color out of the first material outlet 11 and conveys the plastic bottle with the transparent color into the collecting box 40. Specifically, the CCD vision detector can be a CCD vision detector with the model number XG-X1000.

Thus, the automatic material color screening is realized through the matching of the conveying mechanism 10, the recognition mechanism 20 and the screening mechanism 30, the screening speed is high, and the screening error and the screening leakage are less.

Optionally, the conveying mechanism 10 is provided with a first material outlet 11, the first material outlet 11 is arranged at one side of the conveying mechanism 10, and the collecting box 40 is communicated with the first material outlet 11. In this way, the sifting mechanism 30 may be implemented to feed the selected color material into the collection bin 40.

Generally, the normal operation state of the conveying mechanism 10 is a conveying state, and a material is placed on the conveying mechanism 10, and the movement locus of the material is from one end of the conveying mechanism 10 to the other end, which can be referred to as the conveying direction of the conveying mechanism 10, the initial end of the material is an upstream end, and the other end opposite to the upstream end is a downstream end. And both sides parallel to the conveying direction will be referred to as one side and the other side of the conveying mechanism 10.

Optionally, the first discharge port is disposed at one side of the conveying mechanism 10, and may be any one of two sides parallel to the conveying direction; the collecting box 40 is arranged on the same side as the first material outlet 11 and communicates with the first material outlet 11 for receiving material screened out from the first material outlet 11.

Optionally, the end of the conveying mechanism 10 is provided with a second material outlet 12, and the materials of the non-selected colors are conveyed to the second material outlet 12 through the conveying mechanism 10 and are sent out. The collecting box 40 of the previous embodiment may be a first collecting box, and the screening device may further include a second collecting box communicated with the second material outlet 12, and since the second material outlet 12 is arranged at the end of the conveying mechanism 10, the conveying mechanism 10 can send out the materials with non-selected colors by using the acting force of the conveying mechanism 10 on the materials. In this way, it is possible to achieve that the material of the non-selected colour is fed into the second collection bin.

Optionally, a material inlet 13 is provided at the upstream end of the conveying mechanism 10, and a feeding mechanism is connected to the material inlet 13, and the feeding mechanism is in a shape of a gradually narrowing trumpet. Because the material put into the feeding mechanism can be put into a plurality of materials at a time, it is difficult to ensure that the material singly enters the material inlet 13 in sequence, and it is also difficult to ensure that the material on the conveying mechanism 10 is detected by the identification mechanism 20 in sequence singly, therefore, the feeding mechanism is set to be a horn shape which gradually narrows from the position far away from the material inlet 13 to the material inlet 13, the joint of the horn shape and the material inlet 13 is the narrowest position, and the dimension of the horn shape can only accommodate the passage of a single material. Like this, realized that the material that gets into transport mechanism 10 arranges in proper order for single, reduced the condition that a plurality of materials pile up and taken place, realized carrying out the screening of material colour with automizing, screening speed is very fast, and the mistake is sieved, is leaked and sieves less.

When the air injection direction of the nozzle head is adjusted to a direction perpendicular to the conveying direction and toward the first material outlet 11, the air injection unit 31 may be disposed at the other side opposite to the first material outlet 11. When the air injection direction of the spray head is an inclined direction which deviates from the conveying direction, the air injection assembly 31 can be arranged at the position which is slightly close to the upstream of the conveying mechanism 10 and is opposite to the first material outlet 11; conversely, similarly, when the air injection unit 31 is disposed at the opposite side of the first material outlet 11 closer to the upstream of the conveyor 10, the air injection direction of the nozzle head of the air injection unit 31 is adjusted to be directed toward the first material outlet 11. Thus, the air injection direction of the spray head can be adjusted, and the spray head can adapt to different installation positions of the air injection assembly 31.
