Choose plastic, which is better for color sorter with crawler type or chute type?

At present, the color sorters on the market are mainly divided into two types: crawler color sorters and chute color sorters. Is it better to use a crawler type or a chute type for the color sorter? Which one is more efficient to use? Compared with the traditional chute color sorter, the crawler color sorter can highlight the advantages of the crawler in terms of color sorting accuracy, sorting damage rate, and processing output per hour. Therefore, the crawler color sorter is accepted by more and more customers, and the market share is gradually expanding.

The following editor introduces a sliding slot color sorter and a crawler color sorter, and the difference between the two.

1. What is a chute color sorter?

The chute color sorter uses gravity to make materials slide at a high speed along the chute. Some materials cannot slide at a constant speed or jump up and down during the sliding process, which makes the color sorting accuracy not high.

There are two very important links when the color sorter works, namely optical imaging and nozzles. The main function of optical imaging is to identify materials, and the nozzle is mainly to remove materials on the basis of identification. Inside the whole machine, there is a distance of about 10cm between the optical imaging point and the nozzle position, so the material needs a fixed delay and a stable running track from the position where the material is found to the position of the nozzle. The material jumps up and down on the chute machine, which causes the material to not run on the chute at a uniform speed. If the speed is inconsistent, the nozzle delay is also inconsistent, which will cause the nozzle to move in advance or delay, and ultimately lead to the decline of the color selection accuracy.

In addition, the up and down movement of the material actually affects the distance between the material and the optical imaging lens, resulting in blurred imaging, and also affects the distance between the material and the nozzle. Therefore, when the material is too far from the nozzle, the force of the nozzle on the material will be weakened, thereby reducing the color selection accuracy. 2. What is a crawler color sorter?

The crawler color sorter is to transport the materials to the sorting area by the conveyor of the crawler. During this process, the materials run at a constant speed and are relatively static, which can well maintain a fixed delay and a stable running track. This ensures the accuracy of color selection to the greatest extent.

When the chute color sorter is running, the material is continuously accelerated from top to bottom. Even if the color sorting is completed, the material will still be accelerated for a period of time and distance, which will increase the damage to the material and result in a high rate of damage. However, the crawler color sorter does not have this defect. The material moves horizontally on the crawler and falls flat. The material does not have the problem of excessive acceleration, and the damage to the material is relatively minor and the damage is small. For materials that require high breakage rates such as peanuts, peanuts, peeled peanuts, garlic, tea, etc., Zhongrui Microvision's crawler color sorter has been verified on site by customers, and the effect is significant and the damage rate is very low.

3. Analysis of the scope of application of chute color sorter and crawler color sorter

In contrast, the chute color sorter, because the channel is designed according to the shape and size of the product, it is suitable for regular materials such as rice and wheat. For materials with large differences in shape and size, such as peanuts, plastics, ore, and tea, the color The selection effect is not ideal. With the continuous enrichment of the types of materials on the market and the continuous improvement of color sorting requirements, the chute color sorting machine has gradually not adapted to the development trend of the color sorting industry.

This is not the case for crawler color sorters, which are suitable for color sorting of various materials. In terms of color sorting output, the speed of the crawler color sorting machine is controllable and the output can be adjusted. The design is specifically based on the actual production of the customer. The chute color sorter has a fixed structure, a fixed speed, and a fixed output.

Compared with the chute machine, the crawler color sorter requires some moving parts and the structure is relatively complicated, so the cost is relatively high. However, in a comprehensive comparison, the economic benefits of the crawler color sorter are still far greater than the cost. 4. Choose plastic, which is better for color sorter with crawler type or chute type?

Therefore, compared with the chute color sorter, the crawler color sorter has the advantages of a wide range of optional materials, high color sorting accuracy, small damage, high output, and small carry-out ratio. All in all, the cost performance of the crawler color sorter is higher than that of the traditional chute color sorter. The ability to use mechanization to select high-quality products has promoted the sustainable development of the plastics industry and played a role in protecting the environment.
