What is the difference between a belt color sorter and a slide-type optical sorter?
We know that there are mainly belt color sorters and slide-type color sorters on the market. Which of the two is more efficient and suitable? In the following, the color sorter manufacturer Growking Optoelectronic will explain this.
Compared with the traditional slide type color sorter, the belt color sorter has the advantages of high color sorting accuracy, small damage, high output, and direct packaging after selection. It is more and more widely recognized and accepted by color sorter customers, and its market share is also expanding.
1. Analysis of the application scope of the slide type color sorter and the belt color sorter
On the other hand, because the slideway of the slide-type color sorter is designed according to the shape and size of the product, it is suitable for regular materials such as rice and wheat. The selection effect is not ideal. With the continuous enrichment of material types in the market and the continuous improvement of color sorting requirements, the slideway color sorter has gradually not adapted to the development trend of the color sorting industry. The belt color sorter is not the case, it is suitable for color sorting of various materials.
2. What is the slide type color sorter?
The slide type color sorter uses gravity to make the material slide along the slide at high speed. Some materials cannot slide at a uniform 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, so the material needs a fixed delay and a stable running trajectory from the found position to the nozzle. The material jumps up and down on the slide machine, which causes the material to not run on the slide at a uniform speed. If the speed is inconsistent, the nozzle delay will also be inconsistent, which will cause the nozzle to move in advance or delay, which will eventually lead to the decline of color selection accuracy.
In addition, the up and down jump of the material actually affects the distance from the material to the optical imaging lens, resulting in blurred images. The up and down jump of the material will also affect the distance from the material to 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.
3. What is the belt color sorter?
The belt color sorter relies on the transmission of the belt to send the material to the sorting area. During this process, the material runs at a constant speed and is relatively static, which can well keep the delay fixed and the running track stable. This ensures the accuracy of color selection to the greatest extent.
When the slide type 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, resulting in a high breakage rate.
The belt color sorter does not have this defect. The material moves horizontally on the belt, and it flies and falls flat. The material does not have the problem of being over-accelerated, and the damage to the material is relatively minor and the damage is small. For peanuts, peanuts, peeled peanuts, garlic, tea and other materials that require a relatively high breakage rate, the Growking Optoelectronic belt color sorter has been verified by customers on-site, and the effect is remarkable and the breakage rate is very low.
In terms of color sorting output, the speed of the belt color sorting machine is controllable and the output can be adjusted, which is specifically designed according to the actual production of customers. The chute color sorter has a fixed structure, fixed speed and fixed output.
Compared with the slide machine, the belt color sorter needs some moving parts, and the structure is relatively complex, so the cost is relatively high. However, in a comprehensive comparison, the economic benefits of the belt color sorter are still far greater than the cost input.
4. Summary:
Compared with the chute color sorter, the belt color sorter has a wide range of optional materials, high color sorting accuracy, small damage, high output and small take-out ratio. In short, the cost-effectiveness of the belt color sorter is much higher than that of the traditional slide color sorter. It perfectly realizes the screening function, and can use mechanization to select high-quality products, which greatly promotes the development of agricultural mechanization. Instead of slide color sorter, it has become the first choice of color sorting customers.
