Description

Multi-track particle size classifier

The creative department belongs to a technical field of particle size classification, and specifically refers to a multi-track particle size classifier with high classification accuracy, thereby improving the classification efficiency of fruits and improving its practicability.

Press, when the fruit is sold, it will have different prices according to different size levels, so the selection of the grade is very important. Early round fruit-like fruits [such as lemon, willow, apple, etc.], if they are to be individually packaged according to the size of the fruit, are often treated as artificial. However, manual selection is labor intensive and the visual standards are different. In order to save time and improve efficiency, screening machine screening is used instead of manual screening. Currently, the fruit screening machine is divided into two types: a cylinder screen type and a roller belt type. Among them, the barrel screen type is a plurality of drums arranged in the machine table. A through hole having a predetermined aperture is opened in the periphery of each roller, so that the fruit smaller than the through hole can be dropped outside the roller to be received between the containers, and the fruit larger than the through hole remains in the roller and The end outlet can be opened at the end to be caught between the corresponding containers; if the sieve mechanism needs to be sized for more sizes, then more rolls can be assembled to achieve more presets. A particle screening results in an increase in the cost of grading, and it is easy to cause fruit damage during the screening process, so it can only be used to screen some fruits that are more resistant to abrasion.

As for the roller belt type, as shown in the first figure, it is attached to a frame. (10) is provided with a feeding portion (11) and a discharging portion (12) at both ends, and the frame (10) is provided with a plurality of brackets between the feeding portion (11) and the discharging portion (12) (13), further comprising a screening device (20) on the frame (10), the screening device (20) having a driving component (21) disposed on the frame (10) and two in the frame (10) The end is provided with a first transmission shaft (22), a second transmission shaft (23) and a plurality of turning shafts (24), and is connected to the first and second transmission shafts (22, 23) and the turning shaft (24). Providing at least two adjacent and radially arranged conveyor belts (25) for driving the driving elements (21) to drive the first transmission shafts (22) to actuate the conveyor belts (25) to rotate synchronously, and adjacent thereto A screening gap (26) having a width gradually widened from the feeding portion (11) to the discharging portion (12) is formed between the conveying belts (25). During operation, the fruit is rolled from the feeding part (11) onto the conveying belt (25) and conveyed under the driving of the conveying belt (25). The fruit is different in size and the screening gap between the conveying belts (25) (26) Fall into the corresponding bracket (13) below, so that the fruit can be divided into different levels according to the size of the head. However, since the conveyor belt (25) may be deformed due to pulling, aging, etc. after a long period of use, the width of the screening gap (26) is changed, which affects the accuracy of the picking, and manual adjustment is required to reduce the picking. Efficiency, while highlighting the shortcomings of the applicability of conventional particle size classifiers.

The reason is that the creator has in-depth discussion on the problems faced by the above-mentioned existing sorting equipment, and has been successfully developing multi-track particle size classifiers through years of research and development and manufacturing experience in related industries, through continuous efforts to improve and test. In order to overcome the inconvenience and trouble caused by the poor accuracy of the existing ones.

Therefore, the main purpose of this creation is to provide an accurate classification. The high-orbital orbital size classifier is designed to effectively classify the fruit size and increase its practicability.

Therefore, the main purpose of this creation is to provide an efficient multi-track particle size classifier that can reduce the number of re-picking, improve the classification speed, and improve its working efficiency.

Based on this, the author mainly implements the above-mentioned purposes and functions through the following technical means, which includes: a frame, which is provided with a feeding portion and a discharging portion at both ends, and the frame is advanced. A plurality of brackets are disposed between the material portion and the discharging portion; a screening device is disposed on the frame, the screening device is provided with a driving component on the frame, and the screening device is provided at one end of the frame a first sprocket shaft, a second sprocket shaft and a plurality of turning wheel shafts, wherein the first and second sprocket shafts and the turning wheel shaft are respectively provided with at least two chain plates, and the first and second sprocket shafts The equal turning wheel axle can be provided with at least two adjacent and radially arranged conveyor belts by using the corresponding chain ring, so that a width from the feeding portion to the discharging portion is respectively formed between the two adjacent conveyor belts. a gradually widening screening gap, wherein the conveyor belts are respectively composed of a chain and a plurality of adjacent chain links, wherein the chain can be looped on the first and second chain axles and the chain of the turning axles Outside the disk, the bracket of the rack is located within the range surrounded by the conveyor belt.

Thereby, through the specific implementation of the above technical means, the multi-track particle size classifier of the present invention can simultaneously process a plurality of objects such as fruits, so that different radial screening gaps between adjacent transmission belts of the screening device are used. The size of the sorting, and because the conveyor belt is composed of chain and chain blocks, the chain is limited by the position of the chain, and the chain blocks are not easy to be used for a long time. Pulling and aging changes, so it does not cause the change of the screening gap width, so the accuracy of the picking classification is high, without the need for manual sorting, greatly improving the efficiency of picking, thereby increasing the added value of the product and improving its economic benefits. .

In order to enable the reviewing committee to further understand the composition, features and other purposes of the present invention, the following is a preferred embodiment of the present invention, and the detailed description of the present invention is as follows, and the person skilled in the art can implement it.
