Description

Technical Field

[0001] The present invention relates to the technical field of sorting and feeding, and in particular to a multi-channel vibrating feeding device for an optical sorter. Background Art

[0002] In the field of material sorting, especially in equipment based on optical sorting technology, the uniformity and sorting accuracy of the vibrating feeder directly affect the final sorting effect. Traditional vibrating feeders typically use a single vibrating screen structure, which disperses and conveys the material by adjusting the vibration frequency or amplitude.

[0003] However, when processing mixed particles with large density differences (such as lightweight plastic fragments and heavy metal particles), the weight of particles with different densities does not completely match the particle size. For example, even if metal particles are smaller than plastic particles, they are heavier than plastic particles. Existing screening can only rely on particle size for sieve-type sorting, which cannot accurately sort different materials well, thereby affecting the recognition accuracy of subsequent optical sensors and reducing sorting efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a multi-channel vibrating feeding device for an optical sorter, which has the advantages of achieving efficient and accurate sorting of materials through the dual vibration synergy of the vibrating screen plate and the vibrating sorting plate, combined with the mechanical sorting of the rotating oblique beating plate, and utilizing the natural bounce height difference between light particles and heavy particles during the vibration process to complete the sorting in the sense of weight.

[0005] To achieve the above object, the present invention provides the following technical solution: a multi-channel vibrating feeding device for an optical sorter, comprising a vibrating screen plate, a vibrator being provided on the vibrating screen plate, a vibrating sorting plate being mounted above the vibrating screen plate, and a sorting assembly being provided above the vibrating screen plate;

[0009] Furthermore, the sorting component also includes a mounting bracket, which is not connected to the vibrating screen plate, and one end of the rotating rod is connected to a driver installed on the mounting bracket.

[0017] The technical effects and advantages of the present invention are as follows:

[0018] 1. The present invention realizes efficient and accurate sorting of materials through the dual vibration synergy of the vibrating screen plate and the vibrating sorting plate, combined with the mechanical sorting of the rotating oblique beating plate. The natural bounce height difference between light particles and heavy particles during the vibration process is utilized to complete the sorting in the weight sense. Sorting can be achieved according to the material of the particles. The light and heavy particles after sorting enter different channels respectively, creating good pretreatment conditions for subsequent optical sorting or other processing steps, significantly improving the accuracy and processing efficiency of the overall sorting system, and being suitable for sorting operations of large quantities of mixed materials.

[0019] 2. The present invention is provided with a screed plate before sorting. The screed plate can move up and down to adapt to the size of the particles to be fed.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] In order to better understand the multi-channel vibrating feeding device of an optical sorter provided in this embodiment, the existing vibrating feeding equipment is briefly introduced below. The existing technology can only sort materials of different sizes through filter holes, and the sorting efficiency of light particles is low, which easily causes material mixing. The embodiment of the present application provides a multi-channel vibrating feeding device for an optical sorter. Through the dual vibration synergy of the vibrating screen plate 1 and the vibrating sorting plate 2, combined with the mechanical sorting of the rotating oblique beating plate 32, efficient and accurate sorting of materials is achieved. The natural bounce height difference between light particles and heavy particles during the vibration process is utilized, and automatic sorting can be achieved without additional energy input, with significant energy-saving effect.

[0036] Example 1: Reference Figure 1 - Figure 3, which is the first embodiment of the present invention, provides a multi-channel vibrating feeding device for an optical sorter, including a vibrating screen plate 1, wherein the vibrating screen plate 1 is equipped with a vibrator. In this embodiment, the vibrator is used to drive the vibrating screen plate 1 and the vibrating sorting plate 2 to vibrate at the same frequency, and this solution also provides another way, that is, the vibrating sorting plate 2 and the vibrating screen plate 1 use different vibrators, so that the vibration frequency of the vibrating sorting plate 2 is independent of the vibrating screen plate 1, so as to achieve graded vibration feeding, a vibrating sorting plate 2 is mounted above the vibrating screen plate 1, and a sorting component 3 is arranged above the vibrating screen plate 1, and the sorting component 3 includes a rotating rod 31 and a plurality of oblique beating plates 32 arranged in a ring array on the surface of the rotating rod 31, and the rotating rod 31 rotates counterclockwise to drive the oblique beating plates 32 to rotate, and the vibrating screen plate 1 is used for material vibration bouncing, and the light-weight particles bounce height is higher than The particles with large weight and light particles bounce higher than the vibration sorting plate 2, and the rotating oblique beating plate 32 is used to sort the particles that bounce higher than the vibration sorting plate 2 onto the vibration sorting plate 2 for classified vibration feeding. When the bounce height of the light particles exceeds the vibration sorting plate 2, the dual vibration synergy of the vibrating screen plate 1 and the vibration sorting plate 2, combined with the mechanical sorting of the rotating oblique beating plate 32, achieves efficient and accurate sorting of the materials. The natural bounce height difference between light particles and heavy particles during the vibration process is utilized to complete the sorting in the sense of weight, and the sorting can be achieved according to the material of the particles. The light and heavy particles after sorting enter different channels respectively, which creates good pretreatment conditions for subsequent optical sorting or other processing steps, significantly improving the accuracy and processing efficiency of the overall sorting system, and is suitable for sorting large quantities of mixed materials.

[0037] Specifically, the rotating rod 31 rotates counterclockwise, driving the oblique beating plate 32 to rotate to beat the materials that bounce to a certain height, and beat them onto the vibrating sorting plate 2, thereby completing the screening of light-weight materials.

[0038] The vibrating screen plate 1 is also equipped with a screed plate 11 that can move up and down. The distance between the screed plate 11 and the vibrating screen plate 1 is adapted to the size of the material particles, and the sorting component 3 is arranged between the screed plate 11 and the vibrating sorting plate 2. It should be noted that in the actual discharge process, the material is prone to accumulation and vibration. In the process of vibrating feeding, the accumulation of materials will systematically change the movement trajectory of the particles, the collision frequency between particles of different weights will increase, and a force chain network will be formed, resulting in nonlinear energy transfer. The light particles are significantly "shielded" by the heavy particles, and the light particles are trapped between the heavy particles. "Pseudo-agglomerates" are formed in the gap, resulting in the attenuation of the effective vibration intensity of the upper particles and the complete loss of independent mobility of the light particles. In order to avoid the above situation, this solution is equipped with a leveling plate 11 before sorting. The leveling plate 11 can move up and down to adapt to the size of the particles to be fed. When the material thickness exceeds the distance between the leveling plate 11 and the vibrating screen plate 1 during the vibration process, it will be blocked by the leveling plate 11 to ensure that the material moved between the vibrating sorting plates 2 is within a uniform thickness range, without affecting the bouncing mobility of the light particles under vibration, so that it can better achieve initial sorting.

[0039] The sorting component 3 also includes a mounting bracket 33, which is not docked with the vibrating screen plate 1. One end of the rotating rod 31 is connected to a driver mounted on the mounting bracket 33. A slot for the rotating rod 31 to penetrate is provided on the vibrating sorting plate 2, and the slot diameter is larger than the diameter of the rotating rod 31. When the vibrating sorting plate 2 vibrates, the vibration will not be transmitted to the rotating rod 31, and long-term vibration conduction will not cause damage to the rotating rod 31 and the oblique hitting plate 32 structure, thereby improving the service life of the sorting structure.

[0040] The vibrating sorting plate 2 and the vibrating screen plate 1 feeding sections are staggered, and a dividing plate 21 is provided below the vibrating sorting plate 2 and the vibrating screen plate 1 feeding sections, and the dividing plate 21 below the vibrating sorting plate 2 is arranged side by side with the vibrating screen plate 1 feeding section. Sieve holes are provided on the vibrating sorting plate 2 and the vibrating screen plate 1 feeding sections, and the sorting component 3 is used for preliminary sorting. However, it should be noted that there are also a small number of smaller metal particles. When the smaller metal particles vibrate, they will also generate high bouncing force and will be sorted onto the vibrating sorting plate 2 along with the large and light plastic materials. In this scheme, sieve holes are provided on the vibrating sorting plate 2 to discharge the small metal particles into another channel, and sieve holes are also provided on the vibrating screen plate 1 to achieve multi-level and multi-channel feeding of different materials.

[0041] Example 2: Reference Figure 4 - Figure 6, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the oblique beating plate 32 is docked with the outer wall of the rotating rod 31 through the bearing member 321. The inclination angle of the oblique beating plate 32 is adjustable to adapt to the bouncing characteristics of different materials, and an adjustment component 4 is provided inside the rotating rod 31 to drive the oblique beating plate 32 to tilt. The adjustment component 4 includes an outer rotating ring 41 that drives the bearing member 321 to rotate. The outer wall of the outer rotating ring 41 is connected to the bearing member 321 through a gear. The outer rotating ring 41 is docked with the driving member. In order to adjust Materials of different particle sizes and densities can be sorted by adjusting the inclination of the inclined beating plate 32 so that when it contacts the bouncing particles, it can contact the particles at a relatively vertical angle, and the direction of the inclined beating plate 32 is from bottom to top. The adjustment of the contact angle makes it easier for the inclined beating plate 32 to lift the particles upward, making it convenient for them to be sorted onto the vibrating sorting plate 2. The rotation angle and speed of the inclined beating plate 32 are adjustable, which can adapt to the sorting needs of materials of different particle sizes and densities, and has strong versatility and adaptability.

[0042] Specifically, the driving member drives the outer rotating ring 41 to rotate, and the outer rotating ring 41 drives multiple bearing members 321 and the oblique hitting plate 32 to rotate synchronously to adjust the inclination angle through gears, and the adjustment component 4 is set on the rotating rod 31, which can independently drive the oblique hitting plate 32 to rotate and adjust the angle without affecting the rotating rod 31 to drive multiple oblique hitting plates 32 to revolve.

[0043] Example 3: Reference Figure 7 - Figure 9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment. During the implementation process, it was found that when the material receiving end of the vibrating screen plate 1 is receiving the material, the material is mostly accumulated in the middle when it is unloaded. During the vibration process, the material is accumulated in the middle, while there is too little material on both sides, resulting in uneven distribution of materials in the same channel, and there is local accumulation or sparseness.

[0044] In order to solve the above problems, this embodiment provides an annular shell 331 on the inner wall of the mounting bracket 33, and a turbine blade 332 is provided in the annular shell 331. The turbine blade 332 is sleeved on the rotating rod 31, and one end of the material leveling plate 11 is connected to the support plate 111. The nozzle 112 is vertically provided on the support plate 111. The air outlet end of the annular shell 331 is connected to the nozzle 112 through an air pipe. During the rotation of the rotating rod 31, the rotation of the rotating rod 31 drives the turbine blade 332 to rotate, and the airflow generated in the annular shell 331 is transported to the nozzle 112 through the pipeline. The nozzle 112 blows the material accumulated in the middle of one end of the material leveling plate 11 to both sides, effectively solving the problem of local accumulation or sparseness, making the material in the same channel evenly distributed, and utilizing the power of sorting to achieve material uniformity, effectively saving driving costs.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
