Description

Technical Field

[0001] The invention relates to the technical field of color sorters, in particular to a material hanging prevention hopper device for a color sorter. Background Art

[0002] In the prior art, the receiving hopper of the color sorter is generally separated by a partition plate. The color sorter throws the sorted finished materials and unqualified materials to the two sides of the partition plate respectively to achieve the purpose of separating good and bad materials. In the actual sorting process, some materials are easy to hook on the upper plate edge of the partition plate, especially when sorting materials that are easy to bend or have handles, such as pickled peppers, edamame clips, dried chili peppers with handles, etc. In particular, in the sorting of dried chili peppers, dried chili peppers with straight rods are qualified products, and dried chili peppers with curved hook-shaped rods are defective products. Dried chili peppers with curved hook-shaped rods are very easy to hang on the upper plate edge of the partition plate. As the number of materials hooked on the partition plate increases, the sorting effect of the materials will be seriously affected, and the color sorter needs to be stopped for cleaning. Manual cleaning is not only very troublesome, but also increases the labor intensity of workers, and affects the normal sorting work of the color sorter. Summary of the invention

[0019] Combined with Figure 1-4 , the specific implementation mode of the present invention is described as follows:

[0020] like Figure 1 , 2As shown in Figures 3 and 4, a material receiving hopper device for color sorting machine to prevent hanging materials includes a receiving hopper body 1 arranged at the front side of the end of a conveyor belt 100, a hinged partition plate 2 is installed in the receiving hopper body 1, and the interior of the receiving hopper body 1 is divided into a qualified product hopper 11 located at the front side and a defective product hopper 12 located at the rear side by the partition plate 2. The finished materials and unqualified materials thrown out from the end of the conveyor belt 100 fall into the qualified product hopper 11 and the defective product hopper 12 respectively through the partition plate 2. The movement parabola 101 of the materials is as shown in Figure 101. Figure 1 , Figure 2 as shown in .

[0021] The lower end of the partition plate 2 is hinged at the connection between the qualified product hopper 11 and the defective product hopper 12 in the hopper body 1. The partition plate 2 is controlled by the partition plate adjustment device 3 and rotates with its hinge point as the center. By adjusting the rotation angle of the partition plate 2, the size of the qualified product hopper 11 and the defective product hopper 12 is adjusted, thereby adjusting the degree of sorting of qualified products and defective products in the material. At the same time, the rotation angle adjustment of the partition plate 2 can also adjust the probability of material hanging on the upper plate of the partition plate to a certain extent.

[0022] The partition adjustment device 3 includes an arc-shaped adjustment plate 31, an adjustment stud 32, a locking nut 33 and an arc-shaped adjustment hole 34. The arc-shaped adjustment plate 31 is installed on the side end surface of the partition plate 2, and the arc-shaped adjustment hole 34 is installed on the side end surface of the receiving hopper body 1. The adjustment stud 32 is arranged through the arc-shaped adjustment hole 34, and its inner end is fixed on the arc-shaped adjustment plate 31. The locking nut 33 is installed on the outer end of the adjustment stud 32 through a threaded connection.

[0023] The arc-shaped adjustment plate 31 is perpendicular to the partition plate 2 and parallel to the side end surface of the receiving hopper body 1. The adjusting stud 32 is provided with an external thread, and the inner wall of the locking nut 33 is provided with an internal thread, and the external thread is adapted to the external thread. The locking nut 33 is screwed in or out on the adjusting stud 32 to achieve compression and separation from the side end surface of the receiving hopper body 1, thereby achieving adjustment and fixed locking of the rotation position of the partition plate 2.

[0024] A round roller 4 is arranged on the top surface of the partition plate 2, and a pneumatic motor 5 is installed at one end of the round roller 4. A bearing seat 41 is installed at the other end of the round roller 4. The pneumatic motor 5 and the bearing seat 41 are respectively installed at the left and right ends of the top surface of the partition plate 2. The electromagnetic valve 7 is connected to the pneumatic motor 5 through the air pipe 6. The round roller 4 is controlled to rotate by the pneumatic motor 5, and the pneumatic motor 5 is controlled to open and close by the electromagnetic valve 7 and the air pipe 6. The arrangement of the round roller 4 on the upper plate of the partition plate 2 can make it difficult for the bent or handle materials that would originally hang on the upper plate to hang on the round roller 4 and fall into the qualified product hopper 11 or the defective product hopper 12; at the same time, even if a small amount of bent or handle materials hang on the round roller 4, the round roller 4 can be controlled to rotate by the pneumatic motor 5, so that the bent or handle materials hanging on the round roller 4 can fall into the qualified product hopper 11 or the defective product hopper 12.

[0025] A plurality of raised ridges 42 are arranged on the outer wall of the round roller 4. If the round roller 4 is arranged to have a smooth outer circumference, once the bent or handle material is hung on the round roller 4, even if the round roller 4 is rotated under the control of the pneumatic motor 5, there may be a very small amount of the bent or handle material and the smooth outer circumference of the round roller 4, which may not fall. The arrangement of the raised ridges 42 can increase the friction between the outer circumference of the round roller 4 and the bent or handle material. When the round roller 4 rotates, the bent or handle material hung on the round roller 4 is more likely to fall into the qualified product hopper 11 or the defective product hopper 12.

[0026] In addition, if the round roller 4 is rotated under the control of the pneumatic motor 5, there will still be a few bends or belts that hang or get stuck on the outer circumference of the round roller 4 without falling. At this time, the partition plate 2 can be controlled to rotate by the partition adjustment device 3, so as to shake it into the qualified product hopper 11 or the defective product hopper 12.

[0027] The present invention discloses a material hopper device for preventing material hanging for a color sorter. By installing a round roller 4 on the top of a partition plate 2, the probability of material hanging of bent or handled materials can be reduced. Meanwhile, the round roller 4 is controlled to rotate by an air motor 5, so that the bent or handled materials hanging on the round roller 4 can be automatically cleaned at a regular time.

[0028] The present invention discloses a material hopper device for preventing material hanging for a color sorter, which has a compact structure, effectively solves the problem of material hanging on the upper side plate of a partition plate, reduces the probability of material hanging, and realizes the timed automatic cleaning of material hanging on the partition plate, has good reliability, is easy to use, and saves time and effort.

[0029] The above is an exemplary description of the invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
