Description

Technical Field

[0001] This invention specifically relates to a dual-rejection color sorting mechanism and method. Background Technology

[0002] In material color sorting, high-pressure airflow is usually blown through nozzles to remove defective products. However, when sorting large oval materials such as potatoes, due to the large differences in shape and size, the traditional nozzle rejection structure is not effective for materials larger than 120mm and it is difficult to push away defective products for rejection. Therefore, we propose a dual rejection color sorting mechanism and method. Summary of the Invention

[0003] The purpose of this invention is to provide a dual-rejection color sorting mechanism and method to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a dual-rejection color sorting mechanism, comprising:

[0005] A nozzle assembly for blowing small-volume materials;

[0006] The mounting block is located below the mouthpiece assembly;

[0007] A lever is rotatably mounted on one side of the mounting block to move large volumes of material away, and there is a drive assembly between the mounting block and the lever to drive the lever to rotate.

[0008] Connecting blocks are disposed at both ends of the mounting block to fix them to the inner cavity of the color sorter.

[0009] Preferably, the drive assembly includes a first upright plate, a second upright plate, and a shift finger. The first upright plate and the second upright plate are arranged side by side inside the mounting block, and a telescopic cylinder is rotatably connected to the lower end of the first upright plate. One end of the shift finger is rotatably engaged with the second upright plate, and one end of the telescopic cylinder is rotatably connected to the shift finger.

[0010] Preferably, the upper end of one side of the first upright plate is provided with bolts for fixing to the mounting block.

[0011] Preferably, the mounting block has a through hole for inserting a flexible hose, and the through hole corresponds to the telescopic cylinder along the height direction.

[0012] Preferably, the shift finger includes a base plate and a shift block, the shift block is fixed to the base plate, and the cross-section of the shift block is "D" shaped.

[0013] Preferably, the base plate and the lever are both made of high molecular polymer.

[0014] Preferably, multiple shift fingers are evenly distributed along the long side of the mounting block, and the number of drive components is equal to that of the shift fingers.

[0015] Preferably, the mouthpiece assembly is flush with the end of the mounting block, and the mouthpiece assembly is provided with brackets at both ends.

[0016] A method for a dual-rejection color sorting mechanism includes the following steps:

[0017] Step A: The material is conveyed by the transmission component of the color sorter. The size of the material is identified by the camera of the color sorter. According to the size, the rejection signal is selectively transmitted to the nozzle component or the valve body that controls the movement of the telescopic cylinder. At the same time, the material is thrown out at one end of the transmission component.

[0018] Step B: When the material is in a small volume, the nozzle assembly receives a rejection signal, blows out high-pressure gas, and the gas pushes the material away.

[0019] Step C: When the material is large in volume, after the valve body receives the signal, the telescopic cylinder extends to push the lever to rotate around the lower end of the second vertical plate. One end of the lever rotates upward to contact the material and push the material to remove it.

[0020] Step D: Good materials fall to the good product outlet under the action of gravity and inertia, while materials pushed by the nozzle assembly or the finger fall to the defective product outlet, thus completing the sorting process.

[0021] Preferably, in step A, a length dimension of 120mm is used as a boundary to distinguish between small-volume and large-volume materials.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention facilitates the effective removal of large-volume materials, avoiding the limitations of traditional methods that rely solely on high-pressure airflow, which struggles to push materials during the ejection process. This device can be effectively combined with a nozzle to remove small and large-volume materials separately as needed, effectively ensuring the accuracy of removal. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-5 The present invention provides a technical solution: a dual-rejection color sorting mechanism, comprising:

[0032] A nozzle assembly 1 for blowing small-volume materials;

[0033] Mounting block 2 is located below mouthpiece assembly 1;

[0034] The finger 4 is rotatably mounted on one side of the mounting block 2 to move large volume materials away, and there is a drive assembly 3 between the mounting block 2 and the finger 4 to drive the finger 4 to rotate.

[0035] To facilitate the removal of large-volume materials after they are identified by the color sorter, the material is pushed away by the contact of the finger 4, which reduces the difficulty of airflow in pushing large-volume materials and thus reduces the low color sorting accuracy. In this invention, the dividing line between large-volume materials and small-volume materials is 120mm in length.

[0036] Connecting block 5 is located at both ends of mounting block 2 to be fixed to the inner cavity of the color sorter;

[0037] This facilitates quick and easy installation of the four-finger switch.

[0038] Preferably, the drive assembly 3 includes a first upright plate 31, a second upright plate 33 and a shift finger 4. The first upright plate 31 and the second upright plate 33 are arranged side by side inside the mounting block 2, and the lower end of the first upright plate 31 is rotatably connected to a telescopic cylinder 32. One end of the shift finger 4 is rotatably engaged with the second upright plate 33, and one end of the telescopic cylinder 32 is rotatably connected to the shift finger 4.

[0039] The telescopic cylinder 32 is used to drive the finger 4 to rotate, so that the finger 4 can come into contact with the material to remove defective products. The telescopic cylinder 32 is a pneumatic cylinder or an electric cylinder.

[0040] Preferably, a bolt for fixing to the mounting block 2 is provided at the upper end of one side of the first upright plate 31;

[0041] It is easy to connect and fix, and also easy to disassemble and maintain later.

[0042] Preferably, the mounting block 2 has a through hole 34 for inserting a flexible hose, and the through hole 34 corresponds to the telescopic cylinder 32 along the height direction;

[0043] This allows the air tube or cable to pass through the through hole 34 for connection with the telescopic cylinder 32.

[0044] Preferably, the lever 4 includes a base plate 41 and a lever block 42, the lever block 42 is fixed on the base plate 41, and the cross section of the lever block 42 is "D" shaped;

[0045] The "D" shape allows for slight deformation of the shift finger 4, which creates a buffer when in contact with the material, reducing the damage caused by large rigid collisions.

[0046] Preferably, the base plate 41 and the lever block 42 are both made of high molecular polymer.

[0047] This facilitates better corrosion resistance and strength.

[0048] Preferably, multiple shift fingers 4 are evenly distributed along the long side of the mounting block 2, and the number of drive components 3 is equal to the number of shift fingers 4;

[0049] It facilitates the simultaneous rejection of multiple materials.

[0050] Preferably, the mouthpiece assembly 1 is flush with the end of the mounting block 2, and the mouthpiece assembly 1 is provided with brackets 11 at both ends.

[0051] A method for a dual-rejection color sorting mechanism includes the following steps:

[0052] Step A: The material is conveyed by the transmission component of the color sorter. The size of the material is identified by the camera of the color sorter. According to the size, the rejection signal is selectively transmitted to the nozzle assembly 1 or the valve body that controls the movement of the telescopic cylinder 32. At the same time, the material is thrown out at one end of the transmission component.

[0053] Step B: When the material is in a small volume, the nozzle assembly 1 receives a rejection signal, and the nozzle assembly 1 blows out high-pressure gas, which pushes the material.

[0054] Step C: When the material is large in volume, after the valve body receives the signal, the telescopic cylinder 32 extends to push the finger 4 to rotate around the lower end of the second vertical plate 33. One end of the finger 4 rotates upward to contact the material and push the material to remove it.

[0055] Step D: Good materials fall to the good product outlet under the action of gravity and inertia, while materials pushed by the nozzle assembly 1 or the finger 4 fall to the defective product outlet, thus completing the sorting.

[0056] Preferably, in step A, a length dimension of 120mm is used as a boundary to distinguish between small-volume and large-volume materials.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
