Description

A color sorter Technical Field

[0001] This utility model relates to the field of color sorter technology, and specifically to a color sorter. Background Technology

[0002] A color sorter is a device that automatically separates discolored particles from granular materials based on differences in their optical properties using photoelectric detection technology. Color sorters are commonly used in the sorting of fruits and vegetables. By tilting the fruits and vegetables from the collection frame, color sorting imaging captures the color of the fruits and vegetables during their descent. Then, with the help of external driving components, external force is applied directly or indirectly to the fruits and vegetables to achieve sorting.

[0003] Existing color sorters still have certain shortcomings in actual use. When fruits and vegetables are poured and fall freely, they may overlap, which can easily lead to missorting during subsequent sorting. This requires re-sorting and results in low efficiency. In view of this, we propose a new color sorter. Summary of the Invention

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example: Referring to Figures 1-4, a color sorter includes a mounting frame 100. A color sorting mechanism 110 is fixedly mounted on one side of the mounting frame 100. A rotating shaft 210 is provided on the mounting frame 100, and a conveyor belt 200 for conveying fruits and vegetables to be sorted is sleeved on the rotating shaft 210. Specifically, in this application, through the provided rotating shaft 210 and the conveyor belt 200 sleeved on the rotating shaft 210, the conveyor belt 200 can convey the fruits and vegetables to be sorted. The aforementioned color sorting mechanism 110 is prior art and is used to sort fruits and vegetables that fall from the end of the conveyor belt 200. The so-called color sorting mechanism 110 includes detecting the color of fruits and vegetables and then using pneumatic means to act on the fruits and vegetables for sorting.

[0033] In the aforementioned color sorting process, to ensure stable sorting of fruits and vegetables, this application involves flattening the fruits and vegetables on the conveyor belt 200. This ensures that the fruits and vegetables conveyed on the conveyor belt 200 remain in a single layer, thereby preventing overlap during subsequent color sorting and avoiding suboptimal sorting results. Specifically, in this application, one of the rotating shafts 210 has cams 220 fixedly connected to both ends, and a piston tube 340 fixedly connected to the mounting bracket 100. The piston tube 340 has a movable... The device includes a piston rod 341, the end of which extends through the piston tube 340 to the outside and slides into the vertical groove 311. It also includes a bladder 120 fixedly mounted on the side of the mounting bracket 100. An overlapping plate is fixedly mounted on one outer wall of the bladder 120. The outer wall of the cam 220 slides into the outer wall of the overlapping plate. When the rotating shaft 210 rotates, the outer wall of the cam 220 contacts the outer wall of the overlapping plate and squeezes the bladder 120. The interior of the bladder 120 is connected to the interior of the piston tube 340 through the connecting tube 342.

[0034] Specifically, in the actual color sorting process, when fruits and vegetables are placed on the conveyor belt 200, the corresponding rotating shaft 210 is in a rotating state, and the cam 220 fixedly connected to the end of the rotating shaft 210 will also rotate synchronously. When the cam 220 rotates, the bladder 120 located on one side of the mounting frame 100 will also be squeezed. When the bladder 120 is squeezed, the gas inside it will enter the piston tube 340, thereby driving the piston rod 341, which is movably connected to the piston tube 340, to move intermittently, thereby causing the moving plate 300 to move back and forth in a direction perpendicular to the conveyor belt 200.

[0035] Furthermore, it also includes a squeezing bladder 330 adhered to the lower outer wall of the moving plate 300. The squeezing bladder 330 is connected to the output end of an external air pump via a hose 320. When the moving plate 300 reciprocates in the horizontal direction, the corresponding squeezing bladder 330 will contact the outer wall of the fruits and vegetables, ensuring that the fruits and vegetables are stably transported by the conveyor belt 200 without accumulation, thus ensuring the accuracy of subsequent color sorting results.

[0036] Furthermore, this application also includes a movable plate 300 movably connected to the upper side of the mounting bracket 100, with connecting blocks 310 fixedly connected to both ends of the movable plate 300, and vertical grooves 311 formed on the connecting blocks 310; it also includes sliding grooves 101 formed on both sides of the mounting bracket 100, with multiple arc-shaped grooves 102 fixedly arranged inside the sliding grooves 101; arc-shaped blocks are fixedly installed on the outer walls of both ends of the movable plate 300, the arc-shaped blocks slide in engagement with the arc-shaped grooves 102, and the connecting blocks 310 slide in engagement with the sliding grooves 101. When gas enters the piston tube 340, it causes the piston rod 341 to shift. It should be noted that in this application, when the moving plate 300 moves horizontally, the arc-shaped block fixedly installed at the end of the moving plate 300 slides in the arc-shaped groove 102. Combined with the sliding cooperation between the two, the moving plate 300 not only moves back and forth in the horizontal direction, but also vibrates synchronously in the vertical direction. Through this vibration, the fruits and vegetables on the conveyor belt 200 can be squeezed, thereby ensuring that the fruits and vegetables present a stable, flat layer structure and are stably transported by the conveyor belt 200, avoiding the instability of color sorting results caused by the obstruction between different fruits and vegetables during the color sorting process.

[0037] Furthermore, in this application, the outer wall of the conveyor belt 200 is provided with a plurality of grooves 201, which are arranged in a linear structure in order to guide the fruits and vegetables during the conveying process and ensure their stable transmission.

[0038] Furthermore, to prevent green leaves and other structures adhering to the fruits and vegetables during transportation from affecting subsequent color sorting results, this application also includes a fixed frame 400 movably connected to the lower side of the mounting frame 100. An overlapping shaft 410 is rotatably connected to the fixed frame 400, and the fixed frame 400 remains connected to the output end of an external hydraulic cylinder. By controlling the external hydraulic cylinder, the overlapping shaft 410 can be intermittently driven to contact the outer wall of the conveyor belt 200, thereby causing the conveyor belt 200 to vibrate. This ensures the stability of fruit and vegetable condition adjustment and also cleans away impurities such as green leaves left on the surface of the conveyor belt 200 during transportation.

[0039] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
