Description

Technical Field

[0001] The invention relates to the technical field of red date grading, and in particular to a red date conveying roller belt. Background Art

[0002] The intelligent sorting machine for red dates is an automated equipment designed for sorting, categorizing and processing red dates. With the increase in market demand for red dates, the traditional manual sorting method can no longer meet the high-efficiency and high-precision production requirements. The intelligent sorting machine for red dates uses advanced technical means to achieve fast and accurate sorting of red dates, greatly improving production efficiency and product quality. The placement of red dates on the conveyor roller belt in the intelligent sorting machine for red dates has a significant impact on the accuracy and efficiency of detection. If the red dates are placed at irregular angles, it may affect the recognition effect of the image recognition system. The sensor may not be able to obtain the complete characteristics of the red dates, resulting in inaccurate classification, and impurities on the surface of the red dates may also affect the recognition of the detection system. Summary of the invention

[0003] The purpose of the present invention is to provide a red date conveying roller belt, which has the effect of improving the efficiency of red date identification and sorting.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: a red date conveyor roller belt, including a frame and a visual detection device installed on the frame, sprockets are rotatably connected at both ends of the frame, and a chain located below the visual detection device is sleeved between the sprockets at both ends, and the chain has conveying rollers rotating equidistantly along its conveying direction, and the frame is fixedly installed with a nozzle located above the conveying roller. The frame is located below the conveying roller and is sequentially provided with a clearing component and a cleaning component along the conveying direction of the chain, the clearing component includes a plurality of movable rods that are repeatedly raised and lowered and arranged between adjacent conveying rollers, and the cleaning component includes a plurality of cleaning brushes whose ends are in contact with the conveying rollers.

[0005] By adopting the above technical scheme, the red dates are located on the conveyor roller, and the chain drives the conveyor roller and the red dates to be transported forward. During this period, the air jet blows off the impurities on the surface of the red dates, making the appearance characteristics of the red dates clearer, which helps the identification system to more accurately judge the quality of the red dates. The movable rod is raised and lowered between adjacent conveyor rollers to remove the red dates blocked between the conveyor rollers, which is beneficial to the position adjustment of the red dates and avoids affecting the identification work. At the same time, the conveyor roller can be flexibly rotated to adjust the position of the red dates under the push of the cleaning brush. When the cleaning brush pushes the conveyor roller, the transmission roller is cleaned synchronously. Finally, the red dates are adjusted to be parallel to the axial direction of the conveyor roller and enter the visual detection device for identification.

[0006] The present invention is further configured as follows: the conveying roller is configured to be wide at both ends and narrow in the middle, and the surface of the conveying roller is uniformly provided with protrusions along its axial direction.

[0007] By adopting the above technical scheme, the conveying path of red dates can be optimized and the jamming phenomenon can be reduced. The protrusions on the surface of the conveying roller make it easier for the cleaning brush in contact with it to push the conveying roller to rotate, thereby adjusting the detection position of red dates. The conveying roller is wide at both ends and narrow in the middle, which is beneficial to increasing the contact area between the red dates and the conveying roller, thereby improving the gripping force and improving the conveying stability.

[0008] The present invention is further configured as follows: a connecting plate located in the middle of the upper and lower chains is fixed between the inner walls on both sides of the frame, and a trough body is fixed on the connecting plate.

[0009] By adopting the above technical solution, impurities on the red dates blown off by the air jet head and impurities on the conveyor roller removed by the cleaning brush are collected in the trough body, which is convenient for the staff to clean up later and avoids pollution to the working environment.

[0010] The present invention is further configured as follows: the blocking assembly includes a first fixed plate fixed to the connecting plate, a first incomplete gear rotatably connected to the first fixed plate, and a second incomplete gear rotatably connected to the first fixed plate and meshed with the first incomplete gear, a first rack meshed with the first incomplete gear and the second incomplete gear is vertically slid on the first fixed plate, a mounting plate is fixed to the end of the first rack, and the movable rod is fixed to the mounting plate.

[0011] By adopting the above technical solution, the first incomplete gear and the second incomplete gear rotate to drive the first rack to slide vertically along the first fixed plate, so that the first rack drives the mounting plate and the movable rod to rise and fall. The lifting of the movable rod may poke out the red dates that are blocked between the conveying rollers, which is beneficial to the subsequent position adjustment of the red dates and the rotation of the conveying rollers.

[0012] The present invention is further configured as follows: the cleaning assembly includes a second fixed plate fixed to the connecting plate, a third incomplete gear rotatably connected to the second fixed plate, and a fourth incomplete gear rotatably connected to the second fixed plate and meshed with the third incomplete gear, a second rack meshed with the third incomplete gear and the fourth incomplete gear is horizontally slid on the second fixed plate, a mounting frame is fixed to the end of the second rack, and the cleaning brush is fixed on the mounting frame.

[0013] By adopting the above technical solution, the third incomplete gear and the fourth incomplete gear rotate to drive the second rack to slide back and forth, so that the second rack drives the mounting frame and the cleaning brush to slide back and forth to clean the conveying roller. At the same time, the conveying roller contacts and rotates with the cleaning brush to adjust the placement of the red dates, thereby improving the accuracy of the identification work.

[0014] The present invention is further configured as follows: the first incomplete gear and the third incomplete gear are both provided with symmetrical teeth, and the second incomplete gear and the fourth incomplete gear are both provided with lateral teeth.

[0015] By adopting the above technical solution, when the third incomplete gear rotates, the one-side symmetrical tooth first meshes with the second rack to drive the second rack to slide to one side, and the fourth incomplete gear rotates under the sliding of the second rack. When the one-side symmetrical tooth rotates away and no longer meshes with the second rack, the other-side symmetrical tooth meshes with the lateral tooth on the fourth incomplete gear to drive the fourth incomplete gear to rotate in the opposite direction. At the same time, the fourth incomplete gear meshes with the second rack to drive the second rack to slide in the opposite direction. After the one-side symmetrical tooth leaves the lateral tooth, it meshes with the second rack again to drive the second rack to slide in the initial direction, and so on and so forth, so as to realize the reciprocating forward and backward movement of the second rack, the cleaning conveying roller and the conveying roller are driven to rotate at the same time; the driving relationship between the first incomplete gear, the second incomplete gear and the first rack is the same as the above, thereby driving the first rack, the mounting plate and the movable rod to rise and fall reciprocally, and poking out the red dates blocked between the conveying rollers.

[0016] The present invention is further configured as follows: the mounting frame is provided with a through hole between adjacent cleaning brushes; the cleaning brush comprises a brush plate and bristles; the brush plate is configured in a triangular shape; and the bristles are fixed to the inclined surfaces on both sides of the brush plate.

[0017] By adopting the above technical solution, the cleaning brush can make the impurities scraped off the conveying roller pass through the through hole through the inclined surface and drop into the tank body, thereby reducing the accumulation of impurities on the cleaning brush and maintaining the cleaning effect.

[0018] The present invention is further configured as follows: a guide surface inclined toward the trough body is provided above the second rack.

[0019] By adopting the above technical solution, impurities on the second rack fall into the tank body, further maintaining the cleaning effect.

[0020] The present invention is further configured as follows: a transmission shaft rotating on the first fixed plate and the second fixed plate is fixed between the first incomplete gear and the third incomplete gear, and the transmission shaft is driven to rotate by a motor installed on the second fixed plate.

[0021] By adopting the above technical solution, the motor drives the transmission shaft to rotate and then drives the first incomplete gear and the third incomplete gear to rotate synchronously, thereby synchronously driving the cleaning brush to move back and forth and the movable rod to rise and fall repeatedly, thereby reducing the overall space occupied by the equipment, simplifying the design, and facilitating installation and maintenance.

[0022] The present invention is further configured as follows: limiting strips are fixed on both sides of the first rack and the second rack, and limiting grooves are provided on the first fixing plate and the second fixing plate for the limiting strips to slide.

[0023] By adopting the above technical solution, the first rack and the second rack can slide stably relative to the first fixed plate and the second fixed plate respectively, thereby improving the structural stability.

[0024] The beneficial effects of the present invention are:

[0025] 1. The red dates are placed on the conveyor roller, and the chain drives the conveyor roller and the red dates forward. During this period, the jet head blows off the impurities on the surface of the red dates, making the appearance characteristics of the red dates clearer, which helps the recognition system to judge the quality of the red dates more accurately;

[0026] 2. The movable rod is raised and lowered between adjacent conveyor rollers to remove the red dates stuck between the conveyor rollers, which is beneficial to the position adjustment of the red dates and avoids affecting the identification work;

[0027] 3. The conveyor roller can flexibly rotate and adjust the position of the red dates under the push of the cleaning brush. When the cleaning brush pushes the conveyor roller, it cleans the transmission roller synchronously, and finally the red dates are adjusted to be parallel to the axis of the conveyor roller, and enter the visual inspection device for identification, thereby improving the accuracy of identification;

[0028] 4. The impurities on the red dates blown off by the jet head and the impurities on the conveyor roller removed by the cleaning brush are collected in the tank body, which is convenient for the staff to clean up later and avoids pollution to the working environment;

[0029] 5. The cleaning brush scrapes the impurities from the conveyor roller through the inclined surface and drops them into the tank body through the through hole, reducing the accumulation of impurities on the cleaning brush and maintaining the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS
