If it is determined to be unqualified, the leather is blown into the unqualified channel 14 through the exhaust of the third group of vacuum parts 113, and then the leather is blown into the unqualified channel 14 through the exhaust of the third group of vacuum parts 113. The conveying roller 115 conveys the leather away. If it is judged to be qualified, the leather is blown into the output channel 13 through the exhaust of the second group of vacuum parts 113, and the leather is conveyed to the rotating island 114 through the conveying roller 115. Then the rotating island 114 is rotated to align with the corresponding drying conveyor belt 41.

The conveying roller 115 conveys the leather to the drying conveyor belt 41 and collides with the two positioning angle plates 43. The drying conveyor belt 41 is conveyed forward, so that the remaining two positioning angle plates 43 of the same group are conveyed to the same plane position, so that the four positioning angle plates 43 clamp and limit the leather. Then the drying conveyor belt 41 is conveyed according to the length distance of each group of positioning angle plates 43 as a work station distance, and the humidity is detected by the remote humidity detection submodule 33. If the humidity is not enough, oil is added through the injector 44. Finally, after drying, the color fixing agent is wiped on the color fixing part 45 to complete the dyeing.

[0050] The present application embodiment discloses a leather dyeing method. Figure 6 , the leather dyeing method comprises the following steps: S1. Acquire a detection signal and timing data, where the detection signal includes image recognition data; S11, determining the rubbing trajectory data through the image recognition data and the timing data; S12, determining trajectory correction data by comparing the scratch trajectory data with a preset scratch trajectory threshold; S13, determining and outputting the scratch driving data through the trajectory correction data and the preset conversion threshold; S14, determining the rubbing adjustment data through the image recognition data, the rubbing trajectory threshold and the preset color continuity threshold; S15, determining and outputting the rubbing dyeing feeding speed data through the rubbing dyeing adjustment data, the rubbing dyeing driving data and the preset dye consumption threshold.

[0051] In detail: during the circle dyeing process, the trajectory of the rubbing cloth layer 233 rubbed over time can be obtained through image recognition data and timing data, which is the rubbing trajectory data. The rubbing trajectory threshold is the specified circle dyeing trajectory. If there is a difference between the rubbing trajectory data and the rubbing trajectory threshold, it means that there is a problem with the rubbing trajectory at this time. This difference is the trajectory correction data, that is, it is necessary to correct this difference data, such as dye interruption or motor movement speed mismatch. When the rubbing trajectory is continuous but deviated, it means that the motor movement speed of the rubbing drive 23 and the rubbing drive component 235 does not match. The conversion threshold is the conversion relationship between the difference obtained by image recognition and the voltage and current that controls the motor movement rate, so that the difference is converted into voltage and current data for correction. This is rubbing. Driving data; the color continuity threshold is the color difference allowed during the circle dyeing movement. If the color continuity threshold is set to a, and the difference between the colors of the continuous image recognition data corresponding to the continuous time shown by the timing data is greater than a, it means that the color is discontinuous, that is, the circle dyeing is interrupted. According to the frequency and length of the interruption, the corresponding rubbing adjustment data is output, and then combined with the rubbing drive data for adjusting the motor rotation speed before, for example, in order to adjust the trajectory, the motor rotation speed is increased, which will cause the dye consumption speed to further increase. The dye consumption threshold is the relationship between the motor rotation speed and the dye consumption speed. The rubbing feeding speed data is comprehensively obtained and output to increase the speed at which the liquid absorption drive 234 sprays the dye on the liquid absorption sponge 232, so that the wiping cloth layer 233 can wipe out more dye.

[0052] Reference Figure 7 , further comprising the following steps: S2. The detection signal also includes pressure detection data; S21, determining elastic force abnormality data through pressure detection data, rubbing drive data and a preset elastic force threshold; S22, determining abnormal type data through elastic abnormality data, timing data and elastic threshold; S23, determining and outputting the erasure area map data through the timing data, the abnormal type data and the erasure drive data; S24, determining qualified area data by using the rubbing area map data, a preset qualified circular area threshold and a preset qualified square area threshold; S25. Determine and output an unqualified signal based on the qualified area data and a preset qualified area threshold.

[0053] In detail: the elastic threshold is the pressure range of normal leather, and the rubbing drive data includes the moving position and time of the motor. Therefore, when the pressure detection data exceeds the range of the elastic threshold, the position at this time can be determined according to the rubbing drive data, indicating that the leather here has hidden damage, and the corresponding elastic abnormality data is output, and then the elastic abnormality data is compared with the elastic threshold again. For example, hidden damage caused by damaged fibers inside the leather will cause this place to be easily dented and too soft when subjected to force. At this time, the pressure detection data is less than the range of the elastic threshold, while hidden damage caused by entanglement of fibers inside the leather will cause this place to be too hard and difficult to deform. At this time, the pressure detection data is greater than the range of the elastic threshold, thereby obtaining the specific cause of the hidden damage, which is the abnormal type data; and according to the abnormal type data, the rubbing drive data and the corresponding timing data, the position of the leather with hidden damage can be obtained, and According to the graphic data of the entire leather, an image of the area with hidden damage is drawn in the graphic data, which is the rubbing area data, and is output for user viewing; the qualified circular area threshold is to find the circle with the largest area that can be adapted in the rubbing area data according to the circle, and all the leathers in this circle are qualified and do not have hidden damages; the qualified square area threshold is to find the square with the largest area that can be adapted in the rubbing area data according to the square or rectangle, and all the leathers in this square are qualified and do not have hidden damages, and the circle and the square can overlap, which is the qualified area data. This data excludes low-value fragmented areas, and compares the qualified area data with the qualified area threshold to calculate whether the value of the leather is qualified. If it is unqualified, the leather is judged to be unqualified, and does not enter the subsequent drying process, and is directly output from the unqualified channel 14.

[0054] Reference Figure 8 , further comprising the following steps: S3, obtaining drying data, the detection signal also includes humidity detection data; S31, determining an oil replenishment signal based on humidity detection data and a preset edge warping humidity threshold and outputting the signal; S32, determining the drying coefficient through the rubbing area map data, the qualified area data and the abnormal type data; S33, determining abnormal humidity data through the drying coefficient, drying data, humidity detection data and oil replenishment signal; S34, determining an oil replenishment signal based on the abnormal humidity data and the edge warping humidity threshold and outputting the signal.

[0055] In detail: remote humidity sensors at different positions correspond to humidity detection data for different purposes. For example, the humidity detection data installed on the positioning angle plate 43 is used to compare and judge with the humidity threshold for warping. When the humidity detection data is lower than the humidity threshold for warping, the leather will warp, so it is necessary to output an oil replenishment signal for oil replenishment. According to the rubbing area map data and the qualified area data, the location of the hidden damage can be determined, and then combined with the abnormal type data, it can be determined whether the location of the hidden damage is prone to drying and causing the leather to bulge or dent. The coefficient of easy drying is the drying coefficient, and the humidity detection data installed on the drying conveyor belt 41 is usually combined with the drying coefficient to determine whether the hidden damage is too dry. This also needs to be combined with the drying data, which is the temperature and airflow velocity in the oven 42, and combined with the oil replenishment signal for oil replenishment before, the humidity of the hidden damage is calculated, and then whether oil replenishment is needed.
