[0002] In modern times, as people's lives become more and more affluent, they like to express themselves more and more, and the fashion of clothing has naturally seen a variety of styles and colors.

[0003] Leather of different colors needs to be dyed after tanning to dye the leather into the required color, but the dyeing of leather needs to pay attention to the dyeing time. Different dyeing times will be required according to the different types of leather, the different colors of dye, and the depth of color. Even the different degrees of tanning of the leather in the tanning process will lead to different dye penetration efficiency, resulting in different dyeing times. The dye will gradually fade with use and need to be blended again. The operation is cumbersome and requires the master to have sufficient experience. Summary of the invention

[0004] In order to improve the problem that leather dyeing and immersion dyeing operations are cumbersome and require high craftsmanship, the present application provides a leather dyeing device, a dyeing method and a storage medium thereof.

[0005] The present application provides a leather dyeing device, which adopts the following technical solution: A leather dyeing device comprises a dyeing seat, on which a dyeing pool for dyeing leather is formed, a plurality of partition plates for carrying leather are arranged on the inner wall of the dyeing pool, and the plurality of partition plates are distributed along the depth direction of the dyeing pool, a guide plate is rotatably arranged on the dyeing seat, a transmission member for transmitting leather into the dyeing pool is arranged on the dyeing seat, the guide plate rotates to connect the leather transmitted on the transmission member with different partition plates, and a transmission component for transmitting leather out is arranged on the partition plate.

[0006] By adopting the above technical solution, the guide plate is rotated to different partition plates, so that the leather is transferred from the dyeing seat to the designated partition plates in an orderly manner, so that the leather is distributed up and down in an orderly manner, reducing the probability of the leather sticking together, making it difficult for the dye to penetrate, resulting in poor dyeing effect, and improving the dyeing effect.

[0007] Optionally, the guide plate is provided with a plurality of first give way slots, and first give way strips are formed between adjacent first give way slots; the partition plate is provided with a plurality of second give way slots for the first give way strips to enter, and second give way strips are formed between adjacent second give way slots; the first give way slots are used for the second give way strips to enter.

[0008] By adopting the above technical solution, the ends of the guide plate and the partition plate are staggered, and the first and second clearance grooves provide clearance space for the rotation of the guide plate. At the same time, the first and second clearance strips also support the leather.

[0009] Optionally, a buffer column shaft is rotatably provided on the dyeing seat, and the guide plate is fixed on the buffer column shaft. The leather slides onto the guide plate after passing through the outer wall of the buffer column shaft. A hook plate and a guide arc plate are provided on the guide plate. A limiting groove for clamping the leather to limit the sliding direction of the leather is formed between the hook plate and the guide plate. The opening of the limiting groove is adapted to the distance between the adjacent partition plates, and the guide arc plate is used to guide the leather transmitted on the transmission member into the limiting groove.

[0010] By adopting the above technical scheme, the rotation radius of the guide plate is expanded by the buffer column shaft, and the buffer column shaft also supports the leather, so that when the angle of the leather changes when it is transferred from the upper end surface of the dyeing seat to the guide plate, the buffer column shaft provides support, which reduces the probability of the leather being damaged by bending at too large an angle when the guide plate rotates to a larger angle, thereby playing a protective role. At the same time, the leather is clamped by the limit groove, which reduces the probability that the leather will be unable to continue to reach the designated partition plate due to the buoyancy of the liquid when entering the dyeing pool, thereby making the process of the leather entering the partition plate smoother.

[0011] Optionally, a plurality of water pumps are provided on the bottom wall of the immersion pool, a plurality of circulation channels are opened in the immersion seat, the circulation channels are connected with the immersion pool near the bottom wall of the immersion pool to form a water inlet, the water pump is arranged in the water inlet and pumps liquid into the water inlet, the circulation channels are connected with the immersion pool near the opening of the immersion pool to form a water outlet, the water outlet extends along the length direction of the immersion pool, the water outlet is narrowly opened along the depth direction of the immersion pool, and the water outlet opening is covered with a heating net.

At the same time, through the opening setting of the water outlet, the water outlet can be more uniform in the horizontal direction, reducing the probability that the water outlet at one point will affect the entire heat dissipation liquid surface too little, so that the temperature is more uniform.

[0013] Optionally, the transmission component includes a plurality of trigger blocks telescopically arranged on the inner wall of the immersion pool, the trigger blocks corresponding to the partition plate, a transmission roller is rotatably arranged on the partition plate, a first reversing tooth is slidably arranged on the end of the transmission roller, a round table is arranged on the first reversing tooth, a trigger rod is slidably arranged in the immersion seat, a guiding inclined surface is formed on the trigger rod for the trigger block to contact and push the trigger rod to slide, a transmission driving member is arranged in the immersion seat, a second reversing tooth is arranged on the rotating shaft of the transmission driving member, the trigger rod slidably contacts the round table to push the first reversing tooth to slide and engage with the second reversing tooth.

[0014] By adopting the above technical solution, when the guide plate rotates to be connected with the corresponding partition plate, the transmission roller on this partition plate is engaged and rotated with the transmission drive member by pressing the trigger block, while the transmission rollers on other partition plates remain disconnected from the transmission drive member, thereby reducing the probability that the leather on other partition plates is mistakenly transmitted and falls to the bottom of the dyeing tank, improving stability, and at the same time achieving one transmission drive member to control the rotation and stop of the transmission tubes on all partition plates, thereby reducing the number of drive sources and reducing costs.

[0015] Optional, including: A color detection module, embedded in the partition plate, used to detect the color of the leather, obtain color detection data and output it; A temperature detection module, arranged on the bottom wall of the immersion tank, is used to detect the temperature of the liquid at the bottom of the immersion tank, obtain temperature detection data and output it; A liquid storage tank, arranged on the dyeing seat, for storing dye, with a discharge port for discharging the dye facing the dyeing pool; A data processing module receives the color detection data and the temperature detection data, performs data processing and calculation, obtains a processing signal and outputs it; The control mechanism is arranged on the liquid storage tank and is used for receiving the processing signal to control the opening and closing of the discharge port of the liquid storage tank.

[0016] By adopting the above technical solution, the color and temperature are monitored and automatically adjusted, so that the dye color and liquid temperature in the dyeing pool can be maintained in the optimal range, which greatly improves the dyeing efficiency and is more convenient and quick.

[0017] The present application provides a leather dyeing method, which adopts the following technical solution: A leather dyeing method comprising: Acquiring the color detection data and timing data, the processing signal including dye blending data and leather color data; Determine whether the leather is impregnated with a signal by using the color detection data and a preset regional color difference threshold; Determine the color difference of the detection point by using the leather dyeing signal and the color detection data; Determine the dye tank color data by the color difference of the detection point, the preset partition plate spacing threshold and the preset color threshold; Determine the dye blending data based on the dye pool color data and a preset dyeing threshold value and output it; Determine color fluctuation data through the leather dyeing signal, the color detection data and the timing data; Determine the lightest color data according to the color fluctuation data; The leather color data is determined and outputted through the lightest color data, the dye pool color data and a preset proximity distance threshold.

[0020] By adopting the above technical scheme, the influence of heat dissipation is reduced, the stability of heating is improved, the calculation accuracy is improved, and at the same time, the flow rate is increased to harmonize the added dye. It can also be ensured that the temperature will not be reduced while the flow rate is increased, the dyeing conditions are more stable, and the dyeing effect is improved.

[0055] The implementation principle of a leather dyeing device in an embodiment of the present application is as follows: when the leather needs to be put into the dyeing pool 11, the buffer column shaft 135 is first rotated to rotate the guide plate 13 to the end of the second give way strip 134 of the uppermost partition plate 12, so that the first give way strip 132 on the guide plate 13 presses the trigger block 211, and the trigger block 211 pushes the first reversing tooth 22 to slide through the trigger rod 24 and engages with the second reversing tooth 261. At this time, the rotation of the transmission drive member 26 only drives the transmission roller 21 on the uppermost partition plate 12 to rotate. At this time, the transmission member 14 transmits the leather on the upper end surface of the dyeing seat 1 to the guide plate 13 and enters the partition plate 12. When the leather leaves the transmission member 14, one end of the leather has entered the transmission roller 21. At this time, it continues to be transmitted through the transmission roller 21. The operation of other lower partition plates 12 is the same, and the same is true when the leather needs to be taken out from the partition plate 12.

[0056] The present application embodiment discloses a leather dyeing method. Fig.10 , leather dyeing method steps: S1, obtaining color detection data and timing data, and processing signals including dye blending data and leather color data; S11, determining whether the leather is impregnated with a signal by using color detection data and a preset regional color difference threshold; S12, determining the color difference of the detection point according to the leather dyeing signal and the color detection data; S13, determining the dye tank color data by detecting the color difference of the points, the preset partition plate spacing threshold and the preset color threshold; S14, determining dye blending data based on dye pool color data and a preset dyeing threshold value and outputting the data; S15, determining color fluctuation data according to the leather dyeing signal, color detection data and timing data; S16, determining the lightest color data through the color fluctuation data; S17, determining leather color data through the lightest color data, dye pool color data and a preset proximity distance threshold and outputting the data.

[0057] In detail: the color detection data is the data of all colors in an area detected. If there is leather, there will be obvious color difference between the color of the leather and the color of the liquid other than the leather. The regional color difference threshold is used to determine whether there is leather. If the color difference in the color detection data in the same area is greater than the regional color difference threshold, it means that leather exists. At this time, the signal of whether the leather is dyed is yes. If there is no color difference or the color difference is less than the regional color difference threshold, it means that the detection range is all liquid and there is no leather. At this time, the signal of whether the leather is dyed is no; if the signal of whether the leather is dyed is no, then the color detection data will have different colors. For example, the color detected between the color detection sensor and the lower end face of the previous partition plate 12 is different from the color directly facing the dyeing pool. 11. The color of the liquid surface detected is different. At this time, the lightest color is taken as the color difference of the detection point. The partition plate spacing threshold is the distance between adjacent partition plates. The color threshold is the relationship between the distance and the color depth. The distance between the partition plates can be obtained according to the partition plate spacing threshold and the color threshold, which leads to the influence on the lightest color, so as to calculate the true color of the liquid in the immersion and dyeing pool 11, which can be regarded as the color of a thin layer brushed on the leather, which is the dyeing pool color data; the dyeing threshold is the data of the dyeing pool color required to dye the leather into the corresponding color. The dyeing pool color data is compared with the dyeing threshold to obtain the color difference, which is the dye blending data, and output to the control mechanism 44. The control mechanism 44 is operated to open and release a certain amount of dye for color blending; When the signal indicating whether the leather is being dyed is yes, it indicates that there is leather being dyed. At this time, the leather will float up and down, resulting in a change in the distance between the leather and the color sensor, which increases the thickness of the liquid that needs to be penetrated. At this time, the detected color depth will change, so as to obtain a color fluctuation curve in combination with the timing data. The x-coordinate is the color detection data, and the y-coordinate is the timing data, which is the color fluctuation data. Then the lightest color data is taken, which is the lightest color data. When the leather is placed on the color sensor, due to the certain hardness and toughness of the leather, the leather cannot be completely attached to the color sensor, and the proximity distance threshold is the interval of the shortest distance when the leather is naturally placed on the color sensor, so as to obtain the true color of the leather surface after eliminating the interference of the liquid color, which is the leather color data, and output it to the user so that the user can take it out after the leather color reaches a sufficient depth.

[0058] Reference Fig.11 , further comprising the following steps: S2, obtaining temperature detection data, and the processed signal also includes flow data and heating data; S21, determining heat dissipation rate data through temperature detection data, timing data, flow data and heating data; S22, determining a flow influence coefficient through a plurality of heat dissipation rate data and flow data; S23, determining new heating data through temperature detection data, a preset temperature threshold and heat dissipation rate data, and replacing the original heating data; S24, determining new flow data by using the dye blending data and a preset blending threshold, and replacing the original flow data; S25. Determine new heating data through the new flow data, flow influence coefficient, heat dissipation rate data and original heating data, and replace the original heating data.

[0059] In detail: the temperature detection data is to detect the temperature of the liquid at the bottom of the immersion pool 11, the heating data is the power signal output by the processor to the heating wire, that is, the heat generated by the heating wire, the flow data is the power signal output by the processor to the water pump 3, that is, the efficiency of the water pump 3 pumping water, when the flow data is 0, the heat emitted by the heating wire minus the heat represented by the temperature detection data, combined with the timing data, the heat dissipation speed of the liquid surface in a static state can be obtained, which is the heat dissipation rate data, and then when the flow data is not 0, the difference between the heat dissipation rate data obtained and the heat dissipation rate data in a static state is the additional heat dissipation caused by the flow of the liquid surface, and the relationship between this and the flow data is the flow influence coefficient, the temperature threshold is the temperature required for the leather in the immersion to achieve the best immersion efficiency, the difference between the temperature threshold and the temperature detection data is the temperature that needs to be increased, at this time, the new heating data can be obtained in combination with the heat dissipation rate data and output to the heating wire; After outputting the dye blending data and adding the dye, it is necessary to speed up the liquid flow to blend the newly added dye, but a fast flow rate will lead to faster heat dissipation, so first determine the flow rate required to blend the dye based on the blending threshold, output this flow output to the water pump 3 for control, and then combine the flow data with the flow influence coefficient to obtain how much additional heat dissipation the flow rate corresponding to the flow data will increase, and then add the additional heat dissipation to the original heat dissipation rate data to obtain new heat dissipation rate data, and combine the new heat dissipation rate data to obtain new heating data, which can be output to the heating wire.
