Description

Technical Field

[0001] This invention relates to the field of leather dyeing technology, specifically a method for dyeing high-performance green leather based on intelligent equipment. Background Technology

[0002] Leather is animal hide that has undergone physical and chemical processing such as hair removal and tanning, resulting in a modified appearance that is less prone to decay. Leather is composed of natural protein fibers tightly woven in three-dimensional space, and its surface has a special grain layer with natural grain and luster, and a comfortable feel. In the process of human evolution, people discovered that the juices of some plants or mineral oils have a certain tanning effect on leather. When raw hides are soaked in these juices, they become more breathable and rot-resistant, thus giving the hides physical and chemical properties such as softness, tear resistance, and flexural strength.

[0003] In the production process of leather, in order to improve the grain and luster of the surface, the surface is usually dyed. Some leathers need to be directly immersed in dye for dyeing. Some leathers are not easy to soak. If the soaking time is too long, the leather is prone to peeling. In this case, workers need to use sponges to repeatedly wipe the leather. This method can not only improve the dyeing effect, but also make it easier to control the dyeing depth. However, manual dyeing is labor-intensive and inefficient, and cannot be mass-produced. Summary of the Invention

[0004] The purpose of this invention is to provide a method for dyeing high-performance green leather based on intelligent equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a method for dyeing high-performance green leather based on intelligent equipment, comprising the following steps:

[0006] S1. Prepare the leather to be dyed and wipe it clean to keep the surface of the leather clean;

[0007] S2. Lay the cleaned leather flat on the worktable of the dyeing device, and then start the dyeing device to dye the leather.

[0008] The dyeing device in S2 includes a base, a support frame, a limiting mechanism, a dyeing mechanism, and a feeding mechanism. The support frame is fixed above the base, and a worktable is provided on the inner side of the support frame above the base. The limiting mechanism is located above the support frame, and the feeding mechanism is located on the side of the support frame. A first transverse slide rail is provided on the back of the support frame, and a second slide rail is symmetrically arranged on the inner side wall of the support frame. A transverse screw is provided in the first slide rail, and the end of the screw is rotatably connected to the first slide rail. A fixed frame, a processor, a controller, and a drive motor corresponding to the screw are provided on the side of the support frame away from the feeding mechanism. The drive shaft of the drive motor is connected to the screw. The fixed frame is located above the support frame, and a threaded slider is threadedly connected to the screw. A support plate is provided on the threaded slider, and the dyeing mechanism is provided on the support plate. By laying the leather flat on the dyeing device, then limiting the leather by the limiting mechanism, and then feeding dye into the dyeing mechanism using the feeding mechanism (using alcohol dye), the leather can be dyed using the dyeing mechanism.

[0009] Preferably, the limiting mechanism includes a rotating plate, a rotating rod, a connecting rod, a rotating seat, a first electric telescopic rod, a hanging rod, and a pressure rod. A through slot is provided above the support frame. The rotating plate is rotatably connected to the through slot via a rotating shaft. Two rotating rods are symmetrically rotatably connected to both ends of the rotating plate. A connecting rod is provided at the middle position above the rotating plate. The end of the connecting rod is rotatably connected to the rotating seat. The rotating seat is provided with a first electric telescopic rod. The end of the first electric telescopic rod is fixed to the fixed frame. Each rotating rod is provided with a hanging rod. The end of the hanging rod is fixed with a pressure rod. By pushing the connecting rod to the side with the first electric telescopic rod, one end of the rotating plate is raised, and the corresponding other end moves downward and presses against the leather, thereby limiting the leather. Conversely, when the first electric telescopic rod pulls the rotating plate backward, the previously raised end can be pressed down onto the leather.

[0010] Preferably, the dyeing mechanism includes a second electric telescopic rod, a middle plate, a fabric tube, and side plates. The second electric telescopic rod is fixed to a support plate, and the middle plate is fixed to the end of the second electric telescopic rod. Two side plates are symmetrically arranged on both sides of the middle plate, and a sponge is provided below each side plate. A fabric tube is arranged below the middle plate, and multiple nozzles are evenly arranged on the fabric tube. The middle plate is pushed down by the second electric telescopic rod, and the dye is fed into the fabric tube by the feeding mechanism and sprayed out through the fabric tube to dye the leather. The screw is rotated by the drive motor, which moves the dyeing mechanism. The sponge is used to spread the dye evenly, improving the dyeing effect.

[0011] Preferably, the material conveying mechanism includes a storage tank and a material conveying pump. The suction port and the delivery port of the material conveying pump are respectively connected to a first pipe and a second pipe. The first pipe is connected to the discharge port of the storage tank, and the second pipe is connected to the inlet of the fabric pipe. The material conveying pump draws the dye in the storage tank into the fabric pipe.

[0012] Preferably, each side plate is equipped with a spacing sensor. The spacing sensor is electrically connected to the processor, and the processor is electrically connected to the controller. The controller is electrically connected to the first electric telescopic rod, the second electric telescopic rod, the drive motor, and the feed pump. During operation, the first electric telescopic rod pushes the rotating plate, and then the second electric telescopic rod pushes the dyeing mechanism downward, causing the sponge to contact the leather. The feed mechanism injects dye into the fabric tube and sprays it out. Then, the drive motor drives the screw to rotate clockwise, moving the dyeing mechanism. The sponge spreads the dye evenly. During the movement, when the spacing sensor on the side plate approaches the raised hanging rod, the spacing sensor detects an over-distance. Once the preset value is exceeded, the spacing sensor transmits the information to the processor, which processes the information and feeds it back to the controller. At this point, the controller activates the first electric telescopic rod to reverse its output, lifting the other end of the rotating plate. Simultaneously, the controller activates the drive motor to reverse its output, causing the screw to rotate counterclockwise and moving the dyeing mechanism toward the lifted rotating plate. Meanwhile, the spacing sensor on the other side plate detects that the spacing exceeds the preset value, and then transmits the information to the processor again. The controller then activates the first electric telescopic rod to push the rotating plate back, while simultaneously activating the drive motor to rotate clockwise. This process is repeated to achieve repeated dyeing of the leather.

[0013] Preferably, a limiting slider is fixed to the side of the boom, and the end of the limiting slider is inserted into the second slide rail and slidably connected. By setting the limiting slider on the side of the boom, it is ensured that the boom maintains vertical movement when moving.

[0014] Preferably, the storage box is provided with a feeding port at the top, and an end cap is provided on the feeding port. The end cap is threadedly connected to the feeding port. The storage box is provided with a venting port at the lower side, and a venting valve is provided on the venting port. The venting port is mainly used to vent the dye in the storage box. The end cap can be opened and then dye can be added to the storage box. The end cap can also prevent the dye in the storage box from evaporating too quickly.

[0015] Preferably, a pipe rack is provided above the support frame near the side, and the second pipe rests on the pipe rack. The pipe rack is mainly used to support the second pipe.

[0016] Preferably, the second conduit is a flexible hose, which is used to facilitate the movement of the dyeing mechanism.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention lays the leather flat on the workbench, then uses a restricting mechanism to restrict the leather, then uses a feeding mechanism to input dye into the cloth tube of the dyeing mechanism and spray it out, the dye is spread on the leather by the sponge of the dyeing mechanism, and the dyeing mechanism repeatedly dyes the leather until the required dyeing depth is reached, then the dyeing device can be turned off. Moreover, the dyeing process of the present invention does not require manual dyeing by workers, thus realizing automated processing, improving the practicality of the present invention and reducing the workload of workers.

[0028] Please see Figure 1-6 This invention provides a technical solution: a method for dyeing high-performance green leather based on intelligent equipment, comprising the following steps:

[0029] S1. Prepare the leather to be dyed and wipe it clean to keep the surface of the leather clean;

[0030] S2. Lay the cleaned leather flat on the workbench 5 of the dyeing device, and then start the dyeing device to dye the leather.

[0031] The dyeing apparatus in S2 includes a base 1, a support frame 3, a limiting mechanism 2, a dyeing mechanism 4, and a conveying mechanism 6. The support frame 3 is fixed above the base 1, and a workbench 5 is provided on the inner side of the support frame 3 above the base 1. The limiting mechanism 2 is located above the support frame 3, and the conveying mechanism 6 is located on the side of the support frame 3. A first transverse slide rail 32 is provided on the back of the support frame 3, and second slide rails 37 are symmetrically arranged on the inner sidewall of the support frame 3. A transverse screw 33 is provided in the first slide rail 32, and the end of the screw 33 is rotatably connected to the first slide rail 32. The support frame 3 is located away from the conveying mechanism 6. One side is equipped with a fixed frame 31, a processor 8, a controller 9, and a drive motor 36 corresponding to the screw 33. The drive shaft of the drive motor 36 is connected to the screw 33. The fixed frame 31 is located above the support frame 3. A threaded slider 34 is threadedly connected to the screw 33. A support plate 35 is provided on the threaded slider 34. A dyeing mechanism 4 is provided on the support plate 35. By laying the leather flat on the dyeing device, then restricting the leather by the limiting mechanism 2, and then feeding the dye to the dyeing mechanism 4 by the feeding mechanism 6, the dyeing mechanism 4 can be used to dye the leather. The dye is an alcohol dye.

[0032] Furthermore, the limiting mechanism 2 includes a rotating plate 21, a rotating rod 22, a connecting rod 23, a rotating seat 24, a first electric telescopic rod 25, a hanging rod 26, and a pressure rod 27. A through slot is provided above the support frame 3. The rotating plate 21 is rotatably connected to the through slot via a rotating shaft. Two rotating rods 22 are symmetrically rotatably connected to both ends of the rotating plate 21. A connecting rod 23 is provided at the middle position above the rotating plate 21. The end of the connecting rod 23 is rotatably connected to the rotating seat 24. The first electric telescopic rod 25 is provided on the rotating seat 24. The end of the first electric telescopic rod 25 is fixed to the fixed frame 31. A hanging rod 26 is provided on each rotating rod 22. The end of the hanging rod 26 is fixed to the pressure rod 27. The connecting rod 23 is pushed to the side by the first electric telescopic rod 25, thereby raising one end of the rotating plate 21 and moving the corresponding other end downward and pressing it onto the leather, thus limiting the leather. Conversely, when the first electric telescopic rod 25 pulls the rotating plate 21 backward, the previously raised end can be pressed down onto the leather.

[0033] Furthermore, the dyeing mechanism 4 includes a second electric telescopic rod 41, a middle plate 42, a fabric tube 43, and side plates 44. The second electric telescopic rod 41 is fixed on the support plate 35, and the middle plate 42 is fixed to the end of the second electric telescopic rod 41. Two side plates 44 are symmetrically arranged on both sides of the middle plate 42. A sponge 441 is provided below each side plate 44. A fabric tube 43 is provided below the middle plate 42, and multiple nozzles 431 are evenly arranged on the fabric tube 43. The middle plate 42 is pushed down by the second electric telescopic rod 41, and the dye is input into the fabric tube 43 by the feeding mechanism 6 and sprayed out through the fabric tube 43 to dye the leather. The screw 33 is rotated by the drive motor 36, which drives the dyeing mechanism 4 to move. The dye is evenly spread by the sponge 441 to improve the dyeing effect.

[0034] Furthermore, the material conveying mechanism 6 includes a storage tank 61 and a material pump 62. The suction port and the delivery port of the material pump 62 are respectively connected to a first pipe 63 and a second pipe 64. The first pipe 63 is connected to the discharge port of the storage tank 61, and the second pipe 64 is connected to the inlet of the fabric pipe 43. The material pump 62 draws the dye in the storage tank 61 into the fabric pipe 43.

[0035] Furthermore, each of the side plates 44 is equipped with a spacing sensor 442. The spacing sensor 442 is electrically connected to the processor 8, and the processor 8 is electrically connected to the controller 9. The controller 9 is electrically connected to the first electric telescopic rod 25, the second electric telescopic rod 41, the drive motor 36, and the feed pump 62. During operation, the first electric telescopic rod 25 pushes the rotating plate 21, and then the second electric telescopic rod 41 pushes the dyeing mechanism 4 downward, so that the sponge 441 comes into contact with the leather. The feed mechanism 6 injects dye into the fabric tube 43 and sprays it out. Then, the drive motor 36 drives the screw 33 to rotate clockwise, driving the dyeing mechanism 4 to move. The sponge 441 spreads the dye evenly. During the movement, when the spacing sensor 442 on the side plate 44 approaches the raised hanging rod 26, If the spacing sensor 442 exceeds the preset value, it will transmit the information to the processor 8. The processor 8 will process the information and feed it back to the controller 9. At this time, the controller 9 will activate the first electric telescopic rod 25 to output in the reverse direction, lifting the other end of the rotating plate 21. Simultaneously, the controller 9 will activate the drive motor 36 to output in the reverse direction, driving the screw 33 to rotate counterclockwise, moving the dyeing mechanism 4 toward the lifted rotating plate 21. At the same time, the spacing sensor 442 on the other side plate 44 will detect the distance. When the spacing detected by the spacing sensor 442 on the other side plate 44 exceeds the preset value, it will transmit the information to the processor 8 again. Then, the controller 9 will activate the first electric telescopic rod 25 to push the rotating plate 21 back, and simultaneously activate the drive motor 36 to rotate clockwise. This process will be repeated to achieve repeated dyeing of the leather.

[0036] Furthermore, a limiting slider 261 is fixed to the side of the boom 26. The end of the limiting slider 261 is inserted into the second slide rail 37 and is slidably connected. By setting the limiting slider 261 on the side of the boom 26, it is ensured that the boom 26 maintains vertical movement when moving.

[0037] Furthermore, a feeding port 612 is provided on the top of the storage tank 61, and an end cap is provided on the feeding port 612. The end cap is threadedly connected to the feeding port 612. A vent 611 is provided on the lower side of the storage tank 61, and a vent valve is provided on the vent 611. The vent 611 is mainly used to vent the dye in the storage tank 61. The end cap can be opened, and then dye can be added to the storage tank 61. The end cap can also prevent the dye in the storage tank 61 from evaporating too quickly.

[0038] Furthermore, a pipe rack 7 is provided above the support frame 3 near the side, and the second pipe 64 rests on the pipe rack 7. The pipe rack 7 is mainly used to support the second pipe 64.

[0039] Furthermore, the second conduit 64 is a flexible hose, which is used to facilitate the movement of the dyeing mechanism 4.

[0040] Working principle: When in use, the staff first cleans the surface of the leather, then lays the cleaned leather flat on the workbench 5, and then connects the power supply to the first electric telescopic rod 25, the second electric telescopic rod 41, the drive motor 36 and the water pump.

[0041] During the dyeing process, simply activate the first electric telescopic rod 25 to push the connecting rod 23 forward. This causes the connecting rod 23 to rotate the rotating plate 21 on the support frame 3. The rotating plate 21 then lifts one pressure plate through the hanging rod 26 while pressing down the other pressure plate, causing the pressure plate to press onto the leather and thus hold the leather in place.

[0042] Then, the second electric telescopic rod 41 is activated, pushing the middle plate 42 downwards. This causes the middle plate 42 to move the side plates 44 and the fabric tube 43 downwards. The feed pump 62 is then activated, drawing fuel from the storage tank 61 through the first pipe 63 and injecting it into the fabric tube 43 through the second pipe 64. The fuel is then sprayed out through the nozzle 431 on the fabric tube 43. Simultaneously, the drive motor 36 is activated, causing the screw 33 to rotate clockwise. This causes the screw 33 to move the threaded slider 34, which in turn moves the dyeing mechanism 4 towards the raised side of the hanging rod 26. During this movement, the sponge 441 spreads the fuel. When the spacing sensor 442 on one side plate 44 approaches the raised hanging rod 26, if the spacing sensor 442 exceeds a preset value, it will transmit information to... The processor 8 processes the information and feeds it back to the controller 9. At this time, the controller 9 will automatically activate the first electric telescopic rod 25 to output in reverse, pulling the connecting rod 23 back. The previously raised pressure plate will then move downward and press down on the leather, while the pressure plate that was originally pressing on the leather will be raised. Simultaneously, the controller 9 will start the drive motor 36 to output in reverse, driving the screw 33 to rotate counterclockwise, causing the screw 33 to drive the threaded slider 34 to move in the opposite direction. At the same time, the spacing sensor 442 on the other side plate 44 will detect the raised pressure plate. This process is repeated to achieve repeated dyeing of the leather. The worker can observe the dyeing depth of the leather from the side. If the desired color is achieved, the first electric telescopic rod 25 can be used to push the rotating plate 21 to raise both pressure plates at the same time, and the second electric telescopic rod 41 can be used to pull the dyeing mechanism 4 back. Then the dyed leather can be taken out, completing the leather dyeing operation.

[0043] 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.
