The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] The following describes an embodiment of the present invention based on its overall structure.

[0030] A water-saving tanning equipment for cowhide processing, such as Figure 1-8 As shown, it comprises a U-shaped frame 100, the inner wall of the U-shaped frame 100 is rotatably connected with round shafts 110 on both sides, a tanning cylinder 120 is fixed between two sets of round shafts 110, a circulation cleaning assembly 200 is provided at the top of the inner wall of the U-shaped frame 100, and a sealing assembly 300 is provided at the front end of the tanning cylinder 120;

[0031] The circulation cleaning assembly 200 includes a servo motor 210 installed on one side of the U-shaped frame 100, a first pulley 220 is fixed to the output end of the servo motor 210, a connecting shaft 230 is fixed to the end of the first pulley 220 away from the servo motor 210, a pinion 240 is fixed to the end of the connecting shaft 230 away from the first pulley 220, a large gear 250 meshing with each other is provided on one side of the small gear 240, a first reciprocating screw rod 260 is rotatably connected to the center of the large gear 250, a push plate 270 is fixed to one side of the first reciprocating screw rod 260, a first piston rod 280 is provided on the end of the push plate 270 away from the first reciprocating screw rod 260, a first piston cylinder 290 is slidably connected to the surface of the first piston rod 280, a nozzle 2910 is connected to one side of the first piston cylinder 290, and a connecting pipe 2920 is provided on the other side of the first piston cylinder 290, and a storage box 2930 is provided on the end of the connecting pipe 2920 away from the first piston cylinder 290, The end of the box 2930 away from the connecting pipe 2920 is provided with a straw 2940, a gear 2950 is fixed to the middle of the surface of the connecting shaft 230, a ratchet gear 2960 meshing with the gear 2950 is provided on one side, a first base rod 2961 is fixed to the center of the ratchet gear 2960, a second belt 2970 is provided on the surface of the first base rod 2961, and a second base rod 2971 is provided on the inner wall of the second belt 2970 away from the first base rod 2961. A first bevel gear 2980 is fixed at one end, and a second bevel gear 2990 meshing with the first bevel gear 2980 is provided on one side. The second bevel gear 2990 is rotatably connected to the center of the second reciprocating screw rod 2991. The bottom end of the second reciprocating screw rod 2991 penetrates to the top of the storage box 2930 and is fixed with a scraper 2992. A filter screen 2993 fixed to the inner wall of the storage box 2930 is provided on one side of the scraper screen 2992, and a horizontal plate 2994 is fixed on one side of the filter screen 2993.

[0032] The servo motor 210 is started to drive the first pulley 220 to rotate synchronously with the connecting shaft 230, so that the connecting shaft 230 drives the small gear 240 to rotate, and the small gear 240 drives the large gear 250 to rotate synchronously. The large gear 250 drives the first reciprocating screw 260 to move back and forth, and the first reciprocating screw 260 drives the first piston rod 280 to move through the push plate 270, so that the first piston rod 280 slides inside the first piston cylinder 290. When the first piston rod 280 moves back and forth, negative pressure and pressure are generated in the first piston cylinder 290. Under the action of negative pressure, the suction pipe 2940 can extract liquid from the tanning cylinder 120, and the liquid enters the storage box 2930 through the suction pipe 2940. When entering the storage box 2930, it will pass through the filter 2993, so that the filter 2993 can effectively filter the residue in the liquid. Finally, It enters the first piston cylinder 290, and then the liquid enters the nozzle 2910 under the action of pressure, and is finally ejected from the nozzle 2911, re-entering the tanning cylinder 120 to process the cowhide, which can effectively improve the tanning effect of the cowhide. At the same time, by recycling the tanning liquid, the consumption of water and tanning agent can be reduced, thereby reducing production costs. Circulating filtration can also extend the service life of the tanning liquid, thereby improving resource utilization efficiency. When too much residue is adsorbed on the surface of the filter 2993, the servo motor 210 is reversed to make the connecting shaft 230 drive the gear 2950 to rotate, and the gear 2950 drives the ratchet gear 2960 to rotate synchronously. The ratchet gear 2960 drives the second base rod 2971 and the first bevel gear 2980 to rotate through the first base rod 2961 and the second belt 2970. The first bevel gear 2980 drives the second bevel gear 2990 to rotate, so that the second bevel gear 2990 drives the second reciprocating screw rod 2991 to move back and forth up and down, and the second reciprocating screw rod 2991 drives the scraper 2992 to clean the residue adsorbed on the surface of the filter screen 2993, so that the residue falls into the empty groove 2995. By cleaning the filter screen 2993, the processing efficiency of cowhide can be further improved.

[0033] Please refer to Figure 2 A first belt 221 is provided on the surface of the first pulley 220 , and a second pulley 222 is installed on the inner wall of the first belt 221 at one end away from the first pulley 220 , and the inner wall of the second pulley 222 is fixedly connected to the tanning cylinder 120 .

[0034] The servo motor 210 is started to drive the first pulley 220 to rotate, and then the first belt 221 drives the second pulley 222 to rotate synchronously with the tanning cylinder 120, so as to facilitate the tanning of cowhide.

[0035] Please refer to Figures 3 to 5One end of the nozzle 2910 passes through one side of the tanning cylinder 120, and a nozzle 2911 is provided at the end of the nozzle 2910 away from the first piston cylinder 290, and one end of the suction pipe 2940 passes through the other side of the tanning cylinder 120, and a one-way valve is provided at the connecting end of the nozzle 2910, the connecting pipe 2920 and the first piston cylinder 290, and the filter screen 2993 is arranged on the side close to the suction pipe 2940, and the bottom end of the push plate 270 is attached to the bottom end of the inner wall of the U-shaped frame 100, and the side of the horizontal plate 2994 away from the filter screen 2993 is hollow, and an empty groove 2995 is provided between the bottom end of the horizontal plate 2994 and the bottom end of the inner wall of the storage box 2930.

[0036] By providing an empty groove 2995 between the bottom end of the horizontal plate 2994 and the bottom end of the inner wall of the storage box 2930 , the scraped impurities can be effectively flowed into the empty groove 2995 .

[0037] Please refer to Figure 1 , Figure 6 , Figure 7 and Figure 8 The sealing assembly 300 includes a rotating shaft 310 fixedly connected to the tanning cylinder 120, and a cover plate 320 is rotatably connected to the surface of the rotating shaft 310. Second piston cylinders 330 are fixed on both sides of the inside of the tanning cylinder 120, and a second piston rod 340 is slidably connected to the inner wall of the second piston cylinder 330. A first spring 341 is sleeved on the surface of the second piston rod 340, and an extrusion block 350 is fixed at one end of the second piston rod 340. An air pipe 360 ​​is connected to one side of the second piston cylinder 330, and a sealing air bag 370 is provided at the end of the air pipe 360 ​​away from the second piston cylinder 330. Two groups of blocks 380 are slidably connected in the tanning cylinder 120, a second spring 390 is fixed to one side of the block 380, and a pull rod 3910 is fixed to the front end of the block 380. The pull rod 3910 is slidably connected to the tanning cylinder 120, and slots 351 matching the block 380 are provided on both sides of the cover plate 320.

[0038] The staff puts the cowhide into the tanning cylinder 120, and adds a proper amount of water and tanning liquid into the tanning cylinder 120, and then closes the cover plate 320, and the cover plate 320 rotates and closes through the rotating shaft 310. When the cover plate 320 is closed, the squeezing blocks 350 on both sides are squeezed, so that the squeezing blocks 350 drive the second piston rod 340 to move and stretch the first spring 341, and at the same time, the gas inside the second piston cylinder 330 is compressed, so that the gas enters the sealing airbag 370 through the air pipe 360, so that the sealing airbag 370 expands, and then the gap between the cover plate 320 and the tanning cylinder 120 is sealed, which effectively prevents the tanning cylinder 120 from being damaged. When the cowhide is processed during rotation, tanning liquid and water leak out, thereby maintaining a stable environment in the tanning cylinder 120. At the same time, it can effectively prevent external impurities or air from entering the tanning cylinder 120, interfering with the chemical process and affecting the final quality of the leather. When the cover 320 is completely closed, the second spring 390 and the block 380 can be used to insert the block 380 into the slot 351, thereby fixing the cover 320. When the processing is completed, the block 380 is disengaged from the limit of the cover 320 by pulling the pull rods 3910 on both sides, and then the cover 320 is opened to take out the processed leather.

[0039] When in use, the staff puts the cowhide into the tanning cylinder 120 and then closes the cover 320. When the cover 320 is closed, the sealing airbag 370 will expand, thereby sealing the gap between the cover 320 and the tanning cylinder 120, effectively preventing the leakage of tanning liquid and water when the tanning cylinder 120 is rotating and processing the cowhide, thereby maintaining a stable environment in the tanning cylinder 120, and at the same time effectively preventing external impurities or air from entering the tanning cylinder 120, interfering with the chemical process, and affecting the final quality of the leather. By starting the servo motor 210, the first piston rod 280 slides inside the first piston cylinder 290, so that the straw 2940 draws liquid from the tanning cylinder 120, and the liquid enters the storage box 2930 through the straw 2940. When entering the storage box 2930, it will pass through the filter 299 3. The filter 2993 can effectively filter the residue in the liquid, and finally spray it out from the nozzle 2911 and re-enter the tanning cylinder 120 to process the cowhide, which can effectively improve the tanning effect of the cowhide. At the same time, by recycling the tanning liquid, the consumption of water and tanning agent can be reduced, thereby reducing production costs. Circulating filtration can also extend the service life of the tanning liquid, thereby improving resource utilization efficiency. When too much residue is adsorbed on the surface of the filter 2993, the servo motor 210 is reversed to make the scraper 2992 clean the residue adsorbed on the surface of the filter 2993, and the residue falls into the empty groove 2995. By cleaning the filter 2993, the processing efficiency of the cowhide can be further improved. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
