[0068] like Figure 1-7As shown, this embodiment also provides a method for making leather using a health-preserving leather making device, comprising the following steps:

[0069] Step 1: Leather pre-treatment steps

[0070] The operator immerses the untreated raw hide in a fresh water pool for more than 2 hours to release the sewage inside, then takes out the soaked raw hide, and performs dehairing after low-temperature drying at 60°C to 70°C to obtain dehaired leather, and sprays an enzyme treatment liquid on the surface of the dehaired leather. The enzyme treatment liquid is a mixture of 40U / g lipase JZ, 20U / g protease JRH and 4U / g saccharifying enzyme TH to obtain degreased leather;

[0071] Step 2: Softening the leather

[0072] 100 parts of casein are added into a reaction tank, dissolved and heated to 80°C, and then 10 parts of borax are added and stirred until the casein is completely dissolved, and then coated on the surface of the degreased leather, and allowed to stand for more than 10 minutes, and then the degreased leather is washed with pure water for more than 2 times, and the washed leather is immersed in a mixed acid solution, which is a mixed solution of 40% sulfone acid polymer and 0.4% formic acid, mixed in a volume ratio of 1:0.5, and the total volume ratio of the mixed acid solution to the degreased leather is 1:0.6, and the leather after pickling is kept for more than 120 minutes, and then the treated leather is sprayed with trypsin at 30°C for 30 minutes, and then the pH value is adjusted to 8.5 by adding NaOH, and the softening time is more than 5 hours to obtain softened leather 4 to be treated;

[0073] Step 3: First processing step

[0074] The operator opens the clamps 51 one by one to clamp and fix the leather 4 to be processed around, then puts the fixing ring 58 on the column of the support frame 7 and fixes it, rotates the adjustment member 54 clockwise to move it toward the middle to tighten the leather 4 to be processed into a taut state, and after the leather 4 to be processed is tightened around, the support frame 7 with the leather 4 to be processed in a taut state is placed on the tooling frame 2 and fixed; turns on the equipment switch, and the conveying device 1 starts to send the leather 4 to be processed into the middle position in the first processing chamber 12, and opens the valves on the first upper spray group 124 and the first lower spray group 125 The door is switched on and off, and high-pressure compressed air is ejected and carries the quartz sand in the first material tank 11 to sandblast the leather 4 to be treated. The injection pressure range of the material ejected by the first injection head 123 is 6-8 MPa. The conveying device 1 moves the leather 4 to be treated back and forth between the first upper injection group 124 and the first lower injection group 125 at a uniform speed, and the reciprocating frequency is 2 times / minute. The sandblasting time is 5-10 minutes. When the sandblasting time is reached, the control system is operated to allow the conveying device 1 to send out the leather that has been sandblasted to obtain the treated leather 4 after initial sandblasting.

[0075] Step 4: Second processing step

[0076] The operator adjusts the initially sandblasted leather 4 obtained at the front end of the second processing chamber 12, rotates the adjustment member 54 counterclockwise to move it to both ends, so that the initially sandblasted leather 4 is in a relaxed drooping state, turns on the equipment switch, and the conveying device 1 delivers the initially sandblasted leather 4 to the middle position in the second processing chamber 22, opens the valves of the second upper injection group 224 and the second lower injection group 225, and the high-pressure air is ejected to carry the quartz sand in the second material tank 21 to perform sandblasting tanning on the initially sandblasted leather 4, and the second injection head 223 ejects the injection pressure of the material. The force range is 8-10MPa. At this time, the second upper jet group 224 and the second lower jet group 225, which are staggered at the upper and lower positions, will make the initial sandblasted leather 4 form a wave-breaking shape with different heights at the upper and lower positions for tanning treatment. The conveying device 1 will make the initial sandblasted leather 4 move back and forth at a uniform speed between the second upper jet group 224 and the second lower jet group 225. The reciprocating frequency is 1 time / minute, and the treatment time range is 20-30 minutes. After the sandblasting treatment time is reached, the conveying device 1 will send out the leather 4 that has completed the tanning and sandblasting treatment to obtain soft leather 4;

[0077] In this embodiment, in order to speed up the tanning frequency and improve the tanning quality of the tanned leather 4, the second lower jet group 225 works at intervals. After an interval of 5 seconds, the control system closes the valve of the second lower jet group 225 to allow the initially sandblasted leather 4 to droop under the action of gravity. After another interval of 5 seconds, the control system opens the valve of the second lower jet group 225 to allow the initially sandblasted leather 4 to be lifted upward. This cycle lasts for 15 minutes, thereby increasing the frequency of tanning leather and improving the quality of the tanned leather 4.

[0078] Step 5: Third processing step

[0079] After the operator takes the obtained soft leather 4 at the front end of the third processing chamber 32, it is placed on the circular working table 8, and the clamps 51 are opened one by one to clamp the four sides of the soft leather 4, and then the fixing ring 58 is firmly fixed to the column of the working table 8, and the equipment switch is turned on, and the working table 8 with the fixed soft leather 4 is sent to the middle position in the third processing chamber 22 by using the conveying device 1, and the first heating plate 9 on the lower side of the working table 8 is turned on for preheating, and the preheating temperature is 40°C to 50° to facilitate the curing of the adhesive and sand particles, wherein the adhesive is selected from sodium methyl silicate and potassium methyl silicate, and the valve switches of the third air supply pipe 322, the third feed pipe 321 and the fourth feed pipe 324 are opened, and the control system sends compressed air and the circular storage in the third material tank 21 to the third material tank 21. The shaped quartz sand and the adhesive in the fourth material tank 34 are evenly sprayed onto the surface of the soft leather 4 to form a mixture layer. The compressed air sprays the quartz sand and the adhesive from the third injection head 323 to form a crust layer with more than one layer of sand on the leather 4 to be processed on the work surface 8. The compressed air increases the surface area of ​​the sand and the adhesive to fully bond. The conveying device 1 moves the shell leather 4 with a layer of shell at a uniform speed under multiple third injection heads 323. The reciprocating frequency is 1 time / minute, and the time range is 3 to 5 minutes. After the required crust thickness is reached, the conveying device 1 sends out the leather 4 with the shell. After the operator removes the solid shell, it is washed with clean water for more than 30 minutes to obtain a clean leather 4.

[0080] Step 6: Turn over the leather 4 with one side cleaned, and repeat the processing steps in step 5 to obtain the leather body of the double-sided cleaned leather 4. Since the gravity of the shell is pressed on the leather 4, the shell plays a role in increasing the density of the leather body, thereby improving the quality of the leather 4;

[0081] Step 7: Grinding of Chinese herbs

[0082] Grind the Chinese herbal medicine composed of gentiana macrophylla, safflower, safflower, white pepper, notopterygium wilfordii, scutellaria baicalensis, phellodendron amurense, saposhnikovia divaricata, angelica pubescens, dried ginger and borneol to obtain Chinese herbal medicine powder, and then mix the Chinese herbal medicine powder and put it into the fifth material tank 41 storing silica gel liquid and stir it evenly to obtain a mixed solution of the Chinese herbal medicine and silica gel liquid;

[0083] Step 8: Fourth processing step

[0084] The operator places the leather body obtained in step 6 on the circular work surface 8, presses open the clamps 51 one by one to clamp the four sides of the leather body, and then firmly fixes the fixing ring 58 to the column of the work surface 8, turns on the equipment switch, and uses the conveying device 1 to send the fixed leather body work surface 8 to the middle position in the fourth processing chamber 42; turns on the switch of the telescopic rod 429 in the equipment, extends the telescopic rod 429 to drive the fourth injection head 423 to move downward, and the needle tip 427 penetrates into the leather body until it reaches three-fifths of the thickness of the leather body, turns off the switch of the telescopic rod 429, and the needle tip 427 stops; turns on the valve switches of the fourth pump group 40 and the fourth air supply pipe 422, and the control system injects compressed air through the injection port 4274 of the first injection channel 4272, and the high-pressure compressed air inflates the space at this position to form an airbag bag; then turns on the fourth feed pipe 421 and the fifth feed pipe 422. The valve switch of the tank 41 is used, and the pressure fills the airbag bag with the mixture of the Chinese herbal medicine and the silicone liquid in the fifth material tank 41 through the injection port 4274 of the second injection channel 4273; the switch of the telescopic rod 429 in the equipment is turned on, and the telescopic rod 429 is retracted to drive the fourth injection head 423 to move upward, so that the needle tip 427 is pulled out from the leather body; the valve switches on the sixth supply tank 44 and the fifth supply pipe 424 are immediately opened, and the catalyst in the sixth supply tank 44 is sprayed out from the spray pipe 430 on the fourth injection head 423. The catalyst accelerates the solidification of the silicone. After standing for 20 minutes, the silicone solidifies. Among them, in order to reduce the overflow of the injected Chinese herbal medicine and silicone liquid mixture from the airbag bag and allow the silicone to solidify quickly, a second heating plate 91 is provided on the lower side of the work surface 8 for heating. The operator opens the clamps one by one, obtains the health-preserving leather body containing the Chinese herbal medicine and the silicone balls, and then transfers it to a warehouse at room temperature for hanging for standby use.

After the sandblasting tanning processing time is reached, the conveying device (1) will send out the leather (4) that has completed the tanning sandblasting processing to obtain the tanned leather (4); Step 5: Third processing step After the operator takes the obtained tanned leather (4) from the front end of the third processing chamber (32), the operator places it on the circular working table (8), presses the clamps (51) one by one to clamp the four sides of the soft leather (4), and then firmly fixes the fixing ring (58) to the column of the working table (8), turns on the equipment switch, uses the conveying device (1) to send the working table (8) with the fixed soft leather (4) into the middle position in the third processing chamber (22), turns on the first heating plate (9) on the lower side of the working table (8) for preheating, and the preheating temperature is 40°C to 50°C to facilitate the curing of the adhesive and sand particles, wherein the adhesive is selected from sodium methyl silicate and potassium methyl silicate, opens the valve switches of the third air supply pipe (322), the third material supply pipe (321) and the fourth material supply pipe (324), and the control system sends compressed air and the third material tank (2 1) The circular quartz sand stored in the fourth material tank (34) and the adhesive in the fourth material tank (34) are uniformly sprayed onto the surface of the soft leather (4) to form a mixture layer. The compressed air sprays the quartz sand and the adhesive from the third spray head (323) onto the leather (4) to be processed on the work surface (8) to form a crust layer with more than one layer of sand. The compressed air increases the surface area of ​​the sand and completely bonds the adhesive. The conveying device (1) moves the leather (4) with one layer of shells at a uniform speed back and forth under the plurality of third spray heads (323). The back and forth frequency is 1 time / minute and the time range is 3 to 5 minutes. After the required crust thickness is reached, the conveying device (1) delivers the leather (4) with the shells. After the operator removes the solid shell, the leather (4) is washed with clean water for more than 30 minutes to obtain a clean leather (4). Step 6: Turn over process Turning the cleaned leather (4) on one side over, repeating the processing steps in step 5, to obtain a leather body of cleaned leather (4) with qualified double sides; Step 7: Grinding of Chinese herbs Grinding a Chinese herbal medicine composed of gentiana macrophylla, safflower, herba scutellariae, white pepper, notopterygium wilfordii, scutellaria baicalensis, phellodendron amurense, saposhnikovia divaricata, angelica pubescens, dried ginger and borneol to obtain a Chinese herbal medicine powder, and then mixing the Chinese herbal medicine powder and putting it into a fifth material tank (41) storing silica gel liquid and stirring it evenly to obtain a mixed solution of the Chinese herbal medicine and silica gel liquid; Step 8: Fourth processing step The operator places the leather body obtained in step 6 on the circular work surface (8), presses the clamps (51) one by one to clamp the leather body on all sides, then firmly fixes the fixing ring (58) to the column of the work surface (8), turns on the device switch, and uses the conveying device (1) to send the fixed leather body work surface (8) into the middle position of the fourth processing chamber (42); turns on the switch of the telescopic rod (429) in the device, extends the telescopic rod (429) to drive the fourth injection head (423) to move downward, and the needle tip (427) penetrates into the leather body until it reaches three-fifths of the thickness of the leather body, turns off the switch of the telescopic rod (429), stops the needle tip (427), turns on the valve switch of the fourth pump group (40) and the fourth air supply pipe (422), and the control system injects compressed air through the injection port (4274) of the first injection channel (4272) Injection, high-pressure compressed air expands the space at this position to form an air bag, then open the valve switch of the fourth feed pipe (421) and the fifth feed tank (41), and fill the air bag with the mixture of Chinese herbal medicine and silicone liquid in the fifth feed tank (41) through the injection port (4274) of the second injection channel (4273), then open the switch of the telescopic rod (429) in the equipment, let the telescopic rod (429) retract to drive the fourth injection head (423) to move upward, let the needle tip (427) be pulled out from the leather body, open the valve switch on the sixth feed tank (44) and the fifth feed pipe (424), and the catalyst in the sixth feed tank (44) is sprayed out from the spray pipe (430) on the fourth injection head (423). After standing for 20 minutes, the silicone solidifies, and the operator opens the clamps one by one to obtain the health-preserving leather body containing Chinese herbal medicine and silicone balls, and transfers it to a warehouse at room temperature for hanging for use.
