[0056] Periodically inject high pressure and high temperature steam, push the leather at the entrance, the steam can keep the leather wet and help to push, while enhancing the activity of the enzyme, to avoid the leather dry and hard; start the external power component 8, with the help of the rolling and stretching component 11 to press and stretch the surface of the leather, physically stretch the leather fiber, make it more soft and elastic, improve the hand feeling; after completing a single pressing and stretching, control the top plate 25 to move along the driven shaft 15, change the extrusion depth of the rolling piece 19, adjust the depth to adapt to different leather thickness, ensure uniform treatment, prevent local damage, and also can re-deliver the leather after single mechanical rolling and stretching, for higher strength rolling and stretching; continue the above process until the leather is completely softened and taken out, repeat the operation to ensure complete softening, and take out the leather in time after completion, which is convenient for next step processing or storage.

[0057] In this embodiment, the pushing mechanism 10 includes a pressure plate 29, a spring sleeve 30, a turnover plate 34 and a clamping plate 35;

[0058] The end of the clamping plate 35 is integrally formed with an air guide hole 36, the top of the clamping plate 35 is integrally formed with a turnover plate 34, the pressure plate 29 is embedded in the inside of the air inlet chamber 27, the bottom end of the air inlet chamber 27 is provided with a strip-shaped hole, the top end of the turnover plate 34 is provided with a lifting plate 31, and the turnover plate 34 and the lifting plate 31 are movably connected through a rotating column 32;

[0059] The two ends of the rotating column 32 are sleeved with torsional springs 33, one end of the torsional spring 33 is fixedly connected with the end of the lifting plate 31, and the other end of the torsional spring 33 is fixedly connected with the side of the turnover plate 34.

[0063] The pushing mechanism 10 periodically applies a pushing force to the leather transported inside the feeding channel 4, which reduces the probability of the leather being stuck in the feeding channel 4 during the transportation into the box 1, and the process can be realized without additional power equipment, which improves the utilization of steam, reduces the equipment cost, and enhances the stability of the equipment operation.

[0064] Specifically, the high-temperature and high-pressure steam generated by the external steam generating device is transported into the air inlet chamber 27 through the pipeline and the channel inside the feeding plate 3 by means of the air pump 7, and the high-temperature and high-pressure steam in the air inlet chamber 27 flows out from the side air injection holes 28 and the circular holes on the bottom lifting plate 31, respectively.

[0065] Since the number and size of the air injection holes 28 are small, the high-pressure state inside the air inlet chamber 27 also acts on the surface of the pressure-bearing plate 29, and the pressure-bearing plate 29 is pressed and pushed as a whole towards the bottom until the entire pushing mechanism 10 moves downward, and during the movement, the torsional spring 33 always pulls the turnover plate 34 and the clamping plate 35 on the bottom towards the inside, so that the clamping plate 35 directly acts on the side of the leather.

[0066] With the continuous downward movement of the pushing mechanism 10 and the clamping effect on the leather, the leather can be directly pushed downward, and the entire leather is finally pulled downward, so that even if the leather is stuck during the entry process, the clamping plate 35 can play a certain role in dredging during the process of being pushed towards the bottom, and this process relies on the periodic start of the air pump 7.

[0072] The sponge strip is used for absorbing high-temperature steam, and the leather to be processed passes downwards from the gap between the rolling roller 12 and the pressure roller 13.

[0073] Specifically, after the starting motor 9 is started, the driving shaft 14 is driven to rotate by the motor 9, the driving shaft 14 drives the driven gear 17 to rotate through the driving gear 16 on the surface, so as to directly drive the rolling roller 12 and the pressure roller 13 at the end to rotate, at this time, the leather transported at the top passes through the gap between the rolling roller 12 and the pressure roller 13, and when passing through, the rolling part 19 applies a pushing force to the side edge of the leather from one side, and finally the rolling effect is used to achieve the softening purpose of the leather.

[0074] The high-temperature and high-pressure steam on the pressure plate 29 passes through the round hole on the surface of the pressure plate 29 through the hollow structure on the inside of the pushing mechanism 10 at the top, and then enters the inside of the lifting plate 31 at the bottom along the spring sleeve 30, and finally is transported to the air guide hole 36 at the end along the plate at the bottom, and is sprayed to the surface of the rolling roller 12 and the pressure roller 13, so that the surface of the rolling roller 12 and the pressure roller 13 can also have high-temperature moisture.

[0075] In the embodiment, the rolling part 19 comprises a plug-in plate 21, a rolling plate 20 and an inclined plate 23, the bottom of the rolling plate 20 is integrally formed with the plug-in plate 21, the plug-in plate 21 is used for penetrating the surface of the rolling roller 12, and the end of the plug-in plate 21 is provided with the inclined plate 23.

[0078] The abutting disc 25 is used for simultaneously contacting the bottom of each rolling part 19, and the abutting disc 25 is used for pushing each rolling plate 20 outward.

[0079] With the help of the pushing mechanism 10, part of the steam can also be transported towards the position of the rolling and stretching assembly 11 at the bottom, so that high-temperature steam can also adhere to the surface of the two rollers and the inside of the sponge strip, further providing the influence of high-temperature steam during mechanical processing, improving the softening effect, and also cooperating with the movement of the inside abutting disc 25 to regulate the strength of the rolling and stretching, expanding the application range.

[0080] Specifically, the spring rod 22 can always exert a downward pulling force on the plug-in plate 21, and by pushing the locking sleeve 24, the abutting disc 25 can be directly driven to move along the driven shaft 15. With the edge of the abutting disc 25 contacting the surface of the inclined plate 23, the abutting of the entire rolling part 19 is realized, and the spring rod 22 is stretched until the outer rolling plate 20 is pushed outwards, changing the extension length of the rolling plate 20, which can change the depth of the leather pushed into the groove 18 by the rolling plate 20, thereby achieving the purpose of regulating and changing the stretching strength.
