The two first guide rods 16 are slidably provided with a scraper 21, and both ends of the scraper 21 are connected to the connecting rod 19. The second guide rod 17 is sleeved with a second elastic member 22 for resetting the connecting seat 18. The two ends of the second elastic member 22 are respectively connected to the connecting seat 18 and the second guide rod 17.

A protective shell 40 is provided on the right side of the positioning frame 501, and the protective shell 40 protects the second pulley group 8.

[0031] When leather needs to be processed, the leather is first placed on the first conveyor belt 4, and then wound on the second conveyor belt 7. Subsequently, the connecting seat 18 is moved to the side close to each other, and the second elastic member 22 is stretched accordingly, so that the connecting rod 19 rotates outward, and then the connecting plate 20 and the scraper 21 move to the side away from each other, and then the scraper 21 contacts the leather. When the leather is conveyed, the wrinkles on the surface of the leather are scraped flat, so as to prevent the wrinkles from affecting the leather processing effect. Then the pin 23 is inserted into the second guide rod 17 to limit the connecting seat 18, and then the control box 101 is operated to turn on the motor 2. The output shaft of the motor 2 rotates to drive the first drive roller 3 to rotate and convey the leather backward. The first drive roller 3 rotates through The first pulley group 5 rotates the second driving roller 6, and the rotation of the second driving roller 6 rotates the rear rotating rod 9 through the second pulley, and then the third pulley group 10 transmits the power to make the two rotating rods 9 rotate at the same time. The rotation of the rotating rod 9 causes the cam 11 to rotate downward and squeeze the sliding frame 13 to move downward, and the second elastic member 22 is compressed accordingly, so that the sliding frame 13 moves downward and drives the pressing plate 14 to move downward, thereby vibrating and squeezing the leather, thereby loosening the leather fiber tissue and improving the flatness of the leather. When the cam 11 no longer squeezes the sliding frame 13, the second elastic member 22 returns to its original state to move the sliding frame 13 upward and reset. When the leather is transported to the top of the second conveyor belt 7, the softener is sprayed on the leather to improve the softness.

[0032] Example 2: Based on Example 1, please refer to Figure 1 , Figure 7 and Figure 8 A mounting frame 24 is fixedly connected to the front side of the mounting seat 1, and two third driving rollers 26 are rotatably arranged on the mounting frame 24. The third driving roller 26 on the rear side and the first driving roller 3 on the front side are jointly covered with a fourth pulley set 25, and the two third driving rollers 26 are jointly covered with a third conveyor belt 27.

[0033] When the stretching machine is needed, the motor 2 is turned on, the leather is placed on the third conveyor belt 27, the first driving roller 3 on the front side rotates to make the fourth pulley set 25, and the fourth pulley set 25 drives the third driving roller 26 to rotate, and then the leather is conveyed backward to the first conveyor belt 4, so as to achieve the purpose of automatic loading.

[0034] See also Figure 1 and Figure 8A material collecting box 28 is provided on the mounting seat 1 by means of bolt connection, and push blocks 30 are provided on both sides of the third conveyor belt 27. Third guide rods 32 are fixedly connected to the left and right sides of the material collecting box 28, and a material blocking plate 29 is slidably provided on the two third guide rods 32. A connecting frame 31 is fixedly connected to the left and right sides of the material blocking plate 29, and the push block 30 can contact the connecting frame 31. A third elastic member 33 is sleeved on the third guide rod 32, and a protective cover 39 is covered on the material collecting box 28. When the material collecting box 28 is not needed, the protective cover 39 is covered on the material collecting box 28 to prevent dust and other impurities from falling into the material collecting box 28.

[0035] Before processing the leather, the leather is first placed in the collection box 28. When the leather is processed through the control box 101, the third conveyor belt 27 rotates to drive the push block 30 to move backward, so that the push block 30 squeezes the connecting frame 31 and moves backward, thereby driving the blocking plate 29 to move backward to open the collection box 28. The third elastic is stretched accordingly, and the leather falls on the third conveyor belt 27. When the push block 30 no longer squeezes the connecting frame 31, the third elastic returns to its original state and drives the blocking plate 29 to move forward to close the collection box 28, thereby achieving the purpose of intermittent unloading and avoiding leather stacking.

[0036] See also Fig. 9 and Fig.10 A water tank 34 is arranged inside the mounting base 1, and a screw cover 35 is rotatably arranged on the front side of the water tank 34. When softener needs to be added, the screw cover 35 is rotated to open the water tank 34. The right side of the water tank 34 is connected and communicated with an infusion tube 37. A water pump 36 is arranged on the right side of the mounting base 1 by bolt connection. The infusion tube 37 passes through the water pump 36. One end of the infusion tube 37 is fixed on the positioning frame 501, and a plurality of nozzles 38 are connected to the infusion tube 37.

[0037] After the leather is flattened, it is wound above the second conveyor belt 7, and the water pump 36 is turned on. The water pump 36 pumps the softener prepared in the water tank 34 into the infusion tube 37, and then sprays it evenly on the leather through the nozzle 38, so there is no need to spray the softener separately. The leather is softened under the action of the softener, thereby improving the softness of the leather.
