The utility model drives the pressing plate and other components to move up and down by the first hydraulic cylinder, which is convenient for leveling leathers of different thicknesses. With the use of the second hydraulic cylinder, the moving plate and the pressing plate and other components are moved left and right, so that the leather surface is evenly leveled. At the same time, with the fixing component, the two sides of the leather are clamped and fixed, which can effectively prevent the leather from moving during the leveling process, thereby affecting the leveling effect of the leather. The device has multiple functions and is easy to use. Through the transmission component, it is convenient to transmit the leveled leather;

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1 - Figure 7 The flattening device for making the leather surface evenly stressed comprises a side plate 1, a conveying assembly 2 and a flattening assembly 3. The inner wall of the side plate 1 is provided with a fixing assembly 4 for fixing the leather.

[0025] The fixing assembly 4 includes a first rotating rod 401, a screw rod 402, a threaded sleeve 403, a slide plate 404, a spring 405, an extrusion block 406, a moving member 407, a second rotating rod 408, a stopper 409, a torsion spring 410, an axle pin 411, a gear 412, an L-shaped rod 413 and a rack 414. The first rotating rod 401 is rotatably arranged on the inner wall of the side plate 1 through a bearing, the screw rod 402 is arranged at one end of the first rotating rod 401, the threaded sleeve 403 is threadedly connected to the screw rod 402 through a threaded hole, the slide plate 404 is slidably arranged on the inner wall of the side plate 1, the spring 405 is arranged on the inner wall of the side plate 1, and one end of the spring 405 is connected to the sliding The plate is fixed, the extrusion block 406 is arranged on one side of the slide plate 404, the moving part 407 is slidably arranged on the inner wall of the side plate 1, the second rotating rod 408 is rotatably arranged on the inner wall of the side plate 1 through a bearing, the limiting part 409 is arranged on the surface of the second rotating rod 408, and the torsion spring 410 is sleeved on the outer wall of the second rotating rod 408. One end of the torsion spring 410 is fixed to the limiting part 409, and the moving part 407 is rotatably connected to the limiting part 409 through an axle pin 411. A gear 412 is arranged on the end of the first rotating rod 401 away from the screw rod 402, an L-shaped rod 413 is arranged at the bottom of the leveling component 3, and a rack 414 is arranged on one side of the L-shaped rod 413.

[0026] Slide blocks 5 are provided on both sides of the slide plate 404, a first slide groove is provided on the inner wall of the side plate 1, and the outer wall of the slide block 5 is slidably connected to the inner wall of the first slide groove, a slide rail 6 is provided on the inner wall of the side plate 1, and a second slide groove is provided at the bottom of the movable member 407, and the movable member 407 is slidably connected to the outer wall of the slide rail 6 through the second slide groove. The setting of the slide rail 6 provides a clear motion trajectory for the movable member 407, which ensures that the movable member 407 will not deviate from the predetermined path when sliding, thereby maintaining the stability and accuracy of the entire mechanism, and the smooth surface of the slide rail 6 helps to reduce the friction resistance of the movable member 407 when sliding, which can not only increase the moving speed of the movable member 407, but also reduce the heat and wear generated by friction, thereby extending the service life of the equipment. The number of the first rotating rods 401 is four, and the number of the screw rods 402 corresponds to the number of the first rotating rods 401.

[0027] A non-slip pad 7 is provided on the side of the limiter 409 close to the transmission component 2 to increase the friction between the limiter 409 and the leather so that the limiter 409 can contact the leather more firmly. The L-shaped strip is symmetrically arranged at the bottom of the leveling component 3, and the rack 414 is arranged on the side of the L-shaped rod 413 close to the gear 412.

[0028] Working principle: When the leather is put on the conveying component 2, and the leveling component 3 is driven to level the leather, the leveling component 3 first descends and contacts the leather. After the leveling component 3 contacts the leather, the leveling component 3 is driven to move forward. At this time, while the leveling component 3 moves forward, the rack 414 on the left side drives the gear 412 on the left side to rotate, and the rotation of the gear 412 drives the first rotating rod 401 to rotate, and the rotation of the first rotating rod 401 drives the screw 402 to rotate, and the rotation of the screw 402 causes the threaded sleeve 403 to rotate downward along the screw 402. When the threaded sleeve 403 moves downward, When the slide plate 404 is rotated and contacts the slide plate 404, the threaded sleeve 403 presses the slide plate 404 downward, and the slide plate 404 slides downward along the inner wall of the side plate 1. At this time, the spring 405 is compressed, and the slide plate 404 slides downward while bringing the extrusion block 406 to squeeze the moving member 407. The moving member 407 is squeezed by the inclined surface of the extrusion block 406 so that the moving member 407 moves to both sides along the slide rail 6. The moving member 407 moves to push the shaft pin 411 to drive the limiting member 409 to rotate toward one side of the transport component. While the limiting member 409 rotates, the torsion spring 410 is compressed, thereby fixing the leather.

[0029] When the leveling component 3 is leveling the leather and moving forward, the leveling component 3 moves with the right rack 414 to contact the right gear 412 and turn the right gear 412 to rotate, the gear 412 rotates to drive the first rotating rod 401 to rotate, and the first rotating rod 401 rotates to drive the screw 402 to rotate, and the screw 402 rotates to make the threaded sleeve 403 rotate upward along the screw 402, and when the threaded sleeve 403 rotates upward until it is no longer in contact with the slide plate 404, the spring 405 recovers its deformation and pushes the slide plate 404 to slide upward along the side plate 1, and the slide plate 404 slides upward while bringing the squeeze The pressing block 406 slides out between the two moving parts 407. At this time, the torsional recovery deformation pulls the two moving parts 407 to slide inward, and while the moving parts 407 slide inward, they pull the axle pin 411 to make the limit part 409 rotate and open in the direction of the side panel 1, so that when the leveling component 3 moves forward, the fixing component 4 fixes the leather at the rear and unlocks the fixing component 4 in the front. When the leveling component moves backward, the fixing component 4 in the front is fixed and the fixing component 4 at the rear is unlocked, thereby avoiding the problem of incomplete extrusion of the leather due to improper position of the limiting component 409.
