DETAILED DESCRIPTION

[0022] The following will be combined with the drawings Figures 1-3 The specific implementation of the utility model is further explained in detail.

[0023] As Figures 1-3 Shown, the utility model discloses a leather skin polishing and leveling machine, including fixed unit 10, be used to the collection and pay off the winding unit 20 of leather, be used to the pressure unit 30 of leather in the leveling and be used to the polishing unit 40 of leather in the process of winding and pay off, and be used to the leveling unit 50 of leather.

[0024] Specifically, the unwinding and winding unit 20 comprises unwinding rollers 21 and winding rollers 22 rotatably installed at both ends of the fixed unit 10 for unwinding and winding the leather 60, the pressing unit 30 comprises two sets of pressing plates 31 movably arranged between the unwinding rollers 21 and the winding rollers 22 for pressing the leather 60 on the surface of the fixed unit 10, the polishing unit 40 comprises a polishing press wheel 41 rotatably arranged on the surface of the fixed unit 10 for polishing the surface of the leather 60, and the flattening unit 50 comprises a flattening press roller 51, a telescopic cylinder structure 53 connected with the flattening press roller 51 for driving the flattening press roller 51 to move in the vertical direction, and a driving mechanism 52 arranged above the fixed unit 10 for driving the telescopic cylinder structure 53 to move back and forth.

[0025] In use, the leather 60 to be polished and flattened is wound on the unwinding rollers 21, and then the other end of the leather 60 is connected with the winding rollers 22 after passing through the bottom of the polishing press wheel 41, the pressing plates 31 and the flattening press roller 51. When the winding rollers 22 rotate, the leather 60 is moved from the unwinding rollers 21 to the winding rollers 22. During the movement, the polishing press wheel 41 rotates to rub against the surface of the leather 60 to polish the surface of the leather 60. After moving a certain distance, the winding rollers 22 stop rotating, the pressing plates 31 press the leather 60 on the surface of the fixed unit 10, the telescopic cylinder structure 53 is extended to press the flattening press roller 51 on the surface of the leather 60, and then the driving mechanism 52 drives the flattening press roller 51 to move back and forth on the surface of the leather 60. During the pressing process, the two ends of the leather 60 are kept pressed by the pressing plates 31. After the pressing is completed, the telescopic cylinder structure 53 is extended, and the pressing plates 31 are loosened. Then the winding rollers 22 repeat the winding operation. In this way, the flattening press roller 51 can ensure the pressing force on the surface of the leather 60, and the leather 60 can be prevented from being subjected to excessive tension when being wound.

When the flattening roller 51 fluctuates, the spring 58 is stretched and contracted, so that the pressure value detected by the pressure sensor 57 is changed constantly. The greater the change range of the pressure value is, the greater the wrinkle on the surface of the leather 60 is. The rolling needs to be continued. When the pressure value detected by the pressure sensor 57 tends to be stable, it is indicated that the surface of the leather 60 is relatively flat, so that the flattening process is stopped. The next piece of leather 60 is sent to the surface of the fixed unit 10 for leather buffing and flattening treatment through the winding roller 22.

[0028] The surface of the fixed unit 10 is fixedly provided with a pressing cylinder 32, the pressing plate 31 is fixedly connected with the telescopic end of the pressing cylinder 32, and the pressing cylinder 32 drives the pressing plate 31 to move in the vertical direction.

After the winding and unwinding process is completed, the pressing plate 31 can be pressed against the leather 60 through the elongation of the pressing cylinder 32 during the flattening process, so that the leather 60 can be prevented from being twisted during the flattening process.

[0029] The surface of the fixed unit 10 is fixedly provided with a first motor 42, the output shaft of the first motor 42 is fixedly connected with the rotating shaft of the buffing roller 41, the moving direction of the leather 60 is from the unwinding roller 21 to the winding roller 22, the first motor 42 can drive the buffing roller 41 to move in the direction opposite to the moving direction of the leather 60, the buffing roller 41 and the leather 60 are rubbed against each other to realize the leather buffing, and in addition, the buffing roller 41 can guide the movement of the leather 60, so that the leather 60 can be kept on the surface of the fixed unit 10.

[0030] The surface of the fixed unit 10 is fixedly provided with a second motor 23, the output shaft of the second motor 23 is fixedly connected with the rotating shaft of the winding roller 22, and the second motor 23 is used for driving the winding roller 22 to rotate, so that the leather 60 is wound through the rotation of the winding roller 22.

[0031] Please refer to Figure 2 The surface of the fixed unit 10 is embeddedly installed with an electric heating plate 70, the leather 60 is heated through the electric heating plate 70, so that the flattening roller 51 can be ironed when rolling.
