[0023] See also Figure 1-4 The utility model provides an embodiment: a leather production flattening device, comprising a bottom plate 1, a frame 2 is fixedly installed on the upper surface of the bottom plate 1, two sets of bearing seats 3 are fixedly installed on both sides of the front end of the frame 2, and one end of the bearing seat 3 of the frame 2 is a feeding end for leather flattening;

[0024] A screw rod 4 is connected between two horizontally opposite bearing seats 3, and a moving member 5 is threadedly connected to the two screw rods 4. The two sets of moving members 5 are horizontally mirrored (i.e., relatively arranged, for details, please refer to the attached manual). Figure 1As shown), a cleaning brush plate 9 is fixedly installed on the outer wall of the opposite side of the moving part 5, and a dust removal brush 10 is fixedly installed on the outer wall of the cleaning brush plate 9. In order to provide rotational power for the screw rod 4, one end of the two screw rods 4 passes through the bearing seat 3 and is fixedly connected to the output shaft of the motor 8. The motor 8 can be a servo motor, so that the number of rotations and the direction of rotation can be conveniently controlled by servo, thereby improving the comprehensive control effect;

[0025] Furthermore, in order to limit and guide the moving member 5 and prevent the moving member 5 from rotating synchronously with the screw rod 4, a limit slot 6 is provided at the front end of the frame 2, and a limit block 7 is fixedly installed on the outer wall of the moving member 5 close to the limit slot 6. The limit block 7 is inserted into the limit slot 6, and the two are slidably connected.

[0026] In this structural design, the limit block 7 can be used to limit the moving part 5, thereby effectively preventing the moving part 5 from rotating with the screw rod 4. The cooperation of the limit block 7 and the limit groove 6 can make the moving part 5 have a certain limit displacement guiding effect, thereby ensuring the normal movement of the moving part 5.

[0027] In addition, the overall comprehensive working principle of the above structure is described as follows:

[0028] Please refer to the instruction manual for details. Figure 1 , Figure 2 and Figure 3 It is understood that when the leather enters through the feed end of the flattening device, the upper and lower surfaces of the leather will be placed between the two sets of cleaning brush plates 9, and the upper and lower outer surfaces of the leather will be in full contact with the dust removal brushes 10 of the cleaning brush plates 9;

[0029] At this time, the two sets of motors 8 can perform forward and reverse rotation. When the motor 8 is working, it will drive the screw rod 4 to rotate synchronously through the output shaft. When the screw rod 4 is rotating, the movable part 5 threaded thereon will move left and right, thereby driving the cleaning brush plate 9 and the dust removal brush 10 below it to move back and forth through the left and right movement of the movable part 5. When the dust removal brush 10 moves back and forth left and right, it will remove dust and clean the outer surface of the leather, thereby removing small particles remaining on the outer surface of the leather, thereby effectively preventing particles from adhering to the outer surface of the leather, increasing the production quality of subsequent feeding and flattening, and effectively avoiding damage to the leather surface caused by particles during flattening, thereby increasing the flattening quality and aesthetics of the leather.

[0030] In this embodiment, lower roller frames 11 are fixedly installed on both sides of the bottom end of the frame 2, and lower flattening rollers 12 are rotatably installed on the two lower roller frames 11;

[0031] Furthermore, a first-stage upper plate 15 is fixedly installed on both sides above the frame 2, and the first-stage upper plate 15 and the lower roller frame 11 are in the same vertical horizontal plane, and a total of four first-stage cylinders 16 are fixedly installed on the two sets of first-stage upper plates 15;

[0032] An upper roller frame 17 is fixedly installed between the output rods of the first-stage cylinder 16 of the same first-stage upper plate 15, and an upper flattening roller 18 is rotatably installed in the upper roller frame 17;

[0033] This structural design can roll and flatten the leather after feeding through the two sets of lower flattening rollers 12 and upper flattening rollers 18, thereby ensuring normal flattening use.

[0034] In this embodiment, a support frame 13 is provided between the two groups of lower roller frames 11, the support frame 13 is fixedly connected to the frame 2, and a lower pressing plate 14 is fixedly installed on the top of the support frame 13;

[0035] Furthermore, a secondary upper plate 19 is provided between the two groups of primary upper plates 15, a secondary cylinder 20 is fixedly installed on the upper surface of the secondary upper plate 19, and an upper pressure plate 21 is fixedly installed between the bottom ends of the output rods of the two secondary cylinders 20;

[0036] Similarly, by arranging two upper and lower pressing plates between the two sets of pressing rollers, the pressing plates are used in conjunction with the pressing rollers, thereby further improving the pressing and wrinkle-removing effect of the leather, and having better pressing performance and pressing production quality;

[0037] The upper roller body and the upper pressing plate 21 can be raised and lowered by a number of groups of cylinders. In actual use, this structure can be suitable for flattening production of leathers of different thicknesses by adjusting the distance between the symmetrical flattening structures, thereby increasing the size range of use and reducing the limitations of the use of this equipment. The spacing can also be adjusted to dynamically adjust the pressure exerted on the leather during flattening, thereby effectively improving the flattening quality. At the same time, this structure is suitable for flattening different types of leather and has good performance.

[0038] Working principle:

[0039] Please refer to the attached manual for details Figure 1-4 When in use, the leather enters the flattening device through the feed end. After the leather enters through the feed end of the flattening device, the upper and lower surfaces of the leather will be placed between the two sets of cleaning brush plates 9, and the upper and lower outer surfaces will be in full contact with the dust removal brushes 10 of the cleaning brush plates 9;

[0040] At this time, the two motors 8 can be set to work in forward and reverse directions. When the motor 8 is working, it will drive the screw rod 4 to rotate synchronously through the output shaft. When the screw rod 4 is rotating, the moving member 5 threaded thereon will move left and right, thereby driving the cleaning brush plate 9 and the dust removal brush 10 below it to move back and forth through the left and right movement of the moving member 5. When the dust removal brush 10 moves back and forth, it will remove dust from the outer surface of the leather, thereby removing small particles remaining on the outer surface of the leather, thereby effectively preventing particles from adhering to the outer surface of the leather, increasing the production quality of subsequent feeding and flattening, and effectively avoiding damage to the leather surface caused by particles during flattening, thereby increasing the flattening quality and aesthetics of the leather;

[0041] Driven by the external winding device, the leather passes through the flattening roller at the front end, the flattening plate in the middle and the flattening roller at the rear end in sequence. The two sets of lower flattening rollers 12 and upper flattening rollers 18 can roll and flatten the leather after feeding to ensure normal flattening use.

[0042] Similarly, by arranging two upper and lower pressing plates between the two sets of pressing rollers, the pressing plates are used in conjunction with the pressing rollers, thereby further improving the pressing and wrinkle-removing effect of the leather, and having better pressing performance and pressing production quality;

[0043] The upper roller body and the upper pressing plate 21 can be raised and lowered by a number of groups of cylinders. In actual use, this structure can be suitable for flattening production of leathers of different thicknesses by adjusting the distance between the symmetrical flattening structures, thereby increasing the size range of use and reducing the limitations of the use of this equipment. The spacing can also be adjusted to dynamically adjust the pressure exerted on the leather during flattening, thereby effectively improving the flattening quality. At the same time, this structure is suitable for flattening different types of leather and has good performance.

[0044] In summary, the leather flattening device of the utility model is provided with a particle cleaning structure at the feeding end of the flattening device, and the particle cleaning structure removes dust and cleans the outer surface of the leather through a screw transmission, so that the small particles remaining on the outer surface of the leather can be removed, thereby effectively preventing the particles from adhering to the outer surface of the leather, increasing the production quality of subsequent feeding and flattening, and effectively avoiding the particles from damaging the leather surface during flattening, thereby increasing the flattening quality and aesthetics of the leather;

[0045] The utility model can be used for flattening leather of different thicknesses by adjusting the spacing between the flattening symmetrical structures, thereby increasing the size range of use and reducing the limitations of the use of the equipment. The spacing can also be adjusted to dynamically adjust the pressure applied to the leather during flattening, thereby effectively improving the flattening quality. The utility model is also suitable for flattening different types of leather and has excellent performance.
