[0019] In summary, the present utility model has the following beneficial effects:

[0020] 1. The utility model drives a bidirectional lead screw to rotate through a motor, so that two moving plates threadedly connected thereto can be driven to move towards each other. By utilizing the hinge action between the moving plate, the sewing table and the adjusting rod, the sewing table can be pushed to move vertically upward. When the leather fabric on the top of the sewing table contacts the flattening roller, due to the continuous upward movement of the sewing table, and under the sliding fit between the slider and the slide rod, the hinge fit between the slider, the connecting rod and the link, and the hinge fit between the connecting rod and the bracket, two flattening rollers can be pushed to roll away from each other on the top of the sewing table, so that the arched leather fabric can be straightened and flattened, effectively avoiding the problem that the sewing of the leather fabric is affected because it is difficult to flatten the unrolled leather fabric.

[0021] 2. During the movement of the slider, the utility model can also drive the brush plate to move together, so that the impurities and dust on the surface of the leather fabric can be swept away, thereby ensuring the sewing quality of the leather fabric. Since the height of the sewing table is continuously rising, through the telescopic action of the telescopic rod, while ensuring the smooth movement of the brush plate, the upward movement of the sewing table will not be hindered.

The bottom of the processing table 1 is also fixedly connected with a motor and the end of the rotor of the motor is coaxially and fixedly connected to the bidirectional lead screw 3. Both sides of the outside of the bidirectional lead screw 3 are threadedly connected with moving plates 4. Between the moving plates 4 and the sewing table 2, there is an adjusting rod 5 hinged through a hinge member, which is convenient for adjusting the vertical height of the sewing table 2. Both sides of the bidirectional lead screw 3 are fixedly connected with guide rods 6 and the guide rods 6 are slidably connected with the moving plates 4, which can play a certain guiding role in the horizontal movement of the moving plates 4. The processing table 1 is symmetrically provided with strip-shaped through grooves, which are convenient for the adjusting rod 5 to move;

[0032] A leveling assembly. The leveling assembly includes a bracket 101 fixedly connected to the top of the processing table 1. Above the sewing table 2, there are symmetrically arranged connecting seats. On the connecting seats, there is a leveling roller 102 rotatably connected. The bottoms of the two groups of leveling rollers 102 are on the same horizontal line. The connecting seats are fixedly connected with connecting rods 103 and the connecting rods 103 are hinged to the bracket 101 through hinge members. On both sides of the lower surface of the bracket 101, there are symmetrically fixedly connected with slide rods 104 through fixed seats. The outside of the slide rods 104 is slidably connected with sliders 105. Between the sliders 105 and the connecting rods 103 on the same side, there is a connecting rod 106 hinged through a hinge member. The outside of the slide rods 104 is sleeved with a first spring 107. The two ends of the first spring 107 are respectively fixedly connected with the fixed seat and the slider 105.

[0033] The bottom of the slider 105 is fixedly connected with a telescopic rod 201. The bottoms of the two groups of telescopic rods 201 on the same side are fixedly connected with the same brush plate 202. The outside of the telescopic rod 201 is sleeved with a second spring 203. The two ends of the second spring 203 are respectively fixedly connected with the slider 105 and the brush plate 202. The telescopic rod 201 is a prior art and is composed of a sleeve and a rod that is movably connected to the inside of the sleeve at one end.

[0034] In the embodiment of the present application, the implementation principle of a seat leather sewing device is as follows: First, place the unrolled leather fabric on the sewing table 2, then start the motor, drive the bidirectional lead screw 3 to rotate through the motor, so that two moving plates 4 threadedly connected thereto can be driven to move towards each other. By the hinged action between the moving plate 4, the sewing table 2 and the adjusting rod 5, the sewing table 2 can be pushed to move vertically upward. When the leather fabric on the top of the sewing table 2 contacts the flattening roller 102, due to the continuous upward movement of the sewing table 2, and under the sliding fit between the slider 105 and the slide bar 104, the hinged fit between the slider 105, the connecting rod 103 and the connecting rod 106, and the hinged fit between the connecting rod 103 and the bracket 101, two flattening rollers 102 can be pushed to roll away from each other on the top of the sewing table 2, so that the arched leather fabric can be straightened and flattened, with strong practicability. When the sewing table 2 rises to the highest position, the two flattening rollers 102 are just located on both sides of the top of the sewing table 2. At the same time, during the movement of the slider 105, the brush plate 202 can also be driven to move together, so that the impurities and dust on the surface of the leather fabric can be swept away, thereby ensuring the sewing quality of the leather fabric. Since the height of the sewing table 2 is continuously rising, through the telescopic action of the telescopic rod 201, while ensuring that the brush plate 202 can move smoothly, it will not hinder the upward movement of the sewing table 2, further improving the practicability of the device. A sewing device for sewing the leather fabric can be installed on the top of the bracket 101. Subsequently, after sewing is completed, control the motor to reverse to drive the sewing table 2 to move vertically downward. By the elastic return action of the first spring 107 and the second spring 203, the flattening roller 102 and the brush plate 202 can be automatically reset. Finally, take away the sewn leather fabric.

[0035] In addition, a further improvement is that guide rollers 7 are rotatably connected to both sides of the sewing table 2, which can prevent the leather fabric from being scratched due to friction with the edge of the sewing table 2.
