Therefore, the material pressing device can be suitable for arc-shaped materials 30, when the middle material pressing piece 2332 presses the materials 30, the deformation of the materials 30 can be avoided on one hand, on the other hand, certain pressure can be provided for the materials 30, and the loosening of the materials 30 between the moving process and the middle material pressing piece 2332 is avoided.

Further, the intermediate swage 2332 includes an elastic swage for contacting the material. So, when material is pushed down to material spare in the middle of, press material portion and material contact by elasticity, and elasticity presses material portion to have the cushioning effect, can avoid the material to be pressed the deformation to a certain extent.

Specifically, the elastic swage is a rubber pad disposed at the bottommost portion of the middle swage 2332.

As shown in fig. 1 to 9, when the pushing device is used, the pressing member 1317 is first located at a position capable of avoiding the material 30 under the action of the deflection driving member 1314, then the material 30 is put onto the carrying portion 111 from above, at this time, the material 30 is located at the initial position, then the deflection driving member 1314 drives the pressing member 1317 to rotate above the material 30, then the pressing driving member 1312 drives the pressing member 1317 to press the material, and then the first pushing driving member 132 drives the pressing member 1317 to push the material 30, so that the material 30 moves from the initial position toward the middle position. In the process of pushing the material 30 by the pushing assembly 13, on the one hand, the two guiding units 12 can provide guiding function for the material 30, and on the other hand, when the material 30 moves on the bearing part 111, because the left side and the right side of the material 30 are respectively contacted with the two guiding units 12, the material 30 can ensure the accuracy of the posture of the left direction and the right direction under the action of the two guiding units 12, and the material 30 can not generate deviation in the left direction and the right direction. In this way, the first pushing mechanism 10 is utilized to push the material, so that the accuracy of the posture of the material 30 can be ensured, the material 30 is prevented from being processed into a defective product due to deviation of the material 30 in the left and right directions during sewing, and the reliability is high.

After the material 30 moves to the middle position, the first lifting driving member 2311 may drive the front-side limiting member 2312 to descend first, so that the front-side limiting member 2312 limits the front side of the material 30 first, then the second lifting driving member 2321 drives the rear-side limiting member 2322 to descend, so that the rear-side limiting member 2322 limits the rear side of the material 30, at this time, the material 30 is limited between the front-side limiting member 2312 and the rear-side limiting member 2322, and then the third lifting driving member 2331 drives the middle pressing member 2332 to descend again, so that the middle pressing member 2332 compresses the material. The second pusher drive 22 is then able to move the material 30 from the intermediate position to the sewing position when activated. The second pushing mechanism 20 can limit the front and rear sides of the material 30 by using the front limiting piece 2312 and the rear limiting piece 2322, so as to ensure the accuracy of the posture of the material 30 in the front and rear directions, and avoid the material 30 from being processed into a defective product due to the deviation of the material in the front and rear directions during sewing, and the reliability is high.
