One end of the clamp arm 8 away from the rotating shaft 7 passes through the clamp box 4, and an upper clamp body 9 is arranged between the several ends, a lower clamp body 10 corresponding to the upper clamp body 9 is arranged in the clamp box 4, the lower clamp body 10 is hinged to the clamp box 4, a motor bracket 11 is arranged on the clamp box 4, a driving motor 12 is arranged on the motor bracket 11, and the driving motor 12 is connected to one of the clamp arms 8, a linkage mechanism is arranged between the upper clamp body 9 and the lower clamp body 10, and a height adjustment mechanism is arranged between the shearing device 5 and the clamp box 4.

[0024] like Figure 3 As shown, in this example, preferably, a driving plate 13 is provided on the main shaft of the driving motor 12, a bearing roller 14 is eccentrically provided on the driving plate 13, a waist-shaped groove 15 is provided on the clamp arm 8, and the bearing roller 14 slides in the waist-shaped groove 15.

[0025] like Figure 6 and Figure 7 As shown, in this example, preferably, a linkage chain 16 is provided between the upper clamp body 9 and the lower clamp body 10 .

[0026] like Figures 1 to 7 As shown, the operating principle of the clamping type cloth pressing device is: the cloth spreading machine 2 sends the cloth head of the fabric between the upper clamp body 9 and the lower clamp body 10, the driving motor 12 is activated, the driving plate 13 rotates, and the eccentric bearing roller 14 moves in the waist groove 15 of the clamp arm 8, and drives the clamp arm 8 to rotate, thereby driving the upper clamp body 9 to press down on the cloth head, and cooperate with the lower clamp body 10 to clamp the cloth head, and the cloth spreading machine 2 starts the cloth spreading operation;

[0027] When the cloth spreading machine 2 spreads a layer of fabric and cuts it, it sends a release signal to the clamping type cloth pressing device. After the clamping type cloth pressing device receives the signal, the driving motor 12 is activated again to lift the upper clamping body 9, and the lower clamping body 10 is also lifted through the linkage mechanism between the upper clamping body 9 and the lower clamping body 10, so that the cloth head originally clamped falls below the lower clamping body 10;

[0028] At this time, the driving motor 12 continues to move to the upper limit position, so that the upper clamping body 9 and the lower clamping body 10 return to the clamping state, ready to clamp the next layer of cloth.

[0029] Electric cloth clamping is realized without the need for an additional air source and without causing damage to the clamped cloth.

[0030] like Figure 1 and Figure 4 As shown, in this example, preferably, the height adjustment mechanism includes height guide blocks 17 located on both sides of the clamp box 4 and height guide wheels 18 on the shearing device 5, the height guide blocks 17 are provided with height guide grooves 19, the opening of the height guide grooves 19 faces the height guide wheels 18, a frame crossbeam 26 is provided between the two frame side panels 1, a plurality of winding springs 27 are provided on the frame crossbeam 26, and the winding springs 27 are connected to the clamp box 4.

[0031] As the number of cloth layers increases, the shearing device 5 on the cloth laying machine 2 will automatically rise. When the shearing device 5 approaches the clamp box 4, the height guide wheel 18 thereon will enter the height guide groove 19 of the height guide block 17, and push the entire cloth pressing device to slide upward during the entry process, so that the cloth pressing device and the shearing device 5 are at the same height. When the cloth pressing device is lifted, the pulling force of the clamp box 4 by a plurality of winding springs 27 can ensure that the clamp box 4 maintains the lifted height after being lifted by the height guide block 17 without moving up or down at will.

[0032] like Figure 4 As shown, in this example, preferably, a plurality of lifting guide wheels 20 are provided on the side of the fixture side panel 3 facing the frame side panel 1, and a lifting guide groove 21 is provided on the frame side panel 1.

[0034] Preferably, in this embodiment, the two clamp side plates 3 are rotatably connected with a balance bar, and gears 23 are provided at both ends of the balance bar. The gears 23 mesh with the racks 22 on the frame side plates 1 to synchronize the rotation of the two gears 23 .

[0035] like Figures 5 to 7As shown, in this example, preferably, a limit groove 24 is provided on the outer side of the driving plate 13, and a limit sensor 25 is provided on the motor bracket 11, and the limit sensor 25 includes a micro switch, and an elastic sheet is provided on the micro switch, and a limit roller rolling in the limit groove 24 is provided at the end of the elastic sheet, and the two sides of the limit groove 24 are smoothly transitioned to the outer side of the driving plate 13. When the limit roller is located in the limit groove 24, the upper clamping body 9 and the lower clamping body 10 clamp the cloth head, and the elastic sheet does not trigger the micro switch, and when the limit roller contacts the outer side surface of the driving plate 13, the upper clamping body 9 and the lower clamping body 10 are in a separated state (including an initial clamping state and an upward linkage state).

[0036] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
