The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

As can be seen from fig. 1 to 3, the present invention includes a bottom plate 1, a support is arranged at the upper end of the bottom plate 1, an electric cylinder 2 is hinged on the support, the electric cylinder 2 can swing left and right along a hinge shaft, an arc plate 3 is fixed at the upper end of the extending end of the electric cylinder 2, a plurality of arc grooves 4 are arranged on the outer arc surface of the arc plate 3, a plurality of saws 5 with horizontal front and back axes are arranged above the arc plate 3, the rotation direction of the plurality of saws 5 is opposite to the rotation direction of the electric cylinder 2, saw blades of the plurality of saws 5 correspond to the arc grooves 4 one by one, a compression roller 6 with horizontal front and back axes is respectively arranged at the left and right sides of the plurality of saws 5, and a spring 7 capable of making the compression roller 6 reset downwards is arranged on a core shaft of the compression roller 6.

In order to realize the rotation driving of the electric cylinder 2, a first stepping motor 8 is fixed on the bracket, the first stepping motor 8 is fixedly connected with a hinge shaft of the electric cylinder 2, and the rotation directions of the first stepping motor 8 and the second stepping motor 11 are opposite.

In order to realize the installation of

arc

3, 3 lower extremes of arc are fixed with an arc 9 coaxially, and arc 3 is installed on arc 9, and the end that stretches out of electricity jar 2 upper end is fixed on arc 9, and arc 4 is for leading to the groove, can effectually prevent that the rubber piece from blockking up arc 4.

In order to realize the installation of the compression roller 6 and the multi-blade saw 5, the rear side of the bottom plate 1 is provided with an L-shaped frame 10, the rear end of a mandrel of the multi-blade saw 5 penetrates through a vertical plate end of the L-shaped frame 10 and is rotatably installed on the L-shaped frame 10, the L-shaped frame 10 is fixedly provided with a second stepping motor 11 capable of driving the multi-blade saw 5 to rotate, the front end of the multi-blade saw 5 is installed on a transverse plate end of the L-shaped frame 10 through a bearing seat, the left side and the right side of the multi-blade saw 5 are respectively provided with a set of telescopic rods 12, each set of telescopic rods 12 comprises a front telescopic rod and a rear telescopic rod, one end of each telescopic rod 12 is fixed on the transverse plate of the L-shaped frame 10, the other end of each telescopic rod is hinged with the end of the corresponding mandrel of the compression roller 6, and the spring 7 is sleeved on the corresponding telescopic rod 12.

The specific working process of the utility model is as follows: when the device is used, the first stepping motor 8 drives the electric cylinder 2 to keep the axis of the electric cylinder vertical, the extending end of the electric cylinder 2 is controlled to retract, the arc-shaped plate 3 and the multi-blade saw 5 are uniformly contacted with the compression roller 6 to provide space for workers to install rubber sheets, after the workers place the rubber sheets on the arc-shaped plate 3, drive electric cylinder 2 extension and make 3 jack-up rubber sheets of arc make two compression rollers 6 compress tightly the rubber sheet both sides and the intermediate position of the 5 contact rubber sheets of multi-disc saw that make, open first step motor 8 and second step motor 11 this moment, first step motor 8 rotates and makes 2 horizontal hunting of electric cylinder, second step motor 11 rotates and makes 5 rotations of multi-disc saw, multi-disc saw 5 rotates and makes the rubber sheet cut into strips, the horizontal hunting of electric cylinder 2 makes 5 cuts the rubber sheet to both sides from the centre of multi-disc saw 5, compression roller 6 compresses tightly can not make the rubber sheet break away from arc 3 after 5 motion of multi-disc saw to the rubber sheet tip in the both sides of multi-disc saw 5.
