Detailed Description

The invention is further described with reference to the drawings and the detailed description.

As shown in fig. 1 to 4, the present invention includes a conveyor belt 3 and a top plate 4. Other technical features not mentioned herein are the same as the prior art.

The utility model discloses in use conveyer belt 3 to replace the transport running roller of leading edge paper feeding portion among the prior art. Conveyer belt 3 be the hold-in range to avoid skidding with band pulley 1, so that accurate control. The front end and the rear end of the conveying belt 3 are respectively arranged on a belt wheel 1, wherein one belt wheel 1 is a driving wheel, and the other belt wheel 1 is a driven wheel. The conveyer belt 3 is driven to move by the driving wheel. The conveyer belt 3 is provided with a tension pulley, the tension pulley can be a driven wheel, or other pulleys 1 can be additionally arranged, and the conveyer belt 3 can have a certain range of moving space through the arrangement of the tension pulley. As shown in fig. 4, the two ends of the wheel shaft where the tension wheel is located are installed on the bearing blocks 7, the bearing blocks 7 are fixed on the sliding blocks 8, the sliding blocks 8 are installed on the corresponding sliding rails 6, and the conveying belt 3 can be tensioned or loosened when the sliding blocks 8 slide on the sliding rails 6. The bearing seat 7 or the sliding block 8 is provided with a spring 9, and the spring 9 provides tension force for the bearing seat 7 and the sliding block 8 so as to tension the conveying belt 3.

The conveyer belt 3 on be equipped with a set of sucking disc 2, the top edge of sucking disc 2 be higher than the upper surface of conveyer belt 3, the bottom of sucking disc 2 is less than the lower surface of conveyer belt 3. As shown in fig. 3, the teeth on the inner side of the conveyer belt 3 are located at the edges of two sides of the conveyer belt 3, the bottom of the sucker 2 is located between two rows of teeth, and when the sucker 2 rotates to the belt wheel 1, the bottom of the sucker 2 can be squeezed through the action of the belt wheel 1. The top plate 4 is positioned between the two belt wheels 1, the top plate 4 is connected with a power device, and the top plate 4 can be driven to move up and down under the action of the power device. In this embodiment, the power device is a front rocker 5 and a rear rocker 5, each of the two rockers 5 has one end hinged to the top plate 4, and the other end of each of the two rockers 5 is hinged to the body. When the rocker 5 rotates, the top plate 4 is driven to jack upwards, the top plate 4 jacks the upper part of the conveyer belt 3 upwards and clings to the paper board 10, and the suction cups 2 on the conveyer belt 3 are tightly piled on the paper board 10; then rocker 5 drive roof 4 downstream, through the effect pulling conveyer belt 3 of take-up pulley reset, through the effect of sucking disc 2 with cardboard 10 area of below, then start conveyer belt 3, drive cardboard 10 through the effect of conveyer belt 3 and get into the cross cutting machine. When the sucking disc 2 moves to the position of the belt wheel 1, the belt wheel 1 extrudes the bottom of the sucking disc 2, and the air pressure in the sucking disc 2 after extrusion is changed into normal pressure from negative pressure, so that the sucking disc 2 can be easily separated from the paperboard 10, and the paperboard 10 can move forwards continuously.
