Abstract
Description
Technical Field
[0001] The utility model relates to a slitting machine, in particular to a paper conveying pressing wheel mechanism. Background Art
[0002] After being processed by slitting machines and other processing equipment, the paper needs to be driven by a paper feeding mechanism to be transported to the paper receiving station for stacking and collection. During the paper transportation process, in order to ensure that the paper can be transported flat, a pressure wheel mechanism is usually set to press the top of the transported paper. The traditional pressure wheel mechanism mainly includes a pressure wheel frame, on which pressure wheels are arranged, but the left and right positions of the pressure wheels are fixed. The position and angle of all the pressure wheels can only be adjusted by adjusting the position or angle of the pressure wheel frame. In actual use, the thickness of the paper at different positions may be different, or the height of the conveyor belt at different positions under the paper may be different. This makes it impossible to ensure that all positions of the paper are pressed and transported, and the flexibility of adjustment is poor. Utility Model Content
[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a paper conveying pressing wheel mechanism for solving the above-mentioned problem.
[0004] To this end, the utility model is implemented by adopting the following scheme:
[0005] A paper conveying pressure wheel mechanism comprises a mounting shaft fixed on a frame, characterized in that slidable pressure wheel seats are arranged on the mounting shaft, a locking assembly is provided corresponding to each pressure wheel seat, a belt winding wheel is provided on the pressure wheel seat, each pressure wheel seat is hinged to one end of a corresponding swing arm, a pressure wheel is provided on the swing arm, an independent swing adjustment assembly is provided corresponding to each swing arm, and also comprises a transmission roller and a paper pressing belt, wherein the paper pressing belt passes around the transmission roller, the belt winding wheel and the pressure wheel.
[0006] The belt pulley is rotatably arranged on a support shaft, the support shaft passes through a guide groove on a pressure wheel seat, a first adjusting screw is rotatably arranged on the pressure wheel seat, and the first adjusting screw is threadedly connected to the support shaft.
[0007] The pressure wheel seat is provided with a through hole for the fixed shaft to pass through, and a locking arm is extended from the pressure wheel seat. The locking arm and the pressure wheel seat together surround the through hole. There is a gap between one side of the locking arm and the pressure wheel seat. A locking bolt is rotatably provided on the locking arm, and a threaded hole threadedly connected to the locking bolt is provided on the pressure wheel seat.
[0008] The swing adjustment assembly includes an adjusting screw sleeve, the outer ring of the adjusting screw sleeve is threaded on the pressure adjusting screw seat, the pressure adjusting screw seat is fixed on the pressure wheel seat, the swing arm is provided with an extrusion part, a spring is tightly arranged between the extrusion part and the adjusting screw sleeve, a screw section extending from the extrusion part and passing through the adjusting screw sleeve is provided, and a locking nut is threaded on the top of the screw section.
[0009] The paper conveying pressure wheel mechanism of the above technical scheme has a simple structure and a reasonable design. By setting a slidable pressure wheel seat, the left and right position of each pressure wheel can be adjusted individually; by setting a swing arm on each pressure wheel seat and setting the pressure wheel on the swing arm, the pressure wheel height and the elastic extrusion force at the local position can be adjusted individually by independently adjusting the swing of the swing arm, which can adapt to the thickness differences of different positions of the paper and the height differences of different parts of the bottom support conveyor belt during actual use, and effectively improve its flexibility of use.

In this embodiment, the swing adjustment assembly includes an adjusting screw sleeve 8, the outer ring of the adjusting screw sleeve 8 is screwed on the pressure adjusting screw seat 9, the pressure adjusting screw seat 9 is fixed on the pressure wheel seat 6, an extrusion portion 12 is provided on the swing arm 11, a spring 10 is tightly provided between the extrusion portion 12 and the adjusting screw sleeve 8, a screw segment 13 extending from the extrusion portion 12 and passing through the adjusting screw sleeve 8, a locking nut 14 is screwed on the top of the screw segment 13, and also includes a transmission roller 1 and a paper pressing belt 3, the paper pressing belt 3 bypasses the transmission roller 1, the belt winding wheel 5 and the pressure wheel 4. Furthermore, the belt winding wheel 5 is rotatably arranged on the support shaft 20, and the support shaft 20 passes through the guide groove 18 on the pressure roller seat 6. The pressure roller seat 6 is rotatably provided with a first adjusting screw 19, and the first adjusting screw 19 is threadedly connected to the support shaft 20. By controlling the rotation of the first adjusting screw 19, the support shaft 20 can be driven to rise and fall under the guidance of the guide groove 18, so as to adjust the height of the belt winding wheel 5, and then adjust the tension of the paper pressing belt 3. The pressure roller seat 6 is provided with a through hole for the fixed shaft 7 to pass through, and the pressure roller seat 6 is extended with a locking arm 15, and the locking arm 15 and the pressure roller seat 6 jointly surround the through hole, and a gap 17 is provided between one side of the locking arm 15 and the pressure roller seat 6, and a locking bolt 16 is rotatably arranged on the locking arm 15, and the pressure roller seat 6 is provided with a threaded hole threadedly connected to the locking bolt 16.
