Detailed Description
The direction of the arrow in fig. 1 is the feeding direction of the sheet.
As shown in fig. 1, the constant friction mechanism for a paper winding drum of the present invention comprises a paper winding drum 1, a paper winding drum 2 is wound on the outer surface of the paper winding drum 1, a guide roller 3 is arranged above the paper winding drum 1, and paper drawn from the paper winding drum 2 bypasses the guide roller 3 and then is sent to a next process, such as a mechanism for combining different papers together;
a brake belt 4 is pressed below the paper roll 2, the right side edge of the brake belt 4 extends out of the right end of the paper roll 2 and is connected with a right pull rope 5, and the right pull rope 5 is connected with a fixed object on the right side of the paper roll 1; the left side edge of the brake belt 4 extends out of the left end of the paper roll 2 and is upwards connected with a left pull rope 6;
a pulley 7 is arranged on a fixed object (such as a building structure or a special vertical frame) above the left side of the paper winding cylinder 1; the left pull rope 6 passes through the top of the pulley 7 from the right side of the pulley 7, and then extends downwards from the left side of the pulley 7 and is connected with a balancing weight 8.
The braking band 4 may be made of rubber or canvas or plastic or metal plate.
A tension adjusting roller 9 is arranged between the paper winding tube 1 and the guide roller 3, and the tension adjusting roller 9 is pressed with the paper led out from the paper winding 2.
The fixture in the right of the paper roll 1 is a pull ring device, the pull ring device comprises a connecting seat 10 and a pull ring 11 connected with the connecting seat 10, the right pull rope 5 is connected with the pull ring 11, and the connecting seat 10 is fixed on the building structure in the right of the paper roll 1.
The balancing weight 8 is connected with a constant force spring 12 downwards, the lower end of the constant force spring 12 is connected with the ground, and the constant force spring 12 is in a stretching state.
