The utility model discloses a regulation atmospheric pressure size, the adjustment pinch roller that can be very convenient and the packing force of carry over pinch rolls, have rational in infrastructure, installation convenient operation, advantage that the cost of manufacture is low.
Description
Technical field
This utility model relates to a kind of printer traction apparatus pressure roller structure.
Background technology
At present, traction apparatus bag motor, frame, main carry-over pinch rolls and pressure roller on the printer, transmission for stock, it is high that this structure adds technological requirement to pressure roller, installing and adjust complexity, when adjusting thrust, pressure roller is translation mode, needs to be adjusted respectively at the two ends of pressure roller, adjust inconvenience, bias-pressure phenomenon easily occurs.
Summary of the invention
The deficiency existed in view of prior art, this utility model provides a kind of printer traction apparatus pressure roller structure, breach original frame mode, have employed two eccentric bushings of installation on a wheel pressing shaft, pinch roller is installed on eccentric bushing again, by swing arm by the rotary motion that transform linear motion is wheel pressing shaft of mini cylinder, under eccentric bushing effect, pinch roller is pressed to traction wheel or leaves traction wheel, by regulation air pressure size, the thrust of pinch roller and carry-over pinch rolls can be adjusted very easily, have rational in infrastructure, install easy to operate, the advantage that cost of manufacture is low.
nullThis utility model relates to a kind of printer traction apparatus pressure roller structure，Including carry-over pinch rolls 7，Left memorial archway seat 1，Right memorial archway seat 2，First pinch roller 8，Second pinch roller 12，Described first pinch roller 8 is arranged on the first eccentric bushing 10 by the first deep groove ball bearing 9，Described second pinch roller 12 is arranged on the second eccentric bushing 14 by the second deep groove ball bearing 13，Described first eccentric bushing 10 is fixedly mounted on wheel pressing shaft 11，Described second eccentric bushing 14 is fixedly mounted on wheel pressing shaft 11，It is positioned at the left side of the first eccentric bushing 10，The left end of described wheel pressing shaft 11 is installed in the second rhombus bearing 15，Described wheel pressing shaft 11 right-hand member is installed in the first rhombus bearing 3，Described first rhombus bearing 3 is arranged on right memorial archway seat 2 medial surface，Described second rhombus bearing 15 is arranged on left memorial archway seat 1 medial surface，Swing arm 5 also it is installed with on described wheel pressing shaft 11,One end of described swing arm 5 is hinged mutually by the tailpiece of the piston rod of bolt 4 with mini cylinder 6，The tail end of described mini cylinder 6 is hinged at cylinder and installs on axle 601，Described cylinder is installed axle 601 and is fixedly mounted on the inner side of right memorial archway seat 2.
Accompanying drawing explanation
Fig. 1 is right axonometric drawing of the present utility model.
Fig. 2 is left axonometric drawing of the present utility model.
Detailed description of the invention
As depicted in figs. 1 and 2, the first pinch roller 8 is arranged on the first eccentric bushing 10 by the first deep groove ball bearing 9, and the first pinch roller 8 can rotate flexibly；Second pinch roller 12 is arranged on the second eccentric bushing 14 by the second deep groove ball bearing 13, and the second pinch roller 12 can rotate flexibly；First eccentric bushing 10 is fixedly mounted on wheel pressing shaft 11, second eccentric bushing 14 is fixedly mounted on wheel pressing shaft 11, it is positioned at the left side of the first eccentric bushing 10, the left end of wheel pressing shaft 11 is installed in the second rhombus bearing 15, wheel pressing shaft 11 right-hand member is installed in the first rhombus bearing 3, first rhombus bearing 3 is arranged on right memorial archway seat 2 medial surface, second rhombus bearing 1 is arranged on left memorial archway seat 1 medial surface, swing arm 5 also it is installed with on wheel pressing shaft 11, one end of swing arm 5 is hinged mutually by the tailpiece of the piston rod of bolt 4 with mini cylinder 6, the tail end of mini cylinder 6 is hinged at cylinder and installs on axle 601, cylinder is installed axle 601 and is fixedly mounted on the inner side of right memorial archway seat 2.
The operation principle of the technical program is: mini cylinder 6 is under compressed-air actuated effect, piston rod stretches out or retracts, wheel pressing shaft 11 is driven to rotate by swing arm 5, drive the first eccentric bushing 10 and the second eccentric bushing 14 synchronous axial system being arranged on wheel pressing shaft 11 simultaneously, owing to the first pinch roller 8 is arranged on the first eccentric bushing 10 by the first deep groove ball bearing 9, second pinch roller 12 is arranged on the second eccentric bushing 14 by the second deep groove ball bearing 13, under wobbler action, first pinch roller 8 Tong Bu presses to or leave carry-over pinch rolls 7 with the second pinch roller 12, thus realize the compression to carry-over pinch rolls 7 or loosen, and the size of thrust can be adjusted very easily by the size adjusting air pressure.
