Abstract

The utility model belongs to an involute cutter paper cutter which is formed by that a motor is arranged on a fixed bolster, the motor is connected with an endless screw through a belt roller, and the endless screw engages with a worm wheel which is connected with an involute cutter through a worm wheel shaft. The utility model can be used in the technical field of printing and paper cutting, having the advantages of simple structure, convenient use, and low price.

Description

Paper cutter

The utility model belongs to a kind of paper cutter.

Present paper cutter all is to adopt straight parallel angle of throat tool cut paper, and its problem is that volume is big, complex structure, and power consumption is big.The utility model has designed a kind of paper cutter for overcoming this problem, and it has simple in structure, and is easy to use, the characteristics that cost is low.

The purpose of this utility model provides a kind of paper cutter of involute cutting knife.

The utility model is achieved in that involute cutting knife paper cutter is to adopt motor is housed on fixed support, motor connects worm screw by belt pulley, the worm engaging worm gear, and worm gear connects the involute cutter by worm-wheel shaft.

On the two ends of support, fixed head is housed, two slide bars and a worm screw are installed on fixed head side by side, the held stationary frame is housed on slide bar and worm screw, the worm gear of a worm engaging is housed in the held stationary frame, worm gear is installed on the held stationary frame by worm-wheel shaft, and connects the involute cutter.

On two fixed heads, travel switch is housed, on support, has shift knob.

During work, cutter and worm gear are fixed in the same rotating shaft, along with the rotation of worm screw, move while cutter and worm gear rotate the horizontal direction of prolonging worm screw, and the paper below the cutter just cuts gradually.Run into travel switch when tool motion during to the top, make the motor stall, the cutter stall, cut paper finishes.When paper when platform takes out, make the motor wraparound by reversing switch, cutter is drawn back, and has fallen back on terminal and has run into travel switch, motor stall, cutter stall.Get final product cut paper by the feed switch again when needing cut paper.

The utlity model has simple in structure, easy to use, low-cost characteristics, and can be used for printing the cut paper technical field.

Concrete structure of the present utility model and embodiment are provided by the following drawings;

Fig. 1 is a general structure schematic diagram of the present utility model;

Fig. 2 is a cutter structure schematic diagram of the present utility model.

Below in conjunction with accompanying drawing to concrete structure of the present utility model and execute example and do with further instruction.
