Description

Blade angle adjusting device of computer paper cutter Technical Field The utility model relates to the technical field of paper cutters, in particular to a blade angle adjusting device of a computer paper cutter. Background With the development of printing technology, printing equipment comprises a paper cutter, wherein the paper cutter is used for processing paper cutting requirements in the later stage of printing, and the development of the paper cutter is from a mechanical paper cutter to a tape control paper cutter and further to a microcomputer program control, color display and full image operation guide visualization processing, and a computer-aided cutting system for cutting external programming and editing production data. Based on the above, the present inventors have found that most computer paper cutters currently on the market employ a means of bolting the blade, by which the blade is tightly secured to the tool holder by a plurality of sets of bolts. Although the fixing structure can ensure the stability of the blade in the conventional cutting, the relative position between the blade and the tool rest is completely locked, so that the flexible adjustment of the angle cannot be realized. Different types of paper, such as coated paper, corrugated paper, rice paper and the like, have obvious differences in material hardness and toughness, and different angle requirements on the cutting blade, and the conventional bolt-fixed blade cannot meet the diversified requirements, so that the application range of the paper cutter is greatly limited. Accordingly, the present invention provides a device for adjusting the blade angle of a computer paper cutter, which aims to achieve the purpose of higher practical value. Disclosure of utility model The utility model aims to provide a blade angle adjusting device of a computer paper cutter, which solves the problems that the prior bolt-fixed blade in the background art cannot meet the diversified requirements and greatly limits the application range of the paper cutter. In view of the above problems, the technical scheme provided by the utility model is as follows: The utility model provides a computer paper cutter blade angle adjusting device, includes placing mechanism, adjustment mechanism, placing mechanism includes the box, the cutting bottom plate is installed to the upper end of box, adjustment mechanism includes a pair of sliding sleeve, a pair of the sliding sleeve sets up respectively in the both ends of box, the inside of sliding sleeve is all slidable mounting has the movable block, a pair of fixed mounting has the movable box between the movable block, the bottom slidable mounting of movable box has the movable seat, the inside rotation of movable seat is connected with the blade, one side fixed mounting of movable seat has the transmission case, the inside of sliding sleeve all is equipped with first electric telescopic handle, a pair of the top of first electric telescopic handle is connected with the bottom of a pair of movable block respectively, a pair of the bottom of first electric telescopic handle is connected with the both sides of box respectively. Further, the inside rotation of transmission case is connected with the worm wheel, one side center pin of worm wheel is connected with one side center pin of blade. The blade angle adjusting device has the beneficial effects that the worm wheel is connected with the blade center shaft, a transmission basis is provided for angle adjustment of the blade, and the blade can be driven to synchronously rotate through rotation of the worm wheel, so that adjustment of the blade angle is realized, and different cutting angle requirements are met. Further, a worm is rotatably connected to one side of the worm wheel inside the transmission case, and the worm wheel are meshed with each other. The further scheme has the advantages that the worm is meshed with the worm wheel, rotation of the worm is converted into rotation of the worm wheel by utilizing the characteristic of worm wheel and worm transmission, and then the blade is driven to rotate, meanwhile, the worm wheel and worm transmission has a self-locking function, stable fixing of the angle of the blade can be achieved, and accurate cutting angle is ensured. Further, a first servo motor is fixedly arranged at the upper end of the transmission case, and the output end of the first servo motor is connected with the worm in a transmission manner. The beneficial effect of adopting above-mentioned further scheme is, first servo motor provides power for the worm, through transmission drive worm rotation to drive worm wheel and blade rotation, realize the electric control to blade angle, convenient operation is swift, can be according to tailorring the quick adjustment blade angle of demand, improves work efficiency. Further, the inside rotation of removal case is connected with the screw rod, threaded connection has the slider on the screw rod, the b
