A kind of hob type paper cutting apparatus
The present invention relates to a kind of paper cutting apparatus, particularly a kind of hob type paper cutting apparatus.
On market, existing most of impact printer does not all have the function of automatic paper-cutting, and paper or bill by having printed data that user can only be artificial are torn, and affect like this operating efficiency.Follow China's rapid development of economy, user has had higher requirement for operating efficiency, also the automation of equipment is required also more and more highlyer, and impact printer will become one of the development trend in impact printer future with automatic paper-cutting function.
Summary of the invention
The object of this invention is to provide a kind of hob type paper cutting apparatus, paper or the bill of having printed data can be cut, thereby make printer there is the function of automatic cutting.
Technical scheme of the present invention is, a hob type paper cutting apparatus, comprises support, the axis of guide, transmission mechanism, goes out cardboard, drive motors, electric machine support, guide plate, position sensor, control system, paper injection plate, roller, guiding trestle, rolling moving knife, stationary knife, Compress Spring;
Described support is " U " shape framework, and axis of guide both sides are fixedly installed on the end, two side of " U " shape framework, and guide plate is fixedly installed on the bottom surface of " U " shape framework;
Described guiding trestle is sheathed on the axis of guide and inner side is provided with the roller that can roll along guide plate along with moving left and right of guiding trestle; Described belt is rack-mount by transmission mechanism and tensioning bracket component, belt top snaps in the belt teeth groove on guiding trestle, belt bottom and the engagement of rolling moving knife belt wheel, and rolling moving knife belt wheel is installed on rolling moving knife, the cutting edge of rolling moving knife contacts with the stationary knife that tilts to be installed on guiding trestle downside;
Described position sensor connection control system, control system connects and controls by the rack-mount drive motors of electric machine support, rotatablely moving of drive motors passes to belt by transmission mechanism, belt drives guiding trestle to move left and right along the axis of guide, drive the rolling moving knife belt wheel rotation be arranged on rolling moving knife, the moving knife that makes to roll is along stationary knife cutting edge rectilinear motion and self rotatablely move simultaneously;
Described rolling moving knife arranged outside has Compress Spring, and rolling moving knife is the extruding of spring by compression, and the moving knife that rolls while making to cut a sheet of paper is adjacent to and contacts with the cutting edge of stationary knife;
Described guiding trestle arranged outside has paper-pressing mechanism, and is provided with the paper injection plate parallel with the axis of guide between paper-pressing mechanism and stationary knife.
Further, described paper-pressing mechanism comprises platen support casing, platen spring, platen assembly and platen assembly support; Described platen assembly support is fixedly installed in guiding trestle outside, platen support casing is sheathed on platen assembly support, and connect platen assembly by platen spring, pressure roller in platen assembly rolls along with moving left and right of guiding trestle, and by platen spring, platen assembly is moved up and down along with paper sheet thickness changes.
Further, described rolling moving knife and stationary knife cutting edge contact side are fluted.
Further, on described rolling moving knife, have the hole slot connecting with the moving knife belt wheel that rolls.
During work, after the driving signal that drive motors receiving control system sends, start rotation, by transmission mechanism, drive rolling moving knife to move, make the occlusal position continuous moving of stationary knife and rolling moving knife realize automatic cutting, after rolling moving knife moves a certain distance, control system is sent signal and is made drive motors reversion, and guiding trestle starts to reset, complete the rear position sensor feedback signal that resets and to control system, drive motors is stopped operating, one time automatic cutting completes.
The invention has the beneficial effects as follows, the structure of rolling moving knife and stationary knife and cutting guarantee to cut a sheet of paper accurately and reliably.Be applicable to the paper cutting apparatus of printer, paper or the bill of having printed data can be cut, thereby make printer there is the function of automatic cutting.Modularized design is manufactured, and cost is lower, maintenance easy accessibility; In the process of cutting a sheet of paper, pressure angle remains unchanged, and makes cut paper steady; Cutting a sheet of paper, modular construction is simple, the good reliability of cutting a sheet of paper.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiments, the present invention is described in further detail.
According to Fig. 1-4 explanation embodiment of the present invention, present embodiment is paper cutting apparatus to be arranged on to the application example of printer end.
As Figure 1-4, paper cutting apparatus by drive motors 5, electric machine support 6, transmission mechanism 3, rolling moving knife 18, rolling moving knife belt wheel 17, stationary knife 19, spring 20, support 1, platen assembly 14, platen spring 13, platen assembly support 22, platen support casing 12, guiding trestle 16, roller 15, the axis of guide 2, guide plate 7, belt 21, tensioning bracket component 8, position sensor 9, control system 10, paper injection plate 11, go out cardboard 4 etc. and form.Platen assembly support 22, spring 20, roller 15 and the rolling moving knife belt wheel 17 being assembled into after one are arranged on guiding trestle 16 with rolling moving knife 18 assemblies, platen assembly 14 and platen spring 13 are assemblied on platen assembly support 22 by platen support casing 12, guiding trestle 16 is arranged on support 1 by the axis of guide 2, roller 15, platen assembly 14 respectively be arranged on guide plate 7 on support 1, go out cardboard 4 and contact.Belt 21 tops that are arranged on support 1 by transmission mechanism 3 and tensioning bracket component 8 are snapped in to the belt teeth groove on guiding trestle 16, belt 21 bottoms and 17 engagements of rolling moving knife belt wheel.
Cut a sheet of paper and along the paper injection plate 11 being arranged on support 1, send into after paper cutting apparatus certain distance, control system 10 is sent driving signal to the drive motors 5 being arranged on support 1 by electric machine support 6, rotatablely moving of drive motors 5 passes to belt 21 by transmission mechanism 3, thereby the moving knife 18 that makes to roll moves and also starts rotation simultaneously with guiding trestle 16, being arranged on spring 20 on guiding trestle 16 moving knife 18 that makes to roll is adjacent to and contacts all the time with the cutting edge that tilts to be arranged on stationary knife 19 on support 1, when moving to right-hand member from left end, rolling moving knife 18 completes after cut paper, drive motors 5 reversions make guiding trestle 16 start the oppositely mobile initial position that arrives, the rear reset of trigger position sensor 9 completes, the end of once cutting a sheet of paper.
When cut out paper sheet thickness changes, between platen assembly 14 and platen support casing 12, the decrement of platen spring 13 can change, make platen assembly 14 change and to move up and down along with paper sheet thickness, platen spring 13 can regulate the active force between roller 15 and guide plate 7 simultaneously.
Advantage of the present invention has: modularized design manufacture, and cost is lower, maintenance easy accessibility; In the process of cutting a sheet of paper, pressure angle remains unchanged, and makes cut paper steady; Cutting a sheet of paper, modular construction is simple, the good reliability of cutting a sheet of paper.
