Description
Technical field
Utility model relates to field of mechanical technique, refers to a kind of automatic control system, especially a kind of highly sensitive web tension automatic control system.
Background technology
Modern printing machine generally by locing up, inking, impression, the mechanism such as defeated paper (comprising folding) form.Its operation principle is: the writings and image that first will print makes forme, dress on the printer, then ink is coated on by artificial or printing machine place forme having writings and image, be transferred to directly or indirectly again on paper or other stocks (as textile, metallic plate, plastic cement, leather, plank, glass and pottery), thus copy the printed matter identical with forme.The invention of printing machine and development, the propagation for human civilization and culture has important function.Although printing machine has possessed more function now, substantially can both complete needed on market, but it still also exists some shortcomings part, especially at paper tape output facet, it is related to the process of whole printing, and whether can completely is carried out, the quality of relation print product.And the paper tape of printing machine exports and imperfection at present, once go wrong, whole printing is just caused to stop, as paper tape fracture, so that whole production cost improves.Similar problem often appears in the paper tape especially on high speed rotary cylinder printing machine, and e.g., loosening appears in the printing paper belt tension on reel, and cause printing unintelligible, yield rate is not high; In addition, high speed rotary cylinder printing machine, in the process of work, occurs that in order to prevent printing paper belt tension loosening or tension etc. are improper, people have and go to improve by once method, but more or less precision is not very high, reaction is slow, all cannot realize the optimum tension of paper tape for a long time.
Utility model content
The object of utility model is for the problems referred to above, provide one can automatic constant web tension constant, all the time allow paper tape be within the scope of optimum tension, the printing of guaranteeing reaches optimum efficiency, stops the web tension automatic control system that breaking or excessively relaxing appears in paper tape.
For achieving the above object, utility model have employed following technical proposal: highly sensitive web tension automatic control system, comprise several floating rods horizontally disposed, floating rod one end is connected with roll web, the central shaft of this roll web is the floating neutral axle that metal manufactures, the other end of floating rod is connected with paper feeding stick, it is characterized in that, be provided with the tension sense that can fluctuate between paper feeding stick and floating rod and answer rod, this tension sense is answered on rod by drive link being connected with integrated signal amplifier, integrated signal amplifier is connected with scale amplifying module and the power amplifier module of series connection, scale amplifying module and power amplifier module are parallel with regulating resistance, be provided with below described floating neutral axle and connect magnetic powder brake with integrated signal amplifier.
In the highly sensitive web tension automatic control system of above-mentioned one, described drive link is connected to the center that tension sense answers rod, is connected with hinged seat in the middle of drive link.
In the highly sensitive web tension automatic control system of above-mentioned one, described floating neutral axle is provided with T-shaped metal backup.
In the highly sensitive web tension automatic control system of above-mentioned one, described paper feeding stick rear end is provided with adjustment roller bearing.
In the highly sensitive web tension automatic control system of above-mentioned one, described integrated signal amplifier comprises input voltage and signal voltage, and the resistance of the parallel connection of two different value numbers, these two resistance and the Capacitance parallel connection with switch.
In the highly sensitive web tension automatic control system of above-mentioned one, described integrated signal amplifier is connected with manual adjustments circuit.
In the highly sensitive web tension automatic control system of above-mentioned one, described tension sense is answered below rod and floating rod and is equipped with relief spring.
Compared with prior art, the advantage of utility model is: collected the corresponding signal that drive link brings by integrated signal amplifier, thus change the voltage of magnetic powder brake, realize magnetic powder brake produce the size of magnetic force, thus can be good at controlling the position between T-shaped metal backup and magnetic powder brake, play the tension force tightening or loosen paper tape; The susceptibility of whole system to Tensity size can be improved by voltage signal, web tension is in best scope all the time.
Accompanying drawing explanation
In order to be illustrated more clearly in utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in utility model embodiment, be clearly and completely described the technical scheme in utility model embodiment, obviously, described embodiment is only utility model part embodiment, instead of whole embodiments.Based on the embodiment in utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of utility model protection.
As shown in Figure 1, a kind of highly sensitive web tension automatic control system, comprise horizontally disposed several floating rod 3 and paper tapes 2, in this enforcement, floating rod is provided with one.Actual conditions can be added as required.Floating rod one end is connected with roll web 1, and the central shaft of this roll web is the floating neutral axle that metal manufactures, and be provided with magnetic powder brake 7 below described floating neutral axle, described floating neutral axle is provided with T-shaped metal backup 8.Magnetic powder brake is arranged on below T-shaped metal backup, and when producing electromagnetic force, T-shaped metal backup not only can block roll web, under the pulling of electromagnetic force, and can by roll web together pulled down.
The other end of floating rod is connected with paper feeding stick, and paper feeding stick rear end is provided with adjustment roller bearing 5.Be provided with the tension sense that can fluctuate between paper feeding stick 6 and floating rod and answer rod 4, described tension sense is answered below rod and floating rod and is equipped with relief spring 9.Relief spring can be avoided, because electromagnetic force is excessive, causing situations such as being broken by paper tape.
