Description

Clutch brake

Technical field

The utility model relates to a kind of brake gear, and especially a kind of clutch brake being applied on high-speed web printing machine, belongs to printing equipment field.

Background technology

China is the history culture ancient country that has four inventions, as far back as Northern Song Dynasty Bi Noboru, just invented typography, this has opened the arrival of printing New Times, and along with scientific and technological progress, printing technology is also constantly by perfect, various high-tech printing equipments are out manufactured, digital printing, the high level printing technology such as four-color process is constantly used, for printing, the printing equipment that good printing technology must have is supported, among this, the solid printing machine of screen process press and UV light has become main flow gradually, it is high that they have printing efficiency, effective, the plurality of advantages such as repair rate is low.

The printing enterprise of China mainly concentrates Wenzhou Long Gang at present, the printing city that Long Gang Ye Shi China is famous, and due to the restriction of various factors, although large-scale printing equipment is constantly introduced into, but their relevant equipment part is not also caught up with the step of international advanced printing technology, now when printing, for needs anxious stop or and fault while needing repairing, want to allow printing equipment stop to take general be all manual parking or the mode of instant cut-off, although can reach like this effect of parking, but adopt manual parking stricter for the requirement of manpower, adopt the mode of instant cut-off stop and can serve unnecessary wearing and tearing to machinery equipment band, this just needs a kind of parts with reliable brake function that match with it to support the operation of high speed printing equipment.

Utility model content

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of clutch brake that can reach stably stop effect is provided, and has solved the high-speed press parking inconvenience of prior art, the easy problem that machinery equipment is caused to heavy wear.

For achieving the above object, the technical solution of the utility model is:

Clutch brake, comprise printing machine main body, the driving shaft being connected by the first shaft coupling with printing machine main body, on described driving shaft, be connected with driven shaft, on driven shaft, be provided with the belt pulley that can connect belt, between driven shaft and driving shaft, by the second shaft coupling, be connected, annular mounting base is installed between the second shaft coupling and driven pulley, on mounting base, dispose ring-shaped brake wheel, on mounting base, be also connected with pneumatic actuator, described pneumatic actuator is controlled interlock and the release of brake wheel.

In the technical program, after printing machine main body is connected with brake gear, as long as set in advance the brake pressure needing and discharge air pressure in pneumatic actuator, by remote microcomputer, ring-shaped brake wheel is being controlled, not only control is very accurate, and parking effect is better.

As preferably, between ring-shaped brake wheel and driven pulley, by gear, mesh.

If annular is established the mode that adopts gear engagement between wheel and driven pulley, the one, be convenient to the I&M on equipment, but because the size of gear can regulate, user can select the gear of suitable size to brake according to the needs of high speed printing equipment.

The beneficial effects of the utility model are: stop or the mode of instant cut-off is stopped and compared with employing is in the past manual, the interlock that the pneumatic actuator that the utility model adopts remote microcomputer to control is controlled annular brake wheel realizes parking with release, there is parking reliable for effect, without potential safety hazard, and the advantage less to the wearing and tearing of machine.

Accompanying drawing explanation

Fig. 1 is complete section schematic diagram of the present utility model.

In figure: printing machine main body 1, driving shaft 2, the first shaft coupling 31, the second shaft couplings 32, driven shaft 4, pneumatic actuator 5, brake wheel 6, mounting base 7.

The specific embodiment

Below in conjunction with accompanying drawing, and, the utility model is described further in conjunction with the embodiments.

Embodiment:

As shown in Figure 1, clutch brake, comprise printing machine main body 1, the driving shaft 2 being connected by the first shaft coupling 31 with printing machine main body 1, on described driving shaft 2, be connected with driven shaft 4, on driven shaft 4, be provided with the belt pulley that can connect belt, between driven shaft 4 and driving shaft 2, by the second shaft coupling 32, be connected, annular mounting base 7 is installed between the second shaft coupling 32 and driven pulley 4, on mounting base 7, dispose ring-shaped brake wheel 6, on mounting base 7, be also connected with pneumatic actuator 5, described pneumatic actuator 5 is controlled interlock and the release of brake wheel 6.

Preferably, ring-shaped brake is taken turns on 6 and by gear, is meshed between driven pulley 4.

During the utility model work, in advance remote microcomputer and pneumatic actuator 5 are connected, input brake pressure and release air pressure, when needs stop, microcomputer sends instruction, pneumatic actuator 5 completes inflation, air pressure constantly raises, and reaches after brake pressure, and the brake cylinder in pneumatic actuator 5 ejects, with 6 effects of ring-shaped brake wheel, by ring-shaped brake take turns 6 and driven shaft 4 between friction realize the parking of high-speed press.

Compared with prior art, the utlity model has brake reliably, to advantages such as wear and tear in machines are little.
