Described Returnning spring is installed in the spring eye in the brake disc.
Described Moving plate is a whole iron block, has the V-shape belt groove on the excircle of Moving plate.
Compared with prior art, the beneficial effects of the utility model are: the special-purpose electromagnetic clutch device of the utility model paper cutter does not have this structure of slip ring, electromagnetic coil is positioned at Moving plate inside, fix by a strut, electromagnetic coil remains motionless in the complete machine rotation operation process, energy loss is very little, Moving plate is that whole iron block is formed, behind coil electricity, Moving plate integral body generates an electromagnetic field, and the elastic force that magnetic force overcomes Returnning spring breaks away from brake disc and land, and then fits tightly on the friction material of Moving plate, realization cuts action, electromagnetic coil outage back brake disc is fitted with land under the spring force effect, realize fast braking, and clutch brake power is big, the adjusting gap is convenient, has reduced potential safety hazard.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.Be necessary to be pointed out that at this present embodiment can not be interpreted as the restriction to the utility model protection domain, the person skilled in the art in this field can make some nonessential improvement and adjustment according to above-mentioned content of the present utility model.
As shown in Figure 1, the special-purpose electromagnetic clutch device of a kind of paper cutter, this electromagnetic clutch device comprises input shaft 12, overcoat at the clutch shaft bearing 9 of input shaft 12 1 ends tightens intrinsic Moving plate 6, there is a solenoid bore one end inside of Moving plate 6, the inside is equipped with electromagnetic coil 7, there is one second bearing 8 electromagnetic coil 7 belows, this second bearing 8 is supporting electromagnetic coil 7, the strut 10 that is fixed on simultaneously on the casing 1 has also played the effect that limits the position of electromagnetic coil 7, external power cord directly is connected with electromagnetic coil 7, and this device has not just had the slip ring structure.Because it is motionless that said structure arrangement, electromagnetic coil 7 electromagnetic coil in complete machine rotation operation process remains, energy loss is very little.Because power line is direct and electromagnetic coil 7, has just reduced the slip ring structure, structure is simplified more, and Security strengthens.
With the Moving plate 6 certain interval place that is separated by be brake disc 4, one end of brake disc 4 is fixedlyed connected by the standard spline with input shaft 12, the other end of brake disc 4 and land 3 fit tightly, in the spring eye of brake disc 4 near the inside of input shaft 12 1 ends Returnning spring 11 is installed, this Returnning spring 11 exposes end face and pastes mutually with back-up ring 13.Described land 3 is to be installed on the casing 1 by adjustment screw 2, drives brake disc 4 thereby connect land 3 by adjustment screw 2, finally reaches the purpose in the gap of regulating Moving plate 6 and brake disc 4.Certainly have groove at Moving plate 6 near on the end face of brake disc 4, and friction material 5 is inserted this groove.Moving plate 6 is a whole iron block, has the V-shape belt groove on the excircle of Moving plate 6.The Moving plate 6 that whole iron block is formed is changed the original engaging and disengaging gear and the split-type structural of belt pulley, simple in structure and efficient height.Be provided with adjustment screw 2 simultaneously, thereby made things convenient for the gap of regulating Moving plate 6 and brake disc 4.Friction material 5 is critical components, directly has influence on the performance of product.
The utility model is changed the characteristics of traditional electromagnetic clutch device, removed the slip ring structure, when paper cutter master electric motor starting, electromagnetic coil 7 keeps motionless, belt drives Moving plate 6 rotations on the Moving plate 6, brake disc 4 fits tightly with land 3 under the effect of Returnning spring 11, and whole cutting mechanism is in braking state, when electromagnetic coil 7 energisings, Moving plate 6 produces suction, and the elastic force that overcomes Returnning spring 11 moves right brake disc 4, and this moment, brake disc 4 was thrown off with land 3, fit with the friction material 5 on the Moving plate 6, drive input shaft 12 and rotate, paper cutter realizes cutting action, when electromagnetic coil 7 outages, Moving plate 6 is thrown off rapidly with brake disc 4, brake disc 4 fits tightly once more with land under the effect of Returnning spring 11, finishes the clutch process one time, and paper cutter is finished and once cut action.
Introduce the method for regulating the clutch gap below again:
When the clutch excesssive gap, in the time of can not reaching the requiring of quick adjustment, can adjust adjustment screw 2, screw in adjustment screw 2 and promptly reduce the gap, withdraw from adjustment screw 2, promptly increase the gap.
