The specific embodiment
The following stated is preferred embodiment of the present invention only, is not that scope of the present invention is limited.
Embodiment 1, see accompanying drawing 1,2,3,4,5, a kind of perforating device for binder, comprise the main shaft 1 with connection chamber 101, the motor 8 of drive shaft rotation, cutter 2 with endoporus 204 reaches the axle bed 9 that is used for installing main shaft, in axle bed 9, be provided with bearing 12, the inner ring of bearing is connected with main shaft, the outer ring is fixedly connected with axle bed, bearing 12 is two, be arranged on the up and down two ends of axle bed, the output shaft of described motor 9 is provided with driving wheel 13, and described main shaft is provided with driven pulley 14, described driving wheel 13 be connected driven pulley 14 and connect by transport tape 15, driving wheel and driven pulley can adopt pitch wheel certainly.Described cutter 2 upper ends are provided with the contiguous block 201 that is fixedly connected with described connection chamber 101, described endoporus 204 and described connection chamber 101 are communicated with, endoporus runs through the upper and lower end face of described cutter, described main shaft 1 is provided with crumb loading cover 10, the crumb loading cover can adopt the modes such as screw connection or welding to be fixed on the main shaft, be provided with crumb loading chamber 1001 in the described crumb loading cover 10, described connection chamber 101 is communicated with described crumb loading chamber 1001 by the connecting hole 104 that is arranged on the main shaft 1, described crumb loading chamber 1001 is provided with chip discharging tube 11, chip discharging tube 11 is communicated with described crumb loading chamber 1001, paper scrap in the crumb loading chamber 1001 can be discharged, simultaneously, described main shaft 1 is provided with so that the anticreep bindiny mechanism that described main shaft and described cutter couple together with described cutter 2.
Contiguous block 201 inserts both be connected and fixed of connection chambers 101 interior realizations, connection chamber and contiguous block can be quadrangles, pentagon, the polygon mats such as hexagon, connection chamber is corresponding with it polygonal hole, contiguous block and connection chamber both can be equilateral, also can be unequal-sided, in the present embodiment, described connection chamber 101 is quadrilateral hole, described contiguous block 201 is the quadrangle piece, and for so that both better connect, described tetragonal contiguous block 201 begins the wedge that broadens gradually from the top down for width, like this, when contiguous block inserts in the connection chamber, because width increases gradually, so that produce the effect of an engaging, connect more firm between the two.
When main shaft 1 is connected with cutter by connection chamber with after contiguous block is connected, in order to prevent that both from connecting rear disengagement, so also need anticreep bindiny mechanism, described anticreep bindiny mechanism comprises the adapter sleeve 3 that is sleeved on the described main shaft 1, be fixed on the baffle plate 4 on the described main shaft 1 and be set with on the described main shaft described adapter sleeve 3 to the spring 5 that presses down, spring is arranged between baffle plate and the adapter sleeve, be sleeved on the main shaft, one end withstands on the baffle plate 4, the other end withstands on the adapter sleeve 3, with adapter sleeve to pressing down, baffle plate can adopt snap ring, fixing back-up ring and so on, can also directly utilize the crumb loading cover to do baffle plate, simultaneously, be provided with a plurality of radial holes 102 that spheroid 6 is installed at described main shaft 1, the quantity of radial hole can be 3,4,5,6, even more, present embodiment is 3, uniform setting, spheroid generally adopts steel ball, in order to cooperate with it, described cutter 2 is provided with the draw-in groove 202 that matches with described spheroid 6, cooperate for the ease of processing with spheroid, in the present embodiment, draw-in groove is to extend and the endless groove of formation along the whole outer circumference surface of described cutter, and and described adapter sleeve 3 is provided with a taper hole 301 that under the spring-force driven dual of described spring 5 described spheroid 6 is pressed in the described draw-in groove 202, the opening of taper hole increases from top to bottom gradually, the cone-shaped inner surface of taper hole 301 contacts with steel ball, under the spring-force driven dual of spring, steel ball is pressed in the draw-in groove of ring-type, realize that main shaft is connected connection with cutter, can not come off, when needs are changed cutter 2, arrest adapter sleeve with hand and upwards carry, overcome the spring force of spring, this time, the conical surface and the steel ball of taper hole broke away from, and with hand cutter were moved down, with mutually outer promotion of steel ball, break away from draw-in groove, cutter takes apart, and this process is very rapid, in the time of the needs mounting cutter, with hand adapter sleeve is upwards carried again, cutter is inserted, unclamp hand, steel ball is snapped into draw-in groove.
Embodiment 2, see accompanying drawing 6, in the present embodiment, described anticreep bindiny mechanism comprises the bulb plunger 7 that is installed on the described main shaft, described cutter is provided with the hole clipping 203 that matches with described spheroid plunger, and is same, and hole clipping is the annular groove that extends along the whole outer circumference surface of described cutter.The quantity of hole clipping and bulb plunger is determined according to actual conditions, is generally 3, in the through hole 103 of the main shaft that the bulb plunger is installed.All the other are with embodiment 1, and than embodiment 1, the present embodiment structure is simpler.
More than explanation only is explanation of the invention, so that complete enforcement this programme of those of ordinary skills' energy, but be not limitation of the present invention, those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, these all are not creative modifications.But as long as in claim scope of the present invention, all be subject to the protection of Patent Law.
