Description
Technical Field
The utility model relates to a paper cutting equipment, concretely relates to paper cutter actuating mechanism's clutch.
Background
Paper cutter mainly used cuts of all kinds of paper, its theory of operation is the cutting off that realizes the paper through the lift of control cutter, at present, paper cutter on the market, the action of its cutter can adopt for example a lot of different mechanisms such as cylinder or motor drive mechanism to drive, but discover in the in-service use process, adopt cylinder drive's paper cutter, drive power is obvious relatively poor and life is lower, and adopt motor drive's all kinds of actuating mechanism, when the motor shuts down, still there is certain rotation inertia, this will bring the power of continuing the action for cutter, the action that leads to the cutter is not so accurate, influence the quality that cuts of paper.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a can realize the quick separation and reunion of cutter drive mechanism and power supply, guarantee the accurate nature of cutter action, effectively improve the paper cutter actuating mechanism's of its cut paper quality clutch.
Therefore, the utility model discloses an adopt following scheme to realize:
paper cutter actuating mechanism's clutch, have with the blade holder transmission be connected the worm wheel, with worm wheel meshing's worm, install the power wheel on the worm through the bearing, its characterized in that: the worm is sequentially provided with a cylinder body and a clutch disc, the worm is rotatably installed in the cylinder body, the clutch disc is connected to the worm through a key, one surface, close to the clutch disc, of the power wheel is provided with a first friction plate, the cylinder body is provided with an oil cavity, a piston body is arranged in the oil cavity and is movably connected with the clutch disc, one side, close to the clutch disc, of the cylinder body is provided with a second friction plate, the cylinder body is provided with an oil inlet communicated with the oil cavity, one side, opposite to the first friction plate, of the clutch disc is provided with a reset spring, two ends of the reset spring respectively abut against the clutch disc and a baffle, and the baffle is connected with the worm.
The baffle is fixed on the worm by a clamp spring.
The piston body is connected with one end of a buffer spring, and the other end of the buffer spring is connected inside the cylinder body.
Adopt above-mentioned technical scheme, the utility model discloses an advantage does: drive the piston body action through letting in hydraulic oil toward the oil intracavity, can drive the clutch disc and remove and compress tightly with the first friction disc on the power wheel, compress reset spring simultaneously, the clutch disc rotates and drives worm and worm wheel rotation under the effect of frictional force, and then drive blade holder and cutter and go up and down, after stopping supplying liquid, the clutch disc moves back and separates with first friction disc under reset spring's drive, inertia after having avoided the motor stall transmits the clutch disc on, and simultaneously, the clutch disc can compress tightly with the second friction disc, and brake the clutch disc under the effect of frictional force, make the quick stall of worm and worm wheel, guarantee the accurate nature of cutter action, effectively improve the quality of cutting of paper.
Drawings
The utility model discloses there is following figure:
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a cross-sectional view of the worm gear of the present invention;
Fig. 3 is a cross-sectional view taken at the point B-B in fig. 2.
Detailed Description
As shown in the figure, the utility model discloses a clutch device of a cutter driving mechanism of a paper cutter, which comprises a worm wheel 3 in transmission connection with a cutter holder 1, a worm 4 meshed with the worm wheel 3, a power wheel 5 arranged on the worm 4 through a bearing, the worm wheel 3 is eccentrically hinged with one end of a swing rod 2, the other end of the swing rod 2 is hinged with the cutter holder 1, a cylinder body 12 and a clutch disc 7 are sequentially arranged on the worm 4, the worm 4 is rotatably arranged in the cylinder body 12, the clutch disc 7 is connected on the worm 4 through a key, one side of the power wheel 5 close to the clutch disc 7 is provided with a first friction plate 6, the cylinder body 12 is provided with an oil cavity 10, the cylinder body 12 is provided with an oil inlet communicated with the oil cavity 10, a piston body 9 is arranged in the oil cavity 10, the piston body 9 is movably connected with the clutch disc 7, a groove is arranged, the other end of the buffer spring 15 is connected inside the cylinder body 12, and the buffer spring 15 can buffer the pushing force of the piston body 9 under the action of hydraulic pressure, so that the transmission between the piston body 9 and the clutch disc 7 is more stable, and when the liquid supply is stopped, the buffer spring 15 can also drive the piston body 9 to move back in time, so that the piston body 9 can achieve the buffering effect. In the embodiment, the baffle plate 13 is fixedly connected to the worm 4 through a snap spring 14, when hydraulic oil is introduced into the oil cavity 10, the piston body 9 can be driven by the hydraulic pressure to push the clutch plate 7 to be tightly pressed with the first friction plate 6 and compress the return spring 8, the transmission between the power wheel 5 and the clutch plate 7 is realized through the friction force and drive the clutch plate 7 to rotate, then the tool apron 1 is driven to move through the transmission of the worm wheel and the swing rod 2, after the liquid supply is stopped, the clutch plate 7 is not stressed by the pressure of the piston body and moves back under the driving of the return spring 8 to be separated from the first friction plate, and the rotational inertia after the rotation of the motor is stopped is prevented from being transmitted to the clutch plate, and the clutch disc 7 is pressed tightly with the second friction plate 11 by the acting force of the reset spring 8, and the clutch disc 7 is braked and stopped under the action of the friction force, so that the worm and the worm wheel are stopped quickly, the accuracy of the action of the cutter is further ensured, and the cutting quality of paper is effectively improved.
