The reciprocating double-blade cutter comprises a shell, a driving device, a power shaft and a first main shaft, wherein a first eccentric wheel is arranged at the left end of the power shaft; a first front shifting rod and a first rear shifting rod of which the left ends are fixedly connected with the first main shaft are arranged in front of and behind the first eccentric wheel respectively; a first blade is fixedly connected to the lower end of the first main shaft; a second main shaft is rotatably sleeved on the first main shaft; a second blade is fixedly connected to the lower end of the second main shaft; a second eccentric wheel is also arranged at the left end of the power shaft; a second front shifting rod and a second rear shifting rod of which the left ends are fixedly connected with the second main shaft are arranged in front of and behind the second eccentric wheel respectively; and the first eccentric wheel and the second eccentric wheel have opposite eccentric directions. Compared with the prior art, the reciprocating double-blade cutter can offset unidirectional force generated during the reciprocating movement of the blades when the blades cut an object, so that when cutting an object, the reciprocating double-blade cutter has small vibration, is easy to hold by an operator, and has high safety and high cutting efficiency.
Description
Technical field
The present invention relates to reciprocating cutter, especially a kind of reciprocating double-blade cutter.
Background technology
Existing reciprocating cutter, as depicted in figs. 1 and 2, generally include housing 1, be arranged on the drive unit 2 in described housing 1, horizontally set the line shaft 3 driven by described drive unit 2 and longitudinally arrange and its underpart passes the main shaft 6 of housing 1, an eccentric wheel 4 is provided with in the left part of described line shaft 3, the front and back of described eccentric wheel 4 be respectively equipped with left end be fixedly connected with described main shaft 6 before driving lever 501 and rear driving lever 502, be fixedly connected with blade 7 in the lower end of main shaft 6.Drive unit 2 drives line shaft 3 to be with movable eccentric wheel 4 to rotate, eccentric wheel 4 drives front driving lever 501 and rear driving lever 502 swing, by the swing of front driving lever 501 and rear driving lever 502, drive main shaft 6 to hocket to rotate and reverse, thus drive be fixedly arranged on the blade 7 of main shaft 6 lower end cutting edge before and after reciprocally swinging, for cutting object.
This structure of existing reciprocating cutter, drive a reciprocating knives to cut object with single eccentric wheel, its defect: one is can produce a unidirectional force when cutting, described reciprocating cutter is made to produce larger vibration in the process of cutting object, so that affect cutting accuracy, and easily cause operator's hand fiber crops, feel tired, very easily cause fault; Two is that cutting speed is not high, if increase cutting speed, must improve driving mechanism rotating speed, and rotating speed increase makes vibration increase further, because which limit the raising of cutting speed.
Summary of the invention
The object of the invention is to: a kind of reciprocating double-blade cutter is provided, blade can be offset at the unidirectional force that produces of cutting object, make reciprocating cutter vibrate when cutting object little, efficiency is high, security good.
For achieving the above object, the present invention can take following technical proposals:
A kind of reciprocating double-blade cutter of the present invention, comprise housing, be arranged on the drive unit in described housing, horizontally set the line shaft driven by described drive unit, and longitudinally to arrange and its underpart passes the first main shaft of housing, the first eccentric wheel is provided with in the left part of described line shaft, described first eccentric front and back be respectively equipped with that left end is fixedly connected with described first main shaft first before driving lever after driving lever and first, the first blade is fixedly connected with in the lower end of the first main shaft, rotatingly on the first main shaft be arranged with the second main shaft, the second blade is fixedly connected with in the lower end of this second main shaft, described first blade (7) is overlapping with the cutting edge of the second blade (7 '), the second eccentric wheel is also provided with in the left part of described line shaft, described second eccentric front and back be respectively equipped with that left end is fixedly connected with described second main shaft second before driving lever after driving lever and second, described first, second eccentric eccentric direction is contrary, by the rotation of line shaft, the reciprocally swinging kind of drive before and after the first eccentric wheel and the first forward and backward driving lever are formed, after the second eccentric wheel and second, front driving lever forms the reciprocally swinging kind of drive afterwards.
Described first eccentric wheel and the second eccentric wheel are structure as a whole.
Described first eccentric wheel, the second eccentric wheel and line shaft are structure as a whole.
Described line shaft is two sections of bent axles, and described first eccentric wheel, the second eccentric wheel are made up of the torus be arranged at respectively on described bent axle.
The left part of described first forward and backward driving lever crosses and is integrally formed structure, both right parts extend both sides before and after the first eccentric wheel respectively vertically downward, second forward and backward driving lever is positioned at the below of the first forward and backward driving lever, the left part of the second forward and backward driving lever crosses and is integrally formed structure, and right part extends both sides before and after the second eccentric wheel respectively vertically upward.
Compared with prior art the invention has the beneficial effects as follows: on described line shaft, be directly provided with the first eccentric wheel and the second eccentric wheel owing to adopting, at outer rotating sheathed second main shaft of traditional the first main shaft that the first blade is housed, the lower end of the second main shaft has been fixedly connected with the second blade, utilize the rotation of line shaft, described first eccentric wheel rotates, driving lever before alternately stirring first, after first, driving lever forward, swing backward, namely the reciprocally swinging kind of drive before and after forming, before first, the left end of rear driving lever is all fixedly connected with the first main shaft, therefore before first, rear driving lever can together before and after reciprocally swinging, first main shaft also replaces positive and negative rotation thereupon and drives the first reciprocating knives of its lower end, simultaneously, after second eccentric wheel drives second, front driving lever is rear front reciprocally swinging together, namely the reciprocally swinging kind of drive before after forming, because described two eccentric eccentric directions are contrary, so before first, before the swaying direction of rear driving lever and second, the swaying direction of rear driving lever is contrary, accordingly, first main shaft is also contrary with the rotation direction of the second main shaft, finally make the first blade contrary with the cut direction of the second blade, this structure compared with prior art, the unidirectional force that when cutting object, reciprocating knives produces can be offset, the present invention is vibrated little when cutting object, operator easily holds, security is good, simultaneously, double blade cutting efficiency is high, little owing to vibrating when cutting object, balance is good, can also improve the speed of reciprocating cutting further.
