Abstract

The utility model discloses a device for haircut and wool-shearing. An upper casing 1 and a lower casing 4 are fastened together after the upper casing 1 and the lower casing 4 are jointed with each other; an upper blade 12 and a lower blade 11 are installed at the front end of the lower casing 4; by making use of shaft coupling 3 and a speed reducer 2, a motor 5 can drive an eccentric wheel 15 to rotate; one end of a shifting fork 13 is contacted with the outer circle of the eccentric wheel 15, and the other end of the shifting fork 13 is inserted in a hole of the upper blade 12; thus, the shifting fork 13 can use an axial line of a pin 14 as a center to swing when the eccentric wheel 15 rotates, so the upper blade 12 can be driven to do reciprocating shearing motion. An impeller 6 which is installed at the other end of the motor 5 is matched with a wind admitting passage 7 and a wind exhausting passage 16, so the utility model also has the dreg-sucking function and the dreg-removing function.

Description

The haircut shearing machine

The utility model relates to and a kind ofly is used to get a haircut or the instrument of cropping.

In the prior art, the instrument of haircut or cropping generally has two kinds, and a kind of is manual hair clipper, though it is simple in structure, cost is low, but must constantly clutch and unclamp and cut handle with hand in use, make feel, thereby continuous operation for a long time to fatigue; Another kind is an electric haircutting scissors, and its structure and operation principle are the electromagnet with an alternate energisation and outage, alternately attracts and discharges an iron plate, makes iron plate do teeter, and an end button blade of iron plate connects, thereby drives the blade traverse motion.Though this kind electric haircutting scissors has alleviated labour intensity, also there is following shortcoming simultaneously: the first, must adjust the distance between iron plate and the electromagnet, otherwise vibration and noise are all very big, and adjustment is often very difficult, so use very inconvenient constantly.The second, because the frequency of its structures shape blade swing is too high, reach per second 50 times.And actual per second only need can satisfy use 10～15 times, thereby causes the waste of the energy.

The purpose of this utility model provides the haircut and the cropping instrument of a kind of health easy to use, energy savings.

In order to achieve the above object, this haircut shearing machine mainly is made up of upper casing, lower casing, cutter, bottom knife, motor, decelerator, eccentric wheel and shift fork.The involutory back of upper casing and lower casing tightens together with screw, cutter and bottom knife are installed in the front end of lower casing, motor, decelerator, eccentric wheel, shift fork are installed in the cavity between upper casing and the lower casing, motor drives the eccentric wheel rotation that is installed on the reducer output shaft by decelerator, one end and the eccentric cylindrical of shift fork contact, the other end inserts in the hole of cutter, drive the shift fork teeter during eccentric wheel rotation, shift fork drives cutter and make reciprocal shearing motion on bottom knife.

Can also install impeller at the other end of motor reel, correspondingly on upper casing and lower casing, be shaped on air inlet duct and exhausting duct therewith, on lower casing, be shaped on slag trapping chamber, mud hole air inlet and filter screen.The end of accurate cutter during one end of air inlet duct, the other end and slag trapping chamber, impeller communicate; One end and the impeller of exhausting duct communicate, and the other end leads to outside the casing.

Adopted technique scheme,,, used easily so vibration and noise are all very little owing to be reciprocating with eccentric wheel drive shift fork.When design, can select simultaneously the motor of suitable rotating speed and suitably the decelerator of gearratio control the cutter swing frequency in optimum value, thereby reduce energy resource consumption, than prior art energy-conservation about 50%.If the other end at motor reel is installed impeller, and on casing, set up air inlet duct and exhausting duct, also can when haircut, avoid the hair slag to fall in the collar.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the overall installation diagram of haircut shearing machine.

Fig. 2 is subjectivity figure, vertical view and the left view that eccentric wheel 15 and shift fork 13 are combined.

Fig. 3 is the front view that upper casing 1, lower casing 4 and impeller 6 are combined.

Fig. 4 is the vertical view after Fig. 3 removes upper casing 1.

Fig. 5 is A-A, B-B, C-C and the D-D cut-away view of Fig. 3.

The haircut shearing machine mainly is made up of upper casing 1, lower casing 4, cutter 12, bottom knife 11, motor 5, shaft coupling 3, decelerator 2, eccentric wheel 15, shift fork 13, pin 14, impeller 6, filter screen 8, ash gate 10 in Fig. 1.Upper casing 1 and lower casing 4 involutory backs tighten together with screw.Cutter 12 and bottom knife 11 are installed in the front end of lower casing 4, and shift fork 13, eccentric wheel 15, decelerator 2, motor 5, impeller 6 are installed in the cavity of upper casing 1 and lower casing 4 involutory back formation successively.Motor 5 drives eccentric wheel 15 rotations by shaft coupling 3 and decelerator 2.One end of shift fork 13 and the cylindrical of eccentric wheel 15 contact, and the other end inserts in the hole of cutter 12, during eccentric wheel 15 rotations, drive cutter 12 by shift fork 13 and make reciprocal shearing motion on bottom knife 11.

Fig. 2 has further reflected the structure of eccentric wheel 15 and shift fork 13.The head of shift fork 13 is " U " font among Fig. 2, and flute profile eccentric wheel 15 is clipped in wherein.Shift fork 13 usefulness pins 14 are installed on the lower casing 4, and hole on the shift fork 13 and pin 14 are matched in clearance, so shift fork 13 can be around the axis swing of pin 14.The afterbody of shift fork 13 inserts in the hole of cutter 12, and when eccentric wheel rotated, the head and the afterbody work that drive shift fork 13 were the reciprocally swinging at center with pin 14 axis, make reciprocal shearing motion thereby drive cutter 12.

Fig. 3, Fig. 4 and Fig. 5 have further reflected the structure and the interaction of air inlet duct 7, exhausting duct 16 and impeller 6.On lower casing 4 and upper casing 1, be shaped on air inlet duct 7 and exhausting duct 16 among the figure, on lower casing 4, be shaped on slag trapping chamber 9, ash gate 10, air inlet 17 and filter screen 8.The structure of impeller 6 is identical with common dust catcher with operation principle.When 6 rotations of motor 5 impeller, after the hair disintegrating slag that air flow A and air is cut was inhaled into slag trapping chamber 9 from air inlet duct 7 together, air communication screen pack 8 and air inlet 17 entered exhausting duct 16 from impeller 6 bottoms and are discharged from; The hair disintegrating slag is intercepted by filter screen 8 and drops in the slag trapping chamber 9.After every work a period of time, open the ash gate 10 that is positioned at slag trapping chamber 9 bottoms, the hair disintegrating slag can be discharged.

The utility model is except above-mentioned most preferred embodiment, and some other structures of part can also have some variations, for example: slag absorbing, slag-draining devices such as impeller 6, air inlet duct 7, exhausting duct 16, slag trapping chamber 9, ash gate 10, filter screen 8, air inlet 17 can be set; Exhausting duct 16 can be arranged on the bottom of lower casing 4 and ash gate 10 is located at side of lower casing 4 etc., and all these change all among protection domain of the present utility model.
