Specific embodiment
The related details and working principle of the embodiments of the present invention and embodiment are described with reference to the accompanying drawing.This kind
Rubber band spreading mechanism, includes drive plate, swing arm 70 and scraping wings 63, and the drive plate includes price fixing 64 and turntable 65, i.e.,
Turntable can be rotated relative to price fixing, and the price fixing 64 is mounted on mounting plate 61, and the mounting plate is movably arranged in rack, fixed
Packing adjusts its position on the rack according to the position of material, sees attached drawing 1, mounting groove 62, institute are offered on the mounting plate 61
It states mounting plate to be mounted on the rack by bolt, the bolt passes through mounting groove and connect with rack.
One end of the swing arm 70 and price fixing 64 are hinged, and the two hinged place is hinge joint 67, and the other end of the swing arm is pacified
Axis 72 is expected equipped with support, offer arc-shaped guide groove 69 in the swing arm, be equipped on the turntable and be slidably matched with guide groove
Several groups, and peripherally disposed, circumferencial direction of the swing arm along price fixing is arranged in positioning pin 68, the positioning pin and swing arm
Setting, positioning pin are arranged along the circumferencial direction of turntable, and the price fixing and turntable are then arranged concentrically；The support expects axis 72 to turntable
When center is gathered, 71 sets of rubber band can be made on support material axis, after rubber band is put well, turntable 65 is rotated relative to price fixing, positioning pin
68 move in guide groove therewith, swing out swing arm centered on hinge joint 67, and support material axis 72 spreads out, and rubber band 71 is supportted
It opens, and for material insertion, not only distracted range is big for the positioning pin 68, four groups of the setting of swing arm 70, but also structure is relatively smart
Letter, if swing arm is along the circumferential direction uniformly arranged, rubber band strut it is square, due to bag body fold after be in cuboid, because
This rubber band strut be rectangle it is most appropriate, pressure rubber band is strutted in sufficiently large square, be easy to cause rubber band to be broken；This
Four swing arms in embodiment are not to be uniformly arranged, that is to say, that the central point that four swing arms are swung not is to be uniformly arranged
, see attached drawing 1 and attached drawing 2, for ease of description, the interface point of four swing arms is successively named as hinge joint 1, hinge joint
2 672, hinge joint 3 673 and hinge joint 4 674, the included angle A that the central point of the hinge joint one, hinge joint two and price fixing is formed
Less than 90 degree or it is greater than 90 degree, the angle of included angle B and included angle A that the central point of same hinge joint three, hinge joint four and price fixing is formed
Degree is consistent, and such rubber band is rectangle after strutting.After the rubber band struts, material is inserted into the distracted circle of rubber band, the pusher
Plate 63 then releases the rubber band 71 covered on support material axis, and rubber band contraction covers on material, so realizes and ties up.
In the present embodiment, the price fixing 64 and turntable 65 are ring-type, and the price fixing is outer ring, and the turntable is inner ring,
The outer ring is set in outside inner ring, and the inner ring is connect with its driving part rotated in outer ring is driven, in order to reduce inner ring
Friction between outer ring, is provided with ball between the inner ring and outer ring, i.e., the inner peripheral surface of the described outer ring and inner ring it is outer
Periphery opens up fluted, and the ball is placed in groove, and such inner ring is more smooth with respect to outer ring rotating, is not drawn in figure
Out；The driving part can use cylinder 74, and the piston rod of the cylinder 74 stretches out, and push inner ring 65 with respect to 64 inverse time of outer ring
Needle rotation, swing arm 70 are swung out centered on hinge joint, and the support material axis 72 scatter, and rubber band 71 is softened, the cylinder
74 piston rod retraction, the inner ring are rotated clockwise with respect to outer ring, the swing arm inside circle center centered on hinge joint 67
Position is swung, and the support material axis 72 is gathered.
The scraping wings 63 need to will be set on support material axis and distracted rubber band 71 has been released, makes rubber band sleeve on material
As long as thus scraping wings is inserted between rubber band and swing arm after rubber band struts and releases rubber band, when rubber band does not strut,
Scraping wings can be set in the side of drive plate, the present embodiment, in order to which structure is more compact, reduce cost, the scraping wings
63 are arranged in swing arm 70 and strut between rubber band 71, if rubber band 71 is bonded with swing arm 70, scraping wings 63 may be in swing arm and skin
The side of muscle cannot say that rubber band pushes in the bag body folded, to prevent this phenomenon from occurring, the mounting portion of the support material axis
76 surface has gradient, sees that attached drawing 3, the support material axis are divided into mounting portion 76 and support material portion 77, connect close to support material axis and swing arm
Connecing end is mounting portion, and the surface of the mounting portion has taper with gradient, that is, mounting portion, and the support material portion is column, rubber band
When hanging on support material axis 72 and being softened, because there is mounting portion taper to make rubber band that can be automatically moved into support material portion 77, thus
Ensure scraping wings 63 between swing arm and distracted rubber band.Offered on the scraping wings 63 for the mobile channel 66 of support material axis with
And the notch 73 for material insertion, the scraping wings are connect with its actuator moved left and right is driven, the actuator can be adopted
With cylinder 75, the utility model only needs an actuator can be so that rubber band is detached from support material axis, and the channel 66 on scraping wings
Do not influence the operation of swing arm then, and the setting of notch 73 is then inserted through scraping wings for material, that is to say, that material can be worn
Scraping wings 63 and price fixing 64 and turntable 65 are crossed, when the center of material is aligned with rubber band 71, scraping wings 63 is pushed on support material axis
Rubber band 71, rubber band is detached from 72 sets of axis of support material on material, and rubber band sleeve is in the middle position of material, tie up in this way it is stronger,
Stablize.
