Specific embodiment
The invention will be further described With reference to embodiment.
Referring to Fig.1-3, the present invention novel wire feed machine continuously printed with fracture that reloads automatically includes the motor being sequentially arranged
1, wire feed rolls mounting plate 2, bearing mounting plate 3 and fixed plate 4；This four parts are attached by removably.
Wherein, gear 5 is arranged on the output shaft of the motor 1, the fixed plate 4 is equipped with motor output shaft punched out
41.The wire feed rolls mounting plate 2 is equipped with gear punched out 21, be also equipped on the wire feed rolls mounting plate 2 upper wire feeding hose wheel 6 and under
Wire feed rolls 7, the gear 5 are engaged with upper and lower wire feed rolls, are driven by gear so that the equidirectional same speed of wire feed rolls turns up and down
It is dynamic.
The bearing mounting plate 3 is equipped with wire feed channel 31, and the upper wire feeding hose wheel receiving hole 35 positioned at 31 side of channel is under
Wire feed rolls receiving hole 36, and upper mounting groove 33 and lower mounting groove 34 positioned at 31 other side of channel.In upper and lower mounting groove respectively
Equipped with upper bearing (metal) frame 10 and lower bearing bracket 11.10 one end of upper bearing (metal) frame is equipped with the upper bearing (metal) 8 cooperated with upper wire feeding hose wheel 6, upper bearing (metal)
The other end of frame 10 is connected by spring 12 with upper 33 side wall of mounting groove；11 one end of lower bearing bracket is equipped with to be cooperated with lower wire feeding hose wheel 7
Lower bearing 9, the other end of lower bearing bracket 11 is connected by spring 13 with lower 34 side wall of mounting groove.
Wire feed channel 31 in the present invention is divided for two sections, and channel upper section width is big, and lower section width is small；Channel upper section with
Upper mounting groove 33 and upper wire feeding hose wheel receiving hole 35 are connected to, and channel upper section can accommodate multi-filament material side by side simultaneously, and be pressed by upper bearing (metal) 8
Tight silk makes silk closely upper wire feeding hose wheel 6, after a silk downlink close to upper and lower wire feed rolls is detached from wire feed channel upper section
The upward wire feed rolls 6 under the promotion of spring 12 of upper bearing (metal) 8 is mobile and spare silk is pushed to and abutted upper wire feeding hose wheel 6, under channel
Section is connected to lower mounting groove 34 and lower wire feeding hose wheel receiving hole 36, and channel lower section only allows a silk to pass through, and is compressed by lower bearing 7
This root silk makes the silk closely lower wire feeding hose wheel 7, remaining spare silk still rests in the upper section of channel.
The present invention on bearing mounting plate by opening up wire feed channel 31 wide at the top and narrow at the bottom, so that channel upper section can be same
When accommodate multi-filament material side by side, and channel lower section only allows a silk to pass through, when the silk of closely wire feed rolls is used up into tail
When the material stage, tailing is detached from upper wire feeding hose wheel 6, single to travel out wire feed channel lower section by the driving of lower wire feeding hose wheel 7；Meanwhile upper bearing (metal) 8
Spare silk is pushed to upper wire feeding hose wheel 4, due to the effect of spring, standby material can be adjacent to rapidly upper wire feeding hose wheel, standby material starting row
Into standby material travel speed is identical as precursor material travel speed, after standby material enters the driving range of lower wire feeding hose wheel 7, by upper wire feeding hose
Driving charging, the process make silk and being connected for standby material rapid jointly for wheel 6 and lower wire feeding hose wheel 7, guarantee to go out in print procedure
Silk continuous-stable, reloads and continuously prints automatically to realize.
The case where channel upper section can while accommodate 4 silks side by side is shown in Fig. 4, certain channel upper section can also simultaneously simultaneously
5,6,7 are set in discharge, and even more silks, then according to silk service condition, subsequent silk, which serially enters, to be sent
Filamentous state, to meet the needs of printing.This means that the present apparatus can automatically continuously use multireel silk, and in contingency
When fracture happens, prepare the spare silk of more emergency supplies, realizes reloading and continuously beat automatically for the present apparatus
The function of print.
It is capable of clamping 1 silk in order to guarantee not only to be capable of clamping multi-filament material between upper bearing (metal) 8 and upper wire feeding hose wheel 6, and is guaranteed
The smooth downlink of silk, the spring 13 that is connected with upper bearing (metal) frame stretches stroke greater than the spring being connected with lower bearing bracket in the present invention
14,13 elastic force of spring being connected with upper bearing (metal) frame is less than the spring 14 being connected with lower bearing bracket.It is connected with upper bearing (metal) frame
The small purpose of spring force is to allow silk by upper wire feeding hose wheel drive downlink, while the friction reduced again with adjacent standby material hinders
Power, lower spring force is larger, realizes main driving silk downlink function.
Upper and lower bearing bracket stand of the invention includes the bearing bracket stand ontology for installing bearing, and portion on the body is arranged
Upper draw runner and the lower draw runner of body lower part is set；The upper and lower mounting groove is equipped with the sliding way cooperated with upper and lower draw runner
And glide path.It is respectively equipped with forward and backward draw runner before and after the ontology of upper and lower axle bolster in the present embodiment, is set in the fixed plate 4
There is the slideway with the advancing slip item cooperation of upper lower fixed frame, on the one hand facilitates the movement of bearing, on the other hand make device compact, volume
It is small.Bearing bracket stand ontology is equipped with installation axle, and bearing is installed on the mounting shaft, and silk is contacted with bearing outside surface.
Upper and lower wire feed rolls in the present embodiment is made of front wheels and rear wheels, and the diameter of the front-wheel is less than the straight of rear-wheel
Diameter, wherein the rear-wheel of upper and lower wire feed rolls is engaged with gear, the front-wheel of the upper and lower wire feed rolls is contacted with silk, passes through gear band
Dynamic rear-wheel and then drive front-wheel drive silk downlink, are arranged to this structure for upper and lower wire feed rolls, can make front-wheel deceleration silk
Material, keeps silk travel distance more acurrate, in addition, can also reduce the volume of whole device.Certainly, upper and lower wire feed rolls may be tooth
Colyliform which is provided with the gear teeth with gear cooperation.
The upper and lower bearing is rolling bearing, and the inner ring of rolling bearing is fixedly arranged in the installation axle of bearing bracket stand ontology, is rolled
The outer ring of bearing is free to rotate, on the other hand smooth downlink of the rolling bearing setting one side to guarantee silk can guarantee
Silk is pressed on wire feed rolls by bearing.
The wire feed rolls mounting plate, bearing mounting plate and fixed plate in the present embodiment are equipped with matches with motor bolt hole
The screw hole of conjunction.This four part is connected by bolt.Wherein wherein set that there are two dormant bolts on motor on wire feed rolls mounting plate
Hole is cooperated with the bolt hole of motor side.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than is limited；Although referring to aforementioned reality
Applying example, invention is explained in detail, for those of ordinary skill in the art, still can be to aforementioned implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these are modified or replace
It changes, the spirit and scope for claimed technical solution of the invention that it does not separate the essence of the corresponding technical solution.
