A kind of dust guard of computer jacquard
Technical field
The present invention relates to the ancillary equipment fields of computer jacquard, are specifically related to a kind of dust-proof dress of computer jacquard
It sets.
Background technique
Knitting machine, as the term suggests it is exactly the machine for weaving knitted fabric.Knitting machine can be divided into flat by the form of needle bed
Type knitting machine and circular knitter, and circular knitter can be divided into large-scale circular knitting machine and miniature circular knitting by size
Machine, i.e., so-called large circle machine and small circular knitting machine.It is mounted with corresponding full-jacquard mechanism with advances in technology, on knitting machine simultaneously, it is real
Existing knitting machine carries out jacquard weave to fabric simultaneously in the weaving process, and the knitting needle circular knitting machine with jacquard weave function is known as jacquard circle knitting machine.
Jacquard circle knitting machine adhesive dust on unavoidable yarn during knitting machine weaving, and dust accretions dials on knitting machine
Or will cause knitting needle in the braiding adjustment seat of bottom cylinder or weave the abrasion of knitting cam in adjustment seat, to influence the volume of fabric
Knit quality, it is therefore necessary to be improved.
Summary of the invention
The purpose of the present invention aims to solve the problem that problem of the existing technology, provide one kind can be reduced dust enter braiding adjust
Seat reduces the abrasion of knitting cam in braiding adjustment seat, to improve the dust guard of the computer jacquard of weaving textile quality.
The present invention relates to a kind of dust guards of computer jacquard, including the transmission being connected by gear with jacquard main shaft
Axis, further includes the dust-proof mechanism being arranged in above the braiding adjustment seat of jacquard, and the dust-proof mechanism includes being arranged in the volume
Knit the dust excluding plate above adjustment seat, the rotor plate being hinged in the dust excluding plate, the dust-collecting box being arranged in below the rotor plate,
Rotary shaft and the fixed driven wheel of differential that is set in described rotary shaft one end of the sleeve in rotor plate side, the middle part of dust excluding plate at
Type has through slot, and the lateral wall of rotor plate and the inner sidewall of the through slot fit, and forms grafting on the dust excluding plate of through slot side
Slot, rotary shaft sleeve are arranged with torsional spring in the inserting groove in rotary shaft, one end of the torsional spring is fixed on the rotary shaft,
The other end is fixed on the inner wall of inserting groove;
The transmission shaft is located at the side of the driven wheel of differential, forms external splines on the lateral wall of transmission shaft, transmission
Drive bevel gear corresponding with driven wheel of differential is arranged on axis, the middle part of the drive bevel gear has through-hole, described logical
There is the internal spline cooperated with the external splines, the top of transmission shaft is equipped with the lifting air of piston rod straight down on the inner wall in hole
Cylinder, the piston-rod lower end of the lifting cylinder are fixedly connected with lifter plate, and the lower end of the lifter plate is hinged with rotating bar, described
The sleeve hole with transmission shaft cooperation is formed in the middle part of the bottom surface of rotating bar, sleeve hole sleeve is in the upper end of transmission shaft, rotation
The bottom of bar is fixed on the upper surface of drive bevel gear.
By above-mentioned technical proposal, in the use of the present invention, computer jacquard works, the anti-of the top of adjustment seat is woven
Dirt mechanism carries out proofing dust and protecting to braiding adjustment seat, and specifically, the dust excluding plate and rotor plate of dust-proof mechanism are in braiding adjustment seat
Top, the dust that will be fallen in originally in braiding adjustment seat stops, and dust accumulates on rotor plate.Transmission shaft drives actively simultaneously
Bevel gear rotation, when the dust accretions on rotor plate to a certain extent when, lifting cylinder starting, drive lifter plate move up, go up and down
The dynamic rotating bar thereon of strip moves up, and rotating bar drives the drive bevel gear for being fixed on its lower end to move up, until drive bevel gear
It is meshed with driven wheel of differential.Drive bevel gear is arranged by the cooperation of the external splines on the internal spline and transmission shaft in its through-hole
On transmission shaft, so that drive bevel gear is during moving up simultaneously as transmission shaft rotates together.Work as active conical tooth
When wheel is engaged with driven wheel of differential, drive bevel gear drives driven wheel of differential to rotate together, and driven wheel of differential drives rotary shaft to turn
Dynamic, rotary shaft drives rotor plate thereon to rotate around rotary shaft, rotates down rotor plate in the through slot of dust excluding plate,
Thus dust on inclined rotor plate completes the collection of accumulation dust since gravity is fallen into dust-collecting box.On rotor plate
Dust cleared up after, the piston rod of lifting cylinder stretches, and drives lifter plate, rotating bar and drive bevel gear to move down, to make
Drive bevel gear is detached from driven wheel of differential again, and at the same time, rotary shaft and rotor plate revolve under the action of torsional spring restores elastic force
Turn, rotor plate is rotated up in through slot around rotary shaft, sets back fit with the inner wall of through slot again.Later, when turn
When dust on movable plate is accumulated again, above step is repeated, the braiding adjustment seat of computer jacquard can be avoided to the full extent
Upper dust stratification improves weaving quality.
Through the above scheme, dust guard of the invention can be reduced dust and enter braiding adjustment seat, reduce braiding adjustment seat
The abrasion of upper knitting cam, to improve weaving textile quality.
As a preference of the above scheme, the rotor plate side be arranged in the inserting groove, on rotor plate at
Type has rotation slot, and the fixed sleeve of the rotary shaft in the rotation slot, stretch out rotation slot and stretch out grafting by one end of rotary shaft
