A kind of computer jacquard with dust guard
Technical field:
The present invention relates to the technical field of textile machine, be specifically related to a kind of computer jacquard with dust guard.
Background technology:
Knitting machine, as the term suggests being exactly the machine for making knit fabric.Knitting machine can be divided into flatbed knitting machine and circular knitter by the form of needle-bar, and circular knitter can be divided into large-scale circular knitting machine and miniature circular knitting machine by size, i.e. so-called large circle machine and little circular knitting machine.Simultaneously along with the progress of technology, knitting machine being mounted with corresponding full-jacquard mechanism, it is achieved fabric is carried out jacquard weave by knitting machine in braiding process simultaneously, the knitting needle circular knitting machine with jacquard weave function is called jacquard circle knitting machine.Jacquard circle knitting machine is not fee from yarn adhesive dust in knitting machine weaving process, and dust accretions can cause the abrasion of knitting cam in knitting needle or braiding adjustment seat on knitting machine in the braiding adjustment seat of dials or bottom cylinder, thus affecting the weaving quality of fabric, it is therefore necessary to improved.
Summary of the invention:
The purpose of the present invention aims to solve the problem that prior art Problems existing, it is provided that one can reduce dust and enter braiding adjustment seat, reduces the abrasion of knitting cam in braiding adjustment seat, thus improving the computer jacquard with dust guard of weaving textile quality.
nullThe present invention relates to a kind of computer jacquard with dust guard,Including the power transmission shaft being connected with jacquard main shaft by gear,Also include being arranged on the dust-proof mechanism above the braiding adjustment seat of jacquard,Described dust-proof mechanism includes being arranged on the dust-proof frame above described braiding adjustment seat、It is arranged on the dust excluding plate in described dust-proof frame、It is pressed against the Roller for sticking dust on described dust excluding plate、It is fixedly connected on the rotating shaft of described Roller for sticking dust one end and fixed cover is located at the driven wheel of differential of described rotating shaft one end,The medial wall of described dust excluding plate and dust-proof frame fits,It is fixedly connected with back-moving spring between one sidewall and the one side medial wall of dust-proof frame of dust excluding plate,The upper surface of dust excluding plate forms the tooth-strip part of strip,Described Roller for sticking dust forms the gear ring portion of annular,Described gear ring portion is meshed with described tooth-strip part,The dust-proof frame of Roller for sticking dust side forms groove,One sidewall of described dust excluding plate may pass through described groove,Described rotating shaft is fixed on jacquard by bearing;
Described power transmission shaft is positioned at the side of described driven wheel of differential, the lateral wall of power transmission shaft forms external splines, power transmission shaft is arranged with the drive bevel gear corresponding with driven wheel of differential, the middle part of described drive bevel gear has through hole, the inwall of described through hole has the internal spline coordinated with described external splines, power transmission shaft be arranged over piston rod lift cylinder straight down, the piston-rod lower end of described lift cylinder is fixedly connected with lifter plate, the lower end of described lifter plate is hinged with rotation bar, the sleeve hole coordinated with power transmission shaft is formed in the middle part of the bottom surface of described rotation bar, described sleeve hole sleeve is in the upper end of power transmission shaft, the bottom rotating bar is fixed on the upper surface of drive bevel gear.
By technique scheme; the present invention is in use; computer jacquard works; braiding adjustment seat is carried out proofing dust and protecting by the dust-proof mechanism of the top of its braiding adjustment seat; specifically; the dust-proof frame of dust-proof mechanism and dust excluding plate are in the top of braiding adjustment seat, are stopped by the dust originally dropped in braiding adjustment seat, and dust is piled up on dust excluding plate.Power transmission shaft drives drive bevel gear to rotate simultaneously, when the dust accretions on dust excluding plate to a certain extent time, lift cylinder starts, drive and lifter plate moves, lifter plate drives and moves on rotation bar thereon, rotate bar drive to be fixed in the drive bevel gear of its lower end and move, until drive bevel gear is meshed with driven wheel of differential.Drive bevel gear is located on power transmission shaft by the engagement sleeves of the internal spline in its through hole with the external splines on power transmission shaft, so that along with power transmission shaft rotates together the while that drive bevel gear being in the process of upper shifting.When drive bevel gear engages with driven wheel of differential, drive bevel gear drives driven wheel of differential to rotate together, driven wheel of differential is rotated axle and rotates, rotating shaft drives Roller for sticking dust to rotate, gear ring portion on Roller for sticking dust drives the tooth-strip part on dust excluding plate towards a side shifting of dust-proof frame, and the side of dust excluding plate is moved outside dust-proof frame through the groove on dust-proof frame, and back-moving spring is stretched, Roller for sticking dust is in the process rotated, and the dust that dust excluding plate is piled up is adhered to by it.After the dust piled up on dust excluding plate is adhered to completely by Roller for sticking dust, the piston rod of lift cylinder stretches, lifter plate, rotation bar and drive bevel gear is driven to move down, so that drive bevel gear departs from driven wheel of differential again, meanwhile, dust excluding plate recovers to set back under the effect of elastic force at back-moving spring, again fits with the medial wall of dust-proof frame.Afterwards, when the dust on dust excluding plate is piled up again, repeat above step, dust stratification in the braiding adjustment seat of computer jacquard can be avoided to the full extent, improve weaving quality.
By such scheme, the computer jacquard function with dust guard of the present invention reduces dust and enters braiding adjustment seat, reduces the abrasion of knitting cam in braiding adjustment seat, thus improving weaving textile quality.
