Description
Technical field
The invention belongs to weaving technology fields, and in particular to a kind of pair of weft heating scissors for a rapier loom device.
Background technology
Filling cutter device custom above-mentioned is known as " latitude cuts device ", is based on this, filling cutter is known as " latitude is cut ".Arrow shaft
Loom is the bar using the sword shape moved back and forth（That is arrow shaft）It pitches into or clamps weft yarn and weft yarn is introduced to the shuttleless loom of fell.
Since rapier loom is shown as latitude outside machine, for weft yarn by the positive control of sword head, wefting insertion quality is high, and since rapier loom is weaved
Speed is fast, high degree of automation, positive filling insertion way there is extremely strong adaptability, the wefting insertion that can meet all kinds of yarns to want kind
It asks, it also has the clear superiority that other looms can not match in excellence or beauty therewith in terms of polychrome weaving in addition, such as can weave up to ten
The fabric of several colors or even more chintzing, thus whether pass by or at present so one period is still that industry is in one's favour from now on
Textile machine.
As is known in the industry, rapier loom is equipped with filling cutter device above-mentioned, the mechanism of action of the filling cutter device
It is in weft-sending sword head（That is " wefting insertion sword head "）By weft yarn quick shearing after clamping weft yarn, and require the time of cutting weft yarn very
Accurately.Pair of weft heating scissors for a rapier loom device in prior art is make upper and lower two pieces of blades in the form of Mechanical Driven past
Weft yarn is cut in multiple movement, and it is opposite that the filling cutter device of Mechanical Driven only adapts to yarn cutting material, count of yarn difference
Smaller weft yarn and complexity is adjusted, in particular, if the big weft yarn of yarn material, count of yarn difference weaved simultaneously,
It needs to set the shear time of different weft yarns, filling cutter is generally driven using servo motor.Weft yarn is driven using servo motor
" a kind of rapier loom electric weft shear mechanism " that the typical example of scissors such as Chinese patent CN204982245U recommends and
" the loom swinging weft-yarn shearing device ", etc. that CN207619605U is provided is not limited to the patent enumerated due to using
Servo motor, thus the cost is relatively high and it is very complicated to control.
Using solenoid actuated filling cutter in addition to exist with using servo motor aforementioned shortcoming other than there is also electric signals
It is easy to be interfered and influences drawback, the typical example such as CN202809134U of solenoid actuated filling cutter（A kind of electric rotating
Magnetic-type filling cutter device）And CN103757811A（A kind of electronic weft yarn shearing-off device）.

Applicant combines the process of Fig. 1 and Fig. 2 summary present invention cutting weft yarns, when the structure of cutting blade driving mechanism 2
The pneumatic control electromagnetism valve events for controlling the work of cylinder 22 of system, ambient pressure air is such as by air compressor or similar
Air pipe interface 222 of the pressure air that compressed air source unit provides from pipeline 8 from cylinder 22 enters cylinder 22, and cylinder block 221 is overcoming
It is shifted up under the reaction force of driving spring 23, i.e., cylinder block 221 drives cylinder block bulb to the cylinder body intrinsic displacement of cylinder 22
Connector 2211 moves upwards, and driving spring 23 at this time compresses and is in energy storage state.Since the left end of connecting rod 24 passes through ball
Head pin 2411 is connect with the bulb pin hole 22112 of connecting rod connecting ball head 22111, right end by moving knife bobbin connecting rod attachment screw 46 and
Moving knife bobbin 41 connects, thus drives the left end of connecting rod 24 also to transport upwards when cylinder block bulb connector 2211 moves upwards
It is dynamic, to drive moving knife bobbin 41 to turn round an angle clockwise by the right end of connecting rod 24, meanwhile, cutting blade is with moving knife
Piece fixes disk 45 and also accordingly turns round an angle, that is, cutting blade 5 is made to lift, and cutting blade 5 is formed between the two with fixed blade 6
Scissors mouth forms share zone, allow weft yarn to enter the share zone between dynamic and static blade 5,6 at this time, when pneumatic control electricity
Task, the compressed air discharge being previously entered in cylinder 22 will at this time under the reply force effect of driving spring 23 again for magnet valve
221 downlink of cylinder block, by aforementioned opposite action process from cutting blade 5 with the fixed blade 6 under will be located at share zone
Interior weft yarn is cut.
In conclusion technical solution provided by the invention compensates for the shortcoming in prior art, invention has been favorably accomplished
Task has faithfully fulfilled the technique effect that applicant refers in technical effect column above.
