Description
Technical field
This utility model relates to technical field of textile machine, and specifically one is applied to middle framing loom
Pneumatic scissors and Tucked-in selvage apparatus.
Background technology
The shears of loom and fold into the block assembly problem that is primarily present following several respects in the market:
First, it is to use mechanical mechanism or electronic structure two schemes mostly, both schemes comprise
Mechanism part is many, and structure is complicated, and is not easy to assembling and debugging.
3rd, current Tucked-in selvage apparatus and scissors apparatus use split-type structural mostly, i.e. completely solely
Two kinds of vertical devices are separately mounted on loom, remove the cooperation position debugged therebetween the most again, this
Scenario-frame is complicated, and parts kind is many, and cost is high, installation and debugging difficulty.
3rd, for middle framing loom, when needs change loom split, after needing according to adjusting
Split determine the length of the series parts such as two ends reed, slay and ladder type ferrum, adjust the most again in the middle of
Scissors apparatus and Tucked-in selvage apparatus.And due between reed and shears and the Tucked-in selvage apparatus of Tradition Looms
It is movement relation in relative rotation, after shears and Tucked-in selvage apparatus are adjusted, back and forth transports at reed
During Dong, will certainly interfere with the shears adjusted and Tucked-in selvage apparatus, in order to avoid this
The generation of phenomenon, it is therefore necessary to reed to be blocked, make to keep between reed and Tucked-in selvage apparatus certain away from
From, the most often change a cloth cover kind and be accomplished by a set of corresponding reed model and support the use, not only increase
Oil (gas) filling device cost, and the process that adjusts also is the most loaded down with trivial details, has had a strong impact on production efficiency, and has given client
Bring inconvenience.

Sheet 1292 rotates together.
As shown in Figure 4 and Figure 6, the first described invagination block 13 is arranged at described first scissors base 11
Inner side, and be connected with source of the gas by gas circuit, and the direction of arrow shown in Fig. 4 is air-flow emission direction,
Making the inside lateral buckling of the end of a thread after cutting off by the way of air-flow brushes, described first folds into the gas circuit of block 13
Use Patent No. 201510459863.X (patent name is the pneumatic Tucked-in selvage apparatus of loom) middle public affairs
The gas circuit opened, does not repeats them here.Further, in order to convenient adjustment first folds into block 13 and cuts
Distance between knife assembly 129, and then the length folding into yarn is adjusted, as shown in Figure 4, institute
Pad 4 it is provided with between the first invagination block 13 and the first scissors base 11 stated, thus can be by adjusting
Pad 5 adjusts the distance between the first invagination block 13 and cutting assemblies 129.
During work, the air inlet of gas circuit A, gas circuit B gives vent to anger → the first plunger moves right → and shift fork turns counterclockwise
Dynamic → shears moving plate relative to shears still rotate counterclockwise → shears opens → weft yarn is through shears mouth → gas
Road B air inlet, gas circuit A gives vent to anger → the second plunger is moved to the left → and shift fork rotates clockwise → shears moving plate phase
For shears still rotate clockwise → shears close → cut off weft yarn → the first fold into block gas circuit work,
Complete the work of weft yarn tuck-in selvage.
Further, during due to work, the first plunger 122 and the second plunger 123 are relative to the first shears
Seat 11 slides frequently, is equivalent to single-acting cylinder, therefore adds man-hour, described the first plunger 122,
The outer surface of the second plunger 123, and the first scissors base 11 and the first plunger 122 and the second plunger 123
The first hole matched and the requirement on machining accuracy of the inner surface in the second hole are the highest, and the first scissors base 11
Irregularly shaped bring certain difficulty to processing, to this end, the first described plunger 122 and the first hole
Between be provided with first sleeve 124, be provided with the second sleeve pipe between described the second plunger 123 and the second hole
125.Install for convenience, as it is shown in figure 1, the second described sleeve pipe 125 is the tubular structure of hollow,
Described first sleeve 124 is provided with the tubular structure of annular boss for one end, and the first described hole is logical
Hole, the position that the front side of described first scissors base 11 is corresponding with the first hole is provided with the first scissors base end cap
It is provided with the passage for connecting the first hole and gas circuit A in 14, and the first described scissors base end cap 14.
In order to improve sealing, between described first sleeve 124 and the first scissors base end cap 14, and second
It is provided with sealing ring 126 between sleeve pipe 125 and the first scissors base 11.The most when mounted, first will
One sealing ring 126 is arranged at the rear end in the second hole, then by the second sleeve pipe 125 from the front side in the first hole
Insert, be inserted in the second hole behind the first hole, and be resisted against the sealing ring 126 being arranged in the second hole
On, then by same method, the second plunger 123 is inserted in the second sleeve pipe 125.Then by first
Sleeve pipe 124 inserts from the front side in the first hole, until be arranged at the annular boss of first sleeve 124 one end with
First scissors base 11 is adjacent to, and here this annular boss plays the effect of location, then by the first plunger 122
It is inserted in first sleeve 125 from the front side of first sleeve 124, installs sealing ring 126 the most successively
With the first scissors base end cap 14.
As it is shown in fig. 7, described temporary location is similar to described end unit structure, difference is institute
The temporary location stated includes that the second scissors base, the side of described second scissors base are provided with the second scissors module,
And the second described scissors module is identical with the first described scissors module structure.Described second scissors base
