Description

The tension detecting device of itemize warping sizing machine

Technical field

The utility model relates to the warp sizing machine in the textile machine, is meant a kind of tension detecting device of itemize warping sizing machine.

Background technology

The warping of single-yarn textile and starching, the operational path of batch warping commonly used and tape sizing, this mode adapts to requirements of mass production, for look is knitted industry, in order to adapt to the production requirement of small lot and many kinds, have to adopt the mode of single end sizing and section warping, but this mode of production causes shortcomings such as sizing quality difference and kind limitation be big, in order to adapt to small lot, many kinds and special quality production requirement, from the eighties in last century, China's textile industry is carried out the development of itemize warping sizing machine, this machine can be incorporated in section warping and starching on the machine and finish, it is wide to have varietal adaptation, and sizing quality is good, advantages such as the little and trial-production new varieties of production lot are convenient.But this equipment requires very high to tension force automatic guidance and synchrodrive, if cooperate badly, can cause overtension, and the high and slurry of end breakage rate yet there are no relevant report, the domestic same category of device of also not seeing abroad at present through problem such as of poor quality.

Summary of the invention

In order to solve the not even automatically controlled difficult problem of Tension Control in the itemize warping sizing machine synchronous drive mechanism, the utility model provides a kind of tension detecting device of synchronous drive mechanism of electromechanical integration.

The technical scheme that the utility model proposed is: identical loop component two covers that the tension detecting device of synchronous drive mechanism is made up of last lower sprocket and driving chain, be contained in respectively the itemize warping sizing machine before drag on the left and right sides frame between pick-up roll and the preceding lease reed.Jockey pulley and axle bed are contained on the Left Drive chain of lower sprocket midway location, tension weight is contained on the right driving chain, the gear that a gear and compensator are housed at the upper sprocket wheel axle head of frame one side is meshed, and compensator is made up of rotary variable resistance and coaxial bonded assembly gear.When the itemize warping sizing machine is worked, warp tension change for a certain reason, make jockey pulley produce upper and lower displacement, by driving chain, sprocket wheel and gear mesh effect, make rotating potentiometer rotation in the compensator, thereby cause the variation of resistance value, make the setting signal in incoming signal and the electrical equipment control reed produce stack relatively, send instruction and carry out speed governing, make warp tension keep original state, reach synchronous requirement.

Advantage of the present utility model (being effect) is: after adopting this tension detecting device, the synchrodrive problem of itemize warping sizing machine has obtained fine solution, machine operation is steady, yarn tension can be regulated according to technological requirement, realized the operation of small tension receiving coil and permanent tension force, sizing quality is good, can adapt to specific (special) requirements such as height props up, high density fabric, can adapt to the requirement of present domestic small batch production and new varieties.

Description of drawings Fig. 1 is an itemize warping sizing machine structural representation.Fig. 2 is a lifting mode tension detecting device scheme drawing.Fig. 3 is an oscillating type tension detecting device scheme drawing.Label declaration is through axle in the accompanying drawing--1 stock tank------9 jockey pulleys--3 back lease reeds--10 compensators--4 framves--on 11 cured--5 lower sprockets----6 driving chains--13 drying cylinders--7 weights--14 upper sprocket wheel--15 swing arm--16 that drags pick-up roll before 12 of executing pick-up roll after 2 of lease reed before 8

The specific embodiment

Embodiment 1

Fig. 1 is the structural representation that the Shanghai look is knitted the itemize warping sizing machine of Institute Of Science And Technology development, dressed warp moves back from bobbin bank 11 and separates among the figure, through after lease reed 10 and after drag pick-up roll 9, enter stock tank 8 and carry out starching, warp thread after the starching is through drying cylinder 7 oven dry, after before dragging on the pick-up roll 6 cured 5 and preceding lease reed 2, be involved on axle 1 again, finish through axle starching process.Present embodiment provides a kind of lifting mode tension detecting device, see shown in Figure 2, it is by upper sprocket wheel 15, and lower sprocket 12 and driving chain 13 are formed two total identical covers of a loop component, is installed in respectively on the left and right sides frame of dragging before the itemize slurry combination machine between pick-up roll 6 and the preceding lease reed 2.On the right chain of last lower sprocket midway location, bearing seat and jockey pulley 3 are housed, tension weight 14 is housed on the Left Drive chain, and when making operating dressed warp, jockey pulley 3 and weight position is positioned at about the centre through jockey pulley 3.Upper sprocket wheel 15 axle heads in frame one side are equipped with a gear, with the gear mesh on the CYN-1 type compensator 4, compensator 4 is formed existing CYN-1 type by engaging gear and the rotary variable resistance of coaxial bonded assembly thereof and is selected for use the WX72-1 molded lines around resistance, a cover tension detecting device that forms like this, when dressed warp tension force changes, jockey pulley 3 can be moved up and down, through driving chain, sprocket wheel, the engaging gear effect, make the resistance of WX72-1 resistance produce change, make the setting signal in incoming signal and the control reed produce stack relatively, send instruction and carry out speed governing, make the warp tension of starching keep constant, reach the synchrodrive requirement.

Embodiment 2

See shown in Figure 3, this is a kind of oscillating type tension detecting device, the same with last example, form a loop component by upper sprocket wheel 15, lower sprocket 12 and driving chain 13 and have two covers, be contained in respectively the itemize warping sizing machine before drag on the left and right sides frame between pick-up roll 6 and the preceding lease reed 2, respectively adorn a swing arm 16 on 12 cores of two lower sprockets of left and right sides frame, bearing seat and jockey pulley 3 are contained in the left end of swing arm 16, and tension weight 14 is mounted on swing arm 16 right-hand members.The gear that is equipped with on a gear and the CYN-1 type compensator 4 at upper sprocket wheel 15 axle heads of frame one side is meshed, and compensator is linked to each other by engaging gear and coaxial bonded assembly WX72-1 resistance thereof.Such tension detecting device, when warp tension changes, making jockey pulley 3 is that fulcrum is rotation with 12 cores of lower sprocket, through driving chain, sprocket wheel, engaging gear effect, variable resistance is changed, make the setting signal in incoming signal and the control reed produce stack relatively, send instruction and carry out speed governing, thereby keep warp tension constant.

The itemize warping sizing machine be provided with cured 5 o'clock, then the tension detecting device that provides of the utility model can load onto cured and before execute between the pick-up roll.
