Description
Technical field
The invention belongs to technical field of textile machine, and in particular to a kind of shuttleless loom batches cloth-pressing device.
Background technique
Shuttleless loom above-mentioned includes rapier loom, air-jet loom, water-jet loom and gripper shuttle loom, etc., volume above-mentioned
The function of pressure cloth apparatus is that the fabric woven by shuttleless loom is drawn fell, is batched for cloth-winding mechanism, while batching compress
Device also has the booster action to pick count control.
As is known in the industry, shuttleless loom Woven fabric is carried out on the basis of certain level warp tension, is being batched
During fabric is drawn fell by cloth-pressing device, other than work beam actively batches, depended on pressure roller (commonly referred to as " compress is also needed
It is roller ", the same below) and work beam cooperation make the fabric between cloth pressing roller and work beam generate frictional force to fabric surface into
Row control avoids fabric from generating sliding or travelling situation, that is to say, that need that fabric is pressed on work beam table by cloth pressing roller
Face is just able to fabric drawing fell.Warp tension is applied on work beam and cloth pressing roller via the fabric being just made into.
Applying pressure at the both ends of cloth pressing roller using spring pressurization mechanism and cloth pressing roller is made to be adjacent to work beam is current industry
The technological means passed through, but due to certain heavily fabrics (i.e. big grammes per square metre fabric), high-density fabric and smooth fabric etc., because
Warp tension is big, fabric and work beam skin-friction force are small, spring pressurization mechanism pressure is insufficient, Looms pressure roller rigid not
Factors such as foot, thus fabric can not be reliable and be equably pressed on and batch roller surface by cloth pressing roller, especially in the middle part of cloth pressing roller because
Limited rigidity and be deformed, fabric can not be pushed down.Also, since the installation space that shuttleless loom batches cloth-pressing device is limited, because
And can not and it not allow to improve the rigidity of cloth pressing roller by without limit to increase the diameter of cloth pressing roller yet.Cloth pressing roller
The reason of middle part of length direction generates upward bending deformation (generating arch) relative to work beam is: because cloth pressing roller is opposite
It is tediously long, especially for breadth compared with as large as reaching three meters or even broader shuttleless loom, because in the middle part of cloth pressing roller away from both ends spindle nose
Fixed positional distance is longer, and suffered tension force effect torque shows as maximum, is greater than manufacture pressure when tension force effect torque reaches
When the material (metal material) of power roller is difficult to the bending resistance degree or beaming resistance limit degree resisted, the middle part of cloth pressing roller is because to arch
It rises and forms gap between work beam.Therefore how to ensure cloth pressing roller the problem of its length direction is equably close to work beam
Industry is suffered from for a long time, and it is expected effectively to be solved.
The technical information for batching cloth-pressing device about shuttleless loom can be seen in disclosed Chinese patent literature, it is typical

Interior pressure roll, the both ends of interior pressure roll lean out the both ends of cavity, that is, lean out the both ends of pressure roll, the both ends of pressure roll are respectively constituted
For cylindrical end axis, and olive shape is shaped in the middle part of pressure roll, the bearing inner race cooperation of cylindrical end axis and bearing, and bearing
It is fixed in pressure roll support plate.Furthermore at least two bearings are installed on interior pressure roll, for details, reference can be made to saying for the patent
The the 0023rd and 0027 section of bright book.
Above-mentioned CN201627042U can objectively be embodied in three aspects of the 0014th to 0016 section of its specification conclusion
Technical effect, but there are still following shortcoming: first, the pressure roll (i.e. " cloth pressing roller ") instructed due to the patent is once being installed to
The pressure of the application for the work beam being disposed below cannot be changed according to fabric after between a pair of of wallboard, pressure is made into adaptability
Adjustment, such as the smooth fabric etc. pair of heavily fabric (big grammes per square metre fabric), high-density fabric, broad fabrics and silk etc
Tensile requirements have differences；For another example fabric web cloth width is different, also accordingly has differences to the pressure of pressure roll, therefore, with
The fabric of constant pressure roll Stress coping variation and the breadth width of reply variation apply identical pressure and have centainly
Blindness, as a result, being difficult to obtain the desired tensile requirements to different fabrics；Second, due to needing to be equipped with one for pressure roll
To the pressure roll support plate as lining, and need to be equipped with a pair of interior pressure roll support plate as Side fascia for interior pressure roll
(a pair of of pressure roll support plate is fixed with the opposite side of pressure roll support plate in a pair respectively), thus it is not easy to manufacture and dress
Match；Third, due to being designed to olive shape in the middle part of the length direction by pressure roll, thus the difficulty of processing of pressure roll is big and add
Material wastage rate during work is high, is unfavorable for saving resource.
For above-mentioned prior art, it is necessary to be improved, the applicant has made beneficial design thus, forms following
