Description
Technical Field
The invention belongs to the technical field of textile machinery, and particularly relates to a winding and cloth pressing device of a shuttleless loom.
Background
The shuttleless loom includes a rapier loom, an air jet loom, a water jet loom, a projectile loom, etc., and the function of the winding and pressing device is to draw the fabric woven by the shuttleless loom out of the fabric opening for winding by the winding mechanism, and the winding and pressing device also has an auxiliary function of controlling the weft density of the fabric.
As known in the art, weaving a fabric by a shuttleless loom is performed on the basis of a certain level of warp tension, and in the process of leading the fabric out of a weaving port by a winding and pressing device, in addition to active winding by a winding roller, a pressure roller (commonly called a "cloth pressing roller", hereinafter the same) is required to cooperate with the winding roller to enable the fabric between the cloth pressing roller and the winding roller to generate friction force so as to control the surface of the fabric, thus avoiding the slipping or swimming situation of the fabric, that is, the fabric needs to be tightly pressed on the surface of the winding roller by the cloth pressing roller so as to be led out of the weaving port. Warp tension is applied over the take-up and pinch rolls via the freshly woven fabric.
The spring pressing mechanism is used for applying pressure on two ends of the cloth pressing roller to enable the cloth pressing roller to be tightly attached to the winding roller, but the cloth pressing roller cannot reliably and uniformly press the cloth on the surface of the winding roller, particularly the middle part of the cloth pressing roller cannot be pressed due to deformation caused by limited rigidity due to the fact that the cloth pressing roller cannot press the cloth because of the factors such as high warp tension, small friction force between the cloth and the surface of the winding roller, insufficient pressure of the spring pressing mechanism, insufficient rigidity of the wide loom pressure roller and the like. Further, since the installation space of the shuttleless loom winding cloth pressing device is limited, it is impossible and also impossible to increase the rigidity of the cloth pressing roller by increasing the diameter of the cloth pressing roller without restriction. The reason why the middle portion of the cloth pressing roller in the length direction generates upward bending deformation (camber generation) with respect to the take-up roller is that: because the cloth pressing roller is relatively lengthy, especially for shuttleless looms with a larger width, such as up to three meters or more, the tension moment exerted by the cloth pressing roller is maximum because the middle part of the cloth pressing roller is longer from the fixed positions of the shaft heads at the two ends, and when the tension moment reaches a bending resistance degree or bending limit degree which is more than the material (metal material) for manufacturing the pressure roller and is difficult to resist, a gap is formed between the middle part of the cloth pressing roller and the winding roller because of upward arch. The problem of ensuring that the pressure cloth roller is uniformly abutted against the take-up roller in the length direction thereof has long been plagued in the industry and is desired to be effectively solved.
Technical information about a reeling and pressing device of a shuttleless loom is seen in the published chinese patent literature, and a typical "novel rapier loom reeling and pressing device" as recommended in CN201627042U is that a pressure roller (referred to as an "outer pressure roller" in patent) is formed into a cavity, the cavity penetrates from one end to the other end of the pressure roller in the length direction, an inner pressure roller is disposed in the cavity, two ends of the inner pressure roller protrude from two ends of the cavity, namely, two ends of the pressure roller protrude from two ends of the pressure roller, the two ends of the pressure roller are respectively formed into cylindrical end shafts, the middle part of the pressure roller is formed into an olive shape, the cylindrical end shafts are matched with bearing inner rings of bearings, and the bearings are fixed in a pressure roller supporting plate. Furthermore, at least two bearings are mounted on the inner pressure roller, see in particular paragraphs 0023 and 0027 of the specification of this patent.
The above CN201627042U can objectively exhibit technical effects in three aspects of the description thereof summarized in paragraphs 0014 to 0016, but the following drawbacks still exist: first, since the pressure roller (i.e., the "cloth roller") taught by this patent, once installed between a pair of wallboard panels, the applied pressure of the take-up roller located therebelow cannot be adapted to the fabric changes, such as heavy fabrics (heavy weight fabrics), high density fabrics, wide fabrics, smooth fabrics such as silk, and the like, having differences in tension requirements; as another example, the widths of the fabric widths are different, and the pressures of the pressure rollers correspondingly differ, so that the pressure rollers can be used for coping with the changed fabrics and coping with the same pressure applied by the changed widths of the fabrics with constant pressure rollers have a certain blindness, and as a result, the expected tension requirements of different fabrics are difficult to obtain; secondly, because the pressure roller is required to be provided with a pair of pressure roller supporting plates serving as inner wallboards, and the pressure roller is required to be provided with a pair of inner pressure roller supporting plates serving as outer wallboards (the pair of pressure roller supporting plates are respectively fixed with the opposite sides of the pair of inner pressure roller supporting plates), the manufacturing and the assembly are inconvenient; thirdly, because the middle part of the pressure roller in the length direction is designed to be olive-shaped, the processing difficulty of the pressure roller is high, the material loss rate in the processing process is high, and the resource saving is not facilitated.
In view of the above prior art, improvements are necessary, for which the applicant has advantageously devised a solution which will be described below and which has proved to be practical by computer simulation deduction tests with security measures.

Please focus on fig. 2 and continue to combine with fig. 1, the preferred, but not absolutely limiting, construction of the torsion bar torsion adjustment mechanism 7 described above is as follows: comprising a worm support mount 71, a worm support mount 72, a worm 73 and a worm wheel 74, the worm support mount 71 being fixed to the top of the left insert plate 1 by means of a worm support mount screw 711, the worm support mount 72 being preferably fixed to the worm support mount 71 in a welded manner, the worm support mount 72 having a worm support chamber 721, the front end of the worm 73 being rotatably supported on the front chamber wall of the worm support chamber 721, the rear end of the worm 73 being rotatably supported on the rear chamber wall of the worm support chamber 721, the middle of the worm 73 being located in the worm support chamber 721 and in driving engagement with the worm wheel 74, and the worm wheel 74 being fixed to the left end of the torsion bar 6.
As shown in fig. 2, the front end of the worm 73 is rotatably supported by the front wall of the worm support chamber 721 via a worm front support bearing 731 and extends forward of the front wall of the worm support chamber 721, and the rear end of the worm 73 is rotatably supported by the rear wall of the worm support chamber 721 via a worm rear support bearing 732.
A torsion bar fixing hole 741 is formed in a center of the worm wheel 74 to extend from the left side to the right side of the worm wheel 74, and the torsion bar fixing hole 741 is fixed to the left end of the torsion bar 6. The shape of the torsion bar fixing hole 741 is required to be adapted to the cross-sectional shape of the torsion bar 6.
Further, as shown in fig. 2, a worm operation handle connector 733 for operating the worm 73 is formed at the front end portion of the worm 73, and the worm operation handle connector 733 is a hexagonal head.
A swivel 613 is preferably rotatably provided on the torsion bar left support seat 61 at a position corresponding to the left end of the torsion bar 6, and the torsion bar left support hole 612 is opened in the swivel 613.
Referring to fig. 3 in combination with fig. 1 and 2, a fabric 8 woven by a shuttleless loom is shown in fig. 3, the fabric 8 being led out of the fabric opening of the shuttleless loom in a state between the passing cloth pressing roller 3 and the take-up roller 4 and taken up by a take-up mechanism (not shown in the drawings). When the pressure of the cloth pressing roller 3 is to be adjusted, the on-line operator or the clamp operator aligns the above-mentioned worm operation handle connector 733 through a hardware tool such as an allen wrench, so that the hardware tool and the worm operation handle connector 733 establish a temporary connection relationship and the worm 73 is operated through the hardware tool, so that the worm 73 rotates, the worm wheel 74 is driven by the worm 73, and since the worm wheel 74 is fixed with the left end of the torsion bar 6 through the torsion bar fixing hole 741 thereof, when the worm 73 drives the worm wheel 74 to rotate, the torsion bar 6 is twisted, the torsion force generated by the torsion bar 6 is transmitted to the mandrel 5 through the torsion bar caulking groove 51, and then the mandrel 5 is simultaneously transmitted to the mandrel left and right bearings 52, 53 and the mandrel intermediate bearing 54, and the torsion force generated by the torsion bar is converted into a pressure to be applied (i.e., applied) on each section of the cloth pressing roller 3, so that the cloth pressing roller 3 is uniformly pressed on the surface of the winding shaft 4, thereby achieving a uniform pressing effect, even if the fabric is pressed in the middle of the width of the cloth pressing roller 3.
Since shuttleless looms vary in the tension required for fabrics 8 of different textures (i.e., different raw materials), different grammages and different widths, heavy fabrics, high density fabrics and wide fabrics such as those mentioned above typically require a large and uniform pressure from the cloth roller 3, which can be controlled by the degree of clockwise or counterclockwise operation of the worm 73. As another example, facing smooth fabrics like silk fabrics, also mentioned above, require good compression by the cloth roller 3 but not so much too much compression that the fabric would wrinkle or even damage the silk fabric, and thus the compression force of the cloth roller 3 against the silk fabric needs to be adapted relative to the thick, high-density fabric and wide fabric mentioned before, which is also achieved by a reasonable control of the degree of operation of the worm 73. It should be noted that: facing the silk fabric, a rubber layer having an anti-slip texture is generally coated on the surface of the cloth pressing roller 3.
In summary, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the task of the invention, and faithfully honors the technical effects carried by the applicant in the technical effect column above.
