Description

Technical Field

[0001] This utility model relates to the field of rapier loom technology, and in particular to a separate independent pressure mechanism for a rapier loom. Background Technology

[0002] Rapier looms are currently the most widely used shuttleless looms. In addition to the characteristics of high speed, high automation and high efficiency of shuttleless looms, their active weft insertion method has strong adaptability to various types of yarns.

[0003] A search revealed Chinese Patent Publication No. CN208328261U, which discloses a rapier belt pressurizing device for a rapier loom. This utility model, through the addition of a bracket, locking casters, connecting horizontal plates, a lower pressure plate, a circular sliding shaft, a vertical sliding plate, a sliding cylinder, a buffer spring assembly, a rotating seat one, a rotating rod, a rotating seat two, a contact roller, a vertical positioning column, a fixed cylinder, a clamping rod, a limiting plate, and a return spring, as well as the cooperation between the various components, ensures that the woven thread remains compact during use, thereby guaranteeing the normal operation of the rapier loom. At the same time, the height of the contact roller can be adjusted, and the slack can also be adjusted accordingly. It has a wide range of applications and is easy to operate, meeting people's needs in production and daily life.

[0004] While the device can adjust the pressure of the textile thread through the contact roller, when a greater pressure is needed, the operator still has to manually adjust the height of the vertical positioning frame to adjust the pressure of the contact roller on the textile thread. This is not only very troublesome, but the height of the vertical positioning frame cannot be infinitely adjusted, which results in a limited range of pressure exerted by the contact roller on the textile thread. To address this issue, a separate independent pressurization mechanism for rapier looms is proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 One embodiment of this utility model is a detachable independent pressure mechanism for a rapier loom, comprising a body 1, wherein a pressure component 2 and a positioning component 3 are disposed inside the body 1.

[0033] Reference Figures 1-3, the pressing component 2 includes a cross bar 21. Sliders 22 are fixedly installed at both ends of the cross bar 21. The sliders 22 are slidably connected to the inner wall of the machine body 1. The sliders 22 can provide guidance for the cross bar 21 to enable the cross bar 21 to move smoothly up and down. A limiting frame 23 is fixedly installed on the outer wall of the cross bar 21. The shape of the limiting frame 23 is a "C" - shaped structure. A pressing roller 24 is sleeved on the outer wall of the cross bar 21. By using the cross bar 21 in cooperation with the pressing roller 24, different pressures can be applied to textile threads of different materials. There are two groups of cross bars 21. The two groups of cross bars 21 are mirror - set inside the machine body 1 with the rotating shaft 27 as the central axis, and pressing rollers 24 are sleeved on the outside of both groups of cross bars 21. The two ends of the pressing roller 24 are in contact with the inner wall of the limiting frame 23. The limiting frame 23 can axially limit the pressing roller 24. The pressing roller 24 is a hollow tubular structure with openings at both ends. A spring 25 is fixedly installed on the outer wall of the cross bar 21. The end of the spring 25 away from the cross bar 21 is in contact with the inner wall of the pressing roller 24. Due to the elasticity of the spring 25, the pressure applied by the pressing roller 24 to the textile thread is more flexible. It can not only prevent the wire from breaking due to excessive tension, but also keep the pressing roller 24 in contact with the textile thread all the time when the tension of the textile thread suddenly decreases. Furthermore, it can make the textile thread maintain a certain tension during the fabric - making process. A motor 26 is fixedly installed on the right side of the machine body 1. The output end of the motor 26 is fixedly installed with a rotating shaft 27. The end of the rotating shaft 27 away from the motor 26 penetrates the machine body 1 and is fixedly installed with a turntable 28. The penetrating part of the rotating shaft 27 and the machine body 1 is rotatably connected. Starting the motor 26 drives the rotating shaft 27 to rotate, making the rotating shaft 27 drive the turntable 28 to rotate. A connecting rod 29 is hinged on the outer wall of the turntable 28. The end of the connecting rod 29 away from the turntable 28 is hinged on the outer wall of the slider 22 at the right end of the cross bar 21. When the turntable 28 rotates and cooperates with the connecting rod 29, it can drive the slider 22 to slide on the inner wall of the machine body 1.

[0034] Referring to Figures 2-3 , the positioning component 3 includes that one end of a bidirectional screw rod 31 is rotatably connected to the inner wall of the limiting frame 23. The other end of the bidirectional screw rod 31 penetrates the limiting frame 23 and is fixedly installed with a hand wheel 32. The penetrating part of the bidirectional screw rod 31 and the limiting frame 23 is rotatably connected. By turning the hand wheel 32, it is convenient to rotate the bidirectional screw rod 31. A guiding block 33 is slidably connected to the inner wall of the limiting frame 23. The guiding block 33 is threadedly connected to the bidirectional screw rod 31. By rotating the bidirectional screw rod 31, the two groups of guiding blocks 33 threadedly connected to it can slide synchronously in the inner wall of the limiting frame 23 in opposite directions. A guiding disk 34 is sleeved on the outer wall of the pressing roller 24. A groove 35 is opened at the bottom of the guiding block 33. The outer walls at both ends of the guiding disk 34 are in contact with the inner wall of the groove 35. The groove 35 can axially limit the guiding disk 34, enabling the guiding disk 34 to move synchronously with the guiding block 33.

[0035] Working principle: In use, the textile thread passes through the bottom of the pressure roller 24 below the turntable 28, and then passes through the top of the pressure roller 24 above the turntable 28 and is guided into the interior of the machine body 1, so that the textile thread is wound in an "S" shape on the two sets of pressure rollers 24. At this time, the motor 26 is started to drive the rotating shaft 27 to rotate, which in turn drives the turntable 28 to rotate. As the turntable 28 rotates, it pushes the connecting rod 29, which pushes the slider 22 at the right end of the crossbar 21. This causes the sliders 22 at both ends of the two sets of crossbars 21 to slide synchronously in opposite directions on the inner wall of the machine body 1. When the two sets of sliders 22 move away from each other, the two... As the crossbars 21 move further apart, the pressure rollers 24 fitted around the crossbars 21 apply pressure to the textile thread. Simultaneously, the directional force exerted by the textile thread on the pressure rollers 24 causes the pressure rollers 24 to compress the springs 25 on the outer wall of the crossbars 21. Under the pressure of the pressure rollers 24, the textile thread can be kept neatly wound around the outside of the two sets of pressure rollers 24. When the two sets of sliders 22 approach each other, the two sets of crossbars 21 also approach each other. At this time, the pressure applied to the textile thread by the pressure rollers 24 fitted around the crossbars 21 gradually weakens, and the pressure can be freely adjusted according to the different materials of the textile thread.

[0036] When the tension of the spinning thread suddenly increases during the weaving process, the reverse force exerted by the spinning thread on the pressure roller 24 will cause it to compress the outer wall spring 25 of the crossbar 21. The spring 25 can absorb the tension of the spinning thread, thereby preventing the spinning thread from breaking and improving spinning efficiency. When the tension of the spinning thread suddenly decreases during the weaving process, the spring 25 will push the pressure roller 24 to keep it in contact with the outer wall of the spinning thread, thereby maintaining the tension of the spinning thread and allowing the spinning thread to enter the machine body 1 in a neat state for weaving, thus improving the weaving effect.

[0037] Rotating the bidirectional lead screw 31 via the handwheel 32 causes the two sets of guide blocks 33, which are threadedly connected to it, to slide synchronously in opposite directions on the inner wall of the limiting frame 23. While sliding, the guide blocks 33, under the limiting action of the groove 35, push the guide disc 34 to move synchronously on the outer wall of the pressure roller 24. This allows adjustment of the distance between the two sets of guide discs 34. The guide disc 34 can be adjusted to a suitable position according to the width of the textile thread laid on the pressure roller 24. The guide disc 34 guides the textile thread laid on the pressure roller 24, keeping the textile thread neat and tidy for weaving, thus further improving the weaving effect.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
