[0014] Figure 1 This is a schematic diagram of an application of a warp tension adjustment device for a weaving beam edge according to the present invention;
[0015] Figure 2 The utility model is a structural schematic diagram of a warp tension adjustment device at the edge of a loom beam. DETAILED DESCRIPTION
[0016] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.
[0017] like Figures 1 to 2As shown, a warp tension adjustment device for the edge of the weaving shaft in this embodiment is provided on the warp stop frame 100 of the loom, and the adjustment device includes an upper adjusting body 10 and a lower adjusting body 20 which are arranged in the same vertical plane and are divided into upper and lower parts. The upper adjusting body 10 and the lower adjusting body 20 are respectively movably connected to the warp stop frame 100 and both have a motion trajectory moving in the vertical direction. The lower adjusting body 20 is used to support the lower surface of the lower warp yarn 42, and the upper adjusting body 10 is used to be pressed on the upper surface of the upper warp yarn 41.
[0018] This warp tension adjustment device for the weaving beam edge utilizes the warp stop frame 100 of the loom and can be mounted on the frame bar of the warp stop frame. It can be manufactured in various shapes, allowing it to be pressed against the upper warp yarns 41 or supported beneath the lower warp yarns 42. Adjusting the mounting height allows for quick and convenient adjustment of the warp tension at the weaving beam edge. This utility model maintains the original structure of the loom and offers a simple design, easy installation, and low cost.
[0019] Furthermore, the adjustment device has a first state, a second state, and a third state. When the adjustment device is in the first state, the lower adjustment body 20 is supported on the lower surface of the lower warp yarn 42, and the upper adjustment body 10 is spaced apart from the lower adjustment body 20 and the upper warp yarn 41. When the adjustment device is in the second state, the upper adjustment body 10 is pressed against the upper surface of the upper warp yarn 41, and the lower adjustment body 20 is spaced apart from the upper adjustment body 10 and the lower warp yarn 42. When the adjustment device is in the third state, the lower adjustment body 20 is supported on the lower surface of the lower warp yarn 42, and the upper adjustment body 10 is pressed against the upper surface of the upper warp yarn 41, and the upper adjustment body and the lower adjustment body directly form a passage gap for the warp yarn. Through the above three usage states, different states can be selected based on the actual warp tension adjustment needs, and the specific tension can be adjusted by changing the height position of the corresponding adjustment body.
[0020] In actual application, the warp stop frame 100 of the loom has an inlet and an outlet for the warp yarn to pass through, and the lower ends of the inlet and outlet are respectively provided with a rear frame bar 102 and a front frame bar 101, and the two adjusting devices are respectively provided on the rear frame bar 102 and the front frame bar 101 or one adjusting device is provided on the front frame bar 101.
[0021] It can be understood that, as a preferred embodiment, the upper adjusting body 10 includes an upper connector 11 and an upper warp contact body 12 fixedly connected to the upper connector 11, and the lower adjusting body 20 includes a lower connector 21 and a lower warp contact body 22 fixedly connected to the lower connector 21. The upper warp contact body 11 and the lower warp contact body 21 are arranged in the same vertical plane and are arranged in upper and lower parts. The upper connector 11 and the lower connector 21 are respectively connected to the frame bar via a locking assembly 30. The locking assembly 30 is used to lock the relative position of the upper connector 11 and the lower connector 21. In other words, through the above structural arrangement, when the locking assembly 30 is in a loose state, the height of the upper connector 11 and the lower connector 21 can be changed to match the specific warp tension required. When the appropriate tension position is reached, the upper connector 11 and the lower connector 21 are locked by the locking assembly 30, thereby fixing the relative position of the upper warp contact body 12 and the lower warp contact body 22.
[0022] In this embodiment, the upper connecting body 11 and the lower connecting body 21 are both L-shaped plates, and the two L-shaped plates are stacked. The contact edges of the two L-shaped plate stacks are provided with strip holes 50 arranged along the vertical direction, and connecting holes are provided on the frame bars corresponding to the strip holes 50. The locking assembly 30 includes screws and nuts, and the screws are passed through the two strip holes and the connecting holes and are locked and connected via nuts.
[0023] Furthermore, the sides of the L-shaped plates with the strip-shaped holes 50 are arranged parallel to the front surfaces of the frame bars, and the other sides of the two L-shaped plates extend in the direction of the yarn outlet, so that the upper warp contact body 12 and the lower warp contact body 22 are spaced apart from the yarn outlet. This arrangement can achieve the goal of not affecting the original structure of the warp stop frame without affecting its own function.
[0024] Preferably, the upper warp yarn contact body 12 and the lower warp yarn contact body 22 are symmetrically arranged. The upper warp yarn contact body 12 includes a first rod arranged along the width direction of the upper warp yarns, and the first rod is bent upward at an angle at one end away from the upper connecting body. The lower warp yarn contact body 22 includes a second rod arranged along the width direction of the lower warp yarns, and the second rod is bent downward at an angle at one end away from the lower connecting body. Specifically, the upward-angled bending arrangement of one end of the first rod and the downward-angled bending arrangement of the end of the second rod away from the lower connecting body can avoid limiting the warp yarns along the width direction.
[0025] Preferably, there are two adjusting devices, which are respectively arranged on the left and right sides of the front frame bar.
[0026] The utility model also provides an air jet loom, which comprises a warp tension regulating device at the edge of a weaving beam.
[0027] By utilizing the warp stop frame 100 of the loom, the adjustment device is installed on the left and right sides of the front frame 101 of the warp stop frame 100. Of course, depending on actual needs, it can be installed on only one side or both sides. This new device can be manufactured in various shapes, and can be pressed against the upper warp yarns 41 or supported under the lower warp yarns 42. By adjusting the installation height, the warp tension at the edge of the weaving beam can be quickly and conveniently adjusted. This utility model does not change the original structure of the loom, has a simple structure, is easy to install and use, and is low in cost.
[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
