Description

Technical Field

[0001] This utility model relates to the field of circular loom technology, and in particular to a lifting guide wire structure for a circular loom. Background Technology

[0002] In the textile industry, circular looms are key equipment for producing various cylindrical fabrics such as woven bags and geotextiles. As the market demands for fabric quality, production efficiency, and diversified product specifications continue to increase, the technology related to circular looms has also been continuously developing and improving.

[0003] In the current use of circular looms, the yarn on the yarn reel usually needs to be passed through the yarn guide frame into the circular loom for weaving into fabric. However, the height of a typical circular loom is quite high, and the traditional guide frames used in circular looms are often very high. When hanging the yarn on the guide frame, it is usually necessary to climb with the help of external objects to hang the yarn smoothly. This method of hanging the yarn at a height has low work efficiency and is prone to falls during the operation, which can cause production safety accidents and is not in line with the principle of safe production of enterprises. Therefore, a lifting guide frame for circular looms is proposed.

[0004] Existing patent (publication number: CN221094436U) discloses a lifting guide frame for a circular loom, belonging to the field of textile equipment technology. This lifting guide frame for a circular loom includes a yarn frame and a circular loom. A yarn wheel is installed on the yarn frame, and yarn on the yarn wheel enters the circular loom for weaving. It also includes a guide rail, a guide frame, and a lifting assembly. The output end of the lifting assembly is fixedly connected to the outer wall of the guide rail, driving the guide rail to move up and down. The guide frame is installed inside the guide rail, and the yarn on the yarn wheel passes through the guide frame into the circular loom. This invention uses a guide frame to suspend the yarn for guiding, and the guide rail facilitates position adjustment of the guide frame. Furthermore, the lifting assembly allows the guide rail to move up and down, lowering the height of the guide rail when suspending the yarn, making it easier for operators to suspend the yarn without having to climb, thus improving work efficiency.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, existing hand-operated small circular looms lack structures for raising and lowering the yarn guides and pressing the yarn. As a result, the yarn can only maintain a fixed feed height and angle during the process of being transported to the weaving area, and the yarn height cannot be adjusted. Consequently, the yarn tension will change significantly, thus affecting the weaving quality of the fabric.

[0006] Therefore, a lifting guide wire structure for circular looms is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a lifting guide structure for circular looms, which solves the problem that existing small hand-operated circular looms lack a structure for lifting and pressing the yarn, resulting in the yarn only maintaining a fixed feed height and angle during the process of being transported to the weaving area, and the inability to adjust the yarn height. This leads to significant changes in yarn tension, which in turn affects the weaving quality of the fabric.

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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A lifting guide structure for a circular loom includes a connecting seat 1, a circular loom body 2 rotatably connected to the inner side of the connecting seat 1, a support mechanism 3 fixedly connected to the top of the rear side of the connecting seat 1, and a lifting mechanism 4 fixedly connected to both sides of the top of the support mechanism 3.

[0029] The lifting mechanism 4 includes a limit rod 41, a slide groove 42, a threaded rod 43, a slide bar 44, a slider 45, a tension sensor 46, a stepper motor 47, and a microcontroller 48.

[0031] Specifically, such as Figure 3 , Figure 4 As shown, the support mechanism 3 includes a connecting shell 31, a support plate 32, a fixed shell 33, a fixed plate 34, a connecting rod 35, a limiting plate 36, and a cable outlet 37. The connecting shell 31 is fixedly connected to the rear side of the top of the connecting seat 1.

[0032] Specifically, such as Figure 3 As shown, the support plate 32 is fixedly connected to the inner side of the connecting shell 31, the fixing shell 33 is fixedly connected to the top of the support plate 32, and the fixing plate 34 is fixedly connected to the inner side of the fixing shell 33.

[0033] Specifically, such as Figure 3 , Figure 4 As shown, the connecting rod 35 is fixedly connected to the front side of the fixing plate 34, the limiting plate 36 is fixedly connected to the front side of the connecting rod 35, and the cable outlet 37 is opened on the top of the inner side of the limiting plate 36.

[0034] In this embodiment: the connecting shell 31 can connect the support mechanism 3 and the connecting seat 1; the support plate 32 can support and limit the fixed shell 33; the fixed shell 33 can support and limit the fixed plate 34; the fixed plate 34 can support and limit the connecting rod 35 and the lifting mechanism 4; the connecting rod 35 can support and limit the limiting plate 36; the limiting plate 36 can support and limit the yarn outlet hole 37; the yarn outlet hole 37 allows the yarn to pass through and connect with the circular loom body 2.

[0035] Specifically, such as Figure 2 As shown, the left slider 45 is threadedly connected to the surface of the threaded rod 43, the right slider 45 is slidably connected to the surface of the slide rod 44, and the output end of the stepper motor 47 at the bottom is fixedly connected to the top of the threaded rod 43 through the limiting rod 41.

[0036] Specifically, such as Figure 5 As shown, support rods 5 are fixedly connected to both sides of the top of the fixed plate 34, and pressure plates 6 are fixedly connected to the surface of the support rods 5.

[0037] In this embodiment: by setting the left slider 45 to be threadedly connected to the surface of the threaded rod 43, and the right slider 45 to be slidably connected to the surface of the slide rod 44, when the stepper motor 47 drives the threaded rod 43 to rotate, the slider 45 can drive the tension sensor 46 connected to it to move up and down along the direction defined by the slide rod 44. By setting the support rod 5, support is provided for the pressure plate 6. By setting the pressure plate 6, the yarn is limited by cooperating with the pressure wheel 7.

[0038] Specifically, such as Figure 5As shown, a pressure wheel 7 is rotatably connected to the top of the pressure plate 6, and torsion springs 8 are fixedly connected to both sides of the pressure wheel 7. The side of the torsion spring 8 away from the pressure wheel 7 is fixedly connected to the surface of the support rod 5.

[0039] Specifically, such as Figure 5 As shown, a throttle 9 is rotatably connected to the right side of the right support rod 5, and the left side of the throttle 9 passes through the right support rod 5 and is fixedly connected to the right side of the right torsion spring 8.

[0040] In this embodiment: by setting up a pressure roller 7, a rolling friction relationship is formed between the yarn and the pressure roller 7 when the yarn is pressured. By setting up a torsion spring 8, a suitable preload is provided to the pressure roller 7. During the yarn feeding process, the torsion spring 8 can adaptively undergo elastic deformation according to the actual tension of the yarn, thereby adjusting the pressure force of the pressure roller 7 on the yarn. By setting up a throttle 9, the operator can directly control the deformation degree of the torsion spring 8 by manually rotating the throttle 9, thereby conveniently lifting the pressure roller 7 and passing the yarn through the bottom of the pressure roller 7.

[0041] Working Principle: First, the user securely connects the circular loom body 2 to the corresponding working position via the connecting seat 1. Next, the user places the yarn on top of the tension sensor 46, ensuring it is in contact. Then, the user holds and rotates the handle 9, causing the connected torsion spring 8 to deform. This causes the pressure roller 7 to overcome the spring force of the torsion spring 8, gradually rotating and separating from the pressure plate 6, creating space for the yarn to pass through. The user can then pass one end of the yarn through the bottom area of ​​the pressure roller 7. After the yarn has passed smoothly, the user releases the handle 9. Under the elastic force of the torsion spring 8, the pressure roller 7 quickly returns to its initial position, using the pressure generated during the return process to moderately clamp the yarn, maintaining its relative stability. The user then guides the yarn through the exit hole 37 and winds it around the circular loom body 2, completing the preparation work before weaving. Then, the user can manually rotate the circular loom body 2 to start it running. The circular loom body 2 then begins weaving the yarn. During the weaving process, if the yarn becomes under-tensioned, the tension sensor 46 will transmit a corresponding signal to the connected microcontroller 48. After receiving the signal, the microcontroller 48 will quickly issue a control command to start the stepper motor 47. After receiving the command, the stepper motor 47 starts running, driving the threaded rod 43 fixedly connected to it to rotate. The slider 45 will then drive the tension sensor 46 to adjust its position up and down synchronously, changing the height of the yarn and adjusting the tension of the yarn to restore it to a suitable range. Finally, when a round of production is completed, if it is necessary to change the yarn to continue production, simply follow the above operating steps to pass the new yarn through the bottom of the pressure wheel 7 and the exit hole 37, and then wind it to the circular loom body 2 to start the next round of weaving.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
