Description

Technical Field

[0001] This utility model relates to the field of fiber woven fabric processing technology, specifically to a guiding device for circular looms. Background Technology

[0002] A circular loom is an industrial device used for weaving tube fabric. The warp frame of a circular loom has many spindles, and a specified number of warp yarns are used depending on the width of the fabric and the width of the flat yarn. Before entering the circular loom, the warp yarns are crossed by the warp frame, and the weft shuttle moves in a circular motion through the crossing openings to pass through the warp yarns, thus weaving the fabric into tubes.

[0003] In the processing of woven fabrics, circular looms are often used. After the yarn on the woven fabric is formed, a guiding structure is needed to guide and collect the yarn.

[0004] However, existing devices cannot be adjusted during actual use, resulting in a single guiding direction and preventing the guiding structure from working properly. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A guide device for a circular loom includes a mounting plate. A motor is fixedly mounted on the upper left side of the mounting plate. A rotating shaft is rotatably mounted on the upper inner side of the mounting plate. A support plate is fixedly mounted on the top of the rotating shaft. A guide mechanism is provided on the upper inner side of the support plate. A tensioning mechanism is provided on the lower front side of the support plate.

[0007] The guiding mechanism includes a horizontal plate, the two ends of which are fixedly connected to the inner upper end of the support plate. A threaded sleeve is fixedly provided in the middle of the horizontal plate, and a screw is installed in the internal thread of the threaded sleeve. A knob is fixedly provided at the top of the screw. A movable plate is installed at the lower end of the screw. Limiting blocks are fixedly provided at both ends of the movable plate. Limiting grooves are opened in the inner wall of the support plate. Multiple sets of equally spaced frames are fixedly provided at the lower end of the movable plate. Rollers are rotatably installed on the inner side of the frames.

[0008] Preferably, the lower end of the screw is rotatably mounted to the middle of the upper end of the movable plate.

[0009] Preferably, the limiting block matches the limiting groove and is slidably installed.

[0010] Preferably, the tensioning mechanism includes a slide groove, which is located at the lower end of the front end of the support plate. A vertical rod is fixedly installed inside the slide groove. A spring is sleeved on the lower end of the vertical rod. A sliding plate is slidably connected to the upper end of the vertical rod. A top plate is fixedly installed at the top of the sliding plate. A tensioning roller is rotatably installed on the inner side of the top plate.

[0011] Preferably, the two ends of the spring are fixedly connected to the opposite surfaces of the slide plate and the slide groove, respectively.

[0012] Preferably, the slide plate is fitted into the slide groove and is slidably installed.

[0013] Preferably, a guide conveying roller is rotatably mounted on the inner side of the lower end of the support plate, and multiple sets of guide wheels are fixedly sleeved on the outside of the guide conveying roller.

[0014] Preferably, the output end of the motor is connected to the top end of the left-hand rotating shaft via a transmission installation.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model provides a guiding device for a circular loom. Through the guiding mechanism, the yarn is placed inside the guide wheel on the guide conveyor roller. Then, the rotating screw pushes the movable plate downward, causing the movable plate to move synchronously with the frame. The roller can then be placed inside the guide wheel, thereby limiting the yarn and preventing it from falling off. The yarn can be traction-guided between the guide conveyor roller and the roller. When it is necessary to adjust the tilt angle, the motor is started, and the motor drives the rotating shaft to rotate, causing the rotating shaft to rotate the support plate, so that a certain angle can be adjusted, thereby realizing the adjustment of the guiding direction.

[0017] 2. This utility model provides a guiding device for a circular loom. Through the tensioning mechanism, the yarn can pass through the lower end of the tensioning roller and be placed inside the guide wheel. The return of the spring can drive the slide plate to slide downward on the upright, and then the top plate can drive the tensioning roller to move down synchronously, thereby pressing down on the yarn and ensuring that the yarn is in a tensioned state, thus improving the guiding and conveying effect.

[0023] The present invention will be further described in detail below with reference to embodiments:

[0024] like Figures 1-4 As shown, this utility model provides a guide device for a circular loom, including a mounting plate 1. A motor 2 is fixedly mounted on the upper left side of the mounting plate 1. A rotating shaft 3 is rotatably mounted on the upper inner side of the mounting plate 1. A support plate 4 is fixedly mounted on the top of the rotating shaft 3. A guide mechanism 5 is provided on the upper inner side of the support plate 4. A tensioning mechanism 6 is provided on the lower front side of the support plate 4.

[0025] A guide conveyor roller 7 is rotatably installed on the inner side of the lower end of the support plate 4, and multiple sets of guide wheels 8 are fixedly sleeved on the outside of the guide conveyor roller 7.

[0026] The output end of motor 2 is connected to the top of the left-side rotating shaft 3 via a transmission system.

[0027] like Figure 3 As shown, the guide mechanism 5 includes a horizontal plate 51. The two ends of the horizontal plate 51 are fixedly connected to the inner side of the upper end of the support plate 4. A screw sleeve 52 is fixedly provided in the middle of the horizontal plate 51. A screw rod 53 is installed in the internal thread of the screw sleeve 52. A knob 54 is fixedly provided at the top of the screw rod 53. A movable plate 55 is installed at the lower end of the screw rod 53. Limiting blocks 56 are fixedly provided at both ends of the movable plate 55. Limiting grooves 57 are opened in the inner wall of the support plate 4. Multiple sets of equally spaced frames 58 are fixedly provided at the lower end of the movable plate 55. Rollers 59 are rotatably installed on the inner side of the frames 58.

[0028] The lower end of the screw 53 is rotatably mounted to the middle of the upper end of the movable plate 55.

[0029] The limiting block 56 matches the limiting groove 57 and is slidably installed.

[0030] In this design, when the movable plate 55 is moved up and down by the screw 53, the limiting block 56 will slide synchronously in the limiting groove 57, so as to improve the stability of the movement of the movable plate 55.

[0031] like Figure 4As shown, the tensioning mechanism 6 includes a slide groove 61, which is located at the lower end of the front end of the support plate 4. A vertical rod 62 is fixedly installed inside the slide groove 61. A spring 63 is sleeved on the lower end of the vertical rod 62. A sliding plate 64 is slidably connected to the upper end of the vertical rod 62. A top plate 65 is fixedly installed at the top of the sliding plate 64. A tensioning roller 66 is rotatably installed on the inner side of the top plate 65.

[0032] The two ends of the spring 63 are fixedly connected to the opposite surfaces of the slide plate 64 and the slide groove 61, respectively.

[0033] The slide plate 64 is fitted into the slide groove 61 and is slidably installed.

[0034] In this design, the tension roller 66 ensures that the yarn is always in a taut state. During the yarn guiding and conveying process, this taut state greatly improves the conveying effect and effectively avoids problems such as poor conveying and wrinkles caused by the yarn being loose, thereby improving the performance of the device.

[0035] The working principle of the guiding device for this circular loom will be explained in detail below.

[0036] like Figures 1-4 As shown, when using the guiding device for this circular loom, the yarn is first passed through the lower end of the tension roller 66 and placed inside the guide wheel 8 on the guide conveyor roller 7. Then, by rotating the knob 54, the knob 54 drives the screw 53 to rotate. Due to the threaded engagement between the screw sleeve 52 and the screw 53, the rotation of the screw 53 is converted into linear motion, which in turn pushes the movable plate 55 downward in a specific direction. During the downward movement of the movable plate 55, it drives the frame 58 to move synchronously, and the rollers 59 installed on the frame 58 move accordingly until the rollers 59 are exactly inside the guide wheel 8. At this time, the rollers 59 and the guide wheel 8 work together to limit the yarn, making it less likely for the yarn to fall off during the conveying process. In the normal guiding and conveying stage of the yarn, the yarn is guided and traction-guided between the guide conveyor roller 7 and the roller 59. The continuous rotation of the guide conveyor roller 7 and the roller 59 drives the yarn forward smoothly, while the roller 59 plays an auxiliary support and limiting role, ensuring that the yarn is always conveyed along the predetermined path. When it is necessary to adjust the tilt angle, the motor 2 is started. The motor 2 uses the rotation of the shaft 3 to further drive the support plate 4 to rotate, changing its angle and thus adjusting the guiding direction. Under the action of the spring 63's retraction force, the slide plate 64 will slowly slide down along the upright 62. The downward movement of the slide plate 64 can drive the top plate 65 to move together, and the tension roller 66 will also move down synchronously with the top plate 65. At this time, the downward-moving tension roller 66 will generate a continuous downward pressure force on the yarn below. With this downward pressure force, the yarn can always be kept in a taut state, improving the guiding and conveying effect.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
