Description

Technical Field

[0001] This invention relates to the field of textile processing technology, specifically to an automatic weft yarn scaffold for textile machines. Background Technology

[0002] In textile production, weft frames support and hold yarn bobbins, ensuring smooth yarn delivery to the weaving machine. Modern textile equipment typically includes electronic yarn clearers and automatic yarn breakage stop devices along the yarn path. These devices require the yarn to pass through their detection slots or sensors along a pre-defined, stable path. If the bobbin's position changes, causing the yarn to vibrate, jump, or deviate from the correct path, the yarn clearer may malfunction, misjudging good yarn as defective and cutting it, or it may fail to detect the breakage. Therefore, the placement of the yarn bobbin is a precisely designed, fixed point that cannot be arbitrarily changed to ensure the yarn can smoothly unwind and exit along its twist direction.

[0003] Because the position of the yarn bobbin remains fixed during the yarn unwinding process, the textile machine needs to be stopped after all the yarn on the bobbin has been unwound, and a new yarn bobbin needs to be replaced in the original position. This process affects the overall production efficiency. Furthermore, when the textile machine stops, yarn breaks and defects occur, which means more yarn waste and the production of substandard fabric, directly increasing production costs.

[0004] To address the aforementioned problems, we propose an automatic weft yarn scaffold for textile machines. Summary of the Invention

[0005] To address the problems in the background art, the present invention provides an automatic weft yarn scaffold for textile machines.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic weft yarn scaffold for a textile machine includes a main support column, with a support frame assembly at its top. The support frame assembly includes a base plate and a top plate, with the top plate located at the upper center of the base plate. The base plate and top plate are fixedly connected by two sets of guide rods. Two sets of lifting plates are located in the inner center of the support frame assembly, with a support rod fixedly installed on the left side of each set of lifting plates. A support shaft is fixedly installed in the center of each support rod, and the support shaft is used to support the yarn bobbin. A drive assembly is also included, which drives the two sets of lifting plates to perform synchronous lifting and sliding movements. The drive assembly includes a ball screw, which is movably installed in the inner center of the support frame assembly and is driven by a servo motor.

[0007] Preferably, the bottom of the ball screw is movably connected to the support base plate via a bearing, and the top of the ball screw is movably connected to the support top plate via a bearing.

[0008] Preferably, a nut is fixedly installed on the inner center of the lifting plate, and the nut is connected to the ball screw for transmission.

[0009] Preferably, the lifting plate is provided with sliding sleeves at the middle of both ends, and the lifting plate is slidably connected to the guide rods on both sides through the two sets of sliding sleeves.

[0010] Preferably, the servo motor is fixedly installed in the middle of the inner side of the main support column, and the servo motor is connected to the bottom of the ball screw for transmission.

[0011] Preferably, a fixing plate is provided at the bottom of the main support column.

[0012] Preferably, the head end of the support shaft is configured with a threaded structure, and a limit ring is installed at the threaded structure.

[0013] Preferably, a photoelectric sensor is provided in the center of the front of the lifting plate, and the photoelectric sensor is located in the center of the side end of the support shaft.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The automatic weft yarn loader provided by this invention can cyclically replace the yarn bobbins during use without stopping the textile machine. Furthermore, under the action of the drive component, the yarn bobbins being fed can be adjusted to the same position as the initial feeding position, maintaining the consistency of the feeding position, thereby effectively enhancing the stability of the feeding operation. This eliminates the need to adjust the sensors according to the newly installed position, reducing the labor of the workers and improving the working efficiency of the textile machine.

[0017] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: Example: Refer to Figure 1 - Figure 3 As shown, an automatic weft yarn frame for a textile machine according to this embodiment includes a main support column 1. A fixing plate 15 is provided at the bottom of the main support column 1 for fixing the weft yarn frame. The entire weft yarn frame can be firmly installed on the ground by bolts, which enhances stability.

[0018] A support frame assembly is provided at the top of the main support column 1. The support frame assembly includes a support base plate 3 and a support top plate 5. The support top plate 5 is located at the upper middle part of the support base plate 3. The support base plate 3 and the support top plate 5 are fixedly connected by two sets of guide rods 4. Two sets of lifting plates 7 are provided in the middle of the inner side of the support frame assembly. Support rods 10 are fixedly installed on the left side of each of the two sets of lifting plates 7. A support shaft 11 is fixedly installed in the middle of the support rod 10. The support shaft 11 is used to support and install the yarn bobbin 13. During use, the operator puts the yarn bobbin 13 on the support shaft 11 for stable placement.

[0019] The drive assembly is used to drive the two sets of lifting plates 7 to perform synchronous lifting and sliding movements. The drive assembly includes a ball screw 6, which is movably installed in the middle of the inner side of the support frame assembly. A nut 8 is fixedly installed in the middle of the inner side of the lifting plate 7. The nut 8 is connected to the ball screw 6 through transmission. The ball screw 6 is driven by a servo motor 2, which is fixedly installed in the middle of the inner side of the main support column 1. The servo motor 2 drives the ball screw 6 to rotate. Under the action of the transmission force, the lifting plate 7 performs lifting and sliding movements, thereby realizing the lifting and lowering adjustment of the position of the support shaft 11.

[0020] In some examples, the bottom of the ball screw 6 is movably connected to the support base plate 3 via a bearing, and the top of the ball screw 6 is movably connected to the support top plate 5 via a bearing. Under the action of the bearing, the ball screw 6 can rotate flexibly. The bottom of the ball screw 6 is connected to the output shaft of the servo motor 2 via a coupling, and the servo motor 2 drives it to rotate forward and backward. The arrangement of the servo motor 2 and the ball screw 6 can improve the accuracy of the lifting plate 7 in lifting and lowering movements, thereby ensuring that the yarn bobbin 13 being unloaded is always kept in the same location for stable storage.

[0021] A photoelectric sensor 14 is installed in the center of the front of the lifting plate 7. The photoelectric sensor 14 is located in the center of the side end of the support shaft 11. The photoelectric sensor 14 is used to detect the yarn unloading status of the yarn bobbin 13. When it is detected that all the yarn in the yarn bobbin 13 has been unloaded and it is necessary to lift and switch between the two yarn bobbins 13, the photoelectric sensor 14 sends a signal to the control system. At this time, the control system immediately starts the drive component to automatically lift and adjust the lifting plate 7. The technology of this control system and the photoelectric sensor 14 both adopt existing mature technologies, which will not be described in detail here.

[0022] In some examples, sliding sleeves 9 are provided at the middle of both ends of the lifting plate 7. The two sets of sliding sleeves 9 enable the lifting plate 7 to slide with the guide rods 4 on both sides. The guide rods 4 can limit the lifting and sliding movement of the lifting plate 7, thereby effectively enhancing the stability of the lifting plate 7 during the lifting and sliding process.

[0023] In some examples, the head end of the support shaft 11 is configured with a threaded structure, and a limit ring 12 is installed at the threaded structure. The limit ring 12 can clamp and limit the yarn bobbin 13 to prevent slippage.

[0024] In some examples, the weft yarn frame of the present invention is configured as a single-jet structure, and the support frame assembly is installed on the left side of the lifting plate 7. When double-jet is required, another set of support frame assemblies can be symmetrically installed on the right side of the lifting plate 7 to realize the use of the double-jet structure.

[0025] The working principle of this invention is: In the process of using this invention, by setting two sets of support shafts 11, during the yarn feeding process, the operator can install two sets of yarn bobbins 13 at one time, and then move the lower yarn bobbin 13 to the designated position for stable storage before the yarn feeding movement can be carried out. The yarn feeding position needs to be precisely calculated and is mostly set in the middle position of the weft yarn frame.

[0026] When installing the two sets of yarn bobbins 13, the tail of the yarn in the lower yarn bobbin 13 needs to be connected to the head of the yarn in the upper yarn bobbin 13, so that after all the yarn in the lower yarn bobbin 13 has been unloaded, the yarn in the upper yarn bobbin 13 can be unloaded to achieve a seamless connection.

[0027] When the yarn is being unloaded from the upper yarn bobbin 13, the drive assembly is activated, which simultaneously drives the lifting plate 7 to descend, so that the upper yarn bobbin 13 is lowered to the original unloading position for stable storage. At this point, the staff can replace the lower yarn spool 13 that has already completed the yarn feeding operation, and fix the yarn head end of the new yarn spool 13 to the yarn tail end located on the upper layer that is feeding yarn. After the yarn feeding of the upper yarn spool 13 is completed, the drive component is started again, thereby driving the two sets of lifting plates 7 to move upward, so that the lower yarn spool 13 is raised to the designated position for feeding yarn to continue the feeding operation. At this time, the staff can replace the upper yarn spool 13 that has completed the feeding operation.

[0028] Through the above steps, the yarn bobbin 13 can be replaced cyclically. The entire process can be completed without stopping the textile machine. Furthermore, under the action of the drive component, the yarn bobbin 13 that is currently being fed can be adjusted to the same position as the initial feeding position, maintaining the consistency of the feeding position and enhancing the stability of the feeding operation. This eliminates the need to adjust the various sensors according to the newly installed position, reducing the labor of the workers and improving the working efficiency of the textile machine. In addition, in practical applications, it takes several hours to finish unwinding all the yarn in the yarn spool 13. However, the present invention uses two sets of yarn spools 13 that are cyclically replaced, doubling the unwinding time and leaving more time. This provides a lot of flexibility for replacing the yarn spools 13, thus freeing up labor.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
