Description

Technical Field

[0001] This utility model relates to the field of warping machine technology, and in particular to a warping machine dividing device. Background Technology

[0002] Traditional warping machines require manual labor to extract yarns or fabrics from spindles or bobbins and straighten them one by one before inserting the yarn ends into the machine. Because the yarns are very fine, it is difficult for manual labor to straighten multiple yarns quickly, and finding the yarn ends is even more laborious and time-consuming, which prolongs the preparation time before the warping machine starts working and greatly reduces the efficiency of the warping machine.

[0003] For example, Chinese patent CN221877285U proposes a yarn separating device for a warping machine. This device places the yarn spool on the separating device, straightens the yarn through a clamp, separates the yarn through a yarn separator, and then cuts the separated yarn through a yarn cutting device, with the cut point designated as the yarn end. This achieves the effect of assisting manual separation of the yarn quickly. However, after a long period of separation, the yarn ends or impurities attached to the yarn are prone to adhere to the yarn separator, affecting the separation operation of the yarn separator. Therefore, we propose a yarn separating device for a warping machine. Utility Model Content

[0004] The purpose of this invention is to provide a wire separating device for a warping machine, which facilitates the reversal and cleaning of the wire separating device to ensure its normal operation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a yarn separating device for a warping machine, comprising a main support frame, an annular groove on the front and rear sides of the main support frame, a connecting frame installed on the left and right sides of the main support frame, a yarn frame and a support frame connected to the other side of the connecting frame, a buckle installed on the yarn frame, a yarn bobbin rotatably connected to the buckle, and a clamping and cutting assembly installed on the right support frame. Two frame plates are installed on the main support frame, and an inverted U-shaped frame is movably installed on the annular groove. A driving assembly for driving the inverted U-shaped frame to move within the annular groove is installed on the frame plate. A connecting bushing is slidably connected to the inner side of the inverted U-shaped frame, and a yarn separating assembly is rotatably connected between the two connecting bushings. A bolt with one end passing through the connecting bushing and threadedly connected to the yarn separating assembly is threadedly connected to the inverted U-shaped frame.

[0006] By adopting the above technical solution, one end of the yarn on the yarn bobbin is pulled out and fixed using a clamping and cutting assembly. Then, the drive assembly is activated, causing the yarn-separating assembly between the two inverted U-shaped frames to move along the annular groove, combing the yarn on the main support frame and quickly untangling it. The clamping and cutting assembly then cuts the untangled yarn, positioning the yarn end at the break point, thus assisting manual untangling of the yarn quickly. After prolonged use, the yarn-separating assembly may accumulate yarn ends or impurities. In this case, the bolts are removed, allowing the connecting bushing to move the yarn-separating assembly upwards. The yarn-separating assembly then rotates inside the connecting bushing, reversing its direction. Finally, the bolts re-fix the reversed yarn-separating assembly to the connecting bushing on the inverted U-shaped frame, ensuring the normal operation of the yarn-separating assembly. Furthermore, the reversed yarn-separating assembly can be cleaned from the top, making maintenance more convenient.

[0007] A further feature of this invention is that the clamping and cutting assembly includes a lower pressure plate vertically slidably connected to the inner wall of the support frame, a support spring mounted on the lower pressure plate, an upper pressure plate connected to the other side of the support spring, a guide post connected to the lower pressure plate and passing through the support spring and the upper pressure plate in sequence, a cylinder mounted on the support frame, a connecting rod mounted on the upper pressure plate, and a slitting blade mounted on the other side of the connecting rod.

[0008] A further feature of this invention is that the output end of the cylinder is fixedly connected to the upper pressure plate, and the upper pressure plate does not contact the inner wall of the support frame.

[0009] By adopting the above technical solution, when one end of the yarn is fixed, the cylinder is activated, causing the lower pressure plate to move downward along the inner wall of the support frame with the upper pressure plate until the yarn is fixed between the lower pressure plate and the bottom wall of the support frame. When the unrolled yarn is cut, the cylinder continues to operate, causing the upper pressure plate to squeeze the lower pressure plate. At this time, the support spring is compressed, which in turn causes the connecting rod to drive the slitting blade to move downward and cut the yarn.

[0010] A further feature of this invention is that both the bottom of the lower pressure plate and the inner bottom wall of the support frame are designed to increase resistance. By adopting the above technical solution, the stability of yarn clamping is improved.

[0011] A further feature of this invention is that the drive assembly includes a drive shaft rotatably connected between two frame plates, a motor mounted on one of the frame plates and driving the drive shaft to rotate, and a telescopic rod mounted on the outside of the drive shaft.

[0012] A further feature of this invention is that the other side of the telescopic rod is hinged to the top of the inverted U-shaped frame.

[0013] By adopting the above technical solution, the motor starts and drives the rotating shaft to rotate, the rotating shaft drives the telescopic rod to swing, and the telescopic rod drives the yarn separating components inside the two inverted U-shaped frames to move along the annular groove, so that the yarn separating pieces sweep across the yarn surface, achieving the effect of combing the yarn.

[0014] A further feature of this invention is that the branching assembly includes a connecting bushing slidably connected to the inner side of the inverted U-shaped frame, a rotating shaft rotatably connected between the two connecting bushings, a strip plate installed outside the rotating shaft, and branching pieces installed on the upper and lower sides of the strip plate.

[0015] A further feature of this invention is that the bolt passes sequentially through the inner wall of the inverted U-shaped frame and the connecting bushing to be threadedly connected to the rotating shaft.

[0016] A further feature of this invention is that a screw hole adapted to the bolt is provided on the inner wall of the inverted U-shaped frame and the connecting bushing, and two screw holes adapted to the bolt are provided on the rotating shaft.

[0017] By adopting the above technical solution, after the splitter plate has accumulated wire ends or impurities after long-term operation, the bolts can be removed, allowing the connecting bushing to drive the rotating shaft to move upward inside the inverted U-shaped frame, giving the strip plate enough room to rotate. Then, the strip plate is rotated to reverse the direction of the top and bottom splitter plates. Finally, the bolts are used to fix the reversed strip plate and connecting bushing back to the inverted U-shaped frame, ensuring the normal operation of the splitter plate. Furthermore, the splitter plate that has been moved to the top can be cleaned directly from the top, making maintenance more convenient.

[0018] A further feature of this invention is that multiple buckles are provided on the yarn frame, with two buckles forming a group, and the yarn bobbin rotates...

[0019] It is dynamically connected between two clips.

[0020] By adopting the above technical solution, it is easy to fix multiple groups of yarns for yarn separation.

[0021] The beneficial effects of this utility model are:

[0022] 1. Pull one end of the yarn from the yarn bobbin and fix it with the clamping and cutting assembly. Then, start the drive assembly to move the yarn separating assembly between the two inverted U-shaped frames along the annular groove to comb the yarn on the main support frame and quickly straighten the yarn. Then, the clamping and cutting assembly cuts the straightened yarn and positions the yarn end at the cut point to assist manual straightening of the yarn quickly.

[0023] 2. After prolonged operation, if the branching assembly accumulates wire ends or impurities, remove the bolts to allow the connecting bushing to move the branching assembly upwards. Then, allow the branching assembly to rotate inside the connecting bushing to reverse its direction. Finally, re-secure the reversed branching assembly and connecting bushing to the inverted U-shaped frame with the bolts to ensure the normal operation of the branching assembly. The reversed branching assembly can also be cleaned from the top, making maintenance more convenient. Attached Figure Description

Detailed Implementation

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1-3 This utility model provides a wire separating device for a warping machine, including a main support frame 1, annular grooves 9 formed on the front and rear sides of the main support frame 1, connecting frames 2 installed on the left and right sides of the main support frame 1, and a wire frame connected to the other side of the connecting frame 2.

[0031] The main support frame 1 has two frame plates 5 installed on it. An inverted U-shaped frame 10 is movably installed on the annular groove 9. A drive assembly 11 is installed on the frame plate 5 to drive the inverted U-shaped frame 10 to move in the annular groove 9. A connecting bushing 14 is slidably connected to the inner side of the inverted U-shaped frame 10. A wire splitting assembly 12 is rotatably connected between the two connecting bushings 14. A bolt 13 is threadedly connected to the inverted U-shaped frame 10, with one end passing through the connecting bushing 14 and threadedly connected to the wire splitting assembly 12.

[0032] Pull out one end of the yarn on the yarn spool 8 and fix it with the clamping and cutting assembly 6. Then, start the drive assembly 11 to move the yarn separating assembly 12 between the two inverted U-shaped frames 10 along the annular groove 9 to comb the yarn on the main support frame 1 and quickly straighten it. Then, the clamping and cutting assembly 6 cuts the straightened yarn and positions the yarn end at the cut point to assist manual straightening of the yarn quickly. After long-term operation, the yarn separating assembly 12 may have yarn ends or impurities attached. At this time, remove the bolt 13 to allow the connecting bushing 14 to move the yarn separating assembly 12 upward. Then, allow the yarn separating assembly 12 to rotate inside the connecting bushing 14 to realize the reversal of the yarn separating assembly 12. Finally, the bolt 13 re-fixes the reversed yarn separating assembly 12 and the connecting bushing 14 onto the inverted U-shaped frame 10 to ensure the normal operation of the yarn separating assembly 12. The reversed yarn separating assembly 12 can be cleaned from the top, making maintenance more convenient.

[0033] The clamping and cutting assembly 6 includes a lower pressure plate 61 vertically slidably connected to the inner wall of the support frame 4, a support spring 62 mounted on the lower pressure plate 61, an upper pressure plate 63 connected to the other side of the support spring 62, a guide post 64 connected to the lower pressure plate 61 and passing through the support spring 62 and the upper pressure plate 63 in sequence, a cylinder 65 mounted on the support frame 4, a connecting rod 66 mounted on the upper pressure plate 63, and a slitting blade 67 mounted on the other side of the connecting rod 66. The output end of the cylinder 65 is fixedly connected to the upper pressure plate 63. The upper pressure plate 63 does not contact the inner wall of the support frame 4. When fixing one end of the yarn, the cylinder 65 is activated, causing the lower pressure plate 61 to move downward along the inner wall of the support frame 4 with the upper pressure plate 63 until the yarn is fixed between the lower pressure plate 61 and the inner bottom wall of the support frame 4. When cutting the unrolled yarn, the cylinder 65 continues to operate, causing the upper pressure plate 63 to squeeze the lower pressure plate 61. At this time, the support spring 62 is compressed, which causes the connecting rod 66 to drive the slitting blade 67 to move down and cut the yarn.

[0034] The bottom of the lower pressure plate 61 and the inner bottom wall of the support frame 4 are both designed to increase resistance, thereby improving the stability of yarn clamping.

[0035] The drive assembly 11 includes a drive shaft 111 rotatably connected between two frame plates 5, a motor 112 mounted on one of the frame plates 5 and driving the drive shaft 111 to rotate, and a telescopic rod 113 mounted on the outside of the drive shaft 111. The other side of the telescopic rod 113 is hinged to the top of the inverted U-shaped frame 10. When the motor 112 starts, it drives the drive shaft 111 to rotate. The drive shaft 111 drives the telescopic rod 113 to swing. The telescopic rod 113 drives the yarn separating assembly 12 on the inner side of the two inverted U-shaped frames 10 to move along the annular groove 9, so that the yarn separating piece 121 sweeps across the yarn surface, achieving the effect of combing the yarn.

[0036] The branching assembly 12 includes a connecting bushing 14 slidably connected to the inner side of the inverted U-shaped frame 10, a rotating shaft 122 rotatably connected between the two connecting bushings 14, a strip plate 123 installed outside the rotating shaft 122, and branching pieces 121 installed on the upper and lower sides of the strip plate 123. A bolt 13 passes sequentially through the inner wall of the inverted U-shaped frame 10 and the connecting bushing 14 and is threadedly connected to the rotating shaft 122. The inner wall of the inverted U-shaped frame 10 and the connecting bushing 14 have a threaded hole adapted to the bolt 13, and the rotating shaft 122 has two threaded holes adapted to the bolt 13. The branching pieces 121 are designed to withstand long-term use.

[0037] After work, if there are loose threads or impurities, remove bolt 13 to allow the connecting bushing 14 to move the rotating shaft 122 upward inside the inverted U-shaped frame 10, giving the strip plate 123 sufficient room to rotate. Then rotate the strip plate 123 to reverse the direction of the top and bottom dividing pieces 121. Finally, bolt 13 re-fixes the reversed strip plate 123 and connecting bushing 14 onto the inverted U-shaped frame 10, ensuring the normal operation of the dividing pieces 121. The dividing pieces 121 that have been moved to the top can be cleaned directly from the top, making maintenance more convenient.

[0038] Multiple buckles 7 are provided on the wire frame 3, with two buckles 7 forming a group. The yarn spool 8 is rotatably connected between two buckles 7, which facilitates fixing multiple groups of yarn for splitting.
