Description

Technical Field

[0001] The utility model relates to the technical field of yarn processing, in particular to a yarn tube balloon winding prevention structure. Background Art

[0002] Warping is the process of winding a certain number of warp yarns in parallel on a warp beam or weaving beam according to the specified length and width. The warp yarns after warping are used for sizing and drawing. Warping requires that the tension of each warp yarn is equal, the distribution on the warp beam or weaving beam is even, and the arrangement of colored yarns meets the process requirements.

[0003] During the yarn warping process, the yarn will pass through the tensioner to keep a certain tension in the subsequent conveying process to ensure smooth conveying of the yarn.

[0004] During the yarn bobbin pay-off process, the yarn will rotate around the bobbin, resulting in a balloon on the rotation path of the yarn. The diameter of the balloon is larger than the rotation diameter of the yarn. In order to improve the processing efficiency, as many yarn bobbins as possible will be installed on the frame, causing the balloons of two adjacent yarn bobbins to interfere with each other. The balloon will pull the yarn, causing the yarns on the two adjacent yarn bobbins to conflict or entangle with each other, causing the two adjacent yarns to become knotted. When the knotted yarn passes through the tensioner, the yarn is easy to break. In this way, the warping equipment needs to be stopped to allow the staff to continue the yarn, which reduces the warping efficiency of the yarn. Utility Model Content

[0008] By adopting the above technical solution, when releasing the yarn, the staff installs the yarn drum on the first mounting frame, then uses the mounting assembly to install the yarn cover on the second mounting frame, uses the moving assembly to move the second mounting frame, and moves the yarn cover until the yarn drum enters the yarn cover, then passes the yarn through the avoidance port and the tensioner, and then starts the device to release the yarn. The staff uses the yarn cover to cover the yarn drum, and the yarn is restricted in the yarn cover when it rotates, so that the two adjacent yarn drums are separated, reducing the conflict or entanglement of the two adjacent yarns, reducing the possibility of yarn breakage, making the yarn drum release as stable as possible, and improving the yarn warping efficiency.

[0009] Optionally, the mounting assembly includes a fixing plate, mounting bolts and mounting nuts, wherein a plurality of fixing plates are connected to the yarn cover, the mounting bolts are passed between the fixing plate and the second mounting frame, and the mounting nuts are threadedly engaged with the mounting bolts and abut against the second mounting frame.

[0010] By adopting the above technical solution, when installing the yarn cover, the staff will pass the mounting bolt through the fixing plate and the second mounting frame, and then rotate the mounting nut to make the mounting nut press against the second mounting frame, thereby limiting the freedom of the yarn cover and realizing the installation of the yarn cover.

[0011] Optionally, the mounting assembly includes a snap-in sleeve and a snap-in claw, the snap-in sleeve is connected to the second mounting frame, the snap-in claw is connected to the yarn stop cover, the snap-in claw is made of deformable material, and a snap-in groove is provided on the snap-in sleeve. When the yarn stop cover is installed, the snap-in claw is inserted into the snap-in groove and snap-fitted with the snap-in groove.

[0012] By adopting the above technical solution, when installing the yarn cover, the staff inserts the clamping claw into the clamping joint. During this process, the clamping claw contacts the inner wall of the clamping groove and deforms until the clamping claw is clamped and engaged in the clamping groove, thereby achieving the installation of the yarn cover.

[0013] Optionally, the mounting assembly includes a fixed column, a fixed block and a rotary cylinder, the fixed column is connected to the yarn cover, the fixed column is connected with a clamping column, the end of the clamping column is connected with a clamping joint, the fixed block is connected to the second mounting frame, the fixed block is provided with a plug hole and a rotary hole, the plug hole is connected with the rotary hole, the rotary cylinder is arranged in the rotary hole, the rotary cylinder is provided with a rotary groove, the reference direction is from the opening of the rotary groove to the inner wall, the width of the rotary groove gradually decreases, when the yarn cover is installed, the fixed column is plugged into the plug hole, the clamping column is pressed against the rotary groove, and the clamping joint is located in the rotary cylinder.

[0014] By adopting the above technical solution, when installing the yarn cover, the staff inserts the fixing column into the plug-in hole so that the clamping joint enters the range of the rotary hole, and then inserts the rotary cylinder into the rotary hole so that the clamping column enters the rotary groove, and then rotates the rotary cylinder to make it rotate and descend. As the width of the rotary groove gradually decreases, the clamping column gradually presses against the rotary groove, thereby limiting the freedom of the yarn cover and realizing the installation of the yarn cover.

[0015] Optionally, an arc-shaped ring plate is connected to the inner wall of the yarn blocking cover at a position close to the avoidance opening.

[0016] By adopting the above technical solution, when the yarn rotates in the avoidance opening, there is a possibility that it will rub against the edge tip of the avoidance opening, which can easily cause the yarn to break. The staff set a friction ring plate to make the yarn transition to the avoidance opening in an arc, reducing the possibility of the yarn breaking due to grinding against the edge of the avoidance opening.

[0017] Optionally, a limiting assembly is provided on the first mounting frame, and the limiting assembly includes a mounting shaft, a mounting plate and a baffle. The mounting shaft is connected to the first mounting frame, the mounting plate is connected to the mounting shaft, and a connecting screw is connected to the baffle. The connecting screw passes through the mounting shaft and is threadedly engaged with the mounting shaft. When the yarn tube is installed, the yarn tube is sleeved on the mounting shaft and is located between the mounting plate and the baffle.

[0018] By adopting the above technical solution, when installing the yarn bobbin, the staff will sleeve the yarn bobbin on the installation shaft, and then rotate the baffle to make the connecting screw thread fit into the installation shaft, thereby restricting the yarn bobbin between the installation plate and the baffle, thereby realizing the installation of the yarn bobbin.

[0020] By adopting the above technical solution, when moving the yarn cover, the staff rotates the adjusting screw to move the moving block through the restriction of the limiting rail, thereby driving the second mounting frame to move until the yarn tube enters the yarn cover, thereby achieving the effect of moving the yarn cover.

[0021] Optionally, a positioning block is connected to the base, and when the yarn drum is located in the yarn blocking cover, the second mounting bracket abuts against the positioning block.

[0022] By adopting the above technical solution, the distance between the yarn drum and the avoidance opening cannot be too close or too far. In both cases, the yarn will further rub against the yarn cover and easily break under the action of tension. The staff uses the positioning block to abut the second mounting frame to limit the yarn drum's unwinding position in the yarn cover, so that the yarn drum can be unwinded smoothly.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When releasing the yarn, the staff installs the yarn drum on the first mounting frame, then uses the mounting assembly to install the yarn cover on the second mounting frame, uses the moving assembly to move the second mounting frame, and moves the yarn cover until the yarn drum enters the yarn cover, then passes the yarn through the avoidance port and the tensioner, and then starts the equipment to release the yarn. The staff uses the yarn cover to cover the yarn drum, and the yarn is restricted in the yarn cover when it rotates, so that the two adjacent yarn drums are separated, reducing the conflict or entanglement of the two adjacent yarns, reducing the possibility of yarn breakage, making the yarn drum release as stable as possible, and improving the yarn warping efficiency;

[0025] 2. When installing the yarn cover, the staff will insert the fixing column into the plug-in hole so that the card joint enters the range of the rotary hole, and then insert the rotary cylinder into the rotary hole so that the card connection column enters the rotary groove, and then rotate the rotary cylinder to make it rotate and descend. As the width of the rotary groove gradually decreases, the card connection column gradually presses against the rotary groove, thereby limiting the freedom of the yarn cover and realizing the installation of the yarn cover.

One end of the mounting shaft 41 is fixedly connected to the first mounting frame 12, the mounting plate 42 is fixedly connected to one end of the mounting shaft 41, and the baffle 43 is arranged at the other end of the mounting shaft 41, and a connecting screw 431 is fixedly connected to the baffle 43, and the connecting screw 431 passes through the mounting shaft 41 and is threadedly matched with the mounting shaft 41. The bobbins 2 are sleeved on the mounting shaft 41 and are located between the mounting plate 42 and the baffle 43.

[0038] When installing the yarn bobbin 2, the staff sleeves the yarn bobbin 2 on the installation shaft 41, and then rotates the baffle 43 to allow the connecting screw 431 to enter the installation shaft 41 to press against the yarn bobbin 2, thereby achieving the installation of the yarn bobbin 2.

[0039] Reference Figure 1 , Figure 2 and Figure 3The second mounting frame 13 is arranged on the base 11, and a moving assembly 5 is arranged on the base 11. The moving assembly 5 includes an adjusting screw 51, a moving block 52 and a limiting rail 53. The adjusting screw 51 is rotatably connected to the base 11, and the limiting rail 53 is fixedly connected to the base 11 and is parallel to the adjusting screw 51. The moving block 52 is fixedly connected to the second mounting frame 13, and the second mounting frame 13 is slidably fitted on the limiting rail 53. The adjusting screw 51 passes through the moving block 52 and is threadedly fitted with the moving block 52. A positioning block 111 is fixedly connected to the base 11 on the moving path corresponding to the second mounting frame 13, and the positioning block 111 is used to limit the position of the second mounting frame 13.

[0040] When moving the second mounting frame 13 , the staff rotates the adjusting screw 51 to move the moving block 52 , thereby achieving the effect of moving the second mounting frame 13 .

[0041] Reference Figure 3 and Figure 4 The tensioner 3 is mounted on the second mounting frame 13 at a position corresponding to the yarn drum 2. A yarn stopper 6 is provided at a position corresponding to the yarn drum 2 on the second mounting frame 13. The yarn stopper 6 is located between the yarn drum 2 and the tensioner 3. The yarn stopper 6 is provided with an opening at one end close to the yarn drum 2 and a clearance opening at the other end. An arc-shaped ring plate 61 is fixedly connected to the inner wall of the yarn stopper 6 at a position close to the clearance opening. The arc-shaped ring plate 61 is used to assist the arc transition yarn.

[0042] Reference Figure 3 The second mounting frame 13 is provided with a mounting assembly 7, which includes a fixing plate 71, a mounting bolt 72 and a mounting nut 73. A plurality of fixing plates 71 are fixedly connected to the yarn blocking cover 6, and two are taken as an example in this embodiment. The mounting bolt 72 is inserted between the fixing plate 71 and the second mounting frame 13, and the mounting nut 73 is threadedly engaged with the mounting bolt 72 and pressed against the second mounting frame 13.

[0043] When installing the yarn cover 6, the staff passes the mounting bolt 72 through the fixing plate 71 and the second mounting frame 13, and then rotates the mounting nut 73 until the mounting nut 73 is pressed against the second mounting frame 13, thereby limiting the degree of freedom of the yarn cover 6 and realizing the installation of the yarn cover 6.

[0044] The implementation principle of the anti-balloon entanglement structure of a yarn bobbin in Example 1 of the present application is as follows: before paying off the yarn, the staff puts the yarn bobbin 2 on the mounting shaft 41, and then rotates the baffle 43 to make the connecting nut thread engage into the mounting shaft 41 until the baffle 43 is tightly against the yarn bobbin 2, and then rotates the adjusting screw 51 to move the moving block 52, thereby driving the second mounting frame 13 to move, and moving the yarn cover 6 until the second mounting frame 13 contacts the positioning block 111. At this time, the yarn bobbin 2 is located in the yarn cover 6, and then the yarn is passed through the avoidance port and the tensioner 3 in turn, thereby completing the preparation work before the yarn bobbin 2 is paid off.

[0045] The staff uses the yarn cover 6 to cover the yarn tube 2, and the yarn is restricted in the yarn cover 6 when rotating, so that the two adjacent yarn tubes 2 are separated, the conflict or entanglement of the two adjacent yarns is reduced, the possibility of yarn breakage is reduced, and the yarn tube 2 is released as stably as possible, thereby improving the warping efficiency of the yarn.

[0046] Embodiment 2: The difference between this embodiment and embodiment 1 is that the structure of the mounting component 7 is different.

[0047] Reference Figure 5 and Figure 6 The mounting assembly 7 includes a clamping sleeve 74 and a clamping claw 75. A plurality of clamping sleeves 74 are fixedly connected to the second mounting frame 13. Two are used as an example in this embodiment. A clamping groove 741 is provided on the clamping sleeve 74. The clamping claw 75 is fixedly connected to the position of the yarn blocking cover 6 corresponding to the clamping sleeve 74. The clamping claw 75 is made of a deformable material, such as plastic, and a resisting inclined surface is provided on the clamping claw 75.

[0048] When installing the yarn cover 6, the staff inserts the clamping claw 75 into the clamping sleeve 74. During this process, the inclined surface and the inner wall of the clamping groove 741 are pressed against each other, causing the clamping claw 75 to deform until the clamping claw 75 is clamped and engaged in the clamping groove 741, thereby limiting the freedom of the yarn cover 6 and realizing the installation of the yarn cover 6.

[0049] Embodiment 3: The difference between this embodiment and embodiment 1 is that the structure of the mounting component 7 is different.

[0050] Reference Figure 7 and Figure 8 The mounting assembly 7 includes a fixed column 76, a fixed block 77 and a rotary cylinder 78. Several fixed columns 76 are fixedly connected to the yarn cover 6, and two are taken as an example in this embodiment. A clamping column 761 is fixedly connected to one end of the fixed column 76 away from the yarn cover 6, and a clamping joint 762 is fixedly connected to the clamping column 761. The fixed block 77 is fixedly connected to the position corresponding to the fixed column 76 on the second mounting frame 13, and a plug hole 771 and a rotary hole 772 are opened on the fixed block 77, and the plug hole 771 is connected to the rotary hole 772. The rotary cylinder 78 is arranged in the rotary hole 772, and a rotary groove is opened on the rotary cylinder 78. The width of the rotary groove gradually decreases from the opening of the rotary groove to the inner wall as the reference direction.

[0051] When installing the yarn cover 6, the staff will insert the fixing column 76 into the insertion hole 771 so that the clamping joint 762 is located in the rotary hole 772, and then insert the rotary cylinder 78 to make the clamping column 761 enter the rotary groove, and then rotate the rotary cylinder 78 to make the rotary cylinder 78 continue to descend until the clamping column 761 is pressed tightly in the rotary groove, thereby limiting the freedom of the yarn cover 6 and realizing the installation of the yarn cover 6.
