Description

Technical Field

[0001] This utility model relates to the field of yarn conveying technology, and in particular to a spandex yarn conveying mechanism. Background Technology

[0002] During the processing of spandex yarn, it needs to be transferred from the feeding end to the processing equipment area. Due to the high elasticity and tension sensitivity of spandex yarn, in order to ensure the smooth and efficient transmission of yarn, it is necessary to avoid excessive stretching and prevent tangling during the feeding process. Existing technology usually uses horizontal drive rollers to transmit the yarn.

[0003] For example, Chinese patent application number CN201821378285.2 discloses a feeding mechanism for spandex yarn, including a horizontal feeding pipe comprising a left fixed pipe and a right guide pipe. It utilizes a horizontal transmission roller inside a left connecting bracket to conduct the yarn, significantly reducing friction during transmission. The retractable left fixed pipe and right guide pipe enhance the safety of the yarn's outer surface. The entire device is highly directional and very simple and convenient to operate. However, relying solely on the horizontal transmission roller to conduct the yarn prevents the spandex yarn from being evenly distributed at the receiving end, leading to localized accumulation and compromising the quality of the finished product. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a spandex yarn conduction mechanism to solve the technical problem that the existing technology only uses a horizontally placed transmission roller to conduct the yarn, which makes it impossible for the spandex yarn to be evenly distributed at the receiving end during conduction, resulting in local accumulation and the inability to guarantee the quality of the finished product.

[0005] To achieve the above objectives, this utility model provides a spandex yarn conduction mechanism, including a base and a horizontal guide roller and a horizontal support roller disposed on the base. The gap between the horizontal guide roller and the horizontal support roller allows the spandex yarn to pass through. The base is provided with a mounting frame. The conduction mechanism further includes:

[0006] A yarn guide cylinder is provided on the horizontally placed guide roller, and the yarn guide cylinder is provided with a yarn guide channel. The surface of the yarn guide channel is a continuous wavy section with changing direction.

[0007] A guide seat is slidably mounted on the mounting frame, and the guide seat is provided with a left guide roller and a right guide roller;

[0008] A threading ball is movable on the conductive seat, and a spandex yarn passes through the middle of the threading ball;

[0009] A drive unit 1 for driving the transverse guide roller and the transverse idler roller to rotate;

[0010] Drive unit two for driving the conductive seat to slide back and forth on the mounting bracket.

[0011] Furthermore, the drive unit one includes:

[0012] A drive motor is mounted on the base, and the output end of the drive motor is connected to one side of the transverse guide roller via a synchronous belt;

[0013] A first gear is coaxially mounted on the horizontal idler roller, and a second gear is mounted on the other side of the horizontal guide roller, wherein the second gear meshes with the first gear.

[0014] Furthermore, the second driving unit includes:

[0015] A cylinder is mounted on the base, and a slider is provided at the output end of the cylinder.

[0016] A rocker arm is rotatably mounted on the mounting bracket, a slider is slidably mounted on the rocker arm, and a conductive seat is rotatably mounted on the rocker arm;

[0017] A guide rod is slidably mounted on the mounting bracket, and the guide rod is also slidably mounted on the conductive seat. A spring is sleeved on the guide rod, one end of the spring abuts against the end of the guide rod, and the other end of the spring abuts against the conductive seat.

[0018] Furthermore, the base is adjustablely provided with a fixed seat, and the cylinder is detachably mounted on the fixed seat.

[0019] Furthermore, the conductive seat is provided with a support seat, and a split arc-shaped plate is rotatably provided on the support seat, with the threading ball located in the middle of the split arc-shaped plate.

[0020] Furthermore, the gap between the left guide roller and the right guide roller corresponds to the threading ball.

[0021] Furthermore, the top of the left guide roller is provided with a flipping rod, and the top of the right guide roller is provided with a slotted block, and the flipping rod can be placed inside the slotted block.

[0022] Furthermore, both the flipping rod and the slotted block are permanent magnets, and they are magnetically attracted to each other.

[0023] The beneficial effects of this utility model are as follows: In use, the horizontal guide roller and the horizontal support roller are driven to rotate by the first drive unit, and the transmission seat is driven to slide back and forth on the mounting frame by the second drive unit. This can achieve a more uniform distribution of spandex yarn at the receiving end, avoiding local accumulation. In the process of uniform distribution, the mutual compression and friction between spandex yarns are also reduced, which reduces the risk of spandex yarn breakage due to excessive friction and improves the overall quality of spandex yarn.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0034] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0035] The first aspect of this utility model proposes a spandex yarn conduction mechanism, such as... Figure 1-6 As shown, the system includes a base 1 and a horizontal guide roller 2 and a horizontal idler roller 3 mounted on the base 1. The gap between the horizontal guide roller 2 and the horizontal idler roller 3 allows spandex yarn to pass through. The base 1 is equipped with a mounting frame 4. The transmission mechanism also includes:

[0036] A yarn guide cylinder 5 is provided on a horizontally placed guide roller 2. The yarn guide cylinder 5 is provided with a yarn guide channel, and the surface of the yarn guide channel is a continuous wavy section with changing direction.

[0037] A sliding guide seat 6 is mounted on the mounting frame 4, and a left guide roller 7 and a right guide roller 8 are provided on the guide seat 6.

[0038] The threading ball 9 is located on the conduction seat 6, and the middle of the threading ball 9 is threaded with spandex yarn;

[0039] Drive unit 1 for driving the horizontal guide roller 2 and the horizontal idler roller 3 to rotate;

[0040] Drive unit 2 for driving the transmission seat 6 to slide back and forth on the mounting bracket 4.

[0041] In this embodiment, during use, the spandex yarn passes through the gap between the horizontal guide roller 2 and the horizontal idler roller 3, then passes through the threading ball 9 and exits between the left guide roller 7 and the right guide roller 8 to the receiving end, and then the horizontal guide roller 2 and the horizontal idler roller 3 are driven to rotate by the drive unit.

[0042] At the same time, the drive unit 2 drives the transmission seat 6 to slide back and forth on the mounting frame 4, thereby driving the threading ball 9 on the transmission seat 6 to move back and forth synchronously. When the active threading ball 9 guides the spandex yarn to the left, the spandex yarn abuts against the roller surface of the left guide roller 7. When it moves to the right, the spandex yarn abuts against the roller surface of the right guide roller 8.

[0043] This allows for a more even distribution of spandex yarn at the receiving end, avoiding localized accumulation. The even distribution process also reduces mutual compression and friction between spandex yarns, lowering the risk of breakage due to excessive friction.

[0044] In this embodiment, as Figure 1 , Figure 3 As shown, the drive unit includes:

[0045] A drive motor 10 is mounted on the base 1, and the output end of the drive motor 10 is connected to one side of the transverse guide roller 2 via a synchronous belt.

[0046] Gear 11 is coaxially mounted on the horizontal idler roller 3, and gear 212 is mounted on the other side of the horizontal guide roller 2. Gear 212 meshes with gear 11. The output end of the drive motor 10 drives the horizontal guide roller 2 to rotate through the synchronous belt. The horizontal idler roller 3 is driven to rotate through the meshing gear 11 and gear 212 on the other side, thereby providing guiding traction force for the conduction of spandex yarn.

[0047] In this embodiment, as Figure 2 As shown, the second drive unit includes:

[0048] A cylinder 13 is mounted on a base 1, and a slider 14 is provided at the output end of the cylinder 13.

[0049] A swing arm 15 is rotatably mounted on the mounting bracket 4, a slider 14 is slidably mounted on the swing arm 15, and a transmission seat 6 is rotatably mounted on the swing arm 15.

[0050] A guide rod 16 is slidably mounted on the mounting frame 4 and is also slidably mounted on the transmission seat 6. A spring 17 is sleeved on the guide rod 16. One end of the spring 17 abuts against the end of the guide rod 16, and the other end of the spring 17 abuts against the transmission seat 6. During the forward extension and return stroke of the cylinder 13, the output end will drive the slider 14 to slide back and forth in the swing rod 15, which in turn drives the transmission seat 6 to slide back and forth on the mounting frame 4. This achieves the reciprocating motion of the spandex yarn guided by the threading ball 9, the left guide roller 7, and the right guide roller 8.

[0051] In this embodiment, as Figure 3 As shown, a fixed seat 18 is adjustable on the base 1, and the cylinder 13 is detachably mounted on the fixed seat 18. By adjusting the mounting position of the fixed seat 18 on the base 1, the swing amplitude of the swing arm 15 can be changed as needed.

[0052] In this embodiment, as Figure 5 As shown, the transmission seat 6 is provided with a support seat, and a split arc plate 19 is rotatably provided on the support seat. The threading ball 9 is located in the middle of the split arc plate 19. By replacing the support seat with different heights, the installation height of the threading ball 9 can be changed as needed.

[0053] In this embodiment, as Figure 4 , Figure 5 As shown, the gap between the left guide roller 7 and the right guide roller 8 corresponds to the threading ball 9.

[0054] In this embodiment, as Figure 5 , Figure 6 As shown, the top of the left guide roller 7 is provided with a flipping rod 20, and the top of the right guide roller 8 is provided with a slotted block 21. The flipping rod 20 can be placed inside the slotted block 21. Both the flipping rod 20 and the slotted block 21 are permanent magnets, and the two are attracted by magnetism to prevent the spandex yarn from separating between the left guide roller 7 and the right guide roller 8.
