Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a yarn frame for a circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines or circular weft knitting machines, have seen rapid development due to their numerous loop-forming systems, high speed, high output, rapid pattern changes, good fabric quality, fewer processing steps, and strong product adaptability. Before using a circular knitting machine, the yarn bobbins need to be placed on a yarn creel, which is one of the important components of the machine.

[0003] In the operation of a circular knitting machine, the yarn trellis serves to suspend yarn bobbins. A typical yarn bobbin consists of a bobbin body and yarn wound around it. The bobbin body is usually mounted on a hanging rod on the yarn trellis, and one end of the yarn is pulled out and drawn by rollers, continuously feeding the yarn into the circular knitting machine for knitting processing to form fabric. A single yarn trellis usually holds several yarn bobbins. When all the yarn on one bobbin is used up, another unused bobbin must be immediately connected.

[0004] For ease of hanging, the diameter of the yarn hanging rod is usually much smaller than that of the bobbin, making it easy to slip on. However, this also results in the bobbin not being securely installed on the hanging rod. During the process of the yarn being pulled, the bobbin will be pulled, which can easily cause the entire bobbin to fall off the hanging rod, affecting the normal operation of the circular knitting machine. Utility Model Content

[0005] The purpose of this utility model is to provide a yarn frame for a circular knitting machine in order to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a yarn rack for a circular knitting machine, comprising a frame body, wherein a plurality of yarn hanging components are provided on the frame body, the yarn hanging components comprising a limiting frame and a yarn hanging rod slidably connected inside the limiting frame, a yarn tube being sleeved on the yarn hanging rod, and an opening being provided on the limiting frame, wherein the yarn tube can extend out or enter the limiting frame through the opening.

[0007] As a further feature of this utility model, the limiting frame includes mutually parallel support bars and stop bars, the support bars and stop bars are connected by connecting bars, the support bars are fixedly connected to the frame, and the connecting bars are perpendicular to the support bars and stop bars.

[0008] As a further feature of this utility model, a groove is provided on the support bar along its length, a sliding member is slidably connected inside the groove, a connecting arm is provided on the sliding member, and the yarn hanging rod is connected to the end of the connecting arm away from the sliding member.

[0009] As a further feature of this invention, the sliding member includes a sliding pin, the end of which, away from the connecting arm, passes through a sliding groove and is connected to a limiting piece, and a bearing is connected to the sliding pin.

[0010] As a further feature of this invention, a buffer block is provided at the bottom of the connecting arm for contacting the connecting strip, and the buffer block is made of rubber material.

[0011] As a further feature of this invention, the connecting strip is recessed downward to form a groove.

[0012] As a further feature of this invention, the stop bar is slidably connected to the connecting bar.

[0013] As a further feature of this invention, the connecting strip is provided with a slide rail, and the stop bar is provided with a slider that is slidably connected inside the slide rail.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] When the yarn bobbin needs to be replaced, this invention allows the yarn bobbin to be pushed upwards, causing the yarn hanging rod to slide upwards. This allows the yarn bobbin to extend out of the limiting frame through the opening, thus releasing the restriction of the limiting frame on the yarn bobbin. This makes it easy to pull the old yarn bobbin directly off the yarn hanging rod. Then, the new yarn bobbin is inserted into the yarn hanging rod, and the yarn bobbin is released. Under the action of gravity, the yarn bobbin will automatically fall down, causing the yarn hanging rod to slide down, so that the yarn bobbin falls into the limiting frame. The limiting frame restricts the yarn bobbin, keeping it on the yarn hanging rod. The operation is convenient and simple, preventing the yarn bobbin from falling off the yarn hanging rod and ensuring the normal operation of the circular knitting machine.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 As shown, a yarn rack for a circular knitting machine includes a frame 1. Several yarn hanging components are mounted on the frame 1. Each yarn hanging component includes a limiting frame and a yarn hanging rod 2 slidably connected inside the limiting frame. A yarn bobbin 3 is fitted onto the yarn hanging rod 2, and yarn is wound on the yarn bobbin 3. An opening is provided in the limiting frame, allowing the yarn bobbin 3 to extend or enter the limiting frame through the opening. When it is necessary to replace the yarn bobbin 3, the yarn bobbin 3 can be pushed upwards, causing the yarn hanging rod 2 to slide upwards, allowing the yarn bobbin 3 to extend out of the limiting frame through the opening. This allows the limiting frame to release the restriction on the yarn bobbin 3, making it easy to pull the old yarn bobbin 3 directly off the hanging rod 2. Then, the new yarn bobbin 3 is put onto the hanging rod 2, and the yarn bobbin 3 is loosened. Under the action of gravity, the yarn bobbin 3 can fall automatically, causing the hanging rod 2 to slide down, so that the yarn bobbin 3 falls into the limiting frame. Thus, by limiting the yarn bobbin 3 through the limiting frame, the yarn bobbin 3 can be restricted to the hanging rod 2. The operation is relatively convenient and simple, which can prevent the yarn bobbin 3 from falling off the hanging rod 2 and ensure the normal operation of the circular knitting machine.

[0023] Please see Figure 2-4As shown, the limiting frame includes parallel support bars 4 and stop bars 5, which are connected by a connecting bar 6. The support bars 4 are fixedly connected to the frame 1, and the connecting bar 6 is perpendicular to the support bars 4 and stop bars 5. After the yarn bobbin 3 enters the limiting frame, the support bars 4 and stop bars 5 can limit the two ends of the yarn bobbin 3 respectively, thereby preventing the yarn bobbin 3 from falling off the hanging rod 2 and ensuring the installation stability of the yarn bobbin 3. A buffer block 12 is provided at the bottom of the connecting arm 8 to abut against the connecting bar 6. The buffer block 12 is made of rubber material. When the yarn bobbin 3 falls into the limiting frame, the buffer block 12 will collide with the connecting bar 6, and thus undergo elastic deformation to mitigate the impact. To prevent excessive impact during descent and deformation of the hanging rod 2, a groove 13 is formed by a downward indentation on the connecting strip 6. When it is necessary to push the yarn tube 3 upward, the hand can be inserted into the groove 13 to apply force. The existence of the groove 13 provides a gap between the yarn tube 3 and the connecting strip 6, making it easier to insert the hand and pushing the yarn tube 3 upward. When the yarn tube 3 is discharging yarn, the yarn on it will be continuously released under the traction of the traction mechanism. Therefore, the yarn needs to bypass the stop bar 5 before connecting with the traction mechanism, so that the existence of the stop bar 5 does not affect the normal yarn discharge of the yarn tube 3. When it is necessary to disassemble the yarn tube 3, the connection between the yarn and the traction mechanism must be cut first before disassembly.

[0024] Please see Figure 2 , Figure 3 As shown, a groove 7 is provided along the length of the support bar 4, and a sliding member is slidably connected inside the groove 7. A connecting arm 8 is provided on the sliding member, and the yarn hanging rod 2 is connected to the end of the connecting arm 8 away from the sliding member. When the yarn hanging rod 2 slides up and down, it can drive the support arm to move, so that the sliding member slides along the length of the groove 7. By limiting the sliding member through the groove 7, the sliding direction of the yarn hanging rod 2 can be limited, making the sliding of the yarn hanging rod 2 easier and smoother. The sliding member includes a sliding pin 9, which passes through the groove 7 and is connected to a limiting piece 10 at the end of the sliding pin 9 away from the connecting arm 8. A bearing 11 is connected to the sliding pin 9. The bearing 11 is a ball bearing 11. When the sliding pin 9 slides along the length of the groove 7, the bearing 11 will rub against the side wall of the groove 7, thereby generating rolling, which makes the sliding of the sliding pin 9 smoother and the sliding of the yarn hanging rod 2 more flexible and less prone to jamming.

[0025] Please see Figure 4As shown, the baffle 5 is slidably connected to the connecting strip 6, which allows the distance between the baffle 5 and the support strip 4 to be adjusted, thereby adjusting the size of the opening. This makes the limiting frame suitable for the installation of yarn tubes 3 of different lengths. The connecting strip 6 has a slide rail 14, and the baffle 5 has a slider 15 slidably connected inside the slide rail 14. When the baffle 5 is adjusted, the slider 15 will slide along the slide rail 14, making the sliding of the baffle 5 easier and smoother.
