Description

Technical Field

[0001] This utility model discloses a multifunctional circular knitting machine yarn rack, belonging to the field of knitting equipment. Background Technology

[0002] Circular knitting machines, also known as 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 processes, and strong product adaptability.

[0003] When using a circular knitting machine to produce fabric, the yarn raw material needs to be placed on the yarn frame first. Specifically, the bobbin-shaped yarn is placed onto the spindle of the yarn frame, and then the yarn is drawn out from the top of the bobbin, passing through the tension device on the yarn frame before entering the circular knitting machine for processing. In order to accommodate larger diameter bobbins, the existing yarn frames have a large distance between adjacent spindles. Although this design can accommodate large diameter bobbins, it wastes a lot of space when using small diameter bobbins. If a large number of small diameter bobbins need to be produced simultaneously, additional yarn frames are required, which is inconvenient.

[0004] In response to the above problems, a new improvement plan is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional circular knitting machine yarn rack to solve the above-mentioned problems.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a multifunctional circular knitting machine yarn frame, including a support frame, a crossbeam fixedly connected to the support frame, a plurality of spindles being provided on the crossbeam, the spindles including a plurality of fixed rods and a plurality of movable rods, the fixed rods being fixedly connected to the crossbeam, each of the movable rods being disposed between two adjacent fixed rods and rotatably connected to the crossbeam, and a positioning component being fixedly provided on the support frame, the positioning component being able to position the movable rods.

[0007] Preferably, the positioning component includes a horizontal plate and a clamping member. The horizontal plate is fixedly connected to the bracket. The clamping member includes a snap-fit ​​part and a connecting part. The snap-fit ​​part and the connecting part are fixedly connected. The connecting part is fixedly connected to the horizontal plate. The cross-section of the snap-fit ​​part is "C"-shaped. The movable rod can be embedded into the snap-fit ​​part to form a positioning.

[0008] Preferably, the crossbeam is a cylinder, and the movable rod includes a mounting part and a rotating part. The mounting part and the rotating part are fixedly connected, and the rotating part is sleeved on the crossbeam and rotatably connected to it.

[0009] Preferably, a protrusion is fixedly connected to the rotating part, and a limit block is fixedly connected to the crossbeam. The protrusion can abut against the limit block after the movable rod rotates a certain angle.

[0010] Preferably, the fixed rod is tilted upwards on the crossbeam, and the mounting part of the movable rod is also tilted upwards when the protrusion abuts against the limiting block.

[0011] Preferably, the ends of the fixing rod and the mounting part are both chamfered.

[0012] Compared with the prior art, the beneficial effects of this utility model are: By setting a rotatable movable rod, when installing larger diameter yarn bobbins, the movable rod can be retracted to increase the distance between adjacent fixed rods and provide sufficient installation space. When a large number of small diameter yarn bobbins need to be installed, the movable rod can be rotated down to provide more installation positions without the need for additional yarn frames.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0016] like Figure 1 , Figure 2 As shown, a multifunctional circular knitting machine yarn rack includes a support 1, a crossbeam 2 fixedly connected to the support 1, and several spindles mounted on the crossbeam 2. The spindles are used to place yarn bobbins and guide the yarn into the circular knitting machine for fabric production. Each spindle includes several fixed rods 3 and several movable rods 4. The fixed rods 3 are fixedly connected to the crossbeam 2, and each movable rod 4 is positioned between two adjacent fixed rods 3 and rotatably connected to the crossbeam 2. A positioning component is fixedly mounted on the support 1 to position the movable rods 4. When the yarn bobbins used for fabric production have a large diameter, the movable rods 4 are not needed. They are positioned on the support 1 using the positioning component, thus offsetting them from the fixed rods 3. In this case, the two adjacent fixed rods 3 are not used. The large spacing between rods 3 provides sufficient space for placing yarn bobbins with larger diameters. When the raw material yarn bobbins used for fabric production are small in diameter and numerous, the number of fixed rods 3 may not be enough to accommodate all the yarn bobbins. In this case, the movable rod 4 can be rotated and removed, placing it between adjacent fixed rods 3. Since the diameter of the yarn bobbins is small at this time, it can also be smoothly installed onto the spindle. Moreover, the addition of the movable rod 4 increases the number of spindles that can be used to install yarn bobbins, eliminating the need for additional yarn frames and facilitating the production process. Furthermore, production personnel can choose to place one or more movable rods 4 to work with the fixed rods 3 as needed to meet more usage scenarios.

[0017] like Figure 1 , Figure 2 and Figure 4As shown, the positioning assembly includes a horizontal plate 5 and a clamping member 6. The horizontal plate 5 is fixedly connected to the bracket 1. The clamping member 6 includes a snap-fit ​​part 61 and a connecting part 62. The snap-fit ​​part 61 and the connecting part 62 are fixedly connected. The connecting part 62 is fixedly connected to the horizontal plate 5. The cross-section of the snap-fit ​​part 61 is "C" shaped. The movable rod 4 can be embedded into the snap-fit ​​part 61 to form a positioning. The snap-fit ​​part 61 is made of a plastic material that can deform. When the movable rod 4 is not needed, it can be rotated to abut against the snap-fit ​​part 61, and then forcefully inserted into the snap-fit ​​part 61 to complete the positioning. When needed, it can be pried out.

[0018] like Figure 1 and Figure 5 As shown, the crossbeam 2 is set as a cylinder, and the movable rod 4 includes a mounting part 41 and a rotating part 42. The mounting part 41 and the rotating part 42 are fixedly connected. The rotating part 42 is sleeved on the crossbeam 2 and rotatably connected to it. When using this product, the raw material yarn bobbin is specifically sleeved on the mounting part 41. During the rotation of the movable rod 4, the rotating part 42 can be rotated by grasping the mounting part 41 with the hand.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a protrusion 7 is fixedly connected to the rotating part 42, and a limiting block 8 is fixedly connected to the crossbeam 2. The protrusion 7 can abut against the limiting block 8 after the movable rod 4 rotates a certain angle. This design restricts the rotation angle of the movable rod 4, preventing the movable rod 4 from rotating under the gravity of the yarn bobbin after the raw material yarn bobbin is installed, which would affect production. Moreover, the protrusion 7 and the limiting block 8 are on both sides of the rotating part 42, which can also restrict its sliding along the crossbeam 2, so that the movable rod 4 remains stable in the lateral direction.

[0020] Furthermore, the fixed rod 3 is tilted upwards on the crossbeam 2, and the mounting part 41 of the movable rod 4 is also tilted upwards when the protrusion 7 abuts against the limiting block 8. When the protrusion 7 abuts against the limiting block 8, that is, when the movable rod 4 can no longer rotate downwards, the tilting angle of the mounting part 41 is the same as the tilting angle of the fixed rod 3, so as to ensure consistency after the raw material yarn bobbin is installed. Moreover, the fixed rod 3 and the movable rod 4 used to install the yarn bobbin maintain a tilted posture, so that the yarn bobbin can slide down to the bottom of the fixed rod 3 or the movable rod 4 under the action of gravity, thereby avoiding detachment from the spindle.

[0021] Finally, both the ends of the fixing rod 3 and the mounting part 41 are chamfered. This design makes it easier to install the yarn tube, and the yarn tube can be quickly fitted with the help of the chamfer.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity.
