Description

Technical Field

[0001] This utility model relates to the field of circular knitting machine technology, specifically to a fabric support mechanism for a circular knitting machine. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, have developed rapidly and are widely used due to their multiple loop-forming systems, high speed, high output, fast pattern changes, good fabric quality, fewer processes, and strong product adaptability.

[0003] The weaving mechanism of the circular knitting machine weaves the fabric. The woven fabric falls along the cylinder of the circular knitting machine and is then clamped and pulled by the two winding rollers of the winding machine's traction mechanism, finally winding onto the take-up roller of the winding machine. A fabric support mechanism is provided between the weaving mechanism and the winding rollers. The fabric support mechanism includes a fabric support frame and a fabric cutting mechanism. The fabric support frame is rotatably fixed to the frame of the circular knitting machine via a connector. The central axis of the fabric support frame coincides with the central axis of the cylinder (fabric). The fabric cutting mechanism is fixed to the frame of the winding machine and connected to the fabric support frame.

[0004] During operation, the drive mechanism of the circular knitting machine rotates the cylinder and fabric, while the drive mechanism of the fabric winding machine drives the fabric support frame and the fabric cutting mechanism to rotate synchronously with the fabric. The fabric woven by the knitting mechanism falls in a cylindrical shape under the traction mechanism, remaining concentric with the cylinder of the circular knitting machine. The fabric support frame, set concentrically with the fabric, stretches the fabric, transforming it from a cylindrical shape into a layered shape. Then, the fabric cutting blade of the fabric cutting mechanism cuts the fabric at the folds, creating a fabric width. The opened fabric slowly unfolds and is finally wound up by the take-up roller of the fabric winding machine.

[0005] The inventors of this application discovered that due to the existence of machining errors and assembly errors in the parts, the fabric support frame, the syringe, and the fabric will be out of sync. When the fabric support frame rotates, it will wobble, causing the cut fabric to have a weft skew problem and making the fabric cut by the fabric slitting knife not straight. Utility Model Content

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0049] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", 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 this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0050] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0051] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0052] As described in the background section of this application, the drive mechanism of the circular knitting machine drives the cylinder and fabric to rotate, while the drive mechanism of the fabric winding machine drives the fabric support frame and the fabric cutting mechanism to rotate synchronously with the fabric. The fabric woven by the knitting mechanism falls in a cylindrical shape under the traction of the traction mechanism, with the fabric and the circular knitting machine cylinder remaining concentric. The fabric support frame is concentrically positioned with the fabric, spreading it out and transforming it from a cylindrical shape into a layered shape. Then, the fabric cutting blade of the fabric cutting mechanism cuts the fabric at the folds, creating a fabric width. The opened fabric slowly unfolds and is finally wound up by the take-up roller of the fabric winding machine.

[0053] The inventors of this application discovered that due to the existence of machining errors and assembly errors in the parts, the fabric support frame, the syringe, and the fabric will be out of sync. When the fabric support frame rotates, it will wobble, causing the cut fabric to have a weft skew problem and making the fabric cut by the fabric slitting knife not straight.

[0054] To address the aforementioned problems, the inventors of this application have proposed a technical solution, the specific embodiments of which are as follows:

Figure 8 As described in the embodiments of this utility model Figure 7 Enlarged view of point D in the image.

[0056] like Figures 1 to 8 As shown, the fabric support mechanism of the circular knitting machine in this embodiment includes: a fixed bracket 1, a fabric support frame 2, a connecting rod 3, a connecting mechanism 4, and a fabric cutting mechanism 5.

[0057] The fixed bracket 1 is fixedly installed on the frame of the large circular knitting machine.

[0058] The connecting rod 3 is set horizontally, and the outer end of the connecting rod 3 is connected to the frame of the large circular knitting machine.

[0059] The fabric support frame 2 is provided with a central shaft 21, which is set vertically.

[0060] The bottom end of the central shaft 21 of the fabric support frame 2 is fixedly connected to the inner end of the connecting rod 3, and the top end of the central shaft 21 is movably connected to the fixed bracket 1 through the connecting mechanism 4. The central axis of the central shaft 21 coincides with the central axis of the large circular knitting machine cylinder, that is, the central axis of the central shaft 21 coincides with the central axis of the tubular fabric 100. The connecting mechanism 4 allows the fabric support frame 2 to rotate relative to the fixed bracket 1, and the connecting mechanism 4 also allows the fabric support frame 2 to move horizontally relative to the fixed bracket 1.

[0061] The fabric cutting mechanism 5 is fixedly mounted on the fabric support frame 2, and the fabric cutting mechanism 5 is slidably connected to the connecting rod 3. The fabric cutting mechanism 5 is located at the traction roller shaft 200 of the fabric rolling machine and is used to cut the fabric spread out by the fabric support frame 2.

[0062] In this embodiment, the fabric support frame is connected to the fixed support via a connecting mechanism, forming a floating movable connection. The fabric support frame can rotate relative to the fixed support and move horizontally relative to it, ensuring that the fabric support frame remains horizontal. The traction roller pulls the fabric through the fabric support frame, and after the fabric support frame expands the tubular fabric, the fabric has a considerable inward contraction force. When the fabric support frame and the tubular fabric (needle cylinder) are not concentric, under the action of the fabric's contraction force, the fabric support frame translates relative to the fixed support, thereby keeping the fabric support frame and the fabric (needle cylinder) concentric. This eliminates the problem of misalignment between the fabric support frame and the fabric caused by assembly and processing errors. The fabric support frame will not wobble when rotating, and the cut fabric will not have weft skew problems after unfolding, improving the quality of fabric cutting.

[0063] The fabric cutting mechanism is fixedly mounted on the fabric support frame and slidably connected to the connecting rod. The relative position of the fabric cutting mechanism and the fabric support frame remains unchanged and stable, so that the fabric cutting blade of the fabric cutting mechanism cuts the fabric in a straight line without tilting.

[0064] As can be seen from the above, the fabric supporting mechanism of the circular knitting machine in this embodiment comprises a fixed bracket, a fabric supporting frame, a connecting rod, a connecting mechanism, and a fabric cutting mechanism. The fixed bracket is mounted on the circular knitting machine frame, and the connecting rod is mounted on the fabric rolling machine frame. The central axis of the fabric supporting frame is connected to the connecting rod and forms a movable connection with the fixed bracket through the connecting mechanism, allowing the fabric supporting frame to move horizontally relative to the fixed bracket. The fabric cutting mechanism is fixedly mounted on the fabric supporting frame and slidably connected to the connecting rod. In this embodiment, the fabric supporting frame of the circular knitting machine is movably connected to the fixed bracket through the connecting mechanism, allowing it to translate relative to the fixed bracket. This keeps the fabric supporting frame horizontal and prevents it from swaying during rotation, ensuring that the cut fabric will not have weft skew after unfolding. The fabric cutting mechanism is fixed on the fabric supporting frame and slidably connected to the connecting rod. The relative position of the cutting blade of the fabric cutting mechanism and the fabric supporting frame remains unchanged, ensuring that the fabric is cut straight and not tilted when opening the fabric width.

[0065] Optional, such as Figure 2 , Figure 3 and Figure 8 As shown, the fabric support mechanism of the large circular knitting machine in this embodiment includes a connecting mechanism 4, which comprises a connecting bushing 41, a movable bracket 42, and a movable pressure plate 43.

[0066] The top end of the connecting bushing 41 is connected to the fixed bracket 1.

[0067] The movable support 42 includes: a connecting column 421 and a rectangular frame 422.

[0068] The connecting post 421 is set at the top of the rectangular frame 422. The connecting post 421 of the movable bracket 42 is fixedly connected to the bottom end of the connecting bushing 41. The movable bracket 42 has a bracket hole 423 on the bottom plate of the rectangular frame 422.

[0069] The bottom of the movable pressure plate 43 is provided with a protruding post 431. The outer diameter of the protruding post 431 is smaller than the diameter of the support hole 423 of the movable bracket 42. The length of the protruding post 431 is greater than the thickness of the bottom plate of the rectangular frame 422. The outer diameter of the movable pressure plate 43 is greater than the diameter of the support hole 423.

[0070] The protruding post 431 of the movable pressure plate 43 passes through the bracket hole 423 of the movable bracket 42 and extends out of the bottom plate of the rectangular frame 422. The bottom end of the protruding post 431 is connected to the central axis 21 of the fabric support frame 2, so that a certain gap is formed between the central axis 21 and the movable bracket 42, so that the fabric support frame 2 and the fixed bracket 1 form a floating movable connection, and the fabric support frame 2 can be translated relative to the movable bracket 42 (fixed bracket 1).

[0071] Furthermore, in this embodiment, the fabric support mechanism and connecting mechanism 4 of the large circular knitting machine also include: a connecting seat 44 and a pressure plate screw 45.

[0072] The central shaft 21 of the fabric support frame 2 is fixedly connected to the bottom end of the connecting seat 44, and the top surface of the connecting seat 44 is provided with a first threaded hole 441.

[0073] The movable pressure plate 43 is provided with a through-hole. The pressure plate screw 45 passes through the through-hole of the movable pressure plate 43 and engages with the first threaded hole 441 of the connecting seat 44. When the pressure plate screw 45 is tightened, the movable pressure plate 43 is connected to the connecting seat 44.

[0074] Furthermore, in this embodiment, the fabric support mechanism and connecting mechanism 4 of the large circular knitting machine also include a receiving tray 46.

[0075] The receiving tray 46 is mounted on the pressure plate screw 45 and is located between the protruding post 431 of the movable pressure plate 43 and the connecting seat 44. The inner diameter of the receiving tray 46 is greater than the length of the base plate of the rectangular frame 422 of the movable bracket 42.

[0076] In this embodiment, the central axis of the fabric support frame is connected to the connecting seat, the protruding column of the movable pressure plate passes through the support hole of the movable bracket, and the connecting seat, the receiving tray and the movable pressure plate are connected and fixed by pressure plate screws.

[0077] The outer diameter of the protruding column of the movable pressure plate is smaller than the diameter of the support hole of the movable bracket, and the length of the protruding column is greater than the thickness of the base plate of the rectangular frame. A certain clearance is left between the top surface of the receiving tray and the bottom surface of the movable bracket, allowing the movable pressure plate to move horizontally relative to the movable bracket within the support hole. In other words, the fabric support frame rests on the movable bracket via the movable pressure plate, keeping it horizontal and allowing it to move horizontally relative to the fixed bracket. The fabric support frame will not wobble during rotation. When the fabric support frame is not concentric with the fabric (cylinder of the large circular knitting machine), under the inward shrinkage force of the fabric, the fabric support frame will move horizontally until it is concentric with the fabric, preventing weft skew in the cut fabric.

[0078] Because the movable pressure plate is movably inserted into the bracket hole of the movable support, the protruding post of the movable pressure plate will rub against the rectangular frame of the movable support. A receiving tray is set below the movable support to catch the metal powder that may be generated when the movable pressure plate rubs against the movable support, preventing the metal powder generated by the friction of the parts from falling onto the fabric and contaminating it.

[0079] Furthermore, in this embodiment, the fabric support mechanism and connecting mechanism 4 of the large circular knitting machine also include a connecting screw 47 and a connecting nut 48.

[0080] The top end of the connecting screw 47 passes through the fixing hole of the fixing bracket 1, and two connecting nuts 48 are engaged with the connecting screw 47, located above and below the fixing bracket 1 respectively, so that the position of the connecting screw 47 is adjustable and fixed on the fixing bracket 1.

[0081] The top end of the connecting bushing 41 is connected to the bottom end of the connecting screw 47.

[0082] Optional, such as Figure 5 and Figure 6 As shown, the fabric support mechanism of the large circular knitting machine in this embodiment, the fabric support frame 2 further includes: a first connecting plate 22.

[0083] The central shaft 21 of the fabric support frame 2 is provided with a limiting plane, and the fabric support frame 2 is provided with a second threaded hole 211 at the limiting plane of the central shaft 21.

[0084] The first connecting plate 22 is T-shaped and has a first elongated hole 221 and a second elongated hole 222.

[0085] The fixing screw passes through the first elongated hole 221 of the first connecting plate 22 and engages with the second threaded hole 211 of the central shaft 21, so that the first connecting plate 22 is connected to the central shaft 21 of the fabric support frame 2 in an adjustable position.

[0086] The fixing screw passes through the second elongated hole 222 of the first connecting plate 22 and engages with the threaded hole of the connecting rod 3, so that the first connecting plate 22 (cloth support frame) is connected to the connecting rod 3 in an adjustable position.

[0087] Furthermore, in this embodiment, the fabric support mechanism of the large circular knitting machine has a limiting slot 23 on the fabric support frame 2. The first connecting plate 22 is embedded in the limiting slot 23 of the fabric support frame 2 and connected to the central shaft 21, so that the first connecting plate 22 is more stable on the fabric support frame 2.

[0088] Optionally, in this embodiment, the fabric support mechanism and fabric cutting mechanism 5 of the large circular knitting machine include: a fixed base 51, a drive motor 52, a fabric cutting knife 53, and a second connecting plate 54.

[0089] The fixing seat 51 is fixedly installed on the cloth support frame 2.

[0090] The drive motor 52 is mounted on the fixed base 51, and the fabric cutting knife 53 is connected to the output shaft of the drive motor 52. The drive motor 52 drives the fabric cutting knife 53 to rotate, and the fabric cutting knife 53 is used to cut the fabric when rotating.

[0091] The top end of the second connecting plate 54 is mounted on the fixed base 51, and the bottom end of the second connecting plate 54 is slidably connected to the connecting rod 3.

[0092] Furthermore, in this embodiment, the connecting rod 3 of the fabric support mechanism of the large circular knitting machine is square.

[0093] The bottom end of the second connecting plate 54 is provided with a sliding groove 541. The sliding groove 541 of the second connecting plate 54 is slidably engaged on the connecting rod 3, so that the second connecting plate 54 and the connecting rod 3 can be slidably connected, and the fabric cutting knife 53 does not deflect relative to the connecting rod 3, so that it can cut straight during fabric cutting.

[0095] Furthermore, "above," "on top of," and "above" the first feature in relation to the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" the first feature in relation to the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
