Description

Technical Field

[0001] The utility model relates to the technical field of knitting equipment, in particular to a wire feeding mechanism. Background Art

[0002] A flat knitting machine is a weaving equipment used for knitting production and is widely used in clothing, home textiles and other fields. Its main working principle is to form knitted fabrics by moving the coils on the needles and interlacing them with each other. The needles are arranged horizontally in the flat knitting machine. The finished width of the fabric is usually wider, which is suitable for large-area flat fabrics. With the development of technology, flat knitting machines are developing towards intelligence and automation. Modern flat knitting machines not only improve production efficiency, but also can achieve personalized customization through digital design to meet the market demand for diversified and personalized products.

[0003] The wire feed mechanism is an essential part of a flat knitting machine. It's primarily used to feed the wire, passing it through the base coil and pulling it through to achieve base weaving. After weaving is complete, the wire feed mechanism is also responsible for retrieving the wire for the next feeding operation. Typically, a common wire feed mechanism consists of a base plate and a take-up reel. By winding the wire around the take-up reel and driving it to rotate, the wire is guided to deliver or retract the wire.

[0004] However, in actual applications, the current wire feeding mechanism still has some defects. For example, the steel wire is unstable during the feeding process. Specifically, when the wire is fed by the take-up reel, the front end of the steel wire will be subject to the resistance formed by the front-end equipment, which can easily cause the steel wire to slip relative to the take-up reel, causing the steel wire to loosen the take-up reel; on this basis, the steel wire may further slip and be entangled on the rotating shaft of the take-up reel, causing the take-up reel to get stuck, and then causing damage to the equipment. Therefore, there is still much room for improvement in the stability of the steel wire during transportation.

[0005] The above information is presented as background information only to assist with an understanding of the present disclosure and is not a determination or admission that any of the above may be applicable as prior art with respect to the present disclosure. Utility Model Content

[0017] Preferably, the belt assembly comprises:

[0035] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be understood that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component. When a component is considered to be "disposed on" another component, it may be directly disposed on the other component or there may be a centrally located component.

[0037] In addition, the terms "long", "short", "inside", "outside", etc. that indicate orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention. They do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientation structure, and should not be understood as a limitation of the present invention.

[0038] The following is combined with Figure 1-5 The technical solution of the utility model is further illustrated through specific implementation methods.

[0039] Reference Figure 1 The utility model discloses a wire feeding mechanism, which mainly includes a base plate 1 and a wire take-up drum 2 rotatably arranged on the base plate 1, wherein the wire take-up drum 2 is provided with a rotating shaft, which can be installed on the base plate 1 through a bearing. The base plate 1 plays a supporting role, and the wire take-up drum 2 plays a role in winding and accommodating the steel wire. By rotating the wire take-up drum 2, the steel wire can be wound or fed out to achieve the function of transporting the steel wire.

[0040] In order to improve the stability of the steel wire during transportation, the wire feeding mechanism also includes a belt assembly 3 and a friction protrusion 4; wherein, the belt assembly 3 is arranged on the base plate 1 and is arranged adjacent to the wire take-up drum 2. The belt assembly 3 is wrapped around one side of the wire take-up drum 2 and is used to press the steel wire to the peripheral surface of the wire take-up drum 2 under the action of tension. At the same time, the friction protrusion 4 is arranged on the peripheral surface of the wire take-up drum 2 and the belt assembly 3. The friction protrusion 4 is used to lift the steel wire to increase the friction on the steel wire and reduce the possibility of the steel wire slipping.

[0041] It should be explained that before the steel wire is fed out and wound up, one end of the steel wire needs to be fixed on the take-up drum 2, so that one end of the steel wire can be kept from loosening, which is conducive to the subsequent unwinding and winding actions.

[0042] Based on the above structural setting, under the joint action of the friction protrusion 4 and the belt assembly 3, the belt assembly 3 can firstly fit the steel wire tightly to the take-up drum 2 to tighten the steel wire. At the same time, the friction protrusion 4 can also increase the friction on the steel wire, thereby making the steel wire less likely to slip, and the stability of the steel wire during feeding is optimized and improved.

[0043] Reference Figure 2 In one embodiment, the friction protrusion strip can be made of metal, and the friction protrusion part 4 is integrally connected to the take-up drum 2. The friction protrusion part 4 extends along the thickness direction of the take-up drum 2 and one side of the friction protrusion part 4 is raised compared to the peripheral surface of the take-up drum 2. At this time, the raised part of the friction protrusion part 4 can lift the coil, so that the coil changes from a circular winding trajectory to a polygonal winding trajectory, thereby increasing the friction on the steel wire and preventing the steel wire from sliding loose.

[0044] It should be noted that there is more than one way to set the friction protrusion 4. In other embodiments, the friction protrusion 4 can also be one of a silicone strip, a rubber strip and a plastic strip. In this embodiment, the friction protrusion 4 uses a silicone strip as an example.

[0045] Reference Figure 3 When setting the friction protrusion 4, a mounting groove 21 can be set on the peripheral side of the take-up drum 2, wherein the mounting groove 21 is recessed and arranged on the peripheral side surface of the take-up drum 2, and the mounting groove 21 extends along the thickness direction of the take-up drum 2; on this basis, the cross-sectional profile of the mounting groove 21 is an incomplete circular profile, and accordingly, the friction protrusion 4 also has a cylindrical structure. At this time, the friction protrusion 4 can be detachably arranged in the mounting groove 21 to realize the installation of the friction protrusion 4. Such a setting can also make one side of the friction protrusion 4 protrude compared to the peripheral side surface of the take-up drum 2 to provide friction force. Moreover, through the above setting, the friction protrusion 4 can also be replaced regularly, which is conducive to maintaining a good friction effect for a long time.

[0046] It is understandable that in the actual setting process, the cross-sectional profile of the mounting groove 21 can also be replaced with a square or polygon. Accordingly, the structure of the friction protrusion should be adapted to the opening size and shape of the mounting groove 21 so that the friction protrusion 4 can be stably assembled in the mounting groove 21. No restrictions are imposed on the specific structure of the mounting groove 21 and the friction protrusion 4.

[0047] Reference Figure 2 and Figure 38mm, the steel wire is preferably lifted up by too much force, and the steel wire is not easily slipped.

[0048] Furthermore, in order to increase the friction force exerted on the steel wire, the number of friction protrusions 4 can be multiple, such as three, five or six, and the specific number is not limited here. When setting, multiple friction protrusions 4 are arranged at intervals along the circumference of the take-up reel 2. This can provide friction support at multiple points for the steel wire, making the steel wire less likely to slip and further optimizing and improving the structural stability.

[0049] Furthermore, refer to Figure 3 In order to prevent the steel wire from slipping off the side of the take-up drum 2 during the process of feeding and taking up the wire, limiting steps 22 are respectively provided on the opposite sides of the circumferential surface of the take-up drum 2. The limiting steps 22 are integrally connected to the take-up drum 2, and the limiting steps 22 are arranged in a closed loop along the circumference of the take-up drum 2, so that a positioning recess is formed between the two limiting steps 22; here, the limiting steps 22 can abut against the steel wire for limiting position, and by winding the steel wire in the positioning recess, the effect of limiting the steel wire from falling off the side of the take-up drum 2 is achieved.

[0050] Reference Figure 1 and Figure 4 In order to ensure that the steel wire can be stably pressed onto the take-up drum 2, the belt assembly 3 includes a guide wheel 31, a tensioning wheel 32 and a belt body 33, wherein the guide wheel 31 is rotatably mounted on the base plate 1. The position of the guide wheel 31 relative to the base plate 1 is usually unchanged. Unlike the guide wheel 31, the position of the tensioning wheel 32 relative to the base plate 1 is adjustable when it is set, so that the belt body 33 can be tensioned.

[0051] It can be understood that when installing the tensioning wheel 32, a swing arm 6 can be first rotatably installed on the base plate 1, and a guide screw can be set on the base plate 1. At this time, a spring 5 is fixed between the swing arm 6 and the base plate 1, and the spring 5 is sleeved on the guide screw, and the two ends of the spring 5 are respectively connected to the head of the guide screw and the swing arm 6. The tensioning wheel 32 is rotatably installed on the swing arm 6. At this time, the spring 5 can provide elastic support for the swing arm 6, and the position of the tensioning wheel 32 can be adjusted by elastic force, so that the tensioning wheel 32 can apply elastic force to the belt body 33.

[0052] On this basis, the belt body 33 is simultaneously wrapped with the take-up drum 2, the guide wheel 31 and the tensioning wheel 32. Under the traction of the guide wheel 31 and the tensioning wheel 32, the belt body 33 can rotate along its own trajectory, and when the take-up drum 2 rotates, it can drive the belt body 33 to rotate synchronously, thereby clamping and conveying the steel wire.

[0053] Further, refer to Figure 5 In order to prevent slipping between the belt body 33 and the take-up drum 2, a first protruding tooth 331 is integrally provided on the belt body 33, and a second protruding tooth 23 is provided on the take-up drum 2. In this embodiment, the second protruding tooth 23 is integrally provided on the limiting step 22, and the first protruding tooth 331 is meshed with the second protruding tooth 23. At this time, the first protruding tooth 331 and the second protruding tooth 23 can prevent slipping between the belt body 33 and the take-up drum 2 in the meshing state, and the wire feeding action is more stable.

[0054] Replay Figure 4 In order to drive the take-up drum 2 to rotate, the wire feeding mechanism also includes a driving assembly 7, which includes a driving motor 71 and a driving gear 72. The driving motor 71 is fixedly mounted on the base plate 1, and the driving gear 72 is fixedly mounted on the output shaft of the driving motor 71. At the same time, a plurality of meshing teeth arranged at intervals are integrally provided on the circumference of the take-up drum 2, and the driving gear 72 meshes with the meshing teeth. By starting the driving motor 71, the driving motor 71 can drive the driving gear 72 to rotate, thereby driving the take-up drum 2 to rotate. At this time, the driving motor 71 can adopt a motor element such as a servo motor that can accurately output forward and reverse angles. As the output direction of the torque is changed, the take-up drum 2 can be controlled to realize automatic wire release and wire take-up actions.

[0055] The implementation principle of this embodiment is: by starting the driving component 7, the wire take-up drum 2 can be driven to rotate. At this time, under the action of friction, the belt body 33 in the belt assembly 3 can be synchronously driven to rotate synchronously, thereby making the belt body 33 and the wire take-up drum 2 feed or take up the wire. During the wire feeding process, the friction protrusions 4 located on the side of the wire take-up drum 2 can prevent the wire from slipping and loosening, and the stability of the wire feeding process is optimized and improved.

[0056] So far, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
