Description

A winding device for a knitting machine Technical Field

[0001] This utility model relates to the field of knitting machine technology, and in particular to a winding device for knitting machines. Background Technology

[0002] The primary function of a knitting machine is to weave various knitted fabrics, including apparel fabrics, decorative fabrics, and industrial fabrics. Through weft knitting, knitting machines can produce a wide variety of knitted fabrics, such as T-shirts, sweatshirts, towels, and other apparel fabrics, as well as industrial and decorative fabrics. The winding device plays a crucial role in a knitting machine; its main function is to guide the yarn from the supply source and wind it onto the knitting machine's winding bobbins.

[0003] Traditional winding devices used in knitting machines have two main shortcomings: firstly, they cannot achieve uniform yarn winding during the winding process, resulting in uneven yarn distribution on the bobbin; secondly, they cannot automatically unload the bobbin. Therefore, it is necessary to optimize and improve traditional winding devices used in knitting machines. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned problems in traditional technology and provide a winding device for knitting machines.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A winding device for a knitting machine includes a mounting plate, a convex frame, a driven member, a servo motor, a drive gear, a slide rail, a slider, a push-pull block, a slotted frame, and mechanical grippers. The convex frame is fixed to the rear side of the mounting plate. The driven member is movably restricted on the mounting plate. The servo motor and the slide rail are mounted on the convex frame. The drive gear is mounted on the output end of the servo motor. The driven member consists of an inner wheel portion movably restricted within the mounting plate and an outer wheel portion located outside the mounting plate. The inner and outer wheel portions share a rectangular through hole for the slotted frame to pass through. The outer circumference of the outer wheel portion is evenly distributed with tooth grooves that mesh with the drive gear. A slider forming a linear guide pair is mounted on the slide rail. A push-pull block is fixed to the outer side of the slider. A rotating head movably restricted within the push-pull block is mounted on the inner end of the slotted frame. A mechanical gripper for clamping the winding bobbin is mounted on the outer end of the slotted frame.

[0007] Furthermore, in the above-mentioned winding device for a knitting machine, the winding bobbin is composed of a hollow roller and side guards on both sides thereof, and the hollow roller and side guards together have a cylindrical cavity.

[0008] Furthermore, in the above-mentioned winding device for a knitting machine, the inner wheel portion of the driven member is composed of a first cylindrical portion and a second cylindrical portion disposed in the middle portion. The thickness of the first cylindrical portion is equal to the thickness of the mounting plate portion, the thickness of the second cylindrical portion is less than the thickness of the mounting plate portion, and the outer diameter of the second cylindrical portion is greater than the outer diameter of the first cylindrical portion.

[0009] Furthermore, in the aforementioned winding device for a knitting machine, the mounting plate has a movable cavity that mates with the inner wheel portion of the driven member.

[0010] Furthermore, in the aforementioned winding device for a knitting machine, the rotating head at the inner end of the slotted frame has a T-shaped structure, and the push-pull block has a T-shaped rotating groove that cooperates with the rotating head.

[0011] Furthermore, in the aforementioned winding device for a knitting machine, the mechanical gripper is provided with two support plates that can move relative to each other. An anti-slip pad is installed on the outer side of the support plate, and the outer end of the anti-slip pad is provided with an arc-shaped surface that facilitates cooperation with the cylindrical cavity in the winding drum.

[0012] The beneficial effects of this utility model are:

[0013] This utility model's winding device is rationally designed, mainly consisting of a mounting plate, a convex frame, a driven component, a servo motor, a driving gear, a slide rail, a slider, a push-pull block, a slotted frame, and mechanical grippers. The servo motor, driving gear, and driven component together constitute the winding rotation drive assembly, while the slide rail, slider, push-pull block, and slotted frame together constitute the winding axial displacement assembly. The winding rotation drive assembly drives the mechanical grippers and the winding drum they hold to rotate. The winding axial displacement assembly drives the mechanical grippers and the winding drum to linear displacement. In this way, while the winding drum rotates and winds the yarn, it also undergoes axial displacement, allowing the winding position of the drum to be adjusted automatically, thus achieving uniform winding. After winding is complete and the yarn is cut, simply releasing the mechanical grippers from the winding drum and retracting them automatically unloads the winding drum.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0025] As shown in Figures 1-6, this embodiment provides a winding device for a knitting machine, including a mounting plate 1, a convex frame 2, a driven member 3, a servo motor 4, a driving gear 5, a slide rail 6, a slider 7, a push-pull block 8, a slotted frame 9, and a mechanical gripper 10. A convex frame 2 is fixed to the rear side of the mounting plate 1. The driven member 3 is movably restricted on the mounting plate 1. The servo motor 4 and the slide rail 6 are mounted on the convex frame 2. The driving gear 5 is mounted on the output end of the servo motor 4. The driven member 3 consists of an inner wheel portion 301 movably restricted within the mounting plate 1 and an outer wheel portion 302 located outside the mounting plate 1. The inner wheel portion 301 and the outer wheel portion 302 share a rectangular through hole 303 to facilitate the passage of the slotted frame 9. The outer circumference of the outer wheel portion 302 is evenly distributed with toothed grooves 304 that mesh with the driving gear 5. A slider 7, forming a linear guide pair with the slide rail 6, is mounted on the slide rail 6. A push-pull block 8 is fixed to the outer side of the slider 7. The inner end of the slotted frame 9 is equipped with a rotating head that is restricted to movement in the push-pull block 8, and the outer end of the slotted frame 9 is equipped with a mechanical gripper 10 for clamping the winding spool 11.

[0026] In this embodiment, the winding drum 11 is composed of a hollow roller 111 and side flanges 112 on both sides thereon, and the hollow roller 111 and the side flanges 112 together have a cylindrical cavity 113.

[0027] In this embodiment, the inner wheel portion 301 of the driven member 3 is composed of a first cylindrical portion and a second cylindrical portion disposed in the middle portion. The thickness of the first cylindrical portion is equal to the thickness of the portion of the mounting plate 1 where it is located, the thickness of the second cylindrical portion is less than the thickness of the portion of the mounting plate 1 where it is located, and the outer diameter of the second cylindrical portion is greater than the outer diameter of the first cylindrical portion.

[0028] In this embodiment, the mounting plate 1 has a movable cavity that cooperates with the inner wheel portion 301 in the driven member 3.

[0029] In this embodiment, the rotating head at the inner end of the slot frame 9 has a T-shaped structure, and the push-pull block 8 has a T-shaped rotating groove that cooperates with the rotating head.

[0030] In this embodiment, the mechanical gripper 10 is provided with two support plates that can move relative to each other.
