Description

Technical Field

[0001] This invention belongs to the field of textile machinery technology, and relates to a yarn carrier posture adaptive adjustment system and a yarn carrier posture adaptive adjustment method. Background Technology

[0002] In existing 3D knitting machines, the machining accuracy of the yarn carrier cannot fully meet the design dimensions. This results in interference or clearance fits between the yarn carrier and the track, potentially leading to incomplete movement. As the machine continues to move, the accumulated error in the yarn carrier's position can cause it to "jam." Furthermore, the clearance between the yarn carrier and the track causes significant noise and vibration during operation. This not only increases the workload and safety of operators but also necessitates stopping production for inspection and maintenance, which is undoubtedly time-consuming and labor-intensive, severely impacting production efficiency. On the other hand, the current hard-contact sliding friction between the yarn carrier and the track, and between the yarn carriers themselves, also frequently causes movement jams and wear on parts, further exacerbating the "jam" phenomenon. Summary of the Invention

[0003] The purpose of this invention is to provide an adaptive adjustment system for the posture of a yarn carrier, which solves the technical problem in the prior art where the yarn carrier and the track are in hard contact with sliding friction, resulting in frequent movement jamming and wear of parts, causing "locking".

[0004] Another objective of this invention is to provide a method for adaptive adjustment of the posture of a yarn carrier, which has adaptive characteristics and improves the production efficiency of operators.

[0005] The first technical solution adopted in this invention is a yarn carrier posture adaptive adjustment system, including a chassis and a plurality of yarn carriers set on the chassis. Each yarn carrier includes a bottom ball that moves within the chassis. The bottom ball is threadedly connected to a fully threaded stud, which extends out of the chassis. The other end of the fully threaded stud is threadedly connected to a yarn hook. An adaptive mechanism is provided on the fully threaded stud and located between the yarn hook and the chassis for adjusting the posture of the yarn carrier on the chassis.

[0006] The first technical solution of this invention is further characterized by:

[0007] The adaptive mechanism includes a knurled nut threaded onto a fully threaded stud, with an attitude adaptive cup positioned opposite each other at the bottom of the knurled nut and the top of the chassis, and the two attitude adaptive cups are connected by a spring.

[0008] The bottom ball has a threaded blind hole, which is connected to a fully threaded stud.

[0009] The chassis is formed by a series of crisscrossing drag-reducing tracks, which are specifically as follows:

[0010] The drag-reducing track consists of an open section, a first support section, and a second support section from top to bottom along the longitudinal section. The bottom ball is located in the cavity formed by the first and second support sections. The fully threaded stud extends from the open section, and the size of the open section is smaller than the size of the bottom ball. The first support section has an arc-shaped inner wall, which is clearance-fitted with the bottom ball. The axis of the arc-shaped inner wall coincides with the center of the bottom ball. The second support section has a rectangular structure, and the bottom ball makes point contact with the bottom wall of the second support section.

[0011] The bottom ball is made of stainless steel.

[0012] The second technical solution adopted in this invention is a yarn carrier posture adaptive adjustment method, which uses the yarn carrier posture adaptive adjustment system as described above. Specifically, the bottom ball is connected to the fully threaded stud, and then the bottom ball is installed into the drag-reducing track. The posture adaptive cup and spring are sleeved on the fully threaded stud, with one posture adaptive cup in contact with the surface of the drag-reducing track. At this time, a knurled nut is installed. The spring is compressed by the compression between the knurled nut and the other posture adaptive cup. The yarn carrier stops at the cross intersection of the crisscrossing drag-reducing tracks. When the resistance is too great when moving across this position, the spring automatically retracts to achieve the adaptive posture of the yarn carrier.

[0013] The beneficial effects of this invention are:

[0014] This invention utilizes the design of the bottom ball and drag-reducing track of the yarn carrier to achieve rolling friction between them, thereby reducing resistance, minimizing movement jamming and wear on parts, and preventing "lock-up" phenomena. The springs installed in the yarn carrier ensure posture stability and adaptive resistance when passing through track intersections, reducing noise and vibration during operation. All parts of the yarn carrier are standard components, requiring no customization, resulting in a simple, reliable, and highly integrated structure that reduces manufacturing costs and assembly difficulty.

[0019] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1-3 As shown, the yarn carrier posture adaptive adjustment system disclosed in this invention includes a chassis 8 and several yarn carriers disposed on the chassis 8. Each yarn carrier includes a bottom ball 6, which moves within the chassis 8. The bottom ball 6 is threadedly connected to a fully threaded stud 2. A threaded blind hole is opened on the bottom ball 6, which is engaged with the fully threaded stud 2. The fully threaded stud 2 extends out of the chassis 8, and a yarn hook 1 is threadedly connected to the other end of the fully threaded stud 2. The inner hole of the yarn hook 1 is a threaded hole, which is threadedly connected to the fully threaded stud 2. The yarn hook is used as a fiber monofilament bundle yarn hanging connector. An adaptive mechanism is provided on the fully threaded stud 2 and located between the yarn hook 1 and the chassis 8 for adjusting the posture of the yarn carrier on the chassis 8.

[0022] Example 2

[0023] To address the tilting and overturning problem caused by the inability to fix the yarn carrier's posture, a spring and posture-adaptive cups are added to improve the yarn carrier's passability when moving on vertical tracks. When the yarn carrier stops at the intersection of the longitudinal and transverse tracks, excessive resistance occurs when crossing this position during movement. The springs automatically retract to reduce resistance, improving the passability of the yarn carrier on discontinuous tracks and achieving posture self-adaptation. Specifically, based on embodiment 1, the adaptive mechanism includes a knurled nut 3 threaded onto a fully threaded stud 2. Posture-adaptive cups 5 are positioned opposite each other at the bottom of the knurled nut 3 and the top of the base 8, connected by a spring 4. The yarn carrier, equipped with spring 4, can balance the unbalanced forces transmitted from the stainless steel bottom ball 6 in the drag-reducing track 7 in different directions, thus fulfilling the posture self-adaptation requirement of the yarn carrier. The knurled nut 3 rotates by its thread, and its up-and-down movement adjusts the distance between the posture-adaptive cups 5, causing the spring 4 to extend and retract, thereby adjusting the elasticity. The knurling on the knurled nut 3 increases friction, facilitating manual rotation.

[0024] Example 3

[0025] Based on Embodiment 2, the chassis 8 is formed by a plurality of crisscrossing drag-reducing tracks 7, which are specifically as follows:

[0026] like Figure 2The diagram shows a longitudinal cross-sectional view of the drag-reducing track 7. Along the longitudinal section, the drag-reducing track 7 consists of an open section, a first support section, and a second support section from top to bottom. The bottom ball 6 is located within the cavity formed by the first and second support sections. A fully threaded stud 2 extends from the open section, the size of which is smaller than the size of the bottom ball 6 to prevent it from detaching from the drag-reducing track 7. The first support section has an arc-shaped inner wall, which fits the bottom ball 6 with a clearance fit. This not only provides relatively stable guidance for the movement of the bottom ball 6 under the tension of the yarn, but also provides a certain limiting effect for the yarn carrier to stop at the cross-shaped intersection of the drag-reducing tracks 7. The axis of the arc-shaped inner wall coincides with the center of the bottom ball 6. The second support section has a rectangular structure, with the bottom ball 6 in point contact with the bottom wall of the second support section. This mainly prevents dust from accumulating on the arc-shaped inner wall and provides support for the yarn carrier in the non-yarn-loaded state. Furthermore, the point contact between the bottom ball 6 of the yarn carrier and the bottom wall of the drag-reducing track 7 minimizes resistance, thus achieving drag reduction. The track adopts a composite structure of arc and rectangle, which minimizes the motion resistance between the yarn carrier and the drag-reducing track 7. The structure is simple and reduces interference design features, which can effectively reduce the contact area between the yarn carrier and the drag-reducing track 7 and reduce the risk of interference.

[0027] This invention also discloses a method for adaptive adjustment of the yarn carrier's posture. According to the above-mentioned adaptive adjustment system for the yarn carrier's posture, specifically: the bottom ball 6 is connected to the fully threaded stud 2, and then the bottom ball 6 is installed into the drag-reducing track 7. The posture adaptive cup 5 and the spring 4 are sleeved on the fully threaded stud 2, with one posture adaptive cup 5 in contact with the surface of the drag-reducing track 7. At this time, the knurled nut 3 is installed. The spring 4 is compressed by the compression between the knurled nut 3 and the other posture adaptive cup 5. The yarn carrier stops at the cross intersection of the crisscrossing drag-reducing tracks 7. When the resistance is too great when moving across this position, the spring automatically retracts to achieve adaptive posture of the yarn carrier.

[0028] The working process of the yarn carrier posture adaptive adjustment system of the present invention is as follows: During operation, the bottom of the chassis 8 is driven by a motor to a centralized drive device for cross reciprocating linear motion. By indexing the motion cycle of the cross motion pair in the groove of the disc surface, the timing and pause time of the linear reciprocating motion of the motion pair are precisely controlled, realizing the complex conversion process of outputting a single rotary motion into intermittent cross motion of multiple motion pairs.
