Description

Technical Field

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

[0002] Computerized flat knitting machines are typically equipped with a base-raising device to provide tension when raising the base of knitted garments. The working principle of the base-raising device is to use a steel wire mechanism with an automatic wire feeding function to provide a stable and reliable base-raising tension for the base yarn, thereby completing the base-raising function of the computerized flat knitting machine. However, the steel wires of existing computerized flat knitting machines are prone to breakage after repeated wire feeding. Often, this is only discovered after the steel wire has completely broken, which requires re-drawing the steel wires on the base plate, resulting in low work efficiency and cumbersome reassembly.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0042] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0043] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0044] As attached Figure 1-8As shown, this utility model embodiment provides a computerized flat knitting machine bottom-raising device for outputting and retrieving steel wire. The computerized flat knitting machine bottom-raising device includes: a drive motor 1, a machine base 2, a drive wheel assembly 3, a wire feeding assembly 4, a wire take-up assembly 5, and a steel wire detection assembly 6. The wire feeding assembly 4 and the wire take-up assembly 5 are both mounted on the machine base 2. The drive motor 1 is mounted on the machine base 2, and the shaft of the drive motor 1 extends into the machine base 2. The drive wheel assembly 3 is located inside the machine base 2 and is driven by the shaft of the drive motor 1. The drive wheel assembly 3 also drives the wire take-up assembly 5 and the wire feeding assembly 4 to rotate. The steel wire detection assembly 6 is distributed between the wire take-up assembly 5 and the wire feeding assembly 4. The steel wire detection assembly 6 includes a detection wheel 60 and a tension sensor 61. The detection wheel 60 is rotatably mounted on the machine base 2 and is used to contact the steel wire. The tension sensor 61 is used to detect the tension change of the steel wire and output the tension information of the steel wire.

[0045] Specifically, the base 2 also includes a housing 20, which covers one side of the base 2 where the drive wheel set 3 is located. The drive motor 1 is fixed to the housing 20, which facilitates the assembly of various components and avoids interference and contamination of the internal gear components. On the other side of the base 2 away from the housing 20, a cavity is formed for mounting the take-up assembly 5, the feed assembly 4, and the wire detection assembly 6. In practical applications, an acrylic plate or similar material can be used to cover the cavity. The wire detection assembly 6, specifically employing a detection wheel 60 and a tension sensor 61, is installed between the take-up assembly 5 and the feed assembly 4. The tension sensor 60 contacts the steel wire to determine the change in the wire's tension, thereby identifying any abnormalities in the wire. The tension sensor 61 is connected to an external control system. If an abnormality occurs in the steel wire, the operator can obtain the relevant information through the control system. This allows the operator to choose to inspect or replace the steel wire without affecting the operation of other equipment. On the one hand, this avoids downtime for the device, and on the other hand, it avoids the situation where the steel wire breaks and is only discovered later, leading to cumbersome replacement of the steel wire. This effectively improves the working efficiency of the computerized flat knitting machine's bottom-raising device and reduces the cumbersomeness of device assembly.

[0046] To facilitate the routing, output, and retrieval of the steel wire, the base 2 is provided with a first guide groove 21 and a second guide groove 22 on both sides of the wire feeding assembly 4. The first guide groove 21 is located near the detection wheel 60, and the second guide groove 22 is located near the opening of the base 2. The central axis of the second guide groove 22 coincides with the central axis of the first guide groove 21. The steel wire, starting from the take-up assembly 5, passes sequentially through the detection wheel 60, the first guide groove 21, the wire feeding assembly 4, and the second guide groove 22, and is finally conveyed out through the opening of the base 2. Specifically, the first guide groove 21... The axis along the length direction can be tangent to or intersect with the detection wheel 60, so that the outer wall of the detection wheel 60 can always be in contact with the steel wire, ensuring that the detection wheel 60 maintains the detection effect on the steel wire. In addition, the detection wheel 60 and the first guide groove 21 play a role in limiting the left and right movement of the steel wire, so that the steel wire can be stably conveyed and retrieved. An anti-bounce limiter can be set at the top of the second guide groove 22 to prevent the steel wire from shaking and popping out of the second guide groove 22. The anti-bounce limiter can be replaced by screws or other parts, and can be implemented by a specific, detachable plate structure.

[0047] See appendix Figure 4 Appendix Figure 5 and attached Figure 6 The take-up assembly 5 includes a take-up disc 50 and a take-up gear 51 coaxially connected to the take-up disc 50; the drive wheel assembly 3 is provided with a first drive gear 31 that meshes with the take-up gear 51. Specifically, both the first drive gear 31 and the take-up gear 51 are covered by the housing 20 to prevent the exposure of transmission components such as gears. The shaft of the drive motor 1 passes through the housing 20 and is fixed coaxially with the first drive gear 31. The drive motor 1 drives the first drive gear 31 to rotate, which in turn drives the take-up gear 51 to rotate, thus achieving the purpose of the take-up reel 50 for wire recovery. It should also be noted that the take-up reel 50 is mounted on the machine base 2 by bearings. The take-up reel 50 and the take-up gear 51 are distributed at both ends of the bearings, so that the gear transmission will not interfere with the take-up and wire feeding processes of the take-up reel 50. In addition, the take-up reel 50 and the machine base 2 are spaced apart and form a movable cavity. The movable cavity can prevent friction between the take-up reel 50 and the machine base 2, ensuring smooth rotation of the take-up reel 50. A take-up ring groove can also be provided on the outer wall of the take-up reel 50 for winding the wire. The starting end of the wire can also be fixed at the top of the take-up reel 50 by screws to prevent the wire from detaching from the take-up reel 50.

[0048] Furthermore, the wire feeding assembly 4 includes a first wire feeding wheel 41 and a second wire feeding wheel 42. A wire feeding section for driving wire feeding is formed between the first wire feeding wheel 41 and the second wire feeding wheel 42. The first wire feeding wheel 41 has a first driven gear 410 coaxially connected, and the second wire feeding wheel 42 has a second driven gear 420 coaxially connected. The first driven gear 410 and the second driven gear 420 mesh with each other. The drive wheel assembly 3 also has a second drive gear 32 coaxially connected to the first drive gear 31. The second drive gear 32 meshes with the second driven gear 420. Specifically, the first drive gear 31 and the second drive gear 32 are coaxially arranged and rotate simultaneously driven by the shaft of the drive motor 1. The first drive gear 31 drives the take-up gear 51 to rotate, and the second drive gear 32 drives the second driven gear 420 to rotate. Also, because the first... Driven gear 410 meshes with second driven gear 420, causing the first wire feeding wheel 41 and the second wire feeding wheel 42 to rotate in opposite directions, thus forming a wire feeding section that stably drives the output and recovery of steel wire. Therefore, this embodiment achieves simultaneous drive of the take-up assembly 5 and the wire feeding assembly 4 via coaxial first driving gear 31 and second driving gear 32, eliminating the need for a clutch structure and using fewer gears to drive different components, resulting in lower production and maintenance costs. It also facilitates the lightweighting and miniaturization of the computerized flat knitting machine's bottom-raising device. Furthermore, it should be noted that both the take-up assembly 5 and the wire feeding assembly 4 in this embodiment contribute power to the recovery and transport of steel wire, a significant difference from traditional equipment where the take-up assembly 5 can only recover steel wire and the wire feeding assembly 4 can only transport steel wire. This makes the recovery and transport of steel wire in this computerized flat knitting machine's bottom-raising device much faster.

[0049] See appendix Figure 4 and attached Figure 7 The wire feeding assembly 4 also includes a gear frame 40. One end of the gear frame 40 is hinged to the base 2, and the other end of the gear frame 40 is provided with a spring 400 connected to the base 2. The middle part of the gear frame 40 is used to install the first wire feeding wheel 41 and the first driven gear 410. Under the action of the spring 400, the first wire feeding wheel 41 can fit with the second wire feeding wheel 42. Specifically, the spring 400 is a tension spring. The elastic gear frame 40 makes the first wire feeding wheel 41 always tend to move closer to fit with the second wire feeding wheel 42, thereby making the steel wire passing through the two subject to greater friction, ensuring that the opposite rotation of the first wire feeding wheel 41 and the second wire feeding wheel 42 can stably drive the feeding and recovery of the steel wire.

[0050] See appendix Figure 3 and attached Figure 4The computerized flat knitting machine's bottom-raising device also includes a stroke detection component 7, which includes a wire feeding position sensor 71, a wire take-up position sensor 72, and a slide bar 70. The machine base 2 is provided with a slide groove 23, one end of which is connected to the movable cavity, and the other end of which is provided with a mounting plate 24. The wire feeding position sensor 71 and the wire take-up position sensor 72 are both fixed on the mounting plate 24, and the wire feeding position sensor 71 and the wire take-up position sensor 72 are distributed sequentially along the length of the slide groove 23. The slide bar 70 is slidably installed in the slide groove 23, and the first end of the slide bar 70 is drivenly connected to the take-up disc 50. The second end of the slide bar 70 is provided with a sensing plate 700, which can be signal-connected to the wire feeding position sensor and the wire take-up position sensor, respectively. Specifically, the bottom of the take-up reel 50 is provided with a spiral groove 501, and the first end of the slide rod 70 is provided with a connecting protrusion 701. The connecting protrusion 701 is inserted into the spiral groove 501, and the rotation of the take-up reel 50 can cause the connecting protrusion 701 to be distributed at different positions in the spiral groove 501. Through the rotation of the take-up reel 50, the connecting protrusion 701 is placed at different positions in the spiral groove 501, which is equivalent to making the first end of the slide rod 70 approach or move away from the rotation center of the take-up reel 50. The slide rod 70 is also guided by the slide groove 23, so that the slide rod 70 can only slide along the length direction of the slide groove 23, and correspondingly, the sensing at the second end of the slide rod 70 is affected. The sensing element 700 is positioned close to the wire feeding position sensor 71 and the wire take-up position sensor 72. Specifically, Hall effect sensors can be used for both position sensors, and the sensing element 700 uses an inductive magnet to detect changes in the position of the slide bar 70. The stroke of the slide bar 70 is determined by the length of the wire wound on the take-up reel 50. Both position sensors are connected to the control system signal, and the position information is used to control the forward or reverse rotation of the drive motor 1 to achieve precise control of wire feeding and take-up. It should also be noted that infrared sensors or other sensors can also be used to acquire the position of the sensing element 700.
