Description
Technical Field
[0001] This utility model relates to the technical field of conveying and locking of computerized flat knitting machines, and in particular to a locking mechanism for a single-sided computerized flat knitting machine. Background Technology
[0002] Computerized flat knitting machines are mainly used for automated production of knitted products. During the conveying process, active conveying rollers and locking rollers are used to transport the knitted products. The knitting machines need to be adjusted according to the different thicknesses of the knitted products.
[0003] Publication No. CN215856627U discloses a locking mechanism for intelligent flat knitting machines. It includes a locking shaft mounted on a frame via bearings. One end of the locking shaft is connected to a locking turntable. A locking block is positioned above the locking turntable and hinged to the frame via a pin. A cover is positioned above the locking block, and a compression spring is located inside the cover. One end of the compression spring is connected to the inner wall of the cover, and the other end is connected to the upper side of an adjustable connecting block. Several adjustable connecting blocks are mounted on the locking shaft, and a locking rod is connected to each adjustable connecting block. The other end of the locking rod is connected to a locking roller, which engages with the drive conveyor roller for transmission. This device uses a check disc to lock the locking blocks and prevent reverse opening, increasing the fabric conveying locking force of the flat knitting machine, preventing slippage between the conveyor roller and the locking roller, avoiding fabric accumulation at the outlet and hindering smooth delivery, thus improving fabric quality and processing speed. Furthermore, the locking force can be adjusted according to the fabric thickness, making it suitable for outputting fabrics of different thicknesses.
[0004] The aforementioned application can prevent slippage between the conveyor roller and the locking roller during use, thus avoiding the accumulation of fabric at the outlet and preventing it from being delivered smoothly. However, the application requires the adjustment of multiple bolts and the operation handle, which makes the operation more cumbersome and increases the cost of use. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a locking mechanism for a single-sided computerized flat knitting machine, so as to solve the technical problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0016] In summary, this utility model has at least one of the following beneficial technical effects:
[0017] 1. The locking mechanism of this single-sided computer flat knitting machine can be used by directly pulling the handle to drive the positioning shaft to make a circular motion, which in turn drives the entire locking roller to make a circular motion. When the locking roller moves, the distance between the locking roller and the driving roller can be adjusted to lock the transport of knitted fabrics of different thicknesses. This achieves the effect of simple and compact structure and reduced use cost.
[0018] 2.

Detailed Implementation
[0026] The present invention will be further described in detail below with reference to the accompanying drawings.
[0027] Example:
[0028] Reference Figures 1-4The present invention discloses a locking mechanism for a single-sided computer flat knitting machine, comprising a bracket 1, a support shaft 2 rotatably connected inside the bracket 1, and an active roller 3 connected to the outer periphery of the support shaft 2;
[0029] Arc-shaped grooves 4 are provided on opposite sides of the bracket 1, and the arc-shaped grooves 4 gradually move away from the active roller 3 from top to bottom. A support rod 6 is slidably connected in the arc-shaped groove 4. A positioning shaft 7 is connected between the end sides of the two support rods 6. A locking roller 8 is connected between the two positioning shafts 7. The outer periphery of the locking roller 8 is in contact with the outer periphery of the active roller 3.
[0030] A limiting member 9 is provided on the outer periphery of the support shaft 2 to limit the support rod 6, and a control member 22 is provided on the side of the bracket 1 to control the position of the locking roller 8.
[0031] In this embodiment, reference Figure 1 The control element 22 is manually operated. (Refer to...) Figure 3 The control component 22 will drive the support rod 6 to slide in the arc groove 4. While the support rod 6 slides in the arc groove 4, it will also drive the positioning shaft 7 to move synchronously, so that the positioning shaft 7 moves with the support rod. The arc groove 4 is set to gradually move away from the drive roller 3 from top to bottom. Therefore, when the support rod 6 slides in the arc groove 4, it will drive the locking roller 8 to gradually move away from the drive roller 3, so that the distance between the locking roller 8 and the drive roller 3 increases. At this time, the product woven by the flat knitting machine can pass through the drive roller 3 and the locking roller 8. Then, the control component 22 drives the locking roller 8 to slide upward again, so that the knitted product is clamped by the locking roller 8 and the drive roller 3, and then clamped by the limiting component 9.
[0032] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the limiting member 9 includes a limiting block 10, which is connected to the inner wall of the bracket 1, and a ratchet 11 is provided on the outer periphery of the limiting block 10;
[0033] The end of the support rod 6 is provided with a recessed hole 12, and a torsion spring 13 is connected in the recessed hole 12. The end of the torsion spring 13 is connected with a pawl 14, and the end of the pawl 14 is inserted into the ratchet groove 11. A reset member 18 is connected to the side of the support rod 6 away from the locking roller 8.
[0034] In this embodiment, reference Figure 3 The limited block 10 and Figure 4When the support rod 6 slides, it will drive the pawl 14 to slide synchronously. The pawl 14 will be abutted by the side wall of the ratchet groove 11, and then the pawl 14 will be rotated by the base between the ratchet groove 11 and the pawl 14. When the pawl 14 moves to the lower side wall of the ratchet groove 11, it will be driven by the torsion spring 13, and then the pawl 14 will abut against the inner side wall of the ratchet groove 11 again.
[0035] When the locking roller 8 needs to slide upward, the restriction between the pawl 14 and the ratchet groove 11 can be released by the reset member 18. After the locking roller 8 and the driving roller 3 clamp and lock the knitted product, the reset member 18 can be released so that the pawl 14 can re-restrict the support rod 6 with the ratchet groove 11.
[0036] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the control component 22 includes a control shaft 15, which is rotatably connected to the outer side of the bracket 1. A handle 16 is connected to the outer periphery of the control shaft 15. A groove 17 is provided on the side of the handle 16 near the bracket 1. The end of the support rod 6 away from the locking roller 8 extends into the groove 17 and is slidably connected to the groove 17.
[0037] In this embodiment, reference Figure 1 The control shaft 15 is rotatably connected to the side of the bracket 1. Manually rotating the handle 16 will cause the support rod 6, which extends into the slide groove 17, to slide in the arc groove 4, thereby facilitating the movement of the positioning shaft 7 and the locking roller 8. This allows for quick adjustment of the distance between the locking roller 8 and the active roller 3, enabling the knitted fabric to be quickly locked and facilitated for transportation.
[0038] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the reset member 18 includes a torsion bar 19, which is rotatably connected to the side of the handle 16. The torsion bar 19 passes through the handle 16 and extends into the recess 12. The end of the torsion bar 19 is connected to the pawl 14, and a knob 20 is connected to the end of the torsion bar 19 away from the handle 16.
[0039] The handle 16 has a clearance groove 21 on its side for avoiding the torsion bar 19.
[0040] In this embodiment, reference Figure 4 The torsion bar 19 is rotatably connected to the side of the handle 16. When it is necessary to release the constraint between the pawl 14 and the ratchet groove 11, the handle 16 is twisted, causing the handle 16 to move the pawl 14. (See reference...) Figure 3Move the pawl 14 until it is disengaged from the ratchet groove 11, allowing it to rotate counterclockwise. Then rotate the knob 20, causing the torsion bar 19 to rotate. The torsion bar 19 then causes the pawl 14 to completely disengage from the ratchet groove 11. (Refer to...) Figure 4 At this point, the handle 16 can be pulled, which will eventually drive the locking roller 8 to work with the active roller 3 to lock the knitted product.
[0041] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 4 As shown, the limiting block 10 is arranged in the shape of a magatama, and its outer side gradually moves away from the support shaft 2 from top to bottom.
[0042] In this embodiment, reference Figure 3 The limiting block 10, in particular, has an outer edge that gradually moves away from the support shaft 2 from top to bottom. Therefore, referring to... Figure 4 When the handle 16 is turned, the pawl 14 moves, allowing it to follow the trajectory of the arc groove 4. The trajectory of the arc groove 4 is the same as the trajectory of the outer side of the limiting block 10. Therefore, the pawl 14 can always cooperate with the ratchet groove 11, preventing the pawl 14 from completely disengaging from the ratchet groove 11 during movement, which would affect the limiting of the locking roller 8.
[0043] The implementation principle of the above embodiment is as follows: Manually rotating the handle 16 will cause the support rod 6 extending into the slide groove 17 to slide in the arc groove 4. While the support rod 6 slides in the arc groove 4, it will also drive the positioning shaft 7 to move synchronously, so that the positioning shaft 7 moves with the support rod. The arc groove 4 is set to gradually move away from the active roller 3 from top to bottom. Therefore, when the support rod 6 slides in the arc groove 4, it will drive the locking roller 8 to gradually move away from the active roller 3, so that the distance between the locking roller 8 and the active roller 3 increases. At this time, the product woven by the flat knitting machine can pass between the active roller 3 and the locking roller 8. Then, by manually rotating the handle 16 again, the locking roller 8 is driven to slide upward, so that the knitted product is clamped by the locking roller 8 and the active roller 3, and then clamped by the limiting member 9.
[0044] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
