Description

Technical Field

[0001] The invention belongs to the technical field of knitting machines, and in particular relates to a knitting machine with a positioning mechanism capable of positioning and stably conveying fabrics. Background Art

[0002] Because fabrics are generally soft, they are difficult to position effectively after the first processing operation on a warp knitting machine. Therefore, after the first crocheting operation, it is difficult to perform a second or subsequent processing operation on the semi-finished fabric. However, due to the ever-changing demand for fabrics, it may be necessary to perform more than one processing operation to meet the needs. For example, to increase the safety of drawstrings on Venetian blinds, some countries have amended laws to require drawstrings to be hidden inside the ladder straps to prevent them from being exposed and easily causing danger to young children.

[0003] However, since the existing warp knitting machines are unable to accommodate the new ladder belt design and provide secondary processing to form a hidden drawcord design on both sides of the existing ladder belt, the existing warp knitting machines are unusable and may need to be redesigned with additional warp knitting machines, resulting in the idleness and waste of existing machines.

[0004] This section is only an example of the ladder strap design of the crocheted blinds requiring secondary processing. In other embodiments, other fabrics may also need to be processed more than twice to increase the variability of the woven fabric.

[0005] In actual use, existing knitting machines still have the disadvantage of being unable to effectively position semi-finished products for secondary processing. Summary of the Invention

[0006] The object of the present invention is to solve the above-mentioned technical problems and provide a knitting machine with a positioning mechanism, which can guide the fabric into the knitting mechanism for secondary construction through the setting of the positioning mechanism, so that the knitting machine can greatly improve the positioning of the secondary crocheting process, thereby increasing the yield rate of the fabric crocheting completion.

[0046] like Figures 1 to 4 As shown, the present invention is a knitting machine with a positioning mechanism for positioning a fabric 10 to be processed. The fabric 10 is, for example, a ladder belt for a Venetian blind. The fabric has a main rope body 11 formed on both sides, and a plurality of auxiliary rope bodies 12 and a plurality of ears 13 are formed at equal intervals between the two main rope bodies 11. The knitting machine includes a knitting machine body 20, a guide mechanism 30, a positioning mechanism 40, and a driving mechanism 50.

[0047] The knitting machine body 20 includes a machine platform 21 . A side frame 210 is formed on both sides of the machine platform 21 . The machine platform 21 is provided with a knitting mechanism 22 .

[0048] The guiding mechanism 30 is disposed between the two side frames 210 and below the knitting mechanism 22 for passively guiding the movement of the fabric 10 .

[0049] The positioning mechanism 40 is disposed between the two side frames 210 and adjacent to the knitting mechanism 22 . The positioning mechanism includes a shaft 41 , a limiting rod 42 , a plurality of guide wheels 43 , a plurality of upper guide plates 44 , and a plurality of lower guide plates 45 .

[0050] The shaft rod 41 and the limiting rod 42 are respectively fixed to the two side frames 210 in parallel.

[0051] The guide wheels 43 are respectively fixed to the shaft 41. The guide wheels 43 are grouped in pairs, and a guide groove 430 is radially recessed on the outer surface of the guide wheels 43. The width of the guide groove 430 is substantially equal to the width of the main rope 11 of the fabric 10. After the fabric 10 is guided out by the guiding mechanism 30, the two main ropes 11 on both sides of the fabric 10 are respectively accommodated in the two guide grooves 430 of the group. The guide wheel 43 is different from the guide groove 430 and has a recessed portion (not shown in the figure) formed on the other side.

[0052] One end of each of the upper guide plates 44 is fixed to the stopper rod 42. The upper guide plates 44 are arranged in pairs, corresponding to the guide wheels 43. The other ends of the upper guide plates 44 abut against the surfaces of the opposing guide wheels 43. The two upper guide plates 44 in each group are located at different locations on the guide grooves 430 of the two guide wheels 43. This allows the two upper guide plates 44 and the two opposing guide wheels 43 to respectively clamp against the ears 13 on both sides of the fabric 10, thereby flattening the ears 13 and preventing warping and unevenness that could affect the yield of subsequent knitting processes. In other embodiments (not shown), the upper guide plates 44 can also be directly mounted on the machine 21, omitting the stopper rods 42.

[0053] One end of each of the lower guide plates 45 is fixed to the knitting mechanism 22. The lower guide plates 45 are arranged in pairs, and the upper guide plates 44, the lower guide plates 45 and the guide wheels 43 correspond to each other. The other ends of the lower guide plates 45 are abutted against the guide wheels 43. The lower guide plates 45 are sequentially formed with a guide portion 450 and a receiving portion 451. The guide portion 450 is adjacent to one end of the knitting mechanism 22 and is close to the opposite side. The corresponding upper guide plate 44 is used for the fabric 10 to be supported on the guide portion 450 and guided out, so that the fabric 10 can be smoothly moved to the knitting mechanism 22 for crocheting processing, and the receiving portion 451 of the lower guide plates 45 forms an arc shape to partially accommodate the recesses of the relative guide wheels 43, thereby appropriately adjusting the position of the lower guide plates 45 to avoid the lower guide plates 45 being too high and interfering with the fabric 10.

[0054] See also Figure 5 and Figure 6 The driving mechanism 50 includes a driving shaft 51, a driven shaft 52, a fixed shaft 53 and a plurality of guide groups 54. The driving mechanism 50 is located below the side of the knitting mechanism 22 away from the positioning mechanism 40. The two ends of the driving shaft 51 are respectively pivoted between the two side frames 210, and the two ends of the driven shaft 52 and the fixed shaft 53 are respectively fixed between the two side frames 210. The driven shaft 52 is located between the driving shaft 51 and the knitting mechanism 22 and is used to adjust the angle at which the fabric 10 is wound around the driving shaft 51. The driving shaft 51 is connected to a power source (not shown in the figure). The fixed shaft 53 is provided in parallel with the adjacent driving shaft 51. The fixed shaft 53 is sleeved with the guide groups 54, and the guide groups 54 are grouped in pairs, and the guide groups 54 respectively have a linkage wheel 540 and a positioning member 541. One side of the linkage wheel 540 is in contact with the drive shaft 51, and the positioning member 541 is provided on the side of the linkage wheel 540 away from the fabric 10 and is adjustably positioned on the fixed shaft 53. When the fabric 10 completes the crocheting operation, it can be rolled up by the drive shaft 51 so that the fabric 10 is linked to the driven shaft 52 and partially bent onto the drive shaft 51. The fabric 10 is then guided out from between the linkage wheel 540 and the drive shaft 51.

[0055] When the knitting machine is performing the crocheting process on the fabric, refer to Figures 1, 2, and 4. In actual use, multiple fabrics 10 can be processed simultaneously according to the needs of the manufacturer. If problems occur during the processing of some of the fabrics 10, adjustments can be made to each fabric 10 or the equipment. For ease of explanation, only one fabric 10 is used as an example to explain in detail as follows:

[0056] The fabric 10 is driven by the driving shaft 51 of the driving mechanism 50, and the fabric 10 is sequentially driven from the guiding mechanism 30 to the positioning mechanism 40 and the knitting mechanism 22, and is then transmitted out by the driving mechanism 50. When the fabric 10 is guided from the guiding mechanism 30 to the positioning mechanism 40, the main ropes 11 on both sides of the fabric 10 are respectively limited in the guide grooves 430 relative to the two guide wheels 43, and the main ropes 11 on the surface of the guide grooves 430 are respectively limited in the guide grooves 430 relative to the two guide wheels 43. The ears 13 on both sides are respectively guided and leveled by the two upper guide plates 44 and move stably toward the knitting mechanism 22. The two main ropes 11 and the ears 13 on both sides of the fabric 10 are supported and guided by the relative lower guide plates 45, and move to the knitting mechanism 22 with a stable and positioning effect, and crocheting operations are performed in the knitting mechanism 22. Since the fabric 10 can move stably, the problem of missed stitches or crocheting failures during knitting by the knitting mechanism 22 can be avoided.

[0057] See also Figure 1 、 Figure 5 and Figure 6When the fabric 10 is crocheted by the knitting mechanism 22, the fabric 10 will be driven to move by the driving shaft 51. The fabric 10 will sequentially move along the driven shaft 52, partially wrap around the driving shaft 51, and be clamped by the driving shaft 51 and the two interlocking wheels 540, and be guided out through the two interlocking wheels 540 to complete the fabric crocheting operation.
