Description

Knitting machine with positioning mechanism

The present invention is applied to the technical field of knitting machines, and in particular to a knitting machine with a positioning mechanism that can position and stably transport fabrics.

Since general fabrics are made of soft materials, it is not easy to effectively position them after the first processing operation on the warp knitting machine. Therefore, after the first crochet operation, it is not easy to perform a second or more processing operation on the semi-finished fabric. However, due to the ever-changing demand for fabrics, it may be necessary to process the fabric more than twice to meet the demand. For example, in response to the safety of the drawstrings of blinds, some countries have amended the law to hide the drawstrings in the ladder straps to prevent the drawstrings from being exposed, which can easily cause children to accidentally get them entangled around their necks and cause danger.

However, the existing warp knitting machines cannot provide secondary processing to accommodate the new ladder belt design, so as to perform secondary processing on both sides of the existing ladder belt to form a hidden drawstring design. As a result, the existing warp knitting machines cannot be used and may need to be redesigned with additional warp knitting machines, resulting in the idleness and waste of existing machines.

This section is just an example of the hook-woven blinds ladder belt design requiring secondary processing, and in other embodiments, it may also be necessary to perform more than two processing operations on other fabrics to increase the variability of the fabric.

The inventor of this invention has found that the conventional knitting machines mentioned above still have the disadvantage of being unable to effectively position semi-finished products for secondary processing in actual use, and has invented this invention to improve the problem.

The main purpose of the present invention is to 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 as to achieve the knitting machine's ability to greatly improve the positioning of the secondary crochet processing, thereby increasing the yield rate of the completed fabric crochet.

The shaft rod 41 and the limit rod 42 are respectively fixed in parallel to the two side frames 210.

The guide wheels 43 are fixed to the shaft 41, and the guide wheels 43 are arranged in pairs. A guide groove 430 is formed radially 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 body 11 of the fabric 10, so that after the fabric 10 is guided out by the guide mechanism 30, the two main rope bodies 11 on both sides of the fabric 10 are respectively accommodated in the two guide grooves 430 of a group. The guide wheel 43 is formed with a concave portion (not shown in the figure) on the other side of the guide groove 430.

One end of the upper guide plates 44 is fixed to the limit rod 42, and the upper guide plates 44 are arranged in pairs and corresponding to the guide wheels 43. The other ends of the upper guide plates 44 are respectively attached to the surfaces of the opposite guide wheels 43. The two upper guide plates 44 in each group are respectively located at different positions of the guide grooves 430 of the two opposite guide wheels 43, so that the two upper guide plates 44 and the two opposite guide wheels 43 can respectively clamp the ears 13 on both sides of the fabric 10 to output the ears 13 smoothly, so as to avoid uneven curling and other effects on the yield of subsequent knitting processing. In addition, in other embodiments, not shown in the figure, the upper guide plates 44 can also be directly set on the machine 21, and the limit rod 42 is omitted.

One end of each of the lower guide plates 45 is fixed to the knitting mechanism 22. The lower guide plates 45 are grouped in pairs, and the upper guide plates 44, the lower guide plates 45 and the guide wheels 43 correspond to each other. The other end of each of the lower guide plates 45 is 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 guide wheel 43. The upper guide plate 44 is provided so that the fabric 10 can be supported by the guide portion 450 and guided out, so that the fabric 10 can be smoothly moved to the knitting mechanism 22 for crochet processing, and the receiving portion 451 of the lower guide plates 45 is formed into an arc shape to partially accommodate the concave portion of the corresponding guide wheels 43, thereby appropriately adjusting the position of the lower guide plates 45 to prevent the lower guide plates 45 from being too high and interfering with the fabric 10.

Please refer to FIG. 5 and FIG. 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 one 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 driven shaft The two ends of the fixed 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 of the fabric 10 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 sleeved with the guide groups 54. 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 driving shaft 51. The positioning member 541 is disposed on one side of the linkage wheel 540 away from the driving wheel group 10 and is adjustable and positioned on the fixed shaft 53. When the fabric 10 completes the crochet processing operation, the fabric 10 can be rolled by the driving shaft 51, so that the fabric 10 is linked to the driven shaft 52 and partially moved on the driving shaft 51. The fabric 10 is then guided out between the linkage wheel 540 and the driving shaft 51.

When the knitting machine performs crochet processing on the fabric, please refer to Figures 1, 2 and 4. In actual use, multiple fabrics 10 can be processed simultaneously according to the needs of the manufacturer. When problems occur during the processing of some of the fabrics 10, adjustments can be made to the individual fabrics 10 or equipment. For the convenience of explanation, only one fabric 10 is used as an example for detailed description as follows:

The fabric 10 is linked to the driving shaft 51 of the driving mechanism 50, and the fabric 10 is driven by the guiding mechanism 30 to the positioning mechanism 40 and the knitting mechanism 22 in sequence, and is transmitted by the driving mechanism 50. When the fabric 10 is guided by the guiding mechanism 30 to the positioning mechanism 40, the main rope bodies 11 on both sides of the fabric 10 are respectively limited in the guide grooves 430 of the two guide wheels 43, and the main rope bodies 11 on the surface of the guide grooves 430 are relatively The ears 13 on both sides are guided by the two upper guide plates 44 to be flat 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 corresponding lower guide plates 45 to move to the knitting mechanism 22 with a stable and positioning effect, and perform crochet operations in the knitting mechanism 22. Since the fabric 10 can move stably, the problem of missing stitches or crochet failures during knitting of the knitting mechanism 22 can be avoided.

Please refer to Figures 1, 5 and 6. When the fabric 10 is knitted by the knitting mechanism 22, the fabric 10 will be driven and moved 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 linkage wheels 540, and guided out by the two linkage wheels 540 to complete the knitting operation of the fabric.
