Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a computerized flat knitting machine suitable for a biaxial knitting method with warp and weft pads. Background Technology

[0002] When a computerized flat knitting machine is used for biaxial knitting structures with warp and weft, the warp yarn needs to be vertically positioned in the center of the fabric and interwoven with the weft and knitting yarns on both sides. The introduction of the warp yarn is particularly important. However, the front and rear cam sets are fixed together by a connecting component (bridge). During knitting, the front and rear cam sets, along with the connecting component, need to move back and forth. Since the connecting component of the front and rear cam sets spans above the yarn guide, the warp yarn obviously cannot be directly introduced vertically above the yarn guide; that is, the warp yarn cannot pass vertically through the guide hole from the front. To solve this problem, in existing technology, the warp yarn is introduced laterally from both ends of the flat knitting machine and then bends at approximately 90° to enter the vertical yarn guide. This leads to increased frictional resistance of the warp yarn during tensioning, making the guide mechanism heavy and causing deformation of the guide rails. At the same time, the warp, weft, and knitting yarn are introduced in the same lateral section, sharing limited space, which easily causes multiple yarns to become tangled and intertwined, affecting the efficiency of mass production knitting. Utility Model Content

[0003] The purpose of this invention is to provide a computerized flat knitting machine that allows the warp yarn to be vertically introduced into the toothed opening, reducing friction during warp yarn introduction and preventing various yarns from intertwining during introduction.

[0004] To achieve the above-mentioned technical objectives, the technical solution of this utility model is as follows:

[0005] A computerized flat knitting machine includes a frame, a front needle bed and a rear needle bed symmetrically arranged on the frame. A front cam seat is mounted on the front needle bed, and a rear cam seat is mounted on the rear needle bed. The front and rear cam seats are independent of each other. The front cam seat moves on the front needle bed via a first front guide rail and a second front guide rail. The first front guide rail is located below the front cam seat, and the second front guide rail is located above it. The front cam seat and the second front guide rail are connected by a front guide rail bracket. The rear cam seat moves on the rear needle bed via a first rear rear guide rail and a second rear rear guide rail. The first rear guide rail is located below the rear cam seat, and the second rear guide rail is located above it. The rear cam seat and the second rear rear guide rail are connected by a rear guide rail bracket. A gap exists between the front and rear guide rail brackets, located above the teeth of the front and rear needle beds. This gap allows warp threads to pass through and enter the teeth of the front and rear needle beds.

[0006] Furthermore, the front second guide rail and the rear second guide rail are mounted on the frame via columns.

[0007] Furthermore, a reinforcing rod (bar or beam) is connected to the column, and a yarn guide rail is provided below the reinforcing rod (bar or beam). The yarn guide rail is connected to the reinforcing rod (bar or beam) through a connector.

[0008] Furthermore, a platform is provided above the front and rear triangular seats, and the front second guide rail and the rear second guide rail are provided at the bottom of the platform.

[0009] Furthermore, the table surface is provided with several rows of threading holes, which are located above the front needle bed and the rear needle bed teeth.

[0010] Furthermore, a yarn guide rail is provided below the table surface, and the yarn guide rail is connected to the table surface via a connector.

[0011] To achieve synchronous movement of the front and rear triangular seats, a power shaft is installed on the frame, and a power unit drives the power shaft to rotate. A front drive wheel and a rear drive wheel are installed on the power shaft. The front drive wheel is connected to the front driven wheel through a front transmission belt, and the front triangular seat is connected to the front transmission belt. The rear drive wheel is connected to the rear driven wheel through a rear transmission belt, and the rear triangular seat is connected to the rear transmission belt. The front transmission belt drives the front triangular seat to move, and the rear transmission belt drives the rear triangular seat to move.

[0012] As another method to allow the warp yarn to be vertically introduced into the needle teeth, a computerized flat knitting machine includes a frame, a front needle bed and a rear needle bed symmetrically arranged on the frame. A front cam seat is provided on the front needle bed, and a rear cam seat is provided on the rear needle bed. The front cam seat and the rear cam seat are independent of each other. The front cam seat moves on the front needle bed via a first front guide rail and a second front guide rail. The first front guide rail is located below the front cam seat, and the second front guide rail is located above the front cam seat. The rear cam seat moves on the rear needle bed via a first rear rear guide rail and a second rear rear guide rail. The first rear rear guide rail is located below the rear cam seat, and the second rear rear guide rail is located above the rear cam seat.

[0013] This invention eliminates the connecting components (such as a bridge) between the front and rear triangular seats, and separates the front and rear triangular seats of the knitting machine head, making them structurally independent. This allows the warp yarn to be guided from top to bottom in a vertical direction, avoiding interference and obstruction when the connecting components of the front and rear triangular seats move left and right. The warp yarn is guided from top to bottom in a vertical direction, reducing friction during guidance and preventing the various yarns from becoming tangled and intertwined during guidance. The yarn guide rail is connected to the table or reinforcing rod (bar or beam) through a connector, making the yarn guide rail less prone to deformation under stress. Attached Figure Description

[0018] Example 1

[0019] like Figure 1 , 2 As shown, a computerized flat knitting machine includes a frame and a front needle bed 8 and a rear needle bed 8' symmetrically arranged on the frame. A front cam seat 11 is provided on the front needle bed 8, and a rear cam seat 11' is provided on the rear needle bed 8'. The front cam seat 11 and the rear cam seat 11' are independent of each other, and a table 2 is provided above the front cam seat 11 and the rear cam seat 11'. Specifically, the front triangular seat 11 moves on the front needle bed 8 via the front first guide rail 81 and the front second guide rail 7. The front first guide rail 81 is located on the lower side of the front triangular seat 11, and the front second guide rail 7 is connected to the bottom of the platform 2 above the front triangular seat 11. The front triangular seat 11 and the front second guide rail 7 are connected by the front guide rail bracket 6. The rear triangular seat 11' moves on the rear needle bed 8' via the rear first guide rail 81' and the rear second guide rail 7'. The rear first guide rail 81' is located on the lower side of the rear triangular seat 11', and the rear second guide rail 7' is connected to the bottom of the platform 2 above the rear triangular seat 11'. The rear triangular seat 11' and the rear second guide rail 7' are connected by the rear guide rail bracket 6'. There is a gap between the front guide rail bracket 6 and the rear guide rail bracket 6'. The gap is located above the teeth of the front needle bed 8 and the rear needle bed 8'. This gap is used for the warp thread 1 to pass through and enter the teeth of the front needle bed 8 and the rear needle bed 8'.

[0020] The platform 2 is located on a reinforcing rod (bar or beam), which connects the front column 13 and the rear column 13'. The front second guide rail 7 and the rear second guide rail 7' are connected to the bottom of the platform 2. In order to realize the reciprocating movement of the triangular seat along the second guide rail, a sliding mechanism needs to be provided between the triangular seat and the second guide rail. The sliding mechanism can adopt a sliding or rolling mechanism commonly used in the prior art. For example, the top of the front guide rail bracket 6 is provided with a groove (or roller mechanism), and the front second guide rail 7 is located in the groove (or roller mechanism). When the front triangular seat 11 moves, the groove (or roller mechanism) moves along the front second guide rail 7. Similarly, the sliding mechanism (or rolling mechanism) on the top of the rear guide rail bracket 6' can also be the same as that on the front guide rail bracket 6. Of course, the top of the front guide rail bracket 6 is provided with a slider or roller, and the front second guide rail 7 is provided with a groove. The slider (or roller) is located in the groove. When the front triangular seat 11 moves, the slider (or roller) moves along the groove on the front second guide rail 7. Similarly, the sliding mechanism (or rolling mechanism) on the top of the rear guide rail bracket 6 can also be the same as that on the front guide rail bracket 6.

[0021] The table surface 2 has several rows of threading holes 3, which are located above the teeth of the front needle bed 8 and the rear needle bed 8', so that the warp threads 1 can be guided vertically from top to bottom into the teeth of the front needle bed 8 and the rear needle bed 8'. Of course, the threading holes 3 can also be formed by gaps in the table surface. For example, the table surface includes a front panel and a back panel, with a gap reserved between the front panel and the back panel for the warp threads to pass through.

[0022] A yarn guide rail 12 is installed below the platform 2. The yarn guide rail 12 is connected to the platform 2 via a connector 14. Alternatively, the yarn guide rail 12 can also be connected to a reinforcing rod (bar or beam) via the connector 14. The connector 14 is located within the gap between the front guide rail bracket 6 and the rear guide rail bracket 6', i.e., the front guide rail bracket 6 and the rear guide rail bracket 6' are located on the front and rear sides of the connector 14, respectively. Of course, to improve the rigidity of the yarn guide rail 12, multiple connectors 14 can be installed between the yarn guide rail 12 and the platform 2.

[0023] A warp yarn guide is installed on the yarn guide rail 12, located above the teeth of the front needle bed 8 and the rear needle bed 8'. The warp yarn guide includes several yarn inlet holes 4 arranged sequentially at equal intervals. A yarn guide needle 5 is correspondingly provided below each yarn inlet hole 4. The lower end of the yarn guide needle 5 has a yarn outlet hole, which is located between the teeth of the front needle bed 8 and the rear needle bed 8'. The warp yarn 1 is distributed vertically through the yarn inlet holes 4 and the yarn outlet holes. In use, multiple warp yarns are respectively inserted into different yarn inlet holes 4, and then passed through the yarn outlet hole at the end of the corresponding yarn guide needle 5 below the yarn inlet hole 4, and guided into the space between the teeth of the front needle bed 8 and the rear needle bed 8'; that is, after a warp yarn 1 is inserted through a yarn inlet hole 4, it is then passed through the corresponding yarn outlet hole below the yarn inlet hole and guided into the space between the teeth of the front needle bed 8 and the rear needle bed 8'.

[0024] To achieve synchronous movement of the front and rear triangular seats, a power shaft 10 is installed on the machine frame on the left side (or right side). The power shaft 10 is connected to a power device, which is a servo motor, to drive its rotation. A front drive wheel 101 and a rear drive wheel 101' are installed on the power shaft 10. The front drive wheel 101 is located outside the front needle bed 8. A front driven wheel is also installed outside the front needle bed 8, located on the right side of the front needle bed 8. The front driven wheel is connected to the front drive wheel 101 via a front drive belt. The front triangular seat 11 is connected to the front drive belt, which drives the front triangular seat 11 to move. The rear drive wheel... 101' is located outside the rear needle bed 8'. A rear driven wheel is also provided outside the rear needle bed 8'. The rear driven wheel is located on the right side of the front needle bed 8'. The rear driven wheel is connected to the rear driving wheel 101' through the rear transmission belt. The rear triangular seat 11' is connected to the rear transmission belt. The rear transmission belt drives the rear triangular seat 11' to move. The motor drives the power shaft 10 to rotate. The front transmission belt drives the front triangular seat 11 to move along the front second guide rail 7 and the front first guide rail 81 on the front needle bed 8. The rear transmission belt drives the rear triangular seat 11' to move along the rear second guide rail 7 and the rear first guide rail 81' on the rear needle bed 8', realizing the synchronous movement of the front and rear triangular seats.

[0025] This embodiment eliminates the connecting bridge (connecting component) between the front and rear triangular seats, and separates the front and rear triangular seats of the knitting machine head, making them structurally independent. This allows the warp yarn 1 to be guided from top to bottom in a vertical direction, reducing friction during guidance and minimizing the tangling and intertwining of various yarns during guidance. The yarn guide rail 12 is connected to the table 2 or a reinforcing rod (bar or beam) via a connector 14, eliminating potential deformation problems of the yarn guide rail 12.

[0026] Of course, as another embodiment, the front second guide rail 7 can also be set on the front column 13, and the front triangular seat 11 and the front second guide rail 7 are connected by the front guide rail bracket 6. The rear second guide rail 7' can also be set on the rear column 13', and the rear triangular seat 11' and the rear second guide rail 7' are connected by the rear guide rail bracket 6'.

[0027] Example 2

[0028] The difference from Embodiment 1 is that the front second guide rail 9 is set on the front needle bed 8 and located on the upper side of the front triangular seat 11. The front triangular seat 11 moves along the front second guide rail 9 and the front first guide rail 81 on the front needle bed 8. The rear second guide rail 9' is set on the rear needle bed 8' and located on the upper side of the rear triangular seat 11'. The rear triangular seat 11' moves along the rear second guide rail 9' and the rear first guide rail 81' on the rear needle bed 8'.

[0029] Of course, the second guide rails 7 and 7' in Embodiment 1 and the second guide rails 9 and 9' in Embodiment 2 can also be installed and used simultaneously.

[0030] like Figure 3As shown in the above embodiment, since the front and rear triangle seat connecting components are discarded, the communication control lines of the front and rear triangle seats also need to be changed: the main controller outputs to the machine head unit respectively, that is, the front and rear parts are independent controllers. The controllers of the front half of the needle bed (including triangle system controllers 16, 16' and yarn guide switching mechanism controllers 15, 15', the same below) and the controllers of the rear half of the needle bed can be respectively installed on the front guide rail bracket 6 and the rear guide rail bracket 6', and are respectively connected to the main controller through aviation line interfaces 17, 17'.

[0031] The above embodiments do not limit the present invention in any way. All technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
