[0027] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] like Figures 1-10 As shown, a heald frame movement mechanism for a ribbon weaving machine includes a frame 1, a plurality of heald frames 2, and heald wire pieces 3 fixedly arranged on each heald frame 2. The heald wire pieces 3 have heald eyes 4 through which warp threads can pass. The heald frames 2 are existing technology and will not be described in detail in this solution.

[0030] In this design, the frame 1 is provided with a first rotating shaft 5, a second rotating shaft 15 and a fixed shaft 6. The first rotating shaft 5 and the second rotating shaft 15 are driven to rotate by an external motor and are respectively located on both sides below the fixed shaft 6. The fixed shaft 6 is fixedly installed on the frame 1.

[0031] The first rotating shaft 5 and the second rotating shaft 13 are fixedly installed with eccentric wheels 8, the fixed shaft 6 is rotationally connected with a swing arm 7, the swing arm 7 is the same in number as the heald frames 2, the eccentric wheels 8 on the first rotating shaft 5 and the second rotating shaft 13 are respectively controlled in transmission through the first transmission assembly or the second transmission assembly corresponding to the heald frames 2;

[0032] One end of the swing arm 7 is hingedly connected with the heald frame 2, the heald frame 2 is slidably arranged on the rack 1, when the eccentric wheel 8 rotates, the transmission assembly drives the swing arm 7 to swing, and the heald frame 2 drives the corresponding heald slice 3 to move with the swing arm 7.

[0033] Further, a plurality of eccentric wheels 8 and corresponding transmission assemblies are respectively arranged on each of the first rotating shaft 5 and the second rotating shaft 13, so as to weave corresponding patterns and real objects.

[0034] A plurality of hinged shaft holes 14 are arranged on the swing arm 7 in the direction of different heald frames 2, the multi-shaft hole design supports rapid adjustment of the hinged point, so that the swing arms 7 at different positions can be hingedly connected with the corresponding heald frames 2.

[0035] Specifically, the lever transmission mode of the eccentric wheel 8 driving the swing arm 7 replaces the traditional cam driving, which not only realizes more stable reciprocating movement of the heald frame 2, greatly reduces vibration and noise, and the rolling friction structure also reduces wear and prolongs service life; the modular transmission assembly design is convenient for maintenance and adjustment; the overall structure is more rigid and can withstand high-speed operation, and is particularly suitable for high-efficiency production of zipper tape, satin ribbon and other woven belts.

[0036] The structures of the first transmission assembly and the second transmission assembly are shown in the following embodiments. Embodiment one

[0037] In this embodiment, the first transmission assembly is arranged between the first rotating shaft 5 and the corresponding swing arm 7, the first transmission assembly includes a first connecting rod 9, one end of the first connecting rod 9 is rotationally connected with the outer circumferential surface of the eccentric wheel 8 through a bearing, the other end is hingedly connected with the swing arm 7, and the bearing is connected with the outer circle of the eccentric wheel, which can effectively reduce the friction loss between the eccentric wheel and the connecting rod, so that the heald frame moves more stably and reliably; at the same time, the hinged structure enhances the flexibility of the mechanism, which is convenient for adjustment and maintenance, when the corresponding eccentric wheel 8 rotates, the hinged part of the swing arm 7 and the heald frame 2 circulates between the high position and the low position of the heald frame 2 along with the first connecting rod 9, because the heald frame 2 directly passes through the single-stage connecting rod transmission, the high and low positions of the heald frame 2 change with the up and down changes of the center of the eccentric wheel 8, and the high and low positions circulate regularly, which can stably pass through the weft line at the high and low positions.

[0038] As shown in the accompanying drawings, Figure 3As shown in the attached figure, only one set of first transmission components is shown. However, in this embodiment, multiple sets of first transmission components need to be arranged in parallel on the first rotating shaft 5. The others are not shown. Multiple sets of transmission components and swing arms 7 are installed in parallel to control multiple heald frames 2, thereby increasing the efficiency of the weaving machine. The eccentric wheels 8 corresponding to the different first transmission components connected in parallel are independent and can have different phases to drive the warp threads to be lifted or pressed down, so as to achieve weaving with the weft threads.

[0039] The eccentric wheel-linkage structure in this embodiment can weave a "high-low" pattern. When the heald frame 2 is in a high position, the raised part of the warp thread can pass through the weft thread once. Then the heald frame 2 is pulled down, and the warp thread is driven down by the heald frame 2 to press down on the weft thread. After that, the heald frame 2 moves to a low position, and the weft thread passes through above the warp thread. Finally, the heald frame 2 moves up and presses down on the weft thread, completing one cycle. This ensures that the weft thread can only pass through once when it is in a high or low position in one cycle. After multiple cycles, the weaving is completed, realizing the "high-low" pattern weaving. Example 2

[0040] In this embodiment, the second transmission assembly includes a second connecting rod 10, a rocker arm 11, and a third connecting rod 12. One end of the second connecting rod 10 is rotatably connected to the outer circumferential surface of the eccentric wheel 8 on the second rotating shaft 13 via a bearing, and the other end is hinged to the middle of the rocker arm 11. One end of the rocker arm 11 is hinged to one end of the third connecting rod 12, and the other end of the rocker arm 11 is rotatably mounted on the first rotating shaft 5. It should be noted that, since the rocker arm 11 and the first rotating shaft 5 are rotatably connected by a bearing, the swing of the rocker arm 11 is independent of the rotational speed of the first rotating shaft 5. The third link 12 only supports the rocker arm 11. The other end of the third link 12 is hinged to the swing arm 7. When the eccentric wheel 8 connected to the second link 10 rotates, the swing arm 7 and the heald frame 2 move cyclically between the high and low positions of the heald frame 2 with the third link 12. The ratio of the time the heald frame 2 is in the high position to the time it is in the low position is 1:3. Therefore, the number of times the heald frame 2 passes through the weft yarn when it is in the low position is three times that when it is in the high position. The heald frame 2 passes through the weft yarn three times when it is in the low position, and only once when it is in the high position, thus realizing the weaving pattern corresponding to the "one high and three low" form.

[0041] It should be noted that, as shown in the attached document Figure 9 As shown in (a), (b), (c), and (d), these diagrams represent the positions of the second transmission component and the swing arm 7 corresponding to each 90° rotation of the eccentric wheel 8. The dotted lines in the diagrams are the baselines for determining the high and low positions. During the rotation, the swing arm 7 is in either the high or low position. It can be seen that the time the swing arm 7 is in the low position is three times the time it is in the high position. In this scheme, the second link 10 rotates with the eccentric wheel 8, pushing the rocker arm 11 to swing left and right. Then, it is restricted by the third link 12 to realize the swing arm 7 swinging up and down. Example 3

[0042] In this embodiment, to weave a "two highs and two lows" pattern, a third rotating shaft 15 is also provided on the frame 1. The third rotating shaft 15 is rotatably mounted on the frame 1, as shown in the attached figure. Figure 5 As shown, the third rotating shaft 15 is provided with several eccentric wheels 8. Only one set of the first transmission components is shown in this figure, and the others are not shown. The eccentric wheels 8 on the third rotating shaft 15 are also transmitted to the corresponding swing arms 7 through the first transmission components. The "two high and two low" pattern corresponds to the part of a warp thread that can pass through two weft threads. Then the warp thread is driven down by the heald frame 2 to press down the weft thread. At the same time, multiple sets of heald frames 2 can be set. The raised parts between adjacent warp threads have a phase difference in the left and right directions. Then, a 180° phase difference is set between the eccentric wheels 8 corresponding to the two. The raised part of the warp thread can also pass through two weft threads. By controlling the left and right positions and the phase difference of the eccentric wheels 8, the raised part of the warp thread can pass through a common weft thread, thereby realizing the weaving of the "two high and two low" pattern.

[0043] Furthermore, based on Embodiment 1, when a first rotating shaft 5 and a second rotating shaft 15 are jointly arranged on the frame 1, and the first rotating shaft 5 controls the first transmission component to weave a "one high and one low" pattern and the second rotating shaft 15 drives the second transmission component to weave a "two high and two low" pattern, the speed ratio between the third rotating shaft 15 and the first rotating shaft 5 can be controlled to be 1:2.

[0044] It should be noted that the "one high and one low" eccentric wheel 8 and the first transmission assembly are not limited to those shown in the attached figure. They can be set on the second rotating shaft 15 or on the first rotating shaft 5. Similarly, the "two high and two low" eccentric wheel 8 and the first transmission assembly can be set on another rotating shaft. Example 4

[0045] In this embodiment, a third rotating shaft 15 and a fourth rotating shaft 16 are rotatably connected to the frame 1. Several eccentric wheels 8 are fixedly mounted on the fourth rotating shaft 16. A second transmission assembly is provided between the eccentric wheels 8 on the fourth rotating shaft 16 and the swing arm 7. The rocker arm 11 in the second transmission assembly is rotatably connected to the third rotating shaft 15 through a bearing. By setting the fourth rotating shaft 16, together with the third rotating shaft 15, more second transmission assemblies can be installed on the frame 1, increasing the working efficiency of the equipment. At the same time, the second transmission assembly can be adjusted to be symmetrically arranged relative to the second transmission assembly in Embodiment 2, so that the ratio of the time the heald frame 7 is in the high position to the time it is in the low position is 3:1. Thus, the number of weft threads passed by the heald frame 7 when it is in the high position is three times that when it is in the low position. The rotation speed ratio between the fourth rotating shaft 16 and the second rotating shaft 13 is controlled to be 1:1. Similarly to Embodiment 2, the weave pattern corresponding to the "three highs and one low" pattern is realized.

[0046] It should be noted that, as shown in the attached document Figure 10The (a), (b), (c) and (d) shown in the figure respectively represent the schematic diagram of the second transmission assembly and the position of the swing arm 7 corresponding to each 90° rotation of the eccentric wheel 8, the specific principle is equivalent to the "one high three low" mentioned in the second embodiment, which will not be repeated here. Example five

[0047] In this embodiment, the first rotating shaft 5 and the third rotating shaft 15 are arranged on both sides of the fixed shaft 6, and the second rotating shaft 13 and the fourth rotating shaft 16 are arranged on the side away from the fixed shaft 6 of the first rotating shaft 5 and the third rotating shaft 15. By arranging the first rotating shaft 5 and the second rotating shaft 13 on one side of the fixed shaft 6 and the third rotating shaft 15 and the fourth rotating shaft 16 on the other side, the second transmission assembly is arranged in a symmetrical form, which facilitates the arrangement of the second transmission assembly with the time ratio of 1:3 of the heald frame 2 in the high position and the low position on one side, and the 3:1 on the other side rotating shaft, the arrangement rule, facilitating subsequent maintenance and realizing the corresponding weave patterns of "three high one low" and "one high three low" on one device.

[0048] Furthermore, the first rotating shaft 5 and the second rotating shaft 13 can be provided with the eccentric wheel 8 and the first transmission assembly in combination with the first embodiment and the third embodiment, and by adjusting and controlling the rotating speed of the two rotating shafts, the corresponding weave patterns of "one high one low" and "two high two low" can be realized.

[0049] It should be noted that in the description of the present application, all directional indications (such as up, down, front, back, etc.) are only used to explain the relative position relationship, movement condition, etc. between the components in a certain specific posture (as shown in the drawings), if the specific posture changes, the directional indications will also change accordingly.
