Description

Technical Field

[0001] This utility model relates to the field of ribbon weaving machine equipment, specifically a lifting weft frame suitable for ribbon weaving machines. Background Technology

[0002] In recent years, with the rapid development of the ribbon industry, raw material suppliers have been making increasingly larger weft yarn bobbins and heavier weft yarns to meet the demands of efficient mass production. Traditional weft yarn racks, due to space limitations, can only be installed at the rear and upper part of the ribbon weaving machine, typically at a height of over 2 meters. When operators are changing weft yarn, if they stand and reach upwards to retrieve it, the heavy bobbins can easily fall and injure the worker. Therefore, they often first bring in an 80-centimeter-high wooden stool. They then change the weft yarn by climbing up and down the stool. However, this also carries risks; if the stool sways during the process, there is a risk of falling. Therefore, this method of working at height greatly increases the workload and accident risk for operators. Existing support frames for holding weft yarn bobbins are all made of square tubing connected together, and their height cannot be adjusted. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a lifting weft frame suitable for ribbon weaving machines, reducing the difficulty of installing and disassembling the weft bobbin.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A lifting weft frame for a ribbon weaving machine includes a support frame, a head frame is mounted on the upper part of the support frame, a height adjustment mechanism is installed on the head frame, the height adjustment mechanism is connected to a support rod, the support rod is located in the lower area of ​​the head frame, the support rod is provided with a weft disc for placing yarn bobbins, and the height adjustment mechanism drives the support rod to move up and down.

[0006] As a further improvement, a support rod is provided on each of the symmetrical sides of the pan head frame, and a height adjustment mechanism is provided at each of the four corners of the pan head frame. A height adjustment mechanism is connected to each end of a support rod.

[0007] As a further improvement, the height adjustment mechanism includes an electric push rod suspended from the pan head frame, and the output rod of the electric push rod is fixed with a mounting block, which is locked to the support rod by screws.

[0010] As a further improvement, the head frame is equipped with a weft guide rod.

[0011] As a further improvement, the edge of the head frame is provided with a tensioner.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] Using an electric push rod, the support rod for installing the weft yarn spool moves up and down, thereby realizing the up and down movement of the weft yarn spool. When installing and removing the weft yarn spool, only the height of the weft yarn spool is needed. Operators do not need to use other workers to raise it, which improves the safety of operation and reduces the difficulty of operation. Attached Figure Description

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] In the description of this invention, it should be understood that if terms such as "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can refer to a mechanical connection or an electrical connection. They can refer to a direct connection or an indirect connection through an intermediate medium, and they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0020] like Figure 1 As shown, a lifting weft frame suitable for a ribbon weaving machine includes a support frame 13. A head frame 8 is mounted on the upper part of the support frame 13. A height adjustment mechanism is installed on the head frame 8, and a support rod 12 is connected to this mechanism. The support rod 12 is located in the lower area of ​​the head frame 8, and a weft disc 10 for placing yarn bobbins is provided on the support rod 12. The height adjustment mechanism drives the support rod 12 to move up and down. One side of the support frame 13 overlaps with the ribbon weaving machine 1, and the yarn from the yarn bobbins on the weft disc 10 is drawn out into the ribbon weaving machine. Using the height adjustment mechanism, when assembling or disassembling yarn bobbins, the support rod lowers, and the weft disc lowers synchronously. Operators can install or disassemble yarn bobbins without the need for other elevating tools, reducing the difficulty of operation.

[0021] Because the support rod can move up and down, the weft coil, which is fixed at a fixed height, can be transformed into a structure whose height can be adjusted at any time, thereby reducing the difficulty of installing the yarn bobbin.

[0022] The headstock frame 8 has a support rod 12 symmetrically arranged on each side, and a height adjustment mechanism is installed at each of the four corners of the headstock frame 8. Each support rod is connected to a height adjustment mechanism at both ends. The height adjustment mechanisms at both ends of the support rods work together to raise or lower them, resulting in smoother movement and preventing the yarn bobbins placed on the weft reel from shaking or falling off during vertical movement. The two support rods are controlled independently, and the two height adjustment mechanisms on the same support rod operate synchronously, ensuring that the support rod does not tilt during vertical movement, thus preventing the yarn bobbins from slipping off.

[0023] The height adjustment mechanism includes an electric actuator 5, which is suspended from the headstock 8. The output rod of the electric actuator is fixed to a mounting block, which is secured to the support rod with screws. The output rod of the electric actuator 5 extends downwards, facilitating the vertical movement of the support rod 12. A suitable electric actuator model can be selected based on the overall height to meet the required extension length.

[0024] The pan head frame 8 includes crisscrossing tubing, such as square tubes and profiles, which are fixed by welding.

[0025] The bottom surface of the support frame 13 is equipped with load-bearing legs to ensure stable placement.

[0026] In addition, the head frame 8 is equipped with a weft guide rod 6 for guiding the weft yarn.

[0027] The edge of the head frame 8 is equipped with a tensioner 4 to control the tension of the yarn transmission.

[0028] This utility model is used in conjunction with a ribbon weaving machine and is assembled on one side of the ribbon weaving machine.

[0029] In practical use: The electric push rod moves the support rod downwards to a suitable height, allowing the operator to place the weft yarn bobbin on the weft reel while standing on the ground, or remove the used bobbin and replace it with a new one. Then, the electric push rod raises the support rod to the working height. After the weft yarn emerges from the bobbin, it passes through the tensioner 4 via the weft guide rod 6, forming the yarn path 3, and then passes around the weft guide rod 6 to enter the weft adjuster on the machine. Alternatively, a new weft yarn 11 can be pre-placed on the ground, with the joint tied to the tail of the weft yarn 7 to be unwound on the weft yarn frame. This way, after the weft yarn 7 is unwound, the machine can be continuously connected to a new weft yarn without stopping. Finally, the weft yarn tray is lowered, supporting the bottom of the new weft yarn, and placed on top. This simplifies operation, improves production efficiency, and eliminates the risks of working at height.

[0030] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
