Description

Technical Field

[0001] This utility model relates to the field of weft yarn frame technology, specifically a weft yarn frame with an adjustable function. Background Technology

[0002] Chinese Patent Publication No. CN202320535722.1 discloses a clamping weft yarn frame, including a support plate. A support sleeve rod is mounted on the top of the support plate, and an adjusting sleeve is mounted on the outside of the top of the support sleeve rod. A lifting rod passes through the adjusting sleeve and the top of the support sleeve rod. An installation groove is formed on one side of the lifting rod, and installation blocks are evenly installed inside the installation groove. This invention uses downward rotation of the adjusting cylinder to move the lifting ring upward, causing the clamping blocks to be pressed inward by the guide block and guide groove. Through the cooperation of multiple clamping blocks, the position of the lifting rod is fixed. By adjusting the extension height of the lifting rod, the height of the weft yarn bobbin can be adjusted, making the weft yarn frame suitable for the production needs of weaving machines of different heights, thus facilitating yarn feeding during weaving and improving the applicability of the weft yarn frame.

[0003] Although this weft yarn holder can adjust the height of the weft yarn bobbin, the installation and adjustment process is quite troublesome, and the angle of the weft yarn bobbin cannot be adjusted, making it unsuitable for different usage situations.

[0004] To address the aforementioned issues, we have made improvements by proposing a weft yarn holder with an adjustable function. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model provides a weft yarn frame with an adjustable function, including a support plate and a support frame. The interior of the support frame is divided into several partition cavities by several fixedly installed partition plates. Each of the partition cavities is slidably connected to a movable plate. The interior of the support frame is rotatably installed with several segmented threaded rods, and the threaded segments of the segmented threaded rods correspond one-to-one with the partition cavities.

[0007] The support frame is externally slidably connected to several sliding blocks. The front of each sliding block is connected to a rotating cylinder and a fixed block. Limiting components are installed at the front and rear ends of the rotating cylinder, and an electric telescopic rod is connected to the upper part of the fixed block.

[0008] As a preferred embodiment of this utility model, a connecting frame is fixedly connected to the front side of the sliding block, and an extension member is hinged to the end of the connecting frame. The maximum angle is when the connecting frame and the extension member are parallel. The other end of the extension member is fixedly connected to the fixed block. The electric telescopic rod is fixedly installed on the upper part of the sliding block, and a connecting rod is hinged to the end of the electric telescopic rod. The other end of the connecting rod is hinged to the upper part of the fixed block.

[0009] As a preferred technical solution of this utility model, the rotating cylinder is fixedly connected to the fixed block, and threaded grooves are respectively opened at the front and rear ends of the rotating cylinder. The two limiting members are respectively threadedly connected to the rotating cylinder through the threaded grooves, and a reserved groove is opened on the side surface of the limiting member.

[0010] As a preferred embodiment of this utility model, a plurality of balls are placed inside the reserved groove, and a retaining element is rotatably installed inside the reserved groove. The inner surface of the retaining element is in contact with the balls, and the retaining elements of the two limiting members are installed opposite to each other.

[0011] As a preferred technical solution of this utility model, the plurality of movable plates are respectively threadedly connected to one of the segmented threaded rods and slidably connected to the remaining segmented threaded rods. A sliding groove is provided on the front surface of the support frame, and the plurality of sliding blocks respectively pass through the sliding groove and are fixedly connected to the movable plate.

[0012] As a preferred embodiment of this utility model, the top of the support frame is rotatably mounted with several knobs, and the knobs are respectively coaxially and fixedly connected to several segmented threaded rods.

[0013] In a preferred embodiment of this invention, the support frame is fixedly connected to the support plate.

[0014] The beneficial effects of this utility model are:

[0015] This type of adjustable weft frame can adjust the height of different sliding blocks by turning the knob to drive the segmented threaded rod. It can adapt to the weaving needs of different heights and does not need to be disassembled during use. It can not only maintain the overall stability of the weft frame, but also reduce the difficulty of use and operation.

[0016] By controlling the length of the electric telescopic rod, the angle between the rotating drum and the support frame can be adjusted, so that the weft yarn frame can meet different usage requirements. Furthermore, by twisting the two limiting parts to adjust their position, the two limiting parts can clamp weft yarn drums of different widths. The clamping parts and ball bearings can reduce the friction between the weft yarn drum and the limiting parts, thus reducing the impact on the weft yarn drum's threading.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figure 1-3 As shown, a weft yarn frame with adjustable function includes a support plate 1 and a support frame 2. The interior of the support frame 2 is divided into several partition cavities 11 by several fixedly installed partition plates 9. Movable plates 10 are slidably connected in the partition cavities 11 respectively. Several segmented threaded rods 8 are rotatably installed inside the support frame 2. The threaded segments of the several segmented threaded rods 8 correspond one-to-one with the partition cavities 11 respectively.

[0025] The support frame 2 has several sliding blocks 5 externally connected. The front of the sliding block 5 is connected to a rotating cylinder 6 and a fixed block 14. Limiting parts 13 are installed at the front and rear ends of the rotating cylinder 6 respectively. An electric telescopic rod 7 is connected to the upper part of the fixed block 14.

[0026] A connecting frame 15 is fixedly connected to the front side of the sliding block 5. An extension member 16 is hinged to the end of the connecting frame 15. The maximum angle is when the connecting frame 15 and the extension member 16 are parallel, so that the angle between the extension member 16 and the connecting frame 15 is maintained at 90°-180°. The other end of the extension member 16 is fixedly connected to the fixed block 14. The electric telescopic rod 7 is fixedly installed on the upper part of the sliding block 5. A connecting rod 17 is hinged to the end of the electric telescopic rod 7. The other end of the connecting rod 17 is hinged to the upper part of the fixed block 14. When the electric telescopic rod 7 is extended, the angle between the connecting frame 15 and the extension member 16 increases. When the electric telescopic rod 7 is shortened, the angle between the connecting frame 15 and the extension member 16 decreases. By controlling the length of the electric telescopic rod 7, the angle of the rotating drum 6 can be adjusted to adjust the weft yarn guide angle.

[0027] The rotating drum 6 is fixedly connected to the fixed block 14. Threaded grooves 12 are opened at the front and rear ends of the rotating drum 6 respectively. Two limiting members 13 are threadedly connected to the rotating drum 6 through the threaded grooves 12 respectively. A reserved groove 19 is opened on the side surface of the limiting member 13.

[0028] like Figure 4 As shown, a number of balls 20 are placed inside the reserved groove 19, and a retainer 18 is rotatably installed inside the reserved groove 19. The inner surface of the retainer 18 is in contact with the balls 20, and the retainers 18 of the two limiting members 13 are installed opposite each other.

[0029] After the weft yarn bobbin is placed on the outside of the rotating drum 6, the limiting member 13 is rotated according to the length of the weft yarn bobbin to adjust the distance between the two limiting members 13 until the two clamping members 18 clamp the two sides of the weft yarn bobbin. When the weft yarn bobbin is pulled and rotated, the clamping member 18 rotates accordingly. At the same time, the ball bearing 20 can reduce the friction between the clamping member 18 and the limiting member, and prevent the weft yarn bobbin from driving the limiting member 13 to rotate and causing it to shift.

[0030] like Figure 1-4 As shown, several movable plates 10 are threadedly connected to one of the segmented threaded rods 8 and slidably connected to the other segmented threaded rods 8. A groove 3 is provided on the front surface of the support frame 2. Several sliding blocks 5 pass through the groove 3 and are fixedly connected to the movable plates 10. The height of the movable plates 10 can be adjusted by rotating the segmented threaded rods 8, that is, the height of the rotating drum 6 and the weft yarn drum can be adjusted.

[0031] Several knobs 4 are rotatably mounted on the top of the support frame 2, and the knobs 4 are coaxially fixedly connected to several segmented threaded rods 8.

[0032] The support frame 2 is fixedly connected to the support plate 1.

[0033] Working principle: In use, this type of adjustable weft yarn scaffold is operated by placing the weft yarn bobbin on the outside of the rotating drum 6. The distance between the two limiting members 13 is adjusted by rotating the limiting member 13 according to the length of the weft yarn bobbin until the two clamping members 18 clamp the two sides of the weft yarn bobbin. When the weft yarn bobbin is pulled and rotated, the clamping member 18 rotates accordingly. At the same time, the ball bearing 20 reduces the friction between the clamping member 18 and the limiting member, preventing the weft yarn bobbin from rotating and causing the limiting member 13 to shift. The height of the moving plate 10 can be adjusted by rotating the segmented threaded rod 8, that is, the height of the rotating drum 6 and the weft yarn bobbin. When the electric telescopic rod 7 is extended, the angle between the connecting frame 15 and the extension member 16 increases. When the electric telescopic rod 7 is shortened, the angle between the connecting frame 15 and the extension member 16 decreases. By controlling the length of the electric telescopic rod 7, the angle of the rotating drum 6 can be adjusted to adjust the yarn feeding angle of the weft yarn scaffold.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
