Description

Technical Field

[0001] This utility model belongs to the field of steel reed technology, and in particular relates to a steel reed that is easy to replace the reed blades. Background Technology

[0002] In traditional textile equipment, a beat-up mechanism is usually used. The newly introduced weft yarn is still some distance from the weft inlet. In order to weave a fabric with a certain weft density, the weft yarn needs to be moved towards the weft inlet by the beat-up mechanism and interweave with the warp yarn. The reed is an essential component in textile equipment. As the usage time increases, the reed will wear down and needs to be replaced to continue to be used. However, the reed is usually a whole unit, which makes it inconvenient to replace the damaged reed individually, and maintenance is not convenient.

[0003] For example, Chinese patent application CN220927090U discloses a reed box with replaceable reeds, including multiple reed units connected end to end. Each reed unit includes a reed body, a fixing block, a post, and a hole. There are two fixing blocks, and multiple reed bodies are fixedly connected between the two fixing blocks at equal intervals. A post is fixedly connected to one side of each fixing block, and a hole corresponding to the post is opened on the other side of each fixing block. Fixing components are provided on both the upper and lower sides of each reed unit. This replaceable reed reed, through the arrangement of multiple reed units, is assembled by inserting the post of the first reed unit into the fixing hole of the fixing frame during installation, then inserting the post of the next reed unit into the hole of the previous reed unit, until the entire fixing frame is filled. Then, the fixing post on the fixing plate is inserted into the hole of the last reed unit, and nuts are used to fix the mounting plate and the fixing plate, thus completing the assembly of the reed.

[0004] However, the above has the following shortcomings:

[0005] 1. In the above patent, although the reed can be disassembled by setting up an installation plate, a fixing plate and a plug, the disassembly process requires separating the fixing plate, the installation plate and the reed before removing the reed. The disassembly steps are cumbersome and inconvenient, and the portability of the reed needs to be improved.

[0006] 2. During the weaving process, the reed is affected by the vibration of the loom, which makes it impossible for the reed to guide the yarn stably. The vibration of the reed may cause the yarn to be subjected to additional stress, increasing the risk of yarn breakage and thus affecting the quality of the fabric. The stability of the steel reed needs to be improved. Utility Model Content

[0007] To overcome the shortcomings of existing technology, this utility model provides a steel reed that facilitates reed replacement. By creating upper and lower disassembly grooves on the upper and lower hollow reed seats, the reed can be removed from the steel reed independently without disassembling the reed seat and reed frame, thus facilitating reed removal. The upper and lower positioning posts, pressing and rotating grooves, and shock-absorbing springs allow the reed to be disassembled by pressing, further enhancing the ease of disassembly. Simultaneously, the combination of elastic limiting blocks and shock-absorbing springs reduces vibration of the reed from the loom, thereby reducing friction between the reed and the yarn caused by vibration, reducing the risk of yarn breakage, extending the service life of the reed, and enhancing the stability of the steel reed.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a steel reed that facilitates reed replacement, comprising a reed frame and reeds. A lower hollow reed seat is fixedly provided at the bottom of the reed frame. A plurality of lower disassembly grooves are provided at the top of the lower hollow reed seat. An upper reed seat is fixedly provided at the top of the reed frame. A plurality of upper disassembly grooves are provided at the top of the upper reed seat. An upper positioning post is detachably connected to the upper disassembly groove. The reed is fixedly connected to one end of the upper positioning post near the lower hollow reed seat, and the reed can slide within the upper disassembly groove. A lower positioning post is fixedly connected to one end of the reed near the lower hollow reed seat. The lower positioning post is detachably connected to the lower disassembly groove. An elastic limiting block is fixedly connected to the side wall of the lower positioning post. The elastic limiting block can pass through the lower disassembly groove and be fixed inside the lower hollow reed seat.

[0009] Furthermore, a pressing and rotating groove is provided on the lower hollow reed base, and the pressing and rotating groove is connected through to the side wall of the lower disassembly groove, so that the reed can rotate along the bottom wall of the pressing and rotating groove.

[0010] Furthermore, a plurality of limiting block grooves are provided on the inner top wall of the lower hollow reed base. The elastic limiting block is detachably connected to the limiting block groove. The limiting block groove is parallel to the side wall of the reed frame, and the groove width is the same as the width of the elastic limiting block.

[0011] Furthermore, the bottom of the lower hollow reed seat is bolted to a lower reed frame cover plate, a telescopic rod is fixedly mounted on the lower reed frame cover plate, a shock-absorbing spring is sleeved on the telescopic rod, a connecting seat is fixedly mounted on the top of the telescopic rod, and the lower positioning column is detachably connected to the connecting seat.

[0012] Furthermore, a connecting block is fixed at one end of the upper positioning post and the lower positioning post near the reed, and the reed is bolted to the connecting block.

[0013] Furthermore, the groove depth of the limiting block groove is less than that of the pressing and rotating groove, the opening of the lower disassembly groove is directly opposite the upper disassembly groove, and the height of the upper positioning post and the lower positioning post is greater than the groove depth of the upper disassembly groove and the lower disassembly groove.

[0014] In summary, compared with existing technologies, the beneficial effects of this solution are as follows:

[0015] (1) By opening an upper disassembly groove and a lower disassembly groove on the reed, each reed piece can be removed from the reed without disassembling the reed seat and reed frame, which improves the portability of disassembly. Furthermore, by setting an upper positioning post, a lower positioning post, a pressing and rotating groove and a telescopic rod, the reed pieces can be disassembled and installed by pressing, which further improves the convenience of reed disassembly.

[0016] (2) By setting elastic limit blocks and shock-absorbing springs, the vibration of the loom to the steel reed can be reduced, thereby reducing the friction between the reed and the yarn caused by vibration, reducing the wear of the reed and the risk of yarn breakage, improving the quality of the fabric, and extending the service life of the reed.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 A steel reed that facilitates reed replacement includes a reed frame 10 and reed pieces 17. An upper reed seat 12 is fixedly provided on the top of the reed frame 10, and a lower hollow reed seat 13 is fixedly provided on the bottom of the reed frame 10. Several upper disassembly grooves 11 are provided on the top of the upper reed seat 12. An upper positioning post 16 is slidably connected to the upper disassembly groove 11. The reed pieces 17 are fixedly connected to one end of the upper positioning post 16 near the lower hollow reed seat 13. The upper positioning post 16 and the reed pieces 17 can pass through the upper disassembly grooves 11.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, a lower positioning post 18 is fixedly connected to one end of the reed 17 near the lower hollow reed base 13. Several lower disassembly grooves 14 are opened on the top of the lower hollow reed base 13, and the opening of the lower disassembly groove 14 is directly opposite the upper disassembly groove 11. The reed 17 and the lower positioning post 18 are detachably connected to the lower disassembly groove 14 and slide in the lower disassembly groove 14. The height of the upper positioning post 16 and the lower positioning post 18 is greater than the groove depth of the upper disassembly groove 11 and the lower disassembly groove 14.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, a pressing and rotating groove 22 is provided on the top of the lower hollow reed seat 13. The pressing and rotating groove 22 is connected through to the side wall of the lower disassembly groove 14. The reed 17 can rotate along the bottom wall of the pressing and rotating groove 22. An elastic limiting block 19 is fixed at the end of the lower positioning post 18 away from the reed 17. The elastic limiting block 19 can pass through the lower disassembly groove 14 and is detachably connected to the lower hollow reed seat 13. A lower reed frame cover plate 15 is bolted to the bottom of the lower hollow reed seat 13. A telescopic rod 25 is fixed on the lower reed frame cover plate 15. A shock-absorbing spring 20 is sleeved on the telescopic rod 25. A connecting seat 21 is fixed on the top of the telescopic rod 25. The lower positioning post 18 is detachably connected to the connecting seat 21.

[0031] By opening an upper disassembly groove 11 and a lower disassembly groove 14 on the upper reed seat 12 and the lower hollow reed seat 13, each reed piece 17 can be removed from the reed frame 10 individually, improving the portability of disassembly. Furthermore, through the cooperation of the upper positioning post 16, the lower positioning post 18, the pressing and rotating groove 22, and the telescopic rod 25, the reed piece 17 can be disassembled and installed by pressing, further improving the convenience of disassembling the reed piece 17.

[0032] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 , Figure 9 As shown, several limiting block grooves 23 are provided on the inner top wall of the lower hollow reed base 13. The limiting block grooves 23 are parallel to the side wall of the reed frame 10. The elastic limiting block 19 is detachably connected to the limiting block groove 23, and the groove width of the limiting block groove 23 is the same as the width of the elastic limiting block 19. The groove depth of the limiting block groove 23 is less than the pressing and rotating groove 22. A connecting block 24 is fixed on the end face of the upper positioning post 16 and the lower positioning post 18 near the reed piece 17. The reed piece 17 and the connecting block 24 are bolted together.

[0033] By setting the elastic limit block 19 and the shock-absorbing spring 20 together, the horizontal and vertical vibrations of the reed can be reduced, thereby reducing the friction between the reed and the yarn, reducing the wear of the reed and the risk of yarn breakage, improving the quality of the fabric, and extending the service life of the reed.

[0034] In this embodiment, initially, the power supply to the loom connected to the reed is disconnected, causing the loom to stop working. The operator locates the reed 17 that needs to be replaced and presses the corresponding upper positioning post 16 on top. After the upper positioning post 16 is pressed, it causes the reed 17 to descend together. When the reed 17 abuts against the bottom wall of the pressing and rotating groove 22, the top of the elastic limiting block 19 is located below the groove opening of the limiting block groove 23 and disengages from the limiting block groove 23. The operator continues to press and rotates the upper positioning post 16. When the reed 17 rotates to abut against the side wall of the lower disassembly groove 14, the upper positioning post 16 is slowly released. At this time, the reed 17 rises a short distance under the elastic force of the shock-absorbing spring 20 and is located in the groove between the upper disassembly groove 11 and the lower disassembly groove 14.

[0035] The operator then lifts the upper positioning post 16. The reed 17 slides in the upper disassembly groove 11 along with the upper positioning post 16. At the same time, the lower positioning post 18 also slides in the lower disassembly groove 14 and separates from the connecting seat 21. As the upper positioning post 16 is lifted, the lower positioning post 18 first passes through the lower disassembly groove 14 and finally passes through the upper disassembly groove 11. At this time, the reed 17 is completely separated from the reed frame 10, and the disassembly of the reed 17 is completed.

[0036] The operator then loosens the bolts on the connecting block 24, removes the reed 17 to be replaced from the upper positioning post 16 and the lower positioning post 18, inserts the reed 17 to be installed into the groove of the connecting block 24, tightens the bolts, and re-fixes the reed 17 to be installed with the upper positioning post 16 and the lower positioning post 18. Then, the operator aligns the lower positioning post 18 and the reed 17 with the upper disassembly groove 11 and slowly places them into the reed frame 10. After the lower positioning post 18 abuts against the connecting seat 21, the operator presses down the upper positioning post 16. At this time, the reed 17 is located above the bottom wall of the pressing rotating groove 22 and the elastic limiting block 19 is located inside the lower hollow reed seat 13.

[0037] The operator then maintains pressure on the upper positioning post 16 and rotates the reed 17 towards the side wall of the pressing rotation groove 22 at a certain angle. The elastic limiting block 19 rotates to below the inner top wall of the lower hollow reed seat 13. The operator releases the upper positioning post 16, and the elastic limiting block 19 abuts against the inner top wall of the lower hollow reed seat 13 under the action of the shock-absorbing spring 20. The operator continues to rotate the reed 17 towards the side wall of the pressing rotation groove 22. When the elastic limiting block 19 rotates to below the limiting block groove 23, the elastic limiting block 19 is engaged in the limiting block groove 23 under the elastic force of the shock-absorbing spring 20, and the installation of the reed 17 is completed.

[0038] The aforementioned shock-absorbing spring 20 and telescopic rod 25 are mature existing technologies, and will not be described in detail here.
