Description

Technical Field

[0001] This utility model relates to the field of yarn holder technology, specifically a double-sided yarn holder. Background Technology

[0002] The yarn creel is an important component of a braiding machine. When the braiding machine is working, the raw yarn is wound onto a yarn bobbin, which is then placed onto the yarn rod of the yarn creel, and the yarn is then fed to the textile equipment for braiding.

[0003] Utility model patent CN220724464U discloses a novel yarn frame, comprising a yarn frame body, a base, and a frame. Several notches are formed on the left and right inner side walls of the frame, and connecting holes are formed on the inner side walls of the notches. A central rod is fixed inside the frame. Several rotating blocks are rotatably connected to the outer side wall of the central rod. Support rods are fixed on both sides of the rotating blocks. Several yarn rods are fixed on both the front and rear sides of the support rods. A sliding cavity is formed inside the support rod. A through hole is formed on the cavity wall of the sliding cavity. A positioning block is slidably connected inside the sliding cavity. A spring is fixedly connected between one end of the positioning block and the cavity wall of the sliding cavity. A connecting rod is fixed to the other end of the positioning block. A movable structure is also provided inside the sliding cavity. This utility model realizes the switching between two working surfaces of the yarn frame body by rotating the support rod. When one working surface is working, yarn bobbins can be installed on the other working surface, thus saving time wasted on installing yarn bobbins during the textile process and improving textile efficiency.

[0004] However, when changing the working surface, the workers need to remove each support rod from the frame one by one and rotate each support rod one by one. The process of changing the working surface is not quick and convenient, and there is still room for improvement in this utility model.

[0005] Therefore, this utility model proposes a new technical solution to solve the problem that each support rod needs to be unfixed and rotated one by one, and the process of changing the working surface is not quick and convenient. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a double-sided yarn holder, which aims to achieve the technical effect of changing the working surface of the yarn holder body more quickly and conveniently.

[0007] A double-sided yarn frame includes a yarn frame body, which comprises a base, an outer frame, and an inner frame. The outer frame is fixed to the top of the base and is a ring-shaped structure formed by splicing two vertically symmetrically arranged side rods and two horizontally symmetrically arranged edge rods. The inner frame is rotatably connected to the inside of the outer frame. The inner frame includes a central rod and several support rods fixed to the left and right sides of the central rod. Several yarn rods are fixed to the front and rear sides of the support rods. Slots are provided at the center of opposite sides of the two side rods. The upper and lower ends of the central rod are respectively inserted into the two slots in a mating connection and rotate within the slots. Connecting grooves are provided on the outer walls of the left and right sides of the end of the central rod that is inserted into the slot. The interior of the side rods has a groove for connecting with the slots. The corresponding cavity has a sliding hole on the front outer side wall of the side rod that communicates with the cavity. A connecting rod and a sleeve are arranged inside the cavity. The sleeve is fixed inside the cavity and is a cylindrical structure with one end open towards the slot. One end of the connecting rod is slidably connected to the sleeve and is fixedly connected to the inner bottom wall of the sleeve with a spring. The other end of the connecting rod is slidably connected to the cavity and inserted into a connecting groove. A pressing rod is slidably connected in the sliding hole. One end of the pressing rod extends to the front side of the side rod, and the other end of the pressing rod extends into the cavity and is connected to the connecting rod with a force transmission structure. The force transmission structure is used to transmit the force on the pressing rod to the connecting rod and move the connecting rod into the sleeve.

[0008] By adopting the above technical solution, when it is necessary to change the working surface of the yarn frame body, the worker presses the upper pressing rod with their hand and simultaneously presses the lower pressing rod with their foot. The pressing rods move into the cavity along the sliding hole. The force on the pressing rods is transmitted to the force transmission structure, which then transmits the force to the connecting rod, causing the connecting rod to move into the sleeve. The end of the connecting rod that was originally inserted into the connecting groove is pulled out of the connecting groove, and at the same time, the spring is pressed to form a rebound force towards the slot. Then, the center rod is rotated until the connecting groove and the connecting rod are misaligned, and the pressing rod can be released. Then, the center rod is rotated again. At this time, under the action of the spring's rebound force, the connecting rod will press against the outer wall of the center rod. After the center rod rotates 180°, the connecting rod corresponds to another connecting groove. Under the action of the spring's rebound force, the end of the connecting rod that is away from the sleeve is inserted into another connecting groove, thereby fixing the center rod. The rotation of the center rod can drive several support rods to rotate simultaneously, realizing the simultaneous rotation and surface change of each support rod. This invention allows for a quicker and more convenient replacement of the working surface of the yarn frame body.

[0009] A further feature of this invention is that a first fixing ring, which is rotatably sleeved outside the central rod, is fixed at the center position of each of the two side rods on opposite sides.

[0010] By adopting the above technical solution, the setting of the first fixing ring improves the smoothness of the rotation of the center rod.

[0011] A further feature of this invention is as follows: a second fixing ring is fixed to the top of the first fixing ring and sleeved on the outside of the central rod. An arc-shaped groove is formed on the inner side wall of the second fixing ring. A positioning block is fixed on the outer side wall of the central rod for inserting into the arc-shaped groove and sliding along the arc-shaped groove. When the positioning block is in contact with one side wall of the arc-shaped groove, one of the two connecting grooves corresponds to the connecting rod. When the positioning block is in contact with the other side wall of the arc-shaped groove, the other connecting groove corresponds to the connecting rod.

[0012] By adopting the above technical solution, the center rod rotates, causing the positioning block to slide along the arc-shaped groove. When the positioning block is in contact with one side wall of the arc-shaped groove, one connecting groove corresponds to the connecting rod. When the positioning block is in contact with the other side wall of the arc-shaped groove, the other connecting groove corresponds to the connecting rod, thereby enabling the center rod to be positioned quickly.

[0013] A further feature of this invention is that a force-bearing plate is fixed to one end of the pressing rod that extends to the front side of the side rod.

[0014] By adopting the above technical solution, staff can more easily press the pressing rod using the force plate.

[0015] A further feature of this invention is that a limiting groove is provided on the wall of the sliding hole, and a limiting block is fixed on the pressing rod for inserting into the limiting groove and moving along the limiting groove.

[0016] By adopting the above technical solution, when the pressing rod slides along the sliding hole, the limiting block slides along the limiting groove. This prevents the pressing rod from falling off.

[0017] A further feature of this invention is as follows: the force transmission structure includes a pressing block, a pressing plate, and a fixing block. The fixing block is fixedly sleeved on the outside of the connecting rod. A first inclined surface is provided on the side of the fixing block facing away from the sleeve. One end of the pressing block is fixedly connected to the pressing rod. Two pressing plates are fixed to the other end of the pressing block. A gap is maintained between the two pressing plates for the connecting rod to pass through. Both pressing plates are provided with a second inclined surface that matches the first inclined surface.

[0018] By adopting the above technical solution, when the pressing rod moves along the sliding hole into the cavity, it drives the pressing block to move towards the fixed block. The pressing block drives the two pressing plates to move towards the fixed block. The second inclined surface presses against the first inclined surface, and the force on the first inclined surface can be decomposed into a force towards the sleeve. Under the action of this force, the fixed block moves towards the sleeve, and the fixed block drives the connecting rod to move into the sleeve.

[0019] Further features of this invention: The force transmission structure includes a rotating plate and a retaining ring. The retaining ring is fixedly sleeved on the outside of the connecting rod. One end of the rotating plate is rotatably connected to the pressing rod via a pin. The other end of the rotating plate is rotatably connected to the cavity via a pin and has two rotating blocks fixed thereon. A gap is maintained between the two rotating blocks so that the connecting rod can pass through. Both rotating blocks are in contact with the side of the retaining ring that is away from the sleeve.

[0020] By adopting the above technical solution, when the pressing rod moves along the sliding hole into the cavity, it pushes the rotating plate. Since one end of the rotating plate is rotatably connected to the pressing rod via a pin, and the other end of the rotating plate is rotatably connected to the cavity via a pin, the rotating plate will rotate under the push of the pressing rod. The rotating plate drives the rotating block to rotate. The rotating block presses the retaining ring, causing the retaining ring to move towards the sleeve. The retaining ring drives the connecting rod to move towards the inside of the sleeve.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1:

[0034] A double-sided yarn holder, such as Figures 1-5 As shown, it includes a yarn frame body. The yarn frame body includes a base 1, an outer frame 2, and an inner frame 3.

[0035] The outer frame 2 is fixed to the top of the base 1. The outer frame 2 is a ring structure spliced ​​together by two side rods 4 arranged symmetrically at the top and bottom and two side rods 5 arranged symmetrically at the left and right.

[0036] The inner frame 3 is rotatably connected to the interior of the outer frame 2. The inner frame 3 includes a central rod 6 and several support rods 7 fixed to the left and right sides of the central rod 6. Several yarn rods 8 are fixed to the front and rear sides of the support rods 7.

[0037] Each of the two side rods 4 has a slot 9 at the center of its opposite side. The upper and lower ends of the center rod 6 are inserted into the two slots 9 in a mating connection and rotate within the slots 9. Connecting grooves 10 are provided on the outer walls of the left and right sides of the end of the center rod 6 that is inserted into the slot 9.

[0038] The side rod 4 has an internal cavity 11 corresponding to the slot 9. A sliding hole 12 communicating with the cavity 11 is formed on the front outer wall of the side rod 4. A limiting groove 13 is formed on the wall of the sliding hole 12. A connecting rod 14 and a sleeve 15 are disposed inside the cavity 11. The sleeve 15 is fixed inside the cavity 11 and is a cylindrical structure with one end open towards the slot 9. One end of the connecting rod 14 is slidably inserted into the sleeve 15 and a spring 16 is fixedly connected between it and the inner bottom wall of the sleeve 15. The other end of the connecting rod 14 is slidably inserted out of the cavity 11 and into a connecting groove 10. A pressing rod 17 is slidably connected in the sliding hole 12. A limiting block 18 is fixed on the pressing rod 17 for inserting into and moving along the limiting groove 13. One end of the pressing rod 17 extends to the front of the side rod 4 and is fixed with a force-bearing plate 19. The other end of the pressing rod 17 extends into the cavity 11 and a force transmission structure is provided between it and the connecting rod 14.

[0039] The force transmission structure is used to transmit the force on the pressing rod 17 to the connecting rod 14, causing the connecting rod 14 to move into the sleeve 15. The force transmission structure includes a pressing block 20, pressing plates 21, and a fixing block 22. The fixing block 22 is fixedly sleeved on the outside of the connecting rod 14. A first inclined surface 23 is provided on the side of the fixing block 22 facing away from the sleeve 15. One end of the pressing block 20 is fixedly connected to the pressing rod 17. Two pressing plates 21 are fixed to the other end of the pressing block 20. A gap is maintained between the two pressing plates 21 for the connecting rod 14 to pass through. Both pressing plates 21 are provided with a second inclined surface 24 that matches the first inclined surface 23.

[0040] Each of the two side rods 4 has a first retaining ring 25 fixed at the center position on its opposite side, which is rotatably sleeved on the outside of the central rod 6 via a bearing. The first retaining ring 25 improves the smoothness of the rotation of the central rod 6.

[0041] A second fixing ring 26 is fixed to the top of the first fixing ring 25 and sleeved on the outside of the center rod 6. An arc-shaped groove 27 is formed on the inner side wall of the second fixing ring 26. A positioning block 28 is fixed on the outer side wall of the center rod 6 for inserting into the arc-shaped groove 27 and sliding along the arc-shaped groove 27.

[0042] Working principle: When the working surface of the yarn frame body needs to be replaced, the worker presses the upper pressing rod 17 with their hand through the force plate 19, and simultaneously presses the lower pressing rod 17 with their foot through the force plate 19. The pressing rod 17 moves along the sliding hole 12 into the cavity 11. When the pressing rod 17 slides along the sliding hole 12, the limiting block 18 slides along the limiting groove 13, which can prevent the pressing rod 17 from falling off. The pressing rod 17 drives the pressing block 20 to move towards the fixing block 22. The pressing block 20 drives the two pressing plates 21 to move towards the fixing block 22. The second inclined surface 24 presses on the first inclined surface 23. The force on the first inclined surface 23 can be decomposed into a force towards the sleeve 15. Under the action of this force, the fixing block 22 moves towards the sleeve 15, and the fixing block 22 drives the connecting rod 14 to move into the sleeve 15. The end of the connecting rod 14 that was originally inserted into the connecting groove 10 is pulled out of the connecting groove 10. At the same time, the spring 16 is pressed to generate a rebound force toward the slot 9.

[0043] Next, rotate the center rod 6 until the connecting groove 10 is misaligned with the connecting rod 14, then release the pressing rod 17.

[0044] Then continue rotating the center rod 6. At this time, under the action of the rebound force of the spring 16, the connecting rod 14 will press against the outer wall of the center rod 6.

[0045] When the center rod 6 rotates, it causes the positioning block 28 to slide along the arc-shaped groove 27. After the center rod 6 rotates 180°, the positioning block 28 fits against the other side wall of the arc-shaped groove 27, and the connecting rod 14 corresponds to another connecting groove 10. Under the action of the rebound force of the spring 16, the end of the connecting rod 14 that is away from the sleeve 15 is inserted into the other connecting groove 10, thereby fixing the center rod 6. The rotation of the center rod 6 can drive several support rods 7 to rotate simultaneously, realizing the simultaneous rotation and face change of each support rod 7.

[0046] This invention allows for a quicker and more convenient replacement of the working surface of the yarn frame body.

[0047] Example 2:

[0048] The difference from Embodiment 1 is that the force transmission structure no longer includes the pressing block 20, the pressing plate 21, and the fixing block 22, but instead is as follows: Figures 6-8 As shown, the device includes a rotating plate 29 and a retaining ring 30, with the retaining ring 30 fixedly sleeved on the outside of the connecting rod 14. One end of the rotating plate 29 is rotatably connected to the pressing rod 17 via a pin. The other end of the rotating plate 29 is rotatably connected to the cavity 11 via a pin and has two rotating blocks 31 fixed thereon. A gap is maintained between the two rotating blocks 31, allowing the connecting rod 14 to pass through. Both rotating blocks 31 are in contact with the side of the retaining ring 30 facing away from the sleeve 15.

[0049] When the pressing rod 17 moves along the sliding hole 12 into the cavity 11, it pushes the rotating plate 29. Since one end of the rotating plate 29 is rotatably connected to the pressing rod 17 via a pin, and the other end of the rotating plate 29 is rotatably connected to the cavity 11 via a pin, the rotating plate 29 will rotate under the push of the pressing rod 17. The rotating plate 29 drives the rotating block 31 to rotate. The rotating block 31 presses the retaining ring 30, causing the retaining ring 30 to move toward the sleeve 15. The retaining ring 30 drives the connecting rod 14 to move toward the sleeve 15.
