Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a textile warp threading frame. Background Technology

[0002] Warp threading involves inserting warp yarns into the heddle holes and reed teeth. This further temporarily and locally fixes the warp yarns in terms of their arrangement order, width, and density. In other words, it prevents relative movement of the warp yarns near the heddle and reed in the right direction under the control of the reed teeth, leaving only some room for relative movement in the up-down direction. A search revealed a patent with application number CN202221199717.X, which discloses a textile warp threading frame. When the threading pieces are fully loaded, an electric push rod drives a rack in conjunction with a telescopic rod and a sliding wheel to advance the frame. Simultaneously, the rack drives a gear to rotate, which in turn drives a round rod, a hanging plate, a hook, and the threading pieces to rotate at a certain angle. Then, a tool is manually inserted into the holes of four threading pieces in a row to hook out the yarn. Hooks extend from the bottom of the threading plate to hook the yarn into the bottom of the threading plate. Before threading, all the threading pieces are pre-adjusted to the appropriate angle, eliminating the need for manual adjustment.

[0003] The above-mentioned device uses electric push rods to replace manual operation, reducing labor costs. However, it still requires the movement of the warp threading plate and is difficult to automatically adjust the state of the warp threading frame according to the position of the yarn so that the yarn can be automatically limited after passing through, thereby reducing the control commands of the warp threading frame. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a textile warp threading frame that solves the technical problem that existing warp threading frames cannot automatically adjust their state according to the position of the yarn, thereby automatically limiting the yarn after it passes through and reducing the number of control commands required for the warp threading frame.

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

[0006] A textile warp threading frame includes a frame, with a crossbar installed inside the frame and a force-bearing locking assembly installed on the crossbar;

[0007] The force-bearing positioning assembly includes a swing frame, a baffle, and a spring. The swing frame is rotatably connected to the crossbar, the baffle is fixedly connected to the swing frame and corresponds to the number of swing frames, and the spring is installed between the swing frame and the crossbar.

[0008] Furthermore, the swing frame includes a left end plate, a middle plate, and a right end plate. The length of the left end plate is less than the length of the right end plate, and a notch is provided at the top of the right end plate.

[0009] Furthermore, a longitudinal groove adapted to the swing frame is provided on one side of the baffle, and an arc-shaped plate is fixedly connected to the side of the swing frame away from the baffle.

[0010] Furthermore, an arc-shaped rod is rotatably connected to the bottom inner side of the swing frame, and metal balls are fixedly connected to both sides of the inner wall of the swing frame.

[0011] Furthermore, a slot adapted to the arc-shaped rod is provided on one side of the metal ball, and a fin penetrating the swing frame is provided on one side of the metal ball.

[0012] Furthermore, an exhaust box is rotatably connected to the bottom inner side of the frame, and a positioning plate is fixedly connected to the top inner side of the frame.

[0013] Furthermore, both sides of the exhaust box are rotatably connected to side plates. One side of the side plate is provided with a threaded rod that movably passes through the positioning plate. The threaded rod is slidably connected to the side plate. One side of the positioning plate is provided with a track groove corresponding to the threaded rod.

[0015] Beneficial effects:

[0016] 1. This utility model is designed to automatically adjust the state of the warp threading frame according to the position of the yarn.

[0024] 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.

[0025] Example

[0026] To achieve the goal of automatically limiting the yarn position after it passes through the warp threader, please refer to... Figures 1-3 This embodiment proposes a textile warp threading frame, including a frame 1. A crossbar 2 is installed inside the frame 1. A force-bearing locking component 3 is installed on the crossbar 2. The force-bearing locking component 3 includes a swing frame 31, a baffle 32, and a spring 33. The swing frame 31 is rotatably connected to the crossbar 2. The baffle 32 is fixedly connected to the swing frame 31 and corresponds to the number of swing frames 31. The spring 33 is installed between the swing frame 31 and the crossbar 2. The swing frame 31 includes a left end plate 311, a middle plate 312, and a right end plate 313. The length of the left end plate 311 is less than the length of the right end plate 313. A notch is opened at the top of the right end plate 313. A longitudinal groove 4 adapted to the swing frame 31 is opened on one side of the baffle 32. An arc-shaped plate 5 is fixedly connected to the side of the swing frame 31 away from the baffle 32.

[0027] In use, spring 33 pushes the swing frame 31 to maintain a tilted balance. At this time, the opening of the swing frame 31 faces upward, and the arc plate 5 guides the yarn into the swing frame 31, reducing the possibility of the yarn falling off the swing frame 31 and onto the crossbar 2. When the yarn passes through the warp threading frame, the yarn enters the swing frame 31 through the opening at the top of the swing frame 31. Then, when the yarn is pulled, it presses the swing frame 31 downward, pushing the swing frame 31 to rotate downward and press the spring 33, causing the swing frame 31 to gradually approach the baffle 32. At this time, the right end plate 313, due to its notch, has a smaller width. After gradually approaching the baffle 32, it passes through the longitudinal groove 4 until the left end plate 311 rotates to the baffle 32. The left end plate 311 is blocked by the baffle 32 and presses against the baffle 32. At this time, the yarn is completely wrapped by the swing frame 31 and the baffle 32 to complete the limit. The yarn cannot fall off the warp threading frame. The state of the warp threading frame can be automatically adjusted according to the position of the yarn. The force of the yarn on the warp threading frame when it is pulled can be used to automatically limit the yarn after it passes through, thereby reducing the control commands of the warp threading frame.

[0028] Because the yarn generates heat through friction as it passes through the warp threader, in order to improve the cooling capacity for both the warp threader and the yarn passing through it, refer to... Figure 2 An arc-shaped rod 6 is rotatably connected to the bottom inner side of the swing frame 31. Metal balls 7 are fixedly connected to both sides of the inner wall of the swing frame 31. A slot 8 adapted to the arc-shaped rod 6 is opened on one side of the metal ball 7. A fin 9 penetrating the swing frame 31 is provided on one side of the metal ball 7. Both ends of the arc-shaped rod 6 extend movably into the slot 8.

[0029] In use, after the yarn enters the swing frame 31, its bottom is supported by the arc-shaped rod 6. The arc-shaped rod 6 reduces the friction between the yarn and the warp threading frame. After being pulled, the yarn moves along the arc-shaped rod 6. The heat generated by the friction between the yarn and the arc-shaped rod 6 is transferred to the metal ball 7, and then transferred to the surrounding air for heat dissipation through the fins 9. At the same time, since the yarn moves laterally when passing through the warp threading frame, it pushes the arc-shaped rod 6 to the left or right, which in turn causes the contact area between the arc-shaped rod 6 and the metal ball 7 on the left and right sides to change continuously. This improves the cooling effect on the yarn and the warp threading frame, and changes the proportion of heat generated during the friction between the yarn and the warp threading frame that is transferred to the metal balls 7 on the left and right sides for cooling. This reduces the possibility that the cooling effect on the yarn will weaken after one side of the metal ball 7 is continuously heated.

[0030] To reduce the heat generated by friction during yarn passing through the warp threading frame and thus achieve better cooling of the frame, refer to... Figure 3An exhaust box 10 is rotatably connected to the bottom inner side of the frame 1, and a positioning plate 11 is fixedly connected to the top inner side of the frame 1. Side plates 12 are rotatably connected to both sides of the exhaust box 10. A threaded rod 13 is provided on one side of the side plate 12, which movably passes through the positioning plate 11. The threaded rod 13 is slidably connected to the side plate 12. A track groove corresponding to the threaded rod 13 is opened on one side of the positioning plate 11. A nut 14 is installed at the end of the threaded rod 13 away from the side plate 12.

[0031] In use, adjust the angle of the exhaust box 10 as needed so that the exhaust box 10 faces the crossbar 2 and the force-bearing clamping assembly 3. Then slide the threaded rod 13 along the side plate 12 so that the threaded rod 13 passes through the track groove on the positioning plate 11. Finally, rotate the nut 14 to gradually approach the positioning plate 11 until the nut 14 is pressed against the positioning plate 11, fixing the exhaust box 10 at a fixed angle to the positioning plate 11. After starting the exhaust box 10, the yarn on the crossbar 2 is cooled by air. The blowing angle can be adjusted as needed to improve the cooling effect on the yarn passing through the warp threading frame by using air cooling.
