Description

Technical Field

[0001] This utility model relates to the field of drawing frame technology, and in particular to a spinning drawing frame. Background Technology

[0002] The function of a drawing frame is to improve the internal structure of the sliver, thereby increasing its long-segment uniformity and reducing weight unevenness. It also straightens and parallels the fibers in the sliver, reduces hooks, ensures the fineness meets specifications, and ensures uniform mixing of different types or qualities of raw materials to achieve the specified blending ratio. Drawing frames are broadly classified into two categories based on their drafting mechanism: roller drafting frames and carding frames.

[0003] The existing patent with publication number CN221543605U relates to a drawing frame for spinning, which solves the problem in existing take-up equipment where, during the take-up process, the yarn experiences high friction with the outer wall of the bobbin due to the bobbin's inability to rotate, increasing the risk of yarn breakage. A drawing frame for spinning includes a drawing frame, a take-up bracket mounted on top of the drawing frame, and several take-up rollers connected to both sides of the take-up bracket; several mounting grooves corresponding to the take-up rollers are provided on both sides of the top of the drawing frame.

[0004] Because the positioning component can rotate inside the mounting slot, after the bobbin is connected to the top of the positioning component, when the yarn on the bobbin is wound up by the winding roller, the bobbin can rotate synchronously through the positioning component, thereby reducing the wear between the yarn and the outer wall of the bobbin and greatly reducing the risk of yarn breakage.

[0005] Although the device has the above advantages, the take-up roller in the device is mounted on the take-up bracket, and the position of the take-up roller is not easy to adjust. When stretching and winding different types of yarn, the yarn is prone to breakage due to uneven tension. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a spinning and drawing frame.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] This utility model discloses a spinning and drawing frame, comprising:

[0009] The base plate has a drawing frame body on one side of its top and a mounting plate fixedly installed on the other side of its top. The other end of the mounting plate is connected to the drawing frame body. The mounting plate has an L-shaped structure and four mounting slots are provided on the top of the base plate.

[0010] Four sets of limiting components are respectively disposed inside the mounting slot;

[0011] Four sets of winding assemblies are all mounted on the mounting plate, and each of the four sets of winding assemblies corresponds to one of the four sets of limiting assemblies. Each winding assembly includes a sliding plate, a threaded rod, a limiting plate, a fixing nut, and a winding roller.

[0012] The mounting plate has four sliding grooves inside, and each sliding groove has a limit groove at its top. The sliding plate is slidably disposed inside each of the four sliding grooves, and the threaded rod is fixedly installed on the top of each sliding plate. The threaded rod is disposed inside the limit groove and is slidably connected to the limit groove.

[0013] As a preferred technical solution of this utility model, the limiting component includes a bidirectional lead screw, a knob, a movable plate, and a limiting ring. One end of the bidirectional lead screw is fixedly installed with the knob, and the other end of the bidirectional lead screw extends into the interior of the mounting groove and is rotatably connected to the inner wall of the mounting groove.

[0014] As a preferred embodiment of this utility model, both sides of the bidirectional lead screw are threadedly connected to the movable plate, the movable plate is slidably connected to the mounting groove, and the top of the movable plate is fixedly installed with the limiting ring.

[0015] In a preferred embodiment of this invention, the limiting groove and the sliding groove are connected.

[0016] As a preferred technical solution of this utility model, the limiting plate is fixedly installed on the top of the threaded rod, the fixing nut is threadedly connected to the outside of the threaded rod, the size of the fixing nut is larger than the limiting groove, and the bottom surface of the fixing nut is treated with anti-slip treatment. The winding roller is rotatably installed on the outer side of the sliding plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model, by setting a limiting component, can conveniently clamp and fix both ends of the yarn tube, thereby facilitating the disassembly and installation of the yarn tube. This can improve the working efficiency of the device when changing yarn tubes, and can also fix yarn tubes of different sizes, so that the device can meet diverse processing needs.

[0019] 2. By setting up a winding assembly, the position of the winding roller can be easily adjusted, thereby changing the relative distance between the winding roller and the yarn bobbin, and thus adjusting the tension of the yarn. This allows the device to adapt to the drafting and winding requirements of different types of yarn, avoiding problems such as yarn breakage caused by uneven tension. Attached Figure Description

[0025] 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.

[0026] In the attached diagram, all identical reference numerals refer to the same components.

[0027] like Figure 1-3 As shown, this utility model provides a spinning and drawing frame, comprising:

[0028] The base plate 1 has a drawing frame body 2 on one side of its top and a mounting plate 3 fixedly installed on the other side of its top. The other end of the mounting plate 3 is connected to the drawing frame body 2. The mounting plate 3 has an L-shaped structure and four mounting slots 4 are provided on the top of the base plate 1.

[0029] Four sets of limiting components 5 are respectively installed inside the mounting slot 4;

[0030] Four sets of winding assemblies 6 are all mounted on the mounting plate 3, and each of the four sets of winding assemblies 6 corresponds to one of the four sets of limiting assemblies 5. The winding assembly 6 includes a sliding plate 601, a threaded rod 602, a limiting plate 603, a fixing nut 604, and a winding roller 605. The mounting plate 3 has four sliding grooves 7 inside, and each sliding groove 7 has a limiting groove 8 at the top. The limiting groove 8 is connected to the sliding groove 7.

[0031] Each of the four sliding grooves 7 has a sliding plate 601 slidably installed inside. Each sliding plate 601 has a threaded rod 602 fixedly installed on its top. The threaded rod 602 is located inside the limiting groove 8 and is slidably connected to the limiting groove 8.

[0032] Furthermore, the limiting component 5 includes a bidirectional lead screw 501, a knob 502, a moving plate 503, and a limiting ring 504. A knob 502 is fixedly installed at one end of the bidirectional lead screw 501, and the other end of the bidirectional lead screw 501 extends into the interior of the mounting groove 4 and is rotatably connected to the inner wall of the mounting groove 4.

[0033] Furthermore, both sides of the bidirectional lead screw 501 are threadedly connected to a movable plate 503, which is slidably connected to the mounting groove 4, and a limit ring 504 is fixedly installed on the top of each movable plate 503.

[0034] Furthermore, a limiting plate 603 is fixedly installed on the top of the threaded rod 602, and a fixing nut 604 is connected to the external thread of the threaded rod 602. The size of the fixing nut 604 is larger than that of the limiting groove 8, and the bottom surface of the fixing nut 604 is treated with anti-slip treatment. Winding rollers 605 are rotatably installed on the outer side of the slide plate 601. The slide plate 601 can be fixed by the fixing nut 604, and the top of the threaded rod 602 can be protected by the limiting plate 603 to prevent the fixing nut 604 from falling off.

[0035] Working principle: When in use, connect the device to an external power source, and then adjust the limiting ring 504 according to the required size of the yarn bobbin to be clamped and fixed.

[0036] By turning knob 502, the bidirectional lead screw 501 is rotated, which in turn moves the two moving plates 503 inward or outward simultaneously, thereby moving the limiting rings 504 and changing the distance between them. After adjustment, the yarn bobbin is placed between the limiting rings 504, and the two ends of the yarn bobbin are clamped by the limiting rings 504.

[0037] This device allows for convenient adjustment of the distance between the limiting rings 504, facilitating the disassembly and installation of the yarn bobbin. This improves the efficiency of the device when changing yarn bobbins and also allows for the fixing of yarn bobbins of different sizes, enabling the device to meet diverse processing needs.

[0038] During yarn drawing, the position of the winding roller 605 can be adjusted according to the characteristics of the yarn raw material. By turning the fixing nut 604 counterclockwise, the fixing nut 604 is separated from the mounting plate 3, losing its fixation to the slide plate 601. Then, with the cooperation of the slide groove 7, the slide plate 601, the threaded rod 602, and the limiting groove 8, the slide plate 601 can be moved, thereby changing the position of the winding roller 605. Then, by turning the fixing nut 604 clockwise, the slide plate 601 is fixed by the fixing nut 604. This allows the device to easily adjust the position of the winding roller 605, thereby changing the relative distance between the winding roller 605 and the yarn bobbin, and thus adjusting the yarn tension. This allows the device to adapt to the drafting and winding requirements of different types of yarn, avoiding problems such as yarn breakage caused by uneven tension. Then, the yarn can be drawn together by the main body 2 of the drawing frame.

[0039] Furthermore, both the limiting component 5 and the winding component 6 can be adjusted individually according to actual working needs, meeting diverse working requirements.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is 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.
