Description

Technical Field

[0001] This utility model relates to the field of drawing frame technology, specifically to a drawing frame feeding device. Background Technology

[0002] A drawing frame is an important piece of equipment used in cotton mills, mainly for drawing, drafting, and leveling cotton slivers. Its main functions are to improve the internal structure of the sliver, increase the uniformity of its long segments, reduce weight unevenness, straighten and parallel fibers, reduce hooks, ensure fineness meets specifications, and evenly mix different types or qualities of raw materials to achieve the specified mixing ratio.

[0003] Conventional sliver feeding devices convey cotton slivers using conveyor rollers and other devices. However, due to the limited surface structure of the conveyor rollers, each cotton sliver may interfere with each other during conveying, affecting subsequent processing.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a drawing frame feeding device. Utility Model Content

[0005] The purpose of this invention is to provide a sliver feeding device for a drawing frame to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sliver feeding device for a drawing frame, comprising a lead screw and conveying wheels. The surface of the lead screw is provided with conveying wheels, and support piles are installed at both ends of the lead screw. An adjusting frame is connected to the side of the support pile away from the lead screw, and a movable seat is installed at the bottom of the support pile. A guide rail is connected to the bottom of the movable seat. The conveying wheel includes a guide wheel, a precision bearing, and a limiting nut. A precision bearing is installed at the axis of the guide wheel, and limiting nuts are provided on both sides of the precision bearing.

[0007] Furthermore, the guide wheel has an annular groove structure in the middle, and a precision bearing is embedded in the middle of the guide wheel. Moreover, the precision bearing and the locating nut are threadedly connected to the lead screw at their axial centers.

[0008] Furthermore, the support pile includes a pile body, a fixing member, a bearing seat, a connecting angle plate, and a connecting pile. The fixing member is installed on the top of the pile body, and a bearing seat is installed inside between the pile body and the fixing member. The connecting angle plates are symmetrically connected on both sides of the connection between the pile body and the fixing member, and a connecting pile is connected in the middle of the side of the connecting pile away from the conveyor wheel.

[0009] Furthermore, the connecting angle plate is integrally formed with the pile body and the fixing component, and the pile body and the fixing component are structurally detachable, and the connecting pile and the pile body are welded together.

[0010] Furthermore, the adjustment frame includes a pressure rod, a rod sleeve, a bracket, and a damping shaft. The middle section surface of the pressure rod is fitted with a rod sleeve, and brackets are installed at both ends of the pressure rod. A damping shaft is horizontally installed at the end of the bracket away from the pressure rod.

[0011] Furthermore, the surfaces of the rod sleeve and the guide wheel are both processed using a polishing process, and the end of the damping shaft away from the bracket is connected and fixed to the connecting pile by bolts.

[0012] Furthermore, the movable seat includes a slider, a fixed angle plate, and a limiting bolt. The fixed angle plate is symmetrically installed on the top of the slider, and a limiting bolt is provided on the side of the fixed angle plate away from the vertical central axis of the slider.

[0013] Furthermore, the limiting bolt and the slider are connected by threads, and the slider and the guide rail are connected by a keyway structure. The slider and the fixed angle plate are connected by welding, and the two sides of the pile body are provided with groove structures that match the surface structure of one side of the fixed angle plate.

[0014] This utility model provides a sliver feeding device for a drawing frame, which has the following advantages:

[0015] 1. This utility model involves arranging and installing several conveying wheels on the surface of a lead screw. The guide wheels can be screwed onto the surface of the lead screw using a precision bearing in the middle. Then, limiting nuts are tightened on both sides of the precision bearing to confine the guide wheels to the surface of the lead screw. With the above structure, on the one hand, the V-shaped guide wheels can provide a guiding function for the conveyed cotton strips, while avoiding unnecessary interference between the cotton strips during the conveying process. On the other hand, the number of conveying wheels can be adjusted within a certain range according to the number of cotton strips to be conveyed, thereby ensuring the flexibility and adaptability of the device.

[0016] 2. This utility model features support piles installed at both ends of a lead screw. Each support pile has a detachable pile body and a fixing component, which, together with the bearing seat between them, allows the lead screw to be disassembled as needed to adjust the number of conveying wheels, thereby further ensuring the flexibility and convenience of the device. Furthermore, a movable seat is connected to the bottom of the support pile, and a guide rail is provided at the bottom of the movable seat. A keyway connection between the slider and the guide rail allows the support pile, connected to the lead screw and conveying wheels, to be moved horizontally along the surface of the guide rail. An appropriate number of support piles and lead screws can be installed according to the needs of conveying cotton strips to meet different conveying requirements. The pile body can be fixed to the slider via a fixing angle plate. When the slider needs to be limited, simply tighten the limiting bolt and press its lower end against the guide rail surface to prevent the slider from slipping.

[0017] 3. This utility model features an adjusting frame connected to one side of the support pile. The adjusting frame, using a damping shaft at the end furthest from the support and bolts, is fixed to the connecting pile on the side of the pile. The damping shaft's rotational nature allows for vertical adjustment of the pressure rod connected to it via the support, swinging it up and down at a certain angle. Combined with the sleeve on the pressure rod's surface, this provides tension to the cotton strip during transport and also confines it within the V-shaped groove of the guide wheel. This prevents the cotton strip from shifting during transport and detaching from the guide wheel, thus ensuring smooth transport. Furthermore, the polishing process of the guide wheel and sleeve minimizes wear on the cotton strip during transport, preventing any impact on its quality. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] like Figures 1 to 5As shown, a sliver feeding device for a drawing frame includes a lead screw 1 and conveyor wheels 2. Conveyor wheels 2 are arranged and mounted on the surface of the lead screw 1, and support posts 3 are installed at both ends of the lead screw 1. An adjusting frame 4 is connected to the side of the support post 3 away from the lead screw 1, and a movable seat 5 is installed at the bottom of the support post 3. A guide rail 6 is connected to the bottom of the movable seat 5. The conveyor wheel 2 includes a guide wheel 201, a precision bearing 202, and a limiting nut 203. The precision bearing 202 is installed at the axis of the guide wheel 201, and the precision bearing 202... Both sides of 02 are provided with limit nuts 203. The middle of the guide wheel 201 is provided with an annular groove structure, and the precision bearing 202 is embedded in the middle of the guide wheel 201. The axis of the precision bearing 202 and the limit nut 203 are threadedly connected to the lead screw 1. The guide wheel 201 can be screwed to the surface of the lead screw 1 using the middle precision bearing 202. Then, the limit nuts 203 are tightened on both sides of the precision bearing 202 to limit the guide wheel 201 to the surface of the lead screw 1.

[0026] like Figures 1 to 5 As shown, the support pile 3 includes a pile body 301, a fixing member 302, a bearing seat 303, a connecting angle plate 304, and a connecting pile 305. The fixing member 302 is installed on the top of the pile body 301, and a bearing seat 303 is installed inside the pile body 301 and the fixing member 302. The connecting angle plates 304 are symmetrically connected on both sides of the connection between the pile body 301 and the fixing member 302. A connecting pile 305 is connected to the middle of the side of the connecting pile 305 away from the conveyor wheel 2. The connecting angle plates 304 are integrally formed with the pile body 301 and the fixing member 302, and the pile body 301 and the fixing member 302 are structurally detachable. The connecting pile 305 is welded to the pile body 301. The movable seat 5 includes a slider 501, a fixing angle plate 502, and a limiting bolt 503. The slider 501... Fixed angle plates 502 are symmetrically installed on the top left and right sides. A limit bolt 503 is provided on the side of the fixed angle plate 502 away from the vertical central axis of the slider 501. The limit bolt 503 is threadedly connected to the slider 501. The slider 501 and the guide rail 6 are connected to each other by a keyway structure. The slider 501 and the fixed angle plate 502 are welded together. The two sides of the pile body 301 are provided with groove structures that match the surface structure of one side of the fixed angle plate 502. The support pile 3 has a detachable pile body 301 and a fixing part 302. With the bearing seat 303 between the two, the lead screw 1 can be disassembled as needed. By using the keyway connection between the slider 501 and the guide rail 6, the support pile 3, which is connected to the lead screw 1 and the conveying wheel 2, can be moved along the surface of the guide rail 6.

[0027] like Figures 1 to 5As shown, the adjustment frame 4 includes a pressure rod 401, a rod sleeve 402, a bracket 403, and a damping shaft 404. The rod sleeve 402 is fitted onto the middle section of the pressure rod 401, and the brackets 403 are installed at both ends of the pressure rod 401. The damping shaft 404 is horizontally installed at the end of the bracket 403 away from the pressure rod 401. The surfaces of the rod sleeve 402 and the guide wheel 201 are both polished. The end of the damping shaft 404 away from the bracket 403 is connected and fixed to the connecting pile 305 on the side of the pile body 301 by bolts. The entire adjustment frame 4 uses the end of the damping shaft 404 away from the bracket 403, in conjunction with the bolts, to connect and fix it to the connecting pile 305 on the side of the pile body 301. The structural rotation of the damping shaft 404 allows the pressure rod 401 connected to it by the bracket 403 to swing up and down at a certain angle in the vertical direction.

[0028] In summary, as Figures 1 to 5 As shown, when using the sliver feeding device of the drawing frame, firstly, according to the material feeding requirements, an appropriate number of guide rollers 201 are continuously and rapidly screwed through the threaded connection between the precision bearing 202 and the lead screw 1. During this period, a corresponding number of limit nuts 203 are placed on both sides of the guide rollers 201. By tightening the limit nuts 203 to both sides of the precision bearing 202, the guide rollers 201 are structurally limited.

[0029] After the conveying wheels 2 on the surface of the lead screw 1 are arranged and installed, the two ends of the lead screw 1 are respectively inserted and connected to the bearing seats 303. Then, the bearing seats 303 are embedded into the top of the pile body 301. Then, the fixing parts 302 and the pile body 301 are connected to each other, and the connecting angle plates 304 between the two are aligned with each other. Then, the bolts are used to connect and fix them.

[0030] Then, the bottom of the pile 301 is connected to the slider 501 connected to the fixed angle plate 502, and the fixed angle plate 502 is used in conjunction with the bolts to connect and fix the support pile 3 and the movable seat 5. As needed, the movable seat 5 at the bottom of the support pile 3 can be used to connect the lead screw 1 connected to the conveyor wheel 2 to the surface of the guide rail 6 with the required quantity of work.

[0031] During the cotton sliver conveying process, the damping shaft 404 connected to the connecting pile 305 on one side of the pile body 301 can be used to swing and adjust the support 403 connected thereto. This allows the pressure rod 401 connected to the support 403 to be adjusted synchronously, and the rod sleeve 402 on the surface of the pressure rod 401 to come into contact with the conveyed cotton sliver, thereby achieving the effect of structural tension. At the same time, it can also ensure that the cotton sliver conveyed by the guide wheel 201 is as confined as possible within the V-groove of the guide wheel 201, so as to ensure the uniformity and stability of the material conveying.
