Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment, and more particularly to the field of drawing frame technology, specifically a drawing frame coiling device. Background Technology

[0002] A drawing frame is a type of textile machinery primarily used to improve the internal structure of slivers (long slivers of yarn, cotton, etc.), increase the uniformity of long segments, reduce weight unevenness, straighten and parallel the fibers in the sliver, reduce hooks, ensure the fineness meets specifications, and uniformly blend different types or qualities of raw materials to achieve the specified blending ratio. The coiling device is an important component of the drawing frame. Its main function is to evenly and neatly wind the fiber sliver, after drafting and mixing by the drawing frame, into the sliver can for use in subsequent spinning processes.

[0003] In a published Chinese patent application (publication number CN220846395U), titled "Ringing Chassis Transmission System and Drawing Frame," the ringing chassis transmission system includes two ringing chassis transmission mechanisms. These mechanisms respectively drive the left and right rings and the chassis. In other words, the two mechanisms are independent and do not interfere with each other. If one mechanism malfunctions and stops automatically, the other can continue operating without requiring the entire ringing chassis transmission system to stop, meaning the drawing frame can continue production without a complete shutdown. This results in low downtime and high practicality. Similarly, adjusting the ring tension does not require stopping the entire ringing chassis transmission system; only the corresponding ringing chassis transmission mechanism needs adjustment. While this prior art can wind the sliver into the sliver can, it has certain limitations in practical implementation.

[0004] In practical implementation, this existing technology (see attached) Figure 7 As the coiler 16 rotates, the swab spirals down into the swab container. The coiler remains above the swab container, and the height between the coiler and the bottom wall of the swab container is constant. The coiler's rotation causes the swab to spin and fall in a spiral. Due to the significant height difference, the gap between the swab coil section near the bottom wall of the swab container and the inner wall of the swab container is relatively large (see attached diagram). Figure 7 In the attached diagram, the distance between the dashed line at point A and the inner wall of the tampon tub is shown. The distance between the tampon coil section furthest from the bottom wall of the tampon tub and the inner wall of the tampon tub is relatively small (see attached diagram). Figure 7 In the attached diagram, the distance between the dashed line at point B and the inner wall of the tampon tub is shown. This results in a large gap between the tampon loop and the wall of the tampon tub, which reduces the amount of tampon the tub can hold. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a coiling device for a drawing frame, which solves the problems mentioned in the background section.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a coiling device for a drawing frame, which is installed on the drawing frame and includes a crossbeam, two sliver canisters, and two coiling components. The two ends of the crossbeam are fixedly installed to the drawing frame. Both coiling components are installed on the crossbeam, and the two sliver canisters are respectively located below the two coiling components. Each coiling component includes a telescopic member, a support plate, a cylinder, a servo motor, and a coiling disc. The telescopic member is fixedly installed on the crossbeam, and the support plate is fixedly installed at the output shaft end of the telescopic member. The cylinder passes through the support plate and the two are rotatably connected. The coiling disc is fixedly installed at the lower end of the cylinder. The servo motor is fixedly installed on the lower surface of the support plate, and the output shaft of the servo motor is drively connected to the cylinder, driving the cylinder to rotate. The telescopic member drives the support plate to rise or fall, and the support plate drives the coiling disc to rise or fall through the cylinder. After falling, the coiling disc is located inside the sliver canister.

[0009] Optionally, the coil component further includes a fixing block, a second gear, and a first gear. The fixing block is fitted onto the outer wall of the cylinder and the two are fixedly connected. The lower end of the fixing block is coaxially fixedly installed with the coil disc. The second gear is fitted onto the outer wall of the cylinder and the two are fixedly connected. The first gear is fixedly installed on the output shaft end of the servo motor, and the first gear meshes with the second gear.

[0010] Optionally, the coil component further includes a coil tube, which is curved in shape. One end of the coil tube obliquely penetrates the wall at the periphery of the coil disc and the two are fixedly connected. The other end of the coil tube passes through the fixing block and the cylinder in sequence. The coil tube communicates with the internal cavity of the cylinder, and the upper end of the cylinder is trumpet-shaped.

[0011] Optionally, the ring bar component further includes a guide rod, the upper middle part of which passes through the crossbeam and the two are slidably connected, and the lower end of the guide rod is fixedly connected to the support plate.

[0012] Optionally, the telescopic component may be a servo electric cylinder or an electric push rod.

[0013] (III) Beneficial Effects

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

[0015] This type of coiling device for a drawing frame, through the coordinated arrangement of the coiling component, sliver canister, and crossbeam, enables the effective winding of sliver within the sliver canister. The sliver passes through the coiling tube and slides down within it. A servo motor drives the cylinder to rotate, which in turn drives the coiling disc to rotate. As the disc rotates, it swings the sliver, causing it to descend in a spiral shape. Upon contact with the bottom, the sliver forms a coil, thus completing the winding of the sliver into the sliver canister. A telescopic component drives a support plate to rise or fall, which in turn drives the coiling disc to rise or fall via the cylinder. After descending, the coiling disc is positioned inside the sliver canister, reducing the height difference between the coiling disc and the bottom of the sliver canister. This ensures that the sliver descends in a spiral shape while maintaining sufficient force at the bottom to adhere tightly to the canister wall, preventing a large gap between the sliver and the canister and allowing the canister to properly accommodate the loaded sliver.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0027] Please see Figures 1 to 6 The present invention provides a technical solution: a sliver coiling device for a drawing frame, which is installed on the drawing frame and includes a cross frame 4, two sliver cans 1, and two sliver coiling components. The two ends of the cross frame 4 are fixedly installed on the drawing frame, and the two sliver coiling components are installed on the cross frame 4. The two sliver cans 1 are respectively located below the two sliver coiling components.

[0028] The present technical solution describes a coiling device for a drawing frame, installed on the drawing frame to wind sliver 5 from the drawing frame and place it into a sliver can 1. The sliver can 1 holds the sliver 5. The coiling device is used to wind the sliver and place it into the sliver can 1. The drawing frame includes a base plate 3 and a support plate 2. The support plate 2 is rotatably mounted on the base plate 3, and the sliver can 1 is placed on the support plate 2. Rotation of the support plate 2 causes the sliver can 1 to rotate.

[0029] The coiling component includes a telescopic component 6, a support plate 9, a cylinder 15, a servo motor 10, and a coiling disc 8. The telescopic component 6 is fixedly mounted on the crossbeam 4. The support plate 9 is fixedly mounted on the output shaft end of the telescopic component 6. The cylinder 15 passes through the support plate 9 and the two are rotatably connected. The coiling disc 8 is fixedly mounted on the lower end of the cylinder 15. The servo motor 10 is fixedly mounted on the lower surface of the support plate 9, and the output shaft of the servo motor 10 is connected to the cylinder 15 for transmission. The servo motor 10 drives the cylinder 15 to rotate. The telescopic component 6 drives the support plate 9 to rise or fall. The support plate 9 drives the coiling disc 8 to rise or fall through the cylinder 15. After falling, the coiling disc 8 is located inside the sliver canister 1.

[0030] The servo motor 10 drives the cylinder 15 to rotate on the support plate 9, and the rotation of the cylinder 15 drives the coiling disc 8, which is fixedly connected to it, to rotate. The telescopic component 6 drives the support plate 9 to move up and down. When the support plate 9 descends, it drives the cylinder 15 to descend, and the cylinder 15 can drive the coiling disc 8 to descend. After descending, the coiling disc 8 can be located inside the swab canister 1, thereby reducing the distance between the coiling disc 8 and the bottom of the swab canister 1, that is, reducing the height difference during the descent of the swab.

[0031] Specifically, the coiling component also includes a fixing block 13, a second gear 12, and a first gear 11. The fixing block 13 is fitted onto the outer wall of the cylinder 15 and the two are fixedly connected. The lower end of the fixing block 13 is coaxially fixedly installed with the coiling disc 8. The second gear 12 is fitted onto the outer wall of the cylinder 15 and the two are fixedly connected. The first gear 11 is fixedly installed on the output shaft end of the servo motor 10, and the first gear 11 meshes with the second gear 12.

[0032] The fixing block 13 is used to strengthen the connection between the cylinder 15 and the coiled disc 8. After the servo motor 10 is started, it drives the first gear 11 to rotate, the first gear 11 drives the second gear 12 meshing with it to rotate, and the second gear 12 drives the cylinder 15 to rotate, so that the cylinder 15 can rotate on the support plate 9.

[0033] More specifically, the coil component also includes a coil tube 14, which is curved in shape. One end of the coil tube 14 is inclined and passes through the wall at the periphery of the coil disc 8 and the two are fixedly connected. The other end of the coil tube 14 passes through the fixing block 13 and the cylinder 15 in sequence. The coil tube 14 is connected to the internal cavity of the cylinder 15, and the upper end of the cylinder 15 is trumpet-shaped.

[0034] The sliver 5 passes sequentially through the bobbin 15 and the coiling tube 14. The drawing frame moves the sliver 5, which slides down through the bobbin 15 and the coiling tube 14. When the bobbin 15 drives the coiling disc 8 to rotate, the coiling disc 8 rotates and swings the sliver 5, causing it to descend in a spiral shape. After touching the bottom, the sliver 5 forms a stacked spiral coil, thus completing the winding and placement of the sliver 5 into the sliver can 1 (reference). Figure 1 , Figure 2 As the cotton strips 5 are spirally stacked from bottom to top, they gradually rise higher. At this time, the support plate 9 is driven to rise by the telescopic component 6. The support plate 9 drives the coiling disc 8 to rise gradually through the cylinder 15, so that a certain distance is maintained between the coiling disc 8 and the cotton strips 5 after they touch the bottom, avoiding the distance being too large or too small.

[0035] Specifically, the ring bar component also includes a guide rod 7, the upper middle part of which passes through the crossbeam 4 and the two are slidably connected, and the lower end of the guide rod 7 is fixedly connected to the support plate 9.

[0036] Among them, the guide rod 7 plays a guiding role for the support plate 9, so as to prevent the support plate 9 from shifting laterally during the lifting and moving process.

[0037] Specifically, the telescopic component 6 includes, but is not limited to, a servo electric cylinder or an electric push rod. Other telescopic devices may also be used depending on actual production needs.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
