Description
Technical Field
[0001] This utility model relates to the technical field of white filament production, and in particular to a feeding mechanism for high-grade white filament production. Background Technology
[0002] White filament, also known as white raw silk, is yarn obtained after silkworm cocoons are reeled. It is a type of raw silk and holds a unique position in the textile industry. It is the best and longest single thread drawn from the silkworm cocoon, and is the relatively neat and smooth silk from the middle of the cocoon layer, with higher quality. White raw silk is characterized by its softness, smoothness, full hand feel, good strength and elongation, elasticity, soft luster, and strong moisture absorption. It is also non-irritating to the human body and is a high-grade textile material. In the early stage of its production, the long filaments are extracted and screened from the silkworm cocoons before manufacturing. Therefore, the finished silk has uniform and delicate qualities, and the clothes will appear to have a more high-end texture and beautiful luster. At the same time, its flexibility and tensile strength are also stronger, and it is generally used in high-end clothing categories.
[0003] Feeding mechanisms are required in the production of white filaments. Traditional feeding mechanisms are not convenient for adjusting the spacing between multiple sets of white filaments, resulting in low practicality and poor stability in feeding white filaments. This can easily damage the white filaments during feeding, thus presenting certain drawbacks.
[0004] Therefore, in order to solve the above problems, this utility model provides a feeding mechanism for the production of high-grade white filament. Utility Model Content
[0005] The purpose of this invention is to provide a feeding mechanism for the production of high-grade white filament, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for producing high-grade white filament, comprising a support frame, a fixed plate installed at one bottom end of the support frame, a threaded rod installed on the support frame, a movable frame installed at the bottom of the threaded rod, a sliding rod installed between the inner sidewalls of the movable frame, several sets of sliders installed at equal intervals on the outer ring surface of the sliding rod, a support column installed at the bottom of the slider, and a limit tube installed at the bottom of the support column.
[0007] Preferably, the support frame is symmetrically equipped with fixing clips at both ends, the top of the fixing clip is equipped with a fastening bolt, the bottom of the fastening bolt extends through to the inside of the fixing clip and a limiting plate is installed, the fastening bolt is threadedly connected to the inside of the fixing clip, and the bottom of the limiting plate is equipped with an anti-slip pad.
[0008] Preferably, a throttle is installed at the top end of the threaded rod, the outer ring surface of the threaded rod is threadedly connected to the inside of the support frame, and the bottom of the threaded rod is rotatably connected to the top of the movable frame, and the outside of the movable frame is in contact with the outer side of the fixed plate.
[0009] Preferably, limit rods are symmetrically installed on the top of the movable frame and on both sides of the threaded rod. One end of the limit rod passes through the support frame and extends above its top. The outer ring surface of the limit rod is slidably connected to the inside of the support frame.
[0010] Preferably, the fixed plate has several sets of inclined grooves at equal intervals on its outer side, and the multiple sets of inclined grooves are distributed in a mirror image. The fixed column is installed on one side of the support column and inside the inclined groove.
[0011] Preferably, a through groove is provided at one bottom end of the limiting tube, a movable rod is installed at one top inner side of the limiting tube, a return spring is installed on the outer ring surface of the movable rod, a handle is installed at one top end of the movable rod after passing through the top of the limiting tube, and a semi-circular limiting ring is installed at one bottom end of the movable rod inside the through groove.
[0012] In summary, this utility model has the following beneficial technical effects:
[0013] This high-grade white filament production feeding mechanism, when the movable frame moves up and down, drives the support column to move together. Since the fixed column is in the inclined groove, it slides along the inclined groove during the up and down movement of the movable frame, causing the support column to move horizontally and the slider to slide on the slide rod, thereby changing the spacing of the limit tubes to adapt to the feeding needs of white filaments of different specifications. By pulling the handle upward, the operator moves the movable rod upward, which in turn moves the semi-circular limit ring upward. At this time, the return spring is compressed. After the white filament is placed into the limit tube, the handle is released. Under the elastic restoring force of the return spring, the movable rod and the semi-circular limit ring will move downward. The semi-circular limit ring limits the white filament to the bottom of the inner side of the limit tube, ensuring the stability of the white filament feeding. It is convenient to operate and has better practicality. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 - Figure 5 The present invention will be described in further detail below.
[0021] A feeding mechanism for producing high-grade white filament, referring to Figure 1 - Figure 5 It includes a support frame 1, a fixed plate 2 installed at one bottom end of the support frame 1, a threaded rod 3 installed on the support frame 1, a movable frame 4 installed at the bottom of the threaded rod 3, a sliding rod 5 installed between the inner side walls of the movable frame 4, several sets of sliders 6 installed at equal intervals on the outer ring surface of the sliding rod 5, a support column 7 installed at the bottom of the slider 6, and a limit tube 8 installed at the bottom of the support column 7.
[0022] Reference Figure 1 - Figure 3 The support frame 1 has symmetrically installed fixing clips 9 at both ends. The top of the fixing clip 9 is equipped with a fastening bolt 10. The bottom of the fastening bolt 10 extends into the inside of the fixing clip 9 and is equipped with a limiting plate 11. The fastening bolt 10 and the inside of the fixing clip 9 are threaded together. The bottom of the limiting plate 11 is equipped with an anti-slip pad 12. The fixing clips 9 are symmetrically installed at both ends of the support frame 1 to fix the entire feeding mechanism to other equipment or brackets. When the fastening bolt 10 is rotated, the fastening bolt 10 will move downward, thereby driving the limiting plate 11 to move downward. The downward movement of the limiting plate 11 will press the object inside the fixing clip 9 to fix the feeding mechanism. The anti-slip pad 12 is installed at the bottom of the limiting plate 11 to increase the friction between the limiting plate 11 and the fixed object, preventing the feeding mechanism from sliding during use and ensuring its stability.
[0023] Reference Figure 1 - Figure 2A handle 13 is installed at the top end of the threaded rod 3. The outer ring surface of the threaded rod 3 is threadedly connected to the inside of the support frame 1, and the bottom of the threaded rod 3 is rotatably connected to the top of the movable frame 4. The outside of the movable frame 4 is in contact with the outer side of the fixed plate 2. When the handle 13 is rotated, the threaded rod 3 rotates, and the threaded rod 3 moves up and down on the support frame 1. The bottom of the threaded rod 3 is rotatably connected to the top of the movable frame 4, so that the threaded rod 3 does not drive the movable frame 4 to rotate together during rotation, but converts the rotational motion into its own up and down movement, thereby driving the movable frame 4 to move up and down. The outer surface of the fixed plate 2 is in contact with the outer side to ensure the stability of the movable frame 4 during the up and down movement. Limiting rods 14 are symmetrically installed on the top of the movable frame 4 and on both sides of the threaded rod 3. One end of the limiting rod 14 passes through the support frame 1 and extends to its top. The outer ring surface of the limiting rod 14 is slidably connected to the inside of the support frame 1. When the threaded rod 3 drives the movable frame 4 to move up and down, the limiting rod 14 will slide up and down with the movable frame 4 in the support frame 1. The limiting rod 14 limits and guides the movement of the movable frame 4 to prevent the movable frame 4 from tilting or shaking during the movement.
[0024] Reference Figure 1 - Figure 4 The fixed plate 2 has several sets of inclined grooves 201 evenly spaced on its outer side. The multiple sets of inclined grooves 201 are distributed in a mirror image. A fixed column 15 is installed on one side of the support column 7 and inside the inclined groove 201. When the movable frame 4 moves up and down, it will drive the support column 7 to move together. Since the fixed column 15 is inside the inclined groove 201, the fixed column 15 will slide along the inclined groove 201 during the up and down movement of the movable frame 4, so that the support column 7 moves in the horizontal direction and the slider 6 slides on the slide rod 5, thereby changing the spacing of the limit tube 8 to adapt to the feeding requirements of white filaments of different specifications.
[0025] Reference Figure 5 A through groove 801 is provided at one bottom end of the limiting tube 8. A movable rod 16 is installed at the top inner side of the limiting tube 8. A return spring 17 is installed on the outer ring surface of the movable rod 16. A handle 18 is installed at the top end of the movable rod 16 after it passes through the top of the limiting tube 8. A semi-circular limiting ring 19 is installed at the bottom end of the movable rod 16 and inside the through groove 801. When it is necessary to put the white filament into the limiting tube 8, the operator pulls the handle 18 upward, which moves the movable rod 16 upward, and then moves the semi-circular limiting ring 19 upward. At this time, the return spring 17 is compressed. After the white filament is put into the limiting tube 8, the handle 18 is released. Under the elastic restoring force of the return spring 17, the movable rod 16 and the semi-circular limiting ring 19 will move downward. The semi-circular limiting ring 19 limits the white filament to the bottom inner side of the limiting tube 8, ensuring the stability of the white filament feeding.
[0026] The implementation principle of a feeding mechanism for high-grade white filament production according to this utility model embodiment is as follows: When using this mechanism, the fixing clamps 9 are symmetrically installed at both ends of the support frame 1 to fix the entire feeding mechanism to other equipment or brackets. When the fastening bolts 10 are rotated, the fastening bolts 10 will move downward, thereby driving the limiting plate 11 to move downward. The downward movement of the limiting plate 11 will press the object inside the fixing clamps 9 to fix the feeding mechanism. The anti-slip pad 12 is installed at the bottom of the limiting plate 11 to increase the friction between the limiting plate 11 and the fixed object, preventing the feeding mechanism from being used excessively. To ensure stability during the process, when the rotating handle 13 drives the threaded rod 3 to rotate, the threaded rod 3 will move up and down on the support frame 1. The bottom of the threaded rod 3 is rotatably connected to the top of the movable frame 4, so that the threaded rod 3 will not drive the movable frame 4 to rotate together during the rotation, but will convert the rotational motion into its own up and down movement, thereby driving the movable frame 4 to move up and down. The outside of the movable frame 4 is in contact with the outer side of the fixed plate 2, which can ensure the stability of the movable frame 4 during the up and down movement. When the threaded rod 3 drives the movable frame 4 to move up and down, the limit rod 14 will move accordingly. The movable frame 4 slides up and down within the support frame 1. The limiting rod 14 limits and guides the movement of the movable frame 4, preventing it from tilting or wobbling during movement. When the movable frame 4 moves up and down, it drives the support column 7 to move as well. Since the fixed column 15 is within the inclined groove 201, it slides along the inclined groove 201 during the up and down movement of the movable frame 4. This causes the support column 7 to move horizontally, while simultaneously causing the slider 6 to slide on the slide rod 5, thereby changing the spacing of the limiting tubes 8 to accommodate the feeding requirements of different specifications of white filament. When the white filament is placed into the limiting tube 8, the operator pulls the handle 18 upward, causing the movable rod 16 to move upward, which in turn causes the semi-circular limiting ring 19 to move upward. At this time, the return spring 17 is compressed. After the white filament is placed into the limiting tube 8, the handle 18 is released. Under the elastic restoring force of the return spring 17, the movable rod 16 and the semi-circular limiting ring 19 will move downward. The semi-circular limiting ring 19 limits the white filament to the bottom of the inner side of the limiting tube 8, ensuring the stability of the white filament feeding. The operation is convenient and the practicality is better. The external spiral opening angle of the threaded rod 3 and the fastening bolt 10 is 20 degrees, and the thread self-locking condition meets the following formula calculation: self-locking condition = friction coefficient * tan (spiral angle) ≥ 1.
