Description
Technical Field
[0001] The utility model relates to the technical field of carbon fiber cloth spinning machines, in particular to a drafting structure of a carbon fiber cloth spinning machine. Background Art
[0002] Carbon fiber cloth is mainly used for tensile, shear and seismic reinforcement of structural components. This material can be used together with the matching impregnated glue to become a carbon fiber composite material, which can constitute a complete carbon fiber cloth sheet reinforcement system. It is suitable for dealing with increased building loads, changes in engineering functions, material aging, concrete strength grades lower than the design value, structural crack treatment, and reinforcement projects for repair and protection of components serving in harsh environments. The warp tension frame is a mechanism used to press and stretch the warp in the production process of carbon fiber cloth, so that the warp is in a relative tension state. In the weaving process of carbon fiber cloth, the tension of the carbon fiber yarn needs to be controlled, and the carbon fiber yarn is pulled down from the yarn wheel. The warps are arranged in parallel to form warps. The weaving process requires that the tension of the warps is uniform, otherwise the cloth surface will be uneven and the surface density will be uneven. The drafting of the warps is mainly handled by installing two floating tension rollers on one side of the loom and staggering the warps on the outer surfaces of the two floating tension rollers. However, since the two floating tension rollers are fixed, when the warp feeding is uneven, it is easy to cause inconsistent yarn tension and uneven tension on the woven cloth surface, which leads to the problem of imperfect treatment of the method of installing two floating tension rollers on one side of the loom and staggering the warps on the outer surfaces of the two floating tension rollers. For this reason, we proposed a drafting structure for a carbon fiber cloth spinning machine. Utility Model Content

[0011] The utility model has the following beneficial effects:
[0012] 1. The drafting structure of the carbon fiber cloth spinning machine enables the transmission bracket to move under the push of the limiting column, and then drives the drafting roller to move through the adjusting plate, so that the position of the drafting roller can be adjusted to change the traction force of the warp, so that the warp can be adjusted in time when its traction force is too large or too small, thereby ensuring the quality of its carbon fiber cloth production.

[0014] 3. The drafting structure of the carbon fiber cloth spinning machine, when the driving thread column is rotated, the abutment rod is blocked by the fixed frame of the traction mechanism, so that the driving thread column and the abutment rod can move relative to each other, and then under the action of the first spring force, pressure can be given to the driving thread column, thereby increasing the friction force of the thread between the driving thread column and the fixed frame of the traction mechanism, making its fixation more stable.

[0024] See also Figures 1 to 7A drafting structure of a carbon fiber cloth spinning machine includes a traction mechanism fixed frame 1 and a warp 6. A drafting roller 4 for drafting the warp 6 is connected to the traction mechanism fixed frame 1. The warp 6 can be drafted by the drafting roller 4. Both sides of the traction mechanism fixed frame 1 are provided with a limiting slide groove 5. One end of the drafting roller 4 extends into the limiting slide groove 5 and is movably connected thereto. Under the limitation of the limiting slide groove 5, the adjustment movement of the drafting roller 4 is more stable. An adjusting plate 7 is movably sleeved at one end of the drafting roller 4. Under the limitation of the adjusting plate 7, the drafting roller 4 can be rotated at a fixed position on the adjusting plate 7, and driven by the adjusting plate 7, the drafting roller 4 can be moved. The position of the drafting roller 4 can be adjusted, and its adjusting plate 7 is in a cross shape. The middle of the adjusting plate 7 is connected to the inner side of the traction mechanism fixed frame 1 through a rotating shaft, so that the adjusting plate 7 can be rotated in a fixed position on the traction mechanism fixed frame 1. The warp 6 passes through the drafting roller 4 in a Z shape, and a line-fixing groove is opened on the drafting roller 4, so that the warp 6 can be arranged separately to avoid the entanglement of the warp 6. At the same time, a limiting seat 11 is movably connected in the line-fixing groove. Under the limitation of the line-fixing groove, the limiting seat 11 can move along a fixed trajectory, giving the warp 6 a movable space for automatic adjustment, and the limiting seat 11 is in contact with the warp 6.
[0025] See also Figures 1 to 3 The top end of the adjusting plate 7 is connected to the transmission bracket 8 through an axle pin, forming a hinge structure with the axle pin as the rotating axis, so that the adjusting plate 7 and the transmission bracket 8 can move relative to each other, and under the push of the transmission bracket 8, the adjusting plate 7 can rotate. The top end of the transmission bracket 8 is connected to the limiting column 2 through the rotating axis, forming a hinge structure with the axle pin as the rotating axis, so that the limiting column 2 and the transmission bracket 8 can move relative to each other, and under the push of the limiting column 2, the transmission bracket 8 can rotate.
[0026] See also Figures 1 to 3 The top of the limiting column 2 passes through the top of the traction mechanism fixed frame 1 and is movably connected thereto. The limiting column 2 is square. Under the limitation of the traction mechanism fixed frame 1, the limiting column 2 can move along a fixed track.
[0027] See also Figures 1 to 3 A connecting rod 9 is fixedly connected between the limiting columns 2. Driven by the connecting rod 9, the limiting column 2 can move. A driving threaded column 3 is movably sleeved on the top of the middle of the connecting rod 9. Under the limitation of the connecting rod 9, the driving threaded column 3 can be rotated at a fixed position on the connecting rod 9.
[0028] See also Figures 1 to 4 and Figure 6The driving threaded column 3 is threadedly mounted on the top of the traction mechanism fixed frame 1, and then the driving threaded column 3 is rotated to enable the driving threaded column 3 to push the connecting rod 9 to move. The top of the driving threaded column 3 passes through the traction mechanism fixed frame 1 and a through groove is provided in the middle of the driving threaded column 3. An abutment rod 10 is movably connected in the through groove. Under the limitation of the through groove, the limiting column 2 can move along a fixed track.
[0029] See also Figures 1 to 4 and Figure 6 The bottom of the abutment rod 10 contacts the top of the traction mechanism fixed frame 1, and then when the driving threaded column 3 moves, the abutment rod 10 can move relative to the driving threaded column 3, and a first spring 12 is fixed in the middle of the top of the abutment rod 10, and the top of the first spring 12 is fixed to the top of the through groove. Under the action of the elastic force of the first spring 12, pressure can be applied to the driving threaded column 3, thereby increasing the friction force of the thread between the driving threaded column 3 and the traction mechanism fixed frame 1, making its fixation more stable.
[0030] See also Figures 1 to 4 and Figure 6 The outer side of the limit seat 11 is a concave arc, so that the contact between the limit seat 11 and the warp 6 is more appropriate, and a second spring 13 is fixed on the inner side of the limit seat 11, and one end of the second spring 13 is fixed to the stretching roller 4. Under the action of the elastic force of the second spring 13, the limit seat 11 can contact with the warp 6, so that it can be automatically adjusted.
[0031] In summary, when the drafting structure of the carbon fiber cloth spinning machine is in use, when the spinning machine is running, the warp 6 is alone in the fixed line groove and contacts the limit seat 11. When the warp 6 is loose, the driving thread column 3 is rotated to move the driving thread column 3. At this time, the first spring 12 is compressed, so that the driving thread column 3 is given a limited force through the abutment rod 10, thereby increasing the friction force of the thread between the driving thread column 3 and the traction mechanism fixing frame 1, so that the fixation is more stable, and under the push of the driving thread column 3, the connecting rod 9 can Move, and then the limiting column 2 can move, driven by the limiting column 2, the transmission bracket 8 is rotated, and then the adjusting plate 7 is pushed to rotate, and driven by the adjusting plate 7, the position of the stretching rollers 4 is adjusted, thereby changing the traction force of the stretching rollers 4 on the warp 6, so that the warp 6 can be in a taut state, and under the action of the elastic force of the second spring 13, the limiting seat 11 can contact with the warp 6, so that when the warp 6 is too taut, it is given automatic adjustment space, so that its stretching traction force is more stable.
