Description

Technical Field

[0001] The present application relates to the technical field of spinning frame drafting, and in particular to a drafting device of a spinning frame. Background Art

[0002] Spinning frame is a spinning machine that stretches, twists and winds semi-finished roving or slivers into spun yarn during the spinning process. The slivers are stretched and twisted on the roving frame to make roving, the combing machine combs the fibers to make combed slivers, the gill carding machine combines the slivers, and the needle row stretching improves the sliver structure. The roving is further twisted and spun into spun yarn on the ring spinning frame. The spinning frame is the main machine for spinning. When the spinning frame produces spun yarn, the spun yarn needs to be drafted.

[0003] In an existing spinning frame, when the spinning frame is in use, the drafting device drafts the yarn through a plurality of upper and lower drafting rollers. Since the spacing between the upper and lower drafting rollers is fixed, the upper and lower drafting rollers in the drafting device can only draft yarns of the same thickness. Since the thickness of the yarns varies, if the spinning frame needs to draft a thicker yarn, the drafting device cannot draft it. Therefore, those skilled in the art provide a drafting device for a spinning frame to solve the problems raised in the above background technology. Utility Model Content

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-6 This application is described in further detail.

[0026] The embodiment of the present application discloses a drafting device of a spinning frame. Figure 1-6 The cam 2 is connected with the support plate 3 on one side of the cam 2 and the support plate 3 on the other side.

[0027] In this way, during the implementation process, when it is necessary to stretch the yarn in the spinning frame, the staff will start the spinning frame body 1, and the yarn at the outlet end of the spinning frame body 1 will pass through multiple sets of rollers 5. When the yarn passes through multiple sets of rollers 5, multiple sets of rollers 5 support the yarn, which has a stretching effect on the yarn. Multiple sets of rollers 5 are supported by fixed shafts 4, and the fixed shaft 4 is supported by brackets 2 and support plates 3. The yarn will contact multiple sets of rollers 5 and guide rollers 8, and the lifting assembly 6 adjusts the height of the rotating shaft 7. During the height adjustment of the rotating shaft 7, the gear disk 9 at one end engages with the surface of the rack 31, and the gear disk 9 drives the rotating shaft 7 to rotate. During the rotation of the rotating shaft 7, it drives the guide roller 8 to rotate. The guide roller 8 will stretch the surface of the yarn during the rotation, thereby improving the stretching effect of multiple sets of rollers 5.

[0028] Among them, multiple groups of rollers 5 are symmetrically arranged up and down, one side of the guide roller 8 is inclined and extends downward to the side where the two groups of rollers 5 are close to each other, and one side of the guide roller 8 protrudes outward between the two groups of rollers 5. When the yarn passes through the guide roller 8, the one side of the guide roller 8 fits the yarn, and by changing the distance between one side of the guide roller 8 and the roller 5, the outer surface of the yarn is supported, thereby increasing the stretching effect.

[0029] Preferably, the gear plate 9 has symmetrical limiting grooves 91 formed inside, and the upper and lower parts of the rotating shaft 7 are fixedly connected with clamping blocks 71. The two sets of clamping blocks 71 are respectively located inside the symmetrical limiting grooves 91 and fit against the inner wall of the gear plate 9.

[0030] The two sides of the limiting groove 91 are through grooves. The staff slides the gear plate 9 along the outer wall of the rotating shaft 7 so that the gear plate 9 is sleeved on the surface of the rotating shaft 7. When the rotating shaft 7 is inserted into the gear plate 9, the two sets of blocks 71 are located inside the limiting groove 91 and slide. The outer wall of the block 71 fits with the inner wall of the gear plate 9. During the rotation process, the gear plate 9 drives the rotating shaft 7 to rotate through the block 71, thereby improving the stability of the rotating shaft 7 during the rotation process.

[0031] Specifically, the lifting assembly 6 includes sliders 61 that slide inside the bracket 2 and the support plate 3. Two sets of sliders 61 are sleeved on the two side surfaces of the rotating shaft 7. The interiors of the two sets of sliders 61 are threadedly inserted with threaded shafts 62. One end of the two sets of threaded shafts 62 is rotatably inserted with the support plate 3. A turntable 66 is fixedly connected to the top of one of the threaded shafts 62.

[0032] The two groups of sliders 61 slide close to the inner walls of the bracket 2 and the support plate 3 respectively. The two groups of sliders 61 support the rotating shaft 7. The staff rotates the turntable 66, and the turntable 66 drives the threaded shaft 62 to rotate. One end of the threaded shaft 62 is inserted into the interior of the bracket 2 and a bearing ring is installed at the connection to reduce friction. During the rotation of the threaded shaft 62, the slider 61 is driven to rise and fall through the thread. During the lifting process of the slider 61, the position of the rotating shaft 7 is changed, which facilitates the adjustment of the height of the guide roller 8.

[0033] More specifically, the surfaces of the two sets of threaded shafts 62 are sleeved with first bevel gears 63, and the two sets of first bevel gears 63 are both located above the support plate 3. A connecting rod 64 is provided above the support plate 3, and both ends of the connecting rod 64 are fixedly connected to second bevel gears 65. The two sets of second bevel gears 65 are respectively meshed with the two sets of first bevel gears 63;

[0034] The first bevel gear 63 rotates along with the threaded shaft 62, and the two sets of second bevel gears 65 are linked by a connecting rod 64, so that the rotation frequency of the two sets of first bevel gears 63 is consistent. When the worker rotates the turntable 66, the rotation frequency of the two sets of threaded shafts 62 is consistent through the rotation of the connecting rod 64, the second bevel gear 65 and the first bevel gear 63. The threaded shaft 62 drives the slider 61 to rise and fall, so that the horizontal heights on both sides of the rotating shaft 7 and the guide roller 8 are consistent, which is convenient for stretching the spun yarn.

[0035] Furthermore, during the implementation process, support blocks 67 are symmetrically sleeved on the surface of the connecting rod 64. The lower parts of the two groups of support blocks 67 are fixedly connected to the upper outer wall of the support plate 3. Bearing rings are installed inside the support blocks 67. The bearing rings are fixed to the surface of the connecting rod 64 to reduce the friction between the connecting rod 64 and the support blocks 67. The support blocks 67 fix the connecting rod 64 horizontally above the support plate 3, thereby increasing the stability of the connecting rod 64 during rotation.

[0036] The implementation principle of the drafting device of a spinning frame in an embodiment of the present application is as follows: when in use, the yarn at the outlet end of the spinning frame body 1 will pass through multiple sets of rollers 5. When the yarn passes through the multiple sets of rollers 5, the multiple sets of rollers 5 support the yarn and have a stretching effect on the yarn. The multiple sets of rollers 5 are supported by the fixed shaft 4, and the fixed shaft 4 is supported by the bracket 2 and the support plate 3. The yarn will contact the multiple sets of rollers 5 and the guide roller 8. The lifting component 6 adjusts the height of the rotating shaft 7. During the height adjustment process of the rotating shaft 7, the gear disk 9 at one end engages with the surface of the rack 31, and the gear disk 9 drives the rotating shaft 7 to rotate. During the rotation of the rotating shaft 7, it drives the guide roller 8 to rotate. The guide roller 8 will stretch the surface of the yarn during the rotation process, thereby improving the stretching effect of the multiple sets of rollers 5.
