Description

Technical Field

[0001] The utility model relates to a spinning frame, in particular to a compact spinning device in a drafting system of a ring spinning frame. Background Art

[0002] As Figure 1 、 Figure 2 shown, the back roller rubber roller 6, middle roller rubber roller 4, and front roller rubber roller component 2 of the spinning frame are installed on the rocker 9. The back roller shaft 5, middle roller shaft 3, and front roller shaft 1 are installed on the roller pier 32. The rocker 9 is hinged to the roller pier 32 through the rocker holding rod 33 and the holding rod seat 34. As Figure 1 shown, the back roller shaft 5, middle roller shaft 3, and front roller shaft 1 rotate counterclockwise. Generally, the rotation speed of the middle roller shaft 3 is 1 - 2.5 times that of the back roller shaft 5, and the rotation speed of the front roller shaft 1 is 10 - 100 times that of the middle roller shaft 3. The roving is drafted and thinned and the yarn is conveyed to the mechanical compact spinning anti-twist rubber roller component 16. An agglomerating block 15 is arranged between the anti-twist rubber roller component 16 and the front roller rubber roller component 2. The front roller rubber roller component 2, the agglomerating block 15, and the anti-twist rubber roller component 16 are all attached to the cylindrical surface of the front roller shaft 1. The front roller rubber roller component 2 is pressed on the front roller shaft 1 by the pressure of the rocker 9. As Figure 1 、 Figure 2 shown, the pressure spring piece 13, the rocker leaf spring 12, and the rocker body 9 generate a rotational force centered on the axis of the front roller rubber roller component 2, so that the anti-twist rubber roller component 16 is closely attached to the front roller shaft 1. The rocker leaf spring 12 is fixed to the rocker body 9 by the rocker leaf spring pressing plate 11. A magnet is provided at the position where the agglomerating block 15 is close to the front roller shaft 1, so that the agglomerating block 15 is closely attached to the front roller shaft 1.

[0003] As Figure 1 、 Figure 2 、 Figure 3 shown, the yarn thinned by drafting is collected by the agglomerating block 15 after being output from the nip of the front roller shaft 1 and the front roller rubber roller component 2. The gathered fibers are output from the anti-twist rubber roller component 16 and then reach the yarn guide hook 36, and then are guided into the traveler on the ring 38. The traveler rotates around the spindle tube 37 to twist and form a compact spun yarn. Among them, the back roller shaft 5, middle roller shaft 3, and front roller shaft 1 rotate actively, and the back roller rubber roller 6, middle roller rubber roller 4, front roller rubber roller 2, and anti-twist rubber roller component 16 rotate passively.

[0004] The key to the drafting of the spinning frame is that all rubber rollers can run at a stable speed according to the set speed ratio. Any foreign matter adhesion on the surface of the rubber roller and the roller shaft will cause the running speed of the rubber roller to change, thus deteriorating the yarn quality. The most crucial point of mechanical compact spinning is that during the spinning process, the agglomerating block must be closely attached to the front roller shaft. Any detachment will cause the yarn quality to deteriorate.

[0005] As Figure 5 、Figure 6 As shown in the figure, in the spinning draft of the ring spinning frame, it is a process of turning roving into yarn. During this process, some short fibers will be scattered due to fiber breakage. At the same time, the fibers also contain foreign matters such as cotton wax and cotton candy. During the spinning process, there will be a certain amount of foreign matter adhesion on the rubber rollers, and there will also be foreign matter adhesion on the roller shaft 1. There will be foreign matter accumulation on the back of the gathering block 15. All these will lead to the deterioration of the quality of the mechanical compact spinning yarn.

[0006] As Figure 3 , Figure 4 , Figure 5 As shown, in the existing mechanical compact spinning gathering block 75, the surface close to the front roller rubber roller 2 is a straight surface. Some fibers spit out from the drafting nip formed by the front roller shaft 1 and the front roller rubber roller 2 will be blocked by this straight surface. As Figure 5 shown, the blocked fibers will accumulate between the front roller rubber roller and the gathering block. This accumulation will suddenly be taken away by the front roller shaft 1 at an uncontrollable time, resulting in the lifting of the gathering block 75 and the deterioration of the quality of a section of the yarn.

[0007] As Figure 6 shown, in the existing mechanical compact spinning gathering block 75, the surface close to the anti-twist rubber roller component 16 is a straight surface. Some fibers adhered to the anti-twist rubber roller component 16 will be blocked by this straight surface. The blocked fibers will accumulate between the anti-twist rubber roller component 16 and the gathering block 75. This accumulation will suddenly be taken away by the anti-twist rubber roller component 16 at an uncontrollable time, resulting in the lifting of the anti-twist rubber roller component 16 and the deterioration of the quality of a section of the yarn.

[0008] For the mating surface between the existing mechanical compact spinning gathering block 75 and the front roller shaft 1, if foreign matters adhere to the front roller shaft 1 in the areas close to both sides and the non-gathering groove area of the gathering block 75, the place where the gathering block 75 is close to the outlet of the gathering groove will leave the front roller shaft 1, and the disengagement will cause the deterioration of the yarn quality.

[0009] For the mating of the existing mechanical compact spinning gathering block 75 and the front roller shaft 1, the sliver moves and gathers between the surfaces of the gathering block 75 and the front roller shaft 1. It is impossible to judge whether there is foreign matter adhesion on the front roller shaft 1 and whether the fibers escape from the gathering groove. Summary of the Invention

[0010] The present invention provides a mechanical compact spinning gathering block that is beneficial to the stability of spinning in order to solve the above-mentioned deficiencies of the prior art.

[0011] The technical solution adopted by the present invention to solve the above deficiencies is as follows:

[0012] A mechanical compact spinning gathering block that is beneficial to the stability of spinning, and two inclined surfaces that form an oblique angle with the axis of the front roller shaft are arranged on the left and right sides of the gathering groove of the gathering block close to the drafting rubber roller.

[0013] Preferably, on both sides of the gathering groove of the gathering block, two outer bevel angles of 3-18 degrees are provided on the left and right near the drafting rubber roller, forming an angle with the axis of the front roller shaft, so that lint accumulation on the side of the gathering block close to the roller shaft is not easily formed, improving the spinning stability.

[0014] Preferably, a part of the material in the non-gathering groove area of the gathering block close to the front roller rubber roller is cut off, and two inclined surfaces are formed on the left and right of the gathering block, so that foreign matters adhered to the roller shaft are more easily carried away by the rotating roller shaft, making the spinning more stable.

[0015] Preferably, at one end of the gathering block close to the anti-twist rubber roller, indentations are provided on both sides of the gathering groove, so that the gathering groove is close to the anti-twist rubber roller, the floating area of the sliver is reduced, and at the same time, flying fibers or foreign matters at the part of the gathering block close to the anti-twist rubber roller can be carried away by the rotating roller shaft, reducing lint accumulation at the part of the gathering block close to the anti-twist rubber roller. Lint accumulation will cause the gathering block and the anti-twist rubber roller to deviate from the set position, affecting the spinning quality. Reducing lint accumulation can improve the spinning stability.

[0016] Preferably, at one end of the gathering block close to the anti-twist rubber roller, indentations of 0.5-3 mm are provided on both sides of the gathering groove, so that the gathering groove is close to the anti-twist rubber roller.

[0017] Preferably, for the solid body of the gathering block close to the anti-twist rubber roller component, except for the working area of the gathering groove, other parts are retracted away from the anti-twist rubber roller component, increasing the gap between the anti-twist rubber roller component and the gathering block. Without affecting the gathering function of the gathering block, the accumulation of waste lint between the gathering block and the anti-twist rubber roller component is reduced, which is beneficial to the stable spinning.

[0018] Preferably, a part of the solid body in the non-gathering groove working area of the contact surface between the gathering block and the roller shaft is cut off. When there are foreign matters adhered to the roller shaft, the probability of the foreign matters lifting the gathering block away from the surface of the roller shaft is reduced, which is beneficial to the stable spinning.

[0019] Preferably, some materials are cut off in the non-gathering groove working area, so that the contact surface between the gathering block and the roller shaft can be observed. An observation window is provided to directly see the working surface of the lower roller shaft under part of the gathering block during the operation of the machine, which can better judge whether there are foreign matters adhered to the roller shaft, whether the fibers escape from the gathering area during the spinning process, accurately judge the maintenance period, and is also beneficial to judge whether the gathering block leaves the front roller shaft.

[0020] Preferably, an observation window is opened between the contact surface of the gathering block and the roller shaft and the back surface of the gathering block, so that the cleaning condition of the surface of the lower roller shaft under the contact surface of part of the gathering block can be seen without lifting the cradle, which is beneficial to judging the maintenance period. At the same time, the influence of foreign matters adhered to the roller shaft on the position of the gathering block during the spinning process is reduced, making the spinning stable.

[0021] Compared with the prior art, the advantages of the present utility model are as follows: By optimizing the design of the gathering block, the adhesion of foreign matters and the influence of fibers on the position of the gathering block are reduced, the influence of foreign matter adhesion on the stable speed operation of the rubber roller is reduced, and the spinning is stabilized.

[0037] The present utility model will be further described below in conjunction with the attached drawings and embodiments.

[0038] As Figure 7 -17 shows, a gathering block 15 for mechanical compact spinning includes a gathering block main body. Two inclined surfaces 156 are provided at the position where the gathering block 15 is close to the front roller rubber roller 2. Without affecting the function of the gathering groove 151, the lower edge of the inclined surface 156 has a certain contact with the front roller shaft 1. When the front roller shaft 1 rotates, it pushes the waste cotton adhered to the front roller shaft 1 and the gathering block 15 to move towards the left and right sides of the gathering block 15, and finally leaves the working area of the gathering block, making the spinning stable.

[0039] As Figure 13 、 Figure 15 、 Figure 16 As shown, a part of the material at the position where the gathering block 15 is close to the anti - twist rubber roller component 16 is indented 157. Without affecting the function of the gathering groove 151, it can increase the space between the gathering block 15 and the anti - twist rubber roller component 16, reduce the influence of foreign object adhesion on the position of the gathering block 15 by the anti - twist rubber roller component 16 during the spinning process, and reduce the deterioration of the yarn index caused by the non - controllable shedding of the flying cotton accumulated on the back surface of the gathering block 15 and then being twisted into the yarn during the spinning process, making the spinning stable.

[0040] As Figure 15 、 Figure 16 As shown, the fitting surface 153 between the gathering block 15 and the roller shaft 1 leaves a certain distance from the roller shaft 1 in the non - gathering groove 151 working area, forming a surface 158, which reduces the influence of foreign object adhesion on the position of the gathering block 15 by the roller shaft 1 during the spinning process, making the spinning stable.

[0041] As Figure 15 、 Figure 16 As shown, the fitting surface 153 between the gathering block 15 and the roller shaft 1, and the opposite side of the fitting surface 153 is the back surface 154 of the gathering block. An observation window 155 is opened between the fitting surface 153 and the back surface 154 of the gathering block. It is possible to see the cleaning condition of the surface of the roller shaft 1 under the fitting surface 153 of part of the gathering block without lifting the cradle 9, which is beneficial for judging the maintenance period. At the same time, it reduces the influence of foreign object adhesion on the position of the gathering block 15 by the roller shaft 1 during the spinning process, making the spinning stable, and judging whether the fibers escape from the gathering area during the spinning process.
