Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to an air-spinning impurity removal device. Background Art

[0002] Air-jet spinning is a new spinning technology that utilizes air flow to condense and twist fibers in a high-speed rotating spinning cup to form yarn. When in use, the sliver fiber raw material is fed in from the feeding port, and the sliver fiber raw material is grabbed and combed by the combing roller to disperse it into fiber filaments and throw it out. The fiber filaments are twisted by the spinning cup to connect with the yarn drawing head to form yarn, and the yarn twisted from the fiber filaments is drawn out through the yarn drawing head and finally wound by the winding roller.

[0003] The air-jet spinning mechanism is simple and can double the output of fine yarn. However, the spinning workshop will produce dust, cotton wool and other impurities floating in the air and adhering to the surface of the yarn roll, causing the impurities to be mixed into the yarn roll when the yarn is wound, affecting the hygiene and use of the yarn. Now an air-jet spinning impurity removal device is provided, which can effectively clean the impurities on the surface of the yarn.

[0004] Chinese patent CN218452422U discloses an air-spinning impurity removal device, including an air collecting hood, a placement slot is provided on the surface of the air collecting hood, a sliding roller and a brush plate are provided at one end of the air collecting hood, and a slider is provided on the side of the air collecting hood; an impurity removal box is provided inside the placement slot, a filter screen is provided at one end of the interior of the impurity removal box, and a handle is provided on the surface of the impurity removal box; a mounting frame is provided on the side of the air collecting hood, and a sliding slot is provided on the surface of the mounting frame. The above utility model has the following beneficial effects: the brush plate cleans the yarn on the surface of the winding roller to make the impurities on the surface of the yarn fall off, the fan sucks the impurities into the interior of the impurity removal box through the air collecting hood, and the rebound force of the supporting spring makes the sliding roller and the brush plate always fit with the yarn roll. When the impurities in the impurity removal box are collected a lot, the impurity removal box can be lifted out of the placement slot by the handle to clean the interior of the impurity removal box, thereby avoiding the problem that the impurities are mixed into the yarn roll when the yarn is wound, which affects the subsequent use of the yarn.

[0005] However, the above patent documents still have defects in the implementation process:

[0006] When the brush plate cleans the yarn on the surface of the winding roller, it can only clean the outer surface of the yarn close to the brush plate, and the inner surface of the yarn cannot be cleaned, so the cleaning effect is low. Utility Model Content

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] like Figure 1 and Figure 2 As shown, an air-spinning impurity removal device comprises two shells 1, the lower ends of the two shells 1 are fixedly connected with cubic support legs, the upper ends of the two shells 1 are commonly connected with a shell 2, a dust collecting device 3 is commonly fixedly connected between the opposite surfaces of the two shells 1, an inner cleaning device 4 is rotatably connected to the right side of the inside of the shell 2, an outer cleaning device 7 is rotatably connected to the left side of the inside of the shell 2, a yarn winding assembly 5 is rotatably connected to the front of the inner cleaning device 4, a yarn feeding assembly 6 is fixedly connected to the right side of the upper end of the shell 2, a discharge winding device 9 is fixedly connected to the rear end of the upper end of the shell 2, and the yarn feeding assembly 6 is located on the left side of the discharge winding device 9, and a protective shell 8 is commonly fixedly connected to the rear ends of the two shells 1 and the shell 2;

[0031] First, the yarn ends are fastened to the yarn winding assembly 5 through the yarn feeding assembly 6. The yarn feeding assembly 6 makes the yarn to be cleaned move back and forth and then winds the entire yarn winding assembly 5. During the above process, the inner cleaning device 4 rotates to clean the inner surface of the yarn, and the outer cleaning device rotates 7 to clean the outer surface of the yarn. After cleaning, the inner cleaning device 4 is closed, the yarn ends are untied and then fastened to the discharge winding device 9, and the yarn is taken out;

[0032] During the cleaning process, impurities such as dust and grass clippings on the yarn will fall or float inside the shell 2, and the dust suction device 3 will suck in and collect these impurities for unified removal during maintenance.

[0033] Specifically, in order to realize the function of the dust collecting device 3 to absorb impurities, please refer to Figure 3 In this solution, the dust collecting device 3 includes a square tube 32, the top of the inner side of the square tube 32 is fixedly connected with an air suction plate 31 by a thread, the upper part of the inner side of the square tube 32 is fixedly connected with a sealing plate 1 33, the center of the sealing plate 1 33 is fixedly connected with a fan casing 34, a fan is arranged in the fan casing 34, a ventilation duct 35 is fixedly connected to the lower end of the fan casing 34, one end of the ventilation duct 35 is connected to the fan output end and the other end is fixedly connected with a sealing plate 2 36, and the outer side of the sealing plate 2 36 is fixedly connected to the inner side of the square tube 32, a filter layer 37 is placed at the lower part of the sealing plate 2 36, and the filter layer 37 is located at the lower part of the sealing plate 2 36, and the bottom of the inner side of the square tube 32 is fixedly connected with an exhaust plate 38 by a thread;

[0034] The sealing plate 1 33 allows the air above the sealing plate 1 33 inside the square tube 32 to enter the fan only from the air inlet of the fan housing 34, thereby allowing the dust and other impurities inside the housing 2 to enter the fan through the air intake plate 31. The air intake plate 31 has a number of rectangular holes, which can prevent large impurities from entering the fan and damaging the equipment. At the same time, the air intake plate 31 also prevents personnel from being injured by the fan when opening the cover of the housing 2 for operation.

[0035] When dust and other impurities are sucked into the fan, the fan runs at a high speed and the lower part is close to a vacuum. Under the action of the pressure difference, the dust is sucked in and discharged from the ventilation duct 35 into the lower part of the sealing plate 2 36. The sealing plate 2 36 prevents the discharged impurities from floating into the upper space of the sealing plate 2 36 in the square tube 32. Further, the dust enters the filter layer 37. Since the filter layer 37 is a multi-layer mesh structure, dust and other impurities are deposited on the filter layer 37. There are several rectangular holes on the exhaust plate 38, and the filtered air is finally discharged through the exhaust plate 38.

[0036] Specifically, in order to realize the function of the yarn winding assembly 5 to perform winding and rotation after the yarn is fed, please refer to Figure 4 The yarn winding assembly 5 includes two annular shells 51, the inner surfaces of the two annular shells 51 are rotatably connected to the follower rod 41, and the two annular shells 51 are respectively located at the front and rear of the right side of the inside of the outer shell 2, and the outer sides of the two annular shells 51 are fixedly connected to a plurality of stabilizing rods 52 in an annular array, and each front stabilizing rod 52 is commonly fixedly connected to the opposite surface of its corresponding rear stabilizing rod 52 with a cross bar 53, and the rear end of the annular shell 51 located at the rear side of the inside of the outer shell 2 is fixedly connected to a slow rod 1 54, and the slow rod 1 54 is rotatably connected to the follower rod 41, and the lower part of the rear end of the outer shell 2 is rotatably connected to a slow rod 2 56, and the slow rod 2 56 is located directly below the slow rod 1 54, the slow rod 2 56 and the follower rod 41 are commonly wound with a belt 1 55 through a pulley, and the slow rod 1 54 and the slow rod 2 56 are commonly wound with a belt 2 57 through a pulley;

[0037] When the follower rod 41 rotates at a high speed, since the diameter of the slow rod 1 54 is larger than that of the follower rod 41, the belt 1 55 causes the slow rod 2 56 to rotate at a speed lower than that of the follower rod 41. Furthermore, the belt 2 57 causes the slow rod 1 54 and the slow rod 2 56 to rotate synchronously, so the rotation speed of the slow rod 1 54 is lower than that of the follower rod 41. After the yarn head is tied to one end of the cross bar 53, the drive motor 42 is turned on, which can eventually make the yarn slowly wrap around the entire cross bar 53. On the other hand, there is relative motion between the yarn and the internal cleaning device 4 during rotation, so that the brush 1 46 and the brush 2 75 can clean the surface of the yarn.

[0038] Specifically, in order to realize the function of the inner cleaning device 4 to clean the inner surface of the yarn, please refer to Figure 4 and Figure 7 In this solution, the internal cleaning device 4 includes a driving motor 42, which is located on the right side of the protective shell 8. The output end of the driving motor 42 is fixedly connected to a follower rod 41 through a linkage shaft. The follower rod 41 passes through the rear end of the shell 22 and extends to the inside of the shell 22. The front ring array of the follower rod 41 has four bases 43, and the four bases 43 are each provided with a cylindrical groove 1 inside. The top wall of the inner cavity of the cylindrical groove 1 is fixedly connected to a spring 44. One end of each spring 44 is fixedly connected to the top wall of the inner cavity of the groove 1, and the other end is fixedly connected to a support rod 45. The ends of the four support rods 45 away from the follower rod 41 are fixedly connected to a brush 46.

[0039] Under the action of spring 44, brush 46 together with support rod 45 can be extended and retracted toward the inner cavity of groove 1 to adapt to yarns of different diameters. Driving motor 42 causes follower rod 41 to rotate at high speed, so that brush 46 can rotate quickly to clean impurities. At the same time, follower rod 41 rotates at high speed to drive external cleaning device 7 and yarn winding assembly 5 to rotate.

[0040] Specifically, in order to realize the synchronous rotation and cleaning function of the external cleaning device 7, please refer to Figure 4 , Figure 6 , Figure 8 In this solution, the external cleaning device 7 includes a rotating rod 71, which passes through the left side of the rear end of the shell 2 and extends to the inside of the shell 2. A belt 76 is wound around the rotating rod 71 and the follower rod 41 through a pulley. Three bases 72 are fixedly connected to the front of the rotating rod 71 in an annular array. The three bases 72 are each provided with a cylindrical groove 2 inside. A spring 73 is fixedly connected to the top wall of the inner cavity of the cylindrical groove 2. One end of each spring 73 is fixedly connected to the top wall of the inner cavity of the groove 2, and the other end is fixedly connected to a support rod 74. The three support rods 74 are fixedly connected to a brush 75 at one end away from the rotating rod 71.

[0041] Under the action of belt 3 76, rotating rod 1 71 rotates synchronously with moving rod 41, thereby driving supporting rod 2 74 and brush 2 75 to rotate together, thereby realizing the function of cleaning the outer surface of the yarn; under the action of spring 2 73, brush 2 75 can be extended and retracted toward the inner cavity of groove 2, thereby cleaning yarns of different diameters;

[0042] The brush 1 46 and the brush 2 75 are densely arranged soft filaments, which can sweep away dust, grass clippings and other impurities on the inner and outer surfaces of the yarn without damaging the yarn.

[0043] Specifically, in order to achieve the effect that the yarn feeding assembly 6 makes the yarn feed in a reciprocating motion in the front-to-back direction, please refer to Figure 5 In this scheme, the yarn feeding assembly 6 includes a shell three 61, the shell three 61 is fixedly connected to the upper end of the shell two 2, the right end of the shell three 61 is slidably connected to the wire hole plate 62 through a slide groove, and a round hole is provided on the right side of the upper end of the wire hole plate 62. The rear side of the inner part of the shell three 61 is fixedly connected to the hydraulic cylinder base 63, and the output end of the hydraulic cylinder base 63 is fixedly connected to the hydraulic cylinder support rod 64, and a connecting rod 65 is fixedly connected between the rear end of the wire hole plate 62 and the end of the hydraulic cylinder support rod 64 away from the hydraulic cylinder base 63;

[0044] The hydraulic cylinder base 63 is opened continuously in the forward and reverse directions, and under the action of the hydraulic cylinder support rod 64, the wire hole plate 62 moves back and forth along the slide groove;

[0045] When feeding the yarn, the thread end can be passed through the round hole on the thread hole plate 62, and then bolted to one end of the cross bar 53 of the yarn winding assembly 5, so that the yarn can be spread on the cross bar 53 in a reciprocating motion, thereby preventing the yarn from being wound on the cross bar 53 in multiple layers and the inner surface of the superimposed outer layer of yarn cannot be cleaned;

[0046] Specifically, in order to realize the function of the discharge winding device 9 to extract the cleaned yarn from the yarn winding assembly 5, please refer to Figure 5 In this scheme, the discharging winding device 9 includes a shell 91, which is fixedly connected to the upper end of the shell 2, and the shell 91 is located at the rear side of the circular yarn outlet at the upper end of the shell 2. A motor 92 is fixedly connected inside the shell 91, and the output end of the motor 92 extends to the outside through the front end of the shell 91, and the output end of the motor 92 is fixedly connected to a winding rod 93 through a linkage shaft.
