Description

Technical Field

[0001] The present invention relates to the technical field of spinning, and specifically to a spinning device and method capable of cleaning fluff. Background Art

[0002] In textile processing, operations such as opening, carding, drawing, drafting, and twisting are required. Fiber raw materials (such as cotton and chemical fibers) are loosened into small pieces to remove impurities. The fibers are further loosened, straightened, and arranged in parallel through a carding machine to form a sliver. Multiple slivers are combined and drafted to improve uniformity and form a finer roving. The roving is further drafted and twisted to form a coarse yarn. The coarse yarn is finally drafted and twisted through a ring spinning frame to form a fine yarn. During drafting or twisting, fluff (short fibers falling off or breaking) is generated due to high-speed rotation and friction of the yarn. Excessive fluff affects the smoothness, strength, and dyeing uniformity of the fabric. The fluff accumulates on the twisting components, which aggravates mechanical wear. The flying fluff pollutes the workshop air and endangers the health of workers.

[0003] In a spinning device for producing environmentally friendly colored yarns disclosed in the existing patent with the publication number CN211100520U, it includes a spinning machine body, a dust collection hood, a dust suction pipe, and a fan. Columns are fixed on both sides of the top of the spinning machine body, and a cover plate is fixed between the tops of the columns. A drive box is fixed at the center of the bottom of the cover plate. Two turntables are arranged in the inner cavity of the drive box. Protrusions are arranged on the front surfaces of both turntables. The protrusions are arranged at the edges of the front surfaces of the turntables, and the protrusions and the turntables are integrally formed structures. Through the settings of the fan, the dust suction pipe, and the dust collection hood, the debris and fluff generated during the spinning process can be absorbed. The above dust suction components are fixed at a certain position and affect the processing of the yarn. Or in an energy-saving intelligent dust removal device for textile processing disclosed in the existing patent with the publication number CN118904857B, it includes a moving base, a dust removal cylinder, a first filter plate installed at one end inside the dust removal cylinder, a second filter plate installed at the other end inside the dust removal cylinder, a fixed cylinder for knocking and vibrating the first filter plate, and a conveying cylinder for spraying the second filter plate. Square base cylinders are fixedly installed at the centers of both ends of the top of the moving base through bolts. The dust removal cylinder is fixedly installed between the tops of the base cylinders through bolts. An arc-shaped rear cover with a suction fan is fixedly installed on the outer periphery of the dust removal cylinder at one end where the second filter plate is located. The device can be moved to perform dust suction treatment on different areas. The above device is an external design and needs to be additionally installed outside the equipment, occupying workshop space. Moreover, its coordination with the spinning equipment is poor, and the independent system is difficult to dynamically match the spinning process, and the cleaning efficiency is out of sync with the production rhythm. To address the above problems, a spinning device and method capable of cleaning fluff are proposed. Summary of the Invention

[0040] like Figure 4 and Figure 5 As shown, a pay-off mechanism 2 is arranged on the top of the device body 11 and is used for pay-off of the yarn roll; the pay-off mechanism 2 comprises a central tube 21 and a protective cover 22 installed on the top of one side of the device body 11, the yarn tube is placed between the central tube 21 and the protective cover 22, a central column 27 is rotatably installed in the central tube 21, the central column 27 is rotatably matched with the device body 11, and a pay-off motor for driving the central column 27 to rotate is installed in the device body 11; the top of the central column 27 is fixedly connected to a rotating head 23, a plurality of balls that can roll in an annular groove at the top of the central tube 21 are installed at the bottom of the rotating head 23, the ball design reduces the rotation resistance and avoids yarn breakage or wear, a groove is provided in the middle of the rotating head 23, and a pulling rod 24 is rotatably connected in the groove, the end of the pulling rod 24 is connected to a pulling ring 25 for yarn to pass through, one end of the pulling rod 24 close to the rotation connection with the rotating head 23 is threadedly connected to a fixing bolt 26, and a screw hole threadedly matched with the fixing bolt 26 is provided at the bottom of the groove;

[0041] Specifically, the yarn roll is placed between the central tube 21 and the protective cover 22, the central column 27 is driven by the pay-off motor to rotate and release the yarn, the rotating head 23 rotates with low friction in the annular groove at the top of the central tube 21 through the ball bearing, the pulling ring 25 guides the yarn path, and the pulling rod 24 is adjustable in horizontal and vertical positions. When adjusting the vertical position, it is convenient to put in the yarn tube. When adjusting the horizontal position, the fixing bolt 26 can be tightened to connect the fixing bolt 26 with the screw hole in the groove.

[0042] like Figure 3As shown in the figure, the drafting mechanism 3 is installed on one side of the device main body 11 and is used for drafting the yarn. The drafting mechanism 3 includes a fixing frame 31 installed on one side of the device main body 11. A first drafting wheel 32 and a second drafting wheel 33 are installed on the fixing frame 31. The first drafting wheel 32 is placed on the side close to the device main body 11 at the bottom of the second drafting wheel 33, and the outer diameter of the first drafting wheel 32 is smaller than that of the second drafting wheel 33.

[0043] Specifically, the yarn passes through the drafting area between the first drafting wheel 32 and the second drafting wheel 33 to achieve uniform extension of the yarn.

[0044] As Figure 3 shown in the figure, the winding mechanism 4 is installed on the side of the top of the device main body 11 away from the drafting mechanism 3 and is used for winding the yarn after drafting. The winding mechanism 4 includes a winding roller 41 installed on the top of the device main body 11 and a floating pressing frame 42. A long rod 43 is provided on the side of the winding roller 41 close to the drafting mechanism 3. A wire guiding frame 44 corresponding to the winding roller 41 and through which the yarn passes is installed on the long rod 43. A supporting sliding seat for horizontally sliding the long rod 43 is provided on the device main body 11. A corresponding motor can be set to drive the winding roller 41, and the floating pressing frame 42 can select an existing structure to adaptively adjust the winding tension.

[0045] Specifically, the long rod 43 slides horizontally back and forth. The wire guiding frame 44 guides the yarn to be evenly arranged on the surface of the winding roller 41. The reciprocating wire guiding frame 44 avoids yarn accumulation and improves the winding quality.

[0046] As Figure 2 shown in the figure, the air inlet cleaning mechanism 5 is installed between the yarn unwinding mechanism 2 and the drafting mechanism 3. It includes a guiding cylinder 51 for the yarn to pass through, air guide pipes 52 installed on both sides of the guiding cylinder 51 and in the radial direction, an air outlet pipe 54 installed at the end of one group of air guide pipes 52, and a Venturi tube 55 connected to the air outlet end of the air outlet pipe 54 through a trachea and extending into the device main body 11. A dust suction hopper 56 is provided on the top of the device main body 11. The dust suction hopper 56 is connected to the throat of the Venturi tube 55 through a connecting pipe group.

[0047] Specifically, compressed air blows the surface of the yarn radially from the air guide pipes 52 to strip loose fluff. The dust-containing air flow enters the Venturi tube 55 through the air outlet pipe 54. A high-speed air flow at the throat generates a negative pressure, and the escaping fluff around the dust suction hopper 56 is sucked in through the connecting pipe group. The air flow scouring directly removes the hairiness on the surface of the yarn, reduces the pollution in subsequent processes, and the Venturi effect cooperates with the dust suction hopper 56 to form a local negative pressure area, reducing the diffusion of fluff to the workshop environment.

[0048] As Figure 6 and Figure 7As shown, a buffer mechanism 8 is used to collect the dust-containing gas output by the Venturi tube 55, and one set of buffer mechanism 8 is arranged on one side of every three sets of device main bodies 11; and a filtering mechanism 9 is arranged at the bottom of the buffer mechanism 8 for filtering the dust-containing gas. The buffer mechanism 8 includes a storage tank 81, an input pipe 82 connected to the top of the storage tank 81, and an installation pipe 83 connected to one end of the input pipe 82 away from the storage tank 81. The installation pipe 83 is connected to the air outlet end of the Venturi tube 55, and the air outlet end of the storage tank 81 is connected to an output pipe 84. Electric valves are connected to both the input pipe 82 and the output pipe 84, and a pressure detector is installed on the storage tank 81 for detecting the internal pressure of the storage tank 81.

[0049] Specifically, the dust-containing gas is temporarily stored in the storage tank 81, and the pressure detector monitors the pressure inside the tank. When the pressure reaches the threshold value, the electric valve opens, and the gas enters the filter tank 91. The electric valves of the input pipe 82 and the output pipe 84 control the gas flow in stages, avoiding sudden changes in the system pressure, releasing the gas flow in stages, and protecting the filtering mechanism 9 from impact.

[0050] As Figure 3 As shown, the reciprocating mechanism 6 includes a moving frame 61 installed at one end of a long rod 43. An air-operated telescopic rod for adjusting the horizontal reciprocating motion of the moving frame 61 is installed in the device main body 11. A vertical rod 62 is connected to the bottom of the moving frame 61, and one end of the bottom of the vertical rod 62 is connected to a cross rod 63 that is slidably matched with the device main body 11. The cross rod 63 slidably passes through three sets of device main bodies 11. One set of the Venturi tubes 55 passes through three sets of the device main bodies 11. The connection pipe group includes a centralized pipe 58, and the centralized pipe 58 is communicated with three dust suction hoppers 56. The bottom of the centralized pipe 58 is connected to a connection pipe 57 that is connected to the throat of the Venturi tube 55.

[0051] Specifically, the air-operated telescopic rod pushes the moving frame 61 to reciprocate horizontally, drives the long rod 43 and the wire guide frame 44 to evenly arrange the yarn. The reciprocating motion ensures that the yarn is wound tightly and evenly. The cross rod 63 drives three sets of device main bodies 11 to realize the multi-station synchronous wire winding action and improve the overall efficiency.

[0052] As Figure 8As shown, the filtering mechanism 9 includes a filter tank 91 arranged at the bottom of the storage box 81 and connected to the output pipe 84, the top of the filter tank 91 away from one end of the output pipe 84 is connected to the exhaust pipe 92, the exhaust pipe 92 extends to one side of the output pipe 84, the bottom of the filter tank 91 is connected to the storage box 93, at least two groups of filter discs 97 are installed in the filter tank 91, the filter tank 91 is rotatably connected to the drive rod 95, the filter disc 97 is provided with a rotating hole that is rotatably matched with the drive rod 95, and the drive rod 95 is fixedly connected with a cleaning rod 98 placed on the air inlet side of the filter disc 97; an atomizing nozzle 99 is installed at the top of the inner cavity of the filter tank 91; during dust removal and filtering, the atomizing nozzle 99 can also be connected to an external pipeline, and gas filtration is combined with atomization dust reduction to improve the dust and fluff capture effect;

[0053] Specifically, when the dust-containing gas passes through the filter disc 97, the fluff is trapped and the clean gas is discharged through the exhaust pipe 92. The driving rod 95 drives the cleaning rod 98 to rotate, scraping off the fluff accumulated on the surface of the filter disc 97, and the fallen fluff falls into the bottom storage box 93. The cleaning rod 98 automatically clears the blockage of the filter disc 97, reducing the frequency of manual maintenance.

[0054] like Figure 6 and Figure 7 As shown, the toggle mechanism 7 is arranged on one side of the buffer mechanism 8, and is used to drive the driving rod 95 to rotate. The toggle mechanism 7 includes a driving disk 71, and a support frame for supporting the driving disk 71 to stably rotate is installed on one side of one group of the device body 11. The driving disk 71 is eccentrically connected to the connecting rod 72 at one side away from the supporting frame. The connecting rod 72 is rotatably connected to a sliding rod 73 that slidably cooperates with the device body 11 at one end away from the driving disk 71. The sliding rod 73 is connected to the end of the connecting rod 72 away from the vertical rod 62 of the cross bar 63. The driving wheel 74 is fixedly connected to the shaft end of the driving disk 71 close to the supporting frame. A power shaft 94 is provided on one side of the filter tank 91. A driven wheel 75 is installed on the power shaft 94. The driving wheel 74 and the driven wheel 75 are connected by a synchronous belt transmission. One end of the driving rod 95 extends to the outside of the filter tank 91 and is connected to the power shaft 94 through a pneumatic friction clutch 96.

[0055] Specifically, the movement of the cross bar 63 drives the drive plate 71 to rotate through the sliding rod 73 and the connecting rod 72, and is transmitted to the power shaft 94 through the synchronous belt. The pneumatic friction clutch 96 engages when the gas pressure reaches the standard, and transmits power to the drive rod 95 to drive the filter plate 97 for cleaning. The inertia of the equipment movement drives the filter plate 97 for cleaning without additional energy consumption. The pneumatic friction clutch 96 automatically controls the cleaning cycle according to the pressure in the filter tank 91 to avoid excessive wear.

[0056] The working principle of the present invention is as follows: the yarn roll to be drafted is placed between the central tube 21 and the protective cover 22 of the pay-off mechanism 2 to ensure that the yarn tube is fixed, and the yarn head is passed through the pulling ring 25, the guide tube 51, the first drafting wheel 32 and the second drafting wheel 33 in turn, and finally fixed to the take-up roller 41, and the pay-off motor is started to drive the central column 27 to rotate, drive the rotating head 23 to rotate, and the pulling ring 25 pays off the yarn at a uniform speed. When the yarn passes through the guide tube 51, compressed air is introduced into the air guide pipe 52, and the airflow radially sweeps the yarn surface from both sides of the guide tube 51 to peel off the loose fluff. The yarn enters the drafting mechanism 3 for drafting, and the fluff stripped from the guide tube 51 enters the Venturi tube 55 along with the air flow through the outlet pipe 54. The high-speed air flow forms a negative pressure at the throat, and the scattered fluff of the three groups of dust hoppers 56 is sucked into the system through the connecting pipe 57 and the central pipe 58. The dust-containing gas is transported to the buffer mechanism 8 along the Venturi tube 55. The storage box 81 temporarily stores the gas. The pressure detector monitors the pressure in real time. When the pressure reaches the threshold, the electric valve of the output pipe 84 is opened, and the gas enters the filter tank 91. When the gas passes through the filter disc 97, the fluff is intercepted, and the clean gas is discharged through the exhaust pipe 92.

[0057] When the outlet pressure of the exhaust pipe 92 on the filter tank 91 is lower than the inlet pressure of the output pipe 84, the electric valve on the output pipe 84 can be closed, the pneumatic friction clutch 96 allows gas to pass, the driving rod 95 and the power shaft 94 are transmitted, the driving rod 95 drives the cleaning rod 98 to rotate, scrapes off the fluff accumulated on the surface of the filter plate 97, and the fallen fluff falls into the bottom storage box 93.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
