Description

Technical Field

[0001] The present application relates to the technical field of cotton yarn production, and in particular to a loose fiber cleaning device for cotton yarn production. Background Art

[0002] Loose fibers (also known as "floating hair" or "floating flocs") in cotton yarn production refer to fiber bundles that accidentally fall off or extend from the yarn surface or product due to fiber breakage, improper combing and winding, etc. during the production process. They are usually between 1-30 mm in length. Loose fibers not only reduce product quality and cause defects and flaws, but may also cause equipment blockage and production interruption in the next process, affecting production efficiency and cost control.

[0003] In the related art, an external driving device is generally used to drive the cutter to rotate at high speed and make a circular motion around the yarn, thereby cutting the loose fibers. Under the action of the air extraction device, the loose fibers enter the internal part of the external dust collection device and are collected. However, the external driving device and the cutter are fixedly connected, and the cutter will continue to rotate after encountering abnormal resistance (for example, the yarn and the cutter are entangled), which can easily cause the cutter to break or the wire to break. In addition, the cleaned loose fibers cannot be reused, which causes a waste of resources to a certain extent. Summary of the invention

DETAILED DESCRIPTION

[0028] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0029] The following describes the loose fiber cleaning equipment for cotton yarn production according to an embodiment of the present application with reference to the accompanying drawings.

[0030] like Figure 1-Figure 9As shown, the loose fiber cleaning device for cotton yarn production of the embodiment of the present application may include: a fiber removal mechanism 1, a first capture mechanism 2, an air pump 3 and a second capture mechanism 4, wherein:

[0031] The fiber removal mechanism 1 includes a fixing plate 11 , a pipe 12 and a plurality of fiber removal components 13 .

[0032] The pipe fitting 12 is arranged on the fixing plate 11 .

[0033] It should be noted that the fixing plate 11 described in this embodiment is provided with a plurality of mounting holes, and relevant technicians can use fixing parts to fix the fiber removal mechanism 1 at a preset position of an external mechanical device (for example, on a weft winding machine) so that the yarn can pass through a plurality of fiber removal components 13.

[0034] The plurality of fiber removal components 13 are respectively connected to one end of the pipe 12 , and the fiber removal components 13 include an outer pipe 131 , an inner pipe 132 , a plurality of guide blades 135 and a cutting knife 136 .

[0035] The outer tube 131 is communicated with the pipe fitting 12 , the inner tube 132 is arranged inside the outer tube 131 , and rotating parts 133 are respectively provided at both ends of the inner tube 132 , and the rotating parts 133 are rotatably connected to the outer tube 131 .

[0036] It should be noted that the rotating portion 133 and the outer tube 131 described in this embodiment are rotatably connected via a bearing.

[0037] The inner wall of the inner tube 132 is provided with a plurality of through slots 134 , a plurality of guide blades 135 are equidistantly arranged on the outer wall of the inner tube 132 and located between the outer tube 131 and the inner tube 132 , and a cutting knife 136 is arranged on the inner wall of the inner tube 132 .

[0038] It should be noted that the multiple through grooves 134 are close to one end of the inner tube 132, the position where the pipe fitting 12 is connected to the outer tube 131 is close to the other end of the inner tube 132, and the multiple guide blades 135 are located between the through grooves 134 and the position where the pipe fitting 12 is connected to the outer tube 131.

[0039] It can be understood that the position where the tube 12 is connected to the outer tube 131, the multiple guide blades 135 and the through grooves 134 are arranged in sequence along the direction of yarn movement, which can ensure that air flows through the guide blades 135, so that the guide blades 135 drive the inner tube 132 to rotate under the action of the airflow.

[0040] The first capturing mechanism 2 includes a first shell 21 , a capturing component 22 and a spinning component 23 .

[0041] The first shell 21 is connected to the other end of the pipe 12 , the capture component 22 is arranged inside the first shell 21 , and the spinning component 23 is installed on the capture component 22 .

[0042] The air pump 3 is disposed between the first catching mechanism 2 and the second catching mechanism 4 .

[0043] Specifically, the fiber removal mechanism 1 is installed on an external textile device (eg, a weft winding machine, a drawing frame), so that the yarn passes through the fiber removal component 13, and the device is used to clean the loose fibers on the surface of the yarn.

[0044] When the device is started, the air pump 3 draws air, a negative pressure is formed inside the first capturing mechanism 2, and the external air enters between the inner tube 132 and the outer tube 131 through the through slot 134. The air impacts the guide blades 135. Under the action of the airflow, the guide blades 135 drive the inner tube 132 to rotate under the support of the outer tube 131, and the inner tube 132 drives the cutter 136 to rotate around the yarn. The loose fibers on the yarn act on the cutter 136, and the loose fibers are cut off by the cutter 136. The loose fibers follow the air through the through slot 134 and enter between the inner tube 132 and the outer tube 131, and then enter the inside of the first capturing mechanism 2 through the pipe fitting 12.

[0045] Since the cutting knife 136 is powered by air flow, when the cutting knife 136 encounters abnormal resistance (for example, entanglement with the yarn), the cutting knife 136 can stop in time, thereby avoiding the situation of knife collapse or yarn breakage.

[0046] The cut loose fibers and air enter the interior of the first shell 21 together. Under the blocking effect of the capture component 22, the fibers adhere to the capture component 22. The spinning component 23 can clean the surface of the capture component 22 and gather the fibers on the capture component 22 together. The fibers gather into a ball and fall to the bottom of the first shell 21, which is convenient for subsequent secondary utilization, thereby improving resource utilization.

[0047] Under the action of the air pump 3 , a portion of the fine particles passing through the first capturing mechanism 2 enters the interior of the second capturing mechanism 4 , and the fine particles are purified in the second capturing mechanism 4 .

[0048] In one embodiment of the present application, Figure 6 , Figure 7 and Figure 8 As shown, the capture assembly 22 includes a fixing frame 221 , a support plate 222 , a support base 223 and a filter screen 224 .

[0049] Among them, the fixed frame 221 is connected to the inner wall of the first shell 21, the support plate 222 is connected to the inner wall of the fixed frame 221 in a cross-shaped structure, the support base 223 is located in the middle of the fixed frame 221, the support base 223 is connected to the support plate 222, and the filter screen 224 is arranged inside the fixed frame 221, and the filter screen 224 is connected to the support plate 222 and the support base 223.

[0050] In one embodiment of the present application, Figure 6 As shown, the spinning and rubbing assembly 23 includes a driving motor 231 , a rod body 232 , a connecting member 233 , a connecting rod 234 and a spinning and rubbing member 235 .

[0051] Among them, the driving motor 231 is installed on the supporting base 223, one end of the rod body 232 is connected to the output shaft of the driving motor 231, the rod body 232 passes through the supporting base 223, the rod body 232 is rotatably connected to the supporting base 223, the connecting member 233 is connected to the other end of the rod body 232, the connecting rod 234 is connected to the connecting member 233, the rotating and rubbing member 235 is fixedly connected to the connecting rod 234, and the rotating and rubbing member 235 is in contact with the filter 224.

[0052] It should be noted that the material of the rubbing member 235 close to the filter screen 224 described in this embodiment can be made of silicone. The silicone has a certain degree of softness and can carry the clumped fibers to move during the process of gathering the fibers.

[0053] In one embodiment of the present application, Fig. 9 As shown, a first inclined portion 2351 and a protruding portion 2352 are provided at the bottom of the spinning and rubbing member 235 .

[0054] It can be understood that the first inclined portion 2351 and the raised portion 2352 provided at the bottom of the rotary rubbing member 235 can reduce the friction and fall of the fibers attached to the filter screen 224 by the rotary rubbing member 235, so that the fibers are placed between the rotary rubbing member 235 and the filter screen 224, and the fibers are gathered into a ball between the two.

[0055] Specifically, the loose fibers cut by the air are blocked by the filter 224, and the loose fibers adhere to the surface of the filter 224. The driving motor 231 drives the rod body 232 to rotate at a constant speed. Under the transmission action of the connecting piece 233 and the connecting rod 234, the rotating piece 235 moves on the surface of the filter 224 to generate static friction between the filter 224, and the fibers are gathered into balls between the rotating piece 235 and the filter 224. The rotating piece 235 continues to move, and the volume of the fiber balls increases. When the volume of the balls is slightly larger, the fiber balls will be squeezed out by the rotating piece 235. The extruded fiber balls fall to the bottom of the first shell 21, and the fiber balls will not continue to move with the air, so that it is convenient for relevant technical personnel to uniformly handle the fiber balls in the later stage, thereby improving the utilization rate of resources.

[0056] In one embodiment of the present application, Figure 6 As shown, a collecting box 24 is disposed at the bottom of the first shell 21 , and a second inclined portion 240 is disposed on the fixing frame 221 . The second inclined portion 240 is located obliquely above the collecting box 24 .

[0057] It can be understood that setting the second inclined portion 240 can prevent fiber clumps from accumulating on the fixed frame 221, and setting the collecting box 24 can temporarily store the fiber clumps, and the bottom of the collecting box 24 sinks to below the first shell 21, thereby reducing the impact of the flow of air inside the first shell 21 on the fiber clumps.

[0058] In one embodiment of the present application, Figure 1 As shown, the second capturing mechanism 4 includes a second shell 41 , a circulating filtering device 42 , a spray component 43 and a ventilation pipe 44 .

[0059] The circulation filter device 42 is disposed on the second shell 41 , the spray component 43 is installed between the second shell 41 and the circulation filter device 42 , and the ventilation pipe 44 is disposed on the second shell 41 .

[0060] It should be noted that the specific structure of the circulating filtering device 42 described in this embodiment has been disclosed in the prior art, so it will not be described in detail here.

[0061] Under the action of the air pump 3, some fine particles enter the interior of the second shell 41, and the spray component 43 sprays the interior of the second shell 41 to reduce dust. Then, the particles enter the interior of the circulation filter device 42 to be purified, and the treated water is continuously recycled, thereby achieving the purpose of saving water resources.

[0062] After a period of time, relevant technicians can inspect and repair the circulating filtering device 42 to ensure the normal operation of the second capturing mechanism 4.

[0063] In one embodiment of the present application, Figure 7 and Fig. 9 The inner wall of the fixing frame 221 is provided with a first guide groove 251 , the inner wall of the supporting base 223 is provided with a second guide groove 252 , and the outer wall of the rotating and rubbing member 235 is symmetrically provided with two guide wheels 253 , which are respectively rollingly connected and arranged in the first guide groove 251 and the second guide groove 252 .

[0064] It can be understood that the first guide groove 251 and the second guide groove 252 use the guide wheel 253 to limit the rotating and rubbing member 235, so as to ensure that the rotating and rubbing member 235 contacts the filter screen 224, thereby forming a gathering effect.

[0065] In one embodiment of the present application, Figure 1 As shown, the cutting knives 136 are arranged in a spiral structure.

[0066] It is understandable that the spiral structure of the cutting knife 136 is less likely to disturb the air inside the inner tube 132 than a straight cutting knife, thereby preventing the loose fibers from swaying with the air and ensuring that the loose fibers and the cutting knife 136 can interact directly.

[0067] The instantaneous contact amount between the cutting knives 136 arranged in a spiral structure and the loose fibers is smaller, so that the loose fibers are easier to clean.

[0068] In summary, the loose fiber cleaning equipment for cotton yarn production in the embodiment of the present application utilizes air to impact the guide blades after passing through the through groove, thereby driving the inner tube and the cutting knife to rotate at high speed to clean the loose fibers. Under the premise of ensuring that the cutting knife can rotate at high speed, when the cutting knife encounters abnormal resistance, the cutting knife can stop in time to avoid the occurrence of knife breakage or wire breakage; in addition, inside the first capture mechanism, the spinning and rubbing component can gather the loose fibers blocked on the capture component into balls, and the balled loose fibers gather at the bottom of the first capture mechanism, which is convenient for subsequent secondary utilization, thereby improving resource utilization.
