Description

Technical Field

[0001] This application relates to the field of cotton fiber preparation technology, and in particular to a device for removing impurities from cotton fibers. Background Technology

[0002] Cotton tufts, as small fiber clusters or bundles formed by many individual fibers adhering and entangled together in the early stages of spinning, can be broken down into independent individual fibers during the carding process. Therefore, they play a crucial role as an important raw material in the carding process. During the production of cotton tufts, after the cotton bales are opened by the cotton grabber, the cotton tufts are often transported by airflow through conveyor pipes to a blender for mixing, thereby improving the uniformity of the cotton fibers.

[0003] Regarding the aforementioned technologies, due to the presence of certain impurities within the cotton fibers, static charges are generated during the transportation of the cotton fibers within the conveying pipeline, resulting in friction between the cotton fibers and between the cotton fibers and impurities. This static charge can easily cause the cotton fibers to approach and entangle with each other, forming large fiber clusters. Consequently, these fiber clusters can easily clog the pipeline and subsequent equipment, reducing the quality of subsequent products. Therefore, improvements are needed. Summary of the Invention

[0004] In order to reduce the probability of cotton fibers forming large fiber clusters under the action of static electricity, this application provides a device for removing impurities from cotton fibers.

[0005] The present application provides a device for removing impurities from cotton fibers, which adopts the following technical solution: A device for removing impurities from cotton fibers includes an impurity removal mechanism, which comprises a separation chamber and a separation component. The separation chamber has a separation cavity, and both ends of the separation cavity are connected to a conveying pipe for conveying cotton fibers. The separation component is used to separate impurities from the cotton fibers in the separation cavity. The middle part of the separation cavity is bent downwards, and a storage box is provided below the downward bend of the separation cavity to collect the separated impurities. An electrostatic eliminator is also provided in the separation cavity to eliminate static charge on the cotton fibers.

[0006] By adopting the above technical solution, compared with the prior art, where friction generates static charge between cotton fibers and between cotton fibers and impurities, the cotton fibers are prone to approaching and entanglement under static electricity, forming large fiber clusters. The present application's impurity removal mechanism and static elimination rod enable the static elimination rod to eliminate the static charge on the cotton fibers in the separation chamber, and the impurity removal component to separate impurities in the cotton fibers in the separation chamber. At the same time, the presence of the collection box can collect the separated impurities. These settings effectively reduce impurities in the cotton fibers, thereby effectively reducing the static charge generated by the cotton fibers, effectively reducing the probability of the cotton fibers forming large fiber clusters under static electricity, thus reducing the probability of the formed fiber clusters clogging the pipes and subsequent settings, and ensuring the quality of subsequent products.

[0007] Preferably, the separation component includes a spiral blade and several flow-blocking bars. The spiral blade is disposed in the separation cavity and is spirally arranged along the extension direction of the separation cavity. The static elimination bar passes through the spiral blade. Several flow-blocking bars are disposed between the downward bend of the separation cavity and the storage box to collide with the separated impurities, so that the impurities fall into the storage box after the collision.

[0008] By adopting the above technical solution and setting the separation component, the cotton fibers can move spirally along the side wall of the spiral blade when they enter the separation chamber. As the cotton fibers move spirally, impurities can be separated from the cotton fibers under the action of centrifugal force. The separated particulate impurities fall into the collection box below the flow barrier after colliding with the flow barrier bar, thereby achieving the separation of impurities in the cotton fibers.

[0009] Preferably, the conveying pipeline is also equipped with an alarm mechanism, which includes a detection component, a control component, and an alarm. The detection component is used to detect whether there are static sparks, impurities, or stains in the separated cotton fiber bundles. The control component is used to control whether the alarm emits an audible and visual alarm based on the data detected by the detection component.

[0010] By adopting the above technical solution and setting the alarm mechanism, the detection component can detect whether there are static sparks, impurities or stains in the cotton fiber bundle. Thus, the control component can, based on the data detected by the detection component, control the alarm to issue an audible and visual alarm when the detection component detects the presence of static sparks, impurities or stains, thereby making it easier for staff to be informed and reducing the probability of safety hazards.

[0011] Preferably, the conveying pipeline is also equipped with a buffer chamber and a three-way gate valve. The control component is used to control the opening of the three-way gate valve when the detection component detects the presence of electrostatic sparks, impurities or stains, so as to allow abnormal cotton fibers to enter the buffer chamber.

[0012] By adopting the above technical solution, the buffer chamber and the three-way gate valve are configured so that when the detection component detects static sparks, impurities or stains in the separated cotton fiber bundles, the control component can control the opening of the three-way gate valve to open the channel between the conveying pipeline and the buffer chamber, so that the abnormal cotton fiber bundles enter the buffer chamber, thereby reducing the probability of the cotton fiber bundles adversely affecting subsequent processes.

[0013] Preferably, the bottom of the separation compartment is provided with an opening, the storage box is located inside the opening of the separation compartment and is used to close the opening of the separation compartment. One end of the storage box is rotatably connected to the separation compartment, and the other end is provided with an opening. The storage box is also provided with a closing mechanism, which is used to close the opening on the storage box.

[0014] By adopting the above technical solution, the storage box and the sealing mechanism are designed so that when the storage box rotates, the sealing mechanism can gradually open the opening on the storage box, so that the impurities stored in the storage box cavity can be discharged through the opening of the storage box, thereby realizing the emptying of the impurities in the storage box.

[0015] Preferably, the storage box is also provided with a push-out mechanism, which includes a push-out frame and a linkage component. The push-out frame is slidably connected to the storage box, and the straight line of the sliding direction passes through the opening of the storage box. The bottom of the push-out frame abuts against the inner bottom wall of the storage box, and the linkage component is used to drive the push-out frame to slide.

[0016] By adopting the above technical solution and configuring the ejection mechanism, when the storage box rotates, the linkage component can drive the ejection frame to slide, thereby gradually approaching the opening of the storage box. This gradually pushes the impurities inside the storage box toward the opening, effectively reducing the number of impurities remaining on the bottom wall of the storage box. This reduces the probability that the remaining impurities will continue to remain in the cotton fibers with the airflow in the separation chamber, and also effectively accelerates the speed at which impurities pass through.

[0017] Preferably, the linkage assembly includes a rotating frame, a driving frame, and a linkage component. The rotating frame is rotatably connected to the separation chamber. One end of the driving frame is slidably connected to the rotating frame, and the other end is rotatably connected to the ejection frame. The storage box is used to drive the rotating frame to rotate through the linkage component.

[0018] By adopting the above technical solution and setting the linkage components, when the storage box rotates, the storage box can drive the rotating frame to rotate through the linkage components. In turn, the rotating frame drives the drive frame to rotate together during the rotation process, and the drive frame slides relative to the rotating frame. This causes the drive frame to drive the ejector frame to slide, thereby driving the ejector frame. At the same time, the presence of the rotating frame and the drive frame can effectively extend the driving range of the ejector frame's sliding, so that the ejector frame can be as close as possible to the opening on the storage box, thus ensuring the ejection effect of impurities.

[0019] Preferably, the closing mechanism includes a closing frame and a transmission component. The top of the closing frame is rotatably connected to the storage box and is used to close the opening on the storage box. The rotating frame is used to drive the closing frame to rotate through the transmission component.

[0020] By adopting the above technical solution and setting the closure mechanism, the storage box can drive the closure frame to rotate through the transmission component during the rotation of the storage box, thereby driving the closure frame. This allows the closure frame to rotate automatically when the storage box rotates, thus automatically opening the opening and effectively facilitating the operation of the staff.

[0021] Preferably, the transmission component includes a transmission frame, one end of which is rotatably connected to the rotating frame, and the rotatable connection point is different from the rotatable connection point of the rotating frame itself; the other end of the transmission frame is rotatably connected to the enclosing frame, and the rotatable connection point is different from the rotatable connection point of the enclosing frame itself.

[0022] By adopting the above technical solution and configuring the transmission frame, when the rotating frame rotates, the rotating frame can drive the transmission frame to move, thereby causing the end of the transmission frame away from the rotating frame to drive the closing frame to rotate, thus realizing the drive for the rotation of the closing frame. This effectively realizes the linkage between the closing frame and the ejection frame, facilitating the operation of the staff.

[0023] Preferably, the linkage includes a linkage frame, one end of which is rotatably connected to the storage box, and the rotatable connection point is different from the rotatable connection point of the storage box itself; the other end of the linkage frame is rotatably connected to the rotating frame, and the rotatable connection point is different from the rotatable connection point of the rotating frame itself.

[0024] By adopting the above technical solution and setting the linkage frame, when the storage box rotates, the storage box can drive the linkage frame to move, thereby causing the end of the linkage frame away from the storage box to drive the rotating frame to rotate, thus realizing the drive of the rotating frame to rotate. This effectively realizes the linkage between the storage box and the ejection frame, facilitating the operation of the staff.

[0025] In summary, this application includes at least one of the following beneficial technical effects: The inclusion of a cleaning mechanism and an antistatic bar allows the antistatic bar to eliminate static charges on the cotton fibers within the separation chamber, while the cleaning component separates impurities from the cotton fibers. The collection box collects the separated impurities. These features effectively reduce impurities in the cotton fibers, thereby reducing the static charge generated by the fibers and decreasing the likelihood of large fiber clusters forming under static electricity. This reduces the chance of these clusters clogging the pipes and subsequent components, ensuring the quality of the final product. The separation component is designed so that when the cotton fibers enter the separation chamber, they can move spirally along the side wall of the spiral blade. As the cotton fibers move spirally, impurities can be separated from the cotton fibers under the action of centrifugal force. The separated particulate impurities collide with the flow-blocking bar and fall into the collection box below the flow-blocking bar, thereby achieving the separation of impurities in the cotton fibers. The ejection mechanism is designed so that when the storage box rotates, the linkage component can drive the ejection frame to slide, gradually approaching the opening of the storage box. This pushes the impurities inside the storage box towards the opening, effectively reducing the number of impurities remaining on the bottom wall of the storage box. This reduces the likelihood of impurities remaining in the cotton fibers with the airflow in the separation chamber, and also effectively speeds up the passage of impurities.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] Example 1

[0033] Embodiment 1 of this application discloses a device for removing impurities from cotton fibers. (Refer to...) Figure 1 and Figure 2 The impurity removal device for cotton fibers includes an impurity removal mechanism 1, which comprises a separation chamber 11 and a separation component 12. The separation chamber 11 has a separation cavity 111, with both ends of the separation cavity 111 connected to a conveying pipe 2 for conveying cotton fibers. The separation component 12 separates impurities from the cotton fibers within the separation cavity 111. The middle of the separation cavity 111 is bent downwards, and a storage box 3 is located below the downward bend to collect the separated impurities. An electrostatic eliminator 4 is also provided within the separation cavity 111 to eliminate static charges on the cotton fibers.

[0034] Reference Figure 1 and Figure 2 One end of a conveying pipe 2 is connected to a device for conveying cotton fibers in an upward process, and the other end is fixedly connected to a separation chamber 11 and communicates with one end of a separation cavity 111. The middle of the separation cavity 111 is bent downward to form a "V" shape, thus forming two sections. The other end of the separation cavity 111 is connected to one end of another conveying pipe 2, and the other end of this conveying pipe 2 is used to connect to a device for the next process. In this embodiment, an airflow generating device is also provided at the end of one of the conveying pipes 2 to allow the cotton fibers to be conveyed under the action of airflow. This airflow generating device is prior art and will not be described in detail here.

[0035] Reference Figure 2The separation assembly 12 includes a spiral blade 121 and several flow-blocking bars 122. There are two spiral blades 121 and two static-eliminating bars 4, each located in one of the two sections of the separation cavity 111. The outer side of each spiral blade 121 is fixedly connected to the inner wall of the corresponding section of the separation cavity 111, so that the two sections of the separation cavity 111 form a spiral channel for the spiral movement of the cotton fiber bundle. Each static-eliminating bar 4 passes through the center of its corresponding spiral blade 121 and is fixedly connected to it, with the axis of each static-eliminating bar 4 being the same as the axis of its corresponding spiral blade 121.

[0036] Reference Figure 2 The axes of several flow-blocking bars 122 are arranged in parallel, and the axis of each flow-blocking bar 122 is perpendicular to the axis of the spiral blade 121. Each flow-blocking bar 122 is located on the lower side of two spiral blades 121, and both ends are fixedly connected to the inner wall of the separation chamber 11 to collide with impurities in the cotton fibers.

[0037] Reference Figure 2 One end of the storage box 3 extends into the separation chamber 11 and is slidably connected to the separation chamber 11 via a slide rail, with the sliding direction parallel to the axis of the flow-blocking rod 122. The other end of the storage box 3 extends out of the separation chamber 11 and is provided with a handle for easy retrieval. In this embodiment, a locking structure may also be provided inside the separation chamber 11 to lock the storage box 3. This locking structure is prior art and will not be described in detail here. The storage box 3 is located directly below several flow-blocking rods 122 and has an opening at the top to collect the separated impurities.

[0038] Reference Figure 1 An alarm mechanism 5 is also provided on one of the conveying pipes 2. The alarm mechanism 5 includes a detection element 51, a control element 52, and an alarm 53. In this embodiment, the control element 52 is a PLC controller, and the detection element 51 is an integrated detector. The integrated detector is fixedly installed on one of the conveying pipes 2 and has a cavity inside to communicate with the conveying pipe 2, allowing the cotton fibers to pass through the cavity. In other embodiments, the control element 52 can also be an industrial computer for convenient display.

[0039] Reference Figure 1 The chamber is equipped with a metal spark detector, an ultraviolet flame detector, and an industrial camera. These components, along with an alarm (53), are all electrically connected to a PLC controller or control computer. The metal spark detector is used to detect metal impurities in the cotton fibers and to detect tiny spark particles within them. The ultraviolet flame detector is used to detect the light emitted in the ultraviolet band from electrostatic discharge sparks, thus enabling the detection of electrostatic sparks.

[0040] Reference Figure 1Industrial cameras are used to visually inspect cotton fibers and, based on image recognition algorithms pre-stored in PLC controllers or industrial computers, separate the acquired images so that the algorithms in the PLC controllers or industrial computers can identify parts that are inconsistent with normal cotton fibers based on features such as color, grayscale, and texture.

[0041] Reference Figure 1 The alarm 53 is fixedly installed on the conveying pipe 2 where the integrated detector is located, and is situated between the dust collection detector and the separation chamber 11. The various detection devices within the integrated detector are used to feed back the detected data to the PLC controller. This allows the PLC controller to activate the alarm 53 to issue an audible and visual alarm when the integrated detector detects metallic impurities, electrostatic sparks, or stains within the cotton fiber bundle, indicating an abnormality in the detection data. This facilitates notification to staff.

[0042] Reference Figure 1 The conveying pipe 2 where the alarm 53 is located is also equipped with a buffer chamber 6 and a three-way gate valve 7. The three-way gate valve 7 is fixedly installed on the conveying pipe 2 and is located on the side of the detection element 51 away from the alarm 53. Both ends (the top two ends) of the three-way gate valve 7 are connected to the conveying pipe 2 so that the cotton fibers can pass through the three-way gate valve 7 from the upper section of the conveying pipe 2 to the lower section. The top of the buffer chamber 6 is fixedly connected to the bottom of the three-way gate valve 7, and the top of the buffer chamber 6 has a chamber. The other end (bottom end) of the three-way gate valve 7 is connected to the top of the buffer chamber 6, and the bottom of the buffer chamber 6 has an opening for the cotton fibers to pass through.

[0043] Reference Figure 1 In this embodiment, the bottom of the buffer compartment 6 is further provided with an arc-shaped cover plate, which is fitted onto the bottom of the buffer compartment 6 and closes the opening at the bottom of the buffer compartment 6. The arc-shaped cover plate is rotatably connected to the buffer compartment 6, and a pull rod is provided at the top, so that the operator can drive the arc-shaped cover plate to rotate through the pull rod to open the bottom of the buffer compartment 6.

[0044] Reference Figure 1 The three-way gate valve 7 is electrically connected to the PLC controller. When the integrated detector detects metal impurities, electrostatic sparks or stains in the cotton fiber bundle, i.e. when the detection data is abnormal, the PLC controller can control the three-way gate valve 7 to close the valve at the top end away from the detection element 51 and open the valve at the bottom, so that the abnormal cotton fiber bundle enters the buffer chamber 6.

[0045] The implementation principle of the impurity removal device for cotton fibers in Embodiment 1 of this application is as follows: During use, the cotton fibers enter the separation chamber 111 of the separation chamber 11 via the conveying pipe 2. After being guided by the spiral blade 121, the impurities inside the fibers are separated from the fibers. The separated impurities collide with the flow-blocking rod 122 and fall into the collection box 3. During this process, the static electricity eliminator 4 eliminates the static charge on the cotton fibers in the separation chamber 111, thereby reducing the probability of the cotton fibers forming large fiber clusters under the action of static electricity.

[0046] Example 2

[0047] The difference between Embodiment 2 and Embodiment 1 in this application is that: (Refer to...) Figure 3 and Figure 4 One end of the storage box 3 is rotatably connected to the separation chamber 11 along its length via a pin, and the other end has an opening so that impurities inside the storage box 3 can pass through the opening after it is rotated and tilted. The cross-sectional area of ​​the bottom of the storage box 3 is larger than the cross-sectional area of ​​the rest of the box to ensure a sealing effect on the bottom opening of the separation chamber 11.

[0048] Reference Figure 3 and Figure 4 The storage box is also equipped with a push-out mechanism 8, which includes a push-out frame 81 and a linkage component 82. The linkage component 82 includes a rotating frame 821, a driving frame 822, and a linkage member 823. The linkage member 823 includes a linkage frame 8231. The bottom of the push-out frame 81 is embedded in the top opening of the storage box 3 and is located at the end of the storage box 3 away from the end opening of the storage box 3 along its own length.

[0049] Reference Figure 3 and Figure 4 The bottom of the ejector 81 abuts against the inner bottom wall of the storage box 3, and the top extends out of the storage box 3 and extends to both sides in the width direction of the storage box 3. After extending, it bends downward so that the ejector 81 fits over the storage box 3. The ejector 81 is slidably connected to the outer wall of the storage box 3 through a sliding groove, and the sliding direction is the length direction of the storage box 3.

[0050] Reference Figure 3 and Figure 4 In this embodiment, two linkage components 82 are provided, located on opposite sides of the storage box 3 in the width direction. One end of each linkage frame 8231 is rotatably connected to the storage box 3 via a pin, and the rotatable connection point is different from the rotatable connection point of the storage box 3 itself. The other end of each linkage frame 8231 is rotatably connected to one end of a rotating frame 821 via a pin, and each rotating frame 821 is rotatably connected to the inner wall of the separation compartment 11 via a pin, and the rotatable connection point is different from the rotatable connection point with the linkage frame 8231.

[0051] Reference Figure 3 and Figure 4 Each rotating frame 821 is sleeved on a corresponding driving frame 822 and is slidably connected to the corresponding driving frame 822, with the sliding direction being the length direction of the driving frame 822. The bottom end of each driving frame 822 is rotatably connected to the end of the ejector frame 81 through a pin to drive the ejector frame 81 to slide.

[0052] Reference Figure 3 and Figure 4 In the initial state, when the storage box is closed to the bottom opening of the separation chamber 11, the ejector 81 is located at the end of its sliding path away from the end opening of the storage box 3. When the storage box 3 rotates, it causes the linkage frame 8231 to shift, which in turn causes the rotating frame 821 to rotate. During this process, the rotating frame 821 drives the drive frame 822 to rotate as well, and the drive frame 822 slides relative to the rotating frame 821 under the constraint of the ejector 81. This causes the drive frame 822 to drive the ejector 81 to slide, gradually bringing the ejector 81 closer to the end opening of the storage box 3, thereby gradually ejecting the impurities inside the storage box 3.

[0053] Reference Figure 3 and Figure 4 The storage box 3 is also equipped with a closing mechanism 9, which is used to close the opening at the end of the storage box 3. The closing mechanism 9 includes a closing frame 91 and a transmission component 92, the transmission component 92 including a transmission frame 921. The closing frame 91 is located inside the opening at the end of the storage box 3 and is used to close the opening at the end of the storage box 3. The top of the closing frame 91 is rotatably connected to the end of the storage box 3 by a pin.

[0054] Reference Figure 3 and Figure 4 In this embodiment, the number of transmission frames 921 is set to two, and they are arranged one-to-one with two rotating frames 821. One end of each rotating frame 821 is rotatably connected to the corresponding rotating frame 821 by a pin, and the rotatable connection point is different from the rotatable connection point of the rotating frame 821 itself. The other end of each rotating frame 821 is rotatably connected to the sealing frame 91 by a pin, and the rotatable connection point is different from the rotatable connection point of the sealing frame 91 itself.

[0055] Reference Figure 3 and Figure 4In the initial state, when the storage box 3 is closed to the bottom opening of the separation chamber 11, the sealing frame 91 is also closed to the end opening of the storage box 3. When the storage box 3 rotates, it causes the linkage frame 8231 to shift, which in turn causes the rotating frame 821 to rotate. During this process, the rotating frame 821 causes the transmission frame 921 to shift, which in turn causes the end of the transmission frame 921 to rotate the sealing frame 91. This gradually opens the end opening of the storage box 3, allowing impurities inside the storage box 3 to escape through the end opening.

[0056] Reference Figure 3 and Figure 4 In this embodiment, a locking mechanism 10 is also provided at the bottom of the separation compartment 11. The locking mechanism 10 includes a locking frame 101 and a return spring 102. One end of the locking frame 101 is inserted into the bottom of the storage box 3 via the outside and inner wall of the separation compartment 11, and is slidably connected to the separation compartment 11, with the sliding direction parallel to the rotation axis of the storage box 3. The other end of the locking frame 101 is located outside the separation compartment 11 for workers to pull out.

[0057] Reference Figure 3 and Figure 4 Each locking bracket 101 has a guide surface at one end inserted into the storage box 3. After the bottom outer wall of the storage box 3 contacts the guide surface on the locking bracket 101, the locking bracket 101 is pushed to slide, making room for the storage box 3. Each return spring 102 is sleeved on the corresponding locking bracket 101, with one end abutting against the locking bracket 101 and the other end abutting against the inner wall of the separation compartment 11, so that the locking bracket 101 is continuously inserted into the storage box 3 by its own elasticity.

[0058] The implementation principle of the impurity removal device for cotton fibers in Embodiment 2 of this application is as follows: When the storage box 3 rotates, the storage box 3 drives the linkage frame 8231 to move, thereby causing the linkage frame 8231 to drive the rotating frame 821 to rotate. During this process, the rotating frame 821 drives the drive frame 822 to rotate together, and the drive frame 822 slides relative to the rotating frame 821 under the restriction of the push-out frame 81, thereby causing the drive frame 822 to drive the push-out frame 81 to slide, so that the push-out frame 81 gradually approaches the opening at the end of the storage box 3, thereby gradually pushing out the impurities in the storage box 3.

[0059] During this process, the rotation of the rotating frame 821 causes the transmission frame 921 to shift, which in turn causes the end of the transmission frame 921 to rotate the closing frame 91, thereby causing the opening at the end of the storage box 3 to gradually open, allowing impurities inside the storage box 3 to pass through the opening at the end of the storage box 3.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
