Detailed Implementation

[0033] To make the objectives, methods, and advantages of the embodiments of the present invention clearer, the methods in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0034] During the textile spinning process, fiber breakage is inevitable due to the characteristics of some fibers. Current technology typically uses negative pressure equipment to generate suction and draw the broken fibers into a collection box. A suction port is located at the bottom of the collection box. However, if the textile dust collection equipment or the factory suddenly loses power, the suction of the negative pressure equipment will suddenly disappear. The broken fibers that have already accumulated at the suction port with the airflow will suddenly lose suction and may fall back, especially those with increased volume. To achieve targeted dust collection, the suction port of the collection box is often located above the textile machine, which may cause the broken fibers to fall back onto the surface of the textile fibers, affecting subsequent production operations. To avoid the impact of broken fibers accumulating on the surface of the textile fibers, the fiber surface often needs to be cleaned after power is restored, which is a cumbersome operation. See patent publication number CN118668342A, which designs an extension chamber that extends downwards under the action of a counterweight frame after a power outage. This extension chamber encloses the dust accumulated at the suction port, and then a power storage device rotates an electric louver to seal the bottom of the extension chamber. However, once the extended chamber is completely sealed, the air does not circulate, and the broken fibers easily accumulate and fall onto the surface of the louvers. When the power is turned on and the louvers open, the broken fibers may fall back onto the textile machine. If the textile machine continues its operation before the power outage after being powered on, the fallen broken fibers may not be sucked away in time, which may affect subsequent processes or products. In order to solve the aforementioned problems, the applicant has conceived the following technical solution.

[0035] Example 1: As Figure 1-3 As shown, a dust removal device includes: a collection box 1, rotating rollers 2, a filter ring belt 3, a connecting cylinder 4, a mesh cylinder 5, a counterweight frame 6, a sealing assembly 7, and a force application assembly 8; the top wall of the collection box 1 is provided with a suction port 101, which is used to communicate with a negative pressure device; the bottom wall of the collection box 1 is provided with an opening 102, and the side wall of the collection box 1 is provided with a flow channel 103, the upper opening of which is located on the inner wall of the collection box 1; the inner wall of the collection box 1 is connected to a plurality of rotating rollers 2; the filter ring belt 3 is sleeved on a plurality of rotating rollers 2; when the rotating rollers 2 rotate, they drive the filter ring belt 3 to rotate in the vertical plane; the connecting cylinder 4 passes through the opening 102 and is slidably connected to the inner wall of the collection box 1; the mesh cylinder 5... The top wall of the mesh cylinder 5 is connected to the bottom wall of the connecting cylinder 4; the diameter of the cross-section of the mesh cylinder 5 gradually increases as the mesh cylinder 5 extends away from the connecting cylinder 4; the shape of the outer wall of the mesh cylinder 5 matches the shape of the lower opening of the flow channel 103; when the outer wall of the mesh cylinder 5 abuts against the collection box 1, there is a gap between the outer wall of the connecting cylinder 4 and the upper opening of the flow channel 103; the bottom wall of the mesh cylinder 5 is connected to the counterweight frame 6; the inner wall of the counterweight frame 6 is provided with a sealing component 7, which is used to close the lower opening of the counterweight frame 6; the force-applying component 8 is connected to the counterweight frame 6 or the sealing component 7; when the power is off, the traction force of the force-applying component 8 on the counterweight frame 6 is lost, and the sealing component 7 can be opened when the force-applying component 8 applies force.

[0036] In practical implementation, the filter ring belt 3 can be made of metal, such as stainless steel, or plastic, such as polyester fiber. To increase the electrostatic adsorption of broken lint by the filter ring belt 3, it can be made of polystyrene or polypropylene. The bottom wall of the outer wall of the mesh cylinder 5 can be as follows: Figure 3 As shown, it is set as a bevel cut in order to achieve the following: Figure 2 As shown, the outer wall of the mesh cylinder 5 is covered with a beveled cut. This is to prevent the connecting cylinder 4 from being... Figure 2 In the indicated state, the upper opening of the flow channel 103 is completely blocked, and the length of the connecting cylinder 4 needs to be limited. When energized, the force-applying component 8 pulls up the counterweight frame 6; when de-energized, the force exerted by the force-applying component 8 on the counterweight frame 6 disappears. There are various structures for the force-applying component 8 that can satisfy both of the aforementioned conditions, such as using the magnetic force of an electromagnet to fix the position of the counterweight frame 6. When de-energized, the magnetic force disappears, and the counterweight frame 6 falls. The rotating roller 2 can be as follows... Figure 1 As shown, four are set up and arranged in a rectangular pattern on the vertical plane.

[0037] like Figure 3 As shown, when the power is off, under the action of the counterweight frame 6, the connecting cylinder 4 moves downward, covering the broken fibers gathered below the counterweight frame 6. After the lower end of the counterweight frame 6 is sealed by the sealing component 7, the broken fibers are captured. At the same time, due to the presence of the mesh cylinder 5, air can circulate inside and outside the device, thereby reducing the amount of broken fibers falling back to the inner surface of the sealing component 7.

[0038] like Figure 2 As shown, after power is applied, under the action of the force-applying component 8, the counterweight frame 6 moves upward until the outer wall of the mesh cylinder 5 abuts against the lower opening of the flow channel 103. When the negative pressure device is activated for suction, the broken fibers above the textile machine enter through the lower opening of the counterweight frame 6 and are adsorbed onto the filter ring belt 3. Driven by the rotating roller 2, the broken fibers on the filter ring belt 3 move to the suction port 101 and are sucked away. Figure 3 In this state, some broken fibers may adhere to the outer wall of the mesh cylinder 5, especially during a sudden power outage. Due to the lower pressure inside the mesh cylinder 5, the outer wall of the mesh cylinder 5 is exposed during the descent of the counterweight frame 6. Under the pressure difference, air flows from the outer wall of the mesh cylinder 5 into the inside of the mesh cylinder 5, making it easier for broken fibers to adhere to the outer wall of the mesh cylinder 5. Figure 2 When in this state, the broken fibers on the outer wall of the mesh cylinder 5 will enter the collection box 1 under the action of suction, thereby cleaning the outer wall of the mesh cylinder 5.

[0039] Example 2: To avoid the impact of broken fibers on the use of the sliding structure between the connecting cylinder 4 and the collecting box 1, improvements were made based on Example 1, such as... Figure 4As shown, in this embodiment, the inner wall of the collection box 1 is provided with a groove 104, and the outer wall of the connecting cylinder 4 is provided with a slider 401 that cooperates with the groove 104; when the connecting cylinder 4 is in any position, the outer wall of the connecting cylinder 4 covers the groove opening of the groove 104.

[0040] In the specific implementation process, the sliding structure of the groove 104 and the slider 401 is existing technology. Sliding damping can be set to reduce the falling speed of the connecting cylinder 4 without affecting the power outage. If part of the groove opening of the groove 104 is exposed after the counterweight frame 6 falls, broken fibers may enter the groove 104, affecting the use of the sliding structure.

[0041] Example 3: To improve the dust removal effect, improvements were made based on Example 1, such as... Figure 2 As shown, this embodiment includes: a partition 9, a spray mechanism 10, and a dust collection tank 11; the partition 9 is disposed inside the collection box 1, dividing the collection box 1 into a negative pressure zone 105 and a clean zone 106; the partition 9 has an opening 901 for the filter ring belt 3 to pass through, and the suction port 101 is disposed in the negative pressure zone 105; the clean zone 106 is provided with the spray mechanism 10, which is located in the enclosed area of ​​the filter ring belt 3; the dust collection tank 11 is disposed below the spray mechanism 10, and at least a portion of the filter ring belt 3 is located between the spray mechanism 10 and the dust collection tank 11, with the lower section of the filter ring belt 3 moving from the negative pressure zone 105 to the clean zone 106.

[0042] In the specific implementation process, the broken lint adheres to the filter ring belt 3 under the action of suction, and then moves to the cleaning zone 106 with the filter ring belt 3. Under the action of the spray mechanism 10, the broken lint on the filter ring belt 3 is washed into the dust collection tank 11. Water can eliminate the electrostatic interaction between the filter ring belt 3 and the broken lint, and then carry the broken lint into the dust collection tank 11. The spray mechanism 10 can use jet nozzles, and the force of the jet nozzles makes the cleaning more thorough. The broken lint remaining under the action of the spray mechanism 10 can be carried by the filter ring belt 3 to the suction port 101 for further removal. Cleaning the broken lint with the spray mechanism 10 before the suction port 101 can reduce the dust discharge work of the suction negative pressure device, and at the same time reduce the clogging of the suction port 101 and the connected pipe by broken lint. A vent can be provided on the side wall of the cleaning zone 106 of the collection box 1. The vent should not be too large to prevent external broken lint from entering directly, and it should be sufficient to balance the internal and external pressure of the cleaning zone 106.

[0043] Example 4: In order to save water resources, improvements were made based on Example 3, such as... Figure 2As shown, in this embodiment, the dust collection tank 11 is provided with a water outlet pipe 1101 and an overflow pipe 1102. The overflow pipe 1102 is higher than the water outlet pipe 1101. The water outlet pipe 1101 is connected to the spraying mechanism 10 through a water pump. The dust collection tank 11 is provided with a water level sensor. The water outlet pipe 1101 is connected to the water supply pipe 13 through a three-way valve 12.

[0044] In the specific implementation process, during the cleaning process of the spray mechanism 10, the water in the dust collection tank 11 gradually increases. Since the density of the broken fibers is relatively low, most of them float on the water surface. Therefore, the broken fibers continue to rise with the water level. When the water level reaches the height of the overflow pipe 1102, the broken fibers are discharged from the overflow pipe 1102 along with the water. A water level sensor is installed in the dust collection tank 11 to monitor the water level at all times. Simultaneously, in order to increase the amount of broken fibers carried away per unit volume of water and reduce water waste, this embodiment achieves water reuse in the dust collection tank 11 through the cooperation of the water outlet pipe 1101, the water pump, and the spray mechanism 10, thereby controlling the water level in the integrated tank, controlling the amount of broken fibers in the tank, and thus controlling the amount of broken fibers carried away per unit volume of water in the overflow pipe 1102. When the water volume in the integrated tank is insufficient to meet the overflow, water can be added through the water replenishment pipe 13 to increase the total water volume circulating between the integrated tank and the spray mechanism 10.

[0045] Example 5: To achieve automatic closing of the sealing assembly 7 in the event of a power outage, improvements were made based on Examples 1-4, such as... Figure 5-8 As shown, in this embodiment, the counterweight frame 6 is provided with a limiting part, and the sealing assembly 7 includes: a blade 701, a sprocket 702, a chain 703, and a counterweight block 704; the blade 701 is rotatably connected to the inner wall of the counterweight frame 6 through a connecting shaft 705; the connecting shaft 705 is provided with the sprocket 702; the chain 703 is drivenly connected to the sprocket 702, and a limiting plate 7031 is provided at the end of the chain 703; one end of the chain 703 passes through the limiting part and is connected to the counterweight block 704, and the limiting part is located between the limiting plate 7031 and the counterweight block 704; the force-applying assembly 8 is connected to the other end of the chain 703.

[0046] In the specific implementation process, the counterweight frame 6 can be referred to Figure 5 The diagram shows a through hole through which the force-applying component 8 passes and connects to the chain 703. When powered on, the negative pressure device is activated, and the counterweight 704 is in the following state: Figure 6 As shown, blade 701 is also in the same position. Figure 5In the open state shown, airborne lint can enter the collection box 1 through the gaps between the blades 701. After power failure, the pulling force of the force-applying component 8 on the counterweight 704 is suddenly lost. Under the gravity of the counterweight frame 6, the connecting cylinder 4 slides downward, covering the airborne lint in the space below the collection box 1. When the counterweight frame 6 reaches its maximum displacement, it can no longer descend. Figure 7 As shown, under the gravity of the counterweight 704, the chain 703 moves, driving the sprocket 702 to rotate, which in turn drives the blade 701 to rotate to the closed position. The closed state of the blade 701 can be seen in [reference needed]. Figure 10 As shown. The position of the limit plate 7031 can be determined according to the distance the chain 703 needs to move when the blade 701 switches between opening and closing. The blade 701 can be seen in [reference needed]. Figure 8 As shown, a sprocket 702 is installed at one or both ends of the connecting shaft 705. If sprockets 702 are installed at both ends of the same connecting shaft 705, a chain 703 and a force-applying component 8 can be installed respectively.

[0047] The dust removal device provided in this embodiment can rotate the blades 701 even when the power is completely off, thanks to the counterweight 704. To make it easier for the counterweight 704 to drive the chain 703 and sprocket 702, the connecting shaft 705 and blades 701 can be made of lightweight plastic.

[0048] The limiting part is used to limit the maximum downward movement of the limiting plate 7031 and the maximum upward movement of the counterweight block 704. The limiting part can be formed by additionally setting a plate on the counterweight frame 6, or it can be formed by the structure of the counterweight frame 6 itself.

[0049] Exemplary, such as Figure 6-7 As shown, in this embodiment, the side wall of the counterweight frame 6 is provided with a cavity 601, the limiting plate 7031 is housed in the cavity 601, one end of the chain 703 passes through the cavity 601 and is connected to the counterweight block 704, and at least a portion of the orthographic projection of the side wall of the counterweight frame 6 in the vertical downward direction falls on the surface of the counterweight block 704.

[0050] The bottom wall of the counterweight frame 6 serves as the limiting part. It can be as follows: Figure 6 As shown, the top wall of the counterweight 704 is designed as a horizontal wall that mates with the limiting part. During vacuuming, the top wall of the counterweight 704 abuts against the limiting part. After power is cut off, the counterweight 704 falls, causing the limiting plate 7031 to... Figure 7 As shown, it moves down until it comes into contact with the limiting part.

[0051] Example 6: To avoid or reduce the disengagement between chain 703 and sprocket 702, improvements were made based on Example 5, such as... Figure 7 and Figure 9As shown, in this embodiment, the winding directions of the chains 703 on adjacent sprockets 702 are opposite, and the inner wall of the counterweight frame 6 is provided with a limiting roller 14. The end of the chain 703 near the counterweight block 704 is wound around the limiting roller 14.

[0052] In the specific implementation process Figure 9 Only two sprockets 702 are shown; subsequent sprockets 702 can be found by referring to [the previous examples]. Figure 9 The chain 703 is connected to the drive via a winding method. The S-shaped winding method reduces the possibility of the chain 703 disengaging from the sprocket 702.

[0053] The limiting roller 14 makes it easier to ensure that the end of the chain 703 is vertically downward. During the process of the counterweight 704 pulling the chain 703 or the chain 703 pulling the counterweight 704, the interaction force between the chain 703 and the limiting part is smaller. Without the limiting roller 14, the end of the chain 703 extends downward after winding around the last sprocket 702. If it were to remain vertically downward, the position of the limiting part would inevitably obstruct the blade 701. Therefore, the limiting roller 14 also allows the limiting part to be kept away from the end blade 701.

[0054] Example 7: To improve the levelness and stability of the counterweight frame 6 during its ascent, improvements were made based on Example 5, such as... Figure 11-12 As shown, in this embodiment, the counterweight frame 6 is provided with a plurality of connecting shafts 705. The plurality of connecting shafts 705 include a first connecting group 15 and a second connecting group 16. The sprockets 702 configured in the first connecting group 15 and the second connecting group 16 are staggered in the length direction of the connecting shafts 705. Both the first connecting group 15 and the second connecting group 16 are provided with chains 703 and counterweights 704 are configured at the ends of the chains 703.

[0055] In the specific implementation process, such as Figure 5 As shown, if the rotation of all blades 701 is achieved through the cooperation of only one counterweight 704 and chain 703, the end of the right force-applying component 8 is fixedly connected to the top wall of the counterweight frame 6. During the process of the counterweight frame 6 rising as the force-applying component 8 pulls upward, the left force-applying component 8 will first pull the counterweight 704 upward to abut against the limiting part, and then lift the left end of the counterweight frame 6. The right force-applying component 8 will directly pull the right end of the counterweight frame 6 upward. Thus, although the counterweight 704 can remain horizontal at the end of the rise, it may tilt during the rise. Therefore, in this embodiment, the blades 701, the corresponding connecting shafts 705 and sprockets 702 are divided into two groups. For example, the connecting shafts 705 on the left are one group, assumed to be the first connecting group 15; the connecting shafts 705 on the right are another group, assumed to be the second connecting group 16. Figure 11-12As shown, after setting counterweights 704 at both ends of the counterweight frame 6, the left counterweight 704 can cooperate with the second connecting group 16 and the right force application component 8 to achieve the rotation of the right blade 701. The right counterweight 704 cooperates with the first connecting group 15 and the left rope 801 to achieve the rotation of the left blade 701.

[0056] During the upward movement of the counterweight frame 6, the force-applying components 8 on both sides first pull the counterweight block 704 upward, and then pull the counterweight frame 6 upward, thereby improving the levelness and stability of the counterweight frame 6 during the upward movement.

[0057] Example 9: In order to achieve the application of force at both ends of the counterweight frame 6 using only one drive device 804, an improvement was made based on Example 5, such as... Figure 13-14 As shown, in this embodiment, the force-applying component 8 includes: a rope body 801, a rope take-up reel 802, a rotating shaft 803, a drive device 804, and an electromagnetic clutch 805; the rope body 801 is connected to the end of the chain 703; one end of the rope body 801 away from the chain 703 is connected to the rope take-up reel 802; the rope take-up reel 802 is disposed on the rotating shaft 803; the drive device 804 is connected to the rotating shaft 803; and the electromagnetic clutch 805 is connected to the drive device 804.

[0058] In the specific implementation process, such as Figure 2 As shown, the end of the chain 703 near the counterweight 704 can also be composed of a rope 801. The rope winding reel 802, the rotating shaft 803, the drive device 804, and the electromagnetic clutch 805 can all be located on the top of the collection box 1, avoiding the suction port 101. The drive device 804 can be a rotary motor. When energized, the rotating shaft 803 is connected to the drive device 804 via the electromagnetic clutch 805. When the output shaft of the drive device 804 rotates, it drives the rotating shaft 803 to rotate, thereby driving the rope winding reel 802 to wind and unwind the rope 801, and adjusting the height of the counterweight by moving the rope 801. In the event of a sudden power outage, the electromagnetic clutch 805 fails, the connection between the rotating shaft 803 and the drive device 804 is broken, and the rotating shaft 803 is in a free-moving state. Under the action of the counterweight, the rope 801 moves downwards, driving the rotating shaft 803 to rotate.

[0059] The ropes 801 on both sides of the counterweight can be driven by independent drive devices 804 to wind and unwind. However, in order to reduce the number of drive devices 804 and improve the synchronization of the winding and unwinding of the ropes 801, this embodiment uses the cooperation of pulleys and a transmission belt to achieve the transmission between the first shaft 8031 ​​and the second shaft 8032. Figure 14As shown, the second shaft 8032 is connected to the drive device 804. When the output shaft of the drive device 804 rotates, it drives the second shaft 8032 to rotate, and the second shaft 8032 drives the first shaft 8031 ​​to rotate. In turn, the rope body 801 is synchronously wound and unwound through the rope winding disc 802 on the first shaft 8031 ​​and the second shaft 8032.

[0060] In order to make it easier for the counterweight 704 to drive the connecting shaft 705 to rotate, two adjacent connecting shafts 705 in the first connecting group 15 or the second connecting group 16 are provided with sprockets 7024, and the remaining connecting shafts 705 are connected to their adjacent connecting shafts 705 by gear transmission.

[0061] If each connecting shaft 705 is equipped with a sprocket 702, and the chain 703 is wound around each sprocket 702 in an S-shape to achieve transmission engagement, the possibility of the chain 703 disengaging from the sprocket 702 increases. Therefore, in this embodiment, each chain 703 only engages with two sprockets 702, and a gear is additionally provided on the connecting shaft 705. The remaining connecting shafts 705 without sprockets 702 are connected by gears, and the connecting shafts 705 adjacent to the connecting shafts 705 of the connecting sprockets 702 are also connected by gears to the connecting shafts 705 of the connecting sprockets 702.

[0062] As an example, the sprockets 702 are all set on the connecting shafts 705 at both ends, and the connecting shaft 705 in the middle is connected by gear transmission. The two ends of the chain 703 can be equipped with limit rollers 14 to achieve the tensioning of the chain 703.

[0063] Example 10: This example provides a method of using a dust removal device. After power is applied, the reset operation of the counterweight frame 6 includes: first turning on the negative pressure device, and then pulling the counterweight frame 6 up through the force application component 8 until the mesh cylinder 5 abuts against the collection box 1.

[0064] In practice, after a power outage, the collected lint may fall back onto the inner surface of the sealing component 7. If the sealing component 7 opens directly after power is restored, the collected lint may fall onto the surface of the textile machine, affecting subsequent textile operations. Therefore, in the reset operation of this embodiment, the negative pressure device is first activated to generate a certain suction force to pick up the lint from the surface of the sealing component 7, and then the counterweight frame 6 is pulled. In addition, the sealing component 7 used in this invention is not electrically driven and will automatically open during the process of the force application component 8 pulling up the counterweight frame 6. Thus, when using the sealing component 7 provided by this invention, the blade 701 opens before the counterweight frame 6 rises, making it even more necessary to activate the negative pressure device first to prevent the lint on the inner surface of the blade 701 from falling back onto the textile machine the moment the blade 701 opens.

[0065] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
