DETAILED DESCRIPTION

[0033] In order to make the purpose, method scheme and advantages of the embodiments of the present invention clearer, the method scheme in the embodiments of the present invention is clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] In the weaving process of the textile machine, it is inevitable that some fibers will break due to the characteristics of the fibers. Therefore, the prior art usually uses a negative pressure device to generate suction to suck the broken fibers into the collection box. A dust suction port is provided below the collection box. However, if the textile dust collection device or the factory area suddenly loses power, the suction of the negative pressure device will suddenly disappear, and the broken fibers that have previously gathered at the dust suction port with the airflow will suddenly lose suction and may fall back, especially because of the increased volume of the broken fibers. In order to achieve fixed-point dust suction, the dust suction port of the collection box is often located above the textile machine, so that the broken fibers may fall back to the surface of the textile fibers, affecting subsequent production operations. In order to avoid the influence of the accumulation of broken fibers on the surface of the textile fibers, it is often necessary to clean the fiber surface after power is turned on, and the operation is relatively cumbersome. Referring to the patent with publication number CN118668342A, it designs an extension bin that can extend downward under the action of a counterweight frame after power failure, and covers the dust gathered at the dust suction port in the extension bin, and then the bottom of the extension bin is closed by rotating the electric shutter through the storage device. However, after the interior of the extension chamber is completely closed, the air does not circulate, and the broken fibers are easily gathered and fall on the surface of the louver. When the power is turned on and the louver is opened, the broken fibers may fall back to the textile machine. If the textile machine automatically continues the operation before the power outage after the power is turned on, the fallen broken fibers may not be sucked away in time, which may affect the subsequent processes or products. In order to solve the aforementioned problems, the applicant has conceived the following technical solution.

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

[0036] In the specific implementation process, the filter belt 3 can be made of metal material such as stainless steel, or plastic material such as polyester fiber. In order to increase the electrostatic adsorption effect of the filter belt 3 on the broken fibers, the filter belt 3 can be made of polystyrene or polypropylene. The bottom wall of the outer wall of the net tube 5 can be as Figure 3 As shown, the cut is set to be oblique so as to achieve the following Figure 2 As shown, the outer wall of the net tube 5 covers the oblique cut. In order to avoid the connection tube 4 in the Figure 2 In the state shown, the upper opening of the flow channel 103 is completely blocked, and the length of the connecting tube 4 needs to be limited. When the power is on, the force-applying component 8 is used to pull up the counterweight frame 6; when the power is off, the force applied by the force-applying component 8 on the counterweight frame 6 disappears. There are many structures of the force-applying component 8 that can meet the above two situations, such as using the magnetic force of an electromagnet to fix the position of the counterweight frame 6. When the power is off, the magnetic force disappears and the counterweight frame 6 falls. The rotating roller 2 can be as Figure 1 As shown, four are provided and arranged in a rectangular shape on a 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 to cover the broken flocs gathered below the counterweight frame 6, and the lower end of the counterweight frame 6 is sealed by the sealing component 7, thereby achieving the capture of the broken flocs. At the same time, due to the existence of the net cylinder 5, the air inside and outside the device can circulate, thereby reducing the broken flocs in the device from falling back to the inner surface of the sealing component 7.

[0038] like Figure 2 As shown, after power is turned on, under the action of the force-applying assembly 8, the counterweight frame 6 moves upward until the outer wall of the net tube 5 abuts against the lower opening of the flow channel 103. When the negative pressure device is started for suction, the broken cotton wool above the textile machine enters from the lower opening of the counterweight frame 6 and is adsorbed on the filter ring belt 3. Driven by the rotating roller 2, the broken cotton wool on the filter ring belt 3 moves to the suction port 101 and is sucked away. Figure 3 In the state, some broken fibers may adhere to the outer wall of the net tube 5, especially when the power is suddenly cut off. Since the pressure inside the net tube 5 is relatively small, the outer wall of the net tube 5 is exposed during the falling process of the counterweight frame 6. Under the action of the pressure difference, the air on the outer wall of the net tube 5 flows into the net tube 5, and the broken fibers are easy to adhere to the outer wall of the net tube 5. Figure 2 In the state, the broken fibers on the outer wall of the net tube 5 will enter the collection box 1 under the action of suction, thereby cleaning the outer wall of the net tube 5.

[0039] Embodiment 2: In order to prevent the broken cotton from affecting the use of the sliding structure between the connecting tube 4 and the collecting box 1, an improvement is made on the basis of Embodiment 1, such as Figure 4As shown, in this embodiment, the inner wall of the collecting box 1 is provided with a slide groove 104, and the outer wall of the connecting tube 4 is provided with a slider 401 cooperating with the slide groove 104; when the connecting tube 4 is in any position, the outer wall of the connecting tube 4 covers the notch of the slide groove 104.

[0040] In the specific implementation process, the sliding structure of the slide groove 104 and the slider 401 is the prior art, and a sliding damping can be set to reduce the falling speed of the connecting tube 4 without affecting the connection tube 4 falling when the power is off. If the notch of the slide groove 104 is partially exposed after the counterweight frame 6 falls, the broken cotton may enter the slide groove 104, affecting the use of the sliding structure.

[0041] Embodiment 3: In order to improve the dust removal effect, improvements are made on the basis of Embodiment 1, such as Figure 2 As shown, in this embodiment, it includes: a partition 9, a spray mechanism 10 and a dust collecting tank 11; the partition 9 is arranged in the collecting box 1, and divides the collecting box 1 into a negative pressure zone 105 and a clean zone 106, the partition 9 is provided with an opening 901 for the filter ring belt 3 to pass through, and the suction port 101 is arranged in the negative pressure zone 105; the clean zone 106 is provided with the spray mechanism 10, and the spray mechanism 10 is located in the enclosed area of ​​the filter ring belt 3; the dust collecting tank 11 is arranged below the spray mechanism 10, and at least a part of the filter ring belt 3 is located between the spray mechanism 10 and the dust collecting tank 11, and the lower section of the filter ring belt 3 moves from the negative pressure zone 105 to the clean zone 106.

[0042] During the specific implementation process, the broken flocs are attached to the filter belt 3 under the action of suction, and then move to the cleaning area 106 with the filter belt 3. Under the action of the spray mechanism 10, the broken flocs on the filter belt 3 are washed into the dust collecting tank 11. Water can eliminate the electrostatic effect between the filter belt 3 and the broken flocs, and then carry the broken flocs to the dust collecting tank 11. The spray mechanism 10 can use a jet nozzle, and the impact of the jet nozzle can make the cleaning more thorough. The broken flocs remaining under the action of the spray mechanism 10 can also continue to be brought to the suction port 101 by the filter belt 3 for further removal. Before the suction port 101, the spray mechanism 10 is used to clean the broken flocs, which can reduce the dust removal work of the suction negative pressure device and reduce the blockage of the suction port 101 and the pipe body connected thereto by the broken flocs. A vent can be set on the side wall of the cleaning area 106 of the collecting box 1. The vent is not easy to be too large to prevent the external broken flocs from directly entering, and can meet the balance of the internal and external pressures of the cleaning area 106.

[0043] Embodiment 4: In order to save water resources, improvements are made on the basis of Embodiment 3, such as Figure 2As shown, in this embodiment, the dust collecting 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 spray mechanism 10 through a water pump, the dust collecting tank 11 is provided with a water level sensor, and 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 collecting tank 11 will gradually increase, and the density of the broken flocs is relatively small, and most of them float on the water surface, so the broken flocs will continue to rise with the rise of the water surface. When the water surface reaches the height of the overflow pipe 1102, the broken flocs will be discharged from the overflow pipe 1102 along with the water. A water level sensor is set in the dust collecting tank 11 to monitor the water level of the dust collecting tank 11 at all times. At the same time, in order to increase the amount of broken flocs carried away by a unit volume of water and reduce the waste of water resources, this embodiment realizes the reuse of water in the dust collecting tank 11 through the cooperation of the water outlet pipe 1101, the water pump and the spray mechanism 10, thereby controlling the water level of the integrated tank, and then controlling the amount of broken flocs in the tank, and then controlling the amount of broken flocs carried away by a unit volume of water in the overflow pipe 1102. When the amount of water in the integrated tank is difficult to meet the overflow of water, water can be supplemented through the water supply pipe 13 to increase the total amount of water circulating between the integrated tank and the spray mechanism 10.

[0045] Embodiment 5: In order to realize the automatic closing of the sealing assembly 7 in case of power failure, improvements are made on the basis of embodiments 1-4, such as Figure 5-8 As shown, in this embodiment, the counterweight frame 6 is provided with a limiting portion, 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 sprocket 702 is provided on the connecting shaft 705; the chain 703 is transmission-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 portion and is connected to the counterweight block 704, and the limiting portion 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 weight frame 6 can be seen in Figure 5 As shown in the figure, a through hole is provided, and the force-applying component 8 passes through the through hole and is connected to the chain 703. When the power is on, the negative pressure device is turned on, and the state of the counterweight block 704 is as follows: Figure 6 As shown, blade 701 is also in Figure 5In the open state shown, broken cotton in the air 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 block 704 is suddenly lost. Under the gravity of the counterweight frame 6, the connecting tube 4 slides downward to cover the broken cotton in the space below the collection box 1. When the counterweight frame 6 moves down to the maximum displacement, it cannot continue to descend. Figure 7 As shown, under the gravity of the counterweight 704, the chain 703 moves, driving the sprocket 702 to rotate, and then driving the blade 701 to rotate to close. The closed state of the blade 701 can be seen in FIG. Fig.10 The position of the limit plate 7031 can be determined according to the distance that the chain 703 needs to move when the blade 701 switches between opening and closing. Figure 8 As shown, it is arranged on the connecting shaft 705, and then a sprocket 702 is arranged at both ends or one end of the connecting shaft 705. If a sprocket 702 is arranged at both ends of the same connecting shaft 705, a chain 703 and a force applying component 8 can be arranged respectively.

[0047] The dust removal device provided in this embodiment can also realize the rotation of the blade 701 through the counterweight 704 when the power is completely off. In order to make it easier for the counterweight 704 to drive the chain 703 and the sprocket 702 to move, the connecting shaft 705 and the blade 701 can be made of lightweight plastic.

[0048] The limiting part is used to limit the maximum downward position of the limiting plate 7031 and the maximum upward position of the counterweight block 704. The limiting part can be composed of an additional plate body set on the counterweight frame 6, and can also be composed of 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 accommodated 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 part 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 side wall of the counterweight frame 6 is used as the limiting part. Figure 6 As shown, the top wall of the counterweight block 704 is set as a horizontal wall that cooperates with the limit part. During the dust collection process, the top wall of the counterweight block 704 abuts against the limit part. After the power is turned off, the counterweight block 704 falls, driving the limit plate 7031 as shown in FIG. Figure 7 As shown, it moves downward until it abuts against the limiting portion.

[0051] Embodiment 6: In order to avoid or reduce the separation between the chain 703 and the sprocket 702, an improvement is made on the basis of Embodiment 5, such as Figure 7 and Fig. 9As shown, in this embodiment, the winding directions of the chains 703 on adjacent sprockets 702 are opposite, a limiting roller 14 is provided on the inner wall of the counterweight frame 6, and one end of the chain 703 close to the counterweight block 704 is wound around the limiting roller 14.

[0052] During the specific implementation process, Fig. 9 Only two sprockets 702 are shown, and the subsequent sprockets 702 can refer to Fig. 9 The middle winding mode is connected with the chain 703. The possibility of the chain 703 being separated from the sprocket wheel 702 can be reduced by the S-shaped winding.

[0053] The limiting roller 14 makes it easier to achieve that the end of the chain 703 is vertically downward, and the interaction force between the chain 703 and the limiting part is smaller in the process of the counterweight 704 pulling the chain 703 or the chain 703 pulling the counterweight 704. If there is no limiting roller 14, the end of the chain 703 extends downward after being wound around the last sprocket 702. If it is to be kept vertically downward, the setting position of the limiting part will inevitably block the blade 701. Therefore, the setting of the limiting roller 14 can also make the limiting part away from the blade 701 at the end.

[0054] Embodiment 7: In order to improve the levelness and stability of the counterweight frame 6 during the rising process, improvements are made on the basis of Embodiment 5, such as Figure 11-12 As shown, in this embodiment, the counterweight frame 6 is provided with a plurality of connecting shafts 705, and the plurality of connecting shafts 705 include a first connecting group 15 and a second connecting group 16. The sprockets 702 configured with the first connecting group 15 and the second connecting group 16 are staggered in the length direction of the connecting shaft 705. The first connecting group 15 and the second connecting group 16 are both configured with the chains 703 and counterweight blocks 704 are both configured at the ends of the chains 703.

[0055] In the specific implementation process, Figure 5 As shown, if the rotation of all blades 701 is achieved only through the cooperation of one counterweight block 704 and the chain 703, the end of the right-side force-applying assembly 8 is fixedly connected to the top wall of the counterweight frame 6. When the force-applying assembly 8 is pulled up and the counterweight frame 6 rises, the left-side force-applying assembly 8 will first pull the counterweight block 704 up to abut against the limiting portion, and then lift the left end of the counterweight frame 6. The right-side force-applying assembly 8 directly pulls the right end of the counterweight frame 6 up, so that although the counterweight block 704 can remain horizontal at the end of the rise, it may tilt during the rise. Therefore, this embodiment divides the blades 701, the connecting shafts 705 corresponding to the blades 701, and the sprockets 702 into two groups. For example, the connecting shafts 705 on the left side are one group, assumed to be the first connecting group 15; the connecting shafts 705 on the right side are another group, assumed to be the second connecting group 16. As shown Figure 11-12As shown, after arranging the counterweight blocks 704 at both ends of the counterweight frame 6, the left counterweight block 704 cooperates with the second connection group 16 and the right force-applying assembly 8 to realize the rotation of the right blade 701. The right counterweight block 704 cooperates with the first connection group 15 and the left rope body 801 to realize the rotation of the left blade 701.

[0056] During the rising process 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 rising process.

[0057] Embodiment 9: In order to realize the force application at both ends of the counterweight frame 6 when only one driving device 804 is used, an improvement is made on the basis of Embodiment 5, such as Figure 13-14 As shown, in this embodiment, the force-applying component 8 includes: a rope body 801, a rope-collecting drum 802, a rotating shaft 803, a driving device 804 and an electromagnetic clutch 805; the rope body 801 is connected to the end of the chain 703; the end of the rope body 801 away from the chain 703 is connected to the rope-collecting drum 802; the rope-collecting drum 802 is arranged on the rotating shaft 803; the driving device 804 is connected to the rotating shaft 803; and the electromagnetic clutch 805 is connected to the driving device 804.

[0058] In the specific implementation process, Figure 2 As shown, one end of the chain 703 close to the counterweight 704 can also be composed of a rope body 801. The rope collecting disc 802, the rotating shaft 803, the driving device 804 and the electromagnetic clutch 805 can all be arranged on the top of the collection box 1, avoiding the suction port 101. The driving device 804 can use a rotating motor. In the power-on state, the rotating shaft 803 is connected to the driving device 804 through the electromagnetic clutch 805. When the output shaft of the driving device 804 rotates, the rotating shaft 803 can be driven to rotate, thereby driving the rope collecting disc 802 to retract and release the rope body 801, and adjusting the height of the counterweight seat by moving the rope body 801. When the power is suddenly cut off, the electromagnetic clutch 805 fails, the connection between the rotating shaft 803 and the driving device 804 is disconnected, and the rotating shaft 803 is in a free movable state. Under the action of the counterweight seat, the rope body 801 moves downward, driving the rotating shaft 803 to rotate.

[0059] The rope bodies 801 on both sides of the counterweight seat can be driven to be retracted and extended by independent driving devices 804. However, in order to reduce the number of driving devices 804 and improve the synchronization of the retraction and extension of the rope body 801, this embodiment realizes the transmission of the first shaft 8031 ​​and the second shaft 8032 through the cooperation of the pulley and the transmission belt. Fig.14As shown, the second shaft 8032 is connected to the driving device 804. When the output shaft of the driving device 804 rotates, the second shaft 8032 is driven to rotate, and the second shaft 8032 drives the first shaft 8031 ​​to rotate, and then the rope body 801 is synchronously retracted and released through the rope reel 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 through gear transmission.

[0061] If each connecting shaft 705 is provided with a sprocket 702, and the chain 703 is wound around each sprocket 702 in an S-shape to achieve transmission cooperation, the possibility of the chain 703 being separated from the sprocket 702 increases. Therefore, in this embodiment, each chain 703 is only matched with two sprockets 702, and then gears are additionally provided on the connecting shaft 705, and the remaining connecting shafts 705 without sprockets 702 are transmission-connected through gears, and the connecting shaft 705 adjacent to the connecting shaft 705 connected to the sprocket 702 is also transmission-connected to the connecting shaft 705 connected to the sprocket 702 through gears.

[0062] Exemplarily, the sprockets 702 are arranged on the connecting shafts 705 at both ends, and the middle connecting shaft 705 is connected through gear transmission. Limiting rollers 14 can be arranged at both ends of the chain 703 to achieve the tensioning of the chain 703.

[0063] Embodiment 10: This embodiment provides a method for using a dust removal device. After power is turned on, the resetting operation of the counterweight frame 6 includes: first turning on the negative pressure device, and then pulling up the counterweight frame 6 through the force-applying assembly 8 until the net cylinder 5 abuts against the collection box 1.

[0064] During the specific implementation process, after power failure, the broken cotton wool captured by the device may fall back to the inner surface of the sealing component 7. If the sealing component 7 is directly opened after power is turned on, the captured broken cotton wool may fall on the surface of the textile machine, affecting the subsequent textile work. Therefore, in the reset operation of this embodiment, the negative pressure device is first turned on to generate a certain suction force, which must suck up the broken cotton wool on the surface of the sealing component 7, and then the counterweight frame 6 is pulled. In addition, the sealing component 7 used in the present invention has no electric drive, and it will automatically open during the process of pulling the counterweight frame 6 on the force-applying component 8. Therefore, when the sealing component 7 provided by the present invention is used, the counterweight frame 6 has not risen yet, and the blade 701 has been opened. It is even more necessary to start the negative pressure device first to prevent the broken cotton wool on the inner surface of the blade 701 from falling back to the textile machine at the moment when the blade 701 is opened.

[0065] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
