DETAILED DESCRIPTION

[0030] 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, not all of the embodiments.

[0031] During the weaving process of a textile machine, it is inevitable that some fibers will break due to the characteristics of the fibers. Therefore, the existing technology usually uses a negative pressure device to generate suction to suck the broken fibers into a collection box. A dust suction port is provided below the collection box. However, if the textile dust collection equipment or the factory suddenly loses power, the suction of the negative pressure device will suddenly disappear, and the broken fibers that have previously accumulated in the dust suction port with the airflow will suddenly lose suction and may fall back, especially because the volume of the accumulated fibers increases. In order to achieve fixed-point dust collection, 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 impact 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, which is a relatively cumbersome operation. Referring to the patent with publication number CN118668342A, it designs an extension bin that can be extended downward under the action of a counterweight frame after power failure, so that the dust accumulated in the dust suction port is covered in the extension bin, and then the bottom of the extension bin is closed by rotating the electric shutter through the storage device. However, the opening and closing of electric blinds still require electricity. Therefore, in the case of a complete power outage, the extension chamber cannot be closed and the broken cotton in the extension chamber will still fall back. In order to solve the above problem, the applicant has conceived the following technical solution.

[0032] Example 1: Figure 1-6 As shown, a dust removal accessory includes: a counterweight seat 1, a blade 2, a sprocket 4, a chain 5, a counterweight block 6 and a rope body 7; the counterweight seat 1 is provided with a mounting groove 101, and the side wall of the counterweight seat 1 is provided with a limiting portion; the blade 2 is rotatably connected to the groove wall of the mounting groove 101 through a connecting shaft 3; the sprocket 4 is provided on the connecting shaft 3; the chain 5 is transmission-connected to the sprocket 4, and the end of the chain 5 is provided with a limiting plate 501; one end of the chain 5 passes through the limiting portion and is connected to the counterweight block 6, and the limiting portion is located between the limiting plate 501 and the counterweight block 6; the rope body 7 passes through the counterweight seat 1 and is connected to the other end of the chain 5.

[0033] In the specific implementation process, the counterweight seat 1 can be seen Figure 1 As shown, a through hole is provided, and the rope body 7 is connected to the chain 5 after passing through the through hole. The counterweight seat 1 is connected to the extension chamber of the textile dust collection device and its position is limited by the tension of the rope body 7. When the power is on, the collection device is turned on, and the state of the counterweight block 6 is as follows: Figure 2 As shown, blade 2 is also in Figure 1 In the open state shown, broken fibers in the air can enter the collection box through the gaps between the blades 2. After power is cut off, the tension at the end of the rope 7 away from the counterweight 6 is suddenly lost. Under the action of the gravity of the counterweight base 1, the rope 7 moves downward, and the extension chamber extends downward, covering the broken fibers in the space below the collection box. When the extension chamber is extended to the maximum extent, the counterweight base 1 cannot continue to descend. Figure 3As shown, under the gravity of the counterweight 6, the chain 5 moves, driving the sprocket 4 to rotate, and then driving the blade 2 to rotate to close. The closed state of the blade 2 can be seen in Figure 6 The position of the limit plate 501 can be determined according to the distance that the chain 5 needs to move when the blade 2 switches between opening and closing. Figure 5 As shown, it is arranged on the connecting shaft 3, and then sprockets 4 are arranged at both ends or one end of the connecting shaft 3. If sprockets 4 are arranged at both ends of the same connecting shaft 3, chains 5 and ropes 7 can be arranged respectively. Figure 2 As shown, the end of the chain 5 close to the counterweight 6 can also be composed of a rope body 7.

[0034] The dust removal accessory provided in this embodiment can also realize the rotation of the blade 2 through the counterweight 6 when the power is completely off. In order to make it easier for the counterweight 6 to drive the chain 5 and the sprocket 4 to move, the connecting shaft 3 and the blade 2 can be made of lightweight plastic.

[0035] The limiting portion is used to limit the maximum downward position of the limiting plate 501 and the maximum upward position of the counterweight block 6. There are many ways to set it, and you can also refer to the following two embodiments.

[0036] Implementation method 1: Figure 2 or Figure 3 As shown, the groove wall of the mounting groove 101 is provided with a cavity 1011, the limiting plate 501 is accommodated in the cavity 1011, one end of the chain 5 passes through the cavity 1011 and is connected to the counterweight block 6, and at least a part of the positive projection of the side wall of the counterweight seat 1 in the vertical downward direction falls on the surface of the counterweight block 6.

[0037] In the specific implementation process, the bottom wall of the side wall of the counterweight seat 1 is used as the limiting part. Figure 2 As shown, the top wall of the counterweight block 6 is set as a horizontal wall that cooperates with the limit part. During the dust collection process, the top wall of the counterweight block 6 abuts against the limit part. After the power is cut off, the counterweight block 6 falls, driving the limit plate 501 as shown in FIG. Figure 3 As shown, it moves downward until it abuts against the limiting portion.

[0038] Implementation method 2: Figure 4 As shown, the groove wall of the mounting groove 101 is connected to a baffle 1012, one end of the chain 5 passes through the baffle 1012 and is connected to the counterweight 6, and at least a part of the positive projection of the baffle 1012 in the vertical downward direction falls on the surface of the counterweight 6.

[0039] In the specific implementation process, Figure 4 As shown, a baffle 1012 is horizontally arranged, and the baffle 1012 serves as a limiting portion.

[0040] Example 2: In order to avoid or reduce the separation between the chain 5 and the sprocket 4, an improvement is made on the basis of Example 1, such as Figure 7 As shown, in this embodiment, the winding directions of the chains 5 on adjacent sprockets 4 are opposite.

[0041] During the specific implementation process, Figure 7 Only two sprockets 4 are shown, and the subsequent sprockets 4 can refer to Figure 7 The winding mode is connected with the chain 5 transmission. The possibility of the chain 5 breaking away from the sprocket 4 can be reduced by the S-shaped winding.

[0042] Example 3: In order to prevent the limiting portion from blocking the blade 2, an improvement is made based on Example 2, such as Figure 2-4 As shown, in this embodiment, a limiting roller 8 is provided on the groove wall of the installation groove 101 , and one end of the chain 5 close to the counterweight block 6 is wound around the limiting roller 8 .

[0043] During specific implementation, the limiting roller 8 makes it easier to achieve a vertical downward direction for the end of the chain 5. When the counterweight 6 pulls the chain 5 or the chain 5 pulls the counterweight 6, the interaction force between the chain 5 and the limiting portion is smaller. Without the limiting roller 8, the end of the chain 5 extends downward after being wound around the last sprocket 4. If it is to remain vertically downward, the location of the limiting portion will inevitably block the blade 2. Therefore, the provision of the limiting roller 8 can also keep the limiting portion away from the end of the blade 2.

[0044] Example 4: In order to improve the levelness and stability of the counterweight seat 1 during the rising process, improvements are made on the basis of Example 3, such as Figure 8-9 As shown, in this embodiment, the mounting groove 101 is provided with a plurality of the connecting shafts 3, and the plurality of the connecting shafts 3 include a first connecting group 301 and a second connecting group 32, and the sprockets 4 configured with the first connecting group 301 and the second connecting group 32 are staggered in the length direction of the connecting shaft 3, and the first connecting group 301 and the second connecting group 32 are both configured with the chains 5 and counterweights 6 are both configured at the ends of the chains 5.

[0045] In the specific implementation process, Figure 1As shown, if the rotation of all blades 2 is achieved by only one counterweight 6 and the chain 5, the end of the rope body 7 on the right is fixedly connected to the top wall of the counterweight seat 1. When the rope body 7 is pulled up and the counterweight seat 1 rises, the left rope body 7 will first pull the counterweight 6 up to abut against the limit part, and then lift the left end of the counterweight seat 1. The right rope body 7 directly pulls the right end of the counterweight seat 1 up, so that although the counterweight 6 can remain horizontal at the end of the rise, it may tilt during the rise. Therefore, this embodiment divides the blades 2, the connecting shafts 3 and the sprockets 4 corresponding to the blades 2 into two groups. For example, the connecting shafts 3 on the left are one group, which is assumed to be the first connection group 301; the connecting shafts 3 on the right are another group, which is assumed to be the second connection group 32. As shown Figure 8-9 As shown, after arranging the counterweight blocks 6 at both ends of the counterweight seat 1, the left counterweight block 6 can cooperate with the second connection group 32 and the right rope body 7 to realize the rotation of the right blade 2. The right counterweight block 6 cooperates with the first connection group 301 and the left rope body 7 to realize the rotation of the left blade 2.

[0046] During the rising process of the counterweight seat 1, the rope bodies 7 on both sides first pull the counterweight block 6 up, and then pull the counterweight seat 1 up, thereby improving the levelness and stability of the counterweight seat 1 during the rising process.

[0047] Example 5: In order to realize the automatic descent of the rope body 7 after power failure, an improvement is made on the basis of Example 4, such as Figure 10 As shown, in this embodiment, it includes: a rope collecting drum 9, a rotating shaft 10, a driving device 11, and an electromagnetic clutch 12; the end of the rope body 7 away from the chain 5 is connected to the rope collecting drum 9; the rope collecting drum 9 is arranged on the rotating shaft 10; the driving device 11 is connected to the rotating shaft 10; and the electromagnetic clutch 12 is connected to the driving device 11.

[0048] During the specific implementation process, the rope-collecting drum 9, the rotating shaft 10, the driving device 11 and the electromagnetic clutch 12 can all be arranged on the top of the existing equipment. The driving device 11 can be a rotating motor. When the power is on, the rotating shaft 10 is connected to the driving device 11 through the electromagnetic clutch 12. When the output shaft of the driving device 11 rotates, it can drive the rotating shaft 10 to rotate, thereby driving the rope-collecting drum 9 to retract and release the rope body 7, and adjust the height of the counterweight seat 1 by moving the rope body 7. In the event of a sudden power outage, the electromagnetic clutch 12 fails, the connection between the rotating shaft 10 and the driving device 11 is disconnected, and the rotating shaft 10 is in a free-moving state. Under the action of the counterweight seat 1, the rope body 7 moves downward, driving the rotating shaft 10 to rotate.

[0049] Example 6: In order to reduce the number of driving devices 11, an improvement is made on the basis of Example 5, such as Figure 11As shown, in this embodiment, the rotating shaft 10 includes a first shaft 1001 and a second shaft 1002. The first shaft 1001 and the second shaft 1002 are both provided with pulleys 13. The two pulleys 13 are connected by a transmission belt 14. The first shaft 1001 or the second shaft 1002 is connected to the driving device 11.

[0050] In the specific implementation process, the rope bodies 7 on both sides of the counterweight seat 1 can be driven to retract and extend by independent driving devices 11. However, in order to reduce the number of driving devices 11 and improve the synchronization of the retraction and extension of the rope bodies 7, this embodiment realizes the transmission of the first shaft 1001 and the second shaft 1002 through the cooperation of the pulley 13 and the transmission belt. Figure 11 As shown, the second shaft 1002 is connected to the driving device 11. When the output shaft of the driving device 11 rotates, it drives the second shaft 1002 to rotate, and the second shaft 1002 drives the first shaft 1001 to rotate, thereby realizing the synchronous retraction and release of the rope body 7 through the rope reel 9 on the first shaft 1001 and the second shaft 1002.

[0051] Example 7: In order to make it easier for the counterweight 6 to drive the connecting shaft 3 to rotate, improvements were made on the basis of Example 5. In this embodiment, two adjacent connecting shafts 3 in the first connecting group 301 or the second connecting group 32 are provided with sprockets 4, and the remaining connecting shafts 3 and their adjacent connecting shafts 3 are connected through gear transmission.

[0052] In a specific implementation, if each connecting shaft 3 is provided with a sprocket 4, and the chain 5 is wound around each sprocket 4 in an S-shaped manner to achieve transmission engagement, the possibility of the chain 5 being detached from the sprocket 4 increases. Therefore, in this embodiment, each chain 5 is engaged with only two sprockets 4, and additional gears are provided on the connecting shafts 3. The remaining connecting shafts 3 without sprockets 4 are transmission-connected via gears, and the connecting shafts 3 adjacent to the connecting shafts 3 connected to the sprockets 4 are also transmission-connected to the connecting shafts 3 connected to the sprockets 4 via gears.

[0053] Exemplarily, the sprockets 4 are arranged on the connecting shafts 3 at both ends, and the middle connecting shaft 3 is connected through gear transmission. Limiting rollers 8 can be provided at both ends of the chain 5 to achieve tensioning of the chain 5.

[0054] Example 8: Figure 1 As shown, in this embodiment, it includes: a telescopic cylinder 15, the upper end of the telescopic cylinder 15 is used to communicate with the internal space of the collection box, the lower end of the telescopic cylinder 15 is connected to the counterweight seat 1, and the internal space of the telescopic cylinder 15 is communicated with the internal space of the installation groove 101.

[0055] During the specific implementation process, the telescopic cylinder 15 can be made of a rigid material and slidably connected to the side wall of the collection box through the cooperation of a slide rail slider. The sliding connection structure can use damping to slow down the downward movement of the telescopic cylinder 15 without completely preventing the telescopic cylinder 15 from moving downward. The telescopic cylinder 15 can also use a bellows, and use the elasticity of the bellows itself to cooperate with the counterweight seat 1. The bellows is light in weight, so the counterweight does not need to be too high. After a power outage, even if the bellows stretches quickly, it will not affect other parts of the collection equipment too much. When the power is suddenly cut off, the lower end of the telescopic cylinder 15 moves downward under the action of the counterweight seat 1.

[0056] 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, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
