[0002] In the logistics of steel production, the safe storage and transportation of steel coils cannot be separated from reliable packaging and securing measures. Steel coil packing straps come in different widths to suit different specifications of steel coils. Currently, the most commonly used straps on site are 16mm and 19mm wide steel coils. 16mm wide packing straps are suitable for small steel coils weighing less than 5 tons, while 19mm wide straps are suitable for medium-sized steel coils weighing 5-10 tons.

[0003] Chinese patent CN103507981B discloses a steel coil packing strap release device, which fixes the packing strap by rotating the packing strap reel and releases steel coil packing straps of different lengths. The above device requires the packing strap reel to be disassembled before the packing strap can be fixed to the packing strap reel, which cannot achieve quick replacement of the packing strap.

[0004] Therefore, the problem in the existing technology is: how to propose a strapping release device that is compatible with the quick change of two different widths of strapping. Summary of the Invention

[0009] Furthermore, the transfer mechanism is equipped with a strapping storage mechanism and a strapping clamping mechanism on its side. Two strapping storage mechanisms are provided, each for storing strapping of different widths. The strapping clamping mechanism is used to move the strapping from the storage mechanism to the release mechanism. The strapping storage mechanism includes a feeding slide shaft, a feeding slide plate, and a storage box. The feeding slide shaft is located on both sides of the pit via shaft seats, and the feeding slide plate slides in sliding engagement with the feeding slide shaft via sliding sleeves. Feeding racks are located opposite each other on the lower side of the feeding slide plate. Feeding motors are located on both sides of the pit, and feeding gears are keyed to the motor shafts of the feeding motors, meshing with the feeding racks. The feeding slide has a stepped push plate channel in the middle, and a stepped feeding tray fits into the push plate channel. The lower side of the feeding slide has an upward moving base frame, and the lower side of the upward moving base frame has an upward moving push rod. The push head of the upward moving push rod passes upward through the upward moving base frame and is fixed to the lower side of the feeding tray. The storage box is set across the upper side of the feeding slide shaft by the support legs. The storage box has a rectangular box structure. The bottom of the storage box has a storage inlet with a circular cross section, and the side of the storage box has a storage outlet with a rectangular opening. The storage box is equipped with a spacer separation component, which is used to divide the three packing straps into equal intervals corresponding to the release chamber.

[0011] Furthermore, a covering component is provided on the lower side of the storage box. The covering component is used to cover the packing straps stacked on the feeding pallet. The covering component includes a covering drive motor and a corrugated protective cover on both sides. The covering drive motor on one side is fixed to the ground by a mounting plate, and the covering drive motor on the other side is fixed to the lower side of the storage box by a mounting plate. A covering sprocket is keyed to the motor shaft of the covering drive motor, and the two covering sprockets are connected by a synchronous chain. A covering drive slide shaft is vertically provided between the mounting plates on both sides. A covering drive slide plate is slidably fitted on the covering drive slide shaft. The covering drive slide plate is connected to the synchronous chain, and the synchronous chain drives the covering drive slide plate to slide up and down along the covering drive slide shaft.

[0014] Furthermore, the transfer mechanism includes a track arranged opposite to the track and a transfer motor fixed to the ground via a motor mount; a transfer sprocket is keyed to the motor shaft of the transfer motor, and the transfer sprockets on both sides are connected by a transfer chain drive; the transfer seat rolls with the track via track wheels, the transfer chain is fixed to the bottom of the transfer seat, and the transfer motor drives the transfer seat to move along the track in both forward and reverse directions.

[0015] The beneficial effects achieved by this invention are as follows: When it is necessary to replace the 16mm strapping, pressing the upper switching plate causes the switching pin to push the switching connecting plate and compress the switching spring. The first bearing wheel group moves laterally inward with the switching axis, while the second bearing wheel group moves automatically outward under the linkage. Only the first bearing wheel group contacts the inner ring of the 16mm strapping roll in the release cavity. At the moment the switching plate is pressed down to the end, the upper locking pin slides into the horizontal section along the inclined section of the locking groove. The locking pin causes the entire switching bracket to move upward, and the lower locking pin disengages from the rectangular section. Under the action of the switching spring, the switching shaft and the second bearing wheel group... The load-bearing wheel assembly instantly resets; the locking post slides into the rectangular section along the horizontal section, and the card holder spring forces the switching card holder to move downward. The rectangular section forms a self-locking mechanism with the locking post, locking the first load-bearing wheel assembly and maintaining its inner load-bearing position. Meanwhile, the second load-bearing wheel assembly moves outward under the reset force of its own switching spring and will not contact the strapping. The switching adjustment mechanism utilizes the reset characteristic of the switching spring and the limiting structure of the locking groove to achieve rapid switching between the first and second load-bearing wheel assemblies, adapting to strapping of different widths without replacing the entire strapping release mechanism. This solves the technical problem of rapid replacement of two different widths of strapping. Attached Figure Description

[0036] To facilitate understanding of the present invention by those skilled in the art, specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood through the specific circumstances.

[0038] like Figure 1As shown, this invention provides a steel coil packing strap release device, including a transfer mechanism and a packing strap release mechanism disposed on the transfer mechanism; the packing strap release mechanism is used to carry and release the packing strap, and the transfer mechanism is used to drive the packing strap release mechanism from the storage area to the packing area; the transfer mechanism includes a track 1 arranged opposite to each other and a transfer motor 2 fixed to the ground via a motor base (one transfer motor 2 is provided on each of the left and right sides); a transfer sprocket 3 is keyed to the motor shaft of the transfer motor 2, and the transfer sprockets 3 on both sides are connected by a transfer chain 4; a transfer seat 5 is in rolling cooperation with the track 1 through track wheels 6, and the transfer chain 4 is fixed to the bottom of the transfer seat 5; the transfer motor 2 drives the transfer seat 5 to move along the track 1 in both forward and reverse rotation; as shown Figure 2 As shown, the strapping release mechanism includes a release base plate 7 and a release box 8 disposed on the release base plate 7; the release box 8 is a rectangular box structure with an opening on the top side, and a strapping discharge port 9 is provided on the right side of the release box 8; a partition 10 is vertically provided inside the release box 8, which divides the interior of the release box 8 into several release chambers 11 (this application takes two partitions 10 and three release chambers 11 as an example); a release wheel 12 is rotatably fitted on the side of the release chamber 11 near the strapping discharge port 9 via a rotating shaft, the release wheel 12 is a cylindrical structure, and the end of the strapping passes around the release wheel 12 and exits from the strapping discharge port 9; Figure 3-5 As shown, each release chamber 11 has a first bearing wheel group 13 and a second bearing wheel group 14 symmetrically arranged on the left and right sides at its bottom. The first bearing wheel group 13 and the second bearing wheel group 14 are used to carry packing straps of different widths (16mm and 19mm in this application, and also 25mm and 32mm, etc.). The release box 8 has a switching horizontal adjustment mechanism on both sides. The output end of the switching horizontal adjustment mechanism is connected to the first bearing wheel group 13 and the second bearing wheel group 14 respectively. The switching horizontal adjustment mechanism drives the first bearing wheel group 13 to move inward, and the second bearing wheel group 14 automatically moves outward. The first bearing wheel group 13 contacts and carries the packing strap of the first width. The switching horizontal adjustment mechanism drives the second bearing wheel group 14 to move inward, and the first bearing wheel group 13 automatically moves outward. The second bearing wheel group 14 contacts and carries the packing strap of the second width.

[0039] like Figure 3-5As shown, the lateral adjustment mechanism includes a switching shaft 15 that slides with the release box 8. One end of the switching shaft 15 is fixed to the first bearing wheel group 13 and the second bearing wheel group 14, respectively. The other end of the switching shaft 15 extends out of the outside of the release box 8 and is fixed to one side of the switching connecting plate 16. The other side of the switching connecting plate 16 is connected to the switching pressure plate 18 via a switching pressure column 17. The upper switching pressure plate 18 is used to control the lateral adjustment of the first bearing wheel group 13, and the lower switching pressure plate 18 is used to control the lateral adjustment of the second bearing wheel group 14. A switching spring 19 passes through the switching shaft 15 between the switching connecting plate 16 and the release box 8. The switching spring 19 is used to force the first bearing wheel group 13 or the second bearing wheel group 14 to move laterally outward. The switching connecting plate 16 and the switching shaft 15 are connected to the release box 8. A spring ring cover 20 is provided on one side of the switching shaft 15, and the spring ring cover 20 surrounds the outside of the switching shaft 15; when the switching pressure plate 18 is pressed, the spring ring cover 20 contacts the side of the release box 8, and the switching spring 19 is accommodated inside the spring ring cover 20; a switching base frame 21 is provided on both sides of the release base plate 7, and a switching bracket 22 is slidably fitted inside the switching base frame 21; the upper side of the switching bracket 22 is connected to one end of the bracket guide post 23, and the other end of the bracket guide post 23 extends upward through the switching base frame 21, and the end of the bracket guide post 23 has an anti-disengagement structure; a bracket spring 24 passes through the bracket guide post 23, and the two ends of the bracket spring 24 are located between the switching base frame 21 and the switching bracket 22, and the bracket spring 24 is used to force the switching bracket 22 to slide downward; Figure 3 As shown, the switching card holder 22 has a locking groove 25 opposite to it, and the switching pressure column 17 has a locking column 26. The locking column 26 is slidably fitted in the locking groove 25. The upper side of the locking groove 25 is provided with an inclined section, a horizontal section and a rectangular section in sequence. The card holder spring 24 forces the upper side of the locking groove 25 to slide in contact with the locking column 26.

[0040] like Figure 5 As shown, when the 16mm strapping needs to be replaced, pressing the upper switching plate 18 causes the switching pin 17 to push the switching connecting plate 16 and compress the switching spring 19. The first bearing wheel assembly 13 moves laterally inward with the switching shaft 15, while the second bearing wheel assembly 14 moves automatically outward under the linkage. Only the first bearing wheel assembly 13 contacts the inner ring of the 16mm strapping roll in the release chamber 11. At the moment the switching plate 18 is pressed down to the end, the upper locking pin 26 slides into the horizontal section along the inclined section of the locking groove 25, and the locking pin... 26 causes the switching bracket 22 to move upward as a whole, and the lower locking post 26 disengages from the rectangular section. Under the action of the switching spring 19, the switching shaft 15 and the second bearing wheel group 14 are instantly reset. The locking post 26 slides into the rectangular section along the horizontal section, and the bracket spring 24 forces the switching bracket 22 to move downward. The rectangular section forms a self-locking mechanism with the locking post 26, and the first bearing wheel group 13 is locked, maintaining the inner bearing position. The second bearing wheel group 14 moves outward under the reset force of its own switching spring 19 and will not contact the packing strap.

[0041] The switching mechanism utilizes the reset characteristic of the switching spring 19 and the limiting structure of the locking groove 25 to achieve rapid switching between the first and second load-bearing wheel sets 14, adapting to different widths of packing straps without replacing the entire packing strap release mechanism; thus solving the technical problem of rapid replacement of two different widths of packing straps.

[0042] like Figure 3 As shown, the first load-bearing wheel set 13 includes a wheel set frame 27 with a U-shaped cross section and a support wheel 28 rotatably fitted on the wheel set frame 27; the support wheel 28 includes a horizontal section located in the middle and snap-fit ​​sections on both sides of the horizontal section. The width of the horizontal section of the support wheel 28 is slightly larger than the first width (16mm) of the packing strap. The horizontal section is used to contact the steel strip surface of the first width (16mm) packing strap, and the snap-fit ​​sections are used to limit the two ends of the first width (16mm) packing strap to prevent the packing strap from tipping over or bumping during release; the second load-bearing wheel set 14 has the same structure as the first load-bearing wheel set 13; a rubber pad is sleeved on the outer side of the support wheel 28.

[0043] like Figure 6 As shown, the side of the transfer mechanism is equipped with a strapping tape storage mechanism and a strapping tape clamping mechanism. There are two strapping tape storage mechanisms, one for storing 16mm wide strapping tape and the other for storing 19mm wide strapping tape. The strapping tape clamping mechanism is used to move the strapping tape from the storage mechanism to the release mechanism. Figure 7 As shown, the packing strap storage mechanism includes a feeding slide shaft 29, a feeding slide plate 30, and a storage box 31; the feeding slide shaft 29 is located on both sides of the pit via a shaft seat 32, and the feeding slide plate 30 is slidably engaged with the feeding slide shaft 29 via a sliding sleeve 33; as shown... Figure 8-9 As shown, a feeding rack 34 is provided on the lower side of the feeding slide plate 30. Feeding motors 35 are fixed to both sides of the pit via motor supports. A feeding gear 36 is keyed to the motor shaft of the feeding motor 35, and the feeding gear 36 meshes with the feeding rack 34. A stepped push plate channel 37 is provided in the middle of the feeding slide plate 30, and a stepped feeding support plate 38 fits into the push plate channel 37. A U-shaped upward moving base 39 is provided on the lower side of the feeding slide plate 30, and an upward moving push rod 4 is provided on the lower side of the upward moving base 39. 0. The push head of the upward push rod 40 passes through the upward base frame 39 and is fixed to the lower side of the feeding tray 38. The storage box 31 is set across the upper side of the feeding slide shaft 29 by the support leg 41. The storage box 31 has a rectangular box structure. The bottom of the storage box 31 is provided with a storage inlet 42 with a circular cross section. The side of the storage box 31 is provided with a storage outlet 43 with a rectangular opening. The storage box 31 is provided with an interval separation component. The interval separation component is used to divide the three packing straps into equal intervals corresponding to the release chamber 11.

[0044] The feeding motor 35 drives the feeding slide plate 30 to move. When the feeding slide plate 30 moves to the outside, it horizontally stacks the packing straps on the feeding pallet 38 through the lifting device. When the feeding slide plate 30 moves to the bottom of the storage box 31 and corresponds to the storage inlet 42, the upward push rod 40 extends and drives the feeding pallet 38 to move upward, so that the horizontally stacked packing straps can enter the storage box 31 through the storage inlet 42. The interval separation component divides the three packing straps on the top side into equal intervals. The packing strap clamping mechanism moves the three equally divided packing straps from the packing strap storage mechanism to the release chamber 11 of the packing strap release mechanism.

[0045] like Figure 10-11 As shown, the interval separation assembly includes an interval fixing shaft 44 and an interval swing block 45 fixed in the inner cavity of the storage box 31, and also includes an interval limiting shaft 46 disposed in the inner cavity of the storage box 31; the interval swing block 45 is rotatably coupled to the interval fixing shaft 44 via a torsion spring (not shown in the figure), and the interval swing block 45 has a triangular cross section; the interval limiting shaft 46 is located outside the interval fixing shaft 44, and the torsion spring is used to force the upper edge of the interval swing block 45 to contact the interval limiting shaft 46, so that the upper side of the interval swing block 45 is in a horizontal state; a lifting cylinder 47 is provided at the top center of the storage box 31, and the push head of the lifting cylinder 47 is downward. The cylinder extends into the storage box 31 and is fixed to the cylinder frame 48. The cylinder frame 48 is equipped with a double-headed cylinder 49 (both sides of the double-headed cylinder 49 move in the same direction, extending to the sides or retracting at the same time). The push head of the double-headed cylinder 49 extends out of the cylinder frame 48 and is fixed to the lifting clamp 50. The lower outer edge of the lifting clamp 50 is equipped with a rubber clamp 51. The outer side of the rubber clamp 51 is an arc-shaped protrusion corresponding to the inner edge of the packing strap. The side of the storage box 31 is equipped with a discharge cylinder 52. The push head of the discharge cylinder 52 extends into the storage box 31 and is fixed to the discharge push block 53. The outer side of the discharge push block 53 has an arc-shaped notch corresponding to the outer edge of the packing strap.

[0046] The spacer separation component is designed to divide the three topmost packing straps into equal intervals; its working process is as follows:

[0047] First, the lifting cylinder 47 at the top of the storage box 31 is activated. The lifting cylinder 47 pushes downward, causing the cylinder frame 48 and the double-headed cylinder 49 inside the frame to move downward simultaneously until the rubber clamping block 51 on the lower side of the lifting clamping plate 50 corresponds to the inner edge of the uppermost packing strap. Then, the double-headed cylinder 49 actuates, and the pusher extends outward simultaneously, causing the lifting clamping plate 50 to move towards the inner edge of the packing strap to clamp the uppermost packing strap. Next, the pusher of the lifting cylinder 47 retracts upward, causing the clamped packing strap to be lifted upward. The upward push rod 40 extends, causing the feeding tray 38 to move upward, so that the uppermost packing strap moves to the corresponding position. The outer edge of the clamped packing strap contacts the side of the spacer swing block 45. The spacer swing blocks 45 on both sides rotate, and the packing strap passes through the two lower sides. The interval swing block 45 is driven back to its original position by the torsion spring; then, the lifting cylinder 47 drives the lifting clamping plate 50 to pass through the inner edge of the packing strap and clamp the second packing strap; the first packing strap is clamped on the uppermost interval swing block 45, the second packing strap is clamped on the middle interval swing block 45, and the third packing strap is clamped on the lowermost interval swing block 45; so that the three packing straps are spaced apart; when the packing straps are transferred from the storage box 31 to the packing strap release mechanism, the discharge cylinder 52 on the side of the storage box 31 is activated, which drives the discharge push block 53 to move. The arc-shaped notch on the outer side of the discharge push block 53 is adapted to the outer edge of the packing strap, pushing the three packing straps to the preset material picking position of the storage box 31 so that the packing strap clamping mechanism can subsequently grab and transfer them.

[0048] The strapping clamping mechanism is used to clamp and transfer three spaced-apart straps, such as... Figure 12 As shown, the packing strap clamping mechanism includes a robotic arm 54 mounted on the ground and a clamping base 55 mounted on the execution end of the robotic arm 54. The clamping base 55 has vertically mounted clamping slide shafts 56, arranged in pairs, one set on each side. T-shaped clamping slide plates 57 are slidably engaged with the clamping slide shafts 56 on both sides (three on one side of each clamping slide plate 57, for a total of six). The upper ends of the three clamping slide plates 57 on the left side are equipped with clamping pads 58, and the lower ends of the three clamping slide plates 57 on the right side are equipped with clamping pads 58. Two clamping motors 59 are mounted on the upper side of the clamping base 55. The motor shafts of the clamping motors 59 are fixed to one side of the clamping screw 60 via a coupling, and the other side of the clamping screw 60 is rotatably engaged with the lower side of the clamping base 55. The left clamping screw 60 is threadedly engaged with the three left clamping slide plates 57, and the right clamping screw 60 is threadedly engaged with the three right clamping slide plates 57.

[0049] The arc-shaped notch on the outer side of the discharge pusher 53 matches the outer edge of the strapping, pushing the three strappings to the preset retrieval position in the storage box 31. The robotic arm 54 drives the clamping base 55 and the clamping slide plate 57 to move, so that the three clamping slide plates 57 on the left are located below the three strappings, and the three clamping slide plates 57 on the right are located above the three strappings. Subsequently, the two clamping motors 59 on the upper side of the clamping base 55 start synchronously, and the three clamping slide plates 57 on the left slide vertically upward along the clamping slide shaft 56; the three clamping slide plates 57 on the right slide vertically upward along the clamping slide shaft 56. The clamping slide 56 slides vertically downwards; the left clamping slide 57 and the right clamping slide 57 move closer to each other, and the clamping pads 58 simultaneously contact and apply clamping force from the upper and lower sides of the strapping until the three strappings are clamped; after clamping is completed, the robotic arm 54 adjusts its posture again, driving the clamping base 55 and the clamped strappings to move directly above the strapping release mechanism, so that each strapping corresponds to one of the three release chambers 11 of the release mechanism; then the clamping motor 59 rotates in the opposite direction to place the strappings into the release chambers 11.

[0050] The strapping is stacked on the feeding pallet 38, and dust accumulates on the outer side of the strapping; to solve this problem, such as Figure 13 As shown, a covering component is provided on the lower side of the storage box 31. The covering component is used to cover the packing straps stacked on the loading pallet 38. The covering component includes a covering drive motor 61 and a corrugated protective cover 62 located on both sides. The covering drive motor 61 on one side is fixed to the ground by an L-shaped mounting plate 63, and the covering drive motor 61 on the other side is fixed to the lower side of the storage box 31 by an L-shaped mounting plate 63.

The sliding shaft 66 slides up and down; the upper side of the corrugated protective cover 62 is fixed to the storage inlet 42 on the lower side of the storage box 31, and the lower side of the corrugated protective cover 62 is fixed to the covering drive slide plate 67; the packing straps are horizontally stacked on the feeding pallet 38 by the lifting device; when the feeding slide plate 30 moves to the bottom of the storage box 31 and corresponds to the storage inlet 42, the covering drive motor 61 starts, driving the covering drive slide plate 67 to move downward, so that the corrugated protective cover 62 covers the stacked packing straps. The vertical extension and retraction of the corrugated protective cover 62 is realized by the synchronous chain 65, the slide plate, and the sliding shaft mechanism. It only opens at the moment of feeding, and forms a continuous sealed cavity at other times to block the dust environment from contaminating the packing straps; at the same time, the corrugated protective cover 62 is coaxial with the storage inlet 42 and does not contact the outer edge of the strip roll during covering, so as to avoid scratching the surface of the steel strip.

[0051] Considering the dust prevention issue of the three packing straps inside storage box 31, such as Figure 7 , Figure 14 As shown, the storage outlet 43 on the side of the storage tank 31 is provided with four isolation mounting cavities 68, through which the packing strap can pass; the isolation mounting cavities 68 are provided with slag removal brushes 69 (the two middle ones are provided on both the upper and lower sides, the upper one on the lower surface of the upper isolation mounting cavity 68, and the lower one on the upper surface of the lower isolation mounting cavity 68); as Figure 15-16 As shown, a mating opening 70 is provided on the side of the isolation mounting cavity 68 corresponding to the slag removal brush 69, and a switching spray chamber 71 is slidably fitted inside the mating opening 70; a switching motor 72 is provided on the side of the isolation mounting cavity 68, and the motor shaft of the switching motor 72 extends into the isolation mounting cavity 68 and is keyed to the switching gear 73; a switching rack 74 is provided on the side of the switching spray chamber 71, and the switching gear 73 meshes with the switching rack 74; the switching motor 72 rotates forward and backward, thereby driving the switching spray chamber 71 to slide along the mating opening 70; as Figure 17-18 As shown, the isolation installation cavity 68 has a horizontally arranged rectangular cavity structure air guide plate 75. The side of the air guide plate 75 is connected to an external nitrogen source (the nitrogen source can be a high-pressure gas source within the plant area) via a flexible hose. Several air guide columns 76 are provided on the air guide plate 75, and the air guide columns 76 are connected to the inner cavity of the air guide plate 75. An air guide port 77 is provided on the upper side of each air guide column 76. The switching spray cavity 71 has a rectangular cavity structure, and a partition plate 78 is provided inside the switching spray cavity 71. The switching jet chamber 71 is internally divided into upper and lower parts; the lower side of the switching jet chamber 71 and the partition plate 78 are both slidably fitted onto the air guide column 76 (the sliding fit between the two and the air guide column 76 is sealed by an annular rubber plug); an air curtain opening 79 is provided on the upper side of the switching jet chamber 71, and the air curtain opening 79 communicates with the upper chamber of the switching jet chamber 71; a slag removal opening 80 is provided on the side of the switching jet chamber 71, and the slag removal opening 80 communicates with the lower chamber of the switching jet chamber 71; Figure 18-19 As shown, when the packing straps are inside the storage box 31, nitrogen gas is sprayed into the upper chamber of the switching spray chamber 71 through the air guide column 76, and the nitrogen gas is sprayed out from the air curtain port 79; a continuous nitrogen air curtain is formed at the storage discharge port 43 to prevent the outside salt spray air and dust from entering the box, thus achieving "air curtain sealing"; the discharge push block 53 pushes the three packing straps to the preset material picking position of the storage box 31, the packing strap clamping mechanism transfers the three packing straps, and the slag removal brush 69 brushes away the impurities on the upper and lower sides of the three packing straps; then the switching motor 72 starts, thereby driving the switching spray chamber 71 to slide upward along the mating port 70, the air guide port 77 is connected to the lower chamber of the switching spray chamber 71, and nitrogen gas is sprayed out from the slag removal port 80 to clean the slag removal brush 69; then the switching motor 72 reverses, the switching spray chamber 71 resets, and the system returns to the air curtain dust prevention state.
