Description

Technical Field

[0001] The present invention relates to the technical field of sanding machines, and specifically to a new type of environmentally friendly sanding machine for processing special-shaped curved surfaces. Background Art

[0002] A sanding machine, also known as a grinding machine, is one of the commonly used equipment in modern sheet processing industry. It uses abrasive belts, sandpapers or grinding wheels and other abrasives to replace tools for processing workpieces. The purpose is to remove the surface materials, burrs, milling and other processing marks of the workpieces, so that the workpieces meet certain thickness dimensions or surface quality requirements; it uses cutting tools equipped with abrasives to sand the workpieces to improve their thickness accuracy, flatness and roughness quality, and provides a good base surface for the surface decoration, painting of wooden parts or secondary processing of sheets.

[0003] In the prior art, when the sanding machine grinds different materials of sheets, different types of sanding machines are usually used separately. Frequent replacement of sanding machines will increase the cost of the equipment. And when the sanding machine processes the sheets, debris is generated when the surface of the sheets is ground by the grinding wheel or abrasive belt. The debris will be thrown out under the action of the grinding wheel or abrasive belt to generate a large amount of debris dust. These dusts float in the air. If the staff is in this environment for a long time, it will cause certain damage to their physical health. Summary of the Invention

[0004] The purpose of the present invention is to provide a new type of environmentally friendly sanding machine for processing special-shaped curved surfaces, so as to solve the problems raised in the above background art.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A new type of environmentally friendly sanding machine for processing special-shaped curved surfaces, including: a bracket, a conveyor belt is arranged on the bracket, and the transmission shaft in the conveyor belt is connected to a motor; on the side of the conveyor belt away from the bracket, there is a housing cover, and a material port is arranged on the side wall of the housing cover; a sanding assembly is arranged inside the housing cover, and the sanding assembly is used for grinding the surface of the sheet.

[0007] The sanding assembly includes: a surface sanding mechanism, which is located inside the housing cover; the surface sanding mechanism is used for grinding the surface of the sheet; side sanding mechanisms are arranged on both sides of the conveyor belt; the side sanding mechanisms are used for grinding the sides of the sheet; a dust removal assembly is arranged inside the housing cover, and the dust removal assembly is used for collecting and cleaning the debris generated by the grinding process.

[0008] The staff places the curved panel on the surface of the conveyor belt, and then starts the motor in the conveyor belt. The drive shaft of the motor drives the drive shaft in the conveyor belt, and the drive shaft drives the conveyor belt to rotate. During the rotation of the conveyor belt, the curved panel is driven to move towards the side close to the outer housing. When the curved panel enters the outer housing under the action of the conveyor belt, then, the staff controls the start of the surface sanding mechanism through the controller, and the surface sanding mechanism immediately grinds the surface of the curved panel, and the surface sanding mechanism polishes the surface of the curved panel flat; Subsequently, the curved panel moves under the action of the conveyor belt, and the curved panel moves towards the side sanding mechanism. The staff controls the start of the side sanding mechanism through the controller, and the side sanding mechanism immediately grinds the side of the curved panel, and the side sanding mechanism polishes the side of the curved panel flat. When the sanding assembly grinds the curved panel, the dust removal assembly collects most of the debris generated by the grinding process, preventing the debris from entering the air with the conveyor belt, increasing the dust concentration in the air, and damaging the health of the staff, thereby ensuring the life and health of the staff.

[0009] Preferably, the surface sanding mechanism includes: a processing chamber, the processing chamber is located inside the outer housing, and the processing chamber is fixedly connected to the outer housing; a transmission box is arranged inside the processing chamber, a rotating shaft is arranged on the side wall of the transmission box, and the rotating shaft passes through the processing chamber and is connected to a rotating motor; an extension plate is arranged on the outer wall of the processing chamber, and a rotating motor is arranged on the extension plate; a number of transmission holes are symmetrically formed on the surface of the transmission box, a sanding shaft is arranged in the transmission hole, and the sanding shaft is rotatably connected to the transmission hole; a transmission gear is installed on the shaft wall of the sanding shaft, and the transmission gears on multiple sanding shafts are meshed and driven, and one of the transmission gears is meshed with a main gear, and the main gear is connected to a drive motor; the drive motor is arranged in the transmission box; a first sanding wheel is arranged on the side of the sanding shaft away from the transmission box.

[0010] Preferably, abrasive strips are arranged on the surface of the first sanding wheel; a second sanding wheel is arranged at one end of the sanding shaft away from the first sanding wheel; grinding paper is adhered to the surface of the second sanding wheel;

[0011] When the plate to be polished is a wooden plate, the curved panel moves into the processing chamber under the action of the conveyor belt. Then, the staff controls the start of the drive motor in the transmission box through the controller. The drive shaft in the drive motor drives the main gear to rotate. During the rotation of the main gear, the main gear meshes with the transmission gear, and the transmission gear rotates under the action of the main gear. During the rotation of the transmission gear, the sanding shaft is driven to rotate. The sanding shaft rotates in the transmission hole. During the rotation of the sanding shaft, the first sanding wheel is driven to rotate, and the first sanding wheel immediately grinds the surface of the curved panel. When the abrasive strips arranged on the surface of the first sanding wheel polish the curved panel flat, it plays a certain role in protecting the curved panel and preventing damage to the surface of the curved panel during the grinding process;

[0012] When the plate to be polished is a metal plate, the staff controls the rotation motor in the processing chamber to start through the controller. The drive shaft in the rotation motor drives the rotation shaft to rotate. Under the driving action of the rotation motor, the rotation shaft drives the transmission box to rotate. During the rotation of the transmission box, the first sanding wheel is driven to rotate. The first sanding wheel rotates 180°, and rotates to the side of the transmission box away from the conveyor belt; while the second sanding wheel rotates to the side of the transmission box close to the conveyor belt. Subsequently, the metal plate moves to the bottom of the processing chamber under the action of the conveyor belt. Subsequently, the second sanding wheel rotates under the driving action of the driving motor, and the second sanding wheel immediately grinds the metal plate; realizing the integrated sanding of wooden plates and metal plates, so that the plates and metal plates do not need to be ground by different sanding equipment, reducing the cost of the equipment.

[0013] Preferably, the side sanding mechanism includes: a rotation cavity symmetrically opened on the surface of the bracket; a rotation shaft is arranged inside the rotation cavity; a third sanding wheel is arranged on the shaft wall of the rotation shaft; a pulley is arranged on the side of the rotation shaft away from the third sanding wheel, and the two pulleys are connected by a transmission belt; a motor is arranged at one end of one of the pulleys away from the rotation shaft.

[0014] When the surface of the curved plate is ground and flattened under the action of the surface sanding mechanism, the conveyor belt drives the curved plate to move towards the side close to the side sanding mechanism. The staff controls the motor in the rotation cavity to start through the controller. The motor drive shaft drives the pulley to rotate. During the rotation of the pulley, the transmission belt is driven to drive, and the transmission belt drives the other pulley to rotate. During the rotation of the pulley, the rotation shaft is driven to rotate, and the rotation shaft drives the third sanding wheel to rotate, and the third sanding wheel immediately grinds the side of the curved plate, making the side of the curved plate ground and flattened.

[0015] Preferably, the dust removal component includes: a placement cavity opened in the inner wall of the processing chamber; a fan is symmetrically arranged in the placement cavity, and a pipeline is arranged inside the outer shell cover; the pipeline communicates with the outside air; the fan communicates with the pipeline; an air duct is arranged on the side of the fan away from the placement cavity; an air suction port is opened on the side wall of the processing chamber adjacent to the air duct; a collection box is arranged on the side of the conveyor belt close to the bracket, the collection box communicates with the air suction port, and a suction fan and a filter screen are arranged in the collection box.

[0016] Before the sanding assembly grinds the curved panel, the worker controls the blower in the placement cavity to start through the controller. The blower inhales outside air through the pipeline. After pressurizing the inhaled air, the blower blows the air out from the air duct. The high-pressure gas passes through the air duct, and a wind wall is formed between the conveyor belt and the processing chamber. The wind wall isolates the inside and outside of the processing chamber, making it difficult for the debris generated by the grinding process in the processing chamber to escape from the processing chamber. The worker controls the exhaust fan inside the collection box to start through the controller. The exhaust fan inhales the air in the processing chamber into the collection box through the air suction port. During the inhalation of the air inside the processing chamber, the air mixed with debris moves and is inhaled into the air suction port. The filter screen in the collection box filters and collects the debris; further preventing the debris from entering the air and increasing the dust concentration in the air, thereby affecting the life and health of the workers.

[0017] Preferably, an airbag is arranged between the two blowers. The air inlet pipe in the airbag passes through the outer wall of the processing chamber, and the air outlet pipe in the airbag passes through the inner wall of the processing chamber; one-way valves are arranged in the air inlet pipe and the air outlet pipe; a push plate is arranged on the side of the airbag away from the placement cavity, and a push rod is arranged on the side of the push plate away from the airbag. The push rod passes through the inner wall of the processing chamber; the push rod is slidably connected to the inner wall of the processing chamber; a top plate is arranged on the side of the push rod away from the push plate;

[0018] When the surface sanding mechanism grinds the surface of the curved panel, due to the certain curvature undulation on the surface of the processed panel, when the first sanding wheel grinds the convex part of the undulating surface, the convex part on the surface of the curved panel squeezes the first sanding wheel upward. The first sanding wheel squeezes the sanding shaft upward. During the squeezing process of the sanding shaft, it drives the second sanding wheel to squeeze upward. The second sanding wheel squeezes the top plate upward. The top plate is pushed by the squeezing force to drive the push rod. The push rod pushes the push plate upward. The push plate is pushed by the push rod and squeezes the airbag upward. The airbag is squeezed and deformed. At this time, the air pressure inside the airbag is greater than the air pressure inside the processing chamber. The gas in the airbag immediately sprays outwards through the one-way valve in the air outlet pipe. The sprayed gas cleans the surface of the second sanding wheel and blows off the residual debris on the surface of the second sanding wheel. During the spraying process of the gas, the gas sprays towards the side close to the conveyor belt, blowing the debris and dust in the processing chamber towards the side close to the air suction port; when the first sanding wheel slides down from the convex part of the curved panel surface, the airbag immediately loses the squeezing force of the push plate. At this time, the air pressure inside the airbag is less than the outside air pressure, and the outside air immediately enters the airbag through the one-way valve in the air inlet pipe, making the airbag return to its original state.

[0019] Preferably, L-shaped plates are arranged at the bottoms of the first sanding wheel and the second sanding wheel; a fixing cavity is formed at the end of the sanding shaft, a fixing plate is arranged in the fixing cavity, and the fixing plate is connected to the fixing cavity through a spring; an L-shaped groove is arranged in the fixing cavity;

[0020] When the surface of the first sanding wheel or the second sanding wheel is worn and needs to be replaced, the staff squeezes the first sanding wheel to the side away from the fixed cavity. During the squeezing process, the first sanding wheel is rotated counterclockwise by 45°, so that the L-shaped plate at the bottom of the first sanding wheel disengages from the L-shaped groove; the L-shaped plate rotates into the fixed cavity; subsequently, under the action of the spring, the fixing plate pushes the first sanding wheel to the side away from the fixed cavity, so that the first sanding wheel disengages from the fixed cavity, and further the first sanding wheel is separated from the sanding shaft;

[0021] The staff takes out a brand-new first sanding wheel, aligns the L-shaped plate at the bottom of the first sanding wheel with the fixed cavity, and presses the L-shaped plate into the fixed cavity. During the process of pressing the L-shaped plate into the fixed cavity, the L-shaped plate squeezes the fixing plate downward, and the fixing plate squeezes the spring downward. The spring is squeezed and deformed. During the process of the staff pressing the first sanding wheel downward, it drives the first sanding wheel to rotate clockwise by 45°, so that the L-shaped plate rotates from the fixed cavity to the L-shaped groove. Subsequently, the first sanding wheel is released, and the fixing plate immediately moves under the action of the spring. The fixing plate moves to the side close to the fixed cavity, and the fixing plate locks and fixes the L-shaped plate in the L-shaped groove, realizing the rapid replacement of the first sanding wheel or the second sanding wheel, shortening the equipment maintenance time, and thus improving the grinding efficiency of the equipment.

[0022] Preferably, a clamping plate is arranged at the bottom of the material inlet, and the clamping plate is connected with the material inlet through a spring; a plurality of balls are arranged on the side of the clamping plate close to the conveyor belt; an arc-shaped edge is arranged on the side of the clamping plate close to the feeding direction;

[0023] The staff places the curved panel on the surface of the conveyor belt, and then starts the conveyor belt. Under the action of the motor, the conveyor belt drives the curved panel to move towards the processing chamber. When the curved panel enters the inside of the outer shell cover, the curved panel passes through the material inlet. During the process of moving forward, the curved panel enters from the side of the arc-shaped edge of the clamping plate, so that the surface of the curved panel contacts the bottom surface of the clamping plate. The clamping plate receives the upward supporting force from the curved panel, and the clamping plate squeezes the spring upward. The spring is squeezed and deformed and reacts on the clamping plate. The clamping plate immediately squeezes the curved panel, so that the curved panel is not easily displaced. When the curved panel moves under the action of the conveyor belt, the balls at the bottom of the clamping plate rotate with the movement of the curved panel, so that the curved panel can slide conveniently on the bottom surface of the clamping plate.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0025] 1. When the sanding assembly grinds the curved panel, the dust removal assembly collects most of the debris generated by the grinding process, preventing the debris from entering the air with the conveyor belt, increasing the dust concentration in the air, and damaging the health of the staff. Thus, the life and health of the staff are protected.

[0026] 2. When the plate to be polished is metal, the staff controls the motor in the processing chamber to start through the controller. The drive shaft of the motor drives the rotating shaft to rotate. Under the driving action of the motor, the rotating shaft drives the transmission box to rotate. During the rotation of the transmission box, the first sanding wheel is driven to rotate. The first sanding wheel rotates 180°, and rotates to the side of the transmission box away from the conveyor belt; while the second sanding wheel rotates to the side of the transmission box close to the conveyor belt. Subsequently, the metal plate moves to the bottom of the processing chamber under the action of the conveyor belt. Then, the second sanding wheel rotates under the driving action of the motor, and the second sanding wheel immediately grinds the metal plate; realizing the integrated sanding of wooden plates and metal plates, so that the plates and metal plates do not need to be ground by different sanding equipment, reducing the cost of the equipment.

[0027] 3. Align the L-shaped plate at the bottom of the first sanding wheel with the fixed cavity, and press the L-shaped plate into the fixed cavity. During the process of pressing the L-shaped plate into the fixed cavity, the L-shaped plate squeezes the fixed plate downward, and the fixed plate squeezes the spring downward. The spring is squeezed and deformed. When the staff presses the first sanding wheel downward, it drives the first sanding wheel to rotate clockwise by 45°, so that the L-shaped plate rotates from the fixed cavity to the L-shaped groove. Subsequently, release the first sanding wheel, and the fixed plate immediately moves under the action of the spring. The fixed plate moves to the side close to the fixed cavity, and the fixed plate locks and fixes the L-shaped plate in the L-shaped groove, realizing the rapid replacement of the first sanding wheel or the second sanding wheel, shortening the equipment maintenance time, and thus improving the grinding efficiency of the equipment.

The high-pressure gas forms a wind wall between the conveyor belt 11 and the processing chamber 31, and the wind wall isolates the inside and outside of the processing chamber 31, so that the debris generated by the grinding process in the processing chamber 31 is not easy to run out of the processing chamber 31; the staff controls the suction fan inside the collection box 55 to start through the controller. The suction fan sucks the air in the processing chamber 31 into the collection box 55 through the air suction port 54. During the inhalation of the air inside the processing chamber 31, the air mixed with the debris moves and is inhaled into the air suction port 54, and the filter screen in the collection box 55 filters and collects the debris.

[0060] As a specific embodiment of the present invention, an airbag 56 is arranged between the two fans 52. The intake pipe in the airbag 56 passes through the outer wall of the processing chamber 31, and the exhaust pipe in the airbag 56 passes through the inner wall of the processing chamber 31; one-way valves are arranged in the intake pipe and the exhaust pipe; a push plate 57 is arranged on the side of the airbag 56 away from the placement cavity 51, and a push rod 58 is arranged on the side of the push plate 57 away from the airbag 56. The push rod 58 passes through the inner wall of the processing chamber 31; the push rod 58 is slidably connected to the inner wall of the processing chamber 31; a top plate 59 is arranged on the side of the push rod 58 away from the push plate 57;

[0061] When the surface sanding mechanism 3 grinds the surface of the curved panel, due to the certain curvature undulation on the surface of the processed panel, when the first sanding wheel 37 grinds the convex part of the undulating surface, the convex part on the surface of the curved panel presses the first sanding wheel 37 upward. The first sanding wheel 37 presses the sanding shaft 34 upward. During the pressing process of the sanding shaft 34, it drives the second sanding wheel 38 to press upward. The second sanding wheel 38 presses the top plate 59 upward. Under the pressing action, the top plate 59 pushes the push rod 58, and the push rod 58 pushes the push plate 57 upward. The push plate 57 is pushed by the push rod 58 and presses the airbag 56 upward. The airbag 56 is compressed and deformed under the pressing action. At this time, the air pressure inside the airbag 56 is greater than the air pressure inside the processing chamber 31, and the gas in the airbag 56 then sprays outwards from the one-way valve in the exhaust pipe. The sprayed gas cleans the surface of the second sanding wheel 38 and blows off the debris remaining on the surface of the second sanding wheel 38. During the process of the gas spraying out, the gas sprays towards the side close to the conveyor belt 11, and blows the debris and dust in the processing chamber 31 towards the side close to the air suction port 54; when the first sanding wheel 37 slides down from the convex part of the surface of the curved panel, the airbag 56 immediately loses the pressing action. At this time, the air pressure inside the airbag 56 is less than the external air pressure, and the external air then enters the airbag 56 through the one-way valve in the intake pipe to make the airbag 56 return to its original state.

[0062] The working principle of the present invention:

[0063] The staff places the curved panel on the surface of the conveyor belt 11, and then starts the motor in the conveyor belt 11. The motor drive shaft drives the drive shaft in the conveyor belt 11, and the drive shaft drives the conveyor belt 11 to rotate. During the rotation of the conveyor belt 11, it drives the curved panel to move towards the side close to the outer housing 12. When the curved panel enters the outer housing 12 under the action of the conveyor belt 11, then the staff controls the start of the surface sanding mechanism 3 through the controller, and the surface sanding mechanism 3 immediately grinds the surface of the curved panel, and the surface sanding mechanism 3 polishes the surface of the curved panel flat; then, the curved panel moves under the action of the conveyor belt 11, and the curved panel moves towards the side sanding mechanism 4. The staff controls the start of the side sanding mechanism 4 through the controller, and the side sanding mechanism 4 immediately grinds the side of the curved panel, and the side sanding mechanism 4 polishes the side of the curved panel flat. When the sanding assembly 2 grinds the curved panel, the dust removal assembly 5 collects most of the debris generated by the grinding process to prevent the debris from entering the air with the conveyor belt 11 and increasing the dust concentration in the air;

[0064] The staff places the curved panel on the surface of the conveyor belt 11, and then starts the conveyor belt 11. Under the action of the motor, the conveyor belt 11 drives the curved panel to move towards the processing chamber 31. When the curved panel enters the interior of the outer housing 12, the curved panel passes through the material opening 13. During the movement of the curved panel, it enters from the side of the arc edge of the clamping plate 14, so that the surface of the curved panel contacts the bottom surface of the clamping plate 14. The clamping plate 14 receives the upward supporting force from the curved panel, and the clamping plate 14 squeezes the spring upward. The spring is squeezed and deformed, and reacts with the clamping plate 14. The clamping plate 14 immediately squeezes the curved panel, making it difficult for the curved panel to shift in position. When the curved panel moves under the action of the conveyor belt 11, the balls at the bottom of the clamping plate 14 rotate with the movement of the curved panel, enabling the curved panel to slide conveniently on the bottom surface of the clamping plate 14;

[0065] The curved panel moves into the processing chamber 31 under the action of the conveyor belt 11. Then, the staff controls the start of the motor in the transmission box 32 through the controller. The motor drive shaft drives the main gear 36 to rotate. During the rotation of the main gear 36, the main gear 36 meshes with the transmission gear 35. The transmission gear 35 rotates under the action of the main gear 36. During the rotation of the transmission gear 35, it drives the sanding shaft 34 to rotate. The sanding shaft 34 rotates in the transmission hole 33. During the rotation of the sanding shaft 34, it drives the first sanding wheel 37 to rotate. The first sanding wheel 37 immediately grinds the surface of the curved panel. When the abrasive strips provided on the surface of the first sanding wheel 37 polish the curved panel flat, it plays a certain role in protecting the curved panel to prevent damage to the surface of the curved panel during the grinding process;

[0066] When the plate to be polished is made of metal, the staff controls the motor in the processing chamber 31 to start through the controller. The motor drive shaft drives the rotating shaft to rotate. Under the driving action of the motor, the rotating shaft drives the transmission box 32 to rotate. During the rotation of the transmission box 32, the first sanding wheel 37 is driven to rotate. The first sanding wheel 37 rotates 180°, and rotates to the side of the transmission box 32 away from the conveyor belt 11; while the second sanding wheel 38 rotates to the side of the transmission box 32 close to the conveyor belt 11. Subsequently, the metal plate moves to the bottom of the processing chamber 31 under the action of the conveyor belt 11. Subsequently, the second sanding wheel 38 rotates under the driving action of the motor, and the second sanding wheel 38 immediately grinds the metal plate; realizing the integrated sanding of wooden plates and metal plates.

[0067] When the surface of the curved plate is ground and flattened under the action of the surface sanding mechanism 3, the conveyor belt 11 drives the curved plate to move towards the side close to the side sanding mechanism 4. The staff controls the motor in the rotating cavity 41 to start through the controller. The motor drive shaft drives the pulley 44 to rotate. During the rotation of the pulley 44, the transmission belt is driven to drive, and the transmission belt drives the pulley 44 on the other side to rotate. During the rotation of the pulley 44, the rotating shaft 42 is driven to rotate, and the rotating shaft 42 drives the third sanding wheel 43 to rotate. The third sanding wheel 43 immediately grinds the side of the curved plate, making the side of the curved plate ground and flattened.

[0068] Before the sanding assembly 2 grinds the curved plate, the staff controls the fan 52 in the placement cavity 51 to start through the controller. The fan 52 inhales the outside air through the pipeline. After the fan 52 pressurizes the inhaled air, it blows out from the air duct 53. The high-pressure gas passes through the air duct 53, and the high-pressure gas forms a wind wall between the conveyor belt 11 and the processing chamber 31. The wind wall isolates the inside and outside of the processing chamber 31, making the debris generated by the grinding process in the processing chamber 31 not easy to run out of the processing chamber 31; the staff controls the exhaust fan inside the collection box 55 to start through the controller. The exhaust fan inhales the air in the processing chamber 31 through the air suction port 54 into the collection box 55. During the inhalation of the air inside the processing chamber 31, the air mixed with the debris moves and is inhaled into the air suction port 54. The filter screen in the collection box 55 filters and collects the debris; further avoiding the debris from entering the air and increasing the dust concentration in the air, which will affect the life and health of the staff.

[0069] When the surface sanding mechanism 3 grinds the surface of the curved panel, due to the certain curvature undulation on the surface of the processed panel, when the first sanding wheel 37 grinds the convex part of the undulating surface, the convex part on the surface of the curved panel presses the first sanding wheel 37 upward, and the first sanding wheel 37 presses the sanding shaft 34 upward. During the pressing process of the sanding shaft 34, it drives the second sanding wheel 38 to press upward, and the second sanding wheel 38 presses the top plate 59 upward. Under the extrusion effect, the top plate 59 pushes the push rod 58, and the push rod 58 pushes the push plate 57 upward. Under the pushing action of the push rod 58, the push plate 57 presses the airbag 56 upward. The airbag 56 shrinks and deforms under the extrusion effect. At this time, the air pressure inside the airbag 56 is greater than the air pressure inside the processing chamber 31, and the gas in the airbag 56 then sprays outwards through the one-way valve in the air outlet pipe. The sprayed gas cleans the surface of the second sanding wheel 38 and blows off the debris remaining on the surface of the second sanding wheel 38. During the process of the gas spraying out, the gas sprays towards the side close to the conveyor belt 11, and blows the debris and dust in the processing chamber 31 towards the side close to the air suction port 54; when the first sanding wheel 37 slides down from the convex part on the surface of the curved panel, the airbag 56 immediately loses the extrusion effect. At this time, the air pressure inside the airbag 56 is less than the external air pressure, and the external air then enters the airbag 56 through the one-way valve in the air inlet pipe, causing the airbag 56 to return to its original state.
