Description

Technical Field

[0001] This invention relates to the field of drying technology, specifically to a surface coating drying device for aluminum foil production. Background Technology

[0002] Metal-cased lithium-ion batteries are prone to releasing gas during use, and the increased pressure can lead to explosions. With the continuous advancement of scientific research, a flexible packaging material containing aluminum foil and an aluminum-plastic composite film for lithium batteries has been introduced, which effectively releases battery pressure and reduces the risk of battery explosion.

[0003] Patent publication number CN114992994B discloses a surface coating drying device for aluminum foil production, including a drying chamber. Multiple sets of symmetrically arranged support plates are fixedly connected to both sides of the inner wall of the drying chamber. Adjusting rods are slidably connected to both sides of the inner wall of the drying chamber, and multiple sets of pressure plates are fixedly connected to the outer walls of the adjusting rods. Multiple lead screws are rotatably connected to the inner wall of the drying chamber, and the lead screws are driven by a motor. A locking assembly is provided on the adjusting rod. A moving plate is threaded onto the lead screw, and an air storage cylinder is connected to the moving plate. A nozzle is provided on the air storage cylinder and communicates with it. The moving frame drives the nozzle on the air storage cylinder to reciprocate, drying and blowing away moisture from the aluminum foil, reducing moisture residue on the aluminum foil, improving drying uniformity, and simultaneously drying the aluminum foil on both the top and bottom sides through the nozzles, reducing the problem of slow drying speed on the back of the aluminum foil and improving drying efficiency.

[0004] However, the device still has shortcomings: the device can dry the moisture on the surface of aluminum foil evenly, but the aluminum foil is in a relatively static state during the drying process. It relies solely on the air drying equipment to heat and dry the aluminum foil. Therefore, when there is a lot of residual moisture on the surface of the aluminum foil, the drying time of the aluminum foil is extended accordingly. When the aluminum foil is heated and dried for a long time, it is easy to increase the internal stress, thereby increasing the risk of the aluminum foil surface cracking. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a surface coating drying device for aluminum foil production, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surface coating drying device for aluminum foil production, comprising a main body, an observation window on the front of the main body, a motor on the left side of the main body, a rotating rod rotatably mounted on the inner wall of the main body, the left end of the rotating rod penetrating and fixedly mounted on the right side of the motor output end, and a reciprocating spiral groove formed on the left side of the outer wall of the rotating rod; a plurality of grooving frames are equidistantly and fixedly mounted on the outer wall of the rotating rod, each of the grooving frames having a limit groove on the inner wall of the side of the grooving frame closest to the rotating rod, and a limit block slidably mounted on the outer wall of the grooving frame away from the rotating rod. The limiting block is slidably connected to the outer wall of the slotted frame via a slot. A sliding ring is sleeved and slidably installed on the outer wall of the reciprocating spiral groove of the rotating rod. A hot air blower is fixedly installed through the outer wall of the sliding ring. Two contact plates are fixedly installed on the outer wall of the hot air blower, symmetrically distributed around the axis of the hot air blower. A limiting rod is slidably installed through the interior of each contact plate. The left end of the limiting rod is fixedly installed on the left side of the inner wall of the device body. A heat-gathering cover is fixedly installed on the right side of the contact plate. The slotted frame is located inside the heat-gathering cover. Two arc-shaped plates are slidably installed on the left side of the inner wall of the device body, near the rotating rod. Several U-shaped arc plates are equidistantly and fixedly installed on one side of the outer wall of the rod. Open the observation window on the front of the main body of the device, move the limiting block away from the center of the slot frame, and insert the aluminum foil through the slot on the outer wall of the slot frame until the aluminum foil enters the limiting groove. Then, the operator resets the limiting block to block the slot on the outer wall of the slot frame. Rotate the slot frame and repeat the above steps. Afterward, close the observation window and start the motor. The motor output drives the rotating rod to rotate, which in turn drives the slot frame and the limiting block to rotate. The slot frame then drives the aluminum foil to rotate. As the rotating rod rotates, its reciprocating spiral groove engages with the internal locking block of the sliding ring. The restriction causes the sliding ring to slide left and right along the outer wall of its reciprocating spiral groove when the rotating rod rotates. The sliding ring drives the hot air blower to move synchronously. At this time, the hot air blower performs regular reciprocating sliding air blowing and drying treatment on the aluminum foil inside the slotting frame. When the hot air blower moves left and right, it drives the contact plate to slide along the outer wall of the limiting rod. The contact plate drives the heat-gathering cover to move towards the slotting frame and cover the slotting frame. At the same time, the arc surface of the contact plate will contact the arc surface of the outer wall of the U-shaped arc plate to generate a contact force. The U-shaped arc plate pushes the arc plate along the inner wall of the device body away from the outer wall of the rotating rod through the contact force. Then the arc plate is reset by the spring force.

[0007] According to the above technical solution, springs are provided between the two arc-shaped plates and the main body of the device, and the arc-shaped plates are located outside the contact plate. The arc surfaces of the several U-shaped arc plates are all located on the movement trajectory of the contact plate. A smoke-proof device is provided below the arc plates to prevent the smoke generated during the drying process of aluminum foil from obstructing the operator's vision and thus affecting the operator's operation.

[0008] According to the above technical solution, the smoke prevention device includes a transmission belt, a reciprocating screw, a collar, and a smoke removal assembly. The transmission belt is driven and mounted on the right side of the outer wall of the rotating rod. Both ends of the reciprocating screw are rotatably mounted on the inner wall of the device body. The collar is slidably mounted on the outer wall surface of the reciprocating screw through its inner wall. The smoke removal assembly is slidably mounted on the bottom of the inner wall of the device body. When the rotating rod rotates, it drives the reciprocating screw to rotate through the transmission belt. When the reciprocating screw rotates, the collar is restricted by its own reciprocating spiral groove, and the collar has a locking block inside that continuously contacts the inner wall of the reciprocating spiral groove, causing the collar to slide left and right along the outer wall of the reciprocating screw. The collar drives the smoke removal assembly to slide synchronously along the bottom of the inner wall of the device body.

[0009] According to the above technical solution, the reciprocating screw is located below the rotating rod, and the right side of the outer wall of the reciprocating screw is connected to the lower part of the inner wall of the transmission belt. The top of the smoke removal assembly is fixedly installed at the bottom of the outer wall of the collar. The top of the smoke removal assembly is provided with a particulate protection device to prevent particulate matter in the smoke from being difficult to be discharged and remaining inside the main body of the device for a long time.

[0010] According to the above technical solution, the smoke-proof device further includes a fixed plate, a movable wheel, a round rod, and several hollow activated carbon plates. The fixed plate is fixedly installed on the edge of the outer wall of the smoke removal component near the center of the collar. The outer wall of the movable wheel is rotatably installed on the inner wall of the fixed plate, and the outer wall of the movable wheel contacts the bottom of the inner wall of the device body. Both ends of the round rod are fixedly installed on the inner wall of the movable wheel, and an arc-shaped groove is opened on the outer wall of one end of the round rod. Several hollow activated carbon plates are equidistantly and fixedly installed on the outer wall surface of the round rod. The smoke removal component drives the fixed plate to move synchronously, and the fixed plate drives the movable wheel to move synchronously. During the left and right movement, the movable wheel contacts the bottom of the inner wall of the device body and generates friction, thus starting to rotate. When the movable wheel rotates, it drives the round rod to rotate, and the round rod drives the hollow activated carbon plates to rotate.

[0011] According to the above technical solution, the particulate-proof device includes a sliding column, a ring, an L-shaped hollow plate, an L-shaped protective plate, and a connecting frame. The sliding column is slidably installed inside the arc-shaped groove of the round rod at one end near the smoke removal assembly. The inner wall of the ring is fixedly installed at the outer wall of the sliding column. The bottom of the L-shaped hollow plate is fixedly installed at the top of the outer wall of the ring. The bottom of the L-shaped protective plate is slidably installed at the top of the smoke removal assembly. The outer wall of the L-shaped protective plate is fixedly connected to the top of the L-shaped hollow plate near the center of the smoke removal assembly. The bottom of the connecting frame is fixedly installed at the top of the L-shaped protective plate. When the round rod rotates, the arc-shaped groove restricts the sliding column, causing the sliding column to slide back and forth inside the arc-shaped groove and drive the ring to move synchronously. The ring drives the L-shaped hollow plate to move synchronously, and the L-shaped hollow plate drives the L-shaped protective plate to slide synchronously along the top of the smoke removal assembly. Multiple L-shaped protective plates slide synchronously around the air outlet of the smoke removal assembly through the restriction of the connecting frame.

[0012] According to the above technical solution, the particulate-proof device further includes a through rod, a contact ring, a swing plate, and a reset plate. The through rod is disposed inside the hollow activated carbon plate. The contact ring is internally penetrated and fixedly installed on the outer wall surface of the through rod. The outer wall of the swing plate is hinged to the inner wall of the hollow activated carbon plate. The reset plate is fixedly installed between the outer wall of the swing plate and the inner wall of the hollow activated carbon plate. When the ring moves backward, it abuts against one end of the front of the through rod, generating a resisting force. The through rod drives the contact ring to move synchronously and expands the contact area between it and the swing plate. At the same time, the force generated by the movement of the through rod and the contact ring causes the hinge shaft between the swing plate and the hollow activated carbon plate to start rotating. At this time, the swing plate begins to swing backward in an arc shape. The swing plate pulls the reset plate to deform synchronously and automatically resets through the elasticity of the reset plate. This process is repeated.

[0013] According to the above technical solution, one end of the through rod is located on the movement trajectory of the back of the ring, and the outer wall of the through rod is fixedly installed on the side of the swing plate away from the inner wall of the hollow activated carbon plate.

[0014] This invention provides a surface coating drying apparatus for aluminum foil production. It has the following beneficial effects:

[0015] (1) This invention uses a combination of a rotating rod, a slotted frame, a limiting block, a sliding ring, a hot air blower, a contact plate, a limiting rod, a heat-gathering cover, an arc plate, and a U-shaped arc plate to distinguish aluminum foil from static drying. It relies on the centrifugal force of rotation to remove excess moisture from the surface of the aluminum foil, avoiding the risk of increased internal stress and breakage due to prolonged drying time. At the same time, the near and far air blowing of the aluminum foil effectively prevents the local area temperature of the aluminum foil from becoming too high, disrupting the drying thermal balance and causing deformation of the aluminum foil during rotation. Meanwhile, the heat-gathering cover covers the hot air blown out by the hot air blower, and the concave surface of the arc plate during movement gathers the hot air within the rotation range of the aluminum foil. This reduces energy consumption and improves drying efficiency without causing local overheating of the aluminum foil.

[0016] (2) By setting up a smoke-proof device, the present invention expands the absorption range of the smoke-proof device for smoke generated during the aluminum foil drying process due to the surface coating and the organic compounds volatilized by the heat through the cooperation of a rotating rod, transmission belt, reciprocating screw, collar, smoke removal component, fixed plate, moving wheel, round rod and hollow activated carbon plate. This prevents the smoke from obstructing the view and affecting the workers' judgment of the drying process, and prevents the aluminum foil drying time from being too long or too short, thus affecting the drying effect. It also promotes the hollow activated carbon plate to rotate and purify the harmful components in the aluminum oxide smoke generated during the heating process of the aluminum foil, and prevents the harmful components from directly entering the smoke removal component and being emitted to the outside, thereby polluting the processing environment around the main body of the device.

[0017] (3) The present invention, through the setting of the anti-particle device, through the cooperation of the round rod, sliding column, ring, L-shaped hollow plate, L-shaped protective plate, connecting frame, through rod, contact ring, swing plate and reset plate, promotes the suction at the air outlet of the smoke removal component and the L-shaped protective plate to cover the area around the air outlet of the smoke removal component when absorbing smoke, reducing the smoke overflow, and intercepting the particles generated in the smoke due to the insufficient combustion of aluminum foil due to solvent and coating, preventing the particles from flying and adhering everywhere, and avoiding the particles being inhaled by the staff after the observation window is opened; and by relying on the swing plate to swing back and forth inside the hollow activated carbon plate, the frequency of contact between harmful gases and harmful substances in the hollow activated carbon plate is increased, making the absorption frequency of harmful substances by the hollow activated carbon plate more active and ensuring the uniform absorption of harmful substances by the hollow activated carbon plate, and extending the replacement cycle of accessories.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0028] Please see Figures 1-8 One embodiment of the present invention is: a surface coating drying device for aluminum foil production, comprising a device body 1, an observation window 2 on the front of the device body 1, a motor 3 on the left side of the device body 1, a rotating rod 6 rotatably mounted on the inner wall of the device body 1, the left end of the rotating rod 6 penetrating and fixedly mounted on the right side of the output end of the motor 3, and a reciprocating spiral groove opened on the left side of the outer wall of the rotating rod 6, and a plurality of grooving frames 7 equidistantly and fixedly mounted on the outer wall of the rotating rod 6, each of the grooving frames 7 having a limit groove on the inner wall of the side of the grooving frame 7 near the rotating rod 6, the grooving... A limiting block 8 is slidably installed on the outer wall of the frame 7 on the side away from the rotating rod 6. The limiting block 8 is slidably connected to the outer wall of the slotted frame 7 through a slot. A sliding ring 9 is sleeved and slidably installed on the outer wall of the reciprocating spiral groove of the rotating rod 6. A hot air blower 10 is fixedly installed through the outer wall of the sliding ring 9. Two abutment plates 11 are fixedly installed on the outer wall of the hot air blower 10. The two abutment plates 11 are symmetrically distributed about the axis of the hot air blower 10. A limiting rod 12 is slidably installed through the interior of the abutment plate 11. The left end of the limiting rod 12 is fixedly installed inside the main body 1 of the device. On the left side of the wall, a heat-gathering cover 13 is fixedly installed on the right side of the contact plate 11. The slotted frame 7 is located inside the heat-gathering cover 13. Two arc-shaped plates 14 are slidably installed on the left side of the inner wall of the main body 1. Several U-shaped arc plates 15 are fixedly installed at equal intervals on the side of the arc plate 14 near the outer wall of the rotating rod 6. Through the above cooperation, the aluminum foil is dried statically. The centrifugal force of rotation is used to remove the excess moisture remaining on the surface of the aluminum foil, avoiding the risk of increased internal stress and cracking caused by a long drying time. At the same time, the near and far air blowing of the aluminum foil effectively prevents the local area temperature of the aluminum foil from becoming too high, which would break the drying heat balance and cause the aluminum foil to deform during rotation. Through the above cooperation, the heat-gathering cover 13 covers the hot air blown out by the hot air blower 10, and the concave surface of the arc plate 14 gathers the hot air within the rotation range of the aluminum foil during the movement. This reduces energy consumption and improves drying efficiency without causing the local area of ​​the aluminum foil to overheat. The rotating rod 6 drives the aluminum foil to rotate at a relatively slow speed, so that the aluminum foil will not deform while being flung out water droplets.

[0029] Springs are provided between the two arc-shaped plates 14 and the main body 1 of the device, and the arc-shaped plates 14 are located outside the contact plate 11. The arc surfaces of several U-shaped arc plates 15 are all located on the movement trajectory of the contact plate 11. A smoke-proof device 4 is provided below the arc-shaped plates 14 to prevent the smoke generated by the aluminum foil during the drying process from obstructing the operator's vision and thus affecting the operator's operation.

[0030] In use, open the observation window 2 on the front of the main body 1 of the device, move the limiting block 8 away from the center of the slot frame 7, insert the aluminum foil into the slot frame 7 through the slot on the outer wall of the slot frame 7 until the aluminum foil enters the limiting groove. Then, the operator resets the limiting block 8 to block the slot on the outer wall of the slot frame 7. Rotate the slot frame 7 and repeat the above steps. Then close the observation window 2 and start the motor 3. The output end of the motor 3 drives the rotating rod 6 to rotate. The rotating rod 6 drives the slot frame 7 and the limiting block 8 to rotate. The slot frame 7 drives the aluminum foil to rotate. When the rotating rod 6 rotates, it restricts the internal block of the sliding ring 9 through its own reciprocating spiral groove, so that the sliding ring 9 can slide left and right along the outer wall of its reciprocating spiral groove when the rotating rod 6 rotates. The sliding ring 9 drives the hot air blower 10 to move synchronously. At this time, the hot air blower 10 performs regular reciprocating sliding air blowing and drying treatment on the aluminum foil inside the slot frame 7. Through the above cooperation, the aluminum foil is dried by static drying, and the residue on the surface of the aluminum foil is removed by the centrifugal force of rotation. The high moisture content prevents prolonged drying time from increasing internal stress and cracking risk in the aluminum foil. Simultaneously, the near and far airflow during drying effectively prevents localized overheating of the aluminum foil, thus avoiding deformation during rotation. When the hot air blower 10 moves left and right, it drives the contact plate 11 to slide along the outer wall of the limiting rod 12. The contact plate 11 drives the heat-gathering cover 13 towards the slotting frame 7 and envelops it. Simultaneously, the arc surface of the contact plate 11 contacts the arc surface of the outer wall of the U-shaped arc plate 15, generating a resisting force. The U-shaped arc plate 15, through this resisting force, pushes the arc plate 14 along the inner wall of the main body 1 away from the outer wall of the rotating rod 6. Afterward, the arc plate 14 returns to its original position due to spring force. This combination ensures that the heat-gathering cover 13 envelops the hot air blown by the hot air blower 10, and the concave surface of the arc plate 14 concentrates the hot air within the rotation range of the aluminum foil during movement. This reduces energy consumption and improves drying efficiency without causing localized overheating of the aluminum foil.

[0031] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes a smoke prevention device 4;

[0032] The smoke-proof device 4 includes a transmission belt 41, a reciprocating screw 42, a collar 43, and a smoke removal component 44. The transmission belt 41 is mounted on the upper inner wall of the upper part of the inner wall of the rotating rod 6 on the right side. The reciprocating screw 42 is rotatably mounted on the inner wall of the device body 1 at both ends. The collar 43 is slidably mounted on the outer wall surface of the reciprocating screw 42 through the inner wall. The smoke removal component 44 is slidably mounted on the bottom of the inner wall of the device body 1. Through the above cooperation, the smoke removal component 44 expands the absorption range of smoke generated by the surface coating and the organic compounds volatilized by the heat during the aluminum foil drying process, avoids smoke from obscuring the vision and affecting the operator's judgment of the drying process, and prevents the aluminum foil drying time from being too long or too short, thus affecting the drying effect.

[0033] The reciprocating screw 42 is located below the rotating rod 6, and the right side of the outer wall of the reciprocating screw 42 is connected to the lower inner wall of the transmission belt 41. The top of the smoke removal assembly 44 is fixedly installed at the bottom of the outer wall of the collar 43. The top of the smoke removal assembly 44 is provided with a particulate protection device 5 to prevent particulate matter in the smoke from being difficult to be discharged and remaining inside the main body 1 of the device for a long time.

[0034] The smoke removal device 4 also includes a fixed plate 45, a movable wheel 46, a round rod 47, and several hollow activated carbon plates 48. The fixed plate 45 is fixedly installed on the outer edge of the smoke removal assembly 44 near the center of the collar 43. The outer wall of the movable wheel 46 is rotatably installed on the inner wall of the fixed plate 45, and the outer wall of the movable wheel 46 contacts the bottom of the inner wall of the device body 1. Both the front and back ends of the round rod 47 are fixedly installed on the inner wall of the movable wheel 46, and an arc-shaped groove is opened on the outer wall of one end of the front of the round rod 47. Several hollow activated carbon plates 48 are equidistantly and fixedly installed on the outer surface of the round rod 47. Through the above cooperation, the hollow activated carbon plates 48 rotate and purify the harmful components in the aluminum oxide smoke generated during the heating process of aluminum foil, preventing the harmful components from directly entering the smoke removal assembly 44 and being emitted to the outside, thereby polluting the processing environment around the device body 1.

[0035] In use, when the rotating rod 6 rotates, it drives the reciprocating screw 42 to rotate via the transmission belt 41. As the reciprocating screw 42 rotates, its reciprocating spiral groove restricts the collar 43, and the internal locking block of the collar 43 continuously contacts the inner wall of the reciprocating spiral groove, causing the collar 43 to slide left and right along the outer wall of the reciprocating screw 42. The collar 43 drives the smoke removal assembly 44 to slide synchronously along the bottom of the inner wall of the main body 1. This combination expands the absorption range of the smoke removal assembly 44 for smoke generated during the aluminum foil drying process due to the surface coating and the organic compounds volatilized by heat. This prevents smoke from obstructing vision and affecting the operator's judgment of the drying process, thus preventing smoke from obstructing vision during aluminum foil drying. If the drying time is too long or too short, it will affect the drying effect; the smoke removal component 44 drives the fixed plate 45 to move synchronously, and the fixed plate 45 drives the moving wheel 46 to move synchronously. During the left and right movement, the moving wheel 46 contacts the bottom of the inner wall of the device body 1 and generates friction, thus starting to rotate. When the moving wheel 46 rotates, it drives the round rod 47 to rotate, and the round rod 47 drives the hollow activated carbon plate 48 to rotate. Through the above cooperation, the hollow activated carbon plate 48 is prompted to rotate, purify and absorb the harmful components in the aluminum oxide smoke generated during the heating process of aluminum foil, so as to prevent the harmful components from directly entering the smoke removal component 44 and being emitted to the outside, thereby polluting the processing environment around the device body 1.

[0036] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes a particulate repellent device 5;

[0037] The particulate repellent device 5 includes a sliding column 51, a ring 52, an L-shaped hollow plate 53, an L-shaped protective plate 54, and a connecting frame 55. The sliding column 51 is slidably installed inside the arc groove of the round rod 47 at one end near the smoke removal assembly 44. The inner wall of the ring 52 is fixedly installed at the outer wall of the sliding column 51. The bottom of the L-shaped hollow plate 53 is fixedly installed at the top of the outer wall of the ring 52. The bottom of the L-shaped protective plate 54 is slidably installed at the top of the smoke removal assembly 44. The outer wall of the L-shaped protective plate 54 is fixedly connected to the top of the L-shaped hollow plate 53 near the center of the smoke removal assembly 44. The bottom of the connecting frame 55 is fixedly installed at the top of the L-shaped protective plate 54. Through the above cooperation, when the smoke removal assembly 44 is sucked up and smoke is absorbed, the L-shaped protective plate 54 covers the area around the smoke removal assembly 44 to reduce smoke leakage. It also intercepts the particles generated in the smoke due to the incomplete combustion of aluminum foil due to solvent and coating, preventing the particles from flying around and adhering, and avoiding the particles from being inhaled by the staff after the observation window 2 is opened.

[0038] The particulate repellent device 5 also includes a through rod 56, an abutment ring 57, a swing plate 58, and a reset plate 59. The through rod 56 is disposed inside the hollow activated carbon plate 48. The abutment ring 57 is inserted through the through rod 56 and fixedly installed on the outer wall surface of the through rod 56. The outer wall of the swing plate 58 is hinged to the inner wall of the hollow activated carbon plate 48. The reset plate 59 is fixedly installed between the outer wall of the swing plate 58 and the inner wall of the hollow activated carbon plate 48. Through the above cooperation, the swing plate 58 swings back and forth inside the hollow activated carbon plate 48, increasing the frequency of contact between harmful gases entering the hollow activated carbon plate 48 and harmful substances. This makes the absorption frequency of harmful substances by the hollow activated carbon plate 48 more active and ensures the uniform absorption of harmful substances by the hollow activated carbon plate 48, thus extending the replacement cycle of the accessories.

[0039] One end of the through rod 56 is located on the movement trajectory of the back of the ring 52, and the outer wall of the through rod 56 is fixedly installed on the side of the swing plate 58 away from the inner wall of the hollow activated carbon plate 48.

[0040] In use, when the round rod 47 rotates, it restricts the sliding column 51 through the arc groove, causing the sliding column 51 to slide back and forth inside the arc groove and drive the ring 52 to move synchronously. The ring 52 drives the L-shaped hollow plate 53 to move synchronously, and the L-shaped hollow plate 53 drives the L-shaped protective plate 54 to slide synchronously along the top of the smoke removal assembly 44. Multiple L-shaped protective plates 54 are restricted by the connecting frame 55 to slide synchronously around the air outlet of the smoke removal assembly 44. Through the above cooperation, when the smoke removal assembly 44 air outlet is sucked and absorbed, the L-shaped protective plate 54 covers the area around the air outlet of the smoke removal assembly 44 to reduce smoke leakage, and intercepts the particles generated in the smoke due to the incomplete combustion of aluminum foil due to solvent and coating, preventing the particles from flying and adhering everywhere, and avoiding the particles being inhaled by the staff after the observation window 2 is opened; the ring 52 moves towards When the rod moves backward, it generates a resisting force at one end of the front of the through rod 56. The through rod 56 drives the resisting ring 57 to move synchronously and expands the contact area between it and the swing plate 58. At the same time, the force generated by the movement of the through rod 56 and the resisting ring 57 causes the swing plate 58 to start rotating on the hinge shaft between itself and the hollow activated carbon plate 48. At this time, the swing plate 58 begins to swing backward in an arc shape. The swing plate 58 pulls the reset piece 59 to deform synchronously and automatically resets through the elasticity of the reset piece 59. This process is repeated. Through the above cooperation, the swing plate 58 swings back and forth inside the hollow activated carbon plate 48, increasing the frequency of contact between harmful gases and harmful substances in the hollow activated carbon plate 48. This makes the absorption frequency of harmful substances by the hollow activated carbon plate 48 more active and ensures the uniform absorption of harmful substances by the hollow activated carbon plate 48, thus extending the replacement cycle of the parts.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
