Description

Technical Field

[0001] The invention relates to the technical field of drying, in particular to a surface coating drying device for aluminum foil production. Background Art

[0002] Metal-shell packaged lithium-ion batteries tend to release gas during use, and increased pressure leads to explosion. With the continuous advancement of scientific research, a soft packaging material containing aluminum foil and aluminum-plastic composite film for lithium batteries has been introduced to effectively release battery pressure and reduce the risk of battery explosion.

[0003] Patent announcement number CN114992994B discloses a top coating drying device for aluminum foil production, comprising a drying box, wherein a plurality of groups of symmetrically arranged support plates are fixedly connected to both sides of the inner wall of the drying box; wherein, adjusting rods are slidably connected to both sides of the inner wall of the drying box, a plurality of groups of pressing plates are fixedly connected to the outer wall of the adjusting rod, a plurality of screw rods are rotatably connected to the inner wall of the drying box, the screw rods are driven by a motor, and a locking assembly is provided on the adjusting rod; a movable plate is threadedly connected to the screw rod, an air storage cylinder is connected to the movable plate, and a nozzle connected thereto is provided on the air storage cylinder; the nozzle on the air storage cylinder is driven to move back and forth by a movable frame to dry and blow away the moisture on the aluminum foil, thereby reducing the moisture remaining on the aluminum foil and improving the uniformity of drying; at the same time, the upper and lower sides of the aluminum foil are dried by the nozzle, thereby reducing the problem of slow drying speed on the back of the aluminum foil and improving the drying efficiency.

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

[0005] In view of the deficiencies in the prior art, the present invention provides a surface coating and drying device for aluminum foil production, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above purpose, the present invention is implemented through the following technical solutions: a surface coating and drying device for aluminum foil production, including a device body, an observation window is arranged on the front of the device body, a motor is arranged on the left side of the device body, a rotating rod is rotatably installed on the inner wall of the device body, the left end of the rotating rod passes through and is fixedly installed on the right side of the motor output end, and a reciprocating spiral groove is opened on the left side of the outer wall of the rotating rod, a plurality of slotted frames are equidistantly and fixedly installed on the outer wall of the rotating rod, and a plurality of the slotted frames are all provided with limiting grooves on the inner walls close to the rotating rod side, and a limiting block is slidably installed on the outer wall of the slotted frame away from the rotating rod side, The limit block is slidably connected to the outer wall of the slotted frame through a slot, the outer wall of the reciprocating spiral groove of the rotating rod is sleeved and slidably installed with a sliding ring, the outer wall of the sliding ring passes through and is fixedly installed with a hot air blower, and two contact plates are fixedly installed on the outer wall of the hot air blower, and the two contact plates are symmetrically distributed about the axis of the hot air blower, and a limit rod is passed through and slidably installed inside the contact plate, the left end of the limit rod is fixedly installed on the left side of the inner wall of the device body, and a heat collecting cover is fixedly installed on the right side of the contact plate, the slotted frame is located on the inner side of the heat collecting cover, and two arc plates are slidably installed on the left side of the inner wall of the device body, and the arc plate is close to the rotating A number of 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 device body, move the limit block away from the center of the slot frame, insert the aluminum foil into the slot frame through the slot on the outer wall of the slot frame until the aluminum foil enters the limit slot, and the staff resets the limit block to cover the slot on the outer wall of the slot frame, rotate the slot frame in turn and repeat the above steps, then close the observation window and start the motor. The output end of the motor drives the rotating rod to rotate, the rotating rod drives the slot frame and the limit block to rotate, the slot frame drives the aluminum foil to rotate, and when the rotating rod rotates, it uses its own reciprocating spiral groove to contact the block inside 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, and the sliding ring drives the hot air blower to move synchronously. At this time, the hot air blower performs regular reciprocating sliding blowing and drying treatment on the aluminum foil inside the slotted frame; when the hot air blower moves left and right, it drives the resistance plate to slide along the outer wall of the limit rod, and the resistance plate drives the heat collecting cover to move toward the slotted frame and cover the slotted frame. At the same time, the arc surface of the resistance plate will contact the arc surface of the outer wall of the U-shaped arc plate to generate a resistance force. The U-shaped arc plate pushes the arc plate to slide along the inner wall of the device body away from the outer wall of the rotating rod through the resistance force, and then the arc plate is reset by the elastic force of the spring.

[0007] According to the above technical solution, a spring is arranged between the two arc plates and the device body, and the arc plate is located outside the contact plate. The arc surfaces of several U-shaped arc plates are located on the movement trajectory of the contact plate.

The inner wall of the ring penetrates and is slidably installed on the surface of the outer wall of the reciprocating screw. The bottom of the smoke removal assembly is slidably installed on the bottom of the inner wall of the device body. When the rotating rod rotates, the reciprocating screw is driven to rotate through the transmission of the transmission belt. When the reciprocating screw rotates, the ring is restricted by its own reciprocating spiral groove, and a block inside the ring continuously contacts the inner wall of the reciprocating spiral groove to enable the ring to slide left and right along the outer wall of the reciprocating screw. The ring 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 transmission-connected to the lower part of the inner wall of the transmission belt. The top of the smoke removal assembly is fixedly installed on the bottom of the outer wall of the ring. The top of the smoke removal assembly is provided with an anti-particle device for preventing particulate matter in the smoke from being difficult to discharge and remaining inside the device body for a long time.

[0010] According to the above technical scheme, the anti-smoke device also includes a fixed plate, a moving wheel, a round rod and a plurality of 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 ring. The outer wall of the moving wheel is rotatably installed on the inner wall of the fixed plate. The outer wall of the moving wheel contacts the bottom of the inner wall of the device body. Both the front and back ends of the round rod are fixedly installed on the inner wall of the moving wheel, and an arc groove is provided on the outer wall of the front end of the round rod. Several of the hollow activated carbon plates are equidistant 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 moving wheel to move synchronously. During the left and right movement, the moving wheel contacts the bottom of the inner wall of the device body to generate friction and starts to rotate. When the moving wheel rotates, it drives the round rod to rotate, and the round rod drives the hollow activated carbon plate to rotate.

[0011] The outer wall of the L-shaped hollow plate is fixedly mounted on the top of the outer wall of the ring; the bottom of the L-shaped protective plate is slidably mounted on the top of the smoke removal component; the outer wall of the L-shaped protective plate is fixedly mounted on the top of the outer wall of the ring; the bottom of the L-shaped protective plate is slidably mounted on the top of the smoke removal component; 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 component; the bottom of the connecting frame is fixedly mounted on the top of the L-shaped protective plate; when the round rod rotates, the arc groove restricts the sliding column, so that the sliding column can slide back and forth in the arc groove and drive the ring to move synchronously; the ring drives the L-shaped hollow plate to move synchronously; the L-shaped hollow plate drives the L-shaped protective plate to slide synchronously along the top of the smoke removal component; and multiple L-shaped protective plates are restricted by the connecting frame to achieve synchronous sliding around the air outlet of the smoke removal component.

[0012] According to the above technical scheme, the anti-particle device also includes a penetrating rod, a resistance ring, a swinging plate and a reset plate. The penetrating rod is arranged inside the hollow activated carbon plate, and the resistance ring penetrates inside and is fixedly installed on the outer wall surface of the penetrating rod. The outer wall of the swinging plate is hinged at the inner wall of the hollow activated carbon plate, and the reset plate is fixedly installed between the outer wall of the swinging plate and the inner wall of the hollow activated carbon plate. When the circular ring moves backward, it resists the front end of the penetrating rod to generate a resistance force, and the penetrating rod drives the resistance ring to move synchronously and expand the contact area with the swinging plate. At the same time, the swinging plate causes the hinge axis between itself and the hollow activated carbon plate to start rotating through the force generated by the movement of the penetrating rod and the resistance ring. At this time, the swinging plate starts to swing backward in an arc shape, and the swinging plate pulls the reset plate to deform synchronously and automatically resets through the elastic force of the reset plate, and this process repeats.

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

At the same time, the aluminum foil is dried by blowing air far and near to effectively prevent the local area temperature of the aluminum foil from being too high, breaking the drying heat balance and causing the aluminum foil to deform during the rotation process; at the same time, the heat collecting hood is used to cover the hot air blown out by the hot air blower, and the concave surface of the arc plate itself gathers the hot air within the rotation range of the aluminum foil during the movement, thereby reducing energy loss and improving drying efficiency without causing overheating of the local area of ​​the aluminum foil.

[0016] (2) The present invention expands the absorption range of the smoke removal component for smoke generated by the surface coating and the organic compounds volatilized by the heat during the drying process of the aluminum foil by setting up a smoke prevention device through the coordination of a rotating rod, a transmission belt, a reciprocating screw, a sleeve ring, a smoke removal component, a fixed plate, a moving wheel, a round rod and a hollow activated carbon plate, thereby preventing the smoke from blocking the vision and affecting the judgment of the drying process by the staff, and preventing the aluminum foil from being dried for too long or too short, thereby affecting the drying effect; and promoting the hollow activated carbon plate to rotate, purify and absorb harmful components in the aluminum oxide smoke generated by the aluminum foil during the heating process, thereby preventing the harmful components from directly entering the smoke removal component and being discharged to the outside, thereby polluting the processing environment around the device body.

[0017] (3) The present invention sets an anti-particle device, and cooperates with round rods, sliding columns, circular rings, L-shaped hollow plates, L-shaped protective plates, connecting frames, through rods, abutment rings, swinging plates and reset plates to promote suction at the air outlet of the smoke removal component and to cover the air outlet of the smoke removal component to reduce smoke overflow when absorbing smoke. It also intercepts particles in the smoke generated by incomplete combustion of aluminum foil, solvent and coating to prevent particles from flying around and adhering, thereby preventing particles from being inhaled by workers after the observation window is opened. It also relies on the swinging plate to swing back and forth inside the hollow activated carbon plate to increase the frequency of contact between harmful gases entering the hollow activated carbon plate and harmful substances, thereby promoting the hollow activated carbon plate to absorb harmful substances more actively and ensuring the hollow activated carbon plate to absorb harmful substances evenly, thereby extending the replacement cycle of accessories.
