Description

Technical Field

[0001] The present invention relates to a drying device, and more specifically, to a drying device for copper foil after water washing. Background Art

[0002] During the production process of copper foil, copper powder and other impurities will be deposited on the surface of the copper foil. In order to remove these impurities, water washing is required to ensure the quality of the copper foil. At the same time, the copper foil needs to be dried quickly after water washing to remove the moisture remaining on the surface to avoid affecting the quality of the finished copper foil.

[0003] In the existing drying process, after the copper foil is washed, it is horizontally conveyed through a heating device for drying. In this current conveying method, most of the moisture on the lower surface of the copper foil will form water droplets and drip by itself under the action of gravity during the conveying process, while the moisture on the upper surface is difficult to eliminate and will accumulate and cause residue, resulting in the moisture content on the upper surface of the copper foil being greater than that on the lower surface. When the copper foil passes through the heating device, the drying rates of the upper and lower surfaces are different, which can easily lead to insufficient heating of the upper surface or excessive heating of the lower surface, affecting the production quality of the copper foil.

DETAILED DESCRIPTION

[0028] See also Figure 1-6 As shown, a drying device for copper foil after washing of the present invention comprises a frame 1, characterized in that a feed roller 2 and a discharge roller 3 for conveying copper foil are respectively arranged at both ends of the frame 1, and the feed roller 2 and the discharge roller 3 are both arranged vertically; two groups of lifting roller groups 4 that are inclined and rotate upward are arranged on the frame 1 between the feed roller 2 and the discharge roller 3, and an angle adjustment component 5 that is inclined downward and matched with the lifting roller group 4 is arranged on the frame 1. A steering roller is arranged between the external washing device and the feed roller to turn the copper foil from horizontal to vertical, and the steering roller is a prior art and will not be described here. The copper foil is conveyed vertically by the vertically arranged feed roller and discharge roller, so that most of the water droplets on both sides of the copper foil can be eliminated under the action of gravity, ensuring that the water content on both sides of the copper foil is basically the same, so that the drying efficiency of the two sides of the copper foil is the same when the copper foil is heated and dried, and the drying quality of the two sides is consistent.

[0029] The lifting roller group rotates in the same direction as the feed roller and the discharge roller and slightly upwards. The copper foil moves upwards while passing through the lifting roller group, so that the copper foil will not fall down during the vertical transportation process, which can effectively keep the copper foil taut and avoid displacement of the copper foil.

[0030] A water spray assembly 6 tilted downward and tangent to the surface of the lifting roller group 4 is provided on the frame 1 on the side of the feed roller 2, and a plurality of drainage grooves 7 are provided on the frame 1; a heating assembly 8 is provided between the two lifting roller groups 4, and a cooling air duct 9 is provided on the frame 1 on the side of the discharge roller 3. The lifting roller group arranged on the side of the feed roller can clean a small amount of colloid remaining after washing while lifting the copper foil. The nozzle of the water spray assembly tilts downward and tangent to the surface of the lifting roller group away from the copper foil. The water spraying direction is opposite to the rotation direction of the lifting roller group, which can effectively wash away a small amount of impurities attached to the lifting roller group.

[0031] A box plate covering the above-mentioned components is arranged on the rack to form a relatively closed box space as a whole, which can reduce the pollution caused by the water mist sprayed by the water spray component spreading to the external environment and reduce the heat loss of the heating component. At the same time, it can prevent light garbage, dust, etc. in the external environment from floating onto the copper foil and causing pollution. The relatively closed space can prevent people from directly contacting the equipment and copper foil, thereby improving safety.

[0032] In this embodiment, preferably, the angle α between the lifting roller set 4 and the vertical plane is 5-8°. Through experiments, it is found that when the angle α between the lifting roller set and the vertical plane is 5-8°, it can ensure that the copper foil will not sag downward, and the lifting speed will not be too fast, so that the copper foil will not be torn while ensuring the copper foil is transported.

[0033] In this embodiment, preferably, the lifting roller group 4 includes a mounting frame 4a arranged on the frame 1, guide grooves 4b are arranged at both ends of the mounting frame 4a, two sliding seats 4c that slide relatively are arranged in each guide groove 4b, and a self-tensioning assembly 10 is arranged between the sliding seats 4c; a lifting roller 4d is arranged on the sliding seat 4c through a bearing, and a driving assembly is connected to the upper end of the lifting roller 4d. The upper end of the lifting roller is located outside the box body, and a corresponding long hole for making way is arranged on the box body. The driving assembly is arranged outside the box body to avoid being affected by water mist. The driving assembly is composed of a motor and a plurality of transmission gears arranged on the mounting frame. Its specific structure and connection method are the prior art that can be easily thought of by those skilled in the art, and will not be repeated here.

[0034] By providing a self-tensioning component, the copper foil can be kept in a tensioned state during transportation, thus avoiding wrinkles in the copper foil.

[0035] Further preferably, the self-tensioning assembly 10 includes at least one guide rod 10a arranged on each sliding seat 4c, and the guide rod 10a cooperates with the mounting frame 4a through a shaft sleeve; a tensioning spring 10b is sleeved on the guide rod 10a between the sliding seat 4c and the mounting frame 4a.

[0036] A push plate 10c is connected between the upper and lower sliding seats 4c on the same side, and an adjusting cylinder 10d is provided on the side wall of the mounting frame 4a, and the piston rod of the adjusting cylinder 10d is connected to the push plate 10c. During operation, the piston rod of the adjusting cylinder on one side pushes inward to make the two lifting rollers clamp the copper foil to keep the copper foil tensioned. When the inclination angle of the lifting roller needs to be adjusted, the cylinder piston rod on the other side pulls the lifting roller on one side outward to make the lifting roller leave the copper foil surface by 0.5-1.5mm, so as to avoid wrinkling or tearing the copper foil when the lifting roller changes its angle. And because the displacement distance of the lifting roller is 0.5-1.5mm, which is much smaller than the gear tooth size of the transmission gear in the drive assembly, the transmission gear can still mesh for transmission after displacement.

[0037] In this embodiment, the angle adjustment assembly 5 includes a movable hinge seat 5a and a lifting adjustment assembly 11 respectively hinged at both ends of the bottom of the lifting roller group 4 along the advancing direction of the copper foil; a movable guide rail 5b matching the movable hinge seat 5a is provided on the frame 1; a two-dimensional movable assembly 12 sliding horizontally and vertically above the frame 1, and the top of the lifting roller group 4 is hinged on the two-dimensional movable assembly 12. The movable hinge seat is composed of a guide rail and a sliding seat arranged on the frame, and in this embodiment, it is preferably arranged in the drainage groove to reduce the distance between the bottom of the lifting roller group and the surface of the frame, so that the space at the bottom is more compact.

[0038] In this embodiment, preferably, the lifting and adjusting component 11 includes a vertical through hole 11a provided on the frame 1, a mounting plate 11b is provided on the frame 1 at the bottom of the vertical through hole 11a, a bearing 11c aligned with the vertical through hole 11a is provided on the mounting plate 11b, a rotating sleeve 11d with an external hexagonal free end is provided on the bearing 11c, a screw rod 11e hinged to the two-dimensional moving component 12 is connected in the rotating sleeve 11d by a thread; a limiter component 13 for preventing the rotating sleeve 11d from rotating is detachably provided at the bottom of the mounting plate 11b. The lifting roller group is tilted by rotating the rotating sleeve to adjust the height of the screw rod, and the rotating sleeve and the screw rod are connected by relatively fine threads. When the rotating sleeve rotates one circle, the tilt angle of the lifting roller group changes by 1°. The specific setting of the thread lead angle and the spacing is common knowledge of those skilled in the art and will not be repeated here.

[0039] When the rotating sleeve is rotated into place, its rotation is limited by the limit assembly to prevent the vibration generated during the operation of the lifting roller group from causing the rotating sleeve to rotate slightly and causing the screw rod to move, thereby preventing the lifting roller group from changing its inclination angle and causing the copper foil to be torn.

[0040] Further preferably, the limiting assembly 13 includes a polygonal positioning seat 13a, a positioning groove 13b having a size larger than the free end of the rotating sleeve 11d is provided on the positioning seat 13a, and a plurality of vertically arranged adaptive ejector pins 13c are evenly distributed on the bottom of the positioning groove 13b. The adaptive ejector pins cooperate with the rotating sleeve, so that the adaptive ejector pins can fit with the side wall of the rotating sleeve to limit its rotation no matter to which angle the rotating sleeve rotates.

[0041] On both sides of the bottom of the mounting plate 11b, there are symmetrically arranged limit baffles 13d matching the outer wall of the positioning seat 13a, on which are arranged guide rails 13e, on which are arranged elastic ejector pins 13f matching the guide rails 13e, on which are arranged the outer wall of the positioning seat 13a, and at the proximal end of the upper end of the guide rail 13e on one side, there is arranged a positioning hole 13g matching the elastic ejector pin 13f. With this structure, the positioning seat can be quickly disassembled and assembled.

[0042] In this embodiment, preferably, the two-dimensional moving assembly 12 comprises a horizontal guide rod 12a arranged above the frame 1, a sliding sleeve 12b is arranged on the horizontal guide rod 12a, and quick-locking pipe hoops 12c are arranged at both ends of the sliding sleeve 12b; a vertical sleeve 12d is arranged on the sliding sleeve 12b, and a lifting rod 12e hinged to the lifting roller group 4 is arranged in the vertical sleeve 12d, and a limit ring 12f is arranged on the upper end of the lifting rod 12e. The sliding sleeve is locked by the quick-locking pipe hoop to prevent the sliding sleeve from moving due to the vibration generated during the operation of the lifting roller group, and to avoid affecting the tilt angle of the lifting roller.

[0043] In this embodiment, preferably, the heating assembly 8 comprises a mounting frame 8a arranged on both sides of the copper foil, a plurality of heating lamps 8b are evenly distributed on the mounting frame 8a, and a uniform heating net 8c is provided at the front end of the heating lamp 8b; and a tension roller group 8d for clamping the copper foil is provided on the frame 1 on both sides of the mounting frame 8a. The uniform heating net evenly disperses the heat emitted by the heating lamp, so that the copper foil is evenly heated, which can ensure that the drying efficiency of each part of the copper foil remains consistent.

[0044] In this embodiment, a mounting suspension 14 is provided on the frame 1 at the upper end of the feed roller 2, and a speed measuring wheel 15 matching the copper foil is provided on the mounting suspension 14. A speed sensor is provided inside the speed measuring wheel 15 and connected to an external data terminal. The external data terminal is connected to the driving component of the lifting roller group, and the forward speed of the copper foil is detected in real time through the speed measuring wheel, and the external data terminal controls the lifting roller group to maintain the same speed, so as to avoid the copper foil being torn due to speed difference.

[0045] During operation, the copper foil cleaned by the washing equipment is transported from horizontal to vertical through the steering roller and then transported through the feed roller, lifting roller group, tension roller group, lifting roller group and discharge roller. During the transportation process, the copper foil is dried by the heating lamps on both sides. Before reaching the discharge roller for discharge, the copper foil is cooled by the cooling air ducts on both sides.

[0046] The above embodiments are preferred implementation modes of the present invention and are only used to facilitate the description of the present invention. They are not intended to limit the present invention in any form. Any person with ordinary knowledge in the relevant technical field, if they do not depart from the scope of the technical features of the present invention, can make equivalent embodiments by partial changes or modifications to the technical contents disclosed in the present invention, and they still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
