[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: a drying device for copper foil production, including a box body 1, a telescopic frame 2 is fixedly installed at the bottom of the box body 1, two groups of sponge pinch rollers 19 are movably installed inside the box body 1 through shaft seats, two outer guide rollers 3 are movably installed on the outer sides of both ends of the box body 1, two inner guide rollers 18 are movably installed on the inner sides of both ends of the box body 1, a first air guide roller 9 is movably installed inside the box body 1 through the side wall by a bearing, a second air guide roller 10 is movably installed inside the box body 1 through the side wall by a bearing, driven meshing gears 11 are fixedly sleeved on the outer sides of one ends of the first air guide roller 9 and the second air guide roller 10, a driving gear 12 meshes with the bottom of the outer side of the driven meshing gear 11, one end of the driving gear 12 is drivingly connected to a servo motor 13, sponge roller sleeves 22 are sleeved on the outer sides of the first air guide roller 9 and the second air guide roller 10, a second sealing bearing 24 is sleeved on the inner side of one end of the first air guide roller 9, a first connecting pipe 5 is sleeved on the inner side of the second sealing bearing 24, the other end of the first connecting pipe 5 is communicated with an air suction pump 4, a first sealing bearing 23 is sleeved on the inside of one end of the second air guide roller 10, a second connecting pipe 8 is sleeved on the inner side of the first sealing bearing 23, the other end of the second connecting pipe 8 is communicated with an air outlet pump 7, the input end of the air outlet pump 7 is communicated with a heating box 6, a plurality of resistance heating wires 21 are fixedly installed inside the heating box 6, a leftward blower 15 is installed on the top of the inner cavity of the box body 1 through a bracket, a rightward blower 16 is installed on the bottom of the inner cavity of the box body 1 through a bracket, two resistance heaters 17 are fixedly installed on the bottom of the inner cavity of the box body 1, a plurality of heat conducting strips 20 are fixedly installed on the bottom of the inner cavity of the box body 1, and a drain pipe 14 is communicated with one end of the bottom of the box body 1.
[0020] Working principle of the above technical solution: When in use, pass the copper foil through the box body 1, through the outer guide roller 3 and the inner guide roller 18 at one end of the box body 1, and through the sponge pinch roller 19, so that the copper foil is clamped on the opposite sides of the sponge roller sleeves 22 outside the first air guide roller 9 and the second air guide roller 10. Finally, it is limited and led out through the outer guide roller 3 and the inner guide roller 18 at the other end of the box body 1. When the equipment operates, the air pump 7 extracts the air flow inside the heating box 6. The resistance heating wire 21 inside the heating box 6 heats the air. The hot air enters the inside of the second connecting pipe 8 through the air pump 7, and then is introduced into the inside of the second air guide roller 10. Through the air holes with air in the second air guide roller 10 and the diversion of the sponge roller sleeve 22, the air flow is evenly blown to the outside of the copper foil. At the same time, the suction pump 4 sucks the air flow through the first connecting pipe 5. The air flow enters through the air holes with air in the first air guide roller 9. The air flow is evenly diverted by the sponge roller sleeve 22 outside the first air guide roller 9 and enters. The air flow at the position where the copper foil is heated and dried is extracted, so that the water vapor and heat can be taken out, which is convenient for drying the outside of the copper foil. Cooperating with the sponge pinch roller 19 to clamp and absorb the water vapor on the outside of the copper foil improves the drying efficiency.
[0021] In another embodiment, as Figures 1-4 shown, the two outer guide rollers 3 and the inner guide rollers 18 are symmetrically and evenly distributed at both ends of the box body 1. The two ends of the box body 1 are provided with inlet and outlet slots, and the two groups of sponge pinch rollers 19 are symmetrically and evenly distributed inside the box body 1.
[0022] The outer guide roller 3 and the inner guide roller 18 can guide and limit the copper foil entering and leaving the inside of the box body 1, avoiding damage, increasing the guiding and protection. The inlet slot allows the copper foil to enter and exit, facilitating the operation.
[0023] In another embodiment, as Figure 1 shown, the servo motor 13 is fixedly installed on the outside of the box body 1 through a bracket.
[0024] After the servo motor 13 is fixed, it can drive the driving gear 12 to rotate. The driving gear 12 drives the engaged driven meshing gear 11 to rotate. The two engaged driven meshing gears 11 make the first air guide roller 9 and the second air guide roller 10 clamp and drive the copper foil in one direction, facilitating the rotation and balancing of the air flow during the suction and blowing processes, increasing the uniformity of the suction and blowing, and facilitating the use.
[0025] In another embodiment, as Figures 1-4 shown, a number of air holes are provided inside both the first air guide roller 9 and the second air guide roller 10, and one end of the first air guide roller 9 and the second air guide roller 10 is in a sealed state.
[0026] The uniform distribution of the first air guide roller 9 and the second air guide roller 10 in the air holes enables the uniform entry and discharge of air flow, enhancing the overall usage effect and facilitating the operation of the air flow. With one end blocked, the air flow can be guided in a defined direction, facilitating the cooperative operation.
[0027] In another embodiment, as Figures 1-4 shown, the suction pump 4 is fixedly installed on the top of the box body 1, and both the heating box 6 and the air outlet pump 7 are fixedly installed on the top of the box body 1. An air inlet is provided on one side of the heating box 6.
[0028] After the suction pump 4 is fixed, it is convenient to suck the air flow through the first connecting pipe 5. The fixation of the heating box 6 and the air outlet pump 7 facilitates the heated air flow to be blown into the interior of the second air guide roller 10 through the second connecting pipe 8. The position of the air inlet corresponds to that of the resistance heating wire 21 and is located in the middle of the resistance heating wire 21, facilitating the uniform contact of the air flow with the resistance heating wire 21 when entering the interior of the heating box 6, facilitating the uniform heating of the air flow, improving the heating efficiency, and having a good usage effect.
[0029] In another embodiment, as Figure 3 and Figure 4 shown, the resistance heater 17 is located on the back of the rightward blower 16. The leftward blower 15 and the rightward blower 16 are opposite in direction. The heat conducting strips 20 are linearly and uniformly arranged at the bottom of the inner cavity of the box body 1, and the heat conducting strips 20 are located on the opposite side of the rightward blower 16 and the drain pipe 14.
[0030] By setting the leftward blower 15 and the rightward blower 16, the resistance heater 17 heats the hot air flow driven by the rightward blower 16 after heating the resistance heater 17. The air flow blows towards the leftward blower 15 at the bottom of the inner cavity of the box body 1, while the leftward blower 15 blows the air flow towards the rightward blower 16 at the top of the inner cavity of the box body 1. The leftward blower 15 and the rightward blower 16 form a convection inside the box body 1, enabling the hot air flow to circulate inside the box body 1, increasing the efficiency of the air flow drying cycle and removing water vapor. By setting the heat conducting strips 20 and the drain pipe 14, when there is too much water droplets inside the box body 1, the sponge pinch roller 19 at one end absorbs and squeezes the droplets that drip inside the box body 1 and discharges them through the drain pipe 14. The heat conducting strips 20 can conduct heat. In the subsequent implementation process, by connecting a refrigerator to the heat conducting strips 20, the heat conducting strips 20 can intercept and condense the water vapor in the circulating air flow, facilitating the water vapor diversion, reducing the internal water vapor content, and improving the drying efficiency.
[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
