Description

Technical Field

[0001] The invention relates to the technical field of foil production machines, in particular to air drying equipment for cathode rollers. Background Art

[0002] A foil machine is a device used to produce thin films. Its principle is to chemically deposit metal or non-metallic materials onto a substrate to form a thin film. The machine primarily consists of a deposition chamber, a liquid supply system, a gas supply system, a control system, and a winding system. The deposition chamber is the core component, consisting of electrodes, a power supply, a reaction solution, and a substrate. The liquid supply system is responsible for providing the reaction solution, while the gas supply system is responsible for providing the reaction gases. The control system is responsible for controlling various parameters of the foil machine, such as temperature, humidity, and current. The winding system is responsible for winding up the produced film.

[0003] The foil production machine utilizes an electrochemical reaction to deposit metal or non-metallic materials onto a substrate to form a thin film. In the deposition chamber, energizing the electrodes causes a reduction reaction of metal ions in the reaction solution, forming a thin film. Simultaneously, the reactive gases provided by the gas supply system control the thickness and properties of the film. The resulting film is then wound into a finished product by a winding system and can be used in the production of various film products.

[0004] The periphery of the cathode roller of the foil machine also includes a water receiving box, an acid squeezing roller, an acid squeezing roller, a water washing pipe, a water squeezing roller, and an air drying duct arranged in sequence. The acid squeezing roller is used to squeeze the liquid on the cathode roller and then guide it outward through the water receiving box. The acid squeezing roller is then used to squeeze the acid squeezing roller and squeeze out the excess liquid. The water washing pipe then sprays water to rinse the copper foil, while the water squeezing roller squeezes the water out of the surface of the copper foil. Finally, air is blown through the air drying duct and acts on the copper foil. Currently, the common air drying ducts include air inlet pipes at both ends. After the air inlet pipe blows compressed air into the air drying duct, the air is blown out through multiple air outlets opened on the air drying duct. However, since the air inlet pipes are arranged at intervals and the air outlets are also arranged at intervals, some copper foils are blown with greater force and degree, while some are blown with less effect, resulting in poor overall air drying effect of the copper foil. Summary of the Invention

[0005] In view of this, an object of the present invention is to provide an air drying device for a cathode roller to solve the technical problems existing in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention provides a drying device for a cathode roller, comprising an air drying pipe body, several blast branch pipes connected to the air drying pipe body, and a blast main pipe, wherein the blast main pipe is connected to the air inlet ends of all the blast branch pipes, and a long strip air outlet is horizontally opened on the side of the air drying pipe body, and the air outlet is directly facing a cathode roller.

[0007] Furthermore, the longitudinal cross-section of the air drying pipe body is arc-shaped, and an arc-shaped air flow channel is formed between the inner wall of the air outlet pipe body and the outer wall of the cathode roller. The air outlet is connected to the top of the air flow channel. A circulation chamber is opened inside the air drying pipe body, and the air blower branch pipe and the air outlet are both connected to the circulation chamber.

[0008] Furthermore, a first guide portion with a triangular longitudinal section and a second guide portion with a strip-shaped longitudinal section are horizontally arranged in the circulation chamber, both ends of the first guide portion and the second guide portion are connected to the two ends of the circulation chamber, the bottom of the second guide portion is connected to the inner cavity of the circulation chamber close to the cathode roller, and there is a set distance between the top and the inner cavity of the circulation chamber, the first guide portion is arranged at the corner of the top of the circulation chamber close to the cathode roller, and an inclined guide channel is formed between the lower side of the first guide portion and the upper side of the second guide portion, and the bottom of the guide channel is connected to the air outlet.

[0009] Furthermore, the air blast branch pipe is connected to the bottom of the air drying pipe body, and a first balancing plate is horizontally arranged in the circulation chamber. Both ends of the first balancing plate and the side away from the cathode roller are connected to the inner wall of the circulation chamber, and there is a set gap between the side close to the cathode roller and the inner wall of the circulation chamber.

[0010] Furthermore, a second balancing plate is horizontally arranged in the circulation chamber, and both ends of the second balancing plate and the side close to the cathode roller are connected to the inner wall of the circulation chamber, and there is a set gap between the side away from the cathode roller and the inner wall of the circulation chamber, and the second balancing plate is higher than the first balancing plate.

[0013] Furthermore, the adjusting member is spherical, and three mutually connected ventilation holes are opened through the adjusting member. The three ventilation holes are distributed in the XYZ directions, and each of the ventilation holes passes through the center of the adjusting member.

[0014] The beneficial effects of the air-drying equipment for cathode rollers provided by the present invention are as follows: when the cathode roller is air-dried, the main air blast pipe introduces compressed air into each air blast branch pipe, and then after entering the air-drying pipe body, it is blown out through the long air outlet and acts on the copper foil; since the air in the main air blast pipe is introduced into the air-drying pipe body through multiple air blast branch pipes, the air can be distributed more evenly when entering the air-drying pipe body; secondly, since the air outlet is long, the copper foil facing the air-drying pipe body can be dried, and the air-drying effect is better.

[0021] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1 to 5 As shown,

[0023] A drying device for a cathode roller comprises an air drying pipe body 1, several blast branch pipes 2 connected to the air drying pipe body 1, and a blast main pipe 3, wherein the blast main pipe 3 is connected to the air inlet ends of all the blast branch pipes 2, and a long strip-shaped air outlet 4 is horizontally opened on the side of the air drying pipe body 1, and the air outlet 4 is opposite to a cathode roller 5, wherein the cathode roller 5 does not belong to the structure of the air drying equipment and is introduced here only for auxiliary explanation.

[0024] The longitudinal cross-section of the air drying pipe body 1 is arc-shaped, and an arc-shaped air flow channel 6 is formed between the inner wall of the air outlet pipe body and the outer wall of the cathode roller 5. The air outlet 4 is connected to the top of the air flow channel 6. A circulation chamber 7 is opened inside the air drying pipe body 1, and the air blower branch pipe 2 and the air outlet 4 are both connected to the circulation chamber 7.

[0025] A first guide portion 8 with a triangular longitudinal section and a second guide portion 9 with a strip-shaped longitudinal section are horizontally arranged in the circulation chamber 7. Both ends of the first guide portion 8 and the second guide portion 9 are connected to the two ends of the circulation chamber 7. The bottom of the second guide portion 9 is connected to the inner cavity of the circulation chamber 7 on one side close to the cathode roller 5, and there is a set distance between the top and the inner cavity of the circulation chamber 7. The first guide portion 8 is arranged at the corner of the top of the circulation chamber 7 close to the cathode roller 5, and an inclined guide channel 10 is formed between the lower side of the first guide portion 8 and the upper side of the second guide portion 9. The bottom of the guide channel 10 is connected to the air outlet 4.

[0026] The blast branch pipe 2 is connected to the bottom of the air drying pipe body 1, and a first balancing plate 11 is horizontally arranged in the circulation chamber 7. Both ends of the first balancing plate 11 and the side away from the cathode roller 5 are connected to the inner wall of the circulation chamber 7, and there is a set gap between the side close to the cathode roller 5 and the inner wall of the circulation chamber 7 (wherein descriptors similar to "set gap", "set interval" or similar in this application all express that the two structures are in a non-contact state, and the specific size of the gap or the size of the distance can be selected according to the actual situation).

[0027] A second balancing plate 12 is also horizontally arranged in the circulation chamber 7. Both ends of the second balancing plate 12 and the side close to the cathode roller 5 are connected to the inner wall of the circulation chamber 7. There is a set gap between the side away from the cathode roller 5 and the inner wall of the circulation chamber 7. The second balancing plate 12 is higher than the first balancing plate 11.

[0028] A third equalizing plate 13 is also horizontally arranged in the circulation chamber 7. The four sides of the third equalizing plate 13 are connected to the inner wall of the circulation chamber 7. A plurality of through holes 14 are vertically opened through the third equalizing plate 13. The third equalizing plate 13 is higher than the second equalizing plate 12.

[0029] An adjustment plate 15 is also horizontally arranged in the circulation chamber 7. The adjustment plate 15 is located between the third balancing plate 13 and the second guide portion 9. A plurality of adjustment holes 16 are opened on the adjustment plate 15. The top of each adjustment hole 16 is provided with a trumpet-shaped adjustment cover 17 which is small at the top and large at the bottom. An adjustment member 18 is movably provided in each adjustment cover 17. The movable range of the adjustment member 18 is between the top of the adjustment cover 17 and the third balancing plate 13.

[0030] The adjusting member 18 is spherical, and three mutually connected vent holes 19 are formed through the adjusting member 18 . The three vent holes 19 are distributed in the XYZ directions, and each of the vent holes 19 passes through the center of the adjusting member 18 .

[0031] When the cathode roller 5 is air-dried, the main air blast pipe 3 introduces compressed air into each air blast branch pipe 2, and then after entering the air-drying tube body 1, it is blown outward through the long air outlet 4 and acts on the copper foil; since the air in the main air blast pipe 3 is introduced into the air-drying tube body 1 through multiple air blast branch pipes 2, the air can be distributed more evenly when entering the air-drying tube body 1; secondly, since the air outlet 4 is long, the copper foil facing the air-drying tube body 1 can be dried, and the drying effect is better.

[0032] The compressed air enters the blast branch pipe 2 through the blast main pipe 3, then enters the bottom of the air drying pipe body 1 through multiple blast branch pipes 2, and enters the space between the air drying pipe body 1 and the first equalizing plate 11 in the circulation chamber 7. After being affected by the first equalizing plate 11, the air is evenly distributed. After passing between the first equalizing plate 11 and the inner wall of the circulation chamber 7, it flows upward, which can achieve a primary equalization effect on the air. That is, if the air pressure at a certain point is higher, it can be affected by the lower part of the first equalizing plate 11 and, to a certain extent, guide the higher air pressure to the surrounding area, so that the lower pressure air on both sides can increase in pressure and be closer to equilibrium with the higher pressure area.

[0033] Similarly, when the air passes through the first balancing plate 11 and flows to the second balancing plate 12, the second balancing plate 12 can also play a balancing role on the air and make the air pressure further balanced. In this way, the air entering between the second balancing plate 12 and the third balancing plate 13 can be closer to balance.

[0034] Moreover, when the air flows to the third balancing plate 13, the air can be balanced again through the holes 14, and the air can be further balanced. After the air passes through the third balancing plate 13, if the air flow rate in some part is relatively high and the pressure is still relatively high, a relatively large force will be applied to the regulating member 18. The regulating member 18 is made of a material with a relatively low density and can be moved upward by the air. At this time, if the air flow rate at a certain point is relatively high, the upward force of the air will also be relatively large, so that the regulating member 18 can be raised and abutted against the inner wall of the regulating cover 17. At this time, the air can only flow upward through the vent holes 19. On the contrary, if the air flow rate at a certain point is relatively low, the degree of raising the regulating member 18 is also relatively small, so that the resistance of the air circulation regulating plate 15 is relatively small, and the air can flow upward normally.

[0035] Therefore, the overall effect is that the areas with high air velocity experience greater resistance, thus slowing down their flow and reducing their pressure; while the areas with low air velocity and low air pressure experience less resistance, facilitating upward flow; this can again balance the gas and make the air flow more evenly upward.

[0036] When the air flows upward, it will first bypass the top of the second guide part 9. While being balanced by the second guide part 9 (the principle is the same as that of the first balancing plate 11), it can also guide the airflow. That is, after the air enters the guide channel 10, it flows downward at an angle and finally flows downward through the air outlet 4. Since the guide channel 10 is inclined downward, the air also flows downward when it flows out of the air outlet 4. In this way, the air can blow the copper foil in one direction without the airflow canceling each other out, thus ensuring the wind effect.

[0037] Moreover, since the air drying tube body 1 is inclined, the air flow channel 6 is also arc-shaped, and the air is connected to the top of the air flow channel 6. In this way, the air can act on the copper foil for a longer time during the flow process, resulting in better air drying effect and higher air drying efficiency.

[0038] During use, the three air vents 19 in the XYZ directions ensure that even if the adjusting member 18 is attached to the inner wall of the adjusting cover 17, air can still flow upward through a certain air vent; secondly, the bottom of the adjusting member 18 is supported by the third balancing plate 13, and the top cannot pass through the adjusting cover 17, thus ensuring the stability of the adjusting member 18; in actual use, adjacent adjusting covers 17 are connected first in sequence, thus ensuring the stability of the adjustment; secondly, the top opening of the adjusting cover 17 is opposite to the lower side of the second guide part 9, so that the second guide part 9 can have a better air balancing effect.

[0039] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
