[0002] Aluminum foil is a hot stamping material that is directly rolled into thin sheets from metallic aluminum. It is commonly used in biomedicine, new energy power batteries, etc.

[0003] Aluminum foil needs to be cooled during the production process. In order to solve the defect of slow cooling efficiency of traditional cooling chambers, some cooling devices are used in the existing technology to speed up the cooling of aluminum foil. For example, the patent with publication number "CN 214307860U" discloses a cooling device for medicinal composite filter aluminum foil. In this patented technical solution, cooling is performed by combining air cooling and cooling plates. Although it has a high cooling efficiency, the friction between the aluminum foil and the cooling plate is large, which easily scratches the surface of the aluminum foil contacting the cooling plate. In order to avoid scratching the aluminum foil, there are some solutions in the existing technology. For example, the patent with publication number "CN216745063U" discloses a rapid cooling device for aluminum foil production. In this patented technical solution, the aluminum foil is directly cooled by passing through the coolant, which avoids the aluminum foil from being scratched. However, this method brings the problem of how to remove the coolant on the aluminum foil. Summary of the Invention

DETAILED DESCRIPTION

[0022] Example 1

[0023] An aluminum foil cooling device includes a winding roller 1 and two guide rollers 2. After the aluminum foil 21 comes out of the previous process, it is wound around the guide roller 2 and is wound by the winding roller 1. It is easy to understand that the winding roller 1 rotates actively and the two guide rollers 2 rotate passively. In addition, it should be understood that the accompanying drawings only show the positions of the winding roller 1 and the guide rollers 2. In actual applications, they can be supported and fixed by a frame (not shown).

[0024] A cooling box 3 is provided between the two guide rollers 2. It should be understood that the aluminum foil 21 passes through the cooling box 3. An annular heat-conducting belt 4 is provided in the cooling box 3. The annular heat-conducting belt 4 contacts the lower surface of the aluminum foil 21 for heat exchange, thereby achieving the purpose of cooling the aluminum foil 21. The annular heat-conducting belt 4 is made of a material with good thermal conductivity, such as thermally conductive rubber or other similar materials.

[0025] A cooling box 8 is provided below the annular heat-conducting belt 4. The cooling box 8 contains a coolant. The bottom of the annular heat-conducting belt 4 contacts the top of the cooling box 8. It is worth noting that the present invention cools the annular heat-conducting belt 4 by means of the coolant, and then uses the annular heat-conducting belt 4 to contact the lower surface of the aluminum foil 21 for heat exchange, so that the aluminum foil 21 does not come into contact with the coolant, thereby avoiding the problem of how to remove the coolant on the aluminum foil 21 (i.e., there is no need to set up a corresponding coolant removal mechanism to remove the coolant on the aluminum foil 21 to ensure that the aluminum foil 21 is dry). Furthermore, an input pump 9 for inputting coolant is provided at one end of the cooling box 8, and a discharge pump 10 for discharging coolant is provided at the other end of the cooling box 8. Coolant is continuously inputted through the input pump 9, and the discharge pump 10 continuously discharges the coolant after heat exchange, thereby ensuring that the bottom of the annular heat-conducting belt 4 can be well cooled.

[0026] The annular heat-conducting belt 4 is wrapped around a driving roller 5 and at least one driven roller 6 to form a structure similar to a conveyor belt. The driving roller 5 is connected to a driving component 7, which drives the driving roller 5 to rotate, thereby driving the annular heat-conducting belt 4 to rotate. In this embodiment, the linear velocity of the heat-conducting belt is equal to the linear velocity of the aluminum foil 21. It is worth noting that such an arrangement prevents relative motion between the annular heat-conducting belt 4 and the aluminum foil 21, thereby preventing the aluminum foil 21 from being scratched due to friction at the contact point between the annular heat-conducting belt 4 and the aluminum foil 21.

[0027] The specific method for achieving the linear velocity of the annular heat conducting belt 4 being equal to the linear velocity of the aluminum foil 21 in this embodiment is as follows: the diameter of the drive roller 5 is the same as the diameter of one of the guide rollers 2. It is worth noting that this arrangement ensures that when the rotational speeds of the drive roller 5 and the guide roller 2 are the same, the linear velocity of the annular heat conducting belt 4 is the same as the linear velocity of the aluminum foil 21. In this embodiment, the guide roller 2 is the guide roller 2 close to the winding roller 1 (it is easy to understand that other embodiments may also select another guide roller 2). Based on the above, the driving component 7 includes a belt 702 and two pulleys 701, one of which is connected to the guide roller 2 and the other is connected to the driving roller 5. The two pulleys 701 are connected by the belt 702. In this arrangement, when the guide roller 2 rotates in accordance with the movement of the aluminum foil 21, it will drive the driving roller 5 to rotate via the belt 702. Furthermore, the diameters of the two pulleys 701 are equal to ensure that the rotational speeds of the driving roller 5 and the guide roller 2 are consistent.

[0028] The winding roller 1 is connected to a groove wheel 11, and a dial 12 is provided on one side of the groove wheel 11 (similarly, in actual application, the dial 12 can be fixed by a frame support), and the dial 12 is connected to a motor (not shown) for driving it to rotate. The center of the dial 12 is fixedly connected to a shift rod 13, and the end of the shift rod 13 is provided with a shift pin 14 for cooperating with the radial groove on the groove wheel 11, that is, the groove wheel 11, the dial 12 and the shift pin 14 constitute the groove wheel 11 mechanism. When the dial 12 rotates under the drive of the motor (it is easy to understand that a deceleration mechanism can also be provided so that the output speed of the motor is decelerated and acts on the dial 12), it drives the groove wheel 11 to rotate in a gap. Such a setting makes it easy to extend the contact time between the aluminum foil 21 and the annular conductive belt 4, so that the aluminum foil 21 is fully cooled.

[0029] On the basis of the above, the cooling box 3 of this embodiment is further provided with an air collecting box 15 inside. The air collecting box 15 has a cavity inside. The bottom of the air collecting box 15 is provided with a plurality of nozzles 16. The air collecting box 15 is connected to an air supply pipe 17. The air supply pipe 17 is connected to a hair dryer (not shown). During operation, cold air is blown in by the hair dryer, enters the cavity of the air collecting box 15 through the air supply pipe 17, and is then discharged by the nozzle 16, thereby cooling the upper surface of the aluminum foil 21. That is, the present invention combines the two cooling methods of heat exchange and blowing of the annular heat conducting belt 4 to achieve higher cooling efficiency. An exhaust port 301 is provided on one side of the cooling box 3 to facilitate air discharge. Furthermore, the exhaust port 301 is connected to an exhaust fan (not shown) to accelerate the exhaust efficiency of the air.

[0030] In this embodiment, the air collecting box 15 is arranged directly above the annular heat conducting belt 4, that is, each nozzle 16 is opposite to the annular heat conducting belt 4. With this arrangement, on the one hand, the annular heat conducting belt 4 plays a role in cooling the aluminum foil 21, and on the other hand, the annular heat conducting belt 4 also plays a role in supporting the aluminum foil 21 to prevent the aluminum foil 21 from being broken due to excessive wind force.

[0031] In this embodiment, the cavity is provided with a number of partitions 18 at intervals along the conveying direction of the aluminum foil 21. The partitions 18 divide the cavity air into a number of sub-air cavities 151. The nozzles 16 are provided at the bottom of the sub-air cavities 151. It is easy to understand that the bottom of each sub-air cavity 151 is provided with a number of nozzles 16 along the width direction of the aluminum foil 21. The top of each sub-air cavity 151 is connected to a connecting pipe 19. A sub-air duct 20 connected to the air supply duct 17 is provided above the air collecting box 15. Each connecting pipe 19 is connected to the sub-air duct 20. It is worth noting that the cavity is divided into a plurality of sub-air cavities 151, and the wind is dispersed into each sub-air cavities 151 through the sub-air cavities 151, so that the wind at each position along the length direction of the aluminum foil 21 is more uniform, thereby improving the cooling effect.

[0032] Example 2

[0033] The difference between this embodiment and the first embodiment is that the method of achieving the linear velocity of the movement of the annular conductive belt 4 being equal to the linear velocity of the movement of the aluminum foil 21 is different. Specifically, the driving component 7 of this embodiment includes a speed sensor, a controller, a servo driver and a servo motor. The controller is a PLC controller, and the speed sensor, servo driver and servo motor can be conventional ones.

[0034] The servo motor is connected to the driving roller 5, and the speed sensor is configured to collect the linear speed of the movement of the aluminum foil 21 or the angular speed of rotation of one of the guide rollers 2. In this embodiment, the speed sensor is a rotation angular speed sensor, which is installed on one of the guide rollers 2 to collect the angular speed of the guide roller 2. The controller is configured to receive the data collected by the speed sensor and control the servo driver to adjust the output speed of the servo motor, thereby adjusting the speed of the driving roller 5 in real time according to the change in the linear speed of the aluminum foil 21 during the winding process of the aluminum foil 21, thereby ensuring that the linear speed of the annular conductive belt 4 is equal to the linear speed of the aluminum foil 21.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
