Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of copper foil production and processing, in particular to a rolling device for copper foil production. Background Art
[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil precipitated on the substrate of the circuit board, which serves as the conductor of the PCB. It is easy to adhere to the insulating layer, accept the printed protective layer, and form a circuit pattern after corrosion. Copper foil is made of copper and a certain proportion of other metals. Copper foil generally has two types: 90% foil and 88% foil, that is, copper content is 90% and 88%, and the size is 16*16cm. It is the most widely used decorative material. For example: hotels, temples, Buddha statues, golden signs, ceramic tile mosaics, handicrafts, etc. In the existing copper foil production and processing process, a rolling device is required to roll the copper foil.
[0003] However, the existing rolling device lacks a cooling structure when rolling the copper foil. This results in a large amount of heat generated by the copper foil due to friction and deformation during the rolling process. Specifically, when the copper foil is tightly pressed by the pressing roller in the rolling mechanism, due to the friction between the pressing roller and the copper foil and the plastic deformation of the copper foil itself, significant heat is generated. This heat accumulation will cause the temperature of the copper foil to rise rapidly. If this heat cannot be dissipated in a timely and effective manner, the copper foil may become overheated. Excessive temperature may cause changes in the performance of the copper foil or uneven pressing results, thereby affecting the rolling effect of the copper foil. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Example 1, please refer to Figure 1-4 The utility model provides a technical solution: a rolling device for copper foil production, comprising a device body 1, a cooling fan 107 is fixedly installed on the top of the device body 1, a first air outlet duct 108 is fixedly connected to the rear side of the cooling fan 107, a duct joint 109 is fixedly connected to the other end of the first air outlet duct 108, second air outlet ducts 110 are fixedly embedded at the centers of both sides of the duct joint 109, a conveying rack 111 is fixedly installed at the other ends of the two second air outlet ducts 110, the outer surfaces of the two second air outlet ducts 110 are fixedly embedded in the interior of the device body 1, a plurality of nozzles 112 are fixedly installed at the centers of the opposite sides of the two conveying racks 111, and the two conveying racks 111 are fixedly installed. It is fixedly installed on the inner wall of the device body 1, and first pressure rollers 101 are movably embedded on both sides of the interior of the device body 1 near the bottom. Two slide grooves 102 are provided on both sides of the inner wall of the device body 1, and the four slide grooves 102 are divided into two groups. The inner surfaces of the two groups of slide grooves 102 are slidably connected with first flanges 103, and second pressure rollers 104 are movably embedded in the two first flanges 103. Screws 105 are threadedly connected at both ends of the top side of the interior of the device body 1, and the bottom outer surfaces of the two screws 105 are movably embedded in the top center of the first flange 103. Crank handles 106 are fixedly installed on the top of the two screws 105, and conveying rollers 2 are movably embedded at both ends of the left side of the interior of the device body 1.
[0031] In this embodiment, one end of the copper foil is first picked up and placed on the top of the first pressing roller 101, and the crank handle 106 is turned forward to drive the screw 105 to rotate, so that the screw 105 can move downward while rotating, thereby pushing the first flange 103 to slide downward on the inner surface of the slide groove 102. When the first flange 103 moves downward, it can drive the second pressing roller 104 to move synchronously, so that the second pressing roller 104 is in contact with the top of the copper foil, and the second pressing roller 104 continues to press down, thereby squeezing the copper foil to deform it, and pulling one end of the copper foil to pass through the bottom of the right conveying roller 2 and at the same time stick to the top of the left conveying roller 2, and then continue to pull the copper foil to make it stick to the bottom of the winding roller 203, and rotate the winding roller 203 to rewind the copper foil. When the device body 1 is rolling the copper foil, the power supply system of the cooling fan 107 can be started. The air cooler 107 can transport cold air to the inside of the pipe joint 109 through the first air outlet duct 108 when the air cooler 107 is in operation, and disperse and transport the cold air through the pipe joint 109, so that the cold air enters the inside of the conveying frame 111 through the second air outlet duct 110, and then the cold air is transported by the conveying frame 111 to the inside of the nozzle 112, and the nozzle 112 blows the cold air to the upper and lower surfaces of the copper foil for heat dissipation. In addition, through the structures such as the air cooler 107 and the screw 105, the device body 1 can not only adjust the gap between the first pressing roller 101 and the second pressing roller 104, so that the device can control the deformation degree of the copper foil during the pressing process, and improve the flexibility of the device, but also through the combination of the air cooler 107 and the nozzle 112, it can quickly blow cold air to the surface of the copper foil, quickly reduce the temperature of the copper foil, speed up the cooling speed, and help to quickly solidify and stabilize the deformation of the copper foil.
[0032] Embodiment 2, as Figure 1-4 As shown, a gantry 201 is fixedly installed on the left side of the top of the device body 1, a rotating rod 202 is movably embedded inside the gantry 201, a winding roller 203 is fixedly sleeved on the outer surface of the rotating rod 202, a motor 204 is fixedly installed on the rear side of the rotating rod 202, telescopic columns 205 are fixedly installed at both ends of the top side of the inner wall of the gantry 201, and reset springs 206 are fixedly installed at both ends of the top side of the inner wall of the gantry 201, the inner surfaces of the two reset springs 206 are movably sleeved on the outer surfaces of the telescopic columns 205, a second flange 207 is fixedly installed on the bottom of the two reset springs 206 and the two telescopic columns 205, and a third pressure roller 208 is movably embedded inside the second flange 207.
[0033] In this embodiment, after the copper foil adheres to the bottom of the winding roller 203, the motor 204 can be started through the power supply system of the motor 204, so that when the motor 204 is running, the winding roller 203 is driven to rotate synchronously through the rotating rod 202 on the gantry 201, and the copper foil is rolled up. When the copper foil is rolled up, the copper foil will adhere to the bottom of the third pressing roller 208, and at the same time, the third pressing roller 208 is pushed up, so that when the third pressing roller 208 moves upward, the telescopic column 205 and the return spring 206 are squeezed through the second flange 207 to shrink, so that the third pressing roller 208 always adheres to the outer surface of the copper foil, and through the third pressing roller 208 and the telescopic column 205 and other structures, the device keeps the third pressing roller 208 in contact with the surface of the copper foil during the copper foil rolling process, which can effectively control the copper foil rolling process, reduce quality problems such as looseness, curling or wrinkles, and improve the uniformity and compactness of the rolling.
[0034] Working principle: When in use, first pick up one end of the copper foil and place it on the top of the first pressing roller 101, and turn the crank 106 forward to drive the screw 105 to rotate, so that the screw 105 can move downward while rotating, thereby pushing the first flange 103 to slide downward on the inner surface of the slide groove 102. When the first flange 103 moves downward, it can drive the second pressing roller 104 to move synchronously, so that the second pressing roller 104 is attached to the top of the copper foil, and the second pressing roller 104 continues to press down, thereby squeezing the copper foil to deform it, and pulling one end of the copper foil to pass through the bottom of the right conveying roller 2 and stick to the top of the left conveying roller 2, and then continue to pull the copper foil to make it stick to the bottom of the winding roller 203, and rotate the winding roller 203 to reel the copper foil. When the device body 1 is rolling the copper foil, it can be powered by the power supply system of the cooling fan 107. Start the air cooler 107, so that when the air cooler 107 is running, the cold air is transported to the inside of the pipe joint 109 through the first air outlet duct 108, and the cold air is dispersed and transported through the pipe joint 109, so that the cold air enters the inside of the conveying frame 111 through the second air outlet duct 110, and then the cold air is transported by the conveying frame 111 to the inside of the nozzle 112, and the nozzle 112 blows air to the upper and lower surfaces of the copper foil for heat dissipation. In addition, through the structures such as the air cooler 107 and the screw 105, the device body 1 can not only adjust the gap between the first pressing roller 101 and the second pressing roller 104, so that the device can control the deformation degree of the copper foil during the pressing process, and improve the flexibility of the device, but also through the combination of the air cooler 107 and the nozzle 112, cold air can be quickly blown to the surface of the copper foil, the temperature of the copper foil is quickly reduced, the cooling speed is accelerated, and it is helpful to quickly solidify and stabilize the deformation of the copper foil. When in use, after the copper foil adheres to the bottom of the winding roller 203, the motor 204 can be started through the power supply system of the motor 204, so that when the motor 204 is running, the winding roller 203 is driven to rotate synchronously through the rotating rod 202 on the gantry 201, and the copper foil is rolled up. When the copper foil is rolled up, the copper foil adheres to the bottom of the third pressing roller 208, and the third pressing roller 208 is pushed up at the same time, so that when the third pressing roller 208 moves upward, the telescopic column 205 and the return spring 206 are squeezed through the second flange 207 to shrink, so that the third pressing roller 208 always adheres to the outer surface of the copper foil, and through the third pressing roller 208 and the telescopic column 205 and other structures, the device keeps the third pressing roller 208 in contact with the surface of the copper foil during the copper foil rolling process, which can effectively control the copper foil rolling process, reduce quality problems such as looseness, curling or wrinkles, and improve the uniformity and compactness of the rolling.
