Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment, and in particular to a high-efficiency shearing and slitting machine for the production of rolled copper foil. Background Technology

[0002] Rolled copper foil is a high-precision copper foil produced through a rolling process. It is made from high-purity electrolytic copper through multiple processes such as casting and cold rolling. It is widely used in high-end electronic and new energy fields such as flexible circuit boards, lithium battery electrodes, and 5G components. It is a key basic material for ensuring product performance in the electronic information and new energy industries.

[0003] The high-efficiency shearing and slitting machine for rolled copper foil production is a slitting device specifically designed for high-precision and easily damaged materials such as rolled copper foil. It can accurately slit wide copper foil rolls into narrow specifications. Through a precision tension control device and a high-hardness wear-resistant blade assembly, it ensures that the copper foil does not produce wrinkles, burrs, or tensile deformation during high-speed slitting. It is widely used in lithium batteries, flexible circuit boards and other fields, and is a key piece of equipment for improving the production efficiency and yield of rolled copper foil.

[0004] In some existing technology devices, some high-efficiency shearing and slitting machines for the production of rolled copper foil use a guide structure with a fixed gap, which makes it difficult to flexibly adjust the clamping force according to the thickness of the copper foil. Excessive gap causes the copper foil to shift and wrinkle. In addition, the tension adjustment is a rigid mechanical structure, which makes it difficult to release the internal stress of the copper foil through elastic buffering, causing the copper foil to stretch and deform or loosen and accumulate, resulting in slitting accuracy. Therefore, a high-efficiency shearing and slitting machine for the production of rolled copper foil is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a high-efficiency shearing and slitting machine for the production of rolled copper foil, which aims to improve the problems of rigid adjustment in some existing devices being unable to cope with tension fluctuations and release the internal stress of copper foil.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency shearing and slitting machine for producing rolled copper foil includes a frame, an unwinding mechanism fixedly connected to the top of the frame, and a slitting mechanism fixedly connected to the top of the frame.

[0008] The unwinding mechanism includes two copper coil support columns. The bottom of the copper coil support columns is fixedly connected to the top of the frame. A copper coil shaft is rotatably connected to the adjacent side of the two copper coil support columns. A copper coil roller is fixedly connected to the outside of the copper coil shaft. Two material guide support columns are fixedly connected to the top of the frame. An adjusting screw is threaded to the top of the material guide support columns. A movable block is threaded to the bottom of the adjusting screw. A movable roller is rotatably connected to the adjacent side of the two movable blocks. A fixed slider is fixedly connected to the top of the frame. A tension assembly is fixedly connected to the top of the frame.

[0009] As a further description of the above technical solution:

[0010] The tension assembly includes two tension support columns. The bottom of the tension support columns is fixedly connected to the top of the frame. A spring is fixedly connected inside the tension support column. An adjusting block is fixedly connected to the bottom of the spring. An adjusting shaft is rotatably connected to the adjacent side of the two adjusting blocks. An adjusting roller is fixedly connected to the outside of the adjusting shaft.

[0011] As a further description of the above technical solution:

[0012] The slitting mechanism includes two slitting support columns, the bottom of which is fixedly connected to the top of the frame. Fixed rollers are rotatably connected to adjacent sides of the two slitting support columns. A motor is fixedly connected to the rear side of the slitting support columns. A slitting shaft is fixedly connected to the drive end of the motor. Two slitting cutters are fixedly connected to the outside of the slitting shaft. A collecting assembly and a winding assembly are fixedly connected to the top of the frame.

[0013] As a further description of the above technical solution:

[0014] The collection assembly includes a fan, the bottom of which is fixedly connected to the top of the frame. An air duct is provided inside the slit support column. Two debris inlets are provided at the top of the slit support column. A collection box is fixedly connected to the rear side of the slit support column. A collection groove is provided inside the collection box. A protective net is fixedly connected to the rear side of the collection box.

[0015] As a further description of the above technical solution:

[0016] The winding assembly includes two winding support columns, the bottom of which is fixedly connected to the top of the frame. A winding shaft is rotatably connected to the adjacent side of the two winding support columns, and a winding roller is fixedly connected to the outside of the winding shaft.

[0017] As a further description of the above technical solution:

[0018] The movable block is externally slidably connected to the inside of the material guide support column, and both ends of the movable roller are slidably connected to the inside of the material guide support column;

[0019] As a further description of the above technical solution:

[0020] The external part of the adjusting block is slidably connected to the inside of the tension support column, and both ends of the adjusting shaft are slidably connected to the inside of the tension support column.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, screwing in or out the adjusting screw allows the movable block to slide within the guide support column, thereby adjusting the gap between the movable roller and the fixed slider. The copper foil contacts the outside of the adjusting roller, applying an upward force to the adjusting roller, causing it to rise. This, in turn, drives the adjusting block to rise, which in turn drives the spring to rise. Simultaneously, the spring applies a downward force to the adjusting block, preventing it from rising and thus preventing the copper foil from rising. This reduces material wrinkles and stacking under the clamping action and spring tension compensation, making the copper foil flatter, increasing the accuracy of shearing and slitting, and further ensuring quality.

[0025] 2. In this utility model, the air generated by the fan acts on the debris inlet through the air duct, forming a negative pressure environment at the debris inlet. The debris generated during the copper foil slitting process enters the debris inlet, then enters the air duct, and then enters the collection box. The air exits through the protective net, and the debris remains in the collection trough, realizing the timely collection of debris during the copper foil slitting process and reducing the interference of debris on the processing.

[0040] Working principle: During the preparation for cutting and slitting copper foil, the adjusting screw 25 is adjusted and calibrated according to the copper foil. By screwing the adjusting screw 25 in or out, the movable block 26 can slide within the guide support column 24, thereby adjusting the gap between the movable roller 27 and the fixed slider 28. The copper foil is released from the copper coil roller 23 and enters the space between the movable roller 27 and the fixed slider 28 to adjust the tension. Then it comes into contact with the outside of the adjusting roller 295. The copper foil applies an upward force to the adjusting roller 295, causing the adjusting roller 295 to rise. This, in turn, drives the adjusting block 293 to rise, which in turn drives the spring 292 to rise. At the same time, the spring 292 applies a downward force to the adjusting block 293, preventing the adjusting block 293 from rising, and thus preventing the copper foil from rising.

[0041] When cutting and slitting copper foil, the height and flatness of the copper foil are adjusted by adjusting roller 295 to fixed roller 32, and then slitting by slitting cutter 35. The slitting copper foil is then wound up by winding roller 373. The air generated by fan 361 acts on the debris inlet 363 through air duct 362, creating a negative pressure environment at the debris inlet 363. The debris generated during the copper foil slitting process enters the debris inlet 363, then enters the air duct 362, and then enters the collection box 364. The air exits through protective net 366, and the debris remains in collection trough 365.
