Description

Technical Field

[0001] The utility model relates to the technical field of copper foil production, in particular to a copper foil cutting device. Background Technique

[0002] Copper foil is a kind of cathode electrolytic material, a thin and continuous metal foil deposited on the base layer of a circuit board, which serves as the conductor of a 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 by adding a certain proportion of other metals to copper. Generally, there are two types of copper foil, 90 foil and 88 foil, that is, the copper content is 90% and 88%, and the size is 16*16cm copper foil, which is the most widely used decorative material. Such as: hotels, temple statues, gold lettered signs, ceramic mosaics, handicrafts, etc.

[0003] In the process of copper foil production, it is necessary to cut the slit copper foil strip to meet the subsequent production. However, the existing cutting devices cannot cut multiple copper strips at the same time, and the current conventional copper foil slitting method is an up-and-down cutting knife cutting mechanism. Most of the conveying mechanisms are difficult to adjust, so it is difficult to cope with the cutting of copper foils with different specifications and thicknesses, thus affecting the production efficiency. Based on this, a copper foil cutting device is proposed. Content of the Utility Model

[0020] Working principle of the above technical solution: During use, the operator places the copper strip on the top of the conveyor belt 13 and adjusts the height of the clamping roller 4 through the adjusting mechanism 3, so that the clamping roller 4 clamps the copper strip on the top of the conveyor belt 13. Then, the second servo motor 16 and the first servo motor 17 are started. The second servo motor 16 drives the upper cutting roller 11 to rotate, and drives the lower cutting roller 18 to rotate through the transmission meshing gear 10, so that the cutting knife 15 and the cutting boss groove 19 gradually coincide and rotate. At the same time, the first servo motor 17 rotates to drive the transmission roller 8 to rotate, and drives the conveyor belt 13 sleeved on the outside to rotate to convey the copper strip. When the copper strip is on the opposite side of the cutting boss groove 19 and the cutting knife 15, the cutting knife 15 and the cutting boss groove 19 coincide relative to each other in the groove 14 to cut the copper strip. As the rotation progresses, the copper strip is conveyed out for collection. The relative positions of the clamping roller 4 and the transmission roller 8 can be adjusted through the adjusting mechanism 3 and the hydraulic telescopic rod 7, and the relative positions of the upper cutting roller 11 and the lower cutting roller 18 can be adjusted by inserting bolts inside the sliding clamping plate two 9.

The extension of the hydraulic telescopic rod 7 facilitates the adjustment of the height of the transmission roller 8.

[0023] In another embodiment, as Figure 1 and Figure 2 shown, the position of the clamping roller 4 corresponds to the position of the transmission roller 8. The adjusting mechanism 3 includes a sliding frame, a slider, a shaft seat and a bolt. The shaft seat is fixedly installed on the opposite side of the slider, the slider is slidably installed inside the sliding frame, and the bolt passes through the sliding frame and is threadedly connected to the inside of the top end of the slider.

[0025] In another embodiment, asFigures 1 - 4 As shown, the grooves 14 are linearly and evenly distributed inside the conveyor belt 13. The cutting knives 15 and the cutting boss grooves 19 are both circumferentially and evenly distributed outside the upper cutting roller 11 and the lower cutting roller 18. The positions of the cutting knives 15 correspond to the positions of the cutting boss grooves 19, and the specification dimensions of the grooves 14 are adapted to the specification dimensions of the cutting boss grooves 19.

[0026] The distribution of the grooves 14 corresponds to the positions of the cutting boss grooves 19. The height of the cutting boss grooves 19 is flush with the outer side of the conveyor belt 13 and is the same as the size of the grooves 14, which is convenient for the transmission and support of the copper strip. The cutting knives 15 and the cutting boss grooves 19 gradually coincide with each other as the upper cutting roller 11 and the lower cutting roller 18 rotate.
