Electrolytic copper foil equipment fly cutter device

[0026] Such as figure 1 , figure 2 , image 3 Shown is a schematic structural diagram of the flying knife device of the electrolytic copper foil equipment of the present invention, including a power source, a transmission assembly and a knife bar assembly. The power source is a variable frequency motor 1, and the main driving wheel 2 is arranged at the power output end of the variable frequency motor 1; the transmission assembly It includes two main driving wheels 2, a feed sprocket 4, a rotating sprocket 5, a rotating drum 12, a rolling screw 8, and a rolling nut 15. The rotating drum 12 is a hollow long cylinder with a feed slot 13 in the axial direction, Its two ends are respectively supported by bearings; the rolling screw 8 is coaxially arranged in the rotating cylinder 12 and the two ends are respectively rotatably connected with the rotating cylinder 12 through a self-aligning bearing 7; the rolling nut 15 can rotate under the driving of the rolling screw 8 The cylinder 12 moves along the axial direction of the rolling screw 8; two main driving wheels 2 are fixed side by side on the output shaft of the power source; the feed sprocket 4 and the rotating sprocket 5 pass through the transmission chain 14 and a main driving wheel 2 respectively The feed sprocket 4 and the rolling screw 8 are coaxially connected by the clutch 6; the rotating sprocket 5 is rotatably connected with the feed sprocket 4 through the self-aligning bearing 7 and is firmly connected to the rotating drum 12; the main driving wheel 2 and the feed A tension sprocket 3 is provided between the feed sprocket 4 and a tension sprocket 3 is provided between the main driving wheel 2 and the rotating sprocket 5.

[0027] An independent variable frequency motor is used, and two independent sprockets are used to rotate respectively. The two-stage sprockets use the speed difference ratio to achieve transmission difference, cleverly realize the low-speed rotation and feed movement of the equipment, which is beneficial to the main parts of the equipment. Stable operation, extending the service life of the equipment.

[0028] The flying knife device of the electrolytic copper foil equipment also includes a control mechanism, which includes a travel switch and a displacement sensor arranged between the rotating drum and the rolling screw. The control mechanism adopts the travel switch and displacement sensor positioning, which effectively avoids the occurrence of safety accidents.

[0029] Such as Figure 4 , Figure 5 Shown is a schematic diagram of the structure of the cutter bar assembly of the present invention, including a base 91 sleeved outside the rotating cylinder, a cutter bar 92 fixed vertically on the base, a cutter 94 arranged at the outer end of the cutter bar, a base 91 and a rolling nut 15 through the guide key 16 fixed connection. The cutting blade 94 is connected to the tool bar 92 through a differential nut 93, and the motion is transmitted by the differential thread, which can realize accurate feeding and fine adjustment.

[0030] Such as Image 6 , Figure 7 Shown is the schematic diagram of the clutch disengaged structure of the present invention. After the clutch is disconnected online, during the movement of the entire mechanism, the flying knife assembly only moves in a circular motion without feeding, which is convenient for workers to operate and avoids parking And waste a lot of time. There is no need to stop the machine, just after the clutch is disengaged, the rotating parts and the feeding parts can be automatically separated, which saves a lot of time, improves the working efficiency of the equipment, and creates higher economic benefits.

[0031] The working process of the present invention:

[0032] The present invention is a flying knife device for electrolytic copper foil equipment. Through the frequency conversion motor and the main drive sprocket 2 through the two transmission chains 14 through the tension sprocket 3 to adjust the sprocket tightness, the power is transmitted to the feeding sprocket 4 and rotating Sprocket 5. The feed sprocket 4 drives the rolling screw 8 to move, and the rotating sprocket drives the rotating drum 12 to rotate. The rolling nut 15 can move along the axial direction of the rolling screw 8 in the rotating drum 12 under the driving of the rolling screw 8; The tool bar assembly 9 is driven to rotate and feed at the same time. The amount of cutting tool is adjusted by the differential nut 10 to complete the entire cutting process. When manual operation needs to be switched, only the clutch 6 needs to be separated from the feed sprocket 4, and then Manual operation can be achieved by turning the handwheel.
