[0043] The frame 120 is provided with a sliding groove 121, which is connected to the feeding drive shaft 1400.

[0044] The operating principle of this utility model is as follows: When the strip passes through the feeding auxiliary component 100, the rotational motion of the feeding auxiliary and the friction between the strip and the coating roller allow the strip to flow smoothly downwards. When the strip passes through the feeding chute cooling component 400, the feeding chute guides the strip's downward flow, and air cooling ensures smooth cutting. When the strip passes through the continuous cutter component 200, the downward movement of the strip matches the rotational up-and-down movement of the continuous cutter, achieving high-efficiency continuous cutting. The cut strip flows into the feeding sorting chute component 300. During continuous production, the strip can smoothly enter the next process through the chute. If an abnormality occurs, a cylinder can move the chute to the belt conveyor to transport it out. The innovative structure of this utility model is mainly reflected in the feeding auxiliary component 100 and the continuous cutter component 200.

[0045] The principle of the feeding auxiliary component 100 is as follows: The feeding servo motor reducer 110 drives the feeding first gear 150 to rotate via the connecting shaft 1100. The feeding first gear 150 drives the feeding second gear 180, which in turn drives the first transmission gear 160, which drives the second transmission gear 170. The second transmission gear 170 then drives the feeding transmission shaft 1400 to rotate inward. Simultaneously, the feeding second gear 180 drives another symmetrical set of first transmission gears 160, which in turn drives another symmetrical set of second transmission gears 170. The second transmission gear 170 then drives another set of feeding transmission shafts 1400 to rotate outward. The two feeding transmission shafts 1400 rotate towards the center, thus assisting the strip package to move downward from top to bottom. Spacing adjustment: By adjusting the distance between the gear levers 140, the spacing of the two feeding transmission shafts 1400 is adjusted, thereby affecting the spacing of the coating rollers 1500 and meeting the transmission requirements of different strip packages. The method of adjusting the gear lever 140 by adjusting the adjusting block 1600 is to fix one end of a bolt to the adjusting block 1600 and connect the other end to the gear lever 140. The bolt changes the distance between the gear lever 140 and the adjusting block 1600, thus affecting the spacing of other structures. To meet the above conditions, we also need to leave sufficient adjustment space for the unloading drive shaft 1400, which is the sliding groove 121. The sliding groove 121 provides sufficient space for the unloading drive shaft 1400 to adjust its position.

[0046] The principle of the continuous cutting assembly 200 includes: a servo motor reducer 211 drives the first sprocket 213 to rotate, and the first sprocket 213 drives the second sprocket 214 to rotate via a chain 215. The second sprocket 214 drives the transmission shaft 222, and the transmission shaft 222 drives the first synchronous pulleys 231 symmetrically arranged on both sides to rotate synchronously. The first synchronous pulleys 231 and the second synchronous pulleys 232 achieve synchronous rotation via a synchronous belt 233. The second synchronous pulleys 232 then drive the first eccentric shaft 250 to rotate synchronously. The first eccentric shaft 250 then drives the first gear 260, the connecting block 290, and the cutting die holder 2230 to rotate synchronously. The first gear 260 externally meshes with the second gear 280 to rotate in the opposite direction, and the bearing 240, the connecting block 290, the cutting die holder 2210, the cutting die 2220, and the floating joint 2250 rotate synchronously. Because the slide rail 2110 is connected to the female die holder 2230 via the connecting block 290, and the slider 2120 is connected to the male die holder 2210, the male die 2220 and the female die 2240 perform relative linear motion on the same horizontal plane while rotating. At this time, the linear motion of the male die 2220 and the female die 2240 is a synchronous, opposite-direction shearing motion. The function of the linear slide rail and the slider is to ensure that the male die holder 2210 and the female die holder 2230 are on the same horizontal plane during eccentric rotation.

[0047] The final effect is that the cutting male die 2220 and the cutting female die 2240 achieve continuous shearing by moving closer to the whole strip during the eccentric rotation of the cutting male die 2220 and the cutting female die 2240, and then moving away and then moving closer again.

[0048] Compared with traditional technology, this utility model adds an eccentric mechanism. The eccentric mechanism is driven by gear transmission, so that the punch and die of the cutter make a circular trajectory cutting motion, so as to continuously cut the strip at the same cut.

[0049] The specific embodiments of this utility model have been described above, but this utility model is not limited thereto. Various changes can be made to this utility model as long as they do not depart from its spirit.
