In the same machine, coils or sheets are generally provided for processing and production. However, in some cases, coils and sheets are used for feeding at the same time, and the conventional single feeding method cannot meet the needs and needs to be improved. Summary of the invention

[0026] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated in conjunction with specific embodiments below.

[0027] First embodiment

[0028] The material receiving platform 300 of the first embodiment includes a horizontal material receiving plate 301 that can be raised and lowered, a plurality of fixed top columns 304 of the same height, a material clamping assembly 313 and a material unloading assembly. Figure 1 , 2 As can be seen in the figure, the horizontal material receiving plate 301 is divided into 4 pieces, the two middle pieces are larger in area, the two pieces on the sides are smaller in area, and there is a linear gap between adjacent horizontal material receiving plates 301. The horizontal material receiving plate 301 is provided with through holes 305 for the top pillars 304 to pass through. There are two rows of ten top pillars 304, so the through holes 305 of the horizontal material receiving plate 301 also have two rows of 10. The horizontal material receiving plate 301 is driven up and down by multiple cylinders 306 below. Figure 1 , 2 As shown in FIG. 3 , when the cylinder 306 is fully extended, the horizontal receiving plate 301 rises to the position of receiving the coil 302, and the top column 304 is located below the horizontal receiving plate 301. Figure 1 As shown, eight limit plates 303 are provided on the horizontal material receiving plate 301 to limit the position of the coil 302 after it is pulled out. Figure 2When the air cylinder 306 in the machine is fully retracted, the horizontal receiving plate 301 will drop to a height lower than the top column 304. At this time, the ten top columns 304 pass through the through holes 305, and the operator can place the tray with the sheet material on the top columns 304. To this end, the tray (not shown) can be provided with positioning holes corresponding to the top columns 304.

[0029] In addition, if Figure 1 As shown, the material unloading assembly includes a lead screw 308, a slide 309, a vertical cylinder 310 and a horizontal frame 311. The material unloading assembly is used to absorb the cut coil 302 on the horizontal material receiving plate 301 or the sheet material in the tray placed on the top column 304, and transfer it to the next station for the next step of processing. The lead screw 308 drives the slide 309 to move linearly, and the vertical cylinder 310 is fixed on the slide 309. The output shaft of the vertical cylinder 310 is fixedly connected to the horizontal frame 311, wherein six vacuum suction heads 312 facing downward are arranged on the horizontal frame 311. When the horizontal frame 311 moves above the coil 302 on the horizontal material receiving plate 301 or above the sheet material on the tray, the horizontal frame 311 moves downward, and the vacuum suction head 312 sucks up the coil 302 or the sheet material. After the horizontal frame 311 moves upward, it moves linearly outward to complete the transfer of the coil 302 or the sheet material.

[0030] The material clamping assembly 313 is used to clamp the coil 302, pull out the coil 302 along a straight line, and place the cut coil 302 on the horizontal receiving plate 301. Figure 3 As shown, the clamping assembly 313 includes a clamping jaw 314, a horizontal lead screw 315 and a vertical cylinder 316. The horizontal lead screw 315 drives the vertical cylinder 316 and the clamping jaw 314 to move horizontally and linearly through the slide 317, and the vertical cylinder 316 is used to drive the clamping jaw 314 to move up and down. There are three clamping jaws 314, and they are fixed on the slide 317 at equal distances. Figure 1 , 2 It can be seen that the horizontal material receiving plate 301 is divided into four parts. The clamping jaws 314 can move linearly in the gap between adjacent horizontal material receiving plates 301. Figure 1 As shown, the horizontal receiving plate 301 has risen to the position of receiving the coil 302, and the vertical cylinder 316 ( Figure 3 ) drives the clamping jaw 314 to rise to a height higher than the horizontal material receiving plate 301, so that the clamping jaw 314 can easily clamp the coil 302. When the clamping jaw 314 successfully pulls out the coil 302, there is a gap between the clamping jaw 314 and the horizontal material receiving plate 301, so there will be a gap between the coil 302 and the horizontal material receiving plate 301 (see Figure 4 When the coil 302 is cut, the vertical cylinder 316 drives the clamp 314 to descend, and the horizontal lead screw 315 continues to push the clamp 314 in the direction of pulling the material until the coil 302 reaches the position limited by the limit plate 303, and the coil 302 is smoothly taken and placed on the horizontal receiving plate 301 (see Figure 1 ).

[0031] Second embodiment

[0032] The second embodiment is a metal foil processing device. Figure 1 , 4 As shown, the metal foil material processing device includes a material receiving platform 300 and a coil cutting mechanism 200 of the first embodiment. The coil cutting mechanism 200 is arranged on one side of the material receiving platform 300. In the production line, the coil cutting mechanism 200 is upstream of the material receiving platform 300. The material clamping component 313 of the material receiving platform 300 clamps the coil 302 in the coil cutting mechanism 200, pulls out the coil 302 along a straight line, and then the coil cutting mechanism 200 cuts the coil 302. Figure 1 As shown, a detection head 307 is provided between the coil cutting mechanism 200 and the material receiving platform 300. The detection head 307 is mainly used to detect the thickness of the coil 302 to avoid pulling out a double layer. Figure 4 It is shown that when the clamping jaws 314 pull the coil 302 out of the coil cutting mechanism 200, the coil 302 is higher than the horizontal pulling plate 301. After the clamping jaws 314 pull out the set length of the coil 302, the coil cutting mechanism 200 clamps the coil 302 and cuts the coil 302 to obtain the coil 302 of the set size.

[0033] like Figure 5 The figure shows an assembly stereogram of a coil cutting mechanism 200. The coil cutting mechanism 200 is provided with a base 20, on which an upper slide 201 that can move up and down is provided. The base 20 is provided with two slide rails 202, and a corresponding slide seat 203 is fixed on the back of the upper slide plate 201, and the slide seat 203 is slidably connected to the slide rails 202. The base 20 is provided with two high-precision vertical cylinders 205, and the vertical cylinders 205 are used to drive the upper slide plate 201 to slide up and down. The upper cutting knife 204 is arranged on the upper slide plate 201, and the upper part of the upper cutting knife 204 is hinged to the upper slide plate 201, and the upper cutting knife 204 can rotate up and down around the hinge. The hinge between the upper cutting knife 204 and the upper slide plate 201 is also detachable, and the lower part of the upper cutting knife 204 is detachably fixedly connected to the upper slide plate 201. Combined with Figure 6 , 7As shown, the upper slide 201 is provided with two horizontal cylinders 206, and the positions of the two horizontal cylinders 206 correspond to the two ends of the length direction of the upper cutter 204. The output shaft of the horizontal cylinder 206 is detachably connected to the upper cutter 204. When the upper slide 201 descends for cutting, the output shaft of the horizontal cylinder 206 retracts, allowing the lower part of the upper cutter 204 to move toward the horizontal cylinder 206, so that the upper cutter 204 and the lower cutter 211 can form a vertical shear. When the upper slide 201 rises, the output shaft of the horizontal cylinder 206 extends, allowing the lower part of the upper cutter 204 to move away from the horizontal cylinder 206, so that the upper cutter 204 and the lower cutter 211 are separated, reducing unnecessary friction between the upper cutter 204 and the lower cutter 211. The main function of the horizontal cylinder 206 is to control the small-angle rotation of the upper cutter 204. Therefore, the connection between the output shaft of the horizontal cylinder 206 and the upper cutter 204 should have a certain flexibility. In addition, combined with Figure 6 , 7 As shown, the upper slide plate 201 is provided with two positioning posts 207. The positioning posts 207 are provided on one side of the horizontal cylinder 206 and the axis of the positioning posts 207 is colinear with the output shaft of the horizontal cylinder 206. When the output shaft of the horizontal cylinder 206 retracts and drives the upper cutter 204 to rotate to the maximum stroke, the positioning posts 207 abut against the upper cutter 204. At this time, the upper cutter 204 descends to form a vertical shear with the lower cutter 211. Therefore, the function of the positioning posts 207 is to accurately define the position of the upper cutter 204 during cutting, avoiding the inaccuracy caused by using the horizontal cylinder 206 to directly define the position. In addition, as Figure 7 As shown, the upper slide plate 201 is provided with a long strip of support bar 208, and the cut coil passes through the support bar 208, and the positions of the two horizontal cylinders 206 correspond to the two ends of the support bar 208. The support bar 208 is also provided with a serrated guide bar 209.

[0034] A movable safety block 210 is provided on the base 20. The safety block 210 includes at least one safety position. When the safety block 210 is located at the safety position, the safety block 210 is used to prevent the upper slide plate 201 from descending. Figure 6As shown, the safety block 210 is connected to the base 20 by a rotating shaft, that is, the safety block 210 can rotate around the rotating shaft. When the safety block 210 rotates to a vertical safety position (that is, directly below one side of the upper slide 201), the upper slide 201 will abut against the safety block 210, thereby preventing the upper slide 201 from falling. When the coil needs to be pulled out manually, the safety block 210 can be used to support the upper slide 201 to prevent the upper slide 201 from accidentally falling and causing an accident, thereby improving safety. When the upper cutter head of the upper cutter 204 needs to be replaced, the safety block 210 can also be used to support the upper slide 201, and then replaced, with a better safety factor. In other embodiments, the safety block can also be horizontally translated, and a notch can also be set on one side of the upper slide, and the safety block can be pushed into the notch to serve as the safety position of the safety block.

[0035] like Figure 6 As shown, below the upper cutting knife 204 is the lower cutting knife 211. Figure 6 , 8 As shown, a removable and replaceable strip-shaped lower cutter head 212 is fixed to the lower cutter 211 by multiple screws. When the coil passes through, the coil will pass through the top surface of the lower cutter head 212. Fig. 9 As shown, the upper cutter 204 is fixed with a detachable and replaceable strip-shaped upper cutter head 215 by a plurality of screws, and the upper cutter head 215 is embedded and fixed in the lower part of the upper cutter 204. When the upper cutter 204 cooperates with the lower cutter 211 to perform vertical shearing, the blade 216 of the upper cutter head 215 moves downward along the outer side of the blade 213 of the lower cutter head 212 to complete the guillotine-style cutting.

[0036] like Fig.10 As shown, the base 20 is also provided with an upper roller 217 that can move up and down and a lower roller 218 that can rotate. The pulled coil will pass between the upper roller 217 and the lower roller 218. The upper roller 217 is synchronously driven by two downward pressure cylinders 219 to press down and clamp the coil with the lower roller 218, and the lower roller 218 is driven to rotate by the motor 220, so that the upper roller 217 and the lower roller 218 can pull the coil. After the pulled coil passes between the upper roller 217 and the lower roller 218, it will pass through Figure 8 The transition surface 214 in the middle and lower cutting blade 211 is flush with the top surface of the lower blade head 212. Figure 8 It can be seen that the transition surface 214 is close to the other side of the blade 213 of the lower blade head 212. A pressure strip 221 for pressing the coil is provided above the transition surface 214. Fig.10 , 11As shown, the pressure strip 221 is divided into two halves and fixed to a cross bar 222 at the same time, and the cross bar 222 is driven by a cylinder 223. The cylinder 223 provides a pressing force for the pressure strip 221 through the cross bar 222. When the cylinder 223 extends, the pressure strip 221 descends and presses the coil against the transition surface 214 and the top surface of the lower blade 212. The function of the pressure strip 221 is to press the coil close to the cutting edge to ensure that the cutting edge is flat.
