Detailed Description

In order to more fully understand the technical contents of the present invention, the technical solutions of the present invention will be further described and illustrated with reference to the following specific embodiments.

First embodiment

The receiving platform 300 of the first embodiment includes a horizontal receiving plate 301 capable of ascending and descending, a plurality of fixed top pillars 304 with the same height, a material clamping assembly 313 and a blanking assembly. As can be seen from fig. 1 and 2, the horizontal material receiving plates 301 are divided into 4 pieces, the areas of the two middle pieces are larger, the areas of the two side pieces are smaller, and a linear gap is left between the adjacent horizontal material receiving plates 301. The horizontal material receiving plate 301 is provided with a through hole 305 through which the top pillar 304 passes. There are two rows of ten top columns 304, and thus there are two rows of 10 through holes 305 of the horizontal material receiving plate 301. The horizontal material receiving plate 301 is driven to move up and down by a plurality of cylinders 306 below. As shown in fig. 1 and 2, when the cylinder 306 is fully extended, the horizontal receiving plate 301 is raised to the position of the receiving coil 302, and the top pillar 304 is located below the horizontal receiving plate 301. As shown in fig. 1, the horizontal receiving plate 301 is provided with 8 stopper plates 303 for restricting the position of the coil 302 after being pulled out. When the cylinder 306 in fig. 2 is fully retracted, the horizontal material receiving plate 301 is lowered to a level lower than the top pillars 304, and ten top pillars 304 are inserted through the through holes 305, so that the operator can place the tray on which the material is placed on the top pillars 304 and fix the tray. To this end, the tray (not shown) may be provided with positioning holes corresponding one-to-one to the top posts 304.

Further, as shown in fig. 1, the blanking assembly includes a lead screw 308, a slide 309, a vertical cylinder 310, and a horizontal frame 311. The blanking assembly is used for sucking cut rolls 302 on the horizontal material receiving plate 301 or sheets in a tray placed on the top column 304, and transferring the cut rolls or sheets to the next station for further processing. The lead screw 308 drives the slide 309 to move linearly, and the vertical cylinder 310 is fixed to the slide 309. The output shaft of the vertical cylinder 310 is fixedly connected with a horizontal frame 311, wherein 6 downward vacuum suction heads 312 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 on the tray, the horizontal frame 311 moves downwards, the vacuum suction head 312 sucks up the coil 302 or the sheet, and the horizontal frame 311 moves outwards in a straight line after moving upwards, so that the transfer of the coil 302 or the sheet is completed.

The material clamping assembly 313 is used for clamping the roll material 302, pulling out the roll material 302 along a straight line and placing the cut roll material 302 on the horizontal material receiving plate 301. As shown in fig. 3, 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 sliding plate 317, and the vertical cylinder 316 is used for driving the clamping jaw 314 to move up and down. The clamping jaws 314 are three in number and are equidistantly fixed to the slide 317. As can be seen from fig. 1 and 2, the horizontal material receiving plate 301 is divided into four pieces. The jaws 314 are linearly movable in the gaps between adjacent horizontal receiver plates 301. As shown in FIG. 1, the horizontal material receiving plate 301 has been raised to the position of the material 302, and the vertical cylinder 316 (FIG. 3) drives the clamping jaws 314 to rise to a height higher than the horizontal material receiving plate 301, so that the clamping jaws 314 can clamp the material 302. When the clamping jaws 314 are pulled out of the coil 302 smoothly, there is a gap between the clamping jaws 314 and the horizontal receiving plate 301, so that a gap is left between the coil 302 and the horizontal receiving plate 301 (see fig. 4). After the coil 302 is cut, the vertical cylinder 316 drives the clamping jaws 314 to descend, and the horizontal lead screw 315 continues to push the clamping jaws 314 to advance in the material pulling direction until the coil 302 reaches the position defined by the limiting plate 303, so that the coil 302 is smoothly taken and placed on the horizontal material receiving plate 301 (see fig. 1).

Second embodiment

The second embodiment is a metal foil processing apparatus. As shown in fig. 1 and 4, the metal foil processing apparatus includes a receiving platform 300 and a roll cutting mechanism 200 according to the first embodiment. The coil cutting mechanism 200 is arranged on one side of the receiving platform 300. In the production line, the coil cutting mechanism 200 is upstream of the receiving platform 300. The material clamping assembly 313 of the receiving platform 300 clamps the roll material 302 in the roll material cutting mechanism 200, pulls out the roll material 302 in a straight line, and then cuts the roll material 302 by the roll material cutting mechanism 200. As shown in fig. 1, a detecting head 307 is disposed between the receiving platform 300 and the coil cutting mechanism 200, and the detecting head 307 is mainly used for detecting the thickness of the coil 302 to avoid pulling out a double layer. Fig. 4 shows the web 302 at a higher elevation than the horizontal draw plate 301 when the jaws 314 are pulling the web 302 from the web cutting mechanism 200. After the jaws 314 are pulled out of the set length of the roll 302, the roll cutting mechanism 200 grips the roll 302 and cuts the roll 302 to obtain a set size of the roll 302.

Fig. 5 is an assembled perspective view of the web cutting mechanism 200. The coil cutting mechanism 200 is provided with a base 20, and an upper slide plate 201 which can move up and down is provided on the base 20. The base 20 is provided with two slide rails 202, the back of the upper slide plate 201 is fixed with a corresponding slide seat 203, and the slide seat 203 is connected with the slide rails 202 in a sliding manner. The base 20 is provided with 2 high-precision vertical cylinders 205, and the vertical cylinders 205 are used for driving the upper sliding plate 201 to slide up and down. The upper cutter 204 is arranged on the upper sliding plate 201, the upper part of the upper cutter 204 is hinged with the upper sliding plate 201, and the upper cutter 204 can rotate up and down around the hinged part. The upper cutter 204 is also detachably hinged to the upper sliding plate 201, and the lower part of the upper cutter 204 is detachably fixed to the upper sliding plate 201. As shown in fig. 6 and 7, the upper sliding plate 201 is provided with two horizontal cylinders 206, and the two horizontal cylinders 206 are located at positions corresponding to two ends of the upper cutter 204 in the length direction. The output shaft of the horizontal cylinder 206 is detachably connected with the upper cutter 204. When the upper sliding plate 201 descends to cut, the output shaft of the horizontal cylinder 206 retracts, and the lower part of the upper cutter 204 moves towards the horizontal cylinder 206, so that the upper cutter 204 and the lower cutter 211 can form vertical cutting. When the upper sliding plate 201 ascends, the output shaft of the horizontal cylinder 206 extends to make the lower part of the upper cutter 204 move back to the horizontal cylinder 206, so that the upper cutter 204 is separated from the lower cutter 211, and unnecessary friction between the upper cutter 204 and the lower cutter 211 is reduced. The horizontal cylinder 206 mainly controls the small angle rotation of the upper cutter 204, so the connection between the output shaft of the horizontal cylinder 206 and the upper cutter 204 should have a certain flexibility. In addition, as shown in fig. 6 and 7, the upper sliding plate 201 is provided with two positioning posts 207. The positioning column 207 is provided on the side of the horizontal cylinder 206 and the axis of the positioning column 207 is collinear with the output shaft of the horizontal cylinder 206. When the output shaft of the horizontal cylinder 206 retracts to drive the upper cutter 204 to rotate to the maximum stroke, the positioning column 207 abuts against the upper cutter 204, and at the moment, the upper cutter 204 descends to vertically cut the lower cutter 211. Therefore, the positioning post 207 is used for accurately defining the position of the upper cutter 204 during cutting operation, and avoiding the inaccuracy caused by directly defining the position by using the horizontal air cylinder 206. In addition, as shown in fig. 7, the upper sliding plate 201 is provided with a strip-shaped supporting strip 208, the cut roll material passes through the supporting strip 208, and the two horizontal air cylinders 206 are arranged at the two ends of the supporting strip 208. The supporting strip 208 is also provided with a saw-toothed conducting strip 209.

The base 20 is provided with a removable safety block 210. 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 block the upper slide plate 201 from descending. In the present embodiment, as shown in fig. 6, the safety block 210 is connected to the base 20 as 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 (i.e. directly under one side of the upper sliding plate 201), the upper sliding plate 201 and the safety block 210 will abut against each other, so that the upper sliding plate 201 cannot fall down. When the coil stock needs to be pulled out manually, the safety block 210 can be used for supporting the upper sliding plate 201, accidents caused by accidental falling of the upper sliding plate 201 are avoided, and the safety is improved. When the upper cutter head of the upper cutter 204 needs to be replaced, the safety block 210 can be used for propping against the upper sliding plate 201 and then replacing the upper sliding plate, so that the safety coefficient is better. In other embodiments, the safety block can also be transversely translated, and a notch can be arranged on one side of the upper slide plate, so that the safety block can be pushed into the notch to serve as a safety position of the safety block.

As shown in fig. 6, below the upper cutter 204 is a lower cutter 211. As shown in fig. 6 and 8, a lower cutter 211 is detachably fixed with a replaceable elongated lower cutter head 212 by a plurality of screws. As the web passes, it passes over the top surface of the lower blade 212. As shown in fig. 9, the upper cutter 204 is fixed with a detachable and replaceable elongated upper cutter head 215 by a plurality of screws, and the upper cutter head 215 is inserted and fixed in a lower portion of the upper cutter 204. When the upper cutter 204 cooperates with the lower cutter 211 for vertical cutting, the cutting edge 216 of the upper blade 215 moves downward against the outer side of the cutting edge 213 of the lower blade 212, thereby completing guillotine-type cutting.

As shown in fig. 10, the base 20 is further provided with an upper roller 217 which can move up and down and a lower roller 218 which can rotate. The drawn-out web passes between the upper and

lower rollers

217 and 218. The upper roller 217 is driven by two lower pressing cylinders 219 to press and clamp the roll with the lower roller 218 synchronously, and the lower roller 218 is driven by a motor 220 to rotate, so that the upper roller 217 and the lower roller 218 can pull the roll. After passing between the upper and

lower rolls

217 and 218, the drawn web passes through a transition surface 214 of the lower cutter 211 in fig. 8, which is flush with the top surface of the lower blade 212. It can be seen from figure 8 that the transition surface 214 abuts the opposite side of the cutting edge 213 of the lower cutting insert 212. Above the transition surface 214, a pressing strip 221 for pressing the web is provided. As shown in fig. 10 and 11, the pressing bar 221 is divided into two halves and fixed to a cross bar 222, and the cross bar 222 is driven by a cylinder 223. The air cylinder 223 provides a pressing force to the pressing bar 221 through the cross bar 222. When the cylinder 223 extends, the bead 221 descends and presses the web against the transition surface 214 and the top surface of the lower blade 212. The pressing strip 221 is used for pressing the roll material at the position close to the cutting opening so as to ensure that the cutting opening is smooth.
