Detailed Description

In order to more fully understand the technical content of the present invention, the technical solution of the present invention will be further described and explained with reference to the specific embodiments.

The present embodiment is a coil cutting mechanism, and the specific structure thereof is shown in fig. 1 to 7.

Fig. 1 shows a perspective view of the assembly of the coil cutting mechanism. The coil stock cutting mechanism is provided with a base 20, and an upper sliding plate 201 capable of moving up and down is arranged 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. 2 and 3, 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. 2 and 3, 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. 3, 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. 2, 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. 2, below the upper cutter 204 is a lower cutter 211. As shown in fig. 2 and 4, a lower cutter 211 is fixed with a detachable and 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. 5, 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. 6, 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 flush with the top surface of the lower blade 212 in fig. 4. It can be seen from fig. 4 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. 6 and 7, 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.
