Description

Pulp molding linkage production rotary-cut jig Technical Field The invention relates to the technical field of pulp molding processing, in particular to a pulp molding linkage production rotary-cut jig. Background The pulp molding rotary cutting process is also an important process in paper plastic packaging products, and the rotary cutting process is generally applied to round and square paper plastic products, wherein the round comprises conical shapes, cylindrical shapes and elliptic shapes, and the square comprises rectangular shapes, square shapes and irregular square shapes. The rotary cutting process generally rotates the periphery of the paper-plastic product, namely the outer surface of the paper-plastic product, the rotary cutting aims at separating the surplus edges of the paper-plastic product from the finished product, because the surplus edges of the semi-finished products which are formed and dried are connected together and the surplus edges of the finished products are separated by other procedures, the conventional rotary cutting process is to put the paper-plastic product into a jig, wrap the paper-plastic product into the rotary cutting jig, but the conventional rotary cutting jig is the paper-plastic product which is fixed in the rotary cutting jig, namely the inner side, and the rotary cutting knife rotates outwards from the inside of the paper-plastic product, so that the rotary cutting process is special and cannot be applied to mass production, because the taking is inconvenient, and the rotary cutting bench equipment and the rotary cutting jig are not provided with pressing and ejection mechanism devices, so that mass production is not realized, and only can be used for proofing and testing; A vortex sawing jig similar to the one with the patent number of CN201810445443.X comprises a bottom plate, a positioning clamp, a first positioning block, a second positioning block, a third positioning block and a positioning groove, wherein the positioning groove is arranged in the middle of the bottom plate, the first positioning block, the second positioning block and the third positioning block are arranged on the bottom plate at the periphery of the positioning groove, the second positioning block is arranged between the first positioning block and the third positioning block, a triangle is formed by connecting lines among the first positioning block, the second positioning block and the third positioning block, the positioning clamp is arranged on the second positioning block, a positioning plate is arranged on an execution end rod of the positioning clamp, the positioning plate is positioned above the positioning groove, the side edge and the bottom of the static plate are positioned through the positioning block, the side edge and the bottom are not easy to fall off when castings are sawed, safety is ensured, a laser word line device is added on a sawing machine, the sawing thickness and dimensional accuracy are ensured, a grooving groove is reserved at the bottom of the jig, sawing time is easy to clean, sawing precision is improved, manufacturing cost is reduced, and the device also can be used for carrying out rotary-cut paper products and ejecting products in the same amount.
