According to the cutter thread hooking prevention mechanism of the sock thread cutting machine, the clamping assembly and the cutter are arranged between the two bobbins, a large spring, a second motor and a steel wire are matched, a silk thread is clamped by a clamping piece, synchronous operation is conducted through a first motor, and a silk thread cutting area is tensioned. Therefore, influence on cutter cutting caused by wire loosening is avoided.

The utility model discloses a plastic bag production technical field's device that a kind of plastic bag is divided, including cutting table, cutting table upper side movably provided with mounting plate, mounting plate downside is provided with blade, cutting table upper side is penetrated and is provided with the slot of butt joint blade, two groups of mounting blocks are movably provided in fixed frame inner side, two groups of mounting blocks outside are fixedly provided with whetstone, and multiple groups of fixed cylinders are fixedly provided in fixed frame inner side, and multiple groups of fixed cylinders inside are movably inserted with movable rod, and movable rod outside end is fixedly connected in fixed cylinder outside portion in mounting block, and first spring is provided in fixed cylinder inside. The utility model is through simple mounting structure, so that cutting blade can automatically polish while being divided to plastic bag, so as to keep the sharp degree of cutting blade, avoid dull condition, so that it is more conducive to cutting plastic bag, and the practical effect is good, and it is worth existing market promotion and use.

The cutter comprises a hollow cutter handle, an inlet and outlet is formed in the position, close to the upper end, of one side of the cutter handle in a penetrating mode, sliding grooves are formed in the inner box walls of the two sides of the inlet and outlet, and one side of the upper end of the cutter handle is rotationally connected with a rotating rod through a bearing; the folding knife comprises a knife handle and a rotating disc, the rotating disc is fixedly connected with a rotating rod, the rod wall of the lower end of the rotating rod penetrates through a bearing and the side wall of the knife handle and extends into the knife handle, the lower end of the rotating rod is fixedly connected with a gear, and sliding blocks are connected into sliding grooves in a sliding mode. The folding knife has the advantages that by arranging the rotating disc, the rotating rod, the gear and the rack plate, manual rotation can be achieved when the folding knife needs to be used; therefore, the cutter can be quickly unfolded or stored to facilitate the gear, the use convenience performance of the folding cutter is improved, meanwhile, the cutter can be driven to penetrate through the interior of the through groove to be polished under the interaction of the bidirectional rack plate and the gear during use every time, and the situation that the cutter is blunt after being used for a long time is avoided; and extra time needs to be spent for polishing.

The utility model relates to the field of suture processing, and disclose a kind of barbed cutting device of knot-free suture, including cutting table, still including movable base, movably being located on the cutting table;Two cutting parts are used to cut the barb of suture;Locking part is used to lock the suture to be cut, and the locking end of the locking part can rotate;Dust suction assembly is set on the cutting table, scraping assembly is connected to the cutting part, and scraping assembly has scraping end;The scraping assembly of the utility model can synchronously solve the problem of adhering barb of cutting end, when cutting disc high-speed rotation cuts, shell is sleeved outside cutting disc blade part, and the scraping groove opened in it is closely combined with cutting disc blade part, along with cutting disc rotation, scraping groove can scrape the barb scrap adhered in blade part in real time, prevent the dullness of cutting edge caused by scrap accumulation, guarantee the sharpness and accuracy of subsequent cutting.

The utility model discloses a full-automatic efficient die-cutting machine which comprises a base, a support is arranged on the base, an electric telescopic rod is arranged at the top end of the support, a connecting plate is arranged at the telescopic end of the electric telescopic rod, a cutting knife is arranged at the bottom end of the connecting plate, and a plurality of first springs are arranged at the bottom ends of the two sides of the connecting plate.
