A cutting unit of a cutting apparatus includes a fixed flange that is disposed at an end portion of a spindle to support a cutting blade and has a plurality of first gas jetting passages on a periphery thereof for jetting gas radially along a cutting edge of the cutting blade, a detachable flange that sandwiches the cutting blade in cooperation with the fixed flange and has a plurality of second gas jetting passages on a periphery thereof for jetting gas radially along the cutting edge of the cutting blade, a cover covering the cutting blade, the fixed flange, and the detachable flange, and a vacuum unit provided to the cover and configured to suck dust scattered inside the cover.

A head of a cutting device includes a base configured to be fixed to a machine tool, a cylindrical suction nozzle integral with the base, a connector integral with the base and configured to receive a suction pipe. The suction nozzle is perforated by at least one oblong hole, for example parallel to an axis of the suction nozzle.

A cutting, crimping and stacking machine that is capable of performing automatically cutting, crimping and stacking conical cornet cone packages by itself.

A dust collection assembly for a computer numerical control (CNC) cutting machine includes an adapter configured to couple to an arm of the CNC cutting machine and a head telescopically coupled to the adapter by a plurality of nested members. The CNC cutting machine includes the arm supporting a spindle and a tool holder coupled for co-rotation with the spindle. Each of the plurality of nested members are collapsible relative to each other. The head is movable between an extended position in which the nested members are configured to surround the tool holder and a tool bit, and a retracted position in which at least some of the nested members are telescopically received in the adapter. The head defines an inlet fluidly connected to the plurality of nested members when the head is at least in the extended position. The inlet is configured to fluidly connect to a vacuum.

A high-speed cutting device includes a mounting frame, a feeding mechanism, a linear chasing-cutting mechanism, an electrode guide plate, and an acceleration driving mechanism, the acceleration driving mechanism is provided on the discharging side of the electrode guide plate, and configured to perform acceleration driving on a material tape. The acceleration driving mechanism is provided behind the linear chasing-cutting mechanism to realize the acceleration driving of the material tape.

A punching device is provided with a punching head, a vacuum apparatus, a suction flow passage, and a suction switching apparatus. The punching head includes a plurality of hollow rods that move vertically, and punching tools each having an axially extending through hole provided at each front end of the hollow rods. The vacuum apparatus serves to suck punched chips generated during the punching process of the punching head. The suction flow passage selectively communicates the through holes of the punching tools with the vacuum apparatus. The suction switching apparatus changes a path of the suction flow passage so that the suction flow passage communicates only with a hollow rod performing a punching process, among the plurality of hollow rods.

An edge trimming mechanism of an edge banding machine capable of removing scraps includes a cutting device and an air guiding cover. The cutting device includes a motor having a power outputting shaft, and a cutter mounted at an end of the power outputting shaft. The air guiding cover is hollow-shaped, installed outside the motor, and has air inlet and outlet. The power outputting shaft protrudes out of the air inlet and the cutter is at least partially located out of the air inlet. An air exhausting path is defined between the inner wall of the air guiding cover and the outer wall of the motor. Two opposite ends of the air exhausting path communicate with the air inlet and outlet respectively. By the above-described configuration of the edge trimming mechanism, it is effective in removing the scraps produced by the edge banding machine in the edge trimming process.

The slitter-scorer machine includes a suction unit for removing trims cut by the cutting blades. The suction unit in turn includes a first pair of suction nozzles associated with a first set of cutting tools, and a second pair of suction nozzles, associated with a second set of cutting tools. The first pair of suction nozzles is adapted to suck trims generated by the first set of cutting tools and the second pair of suction nozzles is adapted to suck trims generated by the second set of cutting tools.

Systems and methods for cutting and cooking a substance are disclosed. Exemplary implementations may: convey, via a primary conveying subsystem, a layer of food substance along a conveyance path along which the layer of food substance is conveyed; cut, via a cutter, the layer of food substance into food pieces; apply, via a primary pressurized fluid outlet, primary pressurized fluid such that the food pieces are released from the cutter; heat, via the heating mechanism, a chamber; apply, via a secondary pressurized fluid outlet, secondary pressurized fluid so that the food pieces are held flat to the primary conveying substrate, and hold, via a secondary conveying subsystem, the layer of food substance flat between the primary conveying substrate and a secondary conveying substrate for at least a portion of the chamber.

Disclosed is a method for transferring cut-out nonwoven material members, the method including feeding a continuous web of a nonwoven material towards cutter and anvil roll, passing the continuous web between the cutter and anvil roll, the cutter roll having knives protruding from the circumferential surface, the knives having an edge with a first outline shape seen in a circumferential direction of the cutter roll, cutting the continuous web thereby forming cut-out nonwoven material members having a second outline shape corresponding to the first outline shape of the respective edge of the knives, and transferring the cut-out members to a vacuum roll having an outer circumferential surface that includes a plurality of vacuum ports arranged in a pattern, the pattern including pattern units each having a third outline shape, the pattern units fitting within the second outline shape of the cut-out members.
