Background technology

CN101973143A, title " changing-over materials device and pre-pressure gas channel automatically ", it comprises cylinder, the piston rod of described cylinder is connected with slide block, symmetrically, shoutoff mechanism and material receiving mechanism is installed on the slide block about two slide blocks.Shoutoff mechanism is made up of cutting knife, shock absorber and bed plate, and cutting knife is installed in slide block top and left-right symmetric, and bed plate is fixedly mounted on the integral production equipment.Material receiving mechanism is made up of big buffer substrate tablet and boost installation, and big buffer substrate tablet is fixedly mounted on the slide block and left-right symmetric.Cylinder is controlled by the precompressed air-path control system.

CN 200963916Y, title " the automatic disconnecting materials device of amenities raw MAT'L ", it comprises frame, bed plate is positioned on the frame, two cylinder fracture devices lay respectively at bed plate both sides and relative with the face of bed plate, the cylinder material-receiving device is positioned on the frame of cylinder fracture device below, and the face of the face of base and the head that connects material of cylinder material-receiving device is relative and be positioned at that material roller lays respectively at above the cylinder fracture device on the frame of cylinder fracture device below, and the guide roller is positioned at below the cylinder material-receiving device.

Number of patent application 2010105012115, title " disposable sanitary articles raw MAT'L splicing system and joining method ", raw MAT'L splicing body (1-2) both sides are respectively left uncoiling mechanism (1-1) and right uncoiling mechanism (1-2), it is characterized in that: tension force oscillating arm mechanisms (1-5) is positioned at raw MAT'L splicing body (1-2) below, splice the material warp, raw MAT'L splicing body (1-2), transition wheel (1-4) arrives the material traction wheel to tension force oscillating arm mechanisms (1-5) and by tension force oscillating arm mechanisms (1-5), and described raw MAT'L splicing body (1-2) is made up of the partial sum fracture part two parts that connect material; The part that the connects material branch left side connects material and the right connects material and two symmetrical configuration, wherein the left side connects material and is made up of a cover cylinder actuating unit and pulp-collecting box A (7), the cylinder actuating unit is linked to each other with pulp-collecting box A (7) with guide rod with two groups of linear bearings by the cylinder A (6) that connects material, link to each other by floating junction between cylinder and the pulp-collecting box, the pulp-collecting box inner hollow links to each other with the vacuum generator A of back by tracheae, and the surface of pulp-collecting box is surrounded by one deck silica gel, three row's wind inlets are arranged above, be used to hold material; The fracture part is by the two groups of left-right symmetric in the left side and the right, and wherein left side fracture is made up of a cover cylinder actuating unit and cutting knife A (2), and cutting knife divides cutter and bottom knife, cutter is used to push down material, bottom knife is used to cut off material, and cutting knife is turned right and aimed at the edge of a knife of bed plate (1), and material is cut off.

The weak point that the above-mentioned background technology exists: the one, the cutting knife in the shoutoff mechanism is subjected to the restriction of its structure, the replacing that the easily phenomenon that can't cut, and its cutting knife need be regular; The 2nd, be subjected to the restriction of splicing body, its splicing poor reliability of reloading, easily bonding obscission takes place; The 3rd, raw MAT'L thick to thickness and that fastness is good is difficult for cutting off.

The utility model content

Design goal: avoid the weak point in the background technology, design a kind of can either be effectively reliably that operating coiled material and standby coiled material is reliably bonding, again can be with the automatic crimping fracture of the amenities roll of material refueling agency of any thickness and fastness.

Design plan:, be one of technical characterictic of the present utility model for the design that realizes that above-mentioned design goal 1, left unreeling structure and right unreeling structure adopt the control of PLC controller and moved by the separately-driven left and right sides of left and right sides motor coiled material roll shaft.The purpose of doing like this is: because left unreeling structure and right unreeling structure are controlled by the instruction of PLC controller, it had both had the function of unreeling structure, had the function of rolling-up mechanism again, therefore when its during as unreeling structure, its forward rotation guarantees that coiled strip thereon permanent tension force in position unreels; When operation coiled strip diameter reaches reloading during diameter of setting, the PLC controller instructs its backward rotation, make coiled material tighten and by serrated knife tear cut off disconnected.2, the design of two cover cutting assemblies in the crimping fracture mechanism is two of technical characterictics of the present utility model.The purpose of doing like this is: be articulated and connected because the axle of serrated knife is with the cut-out cylinder piston, when the piston reset in the cut-out cylinder, driving serrated knife upwards digs, its sawtooth of upwards digging directly inserts in the material, drive the coiled material motor backward rotation that will cut off this moment, can the material that be cut is exceptionally straight, tearing cuts off; After the tearing cutting was finished, the piston that cuts off in the cylinder stretched out and serrated knife blade can be turned down, and serrated knife and material are broken away from, and made the material after reloading be in normal running state again.

Technical scheme: the automatic crimping fracture of a kind of amenities roll of material refueling agency, it comprises left unreeling structure and right unreeling structure, fracture mechanism, described left unreeling structure 1 and right unreeling structure 3 are made of the separately-driven left and right sides of left and right sides motor coiled material roll shaft, control its forward or reverse by the PLC controller respectively on the motor shaft of the left and right sides; Described fracture mechanism is by the identical and relative distribution of two cover cutting assembly structures, transition wheel in its cutting assembly is connected with outer Bai Bi top with interior swing arm by the transition wheel shaft, interior swing arm is connected with main shaft and can turns up by bearing respectively with outer Bai Bi lower end opens, reset, the serrated knife two ends are positioned on swing arm and the outer pendulum wall axle bed and are positioned at the transition wheel below, cutting off cylinder one end is enclosed within on the radius stay, the other end is by attaching parts and slitter shaft is hinged and drive serrated knife stretches out or reset, holding pad is positioned at the transition wheel top and is connected with the binder cylinder piston by top board, and the binder cylinder drives stretching out of holding pad or resets.

The utility model is compared with background technology, and the one, the fracture structure adopts to tear cuts structure, not only novel in design, unique, simple, and fracture is reliable, effective, can the tear fracture any thickness and the amenities roll of material of fastness; The 2nd, be the work material roller between lay-by material material roller and work materials material roller, be again standby material roller, the while is the reverse tension roller of fracture again; The 3rd, low cost of manufacture, easy to operate, maintenance rate is low, and is applied widely.
