Abstract
An unreeling chuck of a mechanical type splitting machine is applied in a mechanical type splitting machine for printing. A housing is a cylinder with a center aperture; one end of the housing is provided with a limit shaft shoulder, and the other end of the housing is fixedly provided with an end cap; an end cap barrel is fixed on a center shaft through a bolt; the center shaft is provided in the center aperture of the housing; the cross section of the center shaft is in regular triangular prism shape, and three angles of the regular triangular prism shape are arc-shaped; three rectangle radial apertures are uniformly distributed on the wall of the housing; a rectangle preload block is embedded in every rectangle radial aperture respectively; the inner end of the preload block is an arc surface; and the outer end of the preload block is fixedly provided with a preload tooth. The effect is as following: during the unreeling process, pretightening force is large because of automatic machinery tensioning of the shaft head, and the running is stable; during the splitting process, no rotation loss phenomena of an unreeling shaft happens; and during the roll unloading process, the shaft head automatically contracts by machinery force, and the operation is simple. Down time of faults is substantially minimized, and production efficiency is raised.
Description
Technical field
The utility model relates to the printing machinery technical field, particularly the unwinding device of cutting machine or rewinding machine.Be anchor clamps on a kind of cutting machine that parent roll is fixing specifically.
Background technology
Cutting machine will carry out regular length and cuts processing putting in order volume or whole raw MAT'L, and for example plastic package material, Packaging Box, steel plate, film, leather, wood chip etc. are cut processing, all will use fixed length, Fixed width is cut control.Through cutting the finished product of acquisition, surfacing, end face are neat.Owing to all be the specification that requires according to demanding party, so client's use is reached quick requirement.Briefly, cut exactly and the half-blank coiled material is cut into the suitable finished product of width, use for next procedure according to customer requirement.
At present, cutting machine unreels the clamping mode that chuck mainly adopts the air tensioner.This mode has required pressurized air, all will carry out artificial venting or inflation before unreeling unloading, and wastes time and energy, and greatly reduces efficiency.In addition, can't control the standard pressure value, make cutting machine when operation, unreel end and occur the phenomenon that throws switch easily, cause product rejection owing to manually inflate.
The utility model content
The purpose of this utility model is: provide a kind of mechanical type cutting machine to unreel chuck, utilize cam principle promotion pretension piece outwards to slide and clamp the paper tube inwall, make chuck sturdy and durable, guarantee the normal operation of cutting machine.
The technical solution adopted in the utility model is: the mechanical type cutting machine unreels chuck, mainly is made up of center shaft, pretension tooth, end cap, shell and pretension piece, it is characterized in that: shell has centre hole for the cylinder bodily form; One end of shell has the annular stop shaft shoulder of radial protrusion, and the other end of shell is fixed with end cap; A center shaft is arranged in the shell centre hole, and an end of center shaft has center screw, and bolt passes end cap central bore center shaft one end is fixed on the end cap inner end surface.The other end of center shaft is in the outside of shell centre hole, and the cross-sectional plane of center shaft is positive triangular shape, and prismatoidal three angles are circular arc; On the wall of shell, be evenly distributed with three rectangular radial holes; In radial hole, be embedded with the square pretension piece of a block length respectively, pretension piece and shell radial hole bearing fit, the pretension piece can slide in the shell radial hole.The inner of pretension piece is an arc surface; Center shaft rotation, top, three angles circular arc of center shaft promote the pretension piece and outwards slide.Outer face at the pretension piece is fixed with pretension tooth 3.
Described pretension tooth is plate shaped, and the outer face of pretension tooth is a circular arc, and the radius of circular arc is identical with the external diameter of shell.
Summary mechanical type cutting machine unreels the using method of chuck.Consult Fig. 1.At first, parent roll is sling with overhead traveling crane, moved to two chuck midways location, parent roll two ends central aperture chuck is inserted in, and starts chuck then and holds out against, and unloads lifting rope after two ends hold out against, and prepares the start operation.Electric motor starting, the axis of traction entry into service, driving shell 6 rotates, pind down by force of inertia, center shaft 1 adds antagonistic force in fact by 7 pairs of shells of pretension piece 6, and pretension piece 7 is outwards slided, i.e. pretension tooth 3 and the interlock of paper tube inwall, when snap-in force during greater than antagonistic force, center shaft 1 beginning is rotated synchronously with shell 6.Shut down as need and to unload volume and unload paper tube, manually apply and unreel oppositely directed tractive force, the pretension tooth paper tube inwall that will come up when the gap reaches certain value, can unload lower chuck.
The beneficial effects of the utility model: the utility model mechanical type cutting machine unreels chuck, when unreeling, and the tensioning of spindle nose automation, predetermincd tension is big, and running is stable, in cutting process, the unreeling shaft phenomenon that throws switch can not occur; When unloading volume, the spindle nose automation shrinks, and is simple to operate.Simultaneously, this design is easier, wear-resistant than air tensioner mode, does not need to inflate and exit when unreeling and unloading volume, saves time, and has improved efficiency.Because all part adopts metal material, so service life is longer, maintenance is convenient, and the processing and fabricating of metal parts is simple, and cost is lower, can change at any time.Guarantee the normal operation of cutting machine, significantly reduced the downtime, improved production efficiency.
Description of drawings
Fig. 1 is that the utility model mechanical type cutting machine unreels chuck contour structures scheme drawing.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, 1-center shaft, the spacing shaft shoulder of 2-, 3-pretension tooth, 4-end cap, 5-bolt, 6-shell, 7-pretension piece.
The specific embodiment
Embodiment 1: unreeling chuck with a mechanical type cutting machine is example, and the utility model is described in further detail.
Consult Fig. 1.The utility model mechanical type cutting machine unreels chuck, mainly is made up of center shaft 1, pretension tooth 3, end cap 4, shell 6 and pretension piece 7.
A center shaft 1 is arranged in shell 6 centre holes, and an end of center shaft 1 has the center screw of M12, and it is the centre hole of 12.5mm that bolt 5 passes end cap 4 diameters, and center shaft 1 one ends are fixed on end cap 4 inner end surfaces.The other end of center shaft 1 is in the outside of shell 6 centre holes, and center shaft 1 length is 280mm.The cross-sectional plane of center shaft 1 is positive triangular shape, and prismatoidal three angles are circular arc; Being evenly distributed with three length on the wall of shell 6 is 120mm, and wide is the rectangular radial hole of 30mm; In radial hole, be embedded with the square pretension piece 7 of a block length respectively, pretension piece 7 and shell 6 radial hole bearing fits, pretension piece 7 can slide in shell 6 radial holes.The inner of pretension piece 7 is an arc surface; Center shaft 1 rotation, top, three angles circular arc of center shaft 1 promote pretension piece 7 and outwards slide.Outer face at pretension piece 7 is fixed with pretension tooth 3, with screw pretension tooth 3 is fixed on the outer face of pretension piece 7.
Described pretension tooth 3 is plate shaped, and the outer face of pretension tooth 3 is a circular arc, and the radius of circular arc is 75mm.
When center shaft 1 does not rotate, when shell 6 rotated, the thrust of pretension piece 7 acceptor center axles 1 corner angle outwards ejected, and this moment, pretension tooth 3 maximum spreading diameters were 160mm, thereby stung tight paper tube inwall, make paper tube fix and with center shaft with changeing.Satisfy cutting machine and unreel the needs that clamp paper tube.
