Description
Technical field
The utility model belongs to printing packaging equipment technical field, relates to a kind of double paper in reel and cuts the cutting knife device anticipating tail length.
Background technology
The cut-off knife be equipped with in current packaging facilities, use cutting knife and cut pressure roller respectively with cylinder control swing arm execution, electrical control program aspect is following two kinds of modes:
1) prepare splicing to start, after cut-off knife large arm arrives and cuts position, new and old material volume is synchronous, and function unit provides and cuts signal, and then cambered surface detects that signal cuts pressure roller and presses down, and the second last time cambered surface detects that cut-off knife large arm is regained by the action of signal cutting knife;
2) prepare splicing to start, after cut-off knife large arm arrives and cuts position, new and old material volume is synchronous, function unit provides and cuts signal, then cut pressure roller to press down, and the action of follow procedure time delay cutting knife, wherein time expand, depends on operating speed, the new volume girth of 1.3 times, and last cut-off knife large arm has been regained and cut.
Above-mentioned two kinds of cutting means cut mode, due to reasons such as cutting structure, electrical control, operating personal customs, cause cutting material tail length inconsistent and long, tension fluctuation is large, finally affect chromatography precision, cut and be lost in more than 20 meters, very large to the waste of the auxiliary material such as material, ink.
Utility model content
The purpose of this utility model is to provide a kind of double paper in reel and cuts the cutting knife device anticipating tail length, solves existing cutting knife device and easily causes cutting material tail length inconsistent and long in use, and tension fluctuation is large, finally affects the problem of chromatography precision.
The technical scheme that the utility model adopts is, a kind of double paper in reel cuts anticipates the long cutting knife device of tail, and comprise proximity switch device and cutting knife mechanism, proximity switch is arranged on the turret mount of former machine; Cutting knife mechanism is fixed in frame; Cutting knife mechanism comprises cut-off knife large arm and is arranged on the double stroke cylinder in cut-off knife large arm.
Feature of the present utility model is also,
Wherein, cut-off knife large arm is provided with gas spring, one end of gas spring with cut large arm and be fixedly connected with, the other end with cut press-roller device and be connected, the front end cutting large arm is connected with cutting knife device.
Wherein, cut press-roller device swing arm to be fixed in cut-off knife large arm by turning cylinder.
Wherein, the junction cutting press-roller device is provided with correlation photocell eye cutting large arm.
The beneficial effects of the utility model are, a kind of double paper in reel of the present utility model cuts anticipates the long cutting knife device of tail, not by the impact of the external factors such as operating personal level, experience, under same speed, material tail length is consistent, machine speed, within the scope of 50m/min-300m/min, expects tail length 200-400mm.Existing cutting apparatus can be solved due to reasons such as cutting structure, electrical control, operating personal customs by actv., cause cutting material tail length inconsistent and long, tension fluctuation is large, finally affect chromatography precision, cut and be lost in more than 20 meters, the problem very large to the waste of the auxiliary material such as material, ink.
Accompanying drawing explanation
Fig. 1 is that double paper in reel of the present utility model cuts the integral structure schematic diagram anticipating the long cutting knife device of tail;
Fig. 2 is that double paper in reel of the present utility model cuts the structural representation anticipating cutting knife mechanism in the long cutting knife device of tail.
In figure, 1. double stroke cylinder, 2. cutting knife device, 3. gas spring, 4. cut press-roller device, 5. cut-off knife large arm, 6. correlation photocell eye, 7. proximity switch device, 8. cutting knife mechanism, 9. swing arm, 10. turning cylinder, 11. frames, 12. turret mounts.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of double paper in reel of the utility model cuts anticipates the long cutting knife device of tail, and as shown in Figure 1, comprise proximity switch device 7 and cutting knife mechanism 8, proximity switch 7 is arranged on the turret mount 12 of former machine.Proximity switch 7 respectively arranges one on A, B axle, and cam is separately installed with on A, B axle, when material axle drives, when the boss on cam contacts with proximity switch 7, proximity switch is to PLC signal, Controlling solenoid valve action, described cutting knife mechanism 8 is fixed in frame 11.
The structure of cutting knife mechanism 8 as shown in Figure 2, the double stroke cylinder 1 comprising cut-off knife large arm 5 and be arranged in cut-off knife large arm 5, cut-off knife large arm 5 is provided with gas spring 3, one end of gas spring 3 with cut large arm 5 and be fixedly connected with, the other end with cut press-roller device 4 and be connected, the front end cutting large arm is connected with cutting knife device 2.
Cut pressure roller 4 swing arm 9 to be fixed in cut-off knife large arm 5 by turning cylinder 10.
The junction cutting press-roller device 4 is provided with correlation photocell eye 6 cutting large arm 5.
The utility model is when carrying out work, its working process is, when preparing splicing, press preparation splicing button, now turret mount rotates, cut-off knife large arm 5 falls, double stroke cylinder 1 now starts the first stroke and releases, when the correlation photocell eye 6 blocked on cutting knife device rolled up by virgin material, turret mount stops, in electrical control, PLC receives signal, start virgin material volume and rotate the rotating speed reaching current linear velocity, on panel, key lamp is bright, showing now can splicing, press splicing button, electrical control program can according to current linear velocity, the calculation of parameter proximity switches such as new material-coil coil-diameter provide the time expand of signal, guarantee different linear velocity, the large air bells removing roll of coil diameter presses down some certain distance before adhesive tape, after proximity switch provides signal, PLC is to the electromagnetic valve signal of control cylinder second stroke, electromagnetic valve performs an action, cylinder second stroke is released, cut-off knife large arm swings again, in the process, when pressure roller is pressed onto on virgin material volume, cylinder continues to press down, pressure roller is squeezed and by swing arm, gas spring is shunk, film severing will be expected, cut-off knife large arm second stroke is regained, cut-off knife large arm first stroke is regained, wholely cut action and complete.
