Introduce in detail: What are the technical characteristics of intelligent cotton sticking machine-knife die cotton sticking process?

Core technical characteristics of intelligent cotton sticking machine | knife die cotton sticking process

Knife die sticking cotton (die sticking cotton) is mainly applied to laser die and wood die processing, and foam pads (gold glue, grey glue, EVA, high elastic sponge, etc.) are accurately stuck on both sides of the blade, which are used for discharging, buffering, protecting the blade and preventing material adhesion. Knife-die cotton sticking technology relies on intelligent cotton sticking machine to realize the integration of automatic cutting, material taking, gluing/hot melting and accurate sticking, which is different from traditional manual cotton sticking and simple roll sticking technology. The complete technical features are arranged as follows:

First, digital trajectory drive, direct docking of CAD drawings

Support the import of DXF die drawings, the software automatically identifies the outline of the cutter line, and generates the running path of cotton sticking with one key;

Free setting of single-sided cotton sticking, double-sided cotton sticking, local intermittent cotton sticking and corner irregular cotton sticking;

Support manual fine adjustment of cotton pasting width, offset distance and end reserved length, and adapt to different process standards of cigarette packets, color boxes, corrugated and precision electronic die cutting dies;

Distinguish between straight line segment and arc corner, automatically optimize the corner cutting scheme, and eliminate the problems of corner cotton shortage and excessive splicing gap.

Second, the cutting-pasting contract is integrated step by step, and the advantages of flexible material forming are outstanding.

Coil/plate double feeding mode

The whole board foam can be used for cutting, or the coiled material can be continuously fed and cut at a fixed length as required to reduce the scrap of raw materials; Continuous cutting of straight lines and independent punching of special-shaped segments.

One machine compatible straight bar+special-shaped bar mixed machining

Special-shaped slivers are automatically generated at corners of complex graphics and island knife lines without manual secondary cutting; Small narrow cotton strips are grabbed and attached independently.

The two bonding processes can be switched freely.

Hot-melt cotton sticking: adapt to the self-contained hot-melt adhesive foam, instantly melt and stick when heated, and cure quickly, which is not easy to shift;

Automatic glue dispensing process: for ordinary elastic cotton without back glue, precise and micro glue dispensing is carried out, and the glue is even, so as to avoid the overflow of glue from polluting the knife plate.

Third, high-precision positioning and bonding, the consistency of finished products far exceeds manual work.

Numerical control servo motion system, the position error of cotton sticking can be controlled, the cotton sliver is close to the blade and the spacing is uniform;

Constant pressure bonding mechanism, self-adaptive pressure adjustment, thin foam does not collapse, high-density hard glue is firmly bonded;

Effectively put an end to the common defects of labor: cotton sliver skew, edge warping, missing sticking, different lengths, and cotton sticking distance suddenly approaching and far away;

The whole die is stressed evenly, and the material is discharged smoothly during die cutting production, which improves the die cutting yield and prolongs the service life of the die.

Fourth, intelligent material optimization can effectively reduce the loss of raw materials.

Software intelligent typesetting, compact arrangement and cutting of multiple slivers, optimizing the utilization rate of foam;

Automatically filter tiny cotton segments that can't be grabbed, which can be subsidized manually after marking to reduce invalid cutting of materials;

Cut as required, and do not need to cut the sliver in batches in advance for stacking, so as to avoid the deformation of long foam.

Five, automatic continuous operation, the production efficiency is significantly improved.

Automation of the whole process: feeding → feeding cotton → cutting → taking materials → gluing/hot melting → aligning and laminating for cyclic operation;

High-end models support double-station parallel mode: while cutting sliver, attaching is carried out, and the working procedures overlap, which greatly shortens the processing time of large plate die;

Support the continuous processing of long-size large-plate die (large-format laser die), and adapt to the order of carton factory and large color box die;

Reduce manpower dependence, one operator can take care of multiple devices at the same time, and get rid of the shortage of skilled cotton pasting technicians.

Six, a wide range of material compatibility, covering the mainstream knife die pad.

Knife die sticking cotton technology can stably process all kinds of commonly used elastic cotton;

High elastic sponge, imported gold elastic rubber, gray elastic rubber, EVA foam, CR rubber, PORON cushioning material;

Support the switching production of foam with different thickness and hardness, and quickly change materials without complex tooling transformation.

VII. Advantages of Safety and Process Stability

Closed cutting mechanism, no need to manually hold foam near the blade, eliminating the risk of scratch and work injury;

Processing parameters can be stored in the formula, different customers and different products can call the preset program, and the order can be changed quickly;

The whole process can be traced, and the cotton pasting path and processing parameters are saved, which is convenient for standardized mass production;

The finished die can be delivered directly to the downstream die-cutting workshop, realizing the delivery of the finished die, which is different from the traditional semi-finished bare die plate.

Eight, compared with the traditional process core differences summary

Manual cotton sticking: low efficiency, large quality fluctuation, difficult recruitment, poor corner treatment and rising cost.

Simple roll-sticking: only suitable for simple long straight bars, complex special-shaped knife dies can not be processed, and the versatility is poor.

Sticking cotton technology of intelligent equipment knife die: straight line+arc special-shaped all-round processing, stable precision, standardization, suitable for complex boutique knife die (high-end color box, drug packaging, electronic accessories die-cutting knife die)

Knife-die cotton sticking technology relies on numerical control intelligent cotton sticking equipment, introduces CAD data of knife die to automatically plan cotton sticking trajectory, and completes the integrated processing of foam automatic cutting, precise grasping, constant temperature hot melting/precise dispensing and servo alignment sticking. It can realize the unified processing of straight line, arc and corner shaped sliver, with regular cotton sticking position, balanced pressure and no warping and missing sticking; Adapting to a variety of elastic foam materials, taking into account the production of large and small precision knife dies, helping knife die manufacturers to realize automatic upgrading of cotton sticking process, stabilizing the quality of knife dies, shortening delivery time and controlling production costs.
