Description

Technical Field

[0001] The invention relates to the field of Inlay composite, and in particular to an Inlay composite flat-plate die-cutting machine. Background Art

[0002] Inlay is a special term in the smart card industry, which refers to a pre-laminated product composed of multiple layers of PVC sheets containing chips and coils. It is generally composed of two or three layers. There is no printed pattern on the surface. INLAY products are suitable for the early mass production of multiple varieties of cards. INLAY is covered with materials with different printed patterns on the top and bottom, and then laminated again to form a colorful contactless card.

[0003] At present, in the process of Inlay processing, the Inlay label is compounded with the surface material and the base material. For example, in the patent CN106599978A, a production device of an inlay electronic label is mentioned, including a touch switch, an inlay coil feed roller, a deviation corrector, a self-adhesive label feed roller, an auxiliary material feed roller, a compound mechanism, a first receiving roller, a compound die-cutting mechanism, a second receiving roller, a finished product receiving roller and a synchronous controller, a first color mark sensor, a second color mark sensor, and a pressing mechanism is provided in the compound mechanism, and the pressing mechanism includes a clamping upper wheel and a clamping lower wheel provided with a soft and wear-resistant rubber layer. The present invention also provides a production method of the above-mentioned inlay electronic label. The production device of the inlay electronic label of this structure has a coil anti-shake function, which improves the stability of the whole machine; at the same time, through the vacuum adsorption type winding / waste discharge structure, the winding and unwinding are ensured to be stable and the speed is increased; in addition, the production device is also provided with 3 sets of color mark sensor fine-tuning mechanisms, which can realize convenient paper material deviation correction and alignment adjustment and improve the machine adjustment speed.

[0004] The above-mentioned inlay electronic label production device still has certain defects during the production process: when the inlay is die-cut, it is realized by the cooperation of components such as a rotary knife, a flat knife, and a vacuum drum. When the rotary knife rotates, it cooperates with the flat knife to realize the equidistant cutting of the inlay. The structure of the existing rotary knife is usually to attach a layer of die-cutting tool to the circumferential surface of the circular shaft, and then the equidistant cutting of the inlay label is realized by the rotation of the circular shaft. In such a cutting method, the cutting distance of the inlay label is affected by the size of the die-cutting tool, that is, a die-cutting tool of one size can only realize the cutting of inlay labels of one specification. When it is necessary to cut inlay labels of different specifications, it is necessary to attach die-cutting tools of different sizes on the circular shaft for cooperation. The versatility is not strong, and the cost of such die-cutting tools is relatively high. Therefore, when the specifications of the inlay labels to be produced are more, die-cutting tools of multiple specifications are required, and the cost is also relatively high.

[0035] For the design of Inlay label composite unit;

[0036] The surface material unwinding mechanism and the bottom material unwinding mechanism are designed, and the first Inlay guide roller, the second Inlay guide roller, the first bottom material guide roller, the second bottom material guide roller, and the surface material guide roller are matched with different winding methods.

Since Inlay is a relatively precise electronic label, a single-layer Inlay is relatively fragile. This correction method is used to avoid direct forced correction of the single-layer Inlay material tape, which may damage the Inlay and cause the Inlay to be scrapped.

[0040] For a pair of cylindrical roller bearings arranged between the Inlay unwinding shaft and the movable deviation correcting seat, the cylindrical rollers in the two cylindrical roller bearings are arranged tilted, and the tilt directions of the cylindrical rollers of the two cylindrical roller bearings are opposite, so as to ensure the stable and smooth rotation of the Inlay unwinding shaft and avoid jamming.

[0041] The deviation correction detection sensor installed at the outlet of the Inlay unwinding roller detects the position of the Inlay material roll, providing a basis for the subsequent automatic deviation correction of the Inlay material roll.

[0042] For the design of buffer unit:

[0043] The buffer roller adopts a design of a stepped buffer drum and a stepped buffer shaft, and cooperates with a first bearing and a second bearing, so that the buffer drum can rotate smoothly to avoid the buffer drum from getting stuck. In addition, two guide limit rings arranged on the outer surface of the buffer drum are used to guide and limit the passing material belt to avoid deviation.

[0044] The detection plate is used in conjunction with several photoelectric detection switches to detect the upper and lower positions of the buffer roller to ensure the position of the buffer roller, thereby providing a basis for the subsequent automatic control of the rotation speed of the unwinding roller and the receiving roller.

[0045] For the design of flatbed die-cutting unit:

[0046] The feed guide rod is set to guide the material strip when it enters the flat die-cutting unit; and for the installation of the feed guide rod, the waist-shaped adjustment hole set on the feed guide bracket cooperates with the adjusting bolt, so that the upper and lower positions of the feed guide rod can be fine-tuned to facilitate the guiding of the material strip; and the limit ring on the feed guide rod is designed to guide and limit the passing material strip to avoid deviation, and the limit ring and the feed guide rod are locked and fixed with a tightening nut, so that the relative movement of the limit ring and the feed guide rod can be realized, so that adjustment can be made according to material strips of different widths.

[0047] For the setting of the rubber-coated roller and the paper-pulling roller, the rectangular adjustment hole, the T-shaped mounting block, the adjustment screw and the spring are used to cooperate with each other, so that the rubber-coated roller can be adjusted up and down, so as to adjust the relative position between the rubber-coated roller and the paper-pulling roller according to the material belt of different thicknesses.

[0054] The following embodiments can enable those skilled in the art to more fully understand the present invention, but the present invention is not limited to the scope of the embodiments.

[0056] A pair of Inlay label compounding units and a flat plate die-cutting unit are arranged in parallel, and a buffer unit is arranged between the Inlay label compounding unit and the flat plate die-cutting unit.

[0057] The inlay label compounding unit comprises a compound frame 1, on which an inlay unwinding assembly, a substrate unwinding assembly, and a compound traction assembly are installed. The inlay unwinding assembly comprises an inlay unwinding roller 21 and an inlay waste collecting roller 22, and the inlay unwinding roller 21 and the inlay waste collecting roller 22 are arranged in parallel on the compound frame 1 from top to bottom.

[0058] like Figure 2 As shown in the schematic diagram, a deviation correction component is also arranged between the Inlay unwinding roller 21 and the composite frame 1. The deviation correction component is as follows: the Inlay unwinding roller includes an Inlay unwinding shaft 201, one side of the Inlay unwinding shaft 201 horizontally extends into the composite frame 1, a through hole for the Inlay unwinding shaft 201 to pass through is opened on the side wall of the composite frame 1, and a pair of Inlay positioning seats 202 are also mounted on the side of the Inlay unwinding shaft 201 located outside the composite frame 1. The Inlay positioning seats 202 are truncated cone-shaped, and the sides with smaller diameters of the two Inlay positioning seats 202 are arranged opposite to each other, and a gap for the Inlay material roll to be mounted is left between the two Inlay positioning seats 202. For the Inlay unwinding roller 21, the Inlay unwinding shaft 201 and the Inlay positioning seat 202 are matched, so that when the Inlay material roll is mounted on the Inlay unwinding roller 21, the relative position between the Inlay material roll and the Inlay unwinding roller can be limited and fixed.

[0059] A deflection correction seat and a driver 203 are installed in the composite frame 1. The deflection correction seat includes a fixed deflection correction seat 204 and a movable deflection correction seat 205. The fixed deflection correction seat 204 is fixed on the inner wall of the composite frame Inlay positioning seat 202. A through hole is provided in the fixed deflection correction seat 204 for the movable deflection correction seat 205 to pass through and move. A linear guide is provided between the movable deflection correction seat 205 and the fixed deflection correction seat 204. The end of the direct line shaft 206 is fixed to the end of the fixed deflection correction seat 204 by screws. A through hole is provided in the movable deflection correction seat 205 for the Inlay unwinding shaft 201 to pass through.

[0060] A cylindrical roller bearing 207 is also arranged between the Inlay unwinding shaft 201 and the movable deviation correcting seat 205. The cylindrical roller bearing 207 is located on both sides of the inner wall of the movable deviation correcting seat 205. The cylindrical rollers in the cylindrical roller bearing 207 are arranged tilted, and the tilting directions of the cylindrical rollers of the two cylindrical roller bearings 207 are opposite. The Inlay unwinding shaft 201 passes through the movable deviation correcting seat 205 and is connected to the torque speed regulating right angle motor 208. The torque speed regulating right angle motor 208 is connected to the movable deviation correcting seat 205. The movable deviation-correcting seat 205 is fixed to the end of the movable deviation-correcting seat 205 through a connecting block 209. The movable deviation-correcting seat 205 is driven by the driver 203 to perform horizontal reciprocating movement in the fixed deviation-correcting seat 204. In the embodiment, the driver 203 can be a linear driver such as an electric push rod, a hydraulic cylinder, etc. One side of the driver 203 is hinged to the inner wall of the composite frame 1, and the other side of the driver 203 is hinged with a transition plate 210, and the transition plate 210 is fixed to the end of the movable deviation-correcting seat 205.

[0061] During the deflection correction, the driver 203 drives the transition plate 210 to move horizontally, and the horizontal movement of the transition plate 210 pulls the movable deflection correction seat 205 to move back and forth along the fixed deflection correction seat 204, and the movement of the movable deflection correction seat 205 drives the Inlay unwinding shaft 201 to move horizontally, thereby driving the horizontal movement of the entire Inlay unwinding roller 21, so as to realize the horizontal deflection correction of the Inlay roll on the Inlay unwinding roller 21.

[0062] For the deflection correction component, the deflection correction seat and the driver 203 cooperate to drive the entire Inlay unwinding roller 21 to move horizontally to achieve deflection correction. Since Inlay is a relatively precise electronic label, a single-layer Inlay is relatively fragile. This deflection correction method is used to avoid direct forced deflection correction of the single-layer Inlay material strip, which may cause damage to the Inlay and lead to the scrapping of the Inlay.

[0063] A deflection correction detection sensor 23 is also provided at the discharge port of the Inlay unwinding roller 21.

[0086] The finished product receiving roller 43 is driven to rotate by a finished product receiving motor.

[0087] Working principle: When laminating the three layers of surface material, inlay and base material:

[0088] After the Inlay tape is unwound from the Inlay unwinding roller 21, it passes over the first Inlay guide roller 213 located on the upper side, the second Inlay guide roller 214, and the first Inlay guide roller 213 located on the lower side in sequence, and then enters the first traction roller 212, so that it passes between the two first traction rollers 212 and directly enters between the two second traction rollers 211 to wait for lamination;

[0089] After the surface material strip is unwound from the surface material unwinding roller 24, it passes over each surface material guide roller 223 in turn and enters between two second traction rollers 211 to wait for lamination;

[0090] After the base material strip is unwound from the base material unwinding roller 26, it is dyed from the second base material guide roller 220 and then enters between the second traction rollers 211 to wait for lamination;

[0091] When the surface material belt, the Inlay material belt and the bottom material belt all reach the two second traction rollers 211, the surface material belt, the Inlay material belt and the bottom material belt are passed through the two second traction rollers 211 from top to bottom, thereby realizing the three-layer compounding of the surface material belt, the Inlay material belt and the bottom material belt. The compounded three-layer belt enters the flat die-cutting unit, and the three-layer belt is cut equidistantly through the cooperation of the upper die plate 41 and the bottom die plate 42. The cut belt enters the rubber coating roller 404 and the paper pulling roller 405, and is rubber coated as needed. The rubber coated belt is then collected by the finished product receiving roller 43 to complete the processing.

[0092] When laminating both sides of the Inlay and substrate:

[0093] After the inlay tape is unwound from the inlay unwinding roller 21, it passes over the two first inlay guide rollers 213 and enters the label tearing assembly to prepare for label tearing and lamination;

[0094] After the bottom material strip is unwound from the bottom material unwinding roller 26, it passes over the first bottom material guide roller 219 and enters the compounding platform 28 to wait for compounding;

[0095] When both the Inlay material strip and the bottom material strip reach the composite platform 28, the Inlay material strip is first torn off, and the single Inlay label after the torn off label is composited on the bottom material strip, and then the bottom material of the composite Inlay label passes through the two second traction rollers 211, thereby realizing the two-layer composite of the Inlay label and the bottom material strip. The two-layer composited material strip enters the flat die-cutting unit, and the two-layer material strip is cut equidistantly through the cooperation of the knife die upper plate 41 and the knife die bottom plate 42. The cut material strip enters the rubber coating roller 404 and the paper pulling roller 405, and is coated with rubber as needed.
