Description

Technical Field

[0001] This utility model relates to the field of label processing technology, specifically to an integrated lamination and die-cutting device for self-adhesive labels. Background Technology

[0002] Self-adhesive labels typically require lamination and die-cutting during production to improve their durability and aesthetics. In traditional processes, lamination and die-cutting are usually two separate steps performed by different equipment, resulting in low production efficiency, cumbersome operation, and the potential for repeated handling to affect label quality. Furthermore, the positioning accuracy and lamination adhesion of existing equipment still have room for improvement, and deviations or material waste are prone to occur during die-cutting. Utility Model Content

[0003] The purpose of this utility model is to provide a reasonably designed and easy-to-use integrated lamination and die-cutting equipment for self-adhesive labels, which can effectively solve the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: It includes a workbench, support legs, a mounting frame, a positioning plate, and conveyor rollers. Support legs are fixed at the four corners of the lower surface of the workbench. A mounting frame is fixed to the upper side of the workbench, and the mounting frame is arranged in an inverted "U" shape. A positioning plate is provided on the lower side of the vertical plate on the front side of the mounting frame. The positioning plate is fixed to the front side of the upper surface of the workbench. Conveyor rollers are equidistantly screwed onto the upper sides of the positioning plate, the rear vertical plate of the mounting frame, and the front and rear vertical plates of the mounting frame via bearings. It also includes: two mounting rollers, which are respectively screwed onto the outer top wall of the mounting frame and one side wall of the workbench via support plates. An abutment mechanism is provided inside the mounting rollers. Several extrusion rollers are also included. The components are arranged in pairs, symmetrically positioned and mutually opposing each other. Several extrusion rollers on the lower side are screwed onto one side of the workbench surface via support plates. Several extrusion rollers on the upper side are screwed onto connecting frames via shafts. The connecting frames are arranged in an inverted "U" shape. Several opposing springs are equidistantly embedded and fixed on the horizontal plate of the connecting frame. The upper ends of the opposing springs are all fixed to a fixed plate. The fixed plate is fixed to the horizontal plate on the upper side of the mounting frame. There are two support plates, which are symmetrically fixed to the middle side of the side wall of the fixed plate. The support plates are fixed to the workbench. A die-cutting blade is set between the two support plates. The die-cutting blade slides in a groove on the lower surface of the mounting plate via a sliding strip. Electric push rods are symmetrically fixed to the mounting plate and connected to the upper fixed plate. The above technical solution involves placing the label and the film onto two mounting rollers, which are then pressed together by an abutting mechanism. The label and the film then pass through the corresponding upper and lower conveying rollers and extrusion rollers. During this process, an electric push rod is activated, which moves the mounting plate downwards. The mounting plate then moves the die-cutting blade downwards, thus enabling the die-cutting of the label.

[0005] As a further improvement of this utility model, the inner part of the abutting spring is provided with a guide rod. The lower end of the guide rod is embedded and fixed in the top wall of the connecting frame. The upper end of the guide rod moves through the fixing plate and is fixed with a limit plate. The limit plate and the fixing plate are set to abut against each other. The above technical solution can support the contact spring with a guide rod and limit the movement with a limiting plate to prevent the connecting frame from falling downwards.

[0006] As a further improvement of this utility model, the abutting mechanism includes: abutting strips, wherein there are several abutting strips, which are inserted at equal angles into the annular wall of the mounting roller. The protrusions on the inner side of the abutting strips are slidably disposed in a rectangular cavity on the inner wall of the mounting roller. Several push springs are equidistantly disposed inside the abutting strips, and the other end of the push springs passes through the abutting strips and is fixed to the inner wall of the mounting roller; abutting rings, wherein there are two abutting rings, which are symmetrically sleeved at both ends of the mounting roller. Several connecting strips are provided at equal angles on the inner annular wall of the abutting rings. The front abutting ring is fixedly connected to the connecting strips by bolts, and the rear abutting ring is welded to the connecting strips. The connecting strips are movably disposed in the strip-shaped holes on the mounting roller; a bidirectional lead screw, wherein the bidirectional lead screw is screwed into the mounting roller through bearings. The front end of the bidirectional lead screw passes through the front end of the mounting roller and is exposed on the front side of the mounting roller. The nuts at both ends of the bidirectional lead screw are fixedly connected to several connecting strips on the adjacent side, respectively. The above technical solution involves loosening the front abutment ring, then placing the film-coating roll or label roll on the installation roller, pushing the spring force to push the abutment strip, thus facilitating installation. The front abutment ring is then installed onto several connecting strips on the front side. Finally, the bidirectional lead screw is rotated, and the bidirectional lead screw drives the connecting strip to move through the nut on it. The connecting strip drives the abutment ring to move until the abutment rings on both sides abut against the roll, thereby achieving the effect of limiting installation.

[0007] As a further improvement of this utility model, a guide roller is screwed onto the side wall of the mounting bracket away from the mounting plate via a shaft seat, and the guide roller is located above the side of the conveying roller. The above technical solution can guide the material on the upper side.

[0008] As a further improvement of this utility model, the upper several conveying rollers are inclined downward on the side adjacent to the extrusion roller, and the vertical plate on the front side of the mounting frame is inclined downward on the side adjacent to the extrusion roller. The above technical solution allows for inclined guidance via several tilted conveyor rollers, facilitating subsequent extrusion.

[0009] As a further improvement of this utility model, the mounting plate is provided with symmetrical abutment rods on the left and right sides of the front side wall. One end of the abutment rod abuts against the front side wall of the sliding strip on the die-cutting knife. A rotating shaft is fixed on the other end of the abutment rod. The rotating shaft is screwed into the two sides of the mounting plate through bearings. A drive rod is screwed into the upper side of the mounting plate through bearings. The two ends of the drive rod are connected to the rotating shafts on both sides through worm gear pairs. One end of the drive rod is exposed on the outside of the mounting plate. With the above technical solution, after the die-cutting blade is installed, the drive rod is rotated. The drive rod drives the rotating shafts on both sides to rotate through the worm gear pair. The rotating shafts drive the abutment rods on both sides to rotate until the abutment rods abut against the sliding strip on the die-cutting blade, thereby achieving the limiting effect and facilitating replacement.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The integrated film coating and die-cutting equipment for self-adhesive labels described in this utility model integrates film coating and die-cutting into one, with automated continuous processing, precise positioning, uniform bonding, improved efficiency and reduced waste. This utility model has the advantages of reasonable design and low manufacturing cost. Attached Figure Description

[0020] See Figure 1 , Figure 3-5 As shown, based on Embodiment 1, the abutment mechanism 7 includes: The abutment strip 7-1 consists of several abutment strips, which are inserted at equal angles into the annular wall of the mounting roller 6. The protrusions on the inner side of the abutment strip 7-1 are slidably disposed in a rectangular cavity on the inner wall of the mounting roller 6. Several push springs 7-2 are equidistantly disposed inside the abutment strip 7-1. The other end of the push spring 7-2 passes through the abutment strip 7-1 and is welded and fixed to the inner wall of the mounting roller 6.

[0021] See Figure 6 As shown, based on Embodiment 1, the mounting plate 14 has symmetrically arranged abutment rods 19 on the left and right sides of its front sidewall. One end of the abutment rod 19 abuts against the front sidewall of the sliding strip on the die-cutting blade 13. A rotating shaft 20 is welded and fixed to the other end of the abutment rod 19.
