Description

Technical Field

[0001] This utility model relates to the field of labeling and laminating technology, and in particular to a labeling and laminating device. Background Technology

[0002] A label laminating device is an automated processing device used to cover the surface of labels with protective films (such as transparent films, anti-counterfeiting films, etc.). Its core function is to tightly bond the film layer with the label substrate through processes such as heating and pressurization to enhance the durability, water resistance, anti-counterfeiting, or aesthetics of the label.

[0003] Traditional label and film installation methods typically require manual fixing, which is complex and time-consuming, impacting production efficiency. During the heating process, temperature control is not precise enough, easily leading to excessively high temperatures of the labels and films, causing material damage or deformation. Furthermore, after lamination, the high temperature of the labels and films, combined with the straight-path heat dissipation method, can easily cause heat accumulation, affecting the quality of the laminated labels and films. In addition, with traditional winding equipment, the labels and films tend to stick to the winding roller after winding, making them difficult to separate and further reducing production efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a labeling and laminating device to address the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A labeling and laminating device, comprising: The laminating equipment body has long plates connected to both sides, a rolling assembly on the top of the laminating equipment body, and two sets of heating rollers installed on the front of the laminating equipment body. A winding assembly is disposed in the center of the front side of the laminating equipment body for winding up the laminated label.

[0006] In a preferred embodiment of the labeling and laminating equipment provided by this utility model, the rolling assembly includes two circular plates, the bottom end of which is connected to the top end of a long plate, and a cylinder is connected to the center of the front side of the circular plates.

[0007] In a preferred embodiment of the labeling and laminating equipment provided by this utility model, a threaded plate is fixedly connected to one end of the cylinder, and a baffle is provided on one side of the cylinder.

[0008] In a preferred embodiment of the labeling and laminating equipment provided by this utility model, a threaded hole is provided in the middle of the baffle, and the inner wall of the threaded hole is threadedly connected to the outer wall of the threaded plate.

[0009] In a preferred embodiment of the labeling and laminating equipment provided by this utility model, a guide rod is provided on one side of the circular plate, one end of the guide rod is rotatably connected to the front of the laminating equipment body, and a limit ring is connected to one end of the guide rod.

[0010] In a preferred embodiment of the labeling and laminating equipment provided by this utility model, a round rod is provided at the bottom of the guide roller, and a round bar is provided on one side of the round rod.

[0011] In a preferred embodiment of the labeling and laminating equipment provided by this utility model, one end of both the round rod and the round roller are rotatably connected to the front side of the laminating equipment body.

[0012] In a preferred embodiment of the labeling and laminating equipment provided by this utility model, a heat-conducting cylinder is sleeved on the outside of the heating roller to conduct temperature and assist the labeling in lamination.

[0013] In a preferred embodiment of the labeling and laminating equipment provided by this utility model, the winding assembly includes a winding roller, one end of which is mounted on the front side of the laminating equipment body.

[0014] In a preferred embodiment of the labeling and laminating equipment provided by this utility model, a placement hole is provided in the middle of the winding roller, and an air suction device is installed inside the placement hole, specifically a fan.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This utility model provides a labeling and laminating device that enables rapid installation and replacement of labels and films through the cooperation of threaded holes and threaded plates, improving the adaptability and operational efficiency of the equipment. The heat-conducting cylinder, in conjunction with the self-temperature-controlled heating roller, indirectly transfers heat, ensuring the required temperature for lamination while avoiding high-temperature damage to the material. The two sets of heating rollers are arranged in an inverted triangular gradient to achieve step-by-step pressure lamination. The serpentine heat dissipation channel formed by the round rod and the round roller shortens the material cooling time and effectively avoids the heat accumulation problem caused by straight paths, resulting in better labeling and lamination effects.

[0016] This utility model provides a label coating device. The air suction device realizes intelligent adjustment of the winding tension of the coated label. The device body controls the automatic release of constraints after winding, improving winding efficiency. Based on the elastic memory characteristics of the material, a non-adhesive winding scheme is adopted to ensure that there is no residue when the material is separated, achieving more efficient winding and peeling, and allowing the rolled label to be removed more quickly.

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A labeling and laminating device includes a laminating device body 1, with long plates 2 connected to both sides of the laminating device body 1. A rolling assembly 3 is provided on the top of the laminating device body 1, and two sets of heating rollers 5 are installed on the front side of the laminating device body 1. The rolling assembly 3 includes two circular plates 31, the bottom end of which is connected to the top end of the long plates 2. A cylinder 32 is connected to the middle of the front side of the circular plates 31. A threaded plate 33 is fixedly connected to one end of the cylinder 32, and a baffle 34 is provided on one side of the cylinder 32. A threaded hole 39 is opened in the middle of the baffle 34, and the inner wall of the threaded hole 39 is threadedly connected to the outer wall of the threaded plate 33. A guide roller 35 is provided on one side of the circular plate 31, one end of which is rotatably connected to the front side of the laminating device body 1, and a limit ring 36 is connected to one end of the guide roller 35. A circular rod 38 is provided at the bottom of the guide roller 35, and a circular rod 37 is provided on one side of the circular rod 38. One end of both the round rod 37 and the round roller 38 is rotatably connected to the front of the coating equipment body 1. A heat-conducting cylinder 6 is sleeved on the outside of the heating roller 5 to conduct temperature and assist the label in coating.

[0022] It is worth mentioning that the rolled labels and films are respectively installed in the middle of the two cylinders 32. By rotating the baffle 34, the threaded hole 39 is threadedly connected to the outer wall of the threaded plate 33, thus fixing the labels and films in the middle of the cylinders 32 for subsequent lamination. The labels and films are then passed sequentially between two guide rollers 35, which are formed at the bottom of the labels and films to guide them. Subsequently, the labels and films are passed between multiple heating rollers 5. The heating rollers 5 heat the labels and films, and the temperature is conducted to the labels and films through the heat-conducting cylinder 6. The heat-conducting cylinder 6 conducts the temperature to heat the labels and films while preventing the labels and films from being damaged due to excessive temperature. The gap between the two sets of heating rollers 5 gradually decreases from top to bottom, forming an inverted triangle, which squeezes the label and film, so that the film covers the surface of the label, completing the film coating. After film coating, the label wraps around the top of the round rod 37, then around the bottom of the round roller 38, and finally is wound up by the winding assembly 4. The round rod 37 is located on the right side of the top of the round roller 38. After film coating, the label travels a longer distance in the effective space between the round rod 37 and the round roller 38, increasing the heat dissipation time and preventing the labels from sticking together due to excessive temperature after film coating.

[0023] Preferably, the device further includes a winding assembly 4, which is disposed in the center of the front side of the laminating device body 1 for winding up the laminated label. The winding assembly 4 includes a winding roller 41, one end of which is mounted on the front side of the laminating device body 1. A placement hole 42 is provided in the center of the winding roller 41, and an air suction device 43, specifically a fan, is installed inside the placement hole 42.

[0024] With the above structural design, one end of the laminated label is wrapped around the surface of the take-up roller 41. The laminating equipment body 1 controls the opening and closing of the suction device 43. When the suction device 43 is activated, it can adsorb the end of the label, causing the end of the laminated label to slightly retract into the placement hole 42. Then, by controlling the rotation of the take-up roller 41, the laminating equipment body 1 can roll up the post-laminated label. After one turn of winding, one end of the label is pressed. At this time, the laminating equipment body 1 will close the suction device 43. The end of the label will no longer retract into the placement hole 42, but will spring back to the outer wall of the take-up roller 41. After winding, there is no hard adhesion to the inner wall of the label. The laminated label can be removed from the surface of the take-up roller 41 simply by pulling the rolled label outward.
