Description

Technical Field

[0001] This utility model relates to the field of laminating machine technology, specifically a heat transfer label protective film laminating machine. Background Technology

[0002] With the continuous development of modern industrial production, heat transfer signs are widely used in the identification, decoration, and information display of various products. To improve the durability and protective performance of the signs, a protective film is usually applied to their surface. This protective film not only prevents the sign surface from being scratched or contaminated, but also improves its resistance to ultraviolet rays and aging, extending the lifespan of the signs.

[0003] However, existing protective film laminating equipment generally has some shortcomings, making it difficult to meet the demands of fast and efficient production. Traditional protective film laminating machines typically rely on manual operation or relatively simple mechanical methods for film lamination, resulting in low production efficiency and difficulty in ensuring lamination accuracy. On high-speed, continuous production lines, the equipment often struggles to stably and accurately complete the protective film lamination work, leading to poor label lamination results, significant film waste, and uneven lamination, severely impacting production efficiency and product quality.

The output substrate released by the feeding wheel is arranged on the support pad and keeps in close contact with the support pad. The assembly pin is arranged in a vertical direction, and the reversing turntable is rotatably mounted on the assembly pin.

[0013] Based on the above technical solutions, in order to ensure that the vacuum suction cup can accurately pick up the protective film transferred from the substrate, the following technical solutions are provided.

[0014] It also includes an optical camera, and an auxiliary bracket is fixedly connected to the mounting bracket.

[0031] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-5 A heat transfer label protective film laminating machine includes a mounting bracket 1 and a film supply component and a laminating component mounted on the mounting bracket 1.

[0033] The film supply assembly includes a feeding wheel 211, a receiving wheel 212, a guide roller 22, and two sets of drive components that are poweredly connected to the feeding wheel 211 and the receiving wheel 212 respectively. The feeding wheel 211, the receiving wheel 212, and the guide roller 22 are all rotatably mounted on the mounting bracket 1. The substrate 213 fed out by the feeding wheel 211 passes around the guide roller 22 and is then wound up to the receiving wheel 212. A protective film is evenly adhered to the substrate 213.

[0034] The bonding assembly includes a reversing turntable 31, a telescopic cylinder 32, a transfer bracket 33, and a vacuum suction cup 34. The reversing turntable 31 is rotatably mounted on the mounting bracket 1. The telescopic cylinder 32 includes two sets fixedly mounted on the reversing turntable 31 and arranged in the same diameter direction. The two sets of telescopic cylinders 32 are symmetrically arranged along the axis of the reversing turntable 31. The movable ends of the two sets of telescopic cylinders 32 are fixedly connected to the transfer bracket 33. The transfer bracket 33 is equipped with a vacuum suction cup 34, which is used to pick up the protective film.

[0035] The protective film laminating machine provided in this solution is used to be installed on a frame on one side of the production line for heat transfer printing of labels, specifically on the side of the conveying equipment, to apply a covering film to the goods that have completed the heat transfer printing process of labels and are conveyed by the conveying equipment.

[0036] The mounting bracket 1 is designed with an L-shaped structure. Triangular reinforcing members A13 are welded at the bending connection of its longitudinal section 11 and transverse section 12 to ensure the structural stability of the mounting bracket 1. The film supply assembly is assembled onto the longitudinal section 11 of the mounting bracket 1 and arranged on the outside of the mounting bracket 1 to facilitate the disassembly and replacement of the feeding roller 211 and the receiving roller 212. The bonding assembly is assembled onto the transverse section 12 of the mounting bracket 1, and the axis of the reversing turntable 31 is arranged in the vertical direction.

[0037] The reversing turntable 31 rotates 180° each time, which can change the position of the two sets of transfer brackets 33 and vacuum suction cups 34 on it. In conjunction with the telescopic cylinder 32, it drives its lifting and lowering movement, so as to pick up the protective film on the substrate 213 in the film supply assembly, perform a 180° repositioning, and then attach it to the product label transmitted from the transmission equipment. During its continuous operation, it can effectively improve the protective film bonding efficiency.

[0038] To facilitate the removal of the protective film from the substrate 213, a release film is provided on the upper surface of the substrate 213, which facilitates the removal of the protective film from the substrate 213 while avoiding contamination of the bonding surface of the protective film.

[0039] A vacuum pump can also be installed on the transverse section 12 of the mounting bracket 1. The vacuum pump is connected to the vacuum suction cup 34. When working, the suction end of the vacuum suction cup 34 is evacuated, thereby stably adsorbing the protective film onto it. When the protective film is applied to the product label, the vacuum pump stops to remove the negative pressure, thereby adhering the protective film to the label. The telescopic cylinder 32 drives the vacuum suction cup 34 to move further downward, applying downward pressure to the protective film, so that it is stably adhered to the product.

[0040] To ensure the accuracy of the protective film's adhesion to the product label, a positioning mechanism can be added to the transmission equipment to accurately position the transmitted product, thereby enabling the protective film to adhere precisely to the label and effectively protect it.

[0041] To ensure that the feeding wheel 211 and the receiving wheel 212 can be stably assembled on the mounting bracket 1 and achieve power connection with the drive component, and to facilitate their disassembly and replacement, the following technical solution is provided.

[0042] The drive assembly includes a drive motor A231, a splined shaft 232, and a worm gear A233 and a worm A234 that maintain the matching combination. The splined shaft 232 is rotatably mounted on the mounting bracket 1. The feed roller 211 and the take-up roller 212 are both provided with spline grooves 214 that are nested and inserted with the splined shaft 232 at their shaft centers. The end of the splined shaft 232 is fixedly connected to a threaded post 235, and a positioning plate 236 is screwed onto the threaded post 235. The positioning plate 236 abuts against the end faces of the feed roller 211 and the take-up roller 212.

[0043] Worm gear A233 is fixed to the center of spline shaft 232, worm A234 is rotatably mounted on mounting bracket 1, and drive motor A231 is fixedly mounted on mounting bracket 1 and poweredly connected to worm A234.

[0044] The splined shaft 232 and the splined groove 214 at the shaft center of the feeding wheel 211 and the receiving wheel 212 cooperate to ensure that the feeding wheel 211 and the receiving wheel 212 are stably installed on the splined shaft 232 and driven by the splined shaft 232. The threaded column 235 and the positioning plate 236 can stably position the feeding wheel 211 and the receiving wheel 212 on the splined shaft 232.

[0045] When the drive motor A231 is running, it can stably transmit power to the worm wheel A233 through the worm A234, and drive the spline shaft 232 and the feeding wheel 211 or receiving wheel 212 mounted on it to run stably. Due to the structural characteristics of the worm A234 and the worm wheel A233, which have the characteristics of speed reduction and torque increase and one-way self-locking, the substrate 213 can be slowly and stably released continuously, so as to ensure that the vacuum suction cup 34 can accurately pick up the protective film on it.

[0046] By adjusting the speed of the drive motor A231 in the two sets of drive components, the released substrate 213 is kept in a taut position and continuously transferred from the feeding wheel 211 to the receiving wheel 212.

[0047] To ensure that the mounting bracket 1 can be stably installed on the frame of the transmission equipment, to ensure the stability of the vacuum suction cup 34 when picking up the protective film, and to ensure that the reversing turntable 31 operates stably around the vertical axis, the following technical solutions are provided.

[0048] The bottom of the mounting bracket 1 is fixedly mounted with a connecting bracket 14 in a detachable manner. The mounting bracket 1 is also fixedly connected with a support plate 15 and an assembly pin 16. The guide rollers 22 include two sets and are respectively arranged on both sides of the support plate 15. The output substrate 213 released by the feeding wheel 211 is arranged on the support plate 15 and keeps in close contact with the support plate 15. The assembly pin 16 is arranged in a vertical direction, and the reversing turntable 31 is rotatably mounted on the assembly pin 16.

[0049] The connecting bracket 14 can be fixedly connected to the transverse section 12 of the mounting bracket 1 and the frame of the transmission equipment through bolt assembly, so as to realize the stable installation of the mounting bracket 1 and the film supply assembly and bonding assembly mounted on it on one side of the transmission equipment.

[0050] The support plate 15 is arranged on the outside of the longitudinal section 11 of the mounting bracket 1, which can stably support the released substrate 213 and cooperate with the vacuum suction cup 34 to pick up the protective film. The mounting pin 16 is fixed to the transverse section 12, which can ensure that the reversing turntable 31 operates stably around the vertical direction.

[0051] To ensure that the vacuum suction cup 34 can accurately pick up the protective film transferred from the substrate 213, the following technical solution is provided.

[0052] It also includes an optical camera 4, an auxiliary bracket 17 is fixedly connected to the mounting bracket 1, the optical camera 4 is fixedly mounted on the auxiliary bracket 17 and arranged vertically downward, and the optical camera 4 and the vacuum suction cup 34 that moves to the top of the substrate 213 are arranged on the same vertical axis.

[0053] The auxiliary bracket 17 has a U-shaped structure and is welded to the longitudinal section 11 of the mounting bracket 1. A reinforcing member B18 with the same triangular shape is welded at the connection between the two to ensure the structural strength of the auxiliary bracket 17, thereby ensuring that the optical camera 4 is stably installed on it and continuously takes pictures of the area where the vacuum suction cup 34 picks up the protective film.

[0054] The optical camera 4 can capture and detect the position of the protective film and the vacuum suction cup 34. When the center of the protective film coincides with the center of the vacuum suction cup 34, it controls the two sets of drive components to stop, so as to ensure that the vacuum suction cup 34 can accurately pick up the protective film.

[0055] To ensure that the telescopic cylinder 32 can be stably installed on the reversing turntable 31 and to achieve stable vertical lifting and lowering of the transfer bracket 33, the following technical solution is provided.

[0056] Two sets of connecting lugs 311 arranged in the same diameter direction are fixedly connected to the outer edge of the reversing turntable 31. The telescopic cylinder 32 is fixedly installed on the connecting lugs 311. A vertically arranged guide post 312 is also fixedly connected to the connecting lugs 311. The transfer bracket 33 is slidably inserted with the guide post 312.

[0057] The connection of the ear seat 311 and the guide post 312 thereon ensures that the telescopic cylinder 32 is stably installed on the reversing turntable 31 and that the transfer bracket 33 can be driven by the telescopic cylinder 32 to rise and fall stably in the vertical direction.

[0058] To ensure that the reversing turntable 31 can operate stably around its own axis, the following technical solution is provided.

[0059] The bonding assembly also includes a drive motor B35 and a matching combination of a worm wheel B313 and a worm B351. The drive motor B35 is fixedly mounted on the mounting bracket 1, the worm B351 is rotatably mounted on the mounting bracket 1 and is poweredly connected to the drive motor B35, and the worm wheel B313 is fixedly connected to the axis of the reversing turntable 31.

[0060] When the drive motor B35 is working, it can drive the worm gear B351 to rotate, thereby driving the worm wheel B313 and the reversing turntable 31 to operate stably. Since the worm wheel B313 and the worm gear B351 also have the characteristics of speed reduction and torque increase and one-way self-locking, they can achieve stable operation of the reversing turntable 31. When the bonding component is performing the action of absorbing and attaching the protective film, the reversing turntable 31 will not rotate ineffectively, further improving the accuracy of protective film bonding.
