Description

Technical Field

[0001] This utility model relates to the field of film application device technology, specifically a device for applying decorative film to the surface of a lid. Background Technology

[0002] A bottle cap decorative film bonding device is a specialized device used to bond films made of materials such as PVC, PET, and OPP with printed patterns or text onto the surface of bottle caps. Its core function is to combine the decorative film with the bottle cap through mechanical, pneumatic, or servo control methods, ensuring that the pattern is not deformed, bubble-free, or wrinkle-free, so as to obtain bottle cap products that meet the requirements.

[0003] Chinese patent provides an automatic hot-press film applicator for bottle caps, publication number CN219838208U, which includes a support frame, a hot-pressing mechanism, and a positioning mechanism. The hot-pressing mechanism includes a telescopic cylinder, a connecting frame, a hot-pressing component, and a film roll. The telescopic cylinder passes through the support frame and is connected to the connecting frame. The hot-pressing component is connected to the connecting frame, and the film roll is connected to the side end of the connecting frame.

[0004] The above-mentioned device uses a robotic arm to place bottle caps on the feeding platform onto positioning columns, and then moves the positioning plate back to its original position under the rotation of the lead screw. This structure can realize automatic feeding, avoiding the high labor costs caused by manual feeding. When the film is hot-pressed, the waste film is wound onto the waste film roll, eliminating the need to constantly replace the film and improving the film application efficiency. However, its cap fixing structure is relatively simple. The cap is set at the positioning post, and there are no other external fixing measures. The cap is easy to move when applying the film, which affects the film application effect. At the same time, the positioning post is used to fix the size and support the cap, which is difficult to be compatible with caps of different diameters. It can only support bottle caps, and dust is easy to accumulate on the surface of bottle caps. Applying the film directly under these conditions may affect the film application effect. Utility Model Content

[0005] The purpose of this invention is to provide a device for applying decorative film to the surface of a lid, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A decorative film bonding device for a lid surface includes a worktable and a sliding seat. The sliding seat is installed above the worktable. A support frame is slidably installed inside the worktable. A slider is fixedly connected to one side of the support frame. A lead screw is threaded through the front and rear ends of the slider. Several support platforms are provided at the top of the support frame. An adjustment motor is installed at one side of the rear end of the workbench. The lead screw is rotatably mounted on one side of the workbench via a bearing. The drive shaft of the adjustment motor is connected to the rear end of the lead screw. Vacuum adsorption micropores are provided at the top of several support platforms, and negative pressure adsorption tubes are connected to the bottom of the support platforms. A connecting pipe is connected to the end of several negative pressure adsorption tubes away from the support platforms. An adjustment groove matching the connecting pipe is opened on the side of the workbench away from the lead screw. A telescopic hose is connected to the end of the connecting pipe away from the negative pressure adsorption tube, and a solenoid valve is provided at the connection between the connecting pipe and the telescopic hose.

[0007] Preferably, the negative pressure adsorption tube and the connecting tube are hollow rigid tubes, and the telescopic hose is a corrugated telescopic hollow hose.

[0008] Preferably, the top of the support platform is provided with a cover body, and a telescopic cylinder is installed at the center of the top of the sliding seat. The telescopic push rod of the telescopic cylinder passes through the upper and lower ends of the sliding seat and is connected to a film-applying component that is compatible with the cover body.

[0009] Preferably, an ionizer is installed on the top of the workbench near the solenoid valve, and a dust suction port adapted to the ionizer is installed on the top of the workbench away from the ionizer.

[0010] Preferably, the top of the suction port is provided with several connection holes, and the suction port is connected to a suction pipe through the connection holes.

[0011] Preferably, the side of the ion air bar away from the worktable is connected to an air blowing pipe, and an air valve is provided at the rear end of the air blowing pipe. The side of the ion air bar near the worktable is provided with several air outlets.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a flexible telescopic hose, a support platform, vacuum adsorption micropores, a negative pressure adsorption tube, a connecting tube, and a cover body that work together. Because the top surface of the support platform has vacuum adsorption micropores, the telescopic hose can be connected to an external high-speed vacuum pump to firmly adsorb the cover body onto the top surface of the support platform using negative pressure, preventing the cover body from moving during film application. At the same time, it eliminates the need for multiple positioning posts, making it easy to fix cover bodies of different diameters. Furthermore, it eliminates the need to change clamps during fixing, resulting in high flexibility in use.

[0013] By setting up an ion blower, a dust extraction port, and a dust extraction pipe in conjunction with the cover body, plasma air can be blown out by activating the ion blower before applying the film, thus neutralizing the static electricity on the surface of the cover body. By connecting the dust extraction pipe to an external dust pump, loose dust and other particles on the top surface of the cover body can be sucked away, facilitating dust removal during film application. At the same time, after the static electricity on the surface of the cover body is eliminated, dust can be avoided, reducing the impact on the film application effect. Attached Figure Description

[0016] 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. Example

[0017] Combination Figures 1-3 A decorative film bonding device for a lid surface includes a workbench 1 and a sliding seat 2. The sliding seat 2 is installed above the workbench 1. A support frame 3 is slidably installed inside the workbench 1. A slider is fixedly connected to one side of the support frame 3. A lead screw 4 is threaded through the front and rear ends of the slider. Several support platforms 6 are provided at the top of the support frame 3.

[0018] See Figure 2 and Figure 3Furthermore, an adjustment motor 5 is installed at one side of the rear end of the workbench 1. A lead screw 4 is rotatably mounted on one side of the workbench 1 via a bearing. The drive shaft of the adjustment motor 5 is connected to the rear end of the lead screw 4. Vacuum adsorption micropores 7 are provided at the top of several support platforms 6, and negative pressure adsorption tubes 9 are connected to the bottom of the support platforms 6. A connecting pipe 10 is connected to the end of several negative pressure adsorption tubes 9 away from the support platforms 6. An adjustment groove matching the connecting pipe 10 is opened on the side of the workbench 1 away from the lead screw 4. A telescopic hose 12 is connected to the end of the connecting pipe 10 away from the negative pressure adsorption tube 9, and a solenoid valve 11 is provided at the connection between the connecting pipe 10 and the telescopic hose 12. The negative pressure adsorption tube 9 and the connecting pipe 10 are hollow rigid tubes, and the telescopic hose 12 is a corrugated telescopic hollow hose. A cover body 8 is provided at the top of the support platform 6. A telescopic cylinder is installed at the center of the top of the sliding seat 2, and the telescopic push rod of the telescopic cylinder passes through the upper and lower ends of the sliding seat 2 and is connected to a film-applying assembly 13 matching the cover body 8.

[0019] Specifically, after the cover body 8 is placed on the support platform 6, because the top surface of the support platform 6 is provided with vacuum adsorption micropores 7, and the bottom end of the support platform 6 is connected to a negative pressure adsorption tube 9, and the negative pressure adsorption tube 9 is connected to the telescopic hose 12 through the connecting pipe 10, the end of the telescopic hose 12 away from the connecting pipe 10 can be connected to an external high-speed vacuum pump in advance. Then the high-speed vacuum pump can be started and the solenoid valve 11 can be opened, thereby generating negative pressure to firmly adsorb the cover body 8 onto the top surface of the support platform 6 for precise positioning, so as to avoid the position of the cover body 8 shifting when the film-applying assembly 13 lowers the film. At the same time, it is fixed by vacuum adsorption, so there is no need to use positioning columns or other parts. When the size of the cover body 8 does not change much, there is no need to replace the clamps or other devices, making it highly applicable. Example

[0020] See Figure 2 Furthermore, based on Embodiment 1, an ion fan bar 14 is installed on the top of the workbench 1 near the solenoid valve 11, and a dust suction port 15 adapted to the ion fan bar 14 is installed on the top of the workbench 1 away from the ion fan bar 14. The top of the dust suction port 15 is provided with several connection holes, and the dust suction port 15 is connected to a dust suction pipe 16 through the connection holes. An air blowing pipe is connected to the side of the ion fan bar 14 away from the workbench 1, and an air valve is provided at the rear end of the air blowing pipe. Several air outlets are provided on the side of the ion fan bar 14 near the workbench 1.

[0021] Specifically, before applying the film, after the material is loaded onto the cover body 8 and the support frame 3 is reset, the ion air bar 14 can be activated to cause corona discharge at the tip of the tungsten needle, generating a large number of positive and negative ions. At the same time, the air valve connected to the ion air bar 14 can be opened to blow ions onto the surface of the cover body 8 to neutralize the static electricity on the surface of the cover body 8 and blow off most of the dust and other particles. Meanwhile, the dust suction pipe 16 can be connected to an external dust pump. Subsequently, by activating the external dust pump, suction force can be generated at the dust suction port 15 to suck up loose dust and other particles from the top surface of the cover body 8, thus completing the dust removal process before applying the film and reducing the impact on the film application effect.

[0022] In actual operation, the existing technology involves adjusting the position of the support frame 3 and coordinating with the external robotic arm for loading, which will not be elaborated here. After the cover body 8 has been placed on the support platform 6, the top surface of the support platform 6 is provided with vacuum adsorption micropores 7, and the bottom end of the support platform 6 is connected to a negative pressure adsorption tube 9. At the same time, the negative pressure adsorption tube 9 is connected to the telescopic hose 12 through the connecting pipe 10. At this time, the end of the telescopic hose 12 away from the connecting pipe 10 can be connected to the external high-speed vacuum pump in advance. Then, the high-speed vacuum pump can be started and the solenoid valve 11 can be opened, thereby generating negative pressure to firmly adsorb the cover body 8 on the top surface of the support platform 6 for precise positioning. This avoids the position of the cover body 8 shifting when the film-applying assembly 13 lowers and presses the film. At the same time, the cover body 8 is fixed by vacuum adsorption, which does not require the use of positioning columns or other parts. When the size of the cover body 8 does not change much, there is no need to replace the clamps or other devices, making it highly applicable. Before applying the film, after the material is loaded onto the cover body 8 and the support frame 3 is reset, the ion air bar 14 can be activated to cause corona discharge at the tip of the tungsten needle inside, which can generate a large number of positive and negative ions. At the same time, the air valve connected to the ion air bar 14 can be opened, so that ions can be blown toward the surface of the cover body 8 to neutralize the static electricity on the surface of the cover body 8, and at the same time, most of the dust and other particles can be blown off. Simultaneously, the vacuum pipe 16 can be connected to an external dust pump. By activating the external dust pump, suction can be generated at the vacuum port 15 to remove loose dust and other particles from the top surface of the cover body 8, thus completing the dust removal process before applying the film and reducing the impact on the film application effect.

[0023] Furthermore, the display and control components and modules used in the aforementioned ion fan bar 14, regulating motor 5, external ash pump, external high-speed vacuum pump, and solenoid valve 11 are all existing technologies, which can be fully implemented by those skilled in the art. The power supply is also common knowledge in the field and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
