Description

Technical Field

[0001] This utility model relates to the field of surface coating technology for hangers, and in particular to an automatic surface coating machine for hangers. Background Technology

[0002] Anime-themed plastic pendants are small, wearable ornaments made of plastic, designed based on anime characters, scenes, and logos. Because plastic pendants are easily scratched during transportation, display, or daily use, they need to be coated with a film. The resulting transparent protective layer effectively isolates them from external forces and reduces the risk of surface damage.

[0003] During the lamination process, the plastic film and the surface of the hanger may not adhere tightly due to differences in materials or improper surface treatment, resulting in bubbles, wrinkles, or delamination. This seriously affects the lamination quality, requires rework, and slows down the lamination speed, making it impossible to meet the needs of large-scale production. Utility Model Content

[0004] Based on this, the present invention provides an automatic coating machine for the surface of hangers. It has a simple structure and is easy to use. The grippers pull the plastic film to cover the hanger, and the pressure roller rolls on the surface of the hanger. This effectively solves the problems of air bubbles, wrinkles or delamination that may exist between the hanger surface and the plastic film, effectively improves the tightness of the bonding and ensures the coating quality.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Please see Figures 1 to 6 The automatic coating machine for the surface of the hanger, as described in one embodiment of the present invention, includes a worktable 10, a fixture 20 slidably mounted on the worktable 10, a film covering assembly 30 mounted on the worktable 10, and a rolling assembly 40 located above the film covering assembly 10.

[0032] The top surface of the workbench 10 has a guide frame 11, which is used to position and accommodate the fixture 20.

[0033] The fixture 20 includes a base plate 21, a carrier plate 22 located above the base plate 21, and a vacuum generator 23 installed between the base plate 21 and the carrier plate 22. The base plate 21 is fitted inside the guide frame 11, and the carrier plate 22 is used to support the hanger to be coated.

[0034] In this embodiment, the carrier plate 22 is provided with an adsorption hole 220 in the middle. The adsorption hole 220 is connected downward to the vacuum generator 23. The negative pressure is used to tightly adsorb the hanger, ensuring the clamping stability of the hanger during the coating process.

[0035] The film covering assembly 30 includes a support frame 31 mounted on the top surface of the workbench 10, a first transverse plate 32 slidably mounted inside the support frame 31, grippers 33 mounted at opposite ends of the first transverse plate 32, a pressure plate 34 vertically connected below the first transverse plate 32, a first rodless cylinder 35 mounted on one side of the support frame 31, and film-feeding rollers 36 spaced apart at one end of the support frame 31. The film-feeding rollers 36 are used to feed plastic film, and the grippers 33 are used to hold opposite ends of the plastic film to pull the plastic film to cover the top surface of the hanger. The width of the plastic film is greater than the width of the hanger.

[0036] Specifically, the support frame 31 is positioned above the guide frame 11, that is, the support frame 31 is located above the fixture 20; the first transverse plate 32 and the pressure plate 34 are both located above the fixture 20.

[0037] In this embodiment, the first rodless cylinder 35 is a magnetically coupled rodless cylinder, and the slider of the first rodless cylinder 35 is connected to the first transverse plate 32 to drive the first transverse plate 32 to slide.

[0038] In this embodiment, the gripper 33 is a pneumatic finger that, in conjunction with the movement of the first transverse plate 32, periodically pulls the plastic film covering the top surface of the hanger.

[0039] In this embodiment, the pressure plate 34 is connected to the first transverse plate 32 via a pressure plate drive cylinder 340. Specifically, the cylinder body of the pressure plate drive cylinder 340 is fixedly installed on the top surface of the first transverse plate 32, and the piston rod of the pressure plate drive cylinder 340 passes through the first transverse plate 32 and connects downward to the pressure plate 34, so as to realize the liftable connection between the pressure plate 34 and the first transverse plate 32.

[0040] The rolling assembly 40 includes an extension frame 41 mounted on the top surface of the workbench 10, a second transverse plate 42 slidably mounted on the top of the extension frame 41, a pressure roller 43 that can be lifted and lowered and connected below the second transverse plate 42, a heating rod (not shown) coaxially mounted inside the pressure roller 43, a second rodless cylinder 44 connected to the top of the extension frame 41, and a cutting blade 45 that can be lifted and lowered and connected to one end of the extension frame 41 near the film feeding roller 36.

[0041] Specifically, the riser 41 is mounted above the support frame 31, and the second rodless cylinder 44 is a magnetically coupled rodless cylinder. The slider of the second rodless cylinder 44 is connected to the second transverse plate 42 to drive the second transverse plate 42 to slide.

[0042] like Figure 5 and Figure 6 As shown, the initial position of the gripper 33 is close to the film feeding roller 36, and the initial position of the pressure roller 43 is far from the film feeding roller 36. The initial position of the gripper 33 is located outside the fixture 20, and the space between the gripper 33 and the fixture 20 is used for the cutting blade 45 to fall and cut the plastic film.

[0043] In practical operation, the film-releasing roller 36 releases the plastic film, and after the grippers 33 clamp the opposite sides of the plastic film, the first rodless cylinder 35 drives the first transverse plate 32 to move, thereby pulling the plastic film to initially cover the surface of the hanger. Then, the pressure roller 43 falls and abuts against the plastic film, making it tightly adhere to the surface of the hanger. Next, the second rodless cylinder 44 drives the pressure roller 43 to roll back and forth along the top surface of the hanger. The heating rod heats and softens the plastic film, simultaneously expelling gas between the film layers, effectively solving the problems of bubbles, wrinkles, or delamination that may exist between the hanger surface and the plastic film, effectively improving the tightness of the adhesion and ensuring the quality of the coating. After the pressure roller 43 rolls back and forth, it returns to its initial position for reset. At this time, the grippers 33 release the plastic film and return to their initial position for reset. After reset, the grippers 33 clamp the opposite sides of the plastic film again, and at the same time, the pressure plate 34 falls and presses against the plastic film and the hanger. Finally, the cutting blade 45 falls between the gripper 33 and the fixture 20, cutting the plastic film and completing the surface coating of a single hanger. The hanger that has completed surface coating is then removed by the operator, replaced with a new hanger, and the next round of surface coating is performed. This cycle effectively improves coating quality and efficiency, meeting the needs of large-scale production.

[0044] In this embodiment, the length direction of the second transverse plate 42 is consistent with the length direction of the first transverse plate 32, and the second transverse plate 42 is located above the first transverse plate 32.

[0045] In this embodiment, the pressure roller 43 is connected to the second transverse plate 42 via a pressure roller drive cylinder 430. Specifically, the cylinder body of the pressure roller drive cylinder 430 is fixedly installed on the top surface of the second transverse plate 42, and the piston rod of the pressure roller drive cylinder 430 passes through the second transverse plate 42 and connects downward to the pressure roller 43, so as to realize the liftable connection between the pressure roller 43 and the second transverse plate 42.

[0046] In this embodiment, the movement direction of the first rodless cylinder 35 is the same as that of the second rodless cylinder 44.

[0047] In this embodiment, the cutting blade 45 is connected to the extension frame 41 via a cutting drive cylinder 450. Specifically, the cylinder body of the cutting drive cylinder 450 is fixedly connected to the top of the extension frame 41, and the piston rod of the cutting drive cylinder 450 is connected downward to the cutting blade 45, so as to realize the lifting connection between the cutting blade 45 and the extension frame 41.

[0048] The above-mentioned automatic coating machine for hangers has a simple structure and is easy to use. The gripper 33 pulls the plastic film to cover the hanger, and the pressure roller 43 rolls on the surface of the hanger, which effectively solves the problems of bubbles, wrinkles or delamination that may exist between the hanger surface and the plastic film, effectively improves the tightness of the bonding and ensures the coating quality.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
