Description

Technical Field

[0001] This invention relates to the field of cosmetic box manufacturing technology, and specifically to a device for bonding an internal decorative film to a cosmetic box. Background Technology

[0002] As cosmetics become increasingly diverse and services become more sophisticated, decorative films are often applied inside cosmetic boxes to enhance their appearance.

[0003] In existing technologies, when attaching decorative film to the inner wall of a cosmetic box, the decorative film is typically adsorbed using an adsorption box. The adsorption box is then moved to adhere the decorative film to the inner wall of the cosmetic box. Finally, hot air is blown onto the surface of the decorative film, causing it to thermoform and bond to the inner wall. However, in this method, the adsorption box is attached to the center of the decorative film. Therefore, during thermoforming, the edges of the decorative film are thermoformed first, which can easily lead to air pockets inside the film, affecting the appearance quality of the thermoformed area in the center. Furthermore, the size of the adsorption box is fixed, while the inner wall size of cosmetic boxes varies. This means that when attaching decorative film to the inner wall of cosmetic boxes of different sizes, it may be necessary to change the size of the adsorption box. Summary of the Invention

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.

[0034] Reference Figure 1 - Figure 10 A cosmetic box interior decorative film bonding device includes a workbench 1, on which two movable plates 2 are connected by a connecting mechanism. The sidewalls of the two movable plates 2 that are far apart from each other are fixedly connected to cross plates 4 by multiple first rods 3.

[0035] The connecting mechanism includes two hydraulic cylinders 21 fixedly connected to the lower end of the worktable 1. A third plate 22 is fixedly connected to the movable ends of the two hydraulic cylinders 21. Two L-shaped plates 23 are fixedly connected to the upper end of the third plate 22. The sidewalls of the two L-shaped plates 23 are slidably connected to the sidewall of the worktable 1. A connecting platform 24 is fixedly connected to the sidewalls of the two L-shaped plates 23 away from the third plate 22. A groove 25 is provided at the lower end of the connecting platform 24 (e.g., ...). Figure 6 As shown), the side walls of both movable plates 2 are slidably connected to the inner wall of the groove 25.

[0036] The inner wall of the groove 25 is rotatably connected to a bidirectional lead screw 26, and the side walls of the two movable plates 2 are threadedly connected to the side walls of the bidirectional lead screw 26.

[0037] A first motor 27 is fixedly connected to the upper end of the connecting platform 24. Synchronous pulleys 28 are fixedly connected to the side wall of the movable shaft of the first motor 27 and the side wall of the bidirectional lead screw 26. A synchronous belt is connected between the two synchronous pulleys 28. Furthermore, the synchronous belt passes through the top of the groove 25.

[0038] The bonding mechanism includes a cross cavity 5 (e.g., inside the cross plate 4) Figure 3 As shown), four first L-shaped rods 6 are slidably connected to the inner wall of the cross cavity 5. The side walls of the four first L-shaped rods 6 are slidably connected to second rods 11. The side walls of the second rods 11 are fixedly connected to second L-shaped rods 7. The side walls of the first L-shaped rods 6 and the second L-shaped rods 7 are close to each other and fit together. The side wall of the second L-shaped rods 7 away from the first L-shaped rods 6 is fixedly connected to an adsorption box 8. The inner wall of the adsorption box 8 away from the second L-shaped rods 7 has multiple adsorption holes 9. The adsorption box 8 is fixedly connected to a suction pipe 10.

[0039] like Figure 3 As shown, the four adsorption boxes 8 can adsorb the four corners of the decorative film, adhering the four corners of the decorative film to the inner wall of the cosmetic box. Thus, the entire decorative film is also adhered to the inner wall of the cosmetic box. The center of the decorative film can be thermoformed first, and then the surrounding area can be thermoformed. This avoids the situation in the prior art where the adsorption box 8 is adhered to the center of the decorative film, and the surrounding area is thermoformed first during the thermoforming process. This can easily lead to air inside the decorative film, affecting the appearance quality of the thermoformed center of the decorative film.

[0040] The second rod 11 is fixedly connected to the side wall away from the second L-shaped rod 7 by a first plate 12. A spring 13 is sleeved on the side wall of the second rod 11. One end of the spring 13 is fixedly connected to the side wall of the first L-shaped rod 6, and the other end of the spring 13 is fixedly connected to the side wall of the first plate 12. The lower ends of the two upper second L-shaped rods 7 are fixedly connected to a sliding plate 14, and the upper ends of the two lower second L-shaped rods 7 are fixedly connected to a fixing frame 15 (e.g., ...). Figure 3 and Figure 4 As shown), the sidewalls of both slide plates 14 are fitted against the inner wall of their corresponding fixed frames 15. Two cylinders 16 are fixedly connected to the sidewalls of the cross plate 4, with the moving ends of both cylinders 16 facing the sidewalls of their corresponding fixed frames 15 (as shown). Figure 4 (As shown).

[0041] A sliding rod 17 is slidably connected to the inner wall of the cross cavity 5 away from the adsorption box 8. The side wall of the sliding rod 17 is rotatably connected to the side wall of the four first L-shaped rods 6 respectively through four first rotating rods 18 (e.g., Figure 3 and Figure 7 As shown), two electric push rods 19 are fixedly connected to the side wall of the cross plate 4 away from the adsorption box 8. The movable ends of the two electric push rods 19 are fixedly connected to a second plate 20. The side wall of the second plate 20 is fixedly connected to the side wall of the slide rod 17 (as shown). Figure 7 (As shown).

[0042] When the slide rod 17 slides on the inner wall of the cross cavity 5, it drives the four first L-shaped rods 6 to slide on the inner wall of the cross cavity 5 via the four first rotating rods 18. At this time, the four first L-shaped rods 6 drive the four adsorption boxes 8 to move via the four second L-shaped rods 7, which can adjust the distance between the four adsorption boxes 8. When the upper and lower adsorption boxes 8 on the same side move, the slide plate 14 moves on the inner wall of the fixed frame 15, so that the upper and lower adsorption boxes 8 on the same side are always connected together. Then, according to the size of the inner wall of the cosmetic box, the two cylinders 16 are adjusted to extend or retract. At this time, the two fixed frames 15 move left and right under the elastic force of multiple springs 13 and the squeezing force of the two cylinders 16 (e.g., Figure 3 and Figure 4 As shown), the upper and lower adsorption boxes 8 on the same side are moved, so that the size of the area formed by the four adsorption boxes 8 is consistent with the size of the inner wall of the cosmetic box (the distance between the upper and lower adsorption boxes 8 on the same side is consistent with the height of the inner wall of the cosmetic box, and the distance between the left and right adsorption boxes 8 on the same side is consistent with the length of the inner wall of the cosmetic box). This allows decorative films to be applied to the inner walls of cosmetic boxes of different sizes without changing the size of the four adsorption boxes 8, avoiding the need to change the size of the adsorption boxes 8 when applying decorative films to the inner walls of cosmetic boxes of different sizes in the prior art.

[0043] A circular hole 29 is provided on the inner wall of the cross cavity 5 near the adsorption box 8. An annular groove 30 is provided on the side wall of the cross plate 4 near the adsorption box 8. A rotatable arc plate 31 is slidably connected to the inner wall of the annular groove 30. An L-shaped tube 32 is fixedly connected to the side wall of the arc plate 31 away from the annular groove 30. Multiple air jet holes 33 are provided on the vertical inner wall of the L-shaped tube 32. A movable tube 34 that can move up and down is slidably connected to the inner wall of the L-shaped tube 32. An air jet groove 35 is provided on the inner wall of the movable tube 34 opposite to the air jet holes 33 (e.g., Figure 7 (As shown).

[0044] A round rod 36 is rotatably connected through the side wall of the slide rod 17 and the side wall of the second plate 20. A rectangular rod 37 is fixedly connected to the end of the round rod 36 near the L-shaped tube 32. A rectangular groove 38 is opened at one end of the L-shaped tube 32. The side wall of the rectangular rod 37 is slidably connected to the inner side wall of the rectangular groove 38. A rigid tube 39 is fixedly connected through the inner walls of the round rod 36 and the rectangular rod 37. A rotary joint 40 is fixedly connected to the side wall of the second plate 20 through a bracket. The end of the rigid tube 39 away from the rectangular rod 37 is fixedly connected to one side of the rotary joint 40. A hot air pipe 41 is fixedly connected to the other side of the rotary joint 40. It should be noted that the hot air pipe 41 is connected to an external hot air pump.

[0045] A second motor 42 is fixedly connected to the side wall of the second plate 20. Gears 43 are fixedly connected to the side wall of the movable shaft of the second motor 42 and the side wall of the round rod 36. The two gears 43 mesh with each other (e.g., ...). Figure 10 (As shown).

[0046] When the decorative film is attached to the inner wall of the cosmetic box by the four adsorption boxes 8, air is pumped into the hot air pipe 41 by an external hot air pump. Then the hot air enters the L-shaped pipe 32 and the moving pipe 34 through the rotary joint 40, rigid pipe 39 and rectangular groove 38. Then the hot air flows to the middle position of the decorative film through multiple air jet holes 33 and air jet groove 35, and performs thermoforming on the middle position. At this time, the second motor 42 is driven to rotate, which drives the round rod 36 to rotate through two gears 43. In turn, the L-shaped pipe 32 is driven to rotate through the rectangular rod 37 and rectangular groove 38, and the moving pipe 34 is driven to rotate, completing the thermoforming on the middle position of the decorative film. Only the surrounding area needs to be thermoformed afterward.

[0047] A third L-shaped rod 44 is slidably connected to the side wall of the arc-shaped plate 31. The upper end of the moving tube 34 is fixedly connected to the lower end of the top of the third L-shaped rod 44. The side wall of the rectangular rod 37 is rotatably connected to the lower side wall of the third L-shaped rod 44 via a second rotating rod 45 (e.g., Figure 8 (As shown).

[0048] When the slide bar 17 moves closer to the L-shaped tube 32, the distance between the four adsorption boxes 8 increases, which means the area of ​​the decorative film that is adhered increases. At this time, the movement of the slide bar 17 drives the round rod 36 and the rectangular rod 37 to move. Then, the rectangular rod 37 drives the third L-shaped rod 44 to slide upward through the second rotating rod 45, which drives the moving tube 34 to move upward, increasing the area of ​​the L-shaped tube 32 and the moving tube 34 when they rotate, and increasing the thermoplastic effect on the middle position of the decorative film.

[0049] When the slide bar 17 moves away from the L-shaped tube 32, the distance between the four adsorption boxes 8 decreases, which means the area of ​​the attached decorative film decreases. At this time, the movement of the slide bar 17 drives the round rod 36 and the rectangular rod 37 to move. Then, the rectangular rod 37 drives the third L-shaped rod 44 to slide downward through the second rotating rod 45, which drives the moving tube 34 to move downward, and simultaneously reduces the area of ​​the L-shaped tube 32 and the moving tube 34 when they rotate.

[0050] When applying the thermoplastic film to the inside of the cosmetic box, first adjust the two electric push rods 19 to extend or retract according to the inner wall dimensions of the cosmetic box, thereby moving the second plate 20 and the slide rod 17 left and right (e.g., Figure 7As shown), at this time, the slide bar 17 drives the four first L-shaped rods 6 to slide on the inner wall of the cross cavity 5 through the four first rotating rods 18. At this time, the four first L-shaped rods 6 drive the four adsorption boxes 8 to move through the four second L-shaped rods 7, which can adjust the distance between the four adsorption boxes 8. When the upper and lower adsorption boxes 8 on the same side move, the slide plate 14 moves on the inner wall of the fixed frame 15, so that the upper and lower adsorption boxes 8 on the same side are always connected together. Then, according to the size of the inner wall of the cosmetic box, the two cylinders 16 are adjusted to extend or retract. At this time, the two fixed frames 15 move left and right under the elastic force of multiple springs 13 and the squeezing force of the two cylinders 16 (as shown). Figure 3 and Figure 4 As shown), it drives the upper and lower adsorption boxes 8 located on the same side to move, so that the size of the area formed by the four adsorption boxes 8 is consistent with the size of the inner wall of the cosmetic box (the distance between the upper and lower adsorption boxes 8 located on the same side is consistent with the height of the inner wall of the cosmetic box, and the distance between the left and right adsorption boxes 8 located on the same side is consistent with the length of the inner wall of the cosmetic box), so that decorative film can be attached to the inner wall of cosmetic boxes of different sizes.

[0051] When the slide bar 17 moves closer to the L-shaped tube 32, the distance between the four adsorption boxes 8 increases, which means the area of ​​the decorative film that is adhered increases. At this time, the movement of the slide bar 17 drives the round rod 36 and the rectangular rod 37 to move. Then, the rectangular rod 37 drives the third L-shaped rod 44 to slide upward through the second rotating rod 45, which drives the moving tube 34 to move upward, increasing the area of ​​the L-shaped tube 32 and the moving tube 34 when they rotate, and increasing the thermoplastic effect on the middle position of the decorative film.

[0052] When the slide bar 17 moves away from the L-shaped tube 32, the distance between the four adsorption boxes 8 decreases, which means the area of ​​the attached decorative film decreases. At this time, the movement of the slide bar 17 drives the round rod 36 and the rectangular rod 37 to move. Then, the rectangular rod 37 drives the third L-shaped rod 44 to slide downward through the second rotating rod 45, which drives the moving tube 34 to move downward, and simultaneously reduces the area of ​​the L-shaped tube 32 and the moving tube 34 when they rotate.

[0053] The cosmetic box is then placed on the workbench 1, and air is drawn into the adsorption box 8 through the suction pipe 10. The eight adsorption boxes 8 can then adsorb the four corners of the two decorative films through multiple adsorption holes 9. Then, the two hydraulic cylinders 21 are extended, and the connecting platform 24 is moved down through the third plate 22 and the two L-shaped plates 23, so that the two decorative films are moved down and face the inner wall of the cosmetic box. Then, the first motor 27 is driven to rotate forward, and the two synchronous pulleys 28 and the synchronous belt make the bidirectional lead screw 26 rotate forward, so that the two moving plates 2 move away from each other, and move the two decorative films away from each other, so that the two decorative films are attached to the inner wall of the cosmetic box.

[0054] Subsequently, an external hot air pump pumps air into the hot air pipe 41. The hot air then enters the L-shaped pipe 32 and the moving pipe 34 through the rotary joint 40, rigid pipe 39, and rectangular groove 38. The hot air then flows through multiple air jet holes 33 and air jet grooves 35 to the center of the decorative film, where it undergoes thermoforming. At this time, the second motor 42 is driven to rotate, which in turn drives the round rod 36 to rotate through two gears 43. This, in turn, drives the L-shaped pipe 32 to rotate through the rectangular rod 37 and rectangular groove 38, and also drives the moving pipe 34 to rotate, thus completing the thermoforming of the center of the decorative film. Only the surrounding area needs to be thermoformed afterward.

[0055] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
