Specific embodiments

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Refer to Figure 1 - Figure 10 , a device for attaching an inner decorative film of a cosmetic box, including a workbench 1, and two moving plates 2 are connected to the workbench 1 through a connecting mechanism. The side walls of the two moving plates 2 away from each other are fixedly connected to a cross plate 4 through a plurality of first rods 3.

[0035] The connecting mechanism includes two hydraulic cylinders 21 fixedly connected to the lower end of the workbench 1. The moving ends of the two hydraulic cylinders 21 are jointly fixedly connected to a third plate 22. The upper end of the third plate 22 is fixedly connected to two L-shaped plates 23. The side walls of the two L-shaped plates 23 are both slidably connected to the side wall of the workbench 1. The side walls of the two L-shaped plates 23 away from the third plate 22 are jointly fixedly connected to a connecting table 24. A groove 25 (as Figure 6 shown) is opened at the lower end of the connecting table 24. The side walls of the two moving plates 2 are both 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. The side walls of the two moving plates 2 are both threadedly connected to the side wall of the bidirectional lead screw 26.

[0037] A first motor 27 is fixedly connected to the upper end of the connecting platform 24. Synchronous wheels 28 are fixedly connected to the side walls 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 wheels 28. Further, the synchronous belt penetrates through the inner top of the groove 25.

[0038] The fitting mechanism, the fitting mechanism includes a cross cavity 5 opened in the cross plate 4 (as Figure 3 shown), four first L-shaped rods 6 are slidably connected to the inner wall of the cross cavity 5. A second rod 11 is slidably connected to the side walls of the four first L-shaped rods 6. A second L-shaped rod 7 is fixedly connected to the side wall of the second rod 11. The side walls of the first L-shaped rod 6 and the second L-shaped rod 7 are in contact with each other. An adsorption box 8 is fixedly connected to the side wall of the second L-shaped rod 7 away from the first L-shaped rod 6. A plurality of adsorption holes 9 are opened in the inner wall of the adsorption box 8 away from the second L-shaped rod 7. The adsorption box 8 is fixedly communicated with an air extraction pipe 10.

[0039] As Figure 3 shown, the four adsorption boxes 8 can adsorb the four corners of the decorative film, and fit the four corners of the decorative film with the inner wall of the cosmetic box. Then the whole decorative film will be fitted with the inner wall of the cosmetic box. First, the middle position of the decorative film can be heat-sealed, and then its periphery can be heat-sealed, avoiding the situation in the prior art where the adsorption box 8 is in contact with the middle position of the decorative film. Then, when heat-sealing, the periphery of the decorative film will be heat-sealed first, which is likely to cause air to exist inside the decorative film and affect the appearance quality of the heat-sealing of the middle position of the decorative film.

[0040] A first plate 12 is fixedly connected to the side wall of the second rod 11 away from the second L-shaped rod 7. 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. Sliding plates 14 are fixedly connected to the lower ends of the two second L-shaped rods 7 located above, and fixing frames 15 are fixedly connected to the upper ends of the two second L-shaped rods 7 located below (as Figure 3 and Figure 4 shown). The side walls of the two sliding plates 14 are in contact with the inner walls of their corresponding fixing frames 15. Two cylinders 16 are fixedly connected to the side wall of the cross plate 4. The movable ends of the two cylinders 16 are both facing the side walls of their corresponding fixing frames 15 (as Figure 4 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 walls of the four first L-shaped rods 6 through four first rotating rods 18 (as Figure 3 and Figure 7 shown). Two electric push rods 19 are fixedly connected to the side wall of the cross plate 4 away from the adsorption box 8. A second plate 20 is fixedly connected to the common movable ends of the two electric push rods 19. The side wall of the second plate 20 is fixedly connected to the side wall of the sliding rod 17 (as Figure 7 shown).

[0042] When the sliding rod 17 slides on the inner wall of the cross-shaped cavity 5, at this time, the sliding rod 17 drives the four first L-shaped rods 6 to slide on the inner wall of the cross-shaped 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, and the distance between the four adsorption boxes 8 can be adjusted. And when the upper and lower two adsorption boxes 8 on the same side move, at this time, the sliding plate 14 moves on the inner wall of the fixed frame 15, so that the upper and lower two adsorption boxes 8 on the same side are always connected together. Subsequently, according to the size of the inner wall of the cosmetic box, the two cylinders 16 are adjusted to extend or contract. At this time, the two fixed frames 15 move left and right under the elastic force of the multiple springs 13 and the extrusion force of the two cylinders 16 (as Figure 3 and Figure 4 shown), driving the upper and lower two adsorption boxes 8 on the same side to move, so that the size of the area formed by the four adsorption boxes 8 is the same as the size of the inner wall of the cosmetic box (the distance between the upper and lower two adsorption boxes 8 on the same side is the same as the height of the inner wall of the cosmetic box, and the distance between the left and right two adsorption boxes 8 on the same side is the same as the length of the inner wall of the cosmetic box), and the inner wall of the cosmetic box with different sizes can be fitted with the decorative film without changing the size of the four adsorption boxes 8, avoiding the need to change the size of the adsorption box 8 when fitting the decorative film on the inner wall of the cosmetic box with different sizes in the prior art.

[0043] A circular hole 29 is opened on the inner side wall of the cross-shaped cavity 5 close to the adsorption box 8, and an annular groove 30 is opened on the side wall of the cross-shaped plate 4 close to the adsorption box 8. An arc-shaped plate 31 that can rotate is slidably connected to the inner wall of the annular groove 30. A side wall of the arc-shaped plate 31 far from the annular groove 30 is fixedly connected with an L-shaped pipe 32. A plurality of air jet holes 33 are opened on the inner wall of the L-shaped pipe 32 in the vertical direction. A moving pipe 34 that can move up and down is slidably connected to the inner wall of the L-shaped pipe 32 in a sealed manner. An air jet groove 35 is opened on the inner wall of the moving pipe 34 facing the air jet holes 33 (as Figure 7 shown).

[0044] A round rod 36 is rotatably connected through the side walls of the sliding rod 17 and the second plate 20. One end of the round rod 36 close to the L-shaped pipe 32 is fixedly connected with a rectangular rod 37. A rectangular groove 38 is opened at one end of the L-shaped pipe 32. The side wall of the rectangular rod 37 is slidably connected to the inner side wall of the rectangular groove 38 in a sealed manner. A rigid pipe 39 is fixedly connected through the inner walls of the round rod 36 and the rectangular rod 37. The side wall of the second plate 20 is fixedly connected with a rotary joint 40 through a bracket. One end of the rigid pipe 39 far from the rectangular rod 37 is fixedly connected with one side of the rotary joint 40. The other side of the rotary joint 40 is fixedly connected with a hot air pipe 41. 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. A gear 43 is 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 are meshed with each other (asFigure 10 as shown

[0046] When the decorative film is attached to the inner wall of the cosmetic box by the four adsorption boxes 8, at this time, 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, the rigid pipe 39 and the rectangular groove 38. Then, the hot air flows to the middle position of the decorative film through the plurality of air injection holes 33 and the air injection groove 35, and thermoplastic treatment is performed on the middle position thereof. And at this time, the second motor 42 is driven to rotate, the round rod 36 is driven to rotate by the two gears 43, and then the L-shaped pipe 32 is driven to rotate through the rectangular rod 37 and the rectangular groove 38, and the moving pipe 34 is driven to rotate, so as to complete the thermoplastic treatment of the middle position of the decorative film, and only the periphery needs to be thermoplastically treated subsequently.

[0047] The side wall of the arc-shaped plate 31 is slidably connected with a third L-shaped rod 44, the upper end of the moving pipe 34 is fixedly connected with the lower end of the top of the third L-shaped rod 44, and the side wall of the rectangular rod 37 is rotatably connected with the lower part of the side wall of the third L-shaped rod 44 through a second rotating rod 45 (as Figure 8 shown

[0048] When the sliding rod 17 moves in the direction close to the L-shaped pipe 32, the distance between the four adsorption boxes 8 increases at this time, that is, the area of the attached decorative film increases. At this time, the movement of the sliding rod 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, driving the moving pipe 34 to move upward, increasing the area when the L-shaped pipe 32 and the moving pipe 34 rotate, and increasing the thermoplastic effect on the middle position of the decorative film;

[0049] When the sliding rod 17 moves in the direction away from the L-shaped pipe 32, the distance between the four adsorption boxes 8 decreases at this time, that is, the area of the attached decorative film decreases. At this time, the movement of the sliding rod 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, driving the moving pipe 34 to move downward, synchronously reducing the area when the L-shaped pipe 32 and the moving pipe 34 rotate.

[0050] When thermoplastic film is attached to the inside of the cosmetic box, first, according to the size of the inner wall of the cosmetic box, at this time, the two electric push rods 19 are adjusted to extend or contract, driving the second plate 20 and the sliding rod 17 to move left and right (as Figure 7As shown in the figure, at this time, the sliding rod 17 drives the four first L-shaped rods 6 to slide on the inner wall of the cross-shaped 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, so that the distance between the four adsorption boxes 8 can be adjusted. And when the upper and lower two adsorption boxes 8 on the same side move, at this time, the sliding plate 14 moves on the inner wall of the fixed frame 15, so that the upper and lower two adsorption boxes 8 on the same side are always connected together. Subsequently, according to the size of the inner wall of the cosmetic box, the two cylinders 16 are adjusted to extend or contract. At this time, the two fixed frames 15 move left and right under the elastic force of the multiple springs 13 and the extrusion force of the two cylinders 16 (as shown in Figure 3 and Figure 4 shown), driving the upper and lower two adsorption boxes 8 on the same side to move, so that the size of the area formed by the four adsorption boxes 8 is the same as the size of the inner wall of the cosmetic box (the distance between the upper and lower two adsorption boxes 8 on the same side is the same as the height of the inner wall of the cosmetic box, and the distance between the left and right two adsorption boxes 8 on the same side is the same as the length of the inner wall of the cosmetic box), and the inner wall of the cosmetic box of different sizes can be fitted with the decorative film;

[0051] When the sliding rod 17 moves in the direction close to the L-shaped tube 32, the distance between the four adsorption boxes 8 increases at this time, that is, the area of the decorative film to be fitted increases. At this time, the movement of the sliding rod 17 drives the round rod 36 and the rectangular rod 37 to move. Furthermore, the rectangular rod 37 drives the third L-shaped rod 44 to slide upward through the second rotating rod 45, driving the moving tube 34 to move upward, increasing the area when the L-shaped tube 32 and the moving tube 34 rotate, and increasing the thermoplastic effect on the middle position of the decorative film;

[0052] When the sliding rod 17 moves in the direction away from the L-shaped tube 32, the distance between the four adsorption boxes 8 decreases at this time, that is, the area of the decorative film to be fitted decreases. At this time, the movement of the sliding rod 17 drives the round rod 36 and the rectangular rod 37 to move. Furthermore, the rectangular rod 37 drives the third L-shaped rod 44 to slide downward through the second rotating rod 45, driving the moving tube 34 to move downward, and synchronously reducing the area when the L-shaped tube 32 and the moving tube 34 rotate;

[0053] Subsequently, the cosmetic box is placed on the workbench 1, and the air in the adsorption box 8 is sucked through the air extraction pipe 10. Furthermore, the eight adsorption boxes 8 can adsorb the four corners of the two decorative films through the multiple adsorption holes 9. Subsequently, the two hydraulic cylinders 21 are adjusted to extend, and the connecting platform 24 is driven to move downward through the third plate 22 and the two L-shaped plates 23, so that the two decorative films move downward and face the inner wall of the cosmetic box. Subsequently, the first motor 27 is driven to rotate forward, and the two-way lead screw 26 is rotated forward through the two synchronous wheels 28 and the synchronous belt, so that the two moving plates 2 move away from each other, driving the two decorative films to move away from each other, so that the two decorative films are fitted with the inner wall of the cosmetic box;

[0054] Subsequently, air is pumped into the hot air pipe 41 through an external hot air pump. Then, the hot air enters the L-shaped pipe 32 and the movable pipe 34 through the rotary joint 40, the rigid pipe 39, and the rectangular groove 38. Subsequently, the hot air flows to the middle position of the decorative film through a plurality of air injection holes 33 and the air injection groove 35, and thermoplastic treatment is performed on the middle position. At this time, the second motor 42 is driven to rotate, the round rod 36 is driven to rotate through two gears 43, and then the L-shaped pipe 32 is driven to rotate through the rectangular rod 37 and the rectangular groove 38, and the movable pipe 34 is also driven to rotate, completing the thermoplastic treatment of the middle position of the decorative film. Only the subsequent thermoplastic treatment of its periphery is required.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
