[0025] The following further details the features and other related features of the utility model through embodiments for the understanding of those skilled in the same industry:

[0026] Referring to Figures 1 - 3 , an embodiment of a pulling and rotating film pasting device of the utility model is proposed:

[0027] A pulling and rotating film pasting device includes a workpiece table 2 for fixing a box-shaped workpiece 1. A film output mechanism 4 is provided on the left of the workpiece table 2, and a film clamping mechanism 3 for clamping the film output by the film output mechanism 4 to the right of the box-shaped workpiece 1. A film cutting mechanism 5 is provided between the film output mechanism 4 and the box-shaped workpiece 1. The workpiece table 2 is connected with a rotating mechanism 6. A film pressing mechanism is provided above the workpiece table 2. The film pressing mechanism includes a pressing block 71 and a lifting component 72 for driving the pressing block 71 to lift. The pressing block 71 includes a horizontal pressing plate 711 for pressing the film on the upper end face of the box-shaped workpiece 1, and vertical pressing plates 712 are provided on both the left and right sides of the horizontal pressing plate 711 for pressing the film onto the left and right side faces of the box-shaped workpiece 1.

[0028] As Figure 1 shown, the material pulling and rotating film sticking device further includes a front-back moving mechanism 73 for moving the lifting member 72 and the pressing block 71 in the front-back direction.

[0029] The process of pulling and sticking the film of the present utility model is as follows: First, the box-shaped workpiece 1 is fixed on the workpiece table 2. Then, the film sticking mechanism 4 outputs the film to be stuck. The film clamping mechanism 3 pulls the film output by the film sticking mechanism 4 to the right side of the box-shaped workpiece 1. Then, the film cutting mechanism 5 cuts the film. The pressing block 71 descends, and the horizontal pressing plate 711 presses the film on the upper end surface of the box-shaped workpiece 1, so that the film is firmly connected to the upper end surface of the box-shaped workpiece 1. The vertical pressing plate 712 presses the film onto the left and right side surfaces of the box-shaped workpiece 1. After the first film pressing is completed, the pressing block 71 rises, and the rotating mechanism 6 drives the workpiece table 2 and the box-shaped workpiece 1 to rotate 90° with the left-right direction as the rotation axis. After that, the pressing block 71 descends, and the vertical pressing plate 712 presses the film onto the left and right side surfaces of the box-shaped workpiece 1 again. At the same time, the front-back moving mechanism 73 moves the pressing block 71 in the front-back direction, further making the film firmly connected to the left and right side surfaces of the box-shaped workpiece 1.

[0030] The present utility model can make the film connected to three surfaces of the box-shaped workpiece 1 through the orderly cooperation of the film sticking mechanism 4, the film clamping mechanism 3, the film cutting mechanism 5, and the film pressing mechanism, and the connection is more stable. Moreover, no manual operation is required during the film sticking process, and the film sticking efficiency is higher.

[0031] The workpiece table 2 includes a clamping assembly for clamping the box-shaped workpiece 1 in the front-back direction. The rotating mechanism 6 includes a first frame 61 and a rotating cylinder 62 installed on the first frame 61. As Figure 3 shown, the box-shaped workpiece 1 is of a stepped structure, the height of the front part of the box-shaped workpiece 1 is lower than that of the rear part. The clamping assembly includes a base 21, and a workpiece groove 211 for placing the front part of the box-shaped workpiece 1 is provided at the rear of the base 21. A pressing plate 22 for pressing against the rear side surface of the box-shaped workpiece 1 is connected behind the base 21, and the left side of the base 21 is connected to the output end of the rotating cylinder 62. The base 21 is provided with a clamping cylinder 23 and two connecting ears 24. The pressing plate 22 is provided with a connecting shaft extending in the left-right direction, and the pressing plate 22 is rotatably connected to the two connecting ears 24 through the connecting shaft respectively. When the workpiece table 2 needs to fix the box-shaped workpiece 1, the output end of the clamping cylinder 23 pushes the pressing plate 22, so that the pressing plate 22 can tightly press the box-shaped workpiece 1. When it is necessary to remove the box-shaped workpiece 1 after the film sticking is completed, the output end of the clamping cylinder 23 pushes the pressing plate 22, so that the pressing plate 22 releases the box-shaped workpiece 1, facilitating the removal of the box-shaped workpiece 1.

[0032] As Figure 1As shown in the figure, the material pulling and rotary film sticking device further includes a second frame 8, and the film discharging mechanism 4 is installed on the second frame 8. The film discharging mechanism 4 includes a reel 41 for storing the film sticking material roll, a guiding seat 42, and at least one guiding shaft 43. The guiding shaft 43 is located between the guiding seat 42 and the reel 41. The guiding seat 42 is provided with a guiding groove 421 for the film to pass through. The guiding groove 421 penetrates the guiding seat 42 in the left-right direction. The reel 41 outputs the film, and the film is guided by the guiding shaft 43 and conveyed to the left end of the guiding groove 421, and then the film passes through the guiding groove 421 to the film clamping mechanism 3. Limited plates 431 are provided at both ends of the guiding shaft 43, and the distance between the two limited plates 431 is the same as the width of the film. Under the action of the two limited plates 431, the film will not shift during the conveying process.

[0033] The material pulling and rotary film sticking device further includes a pressing rod (not shown in the attached figure) that can be lifted and lowered. A through hole 422 communicating with the guiding groove 421 is provided at the top of the guiding seat 42. When the film is cut by the film cutting mechanism 5, the pressing rod presses on the film after passing through the through hole 422, so that the film does not move during the cutting process. When the film is cut by the film cutting mechanism 5, the pressing rod presses on the film after passing through the through hole 422, so that the film does not move during the cutting process. When the film clamping mechanism 3 pulls the film, the pressing rod rises and does not contact the film.

[0034] As Figure 2 shown in the figure, the film clamping mechanism 3 includes a cylinder gripper 31 and a left-right moving assembly 32 for driving the cylinder gripper 31 to move in the left-right direction.

[0035] The film cutting mechanism 5 includes a cutting knife 51 and a first cylinder 52 located above the guiding seat 42. The cutting knife 51 is connected to the output end of the first cylinder 52, and the first cylinder 52 is used to drive the cutting knife 51 to lift and lower.

[0036] The front-back moving mechanism 73 includes a second cylinder 731 installed on the second frame 8 and a first connecting plate 732 connected to the output end of the second cylinder 731. The first cylinder 52 and the lifting member 72 are both installed on the first connecting plate 732, so that the pressing block 71 and the cutting knife 51 can both move back and forth. The left-right moving assembly 32 includes a third cylinder 321 installed on the second frame 8 and a second connecting plate 322 connected to the output end of the third cylinder 321. The cylinder gripper 31 is installed on the second connecting plate 322.

Any equivalent structural transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
