[0038] As Figure 1 shown, it is a film laminating machine 100 shown in the present utility model, which is used to cover a plastic film on a stacked mobile phone case.

[0039] As Figures 1 to 2 shown, the film laminating machine 100 includes: a frame 10, a film feeding device 20 and a stacking device 30. Among them, the frame 10 is used to install the film feeding device 20 and the stacking device 30. The film feeding device 20 is used to output and control the conveying length of the plastic film. The stacking device 30 is used to control the height of the stacked mobile phone cases for the film feeding device 20 to laminate the film. By adopting the method of using the film feeding device 20 to feed the film and the cooperation of the stacking device 30 with the stacking device (it should be noted that there may be an error in the text here, assuming it is a typo and still referring to the cooperation of the stacking device 30), for the film feeding device 20 to laminate the film, it is beneficial to realize the automatic lamination and stacking of the mobile phone cases, which can effectively reduce the intervention of manual labor in the lamination and stacking of the mobile phone cases, thereby effectively controlling the yield rate of the lamination and stacking of the mobile phone cases, and achieving the purpose of improving the packing efficiency and packing yield rate of the mobile phone cases.

[0040] Below, in combination withFigures 1 to 5 , a further description of the above laminating machine 100 will be given.

[0041] As Figure 1 shown, the frame 10 includes a frame body 11, a placement table 12 and a blanking mechanism 13. As Figure 2 shown, the frame body 11 is provided with a stacking space 111, a stacking position 112, a pulling position 113 and a target position 114. Among them, the stacking space 111 is used to provide space for the stacking device 30 to move, so as to store the mobile phone cases after lamination and stacking. The stacking position 112 is used for placing the mobile phone cases. The mobile phone cases can be placed manually or by a manipulator. By using the manipulator placement method, the control of efficiency, accuracy and yield rate is more precise. The pulling position 113 and the target position 114 are respectively arranged on the opposite sides of the stacking position 112. The distance between the pulling position 113 and the target position 114 is correspondingly set according to the length of the plastic film. That is, by controlling the distance between the pulling position 113 and the target position 114, the length of the plastic film covering the mobile phone case can be effectively controlled. An outlet 115 communicating with the stacking space 111 is provided on the side wall of the frame body 11. The placement table 12 is correspondingly arranged at the outlet 115. The blanking mechanism 13 is installed at the placement table 12. The blanking mechanism 13 is a conveyor. The mobile phone cases after lamination and stacking in the stacking space 111 can be sent out of the frame 10 through the outlet 115 by the blanking mechanism 13 and enter the next process.

[0042] As Figures 2 to 4 shown, the film feeding device 20 includes a material storage mechanism 21, a cutting mechanism 22, a displacement driving mechanism 23, a clamping mechanism 24 and a pressing mechanism 25. Among them, as Figure 2 shown, the material storage mechanism 21 is installed on the frame 10 and is used to provide the plastic film to the pulling position 113. The cutting mechanism 22 is installed at the pulling position 113. The displacement driving mechanism 23 is used to drive the clamping mechanism 24 to reciprocate between the pulling position 113 and the target position 114. The pressing mechanism 25 is installed at the pulling position 113 and is used to fix the plastic film at the pulling position 113 for the cutting mechanism 22 to cut.

[0043] Specifically, as Figure 3 shown, the material storage mechanism 21 includes a material roller 211, a guiding roller 212 and a tensioning plate 213. The material roller 211 is rotatably connected to the frame 10 and is used to install the plastic film coil. The guiding roller 212 is arranged at an interval from the material roller 211 and is used to guide the plastic film to be conveyed to the pulling position 113. One end of the tensioning plate 213 is connected to the frame 10. The other end of the tensioning plate 213 extends between the material roller 211 and the guiding roller 212 and is used to apply a pressing force on the plastic film. When the plastic film is subjected to the pulling force from the pulling position 113 to the target position 114, the situation of excessive feeding of the plastic film can be effectively reduced, thereby improving the feeding accuracy of the plastic film.

The cantilever 241 is connected to the displacement driving mechanism 23. The material clamping driving member 242 is a pneumatic clamping finger 243 and is connected to the cantilever 241. The number of the clamping fingers 243 is two. The material clamping driving member 242 drives the two clamping fingers 243 to approach or move away from each other. The number of the material clamping driving members 242 is at least two, and at least two material clamping driving members 242 are arranged at intervals. The number of the clamping fingers 243 is correspondingly set according to the number of the material clamping driving members 242.

[0046] As shown Figure 4 in Figure 4 , the material pressing mechanism 25 includes a material feeding plate 251, a pressing plate 252 and a material pressing driving member 253. The material feeding plate 251 is connected to the frame 10. The pressing plate 252 and the material feeding plate 251 are spaced apart to form a material feeding port 254 for the plastic film to pass through. The material pressing driving member 253 is a cylinder and is installed on the frame 10 and drives the pressing plate 252 to approach or move away from the material feeding plate 251.

[0047] As shown Figure 2 in Figure 2 , the stacking device 30 includes a stacking platform 31 and a lifting driving mechanism 32. The stacking platform 31 is arranged in the stacking space 111. The lifting driving mechanism 32 drives the stacking platform 31 to approach or move away from the stacking position 112. Specifically, the stacking platform 31 is a conveyor, and the lifting driving mechanism 32 drives the stacking platform 31 to reciprocate between the stacking position 112 and the placing table 12.

[0048] The working steps of the film laminating machine 100 according to the present utility model are as follows:

[0049] Step 1: The lifting driving mechanism 32 of the stacking device 30 drives the stacking platform 31 in the stacking space 111 to move to the stacking position 112;

[0050] Step 2: Place the mobile phone case on the stacking platform 31;

[0051] Step 3: The displacement driving mechanism 23 of the film feeding device 20 drives the material clamping mechanism 24 to move to the material pulling position 113, clamps the plastic film provided by the material storage mechanism 21 to the material pulling position 113 through the material clamping mechanism 24, and the displacement driving mechanism 23 drives the material clamping mechanism 24 to pull the plastic film to the target position 114;

[0052] Step 4: The cutting mechanism 22 cuts the plastic film in Step 3 so that the plastic film covers each mobile phone case.

[0053] Step 5: The lifting drive mechanism 32 drives the stacking platform 31 to descend a predetermined distance, so that the plastic film covering each mobile phone case is at the stacking position 112 for placing the mobile phone cases.

[0054] Steps 2 to 5 are reciprocated in sequence to achieve the packaging operation of the mobile phone cases.

[0055] The beneficial effects of the film laminating machine 100 of the present utility model are as follows: By using the film feeding device 20 to output and control the conveying length of the plastic film, and the lifting drive mechanism 32 of the stacking device 30 drives the stacking platform 31 to approach or move away from the stacking position 112, it is beneficial to realize the automatic film laminating and film stacking of the mobile phone cases through the cooperation of the film feeding device 20 and the stacking device 30, which can effectively reduce the intervention of manual film laminating and film stacking of the mobile phone cases, thereby effectively controlling the yield rate of film laminating and film stacking of the mobile phone cases, and achieving the purpose of improving the packing efficiency and packing yield rate of the mobile phone cases.
