Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, and not all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0024] Refer to Figures 1-4, An upper film device of a laminating machine, including a frame body 1. A conveyor belt 3 is provided between the inner walls on both sides of the frame body 1. Slide holes 7 penetrating the frame body 1 are opened on the outer walls on both sides of the frame body 1. Plug racks 2 are slidably connected in both slide holes 7. A first tension spring 8 is fixed to one side of the plug rack 2 by bolts, and the first tension spring 8 is fixed to the frame body 1. The first tension spring 8 can pull the plug rack 2 to slide towards the frame body 1 and keep the plug rack 2 in this position. A power mechanism for driving the plug rack 2 to move is provided at the top of the frame body 1. A winding roller 11 is provided between the two plug racks 2, and the two plug racks 2 are respectively inserted into both ends of the winding roller 11. A film is wound around the circumferential outer wall of the winding roller 11. A support frame 5 is slidably connected to the inner bottom wall of the frame body 1, and the support frame 5 is in contact with the film. A pull frame 16 is fixed to one side of the support frame 5 by bolts, and one end of the pull frame 16 passes through the frame body 1 and is slidably connected to the frame body 1. The support frame 5 can be pulled to move by pulling the pull frame 16 to change the position of the support frame 5. Two stop frames 6 are welded to the inner bottom wall of the frame body 1, and the two stop frames 6 are symmetrically distributed. The two stop frames 6 can position the position of the support frame 5. When the support frame 5 contacts the stop frames 6, the winding roller 11 can be installed or disassembled. A placement groove 4 for storing multiple winding rollers 11 is provided at one end of the frame body 1. A blocking mechanism for supporting the winding roller 11 is provided at the bottom of the placement groove 4. By the power mechanism, the fixing of the plug rack 2 to the winding roller 11 is released, and the winding roller 11 can be disassembled. After disassembling the winding roller 11, pull the pull frame 16 to move leftward. The pull frame 16 will drive the support frame 5 to move rightward, thereby squeezing the blocking mechanism, causing the blocking mechanism to release the support for the winding roller 11, and then the winding roller 11 in the placement groove 4 will fall onto the support frame 5. Push the pull frame 16 to move rightward so that the support frame 5 contacts the stop frames 6. At this time, the hole grooves on both sides of the winding roller 11 on the support frame 5 are aligned with the plug racks 2. Without holding the winding roller 11 by hand, the positioning of the winding roller 11 can be completed. Then, the winding roller 11 is limited by the power mechanism, and the replacement of the winding roller 11 is completed, improving the labor-saving property of the device for replacing the film roll.

[0025] In the present utility model, the power mechanism includes two jacks 9. Both jacks 9 are opened at the top of the frame body 1, and the two jacks 9 communicate with the slide holes 7. Positioning frames 10 are slidably connected in both jacks 9. One side of the bottom end of the positioning frame 10 is an inclined surface. Slots 17 are opened at the tops of both plug racks 2, and the positioning frames 10 can be inserted into the slots 17. Press the positioning frame 10, and the inclined surface of the positioning frame 10 will squeeze the slot 17, causing the plug rack 2 to slide outwards. When the positioning frame 10 completely enters the slot 17, the plug rack 2 is disengaged from the winding roller 11, thereby completing the release of the fixing of the winding roller 11.

[0026] Among them, the blocking mechanism includes a sliding opening which is penetrated and formed on one side of the frame body 1. A sliding frame 15 is slidably connected in the sliding opening. A second tension spring 13 is fixed to the inner wall of one side of the sliding frame 15 by bolts, and the second tension spring 13 is fixed to the frame body 1. A blocking block 12 is fixed to the inner wall of the bottom of the sliding frame 15 by bolts. An avoidance groove 14 is formed on the inner wall of one side of the frame body 1, and the blocking block 12 can be inserted into the avoidance groove 14. The winding roller 11 in the placement groove 4 is supported by the sliding frame 15, and the blocking block 12 abuts against the bottommost winding roller 11. When the support frame 5 moves over, the winding roller 11 can directly fall on the support frame 5. During the process of the support frame 5 sliding to the left, it will squeeze the sliding frame 15 to move to the left. The movement of the sliding frame 15 drives the movement of the blocking block 12, which will squeeze the winding roller 11 to move upward. When the support frame 5 continues to move to the left, the blocking block 12 will enter the avoidance groove 14, so that the winding roller 11 enters above the support frame 5. Pushing the support frame 5 to move to the right, the reset of the stretched and deformed second tension spring 13 will drive the sliding frame 15 to reset, thus restoring the original state. Under the action of gravity, the winding roller 11 located in the placement groove 4 slides downward and is blocked by the blocking block 12 again.

[0027] Working principle: When the roll needs to be replaced, press the positioning frame 10. The inclined surface of the positioning frame 10 will squeeze the insertion slot 17, so that the insertion frame 2 slides outward. When the positioning frame 10 completely enters the insertion slot 17, the insertion frame 2 is separated from the winding roller 11, thus completing the release of the fixation of the winding roller 11. Then the winding roller 11 is disassembled. After disassembling the winding roller 11, pull the pulling frame 16 to move to the left. The pulling frame 16 will drive the support frame 5 to move to the right. When the support frame 5 slides to the left, it will squeeze the sliding frame 15 to move to the left. The movement of the sliding frame 15 drives the movement of the blocking block 12, which will squeeze the winding roller 11 to move upward. When the support frame 5 continues to move to the left, the blocking block 12 will enter the avoidance groove 14, so that the winding roller 11 enters above the support frame 5. Pushing the support frame 5 to move to the right, the reset of the stretched and deformed second tension spring 13 will drive the sliding frame 15 to reset, thus restoring the original state. Under the action of gravity, the winding roller 11 located in the placement groove 4 slides downward and is blocked by the blocking block 12 again. When the support frame 5 contacts the blocking frame 6, the hole slots on both sides of the winding roller 11 on the support frame 5 are aligned with the insertion frame 2. Without manually holding the winding roller 11, the positioning of the winding roller 11 can be completed. Then, the winding roller 11 is limited by the power mechanism, and the replacement of the winding roller 11 is completed.

[0028] Finally, it should be noted that: For those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
