Description

Technical Field

[0001] The utility model relates to the technical field of pre-coating film production, in particular to a multi-segment cutting device for pre-coating film production. Background Art

[0002] Pre-coating refers to the process of pre-gluing and rewinding plastic film before laminating it with printed paper. The pre-coating factory first applies glue to the film according to the specifications and format, then rewinds it for the manufacturer to select, and then laminates it with the printed matter. Laminating, also known as laminating, involves coating plastic film with adhesive and bonding it to the printed matter through heating and pressure to create a paper-plastic hybrid product. Laminated printed matter has an additional layer of thin, transparent plastic film, resulting in a smoother, brighter surface, improved gloss and durability, and more vivid and three-dimensional images. It also provides waterproofing, stain resistance, abrasion resistance, fold resistance, and chemical resistance.

[0003] A search revealed an existing patent (Announcement No. CN215471345U) that discloses a cutting device for pre-coated film production. The device comprises a cutter positioned at the material cutting position, a first lifting mechanism connected to the cutter for raising and lowering the cutter, two sets of vacuum nozzles positioned on either side of the cutter for sucking up the material, a second lifting mechanism connected to the vacuum nozzles for raising and lowering the nozzles, and a vacuum pump connected to the vacuum nozzles via a pipeline. This utility model utilizes the first lifting mechanism to raise and lower the cutter, and the second lifting mechanism to raise and lower the vacuum nozzles. The coordinated operation of the liftable vacuum nozzles and the cutter allows for rapid cutting of material at the cutting position on a conveyor belt, effectively improving the cutting efficiency of the cutting device.

[0004] However, in the above solution, when the pre-coated film is being transported, the pre-coated film is likely to be displaced on the transmission belt, thereby affecting the entire cutting process. In addition, the device can only cut the pre-coated film at one end, which reduces the cutting efficiency of the pre-coated film.

[0005] In view of this, the utility model proposes a multi-stage cutting device for pre-coating film production. Utility Model Content

[0026] Example 1

[0027] The preferred embodiment of the multi-stage cutting device for pre-coated film production provided by the utility model is as follows Figures 1 to 5As shown: A multi-stage cutting device for pre-coated film production includes a side plate 1, an internal rotation connection of the side plate 1 is connected to a connecting shaft 2, the surface of the side plate 1 is fixedly connected to a motor 3 whose output end is fixedly connected to the connecting shaft 2, the surface of the connecting shaft 2 is tightly fitted with a transmission belt 4, the back of the side plate 1 is fixedly connected to a back plate 6, and a cutting mechanism 7 is provided at the bottom of the back plate 6.

[0028] In this embodiment, the cutting mechanism 7 includes an adjusting component 71 and a cutting component 72. By providing the cutting mechanism 7, the purpose of quickly and multi-segmentally cutting the pre-coated film can be achieved.

[0029] In this embodiment, the adjustment component 71 includes a first electric push rod 711, a lifting plate 712, a connecting groove 713 and an electric suction cup 714. By setting the adjustment component 71, the electric suction cup 714 absorbs the pre-coated film and controls the pre-coated film to rise through the first electric push rod 711 to prepare for cutting.

[0030] In this embodiment, the first electric push rod 711 is fixedly connected to the bottom of the back plate 6 , the output end of the first electric push rod 711 is fixedly connected to the lifting plate 712 , and the bottom of the lifting plate 712 is fixedly connected to the electric suction cup 714 .

[0031] In this embodiment, the cutting assembly 72 includes a second electric push rod 721, a moving block 722, a third electric push rod 723 and a cutting knife 724. The third electric push rod 723 controls the cutting knife 724 to descend through the connecting groove 713 and contact the pre-coated film, and under the action of the second electric push rod 721, the cutting knife 724 is controlled to slide, thereby achieving the purpose of cutting the pre-coated film. By setting multiple groups of cutting knives 724, multiple sections of the pre-coated film can be cut at the same time.

[0032] In this embodiment, the second electric push rod 721 is fixedly connected to the back of the lifting plate 712, the output end of the second electric push rod 721 is fixedly connected to the moving block 722, the bottom of the moving block 722 is fixedly connected to the third electric push rod 723, and the output end of the third electric push rod 723 is fixedly connected to the cutting knife 724 that fits into the connecting groove 713.

[0033] Example 2

[0034] On the basis of Example 1, a preferred embodiment of a multi-stage cutting device for pre-coated film production provided by the present invention is as follows: Figures 1 to 5 As shown: the surface of the side panel 1 is fixedly connected to the mounting plate 5, the interior of the mounting plate 5 is slidingly connected to the transmission rod 9, the surface of the transmission rod 9 is threadedly connected to the nut 10, the tail of the transmission rod 9 is fixedly connected to the limit plate 11 located on the side of the transmission belt 4, one end of the transmission rod 9 is fixedly connected to the connecting plate 8, and the side wall of the connecting plate 8 is fixedly connected to the spring 12 fixedly connected to the mounting plate 5.

[0035] In this embodiment, the bottom of the limit plate 11 fits with the top of the transmission belt 4, and the transmission rod 9 forms a fixed structure inside the mounting plate 5 through the nut 10. By setting the limit plate 11, the limit plate 11 can limit the two ends of the pre-coated film, effectively avoiding the phenomenon of the film being out of position during transmission. Since the width of pre-coated films of different models is different, when the position of the limit plate 11 needs to be adjusted, the nut 10 can be loosened. When the nut 10 is loosened and away from the mounting plate 5, the transmission rod 9 can be quickly pushed forward under the action of the spring 12, so that the nut 10 conflicts with the mounting plate 5 again, thereby completing the purpose of adjusting the limit plate 11.

[0036] The working principle and usage process of the present invention: First, when the device is used, the pre-coated film to be cut is placed on the transmission belt 4, and the motor 3 drives the connecting shaft 2 to rotate, and then drives the transmission belt 4 to move, so that it conveys the pre-coated film. By setting the limit plate 11, the limit plate 11 can limit the two ends of the pre-coated film, effectively avoiding the phenomenon of the film being out of position during transmission, and because the width of pre-coated films of different models is different, when the position of the limit plate 11 needs to be adjusted, the nut 10 can be loosened. When the nut 10 is loosened and away from the mounting plate 5, under the action of the spring 12, the transmission rod 9 can be quickly pushed forward, so that the nut 10 is in conflict with the mounting plate 5 again, thereby completing the purpose of adjusting the limit plate 11.

[0037] When the pre-coated film is conveyed to the bottom of the electric suction cup 714, the transmission belt 4 stops working. At this time, the electric suction cup 714 absorbs the pre-coated film and controls the pre-coated film to rise through the first electric push rod 711 to prepare for cutting. Then, the third electric push rod 723 controls the cutting knife 724 to descend through the connecting groove 713 to contact the pre-coated film, and under the action of the second electric push rod 721, the cutting knife 724 is controlled to slide, so as to achieve the purpose of cutting the pre-coated film. By setting up multiple groups of cutting knives 724, it is possible to cut the pre-coated film in multiple sections at the same time. At this time, the cut pre-coated film will fall on the transmission belt 4 and be transported away when the electric suction cup 714 no longer absorbs it.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
