Description

Technical Field

[0001] The present invention relates to the technical field of film cutting, and in particular to a film cutting mechanism of a film laminating machine. Background Art

[0002] The film laminating machine is used to apply mobile phone films to the screens of mobile phones, tablets and other electronic products for protection. With the gradual development of protective films, they have been transformed from tempered films to softened protective films, which can not only better fit the curved screen, but also achieve better impact absorption.

[0003] The application of film laminating machines makes it possible to apply protective films in batches. Similarly, a large number of protective films are required, so corresponding film cutting mechanisms need to be equipped.

[0004] For the cutting of softened protection, the existing technology mostly adopts die-cutting, which can not only simplify the cutting path, but also make the edges and corners of the softened film smoother after cutting. However, in the existing die-cutting mechanism, the cut film has a certain hardness, which will be stuck in the inner cavity of the die and cannot be discharged reliably.

[0005] To this end, the present invention provides a film cutting mechanism for a film laminating machine. Summary of the invention

[0012] Furthermore: the eccentric angle of the eccentric wheel 1 is located downstream of the eccentric angle of the eccentric wheel 2 relative to the rotation direction.

[0013] On the basis of the above scheme: one end of the shaft 1 is fixed with an end plate by bolts, a torsion spring is buckled on the side wall of the end plate, and the other end of the torsion spring is buckled on the side wall of the frame.

[0014] A better solution in the above solution is: a reel is fixed to the other end of the shaft 1, slides are fixed to both sides of the lifting seat, and a slide groove that slidably cooperates with the slide is opened on the inner wall of the frame.

[0016] At the same time, a connecting rope is wound around the outer wall of the reel, and the other end of the connecting rope is fixed to the bottom outer wall of the sliding frame.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention, on the basis of realizing "die cutting" by using a punch and a die, adds a push rod, and utilizes the delayed movement of the push rod relative to the die to eject the protective film that may be stuck on the inner wall of the die and drop it to the top of the punch, thereby realizing reliable material discharge.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] Embodiment 1:

[0038] A film cutting mechanism of a film laminating machine, such as Figure 1-Figure 8 As shown, it includes a frame 1, and a winding roller 3 and an unwinding roller 2 are respectively arranged on the upper and lower inner sides of one end of the frame 1, and the winding roller 3 and the unwinding roller 2 are both rotatably connected to the frame 1 through a roller shaft 4, and one end of the two roller shafts 4 are matched through a belt drive or a gear drive, and when the unwinding roller 2 rotates to unwind, the winding roller 3 is rotationally wound, and a cutting component 5 is arranged on the inner side of the frame 1, and a linkage driving component 7 for driving the roller shaft 4 and the slide 25 is arranged on the side wall of the frame 1, and a guide roller 9 is rotatably connected to the inner side of the other end of the frame 1 through a guide shaft 10, and the protective film unwound by the unwinding roller 2 is wound around the guide roller 9 and then wound up by the winding roller 3.

[0039] The cutting assembly 5 includes a punch 11 and a die 14 that cooperate with each other. The bottom of the punch 11 is fixed with a rotating seat 12 by bolts, and the rotating seat 12 is rotatably connected to the inner side of the frame 1 through an axis 13. The top of the die 14 is fixed with a lifting seat 15 by bolts, and the inner wall of the lifting seat 15 is slidably connected with a push rod 16, and the tops of the lifting seat 15 and the push rod 16 are provided with a lifting drive 8 for lifting drive.

[0040] When the device is in use, the flexible protective film wound on the unwinding roller 2 is pulled open, passed around the guide roller 9 and then fixed to the outer wall of the winding roller 3. When the lifting drive 8 is started, it can drive the lifting seat 15 and the push rod 16 to rise and fall, and the lifting position of the push rod 16 is delayed from the lifting position of the lifting seat 15. When the lifting seat 15 descends, it can cooperate with the punch 11 to cut the protective film. After cutting, due to the delay of the push rod 16, the push rod 16 is still in the descending stage at the initial stage of the lifting of the lifting seat 15, so that the protective film that may be stuck on the inner wall of the die 14 can be ejected and dropped to the top of the punch 11, until the die 14 is completely reset, the unwinding roller 2 and the winding roller 3 rotate synchronously again, respectively unwinding and winding up the waste, and completing one working step.

[0041] This device, based on the use of the punch 11 and the die 14 to achieve "die cutting", is additionally provided with a push rod 16. By utilizing the delayed movement of the push rod 16 relative to the die 14, the protective film that may be stuck on the inner wall of the die 14 can be ejected and dropped to the top of the punch 11, thereby achieving reliable material discharge.

[0042] To solve the driver problem; Figure 3 As shown, the lifting drive member 8 includes an eccentric wheel 18 and an eccentric wheel 20. The eccentric wheel 18 and the eccentric wheel 20 are fixed with a same wheel axle 21 at non-geometric centers. The wheel axle 21 is rotatably connected to the inner side of the frame 1. The outer wall of the eccentric wheel 18 is rotatably connected to an eccentric sleeve 17. The end of the eccentric sleeve 17 is rotatably connected to the top outer wall of the push rod 16. The outer wall of the eccentric wheel 20 is rotatably connected to an eccentric sleeve 29. The end of the eccentric sleeve 29 is rotatably connected to the top outer wall of the lifting seat 15.

[0043] Furthermore, the eccentric angle of the eccentric wheel 18 is located downstream of the eccentric angle of the eccentric wheel 20 relative to the rotation direction.

[0044] When the wheel shaft 21 rotates, it can drive the eccentric wheel 18 and the eccentric wheel 20 to rotate, thereby driving the lifting seat 15 and the push rod 16 to rise and fall through the eccentric sleeve 17 and the eccentric sleeve 2 19, and because the eccentric angle of the eccentric wheel 18 is located downstream of the eccentric angle of the eccentric wheel 20 relative to the rotation direction, the lifting movement of the push rod 16 is delayed compared with the lifting seat 15 during synchronous rotation.

[0045] This device, based on the "eccentric" lifting drive, controls the angles of the eccentric wheel 18 and the eccentric wheel 20, which can meet the lifting sequence requirements of the lifting seat 15 and the push rod 16 on the one hand, and can also drive the lifting of the lifting seat 15 and the push rod 16 in a comprehensive and synchronous manner on the other hand, thereby reducing the power source layout and increasing the linkage.

[0046] In order to solve the problem of cutting materials; Figure 3 As shown, one end of the shaft 13 is fixed with an end plate 22 by bolts, a side wall of the end plate 22 is buckled with a torsion spring 23, and the other end of the torsion spring 23 is buckled with the side wall of the frame 1.

[0047] A reel 26 is fixed to the other end of the shaft 13 , slides 24 are fixed to both sides of the lifting seat 15 , and a slide groove 25 slidably matched with the slides 24 is formed on the inner wall of the frame 1 .

[0048] The side wall of the frame 1 is longitudinally slidably connected with a slide plate 29, the top of the slide plate 29 is slidably connected to the inner wall of the slide 24, and the outer wall of the slide plate 29 is buckled with a spring 31, the other end of the spring 31 is buckled with the bottom outer wall of the slide 24, the outer wall of the reel 26 is provided with a tooth groove 27, and the bottom outer wall of the slide plate 29 is fixed with a tooth block 28 that engages with the tooth groove 27.

[0049] The longitudinal section of the slide plate 29 is in an I-shape.

[0050] A connecting rope 30 is wound around the outer wall of the reel 26 , and the other end of the connecting rope 30 is fixed to the bottom outer wall of the sliding bracket 24 .

[0051] A collection box 6 is placed inside the frame 1 .

[0052] When the lifting seat 15 descends, it will drive the slide 24 to descend synchronously, so that the tooth block 28 and the slide plate 29 descend. During this process, the connecting rope 30 is relaxed, and the shaft 13 rotates under the torsion of the torsion spring 23 until the punch 11 rotates to a horizontal state, the tooth block 28 engages with the tooth groove 27, and as the slide plate 29 continues to descend, the reel 26 cannot rotate, the connecting rope 30 will gradually relax, and then the cutting operation is performed. After the cutting operation is reset, the slide 24 rises until the slide 24 drives the slide plate 29 to rise until the tooth groove 27 is disengaged from the tooth block 28, the connecting rope 30 is straightened, and the slide 24 continues to rise and reset. The reel 26 can be driven to rotate by the connecting rope 30, thereby driving the punch 11 to rotate and tilt through the shaft 13, and guiding the protective film that falls to the top of the punch 11 to fall into the collection box 6 for collection.

[0053] This device, by providing a rotatable punch 11, can use the rotation of the punch 11 to unload materials after cutting is completed, and collect the cut protective films in a centralized manner. At the same time, by providing components such as a reel 26 and a connecting rope 30, it can use the lifting and lowering of the slide 24 to drive the punch 11 to rotate, realizing power integration and motion synchronization, and can also lock the punch 11 during the cutting process to ensure die-cutting reliability.

[0054] When the present embodiment is in use, the flexible protective film wound on the unwinding roller 2 is pulled open, passed around the guide roller 9 and then fixed to the outer wall of the winding roller 3. When the lifting drive 8 is started, it can drive the lifting seat 15 and the push rod 16 to rise and fall, and when the wheel shaft 21 rotates, it can drive the eccentric wheel 18 and the eccentric wheel 20 to rotate, thereby driving the lifting seat 15 and the push rod 16 to rise and fall through the eccentric sleeve 17 and the eccentric sleeve 21. Since the eccentric angle of the eccentric wheel 18 is located downstream of the eccentric angle of the eccentric wheel 20 relative to the rotation direction, during synchronous rotation, the lifting movement of the push rod 16 is delayed from the lifting seat 15. When the lifting seat 15 descends, it can cooperate with the punch 11 to cut the protective film. After cutting, due to the delay of the push rod 16, the push rod 16 is still in the descending stage at the initial stage of the lifting seat 15 rising, thereby the protective film that may be stuck on the inner wall of the die 14 can be ejected and dropped to the top of the punch 11 until the die 14 is completely reset. , the unwinding roller 2 and the winding roller 3 rotate synchronously again, unwinding and winding the waste material respectively, completing a working step, and when the lifting seat 15 descends, it will drive the slide 24 to descend synchronously, so that the tooth block 28 and the slide plate 29 descend. In this process, the connecting rope 30 is relaxed, and the shaft 13 is rotated by the torsion of the torsion spring 23 until the punch 11 rotates to a horizontal state, the tooth block 28 is engaged with the tooth groove 27, and as the slide plate 29 continues to descend, the reel 26 cannot rotate, the connecting rope 30 will gradually relax, and then the cutting operation is performed. After the cutting operation is reset, the slide 24 rises with it until the slide 24 drives the slide plate 29 to rise until the tooth groove 27 is disengaged from the tooth block 28, the connecting rope 30 is straightened, and the slide 24 continues to rise and reset, and the reel 26 can be driven to rotate by the connecting rope 30, thereby driving the punch 11 to rotate and tilt through the shaft 13, and guiding the protective film that falls to the top of the punch 11 to fall into the collection box 6 for collection.

[0055] Embodiment 2:

[0056] A film cutting mechanism of a film laminating machine, such as Figure 7 , 8As shown, in order to solve the problem of comprehensive driving and synchronization; this embodiment makes the following improvements on the basis of embodiment 1: the linkage drive component 7 includes two rotating frames 37, a base plate 32 and a limit plate 38, one of the rotating frames 37 is fixed to the outer wall of the roller shaft 4, and the other rotating frame 37 is matched with the outer wall of the wheel shaft 21 through the acceleration component transmission, the base plate 32 is coaxially fixed with the limit plate 38, and they are both rotatably connected to the side wall of the frame 1.

[0057] In this embodiment, the specific type of the acceleration component is not limited, and is preferably a planetary gear set.

[0058] The side wall of the rotating frame 37 is provided with a plurality of strip grooves 36, the side wall of the base plate 32 is fixed with a driving column 33 that cooperates with the strip grooves 36, the outer wall of the rotating frame 37 is provided with a limiting notch 35 that cooperates with the limiting plate 38, and the side wall of the limiting plate 38 is provided with a rotation avoidance notch 34 for avoiding the rotation of the rotating frame 37.

[0059] A motor 39 is fixed to the side wall of the frame 1 through a motor frame 40 , and an output shaft of the motor 39 is fixed to the rotation center of the limiting plate 38 .

[0060] When the present embodiment is in use, when the motor 39 is started, it can drive the limit plate 38 to rotate. First, the limit plate 38 will rotate to the rotating frame 37 connected to the roller shaft 4. At this time, the driving column 33 is inserted into the inner wall of the strip groove 36. The strip groove 36 drives the rotating frame 37 to rotate, thereby driving the roller shaft 4 to rotate to realize the transportation of the protective film. After the transportation is completed, the limiting notch 35 of the rotating frame 37 cooperates with the outer wall of the limiting plate 38 to limit the rotation of the rotating frame 37. As the driving column 33 rotates to another rotating frame 37, it drives the other rotating frame 37 to rotate, thereby driving the wheel axle 21 to rotate through the acceleration component, so that the wheel axle 21 rotates one circle for die cutting.

[0061] The present device, by setting up a linkage drive assembly 7, utilizes a "double intermittent" transmission, which can simultaneously and successively convey and die-cut the protective film on the one hand, and can lock "the other" when driving "one", thereby preventing both cutting defects caused by the movement of the protective film during die-cutting and scratches caused by the movement of the conveying to the die-cutting component.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
