[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification and the foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification or the foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.
[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0024] This utility model provides an automatic film feeding device for a die-cutting machine, such as... Figure 1-6 As shown, the automatic film feeding device for the die-cutting machine includes: a die-cutting machine body 1, with a control screen on the top of the die-cutting machine body 1; a support plate 2 fixedly installed at the bottom of the die-cutting machine body 1, with a bottom shell 3 below the support plate 2, and a box 4 fixedly installed on one side of the bottom shell 3; and an automatic film feeding mechanism assembled on the box 4 for feeding protective film into the die-cutting machine body 1.
[0025] In this design, before use, the device can store a large number of stacked protective films on the placement plate 7 of the automatic film feeding mechanism. Each time a protective film needs to be fed into the die-cutting machine body 1, simply activating the automatic film feeding mechanism will automatically feed the top layer of protective film into the die-cutting machine body 1. After feeding, the die-cutting machine body 1 can be activated to cut the protective film. The die-cutting machine body 1 is based on existing mature technology, and its principle will not be described in detail here. During the cutting process, the product to be covered can be cleaned. After the protective film is cut, it can be immediately applied to the display screen of the corresponding product. The automatic film feeding mechanism effectively saves operators the time spent searching for, removing, and inserting protective films into the die-cutting machine body 1, making the use of the die-cutting machine body 1 more convenient.
[0026] In a further preferred embodiment of this utility model, the automatic film feeding mechanism includes: a box 5 disposed within the housing 4, a spring 6 fixedly installed on the bottom inner wall of the box 5, and a placement plate 7 for storing protective film fixedly installed on the spring 6; a support frame 8 fixedly installed on the top inner wall of the housing 4, a rotating shaft 9 rotatably installed on the support frame 8, a push wheel 10 fixedly sleeved on the rotating shaft 9, and a rubber ring 11 for pushing the protective film fixedly sleeved on the push wheel 10; a servo motor 12 fixedly installed on the top inner wall of the housing 4, a first sprocket 13 fixedly sleeved on the output shaft of the servo motor 12; a second sprocket 14 fixedly sleeved on the rotating shaft 9; a chain 15 sleeved on the first sprocket 13 and the second sprocket 14; and a discharge port 16 opened on the housing 4.
[0027] In this embodiment, the automatic film feeding mechanism is used to feed protective film into the die-cutting machine body 1. When protective film needs to be fed into the die-cutting machine body 1, the servo motor 12 is started. The servo motor 12 drives the first sprocket 13 to rotate. The first sprocket 13 drives the second sprocket 14 to rotate through the chain 15. The second sprocket 14 drives the rotating shaft 9 to rotate on the support frame 8. The rotating shaft 9 drives the push wheel 10 to rotate, so that the rubber ring 11 on the push wheel 10 can push the top protective film placed on the placement plate 7, so that the top protective film can be pushed out from the discharge port 16 and then automatically enter the die-cutting machine body 1. The film feeding is relatively convenient. After the film feeding operation is completed, the spring 6 will push the placement plate 7 upward through its own elasticity until the next protective film to be cut contacts the rubber ring 11, so that the next film feeding operation can be performed.
[0028] In a further preferred embodiment of the present invention, the automatic film feeding device of the die-cutting machine further includes a height adjustment mechanism installed on the bottom shell 3 for raising and lowering the die-cutting machine body 1.
[0029] In this embodiment, the height of the die-cutting machine body 1 can be adjusted by using a height adjustment mechanism, so as to facilitate operation when it is necessary to inspect the feed inlet of the die-cutting machine body 1.
[0030] In a further preferred embodiment of the present invention, the height adjustment mechanism includes: a dual-axis motor 17 fixedly installed on the inner wall of the bottom of the bottom shell 3, a screw 18 fixedly installed on the output shaft of the dual-axis motor 17, a slider 19 threadedly installed on the screw 18, a hinge rod 20 hinged to the slider 19, and one end of the hinge rod 20 hinged to the bottom of the support plate 2.
[0031] In this embodiment, when the height adjustment mechanism is in use, the dual-axis motor 17 is started, which drives the screw 18 to rotate. The screw 18 drives the slider 19 to move, and the slider 19 drives the support plate 2 to move vertically through the hinge rod 20. This enables the height adjustment of the die-cutting machine body 1, so that when the die-cutting machine body 1 needs to be repaired, the feed port of the die-cutting machine body 1 can be higher than the top of the box 4 for maintenance operations.
[0032] In a further preferred embodiment of the present invention, an inlet and outlet are provided on one side of the box body 4. The inlet and outlet are located outside the box body 5 and are used for taking out and putting in the box body 5.
[0033] In this embodiment, by using the inlet and outlet, when the protective film inside the box 5 is used up, the box 5 can be easily removed from one side of the box 4 and then the protective film can be replenished.
[0034] In a further preferred embodiment of the present invention, a strip-shaped hole 21 is provided on one side of the box body 5, and a limiting rod 22 is fixedly installed on the inner wall of the strip-shaped hole 21. A pressure plate 23 for pressing down the placement plate 7 is slidably installed on the limiting rod 22, and one side of the pressure plate 23 is fixedly connected to the placement plate 7.
[0035] In this embodiment, by using the strip hole 21, the limiting rod 22 and the pressure plate 23 together, after a large number of stacked protective films are placed on the top of the placement plate 7, the pressure plate 23 can be pressed down by hand, so that the pressure plate 23 drives the placement plate 7 to squeeze the spring 6 and move down, so that the topmost protective film can enter the interior of the box 5. After the placement is completed, the operator can easily insert the box 5 into the box 4 from the inlet and outlet.
[0036] In a further preferred embodiment of the present invention, a telescopic rod 24 for preventing the support plate 2 from tilting is fixedly installed on the bottom inner wall of the bottom shell 3, and the top end of the telescopic rod 24 is fixedly connected to the bottom of the support plate 2.
[0037] In this embodiment, the use of the telescopic rod 24 can prevent the support plate 2 from tilting during lifting. When the support plate 2 is lifted vertically, the telescopic rod 24 connected to it will also extend and retract at the same time. Since the telescopic rod 24 can only extend and retract vertically, it can effectively prevent the support plate 2 from tilting, thereby ensuring the stability of the die-cutting machine body 1.
[0038] In a further preferred embodiment of the present invention, a positioning plate for supporting the screw 18 is fixedly installed on the bottom inner wall of the bottom shell 3, and the positioning plate is rotatably connected to the screw 18.
[0039] In this embodiment, the use of a positioning plate can provide better support for the screw 18, making the screw 18 more stable during rotation.
[0040] In summary, compared with related technologies, the automatic film feeding mechanism in this solution can not only store a large amount of protective film to be used, but also automatically push the top layer of protective film into the die-cutting machine body 1 when it is necessary to feed the protective film into the die-cutting machine body 1. In this way, the operator can be saved from the process of finding, taking out and putting the protective film into the die-cutting machine body 1 each time the protective film is cut, which can save time and make the use of the die-cutting machine body 1 more convenient.
