Description

Technical Field

[0001] The utility model relates to the field of die-cutting and printing, in particular to a packaging bag die-cutting machine. Background Art

[0002] The printing die-cutting device is a device that uses a die-cutting knife, a steel knife, a hardware mold, and a steel wire to apply a certain pressure to the die-cutting plate to cut the printed product or cardboard into a certain shape. In the prior art, the printing die-cutting device usually uses a conveyor belt and a die-cutting plate to complete the die-cutting operation. Specifically, the conveyor belt conveys the film (i.e., the packaging bag film) in a step-by-step manner, and then the printing die-cutting device performs pressure cutting after the film stops. However, there are certain defects in the above process: for example, when the film is conveyed by the conveyor belt, its surface may be contaminated with dust or impurities, which may cause interference when the die-cutting plate contacts the film, resulting in poor die-cutting effect.

[0003] Therefore, a packaging bag die-cutting machine is needed to improve the die-cutting effect. Utility Model Content

[0004] The utility model aims to provide a packaging bag die-cutting machine, which can clean the part of the coating film that needs to be pressed and cut in advance, so as to improve the die-cutting effect.

[0005] In order to solve the above technical problems, the utility model provides a packaging bag die-cutting machine, including a support frame, a conveyor belt, a die-cutting plate, and a cleaning component;

[0006] The conveyor belt and the die-cutting plate are both arranged in the support frame, and the die-cutting plate is located directly above the conveyor belt, and the die-cutting plate can move in a direction toward the conveyor belt;

[0007] The cleaning member is arranged on one side of the die-cutting plate;

[0008] The cleaning member comprises a cleaning roller, which is rollably mounted inside the support frame in a direction perpendicular to the conveying direction of the conveyor belt and is capable of contacting the coating on the upper surface of the conveyor belt;

[0009] When the die cutting plate moves, the cleaning roller can be pulled to roll on the coating surface.

[0010] Furthermore, the cleaning member further comprises two deflection plates staggered and arranged in an X shape;

[0011] One end of the two deflection plates is hinged to the die-cutting plate through a rotating shaft, and the other end is rotatably connected to the cleaning roller;

[0012] The two cleaning rollers abut against each other.

[0013] Furthermore, when the cleaning roller is pressed down to contact the coating and the die-cutting plate is continuously pressed down, the deflection plate is pulled to deflect, so that the two cleaning rollers roll in opposite directions to clean the coating.

[0014] Furthermore, when the die-cutting plate is pressed down to complete die-cutting with the laminating film, the deflection plate can be deflected to overlap with the side wall of the die-cutting plate.

[0015] Furthermore, a torsion spring is sleeved on the outer wall of the rotating shaft;

[0016] When the die-cutting plate completes die-cutting and moves in a direction away from the conveyor belt, the torsion spring pulls the deflection plate to reset, so that the two cleaning rollers roll in a direction approaching each other to clean the coating, until the cleaning rollers are separated from the coating.

[0017] Furthermore, the cleaning roller and the deflection plate are detachably connected together.

[0018] Furthermore, a limiting column is rotatably installed on one side of the deflection plate;

[0019] The cleaning roller is fixedly connected to the limiting column.

[0020] Furthermore, one end of the limiting column away from the deflection plate is provided with a thread;

[0021] One end of the cleaning roller is provided with a thread groove matching the limiting column.

[0022] Furthermore, the cleaning roller is made of elastic material.

[0023] Compared with the prior art, the utility model has at least the following beneficial effects:

[0024] By providing a cleaning roller that can roll in a direction perpendicular to the conveying direction of the conveyor belt and can contact the surface of the film, and connecting the cleaning component including the cleaning roller to the die-cutting plate, and moving the die-cutting plate, the cleaning roller can be pulled to roll on the surface of the film, so that when the die-cutting plate is die-cutting the film, the cleaning roller can be controlled to clean the next part of the film that needs to be die-cut at the same time, thereby effectively preventing the occurrence of poor die-cutting effect due to the presence of impurities or dust on the surface of the film.

[0030] The packaging bag die-cutting machine of the utility model will be described in more detail below in conjunction with the schematic diagram, wherein the preferred embodiment of the utility model is shown. It should be understood that those skilled in the art can modify the utility model described herein and still achieve the beneficial effects of the utility model. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the utility model.

[0031] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0032] like Figures 1 to 4 As shown, an embodiment of the utility model provides a packaging bag die-cutting machine, including a support frame 1, a conveyor belt 2, a die-cutting plate 3 and a cleaning component 4.

[0033] Among them, the conveyor belt 2 and the die-cutting board 3 are both arranged in the support frame 1, and the die-cutting board 3 is located directly above the conveyor belt 2, and the die-cutting board 3 can move in the direction toward the conveyor belt 2, that is, the die-cutting board 3 can die-cut with the film on the upper surface of the conveyor belt 2 to realize the die-cutting function.

[0034] The die-cutting board 3 can be controlled by an electric telescopic rod to achieve the function of moving toward the conveyor belt 2 or away from the conveyor belt 2.

[0035] The cleaning component 4 is arranged on one side of the die-cutting plate 3. Specifically, the cleaning component 4 and the die-cutting plate 3 are arranged in sequence along the conveying direction of the conveyor belt 2, so that when the die-cutting plate 3 is die-cutting the coating, the cleaning component 4 can clean the next coating part that needs to be die-cut, effectively avoiding the occurrence of poor subsequent die-cutting effects due to the influence of impurities or dust.

[0036] The cleaning component 4 includes a cleaning roller 41 , which is rollingly installed inside the support frame 1 along a direction perpendicular to the conveying direction of the conveyor belt 2 and can contact the coating on the upper surface of the conveyor belt 2 .

[0037] In addition, when the die cutting board 3 moves, it can pull the cleaning roller 41 to roll on the coating surface.

[0038] The device is provided with a cleaning roller 41 which can roll in a direction perpendicular to the conveying direction of the conveyor belt 2 and can contact the surface of the film, and the cleaning component 4 including the cleaning roller 41 is connected to the die-cutting plate 3, and when the die-cutting plate 3 moves, the cleaning roller 41 can be pulled to roll on the surface of the film, so that when the die-cutting plate 3 is die-cutting the film, the cleaning roller 41 can be controlled to clean the next part of the film to be die-cut, thereby effectively preventing the occurrence of poor die-cutting effect due to the presence of impurities or dust on the surface of the film.

[0039] In this embodiment, the cleaning component 4 is further defined so that when the die-cutting board 3 moves, the cleaning roller 41 can be better controlled to clean the coating.

[0040] Specifically, the cleaning component 4 further includes two deflection plates 42 which are staggered and arranged in an X shape.

[0041] One end of the two deflection plates 42 is hinged to the die-cutting board 3 through a rotating shaft, and the other end is rotatably connected to the cleaning roller 41, and the two cleaning rollers 41 abut against each other. When the cleaning roller 41 is pressed down to contact the coating and the die-cutting board 3 is continuously pressed down, the deflection plates 42 are pulled to deflect, thereby controlling the two cleaning rollers 41 to roll in opposite directions to clean the coating.

[0042] It should also be noted that a torsion spring is provided on the outer wall of the rotating shaft, so that when the die-cutting plate 3 completes die-cutting and moves in the direction away from the conveyor belt 2, the torsion spring pulls the deflection plate 42 to reset, so that the two cleaning rollers 41 roll in a direction approaching each other to clean the film until the cleaning rollers 41 are separated from the film, that is, a second cleaning can be achieved, further improving the cleaning effect of the film.

[0043] In other embodiments, the positional relationship between the die-cutting plate 3 and the deflection plate 42 is further limited so that the arrangement of the deflection plate 42 does not interfere with the die-cutting function of the die-cutting plate 3 .

[0044] Specifically, when the die-cutting plate 3 is pressed down to complete die-cutting with the coating, the deflection plate 42 can be deflected to overlap with the side wall of the die-cutting plate 3, so that when the die-cutting plate 3 is attached to the coating and the die-cutting operation is performed, the deflection plate 42 will not interfere with the movement of the die-cutting plate 3.

[0045] In other embodiments, in order to facilitate regular replacement or cleaning of the cleaning roller 41 , the cleaning roller 41 and the deflection plate 42 are detachably connected together.

[0046] Among them, a limiting column 421 is rotatably installed on one side of the deflection plate 42, and the cleaning roller 41 is fixedly connected to the limiting column 421, so that the cleaning roller 41 can rotate relative to the deflection plate 42. Therefore, when the deflection plate 42 is deflected and the cleaning roller 41 contacts the coating, a rolling cleaning operation can be performed.

[0047] In addition, in order to facilitate the connection between the limiting column 421 and the cleaning roller 41, a thread is set at one end of the limiting column 421 away from the deflection plate 42, and a thread groove matching the limiting column 421 is set at one end of the cleaning roller 41. The thread groove and the threaded end of the limiting column 421 are used to fix the cleaning roller 41 and the limiting column 421.

[0048] In other embodiments, in order to prevent the cleaning roller 41 from damaging the coating, the cleaning roller 41 is also made of elastic material.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
