Description

Technical Field

[0001] The utility model relates to the technical field of film cutting, in particular to a film slitter. Background Art

[0002] Film slitting is widely used in the field of film processing, among which the most prominent representative is the film cutter. Thus, simple film slitting devices based on the film cutter have derived into multiple types, including those with similar configurations to tape cutters. After searching, the Chinese patent publication number CN219296798U discloses a film slitter, including a tube body for entrapping a film tube, the tube body being provided with an elastic contact tube member for pushing the contact tube member to touch the film tube so that the film tube is stationary in the tube body. The utility model is combined with an elastic contact tube member, and the distance from the contact tube member to the film tube is artificially controlled to suppress excessive rotation of the film tube into the tube body.

[0003] Although the above technical solution can prevent the film roll from rotating inside the tube body, the width of the film roll is different during use, while the length of the device is fixed. For a shorter film roll, shaking and the like occur, which makes it inconvenient to fix the film roll. In addition, the cutter in the above technical solution is installed in the telescopic groove. Therefore, after the film is cut, the remaining end will fall back into the inside of the tube body. The tube body needs to be opened again to pull out one end of the film, and then it can be cut again, which is cumbersome to operate. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] like Figures 1 to 3As shown, a film slitter comprises a lower shell 1 and an upper shell 2 which cooperate with each other, a film roll 3 is placed between the lower shell 1 and the upper shell 2, a slitting knife 8 is fixedly connected to the inner top of the upper shell 2, and an adjustable elastic clamping mechanism 4 is installed through both sides of the outer surface of the lower shell 1, and the adjustable elastic clamping mechanism 4 comprises an adjusting bolt 41 which is threadedly connected to the outer surface of the lower shell 1, one end of the adjusting bolt 41 is fixedly connected to a moving plate 42, and one side of the moving plate 42 is fixedly connected to a first spring 43, and the The other end of the first spring 43 is fixedly connected to a clamping plate 44 in contact with the film roll 3. When in use, the first spring 43 can apply pressure to the clamping plate 44, thereby driving the clamping plate 44 to clamp the film roll 3 to prevent the film roll from rotating when not in use, and the rotation of the adjusting bolt 41 can drive the movable plate 42, the first spring 43 and the clamping plate 44 to move, and can clamp and limit film rolls of different widths, thereby improving practicality. The existing device structure is fixed and cannot limit film rolls of different widths, thereby reducing practicality.

[0025] Embodiment 2:

[0026] like Figures 3 to 6 As shown, an elastic support conveying mechanism 5 is installed between the upper surface of the lower shell 1 and the interior of the upper shell 2. The elastic support conveying mechanism 5 includes a plurality of second springs 51 fixedly connected to the upper surface of the lower shell 1, and a bottom plate 52 is fixedly connected between the top ends of the plurality of second springs 51. A rotating shaft 53 is rotatably connected to the interior of the upper shell 2, and a friction roller 54 matching the bottom plate 52 is fixedly sleeved on the outer surface of the rotating shaft 53. Both ends of the rotating shaft 53 are fixedly connected to knobs 55. When in use, after the slitting knife 8 slits the film, the remaining end of the slitting will be at the rear side of the slitting knife 8. At this time, it is only necessary to rotate the knob 55 to drive the rotating shaft 53 and the friction roller 54 to rotate, so that the slit end can be conveyed out with the cooperation of the bottom plate 52, so as to facilitate the next use, thereby solving the problem that the existing slitter is inconvenient to operate the remaining film after use.

[0027] Embodiment 3:

[0028] like Figure 6 As shown, a limiting mechanism 6 cooperating with the elastic support conveying mechanism 5 is fixedly installed inside the upper shell 2, and the limiting mechanism 6 includes a third spring 61 symmetrically fixedly connected to both sides of the top inside the upper shell 2, and an arc-shaped friction plate 62 is fixedly connected to the bottom end of the third spring 61, and the lower surface of the arc-shaped friction plate 62 contacts the outer surface of the rotating shaft 53. The third spring 61 applies pressure to the arc-shaped friction plate 62, so that the arc-shaped friction plate 62 can squeeze the rotating shaft 53 to prevent the rotating shaft 53 and the friction roller 54 from rotating when not in use, thereby fixing the remaining end of the film slitting.

[0029] Embodiment 4:

[0030] like Figure 1 As shown, a connection mechanism 7 is installed between both sides of the lower shell 1 and the upper shell 2. The connection mechanism 7 includes a first curved plate 71 fixedly connected to one side of the outer surface of the lower shell 1. The outer surface of the upper shell 2 is fixedly connected to a second curved plate 72 matched with the first curved plate 71. The first curved plate 71 and the second curved plate 72 are combined into a complete ring. The outer surfaces of the first curved plate 71 and the second curved plate 72 are threadedly sleeved with a fixing ring 73. The outer surface of the fixing ring 73 is provided with anti-slip grooves. The first curved plate 71 and the second curved plate 72 are both threadedly connected with the fixing ring 73. When disassembling, it is only necessary to rotate the fixing ring 73 to remove the fixing ring 73. At this time, the lower shell 1 and the upper shell 2 can be separated. When installing, it is only necessary to thread the fixing ring 73 on the first curved plate 71 and the second curved plate 72 to achieve the installation of the lower shell 1 and the upper shell 2. The operation is simple and convenient to use.

[0031] Working principle: When in use, the film roll 3 is placed inside the lower shell 1, and then the adjusting bolts 41 on both sides are rotated according to the width of the film roll 3. The rotation of the adjusting bolts 41 can drive the movable plate 42, the first spring 43 and the clamping plate 44 to move, so that film rolls of different widths can be clamped and limited, thereby improving practicality. The existing device structure is fixed, and it cannot limit film rolls of different widths, thereby reducing practicality. Pull out one end of the film roll 3 and place it on the bottom plate 52, then cover the upper shell 2, and fix the first arc plate 71 and the second arc plate 72 through the fixing ring 73, so as to realize the installation of the lower shell 1 and the upper shell 2. When it is necessary to cut the film, at this time, only the film needs to be pulled out, and then it can be cut by the slitting knife 8. After cutting, the first spring 43 can apply pressure to the clamping plate 44, thereby driving the clamping plate 44 to clamp the film roll 3 to prevent the film roll from rotating when not in use, and the third spring 61 applies pressure to the arc friction plate 62, so that the arc friction plate 62 can squeeze the rotating shaft 53 to prevent the rotating shaft 53 and the friction roller 54 from rotating when not in use, so that the remaining end of the film can be fixed. When the next slitting is required, it is only necessary to turn the knob 55. The rotation of the knob 55 drives the rotating shaft 53 and the friction roller 54 to rotate, so that the slit end can be transported out with the cooperation of the bottom plate 52, so that it is convenient for the next use, thereby solving the problem that the existing slitter is inconvenient to operate the remaining film after use.

[0032] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
