Description

Technical Field

[0001] This utility model belongs to the field of protective film production technology, specifically relating to a slitting device for protective film production. Background Technology

[0002] Protective film production refers to the process of cutting wide raw material film shafts into the required specifications according to certain widths and lengths. This process is very important in the production of protective films because it directly affects the quality of the final product and production efficiency.

[0003] A review of announcement number CN221160515U reveals a plastic product protective film slitting device. This technology discloses "a machine body, a turntable, a first placement rod, a limiting rod, a fixed plate, a sliding plate, a cutting blade, and a connecting rod. The turntable is rotatably mounted on the machine body, with the first placement rod positioned in the center of the turntable. Multiple limiting rods are slidably mounted on the turntable. A fixed plate is fixedly connected to the machine body, and a sliding plate is slidably mounted on the fixed plate. A cutting blade is rotatably mounted on the sliding plate, and a connecting rod is slidably mounted on the sliding plate. The cutting blade is connected to the other end of the connecting rod. By moving the partition forward to position it between two protective films, and then pushing the partition to the right, the partition squeezes the two protective films to move away from each other, thereby separating the protective films and avoiding interference with the slitting process."

[0004] Although the design can separate the protective film to avoid affecting the cutting, the cutting blade is always exposed during the cutting process, which may injure workers and put them in a safety hazard, thus compromising production safety.

[0005] To address the aforementioned problems, this application proposes a slitting device for producing protective films. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a slitting device for protective film production. The lifting and lowering of the cutting machine causes positional changes between the pull rod and the slide rail. This allows the protective cover to open when the cutting machine descends and begins slitting, ensuring stable slitting. After slitting is complete, the cover can be closed again, protecting the cutting machine from exposure and preventing injury to workers when not in use. This reduces safety hazards and ensures high safety and stability in the slitting process.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a slitting device for producing protective film, comprising a support and a cutting machine, a protective cover installed on one side of the cutting machine, and a groove formed on the surface of the protective cover, the surface of the groove being connected to one end of a pull rod, and the pull rod being installed on the surface of the support.

[0008] As a preferred embodiment of the slitting device for producing protective film according to this utility model, a connector is fixedly installed on the surface of the cutting machine, and the connector is fixedly connected to one end of the telescopic cylinder, while the other end of the telescopic cylinder is fixedly installed on the surface of the bracket.

[0009] As a preferred embodiment of the slitting device for producing protective film according to this utility model, a fixed angle block is also fixedly installed on the surface of the cutting machine, and the fixed angle block is also attached to one side of the baffle.

[0010] As a preferred embodiment of the slitting device for producing protective film according to this utility model, the baffle and the protective cover form an integrated structure, and the protective cover and the two side surfaces of the cutting machine are rotatably connected.

[0011] As a preferred embodiment of the slitting device for producing protective film according to this utility model, the surface of the protective cover is symmetrically provided with the sliding grooves, and the protective cover and the cutting machine are a semi-enclosed structure.

[0012] As a preferred embodiment of the slitting device for producing protective film according to this utility model, the chute is L-shaped and symmetrically opened on the surface of the protective cover, and the end of the pull rod is also provided with a cylindrical geometric body that matches the diameter of the chute.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the lifting operation of the cutting machine can cause positional changes between the pull rod and the slide, thereby opening the protective cover when the cutting machine descends and performs slitting work, enabling the cutting machine to perform slitting stably. After slitting is completed, the cutting machine can be closed again, surrounding the cutting machine when it is not performing slitting work, preventing it from being exposed to the outside and affecting the workers, causing personal injury, reducing the occurrence of safety hazards, and making the slitting work more safe and stable.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1 As shown:

[0024] A slitting device for producing protective film includes a support 1.

[0025] In this implementation plan: The existing patent announcement number CN221160515U discloses a plastic product protective film slitting device. This patent discloses a cutting blade. The cutting machine 4 in this application adopts the same technical means as the prior art. The technical means will not be described in detail here. For details on the improvement of the prior art, please refer to the disclosed technology below. In order to solve the technical problems existing in the prior art, such as the "when the device is performing cutting work, the position of its cutting blade is always exposed, which may injure the workers during the slitting work, putting the workers in a safety hazard and not conducive to the safety of production", in combination with the use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve the above problems, a telescopic cylinder 2 and a connecting part 3 are added on the basis.

[0026] Furthermore:

[0027] like Figure 1 - Figure 4 As shown:

[0028] In summary: a protective cover 7 is installed on one side of the cutting machine 4, and a groove 8 is opened on the surface of the protective cover 7. The surface of the groove 8 is also connected to one end of the pull rod 9, and the pull rod 9 is installed on the surface of the bracket 1.

[0029] In this implementation plan: when the cutting machine 4 is performing slitting work, the sliding groove 8 and the protective cover 7 can be pulled by the pull rod 9 to generate rotation between the cutting machine 4 and the slitting work. After the slitting work is completed, the protective cover 7 can close the cutting machine 4 again to ensure the safety of the workers during slitting.

[0030] Furthermore:

[0031] In an optional embodiment, a connector 3 is fixedly mounted on the surface of the cutting machine 4, and the connector 3 is fixedly connected to one end of the telescopic cylinder 2, while the other end of the telescopic cylinder 2 is fixedly mounted on the surface of the bracket 1.

[0032] In this embodiment, the connector 3 and telescopic cylinder 2 installed above the cutting machine 4 can drive the cutting machine 4 to lift and lower, thereby causing the slide 8 and pull rod 9 to exert force under the movement of the cutting machine 4 and the protective cover 7, and realizing the opening of the protective cover 7.

[0033] Furthermore:

[0034] In an optional embodiment, a corner block 5 is also fixedly mounted on the surface of the cutting machine 4, and the corner block 5 is also attached to one side of the baffle 6.

[0035] In this embodiment, the position of the protective cover 7 can be fixed by the connection between the fixed angle block 5 and the baffle 6. When there is no force between the slide groove 8 and the pull rod 9, the fixed angle block 5 can fix the baffle 6 and the protective cover 7, thus preventing the position of the protective cover 7 from shifting.

[0036] Furthermore:

[0037] In an optional embodiment, the baffle 6 and the protective cover 7 form an integrated structure, and the protective cover 7 is rotatably connected to the two side surfaces of the cutter 4.

[0038] In this embodiment, the baffle 6 and the protective cover 7, which constitute an integrated structure, can limit the position of the baffle 6 and the protective cover 7 by the corner block 5, so as to avoid additional rotation between the cutting machine 4 and the protective cover 7.

[0039] Furthermore:

[0040] In an optional embodiment, the surface of the protective cover 7 is symmetrically provided with grooves 8, and the protective cover 7 and the cutting machine 4 are a semi-enclosed structure.

[0041] In this embodiment: the symmetrically opened slides 8 can provide a stable pulling force for the movement of the protective cover 7, and can provide a stable force for the opening of the protective cover 7. The semi-enclosed structure of the cutting machine 4 and the protective cover 7 can keep the side of the cutting machine 4 facing the worker closed, which can reduce certain safety hazards.

[0042] Furthermore:

[0043] In an optional embodiment, the slide 8 is L-shaped and symmetrically opened on the surface of the protective cover 7. The end of the pull rod 9 is also provided with a cylindrical geometry that matches the diameter of the slide 8.

[0044] In this embodiment, the "L"-shaped slide 8 can drive the protective cover 7 and the cutting machine 4 to rotate through the action between the slide 8 and the pull rod 9 when the cutting machine 4 is lifting, thus providing a stable pulling force to the protective cover 7.

[0045] The working principle and usage process of this utility model are as follows: When not performing slitting work, the cutting machine 4 is located at a high position, and the telescopic cylinder 2 is in a retracted state. The connection point between the pull rod 9 and the slide 8 is located in the vertical groove of the slide 8. The fixed angle block 5 and the baffle 6 remain connected to fix the angle of the protective cover 7 and the cutting machine 4. The protective cover 7 then closes one side of the cutting machine 4. At this time, the telescopic cylinder 2 will extend and drive the connecting piece 3 and the cutting machine 4 to move towards the position of the protective film. At the same time, sliding occurs between the pull rod 9 and the slide 8. When the corner of the slide 8 moves to the position of the pull rod 9... At this time, the pull rod 9 begins to exert stress on the slide 8. As the cutting machine 4 gradually descends, the pull rod 9 will exert a pulling force on the slide 8 and gradually stabilize along the transverse groove of the slide 8. The protective cover 7 will rotate between the pull rod 9 and the slide 8 and the cutting machine 4, and pull the protective cover 7 to open the cutting machine 4. Then the cutting machine 4 will perform the cutting work on the protective film. After the cutting work is completed, the cutting machine 4 will rise and reset. At this time, the protective cover 7 will also close the cutting machine 4 again, so that the side facing the worker is protected by the protective cover 7, avoiding the worker from being in a safety hazard.

[0046] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
