Description

Technical Field

[0001] This utility model belongs to the field of thin film processing technology, and in particular relates to a film cutting device for processing insulating films. Background Technology

[0002] Insulating films are used to electrically isolate various conductive electronic devices or components to prevent failures caused by short circuits, breakdowns, etc., between or within electronic devices or components, thereby ensuring the normal operation of various electronic components. During the film production and processing, the formed insulating film will have uneven edges on both sides. When the insulating film is wound up, the edges at both ends of the insulating film will be uneven, so it is necessary to trim the edges on both sides of the insulating film during the winding process.

[0003] Existing film cutting equipment for insulating film processing has difficulty removing waste material during the winding process. While finished film can be directly removed and transported along with the winding roller after winding, waste material needs to be removed separately for reuse. In existing devices, the waste material is tightly wound onto the winding roller after winding, making it difficult to remove and affecting processing efficiency.

[0004] To address these issues, we propose a film cutting device for insulating film processing. Utility Model Content

[0005] The purpose of this invention is to solve the problem of difficulty in removing waste film from the existing technology, and to propose a film cutting device for insulating film processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A film cutting device for processing insulating film includes a film cutting table and a film winding frame that cooperate with each other. The upper part of the film winding frame is rotatably provided with a film winding roller for winding finished products. The lower two sides of the film winding frame are symmetrically rotatably provided with waste film units for winding waste materials. The lower part of the film winding frame is provided with a first drive component for driving the two waste film units to rotate synchronously.

[0008] The waste film unit includes a mounting box rotatably mounted on the side wall of the film roll frame. Multiple moving slots are arranged in a circumferential array on the opposite side of the two mounting boxes, and a horizontal first crossbar is slidably mounted in the moving slot. A second crossbar is slidably mounted horizontally at the bottom of the moving slot below the first crossbar. A first diagonal bar and a second diagonal bar are hinged parallel to each other between the first crossbar and the second crossbar. A second driving component is provided in the mounting box to drive the multiple second crossbars to move synchronously.

[0009] Preferably, the first drive assembly includes a first motor fixedly installed at the lower part of the film roll frame, and a connecting rod is fixedly connected between the two mounting boxes. The first motor drives the connecting rod to rotate through a transmission assembly.

[0010] Preferably, the second drive assembly includes an electric actuator fixedly installed inside the mounting box, with a push block fixedly connected to the telescopic end of the electric actuator, and the other side of the push block being fixedly connected to the ends of a plurality of second crossbars.

[0011] Preferably, a first slider is fixedly connected to both sides of the first crossbar, and a first sliding groove is provided on the upper part of both sides of the moving groove to cooperate with the first slider. A second slider is fixedly connected to both sides of the second crossbar, and a second sliding groove is provided on the lower part of both sides of the moving groove to cooperate with the second slider, and the first sliding groove is perpendicular to the second sliding groove.

[0012] Preferably, a stop bar located outside the mounting box is fixedly connected to the middle of the first crossbar.

[0013] Preferably, both the first and second inclined rods are located on the side of the stop bar facing the mounting box.

[0014] In summary, the technical effects and advantages of this utility model are as follows: This film cutting equipment for insulating film processing drives multiple second crossbars to move synchronously through a second drive assembly. Combined with the parallel and intersecting first and second inclined bars, the multiple first crossbars move closer or further apart. By changing the distance between adjacent first crossbars, the waste film wound on the multiple first crossbars can be easily removed. Compared with existing devices, this avoids the problem of difficulty in removing the waste film after winding due to cost considerations of not using detachable take-up rollers for waste film winding, thus improving processing efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-3 A film cutting device for processing insulating films includes a cutting table 1 and a film winding frame 2 that cooperate with each other. The cutting table 1 is existing technology and includes a rotating cutting blade, which is quite common in the film cutting field and will not be described in detail. A film winding roller 3 for winding finished products is rotatably mounted on the upper part of the film winding frame 2, and waste film units for winding waste film are symmetrically rotatably mounted on both sides of the lower part of the film winding frame 2. A first drive assembly for driving the two waste film units to rotate synchronously is located at the lower part of the film winding frame 2. The waste film units and the film winding roller 3 are staggered vertically, which ensures that both waste film and finished film have sufficient space for winding, improving the practicality of the device.

[0023] Reference Figure 2-4 The waste film unit includes a mounting box 4 rotatably mounted on the side wall of the film roll 2. Multiple moving slots 5 are arranged in a circumferential array on the opposite side of the two mounting boxes 4. A horizontal first crossbar 6 is slidably mounted in the moving slot 5. A second crossbar 7 is slidably mounted horizontally at the bottom of the moving slot 5 below the first crossbar 6. A first inclined bar 8 and a second inclined bar 9 are hinged in parallel between the first crossbar 6 and the second crossbar 7. The first inclined bar 8 can be set to be located outside the mounting box 4 and the second inclined bar 9 can be located inside the mounting box 4. A second drive assembly is provided inside the mounting box 4 to drive the multiple second crossbars 7 to move synchronously.

[0024] This film cutting equipment for processing insulating films involves first cutting the insulating film on the cutting table 1. After cutting, the finished film in the middle is wound onto the film winding roller 3. The second motor 20 is then turned on, driving the film winding roller 3 to rotate, thus achieving continuous winding of the finished film. Since the winding and unwinding of the finished film is existing technology and quite common, it will not be elaborated upon further.

[0025] The waste film on both sides is wound around the first crossbar 6 in the waste film unit on both sides. The two waste film units are driven to rotate synchronously by the first drive assembly, thereby realizing the continuous winding of the waste film on both sides.

[0026] After winding is completed, the second drive assembly is activated to drive multiple second crossbars 7 to move synchronously. In conjunction with the first inclined bar 8 and the second inclined bar 9 which are set in parallel hinges, the multiple first crossbars 6 move closer to each other. At this time, the tightly wound waste film relaxes and can be directly removed.

[0027] Reference Figure 1-3 The first drive assembly includes a first motor 10 fixedly installed at the lower part of the film roll 2, and a connecting rod 11 fixedly connected between the two mounting boxes 4. The first motor 10 drives the connecting rod 11 to rotate through a transmission assembly 12. The transmission assembly 12 is prior art and may include a transmission belt and pulleys. This first drive assembly, through the first motor 10 cooperating with the transmission belt and pulleys, drives the connecting rod 11 to rotate, thereby driving the mounting boxes 4 on both sides to rotate synchronously.

[0028] Reference Figure 4-5 The second drive assembly includes an electric actuator 13 fixedly installed inside the mounting box 4. A push block 14 is fixedly connected to the telescopic end of the electric actuator 13, and the other side of the push block 14 is simultaneously fixedly connected to the ends of multiple second crossbars 7. This second drive assembly moves the push block 14 via the electric actuator 13, causing all the second crossbars 7 in the same mounting box 4 to move accordingly.

[0029] First sliders 15 are fixedly connected to both sides of the first crossbar 6. First sliding grooves 16, matching the first sliders 15, are opened on the upper part of both sides of the moving groove 5. Second sliders 17 are fixedly connected to both sides of the second crossbar 7. Second sliding grooves 18, matching the second sliders 17, are horizontally opened on the lower part of both sides of the moving groove 5, with the first sliding grooves 16 perpendicular to the second sliding grooves 18. For practicality and cost considerations, the first sliders 15 can be located at the hinge point between the first crossbar 6 and the second inclined bar 9, and the second sliders 17 can be located at the hinge point between the second crossbar 7 and the second inclined bar 9. The first sliders 15 and 17 limit the movement of the first crossbar 6 and the second crossbar 7. The second crossbar 7 moves horizontally, and the first crossbar 6 moves perpendicular to the second crossbar 7, thus enabling multiple first crossbars 6 to move closer to or further away from each other.

[0030] Reference Figure 2 , Figure 4 To prevent the waste film from moving to the connection between the mounting box 4 and the film roll 2 during winding and causing an accident, a stop bar 19 located outside the mounting box 4 is fixedly connected to the middle of the first crossbar 6, which improves the safety and stability of the device.

[0031] The first inclined bar 8 and the second inclined bar 9 are both located on the side of the stop bar 19 facing the mounting box 4, so as to prevent the waste film from moving to the hinge point between the first cross bar 6 and the first inclined bar 8 and the second inclined bar 9 and causing an accident, thereby further improving the safety and stability of the device.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
