Description

Technical Field

[0001] This utility model relates to the field of material processing technology, and in particular to an insulating film cutting device. Background Technology

[0002] The process of applying insulating film to side panel production involves several key steps, including aluminum coil slitting, deburring, film peeling, fiberglass cloth slitting, insulating film slitting, and insulating film peeling. Among these, insulating film slitting is a core process, and the performance of the slitting equipment directly affects the quality and production efficiency of subsequent side panel products.

[0003] Chinese patent CN219705405U discloses an insulating film slitting device capable of fixing insulating composite films. The device includes a support base, sliders, a handle, an electric slide rail, blades, a first motor, and rollers. The support base has grooves on both sides, with sliders slidably mounted inside the grooves. A handle is fixed to the slider on the left side, and an electric slide rail is installed between the two sliders. Blades are slidably mounted on the electric slide rail. The first motor is mounted on the left side of the support base, and a roller is mounted on the output shaft of the first motor via a coupling. By turning on a blower, outside air is drawn into the device through a vent plate and air duct, creating suction on the surface of the vent plate to hold the insulating film in place, thus fixing the insulating film to the support base and preventing movement of the insulating film from affecting subsequent slitting operations.

[0004] However, this technical solution cannot adjust the position of the insulating film, making it difficult to accurately adapt to insulating films of different thicknesses and widths. This leads to problems such as film displacement and wrinkles during transmission, which seriously affects the cutting accuracy. It also cannot fully and accurately plasticize the edges of the film, resulting in uneven edge quality after cutting, with burrs and deformation. Furthermore, using a blower to fix the insulating film requires a dust-free environment, which greatly limits the application environment and makes it less applicable. Utility Model Content

[0005] To address the issues of plasticity and applicability of the insulating film in the aforementioned solutions, this invention provides an insulating film cutting device. The insulating film is hot-pressed using a hot-pressing fixture. A conveying roller, a first pressure roller, and a second pressure roller group, driven by a driving component, transport and fix the film material. Limiting components are installed to restrict film materials of different specifications. After the cutting component completes the slitting, three pressure plates sequentially press the edges of the film material against the outer edge of the prismatic cutting anvil for plasticity. The film then falls into a collection trough via an inclined plate. This ensures sufficient plasticity while adapting to different specifications of film materials and different environments, greatly improving the versatility of the cutting device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An insulating film cutting device, comprising: A hot press fixture includes a horizontally arranged base and a heating cover plate arranged above the base and cooperating with the base. The base is equipped with a lever cylinder that drives the cover plate to move up and down. The telescopic end of the lever cylinder is connected to the downward-facing side of the cover plate. A cutting table, wherein a horizontal cutting anvil and a collection trough are provided on the cutting table, and the collection trough is located at one end of the discharge port below the cutting anvil; The transmission assembly includes a conveying roller disposed at the end of the base in the conveying direction, and a first pressure roller and a second pressure roller group rolling on the cutting anvil. The first pressure roller has a first adjustable screw connected to its side; the second pressure roller group includes three pressure rollers arranged sequentially on the cutting anvil along the conveying direction of the insulating film; both the first pressure roller and the second pressure roller group are driven by a drive component assembled inside the cutting table; and... The cutting component, which is designed to move up and down and is set on the cutting table, is used to cut insulating film.

[0007] As an improvement, the cutting table is further provided with a first pressure plate, a second pressure plate, and a third pressure plate. The first pressure plate is located close to the outer side of the second pressure roller group, and the outer edge of the first pressure plate is flush with the edge of the cutting anvil. The first pressure plate is driven to move up and down by a first cylinder. The second pressure plate is set to fit against the first pressure plate, and the second pressure plate is driven to move up and down by a second cylinder. The upper edge of the third pressure plate is flush with the edge of the cutting anvil, and the third pressure plate is driven to move left and right by a third cylinder.

[0008] As an improvement, the upper surface of the base is provided with several sliding grooves, and a first limiting member is slidably disposed in the sliding groove. The first limiting member adjusts the center interval by sliding left and right according to the width of the insulating film.

[0009] As an improvement, the first pressure roller includes two parallel pressure rollers, which are integrally formed.

[0010] As an improvement, a second limiting member is provided at one end of the cutting board near the hot press fixture, and a second adjusting screw that can be adjusted left and right is connected below it.

[0011] As an improvement, an inclined plate is designed at one end of the cutting anvil near the discharge port. The inclined plate is fixedly connected to the cutting anvil and its width is smaller than that of the cutting anvil.

[0012] As an improvement, the outer edge of the cutting board is prismatic, and the first pressure plate, the second pressure plate and the third pressure plate sequentially press the edge of the insulating film onto the prismatic edge of the cutting board to shape it.

[0013] The beneficial effects of this utility model are as follows: (1) This utility model forms a hot pressing space by combining the base of the hot pressing fixture with the heating cover plate. The lever cylinder drives the cover plate to move up and down, which can pre-treat the insulating film by heating (such as softening and shaping) and ensure uniform hot pressing by using the stable pressure of the lever cylinder, providing a flat film material base for subsequent cutting and reducing cutting errors caused by film wrinkles. (2) This utility model enhances the pressing stability of the film material by designing the first pressure roller (a double pressure roller integrally formed in parallel) and the second pressure roller group (three pressure rollers arranged in sequence). With the first adjusting screw that can be adjusted up and down of the first pressure roller, it can be adapted to pressing film materials of different thicknesses, ensuring that there is no slippage or deviation during transmission. (3) This utility model adopts a multi-pressure plate collaborative structure when plasticizing the film material to realize the fixing, vertical plasticizing and horizontal plasticizing of the film material, so that the film material becomes a bending structure, which improves the speed of the subsequent insulating film packaging side plate process and greatly improves the working efficiency of the cutting equipment. (4) Through the structural design of the first limiting member and the second limiting member, this utility model can quickly adapt to film materials of different widths, ensuring accurate center positioning during hot pressing and transmission; further calibrating the position of the film material entering the cutting area, and improving the overall positioning accuracy.

[0014] In summary, this equipment ensures the flatness of the membrane material through hot pressing pretreatment, adapts to membrane materials of different thicknesses and ensures stable transmission through multiple pressure rollers and adjustment structures, improves the edge regularity of the membrane material through multiple pressure plates, and allows the limiting components to quickly adapt to membrane materials of different widths, thus comprehensively improving the cutting quality, efficiency and adaptability.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0017] Example like Figure 1-2 As shown, this utility model provides an insulating film cutting device, including: a hot pressing fixture 1, a cutting table 2, a transmission assembly 3, and a cutting component 4. The hot pressing fixture 1 includes a horizontally arranged base 11 and a heating cover plate 12 arranged above the base 11 and cooperating with the base 11. The base 11 and the heating cover plate 12 form a closed hot pressing space. The insulating film is softened and shaped by heating to stabilize the pressure and ensure uniform hot pressing. The base 11 is equipped with a lever cylinder 13 that drives the cover plate 12 to move up and down. The telescopic end of the lever cylinder 13 is connected to the downward-facing side of the cover plate 12. The hot pressing fixture 1 can reduce film wrinkles from the source and provide a flat substrate for subsequent cutting.

[0018] Preferably, the upper surface of the base 11 is provided with a plurality of sliding grooves 14, and a first limiting member 15 is slidably disposed in the sliding groove 14. The first limiting member 15 can flexibly slide left and right to adjust the center interval according to the width of the insulating film, so as to quickly adapt to the hot pressing positioning of different specifications of film materials and improve the versatility of the equipment.

[0019] The cutting table 2 is provided with a horizontal cutting anvil 21 and a collection trough 22. The collection trough 22 is located at the discharge port end below the cutting anvil 21. More specifically, the cutting table 2 is also provided with a first pressure plate 23, a second pressure plate 24 and a third pressure plate 25. The first pressure plate 23 is located close to the outer side of the second pressure roller group 33, and the outer edge of the first pressure plate 23 is flush with the edge of the cutting anvil 21. The first pressure plate 23 is driven to move up and down by a first cylinder 26. The second pressure plate 24 is set to fit against the first pressure plate 23 and is driven to move up and down by a second cylinder 27. The upper edge of the third pressure plate 25 is flush with the edge of the cutting anvil 21, and the third pressure plate 25 is driven to move left and right by a third cylinder 28.

[0020] It is worth noting that the outer edge of the cutting anvil 21 is prismatic. The first pressure plate 23, the second pressure plate 24 and the third pressure plate 25 sequentially press the edge of the insulating film onto the prismatic edge of the cutting anvil 21 for plasticization, thereby fixing the film material and plasticizing it vertically and horizontally. This significantly improves the edge regularity, makes the film material into a bent structure, increases the speed of the subsequent insulating film packaging side panel process, and greatly improves the working efficiency of the cutting equipment.

[0021] Preferably, the cutting board 21 is provided with a second limiting member 29 at one end near the hot pressing fixture 1, and a second adjusting screw 291 that can be adjusted left and right is connected below it. The position of the film material entering the cutting area can be further calibrated by fine adjustment of the second adjusting screw 291, thereby enhancing the positioning accuracy.

[0022] Preferably, the cutting anvil 21 is designed with an inclined plate 211 near the discharge port. The inclined plate 211 is fixedly connected to the cutting anvil 21 and its width is smaller than that of the cutting anvil 21. This structural design can better facilitate the smooth falling of the plasticized insulating film from the inclined plate 211 into the collection groove 22. Compared with the inclined plate 211 which lacks this structure, it can better ensure the stable bending of the edge of the insulating film and its entry into the subsequent process.

[0023] The transmission assembly 3 includes a conveying roller 31 disposed at the end of the conveying direction of the base 11, and a first pressure roller 32 and a second pressure roller group 33 rolled on the cutting anvil 21. The first pressure roller 32 adopts a parallel integral molding double pressure roller design to enhance the pressing stability; the first pressure roller 32 is connected to the side with a first adjusting screw 321 that can be adjusted up and down to flexibly adapt to film materials of different thicknesses; the second pressure roller group 33 includes three pressure rollers arranged sequentially on the cutting anvil 21 along the conveying direction of the insulating film, which further smooths the film material through multi-stage pressing; both the first pressure roller 32 and the second pressure roller group 33 are driven by a drive component assembled inside the cutting table 2, which can match the cutting rhythm and ensure the accuracy of transmission.

[0024] The cutting component 4 is designed to move up and down on the cutting table 2. This design allows the cutting component 4 to be precisely aligned with the cutting position. Combined with the stable support of the cutting anvil 21, it effectively reduces burrs and tearing during cutting, ensures the consistency of the insulation film cutting size, and improves the quality of the finished product.

[0025] Work process (1) First, adjust the first limiting member 15 according to the width of the insulating film to be cut to determine the hot pressing positioning reference of the film material. Then, the lever cylinder 13 drives the heating cover plate 12 to move down to heat, soften and shape the insulating film. (2) After hot pressing is completed, the conveying roller 31 conveys the film material to the cutting table 2. During this period, the height of the first pressure roller 32 is adjusted by the first adjusting screw 321 according to the thickness of the film material. Then, the first pressure roller 32 and the second pressure roller group 33 press and smooth the film material in a multi-stage manner and transmit it stably. At the same time, the second limiting member 29 is finely adjusted by the second adjusting screw 291 to calibrate the position of the film material entering the cutting area.

[0026] (3) After the membrane material is in place, the cutting part 4 moves up and down to cut the insulating film. After being transported to the extrusion area, the first cylinder 26, the second cylinder 27, and the third cylinder 28 drive the first pressure plate 23, the second pressure plate 24, and the third pressure plate 25 to move respectively, and extrude the edge of the membrane material to the prismatic edge of the cutting anvil 21 for fixing and plasticizing, forming a bending structure. (4) Finally, the cut insulating film slides smoothly down the inclined plate 211 to the collection groove 22 below, completing the entire cutting process.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
