Description

Technical Field

[0001] This utility model relates to the field of automotive instrument panel cutting machine technology, and in particular to an automotive instrument panel cutting machine that is easy to flip. Background Technology

[0002] An automotive instrument panel cutting machine is a high-precision cutting device specifically designed for cutting protective or decorative films on the surfaces of automotive dashboards, instrument panels, and other interior components. Therefore, a type of automotive instrument panel cutting machine with a cooling function, disclosed in CN217494407U, guides the cut automotive instrument panel film between the lower and upper guide rollers and transmits it along their rotation direction. When the film enters this space, the upper guide roller, through the action of an elastic unit, causes the slider to slide slightly within the groove according to the film's thickness. This ensures the upper guide roller is fully in contact with the film, thus cooling it during the film's output process. This rapid cooling and shaping of the cut film prevents edge curling.

[0003] However, the device only supports single-sided cooling and cleaning. If the instrument membrane needs to be sprayed, coated or tested on both sides, it must be turned over manually. Manual turning increases human intervention, reduces the degree of automation, and the membrane surface is easily contaminated or creased during the turning process, which affects the yield of finished products.

The connecting spring rod is horizontally positioned and the cylinder body of the connecting spring rod is fixedly connected to the middle of the side of the mounting bracket.

[0011] Preferably, the mounting bracket also includes;

[0012] Adjustment assembly; The adjustment assembly includes a horizontally arranged double gear shaft that is rotatably connected to the top of a pair of fixed frames at the bottom of the mounting frame.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-4 As shown, an easy-to-turn automotive instrument panel cutting machine includes an upper guide roller 9 and a lower guide roller 10 that is used in conjunction with the upper guide roller 9. There are two upper guide rollers 9 and two lower guide rollers 10. The upper guide roller 9 is used to contact the instrument panel film and achieve cooling. The internal structure of the upper guide roller 9 and the principle of how to achieve cooling of the instrument panel film are referred to the known prior art.

[0026] The film cutting machine also includes a frame assembly; the frame assembly includes a mounting frame 1, with a pair of fixed frames 12 fixedly installed at the bottom and top of the mounting frame 1. Between each pair of fixed frames 12, a horizontally arranged upper guide roller 9 and lower guide roller 10 are provided. After the instrument film passes through the upper guide roller 9 and lower guide roller 10 at the bottom of the mounting frame 1, it continues to move and, after being flipped, passes between the upper guide roller 9 and lower guide roller 10 at the top of the mounting frame 1, achieving double-sided cooling. Between each pair of fixed frames 12, an outer frame 4 and an inner frame 5 are provided. The outer frame 4 and inner frame 5 within the same pair of fixed frames 12... The frames 5 are arranged in parallel. An outer belt conveyor 7 is installed inside the outer frame 4, and an inner belt conveyor 6 is installed inside the inner frame 5. Both the outer belt conveyor 7 and the inner belt conveyor 6 can be commercially available belt conveyors. The outer belt conveyor 7 and the inner belt conveyor 6 at the top and bottom of the mounting frame 1 rotate in opposite directions, utilizing the rotating belts to contact and adhere to both sides of the instrument diaphragm, driving the instrument diaphragm to move under friction. One side of the mounting frame 1 is provided with an outer baffle 2 for abutting against the side of the two outer frames 4 away from the fixed frame 12. Several connecting telescopic rods 14 are provided on the side of the inner frame 5 away from the mounting frame 1. The outer baffle 2 and the connecting telescopic rods 14 restrict the instrument panel film as it passes the middle of the mounting frame 1. That is, the outer baffle 2 and the connecting telescopic rods 14 facilitate the smooth transfer of the instrument panel film from the outer belt conveyor 7 and inner belt conveyor 6 at the bottom of the mounting frame 1 to the outer belt conveyor 7 and inner belt conveyor 6 at the top of the mounting frame 1, thus enabling smooth movement of the instrument panel film. Therefore, the frame assembly is used for the flipping of the automotive instrument panel film. The upper guide rollers 9 between each pair of fixed frames 12 are... Located at the top, the upper guide roller 9 at the top of the inner frame of the mounting frame 1 is rotatably connected to the top fixed frame 12 of the mounting frame 1, and the lower guide roller 10 is slidably connected to the top fixed frame 12 of the mounting frame 1. The upper guide roller 9 at the bottom of the mounting frame 1 is slidably connected to the bottom fixed frame 12 of the mounting frame 1, and the lower guide roller 10 is rotatably connected to the bottom fixed frame 12 of the mounting frame 1. Therefore, in actual use, the lower guide roller 10 at the top of the mounting frame 1 rises while the upper guide roller 9 at the bottom of the frame falls, so that the distance between the upper guide roller 9 and the lower guide roller 10 at the top and bottom of the inner frame of the mounting frame 1 can be adjusted according to the thickness of the instrument film.

[0027] After adjusting the spacing between the upper guide roller 9 and the lower guide roller 10 according to the thickness of the instrument film, the relative spacing between the ends of the outer frame 4 and the inner frame 5 on the same side away from the mounting frame 1 also needs to be adjusted. At the same time, the relative spacing between the outer frame 4 and the inner frame 5 at the top and bottom of the mounting frame 1 also needs to be adjusted to ensure that the instrument film of the corresponding thickness can smoothly pass between the outer baffle 2 and the connecting telescopic rod 14 and move smoothly under the clamping and bonding action of the inner belt conveyor 6 and the outer belt conveyor 7. Therefore: Electric push rods 16 are fixedly installed on both sides of the outer frame 4 and the inner frame 5 facing the mounting bracket 1. The cylinder of the electric push rod 16 of the outer frame 4 at the top of the inner frame of the mounting bracket 1 is distributed at the same height as the end of the upper guide roller 9 at the top of the mounting bracket 1 and is fixedly connected to the fixed frame 12. The cylinder of the electric push rod 16 of the inner frame 5 at the top of the inner frame of the mounting bracket 1 is distributed at the same height as the end of the lower guide roller 10 at the top of the mounting bracket 1 and is inserted into the fixed frame 12. The cylinder of the electric push rod 16 of the inner frame 5 at the top of the inner frame of the mounting bracket 1 is fixedly connected to the top of the mounting bracket 1. The lower guide roller 10 is rotatably connected at its end. The electric push rod 16 cylinder body of the outer frame 4 at the bottom of the inner frame of the mounting frame 1 is distributed at the same height as the lower guide roller 10 at the bottom of the mounting frame 1 and is fixedly connected to the fixed frame 12. The electric push rod 16 cylinder body of the inner frame 5 at the bottom of the inner frame of the mounting frame 1 is distributed at the same height as the upper guide roller 9 at the bottom of the mounting frame 1 and is inserted into the fixed frame 12. The electric push rod 16 cylinder body of the inner frame 5 at the bottom of the inner frame of the mounting frame 1 is rotatably connected to the upper guide roller 9 at the bottom of the mounting frame 1. The extension and retraction of the electric push rod 16 is used to achieve... By moving the corresponding outer frame 4 or inner frame 5, the relative distance between the ends of the outer frame 4 and inner frame 5 on the same side away from the mounting frame 1 can be adjusted. In addition, the height of the lower guide roller 10 located below the top of the mounting frame 1 can be adjusted synchronously by raising and lowering the electric push rod 16 located below the top of the mounting frame 1 along the surface of the fixed frame 12; or the height of the upper guide roller 9 located above the bottom of the mounting frame 1 can be adjusted synchronously by raising and lowering the electric push rod 16 located above the bottom of the mounting frame 1 along the surface of the fixed frame 12.

[0028] A connecting spring rod 3 is provided at the center of the vertical edges on both sides of the outer baffle 2. The connecting spring rod 3 is horizontally set and the cylinder of the connecting spring rod 3 is fixedly connected to the middle of the side of the mounting bracket 1. When the relative distance between the outer frame 4 and the inner frame 5 on the same side away from the mounting bracket 1 is adjusted, the outer frame 4 needs to slide along the direction parallel to the inner frame 5 on the same side. When the outer frame 4 moves away from the mounting bracket 1, the outer baffle 2 pulls the connecting spring rod 3 to extend elastically. When the outer frame 4 moves closer to the mounting bracket 1, the outer baffle 2 is pulled to move synchronously under the elastic contraction of the connecting spring rod 3.

[0029] The mounting bracket 1 also includes an adjustment assembly. This assembly includes a horizontally positioned double-gear shaft 11 rotatably connected to the top of a pair of fixed frames 12 at the bottom of the mounting bracket 1. The gear teeth at both ends of the double-gear shaft 11 are helical. Both ends of the double-gear shaft 11 are meshed with a bidirectional lead screw 13. Rotation of the bidirectional lead screw 13 is achieved by driving the double-gear shaft 11 to rotate. The bidirectional lead screw 13 is vertically positioned, with its upper and lower ends respectively rotatably connected to the opposite sides of the two fixed frames 12 on the same side within the mounting bracket 1. Both ends of the bidirectional lead screw 13 are threadedly connected to the cylinders of electric push rods 16, which are inserted and installed at the top and bottom of the mounting bracket 1. Rotation of the bidirectional lead screw 13, combined with… Figure 2 and Figure 3 This allows two adjacent electric push rods 16 on the left or right side of the mounting frame 1 to move closer or further apart, thus adjusting the distance between the upper guide roller 9 and the lower guide roller 10 at the top and bottom of the frame inside the mounting frame 1. Therefore, the adjustment component is used to adjust the distance between the upper guide roller 9 and the lower guide roller 10 in each pair of fixed frames 12.

[0030] A bevel ring 15 that meshes with the end of a double gear shaft 11 is mounted on the surface of the bidirectional lead screw 13. A motor 17 is fixedly mounted on one side of the mounting bracket 1. A bevel gear block 8 that meshes with the adjacent bevel ring 15 is fixedly mounted on the main shaft of the motor 17. By driving the bevel gear block 8 to rotate using the motor 17, the corresponding meshing bevel ring 15 can drive the corresponding bidirectional lead screw 13 to rotate, and at the same time drive the double gear shaft 11 to rotate. Under the transmission action of the double gear shaft 11, the bevel ring 15 on the other side of the bidirectional lead screw 13 can rotate, thus realizing the rotation of the other side of the connected bidirectional lead screw 13. This allows the two bidirectional lead screws 13 to rotate synchronously and at the same speed.

[0031] In addition, the rotation of the upper guide roller 9 or the lower guide roller 10 connected to the cylinder body of the electric push rod 16 in this solution can be achieved by installing another motor 17 on the cylinder body of the electric push rod 16.

[0032] Working principle: During use, the distance between the upper guide roller 9 and the lower guide roller 10 at the top and bottom of the mounting frame 1 is adjusted according to the thickness of the instrument film. At the same time, the relative distance between the ends of the outer frame 4 and the inner frame 5 on the corresponding sides away from the mounting frame 1, and the relative distance between the outer frame 4 and the inner frame 5 at the top and bottom of the mounting frame 1 are also adjusted. After the adjustment is completed, the instrument film passes through the upper guide roller 9 and the lower guide roller 10 at the bottom of the mounting frame 1, and is continuously conveyed by the inner belt conveyor 6 and the outer belt conveyor 7 at the bottom of the mounting frame 1. Then, after being limited by the outer baffle 2 and the connecting telescopic rod 14, it is transferred to the inner belt conveyor 6 and the outer belt conveyor 7 at the top of the mounting frame 1 and conveyed between the upper guide roller 9 and the lower guide roller 10 at the top of the frame. Double-sided cooling is achieved by using the two upper guide rollers 9.

[0033] The wiring diagrams of the inner belt conveyor 6, outer belt conveyor 7, motor 17, and electric push rod 16 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the inner belt conveyor 6, outer belt conveyor 7, motor 17, and electric push rod 16 will not be explained in detail.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
