Description

Technical Field

[0001] This utility model relates to the field of sheet processing technology, specifically a fixed-length cutting device for GAG sheet processing. Background Technology

[0002] GAG is a three-layer composite sheet produced by co-extruding an intermediate layer of APET and two layers of PETG raw materials in a suitable ratio. It has a transparency of over 90% and excellent texture, making it suitable for products requiring high transparency. When processing GAG sheets, a fixed-length cutting device is generally used. The working principle of the fixed-length cutting device is to accurately measure the length of the sheet through a sensor or measuring device. When the sheet reaches the preset length, the cutting device starts to cut the sheet.

[0003] When cutting sheet materials, they need to be fixed to prevent them from shaking or tilting during the cutting process, which would affect the cutting quality. However, existing fixed-length cutting devices use pneumatic grippers to cut the sheet materials. Pneumatic grippers move quickly and have a large clamping force, making it difficult to control the clamping force when clamping and fixing the sheet materials. This can lead to the problem of damaging the sheet materials during clamping. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fixed-length cutting device for GAG sheet processing, which has the advantages of stable clamping and less risk of damaging the sheet. It solves the problem that existing fixed-length cutting devices all use pneumatic grippers to cut the sheet. However, pneumatic grippers move quickly and have a large clamping force, making it difficult to control the clamping force when clamping and fixing the sheet, which still leads to the problem of damaging the sheet when clamping it.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fixed-length cutting device for processing GAG sheets, comprising a fixed-length cutting device body, wherein a sheet fixing and stretching mechanism is provided on the fixed-length cutting device body;

[0006] The sheet fixing and stretching mechanism includes a first electric telescopic rod fixedly installed on the surface of the fixed-length cutting device body. A C-shaped fixing frame is fixedly installed at one end of the first electric telescopic rod. A vacuum machine is fixedly installed on the top surface of the C-shaped fixing frame. A second electric telescopic rod is fixedly installed inside the C-shaped fixing frame. A first hollow clamping plate is fixedly installed at the bottom of the second electric telescopic rod. A second hollow clamping plate is fixedly installed inside the C-shaped fixing frame. Adsorption holes are opened on opposite sides of the first and second hollow clamping plates. A first connecting hose is fixedly installed on the side surface of the first hollow clamping plate. One end of the connecting hose is fixedly connected to the side surface of the second hollow clamping plate. A second connecting hose that penetrates the C-shaped fixing frame and communicates with the first hollow clamping plate is fixedly installed on the surface of the vacuum machine.

[0007] Furthermore, there are two C-shaped fixing brackets, which are symmetrically distributed on the surface of the fixed-length cutting device body.

[0008] The beneficial effect of adopting the above-mentioned further solution is that the two ends of the sheet can be fixed by two C-shaped fixing brackets.

[0009] Furthermore, there are two first electric telescopic rods, which are symmetrically distributed on the surface of the C-shaped fixing frame.

[0010] The beneficial effect of adopting the above-mentioned further solution is that the stability of the C-shaped fixing frame during movement can be improved by using two first electric telescopic rods.

[0011] Furthermore, the number of the second electric telescopic rods is four, and the four second electric telescopic rods are evenly distributed between the upper surface of the first hollow clamping plate and the inner surface of the C-shaped fixing frame.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it helps to improve the stability of the first hollow clamping plate during lifting and moving.

[0013] Furthermore, rubber pads are fixedly installed on the opposite side surfaces of the first hollow clamping plate and the second hollow clamping plate, and the surface of the rubber pads has circular holes corresponding to the adsorption holes.

[0014] The beneficial effect of adopting the above-mentioned further solution is that setting rubber pads helps to improve the adhesion between the first hollow clamping plate and the second hollow clamping plate and the sheet surface.

[0015] Furthermore, the outer surface of the C-shaped fixing frame slides in contact with the surface of the fixed-length cutting device body.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it facilitates the movement of the C-shaped fixing frame on the surface of the fixed-length cutting device body.

[0017] Furthermore, the C-shaped fixing frame has two mounting slots on its side surface, and a tension sensor is fixedly installed inside the mounting slot. One end of the first electric telescopic rod is fixedly connected to the tension sensor.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by setting a tension sensor between the first electric telescopic rod and the C-shaped fixing frame, the tension applied by the first electric telescopic rod to the surface of the sheet through the C-shaped fixing frame can be monitored in real time, which can prevent overstretching when stretching the sheet.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] This fixed-length cutting device for GAG sheet processing can adsorb and clamp the sheet through a vacuum machine, a first hollow clamping plate, and a second hollow clamping plate. Compared with the existing technology that uses actuating claws to clamp and fix the sheet, this embodiment will not damage the sheet when clamping it. At the same time, the first electric telescopic rod can drive the C-shaped fixing frame to move, which can stretch the sheet and prevent the sheet from curling. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0028] Please see Figures 1 to 5This embodiment discloses a fixed-length cutting device for processing GAG sheets, comprising a fixed-length cutting device body 1. The fixed-length cutting device body 1 is equipped with a sheet fixing and stretching mechanism, which includes a first electric telescopic rod 2 fixedly mounted on the surface of the fixed-length cutting device body 1. A C-shaped fixing frame 3 is fixedly mounted at one end of the first electric telescopic rod 2. The outer surface of the C-shaped fixing frame 3 slides in contact with the surface of the fixed-length cutting device body 1, facilitating movement of the C-shaped fixing frame 3 on the surface of the fixed-length cutting device body 1. A vacuum machine 4 is fixedly mounted on the top surface of the C-shaped fixing frame 3. A second electric telescopic rod 5 is fixedly mounted on the inner side of the C-shaped fixing frame 3. A first hollow clamping plate 6 is fixedly mounted at the bottom of the second electric telescopic rod 5. The inner side of the C-shaped fixing frame 3... A second hollow clamping plate 7 is fixedly installed on the side. Adsorption holes 8 are opened on the opposite side surfaces of the first hollow clamping plate 6 and the second hollow clamping plate 7. Rubber pads 11 are fixedly installed on the opposite side surfaces of the first hollow clamping plate 6 and the second hollow clamping plate 7. The surface of the rubber pads 11 has round holes 12 corresponding to the adsorption holes 8. The rubber pads 11 help to improve the adhesion between the first hollow clamping plate 6 and the second hollow clamping plate 7 and the sheet surface. A first connecting hose 9 is fixedly installed on the side surface of the first hollow clamping plate 6. One end of the connecting hose 9 is fixedly connected to the side surface of the second hollow clamping plate 7. A second connecting hose 10 is fixedly installed on the surface of the vacuum machine 4, penetrating the C-shaped fixing frame 3 and communicating with the first hollow clamping plate 6.

[0029] There are two C-shaped fixing frames 3, which are symmetrically distributed on the surface of the fixed-length cutting device body 1. The two C-shaped fixing frames 3 can fix both ends of the sheet. There are two first electric telescopic rods 2, which are symmetrically distributed on the surface of the C-shaped fixing frames 3. The two first electric telescopic rods 2 can improve the stability of the C-shaped fixing frames 3 when moving. There are four second electric telescopic rods 5, which are evenly distributed between the upper surface of the first hollow clamping plate 6 and the inner surface of the C-shaped fixing frames 3, which helps to improve the stability of the first hollow clamping plate 6 when moving up and down.

[0030] The C-shaped bracket 3 has two mounting slots 13 on its side surface. A tension sensor 14 is fixedly installed inside the mounting slot 13. One end of the first electric telescopic rod 2 is fixedly connected to the tension sensor 14. By setting the tension sensor 14 between the first electric telescopic rod 2 and the C-shaped bracket 3, the tension applied by the first electric telescopic rod 2 to the surface of the sheet through the C-shaped bracket 3 can be monitored in real time, which can prevent overstretching when stretching the sheet.

[0031] It should be noted that the fixed-length cutting device body 1 in this embodiment is a laser cutting device. The fixed-length cutting device body 1 is controlled by its built-in controller. The tension sensor 14 is connected to the built-in controller of the fixed-length cutting device body 1. The fixed-length cutting device body 1 mainly includes:

[0032] Laser source: Laser sheet cutting machines typically use high-power laser sources to generate laser beams. The choice of laser source affects the type and thickness of the material being cut, as well as the cutting speed.

[0033] Laser beam focusing: A laser beam is focused onto a very small point using an optical system (such as a lens), forming a high-energy-density laser spot. The focused laser spot can generate high temperatures on the surface of a material, causing the material to melt or vaporize rapidly.

[0034] The motion system typically includes: X and Y axis motion: The laser head moves in the X and Y directions via servo motors and a guide rail system to achieve precise control of the cutting path. Z-axis control: In some cases, the Z-axis is used to adjust the distance between the laser head and the material surface to maintain optimal focal length.

[0035] The cutting process typically includes the following steps:

[0036] Material placement: Place the sheet to be cut on the cutting platform, ensuring it is flat and stable.

[0037] Path planning: The cutting path is generated by inputting the cutting graphic and parameters through a computer control system. The cutting path can be designed using CAD / CAM software and imported into the cutting machine's control system.

[0038] Laser cutting: The laser head moves along a preset path while emitting a laser beam. The laser beam irradiates the material surface, instantly heating and melting the material to form a cutting kerf.

[0039] The working principle of the above embodiments is as follows:

[0040] In use, the sheet is fed into the inside of the C-shaped fixing frame 3 and placed on the second hollow clamping plate 7. The first hollow clamping plate 6 is moved downward and comes into contact with the sheet by the second electric telescopic rod 5. At this time, the rubber pad 11 is in contact with the sheet. The vacuum machine 4 is started. The vacuum machine 4 extracts the air from the first hollow clamping plate 6 and the second hollow clamping plate 7 through the first connecting hose 9 and the second connecting hose 10. The sheet can be adsorbed and fixed by the adsorption hole 8 and the round hole 12. The C-shaped fixing frame 3 can be moved by the first electric telescopic rod 2 to stretch the sheet.
