[0020] 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.

[0021] Please see Figure 1-3This utility model provides a technical solution: an adjustable pressure roller structure for furniture edge banding, including a board conveying roller group 2, on which a board to be processed 9 is disposed. A second motor 3 is installed on one side of the board conveying roller group 2, and the shaft of the second motor 3 is connected to the roller shaft on the board conveying roller group 2 via a coupling. This structure drives the board conveying roller group 2 through the second motor 3, which can realize the automatic conveying of the board to be processed 9. In this application, the board to be processed 9 and the edge banding strip 1 are both edge banding materials, and are only used to clarify the positional relationship between the pressure roller frame 7 and the pressure roller body 8 and the board conveying roller group 2 and the edge banding strip 1. Therefore, they are not used in this application. In detail, both sides of the sheet metal conveying roller assembly 2 are fixedly connected to a fixed frame 4, which has an "L" shape. The fixed frame 4 and the mounting plate 5 are slidably connected. The adjusting electric cylinder 6 is symmetrically distributed about the bisector of the fixed frame 4. This structure can move the mounting plate 5, the pressure roller frame 7, and the pressure roller body 8 by adjusting the electric cylinder 6, thereby adjusting the pressure of the pressure roller body 8. The inner wall of the mounting plate 5 is fixedly connected to a telescopic rod 11, and the outer wall of the pressure roller frame 7 is fixedly connected to a sleeve rod 10. One end of the telescopic rod 11 is inserted into the sleeve rod 10. Multiple telescopic rods 11 and sleeve rods 10 are distributed longitudinally at equal intervals about the inner wall of the mounting plate 5. The sleeve rod 10 is slidably connected. One end of the telescopic rod 11 in this structure is connected to the inside of the sleeve rod 10 via a spring. The telescopic rod 11 and the sleeve rod 10 ensure the stability of the connection between the pressure roller frame 7 and the mounting plate 5, while also allowing the pressure roller frame 7 and the pressure roller body 8 to move and adjust the pressure. The pressure roller body 8 is rotatably connected to the inner side of the pressure roller frame 7. Multiple pressure roller bodies 8 are provided. This structure not only supports the sheet material 9 to be processed and the edge banding strip 1, but also does not affect the movement of the sheet material 9 to be processed and the edge banding strip 1. The edge banding strip 1 is provided on the inner side of the pressure roller body 8 and is attached to one side of the sheet material 9 to be processed. The edge banding strip 1 in this structure is wound on the winding equipment. The automatic conveying system allows the edge banding strip 1 to be glued to one side of the material to be processed 9 after being conveyed. An adjusting electric cylinder 6 is fixedly connected to the outer wall of the fixed frame 4, and an mounting plate 5 is provided on the inner wall of the fixed frame 4. One end of the adjusting electric cylinder 6 is connected to the mounting plate 5. A pressure roller frame 7 is movably connected to the inner side of the mounting plate 5. The pressure roller frame 7 is located on one side of the material to be processed 9, and a pressure sensor 12 is installed on the outer wall of the pressure roller frame 7. The pressure sensor 12 is located between the pressure roller frame 7 and the mounting plate 5. The pressure sensor 12 of this device is electrically connected to the adjusting electric cylinder 6 and controlled by a PLC. The pressure sensor 12 can detect the pressure of the pressure roller body 8 in a timely manner, which facilitates the automatic adjustment of the adjusting electric cylinder 6.

[0022] Working principle: When using this adjustable pressure roller structure for furniture edge banding, the board to be processed 9 is first placed on top of the board conveying roller group 2. At the same time, during the conveying process, the edge banding strip 1 is coated with glue and adheres to one side of the board to be processed 9. During the adhesion process, the adjusting electric cylinder 6 pushes the mounting plate 5, so that the pressure roller frame 7 and pressure roller body 8 on the inner side of the mounting plate 5 move closer to the outer wall of the edge banding strip 1, so that the pressure roller body 8 applies pressure to the pressure roller body 8 and the board to be processed 9. During the pressurization process, the pressure sensor 12 senses the pressure. When the pressure sensor 12 detects that the pressure is too high, the adjusting electric cylinder 6 adjusts and resets synchronously. If the pressure sensor 12 detects that the pressure is too low, the adjusting electric cylinder 6 adjusts and pushes the pressure roller frame 7 and pressure roller body 8 to increase the pressure.

[0023] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
