[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Reference Figures 1-3An air-bearing platform for an edge-banding machine includes a worktable 1 with a cavity 2 inside. Several air holes communicating with the cavity 2 are opened at the top. A gas generator 7 is connected to the cavity 2. The air holes are divided into exhaust air holes 3 and ball bearing air holes 4. Ball bearings 41 are installed in the ball bearing air holes 4. The exhaust air holes 3 do not have ball bearings 41 installed, thus directly blowing air onto the board on the worktable 1. The exhaust air holes 3 and ball bearing air holes 4 are arranged alternately along the moving direction of the board 5 and / or along the horizontal and vertical directions of the moving board 5. It is understood that the worktable 1 is a component with planar load-bearing function, such as a board 5 structure or a platform-like structure, but not limited to these. The gas generator 7 is a component for blowing air, such as an air pump or compressor, but not limited to these. Regarding the distribution of the exhaust vents 3 and the ball bearing vents 4, for example, the direction of movement of the plate 5 can be considered as a column, and the horizontal and vertical directions of movement of the plate 5 as rows, with one row of exhaust vents 3 and one row of ball bearing vents 4 alternating; it can also be one row of ball bearing vents 4 and one row of exhaust vents 3 alternating, etc., but is not limited to this. With this configuration, during operation, the gas generator 7 is turned on to ventilate the cavity 2, and the gas will be ejected from the exhaust vents 3. The plate 5 placed on the worktable 1 will be pushed upward by the gas ejected from the exhaust vents 3 to reduce the weight of the plate 5; the ball bearings 41 in the ball bearing vents 4 will be blown up by the gas, and the plate 5 can move by pressing on the ball bearings 41, reducing friction. Furthermore, due to the action of the gas ejected from the exhaust vents 3, the pressure of the plate 5 on the ball bearings 41 will be reduced, further reducing friction and preventing the formation of indentations. Furthermore, due to the alternating arrangement of the exhaust vent 3 and the ball bearing vent 4, the air blowing from the exhaust vent 3 and the ball bearing 41 can act evenly on the plate 5, further ensuring the stability of the plate 5 during movement.

[0024] In some embodiments, reference Figure 3 The top opening of the exhaust vent 3 is expanded outward to form a trumpet shape. Here, the outward expansion of the trumpet shape can increase the exhaust diameter of the exhaust vent 3, and avoid excessive concentration of gas exhaust, which could cause local pressure on the plate 5 and damage it.

[0025] In some embodiments, reference Figure 3 The top opening of the suspended ball air hole 4 is recessed, and the diameter of the ball 41 is larger than the diameter of the opening of the suspended ball air hole 4. In this way, when the gas blows upward on the ball 41, the ball 41 will get stuck in the recessed opening, and part of the ball 41 will extend beyond the opening, so the plate 5 can press on the ball 41.

[0026] In some embodiments, reference Figure 4The cavity 2 is provided with several rows, and each row of air holes along the moving direction of the plate 5 is connected to one cavity 2. Each cavity 2 is provided with a control valve 6 to control whether air enters the cavity 2. Further, the end of the cavity 2 is an air inlet 21, which is connected to the gas generator 7 through a main pipe 71. The control valve 6 is installed between the gas generator 7 and the air inlet 21. It can be understood that the cavity 2 can be integrally formed in the workbench 1, or it can be a pipe installed inside the workbench 1. The control valve 6 can control the air intake switch of each row of air holes. In this way, by controlling the number of rows of exhaust holes closed by the control valve 6, the exhaust range of the air holes on the workbench 1 is controlled to suit plates 5 of different widths.

[0027] In some embodiments, reference Figure 1 The air-floating platform for the edge banding machine also includes a support 8 installed at the bottom of the worktable 1. The support 8 is suitable for supporting components of the worktable 1, and can be, for example, a column structure or a block structure. Furthermore, the air-floating platform for the edge banding machine also includes a base 9, on which at least two parallel and concave grooves 91 are provided. A positioning element 81, which slides into the two grooves 91, is installed at the bottom of the support 8. Here, the positioning element 81 can be a flat-bottomed structure, such as a flat disc structure or a plate structure, etc., where the axial direction of the groove 91 is horizontal and perpendicular to the direction of movement of the board 5. Thus, because the positioning element 81 is embedded in the groove 91, the entire worktable 1 cannot move along the direction of movement of the board 5, but can move along the axial direction of the groove 91 to adjust the position of the worktable 1.

[0028] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
