DETAILED DESCRIPTION

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is now described in detail in conjunction with the accompanying drawings.

[0019] refer to Figure 1-2 As shown, the utility model provides a feeding support table for laser cutting of flexible plates, including a plurality of support table cross beams 1 and a plurality of support table longitudinal beams 2, wherein the support table cross beams 1 and the support table longitudinal beams 2 form a rectangular frame, and a limit plate groove 11 is provided on the support table cross beam 1, and a first limit plate 12 and a second limit plate 13 are installed on the limit plate groove 11, and the first limit plate 12 and the second limit plate 13 are mirror images of each other, and a plurality of support teeth 15 are arranged at intervals on the support table cross beam 1. The flexible plate 3 to be cut contacts with the support teeth 15, and according to the size of the flexible plate 3 to be cut, by adjusting the distance between the first limit plate 12 and the second limit plate 13 on the same support table cross beam 1, flexible plates 3 of different sizes can be limited.

[0020] The first limit plate 12 and the second limit plate 13 on the same support platform beam 1 form a group of limit plates. According to the length of the flexible plate 3, multiple groups of the first support plates 12 and the second support plates 13 can be correspondingly arranged on different support platform beams 1 along the direction of the support platform longitudinal beam 2.

[0021] A rack 16 is connected to the lower end surface of the first limiting plate 12, and at the same time, a rack 16 is connected to the lower end surface of the second limiting plate 13. The rack 16 and the gear 17 are rotatably connected, and a motor with a locking function (not shown in the figure) is connected to the gear. The rotation of the gear 17 can drive the rack 16 to move in the horizontal direction, thereby changing the horizontal distance between each group of limiting plates 12.

[0022] refer to Figure 3 As shown, the first limiting plate 12 and the second limiting plate 13 are L-shaped, the first limiting plate 12 is composed of a first limiting arm 123 and a first limiting seat 124, the first limiting arm 123 is shaped like a trapezoid with a small top and a large bottom, the outer side surface 125 of the first limiting arm is vertically arranged with the first limiting seat 124, the angle between the inner side surface 126 of the first limiting arm and the upper surface of the first limiting seat 124 is 90-110°, preferably 95-105°, the second limiting plate 13 is composed of a second limiting arm 133 and a second limiting seat 134, the second limiting arm 133 is shaped like a trapezoid with a small top and a large bottom, the outer side surface 135 of the second limiting arm is perpendicular to the first limiting seat 124, and the angle between the inner side surface 126 of the first limiting arm and the upper surface of the first limiting seat 124 is 90-110°, preferably 95-105°, The second limiting arm is vertically arranged with respect to the second limiting seat 134, and the angle between the inner side surface 136 of the second limiting arm and the upper surface of the second limiting seat 134 is 90-110°, preferably 95-105°. The above angle can form a larger upper distance and a smaller lower distance between each group of first limiting arms 123 and second limiting arms 132, which is beneficial for accurately controlling the displacement of the flexible sheet 3 while facilitating the mechanical arm of the laser cutting machine to place the flexible sheet 3 on the support table 100. The first limiting seat 124 and the second limiting seat are respectively provided with a plurality of first fixing holes 121 and second fixing holes 131, and the number of the first fixing holes 121 and the second fixing holes 131 is preferably 2. The first fixing hole 121 and the second fixing hole 131 are used to cooperate with the limit plate groove 11 to limit the first limit plate 12 and the second limit plate 13 on the support platform beam 1 with bolts 14, that is, the first limit plate 12 and the second limit plate 13 can be moved in the horizontal direction along the limit plate groove 11, and the first limit plate 12 and the second limit plate 13 are limited to move in the vertical direction relative to the limit plate groove 11. The limit plate groove 11 is rectangular, which is convenient for adjusting the installation position of the first limit plate 12 and the second limit plate 13 to meet the requirements of flexible plates 3 of different widths.

[0023] In some embodiments, each first limiting plate 12 is independent of each other, and each second limiting plate 12 is independent of each other. A rack 15 and a gear 16 can be installed on each first limiting plate 12 and second limiting plate 13, respectively, so that an irregular limiting area can be formed between the first limiting plate 12 and the second limiting plate 13 to accommodate plates of different shapes.

[0024] In some embodiments, a positioning protrusion 122 is provided on the first limit seat 124, and the height of the positioning protrusion 122 matches the width of the limit plate slot 11. A second positioning protrusion 132 is provided on the second limit seat 134, and the height of the second positioning protrusion 132 matches the width of the limit plate slot 11. When the first positioning protrusion 122 and the second positioning protrusion 132 are installed in the limit plate slot 11, even without tightening the bolt 14, they can play a supporting role to prevent the first limit plate 12 and the second limit plate 13 from shaking up and down, and can also facilitate the installation of the bolt 14; and in normal use, the weight of the first limit plate 12 is supported by the first positioning protrusion 122, and the weight of the second limit plate 13 is supported by the second positioning protrusion 132, so as to avoid the weight falling on the bolt 14, causing the thread wear of the bolt 14 when the first limit plate 12 and the second limit plate 13 are moved horizontally, resulting in the problem of difficulty in disassembly in the later stage.

[0025] In some embodiments, the first positioning protrusion 122 and the second positioning protrusion 132 are composed of a plurality of discontinuous small protrusions, which can ensure the limiting stability while reducing the weight of the first positioning protrusion 122 and the second positioning protrusion 132.

[0026] The first limiting seat 124 and the second limiting seat 134 are respectively provided with a plurality of fixing holes (not shown in the figure) in the vertical direction, and the upper end surface of the rack 15 is provided with a plurality of threaded holes (not shown in the figure), and the first limiting plate 12 and the second limiting plate 13 can be respectively connected to the rack 15 through the fixing holes and the threaded holes by bolts. According to the distance requirements between each set of the first limiting plate 12 and the second limiting plate 13, the first limiting plate 12 and the second limiting plate 13 can be installed on different threaded holes.

[0027] When the laser cutting machine cuts the flexible sheet 3, the mechanical arm of the laser cutting machine places the flexible sheet 3 on the support table 100 through the suction cup, and the first limit plate 12 and the second limit plate 13 are installed on the support table crossbeam 1 to prevent the flexible sheet from shaking and causing displacement. The first limit plate 12 and the second limit plate 13 are movable structures, and the motor drives the gear 17 to rotate, and the gear 17 drives the rack 16 to move in the horizontal direction, thereby driving the first limit plate 12 and the second limit plate 13 to move horizontally in the limit plate slot 11, and changing the distance between each group of the first limit plate 12 and the second limit plate 13 can be applied to flexible sheets of different widths. Increase the cutting accuracy of the laser cutting machine.
