[0025] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1 , Figure 2 As shown, the utility model discloses an embodiment of a feeding device of a bevel sawing machine, comprising a frame 1, a first transmission roller 2 and a material pressing and feeding mechanism 3, wherein the material pressing and feeding mechanism 3 comprises a table plate 31, a positive pressure mechanism 32 and a linear drive mechanism 33, wherein the positive pressure mechanism 32 is connected to the table plate 31, and is used to press the material against the top surface of the table plate 31, and the linear drive mechanism 33 is connected to the table plate 31, and is used to drive the table plate 31 to move linearly; the first transmission roller 2 is connected to the frame 1 through a first lifting mechanism (not shown in the figure), and the first lifting mechanism is used to drive the first transmission roller 2 to rise and fall; the transmission direction of the first transmission roller 2 is parallel to the driving direction of the linear drive mechanism 33, and when the first transmission roller 2 is lifted, it drives the material on the table plate 31 to move.

[0027] Among them, the pressing and feeding mechanism 3 is located at the feeding port of the angle sawing machine. In this embodiment, by setting the pressing and feeding mechanism 3, the positive pressure mechanism 32 presses each material against the top surface of the table 31, and the linear drive mechanism 33 drives the table 31 to move linearly, so that the material is pressed and transported forward to avoid the misalignment and extrusion of each material during the transportation process. After the table 31 is transported to the right place, the first lifting mechanism drives the first transmission roller 2 to rise, and the material will continue to be driven by the first transmission roller 2 to be fed into the angle sawing machine. Before entering the angle sawing machine, the material is pressed and transported by the pressing and feeding mechanism 3 to realize the positioning and transportation of multiple profiles, which can reduce the sawing waste caused by the misalignment of each profile. At the same time, the profile that is pressed and transported enters the angle sawing machine for processing, which can improve the accuracy of product sawing and forming.

[0028] Specifically, the table 31 is driven by the linear drive mechanism 33 to move from the starting position to the end position along the material transmission direction. At least one of the first transmission rollers 2 is arranged between the starting position and the end position. When the linear drive mechanism 33 drives the table 31 to move to the end position, the table 31 no longer continues to move forward, and the first lifting mechanism drives the first transmission roller 2 to rise above the table 31. The first transmission roller 2 is able to relay the material on the table 31 to realize feeding to the angle sawing machine.

[0029] The linear drive mechanism 33 of this embodiment is a screw drive mechanism, the table 31 is connected to the screw nut of the screw drive mechanism, and moves along the screw axial direction with the screw nut. The frame 1 is provided with a guide rail 11 that slides with the table 31, and the guide rail 11 extends toward the screw axial direction.

[0030] The feeding device of this embodiment also includes a second transmission roller 4, and a second lifting mechanism (not shown in the figure) connecting the second transmission roller 4 and the frame 1. The second transmission roller 4 is arranged at the starting position, or at the feeding end of the starting position.

[0031] When the platen 31 moves from the starting position to the ending position, the second transmission roller 4 can support the material.

[0032] When the table 31 moves to the terminal position, the first lifting mechanism lifts the first transmission roller 2 to a first height, and the second lifting mechanism lifts the second transmission roller 4 to a second height. The first height and the second height are both above the top surface of the table 31. The first transmission roller 2 and the second transmission roller 4 relay the material on the table 31 to feed the angle saw. The first height and the second height are preferably set at the same height.

[0033] In this embodiment, the first lifting mechanism and the second lifting mechanism are both driven by cylinders, but the invention is not limited thereto.

[0034] The positive pressure mechanism 32 of the present embodiment preferably includes a first positive pressure mechanism 32a and a second positive pressure mechanism 32b, and the first positive pressure mechanism 32a and the second positive pressure mechanism 32b are sequentially arranged along the material transmission direction.

[0035] The frame 1 of this embodiment is provided with a drop hopper 12 at the bottom of the table 31, and a head cutting mechanism (not shown in the figure) is provided above the hopper. The second positive pressure mechanism 32b is flush with the end face of the discharge end of the table 31. The head cutting mechanism can cut off the head of the material extending out of the second positive pressure mechanism 32b, so that the sawing machine can directly saw and chamfer the material with the cut head. The materials cut in the sawing machine are all sawed and formed products, which is convenient for pushing and discharging. The head cutting mechanism of this embodiment is connected to the third lifting mechanism (not shown in the figure), and the third lifting mechanism is used to drive the head cutting mechanism to move to stagger with the pressing and feeding mechanism 3 to avoid the head cutting mechanism from interfering with the pressing and feeding mechanism 3.

[0036] The first positive pressure mechanism 32a of this embodiment includes a first mounting plate 321, a first bottom plate 322, a floating joint (not shown in the figure) and a first telescopic driving mechanism 323. The first telescopic driving mechanism 323 is fixed to the first mounting plate 321, and the driving end of the first telescopic driving mechanism 323 is connected to the first bottom plate 322 via the floating joint (not shown in the figure) to reduce the instantaneous pressure on the surface of the material.

[0037] The second positive pressure mechanism 32b of this embodiment includes a second mounting plate 324, a second bottom plate 325, and a second telescopic drive mechanism 326. The second bottom plate 325 is arranged parallel to the first bottom plate 322. The second telescopic drive mechanism 326 is fixed to the second mounting plate 324, and the driving end of the second telescopic drive mechanism 326 is connected to the second mounting plate 324. The second bottom plate 325 is flush with the end surface of the discharge end of the table 31, and the material head cutting mechanism cuts along the end surface of the discharge end of the table 31, and the cut material head directly falls into the drop hopper 12.

[0038] Among them, the first bottom plate 322 includes a plurality of bottom plate units, each of which is connected to the first telescopic driving mechanism 323 through the floating joint (not shown in the figure), and the bottom plate units are arranged in an array along the pressing direction of the side pressure mechanism 35. The pressure of each bottom plate unit on the material is adjustable, and the bottom plate unit can press the material being cut when the material head cutting mechanism moves the cutting head.

[0039] In order to prevent the material from shifting during the moving of the cutting head by the material head cutting mechanism, thereby affecting the accuracy of the sawing and forming of the product, the material pressing and feeding mechanism 3 of this embodiment is further provided with a backing plate 34 and a side pressing mechanism 35. The side pressing mechanism 35 includes a side pressing driving cylinder and a side pressing plate arranged opposite to the backing plate 34. The side pressing mechanism 35 is arranged between the first positive pressure mechanism 32a and the second positive pressure mechanism 32b, and is used to press the side wall of the material against the backing plate 34.

[0040] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
