Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to an automatic feeding device for a sawing machine, and the utility model relates to the field of sawing machine feeding work. Background Art

[0002] During sawing operation, in order to ensure production efficiency, a certain amount of blanks need to be prepared on the storage table. When one blank is sawed, another one can be added in time.

[0003] Most of the existing sawing machine loading devices are loading trolleys, which lift the materials through pneumatic, hydraulic or mechanical transmission and transport them to the sawing roller. However, the loading trolley has a complex structure and a high failure rate. In addition, the loading trolley is usually an independent device. Writing it into the sawing machine system program in the automation program requires high requirements for the staff, and it is also troublesome to maintain. For large workpieces, when the loading trolley fails, the entire machine tool cannot be used. Therefore, it is necessary to provide a mechanism that can automatically load materials.

[0005] The technical solution of the utility model is:

[0006] An automatic feeding device for a sawing machine comprises a feeding supporting air cylinder, a feeding shift fork, a material storage table and a shift fork swing supporting member;

[0007] The feeding fork is an 'L'-shaped frame, the connecting section of the feeding fork is rotatably connected to the fork swing support, the fork swing support is arranged below the sawing roller, the driving support section of the feeding fork is connected to the telescopic end of the top of the feeding support air cylinder, the material storage table is arranged close to the sawing roller, the working section of the feeding fork is arranged between the material storage table and the sawing roller, and the working end of the feeding fork reciprocates around the fork swing support between the material storage table and the sawing roller.

[0008] Furthermore, the bottom of the feeding support air cylinder body is rotatably connected to the workbench through a connecting seat, and the top telescopic end of the feeding support air cylinder is rotatably connected to the driving support section of the material shifting fork through a pin shaft.

[0009] Furthermore, the working section of the feeding fork is an arc-shaped support, and the top end surface of the working section of the feeding fork moves along an arc-shaped trajectory between the material storage table and the sawing roller.

[0010] Furthermore, the top end surface of the working section of the feeding fork is a 'V' shaped working surface.

[0011] Furthermore, the working surface of the material storage table close to the sawing roller is an inclined surface.

[0012] Furthermore, when the loading fork is located at the lowest end, the top end surface of the working section of the loading fork is flush with the bottom end surface of the material storage platform.

[0013] Furthermore, when the feeding fork is located at the topmost position, the top end surface of the working section of the feeding fork is higher than the top of the sawing roller.

[0014] Compared with the prior art, the utility model has the following effects:

[0015] 1. In the present application, the loading fork 2 is driven by the loading support air cylinder 1 to move between the material storage table 3 and the sawing roller 5. When the loading fork 2 moves to the top, the material 4 falls onto the sawing roller 5.
