[0002] At present, the equipment for mechanically conveying materials is basically to convey the materials one by one and in order to the downstream process equipment. When multiple simultaneous operations (such as simultaneous sawing) need to be performed on the slender flat materials, they can only be completed in the same process, that is, because the flat materials are thin, their vertical state cannot be guaranteed during conveying, so they can only be conveyed in a horizontal state and stacked together.

Using the above-mentioned method, simultaneous and synchronous sawing of multiple stacked materials cannot be realized, and thus the consistency and precision of sawing cannot be guaranteed, so a feeding device capable of simultaneous and synchronous sawing needs to be designed.

[0022] In summary, the flat material loading device realizes the concentration and collection of multiple flat materials, simultaneous overturning and synchronous conveying of the collected materials, changes the state of the flat material, provides protection for the simultaneous and synchronous operation of the downstream equipment on multiple flat materials, and effectively ensures the consistency and precision of the processed flat material of the downstream equipment.

[0023] Since the material distance adjusting mechanism comprises a driving shaft rotatably mounted on the rack and driven by a power source, a plurality of driving arms are fixedly mounted on the driving shaft, the driving arms are arranged in one-to-one correspondence with the feeding guide plates, an adjusting plate is slidably mounted on each feeding guide plate, and the baffle is bent and formed on the adjusting plate; the driving arm is provided with an adjusting long hole, and a connecting piece passing through the adjusting long hole is arranged between the adjusting plate and the driving arm, so that in use, the power source drives the driving shaft and the plurality of driving arms to act, the connecting piece and the adjusting long hole are matched, the swing driving arm drives the movement of the adjusting plate and the baffle, and the purpose of adjusting the distance (i.e., adjusting the size of the material blocking and top feeding channel) is achieved, which effectively meets the conveying requirements of materials of different widths and has high universality.

[0024] The limiting plate and the feeding guide plate form a single-material feeding channel, and a material blocking and top feeding channel is arranged between the baffle and the limiting plate, so that the flat material is orderly and singly slid to the baffle in the single-material feeding channel through the cooperation of the limiting plate and the feeding guide plate, and the flat material is individually top fed by the material blocking and top feeding mechanism, and the structure is simple, and the flat material is good in individual feeding.
