Then the packaging material enters a cutter 2 driven by a cutter reciprocating driving mechanism 3, and the cutter reciprocating driving mechanism 3 drives the cutter 2 to move at the same speed as the packaging material, so that the cutter 2 can cut off the packaging material in a moving state. The cutter reciprocating driving mechanism 3 also keeps the support of the packaging materials in front of and behind the cutter 2 through the horizontal supporting mechanism 33, and ensures that the packaging materials in front of the cutter 2 after being cut off can pass through the cutter 2 to continue to move forward stably. The cut packaging material combination with the preset length is stored in a storage mechanism behind the cutter 2, the packaging material is conveyed to a packaging station after being stacked to the preset height, and the aluminum material is packaged mechanically or manually.
In order to deal with the defects of wrinkles, untight fit, mutual displacement and the like caused by different thicknesses, hardness and surface smoothness of different packaging material combinations, the tensioning and flattening mechanism is designed in a targeted mode. The tensioning and leveling mechanism comprises a first leveling and stretching mechanism 12, a transverse limiting mechanism 13 and a second leveling and stretching mechanism 14; the first leveling and stretching mechanism 12 comprises a guide roller 121, a fixed pressing roller 122 and a movable pressing roller 123, wherein the movable pressing roller 123 is arranged above the fixed pressing roller 122 and is used for being matched with the fixed pressing roller 122 to apply uniform pressure to the passing packaging material; the transverse limiting mechanism 13 comprises a fixed baffle 131 and a movable baffle 132 which are respectively arranged at two sides of the passing packaging material, and the movable baffle 132 can move relative to the fixed baffle 131; the second flattening and stretching mechanism 14 is used to apply a second uniform pressure to the packaging material.

After passing through the fixed pinch roller 122 and the movable pinch roller 123, the packaging material combination passes through the fixed flap 131 and the movable flap 132, aligning the packaging material combination. Finally, the packaging material assembly passes through a second leveling and stretching mechanism 14, wherein the second leveling and stretching mechanism 14 comprises a longitudinal movable seat 141 and a rectangular strip 142 arranged on the longitudinal movable seat 141, and the rectangular strip 142 can move up and down relative to the longitudinal movable seat 141.

When the device works, the traction roller lifting cylinder 17 drives the driven traction roller 16 to descend to press the passing packaging material in a combined mode, and the driving traction roller 15 is connected with a power mechanism such as a motor and the like to drive the packaging material to convey forwards through self rotation. According to the combination of different packaging materials, the pulling force of the pulling roll lifting cylinder 17 can be adjusted to provide a suitable clamping force for the packaging materials, prevent the packaging materials from slipping, or convey different materials asynchronously.
When the tensioned and flattened packaging material combination 4 enters a cutting station and is sent out for a preset length, the cutter reciprocating driving mechanism 3 drives the cutter 2 to move at the same speed as the packaging material, then the cutter 2 cuts off the packaging material, and the cut packaging material is continuously conveyed forwards and is flatly stacked at a preset position. The cutter 2 is opened again after cutting off the packaging material, the cutter reciprocating driving mechanism 3 drives the cutter 2 to move back and reset, and the subsequent packaging material passes through the cutter 2 and is conveyed continuously until reaching the preset length and then is cut off by the cutter 2 again. In order to reliably mount the cutting knife 2 and drive the cutting knife 2 to move, the translation frame 31 comprises a slide rail 311, a slide block 312 capable of sliding on the slide rail 311, a translation lower beam 313 arranged on the slide block 312, a support 314 arranged on the translation lower beam 313, and a translation upper beam 315 connected with the top of the support 314; the lower translational beam 313 can reciprocate relative to the slide rail 311 under the driving of the reciprocating driving device.

The fixed blade 21 is fixed on the translational upper beam 315, and the firm translational upper beam 315 provides an integral support for the fixed blade 21, so that the fixed blade 21 is prevented from being deformed or even directly damaged due to excessive stress. The movable blade 22 is arranged below the fixed blade 21 and between the front limiting block 321 and the rear limiting block 322, and the movable blade 22 is substantially limited by the front limiting block 321 and the rear limiting block 322.
Since the cutting blade 2 and the packaging material are at the same speed in the cutting process, which means that the cutting blade 2 is stationary relative to the packaging material, the packaging material behind the cutting blade 2 after cutting may be brought between the movable blade 22 and the rear stopper 322, causing cutting defects. Therefore, the scheme provides a special movable blade structure. The movable blade 22 includes a cutting portion 221 and a tail bearing portion 222 located at a side of the cutting portion 221 and extending horizontally forward. When the movable blade 22 moves upward to cut the packing material in cooperation with the fixed blade 21, the cut end of the packing material is supported on the trailing-end supporting portion 222, and the movable blade 22 then moves downward, and the packing material is moved to the upper surface of the rear stopper 322, thereby preventing the defective portion 221 of the packing material from being defective.

Specifically, the support belt guide rollers 332 include four guide rollers, including a first upper guide roller a, a second upper guide roller b, a first lower guide roller c and a second lower guide roller d, where the first upper guide roller a and the second upper guide roller b are respectively disposed in front of and behind the translation frame 31, and the first lower guide roller c and the second lower guide roller d are disposed below the corresponding first upper guide roller a and the corresponding second upper guide roller b; the first upper guide roller a, the second upper guide roller b, the first lower guide roller c and the second lower guide roller d cooperate to tighten the support belt 331 and keep the support belt 331 between the first upper guide roller a and the front stopper 321 and between the second upper guide roller b and the rear stopper 322 horizontal during the movement of the translation frame 31. When the packaging material is fed into the cutting station, the supporting belt 331 positioned between the first upper guide roller a and the front limiting block 321 is in contact with the packaging material, after the packaging material passes through the cutting knife 2, the supporting belt 331 positioned between the second upper guide roller b and the rear limiting block 322 is in contact with the packaging material, and the supporting belt 331 is driven by the translation frame 31 to synchronously move so as to provide complete support for the packaging material.
The adjustment of the relative position of the fixed blade 21 and the movable blade 22 is particularly important during operation of the cutter 2. In order to ensure that the relative position and orientation of the movable blade 22 and the fixed blade 21 are consistent with the expected position and orientation, a movable blade adjusting block 324 is further arranged in the rear limiting block 322 of the embodiment. The movable blade adjusting block 324 is fixed between the movable blade 22 and the front stopper 321 by an adjusting nut 325. Specifically, the adjusting nuts 325 are arranged at a predetermined distance from top to bottom, penetrate through the rear limiting block 322 and are connected with the movable blade adjusting block 324, and the front-back position and the front-back inclination angle of the movable blade adjusting block 324 can be adjusted by adjusting the adjusting nuts 325 with different heights, so that the relative position and orientation of the movable blade 22 and the fixed blade 21 are adjusted, and the cutting is ensured to be crisp and smooth. In addition, the cutter clearance change caused by abrasion can be quickly adjusted after multiple times of cutting.
The wrapping material should be kept tensioned during cutting, and for this purpose, the wrapping material cutting device further comprises a second traction mechanism 18, which is arranged behind the translation carriage 31, and is used for tensioning the wrapping material at the cutting station before cutting and also providing forward power for the cut wrapping material so that the cut wrapping material is completely discharged.
