The embodiment of the invention provides a cutting device for a degradable polyethylene thermal shrinkage film. As shown in fig. 1 to 3, a cutting device for a heat-shrinkable film of degraded polyethylene, comprising: the base 1, the unreeling roller 21, the compacting section, the cutting section, the first conveying roller 31, the second conveying roller 32, the third conveying roller 33, the fourth conveying roller 34, the wind-up roller 22 and the driving section which are sequentially arranged from left to right, wherein,
the unreeling roller 21 is arranged on the top of the base 1;
the pressing part is used for pressing the heat-shrinkable film;
the cutting part is used for cutting two sides of the heat-shrinkable film;
the first conveying roller 31 is obliquely arranged, the second conveying roller 32 and the third conveying roller 33 are vertically arranged, the fourth conveying roller 34 is obliquely arranged, the edge material 71 after trimming is changed from a horizontal state to a vertical state after passing through the first conveying roller 31 and the second conveying roller 32, the edge material 71 is separated from the good material 72 after passing through the third conveying roller 33, and then the edge material 71 passes through the fourth conveying roller 34 to reach the winding roller 22 and is in a horizontal state;
the driving part is in transmission connection with the wind-up roller 22 and is used for driving the wind-up roller 22 to rotate.
During operation, the heat-shrinkable film is wound on the unreeling roller 21, the heat-shrinkable film passes through the compacting part and then is cut through the cutting part, the good material 72 is directly wound on the reeling roller 22 after cutting, the rim charge 71 is changed into a vertical state from a horizontal state after passing through the first conveying roller 31 and the second conveying roller 32, the second conveying roller 32 and the third conveying roller 33 are arranged in a staggered manner, the rim charge 71 is separated from the good material 72 after passing through the third conveying roller 33, and then the rim charge 71 passes through the fourth conveying roller 34 and reaches the reeling roller 22 and is in a horizontal state, so that the good material 72 and the rim charge 71 wound on the reeling roller 22 can be separated by a distance, and the subsequent treatment of the rim charge 71 is facilitated.
From the above, the device can separate the good material 72 from the rim charge 71, so as to facilitate the subsequent treatment of the rim charge 71.
In some embodiments, the cutting part comprises a portal frame 41, two groups of cutting units are arranged on the portal frame 41, each cutting unit comprises a first air cylinder 42, a sliding block 43 is arranged at the telescopic end of each first air cylinder 42, the sliding blocks 43 are slidably connected to the portal frame 41, a second air cylinder 44 is arranged on each sliding block 43, and a cutting knife 45 is arranged on the telescopic shaft of each second air cylinder 44.
