Description

Technical Field

[0001] The utility model relates to the field of degradable environmental protection bag forming devices, in particular to a degradable environmental protection bag forming device. Background Technique

[0002] The so-called degradable environmental protection bag generally refers to a bag whose production materials can be naturally degraded, the degradation time is not too long, and it can be reused multiple times. We can call it a degradable environmental protection bag. When making a degradable environmental protection bag, it needs to be folded in half and then the edges are sealed by a hot pressing process.

[0003] Common degradable environmental protection bag forming devices only have the function of hot pressing and sealing edges, which can hot press and seal the edges of degradable environmental protection bags, but lack the function of cutting off the residual edges, and cannot ensure the flatness of the sealed edges of degradable environmental protection bags. It is easy to occur that the degradable environmental protection bags are easy to warp or wrinkle at the side edges after hot pressing, affecting the product quality.

[0004] Therefore, aiming at the problem that the above-mentioned degradable environmental protection bag forming device lacks the function of cutting off the residual edges, a degradable environmental protection bag forming device can be designed. The second electric telescopic rod drives the mounting plate to move downward, and the mounting plate drives the slitting knife to move downward until the slitting knife cuts the already hot-pressed formed environmental protection bag and the non-hot-pressed formed environmental protection bag. By using two slitting knives, the wrinkled part generated due to hot pressing between the already hot-pressed formed environmental protection bag and the non-hot-pressed formed environmental protection bag can be cut off.

By adopting two slitting knives 9, the wrinkled parts between the hot-pressed environmentally-friendly bag and the unhot-pressed environmentally-friendly bag due to hot pressing can be cut off, so as to solve the problem of the common degradable environmentally-friendly bag forming device, which only includes the hot-pressing edge sealing function and can perform hot-pressing edge sealing on the degradable environmentally-friendly bag, but lacks the function of cutting off the residual edge, and cannot guarantee the flatness of the sealed edge of the degradable environmentally-friendly bag. It is easy for the degradable environmentally-friendly bag to warp or wrinkle at the side after hot pressing, affecting the product quality.
