Problems solved by technology
[0004] This scheme discloses a heat-sealing knife with a bend, which can also be called a heat-pressing strip, and when the heat-pressing strip is a one-piece plastic bag, a large amount of heat is often generated at the bend, so that the plastic bag is overwhelmed. Overheating and melting will affect the production and processing of plastic bags, and the use of a hot-pressing strip to seal plastic bags will often produce a large sticking force with the plastic bag

The invention relates to the field of plastic bag processing, in particular to anti-stamping plastic bag heat sealing equipment and a method. The equipment comprises a collecting mechanism and a discharging mechanism, and further comprises a side heat pressing mechanism, a middle heat pressing mechanism, a mounting frame, a lower hole cutting mechanism, a reciprocating driving mechanism, a plasticbag translation mechanism, a rotary positioning mechanism, a positioning transmission mechanism, a worktable and a heightening plate. According to the anti-stamping plastic bag heat sealing equipmentand the method, the plastic bag translation mechanism can drive plastic bags to quantitatively move forwards by quantitatively moving upwards and downwards; when the side heat pressing mechanism andthe middle heat pressing mechanism conduct heat pressing, the plastic bag translation mechanism cannot drive the plastic bags to move, and the possibility that heat pressing lines of two times are dislocated is avoided; and through the separated heat pressing structure of the side heat pressing mechanism and the middle heat pressing mechanism, on one hand, a strip-type heat pressing strip is replaced to conduct heat pressing processing on the plastic bags, the situation that large heat is often generated at the bent positions is avoided, and on the other hand, large adhesive force between plastic bag sealing openings and the plastic bags is reduced.
Description
technical field [0001] The invention relates to the field of plastic bag processing, in particular to heat-sealing equipment and methods for stamping-resistant plastic bags. Background technique [0002] Conventional hot-pressing strips use one hot-pressing strip to directly heat-seal the plastic bag, but using one-way hot-pressing strip to seal the plastic bag often produces a large sticking force with the plastic bag, and if it encounters When irregular hot-pressing strips are used for hot-pressing, large heat is often generated at the bends, which causes the plastic bags to be melted by the transitional hot-pressing, thereby affecting the production and processing of plastic bags. [0003] my country's patent application number: CN201110238607.X; discloses a method, product and tool for improving the impact pressure resistance of plastic bags, adopts a special heat-sealing line shape, and the heat-sealing plastic bags are more tightly sealed, changing the original straigh...
