Abstract

The utility model relates to a plastic membrane cutting mechanism for a plastic bag maker. As to traditional plastic bag makers, as most plastic membrane cutting modes adopt a straight cutter mode, the plastic membrane cannot be completely cut off. The plastic membrane cutting mechanism comprises an up-and-down moving beam, a press plate, a blade and bearings; a pair of guide waist slots are formed in the up-and-down moving beam, the bearings are arranged at and can move along the guide waist slots, the bearing and the blade arranged in the up-and-down moving beam are fixed by a pin shaft, the bearing drives the blade to move, and the lower part of the up-and-down moving beam is connected with the press plate by a pair of springs. The plastic membrane cutting mechanism for the plastic bag maker is simple in structure, convenient to operate, high in durability and labor-saving.

Description

Be used in the mechanism that plastic bag making machine cuts off plastic sheeting

Technical field

The utility model belongs to the food packing machine technical field, especially a kind of mechanism that is used in plastic bag making machine cut-out plastic sheeting.

Background technology

Plastic bag making machine in the past, the mode that many plastic sheetings cut off all adopts the straight knife form, can cause the plastic sheeting can not be by complete cut-out like this, causes the follow-up operation can not complete carrying out.

Summary of the invention

The utility model provides a kind of mechanism that plastic bag making machine cuts off plastic sheeting that is used at the deficiencies in the prior art.

The utility model comprises up-and-down movement beam, pressing plate, blade, bearing; Have a pair of guiding gain at the up-and-down movement beam, bearing is arranged on the guiding gain, can move along the guiding gain, and bearing is fixed by bearing pin and the blade that is arranged in the up-and-down movement beam, bearing drives blade movement, and the bottom of up-and-down movement beam is connected with pressing plate by a pair of spring.

Pressing spring also is housed down on the described blade.

The beneficial effects of the utility model: the utility model is simple in structure, handled easily, and the durability height, laborsaving.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model partial cross section figure;

Fig. 3 is blade and bearing connection diagram in the utility model.

The specific embodiment

Further specify the utility model below in conjunction with accompanying drawing.

As depicted in figs. 1 and 2, the utility model comprises up-and-down movement beam 1, pressing plate 6, blade 3, bearing 9, have a pair of guiding gain at the up-and-down movement beam, bearing is arranged on the guiding gain, can move along the guiding gain, bearing is fixed by bearing pin and the blade that is arranged in the up-and-down movement beam, and bearing drives blade movement, and the bottom of up-and-down movement beam is connected with pressing plate 6 by a pair of spring 4,5.Be plastic sheeting 7 to be sheared between pressing plate 6 and the base plate 8.A following pressing spring 2 also is equipped with in blade 3 upper ends.

The utility model mode of operation: up-and-down movement beam 1, move downward and make pressing plate 6 touch plastic sheeting 7 earlier to touch negative 8 again, push down plastic sheeting 7 by

spring

4,5, at this moment up-and-down movement beam 1 continues to pressing down, blade 3 moves along the gain at inclination a angle under the guiding of bearing 9 behind the plastic sheeting 7 when blade 3 touches, easily cut off film

Touch plastic sheeting 7 at blade 3, because the up-and-down movement beam continues to pressing down, the compressed power that acts on the film of following pressing spring 2 beginnings strengthens, blade 3 is guided by bearing 9 simultaneously, to a lateral movement, blade 3 is guided along the gain at inclination a angle by bearing 9, along the gain at inclination a angle to a lateral movement, resistance between blade 3 and the plastic sheeting 7 is reduced, thereby easily cut off plastic sheeting 7.

Claims

1. be used in the mechanism that plastic bag making machine cuts off plastic sheeting, comprise up-and-down movement beam, pressing plate, blade, bearing, it is characterized in that: have a pair of guiding gain at the up-and-down movement beam, bearing is arranged on the guiding gain, can move along the guiding gain, bearing is fixed by bearing pin and the blade that is arranged in the up-and-down movement beam, and bearing drives blade movement, and the bottom of up-and-down movement beam is connected with pressing plate by a pair of spring.

2. the mechanism that is used in plastic bag making machine cut-out plastic sheeting according to claim 1 is characterized in that: pressing spring also is housed down on the described blade.
