Heat-seal packaging equipment and cross-seal cutting device thereof

Abstract

A cross-seal cutting device comprises a plurality of hot-pressing seals arranged on a cross-seal shaft, each hot-pressing seal is provided with a cutter groove, a slider, a lead screw nut, a rolling body, a cutter and an auxiliary part are arranged in correspondence to each hot-pressing seal, the cutter is arranged in the cutter groove, the rolling body is provided with a first end and a second end, the first end is abutted to a mounting portion of the cutter, the second end is abutted with the slider, the lead screw nut is arranged in the slider, the slider moves horizontally by adjusting the lead screw nut so that the rolling body can move vertically by being abutted with the slider and the fixing position of the cutter can be changed. The auxiliary part is arranged on the slider and is surrounded between the first end and the second end of the rolling body. The invention further provides heat-seal packaging equipment provided with the cross-seal cutting device. On the heat-seal packaging equipment, the auxiliary part is arranged on the rolling body, stress surface of the rolling body during rolling can be enlarged, local friction to relevant parts by the rolling body is reduced, and accordingly, local damages of the relevant parts can be avoided and the service life is prolonged.

Description

technical field [0001] The invention relates to a packaging device, in particular to a heat-sealing packaging device which utilizes a heat-melt principle to seal a packaging material and a horizontal sealing and cutting device on the device. Background technique [0002] The packaging of many daily necessities or consumer goods, such as the packaging of wet wipes, is automatically processed by packaging equipment. The form of heat sealing is a common method in the packaging industry at present, that is, heating the packaging material (such as a film) to make specific parts of the packaging material in a molten state to bond them together to complete the sealing of the package. [0003] Generally speaking, after the packaging material enters the packaging equipment, the longitudinal sealing (vertical sealing) is realized first through the vertical sealing part, and then the horizontal sealing (horizontal sealing) is realized through the horizontal sealing and cutting part, an...

AI Technical Summary

Problems solved by technology

This adjustment method makes the components (such as cutters, rolling elements, etc.) easy to wear, resulting in the failure to achieve the adjustment effect, and the high rate of packaging damage, which in turn affects the output

At the same time, after the cutter is worn out, the entire horizontal sealing heat head needs to be replaced, resulting in high equipment replacement costs and other problems
