Problems solved by technology

In addition, in the production process of garbage bags, when the sizes and specifications of the garbage bags are different (that is, when the length and width of the garbage are different), it is necessary for the operator to frequently switch the punching dies on the punching machine to process different sizes and specifications. Garbage bags are processed, and the operation steps are cumbersome

Abstract

The invention relates to the technical field of garbage bag production equipment, in particular to a sealing and punching device for garbage bag production. Traction mechanism, a top plate is fixed above the middle of the U-shaped frame, and two mutually parallel first bar-shaped openings and second bar-shaped openings are spaced apart on the top plate, which are located on the rotating rod directly above the first bar-shaped opening. A fan-shaped cam is arranged, a top cam is arranged on the rotating rod directly above the second bar-shaped opening, a bottom block is arranged on the bottom wall of the U-shaped frame under the top plate, and a bottom block is arranged directly below the first hot pressing strip. A second hot pressing bar is arranged on the surface, and a bar-shaped pressing groove is opened on the upper surface of the bottom block directly below the punching mechanism; the entire device disclosed in the present invention can realize the sealing and punching processing of the garbage bag only by one pulling action , and the whole processing process is carried out continuously, and its processing efficiency is high.

Description

technical field [0001] The invention relates to the technical field of garbage bag production equipment, in particular to a sealing and punching device for garbage bag production. Background technique [0002] Garbage bags are plastic bags used in conjunction with trash cans in daily life, and are mainly used to collect garbage in daily life. At present, the garbage bags sold in the market are generally sold in rolls. After unfolding it, a long plastic bag is formed. The plastic bag has a seal at regular intervals and a row of punching holes parallel to the seal. The sealing part and a row of punching holes are arranged so that the user can directly tear it along the punching hole during use, and then unfold the garbage bag at the tearing place and put it on the trash can. However, in the current production and processing process of garbage bags, the sealing and punching are carried out in two steps, and the production process is not only complicated, but also has low produ...
