Problems solved by technology

[0007] a. The stainless steel ruler or stainless steel sheet scratches the concave-convex strip of the clip chain, affecting the bite force of the concave-convex strip and the sealing performance of the concave-convex strip after closing
[0008] b. Due to the method of forcibly scraping off the concave-convex strips of the zipper chain, the zipper chains of many bags are opened and then transversely heat-sealed to make bags that cannot be sealed. The reason is that the stainless steel ruler or stainless steel sheet forcibly scrapes off the concave-convex strips The strips are unevenly stressed and the left and right sliding displacements are misaligned. In the state of misalignment, they are heat-sealed and fixed by the transverse heat-sealing mold, so the misaligned concave-convex strips cannot be aligned, and thus lose the proper use function of the zipper bag.
[0009] C. The stainless steel ruler or stainless steel sheet is loose or its position is shifted during production, and many bags are missing and the clip chain is not opened, which affects the customer's packaging
[0010] Even if measures to open the zipper are taken, if the zipper is not fully opened but only a short section is opened, or the zipper of individual bags is not opened at all, the customer's automatic filling and packaging machine will miss packing, and the food or medicine will not be filled correctly. Bags and scattered on equipment causing waste
What's more serious is that the zipper of many bags cannot be pressed and sealed after being opened, and misalignment occurs, thus losing the proper function of the zipper bag

Abstract

The invention discloses a device for online automatically opening concave and convex strips of a zipper storage bag, and belongs to the field of packaging bag production. The device for online automatically opening the concave and convex strips of the zipper storage bag is characterized in that a position adjusting assembly is arranged on a movable rack slide rail of a bag making machine; an automatic zipper opening assembly comprises a mounting seat and an zipper opening plate, wherein the zipper opening plate is fixedly arranged on the mounting seat, and one side, close to the bag feeding direction, of the zipper opening plate is provided with a zipper feeding port; and zipper concave and convex strip guide grooves are formed in the two upper and lower sides of the zipper opening plate,wherein one end of each zipper concave and convex strip guide groove extends to the outlet end of the zipper feeding port, and the other end of each zipper concave and convex strip guide groove penetrates through one side wall of the zipper opening plate. According to the device for online automatically opening the concave and convex strips of the zipper storage bag, the situation that the zipperconcave and convex strips are deformed due to the fact that the strips are scratched in a passing process can be prevented, and the zipper strips of the zipper storage bag still keep good bite force and sealing performance after being opened online by the device.

Description

technical field [0001] The invention belongs to the field of packaging bag production, in particular to a device for automatically opening the concave and convex strips of zipper bags on-line for a bag making machine. Background technique [0002] Since the advent of the zipper bag, it has been widely used in the packaging of coffee, tea, candy, snacks, sugar, cosmetics, medicines, etc. because it is easy to open and take, and easy to press and seal. With the increasing automation of packaging equipment used in the food and pharmaceutical industries, many manufacturers that use zipper bags to package food and medicine have adopted automatic filling and packaging machines, which requires the zipper bags provided by packaging bag manufacturers to be filled before they are delivered to customers. Open the zipper of the zipper bag, otherwise the automatic filling packaging machine will not work. If the zipper is manually opened after bag making, it is not only labor-intensive a...
