Handle folding device of double line plastic bag folding machine

Abstract

The invention discloses a handle folding device of a two-line plastic bag folding machine. The handle folding machine is arranged on the two-line plastic bag folding machine and is capable of simultaneously folding handle parts of two stacks of plastic bags produced by a two-line bag manufacturing machine. A handle folding push plate linking device is adopted in the handle folding device, two groups of handle folding push plates, namely four handle folding push plates, are driven under the condition of no increase of a drive cylinder and the handle parts of the two stacks of plastic bags produced by the bag manufacturing machine are folded; the two staggered tail-concealed handle folding push plates can play a role of two handle folding push plates when during pushing and folding, the tails of the staggered tail-concealed handle folding push plates are hidden in one side of a working surface of another staggered tail-concealed handle folding push plate when the staggered tail-concealed handle folding push plate retracts, and therefore, the transverse space of the handle folding push plates is greatly saved, and the handle folding device can be matched with an existing two-line bag manufacturing machine under the condition of no change of the width of the existing two-line bag manufacturing machine. The handle folding device has the advantages of being compact in structure, capable of saving the cost, and convenient to operate and maintain.

Description

technical field [0001] The invention relates to a processing device for a portable plastic bag. Background technique [0002] The handle folding device of the double-line plastic bag folding machine is installed on the double-line plastic bag folding machine, and is used to fold the handles of two stacks of plastic bags that are produced by the double-line bag making machine and placed side by side. Before, the folding and binding process of the portable plastic bag (ie, convenience bag) produced by the bag making machine was all done manually. The applicant has applied for the disclosure of "Automatic Folding and Binding Machine for Plastic Bags", Patent No.: 201110081121; Above-mentioned invention makes the folding of polybag realize automation substantially. However, the bag making machines for processing plastic bags are divided into single-line machines and double-line machines. The single-line machines can only produce one stack of plastic bags at a time, while the d...

Problems solved by technology

Due to the large range of horizontal linear motion of the handle folding device, the lateral distance of the plastic bag folding machine is too wide, that is, the left and right center distance between the two sets of handle folding device working surfaces is too wide to be able to swing with the output of the double-line bag making machine. The two stacks of bags correspond to

This not only needs to increase the width of the folding machine, but also the width of the double-line bag making machine, and is limited by the range of movement of the folding push plate of the handle, and generally cannot fold wider plastic bags.

The widened bag making machine and folding machine are not only labor-intensive and increase the manufacturing cost, but also the widened machine is unstable, takes up a lot of factory space, and is inconvenient to manufacture, transport, install, maintain, and operate

The width of the double-line folding machine is directly affected by the width of the handle folding device, and is limited by the width of the handle folding device
