Positioning mechanism of material loading device for bag making machine

Abstract

The invention discloses a positioning mechanism of a material loading device for a bag making machine. The mechanism comprises a machine frame, wherein the material loading device is arranged at the upper end of the machine frame, and comprises a bearing seat and a rotating shaft; and the rotating shaft is rotationally arranged on the bearing seat. The mechanism is characterized in that: one end of the rotating shaft is connected with a rocking arm; the rocking arm consists of a rocking rod and a rocking handle; one end of the rocking rod is connected with one end of the rotating shaft; through holes are correspondingly formed in the rocking rod and the bearing seat; and a positioning pin is inserted into the through holes of the rocking rod and the bearing seat. After plastic films are wound on the material loading device well, the through hole in the rocking rod is aligned with the through hole in the bearing seat, and then the positioning pin is inserted into the through holes, so that the material loading device can be positioned, and cropping operation can be performed subsequently; and the whole process can be extremely conveniently finished only by one person.

Description

technical field [0001] The invention relates to a bag making machine, in particular to a positioning mechanism for a feeding device of the bag making machine. Background technique [0002] Plastic bags are widely used in product packaging in various industries, with different sizes and shapes. These manufacturers who use plastic bags for product packaging are divided into two categories: [0003] One type is that the plastic bags used are all purchased from outsiders. The dimensions used by these manufacturers are relatively small, which belong to small packages, and the quantity is relatively large. The daily usage often exceeds 10,000 pieces, and they are purchased from manufacturers specializing in the production of plastic bags. It is relatively cost-effective. [0004] The other is that the plastic bags used for product packaging are relatively large in size and specification. The product is a large package, and the number of use is relatively small. Although the dail...

Problems solved by technology

[0006] In the above-mentioned bag making machine, before cutting with a knife, the feeding device needs to be positioned, that is, fixed at a stable position, so that it can be beneficial to cutting neatly, but there is no positioning on the feeding device The mechanism usually requires one person to fix the shaft, and another person to cut it, which requires two people, the cost is relatively high, and the work efficiency is also reduced
