Method for making rosin collecting bags

Abstract

The invention discloses a method for making rosin collecting bags. The method comprises the following steps: selecting a plastic film which is consistent with a size requirement for serving as a raw material; performing material consumption calculation and arranging a multi-bag arraying mode according to the sizes of the rosin collecting bags; continuously machining to a multi-bag arraying mode in a heat sealing way through a heat sealing machine. The method comprises the following specific steps: (1) feeding; (2) pressing corners; (3) pressing edges; (4) transversely punching holes; (5) longitudinally slitting or punching holes; (6) coiling. The rosin collecting bags are continuously machined by adopting the heat sealing machine, so that extending lines are bonded uniformly, small holes are avoided, a good sealing effect is achieved, the bags are prevented from leaking oil, and hooks are firm; the method is easy for machining and making, the quantity of procedures is small, and the production efficiency is increased greatly; the utilization ratio of raw materials is very high, and the raw materials can be basically utilized by 100 percent; the comprehensive cost is greatly reduced. Three openings are formed in the made rosin collecting bags, and the bag mouths between the two heat sealing ends of upper bag mouths are small; during use, wood residues and pine needles entering the bags are few.

Description

technical field [0001] The invention relates to a pine resin harvesting material, in particular to a rosin collecting bag for hanging on a pine tree to collect rosin, especially a method for making the rosin collecting bag. Background technique [0002] Pine resin has always been an important raw material in many industries, and harvesting pine resin requires a large number of collection tools, and now the most common application is to use plastic film bags. Hang the plastic film bag on the pine tree, the pine bark above is cut into a "Y" shape, the pine resin slowly seeps out, flows down the "Y" foot, and enters the plastic film bag. Since there is no standard turpentine collection bag, migrant workers in resin mining can only buy agricultural mulch film to make bags by themselves. There are two kinds of home-made loans: one is a square bag, the mulch film is cut to a suitable size, and it is relatively hot and twisted on a small fire candle. This kind of homemade bag is ...

AI Technical Summary

Problems solved by technology

The manufacturing process of such a triangular turpentine bag is complicated, and it does not solve the problem that the bag mouth is too large. When the first batch of oil is collected, the whole bag cannot be removed, and it can only be fished with bare hands, which is dirty and time-consuming.
