Description

A packaging bag easy-tear line embossing machine that automatically adjusts the incision position

technical field

The invention relates to the field of packaging bag production equipment, in particular to a packaging bag easy-tear line embossing machine that automatically adjusts the position of the incision.

Background technique

Pillow packaging bags have been widely used in food and pharmaceutical packaging industries due to their quantitative packaging, convenient access, high quality, and low cost. In order to facilitate the opening of the packaging bag, many product packaging designs have easy-tear openings.

At present, the common production methods of easy-tear openings in the market include molding method, offline laser method, knife cutting method and easy-tear packaging materials. Among them, the molding method and the off-line laser method both need the cooperation of the packaging material manufacturer. The knife cutting method is to install a knife on the pillow packaging machine. During the production process, the easy-to-tear openings are cut on the horizontal seal and the vertical seal of the small bag respectively. , their respective disadvantages are:

(1) The molding method is to mold the easy-to-tear line in advance during the production process of the composite film, and the prefabrication cost is very high.

(2) Due to the secondary stretching problem of the paper skin in the off-line laser method, it is easy to deform the paper skin, resulting in the problem that the easy-to-tear line is difficult to tear when it passes through the horizontal seal.

(3) The knife cutting method is to install a knife on the pillow packaging machine so that during the production process, the knife acts on the horizontal seal and the vertical seal of the packaging bag to cut out the easy-to-tear openings, and the maintenance cost is high.

(4) It is difficult to open the packaging pouches of ordinary packaging materials, and the commercially available easy-tear packaging materials are expensive and costly to use because of their special formula.

Some of the packaging bags produced by the factory now need to have an easy-tear line on the mouth of the bag, but the easy-tear line is likely to cause film breakage at the beginning of machine calibration. In order to reduce loss, workers will cause many packaging bags without easy-tear Thread, this part of the bag is usually processed by hand, which requires a lot of manpower and material resources, which is not conducive to the development of the enterprise;

At the same time, due to the different lengths of each type of packaging bag, the calibration operator also needs to replace the easy-to-tear thread cutter wheel according to the length of the packaging bag when calibrating the machine, which is inefficient.

Chinese patent CN207120521U discloses an easy-tearing thread embossing machine, comprising: an easy-tearing thread cutter wheel, a crimping wheel, a support seat, a lifting assembly and a transport tray group, and the easy-tearing thread cutter wheel is set on the support by the lifting assembly Seat, the crimping wheel is arranged below the easy-tearing thread cutter wheel, and the front end of the easy-tearing thread cutter wheel is provided with a transport disc group, and the motor drives the easy-tearing thread cutter wheel to rotate through the transmission gear.

This patent does not solve the problem that the film is easy to break when the machine is adjusted, and it can only be applied to a packaging bag of one length. To change the length of the packaging bag, it is necessary to replace the easy-tearing thread cutter wheel and the crimping wheel, which is costly and extremely low in efficiency.

Working principle of the present invention:

The staff rolls the packaging bag that has been heat-pressed out of the three-side seal into a roll and installs it on the packaging bag discharge rack 1;

Packaging bag discharge rack 1, used to continuously transport the roll-shaped packaging bags towards the embossing workbench;

Packing bag receiving frame 8, is used for the packing bag that finishes embossing on the embossing workbench and is harvested into roll shape;

Scaling mechanism 3 is used to detect the bottom edge of the packaging bag. The packaging bag is often transparent or translucent, especially the fruit packaging bags provided by customers in the supermarket are transparent and colorless, so the first butt shot type The laser of the photoelectric sensor 3a can pass through the packaging bag through the first light-transmitting hole 2a, so that when the packaging bag passes between the first through-beam photoelectric sensors 3a, the first through-beam photoelectric sensor 3a does not send a signal, and the packaging bag The bottom edge seal of the packaging bag is formed by hot pressing of two transparent plastic films. The surface and interior of the bottom edge seal of the packaging bag are uneven, and the diffuse reflectivity is high, so that the laser light of the first through-beam photoelectric sensor 3a is blocked. The first through-beam photoelectric sensor 3a sends a signal to the industrial computer;

According to the distance between the scale mechanism 3 and the pinch wheel 4, the industrial computer calculates the time required for the packaging bag to move from the scale mechanism 3 to the pinch wheel 4, and sends the signal to the pinch wheel 4 after a delay. When the bottom edge sealing of the packaging bag moves between the pressing wheel 4 and the embossing wheel 5, the industrial computer sends a signal to the pressing wheel 4 and makes the pressing wheel 4 work;

The sizing mechanism 3 makes the embossing machine suitable for packaging bags of different lengths, and there is no need to adjust the equipment when the bottom edge sealing distance of the packaging bag is different;

The pressing wheel 4 actively rotates and drives the embossing wheel 5 to rotate through the transmission mechanism 6, so that the pressing wheel 4 and the embossing wheel 5 work together to emboss the packaging bag to form an easy-to-tear line;

The detection mechanism 7 is used to detect the embossed packaging bag, detect whether the embossing is complete and whether there is any omission, and send the result signal to the industrial computer;

According to the signal sent by the detection mechanism 7, the industrial computer sends a signal to the packaging bag discharging rack 1 and the packaging bag receiving rack 8 to make it continue to load and collect materials, or sends a signal to the packaging bag discharging rack 1 and packaging bag receiving The frame 8 makes it reversely transport the packaging bag, so that the unqualified part moves back between the pressing wheel 4 and the embossing wheel 5, and then presses the packaging bag with incomplete embossing or missing embossing again, thus effectively improving the qualified Rate.
