Fully automatic bag making machine that can be used as a coated woven bag to fit the bottom of the bag

Abstract

The invention discloses a fully-automatic bag making machine with gluing and bottom-wrapping functions of a film-coated woven bag. The fully-automatic bag making machine is characterized by comprising a cloth feeding device, a printing device, a coating device, a molding device, a buffer device, a cutting device, a steering device, a stitching device and a bottom-wrapping device, wherein the cloth feeding device is used for supplying planar cloth; the printing device is used for printing patterns on the cloth; the coating device is used for coating the outer surface of the cloth with a layer of an anti-skidding material; the molding device enables the planar cloth to be molded into a cylindrical bag body; the bag body is cut by the cutting device and then enters the steering device; before entering the steering device, the bag body passes through the buffer device to adjust the material conveying speed of previous operation and subsequent operation; then the bottom of the bag body is stitched and coated with a sealing tape by using the stitching device and the bottom-wrapping device, so that the effect of completing making of a cylindrical bag through fully-automatic line production can be achieved.

Description

technical field [0001] The invention relates to a bag making machine, in particular to a fully automatic bag making machine which can be made into a cylindrical bag from a flat plastic cloth (paper) and can be used as a film-coated woven bag to fit the bottom of the bag. Background technique [0002] see figure 1 Generally, the cylindrical bag forming machine 10 mainly includes a printing mechanism 11, a group of ring frame mechanisms 12, a sticking mechanism 13, a forming mechanism 14, a cutting mechanism 15 and a conveying mechanism 16. The ring frame mechanism 12 is erected There are a plurality of material wheels 121, which can provide continuous plane PP plastic cloth or paper material 1, so that the plastic cloth (paper) material 1 can print predetermined characters on the surface through the printing mechanism 11, and then transport it to the adhesive. The pasting mechanism 13 applies glue along the edge of the raw material 1, and the forming mechanism 14 is provided...

Problems solved by technology

[0003] Although the forming machine 10 can indeed transform the flat cloth (paper) into a cylindrical shape, the production of the cylindrical bag 4 must be divided into two stages, mainly because the sewing action of the latter process takes a long time , the time schedule cannot be coherent and synchronized with the front-end process. The two-stage operation will prolong the completion time of the entire cylindrical bag 4, and the production efficiency cannot be effectively improved. Moreover, the subsequent sewing work is carried out manually, and the production speed Slow and wasteful of labor costs

[0004] see figure 2 In the past, there was a forming machine 20 that can automatically sew the bottom of a cylindrical bag, which mainly includes a set of feeding ring frame 21, a cutting mechanism 22, a transfer mechanism 23 and a sewing mechanism 24, the feeding ring frame 21 is provided with a reel 211, which can be used to set up a continuous cylindrical cloth 5, and the cylindrical cloth 5 can be transported into the cutting mechanism 22. The cutting mechanism 22 has a cutting knife (not shown) inside, which can The cylindrical cloth 5 is cut into sections of cylindrical cloth 6 according to predetermined specifications, and the cylindrical cloth 6 is clamped by the transfer mechanism 23 and carried to the sewing mechanism 24 along a 90-degree turning path. The sewing mechanism 24 has a The sewing machine 241 can sew the bottom edge of the cylindrical cloth 6, so that a cylindrical bag 7 can be completed. Although the above-mentioned forming machine 20 has the function of automatically sewing the bottom edge, it does not have the ability to turn the flat cloth into a round bag. The function of the cylindrical bag, the feeding ring frame 21 is limited to use the already made cylindrical cloth 5, and in the process of making the cylindrical cloth 5 into a cylindrical bag, it must be implemented on the surface of the formed cylindrical bag. Laminating or coating a layer of non-slip material is very difficult, so the finally manufactured cylindrical bag 7 has poor waterproof and anti-slip properties, and poor practicability
