Problems solved by technology

But at present, for all such products, in order to ensure no leakage, heat-sealed strips must be attached to all the sutures inside the bag body one by one; The efficiency is low, the effect is not good, and it is easy to have leakage points and missed inspections
Therefore, not only is the production efficiency low, labor-intensive, time-consuming, and material-consuming (part of the sealing layer has to be discarded with the fabric layer as cutting scraps), but also the product produced by manual operation has poor consistency and unstable quality.

Embodiment 1

[0134] Figure 1 to Figure 3 shows a leak-proof bag with an opening 7 according to the present invention.

[0135] figure 1 Shown is the schematic diagram of this embodiment in general use state picture . It includes a fabric layer 1 and a sealing layer 2, both of which together constitute the bag body; the fabric layer 1 bears the gravity of the contents in the bag, and the sealing layer 2 ensures that the contents in the bag in liquid state or containing liquid will not leak.

[0136] figure 2 Shown is the process of the user reaching into the bag body to turn the sealing layer 2 from the inside. image 3 Shown: all fabric layers 1 are turned inside the bag body, and all sealing layers 2 are turned outside the bag body. That is, it turns out that figure 1 The "fabric layer 1 on the outside, seal layer 2 on the inside" shown becomes as follows image 3 "Sealing layer 2 on the outside, fabric layer 1 on the inside" is shown.

[0137] For the convenience of understan...

Embodiment 2

[0140] Figure 4 to Figure 6 shows a leak-proof bag with a handle 6 and an opening 7 according to the present invention.

[0141] Its structure is the same as that disclosed in Embodiment 1, the only difference being that a handle 6 is added in this embodiment.

[0142] The handle 6 can be attached before or after the sealing layer 2 is pasted by methods including pre-sewing or final seaming, ultrasonic, glue bonding, hot stamping, high-frequency welding and the like. In order to reduce the possibility of the sewing machine needle piercing through the leak-proof bag, if sewing is used, it is preferably attached before the sealing layer 2 is attached.

Embodiment 3

[0144] Figure 7 to Figure Shown in 9 is a waterproof bag used in outdoor activities of the present invention (that is, a special form of leak-proof bag, except that the bag mainly does not prevent the content inside the bag from leaking out, but mainly prevents the outside world from leaking out. Rain or water seeps into the inside of the bag body to wet the contents when people carry out outdoor activities).

[0145] After the user puts the content in the bag, the user seals the opening 7 by gathering and tightening the folding strips 8 on both sides of the opening 7, and then bends the tightly rolled folding strips 8 to make the The male buckle 9 is inserted into the female buckle 10, so that the sealing structure will not be scattered.

Abstract

The invention discloses an anti-leakage bag and a preparation method and preparation equipment thereof. Mechanical and automatic batched flow line production of the anti-leakage bags is achieved by apreparation mode of inside and outside overturning. The prepared anti-leakage bag has the advantages of good anti-leakage property, high consistency of products, stable and reliable quality, high production efficiency, low cost and the like, and has a good application prospect and a wide application range.

Description

technical field [0001] The invention relates to a leak-proof bag and the technical field of batch production thereof, and more specifically relates to a waterproof bag and its preparation method and preparation equipment. Background technique [0002] Known leak-proof bags can be mainly divided into film plastic bags, plastic bags obtained by high-frequency welding with PVC material or sandwich cloth, film-coated woven bags, and fabrics coated with a waterproof layer and stitched on the inside of the bag. Laminate fabric bag covered with heat-sealed strips. Among them, the film plastic bag has poor load-bearing capacity and is easy to break; the film-coated woven bag has a bad feel and appearance; The internal gravity generated after the bag is filled with materials is mainly borne by the fabric instead of the sealing layer, so the sealing layer can be made thinner, which can not only reduce the material cost, but also reduce the overall weight and storage volume, and the o...
