Description

TECHNICAL FIELD

[0001] The utility model relates to a plastic woven bag, in particular to an anti-extrusion plastic woven bag. BACKGROUND

[0002] The plastic woven bag is a woven bag made of PP, PE and other plastic raw materials, has the advantages of light weight, good corrosion resistance, low cost, recyclability and the like, and is widely used in agricultural product packaging, chemical product packaging and the like.

[0003] The plastic woven bag is formed into a net structure through weaving of PP, PE and other raw materials, and a plastic film is coated thereon to enhance the sealing property and strength. This structure makes the plastic woven bag have certain tensile strength, but the anti-extrusion capacity is weak. During transportation and stacking storage, the plastic woven bag may bear pressure from above or other directions. If the anti-extrusion performance of the plastic woven bag itself is insufficient, the bag may be deformed or even broken, thereby affecting the preservation and transportation safety of the contents. Some contents (for example, chemical fertilizer) may also cause environmental pollution due to leakage of the woven bag.

[0004] In view of the above problems, the utility model provides an anti-extrusion plastic woven bag. CONTENT OF THE UTILITY MODEL

[0022] The following will combine the drawings in the embodiment of the utility model, Figs. 1-2 The technical scheme in the embodiment of the utility model is clearly and completely described, obviously, the described embodiment is only a part of the embodiment of the utility model, not all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the utility model.

[0023] EMBODIMENT:

[0024] For example, Figs. 1-2As shown, an anti-extrusion plastic woven bag comprises a bag body 11, an inner cavity 12 is formed in the bag body 11, and a plastic film is fixed on the side wall surface of the inner cavity 12 to improve the overall structural strength of the anti-extrusion plastic woven bag. The plastic film cooperates with the woven layer of the bag body 11 to jointly bear the force when subjected to external force, thereby reducing the possibility of damage to the bag body 11 and improving the carrying capacity and service life of the bag body 11.

[0025] A plurality of sponge strips 18 are fixed on the side wall of the inner cavity 12, the sponge strips 18 have a certain deformation ability and can play a shock-absorbing and buffering role during transportation and stacking storage, thereby increasing the anti-extrusion capacity of the bag body 11 to prevent the bag body 11 from being damaged and protect the materials in the inner cavity 12.

[0026] A gas cushion pad 14 is fixed on the bottom of the bag body 11, a plurality of anti-extrusion air bags 13 are fixed on the side wall of the bag body 11 and communicate with the gas cushion pad 14, a gas nozzle 16 is fixed on the gas cushion pad 14, and a protective cap 17 is threadedly connected to the outer curved surface of the gas nozzle 16.

[0027] Before filling materials into the inner cavity 12, the gas cushion pad 14 and the anti-extrusion air bags 13 are in a deflated state, the protective cap 17 is unscrewed and removed, the gas nozzle 16 is connected to a gas filling device (not shown in the figure), and the gas cushion pad 14 and the anti-extrusion air bags 13 are inflated by the gas filling device. When the bag body 11 is subjected to extrusion in the front, back, left and right directions, the anti-extrusion air bags 13 and the gas cushion pad 14 have a certain pressure resistance after inflation, thereby avoiding deformation or even rupture of the bag body 11 due to extrusion. In addition, the bottom surface of the gas cushion pad 14 is connected to a cross-shaped support plate 25 to strengthen the support capacity of the gas cushion pad 14, so that the gas cushion pad 14 is not easily extruded and deformed when the bag body 11 is subjected to downward extrusion. When the anti-extrusion plastic woven bag is not used to fill materials, the gas cushion pad 14 and the anti-extrusion air bags 13 can be deflated through the gas nozzle 16, and the bag body 11 can be folded to reduce the space occupancy of the anti-extrusion plastic woven bag.

[0028] In addition, the sealing assembly comprises a plurality of buckles 19, which are fixed on the upper side of the side wall of the inner cavity 12. After the filling of materials is completed, the buckles 19 are buckled to close the opening of the inner cavity 12, thereby preventing the filled materials from leaking out of the inner cavity 12. In addition, the buckles 19 are arranged in two rows on the side wall of the inner cavity 12, and the buckles 19 in the upper and lower rows are staggered, thereby further preventing the filled materials from leaking out of the inner cavity 12.

[0029] It should be pointed out that the terms such as "front", "back", "vertical", "horizontal", etc. indicated in the utility model indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the protection scope of the utility model.

[0030] The above merely describes the preferred embodiments of the utility model and is not used to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
