Description

Technical Field

[0001] The utility model relates to the technical field of cement packaging, in particular to a cement packaging bag. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material. It becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly bond sand, stone and other materials together. The early mixture of lime and volcanic ash is very similar to the modern lime volcanic ash cement. It is used to bond concrete made of crushed stone. After hardening, it not only has high strength, but also can resist the erosion of fresh water or salt water. For a long time, it has been used as an important gelling material and is widely used in civil construction, water conservancy, national defense and other projects. Cement needs to be packaged in cement bags during transportation.

[0003] The existing cement bags are usually sewn with ropes. When in use, the ropes on the cement bags need to be cut or the cement bags need to be torn, resulting in that the cement bags can only be used once. In addition, the existing cement bags have poor wear and water resistance. When the cement bags come into contact with water, the cement inside the cement bags will clump. When the cement bags are worn, the cement in the cement bags will leak. When adding cement to the inside of the cement packaging bags, since the bag material is relatively soft, workers need to lift it up after filling some cement before they can continue to add cement, resulting in low work efficiency. Therefore, a cement packaging bag is proposed to address the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a cement packaging bag to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cement packaging bag comprises a packaging bag body, wherein a support frame is provided inside the packaging bag body, wherein the support frame comprises side rods which are vertically arranged and located inside the packaging bag, wherein the top ends of the side rods are fixedly connected to horizontally arranged top rods, and below the top rods there is a bottom rod which is horizontally arranged and fixedly connected to the bottom ends of the side rods, and a sealing device is provided at the top end of the packaging bag body.

[0007] Preferably, the packaging bag body comprises a polyester anti-wear layer, one side of the polyester anti-wear layer is fixedly connected to a waterproof plastic layer, and a tensile fiber rope is fixedly connected between the polyester anti-wear layer and the waterproof plastic layer.

[0008] Preferably, there are a plurality of tensile fiber ropes, and the tensile fiber ropes are distributed in an array between the polyester anti-wear layer and the waterproof plastic layer, and the top rod and the bottom rod are the same in shape and size.

[0009] Preferably, the sealing device includes a horizontally arranged first clamping rod, a sealing groove is provided on one side of the first clamping rod, a second clamping rod is provided on the side of the first clamping rod close to the sealing groove, a sealing strip is provided on the side of the second clamping rod close to the sealing groove, a limiting frame is symmetrically provided on the outer side of the first clamping rod and is fixedly connected to the outer side of the first clamping rod, a screw rod is provided on one side of the limiting frame and passes through the limiting frame and is spirally connected to the limiting frame, one end of the screw rod is fixedly connected to a handle, and a bearing is fixedly connected to the side of the screw rod away from the handle.

[0010] Preferably, the first clamping rod and the second clamping rod are of the same shape and size, the second clamping rod is connected to the limit frame by sliding connection, and the side of the bearing away from the screw rod is fixedly connected to the second clamping rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, the wear-resistant, waterproof and tear-resistant performance of the packaging bag can be increased by providing the polyester anti-wear layer, the waterproof plastic layer and the tensile fiber rope, and the service life of the device can be increased. Due to the good stability of polyester and its tight fabric structure, when the packaging bag body rubs against the external object, the outermost polyester anti-wear layer can maintain structural integrity. Due to the compactness and impermeability of the plastic, rainwater can be prevented from seeping into the packaging bag body when it rains. The tensile fiber rope can provide good tear-resistant performance, preventing the packaging bag body from being burst due to excessive cement weight.

[0013] 2. In the utility model, the supporting frame, side bars, top bars and bottom bars are provided to support the packaging bag body, so that it is more convenient for workers to add cement to the inside of the packaging bag body. The bottom bar enables the packaging bag body to be placed upright. When adding cement, the cement can be directly poured into the inside of the top bar at the top of the side bar, without the need for workers to repeatedly lift and pull;

[0014] 3. In the utility model, the sealing device, the first clamping rod, the sealing groove, the second clamping rod, the sealing strip, the limiting frame, the screw, the handle and the bearing are provided, so that the sealing of the packaging bag body is more convenient and can be used repeatedly. When sealing is required, the opening of the packaging bag body is placed inside the first clamping rod and the second clamping rod, and then the handle is turned. Due to the limitation of the limiting frame and the bearing, the screw can drive the second clamping rod to move in the direction of the first clamping rod until the sealing strip and the sealing groove press the opening of the packaging bag, and the sealing of the packaging bag body is completed. When cement is needed, the sealing device can be removed by directly reversing the handle to take out the cement inside the packaging bag body. BRIEF DESCRIPTION OF THE DRAWINGS
