Description

Technical Field

[0001] The utility model relates to the technical field of sealing devices, in particular to an air bag support bag sealing device. Background Art

[0002] In industrial production, materials used in different fields are produced. After the materials are produced, most of them need to be packed in bags. First, it is convenient to store and place the materials. Second, it is also convenient for the subsequent transportation of the materials. The overall packaging cost of the bag filling method is also low. It is widely used. When the bag is used for filling, a clamping device is needed to clamp the bag to facilitate the subsequent filling work. However, the prior art has the following shortcomings when used:

[0003] Most bag clamping mechanisms use rigid clamping, and there is inevitably a gap between the bag opening and the clamping device. When loading, dust cannot be avoided from leaking. The leaked dust will affect the health of the workers and pollute the environment, and the effect is poor in actual use.

[0004] Therefore, an air bag support bag sealing device is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that most of the existing bag clamping mechanisms for the bag body adopt rigid clamping, and a gap is inevitably present between the bag mouth and the clamping device. When loading, dust cannot be avoided from leaking. The leaked dust will affect the health of the staff and pollute the environment, and the effect is poor in actual use.

[0006] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0007] An air bag support and sealing device is provided to improve the above problems.

[0008] The specific application is as follows:

[0009] An airbag bag sealing device comprises an inner tube, a flange is fixedly sleeved on the inner tube, an outer tube is fixedly connected to the bottom of the flange, symmetrically distributed internal threaded straight-through connectors are installed on the outer tube, a right-angle terminal joint is installed on the end of the internal threaded straight-through connector away from the outer tube, the inner diameter of the outer tube is larger than the outer diameter of the inner tube, a rubber expansion tube is sleeved on the inner tube, both ends of the rubber expansion tube are installed on the inner tube through throat clamps, symmetrically distributed lifting ears are fixedly connected to the bottom of the flange, two of the lifting ears are connected to a connecting plate through a first bolt, and a constraint tube is commonly provided at the end of the two connecting plates away from the lifting ears, a top cover is provided on the top of the inner tube, a feed pipe is fixedly connected to the top cover, a quick connector is installed on the feed pipe, and an anti-slip cloth is fixedly connected to the inner side of the constraint tube.

[0014] As a preferred technical solution of the present application, the flange is provided with mounting holes, and the number of the mounting holes is several.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] In the scheme of this application:

[0017] 1. The mouth of the packaging bag is sleeved between the rubber expansion tube and the constraint tube, and the direction is changed by an electrically controlled solenoid valve. The positive pressure air enters between the rubber expansion tube and the inner tube after passing through the right-angle terminal joint and the internal thread straight-through connector. The rubber expansion tube is inflated by the gas, so that the bag is fully opened, and the bag mouth is tightly clamped between the rubber expansion tube and the constraint tube. After the bag mouth is clamped, the external feeding equipment is connected to the feeding pipe through the quick-release joint, and the material is fed into the inner tube through the external feeding equipment. The material enters the packaging bag through the opening at the bottom of the inner tube, and automatic loading is realized. The raised dust has no leakage gap, and the dust is completely sealed to avoid dust damage to the operator's body and no dust pollution. The problem that most of the bag clamping mechanisms for the bag body in the prior art adopt hard clamping, and there is inevitably a gap between the packaging bag mouth and the clamping device. When loading, dust cannot be avoided from leaking. The leaked dust will affect the health of the staff and pollute the environment, and the effect is poor in actual use.

[0018] 2. Through the anti-skid cloth, when the rubber expansion tube is inflated by the gas and the bag mouth is fully opened, the rubber expansion tube fits against the inner wall of the packaging bag, and the anti-skid cloth fits against the outer wall of the packaging bag. The bag mouth is tightly clamped between the rubber expansion tube and the restraint cylinder. When the bottom of the packaging bag is not in contact with the ground, the packaging bag is prevented from slipping between the rubber expansion tube and the anti-skid cloth when loading, thereby ensuring normal loading.

[0034] like Figure 1 As shown, a retaining ring 13 is fixedly connected to the bottom of the inner tube 1.

[0035] like Figure 1 As shown, the inner diameter of the restraining tube 11 is larger than the outer diameter of the inner tube 1 , which facilitates placing the bag opening between the restraining tube 11 and the rubber expansion tube 6 .

[0038] The electrical control solenoid valve mentioned in this application can adopt existing technology products, and the working principle of the electrical control solenoid valve will not be described in detail here.

[0039] Specifically, when the airbag bag expansion and sealing device is in use: the operator puts the bag mouth of the packaging bag between the rubber expansion tube 6 and the constraint tube 11, uses the electrically controlled solenoid valve in conjunction with the right-angle terminal joint 5, and through the electrically controlled solenoid valve reversal, the positive pressure air passes through the right-angle terminal joint 5 and the internal thread straight-through connector 4 and then enters between the rubber expansion tube 6 and the inner tube 1, and the rubber expansion tube 6 is inflated by the gas to produce deformation, so that the bag is completely expanded, and the bag mouth is tightly clamped between the rubber expansion tube 6 and the constraint tube 11.
