[0026] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] Reference Figures 1 to 3 As shown, the utility model provides a bag opening supporting device for a packaging bag, comprising: a supporting tube 1, a blanking tube 2, and an elastic film layer 3.

[0029] In this embodiment, the support tube 1 is arranged vertically and has a closed upper end and an open lower end.

[0030] The drop tube 2 is arranged inside the support tube 1. In this embodiment, the drop tube is coaxially arranged in the support tube.

[0031] The drop pipe 2 is arranged vertically. The drop pipe 2 has an upper feed opening and a lower discharge opening for installing a powder conveying pipeline. The upper feed opening penetrates the closed upper end and extends to the outside of the closed upper end.

[0032] An exhaust ring cavity b is formed between the outer wall of the blanking tube 2 and the interior of the support tube 1. The outer diameter of the blanking tube is smaller than the inner diameter of the support tube. The difference between the outer diameter of the blanking tube and the inner diameter of the support tube is the thickness of the exhaust ring cavity.

[0033] An exhaust hole a is formed on the upper portion of the support tube 1. An air filter is installed in the exhaust hole a. In this embodiment, exhaust holes are formed on opposite sides of the upper portion of the support tube.

[0034] The outer wall of the lower part of the support tube 1 is formed with two flange plates 11. The two flange plates are arranged at intervals along the axial direction of the support tube. Each flange plate 11 is arranged along the circumferential direction of the support tube 1 for one circle.

[0035] The elastic membrane layer 3 is connected to the two flange plates 11. A sealed cavity c is formed between the elastic membrane layer 3, the two flange plates 11 and the outer wall of the support tube 1. The width of the flange plate is the thickness of the sealed cavity.

[0036] The flange plate 11 is provided with a pressurizing port and a pressure relief port. Electric valves are installed in the pressurizing port and the pressure relief port, respectively. In this embodiment, one flange plate is provided with a pressurizing port, and the other flange plate is provided with a pressure relief port. The pressurizing port is connected to an air source, such as an air compressor, through a pipeline. The elastic film layer 3 is used for the bag opening of the packaging bag to be set.

[0037] As a preferred embodiment, the elastic membrane layer 3 is a rubber membrane layer. Specifically, the rubber membrane layer is made of silicone rubber gas phase mixed rubber (i.e., methyl vinyl silicone rubber). In this embodiment, the cross section of the rubber membrane layer is C-shaped. The upper and lower flanges of the rubber membrane layer are respectively installed on two flange plates.

[0038] The reaction ring 4 is sleeved on the outside of the elastic membrane layer 3. A gap is set between the reaction ring 4 and the elastic membrane layer 3. The reaction ring 4 is installed on the feed upper opening of the blanking pipe 2 through a supporting frame.

[0039] In this embodiment, the reaction ring 4 is disposed at the middle position of the elastic membrane layer 3 .

[0040] When filling powder into a packaging bag, the bag opening of the packaging bag is sleeved on the outside of the elastic film layer and arranged on the inner side of the reaction ring. The boost port is opened, the pressure relief port is closed, and the air source fills the sealed cavity with airflow through the boost port. The elastic film layer expands toward the reaction ring and presses the bag opening of the packaging bag against the inner side of the reaction ring, thereby supporting the bag opening of the packaging bag. When a packaging bag is filled with powder, the boost port is closed and the pressure relief port is opened, so that the airflow in the sealed cavity is discharged, and the elastic film layer is restored to its initial state, thereby releasing the support for the bag opening of the packaging bag. The operator can withdraw the bag opening of the packaging bag from between the elastic film layer and the reaction ring, and then tie it up.

[0041] The bag mouth support device for the packaging bag of the utility model forms an exhaust ring cavity between the inner side of the support tube and the blanking tube. When the powder is filled into the packaging bag through the blanking tube, the flying dust can enter the exhaust ring cavity. The exhaust ring cavity is connected to the exhaust hole, which can balance the air pressure on the one hand. In addition, the air filter in the exhaust hole can inhibit the leakage of dust. A sealed cavity is formed between the elastic film layer and the flange plate on the outer side of the support tube. By adjusting the air pressure in the sealed cavity, the elastic film layer expands toward the reaction ring, and then the bag mouth of the packaging bag is locked and supported, thereby realizing temporary sealing of the bag mouth, and the sealing effect is good.

[0042] In this embodiment, the upper feed opening is connected to the powder conveying pipeline through a flange 21 .

[0043] As a preferred implementation, the support frame includes: an adapter plate 41 and a suspension rod 42 .

[0044] There are multiple adapter plates 41. The adapter plates 41 are connected to the flange 21 on the upper feed opening. The multiple adapter plates 41 are spaced apart along the circumferential direction of the upper feed opening.

[0045] The suspension rod 42 is mounted on the adapter plate 41 . The lower end of the suspension rod 42 is connected to the reaction ring 4 .

[0046] In this embodiment, there are three adapter plates, one end of which is connected to the flange of the feed upper opening, and the suspension rod is installed at the other end of the adapter plate.

[0047] Specifically, the adapter plate 41 is provided with a through hole. The upper end of the suspension rod 42 can be movably inserted into the through hole. Two clamping members are adjustable on the upper end of the suspension rod 42. The two clamping members are clamped on the adapter plate 41.

[0048] In this embodiment, an external thread is formed on the upper end of the suspension rod 42 , a threaded hole is formed on the clamping member, and the clamping member is screwed to the upper end of the suspension rod 42 .

[0049] The bag opening supporting device for packaging bags of the present invention further comprises a movable seat 5 . The adapter plate 41 is mounted on the movable seat 5 .

[0050] Specifically, the movable seat 5 includes a plane frame 51 , a horizontal cross frame 52 , and rollers 53 .

[0051] There are three plane frames 51. Each plane frame 51 is vertically arranged. Two plane frames 51 are respectively connected to opposite sides of another plane frame 51. A roller 53 is installed at the bottom of the plane frame 51.

[0052] The horizontal cross frame 52 is connected to the top of the three-sided plane frame 51. A through hole is formed in the middle of the horizontal cross frame 52. The middle of the support pipe 1 is arranged in the through hole. The adapter plate 41 is connected to the horizontal cross frame 52.

[0053] By setting the movable seat, the bag opening supporting device for the packaging bag of the utility model can be used flexibly and moved conveniently.

[0054] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
