Description

Technical Field

[0001] The utility model relates to the field of canning heads of glue filling machines, in particular to a canning head device of a glue filling machine with independent gas and liquid packaging. Background Art

[0002] The filling head of the glue filling machine is a key component of the glue filling machine. It is mainly responsible for accurately pouring glue into a specific position. During the glue filling process, the filling head controls the outflow volume, outflow speed and outflow direction of the glue to ensure that the glue can be poured according to the predetermined requirements to achieve precise glue filling operations. The original action before canning is that the filling head will first go down to the bottom of the bottle to fill with nitrogen to replace the air in the bottle, and then start filling the medicine after 5 seconds of nitrogen filling. Nitrogen forms a nitrogen curtain protection at the filling port, and the filling head slowly rises with the liquid level. When the canning is completed, the back suction valve sucks back the residual liquid. Because it is a non-independent pipeline, when nitrogen is added, the residual liquid will be blown back into the bottle, which may cause bubbles to form, or affect the actual weighing weight. Therefore, a canning head device with independent gas and liquid encapsulation for the glue filling machine is needed.

[0003] The existing canning head device is inconvenient to independently package gas and liquid during use, which causes bubbles to be generated during the filling process, thereby affecting the quality of the filling production. Therefore, a canning head device for the glue filling machine that can independently package gas and liquid is urgently needed. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a canning head device for independent gas and liquid packaging of a glue filling machine, so as to solve the problem that the existing canning head device is inconvenient to independently package gas and liquid.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a canning head device with independent gas-liquid packaging for a glue filling machine, comprising a first filling connector, a second filling connector installed on the top of the first filling connector, a bolt installed inside the second filling connector, an O-ring installed inside the second filling connector, a PFA filling hose installed at the bottom of the second filling connector, a nitrogen outer sleeve installed inside the first filling connector, and a third filling connector installed at the bottom of the first filling connector.

[0006] A fixing frame is installed on the outer wall of the first filling connector, a protective cover is fixedly connected to the outer wall of the fixing frame, and a back-suction valve is installed inside the protective cover.

[0007] Preferably, threaded holes are provided inside the first filling connector and the second filling connector, and the bolt is threadedly connected to the first filling connector.

[0008] Preferably, the first filling connector is snap-connected to the second filling connector, and an O-ring is located between the first filling connector and the second filling connector.

[0009] Preferably, the PFA filling hose is plugged into the second filling connector, and the second filling connector is of open-hole design.

[0010] Preferably, the nitrogen outer sleeve is sleeved on the outer wall of the PFA filling hose, and the third filling connector is welded to the first filling connector by a welding rod.

[0011] Preferably, the first filling connector is threadedly mounted on the fixing frame, and the top of the second filling connector is connected to the back-suction valve.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model is provided with a first filling connector, a second filling connector, a bolt, an O-ring, a PFA filling hose and a nitrogen outer sleeve. By placing the O-ring between the first filling connector and the second filling connector, passing the bolt through the second filling connector and rotating it, the first filling connector and the second filling connector can be sealed and installed. Since the PFA filling hose is installed at the bottom of the second filling connector, the filling liquid can flow through the second filling connector and be discharged through the PFA filling hose. Since the nitrogen outer sleeve is hollow and is sleeved on the outside of the PFA filling hose, the filling liquid can be injected through the PFA filling hose, and the nitrogen can be injected through the nitrogen outer sleeve, which facilitates the independent packaging of gas and liquid and prevents the generation of bubbles during the filling process.

[0014] 2. The utility model provides a first filling connector, a fixing frame, a protective cover and a back-suction valve. By installing the first filling connector on the fixing frame and connecting the top of the second filling connector to the back-suction valve, since the first filling connector, the fixing frame and the back-suction valve are all located in the protective cover, the integrity of the device can be improved, and the overall aesthetics and technological features can be enhanced.
