[0020] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present utility model as follows.

[0021] Embodiment: Please refer to Figure 1-2 , an aluminum tube filling, sealing and hemming device for filling creams, comprising a frame 5 and a storage tank 4 installed on the frame 5. The top of the storage tank 4 is connected to a nitrogen gas balloon through an exhaust flexible hose 7. The exhaust flexible hose 7 is connected to the air extraction pipe of an air extraction pump 10 through a branch pipe. The exhaust pipe of the air extraction pump 10 is connected to the nitrogen gas balloon. A first valve 8 is provided on the exhaust flexible hose 7 between the nitrogen gas balloon and the branch pipe, and a second valve 9 is provided on the branch pipe. The first valve 8, the second valve 9 and the air extraction pump 10 are all connected to a controller. The top of the storage tank 4 is connected to the discharge flexible hose 1 of the material supply system. Among them, the material supply system uses a cream pump to pump the cream into the relevant structure inside the storage tank 4. As long as the structure can realize injecting the cream into the storage tank 4, it will not be elaborated too much in this article; since the storage tank 4 in this utility model is isolated from the outside world, therefore, the pollution of the cream is reduced and the quality of the cream is guaranteed; when it is necessary to inject the cream into the storage tank 4, the controller only needs to control the first valve 8 to close, the second valve 9 to open, and then start the air extraction pump 10 to extract the air inside the storage tank 4. Then, the material supply system can be started to inject the cream into the storage tank 4. At this time, the inside of the storage tank 4 is in a negative pressure state and there is no air, so that it can prevent the cream from being easily mixed with air when poured into the storage tank 4, thereby improving the filling quality of the cream; in addition, since the inside of the storage tank 4 is isolated from the outside world, when the amount of cream in the storage tank 4 decreases, a negative pressure will occur inside the storage tank 4, which is not conducive to the discharge of the cream at this time. Therefore, in this embodiment, a nitrogen gas balloon is provided. After the storage tank 4 is filled with cream, the first valve 8 will open, and the nitrogen gas in the nitrogen gas balloon will enter the top of the storage tank 4. As the cream decreases, the atmospheric pressure will squeeze the nitrogen gas balloon, thereby filling nitrogen into the storage tank 4, so as to ensure that the inside of the storage tank 4 is consistent with the outside atmospheric pressure, which is conducive to the discharge of the cream and at the same time prevents the internal air pressure from being too large, so as to prevent the nitrogen gas from being pressed into the cream and causing the generation of bubbles.

[0022] In this embodiment, an exhaust pipe is provided with a bleed-off pipe, and a third valve is provided on the bleed-off pipe. A fourth valve is provided on the exhaust pipe between the bleed-off pipe and the nitrogen gas bag. Both the third valve and the fourth valve are connected to the controller. When the storage tank 4 is evacuated for the first time, the first valve 8 and the fourth valve are both closed, and the second valve 9 and the third valve are opened, so as to discharge the air inside the storage tank 4 into the atmosphere, preventing the air pollution inside the storage tank 4 from contaminating the nitrogen gas in the nitrogen gas bag. In subsequent evacuations, the third valve will always remain closed, so that the nitrogen gas can be recycled, saving resources.

[0023] A motor 3 is provided on the top of the storage tank 4. The output end of the motor 3 penetrates through the top of the storage tank 4. A stirring rod is fixedly connected to the output end of the motor 3. The stirring rod is located inside the storage tank 4. Since nitrogen gas is located at the top of the storage tank 4, that is, at the top of the cream, and then the nitrogen gas pressure is consistent with the outside world, but to ensure that there are no bubbles inside the cream. Therefore, at regular intervals, the controller will control the first valve 8 to close, and the second valve 9 and the fourth valve to open. Then the air pump 10 is started to pump the nitrogen gas inside the storage tank 4 back into the nitrogen gas bag. During this process, the motor 3 will be started to make the stirring rod stir the cream, facilitating the discharge of the bubbles inside the cream. When all the bubbles are discharged, the second valve 9 and the fourth valve will close, and the first valve 8 will open. The air pump 10 and the motor 3 will also stop working. At this time, the nitrogen gas flows back into the inner top of the storage tank 4 under the action of the atmospheric pressure, preventing a negative pressure from occurring inside the storage tank 4, which is not conducive to the discharge of the cream.

[0024] In this embodiment, a through hole is provided on the frame 5. The outer wall of the storage tank 4 is slidably connected to the through hole. The bottom of the storage tank 4 is connected to a metering pump installed on the frame 5 through a transition hose. A support ring plate 2 is provided on the upper part of the storage tank 4. A weighing module 11 communicated with the controller is fixedly connected to the frame 5. The support ring plate 2 abuts against the detection end of the weighing module 11, facilitating the detection of the content of the cream in the storage tank 4 and timely supplementing the cream. At the same time, several weight levels can be set, that is, when the amount of the cream decreases by one-third each time, the motor 3 and the air pump 10 will be started once, so as to discharge the bubbles inside the cream. In addition, a heating cavity for heating the outer wall temperature of the storage tank 4 is provided between the through hole and the outer wall of the storage tank 4. The inside of the heating cavity is communicated with a hot water circulation system. Among them, the hot water circulation system adopts a common hot water supply system, that is, the storage tank 4 is heated by water bath, so as to facilitate the uniform heating of the cream inside the storage tank 4. While facilitating the discharge of bubbles, for creams with a relatively high viscosity, the viscosity will relatively decrease after heating, facilitating the filling of the cream.

[0025] The device further includes an aluminum tube feeding mechanism mounted on the frame 5 through an angle adjusting mechanism 12. The aluminum tube feeding mechanism is used to place aluminum tubes into the rotating disk 6 in the filling mechanism. The metering pump is mounted on the filling mechanism. A tail sealing mechanism for tail sealing and flanging the filled aluminum tubes is also provided on the frame 5. Among them, the aluminum tube feeding mechanism, the filling mechanism, and the tail sealing mechanism all adopt common existing mechanisms, and will not be elaborated too much in this article. The angle adjusting mechanism 12 includes a support table 19 and a support column 17 fixedly connected to the frame 5. The support table 19 is hinged to the bottom of the storage frame 14 in the aluminum tube feeding mechanism. A sliding block 13 is slidably connected to the bottom of the storage frame 14. The top of the support column 17 is rotatably connected to a driving column 16. The inner hole of the driving column 16 is threadedly connected to a screw 15. One end of the screw 15 is located inside the support column 17, and the other end of the screw 15 is fixedly connected to a cross bar 20. Support ears rotatably connected to both ends of the cross bar 20 are fixedly connected to the sliding block 13, so that the angle of the storage frame 14 can be adjusted, thereby improving the feeding speed of the aluminum tubes and further improving the filling efficiency of the device. A plurality of handles 18 are provided on the outer circumference of the driving column 16 to facilitate the rotation of the driving column 16. The above-mentioned rotatable connection method can adopt a socket form.

[0026] Working principle: When the cream is first injected into the storage tank 4, the first valve 8 and the fourth valve are closed first, and the second valve 9 and the third valve are opened. Subsequently, the air pump 10 is started to discharge the air inside the storage tank 4 into the atmosphere. Then, the material supply system is started to inject the cream into the storage tank 4. When the injection stops, the second valve 9, the third valve and the fourth valve are closed, and the first valve 8 is opened. The nitrogen in the nitrogen gas bag will enter the top of the storage tank 4, so as to ensure that the inside of the storage tank 4 is consistent with the external atmospheric pressure, which is beneficial to the discharge of the cream. At the same time, it prevents the internal air pressure from being too high, so as to press the nitrogen into the cream and cause the generation of bubbles.

[0027] When the cream is injected into the storage tank 4 again after the first time, the third valve is in a normally closed state. The controller only needs to control the first valve 8 to close, and the second valve 9 and the fourth valve to open. Subsequently, the air pump 10 is started, and the nitrogen inside the storage tank 4 will flow back into the nitrogen gas bag. Then, the material supply system can be started to inject the cream into the storage tank 4. When the injection stops, the second valve 9 and the fourth valve are closed, and the first valve 8 is opened. The nitrogen in the nitrogen gas bag will enter the top of the storage tank 4 again.
