DETAILED DESCRIPTION

[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0024] See also Figure 1 —4. An automatic filling device for chemical product slurry, which can complete filling when the filling head 2 is misaligned with the filling port, thereby improving the filling efficiency of liquid products and reducing leakage. The device includes a filling machine body 1, to which the filling head 2 is connected. The outer side of the filling head 2 is provided with a fixed tube 3 connected to the filling machine body 1, and the bottom of the fixed tube 3 is fixed with multiple groups of swing mechanisms 4 distributed in a circular array. A capping mechanism 5 is also installed at the bottom of the filling head 2.

[0025] Specifically, the filling machine body 1 is a conventional model in the prior art. By driving the filling head 2 up and down, the filling head 2 can be extended into the filling port to perform the filling operation. The filling head 2 is connected to the filling machine body 1 with a flexible pipe so that the filling head 2 can be deflected in all directions.

[0026] The fixed tube 3 is connected to the output end of the lifting structure of the filling machine body 1. The lifting mechanism of the filling machine body 1 drives the fixed tube 3 to rise and fall, and then synchronously drives the filling head 2 located inside the fixed tube 3 to rise and fall, thereby completing the filling. The fixed tube 3 is specifically a cylindrical structure. A swing mechanism 4 is fixedly provided on the outer wall of the end of the fixed tube 3. Specifically, the swing mechanism 4 includes a fixed block 41 fixed to the bottom of the fixed tube 3. An elastic member is provided in the fixed block 41 and is slidably connected to a slider 44 through the elastic unit. One end of the slider 44 is rotatably connected to The movable block 46 is fixed with an arc-shaped clamping block 47, which is clamped on the outer wall of the filling head 2. When the filling head 2 descends in the case of being misaligned with the filling port on the tank body, since the filling head 2 is movably connected to the inside of the fixed tube 3 through the swing mechanism 4, the filling head 2 can maintain a certain range of free movement inside the fixed tube 3. When misaligned, the filling head 2 first enters the filling port. Under the action of the swing mechanism 4, the filling head 2 is deviated from the center, and the front end of the filling head 2 can be completely entered into the filling port to complete the filling and prevent splashing.

[0027] Specifically, the elastic unit includes a guide rod fixed on the inner side of the fixed block 41, the guide rod is slidably connected to the slider 44, and a spring 43 is sleeved on the outer wall of the guide rod. Under the elastic force of the spring 43, the filling head 2 can move freely in the fixed tube 3.

[0028] like Figure 4 As shown, a limiting ring 23 is fixed on the top of the fixing ring 22, and the limiting ring 23 is used to abut against the clamping block 47 to prevent the filling head 2 from falling.

[0029] The utility model is provided with a swing mechanism 4, which drives the clamping block 47 to clamp and contact the filling head 2 under the action of the elastic unit, so that when the filling head 2 is inserted into the filling port of the filling barrel, when the filling head 2 is misaligned with the filling port, the filling head 2 is deflected after abutting with the filling port, so that the filling head 2 can smoothly enter the filling barrel for filling. When the filling is completed, the filling head 2 rises and then resets to the middle under the action of the elastic unit, so that filling can be completed when the filling head 2 is misaligned with the filling port, thereby improving the filling efficiency of liquid products and reducing leakage.

[0030] As an embodiment provided by the present invention, Figure 2 and Figure 4As shown, the capping mechanism 5 includes a driving unit 51 installed at the bottom of the fixed ring 22. The telescopic shaft of the driving unit 51 is hinged to the side wall of the rotating cover 53 through a connecting rod 52. The rotating cover 53 is provided at the bottom of the material tube 21. The rotating cover 53 is rotatably connected to the fixed seat 54, and the fixed seat 54 is installed at the bottom of the fixed ring 22. Specifically, the driving unit 51 adopts any one of an electric push rod, a hydraulic rod or a cylinder. The driving unit 51 works and the rotating cover 53 is flipped under the action of the connecting rod 52, thereby closing or opening the filling head 2 to prevent the slurry remaining in the filling head 2 from leaking out after the filling is completed.

[0031] As a further embodiment provided by the present invention, Figure 4 As shown, the filling head 2 includes a material tube 21, a fixed ring 22 is fixedly provided on the outer wall of the material tube 21, a closed ring 25 is fixedly provided at the bottom of the fixed ring 22, an arc-shaped rubber ring 24 is installed on the inner side of the closed ring 25, and the arc-shaped rubber ring 24 is provided on the closed ring 25. The outer diameter of the arc-shaped rubber ring 24 is larger than the diameter of the filling head 2, so that the arc-shaped rubber ring 24 can seal the filling port to a certain extent during the filling process, thereby preventing the slurry from splashing to the outside of the tank body during the filling process.

[0032] The elastic coefficient of the elastic unit mentioned in this article meets the technical requirements of the technical solution of the present utility model.

[0033] Those skilled in the art will appreciate that other similar connection methods can also implement the present invention, such as welding, bonding, or screwing.

[0034] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
