[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.
[0024] The following describes in detail, with reference to the accompanying drawings, a filling head structure for a vial filling machine according to an embodiment of the present invention.
[0025] Example 1
[0026] For easier understanding, please refer to Figures 1 to 4 This utility model provides an embodiment of a filling head structure for a vial filling machine, including a filling head body 1, a filling tube 2 fixedly installed at the output end of the filling head body 1, and a rotating discharge assembly provided at the output end of the filling tube 2.
[0027] The rotary discharge assembly includes a fixed head 301, a fixed pipe 302, a waterproof bearing 303, a fixed nut 304, a meshing thread 305, a rotary housing 306, and several discharge pipes 307. The fixed head 301 is fixedly installed at one end of the filling pipe 2, the fixed pipe 302 is fixedly connected to one end of the fixed head 301, the waterproof bearing 303 is sleeved on the outer wall of one end of the fixed pipe 302, the meshing thread 305 is formed in the middle of the fixed pipe 302, the fixed nut 304 is threadedly connected to the meshing thread 305, and one end of the rotary housing 306 is fixedly installed on the waterproof bearing 303. On the outer wall, several discharge pipes 307 are fixedly connected to the side wall of the rotating housing 306. One side of the fixing nut 304 abuts against one side of the waterproof bearing 303. The waterproof bearing 303 is fixedly installed on the outer wall of the fixing pipe 302 through the cooperation of the fixing nut 304 and the meshing thread 305. Several discharge pipes 307 are all connected to the inside of the rotating housing 306. The tangent angle between the shaft of the discharge pipe 307 and the rotating housing 306 is 30-45 degrees. The outer wall of the output end of the filling pipe 2 is provided with external threads. The fixing head 301 is threadedly connected to the external thread of one end of the filling pipe 2.
[0028] It should be noted that a rotating outer shell 306 with a discharge pipe 307 is fixedly installed on the outside of the waterproof bearing 303. During filling, the filling pipe 2 discharges, and the liquid is discharged from the discharge pipe 307 on the side wall of the rotating outer shell 306. Under the reaction force of the liquid discharge, the rotating outer shell 306 is pushed to rotate, generating a rotating flow during the filling process. This helps the components in the solution to be more evenly distributed in the vial, reducing the possibility of solution stratification or precipitation.
[0029] Example 2
[0030] In some embodiments, such as Figure 2 , Figure 4As shown, the rotary discharge assembly also includes a filter screen 308. One end of the filter screen 308 is fixedly connected to one end of the fixing nut 304. The filter screen 308 is located inside the rotary housing 306 and is sleeved on the outer wall of the fixing tube 302.
[0031] It should be noted that by setting up filter screen 308, the impurities, particles, and any foam that may be generated in the solution can be effectively filtered out, which helps to ensure that the filled solution is pure and uncontaminated, thereby improving the quality of the product.
[0032] Working principle: During filling, the filling tube 2 discharges liquid through the discharge tube 307 on the side wall of the rotating shell 306. The reaction force of the liquid discharge drives the rotating shell 306 to rotate, generating a rotating flow during the filling process. This helps the components in the solution to be more evenly distributed in the vial, reducing the possibility of solution stratification or precipitation. At the same time, the filter screen 308 effectively filters out impurities, particles, and any foam that may be generated in the solution, helping to ensure that the filled solution is pure and uncontaminated, thereby improving product quality.
