Since there is a certain gap between the bottle mouth and the filling head, and the filling head is usually filled vertically downward, it is easy for the chemical liquid material to splash out during the filling process, causing certain waste. In view of this, the present utility model is specially proposed. Utility Model Content

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 4A filling device for chemical liquid materials, comprising a storage box 1, and further comprising: a suction cylinder 3, fixedly mounted at the lower end of one side of the storage box 1, the feed port of the suction cylinder 3 and the discharge port of the storage box 1 being connected via a delivery pipe 101; a piston block 301, slidably connected in the suction cylinder 3; a driving mechanism for driving the piston block 301 to move up and down in the suction cylinder 3, mounted on the storage box 1; a filling pipe 304, connected to the discharge port of the suction cylinder 3 via a telescopic hose 303; an electric telescopic rod 308, symmetrically fixed Installed on the storage box 1 on both sides of the suction cylinder 3, the telescopic ends of the two electric telescopic rods 308 are fixedly connected to the filling tube 304 through the connecting bracket 307; the elastic membrane 305 is fixedly connected to the opening at the lower end of the filling tube 304, and the elastic membrane 305 is provided with a plurality of discharge ports equidistantly arranged in a circle; the filling head 306 is fixedly connected to the discharge port of the elastic membrane 305, and the feed port of the suction cylinder 3 and the filling head 306 are both equipped with a one-way valve; a limit assembly for fixing the storage bottle is installed at the lower end of the bracket 307.

[0022] The driving mechanism includes a screw rod 2, a motor 201, a limit rod 202, a moving block 203 and a connecting rod 204. The screw rod 2 is rotatably connected to one side of the storage box 1 close to the suction cylinder 3. The limit rod 202 is symmetrically fixedly connected to the two sides of the storage box 1 close to the screw rod 2. The motor 201 is fixedly connected to the upper end of the storage box 1, and the output end is fixedly connected to the upper end of the screw rod 2. The moving block 203 is slidably connected to the two limit rods 202 and is threadedly connected to the screw rod 2. The two ends of the connecting rod 204 are respectively fixedly connected to the moving block 203 and the piston block 301.

[0023] The limiting assembly includes a limiting ring 4, a T-bar 401 and a tensioning spring 402. The T-bar 401 is symmetrically and slidingly connected to both sides of the bracket 307. The limiting ring 4 is fixedly connected to the lower ends of the two T-bars 401. The inner diameter of the limiting ring 4 is larger than the outer diameter of the filling tube 304. The tensioning spring 402 is sleeved on the T-bar 401, and its two ends are fixedly connected to the bracket 307 and the limiting ring 4 respectively.

[0024] When the chemical liquid material is produced and needs to be filled into the storage bottle for storage, the device is first fixed on the top of the conveyor belt through the mounting frame. Then, when the conveyor belt transports the cleaned and disinfected storage bottle to the bottom of the filling tube 304, the movement of the storage bottle can be stopped. Then, the electric telescopic rod 308 can be started. The electric telescopic rod 308 will drive the filling tube 304 to move downward through the bracket 307. When the bracket 307 drives the filling tube 304 to move downward, it will also drive the limit ring 4 to move downward through the T-bar 401 and the tension spring 402. When the limit ring 4 is sleeved on the outside of the storage bottle and abuts against the storage bottle, the bracket 307 continues to be controlled. 07 moves down, and then the bracket 307 will compress the tensioning spring 402, so that the limiting ring 4 can be tightly against the storage bottle, and the storage bottle is limited and fixed. At the same time, when the bracket 307 moves down to compress the tensioning spring 402, it will also drive the filling tube 304 to continue to move down, so that the filling tube 304 can be extended into the storage bottle, and then the motor 201 can be started to make the motor 201 drive the moving block 203 to move up through the screw rod 2, and the moving block 203 will drive the piston block 301 to move up a certain distance through the connecting rod 204, so that the chemical liquid material in the storage box 1 can be quantitatively sucked into the suction cylinder 3 through the feeding pipe 101. Then, the motor 201 can be used to reversely drive the screw rod 2, and then the piston block 301 can be controlled to move downward, so that the chemical liquid material is squeezed into the filling tube 304 through the telescopic hose 303. Since a one-way valve is arranged in the filling head 306, a certain pressure is required to conduct it. Then, when the chemical liquid material applies pressure to the one-way valve, it also applies pressure to the elastic membrane 305. Then, the elastic membrane 305 will be deformed into an arc shape under the pressure of the chemical liquid material, and then the filling head 306 fixed on the elastic membrane 305 will also tilt accordingly, and then the discharge port of the filling head 306 will be inclined downward to face the inner wall of the storage bottle, and then when the filling When the one-way valve in the filling head 306 is opened, the chemical liquid material will be sprayed obliquely downward onto the inner wall of the storage bottle through the discharge port of the filling head 306, thereby filling the storage bottle with the chemical liquid material. Compared with the method of directly spraying the chemical liquid material downward in the prior art, it can prevent the falling chemical liquid material from splashing out of the storage bottle due to the strong impact force with the chemical liquid material in the storage bottle, causing a certain amount of waste. In addition, by limiting and fixing the storage bottle, it can also prevent the storage bottle from shaking or even tipping over under the impact of the chemical liquid material, resulting in the outflow of chemical liquid and the occurrence of waste, thereby effectively ensuring the stability of the storage bottle.

[0025] When the filling of the storage bottle is completed, the storage bottle can be moved out of the filling tube 304 through the electric telescopic rod 308, and then the limit ring 4 will be separated from the storage bottle. Then the conveyor belt can be started again to transport the filled storage bottle away and move the next empty bottle to the bottom of the filling tube 304. This process can be repeated to continuously fill the chemical liquid material.

[0026] Embodiment 2:

[0027] Reference Figure 1-Figure 4 , a filling device for chemical liquid materials, which is basically the same as embodiment 1, and further: the inner wall of the limit ring 4 is provided with an arc chamfer, and the inner wall of the limit ring 4 is designed to be arc-shaped, such as Figure 4 As shown, when the limiting ring 4 is clamped on the outer wall of the storage bottle, it can protect the storage bottle and prevent the limiting ring 4 from scratching the outer wall of the storage bottle.

[0028] The discharge port of the filling head 306 is opened at the lower end of one side of the filling head 306. By setting the discharge port of the filling head 306 at the lower end of one side, as shown in FIG. Figure 4 As shown, a certain angle can be formed between the discharge port of the filling head 306 and the bottle wall of the discharge bottle, so that when the chemical liquid material is filled into the storage bottle through the filling head 306, the chemical liquid material can be prevented from being directly sprayed vertically toward the bottle wall, thereby causing splashing, thereby further reducing the splashing of the chemical liquid material.

[0029] The opening at the upper end of the suction cylinder 3 is fixedly connected to a rangefinder 302 through a support plate, and the detection end of the rangefinder 302 faces downward to the piston block 301. Through the setting of the rangefinder 302, the upward movement height of the piston block 301 can be monitored in real time, so that the content of the chemical liquid material sucked into the suction cylinder 3 can be judged according to the upward movement height of the piston block 301, thereby facilitating more accurate filling.
