Description

Technical Field

[0001] This utility model belongs to the field of filling equipment technology, and in particular relates to a protein liquid filling device. Background Technology

[0002] Protein liquid is a nutritional supplement used to replenish the nutrients needed for exercise. It is mainly made from low-temperature desolventized soybean meal. Through different processing methods, soluble sugars, ash and other soluble trace components in the low-temperature meal are removed, thereby increasing its protein content.

[0003] In the production and processing of protein solutions, a filling machine is used to fill the finished protein solution into empty bottles. A filling machine is a device used to fill liquids, powders, or granular materials into containers. It is widely used in production lines in the food, beverage, cosmetics, pharmaceutical, and chemical industries. The working principle of a filling machine varies depending on the filling method; common filling methods include gravity filling, pneumatic filling, and vacuum filling.

[0004] In traditional filling technology, protein liquid filling generally requires quantitative filling, but quantitative adjustment is quite complicated, affecting the convenience of quantitative adjustment of the filling device and causing great inconvenience to the production process. In addition, after the filling head completes a single filling, protein liquid remains inside the discharge tube of the filling head. This residual protein liquid will fall downwards under the action of gravity, and in most cases it will fall directly onto the bottle or conveyor belt, which not only pollutes the bottle, conveyor belt and surrounding environment, but also wastes the product. Utility Model Content

[0005] This invention provides a protein liquid filling device with a reasonable structural design to solve the technical problems existing in the prior art. This invention has a quantitative adjustment function for quantitative filling, which improves the convenience of quantitative adjustment and prevents leakage of protein liquid after filling, avoiding resource waste and pollution to the filling environment.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A protein liquid filling device includes a mounting bracket with a storage tank installed on the top, multiple liquid outlets installed at the bottom of the storage tank, and a control valve installed at each liquid outlet; a stirring structure rotatably connected to the storage tank is installed inside the storage tank, and a stirring motor for driving the stirring structure to rotate is also included; a mounting operating platform located below the storage tank is mounted on the mounting bracket, and a measuring cylinder assembly is sealed and installed on the mounting operating platform; the measuring cylinder assembly includes multiple measuring cylinder units sealed and installed on the mounting operating platform, each measuring cylinder unit having an inlet and outlet at its upper part, and a reversing valve installed at the inlet and outlet, the reversing valve being connected to each liquid outlet of the storage tank through a liquid pipeline; and a quantitative adjustment component cooperating with the measuring cylinder assembly, the quantitative adjustment component including a lifting drive mechanism, wherein the moving end of the lifting drive mechanism... The system includes multiple piston rod structures that penetrate the mounting platform and are connected to the inner walls of multiple measuring cylinder units; it also includes an adjustable mounting assembly located above the mounting platform, on which several filling valve assemblies are mounted, with adjustable spacing between adjacent filling valve assemblies; it further includes a lifting adjustment assembly for driving the adjustable mounting assembly to move longitudinally; the filling valve assembly includes a filling valve cylinder structure with a liquid outlet and a rubber ring at the bottom, and a feed inlet connected to the upper part of the filling valve cylinder structure, which is connected to a corresponding reversing valve; it also includes a valve stem drive cylinder mounted on the upper part of the filling valve cylinder structure, with a filling valve stem installed at the extended end of the valve stem drive cylinder and passing through the filling valve cylinder structure, and a sealing head for sealing the liquid outlet of the filling valve cylinder structure installed at the lower end of the filling valve stem; and it also includes venting passages opened in the sealing head, filling valve stem, and filling valve cylinder structure.

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a protein liquid filling device. Through the arrangement of a measuring cylinder assembly, a quantitative adjustment assembly, and several filling valve assemblies, it can achieve quantitative dispensing and quantitative filling of protein liquid. By synchronously adjusting the movement distance of multiple piston rod structures through a lifting drive mechanism, quantitative adjustment of each measuring cylinder unit can be achieved, resulting in good adjustment stability and convenient, controllable protein liquid filling processing. The valve rod drive cylinder drives the filling valve rod to move up and down, thereby opening the outlet of the filling valve assembly during filling and completing the filling process. The outlet of the filling valve assembly is then sealed with a sealing head. A lifting and adjusting assembly allows several filling valve assemblies to move synchronously up and down, ensuring the outlet of the filling valve cylinder extends into the bottle neck during filling. A rubber ring on the filling valve cylinder seals the end of the bottle neck, preventing liquid from splashing onto the outside of the bottle during filling. Furthermore, venting passages on the sealing head, filling valve stem, and filling valve cylinder allow for the release of gas from the bottle during filling, ensuring smooth operation. This invention features quantitative filling adjustment, improving convenience and preventing protein leakage after filling, thus avoiding resource waste and environmental pollution.

[0028] like Figure 4As shown, the adjustable mounting assembly 6 includes an adjustable mounting base plate 6-1 that is slidably connected to two lifting slide rods 3-3 via linear bearings and connected to a fine-tuning screw 3-5 via a screw nut. The adjustable mounting base plate 6-1 has a through slot 6-5 through which several filling valve assemblies 7 can pass. It also includes multiple mounting sliders 6-2 mounted on the adjustable mounting base plate 6-1 above the through slot 6-5 for mounting the filling valve assemblies 7. The spacing between two adjacent mounting sliders 6-2 is adjustable. Furthermore, two adjusting vertical plates 6-3 are fixedly connected to the adjustable mounting base plate 6-1, respectively disposed on both sides of the through groove 6-5. One adjusting vertical plate 6-3 has a groove extending along its length, and the other adjusting vertical plate 6-3 has a mounting strip hole 6-4 extending along its length, and the cross-section of the mounting strip hole 6-4 is stepped. A plurality of mounting sliders 6-2 are disposed between the two adjusting vertical plates 6-3 and are slidably connected to them. A through groove for passing through the filling valve assembly 7 is provided at the center of each mounting slider 6-2. Two protrusions are integrally formed on the two opposite sides of each mounting slider 6-2. The two protrusions are slidably inserted into the groove and the mounting strip hole 6-4, respectively. In addition, each mounting slider 6-2 is locked to the adjusting vertical plate 6-3 by bolts and lock nuts inserted in the mounting strip hole 6-4.

[0029] See further Figure 5 The aforementioned filling valve assembly 7 includes a filling valve cylinder structure with a liquid outlet and a rubber ring at the bottom. An inlet 7-7 is connected to the upper part of the filling valve cylinder structure, and the inlet 7-7 is connected to a corresponding reversing valve 5-4. The filling valve assembly 7 also includes a valve stem drive cylinder 7-11 mounted on the upper part of the filling valve cylinder structure, and a cylinder mounting seat 7-10 mounted on the filling valve cylinder structure. The valve stem drive cylinder 7-11 is mounted on the cylinder mounting seat 7-10. Furthermore, a filling valve stem 7-6 is installed at the protruding end of the valve stem drive cylinder 7-11, passing through the filling valve cylinder structure. A sealing head 7-2 for sealing the liquid outlet of the filling valve cylinder structure is installed at the lower end of the filling valve stem 7-6. The assembly also includes venting passages formed in the sealing head 7-2, the filling valve stem 7-6, and the filling valve cylinder structure.

[0030] Furthermore, an air outlet chamber is provided at the upper part of the filling valve cylinder structure, and an exhaust port 7-9 communicating with the air outlet chamber is provided on the outer wall of the filling valve cylinder structure; a longitudinal airflow channel 7-1 is provided at the center of the filling valve stem 7-6, and a radial airflow channel 7-13 communicating with the longitudinal airflow channel 7-1 is provided at the upper part of the filling valve stem 7-6 above the air outlet chamber; in addition, the aforementioned sealing head 7-2 is made of rubber, and a through hole is provided at the center of the sealing head 7-2, and a copper sleeve communicating with the longitudinal airflow channel 7-1 is inserted into the through hole; wherein, the inner cavity of the copper sleeve, the longitudinal airflow channel 7-1, the radial airflow channel 7-13, the air outlet chamber and the exhaust port 7-9 constitute an exhaust passage.

[0031] like Figure 5 As shown, the above-mentioned filling valve cylinder structure includes a filling valve cylinder 7-5 with an inlet 7-7. A flange is provided in the middle of the outer wall of the filling valve cylinder 7-5. The flange is connected to the mounting slider 6-2 in the adjustable mounting assembly 6 by bolts. A filling outlet head 7-4 is installed at the lower open end of the filling valve cylinder 7-5 by bolts. Furthermore, the filling outlet head 7-4 is connected to the filling valve cylinder 7-5 by a flange, and a rubber ring is installed on the bottom surface of the flange of the filling outlet head 7-4. When the filling outlet head 7-4 is inserted into the bottle mouth, the upper end of the bottle mouth is pressed against the rubber ring, thereby preventing liquid from splashing during the filling process. The liquid splashes onto the outside of the bottle opening; the bottom of the inner cavity of the filling head 7-4 is arc-shaped and has an outlet. The sealing head 7-2 can open or block the outlet under the action of the filling valve rod 7-6; an upper venting end 7-8 is screwed into the upper opening of the filling valve cylinder 7-5. The filling valve rod 7-6 passes through the center hole of the upper venting end 7-8 and multiple sealing rings are provided between them. The venting chamber is located at the center of the upper venting end 7-8, and the exhaust port 7-9 is opened on the upper part of the outer wall of the upper venting end 7-8; in addition, an end cap 7-12 for blocking the venting chamber is provided on the upper part of the upper venting end 7-8.

[0032] Furthermore, a guide ring 7-3 is installed at the lower part of the filling valve stem 7-6. The guide ring 7-3 includes a mounting sleeve installed on the filling valve stem 7-6, and several tangential spiral blades are evenly distributed circumferentially on the outer wall of the mounting sleeve. The outer ends of each of the aforementioned tangential spiral blades extend to the inner wall of the cavity of the filling valve cylinder structure, and a guide gap is formed between two adjacent tangential spiral blades. Each tangential spiral blade is spirally inclined from top to bottom in a clockwise or counterclockwise direction, and the spiral inclination direction of all tangential spiral blades is consistent. By setting the guide ring 7-3, the liquid material can be rectified, preventing the liquid material from dispersing or deviating from the center of the outlet of the filling valve cylinder structure, ensuring that the liquid material flows out of the outlet of the filling valve cylinder structure in a columnar shape and downward, thereby effectively improving the filling effect of the liquid material and avoiding contamination of the bottle mouth.

[0033] Working principle:

[0034] In actual operation, the protein solution is stored in the storage tank 10. The stirring motor 8 drives the stirring structure 9 to rotate continuously, thereby stirring the liquid in the storage tank 10 and preventing the protein solution from separating due to long-term static separation.

[0035] During the filling process, multiple packaging bottles are manually placed or transported to the bottom of multiple filling valve assemblies 7 using a linear conveyor. Then, the lifting drive 3-1 is activated to move the adjustable mounting assembly 6 downwards until the lower part of the filling outlet head 7-4 in the filling valve assembly 7 is inserted into the bottle mouth. At the same time, the upper part of the bottle mouth is in tight contact with the rubber ring installed on the filling outlet head 7-4 to prevent liquid from splashing outside the packaging bottle during filling.

[0036] Then, the reversing valves 5-4 in the measuring cylinder assembly 5 are activated, connecting the adjusting measuring cylinder 5-1 to the storage tank 10 via the reversing valves 5-4 and the liquid pipeline, while simultaneously disconnecting the adjusting measuring cylinder 5-1 from the filling valve assembly 7. Next, the lifting adjusting motor 2-1 is activated, driving the lifting screw 2-3 to rotate, which in turn moves the adjusting lifting seat 2-5 downwards by a preset distance, causing the piston 2-7 in the corresponding adjusting measuring cylinder 5-1 to move downwards by a preset distance, thereby achieving quantitative liquid dispensing operation of each adjusting measuring cylinder 5-1 through negative pressure. Then, the reversing valves 5-4 are activated again, disconnecting the adjusting measuring cylinder 5-1 from the storage tank 10, while simultaneously connecting each adjusting measuring cylinder 5-1 to the corresponding filling valve assembly 7. Then, the lifting adjusting motor 2-1 is activated again, driving the lifting screw 2-3 to rotate in the opposite direction, thereby... Each piston 2-7 moves upward a preset distance, pushing the liquid in each adjusting cylinder 5-1 into the filling valve assembly 7. Simultaneously, each valve stem drive cylinder 7-11 is activated, driving the corresponding filling valve stem 7-6 to move upward and open the liquid outlet of the filling valve assembly 7. This allows the protein liquid to enter the inner cavity of the filling valve cylinder structure of the filling valve assembly 7, and then flow downward from the liquid outlet of the filling valve assembly 7 after being rectified by the guide ring 7-3, thus performing the filling operation. During the filling process, the gas in the packaging bottle is discharged to the outside of the filling valve assembly 7 through the exhaust passage formed by the inner cavity of the copper sleeve, the longitudinal airflow channel 7-1, the radial airflow channel 7-13, the gas outlet chamber, and the exhaust port 7-9. After the filling operation is completed, the lifting drive 3-1 is activated again, driving the adjustable mounting assembly 6 and the several filling valve assemblies 7 mounted on it to move upward to the initial position.

[0037] When it is necessary to adjust the quantitative filling of the filling device according to the specifications of the packaging bottle, it is only necessary to adjust the number of rotations of the lifting screw 2-3 to adjust the moving distance of the adjusting lifting seat 2-5, thereby adjusting the liquid volume of each adjusting cylinder 5-1 when quantitative liquid is taken, thus realizing the quantitative adjustment of the filling device. The adjustment process is simple and convenient, the quantitative adjustment is stable, the service life is long, the maintenance cost is low, and it is conducive to improving the filling efficiency.
