Description

Technical Field

[0001] This application relates to the field of food packaging equipment technology, specifically an automatic packaging device for soybean protein powder. Background Technology

[0002] In the modern food processing industry, soy protein powder is widely used in various food production processes as an important nutritional fortifier and functional food ingredient. With the continuous growth in market demand for soy protein powder, the requirements for its packaging efficiency and quality are also increasing.

[0003] Some existing soybean protein powder packaging equipment uses a fixed-height structure for its docking and feeding mechanism. The vertical distance between the lower end of the docking cylinder and the conveying component is a fixed value, which is only suitable for packaging containers of a specific height. When it is necessary to change to packaging barrels of different heights, the machine must be stopped for the complete disassembly of the docking cylinder, the adapter cylinder, and related moving parts, and a complete set of docking components adapted to the height of the new container must be installed. This replacement process involves multiple steps, such as removing positioning bolts, calibrating the coaxiality of components, and calibrating stroke parameters. The operation is complex and time-consuming. Therefore, it is necessary to design an automatic soybean protein powder packaging device to solve the above problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an automatic packaging device for soybean protein powder, which solves the problem that some existing soybean protein powder packaging equipment requires stopping the machine to disassemble and replace the entire docking assembly when changing packaging barrels of different heights due to the fixed height of the docking powder feeding mechanism, which is complicated and time-consuming.

[0006] The technical solution adopted by this application to solve its technical problem is: an automatic packaging device for soybean protein powder, including a support, a feeding cylinder and a conveying assembly. Assembly plates are fixed on both sides of the support, and an assembly frame is fixed on the upper end of the assembly plate. The feeding cylinder is fixed on the assembly frame. The conveying assembly is located below the central axis of the feeding cylinder and is suitable for carrying and conveying packaging containers. A transition cylinder is fixed at the lower end of the feeding cylinder, and a connecting cylinder is provided on the outer sleeve of the transition cylinder.

[0007] The upper end of the feeding cylinder is fixed with a connecting plate. A rotating rod is connected to the connecting plate by a power drive and rotates.

An intermediate rod extending into the adapter cylinder is fixed on the limiting plate. A short rod is fixed at the lower end of the intermediate rod. A spiral blade located in the docking cylinder is fixed on the short rod.

[0008] An electric push rod is mounted on one side of the assembly plate, and a push plate fixed to the docking cylinder is mounted on the output end of the electric push rod.

[0009] Furthermore, multiple retaining strips are fixed in the circumferential direction inside the docking cylinder, and multiple retaining grooves that are adapted to the retaining strips are provided in the circumferential direction of the adapter cylinder.

[0010] Furthermore, a servo motor is mounted on the connecting plate, and the output end of the servo motor is coaxially connected to the upper end of the rotating rod.

[0011] Furthermore, the portion of the rotating rod located inside the feeding cylinder is respectively fixed with a main stirring blade and an auxiliary stirring blade.

[0012] Furthermore, the lower end of the bracket is fixed with multiple support legs.

[0013] Furthermore, a base is fixed inside the docking cylinder, and the lower end of the short rod is rotatably connected to the base.

[0014] Furthermore, the lower end of the docking cylinder is an inverted frustum-shaped structure, with the inner diameter gradually decreasing from top to bottom to form a constricted opening that can dock with the opening of the packaging container.

[0015] The beneficial effects of this application are: The automatic packaging device for soybean protein powder provided by this application pushes the push plate through the electric push rod, thereby causing the docking cylinder to slide up and down on the outer wall of the transfer cylinder, realizing the automatic adjustment of the docking cylinder height. It eliminates the need to stop the machine to disassemble and replace the entire docking assembly, solving the problem of complicated and time-consuming operation when changing packaging barrels of different heights in existing equipment.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0026] like Figures 1-5 As shown, this application provides an automatic packaging device for soybean protein powder, including a support frame 1, an assembly plate 3, a feeding cylinder 5, a transfer cylinder 6, a docking cylinder 7, a rotating rod 12, a limiting plate 16, an intermediate rod 17, a short rod 18, a spiral blade 19, a base 20, an electric push rod 21, a push plate 22, and a conveying assembly 23. The support frame 1 is welded from Q235B carbon structural steel, with four adjustable legs 2 symmetrically arranged at the bottom. Rubber anti-slip pads are fitted to the lower ends of the legs 2, and the height difference can be adjusted within ±50mm via threaded knobs to adapt to different ground flatness environments, ensuring that the overall verticality deviation of the device does not exceed 0.5°. The assembly plates 3 on both sides of the support frame are made of 10mm thick stainless steel plates and are welded and fixed to the support frame 1. An assembly frame 4 is welded to the upper end of the assembly plate 3, and the feeding cylinder 5 is welded and fixed to the assembly frame 4, while ensuring that the verticality tolerance between the central axis of the feeding cylinder 5 and the ground is ≤0.3mm.

[0027] The feeding cylinder 5 is made of food-grade 304 stainless steel with a wall thickness of 5mm. Reinforcing ribs are welded to the outer side of the cylinder to enhance its compressive strength. A connecting plate 10 is welded to the upper end of the feeding cylinder 5, and a servo motor 11 (model: MS1H1-75B30CB-A331Z) is mounted on the connecting plate 10. The output shaft of the servo motor 11 is coaxially connected to the rotating rod 12 via a flexible coupling. The rotating rod 12 is a 30mm diameter stainless steel round bar, and the main stirring blade 13 and auxiliary stirring blade 14 are welded to its portion inside the feeding cylinder 5. Two sets of main stirring blades 13 are symmetrically distributed and designed with a 45° inclination angle. The cooperation of the two sets of stirring blades ensures that the protein powder in the feeding cylinder has a mixing uniformity of ≥95%, effectively preventing clumping.

[0028] The conveyor assembly 23 adopts a belt conveyor structure, consisting of a drive motor (model: Y90S-4), a reducer (model: RV40-100), and a circular conveyor belt. The conveyor belt is made of food-grade PU material, with a width of 300mm, and the conveying speed can be frequency-adjusted within the range of 0.5-2m / min. The conveyor assembly is located directly below the central axis of the feed cylinder 5 and is used to carry and transport packaging containers.

[0029] The adapter cylinder 6 is welded and fixed to the lower end of the feeding cylinder 5. It is made of stainless steel, and multiple axial grooves 9 are machined on the outer side of the cylinder wall to form a sliding fit structure with the retaining strips 8 on the inner side of the docking cylinder 7. The docking cylinder 7 is sleeved on the outside of the adapter cylinder 6. It is also made of stainless steel, and multiple retaining strips 8 are welded on the inner side of the cylinder. The retaining strips 8 have a T-shaped cross-section, and the clearance between them and the grooves 9 is ≤0.5mm, ensuring that the radial runout during sliding is ≤0.8mm. The lower end of the docking cylinder is machined into an inverted frustum-shaped constricted structure with a taper of 15°. The minimum inner diameter of the constriction is designed according to the diameter of common packaging containers. The up and down stroke can be adjusted by driving the push plate 22 through the electric push rod 21 (model: DT50-100).

[0030] The servo motor 11 on the connecting plate 10 is controlled by a PLC (model: S7-200SMART) to start, stop, and adjust its speed, with a speed adjustment range of 0-1500 r / min. An axial limiting groove 15 is formed at the lower end of the rotating rod 12, and a limiting plate 16 is slidably connected to the limiting groove 15 with a clearance ≤0.3mm. The limiting plate 16 is connected to the short rod 18 via an intermediate rod 17, and the lower end of the short rod 18 is rotatably connected to the base 20, which is fixed to the bottom of the inner wall of the docking cylinder 7.

[0031] The spiral blade 19 is welded and fixed to the outside of the short rod 18. It is made of 2mm thick stainless steel plate. The lower end of the blade is 50mm away from the upper edge of the constriction of the docking cylinder 7. When the docking cylinder 7 moves up and down, the spiral blade 19 will move synchronously with the docking cylinder 7. The upper end of the spiral blade 19 can extend into the adapter cylinder 6 to ensure no movement interference. The electric push rod 21 is welded and fixed to the outside of the docking cylinder 7 through the push plate 22. The push plate 22 is made of 10mm thick stainless steel plate and is connected to the electric push rod 21 by M8 bolts. The connection part is provided with reinforcing ribs to ensure that the parallelism deviation of the docking cylinder 7 is ≤0.3mm when the push plate 22 is driven.

[0032] Working principle: When packaging soybean protein powder, the packaging container is first placed on the conveying component 23. The conveying component 23 transports the packaging container to the lower part of the central axis of the feeding cylinder 5. Then, according to the height of the packaging container, the electric push rod 21 is started by the external power supply and the corresponding control button. The output end of the electric push rod 21 pushes the push plate 22. The push plate 22 drives the docking cylinder 7 to slide down on the adapter cylinder 6, so that the lower end of the docking cylinder 7 is connected with the opening of the packaging container. During the docking process, the clamping strip 8 slides in the clamping groove 9 to ensure the stability and accuracy of the sliding of the docking cylinder 7.

[0033] Next, the servo motor 11 is started by connecting an external power supply and the corresponding control button. The servo motor 11 drives the rotating rod 12 to rotate. The rotating rod 12 drives the main stirring blade 13 and the auxiliary stirring blade 14 to stir the soybean protein powder in the feeding cylinder 5, preventing it from clumping and ensuring the flowability of the soybean protein powder. At the same time, the limiting plate 16 in the limiting groove 15 at the lower end of the rotating rod 12 rotates together with the rotating rod 12. The limiting plate 16 drives the short rod 18 and the spiral blade 19 to rotate through the middle rod 17. The spiral blade 19 evenly transports the soybean protein powder in the feeding cylinder 5 into the packaging container through the transfer cylinder 6 and the docking cylinder 7.

[0034] When the soybean protein powder filling in the packaging container is completed, the servo motor 11 stops rotating, and the electric push rod 21 drives the docking cylinder 7 to slide upward and detach from the packaging container. This does not affect the movement of the packaging container on the conveying component 23. At this time, during the upward movement of the spiral blade 19, some blades will enter the transfer cylinder 6. At the same time, the inner diameter of the transfer cylinder 6 is larger than the circumference diameter of the spiral blade 19, so there will be no motion interference problem. Then, the conveying component 23 will transport the packaged container out to complete one packaging process.

[0035] When it is necessary to change packaging containers of different heights, simply control the extension and retraction of the electric push rod 21 and adjust the height of the docking cylinder 7 to align it with the opening of the new packaging container. There is no need to stop the machine to disassemble and replace the entire docking assembly, which greatly improves production efficiency.

[0036] Throughout the entire operation, the limiting groove 15 and the limiting plate 16 ensure that the intermediate rod 17, the short rod 18 and the spiral blade 19 can rotate together with the rotating rod 12 while sliding up and down with the docking cylinder 7. This ensures that the feeding function is not affected by the height adjustment, guarantees the stability of the feeding process, and prevents problems such as material blockage and uneven feeding. The base 20 provides support for the short rod 18, ensuring the stability of the rotation of the spiral blade 19.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
