Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a feeding component of a plant protein mixing device. Background Technology

[0002] Currently, plant protein, due to its natural source, complete nutritional structure, and easy digestibility and absorption, is gradually replacing animal protein and is widely used in functional foods, nutritional products, and health drinks. As the industrial processing level of plant protein continues to improve, quality control during the mixing process becomes particularly crucial, especially in the material pretreatment stage, where the precision of powder addition and the uniformity of mixing directly affect the stability and taste of the product. Faced with increasingly stringent market demands for quality control standards, the structural design of related equipment also needs continuous optimization to adapt to the process requirements of materials with different proportions and properties.

[0003] Regarding the aforementioned issues, most plant protein mixing devices on the market typically consist of a separately configured hopper and feeding channel. Raw materials generally enter the mixing chamber by gravity. These devices often use simple flap or valve structures to control material flow, with some systems supplemented by time relays for coarse timing, opening or closing the hopper outlet, relying on the material's own flowability to transport it into the mixing tank. The mixing section usually features a single mixing shaft driven by a motor, rotating a set of mixing blades. The feeding action and mixing process operate independently, and continuous dynamic feeding control cannot be achieved during mixing. While these devices are structurally simple and intuitive, facilitating manufacturing and maintenance, they often fail to meet the process requirements of precise feeding and efficient mixing simultaneously in actual production.

[0004] A common problem with existing technologies is the low precision in controlling the feeding process. The feeding amount largely relies on time settings or manual estimation, making it prone to overfeeding or underfeeding, resulting in significant fluctuations in material ratios and affecting product stability. The connection structure between the hopper and the feeding port is crudely designed, lacking controllable nodes in the feeding path and failing to achieve effective flow control, leading to uneven material descent or momentary blockages. Long-term accumulation of powder in the hopper easily causes agglomeration, often requiring external force to clear it during feeding, making operation cumbersome. Regarding the mixing structure, traditional single-axis unidirectional rotation is insufficient for quickly breaking up agglomerated powders, resulting in numerous mixing dead zones, especially inefficient and time-consuming processes involving high-viscosity plant protein systems. Furthermore, traditional mixers fail to consider the mutual interference between mixing directions, causing uneven shear force distribution and affecting the final mixing quality.

[0005] To address the above problems, a feeding component for a plant protein mixing device is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a feeding component for a plant protein mixing device, aiming to solve the problems of inaccurate feeding, uncontrollable material falling, and low mixing efficiency in existing plant protein mixing devices.

[0010] As a further description of the above technical solution:

[0011] The inner cylinder is slidably connected to the inside of the outer cylinder. The left side of the inner cylinder is hollow, and the bottom of the injection pipe is installed inside the mixing tank.

The stirring assembly is provided inside the outer protective cover. The stirring assembly includes a main bevel gear, an upper bevel gear, and a lower bevel gear. An inner shaft is fixedly connected inside the upper bevel gear, and an outer shaft is fixedly connected inside the lower bevel gear.

[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 2This utility model provides an embodiment of a feeding component for a plant protein mixing device, comprising a base plate 1, a mixing tank 2 disposed on one side of the top of the base plate 1 for containing and mixing powdered materials such as plant protein powder, an inlet 4 disposed on one side of the top of the mixing tank 2 for initial introduction of external materials, and a mixing mechanism 6 disposed at the center of the top of the mixing tank 2. This mechanism can achieve coaxial and counter-rotating of multiple mixing blades 636 through an internal bevel gear transmission structure, thereby improving the mixing efficiency and uniformity of the powder in the tank. Two spaced-apart support blocks 3 are disposed on the other side of the top of the base plate 1, and a quantitative feeding mechanism 5 is installed between the two support blocks 3. The quantitative feeding mechanism 5 mainly includes an electric push rod 501 fixed to the top of one of the support blocks 3 and a connecting rod 507 disposed at its output end. The end of the connecting rod 507 away from the electric push rod 501 is connected to a feeding component. The core of the feeding component is an inner cylinder 504. The left side of the inner cylinder 504 is a cavity structure with an axially penetrating inner through hole 505 for guiding the material conveying flow. A control component is provided on the outside of the inner cylinder 504 to adjust the feeding path and flow rate. This control component includes an outer cylinder 503 fixedly installed on the top of the support block 3, and the inner cylinder 504 is slidably installed inside the outer cylinder 503, allowing it to move left and right under the drive of the electric push rod 501, thereby controlling the time and quantity of material entering the inner cylinder 504 from the hopper 502. Two slots not on the same vertical line are opened on both sides of the side wall of the outer cylinder 503. The upper slot is used to fix the bottom of the hopper 502, so that the plant protein powder pre-filled in the hopper 502 can flow into the inner cylinder 504 when it moves to the corresponding position. The lower slot is connected to the injection pipe 506, the bottom of which extends into the interior of the mixing tank 2, so that the material is injected into the mixing tank 2 by the feeding component in a timed and quantitative manner.

[0033] Reference Figure 3 - Figure 4The mixing mechanism 6 includes an outer protective cover 61 and a drive motor 62 located on the top of the mixing tank 2. The outer protective cover 61 provides external protection for the mixing assembly 63, preventing material splashing or foreign objects from entering during the mixing process, ensuring the safety and stability of the mixing process. The output end of the drive motor 62 passes through the outer protective cover 61 and is fixedly connected to the center of the main bevel gear 631, enabling it to drive the main bevel gear 631 to rotate after being energized. The main bevel gear 631 is vertically positioned between the upper bevel gear 632 and the lower bevel gear 633, forming a meshing transmission structure with both. The main bevel gear 631 drives the two sets of bevel gears to transmit power in both vertical and horizontal directions. The upper bevel gear 632 is positioned directly above the lower bevel gear 633, and the two gears rotate relative to each other around the main bevel gear 631 through mutual meshing. To ensure the stability and structural strength of the mechanism, a support frame 637 is provided around the three sets of bevel gears for rigid support, preventing offset or shaking under high-speed operation. An inner shaft 635 is fixedly installed inside the upper bevel gear 632. This inner shaft 635 passes vertically through the outer shaft 634 and can rotate independently. An outer shaft 634 is fixedly connected inside the lower bevel gear 633. The outer shaft 634 is located inside the top wall of the mixing tank 2 and is rotatably connected to the top wall of the mixing tank 2 via bearings or a sliding fit. Simultaneously, the inner shaft 635 is coaxially arranged in its internal cavity. The inner shaft 635 achieves relative rotational engagement with the outer shaft 634 via bearings, allowing both to rotate independently around the same axis. Multiple stirring blades 636 are evenly fixedly installed on the outer sides of both the outer shaft 634 and the inner shaft 635. Each group of stirring blades 636 is radially distributed. The dual-shaft structure design enables the blades to rotate in opposite directions on the same axis, thereby creating a strong convection stirring effect inside the mixing tank 2, greatly enhancing the dispersion speed and mixing uniformity of powdered materials in the liquid. The mixing mechanism 6 combines bevel gear transmission, dual-shaft reversal, and multi-blade design, which not only improves mixing efficiency but also effectively prevents material sedimentation or agglomeration, thereby enhancing the overall performance and adaptability of the mixing system.

[0034] Working principle: Plant protein powder is pre-added to hopper 502. After starting the electric push rod 501, its output end drives the connecting rod 507 to move. The connecting rod 507 drives the inner cylinder 504, which is slidably connected to the outer cylinder 503, to slide. When the inner through hole 505 of the inner cylinder 504 is aligned with the upper slot of the outer cylinder 503, the material in hopper 502 enters the inner cylinder 504 under the action of gravity. The electric push rod 501 pulls back the connecting rod 507, causing the inner cylinder 504 to slide. When the inner through hole 505 is aligned with the bottom slot of the outer cylinder 503, the material enters the interior of the mixing tank 2 from the inner cylinder 504 through the feeding pipe 506. At the same time, the mixing mechanism 6 is started, and the drive motor 62 drives the main bevel gear 631 to rotate. The inner shaft 635 and outer shaft 634 are driven to rotate by the upper bevel gear 632 and lower bevel gear 633 meshing with it, respectively. The upper bevel gear 632 is located directly above the lower bevel gear 633, and the main bevel gear 631 is vertically arranged between them, forming a vertical transmission structure. The outer shaft 634 is rotatably connected to the inside of the top wall of the mixing tank 2, and the inner shaft 635 is coaxially arranged inside the outer shaft 634 and rotatably connected to its inner wall, forming a double-shaft structure. As the main bevel gear 631 rotates, the inner shaft 635 and the outer shaft 634 rotate in opposite directions on the same axis, driving the stirring blades 636 installed on its outer side to run synchronously, thereby realizing high-speed, bidirectional powder-liquid mixing in the mixing tank 2.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
