Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of mixing machine technology, and more specifically, to a compressed biscuit mixing machine. Background Technology

[0002] With the continuous development of the food industry, compressed biscuits are in high demand in fields such as emergency food and outdoor food due to their high energy density, easy storage and portability. The mixing process is one of the key steps that determines the quality of compressed biscuits.

[0003] Early mixing machines mostly used simple mixing structures, relying on mechanical mixing force to mix various raw materials. With the advancement of technology, various types of mixing machines have appeared on the market, such as double-helix cone mixing machines and planetary mixing machines. Although these devices have improved mixing efficiency and uniformity to a certain extent, with the continuous improvement of the quality requirements for compressed biscuits, existing mixing machines have gradually revealed some problems in practical applications.

[0004] A prominent problem currently facing compressed biscuit mixing machines is the poor mixing effect. This poor mixing effect is mainly reflected in the uneven mixing of raw materials between different levels. This is because the raw materials are diverse and have different properties, including ingredients such as flour, oil, sugar, and additives. Some ingredients are relatively loose, while others are more viscous, or they are granular or liquid. Existing mixing machines usually have their mixing structure arranged on horizontal levels, and the stirring is achieved by a rotating shaft. However, this cannot fully mix the various ingredients between different levels, making it difficult to achieve uniform dispersion of materials between different levels during the mixing process. This affects the consistency of the taste and quality of the compressed biscuits. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a compressed biscuit mixing machine, which solves the technical problem in the related art that the mixing paddles of the mixing machine are usually arranged in various ways along the horizontal layers, making it difficult to achieve uniform dispersion of raw materials between the upper and lower layers.

[0006] According to one aspect, at least one embodiment of this disclosure provides a compressed biscuit mixing machine, comprising:

[0007] frame;

[0008] A material cylinder is mounted on the frame, and the inner wall of the material cylinder has an annular toothed portion;

[0009] A rotating shaft is rotatably mounted on the frame and located inside the material cylinder;

[0010] The stirring paddle rotates relative to the rotating shaft and has a stirring branch. One end of the stirring paddle has a gear part that meshes with the annular tooth part. The rotation axis of the stirring paddle intersects the axis of the rotating shaft. The stirring paddle is configured such that, after rotation, it drives the stirring branch to stir the upper and lower layers of raw materials in the material cylinder.

[0011] For example, in a compressed biscuit mixing machine provided in at least one embodiment of this disclosure, the inner wall of the material cylinder also has an annular groove, the bottom wall of the annular groove has the annular toothed portion, the gear portion is located in the annular groove and meshes with the annular toothed portion.

[0012] For example, in a compressed biscuit mixing machine provided in at least one embodiment of this disclosure, an anti-blocking block is sleeved on one end of the mixing paddle near the gear part, and the anti-blocking block slides in the annular groove. The anti-blocking block has a shoveling inclined surface, which is configured to slide along the annular groove under the drive of the rotating shaft, so that the shoveling inclined surface scoops out the raw material in the annular groove.

[0013] For example, in a compressed biscuit mixing machine provided in at least one embodiment of this disclosure, a sealing ring is sleeved on one end of the mixing paddle near the gear part, and the sealing ring slides in the ring groove. The sealing ring is used to seal the gear part in the ring groove and prevent the raw material from entering the ring groove.

[0014] For example, in a compressed biscuit mixing machine provided in at least one embodiment of this disclosure, there are two mixing blades, which are symmetrically arranged, and the mixing branch is arc-shaped with an arc of less than π / 2. An avoidance gap is formed between the ends of the mixing branches of the two mixing blades, and the avoidance gap allows the rotating shaft to pass through.

[0015] For example, in a compressed biscuit mixing machine provided in at least one embodiment of this disclosure, the mixing branch is in two sets, the mixing paddle is rod-shaped, and each side of the mixing paddle has a set of the mixing branch, each set of the mixing branch including a plurality of the mixing branch arranged at intervals along the length direction of the mixing paddle.

[0016] For example, in a compressed biscuit mixing machine provided in at least one embodiment of this disclosure, a mounting block is slidably connected to the side wall of the rotating shaft radially along the rotating shaft, and the mounting block is rotatably and slidably connected to the stirring paddle. The compressed biscuit mixing machine further includes:

[0017] An elastic element, one end of which acts on the rotating shaft and the other end of which acts on the mounting block, is used to elastically push the mounting block so that the mounting block presses against the stirring paddle.

[0018] For example, in a compressed biscuit mixing machine provided in at least one embodiment of this disclosure, the mounting block has a handle on its side wall. The handle is configured to move the mounting block closer to the rotating shaft when subjected to external force, so as to separate the mounting block from the mixing paddle.

[0019] For example, in a compressed biscuit mixing machine provided in at least one embodiment of this disclosure, the material cylinder is rotatably mounted on the frame, the rotation axis of the material cylinder is collinear with the axis of the rotating shaft, and a limit ring is raised and lowered on the frame. The limit ring is sleeved on the material cylinder and abuts against the outer wall of the material cylinder.

[0020] For example, in a compressed biscuit mixing machine provided in at least one embodiment of this disclosure, the top and bottom of the rotating shaft are provided with blades, and the mixing paddle is located between the two blades.

[0021] The beneficial effects of the embodiments disclosed herein are as follows:

[0022] 1. Uniform Mixing: Compressed biscuit ingredients are diverse, including loose flour, viscous oils, and granular or liquid components. Traditional mixers have horizontally arranged mixing sections, relying on a rotating shaft for agitation, making it difficult to fully mix the various ingredients between different levels. This mixer, however, features a mixing paddle whose rotation axis intersects with the shaft's axis, and a gear at one end of the paddle meshes with the annular teeth on the inner wall of the cylinder. As the shaft rotates, the paddle revolves around the shaft while simultaneously rotating due to the meshing of the gear and annular teeth. This effectively agitates the ingredients in the upper and lower layers of the cylinder, achieving thorough mixing between each level and greatly improving the uniformity of the mixture.

[0023] 2. Adaptable to diverse raw material properties: Traditional mixing machines struggle to handle raw materials with varying properties. However, the combined revolution and rotation of the mixing paddle allows the mixing branches to penetrate deep into all parts of the mixing drum, ensuring thorough mixing of materials with different properties. Whether it's loose flour, viscous oil, or granular or liquid components, the mixing paddle achieves uniform mixing, significantly improving its adaptability to diverse raw material properties.

[0037] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0038] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

Therefore, they should not be construed as limitations on this disclosure.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] like Figure 1As shown, it illustrates a compressed biscuit mixing machine according to an embodiment of the present disclosure. The working process of the mixing machine is as follows: when the power is turned on, the drive device (motor) drives the vertically arranged rotating shaft 3 to start rotating on the frame 1. The rotating shaft 3 is located inside the material cylinder 2, its bottom is rotatably connected to the bottom wall of the material cylinder 2, and its top is connected to the motor. The rotating shaft 3 provides basic power for the entire mixing process. As the rotating shaft 3 rotates, the gear part 402 at one end of the stirring paddle 4 interacts with the annular tooth part 201 on the inner wall of the material cylinder 2. Since the gear part 402 meshes with the annular tooth part 201 and is rotatably connected to the rotating shaft 3, the stirring paddle 4 starts to rotate (rotate) while revolving around the rotating shaft 3. The rotation axis of the stirring paddle 4 intersects with the axis of the rotating shaft 3, thereby enabling the stirring branch 401 on the stirring paddle 4 to perform complex and efficient stirring actions between the upper and lower layers in the barrel 2. Whether it is the relatively loose flour in the upper layer, the relatively viscous oil in the lower layer, or granular or liquid components, they are all fully turned over and mixed under the action of the stirring branch 401, realizing the uniform dispersion of raw materials between the upper and lower layers.

[0044] Traditional mixing machines typically have their mixing branches 401 arranged horizontally, relying solely on the rotating shaft 3 for simple stirring. However, the mixing branches 401 of the mixing paddle 4 in this mixing machine combine revolution and rotation to stir the raw materials vertically, greatly improving the uniformity of mixing and thus ensuring the consistency of the taste and quality of the compressed biscuits.

[0045] Specifically, the stirring paddle 4 rotates relative to the rotating shaft 3, and a gear part 402 is provided at the end away from the rotating shaft 3. The stirring paddle 4 has an integrally formed or detachably connected stirring branch 401 by bolts. The shape and distribution of the stirring branch 401 can be linear or circumferential, and the shape can be straight, arc or frame-shaped, which can efficiently stir the raw materials during rotation.

[0046] In addition, the material cylinder 2 is usually designed in a cylindrical shape. The material of the material cylinder 2 is generally stainless steel, which ensures both strength and good hygiene performance. The top is equipped with a feed port for easy input of various raw materials, and the bottom is equipped with a discharge port for easy discharge of mixed materials. The frame 1 is welded from sturdy steel, which has sufficient strength and stability to withstand the weight of the raw materials in the material cylinder 2 and the various forces generated during the mixing process.

[0047] like Figure 2As shown, in some examples, the annular groove 202 provides a precise positioning space for the meshing of the gear part 402 and the annular tooth part 201, reducing the interference of radial and axial forces on the meshing of the gear part 402 and the annular tooth part 201 during the stirring process, which leads to unstable meshing; at the same time, it optimizes the spatial layout to a certain extent, embedding the meshing structure of the gear part 402 and the annular tooth part 201 in the annular groove 202, rather than protruding from the inner wall of the barrel 2, providing a larger stirring space for the stirring paddle 4, raw materials, etc.

[0048] like Figures 3-4 As shown, in some examples, due to the variety of raw materials, some highly viscous raw materials, such as syrup and oil, may accumulate in the annular groove 202 after being mixed with flour. In order to avoid the raw materials from clogging in the annular groove 202, which would hinder the revolution and rotation of the stirring paddle 4 and affect the stirring effect, an anti-clogging block 5 is fitted on the end of the stirring paddle 4 near the gear part 402 so that the scooping inclined surface 501 of the anti-clogging block 5 acts in the annular groove 202.

[0049] In specific operation, when the rotating shaft 3 drives the stirring paddle 4 to move, the anti-blocking block 5 is sleeved and connected to the stirring paddle 4, so the anti-blocking block 5 also slides in the annular groove 202. As a result, the shovel inclined surface 501 will always contact and shovel up the raw material accumulated on the bottom wall and the wall of the annular groove 202, generating a radial thrust on the raw material along the annular groove 202, shoveling it away from the annular groove 202, and continuing to mix.

[0050] Specifically, the shovel inclined surface 501 can be a plane of 30°-60° or a spiral curved surface to control the direction in which the shoveled material leaves the annular groove 202, so that it moves radially inward or upward and downward; in addition, the anti-blocking block 5 still needs to be opened in advance to avoid the annular toothed part 201, so as to avoid the two from interfering with each other, while playing the role of shoveling material.

[0051] The anti-blocking block 5 can be block-shaped, either cuboid or cube. The through hole in the center is just enough for the stirring paddle 4 to pass through, so as to realize the rotational connection of the sleeve. In addition, shovel inclined surfaces 501 can be symmetrically arranged on both sides of it. On the one hand, it can shovel material regardless of whether the rotating shaft 3 rotates forward or backward. On the other hand, the symmetrical shovel inclined surfaces 501 can also protect the gear part 402 in the annular groove 202 to avoid contact with the raw material and affect the operation.

[0052] like Figures 5-7As shown, in some examples, due to the variety of raw materials, some highly viscous raw materials, such as syrup and oil, may accumulate in the annular groove 202 after being mixed with flour. In order to avoid the raw materials from clogging in the annular groove 202, which would hinder the revolution and rotation of the stirring paddle 4 and affect the stirring effect, an anti-clogging ring is fitted on the end of the stirring paddle 4 near the gear part 402. This completely seals the space in the annular groove 202 except for the gear part 402, preventing the raw materials from entering the annular groove 202, and separately avoiding the meshing position of the gear part 402 so that it can always mesh.

[0053] Specifically, the sealing ring 6 is not a complete annular ring that fits the annular groove 202, but rather has a gap left on the basis of the annular ring that fits the annular groove 202 to accommodate the gear part 402, such as... Figure 7 As shown, when the rotating shaft 3 drives the stirring paddle 4 to move, since the anti-clogging ring is sleeved and connected to the stirring paddle 4, the anti-clogging ring also slides in the ring groove 202, which will not affect the meshing relationship between the gear part 402 and the ring tooth part 201 in the gap. At the same time, the sleeved and connected rotational connection will not affect the rotation or revolution of the stirring paddle 4.

[0054] like Figure 8 As shown, in some examples, two symmetrically arranged stirring paddles 4 are used to simultaneously stir the raw materials in the barrel 2 from different directions to enhance the uniformity of stirring. Since the barrel 2 is cylindrical, in order to ensure that the stirring branch 401 can better act on the upper and lower layers of raw materials in the entire cylindrical space, the stirring branch 401 is designed to be arc-shaped. However, in order to avoid the two symmetrical stirring branches 401 interfering with the vertical axis of rotation 3 during their rotation and revolution, thus blocking their rotation, the arc of the stirring branch 401 is designed to be less than π / 2. A clearance gap 10 is formed between the ends of the stirring branches 401 of the two stirring paddles 4, which allows the axis of rotation 3 to pass through.

[0055] Additionally, a set of stirring branches 401 is provided on each of its two sides to further improve stirring efficiency. Specifically, the two sets of stirring branches 401 on the same stirring paddle 4 can be arranged in a staggered manner along the length of the stirring paddle 4, such as... Figure 8 As shown, this is to cover a larger area of ​​the cylindrical stirring space.

[0056] like Figures 9-10 As shown, in some examples, during the long-term operation of the compressed biscuit mixing machine, the mixing paddle 4, as a component that directly contacts the raw materials and performs the mixing action, is prone to wear or damage due to the characteristics of the raw materials, or faces the need for regular maintenance and cleaning. In such cases, it is necessary to quickly remove the mixing paddle 4 that is rotatably connected to the rotating shaft 3, thereby reducing downtime caused by equipment maintenance.

[0057] The specific loading and unloading process is as follows: First, push the mounting block 7 radially towards the center of the rotating shaft 3 to compress the elastic element 8. At the same time, align the mounting end of the agitator 4 with the mounting block 7 so that the agitator 4 can be smoothly fitted onto the mounting block 7. Then, release the pushing force on the mounting block 7, and the mounting block 7 will press against the agitator 4 under the action of the elastic element 8. This will cause the gear part 402 to automatically mesh with the ring tooth part 201, thus completing the installation operation. The agitator 4 can then rotate normally around the sun and rotate on its own axis. The disassembly process is the opposite. First, support the agitator 4, and apply external force to the mounting block 7 towards the center of the rotating shaft 3 through the handle part 701 to compress the elastic element 8. This will cause the mounting block 7 to move towards the rotating shaft 3, thus separating the mounting block 7 from the agitator 4. The supported agitator 4 can then be removed manually, and the connection between the gear part 402 and the ring tooth part 201 can be disconnected, thus completing the disassembly operation.

[0058] Specifically, the mounting block 7 slides within a radial groove on the side wall of the rotating shaft 3, and the elastic element 8 is arranged in the groove, with its two ends acting on the rotating shaft 3 and the mounting block 7 respectively. Its outer diameter is consistent with the diameter of the groove. The handle 701 is integrally formed with the side wall of the mounting block 7, and its cylindrical shape facilitates the operator's grip and application of force.

[0059] like Figure 11 As shown, in some examples, the barrel 2 rotates and is collinear with the axis of the rotating shaft 3. This allows more raw materials to be processed per unit time. Compared to stirring only by the agitator 4, the rotation of the barrel 2 increases the flow path and mixing opportunities of the raw materials, and also speeds up the mixing speed. In the mass production of compressed biscuits, this helps to shorten the mixing time and improve the overall production efficiency of the mixer. At the same time, when cleaning the residual raw materials inside the barrel 2, the cleaning water can remove the residual raw materials more quickly. The limiting ring 9 is fitted and abuts against the outer wall of the barrel 2, which can ensure the stability of the barrel 2 during rotation. Its lifting and lowering using a screw can adapt to adjust the height to the most suitable and stable position of the barrel 2.

[0060] like Figure 8 As shown, in some examples, the blades 301 located on the upper and lower sides of the stirring paddle 4 work together with the stirring paddle 4 to create a complex raw material mixing flow field inside the barrel 2. The stirring paddle 4 is mainly responsible for stirring the raw materials in the middle of the barrel 2 and mixing them between different levels, while the top and bottom blades 301 perform horizontal stirring at the upper and lower extreme positions. This multi-directional and multi-level stirring action causes the raw materials to form flow trajectories in different directions inside the barrel 2, increasing the contact opportunities between raw materials and ensuring the stability of product taste and quality. Specifically, the blades 301 are straight plates, and the upper and lower blades 301 are perpendicular to each other.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
