Description

Technical Field

[0001] This utility model relates to the field of dough mixer technology, specifically a head-up removable bucket dough mixer. Background Technology

[0002] In existing technology, head-up dough mixers, as basic equipment in the food processing field, are widely used in the dough mixing and stirring processes of pasta, pastries, and other products. This type of equipment typically consists of basic components such as a machine body, upper frame, lower frame, material container, stirring device, and protective structure, which, along with a transmission device, drive the rotation of the stirring shaft and material container. Its structure generally includes power input, motion transmission, and material container loading and unloading fixing devices. A rotation or lifting mechanism between the upper and lower frames enables the opening and closing of the upper components for equipment maintenance or material container replacement. To achieve the head-up movement, existing equipment often uses mechanical linkages, hinges, and auxiliary support components to complete the mechanism's movement. Simultaneously, simple positioning and locking measures are incorporated into the material container installation and disassembly, and stirring shaft linkage processes to ensure the basic functionality of the equipment.

[0003] Existing head-lift dough mixers are widely used in food processing, such as pastries and bread. Structurally, they typically include upper and lower frames, a material container, a mixing device, and a power mechanism driven by chains or gears. The upper frame is connected to the lower frame via hinges and is equipped with a pneumatic rod to achieve the head-lifting action. However, traditional equipment has significant drawbacks in practical use: First, the upper and lower transmission structures are completely separated during the head-lifting process. When the upper frame needs to be closed again during operation, the upper and lower transmission systems must be precisely aligned; otherwise, proper locking cannot be achieved, increasing operational difficulty and risk. Second, the material container is usually secured using a ball-end plunger structure, which is prone to loosening or detachment under heavy force, failing to achieve a secure lock and posing a safety hazard. Third, the power system often uses ordinary motors with chain drives, resulting in high noise, low efficiency, and poor speed adjustment capabilities, failing to meet the demands of modern food processing for intelligent, quiet, and highly efficient collaborative operation.

[0017] 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.

[0018] Please see Figures 1 to 5 This utility model provides a technical solution: a head-up detachable bucket dough mixer, comprising: a lower frame 1, an upper frame 2, a locking disc 3, locking screws 5, an elastic sheet 6, a material bucket 7, and a drive mechanism. The top of the lower frame 1 is provided with a protruding section; one side edge of the upper frame 2 is rotatably disposed on the edge of the protruding section; the locking disc 3 is rotatably disposed on the lower frame 1 and extends to the top surface of the lower frame 1, and the locking disc 3 is provided with a plurality of limiting holes 4 circumferentially; the ends of a plurality of locking screws 5 are fixedly disposed at the bottom end of the locking disc 3; one end of the elastic sheet 6 is fixedly connected to the locking disc 3, and the other end is screwed to the elastic sheet 6; the material bucket 7 is engaged with a plurality of limiting holes 4 by a plurality of bolts; the drive mechanism passes through the protruding section and is respectively disposed inside the upper frame 2 and the lower frame 1.

[0019] It should be noted that during operation, the lower frame 1 serves as the basic support component of the entire structure. Its protruding section at the top provides a fulcrum for the rotation of the upper frame 2. One edge of the upper frame 2 is rotatably positioned at the edge of the protruding section, enabling the upper frame 2 to be raised or lowered. Several locking screws 5 are fixed to the bottom of the locking disc 3 for locking and securing it to the material container 7. The material container 7 is secured by several bolts inserted into the limiting holes 4 on the locking disc 3, ensuring that the material container 7 is stably installed on the lower frame 1 during operation. The elastic deformation of the elastic sheet 6 enables elastic pressing and disassembly of the locking disc 3, thereby enhancing the locking effect. Driven by the drive mechanism, the structure can be automatically rotated, raised, or lowered. Through the synergistic effect of the above components, the material barrel 7 can be easily installed and disassembled, thereby improving the practicality and convenience of the equipment. The upper frame 2 is also equipped with a protective net at its end. When the upper frame 2 is in a horizontal state, the protective net is fastened above the material barrel to prevent the operator from accidentally touching it. A stop bar is also coaxial with the stirring shaft 10. The stop bar is used to enhance the stirring capacity.

[0020] In some examples, the limiting holes 4 are further configured as insertion sections and limiting sections. During operation, the insertion section guides the bolts on the material bucket 7 to be smoothly inserted into the limiting holes 4. After the bolts enter through the insertion section, the material bucket 7 begins to rotate, causing the bolts at the bottom of the material bucket to rotate to the limiting section. At this time, the limiting section limits and positions the bolts, which can effectively improve the installation efficiency of the material bucket 7 and realize the rapid loading and unloading of the material bucket 7 in the dough mixer.

[0021] In some examples, the elastic plate 6 further deforms elastically after the locking screw 5 is tightened and adheres tightly to the bolt at the bottom of the material container 7, thus locking the material container 7. During operation, when the material container 7 needs to be fixed, the locking screw 5 is rotated. When the locking screw 5 is tightened, the elastic plate 6 deforms elastically under the action of the locking screw 5. The deformed elastic plate 6 adheres tightly to the bolt at the bottom of the material container 7, thereby achieving a secure lock on the material container 7 through the continuous pressure of the elastic plate 6 on the bolt. The elastic properties of the elastic plate 6 ensure a tight fit and holding of the bolt, preventing the material container 7 from loosening during operation and improving the reliability and safety of the locking mechanism.

[0022] In some examples, the drive mechanism further includes: a drive component 8, a cylinder 9, a stirring shaft 10, and a linkage assembly. The drive component 8 is fixedly connected to the upper frame 2, and the drive end extends into the interior of the upper frame 2. The cylinder 9 passes through the protruding section, and its two ends are rotatably connected to the upper frame 2 and the lower frame 1. The stirring shaft 10 is rotatably connected to the upper frame 2 and can move synchronously with the upper frame 2 when the upper frame 2 rotates. The stirring shaft 10 and the drive component 8 are connected by a belt and pulley. The linkage assembly is disposed on the stirring shaft 10 and extends through the protruding section into the interior of the lower frame 1.

[0023] It should be noted that during operation, the drive component 8 is fixedly connected to the upper frame 2, with its drive end extending into the upper frame 2 to provide power output to the stirring shaft 10. The cylinder 9 passes through the protruding section, with its two ends rotatably connected to the upper frame 2 and the lower frame 1 respectively. The extension and retraction of the cylinder 9 drives the upper frame 2 to rotate or reset. The stirring shaft 10 moves synchronously with the upper frame 2 during its rotation. Power is transmitted between the stirring shaft 10 and the drive component 8 via a belt and pulley, thus driving the rotation of the stirring shaft 10. The linkage assembly achieves synchronous linkage between the upper frame 2 and the lower frame 1, ensuring that the stirring shaft 10 drives the material container 7 while it is stirring it, thereby increasing the stirring efficiency and enabling the dough mixer to tilt, reset, and stir efficiently.

[0024] In some examples, the linkage components further include: an upper rotating member 11, a lower rotating member 12, a plug rod 13, and a sleeve 14. The upper rotating member 11 is rotatably installed inside the upper frame 2, and the lower rotating member 12 is rotatably installed inside the lower frame 1. The upper rotating member 11 is connected to the top end of the stirring shaft 10 via a belt pulley, and the lower rotating member 12 is connected to the bottom end of the locking disc 3 via a belt pulley. The plug rod 13 is located at the bottom of the upper rotating member 11 via a universal joint and is situated between the protruding sections. One end of the sleeve 14 is installed at the top end of the lower rotating member 12 via a universal joint and is situated inside the protruding section.

[0025] It should be noted that during operation, when the drive component 8 rotates, it drives the stirring shaft 10 to rotate. Since the upper rotating component 11 is connected to the top of the stirring shaft 10 via a belt and pulley, it can drive the upper rotating component 11 to rotate synchronously when the stirring shaft 10 rotates. The lower rotating component 12 is connected to the bottom of the locking disc 3 via a belt and pulley, and it can drive the locking disc 3 when it rotates. The insert rod 13 is set at the bottom of the upper rotating component 11 via a universal joint, thereby realizing the adjustment and transmission of angle or direction. One end of the sleeve 14 is also installed at the top of the lower rotating component 12 via a universal joint, ensuring smooth power transmission during the transmission process. Through the cooperation of the insert rod 13 and the sleeve 14, a stable linkage relationship is formed between the upper rotating component 11 and the lower rotating component 12. While the stirring shaft 10 rotates, the locking disc 3 is driven to rotate synchronously through the linkage component, thereby ensuring the efficient and coordinated completion of the stirring and locking functions.

[0026] In some examples, the sleeve 14 is further provided with a movable groove 15, and the insert rod 13 is equipped with a slider 16 that can reciprocate within the movable groove 15. During operation, when the insert rod 13 rotates with the linkage assembly or moves axially, the slider 16 can reciprocate within the movable groove 15. When the upper frame 2 needs to be raised, the cylinder 9 pushes the insert rod 13 to move within the movable groove 15 of the sleeve 14, without affecting the transmission of power from the drive component 8 to the locking disc 3 and the stirring shaft 10 through the insert rod 13 and the sleeve 14, thus ensuring the feasibility of the upper frame 2's rotatable raising and stirring functions.
