Abstract
Description
Technical Field
[0001] This utility model relates to the field of meat processing technology, specifically to a meat mixing device. Background Technology
[0002] The core of meat mixing lies in achieving homogenization and textural improvement of materials through mechanical force. Essentially, it utilizes the shearing, kneading, and tumbling action of mixing elements to ensure thorough contact between the meat raw materials and added ingredients (such as seasonings and auxiliary materials) at both macroscopic and microscopic levels, forming a stable system. This eliminates uneven component distribution and ensures consistency in the flavor and quality of the finished product. Simultaneously, the mechanical action generated during mixing alters the muscle fiber structure of the meat, breaking down some intermuscular connective tissue and changing the physical properties of the meat, such as improving water retention and binding properties, laying the foundation for a uniform and stable texture in subsequent processing.
[0003] A meat mixer disclosed in authorization announcement number (CN222302904U) includes a mixing chamber. The bottom of both the front and back sides of the mixing chamber's inner cavity has slides, and partitions are movably connected within these slides via movable shafts. A drive mechanism is also installed at the bottom of the mixing chamber's inner cavity. In operation, the meat products to be mixed and seasonings are first placed into the mixing chamber for mixing. When the meat products are mixed and need to be discharged, the drive mechanism causes the left side of the partition to flip downwards, tilting the partition. The meat products at the top of the partition then slide down to the left, thus quickly discharging the meat products from the mixing chamber.
[0004] The structure disclosed in this patent has shortcomings in practical application, specifically as follows: the discharge mechanism relies on the weight of the meat sliding down an inclined baffle, but the tilting angle of the baffle is limited by the mechanical stroke of the slide and drive mechanism, resulting in a significant limitation on the tilt angle. For meats with high viscosity or a firm texture, this limited tilt angle cannot provide sufficient potential energy to overcome the adhesion between the material and the baffle surface, making it difficult for the meat to slide completely and easily leaving residue on the baffle surface. This not only reduces the thoroughness of discharge and causes material loss, but also increases the complexity of equipment cleaning and operating costs due to the adhesion of residual material. Utility Model Content
[0005] The purpose of this invention is to provide a meat mixing device that addresses the problem in existing meat mixers where the limited tilt angle of the baffles leads to incomplete discharge of highly viscous or dense meat materials. This invention improves the flexibility of the discharge angle, effectively solves the problem of residue in the discharge of highly viscous or dense meat, and reduces cleaning difficulty.
[0006] This utility model is achieved through the following technical solution:
[0007] A meat mixing device includes: a base; two support frames mounted on opposite sides of the base; a mixing spindle with both ends rotatably connected to the support frames; a mixing housing disposed between the two support frames, with rotating interfaces at both ends of the mixing housing, the rotating interfaces forming a rotatable fit with the mixing spindle, the mixing housing being able to be locked at a preset angle around the mixing spindle; multiple mixing blades mounted on the outer wall of the mixing spindle, with a safety clearance between the rotation trajectory of the mixing blades and the inner wall of the mixing housing; and a drive assembly mounted on the base and drivingly connected to the mixing spindle.
[0008] Furthermore, in this utility model, a positioning lock frame is installed on the outer wall of the above-mentioned stirring shell. The positioning lock frame extends along the circumferential direction of the stirring shell and has multiple positioning lock holes along the extension direction. A locking component is installed on the support frame. The locking component can be engaged and locked with the preset positioning lock holes, so as to perform positioning and locking after the stirring shell is rotated to a preset angle.
[0009] Furthermore, in this utility model, the locking assembly includes: two guide bushings, which are respectively installed on both sides of the support frame; two locking pins, which are respectively inserted into the guide bushings and can reciprocate along the extension direction of the guide bushings; a synchronizing link, which is installed between the two locking pins to form a synchronous linkage structure, and the synchronizing link has a positioning guide hole; a guide spindle, one end of which is connected to the support frame and the other end of which passes through the positioning guide hole; and a return spring, which is fitted on the outside of the guide spindle, one end of which is connected to the support frame and the other end of which is connected to the synchronizing link.
[0010] Furthermore, in this utility model, the above also includes an anti-retraction pin; the guide spindle is provided with an anti-retraction pin hole adapted to the anti-retraction pin. When the locking pin is engaged with the positioning lock hole, the anti-retraction pin can be inserted into the anti-retraction pin hole to prevent the synchronous connecting rod from moving backward in the direction away from the positioning lock hole, thereby maintaining the engagement state of the locking pin and the positioning lock hole.
[0011] Furthermore, in this invention, the end of the locking pin facing the positioning lock hole is provided with a guide arc, so that the locking pin can guide and cooperate with the positioning lock hole.
[0012] Furthermore, in this invention, a material-blocking end cap is detachably installed at the top opening of the stirring shell, which is used to prevent material from overflowing from the top of the stirring shell.
[0013] Furthermore, in this utility model, the aforementioned drive assembly includes: a motor bracket connected to the base; and a drive motor mounted on the motor bracket, with the output end of the drive motor connected to the stirring shaft.
[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:
[0015] 1. The multi-angle locking and overall flipping design of the mixing shell in this application can simultaneously meet the requirements of thorough discharge and stable mixing operation for highly viscous or firm meats. The rotational cooperation between the mixing shell and the mixing spindle enables multi-angle adjustment, and the locking component can fix the mixing shell at a preset angle. The mixing shell can rotate around the mixing spindle to a near-vertical discharge angle, providing sufficient potential energy for highly viscous or firm meats to overcome adhesion, avoiding material residue caused by insufficient discharge angle, and improving the thoroughness of discharge.
[0016] 2. The synchronous linkage mechanism of the locking component in this application, combined with the guide arc structure, forms a highly efficient angle adjustment and positioning system. The locking component achieves the coordinated action of the double locking pins through the synchronous linkage, and the matching and cooperation between the guide arc and the positioning lock hole forms an automatic unlocking guide structure. This structure can automatically disengage when the mixing shell is rotated to simplify the adjustment process, and can also maintain a stable locked state during mixing operations. This effectively reduces the difficulty of single-person operation and improves the convenience of angle adjustment and the safety of equipment operation. Attached Figure Description

Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0026] Example
[0027] Please refer to Figures 1 to 4 This utility model provides a meat mixing device. It includes a base 1, two support frames 2, a mixing main shaft 4, a mixing housing 3, multiple mixing blades 19, and a drive assembly. The two support frames 2 are correspondingly installed on opposite sides of the base 1. The mixing housing 3 is disposed between the two support frames 2. Rotation interfaces 15 are provided at both ends of the mixing housing 3. The mixing main shaft 4 passes through the rotation interfaces 15 into the mixing housing 3. The mixing main shaft 4 and the rotation interfaces 15 are rotatably coupled via bearings, allowing the mixing main shaft 4 to rotate relative to the mixing housing 3.
[0028] Two support frames 2 pass through both ends of the mixing spindle 4. The mixing spindle 4 and the support frames 2 are rotatably connected by bearings. The mixing housing 3 can rotate around the mixing spindle 4 and be locked at a preset angle. Multiple mixing blades 19 are assembled on the outer wall of the mixing spindle 4, and a safety clearance is reserved between the rotation trajectory of the mixing blades 19 and the inner wall of the mixing housing 3. The drive assembly is mounted on the base 1 and is connected to one end of the mixing spindle 4. The drive assembly can drive the mixing spindle 4 to rotate, thereby driving the multiple mixing blades 19 to rotate inside the mixing housing 3 to achieve the mixing of meat.
[0029] When mixing meat, rotate the mixing shell 3 to the position with the opening facing upwards and lock it. Then, put the meat and seasonings into the mixing shell 3. The drive assembly drives the mixing shaft 4 and the mixing blades 19 to rotate inside the mixing shell 3 to complete the meat mixing operation. When it is time to remove the meat after mixing, adjust the rotation of the mixing shell 3 to the preset direction. The angle of the opening of the mixing shell 3 facing downwards can be adjusted according to the viscosity of the meat. After adjustment, lock the mixing shell 3 at the corresponding angle to facilitate the removal of the meat from the mixing shell 3.
[0030] Among them, a mechanical seal assembly is provided at the fitting gap between the stirring main shaft 4 and the rotating interface 15, which can effectively prevent the material in the stirring shell 3 from overflowing outward through the fitting gap.
[0031] It should be noted that the cross-section of the stirring shell 3 is circular, and the cross-sectional profile of the stirring shell 3 is adapted to the trajectory profile formed by the rotation of multiple stirring blades 19. Based on this structural design, when the stirring shell 3 rotates along the stirring main shaft 4, a safe gap can always be maintained between the inner wall of the stirring shell 3 and each stirring blade 19, thereby ensuring that there is no interference between the two during relative motion.
[0032] Please refer to Figure 1 and Figure 2 In some embodiments of this application, a positioning lock frame 5 is installed on the outer wall of the stirring shell 3. The positioning lock frame 5 extends along the circumferential direction of the stirring shell 3, and the curvature of the positioning lock frame 5 is adapted to the curvature of the outer wall of the stirring shell 3. The positioning lock frame 5 is provided with a plurality of positioning lock holes 6 at intervals along its own extension direction. A locking component is assembled on the support frame 2. When the stirring shell 3 rotates around the stirring main shaft 4, the positioning lock frame 5 rotates synchronously with the stirring shell 3. During the rotation, the positioning lock frame 5 can align the positioning lock holes 6 at preset positions with the locking component. The locking component can form an engagement lock with the preset positioning lock holes 6 to achieve positioning and fixing of the stirring shell 3 at a preset angle.
[0033] Please refer to Figure 2 Specifically, the locking assembly includes two guide bushings 7, two locking pins 8, a synchronous connecting rod 9, a guide spindle 10, and a return spring 11. The two guide bushings 7 are fixedly mounted on both sides of the support frame 2, and the two locking pins 8 are correspondingly inserted into the guide bushings 7. The locking pins 8 can reciprocate along the axial direction of the guide bushings 7 to achieve engagement or disengagement with the positioning lock holes 6. The synchronous connecting rod 9 is connected between the two locking pins 8 to form a synchronous linkage structure, and a positioning guide hole 18 is provided on the synchronous connecting rod 9. One end of the guide spindle 10 is fixedly connected to the support frame 2, and the other end is inserted into the positioning guide hole 18 to form a sliding fit. The return spring 11 is sleeved on the outside of the guide spindle 10, and one end of the return spring 11 is connected to the support frame 2, and the other end is connected to the synchronous connecting rod 9.
[0034] When the return spring 11 is in its natural state, the two locking pins 8 are respectively engaged in the corresponding positioning lock holes 6. When the stirring shell 3 is released from its lock, the operator pulls the synchronous connecting rod 9 to move it away from the stirring shell 3. The synchronous connecting rod 9 drives the two locking pins 8 to disengage from the positioning lock holes 6 simultaneously. At this time, the return spring 11 is stretched and stored. After the stirring shell 3 rotates to the preset angle, the operator releases the pulling force on the synchronous connecting rod 9. The synchronous connecting rod 9 is reset under the elastic restoring force of the return spring 11, which drives the two locking pins 8 to engage in the corresponding positioning lock holes 6, completing the repositioning of the stirring shell 3 and fixing the stirring shell 3 in the new angular position.
[0035] Please refer to Figure 2 and Figure 3 In some embodiments of this application, the guide spindle 10 is provided with an anti-retraction pin hole 16 that is adapted to the anti-retraction pin 17. When the locking pin 8 is engaged in the positioning lock hole 6, the anti-retraction pin 17 can be inserted into the anti-retraction pin hole 16 to form a rigid block on the synchronous connecting rod 9 moving away from the positioning lock hole 6, thereby maintaining the engagement state of the locking pin 8 and the positioning lock hole 6.
[0036] When the return spring 11 is in its natural state, the synchronous link 9 is positioned at the preset position of the guide spindle 10. At this time, the two locking pins 8 are respectively engaged in the positioning lock hole 6, and the anti-retraction pin hole 16 is located on the rear side of the synchronous link 9. The operator can screw the anti-retraction pin 17 into the anti-retraction pin hole 16 through the threaded engagement to form a rear limit on the synchronous link 9, restricting the synchronous link 9 from moving away from the positioning lock hole 6, thereby preventing the locking pin 8 from accidentally disengaging from the positioning lock hole 6, ensuring the locking stability of the stirring shell 3 during the stirring operation, and avoiding the failure of the locking mechanism due to vibration generated by stirring.
[0037] Please refer to Figure 5In some embodiments of this application, the end of the locking pin 8 facing the positioning lock hole 6 is provided with a guide arc 20 structure, which can form an adaptive guiding fit with the positioning lock hole 6. When the operator adjusts the angle of the stirring shell 3, the anti-retraction pin 17 is first removed from the anti-retraction pin hole 16 to release the rear limit of the synchronous link 9; at this time, there is no need for external force to pull the synchronous link 9 to make the locking pin 8 disengage from the positioning lock hole 6, and the stirring shell 3 can be directly driven to rotate, which can drive the positioning lock frame 5 to rotate synchronously. The inner wall of the positioning lock hole 6 will contact the guide arc 20 at the end of the locking pin 8 and form a guiding effect, forcing the locking pin 8 to automatically retract and disengage from the positioning lock hole 6 under the action of the contact component force, so as to realize the smooth rotation of the stirring shell 3; when the stirring shell 3 rotates to the preset angle, the two locking pins 8 will automatically embed into the corresponding positioning lock hole 6 under the action of the elastic force of the return spring 11, and then the anti-retraction pin 17 is installed into the anti-retraction pin hole 16 to complete the locking of the synchronous link 9. The aforementioned adjustment structure simplifies the operation process, and with locking components configured on both support frames 2, a single operator can independently complete the angle adjustment operation.
[0038] Please refer to Figure 1 In some embodiments of this application, a material-blocking end cap 12 is detachably fitted at the top opening of the mixing shell 3. The material-blocking end cap 12 is used to block the material during the mixing process to prevent the material from overflowing from the top of the mixing shell 3. When meat is being mixed, it tends to be thrown up due to the action of the mixing blades 19. The material-blocking end cap 12 intercepts the material inside the mixing shell 3, preventing the material from splashing outward under the action of centrifugal force or impact force.
[0039] Specifically, the edge of the material blocking end cap 12 is equipped with a buckle, and the corresponding position of the top opening of the mixing shell 3 is provided with a slot that matches the buckle. The buckle can be elastically inserted into the slot to form a locking fit, so as to realize the detachable connection between the material blocking end cap 12 and the mixing shell 3. This ensures the connection stability between the two during the mixing process and makes it easy for operators to quickly disassemble and assemble the material blocking end cap 12 to complete the feeding and taking out of materials.
[0040] Please refer to Figure 1 In some embodiments of this application, the drive assembly includes a motor bracket 13 and a drive motor 14; the motor bracket 13 is rigidly connected to the base 1, and the motor bracket 13 provides support for the drive motor 14 to ensure that it remains in a fixed position during operation and avoids displacement due to vibration; the drive motor 14 is mounted in a preset mounting position on the motor bracket 13, and the output end of the drive motor 14 is connected to the stirring shaft 4 to provide continuous power for the stirring operation of materials in the stirring shell 3.

It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
