Description

Technical Field

[0001] This utility model relates to the field of beef product processing, specifically to a beef grinding device. Background Technology

[0002] Ground beef is a crucial pre-processing step in food processing, driven by the inherent requirements of ingredient characteristics, processing techniques, and product needs. From an ingredient perspective, beef muscle fibers are coarse and rich in connective tissue; grinding breaks down this fiber structure, softening the meat and increasing its contact area with seasonings, significantly improving marinating efficiency and flavor penetration. From a processing perspective, grinding transforms beef from chunks into uniform granules or a paste, meeting the material form requirements of different products. For example, beef balls require a fine paste to ensure elasticity, while beef burger fillings need to retain a certain texture for a unique flavor. From a product demand perspective, ground beef adapts to diverse cooking and consumption scenarios. Industrialized foods such as frozen dumplings and canned goods rely on grinding to standardize product forms, improve production efficiency and ease of consumption, optimize product structure, extend shelf life, and enhance market competitiveness.

[0003] A beef processing and grinding device disclosed in authorization announcement number (CN222401730U) includes a mounting frame, a cylindrical outer shell fixed to the top of the mounting frame, a discharge plate with several through holes at the front end of the outer shell, and a rear cover at the rear end of the outer shell. An inlet port is located at the top of the discharge plate near the rear end. In use, beef is fed into the device through the inlet port. Rotating a rocker arm drives a rotating shaft and blades to rotate, thus grinding the beef. Finally, the beef is discharged from the discharge plate. In actual operation, beef is introduced through the inlet port, and the rocker arm drives the rotating shaft and blades to form a rotary shearing motion, grinding the beef inside the cylindrical outer shell. The ground beef is then discharged through the through holes on the surface of the discharge plate.

[0004] The structure disclosed in this patent has shortcomings in practical applications. Specifically, in the food processing field, different product categories have significantly different requirements for the texture of ground beef. For example, the fineness of the meat paste required for beef product shaping and the particle size requirement for filling products both depend on different specifications of ground meat particle size. A discharge plate with a fixed aperture cannot achieve dynamic adjustment of the ground meat particle size, and therefore cannot adapt to the differentiated technical requirements of different products for ground meat particle size. Utility Model Content

[0005] The purpose of this utility model is to provide a beef grinding device that addresses the problem in the prior art where the fixed aperture discharge plate cannot dynamically adjust the minced meat particle size, making it difficult to adapt to the different needs of various products for beef particles. This device provides a solution that enables dynamic adjustment of the minced meat particle size to meet the different needs of various beef products for particle size.

[0006] This utility model is achieved through the following technical solution:

[0007] A beef grinding device includes: a frame; a grinding cylinder mounted on the frame, with an inlet port at the top and an outlet port at one end; a screen assembly mounted at the outlet port, having multiple screen interfaces; multiple screen plates detachably mounted on corresponding screen interfaces, each screen having multiple pre-set holes; a grinding assembly disposed within the grinding cylinder, one end of which is rotatably connected to the inner wall of the grinding cylinder, and the other end of which is rotatably connected to the screen assembly; and a drive assembly mounted on the frame, capable of driving the grinding assembly to grind meat.

[0008] Furthermore, in this utility model, the above-mentioned auger screen assembly includes: an auger screen base plate, which is disposed inside the discharge port; and multiple positioning shafts, which are distributed along the circumferential direction of the discharge port, with one end of the positioning shaft connected to the inner wall of the discharge port and the other end of the positioning shaft connected to the auger screen base plate, and an auger screen interface formed between two adjacent positioning shafts.

[0009] Furthermore, in this utility model, the above also includes a positioning pin; a first pin hole is provided at the top of the screen plate; a plurality of second pin holes are provided at the discharge port of the meat grinder cylinder along the circumferential direction, and the plurality of second pin holes extend into the corresponding screen interface respectively; wherein, when the screen plate is fully installed in the screen interface, the first pin hole and the second pin hole are aligned, and the positioning pin can pass through the second pin hole and the first pin hole in sequence to realize the positioning of the screen plate.

[0010] Furthermore, in this utility model, the discharge port of the above-mentioned meat grinder cylinder is provided with multiple main guide grooves along the circumferential direction, and the multiple main guide grooves are respectively distributed in the corresponding sieve interface; the sieve plate is provided with multiple secondary guide grooves along the circumferential direction, and the multiple secondary guide grooves are respectively distributed in the corresponding sieve interface; the top of the sieve plate is provided with a main guide body that guides and cooperates with the main guide grooves, and the bottom of the sieve plate is provided with a secondary guide body that guides and cooperates with the secondary guide grooves.

[0011] Furthermore, in this utility model, a front limiting ring is installed on one side of the aforementioned winch screen base plate along the circumferential direction, and the front limiting ring can cooperate with the screen plate for limiting; a rear limiting ring is detachably installed on the other side of the winch screen base plate, and the rear limiting ring can cooperate with the screen plate for limiting; wherein, the front limiting ring and the rear limiting ring can restrict the screen plate within the winch screen interface.

[0012] Furthermore, in this utility model, the above-mentioned sieve assembly includes: a rotating main shaft, which is disposed in the meat grinder cylinder, one end of which is rotatably connected to the inner wall of the meat grinder cylinder, and the other end of which is rotatably connected to the sieve base plate; and spiral cutting blades, which are installed on the outer wall of the rotating main shaft and arranged along the extension direction of the rotating main shaft.

[0013] Furthermore, in this utility model, the aforementioned drive assembly includes: a bracket mounted on a frame; and a drive motor mounted on the bracket, the output end of which is connected to a rotating spindle.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0015] 1. The sieve assembly and sieve plate of the beef grinding device in this application adopt a detachable design. Multiple sieve plates are respectively installed at the sieve interface. Each sieve plate can be configured with different sieve hole parameters to form an independent particle size control unit. When the sieve plate is fixed at the sieve interface, the sieve hole structure of the sieve plate cooperates with the meat grinding assembly to achieve differentiated control of beef particle size from a mechanism perspective. This effectively avoids the problem of single particle size caused by traditional fixed hole structure, and is especially suitable for beef product processing scenarios that require multiple particle sizes.

[0016] 2. In this application, the front limiting ring and the rear limiting ring are distributed along both sides of the auger screen base plate, forming a three-dimensional limiting system with the positioning pin. The front limiting ring restricts the displacement of the front end of the screen plate, the rear limiting ring constrains the rear end of the screen plate, and the positioning pin locks the top position of the screen plate. This eliminates the axial movement and radial offset of the screen plate during the auger screen operation from multiple dimensions, and ensures the stable fit between the screen plate and the auger screen interface from a structural perspective. This effectively avoids the problem of decreased particle size control accuracy caused by screen plate loosening, and is especially suitable for high-frequency vibration meat grinding conditions.

Detailed Implementation

[0026] 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.

[0027] Example

[0028] Please refer to Figures 1 to 5 This utility model provides a beef grinding device. It includes a frame 1, a grinding cylinder 2 mounted on the frame 1, a grinding assembly disposed within the grinding cylinder 2, a screen assembly 20 mounted at the discharge port 4 of the grinding cylinder 2, and a drive assembly connected to the grinding assembly. The grinding cylinder 2 has an inlet port 3 at its top and an outlet port 4 at one end. The screen assembly 20 includes multiple screen interfaces, each detachably fitted with a screen plate 9, and the screen plate 9 has evenly distributed grinding holes 10 of a preset diameter.

[0029] In actual operation, the operator feeds beef into the meat grinder cylinder 2 through the feed port 3. The drive component drives the meat grinder to work, so that the beef inside the meat grinder cylinder 2 is ground and crushed while moving. When the beef is conveyed to the screen assembly 20 at the discharge port 4, the beef that meets the particle size requirements is discharged through the abrasion holes 10 of the screen plate 9 and is collected. The beef that does not meet the particle size requirements continues to be ground and crushed in the meat grinder cylinder 2 until the preset particle size is reached.

[0030] The operator can configure a screen plate 9 with differentiated grinding hole parameters at the grinding screen interface, which enables the device to form a coordinated control mechanism with the meat grinding component. When screen plates 9 of different specifications are installed at the corresponding grinding screen interface, the particle size of the ground beef can be flexibly controlled, thereby meeting the diverse requirements of different products for the particle size of ground meat in the process standards.

[0031] Please refer to Figure 3 and Figure 4 In some embodiments of this application, the winch screen assembly 20 includes a winch screen base plate 15 disposed inside the discharge port 4, and a plurality of positioning support shafts 8 evenly distributed along the circumference of the discharge port 4. One end of the positioning support shaft 8 is connected to the inner wall of the discharge port 4, and the other end is connected to the edge of the winch screen base plate 15. A winch screen interface for mounting the screen plate 9 is formed between two adjacent positioning support shafts 8.

[0032] A circular screen base plate 15 is supported at the center of the discharge port 4 by multiple positioning shafts 8. Multiple screen interfaces are evenly distributed along the circumference of the screen base plate 15, and each screen interface corresponds to a screen plate 9. The screen plate 9 is detachably installed in the corresponding screen interface, thereby controlling the beef particle size during the meat grinding process.

[0033] Please refer to Figure 4 and Figure 5 In some embodiments of this application, a first pin hole 19 is provided at the top of the screen plate 9, and a plurality of second pin holes 11 are provided at the discharge port 4 of the meat grinder cylinder 2 along the circumferential direction. The plurality of second pin holes 11 extend into the corresponding screen interface. The outer contour of the screen plate 9 is adapted to the inner contour of the screen interface, and the screen plate 9 can be precisely inserted into the screen interface. When the screen plate 9 is fully installed in the screen interface, the first pin hole 19 on the screen plate 9 and the second pin hole 11 on the discharge port 4 are coaxially aligned, and the positioning pin 12 can be inserted into the second pin hole 11 and the first pin hole 19 in sequence. The positioning pin 12 forms a threaded engagement with the second pin hole 11 and the first pin hole 19 respectively, thereby fixing the screen plate 9 in the screen interface. The screen plate 9 can intercept the beef in the meat grinder cylinder 2, allowing only beef that meets the particle size standard to be discharged through the screen hole 10 on the screen plate 9.

[0034] It should be noted that a rubber ring is embedded on the outer periphery of the sieve plate 9. During the installation of the sieve plate 9 at the auger interface, the rubber ring will undergo elastic deformation due to the assembly and compression of the sieve plate 9 and the auger interface, thereby tightly filling the gap between the auger interface and the sieve plate 9. The deformation and filling effect of the rubber ring can effectively prevent beef particles that do not reach the preset particle size from being directly discharged from the gap, ensuring that all beef must be screened through the auger holes 10 of the sieve plate 9 before being discharged from the meat grinder cylinder 2, thus ensuring the reliability of beef particle size control.

[0035] Please refer to Figure 4 and Figure 5In some embodiments of this application, the discharge port 4 of the meat grinder cylinder 2 is provided with multiple main guide grooves 13 along the circumferential direction, and each main guide groove 13 is respectively distributed in the top area of ​​the sieve interface; the outer periphery of the sieve base plate 15 is provided with multiple secondary guide grooves 16 along the circumferential direction, and each secondary guide groove 16 is respectively distributed in the bottom area of ​​the sieve interface. The top end of the sieve plate 9 is provided with a main guide body 14 that slides with the main guide groove 13, and the bottom end is provided with a secondary guide body 17 that slides with the secondary guide groove 16.

[0036] When the operator installs the screen plate 9, the main guide body 14 of the screen plate 9 is engaged into the corresponding main guide groove 13, and the secondary guide body 17 is simultaneously engaged into the corresponding secondary guide groove 16. This allows the screen plate 9 to move along a predetermined trajectory within the sieve interface to the installation position, achieving the positioning of the screen plate 9 and the sieve interface. This guiding structure not only effectively prevents circumferential offset during the installation of the screen plate 9, ensuring that the first pin hole 19 of the screen plate 9 and the second pin hole 11 of the meat grinder cylinder 2 are quickly aligned, but also enhances the vibration resistance stability of the screen plate 9 during the meat grinding process through the synergistic effect of the main and secondary guide bodies 17, further improving the reliability of the screen plate 9 in controlling the beef particle size.

[0037] Specifically, a front limiting ring 18 is installed circumferentially on one side of the winch screen base plate 15, and a rear limiting ring 7 is detachably installed on the other side. The front limiting ring 18 and the rear limiting ring 7 extend to the front and rear sides of each winch screen interface, respectively, and together form a limiting structure for the screen plate 9. When the screen plate 9 is fully slid into the winch screen interface, the end face of the front limiting ring 18 forms a limiting fit with the front end face of the screen plate 9, preventing the screen plate 9 from moving further into the winch screen interface. The rear limiting ring 7 is installed at the corresponding position on the winch screen base plate 15, and the end face of the rear limiting ring 7 forms a limiting fit with the rear end face of the screen plate 9. The distance between the front limiting ring 18 and the rear limiting ring 7 is adapted to the thickness of the screen plate 9, thereby firmly restricting the screen plate 9 within the winch screen interface.

[0038] The limiting structure and the positioning pin 12 together constitute a three-dimensional constraint on the screen plate 9, working together to ensure that the screen plate 9 maintains a stable installation state during the meat grinding process. When it is necessary to replace the screen plate 9 with different grinding hole 10 parameters, the operator can first remove the positioning pin 12 to release the constraint on the top of the screen plate 9, and then remove the rear limiting ring 7 from the grinding screen base plate 15, and slide the screen plate 9 out of the grinding screen interface to achieve quick replacement of the screen plate 9.

[0039] Please refer to Figure 2 and Figure 3For example, the rear limiting ring 7 has multiple first mounting holes along the circumferential direction, and the screen base plate 15 has multiple second mounting holes correspondingly along the circumferential direction. The multiple first mounting holes and multiple second mounting holes form a one-to-one correspondence. When it is necessary to fix the rear limiting ring 7, bolts are passed through the corresponding first and second mounting holes in sequence to fasten the rear limiting ring 7 to the screen base plate 15. At this time, the end face of the rear limiting ring 7 and the rear end face of the screen plate 9 form a tight abutment, thereby limiting the rear side of the screen plate 9. The detachable connection structure ensures the reliability of the rear limiting ring 7 in limiting the screen plate 9 and provides convenience for subsequent replacement of the screen plate 9. When it is necessary to remove the rear limiting ring 7, the bolts are removed to remove the rear limiting ring 7 from the screen base plate 15, thereby releasing the constraint on the rear side of the screen plate 9.

[0040] Please refer to Figure 6 In some embodiments of this application, the rotating main shaft 21 is arranged along the axial centerline of the meat grinder cylinder 2. One end of the rotating main shaft 21 is rotatably connected to the inner wall of the meat grinder cylinder 2 via a bearing assembly, and the other end of the rotating main shaft 21 is rotatably connected to the center of the sieve base plate 15 via a bearing assembly. The spiral cutting blades 22 are sleeved on the outer wall of the rotating main shaft 21 in a continuous spiral shape, and a uniform shearing gap is formed between the outer edge of the spiral cutting blades 22 and the inner wall of the meat grinder cylinder 2.

[0041] When the drive assembly drives the main shaft 21 to rotate, the spiral cutting blades 22 rotate synchronously. During the interaction between the spiral cutting blades 22 and the inner wall of the meat grinding cylinder 2, they not only generate axial propulsion force on the beef material, enabling continuous conveying of the beef from the inlet port 3 to the outlet port 4, but also crush the beef through the shearing action formed between the outer edge of the spiral cutting blades 22 and the inner wall of the meat grinding cylinder 2. This effectively simplifies the device structure and improves the meat grinding efficiency.

[0042] It should be noted that, to enhance the beef crushing effect, a shredding blade is fixedly installed at one end of the rotating main shaft 21. The shredding blade extends radially outward along the rotating main shaft 21, and the blade direction is adapted to the rotation direction of the rotating main shaft 21. It can rotate synchronously under the drive of the rotating main shaft 21, forming a preliminary cut on the beef entering the meat grinder cylinder 2. This works in conjunction with the crushing action of the spiral cutting blade 22 to further improve the uniformity and efficiency of beef crushing.

[0043] Please refer to Figure 1In some embodiments of this application, one end of the rotating main shaft 21 extends into the meat grinder cylinder 2 and forms a dynamic seal structure with the meat grinder cylinder 2 through a mechanical seal assembly. The output shaft of the drive motor 6 is connected to the extended end of the rotating main shaft 21. The power of the drive motor 6 can be transmitted to the spiral cutting blades 22. During this process, the spiral cutting blades 22 have a dual function as the rotating main shaft 21 rotates: on the one hand, the propulsive force of the spiral surface conveys the beef in the meat grinder cylinder 2 towards the discharge port 4; on the other hand, the shearing action between the edge of the spiral cutting blades 22 and the inner wall of the meat grinder cylinder 2 continuously crushes the beef. The mechanical seal assembly ensures the sealing reliability of the rotating main shaft 21 under high-speed rotation, and the transmission between the drive motor 6 and the rotating main shaft 21 provides a continuous and uniform power input to the spiral cutting blades 22.

[0044] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. 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.
