Description

Technical Field

[0001] This utility model relates to the field of meat grinders, specifically to a chain-driven high-grinding meat grinder. Background Technology

[0002] Current meat grinder technology generally employs a single-stage transmission mechanism driven by a motor to rotate the auger, thereby cutting and crushing the meat raw materials to achieve mincing. However, existing meat grinders commonly suffer from insufficient driving force, low grinding efficiency, and a tendency to jam when processing raw materials with a lot of fascia or firm meat, severely affecting their performance and stability. Furthermore, in terms of the transmission system, most use direct belt or gear drives, resulting in a simple structure that cannot meet the demands of high grinding force and continuous heavy-load operation. In addition, the maintenance and adjustment of existing meat grinders are relatively cumbersome, especially in terms of adjusting the transmission belt tension, which is mostly done manually. This method has low adjustment precision, easily causing belt slippage or reduced transmission efficiency, affecting the long-term stable operation of the equipment.

[0003] Regarding meat grinding mechanisms, traditional augers and blades are often connected by plug-in or snap-fit ​​connections, which are not secure and are prone to loosening or shifting under high loads, resulting in uneven cutting or damage to the blades. On the other hand, existing feeding structures are also relatively simple, usually consisting of only a vertical feed inlet without necessary limiting or guiding structures, making them prone to blockages during feeding, affecting feeding efficiency and the continuity of equipment operation. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a chain-driven high-strength meat grinder, which effectively overcomes the shortcomings of existing technologies.

[0005] This utility model is achieved through the following technical solution: a chain-driven high-strength meat grinder, comprising: A chassis, wherein a drive mechanism is installed inside the chassis; A three-way meat grinder is installed outside the machine housing. A meat grinder is installed inside the three-way meat grinder, which grinds the meat that is being transported in and then outputs it. A meat tray is installed on the top of the machine housing. The output end of the meat tray is provided with a feed inlet. The meat to be minced enters the three-way meat grinding tube through the feed inlet. A limiting baffle is provided on the meat tray, and a material passage is formed between the lower end face of the limiting baffle and the meat tray; The drive mechanism includes: A drive motor is fixedly mounted on an adjusting mounting plate, and a drive pulley is installed at the output end of the drive motor; A gear bearing housing is fixedly installed on the inner side of the chassis and is positioned directly opposite the three-way meat grinder pipe. A first double chain tooth and a second double chain tooth are installed on the gear bearing housing. A double chain is installed on the first double chain tooth and the second double chain tooth, and a driven pulley is coaxially installed on the input end of the first double chain tooth; Multiple sets of transmission belts are installed on the driving pulley and the driven pulley, and the tension of the transmission belts is adjusted by adjusting the height of the adjusting mounting plate.

[0006] As a preferred technical solution, a first transmission shaft and a second transmission shaft are mounted in the gear bearing housing via bearings. The first double chain tooth and the driven pulley are both fixedly mounted on the first transmission shaft, and the second double chain tooth is fixedly mounted on the second transmission shaft.

[0007] As a preferred technical solution, one end of the second drive shaft extends into the three-way meat grinder tube, and the meat grinder mechanism is docked and fixed with the second drive shaft, thereby driving the meat grinder mechanism to rotate.

[0008] As a preferred technical solution, the meat grinding mechanism includes: An auger, which is fixedly connected to one end of the second drive shaft; The auger includes a cross-shaped cutter, a auger shaft, and a round cutter. The auger shaft is fixedly connected to the auger by a thread, and the cross-shaped cutter and the round cutter are both fixedly mounted on the auger shaft.

[0009] As a preferred technical solution, a three-way sealing nut is installed on the outside of the three-way meat grinder tube, and an operating handle is provided on the outer circular surface of the three-way sealing nut.

[0010] As a preferred technical solution, the circular knife is provided with one or more small holes for meat discharge.

[0011] As a preferred technical solution, one end of the adjustment mounting plate is rotatably mounted on the first hinge seat inside the chassis via a first rotating pin, and the other end of the adjustment mounting plate is provided with at least two threaded adjustment rods. The threaded adjustment rods pass through the adjustment mounting plate, and locking nuts are respectively provided on the upper and lower surfaces of the threaded adjustment rods. The threaded adjusting rod is provided with second rotating pins on both sides of its bottom, and the threaded adjusting rod is rotatably mounted on the second hinge seat inside the chassis via the second rotating pins at the bottom.

[0012] As a preferred technical solution, the bottom surface of the limiting baffle is an inclined guide surface, and the guiding direction is towards the feed inlet.

[0013] As a preferred technical solution, the number of transmission belts is at least three.

[0014] The beneficial effects of this utility model are: The chain-driven high-force meat grinder provided by this utility model achieves efficient and powerful drive of the meat grinding mechanism by adopting a chain drive structure with sprocket and double chain, which significantly improves the output force of the whole machine, enabling it to stably process large pieces of meat and tough meat materials such as those containing tendons and membranes, and overcomes the problems of traditional meat grinders being prone to jamming and incomplete meat grinding. The system employs a multi-belt transmission structure. By adjusting the threaded adjusting rod on the mounting plate and cooperating with the locking nut, the belt tension can be precisely adjusted, avoiding power loss caused by belt slack and improving the reliability and ease of maintenance of the transmission system. In terms of the meat grinding mechanism, by sequentially and threadedly connecting the auger, auger shaft, cross blade and round blade, and directly driving them by the second drive shaft, not only is the coaxial rotation of the blades and the auger and the stability of operation guaranteed, but also the uniformity of meat cutting and the meat output efficiency are improved. Meanwhile, the T-shaped sealing nut located on the outside of the T-shaped meat grinder tube is equipped with an operating handle, which facilitates quick assembly and cleaning maintenance, improving user convenience. In addition, the meat tray is equipped with a limit baffle with an inclined guide surface at the bottom, which can guide the meat to enter the feed inlet smoothly, reduce the risk of blockage caused by accumulation during the feeding process, and ensure continuous and efficient operation.

Detailed Implementation

[0017] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.

[0018] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0019] like Figures 1-4 As shown, this utility model discloses a chain-driven high-strength meat grinder, which includes components such as a housing 1, a three-way meat grinding pipe 7, a meat tray 2, a meat grinding mechanism, and a drive mechanism.

[0020] Among them, the chassis 1 is the foundation for the entire machine to bear and install, and the drive mechanism is installed inside it. The drive mechanism is used to provide strong and stable transmission power to the meat grinding mechanism.

[0021] The three-way meat grinder 7 is installed on the outer side wall of the casing 1. Its inner cavity is equipped with a meat grinder mechanism for cutting and outputting meat. The meat grinder mechanism completes the grinding of raw meat under the drive of the drive mechanism.

[0022] The meat tray 2 is installed on the top of the casing 1, serving as a platform for carrying and conveying raw meat. A feed inlet 4 is provided at the bottom of the meat tray 2, allowing the raw meat to enter the three-way meat grinder 7 by gravity or a pressure device, thus completing the feeding process.

[0023] To prevent lumpy or oversized raw materials from entering the meat grinding mechanism and causing blockage or damage, a limiting baffle 3 is provided on the upper part of the meat tray 2. The lower end face of the limiting baffle 3 forms a material passage between the meat tray 2 and the material passage, which restricts the size and stacking height of the raw materials entering.

[0024] Furthermore, the bottom surface of the limiting baffle 3 is an inclined guide surface facing the feed inlet 4, which can automatically guide the raw materials piled up in front of the baffle to the direction of the feed inlet 4, thereby improving feeding efficiency and reducing the risk of material jamming.

[0025] The drive mechanism is located inside the housing 1, and its core power source is a drive motor. This drive motor is fixedly mounted on an adjustable mounting plate 17. The structure of the adjustable mounting plate 17 allows for adjustment of the motor's position and height, which facilitates control of belt tension. A drive pulley 11 is provided on the output shaft of the drive motor to output power to the subsequent transmission structure.

[0026] To achieve high twisting force output, the drive mechanism incorporates a two-stage sprocket and chain structure, equipped with a gear bearing housing 8. This gear bearing housing 8 is fixed to the inner wall of the housing 1 and faces the three-way meat grinder pipe 7, facilitating the construction of a power transmission path from the drive motor to the meat grinder mechanism. The gear bearing housing 8 is equipped with a first double chain tooth 9 and a second double chain tooth 13, which are used to construct the transmission path of the double chain 14.

[0027] The driving pulley 11 is connected to the driven pulley 12, which is coaxially arranged at the input end of the first double chain tooth 9, through multiple sets of transmission belts 10. Preferably, there are three or more transmission belts 10. The multi-belt parallel structure improves transmission stability and anti-slip capability.

[0028] The drive belt 10 is installed between the driving pulley 11 and the driven pulley 12, and the tension can be adjusted by adjusting the height of the mounting plate 17.

[0029] Specifically, one end of the adjusting mounting plate 17 is hinged to the first hinge seat 16 inside the chassis 1 via the first rotating pin 15, and the other end is height-adjusted to the lower support structure of the chassis 1 via at least two threaded adjusting rods 18.

[0030] Each threaded adjusting rod 18 passes through the adjusting mounting plate 17 and has locking nuts 20 on both its upper and lower sides for locking the adjusting position. Second rotating pins 21 are provided on both sides of the bottom of the adjusting rod, and are rotatably mounted on the second hinge seats 19. The angle of the adjusting mounting plate 17 is adjusted by a screw lifting mechanism, thereby indirectly controlling the tension of the belt, improving maintenance efficiency and transmission reliability.

[0031] Inside the gear bearing housing 8, a first drive shaft 23 and a second drive shaft 22 are respectively mounted via bearings. The first double chain tooth 9 and the driven pulley 12 are both fixedly mounted on the first drive shaft 23. The first drive shaft 23 acts as a power receiving shaft, converting the rotational output of the pulley into the rotation of the sprocket, which in turn drives the second double chain tooth 13 to rotate via the double chain 14. The second double chain tooth 13 is fixedly mounted on the second drive shaft 22. One end of the second drive shaft 22 passes through the wall of the housing 1 and extends into the three-way meat grinder tube 7, where it is reliably connected to the meat grinder mechanism, thus efficiently outputting transmission power to the meat grinder mechanism.

[0032] The meat grinding mechanism includes key components such as an auger 24, a cross blade 26, a shaft 25, and a circular blade 5. The auger 24 is directly connected and fixedly connected to the front end of the second drive shaft 22 via its tail, achieving coaxial transmission. The shaft 25 is an intermediate connecting component; one end is firmly connected to the front end of the auger 24 via a thread, and the other end is sequentially equipped with the cross blade 26 and the circular blade 5. The cross blade 26 is used for initial crushing of meat chunks, while the circular blade 5 has multiple small meat outlet holes for fine cutting and meat paste output, ultimately creating a multi-stage shearing and extrusion effect on the meat, improving the fineness and uniformity of the mincing.

[0033] To facilitate disassembly, cleaning, and maintenance, a three-way sealing nut 6 is installed on the outside of the discharge end of the three-way meat grinder tube 7. The outer surface of the nut is equipped with an operating handle for easy manual operation. Users can quickly tighten or loosen the nut to disassemble and reassemble the meat grinder mechanism, thereby improving the ease of use and hygiene safety of the whole machine.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
