Description

Technical Field

[0001] This utility model relates to the field of meat grinder technology, and specifically to a meat grinding device. Background Technology

[0002] In existing meat grinders, the screws are mostly made of die-cast aluminum. However, this type of screw presents several problems in actual use. It is difficult to clean manually, and when placed in a dishwasher, the surface easily oxidizes and turns black, affecting not only its appearance but also its lifespan. Furthermore, die-cast aluminum has poor resistance to acids, alkalis, and salts; it is easily corroded when in contact with salt water or detergents, leading to damage to the screw structure and ultimately affecting food safety and hygiene.

[0003] For example, utility model patent CN209680271U discloses a manual stainless steel meat grinder, including a meat grinder body with a spiral shaft inside. One end of the spiral shaft is connected to the meat grinder body via a bushing, and the other end of the spiral shaft is fitted with a nut, which is threadedly connected to the meat grinder body. The shortcomings of this prior art are: its spiral shaft is made of die-cast aluminum, making cleaning inconvenient; the inner wall of its meat grinder body is smooth, resulting in poor meat grinding effect; and the small spacing between the spiral blades on its spiral shaft causes food to fall onto the outer edge of the spiral blades when entering the meat grinder body through the feed pipe, easily jamming the spiral shaft and affecting the feeding effect.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this utility model provides a meat grinding device. A spiral rib is provided around the inner wall of the grinding chamber, which, in conjunction with the screw, improves the meat grinding effect. A first pitch is formed between the spiral meat grinding blade and the outer wall of the central shaft. The first pitch is located below the feed pipe, and its width is greater than the diameter of the feed pipe. When food enters the grinding chamber through the feed pipe, it falls within the first pitch, resulting in better feeding. The grinding cylinder and screw are made of food-grade 304 stainless steel, 316 stainless steel, or 420 stainless steel, offering advantages such as durability and rust resistance. Furthermore, they are dishwasher safe for easy cleaning.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows: A meat grinding device includes a grinding cylinder and a screw. The grinding cylinder is provided with a feed pipe and has a grinding chamber formed inside. The inner wall of the grinding chamber is provided with spiral ribs. The screw is rotatably mounted in the grinding chamber and includes a central shaft. A first conical portion is formed at the first end of the central shaft, and a second conical portion is formed at the second end of the central shaft. Spiral meat grinding blades are provided on the outer wall of the central shaft between the first and second conical portions. A first pitch is formed between the spiral meat grinding blades and the outer wall of the central shaft. The first pitch is located below the feed pipe, and the width of the first pitch is greater than the diameter of the feed pipe. The grinding cylinder and the screw are made of food-grade 304 stainless steel, food-grade 316 stainless steel, or food-grade 420 stainless steel. This design features spiral ribs on the inner wall of the grinding chamber, which work in conjunction with the screw for better meat grinding. A first pitch is formed between the spiral meat grinder blades and the outer wall of the central shaft.

The grinding cylinder and screw are made of food-grade 304 stainless steel, 316 stainless steel, or 420 stainless steel, which are durable, rust-free, and dishwasher-safe for easy cleaning.

[0007] According to the above scheme, a second pitch is formed between the spiral-shaped meat grinder and the outer wall of the central shaft. One end of the second pitch is connected to the first pitch, and the width of the second pitch is smaller than the width of the first pitch. A discharge notch is formed at the other end of the second pitch, located on the outer wall of the second conical portion. This design facilitates the input of ingredients to fall into the first pitch and be smoothly pushed forward, resulting in a faster pushing speed. The width of the second pitch is smaller than the width of the first pitch, so the speed of the ingredients slows down after they reach the second pitch. The ingredients then spread outward from the discharge notch and distribute into the various holes of the cutter disc.

[0008] According to the above scheme, the first end of the screw has a threaded hole, and a drive head is fixed inside the threaded hole. A sealing assembly is provided between the drive head and the screw. This arrangement facilitates the assembly of the drive head.

[0009] According to the above scheme, the screw is provided with a mounting groove for assembling a sealing component. The sealing component includes a silicone gasket, a washer, and a sealing ring. The drive head passes through the sealing ring, washer, and silicone gasket and is then screwed into the screw hole for fixation. This design provides good water-proof performance.

[0010] According to the above scheme, a cutter shaft is fixed to the second end of the screw. The cutter shaft is coaxially arranged with the screw, and a square block is formed on the cutter shaft. A meat grinder is fixed on the square block, and the meat grinder is arranged corresponding to the discharge notch. This arrangement makes it easy to assemble the meat grinder, and after assembly, the meat grinder rotates coaxially with the screw.

[0011] According to the above scheme, the meat grinder is provided with a square hole for fixing to the square block, and the meat grinder is provided with a cross blade.

[0012] According to the above scheme, a screw limiting plate is formed on the outer wall of the first conical part to limit the stroke of the meat grinder. This design ensures that the screw will not shift back and forth when it is assembled inside the meat grinder.

[0013] According to the above scheme, the smaller end of the first conical part is connected to the first end of the central shaft, and the smaller end of the second conical part is connected to the second end of the central shaft. This arrangement makes pushing the ingredients smoother and prevents them from getting stuck.

[0014] According to the above scheme, the diameter of the central shaft is 10-12mm; the thickness of the spiral-shaped meat grinder is 1.5-2mm. This configuration, with a small diameter of the central shaft, increases the feeding space of the meat grinding chamber.

[0015] According to the above scheme, the diameter of the feed tube is 35-40mm, the width of the first pitch is 48-55mm, and the width of the second pitch is 21-26mm.

[0016] The beneficial effects of this utility model are: This invention features a spiral rib circumferentially formed on the inner wall of the meat grinding chamber, which works better with the screw to grind meat. A first pitch is formed between the spiral meat grinding blade and the outer wall of the central shaft. The first pitch is located below the feed tube, and its width is greater than the diameter of the feed tube. When food enters the meat grinding chamber through the feed tube, it falls within the first pitch, resulting in better feeding. The meat grinding cylinder and screw are made of food-grade 304 stainless steel, 316 stainless steel, or 420 stainless steel, which are durable and rust-free, and can be cleaned in a dishwasher for easy cleaning.

The meat grinding cylinder 1 and the screw 3 are made of food-grade 304 stainless steel, food-grade 316 stainless steel, or food-grade 420 stainless steel. This design features spiral ribs circumferentially on the inner wall of the grinding chamber, which work better with the screw 3 to grind meat. A first pitch 312 is formed between the spiral grinding blade 32 and the outer wall of the central shaft 31. The first pitch 312 is located below the feed pipe 11, and its width is greater than the diameter of the feed pipe 11. When food enters the grinding chamber through the feed pipe 11, it falls within the first pitch 312, resulting in better feeding. The grinding cylinder 1 and the screw 3 are made of food-grade 304 stainless steel, 316 stainless steel, or 420 stainless steel, which are durable, rust-free, and dishwasher-safe for easy cleaning.

[0021] Furthermore, a second pitch 313 is formed between the spiral meat grinder 32 and the outer wall of the central shaft 31. One end of the second pitch 313 is connected to the first pitch 312, and the width of the second pitch 313 is smaller than the width of the first pitch 312. The other end of the second pitch 313 forms a discharge notch 311, which is located on the outer wall of the second conical portion 36. This arrangement facilitates the feeding of ingredients into the first pitch 312 for smooth advancement, resulting in a faster advancement speed. Since the width of the second pitch 313 is smaller than the width of the first pitch 312, the speed of the ingredients slows down after they reach the second pitch 313. The ingredients then spread outward from the discharge notch 311 along the outer wall of the second conical portion 36 and are distributed into the various holes of the cutter disc.

[0022] The blade is fixed to the discharge port of the meat grinder 1.

[0023] Furthermore, the first end of the screw 3 is formed with a screw hole 39, and a drive head 7 is fixed inside the screw hole 39. A sealing assembly is provided between the drive head 7 and the screw 3. This arrangement facilitates the assembly of the drive head 7.

[0024] The depth of the screw hole 39 is preferably 12-13mm, which allows for a long tightening stroke and prevents it from coming loose after assembly.

[0025] Furthermore, the screw 3 is provided with a mounting groove 38 for assembling a sealing component. The sealing component includes a silicone gasket 4, a washer 5, and a sealing ring 6. The drive head 7 passes through the sealing ring 6, the washer 5, and the silicone gasket 4 and is then screwed into the screw hole 39 for secure fixing. This design ensures good water leakage prevention performance.

[0026] After assembly, the sealing ring 6 is fixed in the mounting groove 38, and the silicone pad 4 and gasket 5 are located inside the sealing ring 6.

[0027] Furthermore, a cutter shaft 33 is fixed to the second end of the screw 3. The cutter shaft 33 is coaxially arranged with the screw 3. A square block 35 is formed on the cutter shaft 33, and a meat grinder 8 is fixed on the square block 35. The meat grinder 8 is correspondingly arranged with the discharge notch 311. This arrangement makes it easy to assemble the meat grinder 8, and after assembly, the meat grinder 8 rotates coaxially with the screw 3.

[0028] Furthermore, the meat grinder 8 is provided with a square hole 81 for fixing to the square block 35, and the meat grinder 8 is provided with a cross blade 82. This configuration allows for more efficient meat grinding using the cross blade 82.

[0029] Furthermore, a screw limiting plate 37 is formed on the outer wall of the first conical portion 34 to limit the stroke of the meat grinder cylinder 1. This arrangement ensures that the screw 3 will not shift back and forth when it is assembled inside the meat grinder cylinder 1 and is in operation.

[0030] Furthermore, the smaller end of the first conical portion 34 is connected to the first end of the central shaft 31, and the smaller end of the second conical portion 36 is connected to the second end of the central shaft 31. This arrangement makes pushing the ingredients smoother and prevents them from getting stuck.

[0031] Furthermore, the diameter of the central shaft 31 is 10-12 mm; the thickness of the spiral meat grinder 32 is 1.5-2 mm. This configuration, with a small diameter of the central shaft 31, increases the feeding space of the meat grinding chamber.

[0032] Among them, the screw 3 is made of precision-cast stainless steel in one piece, which greatly reduces the weight of the product while ensuring structural strength, thus saving raw material consumption and costs.

[0033] Furthermore, the diameter of the feed tube 11 is 35-40mm, the width of the first pitch 312 is 48-55mm, and the width of the second pitch 313 is 21-26mm.
