DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In one embodiment, see Figure 1-Figure 7 A meat grinder includes a processing tube 1, which is placed in a left-right direction, and a support leg 11 is arranged below the processing tube 1, so that the whole meat grinder can be directly placed on the ground for operation, and the processing tube 1 is a hollow tubular structure, the left end of the processing tube 1 is in an open state, and a feed nozzle 4 is arranged on the upper right side of the processing tube 1, and the feed nozzle 4 is a rectangular structure, and the upper and lower ends of the feed nozzle 4 penetrate and are connected with the inside of the processing tube 1, and meat can be put into the processing tube 1 through the feed nozzle 4 for mincing, and also includes a meat mincing mechanism 3 and a feeding mechanism 2; The meat grinder mechanism 3 includes a main shaft 5 which is rotatably connected to the inside of the processing tube 1 and is coaxially arranged with the processing tube 1. The main shaft 5 is also arranged in a left-right direction. The right side of the main shaft 5 is rotatably connected to the right end of the processing tube 1. A spiral feed blade 6 is arranged on the outside of the main shaft 5. After the spiral feed blade 6 extends to the left, the pitch gradually decreases, so that the meat is gradually squeezed as the spiral feed blade 6 moves to the left, which is convenient for subsequent meat crushing processing. In addition, a circle of annular cutters 19 are arranged on the outer edge of the right part of the spiral feed blade 6. The annular cutter 19 is just located below the feed nozzle 4. The annular cutter 19 corresponds to a central angle of 180 degrees. Therefore, when the annular cutter 19 rotates to the top, it falls from the feed nozzle 4. The meat strips will be blocked by the annular cutter 19. When the annular cutter 19 rotates downward, the meat strips will fall on the main shaft 5. At this time, the annular cutter 19 rotates upward again to cut the meat strips, so that the meat strips are cut into a fixed length to achieve a slicing effect. A porous plate 14 is provided at the left end of the processing tube 1, and a rotary cutter 18 is provided at the left end of the main shaft 5. The rotary cutter 18 can rotate synchronously with the main shaft 5. The rotating cutter 18 and the hole edges of the porous plate 14 interlaced with each other to achieve a shearing effect, so that the meat pieces are cut into particles and finally extruded through the holes of the porous plate 14 to achieve the effect of mincing meat. This part is similar to a conventional meat grinder. The feeding mechanism 2 includes a material guide trough 20 which is obliquely arranged at the end of the feeding nozzle 4 away from the processing tube 1. The material guide trough 20 is facing the upper right, and the cross-section of the material guide trough 20 is U-shaped. Therefore, when the meat strips are placed in the material guide trough 20, they will slide to the lower left along the material guide trough 20, and finally fall into the interior of the processing tube 1 through the feeding nozzle 4 to achieve the feeding effect.

[0022] In one case of the present embodiment, fixing blocks 15 are provided on both upper and lower sides of the left end of the processing tube 1, and a through hole 16 is provided in the middle of the fixing block 15. The through hole 16 penetrates and connects the locking bolts 13 arranged in left and right directions. The left end of the locking bolt 13 is fixedly connected to the upper and lower sides of the pressure ring 12. Therefore, during installation, the locking bolt 13 can be inserted into the through hole 16 from left to right, and the locking nut 17 is threadedly connected to the locking bolt 13 on the right side. At this time, the pressure ring 12 presses the porous plate 14 to the left end of the processing tube 1, thereby realizing the installation of the porous plate 14. If the parameters of the minced meat need to be changed, the pressure ring 12 can be loosened, and the porous plate 14 and the rotating cutter 18 can be replaced, thereby making the operation of the meat grinder more convenient.

[0023] In one case of this embodiment, a meat mincing drive motor 10 is arranged on the lower right side of the processing tube 1, and the output shaft of the meat mincing drive motor 10 is fixedly connected to the first pulley 9, the first pulley 9 is connected to the second pulley 7 through the belt 8, and the second pulley 7 is fixedly connected to the position where the main shaft 5 extends out of the processing tube 1. Therefore, the meat mincing drive motor 10 can realize the rotation driving process of the main shaft 5 through the effect of belt transmission.

[0024] In one case of the present embodiment, a clearance groove 35 is set in the lower middle part of the material guide groove 20, and a bearing seat 22 is set on the lower surface of the material guide groove 20, the bearing seat 22 is located on the front and rear sides of the clearance groove 35, the bearing seat 22 is rotatably connected to the feeding syringe 23 set in the front and rear directions, and a needle is set on the outside of the feeding syringe 23, so that the feeding syringe 23 can continuously insert the needle into the meat when rotating, thereby moving the meat block, thereby achieving the feeding effect, and a feeding drive motor 21 is set on the bearing seat 22 on the rear side, the feeding drive motor 21 drives the feeding syringe 23 to rotate, and an auxiliary clamping assembly 34 is set above the material guide groove 20, the auxiliary clamping assembly 34 can press the meat block on the feeding syringe 23 to facilitate the feeding syringe 23 to drive the meat block to move. There is a certain gap between the left end of the make way groove 35 and the feed syringe 23. A skin cutter 36 is set at the left end of the make way groove 35. The distance between the skin cutter 36 and the feed syringe 23 is just the thickness of the meat skin. Therefore, if peeling operation is required, the skin cutter 36 can be installed, and the skin of the meat block is placed on the guide groove 20 with the skin facing down. As the feed syringe 23 moves to the left, the meat block will contact the skin cutter 36, and the skin cutter 36 will separate the skin of the meat block to achieve the peeling process.

[0025] In one case of the present embodiment, the auxiliary clamping assembly 34 includes a hanging bracket 24 fixedly connected to the processing tube 1, the hanging bracket 24 is arranged on the left side of the material guide trough 20, the hanging bracket 24 is an L-shaped structure, the vertical plate of the hanging bracket 24 is fixed to the upper surface of the processing tube 1 on the left side of the material guide trough 20, the horizontal plate of the hanging bracket 24 extends to the right side, and a vertically arranged first hanging rod 27 is slidably connected to the right end of the horizontal plate of the hanging bracket 24, the lower end of the first hanging rod 27 is rotatably connected to the right side of the upper surface of the guide pressure plate 25, a first fixing ring 31 is arranged in the middle of the first hanging rod 27, a first buffer spring 32 is arranged between the first fixing ring 31 and the hanging bracket 24, the first buffer spring 32 is sleeved on the outside of the first hanging rod 27, and the upper end of the first buffer spring 32 is fixedly connected to the hanging bracket 24, and the lower end of the first buffer spring 32 is connected to the first fixing ring 31. The ring 31 is fixedly connected, so that the first buffer spring 32 pulls up the first suspension rod 27, and a vertically arranged second suspension rod 28 is slidably connected on the left side of the suspension frame 24, and the upper end of the second suspension rod 28 is fixedly connected to the limit plate 33. The limit plate 33 is set to prevent the second suspension rod 28 from falling, and the lower end of the second suspension rod 28 is rotationally connected to the upper end of the support rod 26, and the lower end of the support rod 26 is rotationally connected to the left side of the upper surface of the guide pressure plate 25, and a second fixed ring 29 is set in the middle of the second suspension rod 28, and a second buffer spring 30 is set on the second fixed ring 29, and the second buffer spring 30 is sleeved on the outside of the second suspension rod 28, and the second buffer spring 30 is shorter than the first buffer spring 32, so the second buffer spring 30 will only contact the suspension frame 24 when the second suspension rod 28 moves to a high place, thereby achieving the extrusion effect.

[0026] During the implementation of this embodiment, the meat grinder is stably placed on the ground, and a porous plate 14 and a rotary cutter 18 of a suitable size are selected for installation, and the feed drive motor 21 and the meat grinder drive motor 10 are started. At this time, the entire meat grinder is ready.

[0027] The operator holds the meat block that needs to be minced, places the skin side of the meat block on the guide trough 20, loosens the meat block, and the meat block slides to the lower left along the guide trough 20 under the action of gravity. At this time, the guide pressure plate 25 is inclined to the upper right, and the upper left side of the meat block will contact the lower surface of the guide pressure plate 25. As the meat block continues to fall, the guide pressure plate 25 will adaptively deflect and move upward, so that the meat block will continue to be close to the inside of the guide trough 20. When the meat block is behind the feed syringe 23, the needle of the feed syringe 23 will be inserted into the meat block, and the meat block will be driven downward by the feed syringe 23. After the lower surface of the meat block contacts the skin cutter 36, the skin of the meat block is separated, and after the separation is completed, it will fall into the inside of the processing tube 1 through the feed nozzle 4.

[0028] After the long piece of meat falls into the processing tube 1, it will fall on the main shaft 5. At this time, if the rotary cutter 18 contacts the meat strip, the meat strip will be cut, and the cut meat strip will move to the left with the spiral feeding blade 6. If the rotary cutter 18 rotates upward, the meat strip will be blocked by the rotary cutter 18 when it falls again. Therefore, the meat strip will not fall onto the main shaft 5 until the rotary cutter 18 rotates downward, thereby realizing the intermittent cutting of the long piece of meat. After the meat strip moves to the left, it will be chopped by the cooperation of the rotary cutter 18 and the porous plate 14, and the spiral feeding blade 6 continues to push the meat strip to the left, so that the chopped minced meat is squeezed out through the porous plate 14, thereby realizing the minced meat processing.

[0029] The present invention is applicable to a meat grinder. By arranging an annular cutter 19 on the outer edge of a spiral feed blade 6, the spiral feed blade 6 can not only squeeze the meat block but also cut the meat block into sections. Therefore, the operator does not need to perform additional cutting before mincing the meat, which reduces the processing steps and improves the processing efficiency of the entire meat mincing operation.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
