Description

Technical Field

[0001] This invention relates to the field of meat mixing and grinding equipment, and more particularly to a meat mixing and grinding machine. Background Technology

[0002] The applicant's prior patent application, publication number CN114392813A, describes an integrated meat mixing and grinding machine. In this machine, chunks of meat are first mixed with seasonings before grinding, allowing for better flavor absorption and a superior texture. This technology has been well-received in restaurants, canteens, and food factories where large quantities of minced meat are needed.

[0003] However, in this patented technical solution, the mixing bin and the meat grinder are arranged in parallel, and the receiving hopper of the meat grinder is located at the bottom middle of the mixing bin. This can easily cause some meat pieces to remain at both ends of the mixing bin or hang on the middle mixing paddle, resulting in difficulty in discharging and serious problem of residual material. It often requires manual cleaning of the residual meat pieces.

[0004] Therefore, it is necessary to develop a new meat mixing machine to solve the problems in the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a meat mixing machine with a reasonably set discharge port position, which can improve the situation of meat residue in the mixing chamber.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This invention discloses a meat grinding and mixing machine, comprising a frame, a mixing reduction motor, a mixing shaft, a shaft end docking assembly, and a meat grinder. The upper part of the frame is provided with an upward-opening mixing chamber, the mixing chamber having a U-shaped cross-section. The mixing shaft is horizontally disposed at the bottom of the mixing chamber, one end of which is detachably connected to the mixing output shaft of the mixing reduction motor, and the other end is detachably connected to the end side wall via the shaft end docking assembly. The mixing chamber has a discharge port at the bottom of the end near the mixing reduction motor, and the inlet of the meat grinder is located below the discharge port. The axis of the meat grinder is perpendicular to the mixing shaft, and the discharge end of the meat grinder protrudes outside the frame housing.

[0008] Furthermore, the output end of the mixing output shaft is a flat head, and the mixing shaft is coaxially connected to the flat head through the flat head sleeve hole.

[0009] Furthermore, the shaft end docking assembly includes a bushing, a wear-resistant sleeve, a top core, and a top pad. The bushing is coaxially arranged with the mixing output shaft and detachably connected to the end side wall of the mixing chamber. The wear-resistant sleeve is coaxially assembled at the inner end of the bushing, and the end of the mixing shaft away from the flat head can be rotatably inserted into the wear-resistant sleeve. The outer end of the bushing is coaxially configured with a threaded hole section, and the top core is threadedly connected to the threaded hole section. The inner end face of the top core abuts against the shaft end face of the mixing shaft through the top pad.

[0010] Furthermore, the shaft end docking assembly also includes a quick-connect screw; a flange plate is provided on the outer wall of the bushing, and the flange plate is in the shape of a long strip plate; a quick-connect screw seat is provided on the frame around the bushing mounting hole, and two quick-connect screw seats are symmetrically arranged along the axis of the bushing mounting hole; the quick-connect screw seat is an L-shaped plate structure, and the quick-connect screw is threadedly connected to the top plate of the quick-connect screw seat, and the inner end of the quick-connect screw can be screwed into the locking hole on the flange plate; a rotating handle is provided at the tail of the quick-connect screw.

[0011] Furthermore, the shaft end docking assembly also includes a set screw, and the outer wall of the bushing is radially provided with a threaded hole. The set screw is connected in the threaded hole and its inner end can be pressed against the set core.

[0012] Furthermore, the mixing shaft is provided with multiple mixing blades, each mixing blade including an outer inclined blade and a connecting rod, the root of which is inserted into a radial hole on the mixing shaft and welded together.

[0013] Furthermore, the meat grinder includes a meat grinding reduction motor and a meat grinding mechanism. The meat grinding mechanism includes a spiral shaft, a housing, a cross blade, a mesh plate, an outer cover, and a top pin. The spiral shaft is horizontally arranged in a U-shaped housing below the discharge port. The output end of the meat grinding output shaft of the meat grinding reduction motor is configured with a square head, which is inserted into a square hole at the inner end of the spiral shaft. The housing is coaxially mounted on the outer end of the spiral shaft, and the inner end of the housing is mounted on the frame by flange bolts. The cross blade, mesh plate, outer cover, and top pin are connected to the outer ends of the spiral shaft and the housing.

[0014] Furthermore, it also includes a baffle, which is fastened to the top opening of the mixing chamber. The baffle includes a side end plate and railings, and a plurality of railings are arranged in a convex arc shape and connected between two side end plates. The rear end of the side end plate is connected to a pivot seat through a short pivot, and the pivot seat is mounted on the top plate of the frame.

[0015] Furthermore, a pull tab is attached to the rear of the outer side end plate by a screw. The pull tab can rotate around the screw. The long strip-shaped pull tab has a long strip-shaped stop pin groove. A stop pin platform is provided on the side wall of the frame. A stop pin is threaded onto the stop pin platform. The stop pin is guided in the stop pin groove. A parking groove is provided at the bottom end of the stop pin groove.

[0016] Furthermore, a sensing block is provided at the front end of the side plate of the cover rail, and a sensing switch is provided at the corresponding position of the sensing block when the cover rail is in the locked state. The sensing switch is electrically connected to the controller of the equipment.

[0017] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0018] This invention discloses a meat grinding and mixing machine. By placing the discharge port at one end of the mixing chamber, the deflection direction of the mixing blades on the mixing shaft can be uniformly set. During discharge, the material is continuously pushed towards one end, reducing meat residue. Through the vertically aligned mixing shaft and meat grinder, the mixing blades on the mixing shaft push the material along the feeding direction of the meat grinder, ensuring consistency between the two directions. This increases the grinding speed of meat pieces and improves work efficiency. This invention's meat grinding and mixing machine, with its rationally positioned discharge port, effectively reduces meat residue in the mixing chamber.

[0019] Furthermore, the flat-head sleeve hole and flat-head mating connection facilitates quick connection between the mixing output shaft and the mixing shaft, and can transmit sufficiently large torque. The method of using a bushing fitted onto the end of the mixing shaft improves support strength and prevents deformation under stress. The top core axially limits the mixing shaft, balancing the axial reaction force generated during forward or reverse rotation and preventing axial movement. The wear-resistant sleeve and top gasket reduce wear and noise. The flange plate, quick-release seat, and quick-release screw lock the circumferential position of the bushing, preventing it from rotating with the mixing shaft. The rotary handle at the end of the quick-release screw facilitates operation. The top screw on the bushing locks the top core, preventing it from loosening due to mixing vibration. The method of inserting and then welding at the root of the mixing blade improves the connection between the mixing blade and the mixing shaft, preventing breakage at the blade root. By disassembling the outer cover and pulling the top pin, the cross blade, mesh plate, and spiral shaft can all be removed from below the discharge port for easy maintenance and cleaning. The baffle prevents meat chunks from being pushed out by the mixing paddle during rapid agitation. The pull plate and stop pin keep the baffle open, facilitating the addition of meat chunks and seasonings. The sensor block and sensor switch provide feedback to the equipment controller that the baffle is closed. Electrical interlocking prevents the mixing and grinding motors from starting when the baffle is open, ensuring operator safety. Attached Figure Description

Detailed Implementation

[0031] The core of this invention is to provide a meat mixing machine with a reasonably set discharge port position, which can improve the situation of meat residue in the mixing chamber.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0034] Refer to the attached diagram. Figure 1 This is a three-dimensional structural diagram of the meat mixing and grinding machine of the present invention; Figure 2 This is a schematic diagram of the main structure of the meat mixing and grinding machine of the present invention; Figure 3 This is a schematic diagram of the left side of the meat mixing and grinding machine of the present invention; Figure 4This is a schematic diagram of the right side of the meat mixing and grinding machine of the present invention; Figure 5 This is a top view schematic diagram of the meat mixing and grinding machine of the present invention; Figure 6 for Figure 2 Schematic diagram of the AA section; Figure 7 for Figure 3 Schematic diagram of the BB section; Figure 8 for Figure 1 A magnified schematic diagram of a portion of the central I section; Figure 9 for Figure 7 A magnified schematic diagram of the J-section.

[0035] In one specific implementation, such as Figures 1-9 As shown, a meat grinding and mixing machine includes a frame 1, a mixing and reducing motor 2, a mixing and stirring shaft 3, a shaft end docking assembly 5, and a meat grinder. The upper part of the frame 1 has an upward-opening mixing chamber 4, which has a U-shaped cross-section and a rounded bottom. The mixing and stirring shaft 3 is horizontally positioned at the bottom of the mixing chamber 4 and along its length. One end of the mixing and stirring shaft 3 is detachably connected to the mixing output shaft 201 of the mixing and reducing motor 2, and the other end is detachably connected to the end side wall via the shaft end docking assembly 5. The mixing chamber 4 has a discharge port 401 at its bottom end near the mixing and reducing motor 2, and the length of the discharge port 401 is along the axis of the meat grinder. The inlet of the meat grinder is located below the discharge port 401, and the axis of the meat grinder is perpendicular to the mixing and stirring shaft 3. The discharge end of the meat grinder protrudes outside the frame 1 housing. The parts of the meat mixing and grinding machine of this invention that come into contact with materials are all made of food-grade stainless steel.

[0036] By placing the discharge port 401 at one end of the bottom of the mixing chamber 4, the tilt direction of the stirring blades on the mixing shaft 3 can be uniformly set, and the material is continuously pushed towards one end during discharge, reducing the residue of meat chunks. Through the mixing shaft 3 and the meat grinder, which are vertically aligned, the pushing direction of the stirring blades on the mixing shaft 3 is along the feeding direction of the meat grinder during grinding, ensuring that both directions are consistent. This increases the grinding speed of meat chunks and improves work efficiency. The meat mixing and grinding machine of this invention, with its rationally designed discharge port position, can improve the situation of meat chunk residue in the mixing chamber.

[0037] In one specific embodiment of the present invention, such as Figure 7 As shown, the output end of the mixing output shaft 201 is a flat head, and the mixing shaft 3 is coaxially connected to the flat head through the flat head sleeve hole. In fact, the shaft end of the mixing shaft 3 has the same diameter as the mixing output shaft 201 and is provided with a flat groove. This section is fitted with a section of stainless steel sleeve and welded firmly.

[0038] Obviously, the mixing output shaft 201 and the mixing stirring shaft 3 can also be connected by a cross shaft head or a square shaft head. Similar simple structural modifications all fall within the protection scope of this invention.

[0039] The flat head sleeve hole and the flat head are connected to facilitate quick connection between the mixing output shaft 201 and the mixing shaft 3, and can transmit a sufficiently large torque.

[0040] In one specific embodiment of the present invention, such as Figure 1 and Figures 7-9 As shown, the shaft end docking assembly 5 includes a bushing 501, a wear-resistant sleeve 502, a top core 503, and a top pad 504. The bushing 501 is coaxially arranged with the mixing output shaft 201 and detachably connected to the end side wall of the mixing chamber 4. The wear-resistant sleeve 502 is coaxially assembled on the inner end of the bushing 501, and the end of the mixing shaft 3 away from the flat head can be rotatably inserted into the wear-resistant sleeve 502. The outer end of the bushing 501 is coaxially configured with a threaded hole section, and the top core 503 is threadedly connected to the threaded hole section. The inner end face of the top core 503 abuts against the shaft end face of the mixing shaft 3 through the top pad 504. Both the wear-resistant sleeve 502 and the top pad 504 are made of smooth polytetrafluoroethylene plastic.

[0041] Specifically, the end of the top core 503 is provided with a slotted or Phillips head slot, which makes it easy to rotate and adjust using a screwdriver.

[0042] Specifically, such as Figure 1 and Figures 7-9 As shown, the shaft end docking assembly 5 also includes a quick-release screw 506. A flange plate 5011, which is elongated, is provided on the outer wall of the bushing 501. A quick-release screw seat 104 is provided around the mounting hole of the bushing 501 on the frame 1. Two quick-release screw seats 104 are symmetrically arranged along the axis of the mounting hole of the bushing 501. The quick-release screw seat 104 has an L-shaped plate structure. The root of the vertical plate of the quick-release screw seat 104 is welded to the wall panel of the frame 1. The quick-release screw 506 is threaded onto the top plate of the quick-release screw seat 104. The inner end of the quick-release screw 506 can be screwed into and locked in the locking hole on the flange plate 5011. A rotating handle is provided at the tail of the quick-release screw 506.

[0043] Specifically, such as Figure 1 and Figures 7-9 As shown, the shaft end mating assembly 5 also includes a set screw 505. A threaded hole is radially provided on the outer wall of the bushing 501. The set screw 505 is connected in the threaded hole and its inner end can be pressed against the core 503. There are two set screws 505, which are symmetrically arranged along the axis of the bushing 501.

[0044] The use of a bushing 501 fitted onto the end of the mixing shaft 3 improves support strength and prevents deformation under stress. The top core 503 axially limits the mixing shaft 3, balancing the axial reaction force generated during forward or reverse rotation and preventing axial movement. The wear-resistant sleeve 502 and top pad 504 reduce wear and noise. The flange plate 5011, quick-release seat 104, and quick-release screw 506 lock the circumferential position of the bushing 501, preventing it from rotating with the mixing shaft 3. The handle at the end of the quick-release screw 506 facilitates operation. The top screw 505 on the bushing 501 locks the top core 503, preventing it from loosening due to mixing vibration.

[0045] In one specific embodiment of the present invention, such as Figure 7 and Figure 9 As shown, the mixing shaft 3 is equipped with multiple mixing blades 301. Each mixing blade 301 includes an inclined blade at its outer end and a connecting rod for connection. The root of the connecting rod is inserted into a radial hole on the mixing shaft 3 and welded together. The radial hole is a through hole, and the narrowed shaft end of the connecting rod is fully inserted into the radial hole. The root is corner welded, and the other end is welded flat and ground smooth.

[0046] By inserting and then welding the stirring paddle 301 at its root, the connection between the stirring paddle 301 and the mixing shaft 3 can be improved, thus avoiding the possibility of the stirring paddle 301 breaking at its root.

[0047] In one specific embodiment of the present invention, such as Figures 1-6 As shown, the meat grinder includes a meat grinding reduction motor 6 and a meat grinding mechanism 7. The meat grinding mechanism 7 includes a spiral shaft, a housing 701, a cross blade 702, a mesh plate 703, an outer cover 704, and a top pin 705. The spiral shaft is horizontally arranged in a U-shaped housing below the discharge port 401. The output end of the meat grinding output shaft 601 of the meat grinding reduction motor 6 is set with a square head, which is inserted into a square hole at the inner end of the spiral shaft. The housing 701 is coaxially mounted on the outer end of the spiral shaft, and the inner end of the housing 701 is mounted on the frame 1 by flange bolts. The cross blade 702, the mesh plate 703, the outer cover 704, and the top pin 705 are connected to the outer end of the spiral shaft and the housing 701. The inner end of the top pin 705 is threaded into a threaded hole on the outer end face of the spiral shaft. The cross blade 702 has a square hole in the middle and is sleeved on the square shaft section of the top pin 705 and rotates synchronously with the spiral shaft. The perforated plate 703 is embedded in the outer end of the outer shell 701, and the inner hole of the perforated plate 703 is fitted with the round shaft section of the top pin 705. The outer cover 704 is threaded onto the outer wall thread of the outer shell 701 and axially positions the perforated plate 703.

[0048] By removing the outer cover 704 and pulling the top pin 705, the cross blade 702, the mesh plate 703, and the spiral shaft can all be removed from below the discharge port 401 for easy maintenance and cleaning.

[0049] In one specific embodiment of the present invention, such as Figures 1-7 As shown, the meat mixing machine of the present invention also includes a baffle 8, which is fastened to the top opening of the mixing chamber 4. The baffle 8 includes side end plates and railings, with multiple railings arranged in a convex arc shape and connected between two side end plates. The rear end of the side end plates is connected to a shaft seat 103 via a short rotating shaft, and the shaft seat 103 is mounted on the top plate of the frame 1.

[0050] Specifically, such as Figure 1 and Figure 4 As shown, a pull tab 803 is attached to the rear of the outer side plate via screws. The pull tab 803 can rotate around the screws. A long, narrow groove 8021 for a stop pin is formed on the pull tab 803. A stop pin platform 105 is provided on the side wall of the frame 1, and a stop pin is threaded onto the stop pin platform 105. The stop pin is guided within the stop pin groove 8021, and a stopping groove is provided at the bottom end of the stop pin groove 8021. When the cover 8 is fully open, the stop pin enters the stopping groove, maintaining the open angle of the cover 8.

[0051] Specifically, such as Figure 1 and Figure 5 As shown, a sensing block 801 is welded to the front end of the side plate of the cover rail 8. A sensing switch is provided at the corresponding position of the sensing block 801 when the cover rail 8 is in the closed state. The sensing switch is electrically connected to the controller of the equipment.

[0052] Obviously, the inductive switch can be a proximity switch or an electromagnetic induction switch, which can send a signal of the cover 8 being closed to the device controller.

[0053] The baffle 8 prevents meat chunks from being pushed out by the mixing paddle 301 during rapid agitation. The pull plate 803 and the stop pin keep the baffle 8 in the open position, facilitating the addition of meat chunks and seasonings. The sensor block 801 and the sensor switch provide feedback to the equipment controller that the baffle 8 is closed. Electrical interlocking prevents the mixing motor 2 and the meat grinder motor 6 from starting when the baffle 8 is open, ensuring operator safety.

[0054] When the meat mixing and grinding machine of this invention is working, the meat is cut into roughly uniform pieces, and an appropriate amount of seasonings are prepared. The operator manually opens the cover 8, allowing the stop pin to enter the parking groove of the pull plate 803, keeping the cover 8 in the open state. The meat pieces and seasonings are put into the mixing chamber 4, and the cover 8 is closed. The mixing start button on the control panel 9 is pressed, and the mixing reduction motor 2 starts, driving the mixing stirring shaft 3 to rotate. The stirring paddle 301 stirs and mixes the meat pieces. According to the parameter settings of the controller, the mixing reduction motor 2 rotates forward and reverse at specified intervals, driving the stirring paddle 301 to stir the material back and forth in both directions, making the mixing more uniform. After the set mixing time is reached, the meat grinding start button on the control panel 9 is pressed, and the meat grinding reduction motor 6 starts simultaneously, driving the spiral shaft to rotate. The mixing stirring shaft 3 rotates counterclockwise, continuously conveying the meat pieces towards the discharge port 401. The meat pieces from the discharge port 401 descend into the meat grinding mechanism 7. The spiral conveying section of the spiral shaft continuously conveys the squeezed and mixed meat chunks outwards, and the cross blade 702 cuts the meat strips that pass through the mesh plate 703 and grinds them into minced meat.

[0055] When cleaning the equipment, turn off the emergency stop button on the electrical control panel 9, release the quick-release screw 506, hold the knurled section of the bushing 501 and rotate the bushing 501 to disengage the flange plate 5011 from the quick-release screw seat 104, and remove the bushing 501 outwards. Open the cover 8 to remove the mixing shaft 3 from the mixing chamber 4. Remove the outer cover 704 from the outer end of the outer casing 701, and pull the top pin 705 to remove the cross blade 702, the mesh plate 703, and the spiral shaft from below the discharge port 401. At this time, there are no obstructions in the mixing chamber 4 and the inner cavity of the outer casing 701, making it easy to rinse and wipe for maintenance.

[0056] This invention relates to a meat grinding and mixing machine. By positioning the discharge port 401 at one end of the bottom of the mixing chamber 4, the tilt direction of the mixing blades on the mixing shaft 3 can be uniformly set. During discharge, the material is continuously pushed towards one end, reducing meat residue. Through the vertically aligned mixing shaft 3 and the meat grinder, the mixing blades on the mixing shaft 3 push the material along the feeding direction of the meat grinder, ensuring consistency between the two directions and increasing the grinding speed of meat pieces, thus improving work efficiency. The invention's meat grinding and mixing machine, with its rationally positioned discharge port, improves the meat residue situation in the mixing chamber. Furthermore, the mating connection between the flat head sleeve hole and the flat head facilitates quick connection between the mixing output shaft 201 and the mixing shaft 3, and enables the transmission of sufficiently large torque. The use of a bushing 501 fitted onto the end of the mixing shaft 3 improves support strength and prevents deformation under stress. The top core 503 axially limits the mixing shaft 3, balancing the axial reaction force generated during forward or reverse rotation and preventing axial movement. The wear-resistant sleeve 502 and top pad 504 reduce wear and noise. The flange plate 5011, quick-release seat 104, and quick-release screw 506 lock the circumferential position of the bushing 501, preventing it from rotating with the mixing shaft 3. The handle at the end of the quick-release screw 506 facilitates operation. The top screw 505 on the bushing 501 locks the top core 503, preventing it from loosening due to mixing vibration. The connection between the mixing paddle 301 and the mixing shaft 3 is improved by inserting and then welding at the root, preventing breakage at the root of the mixing paddle 301. By disassembling the outer cover 704 and pulling the top pin 705, the cross blade 702, mesh plate 703, and spiral shaft can all be removed from below the discharge port 401 for easy maintenance and cleaning. The baffle 8 prevents meat chunks from being pushed out by the mixing paddle 301 during rapid agitation. The pull plate 803 and the stop pin keep the baffle 8 in the open position, facilitating the addition of meat chunks and seasonings. The sensor block 801 and the sensor switch provide feedback to the equipment controller that the baffle 8 is closed. Electrical interlocking prevents the mixing reduction motor 2 and the meat grinding reduction motor 6 from starting when the baffle 8 is open, ensuring operator safety.
