Description

Technical Field

[0001] The present invention relates to the field of energy-saving food crushing, in particular to a food crushing device. Background Art

[0002] The food crushing device is divided into a fixed plate (lower grinding plate) and a rotating plate (upper grinding plate). The surface of the plate is mostly conical, toothed or grooved, and some are made of wear-resistant materials (such as ceramics and stainless steel). The grinding plate is fixed on the machine base, and the upper grinding plate is driven by the main shaft to rotate at high speed. When the food enters the gap between the two plates, it is crushed by shearing, crushing and impact. It is suitable for the crushing, grinding and refinement of a variety of food.

[0003] The spacing between the grinding discs in traditional crushing devices is mostly fixed (e.g., fixed by bolts or by replacing grinding discs of different specifications), and cannot be dynamically adjusted according to the hardness and particle size of the food. For example, when crushing soft ingredients (such as fruits and vegetables), a fixed small spacing will prevent the grinding area from being properly entered, causing the motor to idle at high speed, resulting in energy waste. When crushing hard ingredients (such as nuts), a fixed large spacing requires multiple crushing operations, which repeatedly consumes energy and is inefficient. Secondly, although some devices can adjust the spacing, they rely on manual disassembly of components (such as replacing gaskets and tightening bolts). A single adjustment is time-consuming, during which the equipment is shut down and wastes electricity. In addition, the lack of manual adjustment precision can easily lead to spacing that is too large or too small. The former will lead to incomplete crushing, while the latter will increase frictional heat generation and consume additional energy from the cooling system.

[0004] Traditional food crushing devices usually use simple funnel feeding or manual feeding, and cannot control the feed speed and flow rate. When food materials rush into the crushing area, it is easy to cause local overload, resulting in large fluctuations in motor load and even blockage of the equipment. When the feed is insufficient, the machine will idle, reducing the overall crushing efficiency. For example, when grinding nuts, uneven feed may cause some particles to be over-crushed and some to be insufficiently ground.

[0005] The feeding and crushing stages of traditional equipment are independent of each other, and the feeding speed cannot be adjusted in real time according to the crushing process. For example, when crushing high-hardness ingredients, if the feeding is too fast, it will lead to insufficient crushing and require secondary processing; if the feeding is too slow, the processing capacity of the crushing device will be wasted, reducing overall production efficiency. Secondly, the lack of stirring and drainage structure makes it easy for irregularly shaped ingredients to accumulate at the feeding port and even block the channel, requiring frequent shutdown for cleaning, affecting continuous operation.

[0006] Therefore, it is necessary to provide a food crushing device to solve the above problems. Summary of the Invention

[0010] Preferably, the adjustment assembly also includes four crushing discs, which are respectively fixedly connected to the side of the four T-shaped connecting plates away from the connecting rod. The bottom of the first positioning ring located above is fixedly connected to an electric cylinder, and four C-shaped material blocking plates are slidably connected between the four crushing discs.

[0011] Preferably, a feeding assembly is provided above the adjusting assembly, and the feeding assembly includes a discharge block, which is fixedly connected to the top of the positioning block, and a cross inclined groove is provided in the interior of the discharge block in a cross shape, and a working groove is provided in the interior of the discharge block, and a threaded rod is fixedly connected to the top of the power transmission rod.

[0012] Preferably, the feeding assembly also includes a positioning plate, which is fixedly connected to the bottom of the working trough, the top of the positioning plate is rotatably connected to a Y-shaped toggle rod, the middle part of the Y-shaped toggle rod is symmetrically rotatably connected to a connecting rod, the outer wall of the positioning plate is rotatably connected to a gear plate, the outer wall of the gear plate is symmetrically clamped with a power transmission plate through a pin, and the top of the threaded rod is slidably connected to a cross discharge plug.

[0013] Preferably, the second positioning ring is arranged above the limiting ring, and the output shaft of the electric cylinder is fixedly connected to the second positioning ring.

[0014] Preferably, the four crushing discs are distributed in an annular shape with equal distances, and there are gaps between the four crushing discs and the grinding disc on the inner wall of the positioning block.

[0015] Preferably, the top of the discharge block is configured to be funnel-shaped.

[0016] Preferably, the threaded rod is rotatably connected to the inside of the working groove, and the working groove is communicated with the cross inclined groove.

[0017] Preferably, the gear plate is arranged below the Y-shaped toggle rod, and the end of the connecting rod away from the Y-shaped toggle rod is rotatably connected to the outer wall of the power transmission plate.

[0018] Preferably, a blanking hole is provided on the top lower surface of the positioning block (21).

[0019] The food crushing device provided by the present invention has the following beneficial effects compared with the prior art:

[0020] The electric cylinder drives the second positioning ring to slide up and down, driving the connecting rod and the T-shaped connecting plate to move in conjunction, thereby realizing continuous adjustment of the distance between the crushing disc and the grinding disc. By dynamically adjusting the distance between the crushing disc and the grinding disc, the equipment can automatically match the power output according to the hardness of the food and the target particle size, avoiding the energy waste of "high-power idling" or "repeated crushing" of traditional fixed-spacing equipment, and realizing accurate utilization of energy from the source. The direct-drive structure and simple connecting rod mechanism reduce mechanical losses in power transmission, making the motor energy more efficiently converted into crushing kinetic energy, reducing the ineffective energy consumption caused by friction, idling, etc., thereby achieving the purpose of energy-saving motors in crushing devices.

[0021] The flexibly adjustable spacing design enables the equipment to handle both the fine grinding of hard ingredients such as nuts and beans, and the coarse crushing of soft ingredients such as fruits, vegetables, and cooked grains. One device covers multiple crushing needs, avoiding the energy consumption and cost waste of multiple devices.

[0022] Through non-contact electric adjustment, continuous change from coarse to fine crushed particles can be achieved without stopping the machine to replace parts, meeting the differentiated particle size requirements of different food processes (such as fillings, powders, and slurries), improving processing flexibility, and the tool-free electric adjustment method shortens the spacing adjustment time and reduces manual intervention errors. At the same time, it avoids equipment damage or safety hazards caused by component disassembly in traditional mechanical adjustment, achieving dual guarantees of efficiency and safety.

[0023] By connecting the power transmission rod of the crushing device with the feeding assembly and utilizing the meshing transmission of the threaded rod and the gear plate, the servo motor can drive the crushing disc while driving the feeding assembly without an additional power source. This design reduces the number of motor configurations and transmission components, lowering equipment costs and energy consumption, while simplifying the structure, reducing failure points, and improving equipment reliability.

[0024] Driven by a single power source, the feeding speed matches the crushing speed. The faster the crushing device runs, the higher the operating frequency of the feeding component, realizing "feeding on demand", avoiding power waste and incoordination problems in traditional equipment, and making efficient use of energy.

[0025] Through the linkage of the cross discharge plug, Y-shaped connecting rod and threaded rod, a compound action of up and down reciprocating motion and rotary stirring is achieved. This batch feeding method keeps the amount of food between the crushing disc and the grinding disc stable, avoids overload or idling, and improves crushing efficiency and uniformity.

[0026] The feeding rhythm is synchronized with the crushing process. When the crushing device processes high-hardness ingredients and the rotation speed decreases, the operating frequency of the feeding component also decreases, reducing the feed amount. Conversely, when processing soft ingredients, the feeding speed is increased to give full play to the processing capacity of the crushing device, ensure the efficiency and smoothness of the entire processing process, and reduce the energy consumption of the motor.

[0027] The setting of the cross discharge plug effectively prevents the accumulation of food on the top of the discharge block, ensures that it slides smoothly to the feeding channel, reduces the number of manual interventions and shutdowns for cleaning, and ensures the continuous operation of the equipment. The setting of the cross inclined groove evenly distributes the food to the four crushing areas, avoiding the uneven crushing problem caused by traditional single-side or single-point feeding. At the same time, the structure of the inclined groove guides the food to slide naturally, reduces residue, further improves feeding efficiency and cleaning convenience, and uniform feeding reduces single-point force, avoids the problem of increased energy consumption due to uneven electric force, and achieves the purpose of energy-saving motor.

Therefore, they should not be understood as limiting the present invention.

[0048] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0049] Implementation example Figures 1 to 7 、 Figure 13 and Figure 14 FIG. 1 shows a food crushing device provided by an embodiment of the present invention, comprising a crushing device housing 11 and a collecting box 12. The collecting box 12 is slidably connected to the bottom of the crushing device housing 11. An adjusting assembly is provided on the top of the crushing device housing 11.

[0050] The adjustment assembly includes a positioning block 21, a blanking hole is provided on the top lower surface of the positioning block 21, the positioning block 21 is fixedly connected to the top of the crushing device housing 11, a grinding disc is provided on the top inner wall of the positioning block 21, a servo motor 22 is fixedly installed on the bottom of the positioning block 21, a power transmission rod 210 is fixedly connected to the output shaft of the servo motor 22, two first positioning rings 23 are fixedly connected to the outer wall of the power transmission rod 210, a limiting ring 24 is fixedly connected to the middle of the power transmission rod 210, a second positioning ring 25 is slidably connected to the outer wall of the power transmission rod 210, and the second positioning ring 25 is provided on the limiting ring 24 Above it, it is used to limit the movement of the second positioning ring 25, and the outer walls of one of the first positioning ring 23 and the second positioning ring 25 are both annularly and equidistantly distributed and rotatably connected with four connecting rods 26, each four connecting rods 26 forming a group, and there are two groups of connecting rods 26. Every two connecting rods 26 are away from one end of the first positioning ring 23 and the second positioning ring 25 and are rotatably connected with a T-shaped connecting plate 27, and four T-shaped connecting plates 27 are provided.

[0051] The adjusting assembly also includes four crushing discs 28, which are respectively fixedly connected to the side of the four T-shaped connecting plates 27 away from the connecting rod 26. The four crushing discs 28 are distributed equidistantly in a ring, and there is a gap between the four crushing discs 28 and the grinding disc on the inner wall of the positioning block 21. The bottom of the first positioning ring 23 located above is fixedly connected to an electric cylinder 29, and four C-shaped material blocking plates 211 are slidably connected between the four crushing discs 28. The output shaft of the electric cylinder 29 is fixedly connected to the second positioning ring 25, so that the electric cylinder 29 can control the second positioning ring 25 to slide horizontally along the outer wall of the power transmission rod 210.

[0052] Working principle: After the staff starts the servo motor 22, the servo motor 22 will drive the power transmission rod 210 on its output shaft to rotate, and the power transmission rod 210 will drive the first positioning ring 23 and the second positioning ring 25 to rotate, and the first positioning ring 23 and the second positioning ring 25 will drive the four T-shaped connecting plates 27 to rotate synchronously through the connecting rod 26;

[0053] The four T-shaped connecting plates 27 rotate, driving the four crushing discs 28 to rotate synchronously, so that the four crushing discs 28 cooperate with the grinding discs on the inner wall of the positioning block 21 to crush the food.

[0054] Disc adjustment:

[0055] When food particles of different sizes need to be crushed, the staff can use the electric cylinder 29 to drive the second positioning ring 25 to slide along the outer wall of the power transmission rod 210;

[0056] When the electric cylinder 29 drives the second positioning ring 25 to rise along the outer wall of the power transmission rod 210, the second positioning ring 25 will drive the four connecting rods 26 of the outer wall to rise synchronously. In this process, the connection part between the connecting rod 26 and the first positioning ring 23 is a fixed point and only rotates but does not move. Therefore, the second positioning ring 25 moves up to pull the connecting rod 26 connected to it to move up, and pulls the connecting rod 26 connected to the first positioning ring 23 to rotate through the T-shaped connecting plate 27, so that the second positioning ring 25 and the connecting rod 26 connected to the first positioning ring 23 rotate synchronously from the bent state to the vertical state. At this time, the four connecting rods 26 will pull the four T-shaped connecting plates 27 to the power transmission rod 210, and the four connecting rods 26 on the outer wall of the first positioning ring 23 rotate in conjunction with the movement of the T-shaped connecting plate 27, thereby achieving the goal of pulling the four crushing discs 28 to move toward the power transmission rod 210 without moving up and down through the T-shaped connecting plate 27, so that the distance between the four crushing discs 28 and the grinding discs on the inner wall of the positioning block 21 is larger, and then in the same movement process, the four crushing discs 28 cooperate with the grinding discs on the inner wall of the positioning block 21 to crush the food particles, and the four crushing discs 28 will drive the four C-shaped blocking plates 211 to slide along the inside of the four crushing discs 28 to prevent the crushed food from remaining in the gaps between the four crushing discs 28;

[0057] On the contrary, when it is necessary to crush smaller food particles, the staff can use the electric cylinder 29 to drive the second positioning ring 25 to slide along the outer wall of the power transmission rod 210. When the electric cylinder 29 drives the second positioning ring 25 to descend along the outer wall of the power transmission rod 210, the second positioning ring 25 will drive the four connecting rods 26 of the outer wall to descend synchronously. At this time, the four connecting rods 26 will push the four T-shaped connecting plates 27 to move away from the center direction of the power transmission rod 210, while the four connecting rods 26 on the outer wall of the first positioning ring 23 are equipped with The T-shaped connecting plate 27 is rotated to push the four crushing discs 28 away from the power transmission rod 210 through the T-shaped connecting plate 27, so that the distance between the four crushing discs 28 and the grinding disc on the inner wall of the positioning block 21 is reduced, so that the four crushing discs 28 cooperate with the grinding disc on the inner wall of the positioning block 21 to crush the food particles into smaller particles. At the same time, the four crushing discs 28 drive the four C-shaped blocking plates 211 to slide into the inside of the four crushing discs 28, preventing the crushed food from remaining in the gaps between the four crushing discs 28;

[0058] Finally, after the crushing disc 28 cooperates with the grinding disc on the inner wall of the positioning block 21 to crush the food, the crushed food will fall into the inside of the collection box 12 along the gap between the crushing disc 28 and the grinding disc of the positioning block 21. When the collection box 12 inside the crushing device shell 11 is pulled out, the crushed food particles can be collected.

[0059] like Figures 8 to 11 、 Figure 12 and Figure 15 As shown, a feeding assembly is provided above the adjusting assembly, and the feeding assembly includes a discharge block 31, which is fixedly connected to the top of the positioning block 21. The interior of the discharge block 31 is provided with a cross-shaped inclined groove 32, and the top of the discharge block 31 is provided with a funnel shape, so that the food on the top of the discharge block 31 can be evenly fed through the cross-inclined groove 32. A working groove 33 is provided inside the discharge block 31, and the working groove 33 is connected to the cross-inclined groove 32. A threaded rod 34 is fixedly connected to the top of the power transmission rod 210.

[0060] The feeding assembly also includes a positioning plate 35, which is fixedly connected to the bottom of the working groove 33. The top of the positioning plate 35 is rotatably connected to a Y-shaped toggle rod 36, and the middle part of the Y-shaped toggle rod 36 is symmetrically rotatably connected to a connecting rod 37. The outer wall of the positioning plate 35 is rotatably connected to a gear disk 38, which is arranged below the Y-shaped toggle rod 36. The gear disk 38 is meshed with the threaded rod 34. The outer wall of the gear disk 38 is symmetrically connected to a power transmission disk 39 through a pin, and the two power transmission disks 39 are eccentrically arranged on the outer wall of the gear disk 38, and the connecting rod 37 is away from the Y-shaped toggle rod 36. One end is rotatably connected to the outer wall of the power transmission disk 39, so that the gear disk 38 drives the power transmission disk 39 to rotate, which will drive the Y-shaped toggle rod 36 to move. The top of the threaded rod 34 is slidably connected to the cross discharge plug 310, and the top of the threaded rod 34 is inserted with a vertical limit block. The cross discharge plug 310 is slidably connected to the vertical limit block of the threaded rod 34, and the threaded rod 34 is rotatably connected to the inside of the working groove 33, so that the cross discharge plug 310 can be driven to rotate during the rotation of the threaded rod 34, and the cross discharge plug 310 can slide on the top of the threaded rod 34.

[0061] Working principle: After the staff starts the servo motor 22, the servo motor 22 will drive the power transmission rod 210 on its output shaft to rotate, and the power transmission rod 210 will drive the top threaded rod 34 to rotate along the inside of the working groove 33;

[0062] Because the gear plate 38 is meshed with the threaded rod 34, the threaded rod 34 rotates, which in turn drives the gear plate 38 to rotate. Subsequently, the gear plate 38 drives the two eccentrically arranged power transmission plates 39 on both sides to rotate. The power transmission plates 39 drive the connecting rod 37 to move away from one end of the Y-shaped toggle rod 36 and to move in an arc around the center of the gear plate 38. The connecting rod 37 then drives the Y-shaped toggle rod 36 to reciprocate around the top of the positioning plate 35.

[0063] When the connecting rod 37 moves the Y-shaped toggle rod 36 upward, the end of the Y-shaped toggle rod 36 away from the positioning plate 35 will drive the cross discharge plug 310 to rise. Conversely, when the connecting rod 37 moves the Y-shaped toggle rod 36 downward, the end of the Y-shaped toggle rod 36 away from the positioning plate 35 will drive the cross discharge plug 310 to descend.

[0064] The cross discharge plug 310 drives the food to move synchronously. When descending, the cross discharge plug 310 allows the food to flow evenly into the crushing area through the cross inclined groove 32 in four directions; when rising, the cross discharge plug 310 temporarily seals the discharge channel to prevent excessive influx of food.

[0065] The threaded rod 34 drives the cross discharge plug 310 to rotate synchronously through the vertical limit block, and the Y-shaped driving rod 36 drives the cross discharge plug 310 to slide back and forth in the vertical direction along the top of the threaded rod 34;

[0066] After the staff puts the food on the top of the discharge block 31, the top of the discharge block 31 is set in a funnel shape, so that the food continues to move towards the cross discharge plug 310. During the descending process of the cross discharge plug 310, the cross discharge plug 310 will drive part of the food into the cross inclined groove 32, so that the food is evenly distributed in four directions and flows between the crushing disk 28 and the grinding disk on the inner wall of the positioning block 21, so as to facilitate the crushing of the food.

[0067] At the same time, when the cross discharge plug 310 is rising, the cross discharge plug 310 will temporarily seal the bottom of the discharge block 31 to prevent some food from flowing into the gap between the crushing disk 28 and the grinding disk of the positioning block 21 through the cross inclined groove 32;

[0068] When the threaded rod 34 drives the cross discharge plug 310 to rotate, the cross discharge plug 310 will stir the food on the top of the discharge block 31, thereby preventing the food from conflicting with each other during the feeding process and failing to slide smoothly to the bottom of the discharge block 31 for normal feeding.
