[0019] In the embodiment of the present invention, the frame has the function of accommodating parts and supporting, and the rigidity of the frame affects the cutting accuracy and production efficiency of the vegetable cutter. Dynamic rigidity determines the anti-seismic ability of the frame in the working state. Improving the control of natural frequency, increasing damping and static rigidity can improve the anti-seismic ability of the frame. Strength determines the working performance of the frame. The strength of the frame is affected by the combined static and dynamic effects. In order to make the frame have better strength and rigidity, this design will cast the base and the chassis into one. This structure has the advantages of high stability, simple structure, reasonable layout and strong anti-seismic ability.

[0020] In the embodiment of the present invention, the casting frame material includes but is not limited to: cast iron, forged carbon steel, cast aluminum alloy, etc. Cast iron has the advantages of small linear shrinkage, good fluidity, small volume shrinkage, and can cast complex castings; forged carbon steel is suitable for casting larger frames, and its strength is higher than cast iron, and its elastic modulus is large; cast aluminum alloy has higher toughness and strength after heat treatment strengthening, and also has the advantages of light weight and low density. According to the design requirements of the vegetable cutter of the present invention, a cast iron material with better shock resistance, low price and strong shock absorption capacity will be selected. Since the structure of the vegetable cutter is relatively complex, welding is selected for casting.

[0021] In the embodiment of the present invention, the working principle of the vegetable cutter is to use the moving cutter to apply shear force to the vegetables, so that the cutter and the vegetables move relative to each other, so as to realize the process of cutting vegetables into segments, shreds, slices and dices (blocks). To complete the cutting operation, the vegetable cutter must have a complete set of mechanical structures, mainly including: cutting mechanism, braking mechanism, material conveying mechanism and external support mechanism. Among them, the cutting mechanism provides shear force for the material to be cut to break it, the braking mechanism is used to adjust the working efficiency of the vegetable cutter, the material conveying mechanism provides the conditions for relative movement between the material to be cut and the cutting mechanism, and the external support positioning mechanism provides support for other structures. The technical indicators of the vegetable cutter are shown in Table 1.

[0022] Table 1 Technical indicators of vegetable cutter

[0023] Traditional vegetable cutters can only cut a single type of vegetables and are limited in the types of vegetables they can process. In addition, they cannot continuously feed and cut during the processing, which affects the efficiency of food processing.

[0024] The multifunctional vegetable cutter provided in an embodiment of the present invention comprises a frame, wherein the frame comprises a head and a body; a double feed inlet arranged on the head; a cutting mechanism arranged on the body, and a discharge port connected to the cutting mechanism; and a transmission mechanism arranged between the head and the body; the double feed inlets are used to receive various types of vegetables; the transmission mechanism is used to transmit the various types of vegetables to the cutting mechanism; the cutting mechanism is used to cut the various types of vegetables, and output the vegetable processing semi-finished products from the discharge port after cutting. Various types of vegetables can be processed by arranging at least one feed inlet and a conveyor belt and a cutting mechanism for cutting various types of vegetables. At least one feed inlet and a conveyor belt are arranged on the same head. Compared with the traditional multi-head structure, the structure of the present invention is more reasonable, the volume of the vegetable cutter is reduced, and continuous operation can be achieved through the transmission mechanism.

[0025] Based on any of the above embodiments,

[0026] At least one feed inlet includes a feed hopper and a circular feed inlet, wherein the feed hopper and the circular feed inlet are located above the cutting mechanism; Irregular or spherical root vegetables, stem vegetables, cabbage leaf vegetables, bulb leaf vegetables, eggplants and gourds are received through the feed hopper. After the feed opening of the feed hopper is opened, the vegetables are cut into shreds, slices, dices (blocks) by the comb-shaped blade slicing knife group, the arc-shaped slicing knife group and the mesh dicing knife group under the combined action of gravity, pressure of the outer cover and the knife disc on the vegetables and shear force of the blade on the vegetables, and then fall out of the discharge port under the action of gravity; Regular (quasi-cylindrical) root vegetables and legume vegetables are received through the circular inlet, and after the circular inlet is opened, the vegetables are cut into shreds, slices, dices (blocks) by the comb-shaped blade slicing knife group, the arc-shaped slicing knife group, and the mesh dicing knife group under the combined action of manual thrust, pressure on the vegetables by the knife disc, and shear force on the vegetables by the blade, and fall out of the outlet under the action of gravity.

[0027] For example, irregular or spherical vegetables such as potatoes, tomatoes and cabbages can be directly placed in the feed hopper for cutting; regular (cylindrical) vegetables such as cucumbers, carrots and yams can be directly placed in the circular feed port for cutting, which can improve cutting efficiency.

[0028] The conveyor belt is used to receive common leafy vegetables, spicy leafy vegetables, cauliflowers and legumes, and convey them to the three-leaf arc-shaped convex blade group of the cutting mechanism. Under the shear force of the blades on the vegetables, the vegetables are cut into shreds or segments and fall out of the discharge port under the action of gravity.

[0029] For example, long or soft vegetables such as celery, onions and day lilies can be cut directly onto the conveyor belt.

[0030] The vegetable cutter achieves the purpose of processing different vegetables by switching different knives. The multifunctional vegetable cutter provided by the present invention includes four blades for processing and processing different kinds of vegetables, covering most vegetable varieties on the market. The cutting mechanism includes: The three-leaf arc-shaped convex blade knife set is used for slicing or cutting leafy vegetables, spicy leafy vegetables, cauliflowers and legumes; the structure of the three-leaf arc-shaped convex blade knife set is as follows Figure 3 As shown, it can be used to cut long or soft common leafy vegetables such as celery, onion and day lily, spicy leafy vegetables, cauliflower and legume vegetables into strips or sections.

[0031] The comb-shaped blade slicing knife set is used for slicing root vegetables, stem vegetables, cabbage leafy vegetables, bulbous leafy vegetables and fruit vegetables; the structure of the comb-shaped blade slicing knife set is as follows Figure 4 As shown, it can be used to process root vegetables such as potatoes and cabbages, stem vegetables, head leafy vegetables, bulb leafy vegetables and fruit vegetables for shredding.

[0032] The arc-shaped blade group is used for slicing root vegetables, stem vegetables, cabbage leafy vegetables, bulbous leafy vegetables and fruit vegetables; the structure of the arc-shaped blade group is as follows Figure 5 As shown, it can be used to process slices of root vegetables such as cucumbers and yams, stem vegetables, head leafy vegetables, bulb leafy vegetables and fruit vegetables.

[0033] The mesh dicing knife set is used to dice the root vegetables, stem vegetables, cabbage vegetables, bulbous vegetables and fruit vegetables. Figure 6 As shown, it can be used to dice (block) root vegetables such as carrots and onions, stem vegetables, head leafy vegetables, bulb leafy vegetables and fruit vegetables.

[0034] By selecting and using four types of knives, namely, three-leaf arc-shaped knives, comb-shaped blade wire knives, arc-shaped slice knives, and mesh dicing knives, the cutting requirements of most vegetable varieties on the market can be met, such as segmenting, shredding, slicing, and dicing (blocking), and a variety of vegetable processing semi-finished products can be provided, achieving the design purpose of "one machine for multiple uses". First, vegetables are divided into three different types: (1) irregular or spherical root vegetables, stem vegetables, cabbage leafy vegetables, bulbous leafy vegetables, eggplants, and gourd vegetables; (2) regular (quasi-cylindrical) root vegetables and legume vegetables; (3) long strips or soft texture ordinary leafy vegetables, spicy leafy vegetables, cauliflowers, and legume vegetables. Secondly, three feeding modes are set up for the three different types of vegetables, namely, the feeding hopper, the circular feeding port and the conveyor belt. Finally, a total of four knife types, namely, the three-leaf arc-shaped convex blade knife set, the comb-shaped blade wire knife set, the arc-shaped slice knife set and the mesh dicing knife set, are designed to meet the needs of segmentation, shredding, slicing and dicing (blocks). According to the four vegetable cutting needs of segmentation, shredding, slicing and dicing (blocks) for the three different types of vegetables, the most suitable cutting method is selected from the three feeding methods of the feeding hopper, the circular feeding port and the conveyor belt and the four cutting knife types of the three-leaf arc-shaped convex blade knife set, the comb-shaped blade wire knife set, the arc-shaped slice knife set and the mesh dicing knife set. This "special vegetable special cutting" usage method can ensure that the output quality of the vegetable cutter does not change, and can maximize the working efficiency of the vegetable cutter to achieve the effect of both quality and quantity. At the same time, the size of the vegetable cutter is reduced, the usage space is saved, the multi-head is changed to a single head, and a double feed port is set on the single head to meet the needs, the internal structure of the vegetable cutter is optimized, the operation difficulty and transportation cost are reduced, and a modular design scheme is adopted in the design process, which makes the problem troubleshooting and maintenance of the vegetable cutter easier, making it more competitive in the market.

[0035] The main work content of the vegetable cutter is to complete the cutting of vegetables. The cutting process of the vegetable cutter is mainly completed by four blades: three-leaf arc knife, comb-shaped blade wire knife, arc-shaped slice knife, and mesh dicing knife. The working process of the vegetable cutter is as follows Figure 2As shown in the figure, the vegetable cutter is designed with three sets of working processes according to different types of vegetables. (1) Irregular or spherical root vegetables, stem vegetables, cabbage leafy vegetables, bulb leafy vegetables, eggplants and gourds are put into the hopper. Under the combined action of gravity, the pressure of the outer cover and the knife disc on the vegetables, and the shear force of the blade on the vegetables, the cut vegetables pass through the gap between the blade on the knife disc and the stainless steel disc, and finally fall out of the discharge port under the action of gravity. (2) Regular (quasi-cylindrical) root vegetables and legume vegetables are fed in through the circular inlet. Under the combined action of manual push, the pressure of the knife disc on the vegetables, and the shear force of the blade on the vegetables, the cut vegetables pass through the gap between the blade on the knife disc and the stainless steel disc, and finally fall out of the discharge port under the action of gravity. (3) Ordinary leafy vegetables, spicy leafy vegetables, cauliflowers and legumes with long strips or soft texture are fed by the conveyor belt. The rotating three-leaf arc-shaped knife cuts the vegetables into filaments or segments, and finally falls out of the outlet under the action of gravity. This multifunctional automatic vegetable cutter uses a one-time forming method for the processing of the entire vegetable. Compared with the traditional vegetable cutter that requires secondary processing to form, the efficiency has been greatly improved, and there is no dead angle in processing. The uniformity and regularity of the finished product have also been significantly improved.

[0036] In an embodiment of the present invention, the cutting mechanism further comprises: A cutting motor, wherein the specifications of the cutting motor are calculated based on the resistance and production efficiency of the root vegetable structure.

[0037] In the embodiment of the present invention, the motor of the cutting blade of the vegetable cutter is a three-phase motor. The power Pd required by the cutting blade of the vegetable cutter is calculated as follows: Where: The motor power of the cutting blade of the automatic vegetable cutting machine; is the resistance torque of the cutting blade of the automatic vegetable cutting machine, in N·m; The speed of the cutting blade of the automatic vegetable cutting machine, in r / min; It is the total efficiency of the cutting part of the automatic vegetable cutting machine.

[0038] The main source of resistance torque of the vegetable cutter is the resistance of destroying the vegetable structure during cutting. Since the resistance of leafy vegetables is usually smaller than that of root vegetables, the resistance of the root vegetables is used as the basis for calculation. Among the root vegetables, the average resistance of potatoes with larger structural resistance is P=0.3 Kg / mm. According to the technical indicators of the vegetable cutter, the production efficiency is 700 Kg / h, and the rotation speed of the turntable is determined. The production efficiency formula is shown as follows:

[0039] In the formula, Q is the production efficiency, which is 700 kg / h according to the technical index, n is the rotation speed of the cutter disc, Z is the number of blades of the automatic vegetable cutter, and the number of arc-shaped blades is selected for calculation, that is, 2; L is the slice thickness, and 0.5 is taken as the calculated value; S is the slice length, which is 60; P is the resistance, and the average resistance of potatoes is selected as P=0.3 Kg / mm; K1 is the utilization rate of the blade, which is 0.7; K2 is the non-suspended rate of the blade, which is 0.2; Substituting the values ​​into the production efficiency formula, we have:

[0040] The solution is n=463 rpm, T=900kg·mm. Since it passes through a set of conveyor belts and the transmission ratio is 2.2, the actual n=2.2n=102 rpm. Substitute it into the power calculation formula:

[0041] In the transmission of the cutting system of the vegetable cutter, the power output by the three-phase motor needs to pass through a belt drive and a set of bearings. Band = 0.99, Bearing = 0.99, so the total efficiency is:

[0042] is the total efficiency of a belt drive and a set of bearings, S is the safety factor. In order to ensure that the vegetable cutter can cope with special situations when working, a safety factor of 1.5 is set, that is, S=1.5, so the final power is:

[0043] Based on the above content, the three-phase reduction motors with wide application range and mature technology on the market were screened, and finally the CH32-1500-3-90 three-phase reduction motor with a reduction ratio of i=1:30 was determined. The rated speed of this motor is 1400rpm and the rated power is 1500w, which can meet the technical index requirements of this design. Figure 7 shown.

[0044] In an embodiment of the present invention, the cutting mechanism further comprises: a cutting spindle, and the diameter of the cutting spindle is determined based on the calculated minimum shaft diameter and the influencing factors of the cooperation with the transmission mechanism.

[0045] The transmission efficiency of the conveyor belt drive of the vegetable cutter is 0.96, and the efficiency of the rolling bearing of the cutting system of the vegetable cutter is 0.99. By calculating the corresponding power, speed and torque, as well as the speed and output power of the selected CH32-1500-3-90 three-phase reduction motor, the following related parameters can be obtained:

[0046] The material of the shaft of the cutting blade of the vegetable cutter will be 45 steel with good cold and hot processing performance and mechanical properties. After quenching and tempering treatment, 45 steel After determining the material of the cutter shaft, its minimum diameter can be determined by calculation:

[0047] Since the cutter shaft needs to cooperate with the pulley, the minimum shaft diameter is planned to be 25 mm. The force analysis of the cutter shaft is carried out. The cutter shaft is subjected to the gravity of the cutter and the power required for slicing. The mass of the cutter shaft and the cutter is estimated using the SoldWorks software. The specific process includes opening the Solidworks software, opening the cutter shaft or cutter part, clicking the evaluation option in the SoldWorks software, and viewing the mass properties, such as density = 0.000, mass = 0.659, and volume = 659246. Since the density display is incorrect, the density or material needs to be set. After setting, click the application option in the SoldWorks software. After evaluation, the mass of the cutter shaft is 2.6 kg, so the comprehensive force is 224 N. The structure of the cutting spindle is as follows: Figure 8 shown.

[0048] Based on any of the above embodiments, the transmission mechanism includes a conveyor belt and a conveyor belt motor: The specifications of the conveyor belt motor are obtained by modeling and simulation analysis based on the mass of materials carried on the conveyor belt.

[0049] When choosing a conveyor belt motor, we need to consider the need for the conveyor belt to "stop when we want and start when we want". At the same time, we also need to adjust the size and specifications of the vegetables according to the speed of the cutter. Therefore, a servo motor is used as the conveyor belt motor.

[0050] The conveyor belt mainly relies on friction to transport materials. Before calculating the power, the friction torque between the belt and the roller is calculated first. The belt is made of rubber material, and the roller is made of lightweight and corrosion-resistant aluminum alloy material. The friction coefficient between the rubber material and the stainless steel material is: In addition to the friction coefficient, the resistance of the conveyor belt also needs to be calculated. The mass of the material to be carried needs to be understood. Root vegetables are usually placed on the conveyor belt, and their maximum load mass is estimated to be 10kg. SoldWorkers software is used for modeling and simulation analysis. The material properties of stainless steel are given to the roller and the material properties of rubber are given to the conveyor belt. After simulation and calculation by Solidworks software, the total mass of the loaded material is obtained as follows: .

[0051] The calculation formula for the torque required for the conveyor belt part of the vegetable cutter is:

[0052] Where: T is the torque required for the conveyor belt, u is the friction coefficient between rubber and aluminum alloy, m is the total mass of the load, g is the acceleration of gravity, and L is the radius of the roller. Substitute the data into the following formula:

[0053] According to the maximum efficiency of the cutter part of 300 kg / h, the advance rate is 119.1 m per minute;

[0054] Considering the possibility of unexpected situations, the safety factor is set to 2, that is, S=2;

[0055] According to the calculation results, the 80ST-M01330 servo motor was finally selected. The rated speed of this motor is 3000rpm and the rated power is 400w, which can meet the power requirements of the conveyor belt. Fig. 9 shown.

[0056] In an embodiment of the present invention, the transmission mechanism further includes a small pulley, and the length of the conveyor belt is obtained by direct calculation based on the power of the cutting motor and the small pulley.

[0057] Since the selected CH32-1500-3-90 three-phase asynchronous motor has a power of 1500w, the power is:

[0058] Where: KA is the working condition coefficient, take 1.2, then:

[0059] According to the design, the diameter of the belt drive pulley of the vegetable cutter is proposed to be 90 mm, and there is a 1% motion sliding strain.

[0060]

[0061] In the formula, ε is the strain during the sliding process. :

[0062] Where: D 1is the diameter of the large pulley of the belt drive, D 2 It is the diameter of the small pulley of the belt drive.

[0064] After calculation and analysis combined with the actual situation, we get

[0066] The belt reference length of the vegetable cutter conveyor belt is

[0067] Calculate the angle of the small pulley of the vegetable cutter conveyor belt:

[0070] The number of bands needs to be an integer, that is, Z=2

[0073] Load on some shafts of the vegetable cutting machine conveyor belt:

[0074] Based on any of the above embodiments, the feed hopper has an inclination angle, and the inclination angle is set according to the friction coefficient between the vegetables and the feed hopper and the force conditions of the vegetables in the feed hopper.

[0075] Hopper structure Fig.10As shown, the hopper is an important mechanism to ensure smooth material supply and no blockage. According to the appearance characteristics of the machine, the hopper will be designed to be inclined so that vegetables can slide freely under the action of gravity. In order to allow the vegetables to quickly contact the cutter after entering the hopper and complete the cutting, the friction coefficient f=0.4 is determined, and the force analysis of the state of the vegetables in the hopper is carried out. In order to make the vegetables slide smoothly in the hopper, FR=FN+F1 is required, α>δ, then: Gsin(α-δ)>0, when α>δ, the material can slide smoothly.

[0076] Depend on , and ,Pick , That is, the hopper tilt angle is .

[0077] Vegetable cutter top view Fig.11 As shown, the whole machine body is welded by the machine base and the box body. The motor of the cutter part is placed in the lower middle part of the box body, and the motor of the conveyor belt part is placed in the upper middle part. The whole appearance is covered with 304 stainless steel, and then connected with the box body and the box cover of 304 stainless steel to ensure the relative airtightness of the box body and make the overall structure safe and hygienic.

[0078] The vegetable cutter provided by the embodiment of the present invention is designed according to the structure of the traditional single-head vegetable cutter. It is easy to operate and maintain, has a reasonable structure, is small in size, has a low manufacturing cost, is highly durable, and is a new type of multifunctional automatic vegetable cutter with strong stability. It can handle most of the root vegetables, stem vegetables, leafy vegetables, cauliflowers, and fruit vegetables on the market, and can meet the needs of segmenting, shredding, slicing, and dicing (blocking) of different types of vegetables. Three feeding methods and four special blade combination designs, "special vegetables for special mouths", root vegetables, stem vegetables, cabbage leafy vegetables, bulbous leafy vegetables, eggplants, and gourds are put in through the feeding hopper; root vegetables and legume vegetables are pushed in through the circular feeding hopper; ordinary leafy vegetables, spicy leafy vegetables, cauliflowers, and legume vegetables are fed in through the conveyor belt.
