Description

Technical Field

[0001] This utility model relates to the technical field of food quantitative dispensing equipment, specifically to a rice dispensing machine. Background Technology

[0002] The prior art CN202421012768.6 discloses a self-service rice serving machine with heat preservation and moisture retention. It is relatively small in size and suitable for small and medium-sized canteens. Furthermore, it uses a feeding screw placed obliquely in the rice storage chamber to continuously transport the rice in the rice storage chamber to the quantitative mechanism at the rice outlet for rice distribution, which is relatively convenient to operate.

[0003] However, in order to match the stroke and pushing efficiency of the feeding screw, the angle of the feeding screw in this design cannot be too large. The small angle means that the rice storage compartment will not have a large capacity. Even if the feeding screw is replaced with other feeding structures, there will inevitably be a problem of idle stroke, which will result in insufficient utilization of the output power of the equipment. At the same time, its storage space also needs to be designed in an inclined state, which makes the rice storage capacity of this type of rice scooping machine small (usually <20 catties of rice), and the rice is not easy to scoop out completely, requiring frequent replenishment of rice to avoid the above situation.

[0004] Therefore, although the existing design has the advantages of small size and easy configuration, it has some shortcomings that cannot be ignored and deserves improvement. Utility Model Content

[0005] To address the technical deficiencies in the background technology, this utility model proposes a rice serving machine that solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0006] A rice serving machine includes a frame, a rice storage compartment fixed inside the frame, and a rice hopper connected to the rice storage compartment. The rice hopper has a rice inlet and a rice outlet. The rice outlet is connected to a rice dispensing component. The upper part of the rice storage compartment has a rice inlet, and the upper part of the rice storage compartment has a feeding component for feeding the rice stored in the rice storage compartment from the upper part of the rice storage compartment into the rice inlet of the rice hopper.

[0007] The rice inlet is located near the upper part of the rice storage compartment. The bottom of the rice storage compartment is open and has a bottom plate that is connected to the output end of the lifting mechanism and can move along the inner wall of the rice storage compartment. As the bottom plate continues to move closer to the feeding assembly, the feeding assembly will continuously feed rice from the rice storage compartment into the rice hopper.

[0008] As a further technical solution of this utility model, the rice dispensing component includes at least a frame connected to the rice hopper, an opening and closing motor fixed in the frame, and a rice baffle plate movably connected to the frame. The output end of the opening and closing motor is connected to the rice baffle plate in a transmission manner.

[0009] As a further improvement to the above technical solution, the rice distribution component also includes a double-headed swing arm fixedly connected to the output end of the opening and closing motor. The opening and closing motor is a rotary motor. The two ends of the double-headed swing arm are symmetrically hinged with transmission rollers. The rice blocking plate includes a rice blocking plate one and a rice blocking plate two that are slidably connected to the frame one.

[0010] The first and second rice-blocking plates are of similar length and are staggered vertically. The first and second rice-blocking plates are flush with each other, so that when the rice-blocking plates are closed, the edges of the first and second rice-blocking plates are tightly fitted together. The first rice-blocking plate has a linkage baffle plate that abuts against the roller at one end in its sliding direction, and a transmission beam that spans across both sides of the first rice-blocking plate along its width direction is fixed at the other end of the first rice-blocking plate.

[0011] The second rice-blocking plate has a transmission beam fixed at one end in its sliding direction, which spans across both sides of the second rice-blocking plate along its width direction. The second transmission beam has a linkage baffle that abuts against the roller. The length direction of the linkage baffle is perpendicular to the sliding direction of the second rice-blocking plate. The other end of the second rice-blocking plate is connected to the first transmission beam through a reset spring.

[0012] As a further improvement to the above technical solution, the frame is provided with a limiting groove 1 that slides with the food-blocking plate 1 and a limiting groove 2 that slides with the food-blocking plate 2, symmetrically along its own center.

[0013] As a further improvement to the above technical solution, the first transmission beam starts from one side of the end of the first rice-blocking plate, crosses the width direction of the second rice-blocking plate, and connects to the other side of the first rice-blocking plate; the second transmission beam starts from one side of the end of the second rice-blocking plate, crosses the width direction of the first rice-blocking plate, and connects to the other side of the second rice-blocking plate.

[0014] As a further improvement to the above technical solution, the shaft of the opening and closing motor is set on the center line of the width direction of the first and second rice-blocking plates. The width direction of the first / second rice-blocking plates is perpendicular to its own sliding direction, and the length of the first / second linkage plate does not exceed half the width of the first / second rice-blocking plates.

[0015] As a further technical solution of this utility model, the feeding assembly includes a frame two connected to the upper part of the food storage compartment, a feeding motor fixed on the surface of the frame two, and a feeding screw that is drivenly connected to the output end of the feeding motor and movably connected in the frame two. The number of feeding screws is ≥1, the height of the feeding screw is greater than the height of the edge of the food inlet, and the feeding screw is horizontal in the axial direction.

[0016] As a further improvement to the above technical solution, the output end of the feeding motor is fixed with a drive gear, and the two shaft ends of the feeding screw are hinged to the frame. One shaft end is fixed with a driven gear that meshes with the drive gear. When the number of feeding screws is greater than 1, the driven gears of adjacent feeding screws mesh with each other, and only one feeding screw has a driven gear that meshes with the drive gear.

[0017] The advantages of this utility model are as follows: Compared with the inclined feeding layout of the prior art, it liberates the arrangement of the feeding structure, enabling it to achieve efficient utilization of zero empty stroke during operation, making rice distribution more efficient, and the rice dispenser can hold more rice at a time, which can effectively reduce the number of times rice needs to be replenished during use. The equipment is also easier to install, use and maintain, which is conducive to its promotion and use in more occasions where rice distribution is needed. Attached Figure Description

[0033] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0034] Combination Figures 1 to 9 As shown, a rice serving machine includes a frame 1, a rice storage compartment 2 fixed inside the frame, and a rice hopper 3 connected to the rice storage compartment 2. The rice hopper 3 has a rice inlet 30 and a rice outlet 31. The rice outlet 31 is connected to a rice dispensing component 4. The upper part of the rice storage compartment 2 has a rice inlet 20, and the upper part of the rice storage compartment 2 has a feeding component 5 for feeding the rice stored in the rice storage compartment 2 from the upper part of the rice storage compartment 2 into the rice inlet 30 of the rice hopper 3.

[0035] The rice inlet 30 is located near the upper part of the rice storage compartment 2. The bottom of the rice storage compartment 2 is open and has a bottom plate 21 that is connected to the output end of the lifting mechanism 22 and can move along the inner wall of the rice storage compartment 2. When the bottom plate 21 continues to approach the feeding assembly 5, the feeding assembly 5 will continuously feed rice from the rice storage compartment 2 into the rice hopper 3.

[0036] Compared with the existing technology, the superior effect of this utility model is mainly reflected in the fact that the lifting mechanism 22 solves the problem of feeding the rice storage compartment 2. The bottom plate 21 can be adaptively adjusted in height through a predetermined non-intelligent program (for example, without the aid of a weight sensor, the height of the remaining rice storage is estimated based on the stroke or working time of the feeding component, and the height of the bottom plate 21 to be raised per unit time is calculated using the above-mentioned functional relationship) or a predetermined intelligent program (for example, a weight sensor is added to the output end of the bottom plate 21 and the lifting mechanism 22, and the programmable program of the controller is designed to calculate the remaining rice storage according to the weight and adaptively adjust the height change of the output end of the lifting mechanism 22, thereby changing the lifting height of the bottom plate 21). The lifting mechanism 22 can be designed and selected according to the actual production and manufacturing conditions, such as the folding frame + servo piston form shown in the schematic diagram of this utility model, or the form of lead screw motor + lead screw stroke block, without being limited to a single form.

[0037] Specific reference Figure 1 As shown, and as a technical supplement, since the bottom plate 21 is movable relative to the rice storage compartment 2, it is also optional to set a scraper-like structure between the edge of the bottom plate 21 and the inner wall of the rice storage compartment 2. Since the bottom plate 21 itself is usually a rigid structure, although it can scrape off the residual rice adhering to the inner wall of the rice storage compartment 2 during contact, there will be no problem in the short-term use of the equipment. However, if used for a long time, the residual rice on the inner wall of the rice storage compartment 2 will inevitably accumulate, affecting the smoothness of the movement of the bottom plate 2. Since the size of this equipment is small, the cleaning difficulty of the rice storage compartment 2 is not high. However, in order to increase the service life of the equipment, it is better to add a scraper-like structure to the edge of the bottom plate 21 to increase the amount of residual rice scraped off. Alternatively, a non-stick coating or structure can be designed for the inner wall of the rice storage compartment 2 to reduce the probability of rice adhering and to greatly prevent rice from falling from the gap between the rice storage compartment 2 and the bottom plate 21.

[0038] Based on the above technical foundation, in the technical solution of this utility model, the rice storage compartment 2 does not need to be set higher than the rice hopper 3, and the feeding component 5 does not need to consider the problem of the height decreasing when the rice stored in the rice storage compartment 2 decreases. The rice storage compartment 2 actively supplies rice, and the feeding component 5 is considered to have rice always available. Therefore, it only needs to achieve the ability to feed rice in the horizontal direction. The horizontal feeding component 5 can liberate the structural thinking. Whether it is a screw-type feeding mechanism or a reciprocating rake feeding method, it can contact the rice throughout its entire stroke range, and there is no problem of empty stroke. Therefore, the rice conveying efficiency is liberated, and the rice output efficiency is significantly improved compared with the prior art. According to actual calculation and comparison, it can significantly increase the rice output speed by at least 35%.

[0039] On the other hand, although the amount of rice served is adjusted according to the needs of the diners, so weight control is a necessary step, the distribution of rice does not require very precise control in actual work. For the same 100g of rice, an error of plus or minus 10g is completely acceptable in the actual dining environment. Therefore, from the basic perspective of saving equipment manufacturing costs, reducing equipment use and maintenance requirements, and improving equipment reliability, the weight sensor 44 is the most direct and effective method compared to flow sensors and photoelectric sensors.

[0040] Combination Figure 1 and Figure 4 As shown, in order to achieve accurate quantitative weighing in the technical solution of this utility model, compared with the method of calculating the margin by the stroke of the feeding mechanism 5 mentioned above, a better weighing solution is to simplify the configuration of the weight sensor 44. Following the above basic perspective, after the frame 40 and the rice hopper 3 are combined to form a fixed whole, one side of the frame 40 is hung on the fixed structure of the frame 1 (such as a hook or hanging rod) in a hinged manner, and the other side is also fixed in the weight sensor 44 in the frame 1 by hanging or other detachable means. The frame 40 is symmetrically arranged at the hinge hanging point and the hanging point of the weight sensor 44, which can provide the necessary technical parameter support for the rice weight sensing of the rice dispensing component 4. The equipment can achieve the technical effect of dispensing rice on demand during operation. In addition, in the above method, the installation and fixing between the frame 40 and the frame 1 is also relatively simple and easy to disassemble and maintain later.

[0041] Combination Figure 1 , Figure 2 As shown, preferably, the rice inlet 30 is basically flush with the rice inlet 20, and the feeding component 5 is basically flush with the rice inlet 20. The feeding component 5 feeds the rice stored in the rice storage chamber 2 from the rice inlet 20 into the rice inlet 30 and then into the rice hopper 3. Being basically flush means that the height of the rice inlet 30 and the rice inlet 20 is similar, and the difference between the two is small. Generally, under the size specifications of this equipment, the difference between the two should not exceed 5 cm. The feeding component 5 can more easily transfer the rice from the rice storage chamber 2 to the rice hopper 3.

[0042] Combination Figures 1 to 7As shown, in one of the preferred embodiments of this utility model, the rice dispensing component 4 includes at least a frame 40 connected to the rice hopper 3, an opening and closing motor 42 fixed in the frame 40, and a rice baffle 43 movably connected to the frame 40. The output end of the opening and closing motor 42 is connected to the rice baffle 43. The rice dispensing component 4 uses the opening and closing motor 42 to drive the rice baffle 43 to achieve the opening and closing operation. When the rice hopper 3 needs to retain rice, the rice baffle 43 closes with the cooperation of the opening and closing motor 42 until a sufficient amount of rice falls onto the surface of the rice baffle 43. Then, the opening and closing motor 42 is driven to open the rice baffle 43, and the rice falls down, completing the rice dispensing work. After that, it closes again to prepare for the next rice dispensing. It can be implemented with reference to the rice dispensing mechanism of the existing rice serving machine, which is very convenient.

[0043] Combination Figures 3 to 7 As shown, as a further optimization of the above embodiment, the rice dispensing component 4 also includes a double-headed swing rod 45 fixedly connected to the output end of the opening and closing motor 42. The opening and closing motor 42 is a rotary motor. The two ends of the double-headed swing rod 45 are symmetrically hinged with transmission rollers 450. The rice blocking plate 43 includes a rice blocking plate 430 and a rice blocking plate 431 that are slidably connected to the frame 40.

[0044] The first rice-blocking plate 430 and the second rice-blocking plate 431 are similar in length and are staggered. The first rice-blocking plate 4302 and the second rice-blocking plate 4312 are flush with each other, so that when the rice-blocking plate 43 is closed, the edges of the first rice-blocking plate 4302 and the second rice-blocking plate 4312 are tightly fitted. The first rice-blocking plate 4300 is provided at one end of its sliding direction with a linkage baffle 4300 that abuts against the roller 450. The other end of the first rice-blocking plate 430 is fixed with a transmission beam 4301 that spans across both sides of the first rice-blocking plate 430 along the width direction of the first rice-blocking plate 430.

[0045] The second rice-blocking plate 431 has a transmission beam 4311 fixed at one end in its sliding direction, which spans across both sides of the second rice-blocking plate 431 along its width direction. The transmission beam 4311 is provided with a linkage baffle 4310 that abuts against the roller 450. The length direction of the linkage baffle 4310 is perpendicular to the sliding direction of the second rice-blocking plate 431. The other end of the second rice-blocking plate 431 is connected to the first transmission beam 4301 through a reset spring 46.

[0046] The above embodiment is a further optimization of the structure of the rice distribution component 4. The rice baffle 43 is composed of rice baffle one 430 and rice baffle two 431 that are linked together. Both are slidably connected to the frame one 40. The periodic rotation of the opening and closing motor 42 on one side drives the double-headed swing arm 45 to move in a sinusoidal motion with peaks and troughs between the linked baffle one 4300 and the linked baffle two 4310, which determines the opening stroke of the rice baffle 43. The closing stroke of the rice baffle one 430 and the rice baffle two 431 is realized by the reset spring 46. The structure is simple, compact and reliable.

[0047] As a supplement, the direction of the staggered layers refers to the vertical ends being up and down when the equipment is placed. The above limitation means that even though the first food baffle 430 and the second food baffle 431 are staggered, they are not strictly separated. Instead, they form a kind of "conjugate" cooperation that mutually restricts and cooperates with each other, providing a better linkage effect, making the action less prone to errors, and minimizing the types and quantities of necessary accessories.

[0048] Combination Figure 5 As shown, as a further optimization of the above embodiment, the frame 40 is provided with a limiting groove 400 that slides with the food blocking plate 430 and a limiting groove 401 that slides with the food blocking plate 431, symmetrically along its own center, to assist in the installation and movement limiting of the food blocking plate 430 and the food blocking plate 431.

[0049] Combination Figures 5 to 7 As shown, as a further optimization of the above embodiment, the first transmission beam 4301 starts from one side of the end of the first rice-blocking plate 430, crosses the width direction of the second rice-blocking plate 431, and connects to the other side of the first rice-blocking plate 430. The second transmission beam 4311 starts from one side of the end of the second rice-blocking plate 431, crosses the width direction of the first rice-blocking plate 430, and connects to the other side of the second rice-blocking plate 431. Through the above structure, the rice-distributing component 4 can realize the cross-arrangement of the first transmission beam 4301 and the second transmission beam 4311, so that the first rice-blocking plate 430 and the second rice-blocking plate 431 are nested in space but do not interfere with each other, making the transmission smoother and less prone to errors. The roller 450 allows the double-headed swing rod 45 to better apply periodic force to the first linkage baffle 4300 and the second linkage baffle 4310.

[0050] Combination Figure 6 and Figure 7As shown, as a further optimization of the above embodiment, the axis of the opening and closing motor 42 is set on the center line of the width direction of the first rice-blocking plate 430 and the second rice-blocking plate 431. The width direction of the first rice-blocking plate 430 / the second rice-blocking plate 431 is perpendicular to its own sliding direction. The length of the first linkage baffle 4300 / the second linkage baffle 4310 does not exceed half the width of the first rice-blocking plate 430 / the second rice-blocking plate 431. The main function of this method is that when the closing process of the rice-blocking plate 43 needs to be executed, only a small amount of the edges of the first linkage baffle 4300 and the second linkage baffle 4310 contact the body of the double-headed swing rod 45. Therefore, the friction is reduced and the return resistance is reduced. At this time, with the action of the reset spring 46, the rice-blocking plate 43 can be closed quickly and smoothly, so as to proceed to the next rice-receiving process.

[0051] Combination Figures 1 to 3 ,as well as Figure 8 , Figure 9 As shown, in one of the preferred embodiments of this utility model, the feeding assembly 5 includes a frame 2 50 connected to the upper part of the rice storage compartment 2, a feeding motor 51 fixed on the surface of the frame 2 50, and a feeding screw 52 that is drivenly connected to the output end of the feeding motor 51 and movably connected within the frame 2 50. The number of feeding screws 52 is ≥1, the height of the feeding screw 52 is greater than the height of the edge of the rice inlet 30, and the feeding screw 52 is horizontal in axis. The horizontally placed feeding screw 52 can efficiently contact rice in any top surface state and push the rice toward the rice inlet 30 of the rice hopper 3. Multiple feeding screws 52 can multiply the rice delivery efficiency. The frame 2 can be equipped with an insulated top plate, or a moisture-retaining structure can be added inside the top plate to ensure that the rice is in a good edible state throughout the entire rice preparation process.

[0052] Combination Figure 8 and Figure 9 As shown, as a further optimization of the above embodiment, the output end of the feeding motor 51 is fixed with a drive gear 53, and the two shaft ends of the feeding screw 52 are hinged to the frame 50. One shaft end is fixed with a driven gear 54 that meshes with the drive gear 53. When the number of feeding screws 52 is greater than 1, the driven gears 54 of adjacent feeding screws 52 mesh with each other. Only one driven gear 54 of the feeding screw 52 meshes with the drive gear 53. This layout is more compact, and adjusting the rotation direction of the feeding screws 52 can ensure that all feeding screws 52 can move forward and backward together.

[0053] In summary, compared to the existing inclined feeding layout, the structural design of this utility model liberates the arrangement of the feeding mechanism 5, enabling it to achieve efficient utilization with zero empty stroke during operation. This makes rice distribution more efficient, and the rice dispenser no longer needs to consider strict coordination with the feeding mechanism 5. The flexible structure of the bottom plate 21 allows the rice dispenser to hold more rice at a time, thereby effectively reducing the number of times rice needs to be replenished during use. Due to the simple and reliable overall structure, the equipment is also easier to install, use, and maintain. Overall, this utility model is undoubtedly more conducive to its widespread use in more occasions where rice distribution is required compared to existing designs.

[0054] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
