A compact rice serving machine

Abstract

This utility model relates to the technical field of food quantitative dispensing equipment, specifically disclosing a compact rice dispenser. It includes a frame, a rice storage compartment fixed within the frame, a rice hopper connected to the storage compartment, a rice dispensing component, and a feeding component. The feeding component is located at the top of the storage compartment and conveys rice from above to the dispensing component. The storage compartment has a bottom plate that rises as the total amount of rice stored decreases, and the dispensing component is also connected to a weight sensor. This utility model rationally optimizes the feeding structure of the storage compartment, transforming the bottom plate into a lifting structure. When the rice in the storage compartment is consumed and the height decreases, the bottom plate actively lifts the rice, thus eliminating the need for the screw-type feeding structure to be completely flat due to stroke limitations. This cleverly improves the utilization rate of the internal volume of the rice dispenser, resulting in high rice conveying efficiency and the ability to hold more rice. The equipment is easy to install, operate, and maintain, making it suitable for a wide range of small and medium-sized canteens.

Description

Technical Field

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

[0002] A rice dispensing machine is an automated device for distributing food in fixed quantities. It is designed to solve the problem of dispensing rice in multiple batches in canteens and other places where a large number of people are eating. Existing rice dispensing equipment is often quite bulky. Although the rice storage capacity is also increased, replenishing rice, moving and placing the equipment, as well as the initial assembly and subsequent maintenance of the equipment, all become more inconvenient. Moreover, it is mainly designed for large canteens and other places with a large number of people. For small and medium-sized canteens that also have a large number of diners but are not large in scale, it becomes more impractical and has high operating costs.

[0003] In response to this, the existing technology CN202421012768.6 discloses a self-service rice dispenser with heat preservation and moisture retention. It is relatively small in size and suitable for small and medium-sized canteens. It uses a feeding screw placed at an angle in the rice storage compartment to continuously transport the rice in the storage compartment to the quantitative mechanism at the rice outlet for dispensing. The operation is relatively convenient. However, in order to match the stroke and pushing efficiency of the feeding screw, the angle of the feeding screw cannot be too large. The small inclination angle determines that the rice storage compartment with the feeding screw will not have a large capacity. At the same time, its storage space also needs to be designed in an angled state, which makes the rice storage capacity of this type of rice dispenser small (usually <20 catties of rice), and the rice is not easy to clean completely. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes a compact rice serving machine, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] A compact 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.

[0006] The rice inlet is located near the upper part of the rice storage compartment. The upper part of the rice storage compartment is equipped with a feeding assembly for feeding the rice stored in the rice storage compartment into the rice hopper from the upper part of the rice storage compartment. The rice storage compartment is open from top to bottom, and the bottom opening is equipped with 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.

[0007] The rice dispensing assembly includes at least a frame connected to the rice hopper, a feeding port disposed in the frame and communicating with the rice outlet, an opening and closing motor fixed in the frame, and a rice baffle plate for blocking the feeding port and movably connected to the frame. The output end of the opening and closing motor is connected to the rice baffle plate. One side of the frame in the length direction is hinged to the machine frame, and the other symmetrical side is connected to a weight sensor for detecting the weight of the rice in the rice hopper. The weight sensor is fixedly connected to the machine frame.

[0008] The weight sensor, opening and closing motor, material feeding assembly, and lifting mechanism are all connected to a controller.

[0009] 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.

[0010] As a further preferred embodiment of 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.

[0011] As a further technical solution of this utility model, the rice dispensing 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 rollers with a diameter greater than the width of the double-headed swing arm. The rice blocking plate includes a rice blocking plate one and a rice blocking plate two that slide in the horizontal direction.

[0012] Both the first and second rice-blocking plates are slidably connected to the first frame. The first rice-blocking plate has a linkage baffle plate at one end of its sliding direction that abuts against the roller. The length direction of the linkage baffle plate is perpendicular to the sliding direction of the first rice-blocking plate. The other end of the first rice-blocking plate is fixed with a transmission beam that spans across both sides of the first rice-blocking plate along its width direction.

[0013] 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.

[0014] As a further preferred embodiment of 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.

[0015] As a further preferred embodiment of the above technical solution, the first and second rice-blocking plates are staggered in the vertical direction. The first rice-blocking plate is provided with a first blocking plate, and the second rice-blocking plate is provided with a second blocking plate. The first and second blocking plates are flush with each other, and when the first and second rice-blocking plates are in a closed state, the edges of the first and second blocking plates are in contact. 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.

[0016] As a further preferred embodiment of the above technical solution, the shaft of the opening and closing motor is located 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.

[0017] As a further technical solution of this utility model, a cleaning port is provided on the lower side wall of the food storage compartment.

[0018] As a further technical solution of this utility model, the rice inlet is basically flush with the rice placement inlet, the feeding component is basically flush with the rice placement inlet, and the feeding component feeds the rice stored in the rice storage compartment into the rice inlet from the rice placement inlet and then into the rice hopper.

[0019] The beneficial effects of this utility model are as follows: the feeding structure of the rice storage compartment has been rationally optimized, and the bottom plate of the compartment has been transformed into a lifting structure. When the rice in the storage compartment is consumed and the height decreases, the rice can be actively lifted, so that the screw feeding structure no longer needs to be completely flat to adapt to the stroke limitation. This allows the screw feeding structure to fully liberate the conveying efficiency. Compared with the prior art, it greatly expands the space of the rice storage compartment and improves the effective volume utilization rate of the rice serving machine without significantly affecting the overall volume control of the rice serving machine. Combined with a simple and reliable rice dispensing mechanism, the equipment is not only easy to install and maintain, but also convenient to use. The production and utilization costs of the equipment are also effectively controlled, making it suitable for a wide range of small and medium-sized canteens. Attached Figure Description

[0037] 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.

[0038] Combination Figures 1 to 10 As shown, a compact rice serving machine includes a frame 1, a rice storage compartment 2 fixed in the frame 1, and a rice hopper 3 connected to the rice storage compartment 2. The rice hopper 3 is provided with 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 is provided with a rice inlet 20.

[0039] The rice inlet 30 is located near the upper part of the rice storage compartment 2. The upper part of the rice storage compartment 2 is provided with a feeding component for feeding the rice stored in the rice storage compartment 2 into the rice inlet 30 of the rice hopper 3. The rice storage compartment 2 is open from top to bottom, and the bottom opening is provided with 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. As the bottom plate 21 continues to approach the feeding component, the feeding component will continuously feed rice from the rice storage compartment 2 into the rice hopper 3.

[0040] The rice dispensing component 4 includes at least a frame 40 connected to the rice hopper 3, a feeding port 41 disposed in the frame 40 and communicating with the rice outlet 31, an opening and closing motor 42 fixed in the frame 40, and a rice baffle plate 43 for blocking the feeding port 41 and movably connected to the frame 40. The output end of the opening and closing motor 42 is connected to the rice baffle plate 43 in a transmission manner. One side of the frame 40 in the length direction is hinged to the frame 1, and the other symmetrical side is connected to a weight sensor for detecting the weight of rice in the rice hopper 3. The weight sensor is fixedly connected to the frame 1.

[0041] The weight sensor, opening and closing motor 42, material feeding assembly, and lifting mechanism 22 are all connected to a controller.

[0042] Specific reference Figure 1As shown, the superior effect of this utility model compared to the prior art 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.

[0043] Continue to refer to 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.

[0044] 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%.

[0045] On the other hand, while the amount of rice served is adjusted according to the diners' needs, making weight control a necessary step, the actual distribution of rice does not require extremely precise control. A 10g error in the same 100g of rice is perfectly acceptable in a real dining environment. Therefore, considering the fundamental aspects of saving equipment manufacturing costs, reducing equipment usage 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. In the technical solution of this utility model, the placement of the weight sensor 44 also follows the above-mentioned basic principles. Specifically, see here for details. Figure 1 and Figure 4 As shown, after the frame 40 and the rice hopper 3 are combined to form a fixed whole, one side of the frame 40 (the left side centered on the rice hopper 3) 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 (the right side centered on the rice hopper 3) 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, the installation and fixing between the frame 40 and the frame 1 is relatively simple and easy to disassemble and maintain later.

[0046] Combination Figure 5 and Figure 6 As shown, in one of the preferred embodiments of this utility model, the feeding assembly includes a second frame 50 connected to the upper part of the rice storage compartment 2, a feeding motor 51 fixed to the surface of the second frame 50, and a feeding screw 52 that is drivenly connected to the output end of the feeding motor 51 and movably connected to the second frame 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 the 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 second frame 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.

[0047] Combination Figure 5 and Figure 6As 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.

[0048] Combination Figures 7 to 10 As shown, in one of the preferred embodiments of the present invention, the rice dispensing component 4 further 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 rollers 450 with a diameter greater than the width of the double-headed swing rod 45. The rice blocking plate 43 includes a rice blocking plate 1 430 and a rice blocking plate 2 431 that slide in the horizontal direction.

[0049] Both the first rice-blocking plate 430 and the second rice-blocking plate 431 are slidably connected to the first frame 40. The first rice-blocking plate 430 is provided with a linkage baffle 4300 at one end of its sliding direction, which abuts against the roller 450. The length direction of the linkage baffle 4300 is perpendicular to the sliding direction of the first rice-blocking plate 430. 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 430 degrees of the first rice-blocking plate.

[0050] 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.

[0051] 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 return spring 46. The structure is simple, compact and reliable. The straddle arrangement of the transmission beam one 4301 and the transmission beam two 4311 allows the rice baffle one 430 and the rice baffle two 431 to be nested in space without interfering with each other, making the transmission smoother and less prone to errors. The roller 450 allows the double-headed swing arm 45 to better apply periodic force to the linked baffle one 4300 and the linked baffle two 4310.

[0052] like Figure 7 and Figure 8 As shown, as a further optimization of the above embodiment, the frame 40 is symmetrically 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. The limiting groove 400 and the limiting groove 401 are used to assist in the installation and movement limiting of the food-blocking plate 430 and the food-blocking plate 431.

[0053] Combination Figures 7 to 10 As shown, as a further optimization of the above embodiment, the first food-blocking plate 430 and the second food-blocking plate 431 are staggered in the vertical direction. The first food-blocking plate 430 is provided with a first blocking piece 4302, and the second food-blocking plate 431 is provided with a second blocking piece 4312. The first blocking piece 4302 and the second blocking piece 4312 are flush with each other, and when the first food-blocking plate 430 and the second food-blocking plate 431 are in the closed state, the edges of the first blocking piece 4302 and the second blocking piece 4312 are in contact. The first transmission beam 4301 starts from one side of the end of the first food-blocking plate 430, crosses the width direction of the second food-blocking plate 431, and connects to... On the other side of the first food baffle 430, the second transmission beam 4311 starts from one side of the end of the second food baffle 431, crosses the width direction of the first food baffle 430, and connects to the other side of the second food baffle 431. As a supplement, the vertical direction refers to the up and down direction. The above limitation ensures 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 reducing the types and number of necessary accessories to a minimum.

[0054] Combination Figures 7 to 10As 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.

[0055] Combination Figure 11 As shown, in one of the preferred embodiments of this utility model, a cleaning port 23 is provided on the lower side wall of the food storage compartment 2. The cleaning port 23 is mainly provided to serve the cleaning and maintenance needs after the equipment is used. The position of the cleaning port 23 should be as low as possible, while the minimum value of the working stroke range of the bottom plate 21 should be higher than the cleaning port 23. When it is necessary to clean the inner wall of the food storage compartment 2, the bottom plate 21 can be lowered further beyond the height of the cleaning port 23 to realize the drainage operation of the cleaning water in the food storage compartment 2.

[0056] This can be referenced. Figure 1 and Figure 2 As shown, in one of the preferred embodiments of this utility model, 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. 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 screw 52 of the feeding component 5 can more easily transfer the rice from the rice storage chamber 2 to the rice hopper 3.

[0057] In summary, compared with the prior art, this utility model has made reasonable optimization to the feeding structure of its food storage compartment 2, and changed the bottom plate 21 of the compartment into a lifting movable structure. This design allows the screw-type feeding component 5 to no longer need to be completely flat to adapt to the travel limit of the feeding screw 52, ​​and the food storage compartment 2 actively adapts to the height of the feeding screw 52.

[0058] When the rice in the rice storage compartment 2 is consumed and the height decreases, the bottom plate 21 actively lifts the rice through the lifting mechanism 22, so that the screw feeding structure can fully contact the rice, making good use of the entire stroke length of the feeding screw 52, ​​thereby improving the rice conveying efficiency of the feeding component 5.

[0059] From the above analysis, compared with the prior art, since the feeding mechanism 5 is placed horizontally and the volume of the rice storage compartment 2 can change with the amount of rice stored, the overall structure design of the equipment can achieve better internal space utilization efficiency, greatly expanding the space of the rice storage compartment 2 and improving the efficiency of rice conveying. Furthermore, the overall structure of the equipment described in this utility model is not complicated, and manufacturers can choose the lifting mechanism 22 that can achieve the technical solution of this utility model to achieve good cooperation with the bottom plate 21. Therefore, the equipment structure is also very reliable.

[0060] In this way, not only is the equipment itself easy to install and maintain, but it is also relatively convenient to use. The production and utilization costs of the equipment are also effectively controlled, making it more suitable for small and medium-sized canteens and other dining venues with limited operating costs.

[0061] 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.
