Description

Technical Field

[0001] The present invention belongs to the technical field of catering equipment, and particularly relates to an automatic rice dispenser. Background Art

[0002] When we get rice in the canteen or restaurant, the rice is filled into the container manually. Manual rice serving makes it difficult to accurately control the amount of served rice. Moreover, the degree of rice compaction is uncertain, which affects the shaping of rice in the container. The traditional manual rice serving has low efficiency.

[0003] The invention patent application No. CN201210342871.2 discloses an automatic rice dispenser, which includes a frame. From top to bottom within the frame, there are successively an extrusion mechanism, a rice hopper, at least three sets of quantitative rice serving devices, a rice outlet trough, a dinner plate positioning device and a rice dispenser control system; the extrusion mechanism includes a motor, a screw rod and a pressing block. One end of the screw rod is connected to the motor, and the other end is connected to the pressing block; each set of quantitative rice serving device includes a quantitative rice trough, a blade, a pushing block and a cylinder. The piston rod of the cylinder is connected to the pushing block. The pushing block is slidably placed at one end of the quantitative rice trough. The blade is placed above the quantitative rice trough and is flush with the opening above the quantitative rice trough. One end of the blade is fixedly connected to the pushing block; the dinner plate positioning device includes cylinders respectively placed around the platform. The end of the piston rod of the cylinder is equipped with a pushing plate; by adopting the extrusion mechanism, the quantitative rice serving device and the dinner plate positioning device, and connecting with the rice dispenser control system, an unattended self-service form is realized, the efficiency of rice serving is improved, and the accuracy of the amount of each serving of rice is ensured.

[0004] The rotational motion of the motor is converted into the downward motion of the pressing block. Under the extrusion of the pressing block, the rice passes through the outlet of the rice hopper and enters the quantitative rice trough. The amount of rice loaded in the quantitative rice trough is the amount required by the diner. Then, the piston rod of the cylinder pushes the pushing block to push the rice out of the quantitative rice trough and into the rice outlet trough, and then falls from the outlet of the rice outlet trough into the dinner plate.

[0005] In the above device, the purpose of extruding the rice is to squeeze the rice into the rice trough to achieve discharging. Pressing the upper part of the rice by the pressing block will cause the rice in the hopper to be caked, so that it is impossible to ensure that the lower-layer rice smoothly enters the rice trough and fills the voids in the rice trough. After the rice is integrally extruded, the taste of the rice is reduced. Summary of the Invention

[0006] In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide an automatic rice dispenser that can quantitatively and shape the rice.

[0007] The technical solution adopted by the present invention is as follows:

[0008] An automatic rice cooker comprises a frame, on which a hopper is mounted; a mounting plate is fixed to the frame, an upper cylinder is connected to the mounting plate, and the upper cylinder is located at the lower side of the hopper; a lifting mechanism is also mounted on the frame, an output end of the lifting mechanism is connected to a lifting plate, a lower cylinder is connected to the lifting plate, and the lower cylinder is located at the lower side of the upper cylinder; a cardboard driving mechanism is mounted on both the mounting plate and the lifting plate, an upper cardboard is connected to the output end of the cardboard driving mechanism on the mounting plate, a lower cardboard is connected to the output end of the cardboard driving mechanism on the lifting plate, the upper cardboard is located at the lower end of the upper cylinder, the lower cardboard is located at the lower end of the lower cylinder, a clearance notch is provided on the lower cylinder, and the upper cardboard is sleeved in the clearance notch.

[0009] Pour the rice into the hopper, and the breaking mechanism will break the rice up fully. The broken rice will fall into the lower cylinder through the upper cylinder, and then the upper card will be closed and the upper cylinder will be driven up by the lifting mechanism, and the rice in the lower cylinder will be compressed and shaped. Then the lower card will be opened, and the shaped and quantitative rice will be put into the container.

[0010] The breaking mechanism of the present invention can break up the rice sufficiently so that the rice can fall smoothly into the upper cylinder and the lower cylinder. After the rice falls into the lower cylinder, the upper clamping plate is closed so that the rice can be quantitatively controlled. When the lower cylinder is driven to rise, the rice is compressed and shaped to ensure that the rice will not scatter when it is served. The rice-beating efficiency can be improved by using the present invention. The purpose of driving the lower cylinder to rise to press and shape the rice is to ensure that the rice maintains its shape after falling onto the plate. If the amount of pressed rice is small, it is easy to control the degree of pressing and will not cause the rice to become compacted. After the loose rice enters the lower cylinder and is then pressed, it can avoid the situation where the whole rice becomes compacted when the rice in the hopper is directly pressed.

[0011] As a preferred embodiment of the present invention, a scattering mechanism is installed in the hopper, and the scattering mechanism includes a plurality of scattering roller mounting shafts, the rotating shafts of the scattering roller mounting shafts are connected to the hopper, a plurality of scattering rollers are installed on the scattering roller mounting shafts, the plurality of scattering roller mounting shafts are connected by gear transmission, and one of the scattering roller mounting shafts is connected to a motor by a connecting shaft. The motor drives one of the scattering roller mounting shafts to rotate, and the plurality of scattering roller mounting shafts are connected by gear transmission. When the scattering roller mounting shafts rotate, the scattering rollers thereon can fully scatter the agglomerated rice, ensuring that the rice can smoothly fall into the upper barrel and the lower barrel.

[0012] As a preferred solution of the present invention, a slideway is fixed on the frame, a slide rail is fixed on the hopper, the slide rail is sleeved in the slideway, and a locking screw for locking the slide rail is threadedly connected to the frame. The slide rail on the hopper can slide in the slideway, which is convenient for adjusting the position of the hopper and for disassembling and assembling the hopper.

[0013] As a preferred embodiment of the present invention, the upper cylinder includes a conical cylinder, which is located at the lower side of the hopper, a blanking cylinder is fixed at the lower end of the conical cylinder, and the lower cylinder is sleeved outside the blanking cylinder; a leak-proof cylinder is fixed on the blanking cylinder, which is sleeved outside the lower cylinder, and the leak-proof cylinder is located at the lower side of the upper clamping plate. When the lower cylinder is lowered, the leak-proof cylinder blocks the clearance gap of the lower cylinder. The upper end of the conical cylinder is open to prevent the rice from spilling to the outside when falling into the upper cylinder. The lower cylinder is sleeved outside the blanking cylinder, so that the rice can accurately fall from the upper cylinder into the lower cylinder. When the lower cylinder is lowered, the leak-proof cylinder blocks the clearance gap of the lower cylinder to prevent the rice from leaking out of the clearance gap.

[0014] As a preferred embodiment of the present invention, the lower cylinder is conical in shape, and the lower end opening of the lower cylinder is larger than the upper end opening of the lower cylinder. When the lower cylinder rises, the upper clamping plate presses the rice, and the adhesion between the rice and the lower cylinder increases. The lower cylinder of the present invention has a certain taper, so when the lower clamping plate is opened, the rice can fall smoothly under the action of gravity, avoiding the situation where the rice cannot be discharged due to the rice being pressed.

[0015] As a preferred embodiment of the present invention, the cardboard driving mechanism includes a steering gear and a slideway mounted on a mounting plate or a lifting plate, the output end of the steering gear is connected to a cantilever, and the other end of the cantilever is rotatably connected to a guide block; a slider is sleeved in the slideway, the slider is sleeved in the slideway, a guide groove is fixed on the slider, the guide block is sleeved in the guide groove, and the upper cardboard or the lower cardboard is connected to one end of the slider. The steering gear drives the cantilever to rotate, and the cantilever pushes the guide groove to move through the guide block. Since the guide groove is fixed to the slider and the slider is sleeved in the slideway, the slider can move linearly in the slideway. Under the push of the slider, the upper cardboard or the lower cardboard can be accurately moved in or out, so that the lower end of the upper tube or the lower tube can be closed or opened. The movement of the upper cardboard and the lower cardboard is automatically controlled by the cardboard driving mechanism, which is convenient for automatic control.

[0016] As a preferred solution of the present invention, the number of the upper and lower cardboards is two, each upper cardboard or lower cardboard is connected to a cardboard driving mechanism, and the shape of the upper and lower cardboards is semicircular. The two cardboard driving mechanisms synchronously control the two upper cardboards, and the lower end of the upper tube is closed when the two upper cardboards are spliced ​​together. The two cardboard driving mechanisms synchronously control the two lower cardboards, and the lower end of the lower tube is closed when the two lower cardboards are spliced ​​together.

[0017] As a preferred solution of the present invention, the mounting plate is fixed with a limited slide groove, the upper cylinder is provided with two half-clip rings, the half-clip rings are provided with a clamping block, the clamping block is sleeved in the limited slide groove, and the two half-clip rings are connected by a locking rod. The two half-clip rings can be locked by the locking rod, so that the upper cylinder is fixed. When the upper cylinder needs to be disassembled for cleaning, it only needs to loosen the locking rod, which is easy to operate.

[0018] As a preferred embodiment of the present invention, a limiting block is fixed on the lifting plate. A limiting groove is provided on the limiting block, and a limiting convex block is provided on the lower cylinder. The limiting convex block is sleeved in the limiting groove, and a locking tongue for clamping the limiting convex block is connected to the limiting groove. The limiting groove on the limiting block can limit the limiting convex block of the lower cylinder, and then the limiting convex block is locked by the locking tongue, so as to reliably fix the lower cylinder. When it is necessary to disassemble the lower cylinder for cleaning, only need to unscrew the locking tongue and lower the lower cylinder, then the lower cylinder can be taken out smoothly.

[0019] As a preferred embodiment of the present invention, the lifting mechanism includes a lifting mounting plate. The lifting mounting plate is mounted on the frame, and a linear motor is mounted on the lifting mounting plate. The output end of the linear motor is connected to the lifting plate. The linear motor can drive the lifting plate to accurately lift and lower, so that the lower cylinder can accurately lift and lower with the lifting plate.

[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The dispersing mechanism of the present invention can fully disperse the rice so that the rice can smoothly fall into the upper cylinder and the lower cylinder. After the rice falls into the lower cylinder, close the upper clamping plate to quantitatively control the rice. When driving the lower cylinder to rise, the rice is compressed and shaped to ensure that the rice will not scatter when served. Using the present invention for serving rice can improve the serving efficiency.

[0022] 2. By driving the lower cylinder to rise to compress and shape the rice, the purpose is to ensure that the rice maintains its shape after falling onto the dinner plate. If the amount of the pressed rice is small, it is easy to control the pressing degree and it will not cause the rice to become lumpy. After the loose rice enters the lower cylinder and then is pressed, it can avoid the situation that the whole rice becomes lumpy when directly pressing the rice in the hopper.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0036] like Figure 1As shown, the automatic rice beating machine of this embodiment includes a frame 1, on which a hopper 2 is installed, and a breaking mechanism 3 is installed in the hopper 2; a mounting plate 11 is fixed to the frame 1, and an upper cylinder 4 is connected to the mounting plate 11, and the upper cylinder 4 is located at the lower side of the hopper 2; a lifting mechanism 5 is also installed on the frame 1, and the output end of the lifting mechanism 5 is connected to a lifting plate 51, and the lifting plate 51 is connected to a lower cylinder 6, and the lower cylinder 6 is located at the lower side of the upper cylinder 4; a cardboard driving mechanism 7 is installed on both the mounting plate 11 and the lifting plate 51, and the output end of the cardboard driving mechanism 7 on the mounting plate 11 is connected to an upper cardboard 71, and the output end of the cardboard driving mechanism 7 on the lifting plate 51 is connected to a lower cardboard 72, the upper cardboard 71 is located at the lower end of the upper cylinder 4, and the lower cardboard 72 is located at the lower end of the lower cylinder 6, and a clearance gap 61 is provided on the lower cylinder 6, and the upper cardboard 71 is sleeved in the clearance gap 61.

[0037] The rice is poured into the hopper 2, and the breaking mechanism 3 breaks the rice fully. The broken rice falls into the lower tube 6 through the upper tube 4, and then the upper clamping plate 71 is closed and the upper tube 4 is driven up by the lifting mechanism 5, and the rice in the lower tube 6 is compressed and shaped. Then the lower clamping plate 72 is opened, and the shaped and quantitative rice is put into the container. Since the upper clamping plate 71 is sleeved in the clearance notch 61 of the lower tube 6, when the lower tube 6 rises, the upper clamping plate 71 will not interfere with the lower tube 6.

[0038] The purpose of driving the lower drum 6 upward to press and shape the rice is to ensure that the rice maintains its shape after falling onto the plate. If the amount of pressed rice is small, it is easy to control the degree of pressing and will not cause the rice to become hardened. After the loose rice enters the lower drum 6, it is pressed again to avoid the situation where the rice in the hopper 2 is directly pressed and the whole rice becomes hardened.

[0039] The scattering mechanism 3 of the present invention can scatter the rice sufficiently so that the rice can smoothly fall into the upper tube 4 and the lower tube 6. After the rice falls into the lower tube 6, the upper clamping plate 71 is closed so that the rice is quantitatively controlled. When the lower tube 6 is driven to rise, the rice is compressed and shaped, ensuring that the rice will not scatter when it is served. The rice slicing efficiency can be improved by using the present invention to slicing rice.

[0040] Specifically, Figure 2 As shown, the scattering mechanism 3 includes a plurality of scattering roller mounting shafts 31, the rotating shafts of the scattering roller mounting shafts 31 are connected to the hopper 2, a plurality of scattering rollers 32 are mounted on the scattering roller mounting shafts 31, the plurality of scattering roller mounting shafts 31 are connected to each other through gears 33, and a motor is connected to one of the scattering roller mounting shafts 31 through a connecting shaft. The motor drives one of the scattering roller mounting shafts 31 to rotate, and the plurality of scattering roller mounting shafts 31 are connected to each other through gears 33. When the scattering roller mounting shafts 31 rotate, the scattering rollers 32 thereon can fully scatter the agglomerated rice, ensuring that the rice can smoothly fall into the upper barrel 4 and the lower barrel 6.

[0041] likeFigure 3 As shown, a slideway 12 is fixed on the frame 1, a slide rail 21 is fixed on the hopper 2, the slide rail 21 is sleeved in the slideway 12, and a locking screw 13 for locking the slide rail 21 is threadedly connected to the frame 1. The slide rail 21 on the hopper 2 can slide in the slideway 12, which is convenient for adjusting the position of the hopper and for disassembling and assembling the hopper.

[0042] Specifically, Figures 4 to 7 As shown, the upper cylinder 4 includes a conical cylinder 41, which is located at the lower side of the hopper 2, a blanking cylinder 42 is fixed at the lower end of the conical cylinder 41, and the lower cylinder 6 is sleeved outside the blanking cylinder 42; a leak-proof cylinder 43 is fixed on the blanking cylinder 42, and the leak-proof cylinder 43 is sleeved outside the lower cylinder 6. The leak-proof cylinder 43 is located at the lower side of the upper clamping plate 71, and when the lower cylinder 6 is lowered, the leak-proof cylinder 43 blocks the clearance gap 61 of the lower cylinder 6. The upper end of the conical cylinder 41 is open to prevent the rice from spilling to the outside during the process of falling into the upper cylinder 4. The lower cylinder 6 is sleeved outside the blanking cylinder 42, so that the rice can accurately fall from the upper cylinder 4 into the lower cylinder 6. When the lower cylinder 6 is lowered, the leak-proof cylinder 43 blocks the clearance gap 61 of the lower cylinder 6 to prevent the rice from leaking out of the clearance gap 61.

[0043] Furthermore, the lower cylinder 6 is in a conical shape, and the lower end opening of the lower cylinder 6 is larger than the upper end opening of the lower cylinder 6. When the lower cylinder 6 rises, the upper clamping plate 71 presses the rice, and the adhesion between the rice and the lower cylinder 6 increases. The lower cylinder 6 of the present invention has a certain taper, so when the lower clamping plate 72 is opened, the rice can fall smoothly under the action of gravity, avoiding the situation where the rice cannot be discharged due to the rice being pressed.

[0044] like Figure 8 and Figure 9 As shown, the card drive mechanism 7 includes a steering engine 73 and a slide 74 installed on the mounting plate 11 or the lifting plate 51, the output end of the steering engine 73 is connected to a cantilever 75, and the other end of the cantilever 75 is rotatably connected to a guide block 76; a slider 77 is sleeved in the slide 74, the slider 77 is sleeved in the slide 74, a guide groove 78 is fixed on the slider 77, the guide block 76 is sleeved in the guide groove 78, and the upper card 71 or the lower card 72 is connected to one end of the slider 77. The steering engine 73 drives the cantilever 75 to rotate, and the cantilever 75 pushes the guide groove 78 to move through the guide block 76. Since the guide groove 78 is fixed to the slider 77 and the slider 77 is sleeved in the slide 74, the slider 77 can move linearly in the slide 74. Under the push of the slider 77, the upper card 71 or the lower card 72 can move in or out accurately, so that the lower end of the upper tube 4 or the lower tube 6 can be closed or opened. The movement of the upper card plate 71 and the lower card plate 72 is automatically controlled by the card plate driving mechanism 7, so that automatic control is convenient. A bearing is installed on the guide block 76 to ensure that the relative sliding between the guide block 76 and the guide groove 78 is more stable.

[0045] The number of the upper clamping plates 71 and the lower clamping plates 72 is two each. Each upper clamping plate 71 or lower clamping plate 72 is connected to a clamping plate driving mechanism 7. The shapes of the upper clamping plates 71 and the lower clamping plates 72 are both semi-circular. The two clamping plate driving mechanisms 7 synchronously control the two upper clamping plates 71. When the two upper clamping plates 71 are joined together, the lower end of the upper cylinder 4 is closed. The two clamping plate driving mechanisms 7 synchronously control the two lower clamping plates 72. When the two lower clamping plates 72 are joined together, the lower end of the lower cylinder 6 is closed.

[0046] As Figure 4 and Figure 5 shown, for the convenience of disassembling and assembling the upper cylinder 4, a limiting sliding groove 111 is fixed on the mounting plate 11. Two semi-circular clamping rings 112 are sleeved outside the upper cylinder 4. Clamping blocks are arranged on the semi-circular clamping rings 112. The clamping blocks are sleeved in the limiting sliding groove 111. The two semi-circular clamping rings 112 are connected by a locking pull rod 113. The two semi-circular clamping rings 112 can be locked by the locking pull rod 113, so that the upper cylinder 4 is fixed. When it is necessary to disassemble the upper cylinder 4 for cleaning, only the locking pull rod 113 needs to be loosened, and the operation is convenient.

[0047] As Figure 10 shown, for the convenience of disassembling and assembling the lower cylinder 6, a limiting block 511 is fixed on the lifting plate 51. A limiting groove is arranged on the limiting block 511. A limiting convex block 62 is arranged on the lower cylinder 6. The limiting convex block 62 is sleeved in the limiting groove. A locking tongue 512 for clamping the limiting convex block 62 is connected to the limiting groove. The limiting groove on the limiting block 511 can limit the limiting convex block 62 of the lower cylinder 6, and then the limiting convex block 62 is locked by the locking tongue 512, so as to reliably fix the lower cylinder 6. When it is necessary to disassemble the lower cylinder 6 for cleaning, only the locking tongue 512 needs to be turned open and the lower cylinder 6 is lowered, then the lower cylinder 6 can be taken out smoothly.

[0048] Specifically, as Figure 4 shown, the lifting mechanism 5 includes a lifting mounting plate 52. The lifting mounting plate 52 is mounted on the frame 1. A linear motor 53 is mounted on the lifting mounting plate 52. The output end of the linear motor 53 is connected to the lifting plate 51. A collar 521 is fixed on the lifting mounting plate 52. A guide rod 513 is sleeved in the collar 521. One end of the guide rod 513 is fixed on the lifting plate 51. The linear motor 53 can drive the lifting plate 51 to accurately lift and lower, so that the lower cylinder 6 can accurately lift and lower along with the lifting plate 51. The guide rod 513 can guide the lifting plate 51 to ensure that the lifting plate 51 moves more smoothly during the movement.

[0049] Working principle:

[0050] Pour the rice into the hopper 2, and the motor drives the scattering roller mounting shaft 31 to rotate, so that the scattering roller 32 scatters the rice fully. Open the upper card plate 71, close the lower card plate 72, and lower the lower cylinder 6, and the scattered rice falls into the lower cylinder 6 through the upper cylinder 4. At this time, the leak-proof cylinder 43 blocks the clearance gap 61 of the lower cylinder 6 to prevent the rice from leaking out of the clearance gap 61. Close the upper card plate 71 again and drive the upper cylinder 4 to rise, so that the rice in the lower cylinder 6 is compressed and shaped. Open the lower card plate 72 again, and the shaped and quantitative rice is put into the container.

[0051] The present invention is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the protection scope of the present invention.
