Description

Technical Field

[0001] This utility model belongs to the technical field of rice packaging machines, and specifically relates to a rice packaging and temporary storage device. Background Technology

[0002] A rice packaging machine is a device used to package rice, and it is widely used in the catering industry.

[0003] Patent application CN202322034528.8 discloses a vehicle-mounted staple food portioning and packaging machine. The machine's interior includes a rice conveying module connected to the bottom of the rice input module's rice outlet. The rice input module breaks up any rice clumps inside, allowing the rice to fall through the outlet into the conveying module. The conveying module pushes the loose rice into a quantitative feeding module. The quantitative feeding module weighs the rice in a measuring bin using a weighing sensor, and a feeding cylinder pushes the bin along a slide rail mechanism, feeding the rice into a packaging and forming unit inside the cabinet. The user feeds cooked rice, along with a tray, into the rice input module, then through the conveying module to the quantitative feeding module. After weighing, the portioned rice is automatically packaged and output. This effectively realizes the complex process of quickly and quantitatively packaging processed cooked rice in a mobile environment. It features a compact structure, powerful functionality, and requires minimal manual operation.

[0004] Before packaging rice, it needs to be weighed. If the weighed rice is directly added to the rice bag, the weighing unit must both weigh the rice and accurately fill it into the bag. When the next rice bag is ready to be filled, it may be necessary to wait for the weighing unit to arrive. Adding a rice storage unit allows the weighed rice to be poured directly into the storage unit. After the rice bag is opened, the storage unit accurately fills the bag with rice, avoiding the waiting time for the weighing unit and improving rice packaging efficiency. Current technology lacks such a rice storage unit. Utility Model Content

[0005] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a rice packaging and temporary storage device.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A rice packaging and temporary storage device includes a rice storage hopper and a temporary storage lifting cylinder fixed on a frame. A lifting conical hopper is provided below the rice storage hopper. The lifting conical hopper is connected to the piston rod of the temporary storage lifting cylinder. Opening and closing plates are rotatably connected to both sides of the lower opening of the lifting conical hopper. An opening and closing drive mechanism for driving the two opening and closing plates to open and close is connected to the lifting conical hopper.

[0008] The temporary storage lifting cylinder raises the lifting conical hopper, sealing the gap between it and the rice temporary storage hopper. At this point, the weighed rice is added to the rice temporary storage hopper for temporary storage. Once the rice bag is opened, the temporary storage lifting cylinder lowers the lifting conical hopper, increasing the space for the rice to fall into it and reducing the risk of rice blockage. The opening and closing drive mechanism then opens two opening plates, allowing the rice in the lifting conical hopper to accurately fall into the rice bag, achieving accurate bagging.

[0009] This invention allows for the temporary storage of pre-weighed rice. The opening and closing mechanism only drives the two opening plates to open after the rice bag at the bottom is opened, preventing rice from spilling. By temporarily storing the weighed rice in this invention, the weighing unit can perform the next round of weighing while the rice is being filled into the rice bag through the temporary storage device, ensuring the continuous operation of the entire rice packaging machine.

[0010] In a preferred embodiment of this invention, the opening and closing drive mechanism includes an opening and closing cylinder mounted on a lifting conical bucket. A drive rod is fixed to the piston rod of the opening and closing cylinder, and both ends of the drive rod are rotatably connected to opening and closing connecting rods. A swing rod is fixed to the opening and closing plate, and the other end of the swing rod is rotatably connected to the opening and closing connecting rods. The opening and closing cylinder drives the two opening and closing connecting rods to move via the drive rod, and the opening and closing connecting rods drive the opening and closing plate to open via the swing rod. After the two opening and closing plates open, the rice falls into the rice bag.

[0011] As a preferred embodiment of this utility model, the end of the swing rod away from the connecting plate is fixed with an opening and closing pivot, and the other end of the opening and closing pivot is sleeved on the end of the opening and closing connecting rod away from the drive rod.

[0012] As a preferred embodiment of this utility model, the horizontal cross-section of the opening and closing plate is arc-shaped, and the lower end of the opening and closing plate is provided with a bevel. The arc-shaped opening and closing plate can increase the enclosed area, and the gap between the two arc-shaped opening and closing plates can be minimized as much as possible after they are closed.

[0013] As a preferred embodiment of this utility model, the bottom of the lifting conical hopper is fixed with two side baffles, which are located on one side of the gap between the two opening and closing plates. The side baffles can cover the gap between the two opening and closing plates, preventing rice from spilling.

[0014] In a preferred embodiment of this invention, a plurality of dispersing rollers rotate inside the rice storage hopper. Each dispersing roller has dispersing teeth, and adjacent dispersing rollers are connected by gear transmission. A dispersing drive mechanism is also installed on the rice storage hopper, and the output end of the drive mechanism is connected to one of the dispersing rollers. The drive mechanism drives one of the dispersing rollers to rotate, and adjacent dispersing rollers are connected by gear transmission. Thus, when adjacent dispersing rollers rotate in opposite directions, the rice in the rice storage hopper is fully dispersed, allowing the rice to completely fall into the rice bag.

[0015] In a preferred embodiment of this utility model, the disintegration drive mechanism includes a disintegration motor, the output end of which is connected to a disintegration reducer, and the output end of the disintegration reducer is connected to one of the disintegration rollers. After the disintegration motor starts, it drives the disintegration reducer to operate, and the disintegration reducer drives one of the disintegration rollers to rotate.

[0016] As a preferred embodiment of this utility model, the dispersing teeth are triangular in shape, and several dispersing teeth on adjacent dispersing rollers are staggered. The staggered arrangement of the dispersing teeth prevents them from crushing the rice when dispersing it.

[0017] In a preferred embodiment of this invention, the lifting conical hopper is provided with two supporting baffles, which are arranged opposite to each other, and the rice storage hopper is positioned between the two supporting baffles. The supporting baffles can shield the two sides of the rice storage hopper to prevent rice from spilling.

[0018] As a preferred embodiment of this utility model, the bottom of the rice storage hopper is provided with two guide plates, which are fitted inside the lifting conical hopper. The lower ends of the guide plates are inclined inward, and the guide plates are located on one side of the gap between the two supporting baffles. The two guide plates are staggered from the two supporting baffles, so that the two guide plates can block the other two sides, and the rice will not spill when the lifting conical hopper rises or falls.

[0019] The beneficial effects of this utility model are as follows:

[0020] This invention allows for the temporary storage of pre-weighed rice. The opening and closing mechanism only drives the two opening plates to open after the rice bag at the bottom is opened, preventing rice from spilling. By temporarily storing the weighed rice in this invention, the weighing unit can perform the next round of weighing while the rice is being filled into the rice bag through the temporary storage device, ensuring the continuous operation of the entire rice packaging machine.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] 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 to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0029] like Figures 1-5 As shown, the rice packaging and temporary storage device of this embodiment includes a rice storage hopper 1 fixed on the frame and a temporary storage lifting cylinder 2. A lifting conical hopper 3 is provided below the rice storage hopper 1. The lifting conical hopper 3 is connected to the piston rod of the temporary storage lifting cylinder 2. Opening and closing plates 4 are rotatably connected to both sides of the lower opening of the lifting conical hopper 3. An opening and closing drive mechanism 5 for driving the two opening and closing plates 4 to open and close is connected to the lifting conical hopper 3.

[0030] The temporary storage lifting cylinder 2 raises the lifting conical hopper 3, sealing the gap between the lifting conical hopper 3 and the rice temporary storage hopper 1. At this point, the weighed rice is added to the rice temporary storage hopper 1 for temporary storage. After the rice bag is opened, the temporary storage lifting cylinder 2 lowers the lifting conical hopper 3, increasing the space for the rice to fall into it and reducing the risk of rice blockage. The opening and closing drive mechanism 5 drives the two opening and closing plates 4 to open, allowing the rice in the lifting conical hopper 3 to accurately fall into the rice bag, achieving accurate bagging.

[0031] This invention allows for the temporary storage of weighed rice. The opening and closing mechanism 5 only drives the two opening and closing plates 4 to open after the rice bag at the bottom is opened, preventing rice from spilling. By temporarily storing the weighed rice in this invention, the weighing unit can perform the next round of weighing while the rice is being filled into the rice bag through the temporary storage device, ensuring the continuous operation of the entire rice packaging machine.

[0032] Specifically, the opening and closing drive mechanism 5 includes an opening and closing cylinder 51 mounted on the lifting conical bucket 3. A drive rod 52 is fixed to the piston rod of the opening and closing cylinder 51, and both ends of the drive rod 52 are rotatably connected to opening and closing connecting rods 53. A swing rod 41 is fixed to the opening and closing plate 4, and the other end of the swing rod 41 is rotatably connected to the opening and closing connecting rods 53. The opening and closing cylinder 51 drives the two opening and closing connecting rods 53 to move via the drive rod 52, and the opening and closing connecting rods 53 drive the opening and closing plate 4 to open via the swing rod 41. After the two opening and closing plates 4 open, the rice falls into the rice bag.

[0033] The swing rod 41 is fixed to an opening and closing pivot 42 at one end away from the connecting plate 4, and the other end of the opening and closing pivot 42 is sleeved on the end of the opening and closing connecting rod 53 away from the driving rod 52.

[0034] The horizontal cross-section of the hinge plate 4 is arc-shaped, and the lower end of the hinge plate 4 is beveled. The arc-shaped hinge plate 4 can increase the enclosed area, and the gap between the two arc-shaped hinge plates 4 can be minimized when they are closed.

[0035] The bottom of the lifting conical hopper 3 is fixed with two side baffles 31, which are located on one side of the gap between the two opening and closing plates 4. The side baffles 31 can cover the gap between the two opening and closing plates 4 to prevent rice from spilling.

[0036] Furthermore, the rice storage hopper 1 contains several dispersing rollers 6 that rotate within it. Each dispersing roller 6 has dispersing teeth 61, and adjacent dispersing rollers 6 are connected by gears 62. The rice storage hopper 1 is also equipped with a dispersing drive mechanism 7, the output of which is connected to one of the dispersing rollers 6. The dispersing drive mechanism 7 drives one of the dispersing rollers 6 to rotate, and adjacent dispersing rollers 6 are connected by gears 62. Thus, when adjacent dispersing rollers 6 rotate in opposite directions, the rice in the rice storage hopper 1 is thoroughly dispersed, allowing the rice to fall completely into the rice bag.

[0037] Specifically, the dispersing drive mechanism 7 includes a dispersing motor 71, the output end of which is connected to a dispersing reducer 72, and the output end of the dispersing reducer 72 is connected to one of the dispersing rollers 6. After the dispersing motor 71 starts, it drives the dispersing reducer 72 to operate, and the dispersing reducer 72 drives one of the dispersing rollers 6 to rotate.

[0038] The scooping teeth 61 are triangular in shape, and several scooping teeth 61 on adjacent scooping rollers 6 are staggered. The scooping teeth 61 are staggered so that they do not crush the rice when scooping it.

[0039] The lifting conical hopper 3 is equipped with two supporting baffles 32, which are arranged opposite to each other. The rice storage hopper 1 is positioned between the two supporting baffles 32. The supporting baffles 32 can shield the two sides of the rice storage hopper 1 to prevent rice from spilling.

[0040] The bottom of the rice storage hopper 1 is provided with two guide plates 11, which are fitted into the lifting conical hopper 3. The lower end of the guide plate 11 is inclined inward, and the guide plate 11 is located on one side of the gap between the two supporting baffles 32. The two guide plates 11 are staggered from the two supporting baffles 32, so that the two guide plates 11 can block the other two sides, and the rice will not spill when the lifting conical hopper 3 is raised or lowered.

[0041] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model.
