Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a rice packaging device capable of effectively reducing the temperature of rice. Background Technique

[0002] Rice is the seed of paddy rice, which is made into food after processes such as cleaning, hulling, milling, and finished product finishing. When rice is processed, it needs to be packaged, so a packaging device is required.

[0003] When rice is packaged, it is usually stored in a rice hopper. Since the temperature of rice will rise after multiple processes, it is not easy to dissipate heat when stored in the hopper. When the rice is directly poured into the packaging bag and then sealed and packed, the hot air will condense into water droplets in the packaging bag under high temperature, which easily causes the rice to get damp and mildew, thus affecting the quality. Therefore, we propose a rice packaging device capable of effectively reducing the temperature of rice. Content of the Utility Model

[0004] The purpose of the utility model is to provide a rice packaging device capable of effectively reducing the temperature of rice, so as to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A rice packaging device capable of effectively reducing the temperature of rice, including a packaging table, a weighing device, a cooling box, a rice hopper, and a sealing machine. The weighing device is installed on one side of the top of the packaging table. The sealing machines are installed on both sides of the top of the weighing device, and a cylinder is installed on the outer wall of the sealing machine. The output end of the cylinder penetrates through the sealing machine and is installed with a clamping plate, and a heat-sealing block is installed on one side of the clamping plate. The cooling box is arranged on one side of the packaging table. A first conveyor belt is installed on the top of the cooling box, and a second conveyor belt is installed inside the cooling box below the first conveyor belt. And a third conveyor belt is installed at the bottom of the cooling box below the second conveyor belt. Exhaust pipes are installed inside the cooling box above the first conveyor belt, the second conveyor belt, and the third conveyor belt. One end of the exhaust pipe extends to the outside of the cooling box. A feeding hopper is installed on one side of the bottom of the cooling box, and a feeding pipe is installed at the bottom end of the feeding hopper. The rice hopper is installed on the top of the cooling box, and a feeding pipe is installed at the bottom end of the rice hopper, and the feeding pipe extends above the first conveyor belt. An induced draft fan is arranged on one side of the cooling box, and an induced draft air pipe is installed at the input end of the induced draft fan, and the induced draft air pipe is communicated with the exhaust pipe.

[0006] Preferably, a conveyor belt is installed on the top of the packaging table on one side of the weighing device, and a conveyor motor is installed at one end of the conveyor belt. The output end of the conveyor motor is fixedly connected to the driving end of the conveyor belt.

[0007] Preferably, a laser sensor is installed on the inner wall of the bottom of the sealing machine. When the laser sensor senses the packaging bag, the conveyor motor pauses working.

[0008] Preferably, a feeding valve is installed at the connection between the feeding pipe and the feeding hopper.

[0009] Preferably, a material guiding inclined plane is arranged at the bottom of the cooling box.

[0010] Preferably, ventilation openings are arranged on one outer side wall of the cooling box, so that external air is supplemented into the cooling box through the ventilation openings, and the high-temperature gas inside the cooling box is discharged, making the cooling effect obvious.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The rice inside the rice hopper falls onto the surface of the first conveyor belt inside the cooling box through the feeding pipe. The conveyor motor drives the first conveyor belt, the second conveyor belt and the third conveyor belt to operate, so that the first conveyor belt, the second conveyor belt and the third conveyor belt sequentially convey the rice. During this process, the induced draft fan operates, and the induced draft pipe extracts the heat of the rice through the air extraction pipe above the first conveyor belt, the second conveyor belt and the third conveyor belt.

[0025] The rice hopper 6 is installed at the top of the cooling box 3, and a feed pipe 13 is installed at the bottom end of the rice hopper 6. The feed pipe 13 extends above the first conveyor belt 7;

[0026] Specifically, the rice inside the rice hopper 6 falls onto the surface of the first conveyor belt 7 inside the cooling box 3 through the feed pipe 13.

The conveyor belt 11 conveys the packaging bag between the sealing machines 10. When the laser sensor 24 senses the packaging bag, the conveyor motor 12 pauses. At this time, the air cylinder 25 drives the clamping plate 22 to clamp the opening of the packaging bag, and the heat sealing block 23 heat-seals the opening of the packaging bag. After sealing, the conveyor motor 12 continues to drive the conveyor belt 11 to operate, and the staff can take away the packaged rice, completing the packaging work of the rice.
