Description

Technical Field

[0001] This utility model relates to the field of rice grain packaging technology, specifically a rice grain packaging machine. Background Technology

[0002] Rice grains, also known as paddy rice, are the fruit of the rice plant. Rice grains are typically white or brown, long and slender in shape, with a smooth surface and a golden-yellow or light brown outer sheath. Each grain contains the germ, endosperm, and bran. Rich in nutrients such as starch, protein, cellulose, vitamins, and minerals, rice is one of the most important staple foods for humans. For many countries, rice is an indispensable staple food in daily life and plays a vital role in food culture. From rice cultivation to harvesting, processing, and consumption, rice grains carry the livelihoods and cherished memories of countless people. A rice grain packaging machine is a device used to package rice or other grains.

[0003] When rice grain packaging machines are in operation, static electricity is generated due to friction between rice grains and metal surfaces. This causes some rice grains to adhere to the inner wall of the packaging machine's storage structure. At the same time, when there is a lot of broken rice or powder inside the packaging machine, it is also easy for it to stick and accumulate. Accumulation may clog the equipment, increase the frequency of downtime for cleaning, and reduce production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a rice grain packaging machine, which has the advantage of turning and mixing the rice grains inside the box to prevent the rice grains from piling up and affecting the packaging efficiency, and solves the problem that rice grains inside the packaging machine are prone to piling up and affecting the packaging.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice grain packaging machine, comprising a box body, a box cover, and a screw sleeve. The box body has fixing grooves on both sides of its top. The box cover has fixing plates installed on both sides of its bottom. A bearing is embedded in the box cover. A fixing frame is fixedly installed on the inner ring of the bearing. Connecting rods are installed on both sides of the fixing frame. Scrapers are installed at opposite ends of the two connecting rods. A lead screw is installed at the bottom of the fixing frame. The screw sleeve engages with the lead screw. Guide plates are installed in a circular array on the outer side of the screw sleeve. Support plates are welded to both sides of the bottom of the box body. Connecting plates are welded to opposite sides of the two support plates. A spring is installed on the top of the connecting plate, and a fixing sleeve is installed on the top of the spring.

[0006] When using a rice grain packaging machine according to this technical solution, two support plates provide support to the box body. Rice grains are added into the box body through the feed pipe, and the box body stores the rice grains. The packaging bag is placed inside the fixed sleeve, and the discharge pipe is opened. The rice grains inside the box body are discharged into the packaging bag through the discharge pipe. As the weight of the packaging bag increases, the spring at the bottom of the fixed sleeve is compressed, and the height of the packaging bag slowly decreases. The servo motor drives the fixed frame to rotate through the transmission structure. The fixed frame drives the scraper to rotate through the connecting rod. The scraper scrapes off the rice grains attached to the inner wall of the box body. The fixed frame drives the lead screw to rotate, and the screw sleeve moves on the rotating lead screw. The screw sleeve drives the guide plate to move up and down. The guide plate flips the rice grains inside the box body. The stirring rods on the sides of the two scrapers mix the rice grains inside the box body.

[0007] Preferably, the two fixing plates are inserted into the two fixing slots, and handles are installed on both sides of the top of the lid. This design uses an insert-type snap-fit ​​structure to achieve quick assembly and disassembly of the lid and the box body, ensuring sealing while reducing assembly difficulty. The double handles are covered with non-slip rubber, and the ergonomic curved grips improve ease of operation, making it particularly suitable for working environments that require frequent opening for cleaning and maintenance.

[0008] Preferably, a feed pipe is embedded in the top of the box lid, and a discharge pipe is embedded in the bottom of the box body. The feed pipe and the discharge pipe are connected to the inside of the box body. Rice grains enter the box body through the feed pipe, the box body stores the rice grains, and the rice grains inside the box body can be discharged from the discharge pipe at the bottom.

[0009] Preferably, a servo motor is installed on the top of the box cover above the fixed frame, and the servo motor transmission structure is fixedly connected to the top of the fixed frame. The servo motor can drive the fixed frame to rotate through the transmission structure, and the fixed frame can drive the lead screw, connecting rod and scraper to rotate.

[0010] Preferably, a positioning rod is installed at the bottom of the fixing frame, and the screw sleeve has a positioning hole through which the positioning rod passes. The positioning rod can effectively restrict the circumferential rotation of the screw sleeve. When the screw sleeve moves on the lead screw, it moves on the positioning rod through the positioning hole, preventing the screw sleeve from shaking and ensuring that the guide plate always maintains the predetermined position when the lead screw is driven.

[0011] Preferably, a baffle is installed at the bottom of the lead screw. The baffle limits the movement of the threaded sleeve, blocking the bottom of the lead screw and restricting the range of movement of the threaded sleeve on the lead screw.

[0012] Preferably, the opposite sides of the two scrapers are in contact with the inner wall of the container, and a stirring rod is installed on the opposite side of each scraper. When the two connecting rods drive the two scrapers to rotate, the two scrapers can scrape off the rice grains adhering to the inner wall of the container. At the same time, the two scrapers will drive the stirring rod to rotate, and the stirring rod will mix and stir the rice grains inside the container.

[0013] Preferably, sliders are installed on both sides of the fixing sleeve, and grooves are formed on the opposite sides of the two support plates. The two sliders and the two grooves are slidably connected. The two sliders limit the fixing sleeve, and when the fixing sleeve is raised or lowered, the two sliders slide within the two grooves to prevent the fixing sleeve from shaking.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, by incorporating a scraper, stirring rods, and a guide plate, allows a servo motor to drive a fixed frame to rotate during the packaging process. The fixed frame, via a connecting rod, drives the scraper to rotate, scraping off rice grains adhering to the inner wall of the box. The fixed frame then drives a lead screw to rotate, causing a screw sleeve to move along the rotating lead screw. This screw sleeve, in turn, moves the guide plate up and down, causing the guide plate to agitate the rice grains inside the box. The stirring rods on the sides of the two scrapers further mix the rice grains inside the box, achieving the desired agitation and mixing effect. This prevents the rice grains from piling up and affecting packaging efficiency. Attached Figure Description
