Description

Technical Field

[0001] This application relates to the field of rice packaging, and more specifically, to a feeding mechanism and a rice packaging machine. Background Technology

[0002] Rice, also known as paddy rice, is a food made from paddy through processes such as cleaning, hulling, milling, and finishing. Rice is a staple food for people in most parts of China. During the production process, rice needs to be packaged and repackaged so that it can be transported in bags. Repackaging equipment is one of the indispensable pieces of equipment in the rice packaging process.

[0003] When packaging rice, the bag needs to be placed at the bottom of the discharge pipe. At the same time, the top of the bag containing rice needs to be opened and aligned with the bottom of the discharge pipe so that the rice falls into the bag through the discharge pipe. The distance between the top of the bag and the bottom of the discharge pipe should not be too high to prevent the rice from being exposed in the bag during the falling process. For this reason, we have proposed a feeding mechanism and a rice packaging machine. Utility Model Content

[0004] To overcome the above shortcomings, this application provides a feeding mechanism and a rice packaging machine, which aims to improve the problem of fixed discharge pipe height in existing feeding mechanisms.

[0005] In a first aspect, embodiments of this application provide a feeding mechanism, including a platform, a quantitative feeding mechanism installed on the top of the platform, a guide pipe connected to the quantitative feeding mechanism, a bracket installed on the side wall of the platform, and a liftable feeding cylinder installed at the bottom of the bracket, the top of the feeding cylinder corresponding to the outlet end of the guide pipe.

[0006] In one specific implementation, the feeding cylinder includes a lifting ring and a cylindrical bag with openings at both ends. One end of the cylindrical bag is fixedly connected to the bottom of the support, and the other end of the cylindrical bag is fixedly connected to the inner wall of the lifting ring. The lifting ring is fitted onto the cylindrical bag.

[0007] In one specific implementation, a U-shaped block is fixedly installed on the outer wall of the bracket, a threaded rod is rotatably passed through the U-shaped block, a lifting block is threadedly sleeved on the threaded rod, a lifting plate is fixedly connected to the outer wall of the lifting block, and the lifting plate is fixedly connected to the lifting ring.

[0008] In one specific implementation, the support is cylindrical in shape, and a baffle is fixedly installed on its top.

[0009] In one specific implementation, the quantitative discharging mechanism includes a sealing disc installed on the top of the platform and a rotating shaft rotatably connected to the top of the platform. The rotating shaft rotatably passes through the sealing disc, and a box is fixedly installed on its top. Several quantitative tubes are connected to the bottom of the box. The several quantitative tubes are slidably disposed on the sealing disc. A discharge hole is opened on the sealing disc, and the discharge hole is connected to one of the quantitative tubes.

[0010] In one specific implementation, the top of the box is open, the guide tube is fixedly installed at the bottom of the sealing disc, and the guide tube is connected to the discharge hole.

[0011] In one specific implementation, the quantitative discharging mechanism further includes a stepper motor and a hopper. The stepper motor and the hopper are both mounted on the platform. The stepper motor is driven by the rotating shaft. The bottom outlet of the hopper is in contact with the bottom of the box and is covered by one of the quantitative tubes.

[0012] Secondly, this application also provides a rice packaging machine, including the aforementioned feeding mechanism.

[0013] The beneficial effects of this application are as follows: By installing a quantitative discharging mechanism on the platform, with a guide pipe connected to the quantitative discharging mechanism, and a bracket installed on the side wall of the platform, and a feeding cylinder installed at the bottom of the bracket, the quantitative discharging mechanism discharges rice into the feeding cylinder through the guide pipe. A bag for collecting rice is placed at the bottom of the feeding cylinder to achieve the collection of a fixed amount of rice. In addition, the height of the feeding cylinder can be adjusted, so that bags of different heights can be placed at the bottom of the feeding cylinder to facilitate the collection of rice. At the same time, the top of the bag can be close to the bottom of the feeding cylinder to prevent the risk of rice leakage. Attached Figure Description

Detailed Implementation

[0020] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0021] Please see Figures 1-4 This application provides a feeding mechanism, including a platform 10, a quantitative feeding mechanism 20 installed on the top of the platform 10, a guide pipe 30 connected to the quantitative feeding mechanism 20, a bracket 40 installed on the side wall of the platform 10, and a liftable feeding cylinder 50 installed at the bottom of the bracket 40. The top of the feeding cylinder 50 corresponds to the outlet end of the guide pipe 30. Specifically, the quantitative feeding mechanism 20 discharges a quantitative amount of rice into the guide pipe 30. The rice is discharged into the feeding cylinder 50 through the guide pipe 30, thereby placing a bag at the bottom of the feeding cylinder 50 and opening the top of the bag to correspond with the feeding cylinder 50, so that a quantitative amount of rice is poured into the bag. In addition, the height of the feeding cylinder 50 can be adjusted so that bags of different heights can be placed at the bottom of the feeding cylinder 50.

[0022] See Figure 1 The feeding cylinder 50 includes a lifting ring 510 and a cylindrical bag 520 with openings at both ends. One end of the cylindrical bag 520 is fixedly connected to the bottom of the bracket 40, and the other end of the cylindrical bag 520 is fixedly connected to the inner wall of the lifting ring 510. The lifting ring 510 is fitted onto the cylindrical bag 520. When set, the cylindrical bag 520 is flexibly set, so that the lifting ring 510 moves upward and the cylindrical bag 520 can be flipped from the bottom upward, thereby shortening the length of the cylindrical bag 520 and adjusting the height of the discharge port of the cylindrical bag 520, so that bags of different heights can be placed at the bottom of the cylindrical bag 520.

[0023] See Figure 1A U-shaped block 410 is fixedly installed on the outer wall of the bracket 40. A threaded rod 420 is rotatably passed through the U-shaped block 410. A lifting block 430 is threadedly fitted on the threaded rod 420. A lifting plate 440 is fixedly connected to the outer wall of the lifting block 430. The lifting plate 440 is fixedly connected to the lifting ring 510. The bracket 40 is cylindrical and a baffle is fixedly installed on its top. In the specific setting, the lifting plate 440 slides through the U-shaped block 410 so that the U-shaped block 410 limits the lifting plate 440. Then, the threaded rod 420 is rotated so that the lifting block 430 drives the lifting ring 510 to move through the lifting plate 440. A baffle is installed on the top of the bracket 40 and is set away from the guide pipe 30 to prevent rice from being exposed in the bracket 40.

[0024] See Figure 1 and 4 The quantitative discharging mechanism 20 includes a sealing disc 210 mounted on the top of the platform 10, and a rotating shaft 220 rotatably connected to the top of the platform 10. The rotating shaft 220 rotatably passes through the sealing disc 210, and a box 230 is fixedly mounted on its top. Several quantitative tubes 240 are connected to the bottom of the box 230. The quantitative tubes 240 are slidably disposed on the sealing disc 210. The sealing disc 210 has a discharge hole 250, which is connected to one of the quantitative tubes 240. Specifically, the quantitative tubes 240 are distributed in the box 230. At the bottom, several metering tubes 240 slide on the sealing plate 210. When one of the metering tubes 240 slides to correspond with the discharge hole 250, the rice in the metering tube 240 will fall down through the discharge hole 250 to achieve the purpose of discharge. The top of the box body 230 is set with an opening. The guide tube 30 is fixedly installed at the bottom of the sealing plate 210 and is connected to the discharge hole 250. Furthermore, both ends of the metering tube 240 are set with openings. The rice falls into the guide tube 30 through the discharge hole 250 and is then discharged from the guide tube 30.

[0025] See Figure 3 and 4 The quantitative dispensing mechanism 20 also includes a stepper motor 260 and a hopper 270. Both the stepper motor 260 and the hopper 270 are mounted on the platform 10. The stepper motor 260 is driven by the rotating shaft 220. The bottom outlet of the hopper 270 is in contact with the bottom of the box 230 and is covered by one of the quantitative tubes 240. It should be noted that a first spur gear is mounted on the drive shaft of the stepper motor 260, and a second spur gear is mounted on the rotating shaft 220. The first spur gear and the second spur gear are meshed to enable the stepper motor 260 to drive the rotating shaft 220 to rotate, so that the angle of the rotating shaft 220 is fixed each time. Rice is stored in the hopper 270. When one of the quantitative tubes 240 rotates to correspond to the bottom of the hopper 270, the rice in the hopper 270 can fall into the quantitative tube 240, and then the rice fills the quantitative tube 240 to achieve quantitative rice dispensing.

[0026] In this embodiment, the feeding mechanism of this embodiment can be applied to a rice packaging machine.

[0027] When this feeding mechanism and rice packaging machine are in operation: Rice is fed into the hopper 270 through existing equipment. Then, according to the bag height, the length of the tubular bag 520 is adjusted. Specifically, the threaded rod 420 is rotated, which drives the lifting block 430 to move. The lifting block 430 then drives the lifting ring 510 through the lifting plate 440 to adjust the height of the bottom discharge port of the tubular bag 520. After that, the top of the bag is opened and placed at the bottom of the tubular bag 520. The stepper motor 260 is started, which drives the rotating shaft 220 to rotate. The rotating shaft 220 drives the box body 230 to rotate, and the rice in the hopper 270 falls into the metering tube 240. As the box body 230 drives the metering tube 240 to move, the metering tube 240 carrying rice moves to the corresponding discharge hole 250, so that the rice is discharged into the guide tube 30 and finally falls into the bag through the tubular bag 520, realizing the metered rice dispensing.

[0028] It should be noted that the specific model and specifications of the stepper motor 260 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0029] The power supply and operating principle of the stepper motor 260 are clear to those skilled in the art and will not be described in detail here.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
