Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and in particular relates to a rice tilting packaging structure with a guide slope. Background Technology

[0002] Rice packaging equipment is specialized machinery used to automatically measure, bag, seal, and output rice as finished products, and is widely used in the grain processing industry. Modern equipment integrates advanced technologies such as PLC control and vacuum extraction (for vacuum packaging), featuring high precision, high efficiency, and a high degree of automation. It effectively ensures the sealing, moisture protection, and shelf life of rice packaging, while significantly improving production efficiency and reducing labor intensity. Common types include back-seal, vacuum, and pre-packaging automatic packaging machines.

[0003] Most rice packaging equipment currently uses conveyor belts to transport rice grains and controls the feeding amount by adjusting the speed of the conveyor belt. When the weighing sensor at the bottom of the bag detects that the weight of the rice grains has reached the set value, the system will issue a stop signal. However, due to the delay between signal transmission, PLC response and mechanical inertia, the conveyor belt cannot stop immediately, which can easily lead to excess material and affect the packaging accuracy.

[0004] To address this issue, we provide a rice tilting packaging structure with a guide ramp to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a rice tilting packaging structure with a guide slope. Through the structural cooperation of the weighing component and the driving component, it solves the problem that existing rice packaging equipment lacks adjustment function and cannot adjust the packaging of overweight rice grains.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a rice tilting packaging structure with a guide slope, comprising a conveyor shell, inside which a belt conveyor is installed, and a rotating shell is provided at the bottom of the conveyor shell; a weighing assembly is provided at the bottom of the conveyor shell, the weighing assembly including a rotating shaft movably connected to one side of the conveyor shell, a rotating frame mounted on the surface of the rotating shaft, and a weighing sensor mounted inside the rotating frame; a drive assembly is provided on one side of the conveyor shell, the drive assembly including a drive motor installed inside the conveyor shell, a first sprocket mounted on the output end of the drive motor, and a second sprocket mounted on the surface of the rotating shaft.

[0008] The present invention is further configured such that the weighing assembly includes an isolation plate installed inside the conveying shell, a guide plate installed on one side of the isolation plate, and a guide groove opened on one side of the guide plate.

[0009] The present invention is further configured such that the guide trough is horizontally aligned with the top of the belt conveyor, the belt conveyor being used to transport rice.

[0010] The present invention is further configured such that a discharge pipe is connected to the bottom of the conveying shell, and the bottom of the discharge pipe is vertically aligned with the rotating shell.

[0011] The present invention is further configured such that a conveying chain is mounted on the surfaces of the first sprocket and the second sprocket, and the surface of the rotating shaft is movably connected to the inner wall of the conveying housing via a bearing.

[0012] The present invention is further configured such that the top of the weighing sensor is fixedly connected to the rotating shell, and a guide plate is fixedly connected inside the rotating shell.

[0013] The present invention is further configured such that a guide rail groove is provided inside the rotating frame, and a slider is slidably connected inside the guide rail groove, with one side of the slider being fixedly connected to the rotating shell.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model, through the setting of the weighing component and the driving component, when the weighing sensor detects that the rice in the rotating shell is overweight, the driving motor can drive the rotating shell to rotate clockwise. With the help of the guide plate and the guide trough, the excess rice is accurately guided back to the belt conveyor for secondary circulation. This closed-loop adjustment mechanism realizes the active correction of overweight materials, avoiding the decrease in packaging accuracy caused by downtime delays in traditional equipment. The rotating shell is stably supported by the rotating shaft and the rotating frame, ensuring stability during the tilting and return process, and improving the accuracy of packaging weighing.

[0016] 2. This utility model optimizes the movement trajectory of materials during the pouring and recirculation process through the sliding cooperation of the guide rail groove and the slider, as well as the unique design of the guide plate. When the rotating shell rotates counterclockwise to discharge materials, the guide plate guides the rice to flow towards the packaging bag. When rotating clockwise to return materials, the guide groove ensures that the rice falls back smoothly onto the conveyor belt, effectively preventing material splashing, blockage, or residue. Through the mechanical structure, it achieves efficient material handling in a limited space, improving the reliability and production efficiency of the equipment.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0026] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0027] Please see Figures 1-6 This utility model is a rice tilting packaging structure with a guide slope, including a conveyor shell 1, a belt conveyor 2 installed inside the conveyor shell 1, and a rotating shell 3 at the bottom of the conveyor shell 1; a weighing assembly 4 is provided at the bottom of the conveyor shell 1, the weighing assembly 4 includes a rotating shaft 401 movably connected to one side of the conveyor shell 1, a rotating frame 402 installed on the surface of the rotating shaft 401, and a weighing sensor 403 installed inside the rotating frame 402; a drive assembly 5 is provided on one side of the conveyor shell 1, the drive assembly 5 includes a drive motor 501 installed inside the conveyor shell 1, a first sprocket 502 installed at the output end of the drive motor 501, and a second sprocket 503 installed on the surface of the rotating shaft 401.

[0028] Further details: The belt conveyor 2 is used for continuous and stable conveying of rice, ensuring that the rice can enter the subsequent weighing stage evenly and orderly. The rotating shell 3 serves as a temporary storage and pouring container for the rice, and can flexibly adjust its tilt angle according to the weighing results to achieve precise discharge. The rotating shaft 401 serves as the rotation axis, which can drive the rotating shell 3 to achieve forward and reverse rotation. The weighing sensor 403 is used to detect the weight change of the rice in the rotating shell 3 and accurately transmit the weight signal to the control system, providing data for weight adjustment. The drive motor 501 serves as the power source, which can provide forward and reverse rotation power to achieve precise angle control of the rotating shell 3. The first sprocket 502 serves as the active transmission component, which can efficiently transmit the power of the drive motor 501 to the second sprocket 503. The second sprocket 503 serves as the driven transmission component, which can receive the power transmitted by the conveyor chain 9 and drive the rotating shaft 401 to rotate synchronously. Example 2

[0029] Please see Figures 1-6 Based on embodiment 1, the weighing assembly 4 further includes an isolation plate 504 installed inside the conveying shell 1, a guide plate 6 installed on one side of the isolation plate 504, and a guide groove 7 opened on one side of the guide plate 6. The guide groove 7 is horizontally aligned with the top of the belt conveyor 2, which is used to convey rice. The bottom of the conveying shell 1 is connected to a discharge pipe 8, and the bottom of the discharge pipe 8 is vertically aligned with the rotating shell 3. A conveying chain 9 is installed on the surface of the first sprocket 502 and the second sprocket 503. The surface of the rotating shaft 401 is movably connected to the inner wall of the conveying shell 1 through a bearing. The top of the weighing sensor 403 is fixedly connected to the rotating shell 3. A guide plate 10 is fixedly connected inside the rotating shell 3. A guide rail groove 11 is opened inside the rotating frame 402. A slider 12 is slidably connected inside the guide rail groove 11, and one side of the slider 12 is fixedly connected to the rotating shell 3.

[0030] Further details: The isolation plate 504 effectively separates the conveying area from the weighing area to prevent rice from splashing during conveying. The guide plate 6 guides overweight rice back to the surface of the belt conveyor 2 smoothly, avoiding material accumulation or blockage. The guide trough 7 serves as a return channel, ensuring that rice grains return smoothly to the belt conveyor 2 along a predetermined path, achieving recycling. The bottom of the conveying shell 1 is connected to a discharge pipe 8, which serves as a transition channel for rice to enter the rotating shell 3 from the conveying shell 1, effectively controlling the material's trajectory. The guide rail groove 11 serves as a sliding guide structure, limiting the movement trajectory of the rotating shell 3 and ensuring that it tilts only in a set direction. A slider 12 is slidably connected inside the guide rail groove 11, serving as a sliding connector that can move smoothly within the guide rail groove 11, reducing shaking and impact during movement.

[0031] The working principle of this utility model is as follows: The operator connects the conveyor shell 1 to the external grain storage equipment. The belt conveyor 2 is started to transport the rice grains inside the storage equipment. Simultaneously, the belt conveyor 2 discharges the rice into the rotating shell 3 via the discharge pipe 8 for temporary storage. At this time, the weighing sensor 403 detects the increased weight inside the rotating shell 3. When the input weight of the rice reaches the set value, a signal is sent to the external controller to stop the belt conveyor 2. Then, the drive motor 501 is started. The drive motor 501, in conjunction with the first sprocket 502, drives the conveyor chain 9 to rotate. The conveyor chain 9, in conjunction with the second sprocket 503, drives the rotating shaft 401 to rotate. The rotating shaft 401, in conjunction with the rotating frame 402, drives the rotating shell 3 to rotate counterclockwise. When the rotating shell 3 rotates counterclockwise around the rotating shaft 401, as... Figure 5 As shown, the tilted surface of the rotating shell 3 is tilted downwards, discharging standard weight of rice grains, which are then collected through the outer packaging bag to complete the weighing and packaging process.

[0032] When rice grains are conveyed by belt conveyor 2 and the weight of the rice grains falling into the rotating shell 3 exceeds the set value, the weighing sensor 403 re-weighs the rice and simultaneously restarts the drive motor 501. The drive motor 501 drives the first sprocket 502 to rotate in the opposite direction. The first sprocket 502, in conjunction with the conveyor chain 9, drives the second sprocket 503 to rotate. The second sprocket 503, in conjunction with the rotating shaft 401 and the rotating frame 402, drives the rotating shell 3 to rotate clockwise. Figure 6 As shown, when the rotating shell 3 rotates upward, it drives the rice grains inside to rotate, and the rice grains are discharged into the conveyor shell 1 through the guide plate 10. The excess rice grains are discharged back to the top of the belt conveyor 2 through the guide plate 6 and the guide groove 7. Then, the drive motor 501 is controlled to drive the rotating shell 3 to reset to the bottom of the discharge pipe 8 for secondary weighing, which can improve the accuracy of the rice packaging weight.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
