Rice packaging and stacking mechanism

Abstract

This utility model discloses a rice packaging and palletizing mechanism, relating to the technical field of rice packaging and palletizing equipment. It includes a conveyor belt with mounting plates fixedly connected to both sides of its upper end. The two mounting plates are symmetrical, and a cylinder is mounted on one side of each mounting plate. The telescopic rods of the two cylinders are fixedly connected to mounting platforms. This utility model conveys bagged rice by placing it on the conveyor belt. When the rice is between two straightening belts, the two cylinders are activated, bringing the two straightening belts closer together. Simultaneously, the motor is activated, causing the straightening belts to drive within the mounting frame. When the surfaces of the straightening belts come into contact with the bagged rice, the friction generated between the belts and the rice agitates the rice, straightening it on the conveyor belt. This ensures the rice is firmly gripped by the palletizing grippers, preventing it from slipping off during handling and transfer, improving palletizing efficiency, and preventing rice from scattering.

Description

Technical Field

[0001] This utility model relates to the technical field of rice packaging and palletizing equipment, specifically to a rice packaging and palletizing mechanism. Background Technology

[0002] Rice packaging is a crucial step in ensuring rice quality, extending shelf life, and facilitating transportation and sales. Rice is typically packaged in woven bags, which are then sealed to achieve proper packaging. However, packaged rice requires storage and transportation, necessitating the use of palletizing mechanisms to improve the efficiency of stacking, storing, and transporting packaged rice, reduce labor costs, and ensure stacking stability and safety. Palletizing mechanisms mainly consist of material conveyor belts, palletizing grippers, gantry drive structures, and control systems.

[0003] Most rice packaging and palletizing mechanisms currently operate by packaging finished rice into bags and placing them on a material conveyor belt. The conveyor belt then transports the rice to the palletizing gripper, which is activated and works in conjunction with the gantry drive structure to achieve palletizing. However, in actual use, the bags of rice may tilt when they reach the palletizing gripper. Due to their irregular shape, the palletizing gripper may not be able to fully fit or firmly hold the rice. During the gripping and transfer process, the rice may slip off the gripper, affecting palletizing efficiency, potentially damaging the equipment, scattering rice, increasing cleanup costs, and making the system inconvenient to use.

[0021] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] This utility model provides a technical solution: such as Figure 1 - Figure 4 As shown, in this embodiment, a rice packaging and palletizing mechanism includes: a conveyor belt 1, with mounting plates 5 fixedly connected to both sides of the upper end of the conveyor belt 1, the two mounting plates 5 being symmetrical to each other, a cylinder 8 being installed on one side of each of the two mounting plates 5, a mounting platform 9 being fixedly connected to the telescopic rods of the two cylinders 8, a mounting frame 10 being provided on one side of each of the two mounting platforms 9, a motor 11 being installed on the upper end of each of the two mounting frames 10, and multiple drive rollers 15 being rotatably connected to the inner walls of each of the two mounting frames 10, the output end of the motor 11 being connected to one side of the drive roller 15 via a shaft coupling, and a straightening belt 12 being drivenly connected to the outer surface of the drive roller 15.

[0024] Bagged rice is placed on conveyor belt 1 for transport. When the rice is between two straightening belts 12, two cylinders 8 are activated to bring the two straightening belts 12 closer together. At the same time, motor 11 is activated, so that the straightening belts 12 are driven within the mounting frame 10. When the surface of the straightening belts 12 comes into contact with the bagged rice, the friction generated between the straightening belts 12 and the rice moves the rice, straightening it on the conveyor belt 1. This ensures that the rice can be firmly clamped by the palletizing gripper 3, preventing the rice from slipping off the palletizing gripper 3 during the grabbing and transfer process, improving the palletizing efficiency of the equipment, and preventing the rice from scattering.

[0025] It is important to note that the infrared detection device 4 detects the distance of the rice using infrared light. When the bagged rice is tilted, the distance increases or decreases. The infrared detection device 4 detects the tilt of the rice on the conveyor belt 1, and the detection data is transmitted to the control box 7. The control box 7 controls two cylinders 8 and two motors 11 to work together to correct the bagged rice.

[0026] like Figure 1 - Figure 4 As shown, a sliding hole is provided through one side of the mounting plate 5, and a guide rod 13 is slidably connected in the sliding hole. One end of the guide rod 13 is fixedly connected to one side of the mounting platform 9. The guide rod 13 is used to limit the sliding direction of the mounting platform 9.

[0027] like Figure 3 and Figure 4 As shown, a T-shaped block 14 is fixedly connected to one side of the mounting bracket 10. The T-shaped block 14 is slidably connected to the inner wall of the mounting platform 9. An extension plate 18 is fixedly connected to the upper end of the mounting bracket 10. A threaded hole is opened through one side of the extension plate 18. A threaded rod 20 is threadedly connected to the inner wall of the threaded hole. A fixing block 17 is rotatably connected to one end of the threaded rod 20. A fixing hole 16 is opened on one side of the mounting platform 9. The fixing block 17 is engaged in the fixing hole 16.

[0028] Through the structural design of T-block 14, fixing hole 16, fixing block 17 and threaded rod 20, rotating threaded rod 20 moves threaded rod 20 along the threaded hole in extension plate 18, pulling fixing block 17, removing fixing block 17 from fixing hole 16, releasing T-block 14 from the mounting platform 9, and then lifting T-block 14 upwards, it is convenient for staff to remove mounting bracket 10 from mounting platform 9 for replacement and maintenance.

[0029] like Figure 4 As shown, the upper end of the T-shaped block 14 is provided with a guide groove 19, and the lower end of the fixing block 17 is slidably connected inside the guide groove 19; the guide groove 19 is used to limit the sliding direction of the fixing block 17; wherein the lower end of the fixing block 17 is fixed with a protrusion, the protrusion slides in the guide groove 19, and the protrusion is the fixed end away from the fixing block 17.

[0030] like Figure 1 As shown, a gantry drive structure 2 is provided on one side of the conveyor belt 1. A palletizing gripper 3 is installed at the output end of the gantry drive structure 2. A palletizing platform 6 is provided on one side of the inner wall of the gantry drive structure 2. The conveying end of the conveyor belt 1 is located inside the gantry drive structure 2. The bagged rice is conveyed into the gantry drive structure 2 by the conveyor belt 1. The gantry drive structure 2 is opened, the position of the palletizing gripper 3 is adjusted, and then the palletizing gripper 3 is opened again to clamp the rice. After clamping, the rice is placed on the palletizing platform 6 for palletizing.

[0031] It should be noted that the gantry drive structure 2 includes a support frame and a drive structure. The drive structure drives the palletizing gripper 3 to move along the XYZ axes of the support frame to achieve material picking and palletizing.

[0032] like Figure 1 and Figure 2 As shown, a control box 7 is installed on one side of the gantry drive structure 2, and an infrared detection device 4 is installed on the upper side of the conveyor belt 1; the infrared detection device 4 is used to detect the tilt of the bagged rice on the conveyor belt 1.

[0033] This utility model provides a rice packaging and palletizing mechanism, the specific working principle of which is as follows:

[0034] When stacking bagged rice, the worker places the bagged rice on the conveyor belt 1, turns on the conveyor belt 1 to transport the rice. When the bagged rice moves to the position of the infrared detection device 4, the infrared detection device 4 detects the tilt of the rice on the conveyor belt 1 and transmits the detection data to the control box 7. The control box 7 controls the cylinder 8 and the motor 11 to work together. When the rice is between the two straightening belts 12, the two cylinders 8 are turned on to bring the two straightening belts 12 closer to each other. At the same time, the motor 11 is turned on so that the straightening belts 12 can move within the mounting frame 10. When the surface of the straightening belt 12 comes into contact with the bagged rice, the friction generated between the straightening belt 12 and the rice moves the rice and straightens it. The straightened rice moves into the gantry drive structure 2, the gantry drive structure 2 is turned on, the position of the stacking gripper 3 is adjusted, and then the stacking gripper 3 is turned on to clamp the rice. After clamping, the rice is placed on the stacking table 6 for stacking.
