Description

Technical Field

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

[0002] Rice packaging and palletizing is a key process in grain processing and logistics, aiming to efficiently and safely stack packaged rice into pallets for easy storage, transportation, and subsequent management.

[0003] In standard operations, rice is typically stacked with 4-6 bags per layer, with a stacking height usually controlled at around 1.5 meters. However, current rice bag palletizing equipment on the market suffers from a significant efficiency shortcoming—these devices are often equipped with only a single clamping station. This means that during palletizing operations, the robotic arm needs to clamp and hold the bag 4 to 6 times to complete each layer, severely limiting overall operational efficiency and failing to meet the urgent demand for high efficiency in modern production. Utility Model Content

[0004] The purpose of this invention is to provide a rice packaging bag palletizing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rice packaging bag palletizing device, comprising a base, a palletizing robot arm disposed at the upper end of the base, and a clamping mechanism for clamping the packaging bags disposed at the lower end of the palletizing robot arm. The clamping mechanism includes a connecting shaft, a fixed frame, a central fixed plate, a slide rail, a mounting rod, and two side clamping plates. A connecting shaft is disposed at one end of the palletizing robot arm, a fixed frame is fixedly disposed at the lower end of the connecting shaft, a central fixed plate is fixedly disposed at the lower middle part of the fixed frame, slide rails are fixedly disposed at the four corners of the lower surface of the fixed frame, and a mounting rod is movably disposed on the outer surface of the slide rail via a slider, with two side clamping plates fixedly disposed at one end of the mounting rod.

[0006] Preferably, a transmission mechanism for driving the clamping plates on both sides to clamp is provided at the lower middle part of the fixed frame. The transmission mechanism includes a gear and a rack. The gear is movably arranged at the lower middle part of the fixed frame through a rotating shaft. The rack is fixedly arranged on the surface of the clamping plates on both sides. The rack and the gear mesh with each other. Through the rotation of the gear of the transmission mechanism and the rack, the clamping plates on both sides can be driven to perform the clamping work simultaneously.

[0007] Preferably, a functional compartment is fixedly installed at the upper middle part of the fixed frame, a worm gear reducer is fixedly installed inside the functional compartment, an electric motor is fixedly installed on one side of the worm gear reducer, and the power output shaft of the electric motor is connected to the rotating shaft of the gear through the worm gear reducer. The electric motor drives the worm gear reducer to drive the gear to rotate.

[0008] Preferably, the lower end of the fixed frame is provided with rollers that are movably mounted on both sides of the gear via a rotating shaft. The surface of the rollers is in contact with the surface of the rack, and the rollers can limit the rack to ensure that the rack can mesh with the gear.

[0009] Preferably, two conveyor belts are provided on both sides of the lower end of the fixed frame. The two conveyor belts are located at the lower end of the fixed frame and can be used to transport the packaging bags that need to be palletized.

[0010] Preferably, the surfaces of the central fixing plate and the two side clamping plates are provided with rubber pads. The rubber pads can increase the friction of the surfaces of the central fixing plate and the two side clamping plates, thereby making it easier to clamp the packaging bag.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model is equipped with a dual-station clamping device, which can clamp two bags at a time when facing palletizing operations. With dual conveyor belts feeding the material, the robotic arm only needs to repeat two to three times to complete one layer of stacking work, which can greatly improve work efficiency.

[0013] 2. When clamping, the packaging bag can be simultaneously transported to the lower end of the fixed frame via two conveyor belts. Then, the gear can be driven to rotate by the motor and worm gear reducer. The gear can drive the rack, so that the two clamping plates can move closer to each other and finally clamp the packaging bag. In this way, the two clamping plates are linked together, making control convenient and operation easy. Attached Figure Description

The clamping mechanism includes a connecting shaft 3, a fixed frame 4, a central fixed plate 5, a slide rail 6, a mounting rod 7, and two side clamping plates 8. The palletizing robot 2 is provided with a connecting shaft 3 at one end, and a fixed frame 4 is fixedly provided at the lower end of the connecting shaft 3. A central fixed plate 5 is fixedly provided at the lower middle part of the fixed frame 4. Slide rails 6 are fixedly provided at the four corners of the lower surface of the fixed frame 4. The mounting rod 7 is movably provided on the outer surface of the slide rail 6 through a slider, and two side clamping plates 8 are fixedly provided at one end of the mounting rod 7.

[0022] The fixed frame 4 is provided with a transmission mechanism at the lower middle part for driving the clamping plates 8 on both sides to clamp. The transmission mechanism includes a gear 9 and a rack 10. The gear 9 is movably arranged at the lower middle part of the fixed frame 4 through a rotating shaft. The rack 10 is fixedly arranged on the surface of the clamping plates 8 on both sides. The rack 10 and the gear 9 mesh with each other. By rotating the gear 9 of the transmission mechanism in coordination with the rack 10, the clamping plates 8 on both sides can be driven to perform the clamping work simultaneously.

[0023] A functional compartment 11 is fixedly installed in the middle of the upper end of the fixed frame 4. A worm gear reducer 12 is fixedly installed inside the functional compartment 11. An electric motor 13 is fixedly installed on one side of the worm gear reducer 12. The power output shaft of the electric motor 13 is connected to the shaft of the gear 9 through the worm gear reducer 12. The worm gear reducer 12 driven by the electric motor 13 can drive the gear 9 to rotate.

[0024] The lower end of the fixed frame 4 is provided with rollers 14 that are movably mounted on the gear 9 via a rotating shaft on both sides. The surface of the rollers 14 is in contact with the surface of the rack 10. The rollers 14 can limit the rack 10 to ensure that the rack 10 can mesh with the gear 9.

[0025] Two conveyor belts 15 are provided on both sides of the lower end of the fixed frame 4. The two conveyor belts 15 are located at the lower end of the fixed frame 4. The packaging bags that need to be palletized can be transported through the two conveyor belts 15.

[0026] Rubber pads are provided on the surfaces of the central fixing plate 5 and the two side clamping plates 8. The rubber pads can increase the friction of the surfaces of the central fixing plate 5 and the two side clamping plates 8, thereby making it easier to clamp the packaging bag.

[0027] Working principle: This device is equipped with dual-station clamping, which allows for clamping two bags at a time during palletizing operations. The dual conveyor belts 15 feed the bags, and the robotic arm only needs to repeat the process two to three times to complete one layer of stacking, thus greatly improving work efficiency. During clamping, the packaging bags can be simultaneously transported to the lower end of the fixed frame 4 via the two conveyor belts 15. Then, the motor 13 and the worm gear reducer 12 drive the gear 9 to rotate, which in turn drives the rack 10, causing the two clamping plates to move closer together and finally clamp the packaging bags. In this way, the two clamping plates are linked together, making control convenient and operation easy.
