Description

Technical Field

[0001] This utility model relates to the field of supply chain transportation equipment technology, specifically to a shock-absorbing conveying device for supply chain transportation. Background Technology

[0002] In the supply chain transportation process, conveyor systems are the core equipment connecting warehousing, sorting, and distribution, and their operational stability directly affects the integrity rate of goods.

[0003] However, existing shock-absorbing structures for supply chain transportation conveyor systems mostly use a single spring or rubber pad as the shock-absorbing element, which can only achieve basic vertical buffering and cannot cope with multi-directional vibrations such as horizontal swaying and tilting impacts common during transportation. At the same time, the shock-absorbing strength of traditional devices is fixed, and the shock-absorbing effect will decrease significantly when the weight of the goods changes, which can easily lead to damage to fragile items. Moreover, most devices have an integrated structure, and the entire device needs to be disassembled and repaired after the shock-absorbing element is damaged, resulting in high maintenance costs and poor adaptability. Therefore, we propose a shock-absorbing conveyor system for supply chain transportation. Utility Model Content

They cannot cope with multi-directional vibrations such as horizontal swaying and tilting impacts that are common during transportation. At the same time, the shock-absorbing strength of traditional devices is fixed. When the weight of the goods changes, the shock-absorbing effect will decrease significantly, which will easily lead to damage to fragile items. Moreover, most devices have an integrated structure, and the whole device needs to be disassembled and repaired after the shock-absorbing element is damaged, resulting in high maintenance costs and poor adaptability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A shock-absorbing conveying device for supply chain transportation includes a support base, a conveying frame, and a conveyor belt. Fixed seats are fixedly installed at both ends of the top of multiple support bases. Support seats are slidably mounted on the top of multiple fixed seats.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1.

The universal ball seat adapts to the vibration direction, the bidirectional damping rod attenuates the transmission of vibration in multiple directions, the shock-absorbing airbag provides vertical buffering, and the rubber buffer layer, metal mesh damping layer and silicone bump layer of the side baffle form a three-level lateral protection, completely solving the problem of cargo tipping and lateral collision damage.

[0014] 2. This utility model, through an adaptive system of pressure sensor, controller, micro air pump and electromagnetic pressure relief valve, can dynamically match the weight of the goods without manual intervention. For heavy goods, the airbag provides high-pressure support to avoid insufficient shock absorption that could cause the goods to bounce and break. For light goods, the airbag provides low-pressure buffering to avoid excessive shock absorption that could cause fluctuations in the conveying speed. The real-time feedback from the pressure sensor can respond to local pressure changes caused by the offset of the goods during transportation, ensuring that the shock absorption effect remains stable. Compared with traditional fixed-parameter shock absorption structures, the integrity rate of the goods is improved. Attached Figure Description

Mounting plates 9 are provided at both ends of both sides of the conveyor belt 3.

[0021] This utility model discloses a shock-absorbing conveying device for supply chain transportation. Two fixed plates 11 are fixedly installed at both ends of one side of the two supporting bases 1. A bidirectional lead screw 12 is rotatably provided between the opposite ends of the two fixed plates 11 on one side. The bottoms of the two mounting plates 9 on one side are threadedly connected to the two ends of the bidirectional lead screw 12. A limiting rod 13 is fixedly installed between the opposite ends of the two fixed plates 11 on the other side. The bottoms of the two mounting plates 9 on the other side are slidably connected to the two ends of the limiting rod 13, facilitating the conveying of goods of different widths.

[0022] This utility model discloses a shock-absorbing conveying device for supply chain transportation. Each of the multiple fixed seats 4 has a shock-absorbing airbag 14 fixedly installed inside. The top of each shock-absorbing airbag 14 is tightly fitted to the bottom of each of the multiple bearing seats 5. Bidirectional damping rods 15 are fixedly installed inside the fixed seats 4 located on both sides of the multiple shock-absorbing airbags 14. The two ends of the multiple bidirectional damping rods 15 are fixedly connected to the bottom of the multiple bearing seats 5 and the bottom of the inner side of the multiple fixed seats 4, respectively, so as to facilitate the adjustment of the inflation volume of the shock-absorbing airbags 14 according to the weight of the goods.

[0023] This utility model discloses a shock-absorbing conveying device for supply chain transportation. Each of the multiple fixed seats 4 has a miniature air pump 16 fixedly installed on one side. One end of each of the multiple miniature air pumps 16 is fixedly connected to one side of each of the multiple shock-absorbing airbags 14. Each of the multiple shock-absorbing airbags 14 has an electromagnetic pressure relief valve 17 through one side of its bottom, which facilitates the control of the size of the shock-absorbing airbags 14.

[0024] This utility model discloses a shock-absorbing conveying device for supply chain transportation. Each of the two side baffles 10 has a rubber buffer layer 18, a metal mesh damping layer 19, and a silicone bump layer 20 on one opposite end surface. The two rubber buffer layers 18 are fixedly connected to one end surface of the two side baffles 10, and the two metal mesh damping layers 19 are located between the two rubber buffer layers 18 and the two silicone bump layers 20, respectively, to prevent the goods from tipping over or being damaged by lateral collision.

[0025] This utility model discloses a shock-absorbing conveying device for supply chain transportation. A motor 21 is fixedly installed on the surface of the fixed plate 11 at one end. The output end of the motor 21 is fixedly connected to one end of the bidirectional lead screw 12, which facilitates the adjustment of the distance between the two side baffles 10.

[0026] This utility model discloses a shock-absorbing conveying device for supply chain transportation. A controller 22 is fixedly installed on the surface of the conveying frame 2. The controller 22 is electrically connected to multiple pressure sensors 8, multiple micro air pumps 16, multiple electromagnetic pressure relief valves 17 and motor 21, thereby improving the automation level of the device.

[0027] In use, when conveying goods of different widths, the controller 22 sends a command to start the motor 21. The output of the motor 21 drives the bidirectional lead screw 12 to rotate. Since the bottom of the mounting plates 9 on both sides are threaded to both ends of the bidirectional lead screw 12, and the mounting plate 9 on the other side is slidably engaged with the limit rod 13, the rotation of the bidirectional lead screw 12 will drive the mounting plates 9 on both sides to move closer or further away synchronously, thereby driving the side baffles 10 to adjust the spacing until it matches the width of the goods, thus preventing the goods from shifting laterally during transportation. The weight detection and shock absorption parameters are preset. After the goods are placed on the conveyor belt 3, the bottom reinforcing beams 6 of the conveyor frame 2 are... A pressure sensor 8 is installed on the top of the universal ball seat 7 at the corresponding position. The pressure sensor 8 collects the pressure signal of the goods on the conveyor frame 2 in real time and transmits the signal to the controller 22. The controller 22 analyzes the pressure signal according to a preset algorithm. If it is heavy goods, it controls the micro air pump 16 on the corresponding fixed seat 4 to start, inflating the shock-absorbing airbag 14 until the airbag pressure reaches the preset high pressure value to enhance the support rigidity. If it is light goods, it controls the electromagnetic pressure relief valve 17 at the bottom of the shock-absorbing airbag 14 to open, releasing some gas and reducing the air pressure to the preset low pressure value to ensure cushioning flexibility and achieve weight reduction. In the initial matching of shock absorption strength, when encountering vertical bumps during transportation, the shock-absorbing airbag 14 absorbs the vertical impact through its own elastic deformation. At the same time, the bidirectional damping rod 15 suppresses excessive rebound and vibration transmission of the airbag through damping, avoiding resonance. When encountering horizontal swaying or tilting impact, the universal ball seat 7 can adaptively deflect around the top of the bearing seat 5 to adapt to the vibration direction. Combined with the lateral damping force of the bidirectional damping rod 15, it attenuates the vibration energy in the horizontal and tilting directions. If the goods move closer to the side baffle 10 due to swaying, the multi-layer structure inside the side baffle 10 will play its role layer by layer. The rubber buffer layer 18 first passes through... The impact is initially offset by elastic deformation. The metal mesh damping layer 19 further attenuates the impact energy through the stretching and compression of the mesh. The silicone bump layer 20 prevents the goods from sliding by the friction between the bumps and the surface of the goods. At the same time, the elastic deformation of the bumps forms a secondary buffer to avoid hard contact between the goods and the side baffle 10. Real-time adjustment in abnormal situations: If the position of the goods shifts during transportation, causing local pressure changes, the pressure sensor 8 will capture the changes in real time and feed them back to the controller 22. The controller 22 can adjust the air pressure of the shock-absorbing airbag 14 in the corresponding area to ensure that the conveying frame 2 is subjected to balanced force and maintains stable operation.
