Description

Technical Field

[0001] This utility model relates to the field of automated sorting technology in logistics, and in particular to a flexible anti-pinch device for a swing arm. Background Technology

[0002] With the widespread application of automated logistics equipment, the volume of parcels handled is growing exponentially. During the swing arm sorting process, thin, soft parcels are easily trapped in the gap between the swing arm and the belt conveyor. Due to the lack of an effective abnormal handling mechanism, such parcels subjected to prolonged pressure will suffer severe damage. Existing solutions rely entirely on manual intervention, which is not only slow to respond but also difficult to handle in real time, ultimately resulting in a high parcel damage rate, seriously affecting sorting quality and operational efficiency. Therefore, we propose a flexible anti-pinch device for swing arms to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a flexible anti-pinch device for swing arms.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A flexible anti-pinch device for a swing arm includes a belt conveyor and a swing arm assembly. The outer wall of the belt conveyor is fixedly connected to the outer wall of the swing arm assembly. A swing arm pivot connector is fixedly connected to the outer wall of the swing arm assembly. A combined joint bearing is fixedly sleeved on the top of the swing arm assembly. A swing arm push plate is fixedly connected to the inner ring of one end of the combined joint bearing. A connecting shaft is rotatably sleeved on one end of the swing arm push plate. The bottom of the connecting shaft is fixedly connected to the top of the swing arm pivot connector. An anti-pinch component is provided at the bottom of the swing arm push plate.

[0006] Preferably, the anti-pinch component includes a PVC board, with the bottom of the swing arm pusher plate fixedly connected to the top of the PVC board. Multiple brushes are fixedly connected to the bottom of the PVC board. By setting the anti-pinch component, the brushes and the belt of the conveyor can be in close contact. This ensures accurate sorting by the swing arm pusher plate and prevents packages from getting stuck between the swing arm pusher plate and the conveyor.

[0007] Preferably, the outer wall of the PVC board has multiple countersunk holes for mounting and fixing to the PVC with existing bolts.

[0008] Preferably, the swing arm pusher is located at the top of the belt conveyor.

[0009] Preferably, the bottom of each of the multiple brushes is in contact with the top of the belt conveyor.

[0010] Compared with the prior art, the advantages of this utility model are:

[0011] This solution's anti-pinch component uses five rows of staggered brushes supported by PVC panels to prevent thin, soft packages from getting stuck and damaged. No manual intervention is required, and the coordinated structure ensures efficient and continuous sorting, making it suitable for high-volume logistics needs. Attached Figure Description

[0020] Depend on Figures 1-4 As shown, a flexible anti-pinch device for a swing arm is disclosed, comprising a belt conveyor 1 and a swing arm assembly 2. The belt conveyor 1 serves as the load-bearing and conveying foundation of the entire device, stably conveying items to be sorted and providing a continuous and orderly material source for the subsequent sorting operation of the swing arm push plate 6, ensuring the continuity of the sorting process. The swing arm assembly 2 is the core driving part of the device to realize the swing sorting action. By cooperating with existing driving equipment (such as a motor) to rotate, it provides power for the movement of the combined joint bearing 4, thereby driving the entire swing arm push plate 6 to complete the swing sorting. It is the key power transmission structure for realizing the sorting function.

[0021] The outer wall of the belt conveyor 1 is fixedly connected to the outer wall of the swing arm assembly 2. The outer wall of the swing arm assembly 2 is fixedly connected to the swing arm pivot connector 3. The top of the swing arm assembly 2 is fixedly fitted with a combined joint bearing 4. The inner ring of one end of the combined joint bearing 4 is fixedly connected to the swing arm push plate 6. The combined joint bearing 4 is composed of two joint bearings and has the flexibility to rotate in multiple directions. One end of it is linked with the swing arm assembly 2, and the other end is rotatably connected to the swing arm push plate 6. This structural design allows the swing arm assembly 2 to flexibly adapt to changes in the motion trajectory when it rotates, ensuring that the swing arm push plate 6 can swing smoothly, effectively reducing jamming during the movement and improving the smoothness of the sorting action.

[0022] The swing arm push plate 6 is located at the top of the belt conveyor 1. One end of the swing arm push plate 6 is rotatably fitted with a connecting shaft 5. The bottom of the connecting shaft 5 is fixedly connected to the top of the swing arm rotating shaft connector 3. The swing arm push plate 6 swings under the cooperation of the combined joint bearing 4 and the connecting shaft 5.

[0023] The bottom of the swing arm push plate 6 is equipped with an anti-pinch component, which includes a PVC plate 7. The PVC plate has a certain rigidity and toughness, is lightweight, and will not add too much load. At the same time, it can provide a stable installation base for the brushes 9. The outer wall of the PVC plate 7 has multiple countersunk holes 8. The bottom of the swing arm push plate 6 is fixedly connected to the top of the PVC plate 7. Multiple brushes 9 are fixedly connected to the bottom of the PVC plate 7. The multiple brushes 9 are arranged in five rows and staggered. The bottom of the multiple brushes 9 are all in contact with the top of the belt conveyor 1.

[0024] The anti-pinch component is designed for the gap between the swing arm push plate 6 and the belt conveyor 1, which can effectively prevent thin soft packages from getting stuck in the gap area, avoid equipment jamming or damage to the items caused by the items getting stuck, and ensure smooth operation of the device.

[0025] Working principle: In use, the swing arm assembly 2 rotates through existing drive equipment such as a motor. The rotation of the motor drives one end of the combined joint bearing 4 to move around the top axis of the motor output shaft. Since the combined joint bearing 4 is composed of two joint bearings, and the other end of the combined joint bearing 4 is rotatably connected to the swing arm push plate 6, and one end of the swing arm push plate 6 rotates around the connecting shaft 5, the combined joint bearing 4 drives the swing arm push plate 6 to swing during rotation, thereby achieving the purpose of sorting (it can be used with existing conventional photoelectric sensors). During sorting, the rotation of the swing arm push plate 6 drives the PVC board 7 and the brush 9 to move. The brush 9 is located in the gap between the swing arm push plate 6 and the belt conveyor 1, which can prevent thin soft packages from being stuck in the gap area.

[0026] All standard parts used in this utility model can be purchased from the market. Irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.
