Description

Technical Field

[0001] This utility model relates to the field of logistics conveying equipment technology, and in particular to a reverse blocking mechanism. Background Technology

[0002] In modern logistics sorting, production line conveying, and warehouse automation systems, the directional flow control of materials or goods is one of the core components. Among these, blocking mechanisms play a crucial role in precisely intercepting or temporarily storing goods at designated locations, ensuring an orderly, efficient, and safe process.

[0003] A search revealed existing blocking mechanisms, such as the blocking mechanism and mobile conveyor disclosed in patent number CN 222714518 U. These blocking mechanisms include multiple sets of telescopic rods arranged side-by-side. The lower ends of each set of telescopic rods are connected via connecting plates, and each connecting plate is connected to a conveyor belt. Each conveyor belt is mounted on a first transmission wheel and a second transmission wheel. The first and second transmission wheels are rotatably mounted on wheel seats and are distributed along the axis of the telescopic rods. The axes of the first and second transmission wheels are perpendicular to the axis of the telescopic rods. Several first or second transmission wheels are concentrically mounted on the same connecting shaft. The two ends of the connecting shaft are rotatably mounted on supports and connected to a primary motor that drives its rotation. This invention uses a primary motor to drive the connecting shaft, causing multiple second transmission wheels to rotate synchronously. This, in turn, drives multiple sets of telescopic shafts to extend and retract synchronously via multiple conveyor belts, effectively meeting the stable blocking requirements of multiple inter-gap conveyor modules, resulting in lower operating costs.

[0004] The aforementioned blocking mechanism is a one-way blocking mechanism. When goods need to pass through in the opposite direction, the mechanism becomes an obstacle, requiring manual intervention, additional lifting / translation mechanisms, or complex control systems (such as cylinder-driven retraction of the baffle) to allow passage. This not only significantly increases system complexity and cost but also reduces the layout flexibility and passage efficiency of the conveyor line, failing to meet the needs of bidirectional flexible conveying in modern intelligent logistics. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a reverse blocking mechanism.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a reverse blocking mechanism, including a conveying assembly, a horizontal plate fixed on the conveying assembly, a bracket on the horizontal plate, a rotating shaft rotatably connected to the bracket, a swing plate on the rotating shaft, a baffle on the lower part of one side of the swing plate, and a first force-bearing part on the upper part of the other side of the swing plate for blocking goods. The bracket includes two bottom plates fixed on the horizontal plate and a top plate connected to the bottom plates by an inclined plate. The length of the baffle is greater than the distance between the two top plates, so that the baffle abuts against one side of the top plate after the first force-bearing part is subjected to force.

[0008] Furthermore, the top of the swing plate is provided with an inclined surface, and the first force-bearing part is provided on the inclined surface.

[0009] Furthermore, the first force-bearing part includes a first force-bearing plate and a first bolt for fixing the first force-bearing plate to the inclined surface.

[0010] Furthermore, the swing plate is provided with a second force-bearing part on the other side of the first force-bearing part. The second force-bearing part includes a base plate fixed on the swing plate and a second force-bearing plate fixed on the base plate by a second bolt.

[0011] Furthermore, a counterweight is provided at the bottom of the swing plate.

[0012] The reverse blocking mechanism proposed in this utility model has the following advantages:

[0013] When the first force-bearing part of this utility model is impacted by goods, the swing plate rotates around the pivot, causing the baffle to abut against the side of the top plate, forming a mechanical self-lock. By utilizing the lever principle, the impact force of the goods is converted into a mechanical locking force between the baffle and the top plate, thus blocking the goods. When the goods impact the second force-bearing plate from the opposite direction, the swing plate rotates in the opposite direction, causing the baffle to detach from the top plate, allowing the goods to pass through the reverse blocking mechanism of this embodiment without obstructing the goods. By setting the first force-bearing part and the second force-bearing part on both sides of the swing plate, intelligent switching between "one-way blocking and reverse release" is achieved, supporting bidirectional conveyor lines without the need for additional mechanisms.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Examples, such as Figures 1-4 As shown, a reverse blocking mechanism includes a conveying assembly 1, which is a chain conveyor (existing technology and will not be described in detail here). It also includes a horizontal plate 2 fixed to the conveying assembly 1, a support 3 mounted on the horizontal plate 2, a rotating shaft 4 rotatably connected to the support 3, a swing plate 5 mounted on the rotating shaft 4, a baffle 6 located on the lower part of one side of the swing plate 5, and a first force-bearing part 7 located on the upper part of the other side of the swing plate 5 for blocking goods. The support 3 includes two base plates 301 fixed to the horizontal plate 2 and a top plate 303 connected to the base plates 301 via an inclined plate 302. Preferably, in this embodiment, there are two supports 3. Furthermore, the inclined plate 302 of the support 3 is symmetrically distributed on the horizontal plate 2 to enhance impact resistance and prevent deformation under force. The length of the baffle 6 is greater than the distance between the two top plates 303, so that the baffle 6 abuts against one side of the top plate 303 after the first force-bearing part 7 is subjected to force. The length of the baffle 6 is greater than the distance between the two top plates 303 to ensure effective contact with the top plate 303 under different working conditions. When the goods hit the first force-bearing part 7, the swing plate 5 rotates around the rotating shaft 4, driving the baffle 6 to abut against the side of the top plate 303, forming a mechanical self-locking. The impact force of the goods is converted into the mechanical locking force between the baffle 6 and the top plate 303 by the lever principle, thereby blocking the goods.

[0020] In an optional embodiment of this utility model, the top of the swing plate 5 is provided with an inclined surface 501. Preferably, the top cross section of the swing plate 5 is trapezoidal, and the top of the inclined surface 501 is inclined towards the direction of the second force-bearing part 8. The angle between the inclined surface 501 and the horizontal plane is 50°-70°. The first force-bearing part 7 is provided on the inclined surface 501. This arrangement can reduce the local pressure of the cargo on the first force-bearing part 7 and extend the service life of the component.

[0021] In an optional embodiment of this utility model, the first force-bearing part 7 includes a first force-bearing plate 701 and a first bolt 702 that fixes the first force-bearing plate 701 to the inclined surface 501. In this embodiment, the first force-bearing plate 701 can be made of nylon material. Nylon material absorbs impact energy and protects the goods and mechanism. The first bolt 702 connects to facilitate quick replacement of the worn first force-bearing plate 701. When the goods come into contact with the first force-bearing plate 701 under the conveying component 1, the swing plate 5 drives the baffle 6 to abut against one side of the top plate 303, thereby blocking the goods.

[0022] In an optional embodiment of this utility model, the swing plate 5 is provided with a second force-receiving part 8 on the other side of the first force-receiving part 7. The second force-receiving part 8 includes a base plate 801 fixed on the swing plate 5 and a second force-receiving plate 803 fixed on the base plate 801 by a second bolt 802. In this embodiment, the second force-receiving plate 803 can be made of nylon material. When the goods hit the second force-receiving plate 803 from the opposite direction, the swing plate 5 rotates in the opposite direction, causing the baffle 6 to detach from the top plate 303, so that the goods can pass through the reverse blocking mechanism of this embodiment without obstructing the goods. By providing the first force-receiving part 7 and the second force-receiving part 8 on both sides of the swing plate 5, the intelligent switching of "one-way blocking and reverse release" is realized, supporting bidirectional conveyor lines without the need for additional mechanisms.

[0023] In an optional embodiment of this utility model, a counterweight 9 is provided at the bottom of the swing plate 5. Preferably, in this embodiment, the counterweight 9 is fixed at the bottom of the swing plate 5. The counterweight 9 provides a downward torque so that the swing plate 5 remains in a vertical initial state when there is no external force.
