[0012] Furthermore, the frame is provided with multiple mounting bases.

[0013] Furthermore, a guide slope is provided on the inner side of the guide plate.

[0014] Beneficial effects:

[0015] 1. Capable of transporting mixed pallets of different sizes: The conveyor chain unit consists of a first conveyor chain group and a second conveyor chain group, with multiple conveyor chain units arranged in a stepped manner on the frame. This design allows goods of different sizes to be placed on conveyor chain units at different heights for transport, eliminating the need for additional conveyor lines with different conveyor channel sizes based on the pallet size. The guide plate has a guiding ramp on its inner side. When goods are placed, the guiding ramp guides and positions goods of different sizes, ensuring that goods are accurately placed on the conveyor chain. Furthermore, during transport, the guide plate guides the goods, preventing them from shifting, further ensuring the mixed transport of pallets of different sizes. Through this structural design, the equipment can meet the transport needs of goods of different sizes on a single conveyor loop, improving the equipment's versatility and effectively solving the problem of only being able to use a single conveyor loop to transport goods of different sizes due to space constraints and cost budget limitations.

[0016] 2. Power Output (Conveyor Chain) with Vertical Differential Structure: The vertical differential structure of the conveyor chain units enables the equipment to perform multiple conveying functions within a limited space. Multiple conveyor chain units are distributed in a stepped manner, allowing conveyor chain units at different heights to simultaneously transport goods of different sizes, which greatly improves the efficiency of the conveyor line per unit space. Compared to traditional horizontal conveyor structures, the vertical differential structure reduces the horizontal footprint of the conveyor line, optimizing space utilization. The vertical differential structure also makes the conveying process more orderly, with goods of different sizes running on their respective conveyor chain units, reducing mutual interference between goods and improving the stability and reliability of the conveying process.

[0017] 3. Single power source, multiple power outputs: The drive motor in the drive mechanism serves as a single power source, mounted on the frame via a motor bracket. A drive pulley is installed at the output end of the drive motor, connected to a driven pulley on the drive shaft via a transmission belt. The drive shaft is coaxially connected to the drive wheels of the first and second conveyor chain groups. This design allows the power of the drive motor to be transmitted to the drive shaft through the pulley assembly, thereby simultaneously driving multiple conveyor chain units, achieving a single power source matching multiple power outputs. This design simplifies the equipment's power system, reduces the number of power devices, and lowers equipment cost and energy consumption. With only one power source, equipment maintenance and management are also more convenient, reducing operational problems caused by asynchronous or malfunctioning power sources, and improving the overall stability and reliability of the equipment.

Detailed Implementation

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] Example: Figure 1 - Figure 5 As shown, a chain conveyor device with a vertical differential structure includes: a frame 1, on which multiple conveyor chain units 2 are arranged, each conveyor chain unit 2 having a symmetrical plane coinciding with the center line of the frame 1, the multiple conveyor chain units 2 being arranged in a stepped manner on the frame 1; a drive mechanism 3 for driving the multiple conveyor chain units 2 to move simultaneously and a guide plate 4 for guiding the transported goods are provided on the frame 1. Each conveyor chain unit 2 includes: a first conveyor chain group 21 and a second conveyor chain group 22 parallel to the first conveyor chain group 21, the first conveyor chain group 21 and the second conveyor chain group 22 having identical structures. The frame 1 includes: side panels 11, two side panels 11 being connected by multiple crossbeams 12, and the conveyor chain units 2 being mounted on the side panels 11. The side panel 11 includes multiple mounting side plates 111 connected by a connecting plate 112. A cavity 113 is formed between the multiple mounting side plates 111 for mounting the first conveyor chain assembly 21 and the second conveyor chain assembly 22. The first conveyor chain assembly 21 includes chains 211, multiple chains 211 mounted within the cavity 113 via end wheels 212. A drive wheel 213 and a guide wheel 214 for winding the chains 211 around the drive wheel 213 are disposed within the cavity 113. The shaft of the guide wheel 214 is disposed within a slotted hole 215 on the mounting side plate 111 and locked in place by a nut. The driving mechanism 3 includes a drive motor 31, which is mounted on the frame 1 via a motor bracket 32. A drive shaft 33 is mounted on the frame 1. The drive shaft 33, the drive wheel 213 of the first conveyor chain group 21, and the drive wheel 213 of the second conveyor chain group 22 are coaxially connected. The drive motor 31 is connected to the drive shaft 33 via a pulley group 34. The pulley group 34 includes a drive pulley 341, which is mounted on the output end of the drive motor 31. A driven pulley 342 is mounted on the drive shaft 33. The drive pulley 341 and the driven pulley 342 are connected via a transmission belt 343. Multiple mounting bases 5 are provided on the frame 1. A guide slope 6 is provided on the inner side of the guide plate 4.

[0026] The frame 1, serving as the fundamental support structure for the entire equipment, consists of side supports 11 and crossbeams 12. The two side supports 11 are connected by multiple crossbeams 12, providing a stable mounting platform for the conveyor chain unit 2, drive mechanism 3, and other components. Its structural design ensures the overall stability and rigidity of the equipment, enabling it to withstand the weight of goods during transport and various forces generated during operation. This ensures the equipment will not deform or shake during long-term operation, maintaining its normal operation and laying a solid foundation for the functionality of other components.

[0027] The conveyor chain unit 2 includes a first conveyor chain group 21 and a second conveyor chain group 22, which are parallel and have the same structure. The chain 211 of each conveyor chain group is installed in the cavity 113 of the side support 11 via end wheels 212, achieving cyclic movement under the coordinated action of the drive wheel 213 and guide wheel 214. The main function of the conveyor chain unit 2 is to carry and transport goods. In actual operation, goods are placed on the conveyor chain and moved with the chain's movement. Multiple conveyor chain units 2 are arranged in a stepped manner. This vertical differential structure design allows goods of different sizes to be transported on the same equipment by conveyor chain units of different heights, effectively solving the problem of mixed transport of pallets of different sizes and greatly improving the equipment's versatility and practicality.

[0028] The drive mechanism 3 consists of a drive motor 31, a motor bracket 32, a drive shaft 33, and a pulley assembly 34. The drive motor 31 is mounted on the frame 1 via the motor bracket 32, serving as a power source for the entire equipment. When the drive motor 31 operates, its output pulley 341 rotates, driving the driven pulley 342 on the drive shaft 33 via the transmission belt 343, thus causing the drive shaft 33 to rotate. Since the drive shaft 33 is coaxially connected to the drive wheels 213 of the first conveyor chain group 21 and the second conveyor chain group 22, multiple conveyor chain units 2 can move simultaneously. This design of the drive mechanism 3 provides stable and efficient power output, ensuring the continuous and stable operation of the conveyor chain units 2 and guaranteeing that goods can be transported at a predetermined speed and direction. Furthermore, the design of a single drive motor driving multiple conveyor chain units simplifies the equipment's power system and reduces equipment cost and maintenance difficulty.

[0029] Guide plate 4 is installed on frame 1, and guide ramp 6 is provided on its inner side. The main function of guide plate 4 is to guide the transported goods, ensuring that the goods always move in the correct direction during the transportation process and avoiding the goods from deviating or falling. The design of guide ramp 6 allows the goods to make smoother contact with the conveyor chain when entering the conveying area, playing a role in buffering and guiding, further improving the stability and reliability of the goods transportation, and reducing the risk of collision and damage to the goods during the transportation process.

[0030] The side panel 11 consists of multiple mounting side plates 111 connected by a connecting plate 112, forming a cavity 113 between the mounting side plates 111 for mounting the first conveyor chain group 21 and the second conveyor chain group 22. The side panel 11 not only provides mounting positions for the conveyor chain unit 2 but also protects and supports it. Furthermore, its structural design facilitates modular assembly and maintenance of the equipment. When a component malfunctions, the corresponding mounting side plate can be easily disassembled and replaced, improving the maintainability of the equipment.

[0031] Mounting base 5 is installed on the frame 1, primarily serving to support and secure the equipment. By mounting the equipment on mounting base 5, a certain distance is maintained between the equipment and the ground, preventing factors such as ground moisture and dust from affecting the equipment and extending its service life. Furthermore, mounting base 5 also acts as a shock absorber, reducing the impact of vibrations generated during equipment operation on the surrounding environment, and also lowering the risk of loosening or damage to the equipment's components due to vibration.

[0032] The chain 211 in the first conveyor chain group 21 is the component that directly carries the goods. It achieves cyclical motion through the cooperation of the end wheel 212, drive wheel 213, and guide wheel 214, thereby displacing the goods. The drive wheel 213 rotates under the drive mechanism 3, providing power to the chain 211. The shaft of the guide wheel 214 is located in the oblong hole 215 on the mounting side plate 111 and is locked in place by a nut. Its function is to change the direction of movement of the chain 211, allowing the chain 211 to wind around the drive wheel 213 according to a predetermined trajectory, ensuring the smooth operation of the chain 211. By adjusting the position of the guide wheel 214 within the oblong hole 215, the tension of the chain 211 can be adjusted, ensuring that the chain 211 does not become slack or overly tight during operation, further improving the working efficiency and reliability of the conveyor chain group.

[0033] Work process

[0034] Equipment preparation stage: Mounting base 5 secures the equipment firmly in the work area, ensuring a suitable distance between the equipment and the ground to reduce the impact of the ground environment on the equipment and also to provide shock absorption. Connect the equipment power supply; drive motor 31 is in standby mode, awaiting the start command.

[0035] Cargo loading stage: Workers place the goods to be transported onto conveyor chain unit 2. Since conveyor chain unit 2 is arranged in a stepped manner, goods of different sizes can be placed on conveyor chain units at appropriate heights. The guide ramp 6 on the inner side of the guide plate 4 guides the goods smoothly onto the conveyor chain and performs initial positional correction, ensuring the goods are accurately positioned within the carrying area of ​​the conveyor chain, preparing for subsequent transport processes.

[0036] Equipment operation phase: The drive motor 31 is started, and its output shaft drives the drive pulley 341 to rotate. The drive pulley 341 transmits power to the driven pulley 342 via the transmission belt 343, which in turn drives the drive shaft 33 to rotate. Because the drive shaft 33 is coaxially connected to the drive wheels 213 of the first conveyor chain group 21 and the second conveyor chain group 22, the drive wheels 213 rotate accordingly, driving the chain 211 to circulate in cooperation with the end wheel 212 and the guide wheel 214. The goods begin to shift as the conveyor chain moves. During the conveying process, the guide plate 4 guides the goods, preventing them from shifting or falling, ensuring they always move in the correct conveying direction. Simultaneously, the sensors are controlled by the PLC. Real-time monitoring of the conveying distance is omitted in the diagram. When the goods reach the predetermined conveying distance, the sensors feed back a signal to the control system (not described in detail), providing a basis for subsequent unloading or other operations.

[0037] Unloading Phase: When the goods reach the designated unloading position along the conveyor chain, the control system issues a command, which may be to stop the conveyor chain or take other related actions. Workers then remove the goods from the conveyor chain, completing the transport process. Afterward, the equipment can continue transporting the next batch of goods, thus repeating the cycle to achieve continuous goods transport operations.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and all such equivalent transformations fall within the protection scope of the present invention.
