Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a bottom receiving mechanism based on the connection of a fast rolling door of a conveyor. Background Art

[0002] A conveyor is a device used for automated transportation of materials and products in production, warehousing, distribution and other occasions. It is usually composed of a transmission system, conveyor belts, rollers, brackets, etc., and can transport materials and products from one place to another. A fast rolling door is a door that is driven by an electric motor and rolls up and down quickly. It is usually used in places that need to be opened and closed frequently, such as logistics warehouses, cold storage, workshops, production lines, parking lots, etc. The fast rolling door joint serves as a bottom receiving mechanism, which refers to the part of the fast rolling door (also called high-speed door, fast rolling door) that contacts the ground. This component is usually used to provide a stable support when the fast rolling door is closed, ensuring that the lower part of the door curtain remains stable and well sealed during operation, and preventing the door curtain from being blown up by the wind or affected by external forces.

[0003] In existing technologies, some conveyor systems often fail to effectively prevent plastic crates from tipping and sliding during transport, leading to cargo loss, equipment failure, and safety hazards. This problem is particularly prominent in fast-moving production and logistics environments. Without additional anti-tilt devices at the junction of the conveyor and the roll-up door, the tilt and instability of the plastic crates can easily cause them to tip. Therefore, a solution has been proposed, using the conveyor's roll-up door junction as a bottom support mechanism to address this issue. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3The utility model provides an embodiment: based on the fast rolling door joint of the conveyor as the bottom receiving mechanism, it includes a roller conveyor 1. The roller conveyor 1 is the basic transportation part of the entire device. Its overall shape is long and is composed of a solid metal frame. There are mounting positions on both sides of the frame for fixing rollers. The rollers are made of metal material with a smooth surface and can rotate freely. It is used to carry and transport items. The outside of the roller conveyor 1 is fixedly connected with a load-bearing plate 20. The load-bearing plate 20 is a thick flat plate with a rectangular shape. It is made of high-strength alloy steel and has excellent load-bearing capacity, providing a good foundation for subsequent installation of components. Stable support, the top of the load-bearing plate 20 is fixedly connected with a triangle plate 2, which is a triangular metal plate made of stainless steel with a smooth surface and no sharp corners. The internal rotation of the triangle plate 2 is connected to the outside of the cylinder 4, and the internal rotation of the triangle plate 2 is connected to the outside of the telescopic column 5. The inside of the triangle plate 2 is fixedly connected with a fixed block 3, which is a block structure in the shape of a rectangular parallelepiped and made of hard metal material. It is connected to the triangle plate 2 by welding, providing a stable installation foundation for subsequent drive components. The internal rotation of the fixed block 3 is connected to the drive component that provides forward and backward movement force.

[0032] The drive assembly includes a cylinder 4, which is a common power output device. Its outer shell is cylindrical and made of metal with good pressure resistance. The outer rotation of the cylinder 4 is connected to the outside of the fixed block 3. The driving end of the cylinder 4 is fixedly connected to a telescopic column 5. The telescopic column 5 is a cylindrical metal rod with a hard material and a smooth surface. It can perform telescopic movement under the drive of the cylinder 4, and its telescopic direction is along the axial direction of the cylinder 4. The drive assembly is fixedly connected to a U-shaped rotating plate 6. The U-shaped rotating plate 6 is a metal plate with a shape similar to a "U" and is made of high-strength alloy steel. , its opening faces downward, and it has good structural strength and stability. The top of the U-shaped rotating plate 6 is fixedly connected to two connecting columns 9. The connecting column 9 is an elongated cylinder made of metal and is connected to the U-shaped rotating plate 6 by welding, providing a connection point for the installation of subsequent components. The tops of the two connecting columns 9 are fixedly connected to a U-shaped connecting plate 10. The U-shaped connecting plate 10 is a "U"-shaped structure similar to the U-shaped rotating plate 6. It is made of metal and forms a relatively stable overall structure with the U-shaped rotating plate 6 through the connecting columns 9. Its opening faces upward, and the interior of the U-shaped connecting plate 10 is rotatably connected to a rotating roller 11.

[0033] The rotating roller 11 is a cylindrical roller, which is made of a composite structure of a metal core wrapped with wear-resistant and elastic rubber. It has a smooth surface and can rotate freely around its own axis in the U-shaped connecting plate 10. It is used to undertake and guide the movement of objects. The interior of the triangular plate 2 is fixedly connected with multiple limit columns 7. The limit columns 7 are cylinders perpendicular to the triangular plate 2. They are hard and made of metal. Two are evenly distributed on each side of the triangular plate 2. They are used to limit and guide the movement of the U-shaped rotating plate 6. The outside of the limit column 7 is slidably connected to the inside of the U-shaped rotating plate 6. The outside of the U-shaped rotating plate 6 is rotatably connected to the inside of the triangular plate 2. The outside of the limit column 7 is fixedly connected to the limit ring 8. The limit ring 8 is an annular structure made of metal and is installed on the limit column 7 to prevent the U-shaped rotating plate 6 from separating from the limit column 7 during sliding, thereby ensuring the safety and reliability of the entire device.

[0034] Reference Figure 1 、 Figure 4 , the bottom of the roller conveyor 1 is fixedly connected to a protective shell 12, which is an outer shell structure for protecting internal components. It is in the shape of a rectangular parallelepiped and is made of metal material, such as steel plate, with good sealing and protection. The inside of the protective shell 12 is fixedly connected to a motor 13. The motor 13 is a common power output device, whose outer shell is made of metal material and is cylindrical in shape. It has a complex electromagnetic winding and rotor structure inside, which can convert electrical energy into mechanical energy. The driving end of the motor 13 is fixedly connected to a rotating column 14, which is a cylindrical metal shaft perpendicular to the motor 13. The material is hard and made of high-strength alloy steel with a smooth surface. It can stably transmit the torque generated by the motor 13 and rotate around its own axis under the drive of the motor 13. The outside of the rotating column 14 is fixedly connected to a support plate 15. The support plate 15 is a flat rectangular metal plate made of steel plate, which provides a stable support platform for cylinder 2 16 and the structure connected to it. The top of the support plate 15 is fixedly connected to cylinder 2 16.

[0035] Cylinder 2 16 is similar to cylinder 1 4 and is a linear power output device. Its shell is cylindrical and made of metal. It is fixed to the support plate 15 by welding. The driving end of cylinder 2 16 is fixedly connected with telescopic column 2 17. Telescopic column 2 17 is a cylindrical metal rod with a hard material. It performs telescopic movement under the drive of cylinder 2 16. The outside of telescopic column 2 17 is fixedly connected with disc 18. Disc 18 is a circular flat plate made of metal, such as aluminum alloy, with a smooth surface. The disc 18 is fixedly connected to the column 2 17, and can move with the movement of the telescopic column 2 17. The external rotation of the disc 18 is connected to the outside of the roller conveyor 1, and the external rotation of the disc 18 is on the outside of the support plate 15. The outside of the disc 18 is fixedly connected with a well plate 19. The well plate 19 is a metal plate similar to the shape of a "well", which is welded by metal strips. It has a stable structure and is fixed on the disc 18. It can move with the disc 18 and plays a specific role in adjusting the direction of the transported plastic boxes in the device.

[0036] Working Principle: First, cylinder 14 controls the movement of triangular plate 2, which is extended and retracted longitudinally by internal telescopic column 15, thereby adjusting the position of U-shaped rotating plate 6. Guided by limiting columns 7, U-shaped rotating plate 6 can freely rotate around triangular plate 2, ensuring the stability of the plastic crate during transport. The design of limiting columns 7 effectively limits the range of motion of U-shaped rotating plate 6, preventing it from losing control and ensuring the safety of the entire device. When the plastic crate reaches the fast-rolling door, the U-shaped connecting plate 10 and rotating roller 11 work together. The smooth surface and elastic structure of rotating roller 11 guide the plastic crate smoothly through, preventing it from tipping over or sliding.

[0037] At the same time, the plastic boxes are transported on the roller conveyor 1. The roller conveyor 1 serves as the basic transportation part and is responsible for carrying and transporting the plastic boxes. When the plastic boxes pass through the roller conveyor 1, the cylinder 2 16 is started to work, so that the telescopic column 2 17 of the cylinder 2 16 is driven to perform telescopic movement, driving the disc 18 to move up and down to lift the plastic box. Then the motor 13 is started to rotate the rotating column 14, so that the support plate 15 drives the upper structure to rotate, thereby adjusting the direction of the plastic box, which not only optimizes the transportation efficiency, but also improves the flexibility, safety and adaptability of the system. Through the coordinated work of the above-mentioned components, the device can efficiently and stably complete the transportation and direction adjustment of the plastic boxes, ensuring the safety and reliability of the items during transportation.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
