Description

Technical Field

[0001] The invention relates to the technical field of logistics roller conveying line equipment, in particular to a logistics roller conveying line. Background Art

[0002] The roller conveyor line is commonly used for logistics conveying of goods, which is convenient for conveying goods to the required location. The invention patent with patent application number CN202010492737.5 discloses a logistics roller conveyor line. The movable spring plate and the adjusting pressure piece cooperate to drive the push block to move, and the position of the items is adjusted in real time. The items are then protected by the anti-collision soft plate, so that the items can be stably conveyed inside the movable groove. The protective baffle is driven by the tension adjustment piece to limit the position to prevent the protective baffle from tipping outward due to the collision of the items. The fragile and deformable products are efficiently protected to improve the conveying effect of the items. The movable screw is fixed and clamped on the sprocket, and the sleeve plate and the clamping assembly are sleeved together to fix the sprocket. The clamp is fixed in the position of use and driven by the guide sleeve The card parts adjust the distance between the rollers so that the distance between the rollers conforms to the volume of smaller objects, prevent smaller objects from being stuck between the rollers, ensure the operating state of the equipment, and improve the working efficiency of the equipment. According to the technical scheme disclosed by the card parts, when the existing logistics roller conveyor line equipment is in use, on the one hand, when it is occasionally necessary to transport heavier goods, it is easy to crush the rollers, which is not conducive to ensuring the safety of the roller conveyor line. On the other hand, when the downward pressure of the rollers is used to ensure the safety of the transmission through the support rollers, it is easy to cause up and down shaking when the goods are being transported, which is not conducive to ensuring the stability of the goods transmission. On the other hand, when heavy objects are sent out from the roller conveyor line, the rollers will rebound quickly, which is not conducive to ensuring the subsequent transmission safety of lighter goods.

[0016] 2. When the logistics roller conveyor line is in use, the motor drives the chain to rotate through the sprocket, and the chain drives all the main rollers to rotate through the sprocket. The goods are conveyed on the top of the main roller. At the same time, the auxiliary rollers are used to ensure the support strength of the goods. The main rollers and auxiliary rollers are fixed by support plates. The light weight of the main and auxiliary rollers is used to reduce transmission energy consumption and save construction materials. The pin in the guide rod is stuck on the inner side of the bayonet under the elastic force of spring two, thereby preventing the support plate and the guide rod from shaking up and down through spring one, thereby ensuring the stability of the goods transported on the top of the main and auxiliary rollers.

[0017] 3.

The inner side of the Tesla valve 21 and the top of the sleeve 18 are both filled with hydraulic oil. The sleeve 18 is located at the bottom of the guide rod 12. The sleeve 18 corresponds to the guide rod 12 one by one. The support legs 2 are welded to the bottom of the bracket 1. The support legs 2 are evenly distributed on the bracket 1. A card slot 10 is opened on the inner side of the bracket 1. The support plate 9 is stuck on the inner side of the card slot 10. The top of the support plate 9 is stuck on the inner wall of the top of the card slot 10. When the support plate 9 moves downward, the guide rod 12 transports the hydraulic oil at the bottom of the card slot 10 to the inner side of the sleeve 18 through the Tesla valve 21. The piston 19 in the sleeve 18 moves downward, and the spring 20 and the spring 9 are used to release the hydraulic oil. Spring 13 cushions the downward movement of the support plate 9. When heavier goods are moved out from the top of the logistics roller conveyor line, spring three 20 squeezes the piston 19 upward, and spring one 13 squeezes the support plate 9 on the guide rod 12 upward, so that the hydraulic oil flows upward through the Tesla valve 21.

[0026] In this embodiment, the two ends of the main roller 3 are mounted on the inner side of the support plate 9 through bearings, an inner groove 22 is opened on the inner side of the support plate 9, a support block 23 is clamped on the inner side of the inner groove 22, the top of the support block 23 is clamped on the inner wall of the top of the inner groove 22, and the bottom of the support block 23 is connected to the inner wall of the bottom of the inner groove 22 through a spring 24, and the two ends of the auxiliary roller 4 are mounted on the inner side of the support block 23 through bearings, the top of the guide rod 12 is welded to the bottom of the support plate 9, and the guide rod 12 is welded to the bottom of the support plate 9. The bottom end is stuck in the inner side of the bottom of the card slot 10, the bottom end of the guide rod 12 is connected to the inner wall of the bottom of the card slot 10 through a spring 13, the outer side of the guide rod 12 is sleeved with a sealing ring, and the sealing ring is sealed and stuck on the inner wall of the card slot 10, the inner side of the bracket 1 is provided with a bayonet 15, the inner side of the guide rod 12 is provided with a pin hole, and the pin hole is located at the top of the sealing ring, one end of the bayonet pin 16 is stuck in the inner side of the pin hole, and one end of the bayonet pin 16 is connected to the inner side of the pin hole through a spring 2 17. The other end of the bayonet 16 passes through the pin hole and extends to the inner side of the bayonet 15. The other end of the bayonet 16 is a hemisphere, and the center of the hemisphere is located on the inner side of the guide rod 12. When the cargo is heavy, the force of the cargo pressing the support rod 9 downward through the main roller 3 and the auxiliary roller 4 is greater than the clamping force of the bayonet 16 on the bayonet 15 under the elastic force of the spring 17, so that the bayonet 16 is squeezed to the inner side of the guide rod 12, and the support plate 9 and the guide rod 12 compress the spring 13 and move downward. The main roller 3 moves until the bottom of the main roller 3 is clamped on the top of the support roller 14. If the auxiliary roller 4 is still subjected to a large pressure from the goods at this time, the two sides of the auxiliary roller 4 will press the support blocks 23 downward against the spring four 24, thereby causing the auxiliary roller 4 to move downward, reducing the pressure of the goods on the auxiliary roller 4. At the same time, the bottom of the main roller 3 is supported by the support roller 14, thereby effectively avoiding deformation of the main roller 3 and the auxiliary roller 4, ensuring the safety of the main roller 3 and the auxiliary roller 4, being able to adapt to the transmission of heavier goods, and improving the adaptability of the equipment.

When in use, the motor 5 drives the chain 8 to rotate through the sprocket 7, and the chain 8 drives all the main rollers 3 to rotate through the sprocket 7. The goods are conveyed on the top of the main roller 3. At the same time, the auxiliary roller 4 is used to ensure the support strength of the goods. The main roller 3 and the auxiliary roller 4 are both fixed by the support plate 9. The light weight of the main roller 3 and the auxiliary roller 4 is used to reduce the transmission energy consumption and save construction materials. The pin 16 in the guide rod 12 is stuck on the inner side of the bayonet 15 under the elastic force of the spring 2 17, thereby preventing the support plate 9 and the guide rod 12 from shaking up and down through the spring 13, thereby ensuring the stability of the goods transported on the top of the main roller 3 and the auxiliary roller 4.

[0028] The logistics roller conveyor line provides power to all electrical equipment through an external power supply. When in use, the motor 5 drives the chain 8 to rotate through the sprocket 7, and the chain 8 drives all the main rollers 3 to rotate through the sprocket 7. The goods are conveyed on the top of the main roller 3. At the same time, the auxiliary roller 4 is used to ensure the support strength of the goods.

When the goods are heavy, the force of the goods pressing the support rod 9 downward through the main roller 3 and the auxiliary roller 4 is greater than the clamping force of the bayonet 16 on the bayonet 15 under the elastic force of the spring 2 17, so that the bayonet 16 is squeezed to the inside of the guide rod 12, and the support plate 9 and the guide rod 12 compress the spring 13 and move downward until the bottom of the main roller 3 is clamped on the top of the support roller 14. If the auxiliary roller 4 is still under a large pressure from the goods at this time, the two sides of the auxiliary roller 4 will squeeze the support block 23 downward against the spring 4 24, thereby making the auxiliary roller 4 move downward, reducing the pressure of the goods on the auxiliary roller 4, and at the same time, the bottom of the main roller 3 is supported by the support roller 14, thereby effectively avoiding the deformation of the main roller 3 and the auxiliary roller 4, ensuring the safety of the main roller 3 and the auxiliary roller 4, and being able to adapt to the transmission of heavier goods, improving the adaptability of the equipment. When the support plate 9 moves downward, the guide rod 12 transports the hydraulic oil at the bottom of the slot 10 to the inner side of the sleeve 18 through the Tesla valve 21, and the piston 19 in the sleeve 18 moves downward, and the downward movement of the support plate 9 is buffered by the spring three 20 and the spring one 13 When heavier goods are moved out from the top of the logistics roller conveyor line, spring three 20 squeezes the piston 19 upward, and spring one 13 squeezes the support plate 9 on the guide rod 12 upward, so that the hydraulic oil flows upward through the Tesla valve 21.
