Description

Technical Field

[0001] This utility model relates to the field of conveyor roller technology, specifically a conveyor roller for a roller conveyor. Background Technology

[0002] In industrial production and logistics, traditional manual conveying methods suffer from high labor costs, low efficiency, and susceptibility to errors. Conveyor rollers, through their rotation, automate the transport of goods, significantly improving production line efficiency and reducing manual intervention. Conveyor rollers can precisely deliver components to each workstation, ensuring production continuity; in logistics sorting centers, conveyor rollers work in conjunction with automated equipment to achieve rapid sorting and transportation of goods.

[0003] In existing technologies, most conveyor rollers are integrated structures. If they are damaged after long-term use, the entire conveyor roller structure must be replaced, which is wasteful and increases costs.

[0004] To address the aforementioned issues, we propose a conveyor roller for a roller conveyor. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 This utility model provides a technical solution: a conveying roller for a roller conveyor, including a main shaft 1 and multiple replaceable sleeve rollers 2. The replaceable sleeve rollers 2 are detachably connected to the outer circumferential side of the main shaft 1. Each replaceable sleeve roller 2 includes a sleeve roller 21, an insert rod 22, and a positioning block 23. One end of the sleeve roller 21 is provided with the positioning block 23 for connecting to the main shaft 1. The inner side of the sleeve roller 21 abuts against the outer circumferential side of the main shaft 1. The inner side of the sleeve roller 21 is provided with the insert rod 22. The outer circumferential side of the main shaft 1 is provided with a slot for inserting the insert rod 22. The sides of the multiple sleeve rollers 21 abut against the sides of adjacent sleeve rollers 21.

[0026] Both the positioning block 23 and the insertion rod 22 are made of hard rubber material, which can deform within a certain range without affecting the positioning and insertion. In addition, the outer surface of the rubber material has high friction, which can prevent the sleeve roller 21 from sliding unnecessarily.

[0027] Furthermore, the main shaft 1 includes a shaft body 11 and a bearing seat 12. One end of the shaft body 11 is connected to the bearing seat 12. The bearing seat 12 has multiple mating grooves on its connecting side with the shaft body 11. The positioning block 23 is inserted into the mating groove of the bearing seat 12. The outer circumferential side of the shaft body 11 has multiple slots, and the insertion rod 22 is inserted into the slot of the shaft body 11. Furthermore, the angle between the slots on the main shaft 1 and the outer circumferential side of the main shaft 1 is no greater than 45 degrees. The inclined design of the slots on the main shaft 1 is intended to address the centrifugal force caused by the rotating conveyor rollers, which causes the sleeve roller 21 to separate outwards. If inserted vertically, there is no way to prevent the sleeve roller 21 from separating outwards. The inclined design of the slots on the main shaft 1 can avoid this problem to a certain extent. Additionally, the sidewalls of the slots on the main shaft 1 are designed with structures to increase friction; rubber pads or cat tongue cloth can be selected.

[0028] Furthermore, the end of the sleeve roller 21 away from the positioning block 23 is provided with a positioning piece 24, and a positioning ring 3 is sleeved on the shaft 11. The positioning ring 3 is slidably connected to the outer circumferential side of the shaft 11, and the inner circumferential side of the positioning ring 3 is provided with a thread. The positioning ring 3 is threadedly connected to the positioning piece 24.

[0029] The positioning piece 24 is made of a thinner alloy. When the positioning ring 3 is tightened with the positioning piece 24, the positioning piece 24 can undergo a certain deformation to better fit the outer circumferential side of the shaft 11.

[0030] Furthermore, a pull ring 25 is provided at the end of the sleeve roller 21 away from the positioning block 23. The ring body of the pull ring 25 is rotatably connected to the fixed part, and the outermost height of the ring body can be higher than the outer circumferential side of the sleeve roller 21. This is because the position of the pull ring 25 is generally located inside the outer conveyor frame and does not contact the conveying component. In addition, there will always be a certain amount of space inside the conveyor frame to avoid chain friction.

[0031] Furthermore, the pull ring 25 is designed to facilitate workers to disassemble the sleeve roller 21 more quickly without having to manually pry open the edge.

[0032] Furthermore, one end of the main shaft 1 is provided with a sprocket assembly 4. The sprocket assembly 4 is used to connect an external chain, thereby realizing the transmission between multiple conveying rollers and connecting with different drive mechanisms.

[0033] Furthermore, a sealing strip is provided between one of the rollers 21 and the other roller 21.

[0034] Working principle:

[0035] When the sleeve roller 21 is damaged, first screw the positioning ring 3 in the loosening direction, then slide the positioning ring 3 close to the sprocket assembly 4. At this time, the sleeve roller 21 is pulled up by the pull ring 25, the insert rod 22 is disengaged from the slot of the shaft body 11, and the positioning block 23 is disengaged from the mating groove of the shaft seat 12.

[0036] The newly replaced roller 21 is inserted into the slot of the shaft 11 through the insertion rod 22, the positioning block 23 is inserted into the mating groove of the shaft seat 12, the positioning ring 3 is slid toward the positioning piece 24, and the positioning ring 3 and the positioning piece 24 are tightened to complete the replacement process.
