Description

Technical Field

[0001] This utility model relates to the field of rollers, specifically to the auxiliary roller of a narrow belt machine in a logistics sorting line. Background Technology

[0002] Narrow belt conveyors are a type of conveyor equipment specifically designed for logistics sorting systems. They are mainly used for the efficient transport and sorting of smaller items, such as parcels, boxes, or bulk materials. Due to their compact structure and high flexibility, narrow belt conveyors are widely used in modern automated warehousing, sorting and distribution centers, and manufacturing facilities. The auxiliary roller of a narrow belt conveyor is a key component used in narrow belt conveyors, mainly for supporting and guiding the operation of the conveyor belt.

[0003] Existing narrow belt conveyors typically have auxiliary rollers consisting of a cylinder, bearings, and a connecting shaft. The cylinder can rotate freely on the connecting shaft via the bearings. However, the bearings are usually fitted tightly onto the connecting shaft, and the inner ring of the bearing is fixed to the surface of the connecting shaft by friction. During use, the bearings and cylinder will experience lateral displacement on the surface of the connecting shaft. Moreover, the cylinder is usually made of stainless steel, and the large number of auxiliary rollers results in high costs, requiring further improvement.

[0004] Therefore, it is necessary to invent the auxiliary roller of the narrow belt machine for logistics sorting line. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a secondary roller for a narrow belt machine in a logistics sorting line, comprising a cylinder body, a connecting shaft, and two cylinder covers. The two cylinder covers are rotatably mounted on the surface of the connecting shaft via a limiting rotation assembly, and the opposite ends of the two cylinder covers are respectively fixed to the two ends of the cylinder body.

[0007] Preferably, the limiting rotation assembly consists of a bearing mounting base and a first bearing. The bearing mounting base is fixed inside the cylinder cover, the inner ring of the first bearing is tightly fitted onto the surface of the connecting shaft, and the outer ring of the first bearing is fixed to the inner wall of the bearing mounting base.

[0008] Preferably, first limiting snap rings are symmetrically fixed on both sides of the surface of the connecting shaft, and the two first limiting snap rings abut against the inner ends of the two first bearings respectively.

[0009] Preferably, the limiting rotation assembly consists of a bearing mounting groove and a second bearing. The bearing mounting groove is located on the outside of the cylinder cover. The inner ring of the second bearing is fitted onto the surface of the connecting shaft, and the outer ring of the second bearing is fixed to the inner wall of the bearing mounting groove.

[0010] Preferably, two second limiting springs are symmetrically fixed on both sides of the surface of the connecting shaft, and the two second limiting springs abut against the outer ends of the two second bearings respectively.

[0011] Preferably, the cylinder cap is ultrasonically welded or spin-welded to the end of the cylinder body.

[0012] Preferably, the cylinder body is made of nylon plastic, and the cylinder cap is made of nylon plastic.

[0013] The beneficial effects of this utility model are:

[0014] 1. By using the combination of the cylinder body, connecting shaft, cylinder cover and limiting rotation component, the cylinder body and cylinder cover can rotate freely on the surface of the connecting shaft, and can also effectively prevent the cylinder body and cylinder cover from shifting laterally on the surface of the connecting shaft, which is beneficial to the stable conveying operation of materials by the narrow belt conveyor;

[0015] 2. By using nylon plastic material for the cylinder body and cylinder cover, the manufacturing cost of the auxiliary roller can be greatly reduced, and the connection between the cylinder body and cylinder cover can be effectively guaranteed by ultrasonic welding or spin welding.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example 1:

[0024] Please refer to the appendix. Figures 1-3 The auxiliary roller of the narrow belt machine for logistics sorting line provided by this utility model includes a cylinder body 1, a connecting shaft 2, and two cylinder covers 3. The two cylinder covers 3 are rotatably mounted on the surface of the connecting shaft 2 through a limiting rotation assembly. The opposite ends of the two cylinder covers 3 are respectively fixed to the two ends of the cylinder body 1. The cylinder body 1 is made of nylon plastic, and the cylinder covers 3 are made of nylon plastic. It should be noted that both the cylinder body 1 and the cylinder covers 3 are preferably made of glass fiber reinforced nylon. Glass fiber reinforced nylon is a plastic obtained by adding a certain amount of glass fiber to nylon resin for reinforcement. Its mechanical strength, rigidity, heat resistance, creep resistance and fatigue strength are greatly improved. The cylinder covers 3 are ultrasonically welded or spin-welded to the end of the cylinder body 1. Specifically, by making the cylinder body 1 and the cylinder covers 3 of nylon plastic, the manufacturing cost of the auxiliary roller can be greatly reduced, and the ultrasonic welding or spin-welding method can effectively ensure a stable connection between the cylinder body 1 and the cylinder covers 3.

[0025] The limiting rotation assembly consists of a bearing mounting base 4 and a first bearing 5. The bearing mounting base 4 is fixed inside the cylinder cover 3. The inner ring of the first bearing 5 is tightly fitted onto the surface of the connecting shaft 2, and the outer ring of the first bearing 5 is fixed to the inner wall of the bearing mounting base 4. Two first limiting snap rings 6 are symmetrically fixed on both sides of the surface of the connecting shaft 2. The two first limiting snap rings 6 abut against the inner ends of the two first bearings 5 ​​respectively. Specifically, under the action of the first bearing 5, the cylinder cover 3 and the cylinder body 1 can rotate freely on the surface of the connecting shaft 2. Moreover, the first limiting snap rings 6 can effectively limit the lateral movement of the first bearing 5 installed inside the cylinder cover 3, thereby effectively preventing the cylinder body 1 and the cylinder cover 3 from shifting laterally on the surface of the connecting shaft 2, which is beneficial to the stable conveying operation of materials by the narrow belt conveyor.

[0026] Example 2:

[0027] Please refer to the appendix. Figures 4-5 The auxiliary roller of the narrow belt conveyor in the logistics sorting line provided by this utility model has a limiting rotation component consisting of a bearing mounting groove 7 and a second bearing 8. The bearing mounting groove 7 is opened on the outside of the cylinder cover 3. The inner ring of the second bearing 8 is tightly fitted onto the surface of the connecting shaft 2, and the outer ring of the second bearing 8 is fixed to the inner wall of the bearing mounting groove 7. Two second limiting springs 9 are symmetrically fixed on both sides of the surface of the connecting shaft 2. The two second limiting springs 9 respectively abut against the outer ends of the two second bearings 8. Specifically, under the action of the second bearings 8, the cylinder cover 3 and the cylinder body 1 can rotate freely on the surface of the connecting shaft 2. Moreover, the second limiting springs 9 can effectively limit the second bearings 8 installed on the outside of the cylinder cover 3 laterally, thereby effectively preventing the cylinder body 1 and the cylinder cover 3 from shifting laterally on the surface of the connecting shaft 2, which is beneficial to the stable conveying operation of materials by the narrow belt conveyor.
