Description

Technical Field

[0001] This utility model relates to the field of roller technology, and in particular to an accumulation roller. Background Technology

[0002] Currently in the roller industry, adjustable accumulating rollers are conventional products with built-in bearings in the cylinder body, and the bearing housings are made of stamped steel plates. The friction plates are placed inside the bearing housings. After a period of use, the friction plates will naturally wear down and require necessary replacement and maintenance. However, due to the conventional structure of the accumulating rollers, it is necessary to disassemble a large number of machine parts to remove the roller and replace the new friction plates. This is extremely inconvenient, time-consuming, labor-intensive, and delays production schedules. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figure 1 An accumulating roller includes a mandrel 1 and a cylinder 2 connected to the mandrel 1. In this embodiment, the mandrel 1 and the cylinder 2 can be connected by welding. It also includes...

[0019] The sprocket 3 is located at one end of the spindle 1, and a first bearing 4 is installed inside the sprocket 3. In this embodiment, the sprocket 3 is a double-row adjustable sprocket.

[0020] The connector 5 is fixed on the spindle 1 by the positioning component 6. A friction plate 7 is provided between the connector 5 and the sprocket 3. The two sides of the friction plate 7 are in contact with the connector 5 and the sprocket 3 respectively. A flat surface is machined on one end face of the sprocket 3 to contact the friction plate 7. A flat surface is also machined on one side of the connector 5 to contact the friction plate 7.

[0021] Pressing assembly 8 is used to continuously provide axial pressure to connector 5.

[0022] In an optional embodiment of the present invention, the positioning component 6 includes a countersunk hole 601 formed on one side of the connector 5 and a cylindrical pin 602 disposed in the countersunk hole 601 for fixing the connector 5 to the mandrel 1.

[0023] Torque is generated by the squeezing and friction of the two planes on the friction plate 7. When the equipment operates, the chain drives the sprocket 3, and the provided friction force is converted into torque. It is transmitted to the spindle 1 through the connector 5 and the cylindrical pin 602. The spindle 1 transmits the torque to the cylinder 2, and the tangential force of the cylinder 2 drives the goods to be conveyed forward.

[0024] In an optional embodiment of the present invention, the pressing assembly 8 includes a flat washer 801 sleeved on the spindle 1, a helical compression spring 802 disposed between the flat washer 801 and the connector 5, and a nut 803 screwed to the spindle 1 for pushing the flat washer 801 to compress the helical compression spring 802, wherein the helical compression spring 802 continuously provides axial pressure to the connector 5.

[0025] In an optional embodiment of this utility model, the mandrel 1 is provided with support components 9 at both ends. The support components 9 include a frame plate 901 connected to the mandrel 1, a bearing seat 902 connected to the frame plate 901, and a second bearing 903 mounted on the bearing seat 902. Preferably, the second bearing 903 in this embodiment is a deep groove ball bearing. One end of the bearing seat 902 has a boss that transitions with the hole of the frame plate 901 and is locked by fasteners. The bearing seat 902 is equipped with a deep groove ball bearing. The outer side of the deep groove ball bearing is axially fixed by a type A elastic retaining ring with a hole. This structure with an external bearing seat also facilitates the replacement of the deep groove ball bearing.

[0026] In an optional embodiment of this utility model, a bushing 10 is provided between the bearing housing 902 and the sprocket 3 to separate the bearing housing 902 and the sprocket 3 and to position the sprocket 3.

[0027] In an optional embodiment of this utility model, the number of first bearings 4 is two. Preferably, the first bearing 4 in this embodiment is a contact ball bearing. Since there is a long-term axial force at this location after installation, two angular contact ball bearings are installed inside to ensure the normal service life of the bearing when there is a large axial force. The outer side is axially fixed by a type A elastic retaining ring with a hole.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
