Description

Technical Field

[0001] This utility model relates to the field of rollers, and in particular to a sealed plastic seat roller. Background Technology

[0002] A roller conveyor is a device that transports goods by rotating multiple sets of rollers. It mainly consists of rollers, a frame, and a drive unit. Goods are placed on the rollers and are transported horizontally by the rotation of the rollers. It is suitable for conveying flat-bottomed or regularly shaped goods such as boxes, pallets, and barrels, and has a strong load-bearing capacity. It can transport goods horizontally, at an angle, or by turning. It is commonly used in logistics warehousing, production lines, packaging workshops, and other scenarios.

[0003] Rollers are typically installed evenly on the material conveying track. However, traditional rollers require bearing housings inside, which necessitates numerous processing steps and welding, and consumes a significant amount of material, resulting in high economic costs.

[0004] In related technologies, application number CN201922260597.4 discloses a fully sealed plastic seat roller, which can maintain an internal vacuum state for a long time, making it difficult for water to enter and eliminating the need for maintenance. When used on a roller conveyor, the roller's light weight and low resistance can improve the conveyor's working efficiency. However, this device only seals the left and right ends of the roller with sealing sleeves. During long-term use, the seal may loosen, reducing its effectiveness and allowing moisture or water to penetrate the roller, thus shortening its service life.

[0005] Therefore, it is necessary to provide a sealed plastic seat roller to solve the above-mentioned technical problems. Utility Model Content

[0023] The sealing assembly 2 includes an extrusion block 21 disposed inside the roller body 1. A deformation sealing ring 22 is disposed to the left of the extrusion block 21 and inside the roller body 1. A main sealing ring 23 is disposed to the left of the deformation sealing ring 22 and inside the roller body 1.

[0024] By rotating the adjusting rod 28, since the circumferential side of the adjusting rod 28 is threaded to the inner side of the fixed cover plate 26, when the adjusting rod 28 is rotated to one side, it will drive the extrusion block 21 to move to the left. The extrusion block 21 then extrudes the deformation sealing ring 22, causing it to deform and expand, thereby improving the sealing effect of the deformation sealing ring 22. Together with the main sealing ring 23, it achieves a high-quality seal on the roller body 1, effectively preventing moisture from entering and ensuring the roller's lifespan.

[0025] A locking ring 24 is provided on the left side of the roller body 1 and at the top of the main sealing ring 23, and sliding columns 25 are arranged in an array that can slide up and down on the inner side of the roller body 1.

[0026] The locking ring 24 can limit the main sealing ring 23 to prevent it from deviating, while the sliding column 25 can fix the fixed cover plate 26 to prevent the fixed cover plate 26 from shifting during subsequent use.

[0027] A fixed cover plate 26 is provided on the left side of the roller body 1 and on the left side of the main sealing ring 23. The inner side of the fixed cover plate 26 is provided with fixed holes for use with the sliding column 25. A fixed spring 27 is provided at the bottom of each sliding column 25.

[0028] During assembly, the extrusion block 21 is first placed inside the roller body 1. Then, the deformation sealing ring 22, the main sealing ring 23, and the locking ring 24 are sequentially fastened to one side of the roller body 1. By pushing the fixing cover plate 26 to the right, the fixing hole part inside it is positioned above the sliding column 25. Under the action of the fixing spring 27, each sliding column 25 is pushed out and abuts against the inside of the fixing hole, thereby fixing the fixing cover plate 26.

[0029] An adjusting rod 28 is rotatably provided on the inner side of the extrusion block 21. The left end of the adjusting rod 28 passes through the inner side of the fixed cover plate 26 and extends to its left side. The peripheral side of the adjusting rod 28 is threadedly connected to the inner side of the fixed cover plate 26.

[0030] After the fixed cover plate 26 is fixed, the left end of the adjusting rod 28 is exposed. By rotating the left end of the adjusting rod 28, the extrusion block 21 can be moved to the left, thereby improving the sealing effect of the deformation sealing ring 22.

[0031] A snap-fit ​​part 29 is provided on the left side of the fixed cover plate 26. A snap-fit ​​block 291 is provided on the inner side of the snap-fit ​​part 29, which can slide left and right. A snap-fit ​​rod 292 is provided on the left side of the snap-fit ​​block 291. A bolt 293 is provided on the top of the snap-fit ​​part 29, and a screw hole is provided on the top of the snap-fit ​​block 291. A snap-fit ​​spring 294 is provided on the right side of the snap-fit ​​block 291, which is located on the inner side of the snap-fit ​​part 29.

[0033] A sealing assembly 2 is provided on the right side of the roller body 1.

[0034] The working principle of the sealed plastic seat roller provided by this utility model is as follows:

[0035] Step 1: When using, first place the extrusion block 21 inside the roller body 1, then sequentially fasten the deformation sealing ring 22, the main sealing ring 23 and the locking ring 24 to one side of the roller body 1. By pushing the fixing cover plate 26 to the right, the fixing hole part inside it is positioned above the sliding column 25. Under the action of the fixing spring 27, each sliding column 25 is pushed out and abuts against the inside of the fixing hole, thereby fixing the fixing cover plate 26.

[0036] Step 2: After the fixed cover plate 26 is fixed, the left end of the adjusting rod 28 is exposed. By rotating the adjusting rod 28, since the circumferential side of the adjusting rod 28 is threaded to the inner side of the fixed cover plate 26, when the adjusting rod 28 is rotated to one side, it will drive the extrusion block 21 to move to the left. The extrusion block 21 will then extrude the deformation sealing ring 22, causing it to deform and expand, thereby improving the sealing effect of the deformation sealing ring 22. Together with the main sealing ring 23, it achieves a high-quality seal on the roller body 1, which can effectively prevent moisture from entering and ensure the roller's life.

[0037] Step 3: With the installation of the snap-fit ​​block 291, snap-fit ​​rod 292, bolt 293 and snap-fit ​​spring 294, the roller body 1 can be installed and disassembled conveniently and quickly.

[0038] Compared with related technologies, the sealed plastic seat roller provided by this utility model has the following beneficial effects:

[0039] By rotating the adjusting rod 28, since the circumferential side of the adjusting rod 28 is threaded to the inner side of the fixed cover plate 26, when the adjusting rod 28 is rotated to one side, it will drive the extrusion block 21 to move to the left. The extrusion block 21 then extrudes the deformation sealing ring 22, causing it to deform and expand, thereby improving the sealing effect of the deformation sealing ring 22. Together with the main sealing ring 23, it achieves a high-quality seal on the roller body 1, effectively preventing moisture from entering and ensuring the roller's lifespan.
