Description

Technical Field

[0001] This utility model relates to the field of logistics conveying equipment technology, specifically a roller conveyor drive device with buffer function. Background Technology

[0002] A roller conveyor is a common type of continuous conveying equipment. Its core structure consists of a series of parallel, freely rotating cylindrical rollers. These rollers are mounted on a fixed frame, forming a conveying path.

[0003] Existing roller conveyors use an eccentric wheel drive structure, which has the following drawbacks: each roller needs to be individually machined with an eccentric structure, resulting in high costs; the drive radius is limited by the roller radius; the drive belt only contacts once per revolution, making it prone to slippage; the contact time is short; the driving force is insufficient; and it is incompatible with standard commercial rollers.

[0004] Based on this, the present invention proposes a roller conveyor drive device with buffer function. Utility Model Content

[0005] To address the aforementioned technical issues, this utility model proposes a roller conveyor drive device with a buffer function. This device can automatically stop when an object gets stuck, eliminating thrust accumulation and protecting goods and equipment. It can be directly adapted to standard rollers, eliminating the processing cost of eccentric wheels and reducing modification difficulty. Through a polygonal design, it achieves multi-point contact, extending the driving time. It is particularly suitable for low-speed, heavy-load scenarios. It can be restarted by manual pushing or by triggering a thicker layer of the transmission belt, offering high operational flexibility. Moreover, it only requires a drive component, transmission belt, and support wheel, without complex sensors or circuits, resulting in low maintenance costs.

[0006] The technical solution to achieve the purpose of this utility model is: a roller conveyor drive device with buffer function, including a transport roller, wherein the transport roller includes roller one, roller two, roller three and roller four, and a housing is provided on the transport roller, and further includes;

[0007] The frame has a conveyor roller rotatably connected to it. The conveyor roller is equipped with a drive component, which includes drive element one, drive element two, drive element three, and drive element four. Drive element one is provided on roller one, drive element two is provided on roller two, drive element three is provided on roller three, and drive element four is provided on roller four. The frame is equipped with a transmission belt, which is adapted to the drive component.

[0008] Preferably, the transmission belt is provided with multiple support pulleys.

[0009] Preferably, the transport roller has a small radius, and the drive component has a large radius.

[0010] Preferably, the driving component is provided with peripheral components, which include peripheral component one, peripheral component two, and peripheral component three.

[0011] Preferably, the transmission belt has a thickened layer.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] In this invention, the machine automatically stops when an object gets stuck, eliminating the accumulation of thrust and protecting goods and equipment. It can be directly adapted to standard rollers, saving the processing cost of eccentric wheels and reducing the difficulty of modification. The polygonal design enables multi-point contact and extends the driving time, making it particularly suitable for low-speed heavy-load scenarios. It can be restarted by manual pushing or by triggering a thicker layer of the transmission belt, providing high operational flexibility. It only requires a driving component, transmission belt, and support wheel, without complex sensors or circuits, resulting in low maintenance costs. Attached Figure Description

[0019] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0020] This utility model provides an improved drive device for a roller conveyor with a buffer function. The technical solution of this utility model is as follows:

[0021] like Figure 1 and Figure 2As shown, a roller conveyor drive device with buffer function includes a transport roller 1, which includes roller one 101, roller two 201, roller three 301 and roller four 401. The transport rollers 1 are arranged in a linear array on the frame 2. The transport roller 1 is provided with a housing 9. The device also includes:

[0022] The frame 2 is rotatably connected to the transport roller 1. The transport roller 1 is equipped with a drive component 3. The cross-section of the drive component 3 is an equilateral triangle. The drive component 3 includes drive element 103, drive element 203, drive element 303 and drive element 403. Drive element 103 is provided on roller 101, drive element 203 is provided on roller 201, drive element 303 is provided on roller 301, and drive element 403 is provided on roller 401. The frame 2 is equipped with a transmission belt 4, which is adapted to the drive component 3. It automatically stops when the object is stuck, eliminates the accumulation of thrust, and protects the goods and equipment. It only requires the drive component 3, transmission belt 4 and support wheel 8, without complex sensors or circuits, and has low maintenance costs.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, the transmission belt 4 is provided with multiple support wheels 8, which are staggered with the driving component 3.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, the transport roller 1 has a small radius 6, the drive component 3 has a large radius 7, and the transmission belt 4 runs below the drive component 3. Its distance from the conveying rotation shaft is greater than the small radius 6 but less than the large radius 7.

[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the driving component 3 is provided with peripheral components 60, which include peripheral component 30, peripheral component 40 and peripheral component 50. Since the peripheral components 60 of the driving component 3 are located at a large radius 7, their movement speed is faster, realizing continuous and rapid driving.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, the transmission belt 4 is provided with a thickened layer 10. When the thickened layer 10 runs to the bottom of the stopped drive member 3, it is lifted up and forced to rotate to the large radius 7 area to re-contact the transmission belt 4.

[0027] The specific working method is as follows: When the transmission belt 4 is running continuously, the polygonal drive component 3, assembled at the end of the standard transport roller 1, contacts the transmission belt 4 with its large radius 7 area. Through friction, it drives the transport roller 1 to rotate, ensuring smooth transport of goods. At this time, the polygonal structure provides multiple contacts per revolution, significantly extending the driving time and avoiding the slippage problem of traditional eccentric wheel drives. If the transport of goods is obstructed (such as the box 9 getting stuck), the transport roller 1 stops rotating. Under the action of resistance, the drive component 3 automatically rotates to the smallest radius 6 area, disengaging from the transmission belt 4. The friction disappears, causing the transport roller 1 to stop completely, thereby eliminating the pushing pressure on the goods and achieving zero-compression protection. After stopping, the drive component 3 remains at the small radius 6 position, and the transmission belt 4 idles. The restart phase offers two options: First, the goods are manually pushed gently to allow the transport roller 1 to re-engage the drive component 3 in its large radius 7 zone with the transmission belt 4, resuming operation. Second, the design relies on a thickened layer 10 at a specific location on the transmission belt 4—when the thickened layer 10 reaches below the stopped drive component 3, it is lifted and forced to rotate to re-engage with the transmission belt 4 in its large radius 7 zone. If the goods are still obstructed at this point, the drive component 3 will disengage again and enter a buffer cycle. If the goods are movable, normal transport resumes. The entire process adaptively switches between drive and disengagement states through a purely mechanical structure, requiring no sensor or circuit intervention. This achieves intelligent buffer shutdown while remaining compatible with standard transport roller 1 and significantly improving drive efficiency in low-speed, heavy-load scenarios.

[0028] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
