Through advanced technology and design, it can achieve precise control of the transportation and temporary storage of items. During operation, it is efficient and stable and can adapt to different work scenarios and types of items. For example, in a logistics distribution center, the adjustable accumulation roller can reasonably accumulate goods according to the cargo flow and processing speed. In a factory production line, it can accurately control the transportation and retention of parts according to the production rhythm. The emergence of the adjustable accumulation roller has greatly improved the flexibility and efficiency of the conveying system, bringing convenience to the production and logistics of various industries.

The floating connection relationship can realize the differential movement or stop of the object relative to the uniformly rotating driving wheel, so that the conveyed object has strong controllability; the pre-pressure of the elastic element can be changed by adjusting the axial position of the clamping member, thereby changing the maximum friction force between the friction plate and the driving wheel, so that the preset friction force can be adjusted according to the weight of the object, thereby enhancing the applicability of the roller of the utility model, and solving the problem that the common roller is a simple cylinder, one end of which is provided with a sprocket or synchronous belt connected to the driving source, the function is relatively simple, and it is difficult to realize the operations of single object forward, backward, stop, etc. often involved in the assembly line.

[0004] In the process of conveying workpieces with the help of an adjustable accumulation roller, there is an existing adjustable accumulation roller such as the above-mentioned one, in which a nut is used as a fastener in the spring part, and cooperates with the thread on the surface of the rotating shaft to limit the position of the spring. Since the accumulation roller will vibrate when in use, when the vibration is transmitted to the nut, the nut is easy to loosen under the action of the vibration and cause its own position to change. When the position of the nut changes, the squeezing effect of the nut on the spring will change synchronously, which will lead to a decrease in the compression of the spring, resulting in a change in the friction coefficient of the roller.

Then the auxiliary component can be disassembled. By setting the auxiliary component, the roller can limit the position of the nut, thereby reducing the problem of the roller nut loosening during use, which causes the friction coefficient of the roller to change, and further improves the stability of the roller in use.

[0026] In this embodiment: the auxiliary component 6 includes a connection unit 61, the connection unit 61 includes a connection column 612, a hexagonal slot 611 is provided on the side surface of the coupling shaft 1, the connection column 612 is plugged into the inner wall of the hexagonal slot 611, the side surface of the connection column 612 is fixedly connected to a limiting sleeve 613, and the limiting sleeve 613 is sleeved with the surface of the limiting nut 5;

[0027] The auxiliary component 6 also includes a restraining unit 62, which includes a rack 621, which is fixedly connected to the inner wall of the hexagonal slot 611, and an installation cavity 622 is opened on the surface of the connecting column 612. The connecting column 612 is located on the inner wall of the installation cavity 622 and is slidably connected to a force-carrying plate 623. The upper surface of the force-carrying plate 623 is fixedly connected to a latch tooth 624, which is plugged into the tooth groove of the rack 621. The lower surface of the force-carrying plate 623 is fixedly connected to a limit spring 625, and the limit spring 625 is fixedly connected to the inner wall of the installation cavity 622. The lower surface of the force-carrying plate 623 is fixedly connected to a linkage rod 626, and the side surface of the linkage rod 626 is fixedly connected to a control pressure plate 627.

[0028] Specifically, the connecting column 612 is hexagonal, and the length of the connecting column 612 is equal to the length of the limiting sleeve 613. By designing the connecting column 612 to be hexagonal, the connecting column 612 can be stably inserted into the hexagonal slot 611, thereby improving the restraining effect on the limiting sleeve 613.

[0029] Specifically, the inner wall of the limiting sleeve 613 is hexagonal, and the limiting sleeve 613 is sleeved with the surface of the connecting shaft 1 .

[0030] In this embodiment, the connection portion between the limiting nut 5 and the connecting shaft 1 can be protected by the limiting sleeve 613 , and the position of the limiting nut 5 can be limited by the action of the connecting column 612 .

[0031] Specifically, there are two racks 621 , which are symmetrically arranged about the connecting shaft 1 . Through the cooperation between the racks 621 and the latch teeth 624 , the position of the connecting column 612 can be restricted with the assistance of the load-bearing plate 623 .

[0032] In this embodiment, there are multiple latching teeth 624 , and the multiple latching teeth 624 are horizontally distributed with respect to the force-carrying plate 623 .

[0033] In this embodiment, the position of the force-carrying plate 623 can be restricted by inserting the latching teeth 624 into the rack 621 , so as to ensure that the force-carrying plate 623 can be restricted at a predetermined position.

[0034] Specifically, there are multiple limit springs 625 , which are horizontally distributed with respect to the force-carrying plate 623 . The limit springs 625 can constrain the position of the force-carrying plate 623 to ensure that the force-carrying plate 623 can stably support the latching teeth 624 .

There are two linkage rods 626 , and the two linkage rods 626 are symmetrically arranged about the control pressure plate 627 .

[0036] In this embodiment: the linkage rod 626 can cooperate with the control pressure plate 627, and under the operation of the staff, the force-carrying plate 623 is pulled downward to squeeze the limit spring 625.

[0037] Working principle: when the accumulation roller is working, the chain installed on the surface of the transmission device 2 drives the transmission device 2. Under the action of the friction structure inside the roller body 3, the transmission device 2 drives the roller body 3 to rotate. During the rotation of the roller body 3, the workpiece can be transported. After the adjustment of the friction coefficient of the accumulation roller is completed, the end face of the connecting column 612 with the clamping tooth 624 is aligned with the rack 621 to push the limiting sleeve 613. The limiting sleeve 613 pushes the connecting column 612. The connecting column 612 is inserted into the hexagonal slot 611. During the movement of the connecting column 612, the clamping tooth 624 is pushed by the force-carrying plate 623. The clamping tooth 624 contacts the rack 621 during movement, and under the guidance of the inclined surface of the rack 621, the clamping tooth 624 is pressed downward by the force-carrying plate 623 to squeeze the limiting spring 625. The limiting spring 625 is squeezed and deformed. When the limiting sleeve 613 is sleeved to the surface of the limiting nut 5, the limiting sleeve 613 is stopped, and at the same time, the force-carrying plate 623 loses the clamping tooth. The thrust applied by the tooth 624 causes the latch tooth 624 to stop moving and lose the pressure applied to the limit spring 625. The limit spring 625 loses the pressure and rebounds, and while rebounding, it cooperates with the load-bearing plate 623 to push the latch tooth 624 into the tooth groove of the rack 621. Then, with the cooperation of the latch tooth 624 and the rack 621, the position of the load-bearing plate 623 and the connecting column 612 can be limited, and the position of the limit sleeve 613 can be constrained. When the staff needs to disassemble the auxiliary component 6, they press the control pressure plates 627 on the upper and lower sides. The control pressure plates 627 cooperate with the linkage rod 626 to pull the load-bearing plate 623, so that the latch tooth 624 is disengaged from the rack 621. Then, the auxiliary component 6 can be disassembled. By setting the auxiliary component 6, the roller can limit the position of the nut, thereby reducing the problem of the roller nut loosening during use, resulting in a change in the friction coefficient of the roller, and further improving the stability of the roller in use.
