Description

Technical Field

[0001] The utility model belongs to the technical field of roller conveying, and in particular relates to a roller conveying device with a buffer structure. Background Art

[0002] Roller conveyors are suitable for conveying various types of boxes, bags, pallets and other piece goods. Bulk materials, small items or irregular items need to be placed on pallets or in turnover boxes for transportation. They can convey materials with very large single weights. Roller conveyors have high reliability and are easy to use and maintain. However, when conveying heavier goods, traditional roller conveyors lack buffer auxiliary devices, so the heavier goods are inertial and can easily cause collisions between loading and unloading personnel when receiving the goods, causing personal injury, thus posing a safety hazard.

[0003] In the prior art, a Chinese patent with a reference number of CN 216511188 U discloses a buffer device based on roller conveyor, comprising a first concave frame, an inner cavity of the first concave frame being slidably connected to a baffle, a sliding column being fixedly connected between the left and right sides of the inner cavity of the first concave frame and located on the back of the baffle, and a sliding cylinder being slidably connected to the left and right sides of the outer surface of the sliding column. The utility model has the advantage of a buffer function, and solves the problem that the original roller conveyor has no buffer function when in use, thereby preventing the heavy goods from being easily hit by the loading and unloading personnel when receiving the goods under the action of inertia, causing personal injury.

[0004] The comparative document provides a buffer device based on roller conveyor, but the buffer device in the above-mentioned patented roller conveyor device uses hard impact resistance for buffering, so that there will be a certain impact force when the goods come into contact with the buffer device. One end of the roller conveyor device will shake, tilt forward, and vibrate under the impact, affecting the conveying stability of the device and causing certain damage to the device.

[0005] Therefore, a roller conveyor device with a buffer structure is proposed. Utility Model Content

[0006] The utility model provides a roller conveyor device with a buffer structure, aiming to solve the above problems.

[0007] The utility model is implemented as follows: a roller conveyor device with a buffer structure comprises: a fixed frame; a conveying roller rotating on the inner side wall of the fixed frame; a connecting shaft integrally formed at the central position of the outer side wall of the conveying roller; a turntable fixed to one end of the connecting shaft by screws; a fixed cover fixed to the outer side wall of the fixed frame near the outer side of the turntable by bolts; a screw rod screwed on the outer side wall of the fixed cover by threads; a brake pad rotating on one end of the screw rod; and a hand wheel welded to the other end of the screw rod; a guide rod fixed to the outer side wall of the brake pad by screws; a fixed platform fixed to the top of the fixed frame by bolts; a damper fixed to the outer side wall of the fixed platform by bolts; a support frame fixed to the moving end of the damper; and a side guide roller rotating on the inner side wall of the support frame.

[0008] Preferably, the connecting shaft passes through an outer wall of one side of the fixing frame, and the rotating disk is located outside the fixing frame.

[0009] Preferably, the guide rod passes through the fixing cover.

[0010] Preferably, there are six fixing platforms in total, and the six fixing platforms are arranged in groups of three at equal intervals on the top of the fixing frame.

[0011] Preferably, the cross-sections of the fixing frame, the fixing cover and the supporting frame are all U-shaped structures.

[0012] Preferably, there is friction contact between the brake pad and the rotating disk.

[0013] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0014] By controlling the squeezing force between the brake pad and the turntable, the conveyor roller is blocked from rotating, so that the friction between the goods and the conveyor roller is converted from rotational friction to sliding friction. By setting the rotation damping of multiple conveyor rollers to increase gradually, the goods can be gradually stopped during the conveying process without any collision, thus avoiding the problem of shaking, tilting forward and vibration of one end of the roller conveyor device under impact, thereby ensuring the stability of the device's transportation.

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0023] The utility model provides a roller conveyor device with a buffer structure, such as Figure 1-5As shown, it includes a fixing frame 1, a conveying roller 2 is rotatably connected to the inner wall of one side of the fixing frame 1, a connecting shaft 3 is integrally formed at the central position of the outer wall of one side of the conveying roller 2, one end of the connecting shaft 3 is fixedly connected to a turntable 4 by a screw, the connecting shaft 3 passes through the outer wall of one side of the fixing frame 1, the turntable 4 is located on the outer side of the fixing frame 1, a fixing cover 5 is fixedly connected to the outer position of the turntable 4 on the outer wall of one side of the fixing frame 1 by bolts, a screw rod 6 is screwed on the outer wall of the fixing cover 5 away from the fixing frame 1, one end of the screw rod 6 is rotatably connected to a brake pad 7 near the inner position of the fixing cover 5, and the screw rod 6 is screwed on the outer wall of the fixing cover 5 away from the fixing frame 1. A handwheel 8 is welded to the other end, a guide rod 9 is fixedly connected to the outer wall of one side of the brake pad 7 at a position close to the screw rod 6 by screws, a fixed platform 10 is fixedly connected to the top of the fixed frame 1 by bolts, and a total of six fixed platforms 10 are provided, and the six fixed platforms 10 are arranged at equal intervals in a group of three at the top of the fixed frame 1, a damper 11 is fixedly connected to the outer wall of one side of the fixed platform 10 by bolts, and the movable end of the damper 11 is fixedly connected to the support frame 12 by bolts, the cross-sections of the fixed frame 1, the fixed cover 5 and the support frame 12 are all U-shaped structures, and the side guide roller 13 is rotatably connected to the inner wall of the support frame 12.

[0024] It should be noted that, since the existing roller conveyor buffer device uses hard resistance to impact force for buffering, there will be a certain impact force when the goods come into contact with the buffer device. One end of the roller conveyor device will shake, tilt forward, and vibrate under the impact, affecting the conveying stability of the device and causing certain damage to the device. This embodiment controls the extrusion force between the brake pad 7 and the turntable 4 to prevent the conveyor roller 2 from rotating, so that the friction force between the goods and the conveyor roller 2 is converted from rotational friction to sliding friction. By setting the rotation damping of multiple conveyor rollers 2 to gradually increase, the goods can be gradually stopped during the transportation process without collision, thereby avoiding shaking, tilting, and vibrating of one end of the roller conveyor device under impact, thereby ensuring the stability of the device's transportation.

[0025] Specifically, in this embodiment, the scheme mainly includes a turntable 4, a brake pad 7 and a side guide roller 13. When in use, the conveying roller 2 is rotated on the inner side wall of the fixed frame 1 so that the conveying roller 2 conveys the goods. In order to prevent the goods from continuing to move under the action of inertia and causing collision, the rotation resistance of the conveying roller 2 at the required position is adjusted, and the hand wheel 8 is rotated. The hand wheel 8 drives the screw 6 to rotate. Under the guide limit of the guide rod 9, one end of the screw 6 pushes the brake pad 7 to move, and the brake pad 7 contacts the turntable 4. The conveying roller 2 is blocked from rotating by controlling the extrusion force between the brake pad 7 and the turntable 4. When the goods move above the conveying roller 2 whose rotation is blocked, there is horizontal friction between the goods and the conveying roller 2. The rotation damping of the conveying roller 2 is set to be gradually increased, so that the goods can be gradually stopped during the conveying process without collision. When the conveying trajectory of the goods is offset due to factors such as the offset of its own center of gravity, the goods contact the side guide roller 13. The impact force of the goods hitting the side guide roller 13 is reduced by the rotation of the side guide roller 13 and the buffering of the damper 11, so as to avoid the goods from being damaged by collision.

[0026] In a further preferred embodiment of the present invention, Figure 4-5 As shown, the guide rod 9 passes through the fixing cover 5 .

[0027] In this embodiment, the brake pad 7 can be moved horizontally by the guide limit of the guide rod 9, so that the brake pad 7 generates friction resistance after contacting the rotating disk 4.

[0028] In a further preferred embodiment of the present invention, Figure 4 As shown, there is friction contact between the brake pad 7 and the rotating disk 4.

[0029] In this embodiment, the conveying roller 2 is prevented from rotating by utilizing frictional resistance.
