Description

Technical Field

[0001] This utility model belongs to the field of cargo storage technology, and in particular relates to a damping adjustment mechanism for rollers of gravity sliding shelves. Background Technology

[0002] Gravity sliding racks, also known as gravity flow racks, are a type of warehouse racking system that uses gravity to store and automatically slide goods. They are widely used in modern logistics and warehousing. Some gravity sliding racks are equipped with damping devices to control the speed at which goods slide down. By adjusting the damping force, collisions and damage caused by excessive speed can be avoided, ensuring that goods arrive at their designated locations safely and smoothly.

[0003] When using gravity sliding racks to dampen and slow down goods, due to the significant weight differences among different goods, excessively heavy goods may slide down too fast due to insufficient damping, which can easily lead to collisions and damage, or even safety accidents. On the other hand, excessively light goods may not slide down smoothly due to excessive damping, affecting the efficiency of warehousing operations. Therefore, it is necessary to provide a roller damping adjustment mechanism for gravity sliding racks, which adopts an adjustable damping deceleration structure to adapt to the deceleration requirements of different goods and ensure that the goods slow down and stop after reaching the designated position. Utility Model Content

It adopts an adjustable damping deceleration structure to adapt to the deceleration requirements of different goods, ensuring that the goods can slow down and stop after reaching the designated position, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a gravity sliding rack roller damping adjustment mechanism includes multiple rotating parts rotatably connected inside the gravity rack, a damping roller rotatably connected between two of the rotating parts at the same height, a support column fixedly connected to the gravity rack below the damping roller, and adjustment components provided on the front and rear sides of the bottom of the support column. The adjustment components include a damper fixedly installed in the inner cavity of the gravity rack, a spring sleeved on the surface of the damper, a baffle slidably connected to the surface of the damper, an external threaded assembly fixedly connected to the right side of the baffle, and an internal threaded assembly rotatably connected to the right side of the damper surface. The external threaded assembly is threadedly connected to the inner cavity of the internal threaded assembly.

[0006] Preferably, the two ends of the spring are in contact with the end of the damper and the inner cavity of the baffle, respectively.

[0007] Preferably, the extended end of the damper is fixedly connected to a sliding pin, and an arc-shaped groove is provided at the bottom of one side of the rotating component, with the sliding pin slidably connected in the inner cavity of the arc-shaped groove.

[0008] Preferably, the top and bottom of the baffle inner cavity are fixedly connected to limit sliders, and the top and bottom of the damper are provided with limit grooves, with the limit sliders slidably connected to the inner cavity of the limit grooves.

[0009] Preferably, multiple support rollers are rotatably connected to both sides of the inner cavity of the support column.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses the setting of the adjustment component to push the rotating part forward, and at the same time, the damping force can be adjusted. With the cooperation of the adjustment component and the rotating part, the damping force of the damping roller can be adjusted, so as to achieve the purpose of easy adjustment of the damping force and adjustment of the corresponding deceleration effect for different cargo weights.

[0021] In the following description, embodiments of the gravity sliding shelf roller damping adjustment mechanism of this utility model will be described with reference to the accompanying drawings.

[0022] Figure 1-4 This invention illustrates a gravity sliding rack roller damping adjustment mechanism according to an embodiment of the present invention. It includes multiple rotating parts 2 rotatably connected inside the gravity rack 1. A damping roller 3 is rotatably connected between two rotating parts 2 at the same height. A support column 5, fixedly connected to the gravity rack 1, is located below the damping roller 3. Multiple support rollers 6 are rotatably connected to both sides of the inner cavity of the support column 5. Adjustment components 4 are located on the front and rear sides of the bottom of the support column 5. The adjustment components 4 include a damper 41 fixedly installed inside the gravity rack 1. A spring 43 is sleeved on the surface of the damper 41. A baffle 44 is slidably connected to the surface of the damper 41. The two ends of the spring 43 contact the end of the damper 41 and the inner cavity of the baffle 44, respectively. A sliding pin 47 is fixedly connected to the protruding end of the damper 41. An arc-shaped groove 42 is formed at the bottom of one side of the rotating part 2. The sliding pin 47 is slidably connected in the inner cavity of the arc-shaped groove 42. With the cooperation of the arc-shaped slide groove 42, the damper 41 can rotate stably during horizontal advancement, thus avoiding damage to the damper 41 due to rotational deviation during rotation. The top and bottom of the inner cavity of the baffle 44 are fixedly connected to the limit slider 7, and the top and bottom of the damper 41 are provided with limit slide grooves 8. The limit slider 7 is slidably connected to the inner cavity of the limit slide groove 8. Through the cooperation of the limit slider 7 and the limit slide groove 8, the baffle 44 is limited and guided, so that the baffle 44 can only slide horizontally. This avoids the phenomenon that the internal threaded kit 46 drives the baffle 44 to rotate through the external threaded kit 45 during rotation. The right side of the baffle 44 is fixedly connected to the external threaded kit 45, and the right side of the surface of the damper 41 is rotatably connected to the internal threaded kit 46. The external threaded kit 45 is threadedly connected to the inner cavity of the internal threaded kit 46.

[0023] Working Principle: When this utility model is in use, goods slide from the upper right side of the inner cavity of the gravity-fed shelf 1 to the lower left. When the goods slide to the top of the support column 5, the surface of the goods comes into contact with the surface of the damping roller 3. Due to the weight of the goods, the damping roller 3 is squeezed and rotates to the left. During the rotation of the damping roller 3, the rotating component 2 is driven to rotate. At the same time, the rotating component 2, through the cooperation of the arc-shaped groove 42 and the sliding pin 47, squeezes the protruding end of the damper 41, causing the damper 41 and the spring 43 to retract, thus reducing the damping force. The damping roller 3 and the rotating part 2 rotate slowly, thereby damping and slowing down the goods. Depending on the different weights of the goods, their inertia varies, so the damping strength of the damping roller 3 needs to be adjusted. During adjustment, the user rotates the internal threaded assembly 46. As the internal threaded assembly 46 rotates at the origin, the inner threaded assembly 46 pushes the baffle 44 left and right through the cooperation of its inner wall thread and the surface thread of the external threaded assembly 45, thereby adjusting the pre-tension state of the spring 43. If it is pre-tightened, the damping strength is greater; if it is pre-loosened, the damping strength is smaller.

[0024] In summary, the gravity sliding shelf roller damping adjustment mechanism, through the setting of the adjustment component 4, propels the rotating part 2 and adjusts the damping force. With the cooperation of the adjustment component 4 and the rotating part 2, the damping force of the damping roller 3 can be adjusted, thus achieving the purpose of easy adjustment of the damping force and adjustment of the corresponding deceleration effect for different cargo weights.
