Technical Field
[0001] This utility model relates to the field of raw material storage and transfer equipment in the aluminum processing industry, specifically a rack for placing scattered aluminum materials. Background Technology
[0002] In the aluminum processing industry, aluminum bars are a core raw material, and their storage and transportation directly affect production efficiency and product quality. Because aluminum bars are mostly cylindrical, they are prone to rolling and shifting when scattered, leading to storage chaos and potential surface scratches and deformation from collisions, affecting subsequent processing accuracy. Currently, common equipment for storing scattered aluminum bars includes ordinary shelves, simple supports, and traditional recessed storage platforms, but all have significant drawbacks.
[0003] Ordinary shelving lacks a targeted positioning structure, allowing aluminum bars to easily roll along the shelf surface after placement, resulting in messy stacking. Retrieval and transfer require repeated manual rearrangement, making the operation cumbersome and inefficient. Simple supports often use rigid support designs without cushioning mechanisms, making it easy for aluminum bars to collide hard with the supports, causing surface wear. The lack of anti-slip measures further exacerbates the risk of aluminum bar displacement. Traditional recessed placement platforms can initially limit the rolling of aluminum bars through the recesses, but the fixed recess size makes them unsuitable for placing aluminum bars of different diameters. Furthermore, the lack of an automatic clamping structure means that lateral displacement of the aluminum bars remains a risk. Subsequent transfer using a crane requires manual adjustment of the aluminum bar's position to ensure precise alignment with the crane's grippers, extending operation time and increasing labor intensity.
[0004] Furthermore, some high-end placement equipment uses motor-driven clamping mechanisms to fix aluminum rods, but this suffers from problems such as complex structure, high manufacturing cost, high energy consumption, and difficult maintenance, making it unsuitable for the batch handling of scattered aluminum rods in small and medium-sized enterprises. At the same time, existing equipment generally neglects buffering and shock absorption design during the aluminum rod placement process; the impact of the aluminum rods' gravity easily leads to wear and tear on the equipment itself, shortening its service life and further aggravating surface damage to the aluminum rods. Therefore, developing a scattered aluminum rod placement rack that is simple in structure, easy to operate, highly adaptable, and capable of achieving stable positioning, effective protection, and convenient subsequent transportation of aluminum rods has become an urgent need to address the current industry pain points. Utility Model Content
[0005] The purpose of this utility model is to provide a material outlet connection structure for a coal mill hopper. After the aluminum rods are placed in the arc-shaped placement groove and arc-shaped seat, the gravity drives the guide column to move down along the sliding hole. The guide plate along the guide groove ensures the smooth displacement of the arc-shaped seat. The first and second springs are compressed synchronously to achieve buffering and shock absorption. At the same time, the downward movement of the arc-shaped seat is linked to the rotating shaft, connecting parts and auxiliary shaft to drive the gripper to flip and clamp the aluminum rods through the adapted arc surface to prevent rolling. The anti-slip buffer sponge layer improves the positioning stability and facilitates the precise docking and transfer of the crane gripper in the future.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A scattered aluminum material placement rack includes a placement platform, characterized in that: upward-facing frame bodies are provided on the left and right sides of the top surface of the placement platform; symmetrical arc-shaped placement grooves are provided on the top of the frame bodies on both sides; a guide groove is provided at the center of the bottom of the placement groove; a vertically penetrating sliding hole is provided in the center of the placement platform; a guide post is slidably installed in the sliding hole; an arc-shaped seat is provided on the top of the guide post; the arc-shaped seat is aligned with the central axis of the arc surface of the two arc-shaped placement grooves; guide plates extend from the arc-shaped seat to both sides along the central axis of its arc surface; the guide plates are inserted into the guide grooves at the bottom of the placement grooves; a first spring is sleeved on the guide post; the bottom of the first spring is fixed to the placement platform, and the top is fixed to the bottom of the arc-shaped seat.
[0007] A placement seat is fixedly installed at the bottom of the placement platform. A second spring is fixedly installed at the bottom of the placement seat corresponding to the sliding hole of the placement platform. The other end of the second spring passes through the sliding hole and is fixedly connected to the bottom surface of the guide column.
[0008] The placement base and the placement platform are fixedly connected by axially arranged support feet, which are evenly distributed around the circumference of the placement base to ensure the coaxiality of the placement platform and the placement base.
[0009] Rotating bases are provided on the front and rear sides of the top of the placement platform. The bottom end of the auxiliary shaft is rotatably mounted on the rotating base. A clamp is fixedly provided on the top of the auxiliary shaft. The clamp is placed above the arc-shaped seat. An avoidance groove is opened on the side of the arc-shaped seat near the auxiliary shaft. The rotating shaft is horizontally fixed in the avoidance groove. A connecting piece is slidably sleeved on the auxiliary shaft. The connecting piece also includes a sleeve perpendicular to the sliding direction. The sleeve is rotatably connected to the rotating shaft.
[0010] The gripper includes upper and lower arc surfaces, with the curvature of the upper arc surface being greater than that of the lower arc surface, and the curvature of the lower arc surface matching the curvature of the arc-shaped base. The lower arc surface of the gripper is in contact with the surface of the aluminum material to achieve clamping and fixation.
[0011] The top surface of the arc-shaped seat and the arc-shaped placement groove is provided with a cushioning sponge layer, and the surface of the sponge layer is treated with anti-slip treatment.
[0012] When scattered aluminum bars are placed, their surfaces precisely align with the arc-shaped placement slots and top surfaces of the arc-shaped seats on both sides of the frame. The arc-shaped structure matches the cylindrical characteristics of the aluminum bars, achieving initial anti-rolling positioning. The cushioning sponge layer not only prevents wear on the aluminum bars but also further restricts their displacement through anti-slip treatment. The weight of the aluminum bars causes the guide post to move downwards along the sliding hole, and the guide plate slides synchronously along the guide groove, ensuring stable displacement of the arc-shaped seat. The first and second springs compress synchronously, absorbing the impact force through elastic deformation, allowing the aluminum bars to land smoothly. During this process, the downward movement of the arc-shaped seat drives the rotating shaft to slide along the auxiliary shaft, causing the auxiliary shaft to rotate around the rotating base. The gripper then presses down and, through its lower adaptable arc surface, tightly adheres to the surface of the aluminum bars, forming a firm grip and completely preventing the aluminum bars from rolling. When subsequent transfer using a crane is required, the crane gripper can directly and precisely engage with the fixed aluminum bars without additional adjustment of their position, significantly improving transfer efficiency and ease of operation.
[0013] Compared with the prior art, the beneficial effects of this utility model are: Firstly, the combination of an arc-shaped placement slot and an arc-shaped base with a gravity-linked automatic gripping design solves the problem of easy rolling and displacement of aluminum bars in traditional placement racks, achieving stable positioning of the aluminum bars after placement. Secondly, the synergistic effect of the double spring buffer structure and the anti-slip buffer sponge layer avoids collision damage during placement of the aluminum bars and prevents surface wear, improving the protection effect of the aluminum material. Thirdly, after the aluminum bars are precisely clamped and fixed, they can be directly and precisely connected to the crane gripper without manual adjustment, greatly simplifying the transfer operation process and improving subsequent transportation efficiency. Fourthly, the overall structure relies on the weight of the aluminum bars themselves to achieve automatic positioning, buffering, and clamping, without the need for additional power drive, making it easy to operate and low in cost, suitable for the batch placement and transportation needs of scattered aluminum bars.

[0015] The technical solutions of the present invention will now be described in detail with reference to the accompanying drawings of the embodiments.
[0016] like Figure 1-3 As shown, a scattered aluminum material placement rack includes a placement platform 1. The platform 1 has upward-facing frame bodies 11 on its top left and right sides. Symmetrically arranged arc-shaped placement grooves 12 are formed on the top of the frame bodies 11 on both sides. A guide groove 13 is formed downward at the center of the bottom of each placement groove 12. A vertically penetrating sliding hole 14 is formed at the center of the placement platform 1. A guide post 2 is slidably installed in the sliding hole 14. An arc-shaped seat 21 is provided at the top of the guide post 2. The arc-shaped seat 21 is aligned with the central axis of the arc surface of the arc-shaped placement grooves 12 on both sides. Guide plates 22 extend from the arc-shaped seat 21 to both sides along its central axis. The guide plates 22 are inserted into the guide grooves 13 at the bottom of the placement grooves 12. A first spring 23 is sleeved on the guide post 2. The bottom of the first spring 23 is fixed to the placement platform 1, and the top is fixed to the bottom of the arc-shaped seat 21.
[0017] The bottom of the placement platform 1 is fixedly provided with a placement seat 3. The center of the placement seat 3 is fixedly provided with a second spring 31 corresponding to the bottom of the sliding hole 14 of the placement platform 1. The other end of the second spring 31 passes through the sliding hole 14 and is fixedly connected to the bottom surface of the guide post 2.
[0018] The placement seat 3 and the placement platform 1 are fixedly connected by axially arranged support feet. The support feet are evenly distributed around the circumference of the placement seat 3 to ensure the coaxiality of the placement platform 1 and the placement seat 3.
[0019] Rotating bases 41 are provided on the front and rear sides of the top of the placement platform 1. The bottom end of the auxiliary shaft 42 is rotatably mounted on the rotating base 41. A clamp 43 is fixedly provided on the top end of the auxiliary shaft 42. The clamp 43 is placed above the arc-shaped seat 21. An avoidance groove 44 is opened on the side of the arc-shaped seat 21 near the auxiliary shaft 42. A rotating shaft 45 is horizontally fixed in the avoidance groove 44. A connecting piece 46 is slidably sleeved on the auxiliary shaft 42. The connecting piece 46 also includes a sleeve perpendicular to the sliding direction, which is rotatably connected to the rotating shaft 45.
[0020] The gripper 43 includes upper and lower arc surfaces. The curvature of the upper arc surface is greater than that of the lower arc surface, and the curvature of the lower arc surface is adapted to the curvature of the arc-shaped seat 21. The lower arc surface of the gripper 43 is in contact with the surface of the aluminum material to achieve clamping and fixing.
[0021] The top surfaces of the arc-shaped seat 21 and the arc-shaped placement groove 12 are provided with a buffer sponge layer, and the surface of the sponge layer is treated with anti-slip treatment.
[0022] In practical applications, this utility model of a scattered aluminum rod placement rack first ensures the overall stability of the device. The placement base 3 is fixedly connected to the placement platform 1 through circumferentially evenly distributed support feet, ensuring coaxiality between the two and providing a stable foundation for the coordinated operation of subsequent components. In the initial state, both the first spring 23 and the second spring 31 are in a naturally extended state. The top surface of the arc-shaped base 21 is higher than the top surface of the arc-shaped placement grooves 12 on both sides of the frame 11. The clamp 43 is in an upward-opening state under the pull of the connecting piece 46 and the rotating shaft 45. The clearance groove 44 provides sufficient space for the movement of the connecting piece 46.
[0023] When it is necessary to place scattered aluminum rods, place the aluminum rods horizontally on the top surface of the arc-shaped seat 21. The cylindrical surface of the aluminum rods fits precisely with the arc-shaped structure, initially restricting their radial rolling. At the same time, the anti-slip buffer sponge layer on the top surface of the arc-shaped seat 21 and the placement groove 12 directly contacts the surface of the aluminum rods, which not only avoids the aluminum rods from colliding with hard parts and causing wear, but also further improves the initial positioning stability through anti-slip treatment.
[0024] The weight of the aluminum rod acts on the arc-shaped seat 21, causing the arc-shaped seat 21 to drive the guide post 2 to slide downwards along the sliding hole 14 in the center of the placement platform 1. At this time, the guide plates 22 on both sides of the arc-shaped seat 21 move downwards synchronously along the guide groove 13 at the bottom of the placement groove 12, effectively preventing the arc-shaped seat 21 from tilting during movement and ensuring its stable displacement along the axis. During this process, the first spring 23 on the guide post 2 is compressed by the arc-shaped seat 21, and the second spring 31 corresponding to the bottom of the sliding hole 14 in the placement seat 3 is simultaneously squeezed by the guide post 2. The double spring structure absorbs the impact force when the aluminum rod is placed through elastic deformation, achieving buffering and shock absorption, and ensuring that the aluminum rod is placed smoothly.
[0025] As the arc-shaped seat 21 continues to move downward, the rotating shaft 45 in its side clearance groove 44 moves downward synchronously, causing the connecting piece 46 fitted on the auxiliary shaft 42 to slide vertically along the auxiliary shaft 42. This, in turn, drives the auxiliary shaft 42 to rotate inward around the rotating base 41 on both sides of the top of the placement platform 1, and the gripper 43 at the top of the auxiliary shaft 42 presses down accordingly. Since the lower arc surface of the gripper 43 matches the arc surface curvature of the arc-shaped seat 21, when it moves down to the position of the arc-shaped placement grooves 12 on both sides, the lower arc surface of the gripper 43 is tightly attached to the surface of the aluminum rod, forming a firm grip on the aluminum rod and completely preventing the aluminum rod from rolling and shifting.
[0026] When aluminum bars need to be transferred using a crane, the crane's gripper can directly and precisely engage with the clamped aluminum bar, eliminating the need for manual adjustment of the bar's position and significantly simplifying the operation. After the crane gripper clamps the aluminum bar, it is lifted upwards, releasing the pressure of the aluminum bar on the arc-shaped seat 21. The first spring 23 and the second spring 31 extend under the elastic restoring force, pushing the guide post 2 and the arc-shaped seat 21 to return to their original position. The rotating shaft 45 drives the connecting piece 46 to move upwards along the auxiliary shaft 42. The auxiliary shaft 42 rotates outwards around the rotating base 41, causing the gripper 43 to open and release the aluminum bar, completing a single placement and transfer operation and meeting the batch processing needs of scattered aluminum bars.
