[0001] This utility model relates to the technical field of aluminum material conveying equipment, and in particular to an aluminum material conveying device. Background Technology

[0002] Aluminum is a metallic material composed of aluminum and other alloying elements. It has a series of excellent properties, such as low density, high strength, good corrosion resistance, and good electrical and thermal conductivity. Therefore, it is widely used in many fields.

[0003] In the processing and production of aluminum materials, it is necessary to transport the aluminum materials to facilitate subsequent processing steps such as cutting, welding, and surface treatment. However, existing aluminum material conveying devices often cannot effectively limit and fix aluminum materials of different sizes and shapes during the transport process. This can lead to situations where the aluminum materials are prone to deviation, shaking, or even falling during transport, thereby affecting the subsequent processing quality and production efficiency.

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] Please see Figures 1-4 An aluminum material conveying device includes a mounting base 100, a first limiting mechanism 200, a second limiting mechanism 300, and a third limiting mechanism 400. The mounting base 100 has a receiving end face 110 for placing aluminum material. The first limiting mechanism 200 is connected to the mounting base 100 and includes a first limiting member movably connected to the mounting base 100. The first limiting member can move along a first direction and abuts against the aluminum material. The second limiting mechanism 300 is connected to the mounting base 100 and includes a second limiting member movably moved along a second direction and abuts against the aluminum material. The third limiting mechanism 400 includes a third limiting member movably connected to the second limiting mechanism 300 and can move along a third direction and abuts against the aluminum material. The first direction, the second direction, and the third direction intersect.

[0030] In this embodiment, as Figure 1 As shown, the mounting base 100 is a rectangular block structure. The mounting base 100 is placed horizontally, and its upper surface forms a receiving end face 110 to receive the aluminum material. During transportation, the aluminum material is placed on the receiving end face 110, with the length direction of the aluminum material aligned with the length direction of the mounting base 100. The first direction is the length direction of the mounting base 100, the second direction is the vertical direction, and the third direction is the width direction of the mounting base 100. A first limiting mechanism 200 is connected to the mounting base 100, and its first limiting member can move along the length direction of the mounting base 100 to engage with both end faces of the aluminum material. The mounting base 100 is equipped with a second limiting mechanism 300, which can move vertically relative to the receiving end face 110 to abut against the upper end face of the aluminum material, thereby limiting the movement of the aluminum material in the vertical direction. In addition, a third limiting member is movably connected to the second limiting mechanism 300, which can move along the width direction of the mounting base 100 to abut against the two sides of the aluminum material, thereby limiting the movement of the aluminum material in the width direction.

[0031] In practical work, the aluminum material is first placed on the receiving end face 110 of the mounting base 100, then the first limiting member is moved so that the first limiting member abuts against the end face of the aluminum material, then the second limiting member is moved so that the second limiting member abuts against the upper end face of the aluminum material, and finally the third limiting member is moved so that the third limiting member abuts against the side of the aluminum material, thereby limiting and fixing the aluminum material in three directions to ensure the stability of transportation.

[0032] In the above structure, by setting mutually intersecting first, second, and third direction limiting mechanisms, the aluminum material can be limited and fixed from multiple directions, effectively avoiding problems such as reduced subsequent processing quality and production interruption caused by the aluminum material shifting, shaking, or falling during transportation. This improves the fixing effect and stability of the aluminum material during transportation. At the same time, the first, second, and third limiting components can move in their respective directions, which can also meet the fixing requirements for transporting aluminum materials of different sizes and shapes, improving the applicability of the device and thus increasing production efficiency.

[0033] In the specific structure of the second limiting mechanism 300, the second limiting mechanism 300 includes a crossbeam 310, with mounting brackets 320 at both opposite ends of the crossbeam 310. The mounting brackets 320 are connected to the mounting base 100. The crossbeam 310 is arranged opposite to the receiving end face 110 along the second direction. The second limiting member includes a second pressure plate body 330, which is movably connected to the crossbeam 310 and can move along the second direction to abut against the aluminum material. The second limiting mechanism 300 includes a drive cylinder 340, with the fixed end of the drive cylinder 340 fixedly connected to the crossbeam 310 and the movable end of the drive cylinder 340 fixedly connected to the second pressure plate body 330.

[0034] In this embodiment, as Figure 2As shown, the crossbeam 310 is a rectangular plate structure, arranged horizontally and vertically above the mounting base 100. The length of the crossbeam 310 is consistent with the width of the mounting base 100. At both ends of the crossbeam 310 along its length, there are mounting brackets 320 extending vertically downwards. The bottom end of the mounting brackets 320 is connected to the mounting base 100. A second pressure plate 330 is movably connected to the crossbeam 310. The second pressure plate 330 is a rectangular plate structure and is placed horizontally on the crossbeam 310. Between 10 and the receiving end face 110, the length direction of the second pressure plate body 330 is consistent with the length direction of the crossbeam 310. The second pressure plate body 330 can move relative to the crossbeam 310 in the vertical direction, so that the second pressure plate body 330 moves to abut against the upper end face of the aluminum material. The fixed end of the drive cylinder 340 is fixed to the upper side of the crossbeam 310, and the movable end of the drive cylinder 340 passes through the crossbeam 310 and is fixedly connected to the upper end of the second pressure plate body 330. The extension and retraction movement of the drive cylinder 340 drives the second pressure plate body 330 to move in the vertical direction.

[0035] The structure is simple. By driving the second pressure plate 330 to move through the hydraulic cylinder 340, the accuracy of movement is improved. The second pressure plate 330 can be accurately moved to the position of contact with the aluminum material and apply appropriate pressure for limiting. The hydraulic cylinder 340 can provide more stable and precise power output, ensuring that the aluminum material will not shake, deviate or even fall due to displacement in the second direction during the conveying process. This greatly improves the stability of aluminum material conveying, thereby improving the quality and efficiency of the entire processing process.

[0036] Specifically, the second limiting mechanism 300 includes an elastic buffer plate 350 and a spring 360, and the end face of the second pressure plate 330 near the aluminum material is connected to the elastic buffer plate 350 through the spring 360.

[0037] In this embodiment, as Figure 2 , Figure 3As shown, the lower end face of the second pressure plate 330 is connected to an elastic buffer plate 350, wherein the elastic buffer plate 350 is a rectangular plate structure with elastic deformation. The upper end face of the elastic buffer plate 350 is connected to the upper end face of the second pressure plate 330 through a spring 360. Specifically, before the second pressure plate 330 comes into contact with the aluminum material, the spring 360 is in a naturally extended state, and a certain distance is maintained between the elastic buffer plate 350 and the second pressure plate 330. This distance is determined by the natural length of the spring 360. When the second pressure plate 330 moves toward the aluminum material and comes into contact with it under the push of the drive cylinder 340, the elastic buffer plate 350 comes into contact with the surface of the aluminum material. Due to its own elasticity, the elastic buffer plate 350 can deform to adapt to the surface shape of the aluminum material and fit tightly against it. At the same time, the spring 360 begins to be compressed. As the second pressure plate 330 continues to apply pressure to the aluminum material, the spring 360 is further compressed. The reverse elastic force generated during the compression of the spring 360 acts on the elastic buffer plate 350, so that the elastic buffer plate 350 always fits tightly against the surface of the aluminum material and limits the movement of the aluminum material. The combination of the elastic buffer plate 350 and the spring 360 effectively avoids rigid contact between the second pressure plate 330 and the aluminum surface. The buffering effect of the elastic buffer plate 350 and the spring 360 can effectively absorb the impact force generated during the limiting process. At the same time, due to the elastic characteristics of the elastic buffer plate 350 and the spring 360, this structure can adapt to aluminum materials of different thicknesses, shapes and surface conditions, further improving its applicability.

[0038] In addition, the mounting bracket 320 is provided with a first slide groove 321 extending in the first direction, and the mounting base 100 is provided with a first guide rail 120 extending in the first direction on both opposite sides. The first slide groove 321 and the first guide rail 120 are connected in cooperation, and the crossbeam 310 can move in the first direction.

[0039] In this embodiment, as Figure 1 As shown, the mounting base 100 has first guide rails 120 on both sides along the width direction. The first guide rails 120 extend along the length direction of the mounting base 100. Correspondingly, the mounting bracket 320 has a first sliding groove 321 at the bottom. The first sliding groove 321 is connected to the first guide rail 120, so that the crossbeam 310 can move along the length direction of the mounting base 100. This can adapt to the needs of transporting aluminum materials of different lengths and placement positions. For longer aluminum materials, the crossbeam 310 can be moved to a suitable position, which greatly improves the versatility of the equipment.

[0040] Specifically, multiple crossbeams 310 are provided, and these multiple crossbeams 310 are connected to the mounting base 100 along the first direction. Providing multiple crossbeams 310 along the length of the mounting base 100 effectively increases the number of limiting points for longer aluminum materials, further improving the stability of the limiting action.

[0041] In the specific structure of the third limiting member, the third limiting member includes two third pressure plate bodies 410. One end of the third pressure plate body 410 is movably connected to the crossbeam 310. The two third pressure plate bodies 410 are arranged relatively spaced along a third direction. The third pressure plate body 410 can abut against the aluminum material when it moves along the third direction of the crossbeam 310. A first elastic pad 420 is provided at the end of the third pressure plate body 410 near the aluminum material. The third limiting mechanism 400 includes a first drive screw 430. The crossbeam 310 is provided with a first moving groove 311. The first drive screw 430 is movably connected to the first moving groove 311. A first slider 440 is fixedly connected to one end of the third pressure plate body 410 and is engaged with the first drive screw 430. The first slider 440 is inserted into the first moving groove 311. The first drive screw 430 can rotate around its own axis to drive the first slider 440 to move along the third direction of the first moving groove 311.

[0042] In this embodiment, as Figure 2 , Figure 3 As shown, the third pressure plate 410 is a rectangular plate structure. Two third pressure plates 410 are arranged at intervals relative to each other along the width direction of the mounting base 100. The upper end of the third pressure plate 410 is movably connected to the crossbeam 310. In use, the two third pressure plates 410 can be moved along the width direction of the mounting base 100 and abut against and clamp the aluminum material, thereby limiting the aluminum material in the width direction. This structure is simple and can be moved according to the shape and size of the transported aluminum material, further improving its applicability. Specifically, a first moving groove 311 is provided at opposite ends of the lower end face of the crossbeam 310. The first moving groove 311 opens downward and extends along the length of the crossbeam 310. The first drive screw 430 is movably connected in the first moving groove 311 by means of bearings or the like, so that it can rotate around its own axis. One end of the first drive screw 430 extends out of the crossbeam 310 and is equipped with an operating handle or a drive device such as a motor, so that it can be driven manually by the operator or by a power device. The first slider 440 is fixedly connected to the upper end of the third pressure plate body 410. Its shape matches the first moving groove 311. The first slider 440 is provided with a threaded hole that matches the first drive screw 430 and is connected to the first drive screw 430 for transmission. When the first drive screw 430 rotates, the first slider 440 moves along the width of the mounting base 100 along the first moving groove 311, thereby driving the third pressure plate body 410 to move. In addition, a first elastic pad 420 is provided at the end of the third pressure plate 410 near the aluminum material. The first elastic pad 420 can be made of elastic material such as rubber or silicone, which can buffer the pressure of the third pressure plate 410 on the aluminum material and avoid scratches, indentations and other damage to the surface of the aluminum material caused by rigid contact.

[0043] The threaded transmission between the first drive screw 430 and the first slider 440 improves the precise control of the movement position of the third pressure plate 410, and the structure is simple and easy to operate.

[0044] Furthermore, the third pressure plate 410 is a telescopic structure. In this embodiment, the third pressure plate 410 can be a structure that telescopically extends in the vertical direction. The third pressure plate 410 may include a plate body and a telescopic rod, wherein one end of the telescopic rod is connected to the first slider 440 and the other end is connected to the plate body. The telescopic rod extends in the vertical direction, and the telescopic movement of the telescopic rod drives the plate body to move in the vertical direction, thereby further satisfying the abutment and clamping of aluminum materials of different heights and facilitating the adjustment of the limiting points of the aluminum materials.

[0045] In the specific structure of the first limiting member, the first limiting member includes two first pressure plate bodies 210, which are arranged relatively spaced apart along a first direction. One end of each first pressure plate body 210 is connected to a second slider 220. The mounting base 100 is provided with a second moving groove 130. The first limiting mechanism 200 includes a second drive screw 230, which is movably connected to the second moving groove 130. The second slider 220 is engaged with the second drive screw 230 and the second moving groove 130. The second drive screw 230 can rotate around its own axis to drive the second slider 220 to move along the first direction in the second moving groove 130 and abut against the aluminum material. A second elastic pad 240 is provided at the end of the first pressure plate body 210 near the aluminum material.

[0046] In this embodiment, as Figure 4As shown, the first pressure plate 210 is a rectangular plate structure. Two first pressure plates 210 are arranged at intervals relative to each other along the length direction of the mounting base 100. The lower end of the first pressure plate 210 is movably connected to the mounting base 100. In use, the two first pressure plates 210 can be moved along the length direction of the mounting base 100 and abut against and clamp the two ends of the aluminum material along the length direction, thereby limiting the aluminum material in the length direction. This structure is simple and can be moved according to the length of the transported aluminum material, improving its applicability. A second moving groove 130 is provided at opposite ends of the upper surface of the mounting base 100. The second moving groove 130 is open upward and extends along the length of the mounting base 100. A second drive screw 230 is movably connected in the second moving groove 130 by means of bearings or the like, so that it can rotate around its own axis. One end of the second drive screw 230 extends out of the mounting base 100 and is equipped with an operating handle or a drive device such as a motor, so that it can be driven manually by the operator or by a power device. The second slider 220 is fixedly connected to the lower end of the first pressure plate body 210. Its shape matches the second moving groove 130. The second slider 220 is provided with a threaded hole that mates with the second drive screw 230 and is connected to the second drive screw 230 for transmission. When the second drive screw 230 rotates, the second slider 220 moves along the second moving groove 130 along the length of the mounting base 100, thereby driving the first pressure plate body 210 to move. In addition, a second elastic pad 240 is provided at the end of the first pressure plate 210 near the aluminum material. The second elastic pad 240 can be made of elastic material such as rubber or silicone, which can buffer the pressure of the first pressure plate 210 on the aluminum material and avoid scratches, indentations and other damage to the surface of the aluminum material caused by rigid contact.

[0047] Specifically, one end of the first pressure plate 210 is hinged to the second slider 220. The first pressure plate 210 can rotate relative to the mounting base 100, thus accommodating aluminum materials with different end shapes. After the first pressure plate 210 rotates to the corresponding angle, the first pressure plate 210 and the second slider 220 can be locked relative to each other using existing locking technologies such as locking bolts, preventing them from affecting the clamping and fixing of the aluminum material.
