Description

Technical Field

[0001] The present invention relates to the technical field of non-ferrous metal smelting automation, and in particular to an automatic conveying and feeding device for zinc blocks in a zinc melting tank. Background Art

[0002] Zinc, as a non-ferrous metal occupying an important position in the modern industrial system, plays an indispensable role in many fields. In the galvanizing industry, zinc can form a dense and corrosion-resistant protective layer on the metal surface, significantly extending the service life of metal products such as steel, and is widely used in fields such as construction, automobile manufacturing, and power facilities; in alloy manufacturing, zinc participates in the synthesis of various alloys, such as brass. By adjusting the proportion of zinc, the strength, hardness, toughness, and processing performance of the alloy can be significantly improved to meet the diverse material requirements of different industrial scenarios; with the continuous advancement of the global industrialization process, the demand for zinc products in various industries is increasing day by day, which also keeps the demand for zinc steadily rising.

[0003] Currently, most of the common automatic conveying and feeding devices for zinc blocks on the market can only achieve the parallel movement and lifting of stacked zinc blocks. Although this transportation mode can quickly deliver a large number of zinc blocks to the zinc melting tank in a short time, it has obvious drawbacks.

[0004] Generally speaking, the stacked zinc blocks are fixed by ropes. For convenience of bundling, multiple zinc blocks are usually horizontally arranged side by side at the bottom to form a zinc block stack. When such a zinc block stack is put into the zinc melting tank for melting, due to its structural characteristics, only the part horizontally arranged at the bottom of the zinc block stack can start melting first, and a large number of zinc blocks in the vertical direction cannot be heated simultaneously. They can only gradually participate in the melting process after the bottom zinc blocks are melted. Since the number of zinc blocks in the vertical direction far exceeds that of the zinc blocks horizontally arranged at the bottom, this leads to an extremely slow overall melting process of the zinc block stack, low melting efficiency, and ultimately it is difficult to achieve an ideal melting effect.

[0005] In addition, the ropes bundling the zinc block stack need to be manually removed before the zinc blocks are put into the zinc melting tank. However, the environment around the zinc melting tank is harsh, with various harmful factors such as high temperature, harmful gases, and dust. When operating manually, workers will be directly exposed to such a dangerous environment, which is very likely to cause serious damage to their physical health. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to provide an automatic conveying and feeding device that can rotate the zinc block stack and remove the bundling ropes.

[0007] The above technical problems are solved by the following technical solutions: The present invention provides an automatic conveying and feeding device for zinc blocks in a zinc melting tank, which includes a hydraulic lifting platform mounted on a rail-type traveling device. The hydraulic lifting platform is used to lift the zinc blocks and move flexibly on the rails to adjust the position and height of the zinc blocks.

A worm gear is coaxially provided on the rod body of the transmission rod on one side of the first mounting plate. The worm gear is meshed with a worm that is rotatably connected to the first mounting plate and the second mounting plate.

Detailed implementation manners

[0040] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below in conjunction with the specific implementation manners and the accompanying drawings.

[0041] The terms used in the present invention are those general terms that are currently widely used in the art in consideration of the functions of the present invention, but these terms may change according to the intentions of those of ordinary skill in the art, precedents or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but based on the meanings of the terms and the overall description of the present invention.

[0042] Referring to Figure 1 , this embodiment provides an automatic zinc block conveying and feeding device for a zinc melting tank, including a hydraulic lifting platform 1, a main clamping mechanism 2, a linkage frame 3, a rotating member 4, a rotation driving mechanism 5 and a lateral auxiliary clamping mechanism 6. The hydraulic lifting platform 1 is mounted on a rail-mounted traveling device. The hydraulic lifting platform 1 is used to lift zinc blocks and move flexibly on the rails to realize the adjustment of the position and height of the zinc blocks.

[0043] In use, the hydraulic lift table 1 and the rail-mounted traveling device connected thereto are both mature products widely used in the market. The hydraulic lift table 1 not only undertakes the task of installing the main clamping mechanism 2 and the linkage frame 3, but also provides a stable and adjustable working platform for the subsequent zinc block conveying and feeding process through its precise lifting and flexible movement along the rail, ensuring the efficient and orderly operation of the entire automatic conveying and feeding device.

[0044] Referring to Figure 1 and Figure 2 , the main clamping mechanism 2 is installed at the bottom of the hydraulic lift table 1. The main clamping mechanism 2 includes a first synchronous component 21 arranged in the horizontal transverse direction. The first synchronous component 21 has two movable ends that can move away from or close to each other. Both movable ends are respectively connected downward with mounting seats 22, and a hydraulic cylinder 23 is arranged between the two mounting seats 22.

[0045] Referring to Figure 1 , Figure 3 and Figure 4 , two linkage frames 3 are respectively fixed at the bottoms of the two mounting seats 22 and are symmetrically arranged.

[0046] Referring to Figure 3 — Figure 7 , two rotating members 4 are arranged on the lower side of the linkage frame 3 and are respectively rotatably connected to the two corresponding linkage frames 3.

[0047] Referring to Figure 3 — Figure 5 , two rotary drive mechanisms 5 are respectively fixed on the outer sides of the two linkage frames 3 and are used to drive the rotatable rotating members 4 to rotate.

[0048] Referring to Figure 6 and Figure 7 , two lateral auxiliary clamping mechanisms 6 are respectively assembled on the two rotating members 4. The lateral auxiliary clamping mechanism 6 includes a second synchronous component 61 arranged in the rotating member 4. The input end of the second synchronous component 61 is connected with a first motor 62, and both movable ends that can move away from or close to each other are fixedly connected with clamping plates 63.

[0049] Referring to Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , two groups of shear-resistant and strengthened supporting plates 7 are symmetrically arranged on the side where the two rotating members 4 are close to each other.

[0050] In use, the zinc block piles are usually assembled in a horizontally interposed manner, and only a small number of zinc blocks are arranged at the bottom, deliberately leaving gaps so that the supporting plates 7 can be smoothly inserted to achieve convenient transportation.

[0051] During operation, first move the hydraulic lifting platform 1 near the zinc block pile to ensure that the zinc block pile is between the two linkage frames 3. Then drive the first synchronization component 21 in the main clamping mechanism 2 to make the two linkage frames 3 move closer to each other, accurately positioning on the left and right sides of the zinc block pile. At the same time, control the lateral auxiliary clamping mechanism 6 to adjust it to the corresponding positions on the front and back sides of the zinc block pile, and start the second synchronization component 61 to push the clamping plate 63 to closely fit the zinc block pile. Immediately afterwards, start the first synchronization component 21 again to smoothly insert the supporting plate 7 at the bottom into the bottom of the zinc block pile, and cooperate with the second synchronization component 61 to initially clamp the zinc block pile on the left and right sides, making full preparations for subsequent transportation.

[0052] Refer to Figure 11 — Figure 13 , when the zinc block pile is transported directly above the zinc melting tank, start the rotary drive mechanism 5 to drive the rotary member 4 to rotate around the linkage frame 3, synchronously driving the zinc block pile to adjust its posture, turning the original zinc block end in the vertical direction downward and aligning it with the bottom of the tank. This adjustment converts the initial horizontal contact of the wide surface of the zinc block into vertical contact of the end, increasing the direct contact quantity between the zinc block pile and the tank body, synchronously expanding the overall heat-receiving area. By changing the traditional single sequence of "melting horizontally at the bottom → layer by layer upward", the zinc blocks in the vertical direction directly contact and melt with the molten liquid in the tank, upgrading from two-dimensional planar melting to three-dimensional stereoscopic melting mode, greatly improving the melting efficiency.

[0053] After completing the angle adjustment, release the constraint between the clamping plate 63 and the linkage frame 3, and the zinc block pile smoothly falls into the zinc melting tank by its own weight. Thereby greatly improving the zinc block melting efficiency and heat energy utilization rate.

[0054] Refer to Figure 1 — Figure 2 , the first synchronization component 21 includes two groups of first chutes 211 opened at the bottom of the hydraulic lifting platform 1 and parallel to each other. Inside each of the two groups of first chutes 211, there is a sliding connection with a suitable slider 212. The bottom of each of the two sliders 212 is connected to a first rack 213 respectively. The bottom of the hydraulic lifting platform 1 is rotationally connected to a first gear 215 through a driving rod 214. The two first racks 213 are symmetrically arranged along the center of the middle driving rod 214 and are meshed with the first gear 215 at the end of the driving rod 214. The two first racks 213 are respectively connected to the corresponding mounting seats 22 at the bottom.

[0055] In use, the two sets of first sliding grooves 211 and the two first racks 213 are also symmetrically distributed around the driving rod 214. When the hydraulic cylinder 23 operates, it drives the two mounting seats 22 to drive the linkage frames 3 to approach each other. At this time, the sliders 212 connected to the tops of the two linkage frames 3 will slide relatively closer within the first sliding grooves 211. At the same time, the first gears 215 and the first racks 213 cooperate with each other in meshing transmission, enabling the two linkage frames 3 to move closer to or away from each other, so that they can move towards or in the opposite direction in the left - right horizontal direction.

[0056] Referring to Figure 3 — Figure 8 , the second synchronization component 61 includes a rotating shaft 611 connected to the output end of the first motor 62. A second gear 612 is coaxially penetrated and connected to the rotating shaft 611. Two sets of second sliding grooves 613 are provided in parallel on the rotating member 4. Corresponding second racks 614 are slidably connected within the two sets of second sliding grooves 613. The two second racks 614 are meshed and connected with the middle second gear 612 and are symmetrically distributed around the center of the second gear 612. The two second racks 614 extend outwards and are connected to the corresponding clamping plates 63.

[0057] Referring to Figure 3 — Figure 6 , a third mounting plate 64 is provided on the rotating member 4. The first motor 62 is fixed on the third mounting plate 64. A bearing seat 615 is fixed on the rotating member 4 on the opposite side of the third mounting plate 64. The rotating shaft 611 is installed within the bearing seat 615.

[0058] In use, the first motor 62 starts and outputs power to drive the rotating shaft 611 to start rotating. Since the rotating shaft 611 is coaxially connected to the second gear 612, the second gear 612 is driven by the rotating shaft 611 to rotate synchronously on the bearing seat 615. At the same time, the two second racks 614 meshed with the second gear 612 will generate corresponding linear motions as the second gear 612 rotates, and the two clamping plates 63 respectively connected to the two second racks 614 move closer to or away from each other, thereby realizing the clamping and fixing or releasing operations in the front - rear direction of the zinc block pile to be transported.

[0059] In addition, the short cross-sectional dimension of the second rack 614 is the same as that of the second chute 613. During the movement of the driving clamping plate 63, the second rack 614 slides within the second chute 613, which can not only accurately guide to ensure the accuracy of the movement trajectory of the clamping plate 63, but also effectively limit its movement range, thereby better ensuring the stability and reliability of the clamping action of the clamping plate 63 on the zinc block stack. In addition, the third mounting plate 64 undertakes the important responsibility of mounting and fixing the first motor 62, providing a stable mounting foundation for the first motor 62 and ensuring its stability during operation. The bearing seat 615 plays the role of mounting and fixing the rotating shaft 611, enabling the rotating shaft 611 to maintain good coaxiality and stability during rotation, providing a solid support for the efficient and accurate operation of the entire clamping mechanism.

[0060] Therefore, the first motor 62 drives the two clamping plates 63 through the second synchronization component 61 to precisely clamp the zinc block stack in the front-rear direction. It not only achieves multi-dimensional stable fixation, but also ensures that when the rotating drive mechanism 5 drives the zinc block stack to adjust the angle, the clamping system can offset the influence of the gravity component force and avoid clamping failure caused by the angle change, thereby ensuring the stable state of the zinc block stack during the rotation process throughout the whole process.

[0061] Refer to Figure 14 , the bottom of the linkage frame 3 is designed as a semi-circular structure and is inserted into the rotating member 4. Rotary table bearings 31 are provided at the insertion junctions on both sides of the semi-circular structure and the rotating member 4. Each rotary table bearing 31 is internally rotatably connected to a rotary table 32, and the two rotary tables 32 and the rotating member 4 are fixedly connected by a transmission rod 33.

[0062] Refer to Figure 3 and Figure 4 , the rotating drive mechanism 5 includes a first mounting plate 51 and a second mounting plate 52 provided on the outer side of the linkage frame 3. A worm gear 53 is coaxially provided on the rod body of the transmission rod 33 on one side of the first mounting plate 51. The worm gear 53 is meshed and connected with a worm 54 rotatably connected to the first mounting plate 51 and the second mounting plate 52. The end of the worm 54 is connected to the output end of a second motor 55 provided on the second mounting plate 52.

[0063] In use, the second motor 55 starts, and its output end drives the worm 54 to rotate. In the worm gear 53 - worm 54 transmission system, the rotation of the worm 54 will drive the meshing worm gear 53 to rotate synchronously. Since the worm gear 53 is arranged on the transmission rod 33, the rotation of the worm gear 53 can drive the rotating member 4 to rotate on the linkage frame 3. At the same time, the zinc block stack clamped on the rotating member 4 will also rotate synchronously, driving the zinc block stack to adjust its attitude synchronously, so that the zinc block end originally in the vertical direction flips downward, aligns with the bottom surface of the zinc melting tank, and changes the contact of the zinc block from the initial horizontal contact of the wide surface to the vertical contact of the end, significantly increasing the direct contact quantity between the zinc block stack and the tank body, expanding the heating area of the zinc block stack, and thus improving the melting efficiency of the zinc block stack.

[0064] The slewing bearing 31 and the turntable 32 can provide more stable support, effectively reducing the shaking and displacement generated during rotation, and greatly improving the stability of the overall structure. When carrying and transporting heavy objects, this stability can ensure that the rotating member 4 always maintains an accurate running track, avoiding the offset of the center of gravity of the heavy object due to shaking, and thus ensuring the safety and smoothness of the transportation process.

[0065] In addition, the worm gear 53 - worm 54 structure has a certain self - locking function. During the rotation of the zinc block stack, affected by gravity and other external interference forces, the worm gear 53 - worm 54 can also effectively prevent the rotating member 4 from slipping downward due to gravity to a certain extent, ensuring that the zinc block stack always maintains a stable state after rotation. With the support of the slewing bearing 31 and the slewing bearing 31, the reliable strength during operation is greatly improved.

[0066] Moreover, compared with the traditional gear transmission structure, this output and bearing method of the worm gear 53 - worm 54 performs better in ensuring the rotation accuracy and quality, providing a solid guarantee for the efficient and accurate attitude adjustment of the zinc block stack in the zinc melting tank.

[0067] Refer to Figure 3 ,, Figure 5 ,, Figure 6 and Figure 13 , on the outer ends of the clamping plates 63, wire harness cutting and material taking assemblies 8 are provided. The wire harness cutting and material taking assembly 8 includes a shear plate 81 and multiple recovery plates 82. The length of the shear plate 81 is slightly longer than that of the recovery plates 82.

[0068] Refer to Figure 9 — Figure 10 , both the shear plate 81 and the recovery plates 82 adopt the structural form of L - shape plus side plates. Their main body is L - shaped, composed of two parallel sides, one of which is shorter and the other is longer, and the outer sides at the junction of the two sides are designed as arcs.

[0069] Refer to Figure 9 —Figure 10 , cutting blocks are provided on the inner sides of two edges of the clipboard 81, and gaps with a gradually decreasing trend are provided on the inner sides of two edges of the recovery plate 82.

[0070] In use, the first synchronization component 21 and the second synchronization component 61 cooperate to push the clamping plate 63 to closely fit on both sides of the zinc block stack. At the same time, the clipboard 81 and the recovery plate 82 are flush with the side of the clamping plate 63 close to the zinc block stack. Moreover, the widths of the clipboard 81 and the recovery plate 82 are smaller than that of the clamping plate 63, and the parts of their outer sides in contact with the rope are designed with an inclined angle and an arc structure, so that the rope for bundling the zinc block stack can be smoothly guided to slide in. With this structure, the clipboard 81 and the recovery plate 82 can be inserted into the inside of the rope more quickly.

[0071] Therefore, when the rope completely crosses the short sides of the clipboard 81 and the recovery plate 82, based on the flexibility and elasticity of the bundling rope itself, the rope will naturally adhere to its long-side structure. After the rotary drive mechanism 5 rotates the zinc block stack into place and places it in the zinc melting tank, the clamping plate 63 starts to reset outward. At this time, the rope will fall into the space between the long and short sides of the clipboard 81 and the recovery plate 82. Since the length of the clipboard 81 is slightly longer than that of the recovery plate 82, the rope will first be stuck in the gradually decreasing gap inside the recovery plate 82, thus achieving preliminary clamping. As the clamping plate 63 continues to reset outward to a certain extent, the rope further moves and enters the space between the long and short sides of the clipboard 81, and then is cut by the cutting block inside the clipboard 81. When the rope is cut, the continuous outward stretching trend will make the rope more deeply embedded in the gap inside the recovery plate 82, so as to recover the cut rope from above the zinc block stack and fix it on the recovery plate 82.

[0072] Through the above process, when the hydraulic lifting platform 1 resets to the initial position with the cut rope, the rope originally used to bundle the zinc block stack has been automatically removed and recovered from the zinc block stack, without manual removal near the zinc melting tank, thus realizing the full-process automation operation inside the zinc melting tank, ensuring the physical health of the operators, and eliminating the threat of a harsh and dangerous environment.

[0073] Finally, it should be pointed out that the methods and devices described in detail above are only examples, and those skilled in the art can modify these examples in different ways as long as they do not depart from the scope of the present invention.
