Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, specifically to a drying kiln unpacking and unpacking device. Background Technology

[0002] In the metal processing industry, taking galvanizing as an example, materials typically undergo cleaning processes such as pickling and washing before hot-dip galvanizing. These processes leave moisture on the material surface. Directly immersing the moist material into molten zinc can cause zinc splattering and may even lead to a dangerous vapor explosion. Therefore, a drying kiln is necessary to heat and dry the metal materials.

[0003] Traditionally, the unpacking process of materials from drying kilns is mostly done manually. However, manual unpacking is relatively inefficient and cannot meet the ever-increasing production demands of production lines. For example, if galvanizing lines 2 and 3 were to use manual unpacking, they could not meet the production requirements of a maximum speed of 3 pieces / minute and a shift output of 1500-1800 pieces. Furthermore, frequent manual unpacking is extremely labor-intensive, easily causing employee fatigue, and prolonged work may lead to physical injuries. In addition, the consistency and accuracy of manual operation are poor, and the unpacking process can easily damage materials, affecting product quality and hindering efficient production and cost control for enterprises.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0031] Traditional unpacking and unpacking processes for drying kilns are mostly done manually, but manual unpacking is relatively inefficient and cannot meet the ever-increasing production demands of the production line.

[0032] This solution provides a drying kiln unpacking and unpacking device. The pickled material 7 is placed on a conveyor chain 12. A motor reducer 14 drives the conveyor chain 12 to transport the material 7 above a lifting mechanism 2. The lifting mechanism 2 then starts lifting, and under the drive of a hydraulic cylinder, it lifts the material 7 to a designated height. The lifting box grabs the material 7 via a drive rod. A traveling trolley 32, driven by a traveling reducer and motor, moves along a linear guide rail, causing the lifting box to transport the material 7 to a flipping mechanism 4. The material 7 is then smoothly transferred to the drying and feeding area 6.

[0033] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0034] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0035] Example 1

[0036] A drying kiln unpacking device, such as Figure 1-5 As shown, it includes a transport mechanism 1 and a transfer mechanism. The transport mechanism 1 is used to transport the material 7 to the transfer mechanism. The transfer mechanism includes a lifting mechanism 2, a transfer mechanism 3 and a flipping mechanism 4. The lifting mechanism 2 is used to lift the material 7 up and down. The transfer mechanism 3 is used to grab the material 7 from the lifting mechanism 2 and transfer it to the flipping mechanism 4. The flipping mechanism 4 is used to place the material 7 stably in the drying and feeding area 6.

[0037] like Figure 1-2 As shown, the transport mechanism 1 is located on one side of the pickling tank 5 and includes several parallel conveyor chains 12. A support frame 11 is fixedly installed on the ground below the conveyor chains 12 to support them. A rotating shaft 13 is fixedly installed at one end of each conveyor chain 12. The rotating shafts 13 are interconnected by a coupling to a motor reducer 14, which drives the conveyor chains 12 to move synchronously, causing the material 7 to move from the pickling tank 5 towards the drying and feeding area 6. A guide plate 8 is also fixedly installed at the end of the conveyor chain 12 near the transfer mechanism 3. During operation, pads are placed on the conveyor chain 12 to prevent damage to the material 7. After the material is transferred, the conveyor chain 12 continues to rotate, causing the pads to fall onto the guide plate 8 under gravity and then onto the pad conveyor belt below (not shown in the figure), achieving automatic pad recycling. In this embodiment, the pad conveyor belt is arranged horizontally and perpendicularly to the conveyor chain 12.

[0038] In this embodiment, the conveyor chain 12 uses two 1.5-inch flat chains, the support frame 11 is made of 120×120×6mm square tubing to ensure structural stability, and the motor reducer 14 is an XWD74-12-4.5KW model to provide power for the operation of the device.

[0039] A lifting mechanism 2 is fixedly installed on the ground near the transfer mechanism 3 between the conveyor chains 12. The lifting mechanism 2 is a loading lifting platform used to lift and lower the material 7. In this embodiment, the loading lifting platform is supported by two sets of hydraulic cylinders, equipped with a 1m wide lifting platform made of steel plate, and has a hydraulic station, which can quickly and stably lift the material 7 and improve the loading speed. The loading lifting platform is existing technology and will not be described in detail here.

[0040] like Figure 1 and Figure 3 As shown, the transfer mechanism 3 includes a frame 31 located on the side of the conveyor chain 12 away from the pickling tank 5. A traveling trolley 32, reciprocating along the transport direction of the material 7, is mounted on the top of the frame 31. A gearbox elevator 33 is fixedly mounted on the traveling trolley 32. A rack drive rod 34, reciprocating vertically, is located inside the gearbox elevator 33. An electromagnet 35 for gripping the material 7 is mounted at the bottom of the drive rod. During operation, the traveling trolley 32 moves above the material 7, the gearbox elevator 33 drives the rack drive rod 34 to fall, and the electromagnet 35 grips the material 7. Then, the rack drive rod 34 returns to its original position, the traveling trolley 32 moves horizontally above the tilting mechanism 4, and the rack drive rod 34 falls, releasing the material 7 onto the receiving part 42, completing one transfer cycle. The traveling trolley 32 and the gearbox elevator 33 are existing technologies and will not be described in detail here. In this embodiment, two or more rack drive rods 34 are installed side by side in the gearbox elevator 33 to ensure stable transfer of material 7. The electromagnet 35 at the bottom of the rack drive rod 34 is 550×240mm in size to ensure that the magnetic force of the suction cup is sufficient to reliably grasp material 7.

[0041] like Figure 4-5 As shown, the flipping mechanism 4 includes a frame 41, which can be fixed in any way. In this embodiment, the frame 41 is composed of square tubes and is fixedly installed between the columns of the frame 31. Several parallel receiving parts 42 are rotatably installed on the top of the frame 41. Each receiving part 42 is equipped with a transition part 43. The receiving part 42 is used to receive the material 7 and transfer the material 7 to the transition part 43 by rotation. The transition part 43 smoothly transfers the material 7 to the drying and feeding area 6 by rotation.

[0042] Specifically, in this embodiment, the rotation points of several receiving members 42 and several transition members 43 are each connected in series via a rotating shaft 13. Two rotating shafts 13 are arranged side-by-side, and the rotating shafts 13 of the receiving members 42 and the transition members 43 are meshed with gears, allowing them to move towards or away from each other. A telescopic member 44 for rotating the receiving member 42 is also hinged to the bottom of the receiving member 42. The end of the telescopic member 44 away from the receiving member 42 is hinged to the lower side of the support frame 11. The flipping mechanism 4 controls the rotation of the receiving member 42 by extending and shortening the telescopic member 44, thereby causing the transition members 43 to move towards or away from the receiving member 42 via gear meshing. That is, the flipping mechanism 4 has two working positions in its rotation stroke: when the telescopic member 44 is extended, it is in the transition position, at which time the receiving member 42 and the transition member 43 rotate towards each other, and the material 7 is transferred from the receiving member 42 to the transition member 43; when the telescopic member 44 is retracted, it is in the receiving position, at which time the receiving member 42 and the transition member 43 move in opposite directions, the receiving surface of the receiving member 42 returns to the initial horizontal state, the transition member 43 rotates towards the drying and feeding area 6, and finally places the material 7 in the drying and feeding area 6.

[0043] In this embodiment, the telescopic member 44 is a cylinder, and the flipping mechanism 4 drives the receiving member 42 to rotate clockwise or counterclockwise by the telescopic movement of the cylinder; the drying and feeding area 6 is a plurality of parallel conveyor chains or conveyor belts, etc. When the transition member 43 rotates toward the drying and feeding area 6, the transition member 43 passes through the gap between the conveyor chains or conveyor belts and is finally located below the drying and feeding area 6, while the material 7 falls into the drying and feeding area 6, and the subsequent material 7 is fed into the drying kiln from the drying and feeding area 6.

[0044] In addition, several extension parts 45 are fixedly installed on the frame 41. The extension parts 45 are not connected to the rotating shaft 13 of the receiving part 42 or the transition part 43. The extension parts 45 extend obliquely downwards to the drying and feeding area 6. The extension parts 45 provide a certain support angle when the transition part 43 transfers the material 7 to the drying and feeding area 6, ensuring the stability and safety of the material 7 falling into the drying and feeding area 6, and avoiding the situation where the equipment in the drying and feeding area 6 jams or locks due to excessive angle.

[0045] The workflow of this solution is as follows: After pickling, material 7 is placed on conveyor chain 12, with a gasket between conveyor chain 12 and material 7. Motor reducer 14 drives conveyor chain 12 to transport material 7 above lifting mechanism 2. Lifting mechanism 2 starts and, driven by a hydraulic cylinder, lifts material 7 to a designated height. The traveling trolley 32 moves above material 7, and gearbox lift 33 drives rack drive rod 34 to fall, where electromagnet 35 grabs material 7. Then rack drive rod 34 resets, and traveling trolley 32 moves horizontally above tilting mechanism 4. Rack drive rod 34 falls and releases material 7 onto receiving part 42. Subsequently, telescopic part 44 extends and retracts sequentially. During extension, receiving part 42 rotates to transfer material 7 to transition part 43. During retraction, transition part 43 descends to transfer material 7. During transfer, material 7 first falls onto extension part 45, and then is smoothly transported from extension part 45 to drying and feeding area 6, completing one cycle of the drying kiln unpacking process. In the next cycle, the conveyor chain 12 continues to rotate, and the pads from the previous cycle fall along the guide plate 8 onto the lower pad transmission belt under the action of gravity, thus realizing the automatic recycling of the pads.

[0046] The above-described preferred embodiments of the present invention are provided for guidance, but it will be apparent to those skilled in the art that such embodiments are provided merely by way of example. Many modifications, alterations, and alternatives will arise in the mind and spirit of the present invention without departing from its intent. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
