Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

Therefore, the above terms should not be understood as limiting the present invention.

[0027] In the description of the utility model, if there is a word description such as "several", it means one or more, and the meaning of "more" is two or more. Greater than, less than, and more than are understood to exclude the number itself, and above, below, and within are understood to include the number itself. If there is a description of the first, second, and third, it is only used to distinguish the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0028] The following is combined with Figure 1-5 , an embodiment of a raw material conveying device for an annealing furnace of the utility model is further described in detail.

[0029] A raw material conveying device for an annealing furnace, such as Figure 1 , 2 As shown, it includes a fixed conveying platform 1 for stably conveying materials, a telescopic conveying platform 2 slidably connected to the fixed conveying platform 1, and an extension conveying platform 3 arranged in the telescopic conveying platform 2. The telescopic conveying platform 2 can be telescoped back and forth along the length direction of the fixed conveying platform 1, and the extension conveying platform 3 can be further extended outward along the telescopic conveying platform 2; the heights of the fixed conveying platform 1, the telescopic conveying platform 2 and the extension conveying platform 3 decrease successively, and the telescopic conveying platform 2 is movably connected with a material receiving plate 4 at the connection between the fixed conveying platform 1 and the extension conveying platform 3, and the material receiving plate 4 is arranged to be tilted downward; a lifting bracket 5 is arranged at the bottom of the fixed conveying platform 1, and the lifting brackets are respectively fixedly connected to the two ends of the fixed conveying platform 1, and a lifting drive component 6 for driving the fixed conveying platform 1 to move up and down is arranged on the lifting bracket 5.

[0030] Specifically, in the process of conveying raw materials, due to the different volumes and heights between different annealing furnaces, different annealing furnaces are usually equipped with conveying devices adapted thereto, which not only leads to high production costs, but also leads to a narrow scope of application of the conveying device. Therefore, in the utility model, the telescopic conveying platform 2 and the extension conveying platform 3 are integrated into the fixed conveying platform 1, so as to extend the conveying length of the conveying device in the horizontal direction, and at the same time, the lifting height of the conveying device is controlled by the lifting bracket 5 supported by the bottom, so that the height position can be adjusted according to the annealing furnaces of different heights, thereby improving its transportation efficiency; and in the process of conveying raw materials, since the heights between the fixed conveying platform 1, the telescopic conveying platform 2 and the extension conveying platform 3 decrease successively, in order to avoid the situation where the raw materials are bumped at their connection positions due to the height difference, a material receiving plate 4 is arranged at their connection positions, and the material receiving plate 4 can not only act as a buffer, but also limit the telescopic distance of the telescopic conveying platform 2 and the extension conveying platform 3, thereby ensuring the stability of the materials during transportation, and further reducing the difficulty of manual operation.

[0031] In order to further improve the automated operation of the conveying device, a control system may be provided on the conveying device. The control system includes a control panel and a control unit. The control panel is used to receive operating instructions input by the user. The control unit controls the telescopic movement of the telescopic conveying platform 2 and the extension conveying platform 3 and the operation of the lifting drive assembly 6 according to the operating instructions. The control unit may adopt a control chip such as a PLC (programmable logic controller) or a microprocessor to achieve precise control of the device. Through the control system, the user can conveniently set conveying parameters, start and stop conveying and other operations through the control panel. The control unit generates control instructions according to the set parameters and sends them to the conveying device, thereby enabling fully automated feeding to reduce manual labor intensity and save production costs.

[0032] In this embodiment, if Figure 3 As shown, the lifting drive assembly 6 includes a lifting cylinder 61, a lifting shaft 62 and a locking member 63. The lifting cylinder 61 is fixedly connected to the lifting bracket 5, and the output end of the lifting cylinder 61 is transmission-connected to the lifting shaft 62. The lifting shaft 62 is inserted into the lifting bracket 5, and one end of the lifting shaft 62 is fixedly connected to the fixed conveying platform 1; the locking member 63 is arranged at the telescopic connection of the lifting shaft 62, and is used to clamp the extended length of the telescopic shaft.

[0033] Specifically, when the fixed conveyor platform 1 is adjusting its height, the lifting cylinder 61 drives the lifting shaft 62 to move up and down along the lifting bracket 5. At the same time, after being raised or lowered to a suitable height, the locking member 63 is automatically clamped on the lifting bracket 5, so that the position of the lifting shaft 62 is fixed; thereby, it can adapt to annealing furnaces of different heights. The purpose of setting the lifting bracket 5 is not only to facilitate the lifting control, but also to provide stable support for the fixed conveyor platform 1.

[0034] Since the telescopic conveyor platform 2 and the extended conveyor platform 3 are not provided with a supporting structure, in order to avoid the unstable center of gravity of the telescopic conveyor platform 2 and the extended conveyor platform 3 after extending the maximum stroke, configuration blocks can be set on both sides of the fixed conveyor platform 1 to reinforce its center of gravity, or a heavier and more load-bearing lifting bracket 5 can be used for support.

[0035] In this embodiment, if Figure 2 As shown, the fixed conveyor platform 1, the telescopic conveyor platform 2 and the extended conveyor platform 3 are all provided with a sliding assembly 7 for adjusting the conveying length in the horizontal direction, and a transmission power assembly 8 for driving the telescopic conveyor platform 2 and the extended conveyor platform 3 to rotate and extend. The transmission power assembly 8 is connected to the sliding assembly 7 through a chain drive to realize the telescopic conveyor platform 2 and the extended conveyor platform 3 to transport materials.

[0036] Specifically, the transmission power assembly 8 includes a driving motor 71, an active roller 72 and a driven roller group 73. The driving motor 71 is located below the fixed conveyor platform 1, the active roller 72 is located above the driving motor 71, and both ends of the active roller 72 are rotatably connected to the inner side wall of the fixed conveyor platform 1. There are multiple driven roller groups 73, and the multiple driven roller groups 73 are respectively arranged at both ends of the fixed conveyor platform 1, the telescopic conveyor platform 2 and the extended conveyor platform 3, and the driven roller groups 73 are respectively connected to the active roller 72 and the driving motor 71 through chain transmission.

[0037] In order to improve the precision of controlling the sliding stroke of the sliding assembly 7, when controlling the sliding assembly 7 to slide, the driving motor 71 of the transmission power assembly 8 controls the active roller 72 to rotate through chain transmission, and then the sprocket and chain are also used for transmission between the active roller 72 and the driven roller group 73. When the driven roller group 73 rotates, it simultaneously drives the telescopic conveyor platform 2 and the extension conveyor platform 3 to perform telescopic movement through the sliding assembly 7; wherein, the selection of the driving motor 71 should be determined according to the working requirements and load conditions of the conveying device, and the transmission method between the driving motor 71 and the active roller 72 and the driven roller group 73 can adopt other transmission methods with the same effect in addition to chain transmission, which is not limited here.

[0038] The coordinated operation of the drive device and the control system ensures the smooth movement and precise control of the telescopic conveying mechanism; the design of the supporting structure enables the device to stably support the telescopic conveying mechanism.

[0039] In this embodiment, the sliding assembly 7 includes a bidirectional slide rail 81 for sliding the telescopic conveyor platform 2 and the extension conveyor platform 3, a pulley group 82 slidably connected to the bidirectional slide rail 81, and a travel switch 83 for controlling the telescopic stroke. The bidirectional slide rail 81 is arranged in parallel with an upper and lower offset, and limit blocks 84 are arranged at both ends of the bidirectional slide rail 81; the pulley group 82 is rotatably connected to one end of the telescopic conveyor platform 2 and the extension conveyor platform 3, and the pulley group 82 can slide along the upper and lower sides of the bidirectional slide rail 81; the travel switch 83 is arranged at the other end of the telescopic conveyor platform 2 and the extension conveyor platform 3.

[0040] Specifically, the telescopic rod and the telescopic sleeve can be slidably matched, and the conveying length can be adjusted by the telescopic movement of the telescopic rod. The design of the telescopic conveying mechanism enables the device to flexibly adjust the conveying length according to the height of the annealing furnace and the conveying requirements of the raw materials.

[0041] In this embodiment, a support bracket 9 is further provided at one end of the fixed conveying platform 1 . The support bracket 9 is used to carry the driving motor 71 , and the support bracket 9 is fixedly connected to the bottom of the fixed telescopic platform.

[0042] Specifically, the purpose of setting the support frame 9 is to facilitate the fixation of the driving motor 71, wherein the support frame 9 is a basin-shaped structure fixed on the bottom end of the fixed conveying platform 1. At the same time, it is also convenient to disassemble and assemble the support frame to replace or maintain the driving motor 71, making its subsequent maintenance work easier and faster, greatly improving the practicality of the conveying device.

[0043] In this embodiment, if Figure 5 As shown, a plurality of support plates 10 are arranged inside the fixed conveyor platform 1, the telescopic conveyor platform 2 and the extended conveyor platform 3. The plurality of support plates 10 are equidistantly arranged at the bottom of the bidirectional slide rail 81, and a guide roller 11 is fixedly connected to one side of the support plate 10 through an angle code.

[0044] Specifically, the support plate 10 is used to fix and support the bidirectional slide rail 81, and a guide roller 11 is provided on one side thereof to provide a guide for the telescopic conveyor platform 2 and the extension conveyor platform 3 to facilitate the telescopic process.

[0045] In this embodiment, if Figure 4 As shown, the ends of the telescopic conveying platform 2 and the extending conveying platform 3 are both provided with limiting strips 12 for engaging with the receiving plate 4 .

[0046] Specifically, the limit bar 12 can be used to limit the maximum travel distance of the telescopic conveyor platform 2 and the extended conveyor platform 3 during the extension and retraction process, thereby avoiding the risk of falling. At the same time, the limit bar 12 can also be engaged with the feeding plate, thereby fixing the receiving plate 4, so that the raw materials can be stably delivered when they are conveyed to the receiving plate 4, further improving the stability of the conveying device.

[0047] The working principle of this utility model:

[0048] After starting the device, first, the fixed conveyor platform 1 is lifted and lowered according to the height of the furnace door opening of the annealing furnace, and the lifting drive component 6 is used to control the lifting bracket 5 to lift up and down, so as to meet the conveying height of the fixed conveyor platform 1; at the same time, the fixed conveyor platform 1 controls the telescopic conveyor platform 2 and the extension conveyor platform 3 to perform telescopic movement under the drive of the transmission power component 8. During the telescopic process, the sliding component 7 drives the sliding stroke of the telescopic conveyor platform 2 and the extension conveyor platform 3 according to the control instruction, and then accurately controls the extension length, so as to facilitate the conveying of raw materials into the annealing furnace; during the conveying process, the telescopic position and state of the telescopic conveyor platform 2 and the extension conveyor platform 3 are monitored in real time by the control system to ensure that the material remains stable during the conveying process, and when the raw materials pass through the telescopic conveyor platform 2 and the extension conveyor platform 3 with different height differences, the material receiving plate 4 can act as a slope for buffering. If an abnormal situation occurs, the control system can respond in time and take corresponding measures, such as adjusting the conveying speed, stopping the conveying, etc., so as to achieve efficient and flexible raw material transportation.

[0049] The utility model provides a liftable lifting bracket 5 on the top of the fixed conveying platform 1, so that the fixed conveying platform 1 can be adjusted according to annealing furnaces of different heights to adapt to different working environments, thereby improving its applicability and flexibility; at the same time, a telescopic conveying platform 2 and an extension conveying platform 3 are provided in the fixed conveying platform 1, so as to further extend the conveying length of the conveying device in the horizontal direction; the device not only improves production efficiency and reduces labor intensity, but also has wide applicability and flexibility; with the continuous development of industrial automation technology, such devices are expected to be more widely used in future industrial production.
