DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the technical solutions of the embodiments of the present application, the following will briefly introduce the drawings needed to be used in the embodiments. Obviously, the drawings described in the following are some embodiments of the present application, and other drawings can also be obtained by those skilled in the art without any creative effort on the basis of these drawings.

[0024] Please refer to Figures 1 to 3The feeding device of the high-temperature vacuum sintering furnace comprises a driving motor 10, a horizontal transmission mechanism 20, a horizontal conveying mechanism 30 and a lifting mechanism 40, wherein the driving motor 10 is located outside the furnace body, the horizontal transmission mechanism 20 is located inside the furnace body, one end of the horizontal transmission mechanism 20 penetrates through the side wall of the furnace body and is detachably connected with the rotating shaft of the driving motor 10, the other end of the horizontal transmission mechanism 20 is connected with the horizontal conveying mechanism 30 and can drive the horizontal conveying mechanism 30 to move along the axial direction of the furnace body, the horizontal conveying mechanism 30 is further connected with the lifting mechanism 40 in a clamping mode, the horizontal conveying mechanism 30 can be relatively extended and contracted with the lifting mechanism 40, and the bottom of the lifting mechanism 40 is provided with a top rod 404, and the top rod 404 of the lifting mechanism 40 penetrates through the bottom of the furnace body and is connected with a lifting driving device outside the furnace body.

[0025] The horizontal transmission mechanism 20 is used for transferring the workpiece from one furnace body to another furnace body. The furnace body is generally provided with a bracket for placing the workpiece. When the workpiece is transferred from one bracket to another bracket, the workpiece needs to be lifted in addition to horizontal movement, so as to facilitate the transfer of the workpiece from the bracket to the horizontal transmission mechanism 20 or the transfer of the workpiece from the horizontal transmission mechanism 20 to the bracket. Therefore, when the feeding device of the high-temperature vacuum sintering furnace is operated, the driving motor 10 is used to drive the horizontal transmission mechanism 20 to move to the position directly below the workpiece, then the lifting mechanism 40 is used to drive the horizontal transmission mechanism 20 to ascend to the position in contact with the workpiece and finally to make the workpiece separate from the bracket, then the driving motor 10 is used to drive the horizontal transmission mechanism 20 to move to the position directly above the bracket of another furnace body, and then the lifting mechanism 40 is used to drive the horizontal transmission mechanism 20 to descend to the position in contact with the workpiece and finally to make the workpiece separate from the horizontal transmission mechanism 20.

[0026] In a preferred embodiment, the lifting driving device is a screw rod lifter, and the lifting screw rod of the screw rod lifter is fixedly connected with the top rod 404.

[0027] In another preferred embodiment, the lifting driving device is a hydraulic rod, and the telescopic rod of the hydraulic rod is fixedly connected with the top rod 404.

[0028] The horizontal conveying mechanism 30 is further connected with the lifting mechanism 40 in a clamping mode. In a preferred embodiment, the horizontal conveying mechanism 30 and the lifting mechanism 40 are provided with matched clamping grooves and clamping blocks, and the direction of the clamping grooves is the moving direction of the horizontal conveying mechanism 30. For example, the two sides of the horizontal conveying mechanism 30 and the lifting mechanism 40 are provided with I-shaped steel or channel steel, and the side edges of the I-shaped steel or channel steel can be used as the clamping grooves. In order to reduce the resistance during movement, rollers can be arranged to be connected with the clamping grooves in a clamping mode. In another preferred embodiment, the horizontal conveying mechanism 30 and the lifting mechanism 40 are provided with matched sleeve rods and sleeves, so that the horizontal conveying mechanism 30 can move along the axial direction of the furnace body through the sleeve rod and sleeve mode.

[0029] Further, the horizontal transmission mechanism 20 comprises a transmission shaft 201, two symmetrical and parallel transmission assemblies 202, one end of the transmission shaft 201 is detachably connected with the rotating shaft of the driving motor 10, the other end of the transmission shaft 201 is connected with the transmission assembly 202, the horizontal conveying mechanism 30 and the lifting mechanism 40 are located between the two transmission assemblies 202, the transmission assembly 202 comprises a transmission gear 2021, two supporting gears 2022, a transmission chain 2023, a slide 2024 and a slide cable 2025, the transmission gear 2021 is connected with the transmission shaft 201 in a sleeved manner, the transmission shaft 201 drives the transmission gear 2021 to rotate, the supporting gears 2022 are located below the transmission gear 2021 on both sides and are located on the same horizontal line, the transmission chain 2023 is connected with the transmission gear 2021 and the supporting gears 2022 in a meshing manner, the slide 2024 is located below the transmission chain 2023, the upper end of the slide cable 2025 is fixedly connected with the transmission chain 2023, the lower end of the slide cable 2025 is connected with the slide 2024 in a sleeved manner, and the side end of the slide cable 2025 is connected with the horizontal conveying mechanism 30.

[0030] The transmission assembly 202 is used for transmitting power to the horizontal conveying mechanism 30, the transmission assembly 202 is located on both sides of the horizontal conveying mechanism 30, and the driving motor 10 drives the two transmission assemblies 202 to rotate synchronously. When the two supporting gears 2022 on the transmission assembly 202 are on the same horizontal line, the transmission chain 2023 between the supporting gears 2022 is always in a horizontal state. The slide cable 2025 moves between the two supporting gears 2022, and the stress of the slide cable 2025 can be kept horizontal. In order to ensure that the slide cable 2025 can move horizontally, the slide 2024 is arranged below the slide cable 2025, the slide 2024 can guide the slide cable 2025 to move horizontally and can also provide stable support force. The horizontal conveying mechanism 30 is pulled by one slide cable 2025 on each side, and the horizontal conveying mechanism 30 moves more stably.

[0031] The transmission gear 2021, the two supporting gears 2022, the transmission chain 2023, the slide 2024 and the slide cable 2025 are high-temperature-resistant metal products, including but not limited to ferrous alloy. Since the transmission chain 2023 is a metal product, the weight is relatively heavy, and it is easy to relax, thereby causing problems such as chain falling off. Therefore, further, the horizontal transmission mechanism 20 further comprises a tensioning wheel 2026, the tensioning wheel 2026 is connected with the transmission chain 2023 in a meshing manner, and the tensioning wheel 2026 is located between the transmission gear 2021 and the supporting gear 2022. Through the action of the tensioning wheel 2026, the transmission chain 2023 can be in a tight state.

[0032] Further, the transmission shaft 201 is connected with the rotating shaft of the driving motor 10 through a first connecting piece 50, and the first connecting piece 50 is a shaft coupling. The transmission shaft 201 and the driving motor 10 are connected through the shaft coupling, so that the transmission shaft 201 and the driving motor 10 can be conveniently disassembled. Especially, the transmission shaft 201 is located in the furnace body and is affected by high temperature of the furnace body for a long time, so that the transmission shaft 201 needs to be regularly maintained. When disassembling, the shaft coupling only needs to be disassembled.

[0033] Further, the sliding rope 2025 is connected with the horizontal conveying mechanism 30 through a second connecting piece 60, the first end of the second connecting piece 60 is provided with a pin hole, and the sliding rope 2025 is provided with a pin seat correspondingly. The sliding rope 2025 is pinned with the first end of the second connecting piece 60, the second end of the second connecting piece 60 is connected with the horizontal conveying mechanism 30 in up and down sliding mode, and correspondingly, the two sides of the horizontal conveying mechanism 30 are respectively provided with two vertical guide rods 302. The two vertical guide rods 302 on the same side are spaced apart, the second end of the second connecting piece 60 is located in the interval between the two vertical guide rods 302, and the width of the second end of the second connecting piece 60 is less than the interval between the vertical guide rods 302, so that the second end of the second connecting piece 60 can slide up and down in the interval. The horizontal conveying mechanism 30 is driven by the lifting mechanism 40 to move up and down, but the sliding rope 2025 is fixed on the sliding way 2024 and cannot move up and down. Therefore, the sliding rope 2025 is connected with the horizontal conveying mechanism 30 through the second connecting piece 60. When the horizontal conveying mechanism 30 moves in the vertical direction, the second end of the second connecting piece 60 relatively slides with the horizontal conveying mechanism 30 in the vertical direction, and the second connecting piece 60 does not slide up and down. However, when the sliding rope 2025 moves horizontally, the second end of the second connecting piece 60 can drive the quartz conveying guide rail to move horizontally.

[0034] Further, the horizontal conveying mechanism 30 comprises a horizontal guide rail 301, four vertical guide rods 302 and pulleys 303. The two sides of one end of the horizontal guide rail 301 are respectively provided with two vertical guide rods 302, the other end of the horizontal guide rail 301 is provided with a material table, the sintered materials are placed on the material table, the two sides of the horizontal guide rail 301 are provided with pulleys 303, and correspondingly, the two sides of the lifting mechanism 40 are provided with sliding grooves. The pulleys 303 move in the sliding grooves.

[0035] In a preferred embodiment, the horizontal guide rail 301 comprises an inner guide rail 3011 and an outer guide rail 3012, and the inner guide rail 3011 is slidingly connected with the outer guide rail 3012. The horizontal guide rail 301 is provided in two sections, which helps to improve the load bearing strength of the horizontal guide rail 301. If the horizontal guide rail 301 is provided in one section, the stress on the end of the guide rail is relatively large because the guide rail is relatively long and the material is only placed on one end of the guide rail. However, when the horizontal guide rail 301 is provided in two sections, the length of the guide rail is shortened, and the stress on the end of the guide rail is greatly reduced. Specifically, the outer side of the inner guide rail 3011 is provided with a pulley 303, and the inner side of the outer guide rail 3012 is provided with a sliding groove. The main body of the inner guide rail 3011 is composed of two I-beams, and the I-beams are connected by a plurality of parallel rod bodies. The I-beams are further provided with limiting blocks 30111, and the material is placed between the limiting blocks 30111. Please refer to Figure 4 The main body of the outer guide rail 3012 is composed of two channel steels. The inner side of the channel steels is provided with a front limiting baffle 30121 and a rear limiting baffle 30122. In this way, when the inner guide rail 3011 moves forward to the front limiting baffle 30121, further movement can drive the outer guide rail 3012 to move forward synchronously. Similarly, when the inner guide rail 3011 moves backward to the rear limiting baffle 30122, further movement can drive the outer guide rail 3012 to move backward synchronously. The outer side of the channel steels is further provided with the pulley 303, and the pulley 303 can slide in the sliding groove of the lifting mechanism 40.

[0036] In another preferred embodiment, the middle part of the material table of the inner guide rail 3011 is further provided with a material groove, and the material groove is located between the two I-beams. The broken material falling from the material can be collected by the material groove, thereby preventing the material from falling into the sliding groove and interacting with the pulley 303, thereby causing relatively large abrasion.

[0037] Further, the lifting mechanism 40 comprises a horizontal guide frame 401, two lateral support assemblies 402, a support shaft 403, a top rod 404, a vertical guide rail wheel set 405, and a vertical guide rail 406. The bottom of the two sides of the horizontal guide frame 401 is connected with one lateral support assembly 402, respectively. The two ends of the support shaft 403 are connected with the lateral support assemblies 402. The middle part of the support shaft 403 is connected with the upper end of the top rod 404. The vertical guide rail wheel set 405 is distributed on the two sides of the horizontal guide frame 401. The vertical guide rail 406 is clamped on the vertical guide rail wheel set 405. The vertical guide rail wheel set 405 can move on the vertical guide rail 406. The lower end of the vertical guide rail 406 is fixedly connected with the inner wall of the furnace body.

[0038] The vertical guide rail wheel set 405 is two fixed pulleys 303 on the horizontal guide frame 401, the inner side of the fixed pulley 303 is close to the vertical guide rail 406, when the top rod 404 drives the horizontal guide frame 401 to move upward, the fixed pulley 303 moves along the vertical guide rail 406, thus, the vertical guide rail 406 can provide stable guiding force for the horizontal guide frame 401, so that the horizontal guide frame 401 can move smoothly upward. At the same time, the two lateral support assemblies 402 also move upward synchronously.

[0039] Further, the lateral support assembly 402 includes two cross arranged support rods 4021, support wheels 4022, the two support rods 4021 are hinged, the support shaft 403 is located at the intersection of the two support rods 4021 and is rotationally connected with the support rod 4021, the support wheel 4022 is located at the two ends of the support rod 4021, the two sides of the horizontal guide frame 401 are provided with limiting grooves, the support wheel 4022 is located in the limiting groove and can move horizontally in the limiting groove.

[0040] In addition, in another preferred embodiment, the limiting groove can also be in sliding connection with the horizontal guide frame 401, in this case, the support wheel 4022 does not need to move horizontally in the limiting groove, when the support wheel 4022 moves horizontally, it drives the limiting groove to move synchronously, and slides relative to the horizontal guide frame 401.
