Description

Technical Field

[0001] This utility model relates to the field of vacuum furnaces, specifically to a feeding mechanism for a vacuum furnace. Background Technology

[0002] A vacuum furnace is a special heating device that can operate in a vacuum to achieve efficient heat transfer. A vacuum furnace typically contains a sealed furnace chamber, which is maintained by the operation of a vacuum system. The vacuum system includes components such as a vacuum pump, vacuum measuring device, and vacuum valves. Before heating the workpieces, which are numerous and heavy, a feeding mechanism is required. The feeding mechanism is used to feed the material into the intended processing position according to the designer's intention, through a stepper motor, belt feeder, cylinder, etc.

[0003] A search revealed a feeding mechanism for a steel vacuum furnace, disclosed in publication number CN213396567U. This mechanism includes a base, a fixed column fixedly mounted on the top of the base, and a support column fixedly connected to the fixed column. The fixed column has an installation groove on its inner side. This feeding mechanism for a steelmaking vacuum furnace, by setting a hopper, first loads a specified amount of material into the hopper. Simultaneously, a servo motor starts rotating forward, driving a screw to rotate. The screw rotation drives a moving block to rise, thereby raising the hopper via a fixed plate. When the hopper reaches the same height as the vacuum furnace, it stops. At this point, an electric push rod extends, causing the left side of the hopper to descend, changing the left side opening of the hopper from an upward tilt to a downward tilt, thus feeding material into the vacuum furnace. The overall structure is simple, can feed material according to the height of the vacuum furnace, prevents material leakage, and achieves controllable feeding volume.

[0004] Existing vacuum furnace feeding mechanisms require different types and heights of vacuum furnaces to be matched with specific feeding mechanisms during use. This not only results in high manufacturing costs but also low reusability. Furthermore, in the comparative case mentioned above, after the feeding mechanism loads the workpiece, the workpiece table in the vacuum furnace needs to be manually removed to align with the workpiece before being pushed back into the vacuum furnace. This manual operation during the process cannot achieve the goal of fully automatic feeding, increasing the labor intensity of workers and reducing the overall usability of the device.

[0005] Therefore, it is necessary to invent a feeding mechanism for a vacuum furnace to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a feeding mechanism for a vacuum furnace. Through an electric slide rail, feeding rack, first turntable, forward feeding support, linkage sleeve, telescopic cylinder, and material pusher, the device achieves automatic feeding and is compatible with most vacuum furnaces. This reduces manual operation during the feeding process, lowers worker workload, and increases the feeding efficiency of the device. It addresses the problem in existing vacuum furnace feeding mechanisms where different types and heights of vacuum furnaces require different matching feeding mechanisms, resulting in high costs and low reusability. Furthermore, in the aforementioned comparative cases, after feeding, the workpiece table in the vacuum furnace needs to be manually removed to align the fed workpiece with the workpiece before pushing it back into the furnace. This manual operation during feeding cannot achieve the fully automatic feeding purpose of this device, increasing worker workload and reducing its overall applicability.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a vacuum furnace, including a feeding base for supporting the feeding assembly;

[0008] The feeding rack is located above the feeding base and is used to lift the workpiece to the same height as the vacuum furnace. An electric slide rail is provided above the feeding base, and an electric sliding sleeve is movably connected to the outside of the electric slide rail.

[0009] A winding frame is fixedly installed inside the feeding frame and is used to carry a linkage turntable to complete the material lifting work. A transmission rod is fixedly installed inside the winding frame. A servo motor is provided at one end of the transmission rod, and a first turntable is fixedly installed at the other end of the transmission rod. A transmission belt is movably connected to the outside of the first turntable, and a second turntable is movably connected to the other side of the transmission belt.

[0010] The linkage sleeve is fixedly installed on the outside of the transmission belt and is used to connect the transmission belt and the feeding assembly. A telescopic cylinder is provided above the linkage sleeve, and a material pusher plate is fixedly installed at one end of the telescopic cylinder.

[0011] Preferably, a vacuum furnace body is provided above the feeding base, and a front insert plate is fixedly installed in front of the feeding base.

[0012] Preferably, a fixing block is fixedly installed on the outside of the feeding base, and a threaded rod passes through the top of the fixing block, with a positioning block fixedly connected to one end of the threaded rod.

[0013] Preferably, the feed rack has a fixed groove on its outside, a fixed slider is fixedly installed inside the fixed groove, and a feed support is fixedly installed at one end of the fixed slider.

[0014] Preferably, the forward feeding tray is movably connected to the feeding frame via a fixed slider, and the fixed slider is configured with a "T" shape.

[0015] Preferably, an upper support plate is provided above the feed tray, and a connecting plate is fixedly installed on one side of the upper support plate.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model is equipped with an electric slide rail, a feeding rack, a first turntable, a forward feeding tray, a linkage sleeve, a telescopic cylinder, and a material pusher plate. When using this device with different vacuum furnaces for feeding, there is no need to match or manufacture a matching feeding mechanism according to the requirements of the vacuum furnace. The feeding base can be directly inserted into the bottom of the vacuum furnace through rollers, so that the device is close to the feeding port of the vacuum furnace. Then, the first turntable and the second turntable on the feeding rack operate in linkage, so that the transmission belt drives the forward feeding tray to lift the workpiece to be heated to the feeding port of the vacuum furnace to complete the workpiece loading. Then, without manually pulling the worktable in the vacuum furnace, the forward feeding tray and the workpiece can be driven into the vacuum furnace through the electric slide rail. Then, with the help of the telescopic cylinder and the material pusher plate, all the workpieces on the upper tray are pushed into the vacuum furnace, completing the automatic feeding of the vacuum furnace. This combination not only allows the device to meet the purpose of automatic feeding, but also adapts to most vacuum furnaces, reduces the manual operation part in the feeding process, reduces the labor intensity of workers, and also speeds up the feeding efficiency of the device for vacuum furnaces.

[0018] 2. This utility model is equipped with a fixed block, a threaded rod, a positioning block, a feeding frame, a fixed slide groove, a fixed slider, and a forward feeding support. When using this device with different vacuum furnaces for feeding, the threaded rod can be twisted to lower the positioning block, making the feeding base more stable when matched and installed with different vacuum furnaces, reducing shaking or errors during the feeding process. Then, the first turntable on the feeding frame operates in conjunction with the first turntable, driving the forward feeding support to lift the workpiece to the inlet of the vacuum furnace. The fixed slide groove and the fixed slider can limit the upward trajectory of the forward feeding support, allowing the forward feeding support to rise stably on the prescribed trajectory to complete the feeding work.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-5 The feeding mechanism for a vacuum furnace shown includes a feeding base 1 for supporting the feeding assembly;

[0029] The feeding rack 9 is located above the feeding base 1 and is used to lift the workpiece to the same height as the vacuum furnace. An electric slide rail 7 is provided above the feeding base 1, and an electric sliding sleeve 8 is movably connected to the outside of the electric slide rail 7.

[0030] The winding frame 10 is fixedly installed inside the feed frame 9 and is used to carry the linkage turntable to complete the material lifting work. The winding frame 10 has a transmission rod 11 fixedly installed inside. One end of the transmission rod 11 is equipped with a servo motor 12, and the other end of the transmission rod 11 is fixedly installed with a first turntable 13. The outside of the first turntable 13 is movably connected to a transmission belt 14, and the other side of the transmission belt 14 is movably connected to a second turntable 15.

[0031] The linkage sleeve 21 is fixedly installed on the outside of the transmission belt 14 and is used to connect the transmission belt 14 and the feeding assembly. A telescopic cylinder 22 is provided above the linkage sleeve 21. A material pusher plate 23 is fixedly installed at one end of the telescopic cylinder 22. The electric slide rail 7 drives the feed tray 18 and the workpiece into the vacuum furnace. Then, in conjunction with the telescopic cylinder 22 and the material pusher plate 23, all the workpieces on the upper tray 19 are pushed into the vacuum furnace, completing the automatic feeding operation of the vacuum furnace.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a vacuum furnace body 2 is installed above the feeding base 1, and a front insert plate 3 is fixedly installed in front of the feeding base 1. There is no need to match or manufacture a matching feeding mechanism according to the requirements of the vacuum furnace; the feeding base 1 can be directly inserted into the bottom of the vacuum furnace via rollers, allowing the device to be close to the inlet of the vacuum furnace for use with different vacuum furnaces. A fixing block 4 is fixedly installed on the outside of the feeding base 1, and a threaded rod 5 passes through the top of the fixing block 4. A positioning block 6 is fixedly connected to one end of the threaded rod 5. The positioning block 6 can be lowered by twisting the threaded rod 5, making the feeding base 1 more stable when matched with different vacuum furnaces, reducing shaking or errors during the feeding process. A fixing groove 16 is opened on the outside of the feeding rack 9, and a fixing slider 17 is fixedly installed inside the fixing groove 16. A forward feeding support 18 is fixedly installed at one end of the fixing slider 17. The fixing groove 16 and the fixing slider 17 can limit the upward trajectory of the forward feeding support 18, allowing the forward feeding support 18 to rise stably along the predetermined trajectory to complete the feeding work.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the forward feeder 18 is movably connected to the feed rack 9 via a fixed slider 17. The fixed slider 17 has a "T"-shaped structure. The overall structure of the fixed slider 17 is simple and easy to operate. If a fault occurs, it is convenient for maintenance personnel to replace and repair it in a timely manner without delaying the normal use of the device. An upper support plate 19 is provided above the forward feeder 18. A connecting plate 20 is fixedly installed on one side of the upper support plate 19. The operation of the upper support plate 19 is simple. It can be used according to the current feeding requirements of the workpieces. If there are many small workpieces, the upper support plate 19 can be installed to allow the feeding of many small workpieces to be completed on the upper support plate 19.

[0034] The working principle of this utility model is as follows: First, connect the external power supply. There is no need to match or manufacture a feeding mechanism according to the requirements of the vacuum furnace. The feeding base 1 can be directly inserted into the bottom of the vacuum furnace via rollers, bringing the device close to the furnace's inlet. Then, twist the threaded rod 5 to lower the positioning block 6, making the feeding base 1 more stable when installed with different vacuum furnaces, reducing shaking or errors during the feeding process. Next, take out the workpieces to be fed. For numerous small workpieces, the upper pallet 19 can be installed to support the large number of small workpieces. For workpieces that are large in volume but small in quantity, the feeding process is completed on feed rack 19. Conversely, for workpieces that are large in volume but small in quantity, they can be directly placed on feed tray 18 for direct upward feeding. After the workpiece is placed, the servo motor 12 can be turned on. The servo motor 12 drives the first turntable 13 to rotate via transmission rod 11. Then, the first turntable 13 and the second turntable 15 on feed rack 9 operate in conjunction, causing the transmission belt 14 to connect to feed tray 18 via linkage sleeve 21. This causes feed tray 18 to lift the workpieces that need to be heated to the feed port of the vacuum furnace, completing the workpiece feeding process. The feeding process begins with the fixed slide 16 and fixed slider 17 restricting the upward trajectory of the feed tray 18 as the workpiece rises. This allows the feed tray 18 to rise steadily along the predetermined trajectory, completing the feeding process. After the workpiece is lifted to the inlet of the vacuum furnace, the switch of the electric slide rail 7 is turned on. The electric slide rail 7 then drives the feed tray 18 and the workpiece into the vacuum furnace. In conjunction with the telescopic cylinder 22 and the material pusher 23, all the workpieces on the upper tray 19 are pushed into the vacuum furnace, completing the automatic feeding process. This not only fulfills the purpose of automatic feeding but also adapts to most vacuum furnaces, reducing the manual operation during the feeding process. The workpieces entering the vacuum furnace can be processed normally, and then the device can be operated again for the next batch of automatic workpiece feeding. Finally, after completing the installation and use of the entire vacuum furnace feeding mechanism according to the above operations, the switch of the electric slide rail 7 and the switch of the servo motor 12 are turned off. If the device is not used for a long time, the external power supply can be disconnected. This completes the use of the vacuum furnace feeding mechanism.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
