Description

Technical Field

[0001] This utility model belongs to the field of annealing furnace technology, specifically a feeding device for an annealing furnace. Background Technology

[0002] Annealing is a heat treatment process mainly used for metallic materials. Through heating, holding, and slow cooling, the internal structure of the material is adjusted, thereby improving its properties. Annealing is widely used in steel, non-ferrous metals, and their alloys. Its purpose is to reduce hardness, increase plasticity, eliminate internal stress, refine grains, and improve processing performance. Annealing furnaces are indispensable processing equipment in annealing. Generally, there are two methods: materials are directly fed into the annealing furnace manually or by a feeding device. Manual feeding is inefficient and poses a risk of burns due to the high temperature of the annealing furnace. In addition, the existing feeding devices for annealing furnaces are prone to misalignment and disorder during the feeding process, which can cause the steel pipes to become stuck at the furnace inlet. Utility Model Content

[0003] The purpose of this utility model is to provide a feeding device for an annealing furnace to solve at least one aspect of the problems and defects mentioned in the background art.

[0004] A feeding device for an annealing furnace includes a conveyor table, a movable component installed on the top of the conveyor table along the conveying direction, a platform installed on the top of the movable component, and a pushing device installed on the platform, with the pushing part of the pushing device facing the end of the conveyor table. Fixed plates are installed on both sides of the platform, extending away from the conveyor. A control block and a movable plate are provided at the end of the platform near the end of the conveyor. The control block is installed at the end of the platform, and the movable plate is movably connected to the control block and can be rotatably installed at the end of the platform through the control block.

[0005] Furthermore, the pushing device includes a pushing cylinder and a pushing plate. The pushing cylinder is installed at one end of the platform, and the pushing part of the pushing cylinder is set towards the end of the conveyor platform. The pushing plate is horizontally set on the top of the platform and is connected to the telescopic part of the pushing cylinder.

[0006] Furthermore, the moving component includes a slide rail, a rotary motor, and a lead screw. The slide rail is installed on the top of the conveyor table and is arranged along the conveying direction. A slider is installed on the slide rail, and a platform is installed on the slider. The rotary motor is installed at one end of the conveyor table, and a support block is installed at the other end of the conveyor table. One end of the lead screw is connected to the rotary motor, and the other end is rotatably installed on the support block. A nut is fixedly installed at the bottom of the platform, and the lead screw is screwed to the nut.

[0007] Furthermore, it also includes a feeding ladder, which is installed next to the conveyor table via a support assembly. The discharge end of the feeding ladder is lower than the infeed end in terms of horizontal height, and the discharge end of the feeding ladder is located above the head end of the conveyor table.

[0008] Furthermore, an opening is provided on the side plate of the unloading ladder, and a telescopic drive stop is installed on the outer wall of the side plate of the unloading ladder. The telescopic part of the telescopic drive stop extends into the unloading ladder through the opening.

[0009] Furthermore, the support assembly includes a support column and a telescopic column, with the support column installed at the discharge end of the feeding elevator and the telescopic column installed at the feed end of the feeding elevator.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This solution is equipped with a conveyor platform, with the annealing furnace inlet located at the end of the conveyor platform. A moving component and a platform are installed on the top of the conveyor platform. The platform receives the material, and the moving component transports the platform to the annealing furnace inlet. The material is then pushed into the annealing furnace by a pushing cylinder on the platform. Compared to manually placing the material directly into the annealing furnace, this reduces labor intensity and the risk of burns due to the high temperature of the furnace.

[0011] 2. In this design, a control block and a movable plate are installed at one end of the platform near the end of the conveyor. The control block can control the movable plate to flip. When the material falls onto the platform, the movable plate flips upward, and the pushing cylinder pushes the material toward the movable plate and presses it against the movable plate, thereby fixing the material. When the material is transported to the annealing furnace inlet, the movable plate flips downward, and the pushing cylinder pushes the material directly into the annealing furnace. This design can reduce the possibility of the material getting stuck at the annealing furnace inlet due to moving around during the transportation process. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-3 As shown in the embodiment of this utility model, a feeding device for an annealing furnace includes a conveyor platform 2. The end of the conveyor platform 2 is connected to the inlet of the annealing furnace (not shown). A moving component is installed on the top of the conveyor platform 2 along the conveying direction. A platform 3 is installed on the top of the moving component. A pushing device is installed on the platform 3. The pushing part of the pushing device is arranged towards the end of the conveyor platform 2. Fixed plates 301 are installed on both sides of the platform 3. The fixed plates 301 extend away from the conveyor platform 2. A control block 304 and a movable plate 305 are provided at one end of the platform 3 near the end of the conveyor platform 2. The control block 304 is installed at the end of the platform 3. The movable plate 305 is movably connected to the control block 304 and is rotatably installed at the end of the platform 3 through the control block 304. The control block 304 has a built-in drive motor, which can drive the control block 304 to rotate.

[0018] Specifically, the pushing device includes a pushing cylinder 302 and a pushing plate 303. The pushing cylinder 302 is installed at one end of the platform 3, and the pushing part of the pushing cylinder 302 is set towards the end of the conveying platform 2. The pushing plate 303 is horizontally set on the top of the platform 3 and is connected to the telescopic part of the pushing cylinder 302. In use, material 4 is first placed between the two fixed plates 301 on the top of the platform 3. The design of the two fixed plates 301 can prevent material 4 from slipping off the sides of the platform 3. Then, the movable plate 305 is flipped upward by the built-in drive motor of the control block 304, and the pushing cylinder 302 is activated. The pushing cylinder 302 will drive the pushing plate 303 to push material 4 toward the movable plate 305 and press material 4 against the movable plate 305, thereby reducing the probability of material 4 moving and causing skewing and mess during transportation. When the moving component transports the platform 3 to the annealing furnace position at the end of the conveyor 2, the movable plate 305 is flipped downward by the built-in drive motor of the control block 304. After the movable plate 305 is no longer blocked, the pushing cylinder 302 will drive the pushing plate 303 to push material 4 into the annealing furnace feed port.

[0019] The moving assembly includes a rotary motor 201, a slide rail 202, and a lead screw 204. The slide rail 202 is mounted on the top of the conveyor table 2 and is arranged along the conveying direction. A slider is mounted on the slide rail 202, and the platform 3 is mounted on the slider. The rotary motor 201 is mounted at one end of the conveyor table 2, and a support block 203 is mounted at the other end of the conveyor table 2. One end of the lead screw 204 is connected to the rotary motor 201, and the other end is rotatably mounted on the support block 203 via a bearing. A nut (not shown) is fixedly mounted at the bottom of the platform 3, and the lead screw 204 is screwed to the nut. The forward and reverse rotation of the rotary motor 201 drives the platform 3 to move back and forth along the slide rail 202. First, the platform 3 is moved to the beginning of the conveyor table 2 to place the material 4. After placement, the platform 3 is moved to the end of the conveyor table 2. The material 4 is fed into the annealing furnace feed port by a pushing device, and then the platform 3 is moved back to the beginning of the conveyor table 2.

[0020] It should be noted that the moving device, the pushing device, and the control block 304 are all uniformly controlled by an external control system.

[0021] In one embodiment, see Figure 1 As shown, it also includes a feeding ladder 1, which is installed next to the conveyor platform 2 via a support assembly. The discharge end of the feeding ladder 1 is lower than the infeed end in terms of horizontal height, and the discharge end of the feeding ladder 1 is located above the head end of the conveyor platform 2. The material 4 can be transported to the carrier platform 3 through the feeding ladder 1.

[0022] The feeding ladder 1 has an opening on its side panel, and a telescopic drive stop 102 is installed on the outer wall of the side panel. The telescopic drive stop 102 includes a telescopic cylinder and a telescopic part. The telescopic cylinder is installed on the outer wall of the side panel of the feeding ladder 1, and the telescopic part extends into the feeding ladder 1 through the opening. The telescopic drive stop 102 can block the material 4 on the feeding ladder 1, thereby controlling the amount of material being fed. When the amount of material being fed reaches a predetermined quantity, the telescopic part will extend under the drive of the telescopic cylinder to block the material 4. When it is necessary to continue feeding, the telescopic part will retract under the drive of the telescopic cylinder to allow the feeding to continue.

[0023] In one embodiment, see Figure 1 , Figure 3 As shown, the support assembly includes a support column 103 and a telescopic column 104. The support column 103 is installed at the discharge end of the feeding ladder 1, and the telescopic column 104 is installed at the feed end of the feeding ladder 1. The tilt angle of the feeding ladder 1 can be adjusted by extending and retracting the telescopic column 104. Specifically, rotating beams 101 are installed on both sides of the feed end and both sides of the discharge end of the feeding ladder 1. The rotating beams 101 are respectively installed in conjunction with the support column 103 and the telescopic column 104. The rotating beams 101 are rotatably mounted on the support column 103 and the telescopic column 104. This design makes it more convenient to adjust the tilt angle of the feeding ladder 1 by extending and retracting the telescopic column 104.

[0024] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
