Description

Technical Field

[0001] This utility model relates to the technical field of magnetic material feeding, and in particular to a feeding device for a heat treatment annealing furnace. Background Technology

[0002] The annealing furnace for heat treatment of magnetic materials uses a fan to circulate air and ensure a uniform temperature distribution within the furnace chamber, thereby achieving the annealing treatment of magnetic materials. Currently, to improve work efficiency, material feeding is generally done using transport vehicles, robotic arms, or transport lines. However, magnetic materials come in various styles, and transport lines are more suitable for feeding diverse materials. But on current transport lines, the direction is difficult to control, and the height on both sides is not high enough, which poses a danger if hot magnetic materials fly out.

[0003] A method for feeding steel billets into an annealing furnace, disclosed in Chinese Patent Publication No. CN114807564A on July 29, 2022, includes the following steps: S1, a transport roller is used to transport the steel billet, and a feeding device is provided at the unloading end of the transport roller; S2, the feeding device evenly distributes the steel billet, and an angle adjustment mechanism is provided at the bottom of the feeding device; S3, the angle adjustment mechanism flips the feeding device, and the steel billet automatically slides from the feeding device into the annealing furnace; S4, the feed gate of the annealing furnace descends, the annealing furnace operates, and the steel billet is annealed. After the steel billet is rolled, the transport roller and feeding device automatically feed the billet into the annealing furnace without manual assistance, reducing the probability of safety accidents. The angle adjustment mechanism at the bottom of the feeding device allows for flipping of the feeding device. The drawback of this invention is that it cannot adjust the transport direction and cannot effectively block the material. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of existing technologies that cannot adjust the transport direction and cannot better block materials, and provides a feeding device for a heat treatment annealing furnace that can adjust the transport direction and better block materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A feeding device for a heat treatment annealing furnace includes: several supports, which are evenly divided into two groups and placed on the left and right sides respectively, with the supports in one group being evenly distributed front and back. Two baffles are placed on the upper surfaces of the two sets of brackets, and the lower surfaces of the baffles are fixedly connected to the upper surfaces of the brackets. Several conveying rollers are evenly distributed between two baffles, and the two ends of the conveying roller shafts are respectively placed inside the baffles on both sides and rotatably connected to the baffles; Several rotating motors are placed on the outside of a side baffle, and the rotating shafts of the rotating motors are fixedly connected to one end of the conveying roller shaft. Several guide plates are divided into two groups and evenly distributed on the inner sides of two baffles. The guide plates are placed above the conveying rollers. The inner side of the guide plate, which is parallel to the distribution direction of the conveying rollers, has an arc-shaped cross-section. The arc-shaped end of the guide plate near the starting point of the conveying is tangent to the inner side of the baffle. The guide plate is fixedly connected to the baffle.

[0006] In use, first move the support to connect the tail end of the feeding device with the inlet end of the annealing furnace, then turn on the rotating motor to let the magnetic material be carried by the rotation of the conveying roller. Even if it deviates from the direction, it will be blocked by the guide plate and guided to run towards the middle of the conveying roller. The baffle will effectively prevent the magnetic material from falling, thus achieving the purpose of adjusting the transport direction and better blocking the material.

[0007] Preferably, a base plate is provided below the conveying roller, and a slot is provided on the inner side of the baffle. The two ends of the base plate are respectively placed in the slots on the two baffles and are engaged with the baffles through the slots. The base plate can catch some debris, and the slots allow the base plate to be disassembled and installed for easy cleaning.

[0008] Preferably, a connecting plate is provided between the two baffles. The connecting plate is positioned behind the rearmost conveying roller, and its two ends are fixedly connected to the inner surfaces of the two baffles respectively. The height of the connecting plate is lower than the upper surface of the conveying roller. Several dividing strips are evenly distributed on the upper surface of the connecting plate. The dividing strips are perpendicular to the conveying roller, and their upper surfaces are higher than the upper surface of the conveying roller. The lower surfaces of the dividing strips are fixedly connected to the upper surface of the connecting plate. The connecting plate facilitates connection to the operating belt of the annealing furnace, and the dividing strips can divert magnetic materials, preventing them from accumulating in the annealing furnace.

[0009] Preferably, the inner side of the guide plate, perpendicular to the distribution direction of the conveying rollers, has an arc-shaped cross-section, and the guide plate is wider at the top and narrower at the bottom. The shape of the guide plate prevents magnetic material that hits it from flying off the conveying path.

[0010] Preferably, there are several conveying rollers between adjacent rotating motors, and the number of spaced conveying rollers is the same. Placing the rotating motors at intervals can reduce energy waste and also reduce the impact of different rotating speeds of the rotating motors.

[0011] Preferably, the outer surface of the conveying roller has a plurality of protrusions evenly distributed thereon. The cross-sectional shape of the protrusions is semi-circular, and the protrusions are fixedly connected to the outer surface of the conveying roller. The protrusions can reduce the contact between the high-temperature magnetic material and the conveying roller, preventing damage to the conveying roller from high temperature, and the protrusions can increase friction to make the transport of magnetic materials smoother.

[0012] The beneficial effects of this utility model are: it can adjust the transport direction and better block materials; the base plate can catch some debris, and the slot allows the base plate to be disassembled and installed for easy cleaning; the connecting plate facilitates connection to the annealing furnace's operating belt, and the dividing strip can divert magnetic materials and prevent them from accumulating in the annealing furnace; the shape of the guide plate can prevent magnetic materials that collide with the guide plate from flying off the transport path; the spaced placement of the rotating motors can reduce energy waste and also reduce the impact of different rotating speeds of the motors; the protrusions can reduce the contact between high-temperature magnetic materials and the conveying rollers, preventing damage to the conveying rollers from high temperatures, and the protrusions can increase friction to make the transport of magnetic materials smoother.

[0018] like Figure 1 and Figure 2 As shown, there is a connecting plate 8 between the two baffles 5 and the connecting plate 8 is placed behind the last conveying roller 2. The two ends of the connecting plate 8 are fixedly connected to the inner sides of the two baffles 5 respectively. The height of the connecting plate 8 is lower than the upper end face of the conveying roller 2. Several dividing strips 9 are evenly distributed on the upper end face of the connecting plate 8. The dividing strips 9 are perpendicular to the conveying roller 2. The upper end face of the dividing strips 9 is higher than the upper end face of the conveying roller 2. The lower end face of the dividing strips 9 is fixedly connected to the upper end face of the connecting plate 8.

Then turn on the rotating motor 3 to let the magnetic material be carried by the rotation of the conveying roller 2.

Even if it deviates from the direction, it will be blocked by the guide plate 4 and guided to run towards the middle of the conveying roller 2. The baffle 5 will effectively prevent the magnetic material from falling.
