Specifically, the storage tank 1 is a rectangular parallelepiped structure with an open top, and the plug-in tube 3 is a cylindrical tubular structure. The existing nickel-chromium wire bright annealing device generally includes a plurality of wire tubes arranged at equal intervals horizontally. During annealing, the nickel-chromium wire needs to be fed into each wire tube one by one for annealing. The positioning section 301 at one end of the plug-in tube 3 is convenient for inserting into the wire tube of the annealing device before feeding, which is convenient for feeding, and can also play a role in supporting and positioning the storage tank 1.

The spacing of the limiting prisms 201 is set according to the size of the wire tube of the annealing device and the nickel-chromium wire. The placement groove corresponds to the plug-in tube 3 one by one, and the projection of the center line of the placement groove and the center axis of the plug-in tube 3 on the horizontal plane coincides. When the nickel-chromium wire is placed on the top of the support plate 2 and flattened, the limiting prisms 201 can play a role of separation, so that the nickel-chromium wire corresponds to the plug-in tube 3 one by one, and then The nickel-chromium wire is made to correspond to the wire tube of the annealing device one by one. A push plate 4 is slidably provided at the top of the support plate 2 for pushing the nickel-chromium wire at the top of the support plate 2 toward one end of the plug-in tube 3. The bottom end of the push plate 4 is provided with a plurality of grooves matching the limiting prism 201. The push plate 4 can play a guiding role when sliding along the length direction of the limiting prism 201. In this embodiment, the length of the push plate 4 is equal to the width of the inside of the storage tank 1, and the nickel-chromium wire placed inside can be pushed into the inside of the plug-in tube 3 for loading.

[0021] The support plate 2 is movably arranged inside the material storage tank 1 up and down, and the bottom end of the support plate 2 is provided with a plurality of elastic support components 6 for pushing the support plate 2 to move upward, so that the top end of the support plate 2 is higher than the top end of the plug-in tube 3, and can play the role of storing materials when no material is needed. The support plate 2 is misaligned with the plug-in tube 3 to prevent the nickel-chromium wire from slipping off the plug-in tube 3. When material is needed, the support plate 2 is pressed downward to make the top end of the support plate 2 lower than the horizontal plane of the central axis of the plug-in tube 3. At this time, the tube mouth is exposed to a large extent, so that the nickel-chromium wire placed on the top end of the support plate 2 can be accurately inserted into the plug-in tube 3;

[0022] Specifically, four elastic support components 6 are provided, which are respectively arranged at the four corners of the bottom end of the support plate 2. The elastic support component 6 includes a guide column 601 vertically fixed to the bottom end of the support plate 2 and a spring 602 sleeved on the guide column 601. The bottom end of the storage tank 1 is penetrated by a through hole for accommodating the guide column 601 to slide up and down. The bottom end of the guide column 601 extends to the outside of the storage tank 1 and is threadedly connected to a limit nut 603;

[0023] A support base 7 is fixed to the bottom end of the storage tank 1, and the bottom end of the support base 7 is lower than the bottom end of the guide column 601;

[0024] Limiting members 5 are provided at both ends of the push plate 4, and the limiting members 5 can specifically be bolts threadedly connected to the push plate 4. Sliding holes 101 for accommodating the limiting members 5 are provided on both sides of the material storage trough 1. The sliding hole 101 includes a horizontal section 1011 arranged horizontally and a vertical section 1012 connected to one end of the horizontal section 1011, and the vertical section 1012 is arranged at the end of the material storage trough 1 away from the plug-in tube 3 to form an L-shaped structure. During assembly, the push plate 4 is inserted into the interior of the material storage trough 1 from top to bottom, and the limiting members 5 on both sides pass through the sliding holes 101 and are threadedly connected to the push plate 4, which can limit the push plate 4 and prevent it from being lost. At the same time, pressing the push plate 4 can synchronously adjust the upper and lower positions of the support plate 2, which is convenient to use.

[0025] Working principle: When loading, first insert each plug-in tube 3 into the wire tube of the annealing device, then place the nickel-chromium wire on the top of the support plate 2 and flatten it, place only one nickel-chromium wire in the placement groove between two adjacent limiting prisms 201, take out the excess nickel-chromium wire, and then press the push plate 4 downward. The push plate 4 compresses the spring 602 downward through the support plate 2 until the limiting member 5 abuts against the bottom end of the vertical section 1012, and moves the push plate 4 to one side. The limiting member 5 slides inside the horizontal section 1011, and the push plate 4 pushes the nickel-chromium wire at the top of the support plate 2 into the inside of the plug-in tube 3, and then sends it into the wire tube of the annealing device to increase the loading rate. Finally, the push plate 4 is reset to carry out the next loading.
