[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0027] Example 1

[0028] Figure 1-4 What is shown is a structural schematic diagram of a specific embodiment of the utility model.

[0029] A blanking buffer device for a quenched and tempered mesh belt comprises a blanking pipe 1 having a passage 2 passing through both ends thereof, a plurality of mounting openings 7 being provided on the side wall of the blanking pipe 1, and a buffer assembly 8 being provided at the mounting openings 7;

[0030] The buffer assembly 8 includes a support plate 9 detachably connected to the mounting opening 7 ; the support plate 9 extends into the interior of the channel 2 and is provided with a telescopic buffer plate 11 , with a spring 18 provided between the buffer plate 11 and the support plate 9 .

[0031] Among them, the entire buffer assembly 8 can be quickly replaced at the installation port 7 through the detachable buffer plate 11. Through the setting of the buffer plate 11 and the spring 18, the material falls on the buffer plate 11 and cooperates with the spring 18 to achieve buffering, avoiding the entire buffer assembly 8 from being easily damaged. Compared with the existing technology, it is not only easy to replace but also can reduce the damage to the entire assembly.

[0032] In this embodiment, the buffer plate 11 includes an L-shaped buckle plate 12; one inner corner side of the buckle plate 12 remains parallel to the outer side of the blanking tube 1, and the other side is in contact with the bottom of the mounting port 7; one side of the buckle plate 12 is provided with an extension plate 15 that extends into the channel 2 and is in an inclined state; one side of the extension plate 15 is provided with a stop block 14 that is pressed against the inner wall of the blanking tube 1; the side of the buckle plate 12 that is parallel to the blanking tube 1 is provided with a threaded bolt 13; the end of the bolt 13 is pressed against the outer side of the blanking tube 1, and cooperates with the stop block 14 to clamp the wall of the blanking tube 1.

[0033] Among them, by the arrangement of the stop block 14 pressing against the inside of the drop tube 1 and the bolt 13 pressing against the outer wall of the drop tube 1, the entire buffer assembly 8 only needs to extend the extension plate 15 and the buffer plate 11 from the installation opening 7. When the stop block 14 and the buckle plate 12 are respectively located inside and outside the drop tube 1, the entire buffer assembly 8 can be installed by tightening the bolt 13. When disassembling, only the bolt 13 needs to be turned to take out the entire assembly. Compared with the existing technology, it is very easy to install and replace.

[0034] In this embodiment, one side of the buffer plate 11 is provided with a plurality of telescopic rods 16 that pass through the extension plate 15; one end of the telescopic rod 16 that passes through the extension plate 15 is threadedly engaged with a nut 17; and a spring 18 is sleeved on a section of the telescopic rod 16 located between the buffer plate 11 and the extension plate 15.

[0035] The arrangement of the telescopic rod 16 enables telescopic cooperation between the buffer plate 11 and the support plate 9 , so that the spring 18 can cooperate with the buffer plate 11 to achieve buffering.

[0036] In this embodiment, a baffle 10 is provided on one side of the buffer plate 11 , and the baffle 10 is used to seal the installation opening 7 .

[0037] Among them, through the setting of the baffle 10, after the entire buffer assembly 8 is installed, the baffle 10 can block the excess part of the installation port 7 to prevent the internal rolling blanks from leaking out of the installation port 7, such as smaller objects such as bearings.

[0038] In this embodiment, the drop tube 1 is rectangular; the plurality of mounting openings 7 are arranged at intervals on the side wall of the drop tube 1 and distributed on opposite sides of the drop tube 1 .

[0039] Among them, by setting up a plurality of installation openings 7 at intervals and distributing them on both sides of the drop tube 1, when the drop tube 1 is in a vertical state, the material can be buffered by the buffer components 8 of different heights after falling from the upper end, and the distribution on both sides can prevent the material from falling directly from the top to the bottom. For details, see Figure 3 The axis of the channel 2 is blocked by several buffer components 8 of different heights and relatively arranged. The material will fall from the top of the channel 2. After being buffered by several buffer components 8, the material will continuously change its falling trajectory, thereby being buffered.

[0040] In this embodiment, a base 3 is provided at one end of the channel 2, and connecting plates 4 are provided on both sides of the blanking tube 1; a guide rod 5 and an adjusting screw 6 are provided at the base 3 along the length direction of the blanking tube 1; the guide rod 5 is provided through the connecting plate 4, and the adjusting screw 6 is threadedly engaged with the connecting plate 4.

[0041] Among them, through the arrangement of the guide rod 5 and the adjusting screw 6, the height of the blanking tube 1 can be adjusted after rotating the adjusting screw 6, so that the top end of the blanking tube 1 can cooperate with the discharge port of the mesh belt furnace for blanking.

[0042] Working principle: The top of the drop tube 1 is matched with the discharge port of the mesh belt furnace. After the material is discharged from the mesh belt furnace, it enters the top of the drop tube 1 and enters the channel 2. The material will fall inside the channel 2. When falling, it will be blocked and buffered by several buffer components 8. At the same time, the falling trajectory will be continuously changed to further buffer; during buffering, the material will hit the buffer plate 11, and the buffer plate 11 will move toward the surface of the extension plate 15 and compress the spring 18, and buffering is achieved by the spring 18; during installation, only the buffer plate 11 and the extension plate 15 need to be partially extended into the channel 2 from the installation port 7. When the stop block 14 and the buckle plate 12 are respectively located on the inner and outer sides of the drop tube 1, the bolt 13 is tightened to the outside of the drop tube 1. At this time, the stop block 14 will be pressed against the inner wall of the drop tube 1, and the stop block 14 and the bolt 13 will cooperate to install the buffer component 8; when disassembling, only the bolt 13 needs to be turned, and the buffer component 8 can be taken out from the installation port 7 for replacement.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
