It is mainly composed of a heating furnace, an oil tank, a cleaning machine, a tempering furnace and other main parts. Materials (metal parts) are conveyed by a mesh belt during processing in each part.

[0025] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] To solve the technical problems in the prior art, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0027] Such as Figures 1 to 6As shown in the figure, an embodiment of the utility model discloses a belt - type furnace blanking buffer device, which includes an aggregate cover 1 and a buffer baffle 2. The aggregate cover 1 is arranged above the mesh belt 5, and at least two - stage buffer baffles 2 are arranged inside the aggregate cover 1. The buffer surface of the buffer baffle 2 faces the blanking direction. Adjacent buffer baffles 2 are arranged in a staggered up - and - down manner. A rotating shaft 3 and a first fixing member 4 are installed inside the aggregate cover 1. The first fixing member 4 is rotatably assembled on the rotating shaft 3, and the buffer baffle 2 is detachably installed on the first fixing member 4. The first fixing member 4 is fixedly connected to the side wall of the aggregate cover 1.

[0028] Among them, the aggregate cover 1 is a semi - enclosed structure. An inlet 101 is arranged above the aggregate cover 1. The blanking port of the lifting mechanism of the belt - type furnace cleaning machine 6 is arranged with the aggregate cover 1, that is, the inlet 101 of the aggregate cover 1 is communicated with the blanking port. An outlet 102 is arranged below the aggregate cover 1, and a mesh belt 5 for receiving materials is arranged below the outlet 102. The mesh belt 5 is arranged on the belt - type furnace, and a backing plate is arranged below the mesh belt 5. After being cleaned by the cleaning machine 6, the materials are lifted by the lifting mechanism of the cleaning machine 6 and then transferred, and fall back above the mesh belt 5 of the furnace 7 through the aggregate cover 1. Among them, the buffer device in this embodiment reduces the falling speed of the materials, reduces the collision of the materials on the mesh belt 5, and then the materials enter the furnace for tempering processing.

[0029] In this embodiment, a rotating shaft 3 is installed inside the aggregate cover 1, and the buffer baffle 2 is installed inside the aggregate cover 1 through the rotating shaft 3 and the first fixing member 4, so that the buffer surface of the buffer baffle 2 faces the blanking direction of the materials. At least two - stage buffer baffles 2 are arranged in a staggered up - and - down manner, slowing down the materials falling from the inlet 101 above the aggregate cover 1 layer by layer, and finally falling on the mesh belt 5. Through this buffer device, the collision between the materials with heavier mass and sharp - angled shapes and the mesh belt 5 is reduced, avoiding the situation that the mesh belt 5 is damaged by being hit and has holes, breaks, etc., resulting in the shutdown and maintenance of the equipment due to first - level faults, and avoiding the situation of poor collision scars on the materials.

[0030] The end of the rotating shaft 3 is provided with threads, and the rotating shaft 3 is fixed on the aggregate cover 1 through nuts.

[0031] In some embodiments, the buffer baffle 2 is a rubber plate or a plastic plate.

[0032] The blanking direction refers to the direction in which the materials fall / drop. The buffer surface of the buffer baffle 2 arranged on the top layer faces the material falling direction of the blanking port of the cleaning machine 6, and the buffer surface of the buffer edge arranged on the lower layer faces the dropping direction of the materials passing through the buffer surface of the upper - layer buffer baffle 2. In any case, it is only necessary to ensure that the buffer surface of each layer of buffer baffle 2 will catch the materials dropped from above, and the materials on the upper - layer buffer baffle 2 fall onto the lower - layer buffer baffle 2, and the materials fall onto the mesh belt 5 through the buffer surface of the lowermost - layer buffer baffle 2.

[0033] In some embodiments, an elastic force adjusting mechanism 8 is further provided. The elastic force adjusting mechanism 8 includes a second fixing member 81 and an elastic member 82. The second fixing member 81 is rotatably connected to the rotating shaft 3. An elastic member 82 is assembled between the first fixing member 4 and the second fixing member 81. The first fixing member 4 is connected to the side wall of the aggregate cover 1 through the second fixing member 81. The direction of elastic deformation of the elastic member 82 is parallel to the central axis of the rotating shaft 3, and the relative distance between the elastic member 82 and the rotating shaft 3 is adjustable.

[0034] The additional elastic force adjusting mechanism 8 freely adjusts the rotational elastic force of the first fixing member 4 to adapt to the falling speeds and collision impacts of materials with different masses and various shapes and sizes. Specifically, an elastic member 82 is installed between the first fixing member 4 and the second fixing member 81. The second fixing member 81 is fixedly connected to the side wall of the aggregate cover 1 to ensure that the direction of elastic deformation of the elastic member 82 is parallel to the central axis of the rotating shaft 3. Both the first fixing member 4 and the second fixing member 81 can rotate freely. The elastic force of the first fixing member 4 is adjusted by adjusting the relative position between the elastic member 82 and the rotating shaft 3, that is, by adjusting the elastic member 82 to be away from or close to the rotating shaft 3, thereby realizing the adjustment of the rotational elastic force of the first fixing member 4.

[0035] The second fixing member 81 is connected to the side wall of the aggregate cover 1. In this way, the first fixing member 4 is fixedly connected to the aggregate cover 1 through the second fixing member 81. Usually, second fixing members 81 are respectively provided at both ends of the first fixing member 4. Similarly, elastic force adjusting mechanisms 8 are respectively connected to both ends of the first fixing member 4.

[0036] Furthermore, the ways to adjust the relative distance between the elastic member 82 and the rotating shaft 3 are as follows: a first sliding rail 83 is provided on the first fixing member 4, a second sliding rail 84 is provided on the second fixing member 81, a first connecting block 85 is provided at one end of the elastic member 82, a second connecting block 86 is provided at the other end of the elastic member 82. The first connecting block 85 is slidably assembled on the first sliding rail 83, the second connecting block 86 is slidably assembled on the second sliding rail 84, and fixing blocks 87 are respectively connected to the first connecting block 85 and the second connecting block 86.

[0037] After adjusting the relative distance between the elastic member 82 and the rotating shaft 3 by sliding the first connecting block 85 on the first sliding rail 83 and the second connecting block 86 on the second sliding rail 84, the first connecting block 85 is connected and fixed to the first fixing member 4 through the fixing block 87, and the second connecting block 86 is connected and fixed to the second fixing member 81 through the fixing block 87 to lock the position of the elastic member 82, thereby realizing the rotational elastic force of the first fixing member 4 and the buffer baffle 2 thereon.

[0038] The first sliding rail 83 can be a long slot or a long hole opened on the first fixing member 4, and the second sliding rail 84 can be a long slot or a long hole opened on the second fixing member 81.

[0039] Preferably, the elastic member 82 is a spring. One end of the spring is fixedly connected to the first connecting block 85, and the other end of the spring is fixedly connected to the second connecting block 86.

[0040] The connection between the first connecting block 85 and the fixed block 87 can adopt a bolt-nut connection method. Correspondingly, the connection between the second connecting block 86 and the fixed block 87 can also adopt a bolt-nut connection method. By loosening or tightening the nut to separate the fixed block 87 and moving the first connecting block 85 and the second connecting block 86, the relative position between the elastic member 82 and the rotating shaft 3 can be adjusted.

[0041] In some embodiments, an arc-shaped groove 9 is formed on the side wall of the aggregate cover 1 close to the end of the rotating shaft 3. The radian direction of the arc-shaped groove 9 is the same as the circumferential direction of the rotating shaft 3. A positioning member 10 is provided on the second fixing member 81, and the positioning member 10 is fixedly arranged in the arc-shaped groove 9.

[0042] The arc-shaped groove 9 is designed on the aggregate cover 1. By sliding the positioning member 10 on the second fixing member 81 in the arc-shaped groove 9, the angle of the second fixing member 81 is adjusted. The first fixing member 4 is connected to the second fixing member 81 through the elastic force adjusting mechanism 8. When the angle of the second fixing member 81 is adjusted, the angles of the first fixing member 4 and the buffer baffle 2 thereon are also adjusted accordingly.

[0043] Furthermore, the radian direction of the arc-shaped groove 9 is designed along the circumferential direction of the rotating shaft 3. When the positioning member 10 slides on the arc-shaped groove 9, the first fixing member 4 and the second fixing member 81 can rotate freely, that is, the first fixing member 4 and the second fixing member 81 are respectively rotatably connected to the rotating shaft 3. The first fixing member 4 and the second fixing member 81 can easily rotate around the rotating shaft 3 to achieve adjustment of different angles, so as to adapt to the buffer of materials with different masses and various shapes during blanking, and prevent phenomena such as material accumulation and jamming.

[0044] The side wall of the aggregate cover 1 close to the end of the rotating shaft 3 is provided with an arc-shaped groove 9, that is, arc-shaped grooves 9 are provided on both sides of the aggregate cover 1. Correspondingly, positioning members 10 are connected to both ends of the second fixing member 81.

[0045] When the angles of the first fixing member 4 and the second fixing member 81 are adjusted in place, the angle is fixed by locking the positioning member 10. Preferably, the positioning member 10 is a threaded screw rod, and the screw rod is welded to the second fixing member 81. The positioning member 10 passes through the arc-shaped groove 9, and the connection between the screw rod and the aggregate cover 1 is fixed by tightening the nut, so as to realize the angle fixation of the first fixing member 4, the buffer baffle 2 and the second fixing member 81.

[0046] In a specific example, angle graduation lines are provided at the arc-shaped groove 9. The angle graduation lines can be engraved to realize angle quantization, which is convenient for quickly and accurately adjusting the angles of the first fixing member 4, the second fixing member 81 and the buffer baffle 2.

[0047] In some embodiments, mounting grooves 41 are respectively provided on both sides of the first fixing member 4, and the buffer baffle 2 is inserted through the mounting grooves 41. The two sides of the buffer baffle 2 that protrude out of the mounting grooves 41 respectively extend towards the material discharging direction and abut against the side walls of the aggregate cover 1.

[0048] Through the mounting grooves 41, the buffer baffle 2 can be simply and quickly installed and replaced. At the same time, the two sides of the buffer baffle 2 that protrude out of the mounting grooves 41 extend to the side walls of the aggregate cover 1, and the two sides of the buffer baffle 2 extend in the material discharging direction. In this way, the elastic force adjusting structure between the first fixing member 4 and the second fixing member 81 is blocked by the two sides of the buffer baffle 2, and the material will not fall onto the elastic force adjusting mechanism 8, and the material is completely in contact with the buffer baffle 2.

[0049] In a specific example, a locking block 11 is embedded in the mounting groove 41, and the locking block 11 is fixedly connected to the first fixing member 4. By embedding the locking block 11 in the mounting groove 41, the buffer baffle 2 is tightly clamped with the mounting groove 41. At the same time, the locking block 11 is designed to be fixedly connected to the first fixing member 4. Preferably, the locking block 11 is fixed by a locking bolt 12, which further ensures the connection reliability between the buffer baffle 2 and the mounting groove 41 of the first fixing member 4.

[0050] Furthermore, a support member 42 is provided in the middle of the first fixing member 4, and the support member 42 abuts against the lower surface of the buffer baffle 2. This can prevent the buffer baffle 2 from being severely deformed due to excessive impact when too heavy or a large amount of material falls on the buffer baffle 2.

[0051] In a specific example, a hinge portion is provided on the first fixing member 4, and the hinge portion is sleeved on the outer periphery of the rotating shaft 3. The first fixing member 4 and the rotating shaft 3 are connected by a hinge connection method, so that the first fixing member 4 can rotate freely. Preferably, the second fixing member 81 and the rotating shaft 3 also adopt the same hinge connection as that between the first fixing member 4 and the rotating shaft 3.

[0052] In a specific example, at least two - stage buffer baffles 2 are provided, including a primary buffer baffle 2 and a secondary buffer baffle 2. The buffer surface of the secondary buffer baffle 2 faces the material discharging direction of the material on the primary buffer baffle 2, and the material falls onto the mesh belt 5 from the buffer surface of the secondary buffer baffle 2.

[0053] Two - stage buffer baffles 2 are designed, namely a primary buffer baffle 2 and a secondary buffer baffle 2. The primary buffer baffle 2 and the secondary buffer baffle 2 are respectively fixed by the rotating shaft 3. The primary buffer baffle 2 and the secondary buffer baffle 2 are inclined, but the buffer surfaces of the primary buffer baffle 2 and the secondary buffer baffle 2 always face the material discharging direction, and this material discharging direction is the direction in which the material falls.

[0054] The main functions of the present utility model: A buffer device is added inside the aggregate cover 1 to prevent the heavy and sharp-cornered materials from directly falling and damaging the mesh belt 5, protect the mesh belt 5 of the conveyor belt furnace, reduce the risk of furnace shutdown for maintenance due to the breakage and holes of the mesh belt 5 in the conveyor belt furnace, improve the use efficiency of the equipment, and reduce the equipment maintenance cost.

[0055] The buffer device is also provided with angle adjustment and elastic force adjustment. When using the rubber or plastic buffer baffle 2, it can be applicable to materials of various shapes and sizes. When the material shape is large, the slope of the baffle can be slowed down; when the material shape is small, the slope of the baffle can be increased, so that the materials will not accumulate during production, and it has the advantages of being applicable to various materials and convenient to use.

[0056] In summary, after reading the documents of the present utility model, those of ordinary skill in the art can make various other corresponding transformation schemes without creative mental labor according to the technical solutions and technical concepts of the present utility model, and all of them fall within the scope protected by the present utility model.
