Description

Technical Field

[0001] The utility model relates to the technical field of brick production, in particular to a preformed material layer box feeding device for sintered gangue shale bricks. Background Art

[0002] The preformed material layer box feeding device for fired bricks is a very critical part of the fired brick production process. It is mainly used to distribute the prepared raw materials with uniform thickness and density to the forming belt or template of the fired brick production line.

[0003] Chinese patent CN213382172U discloses a gangue shale sintered brick preformed material layer box feeding device, including a material layer thickness control mechanism, the material layer thickness control mechanism includes a box feeding body, a box feeding conveyor belt, a thickness control component, and a flattening component. The box feeding conveyor belt is built into the box feeding body. The flattening component is comb-shaped, and the flattening component includes a cross bar and a comb strip. The upper end of the comb strip is fixedly connected to the cross bar, and the lower end of the comb strip is freely extended to contact with the box feeding conveyor belt. The aged gangue In the process of powder material running from the input end of the box conveyor belt to the output end of the box conveyor belt, the gangue powder material first encounters the flattening component, and the gangue powder material passes between the comb bars of the gangue powder material. The gangue powder material flattened by the flattening component fills the cross section of the box body, and then encounters the thickness control component. The thickness of the gangue powder material is controlled by adjusting the height of the gate body. The gangue powder material exceeding the predetermined thickness is throttled by the gate body to ensure that the flow of the gangue powder material from the output end of the box conveyor belt is constant.

[0004] However, when conveying powder, the comb bar can only level the top of the powder. When the powder is discharged onto the conveyor belt, the powder at the bottom is subjected to greater pressure, resulting in a higher density at the bottom and a gradually decreasing density at the top. This leads to an uneven density distribution of the powder, affecting the quality of the subsequent sintered bricks. How to invent a preformed material layer box feeding device for coal gangue shale sintered bricks to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a preformed material layer box feeding device for coal gangue shale sintered bricks, aiming to improve the problem of uneven density distribution of powder in the above device, which affects the quality of the subsequent sintered brick products.

[0006] The utility model is achieved in this way:

[0007] The utility model provides a preformed material layer box feeding device for sintered gangue shale bricks, comprising a base and a flattening roller arranged on the base, side plates are fixedly connected to the outer walls of both sides of the base, both ends of the side plates are rotatably connected to conveying rollers, a conveyor belt is installed on the outer wall of the conveying roller, one end of one of the conveying rollers is fixedly connected to a first pulley, a motor is installed on the outer wall of one of the side plates, and thickness control mechanisms are installed on the inner walls of the two side plates;

[0008] The outer walls at both ends of the flattening roller are rotatably connected to the inner walls of the side plates, a plurality of comb strips are fixedly connected to the outer wall of the flattening roller, a second pulley is fixedly connected to both ends of the flattening roller, and a first belt is transmission-connected between the second pulley and the first pulley.

[0009] Preferably, the output end of the motor is fixedly connected to one end of one of the conveying rollers, and the two conveying rollers are connected in transmission via a pulley and a belt.

[0010] Preferably, the flattening roller is arranged between the side plates near the entrance of the thickness control mechanism.

[0011] By adopting the above technical solution, the conveyor belt transports the coal gangue powder while the flattening roller rotates at the same time. Before the powder passes through the thickness control mechanism to change its thickness, the rotating flattening roller drives the outer comb bar to rotate to stir the powder, thereby dispersing the powder, thereby ensuring that the density of the powder accumulation remains similar, avoiding the problem of excessive local density caused by accumulation of some powder and excessive density in other locations.

[0012] Preferably, a fixing rod is fixedly connected between the two side panels, and sliding grooves are provided on the outer walls on both sides of the fixing rod.

[0013] Preferably, two sides of the two side plates close to the fixing rod are fixedly connected with fixing frames, the outer wall of the fixing frame is fixedly connected with a limit block, and the upper side wall of the fixing frame is fixedly connected with a rack.

[0014] Preferably, the outer wall of the fixed frame is slidably connected to a fixed block, the inner wall of the fixed block is slidably connected to the outer wall of the limit block, the inner wall of the fixed block is rotatably connected to an adjusting roller, one end of the adjusting roller is fixedly connected to a gear meshing with the rack, the outer wall of the adjusting roller is fixedly connected to a sprinkling blade, the outer wall of one end of the adjusting roller is movably connected to the inner wall of the slide groove, and the fixed blocks on the two fixed frames move in opposite directions.

[0015] Preferably, a reciprocating screw connected to the inner thread of the fixed block is rotatably connected between the two side plates, one end of the reciprocating screw is fixedly connected to a third pulley, and a second belt is transmission-connected between the two third pulleys and the second pulley.

[0016] By adopting the above technical solution, in order to ensure that the conveyed powder can be evenly distributed between the side plates, the two adjusting rollers drive the outer spreading blades to continuously slide and rotate in opposite directions between the side plates, and scatter the powder accumulated in the middle position of the conveyor belt to both sides, so as to avoid insufficient powder on both sides of the conveyor belt close to the side plates when passing through the leveling component. This ensures that the powder can be evenly spread over the entire conveyor belt, thereby improving the subsequent product quality.

[0017] The beneficial effects of the utility model are:

[0018] The flattening roller rotates simultaneously when the conveyor belt is working, causing the outer comb bar to rotate to break up the surrounding powder and redistribute it to maintain consistent powder density. At the same time, the two adjusting shafts with opposite movements rotate, and the outer spreading blades stir and sprinkle the powder on the conveyor belt below back and forth, breaking up the powder accumulated in the middle of the conveyor belt to both sides, so that the powder can be evenly laid on the conveyor belt, avoiding insufficient powder on both sides of the conveyor belt near the side plate when passing through the flattening component later, thereby avoiding uneven powder density and distribution leading to inconsistent shrinkage rate of sintered bricks during the firing process, thereby ensuring uniform density, strength, hardness and shrinkage rate of subsequent sintered bricks, and improving the quality of finished bricks after sintering.

Conveyor belts 4 are installed on the outer walls of the conveyor rollers 3. One end of one of the conveyor rollers 3 is fixedly connected to a first pulley 31. A motor 5 is installed on the outer wall of one of the side plates 2. Thickness control mechanisms 6 are installed on the inner walls of the two side plates 2.

[0029] The outer walls at both ends of the flattening roller 7 are rotatably connected to the inner walls of the side plates 2, a plurality of comb strips 71 are fixedly connected to the outer wall of the flattening roller 7, a second pulley 72 is fixedly connected to both ends of the flattening roller 7, and a first belt 73 is transmission-connected between the second pulley 72 and the first pulley 31.

[0030] Furthermore; the output end of the motor 5 is fixedly connected to one end of one of the conveyor rollers 3, and the two conveyor rollers 3 are connected by a pulley with a belt for transmission, and the flattening roller 7 is arranged between the side plates 2 near the entrance position of the thickness control mechanism 6.

[0031] It should be noted that: while the motor 5 drives the conveyor belt 4 to transport the coal gangue powder, the flattening roller 7 rotates simultaneously under the action of the first pulley 31 and the second pulley 72 in cooperation with the first belt 73. Before the powder passes through the thickness control mechanism 6 to change its thickness, the rotating flattening roller 7 drives the outer comb 71 to rotate to break up the surrounding powder and redistribute it, so that the powder accumulated near the thickness control mechanism 6 maintains a consistent density, avoiding uneven density distribution and causing inconsistent shrinkage of sintered bricks during the firing process, thereby ensuring the quality of the product.

[0032] Furthermore, a fixing rod 8 is fixedly connected between the two side panels 2, and a slide groove 81 is opened on the outer walls of both sides of the fixing rod 8. The two side panels 2 are fixedly connected to the fixing frames 9 on both sides near the fixing rod 8. The outer wall of the fixing frame 9 is fixedly connected to the limit block 91, and the upper side wall of the fixing frame 9 is fixedly connected to the rack 92. The outer wall of the fixing frame 9 is slidably connected to the fixing block 10, and the inner wall of the fixing block 10 is slidably connected to the outer wall of the limit block 91. The inner wall of the fixing block 10 is rotatably connected to the adjusting roller 11, and one end of the adjusting roller 11 is fixedly connected A gear 111 is connected to the rack 92, and a sprinkling blade 112 is fixedly connected to the outer wall of the adjusting roller 11. The outer wall of one end of the adjusting roller 11 is movably connected to the inner wall of the slide 81. The fixed blocks 10 on the two fixed frames 9 move in opposite directions. A reciprocating screw rod 12 that is connected to the inner thread of the inner wall of the fixed block 10 is rotatably connected between the two side plates 2. One end of the reciprocating screw rod 12 is fixedly connected to a third pulley 121, and a second belt 13 is transmission-connected between the two third pulleys 121 and the second pulley 72.

[0033] It should be noted that: while the powder is being conveyed, the two reciprocating screws 12 rotate under the action of the second pulley 72 and the third pulley 121 in cooperation with the second belt 13, driving the fixed block 10 on the fixed frame 9 to drive the adjusting roller 11 to slide back and forth, and at the same time, the gear 111 at one end of the adjusting roller 11 and the rack 92 on the fixed frame 9 rotate simultaneously, so that the outer spreading blades 112 stir and sprinkle the powder on the conveyor belt 4 below, and scatter the powder accumulated in the middle position of the conveyor belt 4 to both sides, so that the powder can be evenly laid on the conveyor belt 4, avoiding insufficient powder on both sides of the conveyor belt 4 near the side plate 2 when passing through the flattening component later, thereby ensuring the uniformity of density, strength, hardness and shrinkage rate of subsequent sintered bricks, and improving the quality of finished bricks.

[0035] The gangue powder is continuously fed into one end of the conveyor belt 4, and the motor 5 is started at the same time to drive the conveyor belt 4 to transport the gangue powder. The powder first passes through two adjusting rollers 11 to break up the powder accumulated in the middle position of the conveyor belt 4 to both sides so that the powder can be evenly laid on the conveyor belt 4. When the scattered powder passes through the flattening roller 7, the flattening roller 7 rotates simultaneously under the action of the first pulley 31 and the second pulley 72 in cooperation with the first belt 73. The rotating flattening roller 7 drives the outer comb 71 to rotate to break up the surrounding powder and redistribute it, so that the powder accumulated near the thickness control mechanism 6 maintains a consistent density. After that, the powder passes through the thickness control mechanism 6 to change the thickness of the powder to ensure that the density and distribution position of the powder remain uniform, thereby avoiding the uneven density and distribution of the powder causing inconsistent shrinkage of the sintered bricks during the firing process, thereby ensuring the uniform density, strength, hardness and shrinkage of the subsequent sintered bricks, and improving the quality of the finished bricks after sintering.

[0036] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
