DETAILED DESCRIPTION
[0020] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0021] like Figure 1-Figure 5As shown, the present invention provides a technical solution: a pulverizing device for producing flocculent wood fiber with anti-flying floccules, comprising a pulverizing box 1 and a pulverizing assembly 4, a feed channel 2 is fixed on the arc surface of the pulverizing box 1, and a feed hopper 3 is fixed on the top of the feed channel 2, the pulverizing assembly 4 is arranged on one side of the pulverizing box 1, and the pulverizing assembly 4 comprises an output motor 401, a hollow shaft 402, a liquid injection tube 403, a fixed outer tube 404, a telescopic piston rod 405, a rotating rod 406 and a hammer 407, the output end of the output motor 401 is connected to the hollow shaft 402, and the hollow shaft 402 is away from the output One end of the motor 401 is connected to a liquid injection tube 403 through a bearing, fixed outer tubes 404 are fixed at both ends of the surface of the hollow shaft 402, and a telescopic piston rod 405 is passed through the top of the fixed outer tube 404, a rotating rod 406 is fixed to the end of the telescopic piston rod 405, and hammer heads 407 are equidistantly sleeved on the outer wall of the rotating rod 406, the output motor 401 is fixed to the side of the crushing box 1 through a bracket, and the hollow shaft 402 is located inside the crushing box 1, the bottom of the fixed outer tube 404 is connected to the inside of the hollow shaft 402, and the inside of the hollow shaft 402 and the liquid injection tube 403 are filled with water; The specific operation is as follows: the bamboo and wood raw materials used for the production of flocculent wood fiber are cut and dried, and then pass through the feed hopper 3 along the feed channel 2 to the inside of the crushing box 1. At this time, the output motor 401 drives the hollow shaft 402 to rotate so that the hammer head 407 rotates. During the rotation of the hammer head 407, the raw materials between the hammer head 407 and the inner wall of the crushing box 1 are impacted, struck and sheared, so that the raw materials are crushed. At this time, the telescopic piston rod 405 is in a non-extended state; The space below the bottom of the telescopic piston rod 405 in the injection tube 403, the inside of the hollow shaft 402 and the fixed outer tube 404 is filled with water. By adding new water to the injection tube 403, the water volume increases, causing the water to push the telescopic piston rod 405 to extend outward, thereby reducing the distance between the end face of the rotating hammer head 407 and the inner wall of the crushing box 1. The smaller the distance, the greater the force applied to the raw material, resulting in a smaller particle size of the raw material after crushing. Therefore, the particle size of the raw material after crushing can be adjusted by injecting water to meet the needs of different particle sizes, thereby eliminating the need for secondary grinding using other crushing equipment.
[0022] like Figure 1-Figure 5 As shown, a first pulley 5 is fixed to the outer wall of the output end of the output motor 401, a second pulley 6 is penetrated through the outer wall of the end of the feed channel 2, and the second pulley 6 is meshed with the outer wall of the first pulley 5 and connected with a transmission belt 8, the end of the second pulley 6 penetrates the feed channel 2 and is connected with a push assembly 7, the push assembly 7 includes an eccentric wheel 701, a push rod 702 and a push plate 703, the side of the eccentric wheel 701 is rotatably connected to the push rod 702, and the end of the push rod 702 is rotatably connected to the push plate 703; The specific operation is as follows: the output end of the output motor 401 also drives the first pulley 5 to rotate, and the first pulley 5 drives the second pulley 6 through the transmission belt 8 to rotate the eccentric wheel 701. The rotation of the eccentric wheel 701 drives the push plate 703 to perform piston movement inside the feed channel 2 through the push rod 702. The piston movement of the push plate 703 is conducive to pushing the raw materials inside the feed channel 2 into the crushing box 1.
[0023] like Figure 1-Figure 5 As shown, the push assembly 7 also includes linked comb teeth 704, and the linked comb teeth 704 are evenly distributed inside the push plate 703, and the bottom of the linked comb teeth 704 is an arc-shaped structure. The push assembly 7 also includes a transmission fluid tank 705, an electric telescopic piston 706 and a transmission pressure head 707. The bottom of the feed channel 2 is fixed with a transmission fluid tank 705, and the top of the transmission fluid tank 705 is penetrated by an electric telescopic piston 706, and the top of the electric telescopic piston 706 is fixed with a transmission pressure head 707, the top of the transmission pressure head 707 is an arc-shaped structure, and the transmission pressure head 707 extends to the bottom of the inner wall of the feed channel 2, the bottom side of the transmission fluid tank 705 is connected to the injection pipe 403, and the transmission fluid tank 705 is connected to the hollow shaft 402 through the injection pipe 403, the bottom of the crushing box 1 is provided with a screening channel 9, and the two sides of the bottom inner wall of the crushing box 1 are provided with pressing rollers 10; The specific operation is as follows: the space below the bottom of the electric telescopic piston 706 in the transmission liquid tank 705 is filled with water, and when the push plate 703 performs piston movement in the feed channel 2, the comb teeth 704 are linked to move back and forth and push the transmission pressure head 707, so that the transmission pressure head 707 performs vertical piston movement. Each time the transmission pressure head 707 is pressed down, the electric telescopic piston 706 presses down the water, thereby replenishing new water into the injection pipe 403, thereby adjusting the distance between the end face of the hammer head 407 and the inner wall of the crushing box 1, and the distance changes from large to small and then to large, and thus circulates, thereby the raw material can be crushed into the required particle size, and at the same time, when the distance becomes larger, it is also convenient for the raw material to enter, avoiding the phenomenon of jamming or blockage caused by the inconvenience of the raw material entering due to the small distance; The electric telescopic piston 706 can adjust its length by telescoping, thereby adjusting the height of the transmission pressure head 707, thereby facilitating the control of the minimum distance between the end surface of the hammer head 407 and the inner wall of the crushing box 1, that is, facilitating the control of the minimum particle size after crushing, and the top surface of the transmission pressure head 707 and the bottom of the linkage comb teeth 704 are both arc structures, so that the transmission pressure head 707 can be pressed down during the movement of the piston of the linkage comb teeth 704, and the top surface of the transmission pressure head 707 or the bottom of the linkage comb teeth 704 can be embedded with movable balls to reduce the friction between the two when they are in contact; The powder is sieved through the sieving channel 9 and falls to the specified position on the conveyor belt during transmission, and the pressing roller 10 is pressed on the surface of the conveyor belt and rotates, thereby compacting the falling powder and then transmitting it along the conveyor belt. The powder is compacted at the first time it falls on the conveyor belt, thereby preventing it from generating flying catkins due to air flow during transmission. When the powder needs to be loosened again later, it only needs to be stirred and loosened by a mixer, and it can also cooperate with the spray head to spray atomized water for humidification, thereby further preventing the generation of flying catkins.
[0024] In summary, when the pulverizing device for producing flocculent wood fiber with anti-flying flocculent is used, first, the bamboo and wood raw materials for producing flocculent wood fiber are cut and dried, and then passed through the feed hopper 3 along the feed channel 2 to the inside of the pulverizing box 1. At this time, the output motor 401 drives the hollow shaft 402 to rotate so that the hammer head 407 rotates. During the rotation of the hammer head 407, the raw materials between the hammer head 407 and the inner wall of the pulverizing box 1 are impacted, struck and sheared, so that the raw materials can be pulverized. At this time, the telescopic piston rod 405 is in a non-extended state; The output end of the output motor 401 also drives the first pulley 5 to rotate, and the first pulley 5 drives the second pulley 6 through the transmission belt 8 to rotate the eccentric wheel 701. The rotation of the eccentric wheel 701 drives the push plate 703 to perform piston movement inside the feed channel 2 through the push rod 702. The piston movement of the push plate 703 is conducive to pushing the raw materials inside the feed channel 2 into the crushing box 1. When the push plate 703 performs piston motion inside the feed channel 2, the comb teeth 704 are linked to move back and forth and push the transmission pressure head 707, so that the transmission pressure head 707 performs vertical piston motion. Each time the transmission pressure head 707 is pressed down, the electric telescopic piston 706 presses down the water body, thereby replenishing new water body into the injection tube 403. The increase in the volume of the water body causes the water body to push the telescopic piston rod 405 to extend outward, thereby reducing the distance between the end face of the rotating hammer head 407 and the inner wall of the crushing box 1, thereby adjusting the distance between the end face of the hammer head 407 and the inner wall of the crushing box 1, and the distance changes from large to small and then to large, and thus a cycle is performed, thereby the raw material can be crushed into the required particle size, and at the same time, when the distance becomes larger, it is also convenient for the raw material to enter; The electric telescopic piston 706 can adjust its length by telescoping, thereby adjusting the height of the transmission pressure head 707, thereby conveniently controlling the minimum distance between the end surface of the hammer head 407 and the inner wall of the crushing box 1, that is, conveniently controlling the minimum particle size after crushing; Finally, the powder is sieved through the sieving channel 9 and falls to the specified position on the conveyor belt during transmission, and the pressing roller 10 is pressed on the surface of the conveyor belt and rotates, thereby compacting the falling powder and then transmitting it along the conveyor belt. The powder is compacted as soon as it falls on the conveyor belt, thereby preventing it from generating flying catkins due to air flow during transmission.
