[0036] The moving component 1 in the transmission system 1 includes a first reciprocating lead screw 106 rotatably set on the workbench 2 and arranged along the length direction of the rolling roller 6, and a threaded sleeve 1 threadedly sleeved on the first reciprocating lead screw 106, and one end of the first reciprocating lead screw 106 is fixedly sleeved with a third gear 105. The moving component 2 includes a second reciprocating lead screw 110 rotatably set on the workbench 2 and perpendicular to the length direction of the rolling roller 6, and a threaded sleeve 2 threadedly sleeved on the second reciprocating lead screw 110, the bottom of the second reciprocating lead screw 110 passes through the workbench 2 and extends to the bottom of the workbench 2, and one end of the second reciprocating lead screw 110 extending to the bottom of the workbench 2 is fixedly sleeved with a worm gear 109, and a worm 108 compatible with the worm gear 109 is rotatably set below the workbench 2.

[0037] The driving assembly includes a motor 101 arranged under the workbench 2, a transmission main shaft 102 fixedly connected to the output end of the motor 101, a first gear 103 fixedly sleeved on the end of the transmission main shaft 102 away from the motor 101, and a second gear 104 arranged on the power end of the roller 6 and meshing with the first gear 103, the second gear 104 is connected to the worm 108 through a belt 107, and the third gear 105 is meshingly connected to the second gear 104.

[0038] Reference Figure 1-3 In this embodiment, after the equipment is started, the motor 101 drives the transmission main shaft 102 to rotate, the transmission main shaft 102 drives the first gear 103 to rotate, the first gear 103 drives the second gear 104 to rotate by meshing, the second gear 104 drives the roller 6 to rotate, and the processing equipment grinds it, the second gear 104 drives the third gear 105 to rotate by meshing, the third gear 105 drives the first reciprocating screw 106 to rotate, thereby driving the blowing component to move horizontally along the axial direction of the roller body of the roller 6, the roller 6 shaft head, that is, the power end, drives the worm 108 to rotate through the belt 107, the worm 108 is meshed with the worm wheel 109, the worm wheel 109 drives the second reciprocating screw 110 to rotate, thereby driving the suction component to move in the vertical direction, the roller 6 rotates back and forth for grinding, and when grinding Rough grinding can quickly remove materials, and reverse grinding can obtain better surface roughness. Alternating the two processes can fully utilize the advantages of both, and at the same time enable the first reciprocating screw 106 and the second reciprocating screw 110 to rotate forward and backward. The first reciprocating screw 106 drives the blowing component to reciprocate along the length direction of the roller 6, and the second reciprocating screw 110 drives the suction component to move vertically along the length direction of the roller. This can not only increase the treatment coverage area of ​​dust in the air and perform dust removal more effectively, but also the cooperation between the worm 108 and the worm wheel 109 can effectively reduce the moving speed of the suction box 301. If the suction box 301 moves quickly, it will cause severe disturbance of the surrounding airflow. Such disturbance may cause the dust to be blown away by the airflow before being sucked into the suction box 301, making it difficult to effectively collect the dust.

[0039] like Figure 4 As shown, the dust removal system includes a suction component and a blowing component, the suction component includes a suction box 301 fixedly arranged on the threaded sleeve 2, a suction pipe 302 connected to the suction box 301 and a fan 303, the air inlet end of the fan 303 is connected to the air outlet end of the suction pipe 302, the air outlet end of the fan 303 is connected to two groups of branch pipes 307, the blowing component includes an outlet pipe 304 connected to the air outlet end of the filter system 4 and a blow box 306 connected to the air outlet end of the outlet pipe 304, the blow box 306 is fixedly arranged on the threaded sleeve 1; the suction box 301 sucks in the dust generated by the roller 6 during the grinding process, and guides the dust-containing gas to the filter system 4 through the suction pipe 302 and the branch pipe 307 in turn, and the dust is filtered and intercepted by the filter system 4, and the filtered airflow passes through the outlet pipe 304 and the blow box 306 in turn, and is blown to the surface of the roller 6 from the blow box 306.

[0040] like Figure 5 As shown, the air outlet pipe 304 is connected to a detection box 305, the detection box 305 is provided with an air outlet pipe 3051, the detection box 305 is provided with a dust concentration detector 5 for detecting the gas flowing out of the air outlet pipe 3051, and a small part of the airflow in the detection box 305 will flow out from the air outlet pipe 3051. When the dust concentration detector 5 detects that the dust concentration in this part of the airflow exceeds the standard, an alarm is generated to prompt the staff to increase the power of the fan 303 or detect whether the dust bag 405 in the filtration system 4 is damaged, so as to achieve a better dust prevention effect.

[0041] like Figure 6-9As shown, the filtration system 4 includes two groups of filter tank bodies 401 which are connected with the branch pipe 307 in a one-to-one correspondence. A partition is arranged in the filter tank body 401. The partition divides the inner cavity of the filter tank body 401 into a clean air chamber and a dust air chamber from top to bottom in sequence. The clean air chamber is connected with the blowing assembly. A dust removal bag 405 is fixedly installed on the partition. A skeleton for supporting the dust removal bag 405 is arranged in the dust removal bag 405. An arc-shaped spring piece 408 which arches upward is arranged at the bottom of the inner wall of the dust removal bag 405. The opening of the dust removal bag 405 is connected with the clean air chamber. A mounting pipe 409 is fixedly arranged at the center position of the top of the filter tank body 401. An enlarged end 4091 is arranged at the top of the mounting pipe 409. An exhaust pipe 402 is arranged to connect the top of the mounting pipe 409 and the dust air chamber. A connecting pipe 403 is arranged between the two groups of mounting pipes 409. An elastic pusher is arranged in the mounting pipe 409. The bottom of the elastic pusher The part passes through the top of the filter tank body 401 and extends into the dust bag 405. When the elastic force of the elastic pusher of one group of filter tank bodies 401 is less than the air pressure of the corresponding dust gas chamber, the elastic pusher moves downward under the action of the gas pressure to control the opening of the connecting pipe 403 and the impact on the arc-shaped spring piece 408. The connecting pipe 403 is opened to allow the airflow to flow from the group of filter tank bodies 401 to another group of filter tank bodies 401 for dust removal; wherein each group of branch pipes 307 is installed with a valve. When the filter tank body 401 needs to be repaired or replaced, the working filter tank body 401 can be reselected by controlling the valve on the branch pipe 307, without interfering with the normal dust removal work, thereby not reducing the dust removal efficiency. The diameter of the enlarged end 4091 is larger than the diameter of the mounting pipe 409, so that the airflow flows from the gap between the enlarged end 4091 and the limit plate 404;

[0042] A water tray 406 is fixedly installed in the clean air chamber. A plurality of through holes 4061 are opened in the water tray 406 for gas flow for heat exchange. The water tray 406 is movably connected to the elastic pushing member. The filtered gas passes through the through holes 4061 and can exchange heat with the cold water in the water tray 406. The water tray 406 is provided with a water inlet pipe for cold water to enter and a water outlet pipe for cold water to flow out (not shown in the figure), and a water pump (not shown in the figure) is provided on the water inlet pipe.

[0043] The elastic pusher includes a drive tube 407 movably connected to the installation tube 409, a limit plate 404 is fixedly installed on the top of the drive tube 407, the bottom of the drive tube 407 is located inside the dust removal bag 405, a spring 410 is wound around the surface of the drive tube 407 and a section inside the installation tube 409, a channel for liquid flow is opened in the middle of the drive tube 407, a plurality of water outlets 4072 are opened on the surface of the drive tube 407 and located inside the dust removal bag 405 to connect the channel with the inside of the dust removal bag 405, the water outlets 4072 are arranged in a row along the circumference, and a water plate 404 is opened on the surface of the drive tube 407 to connect with the water plate 404. 06, when the driving tube 407 moves downward and the water inlet 4071 enters the water tray 406, the channel is connected with the inner cavity of the water tray 406 through the water inlet 4071, and water with a certain pressure is sprayed out from the water outlet 4072 to flush the dust bag 405; when the driving tube 407 moves upward and the water inlet 4071 moves out of the water tray 406, the channel is disconnected from the inner cavity of the water tray 406, wherein a slight leakage of the water tray 406 and the driving tube 407 will not affect the overall situation, and the water at the bottom of the filter tank 401 can be supplemented.

[0044] Water is stored at the bottom of the filter tank 401, and the air outlet end of the branch pipe 307 is located below the water level. In the initial state (i.e., the filter system state 1), refer to Figure 7-8 (The direction of the arrow in the figure indicates the direction of air flow), the air flow containing dust passes through the suction box 301, the suction pipe 302, the fan 303 and the branch pipe 307 in sequence, and finally enters the filter tank 401. Some large dust particles can be mixed in the water, so that the dust is settled, and the primary filtration of the dust is achieved. The remaining dust is filtered from the dust chamber through the dust bag 405 with the air flow for secondary filtration. The filtered gas enters the clean air chamber of the filter tank 401, passes through the through hole in the water tray 406, and the filtered gas exchanges heat with the cold water in the water tray 406 to reduce the temperature of the filtered gas. Finally, it is discharged from the air outlet pipe 304 and blown to the vicinity of the roller 6 through the blowing box 306, which can further cool the roller 6 to achieve a better cooling effect.

[0045] There are two groups of filter tanks 401. The filter tanks 401 in operation, i.e., the filter tanks 401 connected to the fan 303, are the first group of filter tanks 401. The other group is the second group of filter tanks. The dust removal bags 405 of the first group of filter tanks 401 are clogged due to long-term operation or other reasons, resulting in the inability of the gas to enter the clean air chamber through the dust removal bags 405. As time goes by, the air pressure in the dust and gas chamber of the first group of filter tanks 401 increases (i.e., the second state of the filter system). Fig.10(The direction of the arrow in the figure indicates the direction of air flow) Under the action of the exhaust pipe 402, when the air pressure is greater than the elastic force of the spring 410, the air pressure pushes the drive pipe 407 downward to squeeze the spring 410 through the limit plate 404 until the connecting pipe 403 is connected with the mounting pipe 409, and the airflow in the first group of filter tank bodies 401 enters the mounting pipe in the second group of filter tank bodies 401 through the connecting pipe 403. The airflow entering the second group of filter tank bodies 401 pushes the limit plate 404 upward, stretching the spring 410, so that the limit plate 404 enters the enlarged end 4091, and the gas flows from the enlarged end 4091 through the air guide pipe 402 to the dust gas chamber of the second group of filter tank bodies 401 for filtering. At the same time, the drive pipe 407 inside the first group of filter tank bodies 401 is During the downward movement, the arc-shaped spring piece 408 will be impacted, and the dust bag 405 will be vibrated through the impact to remove the dust on the dust bag 405. At the same time, as the driving tube 407 moves downward, the water inlet 4071 and the water pan 406 are connected, and the pressurized water in the water pan 406 enters the channel opened inside the driving tube 407 through the water inlet 4071, and is sprayed out from the water outlet 4072 to clean the dust bag 405. When the air pressure in the dust and gas chamber, exhaust pipe and installation pipe of the first group of filter tank bodies drops, the driving tube 407 moves up and returns to the filtering system state one to work, which can realize automatic cleaning and effectively avoid the problem of reduced work efficiency caused by shutdown. A discharge port is provided at the bottom of the filter tank body 401 to clean the settled dust.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
