The top of the pressure plate is fixedly installed at the bottom edge of the sliding component, and the sliding component drives the pressure plate to move synchronously. The pressure plate touches the sample material downward, and its own elasticity prevents the sample from being sunken and cracked due to excessive extrusion force. The bottom of the inclined rod is hinged at the concave surface of the inner wall of the pressure plate.

The adhesion plate drives the protrusion to move synchronously, and the protrusion guides the debris through its own arc surface.

[0008] According to the above technical scheme, the anti-pollution device includes an L-shaped pull plate, a purification bag and a spray gun. The right side of the bottom of the L-shaped pull plate is fixedly installed on the left side of the outer wall of the telescopic end of the electric telescopic column. When the telescopic end of the electric telescopic column moves up and down, it drives the L-shaped pull plate to move synchronously. The top of the purification bag is fixedly installed on the bottom of the top plate, and the bottom of the purification bag is fixedly installed on the top of the left side of the L-shaped pull plate. The L-shaped pull plate pulls the purification bag to synchronously deform and reset to generate a spray force. The top of the spray gun is fixedly installed at the bottom edge of the purification bag. The purification bag sprays the purified gas through the spray gun, and the formaldehyde overflowed during material cutting is neutralized by the purified gas.

[0009] According to the above technical scheme, the anti-pollution device also includes a filter plate, an electric rotating column, an elliptical sheet and a twisting sheet. The outer wall of the filter plate is fixedly installed inside the spray gun. Through the setting of the filter plate, the external debris entering the purification capsule through the spray gun is reduced to a certain extent. The top of the electric rotating column is rotatably installed at the center of the bottom of the filter plate, and an arc groove is opened on the outer wall of the electric rotating column. When the electric rotating column is started, the electric rotating column drives the elliptical sheet to rotate, and the rotating centrifugal force causes the elliptical sheet to rotate at a horizontal angle. The back of the elliptical sheet is hinged to the outer wall surface of the electric rotating column. The elliptical sheet stirs the purified gas through its own arc surface, causing the arc surface of the elliptical sheet to cause the purified gas to be ejected in a more uniform posture. The twisting sheet is fixedly installed between the arc surface of the outer wall of the elliptical sheet and the bottom of the electric rotating column. When the elliptical sheet rotates horizontally, the twisting sheet is squeezed and deformed synchronously. When the twisting sheet is deformed, the deformed convex arc surface is used to block dirt in the external environment.

[0010] According to the above technical solution, the volatilization auxiliary device includes a connecting rod, a heating ring and a beam plate. The right side of the connecting rod is slidably installed inside the arc groove of the electric rotating column. When the electric rotating column rotates, the arc groove restricts the connecting rod, causing the connecting rod to move up and down and drive the heating ring to scrape the inner wall of the spray gun up and down. The left side of the inner wall of the heating ring is fixedly installed on the left side of the connecting rod, and the outer wall of the heating ring is slidably connected to the inner wall of the spray gun, thereby expanding the heating range of the heating ring and accelerating the volatilization of the purified gas by heating when it is ejected. The left side of the beam plate is hinged to the concave surface of the inner wall of the heating ring through a torsion spring. The heating ring drives the beam plate to move synchronously, and the beam plate swings in the opposite direction of the movement of the heating ring due to air resistance.

[0011] According to the above technical scheme, the volatilization auxiliary device also includes an L-shaped plate, a guide block, an arc-shaped sheet and a T-shaped arc-shaped plate. The bottom of the L-shaped plate is fixedly installed at the top edge of the heating ring. The heating ring drives the L-shaped plate to move up and down, and the L-shaped plate drives the guide block to move synchronously. The bottom of the guide block is fixedly installed on the top of the L-shaped plate, and the top of the guide block is located directly below the filter hole of the filter plate. The guide block stirs the filter hole of the filter plate through a conical surface to prevent the external rainy and humid activated carbon residue from clogging the filter hole of the filter plate. The bottom of the arc-shaped sheet is hinged at the inclined surface of the outer wall of the guide block through a torsion spring. The guide block drives the arc-shaped sheet to move synchronously. The arc surface of the arc-shaped sheet contacts the inner wall of the filter hole of the filter plate to generate a resistance force. At this time, the arc-shaped sheet shrinks toward the center of the guide block. The left side of the T-shaped arc plate is hinged at the inclined surface of the guide block, and the inclined surface of the T-shaped arc plate contacts the concave surface of the arc plate. When the arc plate is deformed and restored, it drives the T-shaped arc plate to slide up and down along the connection of the concave surface of the arc plate, and the connection of the arc plate is shielded by the T-shaped arc plate.

[0012] According to the above technical solution, the anti-static device includes a screw rod, a disc and a multi-rod groove ring. The bottom of the screw rod passes through and is fixedly installed on the top of the electric rotating column. The electric rotating column drives the screw rod to rotate, and the screw rod drives the disc to rotate. The bottom of the disc is fixedly installed on the top of the screw rod, and the disc drives the multi-rod groove ring to rotate. The inner side of the multi-rod groove ring is fixedly installed on the outer wall surface of the disc. The multi-rod groove ring increases the stirring range of the activated carbon inside the purification capsule through its own arc surface, thereby avoiding the aggregation and agglomeration of the activated carbon due to long-term static state.

[0013] According to the above technical scheme, the anti-stationary device also includes a power ring, a reset plate, a wave plate and a T-shaped shovel plate. The inner wall of the power ring slides and is sleeved on the outer wall surface of the screw rod. When the screw rod rotates clockwise, the spiral groove restricts the power ring, prompting the power ring to slide upward along the outer wall of the screw rod, and the power ring pulls the reset plate to deform synchronously. The reset plate is fixedly installed between the bottom of the power ring and the bottom of the inner wall of the purification capsule. When the screw rod stops rotating, the power ring is reset by the pulling force of the reset plate. The front side of the wave plate is fixedly installed on the back side of the outer wall of the power ring. When the power ring moves up and down, it drives the wave plate to move synchronously. When the wave plate moves up and down, it increases the contact area with the activated carbon through its own wave surface. The top of the T-shaped shovel plate is hinged at the bulge on the front side of the reset plate, and the bottom of the T-shaped shovel plate contacts the bottom of the inner wall of the purification capsule. During the deformation recovery process of the reset plate, the T-shaped shovel plate is driven to shovel left and right along the bottom of the inner wall of the purification capsule to prevent the activated carbon at the bottom of the purification capsule from getting damp.

The multi-rod groove ring 73 increases the stirring range of the activated carbon inside the purification capsule 52 through its own arc surface, thereby preventing the activated carbon from agglomerating and caking due to long-term standing.

[0030] The anti-stationary device 7 also includes a power ring 74, a reset sheet 75, a wave plate 76 and a T-shaped shovel plate 77. The inner wall of the power ring 74 slides and is sleeved on the outer wall surface of the screw rod 71. The reset sheet 75 is fixedly installed between the bottom of the power ring 74 and the bottom of the inner wall of the purification capsule 52. The front of the wave plate 76 is fixedly installed on the back of the outer wall of the power ring 74. The top of the T-shaped shovel plate 77 is hinged at the front protrusion of the reset sheet 75, and the bottom of the T-shaped shovel plate 77 is in contact with the bottom of the inner wall of the purification capsule 52. When the screw rod 71 rotates clockwise, the spiral groove limits the power ring 74. The power ring 74 is controlled to slide upward along the outer wall of the screw rod 71, and the power ring 74 pulls the reset plate 75 to deform synchronously. When the screw rod 71 stops rotating, the power ring 74 is reset by the pulling force of the reset plate 75. When the power ring 74 moves up and down, it drives the wave plate 76 to move synchronously. When the wave plate 76 moves up and down, it increases the contact area with the activated carbon through its own wave surface. During the process of the reset plate 75 recovering from deformation, it drives the T-shaped shovel plate 77 to shovel left and right along the bottom of the inner wall of the purification capsule 52 to prevent the activated carbon at the bottom of the purification capsule 52 from getting damp.

[0031] When in use, the electric rotating column 55 rotates through the arc groove to limit the connecting rod 61, so that the connecting rod 61 moves up and down and drives the heating ring 62 to scrape the inner wall of the spray gun 53 up and down, and at the same time expands the heating range of the heating ring 62, so that the purified gas is accelerated to volatilize by heating when it is ejected, and the purification rate is increased in the same time; the heating ring 62 drives the beam plate 63 to move synchronously, and the beam plate 63 swings in the opposite direction of the movement of the heating ring 62 due to air resistance. When the beam plate 63 swings up and down, the flow aperture of the spray gun 53 is reduced, so that the purified gas is gathered to enhance the heating effect and extend the spraying distance of the purified gas; at the same time, the heating ring 62 drives the L-shaped plate 64 to move up and down, and the L-shaped plate 64 drives the dredging block 65 to move synchronously, and the dredging block 65 stirs the filter holes of the filter plate 54 through the conical surface. Prevent the filter holes of the filter plate 54 from being blocked by the residual activated carbon due to the external rain and humidity; the drainage block 65 drives the arc piece 66 to move synchronously, and the arc surface of the arc piece 66 contacts the inner wall of the filter hole of the filter plate 54 to generate a resistance force. At this time, the arc piece 66 shrinks toward the center of the drainage block 65, and then the arc piece 66 automatically resets through the torsion spring. The arc piece 66 increases the drainage area of ​​the drainage block 65 through the arc surface, makes up for the part of the area that is difficult to be drained by the drainage block 65, and extends the service life and maintenance cycle of the filter plate 54; when the arc piece 66 is deformed and restored, it drives the T-shaped arc plate 67 to slide up and down along the concave connection of the arc piece 66, and the connection of the arc piece 66 is shielded by the T-shaped arc plate 67 to prevent the solidified dirt stirred by the drainage block 65 from adhering to the concave connection of the arc piece 66, thereby preventing the arc piece 66 from being blocked from shrinking.

[0032] The electric rotating column 55 drives the screw rod 71 to rotate, the screw rod 71 drives the disc 72 to rotate, and the disc 72 drives the multi-rod groove ring 73 to rotate. The multi-rod groove ring 73 increases the stirring range of the activated carbon inside the purification capsule 52 through its own arc surface, so as to avoid the polymerization and agglomeration of the activated carbon when it is left to stand for a long time. The opposite stirring of the multi-rod groove ring 73 promotes the dispersion of the activated carbon to ensure the individual uniformity; when the screw rod 71 rotates clockwise, the spiral groove restricts the power ring 74, so that the power ring 74 slides upward along the outer wall of the screw rod 71, and the power ring 74 pulls the reset plate 75 to deform synchronously. When the screw rod 71 stops rotating, the power ring 74 is pulled to reset by the pulling force of the reset plate 75, and the reciprocating is promoted. When the power ring 74 moves up and down, the wave plate 76 is driven to move synchronously. When the wave plate 76 moves up and down, the contact area with the activated carbon is increased through its own wave surface, the flipping rate of the wave plate 76 on the activated carbon is accelerated, the speed of the up and down alternating replacement of the activated carbon is accelerated, and the decomposition effect of the multi-rod groove ring 73 is promoted; during the deformation recovery process of the reset plate 75, the T-shaped shovel plate 77 is driven to shovel left and right along the bottom of the inner wall of the purification capsule 52. The reciprocating shoveling of the T-shaped shovel plate 77 prevents the activated carbon at the bottom of the purification capsule 52 from being damp, prevents the activated carbon from mildewing, keeps the activated carbon dynamically flipped, avoids the reduction of the purification effect of the activated carbon, and prevents the activated carbon replacement cycle from being shortened and increasing economic expenditure.
