Referring to fig. 8, in a first comparative example, as another embodiment of the present invention, a counterweight 15 is disposed inside the shaking block 12; the balancing weight 15 is arranged at the center of the shaking block 12; when the shake block 12 shakes in the ball striking 8, the weight of the shake block 12 can be increased by the balancing weight 15, so that the shake block 12 can better strike the inner wall of the ball striking 8, and the vibration amplitude generated by the metal elastic sheet 13 can be larger and the duration time is longer.
The working principle is that when the filter material is used, the first nonwoven cloth layer 1 faces the air entering direction, when the air enters the inside of the material, virus and bacteria in the air can be treated through the antivirus and bacteriostasis effect of the fucoidan antibacterial layer 103, and then peculiar smell in the air is adsorbed through the activated carbon filter layer 104, macromolecular particles in the air are filtered through the fiber filter layer 105, and finally, the bacteria and the particulate matters in the air are further treated through the ceramic filter layer 106, so that the treatment effect of the air purifying device is better, meanwhile, static electricity on the surface of the material is less through the conductive filler filled in the antistatic layer 102, dust around the static electricity adsorption is effectively reduced, and the condition that the surface of the material becomes dirty is caused.
When starting the pressfitting machine and pressing the material, can make the flattening roller 6 at first with material central point put contact, and then continue the in-process of pushing down, can promote arc connecting rod 5 extrusion torsional spring, and then make the inseparable laminating of flattening roller 6 at the surface of material, roll the material flat, and then after pressfitting board 3 and material contact, accessible electric heating wire 301 melts the hot melt adhesive, paste fixedly to the material, make the material shaping, after rolling the material flat through flattening the subassembly, use electric heating wire 301 to carry out the structural design of bonding processing to the material, the function of the possibility that appears fold etc. in the material course of working has been realized reducing, the in-process of material processing has been effectually solved, receive influence such as fold easily, make the problem that the processing of material appears the flaw.
When the leveling roller 6 is in the pivoted in-process, accessible hollow vibration post 7 drives and strikes ball 8 and remove, will strike ball 8 and drive the mid-air back, strike ball 8 and can fall down after rising to a certain extent, and then smash the bottom position of vibrating post 7 in the hollow to can make leveling roller 6 produce and vibrate, after leveling roller 6 contacts with the material, can extrude the air between the material through vibrating, make remaining air between the material less, thereby can effectually reduce remaining air too much between the material, lead to the bulge between the material, the possibility that leads to the fact the influence to the processing of material easily.
When the hollow vibration column 7 lifts the striking ball 8, the iron sheet layer 10 is adsorbed by the magnetic stripe 9, so that the height of the hollow vibration column 7 lifted the striking ball 8 is higher, the striking ball 8 falls down and is larger in striking force, the vibration strength of the flattening roller 6 is higher, and the air extruding effect is better.
When the hollow oscillation column 7 generates oscillation, the oscillation rod 11 can absorb the oscillation generated by the hollow oscillation column 7 and further continuously oscillate, and in the oscillation process of the oscillation rod 11, the oscillation can be continuously conducted to the outside of the flattening roller 6, so that the oscillation of the surface of the flattening roller 6 is stable, and the duration is longer.
When the bottom of knocking ball 8 and knocking hollow shock post 7 produces and vibrate, can make shake piece 12 and shake in the inside of knocking ball 8, and then pound the inside wall of knocking ball 8 to can make the inside of knocking ball 8 continuously produce and vibrate, when the piece 12 returns slowly simultaneously, metal elastic piece 13 also can rock a period, thereby can make the knocking ball 8 continue to produce and vibrate, make the vibration effect on the roll-off 6 surface better.
When the striking ball 8 strikes the surface of the hollow oscillating column 7, the reinforced protection outer layer 14 can protect the surface of the iron sheet layer 10, and the conditions that the surface of the iron sheet layer 10 is scratched and worn are effectively prevented.
