Accompanying drawing explanation
Fig. 1 is the side direction view of the apparatus for leveling extruded for degradation plastic foam sheet.
Fig. 2 is the forward view of the apparatus for leveling extruded for degradation plastic foam sheet.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
The utility model is different from the mode that traditional roller prolongs crowded line pressure, but adopts leveling to be with 16 clamping move modes parallel with 17 to replace traditional roll extrusion.
The apparatus for leveling that the utility model is extruded for the micro-foam sheet of degradation material as depicted in figs. 1 and 2, is provided with drive part, flattening partially and running part in frame 18; Wherein, drive part is that miniature cycloidal planetary gear speed reducer 14, flattening partially are that upper and lower leveling is with 16 and 17, and running part is chain or Timing Belt 15;
Adopt upper and lower leveling to be with 16 and 17, by the planar movement of upper driven roller 1 and driven voller 5 and lower driven roller 2 and the micro-foam sheet of driven voller 6 drive formation, reach identical translational speed by chain or Timing Belt 15.
Described upper and lower leveling is with 16 and 17 respectively on upper driven roller 1 and driven voller 5 and lower driven roller 2 and driven voller 6.Upper and lower drive roll 1 and 2 one sides are sprocket wheel or synchronous pulley 3 and 4 for dress, and formed objects.Sprocket wheel or synchronous pulley 8 are housed on reductor 14 equally.By chain or Timing Belt 15, reductor 14 drives upper and lower drive roll 1,2 rotation, thereby drives leveling to be with 16 and 17 to move with identical speed.By control the speed of reductor 14 adjust leveling be with 16 and 17 and extrusion sheet synchronous, reach the effect of leveling formed sheet upper and lower surface sizing.
Can make chain drive-belt or Timing Belt 15 produce degree of tightness variation owing to adjusting upper and lower drive roll 1,2 distance, therefore the utility model has designed expansion tightening wheel 7 and has automatically adjusted degree of tightness variation.
For the ease of heat conduction, upper and lower leveling adopts metal material or processes lower than the nonmetal heatproof material of 1mm thickness with 16 and 17, and bandwidth is determined according to extrusion sheet size.
Described upper and lower drive roll 1,2 is with interior circulatory mediator passage, and two ends are with swivel joint 11,12.Can the water of temperature required constant temperature or wet goods medium be injected by swivel joint 11,12 by external temperature control device, control the temperature of upper and lower drive roll 1,2, be with on 16,17 thereby heat is conducted to leveling up and down, meet technique needs.
Upper driven roller 1 and driven voller 5 both sides all can be carried out upper and lower distance by turbine and worm elevator 9 and 10 with plain bearing housing and be adjusted.Described upper driven roller 1 and driven voller 5 connect by sliding connecting device and left and right turbine and worm elevator 9,10 respectively.By rotation hand wheel 13, left turbine and worm elevator 9 liftings can be adjusted distance between upper and lower drive roll 1 and 2.Also can be used for adjusting the distance between upper and lower driven voller 5 and 6 by adjusting right turbine and worm elevator 10 as a same reason.
Use procedure of the present utility model is as follows: first adjust turbine and worm elevator 9 and 10, leveling is up and down adjusted to the distance needing with the distance between 16 and 17.Pass into medium circulation and temperature is controlled to setting value by swivel joint 11 and 12.Start reductor 14, drive upper and lower driven roller 1 and 2 incorgruous rotations by chain drive-belt or Timing Belt 15, drive leveling to be up and down with 16 and 17 to rotate.When sheet material is flattened up and down and is with 16 and 17 rotations to bring into from die head is extruded, by flattening up and down the surfaces extruding smooth with 16 and 17 and preventing surperficial premature hardening with uniform temperature, simultaneously due to leveling be up and down with 16 and 17 and sheet material synchronization move a period of time, make large leap ahead of time of sizing, thereby the sheet material after making out just has smooth surface quality.
Technique scheme is a kind of embodiment of the present utility model, for those skilled in the art, on the basis that the utility model discloses principle, be easy to make various types of improvement or distortion, and be not limited only to the described structure of the above-mentioned specific embodiment of the utility model, therefore previously described just preferred, and do not there is restrictive meaning.
