Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1 to 5, the inner roller 5 and the outer roller 6 are both hollow structures, both ends of the inner roller 5 and the outer roller 6 can be communicated, and the outer surface of the inner roller 5 is attached to the inner surface of the outer roller 6. The inner roller 5 and the outer roller 6 are made of metal materials with good heat conductivity, such as metal materials or alloys of copper, aluminum and the like.

The first conveying assembly 12 and the second conveying assembly 13 are both belt conveying assemblies, the first conveying assembly 12 is located below the outer roller 6, and the second conveying assembly 13 is located above the outer roller 6.

A plurality of first flutings 8 have been seted up to equidistant axial on the interior roller 5, and a plurality of second flutings 9 have been seted up to equidistant axial on the outer roller 6, and length between the second fluting 9 is greater than the width of first fluting 8.

At least one fixed sleeve 3 is fixedly connected with the side port of the inner roller 5, the outer roller 6 is connected with the fixed sleeve 3 in a sliding mode, the fixed sleeve 3 is fixedly connected with a support 2 pointing to the axis of the inner roller 5, the support 2 is connected with a shaft sleeve, and the shaft sleeve is connected with an output shaft key of a speed reduction motor.

The gear motor can be installed on the ground and other places through an independent fixing frame, so that the inner roller 5 and the outer roller 6 can be driven to rotate continuously.

It is worth mentioning that the support 2 is for setting up in the both sides of interior roller 5 and outer roller 6 in pairs, and the support 6 area should increase to can play and carry out confined effect to the side, make atmospheric pressure can only be used in first fluting 8 and second fluting 9 department.

Be provided with the retaining member that is used for interior roller 5 to fix on fixed cover 3, the retaining member comprises nut 14 and bolt 15, has all seted up the opening on interior roller 5, outer roller 6 and the fixed cover 3, and bolt 15 passes the opening and fixes through nut 14.

Because outer roller 6 and fixed cover 3 sliding connection, therefore when bolt 15 and nut 14 separate, can the outer roller 6 of rotatory slip, make it misplace with interior roller 5, thereby can realize the dislocation of first fluting 8 and second fluting 9, because the air is actually from the coincidence department circulation of first fluting 8 and second fluting 9, thereby can adjust the size of circulation of air cross-section through the mutual dislocation of the two, can increase or reduce atmospheric pressure under the prerequisite of not adjusting fan 11 through the size of adjusting the cross-section.

The inner surface of the inner roller 5 is provided with a heat pipe 7, the heat pipe 7 adopts a hollow technical pipeline, heat-conducting media such as water, steam and the like can be filled in the heat pipe 7, the heat pipe 7 is connected with a heater 4 for supplying heat, the heater 4 can be arranged on the inner wall of the fixed sleeve 3 or the inner roller 5, the heater 4 can adopt an electric heater, and heat is uniformly transmitted to the heat pipe 7 through the heat-conducting media.

When the temperature of the heat pipe 7 is increased to be more than 55 degrees, the PLA (polylactic acid) textile product is subjected to thermal deformation shrinkage, gaps of the PLA textile product are reduced during the thermal deformation shrinkage, so that the PLA textile product can be adsorbed by negative pressure, other natural fibers or chemical fibers cannot be damaged at the temperature, and the PLA textile product can be effectively screened out.

In the present embodiment, the heat pipe 7 is disposed in an S-shape and is continuous between the first slots 8, and particularly referring to fig. 3, such an arrangement can make the heating of the heat pipe 7 more uniform.

The inner roller 5 is internally provided with a partition board which divides the inner space into an upper space and a lower space, the upper space is defined as 5a, the lower space is defined as 5b, the partition board is provided with a fan 11, the air inlet end of the fan 11 is positioned in the lower space 5b, and the air outlet end of the fan 11 is positioned in the upper space 5 a.

In this embodiment, the area of head space 5a is less than down space 5b, after so setting up, although the intake and the air output of fan 11 are balanced, the effect of supplementary pressure boost has been played in head space 5a space reduction for the fabrics has sufficient atmospheric pressure and can drive it and overturn to second conveyor components 13 on, and the effect of supplementary decompression has been played in the space reduction of head space 5b, avoids the fabrics excessively to adsorb on the surface of outer roller 6.

In this embodiment, the second conveying assembly 13 is disposed at the intersection of the upper space 5a and the lower space 5b, so that the textiles can be turned over on the second conveying assembly 13 under the pushing of the air pressure.

The heater 4 is started to set the temperature at 70-80 ℃ and preheat for 30 minutes, then the first conveying assembly 12, the second conveying assembly 13, the speed reducing motor and the fan 11 are started, the textile is laid flat on the first conveying assembly 12 and conveyed in a clearance mode, wherein when the polylactic acid textile 16a contacts with the outer roller 6, the outer roller 6 contracts due to the fact that the temperature of the outer roller 6 is 55 ℃ higher than the deformation temperature of the polylactic acid, at the moment, the gravity of the polylactic acid textile cannot overcome the air pressure, and the polylactic acid textile can be closely adsorbed on the surface of the outer roller 8 and conveyed to the upper side under the action of the external atmospheric pressure until the partition plate 10 is moved to be turned over to the second conveying assembly 13 by positive air pressure.

When the plain textile 16b is transported, however, the air flow can pass through the analysis due to the large gap of the plain textile, so that it is sucked up a little bit until its gravity is greater than atmospheric pressure, and falls off the outer roller 8.

In the present embodiment, the magnitude of the local air pressure at the second slot 9 can be adjusted by the following two aspects: firstly, the rotating speed of the fan 11, the shape and the size of the blade and the like are adjusted; secondly, the size of the overlapped area of the first slot 8 and the second slot 9 can be adjusted through the locking piece to control the local air pressure.

The above description is only a preferred embodiment of the present invention, and not intended to be exhaustive or to limit the scope of the present invention, and any person skilled in the art can substitute or change the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
