[0029] Figure 1 , Figure 2 , Figure 3 and Figure 4 The shown built-in heat exchange device for a non-woven fabric setting machine comprises a non-woven fabric setting machine chamber 1 and a main setting roller 2 installed inside the non-woven fabric setting machine chamber 1, and side guide rollers 3 are movably mounted on the inner wall of the non-woven fabric setting machine chamber 1 on both sides of the main setting roller 2. The main setting roller 2 comprises a built-in heat exchange roller body 21 movably mounted on an axis inside the non-woven fabric setting machine chamber 1, a serpentine heat exchange flow channel 22 opened inside the built-in heat exchange roller body 21, a driving liquid pump 23 installed inside a rotating shaft on one side of the built-in heat exchange roller body 21, and an external driving unit fixed on the outer wall of the non-woven fabric setting machine chamber 1, and an external heat exchange cover is fixedly mounted on the inner top and bottom surfaces of the non-woven fabric setting machine chamber 1.

[0030] Working principle: The non-woven fabric is arranged along the upper surface of the main shaping roller 2, and then the side guide roller 3 is controlled to flip downward to adhere the non-woven fabric to the surface of the main shaping roller 2. The main shaping roller 2 is rotated to drive the non-woven fabric to be transported inside the non-woven fabric shaping chamber 1.

[0031] The side guide rollers 3 on both sides of the adjacent main shaping rollers 2 are arranged in an upper and lower staggered manner.

[0032] In order to cooperate with the flipping adjustment and thus control the fitting area between the non-woven fabric and the main shaping roller 2, the side guide roller 3 includes an annular guide bearing 31 fixed to the periphery of the assembly shaft on both sides of the main shaping roller 2, an external flipping arm 32 mounted on the annular guide bearing 31 through an outer cover shell, a side cloth guide roller 33 axially movably mounted on one side of the end of the external flipping arm 32, and a side support rod 34 for controlling the external flipping arm 32.

[0033] One end of the side support rod 34 is installed on the inner wall of the nonwoven fabric shaping machine chamber 1, and the extended end of the side support rod 34 is movably assembled with the external turning arm 32. The side support rod 34 controls the external turning arm 32 to turn and adjust by telescoping.

[0034] In order to cooperate with the driving, a lateral driving chamber 4 connected to the serpentine heat exchange channel 22 is opened inside the internal heat exchange roller body 21 and located inside the rotating shaft on one side.

[0035] In order to drive the internal heat exchange liquid, the driving liquid pump 23 includes a driving pump 231 fixed inside the rotating shaft on one side of the built-in heat exchange roller body 21 and an impeller 232 fixed by the output shaft of the driving pump 231. The impeller 232 is located inside the lateral driving chamber 4.

[0036] The driving pump 231 drives the impeller 232 to drive inside the lateral driving chamber 4 , thereby controlling the internal driving fluid to drive inside the serpentine heat exchange channel 22 .

[0037] In order to cooperate with external heat exchange, the external heat exchange cover includes an arc-shaped upper heat-conducting cover 5 fixed on the inner top surface of the non-woven fabric shaping machine chamber 1, an arc-shaped lower heat-conducting cover 6 fixed on the inner bottom surface of the non-woven fabric shaping machine chamber 1, a lateral air guide cover 7 fixed on the inner walls on both sides of the non-woven fabric shaping machine chamber 1, an outer drive cover 8 fixed on the side wall of the lateral air guide cover 7, and a guide drive mechanism 9 installed inside the outer drive cover 8.

[0038] In order to cooperate with the driving, the diversion driving mechanism 9 includes a lateral driving impeller 91 movably installed inside the outer driving cover 8 through an external rotating shaft and a linkage gear 92 axially fixed to the end of the external rotating shaft.

[0039] The linkage gear 92 rotates at high speed, thereby driving the lateral driving impeller 91 inside the outer driving cover 8 to control the driving of the heat exchange fluid inside the lateral air guide cover 7, and guides the heat exchange fluid inside the arc-shaped upper heat-conducting cover 5 into the arc-shaped lower heat-conducting cover 6 through the lateral air guide cover 7.

[0040] In order to cooperate with the synchronous drive, the two side walls of the main shaping roller 2 are provided with an annular gear frame 10 meshing with the linkage gear 92.

[0041] In order to avoid heat loss by turning sideways to fit on the outer side of the upper surface of the non-woven fabric, arc-shaped flow guide cover shells 11 are movably mounted on both sides of the arc-shaped upper heat-conducting cover 5 .

[0042] The arc-shaped flow guide shell 11 is turned downward and close to the periphery of the non-woven fabric, so as to quickly absorb the heat emitted by the non-woven fabric. The arc-shaped flow guide shells 11 on the adjacent main shaping rollers 2 are arranged in an upper and lower staggered manner.

[0043] In order to increase the heat exchange range, a lateral heat exchange channel 12 communicating with the interior of the arc-shaped upper heat-conducting cover 5 is provided inside the arc-shaped flow guide shell 11 .

[0044] Lateral assembly holes are symmetrically provided at both ends of the arc-shaped upper heat-conducting cover 5. The arc-shaped flow guide cover shell 11 is inserted into the lateral assembly holes through the flow guide pipe on the connecting arm to connect the internal movement of the arc-shaped upper heat-conducting cover 5. At this time, the arc-shaped upper heat-conducting cover 5, the arc-shaped lower heat-conducting cover 6, the lateral flow guide cover 7, the outer drive cover 8 and the arc-shaped flow guide cover shell 11 are connected in series, and the main shaping roller 2 drives the annular gear frame 10 to drive the linkage gear 92, and the lateral drive impeller 91 is driven to rotate through the linkage gear 92, thereby driving the heat exchange fluid located between the arc-shaped upper heat-conducting cover 5, the arc-shaped lower heat-conducting cover 6, the lateral flow guide cover 7, the outer drive cover 8 and the arc-shaped flow guide cover shell 11 to flow, and the heat at the upper end is introduced into the bottom, thereby conducting heat to the serpentine heat exchange flow channel 22 inside the built-in heat exchange roller body 21.

[0045] The diversion method is: the driving liquid of the first recirculation channel inside the lateral air guide cover 7 is drawn into the outer driving cover 8 by rotating the lateral driving impeller 91, and then driven to the first driving channel inside the lateral air guide cover 7 through the outer driving cover 8, and introduced into the arc-shaped lower heat-conducting cover 6 through the first driving channel, and then introduced into the arc-shaped upper heat-conducting cover 5 along the second recirculation channel through the heat exchange channel recirculation channel inside the arc-shaped lower heat-conducting cover 6, and then introduced into the lateral heat exchange channel 12 inside the arc-shaped air guide cover shell 11 on both sides through the arc-shaped upper heat-conducting cover 5, and then returned to the arc-shaped upper heat-conducting cover 5 through the lateral heat exchange channel 12, and then returned to the first recirculation channel inside the air guide cover 7 through the recirculation channel inside the arc-shaped upper heat-conducting cover 5, forming a circulation channel design.

[0046] In order to control the angle adjustment of the arc-shaped air guide shell 11 , an overhead driving support rod 13 is installed on the top surface of the non-woven fabric shaping chamber 1 .

[0047] One end of the top-mounted driving strut 13 is movably mounted on the top surface of the nonwoven fabric shaping machine chamber 1, and the extended end of the top-mounted driving strut 13 is movably assembled with the upper surface of the arc-shaped flow guide shell 11. The top-mounted driving strut 13 controls the flipping adjustment of the arc-shaped flow guide shell 11 by telescoping.
