Description

Guide device capable of spatially staggered conveying and non-woven fabric forming and processing mechanism

Technical Field

The invention relates to the technical field of spinning, in particular to a guide device capable of realizing spatial dislocation conveying and a non-woven fabric forming and processing mechanism.

Background

After processing a strip-shaped material such as various woven fabrics, knitted fabrics, non-woven fabrics, and plastic films into a blank, in order to improve the physical properties and impart more functionality to the strip-shaped material, it is often necessary to perform subsequent processing treatments such as knife coating, padding finishing, and multi-layer lamination.

A coater such as that disclosed in application 201621432168.0, a safety type open-width padding machine such as that disclosed in application 201210109531.5, and a method for finishing cloth by padding. Further, as disclosed in patent application 201811188431.X, an antibacterial composite fabric and a preparation method thereof are disclosed, wherein the lower surface of a base fabric and the upper surface of an antibacterial composite layer are pressed together, and the lower surface of the antibacterial composite layer and the upper surface of a protective layer are pressed together to form a composite multilayer fabric.

As can be seen from the prior art blank post-processing method, currently, the same post-processing apparatus can only perform the same process in the same time period, but cannot perform post-processing of a plurality of different processes at the same time, which is determined by the characteristics of the conventional post-processing apparatus. If the base cloth is subjected to knife coating treatment, the device sequentially comprises a feeding device, a knife coating device, a drying device and a winding device according to the front and back sequence of the process flow, and a plurality of guide rollers, traction rollers, tension rollers and the like can be arranged in the process. Some processes further include a slitting device, such as a slitting machine disclosed in patent application 201510855061.0 and a cloth slitting cross-cutting machine disclosed in patent application 201811595801.1, for cutting the cloth into multiple sections of cloth strips with a set width on line. Cloth or post-processing treatment in a whole width mode, and slitting treatment according to the specification requirement of downstream products after winding; or before post-processing, the cloth is divided into strips, then the cloth strips are wound into cloth rolls, and then the cloth rolls are sent to a corresponding post-processing workshop (post-processing production line) for corresponding post-processing.

Therefore, it is necessary to configure independent post-processing production lines according to the types of products, that is, each production line includes not only a corresponding post-processing device but also a preceding feeding device, such as an unwinding device, and it is also necessary to wind a strip-shaped blank obtained by extrusion or melt-blowing or weaving with a weaving machine, then feed the wound blank roll into a feeding frame of the feeding device, and then perform post-processing. Therefore, when different products are obtained by adopting the same blank to carry out different post-treatment processes, the devices which need different post-treatment processes cannot be integrated in the front feeding working section, the operation coordination efficiency is low, and the technical problems of large occupied area and high device investment cost are brought along therewith.

As shown in fig. 1, the present invention is described by taking an example in which the number of the guide devices 22 is an odd number, specifically three, and includes a left guide device 221, a middle guide device 222, and a right guide device 223. In the view of fig. 2, the left guide 221, the middle guide 222, and the right guide 223 are sequentially disposed from left to right, and thus the number of the corresponding slitting knives 213 is two. Of course, the number of the guide devices 22 may be even, and the guide devices include a left guide device 221 and a right guide device 223, and the left guide device 221 and the right guide device 223 are arranged in order from left to right.

When the guide device 22 capable of conveying materials in a spatially staggered manner is adopted for conveying materials, when the materials do not need to be subjected to post-treatment of different processes, the guide rollers in the adjacent guide devices 22 are driven by the driving device to be mutually horizontal, the guide rollers in the adjacent guide devices 22 are contacted end to form an integral guide roller structure, the cutting rotating shaft 212 is rotated to enable the cutter head of the cutting knife 213 to rotate upwards to be far away from the cutting platform 211, the end part of the material 91 fed from a previous device such as a feeding device sequentially passes through the cutting platform 211 and the integral guide roller structure from front to back and then is wound in the winding roller of the intermediate treatment device corresponding to the intermediate guide device 222, and the material 91 continuously passing through the intermediate treatment device is wound through the winding roller winding motion of the intermediate guide device 222, so that the conventional post-treatment process is realized.

Then, the slitting shaft 212 is rotated so that the cutting head of the slitting knife 213 is rotated downward to a position where the material 91 can be slit. Then or by the winding movement of the winding roller of the intermediate treatment device, the material 91 is conveyed continuously backwards; or the end parts of the materials 91 suspended behind the integral guide roller structure are pulled manually in sequence, and the materials 91 are conveyed backwards continuously; or the end part of the material 91 suspended behind the integral guide roller structure extends into a traction device, such as a traction device of an intermediate processing device, and the material 91 is continuously conveyed backwards under the traction action of the traction device; the material 91 is cut into three sub-strips 92 under the action of the cutter heads of the two cutting knives 213, when the three sub-strips 92 pass through the integral guide roller structure for a certain length, the part of the three sub-strips 92 behind the integral guide roller structure freely falls behind the integral guide roller structure (if the three sub-strips are pre-wound in a winding roller of the intermediate processing device, then the three sub-strips 92 are unwound, if the three sub-strips are pre-drawn by the drawing device, then the three sub-strips 92 drawn behind the three sub-strips are drawn forwards), when the height difference is generated between the adjacent guide devices 22 by the driving of the driving device, namely the left guide device 221 moves downwards, the right guide device 223 moves upwards, one of the three sub-strips 92 cut by the cutting knives 213 moves downwards under the action of the left guide roller 2214 of the left guide device 221, and one moves upwards under the action of the right guide roller 2234 of the right guide device 223, one of the three sub-material strips 92 is still on the middle guide roller 2222 of the middle guide device 222, passes through the upper post-treatment device, the middle post-treatment device and the lower post-treatment device which are opposite to the left guide device 221, the middle guide device 222 and the right guide device 223 at the same time, is wound in the winding roller of the upper post-treatment device, the winding roller of the middle post-treatment device and the winding roller of the lower post-treatment device, and passes through the continuous winding of the winding roller of the upper post-treatment device, the winding roller of the middle post-treatment device and the winding roller of the lower post-treatment device, so that the material 91 is sequentially subjected to strip cutting, spatial dislocation guiding (the left guide device 221, the middle guide device 222 and the right guide device 223), different post-treatment device treatment (the upper post-treatment device, the lower post-treatment device, and the lower post-treatment device, intermediate post-processing device, lower post-processing device).

As shown in fig. 2 and 3, in some embodiments, the left guide device 221 includes a left support base 2211, a left support frame 2212, a left fixing base 2213, and a left guide roller 2214, and the left support frame 2212 and the left fixing base 2213 are fixed to the left support base 2211. The left end of the left guide roller 2214 is rotationally matched with the left fixed seat 2213. The left support 2212 is located below the left guide roller 2214, the top of the left support 2212 is in a left arc structure with an upward opening, the outer surface of the area limited in the left support 2212 in the left guide roller 2214 is in contact with the inner wall of the left arc structure, and the left guide roller 2214 can rotate relative to the left arc structure.

The middle guide device 222 includes a middle support base 2221, a middle guide roller 2222, a middle support frame 2223, an auxiliary middle guide roller 2224, and an auxiliary fixing seat 2225, wherein the middle support frame 2223 is fixed above the middle support base 2221, the auxiliary fixing seat 2225 is fixed below the middle support base 2221, and the auxiliary fixing seat 2225 is located behind the middle support base 2221. The middle guide roller 2222 is arranged on the middle support frame 2223, the top of the middle support frame 2223 is in a middle arc structure with an upward opening, the outer surface of the middle guide roller 2222 limited in the area of the middle support frame 2223 is in contact with the inner wall of the middle arc structure, and the middle guide roller 2222 can rotate relative to the middle arc structure; the left and right ends of the auxiliary intermediate guide rollers 2224 are respectively rotatably fitted to the corresponding auxiliary fixing seats 2225.

The right guide 223 includes a right support base 2231, a right support frame 2232, a right fixing base 2233, and a right guide roller 2234, wherein the right support frame 2232 and the right fixing base 2233 are fixed on the right support base 2231.

However, in the present invention, since the right guide roller 2234, the middle guide roller 2222, and the left guide roller 2214 need to be contacted end to form an integral guide roller structure when they are horizontal, it is impossible to provide fixed seats at both ends of the right guide roller 2234, both ends of the middle guide roller 2222, and both ends of the left guide roller 2214, and to stabilize each guide roller by rotatably fitting both ends of the right guide roller 2234, both ends of the middle guide roller 2222, and both ends of the left guide roller 2214 to the fixed seats.

In order to solve the above technical problem, the present invention adopts the structure that the above-mentioned guide devices 22 are matched with each other. Specifically, the right end face of the guide roller 2214 on the left side needs to be in contact with the left end face of the middle guide roller 2222, so the support frame 2212 on the left side is arranged below the guide roller 2214, the top of the support frame 2212 on the left side is of a left arc structure with an upward opening, the outer surface of the area limited in the support frame 2212 on the left side in the guide roller 2214 on the left side is in contact with the inner wall of the left arc structure, the guide roller 2214 on the left side can rotate relative to the left arc structure, and the left arc structure is matched with the left fixing seat 2213, so that the stability and the rotatability of the whole installation of the guide roller 2214 on the left side are achieved. While the stability and rotatability of the overall installation of the right-hand idler roll 2234 is the same.

Since the left and right end surfaces of the middle guide roller 2222 need to be in contact with the right end surface of the left guide roller 2214 and the left end surface of the right guide roller 2234, respectively, no fixing seats can be provided at either of the left and right ends. When the left guide roller 2214, the middle guide roller 2222 and the right guide roller 2234 are horizontally arranged to form the overall guide roller structure, the outer surface of the middle guide roller 2222 limited in the area of the middle support frame 2223 is in contact with the inner wall of the middle arc structure, and the middle guide roller 2222 can rotate relative to the middle arc structure, so that the rotation of the overall guide roller structure can be realized. After the left guide roller 2214, the middle guide roller 2222 and the right guide roller 2234 are displaced in the height direction, since the auxiliary middle guide roller 2224 is located behind the middle guide roller 2222 and is not interfered by the positions of the left guide roller 2214 and the right guide roller 2234, the auxiliary fixed seats 2225 may be provided at both ends of the auxiliary middle guide roller 2224, and the sub-material strips 92 required to pass through the middle guide device 222 may be guided by the auxiliary middle guide roller 2224 without being guided by the middle guide roller 2222.

In some embodiments, in order to further improve the guiding power of the material, the present invention may further include a first motor respectively disposed at the left end of the left guide roller 2214, one end of the auxiliary middle guide roller 2224, and the right end of the right guide roller 2234, and the first motor rotates to realize active rotation of the guide roller and the guide roller.

As shown in fig. 4 and 5, in some embodiments, when the relative friction between the material and the guide roller is small, the left guide device 221 does not include the left fixed seat 2213, and the left guide roller 2214 is fixed on the top of the left support frame 2212; the right guide 223 does not include a right fixed seat 2233, and the right guide roll 2234 is fixed to the top of the right support frame 2232. The middle guide device 222 does not include the auxiliary middle guide roller 2224 and the auxiliary fixing seat 2225, and the middle guide roller 2222 is fixed to the top of the middle support frame 2223.

As shown in fig. 5 and 6, in some embodiments, the driving device includes a left driving rack 231, a left driving gear 232, a right driving rack 233, a right driving gear 234, a first transmission gear 235, and a second transmission gear 236. The left drive rack 231 is fixed to the left support base 2211 and the left drive gear 232 is engaged with the left drive rack 231. The right drive rack 233 is fixed to the right support bed 2231 and the right drive gear 234 is in mesh with the right drive rack 233. The first transmission gear 235 and the second transmission gear 236 are meshed with each other. The first transmission gear 235 and the left driving gear 232 are fixed on the first rotating shaft 2371, and the second transmission gear 236 and the right driving gear 234 are fixed on the second rotating shaft 2372. The first rotating shaft 2371 and the second rotating shaft 2372 are both rotatably engaged with the frame 10.

Taking the case where the guide rollers of the adjacent guide devices 22 are horizontal in the initial state as an example, the fixed end of the second motor can be fixed on the frame 10 by connecting the output shaft end of the second motor to the second rotating shaft 2372. The second rotating shaft 2372 is driven to rotate through the forward rotation of the output shaft of the second motor, the second rotating shaft 2372 rotates to drive the right driving gear 234 to rotate, the right driving rack 233 is driven to move upwards to drive the right guide device 223 to move upwards integrally, meanwhile, the output shaft of the second motor rotates forward to drive the second driving gear 236 to rotate, the first driving gear 235 is used for reversing to drive the first rotating shaft 2371 to rotate reversely, the left driving gear 232 is driven to rotate reversely, the left driving rack 231 is driven to move downwards to drive the left guide device 221 to move downwards integrally, and the dislocation of the left guide device 221, the middle guide device 222 and the right guide device 223 in the vertical direction is realized.

Similarly, when the output shaft of the second motor rotates in the reverse direction, the left guide 221 moves upward as a whole and the right guide 223 moves downward as a whole, thereby leveling the left guide 221, the middle guide 222, and the right guide 223.

According to the invention, the guide rollers in the adjacent guide devices 22 can be in end-to-end contact to form an integral guide roller structure or the height difference is generated between the guide rollers in the adjacent guide devices 22 through the positive and negative rotation of the second motor, so that the guide roller structure has the technical effects of precise mechanical transmission and matching, convenience in operation and strong mechanical synergistic action.

As shown in fig. 6, in some embodiments, the number of the left driving racks 231 and the right driving racks 233 is multiple, and all the left driving racks 231 are connected by a left connecting rod 2381, and all the right driving racks 233 are connected by a right connecting rod 2382. The first rotation shaft 2371 is provided with the same number of left drive gears 232 as the number of left drive racks 231, and the second rotation shaft 2372 is provided with the same number of right drive gears 234 as the number of right drive racks 233.

According to the invention, the plurality of driving racks are arranged on the same guide device 22, so that the guide device 22 is stressed at multiple points simultaneously during movement, and the movement stability is further improved.

Further, a vertically-guided linear groove 101 is formed in the frame 10, and both ends of the left connecting rod 2381 and both ends of the right connecting rod 2382 respectively extend into the corresponding linear grooves 101 to be in sliding fit with the corresponding linear grooves 101 in the vertical direction. Thereby further improving the accuracy of the guidance.

As shown in fig. 7 and 8, in some embodiments, the slitting device 21 further includes a pressing roller 2141 and a pressing roller mounting bracket 2142, the pressing roller mounting bracket 2142 is located behind the slitting rotating shaft 212 and is rotatably engaged with the frame 10, the pressing roller 2141 is fixed on the front end of the pressing roller mounting bracket 2142 or the pressing roller 2141 is rotatably engaged with the front end of the pressing roller mounting bracket 2142. The spring 2143 is assembled such that the rear end of the pressing roller mounting bracket 2142 extends out of the rear end of the slitting platform 211 and is inclined downward and the pressing roller 2141 is located above the sub-material strip 92 slit by the slitting knife 213, and preferably, the spring 2143 is in a stretched state at this time.

A trigger block 25 is fixed on the right support base 2231, and the front sides of the upper and lower ends of the trigger block 25 are retreated backwards to form an upper step structure 251 and a lower step structure 252. When the right guide roller 2234 is moved upwards from the position horizontal to the middle guide roller 2222 and the left guide roller 2214 to the upper step structure 251 of the trigger block 25 is exposed upwards above the rear end of the press roller mounting bracket 2142, the front side of the trigger block 25 contacts with the rear end of the press roller mounting bracket 2142 to drive the rear end of the press roller mounting bracket 2142 to rotate upwards so that the press roller 2141 presses downwards on the sub-material strip 92 cut by the slitting knife 213, and when the right guide roller 2234 is moved upwards until the lower step structure 252 of the trigger block 25 is opposite to the rear end of the press roller mounting bracket 2142, the spring 2143 drives the press roller 2141 to reset by the current reset motion. When the right guide roller 2234 moves downward from a high position to a process that the right guide roller 2234 is horizontal to the middle guide roller 2222 and the left guide roller 2214, when the lower step structure 252 of the trigger block 25 is exposed downward below the rear end of the press roller mounting bracket 2142, the front side of the trigger block 25 contacts with the rear end of the press roller mounting bracket 2142 to drive the rear end of the press roller mounting bracket 2142 to rotate downward so that the press roller 2141 rotates upward, and when the right guide roller 2234 moves downward until the upper step structure 251 of the trigger block 25 is opposite to the rear end of the press roller mounting bracket 2142, the spring 2143 drives the press roller 2141 to reset by the current reset motion.

Thus, when a height difference between adjacent guide devices 22 needs to be generated, by the structure of the trigger block 25 and the cooperation of the trigger block and the press roll mounting bracket 2142, the press roll 2141 automatically presses down on the sub-material strips 92 cut by the cutting knife 213 on the cutting platform 211 in the process, so that the displacement portion of the sub-material strips 92 moving upwards along with the right guide roll 2234 can be ensured to be basically present in the portion falling behind the integral guide roll structure in advance, and the material in front of the integral guide roll structure can not be pulled. And when the right side guide roller 2234 moves in place, that is, the guide rollers in the adjacent guide devices 22 contact end to form the integral guide roller structure or a height difference is generated between the adjacent guide devices 22, the upper step structure 251 or the lower step structure 252 respectively face the press roller mounting bracket 2142 and do not interfere with the press roller mounting bracket 2142, and in each state after the right side guide roller 2234 moves in place, the press rollers 2141 are all located above the sub-material strips 92 cut by the slitting knife 213 and do not affect the conveying of the sub-material strips 92.

In some embodiments, the lengths of the upper step structure 251 and the lower step structure 252 are the same and occupy a smaller length of the trigger block 25.

In some embodiments, the spring 2143 is a tension spring, and its upper and lower ends are connected to the rear end of the pressing roller mounting bracket 2142 and the frame 10, respectively, and the tension spring is installed in a stretching manner such that the rear end of the pressing roller mounting bracket 2142 extends out of the rear end of the slitting platform 211 and is inclined downward, and the pressing roller 2141 is located above the sub-material strips 92 slit by the slitting knife 213. When the rear end of the platen roller mounting bracket 2142 rotates upward and the front end thereof rotates upward, the tensile amount of the tension spring increases, and when the rear end of the platen roller mounting bracket 2142 rotates downward and the front end thereof rotates upward, the tensile amount of the tension spring decreases.

In some embodiments, the front device, such as the feeding device, of the spatially offset conveyable guide 22 of the present invention is in a stopped state during the operation of generating a height difference between the guide rollers of the adjacent guide 22 by the guide rollers of the adjacent guide 22 contacting end to form an integral guide roller structure.

As shown in fig. 10, in some embodiments, the device further includes a linkage rod 291 and a swinging rod 292, one end of the swinging rod 292 is fixed on the slitting rotating shaft 212, the other end of the swinging rod 292 is hinged to one end of the linkage rod 291, and the other end of the linkage rod 291 is hinged to the right supporting bottom platform 2231. After ensuring that the right support base 2231 moves upward, the cutting spindle 212 rotates to a position where the cutting head of the cutting knife 213 rotates downward to cut the material 91.

Thus, the present invention achieves the cooperation of the rotation of the slitting knife 213 and the movement of the guide 22. When the guide rollers in the adjacent guide devices 22 are horizontal to each other, the cutter head of the slitting cutter 213 is far away from the slitting platform 211, when the driving device drives to cause the height difference between the adjacent guide devices 22, namely the right side supports the bottom table 2231 to move upwards, under the transmission action of the linkage rod 291, the swinging rod 292 can swing to cause the slitting rotating shaft 212 to rotate to the position where the cutter head of the slitting cutter 213 rotates downwards to slit the material 91, when the guide rollers in the adjacent guide devices 22 are horizontal to each other, the slitting cutter 213 automatically rotates to the avoiding position, and when the height difference is generated between the adjacent guide devices 22, the slitting cutter 213 automatically rotates to the slitting position, so that the control convenience of the whole machine and the cooperative integration of the devices are further improved.

Compared with the prior art, the guide device capable of spatially staggered conveying has the following technical effects: firstly, the guide device capable of spatial dislocation conveying is adopted as a link for connecting a front feeding device and a rear post-processing device, the guide rollers in the adjacent guide devices 22 are contacted end to form an integral guide roller structure, so that the traditional single post-processing technology can be met, and different post-processing technologies can be simultaneously carried out on the same material on the same production line through the height difference generated between the guide rollers in the adjacent guide devices 22, so that the effect of multiple use modes of the guide device can be achieved, the different post-processing technologies can be integrated, the cooperation of different post-processing devices can be realized by adopting the same feeding device, and the technical effects of improving the operation cooperation efficiency, reducing the occupied area of the device and the input cost of the device can be improved. Secondly, the guide device capable of conveying in a spatial staggered way not only can adopt a traditional feeding device comprising an unwinding roller, namely, materials needing post-treatment are wound in the unwinding roller and then are subjected to post-treatment. Furthermore, the plastic film or non-woven grey cloth processed by a former material forming device such as an extruder, a blow molding machine or a melt blowing machine can be fed without post-processing in a winding and re-feeding mode, namely, the grey cloth or film formed by the former processing can be directly conveyed to the guide device 22 capable of being conveyed in a space staggered mode without a process of winding and re-feeding (namely a blanking and feeding process), post-processing of different processes is carried out, and a grey cloth or film production device and a post-processing device are integrated, so that the integration effect of equipment is further improved. Thirdly, due to the characteristic that the height difference is generated between the guide rollers in the adjacent guide devices 22 by the driving of the driving device, and in combination with the working principle of the invention, when the height difference is generated between the adjacent guide devices 22 by the driving of the driving device, namely the left guide device 221 moves downwards and the right guide device 223 moves upwards, one of the three sub-material strips 92 cut by the cutting knife 213 moves downwards under the action of the downward movement of the left guide roller 2214 of the left guide device 221, and the other moves upwards under the action of the upward movement of the right guide roller 2234 of the right guide device 223, and the other sub-material strip is still on the middle guide roller 2222 of the middle guide device 222, so that the material strips with different heights can automatically move to the position opposite to the corresponding post-processing device along with the movement of the corresponding guide device 22, and particularly when the sub-material strip 92 is guided to the post-processing device at a high position, a worker does not need to stand to guide the sub-material strip 92 from a low position to a high position; the height difference generated between the guide rollers in the adjacent guide devices 22 can realize linear change, and the actual requirements of different factory spaces and working conditions are met. Fourthly, the invention realizes the coordination of the rotation of the slitting knife 213, the movement of the press roll and the movement of the guiding device 22. Thereby further improved the control convenience of complete machine and the collaborative integration of device. When the guide rollers in the adjacent guide devices 22 are horizontal to each other, the slitting knife 213 automatically rotates to the avoiding position, and when the height difference is generated between the adjacent guide devices 22, the slitting knife 213 automatically rotates to the slitting position. Because work as the drive arrangement drive causes the in-process that produces the difference in height between the adjacent guider, can link the compression roller and push down the motion and go on in proper order on sub-material strip and the motion is lifted to the linkage compression roller, the compression roller lifts up the back, different sub-material strips after cutting through dividing the cutter can loop through the compression roller and cut the clearance between the platform, different guider, can guarantee when each sub-material strip misplaces, the part of sub-material strip displacement can appear in the part at whole deflector roll structure's rear in advance basically, and can not drag the material in the place ahead of whole deflector roll structure.

Thus, when the slitting knife 213 rotates downwards until the knife head is inserted into the corresponding knife head mounting groove 2111, the left pressing block 2162 and the right pressing block 2163 move oppositely to squeeze the left side and the right side of the knife head of the slitting knife 213, so as to fasten the knife head and prevent the knife head from deviating in the slitting process.

Furthermore, a first internal thread through hole and a second internal thread through hole 21612 are formed at the end of the fastening screw rod 2161, a through hole is formed in the frame 10, when the slitting knife 213 rotates downwards until the knife head is inserted into the corresponding knife head mounting groove 2111, the first internal thread through hole is opposite to the through hole, and the screw part of the fastening bolt 2192 is screwed into the first internal thread through hole in a threaded fit manner and extends into the through hole, so that the fastening of the fastening screw rod 2161 is realized; when the cutting knife 213 rotates to the position that the knife head rotates upwards to the position that the knife head is far away from the corresponding knife head mounting groove 2111, the second internal thread through hole 21612 is opposite to the through hole, and the screw part of the fastening bolt 2192 is screwed into the second internal thread through hole 21612 in a threaded fit manner and extends into the through hole, so that the fastening of the fastening screw rod 2161 is realized.

The feeding device 1 is used for feeding the non-woven fabric into the guide device 2 capable of spatially staggered conveying. When the driving device drives to generate a height difference between the adjacent guide devices 22, different strips of the nonwoven fabric cut by the slitting knife 213 can pass through different guide devices 22 and be processed in different post-processing devices 3. When the drive means drives such that the guide rollers in adjacent guides 22 are horizontal to each other, the guide rollers in adjacent guides 22 make end-to-end contact to form an integral guide roller structure through which the nonwoven can pass and be treated in one of the aftertreatment devices 3.

The lower coater 33 is for coating the nonwoven fabric strip guided by the left guide 221.

The middle winder 321 is used for winding the nonwoven fabric guided by the integral guide roller structure when the driving device drives the guide rollers of the adjacent guide devices 22 to be horizontal to each other. Or the intermediate coater 322 is used to coat the nonwoven fabric guided by the integral guide roller structure.

Of course, the feeding device 1 of the present invention may also be a conventional feeding device including a feeding frame and an unwinding roller, wherein the unwinding roller wound with the gray fabric or the film (i.e. the material 91) is rotatably engaged with the feeding frame.
