[0001] The present invention relates to the technical field of compound interlining processing, and particularly to a pre-treatment device and process for heat setting of multi-layer compound interlining processing. Background Art

[0002] The interlining is based on woven fabrics, knitted fabrics and non-woven fabrics, and is made of thermoplastic high-molecular compounds and specially processed by special machinery. It is used in the inner layer of clothing to play a role in strengthening and stiffening. After bonding with the fabric, the entire composite product has a framework function, just like using steel bars and cement as the framework when building a house. Therefore, heat setting work needs to be carried out when it is used in different fields after combination.

[0003] However, in the actual use process, the inventor found that during setting, the compound interlining is manually placed on the setting device. Under manual operation, the compound interlining is arranged into the required wavy shape, and then the compound interlining and the setting device as a whole are sent into the internal of the high-temperature setting box for heating and setting. This process requires multiple people to operate simultaneously to complete the setting work of the compound interlining, resulting in low work efficiency and poor setting effect. Summary of the Invention

Before the compound interlining enters the support roller member, under the drive of the lifting mechanism, the support mechanism located on the second support plate moves to a preset position. The feeding mechanism sequentially feeds a plurality of support roller members into the support mechanism to complete the installation of the support roller members. Subsequently, the compound interlining will move along the guiding mechanism and achieve staggered docking on a plurality of support roller members, making the compound interlining wavy, that is, completing the setting work of the compound interlining.

[0030] Advantages of the present invention:

[0031] (1) In the present invention, by providing a variable pitch mechanism, a supporting mechanism and a guiding mechanism, the variable pitch mechanism includes a variable pitch component and a plurality of first supporting plates and second supporting plates connected to the variable pitch component. And a supporting mechanism for placing the supporting roller member is fixedly arranged on the first supporting plate, and a supporting mechanism for placing the supporting roller member is slidably arranged on the second supporting plate. Before the composite lining cloth enters the supporting roller member, the supporting mechanism located on the second supporting plate moves to a preset position driven by the lifting mechanism, and the feeding mechanism sequentially feeds a plurality of supporting roller members into the inside of the supporting mechanism to complete the installation of the supporting roller members. Subsequently, the composite lining cloth will move along the guiding mechanism and achieve staggered lapping on a plurality of supporting roller members, so that the composite lining cloth is in a wavy shape, that is, the shaping work of the composite lining cloth is completed. The automation degree is high. At the same time, the shaping effect of the composite lining cloth is good, the working efficiency of shaping the composite lining cloth is improved, and the problems that the traditional shaping of the composite lining cloth requires manual operation, has low working efficiency and poor shaping effect are solved;

[0032] (2) In the present invention, by providing a variable pitch mechanism in cooperation with a supporting mechanism, after the supporting roller member is placed on the supporting mechanism, a plurality of secondary hinge plates rotate driven by the first driving unit and change the relative positions of the plurality of first supporting plates and the second supporting plates, thereby changing the relative positions of the supporting mechanisms, so that the supporting roller members can be moved closer to or away from each other, and the distance between the supporting roller members can be adjusted for composite lining cloths of different sizes, which is convenient for subsequent shaping work. At the same time, after the supporting roller member is placed on the lower supporting block in the supporting mechanism, the supporting roller member presses against the control rod and drives the upper supporting block to rotate and cooperate with the lower supporting block, thereby realizing the placement and supporting work of the supporting roller member, and ensuring the stability of the supporting roller member during rotation or movement;

[0033] (3) In the present invention, by providing a lifting mechanism in cooperation with a supporting mechanism, the lifting mechanism includes a lifting component, a transmission component, and a control component. When it is necessary to adjust the size and shape of the composite lining cloth during shaping, the control component can be used to drive the transmission component to work. The transmission component will drive the lifting component to work and drive the supporting mechanism provided on the second support plate to lift, ensuring a good shaping effect of the composite lining cloth while also realizing the lifting of the support roller on the second support plate, thereby facilitating the adjustment of the size and shape of the composite lining cloth according to needs.

[0034] (4) In the present invention, by providing a guiding mechanism, the guiding mechanism includes an upper guiding component, a lower guiding component, an intermediate guiding component, an upper driving component, and a lower driving component. During operation, in order to enable the composite lining cloth to move smoothly along the required wavy track, the upper driving component drives the upper guiding component to descend to the position of the support roller in the first support plate, and the lower driving component drives the lower guiding component and the intermediate guiding component to move to the position of the support roller in the second support plate. Subsequently, the rotating mechanism drives the support roller to rotate, and the composite lining cloth located on the support roller will move forward under the combined action of the support roller, the upper guiding component, the lower guiding component, and the intermediate guiding component, and finally form the required wavy shape, thereby completing the preliminary shaping work.

[0035] In summary, the device has the advantages of high processing efficiency and good shaping effect for the composite lining cloth, and is particularly suitable for the technical field of composite lining cloth processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0060] Example 1

[0061] As shown in Figures 1-6 , a pre - treatment device for heat setting in the processing of multi - layer composite lining cloth includes:

[0062] A variable - pitch mechanism 1, with two sets of the variable - pitch mechanism 1 arranged oppositely. It includes a support frame 11, a variable - pitch component 12 arranged on the support frame 11, and a number of first support plates 13 and second support plates 14 connected to the variable - pitch component 12 and arranged alternately;

[0063] A support mechanism 2, with several groups of the support mechanism 2. Some of the support mechanism 2 are fixedly arranged at the upper end of the first support plate 13, and the remaining support mechanism 2 are slidably arranged at the lower end of the second support plate 14 through a lifting mechanism 3. The support mechanism 2 is used to place a support roller member 100 for receiving the composite lining cloth;

[0064] A guiding mechanism 4, which includes an upper guiding component 41 corresponding to the first support plate 13, a lower guiding component 42 corresponding to the second support plate 14, and an intermediate guiding component 43 hinged to the lower guiding component 42 and used to connect the upper guiding component 41 and the lower guiding component 42. The upper guiding component 41 and the lower guiding component 42 are respectively connected with an upper driving component 44 and a lower driving component 45;

[0065] Before the composite lining cloth enters the support roller member 100, the support mechanism 2 located on the second support plate 14 moves to a preset position driven by the lifting mechanism 3. The feeding mechanism 5 sequentially feeds a plurality of support roller members 100 into the interior of the support mechanism 2. After the guiding mechanism 4 moves to the preset position, the composite lining cloth will move along the guiding mechanism 4 and achieve staggered overlapping on a plurality of support roller members 100. Finally, the composite lining cloth is transported into the oven with the support roller member 100 to complete the setting work.

[0066] It is worth mentioning that the lining cloth can form a composite product with fabrics, main cloths, base cloths, etc., and then be applied in various fields. Different fields have different requirements for the form of the composite product; for example, curtains need to be set into a corrugated structure.

[0067] In this embodiment, by providing a variable pitch mechanism 1, a support mechanism 2, and a guiding mechanism 4, the variable pitch mechanism 1 includes a variable pitch assembly 12 and a plurality of first support plates 13 and second support plates 14 connected to the variable pitch assembly 12. A support mechanism 2 for placing the support roller member 100 is fixedly provided on the first support plate 13, and a support mechanism 2 for placing the support roller member 100 is slidably provided on the second support plate 14. Before the composite lining cloth enters the support roller member 100, it is necessary to transfer the variable pitch mechanism 1 and the plurality of support roller members 100 at its upper end to the unwinding station. Driven by the lifting mechanism 3, the support mechanism 2 located on the second support plate 14 moves to a preset position. The feeding mechanism 5 sequentially feeds the plurality of support roller members 100 into the interior of the support mechanism 2 to complete the installation of the support roller member 100. Subsequently, the composite lining cloth will move along the guiding mechanism 4 and achieve staggered lapping on the plurality of support roller members 100, making the composite lining cloth wavy, that is, the shaping work of the composite lining cloth is completed. The automation degree is high. At the same time, the shaping effect of the composite lining cloth is good, improving the working efficiency of the shaping of the composite lining cloth;

[0068] It should be noted that the feeding mechanism 5 includes a bracket 51, a transverse moving track 52 provided on the bracket 51, a lifting device 53 provided on the transverse moving track 52, and a clamping claw 54 provided at the lower end of the lifting device 53 and used for clamping the support roller member 100 (which can be driven by a motor). In use, the transverse moving track 52 drives the lifting device 53 and the clamping claw 54 to move to the stacking area where the support roller members 100 are stacked to clamp the support roller member 100, and then drives the support roller member 100 to the position corresponding to the first support plate 13 or the second support plate 14. After the lifting device 53 drives the clamping claw 54 and the support roller member 100 to descend to a height adapted to the support mechanism 2, the clamping claw 54 releases and places the support roller member 100 inside the support mechanism 2 to complete the feeding work of the support roller member 100;

[0069] In addition, before the composite lining cloth is sent to the shaping device, the composite lining cloth is arranged on a winding roller. When in use, the winding roller unwinds the composite lining cloth and transports it to the unwinding station in the shaping device. After a certain length of shaping work of the composite lining cloth is completed, it is also necessary for the cutting device at the rear end of the winding roller to cut off the composite lining cloth, separating the composite lining cloth on the winding roller from the composite lining cloth on the shaping device, facilitating the transfer of the shaping device and the composite lining cloth by the staff into the high-temperature shaping box, thereby realizing the shaping work of the composite lining cloth. The above processes are all prior arts. Therefore, the structures and working principles of the winding roller, the cutting device, and the high-temperature shaping box will not be described in detail.

[0070] Further, as Figures 3-6As shown, the pitch-changing assembly 12 includes a main hinge plate 121 fixedly arranged with the support frame 11, a plurality of secondary hinge plates 122 arranged in an interlaced manner and connected to the main hinge plate 121, and a first driving unit 123 connected to the first support plate 13 or the second support plate 14 far from the main hinge plate 121.

[0071] In this embodiment, by arranging the pitch-changing mechanism 1, after the support roller member 100 is placed on the support mechanism 2, driven by the first driving unit 123, a plurality of secondary hinge plates 122 rotate and change the relative positions of the plurality of first support plates 13 and the second support plates 14, and further change the relative positions of the support mechanism 2, so that the support roller members 100 can be moved closer to or away from each other, and the distance between the support roller members 100 can be adjusted for composite linings of different sizes.

[0072] Specifically, when it is necessary to change the distance between the first support plate 13 and the second support plate 14, the first driving unit 123 is controlled to work. The first driving unit 123 will drive the secondary hinge plate 122 connected thereto to move, thereby driving a plurality of secondary hinge plates 122 to move and rotate relative to each other simultaneously, and finally driving the plurality of first support plates 13 and the plurality of second support plates 14 to move synchronously by the same displacement distance.

[0073] It should be noted that the first support plate 13 connected to the main hinge plate 121 is fixed, and the remaining plurality of first support plates 13 and the plurality of second support plates 14 will move closer to or away from the first support plate 13 simultaneously. At the same time, the remaining first support plates 13 and second support plates 14 are all connected to the secondary hinge plates 122;

[0074] At the same time, in order to ensure the smoothness of the movement of the first support plate 13 and the second support plate 14, a slide rail is fixedly arranged on the support frame 11, and the first support plate 13 and the second support plate 14 are both slidably connected to the slide rail.

[0075] Further, as Figures 7-8 shown, the support mechanism 2 includes:

[0076] A lower support block 21, the lower support block 21 is arranged outside the first support plate 13 or the second support plate 14, and a lower groove 211 for placing the support roller member 100 is formed inside the lower support block 21;

[0077] An upper support block 22, the upper support block 22 is rotatably connected to the lower support block 21, and an upper groove 221 matched with the lower groove 211 is formed inside the upper support block 22;

[0078] The control rod 23, the control rod 23 is fixedly connected to the upper support block 22 and the other end of the control rod 23 extends into the lower support block 21 from the side and extends to the position of the lower groove 211, and a sliding groove corresponding to the control rod 23 is provided in the lower support block 21.

[0079] In this embodiment, by providing the support mechanism 2, after the support roller member 100 is placed on the lower support block 21 in the support mechanism 2, the support roller member 100 will press against the control rod 23 and drive the upper support block 22 to rotate and cooperate with the lower support block 21, thereby realizing the placement and support work of the support roller member 100 and ensuring the stability of the support roller member 100 during rotation or movement.

[0080] Specifically, taking the support mechanism 2 provided on the first support plate 13 as an example, the lower support block 21 is fixedly arranged on the outside of the first support plate 13. Before the feeding mechanism 5 feeds a plurality of support roller members 100 into the inside of the support mechanism 2, the upper support block 22 and the lower support block 21 are open. At this time, the end of the support roller member 100 will enter the inside of the lower groove 211. During the process of entering the lower groove 211, the support roller member 100 will press against the control rod 23 and drive the control rod 23 to rotate inside the sliding groove. At the same time, the control rod 23 will also drive the upper support block 22 to rotate synchronously and finally make the upper support block 22 abut against the lower support block 21. At this time, the lower groove 211 and the upper groove 221 are matched to form a circular groove, and the end of the support roller member 100 is limited inside the circular groove and will not shift axially except for rotation.

[0081] It should be noted that in order to ensure that when the support roller member 100 descends, the support roller member 100 can stably drive the control rod 23 to rotate, a limit block 231 is fixedly arranged on the control rod 23. When the upper support block 22 is separated from the lower support block 21, under the limiting action of the limit block 231, the upper support block 22 will not deflect greatly, and at the same time, the end of the control rod 23 extending into the sliding groove will also be located inside the lower groove 211 to ensure that when the support roller member 100 descends, the support roller member 100 can stably contact the control rod 23 and drive it to rotate.

[0082] Further, as Figures 9-11 shown, the lifting mechanism 3 includes:

[0083] A lifting component 31, the lifting component 31 includes a threaded rod 311 rotatably arranged on the outside of the second support plate 14 and drivingly arranged with the lower support block 21, and a guide rail 312 fixedly arranged on the outside of the second support plate 14 and cooperating with the lower support block 21;

[0084] A transmission assembly 32, the transmission assembly 32 includes a first bevel gear 321 fixedly connected to the threaded rod 311, a second bevel gear 322 engaged with the first bevel gear 321, and a transmission shaft unit 323 connecting multiple second bevel gears 322;

[0085] A control assembly 33, the control assembly 33 includes a worm gear 331 coaxially arranged with the second bevel gear 322, a worm 332 engaged with the worm gear 331, and a rotating handle 333 for controlling the rotation of the worm 332 and arranged at the lower end of the second support plate 14.

[0086] In this embodiment, by providing the lifting mechanism 3 in cooperation with the support mechanism 2, the lifting mechanism 3 includes a lifting assembly 31, a transmission assembly 32, and a control assembly 33. When it is necessary to adjust the size and shape of the composite lining fabric during shaping, the control assembly 33 can be used to drive the transmission assembly 32 to work. The transmission assembly 32 will drive the lifting assembly 31 to work and drive the support mechanism 2 arranged on the second support plate 14 to lift. While ensuring good shaping effect of the composite lining fabric, the lifting of the support roller 100 located on the second support plate 14 can also be realized, thereby facilitating the adjustment of the size and shape of the composite lining fabric according to needs.

[0087] Specifically, before placing the support roller 100 on the support mechanism 2, if it is necessary to adjust the height of the support mechanism 2 on the second support plate 14, it is necessary to first drive the rotating handle 333 to rotate. After the rotating handle 333 rotates, it will drive the worm 332 to rotate and drive the worm gear 331 to rotate. After the worm gear 331 rotates, it will drive the second bevel gear 322, the transmission shaft unit 323, and the first bevel gear 321 to rotate. After the first bevel gear 321 rotates, it will drive the threaded rod 311 to rotate and finally drive the support mechanism 2 threadedly engaged with the threaded rod 311 to perform a lifting movement. At the same time, during the rotation of the transmission shaft unit 323, it will also synchronously drive the first bevel gears 321 and threaded rods 311 at the lower ends of other second support plates 14 to rotate. Therefore, the support mechanisms 2 on multiple second support plates 14 will lift simultaneously to ensure the accuracy of the interval of the composite lining fabric during shaping.

[0088] It should be noted that the lower support block 21 located on the second support plate 14 is provided with an internal thread matching the threaded rod 311, and a guiding groove matching the guide rail 312 is also provided.

[0089] Furthermore, as Figure 11 shown, the transmission shaft unit 323 includes several fixing rods 3231 fixed to the second bevel gear 322 and connected to the second support plate 14, and an elastic unit 3232 connecting multiple fixing rods 3231.

[0090] In this embodiment, during the rotation of the transmission shaft unit 323, the distance between multiple second support plates 14 also changes. To ensure the normal use of the transmission shaft unit 323, the transmission shaft unit 323 is provided with several fixing rods 3231 and an elastic unit 3232 connecting the multiple fixing rods 3231. In this way, when the distance between the multiple second support plates 14 becomes smaller, the elastic unit 3232 between the multiple fixing rods 3231 will be compressed synchronously. The elastic unit 3232 can be composed of a buffer spring connecting adjacent two fixing rods 3231 and a compression rod arranged inside the buffer spring. This not only ensures the compression and reset properties of the elastic unit 3232 but also enables the elastic unit 3232 to rotate synchronously with the fixing rods 3231.

[0091] Further, as Figures 12-18 shown, the upper guiding assembly 41 includes an arc-shaped support plate 411 that cooperates with the support roller member 100 and several first rotating rollers 412 arranged in an array along the inner circumferential direction of the arc-shaped support plate 411;

[0092] The intermediate guiding assembly 43 includes two sets of telescopic plate units 431 connected to each other by several connecting plates, a telescopic hinge unit 432 arranged outside one of the telescopic plate units 431, and several second rotating rollers 433 arranged inside the telescopic plate units 431;

[0093] The lower driving assembly 45 includes a lifting unit 451 for controlling the lifting of the intermediate guiding assembly 43 and the lower guiding assembly 42 and a translation unit 452 for controlling the movement of the intermediate guiding assembly 43 and the lower guiding assembly 42 along the axial direction of the support roller member 100.

[0094] In this embodiment, by setting the guiding mechanism 4 to include an upper guiding assembly 41, a lower guiding assembly 42, an intermediate guiding assembly 43, an upper driving assembly 44, and a lower driving assembly 45, during operation, in order to enable the composite lining cloth to move smoothly along the required wavy track, the composite lining cloth located on the support roller member 100 will move forward under the combined action of the support roller member 100, the upper guiding assembly 41, the lower guiding assembly 42, and the intermediate guiding assembly 43, and finally form the required wavy shape, thereby completing the preliminary shaping work. It is worth mentioning that before the guiding mechanism 4 operates, the variable pitch mechanism 1 together with the multiple support roller members 100 at its upper end needs to be transferred to the unwinding station, and the guiding mechanism 4 and the rotating mechanism 6 are both arranged at the unwinding station.

[0095] Specifically, when the winding roller conveys the composite lining cloth onto the supporting roller member 100, the upper driving assembly 44 drives the upper guiding assembly 41 to descend to the position of the supporting roller member 100 in the first support plate 13, and the lower driving assembly 45 drives the lower guiding assembly 42 and the middle guiding assembly 43 to move to the position of the supporting roller member 100 in the second support plate 14. Subsequently, the rotating mechanism drives the supporting roller member 100 to rotate, and the composite lining cloth will first pass through the supporting roller member 100 and the upper guiding assembly 41. At this time, the composite lining cloth is transmitted forward between the supporting roller member 100 and a plurality of first rotating rollers 412 on the arc-shaped support plate 411. When it is conveyed to the middle guiding assembly 43, the composite lining cloth will continue to be conveyed forward between the telescopic plate unit 431 and the second rotating roller 433. At this time, the second rotating roller 433 mainly plays a role in supporting and guiding. When the composite lining cloth enters the lower guiding assembly 42, driven by the supporting roller member 100, the composite lining cloth will continue to move forward until it moves onto the last supporting roller member 100. At this time, the composite lining cloth is in a wavy shape. Subsequently, the pitch-changing mechanism 1 can work to make the distance between the plurality of first support plates 13 and the second support plates 14 smaller, so that the composite lining cloth on the plurality of supporting roller members 100 on the first support plate 13 is tightly arranged, and the composite lining cloth on the plurality of supporting roller members 100 on the second support plate 14 is tightly arranged. This can ensure that the composite lining cloth will not shift on the supporting roller member 100 during subsequent transportation and shaping processes, so as to ensure the shaping effect.

[0096] It should be noted that in order to prevent the middle guiding assembly 43 from interfering with the composite lining cloth when it disengages from the composite lining cloth, the lower driving assembly 45 is provided with a lifting unit 451 and a translation unit 452. When the lower driving assembly 45 drives the middle guiding assembly 43 and the lower guiding assembly 42 to retract, first the translation unit 452 works to drive the middle guiding assembly 43 and the lower guiding assembly 42 to offset outward, so that the middle guiding assembly 43 disengages from the composite lining cloth. Subsequently, the lifting unit 451 drives the middle guiding assembly 43 and the lower guiding assembly 42 to descend and retract.

[0097] Furthermore, as Figures 14-16 shown, the upper guiding assembly 41 and the middle guiding assembly 43 are connected to each other through a connecting member 46. The connecting member 46 includes an adsorption block 461 arranged on the arc-shaped support plate 411 and a connecting block 462 arranged on the telescopic plate unit 431 and adapted to the adsorption block 461.

[0098] In this embodiment, after the supporting roller member 100 follows the supporting mechanism 2 to move up and down, the distance between the supporting roller member 100 on the first support plate 13 and the supporting roller member 100 on the second support plate 14 will change. Therefore, it is necessary to change the length of the intermediate guiding component 43 to ensure that the intermediate guiding component 43 can be connected to the upper guiding component 41. Thus, the intermediate guiding component 43 is provided to include two sets of telescopic plate units 431 connected to each other by a plurality of connecting plates, and a telescopic hinge unit 432 provided outside one of the telescopic plate units 431. When the intermediate guiding component 43 moves upward to cooperate with the upper guiding component 41, first, the connecting block 462 (which can be an iron metal block) will be tightly adsorbed to the adsorption block 461 (which can be a magnet) to complete the end connection between the upper guiding component 41 and the intermediate guiding component 43. Subsequently, in order to move the lower guiding component 42 to a suitable position, during the process of the lower guiding component 42 and the intermediate guiding component 43 continuing to move upward, the telescopic hinge unit 432 in the intermediate guiding component 43 will be squeezed and compressed, and drive the telescopic plate unit 431 to contract and become shorter (at the same time, the intermediate guiding component 43 will also deflect relative to the lower guiding component 42);

[0099] Correspondingly, the operator can stretch and reset the telescopic hinge unit 432 to ensure normal operation next time.

[0100] It should be noted that the telescopic plate unit 431 includes a plurality of first telescopic plates 4311 connected to the telescopic hinge unit 432 and a second telescopic plate 4312 slidably disposed between the plurality of first telescopic plates 4311. Similar to the pitch-changing component 12, the first telescopic plates 4311 connected to the lower guiding component 42 in the telescopic plate unit 431 will not move when the telescopic hinge unit 432 is squeezed.

[0101] Embodiment Two

[0102] As Figures 19-21 shown, the same or corresponding components as those in Embodiment One adopt the corresponding reference numerals in Embodiment One. For the sake of simplicity, only the differences from Embodiment One will be described below. The difference between this Embodiment Two and Embodiment One lies in:

[0103] Further, the supporting roller member 100 includes a roller shaft 110 for receiving the composite lining cloth, an intermediate shaft 120 coaxially arranged with the roller shaft 110, and a rotating gear 130 arranged on one side of the intermediate shaft 120. A rotating mechanism 6 for driving the supporting roller member 100 to rotate is further provided at the upper end of the supporting roller member 100.

[0104] It is worth mentioning that by setting the rotating mechanism 6 to cooperate with the supporting roller member 100, the normal rotation of the supporting roller member 100 can be driven to ensure the normal conveying work of the composite lining cloth. Specifically, the rotating mechanism 6 includes a second driving unit 61, a driving gear 62 connected to the second driving unit 61 for conveying and cooperating with the conveying rotating gear 130, and a control device 63 for controlling the lifting of the second driving unit 61.

[0105] Specifically, during operation, after the control assembly 33 moves the second driving unit 61 and the driving gear 62 to appropriate positions, the second driving unit 61 controls the driving gear 62 to rotate, which can drive the rotating gear 130 to rotate, and the rotating gear 130 can drive the composite lining cloth to move. Since there are multiple supporting roller members 100, accordingly, multiple second driving units 61 and driving gears 62 need to be provided at the lower end of the control device 63. The control device 63 can select commonly used lifting or translation equipment, and its specific structure will not be elaborated here.

[0106] Embodiment 3

[0107] As Figure 22 shown, a processing technology of a multi-layer composite lining cloth pre-treatment device before heat setting includes the following steps:

[0108] Step 1, adjustment process. After the variable pitch assembly 12 works to drive the first support plate 13 and the second support plate 14 to expand to appropriate positions, the lifting mechanism 3 works and drives the support mechanism 2 located on the second support plate 14 to move to an appropriate height.

[0109] Step 2, roll feeding process. The feeding mechanism 5 works and sequentially places the supporting roller members 100 on multiple support mechanisms 2.

[0110] Step 3, guiding process. The upper driving component 44 drives the upper guiding component 41 to descend to the position of the supporting roller member 100 in the first support plate 13, and the lower driving component 45 drives the lower guiding component 42 and the middle guiding component 43 to move to the position of the supporting roller member 100 in the second support plate 14, thereby completing the positioning work of the guiding mechanism 4.

[0111] Step 4, cloth feeding process. The rotating mechanism 6 descends and controls the rotating gear 130 to rotate through the second driving unit 61, thereby driving the supporting roller member 100 to rotate, and then completing the conveying work of the composite lining cloth between the supporting roller member 100 and the guiding mechanism 4.
