Technical Field

[0001] The present invention relates to the technical field of garment fabric processing, in particular to fully automatic gluing and hemming hot pressing equipment and a process for garment fabric. Background Art

[0002] In the field of clothing production, traditional sewing and splicing techniques are currently used to connect and secure cut pieces. However, for intimate apparel and clothing worn for extended periods of time, such as marathon running gear and basketball uniforms, the presence of seams often introduces a certain risk of friction. With the continuous development and advancement of technology, the demand for seamless (threadless) bonding technology is increasing in the apparel industry. This technology not only effectively avoids seam friction but also significantly enhances the aesthetics of garments, making it a popular choice among consumers.

[0003] Since this type of clothing fabric is relatively soft, it is difficult for its hems to form stable creases and cannot form continuous coordination with the front-end gluing station and the back-end hot pressing station to achieve automated production. At present, most of these stations rely on manual operation. Since the fabric is soft and difficult to fold and shape, manual operation is extremely difficult, inefficient, and the quality is difficult to guarantee. In particular, for the hem bonding of parts such as collars, cuffs, and hems, these parts have extremely high requirements for the comfort and aesthetics of clothing. Both hem bonding and hot pressing face great challenges. Therefore, how to improve the reliability and efficiency of the seamless hem bonding process for this type of fabric with the assistance of automated equipment has become a key issue that needs to be solved urgently in this field. Summary of the Invention

[0010] Preferably, the cleaning mechanism includes a push unit installed on the workbench, a first mounting plate slidably arranged on the workbench, and a rotatable cleaning member installed on the first mounting plate. The cleaning member extends under the dispensing head and cleans in an oblique rotating wiping manner.

[0011] Preferably, a positioning mechanism is provided at least at the feed end of the conveying mechanism, and the positioning mechanism includes two groups of auxiliary pressure wheels arranged at intervals, one group is arranged on the same side as the folding device, and the auxiliary pressure wheels are provided with a plurality of tooth structures on the circumference to realize rolling point pressure on the fabric, so that the fabric does not undergo isotropic deformation during the transmission process.

[0012] The tooth tops of the tooth structure of the auxiliary pressing wheel are all arranged in the same oblique direction, the tangential direction thereof is opposite to the rotation direction, and the rotation direction thereof is opposite to the rotation direction of the conveying mechanism.

[0013] Preferably, the dispensing machine, the hot press and the positioning mechanism are mounted on the workbench via a lifting mechanism, and are driven by the lifting mechanism to achieve synchronous lifting movements; The lifting mechanism includes a frame mounted on the workbench, a driving unit mounted on the frame, and a mounting frame driven by the driving unit to move vertically back and forth; The dispensing machine, hot press and positioning mechanism are respectively installed on the mounting frame through the connecting frame a.

[0014] Preferably, a fine-tuning mechanism is provided above the hot press, and the fine-tuning mechanism includes a power adjustment unit installed on the corresponding connecting frame and a floating adjustment unit movably placed on the output end of the power adjustment unit. When the power adjustment unit moves downward, the floating adjustment unit synchronously drives the hot press downward under its elastic action, exerting a downward pressure on the fabric.

[0015] Preferably, the conveying mechanism realizes traction and conveying of the fabric by negative pressure adsorption.

[0016] In view of the shortcomings of the prior art, the present invention further provides a fully automatic gluing and hemming hot pressing process for clothing fabrics, comprising the following steps: Step 1: When the fabric is transported by the conveying mechanism through the glue dispensing station, the glue dispensing machine simultaneously applies glue continuously and evenly to the glued part of the fabric to be folded; Step 2: The feeding end of the folding station is located at the front end of the gluing station. After the gluing is completed, the fabric is continuously conveyed backward through the conveying mechanism, passes through the folding device in turn, and forms two folded edges under its guidance; Step 3: After the folding is completed, the fabric is transported back to the hot pressing channel of the hot pressing station, and the fabric is automatically output after being hot-pressed and shaped by the hot press.

[0018] Preferably, a cleaning station is provided on one side of the dispensing station, so that when the dispensing station stops working, the dispensing head of the dispensing machine can be cleaned by moving to the dispensing station.

[0019] The beneficial effects of the present invention are: 1. The present invention integrates a glue dispenser, a hemming device and a hot press into one body and is installed on a workbench. The functional structures are reasonably optimized and arranged in accordance with the sequence of workstations. The layout is compact and the fabric conveying distance between the workstations is short. The fabric can be conveyed by the conveying mechanism and sequentially passed through the glue dispenser, the hemming device and the hot press to automatically complete glue dispensing, hemming and hot pressing bonding, and then automatically output, thereby improving the degree of automation and production efficiency. At the same time, the integrated setting and the layout of the various structures also reduce the possibility of deformation of the fabric during the transmission process, which is more conducive to the stable quality of glue dispensing and hemming shaping, thereby greatly improving the hemming shaping quality. 2. The present invention sets a folding device to ensure that the fabric is automatically folded in the process of being conveyed forward, and designs its structure into a smooth transition shape from the feed end to the discharge end in the form of horizontal-arc-curled, which realizes two automatic folding of the fabric side edges, so that the edge of the cut piece is folded inside the middle.

[0020] 3. The present invention further provides a positioning mechanism at the feed end of the conveying mechanism. The positioning mechanism includes two sets of auxiliary pressure wheels arranged at intervals, one set being arranged on the same side as the hemming device. The auxiliary pressure wheels are provided with a plurality of tooth-shaped structures on the circumference to achieve a rolling point pressure effect on the fabric, so that the fabric does not deform in all directions during the conveying process, the conveying is stable, and the dispensing quality and hemming quality are improved, thereby solving the problem that soft fabrics are difficult to fold and shape and the hemming part is easily wrinkled due to fabric deformation; 4. The present invention integrates the dispensing machine, hot press and positioning mechanism into a lifting mechanism to achieve consistency in the movements of each station, further improving the equipment integration and automation level and the stability of the overall operation. In addition, the control instructions are simplified, the efficiency is improved, the cost is reduced, and energy saving and consumption reduction, green environmental protection are further achieved; 5. The present invention adds a fine-tuning mechanism to the heat press and adopts a floating adjustment method to achieve a two-stage downward movement of the heat press, which improves work efficiency. In combination with the floating adjustment unit, the elastic action of the floating adjustment unit synchronously drives the heat press to move further downward, exerting a certain downward force on the fabric to ensure the hot pressing and bonding quality of the folded part; 6. The present invention also has a cleaning mechanism, which is arranged in a horizontally movable manner to adapt to the working rhythm of the dispensing machine. It is controlled to move horizontally to the bottom of the dispensing head when the dispensing machine stops working and resets, and the cleaning part is started to automatically clean it in an oblique rotating wiping manner, with a good cleaning effect.

[0021] In summary, the present invention is particularly aimed at the gluing, hemming and hot pressing bonding of soft fabric pieces, and has the advantages of good gluing uniformity, precise hemming and high degree of automation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0025] Example 1 like Figure 1-4 As shown, this embodiment provides a fully automatic gluing and hemming hot pressing device for clothing fabrics, comprising a workbench 1 and a conveying mechanism 2 mounted on the workbench 1 for conveying the fabrics forward, and further comprising: The folding device 4 is provided on the workbench 1 and is located on one side of the conveying mechanism 2; The glue dispenser 3 is located above the conveying mechanism 2 and is arranged near the feeding end of the hemming device 4; and The hot press 5 is located directly above the conveying mechanism 2 and is arranged at the discharge end of the hemming device 4; The fabric 100 is conveyed by the conveying mechanism 2 and sequentially passes through the glue dispenser 3, the edge folding device 4, and the hot press 5 to automatically complete the glue dispensing, edge folding, and hot pressing bonding, and then is automatically output.

[0026] In this embodiment, Figure 3 、 Figure 9 As shown, the conveying mechanism 2 realizes traction and conveying of the fabric 100 by negative pressure adsorption. Specifically, the conveying mechanism 2 includes a belt conveyor 21, a sealed chamber 22 located inside the belt conveyor 21, and a negative pressure generator connected to the inside of the sealed chamber 22. The upper plate of the sealed chamber 22 is provided with a through hole a20, and the belt of the belt conveyor 21 is evenly provided with through holes b. When the negative pressure generator is started, the negative pressure acts through the through holes a20 and the through holes b to adsorb the lower surface of the fabric, so that the fabric is firmly attached to the belt conveyor 21 and can be stably transmitted under the traction of the belt conveyor 21.

[0027] Among them, as a further design of the structure, an elastic pressure plate 24 is provided at the input end and the output end of the belt conveyor. The elastic pressure plate is obliquely pressed against the belt of the belt conveyor, so that the belt maintains a certain tension, so as to achieve a close fit between the belt and the upper surface of the sealing chamber 22, thereby improving the effect of negative pressure adsorption on the fabric.

[0028] Further, if Figure 4 、 6 As shown, the hemming device 4 includes a hemming plate body 41 placed on the conveying mechanism 2 and a hemming forming portion 42 extending outward from the hemming plate body 41. The hemming forming portion 42 gradually rolls inward along the conveying direction of the fabric 100 to form a hemming channel 40. The hemming plate body 41 and the hemming forming portion 42 are integrally formed so that the hemming channel 40 fits the side edge of the conveying mechanism 2, ensuring that the hemmed fabric can at least fall onto the conveying mechanism 2 so that it can be stably output.

[0029] Among them, the feed end 402 of the folding device 4 is horizontal, and the cross-sectional shape of the discharge end 403 is E-shaped. The folding device 4 is an integrated structure, and it presents a smooth transition form of horizontal-arc-curled from the feed end to the discharge end in sequence, so as to realize that the fabric is automatically pulled by the conveying mechanism 2 and the guiding cooperation of the folding channel 40 to automatically complete two foldings and maintain the shape before entering the hot pressing and bonding molding output.

[0030] Among them, the width of the folding plate body is not less than the width of the fabric required for gluing, and the fabric requires gluing parts to support and guide, so that the gluing quality of the fabric requires gluing parts is consistent.

[0031] Specifically, the width of the folding plate body can be set to be equal to or slightly larger than the required glue coating width. The glue dispensing machine is set on the same side as the folding device 4, and its glue dispensing head can be optionally set in the middle of the width direction of the required glue coating area to ensure the uniformity and consistency of the glue coating and prevent the glue from being coated outside the folding area.

[0032] In addition, the width of the hem forming portion is no greater than twice the width of the single hem required for the fabric. Specifically, the edge of the fabric portion to be hemmed is consistent with the outer edge of the hem forming portion or is slightly located inside the outer edge of the hem forming portion, so that the edge of the fabric piece can be folded inside after being hemmed and formed by the hem channel 40, thereby improving the quality and aesthetics of the fabric hem. Of course, when adjusting the size and shape of the discharge end of the hem channel 40, the edge of the fabric portion to be hemmed can also be slightly located outside the outer edge of the hem forming portion, so that the edge of the fabric piece is folded in the middle.

[0033] In this embodiment, the discharge end of the folding channel 40 is in the E-shape, which is composed of the folding forming part 42 rolled inward and the folding plate body 41. At the same time, the width dimension of the folding forming part 42 after rolling inward is not greater than the width dimension of the folding plate body 41, ensuring the initial bonding quality of the fabric after folding and forming, so as to facilitate subsequent hot pressing bonding.

[0034] In some embodiments, a horizontal guide member may be further provided inside the folding device 4, which is adapted to the folding channel 40 and can be set near the feed end of the folding channel 40 to support the fabric in the inward rolling state to avoid the fabric drooping due to being too soft and not yet formed.

[0035] Further, if Figure 9-10 As shown, a cleaning mechanism 9 is also included, which is movably arranged on one side of the glue dispensing machine 3 so as to move to the bottom of the glue dispensing machine 3 to clean its glue dispensing head 30 when the glue dispensing machine 3 stops working.

[0036] Specifically, the cleaning mechanism 9 includes a horizontal pushing unit 91 installed on the workbench 1, a first mounting plate 92 slidingly arranged on the workbench 1, and a cleaning member 94 installed on the first mounting plate 92 and capable of rotating. The cleaning member 94 extends under the dispensing head 30 to clean in an oblique rotating wiping manner. The front end of the cleaning member 94 extends beyond the dispensing head 30 to ensure that the dispensing head 30 is basically completely in contact with the cleaning member 94, thereby ensuring the cleaning effect.

[0037] Among them, the first mounting plate 92 is provided with a plurality of guide shafts 93 and two groups of pneumatic shafts, one group is installed on the cleaning part material tray, and the other group is installed on the recovery tray. The pneumatic shafts installed on the recovery tray are driven to rotate by a motor. The cleaning part 94 is preferably a dust-free cloth, which is output from the material tray and guided by a plurality of guide shafts 93 to maintain a certain tension state between the material tray and the recovery tray.

[0038] The present invention does not limit the structure of the glue dispenser 3. The glue dispenser 3, including the glue cylinder 31 and the glue dispensing head 30, can be any type of device capable of evenly coating the fabric with glue. This type of device is particularly common in the garment industry, particularly in seamless (seamless) bonding processes. The present invention does not further elaborate on its specific structure and function.

[0039] The present invention also features a cleaning mechanism that is horizontally movable to match the dispenser's operating rhythm. When the dispenser stops and resets, it moves horizontally below the dispensing head, activating the cleaning element to automatically clean it with an oblique, rotating wipe. This ensures that the dust-free cloth is always clean and can be automatically replaced after wiping, ensuring optimal cleaning results. Furthermore, the oblique contact arrangement allows the dust-free cloth to almost completely cover the dispensing head through its tension, improving cleaning effectiveness.

[0040] Example 2 The components that are the same or corresponding to those in the first embodiment are marked with the same reference numerals as those in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that: Figure 4 、 Figure 7-8 As shown, in this embodiment, a positioning mechanism 6 is provided at least at the feed end of the conveying mechanism 2. The positioning mechanism 6 is provided close to the input end of the folding device 4 and acts on the fabric 100 by a rolling point pressure method, so that the fabric 100 does not undergo isotropic deformation during the transmission process, thereby ensuring the folding quality.

[0041] For softer fabrics such as marathon jogging suits and basketball uniforms, which have greater elasticity and are prone to deformation and wrinkles during transmission through the conveying mechanism, the positioning mechanism 6 described in this embodiment includes two groups of auxiliary pressure wheels 63 set at intervals, and a number of tooth structures 60 are evenly distributed on the outer circumference of the auxiliary pressure wheel 63. The top teeth of the tooth structure 60 are all set in the same oblique direction, and their tangential direction is opposite to the rotation direction. When the tooth structure 60 is in contact with the fabric, the oblique direction of its tooth top is toward the input end of the fabric; the auxiliary pressure wheel 63 is driven by the conveying mechanism 2 to passively rotate, and the rotation direction is opposite to the rotation direction of the conveying mechanism 2, so that the auxiliary pressure wheel 63 transmits the fabric in a point-first and line-later manner. The fabric will not be stretched and deformed during the transmission process, ensuring the isotropic consistency of the fabric.

[0042] It should be noted that, as a preference, one group is arranged on the same side as the folding device 4, and the other group is arranged close to the edge of the conveying mechanism 2, so that the fabric can be stretched and not deformed at least at the gluing position, so as to facilitate the uniform coating effect of the glue; of course, since the size of the folding forming part 42 corresponding to the fabric piece is also relatively narrow, the auxiliary pressure wheel 63 is arranged close to the folding forming part 42 in the width direction, which also has a better expansion and positioning effect on the folding part of the fabric piece, so as to facilitate the folding quality.

[0043] In other words, by utilizing the consistency of its transmission linearity, the fabric can be stably conveyed to the folding channel in the folding device 4, reducing the possibility of deformation of the fabric and further ensuring the folding quality; and then utilizing another set of edge settings close to the conveying mechanism 2 to achieve the setting of the positions of the two sets of auxiliary pressure wheels to meet the requirement that the part of the fabric to be folded can remain expanded in the width direction.

[0044] In this embodiment, a positioning mechanism 6 is provided to ensure that the fabric is smoothly delivered to the feed end 402 of the hemming device 4 by the positioning mechanism 6 and automatically completed with two hemming operations under the automatic traction of the conveying mechanism 2 and the guidance of the hemming channel 40 and maintained in a fixed shape before entering into hot pressing and bonding molding output, so as to achieve a more beautiful and stable quality of fabric hemming processing.

[0045] Specifically, the positioning mechanism 6 also includes a mounting seat 61, a connecting shaft 62 provided on the mounting seat 61 and perpendicular to the conveying direction of the conveying mechanism 2, and an auxiliary pressure wheel 63 provided on the connecting shaft 62; in order to realize the passive transmission of the auxiliary pressure wheel 63 by the conveying mechanism 2, the connecting shaft 62 can be rotatably installed on the mounting seat 61 or the auxiliary pressure wheel 63 can be rotatably installed on the connecting shaft 62, and this embodiment does not impose specific restrictions.

[0046] In some embodiments, a positioning mechanism 6 can be further provided between the folding device 4 and the hot press 5 to further ensure that the fabric 100 does not undergo isotropic deformation before entering the hot pressing station, thereby improving the accuracy and quality of hot pressing. On the other hand, two sets of positioning mechanisms 6 are arranged in coordination so that the fabric glued to the folding station is positioned at the head and tail, and the transmission state is unique and stable.

[0047] Example 3 The same or corresponding components as those in the second embodiment are marked with the same reference numerals as those in the second embodiment. For the sake of simplicity, only the differences from the second embodiment are described below. The differences between the third embodiment and the second embodiment are: Further, if Figure 3 、 Figure 9 As shown, the dispensing machine 3, the hot press 5 and the positioning mechanism 6 are installed on the workbench 1 through the lifting mechanism 7, and are driven by the lifting mechanism 7 to achieve synchronous lifting action; The lifting mechanism 7 includes a frame 70 provided on the workbench 1, a driving unit 72 installed on the frame 70, and a mounting frame 73 driven by the driving unit 72 to move vertically back and forth; The dispensing machine 3, the hot press 5 and the positioning mechanism 6 are respectively installed on the mounting frame 73 through the connecting frame a74.

[0048] In this embodiment, a lifting mechanism 7 is provided to synchronously drive the glue dispenser 3, the folding device 4 and the hot press 5 to rise and fall. At the beginning of the initial work, after the fabric is adsorbed on the belt conveyor, the lifting mechanism 7 is started to lower the glue dispenser 3, the positioning mechanism 6 and the hot press 5 to the upper end of the fabric and contact the fabric.

[0049] In this embodiment, the frame 70 includes a main support frame 701 installed on the workbench 1 and a bracket 702 installed on the main support frame. The driving unit 72 adopts a screw transmission unit. After the screw transmission unit is started, it is transmitted through the mounting frame 73. The moving mounting frame 73 then drives the glue cylinder 311, the mounting seat 61 and the guide rail 81 to descend through three sets of connecting frames 74, thereby realizing the glue dispensing machine 3, the positioning mechanism 6 and the hot press 5 to descend to the upper end of the fabric and contact the fabric, and always position and keep in contact with the fabric during the fabric transmission process.

[0050] In this embodiment, the heat press 5 includes a housing 56, a transmission assembly 57 rotatably mounted on the housing 56, and a driving member 58 for driving the transmission assembly 57. The driving member 58 preferably comprises a universal coupling 581 with one end mounted on the main support frame 701 and the other end connected to the transmission assembly 57. A servo motor 582 drives the universal coupling 581 synchronously via a belt drive. Furthermore, the transmission assembly 57 includes a rotary pressure conveyor belt that is synchronously conveyed with the conveying mechanism 2. An electric heating element 50 is provided in the interior of the pressure conveyor belt to achieve synchronous conveying and hot-pressing bonding of the fabrics.

[0051] In this embodiment, a fine-tuning mechanism 8 is further provided above the hot press 5. The fine-tuning mechanism 8 includes a power adjustment unit 81 installed on the corresponding connecting frame 74 and a floating adjustment unit 82 movably placed on the output end of the power adjustment unit 81. The hot press 5 is connected to the elastic free end of the floating adjustment unit 82. When the power adjustment unit 81 moves downward, the floating adjustment unit 82 synchronously drives the hot press 5 to move downward under its elastic action, further applying a downward pressure on the fabric, so that the hot press 5 maintains a certain appropriate pressing force on the fabric on the conveying mechanism 2, thereby ensuring the quality of hot pressing bonding.

[0052] Among them, the power adjustment unit 81 includes a guide rail 811 installed on the corresponding connecting frame 74, a guide block 812 slidingly cooperated with the guide rail, a bracket 813 installed on the guide block 812 and a driving assembly 814. The driving assembly is preferably a screw-nut transmission method, including a screw vertically passed through the guide rail 811, a nut cooperated with the screw transmission and arranged inside the guide block 812, and a motor that drives the screw to rotate. This transmission method is a conventional transmission structure in this field, and the specific structure is not drawn in the figure; of course, other transmission methods can also be used.

[0053] The floating adjustment unit 82 includes a support 821 mounted on the main support frame, a guide member 822 vertically mounted on the support 51, an elastic member 823 sleeved on the guide member 822, a support seat 824 connected to the lower end of the elastic member 823, a guide seat 825 connected to the lower end of the guide member 822, and a guide post 826 slidably sleeved on the guide seat 825, with its ends respectively connected to the support seat 824 and the housing 51 of the hot press 5. The guide seat 825 is laterally mounted on the main support frame 701 and is equipped with two guide sleeves adapted to the size of the housing 51 of the hot press 5. Each guide sleeve is equipped with a guide post 826. The elastic member 823 is a compression spring.

[0054] In the present application, by setting a lifting mechanism 7 and cooperating with a fine-tuning mechanism 8, the hot press 5 is lowered twice. The first downward pressure quickly lowers the hot press 5 to a certain height position, and then the elastic force is used to lower the hot press 5 to the upper end of the fabric, avoiding excessive pressure on the hot press 5 and damage to the fabric transmission, and the hot press 5 is pressed stably.

[0055] In detail, the hot press 5 descends rapidly through the lifting mechanism 7, and then the guide block 812 descends along the guide rail 811, and the guide block 812 drives the bracket 813 to descend, and then the elastic member 823 in the compressed state is automatically and slowly released, and the elastic member 823 pushes the supporting seat 824 to descend, and the guide column 826 is slidably set on the shaft sleeve, synchronously driving the box body 56 to descend. During the entire descending process, the bracket 813 always stably supports the supporting seat 824.

[0056] In addition, the pressing belt 57 is heated by the electric heater element 50 to prevent the glue from drying out prematurely and affecting the adhesiveness.

[0057] Furthermore, the positioning mechanism 6 is installed on the workbench 1 through a lifting mechanism 7 , and is driven by the lifting mechanism 7 to achieve synchronous lifting and lowering movements with the dispensing machine 3 and the hot press 5 .

[0058] Example 4 Components identical or corresponding to those in the third embodiment are denoted by the same reference numerals as those in the third embodiment. For simplicity, only the differences from the third embodiment are described below. The fourth embodiment differs from the third embodiment in that: like Figure 12 As shown, this embodiment provides a fully automatic gluing and hemming hot pressing process for clothing fabrics, comprising the following steps: Step 1: When the fabric 100 is transported by the conveying mechanism 2 through the glue dispensing station, the glue dispensing machine 3 simultaneously applies glue continuously and evenly to the glued portion of the fabric to be folded; Step 2: The feeding end of the folding station is located at the front end of the gluing station. After the gluing is completed, the fabric 100 is continuously conveyed backward by the conveying mechanism 2, passes through the folding device 4 in sequence, and forms two folded edges under its guidance; Step 3: After the folding is completed, the fabric 100 is continuously transported backward to the hot pressing channel of the hot pressing station, and the fabric 100 is hot-pressed, bonded and shaped by the hot pressing machine 5 and then automatically output.

[0059] Furthermore, a positioning station is provided at the feed end near the folding station. The auxiliary pressure wheel provided at the positioning station rotates synchronously and passively in the opposite direction with the conveying mechanism 2 and acts on the fabric in a rolling point pressure manner, so that the fabric does not undergo isotropic deformation during the transmission process.

[0060] Furthermore, a cleaning station is provided on one side of the dispensing station, so that when the dispensing station stops working, the dispensing head 30 of the dispensing machine 3 can be moved to the dispensing station to clean it.
