Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0032] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0033] Please refer to the following: Figures 1 to 7 The seamless bonding mechanism and sewing machine provided in the embodiments of this application will now be described.

[0034] refer to Figures 1 to 7 The seamless bonding mechanism proposed in the first aspect of this application is used to be assembled on a sewing machine. It includes a support component and a connecting component 700, wherein the aforementioned support component and rolling component 400 can both be connected to a heating device 600 to achieve heating.

[0035] The sewing machine (not shown in the figure) proposed in the second aspect of this application includes: a frame, a control module, and the aforementioned seamless bonding mechanism.

[0036] The support assembly is used to be assembled and connected to the sewing machine, and includes a support frame 110, a heat-conducting block 120 disposed on the top of the support frame 110, a drive device 210 disposed on the support frame 110, and a first conveyor belt mechanism 220 disposed on the support frame 110.

[0037] Specifically, refer to Figures 1 to 3 The heat-conducting block 120 is heat-conducting and is made of a heat-conducting material, such as copper or other metal materials that are heat-conducting and have good rigidity. The support frame 110 has a roughly L-shaped cantilever structure, and its bottom is embedded in the sewing machine table. The heat-conducting block 120 is assembled on the cantilever section of the support frame 110. At the same time, the portion of the cantilever section of the support frame 110 near the column section is inclined, with the inclination direction facing the sewing machine table surface.

[0038] The first conveyor belt mechanism 220 is mounted on the support frame 110 and driven by the drive device 210. The drive device 210 includes a drive motor fixedly mounted on the bottom of the support frame 110; the first conveyor belt mechanism 220 includes a plurality of friction wheels 221 rotatably mounted on the support frame 110 and a first conveyor belt (not shown in the figure) wound around each friction wheel 221; the drive motor is used to drive one of the friction wheels 221 to rotate so that the first conveyor belt can rotate, thereby realizing the conveying of the fabric.

[0039] It should be understood that the heat-conducting block 120 is disposed on the support frame 110 and is located entirely within the annular inner side of the first conveyor belt. The length direction of the heat-conducting block 120 is parallel to the conveying direction of the first conveyor belt, and at least a portion of the first conveyor belt abuts against the top surface of the heat-conducting block 120, or different sections of the first conveyor belt simultaneously abut against both the top and bottom surfaces of the heat-conducting block 120. By arranging the first conveyor belt and the heat-conducting block 120 in this way, when the heat-conducting block 120 is heated to a certain temperature, the heat from the heat-conducting block 120 can be transferred more directly to the first conveyor belt, thereby achieving high-efficiency preheating of the first conveyor belt.

[0040] Further reference Figures 1 to 3 and Figure 6 A heat insulation plate 300 is also provided on the support frame 110. Multiple heat insulation plates 300 are provided, respectively located on both sides and the top of the heat-conducting block 120 on the support frame 110. The heat insulation plate 300 on the top of the heat-conducting block 120 is spaced apart from the end of the heat-conducting block 120 away from the sewing machine table; that is, a section of the top of the first conveyor belt is not covered by the heat insulation plate 300. In some embodiments, the heat insulation plate 300 is made of fiberglass.

[0041] By setting up the heat insulation plate 300, especially the heat insulation plate 300 on the top of the support frame 110, on the one hand, when the operator pushes the two sections of fabric side by side forward, the heat insulation plate 300 can isolate most of the heat transferred by the heat-conducting block 120 to the first conveyor belt, thereby avoiding the risk of the operator being burned. On the other hand, since the heat-conducting block 120 is covered with the heat insulation plate 300 on its sides and top, the section of the heat-conducting block 120 that transfers heat to the first conveyor belt can be made as long as possible, so that the first conveyor belt can be fully preheated before conveying the fabric to the hot pressing section, thereby improving the hot pressing effect.

[0042] refer to Figures 1 to 2 The connecting member 700 is mounted on the sewing machine and located above the supporting component. A rolling assembly 400 is provided on the side of the connecting member 700 near the supporting component. The rolling assembly 400 can be movably mounted on the connecting member 700 to be close to or away from the conveying plane of the first conveyor belt, or it can be fixedly mounted with a certain gap from the conveying plane of the first conveyor belt. Furthermore, the rolling assembly 400 is positioned directly opposite the section of the heat-conducting block 120 that is not covered by the heat insulation plate 300.

[0043] refer to Figures 1 to 2When the rolling assembly 400 is movable relative to the supporting assembly, the connecting member 700 includes a lateral drive device 710 and a longitudinal drive device 720. The lateral drive device 710 is used to drive the rolling assembly 400 to move so that it can be aligned with or offset from the supporting assembly; the longitudinal drive device 720 is used to drive the rolling assembly 400 closer to or further away from the supporting assembly. Both the lateral drive device 710 and the longitudinal drive device 720 include cylinders and slide rail assemblies. It should be understood that the connecting member 700 shown in the figure is an intentional structure.

[0044] Specifically, the transverse drive device 710 includes a first cylinder 711, a first slide rail 712, and a first slider 713. The first cylinder 711 and the first slide rail 712 are both fixedly mounted on the sewing machine in the transverse direction, and the first slider 713 is slidably mounted on the first slide rail 712 and connected to the piston of the first cylinder 711.

[0045] The longitudinal drive device 720 includes a slide 721, a second cylinder 722, a second slide rail 723, and a second slider 724. The slide 721 is fixedly connected to the first slider 724. The second cylinder 722 and the second slide rail 723 are fixedly mounted on the slide 721 along the longitudinal direction. The second slider 724 is slidably mounted on the second slide rail 723 and connected to the piston of the second cylinder 722. The rolling assembly 400 is connected to the second slider 724.

[0046] Understandably, the rolling assembly 400 can be configured in multiple ways.

[0049] It is understood that both the heat-conducting block 120 and the rolling assembly 400 can be connected to the heating device 600. The heating device 600 can also be implemented in various ways, as detailed below.

[0050] In a first embodiment of the heating device 600, the heating device 600 is respectively disposed in the heat-conducting block 120 and the rolling assembly 400, specifically, heating rods can be inserted into both the heat-conducting block 120 and the rolling assembly 400 to achieve heating. Specifically, in the first embodiment of the aforementioned rolling assembly 400, heating rods are embedded inside each roller, or the rolling assembly 400 is provided with a mechanism that can continuously blow hot air onto the rollers; while in the second embodiment of the aforementioned rolling assembly 400, heating rods are inserted into the rolling frame 410.

[0051] refer to Figures 3 to 5 In a second embodiment of the heating device 600, the heating device 600 is externally mounted on the sewing machine or the connecting member 700, and can supply hot air to the heat-conducting block 120 and the rolling assembly 400 respectively. Specifically, for the heat-conducting block 120, a first channel 121 is provided in the heat-conducting block 120, and the first channel 121 is connected to the heating device 600 through a hot air duct; for the rolling assembly 400, in the second embodiment of the rolling assembly 400, a second channel 411 is provided in the rolling frame 410, and the second channel 411 is also connected to the heating device 600 through a hot air duct.

[0052] It is understood that in the second embodiment of the aforementioned heating device 600, the heating device 600 includes a heating block, a heating tube is inserted in the heating block, and a fourth channel is arranged around the heating tube in the heating block. One end of the fourth channel is connected to the first channel 121 and the second channel 411 respectively through a blower hose, and the other end of the third channel is connected to an external blower.

[0053] refer to Figure 6 In some embodiments, cooling channels are provided in the heat insulation plate 300 covering the top of the heat-conducting block 120. It is understood that the cooling channels can be directly formed in the heat insulation plate 300, or they can be detachably provided in the heat insulation plate 300. Furthermore, in addition to the cooling channels provided in the heat insulation plate 300 covering the top of the heat-conducting block 120, cooling channels can also be selectively provided in the heat insulation plates 300 on both sides of the heat-conducting block 120.

[0054] Specifically, in the embodiment where a cooling channel is detachably provided in the heat insulation plate 300, an installation groove 310 is provided on one side of the heat insulation plate 300 facing the top of the heat-conducting block 120. The installation groove 310 is U-shaped in the heat insulation plate 300, and a cooling pipe (not shown in the figure) is embedded in the installation groove 310. The cooling pipe can be made of a heat-conducting metal material (e.g., copper), and both ends of the cooling pipe are connected to external heat exchange equipment, such as a refrigeration unit.

[0055] refer to Figures 1 to 2In some embodiments, a blower 500 is provided on the connecting member 700 on the side of the rolling assembly 400 near the heat insulation plate 300. The blower 500 is connected to the heating device 600 to supply hot air to the gap between the rolling assembly 400 and the first conveyor belt, so that the top surface of the fabric can be preheated before contacting the rolling assembly 400, thereby improving the connection effect.

[0056] It is understood that the blower 500 can be connected to the same heating device 600 as the aforementioned heat-conducting block 120 and rolling assembly 400, or it can be connected to a separate heating device 600. The heating device 600 connected to the blower 500 includes a heating block, in which a heating tube is inserted. A third channel is arranged around the heating tube in the heating block, with one end of the third channel opening to the blower 500 via a flexible air supply hose, and the other end opening to an external air supply device.

[0057] For more specific details, please refer to Figure 7 The heating block includes a main body 610 and cover plates (not shown) covering opposite sides of the main body 610 in the height direction. Assembly grooves 611 are symmetrically formed on opposite sides of the main body 610 in the height direction, with the depth of the assembly grooves 611 matching the thickness of the cover plates. Several air guide grooves 612 are arrayed at the bottom of each assembly groove 611, and two vent holes 613 are formed at the bottom of each air guide groove 612, penetrating the main body 610. The two air guide grooves 612 on opposite sides of the main body 610 are connected through the same vent hole 613 in a projection direction parallel to the height direction of the main body 610. After the cover plates are placed in the assembly grooves 611, each air guide groove 612 and each vent hole 613 forms a U-shaped, reciprocating third channel 614 within the main body 610. This arrangement of the third channel 614 maximizes its distance within the heating block, improving the gas heating effect.
