In order to avoid the loosening and breaking of the fabric edge, usually, the inlet of the sewing machine is equipped with a hemming device to form a hemming machine, and the folded state of the fabric is hemmed.

[0003] At present, most of the guiding and hemming production devices for hemming machines are metal sheets bent inward. The fabric is folded by passing the fabric edge through the metal sheet, and then the hemming of the fabric is completed by moving it towards the hemming machine.

[0004] This kind of guiding and hemming device can only be used for fabrics that are easy to fold. When processing fabrics with a smooth surface and not easy to fold, the fabric is extremely easy to slide off the metal sheet, resulting in the deviation of the folded fabric and affecting the subsequent hemming process. For the above reasons, it is necessary to design a guiding and hemming device that can hem fabrics with a smooth surface and not easy to fold and avoid the deviation of the folded fabric.

[0024] In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following further describes the embodiments of the present disclosure in a clearer and more detailed manner with reference to the accompanying drawings of the present embodiment. Note: The described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0025] The present utility model provides a guiding and hemming device that can perform hot pressing and positioning on soft fabrics, enabling it to be more efficiently applied in a sewing machine, increasing the neatness of the hemmed fabrics, and avoiding the slipping and deviation of the fabrics, as Figure 1 and 2As shown, the guide folding device for the hemming machine includes a hemming machine body 1 and a folding plate 23, an operating table 21 is arranged on the hemming machine body 1, the folding plate 23 is arranged on the operating table 21 through a bonding plate 22, a support seat 3 is arranged on the bonding plate 22, a top plate 4 opposite to the folding plate 23 is slidably arranged on the upper side of the support seat 3, so that the top plate 4 can limit the edge of the folded fabric, and a driving structure 5 is arranged at the bottom of the bonding plate 22, and a hot pressing component 6 penetrating the bonding plate 22 is arranged on the top of the driving structure 5 for hot pressing positioning of the folded fabric. Among them, the laminating plate 22 is aligned with the machine needle of the hemming machine body 1, and the laminating plate 22 is embedded in the operating table 21. The edge of the fabric can be folded through the folding plate 23, and the top plate 4 limits the folded fabric to prevent the fabric from being offset or sliding off the folding plate 23. With the drive of the fabric and the hemming machine body 1, the folded fabric can be driven toward the hemming machine body 1, and the reciprocating drive of the driving structure 5 under the laminating plate 22 can drive the hot pressing component 6 to squeeze the bottom of the fabric. The high-temperature hot pressing component 6 can not only iron the folded fabric, but also intermittently position the edge of the fabric to complete the limitation between double-layer or multi-layer fabrics; finally, with the operation of the machine needle, the locking operation is realized.

[0026] In order to better limit the folding of the edge of the fabric, in some embodiments, the structure of the support seat 3 and the top plate 4 will be further improved, such as Figure 3 As shown, the support seat 3 and the folding plate 23 are arranged parallel to each other, and a slide groove 31 is provided on the support seat 3 so that the top plate 4 can be extended and retracted on the support seat 3 to adjust the distance between the top plate 4 and the folding plate 23, so as to facilitate the insertion and use of fabrics of different thicknesses and facilitate the folding device to process different fabrics.

[0027] In order to better facilitate the folding of fabrics, such as Figure 3 As shown, in some embodiments, the top plate 4 can be set to a T-shaped hook structure, and both ends of the same side of the top plate 4 are provided with inwardly gathered chamfered corners. The chamfered corners of the top plate 4 facilitate the fabric to penetrate the top plate 4 and the hemming plate 23, and the middle part of the two chamfered corners can be used to support the fabric, complete the folding limit of the fabric, and increase the convenience of folding the fabric; the use of the T-shaped top plate 4 facilitates the transitional extrusion of the fabric and provides convenience for pushing the seam edge of the fabric.

[0028] In order to better limit the position of the fabric on the top plate 4, the top plate 4 is elastically connected to the support seat 3, such as Figure 3As shown, in some embodiments, the top plate 4 and the support base 3 are fixedly connected by the same spring 41. A slide bar 42 is disposed through the middle of the spring 41. One end of the slide bar 42 is fixedly connected to the spring 41 and the top plate 4, and the other end of the slide bar 42 is slidably disposed in the support base 3, so that the support base 3 limits and supports the position of the slide bar 42, facilitating the elastic abutment of the top plate 4 between the support base 3 and the hemming plate 23.

[0029] It should be noted that, as Figure 4 shown, in some embodiments, an electrical device with a telescopic function can be used to adjust the position of the hot pressing assembly 6 up and down. In this embodiment, an electric push rod 51 can be used as the driving electrical appliance, and the electric push rod 51 is connected through the fitting plate 22. A box body fixedly connected to the fitting plate 22 is fixedly provided at the lower end of the electric push rod 51, and the box body is located in the operating table 21. By the intermittent reciprocating lifting of the electric push rod 51, the hot pressing assembly 6 can be intermittently pressed against the upper side material to position the folded fabric, increasing the automation of the positioning process of the folded fabric.

[0030] In order to better fold the fabric and position the folded fabric, as Figure 5 shown, a heat conducting plate 61 is provided on one side of the hot pressing assembly 6 close to the hemming plate 23. An electric heating ring 62 is disposed in the heat conducting plate 61. The outside of the electric heating ring 62 is connected to a power supply. Through the energization of the electric heating ring 62 by the power supply, the electric heating ring 62 converts electrical energy into heat energy and transfers the heat to the heat conducting plate 61, facilitating the ironing of the folded fabric by the heat conducting plate 61 to make the fabric smoother, and can also perform indentation treatment on the folded fabric to prevent the fabric from slipping or shifting. Moreover, a plurality of protrusions 63 are provided on the upper side of the heat conducting plate 61. Through the extrusion of the plurality of protrusions 63 against the fabric, the multi-layer fabric at the hem can be locked, increasing the versatility and functionality of the hem production, preventing looseness between the fabrics, and improving the hemming effect of the hemming device.

[0031] Working principle: When the guiding and hemming device is used on a sewing machine, the box body at the bottom of the fitting plate 22 will first penetrate through the operating table 21 and then be flatly installed on the upper side of the operating table 21; then, the electric push rod 51 and the electric heating ring 62 are connected to the power supply. By applying the existing electrical control structures of the electric push rod 51 and electric heating, the telescopic distance and reciprocating telescopic interval of the electric push rod 51 are preferentially set, and the operating temperature of the electric heating ring 62 is set; then the fabric to be processed is placed flat on the operating table 21. The fabric is bent above the hot pressing assembly 6 by passing the sewing edge end of the fabric through the hemming plate 23 and the top plate 4; then, the operator pushes the end of the fabric towards the sewing machine main body 1, so that the top plate 4 limits the fabric. The electric push rod 51 drives the hot pressing assembly 6 to intermittently squeeze the upper fabric, so that the heat conducting plate 61 irons the fabric, and multiple bumps 63 limit the multiple layers of fabric on the upper side, realizing the connection of multiple layers of fabric, facilitating the edge locking process of the fabric moving towards the sewing needle, and avoiding the loosening of the fabric; and the setting of the chamfered parts at both ends of the top plate 4 facilitates the limiting of the fabric between the top plate 4 and the hemming plate 23, avoiding the deviation of the fabric and improving the processing quality of the hemming device.

[0032] Certainly, the above description is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of the present invention.
