[0037] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0038] like Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 as well as Figure 6 As shown, in an embodiment of the present invention, a sewing and gluing device for a sewing machine includes a base 1 and a mounting bracket 2, wherein the mounting bracket 2 is fixedly mounted on the base 1;

[0039] The base 1 is fixedly mounted on one end of the sewing machine, and a conveying mechanism 9 for conveying fabrics is mounted on the base 1;

[0040] A glue pressing mechanism is provided on the lower side of the top plate 201 of the mounting bracket 2, and the glue pressing mechanism includes an adsorption roller 12, a sealing arc plate 26, a tensioning roller 11 and a cutting assembly. The adsorption roller 12 is rotatably mounted on the lifting frame 5 through a rotary shaft 1201 at its center. The rotary shaft 1201 is driven to rotate by the power assembly 10. The lifting frame 5 is slidably mounted on the top plate 201 and is driven to rise and fall by the lifting member on the top plate 201. Several groups of negative pressure adsorption ports are provided on the arc side of the adsorption roller 12, and the back side of the rubber strip 4 is adsorbed and fixed by the several groups of negative pressure adsorption ports. The sealing arc plate 26 is fixedly mounted on the lifting frame 5, and the sealing arc plate 26 seals the side of the adsorption roller 12 that does not contact the rubber strip 4. The tensioning roller 11 is rotatably mounted on the lifting frame 2 6 via the rotary shaft 2 at its center. The lifting frame 2 6 is slidably mounted on the top plate 201 and elastically connected to the top plate 201 via a first elastic member. The cutting assembly includes a heating resistance wire 13, and both ends of the heating resistance wire 13 are fixedly connected to one end of two groups of right-angle rods 14 respectively. The other ends of the two groups of right-angle rods 14 are slidably connected in the corresponding driving frames 15 and elastically connected to one end of the driving frames 15 via a second elastic member. The other ends of the two groups of driving frames 15 are fixedly connected to the slewing rings 19 on both sides of the lifting frame 1 5 respectively. The slewing ring 19 is coaxially arranged with the rotary shaft 1 1201 of the adsorption roller 12, and the slewing ring 19 is intermittently meshed with the rotary shaft 1 1201 via a meshing assembly.

[0041] When the rotary ring 19 is engaged with the rotary shaft 1201, the heating resistance wire 13 drives the rubber strip 4 on the adsorption roller 12 through the transmission member to cut. When the rotary ring 19 is disengaged from the rotary shaft 1201, the driving frame 15 is reset through the reset member and drives the heating resistance wire 13 to disengage from the rubber strip 4.

[0042] When in use, the cloth 3 is evenly conveyed by the conveying mechanism 9, and the adhesive strip 4 for adhesion is conveyed through the guide of the tensioning roller 11 and is arranged on the outer side of the adsorption roller 12. The conveyed adhesive strip is straightened by the tensioning roller 11 to prevent the adhesive strip 4 from becoming loose. At the same time, a number of negative pressure adsorption ports on the end face of the adsorption roller 12 are adsorbed on the back side of the adhesive strip 4, so that the adhesive strip 4 is always fixed during the rotation of the adsorption roller 12. When the adhesive strip 4 is adhered, the lifting frame 5 can be driven down by the telescopic member to adhere the adhesive strip 4 to one side of the cloth 3. The orderly adhesion of the adhesive strip 4 is achieved by the coordinated rotation of the adsorption roller 12 and the conveying mechanism 9.

[0043] At the same time, when the rubber sleeve needs to be cut, the rotating ring 19 can be meshed with the rotating shaft 1201 through the meshing component. At this time, the rotation angular velocity of the rotating ring 19 is consistent with the rotation angular velocity of the rotating shaft 1201, so that the heating resistance wire 13 at the end of the driving frame 15 is not offset relative to the cutting position of the rubber strip 4. When the heating resistance wire 13 is close to the rubber strip 4 to achieve cutting, it moves along the mirror direction of the end face of the adsorption roller 12, avoiding the heating resistance wire 13 and the cutting position from being offset during the cutting process. After the cutting is completed, the heating resistance wire 13 is disengaged by the meshing gear disc 17 and the meshing gear disc 2 18, so that the rotating ring 19 is disengaged from the rotating shaft 1201, and the reset component drives the heating resistance wire 13 to disengage from the rubber strip 4 and reset it to the initial position.

[0044] like Figure 2 As shown, in the embodiment of the present invention, the conveying mechanism 9 includes a feed roller 901 group, a rubber pressing wheel group and a support platform, the feed roller 901 group includes two groups of feed rollers 901, the two groups of feed rollers 901 are rotatably mounted on the mounting plate 1 on one side of the base 1, and a channel for conveying the cloth 3 is provided between the feed rollers 901.

The support roller 902 is rotatably connected to the mounting plate 2 on the other side of the base 1. The two ends of the rubber pressing roller 903 are rotatably connected to the sliding block 904 on the upper side of the mounting plate 2, and the sliding block 904 is connected by a third spring 9 05 is elastically connected to the bottom plate of the mounting plate 2, wherein the support roller 902 is connected to a group of feed rollers 901 through a first transmission belt 906. The gear assembly in the present invention includes two groups of meshing gears, which are meshed and driven by the two groups of meshing gears, and the two groups of feed rollers 901 are driven by the second motor 101 to rotate in a mirror image. In addition, the present invention elastically installs a glue pressing roller 903 on one side of the support roller 902, and the glue pressing roller 903 presses and fixes the rubber strip 4 adhered to the cloth 3 to maintain the adhesion stability of the rubber strip 4.

When the rubber strip 4 is cut by the cutting component, the telescopic air can be contracted to drive the adsorption roller 12 away from the cloth 3 to avoid the rubber strip 4 at the bottom of the adsorption roller 12 accidentally contacting the cloth 3 and causing adhesion. The telescopic cylinder 7 used to drive the lifting frame 5 to lift can also be replaced by a component with telescopic driving capability. The present invention does not have a rigid requirement for the telescopic member.

[0046] Furthermore, the power assembly 10 includes a first motor 907 and a second transmission belt 102. The first motor 907 is fixedly mounted on a side panel of the lifting frame 5, and its output shaft is connected to one end of the rotating shaft 1201 through the second transmission belt 102. When the first motor 907 is turned on, its output shaft synchronously drives the rotating shaft 1201 to rotate, ensuring that the adsorption roller 12 increases the conveying speed of the cloth 3 and realizes the feeding and adhesion of the rubber strip 4.

[0047] Furthermore, the first elastic member is a first spring 8, and one end of multiple groups of the first springs 8 is fixedly connected to the top plate 201 of the lifting frame 2 6, and the other end is fixedly connected to the top plate 201 of the mounting bracket 2. In the present invention, when the lifting frame 1 5 is raised or lowered, the vertical position of the tensioning roller 11 is adjusted by the corresponding expansion and contraction of the first spring 8, so that the rubber strip 4 is always kept in a tensioned state.

[0048] like Figures 4 to 8 As shown, in the embodiment of the present invention, the meshing assembly includes a meshing toothed disc 17, a meshing toothed disc 2 18 and a telescopic rod 20, the meshing toothed disc 17 is coaxially fixedly installed on one side of the rotating shaft 1201, the meshing toothed disc 2 18 is slidably installed in a limiting hole opened in the center of the rotating ring 19, and a movable disc 23 is elastically installed on the side away from the meshing toothed disc 17, and the other side of the movable disc 23 is rotatably connected to the telescopic shaft of the telescopic rod 20, and the rod body of the telescopic rod 20 It is fixedly mounted on the corresponding side plate of the lifting frame 1 5 through the mounting seat. In the present invention, when the rubber strip 4 needs to be cut, the telescopic rod 20 is extended to drive the movable disk 23 and the meshing gear disk 2 18 to move toward the meshing gear disk 1 17, and the meshing gear disk 1 17 and the meshing gear disk 2 18 are meshed, so that the rotary shaft 1201 and the rotary ring 19 rotate coaxially, and drive the driving frame 15 and the heating resistance wire 13 at the end of the driving frame 15 to rotate synchronously around the adsorption roller 12;

[0049] And the transmission member is an elastic rope 21, one end of the elastic rope 21 is fixedly connected to one end of the right-angle rod 14, and the other end thereof passes through the guide hole on the side of the driving frame 15 and is fixedly connected to the side of the movable disk 23. When the telescopic rod 20 is extended to drive the meshing connection between the meshing gear disk 17 and the meshing gear disk 2 18, the telescopic rod 20 is further extended, squeezing the movable disk 23 to move in the direction of the meshing gear disk 2 18, and driving the end of the elastic rope 21 to move, and the elastic rope 21 pulls the right-angle rod 14, driving the heating resistance wire 13 to approach the rubber strip 4, and pressing the rubber strip 4 The cutting is carried out. At the same time, after the cutting is completed, the telescopic rod 20 is retracted. At this time, the movable disk 23 elastically mounted in the meshing toothed disk 2 18 by the fourth spring 24 moves away synchronously with the end of the telescopic rod 20. At this time, the end of the elastic rope 21 is reset, and the right-angle rod 14 is reset to the end of the driving frame 15 under the elastic force of the second elastic member, and drives the heating resistance wire 13 and the adsorption roller 12 to move away.
