[0084] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. Example 1

[0085] like Figure 1 to Figure 16 As shown, the zipper single-folding three-in-one sewing machine of this embodiment includes a frame 1, an assembly position 100 located in the middle of the frame 1, and a first feeding working part 200 for feeding and bending the base material, a second feeding working part 300 for feeding the reflective sheet, and a zipper feeding working part 400 for cutting and feeding the zipper 500, which are respectively arranged on the frame 1 around the assembly position 100; the directions indicated by the XYZ axes in this embodiment are as shown in FIG. Figure 1 As shown, the horizontal direction and the transverse direction include the X-axis and the Y-axis direction, and the longitudinal direction is the Z-axis direction.

[0086] It also includes a clamping displacement device 8 located at one side of the first feeding working part 200 and used to transfer the bent base material to the assembly position 100, and a zipper correction device 6 that can move synchronously with the clamping displacement device 8 along the X-axis direction is provided at the lower part of the clamping displacement device 8; the reflective sheet 600 and the zipper 500 are transferred to the assembly position 100 through the second feeding working part 300 and the zipper feeding working part 400 in turn, and then the bent base material is transferred to the assembly position 100 through the clamping displacement device 8, and at the same time, the clamping displacement device 8 drives the zipper correction device 6 to move synchronously and correct the zipper during the transfer process; that is, the cooperation of the clamping displacement device 8 and the zipper correction device 6 in this embodiment realizes the transfer of the bent base material and the correction operation of the zipper on the assembly position 100;

[0087] Specifically, the zipper correction device 6 includes a zipper correction fixing seat 61 and a zipper correction slide 62 that can slide along the zipper correction fixing seat 61. The zipper correction fixing seat 61 is fixed to the frame 1. The two ends of the zipper correction slide 62 are respectively provided with a zipper correction return column 63 and a zipper correction process column 64 extending upward. When the clamping displacement device 8 moves toward the assembly position 100, it can abut against the zipper correction process column 64 to drive the zipper correction slide 62 to move. When the clamping displacement device 8 is reset, it can abut against the zipper correction return column 63 The zipper correction slider 62 is then driven to move; through the above structure, the zipper correction device 6 can be synchronized with the lateral movement state of the clamping displacement device 8, and the zipper correction fixed seat 61 also includes a zipper correction guide rail 65 located at the lower part of the zipper correction slider 62, and a zipper correction pressure strip 66 located at the upper part of the zipper correction slider 62; the zipper correction slider 62 is limited by the zipper correction guide rail 65 and the zipper correction pressure strip 66, and a space is provided to accommodate the zipper correction slider 62 sliding in the X-axis direction.

[0088] like Fig. 9 and Fig.10 In the zipper structure shown, the bottom of the zipper correction slide 62 is provided with a slide groove corresponding to the protruding part of the zipper, and the top of the zipper correction slide 62 is arranged in an arc shape, so as to facilitate the smooth contact between the zipper correction slide 62 and the fabrics on both sides of the zipper when correcting the deviation. That is, during the reciprocating motion of the zipper correction slide 62, the zipper transferred to the reflective sheet through the zipper displacement device 12 will be straightened to achieve correction, and the folded base material will be placed on the zipper. At this time, the sewing clamping device 16 also clamps the three synchronously for subsequent sewing work. It should be noted that the sewing clamping device 16 clamps the reflective sheet, the zipper that has completed the correction, and the folded base material that is still in the clamping displacement device 8 and transfers them to the flat sewing machine for sewing. In this way, it can be ensured that the zipper transferred to the flat sewing machine will not be offset, and the positional relationship between the zipper, the reflective sheet and the base material can also be guaranteed to be more accurate.

[0089] Regarding the clamping displacement device 8, as Figure 6 As shown, it includes a lateral moving component 8a, a longitudinal moving component 8b and a displacement clamping end 8c. The lateral moving component 8a is used to drive the displacement clamping end 8c to move along the X and Y axis directions, and the longitudinal moving component 8b is used to drive the displacement clamping end 8c to move along the Z axis direction; the displacement clamping end 8c includes an upper clamping plate 8d, a longitudinal adjustment component 8e that can be used to drive the upper clamping plate 8d to move longitudinally, and a lower clamping plate 8f; the upper clamping plate 8d is driven to move longitudinally by the longitudinal adjustment component 8e, so as to cooperate with the lower clamping plate 8f to clamp the bent bottom material, and after the clamping is completed, it is transported to the assembly position 100; at the assembly position 100, the reflective sheet, the zipper and the bottom material are placed in sequence from bottom to top,

[0090] like Figure 3 , Fig.16 As shown, it also includes a sewing clamping device 16 and a sewing discharge part 18, through which the reflective sheet, the zipper after correction, and the base material after bending are clamped and transferred to the sewing discharge part 18 for sewing; regarding the sewing discharge part 18, the sewing discharge part 18 also includes a discharge device 17, a blanking table 20 and a flat sewing machine 21; the discharge device 17 includes a discharge truss 17a, and a discharge suction cup 17b arranged on the discharge truss 17a for adsorbing the sewn material; the discharge truss 17a is driven by a cylinder to move in the horizontal and vertical directions; the blanking table 20 is used to place the sewn material.

[0091] Regarding the zipper feeding working part 400, Figure 12~Figure 14 As shown, the zipper feeding working part 400 includes a zipper displacement device 12, a zipper pulling device 13 and a zipper cutting device 14;

[0092] The zipper pulling device 13 includes a limiting guide clamp 13a and a pulling clamp 13b. The limiting guide clamp 13a guides and limits the zipper, and cooperates with the pulling clamp 13b to pull the zipper of a predetermined length to the zipper displacement device 12. Specifically, the limiting guide clamp 13a can clamp the zipper in the middle of the "convex"-shaped slot, which plays a role in limiting the position of the zipper and guiding it during the pulling process. The zipper of a predetermined length is pulled by setting the stroke of the pulling cylinder corresponding to the pulling clamp 13b, and the zipper is sheared by the zipper cutting device 14 arranged between the zipper displacement device 12 and the limiting guide clamp 13a. The zipper cutting device 14 adopts pneumatic scissors.

[0093] Furthermore, in order to facilitate the cutting of the zipper by the zipper cutting device 14 and the pulling of the zipper by the pulling claw 13b, a pushing and tightening clamp 13c is also provided between the limiting guide clamp 13a and the zipper cutting device 14. Specifically, the pushing and tightening clamp 13c is also provided with a "convex" shaped groove that can clamp the zipper in the middle. The limiting guide clamp 13a and the pushing and tightening clamp 13c both include an upper clamp 13g and a lower clamp 13h. The upper clamp 13g is two clamps arranged opposite to each other, and a "convex" shaped groove is formed in the middle of the two clamps. Both clamps are fixed to the lower clamp 13h through waist-shaped holes, which can achieve the effect of adjusting their positions, thereby achieving better fixation of the zipper.

[0094] The material pushing and tightening clamping plate 13c is shorter than the limiting guide clamping plate 13a, and the material pushing and tightening clamping plate 13c includes a transverse material pushing drive 13d and a longitudinal tightening drive 13e (see Fig.14The dotted line in the middle indicates a partial structure). The smaller volume of the pushing and tightening clamping plate 13c can facilitate its reciprocating motion under the drive of the lateral pushing drive 13d. Through this reciprocating motion, the cut zipper can be pushed a certain distance in the direction of the traction clamping claw 13b. In this way, it is more convenient to clamp the traction clamping claw 13b, and it is also easier to control the predetermined length required for the zipper. The length of the cut zipper is the sum of the distance pushed and the distance pulled by the traction clamping claw 13b. The longitudinal tightening drive 13e can drive the longitudinal device The push rod 13f arranged in the pushing and tightening clamp 13c moves back and forth. The push rod 13f is vertically arranged and can move up and down in the slide groove in the pushing and tightening clamp 13 under the drive of the longitudinal tightening drive 13e. There are two push rods 13f, which are respectively arranged on both sides of the pushing and tightening clamp 13, and can tighten the fabrics on both sides of the zipper. The push rod 13f can be used to tighten and fix the zipper when the zipper cutting device 14 shears the zipper and when the cut zipper is pushed toward the traction clamp 13b.

[0095] The zipper displacement device 12 includes two zipper clamping arms 12a, and a zipper displacement transverse drive 12b for driving the two zipper clamping arms 12a to move transversely toward the assembly position 100; the two zipper clamping arms 12a are respectively arranged at the two ends of the zipper to be cut or at positions close to the two ends, and the zipper of a predetermined length pulled by the pulling clamping claw 13b can be clamped by the two zipper clamping arms 12a; each zipper clamping arm 12a is provided with a zipper displacement longitudinal drive 12c and a displacement clamping claw 12d located at the bottom end of the zipper displacement longitudinal drive 12c, and after the displacement clamping claw 12d clamps the cut zipper, it drives the cut zipper to move longitudinally through the zipper displacement longitudinal drive 12c, and at the same time cooperates with The zipper displacement transverse drive 12b transfers the cut zipper to the assembly position 100. A zipper positioning device 9 is also provided at the bottom of the assembly position 100. The zipper positioning device 9 includes two sets of positioning and clamping arms 9a that are relatively arranged on both sides of the assembly position 100, and can be used to clamp the two ends of the cut zipper. Specifically, the positioning and clamping arm 9a is driven by the clamping arm transverse driving component 9b and the clamping arm vertical driving component 9c. The positioning and clamping arm 9a specifically adopts a bending plate structure. The width of the bending plate is slightly smaller than the width of the raised part in the middle of the zipper, so that it will not affect the sliding of the zipper correction slider 62 to correct the zipper.

[0096] Regarding the first feeding working part 200, the first feeding working part 200 includes a bottom material automatic feeding device 3, a bottom material feeding conveying device 4, a bottom material edge alignment device 5, a bottom material pressing device 7 and a bottom material folding device 19;

[0097] The bottom material automatic feeding device 3 is used to store the bottom material and drive the bottom material to move in the vertical direction. The bottom material feeding conveying device 4 is used to pick up the bottom material and move the bottom material to the position of the bottom material edge alignment device 5. The bottom material edge alignment device 5 is used to perform edge alignment operations on the bottom material before bending.

[0098] The bottom material pressing device 7 is used to press and fix the bottom material to be bent which has been aligned at the bottom material alignment device 5. The pressing cylinder 7a on the bottom material pressing device 7 can drive the corresponding pressing block 7b to move up and down along the Z axis. After being pressed by the pressing block 7b, the bottom material will not move during bending.

[0099] After the bottom material is compacted, the folding cylinder 19a on the bottom material folding device 19 drives the corresponding folding plate 19b to move downward along the Z-axis direction, so that the protruding part of the bottom material can be bent downward. At this time, the bend is about 90°. Then the clamping displacement device 8 is inserted and clamped to make it present a folded state, which is called folding. Because the opposite sides use metal bottom plates, the upper and lower surfaces are relatively smooth. After the clamping displacement device 8 clamps the bottom material, the clamping state of the bottom material can be maintained relatively smoothly to take it out and transport it.

[0100] The bottom material automatic feeding device 3 includes a bottom material lifting worktable 3c, a limit baffle 3a and a limit switch 3b arranged on the bottom material lifting worktable 3c. The limit baffle 3a is provided with a waist-shaped hole for fixing, and the fixed position can be adjusted according to the size of the cloth during installation. The limit baffle 3a is used to limit the bottom material, and the limit switch 3b is used to control the movement height of the bottom material lifting worktable 3c. Specifically, a micro switch is used. When the cloth rises to a certain height, the micro switch will be triggered, and then the corresponding driving device will be directly or indirectly controlled to stop moving through the micro switch; the bottom material lifting worktable 3c is driven by a cylinder;

[0101] The bottom material loading and conveying device 4 includes a material transfer truss 4a and a material transfer suction cup 4b arranged on the material transfer truss 4a for adsorbing the bottom material; the material transfer truss 4a is driven by a cylinder to move in the horizontal and vertical directions; the number of the material transfer suction cup 4b is two or more.

[0102] The bottom material edge alignment device 5 comprises a first pair of edge baffles 5a and a corresponding first pair of edge cylinders capable of driving the first pair of edge baffles 5a to move horizontally along the X-axis direction, and a second pair of edge baffles 5b and a corresponding second pair of edge cylinders capable of driving the second pair of edge baffles 5b to move horizontally along the Y-axis direction; the bottom material is moved to a predetermined position by the cooperation of the first pair of edge baffles 5a and the second pair of edge baffles 5b, and the edge alignment process will control the stroke of the corresponding edge cylinders according to the size of the cloth so as to push the cloth to the preset placement position.

[0103] Regarding the second feeding working part 300, the second feeding working part 300 includes a reflective sheet automatic feeding device 11, a reflective sheet feeding conveying device 10 and a reflective sheet edge alignment device 15; the reflective sheet automatic feeding device 11 is used to store the reflective sheet and drive the reflective sheet to move in the vertical direction, the reflective sheet feeding conveying device 10 is used to pick up the reflective sheet and move the reflective sheet to the position of the reflective sheet edge alignment device 15, and the reflective sheet edge alignment device 15 is used to perform edge alignment operations on the base material;

[0104] The reflective sheet edge alignment device 15 is arranged around the assembly position 100, and the reflective sheet completes the edge alignment operation, that is, the reflective sheet reaches the preset assembly position 100;

[0105] The overall structure and working principle of the second feeding working part 300 are basically the same as the base material automatic feeding device 3, the base material feeding conveying device 4, and the base material alignment device 5 of the first feeding working part 200, that is, the reflective sheet automatic feeding device 11 has the same structure as the base material automatic feeding device 3; the reflective sheet feeding conveying device 10 has the same structure as the base material feeding conveying device 4; and the reflective sheet alignment device 15 has the same structure as the base material alignment device 5.

[0106] The complete working process is as follows: first, prepare the base material, reflective sheet, and zipper, that is, place the base material on the base material automatic feeding device 3, place the reflective sheet on the reflective sheet automatic feeding device 11, and place the zipper on the traction clamp 13b;

[0107] Then the pick-up structure on the reflective sheet feeding and conveying device 10 picks up the reflective sheet, and puts the reflective sheet to the position of the reflective sheet edge alignment device 15 for reflective sheet edge alignment, and waits for further instructions after the edge alignment is completed;
