Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.

Referring to fig. 1 to 4, an embodiment of the present invention includes:

a cushion overedger comprises a frame 7, a linear rail 3, a puncture clamping jaw 2, a material lifting frame 4, a working platform 5, an overedger 1 and a control center 6. The frame 7 is formed by section bar concatenation, installs decorative board 8 around frame 7, and work platform 5 installs at the top of frame 7, and one side of work platform 5 is equipped with control center 7. The material lifting frame 4 is located at one end of the linear track 3, and the ground mat is pressed on the working platform 5 by the puncture clamping jaw 2 and slides to the overedger 1 along the linear track 3. The linear track 3 is provided with two puncture clamping jaws 2: a first piercing jaw and a second piercing jaw. The first puncture clamping jaw reciprocates between the material lifting frame 4 and the overedger 1; the second puncture clamping jaw reciprocates between the overedger 1 and the discharge hole. Adopt two puncture clamping jaws to pay-off in turn and get the material, can improve equipment's work efficiency. The lifting frame 4 comprises a supporting plate 41 which can be lifted, and the starting position of the first puncture clamping jaw is positioned right above the supporting plate 9. The material lifting frame 9 is also provided with an expansion plate 42 with the same height as the working platform 5, and the expansion plate 42 is moved to a position between the supporting plate 41 and the initial position of the first puncturing clamping jaw through an air cylinder. When the ground mat lifting device works, ground mat materials are stacked on the supporting plate 41, the supporting plate 9 slowly rises under the action of power lifting, and the material lifting frame 4 is further provided with a third puncturing clamping jaw which is adjacent to the first puncturing clamping jaw. The third piercing jaw picks up the mat on the pallet 41 and raises it to a level above the table top 5 by a vertically lifting pneumatic power. At this time, the retractable plate 42 is pushed out by power, extends to the lower part of the grabbed ground mat, the ground mat is put down by the third clamping jaw, and then the ground mat is clamped by the first clamping jaw and moved to the overedger 1, so that the friction force during conveying is reduced for convenience of conveying, and a plurality of balls 51 are embedded on the surface of the working platform 5. The mat is fed to an overlock machine 1, and the overlock machine 1 performs edge overlock on the edge of the mat.

The hemming device 1 is installed on the frame 7, a sliding rail 10 is arranged at the bottom of the hemming device, the hemming device is conveniently pulled out from the frame 7 through the sliding rail 10, the hemming device can be conveniently operated when needing to be maintained, and meanwhile the frame is further provided with a limit switch to prevent the hemming device from sliding over. The overedger 1 comprises a slow-pushing assisting wheel 11 and a sewing machine 12, the slow-pushing assisting wheel 11 is positioned on one side of the sewing machine 12, the slow-pushing assisting wheel 11 generates a frequency conversion feeding speed which is the same as or opposite to that of the sewing machine, and the second puncture clamping jaw sends the overedged ground mat to a discharge port along a linear track 3. The slow boosting wheel 11 is positioned at one side of a presser foot of the sewing machine 12, and the slow boosting wheel 11 generates a variable frequency feeding speed which is the same as or opposite to that of the sewing machine 12. The slow boosting wheel 11 is driven by a variable frequency motor 19, the feeding direction of the slow boosting wheel 11 is parallel to the feeding direction of the sewing machine 12, and the rotation of the processed ground mat is generated when the feeding direction of the slow boosting wheel 11 is opposite to the feeding direction of the sewing machine 12. When the feeding direction of the slow-pushing auxiliary wheel 11 is consistent with that of the sewing machine 12, linear overedgement can be achieved, and due to the fact that a fillet structure exists on the floor mat, after the linear overedgement in one direction is finished, fillet overedgement is needed. At this time, the slow push wheel 11 generates a feeding speed opposite to the feeding direction of the sewing machine 12, so that the rotation of the slow push wheel 11 with the stitch of the sewing machine as the origin and the radius can be realized. Meanwhile, the size of the rotating fillet of the slow pushing wheel 11 can be adjusted according to different rotating speeds of the slow pushing wheel, so that the fillet with different sizes can be conveniently subjected to overedgement processing. And correlation optical fibers for sensing the rotation of the ground mat in place are further arranged around the head of the sewing machine 12, and the laying direction of the correlation optical fibers is parallel to the feeding direction of the sewing machine 12. The ground mat rotates in place under the action of the slow boosting wheel and covers the correlation optical fiber, and the correlation optical fiber instructs the variable frequency motor to stop reversely rotating. Because the overseam of fillet can't control when rotating next straight flange and stop, so adopt correlation optic fibre, the arranging of correlation optic fibre can be adjusted, adjust according to the ground mat of different specifications, when the ground mat lasts under the effect of slow boost wheel 11 and rotates, the ground mat rotates next straight line overseam position, the ground mat will cover correlation optic fibre, at this moment, correlation optic fibre sends the instruction to control center, control center stops the reverse rotation of slow boost wheel 11, and become the rotation with the sewing machine 12 pay-off syntropy, next straight flange overseam has just so begun.

The aircraft nose department of sewing machine 12 still is equipped with response broken string mechanism, and response broken string mechanism is including leveling tablet 13 and pneumatic scissors 14, levels tablet 13 and is located the syringe needle side of sewing machine 12, and pneumatic scissors 14 is located between the syringe needle of leveling tablet 13 and sewing machine 12, levels tablet 13 and monitors the warpage degree of ground mat. Since the mat warps after being stitched, the edges of the mat that are not stitched are flat. Therefore, when the ground mat is about to be stitched over for one turn, the sewing machine needs to be stopped. The leveling induction plate is slightly higher than the overedged height of the floor mat, and the height of the leveling induction plate is fixed by the warping height of the floor mat in actual processing. After the sewing machine stops overedging, the pneumatic scissors can cut the silk thread, and the ground mat enters the next working procedure.

Because some thread ends exist on the stitched-over ground mat, an ultrasonic thread ironing mechanism is also arranged at the discharge end of the sewing machine 12, and the ultrasonic thread ironing mechanism comprises an ultrasonic generator 15 and a tooth surface thread ironing head 16. The tooth surface thread ironing head 16 is pressed with the ultrasonic generator 15 under the driving of pneumatic power, so that the thread passing between the two is ironed and broken.

The broken line protection mechanism comprises a power-off switch and a line hooking frame, the line hooking frame is pulled up by the silk threads for overedging the floor mat, after the silk threads are disconnected, the line hooking frame rotates to fall and touches the power-off switch, and the power-off switch controls a power supply circuit of the floor mat overedging device. Since the mechanical tension is not equal during the processing, the thread is easy to break during the operation, and if the device is still continuously operated, the processing error is generated. Therefore, the wire-breaking protection mechanism can effectively solve the problem.

The puncture clamping jaw comprises a support 21, a connecting block 22 and two overturning plates 23 arranged in parallel, wherein a plurality of puncture tips 24 are arranged on the bottom surface of the overturning plate 23. Four vertical pillars are arranged on the support 21, a rotating shaft 25 penetrating through the front end face and the rear end face of the turnover plate is arranged on the turnover plate, the two turnover plates 23 are fixed on the pillars of the support in a parallel position relationship of the rotating shaft, and the turnover plates 23 can rotate around the rotating shaft 25. The front end faces of two adjacent sides of the two turnover plates 23 are respectively provided with a raised cylindrical end, and the connecting block 22 is provided with a long slotted hole matched with the cylindrical end. The connecting block connects the two turnover plates 23 through the matching of the long slot hole and the cylindrical end. The connection is also connected with at least one telescopic cylinder 26 which can lead the turnover plate 23 to rotate around the rotating shaft, and the telescopic cylinder 26 is fixed on the support 21. Two returning face plates 23 simultaneously produce relative reverse rotation under telescopic cylinder 26's promotion, when telescopic cylinder 26's piston rod stretches out, two returning face plates 23 are relaxed and expand, and when telescopic cylinder 26's piston rod was withdrawed, the junction of two returning face plates 23 upwards pulled up, and returning face plates 23 rotated around its pivot, and two returning face plates 23 just form the face of pressing from both sides, and the puncture point on returning face plates 23 bottom surface is after pricking into the ground mat, and two returning face plates 23 that press from both sides just can firmly clip the ground mat.
