By adopting the cord fabric conveying, cutting, receiving and taking method, the height difference of the head part of the cut film does not change along with the width of the cord fabric and the cutting angle of the film, the blanking stability when the head part of the film is cut is improved, the precision of splicing feeding is ensured, and the splicing quality is improved.
Description
Technical Field
The invention relates to a tire component manufacturing process, in particular to a cord fabric conveying, cutting, receiving and taking method of a wirecord fabric cutting machine.
Background
The traditional wirecord fabric cutting machine is adopted to cut the film, the leading-out delivery of the cord fabric before cutting takes the central line of the cord fabric as a reference, the leading-out rotating center of the cord fabric is positioned at the intersection position of the central line of the reference and the cutting edge line of the cutter, and the cut film is fixed at the rear end of the taking conveyer belt and the front end swings to avoid the cutter.
Because the front end of the film receiving and conveying belt swings to avoid the cutter, the height difference between the head of the cut film and the film receiving and conveying belt changes along with the width and the cutting angle of the curtain cloth, the head of the curtain cloth film can generate position deviation due to the difference of the height of the knife edge and the film receiving and conveying belt when blanking, the repeated precision of the head of the film conveyed to the splicing part is poor, the joint is easy to misplace, and the splicing quality and the stability are influenced.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a cord fabric conveying, cutting, receiving and fetching method of a wirecord fabric cutting machine, which can improve the stability of the blanking position of the head of a cut film and further improve the splicing quality.
The cord fabric conveying, cutting, receiving and taking method of the wirecord fabric cutting machine can solve the technical problems, and the operating scheme is as follows:
1. before cutting, the curtain fabric is guided to open and delivered by taking the side edge of the curtain fabric close to the splicing device as a reference, and the splicing device is positioned in front of the conveying direction of the film receiving and conveying belt.
2. The opening rotation center (vertical direction) of the curtain cloth is positioned at the intersection position of the reference side edge and the cutting edge line of the cut-off knife.
3. The film receiving and conveying belt adopts a mode that the front end is fixed and the rear end swings to avoid the cutter, and the swinging center (horizontal direction) of the rear end of the film receiving and conveying belt is intersected with the unwinding rotating center.
The invention has the beneficial effects that:
by adopting the curtain cloth conveying, cutting, receiving and taking method of the wirecord fabric cutting machine, the height difference of the head falling point of the cut film (the distance between the cutter edge and the film receiving and taking conveyer belt) does not change along with the width of the curtain cloth and the cutting angle of the film, thereby improving the stability of the blanking when the head of the film is cut, ensuring the precision of splicing feeding and improving the splicing quality.

Detailed Description
The technical solution of the present invention will be further explained with reference to the embodiments shown in the drawings.
The invention relates to a cord fabric conveying, cutting, receiving and taking method of a wirecord fabric cutting machine, which is used for cutting and conveying cord fabrics 1 based on a cord fabric guiding and delivering device 8, a cutting device and a film receiving and delivering device, wherein the film receiving and delivering conveyer belt 5 of the film receiving and delivering device is arranged in the front and back directions, the front end and the back end of the film receiving and conveyer belt 5 are respectively and correspondingly arranged on a front belt roller 9 and a back belt roller 10, and a cutter 4 of the cutting device is arranged on the left side of the film receiving and conveyer belt 5 as shown in figures 1, 2 and 3.
The invention relates to an operation scheme for cutting and conveying a curtain cloth 1, which comprises the following steps:
1. before cutting, the opening delivery of the curtain cloth 1 on the curtain cloth opening delivery device 8 takes the side edge of the curtain cloth 1 close to the splicing device 11 as a reference, and the splicing device 11 is positioned in front of the conveying direction (arrow direction in the figure) of the film receiving and conveying belt 5.
2. The opening rotating center 2 of the cord fabric opening delivery device 8 is arranged at the intersection position of the reference side edge 3 and the cutting edge line of the cutter 4.
3. The film receiving and conveying belt 5 adopts a mode that a front belt roller 9 is fixed, a rear belt roller 10 swings up and down to avoid a cut-off knife 4, and a swing center 6 of the rear belt roller 10 is arranged between the front belt roller 9 and the rear belt roller 10 at the bottom of the film receiving and conveying belt 5 and is intersected with a leading-out rotation center 2.
According to the operation scheme, no matter whether the cutting angle A of the curtain cloth 1 with the same width is changed, the film head 7 of the cut film is always positioned in front of the swing center 6 of the rear belt roller 10, and the film receiving and conveying belt 5 between the swing center 6 and the front belt roller 9 is always positioned on the horizontal plane, so that the distance H between the film head 7 and the film receiving and conveying belt 5 (namely the fall between the film receiving and conveying belt 5 and the knife edge) is unchanged, the position deviation is basically not generated after the film head 7 falls, the repeated precision of conveying the film head 7 to the splicing device 11 is ensured to be high, the joints of the front film and the rear film are not easy to be dislocated, and the splicing quality and the splicing stability are improved.
