The locking shaft 510 is inserted between the first side arm 521 and the second side arm 522, and when the locking bolt 530 is tightened, the first side arm 521 and the second side arm 522 progressively lock the shaft 510.
The carpet 700 is wound around the first tension roller 410 and the second tension roller 420 before being clamped between the driving roller 210 and the pressing roller 230, so that the driving roller 210 drives the carpet 700 to move, and the first tension roller 410 and the second tension roller 420 tension the carpet 700 in the length direction of the carpet 700. When tensioning different carpets 700, the locking bolt 530 may be loosened, and then the locking shaft 510 may be rotated to adjust the positions of the first tensioning roller 410 and the second tensioning roller 420, so as to adjust the degree of tensioning of the carpet 700, and reduce the probability of the carpet 700 being torn while the carpet 700 is tensioned normally.
Referring to fig. 3 and 4, the heating roller 110 is fixedly coupled to the frame 100 by bolts, and the heating roller 110 is disposed between the driving roller 210 and the second tension roller 420. A transition roller 120 is further disposed between the heating roller 110 and the second tension roller 420, and the transition roller 120 is rotatably connected to the frame 100. The carpet 700 is wound around the first tension roller 410 and the second tension roller 420, then wound around the transition roller 120, then wound around the heating roller 110, and finally clamped between the driving roller 210 and the pressure roller 230. When the carpet 700 is wound around the heating roller 110, the rubber layer 720 of the carpet 700 is in contact with the outer circumferential surface of the heating roller 110.
When the carpet 700 is scalded, the heating roller 110 heats itself, one end of the fiber yarn passing through the base fabric is heated and melted by the heating roller 110, and the melted fiber yarn is smoothed on the glue layer 720 under the action of its own tension. As the driving roller 210 rotates, the carpet 700 moves continuously, and the heating roller 110 continuously heats the fiber filaments at different positions and continuously screeds the melted fiber filaments on the glue layer 720. In order to reduce the probability that the melted fiber yarns are adhered to the heating roller 110, a layer of coated paper 111 is laid on the outer circumferential surface of the heating roller 110, the melted fiber yarns are not easily adhered to the coated paper 111, and after the melted fiber yarns are melted and adhered to the coated paper 111, the melted fiber yarns can be wiped off the coated paper 111 by wiping the coated paper 111, so that the service life of the heating roller 110 is prolonged.
Referring to fig. 3 and 4, the frame 100 is further provided with a lifting mechanism 600 for lifting the carpet 700, the lifting mechanism 600 includes a second cylinder 610, a lifting frame 620 and a lifting roller 630, a cylinder body of the second cylinder is fixedly connected to the frame 100 through a bolt, an axis of the second cylinder 610 is perpendicular to an axis of the heating roller 110, and the lifting frame 620 is fixedly connected to a piston rod of the second cylinder 610 through a bolt. The lifting roller 630 is hinged on the lifting frame 620, the axis of the lifting roller 630 is parallel to the axis of the heating roller 110, and the hinged axis of the lifting roller 630 and the lifting frame 620 is perpendicular to the axis of the lifting roller 630.
When the carpet 700 is heated, the lifting roller 630 does not contact the carpet 700, and the adhesive surface of the carpet 700 is pressed against the heating roller 110. When the bottom-burning process cannot be continued due to external factors, the piston rod extending out of the second cylinder 610 causes the lifting roller 630 to contact the carpet 700, and the carpet 700 is no longer in contact with the heating roller 110 under the lifting action of the lifting roller 630, so that the probability that the residual temperature of the heating roller 110 continues to heat the adhesive layer 720, the base fabric layer 710 and the tufting layer 730 is reduced, the probability that the adhesive layer 720, the base fabric layer 710 and the tufting layer 730 are heated and carbonized is reduced, and the yield of the carpet 700 is improved.
The implementation principle of the tufted carpet processing technology in the embodiment of the application is as follows:
firstly, executing the step of manufacturing the base fabric, namely needling the non-woven fibers into the base fabric through a needle machine so as to form a base fabric layer 710;
then, performing a gluing step, namely, coating glue on one surface of the base fabric layer 710 to form a glue layer 720 on one surface of the base fabric layer 710; the adhesive layer 720 enhances the strength of the base fabric layer 710, so that the base fabric layer 710 is not easy to loosen due to pulling;
then, tufting is performed, wherein fiber yarns are implanted into the base fabric layer 710 through a tufting machine, when the fiber yarns are implanted into the base fabric layer 710, the fiber yarns penetrate into the base fabric layer 710 from one side, away from the glue layer 720, of the base fabric layer 710, then the fiber yarns penetrate out from one side, away from the base fabric layer 710, of the glue layer 720, loop wool 731 is formed on one side, away from the glue layer 720, of the base fabric layer 710, and the loop wool 731 formed on the base fabric layer 710 forms a tufting layer 730;
then, a step of ironing the base is executed, wherein one surface of the glue layer 720, which is far away from the base cloth layer 710, is heated through a base ironing machine, so that the fiber filaments penetrating through the base cloth layer 710 are melted;
then, a step of troweling is carried out, and the melted fiber yarns are trowelled on the adhesive layer 720; because the adhesive layer 720 enhances the hardness of the base fabric layer 710, the fiber filaments passing through the adhesive layer 720 are not easy to fall off from the base fabric layer 710 after being melted and smoothed on the adhesive layer 720;
then, a cooling step is carried out, so that the melted and smoothed fiber filaments are cooled and solidified, the fiber filaments are enabled to form strength again, and the probability of falling off of the fiber filaments from the base cloth layer 710 is reduced;
finally, a step of attaching PVC is carried out, PVC is coated on one end face, far away from the base plate layer, of the glue layer 720 to form a PVC layer 740, the PVC layer 740 and the glue layer 720 sandwich the melted and smoothed fiber yarns, the PVC layer 740 is used for fixing the base cloth layer 710, the strength of the base cloth layer 710 is further improved, the base cloth layer 710 is not prone to loosening due to pulling, the PVC layer 740 is used for protecting the fiber yarns penetrating through the base cloth layer 710, the fiber yarns are not prone to abrasion, and the probability that the fiber yarns fall off from the base cloth layer 710 is reduced; because the cellosilk is screeded on glue layer 720, the length of cellosilk after passing through base cloth layer 710 has been shortened, so make the thickness of PVC layer 740 can reduce correspondingly, practiced thrift the raw materials.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
