Description

Technical Field

[0001] The invention relates to the technical field of textile equipment, and in particular to a double-layer cloth quick docking device and method for cut pile. Background Art

[0002] Flat velvet is made of a double-layer velvet roll woven with pile tissue, and then cut into two after the pile is cut. The surface has dense, flat, erect and shiny velvet. In order to ensure the continuity of the cutting process, the front and rear double-layer velvet rolls need to be docked. Usually, when the cutting of the previous double-layer velvet roll is nearing the end, 5-8m of surplus is reserved and neatly stacked on the ground for docking with the next double-layer velvet roll. This method has the following defects: The double-layer velvet fabric left over is prone to form double-layer folds when it is connected to the next double-layer velvet fabric roll. Due to the characteristics of flat velvet fabric, as long as there are folds, the finished product will have problems. Each velvet roll has a 5-8m margin at the end for docking, and each velvet roll is 50m long, so 14% of the fabric is degraded, resulting in large losses and high costs. Conventionally, two docking methods are used: sewing machine seam docking and manual tape bonding. If sewing machine seam docking is used, the tail of the previous double-layer velvet roll and the head of the next double-layer velvet roll need to be processed into 5cm upper and lower single-layer grey fabrics, and then the upper and lower single-layer grey fabrics need to be sewn separately, which is time-consuming and labor-intensive. If manual tape bonding is used, the docking joint is not firmly glued and is easy to fall off in the velvet cutting machine, affecting the efficiency of velvet cutting. Summary of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a double-layer cloth quick docking device and method for cut pile, which solves the problem of wrinkle marks, saves costs, improves production efficiency, and increases the first-class product rate.

[0004] The object of the present invention is achieved in that: A double-layer cloth quick docking device for pile cutting comprises a pile cloth rack, a docking mechanism, an anti-wrinkle cloth storage mechanism and a pile cutting machine, the pile cloth roll is arranged on the pile cloth rack, the docking mechanism is fixed on the front side of the anti-wrinkle cloth storage mechanism, the docking mechanism comprises lifting cylinders arranged up and down, each lifting cylinder is connected to an electric heating plate, the pile cloth passes through between two electric heating plates, the anti-wrinkle cloth storage mechanism comprises an installation box arranged symmetrically on the left and right, each installation box is provided with a movable guide roller connecting seat which can be lifted and lowered, two movable guide roller connecting seats are connected to the movable guide rollers, the pile cloth entering the anti-wrinkle cloth storage mechanism passes through the inlet guide roller, the movable guide roller and the outlet guide roller and then enters the pile cutting machine.

[0005] Preferably, each installation box is further provided with a chain and a sprocket, wherein the chain is wound between the upper and lower sprockets, and the chain is provided with a notch, and the notch of the chain is connected to a seat through a movable guide roller to form a closed ring.

[0006] Preferably, a servo drive motor is installed in one of the installation boxes, and the servo drive motor drives the sprocket on the corresponding side to rotate.

[0007] Preferably, both ends of the movable guide roller are extended into the corresponding installation box and then connected to the movable guide roller connecting seat, and the installation box is provided with a vertical slide groove corresponding to the movable guide roller.

[0008] Preferably, the docking mechanism is further provided with a hanging rod, and an adhesive tape is hung on the hanging rod.

[0009] Preferably, the height positions of the inlet guide roller and the outlet guide roller are fixed.

[0010] Preferably, an upper travel limit switch and a lower forming limit switch are provided in the installation box corresponding to the movable guide roller.

[0011] A method for quickly butting double-layer cloth for cut pile, using the butt-jointing device, comprises the following steps: Step 1: When the unwinding of the previous double-layer flannel roll is nearing the end, there are 8-10m of cloth left in the roll. Press the start button of the anti-wrinkle cloth storage mechanism, and the servo drive motor drives the movable guide roller to rise, driving the double-layer flannel to arch upward. The movable guide roller stores 4-5m of cloth in front and behind. The tail of the double-layer flannel roll stays on the docking mechanism, and the lifting cylinder on the lower side rises. The lower electric heating plate on which the lower layer of tape is pre-laid rises to serve as a cloth receiving table. Step 2: The last double-layer flannel roll is in place, and the cloth head of the double-layer flannel roll is pulled onto the electric heating plate at the lower side, and the lower surfaces of the cloth head and cloth tail are butted together by the lower layer of adhesive tape, and then the upper layer of adhesive tape is laid, and the upper surfaces of the cloth head and cloth tail are butted together by the upper layer of adhesive tape; Step 3: The upper lifting cylinder descends, driving the upper electric heating plate to press down the joint. The upper and lower electric heating plates heat at the same time, the joint of the double-sided tape is quickly ironed, and part of the tape melts and penetrates into the corresponding cloth eye.

[0012] Preferably, in step one, when the cloth ends begin to be docked, the movable guide roller of the wrinkle-proof cloth storage mechanism begins to slowly descend, and the descending speed of the movable guide roller is synchronized with the speed of cutting the fleece and feeding the cloth, ensuring that the cloth tail of the previous double-layer fleece roll to be docked is in a stationary state.

[0013] The beneficial effects of the present invention are: The height of the double-layer flannel is raised by the movable guide roller, and 4-5m of cloth is stored before and after the movable guide roller, while the tail of the double-layer flannel stays on the cloth receiving table to reduce the occurrence of folds; The butt joint is double-sidedly glued and heated by the butt joint mechanism, so that the butt joint is not easy to fall off in the subsequent pile cutting process, which greatly improves the butt joint efficiency of the double-layer velvet cloth roll and ensures the yield rate of the cut pile.
