When the conventional cloth splicing device is used for splicing cloth ends (hereinafter referred to as a first cloth end and a second cloth end) of two rolls of cloth, the second cloth end is fixed at a designated position, a hot melt adhesive tape is horizontally placed on the second cloth end, the first cloth end is placed on the second cloth end and then is pressurized and heated to enable the two cloth ends to be bonded together, and then the first cloth end is cut by an automatic cutting system to complete cloth splicing. Because two ends of cloth have been bonded, automatic cutting system can not cut near hot melt adhesive tape, consequently can cut two ends of cloth simultaneously and cut off two ends of cloth simultaneously, for avoiding cutting two ends of cloth simultaneously, can reserve sufficient safe distance to a head of cloth, this just leads to leaving feather limit after connecing the cloth to accomplish, feather limit head of cloth has following problem:

firstly, the feather edge cloth head is additionally provided with a plurality of glue after passing through a glue dipping tank in the gluing process, so that the glue loss is increased;

secondly, the feather edge cloth is provided with glue, the cloth opening thickness is greatly increased, and the cloth opening is broken due to insufficient opening gap of the metering roller when the feather edge cloth passes through the metering roller, so that abnormal parking is caused;

thirdly, the adhesive on the cloth head belt is too much, the cloth head cannot be completely dried in an adhesive applying oven, and the undried adhesive remains on a reversing roller of an oven top roller chamber, so that the appearance and the performance of a produced product are influenced;

fourthly, in order to prevent the problems, the excessive feather edges need to be manually removed, so that the cloth connecting efficiency is low.

Then, the first suction fixing mechanism 110 is controlled to return to the initial position and the heating mechanism 160 is moved above the first cloth head 1 for heating, and specifically, the first driving member 112 is controlled to drive the first suction member 111 to move to the initial position in the direction indicated by the arrow F3, as shown in fig. 6. Then, the horizontal driving member 170 is controlled to drive the first suction attachment 111 and the heating rod 161 to horizontally move in place along the reverse direction of the first direction F1, at this time, the heating rod 161 moves to the side of the pressing fixing table 130, and then the third driving member 162 is controlled to drive the heating rod 161 to move down to the first cloth head 1, as shown in fig. 7, so that the heating rod 161 heats the first cloth head 1, the second cloth head 2 and the hot melt adhesive tape 3, welding of the two cloth heads is completed, and feather-free edge splicing is realized.

After the cloth is connected, the controller controls the heating rod 161, the second adsorption member 121 and the cutting knife 151 to reset. Specifically, the third driving member 162 is controlled to drive the heating rod 161 to move upwards in the direction indicated by the arrow F3, and then the horizontal driving member 170 is controlled to drive the first suction member 111 and the heating rod 161 to move in the first direction F1, so that the first suction member 111 and the heating rod 161 return to the initial positions, respectively, as shown in fig. 3.
