Description

Automatic wire winding and knot detecting device of computer gun-shaped carpet machine

Technical Field

The invention relates to the technical field of a gun-shaped carpet machine, in particular to an automatic wire winding and knot detecting device of a computer gun-shaped carpet machine.

Background

The gun-punched carpet weaving is to insert pile yarns into carpet base cloth by utilizing steel needle penetration to form various patterns. When the knitting process starts, the cloth penetrating needle drives the carpet thread and penetrates into the carpet base fabric, so that the warp and weft of the base fabric are shifted to form holes, the carpet thread which penetrates into the cloth penetrating needle thread hole and is driven by the thread pushing needle is conveyed to the other side of the base fabric through the base fabric hole penetrated by the cloth penetrating needle, the cloth penetrating needle and the thread pushing needle are withdrawn out of the carpet base fabric, the carpet base fabric is physically reset in warp and weft and clamped with the carpet thread to complete a needle step, the above actions are repeated until the knitting of a certain pattern or pattern is completed, the needle is stopped, and the front end of the cloth penetrating needle can bring out a carpet thread tail when the needle is stopped. When changing carpet threads of different colors or taking up patterns, the needles must be re-needled. In the carpet manufacturing process, because the carpet pattern or the carpet process is required, the needles are stopped for multiple times and then the needles are restarted, at the moment, the carpet thread tails brought out during each needle stopping can be left on the back surface of the carpet, so that irregular bulges on the back surface of the carpet are caused, and the carpet thread tails are required to be removed, so that the requirement of post-process processing can be met, and the quality of products is ensured. For this reason, the current method is to manually pull out or trim the wire tail flat, which causes manpower waste or poor quality.

In addition, carpet wire for gun knitting is commonly used with multiple strands to achieve the desired density. In the process of wire rod winding into wire coils, the situation of wire rod splicing is frequently encountered, and a common method is to splice by adopting wire bonding. Because the outer diameter of the wire with the knot is increased by more than one time compared with that of a normal wire, when even one knot in the coil goes to the position of the cloth penetrating needle hole, the wire is blocked by the needle hole to cause blocking, and the corresponding part to be woven is in a shortage of the wire, and stopping arrangement is not carried out until the alarm is triggered or the machine is found by a machine viewer when the wire is piled up to a large pile. However, the broken line part which is broken before the stop is repaired manually or is removed first and then repaired. Thus, a great deal of labor force and resources are wasted, and the production efficiency and the production cost are seriously affected.

The automatic wire winding and knot detecting device of the computer gun carpet machine has the following working processes:

when the equipment starts to work, the carpet wire 4-2 pulled out from the carpet wire reel 4-1 passes through the wire breakage detector 8, then passes through a gap inlet formed between the inner edge 9-4-1-1 of the wire pressing block inclined surface and the bottom edge of the deep slot on one side of the wire collecting deep slot 9-2-1, passes through the wire collecting deep slot 9-2-1 and the piercing gun transmission seat 1, and then passes through the cloth penetrating needle wire hole 6-3.
