Description

Gathering device of carbon fiber multi-layer angle knitting machine

technical field

The invention belongs to textile machinery, in particular to a yarn gathering device of a carbon fiber multi-layer corner loom.

Background technique

Carbon fiber multi-layer corner loom is a new weaving equipment at home and abroad. At present, the weaving process of carbon fiber multi-layer angle knitting machine in China is to weave multi-strand sheet carbon fiber into a carbon fiber fabric with a certain width and thickness. (The current carbon fiber process is 20 layers, 90 pieces/layer, a total of 1800 carbon fibers) and sent to the entrance of the main machine of the weaving machine at the same time. Among them, the warp let-off part of the carbon fiber multi-layer corner loom includes a warp let-off part, a tension part and a gathering part. Since the width of the let-off part is larger than that of the tension part, if the warp yarn directly enters the tension mechanism from the let-off mechanism, interference will occur between the carbon fiber thread and the mechanism; at the same time, due to the long distance between the let-off mechanism and the tension mechanism, carbon fibers will be Sagging occurs, causing the carbon fibers of each yarn layer to interfere with each other, causing friction, and causing the surface of the carbon fibers to "fluff". Since the above factors will cause serious wear and tear of carbon fiber, seriously affect product quality, and increase the scrap rate, my country still relies on imports of carbon fiber, thus causing huge economic losses.

Patent application number: 200810059322.8 discloses a yarn-gathering device for compact spinning, including a bracket and a yarn-gathering board. A pair of protrusions are arranged on both sides of the bracket. The two protrusions are mirror-symmetrical to the center of the bracket. Grooves and gears are provided on the bracket. The bosses on the box are snapped together, a pair of catches are provided on the upper part of the gathering board and are buckled with the corresponding protrusions on the bracket, a pair of feet are provided on the lower part of the gathering board, and a gathering airflow guide rib is arranged inside the two legs, and the gathering airflow The height of the guide rib is lower than the height of the feet, and the height difference is greater than the thickness of the conveyor belt. Its advantages are: the yarn gathering device is between the drafting roller and the holding roller, straddles the conveyor belt and is elastically mounted on the sliding surface, guided by the guide ribs on the yarn gathering plate, it can make the yarn before entering the suction channel The airflow exerts directional and effective pressure on the strands, and the airflow is effectively used above the strands to reduce negative pressure and save energy. The yarn gathering device is also guided by the three airflow guide ribs on the yarn gathering board when spinning strands, so that the two strands are not easy to be merged or entangled, and the quality of strands is improved. The above-mentioned patents are only applicable to conventional looms. In our country, since the carbon fiber multi-layer fabric is still in the research and development stage, it cannot be realized according to the traditional loom. Compared with the prior art disclosed above, the yarns are very light and will not fluff each other due to friction, and the fluffing of ordinary yarns on traditional looms will not affect the quality of the fabric, so all direct yarn gathering devices are used, and at the same time only Single layer of yarn gathered. Multi-layer fabrics are basically hand-woven. The carbon fiber fabric industry urgently needs to develop a yarn gathering device that enters the tension part from the let-off part to ensure that the carbon fibers are flat and non-interfering.

Example

Please refer to Figures 1 to 4, a yarn gathering device of a carbon fiber multi-layer angle knitting machine, including two triangular first yarn passing board assemblies 1 and second yarn passing board assemblies 2 perpendicular to the warp direction. Two pieces of the first yarn passing board support form an open triangle shape through the angle connecting bracket 24, and the position of the second yarn passing board assembly 2 is set to: the second yarn passing board assembly corresponds to the triangle of the first yarn passing board assembly The opening position is set and is perpendicular to the centerline of the triangle. The distance between the second yarn passing board assembly and the triangular opening position of the first yarn passing board assembly is as close as possible under the tension condition of the carbon fiber thread.

The first yarn passing board assembly 1 includes a set of first yarn passing board supports 11 and twelve first yarn passing boards 12, and the working width is the same as that of the warp let-off component. Twelve pieces of first yarn passing boards 12 are fixed on the first yarn passing board bracket 11 by bolts, six pieces are arranged on the left and right respectively, and the installation heights corresponding to the first yarn passing boards on the left and right are the same, and the installation height is the same as that of the six-layer main shaft of the warp let-off component. One-to-one correspondence, there are 300 yarn passing round holes on the first yarn passing board 12, six pieces on the left and right sides, a total of 1800 yarn passing round holes on the left or right first yarn passing board 12, and the first yarn passing holes on the left and right sides The board has 3600 yarn passing round holes in total, and the yarn passing round holes are all glued with yarn passing ceramic rings 3 . The yarn outlet port of the yarn passing ceramic ring is provided with a circular arc guide angle 3-1, which can avoid scratches when the direction of the carbon fiber yarn changes. The second yarn passing board assembly 2 perpendicular to the warp direction includes one set of second yarn passing board supports 21, six second yarn passing boards 22 and six groups of connections connected to the carbon fiber multilayer angle knitting machine tension component frame. The support 23 is connected vertically with the second yarn passing plate support, and its working width is the same as that of the tension member. The six second yarn passing boards 22 are fixed on the second yarn passing board bracket 21 sequentially by bolts from high to low. 300 round holes for passing yarn are arranged, and six second passing round holes for passing yarn have 3600 round holes for passing yarn, all of which are bonded with ceramic rings 3 for passing yarn.

The second yarn passing board support is vertically fixed with a connecting bracket, and one end of the connecting bracket 23 is connected with the second yarn passing board bracket 21 by a bolt, and the other end is connected with a carbon fiber multi-layer corner loom tension component frame by a bolt, Six groups of connecting brackets 23 are respectively arranged in three groups from high to low.

In order to avoid friction and fluffing of carbon fibers, the carbon fiber multi-layer angle knitting machine adopts active yarn feeding technology, and a tension adjustment mechanism is installed in the tension mechanism, and a sensor is installed to monitor the tightness of the carbon fiber thread. When the carbon fiber thread is found to sag due to its own weight, a signal is sent to The servo motor of the let-off mechanism, at this time, the servo motor reverses to tighten the carbon fiber thread. In particular, it should be noted that the carbon fiber wire is composed of several carbon fiber filaments into an adjusted strip carbon fiber wire similar in shape to an audio tape, and the strip carbon fiber wire itself is relatively heavy. The color is black. According to the design requirements, the fabric needs to be six layers, so it needs to be woven with 20 layers of strip carbon fiber threads.

The yarn gathering device is arranged between the let-off part and the tensioning part of the carbon fiber multi-layer corner loom, and the entire plane positions of the two triangular first yarn passing plate assemblies of the yarn gathering device are respectively perpendicular to the moving direction of the carbon fiber line. The first yarn passing board assembly of the yarn gathering device is to draw the carbon fiber yarn sent out by the let-off part through the yarn passing ceramic ring of the first yarn passing board horizontally. That is, the carbon fiber thread does not change the direction of the carbon fiber thread before entering the first yarn passing plate assembly, and each carbon fiber thread passes through a yarn passing ceramic ring corresponding to its position on the first yarn passing plate, and the horizontally moving carbon fiber thread leaves the ceramic ring. After the ring exits, it will change its direction. All the carbon fiber threads will be concentrated on the second yarn passing board assembly and pass through 3600 yarn passing ceramic rings on the second yarn passing board respectively. After passing through the second yarn passing board assembly, the carbon fiber threads will enter the tension horizontally Parts, play the function of gathering yarn. The main purpose of the second yarn passing board assembly is to concentrate all the carbon fiber threads drawn from the first yarn passing board assembly from two directions into the same range as the width of the tension member, and then enter the main machine.
