Closely spin the fine spining machine shape tube
Technical field
The utility model relates to a kind of shape tube, is meant a kind of fine spining machine shape tube that closely spins especially.
Background technology
Spinning industry belongs to labour intensive profession enterprise, and profit is low, dog-eat-dog, and enterprise must promote the market competitiveness by improving the quality of products, reduce to consume.The tight spinning equipment of spun yarn can improve yarn fineness, improves yarn evenness, improves the yarn row yielding, receives the favor of enterprise, closely spins fine spining machine in textile enterprise's extensive use.Closely spin shape tube on the fine spining machine and in the friction repeatedly of yarn, damage easily, like untimely replacing, the fineness, the bar that influences yarn are done and are reached carrying out smoothly of compact spinning.But after closely spinning the wearing and tearing of fine spining machine shape tube at present, need to change the whole piece shape tube, and shape tube costs an arm and a leg, and adopts compact spinning like this, when improving yarn qualities and row yielding, the machine material consumption that closely spins fine spining machine is higher than common fine spining machine.
The utility model content
The utility model technical problem to be solved is: a kind of fine spining machine shape tube that closely spins is provided; After the shape tube wearing and tearing, need not to change the whole piece shape tube, practiced thrift raw material; Greatly reduce the use cost of closely spinning fine spining machine, alleviated mechanician's the amount of labour simultaneously.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of fine spining machine shape tube that closely spins; Comprise the shape tube body, the arc wear surface of said shape tube body is provided with axial mounting groove, and fixed installation is useful on the wear rib that contacts with yarn in the said mounting groove.
As a kind of preferred scheme, said wear rib is the stainless steel wear rib.
As a kind of preferred scheme, said wear rib embeds said mounting groove and bonds through glue with the shape tube body.
As a kind of preferred scheme, the wear surface of said wear rib is the arc wear surface, and the radian of the arc wear surface of said wear rib and the arc wear surface of shape tube body is suitable.
After having adopted technique scheme, the effect of the utility model is: because a kind of fine spining machine shape tube that closely spins comprises the shape tube body; The arc wear surface of said shape tube body is provided with axial mounting groove; Fixed installation is useful on the wear rib that contact with yarn in the said mounting groove, the shape tube after the improvement and yarn contact friction be wear rib, and wear rib can be changed separately after in a single day wearing and tearing; Need not to change the shape tube body; Practice thrift raw material like this, greatly reduced the use cost of closely spinning fine spining machine, alleviated mechanician's the amount of labour simultaneously.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the partial structurtes sketch map of the utility model embodiment;
Fig. 2 is the end face partial schematic diagram of the shape tube of the utility model embodiment;
In the accompanying drawing: 1. shape tube body; 2. wear rib; 3. glue layer.
The specific embodiment
Through specific embodiment the utility model is done further to describe in detail below.
A kind of fine spining machine shape tube that closely spins, as depicted in figs. 1 and 2, it comprises shape tube body 1, and the arc wear surface of said shape tube body 1 is provided with axial mounting groove, and fixed installation is useful on the wear rib 2 that contacts with yarn in the said mounting groove.Wherein, preferred, said wear rib 2 is a stainless steel wear rib 2.Said wear rib 2 embeds said mounting groove and bonds through glue with shape tube body 1.The wear surface of said wear rib 2 is the arc wear surface, and the radian of the arc wear surface of said wear rib 2 and the arc wear surface of shape tube body 1 is suitable.Certainly; The shape of mounting groove can be multiple, as long as wear rib 2 can be embedded in the mounting groove, it is very smooth that stainless steel wear rib 2 its wear surfaces can be done; And material is not easy to wear; In addition, wear rib 2 can be through glue layer 3 bondings with shape tube body 1, also can be the fixed form bonding through other.
The operation principle of the utility model is: shape tube in use; Wear rib 2 direct and yarn contact frictions, wear rib 2 is wear-resisting, and if can change wear rib 2 separately after wear rib 2 wearing and tearing; Thereby need not to change whole shape tube; Practice thrift raw material, greatly reduced the use cost of closely spinning fine spining machine, alleviated mechanician's the amount of labour simultaneously.
