Description
Technical Field
The invention relates to the technical field of braiding machines, in particular to a shuttle of a plastic cylinder braiding machine.
Background
The plastic woven bag is widely applied to packaging materials of fertilizers, chemical products and other articles, and the main production process is to obtain the product by extruding a film, cutting, stretching into flat filaments and weaving the flat filaments by warps and wefts. In the production process, the plastic flat yarn warps and wefts wound into the spindle are woven into plastic woven cloth through a plastic cylinder braiding machine, and the plastic woven cloth is printed, cut and sewn to obtain the most common plastic woven bag.
The existing plastic circular knitting machine mainly comprises a creel, a warp and weft knitting assembly, a lifting density roller and a power device, wherein the creel is arranged on two sides of the warp and weft knitting machine, the lifting density roller is fixed above the warp and weft knitting machine, hundreds of spindles formed by winding plastic flat wires are fixed on the creel, plastic flat wire raw materials are provided for the knitting machine, firstly, the plastic flat wire raw materials are knitted into cloth-shaped plastic knitting cloth through the warp and weft knitting machine, then the cloth-shaped plastic knitting cloth is rolled through the lifting density roller, and finally, the cloth is conveyed to a cutting machine for cutting and sewing. The power device comprises a motor and a speed reducer, and is connected with a transmission belt through a gear to drive the warp and weft knitting machine and the winding machine to work. Wherein the warp and weft knitting machine and the density lifting roller share a set of power device, and the power device drives the warp and weft knitting machine and the density lifting roller through a transmission belt.
The diameter of the weft yarn bobbin is gradually reduced and the tension of the weft yarn is gradually increased during weaving, so that the fluctuation range of the woven cloth cover width is larger and reaches 1-2 cm, and the quality of woven cloth is seriously affected.
Disclosure of Invention
In order to solve the technical problems in the background technology, the invention discloses a shuttle of a plastic circular knitting machine.
The invention provides a shuttle of a plastic circular knitting machine, which comprises a shuttle frame and a weft yarn bobbin, wherein the weft yarn bobbin is rotationally connected with the shuttle frame through a head shaft and a tail shaft at two ends of the weft yarn bobbin, and the shuttle is characterized in that: the shuttle frame is provided with a rear swinging sleeve which is rotationally connected;
the tension change of the weft yarn drives the back swing sleeve to rotate, so that the tail shaft is pressed or loosened.
When the tension of the weft yarn is increased, the rear swing sleeve is driven to rotate, and the rear swing sleeve loosens the tail shaft, so that the rotation resistance of the tail shaft is reduced, and the tension of the weft yarn is reduced; when the tension of the weft yarn is reduced, the back swing sleeve reversely rotates and compresses the tail shaft, so that the rotation resistance of the tail shaft is increased, and the tension of the weft yarn is increased; the arrangement of the back swing sleeve not only ensures the stable yarn releasing speed of the weft yarn bobbin, but also stabilizes the tension of weft yarn, reduces the fluctuation range of the cloth cover width, and controls the fluctuation range of the cloth cover width to be within the range of 0-5 mm, thereby greatly improving the cloth cover quality; meanwhile, the invention has the advantages of simple structure, fewer wearing parts, simple maintenance and short time, and greatly improves the production efficiency.
In order to explain the power structure of the back swing sleeve rotation, in the scheme, a screw passing rod is arranged on the back swing sleeve, and weft yarns are woven after passing through the screw passing rod; the rear swing sleeve is connected with the shuttle frame through a spring. When the tension of weft yarn becomes large, the yarn passing rod is pulled to rotate, and the rear swing sleeve is driven to rotate; when the tension of weft yarn becomes smaller, the spring restoring force pulls the back swing sleeve to reversely rotate.
In order to illustrate the concrete structure of the rear swing sleeve, in the scheme, a tail shaft seat is arranged on the shuttle frame, and the rear swing sleeve is rotationally connected with the tail shaft seat; the rear swing sleeve is provided with a friction belt which is arc-shaped and sleeved with the tail shaft, one end of the friction belt is fixedly connected with the inner wall of the rear swing sleeve, and the other end of the friction belt is fixedly connected with the tail shaft seat; and when the friction belt rotates along with the rear swing sleeve, the friction belt is connected with or separated from the tail shaft.
In order to improve the connection strength of the friction belt, in the scheme, a rib belt is further connected between the friction belt and the inner wall of the rear swing sleeve.
The traditional rib belt is linear, the deformation range of the friction belt is affected, and therefore the performance of the friction belt is affected, so that the problem is further improved and solved, and specifically, the rib belt comprises a head belt, a middle belt and a tail belt which are connected in an integrated manner in sequence, and the head belt is connected with the friction belt; the middle belt is arc-shaped and concentric with the friction belt; the tail belt is connected with the inner wall of the rear swing sleeve. The arrangement of the middle belt increases the deformation range of the friction belt.
Because one end of the traditional thread passing rod is fixed, the other end of the traditional thread passing rod is suspended, weft threads are easy to fall off, and the effect of driving the rear swing sleeve is relatively poor, the problem is further improved and solved, and in particular, the shuttle frame is provided with a head shaft seat, and the head shaft is rotationally connected with the head shaft seat; the head shaft seat is rotationally connected with a front swinging sleeve, and the screw rod is fixedly connected with the front swinging sleeve and the rear swinging sleeve; the front swinging sleeve is also connected with the shuttle frame through the spring.
In order to improve the connection strength and rotation synchronism of the front swing sleeve and the rear swing sleeve, in the scheme, a swing arm is fixedly connected between the front swing sleeve and the rear swing sleeve.
In order to make the stress of the back-and-forth swing sleeve uniform, in the scheme, the thread passing rod and the swing arm are symmetrically arranged relative to the weft yarn bobbin.
The tension of the conventional weft yarn is easily interfered by the elastic guide component when the weft yarn is woven, so that the problem is further improved and solved, and particularly, the shuttle frame is also provided with a guide rod assembly, and the weft yarn is woven after passing through a ceramic tube hinged on the guide rod assembly. When weft pressure is normal, the ceramic tube is hidden in the plastic shell and is supported by the hinge shaft; when the weft yarn pressure is reduced, the ceramic tube rotates under the action of gravity and applies pressure to the weft yarn, so that the weft yarn pressure is increased; the ceramic tube replaces the traditional elastic guide component, and the tension is kept stable.
In order to illustrate the concrete structure of the guide rod assembly, in the scheme, the guide rod assembly comprises a guide rod, the lower end of the guide rod is connected with the shuttle frame, and the upper end of the guide rod is provided with a guide wire ring; a plastic shell is arranged below the guide wire ring, one end of the plastic shell, which is far away from the guide rod, is hinged with a throwing block, and the ceramic tube is fixedly connected with the throwing block. Weft threads sequentially pass through the ceramic tube and the yarn guide ring to be woven.
