Description
Technical Field
The invention relates to the technical field of knitting machines, in particular to a shuttle of a plastic cylinder knitting machine.
Background
The plastic woven bag is widely applied to packing materials of articles such as fertilizers, chemical products and the like, and the main production process is to utilize plastic raw materials, extrude a film, cut and stretch the film into flat filaments, and then weave the flat filaments by warps and wefts to obtain the product. In the production process, a plastic flat filament wound into a spindle is woven into plastic woven cloth by a plastic cylindrical weaving machine in a warp-weft mode, and the plastic woven cloth can be printed, cut and sewn to obtain the most common plastic woven bag.
The structure of the existing plastic cylinder knitting machine mainly comprises a creel, a warp and weft knitting assembly, a density lifting roller and a power device, wherein the creel is arranged at two sides of the warp and weft knitting machine, the density lifting roller is fixed above the warp and weft knitting machine, hundreds of yarn spindles formed by winding plastic flat yarns are fixed on the creel to provide plastic flat yarn raw materials for the knitting machine, the plastic flat yarn raw materials are firstly knitted into cloth-shaped plastic knitted cloth through the warp and weft knitting machine, then the plastic flat yarn raw materials are wound through the density lifting roller and finally 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-weft knitting machine and the density lifting roller share one set of power device, and the power device drives the warp-weft knitting machine and the density lifting roller through a transmission belt.
The diameter of a weft yarn bobbin on a shuttle of the plastic cylinder knitting machine is gradually reduced during knitting, and the tension of the weft yarn is gradually increased, so that the fluctuation range of the width of a knitted cloth surface is large and reaches 1-2 cm, and the quality of the knitted cloth is seriously influenced.
Disclosure of Invention
In order to solve the technical problem in the background technology, the invention discloses a shuttle of a plastic cylinder knitting machine.
The invention provides a shuttle of a plastic cylinder 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 in rotating connection;
the tension change of the weft yarn drives the rear swinging sleeve to rotate, so that the tail shaft is pressed or loosened.
When the tension of the weft becomes large, 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 is reduced; when the tension of the weft becomes small, the rear swinging sleeve rotates reversely and compresses the tail shaft, so that the rotation resistance of the tail shaft is increased, and the tension of the weft is increased; the arrangement of the rear swing sleeve not only ensures the stable yarn releasing speed of the weft yarn bobbin, but also stabilizes the tension of weft yarns, reduces the fluctuation range of the cloth cover breadth, controls the fluctuation range of the breadth within the range of 0-5 mm, and greatly improves the cloth cover quality; meanwhile, the invention has simple structure, fewer easily-damaged parts, simple maintenance and short time, and greatly improves the production efficiency.
In order to explain the power structure of the rotation of the rear swing sleeve, in the scheme, a yarn passing rod is installed on the rear swing sleeve, and weft yarns are woven after passing through the yarn passing rod; the rear swing sleeve is connected with the shuttle frame through a spring. When the tension of the weft becomes large, the thread passing rod is pulled to rotate and drives the rear swinging sleeve to rotate; when the tension of the weft becomes small, the spring restoring force pulls the back swing sleeve to rotate reversely.
In order to explain the specific 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 rotatably connected with the tail shaft seat; the rear swing sleeve is provided with an arc friction belt 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 swinging 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, the friction belt is connected with a rib belt between the inner walls of the rear swing sleeves.
The traditional rib belt is linear and can affect the deformation range of the friction belt, so that the performance of the friction belt is affected, and the problem is further improved and solved; the middle belt is arc-shaped and is concentric with the friction belt; the tail belt is connected with the inner wall of the rear swing sleeve. The deformation range of the friction belt is enlarged due to the arrangement of the middle belt.
Because one end of the traditional thread passing rod is fixed, and the other end is suspended, the weft thread is easy to fall off, and the effect of the driving back swing sleeve is poor, the problem is further improved and solved; the head shaft seat is rotatably connected with a front swing sleeve, and the wire passing rod is fixedly connected with the front swing sleeve and the rear swing sleeve; the front swing sleeve is also connected with the shuttle frame through the spring.
In order to improve the connection strength and the rotation synchronism of the front and back swing sleeves, in the scheme, the front swing sleeve and the back swing sleeve are fixedly connected with a swing arm.
In order to ensure that the front and back swing sleeves are evenly stressed, in the scheme, the lead screw and the swing arm are symmetrically arranged relative to the weft yarn bobbin.
The shuttle frame is further improved to solve the problem that the tension of the conventional weft is easily interfered by an elastic guide part when the weft is woven, and particularly, the shuttle frame is also provided with a guide rod component, and the weft is woven after passing through a ceramic tube hinged on the guide rod component. When the pressure of the weft is normal, the ceramic tube is hidden in the plastic shell and is supported by the articulated shaft; when the pressure of the weft becomes small, the ceramic tube rotates under the action of gravity and applies pressure to the weft, so that the pressure of the weft is increased; the ceramic tube replaces the traditional elastic guide component, and the tension keeps stable.
In order to explain the specific 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 installed below the wire guide ring, a throwing block is hinged to one end, far away from the guide rod, of the plastic shell, and the ceramic tube is fixedly connected with the throwing block. The weft threads sequentially penetrate through the ceramic tube and the guide wire ring to be woven.
