Description

Technical Field

[0001] The utility model belongs to the technical field of cloth weaving processing, and particularly relates to an electric heating width opening device of a circular knitting machine. Background Art

[0002] Braiding machines are frequently used in fabric weaving and processing, among which circular braiding machines are used more frequently due to their high weaving efficiency. After being woven and formed by a circular braiding machine, the grey cloth moves downward in a cylindrical shape and is divided into a piece of cloth by an opening device for easy transportation and storage. The opening device on the existing circular braiding machine is usually a physical cutting device such as a circular blade fixedly set on a rotating working frame. After a certain period of use, the circular blade gradually becomes less sharp due to wear. When the wear reaches a certain degree, it will cause the grey cloth to open unsmoothly, which on the one hand affects the opening efficiency of the grey cloth, and on the other hand causes the grey cloth on the cloth frame to be pulled due to failure to open in time, resulting in large-area tear marks, pitting and oblique folds on the opening edge of the grey cloth, which affects the product quality, increases the cost of secondary processing and causes waste of grey cloth. In order to reduce or avoid the defects of the grey cloth, the circular blade needs to be replaced frequently. For example, the replacement frequency of the circular blade when weaving FDY fabrics cannot exceed 1 month, and the replacement frequency of the circular blade when weaving processed silk cannot exceed 2.5 months, which greatly increases the production cost investment and restricts the improvement of production efficiency. Utility Model Content

[0003] The utility model aims to provide an electric heating width opening device for a circular knitting machine to solve the problem that the physical cutting equipment such as the circular blade of the existing circular knitting machine is not replaced in time, resulting in a high rate of poor quality of the opening of the grey cloth or requiring frequent replacement, thereby increasing production costs.

[0005] The utility model proposes an electric heating width opening device of a circular knitting machine, the structure of which includes a rotatably arranged working frame, a tensioning mechanism and a width opening mechanism arranged on the working frame, the tensioning mechanism includes a first guide cloth frame and a tension roller, the first guide cloth frame is arranged on the working frame, the tension roller is arranged below the first guide cloth frame, the woven and formed grey cloth is arranged around the first guide cloth frame to form a transverse tension, the lower end of the grey cloth is arranged around the tension roller to form a longitudinal tension and a downward moving force, the width opening mechanism is arranged between the first guide cloth frame and the tension roller, the width opening mechanism includes a mounting seat and an electric heating wire, the mounting seat is fixedly arranged on the working frame, the electric heating wire is fixedly arranged on the mounting seat, and the electric heating wire contacts the grey cloth to cut the grey cloth;

[0006] Based on the above technical scheme, the woven cylindrical grey cloth passes through the electric heating wire of the opening mechanism at a uniform speed under the action of the tensioning mechanism. Under the high temperature of the electric heating wire, the grey cloth can be divided as soon as it contacts the electric heating wire. The grey cloth will not be subjected to additional force during the cutting process. The cloth generated by the opening device has a smooth opening edge without defects such as tear marks and oblique creases. The product quality is good and the opening efficiency is high.

[0007] Furthermore, the first cloth guide frame is a V-shaped frame symmetrically arranged on the working frame, the grey cloth is arranged around the outside of the first cloth guide frame and is in a flat funnel shape, and the opening mechanism is arranged at the bottom end of the first cloth guide frame. This design can make the tension of the grey cloth more stable when passing through the heating wire and the formed edge more neat.

[0008] Furthermore, the tensioning mechanism also includes a second guide cloth rack, which is arranged on the side of the first guide cloth rack, the lower end of the second guide cloth rack is fixed on the working frame, and the upper end is provided with a cross bar, and the cross bar is close to the outer side of the grey cloth. This design can make the grey cloth a tensioned small plane instead of a convex ridge when passing through the heating wire, which is conducive to the smooth cutting of the heating wire.

[0009] Furthermore, a connecting seat is fixedly provided on the working frame near the opening mechanism, a mounting hole is opened on the connecting seat, the first guide cloth frame is installed in the mounting hole, a guiding inclined surface is provided on the upper surface of the connecting seat, and the heating wire is suspended on the guiding inclined surface. This design is beneficial for the grey cloth to always be in a plane when opening the width, which not only ensures the fixity of the cloth opening line, but also assists the grey cloth to move down smoothly.

[0010] Furthermore, the guide slope is provided with an avoidance groove, and the heating wire extends into the avoidance groove. This design can ensure that the heating wire is in full contact with the grey cloth, avoiding the possibility of the heating wire contacting the connecting seat to damage the cloth or the heating wire and the grey cloth being incompletely contacted, thereby improving the opening quality of the grey cloth.

[0011] Furthermore, the connection seat is provided with a plurality of mounting holes, so as to facilitate the adjustment of the opening width of the first cloth guide frame, thereby being suitable for the opening width of grey cloths of different materials.

[0012] Furthermore, the heating wire is fixed on the mounting seat in a U-shape, and the U-shaped design can maintain a certain rigidity of the heating wire when in contact with the grey cloth without deformation, thereby achieving stability of the grey cloth opening route.

[0013] Furthermore, the opening mechanism is connected to a controller, and the controller is provided with a gear adjustment switch to adjust the heating power of the electric heating wire according to the downward movement speed of the grey cloth and the thickness of the grey cloth.
