Description

The invention relates to knit shorts, namely, devices for straightening and squeezing knitted fabric, and can be used for finishing knit rounds knitted in wiring and requiring straightening and squeezing. A device for unfolding a knitted fabric is known, which comprises a straightener and a means for holding the straightener. A device for assembling a tricot canvas is known, comprising a distributor in the shape of a ball or cylinder, rounded on its end surface, freely positioned inside the canvas, and means: for holding the equalizer consisting of several electromagnets holding the dispersion inside the magnet 1 by forces. The disadvantage of this device is the uneven application of tensile forces to / julotnu around its perimeter when spraying. In the middle part of the stretcher, the web deforms more smoothly, and on the edges, the deformation increases sharply. This leads to distortions of the looped structure of the web and, accordingly, a decrease in its grade. At the same time, the straightener does not provide for the alignment of the geometric structure of the web, and the web has a wide margin, which reaches ± 10% of its average width. This defect when cutting leads to a large waste of fabric in the waste. Variations of the straightener around the center of mass are possible, causing uneven frictional forces of the web along the straightener applied to the edges of the straightener. It also contributes to the formation of distortions and diversity of the web. It is necessary to change expensive ferromagnetic spreaders y) and to the processing of webs of various diameters. When using a ball-shaped spreading machine for processing large-diameter cloths (up to 1.2 m), at least 3-4 electromagnets are needed around the spreading ball to balance it. In this case, there are additional difficulties in coordinating the work of all electromagnets. -. .37 The aim of the invention is to expand the technological capabilities of the device. This is achieved by the fact that the means for holding the spreader consists of a solenbide with a core with the formation of an annular gap for the passage of the web, while the spreader is mounted on the upper end of the core with the possibility of removal. The straightener consists of a disk mounted on the core, and rollers mounted on the rim of the disk in two rows, with the formation of an annular gap between them, and a rubber ring installed in the gap, the straightener may consist of a ring mounted on the upper core, and frame attached to the ring., FIG. 1 shows the described device, general view; ha of fig. 2 - view along the arrow. And in FIG. one; in fig. 3 - device, general view, version; in fig. 4 is a view along arrow B in FIG. 3; in fig. 5 is a sectional view BB in FIG. 3. A device for straightening knitted fabric 1 contains pi as the rule and means. to hold the spreader. The means for holding the radio controller consists of a solenoid 2 with the core 3 to form an annular gap for the passage of the blade 1, with a straightener. mounted on the upper end of serdnik 3 with the possibility of removal. The spreader can consist of a disk 4 mounted. with kami 5 fixed on its rim in two rows with the formation of an annular gap between them, and a rubber ring 6 installed in the gap (see Fig. 1), or in the form of a ring 7 mounted on the upper end of the core 3 and the frame 8, attached to the ring 7 (see Fig. 3-5). The straightener is mounted on the upper end of the saddle 3, for example, by screwing it with a nut and a lock nut.

The proposed device works as follows.

The core 3, inserted into the web 1 with a removable straightener attached to it, is held by two 45-fold electromagnetic forces on the rim of the disk, with obrasolanoid 2 covering the core 3. By positioning an annular gap between them, and 1 along the core 3, passing through the core 3 in the gap the inter-new ring installed in the gap, the core and the solenoid, enters at 3. The device according to n.J, distinguishes the distributor. Thanks to the circular shape with. By the fact that the straightener consists of a ring, a stretcher extending longitudinal and 50 mounted on the upper end of the core, the transverse loads are uniformly applied to the frame fixed on the ring.

possibility of removal

2. The device according to claim 1, characterized in that the straightener consists of a disk mounted on the core, and rollers. 34 around the perimeter of the tubular web 1. Therefore, the hinge structure of the web is aligned. The formation of distortions of the looped structure and different widths is eliminated. Then the canvas smoothly slides onto the frame 8 (see Fig. 3), acquiring the shape of a folded canvas. At the same time, the friction force of the web against the spreader, which seeks to displace it into a smudging device, is balanced by both the electromagnetic forces of the solenoid and the gravitational force of the straightener, which significantly reduces power consumption, i.e., increases the efficiency of the device compared to the prototype. The design of the proposed device is more perfect: it is easier to set up to balance the straightener in a magnetic field when processing canvases. Different diameters, the solenoid and expensive core do not change. Only straighteners that are made from conventional non-magnetic lightweight materials, such as plastics, change. Thus, the technological capabilities of the device have been expanded, the high-quality processing of the web has been ensured, the cost price of knitwear has been reduced by reducing waste when cutting. .
