Description

Technical Field

[0001] This utility model relates to the field of thick fabric processing technology, and in particular to a special winding device for thick fabrics with efficient fixing and stretching functions. Background Technology

[0002] In modern industrial production and daily life, thick fabrics are finding increasingly wider applications due to their unique performance advantages. In home decoration, thick fabrics such as sofa upholstery and carpets not only need to have good abrasion resistance and stain resistance, but also need to have a soft touch and beautiful texture to meet consumers' pursuit of home quality. In the industrial field, the thick fabrics used for conveyor belts in mining transportation need to withstand huge tensile forces and friction, and have high strength and tear resistance. Thick fabrics such as warehouse tarpaulins need to withstand wind, sun and rain erosion, and have excellent waterproof and anti-aging properties.

[0003] However, existing thick fabric winding devices still have the following problems: 1. The existing thick fabric winding devices use simple manual clamps for fixing, which cannot be adjusted according to the thickness of the thick fabric. When facing thick fabrics of different materials, it is difficult to control the clamping force. Excessive force will cause indentations, deformation or even damage to the fabric surface, while insufficient force will easily cause displacement during winding, resulting in wrinkles and uneven tension of the fabric, which will greatly increase the scrap rate; 2. During the winding process, the winding speed of existing thick fabric winding devices fluctuates greatly, resulting in inconsistent winding tension of the fabric. This not only affects the appearance quality of the finished product, but also brings many inconveniences to subsequent processing and use. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model embodiment is to provide a special winding device for thick fabrics with efficient fixing and stretching functions, which can solve the technical problems of the existing technology that the fixing structure cannot flexibly adjust the clamping force according to the fabric thickness and the large fluctuation of the winding speed leads to inconsistent tightness of the fabric winding.

[0005] In a first aspect, this utility model provides a special winding device for thick fabrics with efficient fixing and stretching functions, comprising a base, a first U-shaped plate fixedly connected to the upper left rear part of the base, a connecting plate fixedly connected to the upper left front part of the base, a winding mechanism inserted and installed at the front end of the first U-shaped plate, an mounting plate fixedly connected to the upper middle rear part of the base, a stretching mechanism inserted and installed at the rear end of the mounting plate, an L-shaped plate fixedly connected to the upper right rear part of the base, two through guide grooves opened at the front end of the L-shaped plate, a fixing mechanism being movably sleeved in the two guide grooves, and a fixing hole through the upper and lower parts being opened at each of the four corners of the upper end of the base;

[0006] The winding mechanism includes a first motor base, a first motor, a first circular gear, a second circular gear, a first transmission wheel, a toothed transmission belt, a second transmission wheel, a movable rod, and a winding roller;

[0009] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0010] In this embodiment of the invention, a third motor drives a bidirectional lead screw to rotate, which in turn moves the transmission block and guide block, causing the fixed clamping plate to quickly clamp the thick fabric. The clamping force can be flexibly adjusted according to the fabric thickness to ensure that the thick fabric is stable and does not slip or deviate during stretching and winding, thus avoiding processing quality problems caused by fabric loosening. Driven by a second motor, the upper active stretching roller, the lower active stretching roller, the upper driven stretching roller, and the lower driven stretching roller cooperate with each other. Power is transmitted by the third and fourth circular gears to achieve uniform and stable stretching of the thick fabric, which can effectively eliminate fabric wrinkles, improve fabric flatness and texture, and optimize finished product quality.
