Description

Technical Field

[0001] The present invention relates to the technical field of textile stretching, in particular to a textile stretching device and a stretching method thereof. Background Art

[0002] The background of textile stretching devices is closely related to the tensile performance testing of textiles. First of all, tensile performance is one of the important indicators for measuring the quality of textiles, including elastic modulus, tensile strength, elongation, etc. These indicators reflect whether the textile can withstand a certain tension during use without easily breaking or deforming. Secondly, the fabric tensile tester is a device specially used to test these properties. It is mainly composed of a sample clamping device, a tensile transmission mechanism, a force measuring device, a data acquisition and processing system, etc. In addition, some innovative equipment such as a biaxial fixing device can achieve directional stretching of textiles to eliminate unwanted bulges and wrinkles. In general, the emergence of textile stretching devices provides a scientific and accurate basis for the quality inspection of textiles, and also brings substantial convenience to the production and use of textiles.

[0003] Most current textile stretching devices use multiple rollers or a group of clamping devices to stretch textiles. This stretching method is too direct, resulting in uneven stretching of the textile and wrinkles. In view of this, we provide a textile stretching device and a stretching method thereof.

[0018] A stretching device for textiles and a stretching method thereof, comprising the following steps:

[0019] S1. A set of stretching components are staggered and fixed inside the stretching chamber. When using this device, the stretching motor drives the active shaft to rotate, and through the mutual engagement of bevel gear 1 and bevel gear 2, it simultaneously drives a set of passive shafts to rotate. Utilizing the characteristics of the reciprocating thread groove, when the passive shaft rotates, one thread groove of the reciprocating thread groove pushes the connecting block and the stretching block upward;

[0020] S2. When the connecting block slides to the top of the reciprocating thread groove, it enters another thread groove through the transition curve groove, and then pushes the connecting block and the stretching block downward, causing the stretching block to achieve reciprocating lifting motion. Through the reciprocating lifting motion of the stretching block and the staggered stretching components, the textile being transported inside the stretching chamber is repeatedly stretched in multiple sections and at multiple angles as it passes through;

[0021] S3. A set of steam ironing components are fixed between the stretching components in an alternating manner, one above and one below. A connecting plate is suspended in the air inside the stretching chamber via a fixed shaft. When the servo motor is in operation, it drives the turntable and the connecting post on the turntable to rotate. The connecting post is connected to the drive slot. When the connecting post rotates to the "12 o'clock" and "6 o'clock" directions, the connecting plate is in a vertical position. When the connecting post rotates to the "3 o'clock" and "9 o'clock" directions, the steam ironing head reaches its maximum swing angle, thereby causing the steam ironing head to reciprocate around the fixed shaft to iron the textile passing through it.

[0022] S4. Before using the device, clamp the entire roll of textile and place it on the table, open the operating window, first pass one end of the textile through the multiple components inside the stretching chamber, and then place it in the groove on the outer wall of the winding roller. By rotating the fixing clamp, it is connected to the groove. Through the connection between the pin and the socket, the action of the spring, and the mutual connection between the arc block and the limit groove on the inner wall of the socket, one end of the textile is fixed inside the winding roller.

[0023] Compared with the prior art, the present invention provides a stretching device and a stretching method for textiles, which have the following beneficial effects:

[0024] 1. The textile stretching device and stretching method thereof are characterized in that a group of stretching components are staggered and fixed inside a stretching chamber. When the device is used, a stretching motor drives the active shaft to rotate, and through the mutual engagement of bevel gear one and bevel gear two, it simultaneously drives a group of passive shafts to rotate. Utilizing the characteristics of the reciprocating thread groove, when the passive shaft rotates, one thread groove of the reciprocating thread groove pushes the connecting block and the stretching block to move upward. When the connecting block slides to the top of the reciprocating thread groove, the connecting block enters the other thread groove through the transition curve groove, and then pushes the connecting block and the stretching block to move downward, thereby enabling the stretching block to achieve reciprocating lifting motion without changing the rotation direction of the passive shaft. Limiting bars are fixed on both sides of the cavity cover. Through the mutual engagement of the limiting bars and the slide groove, the rising and falling of the stretching block are more stable. Through the reciprocating lifting motion of the stretching block and the staggering of the stretching components, the textile being transported inside the stretching chamber is repeatedly stretched in multiple sections and at multiple angles when passing through, thereby making the stretching of the textile more uniform and effectively improving the stretching effect.

[0025] 2. The textile stretching device and stretching method thereof fix a set of steam ironing components between the stretching components and stagger them one above the other. The connecting plate is suspended in the air inside the stretching chamber via a fixed shaft. When the servo motor is working, it drives the turntable and the connecting column on the turntable to rotate. The connecting column is connected to the drive slot. When the connecting column is rotated to the "12 o'clock" and "6 o'clock" directions, the connecting plate is in a vertical state. When the connecting column is rotated to the "3 o'clock" and "9 o'clock" directions, the steam ironing head has the maximum swing angle, so that the steam ironing head reciprocates back and forth with the fixed shaft as the center of the circle to iron the passing textile. Through the cooperation of the steam ironing component and the stretching component, the textile is heat-set and becomes smoother.

[0026] 3. The textile stretching device and stretching method thereof are as follows: before using the device, the entire textile roll is clamped and placed on a table, the operating window is opened, one end of the textile is first passed through the multiple components inside the stretching chamber, and then placed in the groove on the outer wall of the winding roller. The fixing clamp is rotated to connect it to the groove. Through the connection between the pin and the socket, the action of the spring, and the mutual connection between the arc block and the limit groove on the inner wall of the socket, one end of the textile is fixed inside the winding roller. When the winding motor is working and rotating, the textile is not easily loosened. BRIEF DESCRIPTION OF THE DRAWINGS
