Description

Technical Field

[0001] This invention belongs to the field of textile fabric equipment technology, specifically relating to a device for detecting the elasticity of textile fabrics. Background Technology

[0002] Weaving processes include machine weaving (also known as shuttle weaving), knitting, braiding, and nonwovens. Knitting is further divided into warp knitting and weft knitting. Warp knitting is a textile process belonging to the knitting field. It involves using one or more sets of parallel yarns fed into all the working needles of a machine in the warp direction to form loops simultaneously, thus creating a knitted fabric. This method is called warp knitting, and the resulting knitted fabric is called a warp-knitted fabric.

[0003] After production, warp-knitted fabrics need to be tested for elasticity. Generally, the rebound after stretching is used for testing. However, this method is not ideal and cannot accurately detect the actual elasticity of the fabric. Therefore, it is necessary to improve a new elasticity device for textile fabrics.

[0027] The pressing device 2 includes a top plate 21, two side support plates 22, two first electric telescopic rods 23, a pressure roller 24, a connecting plate 25, an auxiliary roller 26, a balance bar 27, and an angle sensor 29.

The two side support plates 22 are located on the left and right sides of the bottom of the top plate 21 and extend downward. The two first electric telescopic rods 23 are located on the sides of the two side support plates 22 and have their output ends facing downward. The output ends of the two first electric telescopic rods 23 are connected to bushings. The pressure roller 24 is connected to the two first electric telescopic rods 23 through bushings on both sides. One end of the two connecting plates 25 is connected to both sides of the pressure roller 24 and the two sides are coaxially connected. The connecting plate 25 and the rotating shaft of the pressure roller 24 are connected by bearings. The auxiliary roller 26 is connected between the two connecting plates 25 and is located at the rear end of the pressure roller 24, with the bottoms of the two plates being flush with each other.

[0028] The balance bar 27 is sleeved on one side of the shaft of the pressure roller 24, and the connection is made by bearing. A sleeve 28 is provided on one side of the rear end of the balance bar 27. The sleeve 28 overlaps with the top of the connecting plate 25 on one side. An angle sensor 29 is sleeved on the outside of the balance bar 27 and coaxially connected with the balance bar 27. The lifting device 3 includes a second motor 31, a second lead screw 32, two fixed plates 33 and two material support plates 35. The second motor 31 is set on the top of the fixed platform 1. The two fixed plates 33 are set vertically, and the top fixed plate 33 is connected to the bottom of the fixed platform 1. The bottom fixed plate 33 is in contact with the ground. The second lead screw 32 is set between the two fixed plates 33. The output end of the second motor 31 passes through the fixed platform 1 and is connected to the second lead screw 32. A lifting plate 34 is sleeved between the two lifting devices 3 on the same side. The lifting plate 34 is sleeved with the lead screw of the two lifting devices 3. The material support plate 35 is set on one side of the lifting plate 34 and is located at the bottom of one side of the material placement platform 4.

[0029] The receiving device includes a mounting base 51, a connecting rod 52, a supporting rod 53, and a slide rail 54. The mounting bases 51 are arranged in two groups facing each other on the top of the fixed platform 1. The connecting rod 52 is located on one side of the mounting base 51. The top of the supporting rod 53 is slidably sleeved on the other end of the connecting rod 52. The slide rail 54 is located on the top of the material placement platform 4 and is arranged corresponding to the two groups of mounting bases 51. The bottom of the supporting rod 53 and the slide rail 54 are slidably arranged relative to each other.

[0030] The principle of this invention: After the roll of fabric to be tested is sleeved on the surface of the two sleeve rods 52, the support sleeve rod 53 is slid forward through the slide rail 54 so that the top of the support sleeve rod 53 is sleeved with one end of the sleeve rod 52, thus providing support. Then, the handle 43 is pulled to push the material placement platform 4 under the fixed platform 1 through the bottom track 41. After the four corners of the bottom of the material placement platform 4 come into contact with the multiple lifting devices 3, the multiple second motors 31 are turned on. The two second motors 31 on the same side drive the second lead screw 32 at the output end to rotate. The lifting plate 34 connected between the two lead screws moves upward and lifts the material placement platform 4 upward through the material support plate 35 connected to one side. At this time, the material placement platform 4 extends to the top through the cavity 11 in the middle of the fixed platform 1.

[0031] At this time, the two sets of first electric telescopic rods 23 are activated. The first electric telescopic rods 23 drive the pressure rollers 24 connected to their bottoms to move downwards. At the same time, the electric sliders 14 connected to the bottom of both sides of the gantry frame 15 drive the gantry frame 15 to move along the direction of the first slide rail 13. At this time, the downward movement of the pressure rollers 24 will press down on the fabric sleeved on the surface of the two sleeve rods 52. At the same time, the gantry frame 15 moves forward, driving the pressure rollers 24 to move back and forth synchronously. When the pressure rollers 24 move back and forth, the auxiliary rollers 26 located at the rear end of the pressure rollers 24 will move back and forth as well. When the fabric is pressed down, the auxiliary roller 26 falls synchronously. After the pressure roller 24 moves forward, once the fabric rebounds, the auxiliary roller 26 will also rebound up and down. The top of one side of the auxiliary roller 26 is adjusted by the sleeve 28 and the balance bar 27. Since the sleeve 28 overlaps with the auxiliary roller 26, it will rebound up and down. The middle part of the balance bar 27 is connected to the angle sensor 29. When the sleeve 28 rotates at an angle, it will send a signal to the angle sensor 29, which is used to judge the rebound effect of the fabric after being pressed. Thus, the elasticity of the fabric can be judged by the back and forth rolling.

[0032] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and many variations are possible. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention should be considered within the protection scope of the present invention.
