DETAILED DESCRIPTION

[0029] The technical solutions of the present application will be further described in detail below in combination with specific embodiments:

[0030] First embodiment

[0031] Please refer to the attached drawings Figure 1 - attached drawings Figure 10A wide-width detection device for jacquard textile fabric production includes a base plate 1, a support frame 12 is fixed on the base plate 1, a horizontal plate 13 is fixed on the support frame 12, a pair of winding rollers 2 are rotatably mounted on the base plate 1, fabric 3 is wound on the two winding rollers 2, and a marking belt 5 is arranged parallel to the bottom of the fabric 3, a support plate 20 for supporting the fabric 3 is fixed on the base plate 1, a turntable 7 is rotatably mounted on the horizontal plate 13, a lifting and pushing component is installed on the turntable 7, and a sliding frame I19 and a sliding frame II31 that are relatively set are slidably mounted on both sides of the horizontal plate 13, a horizontally extending pressing plate 16 is vertically slidably mounted on the sliding frame II31, and the pressing plate 16 corresponds to the lifting and pushing component. A return spring 32 is fixed between the sliding frame II31, an elastic component is installed between the sliding frame II31 and the support plate 20, the sliding frame I19 is in contact with the side of the fabric 3, a vertical plate 17 is fixed on the sliding frame I19, a guide sleeve 35 is slidably installed on the vertical plate 17, a horizontal spring I28 is fixed between the guide sleeve 35 and the vertical plate 17, a lifting plate 29 is vertically slidably installed on the guide sleeve 35, the lifting plate 29 is slidably connected to the sliding frame I19, a discharge pipe head 42 is installed at the lower end of the sliding frame I19, a marking component vertically corresponding to the marking tape 5 is installed on the discharge pipe head 42, and a moving conduction component for driving the sliding frame I19 to slide vertically is installed on the horizontal plate 13.

[0032] During the process of width detection of fabric 3 by this device, fabric 3 is clamped and limited in the width direction with the help of sliding frame I19 and sliding frame II31, so that sliding frame II31 and lifting plate 29 abut against the side of fabric 3, and then pigment marking is performed on marking belt 5 through marking component, and the edge position of fabric 3 is characterized by the position of the mark, thereby realizing width detection of specific position of fabric 3 and determining the degree of deviation of its width.

[0033] Among them, the elastic component includes a fixed block 33 fixed to the bottom of the support plate 20, a horizontal rod 54 is fixed on the fixed block 33, the sliding frame II31 is slidably sleeved on the horizontal rod 54, and a horizontal spring II34 is fixed between the sliding frame II31 and the fixed block 33. Under the elastic action of the horizontal spring II34, one side of the fabric 3 abuts against the sliding frame II31, ensuring that one side of the fabric 3 is limited first when testing.

[0034] The lifting and pushing assembly of this device includes a servo motor 6 fixed to a support frame 12. A bevel gear 11 is coaxially fixed to the output shaft of the servo motor 6 and the turntable 7. The two bevel gears 11 are meshed and connected. A vertical column 23 opposite to the pressure plate 16 is vertically slidably mounted on the horizontal plate 13. The vertical column 23 is connected to the turntable 7 through a connecting assembly. The connecting assembly includes a vertical sleeve 22 that is slidably sleeved on the vertical column 23. A circular frame 14 is fixed to the top of the vertical sleeve 22. A pin 21 eccentrically hinged to the turntable 7 is slidably mounted within the circular frame 14. A connecting spring 53 is fixed between the vertical sleeve 22 and the vertical column 23.

[0035] In addition, two winding rollers 4 located below the winding roller 2 are rotatably installed on the base plate 1, and the marking tape 5 is wound on the winding roller 4. A pulley mechanism II30 is connected between the winding roller 4 and the winding roller 2. A transmission gear 10 is coaxially fixed on the winding roller 2. An incomplete gear 9 intermittently meshed with the transmission gear 10 is rotatably installed on the base plate 1. The incomplete gear 9 is connected to the output shaft of the servo motor 6 through a pulley mechanism I8.

[0036] Through the above arrangement, when the servo motor 6 drives one of the bevel gears 11 to rotate, the bevel gear 11 drives the other bevel gear 11 to rotate. At this time, the turntable 7 rotates, and the turntable 7 drives the return frame 14 to move vertically through the pin 21. At this time, the return frame 14 drives the vertical column 23, the connecting spring 53 and the vertical column 23 to move downward, so that the vertical column 23 pushes the push plate 16 to move and press the fabric 3, ensuring that the position of the detection area of ​​the fabric 3 is stable when the fabric 3 is detected, thereby greatly improving the accuracy of wide-width detection.

[0037] The servo motor 6 drives the incomplete gear 9 via the pulley mechanism I8, which in turn intermittently drives the transmission gear 10, which in turn drives the winding roller 2. This allows the fabric 3 to rotate in a step-by-step manner, automatically adjusting the inspection position of the fabric 3. This eliminates the need to manually change the inspection position, thus achieving automated multi-point inspection of the fabric 3. As the winding roller 2 rotates, it drives the take-up roller 4 via the pulley mechanism II30. At this time, the marking tape 5 can be conveyed in a step-by-step manner, and the conveying of the marking tape 5 and the fabric 3 is synchronized, ensuring the accuracy of the marked position of the fabric 3 and improving the efficiency of wide-width inspection of the fabric 3.

[0038] The mobile transmission component of this device includes an intermediate gear 26 rotatably mounted on the horizontal plate 13. The upper and lower sides of the intermediate gear 26 are respectively engaged with a horizontally arranged spur rack I24 and a spur rack II25. The spur rack I24 is fixed to the vertical plate 17, and the spur rack II25 is slidably mounted on the horizontal plate 13. A transmission rod 15 is hinged between the spur rack II25 and the vertical sleeve 22. A wedge block 55 vertically corresponding to the lifting plate 29 is fixed on the vertical plate 17.

[0039] The vertical guide rod 41 is fixed on the guide sleeve plate 35, and the sleeve block 37 fixed on the lifting plate 29 is sleeved on the vertical guide rod 41, and the vertical spring I 36 is fixed between the sleeve block 37 and the guide sleeve plate 35.

[0040] Based on the above setting, after the vertical column 23 pushes the pressing plate 16 to press the fabric 3, the vertical sleeve 22 moves downward relative to the vertical column 23, the vertical sleeve 22 drives the straight rack II 25 to slide through the transmission rod 15, the straight rack II 25 drives the intermediate gear 26 to rotate, the intermediate gear 26 drives the straight rack I 24 to slide the vertical plate 17 towards the fabric 3, and finally the side wall of the lifting plate 29 abuts against the side of the fabric 3, realizing temporary clamping and limiting of the fabric 3 before width detection, and also realizing automatic adjustment of the position of the marking assembly.

[0041] During the sliding of the vertical plate 17, the wedge block 55 on the vertical plate 17 slides and pushes against the lifting plate 29, the lifting plate 29 moves vertically downward relative to the guide sleeve plate 35, so that the marking assembly can automatically move downward and perform marking detection on the marking tape 5. The above action process realizes vertical pressing, horizontal clamping and marking detection, greatly improving the width detection operation accuracy and automatic detection efficiency of the fabric 3.

[0042] Second embodiment

[0043] Please refer to the attached Figure 1 -attached Figure 10 On the basis of the first embodiment, in addition, as an improved scheme of the present application: the marking assembly includes a sleeve 44 fixed in the discharge pipe head 42, the discharge pipe 39 is sealingly and slidably installed in the sleeve 44, the side wall of the discharge pipe 39 is provided with a lateral hole 46, the spring ring 45 is fixed between the sleeve 44 and the discharge pipe head 42, the marking contact 43 is installed at the lower end of the discharge pipe 39, and the storage box 38 is installed at the bottom of the supporting plate 20, and the storage box 38 is communicated with the discharge pipe head 42 through the flow guide pipe 27.

[0044] In addition, the sliding ring 48 is slidably sleeved on the lifting plate 29, a pair of extension columns 50 are fixed on both sides of the sliding ring 48, the rotating arm 56 is rotatably installed on the extension column 50, the flattening roller 40 is rotatably installed at the lower end of the rotating arm 56, the baffle disc 51 is fixed at the end of the extension column 50, the torsional spring 52 is fixedly connected between the baffle disc 51 and the rotating arm 56, the connecting plate 49 is fixed on the lifting plate 29, and the vertical spring II 47 is fixed between the connecting plate 49 and the sliding ring 48.

[0045] During the vertical downward movement of the lifting plate 29, the leveling roller 40 first contacts the surface of the marking tape 5, and then under the connecting action of the rotating arm 56, the two leveling rollers 40 roll to both sides of the discharge pipe 39, and the L-shaped support plate 18 supports the marking tape 5 to achieve the leveling effect of the marking area of ​​the marking tape 5, thereby ensuring the marking effect of the subsequent marking contact 43.

[0046] Subsequently, as the marking contact 43 contacts the marking tape 5, the discharge tube 39 moves upward relative to the sleeve 44. When the lateral hole 46 is connected to the discharge tube head 42, the pigment inside the discharge tube head 42 enters the discharge tube 39 through the lateral hole 46. Ultimately, the pigment is marked on the marking tape 5 through the marking contact 43. When marking is in progress, the marking contact 43 releases pigment for marking, and when not marking, the marking contact 43 does not release pigment. This allows the marking contact 43 to automatically open and close during wide-width marking detection of the fabric 3, effectively improving the detection effect. The storage box 38 stores the pigment used for marking by the marking contact 43, and the pigment flows into the discharge tube head 42 along the guide tube 27 made of a flexible material.

[0047] In summary, the present invention uses the fabric 3 and the marking belt 5 to synchronously transport in parallel, uses the marking component to mark and detect the width of the fabric 3, drives the fabric 3 to be transported linearly in a step-by-step manner through the winding roller 2, and uses the mobile conductive component to realize the automatic downward movement of the marking component, so that the marking component can automatically detect different positions of the fabric 3 without the need to manually change the detection position, which greatly improves the efficiency of the wide-width detection operation of the fabric 3. In the present invention, during the process of marking and detecting the fabric 3, the pressing plate 16 can automatically move downward and press the fabric 3 to limit the position, and the sliding frame II31 and the lifting plate 29 can automatically clamp the fabric 3 in the width direction. With the help of the lifting and pushing component, the fabric 3 can complete the vertical pressing, horizontal clamping and detection marking actions during the step-by-step feeding process, which greatly improves the accuracy of the wide-width detection operation and the efficiency of automatic detection of the fabric 3.
