Description

Technical Field

[0001] This application relates to the field of textile machinery technology, and more specifically, to a fabric correction device for the feed inlet of a printing machine. Background Technology

[0002] As a key piece of equipment in the textile and apparel industry, the printing machine plays a core role in the printing process that enhances the added value of textiles. Its working principle is to transfer pre-designed patterns onto various fabrics through specific technologies, thereby achieving diversified and personalized decoration of the fabrics.

[0003] In the production process of a printing machine, the feed inlet is the first gate through which the fabric enters the equipment. Fabric wrinkling and deviation at the feed inlet is a common phenomenon. The main solution is to adjust the position of the rollers to regulate the working position of the fabric, thereby achieving the effect of fabric deviation correction.

[0004] Through long-term observation, it was found that when correcting the direction of a relatively smooth fabric, the insufficient friction between the fabric and the roller caused the fabric to slip while the roller moved, resulting in poor correction effect.

[0005] In view of this, we propose a fabric correction device for the feed inlet of a printing machine. Utility Model Content

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1-5This application discloses a fabric correction device for the feed inlet of a printing machine, comprising a printing machine 1, a rotating rod 2, a correction mechanism 3, and a fabric clamping mechanism 4. Two support frames A11 are fixedly connected to the inner wall of the printing machine 1. A roller shaft B21 is slidably connected to the middle of the two support frames A11. A clamping mechanism 4 is located below the roller shaft B21, used to drive the roller shaft B21 to slide axially and fix it. It is also located at the ends of the two support frames A11. The fabric clamping mechanism 4 includes a slidably disposed rubber column 41, which is driven by an external force to slide towards the roller shaft B21, used to cooperate with the roller shaft B21 to clamp and fix the fabric 100. A connecting ring 23 is fixedly connected to the outer wall of an adjusting ring 22, and the connecting ring 23 is fixedly connected to the rotating rod 2. A motor A is installed at the end of the rotating rod 2. Motor A is fixedly connected to square shaft A24. A base 12 is fixedly connected to the bottom of printing machine 1. A support leg 13 is fixedly connected to the bottom of support frame A11. A reinforcing member 14 is fixedly connected at the angle between support leg 13 and support frame A11. Roller shafts A15 are rotatably connected to the ends of the two support frames A11 for cooperating with roller shaft B21 to transport fabric 100. The correction mechanism 3 includes two mounting seats 31 fixed to the bottom of support frame A11. A rotating shaft 32 is rotatably connected inside the mounting seat 31. Two screw grooves 33 are opened in the middle of the rotating shaft 32. Two connecting plates 34 are threadedly connected to the rotating shaft 32 through the two screw grooves 33. The top of the connecting plate 34 is rotatably connected to the screw grooves 33. A limiting plate 35 is fixedly connected to the outer wall of the connecting plate 34. The limiting plate 35 is slidably set inside roller shaft B21.

[0030] The fabric cylinder needs to be installed at the end of the support frame A11. The fabric 100 is connected to the roller shaft B21 via roller shaft A15. The rotating rod 2 is driven by motor A to rotate, which in turn drives the roller shaft B21 to rotate, completing the fabric 100 conveying and printing process. When correction is required, the clamping mechanism 4 is used to press and fix the fabric. When the rotating shaft 32 of the correction mechanism 3 rotates under the action of motor B, the screw groove 33 drives the connecting plate 34 and the limiting plate 35 to slide axially, pushing the roller shaft B21 to move and adjust the position of the fabric 100 until correction is achieved. This step, together with the rubber column 41 moving closer to the position of the roller shaft B21, can activate the clamping effect, solving the problem of insufficient friction between the smooth fabric 100 and the roller shaft B21, which caused the fabric 100 to slip during subsequent correction, thus achieving a stable correction effect for the fabric 100.

[0031] Reference Figure 1 , Figure 2 and Figure 5The fabric clamping mechanism 4 also includes a support frame B42 fixed to the ends of two support frames A11. A movable groove A43 is provided in the middle of the support frame B42. Two electric push rods 44 are slidably connected to the inner wall of the movable groove A43. The output shafts of the two electric push rods 44 are fixedly connected to the rubber column 41. Two adjusting rings 22 are fixedly connected to the side wall of the roller B21. A square shaft A24 is fixedly connected to the end of the rotating rod 2. The square shaft A24 is slidably disposed inside the support frame A11. Two square shafts B45 are fixedly connected to the end of the rubber column 41. A chuck 46 is provided in the middle of the square shaft B45. The chuck 46 is located inside the adjusting ring 22 and is used to slide along with the roller B21. Movable grooves B47 are provided at both ends of the support frame B42. The square shafts B45 are slidably connected to the inner wall of the movable grooves B47. The square shafts B45 and the chuck 46 are rotatable. A smooth plate is provided on the surface of the chuck 46 corresponding to the adjusting ring 22.

[0032] When the fabric 100 needs to be clamped, the electric actuator 44 is activated, causing the electric actuator 44 of the fabric clamping mechanism 4 to extend and retract, driving the rubber column 41 to slide towards the roller shaft B21, thus clamping the fabric 100 in conjunction with the roller shaft B21. Meanwhile, the adjusting ring 22 holds the chuck 46 and slides synchronously with the roller shaft B21, ensuring the stability of clamping the fabric 100. Since the chuck 46 and the square shaft B45 are rotatably connected, the subsequent rotation of the adjusting ring 22 can push the chuck 46 to rotate. This step can achieve the clamping of the fabric 100. At the same time, the rubber column 41 makes flexible contact to avoid damaging the fabric 100. The chuck 46 and the adjusting ring 22 are adapted to ensure that the roller shaft B21 can move synchronously with the rubber column 41, thereby improving the stability of clamping the fabric 100. By rotating the chuck 46 and avoiding the action of the smooth plate, the contact wear between the chuck 46 and the adjusting ring 22 can be reduced.

[0033] Reference Figure 4 A fixing frame 341 is fixedly connected to the outer wall of the connecting plate 34, and a dustproof plate 342 is fixedly connected to the bottom of the fixing frame 341. The dustproof plate 342 has an arc-shaped structure and is located at the top of the screw groove 33. During the translation process of the connecting plate 34, the dustproof plate 342 can be moved, and the unfolded dustproof plate 342 can block the dust on the screw groove 33. This step can improve the cleanliness of the surface of the screw groove 33 and reduce the problem of jamming when the connecting plate 34 slides.

[0034] Reference Figure 3A sensor 16 is installed on the top of the support frame A11 to detect whether the fabric 100 is wrinkled. A mounting plate 17 is fixedly connected to the top of the support frame A11 by bolts to fix the sensor 16. An alarm 18 and a control module are fixed to the outer wall of the support frame A11. The sensor 16 and the alarm 18 are electrically connected to the control module. The sensor 16 (which emits a laser beam to illuminate the fabric surface, and the laser is captured by the receiver after being reflected by the fabric) monitors the flatness of the fabric in real time. When there are wrinkles in the fabric, the height difference between the raised part of the wrinkle and the flat part will cause the position of the reflected light to change. The sensor converts the height difference signal into an electrical signal. If a wrinkle is detected, the control module triggers the alarm 18 to remind manual intervention. This step avoids wrinkled fabric from entering the printing process by identifying fabric abnormalities in advance, thereby reducing the defect rate. The mounting plate 17 conveniently fixes the sensor, which is convenient for subsequent maintenance or replacement.

[0035] In summary, the fabric correction device at the inlet of the printing machine disclosed in this application requires the fabric 100 cylinder to be installed at the end of the support frame A11 during use. The fabric 100 is connected to the roller shaft B21 via roller shaft A15. The rotating rod 2 is driven by motor A to rotate, which in turn drives the roller shaft B21 to rotate, completing the fabric 100 conveying and printing process. When correction is required, the clamping mechanism 4 is used to press and fix the fabric 100. When the rotating shaft 32 of the correction mechanism 3 rotates under the action of motor B, the screw groove 33 drives the connecting plate 34 and the limiting plate 35 to slide axially, pushing the roller shaft B21 to translate and adjust the position of the fabric 100 until correction is achieved. When the fabric 100 needs to be clamped, the electric push rod 44 is activated. This causes the electric push rod 44 of the fabric clamping mechanism 4 to extend and retract, driving the rubber column 41 to slide towards the roller shaft B21, cooperating with the roller shaft B21 to clamp the fabric 100; while the adjusting ring 22 holds the chuck 46 and slides synchronously with the roller shaft B21 to ensure the stability of clamping the fabric 100. Since the chuck 46 and the square shaft B45 are rotatably connected, the adjusting ring 22 can push the chuck 46 to rotate when it rotates. During the translation process, the dust cover 342 can be moved, and the unfolded dust cover 342 can block the dust on the screw groove 33. The sensor 16 monitors the flatness of the fabric 100. If wrinkles are detected, the control module triggers the alarm 18 to remind manual intervention.
