Description

Technical Field

[0001] This utility model relates to the textile field, and in particular to a feeding mechanism for a winding machine. Background Technology

[0002] A winding machine is a piece of equipment specifically used in the textile industry. Its main function is to unwind yarn from bobbins and rewind it into cones for subsequent processing and use. The winding machine plays a crucial "bridge" role in textile production, serving as both the final step in spinning and the first step in weaving.

[0003] The basic function of a winding machine is to unwind yarn from an initial bobbin and guide it onto a new bobbin via components such as a yarn guide and a lead screw. This process ensures that the yarn maintains uniform tension and a neat shape during winding, thereby improving the efficiency and quality of subsequent processing.

[0004] During operation, workers typically place empty yarn bobbins on the winding rack of the winding machine. The winding machine simultaneously rotates a large number of yarn bobbins, drawing the yarn from multiple yarn tubes onto the bobbins. Once the bobbins are fully wound with yarn, the workers remove them from the winding rack and replace them with new bobbins. However, the winding machine has a large number of yarn bobbins, and the weight increases when the bobbins are fully wound. Therefore, it takes workers a lot of time and effort to remove the yarn bobbins. Utility Model Content

[0005] The purpose of this invention is to provide a feeding mechanism for a winding machine to solve the above-mentioned problems.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A feeding mechanism for a winding machine includes a winding machine with a row of take-up frames. Each take-up frame has a clamping mechanism. The winding machine is located behind the take-up frames and is fixedly connected to a base. A row of slide rails is fixedly connected to the base, sliding close to the take-up frames, with each slide rail corresponding to one of the take-up frames. A support plate is fixedly connected to the upper part of the base. The slide rails are located between the support plate and the take-up frames. Synchronous pulleys are rotatably connected to both ends of the support plate on the side of the base. A transmission belt is positioned between two synchronous pulleys and wraps around the support plate. One of the transmission belts is connected to a motor. A collection box is placed below one end of the support plate.

[0008] Using the above technical solution, when placing an empty yarn bobbin on each winding rack, a portion of the yarn from the yarn tube is first wound around the outer wall of the empty yarn bobbin. Then, the empty yarn bobbin is fixed to the winding rack by a clamping mechanism. The winding machine drives the empty yarn bobbins on each winding rack to rotate, concentrating the yarn from multiple yarn tubes onto one yarn bobbin. When the yarn bobbin is fully wound with yarn, the winding machine stops working, and the clamping mechanism on the winding rack releases the yarn bobbin. The yarn bobbins fully wound with yarn on each winding rack roll into the slide rail. Then, a new yarn bobbin is placed on the winding rack, and the yarn bobbins on the slide rail roll onto the transmission belt on the support plate. The motor drives the transmission belt to rotate through the synchronous pulley. The transmission belt transports the yarn bobbins fully wound with yarn to the far end of the support plate. The yarn bobbins fall from the end of the support plate into the collection box. Only the empty yarn bobbins need to be placed on the winding machine; there is no need to remove each yarn bobbin with yarn wound on it, saving physical strength and workload.

[0009] Preferably, a baffle is fixedly connected to the side of the support plate away from the winding frame of the winding machine, and the upper part of the baffle is inclined and the lower part is vertical.

[0010] The above technical solution is used to prevent the yarn bobbin from falling off the side of the drive belt when it slides down or during transportation.

[0011] Preferably, the winding frame includes a U-shaped rotating frame, which is rotatably connected to the winding machine. A turntable is rotatably connected to one side of the rotating frame, and a guide rod passes through the other side of the rotating frame. The guide rod is slidably connected to the rotating frame. A turntable is rotatably connected to the end of the guide rod located between the two sides of the rotating frame. A protrusion is fixedly connected to one end of the guide rod located on the outer side of the rotating frame. A push rod and a cylinder are hinged to the side of the winding frame where the guide rod is located. The push rod has a waist-shaped groove, and the protrusion of the guide rod is embedded in the waist-shaped groove of the push rod. The end of the cylinder output shaft is hinged to the push rod.

[0012] Using the above technical solution, when the empty yarn bobbin is placed on the take-up frame, the cylinder pushes the push rod to rotate. The push rod, through the waist-shaped groove and protrusion, drives the guide rod to move. The guide rod drives the second turntable to rotate and move away from the first turntable. The empty yarn bobbin is placed between the two turntables, with its two ends aligned with the first and second turntables respectively. The cylinder drives the push rod to rotate back. The push rod, through the guide rod, drives the second turntable to abut against one end of the yarn bobbin, and the first turntable to abut against the other end of the yarn bobbin, thus fixing the yarn bobbin on the take-up frame. Similarly, when the yarn bobbin is fully wound with yarn, the cylinder pushes the push rod to rotate. The push rod, through the guide rod, drives the second turntable to separate from the yarn bobbin. The yarn bobbin falls off the take-up frame, rolls into the slide, and then moves from the slide onto the transmission belt.

[0013] Preferably, a brush is fixedly connected to the base below the transmission belt, and the brush is in contact with the surface of the transmission belt.

[0014] Using the above technical solution, the transmission belt moves past the brush, and the brush removes the lint from the yarn on its surface.

[0015] Preferably, the surface of the transmission belt is provided with anti-slip ridges. Attached Figure Description

[0024] See Figures 1 to 6A feeding mechanism for a winding machine 1 is provided, comprising a winding machine 1, a row of take-up frames on the winding machine 1, a grooved tube installed below the winding frames, and a bobbin frame below the grooved tube for placing yarn tubes. The take-up frames include a U-shaped rotating frame 9, which is rotatably connected to the winding machine 1. A turntable 10 is rotatably connected to one side of the rotating frame 9, and a guide rod 11 passes through the other side of the rotating frame 9. The guide rod 11 is slidably connected to the rotating frame 9. A second turntable 12 is rotatably connected to the end of the guide rod 11 located between the two sides of the rotating frame 9. A retaining edge is integrally formed on the edge of the first turntable 10 and the second turntable 12. When the two turntables clamp the two ends of the yarn tube, the end of the retaining edge is embedded inside the retaining edge of the turntable, thereby preventing the yarn tube from falling off the turntable. A protrusion 13 is fixedly connected to one end of the guide rod 11 on the outer side of the rotating frame 9. A push rod 14 and a cylinder 15 are hinged to the side of the take-up frame where the guide rod 11 is located. The push rod 14 has a waist-shaped groove 16, and the protrusion 13 of the guide rod 11 is embedded in the waist-shaped groove 16 of the push rod 14. The end of the output shaft of the cylinder 15 is hinged to the push rod 14. The winding machine 1 is located behind the take-up frame and is fixedly connected to a base. A row of slide rails 2 is fixedly connected to the base, and each slide rail 2 is opposite to each take-up frame. A support plate 3 is fixedly connected to the upper part of the base. The slide rails 2 are located between the support plate 3 and the take-up frame. Synchronous winding machines are rotatably connected to both ends of the support plate 3 on the side of the base. A transmission belt 5 is installed between two synchronous pulleys 4. The transmission belt 5 is wrapped around the support plate 3. The surface of the transmission belt 5 is provided with anti-slip ridges to increase the friction between the transmission belt and the yarn bobbin and yarn, so as to better transport the yarn. A baffle 8 is fixedly connected to the side of the support plate 3 away from the winding frame of the winding machine 1. The upper part of the baffle 8 is inclined and the lower part is vertical. One of the transmission belts 5 is connected to a motor 6. A brush 17 is fixedly connected to the base below the transmission belt 5. The brush 17 is in contact with the surface of the transmission belt 5. When the transmission belt 5 moves past the brush 17, the brush 17 will brush off the lint of the yarn on its surface. A collection box 7 is placed below one end of the support plate 3.

[0025] Working principle: When an empty yarn bobbin is placed on each take-up frame, part of the yarn on the yarn tube in the bobbin frame is first wound onto the bobbin. Then, cylinder 15 pushes push rod 14 to rotate. Push rod 14, through waist-shaped groove 16 and protrusion 13, drives guide rod 11 to move. Guide rod 11 drives turntable 2 12 to rotate and move away from turntable 1 10. The empty yarn bobbin is placed between the two turntables, with its two ends aligned with turntable 1 10 and turntable 2 12 respectively. Cylinder 15 drives push rod 14 to rotate back. Push rod 14, through guide rod 11, drives turntable 2 12 to abut one end of the yarn bobbin, and turntable 1 10 to abut the other end of the yarn bobbin, thus fixing the yarn bobbin on the take-up frame. Then, rotating frame 9 is rotated, causing the yarn bobbin to contact the grooved tube. The grooved tube drives the yarn bobbin to rotate, winding all the yarn on the yarn tube in the bobbin frame onto its upper part. When the yarn bobbin is fully wound with yarn, the winding machine 1 stops working. The cylinder 15 pushes the push rod 14 to rotate. The push rod 14 drives the turntable 12 to separate from the yarn bobbin through the guide rod 11. The yarn bobbins with full yarn on each winding rack roll into the slide rail 2. Then, a new yarn bobbin is placed on the winding rack. The yarn bobbins on the slide rail 2 roll onto the transmission belt 5 on the support plate 3. The motor 6 drives the transmission belt 5 to rotate through the synchronous pulley 4. The transmission belt 5 transports the yarn bobbins with full yarn to the far end of the support plate 3. The yarn bobbins fall from the end of the support plate 3 into the collection box 7. Only empty yarn bobbins need to be placed on the winding machine 1. There is no need to remove each yarn bobbin with yarn one by one, which saves physical strength and work intensity.
