Technical Field

[0001] This utility model relates to the field of calendering technology, specifically a pressure-adjustable three-roll calendering machine. Background Technology

[0002] Textile fabrics are classified into two categories according to their weaving methods: weft-knitted fabrics and warp-knitted fabrics. Weft-knitted fabrics are often made from low-elastic polyester yarn or profiled polyester yarn, nylon yarn, cotton yarn, wool yarn, etc., and are woven on various weft knitting machines using plain knit, modified plain knit, rib plain knit, double rib plain knit, jacquard, terry, etc. Calcining machines are required for the deep processing of textile fabrics.

[0003] Traditional calendering machines typically employ mechanical manual screw pressure adjustment mechanisms or single-point hydraulic cylinders, which suffer from pressure response lag and insufficient synchronous adjustment precision, leading to fabric defects and affecting fabric processing quality. Therefore, a pressure-adjustable three-roll calendering machine is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a pressure-adjustable three-roll calender to solve the problems mentioned in the background art, where traditional calendering equipment typically uses a mechanical manual screw pressure adjustment mechanism or a single-point hydraulic cylinder, which suffers from pressure response lag and insufficient synchronous adjustment accuracy, leading to fabric defects and affecting the quality of fabric processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure-adjustable three-roll calender, comprising...

[0006] The base has brackets fixedly connected to both ends of its top, and an adjustment component is provided between the two brackets.

[0007] The adjustment assembly includes a slide block, two limiting plates, and two connecting rods. Two sliding grooves are formed on one side of each of the two supports. The slide block is slidably connected to the inside of the sliding grooves. The two limiting plates are fixedly connected to both sides of the slide block. One end of each connecting rod is mounted on both sides of the limiting plates. A fixed seat is hinged to one adjacent end of each connecting rod on one side. Guide posts are fixedly connected to both sides of the supports. A connecting seat is movably sleeved on the outer side of each guide post. One end of the connecting seat is fixedly connected to one side of the fixed seat. A roller mounting shaft is rotatably connected inside the slide block and the limiting plates.

[0008] Preferably, a double-piston rod hydraulic cylinder is installed on the opposite side of each of the two aforementioned supports, with both ends of the double-piston rod hydraulic cylinder being fixedly connected to one side of each of the two connecting seats.

[0026] Example

[0027] Please see Figure 1-5 This utility model provides a technical solution: a pressure-adjustable three-roll calender, including a base 1, with brackets 2 fixedly connected to both ends of the top of the base 1, and an adjustment component provided between the two brackets 2.

[0028] By setting an adjustment component, the fabric pressure can be adjusted to facilitate fabric processing. Simultaneous adjustment of the distance between the two rotating rollers 11 and the fixed roller 15 improves the processing accuracy of the device. The adjustment component includes a slide block 4, two limiting plates 5, and two connecting rods 6. Two sliding grooves 3 are provided on one side of each of the two supports 2. The slide block 4 is slidably connected inside the sliding grooves 3. The two limiting plates 5 are fixedly connected to both sides of the slide block 4. One end of each connecting rod 6 is installed on both sides of the limiting plates 5. Mounting seats are installed on both sides of the limiting plates 5. One end of each connecting rod 6 is installed inside the mounting seat. A fixed seat 7 is hinged to the adjacent ends of two connecting rods 6 on one side. Guide columns 8 are fixedly connected to both sides of the supports 2. A connecting seat 9 is movably sleeved on the outer side of the guide column 8. One end of the connecting seat 9 is fixedly connected to one side of the fixed seat 7. The slide block 4 and the limiting plates... The mounting shaft of the rotating roller 11 is rotatably connected inside the bracket 5. A double piston rod hydraulic cylinder 10 is installed on the opposite side of each of the two brackets 2. The two ends of the double piston rod hydraulic cylinder 10 are fixedly connected to one side of the two connecting seats 9. The two double piston rod hydraulic cylinders 10 can be controlled by an electro-hydraulic servo valve to ensure that the piston rods of the two double piston rod hydraulic cylinders 10 can extend and return synchronously. A fixed roller 15 is rotatably connected between the two brackets 2 and is located between the two rotating rollers 11. The piston rod of the double piston rod hydraulic cylinder 10 drives the connecting seat 9 to move outside the guide column 8. At this time, the connecting seat 9 drives the other end of the connecting rod 6 to move, so that the other end of the two connecting rods 6 pushes the limiting plate 5 to move on one side of the bracket 2. The limiting plate 5 then drives the slide 4 to move inside the slide groove 3, thereby adjusting the distance between the rotating roller 11 and the fixed roller 15 and completing the adjustment of the fabric pressure.

[0029] To ensure the smooth movement of the limiting plate 5, connecting blocks 12 are fixedly connected to both the upper and lower sides of the slide groove 3 on the base 1. Two slide rods 13 are fixedly connected between the connecting blocks 12. The limiting plate 5 is movably sleeved on the outside of the two slide rods 13. When the limiting plate 5 moves, the limiting plate 5 moves outside the two slide rods 13, and the connecting blocks 12 can limit the limiting plate 5.

[0030] To prevent wrinkles during fabric processing, a fixed frame 16 is fixedly connected to one side of each of the two brackets 2. A slider 17 is slidably connected to the inner side of each of the two fixed frames 16. A tension roller 18 is rotatably connected between the two sliders 17. An electric push rod 19 is installed at one end of each of the two fixed frames 16. The push rod of the electric push rod 19 passes through one end of the fixed frame 16 and is fixedly connected to one end of the slider 17. When it is necessary to adjust the tension of the fabric, the push rod of the electric push rod 19 is reset by the switch group. The push rod of the electric push rod 19 drives the slider 17 to move inside the fixed frame 16, so that the two sliders 17 drive the tension roller 18 to move. The tension roller 18 can pull the fabric to move, so as to adjust the tension of the tension roller 18.

[0031] A reduction motor 14 is installed on one side limit plate 5. The output shaft of the reduction motor 14 is fixedly connected to the mounting shaft of the rotating roller 11. When processing the fabric, the output shaft of the reduction motor 14 drives the mounting shaft of the rotating roller 11 to rotate, thereby processing the fabric.

[0032] Working principle or structural principle: When the pressure of the calender needs to be adjusted, the piston rod of the double piston rod hydraulic cylinder 10 is reset by controlling the switch group. The piston rod of the double piston rod hydraulic cylinder 10 drives the connecting seat 9 to move outside the guide column 8. At this time, the connecting seat 9 drives the other end of the connecting rod 6 to move, so that the other end of the two connecting rods 6 pushes the limiting plate 5 to move on one side of the bracket 2. The limiting plate 5 then drives the slide 4 to move inside the slide groove 3, thereby adjusting the distance between the rotating roller 11 and the fixed roller 15, adjusting the pressure on the fabric to facilitate fabric processing. Moreover, the synchronous adjustment of the distance between the two rotating rollers 11 and the fixed roller 15 can improve the processing accuracy of the device. When the tension of the fabric needs to be adjusted, the push rod of the electric push rod 19 is reset by controlling the switch group. The push rod of the electric push rod 19 drives the slider 17 to move inside the fixed frame 16, so that the two sliders 17 drive the tension roller 18 to move. The tension roller 18 can pull the fabric to move, so as to adjust the tension of the tension roller 18 and prevent wrinkles from occurring during fabric processing.
