Description

Technical Field

[0001] This invention relates to the field of fabric calendering technology, and more particularly to a calendering machine for treating mite-proof bedding fabric. Background Technology

[0002] In the textile dyeing and finishing industry, the calendering process is a key step in improving the appearance quality of fabrics. It involves pressing the fabric with high-temperature and high-pressure rollers to give it a lasting luster, a smooth hand feel, and stable dimensions. However, during the calendering process, especially when processing high-count, high-density, and functionally finished high-end fabrics (such as mite-proof bedding fabrics), longitudinal wrinkles (commonly known as "ruffles") are easily generated at the fabric edges due to uneven stress and drying shrinkage during the fabric feeding process.

[0003] During fabric conveying, the running path and stress state differ between the central area and the two side edges. Traditional widening devices are mostly integral or statically adjustable, making it difficult to accurately and independently compensate and control the real-time tension of the two side edges during dynamic operation. This results in the edge areas becoming loose or tight before entering the calendering rollers, thus forming wrinkles.

[0004] Before calendering, the entire fabric is often sprayed or steamed to soften the fibers and improve their plasticity. However, due to the edge effect of the equipment and airflow interference, the actual humidification effect in the selvage area is often weaker than that in the fabric body. This causes the fibers to exhibit different softening states in the selvage and fabric body. Under the high temperature and pressure of subsequent calendering, new stress wrinkles are generated due to the difference in shrinkage rate. Therefore, a calendering machine for treating mite-proof quilt fabrics is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the background art by proposing a calender for treating mite-proof bedding fabric.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A calender for treating mite-proof bedding fabric includes a base, two evenly distributed side plate frames fixed to the top of the base, an upper slider slidably connected inside the side plate frames, a lower slider disposed below the upper slider, the lower slider being fixed to the side plate frames, and pressure rollers rotatably connected between the two lower sliders and the two upper sliders. A steam cylinder is provided on one side of the side panel frame. A steam guide plate is fixed to the top of the steam cylinder. A second drive motor is fixed to one side of the steam cylinder. A fixed cylinder is fixed inside the second drive motor. A limit cover is provided on the top of the second drive motor. Water inlets are connected to both sides of the limit cover. Branch pipes are fixed to the bottom of both water inlets. Four sets of transverse anti-wrinkle mechanisms are provided between the fixed cylinder and the second drive motor. Each set includes an upper spiral gear groove assembly and a lower spiral gear groove assembly. The upper spiral gear groove assembly is fixedly connected to the second drive motor, and the lower spiral gear groove assembly is fixedly connected to the fixed cylinder. Sliding rods are slidably connected in the sliding grooves of the upper spiral gear groove assembly and the lower spiral gear groove assembly. One-way gears are fixedly connected to one side of each sliding rod. The two one-way gears are rotatably connected to the upper anti-wrinkle plate and the lower anti-wrinkle plate respectively through one-way bearings on the side away from the sliding rod. The top of the upper anti-wrinkle plate is slidably connected to the drive motor, and an internal slider is slidably connected inside the upper anti-wrinkle plate. A horizontal slider is slidably connected to the bottom of the lower anti-wrinkle plate, and the bottom of the horizontal slider is slidably connected to the fixed cylinder.

[0007] Preferably, both the internal slider and the transverse slider are internally threaded with bidirectional threaded rods, and the two bidirectional threaded rods are respectively rotatably connected to the drive motor and the fixed cylinder.

[0008] Preferably, a first shaft is fixed to one side of the two bidirectional threaded rods, the outer walls of the two first shafts are rotatably connected to the second drive motor, a third transmission wheel is fixed to the outer walls of the two first shafts, a second chain is sleeved on the outer walls of the two third transmission wheels, and a second gear is fixed to the end of one of the first shafts.

[0009] Preferably, each pair of transverse anti-wrinkle mechanisms is symmetrical with respect to the central axis of the fixed cylinder, and the two pairs of transverse anti-wrinkle mechanisms on the same side are arranged in a circumferential array.

[0010] Preferably, the outer walls of the two second gears mesh with the same first gear, the first gear is rotatably connected to the second drive motor via a shaft, and a transmission wheel is fixedly connected to the side of the first gear away from the second drive motor.

[0011] Preferably, each of the two lower sliders is provided with a second transmission wheel on the side away from the pressure roller. The second transmission wheel is fixedly connected to the pressure roller through a shaft. A first chain is sleeved between the second transmission wheel and the first transmission wheel.

[0012] Preferably, a humidification chamber is provided inside one side of the upper anti-wrinkle plate, a nozzle is connected to the bottom of the humidification chamber, and a connecting pipe is connected to the top of the humidification chamber. The connecting pipe is connected to the branch pipe through a flexible pipe.

[0013] Preferably, a side frame is fixedly connected to one side of the lower slider, and a one-way threaded rod is rotatably connected inside the side frame. The outer wall of the one-way threaded rod is threadedly connected to the upper slider and the lower slider. A drive motor one is provided on one side of the lower slider, and a drive motor two is provided on one side of the upper slider. Drive motor one and drive motor two are fixedly connected to the pressure roller through a set shaft. Drive motor one is fixedly connected to the side plate frame through a bracket, and drive motor two is fixedly connected to the upper slider through a bracket.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This invention utilizes the alternating and opposing movements of the upper and lower anti-wrinkle plates driven by a bidirectional threaded rod to create a continuous and dynamic lateral stretching effect on the fabric edge. The dynamic force is more effective than static expansion in releasing the longitudinal stress accumulated in the fabric before calendering, fundamentally preventing and eliminating the formation of edge wrinkles.

[0015] By using a steam guide plate and a limiting cover, residual steam passing through the fabric is condensed and recovered, converted into humidifying water. The recovered water is directed to the upper anti-wrinkle plates on both sides of the fabric's running path and sprayed directly onto the fabric edges. This effectively softens the fibers, significantly reduces their elastic modulus, making subsequent mechanical stretching easier and more efficient, and preventing brittle wrinkles caused by excessively dry edges.

[0016] After being evenly humidified and fully stretched, the fabric edge can enter the pressure roller for calendering in the best condition. This ensures the uniform distribution of calendering pressure and heat, effectively avoiding edge-to-center differences (such as uneven gloss and thickness) and permanent wrinkling defects caused by fabric edge wrinkles and uneven drying and wetting.

[0021] Reference Figure 1 - Figure 10 A calender for treating mite-proof bedding fabric includes a base 1, with two evenly distributed side plate frames 2 fixedly connected to the top of the base 1. An upper slider 13 is slidably connected inside the side plate frame 2, and a lower slider 16 is provided below the upper slider 13. The lower slider 16 is fixedly connected to the side plate frame 2, and pressure rollers 12 are rotatably connected between the two lower sliders 16 and the two upper sliders 13. A steam cylinder 3 is provided on one side of the side plate frame 2. A steam guide plate 20 is fixedly connected to the top of the steam cylinder 3. A second drive motor 18 is fixedly connected to one side of the steam cylinder 3. A fixed cylinder 23 is fixedly connected inside the second drive motor 18. A limiting cover 11 is provided on the top of the second drive motor 18. Water inlets 10 are connected to both sides of the limiting cover 11. Branch pipes 22 are fixedly connected to the bottom of both water inlets 10. Four sets of transverse anti-wrinkle mechanisms are provided between the fixed cylinder 23 and the second drive motor 18. Each set includes an upper spiral gear groove assembly 24 and a lower spiral gear groove assembly 25. The upper spiral gear groove assembly 24 is fixedly connected to the second drive motor 18, and the lower spiral gear groove assembly 25 is fixedly connected to the fixed cylinder 23. Sliding rods 33 are slidably connected in the sliding grooves of the upper spiral gear groove assembly 24 and the lower spiral gear groove assembly 25. One-way gears 27 are fixedly connected to one side of each sliding rod 33. The side of each one-way gear 27 away from the sliding rod 33 is rotatably connected to an upper anti-wrinkle plate 19 and a lower anti-wrinkle plate 31 through one-way bearings, respectively. The top of the upper anti-wrinkle plate 19 is slidably connected to the drive motor 18. An internal slider 28 is slidably connected inside the upper anti-wrinkle plate 19. A horizontal slider 32 is slidably connected to the bottom of the lower anti-wrinkle plate 31. The bottom of the horizontal slider 32 is slidably connected to the fixed cylinder 23.

[0022] Both the internal slider 28 and the transverse slider 32 are internally threaded with bidirectional threaded rods 26, and the two bidirectional threaded rods 26 are rotatably connected to the drive motor 18 and the fixed cylinder 23, respectively.

[0023] A side frame 14 is fixedly connected to one side of the lower slider 16. A one-way threaded rod 15 is rotatably connected inside the side frame 14. The outer wall of the one-way threaded rod 15 is threadedly connected to the upper slider 13 and the lower slider 16. A drive motor 4 is provided on one side of the lower slider 16, and a drive motor 18 is provided on one side of the upper slider 13. The drive motor 4 and the drive motor 18 are fixedly connected to the pressure roller 12 through a shaft. The drive motor 4 is fixedly connected to the side plate frame 2 through a bracket, and the drive motor 18 is fixedly connected to the upper slider 13 through a bracket.

[0024] In this embodiment, the fabric passes between the surface of the fixed cylinder 23 and the two upper anti-wrinkle plates 19, then passes through the steam guide plate 20, and after steam treatment, it is output through the calendering of the two pressure rollers 12. During the conveying process, the drive motor 1 4 and the drive motor 2 18 rotate in opposite directions. The drive motor 1 4 drives the drive wheel 1 6 and the first gear 7 to rotate through the drive wheel 2 17 and the chain 1 5. The rotation of the first gear 7 drives the two second gears 8 to rotate. The two second gears 8 drive the bidirectional threaded rod 26 to rotate through the first shaft 30, the drive wheel 3 21 and the chain 2 9. The rotation of the two bidirectional threaded rods 26 drives the upper anti-wrinkle plate 19 and the lower anti-wrinkle plate 31 to move through the internal slider 28 and the transverse slider 32.

[0025] The upper anti-wrinkle plate 19 has a humidification chamber 34 inside one side. The bottom of the humidification chamber 34 is connected to a nozzle, and the top of the humidification chamber 34 is connected to a connecting pipe 29. The connecting pipe 29 is connected to the branch pipe 22 through a flexible pipe.

[0026] In this embodiment, water is added into the limiting cover 11 through the water inlet 10, and the water enters the connecting pipe 29 through the branch pipe 22 and is sprayed out onto the edge of the fabric through the upper anti-wrinkle plate 19.

[0027] Among them, one side of the two bidirectional threaded rods 26 is fixedly connected to a first shaft 30, the outer wall of the two first shafts 30 is rotatably connected to the drive motor 18, the outer wall of the two first shafts 30 is fixedly connected to a transmission wheel 21, the outer wall of the two transmission wheels 21 is fitted with a chain 9, and the end of one of the first shafts 30 is fixedly connected to a second gear 8.

[0028] Each pair of transverse anti-wrinkle mechanisms is symmetrical with respect to the central axis of the fixed cylinder 23, and the two pairs of transverse anti-wrinkle mechanisms on the same side are arranged in a circular array.

[0029] The outer walls of the two second gears 8 are meshed with the same first gear 7. The first gear 7 is rotatably connected to the second drive motor 18 via a shaft. A transmission wheel 6 is fixed to the side of the first gear 7 away from the second drive motor 18.

[0030] Both lower sliders 16 are provided with a second transmission wheel 17 on the side away from the pressure roller 12. The second transmission wheel 17 is fixedly connected to the pressure roller 12 through a shaft. A chain 5 is sleeved between the second transmission wheel 17 and the first transmission wheel 6.

[0031] In this embodiment, the two sets of upper anti-wrinkle plates 19 and lower anti-wrinkle plates 31 on the same side are staggered. Since the one-way gear 27 is rotatably connected to the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 through the one-way bearing, when the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 move toward the middle of the fixed cylinder 23, the one-way gear 27 will drive the sliding rod 33 to move along the outside of the upper ring gear groove assembly 24 and the lower ring gear groove assembly 25, and the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 will move away from each other. When the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 move toward both sides of the fixed cylinder 23, the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 will move along the side of the upper ring gear groove assembly 24 and the lower ring gear groove assembly 25 closer to the fixed cylinder 23, so that the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 can stretch the fabric laterally and avoid wrinkles during calendering.

[0032] Steam passing through the fabric via the steam guide plate 20 is collected by the inner wall of the limiting cover 11, and water droplets flow down along the inclined surface inside, enter the connecting pipe 29, and are sprayed out at the edge of the fabric through the upper anti-wrinkle plate 19 to prevent them from escaping.

[0033] Working principle: Fabric such as Figure 10As shown, the fabric passes between the surface of the fixed cylinder 23 and the two upper anti-wrinkle plates 19, then through the steam guide plate 20. After steam treatment, it is output through the calendering of the two pressure rollers 12. Water is added into the limiting cover 11 through the water inlet 10. The water enters the connecting pipe 29 through the branch pipe 22 and is sprayed out onto the edge of the fabric through the upper anti-wrinkle plate 19. During the conveying process, the drive motor 1 4 and the drive motor 2 18 rotate in opposite directions. The drive motor 1 4 drives the drive wheel 1 6 and the first gear 7 to rotate through the transmission wheel 2 17 and the chain 1 5. The rotation of the first gear 7 drives the two second gears 8 to rotate. The two second gears 8 drive the bidirectional threaded rod 26 to rotate through the first shaft 30, the transmission wheel 3 21 and the chain 2 9. The rotation of the two bidirectional threaded rods 26 drives the upper anti-wrinkle plate 19 and the lower anti-wrinkle plate 31 to move through the internal slider 28 and the transverse slider 32.

[0034] The two sets of upper anti-wrinkle plates 19 and lower anti-wrinkle plates 31 on the same side are staggered. Since the one-way gear 27 is rotatably connected to the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 through the one-way bearing, when the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 move toward the middle of the fixed cylinder 23, the one-way gear 27 will drive the sliding rod 33 to move along the outside of the upper ring gear groove assembly 24 and the lower ring gear groove assembly 25, and the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 will move away from each other. When the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 move toward both sides of the fixed cylinder 23, the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 will move along the side of the upper ring gear groove assembly 24 and the lower ring gear groove assembly 25 closer to the fixed cylinder 23, so that the upper anti-wrinkle plate 19 and lower anti-wrinkle plate 31 can stretch the fabric laterally and prevent wrinkles from forming during calendering.

[0035] Steam passing through the fabric via the steam guide plate 20 is collected by the inner wall of the limiting cover 11, and water droplets flow down along the inclined surface inside, enter the connecting pipe 29, and are sprayed out at the edge of the fabric through the upper anti-wrinkle plate 19 to prevent them from escaping.

[0036] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
