Description

Technical Field

[0001] The utility model relates to the technical field of drying lines, and specifically discloses a mesh belt type drying line. Background Art

[0002] Printing and dyeing, also known as dyeing and finishing, is a processing method, and is also a general term for pre-treatment, dyeing, printing, finishing, washing, etc. After printing and dyeing, hot air is usually passed into the fabric to evaporate and take away the moisture in the fabric. However, since the fabric contains more moisture after printing and dyeing, a large amount of mist will be generated during drying. The discharged mist still contains a lot of heat, and the heat cannot be fully utilized, resulting in energy waste. In addition, during the drying process of the fabric, a single hot air drying method is used, and the fabric cannot be dried efficiently and fully, which prolongs the drying time and reduces the drying time. At the same time, the residual shrinkage of the same fabric is difficult to unify, which is not conducive to the later shaping process. For this reason, we need a mesh belt drying line.

The second material car 15 is located at the lower end of the cloth inlet assembly 12. The whole box feeding port of the mesh belt drying line is provided with a cloth inlet assembly 12, and a conveyor mesh belt 8 is installed on the right side of the cloth inlet assembly 12. The cloth inlet assembly 12 is provided with a cloth lifting roller and a wave-making roller. The fabric passes through the wave-making roller and enters the conveyor mesh belt 8 and is sent into the drying oven 9, so that the fabric forms a regular wavy state and is absolutely relaxed in the mesh belt; the whole box discharging port of the mesh belt drying line is provided with a cloth discharging rack 10, and a cooling plate 17 is arranged below the cloth discharging rack 10. The cloth discharging rack 10 is connected to the upper right side with a cloth discharging assembly 13, and the cloth discharging assembly 13 includes a cloth lifting roller and a swing device, and an exhaust duct 11 is arranged above each section of the mesh belt drying line, and the exhaust duct 11 is connected to the exhaust fan, and a stacking car 18 is arranged below the cloth discharging assembly 13.

[0016] The cooling plate 17 is a fabric cooling zone, which allows the fabric to be cooled before it is discharged and piled up, and falls on the fabric cart without tension and fluffy swing.

[0017] The oven 9 is provided with an inner filter plate 16 .

[0018] Among them, several nozzles are arranged between the upper and lower mesh belts in the six groups of single-section ovens 9, and the height of the upper nozzle can be adjusted to ensure that the fabric passes through the oven in the best form; the nozzles are arranged crosswise and connected to the fan 19 through pipelines.

[0019] Among them, the fan 19 adopts a high-efficiency energy-saving circulating fan, which meets the first-level energy consumption standard. The IE3 permanent magnet motor can effectively save energy by 10%, and the rated power is 30 kilowatts.

[0020] It should be noted that the whole box feeding port is provided with a cloth feeding assembly 12, on which are provided a cloth lifting roller and a wave-making roller. The fabric passes through the wave-making roller and enters the mesh belt and is sent into the drying oven 9, so that the fabric can form a regular wavy state and be absolutely relaxed in the mesh belt, which helps the fabric to shrink.

[0021] The whole box discharge port is provided with a cloth discharge rack 10, and the cloth discharge assembly 13 includes a cloth lifting roller and a swing device. The inclined cooling wooden slats are the fabric cooling area, so that the fabric can be cooled before the cloth is discharged and piled up, and the tension-free and fluffy swing falls on the cloth cart.

[0022] The whole box is composed of six groups of single-section ovens 9 and two groups of vibration boxes. Each single-section box is equipped with an inspection door on the upper side, and the door is equipped with an anti-scalding handle, which is safe and reliable. Each section of the box is equipped with an exhaust duct 11, and the exhaust duct 11 is connected to the exhaust fan. The lower side of each box is equipped with a filter device and an air supply duct. Each air supply duct is connected to its own air supply fan 19, and a heating device is provided in the duct. The circulating fan is controlled by variable frequency, and the temperature of each section of the oven can be automatically controlled. By changing the inlet and outlet air volume, it is used to adjust the temperature and humidity in the box. When the value reflected by the box temperature sensor or humidity sensor is too high or too low, the fan can adjust the working state at any time. When the temperature is too low, the hot air delivery to the box from the bottom is increased, and when the temperature or humidity is too high, the exhaust from the top is increased.

[0023] Two layers of Teflon conveyor belts 8 are installed in the whole box, which move the fabric in absolutely loose and regular wavy state between the two layers of belts from the box inlet to the box outlet. The belt can automatically tighten, automatically correct deviation, and alarm for faults. The correction adopts pneumatic control, which is stable and reliable to use. The extra-wide conveyor belt can run single or multiple fabrics at the same time, with high efficiency.

[0024] In the six groups of single-section ovens 9, each of the upper and lower mesh belts has several nozzles arranged between the belt layers, and the height of the upper nozzle can be adjusted to ensure that the fabric passes through the oven in the best form; the nozzles are arranged crosswise and connected to the fan through pipelines. Through the cooperation of the nozzles and the mesh belts, the box uses a multi-directional hot air flow to beat and oscillate the fabric to dry it, so that the fabric can achieve the warp and weft shrinkage effect and return the fabric to its original shape as much as possible; the fan 19 uses a high-efficiency energy-saving circulating fan, which meets the first-level energy consumption standard. The IE3 permanent magnet motor can effectively save 10% energy and has a rated power of 30 kilowatts.

[0025] A vibration box is installed between the 3rd to 4th single-section boxes and the 4th to 5th single-section boxes, which is used to beat the mesh belt. When the vibration rod rotates at high speed, it beats the mesh belt to vibrate, causing the fabric to produce sinusoidal oscillations, making appropriate moisture regain and accelerating pre-shrinkage of the fabric, thereby ensuring that the fabric reaches the best shrinkage and relaxation state on the oven mesh belt.

[0026] A corrugated plate is provided on the wall of the box, which is connected to the triangular water trough at the bottom of the box. The triangular water trough is connected to the water tank through a pipe. The mass of the liquid attached to the surface of the corrugated plate increases with the amount of accumulated liquid. Then the liquid drops into the triangular water trough, and then flows into the water tank through the reflux pipe for centralized collection and discharge.

[0027] Oven working process: the wave-making roller device is introduced into the net belt inside the oven → when the cloth passes through the oven, it will shrink and dry under the action of high-temperature circulating hot air and oscillating throwing → after cooling → the cloth is introduced into the cloth rack → swung out of the car.

[0028] Through the action of the conveying mesh belt 8 and the high-efficiency centrifugal fan 19, various circular knitted fabrics and flat-width woven fabrics can be pre-shrinked and dried. The material is laid evenly on the mesh belt in a wavy shape, and the mesh belt and the fabric are dragged forward in the box by the transmission device. The hot air flows through the fabrics, and the water vapor is discharged from the moisture-removing holes of the fabrics, thereby achieving the purpose of drying. The dried fabrics have a good feel, reduced internal stress, and reduced residual shrinkage, which is convenient for the shaping process.

[0029] The fabric is supported up and down by two mesh belts in a wavy and tension-free state. The overfeed size of the feed port can be adjusted according to the required pre-shrinkage. The advanced aerodynamic design concept and high-performance upper and lower alternating nozzles blow hot air from a series of air holes to oscillate the fabric surface alternately up and down, so that the fabric obtains a good flipping effect, ensuring that the fabric obtains the best shrinkage rate and soft feel.
