Description

Technical Field

[0001] This utility model relates to the field of fabric printing and dyeing technology, specifically a new type of fabric printing and dyeing machine with drying function. Background Technology

[0002] In the textile industry, dyeing and printing machines are used to dye and print fabrics. By attaching dyes or pigments to the surface of the fabric according to preset patterns and colors, the fabric is beautified and functionalized. Drying allows the dyes or pigments to be quickly cured on the fabric, ensuring the functionality of the dyeing and printing effect.

[0003] Existing fabric printing and dyeing machines on the market mainly consist of a printing and dyeing mechanism and a drying mechanism. The printing and dyeing mechanism comprises a dye supply device, printing rollers, and pressure rollers, while the drying mechanism mainly includes a hot air drying device that heats and dries the fabric surface with hot air. However, existing drying structures mostly use blowing air to dry single-layer fabrics, resulting in insufficient contact between the hot air and the fabric. This necessitates extending the drying time to achieve the desired drying effect, leading to decreased drying efficiency. Furthermore, temperature variations within the drying chamber and uneven airflow distribution result in varying drying temperatures at different locations on the fabric, indicating that drying uniformity needs improvement. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing fabric dyeing machines have low drying efficiency and long drying time for dyed fabrics, while the uniformity needs to be improved.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: This utility model proposes a novel fabric dyeing and printing machine with drying function, including a frame and a dyeing and printing structure and a transmission structure set on the frame. A hot drying chamber is provided on one side of the frame, and the hot drying chamber is divided into three drying chambers by two sets of vertically arranged partition plates. The three drying chambers are provided with auxiliary rollers at intervals. The two ends of the hot drying chamber are respectively provided with a fabric inlet and a fabric outlet. The hot drying chamber is provided with guide rollers at the fabric inlet and the fabric outlet. The partition plate is also provided with a fabric through-hole. During drying, the fabric is wound around the guide roller and the auxiliary roller and passes through the fabric through-hole to form a V-shaped travel path.

[0006] Hot air nozzles are installed on the bottom and top walls of the drying chamber relative to the auxiliary rollers. Multiple sets of hot air nozzles are evenly distributed along the width of the fabric to achieve uniform and efficient drying. Three sets of hot air blowers are installed on the top of the hot drying chamber. The three sets of hot air blowers are connected to the three sets of hot air nozzles in the drying chamber through hot air pipes. An infrared moisture sensor and an infrared temperature sensor are installed on one side of the partition plate above the fabric penetration.

[0007] Preferred technical solution 1: The transmission structure includes two sets of driving rollers rotatably mounted on the frame and multiple sets of driven rollers located between the two sets of driving rollers, and also includes a conveyor belt sleeved on the two sets of driving rollers. A drive motor is provided on one side of the frame and the power output shaft of the drive motor is connected to one end of a set of driving rollers through a coupling.

[0008] Preferred technical solution 2: The printing and dyeing structure includes multiple sets of printing roller seats arranged at intervals and symmetrically, a printing roller body rotating between two sets of printing roller seats, and a dye box located on one side of the frame. The dye box is equipped with a delivery pump, and the delivery end of the delivery pump is connected to the printing roller body through a pipe. The printing roller body and the driven roller are arranged vertically opposite each other to cooperate in roller printing.

[0009] Preferred technical solution 3: A controller is provided on the front side of the hot drying chamber, and the hot air blower, infrared moisture sensor and infrared temperature sensor are all electrically connected to the controller.

[0010] Preferred technical solution four: The auxiliary roller guides the fabric and makes it travel in a V-shaped path, and the hot air nozzle is set to correspond to the V-shaped opening of the fabric.

[0011] Preferred technical solution five: The front side of the hot drying chamber is also provided with a transparent observation window, and the upper part of the side wall of the hot drying chamber is provided with an exhaust gas outlet.

[0012] The present invention proposes a novel fabric dyeing and printing machine with a drying function. The beneficial effects achieved by adopting the above structure are as follows:

[0013] (1) By dividing the hot drying chamber into three independently temperature-controlled drying chambers (60-80℃→80-100℃→60-70℃) and coordinating with the fabric to travel in a V-shaped path, the effective drying journey and residence time of the fabric in the drying chamber are significantly extended. At the same time, multiple hot air nozzles are evenly distributed along the width of the fabric and correspond to the V-shaped opening to deliver air, avoiding local overheating caused by direct hot air blowing and ensuring that hot air penetrates the fabric evenly, thus achieving a high-efficiency and uniform drying effect and effectively solving the problems of long drying time and poor uniformity of traditional equipment.

[0014] (2) Infrared moisture sensors and infrared temperature sensors installed above the fabric entry points in each drying chamber monitor the humidity and temperature of the fabric in real time and feed the data back to the controller. The controller dynamically adjusts the output temperature of the corresponding hot air blower according to preset thresholds, realizing closed-loop intelligent control of the drying process. This stepped zone temperature control combined with real-time feedback adjustment can not only accurately match the temperature and humidity requirements of the fabric at each drying stage, avoiding over-drying or under-drying, but also effectively reduce energy consumption and improve energy utilization.

[0015] (3) The hot drying chamber, dyeing and printing structure and transmission structure are integrated on the frame. The layout is compact and reasonable. The V-shaped path design makes good use of space. The guide roller and auxiliary roller are used to achieve smooth transmission. The added high temperature observation window makes it easy to monitor the internal working conditions. The exhaust outlet is connected to the external treatment unit to facilitate environmentally friendly emissions. The overall structural design ensures efficient drying and dyeing quality, while also improving the ease of operation and environmental friendliness of the equipment. Attached Figure Description

[0024] Example 1

[0025] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A novel fabric printing and dyeing machine with drying function includes a frame 1 and a printing and dyeing structure and a transmission structure set on the frame 1. A hot drying chamber 2 is provided on one side of the frame 1, and the interior of the hot drying chamber 2 is divided into three drying chambers 4 by two sets of vertically arranged partition plates 3. The three drying chambers 4 are provided with auxiliary rollers 5 at intervals. The two ends of the hot drying chamber 2 are respectively provided with a fabric inlet 6 and a fabric outlet 7. The hot drying chamber 2 is provided with guide rollers 8 at the fabric inlet 6 and the fabric outlet 7. The partition plate 3 is also provided with a fabric through-hole. During drying, the fabric is wrapped around the guide roller 8 and the auxiliary roller 5 and passes through the fabric through-hole to form a V-shaped walking path. The front side of the hot drying chamber 2 is also provided with a transparent observation window. The observation window is made of high temperature resistant glass, and its edge is sealed with the hot drying chamber 2 by sealant. At the same time, the upper part of the side wall of the hot drying chamber is provided with an exhaust gas outlet, and the exhaust gas outlet is connected to the air inlet of an external exhaust gas treatment unit through a pipe.

[0026] like Figure 3 As shown, hot air nozzles 9 are installed on the bottom and top walls of the drying chamber 4, positioned opposite to the auxiliary rollers 5. Multiple sets of hot air nozzles 9 are evenly distributed along the fabric width to achieve uniform and efficient drying. Three sets of hot air blowers 10 are installed at the top of the drying chamber 2, each connected to one of the three sets of hot air nozzles 9 in the drying chamber 4 via hot air pipes. An infrared moisture sensor and an infrared temperature sensor are installed on one side of the partition plate 3 above the fabric penetration. The three sets of hot air blowers 10 and the drying chamber 4 are configured to create a stepped drying environment. The initial temperature of the drying chamber 4 is 60°C. The temperature of the drying chamber is -80℃, the temperature of the middle drying chamber 4 is 80-100℃, and the temperature of the end drying chamber 4 is 60-70℃. The temperature and humidity of the fabric drying process are detected by infrared moisture sensor and infrared temperature sensor. The detection data is transmitted to controller 18 through wires. Controller 18 feeds back the data to the corresponding hot air blower 10 according to the preset threshold to adjust the temperature. When the detected humidity is higher than the preset value, controller 18 controls hot air blower 10 to increase the output temperature; when the detected temperature is higher than the preset value, controller 18 controls hot air blower 10 to decrease the output temperature.

[0027] A controller 18 is located on the front side of the hot drying chamber 2. The hot air blower 10, infrared moisture sensor and infrared temperature sensor are all electrically connected to the controller 18.

[0028] The auxiliary roller 5 guides the fabric in a V-shaped path with an angle of 60-90 degrees. The hot air nozzle 9 is set to correspond to the V-shaped opening of the fabric to avoid direct hot air blowing and causing local overheating, thereby achieving uniform drying of the fabric by hot air.

[0029] Example 2

[0030] Based on Example 1, such as Figure 3 and Figure 4 As shown, the transmission structure includes two sets of driving rollers 11 rotatably mounted on the frame 1 and multiple sets of driven rollers 12 located between the two sets of driving rollers 11. It also includes a conveyor belt 13 sleeved on the two sets of driving rollers 11. A drive motor 14 is provided on one side of the frame 1, and the power output shaft of the drive motor 14 is connected to one end of a set of driving rollers 11 through a coupling, thereby driving the conveyor belt 13 to rotate.

[0031] The printing and dyeing structure includes multiple sets of printing roller seats arranged at intervals and symmetrically, a printing roller body 15 rotating between two sets of printing roller seats, and a dye box 16 located on one side of the frame 1. The dye box 16 is equipped with a delivery pump 17, and the delivery end of the delivery pump 17 is connected to the printing roller body 15 through a pipe. The printing roller body 15 and the driven roller 12 are arranged vertically opposite each other and cooperate in roller printing.

[0032] How to use a printing and dyeing machine

[0033] Step 1: Equipment preparation and fabric threading

[0034] The fabric to be printed is inserted into the inlet 6 of the hot drying chamber 2, passes through the inlet guide roller 8 and the auxiliary rollers 5 in each drying chamber 4 in sequence, and passes through the fabric penetration opening of the partition plate 3, and finally exits from the guide roller 8 of the outlet 7; ensuring that the fabric travels in a V-shaped path in the drying chamber 4, and that the surface of the fabric is tilted relative to the spray direction of the hot air nozzle 9.

[0035] Step 2: Start of printing and dyeing

[0036] Turn on the drive motor 14 to drive the active roller 11 and the conveyor belt 13 to rotate, so that the fabric passes through the printing and dyeing structure at a uniform speed; start the conveying pump 17 of the dye box 16 to deliver the dye to the printing roller body 15, and roll print the fabric through the cooperation of the printing roller and the driven roller 12.

[0037] Step 3: Step-by-step drying control

[0038] The controller 18 presets the stepped temperatures of the three drying chambers 4: initial chamber: 60-80℃ → intermediate chamber: 80-100℃ → end chamber: 60-70℃; the three hot air blowers 10 are started, and the hot air is delivered to the hot air nozzles 9 of the corresponding drying chambers 4 through the hot air pipes and sprayed evenly along the width of the fabric; the infrared moisture sensor detects the moisture content of the fabric in real time, the infrared temperature sensor monitors the surface temperature of the fabric, and the data is transmitted to the controller 18 in real time.

[0039] Step 4: Dynamic temperature control adjustment

[0040] When the sensor detects that the fabric humidity is higher than the preset threshold, the controller 18 automatically increases the output temperature of the corresponding hot air blower 10; when the fabric temperature is detected to exceed the safe value, the controller 18 immediately reduces the temperature of the hot air blower 10 to prevent overheating and damage to the fabric; the operating status of the fabric is monitored through a transparent observation window to ensure that there are no wrinkles or deviations.

[0041] Step 5: Exhaust Gas Treatment and Shutdown

[0042] The exhaust gas generated during the drying process is discharged through the exhaust gas outlet on the upper side wall of the hot drying chamber 2 and transported to the external exhaust gas treatment unit through pipelines; after the printing and dyeing is completed, the drive motor 14, the conveying pump 17 and the hot air blower 10 are turned off in sequence, and the power is cut off after the fabric is completely output.
