Description

Technical Field

[0001] This application relates to the field of stenter technology, and more particularly to an adaptive exhaust system for stenters. Background Technology

[0002] Stenter machines are mainly used in the finishing process of textiles. By heating, stretching, and cooling the textiles, they bring them to the desired size, shape, and properties. During the stenting process, a large amount of heat is generated, so ventilation is required to remove it and avoid affecting the air quality in the workshop. The humidity and temperature inside the stenter also need to be maintained within a certain range. However, the current exhaust volume can only be manually adjusted, or it can only maintain a fixed air volume. Different fabrics and stenting processes have different requirements for the airflow and temperature distribution inside the stenter, which leads to turbulent airflow inside the stenter, affecting the uniform contact between the fabric and the hot air, and causing a waste of heat energy.

[0010] The exhaust pipe is equipped with a fume sensor.

[0011] In one embodiment, the sieving component further includes a cover plate, and a first filter plate, a second filter plate and a third filter plate are spaced apart on the cover plate.

[0021] The advantages or beneficial effects of the above technical solutions include at least the following:

[0022] This application discloses an adaptive exhaust system for a stenter. Through the installation of heating components and flow ports, the system heats the gas flowing between the machine and the heat-generating chamber to generate hot air. A first fan component in the ductwork assembly on the machine, working in conjunction with the main and auxiliary pipes, exhausts the heat from within the machine. Because the machine is equipped with differential pressure and temperature / humidity sensors, the system can monitor the temperature, humidity, and differential pressure, thereby adjusting the rotational power of the first fan component and thus the exhaust volume. Furthermore, because the main pipe has a receiving seat for a sieve component, the gas flowing towards the first fan component passes through a first, second, and third filter plate, achieving multiple filtration of the hot air, removing impurities and reducing environmental pollution. Through the coordination of the differential pressure, temperature / humidity, and first fan components, the system can adjust the exhaust volume according to the conditions within the machine, thus solving the problem that existing stenters can only provide fixed exhaust and lack flexibility.

[0042] Reference Figures 1-5 An adaptive ventilation system for a setting machine includes a machine base 1. A conveyor belt 11 is installed inside the machine base 1. The conveyor belt 11 is a conventional conveyor belt used to transport textiles requiring setting. Both ends of the conveyor belt 11 extend to the outside of both ends of the machine base 1. A heat-generating box 12 is installed at the bottom of the machine base 1. An air inlet window 121 is provided on the heat-generating box 12 to connect the inside of the heat-generating box 12 with the outside. An opening 122 is also provided on the heat-generating box 12, extending into the machine base 1 and fitted with... Equipped with a heating element 2, which uses an electric heating element in the prior art, the heat generation box 12 is also provided with a flow port 123 connected to the machine base 1. The opening 122 and the flow port 123 are located at the two ends of the heat generation box 12 respectively. Hot air enters the machine base 1 from the heat generation box 12 through the opening 122 and permeates from the bottom to the fabric on the conveyor belt 11. Combined with the return design of the flow port 123, a closed-loop hot air circulation is formed, which avoids the fabric deformation or color difference problem caused by local overheating in traditional setting machines.

[0043] The machine 1 is equipped with a differential pressure detection component 3 and a temperature and humidity detection component 4. The differential pressure detection component 3 is a differential pressure detector of the prior art, used to monitor the airflow resistance in the machine 1. The temperature and humidity detection component 4 is a temperature and humidity detector of the prior art, used to monitor the temperature and humidity in the machine 1. The power of the heating component 2 and the fan speed are dynamically adjusted according to the temperature and humidity data to ensure that the fabric is set under the best temperature and humidity conditions.

[0044] The machine 1 is also equipped with a duct component 5, which includes a main pipe 51 and a secondary pipe 52. One end of the secondary pipe 52 is connected to the main pipe 51, and the other end is connected to the interior of the machine 1. Several secondary pipes 52 are arranged at intervals. The main pipe 51 is connected to a first fan component 53. The first fan component 53 adopts an axial flow fan in the prior art. The exhaust pipe 531 is installed at the air outlet of the first fan component 53. The exhaust pipe 531 is used to exhaust the hot air that has been filtered after passing through the screening component 6. An oil fume sensing component 5311 is installed on the exhaust pipe 531. The oil fume sensing component 5311 can dynamically detect the concentration of oil mist particles in the exhaust gas. When the concentration exceeds the standard, an alarm is triggered or the fan speed is adjusted to avoid oil clogging the duct or polluting the environment.

[0045] The main pipe 51 is also equipped with a receiving seat 511, which has a cavity extending to the outside. A screening component 6 is movably installed in the cavity. The screening component 6 includes a first filter plate 61, a second filter plate 62, and a third filter plate 63 distributed at intervals. The first filter plate 61 is a coarse filter layer made of stainless steel mesh, the second filter plate 62 is a medium filter layer made of non-woven fabric, and the third filter plate 63 is a fine filter layer made of high-efficiency glass fiber filter paper. The generated smoke is filtered through different filter layers, and particles of different sizes are intercepted step by step, thereby reducing the harmfulness of the emitted smoke.

[0046] Based on the above structure, when the conveyor belt 11 moves the textile into the machine 1, the gas inside the machine 1 flows. Therefore, by activating the heating element 2, some of the gas passes through the opening 122 and is heated. Following the gas flow, it re-enters the machine 1 through the flow port 123 for hot air circulation. The ductwork component 5 on the machine 1 is used for exhaust ventilation, thus preventing excessively high temperatures inside the machine 1. Through the cooperation of the differential pressure detection component 3 and the temperature and humidity detection component 4, the differential pressure and temperature / humidity inside the machine 1 can be detected, thereby controlling the rotation speed of the first fan component 53 and adjusting the exhaust effect. Furthermore, the main pipe 51 used for smoke exhaust has a receiving seat 511 for installing the screening component 6. When the hot air from the machine 1 passes through the main pipe 51, it will be filtered by the first filter plate 61, the second filter plate 62 and the third filter plate 63 in the screening component 6, thereby removing impurities from the hot air and reducing the environmental impact caused by impurities after the hot air is discharged. With the cooperation of the differential pressure detection component 3 and the temperature and humidity detection component 4, the operator can accurately understand the situation inside the machine 1 and adjust the exhaust situation by adjusting the air intake of the first fan component 53. This solves the problem that the exhaust effect of the existing stenter is fixed, which makes it impossible to adjust according to the situation inside the machine 1 and causes heat energy waste.

[0047] In one embodiment, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 5 The sieving component 6 also includes a cover plate 64. The first filter plate 61, the second filter plate 62 and the third filter plate 63 are distributed on the cover plate 64 at intervals. When the first filter plate 61, the second filter plate 62 and the third filter plate 63 are located in the cavity, the cover plate 64 abuts against the top end face of the receiving seat 511. The top of the cover plate 64 is provided with a handle 641. The handle 641 is provided to facilitate the operator to hold it. By lifting the cover plate 64, the first filter plate 61, the second filter plate 62 and the third filter plate 63 can be inserted into or moved away from the cavity.

[0048] In one embodiment, reference is made to Figure 1 and Figure 3The heat generation box 12 is also equipped with a second fan component 124, which is a circulating fan in the prior art. The air inlet of the second fan component 124 faces the air inlet window 121, and the air outlet of the second fan component 124 covers the flow port 123, so that the external fresh air is drawn in from the air inlet window 121, preheated by the heating component 2, and evenly covers the inside of the machine 1, eliminating the problem of uneven heat zone caused by traditional natural convection. The air outlet covering the flow port 123 can prevent the hot and humid air in the machine 1 from flowing back into the heat generation box 12, thus extending the life of the heating component 2.

[0049] In one embodiment, referring to Figure 1-1, the opening 122 is also provided with a filter screen 1221. The filter screen 1221 is located between the heating component 2 and the machine base 1. The filter screen 1221 can block fibers and prevent dust from directly contacting the heating element, reduce the risk of carbon buildup, reduce fire hazards, and make the hot air circulating in the machine base 1 evenly distributed, thus improving the uniformity of airflow.

[0050] In one embodiment, reference is made to Figure 1 , Figure 4 and Figure 5 The bottom of the cover plate 64 is provided with several spaced mounting holes 642. The first filter plate 61, the second filter plate 62 and the third filter plate 63 are all provided with protrusions 65 that match the mounting holes 642. By embedding the protrusions 65 into the mounting holes 642, the first filter plate 61, the second filter plate 62 and the third filter plate 63 are installed on the cover plate 64. Specific filter plate combinations can be replaced according to different process requirements to achieve flexible configuration. Furthermore, the mechanical snap-fit ​​design between the protrusions 65 and the mounting holes 642 avoids filter plate displacement caused by vibration, thereby improving the flexibility of the screening component 6.

[0051] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 5 It also includes a host computer 7, which is a programmable controller in the prior art. The host computer 7 is communicatively connected to the differential pressure detection component 3, the temperature and humidity detection component 4, and the oil fume sensing component 5311. The host computer 7 is electrically connected to the first fan component 53 and the second fan component 124. The power of the heating component 2 can be adjusted by detecting the temperature and humidity through the temperature and humidity detection component 4. The degree of filter blockage is judged based on the oil fume sensing component 5311 and the differential pressure detection component 3. The dynamic data of the oil fume concentration is transmitted to the host computer 7. The host computer 7 controls the rotation speed of the first fan component 53 and the second fan component 124 to achieve multi-parameter collaborative control and complete adaptive exhaust operation.

[0052] In one embodiment, reference is made to Figure 1 and Figure 6Several air inlet windows 121 are provided and distributed at intervals within the heat generation box 12. The arrangement of several air inlet windows 121 can increase the amount of fresh air entering the heat generation box 12, increase the amount of fresh air introduced, and disperse the air inlet path to reduce local eddies. This ensures that even if a single window is accidentally blocked, the remaining windows can still maintain basic ventilation requirements and avoid production interruption.
