Abstract

This invention discloses a low-energy post-processing machine production equipment, relating to the field of fiber cloth production technology. The equipment includes a winding and unwinding mechanism, a desizing mechanism, an impregnation roller, and a drying mechanism arranged in sequence. The desizing mechanism is equipped with a waste heat recovery mechanism. The waste heat recovery mechanism sends the waste heat airflow from desizing through dust removal and heat exchange into a tank. The inner sleeve and partition plate form a multi-layer flow channel. When the air volume is small, the airflow is direct. When the air volume is large, it overflows into the flow channel of the next layer and passes through the heat storage unit. The heat is stored by the phase change material in the spiral heat conduction pipe. Then, the airflow is output by turning on the air pressure switch. Subsequently, the airflow mixes with cold air through the S-shaped flow channel of the temperature control unit for precise temperature control. Finally, the airflow flows to the fiber cloth through the preheating hood for pre-drying. Finally, it is cured non-contactly by the infrared radiation heating plate.

Description

Technical Field

[0001] This invention relates to the field of fiber cloth production technology, specifically a low-energy post-processing machine production equipment. Background Technology

[0002] Post-processing equipment is used to produce fiber cloth. It mainly desizing, impregnating coupling agents, and drying and curing the fiber cloth whose surface is coated with sizing agents and sizing agents during the textile process to improve the quality of the fiber cloth.

[0003] Traditional post-processing equipment often adopts a segmented, independent structural design. The three core processes of desizing, impregnation, and drying / curing are arranged independently and equipped with separate power and temperature control systems. As a result, traditional post-processing equipment suffers from long processing cycles, high energy consumption, and high processing costs. Furthermore, the desizing structure of traditional equipment is often an oven-type high-temperature hot air circulation structure. The high-temperature hot air circulation is started intermittently during desizing, and the residual heat after desizing is usually directly discharged or dissipated naturally, failing to effectively utilize the residual heat during the desizing process. This leads to high energy consumption and energy waste. Summary of the Invention

[0004] The purpose of this invention is to provide a low-energy-consumption post-processing machine production equipment to solve the problem of high energy consumption in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A low-energy post-processing machine production equipment includes a winding and unwinding mechanism 1. A desizing mechanism, an impregnation roller and a drying mechanism are sequentially arranged on one side of the winding and unwinding mechanism. A waste heat recovery mechanism is provided on the desizing mechanism, and an impregnation box is provided on one side of the impregnation roller. The waste heat recovery mechanism includes a dust collector and a tank. The dust collector is equipped with a heat exchanger, and the tank is equipped with an exhaust pipe connected to the heat exchanger. The tank is equipped with a sleeve, a pressure switch is located below the sleeve, a baffle is located inside the sleeve, a heat storage unit is located inside the tank, and a temperature control unit is located on one side of the tank. The temperature control unit includes a temperature control box and a preheating hood, and the temperature control box and the preheating hood are connected by pipes; The desizing mechanism is connected to the dust collector via pipeline, and the temperature control box is connected to the tank via pipeline.

[0006] The unwinding mechanism is an automatic unwinding device. It unwinds and conveys the rolled fiber cloth, and a tension adjustment system regulates the tension of the fiber cloth to prevent wrinkles that could affect subsequent processing quality. The fiber cloth is then conveyed to the desizing mechanism, where it undergoes high-temperature desizing. After desizing, the fiber cloth is conveyed to the impregnation rollers, where it is impregnated with a treatment agent. The fiber cloth is then sent to the drying mechanism. A fan carries away the residual heat from the desizing mechanism via airflow. A dust collector removes dust from the airflow to prevent it from affecting subsequent heat exchange efficiency. The dust collector outlet is connected to the heat exchanger pipe, allowing the airflow to be delivered into the heat exchanger. A fan is installed at the inlet of another heat exchange port in the heat exchanger, and a temperature sensor inside the heat exchanger controls the fan power based on the temperature, causing the fan to generate airflow to deliver heat into the heat exchanger. The outlet of the heat exchange port is connected to the air outlet pipe inside the tank, allowing the heat-exchanged airflow to enter the tank. A sleeve is installed inside the tank, making the tank a multi-layered structure. The upper part of the sleeve is fixed to the tank, while the lower part is floating, allowing the airflow to exit from the bottom of the sleeve. When the airflow is small, the airflow passes directly through the inside of the sleeve and exits. When the airflow increases and can drive the air pressure switch, the airflow continuously flows through the outlet on the side of the sleeve to the outside of the sleeve, allowing part of the airflow to pass through the heat storage unit on the outside of the sleeve and store some heat, thus initially cooling the airflow. The cooled airflow is further regulated by the temperature control box of the temperature control unit and conveyed to the preheating hood. The airflow is then output to the fiber cloth at the inlet of the drying mechanism through the preheating hood, thus pre-drying the fiber cloth. Subsequently, the fiber cloth is dried by the drying mechanism. The dried fiber cloth is then wound up by the winding machine of the winding and unwinding mechanism, thus completing the post-processing of the fiber cloth.

[0007] Furthermore, several air outlets are provided on the side of the air outlet pipe; The sleeve has several through holes; Several through holes and several air vents are staggered.

[0008] By setting several baffles on the inner side of the sleeve, the sleeve is divided into several fan-shaped flow channels. Several through holes and several air outlets are staggered, so that the through holes and air outlets are located in different fan-shaped flow channels. At low flow rates, the airflow can only flow downward in the corresponding fan-shaped flow channel. There is a gap between the baffles and the air outlet pipe. The air outlet is set at an angle, so that the airflow at the air outlet flows vertically downward in the fan-shaped flow channel. The airflow is directly output through the channel on the inner side of the sleeve, which initially cools the airflow. When the airflow is large, the fan-shaped flow channel is filled with gas, which increases the flow resistance. The airflow then flows into the fan-shaped flow channel where the through hole is located. When the airflow fills the fan-shaped flow channel where the through hole is located, part of the airflow flows into the flow channel on the outer side of the sleeve through the through hole. The airflow is initially cooled by the heat storage unit on the outer side. The pressure switch is only set in the outer layer of the sleeve. As the gas fills the flow channel on the outer side of the sleeve, the pressure rises, which drives the pressure switch to open, forming a multi-layer heat storage structure controlled by the airflow.

[0009] Furthermore, the thermal storage unit includes a fixed ring, and a heat-conducting pipe is provided inside the fixed ring; The heat pipe is spiral-shaped and filled with phase change heat storage material.

[0010] By setting a hollow fixed ring inside the tank, the fixed ring is made of thermally conductive material. When the airflow passes through the fixed ring, the fixed ring conducts heat to the spiral heat-conducting pipe. The phase change heat storage material inside the heat-conducting pipe stores some of the heat. When the airflow temperature is low, the phase change heat storage material releases heat and transfers it to the airflow, causing the airflow to heat up. The spiral heat-conducting pipe is designed to prevent the phase change heat storage material from expanding and damaging the heat-conducting pipe.

[0011] Furthermore, the pneumatic switch includes a sealing plate, a sliding rod on the sealing plate, and a return spring on the sliding rod; The sliding rod and the tank are slidably connected.

[0012] By setting a sealing plate, the shape of the sealing plate and the air outlet below the sleeve are matched to seal the air outlet. A sliding rod is set on the sealing plate, which is slidably connected to the tank body so that it can slide vertically. A return spring is fitted on the sliding rod to provide preload. When the air pressure increases, the air pressure pushes the sealing plate to slide downward against the elastic force of the return spring, thereby opening the switch.

[0013] Furthermore, the temperature control box is connected to the tank via pipelines. The temperature control box is equipped with a baffle plate, and an air inlet pipe is located on one side of the temperature control box. A solenoid valve is installed on the air inlet pipe, and a baffle plate is located inside the temperature control box.

[0014] The temperature control chamber is connected to the tank body via a pipe at the top, allowing airflow to enter from the top. A guide vane forms an S-shaped flow channel. An intake pipe on the side of the chamber draws in external cold air through a fan. The intake pipe outlet is located on a vertical channel within the S-shaped flow channel formed by the guide vane, ensuring the airflow entering the tank and the airflow entering through the intake pipe are perpendicular, causing them to collide and initially mix. A baffle plate inside the chamber extends the S-shaped flow channel, prolonging the mixing time. A solenoid valve on the intake pipe, controlled by a temperature sensor, controls the intake volume of cold air and thus the temperature range. Multiple temperature control units can be connected in series to improve temperature control accuracy.

[0015] Furthermore, the drying mechanism includes a conveyor roller with heating plates on both sides.

[0016] The fiber cloth to be dried is conveyed by a conveyor roller, and heating plates, which are infrared radiation heating plates, are set on the upper and lower sides of the conveyor roller to dry the fiber cloth in a non-contact manner.

[0017] Furthermore, the preheating hood is equipped with an air outlet; The air outlet faces the conveyor roller.

[0018] By setting a preheating hood above the fiber cloth at the entrance of the drying unit, with the opening of the preheating hood facing the fiber cloth on the conveyor roller, the air outlet of the preheating hood faces the fiber cloth, and the temperature-controlled airflow flows from the air outlet of the preheating hood to the fiber cloth, thereby pre-drying the fiber cloth.

[0019] Furthermore, the desizing mechanism includes a desizing box, a desizing roller inside the desizing box, and a self-cleaning mechanism on the desizing roller; The desizing roller has a cavity inside and two spiral grooves on it. The two spiral grooves are in opposite directions. The desizing box is connected to the dust collector pipe.

[0020] By installing a desizing roller inside the desizing box, and connecting the external air source device to the desizing roller via a rotary joint, the external air source device inputs a high-temperature medium into the cavity inside the desizing roller, maintaining a high temperature on the surface of the desizing roller. When the fiber cloth is conveyed on the desizing roller, two spiral grooves in opposite directions are opened on the outer surface of the roller. Through holes on the spiral grooves that connect to the cavity, the high-temperature airflow is sprayed directly onto the cloth surface from the holes at the bottom of the spiral grooves, softening and evaporating the wetting agent and sizing on the cloth surface, thereby achieving the desizing effect. At the same time, the double spiral grooves generate axial thrust when the roller rotates, pushing the softened sizing and volatiles to both ends of the roller and discharging them, avoiding accumulation in the middle of the roller surface, thus achieving uniform desizing and assisting in self-cleaning. The desizing box is connected to a dust collector pipeline, and the waste heat airflow from the desizing box is sent to the dust collector by a fan.

[0021] Furthermore, the self-cleaning mechanism includes a drive motor and a fixed block, with a vibrating block on the drive motor, and the vibrating block and the fixed block abutting against each other; The desizing roller and the fixed block are rotatably connected, and a pre-tensioning spring is provided between the fixed block and the desizing box.

[0022] The vibrating block is a cam or eccentric wheel, which is driven by a motor to rotate the vibrating block. The vibrating block periodically impacts the fixed block, which is rotatably connected to the desizing roller. A pre-tightening spring is installed between the fixed block and the desizing box. When the vibrating block impacts the fixed block, the vibration is transmitted to the desizing roller through the fixed block, causing the desizing roller to generate axial high-frequency micro-vibration. This shakes off the residual slurry and coking material adhering to the roller surface and spiral groove, thereby preventing the slurry from hardening on the desizing roller and affecting the desizing effect.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a waste heat recovery mechanism, the high-temperature flue gas generated by the desizing mechanism is used for preheating and drying of the drying mechanism after dust removal and heat exchange, which realizes the efficient utilization of heat energy, greatly reduces the external energy required for drying, and thus reduces energy consumption.

[0024] 2. By installing sleeves, baffles, and heat storage units inside the tank, heat is absorbed or released during the melting and solidification process of phase change heat storage materials. Combined with a pressure switch, the flow rate is adaptively controlled to allow small air volumes to be directly output and large air volumes to enter the heat storage unit for air exchange, thereby suppressing temperature fluctuations and improving the quality of subsequent drying.

[0025] 3. The cold air volume is precisely controlled by a solenoid valve based on a temperature sensor to achieve high-precision temperature regulation. Multiple temperature control units are connected in series to further improve the temperature control accuracy and meet the different drying temperature requirements of different fiber fabrics.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example: Figures 1-6 As shown, the present invention provides a technical solution: a low-energy post-processing machine production equipment. The production equipment includes a winding and unwinding mechanism 1. On one side of the winding and unwinding mechanism 1, a desizing mechanism 3, an impregnation roller 4, and a drying mechanism 5 are arranged in sequence. The desizing mechanism 3 is provided with a waste heat recovery mechanism 6. The impregnation roller 4 is provided with an impregnation box 2 on one side. The waste heat recovery mechanism 6 includes a dust collector 61 and a tank 63. The dust collector 61 is equipped with a heat exchanger 62. The tank 63 is equipped with an exhaust pipe 64, which is connected to the heat exchanger 62. The tank 63 is equipped with a sleeve 65, and a pressure switch 67 is located below the sleeve 65. A baffle 66 is located inside the sleeve 65. The tank 63 is equipped with a heat storage unit 68, and a temperature control unit 69 is located on one side of the tank 63. Temperature control unit 69 includes temperature control box 691 and preheating cover 696, and temperature control box 691 and preheating cover 696 are connected by pipes; The desizing mechanism 3 and the dust collector 61 are connected by pipes, and the temperature control box 691 and the tank 63 are connected by pipes.

[0030] The unwinding mechanism 1 is an automatic unwinding device. It unwinds and conveys the rolled fiber cloth, and adjusts the tension of the fiber cloth using a tension regulating system to prevent wrinkles from affecting the quality of subsequent processing. The fiber cloth is then conveyed to the desizing mechanism 3, where it undergoes high-temperature desizing. After desizing, the fiber cloth is conveyed to the impregnation roller 4, where it is impregnated with a treatment agent in the impregnation tank 2. The fiber cloth is then sent to the drying mechanism 5. A fan carries away the residual heat from the desizing mechanism 3 via airflow. Dust is removed from the airflow by a dust collector 61 to prevent dust from affecting the efficiency of subsequent heat exchange. The outlet of the dust collector 61 is connected to the heat exchanger 62 via a pipe, allowing the airflow to be delivered into the heat exchanger 62. A fan is installed at the inlet of another heat exchange port in the heat exchanger 62, and a temperature sensor inside the heat exchanger 62 controls the fan power based on the temperature, causing the fan to generate airflow that is delivered into the heat exchanger 62 for heat exchange. The airflow is then delivered to the tank 63 via the outlet of the other heat exchange port in the heat exchanger 62. The air outlet pipe 64 inside the tank is connected to the heat exchanged airflow into the tank 63. A sleeve 65 is installed inside the tank 63, making the tank 63 a multi-layer structure. The upper part of the sleeve 65 is fixed to the tank 63, while the lower part is floating, allowing the airflow to be output from the bottom of the sleeve 65. When the airflow is small, the airflow passes directly through the inside of the sleeve 65 and is output. When the airflow increases and can drive the air pressure switch 67, the airflow continues to flow through the outlet on the side of the sleeve 65 to the outside of the sleeve 65, so that part of the airflow passes through the heat storage unit 68 on the outside of the sleeve 65 and stores some heat, thereby initially cooling the airflow. The cooled airflow is further regulated in temperature by the temperature control box 691 of the temperature control unit 69 and conveyed to the preheating hood 696. The airflow is output to the fiber cloth at the inlet of the drying mechanism 5 through the preheating hood 696, thereby pre-drying the fiber cloth. Then, the fiber cloth is dried by the drying mechanism 5. The dried fiber cloth is wound up by the winding machine of the winding and unwinding mechanism 1, thereby completing the post-processing of the fiber cloth.

[0031] like Figure 3 As shown, the side of the vent pipe 64 is provided with several vent holes 641; The sleeve 65 is provided with several through holes 651; Several through holes 651 and several vent holes 641 are staggered.

[0032] By setting several baffles 66 inside the sleeve 65, the sleeve 65 is divided into several fan-shaped flow channels. Several through holes 651 and several air outlets 641 are staggered, so that the through holes 651 and air outlets 641 are located in different fan-shaped flow channels. At low flow rates, the airflow can only flow downwards within the corresponding fan-shaped flow channel. A gap is provided between the baffles 66 and the air outlet 64. The air outlets 641 are inclined, allowing the airflow at the outlets 641 to flow vertically downwards within the fan-shaped flow channels. This allows the airflow to be directly output through the channels inside the sleeve 65, thereby improving the airflow... Initial cooling increases the gas flow rate, filling the fan-shaped channel with gas and increasing the flow resistance. This causes the gas to flow into the fan-shaped channel where the through hole 651 is located. When the gas fills the fan-shaped channel where the through hole 651 is located, some of the gas flows through the through hole 651 into the channel outside the sleeve 65. The gas passes through the outer heat storage unit 68 for initial cooling. The pressure switch 67 is only set in the outer layer of the sleeve 65. As the gas fills the channel outside the sleeve 65, the gas pressure increases, which in turn drives the pressure switch 67 to open, forming a multi-layer heat storage structure controlled by the gas flow rate.

[0033] like Figure 4 As shown, the heat storage unit 68 includes a fixing ring 681, and a heat-conducting pipe 682 is provided inside the fixing ring 681; The heat pipe 682 is spiral-shaped and is filled with phase change heat storage material.

[0034] By setting a hollow fixing ring 681 inside the tank 63, the fixing ring 681 is made of heat-conducting material. When the airflow flows through the fixing ring 681, the fixing ring 681 conducts heat to the spiral heat-conducting pipe 682. Part of the heat is stored by the phase change heat storage material inside the heat-conducting pipe 682. When the airflow temperature is low, the phase change heat storage material releases heat and transfers it to the airflow, causing the airflow to heat up. By setting the spiral heat-conducting pipe 682, the expansion of the phase change heat storage material is prevented from damaging the heat-conducting pipe 682.

[0035] like Figure 5 As shown, the pneumatic switch 67 includes a sealing plate 671, a sliding rod 672 on the sealing plate 671, and a return spring 673 on the sliding rod 672. The sliding rod 672 and the tank body 63 are slidably connected.

[0036] By setting a sealing plate 671, the shape of the sealing plate 671 and the air outlet below the sleeve 65 are matched to seal the air outlet. By setting a sliding rod 672 on the sealing plate 671, the sliding rod 672 is slidably connected to the tank body 63, so that it can slide vertically. By setting a return spring 673 on the sliding rod 672 to provide pre-tightening force, when the air pressure increases, the air pressure pushes the sealing plate 671 to slide downward against the elastic force of the return spring 673, thereby opening the switch.

[0037] like Figure 6 As shown, the temperature control box 691 and the tank 63 are connected by pipes. The temperature control box 691 is equipped with a guide plate 692. The temperature control box 691 is equipped with an air inlet pipe 693 on one side. The air inlet pipe 693 is equipped with a solenoid valve 694. The temperature control box 691 is equipped with a baffle plate 695.

[0038] The temperature control chamber 691 is connected to the tank 63 by a pipe, allowing airflow to enter from the top of the chamber. A guide plate 692 forms an S-shaped flow channel. An inlet pipe 693 is installed on the side of the chamber, and a fan on the inlet pipe 693 drives external cold airflow into the chamber. The outlet of the inlet pipe 693 is located on a vertical channel of the S-shaped flow channel formed by the guide plate 692, ensuring that the airflow entering the tank 63 and the airflow input through the inlet pipe 693 are perpendicular, causing the two airflows to collide and initially mix. A baffle plate 695 is installed inside the temperature control chamber 691, forming an extended S-shaped flow channel to prolong the mixing time. A solenoid valve 694 is installed on the inlet pipe 693, and its opening and closing are controlled by a temperature sensor to control the amount of cold air entering the chamber, thereby controlling the temperature range. Multiple temperature control units 69 can be connected in series to improve temperature control accuracy.

[0039] like Figure 2 As shown, the drying mechanism 5 includes a conveying roller 51, and heating plates 52 are provided on both sides of the conveying roller 51.

[0040] The fiber cloth to be dried is conveyed by the conveyor roller 51, and the fiber cloth is dried in a non-contact manner by setting heating plates 52 on the upper and lower sides of the conveyor roller 51. The heating plates 52 are infrared radiation heating plates 52.

[0041] like Figure 6 As shown, the preheating hood 696 is provided with an air outlet 6961; The air outlet 6961 faces the conveyor roller 51.

[0042] By setting a preheating hood 696 above the fiber cloth at the inlet of the drying mechanism 5, with the opening of the preheating hood 696 facing the fiber cloth on the conveying roller 51, the air outlet 6961 of the preheating hood 696 faces the fiber cloth, so that the temperature-controlled airflow flows from the air outlet 6961 of the preheating hood 696 to the fiber cloth, thereby pre-drying the fiber cloth.

[0043] like Figure 2 and Figure 7 As shown, the desizing mechanism 3 includes a desizing box 31, a desizing roller 32 is provided inside the desizing box 31, and a self-cleaning mechanism 33 is provided on the desizing roller 32; The desizing roller 32 has a cavity 321 inside and two spiral grooves 322 on it. The two spiral grooves 322 are in opposite directions. The desizing box 31 is connected to the dust collector 61 by a pipe.

[0044] By installing a desizing roller 32 inside the desizing box 31, and connecting the external air source device to the desizing roller 32 via a rotary joint, the external air source device inputs a high-temperature medium into the cavity 321 inside the desizing roller 32, maintaining a high temperature on the surface of the desizing roller 32. When the fiber cloth is conveyed on the desizing roller 32, two spiral grooves 322 with opposite directions are opened on the outer surface of the roller. Through the holes on the spiral grooves 322 and the cavity 321, the high-temperature airflow is sprayed directly onto the cloth surface from the holes at the bottom of the spiral grooves 322, softening and evaporating the wetting agent and sizing on the cloth surface, thereby achieving the desizing effect. At the same time, the double spiral grooves 322 generate axial thrust when the roller rotates, pushing the softened sizing and volatiles to both ends of the roller and avoiding accumulation in the middle of the roller surface, thereby achieving uniform desizing and assisting self-cleaning. The desizing box 31 is connected to the dust collector 61 by a pipe, and the waste heat airflow from the desizing box 31 is sent to the dust collector 61 by a fan.

[0045] like Figure 8 As shown, the self-cleaning mechanism 33 includes a drive motor 331 and a fixing block 333. The drive motor 331 is provided with a vibration block 332, and the vibration block 332 and the fixing block 333 abut against each other. The desizing roller 32 and the fixed block 333 are rotatably connected, and a pre-tightening spring 334 is provided between the fixed block 333 and the desizing box 31.

[0046] The vibrating block 332 is a cam or eccentric wheel, which is driven by the drive motor 331 to rotate the vibrating block 332. The vibrating block 332 periodically impacts the fixed block 333. The fixed block 333 is rotatably connected to the desizing roller 32. A pre-tightening spring 334 is provided between the fixed block 333 and the desizing box 31. When the vibrating block 332 impacts the fixed block 333, the vibration is transmitted to the desizing roller 32 through the fixed block 333. This causes the desizing roller 32 to generate axial high-frequency micro-vibration, which shakes off the residual slurry and coking material adhering to the roller surface and spiral groove 322, thereby preventing the slurry from hardening on the desizing roller 32 and affecting the desizing effect.

[0047] Working principle of the invention: The roll of fiberglass cloth is unwound by the automatic unwinding machine of the winding and unwinding mechanism 1. After being kept under constant tension by the tension adjustment system, it is conveyed to the desizing roller 32. High-temperature airflow is input into the desizing roller 32 through an external air source. High-temperature gas is sprayed onto the cloth surface through the holes at the bottom of the spiral groove 322, which quickly softens and evaporates the impregnating agent and sizing, thus desizing. At the same time, the drive motor 331 drives the vibrating block 332 to periodically strike the fixed block 333, causing the desizing roller 32 to generate high-frequency micro-vibration, removing the sizing adhering to the desizing roller 32. The desizing fiberglass cloth enters the impregnation tank 2 and is impregnated with coupling agent by the impregnation roller 4. Meanwhile, the residual heat from desizing is drawn into the dust collector 61 by the fan to remove dust, and then enters the heat exchanger 62 to exchange heat with fresh air. The hot air after heat exchange enters the tank 63 through the air outlet pipe 64. When the air volume is small, the hot air is directly output downward from the inside of the sleeve 65. When the air volume increases, the hot air is directly output downward. At this time, the airflow overflows through the partition 66 and enters the adjacent fan-shaped flow channel. It flows into the outside of the sleeve 65 through the through hole 651 and exchanges heat with the phase change material in the spiral heat conduction pipe 682, thereby suppressing temperature fluctuations. After the outer air pressure increases, it pushes the sealing plate 671 of the air pressure switch 67 to open downward. Then the airflow enters the temperature control unit 69 and collides and mixes with the cold air added by the air inlet pipe 693 in the S-shaped flow channel. The mixing path is extended by the baffle plate 695 and then sent into the preheating hood 696. Hot air is blown onto the fiber cloth on the conveying roller 51 through the air outlet 6961 of the preheating hood 696 to achieve pre-drying. Then the fiber cloth enters the drying mechanism 5 and is dried and cured non-contactly by the infrared radiation heating plates 52 on the upper and lower sides. The finished cloth after drying is wound up by the winding machine of the winding and unwinding mechanism 1, thereby efficiently completing the entire process of desizing, impregnation and drying.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
