Description

Technical Field

[0001] This utility model mainly relates to the field of fabric pre-shrinking and shaping machines. Background Technology

[0002] In the fabric processing industry, fabric pre-shrinking and setting is an important process. Its purpose is to pre-shrink the fabric to a certain extent to stabilize its dimensions and improve its quality. Existing fabric pre-shrinking and setting machines typically suffer from problems such as high energy consumption, water waste, large footprint, and pollution emissions.

[0003] Traditional pre-shrink washing methods involve soaking or spraying large amounts of water, resulting in high water consumption, significant waste, and pollution due to the lack of water recycling. Furthermore, excessive water usage can cause fabric fading, and the increased weight of the fabric due to water absorption makes it prone to stretching and deformation during dehydration. Additionally, these machines are often bulky and require substantial space.

[0004] With increasing environmental protection requirements and rising energy costs, developing an energy-saving, water-saving, and space-saving fabric pre-shrinking and shaping machine is of great practical significance. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a low-energy fabric pre-shrinking and shaping machine that is energy-saving, water-saving, reduces emissions, and has a good pre-shrinking effect, in response to the shortcomings of the existing technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A low-energy fabric pre-shrinking and shaping machine includes a conveyor belt and a spraying zone, a drying zone, and a cooling zone arranged sequentially along the conveying direction of the conveyor belt. The spraying zone is equipped with a spraying device and a steam spraying device along the conveying direction. The spraying device and the steam spraying device are located above the conveyor belt of the spraying zone and are used to spray water mist and steam onto the fabric on the conveyor belt of the spraying zone, respectively. A water vapor condensation tray is provided below the conveyor belt of the spraying zone to collect water that is not absorbed by the fabric during the spraying process and condensate generated during the steam spraying process. A drain outlet is provided at the lower position of the water vapor condensation tray. The drain outlet is connected to a water tank through a recovery pipe to recover the water collected in the water vapor condensation tray to the water tank. The water in the water tank is filtered and then supplied to the spraying device.

[0008] Furthermore, the side wall of the water vapor condensation plate is provided with an air intake, which is connected to a suction fan. The suction fan creates a negative pressure above the water vapor condensation plate, drawing the water mist and steam that have penetrated the fabric into the water vapor condensation plate.

[0009] Furthermore, the air outlet of the suction fan is connected to the water tank through a pipe, sending air into the water tank and using the waste heat of the air to heat the water in the tank.

[0010] Furthermore, a spray pipe is provided at the top of the water tank, and an air inlet and an air outlet are provided on the side wall of the water tank. The air inlet and the air outlet are located below the spray pipe. The air from the suction fan enters the water tank through the air inlet and is discharged from the air outlet. The water in the water tank is pumped to the spray pipe and sprayed out, making full contact with the air sent into the water tank to absorb the residual heat of the air.

[0011] Furthermore, the water vapor condensation pan is equipped with a condenser tube to accelerate the condensation of steam. Cold water is introduced into the condenser tube, the water inlet of the condenser tube is supplied by an external water source, and the water outlet of the condenser tube leads to the water tank.

[0012] Furthermore, the water tank is equipped with a float valve to control the water level in the tank. When the water level reaches the set value, the water from the condenser tube is stopped from being sent into the water tank.

[0013] Furthermore, the condenser tubes are arranged in an S-shape within the water vapor condensation pan.

[0014] Furthermore, a suction box is provided inside the water vapor condensation plate, and the side wall of the suction box is densely covered with suction holes. One end of the suction box is connected to the suction port.

[0015] Furthermore, the spraying and drying zones are located inside the first housing, and the cooling zone is located inside the second housing. A cooling box is provided below the conveyor belt in the cooling zone. The top of the cooling box is densely covered with exhaust holes, and the side wall of the cooling box is provided with an exhaust port. The exhaust port is connected to an exhaust fan through an exhaust pipe. The exhaust fan is located below the conveyor belt in the drying zone, and the exhaust fan blows air upward toward the conveyor belt.

[0016] Furthermore, the spraying and drying zones are located inside the first housing, and the conveyor belt inside the first housing is a multi-layer conveyor belt, on which the fabric is conveyed in an S-shape from top to bottom.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. This utility model uses a combination of spraying and steam to humidify the fabric, which uses less water and effectively prevents the fabric from fading and stretching. It also reduces the heat energy required for subsequent drying, avoids the problem of fabric hardening caused by high-temperature drying, and has a better pre-shrinking effect.

[0019] 2. A water vapor condensation tray is installed below the conveyor belt in the spraying zone to collect water that is not absorbed by the fabric during the spraying process and condensate generated during the steam spraying process. The collected water is recycled to the water tank through a recycling pipe. The water in the water tank is filtered and then supplied to the spraying device, thereby realizing the recycling of water, saving water resources and reducing emissions.

[0020] 3. By drawing air through the suction fan, a negative pressure is created above the water vapor condensation plate, which can draw the water mist and steam that have penetrated the fabric into the water vapor condensation plate, preventing the water mist and steam from flowing around inside the casing and causing water to flow on the inner wall of the casing;

[0021] 4. The heat generated during the steam condensation process is drawn into the water tank by the suction fan. The residual heat of the air can heat the water in the tank, and the heated water is then supplied to the spraying device for better spraying effect on the fabric.

[0022] 5. The water vapor condensation pan is equipped with condenser tubes, which can accelerate the condensation of steam. The water outlet of the condenser tubes leads to the water tank, which can realize the secondary recycling of water.

[0023] 6. The cooling zone cools the fabric by exhausting air. The exhaust air removes the residual heat of the fabric and blows it toward the conveyor belt in the drying zone. This not only realizes the secondary utilization of heat energy, but also uses the wind power to make the fabric on the conveyor belt float slightly and maintain a small distance from the conveyor belt, reducing friction and improving the pre-shrinking effect of the fabric. At the same time, the air circulation in the machine can also reduce water condensation on the inner wall of the machine.

[0024] 7. Multi-layer conveyor belts can reduce the machine's lateral dimensions and floor space. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the protection scope of the present invention is not limited to the following embodiments. Any improvements and modifications made to the present invention without departing from the principle of the present invention shall be considered within the protection scope of the present invention.

[0031] like Figure 1 As shown, the low-energy fabric pre-shrinking and shaping machine of this utility model includes a fabric feeding shaft 1, a fabric guide shaft 2, an electrical control box 3, a first housing 4, a second housing 5, a conveyor belt 6, and a spraying zone, a drying zone, and a cooling zone arranged sequentially along the conveying direction of the conveyor belt 6. The spraying zone and the drying zone are located inside the first housing 4, and a partition 7 is provided between the spraying zone and the drying zone. The cooling zone is located inside the second housing 5. The fabric enters the conveyor belt 6 along the fabric feeding shaft 1 and the fabric guide shaft 2, and then passes through the spraying zone, the drying zone, and the cooling zone sequentially along the conveyor belt 6, finally exiting from the fabric outlet 8.

[0032] The spraying zone is equipped with a spraying device 9 and a steam spraying device 10 sequentially along the conveying direction. The spraying device 9 and steam spraying device 10 are positioned above the conveyor belt 6 in the spraying zone, respectively used to spray water mist and steam onto the fabric on the conveyor belt 6. The spraying device 9 uses an atomizing nozzle, which can atomize water into tiny particles, spraying them evenly onto the fabric surface. It also allows for precise control of the water spray volume, saving water and energy. The steam spraying device 10 uses a steam nozzle, directly injecting high-temperature steam onto the fabric. This avoids steam heat diffusion, improves steam utilization efficiency, and allows the steam to penetrate the fabric directly at high temperature and pressure, resulting in a direct pre-shrinking effect and strong penetration.

[0033] A water vapor condensation pan 11 is installed below the conveyor belt 6 in the spraying zone, such as... Figure 2As shown, the water vapor condensation tray 11 is a square tray used to collect water that is not absorbed by the fabric during the spraying process and condensate generated during the steam spraying process. An air intake 12 is provided on the side wall of the water vapor condensation tray 11, which is connected to a suction fan 13. The suction creates a negative pressure above the water vapor condensation tray 11, drawing the water mist and steam that have penetrated the fabric into the water vapor condensation tray 11, preventing steam from flowing freely within the first housing 4 and causing water to drip onto the inner wall of the first housing 4. Preferably, an air intake box 14 is provided inside the water vapor condensation tray 11. One end of the air intake box 14 is connected to the air intake 12, and the side wall of the air intake box 14 is densely covered with air intake holes 15. The air intake holes 15 on the side wall of the air intake box 14 prevent condensate from dripping into the air intake box 14. The steam condensation pan 11 is equipped with condenser tubes 16 to accelerate steam condensation. The condenser tubes 16 are arranged in an S-shape within the steam condensation pan 11. Cold water flows through the condenser tubes 16, with the inlet 17 supplied by an external water source. The outlet 18 of the condenser tubes 16 leads to a water tank 19. The water tank 19 is equipped with a float valve 20 to control the water level. When the water level reaches a set value, the flow of water from the condenser tubes 16 into the water tank 19 stops to prevent overflow. A drain outlet 21 is located at the lower part of the steam condensation pan 11, situated on its side wall and close to the bottom. The drain outlet 21 is connected to the water tank 19 via a recovery pipe 22 to recover the water collected in the steam condensation pan 11 back to the water tank 19. The water tank 19 is equipped with a filter screen 23, which divides the water tank 19 into a water storage area 24 and a clean water area 25. Water from the condenser pipe 16 and the water vapor condensation pan 11 is discharged into the water storage area 24, and the water in the water storage area 24 is filtered by the filter screen 23 before entering the clean water area 25. Figure 1 As shown, the water purification zone 25 is connected to the spray device 9 and is used to supply filtered clean water to the spray device 9, thereby realizing water recycling, saving water resources, and reducing emissions.

[0034] like Figure 2 As shown, the air outlet of the suction fan 13 is connected to the water tank 19 via a pipe, sending air into the water storage area 24 of the water tank 19. Since the steam condensation process releases heat, the air drawn in by the suction fan 13 carries residual heat. This residual heat can be used to heat the water in the water tank 19, and the heated water is then supplied to the spray device 9, resulting in better spraying of the fabric. Preferably, a spray pipe 26 is provided at the top of the water storage area 24 in the water tank 19, and an air inlet 27 and an air outlet 28 are provided on the side wall of the water tank 19. The air inlet 27 and the air outlet 28 are located below the spray pipe 26. The air from the suction fan 13 enters the water tank 19 through the air inlet 27 and exits through the air outlet 28. The water in the clean water area 25 of the water tank 19 is pumped by the water pump 29 to the spray pipe 26 and sprayed out, making full contact with the air sent into the water tank 19 to absorb the residual heat of the air. This circulating spraying method can significantly increase the contact between water and air, improving the heat absorption effect.

[0035] like Figure 1 , Figure 3 As shown, a vibrating shaft 30 is installed at the bottom of the conveyor belt 6 in the drying zone. The vibrating shaft 30 is driven to rotate by a motor. The outer periphery of the vibrating shaft 30 has protrusions. The rotation of the vibrating shaft 30 causes the protrusions to continuously strike the conveyor belt 6, generating a vibration effect. The vibrating shaft 30 can apply vibrations of a certain frequency and amplitude to the fabric, reducing the impact of friction between the fabric and the conveyor belt 6 on the shrinkage force, allowing the fabric to shrink more evenly, further improving the pre-shrinking effect of the fabric, and ensuring the flatness and quality stability of the fabric. In this embodiment, the outer periphery of the vibrating shaft 30 is triangular, and the three corners of the triangle form the protrusions. When the vibrating shaft 30 rotates, the three corners alternately collide with the bottom of the conveyor belt 6, generating a striking vibration effect.

[0036] like Figure 1 , Figure 4 As shown, a cooling box 31 is located below the cooling zone conveyor belt 6. The cooling box 31 is a square box with numerous exhaust holes 32 on its top and exhaust vents 33 on its side walls. The exhaust vents 33 are connected to an exhaust fan 35 via an exhaust pipe 34. The exhaust fan 35 is located below the drying zone conveyor belt 6, with its outlet blowing air upwards toward the drying zone conveyor belt 6. The fabric is cooled by exhaust, and the residual heat of the fabric is drawn away and blown toward the drying zone conveyor belt 6. This not only achieves secondary utilization of heat energy but also uses the airflow to slightly lift the fabric on the conveyor belt 6, maintaining a small gap with the belt, reducing friction and improving the pre-shrinking effect of the fabric. Simultaneously, the airflow within the first housing 4 reduces water condensation on the inner wall of the first housing 4.

[0037] like Figure 1 As shown, the conveyor belt 6 inside the first housing 4 is a multi-layer conveyor belt 6. The fabric is conveyed in an S-shape from top to bottom on the multi-layer conveyor belt 6. The multi-layer conveyor belt 6 can reduce the lateral size of the machine and reduce the machine's floor space. Multiple heating plates 36 are spaced apart below the conveyor belt 6 in the drying zone to dry the fabric on the conveyor belt 6. A heat insulation plate 37 is provided below the bottom layer of the conveyor belt 6, and the exhaust fan 35 and water tank 19 are both located below the heat insulation plate 37.
