Fabric double-side drying device

Abstract

This utility model relates to the field of fabric drying, specifically disclosing a double-sided fabric drying device, including a base and a frame. The drying device also includes a clamping assembly. Two pieces of fabric to be dried are overlapped, with the width of the fabric being greater than the distance between the clamping rods on both sides. The fabric passes through the space between two flat rollers on one side, with the side edge of the fabric being clamped into the clamping groove and moving along the clamping groove towards the flat roller on the other side. When the fabric on the upper and lower sides passes through the box, the two layers of fabric are separated and pass through the upper and lower sides of the box respectively. Finally, the two layers of fabric pass through the space between two flat rollers on the other side. During the fabric conveying process, hot drying air is input from the air inlet pipe and then discharged from the second air outlet and the first air outlet, thereby drying the fabric on the upper and lower sides. Most of the hot air is trapped between the upper and lower fabrics, thereby increasing the utilization rate of the hot air heat and reducing the amount of hot air directly discharged into the working environment.

Description

Technical Field

[0001] This utility model relates to the field of fabric drying, specifically a fabric double-sided drying device. Background Technology

[0002] In the textile printing and dyeing industry, fabrics typically contain a large amount of moisture after dyeing or printing processes, requiring fabric drying equipment to dry them. Traditional fabric drying equipment (such as hot air tenter frames, drum dryers, and non-contact hot air drying rooms) mainly works by using heating elements (such as steam radiators, electric heating tubes, and gas-fired hot air furnaces) to generate hot air. The hot air is then forced onto or circulated through the surface of a single layer of fabric by a fan. The convection and conduction of the hot air evaporate the moisture in the fabric. However, because the hot air is directly convected with the fabric surface, it is directly dissipated into the working environment. This results in the heat generated by the fabric drying equipment not being fully utilized. The portion of the hot air dissipated directly into the working environment also causes the temperature of the working environment to rise, reducing the comfort of the working environment. Utility Model Content

[0003] The purpose of this invention is to provide a fabric double-sided drying device to overcome the above-mentioned defects in the prior art.

[0004] A fabric double-sided drying device according to the present invention includes a base and a frame, and the drying device further includes: The clamping assembly includes two clamping rods that are symmetrically fixed to the frame. Each clamping rod has a hollow interior forming a slot and openings at both ends. On the side of the two clamping rods that are close to each other, there is a circular slot that communicates with the hollow slot. On the sidewall of the circular slot, there are two symmetrically arranged clamping slots that are parallel to the length direction of the clamping rod. The end of the clamping slot away from the circular slot is open, and the end of the clamping slot close to the circular slot is connected to the circular slot. The drying assembly comprises two units located between two clamping rods. Each assembly includes a vertically penetrating groove within its housing, perpendicular to the clamping rods. A main pipe, perpendicular to the clamping rods, is fixed within the housing and passes through the groove. Multiple first air outlets are located on the periphery of the main pipe. T-junctions are fixed at both ends of the main pipe. A secondary pipe, connected to the main pipe, is fixed between two of the t-junctions. Multiple second air outlets are located on the periphery of the secondary pipe. An air inlet pipe, coinciding with and connected to the main pipe's axis, is also fixed to the t-junction. The air inlet pipe passes through a circular groove on the clamping rod and is fixed to it. Dry, hot air is output into the groove through the air inlet pipe.

[0005] Furthermore, the thickness of the box body gradually decreases from the middle to both ends in a rhombus shape along the vertical direction, and the middle part of the upper and lower surface of the box body is an arc segment, with the fabric passing through the upper and lower sides of the drying component in two layers.

[0006] Furthermore, the inside of the channel sidewall is hollow, and the upper side of the box is provided with several water collection grooves perpendicular to the fabric conveying direction. The water collection grooves are connected to the cavity inside the channel sidewall. The channel sidewall is provided with through holes that are connected to the cavity inside the channel sidewall, and the through holes are fitted with sealing plugs.

[0007] Furthermore, a number of squeegee strips perpendicular to the fabric movement direction are fixed on the lower side of the housing.

[0008] Furthermore, a gap is formed between the outer periphery of the intake pipe and the sidewall of the circular groove.

[0009] Furthermore, the frame is fixed to the upper surface of the base, and two symmetrically arranged connecting frames are fixed on the frame. The two connecting frames are respectively arranged at both ends of the clamping assembly. Two symmetrically arranged flat rollers are rotatably connected to the connecting frames, and a gap is formed between the upper and lower flat rollers that is flush with the clamping groove.

[0010] The beneficial effects of this utility model are as follows: Two pieces of fabric to be dried are overlapped, with the width of the fabric being greater than the distance between the clamping rods on both sides. The fabric passes between two flat rollers on one side, and the side edge of the fabric is inserted into the clamping groove. It then moves along the clamping groove to the flat roller on the other side. When the fabric on the upper and lower sides passes through the box, the two layers of fabric are separated and pass through the upper and lower sides of the box respectively. Finally, the two layers of fabric pass between two flat rollers on the other side. During the fabric conveying process, hot dry air is introduced from the air inlet pipe and then discharged from the second air outlet and the first air outlet, thereby drying the fabric on the upper and lower sides. Most of the hot air is sealed between the upper and lower fabrics, thereby increasing the utilization rate of the hot air heat and reducing the amount of hot air directly discharged into the working environment.

Therefore, they should not be construed as limitations on this utility model.

[0014] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of this double-sided fabric drying device are described in detail below: One embodiment of this utility model: Reference Figures 1-7 This utility model provides a fabric double-sided drying device, including a base 10 and a frame 11. The drying device also includes: Two clamping assemblies are provided and symmetrically fixed on the frame 11. The clamping assemblies include clamping rods 30. The clamping rods 30 are hollow inside to form a slot 33 and are open at both ends. On the side of the two clamping rods 30 that are close to each other, there is a circular slot 32 that communicates with the slot 33. On the side wall of the circular slot 32, there are two symmetrically arranged clamping slots 31 that are parallel to the length direction of the clamping rods 30. The end of the clamping slot 31 that is away from the circular slot 32 is open, and the end of the clamping slot 31 that is close to the circular slot 32 is connected to the circular slot 32. The drying assembly has two units located between two clamping rods 30. The drying assembly includes a box 40 with a vertical through groove 42 that is perpendicular to the clamping rods 30. A main pipe 46 is fixed inside the box 40, passing through the through groove 42 in a direction perpendicular to the clamping rods 30. Multiple first air outlets 461 are opened on the periphery of the main pipe 46. T-pipes 45 are fixed at both ends of the main pipe 46. A secondary pipe 43 connected to the main pipe 46 is fixed between the two T-pipes 45. Multiple second air outlets 431 are opened on the periphery of the secondary pipe 43. An air inlet pipe 44 is also fixed on the T-pipe 45, which is aligned with the axis of the main pipe 46 and connected to the main pipe 46. The air inlet pipe 44 passes through the circular groove 32 on the clamping rod 30 and is fixed to the clamping rod 30. Dry hot air is output into the through groove 42 through the air inlet pipe 44. An unwinding device is set on one side of the frame 11, which has two unwinding rollers. The two fabrics are unwound and unrolled from the two unwinding rollers respectively. A winding device is set on the other side of the frame 11, which has two winding rollers. The two fabrics after drying are wound up by the two winding rollers respectively. To increase the connection stability between the fabric edge and the clamping groove 31, the fabric edge can be hemmed to increase its thickness, so that the thickness of the two fabric edges is greater than the width of the clamping groove 31, while the total thickness of the remaining parts of the two fabrics is less than the width of the clamping groove 31. This ensures that when the fabric edge passes through the clamping groove 31, the clamping groove 31 can prevent the fabric edge from detaching from the clamping rod 30.

[0015] The thickness of the box 40 gradually decreases from the middle to both ends in a rhombus shape along the vertical direction. The middle part of the upper and lower surfaces of the box 40 is an arc segment. The fabric passes through the upper and lower sides of the drying component in two layers. The rhombus shape of the box 40 can ensure that the fabric is laid flat on the upper and lower sides of the box 40 and remains taut.

[0016] The inside of the side wall of the channel 42 is hollow. Several water collection troughs 41 perpendicular to the fabric conveying direction are opened on the upper side of the box 40. The water collection troughs 41 are connected to the cavity inside the side wall of the channel 42. The side wall of the channel 42 is provided with through holes that are connected to the cavity inside the side wall of the channel 42. A sealing plug 47 is fitted into the through hole. The setting of the water collection troughs 41 allows some of the moisture in the fabric to be scraped into the cavity inside the side wall of the channel 42 when the upper side fabric passes through, further reducing the moisture content of the fabric and thus accelerating the drying speed of the fabric.

[0017] The lower side of the box 40 is fixed with several squeegee strips 48 perpendicular to the direction of fabric movement. The squeegee strips 48 can cause some of the water to be scraped off the fabric as it passes over, thereby speeding up the drying of the fabric on the lower side.

[0018] A gap is formed between the outer periphery of the intake pipe 44 and the side wall of the circular groove 32.

[0019] The frame 11 is fixed to the upper surface of the base 10. Two symmetrically arranged connecting frames 20 are fixed on the frame 11. The two connecting frames 20 are respectively set at both ends of the clamping assembly. Two symmetrically arranged flattening rollers 21 are rotatably connected to the connecting frames 20. The two flattening rollers 21 form a gap that is flush with the clamping groove 31. The symmetrically arranged flattening rollers 21 on both sides of the frame 11 can ensure that the ends of the fabric on the upper and lower sides abut against each other when the fabric passes through the drying assembly, thereby further reducing the heat loss of the hot air blown out by the drying assembly and improving the heat utilization rate of the hot air. At the same time, the flattening rollers 21 on the upper and lower sides can clamp the fabric to improve the flatness of the fabric during the drying process.

[0020] In the process of using this utility model, the unwinding device unwinds two fabrics to be dried. After the two fabrics overlap, they pass between the flattening rollers 21 on the upper and lower sides. The side edges of the fabrics pass through the clamping grooves 31 on both sides. When the side edges of the fabrics pass through the air inlet pipe 44, they separate up and down and move along the gap between the air inlet pipe 44 and the circular groove 32 to the clamping groove 31 on the other side. Then the edges of the fabrics on the upper and lower sides are stacked again and move along the clamping groove 31 until they pass out between the two flattening rollers 21 on the other side. The upper and lower layers of fabric separate as they pass through the box 40 and pass over the upper and lower sides of the box 40 respectively. Because the sides of the fabric are confined within the clamping groove 31, the fabric can be laid flat on the upper and lower surfaces of the box 40 as it passes through (e.g., ...). Figure 7 , Figure 8 As shown in the diagram, the black arrows represent the direction of hot air flow, and the upper side of the drying components is covered with fabric.

[0021] At this time, the air inlet pipe 44 injects dry hot air into the main pipe 46 and the secondary pipe 43. The hot air is blown directly onto the flat fabric through the first air outlet 461. At the same time, when the fabric passes through the water collection tank 41 and the squeegee 48, some of the moisture is scraped off the fabric, reducing the moisture content in the fabric. Meanwhile, when the hot air in the channel 42 blows directly onto the fabric, most of the hot air in the channel 42 can pass through the pores on the fabric, thereby taking away a large amount of moisture, thus accelerating the drying efficiency of the fabric.

[0022] The hot air blown out from the second air outlet 431 will remain between the upper and lower sides of the fabric, which can pre-dry the fabric before it passes through the drying component and supplement the drying of the fabric after it passes through the drying component, thereby improving the drying effect of the fabric. Moreover, part of the hot air remains between the upper and lower sides of the fabric, reducing the direct emission of hot air into the working environment and reducing the temperature rise of the working environment.

[0023] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
