Abstract
Description
Technical Field
[0001] This utility model relates to the field of fabric processing technology, and in particular to a fabric drying device. Background Technology
[0002] When processing clothing fabrics, the fabrics must first be cleaned, and then dried before processing can begin.
[0003] CN117213198B discloses a prior art drying equipment for garment fabric processing, including a drying chamber, a drying mechanism, an air inlet chamber, air jet holes, an air pump, an air inlet pipe, and a pumping pipe. The drying chamber has an air inlet chamber at its lower end, and multiple air jet holes are opened at the top of the air inlet chamber. An air pump is fixedly connected to the lower end of the drying chamber, and an air inlet pipe is fixedly connected to the side wall of the air pump. The air pump is connected to the air inlet chamber through the pumping pipe. A leveling mechanism is also disclosed. The leveling mechanism includes a first sliding groove, a slider, a mounting bracket, a mounting block, a groove, a leveling block, a first spring, and a driving assembly. The first sliding groove is opened at the top of the drying chamber.
[0004] Existing leveling blocks use spring-driven sliders to clamp and level the fabric. In practice, it has been found that when the clamps are closed, airflow in the area where the fabric contacts the clamps is blocked, especially in the central area of the fabric where it is in a confined space, making it difficult for hot and humid air to escape. Simultaneously, the hot air from the blowing-type drying process creates localized vortices when the clamps are closed, causing moisture to remain between the fabric fibers, requiring extended drying time for evaporation and increasing energy consumption. Furthermore, the process of drying before leveling leads to separation of heat setting and mechanical setting, making the fabric prone to springback and wrinkling after cooling. Utility Model Content
[0005] The present invention mainly solves the technical problem that the humid air is difficult to evaporate during the fabric clamping and shaping process, and provides a fabric drying device.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a fabric drying device, comprising:
[0007] The frame is a supporting frame structure. The top of the frame has a channel for drying, and the inner wall of the frame has guide rollers for guiding the fabric. The guide rollers are rotatably connected to the frame.
[0008] A drying assembly, installed on the inner wall of the frame, is used for flattening and drying the fabric. The drying assembly includes an upper shaping box, a duct fan, a heating box, and ventilation holes. Both the upper shaping box and the heating box are hollow box structures. The upper shaping box is fixedly connected to the frame, and the heating box is flexibly connected to the frame. The heating box has a heating unit for heating air inside its cavity. Several ventilation holes are opened through the adjacent walls of the upper shaping box and the heating box. The duct fan is located above the upper shaping box and communicates with the cavity of the upper shaping box. The duct fan can exhaust the gas inside the cavity of the upper shaping box.
[0009] In a preferred embodiment of this utility model, the top of the upper shaping box forms an opening, and a cover plate fixed by bolts is provided at the opening of the upper shaping box. The cover plate covers and seals the opening, and the duct fan is fixedly installed on the cover plate.
[0010] In a preferred embodiment of this utility model, the drying assembly further includes side plates. A side plate is fixedly installed on each of the two side walls of the heating box. A vertical groove is provided on the inner wall of the frame. The side plates are slidably connected to the vertical grooves. A spring is fixedly installed at the bottom of the side plates to push the side plates to move upward.
[0011] In a preferred embodiment of this utility model, the drying assembly further includes notches, and several identical notches are provided on the top surface of the heating box and the bottom surface of the upper shaping box. The heating box and the upper shaping box form a wavy contact surface through the notches, and the fabric passes through the wavy surface between the upper shaping box and the heating box.
[0012] In a preferred embodiment of this utility model, the heating unit includes an air guide plate, an electric heating rod, and an upward channel. Several air guide plates are fixedly installed inside the heating chamber, and several electric heating rods are detachably installed at the bottom of each air guide plate. An upward channel is opened between two adjacent electric heating rods.
[0013] In a preferred embodiment of this utility model, the bottom of the heating box is open, and a base plate is provided at the bottom of the heating box. The base plate is locked to the heating box by screws, and the base plate has several rectangular windows for air intake.
[0014] In a preferred embodiment of this utility model, the air guide plate forms a rectangular plate structure, and the wall surface of the air guide plate is provided with several slots. The slots are arc-shaped, and two clamps are fixedly installed in the slots. The heating rod is inserted into the slot and clamped and fixed by the clamps. The rising channel forms a rectangular groove and passes through the air guide plate.
[0015] This utility model provides a fabric drying device. It has the following beneficial effects:
[0016] 1. This fabric drying device uses a duct fan to create negative pressure by venting gas from the upper setting chamber. This negative pressure draws air from between the upper setting chamber and the heating chamber into the upper setting chamber. Meanwhile, hot air from the heating chamber flows upwards through the fabric and is drawn into the upper setting chamber. This hot air heats and dries the fabric. The hot air entering the upper setting chamber also raises its temperature. By clamping the fabric between the upper setting chamber and the heating chamber, the fabric is held and shaped during the drying process, keeping it flat. This results in better drying and shaping effects, higher efficiency, and ensures the hot air is properly held in place. The flow of air further improves drying efficiency. By drawing air, hot air rises and passes through the fabric to achieve drying. Compared with the two opposing hot air methods in the existing technology, it can reduce the impact of humid hot air convection. The rising hot air carries away heat in a more physical way, which can achieve rapid drying of the fabric. During the heating and drying process, the fabric is continuously leveled and softened. Finally, it is squeezed and leveled again, which can greatly improve the leveling effect of the fabric and improve product quality. When hot air penetrates the fabric, the fibers are softened by heat. At this time, mechanical pressure shapes the fibers, achieving simultaneous "thermoplastic + mechanical pressing".
[0017] 2. This fabric drying device uses a spring to push the side plate to slide in the vertical groove, allowing the heating box to adjust the distance between itself and the upper shaping box to adapt to fabrics of different thicknesses. The elastically connected heating box, in conjunction with the upper shaping box, not only ensures the clamping and shaping effect on the fabric, but also ensures the smooth movement of the fabric between the upper shaping box and the heating box, preventing the fabric from being difficult to move due to excessive clamping force.
[0018] 3. This fabric drying device, by setting a notch, the notch being an arc-shaped groove, makes the surfaces of the upper shaping box and the heating box that are in contact with each other form a wavy surface, thereby increasing the surface area of the upper shaping box and the heating box, improving the heating effect on the fabric, and the fabric between the upper shaping box and the heating box forms a corresponding serpentine bend, the length of the fabric's movement trajectory is longer, and the time the fabric spends under the upper shaping box is extended, further improving the drying effect.
[0019] 4. In this fabric drying device, cold air enters the heating chamber through a rectangular window below the base plate, and is heated by an electric heating rod to a guide plate. The guide plate, with its upward channel, forms a grid shape, thus increasing the contact area between the cold air and the guide plate. The guide plate is placed at an angle to ensure that the cold air collides with the guide plate and is heated to form hot air, thereby improving the heating effect of the electric heating rod on the air.

[0027] A fabric drying device, such as Figure 1 As shown, it includes:
[0028] The frame 10 is a supporting frame structure. The top of the frame 10 is provided with a drying channel. The inner wall of the frame 10 is provided with guide rollers 11 for guiding the fabric. The guide rollers 11 are rotatably connected to the frame 10. Specifically, two guide rollers 11 are arranged as a group. Two groups of guide rollers 11 are provided on the wall of the frame 10. The two groups of guide rollers 11 are respectively installed near the two side ports of the frame 10 for introducing and exporting the fabric.
[0029] like Figure 2 , Figure 3 and Figure 4As shown, the drying assembly, installed on the inner wall of the frame 10, is used for flattening and drying the fabric. The drying assembly includes an upper shaping box 20, a duct fan 21, a heating box 22, and ventilation holes 24. Both the upper shaping box 20 and the heating box 22 are hollow box structures. The upper shaping box 20 is fixedly connected to the frame 10, and the heating box 22 is elastically connected to the frame 10. The heating box 22 has a heating unit inside for heating air. Several ventilation holes 24 are opened through the adjacent walls of the upper shaping box 20 and the heating box 22. The duct fan 21 is located above the upper shaping box 20 and communicates with its chamber. The duct fan 21 can exhaust the gas inside the upper shaping box 20. An opening is formed at the top of the upper shaping box 20. The opening of the upper shaping box 20 is provided with a cover plate fixed by bolts, which covers and seals the opening. The duct fan 21 is fixedly installed on the cover plate. In this solution, the gas in the upper shaping box 20 cavity is discharged by the duct fan 21 to form a negative pressure, and then the air between the upper shaping box 20 and the heating box 22 is drawn into the upper shaping box 20. Then the hot air in the heating box 22 flows upward through the fabric and is drawn into the upper shaping box 20. The hot air passes through the fabric to heat and dry the fabric. The hot air entering the upper shaping box 20 will also cause the upper shaping box 20 to heat up. The fabric is clamped by the upper shaping box 20 and the heating box 22, and the fabric is clamped and shaped during the drying process, so that the fabric remains flat. The drying and shaping effect of the fabric is better and the efficiency is higher.
[0030] like Figure 3 As shown, the drying assembly also includes side plates 23. A side plate 23 is fixedly installed on each of the two side walls of the heating box 22. A vertical groove is opened on the inner wall of the frame 10. The side plates 23 are slidably connected to the vertical groove. A spring is fixedly installed at the bottom of the side plate 23 to push the side plate 23 to move upward. The side plate 23 is pushed to slide in the vertical groove by the spring, so that the heating box 22 can adjust the distance between itself and the upper shaping box 20 to adapt to fabrics of different thicknesses. The elastically connected heating box 22, together with the upper shaping box 20, can ensure the effect of clamping and shaping the fabric, and also ensure the smooth movement of the fabric between the upper shaping box 20 and the heating box 22, so as not to make the fabric difficult to move due to excessive clamping force.
[0031] like Figure 4As shown, the drying assembly also includes notches 25. Several identical notches 25 are opened on the top surface of the heating box 22 and the bottom surface of the upper shaping box 20. The heating box 22 and the upper shaping box 20 form a wavy contact surface through the notches 25. The fabric passes through the wavy surface between the upper shaping box 20 and the heating box 22. By setting the notches 25, which are arc-shaped slots, the surfaces of the upper shaping box 20 and the heating box 22 that are in contact with each other form a wavy surface, which increases the surface area of the upper shaping box 20 and the heating box 22, improving the heating effect on the fabric. The fabric between the upper shaping box 20 and the heating box 22 forms a corresponding serpentine bend, which is longer and prolongs the time the fabric passes under the upper shaping box 20. The hot air generates a Venturi effect along the curved surface of the notches, which increases the flow rate and accelerates the removal of moisture, further improving the drying effect.
[0032] like Figure 5 and Figure 6 As shown, the heating unit includes an air guide plate 30, heating rods 31, and an upward channel 32. Several air guide plates 30 are fixedly installed inside the heating chamber 22. Several heating rods 31 are detachably installed at the bottom of each air guide plate 30. An upward channel 32 is formed between two adjacent heating rods 31. The bottom of the heating chamber 22 is open, and a base plate is provided at the bottom of the heating chamber 22. The base plate is locked to the heating chamber 22 by screws. Several rectangular windows for air intake are provided on the base plate. The air guide plates 30 form a rectangular plate structure. Several slots are provided on the wall surface of the air guide plates 30. The slots are arc-shaped, and two clamping pieces are fixedly installed in the slots. The heating rods 31 are inserted into the slots and clamped and fixed by the clamping pieces. The upward channel 32 forms a rectangular groove. 2. Through the air guide plate 30, as a supplement to the above scheme, cold air enters the heating box 22 through the rectangular window below the bottom plate and heats the air guide plate 30 through the electric heating rod 31. With the air guide plate 30 having an upward channel 32, the air guide plate 30 forms a grid shape, so that the cold air has a larger contact surface with the air guide plate 30. Secondly, the air guide plate 30 is placed at an angle, that is, the air guide plate 30 extends at an angle from the bottom to the top of the heating box 22, ensuring that the cold air collides with the air guide plate 30 and is heated to form hot air, which can improve the heating effect of the electric heating rod 31 on the air. After the cold air enters through the rectangular window of the bottom plate, it impacts the surface of the air guide plate to form turbulence, and the heat exchange efficiency is improved compared with the vertical plate.
[0033] The duct fan 21 and the electric heating rod 22 need to be connected to a controller and a power supply for use.
[0034] The working principle of this utility model is as follows: The duct fan 21 discharges the gas in the upper shaping box 20 cavity to form a negative pressure, thereby drawing the air between the upper shaping box 20 and the heating box 22 into the upper shaping box 20. The hot air in the heating box 22 then flows upward through the fabric and is drawn into the upper shaping box 20. The hot air heats and dries the fabric. A spring pushes the side plate 23 to slide within the vertical groove, allowing the heating box 22 to adjust its distance from the upper shaping box 20. A notch 25, which is an arc-shaped groove, is provided, creating a wavy surface where the upper shaping box 20 and the heating box 22 meet, increasing their surface area. After the fabric passes through the notch 25... The fabric is fully and evenly heated. After entering the upper shaping box 20 and the shaping plate on the side of the heating box 22 through the opening 25, it is squeezed and shaped to achieve flatness, which improves the heating effect on the fabric. Cold air enters the heating box 22 through the rectangular window below the bottom plate and heats the air guide plate 30 through the electric heating rod 31. With the air guide plate 30 with the opening of the rising channel 32, the air guide plate 30 forms a grid shape, so that the cold air has a larger contact surface with the air guide plate 30. In addition, the air guide plate 30 is placed at an angle, that is, the air guide plate 30 extends at an angle from the bottom to the top of the heating box 22, ensuring that the cold air collides with the air guide plate 30 and is heated to form hot air. The hot air is discharged from the ventilation hole 24 and blown towards the fabric.
