Description

Technical Field

[0001] This invention relates to the field of drying equipment technology, and in particular to a drying equipment for breathable, leather-like coated mesh fabric. Background Technology

[0002] Breathable, leather-like coated mesh fabric drying equipment is mainly used to remove moisture from fabrics, ensuring they reach the specified moisture regain rate, preventing mildew, and meeting storage and transportation requirements. Industrial dryers are suitable for large-scale production environments, employing a hot air circulation system to achieve efficient drying through forced circulation heating and dehumidification, and also feature high-temperature sterilization. Coating dryers are designed for fibers and fabrics after printing, dyeing, or coating processes, using infrared radiation heating technology to simultaneously fuse the surface and underlying layers of ink, avoiding bubbling and discoloration problems caused by traditional heating methods. Fabric drying machines are mainly used for drying cotton greige fabrics and fabrics from water-jet looms, using steam drying cylinders to regulate the moisture regain rate and ensure the fabric is suitable for storage and transportation.

[0003] Existing drying equipment often results in incomplete drying of mesh fabrics due to poor ventilation at the support points and uneven distribution of drying airflow during the fabric conveying process. Summary of the Invention

[0004] To overcome the technical defects of the existing technology, the present invention provides a breathable, leather-like coated mesh drying device to ensure thorough drying.

[0005] The technical solution adopted in this invention is:

[0006] A breathable, leather-like coated mesh fabric drying device includes a conveyor belt, an insulated box, a circulation system, a heater, a distribution box, and an airflow distributor. The conveyor belt includes a conveyor frame, two drying chains, several drying support plates, several adaptive support devices, several fabric end fixing devices, several drying conveyor rollers, and a drying conveyor motor. The conveyor frame passes through the insulated box. The adaptive support devices are mounted on the upper side of the drying support plates. The head of the mesh fabric hooks onto the fabric end fixing device, which is mounted on both sides of the drying support plate. Each drying conveyor roller is rotatably mounted on the conveyor frame. Each drying conveyor roller has a high position and a low position, with a gap between the high-position drying conveyor roller and the low-position drying conveyor roller. The unit is configured with the following configuration: the drying conveyor motor is mounted on the conveyor frame and is connected to the drying conveyor roller; two drying chains pass around both ends of each drying conveyor roller; each drying support plate is mounted parallel to each other on the drying chains; the circulation system is mounted on the upper side of the insulation box; the heater is mounted on the insulation box and at the end of the circulation system; the distribution box is mounted below the heater and is connected to the heater via a hot air conveying pipe; the airflow distributor is rotatably mounted inside the distribution box, with its upper end adapted to the hot air conveying pipe; the airflow distributor has several rotating jet pipes, each of which is symmetrical about the rotation axis of the airflow distributor.

[0007] Preferably, the adaptive support device includes two adaptive support rollers arranged in pairs, each of which is mounted on a corresponding drying support plate via a swing rod, and the swing rods connecting the two adaptive support rollers are distributed in a figure-eight shape.

[0008] Preferably, the fabric end fixing device is a fixing pin.

[0009] Preferably, the insulated box includes an insulated base and an insulated top cover. The insulated top cover is hinged to the insulated base, and an opening cylinder is hinged to the insulated top cover. The output end of the opening cylinder is hinged to the insulated base.

[0010] Preferably, the circulation system includes a circulating fan, an air inlet hood, and a return air duct. The air inlet hood and the return air duct are both installed on the insulation box. The heater is installed at the end of the return air duct. The air inlet hood and the return air duct are respectively installed at the output port and the input port of the circulating fan.

[0011] Preferably, the heater is provided with a plurality of steam heating tubes.

[0012] Preferably, the bottom of the distribution box is provided with several spray outlets.

[0013] Preferably, the airflow distributor has a rounded bottom and a pointed top. The hot gas delivery pipe has a rotating bracket inside to press down the top of the airflow distributor, and the rotating bracket has a blind hole to press down the top of the airflow distributor.

[0014] The beneficial effects of this invention are:

[0015] The conveyor belt includes a conveyor frame, two drying chains, several drying support plates, several adaptive support devices, several fabric head fixing devices, several drying conveyor rollers, and a drying conveyor motor. The conveyor frame passes through the insulated box. The adaptive support devices are installed on the upper side of the drying support plates. When conveying the mesh fabric, the mesh fabric is placed on each adaptive support device and then conveyed with each adaptive support device. The head of the mesh fabric hooks onto the fabric head fixing device to prevent the mesh fabric from shifting. When the mesh fabric is driven through the lower side of the distribution box, the mesh fabric is subjected to downward pressure by the downward airflow of the airflow distributor. As the mesh fabric passes through, the adaptive support devices change the position of supporting the mesh fabric due to the change in downward pressure of the mesh fabric, ensuring uniform drying. The fabric head fixing devices are installed on both sides of the drying support plates and hook onto the beginning and end of the fabric to prevent the mesh fabric from drooping to the lower side of the drying support plates and slipping off.

[0016] Each drying conveyor roller is rotatably mounted on the conveyor frame. Each roller has a high position and a low position, with the high-position and low-position rollers spaced apart. During fabric conveying, the fabric passes sequentially through the high-position and low-position rollers, causing the fabric to periodically move closer to or away from the distribution box. The drying conveyor motor is mounted on the conveyor frame and is connected to the drying conveyor rollers via chains. Two drying chains pass around both ends of each drying conveyor roller, driving them to rotate synchronously. Each drying support plate is mounted parallel to the drying chains. The circulation system is installed on the upper side of the insulation box, and the heater is installed on the insulation box at the end of the circulation system. The distribution box is installed below the heater, and the distribution box is connected to the heater via hot air. The airflow distributor is rotatably installed in the distribution box, with its upper end adapted to the hot gas delivery pipe. The airflow distributor has several rotating jet pipes, each symmetrically positioned relative to the rotation axis of the airflow distributor. The rotation of the airflow distributor causes the high-temperature airflow to be rapidly ejected towards the end of the distribution box, ensuring uniform distribution of the hot gas. The direction of each rotating jet pipe does not pass through the rotation axis of the airflow distributor, allowing the airflow distributor to rotate when it ejects gas. The upper side of the airflow distributor has an air inlet connected to the corresponding rotating jet pipe. The distance between the upper side of the airflow distributor and the hot gas delivery pipe is less than 2 mm, thus restricting the hot gas from being ejected between the upper side of the airflow distributor and the hot gas delivery pipe. This allows the hot gas in the hot gas delivery pipe to be ejected downwards from the rotating jet pipe through the air inlet, thereby driving the airflow distributor to rotate.

[0033] The present invention will be further described below with reference to the accompanying drawings:

[0034] like Figure 1 — Figure 8 As shown, this embodiment provides a breathable, leather-like coated mesh drying device, including a conveyor belt 1, an insulated box 2, a circulation system 3, a heater 4, a distribution box 5, and an airflow distributor 6. The conveyor belt 1 includes a conveyor frame 11, two drying chains 12, several drying support plates 13, several adaptive support devices 14, several fabric head fixing devices 15, several drying conveying rollers 16, and a drying conveying motor. The conveyor frame 11 passes through the insulated box 2, and the adaptive support devices 14 are installed on the upper side of the drying support plates 13. When conveying the mesh fabric, the mesh fabric is placed on each adaptive support device 14 and then follows each adaptive support device 14. The adaptive support device 14 conveys the mesh fabric, and the head of the mesh fabric hooks onto the fabric head fixing device 15 to prevent the mesh fabric from shifting. When the mesh fabric is driven through the lower side of the distribution box 5, the mesh fabric is subjected to downward pressure by the downward airflow of the airflow distributor 6. The adaptive support device 14 changes the position of the mesh fabric as the mesh fabric passes through due to the change in the downward pressure of the mesh fabric, ensuring uniform drying. The fabric head fixing device 15 is installed on both sides of the drying support plate 13. The fabric head fixing device 15 hooks onto the beginning and end of the fabric to prevent the mesh fabric from drooping to the lower side of the drying support plate 13 and slipping off.

[0035] Each drying conveyor roller 16 is rotatably mounted on the conveyor frame 11. Each drying conveyor roller 16 has a high position and a low position, with the high-position drying conveyor roller 16 and the low-position drying conveyor roller 16 spaced apart. When the mesh fabric is conveyed, it passes sequentially through the high-position drying conveyor roller 16 and the low-position drying conveyor roller 16, thereby causing the mesh fabric to periodically move closer to or away from the distribution box 5. The mesh fabric experiences greater airflow pressure when it is close to the distribution box 5, and less airflow pressure when it is far from the distribution box 5. The drying conveyor motor is mounted on the conveyor frame 11 and is connected to the drying conveyor roller 16 via a chain. Two drying chains 12 pass around the two ends of each drying conveyor roller 16, and the two drying chains 12 drive each drying conveyor roller 16 to rotate synchronously. Each drying support plate 13 is mounted parallel to each other on the drying chains 12. The circulation system 3 is mounted on the upper side of the insulation box 2, and the heater 4 is mounted on the insulation box 2. The heater 4 is mounted at the end of the circulation system 3. 5 is installed on the lower side of the heater 4. The distribution box 5 is connected to the heater 4 through the hot gas delivery pipe 7. The airflow distributor 6 is rotatably installed in the distribution box 5. The upper end of the airflow distributor 6 is adapted to the hot gas delivery pipe 7. The airflow distributor 6 has several rotating jet pipes 61. Each rotating jet pipe 61 is symmetrical about the rotation axis of the airflow distributor 6. The rotation of the airflow distributor 6 causes the high-temperature airflow to be sprayed out quickly to the end of the distribution box 5, ensuring uniform distribution of hot gas. The direction of each rotating jet pipe 61 does not pass through the rotation axis of the airflow distributor 6, so that the airflow distributor 6 can rotate when it sprays gas. The upper side of the airflow distributor 6 has an air inlet 62 that is connected to the corresponding rotating jet pipe 61. The distance between the upper side of the airflow distributor 6 and the hot gas delivery pipe 7 is less than 2 mm, which restricts the hot gas from being sprayed out from the upper side of the airflow distributor 6 and the hot gas delivery pipe 7. This allows the hot gas in the hot gas delivery pipe 7 to be sprayed out downward from the rotating jet pipe 61 through the air inlet 62, thereby driving the airflow distributor 6 to rotate.

[0036] Specifically, the adaptive support device 14 includes two adaptive support rollers 141 arranged in pairs. Each adaptive support roller 141 is mounted on the corresponding drying support plate 13 via a swing rod 142. The swing rods 142 connected to the two adaptive support rollers 141 are distributed in a figure-eight shape. The swing rods 142 are made of spring steel sheets. When the mesh fabric is pushed downward by the airflow pressure, the swing rods 142 deform under the downward pressure, and the two adaptive support rollers 141 change their support position on the fabric to ensure uniform drying.

[0037] Specifically, the fabric end fixing device 15 is a fixing pin at the end of the mesh fabric. The mesh fabric hangs down naturally under the action of gravity, thus hooking the fixing pin and preventing the mesh fabric from slipping off.

[0038] Specifically, the insulation box 2 includes an insulation base 21 and an insulation top cover 22. The insulation top cover 22 is hinged to the insulation base 21. An opening cylinder 23 is hinged to the insulation top cover 22. The output end of the opening cylinder 23 is hinged to the insulation base 21 to open the insulation top cover 22 for easy maintenance.

[0039] Specifically, the circulation system 3 includes a circulating fan 31, an air inlet hood 32, and a return air duct 33. The air inlet hood 32 and the return air duct 33 are both installed on the insulation box 2. The heater 4 is installed at the end of the return air duct 33. The air inlet hood 32 and the return air duct 33 are respectively installed at the output port and the input port of the circulating fan 31 to realize the recovery of heat for heating.

[0040] Specifically, heater 4 is equipped with several steam heating tubes, which heat the air to achieve drying.

[0041] Specifically, the bottom of the distribution box 5 is provided with several nozzles 51 to ensure the uniform distribution of hot air.

[0042] Specifically, the airflow distributor 6 has a rounded head at the bottom and a pointed corner at the top. The hot air delivery pipe 7 has a rotating bracket 71 that presses down on the top of the airflow distributor 6. The rotating bracket 71 has a blind hole that presses down on the top of the airflow distributor 6, which provides a limit for the rotation of the airflow distributor 6.
