[0033] Example 1

[0034] like Figure 1-5 As shown, the present invention proposes a waterproof roll polyester base fabric drying device, which includes a shell 1, a drying component 2, a fan 3, an air conveying pipe 4 and a guide roller 5;

[0035] There are two drying components 2. The two drying components 2 are symmetrically installed inside the housing 1 and are fixed by bolts during installation. The position of the drying components 2 inside the housing 1 can be adjusted to a safe distance that is closest to the polyester base fabric. When the polyester base fabric passes through the drying components 2, the drying components 2 directly heat and dry the polyester base fabric.

[0036] There are multiple guide rollers 5, and all guide rollers 5 are arranged on the side of the housing 1. Multiple air outlets 6 are provided on the surface of the guide rollers 5.

[0037] The air supply pipe 4 is installed at one end of the housing 1 and communicates with the housing 1, and the other end passes through multiple guide rollers 5 and is inserted into the middle of multiple guide rollers 5. The air supply pipe 4 and the guide rollers 5 are rotatably installed, so that the guide rollers 5 rotate on the outside of the air supply pipe 4 after being installed through the bearing seat.

[0038] The fan 3 is installed at the other end of the housing 1 and is connected to the housing 1, so that the fan 3 delivers air to the back of the drying assembly 2.

[0039] In this embodiment, the polyester base fabric is moved towards the inside of the housing 1 by the guidance of multiple guide rollers 5. During the movement, the drying assembly 2 is activated to heat the air inside the housing 1. The air heated on the back of the drying assembly 2 is then transported to the air duct 4 by the fan 3. At the same time, the drying assembly 2 heats the air transported by the fan 3, and the air duct 4 transports the hot air to the inside of the guide rollers 5. The hot air inside the guide rollers 5 is blown onto the polyester base fabric through the air outlet 6, allowing the polyester base fabric to undergo drying. The polyester base fabric is also pre-dried simultaneously by multiple guide rollers 5. The polyester base fabric is then wound up between two drying assemblies 2, allowing the two drying assemblies 2 to directly dry the polyester base fabric. This results in high drying efficiency, good drying effect, and reduced drying energy consumption.

[0040] Example 2

[0041] like Figure 1-2 As shown, the present invention proposes a waterproof roll polyester base fabric drying device. Compared with Embodiment 1, in this embodiment, the drying component 2 includes a heating wire 21 and a mounting plate 23.

[0042] Mounting plate 23 is installed on the inner side of housing 1 and is connected to housing 1 with a sealed cavity, the sealed cavity being located on the back of mounting plate 23;

[0043] Heating wire 21 is installed on one side of mounting plate 23.

[0044] In an optional embodiment, through holes 7 are provided at both ends of the housing 1 and at the sealed cavity ends located between the mounting plate 23 and the housing 1, which are connected to the cavity. The fan 3 and the air supply pipe 4 are connected to the sealed cavity through the through holes 7 so that when in use, the fan 3 drives the air to move from the through holes 7 into the cavity and delivers it to the air supply pipe 4 through the cavity. During the movement of the air in the cavity, the heating wire 21 heats it.

[0045] It should be noted that a number of reinforcing ribs 22 are provided on one side of the mounting plate 23, and a number of heat-conducting plates 24 extending into the sealed cavity are provided on the other side of the mounting plate 23. The length direction of the heat-conducting plates 24 is the same as the length direction of the shell 1. During the movement of air inside the cavity, it comes into contact with the multiple heat-conducting plates 24 and the mounting plate 23, thereby improving the air heating efficiency.

[0046] In this embodiment, the heating wire 21 is activated to conduct heat through the mounting plate 23 and the heat-conducting plate 24, thereby heating the air inside the housing 1. The heat is then conducted through the sealed cavity between the mounting plate 23 and the housing 1, and the air inside the cavity is heated by the heat conducted through the mounting plate 23 and the heat-conducting plate 24. This causes the fan 3 to deliver air into the cavity through the through hole 7 and to deliver the hot air into the air duct 4. At the same time, the hot air delivered by the fan 3 comes into contact with the mounting plate 23 and the heat-conducting plate 24 for heating, so that the inside of the air duct 4 is continuously supplied with hot air.

[0047] Example 3

[0048] like Figure 1-2 As shown, the waterproof roll polyester base fabric drying device proposed in this utility model, compared with the first embodiment, in this embodiment, the air supply pipe 4 includes a connector 41, a pipe body 42 and an air outlet 43.

[0049] The connector 41 is installed at the other end of the housing 1 and communicates with the housing 1. It should be noted that the inner diameter of the connector 41 gradually decreases from the end of the housing 1 toward the end of the tube 42 along the length direction of the housing 1. This is used to accumulate a large amount of hot air inside the connector 41 during use, so that the connector 41 has pressure when delivering hot air and improves the hot air delivery speed.

[0050] The tube body 42 is installed at one end of the connector 41, and the other end extends toward the guide roller 5 and is inserted into the plurality of guide rollers 5;

[0051] There are multiple air outlets 43, which are located on the outside of the pipe body 42 and on the inside of the guide roller 5. When in use, the air outlets 43 can be selected to deliver gas using a nozzle or a smaller pipe body.

[0052] In this embodiment, the shape of the connector 41 allows the hot air inside the housing 1 to be pressurized when it is transported to the inside of the tube 42 through the restriction of the connector 41, thereby increasing the air transport speed of the tube 42. The pressurized hot air is then transported to the inside of the roller 51 through multiple air outlets 43 and, after filling the inside of the guide roller 5, is pressurized and transported to the polyester base fabric through the air outlet 6, so that the hot air heats and dries the polyester base fabric.

[0053] Example 4

[0054] like Figure 1-2 As shown, the waterproof roll polyester base fabric drying device proposed in this utility model, compared with the first embodiment, in this embodiment, the guide roller 5 includes roller body 51, bearing 52, bolt 54 and connecting plate 55;

[0055] The roller body 51 is hollow tubular in shape, and multiple air outlets 6 are evenly distributed on the outer circular surface of the roller body 51 and the middle part of the roller body 51.

[0056] There are two connecting plates 55. The ends of the connecting plates 55 are provided with grooves. The end of the roller body 51 is inserted into the groove of the connecting plate 55 and connected to the connecting plate 55. The connecting plates 55 are used to seal and support the end of the roller body 51 during use. The roller body 51 is inserted into the connecting plate 55 by bolts 54, so that the bolts 54 are threadedly connected to the connecting plate 55 and the roller body 51 is fixedly connected to the connecting plate 55.

[0057] The bearing 52 is installed in the middle of the connecting plate 55 and sleeved on the outside of the air duct 4.

[0058] In an optional embodiment, a plurality of annular ribs 53 are provided on the inner side of the roller body 51 and between the plurality of air outlets 6 to support the inner side of the roller body 51 during use and prevent dents from occurring during use.

[0059] In this embodiment, the connecting plate 55 drives the roller body 51 to be installed and fixed through the bearing seat, so that the connecting plate 55 is rotatably connected to the bearing seat through the bearing, and the connecting plate 55 is rotatably connected to the air conveying pipe 4 through the bearing 52, so that the roller body 51 and the air conveying pipe 4 have a sealing effect. When the air conveying pipe 4 conveys the container to the inside of the roller body 51, it can only be discharged to the outside of the air outlet 6 through the air outlet 6.

[0060] In summary, when this utility model is in use, the polyester base fabric is moved from the outside of the roller body 51 towards the middle of the housing 1, causing the polyester base fabric to drive the roller body 51 and the bearing seat of the connecting plate 55 to rotate. The roller body 51 assists in the movement of the polyester base fabric, and heating is activated by the heating wire 21. The mounting plate 23 and the heat-conducting plate 24 conduct heat, simultaneously heating the air inside the housing 1. The heat is also conducted through the sealed cavity between the mounting plate 23 and the housing 1, and the heat inside the cavity is heated by the heat conducted by the mounting plate 23 and the heat-conducting plate 24. The fan 3 continuously delivers air into the cavity through the through hole 7 and delivers the hot air into the pipe body 42. At the same time, the hot air delivered by the fan 3 comes into contact with the mounting plate 23 and the heat-conducting plate 24 for heating. The hot air is continuously supplied to the tube 42. Due to the shape of the connector 41, the hot air inside the shell 1 is supplied to the inside of the tube 42 under pressure. The pressurized air is supplied to the roller 51 through the air outlet 43. The inside of the roller 51 is filled due to the fast speed of the hot air supply. The roller 51 supplies hot air to the polyester base fabric through the air outlet 6. The hot air preheats and dries the polyester base fabric. Under the guidance of the roller 51, the polyester base fabric moves into the shell 1 and is wound between the two heating wires 21. When passing through the heating wires 21, the heating wires 21 directly contact the polyester base fabric, resulting in a high drying efficiency for the polyester base fabric.

[0061] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
