Description

Technical Field

[0001] This utility model relates to the field of polyester production technology, and in particular to a continuous drying device for polyester production. Background Technology

[0002] Polyester fabrics require washing during the production process. Specifically, polyester fabrics typically need to be washed during dyeing or conventional wet treatment. The purpose of washing is to remove loose dye and other impurities from the fabric to ensure colorfastness. Additionally, washing can adjust the fabric's pH value, keeping it within the standard range.

[0003] After drying, polyester fabrics may still have excessively high moisture content due to variations in fabric thickness and moisture content. Existing drying equipment maintains the same height as the fabric and cannot adjust the hot air drying intensity according to the humidity of different areas of the fabric. Therefore, drying equipment needs to adjust the drying intensity according to the moisture content of different areas of the fabric to ensure the drying effect of polyester fabrics. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a continuous drying device for polyester production.

[0005] This utility model is achieved through the following technical solution:

[0006] A continuous drying device for polyester production includes an oven, a fan, clamps, heating pipes, a protective net, a lifting mechanism, and an adjusting assembly. The fan is installed on the top of the oven, the clamps are located inside the top of the oven, the heating pipes are clamped inside the clamps, the protective net and the lifting mechanism are located inside the oven, and the adjusting assembly is located outside the oven. The lifting mechanism includes a fixed plate, a first cylinder, a lifting frame, a flattening roller, and a guide strip. The fixed plate is fixedly located inside the oven, the first cylinder is installed at the bottom of the fixed plate, the lifting frame is located at the extension end of the first cylinder, the flattening roller is movably connected to the inner top of the lifting frame, and the guide strip is fixedly located inside the back of the oven.

[0007] In a preferred embodiment of the present invention, the adjustment assembly includes a fixed frame, a second cylinder, a mounting block, a synchronous roller, and a humidity sensor. The second cylinder is fixedly disposed at the bottom of the fixed frame, the mounting block is fixedly disposed at the telescopic end of the second cylinder, the synchronous roller is movably connected to the mounting block, and the humidity sensor is disposed on the surface of the synchronous roller.

[0008] The main function of the adjustment component is to measure the humidity of the fabric entering the drying oven and adjust the height of the synchronous roller and the flattening roller according to the fabric humidity, so that the distance between the fabric and the heating tubes in the drying oven can be adjusted in real time.

[0009] In a preferred embodiment of this utility model, conveying holes are provided on both sides of the drying oven to facilitate the transfer of fabric, and an air inlet is provided on the top of the drying oven to cooperate with the air inlet of the fan.

[0010] The fan introduces high-speed airflow into the drying oven, and under the heating of the heating tubes, the airflow acts on the surface of the fabric, thereby achieving the drying effect.

[0011] In a preferred embodiment of this utility model, a guide groove is provided on the inner side of the guide bar, and both ends of the lifting frame are engaged in the guide groove on the inner side of the guide bar;

[0012] The guide bar not only provides effective guidance for the movement of the lifting frame, but also ensures that the lifting frame moves vertically.

[0013] In a preferred embodiment of this utility model, the protective net is disposed on the outer side of the bottom of the heating tube.

[0014] In a preferred embodiment of this utility model, an auxiliary fixing rod is provided on the outside of the fan, and the bottom of the auxiliary fixing rod on the outside of the fan is fixed to the top of the oven;

[0015] The auxiliary fixing rods on the outside of the fan not only facilitate the installation of the fan, but also effectively improve the operational stability of the fan.

[0016] The beneficial effects of this utility model are:

[0017] This continuous drying device for polyester production is mainly used when the polyester fabric still has a high moisture content after the initial drying. Before the fabric enters the drying oven, the humidity sensor detects the humidity of different areas of the fabric in real time, and adjusts the distance between the fabric and the heating tube according to the fabric humidity, thereby controlling the airflow and heating temperature. While the flattening roller adjusts the height of the fabric, the adjusting component adjusts the height of the synchronous roller simultaneously to avoid the fabric being overly tense or loose due to the adjustment of the flattening roller height.

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0024] like Figure 1-4 The continuous drying device for polyester production shown includes an oven 1, a fan 2, a clamp 3, a heating tube 4, a protective net 5, a lifting mechanism 6, and an adjusting component 7. The fan 2 is installed on the top of the oven 1, the clamp 3 is located on the inner side of the top of the oven 1, the heating tube 4 is clamped in the clamp 3, the protective net 5 and the lifting mechanism 6 are located inside the oven 1, and the adjusting component 7 is located on the outer side of the oven 1. The lifting mechanism 6 includes a fixed plate 61, a first cylinder 62, a lifting frame 63, a flattening roller 64, and a guide strip 65. The fixed plate 61 is fixedly located on the inner side of the oven 1, the first cylinder 62 is installed at the bottom of the fixed plate 61, the lifting frame 63 is located at the telescopic end of the first cylinder 62, the flattening roller 64 is movably connected to the inner side of the top of the lifting frame 63, and the guide strip 65 is fixedly located on the inner side of the back of the oven 1.

[0025] Specifically, the adjustment assembly 7 includes a fixed frame 71, a second cylinder 72, a mounting block 73, a synchronous roller 74, and a humidity sensor 75. The second cylinder 72 is fixedly installed at the bottom of the fixed frame 71, the mounting block 73 is fixedly installed at the telescopic end of the second cylinder 72, the synchronous roller 74 is movably connected to the mounting block 73, the humidity sensor 75 is installed on the surface of the synchronous roller 74, the oven 1 has conveying holes on both sides to facilitate the transfer of fabric, the oven 1 has an air inlet hole on the top that cooperates with the air inlet end of the fan 2, the guide bar 65 has a guide groove on the inner side, the lifting frame 63 is locked at both ends in the guide groove on the inner side of the guide bar 65, the protective net 5 is installed on the outer side of the bottom of the heating tube 4, the fan 2 has an auxiliary fixing rod on the outer side, and the bottom of the auxiliary fixing rod on the outer side of the fan 2 is fixed to the top of the oven 1.

[0026] In this embodiment, the pre-dried polyester fabric passes through the bottom of the synchronous roller 74 and then through the top of the flattening roller 64. During the drying process, the fan 2 inputs high-speed airflow into the oven 1. After being heated by the heating tube 4, the airflow acts on the surface of the polyester fabric, thereby achieving the drying effect. The heating tube 4 is connected to the inner top of the oven 1 by the clamp 3. The protective net 5 prevents the fabric from getting too close to the heating tube 4 and being damaged.

[0027] Furthermore, before entering the drying oven 1, the polyester fabric first passes through the synchronous roller 74, and the surface of the synchronous roller 74 is equipped with a humidity sensor 75. When the humidity sensor 75 detects that the fabric humidity is too high, the distance between the fabric and the heating tube 4 needs to be shortened to improve the drying effect. At this time, the first cylinder 62 at the bottom of the fixed plate 61 extends and lifts the lifting frame 63, thereby lifting the fabric with the flattening roller 64. At this time, the guide strip 65 guides and controls the vertical movement of the lifting frame 63, and the distance between the fabric surface and the heating tube 4 is shortened, thereby achieving a more ideal drying process. However, the lifting of the synchronous roller 74 by the first cylinder 62 causes the fabric to be stretched instantly, which may cause excessive stretching of the fabric. Therefore, the second cylinder 72 rises synchronously to reduce the tension on the fabric and ensure the quality of the fabric. Similarly, when the lifting frame 63 descends, the fabric will relax, and the second cylinder 72 controls the synchronous roller 74 to descend, pressing down on the fabric to maintain the fabric tension.
