Description

Technical Field

[0001] This application relates to the technical field of textile machinery, and in particular to a polyester fabric drying device. Background Technology

[0002] Polyester fabric is a synthetic fiber fabric made of polyester fibers, chemically known as polyethylene terephthalate (PET), which is the commercial name for polyester fiber in my country. It is produced through spinning and post-processing, and possesses characteristics such as high strength, good abrasion resistance, wrinkle resistance, and dimensional stability. After dyeing, polyester fabric generally requires drying to remove moisture and prevent fiber deformation or defects caused by excessive humidity in subsequent processes.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN219244180U, which discloses a polyester fabric drying device for textile production, including a conveyor belt, a gantry at one end of the conveyor belt, a first roller at the lower end of the gantry, a second roller at the lower end of the first roller, a U-shaped plate at the lower end of the second roller, a circular groove through one side of the gantry, a water pipe at one side of the gantry, a motor at the upper end of the water pipe, a drying box in the middle of the conveyor belt, a fan at the top of the drying box, a hot air fan at one side of the drying box, an air duct at the lower end of the hot air fan, an air hopper inside the drying box, an electric heating wire mesh at the lower end of the air hopper, a conveyor cylinder at the lower end of the electric heating wire mesh, an inner cylinder at the axis of the conveyor cylinder, and heat dissipation holes on the surface of both the conveyor cylinder and the inner cylinder.

[0004] However, when the aforementioned drying device uses a hot air blower to dry the surface of polyester fabric, impurities that adhere to the surface of the fabric when it is wet will be dispersed into the drying chamber with the hot air after the fabric is dried, and will accumulate in the drying chamber after long-term operation. These impurities not only easily have an adverse effect on other fabric transmission equipment in the drying chamber, but also easily adhere to the fabric that subsequently enters the drying chamber, thus causing secondary pollution to the fabric. Utility Model Content

[0005] In order to reduce the probability of impurities accumulating in the drying oven having an adverse effect on fabric production, this application provides a polyester fabric drying device.

[0006] This application provides a polyester fabric drying device, which adopts the following technical solution: A polyester fabric drying device includes a frame and a drying chamber mounted on the frame. A hot air blower is installed on the drying chamber. A conveying device is installed on the frame, through which the fabric enters and exits the drying chamber. A waste removal device is installed on the frame to remove accumulated impurities from the drying chamber. The waste removal device includes: An outlet box is mounted on the frame and located below the drying chamber. A waste discharge pipe is located on the top of the waste discharge box and communicates with the inside of the waste discharge box. A guiding mechanism is provided on the drying chamber and is used to guide impurities in the drying chamber into the impurity outlet pipe.

[0007] By adopting the above technical solution, the conveying device sends the fabric into the drying box, and the hot air fan in the drying box starts to blow air and dry the fabric. Impurities on the fabric are blown to the bottom of the drying box by the hot air fan. The guiding mechanism guides the impurities into the impurity discharge pipe. After passing through the impurity discharge pipe, the impurities enter the impurity discharge box for centralized collection and treatment, thereby completing the treatment of impurities in the drying box and reducing the probability that impurities will accumulate in the drying box and adversely affect the drying and subsequent output quality of the fabric.

[0008] Optionally, the guiding mechanism includes: A first guide cylinder is mounted on the frame; An air inlet pipe, one end of which is located on the outer wall of the bottom of the drying chamber and communicates with the inside of the drying chamber, and the other end of which is connected to the outer wall of the first guide cylinder and communicates with the inside of the first guide cylinder; The second guide cylinder is disposed at the bottom of the first guide cylinder. The second guide cylinder is conical in shape, and its cross-sectional area gradually decreases from top to bottom. The outlet tube is disposed at the bottom of the second guide cylinder and communicates with the inside of the second guide cylinder, and the bottom of the outlet tube is communicated with the impurity outlet tube; An air outlet pipe is provided at the top of the first guide cylinder and communicates with the inside of the first guide cylinder. The air outlet pipe is located at the center of the top surface of the first guide cylinder. A filter assembly, which is designed on the air outlet duct and is used to filter the gas discharged from the air outlet duct.

[0009] By adopting the above technical solution, the air inlet pipe guides the gas discharged from the drying chamber, along with impurities, into the first guide cylinder. After entering the first guide cylinder, the gas and impurities move along the inner wall of the first guide cylinder and then into the second guide cylinder. The airflow containing impurities rotates at high speed in the second guide cylinder, using centrifugal force to throw the denser dust particles towards the wall of the chamber, and then using gravity to make them settle into the outlet pipe and enter the impurity outlet pipe for collection in the impurity outlet box. When the airflow reaches the bottom of the second guide cylinder, the airflow contracts and flows towards the center, forming an inner vortex. The purified gas is discharged from the top through the air outlet pipe. The filter assembly performs secondary filtration on the low-density impurities in the gas discharged from the air outlet pipe, thereby completing the work of exporting and collecting impurities in the drying chamber.

[0010] Optionally, the filtering component includes: The mounting frame is disposed on the air outlet duct, and the mounting frame has horizontal sliding holes. A filter plate, wherein the filter plate is slidably inserted into a sliding hole in the mounting frame; A limiting component is provided on the mounting frame and is used to limit the position of the filter plate within the sliding hole.

[0011] By adopting the above technical solution, an installation frame is installed on the air outlet duct, the filter plate is inserted into the sliding hole of the installation frame, and then the filter plate is fixed in place by a limiting component. This completes the installation of the filter plate on the air outlet duct. The filter plate can be removed from the installation frame for replacement by unlocking the limiting component, thus ensuring the filtration effect of the filter plate.

[0012] Optionally, the limiting member includes: The limiting block has a vertical moving groove on the inner top wall of the sliding hole, and the limiting block is slidably disposed on the moving groove; A limiting spring is provided. A vertical limiting groove is provided on the end surface of the filter plate. The limiting spring is set on the bottom wall of the moving groove and connected to the limiting block. Under the action of the limiting spring, the limiting block extends out of the moving groove and is inserted into the limiting groove. A pull rod is vertically slidably mounted on the mounting frame, with its top end positioned above the mounting frame and its bottom end extending into the moving groove and connecting to the limiting block.

[0013] By adopting the above technical solution, when the filter plate needs to be replaced, the pull rod is pulled upwards. The movement of the pull rod causes the limiting block to compress the limiting spring and move upwards. The limiting block moves upwards and disengages from the limiting groove on the filter plate. After the limiting block disengages from the limiting groove, the filter plate can be moved out of the mounting frame. Then, the new filter plate is inserted into the sliding hole of the mounting frame. The pull rod is released, and the limiting block, under the action of the limiting spring, partially extends out of the sliding groove and engages with the limiting groove to complete the filter frame replacement. The structure is simple and the operation is convenient.

[0014] Optionally, an arc-shaped guide surface is provided on the side wall of the bottom end of the limiting block near the outer wall of the mounting frame.

[0015] By adopting the above technical solution, an arc-shaped guide surface is opened at the bottom of the limiting block. When the moving filter plate enters the sliding hole, the filter plate will first contact the guide surface. The guide surface will generate a component force to drive the limiting block into the moving groove. Therefore, it is not necessary to manually pull the pull rod to drive the limiting block to disengage from the limiting groove, which simplifies the work steps and improves work efficiency.

[0016] Optionally, the conveying device includes: A conveyor rod is rotatably mounted on the frame. Several conveyor rods are provided, and the several conveyor rods are evenly distributed on the frame along the direction of entering and exiting the drying chamber. A drive mechanism is mounted on the frame and is used to drive the conveyor rod to rotate synchronously.

[0017] By adopting the above technical solution, several conveying rods are rotatably installed on the frame, and then the drive mechanism is started to drive the conveying rods to rotate. The rotation of the conveying rods can drive the fabric to move, thereby completing the conveying of the fabric.

[0018] Optionally, the drive mechanism includes: Two drive wheels, both of which are rotatably mounted on the frame and located on opposite sides of the drying chamber in the horizontal direction; A drive motor, which is mounted on the frame and connected to one of the two drive wheels; A transmission belt is fitted onto two drive wheels and its surface is pressed against several conveyor rods.

[0019] By adopting the above technical solution, the drive motor starts and drives the drive wheel to rotate. The rotation of the drive wheel drives the transmission belt to rotate, and the rotation of the transmission belt drives several conveyor rods to rotate. Thus, the rotation of the conveyor rods is achieved by controlling the drive motor.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The fabric is fed into the drying chamber by a conveying device. The hot air blower in the drying chamber is activated to blow air and dry the fabric. Impurities on the fabric are blown to the bottom of the drying chamber by the hot air blower. The guide mechanism guides the impurities into the impurity discharge pipe. After passing through the impurity discharge pipe, the impurities enter the impurity discharge box for centralized collection and treatment. This completes the treatment of impurities in the drying chamber and reduces the probability that impurities will accumulate in the drying chamber and adversely affect the drying and subsequent output quality of the fabric. 2. By installing an installation frame on the air outlet duct, inserting the filter plate into the sliding hole of the installation frame, and then using the limiting piece to limit the filter plate, the installation of the filter plate on the air outlet duct can be completed. Unlocking the limiting piece allows the filter plate to be removed from the installation frame for replacement, thus ensuring the filtration effect of the filter plate. 3. The drive motor starts and drives the drive wheel to rotate. The rotation of the drive wheel drives the transmission belt to rotate, and the rotation of the transmission belt drives several conveyor rods to rotate. Thus, the rotation of the conveyor rods is achieved by controlling the drive motor. Attached Figure Description

The rotation of the transmission belt 25 drives several conveyor rods 21 to rotate. The rotation of the conveyor rods 21 drives the fabric to move, thus completing the fabric conveying work. After the fabric is fed into the drying chamber 11, the hot air fan 12 in the drying chamber 11 starts to blow air and dry the fabric.

[0031] Reference Figure 2The air inlet pipe 35 guides the gas discharged from the drying chamber 11, along with impurities, into the first guide cylinder 34. After entering the first guide cylinder 34, the gas and impurities move along the inner wall of the first guide cylinder 34 and then into the second guide cylinder 36. The airflow containing impurities rotates at high speed in the second guide cylinder 36, using centrifugal force to throw the denser dust particles toward the wall of the chamber, and then using gravity to make them settle into the outlet pipe 37 and enter the impurity outlet pipe 32 for collection through the impurity outlet box 31. When the airflow reaches the bottom of the second guide cylinder 36, the airflow contracts and flows toward the center, forming an inner vortex. The purified gas is discharged from the top through the air outlet pipe 38.

[0032] Reference Figure 2 and Figure 4 A filter assembly 39 is disposed on the air outlet duct 38 and is used to filter the gas discharged from the air outlet duct 38.

[0034] Reference Figure 4 When the filter plate 42 needs to be replaced, pull the lever 46 to move it upward. The movement of the lever 46 causes the limiting block 44 to compress the limiting spring 45 and move it upward. The limiting block 44 moves upward and disengages from the limiting groove 48 on the filter plate 42. After the limiting block 44 disengages from the limiting groove 48, the filter plate 42 can be moved out of the mounting frame 41 to replace the filter plate 42.

The air inlet pipe 35 guides the gas and impurities in the drying chamber 11 into the first guide cylinder 34. After entering the first guide cylinder 34, the gas and impurities move along the inner wall of the first guide cylinder 34 and move into the second guide cylinder 36. The airflow containing impurities rotates at high speed in the second guide cylinder 36. Using centrifugal force, the denser dust particles are thrown towards the wall of the chamber. Then, with the help of gravity, they settle into the outlet pipe 37 and enter the impurity outlet pipe 32 for collection through the impurity outlet box 31. When the airflow reaches the bottom of the second guide cylinder 36, the airflow contracts and flows towards the center, forming an inner vortex. The purified gas is discharged from the top through the air outlet pipe 38. Impurities enter the discharge box 31 after passing through the discharge pipe 32 for centralized collection and treatment, thereby completing the treatment of impurities in the drying box 11 and reducing the probability that impurities will accumulate in the drying box 11 and adversely affect the drying and subsequent output quality of the fabric.
