Description

Technical Field

[0001] This application relates to the field of dryers, and more particularly to a dryer for drying polyester fabrics. Background Art

[0002] Polyester, also known as polyester fiber, is a high molecular compound and the most important type of synthetic fiber. It has excellent wrinkle resistance and shape retention and is often used to make clothing.

[0003] Polyester fabrics are produced using penetration printing technology, which involves heat transfer printing, drying, steaming, and finishing. The dryer is used to dry the polyester fabrics.

[0004] Currently, utility model patent CN207439077U discloses a polyester fiber dyeing and drying machine, including a drying box, a storage box at the top of the drying box, a circulating fan fixedly installed inside the storage box, the air outlet of the circulating fan fixedly connected to the top of the air conveying pipe, the bottom end of the air conveying pipe passing through the storage box and communicating with the interior of the drying box, two rows of rollers inside the drying box, and several electric heating plates evenly arranged at the bottom of the inner wall of the drying box. This utility model enables more uniform heating during the dyeing of polyester fibers.

[0005] Due to the distribution of rollers inside the drying chamber, the fabric can be conveyed along a zigzag pattern inside the drying chamber. A rectangular drying chamber can better facilitate the distribution of rollers. However, a drying chamber with a constant internal space requires more heat to achieve uniform internal temperature, which also results in low heat utilization. Utility Model Content

[0006] In order to improve the utilization rate of heat in the drying oven, this application provides a dryer for drying polyester fabrics.

[0007] This application provides a dryer for drying polyester fabrics, which adopts the following technical solution:

[0008] A dryer for drying polyester fabric includes a drying chamber, several drying rollers, and several compression components for reducing the internal space of the drying chamber. The drying rollers are distributed in a zigzag pattern, and the compression components are located between two adjacent drying rollers at the same height. Each compression component includes a sliding plate, two rotating plates, two mating plates, and a driving component. The sliding plate is vertically slidably connected to the inside of the drying chamber. One side of each of the two rotating plates is rotatably connected to opposite sides of the sliding plate. The two mating plates correspond one-to-one with the two rotating plates and are rotatably connected to the other side of each rotating plate. The mating plates are horizontally slidably connected to the inside of the drying chamber. The sliding plate, the two sliding plates, and the two rotating plates form a sealed space. The driving component is used to move the sliding plate.

[0009] By adopting the above technical solution, when the fabric is being dried in the drying chamber, the operator can adjust the space inside the drying chamber through the compression component. The operator activates the drive component to bring the sliding plate closer to the fabric. The sliding plate drives two rotating plates to rotate, and the rotating plates drive the corresponding mating plates to move. At this time, the sealed space gradually increases. Since the heat of the drying chamber cannot enter the sealed space, the actual drying area of ​​the drying chamber is reduced, thus improving the heat utilization rate inside the drying chamber. During the process of feeding the fabric into the drying chamber, the operator can activate the drive component to move the sliding plate in the opposite direction. The sliding plate drives the rotating plates to rotate, and the rotating plates drive the mating plates to move, thus reducing the sealed space and increasing the space inside the drying chamber, which facilitates the operator's feeding operation.

[0010] Optionally, the driving component includes a drive motor and a drive screw. The length direction of the drive screw is parallel to the sliding direction of the sliding plate. The drive screw is rotatably connected inside the drying chamber, and the drive motor drives the drive screw to rotate.

[0011] By adopting the above technical solution, when the staff needs to move the sliding plate, the drive motor can be started. The drive motor drives the drive screw to rotate, and the drive screw drives the sliding plate to slide on the drying box. The drive screw can be adjusted precisely and has a self-locking effect, so the position of the sliding plate remains stable.

[0012] Optionally, the compression assembly further includes a heat insulation layer, which is laid on the sliding plate, the rotating plate, and the mating plate.

[0013] By adopting the above technical solution, when the sliding plate moves, the volume of the sealed space increases, and the contact area between the sliding plate, rotating plate, and mating plate and the heat inside the drying oven is increased compared to the original contact area of ​​the drying oven. The heat insulation layer can reduce the heat transfer to the sealed space through the sliding plate, rotating plate, and mating plate, thereby improving the heat utilization rate.

[0014] Optionally, the drying oven has a balance hole on its side wall that communicates with the sealed space.

[0015] By adopting the above technical solution, the driving component is used to move the sliding plate to change the volume of the sealed space. Since the sealed space is not connected to the inside of the drying oven, the balance hole is used to maintain the air pressure stability of the sealed space and improve the driving effect of the driving component.

[0016] Optionally, openings for fabric conveying are provided on opposite side walls of the drying chamber. The drying chamber is equipped with a sealing assembly to reduce heat escape from the openings. The sealing assembly includes two sealing plates, two rotating rollers, and two driving components. The two sealing plates are located on opposite sides of the fabric and are slidably connected to the drying chamber. The two rotating rollers are rotatably connected to the two sealing plates and are used to abut against the fabric. The two driving components are used to drive the sealing plates to move.

[0017] By adopting the above technical solution, an opening is made for the fabric to pass through, and some heat will escape from the opening. The sealing component can further reduce the heat escape. After the fabric is fed, the operator can drive the drive component, which drives the two sealing plates to move closer to each other until the sealing plates and the rotating rollers of the two sealing plates abut against the fabric. The sealing plates and the rotating rollers reduce the heat escape from the opening, and the rotating rollers can be used to guide the fabric and reduce the occurrence of the fabric contacting the side wall of the opening.

[0018] Optionally, the driving component includes a driving cylinder, which is disposed on the drying chamber and is used to drive the sealing plate to move.

[0019] By adopting the above technical solution, the position of the sealing plate is changed by the extension and contraction of the piston rod of the cylinder. The operation of the cylinder is convenient and the structure is reasonable.

[0020] Optionally, the drying oven is further provided with an air supply assembly, which includes an air supply box, a circulation pipe, a fan, and a heating rod. The air supply box is located on the drying oven and is connected to the drying oven. The fan is located inside the air supply box, the heating rod is located inside the drying oven, one end of the circulation pipe is located on the air supply box, and the other end of the circulation pipe is located on the drying oven.

[0021] By adopting the above technical solution, when the fabric in the drying box needs to be dried, the staff starts the fan and heating rod. The heating rod increases the heat in the air supply box, and the fan transfers the heat in the air supply box to the drying box. The air in the drying box enters the air supply box through the circulation pipe, and the air supply box heats the cold air again. The air supply component is used to transfer heat to the drying box so that the fabric can be dried.

[0022] Optionally, the air supply box and the circulation pipe are connected to one end of the drying box along the transport direction of the fabric.

[0023] By adopting the above technical solution, the hot air in the air supply box enters the drying box, and then enters the circulation pipe from the drying box. The heat transfer route in the drying box is consistent with the fabric transfer route. The fabric gradually changes from wet to dry. The air supply components are more rationally distributed, making the heat utilization more efficient.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The compression component is used to reduce the space inside the drying oven and improve the utilization rate of heat inside the drying oven;

[0026] 2. The sealing component is used to seal the opening of the drying oven to reduce heat loss from the opening;

[0027] 3. The air supply unit is used to supply air to the inside of the drying chamber, so that the heat of the hot air can dry the fabric. Attached Figure Description
