Description

Technical Field

[0001] This utility model relates to the field of textile fabric processing equipment technology, and more specifically, to a textile fabric drying device. Background Technology

[0002] After textile fabrics are dyed, they need to be dried quickly. This removes absorbed moisture and helps fix the dye in the dye bath, ensuring the dyeing effect. Currently, existing textile fabric dryers use a combination of a drying chamber and a heating fan for online drying. During operation, the dyed and dehydrated fabric is drawn through the drying chamber, and high-temperature hot air generated by the hot air blower is discharged from the bottom of the chamber. The fabric is dried as the hot air rises. However, due to structural limitations, existing textile fabric dryers can only blow hot air from the hot air blown onto the top or bottom surface of the fabric, resulting in uneven drying and low drying efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a textile fabric drying device that can improve the drying efficiency of fabrics and improve the uniformity of fabric drying.

[0004] This utility model provides a textile fabric drying device, including a drying chamber, a lid, a hot air supply device, and a drive mechanism. The lid is connected to the upper end of the drying chamber, the hot air supply device is fixed to the outer bottom of the drying chamber, and the drive mechanism is connected to the rear outer wall of the drying chamber. Channels for fabric to pass through are provided on both the left and right side walls of the drying chamber. Several air nozzles are spaced apart along the length of the fabric in the drying chamber above and below the fabric. The air outlet of each nozzle faces the fabric, and the distance between each nozzle and the fabric is... Each end is equipped with a guide pipe running from front to back. The outer circumferential wall of each guide pipe is welded and fixed to the air nozzle and circumferentially sealed. The inner cavity of each air nozzle is connected to the corresponding guide pipe. Both ends of each guide pipe are rotatably connected to the drying chamber. The rear end of each guide pipe is closed and connected to the drive mechanism. The front end of each guide pipe is connected to the air outlet of the hot air supply device and rotatably connected. The drive mechanism is used to drive the guide pipe to rotate back and forth so that the guide pipe drives the air nozzle to swing left and right. Several air outlet holes are arranged in an array on the left and right side walls of the drying chamber.

[0005] By adopting the above-described structure, the air nozzles located above and below the fabric can blow hot air from the hot air supply device onto the upper and lower surfaces of the fabric, thereby improving the drying efficiency and uniformity of the fabric. Furthermore, since the air nozzles located above and below the fabric can swing left and right, the uniform drying of the fabric can be further achieved.

[0006] In one possible implementation, a main air supply pipe is connected to the outlet of the hot air supply device, and a corresponding branch air supply pipe is connected to the main air supply pipe. The front end of each branch air supply pipe is rotatably connected to the outlet of the corresponding branch air supply pipe through a rotary joint and circumferentially sealed. With this structure, the branch air supply pipe can be reliably connected to the outlet of the hot air supply device through the branch air supply pipe and the main air supply pipe. That is, the hot air supply device can reliably deliver hot air to the branch air supply pipe through the main air supply pipe and the branch air supply pipe. Under the action of the rotary joint, while ensuring the connection between the branch air supply pipe and the branch air supply pipe, the rotation of the branch air supply pipe relative to the branch air supply pipe can also be ensured. That is, when the drive mechanism drives the branch air supply pipe to rotate back and forth, the rotation of the branch air supply pipe relative to the outlet of the hot air supply device can be ensured.

[0007] In one possible implementation, the drive mechanism includes a drive unit and two slide plates spaced vertically apart. Both slide plates are connected to the rear outer wall of the drying chamber and can slide left and right relative to the drying chamber. The drive unit is fixed to the rear outer wall of the drying chamber and drives the two slide plates to slide left and right relative to the drying chamber. Each air duct has an eccentrically fixed swing arm at its rear end. The upper slide plate is movably connected to the swing arm at the rear end of the air duct above the fabric, and the lower slide plate is movably connected to the swing arm at the rear end of the air duct below the fabric. When the slide plates slide left and right relative to the drying chamber, the slide plates drive the air ducts to rotate reciprocally via the swing arms. With this drive mechanism, when the drive mechanism drives the two slide plates to slide left and right relative to the drying chamber, under the transmission connection between the slide plates and the swing arms, each slide plate can drive the corresponding air duct to rotate reciprocally via the corresponding swing arm. This allows the air ducts to drive the nozzles to rotate reciprocally, so that the nozzles can evenly blow hot air onto the upper and lower surfaces of the fabric to achieve fabric drying.

[0008] In one possible implementation, each slide plate is provided with several elongated holes that correspond one-to-one with the swing arms on the corresponding side. Each elongated hole extends vertically, and each swing arm has a rod extending in the front-back direction fixed at the end away from the air guide tube. Each rod is inserted into one of the elongated holes of the corresponding slide plate and slides in cooperation with the elongated hole. With this structure, since the rod slides in cooperation with the elongated hole, when the slide plate slides left and right relative to the drying chamber, the air guide tube can be reliably driven to reciprocate and rotate through the rod and the swing arm, thereby enabling the air guide tube to reliably drive the air nozzle to swing left and right.

[0009] In one possible implementation, the drive unit includes a bracket, a stepper motor, and a gear. The bracket is fixed to the rear outer wall of the drying chamber, the stepper motor is fixed to the bracket, and the gear is coaxially fixed to the output shaft of the stepper motor. The stepper motor drives the gear to reciprocate. The gear is located between two sliding plates. Each sliding plate has a rack portion in the middle of its side facing the gear, and both rack portions mesh with the gear. By using this drive unit, under the cooperation of the gear and rack portions, when the stepper motor drives the gear to reciprocate, the two sliding plates can reliably slide back and forth relative to the drying chamber. The sliding directions of the two sliding plates are opposite at the same time, that is, the air nozzles above the fabric and the air nozzles below the fabric swing in opposite directions at the same time. This allows the air nozzles above and below the fabric to blow hot air onto the fabric more evenly to dry the fabric.

[0010] In one possible implementation, two slide rails are fixed on the rear outer wall of the drying chamber, which are spaced vertically apart. Both slide rails extend in the left-right direction, and each slide plate can be slidably connected to one of the slide rails. With this structure, both slide plates can be reliably slidably connected to the drying chamber by the slide rails at corresponding positions.

[0011] In one possible implementation, a plurality of support roller groups are connected to the inner wall of the drying chamber, which are spaced apart along the length of the fabric. Each support roller group includes two support rollers that abut against the upper and lower surfaces of the fabric, respectively. Both ends of each support roller in the axial direction are rotatably connected to the inner wall of the drying chamber. By setting up a plurality of support roller groups, the plurality of support roller groups can reliably support the fabric located inside the drying chamber and can guide the fabric.

[0012] In one possible implementation, the rear side of the lid is rotatably connected to the rear side of the upper end of the drying chamber via several hinges spaced apart from left to right, and the front side of the lid is locked to the front side of the upper end of the drying chamber via several latching components spaced apart from left to right. With this structure, when the latching components are unlocked, the lid can be opened relative to the drying chamber via the hinges, which facilitates the maintenance of the air nozzles located inside the chamber. After the air nozzles are maintained, the lid can be put back on the drying chamber and the lid and the drying chamber can be re-locked by the latching components. Attached Figure Description

[0017] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] See Figures 1-5 As shown in the figure, this application discloses a textile fabric drying device, including a drying chamber 1, a chamber cover 2, a hot air supply device 3, and a drive mechanism; the chamber cover 2 is connected to the upper end of the drying chamber 1, the hot air supply device 3 is fixed to the outer bottom of the drying chamber 1, and the drive mechanism is connected to the rear outer wall of the drying chamber 1. Channels 11 for the fabric 4 to pass through are provided on both the left and right side walls of the drying chamber 1. Several air nozzles 5 are provided in the drying chamber 1 above and below the fabric 4, spaced apart along the length of the fabric 4. The air outlet of each air nozzle 5 faces the fabric 4, and each air nozzle 5 is far from the fabric. One end of each material 4 is provided with an air guide pipe 6 from front to back. The outer peripheral wall of each air guide pipe 6 is welded and fixed to the air nozzle 5 and circumferentially sealed. The inner cavity of each air nozzle 5 is connected to the corresponding air guide pipe 6. Both ends of each air guide pipe 6 are rotatably connected to the drying chamber 1. The rear end of each air guide pipe 6 is closed and connected to the drive mechanism. The front end of each air guide pipe 6 is connected to the air outlet of the hot air supply device 3 and rotatably connected. The drive mechanism is used to drive the air guide pipe 6 to rotate back and forth so that the air guide pipe 6 drives the air nozzle 5 to swing left and right. Several air outlet holes 12 are provided on the left and right side walls of the drying chamber 1 in an array.

[0019] The hot air supply device 3 has a main air supply pipe 7 connected to its outlet. The main air supply pipe 7 has a corresponding air supply branch pipe 71 connected to the air guide pipe 6. The front end of each air guide pipe 6 is rotatably connected to the outlet end of the corresponding air supply branch pipe 71 through a rotary joint 61 and is circumferentially sealed. With this structure, the air guide pipe can be reliably connected to the outlet of the hot air supply device through the air supply branch pipe and the main air supply pipe. That is, the hot air supply device can reliably deliver hot air to the air guide pipe through the main air supply pipe and the air supply branch pipe. Under the action of the rotary joint, while ensuring the connection between the air guide pipe and the air supply branch pipe, the rotation of the air guide pipe relative to the air supply branch pipe can also be ensured. That is, when the drive mechanism drives the air guide pipe to rotate back and forth, the rotation of the air guide pipe relative to the outlet of the hot air supply device can be ensured.

[0020] The drive mechanism includes a drive unit and two slide plates 81 spaced vertically apart. Both slide plates 81 are connected to the rear outer wall of the drying chamber 1 and can slide left and right relative to the drying chamber 1. The drive unit is fixed to the rear outer wall of the drying chamber 1 and drives the two slide plates 81 to slide left and right relative to the drying chamber 1. Each air duct 6 has an eccentrically fixed swing arm 62 at its rear end. The upper slide plate 81 is movably connected to the swing arm 62 at the rear end of the air duct 6 above the fabric 4, and the lower slide plate 81 is connected to the air duct 6 below the fabric 4. The swing arm 62 at the rear end is movably connected; when the slide plate 81 slides left and right relative to the drying chamber 1, the slide plate 81 drives the air duct 6 to rotate back and forth via the swing arm 62; by adopting this drive mechanism, when the drive mechanism drives the two slide plates to slide left and right relative to the drying chamber, under the action of the transmission connection between the slide plate and the swing arm, each slide plate can drive the corresponding air duct to rotate back and forth via the corresponding swing arm, so that the air duct drives the air nozzle to rotate back and forth, so that the air nozzle can evenly blow hot air to the upper and lower surfaces of the fabric to achieve the drying of the fabric.

[0021] Each slide plate 81 is provided with several elongated holes 811 that correspond one-to-one with the swing arms 62 on the corresponding side. Each elongated hole 811 extends vertically. Each swing arm 62 has a fixed insert rod 621 extending in the front-back direction at the end away from the air guide tube 6. Each insert rod 621 is inserted into one of the elongated holes 811 of the corresponding slide plate 81 and slides in cooperation with the elongated hole 811. With this structure, since the insert rod slides in cooperation with the elongated hole, when the slide plate slides left and right relative to the drying box, the air guide tube can be reliably driven to reciprocate and rotate through the insert rod and the swing arm, thereby enabling the air guide tube to reliably drive the air nozzle to swing left and right.

[0022] The drive unit includes a bracket 82, a stepper motor 83, and a gear 84. The bracket 82 is fixed to the rear outer wall of the drying chamber 1, the stepper motor 83 is fixed to the bracket 82, and the gear 84 is coaxially fixed to the output shaft of the stepper motor 83. The stepper motor 83 drives the gear 84 to reciprocate. The gear 84 is located between two sliding plates 81. Each sliding plate 81 has a rack portion 812 in the middle of the side facing the gear 84, and both rack portions 812 mesh with the gear 84. By adopting this drive unit, under the cooperation of the gear and rack portion, when the stepper motor drives the gear to reciprocate, the two sliding plates can reliably slide back and forth relative to the drying chamber. The sliding directions of the two sliding plates are opposite at the same time. That is, the air nozzles above the fabric and the air nozzles below the fabric swing in opposite directions at the same time. This allows the air nozzles above and below the fabric to blow hot air onto the fabric more evenly to dry the fabric.

[0023] Two slide rails 13 are fixed on the rear outer wall of the drying chamber 1, which are spaced vertically. Both slide rails 13 extend in the left and right direction, and each slide plate 81 can be slidably connected to one of the slide rails 13. With this structure, both slide plates can be reliably slidably connected to the drying chamber by the slide rails at corresponding positions.

[0024] The inner wall of the drying chamber 1 is connected to several support roller groups that are spaced apart along the length of the fabric 4. Each support roller group includes two support rollers 14 that abut against the upper and lower surfaces of the fabric 4, respectively. Both ends of each support roller 14 in the axial direction are rotatably connected to the inner wall of the drying chamber 1. Through the arrangement of several support roller groups, the support roller groups can reliably support the fabric located inside the drying chamber and guide the fabric.

[0025] The rear side of the lid 2 is rotatably connected to the rear side of the upper end of the drying chamber 1 by a number of hinges 21 spaced from left to right. The front side of the lid 2 is locked to the front side of the upper end of the drying chamber 1 by a number of latching components 22 spaced from left to right. With this structure, when the latching components are unlocked, the lid can be opened relative to the drying chamber by the hinges, which facilitates the maintenance of the air nozzles located inside the chamber. After the air nozzles are maintained, the lid can be put back on the drying chamber and the lid and the drying chamber can be locked again by the latching components.

[0026] In operation, the dyed fabric continuously enters the drying chamber through the channel on the left side and exits through the channel on the right side. As the fabric passes through the drying chamber, hot air from the hot air supply device is blown onto the upper and lower surfaces of the fabric via nozzles located above and below it, improving drying efficiency and uniformity. Furthermore, the nozzles above and below the fabric swing left and right under the drive mechanism, further enhancing the uniform drying effect.

[0027] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
