Description

Technical Field

[0001] The invention relates to the technical field of drying, and in particular to a dyed cloth drying device and a drying process thereof. Background Art

[0002] After dyeing and printing the fabrics, the printing and dyeing factory needs to use the drying equipment for the dyed fabrics to facilitate the drying of the dyed fabrics. The existing dyed fabric drying equipment includes multiple pairs of heat-conducting rollers arranged in parallel up and down. The multiple pairs of heat-conducting rollers are arranged at intervals along the conveying direction of the dyed fabric as conveying rollers. When working, the dyed fabric is conveyed between the multiple pairs of heat-conducting rollers in parallel up and down, and the heat-conducting rollers are used to heat and dry the dyed fabric. However, during the drying process, the dyed fabric is easily damaged due to direct contact with the heat source. At the same time, the dyed fabric is sandwiched between the multiple pairs of heat-conducting rollers, which makes it easy for the dyed fabric to be excessively pulled during the winding process, causing wrinkles to appear on the dyed fabric. Summary of the invention

[0003] In order to overcome the deficiencies of the prior art, the present invention proposes a dyed cloth drying device and a drying process thereof, so as to solve the technical problem that the dyed cloth is easily damaged and wrinkled in the prior art.

[0005] A dyeing and drying device comprises a shell and a conveying roller extending in the left-right direction, the conveying roller is arranged on the shell and is used to convey the cloth in the front-back direction, the conveying roller comprises a heating roller and a ventilation cylinder located outside the heating roller, an annular ventilation space is provided between the ventilation cylinder and the heating roller, the outer wall of the ventilation cylinder is used to support the cloth from the lower side of the cloth, the conveying roller also comprises a turntable respectively fixed at both ends of the heating roller, and a circular inner tooth ring arranged on the shell, the inner tooth ring corresponds to the turntable one by one, the turntable is elliptical and is located inside the inner tooth ring, a flexible tooth ring is provided between the turntable and the inner tooth ring, the The flexible toothed ring is an elliptical ring coaxial with the turntable, and the flexible toothed ring can rotate relative to the turntable. The flexible toothed ring and the air tube are both flexible structures that can be deformed. The two ends of the air tube are respectively fixedly connected to the flexible toothed rings on the corresponding sides, and some teeth on the flexible toothed ring are meshed with the inner toothed ring. The turntable transmission is connected to a driving mechanism for driving the turntable to rotate. When the turntable rotates, the flexible toothed ring can be deformed and rotate in the inner toothed ring. The rotation speed of the flexible toothed ring is lower than the rotation speed of the turntable. The rotation of the flexible toothed ring drives the air tube to rotate synchronously, so as to drive the cloth placed on the air tube to move forward.

[0006] Furthermore, the shell is a box with an open upper end, and at least two conveying rollers are provided. At least two conveying rollers are arranged at intervals in the front-to-back direction at the opening of the box. When in use, the cloth is supported above each conveying roller, and the cloth blocks the opening at the upper end of the box.

[0007] Furthermore, the box body is a rectangular parallelepiped structure, the top end of the box body is the opening, and the width of the box body in the left-right direction is the same as the width of the cloth.

[0008] Furthermore, a hair dryer for blowing air into the interior of the box is provided on one side of the box, and the hair dryer is used to drive the gas in the box to pass through the cloth upward to dry the cloth.

[0009] Furthermore, a pressure rod assembly is provided above the box body, and the pressure rod assembly includes a hanging plate suspended directly above the box body, and an elastic pressure rod movably arranged on the lower side of the hanging plate. There are multiple elastic pressure rods, and the upper end of each elastic pressure rod is connected to the hanging plate, and the lower end of the elastic pressure rod is used for elastically pressing contact with the upper side of the cloth.

[0010] Furthermore, two conveying rollers are provided, and the two conveying rollers are respectively arranged at the front and rear ends of the box body. A plurality of elastic pressure rods are divided into two rows and arranged at the left and right sides of the hanging plate. Each row of elastic pressure rods is arranged between two conveying rollers at intervals along the front and rear directions. The two rows of elastic pressure rods are respectively used to press down the left and right edges of the cloth so that the left and right edges of the cloth are in contact and cooperate with the upper end of the box body.

[0011] Furthermore, the inner gear rings located at the left and right ends of each conveying roller are respectively fixedly mounted on the left and right side walls of the box, and are both located at the upper ends of the left and right side walls of the box. The top end of the inner gear ring is higher than the upper end of the box, so that the fabric above the air tube is flush with the upper end of the box when it is in the lowest position.

[0012] Furthermore, one axial end of each of the inner gear rings extends out of the box body, and a sealing plate is provided at one end of each of the inner gear rings extending out of the box body.

In the process of the driving mechanism driving the turntable to rotate, the breathable cylinder and the flexible gear ring rotate synchronously, and the breathable cylinder and the flexible gear ring are deformed together, and the breathable cylinder with an elliptical cross-section will reciprocate and rise and fall during the rotation process. When the top of the breathable cylinder rises, the cloth will be lifted up, and the cloth will be driven forward during the continuous rotation process, thereby achieving the effect of conveying the cloth forward. At the same time, in the process of the top of the breathable cylinder reciprocating up and down, the cloth will shake up and down, which can stretch the surface of the cloth on the one hand, and promote the hot air to pass through the cloth on the other hand, thereby improving the drying effect.

[0016] Furthermore, the shell is configured as a box, and a hair dryer is arranged on one side of the box. After the cloth is placed on the conveying roller, the upper end of the box is covered with the cloth, and the hot air will pass through the cloth upward as much as possible, which can improve the drying effect of the cloth.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] An embodiment of a dyeing cloth drying device of the present invention is as follows Figures 1 to 4 As shown, the dyeing cloth drying equipment includes a shell 300 and conveying rollers 200 extending in the left and right directions. The conveying rollers 200 are arranged on the shell 300. When in use, the cloth 100 is placed above each conveying roller 200 in the front-to-back direction. The conveying rollers 200 rotate to convey the cloth 100 above in the front-to-back direction. Here, the moving direction of the cloth 100 is defined as the front.

[0025] In the present invention, the conveying roller 200 includes a coaxially arranged heating roller 203 and a ventilation cylinder 205, the axes of the ventilation cylinder 205 and the heating roller 203 both extend in the left-right direction, and a plurality of ventilation holes are spaced apart on the ventilation cylinder 205, and the ventilation holes are evenly spaced along the axial direction of the ventilation cylinder 205. The ventilation cylinder 205 is located at the periphery of the heating roller 203, and there is an annular ventilation space between the ventilation cylinder 205 and the heating roller 203. When in use, the cloth 100 is supported on the outer wall of the ventilation cylinder 205, that is, the lower side of the cloth 100 is supported on the outer side wall of the ventilation cylinder 205, so that the cloth 100 does not directly contact the heating roller 203 (i.e., the heat source), but is dried by the hot air passing through the ventilation cylinder 205, thereby reducing damage to the cloth 100.

[0026] In the present invention, the conveying roller 200 further includes a turntable 202 respectively fixed at both ends of the heating roller 203, and a circular inner toothed ring 206 arranged on the housing 300. The inner toothed ring 206 corresponds to the turntable 202 one by one, and the turntable 202 is elliptical and located inside the inner toothed ring 206. A flexible toothed ring 204 is arranged between the turntable 202 and the inner toothed ring 206, and part of the teeth on the flexible toothed ring 204 mesh with the inner toothed ring 206, and the flexible toothed ring 204 is an elliptical ring coaxial with the turntable 202. The inner circumference of the flexible toothed ring 204 is tightly fitted with the outer circumference of the turntable 202, and the flexible toothed ring 204 can rotate relative to the turntable 202, and the flexible toothed ring 204 and the air-permeable tube 205 are both flexible structures that can be deformed. Both ends of the air-permeable cylinder 205 are fixedly connected to the flexible toothed rings 204 on the corresponding sides, and the rotating disk 202 is transmission-connected to a driving mechanism 201 for driving the rotating disk 202 to rotate.

[0027] In the present invention, when the driving mechanism 201 drives the turntable 202 to rotate, the turntable 202 and the heating roller 203 rotate together, and the flexible toothed ring 204 rotates relative to the turntable 202. During the rotation of the flexible toothed ring 204 relative to the turntable 202, the inner circumference of the flexible toothed ring 204 is always tightly fitted with the outer circumference of the turntable 202, so that the rotation of the elliptical turntable 202 can drive the flexible toothed ring 204 to deform, so that the teeth on the outer periphery of the flexible toothed ring 204 are meshed with the teeth on the inner toothed ring 206 in turn, so that the flexible toothed ring 204 can rotate in the inner toothed ring 206, and at the same time, the rotation speed of the flexible toothed ring 204 is less than the rotation speed of the turntable 202, so that the heating roller 203 rotates at a faster speed in the air permeable tube 205, while the air permeable tube 205 located on the periphery rotates at a slower speed. Since the flexible toothed ring 204 and the air cylinder 205 are both flexible structures capable of deformation, the air cylinder 205 will also rotate synchronously with the flexible toothed ring 204 during the rotation of the flexible toothed ring 204 relative to the turntable 202, and the air cylinder 205 will deform together with the flexible toothed ring 204. During the rotation of the air cylinder 205 with an elliptical cross section, the top of the air cylinder 205 will reciprocate and rise and fall. When the top of the air cylinder 205 rises, the cloth 100 will be lifted up, and the cloth 100 will be driven forward during the continuous rotation, thereby achieving the effect of conveying the cloth 100 forward.

[0028] In this embodiment, the housing 300 is a box with an upper opening, and at least two conveying rollers 200 are provided. At least two conveying rollers 200 are arranged at intervals at the opening of the box along the front-back direction. When in use, the cloth 100 is supported above each conveying roller 200, and the cloth 100 blocks the opening at the upper end of the box. The box is a rectangular parallelepiped structure, and the top of the box is the opening. The width of the box in the left-right direction is the same as the width of the cloth 100, so that after the cloth 100 is placed on the conveying rollers 200, the cloth 100 covers the entire opening at the upper end of the box. A hair dryer 500 for blowing air into the box is provided on one side of the box, and the hair dryer 500 can drive the hot air in the box to pass through the cloth 100 upward to dry the cloth 100. Since the upper end of the box is covered by the cloth 100, the hot air will pass through the cloth 100 upward as much as possible, which can improve the drying effect of the cloth 100.

[0029] In this embodiment, a pressure rod assembly 400 is provided above the box body, and the pressure rod assembly 400 includes a hanging plate 402 suspended directly above the box body, and an elastic pressure rod 401 movably arranged on the lower side of the hanging plate 402. There are multiple elastic pressure rods 401, and the upper end of each elastic pressure rod 401 is connected to the hanging plate 402, and the lower end of the elastic pressure rod 401 is used for elastically pressing contact with the upper side of the cloth 100.

[0030] In this embodiment, two conveying rollers 200 are provided, and the two conveying rollers 200 are respectively arranged at the front and rear ends of the box body. A plurality of elastic pressure rods 401 are divided into two rows and arranged at the left and right sides of the hanging plate 402 respectively. Each row of elastic pressure rods 401 is arranged between the two conveying rollers 200 at intervals along the front and rear direction. The two rows of elastic pressure rods 401 are respectively used to press down the left and right edges of the cloth 100 so that the left and right edges of the cloth 100 are in contact with the upper end of the box body. The inner tooth rings 206 located at the left and right ends of each conveying roller 200 are respectively fixedly installed on the left and right side walls of the box body, and are both located at the upper end positions of the left and right side walls of the box body. The top end of the inner tooth ring 206 is higher than the upper end of the box body, so that the cloth 100 above the air-permeable tube 205 is flush with the upper end position of the box body when it is at the lowest position.

[0031] In this embodiment, one axial end of each inner gear ring 206 extends out of the box body, and a sealing plate is provided at one end of each inner gear ring 206 extending out of the box body, and a through hole is provided on the sealing plate located on one side of the box body. The driving mechanism 201 is a driving motor, which is fixed on the sealing plate with a through hole, and the output shaft of the driving motor passes through the through hole to connect with the rotating disk 202.

[0032] A dyeing cloth drying process using the above dyeing cloth drying device, the dyeing cloth drying device is as follows Figures 1 to 4As shown, when in use, the cloth 100 is supported on the conveying rollers 200 in the front-to-back direction, the cloth 100 is supported on the surface of the air-permeable cylinder 205 of each conveying roller 200, and the pressing rod located above the cloth 100 elastically presses the left and right sides of the cloth 100. The heat generated by the heating rollers 203 in each conveying roller 200 dries the cloth 100 above through the air-permeable cylinder 205. At the same time, the heat of the heating rollers 203 also enters the box body, and the hot air in the box body can be urged to pass through the cloth 100 upward through the hair dryer 500 arranged on one side of the box body. At the same time, when the driving mechanism 201 drives the turntable 202 to rotate, the air cylinder 205 rotates synchronously with the flexible toothed ring 204, and the air cylinder 205 and the flexible toothed ring 204 are deformed together. During the rotation of the air cylinder 205 with an elliptical cross section, the top of the air cylinder 205 will reciprocate and rise and fall. When the top of the air cylinder 205 rises, the cloth 100 will be pushed up, and the cloth 100 will be driven forward during the continuous rotation, thereby achieving the function of conveying the cloth 100 forward. At the same time, during the reciprocating up and down lifting of the top of the air cylinder 205, the cloth 100 will shake up and down, which can stretch the surface of the cloth 100 on the one hand, and promote the hot air to pass through the cloth 100 on the other hand, thereby improving the drying effect.
