[0019] like Figures 1 to 5 As shown, a drum-type continuous dryer includes a casing 1, inside which a support plate 11 is fixedly installed. The support plate 11 divides the interior of the casing 1 into two drying chambers 2. Each of the two drying chambers 2 has a drying cylinder 21 arranged at an incline. Each of the two drying chambers 2 is provided with a limiting mechanism 3 for limiting the drying cylinder 21. The two limiting mechanisms 3 can limit the two drying cylinders 21 respectively. Since the two drying cylinders 21 are arranged at an incline, the fabric can pass through the two drying cylinders 21 respectively. The fabric can be dried multiple times by using the two drying cylinders 21.

[0020] The limiting mechanism 3 includes two limiting frames 31 and two limiting frames 32. The two limiting frames 31 are symmetrically arranged and fixed at the bottom of the drying chamber 2. The limiting frame 32 is fixed at the top of the drying chamber 2. The two limiting frames 31 and the two limiting frames 32 are rotatably connected to limiting wheels 33. The limiting wheels 33 abut against the outer wall of the drying cylinder 21. The setting of the three limiting wheels 33 can limit the drying cylinder 21 without affecting the rotation of the drying cylinder 21.

[0021] Two drive mechanisms 4 are provided outside the housing 1, both used to drive the drying drum 21 to rotate. The drive mechanism 4 includes a bracket 41 fixed to the outer wall of the housing 1. A motor 42 is fixed to the top of the bracket 41. A bevel gear 43 is fixed to the output shaft of the motor 42. A bevel gear 44 meshes below the bevel gear 43. A rotating shaft 45 is fixed to the bevel gear 44. The two ends of the rotating shaft 45 are rotatably connected to the bracket 41. A drive wheel 46 is fixed to the rotating shaft 45. A driven wheel 47 is fixed to the outer wall of the drying drum 21. A belt 48 is provided between the driving wheel 46 and the driven wheel 47, and the belt 48 passes through the outer wall of the machine casing 1. The starting of the motor 42 can drive the bevel gear 43 to rotate. When the bevel gear 43 rotates, it can drive the bevel gear 44 that meshes with it to rotate. The rotation of the bevel gear 44 can drive the rotating shaft 45 and the driving wheel 46 to rotate respectively. When the driving wheel 46 rotates, it can drive the belt 48 and the driven wheel 47 respectively. The rotation of the driven wheel 47 can drive the drying drum 21 to rotate on the three limit wheels 33.

[0022] The outer wall of the drying cylinder 21 has several air inlets. A heating mechanism 5 is installed inside the casing 1. The heating mechanism 5 includes a heating box 51, which is located on one side of the casing 1. An air inlet pipe 52 connects the heating box 51 to the casing 1. A first exhaust fan 53 is fixed to the bottom of the support plate 11, and an exhaust pipe 54 is connected to the first exhaust fan 53, passing through the top of the support plate 11. A second exhaust fan 55 is fixed to the top of the casing 1, and an exhaust pipe 56 is connected to the second exhaust fan 55. An exhaust slot 57 is opened at the top of the casing 1, and the exhaust pipe 56 is connected to the exhaust slot 57. A filter screen 58 is installed inside the air outlet 57; the steam inside the heating box 51 can be transported to the inside of the machine casing 1 through the air inlet pipe 52. With the cooperation of the exhaust fan 53 and the air outlet pipe 54, the steam inside the machine casing 1 can be evenly transported to the two drying chambers 2. Then, the steam can enter the drying drum 21 through several air inlets, so as to dry the fabric inside the drying drum 21. With the cooperation of the exhaust fan 55 and the exhaust pipe 56, the steam inside the drying chamber 2 can be discharged. The filter screen 58 can filter impurities in the steam.

[0023] A concave frame 6 is provided at one end of the housing 1. Several conveying rollers 61 are arranged inside the concave frame 6. A water-squeezing mechanism 7 is provided on the concave frame 6. The water-squeezing mechanism 7 includes a first water-squeezing roller 71 and a second water-squeezing roller 72. The second water-squeezing roller 72 is located below the first water-squeezing roller 71 and its two ends are rotatably connected to the inner wall of the concave frame 6. Sliding grooves 73 are opened on both sides of the inner wall of the concave frame 6. Sliding blocks 74 are slidably connected inside the two sliding grooves 73. The two ends of the first water-squeezing roller 71 are rotatably connected to the two sliding blocks 74. A mounting plate 75 and a bearing seat 76 are fixed at the top of the concave frame 6. A second motor 751 is fixed at the top of the mounting plate 75. A rotating rod 77 is arranged between the second motor 751 and the bearing seat 76. Two symmetrical worm gears 78 are fixed on the rotating rod 77. A worm wheel 79 is meshed on one side of each of the two worm gears 78. A threaded rod 791 is fixed on each of the two worm wheels 79. One end of each of the two threaded rods 791 passes through the top of the concave frame 6 and the bottom end is rotatably connected to the bottom of the inner side of the slide groove 73. The threaded rods 791 are threadedly connected to the sliders 74. When the fabric passes through several conveyor rollers 61 and reaches between the first squeezing roller 71 and the second squeezing roller 72, the start of the second motor 751 can drive the rotating rod 77 to rotate. When the rotating rod 77 rotates, it can drive the two worm gears 78 to rotate. The rotation of the two worm gears 78 can drive the two worm wheels 79 to rotate. When the two worm wheels 79 rotate, they can drive the two threaded rods 791 to rotate. The rotation of the two threaded rods 791 can drive the two sliders 74 to slide inside the two slide grooves 73. When the two sliders 74 slide, they can drive the first squeezing roller 71 to move up and down. By adjusting the distance between the first squeezing roller 71 and the second squeezing roller 72, it is convenient to perform water squeezing on the fabric.

[0024] Working principle: The operator can first pass the strip-shaped fabric through two drying cylinders 21 and several conveyor rollers 61 until it reaches the existing winding mechanism. When the existing winding mechanism starts to collect the fabric, the motor 42 of the drive mechanism 4 is started first, which drives the bevel gear 43 to rotate. When the bevel gear 43 rotates, it drives the bevel gear 44 that meshes with it to rotate. The rotation of the bevel gear 44 drives the rotating shaft 45 and the driving wheel 46 to rotate respectively. When the driving wheel 46 rotates, it drives the belt 48 and the driven wheel 47 respectively. The rotation of the driven wheel 47 drives the drying cylinder 21 to rotate on the three limit wheels 33. When the drying cylinder 21 rotates, it drives the fabric inside to rotate together. When the fabric collides with the inner wall of the drying cylinder 21, the water in the fabric can also be squeezed out.

[0025] Next, the heating chamber 51 of the heating mechanism 5 is started. The steam inside can be transported to the inside of the casing 1 through the air inlet pipe 52. With the cooperation of the exhaust fan 53 and the air outlet pipe 54, the steam inside the casing 1 can be evenly transported to the two drying chambers 2. Then, the steam can enter the drying cylinder 21 through several air inlets, so that the fabric inside the drying cylinder 21 can be dried.

[0026] When the fabric passes through a drying cylinder 21 and several conveyor rollers 61 in sequence and reaches between the first squeezing roller 71 and the second squeezing roller 72, the fabric has completed its initial drying. Then, by starting the motor 751 of the squeezing mechanism 7, the rotating rod 77 can be driven to rotate. When the rotating rod 77 rotates, it can drive the two worm gears 78 to rotate. The rotation of the two worm gears 78 can drive the two worm wheels 79 to rotate. When the two worm wheels 79 rotate, they can drive the two threaded rods 791 to rotate. The rotation of the two threaded rods 791 can drive the two sliders 74 to slide inside the two grooves 73. When the two sliders 74 slide, they can drive the first squeezing roller 71 to move up and down. By adjusting the distance between the first squeezing roller 71 and the second squeezing roller 72, it is convenient to squeeze water out of the fabric. After the fabric has been squeezed, it enters another drying cylinder 21. According to the heating mechanism 5 mentioned above, the fabric can be dried a second time, and finally, the effect of complete drying can be achieved.

[0027] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
