Description

Technical Field

[0001] This invention relates to the field of fabric equipment technology, and in particular to a fabric drum dryer. Background Technology

[0002] With the continuous development of society, my country's textile industry has also entered a period of rapid development. Textile fabrics have gradually become the main material for making clothing. In the production process of textile fabrics, the drying efficiency of drying equipment can directly affect the quality of textile fabrics, so the selection of drying equipment is very important.

[0003] Existing rotary drum dryers typically dry textile fabrics only once during operation. Using long drums to convey the fabric not only increases the contact area between the drum and the fabric but also reduces the contact area between the fabric and hot air, ultimately lowering the dryer's drying efficiency. To address these issues, a solution is proposed below. Summary of the Invention

[0004] The purpose of this invention is to provide a fabric drum dryer to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A fabric drum dryer includes a casing, inside which are three drying drums. Inside the casing are three support mechanisms for supporting the drying drums. Outside the casing are three drive mechanisms for rotating the drying drums. Inside the casing is a steam circulation mechanism. At the top of the casing is an exhaust mechanism. At both ends of the casing are a fabric opening machine body and a conveyor frame, respectively. At both ends of the outer wall of the casing are two feed inlets and two discharge outlets, each with an anti-knotting mechanism.

[0007] Preferably, a support plate is fixed inside the housing, and a partition plate 1 and a partition plate 2 are fixed on both sides of the support plate respectively. The support plate, partition plate 1 and partition plate 2 divide the inside of the housing into a heating chamber, a drying chamber 1, a drying chamber 2 and a drying chamber 3.

[0008] Preferably, the support mechanism includes two support frames 1 and two support frames 2 fixed to the top of the partition 1. Each of the two support frames 1 and support frames 2 is rotatably connected to a support wheel. The top of the inside of the housing is fixed with two support frames 3. Each of the two support frames 3 is rotatably connected to a limit wheel. The support frames 1, 2 and 3 are all concave in shape.

[0009] Preferably, the drive mechanism includes a concave frame fixed to the outer wall of the housing, a motor fixed to the top of the concave frame, a worm fixed to the output shaft of the motor, the bottom end of the worm being rotatably connected to the inside of the concave frame and meshing with a worm wheel on one side, a rotating shaft fixed to the worm wheel, a driving wheel fixed to the rotating shaft and both ends being rotatably connected to the inner wall of the concave frame, a driven wheel fixed to the outside of the drying cylinder, and a belt between the driving wheel and the driven wheel, the belt passing through the outer wall of the housing.

[0010] Preferably, the steam circulation mechanism includes an air inlet pipe that passes through the outer wall of the housing and is connected to a heater body. The heater body is located inside the heating chamber and is connected to an air outlet pipe on one side. One end of the air outlet pipe passes through a support plate and is located inside a drying chamber. A through groove is provided through the support plate, partition plate one, and partition plate two. A filter screen one and a fan one are respectively arranged inside the three through grooves one from bottom to top. A circulation pipe is connected between the top of the heater body and the through groove one.

[0011] Preferably, the exhaust mechanism includes an exhaust pipe that passes through the top of the casing and is connected to the drying chamber. A filter screen is installed inside the exhaust pipe. A discharge seat is fixed at the top of the casing. A discharge groove is opened at the top of the discharge seat. One end of the exhaust pipe passes through the discharge pipe and is connected to the discharge groove. A through groove is formed on one side of the outer wall of the discharge seat. A fan is installed inside the through groove.

[0012] Preferably, the conveyor frame is U-shaped and has several conveyor rollers rotatably connected inside.

[0013] Preferably, the anti-knotting mechanism includes an anti-knotting hopper, which is inclined and hinged to the inside of the feed inlet. Two symmetrical support blocks are provided below the anti-knotting hopper, and a cylinder is hinged between the two support blocks and fixed to the outer wall of the machine housing. The piston rod of the cylinder is hinged to the bottom end of the anti-knotting hopper.

[0014] Preferably, all three drying cylinders are inclined, and each of the three drying cylinders has a number of circumferentially arranged guide plates fixed inside.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. Through the cooperation of the drive mechanism, the opening machine body, the conveyor frame and the three inclined drying cylinders, the fabric can pass through the three drying cylinders in sequence. By starting the steam circulation mechanism, the fabric can be dried three times, so as to fully dry the fabric.

[0017] 2. By setting up several guide plates, not only can the tumbling of the fabric inside the drying drum be effectively improved, but the shrinkage rate of the fabric can also be controlled, which helps to dry the rope-like fabric in the early stage.

[0018] 3. By setting up the anti-knotting chute, the time it takes for the fabric to fall into the drying drum can be extended, and the situation that might have accumulated inside the drying drum can be changed to the chute, thereby preventing the fabric from knotting inside the drying drum. In addition, the position of the anti-knotting chute can be adjusted by the cylinder, so as to adapt to various fabrics required by different customers. Attached Figure Description

Detailed Implementation

[0027] The following description is merely a preferred embodiment of the present invention, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of the present invention should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0028] like Figures 1 to 7 As shown, a fabric drum dryer includes a housing 1, inside which three drying drums 11 are arranged. A support plate 12 is fixed inside the housing 1. A partition plate 13 and a partition plate 14 are fixed on both sides of the support plate 12, respectively. The support plate 12, the partition plate 13 and the partition plate 14 divide the interior of the housing 1 into a heating chamber 16, a first drying chamber 17, a second drying chamber 18 and a third drying chamber 19. The three drying drums 11 are located inside the first drying chamber 17, the second drying chamber 18 and the third drying chamber 19, respectively. Three support mechanisms 2 are provided inside the housing 1, each of which can support the drying drums 11.

[0029] The support mechanism 2 includes two support frames 21 and two support frames 22 fixed to the top of the partition 13. Support wheels 24 are rotatably connected inside the two support frames 21 and the two support frames 22. Two support frames 23 are fixed to the top of the inside of the housing 1. Limiting wheels 25 are rotatably connected to the two support frames 23. The support frames 21, 22 and 3 are all concave. Through the cooperation of multiple support wheels 24 and two limiting wheels 25, it can not only support the drying cylinder 11, but also prevent the drying cylinder 11 from derailing when rotating.

[0030] The outer casing 1 is equipped with three drive mechanisms 3, each used to drive the drying drum 11 to rotate. Each drive mechanism 3 includes a concave frame 31 fixed to the outer wall of the casing 1. A motor 32 is fixed to the top of the concave frame 31. A worm gear 33 is fixed to the output shaft of the motor 32. The bottom end of the worm gear 33 is rotatably connected to the inside of the concave frame 31 and meshes with a worm wheel 34 on one side. A rotating shaft 35 is fixed to the worm wheel 34. A drive wheel 36 is fixed to the rotating shaft 35 and both ends are rotatably connected to the inner wall of the concave frame 31. Next, a driven wheel 37 is fixedly installed outside the drying cylinder 11, and a belt 38 is provided between the driving wheel 36 and the driven wheel 37. The belt 38 passes through the outer wall of the machine casing 1. When the motor 32 is started, it can first drive the worm gear 33 to rotate. When the worm gear 33 rotates, it can drive the worm wheel 34, the rotating shaft 35 and the driving wheel 36 to rotate respectively. The rotation of the driving wheel 36 can drive the belt 38 and the driven wheel 37 to rotate respectively. When the driven wheel 37 rotates, it can drive the drying cylinder 11 to rotate.

[0031] All three drying cylinders 11 are inclined, and each of the three drying cylinders 11 has several circumferentially arranged guide plates 111 fixed inside. Because the three drying cylinders 11 are inclined, the fabric can be conveyed more easily when the drying cylinders 11 rotate. The arrangement of several guide plates 111 can not only effectively improve the tumbling of the fabric inside the drying cylinders 11, but also control the shrinkage rate of the fabric, thus helping to dry the rope-like fabric in the early stage.

[0032] A steam circulation mechanism 4 is installed inside the casing 1. The steam circulation mechanism 4 includes an air inlet pipe 41, which passes through the outer wall of the casing 1 and is connected to a heater body 42. The heater body 42 is an existing heater, located inside the heating chamber 16, and is connected to an air outlet pipe 43 on one side. One end of the air outlet pipe 43 passes through a support plate 12 and is located inside the drying chamber 17. A through groove 44 is passed through the support plate 12, the partition 13, and the partition 2 14. A filter screen 45 and a fan 46 are respectively installed inside the three through grooves 44 from bottom to top. A circulation pipe 47 connects the top of the heater body 42 to the through groove 44. External steam can enter the heater body 42 through the inlet pipe 41, and then enter the drying chamber 17 through the outlet pipe 43. By starting multiple fans 46, the steam can enter the drying chamber 2 18 and the drying chamber 3 19 respectively. The multiple filters 45 not only filter the steam, but also prevent impurities such as lint from entering the drying chamber 2 18 or the drying chamber 3 19. The dried gas can enter the heater body 42 through the circulation pipe 47. By starting the heater body 42, the gas can be reheated and reused, thus achieving a circulation effect.

[0033] An exhaust mechanism 5 is provided at the top of the casing 1. The exhaust mechanism 5 includes an exhaust pipe 51, which passes through the top of the casing 1 and is connected to the drying chamber 19. A filter screen 52 is installed inside the exhaust pipe 51. A discharge seat 53 is fixed at the top of the casing 1. A discharge groove is opened at the top of the discharge seat 53. One end of the exhaust pipe 51 passes through the discharge pipe and is connected to the discharge groove. A through groove 2 runs through one side of the outer wall of the discharge seat 53. A fan 54 is installed inside the through groove 2. By starting the fan 54, water vapor and exhaust gas inside the drying chamber 19 can pass through the exhaust pipe 51 and the discharge seat 53 in sequence until they are discharged from the discharge groove. The filter screen 52 can effectively clean and filter impurities such as cotton fibers.

[0034] The machine casing 1 has a fabric spreading machine body 15 and a conveyor frame 151 at both ends. The fabric spreading machine body 15 is an existing fabric spreading machine. The conveyor frame 151 is U-shaped and has several conveyor rollers 152 rotatably connected inside. The outer wall of the machine casing 1 has two feed ports 71 and two discharge ports 7 at both ends. When the strip fabric passes through the two feed ports 71 and the two discharge ports 7 and enters the three drying cylinders 11 in sequence, the start of the fabric spreading machine body 15 can not only perform the spreading operation on the strip fabric, but also facilitate the transport of the spread fabric to the next drying cylinder 11. Through the cooperation of the conveyor frame 151 and several conveyor rollers 152, the fabric in the second drying cylinder 11 can be transported to the third drying cylinder 11, so that the fabric can be dried multiple times.

[0035] Both feed inlets 71 are equipped with anti-knotting mechanisms 6. The anti-knotting mechanism 6 includes an anti-knotting chute 61, which is inclined and hinged to the inside of the feed inlet 71. Two symmetrical support blocks 62 are provided below the anti-knotting chute 61. A cylinder 63 is hinged between the two support blocks 62 and fixed to the outer wall of the machine housing 1. The piston rod of the cylinder 63 is hinged to the bottom end of the anti-knotting chute 61. By setting the anti-knotting chute 61, the time for the fabric to fall into the drying drum 11 can be extended, and the situation that may have accumulated in the drying drum 11 can be changed to the chute, thereby preventing the fabric from knotting inside the drying drum 11. In addition, by activating the cylinder 63, the anti-knotting chute 61 can be moved up and down around the hinge point of the feed inlet 71, thereby accommodating fabrics of various specifications.

[0036] Working principle: When the operator pulls the strip fabric into the two feed ports 71, two discharge ports 7, and three drying cylinders 11 in sequence, the motor 32 of the drive mechanism 3 is started, which drives the worm gear 33 to rotate. When the worm gear 33 rotates, it drives the worm wheel 34, the rotating shaft 35, and the driving wheel 36 to rotate. The rotation of the driving wheel 36 drives the belt 38 and the driven wheel 37 to rotate. When the driven wheel 37 rotates, it drives the drying cylinders 11 to rotate. The rotation of the three inclined drying cylinders 11 facilitates the conveying of the fabric. The opening machine body 15 not only allows for the opening of the strip fabric but also facilitates the transport of the opened fabric to the next drying cylinder 11. Through the cooperation of the conveyor frame 151 and several conveyor rollers 152, the fabric inside the second drying cylinder 11 can be easily transported to the third drying cylinder 11.

[0037] During fabric transportation, external steam can enter the heater body 42 through the air inlet pipe 41, and then enter the drying chamber 17 through the air outlet pipe 43. By starting multiple fans 46, steam can enter the drying chambers 18 and 19 respectively, thus drying the fabric inside the three drying cylinders 11. Through multiple drying cycles, the fabric can be thoroughly dried. After drying, the gas can enter the heater body 42 through the circulation pipe 47. By starting the heater body 42, the gas can be reheated and reused, thus achieving a circulation effect.
