Description

Technical Field

[0001] The invention relates to the field of textile printing and dyeing machinery, and in particular to a continuous drum drying device. Background Art

[0002] The drum dryer is a common machine used in the textile and printing and dyeing industry to improve the texture of fabrics and dry them. It is usually used in the finishing process of fabrics. After the fabrics are washed, they are processed in a drum dryer, which can effectively improve the texture of the fabrics and improve the quality of the fabrics.

[0003] The working mode of the existing drum dryer is generally to feed the cloth at one end and discharge the cloth at the other end. The number of cloth inlets can be adjusted according to the needs of the user, and can be three or four. The cloth inside is beaten by continuously rotating the internal drum forward and backward. For drying, holes are opened on the internal drum, and the cloth inside the drum is dried by circulating hot air. However, the existing drying method causes the wind that contacts the cloth to be in a vertical direction, and the cloth is easy to stick inside the drum. In addition, the drying efficiency is very low, and some cloth is not easy to be dried. Summary of the invention

[0035] The invention comprises an oven 11, a feed port 15 and a discharge port 12 are respectively arranged on both sides of the oven 11, a feeding assembly is arranged on one side of the feed port 15, and the feeding assembly comprises a conveying frame 18, a feeding roller 17 is rotatably mounted on the conveying frame 18, the feeding roller 17 is fixed to the motor shaft of a first motor 16, the first motor 16 is fixedly mounted on the conveying frame 18, and the first motor 16 drives the feeding roller 17 to rotate after starting, so as to convey the cloth on the feeding roller 17 into the feed port 15 and finally output it from the discharge port 12;

[0036] A roller 20 is rotatably mounted in the oven 11. The roller 20 is rotatably mounted between at least two limiting structures 60 fixed to the oven 11. The limiting structure 60 includes a rotating frame 30 fixed to the oven 11. At least three fixing plates 29 are fixedly mounted on the rotating frame 30. Limiting wheels 31 are rotatably mounted on the fixing plates 29. The limiting wheels 31 are partially embedded in limiting rails 32 fixed to the roller 20. Each limiting wheel 31 limits the limiting rails 32, thereby ensuring the stability of the roller 20 during rotation.

[0037] The drum 20 is driven by a pulley mechanism in the oven 11, and the pulley mechanism includes a second motor 23 fixed to the oven 11, a first pulley 24 is fixed on the motor shaft of the second motor 23, the first pulley 24 and the second pulley 21 are driven by a belt 22, the second pulley 21 is fixed on the drum 20, and the second motor 23 drives the first pulley 24 to rotate after starting, and the second pulley 21 rotates through the transmission of the belt 22, and the second pulley 21 drives the drum 20 to rotate;

[0038] At least one beating knife 25 is fixedly installed in the drum 20, and the beating knife 25 rotates with the drum 20 to beat the cloth inside. The drum 20 is tilted to ensure automatic transportation of the cloth;

[0039] Heating holes 33 are evenly provided on the drum 20, and at least one hot air circulation component 80 is installed on the oven 11. The hot air circulation component 80 is used to provide circulating hot air, and the hot air dries the cloth in the drum 20 through the heating holes 33. The hot air circulation component 80 includes an air outlet component 14 fixed on the top of the oven 11 and an air inlet component 42 fixedly installed in the oven 11. The air inlet component 42 is fixedly connected with the air outlet component 14 through an air duct 19. A third motor 13 is fixedly installed on one side of the air inlet component 42. After the third motor 13 is started, the air is input into the air duct 19 through the air inlet component 42 and finally discharged from the air outlet component 14. An electric heating structure is installed in the air outlet component 14 to realize the supply of hot air.

[0040] In the above structure, the hot air dries the cloth only through each of the heating holes 33, the drying position is single, and the drying efficiency is low;

[0041] In order to solve the above problems, the applicant has made a series of improvements to the flapping knife 25, specifically:

[0042] The beating knife 25 is made into a plate-like U-shaped structure, and the beating knife 25 is concavely arranged on the drum 20. The beating knife 25 is composed of two side plates and a top plate. Air inlet slots 26 are evenly opened on the side plates. The air inlet slots 26 increase the contact range between the hot air and the cloth in the drum 20, so that the cloth in the drum 20 can be better dried.

[0043] However, the above structure is the same as the heating hole 33, which only provides hot air heating in the vertical direction. The applicant hopes to provide hot air heating in other directions. Based on this, an air guide plate 45 arranged on the inner wall of the drum 20 is installed at the bottom of the air inlet groove 26. The air guide plate 45 is grooved, and the direction of the groove is parallel to the inner wall of the drum 20. The advantage of this design is that after the hot air enters the air inlet groove 26, it will be guided by the air guide plate 45, so as to flow along the inner wall of the drum 20, horizontally dry the cloth on the inner wall of the drum 20, and have a certain driving effect.

[0044] When dealing with fuzzy or highly sticky cloth, the cloth is easily stacked and adhered to the beating knife 25. To improve this situation, the air guide plate 45 is further improved, specifically including:

[0045] A base 46 fixed to the drum 20 is provided on one side of each of the air guide plates 45, one side of the air guide plate 45 is hingedly provided on the base 46, a torsion spring is installed between the air guide plate 45 and the base 46, and a connecting plate 27 is fixedly installed on the air guide plate 45; an anti-adhesion mechanism 70 is installed on the drum 20, and the anti-adhesion mechanism 70 includes an outer frame 34 sleeved on the drum 20, a guide rail 38 is rotatably installed in the outer frame 34, and a movable plate 39 with the same number as the flapping knife 25 is fixed on the inner side of the guide rail 38, and the end of the movable plate 39 is slidably provided in the slide rail 41, and the slide rail 41 is fixedly installed on the outer side of the flapping knife 25, and is symmetrical on the movable plate 39 A push plate 40 is fixed, and the push plate 40 is arc-shaped. A moving assembly that drives the guide rail 38 to move along the drum 20 is installed between the rotating frame 30. The guide rail 38 is driven to move by the moving assembly, and the push plate 40 is driven to move along the beating knife 25. The push plate 40 will push the connecting plate 27 to rotate during the movement, and the connecting plate 27 will drive the air guide plate 45 to rotate. When the air guide plate 45 rotates, the cloth in the drum 20 will be lifted up, so that the cloth is not easy to stack and stick, thereby ensuring the stable quality of the produced cloth. When the air guide plate 45 rotates, the hot air guided by the air guide plate 45 will also change direction, which can apply force to the cloth and prevent stacking and sticking.

[0046] The guide rail 38 is guided by at least three guide wheels 37 embedded in the guide rail 38 , and the guide wheels 37 are rotatably disposed on a fixed head 36 , and the fixed head 36 is fixed to the outer frame 34 ;

[0047] The moving assembly includes a threaded rod 43 penetrating one side of the outer frame 34 and a guide rod 28 penetrating the other side. The guide rod 28 is fixed between the two rotating frames 30 to guide the outer frame 34. The threaded rod 43 is rotatably arranged between the two rotating frames 30. The threaded rod 43 is threadedly connected to the outer frame 34. A gear 35 is fixed on the threaded rod 43. The gear 35 meshes with a gear ring 47. The gear ring 47 is fixed on the roller 20. The gear ring 47 rotates with the roller 20. The gear 35 is driven to rotate by the meshing of the gear ring 47 and the gear 35, thereby driving the threaded rod 43 to rotate. The outer frame 34 is driven to move by the rotation of the threaded rod 43, thereby driving the guide rail 38 on the outer frame 34 to move.

[0048] Furthermore, a soft film 44 is fixedly provided between the air guide plate 45 and the inner wall of the drum 20. Due to the existence of the soft film 44, when the air guide plate 45 rotates, hot air will not flow away from the side of the air guide plate 45, thereby improving the drying efficiency.

[0049] Of course, the present application is mainly an improvement on the drum 20. When the drum 20 in the present application is applied to a three-drum or four-drum dryer, it should also fall within the scope of protection of the present application, because it is only a certain improvement in the internal transmission structure and the fabric conveying structure, which does not exceed the cognitive scope of those skilled in the art and is something that those skilled in the art can easily think of.

[0050] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology in this field to understand the content of the present invention and implement it, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
