Description

Technical Field

[0001] The present invention relates to the technical field of drying machines, and specifically to an automatic width adjustment device for the oven of a cylinder drying machine. Background Art

[0002] The cylinder drying machine is one of the main equipment in the non-woven fabric production process. This equipment uses the principle of hot air penetration, wraps the fabric on the surface of the cylinder, and the hot air blows towards the fabric and penetrates the fabric into the cylinder. In the existing cylinder drying machine ovens, generally, the humid and hot air is directly discharged, and the heat cannot be recycled, resulting in waste of heat. There are also devices that can recycle heat, but when recycling heat, only the inner cavity of the oven can be recycled as a whole, which is not particularly uniform.

[0003] For this reason, the patent with the publication number CN207395326U discloses a heat recycling device for the oven of a cylinder drying machine, which includes a dehumidifier. The dehumidifier is fixedly installed on the top plate of the oven. The dehumidifier is connected to the inner cavity of the oven through an air inlet pipe, and the air outlet end of the dehumidifier is connected to the air inlet end of a blower through a pipe.

[0004] For the above-mentioned heat recycling device for the oven of a cylinder drying machine, its drying quality is good, but there are still the following deficiencies: the width of the oven is fixed and cannot be flexibly adjusted according to the width of the fabric. When the width of the fabric is large, the fabric cannot be evenly distributed on the surface of the oven, resulting in poor drying effect.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an automatic width adjustment device for the oven of a cylinder drying machine is provided, in order to achieve a more practical and valuable purpose. Summary of the Invention

[0006] The purpose of the present invention is to provide an automatic width adjustment device for the oven of a cylinder drying machine to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solution: An automatic width adjustment device for the oven of a cylinder drying machine includes an oven body. Feeding ports and discharging ports are respectively arranged on the left and right sides of the oven body. The feeding ports and the discharging ports have the same size, and the size is set relatively large to facilitate wrapping the fabric on the surface of the roller. Second sliding rails and first sliding rails are respectively arranged on the upper and lower inner walls of the oven body. The first sliding rails are fixedly connected to the oven body. Two groups of electric cylinders are installed on the side of the oven body, and the piston rods of the electric cylinders are fixedly connected to the second sliding rails. The electric cylinders support the second sliding rails to achieve the purpose of moving the second sliding rails in the oven body;

[0008] Three sets of sliders are slidably connected to the surfaces of the first slide rail and the second slide rail, and the sliders on the upper and lower sides are respectively movably connected to a second rotating rod and a first rotating rod. A bearing seat is fixedly connected to the surface of the slider, and the first rotating rod and the second rotating rod are movably connected to the corresponding bearing seats. All three second rotating rods are connected to the upper sliders, and all three first rotating rods are connected to the lower sliders;

[0009] A roller is fixedly connected to the surface of the first rotating rod through a plurality of sets of elastic support mechanisms. Eight sets of elastic support mechanisms are provided and are arranged in a circular shape between the roller and the first rotating rod. The elastic support mechanism includes a sleeve, a plug rod, a universal ball, and a spring. The spring is arranged inside the sleeve, the plug rod is inserted into the sleeve, and the mutually remote ends of the sleeve and the plug rod are movably connected to the roller and the first rotating rod through two universal balls. The plug rod can slide in the sleeve, and the plug rod abuts against one end of the spring;

[0010] A disc is provided on the lower end surface of the second rotating rod. A rotating block is rotatably connected to the center of the disc surface. A plurality of fixing frames are provided on the edge of the disc surface. Five fixing frames are provided and the five fixing frames are arranged in a circular shape around the rotating block. A moving block is slidably connected to the inner wall of the fixing frame through a smooth rod. A tension spring is sleeved on the smooth rod, and both ends of the tension spring are fixedly connected to the fixing frame and the moving block respectively. A support plate is provided on the lower end surface of the moving block. An insertion plate is provided on the lower end surface of the support plate and is inserted into the corresponding roller. The moving block and the rotating block are movably connected through a pull rod. One end of the pull rod close to the moving block is movably connected to a first pin shaft seat, and the first pin shaft seat is fixedly connected to the moving block. One end of the pull rod close to the rotating block is movably connected to a second pin shaft seat, and the second pin shaft seat is fixedly connected to the rotating block.

[0011] Further, the support plate is arc-shaped, and there is a gap between adjacent support plates, which is beneficial for the support plates to approach each other, so that the support plates can be smoothly inserted into the roller. The surface of the insertion plate is inclined, and the inclined surface of the insertion plate abuts against the inner wall of the roller.

[0012] Further, two motors are installed on the lower surface of the oven body. The output end of the motor penetrates through the oven body and is fixedly connected to a first transmission bar. A second transmission bar is rotatably connected to the surface of the first transmission bar, and the second transmission bar is rotatably connected to the corresponding slider. The motor adopts a servo motor, and the rotation speed and rotation angle of the motor can be controlled.

[0013] Further, a locking screw is screwed in the middle of the upper surface of the oven body, and the threaded end of the locking screw abuts against the surface of the corresponding slider. The non-threaded end of the locking screw has a larger size, which is convenient for manually screwing the locking screw without using a wrench.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention can control the movement of the second slide rail through an electric cylinder. The second slide rail pushes the support plate into the corresponding roller, thereby adjusting the combined length of the roller and the support plate, facilitating adaptation to fabrics of different widths, enabling the fabric to fit on the surfaces of the roller and the support plate, providing good support for the fabric, preventing fabric stacking, and achieving better drying effect for the fabric. By using a motor, the movement of the left and right groups of rollers can be controlled to adjust the distance between the rollers, avoiding interference between adjacent rollers and facilitating covering fabrics of different thicknesses on the rollers, thus improving the drying efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5, the present invention provides a technical solution: an automatic width adjustment device for the oven of a cylinder dryer, including an oven body 1. Feed ports 3 and discharge ports 2 are respectively provided on the left and right side surfaces of the oven body 1. Second slide rails 5 and first slide rails 4 are respectively provided on the upper and lower inner walls of the oven body 1. Two sets of electric cylinders 26 are installed on the side surface of the oven body 1, and the piston rods of the electric cylinders 26 are fixedly connected to the second slide rails 5. The oven body 1 supports the electric cylinders 26 and the first slide rails 4, and the electric cylinders 26 are used to control the movement of the second slide rails 5;

[0023] Three sets of sliders 6 are slidably connected to the surfaces of the first slide rails 4 and the second slide rails 5. The sliders 6 on the upper and lower sides are respectively movably connected to a second rotating rod 14 and a first rotating rod 8. The first slide rails 4 and the second slide rails also support the corresponding sliders 6 to prevent the sliders 6 from shaking, so that the sliders 6 can only slide along the first slide rails 4 and the second slide rails 5;

[0024] A drum 13 is fixedly connected to the surface of the first rotating rod 8 through a plurality of sets of elastic support mechanisms. The elastic support mechanisms fixedly connect the drum 13 and the first rotating rod 8. A disc 15 is provided on the lower end surface of the second rotating rod 14. A rotating block 16 is rotatably connected to the center of the surface of the disc 15. A plurality of sets of fixed frames 17 are provided on the edge of the surface of the disc 15. A moving block 20 is slidably connected to the inner wall of the fixed frame 17 through a smooth rod 18. A tension spring 19 is sleeved on the surface of the smooth rod 18, and both ends of the tension spring 19 are fixedly connected to the fixed frame 17 and the moving block 20 respectively. A support plate 21 is provided on the lower end surface of the moving block 20. An insertion plate 25 is provided on the lower end surface of the support plate 21, and the insertion plate 25 is inserted into the corresponding drum 13. The moving block 20 and the rotating block 16 are movably connected through a pull rod 23. The pull rod 23 can be used to control the simultaneous movement of a plurality of sets of support plates 21.

[0025] Specifically, when implemented, eight sets of elastic support mechanisms are provided and arranged in a circular shape between the drum 13 and the first rotating rod 8 to improve the connection stability between the drum 13 and the first rotating rod 8.

[0026] Specifically, when implemented, the elastic support mechanism includes a sleeve 10, an insertion rod 12, a universal ball 9, and a spring 11. The spring 11 is arranged inside the sleeve 10. The insertion rod 12 is inserted into the sleeve 10. The mutually remote ends of the sleeve 10 and the insertion rod 12 are movably connected to the drum 13 and the first rotating rod 8 through two sets of universal balls 9. Under the action of the universal balls 9, the drum 13 can slightly move on the surface of the first rotating rod 8. The support of the spring 11 supports the sleeve 10 and the insertion rod 12 to prevent the drum 13 from shaking.

[0027] During specific implementation, one end of the pull rod 23 close to the moving block 20 is movably connected to a first pin shaft seat 22, and the first pin shaft seat 22 is fixedly connected to the moving block 20. One end of the pull rod 23 close to the rotating block 16 is movably connected to a second pin shaft seat 24, and the second pin shaft seat 24 is fixedly connected to the rotating block 16, realizing the movable connection between the rotating block 16 and the moving block 20.

[0028] During specific implementation, five groups of fixed frames 17 are provided, and the five groups of fixed frames 17 are arranged in a circle around the rotating block 16. The five groups of fixed frames 17 arranged in a circle make the five groups of support plates 21 also arranged in a circle, which is beneficial to the fabric being wrapped around the surface of the support plates 21.

[0029] During specific implementation, the support plate 21 is arranged in an arc shape, which is beneficial to the support plate 21 being inserted into the inside of the drum 13. The surface of the insertion plate 25 is inclined, so that the insertion plate 25 can be smoothly inserted into the inside of the drum 13.

[0030] During specific implementation, two motors 27 are installed on the lower surface of the oven body 1. The output end of the motor 27 penetrates through the oven body 1 and is fixedly connected to a first transmission bar 28. A second transmission bar 29 is rotatably connected to the surface of the first transmission bar 28, and the second transmission bar 29 is rotatably connected to the corresponding slider 6, so that the motor 27 can control the corresponding slider 6 to slide.

[0031] During specific implementation, a bearing seat 7 is fixedly connected to the surface of the slider 6. The first rotating rod 8 and the second rotating rod 14 are movably connected to the corresponding bearing seats 7. The bearing seats 7 fix the first rotating rod 8 and the second rotating rod 14 and enable the first rotating rod 8 and the second rotating rod 14 to rotate smoothly.

[0032] During specific implementation, a locking screw rod 30 is screwed in the middle of the upper surface of the oven body 1, and the threaded end of the locking screw rod 30 abuts against the surface of the corresponding slider 6. The locking screw rod 30 can prevent the corresponding slider 6 from sliding, thereby restricting the movement of the corresponding drum 13.

[0033] Specifically, during use, adjust the combined length of the roller 13 and the support plate 21 according to the width of the fabric. Start the two sets of electric cylinders 26. The electric cylinders 26 push the second slide rail 5 to move. The second slide rail 5 drives the second rotating rod 14 to move through the corresponding three sets of sliders 6. The second rotating rod 14 drives the disc 15 to move. The disc 15 drives the five sets of support plates 21 to move into the roller 13 through the fixed frame 17 and the moving block 20. Restricted by the roller 13, the support plate 21 drives the moving block 20 to slide along the corresponding optical rod 18. The moving block 20 also drives the rotating block 16 to rotate through the corresponding first pin seat 22, the pull rod 23, and the second pin seat 24. Since the five sets of support plates 21 are all movably connected to the rotating block 16, the five sets of support plates 21 move synchronously. Under the pulling force of the tension spring 19, the support plate 21 adheres to the inner wall of the roller 13. The longer the piston rod of the electric cylinder 26 extends, the shorter the combined length of the roller 13 and the support plate 21, which can be freely adjusted according to the width of the fabric. Then, insert the fabric into the oven body 1 from the feed port 3 and connect it to the middle roller 13. Rotating the roller 13 can wrap the fabric around the surfaces of the roller 13 and the support plate 21. Then, wrap the fabric from the feed port 3 and the discharge port 2 around the roller 13 and the support plate 21 on the left and right sides. Start the motor 27. The motor 27 drives the first transmission strip 28 to rotate. The first transmission strip 28 drives the second transmission strip 29 to rotate. The second transmission strip 29 pulls the slider 6 to slide. The slider 6 drives the first rotating rod 8 and the roller 13 to move. Since the support plate 21 is inserted into the roller 13, the roller 13 can drive the support plate 21 to move, thereby adjusting the distance between adjacent rollers 13. Pass hot air into the oven body 1 through the feed port 3 and the discharge port 2 to dry the fabric.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
