Description

Technical Field

[0001] This utility model relates to the field of anti-bending and cracking technology of chemical fiber paper tubes, and in particular to an anti-bending and cracking device for chemical fiber paper tubes. Background Technology

[0002] Chemical fiber paper tubes are tubular containers made primarily of paper used for winding chemical fiber products. They are typically made from multiple layers of paper rolled using a special process, usually undergoing coating and drying to enhance their strength and rigidity, enabling them to withstand the tension and weight during fiber winding. They possess good wear resistance and stability, ensuring that chemical fiber products are neatly wound and less prone to deformation or loosening during production, transportation, and storage. Furthermore, chemical fiber paper tubes are lightweight, facilitating handling and use, reducing labor intensity and transportation costs. They also exhibit a certain degree of corrosion resistance, allowing them to withstand some chemical substances in the chemical fiber production environment. Relatively environmentally friendly, they are recyclable and reusable, meeting the requirements of modern green industrial production, and are a commonly used auxiliary packaging material in the chemical fiber industry.

[0003] Chemical fiber paper tubes are mainly used in chemical fiber winding and spinning processes. The quality of the chemical fiber paper tubes directly affects these processes. During production, long paper tubes need to be cut into smaller sections, which then require end-face chamfering. In existing technology, long chemical fiber paper tubes are directly placed in an oven for drying, allowing the glue inside to dry and solidify quickly before cutting and chamfering. Due to the high-temperature solidification of the glue in the paper tubes, the cutting and chamfering processes can easily cause cracking and deformation. Large cracks can be identified visually and discarded, while small cracks and deformations are often difficult to detect and used as qualified products. However, these defects can easily lead to yarn breakage during spinning. On the other hand, cutting and chamfering without drying the glue can cause the glue to overflow, affecting the product quality and leading to cracking later on.

[0004] However, the support and positioning structures of existing anti-bending and cracking devices for chemical fiber paper tubes are mostly fixed and difficult to adjust flexibly. When faced with chemical fiber paper tubes of different inner diameters, they cannot be adapted to the specific dimensions of the paper tube's inner diameter. For example, for chemical fiber paper tubes with smaller inner diameters, the existing support components are too large and cannot accurately penetrate into the paper tube for effective support, causing the paper tube to wobble and shift during the cutting process, making it unable to stably withstand external forces. On the other hand, for chemical fiber paper tubes with larger inner diameters, the positioning structure of the device is not sized to fit tightly against the inner wall of the paper tube, making it impossible to accurately position the paper tube. This causes displacement during the cutting process, seriously affecting the accuracy and reliability of cutting chemical fiber paper tubes with different inner diameters. Therefore, to address these shortcomings, an anti-bending and cracking device for chemical fiber paper tubes is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a fiber paper tube anti-bending and cracking device, which aims to improve the problem that some existing fiber paper tube anti-bending and cracking devices cannot effectively support and position fiber paper tubes with different inner diameters.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a chemical fiber paper tube anti-bending and cracking device, comprising a base plate, a fixing mechanism provided on the top of the base plate, a top frame fixedly connected to the top of the base plate, a drying mechanism provided at the bottom of the top frame, and a bearing plate fixedly connected to the top of the base plate.

[0007] The fixing mechanism includes an adjusting assembly. Two driving assemblies are slidably connected to the top of the adjusting assembly. A movable disk is fixedly connected to one adjacent side of each of the two driving assemblies. Multiple fixing blocks are fixedly connected to one adjacent side of each of the two movable disks. A fixing shaft is fixedly connected inside each of the multiple fixing blocks. A rotating rod is rotatably connected to the outside of each of the multiple fixing shafts. A second fixing shaft is rotatably connected inside each of the multiple rotating rods. A second fixing block is fixedly connected to the outside of each of the multiple second fixing shafts. A sliding rod is fixedly connected to the inside of each of the multiple second fixing blocks. A fixing plate is fixedly connected to the top of each of the two adjusting assemblies. A support ring is fixedly connected to one adjacent side of each of the multiple second fixing blocks.

[0008] Through the above technical solution: the drive component drives the moving disk to move, the fixed block one on the moving disk is connected to the rotating rod through the fixed shaft one, the rotating rod is connected to the fixed block two through the fixed shaft two, and the slide rod in the fixed block two can slide in the slide groove of the fixed plate, so that the support ring can achieve the fixed operation of the chemical fiber paper tube.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a slide rail, the bottom of which is fixedly connected to the top of the base plate. Two sliders are slidably connected to the top of the slide rail, and a support plate is fixedly connected to the top of each slider. Multiple grooves are formed inside the two fixed plates.

[0011] Through the above technical solution: the two sliders on the slide rail can slide, the sliders drive the top support plate to move, and the multiple grooves opened in the fixed plate provide sliding space for the slide rod, thereby realizing the adjustment of the position of the fixed mechanism.

[0012] As a further description of the above technical solution:

[0013] Both drive components include mounting plates, the bottoms of the two mounting plates are fixedly connected to the tops of the two support plates, cylinders are mounted on the opposite sides of the two mounting plates, push rods are fixedly connected to the drive ends of the two cylinders, and the adjacent sides of the two push rods are fixedly connected to the opposite sides of the two moving disks.

[0014] The above technical solution involves a cylinder driving a moving disc via a push rod, causing the moving disc to move towards or away from each other, thereby clamping or releasing the chemical fiber paper tube.

[0015] As a further description of the above technical solution:

[0016] The drying mechanism includes a power component, an external threaded sleeve connected to the power component, a sliding block fixedly connected to the bottom of the threaded sleeve, a drying frame fixedly connected to the bottom of the sliding block, two limiting frames fixedly connected to the top of the drying frame, two fans fixedly connected inside the drying frame, two electric heating grids fixedly connected inside the drying frame, a drying lamp fixedly connected to the top inside the drying frame, two limiting grooves and a sliding groove formed on the top inside the top frame.

[0017] Through the above technical solution: the power component drives the threaded sleeve to move, the sliding block at the bottom of the threaded sleeve slides in the sliding groove, driving the drying frame to move. The fan, electric heating grid and drying lamp in the drying frame work together to dry the chemical fiber paper tube. The limiting frame slides in the limiting groove to ensure the stability of the drying frame movement.

[0018] As a further description of the above technical solution:

[0019] The power assembly includes a positioning plate, the bottom of which is fixedly connected to the top right side of the top frame. A motor is mounted on the left side of the positioning plate, a support plate is fixedly connected to the top left side of the top frame, and a threaded rod is fixedly connected to the output end of the motor.

[0020] The above technical solution involves a motor driving the threaded rod to rotate, with a support plate providing support and a base for rotation, thus enabling power output.

[0021] As a further description of the above technical solution:

[0022] The internal thread of the threaded sleeve is connected to the outside of the threaded rod, and the external sliding block is slidably connected to the inside of the sliding groove.

[0023] With the above technical solution: when the threaded rod rotates, the threaded sleeve will move along the threaded rod, and at the same time the sliding block will slide in the sliding groove, driving the drying frame to move.

[0024] As a further description of the above technical solution:

[0025] The external sliding connection of the limiting frame is inside the limiting groove, and the left side of the threaded rod is rotatably connected inside the support plate.

[0026] The above technical solution allows the limiting frame to slide within the limiting groove, ensuring the smooth movement of the drying frame. The left side of the threaded rod rotates within the support plate, making the rotation of the threaded rod more stable and providing reliable power for the movement of the drying frame.

[0027] As a further description of the above technical solution:

[0028] The slide bar is externally slidably connected to the inside of the slide groove, and the second fixing block is externally slidably connected to the inside of the fixing plate.

[0029] Through the above technical solution: the slide bar slides in the slide groove, and the second fixed block slides in the fixed plate. When the drive component drives the moving disk to move, this sliding cooperation enables the support ring to stably fix and loosen the chemical fiber paper tube.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, the cylinder drives the movable disk to move through the push rod. Multiple fixed blocks on the movable disk move synchronously, causing the rotating rod to rotate around the fixed shaft, which in turn drives the fixed shaft and fixed blocks to move. The sliding rod fixedly connected inside the fixed block slides in the sliding groove inside the fixed plate, ultimately causing the support rings fixedly connected to the near side of the multiple fixed blocks to expand or contract outward. By adjusting the position of the slider on the slide rail and controlling the extension and retraction of the cylinder, the degree of expansion of the support rings can be changed, thereby adapting to chemical fiber paper tubes with different inner diameters and realizing the support and positioning of chemical fiber paper tubes of different sizes.

[0032] 2. In this utility model, the threaded rod connected to the output end of the motor rotates, and through the threaded engagement with the threaded sleeve, it drives the threaded sleeve to move. The sliding block fixedly connected to the bottom of the threaded sleeve slides in the sliding groove opened on the top side inside the top frame, thereby driving the drying frame to move. The limiting frame fixedly connected to the top of the drying frame slides in the limiting groove opened on the top side inside the top frame, ensuring the accuracy of the movement of the drying frame. The fan inside the drying frame draws in outside air, which is heated by the electric heating grid to form hot air. At the same time, the drying lamp on the top side inside the drying frame emits infrared rays. The two work together to act on the chemical fiber paper tube. By starting the motor and adjusting the position of the drying frame, local drying can be performed on different parts of the chemical fiber paper tube to be cut, thereby accurately controlling the local humidity of the chemical fiber paper tube and improving the bending and crack resistance of the chemical fiber paper tube.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 2 and Figure 3This utility model provides an embodiment of a chemical fiber paper tube anti-bending and cracking device, comprising a base plate 1, which serves as the basic support structure for the entire device. A fixing mechanism 2 is provided on the top of the base plate 1, and a top frame 3 is fixedly connected to the top of the base plate 1. A drying mechanism 4 is provided at the bottom of the top frame 3. A bearing plate 5 is fixedly connected to the top of the base plate 1, and the bearing plate 5 is used to place the chemical fiber paper tube and cooperate with a cutting device for cutting operations. The fixing mechanism 2 includes an adjusting component 21, which includes a slide rail 2101. The bottom of the slide rail 2101 is fixedly connected to the top of the base plate 1, and two sliders 2102 are slidably connected to the top of the slide rail 2101. Each slider 2102 has a support plate 2103 fixedly connected to its top. During device operation, the sliders 2102 drive the support plates 2103 to move synchronously. Each fixed plate 210 has multiple sliding grooves 211 inside. The external sliding rod 29 is slidably connected to the inside of the sliding groove 211. The top of the adjusting component 21 is slidably connected to two driving components 22. Each driving component 22 includes a mounting plate 2201. The mounting plate 2201 is used to mount the cylinder 2202. The bottom of the two mounting plates 2201 is fixedly connected to the top of the two support plates 2103 respectively. The cylinder 2202 is mounted on the far side of the two mounting plates 2201. The cylinder 2202 is the power source of the driving component 22. The driving end of the two cylinders 2202 is fixedly connected to a push rod. The near side of the two push rods is fixedly connected to the far side of the two moving disks 23 respectively. The cylinder 2202 drives the moving disk 23 to move through the push rod. The near side of the two driving components 22 is fixedly connected to the moving disk 23.

[0041] Specifically, in the adjusting component 21 of the fixing mechanism 2, the slide rail 2101 is fixed to the top of the base plate 1, and the two sliders 2102 on its top can drive the support plate 2103 to move synchronously. The slide groove 211 in the fixing plate 210 allows the slide rod 29 to slide. The two driving components 22 on the top of the adjusting component 21 have their mounting plates 2201 fixed to the top of the support plate 2103 for mounting the cylinder 2202 as a power source. The push rod of the cylinder 2202 is connected to the moving disk 23, which can drive the moving disk 23 to move, thereby realizing the relevant operations on the chemical fiber paper tube.

[0042] Reference Figures 1 to 3Multiple fixed blocks 24 are fixedly connected to adjacent sides of the two movable disks 23. The fixed blocks 24 are evenly distributed along the edge of the movable disks 23, allowing for synchronous displacement when the movable disks 23 move. Fixed shafts 25 are fixedly connected inside each of the fixed blocks 24, and rotating rods 26 are rotatably connected to the outside of each fixed shaft 25. The fixed shafts 25 are used to mount the rotating rods 26 and ensure that the rotating rods 26 can rotate flexibly around the fixed shafts 25. Fixed shafts 27 are rotatably connected inside each of the rotating rods 26, and fixed blocks 28 are fixedly connected to the outside of each fixed shaft 27. When the rotating rods 26 rotate, the fixed shafts 27 can... The sliding rod 29 is fixedly connected to the inside of each of the two adjusting components 21. When the two fixing blocks 28 are displaced, the sliding rod 29 can be displaced. At the same time, the sliding rod 29 can slide smoothly in the slide groove 211. The top of each of the two adjusting components 21 is fixedly connected to a fixing plate 210. The outside of the two fixing blocks 28 is slidably connected to the inside of the fixing plate 210. The adjacent sides of the two fixing blocks 28 are fixedly connected to a support ring 212. The support ring 212 is used to support the chemical fiber paper tube. When the sliding rod 29 slides in the slide groove 211, it will drive the support ring 212 to expand or contract outward, thereby achieving support and positioning of the chemical fiber paper tube.

[0043] Specifically, the first fixed block 24 moves synchronously with the moving disk 23. The first fixed shaft 25 inside the first fixed block 24 is installed and ensures that the rotating rod 26 can rotate flexibly around it. When the second fixed shaft 27 inside the rotating rod 26 rotates, it drives the second fixed block 28 to move. The slide rod 29 inside the second fixed block 28 moves with the second fixed block 28 and can slide smoothly in the slide groove 211. The fixed plate 210 at the top of the adjusting component 21 allows the second fixed block 28 to slide inside it. The support rings 212 on the adjacent side of the multiple second fixed blocks 28 are used to support the chemical fiber paper tube. When the slide rod 29 slides in the slide groove 211, it drives the support rings 212 to expand or contract, thereby supporting and positioning the chemical fiber paper tube.

[0044] Reference Figure 1 , Figure 2 and Figure 4The drying mechanism 4 includes a power assembly 41, which includes a positioning plate 4101. The bottom of the positioning plate 4101 is fixedly connected to the top right side of the top frame 3. A motor 4102 is installed on the left side of the positioning plate 4101. The positioning plate 4101 is used to install the motor 4102, which is the power source for the movement of the drying mechanism 4. A support plate 4103 is fixedly connected to the top left side of the top frame 3. A threaded rod 4104 is fixedly connected to the output end of the motor 4102. The internal thread of the threaded sleeve 42 is connected to the outside of the threaded rod 4104. The support plate 4103 is used to support the left side of the threaded rod 4104. The left side of the threaded rod 4104 is rotatably connected to the inside of the support plate 4103. The external thread of the power assembly 41 is connected to the threaded sleeve 42. The threaded rod 4104 rotates under the drive of the motor 4102. Through the threaded engagement with the threaded sleeve 42, the rotational motion of the motor 4102 is converted into the linear motion of the threaded sleeve 42.

[0045] A sliding block 43 is fixedly connected to the bottom of the threaded sleeve 42. The sliding block 43 slides within the sliding groove 410. A drying frame 44 is fixedly connected to the bottom of the sliding block 43. Two limiting brackets 45 are fixedly connected to the top of the drying frame 44. The limiting brackets 45 guide and limit the movement of the drying frame 44, ensuring that the drying frame 44 moves along a predetermined track and avoiding deviation or shaking. Two fans 46 are fixedly connected inside the drying frame 44. The air outlets of the fans 46 face the part of the chemical fiber paper tube to be dried. The working principle of the fans 46 is that the fan blades rotate to draw outside air into the drying frame 44, forming an airflow. Two electric heating meshes 47 are fixedly connected inside the drying frame 44. The electric heating meshes 47 are key structures for converting electrical energy into heat energy. They are made of high-temperature resistant and high-resistance materials such as nickel-chromium alloy wire. When current passes through the heating grid 47, the nickel-chromium alloy wire heats up, heating the cold air drawn in by the fan 46 into hot air, which is then blown onto the chemical fiber paper tube to dry it. A drying lamp 48 is fixedly connected to the top inside the drying frame 44. The infrared rays emitted by the drying lamp 48 can directly irradiate the surface of the chemical fiber paper tube, causing the paper tube to absorb the energy of the infrared rays and convert it into heat energy, thereby achieving local drying of the paper tube. Two limiting grooves 49 are opened on the top inside the top inside the top frame 3. The external of the limiting frame 45 is slidably connected to the inside of the limiting grooves 49. The limiting grooves 49 and the limiting frame 45 cooperate with each other to ensure the safe and stable movement of the drying frame 44. A sliding groove 410 is opened on the top inside the top inside the top frame 3. The external of the sliding block 43 is slidably connected to the inside of the sliding groove 410. The function of the sliding groove 410 is to provide a sliding track for the sliding block 43.

[0046] Specifically, the motor 4102 drives the threaded rod 4104 to rotate. When the threaded rod 4104 rotates, it converts the rotational motion into the linear motion of the threaded sleeve 42 through the threaded engagement with the threaded sleeve 42. The sliding block 43 at the bottom of the threaded sleeve 42 slides in the sliding groove 410 on the top side inside the top frame 3, driving the drying frame 44 below to move. The limiting frame 45 at the top of the drying frame 44 slides in the limiting groove 49 on the top side inside the top frame 3, ensuring the safe and stable movement of the drying frame 44. The fan 46 inside the drying frame 44 draws in air, and the electric heating grid 47 converts electrical energy into heat energy to heat the air, forming hot air to dry the chemical fiber paper tube. At the same time, the drying lamp 48 on the top side inside the drying frame 44 emits infrared rays, which directly irradiate the surface of the chemical fiber paper tube to achieve local drying.

[0047] Working principle: When using this anti-bending and cracking device for chemical fiber paper tubes, the chemical fiber paper tube can first be placed on the outside of the support ring 212. Then, the cylinder 2202 can be activated to drive the moving disk 23 to move. At this time, as the moving disk 23 moves, the fixed block 24 will move, which will cause the rotating rod 26 to rotate around the fixed shaft 25. As the rotating rod 26 rotates, the fixed shaft 27 will rotate, which will cause the fixed block 28 to slide inside the fixed plate 210. At this time, the sliding rod 29 will slide inside the sliding groove 211, which will cause the support ring 212 to expand outward, thus supporting one end of the chemical fiber paper tube. Then, the sliding rail 2101 will drive the slider 2102 on the other side to move, thus aligning the support ring 212 on the other side with the other end of the chemical fiber paper tube. Then, the above steps can be repeated to achieve the support and positioning of the chemical fiber paper tube.

[0048] Then, the cutting position is selected as needed, and the motor 4102 is started to drive the threaded rod 4104 to rotate, which in turn drives the threaded sleeve 42 to move. At this time, the sliding block 43 slides inside the sliding groove 410, which drives the drying frame 44 to move, which in turn drives the limiting frame 45 to slide inside the limiting groove 49, thus moving to the cutting position. At this time, the fan 46 draws in the outside air as cold air, which is then turned into hot air through the electric heating grid 47 to achieve local drying of the chemical fiber paper tube. At the same time, the drying lamp 48 is used to achieve local drying of the chemical fiber paper tube. Then, the cutting device installed on the top of the support plate 5 can be used to achieve positioning and cutting of the chemical fiber paper tube, so as to accurately control the humidity of the chemical fiber paper tube and achieve anti-bending and cracking.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
