Abstract
Description
Technical Field
[0001] This invention relates to the field of bio-fabric production technology, specifically to a biodegradable fabric production device. Background Technology
[0002] As an important category of green and environmentally friendly textile materials, biodegradable fabrics require a production process that balances environmental friendliness with processing precision. Cotton yarn carding is one of the core processes in biodegradable fabric production. The core function of carding machinery is to separate, straighten, and parallelize the fibers (such as cotton yarn and other base materials) used in biodegradable fabrics, while removing impurities and short fibers. This provides high-quality fiber slivers for subsequent spinning and weaving processes, directly affecting the final quality and performance of the biodegradable fabric.
[0003] However, in actual use, existing biodegradable fabric production equipment typically discharges yarn in a single form at the discharge position of the carding machine. This requires subsequent discharge of cylindrical or flat yarns to be stacked and laid out using corresponding equipment. Consequently, the same carding machine produces yarns of different shapes for discharge and stacking, making the switching between the discharge mechanism and the stacking equipment cumbersome and affecting production efficiency. On the other hand, depending on different production requirements, the stacking method and form of cylindrical and flat yarns require corresponding stacking equipment, making it inconvenient for the existing carding machine's discharge mechanism to handle multiple forms of stacking and laying.
[0004] To address the aforementioned issues, there is an urgent need to optimize existing biodegradable fabric production facilities. Summary of the Invention
[0005] The purpose of this invention is to provide a biodegradable fabric production device to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that the existing technical solutions are too simplistic and provides a solution that is significantly different from the existing technology.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a biodegradable fabric production device, comprising a substrate, a fixing block, and a second slider. A mounting base is installed at the bottom inner side of the substrate, and a combing mechanism is installed at the upper end of the mounting base. A mounting frame is fixed to the right side of the mounting base. From left to right, a conveyor belt mechanism, an adjusting component, and two mounting plates are sequentially installed on the top of the mounting frame. The two mounting plates are respectively fixed to the front and rear sides of the mounting frame. A first slider is slidably connected to the inner sides of both mounting frames via an electric push rod. An upper pressure roller is rotatably installed between the two first sliders. A lower pressure roller is located below the upper pressure roller and rotatably installed between the two mounting plates. A gear disc is sleeved on the front shaft of the lower pressure roller. A second gear disc meshes with the right side of the first gear disc. The second gear disc is rotatably installed on the front mounting plate via a motor. A sliding groove is formed on the front and rear walls of the top opening of the mounting frame. A slide frame is slidably arranged within the sliding groove. A roller is connected to the rear upper end of the slide frame via a motor. A positioning post is rotatably arranged on the right side of the slide frame. A stacking component is arranged inside the slide frame.
[0007] Preferably, a fixing block is installed on the right side of the front mounting plate, and a second slider is slidably connected to the inner side of the fixing block by a spring. The second gear plate is connected to the motor output end and is connected to the upper pressure roller and the fixing block through a pulley and a belt. The front shaft of the lower pressure roller is connected to the transmission structure in the conveyor belt mechanism through a pulley and a belt.
[0008] Preferably, the adjustment assembly includes a fixed frame and a laser sensor. The fixed frame is mounted on the top of the mounting frame. A screw rod is rotatably connected between the front and rear inner walls of the fixed frame via a motor. Two sliders are slidably connected to the outer side of the screw rod via threaded grooves. The two sliders are slidably disposed in the top opening of the fixed frame via top protrusions. A gathering strip is fixed to the lower end of each of the two sliders. A rotating wheel is rotatably mounted in the opening of each of the two gathering strips. A gear plate is fixed to the outer side of the top shaft of each of the two rotating wheels. A laser sensor is disposed on the left side of each of the two gathering strips and is mounted on the conveyor belt mechanism.
[0009] Preferably, the outer side of the screw rod has two threaded grooves, which are opened in opposite directions, and the two threaded grooves are used for the three-way relative movement of the slider.
[0010] Preferably, each of the two gathering strips has a semi-circular groove on one side of its opposite side, and the top of the front gathering strip is connected to the rotating wheel via a motor.
[0011] Preferably, the laser sensor is installed at the same level as the conveyor belt mechanism and the bottom of the gathering bar.
[0012] Preferably, the stacking assembly includes a slide plate, which is slidably mounted inside the slide frame opening via an electric push rod. A mounting ring is rotatably connected inside the circular opening of the slide plate. A geared disc is connected to the notch on the front side of the slide plate via a motor. A geared ring is meshed with the outer side of the geared disc. The geared ring is fixed to the bottom outer side of the mounting ring. A discharge pipe is connected to the inner side of the mounting ring via an electric push rod.
[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention uses a conveyor belt mechanism to transport cotton yarn, and simultaneously adjusts the distance between the upper and lower pressure rollers according to the system parameters in the controller, so that the transported cotton yarn is initially compacted. Furthermore, with the setting of the controller system parameters, the speed, stroke and position of the slide carriage are adjusted and controlled when it slides back and forth on the mounting frame, so as to realize the stacking and laying of cotton yarn in various forms.
[0014] This invention utilizes a screw rod to drive a slider in three-way relative movement, causing two gathering strips to move relative to each other and gather cotton yarn into a columnar shape using a conveyor belt mechanism. By setting parameters in the controller system, the installation ring rotates at different positions of the discharge pipe, resulting in stacking and laying of the columnar cotton yarn with varying radii of rotation. Simultaneously, the sliding speed, stroke, and position of the sliding plate within the carriage are adjusted according to the parameters set in the controller system, allowing for various stacking and laying methods and shapes of the columnar cotton yarn. Combined with the aforementioned flat discharge, the carding machine can discharge cotton yarn in two shapes. Furthermore, by adjusting the operating status and position of corresponding parts through parameters in the controller system, multiple stacking and laying methods are achieved for both types of cotton yarn.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1
[0018] Please see Figures 1 to 10This invention provides a technical solution: a biodegradable fabric production device, comprising a substrate 1, a fixing block 121, and a slider 122. A mounting base 2 is installed on the bottom inner side of the substrate 1, and a combing mechanism 3 is installed on the upper end of the mounting base 2. A mounting frame 4 is fixed to the right side of the mounting base 2. From left to right, a conveyor belt mechanism 5, an adjusting component 17, and two mounting plates 6 are sequentially installed on the top of the mounting frame 4. The two mounting plates 6 are respectively fixed to the front and rear sides of the mounting frame 4. Slider 7 is slidably connected to the inner sides of both mounting frames 4 via electric push rods. An upper pressure roller 8 is rotatably mounted between the two sliders 7. A lower pressure roller 9 is located below the upper pressure roller 8 and rotatably mounted between the two mounting plates 6. A gear disc 10 is sleeved on the front shaft of the lower pressure roller 9. A gear disc 10 is engaged with a gear disc 11 on its right side. The gear disc 11 is mounted on the front mounting plate 6 by a motor. The mounting frame 4 has a top opening and two sliding grooves 13 on its front and rear walls. A slide frame 14 is slidably arranged in the sliding groove 13. A roller 15 is connected to the rear side of the upper end of the slide frame 14 by a motor. A positioning post 16 is rotatably arranged on the right side of the slide frame 14. A stacking assembly 18 is arranged inside the slide frame 14. A fixing block 121 is installed on the right side of the front mounting plate 6. A slider 122 is slidably connected to the inside of the fixing block 121 by a spring. The gear disc 11 is connected to the motor output end and connected to the upper pressure roller 8 and the fixing block 121 by a pulley and a belt. The front shaft of the lower pressure roller 9 is connected to the transmission structure in the conveyor belt mechanism 5 by a pulley and a belt. When cotton yarn is laid out and stacked, the combed cotton yarn in the combing mechanism 3 enters the conveyor belt mechanism 5. The controller activates the servo motor to drive the gear disc 11 to rotate, which in turn drives the gear disc 10, the lower pressure roller 9, and the transmission mechanism in the conveyor belt mechanism 5 to rotate together via the belt and pulley. This causes the cotton yarn to be fed onto the lower pressure roller 9 by the conveyor belt mechanism 5. The controller activates the electric push rod according to the system parameters to push the slider 7 and the upper pressure roller 8 downward within the mounting plate 6, and adjusts the distance between the upper pressure roller 8 and the lower pressure roller 9 accordingly, so that the cotton yarn is fed onto the lower pressure roller 9. The cotton yarn is compacted between the upper pressure roller 8 and the lower pressure roller 9. Then, the operator manually guides the compacted cotton yarn between the two positioning columns 16. The servo motor is turned on by the controller and drives the slide 14 to slide back and forth in the slide groove 13 via the roller 15. The sliding speed of the slide 14 during reciprocation is adjusted by the system in the controller according to the cotton yarn conveying speed of the carding mechanism 3. At the same time, the system parameters in the controller are set to control and adjust the stroke and position of the slide 14 during reciprocation, so that the cotton yarn can be laid in various forms. Example 2
[0019] Based on Example 1, please refer to Figures 1 to 12The system includes a base 1, a fixing block 121, and a slider 122. A mounting base 2 is installed on the bottom inner side of the base 1. A combing mechanism 3 is installed on the upper end of the mounting base 2. A mounting frame 4 is fixed to the right side of the mounting base 2. From left to right, a conveyor belt mechanism 5, an adjusting assembly 17, and two mounting plates 6 are sequentially installed on the top of the mounting frame 4. The adjusting assembly 17 includes a fixing frame 171 and a laser sensor 177. The fixing frame 171 is installed on top of the mounting frame 4. A threaded rod 172 is rotatably connected between the front and rear inner walls of the fixing frame 171 via a motor. Two sliders 173 are slidably connected to the outer side of the threaded rod 172 via threaded grooves. The two sliders 173 are slidably positioned within the opening at the top of the fixing frame 171 via top protrusions. Two threaded grooves are formed on the outer side of the threaded rod 172. The screw rod 172 has two opposite threaded grooves, which are used for the relative movement of the sliders 173. Each slider 173 has a gathering bar 174 fixed to its lower end. Each gathering bar 174 has a semi-circular groove on one side of its opposite side. The top of the front gathering bar 174 is connected to a rotating wheel 175 via a motor. A rotating wheel 175 is rotatably installed inside the opening of each gathering bar 174. A gear disc 176 is fixed to the outer side of the top shaft of each rotating wheel 175. A laser sensor 177 is located on the left side of each gathering bar 174. The laser sensor 177 is mounted on the conveyor belt mechanism 5, and its installation position is at the same horizontal plane as the conveyor belt mechanism 5 and the bottom of the gathering bar 174. Two mounting plates 6 are respectively fixed on... On both the front and rear sides of the mounting bracket 4, two sliders 7 are slidably connected to the inner sides of the two mounting brackets 4 via electric push rods. An upper pressure roller 8 is rotatably mounted between the two sliders 7. A lower pressure roller 9 is located below the upper pressure roller 8 and is rotatably mounted between two mounting plates 6. A geared disc 10 is sleeved on the front shaft of the lower pressure roller 9. A geared disc 11 meshes with the right side of the geared disc 10. The geared disc 11 is rotatably mounted on the front mounting plate 6 via a motor. The top opening of the mounting bracket 4 has a sliding groove 13 on both the front and rear walls. A slide frame 14 is slidably mounted in the sliding groove 13. A roller 15 is connected to the rear side of the upper end of the slide frame 14 via a motor. A positioning post 16 is rotatably mounted on the right side of the slide frame 14. A stacking assembly 18 is installed inside the slide frame 14. The stacking assembly 18 includes a sliding plate 181. The slide plate 181 is slidably mounted inside the opening of the slide frame 14 via an electric push rod. The mounting ring 182 is rotatably connected inside the circular opening of the slide plate 181. The front notch of the slide plate 181 is connected to a gear plate 185 via a motor. A gear ring 184 is meshed on the outside of the gear plate 185. The gear ring 184 is fixed to the bottom outside of the mounting ring 182. The inner side of the mounting ring 182 is connected to the discharge pipe 183 via an electric push rod. A fixing block 121 is mounted on the right side of the front mounting plate 6. A slider 122 is slidably connected to the inner side of the fixing block 121 via a spring. The gear plate 11 is connected to the motor output end and is connected to the upper pressure roller 8 and the fixing block 121 via a pulley and a belt. The front shaft of the lower pressure roller 9 is connected to the transmission structure inside the conveyor belt mechanism 5 via a pulley and a belt. When the cotton yarn is being fed into a columnar shape, the controller activates the laser sensor 177 and simultaneously activates the electric push rod to adjust the position of the upper pressure roller 8 upwards. During the conveying process of the carded cotton yarn onto the conveyor belt mechanism 5, when the cotton yarn reaches the position of the laser sensor 177, the system in the controller receives the signal data from the laser sensor 177 and activates the servo motor connected to the grooved rod 172 and the front rotating wheel 175. When the servo motor drives the grooved rod 172 to rotate on the fixed frame 171, it causes the two sliders 173 to move relative to each other, and simultaneously drives the gathering strips 174 to move relative to the surface of the carding mechanism 3. This causes the cotton yarn on the carding mechanism 3 to be gathered into a columnar shape by the gathering strips 174. During this process, when the two gathering strips 174 are in contact... Subsequently, when the servo motor on the front gathering bar 174 drives the rotating wheel 175 to rotate, the front gear plate 176 drives the rear gear plate 176 and the rotating wheel 175 to rotate synchronously, so that the gathered columnar cotton yarn is conveyed to the lower pressure roller 9. At this time, the operator manually puts the columnar cotton yarn into the discharge pipe 183. With the parameter settings in the system of the controller, the installation ring 182 rotates to stack and lay the columnar cotton yarn at different radii of rotation when the discharge pipe 183 is in different positions. At the same time, with the parameter settings in the system of the controller, the sliding speed, stroke and position of the slide plate 181 in the slide frame 14 are adjusted accordingly, so that the columnar cotton yarn can be stacked and laid in various ways and forms.
[0020] Working principle: First, the operator starts the carding mechanism 3 through the controller to card the fibers of the substrate entering the carding mechanism 3. When the carded cotton yarn in the carding mechanism 3 enters the conveyor belt mechanism 5, the controller starts the servo motor to drive the toothed disc 11 to rotate. Through the belt and pulley, the toothed disc 10, the lower pressure roller 9 and the transmission mechanism in the conveyor belt mechanism 5 rotate together, so that the cotton yarn is fed into the lower pressure roller 9 by the conveyor belt mechanism 5. The controller starts the electric push rod according to the system parameters to push the slider 7 and the upper pressure roller 8 downward in the mounting plate 6, and adjusts the distance between the upper pressure roller 8 and the lower pressure roller 9 accordingly, so that the cotton yarn entering between the upper pressure roller 8 and the lower pressure roller 9 is compacted. At the same time, during the adjustment of the upper pressure roller 8, the elastic sliding of the slider 122 in the fixed block 121 ensures that the belt used for the transmission connection between the upper pressure roller 8 and the toothed disc 11 is always taut during the movement and adjustment of the upper pressure roller 8. After the cotton yarn is compacted between the upper pressure roller 8 and the lower pressure roller 9, the operator manually guides the compacted cotton yarn between the two positioning columns 16. The servo motor is activated by the controller, which drives the slide 14 to reciprocate within the slide groove 13 via the roller 15. The sliding speed of the slide 14 during reciprocation is adjusted by the system in the controller according to the cotton yarn conveying speed of the carding mechanism 3. At the same time, the system parameters in the controller are set to control and adjust the stroke and position of the slide 14 during reciprocation, so that the cotton yarn can be stacked in various forms. Based on the above, when columnar cotton yarn output is required, the controller first activates the laser sensor 177 and simultaneously activates the electric push rod to adjust the position of the upper pressure roller 8 upwards. During the process of the carded cotton yarn entering the conveyor belt mechanism 5 for conveying, when the cotton yarn is conveyed to the position of the laser sensor 177, the system in the controller receives the signal data from the laser sensor 177 and activates the servo motor connected to the screw groove rod 172 and the front rotating wheel 175. When the servo motor drives the screw groove rod 172 to rotate on the fixed frame 171, it causes the two sliders 173 to move relative to each other, and simultaneously drives the gathering strip 174 to move relative to the surface of the carding mechanism 3, so that the cotton yarn on the carding mechanism 3 is gathered into a columnar shape by the gathering strip 174. During this process, when the two gathering strips 174 are in contact, the servo motor on the front gathering strip 174 drives the rotating wheel 175 to rotate, which in turn drives the front toothed disc 176 to rotate. The rear gear plate 176 and the rotating wheel 175 rotate synchronously, so that the gathered columnar cotton yarn is conveyed to the lower pressure roller 9. At this time, the operator manually puts the columnar cotton yarn into the discharge pipe 183, and starts the motor connected to the gear plate 185 and the electric push rod connected to the slide plate 181 through the system in the controller. When the motor drives the gear plate 185 to rotate, it synchronously drives the gear ring 184 and the mounting ring 182 to automatically rotate and spread the columnar cotton yarn in the slide plate 181. At this time, in conjunction with the system parameters in the controller, the position of the discharge pipe 183 in the mounting ring 182 is adjusted by the electric push rod, so that the columnar cotton yarn can be stacked and spread with different radii of rotation stroke. At the same time, in conjunction with the system parameters in the controller, the sliding speed, stroke and position of the slide plate 181 in the slide frame 14 are adjusted by the electric push rod, so that the columnar cotton yarn can be stacked and spread in various forms.
