Description

Technical Field

[0002] As an important industrial raw material, chemical fiber is widely used in many fields such as textiles, clothing, automobiles, and aerospace. With the development of the global economy and the improvement of people's living standards, the demand for chemical fiber continues to grow, while higher requirements are also being placed on its quality and performance. In recent years, the chemical fiber industry has continuously increased its investment in technological research and development, promoted the upgrading and innovation of production processes, in order to improve production efficiency, reduce costs, and improve product quality.

[0003] Traditional chemical fiber filament changing devices mainly rely on manual operation. Operators need to first remove the wound chemical fiber filaments and then load the empty roll into the machine. This method has many disadvantages. Because the wound chemical fiber filaments are heavy, it increases the difficulty and intensity of the operator's work. Moreover, it is easily affected by human factors, resulting in slow changing speed and affecting production efficiency.

[0004] Existing technology has improved the device by using a turntable drive. When a chemical fiber spool is wound up, the turntable rotates to exchange the wound spool with the empty spool, and at the same time cuts the chemical fiber filaments, so that the machine can continue to work with the empty spool. The wound spool is picked up and transported by a robotic arm. However, in actual use, new problems have arisen. The cost of the robotic arm is high, and it also requires high technical skills from the operators. The maintenance and upkeep of the winding device also require professional technicians and equipment, which increases the company's operating costs. Utility Model Content

[0032] 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.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The present invention provides an embodiment of a fiber filament production roll changing device, including a movable base 1, which can realize the overall movement function. A backrest 4 is fixedly connected to the top right side of the movable base 1 to provide a stable mounting base for other components on the device. A clamping mechanism 2 is provided on the top left side of the backrest 4 to realize the automated gripping and transfer operation of the fiber filament roll. A tray device 3 is provided on the top of the movable base 1 to receive and temporarily store the fiber filament roll. A support structure 5 is provided on the top left side of the backrest 4 to provide additional support to ensure stability during the transfer of the fiber filament roll.

[0034] The clamping mechanism 2 includes a guide rail 201, which provides a fixed trajectory for the movement of the slider 202. The right side of the guide rail 201 is fixedly connected to the top left side of the backrest 4. The slider 202 is slidably connected to the outer wall of the guide rail 201, which installs and drives the clamping components to adjust their positions. Gears 203 are rotatably connected to the front and rear sides of the bottom of the inner wall of the slider 202, enabling the synchronous and opposite movement of the two robotic arms 204. The two gears 203 are meshed together, and robotic arms 204 are fixedly connected to the bottom of each gear 203, directly contacting and clamping the chemical fiber roll. A telescopic rod 205 is rotatably connected to the front side of the bottom of the inner wall of the slider 202, providing power for the rotation of the front robotic arm 204. Fixed wheels 206 are rotatably connected to the left and right sides of the bottom of the telescopic rod 205, which extends... The telescopic motion of the retractor 205 is converted into the rotational motion of the robotic arm 204. Multiple fixed wheels 206 are fixedly connected to the robotic arm 204 on the front side. The slider 202 is equipped with a transmission mechanism 207, which provides power and transmission for the slider 202 to move along the guide rail 201. The transmission mechanism 207 includes a motor 2071, which serves as the power source for the transmission mechanism 207. The front side of the outer wall of the motor 2071 is fixedly connected to the rear side of the inner wall of the slider 202. The output end of the motor 2071 is fixedly connected to a gear 2072, which transmits the power of the motor 2071 to the guide rail 201. Multiple gear slots 2073 are opened on the top left and right sides of the guide rail 201, which mesh with the gear 2072 to realize the movement of the slider 202. The gear slots 2073 are meshed with the gear 2072.

[0035] Specifically, firstly, the base 1 is precisely moved to the position to be replaced, with the backrest 4 providing stable support; then, the motor 2071 of the transmission mechanism 207 drives the gear 2072 to mesh with the gear groove 2073 at the top of the guide rail 201, causing the slider 202 to slide precisely along the guide rail 201 to the position of the core axis; the telescopic rod 205 extends downward, driving the front robotic arm 204 to rotate clockwise around the gear 203 via the fixed wheel 206, and using the meshing linkage of the two gears 203 to drive the rear robotic arm... The robotic arm 204 rotates counterclockwise in sync, enabling it to close and grasp the yarn roll in opposite directions. Its inner anti-slip strip 7 can adaptively adjust the clamping force according to the diameter of the core. The motor 2071 reverses to drive the slider 202 back, simultaneously lifting the yarn roll. The tray device 3 rises to the designated height to receive the yarn roll, and the support structure 5 helps to maintain the horizontal posture of the yarn roll. After the tray device 3 rotates to the unloading position, the robotic arm 204 releases to unload the old roll, realizing the automatic winding function of chemical fiber yarn and improving the winding efficiency.

[0036] Reference Figure 1 , Figure 2 and Figure 4The tray device 3 includes multiple support rods 301, providing an installation base and stable support for the telescopic rod 302. The bottoms of the multiple support rods 301 are all fixedly connected to the top of the movable base 1. The tops of the multiple support rods 301 are slidably connected to the telescopic rod 302, allowing the height of the platform 303 to be adjusted by telescoping to adapt to different working conditions. The tops of the multiple telescopic rods 302 are fixedly connected to the same platform 303, which directly places and supports the chemical fiber roll. The bottom of the platform 303 is fixedly connected to multiple springs 304, which act as a buffer to reduce impact when supporting the chemical fiber roll. The bottoms of the multiple springs 304 are fixedly connected to the top of the movable base 1. Multiple guide wheels 6 are rotatably connected to the top left of the platform 303 to guide the chemical fiber roll to be accurately placed on the platform 303. Multiple anti-slip strips 7 are fixedly connected to the top of the platform 303 to increase the friction between the chemical fiber roll and the platform 303 to prevent the roll from slipping. The spacing between adjacent anti-slip strips 7 is equal.

[0037] Specifically, in the initial state, multiple support rods 301 are fixed to the top of the movable base 1, with telescopic rod 302 nested within them. When the clamping mechanism 2 moves the yarn roll to the top, the telescopic rod 302 extends synchronously, driving the platform 303 to rise to the receiving position. Multiple guide wheels 6 on the top left side of the platform 303, through their arc arrangement and free rolling characteristics, ensure that the yarn roll axis is aligned with the center of the platform 303. After the yarn roll is placed, the spring 304 provides cushioning due to the compression under load. At the same time, the anti-slip strips 7 evenly distributed on the top of the platform 303 are embedded in the grooves on the edge of the yarn roll, increasing friction to prevent slippage. After the yarn roll is removed, the spring 304 elastically recovers, pushing the platform 303 to rise, and the telescopic rod 302 synchronously retracts back to the initial state. This device, through its elastic support system, guiding and anti-slip coordination, and modular design, achieves automated receiving, cushioning protection, and precise positioning of yarn rolls of different specifications, improving the efficiency and quality of chemical fiber production.

[0038] Reference Figure 1 , Figure 2 and Figure 5 Multiple movable wheels 8 are rotatably connected to the front and rear sides of the inner wall of the slider 202. The rolling reduces the frictional resistance between the slider 202 and the guide rail 201. Slide grooves 9 are provided on the front and rear sides of the outer wall of the guide rail 201 to provide a sliding trajectory for the movable wheels 8 and constrain the movement direction of the slider 202. The multiple movable wheels 8 are slidably connected to the two sides of the corresponding slide grooves 9 respectively.

[0039] Specifically, when the motor 2071 drives the gear 2072 to mesh with the gear groove 2073 on the top of the guide rail 201, the slider 202 moves axially along the guide rail 201. At this time, multiple moving wheels 8 on the front and rear sides of the inner wall of the slider 202 are respectively embedded in the sliding grooves 9 on the front and rear sides of the guide rail 201. The rim of the moving wheel 8 and the inner walls on both sides of the sliding groove 9 form a rolling friction pair, which not only constrains the lateral displacement of the slider 202, but also converts the sliding friction into rolling friction. During the process of gripping and transferring the wire roll, the moving wheel 8 continuously rolls along the sliding groove 9 to ensure the stability of the slider 202's movement trajectory. At the same time, the rolling contact reduces component wear and extends the service life of the device.

[0040] Reference Figure 1 , Figure 2 and Figure 3 The support structure 5 includes a fixed rod 501, which connects and fixes the guide rail 201 to the backrest 4 to enhance the overall structural stability. Pads 502 are fixedly connected to both sides of the fixed rod 501, reducing pressure on the connecting parts by increasing the force-bearing area. Multiple screws 503 are threaded around the outer walls of both pads 502, firmly connecting the pads 502 to the guide rail 201 and the backrest 4 respectively. Multiple screws 503 at the top are threaded to the guide rail 201, and multiple screws 503 on the right side are threaded to the backrest 4. The top of the slider 202 is... A heat dissipation mesh 10 is provided on the side, which dissipates heat from components such as the motor 2071 during operation through a hollow structure. Screws 11 are threaded around the top of the heat dissipation mesh 10 to securely install the heat dissipation mesh 10 onto the slider 202. Multiple screws 11 are threadedly connected to the slider 202. A support plate 12 is fixedly connected to the left side of the outer wall of the slider 202 to provide a stable mounting base for the camera 13. The camera 13 is fixedly connected to the bottom of the support plate 12 to capture the position and status information of the chemical fiber roll in real time to assist the control system in making precise operations.

[0041] Specifically, during operation, the heat generated by components such as the motor 2071 is discharged through the hollow structure of the heat dissipation mesh 10, keeping the internal temperature of the slider 202 stable. At the same time, the camera 13 at the bottom of the support plate 12 on the left side of the outer wall of the slider 202 captures the chemical fiber roll and the surrounding environment in real time, transmits the images to the control system, locates the position of the roll, and cooperates with the clamping mechanism 2 to accurately complete the gripping action. The fixing of the screw 11 ensures that the heat dissipation mesh 10 does not loosen during the operation of the device, ensuring the stability of heat dissipation and camera functions.

[0042] Working principle: First, the entire device is smoothly moved to the location of the chemical fiber filament to be replaced. Then, the motor 2071 is started. The motor 2071 drives the slider 202 to move forward smoothly along the preset track until the robot arm 204 reaches directly above the chemical fiber filament. The telescopic rod 205 is operated to make the gripper of the robot arm 204 gradually close, thereby gripping the chemical fiber filament. After gripping, the slider 202 is driven again, which drives the robot arm 204 and the gripped chemical fiber filament to move backward smoothly along the track, realizing the automatic winding and transportation function of the chemical fiber filament. When the robot arm 204 moves to the top of the platform 303, the gripper of the robot arm 204 is released, and the chemical fiber filament falls accurately into the platform 303 under the action of gravity. Finally, the device is moved to the storage position to complete the storage of the chemical fiber filament.

[0043] Furthermore, during the process of changing the chemical fiber filament rolls, due to the diverse specifications of the chemical fiber filaments, the corresponding tray size also needs to be flexibly adapted. When the robotic arm 204 picks up a chemical fiber filament with a larger diameter and greater height and moves it above the platform 303 and places it there, the chemical fiber filament will exert downward pressure on the platform 303 through the guide wheel 6. Under this pressure, the telescopic rod 2 302 connected to the platform 303 will retract downward along the guide mechanism, and at the same time compress the spring 304 sleeved on the outside of the telescopic rod 2 302, causing the height of the platform 303 to decrease accordingly. Through this automatic adjustment process, the space height between the platform 303 and the upper structure is increased, thereby ensuring that the tray can smoothly place higher specification chemical fiber filaments, solving the problem of storage adaptation of chemical fiber filaments of different specifications.

[0044] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are 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.
