Description

A type of internal support clamp for chemical fiber filament reels Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for chemical fiber production, specifically to an internal support clamp for chemical fiber spools, which is particularly suitable for automated clamping, rotating and placing operations in conjunction with an image acquisition system. Background Technology

[0002] In the production of synthetic fibers, a large number of synthetic fiber filaments are wound on spools, requiring quality inspection and identification. Currently, defect detection on synthetic fiber filament spools is mostly done manually. This method is not only labor-intensive and its accuracy decreases with the worker's working hours, but it also easily causes additional damage to the synthetic fiber filament spools during the inspection process. In emerging image recognition systems, the filament spools are required to rotate stably and at multiple angles during image capture. Traditional gripping methods cannot meet the dual requirements of precise positioning and non-destructive clamping. Therefore, there is an urgent need for a fixture device with a reasonable structure, convenient operation, and the ability to automate gripping, rotating, and placing without damaging the filament spools. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a fiber filament reel internal support clamp.

[0004] This utility model is achieved through the following technical solution:

[0005] A chemical fiber filament reel internal support clamp includes an electric telescopic rod with guide rods, a telescopic rod connecting flange, and a telescopic rod fixing frame. The electric telescopic rod with guide rods has a retractable rod inside, and guide rods are symmetrically arranged on both sides of the retractable rod, allowing the guide rods to slide along a reel mounted in the middle of the electric telescopic rod with guide rods. A first servo motor is mounted at the right end of the telescopic rod connecting flange, and a second servo motor is provided to control the electric telescopic rod with guide rods. The second servo motor is covered by a U-shaped protective cover, which is fixedly installed to the telescopic rod connecting flange. The other end of the electric telescopic rod with guide rods is a telescopic rod fixing frame, and a third servo motor is housed within the telescopic rod fixing frame. The telescopic rod fixing frame and the third servo motor are mounted on one end of a chassis. The other end of the chassis is a guide groove cover plate, which houses a guide rotating disk with protruding support claws.

[0006] Preferably, the first servo motor is connected to the entire mechanism by a telescopic rod connecting flange, and the protective cover outside the first servo motor is fixedly assembled with the telescopic rod connecting flange.

[0007] Preferably, the electric telescopic rod with guide rod is provided with two guide rods for guidance.

[0008] Preferably, the motor shaft of the third servo motor is fixedly connected to a guide rotating disk, thereby controlling the rotation of the guide rotating disk. The guide groove of the guide rotating disk drives the protruding support claw, and the guide groove of the guide groove cover plate guides it to realize the opening and closing of the internal support clamp.

[0009] Preferably, the protruding claws are three-claw structures, evenly arranged around the central axis of the clamp body, and the contact surfaces between the protruding claws and the chemical fiber filament paper tubes are provided with protruding rubber to increase friction.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention employs an internal support clamping method, effectively avoiding additional damage to the chemical fiber spool. The clamping position is central, the device has a compact structure, and a high degree of automation, making it suitable for efficient identification and detection of batches of spools. The protruding claw structure allows for multi-point contact with the inner wall of the paper tube after opening, increasing clamping friction and ensuring clamping stability. This reduces the risk of paper tube deformation while improving the clamp's control over the spool during rotation, making it particularly suitable for applications requiring high-precision image acquisition and positioning. It overcomes the limitations of manual handling and inspection. Through the coordination of the gripping, telescopic, and rotating parts, the rotating part drives the entire assembly to rotate, the telescopic part controls extension and retraction, and the gripping part is responsible for gripping the spool for stable clamping during inspection. This invention, with its internal support clamping, allows for omnidirectional image acquisition of the spool during inspection. Attached Figure Description

[0018] 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.

[0019] Please refer to Figures 1-5. This utility model provides a technical solution:

[0020] A fiber spool internal support clamp includes an electric telescopic rod 4 with guide rods, a telescopic rod connecting flange 2, and a telescopic rod fixing frame 5. The electric telescopic rod 4 with guide rods has a telescopic rod inside, and guide rods are symmetrically arranged on both sides of the telescopic rod. The guide rods make the extension and retraction of the clamp more stable and provide guidance during extension and retraction, allowing the guide rods to slide along the spool mounted in the middle of the electric telescopic rod 4 with guide rods. A first servo motor 1 is mounted on the right end of the telescopic rod connecting flange 2. The first servo motor 1 controls the rotation of the entire clamp, facilitating all-around inspection when testing the clamped spool. The electric telescopic rod 4 controls the second servo motor 3. The second servo motor 3 is covered with a U-shaped protective cover, which is fixedly installed to the telescopic rod connecting flange 2. The other end of the electric telescopic rod 4 with guide rod is the telescopic rod fixing frame 5. The third servo motor 6 is installed inside the telescopic rod fixing frame 5. The telescopic rod fixing frame 5 and the third servo motor 6 are installed at one end of the chassis 7. The other end of the chassis 7 is the guide groove cover plate 9. The guide groove cover plate 9 has a guide rotating disk 8 inside. The guide rotating disk 8 is equipped with a protruding support claw 10. Through the internal support design, the protruding support claw 10 supports and clamps the wire spool, which further reduces the damage to the wire spool.

[0021] Preferably, the first servo motor 1 is connected to the entire mechanism by the telescopic rod connecting flange 2. The protective cover outside the first servo motor 1 is fixedly assembled with the telescopic rod connecting flange 2. The telescopic rod connecting flange 2 plays a connecting role so that the entire fixture can be rotated by driving the first servo motor 1.

[0022] Preferably, the electric telescopic rod 4 with guide rods is provided with two guide rods for guidance. The provision of guide rods further increases the stability of guidance, making the clamp extend and retract more smoothly.

[0023] Preferably, the motor shaft of the third servo motor 6 is fixedly connected to the guide rotating disk 8, thereby controlling the rotation of the guide rotating disk 8. The guide groove of the guide rotating disk 8 drives the protruding support claw 10, which is guided by the guide groove of the guide groove cover plate 9, realizing the opening and closing of the internal support clamp. The internal support design protects the chemical fiber spool that needs to be clamped. At the same time, the protruding support claw 10 can fit tightly with the paper tube of the spool to form a reliable clamp.

[0024] Preferably, the protruding claw 10 has a three-claw structure and is evenly arranged around the central axis of the clamp body. The contact surface between the protruding claw 10 and the chemical fiber filament paper tube is provided with protruding rubber to increase friction. The presence of the protruding rubber further prevents slippage and makes the clamping of the filament more stable.

[0025] Preferably, a disc is installed between the electric telescopic rod 4 with guide rod and the telescopic rod fixing frame 5. The disc is located in the middle part of the electric telescopic rod 4 with guide rod, and the telescopic rod connecting flange 2 is concentric with the disc.

[0026] Workflow: When the overhead trolley carrying the chemical fiber filament disc moves to the designated detection position, a start detection signal is triggered. The second servo motor 3 controls the electric telescopic rod 4 to extend the end component of the telescopic rod. After extending to the set position, the third servo motor 6 starts to operate, driving the guide rotating disk 8 to rotate in the designated direction of the guide groove cover plate 9, thereby realizing the radial expansion of the protruding claw 10. When the protruding claw 10 is expanded to the set opening, it fits tightly with the paper tube of the chemical fiber filament disc, forming a reliable clamp. At this time, the second servo motor 3 controls the electric telescopic rod 4 to lift the end component of the telescopic rod and the chemical fiber filament disc from the overhead trolley and retract them to the designated detection position. The camera at the detection position begins to take pictures of the chemical fiber filament disc. After one picture is taken, the first servo motor 1 drives all components of the telescopic rod connecting flange 2 and the chemical fiber filament disc to rotate 90° and stop for ten seconds. During this period, the camera at the detection position continues to take pictures of the chemical fiber filament disc at this angle. Similarly, after rotating the filament spool 360° and stopping, the image of the filament spool is captured. The second servo motor 3 controls the electric telescopic rod 4 to extend the end assembly of the telescopic rod and the filament spool until it returns to the original position of the overhead shuttle. The third servo motor 6 drives the guide rotating disk 8 to rotate in the specified direction along the guide groove cover plate 9, thereby achieving the radial closure of the protruding claw 10, releasing the filament spool. The second servo motor 3 controls the electric telescopic rod 4 to retract the end assembly of the telescopic rod, completing the gripping of the filament spool.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
