Technical Field
[0001] This utility model relates to the field of spinning equipment technology, and in particular to a loading and unloading device for spinning components of a spinning machine. Background Technology
[0002] In the chemical fiber industry, the development of small spinning machines is mainly driven by scientific research needs, material innovation, and the improvement of production efficiency. They have played an important role, especially in the development of new materials and small-scale trial production. Compared with the stable production of large spinning equipment, small spinning machines are more responsible for the small-scale testing and experimental verification of differentiated fibers. As one of the important components of the spinning machine, the spinning component transforms the viscous polymer melt into fine streams with specific cross-sectional shapes through micropores, and then solidifies them through a cooling medium to form filaments.
[0003] Therefore, the loading and unloading of spinning components on small spinning machines is very frequent. These components typically weigh over ten kilograms and operate at temperatures around 280°C. Manual installation requires lifting and rotating the components simultaneously, making single-person operation impossible. Furthermore, manual installation makes it difficult to properly position the components, leading to poor adhesion and leakage, affecting spinning quality. There is also the risk of accidental drops due to human error, posing a risk of burns and equipment damage. Therefore, a new technical solution is urgently needed to address at least one of these problems. Summary of the Invention
[0004] In view of the above shortcomings, the purpose of this utility model is to provide a loading and unloading device for spinning components of a spinning machine, which solves the problem mentioned in the background art that the loading and unloading of spinning components on the spinning machine is very frequent, making it impossible for a single person to operate.
[0005] To achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted by this utility model is as follows: A loading and unloading device for a spinning assembly of a small spinning machine includes a base plate, a connecting plate is provided on the top left side of the base plate, an installation mechanism is provided on the top of the base plate, and a feeding mechanism is provided on the left side of the connecting plate. The installation mechanism includes a lifting cylinder, a main frame is provided at the lifting end of the lifting cylinder, a positioning rod is fixedly installed at the top of the main frame, two sets of positioning rods are provided, deep groove ball bearings are provided at the upper and lower ends of the two sets of positioning rods, locking sleeves are fixedly installed on the outer rings of the two sets of deep groove ball bearings, a rotating handle is provided on the outer surface of the two sets of locking sleeves, and a first chuck disc is fixedly installed at the top of the two sets of locking sleeves.
[0006] As a preferred technical solution, the connecting plate has sliding grooves on its front and rear sides, and sliding rods are provided inside the two sets of sliding grooves. The main frame is slidably installed on the outer surface of the two sets of sliding rods.
[0007] As a preferred technical solution, the feeding mechanism includes a fixing plate, which is disposed on the front and rear sides of the connecting plate. A first motor is disposed on the outer side of one set of fixing plates, and a first lead screw is fixedly installed at the output end of the first motor. The first lead screw is rotatably installed on the inner side of the two sets of fixing plates. A first guide rod is also disposed on the inner side of the two sets of fixing plates, and the first guide rod is disposed directly below the first lead screw.
[0008] As a preferred technical solution, a movable plate is threadedly connected to the outer surface of the first lead screw, and the movable plate is also slidably installed on the outer surface of the first guide rod. A movable groove is provided at the top of the movable plate, and a second lead screw is rotatably installed inside the movable groove. A second guide rod is also provided inside the movable groove, and the second guide rod is located directly below the second lead screw.
[0009] As a preferred technical solution, the left end of the second lead screw is fixedly installed at the output end of the second motor, and a slider is threadedly connected to the outer surface of the second lead screw. The slider is also slidably installed on the outer surface of the second guide rod. A multi-stage lifting rod is provided at the bottom end of the slider, and a second chuck disk is provided at the lifting end of the multi-stage lifting rod.
[0010] As a preferred technical solution, the substrate is provided with movable wheels at the four corners of its bottom end.
[0011] As a preferred technical solution, the height of the locking sleeve is the same as the height of the positioning rod, and the diameter of the positioning rod is the same as the inner diameter of the deep groove ball bearing.
[0012] Compared with traditional technical solutions, the beneficial effects of this utility model are: 1) By setting up an installation mechanism, the main frame is raised and lowered by a lifting cylinder. The positioning rod at the top of the main frame, together with the locking sleeve, rotating handle and the first claw plate, can accurately grab the spinning component and realize the lifting and rotating locking operations. This design realizes the automation of loading and unloading of the spinning component, avoids the tedious operation of manually lifting and rotating to lock at the same time, solves the problem that a single person cannot complete the installation, and at the same time reduces the intensity of manual operation and improves loading and unloading efficiency.
[0013] 2) By setting up a feeding mechanism, the first motor drives the first lead screw to rotate, causing the movable plate to slide on the first guide rod, achieving initial horizontal positioning. Then, the second motor drives the second lead screw to rotate, causing the slider to slide on the second guide rod. In conjunction with the multi-stage lifting rod, the second claw plate is driven to make precise vertical adjustment. Through this series of designs, the spinning assembly is accurately positioned and stably gripped during loading and unloading. This avoids the situation where the spinning assembly is not easily straightened during manual installation, resulting in poor adhesion and leakage of slurry, thus ensuring the spinning quality. At the same time, it also effectively prevents the assembly from falling due to human error during installation, thereby avoiding the risk of personnel burns and equipment damage.

[0016] The present invention will now be further described with reference to the accompanying drawings.
[0017] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0018] Please refer to Figures 1-5 This utility model provides a loading and unloading device for a spinning assembly of a spinning machine, comprising a base plate 1, a connecting plate 2 disposed on the top left side of the base plate 1, a mounting mechanism 4 disposed on the top of the base plate 1, a feeding mechanism 5 disposed on the left side of the connecting plate 2, and movable wheels 6 disposed at the four corners of the bottom of the base plate 1. The mounting mechanism 4 includes a lifting cylinder 401, a main frame 402 disposed at the lifting end of the lifting cylinder 401, and sliding grooves 201 provided on the front and rear sides of the connecting plate 2. Sliding rods 3 are disposed inside the two sets of sliding grooves 201, and the main frame 402 is slidably mounted on the outer surface of the two sets of sliding rods 3. A positioning rod 403 is fixedly installed at the top of the main frame 402. There are two sets of positioning rods 403. Deep groove ball bearings 404 are installed at the upper and lower ends of the two sets of positioning rods 403. Locking sleeves 405 are fixedly installed on the outer ring of the two sets of deep groove ball bearings 404. The height of the locking sleeves 405 is the same as the height of the positioning rods 403. The diameter of the positioning rods 403 is the same as the inner diameter of the deep groove ball bearings 404. There are two sets of locking sleeves 405. Rotating handles 406 are provided on the outer surface of the two sets of locking sleeves 405. A first chuck disc 407 is fixedly installed at the top of the two sets of locking sleeves 405.
[0019] In this design, the main frame 402 is driven to vertically rise and fall along the slide bar 3 by the lifting cylinder 401, achieving precise height adjustment and stable lifting effect for the spinning assembly. The double positioning rod 403 structure, in conjunction with the deep groove ball bearing 404, enables the first claw plate 407 to quickly lock or release the spinning assembly via the rotation of the locking sleeve 405. The rotating handle 406 drives the locking sleeve 405 to rotate around the positioning rod 403, achieving automatic alignment of the spinning assembly's threads with the spinning box's groove. Furthermore, the low friction of the deep groove ball bearing 404 ensures easy operation of the rotating handle 406, significantly reducing manual labor intensity. Secondly, the first claw plate 407 and the locking sleeve 405 are coaxially rigidly connected, achieving anti-deflection during the spinning assembly installation process through synchronous rotation. The guiding structure of the slide bar 3 and the slide groove 201 enhances the stability of the main frame 402 during lifting, effectively avoiding the risk of swaying of the spinning assembly during the lifting process.
[0020] like Figures 1-3 As shown, the feeding mechanism 5 includes fixed plates 501, which are disposed on the front and rear sides of the connecting plate 2. A first motor 502 is disposed on the outer side of one set of fixed plates 501. A first lead screw 503 is fixedly installed at the output end of the first motor 502. The first lead screw 503 is rotatably mounted on the inner side of the two sets of fixed plates 501. A first guide rod 504 is also disposed on the inner side of the two sets of fixed plates 501. The first guide rod 504 is disposed directly below the first lead screw 503. A movable plate 505 is threadedly connected to the outer surface of the first lead screw 503. The movable plate 505 is also slidably mounted on the outer surface of the first guide rod 504. The top of the movable plate 505 is provided with a movable groove 506. A second lead screw 508 is rotatably installed inside the movable groove 506. A second guide rod 509 is also provided inside the movable groove 506. The second guide rod 509 is located directly below the second lead screw 508. The left end of the second lead screw 508 is fixedly installed at the output end of the second motor 507. A slider 510 is threadedly connected to the outer surface of the second lead screw 508. The slider 510 is also slidably installed on the outer surface of the second guide rod 509. A multi-stage lifting rod 511 is provided at the bottom end of the slider 510. A second chuck disk 512 is provided at the lifting end of the multi-stage lifting rod 511.
[0021] In this design, the first motor 502 drives the first lead screw 503 to rotate, causing the movable plate 505 to move horizontally along the first guide rod 504, thus achieving the positioning effect of the second gripper disk 512 in the front-back direction. The second motor 507 drives the second lead screw 508 to rotate, and the slider 510 slides along the second guide rod 509, enabling flexible adjustment of the second gripper disk 512 in the left-right direction. Furthermore, the telescopic movement of the multi-stage lifting rod 511 achieves multi-stage height adjustment of the second gripper disk 512 in the vertical direction. The dual guiding structure of the first guide rod 504 and the second guide rod 509 ensures the stability of the movable plate 505 and the slider 510 during movement, effectively preventing the second gripper disk 512 from shifting. Since the second gripper disk 512 and the multi-stage lifting rod 511 are rigidly connected, the three-axis linkage control, in conjunction with the second gripper disk 512, achieves the gripping effect of the spinning assembly, significantly improving loading and unloading efficiency.
[0022] The working principle of the loading and unloading device of this utility model is as follows: First, the first motor 502 drives the first lead screw 503 to rotate, causing the movable plate 505 to move horizontally along the first guide rod 504. The second motor 507 drives the second lead screw 508 to rotate, causing the slider 510 to slide along the second guide rod 509. The multi-stage lifting rod 511 performs vertical telescopic movement, enabling the second gripper disk 512 to achieve three-dimensional spatial positioning. The first guide rod 504 and the second guide rod 509 together ensure the accuracy of the movement trajectory. The second gripper disk 512 completes the gripping of the spinning assembly. When the first... When the second jaw plate 512 places the spinning assembly on the first jaw plate 407 and releases it, the first jaw plate 407 simultaneously clamps the spinning assembly. Next, the lifting cylinder 401 drives the main frame 402 to move vertically along the slide bar 3, causing the positioning rod 403 to rise and fall to the target height. The rotating handle 406 drives the locking sleeve 405 to rotate around the positioning rod 403. The deep groove ball bearing 404 achieves low-resistance rotation, enabling the first jaw plate 407 to complete the locking or releasing action of the spinning assembly. The slide bar 3 and the slide groove 201 cooperate to ensure the stability of the main frame 402 during the lifting process.
