Description

Technical Field

[0001] This utility model relates to the field of POY paper core technology, and in particular to a wear-resistant and aging-resistant POY paper core. Background Technology

[0002] POY paper core refers to the paper core used in high-speed spinning and texturing machines for fiber filaments in the chemical fiber industry. It plays a key role in spinning and winding production and unwinding processing, and has excellent radial compressive strength, anti-burst deformation and oil absorption.

[0003] However, in existing equipment, when storing POY paper cores, the POY paper cores are easily affected by moisture in the air, causing them to become damp and age, which affects their use. Therefore, a wear-resistant and aging-resistant POY paper core is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wear-resistant and aging-resistant POY paper core.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant and aging-resistant POY paper core, comprising a POY paper core body and a support tube, wherein the outer wall of the support tube is provided with multiple sliding grooves, the support tube is provided with a support structure, and one side of the POY paper core body is provided with multiple connecting holes, each connecting hole is slidably connected to a drying tube, each drying tube is provided with a desiccant, one end of each drying tube is provided with a threaded hole, each threaded hole is threadedly connected to a first threaded rod, and one end of each first threaded rod is fixedly connected to a rotating disk.

[0006] As a further description of the above technical solution:

[0007] Each of the first threaded rods is slidably connected to a pressing disc, and one side of each pressing disc is in contact with one side of the POY paper core body.

[0008] As a further description of the above technical solution:

[0009] Each of the first threaded rods is movably provided with a spring, one end of each spring is fixedly connected to one side of the extrusion disc, and the other end is fixedly connected to one side of the rotating disc.

[0010] As a further description of the above technical solution:

[0011] The support structure includes a bidirectional threaded rod rotatably connected inside the support tube, with a knob fixedly connected to one end of the bidirectional threaded rod.

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

[0013] Each of the opposite threads of the bidirectional threaded rod is threaded with a movable ring, and each movable ring has multiple first connecting frames fixedly connected to its outer wall.

[0014] As a further description of the above technical solution:

[0015] Each of the sliding grooves is slidably connected to two moving rods. One end of each moving rod is rotatably connected to the corresponding first connecting frame, and the other end is rotatably connected to the second connecting frame.

[0016] As a further description of the above technical solution:

[0017] Two second connecting frames located on the same side are fixedly connected to one side of a support column. Each support column is fixedly connected to one side of a rubber pad. Each support column is in contact with the inner wall of the POY paper core body.

[0018] This utility model has the following beneficial effects:

[0019] 1. Compared with existing technologies, this wear-resistant and aging-resistant POY paper core, by setting up a drying tube, a first threaded rod, a rotating disk, a pressing disk, and a spring, slides the drying tube into the corresponding connecting hole, and then screws the first threaded rod into the corresponding threaded hole, so that the pressing disk on the first threaded rod abuts against one side of the POY paper core body and compresses the spring, squeezing and fixing the drying tube in the connecting hole. The desiccant inside the drying tube dries the POY paper core body, which helps to reduce the probability of the POY paper core body becoming damp and aging due to moisture in the air, and improves the service life of the POY paper core body.

[0020] 2. Compared with existing technologies, this wear-resistant and aging-resistant POY paper core, by setting up a bidirectional threaded rod, a knob, a moving ring, a first connecting frame, a moving rod, a second connecting frame, and a support column, inserts the support tube into the POY paper core body. Then, by rotating the knob, the knob drives the bidirectional threaded rod to rotate, which in turn drives the moving ring to move. The moving ring drives the moving rod to move through the first connecting frame, and the moving rod drives the corresponding support column to move through the second connecting frame. This causes the support column to abut against the inner wall of the POY paper core body, providing support to the inner wall of the POY paper core body. This helps to reduce the probability of the POY paper core body being accidentally bent or flattened. Attached Figure Description

[0033] 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.

[0034] Reference Figures 1 to 10 The present invention provides a wear-resistant and aging-resistant POY paper tube core, comprising a POY paper tube core body 1 and a support tube 3. The outer side wall of the support tube 3 is provided with multiple sliding grooves, and a support structure 4 is provided on the support tube 3. Multiple connection holes 2 are provided on one side of the POY paper tube core body 1.

[0035] To achieve drying, a drying tube 5 is slidably connected inside each connecting hole 2. Each drying tube 5 contains a desiccant, and one end of each drying tube 5 has a threaded hole. A first threaded rod 6 is threaded into each threaded hole, and a rotating disk 7 is fixedly connected to one end of each first threaded rod 6. An extrusion disk 8 is slidably connected to each first threaded rod 6, and a spring 9 is movably mounted on each first threaded rod 6. One end of each spring 9 is fixedly connected to one side of the extrusion disk 8, and the other end is fixedly connected to one side of the rotating disk 7. One side of the pressure plate 8 is in contact with one side of the POY paper core body 1. The drying tube 5 is slid into the corresponding connecting hole 2, and then the first threaded rod 6 is screwed into the corresponding threaded hole. The pressing plate 8 on the first threaded rod 6 presses against one side of the POY paper core body 1 and compresses the spring 9, pressing and fixing the drying tube 5 in the connecting hole 2. The desiccant inside the drying tube 5 dries the POY paper core body 1, which helps to reduce the probability of the POY paper core body 1 becoming damp and aging due to moisture in the air, and improves the service life of the POY paper core body 1.

[0036] To achieve the purpose of support, the support structure 4 includes a bidirectional threaded rod 401 rotatably connected inside the support tube 3. A knob 402 is fixedly connected to one end of the bidirectional threaded rod 401. Moving rings 403 are threaded onto the opposite threads of the bidirectional threaded rod 401. Multiple first connecting frames 404 are fixedly connected to the outer wall of each moving ring 403. Two moving rods 405 are slidably connected in each sliding groove. One end of each moving rod 405 is rotatably connected to a corresponding first connecting frame 404, and the other end is rotatably connected to a second connecting frame 406. A support column 407 is fixedly connected to one side of the two second connecting frames 406 located on the same side. Each support column 407 has a knob 402 fixedly connected to one side of each second connecting frame 406. A rubber pad is fixedly connected, and one side of each support column 407 is in contact with the inner wall of the POY paper core body 1. The support tube 3 is inserted into the POY paper core body 1, and then the knob 402 is turned. The knob 402 drives the bidirectional threaded rod 401 to rotate. The bidirectional threaded rod 401 drives the moving ring 403 to move. The moving ring 403 drives the moving rod 405 to move through the first connecting frame 404. The moving rod 405 drives the corresponding support column 407 to move through the second connecting frame 406, so that the support column 407 abuts against the inner wall of the POY paper core body 1, supporting the inner wall of the POY paper core body 1, which helps to reduce the probability of the POY paper core body 1 being accidentally bent or flattened.

[0037] Working principle: The drying tube 5 is slid into the corresponding connecting hole 2, and then the first threaded rod 6 is screwed into the corresponding threaded hole, so that the extrusion plate 8 on the first threaded rod 6 presses against one side of the POY paper core body 1 and compresses the spring 9, pressing and fixing the drying tube 5 in the connecting hole 2. The desiccant inside the drying tube 5 dries the POY paper core body 1, which helps to reduce the probability of the POY paper core body 1 becoming damp and aging due to moisture in the air, and improves the service life of the POY paper core body 1. Then, the support tube 3 is inserted into the POY paper core. Inside the main body 1, the knob 402 is rotated, which drives the bidirectional threaded rod 401 to rotate. The bidirectional threaded rod 401 drives the moving ring 403 to move. The moving ring 403 drives the moving rod 405 to move through the first connecting frame 404. The moving rod 405 drives the corresponding support column 407 to move through the second connecting frame 406, so that the support column 407 abuts against the inner wall of the POY paper core main body 1, supporting the inner wall of the POY paper core main body 1. This helps to reduce the probability of the POY paper core main body 1 being accidentally bent or flattened.
