DETAILED DESCRIPTION

[0024] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0025] In one embodiment, Figures 1 to 4 shown.

[0026] The silk pressing rubber roller provided in this embodiment includes a first bearing seat 1 and a second bearing seat 2 opposite to each other in the horizontal direction. The first bearing seat 1 and the second bearing seat 2 are respectively provided with three-ring bearings 3 on their opposite inner sides. The middle rings 4 of the two or three-ring bearings 3 are respectively fixedly connected to the first bearing seat 1 and the second bearing seat 2. The inner rings 5 ​​of the two or three-ring bearings 3 are each provided with an insert 6 with a hexagonal hole. A core shaft 7 is penetrated and connected between the two or three-ring bearings 3. The part of the core shaft 7 contacting the two inserts 6 is a hexagonal rod 8. The core shaft 7 is provided with a hexagonal rod 8 along its axial direction. The inner support assembly 9 is evenly distributed at multiple locations, and the inner support assembly 9 includes three hinge seats 10 evenly distributed along the circumference of the core shaft 7 and an inner support member 11 rotatably connected to the hinge seat 10. An inner support plate 12 is rotatably connected to each inner support member 11 along the axial direction parallel to the core shaft 7. The three inner support plates 12 are evenly distributed along the circumferential direction, and a receiving area 13 is formed between two adjacent inner support plates 12. Springs 15 are respectively connected between the two ends of each inner support plate 12 and the outer rings 14 of the two or three ring bearings 3; the three inner support plates 1 2 is sequentially covered with a first flexible adhesive layer 16, a second flexible adhesive layer 17, a third flexible adhesive layer 18, and a fourth flexible adhesive layer 19 from the inside to the outside. The perimeters of the first flexible adhesive layer 16, the second flexible adhesive layer 17, the third flexible adhesive layer 18, and the fourth flexible adhesive layer 19 are equal. Three first embedded rods 20 are arranged between the first flexible adhesive layer 16 and the second flexible adhesive layer 17, three second embedded rods 21 are arranged between the second flexible adhesive layer 17 and the third flexible adhesive layer 18, and three second embedded rods 22 are arranged between the third flexible adhesive layer 18 and the fourth flexible adhesive layer 19. There are three third embedded rods 22, the radius of the first embedded rod 20, the second embedded rod 21, and the third embedded rod 22 decreases successively, and the three first embedded rods 20, the second embedded rod 21, and the third embedded rod 22 make the three inner protrusions 23 formed by the first flexible rubber layer 16, the second flexible rubber layer 17, and the third flexible rubber layer 18 respectively embedded in the three accommodating areas 13; the outer side of the first bearing seat 1 is provided with an electric cylinder 24 fixed relative to the first bearing seat 1, and the output end of the electric cylinder 24 and the core shaft 7 are coaxially connected through a coupling 25.

[0027] In this embodiment, the first bearing seat 1 and the second bearing seat 2 of the silk pressing rubber roller are fixed. A three-ring bearing 3 is connected to the first bearing seat 1, and a three-ring bearing 3 is also connected to the second bearing seat 2, and the connection point is the middle ring 4 of the three-ring bearing 3. That is, the middle ring 4 of the two three-ring bearings 3 is fixed, the inner ring 5 can rotate relative to the middle ring 4 of the three-ring bearing 3, and the outer ring 14 can also rotate relative to the middle ring 4 of the three-ring bearing 3. A core shaft 7 is connected through the two three-ring bearings 3, and the part of the core shaft 7 contacting the two inserts 6 is a hexagonal rod 8. The core shaft 7 is driven by the electric cylinder 24 to move along its own axis. In addition, the core shaft 7 is supported by the inner ring 5 of the three-ring bearing 3 through the insert 6. When the electric cylinder 24 drives the core shaft 7 to move horizontally to one side, the inner support member 11 is expanded outward by the action of the core shaft 7, so that the inner support members 11 at three locations are opened outward at the same time.

[0028] In this embodiment, unlike the structure of the traditional silk pressing rubber roller, the inner support member 11 at three locations is coated with the first flexible rubber layer 16, the second flexible rubber layer 17, the third flexible rubber layer 18, and the fourth flexible rubber layer 19 from the inside to the outside, that is, four layers of flexible rubber layers with equal circumferences. The first embedded rod 20, the second embedded rod 21, and the third embedded rod 22 are arranged between each layer. When in use, if the fourth flexible rubber layer 19 hardens, the fourth flexible rubber layer 19 can be directly cut open to remove the outer wrapping of the first flexible rubber layer 16, the second flexible rubber layer 17, and the third flexible rubber layer 18, so that the third flexible rubber layer 18 becomes the outermost flexible rubber layer. In coordination with this, the electric cylinder 24 drives the core shaft 7 to move horizontally to one side to support the third flexible rubber layer 18. Similarly, if the third flexible rubber layer 18 and the second flexible rubber layer 17 harden successively, they can also be cut open separately to make the inner flexible rubber layer become the outermost flexible rubber layer until the first flexible rubber layer 16. In this way, the surface hardening cycle of the silk-pressing rubber roller will be extended to nearly four times the original, and the service life will be increased by three times. In addition, unlike the traditional way of replacing the rubber roller, which will disrupt the yarn arrangement in the textile machine, the main body position of the silk-pressing rubber roller does not change when replacing the flexible rubber layer. It can be cut along the position of the embedded rod. After the embedded rod falls out, it will not be reused, so there is no need to rearrange the yarn.

[0029] In one embodiment, Figure 4 shown.

[0030] In the silk pressing rubber roller provided in this embodiment, the first flexible rubber layer 16, the second flexible rubber layer 17, the third flexible rubber layer 18, and the fourth flexible rubber layer 19 have the same thickness.

[0031] In this embodiment, the thicknesses of the first flexible adhesive layer 16, the second flexible adhesive layer 17, the third flexible adhesive layer 18, and the fourth flexible adhesive layer 19 are equal. Therefore, the wear resistance and hardening cycle of the first flexible adhesive layer 16, the second flexible adhesive layer 17, the third flexible adhesive layer 18, and the fourth flexible adhesive layer 19 are also equivalent.

[0032] In one embodiment, Figure 4 shown.

[0033] The silk pressing rubber roller provided in this embodiment has an inner support plate 12 provided with a hinge groove 26 , and the end of the inner support member 11 is rotatably connected to the hinge groove 26 .

[0034] In this embodiment, the inner support member 11 has two ends, one end is rotatably connected to the hinge seat 10, and the other end is rotatably connected to the hinge groove 26, so when the core shaft 7 moves along its axial direction, each inner support plate 12 can expand outward synchronously.

[0035] In one embodiment, Figure 3 and Figure 5 shown.

[0036] The silk pressing rubber roller provided in this embodiment has a first connecting semi-ring 27 located outside the middle ring 4 of the three-ring bearing 3 located on the side where the first bearing seat 1 is located, which is fixedly connected to the first connecting semi-ring 27, which is spliced ​​with the first bearing seat 1, and a first keyway 28 for the connecting key to be embedded is provided at the splicing point of the two. The circumferential profile of the first connecting semi-ring 27 is the same as the circumferential profile of the middle ring 4 of the three-ring bearing 3. The middle ring 4 of the three-ring bearing 3 located on the side where the second bearing seat 2 is located is fixedly connected to the second connecting semi-ring 29 located outside the middle ring 4, which is spliced ​​with the second bearing seat 2, and a second keyway 30 for the connecting key to be embedded is provided at the splicing point of the two. The circumferential profile of the second connecting semi-ring 29 is the same as the circumferential profile of the middle ring 4 of the three-ring bearing 3.

[0037] In this embodiment, the first connecting half ring 27 is fixedly connected to the middle ring 4 of the three-ring bearing 3 through a connecting key, and the second connecting half ring 29 is also fixedly connected to the middle ring 4 of the three-ring bearing 3 through a connecting key, thereby fixing the three-ring bearing 3 bodies at two locations through the first connecting half ring 27 and the second connecting half ring 29.

[0038] In one embodiment, Figure 3 shown.

[0039] The silk pressing rubber roller provided in this embodiment has three inner support components 9, one located near the first bearing seat 1, one located between the first bearing seat 1 and the second bearing seat 2, and one located near the second bearing seat 2.

[0040] In this embodiment, the internal support components 9 of the silk pressing rubber roller are provided at multiple locations. When the core shaft 7 moves laterally, the internal support components 9 at multiple locations are opened outward synchronously, so that each internal support plate 12 is always parallel to the core shaft 7 during the outward expansion process, thereby opening the flexible rubber layers that need to be opened among the first flexible rubber layer 16, the second flexible rubber layer 17, and the third flexible rubber layer 18.

[0041] In one embodiment, Figure 3 shown.

[0042] In the silk pressing rubber roller provided in this embodiment, the first embedded rod 20, the second embedded rod 21, and the third embedded rod 22 are all rigid rods.

[0043] In this embodiment, a first insert rod 20, a second insert rod 21, and a third insert rod 22 are disposed between the first flexible adhesive layer 16, the second flexible adhesive layer 17, the third flexible adhesive layer 18, and the fourth flexible adhesive layer 19. The fourth flexible adhesive layer 19, the third flexible adhesive layer 18, and the second flexible adhesive layer 17 can be cut along the track of the third insert rod 22, the second insert rod 21, and the first insert rod 20. As long as the track is followed, it is not easy to cut the inner flexible adhesive layer.

[0044] In this embodiment, an accommodation area 13 is formed between two adjacent inner support plates 12 of the silk pressing rubber roller. When the first flexible rubber layer 16, the second flexible rubber layer 17, and the third flexible rubber layer 18 are wrapped by the fourth flexible rubber layer 19, inner protrusions 23 embedded in the three accommodation areas 13 are formed at the placement positions of each embedded rod, and as the outer flexible rubber layer is abandoned and the inner flexible rubber layer is activated, the inner protrusions 23 gradually disappear. Through such a setting, the surface of the silk pressing rubber roller can always be close to the round roller.

[0045] In one embodiment, a textile machine includes a silk-pressing rubber roller as described above. Since the structure of the silk-pressing rubber roller is different from that of a traditional silk-pressing rubber roller, the inner support members 11 at three locations are sequentially coated with a first flexible rubber layer 16, a second flexible rubber layer 17, a third flexible rubber layer 18, and a fourth flexible rubber layer 19 from the inside to the outside, that is, four layers of flexible rubber layers with equal circumferences. A first embedded rod 20, a second embedded rod 21, and a third embedded rod 22 are arranged between each layer. When in use, if the fourth flexible rubber layer 19 hardens, the fourth flexible rubber layer 19 can be directly cut open to remove the outer wrapping of the first flexible rubber layer 16, the second flexible rubber layer 17, and the third flexible rubber layer 18, so that the third flexible rubber layer 18 becomes the outermost flexible rubber layer. In coordination with this, the electric cylinder 24 drives the core shaft 7 to move horizontally to one side to support the third flexible rubber layer 18. Similarly, if the third flexible rubber layer 18 and the second flexible rubber layer 17 are hardened successively, they can also be cut separately, so that the inner flexible rubber layer becomes the outermost flexible rubber layer, until the first flexible rubber layer 16. In this way, the surface hardening cycle of the silk-pressing rubber roller will be extended to nearly four times the original, and the service life will be increased by three times. In addition, unlike the traditional method of replacing the rubber roller, which will disrupt the yarn arrangement in the textile machine, the main body position of the silk-pressing rubber roller does not change when the flexible rubber layer is replaced. It can be cut along the position of the embedded rod. After the embedded rod falls out, it will not be reused, so there is no need to rearrange the yarn once.

[0046] Therefore, the frequency of replacing the silk pressing rubber roller of the textile machine will be significantly reduced, and each time the flexible rubber layer is replaced, there is no need to rearrange the yarn, which increases the production efficiency of the textile machine to a certain extent.

[0047] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
