Abstract
Description
Technical Field
[0001] This utility model relates to the field of stretching roller technology, specifically an axial stretching roller. Background Technology
[0002] Axial stretching rollers mainly eliminate wrinkles generated in materials (such as films, paper, and fabrics) during operation by applying axial force to them, allowing the materials to run smoothly. Their working principle is based on the mechanical properties of the materials. When the materials pass through the stretching rollers, the rollers generate tensile force on the edges or local areas of the materials through their own structural design.
[0003] In existing axial stretching rollers, the surface silicone strips are typically fixed individually with screws. During the use of the axial stretching roller, multiple silicone strips usually wear out simultaneously, requiring the removal of multiple screws to replace the silicone strips, which is inconvenient. Existing axial stretching shafts are generally a single unit. Since the roller body is in long-term contact with the workpiece, it is prone to wear, and replacement requires the entire unit, which is wasteful. Therefore, to address the above problems, an axial stretching roller is proposed. Utility Model Content
[0004] The purpose of this invention is to provide an axially spreading roller to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An axially extending roller includes a roller body. A first limiting groove is formed on the left side of the roller body, and a threaded groove is formed on one side of the roller body outside the first limiting groove. A second limiting groove is formed on the outer side of the roller body outside the threaded groove. A connecting groove is formed at the first end of the roller body inside the first limiting groove. A first fixing groove is formed inside the roller body above the connecting groove. A limiting shell is slidably connected inside the first limiting groove. A silicone strip that is slidably connected to the second limiting groove is fixedly connected to the outer side of the limiting shell. A rotating shaft is slidably connected inside the connecting groove. A fixing strip that is fixedly connected inside the first fixing groove is fixedly connected to the outer side of the rotating shaft.
[0007] Preferably, a threaded ring is spirally connected inside the threaded groove, a fixing cover is fixedly connected to the left side of the threaded ring, a second fixing groove is opened inside the fixing cover, a limiting plate that is slidably connected to the second fixing groove is fixedly connected to the outside of the rotating shaft, and a fixing ring that is slidably connected to the first limiting groove is fixedly connected to the right side of the limiting plate.
[0008] Preferably, the right side of the fixing ring is tightly fitted with the left side of the limiting shell, the outer diameter of the fixing ring is the same as the outer diameter of the limiting shell, and the inner sides of the first limiting groove on the outer side of the fixing ring and the limiting shell are fitted together.
[0009] Preferably, the second limiting groove and the silicone strip are a set, and there are a total of six sets of the second limiting groove and the silicone strip, which are evenly distributed inside the roller body with the center of the roller body as the center.
[0010] Preferably, the lengths of the threaded ring and the fixed ring are matched, and the internal dimensions of the second fixed groove and the external dimensions of the limiting plate are matched.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, by setting components such as the first limiting groove, threaded groove, second limiting groove, limiting shell, and silicone strip, firstly, rotating the fixing cover causes the threaded ring to rotate together, causing the threaded ring and threaded groove to separate, thus separating the fixing cover and the roller body. Then, holding the rotating shaft, the rotating shaft is pulled out from the connecting groove. At this time, the fixing strip is also pulled out from the first fixing groove. The first fixing groove and the fixing strip mainly play a fixing role, ensuring that while the rotating shaft rotates, the roller body is driven to rotate through the fixing strip and the first fixing groove. When the rotating shaft is pulled out to the left, it also drives the limiting plate to move. The limiting plate causes the fixing ring and the limiting shell to separate and fix. The ring will disengage from the first limiting groove, and then a silicone strip can be pulled to the left to move. This silicone strip will drive the limiting shell to move. As the limiting shell is removed from the first limiting groove, it will also drive all the silicone strips to be removed from the second limiting groove. This achieves the effect of replacing all the silicone strips at once, eliminating the need to remove screws multiple times to replace each silicone strip individually. This solves the problem that existing axial stretching rollers typically use screws to independently fix each silicone strip, and during the use of the axial stretching roller, multiple silicone strips will wear out at the same time, requiring the removal of multiple screws to replace the silicone strips, which is quite inconvenient.
[0013] 2. In this utility model, after the fixed cover and the roller body are separated, not only can the silicone strip be replaced, but the rotating shaft can also be directly pulled out from the connecting groove to replace the roller body separately, thereby reducing the cost of use. This solves the problem that the existing axial extension shaft is generally a whole, and the roller body is prone to wear due to long-term contact with the processed products. It is wasteful to replace the whole roller body when replacing it. Attached Figure Description

[0023] Please see Figure 1-5 This utility model provides a technical solution:
[0024] An axially extending roller includes a roller body 1. A first limiting groove 2 is provided on the left side of the roller body 1. A threaded groove 3 is provided on one side of the roller body 1 outside the first limiting groove 2. A second limiting groove 4 is provided on the outer side of the roller body 1 outside the threaded groove 3. A connecting groove 5 is provided at the first end of the roller body 1 inside the first limiting groove 2. A first fixing groove 6 is provided inside the roller body 1 above the connecting groove 5. A limiting shell 7 is slidably connected inside the first limiting groove 2. A silicone strip 8 that is slidably connected to the second limiting groove 4 is fixedly connected to the outer side of the limiting shell 7. A rotating shaft 9 is slidably connected inside the connecting groove 5. A fixing strip 10 located inside the first fixing groove 6 is fixedly connected to the outer side of the rotating shaft 9.
[0025] A threaded ring 11 is helically connected inside the threaded groove 3. A fixing cover 12 is fixedly connected to the left side of the threaded ring 11. A second fixing groove 13 is opened inside the fixing cover 12. A limiting plate 14 that is slidably connected to the second fixing groove 13 is fixedly connected to the outside of the rotating shaft 9. A fixing ring 15 that is slidably connected to the first limiting groove 2 is fixedly connected to the right side of the limiting plate 14. The right side of the fixing ring 15 is tightly fitted to the left side of the limiting shell 7. The outer diameter of the fixing ring 15 is the same as the outer diameter of the limiting shell 7. The inner side of the first limiting groove 2 on the outside of the fixing ring 15 and the limiting shell 7 are in contact with each other. The retaining ring 15 presses against the limiting shell 7, which prevents the silicone strip 8 from shaking within the second limiting groove 4. The second limiting groove 4 and the silicone strip 8 form a group, and there are six groups of the second limiting groove 4 and silicone strip 8. They are evenly distributed inside the roller body 1 with the center of the roller body 1 as the center. The multiple groups of second limiting grooves 4 can ensure that each silicone strip 8 has a fixed position, thus ensuring the stability of the silicone strip 8 when it is stretched. The lengths of the threaded ring 11 and the retaining ring 15 are matched, and the internal dimensions of the second retaining groove 13 and the external dimensions of the limiting plate 14 are matched.
[0026] Workflow: When an axial stretching roller is needed, the rotating shaft 9 and the fixing strip 10 drive the roller body 1 and silicone strip 8 to rotate, stretching the workpiece. When the silicone strip 8 wears, first rotate the fixing cover 12, which drives the threaded ring 11 to rotate together, separating the threaded ring 11 from the threaded groove 3, thus separating the fixing cover 12 from the roller body 1. Then, hold the rotating shaft 9 and pull it out of the connecting groove 5. At this time, the fixing strip 10 will also be pulled out of the first fixing groove 6. The first fixing groove 6 and the fixing strip 10 mainly serve a fixing function, ensuring that while the rotating shaft 9 rotates, the roller body 1 rotates through the fixing strip 10 and the first fixing groove 6. When the rotating shaft 9 is pulled out to the left, it also... This will cause the limiting plate 14 to move, and the limiting plate 14 will cause the fixing ring 15 and the limiting shell 7 to separate. The fixing ring 15 will also disengage from the first limiting groove 2. Then, a silicone strip 8 can be pulled to the left to move. The limiting shell 7 will move through the silicone strip 8. At the same time as the limiting shell 7 is removed from the first limiting groove 2, the limiting shell 7 will also take all the silicone strips 8 out of the second limiting groove 4 together. This achieves the effect of replacing all the silicone strips 8 at once, without having to remove the screws multiple times to replace the silicone strips 8 one by one. After the fixing cover 12 and the roller body 1 are separated, not only can the silicone strips 8 be replaced, but the rotating shaft 9 can also be directly pulled out from the connecting groove 5 to replace the roller body 1 individually, thus reducing the cost of use.
