Description

Technical Field

[0001] This utility model relates to the field of textile printing and dyeing, and more specifically, it relates to a rubber roller structure. Background Technology

[0002] As an indispensable key component in textile printing and dyeing production, rubber rollers provide uniform pressure through elastic deformation during processes such as pad dyeing and printing, ensuring that dyes or auxiliaries penetrate the fabric evenly and avoiding color differences or defects.

[0003] During storage, the rubber surface of rubber rollers is easily corroded by ozone due to long-term exposure to air, which leads to surface hardening and reduced elasticity. Therefore, when rubber rollers need to be stored for a long time, people will use plastic film to cover the rubber surface of the rubber roller to reduce contact with air, slow down the hardening rate of the rubber surface, and ensure the life of the rubber surface. However, when people use plastic film to cover rubber rollers, the two ends of the plastic film are raised and do not fit the roller shaft head, making this position easy for air to penetrate.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rubber roller structure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rubber roller structure, including a roller body, the outer peripheral wall of the roller body is covered with a rubber layer, and clamping rings are provided on both sides of the roller body; Both sides of the roller body are provided with annular grooves. One side of the clamping ring is provided with an insert ring for embedding into the annular groove. The inner wall of the annular groove is covered with a flexible layer. The side wall of the roller body is also provided with a sliding groove. A sliding post is fixedly connected to the clamping ring. A compression spring is provided in the sliding groove and sleeved on the sliding post. The compression spring provides the clamping ring with a force to press the roller body. Fasteners are also provided on the clamping ring for fixing the clamping ring to the roller body.

[0007] The present invention is further configured such that: the clamping ring is composed of several arc-shaped rings, and the number of sliding pins and fasteners on the arc-shaped rings is at least one.

[0008] The present invention is further configured such that: the fastener is a fixing screw, the fixing screw includes a nut and a stud, the end of the stud facing away from the nut is provided with a threaded section, the arc-shaped ring is provided with a stepped hole, the side wall of the roller is provided with a threaded hole opposite to the stepped hole, the stepped hole includes a large hole and a small hole that are interconnected, the diameter of the large hole is larger than the major diameter of the threaded section, the diameter of the small hole is smaller than the major diameter of the threaded section, and the maximum static friction between the inner wall of the small hole and the stud is greater than the weight of the fixing screw.

[0009] The present invention is further configured such that a friction pad is provided on the inner wall of the small hole.

[0010] The present invention is further configured such that: the arc-shaped ring is provided with a receiving groove, and a pull ring is rotatably connected in the receiving groove; when the fixing screw is threadedly connected in the threaded hole, one end of the nut abuts against the pull ring.

[0011] The present invention is further configured such that friction ridges are provided on both sides of the roller body.

[0012] In summary, this utility model has the following beneficial effects: Fasteners are used to fix the clamping ring to the roller body. During normal use, the clamping ring is fixed to the side wall of the roller body by the fasteners, so that the clamping ring and the roller body are not prone to vibration during the rotation of the roller body, thus ensuring the stability of the roller body rotation. When the roller body needs to be stored for a long time, the fasteners are loosened from the clamping ring. At this time, the sliding post on the clamping ring can slide along the sliding groove in the opposite direction of the roller body. After the plastic film is wrapped around the rubber layer of the roller body, the two ends of the plastic film are bent towards the sides of the roller body and clamped between the clamping ring and one side of the roller body. By setting the insert ring and the ring groove, one end of the plastic film can be bent in the ring groove, thereby reducing the possibility of surrounding air entering the plastic film.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] A type of rubber roller structure, such as Figure 1 , Figure 2 and Figure 3As shown, the roller body 1 includes a rubber layer 2 covering its outer peripheral wall. Roller shafts are provided on both sides of the roller body 1, and clamping rings are provided on both sides of the roller body 1. The roller shafts are located at the center of the clamping rings. Annular grooves 16 are formed on both sides of the roller body 1. An insert ring 17 is provided on one side of the clamping ring for embedding into the annular groove 16, and the insert ring 17 is located near the outer edge of the clamping ring. A flexible layer 3 covers the inner wall of the annular groove 16. A sliding groove 4 is also formed on the side wall of the roller body 1. A sliding post 5 located within the sliding groove 4 is fixedly connected to the clamping ring. A compression spring 6 is provided within the sliding groove 4 and sleeved outside the sliding post 5. The compression spring 6 provides a force to press the clamping ring against the roller body 1. Fasteners are also provided on the clamping ring to fix the clamping ring to the roller body 1. During normal use, the clamping ring is fixed to the side wall of the roller body 1 by the fasteners, thereby... This design ensures that the clamping ring and roller 1 do not vibrate during rotation, thus guaranteeing the stability of roller 1's rotation. When roller 1 needs to be stored for a long time, the fasteners on the clamping ring are released, allowing the sliding post 5 on the clamping ring to slide along the sliding groove 4 away from roller 1. After the plastic film is wrapped around the adhesive layer 2 of roller 1, both ends of the plastic film are bent toward the sides of roller 1, and the plastic film is clamped between the clamping ring and one side of roller 1. By setting the inserting ring 17 and the annular groove 16, one end of the plastic film can be bent within the annular groove 16, thereby reducing the possibility of surrounding air entering the plastic film. The flexible layer 3 reduces rigid impacts on the plastic film, ensuring its integrity. On the other hand, the flexible layer 3 can deform, making the plastic film fit more tightly with the bottom of the groove.

[0017] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the clamping ring is formed by several arc-shaped rings 7. The number of sliding pins 5 and fasteners on the arc-shaped rings 7 is at least one. In this embodiment, there are two arc-shaped rings 7, but the number of arc-shaped rings 7 protected in this application is not limited to two. By setting multiple arc-shaped rings 7, it is more convenient for people to insert both ends of the plastic film into the arc-shaped rings 7 and one side of the roller body 1, because the area that needs to be inserted each time is smaller. People can insert it in multiple times, and if the insertion effect is not good, people only need to lift the corresponding arc-shaped ring 7. The fastener is a fixing screw, which includes a nut 8 and a stud 9. The stud 9 is provided with a threaded section 10 at the end facing away from the nut 8. The arc-shaped rings 7 are provided with stepped holes, and the side wall of the roller body 1 is provided with threaded holes opposite to the stepped holes. The stepped holes include a large hole 11 and a small hole 12 that are interconnected. The diameter of the large hole 11 is larger than the major diameter of the threaded section 10, and the diameter of the small hole 12 is smaller than the major diameter of the threaded section 10. By screwing the fixing screw into the threaded hole until the nut 8 abuts against one side of the arc-shaped ring 7, the arc-shaped ring 7 is fixed to the roller body 1. When it is necessary to release the restrictive force of the fixing screw on the arc-shaped ring 7, the fixing screw is rotated until the threaded section 10 of the fixing screw is fully inserted into the large hole 11. At this time, the fixing screw is completely separated from the threaded hole, and due to the restrictive effect of the small hole 12, the fixing screw will not separate from the stepped hole. Furthermore, the maximum static friction between the inner wall of the small hole 12 and the stud 9 is greater than the weight of the fixing screw. This arrangement makes it difficult for the fixing screw to move when the arc-shaped ring 7 is lifted. A friction pad 13 is provided on the inner wall of the small hole 12. The friction pad 13 is made of rubber and has several friction patterns. By providing the friction pad 13, the friction between the inner wall of the small hole 12 and the stud 9 is increased, thereby ensuring that the maximum static friction between the inner wall of the small hole 12 and the stud 9 is greater than the weight of the fixing screw.

[0018] like Figure 1 , Figure 2 and Figure 3As shown, the arc-shaped ring 7 has a receiving groove 14, and a pull ring 15 is rotatably connected inside the receiving groove 14. Two rotating holes are formed on the inner wall of the receiving groove 14, and both ends of the pull ring 15 are rotatably connected to the two rotating holes respectively. When the fixing screw is threaded into the threaded hole, one end of the nut 8 abuts against the pull ring 15. In the normal state, the pull ring 15 is housed in the receiving groove 14. When the arc-shaped ring 7 needs to be pulled, the pull ring 15 is flipped, causing it to flip out of the receiving groove 14. At this time, the pull ring 15 serves as the force point for pulling the arc-shaped ring 7, facilitating the application of force. In the normal state, the pull ring 15 is located within the receiving groove 14. Furthermore, when the fixing screw is tightened into the threaded hole, part of the nut 8 coincides with the receiving groove 14. At this time, the nut 8 restricts the pull ring 15, thereby preventing the pull ring 15 from flipping out. When the threaded section 10 is located in the large hole 11, there is sufficient distance between the nut 8 and the arc-shaped ring 7 to allow the pull ring 15 to flip out. Friction ridges are provided on both sides of the roller body 1. The position covered by the friction ridges is close to the outer edge of the roller body 1, and the position of the friction ridges does not coincide with the position covered by the clamping ring. By setting the friction ridges, when the plastic film is attached to the side wall of the roller body 1, the plastic film is less likely to curl up due to its stretching deformation, thereby facilitating the clamping of both ends of the plastic film.

All technical solutions falling within the scope of this utility model's concept are protected.
