Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a fabric take-up roller. Background Technology

[0002] Fabric take-up rollers are equipment components used in industries such as textiles, printing and dyeing, and coating to wind fabrics into rolls. By neatly winding the finished fabric onto the take-up rollers, subsequent packaging, transportation, and use can be facilitated.

[0003] Currently, fabric take-up rollers typically consist of a roller body and a rubber sleeve mounted on the roller body. The rubber sleeve has a relatively high coefficient of friction, which prevents the fabric from slipping. Furthermore, the rubber sleeve effectively and evenly transfers tension to the fabric, preventing wrinkles or loosening during the take-up process and ensuring uniform take-up tension. However, after prolonged use, the rubber sleeve is prone to wear and deformation. Since the rubber sleeve is usually bonded to the roller body, the connection is tight, making disassembly difficult. Therefore, replacing a damaged rubber sleeve requires specialized tools and is a cumbersome, time-consuming, and labor-intensive process. Utility Model Content

[0004] The purpose of this invention is to provide a fabric take-up roller to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a fabric take-up roller includes a roller body, on which a rubber sleeve is provided. The rubber sleeve includes an inner sleeve and an outer rubber sleeve disposed outside the inner sleeve. A plurality of locking strips are evenly arranged circumferentially on the inner sidewall of the inner sleeve. A plurality of locking grooves for locking the locking strips are evenly opened circumferentially on the sidewall of the roller body. The cross-section of the locking strips and the locking grooves are T-shaped. End caps for clamping the rubber sleeve are detachably installed at both ends of the roller body. The end caps include a cover for abutting against the rubber sleeve. A rotating shaft is connected to the cover. A threaded head is provided on the side of the cover facing away from the rotating shaft. Threaded holes matching the threaded heads are opened at both ends of the roller body.

[0006] As a further feature of this utility model, both ends of the inner sleeve are provided with storage grooves, and a convex ring is provided inside the storage groove. The convex ring can extend or retract into the storage groove, and several through grooves are evenly provided on the side wall of the convex ring in the circumferential direction.

[0007] As a further feature of this invention, an elastic pad is provided inside the storage groove. The elastic pad is connected to a convex ring. When the elastic pad is in its natural state, the convex ring extends out of the storage groove.

[0008] As a further feature of this invention, a sealing gasket is provided on the side of the cover facing away from the rotating shaft.

[0009] As a further feature of this invention, both the inner sleeve and the clip are made of plastic material.

Then, it can be pushed axially in, so that the retaining strips are engaged in the retaining grooves, and the inner sleeve is then fitted onto the roller body. Then, the two end caps are installed at both ends of the roller body in sequence. First, the threaded head is screwed into the threaded hole. Through the threaded connection between the threaded head and the threaded hole, the end cap is connected to the roller body, so that the end cap and the rubber sleeve are firmly in contact, thereby clamping the rubber sleeve between the two end caps and fixing the rubber sleeve. When it is necessary to replace the rubber sleeve, simply unscrew the threaded head from the threaded hole, then remove the two end caps in sequence, and finally pull the inner sleeve axially out, so that the retaining strips are disengaged from the retaining grooves, and the rubber sleeve can be removed for replacement. No tools are required, and the operation is convenient, simple, time-saving and labor-saving. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-5 As shown, a fabric take-up roller includes a roller body 1 made of stainless steel, which has high strength and hardness, is not easily corroded, and has good durability. A rubber sleeve is provided on the roller body 1, the rubber sleeve including an inner sleeve 2 and an outer rubber sleeve 3 disposed outside the inner sleeve 2. A plurality of locking strips 4 are evenly arranged circumferentially on the inner side wall of the inner sleeve 2, and a plurality of locking grooves 5 are evenly opened circumferentially on the side wall of the roller body 1 for locking the locking strips 4. The cross-section of the locking strips 4 and the locking grooves 5 are T-shaped. Clamping rubber sleeves are detachably installed at both ends of the roller body 1. The end cap includes a cover 6 for contacting the rubber sleeve, and a rotating shaft 7 is connected to the cover 6. A threaded head 8 is provided on the side of the cover 6 facing away from the rotating shaft 7, and threaded holes 9 matching the threaded head 8 are provided at both ends of the roller body 1. When installing the rubber sleeve onto the roller body 1, the inner sleeve 2 can be aligned with the roller body 1, so that the retaining strip 4 is aligned with the retaining groove 5 in sequence, and then pushed axially, so that the retaining strip 4 is engaged with the retaining groove 5, and the inner sleeve 2 is fitted onto the roller body 1. Then, the two end caps are installed at both ends of the roller body 1 in sequence, first threading the threaded head 8 into the roller body 1. The threaded head 8 is screwed into the threaded hole 9. Through the threaded connection between the threaded head 8 and the threaded hole 9, the cover 6 is connected to the roller body 1, ensuring a firm contact between the cover 6 and the rubber sleeve. This clamps the rubber sleeve between the two covers, securing it in place. When replacing the rubber sleeve, simply unscrew the threaded head 8 from the threaded hole 9, then remove the two covers one by one, and finally pull the inner sleeve 2 axially out, disengaging the retaining strip 4 from the retaining groove 5. The rubber sleeve can then be removed and replaced without the need for tools, making the operation convenient, simple, and time-saving. The inner sleeve 2 and the retaining strip 4 are both made of plastic material, which has good hardness and toughness, making it easy for the inner sleeve 2 to be inserted and for the retaining strip 4 to be inserted into the retaining groove 5. A sealing gasket 12 is provided on the side of the cover 6 away from the rotating shaft 7. When the end cap is installed on the roller body 1, the sealing gasket 12 will replace the cover 6 to contact the roller body 1. Due to the cooperation and compression between the cover 6 and the roller body 1, the sealing gasket 12 will undergo elastic deformation, thereby sealing the connection gap between the cover 6 and the roller body 1, making the installation of the end cap on the roller body 1 more stable.

[0021] Please see Figure 3 , Figure 4As shown, storage grooves are provided at both ends of the inner sleeve 2, and a protruding ring 10 is provided inside the storage groove. The protruding ring 10 can extend or retract into the storage groove, and several through grooves 11 are evenly provided circumferentially on the side wall of the protruding ring 10. When it is necessary to remove the rubber sleeve from the roller body 1, the protruding ring 10 can be pushed out of the storage groove first, and then the through grooves 11 can be used as the force point to pull outward, thus pulling the rubber sleeve off the roller body 1. The setting of the protruding ring 10 can serve as a force point, making the operation easier and less strenuous. An elastic pad is provided inside the receiving groove. The elastic pad is connected to the convex ring 10. When the elastic pad is in its natural state, the convex ring 10 extends out of the receiving groove. After the end cap is removed, the support of the elastic pad can push the convex ring 10 to naturally extend out of the receiving groove, making it easy to pull out the rubber sleeve. After the end cap is installed on the roller body 1, the compression of the cover 6 can press the convex ring 10 into the receiving groove. The elastic pad can undergo elastic deformation to adapt to the insertion of the convex ring 10, ensuring the normal installation of the end cap.
