DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0020] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] As attached Figure 1 , Attachment Figure 2 The utility model shows a guide roller for printing and dyeing polyester cloth, which includes a roller body 1, a roller sleeve 2, a gasket 3, a fastener 4 and an external connection 5. The surface of the roller body 1 is processed with a plurality of guide grooves 11 at even intervals along the circumferential direction. The guide grooves 11 extend along the length direction of the roller body 1 and penetrate the roller body 1. The roller body 1 has mounting holes 12 on both side end surfaces. The roller sleeve 2 is sleeved on the roller body 1. The surface of the roller sleeve 2 is formed with a plurality of concave holes 21. The inner side of the roller sleeve 2 has a plurality of convex strips 22 corresponding to the guide grooves 11. The convex strips 22 are embedded in the guide grooves 11 to fix the roller sleeve 2 and the roller body 1 relatively. The gasket 3 is installed at both ends of the roller body 1. The gasket 3 has through holes corresponding to the mounting holes 12. The diameter of the gasket 3 is larger than the outer diameter of the roller sleeve 2, so as to limit the roller sleeve 2 and prevent the roller sleeve 2 from moving in the axial direction. The external connection part 5 is installed on the outside of the gasket cover 3. The external connection part 5 has a connecting shaft 51 coaxial with the roller body 1. A connecting hole 52 is arranged around the connecting shaft 51 and passes through the external connection part 5. The position of the connecting hole 52 corresponds to the through hole. The fastener 4 passes through the external connection part 5 and the gasket cover 3 in turn and is connected with the mounting hole 12, so that the roller body 1, the gasket cover 3 and the external connection part 5 are fixedly connected.

[0022] The concave holes 21 include long holes and round holes. The long holes extend along the length direction of the roller body 1. The long holes and round holes are arranged in rows and staggered on the surface of the roller sleeve 2 to increase the friction between the roller sleeve 2 and the polyester cloth to prevent the cloth from sliding randomly.

[0023] The inside of the roller body 1 is hollowed out, which reduces the weight of the roller body 1, makes the rotation more flexible, and reduces the material cost. Figure 3 As shown, in this embodiment, the roller body 1 includes a cylindrical outer layer 13, the center of the outer layer 13 has a central body 14 extending in the axial direction, and support walls 15 connected to the outer layer 13 are formed at intervals around the central body 14, which reduces the weight of the roller body 1 while ensuring the structural strength of the roller body 1 and preventing deformation. A cavity is formed between the support wall 15 and the outer layer 13, and the end of the cavity close to the gasket 3 has a boss 16 connected to the outer layer 13, and the mounting hole 12 is located on the boss 16, which improves the position of the mounting hole 12 while occupying less volume, making the connection more reliable.

[0024] In this embodiment, the cross section of the guide groove 11 is semicircular, which allows the roller sleeve 2 to slide along the roller body 1 more smoothly during assembly and disassembly, thereby reducing wear on the roller body 1 and extending the service life.

[0025] When the surface of the roller sleeve 2 of the guide roller for printing and dyeing polyester cloth of the utility model is worn and needs to be disassembled and replaced, it is only necessary to remove the fastener 4 at one end to separate the pad cover 3 and the external connection piece 5 from the roller body 1, and then slide the roller sleeve 2 out along the guide groove 11, and then insert the convex strip 22 of the new roller sleeve 2 into the corresponding guide groove 11, and lock it again with the fastener 4, so as to quickly and conveniently complete the replacement of the roller sleeve 2, avoid the scrapping of the guide roller as a whole, and save resources.

[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
