[0022] In order to facilitate understanding of the utility model, the utility model will be described more fully below with reference to the drawings. The drawings show the preferred embodiments of the utility model. However, the utility model can be realized in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the utility model more thorough and comprehensive.

[0023] Referring to the drawings Figures 1-7 ​As shown in the embodiment, a furnace roller structure includes a roller bar 1 and two roller sleeves 2 respectively sleeved on both ends of the roller bar 1, wherein each roller sleeve 2 is formed with a sleeve cavity with a side opening and used for inserting and fitting the end of the roller bar 1, the inner diameter of the sleeve cavity is equal to or slightly smaller than the diameter of the end of the roller bar 1, so that the end of the roller bar 1 is inserted into the sleeve cavity in the axial direction, achieving the effect of close fitting or even interference fit, avoiding unnecessary loosening or shaking between the roller bar and the roller sleeve 2, and more facilitating the bearing and rotating action of the roller bar.

[0024] In the embodiment, at least one elastic buckle 3 is fixedly arranged on each roller sleeve 2, wherein the elastic buckle 3 of the embodiment includes an elastic arm 31 and a buckle portion 32 integrally formed at the front end of the elastic arm 31, the tail end of the elastic arm 31 is connected with the roller sleeve 2 through a pre-set bolt, and the buckle portion 32 is a boss structure protruding towards the circumferential surface of the roller sleeve 2. Secondly, the roller surface of the end of the roller bar 1 is formed with at least one clamping groove 11 for elastically clamping the elastic buckle 3, that is, after the end of the roller bar 1 is inserted into the sleeve cavity, the elastic buckle 3 is elastically clamped with the clamping groove 11 of the end of the roller bar 1, achieving the effect of fixation, thereby preventing the roller bar 1 from being separated from the roller sleeve 2 in the axial direction. In addition, the elastic clamping mode can realize the detachable replacement function of the roller bar 1. Only by bending the elastic buckle 3 to make the buckle portion 32 exit the clamping groove 11, the roller bar 1 can be axially pulled out of the roller sleeve 2. Especially when the roller bar 1 is replaced due to reaching the rated wear degree, the disassembly and assembly operation is more convenient and fast.

[0025] In the embodiment, at least one through hole 21 communicating with the sleeve cavity is formed on the outer circumferential surface of the roller sleeve 2, and the buckle portion 32 of the elastic buckle 3 can pass through the through hole 21 and be clamped and fitted with the clamping groove 11 of the end of the roller bar 1, that is, the buckle portion 32 of the elastic buckle 3 is elastically clamped and fitted with the mutually aligned through hole 21 and clamping groove 11, so as to realize the quick assembly operation of the elastic buckle 3, the roller sleeve 2 and the roller bar 1.

[0026] In the embodiment, a pair of elastic buckles 3 are fixedly arranged on each roller sleeve 2 in a diametrically opposite manner, and the same end of the roller bar 1 is formed with two clamping grooves 11 in a diametrically opposite manner. Among them, the same pair of two elastic buckles 3 are respectively and correspondingly clamped and fitted with the two clamping grooves 11 of the same end, and the same pair of elastic buckles 3 are elastically clamped with the end of the roller bar 1, so that the assembly structure between the roller sleeve 2 and the roller bar 1 is more stable and reliable. Secondly, two through holes 21 communicating with the sleeve cavity and arranged in a diametrically opposite manner are formed on the outer circumferential surface of the roller sleeve 2, and the buckle portions 32 of the same pair of two elastic buckles 3 pass through the two through holes 21 and are correspondingly clamped and fitted with the two clamping grooves 11 of the same end.

[0027] In this embodiment, the elastic buckle 3 is integrally formed with a stop portion 33 that abuts against the outer circumferential surface of the roller sleeve 2 located at the outer edge of the through hole 21. By utilizing the abutting effect between the stop portion 33 and the outer circumferential surface of the roller sleeve 2, the clamping portion 32 of the elastic buckle 3 can be effectively prevented from being excessively clamped into the through hole 21 and / or the clamping groove 11, thereby achieving a stop limiting effect and facilitating subsequent external prying disassembly operations.

[0028] In this embodiment, the roller bar 1 can be a hollow structure or a solid structure. Those skilled in the art can adopt a hollow structure or a solid structure of the roller bar 1 according to actual needs, which is not specifically limited here.

[0029] In summary, the furnace roller structure of the present embodiment has the following characteristics:

[0030] 1. Wear resistance and service life: Due to the close fit between the roller bar 1 and the roller sleeve 2, this structure can significantly improve the wear resistance of the furnace roller, reduce additional wear caused by looseness or shaking, and thus prolong the service life of the furnace roller.

[0031] 2. High-efficiency heat conduction: If the roller bar 1 adopts a hollow structure, it not only can reduce the overall weight, but also can serve as an effective heat conduction channel to improve the uniformity of heat distribution in the furnace and enhance the heating efficiency.

[0032] 3. Easy maintenance: Through the design of the elastic buckle 3, the disassembly and assembly of the furnace roller become very simple and fast. When the roller bar 1 needs to be replaced due to wear or damage, the elastic buckle 3 can be simply pried out, and the new roller bar 1 can be easily taken out and replaced. This design greatly reduces the complexity and cost of maintenance.

[0033] 4. Safety: Through the close fit between the elastic buckle 3 and the clamping groove 11, the furnace roller will not accidentally separate axially during operation, ensuring the safety of production.

[0034] 5. Environmental protection: When replacing the roller bar 1, the entire furnace roller does not need to be replaced, only the worn roller bar 1 needs to be replaced, which not only can reduce waste, but also is beneficial to environmental protection.

[0035] In summary, this furnace roller structure has the advantages of strong wear resistance, long service life, easy maintenance, high safety, good flexibility, and environmental protection.
