According to a second aspect of the present invention, a ceramic roller 10 is disclosed, comprising the above-mentioned steel core 300; referring to fig. 6 and 7, the ceramic roller 10 further includes a ceramic sleeve 100 and two end mechanisms 200, the ceramic sleeve 100 is sleeved outside the cooling section 310, and the inner wall of the ceramic sleeve 100 and the inner wall of the cooling section 310 are arranged at an interval; one of the header mechanisms 200 is coupled to the first mounting section 320 and coupled to one end of the ceramic sheath 100, and the other of the header mechanisms 200 is coupled to the second mounting section 330 and coupled to the other end of the ceramic sheath 100 (see fig. 1).
Through the arrangement of the two end mechanisms 200, the ceramic sleeve 100 is installed outside the steel core 300, the side wall of the steel core 300 and the inner wall of the through hole 111 are arranged at intervals, and a reserved gap is formed between the side wall of the steel core 300 and the inner wall of the through hole 111. When the ceramic sheath 100 works in a high-temperature environment, the ceramic sheath 100 expands in the radial direction, and at this time, since a reserved gap is formed between the side wall of the steel core 300 and the inner wall of the through hole 111, the enlarged part of the ceramic sheath 100 is absorbed by the reserved gap, thereby preventing the ceramic sheath 100 from being crushed due to extrusion between the ceramic sheath 100 and the steel core 300.
In some embodiments, the ceramic piece 100 has a main body portion 110 and connecting portions 120 disposed at both ends of the main body portion 110, and a peripheral surface of the main body portion 110 is used for carrying a product, such as glass 500; the ceramic member 100 is assembled and connected between two end mechanisms 200, the end mechanisms 200 have driving parts 222, and the driving parts 222 are embedded and matched with the connecting parts 120 and are connected in an abutting mode.
Specifically, during product transportation, such as glass 500 transportation, the external driving mechanism drives the end mechanism 200 to rotate. Since the driving portion 222 of the tip mechanism 200 is connected to the connecting portion 120 at the end of the ceramic piece 100 in an abutting manner, a circumferential friction force between the tip mechanism 200 and the ceramic piece 100 is large enough to circumferentially fix the tip mechanism 200 and the ceramic piece 100, so that the tip mechanism 200 drives the ceramic piece 100 to rotate synchronously. And because the glass 500 is placed on the peripheral surface of the ceramic member 100, the glass 500 is normally conveyed during the rotation of the ceramic member 100.
In this application scheme, the cooperation and circumference fixed connection are inlayed with connecting portion 120 of ceramic member 100 to the drive division 222 of end mechanism 200, compare in prior art ceramic member 100 and end mechanism 200 bonding fixed, and this application scheme has avoided ceramic member 100 and end mechanism 200 to appear connecting unstable problem under high temperature environment to guarantee that ceramic member 100 normally rotates with end mechanism 200 is synchronous, and then guarantee that glass 500 is normally carried.
It can be understood that the cooling system of the steel core 300 cools the ceramic part 100, so as to ensure that the ceramic part 100 does not excessively expand due to an excessively high temperature, and further avoid that the ceramic part 100 after the excessive expansion cannot be matched with the driving part 222 of the tip mechanism 200, so that the tip mechanism 200 cannot drive the ceramic part 100 to synchronously rotate.
In some embodiments, referring to fig. 6 to 9, the connecting portion 120 is a cavity disposed at an end of the main body portion 110, and the driving portion 222 is fitted into the cavity, such that after the driving portion 222 is fitted into the cavity, a circumferential surface of the driving portion 222 is connected to an inner circumferential surface of the cavity in a circumferential abutting manner, so that circumferential friction between the tip mechanism 200 and the ceramic element 100 is sufficiently large, and the tip mechanism 200 and the ceramic element 100 rotate synchronously; the connecting portion 120 is a cavity at the end of the main body 110, and the connecting portion 120 is hidden inside the ceramic part 100, so as to ensure that the peripheral surface of the ceramic part 100 has a sufficient distance, thereby preventing the glass 500 from moving onto the end mechanism 200 and being damaged when the glass 500 is conveyed.
In some embodiments, the cavity is tapered. Specifically, the cross-section of the cavity is circular, and the cross-section of the cavity gradually decreases from the socket of the cavity into which the connecting portion 120 or the driving portion 222 is inserted to the bottom of the cavity. Meanwhile, the driving portion 222 or the connecting portion 120 is a cone-shaped body matched with the cavity, and the peripheral surface of the driving portion 222 or the connecting portion 120 is connected with the peripheral surface of the cavity in an abutting manner.
Specifically, by adopting the above structure for the driving portion 222 and the connecting portion 120, after the driving portion 222 is fitted in the connecting portion 120, the abutting force between the driving portion 222 and the connecting portion 120 is the resultant force of the radial force and the axial force of the ceramic part 100, so that if the acting force of the tip mechanism 200 in the axial direction of the ceramic part 100 is large enough, the force between the driving portion 222 and the connecting portion 120 in the radial direction of the ceramic part 100 is large enough, and further, a large circumferential friction force is generated between the driving portion 222 and the connecting portion 120, thereby ensuring the synchronous rotation between the tip mechanism 200 and the ceramic part 100.
It can be understood that, since the end mechanisms 200 are embedded and matched with the ceramic member 100, before the end mechanisms 200 and the ceramic member 100 are not installed, the two end mechanisms 200 and the ceramic member 100 are in a dispersed structure, and therefore, the two end mechanisms 200 and the ceramic member 100 need to be transported to the site for installation, which results in low assembly efficiency of the roller table. Based on the above problem, the ceramic piece 100 and the two end mechanisms 200 are assembled to the steel core 300 through the arrangement of the steel core 300, so that the assembled ceramic roller 10 is subsequently installed on the box 400 of the roller table.
Moreover, in the process of assembling the end mechanism 200 and the ceramic piece 100 to the steel core 300, it can be better ensured that the abutting force between the end mechanism 200 and the ceramic piece 100 along the axial direction of the ceramic piece 100 is relatively large, and further the ceramic piece 100 is tightly abutted between the two end mechanisms 200. Thus, the abutting force between the driving portion 222 of the tip mechanism 200 and the connecting portion 120 of the ceramic part 100 is large enough, and the driving portion 222 and the connecting portion 120 have large enough circumferential friction force, so as to ensure that the tip mechanism 200 and the ceramic part 100 rotate synchronously, and further ensure that the ceramic part 100 normally conveys the glass 500.
In addition, in the rotating process of the steel core 300, the steel core 300 drives the two end mechanisms 200 to rotate at the same time, and the two end mechanisms 200 drive the two ends of the ceramic piece 100 at the same time, so that the ceramic piece 100 and the steel core 300 rotate synchronously, and thus, the end mechanisms 200 and the ceramic piece 100 can be fastened and abutted.

Meanwhile, the elastic element 230 is connected between the base 210 and the movable seat 220, and the elastic element 230 applies an elastic force to the base 210 away from the base 210, so that the movable seat 220 and the ceramic element 100 maintain a fastening and abutting state.
Through the arrangement of the elastic element 230, firstly, under the action of the elastic element 230, the driving part 222 of the elastic element 230 is tightly abutted with the connecting part 120 of the ceramic element 100 by the movable seat 220, so that a large circumferential friction force exists between the driving part 222 of the movable seat 220 and the connecting part 120 of the ceramic element 100, and the movable seat 220 and the ceramic element 100 synchronously rotate; secondly, when the ceramic element 100 expands axially, the movable seat 220 moves close to the base 210, and the elastic element 230 is compressed, so as to absorb the expansion of the ceramic element 100 along the axial direction, and avoid the excessive compression of the movable seat 220 and the end of the ceramic element 100, which results in the damage of the ceramic element 100.
It can be understood that, if the base 210 is directly fixed to the steel core 300, after a large friction damage exists between the connecting portion 120 of the ceramic piece 100 and the driving portion 222 of the tip mechanism 200, the abutting force between the connecting portion 120 of the ceramic piece and the driving portion 222 of the tip mechanism 200 is reduced, so that the tip mechanism 200 and the ceramic piece 100 cannot rotate synchronously; in the present application, after there is a large friction damage between the connecting portion 120 of the ceramic part 100 and the driving portion 222 of the end mechanism 200, at this time, under the action of the elastic member 230, the abutting force between the driving portion 222 of the movable seat 220 and the connecting portion 120 of the ceramic part 100 still remains large enough, so as to ensure that the end mechanism 200 and the ceramic part 100 can rotate synchronously, and further ensure that the ceramic part 100 normally conveys the glass 500.

Furthermore, when the ceramic roller 10 is used for a long time and the abutting force between the driving portion 222 of the movable seat 220 and the connecting portion 120 of the ceramic element 100 is insufficient, at this time, the threaded section 2412 is rotated by the nut 2411, the threaded section 2412 moves toward the ceramic element 100, the stopper 242 moves toward the ceramic element 100, the movable seat 220 moves toward the ceramic element 100 under the action of the disc spring, the connecting portion 120 of the ceramic seat slightly deforms toward the side away from the movable seat 220, and at this time, the abutting between the driving portion 222 of the movable seat 220 and the connecting portion 120 of the ceramic element 100 is more tight.
