Specifically, the cooling water is delivered from the water inlet delivery channel 3221 to the bottom bracket bearing cooling inner cavity 311, the bottom bracket bearing cooling inner cavity 311 delivers the cooling water to the end of the annular cooling outer cavity 312 far from the first mounting section 320, i.e., the right end of the annular cooling outer cavity 312, so that the cooling water flows from the right end of the annular cooling outer cavity 312 to the left end of the annular cooling outer cavity 312, thereby reducing the temperature of the outside of the steel core 300 and further cooling the ceramic sleeve 100. When the ceramic roller 10 works in a high temperature environment, the steel core 300 can cool the ceramic sleeve 100, so that the end of the ceramic sleeve 100 is prevented from being softened by the adhesive silica gel, normal rotation of the ceramic sleeve 100 is ensured, and products outside the ceramic sleeve 100 can be safely conveyed.
Moreover, the central shaft cooling inner cavity 311 and the annular cooling outer cavity 312 adopt the above structural design, and the water inlet conveying channel 3221 and the water outlet conveying channel 3224 may be designed in the first mounting section 320, so that the water inlet pipeline connected with the water inlet conveying channel 3221 and the water outlet pipeline connected with the water outlet conveying channel 3224 are connected with the first mounting section 320, so that the water inlet pipeline and the water outlet pipeline are conveniently stored (not shown in the figure).

The driving portion 222 of the tip mechanism 200 is in abutting connection with the connecting portion 120 at the end of the ceramic member 100, so that a sufficient circumferential friction force exists between the tip mechanism 200 and the ceramic member 100 to fix the tip mechanism 200 and the ceramic member 100 circumferentially, and the tip mechanism 200 drives the ceramic member 100 to rotate synchronously. 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, drive portion 222 of end mechanism 200 inlays to establish cooperation and circumference fixed connection with connecting portion 120 of ceramic piece 100, compares ceramic piece 100 and end mechanism 200 bonding fixedly among the prior art, and this application scheme has avoided ceramic piece 100 and end mechanism 200 to appear being connected unstable problem under high temperature environment to guarantee that ceramic piece 100 normally rotates in step with end mechanism 200, and then guarantee that glass 500 is normally carried.
It can be appreciated that the cooling system of the steel core 300 cools the ceramic member 100, so as to ensure that the ceramic member 100 cannot be excessively expanded due to the excessively high temperature, and further avoid that the excessively expanded ceramic member 100 cannot be matched with the driving portion 222 of the end mechanism 200, so that the end mechanism 200 cannot drive the ceramic member 100 to rotate synchronously.
In some embodiments, referring to fig. 6 to 9, the connecting portion 120 is a cavity disposed at an end of the main body 110, and the driving portion 222 is in embedded engagement with the cavity, so that after the driving portion 222 is in embedded engagement with the cavity, a circumferential surface of the driving portion 222 is in circumferential abutting connection with an inner circumferential surface of the cavity, so that a circumferential friction force between the tip mechanism 200 and the ceramic piece 100 is sufficiently large, and the tip mechanism 200 and the ceramic piece 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 member 100, so that a long enough distance is ensured on the peripheral surface of the ceramic member 100, and the glass 500 is prevented from moving onto the end mechanism 200, so that the glass 500 is damaged during conveying.
In some embodiments, the cavity is cone-shaped. Specifically, the cross-section of the cavity is circular, and the cross-section of the cavity gradually decreases from its socket into the bottom of the cavity, wherein the socket is configured to allow the connection portion 120 or the driving portion 222 to be inserted into the cavity. Meanwhile, the driving part 222 or the connecting part 120 is a cone matched with the concave cavity, and the peripheral surface of the driving part 222 or the connecting part 120 is in abutting connection with the peripheral surface of the concave cavity.
Specifically, by adopting the above structure for the driving portion 222 and the connecting portion 120, after the driving portion 222 is fitted with the connecting portion 120, the holding 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 member 100, so, if the acting force of the tip mechanism 200 in the axial direction of the ceramic member 100 is sufficiently large, the force between the driving portion 222 and the connecting portion 120 in the radial direction of the ceramic member 100 is sufficiently large, and further, a sufficiently large circumferential friction force is provided between the driving portion 222 and the connecting portion 120, so as to ensure synchronous rotation between the tip mechanism 200 and the ceramic member 100.
It can be appreciated that, because the end mechanism 200 is embedded and matched with the ceramic piece 100, before the end mechanism 200 is not installed with the ceramic piece 100, the two end mechanisms 200 and the ceramic piece 100 are in a dispersed structure, so that the two end mechanisms 200 and the ceramic piece 100 need to be transported to the site for installation, resulting in lower assembly efficiency of the roller table. Based on the above-described problems, by the arrangement of the steel core 300, the ceramic member 100 and the two-end mechanisms 200 are assembled to the steel core 300, so that the assembled ceramic roller 10 is subsequently mounted on the case 400 of the roller table.
In addition, in the process of assembling the end head mechanism 200 and the ceramic member 100 to the steel core 300, the abutting force between the end head mechanism 200 and the ceramic member 100 along the axial direction of the ceramic member 100 can be better ensured, and the ceramic member 100 can be tightly abutted between the two end head mechanisms 200. In this way, the supporting force between the driving portion 222 of the end mechanism 200 and the connecting portion 120 of the ceramic member 100 is large enough, and the circumferential friction force between the driving portion 222 and the connecting portion 120 is large enough, so that the end mechanism 200 and the ceramic member 100 are guaranteed to rotate synchronously, and the ceramic member 100 is guaranteed to convey the glass 500 normally.
In addition, in the process of rotating the steel core 300, the steel core 300 drives the two end mechanisms 200 to rotate simultaneously, and the two end mechanisms 200 drive the two ends of the ceramic piece 100 simultaneously, so that the ceramic piece 100 and the steel core 300 rotate synchronously, and the end mechanisms 200 and the ceramic piece 100 can be fastened and abutted.
In some embodiments, referring to fig. 6 to 9, the tip mechanism 200 includes a base 210, a movable seat 220 and an elastic member 230, the base 210 is screwed to the first mounting section 320, the movable seat 220 is slidably sleeved on the outer wall of the cooling section 310, and an end portion of the movable seat 220 away from the base 210 is a driving portion 222 in embedded engagement with the connecting portion 120. Meanwhile, the elastic member 230 is connected between the base 210 and the movable seat 220, and the elastic member 230 applies an elastic force to the base 210 away from the base 210, so that the movable seat 220 and the ceramic member 100 are kept in a fastened and abutted state.
Through the arrangement of the elastic member 230, firstly, the driving portion 222 of the elastic member 230 is tightly abutted against the connecting portion 120 of the ceramic member 100 under the action of the elastic member 230, so that a large circumferential friction force exists between the driving portion 222 of the movable seat 220 and the connecting portion 120 of the ceramic member 100, and the movable seat 220 and the ceramic member 100 synchronously rotate; secondly, when the ceramic member 100 expands axially, the movable seat 220 moves close to the base 210, and the elastic member 230 is compressed, so as to absorb the expanded portion of the ceramic member 100 along the axial direction, and avoid the excessive extrusion between the movable seat 220 and the end portion of the ceramic member 100, which results in damage to the ceramic member 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 connection portion 120 of the ceramic element 100 and the driving portion 222 of the end mechanism 200, the contact force between the connection portion 120 of the ceramic element and the driving portion 222 of the end mechanism 200 is reduced, so that the end mechanism 200 and the ceramic element 100 cannot rotate synchronously; in this application, after there is a large friction damage between the connection portion 120 of the ceramic piece 100 and the driving portion 222 of the end mechanism 200, at this time, under the action of the elastic member 230, the holding force between the driving portion 222 of the movable seat 220 and the connection portion 120 of the ceramic piece 100 is still large enough, so as to ensure that the end mechanism 200 and the ceramic piece 100 can keep rotating synchronously, and further ensure that the ceramic piece 100 normally conveys the glass 500.
In some embodiments, the tip mechanism 200 further includes a plurality of stop assemblies 240, wherein the stop assemblies 240 are uniformly positioned around the steel core 300.

Specifically, by setting the limiting component 240, the limiting component 240 assembles the base 210, the movable seat 220 and the elastic member 230 together, so that the base 210, the movable seat 220 and the elastic member 230 can be assembled to the first mounting section 320 of the steel core 300 together, and it can be seen that the ceramic roller 10 is convenient to assemble; wherein, by the arrangement of the guide 241, the sliding connection between the base 210 and the movable seat 220 is realized.
When the ceramic roller 10 is used for a long period of time, and the driving portion 222 of the movable seat 220 is not sufficiently abutted against the connecting portion 120 of the ceramic material 100, at this time, the screw segment 2412 is rotated by the nut 2411, the screw segment 2412 is moved toward the ceramic material 100, the stopper 242 is moved toward the ceramic material 100, the movable seat 220 is moved toward the ceramic material 100 by the disc spring, and the connecting portion 120 of the ceramic seat is slightly deformed toward a side away from the movable seat 220, and at this time, the abutment between the driving portion 222 of the movable seat 220 and the connecting portion 120 of the ceramic material 100 is more tightly fixed.
In some embodiments, the stop assembly 240 further includes a latch 243, the latch 243 being in plug connection with the smooth segment 2413; meanwhile, the limiting piece 242 is an annular body, the limiting piece 242 is slidably sleeved on the smooth section 2413, and the bolt 243 is in butt connection with one side, far away from the elastic piece 230, of the limiting piece 242, so that the movable seat 220 is in butt connection between the elastic piece 230 and the limiting piece 242, and the end head mechanism 200 is convenient to assemble and disassemble.
