The calendering roll 10 and the driving gear 30 are connected together through the coupler 40, so that the calendering roll 10 and the driving gear 30 form a whole, the calendering roll 10 can synchronously rotate along with the rotation of the driving gear 30, and compared with the traditional mode that the driving shaft of a motor is connected with the shaft head of the calendering roll 10 to directly drive the calendering roll 10 to rotate, the connection between the calendering roll 10 and the driving gear 30 is firmer, and the rotation of the calendering roll 10 is more stable.

It can be understood that, the engaging lug 11 of shaft coupling 40 and calendering roller 10 is closely laminated, shaft coupling 40 also closely laminates with drive gear 30, can improve shaft coupling 40 and engaging lug 11 and drive gear 30's fastness of being connected like this, link together shaft coupling 40 with engaging lug 11 and drive gear 30 respectively through the bolt, not only the simple easy operation of connected mode, and this kind of connected mode can be dismantled, just can separate shaft coupling 40 and engaging lug 11 and drive gear 30 and respectively to calendering roller 10 when overhauing the calendering roller device of this application embodiment and maintaining, shaft coupling 40 and drive gear 30 maintain, the maintenance efficiency of calendering roller device has been improved, also make the maintenance operation of calendering roller device more convenient.

It should be noted that, the driving gear 30 in the embodiment of the present application drives the calendering rollers 10 to rotate, so that the rotation of the calendering rollers 10 is more stable, and the transmission precision of the driving gear 30 is higher; wherein, the rotation of drive gear 30 can be through motor drive, specifically say, cooperation drive gear 30 sets up a drive gear, and drive gear meshes with drive gear 30 mutually, set up a motor again, set up a connecting hole of being connected with the drive shaft cooperation of motor at drive gear's center, the drive shaft penetrates just can drive gear rotation in the connecting hole like this, thereby drive gear drives drive gear 30 again and rotates, so that calendering roller 10 rotates along with it, can adjust the rotation direction of the drive shaft of motor according to actual demand, so that the rotation direction of adjustment calendering roller 10.

According to the calendering roller device provided by the embodiment of the application, the calendering roller 10 and the driving gear 30 are connected together through the coupler 40, the calendering roller 10 can synchronously rotate with the driving gear 30 under the driving of the driving gear 30, and the driving gear 30 serves as a transmission device to enable the calendering roller 10 to rotate more stably; and drive gear 30 rotates the setting again on support frame 20, and support frame 20 keeps motionless in the calendering process, so drive gear 30 can the rotation of remain stable, and calendering roller 10 just can be connected with support frame 20 is stable like this for calendering roller 10 is difficult to when rotating to the radial direction production of calendering roller 10 and rocks, and it is more stable to rotate, thereby the glass thickness of calendering can keep evenly, and glass quality is better.

In addition, the interiors of the calendering roll 10 and the support frame 20 are both provided with hollow structures, and the hollow structure inside the calendering roll 10 is communicated with the hollow structure inside the support frame 20, so that the heat exchange liquid can be introduced into the interior of the calendering roll 10 from the hollow port inside the support frame 20, and the temperature of the calendering roll 10 can be reduced; compared with the existing cooling mode that the heat exchange liquid is directly poured into the interior of the calendering roller from the hollow port of the interior of the calendering roller, the cooling mode that the heat exchange liquid flows into the interior of the calendering roller from the second heat exchange channel 200 of the support frame 20 and then flows into the first heat exchange channel 100 to cool the calendering roller 10 is adopted in the embodiment of the application, the support frame 20 is kept still, and the calendering roller 10 is rotated, so that the heat exchange liquid is more convenient to flow into from the port of the second heat exchange channel 200 than the heat exchange liquid is flow into from the port of the first heat exchange channel 100, and the condition that the heat exchange liquid is leaked and spilled is not easy to occur.

In one embodiment, referring to fig. 1, the end surface of the reduction roll 10 is in contact with the end surface of the support frame 20; the coupler 40 abuts against the outer side surface of the reduction roll 10, and the coupler 40 contacts the support frame 20 to rotate the coupler 40 relative to the support frame 20.

It should be noted that the engaging lug 11 disposed on the rolling roll 10 is not flush with the end surface of the rolling roll 10, and the driving gear 30 rotatably disposed on the supporting frame 20 is not flush with the end surface of the supporting frame 20 close to the rolling roll 10, so that the coupling 40 located between the engaging lug 11 and the driving gear 30 is directly opposite to the outer side surface of the rolling roll 10 and the outer side surface of the supporting frame 20, in the embodiment of the present application, the end surface of the rolling roll 10 is in contact with the end surface of the supporting frame 20, and the coupling 40 is disposed to abut against the outer side surface of the rolling roll 10, so that the firmness of connection between the rolling roll 10 and the coupling 40 after the coupling 40 is connected with the engaging lug 11 can be enhanced, the coupling 40 is disposed to be in contact with the supporting frame 20, and the coupling 40 can rotate relative to the supporting frame 20, so that the driving gear 30, the coupling 40 and the rolling roll 10 are rotated synchronously, and a part of the driving gear 30 and the coupling 40 is supported by the supporting frame 20, the shaking generated by the rotation of the driving gear 30 and the rotation of the calendering roller 10 can be greatly reduced, so that the calendering roller 10 can rotate more stably.

The end surface of the support frame 20 close to the calendering roll 10 in the embodiment of the application may have the same shape and size as the end surface of the calendering roll 10, and certainly, the end surface of the support frame 20 close to the calendering roll 10 may have different shapes and sizes from the end surface of the calendering roll 10, and at this time, the inner side surface of the coupler 40 needs to be designed according to the shapes of the outer side surfaces of the calendering roll 10 and the support surface so that the coupler 40 can be abutted against the outer side surface of the calendering roll 10 and contacted with the outer side surface of the support surface; specifically, if the end surface of the support frame 20 close to the calendering roll 10 is the same as the end surface of the calendering roll 10 in shape and size, and is circular, the inner side surface of the coupler 40 may be circular arc, and if the end surface of the support frame 20 close to the calendering roll 10 is the same as the end surface of the calendering roll 10 in shape, but the area of the end surface of the support frame 20 close to the calendering roll 10 is larger than the area of the end surface of the calendering roll 10, the inner side surface of the coupler 40 may be formed by connecting two circular arc surfaces with different inner diameters, and the joint between the two circular arc surfaces may be connected by a smooth curved surface.

In one embodiment, referring to fig. 1, the driving gear 30 is rotatably disposed on the supporting frame 20 through a first bearing 31; the coupling 40 is rotatably disposed on the support frame 20 through a second bearing 41.

It should be noted that the Bearing (Bearing) is a component for fixing and reducing the load friction coefficient during the mechanical transmission. It can also be said that the member for reducing the friction coefficient during power transmission and keeping the center position of the shaft fixed when the other members are moved relative to each other on the shaft. The bearing is a lightweight part in modern mechanical equipment. Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment in the transmission process. The bearings can be classified into rolling bearings and sliding bearings according to the frictional properties of the moving elements.

Specifically, the driving gear 30 in the embodiment of the present application is rotatably disposed on the bracket through the first bearing 31, so that the friction force generated when the driving gear 30 rotates relative to the supporting frame 20 is smaller, the transmission precision of the driving gear 30 is higher, the coupling 40 is rotatably disposed on the supporting frame 20 through the second bearing 41, so that the friction force generated when the coupling 40 rotates relative to the supporting frame 20 is reduced, since the transmission force of the driving gear 30 is transmitted to the calender roll 10 through the coupling 40, the coupler 40 rotates more smoothly to better transmit the transmission force generated by the driving gear 30 to the calendering roll 10, so that the calendering roll 10 can keep synchronous rotation with the driving gear 30, and the phenomenon that the continuous smooth rotation of the calendering roll 10 is influenced by the blocking of the calendering roll 10 in the rotation process can not occur, so that the rotation of the calendering roll 10 is more stable and smooth.

In one embodiment, referring to fig. 1, a bearing seal 42 is disposed between the coupling 40 and the support frame 20, and the bearing seal 42 is connected to the second bearing 41.

It should be noted that the bearing seal ring is a main application of a sealing device in industrial equipment, also called as pressure seal, and is a bearing seal ring based on the principle that the physical principle is a pressure difference principle, that is, the pressure in a seal cavity is different from the environmental pressure by using a sealing structure. The embodiment of the application sets up bearing seal ring 42 between shaft coupling 40 and support frame 20, this bearing seal ring 42 uses with the cooperation of second bearing 41, can effectually block dust and debris and get into the bearing track, make second bearing 41 can realize the smooth rotation of shaft coupling 40 with the cooperation of shaft coupling 40 always, be favorable to the incessant steady rotation of calender roll 10, the phenomenon that the pause blocked can not appear, thereby the glass thickness of calender roll 10 is even, the glass quality is better.

In one of the embodiments, referring to fig. 1, one 200 of the two second heat exchange channels 200 has a heat exchange liquid inlet 201 for inflow of a heat exchange liquid, and the other 200 has a heat exchange liquid outlet 202 for outflow of a heat exchange liquid.

It can be understood that, because the temperature of the glass solution is very high, the temperature of the reduction roll 10 is increased during the process of rolling the glass solution by the reduction roll 10, which easily causes the deformation of the reduction roll 10 and affects the thickness uniformity of the glass rolled by the reduction roll 10, and therefore, the temperature reduction process needs to be performed on the reduction roll 10 during the process of rolling the glass solution by the reduction roll 10. Specifically, the inside first heat exchange passageway 100 that is provided with along calendering roll 10 axial extension and runs through calendering roll 10 of this application embodiment is inside to be set up in support frame 20 and is parallel with first heat exchange passageway 100, and runs through the second heat exchange passageway 200 of support frame 20, because the terminal surface that support frame 20 is close to calendering roll 10 contacts with the terminal surface of calendering roll 10, consequently first heat exchange passageway 100 communicates with second heat exchange passageway 200. The calendering roll 10 device of this application embodiment has two support frames 20, therefore just has two second heat transfer passageways 200, the port of the one end that keeps away from first heat transfer passageway 100 of arbitrary one second heat transfer passageway 200 is regarded as heat-exchanging liquid import 201, the port of the one end that another second heat transfer passageway 200 keeps away from first heat transfer passageway 100 is regarded as heat-exchanging liquid export 202, when the calendering roll device of this application embodiment actually uses, can import heat-exchanging liquid into second heat transfer passageway 200 from heat-exchanging liquid import 201, flow through first heat transfer passageway 100, flow into another second heat transfer passageway 200 again, flow out from heat-exchanging liquid export 202 at last, just so can take away the temperature of calendering roll 10, play the effect of cooling for calendering roll 10.

In one embodiment, referring to fig. 1, a first sealing ring 50 is disposed between the outer side surface of the support frame 20 near one end of the calendering roll 10 and the coupler 40.

It should be noted that, because the end face of the calendering roll 10 is in contact with the end face of the supporting frame 20 near one end of the calendering roll 10, a gap may exist between the calendering roll 10 and the supporting frame 20, so that the heat-exchange liquid input into the first heat-exchange channel 100 and the second heat-exchange channel 200 which are communicated with each other may seep out from the gap, which not only affects the cooling effect of the calendering roll 10, but also may cause the heat-exchange liquid to flow out from the gap and flow onto the glass solution being calendered along the outer surface of the calendering roll 10, which affects the quality of the calendered glass; the first sealing ring 50 is arranged between the outer side surface of one end of the support frame 20 close to the calendering roller 10 and the coupler 40, so that a gap generated between the outer side surface of one end of the support frame 20 close to the calendering roller 10 and the coupler 40 is sealed, and the heat exchange liquid cannot flow out from the gap generated between the outer side surface of one end of the support frame 20 close to the calendering roller 10 and the coupler 40.

In one embodiment, referring to fig. 1, the coupling 40 is tightly attached to the connection lug 11, and a second sealing ring 60 is disposed between the coupling 40 and the connection lug 11.

It should be noted that, because the coupler 40 and the engaging lug 11 are detachably connected together by using a bolt, even if the coupler 40 is tightly attached to the engaging lug 11, along with the length of the using time, a gap with a certain distance may be generated between the coupler 40 and the engaging lug 11, and therefore, the second sealing ring 60 is arranged between the coupler 40 and the engaging lug 11, so that not only can the connection tightness between the coupler 40 and the engaging lug 11 be enhanced, but also the gap which may be generated between the coupler 40 and the engaging lug 11 can be sealed, and thus, the heat exchange liquid cannot flow out from the gap generated between the coupler 40 and the engaging lug 11.

Through the arrangement of the first sealing ring 50 and the second sealing ring 60, the heat exchange liquid in the first heat exchange channel 100 and the second heat exchange channel 200 can be in a closed space, and can not flow out from the first heat exchange channel 100 and the second heat exchange channel 200, so that the cooling effect of the calendering roller 10 is ensured to be kept good all the time.

Specifically, the first seal ring 50 and the second seal ring 60 in the embodiment of the present application may be made of a rubber material, and need to have elasticity and resilience, and have appropriate mechanical strength, including expansion strength, elongation, tear strength, and the like, and stable performance, and are not easy to swell in a medium, small in thermal shrinkage effect (joule effect), easy to machine and form, and capable of maintaining precise size, not corroding a contact surface, not polluting a medium, and being resistant to high temperature, and not easy to deform in a high temperature environment, so that a good sealing effect can be achieved.

In one embodiment, referring to fig. 1, there are two second seal rings 60, and the two second seal rings 60 are spaced apart from each other.

It should be noted that, two second sealing rings 60 are provided, and the two second sealing rings 60 are arranged at intervals, so that the connection firmness between the engaging lug 11 and the coupling 40 can be enhanced, and the connecting surface between the engaging lug 11 and the coupling 40 can be flattened by arranging the two second sealing rings 60, otherwise, only one second sealing ring 60 is easy to connect the engaging lug 11 and the coupling 40 together because of the protrusion existing between the coupling 40 and the engaging lug 11 due to the thickness of the second sealing ring 60, which is not easy to be operated by a worker.

In one of the embodiments, the heat-exchange liquid is optionally cold water or a cooling liquid.

It should be noted that, in the embodiment of the present application, the heat-exchange liquid may be cold water, when the heat-exchange liquid is cold water, the cold water flows in from the heat-exchange liquid inlet 201, the cold water absorbs the temperature of the calender roll 10 in the first heat-exchange channel 100, the cold water is changed into hot water, and the hot water flows out from the heat-exchange liquid outlet 202, at this time, the water needs to continuously flow into the first heat-exchange channel 100 in a circulating manner, specifically, a water tank may be provided, the water tank is respectively communicated with the heat-exchange liquid inlet 201 and the heat-exchange liquid outlet 202, the water in the water tank is pumped into the heat-exchange liquid inlet 201 through a water pump and flows into the first heat-exchange channel 100, then the water after heat exchange flows into the water tank from the heat-exchange liquid outlet 202 to realize water circulation, because the temperature of the water after heat exchange may increase, the temperature of the water in the water tank may also gradually increase, a temperature reducing device may be installed in the water tank, so that the water in the water tank always maintains a constant temperature state, therefore, the temperature of the cold water flowing into the first heat exchange channel 100 from the heat exchange liquid inlet 201 is always consistent, and the cooling effect of the calendering roller 10 can be improved; the water circulation only uses one water tank, so that the water in the water tank can be reused, and the cost is saved.

When the heat exchange liquid is cold water, the cold water can directly flow into the first heat exchange channel 100 and the second heat exchange channel 200, so that the cold water can directly contact with the first heat exchange channel 100, and the cooling effect is better; of course, because the first heat exchange channel 100 direct contact of cold water fish, probably form the incrustation scale on first heat exchange channel 100 surface after long-time the use, influence the cooling effect, and the incrustation scale clearance in first heat exchange channel 100 is more troublesome, staff's work load has been increased, consequently, can consider to arrange a hose in the second heat exchange channel 200 and the first heat exchange channel 100 that communicate each other, be connected the both ends of hose with the water tank respectively, cold water also can take away the heat of calender roll 10 self when flowing through in the hose like this, and still can not form the incrustation scale on first heat exchange pipeline and second heat exchange pipeline surface.

The heat exchange liquid in the embodiment of the present application may also be a cooling liquid, and when the heat exchange liquid is a cooling liquid, the cooling liquid may flow in the first heat exchange channel 100 and the second heat exchange channel 200 in a circulating manner, and heat of the reduction rolls 10 may be taken away by the circulating flow of the cooling liquid, so that the reduction rolls 10 operate at a normal operating temperature. Adopt the coolant liquid can play the anticorrosive effect as heat transfer liquid to can reduce the production of incrustation scale as few as possible, in order to avoid blockking up first heat transfer pipeline and second heat transfer pipeline, influence the cooling effect to calender roll 10.
