Abstract
Description
Technical Field
[0001] This application relates to the technical field of ovens, and particularly to a heat-resistant drive unit for an oven system applied to carbon paper materials. Background Art
[0002] Coaters are mainly used for the surface coating process production of films, papers, etc. The coater coats a roll of base material with a specific functional glue, coating, ink, etc., and then dries and rewinds it.
[0003] Currently, in the drying process, the drive roller in the oven is used to transfer carbon paper. Between the two ends of the drive roller and the oven, a single bearing connection method is usually adopted for fixation, that is, first a bearing adapted to the shaft diameter size is provided at the end of the drive roller, and then the bearing is connected to the bearing seat through the bearing. Finally, the motor is used as the power source to drive the drive roller to rotate, so as to realize the continuous transfer of carbon paper. However, affected by its material, the drive roller for transferring carbon paper undergoes a change in the surrounding tube structure and expansion under the influence of the high temperature inside the oven, resulting in cracks or being damaged in the bearing, and then the connection stability between the bearing and the drive roller becomes weak, and oil leakage will also occur. Summary of the Invention
[0004] In order to overcome the deficiencies of the prior art in the above background art, this application provides a heat-resistant drive unit for an oven system applied to carbon paper materials, which can maintain good connection stability between the bearing and the drive roller, and at the same time extend the service life of the drive unit, achieving the purpose of reducing production costs.
[0005] A heat-resistant drive unit for an oven system applied to carbon paper materials provided by this application adopts the following technical solutions:
[0006] A heat-resistant drive unit for an oven system applied to carbon paper materials includes a drive roller. One end of the drive roller assembled with one side wall of the oven is the operation end, and one end of the drive roller assembled with the other side wall of the oven is the drive end. Among them, a bearing seat is provided at the operation end of the oven near the drive roller. A first bearing, a second bearing and a third bearing are rotatably provided on the bearing seat. The operation end of the drive roller simultaneously presses against the first bearing and the second bearing. A space for the drive roller to expand and deform is left between the third bearing and the operation end. The cooperation of the first bearing, the second bearing and the third bearing is used to define the rotation stroke of the drive roller.
[0007] By adopting the above technical solution, when the driving roller deforms due to high heat, under the combined action of the first bearing, the second bearing and the third bearing, a space is reserved at the operating end of the driving roller to allow it to expand and deform at high temperatures, thereby effectively reducing the mechanical jamming between the driving roller and the bearing, improving the smoothness and reliability of the equipment operation, reducing the situation where the bearing is damaged due to the thermal expansion of the driving roller, achieving the extension of the service life of the entire transmission unit, helping to reduce production costs. At the same time, the combined use of the three bearings can more accurately limit the rotation stroke of the driving roller, improving the accuracy and operation stability of the overall mechanical equipment.
[0008] Preferably, the driving roller is a metal roller, or a carbon fiber roller, or an electromagnetic induction heating roller, or a coated roller.
[0009] By adopting the above technical solution, the driving roller can be made of metal, carbon fiber, electromagnetic induction heating material or special coating material, enabling the driving roller to adapt to more types of working environments and special requirements.
[0010] Preferably, a mounting seat, a heat conducting member and a jacket are provided at the driving end of the oven close to the driving roller. The jacket is assembled with the driving end of the driving roller. One end of the jacket away from the driving end is rotatably connected to the heat conducting member, and the heat conducting member is arranged on the mounting seat.
[0011] By adopting the above technical solution, under the combined action of the heat conducting member and the jacket, one end of the driving roller is connected to the mounting seat. During this process, the mounting seat provides sufficient support for the driving roller, enabling the driving roller to operate stably. Moreover, the heat conducting member and the jacket can provide good flexibility and adjustability for the driving roller. At the same time, the heat conducting member has good heat conductivity, which can efficiently conduct and dissipate the heat generated when the driving end of the driving roller moves, avoiding the aggravation of the damage of both due to overheating when the power component is directly connected to the driving roller, and helping to extend the service life of the entire transmission unit.
[0012] Preferably, a fourth bearing is arranged between the heat conducting member and the jacket. One end of the jacket away from the driving end extends into the heat conducting member, and the two are connected through the fourth bearing.
[0013] By adopting the above technical solution, the setting of the fourth bearing helps to reduce the friction between the jacket and the heat conducting member, and to a certain extent, can extend the service life of the equipment, thereby reducing the maintenance cost of the equipment. The introduction of the bearing enables the jacket to rotate smoothly in the heat conducting member, ensuring the transmission efficiency and stability of the driving roller.
[0014] Preferably, both the heat conducting member and the jacket are metal parts.
[0015] By adopting the above technical solution, since both the heat-conducting member and the jacket are metal parts, the heat conduction efficiency of the two can be effectively improved, which helps to disperse and transfer the temperature inside the oven, avoiding the aggravation of the damage of both the power member and the transmission roller due to overheating when they are directly connected, and contributing to extending the service life of the entire transmission unit.
[0016] Preferably, a power member is provided on the mounting seat, and the part of the jacket passing through the heat-conducting member is assembled with the power member, and the power member is used to drive the jacket to rotate.
[0017] By adopting the above technical solution, the setting of the power member realizes the automatic rotation of the jacket, thereby driving the transmission roller to rotate, which helps to improve the transfer efficiency of the carbon paper and the operation convenience.
[0018] Preferably, the power member includes a driving sprocket, a driven sprocket, a chain and a driving motor. Among them, the driving motor is fixed on the mounting seat, the driving sprocket is assembled at the output end of the driving motor, the driven sprocket is assembled on the part of the jacket passing through the heat-conducting member, and the chain is simultaneously engaged with the driving sprocket and the driven sprocket.
[0019] By adopting the above technical solution, the transmission mode of the sprocket and the chain helps to improve the transmission stability and reliability of the transmission roller, reduce the failure rate, and the transmission structure of the sprocket and the chain is relatively simple, which is convenient for daily maintenance and replacement. Through the driving motor, the precise control of the rotation of the jacket can be realized to meet the production requirements.
[0020] Preferably, there is at least one fourth bearing.
[0021] By adopting the above technical solution, there is at least one fourth bearing, which makes the relative movement between the jacket and the heat-conducting member more stable, further reduces the friction between the two, and helps to extend the service life of the transmission unit.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. When the transmission roller deforms due to high heat, under the combined action of the first bearing, the second bearing and the third bearing, a space is reserved at the operating end of the transmission roller to allow it to expand and deform at high temperature, thereby effectively reducing the mechanical jamming between the transmission roller and the bearing, improving the smoothness and reliability of the equipment operation, reducing the situation that the bearing is damaged due to the thermal expansion of the transmission roller, achieving the extension of the service life of the entire transmission unit, and helping to reduce the production cost;
[0024] 2. The combined use of the three bearings can more accurately limit the rotation stroke of the transmission roller, improving the accuracy and operation stability of the overall mechanical equipment;
[0025] 3. The heat-conducting member has good heat conductivity, which can efficiently conduct and dissipate the heat generated when the driving end of the driving roller moves, avoiding the accelerated damage of both due to overheating when the power member is directly connected to the driving roller, and helping to extend the service life of the entire driving unit.

[0029] The following will further describe the present application in detail Figure 1-2 with reference to the accompanying drawings.
[0030] An embodiment of the present application discloses a heat-resistant driving unit for an oven system applied to carbon paper materials.
[0031] The driving unit of the present application is applied to the oven 1 of a coater. The entire driving unit has the characteristic of high temperature resistance, and the driving roller 2 generates a small amount of deformation when working in a high temperature environment for a long time.
[0032] Referring to Figure 1 and Figure 2 , a heat-resistant driving unit for an oven system applied to carbon paper materials includes a driving roller 2. One end of the driving roller 2 assembled with a side wall of the oven 1 is the operating end 21, and the other end of the driving roller 2 assembled with the other side wall of the oven 1 is the driving end 22. Among them, a bearing seat 34 is provided at the operating end 21 of the oven 1 close to the driving roller 2. A first bearing (not shown in the figure), a second bearing 32 and a third bearing 33 are rotatably provided on the bearing seat 34, and the three are distributed in a triangle, so that the third bearing 33 is located on the center line of the first bearing and the second bearing 32. The operating end 21 of the driving roller 2 is simultaneously pressed against the first bearing and the second bearing 32, and a space for the driving roller 2 to expand and deform is left between the third bearing 33 and the operating end 21. The cooperation of the first bearing, the second bearing 32 and the third bearing 33 is used to limit the rotation stroke of the driving roller 2.
[0033] In the present application, when the transmission roller 2 is deformed due to high heat, with the cooperation of the first bearing, the second bearing 32 and the third bearing 33, space is reserved at the operating end 21 of the transmission roller 2 to allow it to expand and deform at high temperatures, thereby reducing the mechanical resistance between the transmission roller 2 and the bearing, improving the stability and reliability of the equipment operation, reducing the possibility of bearing damage due to thermal expansion of the transmission roller 2, and achieving the purpose of extending the service life of the entire transmission unit.
[0034] Specifically, the driving roller 2 is a metal roller, or a carbon fiber roller, or an electromagnetic induction heating roller, or a coating roller, so that the driving roller 2 can adapt to more types of working environments and special requirements.
[0035] Reference Figure 1 and Figure 2 The present application does not limit the specific shape of the oven 1, but it is necessary to ensure that the drive roller 2 maintains a horizontal direction when in operation. A mounting seat 41, a heat conductive member 42 and a jacket 43 are provided at the drive end 22 of the oven 1 close to the drive roller 2. The jacket 43 is assembled with the drive end 22 of the drive roller 2. The end of the jacket 43 away from the drive end 22 is rotatably connected to the heat conductive member 42. The heat conductive member 42 is provided on the mounting seat 41.
[0036] Specifically, the heat conductor 42 and the jacket 43 are both metal parts to improve the thermal conductivity of the two. The part where the jacket 43 is assembled with the transmission end 22 of the drive roller 2 is in a cup-shaped structure. The jacket 43 surrounds the transmission end 22. The end of the jacket 43 away from the transmission end 22 is in a circular shaft structure. A fourth bearing 44 is arranged between the heat conductor 42 and the jacket 43. The end of the jacket 43 away from the transmission end 22 extends into the heat conductor 42, and the two are connected by the fourth bearing 44. In addition, there is at least one fourth bearing 44, and multiple fourth bearings 44 are equidistantly and parallelly assembled on the outer wall of the jacket 43, so that the relative movement between the jacket 43 and the heat conductor 42 is smoother, further reducing the friction between the two, which helps to extend the service life of the transmission unit.
[0037] In the present application, the setting of the fourth bearing 44 helps to reduce the friction between the jacket 43 and the heat conductor 42, which can extend the service life of the equipment to a certain extent, thereby reducing the maintenance cost of the equipment. The introduction of the bearing enables the jacket 43 to rotate smoothly in the heat conductor 42, ensuring the transmission efficiency and stability of the transmission roller 2. Under the cooperation of the heat conductor 42 and the jacket 43, one end of the transmission roller 2 is connected to the mounting seat 41. In this process, the mounting seat 41 provides sufficient support for the transmission roller 2, so that the transmission roller 2 can move stably. The heat conductor 42 has good thermal conductivity, which can efficiently conduct and dissipate the heat generated by the transmission end 22 of the transmission roller 2 when it moves, avoiding the damage of both due to overheating when the power member 5 is directly connected to the transmission roller 2, which helps to extend the service life of the entire transmission unit.
[0038] Further, a power component 5 is provided on the mounting seat 41. The part of the jacket 43 passing through the heat conducting member 42 is assembled with the power component 5. The power component 5 is used to drive the jacket 43 to rotate. Among them, the power component 5 includes a driving sprocket 51, a driven sprocket 52, a chain 53 and a driving motor 54. Among them, the driving motor 54 is fixed on the mounting seat 41, the driving sprocket 51 is assembled at the output end of the driving motor 54, the driven sprocket 52 is assembled at the part of the jacket 43 passing through the heat conducting member 42, and the chain 53 is simultaneously meshed with the driving sprocket 51 and the driven sprocket 52.
[0039] Under the action of the driving motor 54, the driving sprocket 51, the driven sprocket 52 and the chain 53 can rotate simultaneously, so as to drive the jacket 43 and the transmission roller 2 to rotate, which helps to improve the transfer efficiency and operation convenience of the carbon paper. In this application, the transmission mode of the sprocket and the chain 53 helps to improve the transmission stability and reliability of the transmission roller 2, reduce the failure rate, and the transmission structure of the sprocket and the chain 53 is relatively simple, which is convenient for daily maintenance and replacement. Through the driving motor 54, precise control of the rotation of the jacket 43 can be realized to meet the production requirements.
[0040] The above are all the preferred embodiments of this application.

Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
