Description

Technical Field

[0001] The utility model relates to the technical field of coating equipment, in particular to a transmission mechanism and continuous coating equipment. Background Art

[0002] Continuous single-rod coating equipment can greatly improve the production rhythm of coating operations, but most of the existing continuous single-rod coating equipment use a friction transmission structure to realize the transportation of the rack. However, this method is prone to transmission structure slippage during the transmission process. Since the transportation time of the single-rod rack of the continuous single-rod coating equipment in each chamber is fixed, once the transmission structure slips, it is very easy to cause the rack to be not transported into place, affecting the coating accuracy.

[0003] In addition, since the coating chamber requires a vacuum environment and the drive shaft of the traditional friction transmission structure transmission wheel needs to extend into the chamber, the transmission structure needs to be sealed at multiple positions, which not only increases the difficulty of sealing, but also creates the risk of leakage at the sealing position after long-term use.

[0004] Therefore, there is an urgent need to provide a transmission mechanism and a continuous coating device to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0005] The utility model aims to provide a transmission mechanism and continuous coating equipment, so as to optimize the transmission structure to a certain extent, avoid the problem that the rack is not transported in place due to the slipping of the transmission structure, and affect the coating accuracy and effect.

[0006] The utility model provides a transmission mechanism for the rack transmission of a continuous coating device, comprising a power component, a first transmission component, a second transmission component and a plurality of guide components; the first transmission component is connected to the power component, a plurality of guide components are arranged at intervals along the length direction of the continuous coating device, and the plurality of guide components each include a first meshing member, a guide wheel and a connecting shaft, the guide wheel is arranged on the connecting shaft, the first meshing member is located at one end of the connecting shaft, and one of the first meshing members is connected to the output end of the first transmission component; the second transmission component includes a first transmission rod extending along the length direction of the continuous coating device and a plurality of second meshing members corresponding to the first meshing member, the first meshing member meshes with the second meshing member.

[0007] Among them, the first transmission component includes a driving wheel, a driven wheel, a transmission belt and an output shaft; the driving wheel is connected to the output end of the power component, the driven wheel is connected to one end of the output shaft, and the other end of the output shaft enters the coating chamber of the continuous coating equipment and is connected to the first engaging member in one of the guide components; the transmission belt is connected to the driving wheel and the driven wheel to transmit the power of the power component to the driven wheel.

[0008] Specifically, the driving wheel and the driven wheel are both pulleys or sprockets, and when the driving wheel and the driven wheel are pulleys, the transmission belt is a transmission belt, and when the driving wheel and the driven wheel are sprockets, the transmission belt is a chain.

[0009] There are two guide wheels, and the two guide wheels are arranged oppositely at two ends of the connecting shaft, and the guide wheels are fixedly connected to the connecting shaft.

[0010] Specifically, the guide assembly also includes a first support member and a second support member, the first support member and the second support member both include a support seat and a bearing, the bearing is arranged in the support seat, the two ends of the connecting shaft are respectively connected to the bearing of the first support member and the bearing of the second support member, and the guide wheel is located between the first support member and the second support member.

[0011] Furthermore, the output shaft is located in the middle position of the coating chamber and is connected to the first engaging member in the guide assembly located in the middle position of the coating chamber; the second transmission assembly also includes a second transmission rod and a third engaging member arranged on the second transmission rod and corresponding to the first engaging member; the second transmission rod and the first transmission rod are located on both sides of the output shaft, and the first transmission rod and the transmission rod both extend along the length direction of the continuous coating equipment.

[0012] Furthermore, the first meshing member, the second meshing member and the third meshing member are all bevel gears.

[0013] Compared with the prior art, the transmission mechanism provided by the utility model has the following advantages:

[0014] The transmission mechanism provided by the utility model is used for the rack transmission of continuous coating equipment, and includes a power component, a first transmission component, a second transmission component and a plurality of guide components; the first transmission component is connected to the power component, and the plurality of guide components are arranged at intervals along the length direction of the continuous coating equipment, and the plurality of guide components each include a first meshing member, a guide wheel and a connecting shaft, the guide wheel is arranged on the connecting shaft, the first meshing member is located at one end of the connecting shaft, and one of the first meshing members is connected to the output end of the first transmission component; the second transmission component includes a first transmission rod extending along the length direction of the continuous coating equipment and a plurality of second meshing members corresponding to the first meshing member, and the first meshing member meshes with the second meshing member.

[0015] From this analysis, it can be seen that the power output by the power component can be transmitted through the first transmission component connected to the power component. Since there are multiple guide components in the present application, and the multiple guide components are arranged at intervals along the length direction of the continuous coating equipment, the guide component includes a connecting shaft and a first engaging member, and the first engaging member is connected to the connecting shaft and is located at one end of the connecting shaft.

Therefore, through the engagement of the first engaging part and the second engaging part, when the power component transmits power to the first engaging part connected to the first transmission component through the first transmission component, it can drive the connecting shaft connected to the first engaging part to rotate, and at the same time, through the first engaging part meshing with the second engaging part, it can drive the first transmission rod to rotate, thereby driving the plurality of second engaging parts on the first transmission rod to rotate.

[0017] Correspondingly, since the first engagement member and the second engagement member are correspondingly engaged, the connecting shafts in the plurality of guide assemblies can be driven synchronously, thereby achieving synchronous rotation of the guide wheels and further achieving transmission of the hanger.

[0018] Since the power transmission is achieved through the engagement of the first engaging member and the second engaging member in the present application, the problem of slippage that is prone to occur in the current friction transmission structure can be solved, and the stability of the power transmission can be improved, thereby ensuring the accuracy of the rack transportation to a certain extent and ensuring the coating accuracy and coating effect.

[0036] like Figure 1 Combination Figure 2 As shown, the utility model provides a transmission mechanism, such as Figure 1 Combination Figure 2 As shown, the utility model provides a transmission mechanism for the rack transmission of a continuous coating device, comprising a power component 1, a first transmission assembly, a second transmission assembly and a plurality of guide assemblies; the first transmission assembly is connected to the power component 1, and the plurality of guide assemblies are arranged at intervals along the length direction of the continuous coating device, and the plurality of guide assemblies each include a first meshing member 6, a guide wheel 8 and a connecting shaft 7, the guide wheel 8 is arranged on the connecting shaft 7, the first meshing member 6 is located at one end of the connecting shaft 7, and one of the first meshing members 6 is connected to the output end of the first transmission assembly; the second transmission assembly includes a first transmission rod 11 extending along the length direction of the continuous coating device and a plurality of second meshing members 13 corresponding to the first meshing member 6, and the first meshing member 6 is meshed with the second meshing member 13.

[0037] Compared with the prior art, the transmission mechanism provided by the utility model has the following advantages:

[0038] The transmission mechanism provided by the utility model can transmit the power output by the power component 1 through the first transmission component connected to the power component 1. Since there are multiple guide components in the present application, and the multiple guide components are arranged at intervals along the length direction of the continuous coating equipment, the guide components include a connecting shaft 7 and a first engaging member 6, and the first engaging member 6 is connected to the connecting shaft 7 and is located at one end of the connecting shaft 7. Therefore, by connecting the first engaging member 6 of one of the guide components to the output end of the first transmission component, the rotation of the connecting shaft 7 of the guide component can be achieved.

[0039] The present application further provides a second transmission component, and the second transmission component includes a first transmission rod 11 extending along the length direction of the continuous coating equipment and a plurality of second meshing members 13 corresponding to the first meshing member 6. Therefore, through the meshing of the first meshing member 6 and the second meshing member 13, when the power component 1 transmits power to the first meshing member 6 connected to the first transmission component through the first transmission component, it can drive the connecting shaft 7 connected to the first meshing member 6 to rotate, and at the same time, through the first meshing member 6 meshing with the second meshing member 13, it can drive the first transmission rod 11 to rotate, thereby driving the plurality of second meshing members 13 on the first transmission rod 11 to rotate.

[0040] Correspondingly, since the first engagement member 6 and the second engagement member 13 are correspondingly engaged, the connecting shafts 7 in the plurality of guide assemblies can be driven synchronously, thereby achieving synchronous rotation of the guide wheels 8 and further achieving transmission of the hanger.

[0041] Since the power transmission is achieved through the engagement of the first engaging member 6 and the second engaging member 13 in the present application, the problem of slippage that is prone to occur in the current friction transmission structure can be solved, and the stability of the power transmission can be improved, thereby ensuring the accuracy of the rack transportation to a certain extent and ensuring the coating accuracy and coating effect.

[0042] It can be understood that in this embodiment, the number of the first transmission rods 11 in the present application is one, and they extend along the length direction of the continuous coating equipment, and the output end of the first transmission assembly is connected to the first engaging member 6 of the guide assembly located in the coating chamber 15 near the inlet 1501 or connected to the first engaging member 6 of the guide assembly located in the coating chamber 15 near the outlet 1502, thereby enabling the driving of one first transmission rod 11.

[0043] Accordingly, in this embodiment, a bearing seat needs to be provided at the other end of the first transmission rod 11, and by connecting with the bearing in the bearing seat, the axis of the first transmission rod 11 can be maintained in the horizontal direction and rotate stably.

[0044] Alternatively, if Figure 1 Combination Figure 2 As shown, the first transmission assembly in the present application includes a driving wheel 2, a driven wheel 3, a transmission belt 4 and an output shaft 5; the driving wheel 2 is connected to the output end of the power component 1, the driven wheel 3 is connected to one end of the output shaft 5, and the other end of the output shaft 5 enters the coating chamber 15 of the continuous coating equipment and is connected to the first engaging member 6 in one of the guide assemblies; the transmission belt 4 is connected to the driving wheel 2 and the driven wheel 3 to transmit the power of the power component 1 to the driven wheel 3.

[0045] The purpose of transmitting the power of the driving wheel 2 to the driven wheel 3 can be achieved through the transmission belt 4, and the purpose of transmitting the power of the power component 1 located outside the coating cavity 15 to the coating cavity 15 can be achieved through the output shaft 5 connected to the driven wheel 3. Accordingly, since the power can be introduced only through one output shaft 5 in the present application, the sealing structure can be reduced to the maximum extent.

[0046] It is understandable that, in actual application, a through hole is formed at the position of the coating cavity 15 corresponding to the output shaft 5, and the output end of the output shaft 5 passes through the through hole into the coating cavity 15, and a sealing ring structure is provided in the through hole, so as to ensure the sealing performance in the coating cavity 15 to a certain extent. After a certain period of use, the aged sealing ring can be removed, and since there is only one sealing position, the efficiency of inspection and maintenance can be greatly improved, the operation time can be reduced, and the maintenance cost can be reduced.

[0047] Preferably, if Figure 2 As shown, in the present application, a synchronous connecting rod 501 can also be arranged between the first engaging member 6 connected to the output shaft 5 and the output shaft 5, and a stable connection between the first engaging member 6 and the output shaft 5 can be achieved through the synchronous connecting rod 501, that is, when the connecting inner diameter of the first engaging member 6 is different from the diameter of the output shaft 5, a stable connection between two structures with different diameters can be achieved through the synchronous connecting rod 501.

[0048] Optionally, based on the above structure, the driving wheel 2 and the driven wheel 3 in the present application are both pulleys or sprockets, and when the driving wheel 2 and the driven wheel 3 use pulleys, the transmission belt 4 is a transmission belt, and when the driving wheel 2 and the driven wheel 3 use sprockets, the transmission belt 4 is a chain.

[0049] Preferably, if Figure 1 Combination Figure 2 As shown, the driving wheel 2 and the driven wheel 3 in the present application are belt pulleys, and correspondingly, the transmission belt 4 is a transmission belt.

[0050] Alternatively, if Figure 1 Combination Figure 2 As shown, the number of guide wheels 8 in the present application is two, and the two guide wheels 8 are relatively arranged at two ends of the connecting shaft 7, and the guide wheels 8 are fixedly connected to the connecting shaft 7.

[0051] The two guide wheels 8 arranged opposite to each other at the two ends of the connecting shaft 7 can stably support the hanger and realize the smooth movement of the hanger.

[0052] Optionally, the edge of the guide wheel 8 in the present application can form a limiting protrusion, so that the bracket can be limited by the limiting protrusions of the two guide wheels 8, avoiding the problem of the bracket moving in the axial direction of the connecting shaft 7.

[0053] Alternatively, if Figure 1 Combination Figure 2 As shown, the guide assembly in the present application also includes a first support member 9 and a second support member 10. The first support member 9 and the second support member 10 both include a support seat and a bearing. The bearing is arranged in the support seat, and the two ends of the connecting shaft 7 are respectively connected to the bearing of the first support member 9 and the bearing of the second support member 10, and the guide wheel 8 is located between the first support member 9 and the second support member 10.

[0054] The connecting shaft 7 can be stably supported by the first supporting member 9 and the second supporting member 10 respectively arranged at the two ends of the connecting shaft 7, and the first supporting member 9 and the second supporting member 10 in the present application both include a supporting seat and a bearing, so that the supporting seat can provide an installation position for the bearing, and the relative rotation of the connecting shaft 7 relative to the coating cavity 15 can also be achieved through the bearing.

[0055] Preferably, if Figure 1 Combination Figure 2 As shown, the output shaft 5 in the present application is located in the middle position of the coating chamber 15, and is connected to the first engaging member 6 in the guide assembly located in the middle position of the coating chamber 15; the second transmission assembly also includes a second transmission rod 12 and a third engaging member 14 arranged on the second transmission rod 12 and corresponding to the first engaging member 6; the second transmission rod 12 and the first transmission rod 11 are located on both sides of the output shaft 5, and the first transmission rod 11 and the transmission rod both extend along the length direction of the continuous coating equipment.

[0056] In this manner, the output shaft 5 is located in the middle of the coating chamber 15 . Accordingly, in this embodiment, the second transmission assembly also includes a second transmission rod 12 , that is, in this manner, there are two transmission rods, which are relatively arranged on both sides of the output shaft 5 .

[0057] Compared with the first embodiment, the lengths of the first transmission rod 11 and the second transmission rod 12 in this embodiment are the same, and both are smaller than the length of the first transmission rod 11 in the first embodiment, thereby making the rotation of the first transmission rod 11 more stable and avoiding the problem of the first transmission rod 11 being too long, causing the middle position to bend due to the influence of gravity.

[0058] Correspondingly, in this manner, the second engaging member 13 of the first transmission rod 11 toward one end of the output shaft 5 and the third engaging member 14 of the second transmission rod 12 toward one end of the output shaft 5 are both engaged with the first engaging member 6 on the output shaft 5, thereby being able to simultaneously drive the first transmission rod 11 and the second transmission rod 12 to rotate, thereby being able to realize the rotation of the connecting shaft 7 in the entire guide assembly.

[0059] Preferably, if Figure 1 Combination Figure 2 As shown, in the above embodiment, the first gearing member 6, the second gearing member 13 and the third gearing member 14 in the present application are all bevel gears.

[0060] In addition, the utility model also provides a continuous coating device, including multiple coating units and multiple transmission mechanisms mentioned above; the transmission mechanisms are arranged one by one corresponding to the coating units, and the transmission mechanisms are arranged in the coating units, the multiple coating units are connected in sequence, and the adjacent two coating units are connected.

[0061] The continuous coating equipment using the transmission mechanism provided in the present application can have a better structure for the rack transmission, thereby ensuring the accuracy of the rack in the coating chamber 15, avoiding the problem of rack position error due to transportation error, resulting in reduced coating accuracy and coating effect.

[0062] It is understandable that if Figure 1 As shown, the coating unit in the present application includes a coating chamber 15 and a carrier frame 16 , the coating chamber 15 is disposed on the carrier frame 16 , and the power component 1 of the transmission mechanism is connected to the carrier frame 16 .

[0063] The coating chamber 15 and the power component 1 can be stably supported by the support frame 16 to ensure stable operation of the entire continuous coating equipment.

[0064] Specifically, Figure 1 As shown, an inlet 1501 and an outlet 1502 are respectively formed at both ends of the coating cavity 15 in the present application, and the outlet 1502 of the preceding coating cavity 15 in two adjacent coating cavities 15 is connected to the inlet 1501 of the succeeding coating cavity 15.

[0065] During actual operation, multiple coating units are arranged in sequence. After the rack enters the first coating unit, it enters the coating cavity 15 of each coating unit in sequence along the length direction of the continuous coating equipment to perform coating operations. Accordingly, the rack can be transported through the corresponding inlet 1501 and outlet 1502 of adjacent coating cavities 15.

[0066] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
