Description

Technical Field

[0001] The utility model relates to the technical field of plate surface coating protection technology and its supporting equipment, and in particular to a coating roller lifting mechanism used in plate coating equipment. The utility model also relates to a plate coating equipment using the coating roller lifting mechanism. Background Art

[0002] In the current metal material processing industry, especially in the field of aluminum material processing, aluminum alloy sheet materials usually need surface protection.

[0003] At present, for the surface protection treatment of aluminum alloy plates, coating equipment is usually used to coat the surface of aluminum alloy plate sheets. During the process implementation and actual operation, since the thickness of the aluminum alloy plate sheets to be coated ranges from 0.8mm to 250mm, the thickness span is very large, so the opening of the coating roller of the coating equipment needs to be matched and adjusted at any time.

[0004] For double-roller laminating equipment, the opening degree of the laminating roller mentioned above refers to the adapted opening size of the two laminating rollers, that is, the distance between the two laminating rollers; and for single-roller laminating equipment, the opening degree of the laminating roller mentioned here refers to the adapted opening size between the laminating roller and the sheet material bearing surface, that is, the distance between the film roller and the sheet material bearing surface. Generally, the sheet material bearing surface is the table top of the workbench of the laminating equipment.

[0005] In the film-coating equipment structure commonly used in the industry, the functional component used to drive the film-coating roller to rise and fall to adjust the opening degree of the film-coating roller is the lifting mechanism. The existing lifting mechanism generally uses a cylinder with a stroke of more than 300mm as the main action mechanism, and then cooperates with an electromagnetic reversing valve to realize the linkage control of the cylinder.

[0006] Although the above-mentioned conventional lifting mechanism can meet the basic operating requirements of the laminating equipment, the cylinder of the lifting mechanism must move to the maximum stroke each time it operates, resulting in the inconvenience of adjusting the working position and opening degree of the laminating roller when laminating aluminum alloy sheet materials of different thicknesses, and the adjustment accuracy is poor, resulting in poor adaptation between the laminating roller and the aluminum alloy sheet materials, which adversely affects the corresponding laminating processing effect.

[0007] In view of this, how to optimize the position adjustment accuracy and adjustment efficiency of the laminating roller by the lifting mechanism of the sheet laminating equipment to optimize the laminating treatment effect of the sheet is an important technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0008] The purpose of the utility model is to provide a coating roller lifting mechanism, which can accurately and reliably adjust the position of the coating roller, and has a high adjustment efficiency, so that the coating treatment effect of the plate can be correspondingly optimized. Another purpose of the utility model is to provide a plate coating device using the coating roller lifting mechanism.

[0009] In order to solve the above technical problems, the utility model provides a coating roller lifting mechanism, including a cylinder arranged above the coating roller and a main drive assembly capable of driving the cylinder to lift and reciprocate, the extended end of the piston rod of the cylinder is located at the bottom of the cylinder, and the extended end of the piston rod is linked to the coating roller through a vertically arranged extension rod.

[0010] Preferably, the main drive assembly comprises a threaded conduit coaxially sleeved on the outer periphery of the extension rod, and the bottom end of the extension rod extends out of the bottom end of the threaded conduit;

[0011] The main drive assembly also includes a coupling seat arranged at the top end of the threaded conduit, a threaded driving member arranged between the coupling seat and the coating roller, and a driving device capable of driving the threaded driving member to rotate. The coupling seat is respectively linked to the cylinder and the threaded conduit, and the outer wall of the threaded conduit has an external thread that is compatible with the thread of the threaded driving member.

[0012] Preferably, a positioning sleeve is coaxially sleeved on the outer periphery of the threaded conduit, and a guide key adapted to the threaded conduit is protrudingly provided on the inner wall of the positioning sleeve.

[0013] Preferably, the bottom end of the threaded conduit is linked with an end positioning sleeve, the extension rod passes through the end positioning sleeve from top to bottom and extends out of the bottom end of the end positioning sleeve, and the threaded drive is a worm gear arranged in the end positioning sleeve.

[0014] Preferably, a guide copper sleeve coaxially sleeved on the outer periphery of the extension rod is fixedly provided at the bottom of the end positioning sleeve.

[0015] Preferably, the threaded driving member is a threaded guide sleeve coaxially sleeved on the outer periphery of the threaded conduit, and the inner wall of the threaded guide sleeve has an internal thread that matches the external thread of the threaded conduit.

[0016] Preferably, the driving device is a bidirectional servo motor.

[0017] Preferably, a guide nut coaxially aligned with the extension rod and the threaded conduit is provided at the bottom of the coupling seat.

[0018] The utility model also provides a plate film coating device, comprising a frame, on which a film coating roller and a film coating roller lifting mechanism are arranged, and the film coating roller lifting mechanism is the film coating roller lifting mechanism described above.

[0019] Preferably, two of the coating roller lifting mechanisms are connected to the same coating roller, and the two coating roller lifting mechanisms are respectively arranged at two ends of the coating roller.

[0020] Compared with the above background technology, the coating roller lifting mechanism provided by the utility model, when it is assembled, connected and operated, if it is necessary to lift and adjust the position of the coating roller to match the coating operation requirements of plates with different thickness specifications, the main drive component can be used to drive the cylinder to lift as a whole. After the main drive component adjusts the cylinder as a whole to an appropriate position, the cylinder is started to drive the extension rod to perform corresponding extension or retraction operations in the vertical direction, thereby driving the position of the coating roller to be lifted and adjusted synchronously, so as to adjust the position of the coating roller in the vertical direction to a state that can adapt to the size of the plate to be coated, and then the corresponding plate coating processing operation can be performed.

After the overall position of the cylinder is adjusted, the piston rod of the cylinder is used to drive the extension rod to reciprocate and extend relative to the threaded guide tube in the vertical direction, thereby driving the laminating roller to complete the corresponding vertical position fine-tuning to ensure the adaptability of the opening degree of the laminating roller to match the laminating processing requirements of the current size specifications of the plate.

[0035] Please refer to Figure 1 and Figure 2 .

[0036] In a specific embodiment, the coating roller lifting mechanism provided by the utility model includes a cylinder 11 arranged above the coating roller 20 and a main drive assembly capable of driving the cylinder 11 to lift and reciprocate. The extended end of the piston rod of the cylinder 11 is located at the bottom of the cylinder 11, and the extended end of the piston rod is linked to the coating roller 20 via a vertically arranged extension rod 111.

[0037] It is not difficult to understand that during actual assembly, in order to ensure the linkage effect between the cylinder 11 and the piston rod, the piston rod of the cylinder 11 and the extension rod 111 are coaxially assembled in a counter-positioned manner. Generally, if the cylinder body of the cylinder 11 is also a regular columnar structure, the cylinder body of the cylinder 11 and the piston rod are also coaxially arranged, so as to optimize the stress distribution and transmission effect.

[0038] During assembly, connection and operation, if it is necessary to raise and lower the position of the laminating roller 20 in order to match the laminating operation requirements of plates with different thickness specifications, the cylinder 11 can be driven to rise and fall as a whole through the main drive assembly. After the main drive assembly adjusts the cylinder 11 as a whole to the appropriate position, the cylinder 11 can be started to drive the extension rod 111 to perform corresponding extension or retraction operations in the vertical direction, thereby driving the position of the laminating roller 20 to be raised and lowered synchronously, thereby adjusting the position of the laminating roller 20 in the vertical direction to a state that is compatible with the size of the plate to be laminarly processed, and then the corresponding plate laminating operation can be performed.

[0039] After the batch lamination of plates of the current size is completed, if lamination is required for plates of another size, it is only necessary to repeat the adjustment process of the main drive assembly and the cylinder 11 to adjust the laminating roller 20 to a new matching position in order to meet the needs of the next lamination operation.

[0040] The coating roller lifting mechanism forms a two-stage lifting and adjusting mechanism through the coordinated cooperation of the main drive component and the cylinder 11, so that the main drive component is used as an action component for large-scale lifting and adjusting, and the cylinder 11 is used as an action component for fine-tuning the lifting position of the coating roller 20. This greatly improves the lifting and adjusting accuracy of the coating roller 20, makes the vertical position adjustment of the coating roller 20 more precise and controllable, and significantly improves the lifting and adjusting efficiency of the whole coating roller, effectively avoiding the problems of poor adjustment accuracy and low adjustment efficiency caused by relying solely on the large-stroke cylinder 11 to complete the lifting and adjusting operation of the coating roller 20 in the prior art, thereby making the structural adaptability between the plate coating equipment and the plate to be coated stronger, and the corresponding plate coating processing effect is better.

[0041] Specifically, the bottom end of the extension rod 111 and the coating roller 20 can be linked together through a coupling head, and the top end of the extension rod 111 and the piston rod of the cylinder 11 can also be linked together through a coupling head. In practical applications, the coupling head can be a conventional sleeve structure or a cylindrical structure with an assembly end face, or a flange that can be adapted to the corresponding cylinder 11 or coating roller 20 structure. The staff can flexibly select and adjust the specific structural form of the coupling head according to the actual working conditions and component adaptation needs. In principle, any structure that can meet the actual application needs of the coating roller lifting mechanism is acceptable.

[0042] Furthermore, the main drive assembly includes a threaded conduit 12 coaxially sleeved on the outer periphery of the extension rod 111, and the bottom end of the extension rod 111 extends out of the bottom end of the threaded conduit 12; the main drive assembly also includes a coupling seat 121 arranged at the top of the threaded conduit 12, a threaded driving member arranged between the coupling seat 121 and the coating roller 20, and a driving device capable of driving the threaded driving member to rotate, the coupling seat 121 is respectively linked to the cylinder 11 and the threaded conduit 12, and the outer wall of the threaded conduit 12 has an external thread that matches the thread of the threaded driving member.

[0043] When adjusting the position of the laminating roller 20, the driving device is first used to drive the threaded driving member to rotate, so as to utilize the threaded adaption structure between the threaded driving member and the threaded guide tube 12 to drive the threaded guide tube 12 to move synchronously, and then utilize the coupling seat 121 to drive the cylinder 11 to move synchronously with the threaded guide tube 12, so as to achieve the purpose of overall adjustment of the vertical position of the cylinder 11. After the overall position of the cylinder 11 is adjusted, the piston rod of the cylinder 11 is used to drive the extension rod 111 to reciprocate in the vertical direction relative to the threaded guide tube 12, so as to drive the laminating roller 20 to complete the corresponding vertical position fine adjustment, and ensure the adaptability of the opening degree of the laminating roller 20 to match the laminating processing requirements of the current size specifications of the plate.

[0044] Considering the operation requirements and equipment working efficiency under general working conditions, the driving device is preferably a bidirectional servo motor 125, so that the forward or reverse rotation of the bidirectional servo motor 125 can drive the threaded driving member to rotate forward or reverse synchronously, thereby driving the threaded guide tube 12 to complete the rising or falling action through the threaded adapter structure, thereby driving the coating roller 20 to achieve synchronous lifting and lowering adjustment. Of course, in actual applications, simple artificial power mechanisms such as rocker arms can also be used as the actual application type of the driving device to match the equipment cost and operation requirements under different working conditions.

[0045] It should be noted that the matching relationship between the forward and reverse rotation of the bidirectional servo motor 125, the forward and reverse rotation of the threaded drive, and the lifting and lowering of the threaded conduit 12 is not unique, and is only used for illustrative purposes. In other words, in actual applications, the threaded conduit 12 can be lifted by driving the threaded drive forward through the forward rotation of the bidirectional servo motor 125, or the threaded conduit 12 can be lowered by driving the threaded drive forward through the forward rotation of the bidirectional servo motor 125, or the threaded conduit 12 can be lifted by driving the threaded drive reversely through the forward rotation of the bidirectional servo motor 125. In short, the specific linkage adaptation effect between the bidirectional servo motor 125 and the threaded drive and the threaded conduit 12 can be flexibly adjusted and matched according to the actual working conditions. In principle, any effect can be used as long as the lifting and lowering adjustment effect of the coating roller 20 can be guaranteed.

[0046] Furthermore, a positioning sleeve 127 is coaxially sleeved on the outer periphery of the threaded conduit 12, and the positioning sleeve 127 can provide sufficient structural space and reliable structural protection for the threaded conduit 12. A guide key 122 adapted to the threaded conduit 12 is protrudingly provided on the inner wall of the positioning sleeve 127. Generally, a guide groove 112 extending in the vertical direction can be arranged on the outer wall of the threaded conduit 12, and the circumferential relative position between the extension rod 111 and the threaded conduit 12 can be effectively limited by the alignment keyway adaptation between the guide key 122 and the guide groove 112, so as to avoid the circumferential relative rotation between the extension rod 111 and the threaded conduit 12 during the reciprocating telescopic movement, thereby effectively ensuring the tracking property and movement accuracy of the reciprocating telescopic movement of the extension rod 111 driven by the cylinder 11, so that the lifting and lowering adjustment accuracy of the coating roller 20 implemented by the cylinder 11 in cooperation with the extension rod 111 is correspondingly improved, and the adjustment process is more flexible and efficient.

[0047] At the same time, the length of the guide groove 112 can cooperate with the guide key 122 to limit the axial stroke of the extension rod 111, thereby limiting the movement stroke of the piston rod of the cylinder 11, avoiding excessive extension of the piston rod of the cylinder 11 and the extension rod 111, causing the components to loosen or misalign, thereby further ensuring the structural reliability and movement accuracy of the cylinder 11 and the extension rod 111.

[0048] In addition, the bottom end of the threaded conduit 12 is linked with an end positioning sleeve, the extension rod 111 penetrates the end positioning sleeve from top to bottom and extends out of the bottom end of the end positioning sleeve, and the threaded driving member is a worm gear arranged in the end positioning sleeve. The end positioning sleeve can provide reliable structural support and appropriate structural limit for the bottom end of the threaded conduit 12, and the threaded conduit 12 can be driven by the thread adaptation of the worm gear to the threaded conduit 12, so that the reciprocating lifting movement of the threaded conduit 12 has better tracking performance, and the component structure during the action process is more stable and reliable.

[0049] In fact, by utilizing the linkage between the worm wheel and the threaded conduit 12 with external threads, the threaded conduit 12 can be used as a worm that matches the worm wheel, thereby forming a worm gear mechanism with relatively stable transmission, thereby further optimizing the transmission efficiency and structural adaptation effect between the threaded drive component and the threaded conduit 12, thereby further optimizing the overall lifting and lowering efficiency and movement stability of the cylinder 11 and the extension rod 111, and enabling the coating roller lifting mechanism to adjust the lifting and lowering adjustment of the working position of the coating roller 20 and the opening degree and other structural adaptation effects to be adjusted accordingly.

[0050] On this basis, a guide copper sleeve 123 coaxially sleeved on the outer periphery of the extension rod 111 is fixedly provided at the bottom of the end positioning sleeve. The extension rod 111 penetrates and extends out of the guide copper sleeve 123 from top to bottom, so that the guide copper sleeve 123 provides certain structural protection for the main structure of the extension rod 111, and further optimizes the reciprocating telescopic tracking performance of the extension rod 111; at the same time, the guide copper sleeve 123 can prevent the middle part of the end positioning sleeve from having rigid contact or friction with the extension rod 111 at the hole position for the extension rod 111 to penetrate, so as to avoid structural wear at the hole of the extension rod 111 and the end positioning sleeve, so as to make the extension rod 111 and the end positioning sleeve more durable and more adaptable to working conditions.

[0051] Specifically in practical applications, the threaded drive member can also be a threaded guide sleeve 124 coaxially sleeved on the outer periphery of the threaded conduit 12, and the inner wall of the threaded guide sleeve 124 has an internal thread adapted to the external thread of the threaded conduit 12. The threaded guide sleeve 124 has a more compact and regular structure, and its structural adaptability to the threaded conduit 12 is higher, which can further optimize the transmission adaptation effect of the threaded drive member and the threaded conduit 12, and appropriately simplify the number of components of the coating roller lifting mechanism, and make the component structure of the coating roller lifting mechanism more compact, and the coaxial adaptation effect between the various action components is better.

[0052] It should be noted that in actual applications, referring to the adaptation structure of the end positioning sleeve mentioned in the previous embodiments, a guide copper sleeve 123 that can be adapted to the extension rod 111 can also be arranged at the bottom end opening of the middle threaded hole of the threaded guide sleeve 124, so as to avoid rigid contact or structural friction between the extension rod 111 and the threaded guide sleeve 124, and avoid non-working structural wear of the extension rod 111 and the threaded guide sleeve 124, thereby extending the service life of the extension rod 111 and the threaded guide sleeve 124, and optimizing the adaptability of the two to working conditions.

[0053] On the other hand, the bottom of the coupling seat 121 is provided with a guide nut 126 which is coaxially aligned with the extension rod 111 and the threaded conduit 12. The threaded adaptation of the guide nut 126 and the threaded conduit 12 ensures the coaxiality of the threaded conduit 12 and the extension rod 111, and at the same time ensures the alignment effect and assembly strength between the threaded conduit 12 and the coupling seat 121, thereby further optimizing the tracking performance and accuracy of the movement of the extension rod 111 and the piston rod of the cylinder 11 during the reciprocating extension and retraction process, so that the adjustment effect of the coating roller lifting mechanism on the coating roller 20 can be correspondingly optimized.

[0054] In a specific embodiment, a sheet coating device provided in a specific embodiment of the utility model includes a frame, on which a coating roller 20 and a coating roller lifting mechanism are arranged, and the coating roller lifting mechanism is the coating roller lifting mechanism described above. The coating roller lifting mechanism of the sheet coating device can accurately and reliably adjust the position of the coating roller 20, and its adjustment efficiency is high, so that the coating treatment effect of the sheet can be correspondingly optimized.

[0055] In practical applications, no matter one, two or more laminating rollers 20 are provided in the sheet laminating device, two laminating roller lifting mechanisms are connected to the same laminating roller 20, and the two laminating roller lifting mechanisms are respectively arranged at the two ends of the laminating roller 20. Generally, a linkage rod 30 can be provided between the two laminating roller lifting mechanisms arranged on the same laminating roller 20, and the two ends of the linkage rod 30 can be respectively linked to the bottom end of the extension rod 111. In this way, the linkage rod 30 is used to ensure the consistency of the movements between the two laminating roller lifting mechanisms, and to ensure the synchronization and linkage effect of the lifting and lowering adjustment of the two ends of the laminating roller 20.

[0056] In addition, if the plate laminating equipment is set up as follows in actual application Figure 1 The two coating rollers 20 shown in the figure can connect the four coating roller lifting mechanisms arranged at the ends of each coating roller 20 through the linkage rods 30 to form a synchronous lifting system. In addition, considering the equipment cost in actual applications, the main drive component can be integrated into the coating roller lifting mechanism arranged at only one end of one of the coating rollers 20, while the coating roller lifting mechanisms arranged at the ends of the remaining coating rollers 20 only need to be arranged with the cylinder 11 and the corresponding extension rod 111. In this way, the reciprocating motion of a single main drive component can be utilized to cooperate with each linkage rod 30 to realize the lifting position adjustment of the cylinder 11 of multiple coating roller lifting mechanisms, thereby further simplifying the number of components and component structure of the plate laminating equipment, improving its component linkage effect and the position adjustment efficiency of the coating roller 20, and effectively optimizing the position adjustment synchronization and adjustment effect of multiple coating rollers 20.

[0057] In summary, it can be seen that when the coating roller lifting mechanism provided in the utility model is assembled, connected and operated, if the position of the coating roller needs to be raised and lowered to match the coating operation requirements of plates with different thickness specifications, the main drive component can be used to drive the cylinder to lift as a whole. After the main drive component adjusts the cylinder as a whole to an appropriate position, the cylinder is started to drive the extension rod to perform corresponding extension or retraction operations in the vertical direction, thereby driving the position of the coating roller to be raised and lowered synchronously, so as to adjust the position of the coating roller in the vertical direction to a state that can be compatible with the size of the plate to be coated, and then the corresponding plate coating processing operation can be performed. After the batch coating of plates of the current size specification is completed, if it is necessary to perform coating processing on plates of another size specification, it is only necessary to repeat the adjustment process of the main drive component and the cylinder, and the coating roller can be adjusted to a new matching position in linkage, so as to meet the needs of the next coating processing operation. The coating roller lifting mechanism forms a two-level lifting and adjusting mechanism through the coordinated cooperation of the main drive component and the cylinder, thereby utilizing the main drive component as an actuating component for large-scale lifting and adjusting, and the cylinder as an actuating component for fine-tuning the lifting position of the coating roller, thereby greatly improving the lifting and adjusting accuracy of the coating roller, making the vertical position adjustment of the coating roller more precise and controllable, and the overall lifting and adjusting efficiency is also significantly improved, effectively avoiding the problems of poor adjustment accuracy and low adjustment efficiency caused by relying solely on large-stroke cylinders to complete the lifting and adjusting operation of the coating roller in the prior art, thereby making the structural adaptability between the plate coating equipment and the plate to be coated stronger, and the corresponding plate coating processing effect is better.

[0058] In addition, the sheet laminating equipment provided by the utility model uses the above-mentioned laminating roller lifting mechanism, and its laminating roller lifting mechanism can accurately and reliably adjust the position of the laminating roller, and its adjustment efficiency is relatively high, so that the laminating processing effect of the sheet can be correspondingly optimized.

[0059] The above is a detailed introduction to the coating roller lifting mechanism provided by the utility model and the plate coating equipment using the coating roller lifting mechanism. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
