Description

Technical Field

[0001] This invention relates to the field of brushing machine technology, and more specifically to a single-motor brushing machine device. Background Technology

[0002] During zinc electrolysis, electrolyte, crystals, or impurities adhere to the surface of the zinc plate (cathode plate), requiring brushing to remove these deposits and ensure the smooth progress of subsequent zinc stripping processes and the quality of the zinc product. The brushing machine is the core equipment for this process, using symmetrically arranged brush rollers to brush both sides of the zinc plate. Currently, most brushing machines use a dual-motor drive system, where the brush rollers on both sides of the zinc plate are driven by independent lifting motors. However, in practical applications, the dual-motor solution has the following problems: 1. Asynchronous Lifting: Due to differences in the start-up response time, speed characteristics, and braking delay of the two motors, it is difficult for the brush rollers on both sides to achieve completely synchronized lifting movements. Even with a synchronization control algorithm, inherent physical deviations cannot be eliminated. Asynchrony leads to inconsistent contact heights between the brush rollers and the zinc plate, resulting in uneven force on the zinc plate and even causing it to jam or be damaged. Furthermore, asynchronous lifting directly affects the consistency of the pressure exerted by the brush rollers on the zinc plate surface, resulting in uneven brushing effects on both sides of the zinc plate, affecting the surface cleanliness of the zinc plate, and consequently reducing the yield of subsequent finished products.

[0003] 2. Higher equipment cost and energy consumption: The two independent lifting drive systems (including motors, reducers, controllers and cables) increase the equipment manufacturing cost, and the operation of dual motors also leads to higher power consumption.

[0004] 3. Increased maintenance complexity: Dual-motor systems mean more potential points of failure and more maintenance workload. The synchronous calibration, parameter matching, and daily maintenance of the two motors all require additional manpower. Summary of the Invention

[0005] The purpose of this invention is to provide a single-motor brushing machine device to solve at least one of the above-mentioned problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A single-motor brushing machine device includes a single-motor drive mechanism and a symmetrically arranged brush roller lifting mechanism. The single-motor drive mechanism includes a lifting motor, a first commutator, a drive shaft, and a second commutator. The lifting motor is drivenly connected to the input end of the first commutator, and the output end of the first commutator is connected to the input end of the second commutator through the drive shaft. The brush roller lifting mechanism includes a first chain lift, a first brush roller assembly, a first lifting guide rail assembly, a second chain lift, a second brush roller assembly, and a second lifting guide rail assembly. The input end of the first commutator is connected to the first chain lift, and the first chain lift drives the first brush roller assembly to move up and down along the first lifting guide rail assembly. The output end of the second commutator is connected to the second chain lift, and the second chain lift drives the second brush roller assembly to move up and down along the second lifting guide rail assembly. The area between the first brush roller assembly and the second brush roller assembly is the brushing station.

[0007] Furthermore, both the first lifting guide rail assembly and the second lifting guide rail assembly include a lifting slide and a roller mounting base. The lifting slide includes two side guide rails and an inner side guide rail. The roller mounting base is provided with two side rollers and an inner side roller. The two side rollers are respectively in rolling engagement with the two side guide rails, and the inner side roller is in rolling engagement with the inner side guide rail.

[0008] Furthermore, the input end of the first commutator has a coaxial double-row sprocket, which includes a first sprocket and a second sprocket. The output shaft of the lifting motor is provided with a drive sprocket. The drive sprocket is connected to the first sprocket via a first chain drive, and the second sprocket is connected to the first drive sprocket of the first chain lifting machine via a second chain drive.

[0009] Furthermore, the output end of the second commutator has a third sprocket, which is connected to the second drive sprocket of the second chain elevator via a third chain drive.

[0010] Furthermore, the output end of the first commutator is connected to a first shaft, the input end of the second commutator is connected to a second shaft, and the first shaft and the second shaft are connected by a universal joint coupling. The first shaft, the second shaft, and the universal joint coupling together constitute a drive shaft.

[0011] Furthermore, both the first brush roller assembly and the second brush roller assembly include a brush roller motor, a brush roller swing mechanism, and a brush roller. The brush roller swing mechanism drives the brush roller to swing toward the work station of the board to be brushed, and the brush roller motor drives the brush roller to rotate.

[0012] Furthermore, the brush roller swing mechanism includes a cylinder, a swing arm, and a central shaft. The brush roller is located below the central shaft, and a connecting arm is provided between the brush roller and the central shaft. The cylinder drives the central shaft to rotate through the swing arm, thereby causing the brush roller to swing towards the work station of the board to be brushed with the central shaft as the axis. The brush roller motor is connected to the central shaft through a first transmission belt, and the central shaft and the brush roller are connected through a second transmission belt.

[0013] Furthermore, the brush roller lifting mechanism also includes a water baffle.

[0014] Furthermore, the brush roller lifting mechanism also includes a pulley tensioning device, which is used to adjust the tension of the first transmission belt.

[0015] Furthermore, the brush roller lifting mechanism also includes a water spray pipe.

[0016] The beneficial effects of this invention are as follows: 1. Achieving Absolute Synchronous Lifting of Brush Rollers on Both Sides: A single motor (lifting motor) is used as the sole power source. Power is distributed equally and synchronously to the chain lifting machines on both sides (first chain lifting machine and second chain lifting machine) via two commutators (first commutator and second commutator), eliminating the synchronization error caused by differences in motor characteristics in dual-motor solutions. During zinc plate washing, the first and second brush roller assemblies are positioned at the same height, ensuring uniform force on both sides of the zinc plate and preventing bending or damage due to asynchrony. Furthermore, the consistent brush roller height and uniform force on both sides of the zinc plate result in even washing of both surfaces, leading to consistent surface cleanliness and effective removal of electrolyte crystals and other deposits, providing high-quality cathode plates for subsequent processes.

[0017] 2. Reduced equipment costs and energy consumption: Only one lifting motor and its drive components are required, eliminating the need for a separate motor and controller, thus reducing the overall manufacturing cost. Furthermore, single-motor operation consumes less energy than dual-motor operation, resulting in long-term savings on electricity bills.

[0018] 3. Simplified Control System and Maintenance: Eliminating the need for complex control logic such as dual-motor speed synchronization and position calibration, the control system is simpler and more reliable. The chain jack has a mature and durable structure, and with the lifting guide rail assembly, it facilitates daily inspection and maintenance, reducing equipment downtime.

[0019] 4. Adaptable to frequent start-stop conditions in zinc plate production lines: Zinc plate washing is usually an intermittent process. The single motor drive system has good response consistency when frequently switching between forward and reverse directions. The brush rollers on both sides always move synchronously, avoiding the cumulative synchronization error that may be caused by frequent start-stop of dual motors, thus improving the stability and reliability of equipment operation.

[0022] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the present invention will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0023] Example 1: like Figures 1-2 As shown, this embodiment provides a single-motor brushing machine device, including a single-motor drive mechanism and a symmetrically arranged brush roller lifting mechanism. The single-motor drive mechanism includes a lifting motor 1, a first commutator 2, a drive shaft, and a second commutator 3. The lifting motor 1 is drivenly connected to the input end of the first commutator 2, and the output end of the first commutator 2 is connected to the input end of the second commutator 3 through the drive shaft. The brush roller lifting mechanism includes a first chain lift 4, a first brush roller assembly 5, a first lifting guide rail assembly 6, a second chain lift 7, a second brush roller assembly 8, and a second lifting guide rail assembly 9. The input end of the first commutator 2 is connected to the first chain lift 4, and the first chain lift 4 drives the first brush roller assembly 5 to move up and down along the first lifting guide rail assembly 6. The output end of the second commutator 3 is connected to the second chain lift 7, and the second chain lift 7 drives the second brush roller assembly 8 to move up and down along the second lifting guide rail assembly 9. The area between the first brush roller assembly 5 and the second brush roller assembly 8 is the brushing station 26.

[0024] In this technical solution, the power output of a lifting motor 1 is sent to the input end of a first commutator 2. The first commutator 2 divides the power into two paths: one path is transmitted to the drive shaft via its output end, and the drive shaft then transmits the power to a second commutator 3; the other path is directly driven by the power branched off from the input end of the first commutator 2 (such as a coaxial sprocket). The first chain lifting machine 4 drives the first brush roller assembly 5 to rise and fall along the first lifting guide rail assembly 6. Simultaneously, after receiving the power from the drive shaft, the second commutator 3 drives the second chain lifting machine 7, which in turn drives the second brush roller assembly 8 to rise and fall along the second lifting guide rail assembly 9. Since the first commutator 2 and the second commutator 3 are rigidly connected by the drive shaft, and both chain lifting machines are driven by the same motor, the rising and falling actions of the first brush roller assembly 5 and the second brush roller assembly 8 are completely synchronized in time and stroke. Therefore, this technical solution has the following technical effects: 1. Achieving Absolute Synchronous Lifting of the Two Brush Rollers 25: A single motor (lifting motor 1) is used as the sole power source. Power is distributed equally and synchronously to the chain lifting machines (first chain lifting machine 4 and second chain lifting machine 7) on both sides via two commutators (first commutator 2 and second commutator 3), eliminating the synchronization error caused by differences in motor characteristics in dual-motor schemes. During zinc plate brushing, the brushing height of the first brush roller assembly 5 and the second brush roller assembly 8 is consistent, ensuring uniform force on both sides of the zinc plate and preventing bending or damage due to asynchrony. Furthermore, the consistent brushing height of the first brush roller assembly 5 and the second brush roller assembly 8 ensures uniform force on both sides of the zinc plate, resulting in uniform brushing of both surfaces, consistent surface cleanliness, and effective removal of electrolyte crystals and other adhering substances, providing high-quality cathode plates for subsequent processes.

[0025] 2. Reduced equipment costs and energy consumption: Only one lifting motor 1 and its drive components are required, eliminating the need for a separate motor and controller, thus reducing the overall manufacturing cost. Furthermore, single-motor operation consumes less energy than dual-motor operation, resulting in long-term savings on electricity bills.

[0026] 3. Simplified Control System and Maintenance: Eliminating the need for complex control logic such as dual-motor speed synchronization and position calibration, the control system is simpler and more reliable. The chain jack has a mature and durable structure, and with the lifting guide rail assembly, it facilitates daily inspection and maintenance, reducing equipment downtime.

[0027] 4. Adaptable to frequent start-stop conditions in zinc plate production lines: Zinc plate washing is usually an intermittent process. The single motor drive system has good response consistency when frequently switching between forward and reverse directions. The two brush rollers 25 always move synchronously, avoiding the cumulative synchronization error that may be caused by frequent start-stop of dual motors, thus improving the stability and reliability of equipment operation.

[0028] Example 2: This embodiment is an optimization based on the above embodiment 1.

[0029] The first lifting guide rail assembly 6 and the second lifting guide rail assembly 9 both include a lifting slide 10 and a roller mounting seat 11. The lifting slide 10 includes two side guide rails 10.1 and an inner guide rail 10.2. The roller mounting seat 11 is provided with two side rollers 11.1 and an inner roller 11.2. The two side rollers 11.1 are in rolling engagement with the two side guide rails 10.1 respectively, and the inner roller 11.2 is in rolling engagement with the inner guide rail 10.2.

[0030] By using the rolling contact between rollers and guide rails to replace the traditional sliding contact between sliders and guide rails, friction and wear and lubrication requirements are greatly reduced, thus solving the problem of inconvenient maintenance of the original slider guide rail structure.

[0031] Example 3: This embodiment is an optimization based on the above embodiment 1.

[0032] The input end of the first commutator 2 has a coaxial double-row sprocket, which includes a first sprocket 12 and a second sprocket 13. The output shaft of the lifting motor 1 is provided with a drive sprocket 14. The drive sprocket 14 is connected to the first sprocket 12 through a first chain 15. The second sprocket 13 is connected to the first drive sprocket 16 of the first chain lifting machine 4 through a second chain 17.

[0033] This structure achieves synchronous power splitting between the lifting motor 1 and the first commutator 2 and the first chain lifting machine 4 through coaxial double-row sprockets. It can simultaneously complete power steering and lifting drive without additional transmission components. It has the advantages of compact transmission route, uniform power distribution and high synchronization accuracy, and avoids the problem of asynchronous lifting caused by independent control in traditional dual-motor schemes.

[0034] Example 4: This embodiment is an optimization based on the above embodiment 1.

[0035] The output end of the second commutator 3 has a third sprocket 18, which is connected to the second drive sprocket 19 of the second chain elevator 7 via a third chain 20.

[0036] This structure reliably transmits the output power of the second commutator 3 to the second chain lift 7 through the third sprocket 18 and the third chain 20, so that the first brush roller assembly 5 and the second brush roller assembly 8 are driven synchronously by the same motor through the commutator, thereby ensuring the synchronicity of the lifting and lowering movements of the brush rollers 25 on both sides of the zinc plate and avoiding the problem of asynchronous lifting and lowering in the dual-motor scheme.

[0037] Example 5: This embodiment is an optimization based on the above embodiment 1.

[0038] The output end of the first commutator 2 is connected to the first shaft 21, and the input end of the second commutator 3 is connected to the second shaft 22. The first shaft 21 and the second shaft 22 are connected by a universal joint coupling 23. The first shaft 21, the second shaft 22 and the universal joint coupling 23 together constitute a drive shaft.

[0039] By using a universal joint coupling 23 to connect the first shaft 21 and the second shaft 22 to form a transmission shaft, the installation coaxiality error and angular deviation between the first commutator 2 and the second commutator 3 can be effectively compensated, ensuring that the power can be transmitted smoothly and at the same speed, thereby achieving strict synchronization of the lifting and lowering of the brush rollers 25 on both sides, while reducing the requirements for the machining accuracy of the frame and facilitating installation and maintenance.

[0040] Example 6: This embodiment is an optimization based on the above embodiment 1.

[0041] Both the first brush roller assembly 5 and the second brush roller assembly 8 include a brush roller motor 24, a brush roller swing mechanism, and a brush roller 25. The brush roller swing mechanism drives the brush roller 25 to swing toward the station 26 to be brushed, and the brush roller motor 24 drives the brush roller 25 to rotate.

[0042] This structure achieves decoupled control of the rotation and pressing actions of the brush roller 25 by independently driving the brush roller 24 to rotate and the brush roller oscillation mechanism to oscillate. The brush roller oscillation mechanism can flexibly adjust the oscillation force and angle according to the surface condition of the zinc plate, thereby optimizing the contact and adhesion between the brush roller 25 and the zinc plate and improving the uniformity and adaptability of brushing.

[0043] Example 7: This embodiment is an optimization based on the above embodiment 6.

[0044] The brush roller swing mechanism includes a cylinder 27, a swing arm 28, and a central shaft 29. The brush roller 25 is located below the central shaft 29. A connecting arm 30 is provided between the brush roller 25 and the central shaft 29. The cylinder 27 drives the central shaft 29 to rotate through the swing arm 28, thereby causing the brush roller 25 to swing towards the brushing station 26 with the central shaft 29 as the axis. The brush roller motor 24 is connected to the central shaft 29 through the first transmission belt 31. The central shaft 29 and the brush roller 25 are connected through the second transmission belt 32.

[0045] This structure integrates the rotational and oscillating drives of the brush roller 25 by using the central shaft 29 as both the swing shaft and the drive shaft: the brush roller motor 24 drives the central shaft 29 to rotate via the first drive belt 31, and then drives the brush roller 25 to rotate via the second drive belt 32. At the same time, the cylinder 27 drives the central shaft 29 to rotate via the swing arm 28, causing the brush roller 25 to swing around the central shaft 29 as a whole towards the zinc plate. This design has the advantages of compact structure, short transmission chain, and good motion coordination. In addition, the cylinder 27 drive can provide flexible pressing, avoiding rigid impact damage to the zinc plate.

[0046] Example 8: This embodiment is an optimization based on the above embodiment 1.

[0047] The brush roller lifting mechanism also includes a baffle plate 33. The baffle plate 33 can protect the sprockets and chains inside the chain lift from splashed liquid during the brushing process. It can effectively block splashed liquid and impurities during the brushing process and prevent them from entering the lifting mechanism, thereby reducing the risk of corrosion and contamination of moving parts such as sprockets, guide rails and rollers, and extending the equipment maintenance cycle.

[0048] Example 9: This embodiment is an optimization based on the above embodiment 1.

[0049] The brush roller lifting mechanism also includes a pulley tensioning device 34, which is used to adjust the tension of the first transmission belt 31.

[0050] The pulley tensioning device 34 can adjust the tension of the first transmission belt 31 at any time, effectively preventing belt slippage or loosening, ensuring stable and reliable power transmission between the brush roller motor 24 and the central shaft 29, while extending the service life of the transmission belt and reducing the frequency of manual maintenance.

[0051] Example 10: This embodiment is an optimization based on the above embodiment 1.

[0052] The brush roller lifting mechanism also includes a water spray pipe. This water spray pipe can spray cleaning fluid onto the zinc plate surface and brush roller 25 during the brushing process, promptly rinsing away the adhering substances brushed off, avoiding secondary pollution, and at the same time playing a role in cooling and lubrication, effectively improving the brushing effect and extending the service life of brush roller 25.

[0053] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
