Description

Technical Field

[0001] This invention relates to the field of finishing technology for hot-dip galvanizing units, and more specifically, to a cleaning device for finishing machines. Background Technology

[0002] In the field of sheet metal processing, finishing machines are core equipment for ensuring the surface precision of products. During operation, zinc powder, iron filings, and rolling oil residue easily adhere to the roller surface. If these impurities are not removed in time, they will damage the flatness of the roller surface, leading to defects such as scratches and indentations on the subsequently processed sheets, directly affecting the finishing effect and product quality. Therefore, efficient cleaning of finishing machines is an indispensable part of the production process.

[0003] The cleaning system of a finishing mill has a crucial impact on the surface quality of the strip. Incomplete cleaning leads to the accumulation of large amounts of zinc ash and dross on the roller surface, resulting in scrap. Over-cleaning, on the other hand, damages the roller surface, causing varying degrees of roller marks. If not adjusted in time, this can lead to a large number of defective or even scrap products. The nozzle spray angle has a significant impact on the cleaning effect. However, most current finishing mill cleaning systems make it difficult to adjust the nozzle spray angle. This method is prone to localized incomplete or over-cleaning, resulting in inconsistent cleaning results. Once surface defects appear, the only way to improve the cleaning effect is to adjust the spray pressure of the cleaning system, which is difficult to adapt to the rhythm of continuous production. Incomplete or over-cleaning often leads to fluctuations in product quality or even production interruptions.

[0004] Therefore, there is an urgent need for a device to solve the problems in the prior art. Summary of the Invention

[0005] The main objective of this invention is to provide a surface cleaning device that addresses the problems of difficulty in adjusting the spray angle and limited adjustment methods when surface defects occur in existing technologies. When there are many impurities on the roller surface, a combination of reverse spraying and slow speed can be used to enhance the cleaning effect; if there are fewer impurities, a combination of forward spraying and fast speed can be used to reduce damage to the roller surface.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-5 As shown, the present invention provides a cleaning device for a polishing machine, comprising: two sets of support frames 10, disposed on the outlet side of two sets of polishing machine frames, the two sets of support frames 10 being respectively installed on the corresponding polishing machine frames and located at the same horizontal position; a horizontal guide mechanism 20, the horizontal guide mechanism 20 being disposed on the two sets of support frames 10; and an execution mechanism 30, the execution mechanism 30 comprising: a housing 31, the housing 31 being connected to the horizontal guide mechanism 20 and moving horizontally between the two sets of support frames 10 under the action of the horizontal guide mechanism 20; a servo motor 32, the servo motor 32 being disposed within the housing 31; and a gear pair 33, fixed within the housing 31, the input end of the gear pair 33 being connected to the output end of the servo motor 32, the output end of the gear pair 33 being connected to two nozzle assemblies 40 for adjusting the spray angle of the two nozzle assemblies 40 relative to the roller, the nozzle assemblies 40 being connected to an external high-pressure water supply system.

[0021] Specifically, the exit side of the finishing mill stand is the end area where the strip steel is output after being rolled by the finishing mill, and the support frame 10 is a welded structural component. Two sets of support frames 10 are installed on the exit side of the finishing mill stand, providing support and mounting foundation for the horizontal guide mechanism 20. The horizontal guide mechanism 20 is assembled on the two sets of support frames 10, providing horizontal movement guidance for the actuator 30, ensuring that the actuator 30 moves in a straight line between the two sets of support frames 10, and ensuring that the cleaning path is parallel to the rolls.

[0022] The actuator 30 includes a housing 31, a servo motor 32, and a gear pair 33. The housing 31 of the actuator 30 is connected to the horizontal guide mechanism 20, and horizontal movement along the support frame 10 is achieved through the constraint of the guide mechanism. The servo motor 32 and gear pair 33 are integrated inside, serving as the mounting carrier and power transmission hub for the nozzle assembly 40, and carrying out the functions of cleaning action and angle adjustment. The servo motor 32 is located in the housing 31 of the actuator 30 and outputs rotational motion as a power source. By precisely controlling the start, stop, and speed, it drives the gear pair 33 to rotate.

[0023] Gear pair 33 is fixed inside the housing 31 of actuator 30. Its input end is directly connected to the output end of servo motor 32. Through gear meshing, the rotational power of servo motor 32 is transmitted to the output end, controlling the angle adjustment of the two nozzle assemblies 40 to achieve directional adjustment of the relative position of the nozzle and the roll. This optimizes the coverage of the cleaning jet. Specifically, the nozzle assembly 40 is connected to the output end of gear pair 33, receiving the power transmitted by gear pair 33 to adjust the spray angle. Simultaneously, it is connected to an external high-pressure water supply system, directionally spraying high-pressure water onto the roll surface. The impact force of the water flow removes residual zinc slag, oil, and other impurities from the roll surface, completing the online cleaning operation of the finished roll.

[0024] This application uses a horizontal guide mechanism 20 to guide the actuator 30 to move in a direction parallel to the roller, thereby adjusting the horizontal position of the nozzle assembly 40. A servo motor 32 drives the gear pair 33 to rotate, causing the nozzle assembly 40 to change the spray angle, thus adjusting the relative position of the nozzle and the roller. This achieves stable control of the spray angle and distance during cleaning, improving the consistency of the cleaning effect and increasing cleaning efficiency.

[0025] In one possible implementation, the horizontal guide mechanism 20 includes: a drive mechanism 21 mounted on one of the support frames 10; a transmission mechanism 22 whose input end is fixedly connected to the output shaft of the drive mechanism 21; a ball screw 23 horizontally disposed between two support frames 10, with both ends of the screw 23 rotatably passing through the two sets of support frames 10, and one end of the screw connected to the output end of the transmission mechanism 22; a nut of the ball screw 23 connected to the actuator 30; and a linear guide rail 24 disposed parallel above the ball screw 23, with both ends fixed to the two sets of support frames 10; and the actuator 30 slidably connected to the actuator 30 via a slider 25. The drive mechanism 21 drives the transmission mechanism 22 to operate, and the transmission mechanism 22 drives the ball screw 23 to rotate, so that the nut moves horizontally along the screw and drives the actuator 30 to move synchronously. At the same time, the actuator 30 moves along the linear guide rail 24 guided by the slider 25.

[0026] Specifically, the drive mechanism 21 is mounted on a single support frame 10, providing a power source for the horizontal guide mechanism 20. The rotation of the output shaft of the drive mechanism 21 drives the transmission mechanism 22, providing initial power input for subsequent transmission processes. The input end of the transmission mechanism 22 is fixedly connected to the output shaft of the drive mechanism 21, serving as an intermediate link in power transmission. After receiving the rotational power output by the drive mechanism 21, this mechanism adjusts the power parameters through its internal transmission structure, transmitting the appropriate rotational power to the ball screw 23 to ensure that the ball screw 23 receives the required driving force.

[0027] A ball screw 23 is horizontally positioned between two support frames 10, with both ends of the screw rotatably mounted on the support frames 10 via bearings. One end of the screw is connected to the output end of the transmission mechanism 22. When the transmission mechanism 22 drives the screw to rotate, the balls roll between the screw and the nut's helical raceway, converting the rotational motion into linear motion of the nut along the screw axis, thereby driving the actuator 30 connected to the nut to move horizontally. The ball screw 23 is prior art, and its specific structure will not be described in detail here.

[0028] The linear guide rail 24 is mounted parallel to the ball screw 23 and fixed at both ends to two sets of support frames 10. It provides linear movement guidance for the actuator 30 and also connects to the actuator 30 via the slider 25 to bear part of its weight. When the actuator 30 slides along the linear guide rail 24 via the slider 25, the guide rail restricts the actuator 30 to move only along a fixed straight line, while simultaneously sharing the weight of the actuator 30.

[0029] In one possible implementation, the drive mechanism 21 includes: a motor frame 211; a hydraulic motor 212, the hydraulic motor 212 being fixed on the motor frame 211, and the output shaft of the hydraulic motor 212 being fixedly connected to the input end of the transmission mechanism 22.

[0030] Specifically, the drive mechanism 21 consists of a motor frame 211 and a hydraulic motor 212 mounted on the motor frame 211. The output shaft of the hydraulic motor 212 is fixed to the input end of the transmission mechanism 22 by a key connection. The hydraulic motor 212 directly drives the transmission mechanism 22 through its output shaft, providing stable and high-torque initial power to the ball screw 23. The high-torque characteristics of the hydraulic motor 212 can easily drive the ball screw 23 and the actuator 30, adapting to load changes during the cleaning process. The fixed structure of the motor frame 211 enhances the overall rigidity, reduces vibration and offset, and ensures the stability of power transmission. The hydraulic drive method is responsive and easy to adjust, meeting the power requirements under different cleaning conditions. At the same time, it has a compact structure, high reliability, and is suitable for continuous operation of the entire machine.

[0031] In one possible implementation, the transmission mechanism 22 includes: a first input gear 221, which is keyed to the output shaft of the hydraulic motor 212; and a first output gear 222, which meshes with the first input gear 221 and is keyed to one end of the ball screw 23; wherein the hydraulic motor 212 drives the first input gear 221 to rotate, thereby driving the first output gear 222 to rotate via meshing transmission, and thus driving the ball screw 23 to rotate synchronously.

[0032] Specifically, the first output gear 222 is fixed to one end of the ball screw 23 via a key connection; when the first input gear 221 rotates, it serves as the input end of the transmission mechanism 22. When the hydraulic motor 212 drives the first input gear 221 to rotate, power is transmitted to the first output gear 222 through gear meshing, thereby driving the ball screw 23 to rotate synchronously. The gear meshing transmission has a stable transmission ratio, which can precisely control the rotational speed of the ball screw 23 and ensure that the horizontal movement speed of the actuator 30 is uniform; the key connection structure ensures that there is no relative rotation during power transmission, improving transmission reliability; the gear transmission converts the high torque of the hydraulic motor 212 into a rotational driving force suitable for the ball screw 23, resulting in high transmission efficiency and a compact structure.

[0033] In one possible implementation, there are two first output gears 222, which are horizontally symmetrically arranged on both sides of the first input gear 221. Correspondingly, there are two sets of ball screws 23, linear guides 24, and sliders 25. The two sets of linear guides 24 are symmetrically arranged on both sides of the actuator 30, and the two sets of ball screws 23 are symmetrically arranged on both sides of the actuator 30. The two sets of linear guides 24 and the two sets of ball screws 23 are arranged in parallel.

[0034] Specifically, two first output gears 222 are horizontally symmetrically arranged on both sides of the first input gear 221. Each first output gear 222 drives a set of ball screws 23 separately through a key connection. The two sets of ball screws 23 are symmetrically installed on both sides of the actuator 30, and both sets of ball screws 23 are matched with the linear guides 24 arranged parallel to both sides of the actuator 30. Each set of ball screws 23 is equipped with a corresponding linear guide 24. The two ends of the guides are fixed on the support frame 10. The two sides of the actuator 30 are slidably connected to the linear guides 24 on the same side through sliders 25.

[0035] Two sets of symmetrically configured ball screws 23 and linear guides 24 distribute the power output from a single hydraulic motor 212 to two first output gears 222 via a first input gear 221. These gears synchronously drive the ball screws 23 on both sides to rotate, causing the nuts on both sides of the actuator 30 to synchronously move the housing 31 in translation. The linear guides 24 on both sides provide precise guidance for the actuator 30, working in conjunction with the ball screws 23 to constrain the movement path, ensuring that the actuator 30 moves smoothly in a direction parallel to the roll. Simultaneously, the symmetrical force-bearing structure disperses the weight of the actuator 30 and the cleaning reaction force, improving the system's operational stability, transmission efficiency, and load reliability. The two first output gears 222 have the same number of teeth and module, ensuring that they can synchronously drive the corresponding ball screws 23 at the same speed, enabling the actuator 30 to move synchronously on both sides, guaranteeing the smoothness and straightness of horizontal movement.

[0036] In one possible implementation, the first input gear 221 and the first output gear 222 are disposed in the first gearbox 223.

[0037] Specifically, the first gearbox 223 is fixedly connected to the motor frame 211 and the support frame 10 respectively. The first input gear 221 and the two first output gears 222 are set in the first gearbox 223, which can provide a closed protective space for gear transmission, effectively preventing water mist and other impurities in the cleaning environment from entering the gear meshing parts, and preventing the gears from wearing out or jamming due to contamination. The gearbox can also maintain the stability of the internal lubricating oil film, reducing friction loss and noise during gear transmission.

[0038] In one possible implementation, the housing 31 includes: a second gearbox 311, with a slider 25 fixedly connected to the upper part of the second gearbox 311 and a ball screw 23 fixedly connected to the bottom of the second gearbox 311; a protective cover 312, which is fixedly connected to the second gearbox 311; wherein the gear pair 33 is installed in the second gearbox 311, and the servo motor 32 is installed in the protective cover 312.

[0039] Specifically, the second gearbox 311 provides a closed installation space for the gear pair 33, effectively protecting the gear meshing components from water mist and other impurities in the cleaning environment, ensuring gear transmission accuracy and service life; the protective cover 312 isolates the servo motor 32 from the external environment, preventing liquid splashes and dust intrusion, and ensuring stable operation of the motor.

[0040] In one possible implementation, the gear pair 33 includes: a second input gear 331, the gear shaft of which is keyed to the output shaft of the servo motor 32; and two second output gears 332, symmetrically arranged on the upper and lower sides of the second input gear 331 and respectively meshing with the second input gear 331; wherein the gear shaft of the second input gear 331 and the gear shafts of the two second output gears 332 are rotatably fixed on the second gearbox 311, and the gear shafts of the second input gear 331 and the gear shafts of the two second output gears 332 are all parallel to the roll axis.

[0041] Specifically, the gear shaft of the second input gear 331 is fixedly connected to the output shaft of the servo motor 32 via a key. Two second output gears 332 are symmetrically arranged on the upper and lower sides of the second input gear 331 and mesh with it. The gear shafts of both the second input gear 331 and the two second output gears 332 are rotatably fixed to the second gearbox 311 via bearings, and both gear shafts are parallel to the roller axis. The servo motor 32 directly transmits power to the second input gear 331 via a key connection, driving the two second output gears 332 to rotate through gear meshing. Since the two second output gears 332 are symmetrically distributed on the upper and lower sides of the second input gear 331 and mesh with it, when the second input gear 331 rotates, it will drive the two second output gears 332 to rotate in the same direction (for example, when the second input gear 331 rotates clockwise, the upper second output gear 332 and the lower second output gear 332 both rotate counterclockwise; when the second input gear 331 rotates counterclockwise, the upper second output gear 332 and the lower second output gear 332 both rotate clockwise); the gear shaft of each second output gear 332 is fixedly connected to the pipe clamp of the corresponding nozzle 40, with the pipe clamp having a fixed point as the reference point. The fulcrum drives the nozzle 40 to swing synchronously with the rotation of the gear shaft; when the second output gear 332 rotates clockwise, the nozzle 40 rotates clockwise by a certain angle; when the second output gear 332 rotates counterclockwise, the nozzle 40 rotates counterclockwise by a certain angle; the total range of clockwise and counterclockwise rotation of the nozzle 40 constitutes its spray angle adjustment range (usually -15° to +15°). The rotation direction and angle of the second input gear 331 are precisely controlled by the servo motor 33, thereby driving the second output gear 332 and the nozzle 40 to achieve precise angle adjustment, thereby adjusting the spray angle of the nozzle on the surface of the roll.

[0042] When the two nozzle assemblies 40 need to achieve the same rotation angle (for example, the nozzles 42 on both sides are symmetrically adjusted and the length of the nozzles 42 and the corresponding roller diameter are the same), the number of teeth and the module of the two second output gears 332 are the same, ensuring that the gear transmission ratio is consistent when the servo motor 32 is driven, and the nozzle assemblies 40 on both sides deflect synchronously with the same amplitude.

[0043] When the two nozzle assemblies 40 need to achieve different rotation angles (for example, the lengths of the nozzles 42 on both sides are different, or the diameters of the corresponding rollers are significantly different, requiring differentiated adjustment of the spray angle), the number of teeth or the module of the two second output gears 332 are different. By changing the gear transmission ratio, the second output gears 332 on both sides generate different angular velocities under the same input speed, thereby precisely adjusting the deflection angle of the corresponding nozzle assembly 40 to adapt to the cleaning needs of different positions.

[0044] In one possible implementation, the nozzle assembly 40 includes: two sets of pipe clamps 41, the first end of each set of pipe clamps 41 being fixedly sleeved on the gear shaft of a second output gear 332 extending out of the second gearbox 311; and two sets of nozzles 42, each set of nozzles 42 including a nozzle and a delivery pipe, one end of the nozzle being connected to the delivery pipe and the other end being opposite to the roller, the port of the delivery pipe being connected to an external high-pressure water supply system, and the body of the delivery pipe being inserted and fixed in the through hole at the second end of the pipe clamp 41. In this configuration, a set of nozzles 42 corresponds to a roller. The rotation of the second output gear 332 drives the corresponding pipe clamp 41 to swing around its gear shaft axis. The swing of the pipe clamp 41 drives the corresponding nozzle 42 to rotate around the fixed point of the pipe clamp 41 as the fulcrum, so as to adjust the relative angle between the nozzle and the corresponding roller.

[0045] Specifically, the first end of each set of pipe clamps 41 is fixedly sleeved on the gear shaft of a second output gear 332 extending out of the second gearbox 311. Each set of nozzles 42 includes a nozzle and a conveying pipe. The nozzle is opposite to the roller surface of the roll. The port of the conveying pipe is connected to an external high-pressure water supply system. The body of the conveying pipe is inserted and fixed in the through hole at the second end of the pipe clamp 41. Each set of nozzles 42 corresponds to a roll. When the second output gear 332 rotates, it drives the corresponding pipe clamp 41 to swing around its gear shaft axis. The swing of the pipe clamp 41 causes the nozzle 42 to rotate around the fixed point of the pipe clamp 41 as the fulcrum, thereby adjusting the relative angle between the nozzle and the roller surface of the corresponding roll. The rotation of the second output gear 332 drives the pipe clamp 41 to swing, achieving precise adjustment of the nozzle 42 angle. The fixed connection between the pipe clamp 41 and the gear shaft, and the fixed insertion of the nozzle 42 through the through hole of the pipe clamp 41, ensure the stability and structural rigidity of the nozzle 42 during angle adjustment. Each roll has an independently set nozzle 42 and pipe clamp 41, adaptable to differences in roll diameter, nozzle 42 length, etc., achieving differentiated angle adjustment, improving cleaning coverage and effect, while maintaining a compact structure for easy maintenance and adjustment. The spray angle adjustment range is -15° to +15°. The cleaning of the roll surface by the nozzle includes forward spraying and reverse spraying. Forward spraying is when the angle between the nozzle spray direction and the tangent at any point on the roll surface during rotation is acute, while reverse spraying is when this angle is obtuse.

[0046] In one possible implementation, the optical cleaning device further includes: a first encoder 50, installed at the screw end of the ball screw 23, for feedback of the rotational speed of the ball screw; a servo motor 32 integrating a brake and a second encoder, for controlling the spray angle of the nozzle assembly 40 and storing rotation angle information; and a controller, communicatively connected to the servo motor 32, the first encoder 50, and the hydraulic motor 212, respectively, for adjusting the output power of the hydraulic motor 212 based on the rotational speed information fed back by the first encoder 50, controlling the horizontal movement speed of the nozzle assembly 40 by adjusting the rotational speed of the ball screw 23, and simultaneously controlling the spray angle of the nozzle assembly 40 by the rotational angle information fed back by the second encoder.

[0047] Specifically, the whole-machine cleaning device is equipped with a first encoder 50 installed at the end of the ball screw 23. The first encoder 50 feeds back the rotational speed signal of the ball screw 23 to the controller. The controller calculates the moving speed of the actuator by combining the real-time monitored rotational speed information with the pitch parameter of the ball screw 23. Different cleaning effects can be achieved by using the moving speed of the actuator and different nozzle angles. (If there are many impurities on the roller surface, a combination of reverse spraying and slow speed can be used to enhance the cleaning effect; if there are few impurities on the roller surface, a combination of forward spraying and fast speed can be used to reduce damage to the roller surface). The servo motor 32 integrates a brake and a second encoder. The second encoder is an absolute encoder, which can accurately control the spray angle of the nozzle assembly 40 and store the rotation angle information. The brake is a braking device built into the servo motor, used to lock the motor shaft to prevent accidental deviation when the machine stops. The second encoder is a sensor that monitors the motor rotation angle in real time and stores position information, used to accurately control the nozzle spray angle and ensure angle memory after power failure. The servo motor 32 with integrated brake and second encoder is existing technology and will not be described in detail here. The controller is communicatively connected to the servo motor 32, the first encoder 50, and the hydraulic motor 212. Based on the speed information fed back by the first encoder 50, it adjusts the output power of the hydraulic motor 212, thereby regulating the speed of the ball screw 23 to control the horizontal movement speed of the nozzle assembly 40. Simultaneously, it precisely controls the spray angle of the nozzle assembly 40 through the rotation angle information fed back by the second encoder. The closed-loop feedback mechanism adjusts the power of the hydraulic motor 212 in real time to ensure the stability of the ball screw 23 speed, ensuring the uniform horizontal movement speed of the actuator 30 and improving the consistency of the cleaning process. The second encoder integrated in the servo motor 32 accurately records the rotation angle and has a power-off position holding function to prevent the loss of angle information after abnormal power failure, ensuring the accuracy of the nozzle assembly 40 angle adjustment and the repeatability of positioning. The controller integrates multi-sensor data to dynamically coordinate the horizontal movement speed and angle adjustment, achieving precise matching between the cleaning path and the spray direction. At the same time, the brake function can lock the angle of the nozzle 42 when the machine stops to avoid accidental deviation, enhancing the reliability, safety, and intelligence level of the system operation, and adapting to the high-precision cleaning requirements in continuous production.

[0048] The working process of the whole machine cleaning device is as follows: a. Cleaning position adjustment: Start the hydraulic motor 212 of the horizontal guide mechanism 20. The gear pair 33, composed of the first input gear 221 and two first output gears 222, drives the ball screw 23 to rotate, driving the entire actuator 30 to reciprocate linearly along the linear guide rail 24. When the actuator 30 moves horizontally between the support frames 10, the first encoder 50 monitors the rotational speed of the ball screw 23 in real time. The operator inputs the target horizontal movement speed parameter according to the rotational speed value displayed by the controller. The controller adjusts the output power of the hydraulic motor 212 to control the rotational speed of the ball screw 23 to adjust the horizontal movement speed of the actuator 30. When the actuator 30 moves to the end of its stroke, the controller controls the hydraulic motor 212 to reverse through the proximity switches on both sides, driving the ball screw 23 to rotate in the opposite direction and pushing the actuator 30 to move horizontally in the opposite direction, realizing the reciprocating movement of the actuator 30 between the support frames 10. b. Dynamic Angle Adjustment: Based on the required cleaning effect, the operator inputs an angle adjustment command for the nozzle 42. The system automatically starts the servo motor 32 within the actuator 30. Through the gear pair 33 consisting of the second input gear 331 and two second output gears 332, the system synchronously drives the two pipe clamps 41 to swing around their gear shaft axis. The swinging of the pipe clamps 41 drives the corresponding nozzle 42 to rotate, thereby changing the spray angle of the high-pressure water jet relative to the roller surface. If both nozzles 42 need to be adjusted synchronously, the operator confirms that the number of teeth and module of the second output gears 332 on both sides are configured to the same value, and directly inputs the angle command. The nozzles 42 on both sides deflect synchronously through the gear pair 33. If differential adjustment is required, the operator needs to pre-install second output gears 332 with different numbers of teeth or modules (this is a hardware configuration difference, not an adjustment during operation), and then input a unified angle command. The servo motor 32, through the gear pair 33, causes the nozzles 42 on both sides to automatically present different deflection angles according to the difference in the transmission ratio of their respective gears. c. Real-time feedback and control: The first encoder 50 provides real-time feedback on the moving speed of the actuator 30, and the second encoder built into the servo motor 32 provides real-time feedback on the angle of the nozzle assembly 40. The operator inputs adjustment parameters based on the real-time rotation speed and angle data displayed by the controller, and coordinates the horizontal moving speed and nozzle 42 angle adjustment to achieve precise and dynamic adjustment of the cleaning position and spray angle. The spray angle adjustment range of the nozzle 42 is -15° to +15°. The adjustment of the nozzle 42 angle can be performed online without stopping the finishing machine. Different spray angles correspond to different cleaning impact forces and cleaning coverage areas to adapt to the process requirements of different roll materials, surface conditions, or production speeds. The device is interlocked with the unit speed. When the unit malfunctions or stops unexpectedly, the hydraulic motor 212 stops running, the servo motor 32 is de-energized and the nozzle 42 angle is locked by the brake, the first encoder 50 stops monitoring, the system returns to standby state, and when the unit resumes production, the device starts with the state parameters before the shutdown.
