Description

Technical Field

[0001] This utility model belongs to the technical field of cold material spraying control device, specifically a cold material spraying flow and pressure control device. Background Technology

[0002] Cold material spraying technology is widely used in construction, machinery, and chemical industries for surface protection and coating preparation due to its advantages such as not requiring high-temperature heating and energy saving and environmental protection. During cold material spraying, the flow rate and pressure stability of the spraying material directly affect the coating thickness uniformity, adhesion, and surface smoothness, and are key factors determining the spraying quality. A search revealed that patent application number 201922073676.4 discloses a novel lithium battery separator coating device and its usage method. The device includes an M-side coating assembly, an N-side coating assembly, a turntable, a feeding system, a return system, a return trough, a cooling system, a filter, a control system, a linkage adjustment device, an oven assembly, a tension adjustment device, a separator, and a liquid supply pump. The feeding device consists of a feeding pump and a flow meter module, integrating the feeding system into one unit. The feeding tank has a stirring function to prevent slurry sedimentation, and the stirring rod is controlled by a motor. The M-side and N-side coating assemblies achieve speed linkage control. The oven assembly can simultaneously dry both sides of the separator. This invention has advantages such as convenient operation, good coating effect, high work efficiency, and cost savings.

[0003] Based on the aforementioned existing technologies, it is known that existing cold material spraying equipment typically uses simple valves to manually adjust the flow and pressure, or uses a variable frequency motor to adjust the speed of the delivery pump to achieve preliminary control. However, these methods have the following drawbacks: their control accuracy is low, manual adjustment relies on the experience of the operators, and it is difficult to make accurate adjustments in real time according to the spraying conditions.

[0027] In another embodiment of this utility model, please refer to Figures 2 to 4 The first pulley 201, the transmission belt 2011, and the second pulley 2012 together form a transmission structure. The drive mechanism includes a mounting frame 3 and a mounting baffle 301. The mounting frame 3 is fixedly installed on the top of the outer wall of the feed pipe 1011, and the mounting baffle 301 is fixedly installed on the top of the mounting frame 3.

[0028] In another embodiment of this utility model, please refer to Figures 3 to 5 The drive mechanism also includes a servo motor 3011, a drive gear 3012, and a driven gear 3013. The servo motor 3011 is fixedly mounted on one side of the mounting baffle 301. The drive gear 3012 is fixedly mounted on the outer wall of the output shaft of the servo motor 3011. The driven gear 3013 is coaxially mounted on the top of the second pulley 2012. The driven gear 3013 meshes with the drive gear 3012 for transmission. By adopting a structure in which the servo motor 3011 is fixedly mounted on one side of the mounting baffle 3011, the drive gear 3012 is fixedly mounted on the outer wall of the output shaft of the servo motor 3011, and the driven gear 3013 is coaxially mounted on the top of the second pulley 2012 and meshes with the drive gear 3012 for transmission, the function of using the servo motor 3011 to provide precise driving force and driving the two control valve plates 2 to precisely and synchronously adjust through gear meshing and pulley transmission is realized, thereby improving the accuracy of flow and pressure control.

[0029] Before the device is put into use, the pipeline installation must be completed. During installation, it is necessary to ensure that the drive belt 2011, the first pulley 201, and the second pulley 2012 are in a vertical state (i.e., perpendicular to the ground). Then, through the connecting flange 1013 in the connecting mechanism, the output pipeline of the external air pump is connected to the air supply pipe 101, and the output pipeline of the external cold material storage and conveying equipment is connected to the material supply pipe 1011. The structural design of the connecting flange 1013 can ensure the sealing and stability of the connection between the external pipeline and the device, and avoid leakage during the airflow and cold material conveying process. At the same time, the air supply pipe 101 and the material supply pipe 1011 are symmetrically arranged on the outside of the spray pipe 1, which lays the foundation for the uniform convergence of the subsequent airflow and cold material in the spray pipe 1. When the device needs to be started for cold material spraying, the external air pump and cold material conveying equipment are first turned on. The airflow generated by the external air pump is conveyed into the spray pipe 1 along the air supply pipe 101, and the cold material output by the external cold material conveying equipment is conveyed into the spray pipe 1 along the material supply pipe 1011. During this process, the one-way valve 1012 installed on the outer wall of the air supply pipe 101 and the material supply pipe 1011 will play a role, allowing only the airflow from the external air pump to the spray pipe 1 and the cold material from the external cold material equipment to the spray pipe 1, preventing the backflow of airflow or cold material due to pressure fluctuations, and ensuring the unidirectionality and stability of the airflow and cold material conveying path. Then, the servo motor 3011 in the drive mechanism is started. After the servo motor 3011 is powered on, its output shaft starts to rotate, driving the drive gear 3012 fixed on the outer wall of the output shaft to rotate synchronously. Since the drive gear 3012 is in a meshing state with the driven gear 3013 coaxially mounted on the top of the second pulley 2012, when the drive gear 3012 rotates, it will drive the driven gear 3013 to rotate through tooth surface transmission, thereby causing the second pulley 2012 coaxial with the driven gear 3013 to rotate accordingly. When the second pulley 2012 rotates, the transmission belt 2011 mounted on its outer side will move due to friction. The transmission belt 2011 is also sleeved on the outer side of the first pulley 201, thus driving the first pulley 201 to rotate synchronously. The first pulley 201 is coaxially fixed with the control valve plate 2 set on the inner wall of the air supply pipe 101, and the second pulley 2012 is coaxially fixed with the control valve plate 2 set on the inner wall of the feed pipe 1011, so that the two control valve plates 2 rotate synchronously under the action of pulley transmission. When the control valve plate 2 rotates within the air supply pipe 101 and the material supply pipe 1011, it changes the size of the flow channel formed between itself and the inner wall of the pipe: when the control valve plate 2 rotates to a small angle with the pipe axis, the cross-section of the flow channel increases, and the flow rate and pressure of the air in the air supply pipe 101 increase accordingly, as does the flow rate of the cold material in the material supply pipe 101; when the control valve plate 2 rotates to a large angle with the pipe axis, the cross-section of the flow channel decreases, and the flow rate and pressure of the air and the flow rate of the cold material decrease accordingly, thereby achieving precise regulation of the flow rate and pressure of the air and the cold material. After the airflow and pressure are regulated, the airflow and cold material enter the spray pipe 1 from the ends of the air supply pipe 101 and the material supply pipe 1011, respectively, and are uniformly mixed inside the spray pipe 1. The mixed cold material moves along the cavity of the spray pipe 1 towards its outlet end under the propulsion of the airflow, and is finally sprayed out from the outlet of the spray pipe 1, acting on the surface of the workpiece to be coated, thus completing the cold material spraying operation. If the flow rate and pressure need to be adjusted according to the working conditions during the spraying process, the control valve plate 2 can be adjusted to the corresponding position by controlling the rotation direction and angle of the servo motor 3011, so as to achieve real-time dynamic control.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
