[0023] DETAILED DESCRIPTION
[0024] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.
[0025] Currently, the covering material telescopic nozzle device used in the electrolysis process mainly uses compressed air to control the telescopic action of the cylinder, thereby realizing the conveying and interruption of the material.
[0026] However, in the prior art, once the power or gas is cut off, the cylinder assembly that should be controlled by compressed gas may automatically open due to the loss of pressure support, thereby causing the material in the downpipe to lose control and resulting in the occurrence of material leakage. This not only makes the material that should be accurately put into the predetermined position, but also causes dust due to the scattering of the material, which adversely affects the working environment and air quality. More seriously, material leakage means that the material in the production process is wasted, which not only increases the production cost, but also may affect the operation efficiency and product quality of the entire production line.
[0027] Please refer to Figures 1 to 4 , in order to solve the above technical problems, the present application provides a cylinder self-locking device 100100, wherein the cylinder self-locking device 100 includes a shell 1, a cylinder assembly 2 and an electric control device 3. Wherein the shell 1 is hollow to form a mounting space, the cylinder assembly 2 is located in the mounting space, the cylinder assembly 2 has a movable part 21, the movable part 21 is telescopic to realize the feeding and stopping; and the electric control device 3 includes an electric drive assembly 31 and a self-locking assembly 32, the electric drive assembly 31 and the self-locking assembly 32 are located in the mounting space, the electric drive assembly 31 and the cylinder assembly 2 are connected to control the telescopic action of the cylinder assembly 2, and the self-locking assembly 32 is located between the electric drive assembly 31 and the cylinder assembly 2 to connect the electric drive assembly 31 and the cylinder assembly 2.
[0028] It can be understood that the shell 1 is used to accommodate the cylinder assembly 2 and the electric control assembly, and at the same time, it bears the above-mentioned assemblies and also plays a certain protection effect. The cylinder assembly 2 has a movable part 21 which is in telescopic motion to realize feeding or stopping action. The self-locking assembly 32 is located between the electric drive assembly 31 and the cylinder assembly 2, and is used to connect the above-mentioned assemblies and also to realize the self-locking function. In the process of normal operation, the self-locking assembly 32 is in an open state, and it connects the electric drive assembly 31 and the cylinder assembly 2 to conduct the compressed gas. In the power-off state, the self-locking assembly 32 is used to control the action of the cylinder assembly 2. The specific principle is that part of the structure of the self-locking assembly 32 is locked to maintain the closed state, thereby preventing the passage of fluid, and there is no fluid driving the cylinder assembly 2, so that the movable part 21 can maintain the original state, thereby realizing the self-locking function, solving the material leakage caused by cylinder leakage in power failure, and avoiding material waste and dust caused by material leakage.
[0029] In some embodiments, please refer to Figure 1 and Figure 2 The self-locking assembly 32 includes a self-locking valve 321, which includes a main body, a valve core, a reset assembly and a control assembly. The main body is provided with an air inlet and an air outlet, and a valve is also provided on the main body. The valve core is movably located in the main body and is used to cooperate with the main body to block or open the valve. The reset assembly is located in the main body and is connected with the valve core to drive the movement of the valve core. The control assembly is used to control the movement of the valve core to make the cooperation between the valve core and the main body be released.
[0030] The cooperation between the main body and the valve core can realize the opening and closing of the self-locking valve 321. In the cooperation process of the valve core and the main body, the valve can be accurately blocked or opened to control the flow of gas. In the embodiments of the present application, the control assembly is connected with the power supply. In the power-on state, the control assembly controls the valve core of the self-locking valve 321 to be away from the valve of the main body, and the reset assembly is used to push the valve core to move in the direction of approaching the valve of the main body. The existence of the reset assembly makes the valve core be able to reset to the closed state when needed, which is very important for system start, fault recovery or safety protection. The reset assembly can ensure that the valve core can safely return to the closed position when losing control or system failure.
[0031] It can be understood that the reset assembly includes an elastic member which is connected with the valve core to maintain the valve core in the locked position. The control assembly is connected with the valve core and is used to drive the valve core to move to release the lock. The elastic member can be a spring. In the power-on state, the spring is in a shortened state to accumulate elastic force. In the power-off state, the control force of the control assembly on the valve core disappears, at which time the spring pushes the valve core to cooperate with the main body to close the valve, thereby ensuring the self-locking function and preventing waste and dust caused by material leakage.
[0032] In addition, please refer to Figure 1 and Figure 2 The electric drive assembly 31 includes a solenoid valve 311 connected with the self-locking assembly 32. The solenoid valve 311 includes an electromagnet that attracts an iron core through the magnetic field generated when the coil is energized, thereby achieving control of the opening and closing of the valve. In the present application, the advantage of using the solenoid valve 311 for control is that the solenoid valve 311 has high precision, and the high-precision control of compressed air by the solenoid valve 311 can meet the requirements of complex processes for medium flow parameters. Moreover, the solenoid valve 311 is fast, and can achieve the opening or closing of the valve in a short time, facilitating the rapid control of the cylinder assembly 2 and thereby achieving a rapid response to loading or stopping loading. In other embodiments, other control valves can also be used to control the cylinder assembly 2, as long as they can achieve the function of opening and closing the valve, which is not limited in the present application.
[0033] In addition, please refer to Figure 3 The housing 1 is cylindrically arranged, and has two ends arranged oppositely, one of which is provided with a discharge hole 11, and the movable part 21 of the cylinder assembly 2 is used to approach or move away from the discharge hole 11. It can be understood that, since the movable part 21 of the cylinder assembly 2 moves along the inside of the housing 1 to achieve pushing and feeding, the housing 1 is not completely closed, and is provided with a discharge hole 11 for the material to pass through. The size of the discharge hole 11 can be adjusted according to the size of the required material to adapt to different discharge requirements.
[0034] Further, the cylinder self-locking device 100 further includes a guide plate 12 arranged corresponding to the discharge hole 11, and the guide plate 12 is detachably installed at the housing 1. It can be understood that the guide plate 12 is arranged corresponding to the discharge hole 11 to ensure that the material can pass through the guide plate 12 to achieve the desired position, thereby ensuring the accuracy of the material transportation position to a certain extent. Moreover, the guide plate 12 is detachably arranged, and different types of guide plates 12 can be flexibly detached and replaced to achieve the accuracy and flexibility of different material transportation.
[0035] In addition, in other embodiments, the guide plate 12 is rotatably installed at the housing 1, thereby being able to adjust the angle of the guide plate 12 for transporting the material, facilitating precise feeding. In this way, the guide plate 12 can better adapt to the actual conditions without the need to adjust the angle of the housing 1, and only needs to be rotated to achieve precise transportation of the material.
[0036] In addition, please continue to refer to Figure 3The shell 1 further comprises an end cover 13, and the end cover 13 and the shell 1 are detachably arranged, and the discharge hole 11 is located on the end cover 13. In the embodiment of the present application, the shell 1 is provided with a detachable end cover 13, thereby ensuring that the shell 1 in the present application can be disassembled and installed, thereby ensuring that the devices located inside the shell 1, such as the cylinder assembly 2, the self-locking assembly 32 or the electric drive assembly 31, can also be disassembled from the inside of the shell 1, facilitating subsequent maintenance and replacement, thereby prolonging the service life of the cylinder self-locking device 100.
[0037] It can be understood that the detachable mode between the shell 1 and the end cover 13 includes a buckle connection mode, a bolt and nut connection mode, a slot type connection mode and the like, as long as the function of convenient disassembly and assembly can be realized, which is not limited in the present application.
[0038] Further, a sealing element 14 is further arranged between the end cover 13 and the shell 1, and the sealing element 14 is used to connect the end cover 13 and the shell 1. It can be understood that a sealing element 14 is arranged between the end cover 13 and the shell 1. The sealing element 14 is used to enhance the connection stability between the end cover 13 and the shell 1, and can also effectively ensure the sealing performance of the equipment. The sealing element 14 is usually made of wear-resistant and corrosion-resistant materials to ensure that it can still maintain excellent sealing performance in various harsh working environments. At the same time, the sealing element 14 also ensures the convenience of installation and disassembly, making the maintenance and maintenance work of the equipment become more easy. During the installation process, the sealing element 14 is placed on the contact surface between the end cover 13 and the shell 1, and is tightly fitted between the two through appropriate fastening force, forming a complete sealing structure. In this way, the inside of the shell 1 is in a closed state, avoiding the leakage and overflow of the material.
[0039] In addition, the sealing element 14 also has a certain elasticity, which can automatically compensate for the slight deformation caused by temperature changes, vibration and other factors during the operation of the equipment, thereby maintaining long-term sealing effect.
[0040] Please refer to Figure 4The movable part 21 comprises a movable rod 211 driven by the cylinder assembly 2 to move within the housing 1, and a scraping plate 212 located at the end of the movable rod 211 away from the cylinder assembly 2, the scraping plate 212 being configured to contact the inner wall of the housing 1 and move with the movable rod 211. The movable rod 211 is driven by the cylinder assembly 2 to move within the housing 1, so that the movable rod 211 can quickly respond to the instruction of the cylinder assembly 2, thereby effectively driving the movement of the scraping plate 212 installed at the end of the movable rod 211 away from the cylinder assembly 2, so as to ensure that the scraping plate 212 can closely and uniformly contact the inner wall of the housing 1. The scraping plate 212 has wear resistance and toughness, and can maintain stable scraping effect in a long time of work, while reducing wear caused by friction. When the cylinder assembly 2 drives the movable rod 211 to move, the scraping plate 212 also moves. With the reciprocating movement of the movable rod 211, the scraping plate 212 closely contacts the inner wall of the housing 1, effectively scraping the material or residue attached to the wall. This can improve the cleaning efficiency of the interior of the housing 1, and avoid the accumulation of material on the inner wall of the housing 1, thereby ensuring the normal operation of the equipment and the efficient use of the material.
[0041] In some embodiments, the scraping plate 212 is provided in multiple numbers, thereby further ensuring the efficiency of the pushing of the material within the housing 1.
[0042] In addition, the scraping plate 212 can be detachably arranged at the movable rod 211. Thus, different materials, different shapes of the scraping plate 212 can be replaced according to different types of materials, and after the scraping plate 212 is damaged, it can also be conveniently disassembled and replaced with a new scraping plate 212 to meet the scraping requirements.
