Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of production line, in particular to a safety protection system of annealing tinning machine production line. BACKGROUND

[0002] During the use of the annealing tinning machine production line, various dangerous situations may occur, especially fire, which is mainly caused by the following two aspects: first, the annealing process: the metal parts (here copper wire) need to be heated to a high temperature state during the annealing operation, and if the temperature control is not proper or the equipment fails, a fire accident may occur. Second, tin furnace heating: the tin furnace is usually equipped with heating devices such as electric heating pipes, and if these devices fail or are not operated properly, a fire may also occur.

[0003] At present, the existing technology mainly focuses on prevention in response to the fire situation of the annealing tinning machine production line, mainly including the installation of smoke detectors and the setting of combustible gas detectors, installing smoke detectors around the production line and in key areas to discover fire signs in time, and setting combustible gas detectors to monitor the areas where combustible gas may exist in real time to ensure that there is no leakage of combustible gas. However, the above methods cannot guarantee active fire extinguishing when a fire occurs. Since the annealing tinning machine production line is usually large in size, the position of the traditional automatic fire extinguisher is fixed, and the range of the spray head is limited, there are many dead angles in the actual application process, and it is difficult to ensure that the spray head is aligned with each production line position. Therefore, even if a fire occurs, it is difficult to ensure that the fire extinguishing agent is accurately sprayed at the fire source position using the automatic fire extinguisher device, thereby reducing the safety of the scene, increasing the risk of personnel, and increasing the loss of enterprises. In view of the deficiencies of the prior art, the present application provides a safety protection system of annealing tinning machine production line to solve the above problems. SUMMARY

[0004] In view of the deficiencies of the prior art, the present application provides a safety protection system of annealing tinning machine production line, which realizes efficient response and fire extinguishing action, monitors the smoke concentration of the target position of the production line in real time, can quickly discover and take action at the early stage of fire, and at the same time, once the fire is detected, the main control unit immediately starts the electric control fire extinguisher to release the fire extinguishing agent, and drives the fire nozzle to cover the fire position for spraying. The cooperation of the transmission unit and the self-rotation assembly enables the fire nozzle to perform circular periodic motion around the annealing tinning machine production line equipment while the fire nozzle itself constantly rotates. The fire extinguishing agent sprayed by the fire nozzle forms a large range of active spraying path, realizing multi-angle, multi-position and multi-frequency spraying, so that a group of nozzles can realize large range and multi-angle fire extinguishing agent spraying, covering the entire annealing tinning machine production line equipment above, improving the fire extinguishing effect, increasing the stability of the safety protection system, and reducing the loss when the annealing tinning machine production line equipment encounters an accident.

[0024] 1. The safety protection system of this annealing and tin plating machine production line achieves efficient response and fire extinguishing actions. It monitors the smoke concentration at the target location on the production line in real time, enabling rapid detection and action in the early stages of a fire.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] This application provides a safety protection system for an annealing tin plating machine production line. This system addresses the problem that traditional automatic fire extinguishers, due to the typically large size of the production line and their fixed locations and limited nozzle spray range, often result in blind spots during practical application. This makes it impossible to ensure the nozzles are accurately aimed at every production line location. Consequently, even in the event of a fire, automatic fire extinguishers struggle to precisely cover the fire source, reducing on-site safety, increasing personnel risks, and escalating company losses.

[0041] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0042] This invention discloses a safety protection system for an annealing tin plating machine production line, according to the appendix. Figures 1-10 As shown, the protective support body 1 is installed above the annealing tin plating machine production line equipment. The protective support body 1 is equipped with a main controller 2, a monitoring unit 3, a fire extinguishing unit 4, a bearing seat 5, a transmission unit 6, and a self-rotating component 7.

[0043] The protective support body 1 is set above the annealing tin plating machine production line equipment and serves as the support structure for the entire safety protection system. The protective support body 1 includes a wall frame 11 and an overhead frame 12. The wall frame 11 is fixedly connected to the wall, and the overhead frame 12 is set on the wall frame 11.

[0044] The main controller 2 is installed on the main body 1 of the protective bracket and is the control center of the entire safety protection system. The main controller 2 is responsible for receiving fire occurrence information from the monitoring unit 3 and controlling the fire extinguishing unit 4, transmission unit 6 and self-rotating component 7 to perform corresponding actions.

[0045] The monitoring unit 3 is connected to the main controller 2 and is used to monitor the fire occurrence information at the target location of the production line. The monitoring unit 3 includes a fan 31 fixedly connected to the main body 1 of the protective support and a pipe 32 fixedly connected to the fan 31. A smoke sensor 33 is installed on the pipe 32. The fan 31 draws in air from the target location of the production line through the pipe 32, and the smoke sensor 33 detects the smoke concentration in the pipe 32 to determine whether a fire has occurred.

[0046] Fire extinguishing unit 4 is connected to main controller 2 and is used to extinguish fires when a fire occurs. Fire extinguishing unit 4 includes an electric fire extinguisher 41, a transmission pipe 42 installed on the electric fire extinguisher 41, and a fire sprinkler head 43 connected to the transmission pipe 42. Fire extinguishing unit 4 performs fire extinguishing actions when a fire occurs.

[0047] When the electronically controlled fire extinguisher 41 receives the instruction from the main controller 2, it activates and delivers the extinguishing agent to the fire sprinkler head 43 through the transmission pipe 42 for spraying.

[0048] The support seat 5 is installed on the main body 1 of the protective bracket and is used to support the fire sprinkler head 43;

[0049] The transmission unit 6 is mounted on the protective support body 1 and connected to the bearing seat 5. The transmission unit 6 is used to drive the bearing seat 5 and the fire sprinkler head 43 to move. The transmission unit 6 includes a motor 61 fixedly connected to the protective support body 1 and a rotating plate 62 fixedly connected to the output end of the motor 61. The rotating plate 62 is provided with an eccentric shaft 63. A movable rod 64 is rotatably connected to the eccentric shaft 63. A vertical block 51 is connected to the bearing seat 5. The movable rod 64 is fixedly connected to the vertical block 51.

[0050] A longitudinal rail 67 is connected to the main body 1 of the protective bracket. A transverse rail 66 is slidably connected to the longitudinal rail 67. A limit block 65 is slidably connected to the transverse rail 66. The limit block 65 is fixedly connected to the movable rod 64.

[0051] The transmission unit 6 is installed on the main body 1 of the protective bracket and is used to drive the bearing seat 5 and the fire sprinkler head 43 to move. The main controller 2 starts the motor 61 at the same time as starting the fire extinguishing unit 4. The motor 61 drives the rotating plate 62 to rotate when it is working. The rotating plate 62 drives the eccentric shaft 63 to rotate. The eccentric shaft 63 drives the movable rod 64 to move. The movable rod 64 drives the bearing seat 5 and the fire sprinkler head 43 to move. During the movement, the movable rod 64 is limited by the limiting block 65, the transverse rail 66 and the longitudinal rail 67. Therefore, the bearing seat 5 and the fire sprinkler head 43 are driven to form a circular periodic motion.

[0052] The rotation component 7 is installed on the protective support body 1. The rotation component 7 is used to control the rotation of the fire sprinkler head 43. The rotation component 7 includes a gear 73 fixedly connected to the protective support body 1 and a rotating tube 71 rotatably connected to the support seat 5. The rotating tube 71 is connected to the fire sprinkler head 43. A gear 72 is provided on the rotating tube 71, and the gear 72 meshes with the gear 73.

[0053] When the main controller 2 controls the fire sprinkler head 43 to spray and the transmission unit 6 is also working, it will drive the carrier 5 and the fire sprinkler head 43 to form a circular periodic motion. Therefore, the gear 72 in the self-rotating assembly 7 moves around the gear disk 73. The gear disk 73 drives the gear 72 to move, which in turn drives the rotating tube 71 to rotate. The rotating tube 71 is connected to the fire sprinkler head 43, so the fire sprinkler head 43 also rotates, realizing the uniform spraying of the extinguishing agent and improving the fire extinguishing effect.

[0054] Based on this, during the process of triggering the fire extinguishing agent spray, the fire nozzle 43 performs a circular cyclical movement around the annealing tin plating machine production line equipment while continuously rotating itself. The fire extinguishing agent sprayed by the fire nozzle 43 forms a large-scale active spray path, thereby achieving a large-scale fire extinguishing agent spray through a group of nozzles, covering the entire annealing tin plating machine production line equipment, improving the fire extinguishing effect, increasing the stability of the safety protection system, and reducing losses in the event of an accident involving the annealing tin plating machine production line equipment.

[0055] A turntable 54 is rotatably connected to the support base 5, and a rotating tube 71 is fixedly connected to the turntable 54. A rotating component 53 is provided on the rotating tube 71, and a hollow groove 531 is opened on the rotating component 53. A sleeve 52 is fixedly connected to the vertical block 51, and the rotating component 53 is rotatably connected inside the sleeve 52. The transmission tube 42 is fixed and connected to the sleeve 52. When the rotating tube 71 rotates, the rotational connection between the rotating component 53 and the support base 5 provides a limit to ensure the rotational stability of the fire sprinkler head 43 and the rotating tube 71. When the rotating tube 71 rotates, it drives the rotating component 53 to rotate along the sleeve 52. The extinguishing agent of the electric fire extinguisher 41 is transported to the inside of the sleeve 52 through the transmission tube 42, enters the inside of the rotating tube 71 through the hollow groove 531, and then sprays the extinguishing agent out through the fire sprinkler head 43 through the rotating tube 71.

[0056] A docking unit 8 is provided between the fire sprinkler head 43 and the turntable 54. The docking unit 8 includes a snap-fit ​​seat 81 set on the turntable 54 and a snap-fit ​​block 82 connected to the fire sprinkler head 43. The snap-fit ​​block 82 is movably snapped into the inside of the snap-fit ​​seat 81. A locking component 83 is provided on the side of the snap-fit ​​seat 81. Through the design of the docking unit 8, this device makes it easy to quickly install and remove the fire sprinkler head 43, thereby ensuring convenient maintenance of the fire sprinkler head 43, convenient regular inspection of the fire sprinkler head 43, good stability, and easy upgrading and replacement in the future. When the fire sprinkler head 43 is installed, it can be directly snapped into position by the snap-fit ​​block 82 and the snap-fit ​​seat 81, and then quickly locked by the locking component 83.

[0057] The locking assembly 83 includes a sleeve 831 fixedly connected to the snap-fit ​​seat 81 and a locking rod 832 slidably connected to the sleeve 831. The snap-fit ​​block 82 has a locking hole 821, and the locking rod 832 is movably snapped into the locking hole 821. The locking rod 832 has an adjusting block 833 slidably connected to the inside of the sleeve 831. A spring 834 is fixedly connected between the adjusting block 833 and the sleeve 831.

[0058] The locking assembly 83 has a compact structure and is convenient for locking the fire sprinkler head 43 during installation. Before the locking block 82 and the locking seat 81 are engaged, the adjusting block 833 is pulled, causing the adjusting block 833 to compress the spring 834 and simultaneously move the locking rod 832. When the locking block 82 and the locking seat 81 are engaged, the adjusting block 833 is released, causing the spring 834 to reset and push the adjusting block 833 and the locking rod 832 to move. Finally, the locking rod 832 is inserted into the lock hole 821, thereby locking the locking block 82 and the locking seat 81 and locking the fire sprinkler head 43 during installation.

[0059] A reinforcing column 822 is fixedly connected between the fire sprinkler head 43 and the locking block 82. A connecting pipe 823 is connected to the fire sprinkler head 43. The connecting pipe 823 is connected to the reinforcing column 822, the locking block 82, the locking seat 81, the turntable 54, the bearing seat 5, and the rotating pipe 71. This device connects the fire sprinkler head 43 and the locking block 82 through the reinforcing column 822. By using different lengths of the reinforcing column 822, the tilt angle of the fire sprinkler head 43 can be changed, thereby ensuring that the coverage range of the fire sprinkler head 43 during fire extinguishing is exactly matched with the annealing and tin plating production line equipment on site. When the extinguishing agent inside the rotating pipe 71 is transported, it enters the bearing seat 5, the turntable 54, the locking seat 81, the locking block 82, the reinforcing column 822, and the connecting pipe 823 through the rotating pipe 71, and is finally sprayed out from the fire sprinkler head 43.

[0060] The main body 1 of the protective bracket includes a wall frame 11 fixedly connected to the wall and an overhead frame 12 set on the wall frame 11. The overhead frame 12 is used to support the main controller 2 and the motor 61. The wall frame 11 is used to support the fan 31, the smoke sensor 33, the electric fire extinguisher 41 and the gear disc 73. A reinforcing rib 511 is fixedly connected between the vertical block 51 and the movable rod 64. The reinforcing rib 511 makes the connection between the vertical block 51 and the movable rod 64 stable. The main body 1 of the protective bracket has a compact structure, which facilitates the installation and support of key components such as the main controller 2 and the motor 61, and ensures that the device is easy to assemble.

[0061] Pipe 32 is connected to gear disc 73. Gear disc 73 has a flared opening 731 inside. Pipe 32 is connected to flared opening 731. Flared opening 731 is used to connect with pipe 32 to ensure that fan 31 can easily draw air from the target position above the production line equipment into pipe 32, thereby improving the monitoring effect of monitoring unit 3.
