Description

Technical Field

[0001] The present application relates to the technical field of fire extinguishers, and specifically discloses a filling and punching device for a fire extinguisher. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool, usually including a tank body and a fire extinguishing agent stored in the tank body. Currently, the more commonly used fire extinguishers are heptafluoropropane fire extinguishers. Heptafluoropropane is a clean gas chemical fire extinguishing agent that mainly extinguishes chemical fires and also has physical fire extinguishing effects. It is colorless, odorless, low-toxic, non-conductive, does not pollute the protected object, and will not cause damage to financial and precision facilities. Therefore, heptafluoropropane fire extinguishers are used more and more widely. The existing heptafluoropropane fire extinguisher production method is to manually move the fire extinguisher tank body, and then connect the filling port with the feed port of the fire extinguisher for filling. However, since the feed port and the injection pipe are arranged inside the fire extinguisher, there will be alignment deviations during manual filling, resulting in filling leakage, and since the fire extinguisher lacks a positioning structure, the fire extinguisher may tip over during filling due to production collision.

[0003] Therefore, in view of this, the inventor provides a fire extinguisher filling and punching device to solve the above-mentioned problem. Utility Model Content

[0004] The utility model aims to solve the problem that the existing filling and punching device of the fire extinguisher lacks a positioning structure and the tank body is prone to filling leakage and dumping.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a fire extinguisher filling and punching device, including a production rack, a punching structure arranged on the production rack, a plurality of filling structures arranged on the production rack and a stepping conveying structure for conveying a tank body so that the tank body passes through the punching structure and the filling structure in sequence. The filling structure includes a storage tank for storing a fire extinguishing agent, a filling pipe connected to the storage tank for filling the tank body with the fire extinguishing agent, and a solenoid valve for controlling the opening and closing of the filling pipe. The outer wall of the filling pipe can be detachably connected with a positioning plate, and also includes a plurality of fixing rings whose number is equal to the filling pipe and whose axis is directly opposite to the filling pipe. The fixing rings are used to fix the position of the tank body, and the bottom of the positioning plate is provided with a fixing structure for fixing the position of the fixing rings.

[0006] The principles and effects of this basic solution are:

[0007] 1. Compared with the prior art, the utility model positions the tank body by setting a fixed collar so that the inner wall of the fixed collar is in contact with the tank body, and makes the filling port face the air inlet valve port, which is convenient for docking. At the same time, due to the supporting effect of the fixed structure and the fixed collar on the fire extinguisher, the tank body is prevented from tipping over during filling, which solves the problem that the existing fire extinguisher filling and punching device lacks a positioning structure and is prone to filling leakage and tipping.

[0008] 2. The utility model provides a step-by-step conveying structure, so that the tanks can be punched and filled in sequence without the need for personnel to move them, thereby improving production efficiency.

[0009] Furthermore, the fixing structure includes a plurality of fixing sleeves fixed to the bottom of the positioning plate and a sliding sleeve slidably connected in the fixing sleeve and having one end of the top extending out of the fixing sleeve and the positioning plate in turn. One end of the bottom of the sliding sleeve is fixed to the fixing collar, and a section of the top of the sliding sleeve extending out of the positioning plate is provided with an external thread, and also includes a nut provided with an internal thread and threadedly connected to a section of the top of the sliding sleeve extending out of the positioning plate. By loosening the nut, the sliding sleeve is not connected to the nut, and the nut cannot be limited, so that the sliding sleeve slides down and sticks to the outer wall of the tank body, thereby realizing the positioning of the tank body and facilitating the docking of the filling port. At the same time, because the fixing sleeve is fixed to the bottom of the positioning plate, the fixing collar supports the tank body.

[0010] Furthermore, the punching structure comprises a hydraulic push rod arranged on the production frame, a mounting seat arranged at the output end of the hydraulic push rod, and a punching member detachably connected to the mounting seat for punching holes. The hydraulic drive has strong power, so that the punching effect is better.

[0011] Furthermore, a buffer block for protecting the stepping conveying structure is fixedly connected to the bottom of the fixing collar, and the inner wall of the fixing collar is in contact with the outer wall of the tank body, so that a buffering effect is achieved.

[0012] Furthermore, the stepping conveying structure includes a belt conveyor and a stepping motor for driving the belt on the belt conveyor to intermittently move, and the stepping motor is electrically connected to a controller. The control is better through the sensor.

[0013] Furthermore, a pressure sensor is also provided on the fixing collar, and the pressure sensor is electrically connected to the controller. The pressure sensor can monitor the tank pressure to prevent the fire extinguishing agent from being injected too much and too quickly, causing the tank pressure to increase rapidly.
