Description

Technical Field

[0001] The utility model relates to the technical field of welding smoke treatment, in particular to a liquid rubber quantitative filling device. Background Art

[0002] Liquid rubber refers to a type of rubber material that is liquid at room temperature. It is composed of low molecular weight polymers and has the characteristics of strong fluidity and processability. In order to facilitate the filling of liquid rubber, a liquid rubber quantitative filling device is required.

[0003] A search revealed a Chinese patent publication number of CN216005191U, which discloses a high-viscosity liquid rubber packaging device. The device comprises a mounting frame and a support platform. A kettle is mounted within the mounting frame, with an inlet opening at the top of the kettle and a discharge pipe fixedly connected to the bottom of the kettle. The discharge pipe is equipped with an automatic discharge regulating valve. A coil is mounted on the surface of the kettle, and the bottom of the coil is fixedly connected to an air inlet pipe. This device incorporates an automatic nitrogen regulating valve at the top of the kettle, which is interlocked with the pressure to establish a constant positive pressure within the kettle, thereby facilitating the discharge of material from the kettle. Furthermore, an automatic regulating valve is interlocked with the weighing system on the weighing machine on the packaging equipment's material pipeline, improving packaging accuracy and convenience while reducing contamination of the outer packaging and the ground. Furthermore, an electrically heated jacket is employed on the material pipeline to maintain a constant material temperature, particularly in winter to prevent excessive viscosity of the low-temperature material from preventing it from flowing. However, in actual use, the device cannot adjust the amount of liquid rubber being filled, resulting in an inability to perform quantitative dosing during filling, thereby reducing its practicality.
