Filling device capable of filling high-temperature and high-viscosity materials

Abstract

The invention discloses a filling device capable of filling high-temperature and high-viscosity materials, which comprises a frame, a charging barrel, reversing valves, filling pumps and a filling head, wherein the charging barrel, the filling pumps and the filling head are respectively arranged on the frame. The filling device is characterized in that the reversing valves are arranged on the charging barrel, a feeding port of each reversing valve is connected with a discharging port of the charging barrel, each filling pump is connected with a reversing passage of the corresponding reversing valve, and a discharging port of each reversing valve is connected with a feeding port of the filling head. The filling device is short in filling flow, and the high-temperature and high-viscosity materials are not easy to be cooled and solidified during filling, so that the high-temperature and high-viscosity materials can smoothly flow without retention, smooth filling and accuracy of the filling quantity are guaranteed, filling speed is increased, and production efficiency is also improved.

Description

technical field [0001] The invention relates to a filling device, in particular to a filling device capable of filling high-temperature and high-viscosity materials. Background technique [0002] Existing filling devices generally include a frame, a material barrel, a reversing valve, a filling pump and a filling head. The above-mentioned material barrel, reversing valve, filling pump and filling head are respectively arranged on the frame. The material pipe is connected to the feed port of the reversing valve. The filling pump is set on the reversing valve. The filling pump is connected to the reversing channel of the reversing valve. Feed port connection. [0003] Because the discharge port of the barrel of the existing filling device is connected with the feed port of the reversing valve through the feed pipe, and the discharge port of the reversing valve is connected with the feed port of the filling head through the feed pipe, so when filling When the material is a hi...

Problems solved by technology

[0003] Because the discharge port of the barrel of the existing filling device is connected with the feed port of the reversing valve through the feed pipe, and the discharge port of the reversing valve is connected with the feed port of the filling head through the feed pipe, so when filling When the material is a high-temperature and high-viscosity material, the high-temperature and high-viscosity material is easy to be cooled and solidified in the material tube, so that part of the material stays in the material tube, resulting in unsmooth filling, inaccurate filling volume, and sometimes even material Blockage phenomenon, thus affecting the smooth progress of filling

[0004] Therefore, the existing filling device is only suitable for the filling of low-viscosity liquid materials, not suitable for the filling of high-temperature and high-viscosity materials
