Problems solved by technology

[0004] When the feeder is used for solid feeding, the hopper of the existing single / twin-screw feeder adopts a ball bucket with a hemispherical bottom. Due to the relatively small opening at the bottom, the material transportation is not smooth enough, and it is also not conducive to to stir
Therefore, in the case of solid feeding, its structure needs to be improved

Embodiment Construction

[0018] The weightless feeding machine of the present invention adopts the bus control mode, and the user inputs the corresponding proportioning parameters through the input device of the industrial computer, including the display of the industrial computer or a touch panel computer, including the mixing ratio of multiple groups of materials, which can be input separately, The total flow can also be input, and the proportion is automatically distributed. At the same time, the signal is transmitted to the PLC control system through the load sensor. After timely processing by the software program, the control system outputs a timely adjusted signal to the frequency converter, and the stability of the flow is realized through the motor, metering pump and other actuators.

[0019] see Figure 2a with Figure 2b , in the metering and compounding method of the loss-in-weight feeder of the present invention, after the system is powered on, input the set proportioning parameters throu...

Abstract

An agravity-type solid and liquid feeder features that the weighing unit for feeding liquid has metering and external metering drums connected respectively to load sensors, and the single (or dual) screw feeding mechanism for feeding solid has a dished hopper under feeding hopper. Its metering-mixing method includes such steps as setting up the mixing rate by industrial control computer, obtaining weigh signal by load sensor, transmitting it to PLC module, and outputting real-time regulating signal to feeding unit for controlling the feeding while regulating the flow stability.

Description

technical field [0001] The invention relates to a feeding device, in particular to a loss-in-weight feeding machine for liquid feeding. Background technique [0002] With the rapid development of the rubber and plastic industry in China, more and more loss-in-weight metering feeding and compounding equipment from abroad have entered the domestic market. However, the price of imported machines is quite expensive, and most domestic small and medium-sized enterprises cannot afford it. Domestic loss-in-weight feeders for liquid feeding are still blank. [0003] When the feeder is used in chemical, pharmaceutical, food and other fields, the liquid material will reflect and deteriorate when it encounters air, or react or crystallize when encountering moisture in the air. The existing feeder products cannot ensure the physical and chemical properties of the material, and lack a closed structure to prevent the material from volatilizing. Therefore, in the case of liquid feeding, ...
