Embodiment 1

[0015] Such as figure 1 As shown, an automatic metering hopper is installed on the feed port of the plastic extruder through a support 6 . The hopper pressure sensing device 5 is installed between the bottom of the main hopper 8 and the support 6 . The hopper pressure sensing device 5 is a conventional known device that plays a weighing role similar to an electronic scale, and is mainly composed of a columnar pressure sensor, a data processing chip and a display screen. Hopper pressure sensing device 5 displays tare weight and net weight in real time. The plastic granules in the main hopper 8 fall into the feed port of the extruder along the pipeline by gravity. The weight of the main hopper 8 and all parts on it is applied to the columnar pressure sensor. The weight value weighed before feeding is the tare weight of the hopper, and the weight value weighed after feeding is subtracted from the tare weight of the hopper. The weight is the weight of the plastic.

Embodiment 2

[0020] On the basis of embodiment 1, a data interface is added to the feed pressure sensing device 3 and the hopper pressure sensing device 5, and the cumulative feed quantity of the feed hopper 10 and the real-time material quantity in the main hopper 8 are two The data is transmitted to the production line computer.

[0021] When the production line is running, collect the real-time manufacturing length and material quota data of online products to calculate the rated material consumption, collect the accumulated feed quantity of the feed hopper 10 minus the real-time material quantity in the main hopper 8 and then subtract the material in the screw barrel of the extruder The actual material consumption is obtained after the empirical quantity, and the production status can be understood in real time by comparing the data of the actual material consumption and the rated material consumption. The operator can reset the collected and calculated data at any time. In this way, w...

Abstract

The invention discloses an automatic metering hopper. The automatic metering hopper comprises a main hopper (8), a material level sensor (9) is arranged on the inner side wall of the main hopper (8),a hopper pressure sensing device (5) is arranged at the bottom of the main hopper (5), a support (6) is arranged at the bottom of the hopper pressure sensing device (5), a feeding pressure sensing device (3) is arranged on the upper end surface of the main hopper (8), and a feeding hopper (10) is arranged on the feeding pressure sensing device (3); a support (16) is arranged on the feed hopper (10), the support (16) is connected with a motor (13), a turnover plate valve cover (4) and a rotary opening and closing latch(7), the feeding hopper (10) is connected with an automatic feeder (11), andan electric control box (2) and a hot air blowing device (1) are arranged on the outer side surface of the main hopper (8). According to the automatic metering hopper, the feeding and discharging condition of the main hopper (8) can be displayed in real time, and realizing of fine management is facilitated.

Description

technical field [0001] The invention relates to the technical field of cable production material consumption management, in particular to an automatic weighing hopper. Background technique [0002] In the cable production process, plastic particles enter the plastic extruder through the hopper. Since plastic extrusion is continuous production, material consumption is a dynamic value. In order to control material consumption, reduce waste, evaluate the technical level of production operators, and improve the level of refined production management of the enterprise, it is necessary to have a hopper that can dynamically and real-time count the amount of incoming materials and the amount of remaining materials, so as to understand material consumption in real time and reduce waste. [0003] Currently, there are two types of hoppers installed on plastic extruders: small open and simple hoppers and closed hoppers with automatic feeding and drying devices. But neither of these two...
