Problems solved by technology

However, there is a shortcoming in the existing melt flow rate measuring instrument, that is, the metal blade cannot accurately complete the full circle rotation when cutting the sample, and always rotates more than one circle, which leads to two problems. The first is the blade cutting The quality of the sample is deviated; the second is that the blade may block the outlet of the sample

Embodiment 1

[0020] The measuring instrument of the present invention comprises a plastic extruding device 1, an automatic material cutting device 2, a column 3, a base 4 and a control device 5; 3 is fixedly connected with the base 4; the plastic extrusion device 1 includes a heating barrel 6 and a discharge port 7 arranged at the bottom of the heating barrel 6, the plastic particles are heated and melted in the heating barrel 6, and the molten plastic is extruded Under the extrusion of the device, it flows out vertically downward from the discharge port 7 of the heating barrel 6; the automatic cutting device 2 is arranged at the lower end of the discharge port 7 of the heating barrel 6; the control device 5 is set In the base 4, the control device 5 is connected with the automatic material cutting device 2 through wires. The automatic cutting device 2 includes a support plate 8, a motor 9, a drive shaft 10, a blade 11 and a connection switch 12, and also includes a power supply 13 and a p...

Embodiment 2

[0022] This embodiment 2 is basically the same as embodiment 1, the difference is:

[0023] The blade 11 is in the shape of a spoon to facilitate cutting the molten plastic flowing out from the outlet 7 .

[0024] The working principle of the measuring instrument of the present invention is as follows: when the measuring instrument is in the initial state, that is, when it is not turned on, the power switch 14 is turned off, and the proximity switch 12 is turned on. After the experiment starts, that is, when the flow rate of the molten plastic is stabilized for a certain period of time after starting the machine, the control device 5 closes the power switch 14 according to the predetermined time, the above-mentioned circuit is turned on, the motor 9 is powered, and the drive shaft 10 and the blade 11 are driven. rotate. When the blade 11 rotates to a position within five degrees of the proximity switch 12, the proximity switch 12 is disconnected, the above-mentioned circuit i...

Abstract

The invention discloses a plastic-melt-flow-rate measuring instrument. The plastic-melt-flow-rate measuring instrument comprises a plastic extruding device, an automatic cutting device, standing columns, a base and a control device. The plastic extruding device is fixedly connected with the base through the two standing columns arranged on the base, and comprises a heating cylinder and a discharging opening; the automatic cutting device is arranged below the discharging opening in the heating cylinder; the control device is arranged in the base and connected with the automatic cutting device through a wire. By means of the plastic-melt-flow-rate measuring instrument, whole rotation of a blade can be accurately controlled, the mass deviation of fusion plastic cut by the blade is eliminated, and the plastic-melt-flow-rate measuring instrument can be widely used for industries such as plastic, food, light industries and cement.

Description

technical field [0001] The invention relates to a rate measuring instrument, in particular to a flow rate measuring instrument for plastic melt. Background technique [0002] The melt flow rate tester is used to measure the melt mass flow rate (MFR), melt volume flow rate (MVR) and melt density of thermoplastic resins. It is not only suitable for polycarbonate, nylon, fluorine, etc. Engineering plastics such as plastics and polyaryl sulfone are also suitable for testing plastics with low melting temperatures such as polyethylene, polystyrene, polypropylene, ABS resin, and polyoxymethylene resin. They are widely used in plastic raw materials, products, petrochemical industries, etc. And related colleges and universities, research institutes and commodity inspection departments. [0003] The working principle of the melt flow rate test is: melt the plastic particles at high temperature, let the molten plastic flow out from the discharge port, turn the metal blade to cut the f...
