Abstract
The utility model discloses a kind of weight-loss type pay-off, comprise feed bin (1), screw feeder passage (3) and on-the-spot feeder channel (4), described feed bin (1) is provided with weightless sensor (2), weightless sensor (2) connection control instrument; Described screw feeder passage (3) is provided with negative pressure device with the junction of on-the-spot feeder channel (4), and material roller rotates together along with screw feeder, effectively prevent the blocking of bin blanking mouth; Being flexible coupling to shrink because of negative pressure causes junction to block; Negative pressure device is set between two feeder channels and effectively improves blanking integrity degree.
Description
Technical field
The utility model relates to a kind of weight-loss type pay-off, comprises feed bin, screw feeder passage and on-the-spot feeder channel.
Background technology
Weight loss feeder) be made up of hopper, feeder, weighing system and regulating control, in operation, hopper, material and feeder are weighed jointly continuously.After material sends, measure real weight loss rate, and it is compared with required weight loss rate.Weight loss feeder carrys out by reconciling feeder speed the inclined value that auto modification departs from set point.Thus evenly can feed material continuously exactly.
Weight loss feeder is applicable to scope and comprises a plastics material, powder, calcium carbonate, french talc, resin molding powder product, flour, and starch etc., therefore there will be in feeding process between hopper and feeder and block, the problem of feeder feed opening blocking.
Utility model content
The purpose of this utility model is to provide a kind of weight-loss type pay-off.
The technical solution adopted in the utility model is: a kind of weight-loss type pay-off, and comprise feed bin, screw feeder passage and on-the-spot feeder channel, described feed bin is provided with weightless sensor, weightless sensor connection control instrument; Described screw feeder passage and the junction of on-the-spot feeder channel are provided with negative pressure device.
As further improvement of the utility model, the junction of screw feeder passage and on-the-spot feeder channel is flexible coupling, and being flexible coupling is by some circle steel wires as skeleton, outside parcel soft rubber.
As further improvement of the utility model, the junction of screw feeder passage and feed bin is provided with material roller, be provided with Timing Belt between the motor output shaft of material roller and screw feeder passage.
The beneficial effects of the utility model are: material roller rotates together along with screw feeder, effectively prevent the blocking of bin blanking mouth; Being flexible coupling to shrink because of negative pressure causes junction to block; Negative pressure device is set between two feeder channels and effectively improves blanking integrity degree.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Shown in figure: 1 feed bin, 2 weightless sensors, 3 screw feeder passages, 4 on-the-spot feeder channels, 5 are flexible coupling.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model detailed description of the invention is elaborated.
As shown in Figure 1, the present embodiment comprises feed bin 1, screw feeder passage 3 and on-the-spot feeder channel 4, and feed bin 1 is provided with weightless sensor 2, weightless sensor 2 connection control instrument; Screw feeder passage 3 is provided with negative pressure device with the junction of on-the-spot feeder channel 4, screw feeder passage 3 is be flexible coupling 5 with the junction of on-the-spot feeder channel 4, be flexible coupling (5) be as skeleton by some circle steel wires, outside parcel soft rubber, negative pressure device is set between two feeder channels and effectively improves blanking integrity degree, screw feeder passage 3 is provided with material roller with the junction of feed bin 1, is provided with Timing Belt between the motor output shaft of material roller and screw feeder passage 3.
Principle of work:
Feed bin quick feeding reaches and stops charging in limited time, device for discharging works according to given discharge rate (feeding coal), control instrument is by the change calculations discharging flow of weight of material in the unit time, feed is started in limited time under mass flow in feed bin is less than, because material passes in and out feed bin simultaneously, so do not measure discharging flow by changes in weight during material loading, now control instrument enters dosage by volume mode, when feeding process terminates (the general time is very short), system recovers weight-loss metering mode again automatically.
The load signal of weighing bucket is delivered in instrument and is processed by sensor, sampling scale body being carried out to weight signal is not stopped by instrument, calculate the changing ratio of weight in the unit time as instant flow rate, again by the filtering technique process of various software and hardware, drawing can as " actual flow " of control object.
Below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned embodiment, in the ken that art those of ordinary skill possesses, can also make a variety of changes under the prerequisite not departing from the utility model aim.
