Description
Technical field
The utility model relates to a kind of charging control mechanism, especially relates to the charging control mechanism of the packaging production line of a kind of use in the rubber production device.
Background technology
In the charging control process of numerous automatic packaging production lines, in Chemical Manufacture, comprise in the rubber production device especially; Accuracy control for inlet amount; What most manufacturing lines adopted is mode mechanically, also promptly closes bin gate in proportion, reaches the purpose of control inlet amount with this.But because the degree of closing of bin gate is difficult to accomplish to control accurately and timely, cause the deviation of weight fluctuation of material bigger, and be prone in control process, cause the obstruction of material, influence the unimpeded of manufacturing line.And common manufacturing line is in carrying out the accurate weighing process of material; What take is the mode of closing bin gate in proportion; Promptly when the weight of material that falls into weight box is near the mark weight, just bin gate is closed in proportion,, progressively reach std wt to reduce inlet amount.This mode control accuracy is not enough, and the weight of material deviation is bigger, and because the part of bin gate is closed, possibly cause the bigger material of some viscosity to stop up at the bin gate place.
The utility model content
The utility model influences the unimpeded of manufacturing line in control process, causing the obstruction of material in the charging control process that solves existing automatic packaging production line easily; Perhaps present situation such as control accuracy deficiency and provide a kind of simple in structure, can reach higher control accuracy, improve the charging control mechanism of packaging production line of unobstructed property and the efficient of manufacturing line.
The utility model is to solve the problems of the technologies described above the concrete technical scheme that is adopted to be: a kind of charging control mechanism of packaging production line; Comprise weight box; Thick feeding-passage and discharge door thereof is characterized in that: below the passage of thick feeding-passage, be provided with in order to isolate the inclination sieve plate of tiny material, inclination sieve plate below is provided with the material passage that progresses greatly; Progress greatly and expect to establish conveying mechanism in the passage; Material passage one end that progresses greatly is connected with the tapping channel of discharge door below, and conveying mechanism is connected with variable-frequency motor, and variable-frequency motor is connected on the PLC.The inclination sieve plate of thick feeding-passage below separates bulk materials, and bulk materials is directly sent into weight box, carries out thick feed; In the tiny material that the inclination sieve plate spills is fallen the material passage that progresses greatly, send into weight box through spiral conveying mechanism, carry out smart feed, spiral conveying mechanism is regulated delivery speed through frequency converter, makes feed more accurate.
As preferably, described conveying mechanism adopts spiral conveying mechanism.Simple in structure, carry effectively reliable.
As preferably; Be connected with LOAD CELLS, discharge door and major loop control system on the described PLC; LOAD CELLS is located at the weight box bottom, and PLC carries out logic determines according to the data that LOAD CELLS is sent into, and discharge door, variable-frequency motor, major loop control system are controlled." material that progresses greatly starts weight " is less than std wt, but the weight that relatively is near the mark; When weight of material in the weight box did not reach " material that progresses greatly starts weight " as yet, bin gate stayed open state, and material falls into weight box fast by thick feeding-passage; When the weight in the weight box reached " material that progresses greatly starts weight ", bin gate was closed, and frequency converter brings into operation, and the tiny material that spiral conveying mechanism will fall in the material passage that progresses greatly is sent into weight box; When the weight in the weight box reached " std wt ", frequency converter was out of service, and feeding finishes.
As preferably, the sieve aperture of described inclination sieve plate is 10 * 10 mm.Can the material less than this scope be screened, be input in the weight box, control more accurate from the material passage that progresses greatly.
The beneficial effect of the utility model is: the inclination sieve plate of thick feeding-passage below separates bulk materials, and bulk materials is directly sent into weight box, carries out thick feed; In the tiny material that the inclination sieve plate spills is fallen the material passage that progresses greatly, send into weight box through spiral conveying mechanism, carry out smart feed, spiral conveying mechanism is regulated delivery speed through frequency converter, makes feed more accurate; PLC gathers the weight of weight box in real time, calculates the poor of actual weight and std wt, through the differential and integral calculus feedback regulation, sends analog signal to frequency converter, precisely controls the output of frequency converter, and then the speed of transmission of control helical feed.Make the package technic index of producing reach higher accuracy, for the quality of product direct lifting is arranged, the running of frequency converter motor simultaneously according to technological condition adjustment in time, has improved energy-saving and cost-reducing effect fully to a certain extent.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed description.
Fig. 1 is the structural representation of preferred implementation of the charging control mechanism of the utility model packaging production line.
The control principle block diagram of the charging control mechanism of Fig. 2 the utility model packaging production line.
The specific embodiment
Among the embodiment shown in Figure 1; A kind of charging control mechanism of packaging production line comprises weight box 20, thick feeding-passage 10 and discharge door 11 thereof; Below the passage of thick feeding-passage 10, be provided with in order to isolate the inclination sieve plate 13 of tiny material; Inclination sieve plate 13 belows are provided with the material passage 30 that progresses greatly, and establish conveying mechanism 31 in the material passage 30 that progresses greatly, and material passage 30 1 ends that progress greatly are connected with the tapping channel 14 of discharge door 11 belows; Conveying mechanism 31 is connected with variable-frequency motor 32, and variable-frequency motor 32 is connected on the PLC50.Conveying mechanism 31 adopts spiral conveying mechanism.Last LOAD CELLS 40, discharge door 11 and the major loop control system 60 of being connected with of PLC50; LOAD CELLS 40 is installed in weight box 20 bottoms; PLC50 carries out logic determines according to the data that LOAD CELLS 40 is sent into, and discharge door 11, variable-frequency motor 32, major loop control system 60 are controlled.The sieve aperture of inclination sieve plate 13 is 10 * 10 mm square holes.
