Abstract
The invention discloses a system for automatically control the thickness of gypsum board forming slurry. The system comprises a sensing and measuring part, a central processing part and a control part, wherein, the sensing and measuring part is used for on-line-detecting the thickness of slurry on a gypsum board workbench and sending a detection signal to the central processing part; the central processing part is used for processing the detection signal, converting the detection signal to a control signal and sending the control signal to the control part; and the control part adjusts the thickness of the slurry according to the control on a foaming agent regulating pump by the control signal. The automatic method replaces the prior manual work, thus reducing the labor capacity, more accurately and stably controlling the thickness of the slurry in time, and greatly improving the product qualification rate and the appearance quality of products.
Description
Technical field
The present invention relates to a kind of control system that is used to control molding mass of gypsum board thickness.
Background technology
Existing slip control method is for manually seeing the limit, and the post changes the thickness of slip by the operation host computer when slip is too much or very few.This method not only wastes time and energy, and needs to intervene manually, follows the trail of slowly, is not easy to keep stable for a long time; And if the employee has carelessness slightly, will produce substandard product, influenced the qualification rate and the outward appearance of product.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of automatic gauge control system of molding mass of gypsum board, can control molding mass of gypsum board thickness automatically.
A kind of automatic gauge control system of molding mass of gypsum board of the present invention comprises: sensing measurement portion, central processing department and control part, wherein,
Described sensing measurement portion is used for the thickness of online detection plasterboard workbench slip, and detection signal is transferred to described central processing department;
Described central processing department is handled described detection signal, passes to described control part after converting control signal to;
Described control part is regulated pump according to control signal control blowing agent the thickness of slip is regulated;
Wherein, described sensing handling part is an infrared distance sensor, and described central processing department is a Programmable Logic Controller, and described control part is a frequency converter, and it is blowing agent stoste screw pump that described blowing agent is regulated pump;
Described distance measuring sensor is arranged on the position of the upper surface of the slip of distance between last mutual facial tissue and following mutual facial tissue, and distance measuring sensor is transferred to Programmable Logic Controller with detected thickness signal; Programmable Logic Controller converts control signal to after detection signal is handled, and passes to frequency converter again; Frequency converter drive screw pump is regulated the output quantity of foaming stock solution to foam maker, thereby with after water, paper pulp, gesso mix in mixer, enters into the slip platform, thereby reach the thickness of adjusting slip.
The present invention has substituted original limit of manually seeing by automated method, reduced employee's amount of labour, more promptly and accurately stably controlled simultaneously the thickness of slip, product percent of pass can improve 0.5%, thereby therefore the annual cost of raw material that can save about 700,000 has extraordinary economic benefit.In addition, because can the online thickness of controlling slip exactly, thereby have also improved the presentation quality of product greatly by the present invention.
Description of drawings
Fig. 1 is a structural representation block diagram of the present invention;
Fig. 2 is a mounting structure schematic diagram of the present invention.
The specific embodiment
As shown in Figure 1, the present invention includes: sensing measurement portion 1, central processing department 2 and control part 3, wherein, sensing measurement portion 1 is used for the thickness of online detection plasterboard workbench slip, and detection signal is transferred to central processing department 2; Central processing department 2 is handled detection signal, passes to control part 3 after converting control signal to; The thickness that control part 3 is regulated 4 pairs of slips of pump according to control signal control blowing agent is regulated.
Above-mentioned sensing measurement portion 1 can infrared distance sensor, also can be other sensor.Central processing department 2 can be realized by PLC (Programmable Logic Controller), in the program of PLC, use PID (ratio, integration, differential are regulated) that the parameter of whole system is regulated, it is more timely, more accurate to guarantee that whole feedback control system is followed the trail of, maintenance more steady.Certainly, also can adopt other controller to realize.Control part 3 is a frequency converter.It can be that blowing agent stoste is regulated pump that blowing agent is regulated pump 4.Fig. 2 is a mounting structure schematic diagram of the present invention.As shown in Figure 2, distance measuring sensor 11 is arranged on the position of the surperficial h rice of the slip of distance between last mutual facial tissue 21 and following mutual facial tissue 22, distance measuring sensor 11 is transferred to PLC controller 12 with detected thickness signal, PLC controller 12 converts control signal to after detection signal is handled, pass to frequency converter 13 again, frequency converter 13 drive screw pumps 14 are regulated the output quantity of foaming stock solution to foam maker 23, thereby after water 24, paper pulp 25, gesso 26 etc. mix in mixer 27, enter into the slip platform, thereby reach the purpose of regulating slip 28 thickness.
Because slip 28 is made up of siccative and wet feed system, siccative requires to remain unchanged substantially in process of production, for reaching the adjusting purpose, can regulate the wet feed in the slip 28, and blowing agent is a main component in the wet feed, therefore regulate blowing agent screw pump 14 with feedback data, adjusting slip 28 what can reach, also remain in the stable number range with regard to having finished the thickness that slip before the plasterboard 29 production line workbench stripper plates 28 is piled up.By the thickness of control slip 28, guaranteed that the situation on spillage or empty limit can not appear in plasterboard 29 production processes edges of boards.Enhance productivity with this, improve the quality of products simultaneously.
