Description
Technical field:
The utility model relates to the production equipment-moulding car in a kind of steel cable core conveying belt production line, specifically a kind of correction device for film unwinding trolley.
Background technology:
In the steel cable core conveying belt production line, the moulding car is main production equipment, and the upper and lower film that it will cover on the Steel cord carries out cold moudling in the flat board of colding pressing.The main effect of unwinding trolley is that the flat board of colding pressing is led out and sent into to the upper and lower film that is used for covering Steel cord.To carry out the cold moulding of deciding in order allowing film centering enter to cold pressing in the flat board, to require the center line and the unit central lines of unwinding trolley, all leave identical surplus glue to guarantee the made-up belt both sides.Be subjected to tension and other reason during owing to work, made-up belt often departs from the unit center line, makes the made-up belt width produce deviation, needs to regulate manually correction.
Summary of the invention:
The purpose of this utility model provides a kind of correction device for film unwinding trolley of realizing automatic deviation correction.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of correction device for film unwinding trolley, it comprises the vehicle frame of unwinding trolley, the holder rubber roll tube that film is housed is installed on the vehicle frame, wheel is housed below the vehicle frame, wheel is installed on the power transmission shaft, vehicle frame is provided with servomotor, detect the photoelectric sensor of film side-play amount, according to the executing agency of side-play amount control servomotor motion and comprise the control device of PLC (Programmable Logic Controller), the photosignal of photoelectric sensor is sent into the input module of PLC, the control signal of PLC is sent into servomotor by output module, described executing agency comprises the belt wheel that is installed on the power transmission shaft, and servomotor is connected with belt wheel by being with synchronously.
Because adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, and the control accuracy height is easy to operate, has improved operating efficiency and product quality, has also improved the steel cable core conveying belt automatic degree of production line.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.
By Fig. 1, Fig. 2 as can be known, a kind of correction device for film unwinding trolley, it comprises the vehicle frame 3 of unwinding trolley, the holder rubber roll tube 1 that film 2 is housed is installed on the vehicle frame 3, wheel 5 is housed below the vehicle frame 3, wheel 5 is installed on the power transmission shaft 6, vehicle frame 3 is provided with servomotor 9, detect the photoelectric sensor 4 of film side-play amount, according to the executing agency of side-play amount control servomotor 9 motions and comprise the control device of PLC, the photosignal of photoelectric sensor 4 is sent into the input module of PLC, the control signal of PLC is sent into servomotor 9 by output module, described executing agency comprises the belt wheel 8 that is installed on the power transmission shaft 6, and servomotor 9 is by being with 7 to be connected with belt wheel 8 synchronously.
During the utility model work, photoelectric sensor 4 places the edge of film 2 to be installed on the vehicle frame 3, the real-time input module that detects the left and right sides side-play amount of film 2 and photosignal is sent into PLC, PLC control servomotor 9 starts, by synchronously with 7, belt wheel 8, drive the purpose requirement that vehicle frame 3 move left and right reach correction.
