Specifically, the movable folding mechanism 6 comprises a driving cylinder 61 and a folding frame 62, the folding frame 62 is connected with a piston shaft of the driving cylinder 61 and can be folded or unfolded under the driving of the driving cylinder 61, and the driving cylinder 61 is electrically connected with the control system 7; the control system 7 drives the folding frame 62 to fold and fold through the driving cylinder 61, and meanwhile, the control system 7 drives the adjusting roller way 3 to move downwards through the lifting mechanism 5 so as to reduce the distance between the acceleration roller way 1 and the conveying roller way 2; the control system 7 drives and controls the folding frame 62 to unfold through the driving cylinder 61, and simultaneously, the control system 7 drives the adjusting roller bed 3 to move upwards through the lifting mechanism 5, so that the adjusting roller bed 3 is flush with the conveying surfaces of the conveying roller beds 2 and the accelerating roller bed 1 on the two sides.
After the gypsum board is spread and formed, in the conveying process, the single boards are generally sequentially conveyed, in order to improve the drying efficiency, the gypsum board is generally distributed into a group of two parallel boards by a distribution bridge and enters a drying chamber of a dryer to be dried, however, after the gypsum board is distributed by the distribution bridge, the distance between the gypsum boards can be changed, the distance between the gypsum boards can be increased after the gypsum board passes through the distribution bridge, and when the gypsum board is dried, the distance between the gypsum boards is not too large or too narrow, otherwise, the quality of the dried board can be influenced.
The main effect of the acceleration roller way 1 that this embodiment set up is that the gypsum board interval is adjusted to preliminary chasing the board, and control system 7 adjusts and controls the conveying speed of acceleration roller way 1 according to the feedback speed information of first encoder to reduce the gypsum board interval. The driving mechanism of the acceleration roller way adopts a variable frequency motor, and the control system 7 continuously adjusts the output frequency of the variable frequency motor to adjust the conveying speed according to the length and the real-time conveying speed of the acceleration roller way, so that the distance between adjacent gypsum boards is adjusted.
The gypsum board that just accomplishes interval adjustment through the preliminary adjustment of roll table 1 with higher speed directly sends into the rollgang, control system 7 regulates and control the conveying speed of rollgang 2 according to the feedback speed information of second encoder, and each layer rollgang 2's transmission speed diverse in the gypsum board drying chamber, and the concrete condition is according to every layer and advances the board order and decide, and the transmission speed of the rollgang 2 at the dry layer place of the board that advances is greater than the transmission speed of the rollgang 2 at the dry layer place of advanced board.
Because the drying chamber has a lot of layers, the material loading is in proper order layer by layer, there is the time difference in the time that different layers of gypsum board get into the drying chamber, and the ply conveyor speed that back got into is some big to catch up with the gypsum board of preceding ply, like this, finally stop on the same longitudinal position between the different layers of gypsum board, can not influence drying efficiency because of the straggly.
After the distance between the gypsum boards is adjusted by the accelerating roller way 1, the following three board states mainly exist:
normal transport state, after the adjustment with higher speed of rollgang 1, then show that the board interval meets the requirements, the gypsum board need not readjustment, can directly receive the drying in the drying chamber that sends into the desiccator via rollgang 2, and at this moment, adjustment rollgang 3 is less than the both sides transmission plane height of rollgang 1 and rollgang 2 with higher speed, and adjustment rollgang 3, curved bar guiding mechanism 4, elevating system 5 and activity folding mechanism 6 are all not worked.
If the distance between the plasterboards is too far, the accelerating roller way 1 cannot sufficiently track the plasterboards and still needs to track the plasterboards, and then the roller way 3, the curved bar adjusting mechanism 4, the lifting mechanism 5 and the movable folding mechanism 6 need to be adjusted to be in a working state so as to continuously track the plasterboards, so that the distance between the adjacent plasterboards meets the production requirement.
When the distance between the plates is too close, the acceleration roller way 1 overtakes the plates excessively, and the interval between the plates needs to be increased, the roller way 3, the curved rod adjusting mechanism 4, the lifting mechanism 5 and the movable folding mechanism 6 need to be adjusted to be in a working state, so that the distance between the gypsum plates is increased.
The tail part of the acceleration roller way 1 is provided with a photoelectric detection unit 8 and a distance measurement unit 9, and the photoelectric detection unit 8 and the distance measurement unit 9 are respectively connected with a control system 7; for the states of too close and too far plate distance, the specific detection and adjustment mode provided by the embodiment is as follows:
a distance standard value is set in the control system 7, the distance standard value is the length of a gypsum board, the control system 7 judges and adjusts the space state of the board on the roller way 3 according to the signal change of the photoelectric detection unit 8 and the distance measurement structure of the distance measurement unit 9, and the control system 7 regulates and controls the working state of the curved bar adjusting mechanism 4 according to the judged space state of the board.
Specifically, photoelectric detection unit 8 detects rollgang face, can take place signal change when gypsum board face and gypsum board tip edge, and the signal change that corresponds becomes: when the surface of the gypsum board is detected to be at a high level, the edge of the end part of the gypsum board is detected, a signal can jump from the high level to a low level, and no signal exists when a gypsum board conveying roller way is detected.
The control system 7 judges the gypsum board transportation state according to the detection signal change condition of the photoelectric detection unit 8, if the measurement distance of the distance measurement unit 9 does not reach a distance standard value, the signal of the photoelectric detection unit 8 changes at least once, it indicates that the adjacent gypsum boards on the roller conveyor are too close to each other to generate the board folding condition, and the board shifting adjustment is needed.
A distance standard value corresponding to no signal of the photoelectric detection unit 8 is arranged in the control system 7, and if the measurement distance of the distance measurement unit 9 corresponding to no signal of the photoelectric detection unit 8 exceeds the distance standard value, the condition that the distance between adjacent gypsum boards is too far on the conveying roller way is indicated, and board tracking adjustment is needed.
