Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 shows a schematic structural diagram of an embodiment of the present invention, and fig. 2 shows a partial schematic structural diagram of an embodiment of the present invention; fig. 3 is a schematic view of the present invention attached to a pull-up. As shown in fig. 1-3, the present invention provides an automatic tightness adjusting device of a cloth spreading machine, wherein the automatic tightness adjusting device 2 is arranged below a cloth spreading roller of a cloth spreading device 1 of the cloth spreading machine and above a cutter device 3, a transmission assembly comprises a pair of small gears 204 and large gears 203 which are in meshing transmission, the small gears 203 are fixed at the extending shaft ends of a rotary sensor 202, and the rotary sensor 202 is fixed on a connecting rod 101 of the cloth spreading device 1 through a fixed seat 201. The bull gear 204 is fixed on the left side plate 103 of the cloth spreading device 1 through a gear shaft, a tightness adjusting pipe 207 is arranged below the bull gear 204, and the tightness adjusting pipe 207 is respectively fixed on the end surface below the bull gear 204 and the right side plate 102 of the cloth spreading device 1 through a left tightness adjusting pipe arm 206 and a right tightness adjusting pipe arm 208. The slack adjuster tube 207 is a carbon fiber tube.
When the cloth passes through the automatic tightness adjusting device 2, the cloth passes under the tightness adjusting pipe 207 shown in fig. 2, so that the tightness adjusting pipe 207 swings to drive the large gear 204 to rotate, the large gear 204 is meshed with the small gear 203, and the small gear 203 is connected with a rotary sensor 202, so that the process of converting the swinging amount of the tightness adjusting pipe 207 into the rotating amount is completed.
The rotation scale of the rotation sensor 202 is correspondingly converted into voltage to be output, the output voltage is fed back to a control module of the cloth paving machine, the control module carries out angle data conversion, the minimum voltage value corresponds to 0 degree, and the maximum voltage value corresponds to 60 degrees. During the operation of the cloth spreader, the swing amount of the dancer tube 207 is converted into angle data. In the embodiment, the control module sets the looseness value of the cloth at 0-20 degrees, the normal range value of the cloth at 21-39 degrees and the tightness value of the cloth at 40-60 degrees. And after receiving the voltage feedback quantity, the control module converts the voltage feedback quantity to obtain angle data and judges the tightness of the cloth.
The control module converts to obtain the current supported angle value of the cloth, and the control module does not perform tightness adjustment within the set angle of 21-39 degrees.
When the cloth is over-tight, the tightness adjusting pipe 207 above the cloth is lifted, the tightness adjusting pipe 207 moves circularly along the fulcrum of the large gear 204 to drive the large gear 204 to rotate anticlockwise, the large gear 204 drives the small gear 203 to rotate clockwise, so that the output voltage is increased, the control module converts the current supported angle value of the cloth to be within 40-60 degrees, the cloth is judged to be in a tight state, and the speed is gradually corrected at set time intervals. If the current cloth feeding speed is 10m/min, the current speed is subjected to speed increasing correction every 200ms, wherein the speed is 10.1m/min, 10.2m/min and … …, until the angle value is restored to be within the normal range.
On the contrary, when the cloth is loosened, the tightness adjusting pipe 207 drives the large gear 204 to rotate clockwise due to the self weight, the large gear 204 drives the small gear 203 to rotate anticlockwise, so that the output voltage is reduced, the control module converts the current supported angle value of the cloth to be within 0-20 degrees, the cloth is judged to be in the loosening state, and the speed is gradually reduced and corrected at set time intervals. If the current cloth feeding speed is 10m/min, the current speed is subjected to speed decreasing correction every 200ms, wherein the speed decreasing correction is 9.9m/min, 9.8m/min and … … until the angle value is restored to be within the normal range.
The control module of the invention is a P L C control module of the cloth paving machine, which is used for scanning the angle value once per period, judging the tightness state of the cloth in real time, and correcting the current speed in real time to achieve automatic tightness adjustment, wherein the tightness state is judged every 100 ms.
