Description
Technical Field
The invention relates to a fixing device, in particular to a photoelectric switch fixing device for packing belts of threshing and redrying tobacco leaves, which is mainly used for improving the position accuracy of packing belts of threshing and redrying finished products.
Background
In recent years, with the gradual improvement of the requirements on the processing quality, processing clients also put higher requirements on the packaging quality of finished tobacco leaves, so that the four packing belts are gradually changed into four packing belts which are uniformly distributed from the original four packing belts which are approximately spaced apart, and the more uniform and better the distribution. The packing position of the packing belt depends on the distribution and the placing position of diffuse reflection type proximity photoelectric switches (hereinafter referred to as photoelectric switches) of the packing belt and the position of the photoelectric switches relative to a packing support of the packing machine. In actual production, the photoelectric switch is usually fixed on the conveying roller rack through a support, the photoelectric switch can move or rotate along the conveying direction of the paper box on an adjusting support, and the position of the packing belt is adjusted by adjusting the relative position of the photoelectric switch on the support, and then the position of the photoelectric switch is fixed. Because threshing and redrying belongs to rough machining enterprises, noisy sounds are generated by various machine movements, and tiny vibrations of different degrees are generated by parts in the surrounding environment due to hydraulic impact caused by the reversing of an electromagnetic valve of a hydraulic packaging mechanism, etc., a photoelectric switch is fixed on a bracket by adopting bolts and nuts, and along with the prolongation of production time, the bolts and nuts can loosen to a certain degree, so that the positioning positions of the photoelectric switch are relatively moved, and a certain error is generated in the positions of packaging belts; even if the stand alone is fixed to the ground, its vibration is relatively reduced, but still exists, which means that the positioning position of the photoelectric switch is changed as soon as the production time is long, resulting in a decrease in packing quality. If the locknut and the bolt are adopted to fix the photoelectric switch, the photoelectric switch is damaged and needs to be replaced, so that great replacement difficulty is caused. In the case of continuous production, the baler is fixed by means of locking wheels, but the position of the baler also slightly fluctuates, so that the overall slight fluctuation of the position of the baling belt is caused, and the quality of the baling belt is affected to a certain extent. When the packer fails and needs to be replaced, a certain time is needed for locating the locating position of the packer, meanwhile, the position of the packer after replacement and the position of the packer before replacement are difficult to be guaranteed to be completely and stably combined, and the quality of the packing belt is also affected to a certain extent.

By establishing a connection between the left and right support surfaces of the left and right support brackets and the frame of the baler, the photoelectric switch can slide along with the tiny displacement variation of the baler in the length direction of the fixed bracket. After the installation position of the packer is fixed, the relative position of the photoelectric switch relative to the packer is kept unchanged. The position of the strapping band on the smoke box can be guaranteed to be fixed relative to the packer. The distance between the packing belts on the smoke box can be fixed by arranging the positions of the clamping boxes on the left supporting frame and the right supporting frame. The 4 baling belts on the smoke box are integrally positioned at the middle position on the smoke box by adjusting the delay time of the action of the baling press in the PLC system. Based on the principle, the accurate control of the position of the packing belt of the smoke box can be realized.
The specific photoelectric switch position self-adjustment principle is as follows:
the position of the packing belt depends on the picking of corresponding photoelectric signals, after delay, the packer is started, the relative positions of the photoelectric switch and the packer are fixed, the position of the packer can be slightly changed correspondingly in the production process, the installation position of the photoelectric tube and the position of the packing support of the packer are related through a movable locking support frame, and aiming at the slightly changed position of the packer, the photoelectric tube can be self-adjusted along with the slightly changed displacement of the packer through the movable locking support frame, and the self-adjustment is realized through a sliding guide groove on an independent fixed support frame. At the same time, the positions of the four photoelectric cells should be fixed, and considering that the packer support is arranged between the second photoelectric switch 5b and the third photoelectric switch 5c, the relative positions of the photoelectric switch and the packer support can be adjusted through the second photoelectric switch 5b, the third photoelectric switch 5c and the related device, then the distance between the first photoelectric switch 5a and the second photoelectric switch 5b can be fixed, and the distance between the third photoelectric switch 5c and the photoelectric switch 5d can be fixed. In order to facilitate timely replacement of the fault packer, a spring force is adopted between a packing support of the packer and a supporting frame of the photoelectric switch for pre-tightening. The photoelectric switch is fixed through the clamping box on the photoelectric switch supporting frame, the clamping box can just clamp the photoelectric switch in the clamping box, the position of the photoelectric switch is prevented from changing, and the clamping box is tightly pressed through spring force.

The left and right supporting frames of the photoelectric switch can slide along the guide grooves between the fixing parts, so that the dynamic stability of the quality of the packing belt is realized;
4. compared with the traditional method of fixing the photoelectric switch by bolts and nuts, the method has the advantages that the position of the photoelectric switch is fixed in a cartridge mode, the position fixing effect of the photoelectric switch is more obvious, and meanwhile, the defect that the quality of a packing belt is affected due to the fact that the diffuse reflection angle of a photoelectric tube is changed due to loosening of the bolts and nuts caused by vibration of a vibration source in the surrounding environment is overcome;
5. when the photoelectric switch fails and needs to be replaced, the replacement time of the photoelectric switch is saved, the replacement time of the failure packer is also saved, the labor force is saved, and the working efficiency is improved.
