Vacuum abnormity alarm device for drying machine

Abstract

The invention relates to the technical field of drying machine alarming, in particular to a drying machine vacuum abnormity alarming device which comprises a shell, a feeding device and a sliding rail, the shell is fixedly installed on the ground, the feeding device is located at the feeding end of the shell, the sliding rail is fixedly installed on the ground, and the feeding device is installed above the sliding rail in a sliding mode. And a plurality of uniformly distributed conveying rollers are rotationally mounted in the shell. When the board lapping phenomenon occurs, the gypsum board on the upper layer abuts against a first trigger switch to control starting of a first alarm, the problem that an alarm cannot be given during board lapping is avoided, through cooperation between a first lock plate and a second lock plate, when the gypsum board transported by the conveying roller has the board lapping phenomenon, the first lock plate and the second lock plate lock the gypsum board which does not make contact with the conveying roller, and therefore the gypsum board is not in contact with the conveying roller. And then through cooperation of the first rotating roller and the second rotating roller, the distance between the gypsum boards which are not overlapped is reduced, the distance between the gypsum boards at the overlapped position is increased, and therefore the phenomenon that the gypsum boards are overlapped is avoided.

[0002] As the core equipment of the gypsum board production line, the operating status of the gypsum board dryer is directly related to the production efficiency of the entire production line and the quality of the final product. During the production and drying process of the gypsum board, if an abnormality occurs, it will lead to an increase in the amount of by-products and an increase in the uncertainty factors of equipment damage. Among them, board abnormality is one of the common faults in the dryer. If this abnormality cannot be discovered and handled in time, it may further cause equipment damage. Although the existing dryer board abnormality detection device can detect the board situation, it still has shortcomings, such as Opening No.: CN105006114A, the dryer internal overlapping board alarm device and the dryer, when in use, if overlapping board phenomenon occurs, the gypsum board will lift the bottom of the baffle, and then use the lever to drive the sensor plate to move the sensor plate and activate the alarm, but if the gypsum board of the overlapping board hits the side wall of the baffle, the baffle cannot be lifted, and the gypsum board of the overlapping board will be blocked at the baffle, and the alarm signal cannot be issued.

[0014] 1. The present invention cooperates between a paddle plate 1 and a trigger switch 1. When the feeding device transports the gypsum board to the inside of the shell, the gypsum board contacts and moves the paddle plate 1, so that the gypsum board enters the inside of the shell. When two gypsum boards overlap, the gypsum board on the upper layer contacts and moves the paddle plate 1. The paddle plate 1 rotates and contacts the trigger switch 1. The trigger switch 1 activates the alarm 1, causing the alarm 1 to sound an alarm and stopping the conveying roller of that layer.

When the gypsum board transported by the conveyor roller overlaps, the gypsum board not in contact with the conveyor roller abuts lock plate 1, and the gypsum board in contact with the conveyor roller abuts and shifts shift plate 2. Motor 2 is started, rack 1 drives lock plate 2 to move downward, lock plate 2 pops out and abuts the gypsum board not in contact with the conveyor roller, and the gypsum board not in contact with the conveyor roller abuts lock plate 1, so that lock plate 1 and lock plate 2 lock the gypsum board not in contact with the conveyor roller. When shift plate 2 returns to its position, the gypsum board not in contact with the conveyor roller is unlocked. If it does not fall above the conveyor roller, it continues to be locked. If it falls above the conveyor roller, the gypsum board is no longer overlapping.

[0016] 3. The present invention cooperates between the rotating roller 1 and the rotating roller 2. When the gypsum board transported by the conveying roller overlaps, the motor 2 is started, and the sliding frame drives the rotating roller 1 and the rotating roller 2 to move upward, the gypsum board above the rotating roller 1 is decelerated to a stagnant state, and the gypsum board above the rotating roller 2 is accelerated, thereby reducing the distance between the gypsum boards that are not overlapped and increasing the distance between the gypsum boards at the overlapped position, thereby eliminating the overlapping phenomenon of the gypsum boards.

At this time, the motor 2 342 is started, the sliding frame 33 drives the rotating roller 1 351 and the rotating roller 2 352 to move upward, the rack 1 32 drives the locking plate 2 321 to move downward, the locking plate 2 321 pops out and abuts the gypsum board not contacted by the conveying roller 113, and the gypsum board not contacted by the conveying roller 113 abuts the locking plate 1 31, so that the leaf spring 312 contracts. At this time, the gypsum board not touched by the conveying roller 113 is locked by the locking plate 1 31 and the locking plate 2 321, the rotating roller 1 351 slows down the gypsum board above to a stagnant state, and the rotating roller 2 352 accelerates the transportation of the gypsum board above, reducing the distance between the gypsum boards and increasing the distance between the gypsum boards at the overlapping parts. When the second shifting plate 311 returns to its position, if the distance between the gypsum boards at the overlapping parts is insufficient, the gypsum board not touched by the conveying roller 113 continues to be overlapped on the next gypsum board. When the next gypsum board resists and shifts the second shifting plate 311, the gypsum board not touched by the conveying roller 113 continues to be locked. If the distance between the gypsum boards at the overlapping parts is sufficient, the gypsum board not touched by the conveying roller 113 is unlocked and falls above the conveying roller 113.

[0045] The working principle and use method of the second embodiment of the present invention are explained in detail below: Under normal conditions, the gypsum board is conveyed to the inside of the outer shell 1 by the feeding device 111, and the gypsum board contacts and moves the paddle plate 21, so that the gypsum board passes through the paddle plate 21 to the inside of the outer shell 1. When two gypsum boards overlap, the gypsum board on the upper layer contacts and moves the paddle plate 21, and the paddle plate 21 rotates and contacts the trigger switch 142, which activates the alarm 22, causing the alarm 22 to sound an alarm and shut down the conveying roller 113 of that layer.
