[0033] The present invention provides the following embodiments

[0037] The beneficial effects of the above technical solution are:

[0038] The conveying mechanism is used to convey metric plates 3 or imperial plates. The metric and imperial plate positioning mechanism can automatically switch to the metric plate stop photoelectric 9 or the imperial plate stop photoelectric 8. Both the metric plate stop photoelectric 9 and the imperial plate stop photoelectric 8 can automatically control the start and stop of the conveying mechanism. The metric plate stop photoelectric 9 is used to automatically control the position of the plate discharge roller before the metric plate 3 enters the dryer. The imperial plate stop photoelectric 8 is used to automatically control the position of the plate discharge roller before the imperial plate enters the dryer. The setting of the metric and imperial plate positioning mechanism does not require manual replacement of the metric plate stop photoelectric 9 or the imperial plate stop photoelectric 8, which saves time and effort. Avoid errors in the installation position of the metric plate stop photoelectric 9 or the imperial plate stop photoelectric 8 during manual replacement, and solve the above-mentioned problem that the current position adjustment device has only one stop photoelectric, so that when the product is changed, one person is required to keep an eye on the stop position of the plate, and the other adjustment person needs to loosen the fixing screws of the stop photoelectric rack first, and then communicate and adjust several times before it can stop at the appropriate position. In addition, during the adjustment period, the plate will have some edges overfired due to inappropriate position entering the dryer, and need to be removed, which leads to the technical problem that product change consumes a lot of manpower and material resources and increases costs.

[0042] The beneficial effects of the above technical solution are:

[0043] When the motor 2 is working, it can drive the left rotating shaft 23 to rotate, and the left rotating shaft 23 drives the left sprocket to rotate, and the left sprocket drives the remaining sprockets to rotate through the chain, thereby driving the remaining rotating shafts 23 to rotate, so that several rotating shafts 23 rotate synchronously, and the rotating shaft 23 drives the conveying roller 2 to rotate, thereby completing the conveying of metric plates 3 or imperial plates;

[0044] The switching switch 5 is used to switch the imperial plate stop photoelectric 8 or the metric plate stop photoelectric 9 to work, so that the imperial plate stop photoelectric 8 or the metric plate stop photoelectric 9 can work independently of each other and cannot work at the same time. When conveying metric plates, the metric plate stop photoelectric 9 is controlled to work. When conveying imperial plates, the switching switch 5 is switched to the imperial plate stop photoelectric 8. After the metric plate stop photoelectric 9 detects that the metric plate 3 reaches the plate outlet roller position in front of the dryer, the metric plate stop photoelectric 9 controls the motor 24 to stop working through the controller, so that the metric plate 3 is stationary. After the imperial plate stop photoelectric 8 detects that the imperial plate reaches the plate outlet roller position in front of the dryer, the imperial plate stop photoelectric 8 controls the motor 24 to stop working through the controller, so that the imperial plate is stationary.

The rotation directions of the guide blocks 12 on the front and rear sides are both right, and a spring rod 13 is fixedly provided between the guide blocks 12 and the base blocks 1.

[0050] The beneficial effects of the above technical solution are:

[0051] If the weight of the metric plate or imperial plate being transported changes, its size will also change, and the weight will drive the rotating shaft 23 to move up and down. When the rotating shaft 23 moves up and down, it drives the support block 15 to move up and down. The support block 15 drives the support block 2 16 to move up and down. The support block 2 16 drives the connecting block 17 to move up and down. When the connecting block 17 moves up and down, it drives the sealing plate 19 to slide up and down along the sealing cavity 18, thereby changing the air pressure in the sealing cavity 18. The air pressure detector 20 is used to detect the air pressure in the sealing cavity 18. The sealing arrangement of the sealing cavity 18 is used to achieve air shock absorption for the sealing plate 19. When the support block 15 moves up and down, it can drive the rack 14 to move up and down. The rack 14 drives the gear 26 to rotate. The gear 26 drives the rack 2 to move up and down. The rack 2 drives the mounting block 4 to move up and down. The mounting block 4 drives the imperial plate stop photoelectric 8 or the metric plate stop photoelectric 9 to move up and down through the mounting block 2 6 and the mounting block 3 7.

[0052] When the weight of the metric plate 3 or the imperial plate changes, its size will also change. When it rolls along the conveying roller 2 and passes the guide block 12, it drives the guide block 12 to rotate and the spring rod 13 is compressed, so that the length and width of the metric plate 3 or the imperial plate can be indirectly detected, and the power pump 21 works to supply or deliver air to the sealed chamber 18 through the passage 22, thereby further accurately controlling the up and down moving distance of the imperial plate stop photoelectric 8 or the metric plate stop photoelectric 9.
