DETAILED DESCRIPTION

[0024] The utility model discloses an embodiment of the utility model will combine the drawing in the embodiment of the utility model, the technical scheme in the embodiment of the utility model is clearly and completely described, obviously, the described embodiment is only a part of embodiment of the utility model, but is not all the embodiment. Based on the embodiment in the utility model, all other embodiments that the ordinary skill in the art obtains without making the creative labor are within the scope of the utility model protection.

[0025] In the embodiment, by Figures 1-4 Give, an automatic deviation rectifying device for live loop swing door, the utility model includes frame body 2 and pneumatic valve table 3, is provided with pneumatic control assembly 1 on the frame of pneumatic valve table 3, and the side wall of frame body 2 is fixedly installed with mounting spare 4, and the top of mounting spare 4 is fixedly installed with rotary base 5, and the top of rotary base 5 is rotatably connected with carrier roller base 6, and the inside of mounting spare 4 is provided with sliding slot 7, and the bottom of carrier roller base 6 is fixedly connected with sliding block 8, and the top of mounting spare 4 is rotatably connected with air cylinder 9, and the piston rod trunnion of air cylinder 9 is rotatably connected with carrier roller base 6, for driving carrier roller base 6 moves along sliding slot 7, and the inside of mounting spare 4 is fixedly installed with first photoelectric switch 10.

[0026] Pneumatic control assembly 1 includes T type baffle 103 fixedly installed on pneumatic valve table 3, and T type baffle 103 is fixedly installed with gas source two joint spare 102 outside, and the gas inlet of gas source two joint spare 102 is fixedly installed with ball valve 101, and the gas outlet of gas source two joint spare 102 is connected with the gas inlet of electromagnetic reversing valve 106 through air pipe, and pressure gauge ball valve 104 is fixedly installed on the air pipe between gas source two joint spare 102 and electromagnetic reversing valve 106, and electromagnetic reversing valve 106 is provided with muffler 105 outside, and muffler 105 is connected with the exhaust port of air cylinder 9, and the gas outlet of electromagnetic reversing valve 106 is connected with the gas inlet of air cylinder 9.

[0027] The air inlet of the air source two-piece is connected with an external air source (such as an air compressor), when the air path pressure needs to be measured, the pressure gauge ball valve 104 is opened, so that the compressed air enters the pressure gauge through the pressure gauge ball valve, and the pressure gauge can display the current air path pressure value, facilitating the monitoring and adjustment of the working pressure of the pneumatic system, when the pressure does not need to be measured or maintenance is performed, the pressure gauge ball valve is closed, the connection between the pressure gauge and the air path is cut off, the pressure gauge is protected, and gas leakage is prevented, when the cylinder completes the action, the exhaust gas passes through the silencer, and the special structure inside the silencer 105 reduces the flow rate and pressure of the gas, thereby reducing the noise generated during exhaust, making the operation of the pneumatic system more quiet, and reducing noise pollution to the surrounding environment.

[0028] The top of the mounting piece 4 is fixedly connected with a support 11, and the inside of the support 11 is fixedly installed with a plurality of second photoelectric switches 12, the number of which is not less than four.

[0029] The inside of the carrier roller base 6 is rotatably connected with a deviation correction carrier roller 13, the number of the deviation correction carrier roller 13 is even, and every two deviation correction carrier rollers 13 are oppositely distributed.

[0030] The inside of the mounting piece 4 is rotatably connected with a rotating shaft, and the outside of the rotating shaft is fixedly connected with a guide roller 14, which is used to guide the running direction of the strip steel.

[0031] The first photoelectric switch 10, the second photoelectric switch 12 and the pneumatic control assembly 1 are electrically connected with a logic controller.

[0032] Specifically, referring to Figure 1 The left side of the frame body 2 is an operation side, and the right side of the frame body 2 is a transmission side, the two deviation correction carrier rollers 13 are arranged in an “eight” shape along the running direction of the strip steel, the opening faces the running direction of the strip steel, four layers of deviation correction carrier rollers are arranged, the included angle between the central axis of the transmission side deviation correction carrier roller 13 and the advancing direction of the strip steel is equal to the included angle between the central axis of the operation side deviation correction carrier roller 13 and the advancing direction of the strip steel, and the adjustment range of the included angle is 0°-12°.

[0033] Eight diffuse reflection type photoelectric switches (four transmission side photoelectric switches and four operation side photoelectric switches) are symmetrically arranged on both sides of the center line of the unit, which are used to detect the position of the strip steel, when the center line of the strip steel coincides with the center line of the unit, the signals (the number of strip steels blocked) received by the photoelectric switches on both sides are the same, the logic controller determines that the strip steel is in the ideal running position, and the number of installed photoelectric switches is used to adapt to strip steels with different width ranges.

[0034] When the strip steel deviates, the cylinder on the side with less signals from the photoelectric switch is actuated, for example, when the strip steel deviates to the driving side, the number of photoelectric switches blocked on the driving side is greater than that on the operating side, the logic controller determines that the strip steel has deviated to the driving side, at this time, the operating side electromagnetic valve is powered, the electromagnetic valve is reversed, and the cylinder moves in the opposite direction, so that the driving side roller swings, as shown in Fig. Figure 2 The driving side correction roller and the operating side correction roller of the layer form a "I" shape, which pushes the strip steel to move away from the driving side, and realizes correction.

[0035] During correction, the strip steel is subjected to the same side pushing force from the driving side roller and the operating side roller, and finally the lateral force for controlling the automatic correction of the loop is increased, so as to realize the automatic correction of the position of the strip steel, when the strip steel returns to the ideal position, the number of signals received by the second photoelectric switch 12 on both sides is consistent, the logic controller determines that the strip steel has returned to the position coinciding with the center line of the unit, the correction action is ended, the electromagnetic valve is powered off, the correction cylinder is reversely actuated to return to the initial state, the correction roller returns to the "8" shape running state, and the first photoelectric switch 10 is used for detecting the retracted position of the cylinder 9.

[0036] The device can adjust the correction accuracy by adjusting the distance between the photoelectric switches, and can also adjust the action speed of the cylinder by the one-way flow regulating valve arranged outside the cylinder, so as to adapt to the running of the strip steel with different speeds.
