The thread groove is rotated by rotating the round rod, and the driving block is moved by rotating the thread groove. The driving block moves and drives the rotating sleeve to rotate. The rotating sleeve rotates and drives the fixed sleeve to rotate. The fixed sleeve rotates and drives the rotating rod to rotate. At this time, the rotating rods at the three positions will move toward the center of the fixed sleeve. The movement of the rotating rod drives the positioning rod to move until it contacts the flange group. At this time, the position of the flange group is positioned. The fixed end of the electric push rod is fixedly installed on the front side of the base. The push plate is fixedly installed on the output end of the electric push rod. The push plate is extended by the output end of the electric push rod to push out the bottom flange group. After the output end is retracted, the next flange group will replace the position of the flange group that has been pushed out. The limiting wheel is fixedly installed on the circumferential surface of the round rod. The clamping rod is slidably installed on the right side of the base. The flange group is arranged inside the base. When the round rod is rotated clockwise, the limiting wheel will contact the non-inclined surface of the clamping rod.

The sliding of the flange group will contact the reduction wheel, and the sliding of the flange group is buffered by the reduction wheel.

[0011] According to the above technical solution, the auxiliary device includes an L-shaped frame, a limit block and a moving rod. The L-shaped frame is fixedly installed on the left side of the fixed frame, the limit block is slidably installed on the inner wall of the L-shaped frame, and the moving rod is fixedly installed on the top of the limit block. When the baffle moves, its outer wall will contact the inclined surface of the limit block, so that the limit block moves forward and compresses the No. 3 spring at the same time. When the limit block and the slot are on the same horizontal line, the No. 3 spring is released and drives the limit block to be inserted into the slot, and the baffle is fixed at this time.

[0012] According to the above technical solution, a No. 3 spring is arranged between the limit block and the L-shaped frame, and the limit block is reset by the No. 3 spring.

[0014] The present invention provides an adjustable feeding device for flange cutting, which has the following beneficial effects: (1) The invention places the flange group inside the base by setting up an emptying device, and drives the positioning rod to move through the round rod, driving block, rotating sleeve, fixing sleeve and rotating rod until it contacts the flange group. At this time, the position of the flange group is positioned. In this way, flange groups of different specifications can be quickly and accurately fixed on the feeding device, reducing the time for adjusting and replacing positioning components, thereby improving production efficiency. The bottom flange group is pushed out by the electric push rod and push plate, which can ensure that each flange group is sent out in a predetermined order and position. This is very important for the production process that requires precise control of the feeding order and position. When the round rod is rotated clockwise, the rotation of the limit wheel is restricted by the locking rod, that is, the round rod cannot be reversed. This anti-accidental touch method can improve the safety and stability of the positioning rod after positioning the flange group, ensuring that no accidents will occur due to accidental touch of external force under normal working conditions.

[0015] (2) In the present invention, the flange group is pushed out and enters the slide plate through the setting of the adjusting device. The flange group slides through the inclined surface of the slide plate, and the sliding of the flange group is buffered by the reduction wheel. The baffle plate is moved to the left by rotating the motor and the long rod. The conveying width of the conveyor belt is adjusted by the movement of the baffle plate. By adjusting the width of the conveyor belt, it can adapt to flange groups of different diameters or sizes, thereby improving the flexibility and responsiveness of the production line. The movement of the baffle plate drives the slide plate to move and retracts the movable end of the telescopic rod at the same time. The movement of the slide plate drives the base to move, thereby matching the emptying device and the slide plate to the adjusted width of the conveyor belt.

[0016] (3) This invention, through the setting of the auxiliary device, when the baffle moves, its outer wall will contact the inclined surface of the limit block to complete the fixation of the baffle, which can ensure that the baffle remains fixed after being adjusted to the desired position, and prevent displacement due to vibration, collision or other external forces during operation, thereby ensuring that the width of the conveyor belt remains in the adjusted state, ensuring the stable transportation of the flange group. When adjustment is required, the limit block is disengaged from the slot by moving the rod. At this time, the position of the baffle can be freely adjusted. When the flange group enters the conveyor belt, the guide plate is driven to move by the cylinder. The flange groups scattered on both sides of the conveyor belt are pushed to the center of the conveyor belt by the guide plate, preventing these flange groups from being worn at the junction of the fixed frame and the conveyor belt, and the moving position of the guide plate is limited by the positioning plate.
