the right side of the vertical plate 8 is connected with a pull rope 12, the right side of the vertical plate 8 is provided with a horizontal winding roll 13, the right end of the pull rope 12 is fixed on the winding roll 13, a first gear 14 is coaxially and fixedly connected above the winding roll 13, a second gear 15 is coaxially and fixedly connected below the rotary table 1, an incomplete gear 16 is arranged between the first gear 14 and the second gear 15, and the incomplete gear 16 can be alternately meshed with the first gear 14 and the second gear 15.

The riser 8 on wear to be equipped with the horizontal pole 10 of a left right direction, horizontal pole 100 is fixed to be set up and riser 8 can slide about on horizontal pole 10, a second pressure spring 11 that can promote it left is installed on riser 8 right side.

The outer end of each outer rod 2 is fixedly provided with an ejector rod 17 which is positioned above the inner rod 3 and is parallel to the inner rod 3.

The incomplete gear 16 of the invention is driven by a stepping motor, and a speed reducing device can be arranged between the stepping motor and the incomplete gear 16 according to the requirement; the following description will be made on the operation process with the number of the telescopic rods being 4.

When the device works, the front side or the right side is a charging position, and the left side is a pressing position; before starting the stepping motor, a worker places a hat to be pressed on the U-shaped bracket 4 on the right side and the rear side, then the stepping motor is started, the stepping motor drives the incomplete gear 16 to rotate for a circle each time, the incomplete gear 16 is firstly meshed with the second gear 15 to drive the turntable 1 to rotate 90 degrees anticlockwise, the U-shaped bracket 4 on the rear side rotates to a position between the upper die 6 and the lower die 7, the vertical rod 9 on the inner rod 3 of the telescopic rod is positioned on the right side of the vertical plate 8, at the moment, the incomplete gear 16 is meshed with the second gear 15, the turntable 1 stops rotating, the incomplete gear 16 continuously rotates to be meshed with the first gear 14 to drive the winding roll 13 to rotate, the winding roll 13 winds the pull rope 12 to pull the vertical plate 8 to move to the right side against the action of the second pressure spring 11, the vertical plate 8 pushes the inner rod 3 to move to the right against the action of the first pressure spring, the top rod 17 can support the hat to prevent the hat from moving rightwards along with the U-shaped bracket 4, the hat falls on the lower die 7 after the U-shaped bracket 4 is drawn out, then the stepping motor stops rotating, the upper die 6 moves downwards to be pressed during the stop period of the stepping motor, the upper die 6 moves upwards after the pressing is finished, and the hat is taken out in the process of moving upwards the upper die 6.

When the stepping motor rotates again, the incomplete gear 16 is meshed with the first gear 14, the vertical plate 8 moves leftwards under the action of the second pressure spring 11, the winding roll 13 rotates reversely to release the pull rope 12, the incomplete gear 16 continues to rotate and is meshed with the second gear 15 to drive the rotation to rotate for 90 degrees, the next U-shaped bracket 4 rotates to a position between the lower die 7 and the upper die 6, and the U-shaped bracket 4 is drawn out from the lower part of the hat when the incomplete gear 16 is meshed with the first gear 14 again to finish feeding; the worker loads the material upward when the empty U-shaped bracket 4 is rotated to the right.

The invention can be matched with an automatic discharging device so as to further improve the working efficiency and the safety, for example, the lower die 7 is overturned and discharged after being pressed.

The loading position of the invention is not between the moulds, and the simple unloading can be quickly finished in the process of lifting the upper mould 6, thereby greatly reducing the probability of the worker being crushed; in addition, the device has the advantages that due to the fact that the plurality of U-shaped brackets 4 exist, the pressing work cannot be interrupted when workers pause charging in a short time, and the workers can only load all the vacant U-shaped brackets 4 subsequently, so that the workers can have a short rest and adjust in continuous repeated work.
