the coaxial fixed mounting in carousel 1 below have a driving pulley 11, driving pulley 11's right side is equipped with one and the same driven pulleys 12 of its diameter, be connected with belt 13 between driving pulley 11 and the driven pulleys 12, the epaxial circumference equipartition of driven pulleys 12 has a plurality of horizontally arc poles 14, the quantity of arc pole 14 is the same with the quantity of telescopic link, arc pole 14 is opposite with driven pulleys 12's the turning to by the trend of inner to the outer end, 8 lower extremes of riser be fixed with a

second montant

15, 14 protruding side and the contact of second montant 15 of arc pole when driven pulleys 12 rotate to can promote riser 8 to the left side.

The vertical plate 8 on wear to be equipped with the horizontal pole 16 of a left right direction, horizontal pole 16 is fixed to be set up and vertical plate 8 can be on horizontal pole 16 horizontal slip, extension spring 9 suit is on horizontal pole 16.

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.

A straight gear 18 is coaxially and fixedly arranged below the rotary table 1, an incomplete gear 19 is meshed with the right side of the straight gear 18, and the incomplete gear 19 rotates to drive the rotary table 1 to rotate intermittently.

In order to enable the vertical plate 8 to smoothly push the inner rod 3 towards the right side, the side wall of one end, close to the rotary table 1, of each outer rod 2 is provided with a small-diameter air hole 20 communicated with the inner cavity of the outer rod; when the inner rod 3 retracts into the outer rod 2, air in the outer rod 2 is slowly exhausted through the air hole 20, and the inner rod 3 can be decelerated and buffered.

The incomplete gear 19 of the invention is driven by a motor, and a speed reducing device can be arranged between the motor and the incomplete gear 19 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 motor, a worker places a hat to be pressed on the U-shaped brackets 4 on the front side, the right side and the rear side, then the motor is started, the motor drives the incomplete gear 19 to rotate, the incomplete gear 19 is meshed with the straight gear 18 to drive the rotary table 1 and the driving pulley 11 to synchronously rotate anticlockwise, the driving pulley 11 drives the driven pulley 12 to rotate through the belt 13, the driven pulley 12 drives the arc-shaped rods 14 to rotate, the rotating speeds of the arc-shaped rods 14 and the rotary table 1 are the same because the diameters of the two pulleys are the same, and the incomplete gear 19 is meshed with the straight gear 18 each time to drive the rotary table 1 and the arc-shaped rods 14 to rotate by 90 degrees; when the telescopic rod rotates 90 degrees to the leftmost position, the U-shaped bracket 4 at the outer end of the telescopic rod is positioned between the upper die 6 and the lower die 7, the arc-shaped rod 14 pushes the vertical plate 8 to the leftmost position, the vertical plate 8 pushes the first vertical rod 10 to the rightmost position, the vertical plate 8 pushes the first vertical rod 10 to the right under the action of the tension spring 9, therefore, the inner rod 3 moves rightwards to retract into the outer rod 2 under the action of the pressure spring 5, the U-shaped bracket 4 is drawn out from the lower part of the cap, the ejector rod 17 can prop the cap to prevent the cap from moving rightwards along with the U-shaped bracket 4, the cap falls on the lower die 7 after the U-shaped bracket 4 is drawn out, and the resistance of the air in the outer rod 2 when being discharged from the air hole 20 can slow down the rightwards moving speed of the inner rod 3, so that the U-shaped bracket 4 is stably drawn out; in addition, because the incomplete gear 19 is meshed with the straight gear 18 at this time, the turntable 1 and the arc-shaped rod 14 are not rotated, the upper die 6 moves downwards to press in the period, 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 incomplete gear 19 is meshed with the straight gear 18 again, the rotary table 1 and the arc-shaped rod 14 rotate again, after the telescopic rod on the left side rotates, the second vertical rod 15 on the telescopic rod on the left side rotates out from the left side of the vertical plate 8, and the inner rod 3 extends out of the outer rod 2 under the action of the pressure spring 5; after the turntable 1 rotates 90 degrees, the U-shaped bracket 4 at the rear side rotates to the position between the upper die 6 and the lower die 7, meanwhile, the next arc-shaped rod 14 rotates 90 degrees to push the vertical plate 8 to the leftmost side again and cross the second vertical rod 15, the U-shaped bracket 4 is drawn out, the upper die 6 and the lower die 7 are pressed, and when the empty U-shaped bracket 4 rotates to the front side or the right side, a worker upwards feeds materials, so that the cycle is performed.

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.
