The lower hand mold 2 is conveyed by the first conveyor belt 1 to move horizontally with the PVC gloves.

The ejector 3 includes: carousel 4, negative pressure pipe 5, sucking disc 6, control valve 7, negative pressure device 8, drive arrangement 9, position sensor 10, carousel 4 is the circular dish of cavity form to form the carousel that has the negative pressure chamber, carousel 4 is vertical to be set up in the below of hand former 2.

Negative pressure pipe 5 is circular steel pipe or aluminum alloy tube, and it is radial setting along carousel 4, and a plurality of negative pressure pipes 5 are radial setting along the circumference equipartition of carousel 4 on carousel 4, and the one end of negative pressure pipe 5 is fixed on carousel 4 and is communicate with the negative pressure chamber to form the negative pressure in negative pressure pipe 5, and then make sucking disc 6 can adsorb the PVC gloves that the hand touched 2, sucking disc 6 is rubber or plastics sucking disc, helps preventing to damage PVC gloves.

Further, the sucking disc 6 communicates on negative pressure pipe 5, and the suction inlet of sucking disc 6 is towards hand former 2 place side, and when negative pressure pipe 5 rotated to its top along with carousel 4, sucking disc 6 just in time pasted and is covered on hand former 2 to catch the PVC gloves on the hand former 2, keep away from relatively along with hand former 2 and sucking disc 6, the PVC gloves are got rid of.

The control valve 7 is an electromagnetic valve, the control valve 7 is arranged on the negative pressure pipe 5, and the control valve can automatically control the on-off of the negative pressure pipe 5 according to an action signal sent by the position sensor 10. The position sensor 10 is arranged on one side of the rotary disc 4 and used for controlling the opening and closing of the control valve 7. The position sensor 10 is a proximity sensor, when the control valve 7 on the negative pressure pipe 5 and the proximity sensor approach to a set distance, the proximity sensor sends an action signal to switch, the control valve 7 is closed, the negative pressure action of the sucker 6 is cut off, and the PVC gloves on the sucker 6 fall off.

Negative pressure device 8 rotates between the negative pressure chamber of carousel 4 to be connected, negative pressure device 8 is the air exhauster, and its suction opening is connected with trachea 11's one end, and trachea 11's the other end passes through rotary joint 12 to be connected with connecting pipe 13, connecting pipe 13 is fixed and is located and communicate with the negative pressure chamber at carousel 4's quotation center.

The connecting pipe 13 and the supporting pipe 17 are respectively connected in shaft holes on two supporting arms of the turntable supporting frame 18, so that the turntable 4 can rotate on the turntable supporting frame 18 under the driving of the driving device 9.

In another preferred embodiment, two position sensors 10 are respectively arranged on the left side and the right side of the rotary plate 4, so as to prevent one position sensor 10 from being out of order or failure and still ensure the normal operation of the demolding device 3, and the PVC gloves adsorbed on the suction cups 6 can be smoothly separated from the suction cups 6 under the control of the position sensors 10.

Referring to fig. 3, in another preferred embodiment, a filter screen 19 is fixed in the suction port of the suction cup 6, so that the PVC gloves are only sucked at the suction port of the suction cup 6 under the limit of the filter screen 19, so as to prevent the removed PVC gloves from being sucked into the suction cup 6 too much, and avoid the problem that the removed PVC gloves are not easy to automatically separate from the suction cup 6 in the subsequent process because the PVC gloves are very soft and can be sucked into the suction cup 6.

Referring to fig. 4, in another preferred embodiment, a second conveyer belt 20 is arranged below the demolding device 3, the second conveyer belt 20 is horizontally arranged, and the second conveyer belt 20 is positioned right below the suction cups 6, so that the PVC gloves separated from the suction cups 6 fall on the second conveyer belt 20 to be transported away.

With continued reference to fig. 1, the principle of the production device for facilitating the demolding of PVC gloves of the present invention is: when the first conveying belt 1 carries the hand mold 2 to move from left to right, the turntable 4 rotates anticlockwise, namely the rotation direction of the turntable 4 is opposite to the movement direction of the hand mold 2, so that the PVC gloves can be removed more quickly and efficiently. Along with the rotation of the turntable 4, the sucker 6 on the negative pressure pipe 5 is attached to the PVC glove on the hand mold 2, the PVC glove is adsorbed on the sucker 6 under the action of negative pressure, along with the continuous anticlockwise rotation of the turntable 4, the hand mold 2 continues to move rightwards, the PVC glove is gradually removed from the hand mold 2 and continuously rotates downwards along with the sucker 6, and the actions are repeated when the sucker 6 on the other negative pressure pipe 5 rotates to the hand mold 2, so that the PVC glove on the hand mold 2 is continuously removed, and the online continuous operation is realized. When the sucker 6 adsorbing the PVC gloves rotates to the position sensor 10, the position sensor 10 sends an action signal to switch off the control valve 7, the negative pressure action of the sucker 6 is cut off, the PVC gloves on the sucker 6 fall off under the action of self gravity, and the sucker 6 continues to rotate along with the turntable 4 to perform next demoulding operation.

It can be seen that the PVC glove demoulding device takes the circular rotary disc as the main component of the removing device, so that the rotary disc can selectively move opposite to the PVC glove hand mould, and the PVC gloves can be removed more quickly and efficiently. Meanwhile, the PVC gloves can be circularly adsorbed and removed through the matching between the negative pressure sucker on the turntable, the control valve 7 and the position sensor 10, so that the PVC gloves on a production line can be subjected to batch demolding by utilizing a simple and compact design, and the device is convenient to use, low in cost and high in efficiency.

Finally, it should be understood that any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
