Description

[0002] After the YB95 packaging machine stops working every day, the equipment is powered off and the positive pressure air is cut off, and the machine is started only when the positive pressure air is turned on the next day. Since the large transparent paper clamp is driven by the air cylinder to clamp the large transparent paper, the clamping force of the air cylinder is not enough after the positive pressure air is cut off.

The damaged large transparent paper is peeled off by the operator in the morning shift the next day, which causes the waste of materials and labor, and may also cause the damaged large transparent paper to flow to the next process, thereby causing product quality problems.

The two sliding shafts 17 are used for mounting the bottom sliding seat 4, so that the bottom sliding seat 4 can slide on the "U"-shaped seat body 15.

[0028] Preferably, in order to control the displacement amount of the transparent paper paper holder, preferably a limiting bolt 18 is threadedly connected to each of the two end plates of the "U"-shaped seat body 15. The limiting bolt 18 can block the bottom sliding seat 4, and when the positioning shaft assembly 6 is connected with the transparent paper paper holder, the displacement amount of the transparent paper paper holder is controlled by limiting the position of the bottom sliding seat 4.

The air cylinder 5 is used for pushing the connecting rod 7, so that the limiting head 28 on the positioning shaft 26 is separated from the limiting groove on the transparent paper clamp. The connecting bottom plate 24 is used for fixedly connecting with the bottom slide 4.

[0032] Further, the lateral support 30 is fixedly installed on one side of the upper slide 22, the magnet base 31 is fixedly provided with a screw rod on one side, the magnet base 31 is threadedly connected with the lateral support 30 through the screw rod thereon, and the magnet 32 is fixedly arranged on the other side of the magnet base 31.

[0033] The working principle of the device is as follows: during installation, the height position of the positioning shaft 26 is adjusted through the cooperation of the lateral adjusting support 2 and the first long slot 10 on the longitudinal adjusting mounting plate 1, the horizontal position is adjusted through the cooperation of the horizontal sliding seat 3 and the second long slot 14 on the lateral adjusting support 2, and after the magnet 32 is adsorbed with the knob support on the transparent paper clamp, it is ensured that the limiting head 28 at the end of the positioning shaft 26 is opposite to the position of the limiting groove on the transparent paper clamp, and the limiting head 28 can be accurately inserted into the limiting groove. After the positions are adjusted, the screws are fixed, so that the positions of the lateral adjusting support 2 and the horizontal sliding seat 3 are no longer changed.

[0034] During work, the magnet 32 is always adsorbed with the knob support on the transparent paper clamp, when the device is powered off and the positive pressure air is cut off, the transparent paper clamp will immediately start to retreat, the device moves synchronously with the transparent paper clamp, and at the same time, the air cylinder 5 loses the air pressure, the telescopic shaft on the air cylinder 5 loses the thrust, and under the elastic force of the spring 27, the positioning shaft 26 is pushed to move towards the limiting groove on the transparent paper clamp, so that the limiting head 28 at the end of the positioning shaft 26 is inserted into the limiting groove. When the bottom slide 4 contacts the limiting screw 18, the movement is stopped. Since the limiting head 28 is inserted into the limiting groove, the positioning shaft 26 stops moving, so that the transparent paper clamp also stops retreating, thereby ensuring that the transparent paper clamp still has the clamping force on the transparent paper, so that the transparent paper cannot fall off. In this way, the staff does not need to deal with the transparent paper the next day, not only the labor cost is saved, but also the problem of resource waste is solved. There is no defective transparent paper flowing into the subsequent process, and the product quality is ensured.

[0035] When the circuit and gas circuit are recovered the next day, the cylinder 5 works, the telescopic shaft of the cylinder 5 pushes the connecting rod 7, the connecting rod 7 moves with the positioning shaft 26, the positioning shaft 26 compresses the spring 27, and the limiting head 28 is separated from the limiting groove, so that the transparent paper clamp paper device returns to normal work.

[0036] The above detailed the structure, features and effects of the present application according to the embodiments shown in the drawings, the above-mentioned is only the preferred embodiment of the present application, but the present application is not limited to the implementation range shown in the drawing, any change or modification made according to the concept of the present application, or the equivalent embodiment of equivalent change, still within the scope of the present application, should be within the scope of the present application.
