However, this detection method is prone to misjudgment and on-site interference, which may cause abnormal shutdown of the equipment and affect production efficiency. Therefore, a mold coil protection mechanism is proposed to address the above problems. Utility Model Content

[0006] Preferably, the detection component includes a sensor contact piece, a position sensor and a sensor mounting seat; the sensor contact piece is connected to one end of the rotating rod, the position sensor is mounted on the sensor mounting seat, and the position sensor is used to detect the position of the sensor contact piece.

[0007] Preferably, the limiting assembly comprises a limiting seat and an adjusting bolt, the limiting seat is fixedly connected to one end of the rotating rod, and the adjusting bolt is connected to a threaded hole of the limiting seat.

[0008] Preferably, it also includes a frame, wherein the upper ends on the left and right sides of the frame are rotatably connected to an upper chain wheel, and the lower ends on the left and right sides of the frame are rotatably connected to a gear sprocket, and each group of the upper chain wheel and the gear sprocket is connected to a mold chain; the extruder is connected to the upper end of the frame, and the product outlet of the extruder is located between the two mold chains.

[0009] Preferably, the two rotating rod mounting seats are connected to the side walls of the frame.

[0010] Preferably, the sensor mounting seat is connected to the side wall of the rack.

[0011] Preferably, one end of the adjusting bolt is in contact with the frame, and the distance between the baffle and the mold chain is changed by adjusting the extended length of the adjusting bolt.

[0013] The beneficial effects of the utility model are as follows: the mold coil protection mechanism is set so that when continuous products are difficult to demold on the mold chain, the products rotate with the mold chain. When the products rotate with the mold chain to between the baffle and the mold chain, the products will squeeze the baffle, so that the sensor contact 4 rotates around the axis center of the rotating rod, the sensor contact and the sensor are close, and the sensor feedback signal causes the rotary blow-fill-seal equipment to alarm and stop, thereby protecting the equipment.
