After the conical upper cover 320 and the conical lower housing 321 are tightly closed, the controller starts the electric push rod 220, so that the output end of the electric push rod 220 extends out to the end close to the conical upper cover 320, because the extension tube 221 is fixedly connected with the discharge port at the bottom of the heating tank 20, and the extension tube 221 is fixedly connected with the output end of the electric push rod 220, and because the conical lower hopper 222 is fixedly connected with the end of the extension tube 221 far from the discharge port, the conical lower hopper 222 is driven to extend to the first material receiving port 323 at the top of the conical upper cover 320, when liquid plastic is filled between the conical upper cover 320 and the conical lower housing 321, a small amount of liquid plastic is inevitably filled between the first material receiving port 323 and the conical lower hopper 222.

Solid plastic particles are used as a raw material for manufacturing a storage tank sealing head, the heating tank 20 is used for heating the solid plastic particles and heating the solid plastic particles to a liquid plastic state, when the bottom of the conical lower hopper 222 extends to be attached to the top of the first material receiving port 323, the lifting block 210 is driven to slide downwards through the screw rod sliding table 21, the lifting block 210 is fixedly connected with the top of the extrusion rod 200 so as to drive the extrusion rod 200 to press downwards, liquid plastic is extruded into the interior of the extension tube 221 from the heating tank 20, because the discharge port at the bottom of the heating tank 20 and the conical lower hopper 222 are respectively fixedly connected with two ends of the extension tube 221, the bottom of the conical lower hopper 222 is attached to the first material receiving port 323, and then the liquid plastic in the extension tube 221 is injected into the space between the conical upper cover body 320 and the conical lower shell body 321, the liquid level sensor 224 is used for detecting the liquid level of the liquid plastic overflowing to the conical lower hopper 222, the feeding device is ensured to be within a reasonable value, namely the controller cuts off the power of the screw rod sliding table 21, the lifting block 210 stops pushing the extrusion rod 200, and further the feeding is stopped continuously.

Because the conical upper cover body 320 is fixedly arranged through the top plate 30, and because the size and the axial direction of the conical upper cover body 320 and the conical lower shell body 321 are consistent, when the push plate 311 drives the conical lower shell body 321 to be tightly closed with the conical upper cover body 320, the controller is powered off to lift the air cylinder 310, so that the conical lower shell body 321 is stopped to continuously rise, the check ring 322 plays a sealing role, so that liquid plastic entering between the conical upper cover body 320 and the conical lower shell body 321 cannot flow out, after the conical upper cover body 320 is tightly closed with the conical lower shell body 321, a certain pressure is maintained for a period of time, after cooling, the controller drives the output end of the electric push rod 220 to shrink, and the conical lower hopper 222 is removed.

When the electric push rod 220 drives the conical discharging hopper 222 to contract and withdraw from the first material receiving port 323, because one end of the pull rope 420 is fixedly connected with the mounting frame 223, one end of the pull rope 420 far away from the mounting frame 223 is connected with the reciprocating wheel 421 in a winding manner, so that the unwinding motion of the pull rope 420 is used as a traction force to drive the reciprocating wheel 421 to rotate anticlockwise.

When the reciprocating wheel 421 rotates counterclockwise, because the reciprocating wheel 421 and the rotary table 410 are both sleeved with the rotating shaft, the bottoms of the rotary table 410 and the mounting plate 413 are respectively hinged to two ends of the connecting rod 411, and because the cutter 40 is fixedly connected to the mounting plate 413, the mounting plate 413 is slidably connected to the top plate 30 through the connecting rod 415, and then the connecting rod 411 drives the cutter 40 to slide toward one end close to the first material receiving port 323, so as to cut off the excess part of the storage tank end socket overflowing the top of the first material receiving port 323, thereby achieving the effect of cutting off leftover materials, further making the pressed storage tank end socket not need subsequent trimming, improving the forming speed of the product, improving the manufacturing efficiency, in the initial state, the return spring 414 is in an extended state, when the rotary table 410 rotates counterclockwise, because the inner wall of the rotary table 410 and the gear 422 are both sleeved with the gear 422, the gear 422 is engaged with the rack 412, the rack 412 is slidably connected with the guide rail, and because the inner wall of the rack 412 and one end far away from the mounting plate 413 are respectively fixedly connected to two ends of the return spring 414 The connection is fixed, so that when the rack 412 rotates counterclockwise on the turntable 410, the return spring 414 is changed from an extension state to a tightening state, at this time, a buffering effect is achieved, it is ensured that the cutter 40 slides at a constant speed, thereby ensuring that the cut at the cutting position of the end enclosure is smooth, which is beneficial to improving the forming quality of the end enclosure, after the redundant part of the end enclosure is cut off, the output end of the jacking cylinder 310 is driven by the controller to contract, thereby opening the conical upper cover body 320 and the conical lower shell 321, and then taking out the formed end enclosure, due to the linkage design of the conveying assembly 22 and the traction assembly 42, further, when the conical lower hopper 222 is attached to the first material receiving port 323 each time, the cutter 40 automatically returns from the first material receiving port 323, the returning operation specifically means that when the conical lower hopper 222 extends out to be close to the first material receiving port 323, the pull rope 420 is wound, at this time, the reciprocating wheel 421 rotates clockwise, and the return spring 414 of the rack 412 no longer receives the traction force of the rack 412, the cutting knife 40 automatically extends out of the first material receiving opening 323 to realize cutting when the conical discharging hopper 222 is removed each time.
