Description

Technical Field

[0001] The utility model belongs to the field of end cap processing equipment, and in particular relates to an assembled forming die for producing PP PE tape wound conical end caps. Background Art

[0002] Head processing equipment is a mechanical equipment specially used to produce heads of various shapes and specifications. These heads are usually used at the ends of pressure vessels, storage tanks, furnaces, heat exchangers and other equipment. They have the function of reducing the cross-sectional area of ​​the container and increasing the rigidity and strength of the container.

[0003] In the prior art, the end caps of storage tanks are usually large in size. When manufacturing the top caps of storage tanks, when manufacturing small caps, the molding method is usually used. However, when manufacturing larger caps, the molding method not only requires huge stamping molds, but also easily causes uneven distribution of PP and PE materials on the surface of the caps during the molding process, leading to structural instability.

[0004] Therefore, an assembled molding die for the production of PP PE tape wrapped conical heads is proposed. By setting a surface rolling uniform feeding structure and a hot melt device, the problem of inconvenient production of large tank heads and structural instability caused by surface unevenness during the preparation process is solved.

When the slider is turned on, the electric cylinder is turned on at the same time, so that the outer walls of the second roller and the fourth roller are always in contact with the right end outer wall of the conical mold, thereby achieving uniform feeding of the right end outer wall of the conical mold.

[0012] Preferably, a heater is fixedly connected to the rear end of the push block, and a plurality of heating tubes are arranged on the heater. The irradiation direction of the heating tubes is toward the right outer wall of the conical mold. When the PE tape moves along a spiral line trajectory on the right outer wall of the conical mold, the heater is turned on so that the heating tubes on the heater perform secondary softening work on the PE tape at the right end of the outer wall of the conical mold, and then the second roller is used to fully press the secondary softened PE tape to ensure that the PE tape is evenly distributed on the right outer wall of the conical mold.

[0013] Preferably, the conical mold is made of iron, which has good thermal conductivity and is convenient for the PE tape to adhere.

When the fourth roller rotates, the PE belt on the outer wall of the fourth roller is driven to feed the outer wall of the right end of the conical mold. Then, the PE belt on the outer wall of the right end of the conical mold is rolled by the second roller. At the same time, the slider is turned on to make the slider slowly slide backward at the upper end of the slide rail. When the slider is turned on, the electric cylinder is turned on at the same time to make the outer walls of the second roller and the fourth roller always fit with the outer wall of the right end of the conical mold, so as to realize the uniform feeding of the outer wall of the right end of the conical mold. By replacing conical molds of different sizes, heads of different sizes and specifications can be prepared, which solves the problem of inconvenience in making heads of large storage tanks.

[0016] 2. Turn on the heater to make the heating tube on the heater perform secondary softening work on the PE tape at the right end of the outer wall of the conical die, and then use the second roller to fully roll the secondary softened PE tape to ensure that the PE tape is evenly distributed on the outer wall of the right end of the conical die, solving the problem of uneven surface material distribution in the preparation process of the head;

[0017] 3. By turning on the flamethrower and making the nozzle on the flamethrower spray flame, the outer wall of the right end of the conical mold can be stably raised, so that when the outer wall of the right end of the conical mold contacts the PE tape, the PE tape can be softened at high temperature, so that the outer wall of the right end of the conical mold can adhere to the PE tape, driving the PE tape to move along the vortex line trajectory on the outer wall of the right end of the conical mold, thereby realizing the preparation of the head.
