A vulcanizing device for shortening the vulcanizing time and improving the vulcanizing efficiency according to some embodiments of the present application will be described below with reference to fig. 1 to 2.
The utility model provides a reduce vulcanizer that vulcanization time improves vulcanization efficiency, includes vulcanization system and heating system, heating system includes temperature controller, temperature sensor, super temperature sensor and electromagnetic heating board 1 that sets up in groups, electromagnetic heating board 1 is the multiply wood including hot plate 2, coil panel 3, magnetic stripe board 4, the shielding plate 5 that set gradually.
At present, when a flat vulcanizing machine is adopted to vulcanize rubber products, the flat plate which clamps the vulcanized rubber mold up and down is heated, and heat is conducted to the vulcanized rubber mold to complete the heating vulcanization of the rubber products. When the heat conducting oil is used for heating, the heat conducting oil after external heating flows through the flat plate to conduct heat to the flat plate, but the heating time of the heat conducting oil is longer, and meanwhile, the heat conducting oil pipelines are limited in arrangement in the flat plate, so that the heat transfer speed and uniformity can be influenced. In addition, the current vulcanization temperature range is generally 100-140 ℃, and the highest use temperature of the heat conduction oil used by the flat vulcanizing machine is about 140 ℃, so that the temperature gradient is too small in the heating process, and the heating temperature can be regulated and controlled only by regulating the flow of the heat conduction oil through a proportional valve, thereby having insufficient regulation and control capability.
As shown in fig. 1, when electromagnetic heating is adopted, electromagnetic heating plates 1 are arranged on the upper side and the lower side of a vulcanized rubber mold 12, and the electromagnetic heating plates 1 sequentially comprise a hot plate 2, a coil plate 3, a magnetic strip plate 4 and a shielding plate 5 from inside to outside relative to the vulcanized rubber mold 12; the coil board 3 is equipped with recess 6 towards hot plate 2 one side, is provided with solenoid 7 in the recess 6, recess 6 with solenoid 7 is the heliciform with the central point expansion of coil board 3. After the electromagnetic coil 7 is electrified, the electromagnetic coil 7 generates an alternating magnetic field to act on the hot plate 2, so that the hot plate 2 heats, and the hot plate 2 conducts heat to the vulcanized rubber mold 12 to heat and vulcanize rubber products. When electromagnetic heating is used, the hot plate 2 generates heat by itself instead of heating by an external heating medium, so that heating waiting time is reduced; meanwhile, the heating speed of the electromagnetic heating hot plate 2 is adjustable, the heating speed is higher, the temperature gradient is larger, and the vulcanizing time can be further reduced.
The magnetic strip plates 4 are arranged adjacent to the coil plates 3, a plurality of permanent magnet strips 13 are embedded in one surface of the magnetic strip plates 4 facing the coil plates 3, the permanent magnet strips 13 are distributed in a direction orthogonal to the trend of the electromagnetic coil 7, so that an alternating magnetic field generated by the electromagnetic coil 7 can be further polymerized and lifted and acts on the hot plate 2, and the energy efficiency of electromagnetic heating can be improved.
Considering that the core layer and the outer layer of the rubber product are affected by heat transfer during vulcanization, the temperature of the core layer is lower than the temperature of the outer layer for a long time, so that the temperature uniformity is insufficient, and the temperature uniformity is an important factor affecting the vulcanization efficiency. Therefore, the groove 6 and the electromagnetic coil are divided into a central section 8 and an unfolding section 9, the central section 8 is equivalent to the conventional minimum specification of the vulcanized rubber mold 12, preferably a circular area with the radius of 0.25m taking the central point of the coil plate 3 as the center, the electromagnetic coil 7 and the groove 6 of the central section 8 are in a circular spiral shape, the unfolding section 9 is in a square spiral shape, and the distance between the electromagnetic coils of the central section 8 is smaller than that of the unfolding section 9. The electromagnetic coil 7 and the groove 6 of the central section 8 can improve the heating effect of the corresponding central area of the hot plate 2, thereby improving the temperature of the core layer of the vulcanized rubber mold 12, reducing the temperature difference between the core layer and the outer layer and improving the temperature uniformity. And a circular area with a radius of 0.25m centered on the center point of the coil plate 3 is adopted as the center section 8, which corresponds to the conventional minimum specification of the current rubber vulcanization mold 12 being 0.5m in diameter.
Because the electromagnetic heating power applied to the vulcanizing device is larger, in order to better realize the heating effect, a continuous copper pipe is adopted to replace a common wire to serve as an electromagnetic coil, meanwhile, the high-temperature environment where the copper pipe is located is considered, and cooling water is introduced into the copper pipe to enable the copper pipe to be maintained at a proper working temperature, so that the long-term service life is prolonged.
Further, a first straight hole 10 and a second straight hole 11 are arranged on the side wall of the hot plate 2, the first straight hole 10 is used for placing a temperature sensor, and the second straight hole 11 is used for placing an overtemperature sensor; the tail ends of the first straight hole 10 and the second straight hole 11 are arranged in the region corresponding to the central section 8 of the coil plate 3 inside the hot plate 2, and are preferably arranged in the region 0.2m away from the central point of the hot plate 2, so that the temperature sensor and the overtemperature sensor can more accurately measure the temperature of the central region of the hot plate 2, the core layer temperature of a rubber product can be correspondingly and more accurately regulated, and the vulcanization efficiency is further improved; and the method can timely process when the temperature exceeds the normal vulcanization temperature due to improper operation or abnormal equipment, so that the damage of a die or a device is avoided.
Furthermore, the coil plate 3 and the magnetic strip plate 4 are made of high-temperature resistant insulating materials, so that the formed alternating magnetic field can be ensured to fully act on the hot plate 2.
Furthermore, the groove 6 is formed by CNC processing, the processing accuracy is high, the processing surface is smooth, and the placing effect of the copper pipe can be ensured.
Furthermore, the shielding plate 5 is an aluminum plate, so that the phenomenon that the alternating magnetic field generated by the electromagnetic heating plate 1 diverges and heats the external metal part of the vulcanizing device in the opposite direction to the hot plate 2, thereby causing energy efficiency loss and device damage can be avoided.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
