Description
Technical field
The utility model relates to a kind of rubber hot-air molding sulfuration machine, is specifically related to a kind of hot air circulation mechanism of rubber hot-air molding sulfuration machine.
Background technology
Have higher elasticity, hear resistance, hot strength and the characteristics such as indissolubility in organic solvent after the vulcanization of rubber, therefore common rubber (as rubber overshoes) all can pass through vulcanizing treatment at present.General at present employing rubber vulcanizing machine vulcanizes rubber, and in the production process, rubber (mixing vulcanizing agent in proportion) is placed in the sulfuration cylinder of rubber vulcanizing machine, finishes sulfidation after high-temperature process after a while.In this process, the hot air circulation mechanism work of sulfuration cylinder afterbody, the hot air circulate of blowing in the sulfuration cylinder flows, and makes the temperature basically identical at each position in the sulfuration cylinder, avoid with batch vulcanized article Yin Wendu different and qualitative difference occurs.
In the hot air circulation mechanism of conventional vulcanizer, the output shaft of motor is connected by shaft coupling with the rotating shaft of fan; Because fan is in the hot environment during sulfuration, heat can pass to motor along the rotating shaft of fan, and the temperature of motor is raise, and often causes motor or bearing to break down, and working life also can shorten; And the axle sleeve temperature of fan shaft is also than higher, makes that the sealing ring in the axle sleeve is aging easily, needs often to change, and influences manufacturing schedule.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of improvement of hot air circulation mechanism of rubber hot-air molding sulfuration machine is provided, characteristics simple in structure, not fragile, long working life that this hot air circulation mechanism should have.
For realizing above purpose, the utility model has adopted following technical scheme:
The hot air circulation mechanism of rubber hot-air molding sulfuration machine comprises fan that is arranged on sulfuration cylinder inner chamber afterbody and the motor that drives this fan; The rotating shaft of described fan is installed in the large shaft sleeve, and this large shaft sleeve is fixed on the outer wall of sulfuration cylinder afterbody, and its axis horizontal is arranged and be coaxial with described sulfuration cylinder; It is characterized in that: adopt belt transmission between the rotating shaft of described fan and the output shaft of described motor.
Be shaped on a circle in the tube wall of described large shaft sleeve and be used for the cavity of cooling fan rotating shaft, this cavity disposes a water inlet and delivery port and respective line to form the circulation canal of cooling water.
The beneficial effects of the utility model are: in the utility model, adopt belt transmission between the rotating shaft of fan and the output shaft of motor, completely cut off the heat transmission between fan shaft and the motor output shaft, avoided motor to damage, guaranteed the working life of motor because temperature is too high.In addition, large shaft sleeve in the utility model is shaped on cavity, cooperate corresponding pipeline that cooling water is circulated, rotating shaft and large shaft sleeve self to fan cool, make other parts such as bearing in the axle sleeve and sealing ring be operated in the suitable temperature range, not fragile, need not frequent replacing, guarantee normally carrying out of production process.And improvement part of the present utility model is simple, implements easily, and cost is also lower.
Description of drawings
Fig. 1 is working state schematic representation of the present utility model (being installed in sulfuration cylinder right side).
Fig. 2 is the sectional structure schematic diagram of large shaft sleeve in the utility model.
The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, the hot air circulation mechanism of rubber hot-air molding sulfuration machine described in the utility model comprises fan 2, large shaft sleeve 3 and motor 5.Described large shaft sleeve is fixed on the outer wall on sulfuration cylinder 1 right side (being the right direction of Fig. 1); Described fan is arranged on the inner chamber afterbody of sulfuration cylinder, and the outer wall and the described large shaft sleeve of over cure cylinder passed through in the rotating shaft 7 of this fan to the right in regular turn; Described motor is used for the rotating shaft of drive fan.
As shown in Figure 2, the left end of described large shaft sleeve is shaped on and is used for and sulfuration cylinder flange connecting 10, the axis horizontal of large shaft sleeve arrange and with the axis coaxle of described sulfuration cylinder; The left and right two ends of large shaft sleeve are fixed with left end cap 8, right end cap 18 by screw respectively, and the inner chamber of large shaft sleeve is equipped with copper sheathing 12 that the rotating shaft with described fan is complementary, little axle sleeve 21, spring 20, spacing ring 14 and two bearings 19 (also being complementary with the inner chamber of large shaft sleeve simultaneously) from left to right in regular turn.For the high-temperature steam that prevents to vulcanize in the cylinder enters in the large shaft sleeve, between described copper sheathing and the left end cap, between copper sheathing and the little axle sleeve and be respectively equipped with a sealing ring 11 between little axle sleeve and the spring; Little axle sleeve compresses copper sheathing and sealing ring under the effect of spring, strengthen sealing property.Said structure is all similar with the hot air circulation mechanism of conventional rubber vulcanizing machine, and the equal buyable of each parts obtains, and its assembling mode does not describe in detail.
In order to solve the problem that heat transmission causes motor to damage between fan shaft and the motor, in the utility model, the rotating shaft left end of described fan is fixed with belt wheel 4-1, adopts the band transmission between the output shaft of this belt wheel and described motor.After adopting the band transmission, completely cut off the heat transmission between fan shaft and the motor output shaft, motor can not damage because temperature is too high, has guaranteed its working life.
Simultaneously, for large shaft sleeve is lowered the temperature, avoid its inner parts (particularly bearing and sealing ring) to damage because of operating temperature is too high, in the utility model, be shaped on a circle in the tube wall of described large shaft sleeve and be used for the cavity 15 of cooling fan rotating shaft, this cavity disposes a water inlet 13-1 and delivery port 13-2 and respective line to form the circulation canal (pipeline and water pump are omitted and do not draw among the figure) of cooling water.During work, under the effect of water pump, cooling water circulates in cavity and pipeline, makes the temperature of axle sleeve remain in the OK range.Described cavity adopts conventional preparation method to make moulding, is not described in detail at this.
Also have among the figure, belt 4, packing ring 9 is used to install the fan keyway 6 of fan, is used to install the belt wheel keyway 17 of belt wheel.
