At this time, the horizontal transfer section 22 is formed in one to four places depending on the number of times of application of the drug, in Figure 1 shows a state formed so as to be spaced apart in two places for the first, second chemical coating.

Then, the transfer rod 26 is protruded horizontally and trajectory movement in the state inserted in the center of the inner tube (P) which is supplied to each through the inner tube input portion 30, and carries a plurality of inner tubes (P) continuously supplied It is spoken at regular intervals on the chain conveyor 20 so as to make it possible.

In addition, the inner tube injection portion 30 according to the present invention is installed adjacent to the horizontal transfer section 22 of the chain conveyor 20 exposed to the outside of the heating chamber 10, and is fed through the feeder 32 Inner tube (P) is fed onto the transfer rod (26). As shown in FIG. 3, the inner tube injection portion 30 is installed at any one side of the horizontal transfer section 22 formed at two places to supply the inner tube P to each of the inner tube injection portions 30. For details, refer to the following description.

The inner tube injection part 30 is installed on the bottom of the inclined rail 34 and the inclined rail 34 on which the heater 34a is installed on the bottom while preparing the inner pipe P supplied through the feeder 32. The seal 36 is horizontally moved by the operation of the lid 36a to inject the inner tube P onto the transfer rod 26. The inclined rail 34 is provided with a side plate so that the width of the inner tube P can be adjusted according to the length of the inner tube P, and is heated by the heater 34a to be preheated while the inner tube P is aligned. The seal 36 moves forward by the operation of the cylinder 36a and transfers the prepared inner tube P forward one by one to the transfer rod 26 of the chain conveyor 20. At this time, the operation timing of the seal 36 is set such that the inner tube P is correctly supplied on the transfer rod 26 in consideration of the transfer speed of the chain conveyor 20 and the interval between the transfer rods 26.

In addition, the chemical coating unit 40 according to the present invention is located at the bottom of the horizontal transfer section 22 of the chain conveyor 20 exposed to the outside of the heating chamber 20, while being rotated by the driving force of the motor gap adjusting lever ( A pair of chemical supply rollers 44 are installed in the longitudinal direction to be adjusted by the 44a), and the chemical storage unit 46 is accommodated so that the chemicals supply rollers 44 located at the lower portion of the chemical supply rollers 44 are partially locked. . As shown in the drawings, the chemical coating unit 40 is installed at the bottom of the horizontal transfer section 22 formed in two places so as to be exposed to the outside of the heating chamber 10 in the double coating of the chemicals in the first and second times. When the same drug is applied repeatedly, or when the inner tube P applied to the mounting rubber (P) is chemically treated, the first chemical treatment is first performed so that the chemical agent is more closely settled to increase the adhesive force of the rubber bush. When the first chemical treatment is completed, two different chemicals are continuously coated in a manner of secondary chemical treatment of the chemical agent to increase the adhesive force of the rubber bush.

Here, the chemical supply roller 44 is a drug on the outer peripheral surface of the inner tube (P) which is transported by the chain conveyor 20 while the chemical stored in the chemical storage unit 46 is buried in the chemical supply roller 44 when driven by the motor In this case, the drug supply roller 44 is interviewed locally on the inner surface of the inner tube (P) so that the drug is quantitatively applied, thereby preventing excessive consumption of the drug and at the same time preventing application of the drug to unnecessary portions (eg, sides).

And, the chemical supply roller 44 is provided in a pair to be installed in the longitudinal direction to be adjusted by the gap adjusting lever 44a, but if the gap is narrowly adjusted the amount of chemical residue on the outer peripheral surface of the chemical supply roller 44 decreases the inner tube Also, the amount of chemical applied to (P) is also reduced, and if the interval is adjusted widely, the amount of chemical application is increased in contrast to the above. In consideration of the working conditions such as the feed rate and the chemical coating thickness of the inner tube (P), the operator arbitrarily adjusts the gap adjusting lever 44a to control the chemical supply amount.

That is, the inclined member 52 is installed vertically on the vertical transfer section 24 of the chain conveyor 20, wherein the inclined member 52 is adjacent to the end of the transfer rod 26 toward the lower end as shown in FIG. As the trajectory movement of the chain conveyor 20 has the inclined structure to the end of the inner tube (P) in the vertical transfer section 24, the end of the inner tube (P) is slid to the inclined member 52, gradually moving ( 26) It is pushed to the end and released.

In operation, first, when the heater 12 is operated to set the internal temperature of the heating chamber 10 to 40 to 80 degrees, the feeder 32 is operated to align the inner tube P on the inner tube inlet 30. In this case, the inner tube P is preheated by the heater 34a on the inclined rails 34 of the inner tube input portion 30. Subsequently, when the sealing 36 moves forward by the operation of the cylinder 36a and transfers the prepared inner tube P forward one by one and supplies it on the transfer rod 26 of the chain conveyor 20, the chain conveyor 20 As the trajectory is moved, the inner tube (P) is interviewed by the chemical supply roller (44) and the chemical is applied to the outer surface.

Then, the inner tube (P) to which the chemical is applied is transferred to the heating chamber (10) and dried, and then transferred to the outside of the heating chamber (10) and the chemical is secondly applied by the other chemical supply roller (44). The inner tube (P) coated with chemicals is transferred to the inside of the heating chamber (10) again and reaches the inner tube discharge part (50) while being dried and is separated from the storage rod (26) by the inclined member (52). 54) are towels.

As such, the inner tube P is zigzag-transmitted into and out of the heating chamber 10 by the chain conveyor 20 installed in the longitudinal direction, thereby uniformly carrying out the chemical coating and drying processes throughout the first and second stages. And the space utilization of the installation is improved by reducing the size of the equipment, and there is an advantage that the thermal efficiency is greatly improved due to the drying using the integrated heating chamber (10).
