DETAILED DESCRIPTION

[0022] The technical solution in the embodiment of the present application is to solve the problems mentioned in the above background technology, and the overall idea is as follows:

[0023] See also Figure 1-4 A cooling device includes an inner tube 10, the air nozzle of the inner tube 10 is connected to an air pipe 20, the air pipe 20 is connected to an air blowing mechanism 30, and also includes a reversing mechanism 40 and a blowing and sucking mechanism 50, the air pipe 20 is respectively connected to the blowing and sucking mechanism 50 and the air blowing mechanism 30 through the reversing mechanism 40, a heat exchange mechanism 60 is arranged between the reversing mechanism 40 and the blowing and sucking mechanism 50, and the heat exchange mechanism 60 is connected to an external cooling water device. Among them, the reversing mechanism 40 is used to switch the flow direction of the air pipe 20 to the blowing and sucking mechanism 50, so as to adapt to the original vulcanization equipment, and the blowing and sucking mechanism 50 is used to suck out and blow back the hot air circulation inside the inner tube 10, so that the hot air circulation passes through the heat exchange mechanism 60 to achieve the effect of heat dissipation, improve the cooling effect, have little effect on the temperature of the mold 80, and transfer the heat through the cooling water, reduce the temperature in the workshop, and improve the comfort of personnel.

[0024] See also Figure 1-4 The reversing mechanism 40 is an electromagnetic reversing valve. Here, the electromagnetic reversing valve connects the inner tube 10 with the inflation mechanism 30 before vulcanization begins, and connects the blowing and sucking mechanism 50 with the inner tube 10 after vulcanization. It should be noted that the inflation mechanism 30 is a mechanism of the vulcanizer 70, that is, by injecting high-pressure steam into the inner tube 10, the inner tube 10 is helped to expand and vulcanize.

[0025] See also Figure 1-4 The heat exchange mechanism 60 includes a water pan 61, a heat sink 62 is fixedly connected to the water pan 61, and a cooling water flow channel 63 is built into the water pan 61. Here, the heat sink 62 absorbs the heat in the inner tube 10 and transfers the heat to the water pan 61. The external cooling water circulation device circulates the cold water into the water pan 61 to take away the heat.

[0026] See also Figure 1-4 The heat exchange mechanism 60 further includes a baffle plate 64, which is fixedly connected to the water pan 61. The heat sink 62 is arranged between the baffle plate 64 and the water pan 61. The center of the water pan 61 is provided with an air duct connected to the reversing mechanism 40. Here, the baffle plate 64 is used to guide the airflow to fully blow over the surface of the heat sink 62 and then enter the blowing and suction mechanism 50 at the rear, which is conducive to improving the heat exchange efficiency of the heat sink 62.

[0027] See also Figure 1-4 The blowing and sucking mechanism 50 includes a cylinder 51 and a piston 52. The water tray 61 is fixedly blocked at one end of the cylinder 51, and the piston 52 is slidably connected in the cylinder 51. Here, the piston 52 reciprocates in the cylinder 51, thereby extracting and blowing air in the inner tube 10, continuously taking heat out of the inner tube 10, and the heat outside the inner tube 10 contacts the outside air for natural heat dissipation.

[0028] See also Figure 1-4 The blowing and sucking mechanism 50 also includes a motor 53 and a connecting rod 54. The upper shaft of the output end of the motor 53 is connected to an eccentric wheel 55, and the connecting rod 54 is hinged between the piston 52 and the eccentric wheel 55. Here, the motor 53 drives the eccentric wheel 55 to rotate, and pushes the piston 52 to reciprocate through the connecting rod 54. In this embodiment, the volume of the cylinder 51 is the same as the volume of the inner tube 10. Each time the piston 52 goes back and forth, the air in the inner tube 10 circulates once. If it is necessary to adapt to inner tubes 10 of different specifications, the eccentric wheel 55 needs to be replaced to change the stroke of the piston 52.

[0029] See also Figure 1-4 The utility model further provides a high elastic butyl inner tube processing equipment, including the above-mentioned cooling device and a vulcanizer 70, the vulcanizer 70 is provided with a mold 80, the inner tube 10 is arranged in the mold 80, and the air pipe 20 is arranged on the vulcanizer 70. Here, the inner tube 10 is placed in the mold 80, and is connected with the air blowing mechanism 30 through the air pipe 20. The air blowing mechanism 30 is used to blow steam for the inner tube 10 to meet the needs of high temperature vulcanization, and the air pipe 20 is also used to blow and absorb heat. Therefore, it can be quickly cooled just after the vulcanization is completed, without the need for workers to operate, thereby improving work efficiency.

[0030] See also Figure 1-4 , the reversing mechanism 40 and the blowing and sucking mechanism 50 are both arranged in the vulcanizing machine 70. Here, the ventilation mechanism and the blowing and sucking mechanism 50 are integrated in the vulcanizing machine 70 to reduce the floor space.

[0031] When the present application is used: the air nozzle of the inner tube 10 is connected to the air pipe 20, the vulcanizer 70 starts working to press the inner tube 10 between the upper and lower molds 80, and the external inflation mechanism 30 injects high-pressure steam into the inner tube 10 to inflate the inner tube 10 tightly against the inner wall of the mold 80. After the vulcanization is completed, the electromagnetic reversing valve guides the air pipe 20 to the center of the water tray 61, and the motor 53 drives the eccentric wheel 55 to rotate, and pushes the piston 52 to reciprocate through the connecting rod 54, so that the air in the inner tube 10 is sucked out and blown back, and the air is continuously circulated. When circulating, the airflow passes through the heat sink 62, transfers the heat to the water tray 61, and is then sucked away by the cooling water in the water tray 61, thereby achieving the effect of rapid heat dissipation, without the need for manual operation, improving work efficiency, and not dissipating heat to the operating area, thereby avoiding the problem of high temperature in the high-temperature vulcanization workshop and improving the comfort of the operator.

[0032] In summary, the reversing mechanism 40 is used to switch the flow direction of the air pipe 20 to the blowing and sucking mechanism 50, so as to adapt to the original vulcanization equipment. The blowing and sucking mechanism 50 is used to suck out and blow back the hot air circulation inside the inner tube 10, so that the hot air circulates through the heat exchange mechanism 60 to achieve the effect of heat dissipation, thereby improving the cooling effect, having little impact on the temperature of the mold 80, and transferring the heat through cooling water, thereby reducing the temperature in the workshop and improving the comfort of personnel.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
