Abstract
Description
Technical Field
[0001] This utility model relates to the field of glue gun welding technology, specifically to a heat insulation structure for an electromagnetic valve. Background Technology
[0002] On the glue coating production line, glue is fed into the glue gun, and compressed air is used to extrude the glue to achieve coating. For some glue guns, the glue needs to be heated to keep it in a liquid state, and the temperature may be as high as 60-80℃. Therefore, the glue gun will emit heat. The intake control of compressed air is achieved by solenoid valve. The distance between the solenoid valve and the glue gun is only a few centimeters. The air can be easily conducted to the solenoid valve through the metal intake pipe. The internal components of the solenoid valve are prone to deformation and damage after being heated, so frequent shutdowns are required for replacement, which is costly. Summary of the Invention
[0003] To address the aforementioned technical problems, this utility model provides a heat insulation structure for a solenoid valve, which can effectively improve the service life of the solenoid valve, eliminate the need for frequent replacements, reduce operating costs, and improve production efficiency.
[0004] The technical solution is as follows: a solenoid valve heat insulation structure, which includes a solenoid valve and a glue gun, characterized in that the air outlet of the solenoid valve is connected to the upper end of a high-temperature resistant insulating plate, the air inlet pipe of the glue gun is connected to the lower end of the high-temperature resistant insulating plate, and a channel is opened in the high-temperature resistant insulating plate to connect the air outlet of the solenoid valve and the air inlet pipe of the glue gun.
[0005] A further feature is that the top of the high-temperature resistant insulating board is provided with a plug for inserting into the air outlet of the solenoid valve, and the bottom is provided with a threaded hole that mates with the air inlet pipe of the glue gun. The outer surface of the plug is provided with external threads.
[0006] By adopting this utility model, a high-temperature resistant insulating plate is added between the glue gun and the solenoid valve. The air inlet pipe of the glue gun is no longer directly connected to the air outlet of the solenoid valve, but is connected by the high-temperature resistant insulating plate. The heat at the glue gun cannot be conducted to the solenoid valve, thus providing good protection for the solenoid valve. It can be used for a long time without damage, without frequent replacement, reducing the cost of use, and improving production efficiency without stopping the machine. Attached Figure Description
[0007] Figure 1 This is a schematic diagram of the structure of this utility model;
[0008] Figure 2 This is a schematic diagram of a high-temperature resistant insulation board. Detailed Implementation
[0009] See Figure 1 , Figure 2As shown, a heat insulation structure for an electromagnetic valve includes an electromagnetic valve 1 and a glue gun 2. The air outlet of the electromagnetic valve 1 is connected to the upper end of a high-temperature resistant insulating plate, and the air inlet pipe of the glue gun 2 is connected to the lower end of a high-temperature resistant insulating plate 3. The high-temperature resistant insulating plate 3 has a channel 6 that connects the air outlet 4 of the electromagnetic valve 1 and the air inlet pipe 5 of the glue gun 2. The top of the high-temperature resistant insulating plate 3 is provided with a plug 3-1 for inserting into the air outlet of the electromagnetic valve 1, and the bottom is provided with a threaded hole 3-2 that mates with the air inlet pipe 5 of the glue gun 2. The outer surface of the plug 3-1 is provided with external threads, and the connection is made through threads at both the top and bottom, making it simple and convenient to use.
[0010] After compressed air enters the solenoid valve 1, it passes through the high-temperature resistant insulating plate 3 and the air inlet pipe 5 and then enters the glue gun 2. The heat generated by the glue gun 2 is conducted upward through the air inlet pipe 5 and then blocked by the high-temperature resistant insulating plate 3, thus effectively protecting the solenoid valve 1.
