Description

Technical Field

[0001] This utility model relates to the field of label production technology, and in particular to a device for testing the high temperature resistance of self-adhesive labels. Background Technology

[0002] With the development of industrial technology, self-adhesive labels are widely used in high-temperature environments in fields such as electronics, automobiles, pharmaceuticals, and steel. However, many self-adhesive labels are prone to problems such as edge curling, detachment, and adhesive failure under prolonged high temperatures, which seriously affects their reliability. Therefore, high-temperature resistance tests are required after processing.

[0003] In the prior art, traditional self-adhesive labels require high-temperature heating during high-temperature resistance testing. However, because self-adhesive labels melt in high-temperature environments, they produce harmful high-temperature gases. Traditional high-temperature resistance testing devices lack the ability to adsorb these gases during the testing process, leading to gas emissions that severely pollute the working environment and endanger the health of workers. Therefore, this utility model proposes a high-temperature resistance performance testing device for self-adhesive labels to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature resistance testing device for self-adhesive labels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-temperature resistance testing device for self-adhesive labels includes a testing chamber and a cooling chamber. The cooling chamber contains cold water. An adsorption mechanism for adsorbing gas within the testing chamber is located on the rear wall of the testing chamber. The adsorption mechanism includes an air intake shell fixedly connected to the rear wall of the testing chamber and communicating with the testing chamber. An air inlet pipe is fixedly connected to the upper end of the air intake shell and communicating with it. An exhaust fan is rotatably connected to the inner wall of the air intake shell. A heat exchange coil is fixedly connected through the inner wall of the cooling chamber. One end of the air inlet pipe is connected to the heat exchange coil. A purifier is installed on the side wall of the cooling chamber away from the testing chamber and communicating with the other end of the heat exchange coil. An exhaust pipe is fixedly connected to the end of the purifier away from the heat exchange coil and communicating with it. A stirring mechanism for agitating the cold water within the cooling chamber is also provided.

[0007] Preferably, a test platform is provided at the bottom of the test chamber, and electric heating plates are installed on the inner walls at both ends of the test chamber.

[0008] Preferably, the stirring mechanism includes a rotating rod that is rotatably connected to the side wall of the cooling tank through a sealed passage, and a plurality of stirring blades that are equally spaced are fixedly sleeved on the rotating rod.

[0009] Preferably, a motor is fixedly connected to the outer wall of the air intake shell, the end of the output shaft of the motor is fixedly connected to the shaft of the exhaust fan, and synchronous pulleys are fixedly sleeved on both the output shaft of the motor and the rotating rod, and the two synchronous pulleys are connected by a synchronous belt drive.

[0010] Preferably, the front end of the test box is provided with an opening, a door is provided at the opening, and an observation window is provided on the door.

[0011] Preferably, the side wall of the cooling tank is provided with a hot water outlet pipe and a cold water inlet pipe.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up an adsorption mechanism, a cooling box, and a purifier, during testing, the output shaft of the drive motor rotates, driving the exhaust fan to rotate. The rotation of the exhaust fan creates a negative pressure inside the suction chamber, drawing the gas out of the test chamber and into the heat exchange coil through the inlet pipe. The heat exchange coil passes through the cooling box, where cold water immerses the heat exchange coil, cooling the high-temperature gas inside. Simultaneously, the cooled exhaust gas enters the purifier for purification, effectively treating the exhaust gas and avoiding the health threats posed by harmful gas pollution and heat pollution to workers.

[0014] 2. By setting up a stirring mechanism, during the rotation of the motor output shaft, the rotating rod rotates under the transmission of the synchronous pulley and synchronous belt. The rotation of the rotating rod can drive the stirring blades to rotate, and the rotation of the stirring blades can agitate the water in the cooling tank, so that it comes into uniform contact with the surface of the heat exchange coil, thereby achieving a better heat exchange effect, improving the cooling effect on high-temperature gas, and improving the practicality of the device.

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0024] Reference Figure 1-7 A high-temperature resistance testing device for self-adhesive labels includes a test chamber 1 and a cooling chamber 4. The cooling chamber 4 is filled with cold water. A test platform 14 is installed at the bottom of the test chamber 1. Electric heating plates 15 are installed on the inner walls at both ends of the test chamber 1.

The door 2 and the test chamber 1 are hinged together, and the observation window 3 is made of transparent high-temperature resistant glass. A hot water outlet pipe 12 and a cold water inlet pipe 13 are provided on the side wall of the cooling chamber 4. When the temperature of the cold water in the cooling chamber 4 is too high, it can be discharged through the hot water outlet pipe 12, and new cold water can be introduced through the cold water inlet pipe 13.

[0025] Specifically, the rear wall of the test chamber 1 is provided with an adsorption mechanism for adsorbing the gas inside the test chamber 1. The adsorption mechanism includes an air intake shell 11 fixedly connected to the rear wall of the test chamber 1. The air intake shell 11 is connected to the test chamber 1. An air inlet pipe 9 is fixedly connected to the upper end of the air intake shell 11 and is connected to it. An exhaust fan 19 is rotatably connected to the inner wall of the air intake shell 11. A heat exchange coil 18 is fixedly connected through the inner wall of the cooling chamber 4. The air inlet pipe 9 is connected to one end of the heat exchange coil 18. A purifier 5 is installed on the side wall of the cooling chamber 4 away from the test chamber 1. The purifier 5 is connected to the other end of the heat exchange coil 18. An exhaust pipe 6 is fixedly connected to the end of the purifier 5 away from the heat exchange coil 18 and is connected to it.

[0026] Specifically, the cooling tank 4 is equipped with a stirring mechanism for stirring the cold water inside the cooling tank 4. The stirring mechanism includes a rotating rod 17 that is rotatably connected to the side wall of the cooling tank 4 through a sealed passage. Multiple sets of equally spaced stirring blades 16 are fixedly sleeved on the rotating rod 17. A sealing ring is provided at the position where the rotating rod 17 passes through the side wall of the cooling tank 4 to achieve a sealing effect and prevent water from seeping out.

[0027] Specifically, a motor 10 is fixedly connected to the outer wall of the air intake shell 11. The end of the output shaft of the motor 10 is fixedly connected to the shaft of the exhaust fan 19.

[0028] In use, the door 2 is opened, the label is affixed to the upper part of the test bench 14, and then the electric heating plate 15 is activated to generate high temperature for product testing. During the test, the output shaft of the drive motor 10 rotates, driving the exhaust fan 19 to rotate. The rotation of the exhaust fan 19 creates a negative pressure inside the suction shell 11, drawing the gas out of the test chamber 1 and into the heat exchange coil 18 through the air inlet pipe 9. The heat exchange coil 18 then passes through the cooling box 4, where cold water submerges the heat exchange coil 18, thus cooling the high-temperature gas inside the heat exchange coil 18. Meanwhile, the cooled exhaust gas enters the purifier 5 for purification, thus treating the exhaust gas and effectively avoiding the health threats to workers caused by harmful gas pollution and heat pollution. During the rotation of the output shaft of the motor 10, the rotating rod 17 rotates under the transmission of the synchronous pulley 7 and the synchronous belt 8. The rotation of the rotating rod 17 can drive the stirring blade 16 to rotate. The rotation of the stirring blade 16 can agitate the water in the cooling box 4, so that it is in uniform contact with the surface of the heat exchange coil 18, thereby achieving a better heat exchange effect and improving the cooling effect of high temperature gas.
