Wherein, the roll film 300 comprises a wrapping area 310, and the size of the wrapping area 310 can be adjusted by using roll films 300 with different sizes. Therefore, the roll film 300 in the present embodiment can be suitably used for packaging bearing rollers of different diameters. The film body of the wrapping area 310 extends towards the same side to form a sealing area 320, the sealing area 320 comprises an outer layer rolling film 321 and an inner layer rolling film 322, and when the heating tube 100 is close to the outer layer rolling film 321 and the inner layer rolling film 322, the outer layer rolling film 321 and the inner layer rolling film 322 are fused to form a sealing state.
Further, the body 200 is provided with a blocking unit 210, and the blocking unit 210 is used for blocking and limiting the heating tube 100 so as to prevent the heating tube 100 from overheating the roll film 300. The blocking unit 210 has a limiting baffle 211, the limiting baffle 211 is located on one side of the outer layer rolling film 321, and the free end of the limiting baffle 211 is attached to the outer layer rolling film 321 at the corresponding position, so that the outer layer rolling film 321 at the corresponding position is close to the heating tube 100.

As shown in fig. 3 and 4, the heat sealing device of the present embodiment includes a heating tube 100, and the heating tube 100 is made of a hollow tube made of a specific material. The heat generating tube 100 is provided with a mounting portion 110, a voltage applying portion 120, and a heat sealing portion 130, and the heat sealing portion 130 and the mounting portion 110 are communicated through the voltage applying portion 120. The mounting part 110 has two free ends, and the heat generating tube 100 is mounted to the packing mechanism through the free ends of the mounting part 110. An air inlet 111 is provided at a free end of the mounting portion 110, and the packaging mechanism blows hot air into the heat pipe 100 through the air inlet 111. The heat sealing portion 130 is provided with a through hole through which air introduced from the air inlet 111 passes through the voltage applying portion 120 and then escapes.
Preferably, the through holes of the heat-sealing part 130 are opened at the same interval, and by applying a specific voltage to the voltage applying part 120, the air escaping from the through holes is at a set temperature and is uniformly blown onto the roll film 300.
In order to ensure that the pressure and the flow rate of the air blown into the heating tube 100 are fixed, the heat sealing device of the embodiment includes a pressure regulating valve and a flow meter, wherein the pressure regulating valve is used for controlling the air pressure value of the air in the heating tube 100, and the value range of the air pressure value is 0.2-0.5MPa. The flow meter is used for controlling the flow of air in the heating tube 100, and the flow rate ranges from 3L/min to 5L/min.
When the film fusing device works, the heating tube 100 is driven by the driving part cylinder of the packaging mechanism to extend forwards and is close to the outer layer rolled film 321 and the inner layer rolled film 322 to be fused. When air with a certain pressure and flow is blown into the heat-generating tube 100, the through-holes of the heat-sealing portion 130 blow out hot air with a set constant temperature, and the hot air blown out from the heat-generating tube 100 fuses the two layers of the roll films together to form a sealed state. Thereby achieving the packaging effect. When the heating tube 100 is not in operation, the blowing of air into the heating tube 100 is stopped, the heating tube is driven by the air cylinder to return, and the heating tube is separated from the roll film 300 by a certain distance, so that the roll film 300 is prevented from being melted due to overheating of residual heat of the heating tube 100.
In addition, the optimal hot-melting temperature of the roll film is a fixed value, and the roll film can not be melted together or can be broken due to excessive temperature fluctuation. Because the heat sealing part 130 is provided with a plurality of through holes, a lot of heat can be taken away by blowing air into the heating tube 100, so that the temperature in the heating tube 100 is rapidly reduced, at the moment, the temperature control system can increase the temperature, and the temperature can be rapidly increased as a result, so that the temperature fluctuation range is overlarge.
In contrast, in the method of roll-film wrapping the bearing roller by using any of the wrapping mechanisms of the present embodiment, the pressure and the flow rate of the air blown into the heat-generating tube 100 are first ensured to be fixed values, and as described above, the pressure and the flow rate of the air blown into the heat-generating tube 100 can be accurately controlled by using the high-precision pressure regulating valve and the flow meter. The air pressure value is generally set to be between 0.2 and 0.5MPa, and the flow is set to be between 3L and 5L/min. Under the premise, collecting the current and voltage values of the heating tube 100 at 0-300 ℃ to form a temperature coefficient value; forming a characteristic coefficient according to the heating speed of the heating tube material; and then according to the influence of the environment temperature on the temperature of the heating tube, a temperature compensation coefficient is formed.
In the operation of the heat generating tube, different heating temperatures are set according to the thickness of the roll film 300, and the heat sealing temperature of the roll film 300 of 0.1mm is usually between 240 and 260 degrees. Through the real-time detection to the heating tube 100 temperature, including the detection of voltage and electric current, control system compares the magnitude of voltage current that detects according to the temperature value and the parameter that set for, and the voltage electric current of quick adjustment heating tube 100 to according to the characteristic and the ambient temperature of heating tube 100 material, add certain compensation coefficient, can make the temperature fluctuation scope no longer than 1 degree, effectively promote the hot melt effect to rolling up the membrane.
