Description

Technical Field

[0001] This utility model relates to the field of flame gun technology, and in particular to a pretreatment flame gun for a spraying line. Background Technology

[0002] Products such as PP plastics, packaging bottles, and hardware need to be heat-treated with a flame gun before spraying. The high temperature of the flame gun removes contaminants such as oil and burrs, enhancing the adhesion and durability of subsequent coatings. The core principle of a flame gun is to concentrate heat energy onto a specific object by spraying a controlled, high-temperature flame.

[0003] The flame gun ignites through an ignition electrode. To facilitate ignition, the ignition electrode needs to be fixed to the flame gun. In the existing technology, the ignition electrode is generally fixed to the mixer by a clamp. Since the mixer is a cylindrical structure, the clamp may rotate around the mixer under the influence of gravity. This will cause the position of the ignition electrode to shift, which will affect the normal ignition of the flame gun. Utility Model Content

In this way, the ignition electrode is fixed to the flame gun head by the fixed baffle plate, making the fixing of the ignition electrode convenient and stable.

[0006] Furthermore, the fixing plate is an L-shaped structural component, with one side of the fixing plate fixed to the flame gun head and the other side fixed to the ignition electrode.

[0007] Furthermore, the flame gun head includes a main body and a head, with the head fixed to the main body and the fixing plate fixed to the head.

[0008] Furthermore, the nozzle head has multiple rows of flame holes.

[0010] Furthermore, the flame gun head also includes a stainless steel sintered mesh plate, which is disposed in the groove.

[0011] Furthermore, the ignition head of the ignition electrode is aligned with the groove.

[0012] Furthermore, regulating valves are provided between the first intake pipe and the first connector, and between the second intake pipe and the second connector.

[0013] The beneficial effects of this utility model are: This utility model is equipped with a fixed folding plate, which has an L-shaped structure and the contact surfaces with the flame gun head and the ignition electrode are both flat. The flat contact surfaces can improve the stability of the ignition electrode connection.

[0014] The stainless steel sintered mesh plate of this utility model is located in the groove, which has the function of stabilizing the flame, optimizing the combustion efficiency, dispersing heat, and preventing the flame gun head from cracking under high temperature.

[0021] like Figure 1-4As shown, a pretreatment flame gun for a spraying line includes a mixer 1, a first air inlet pipe 2, a second air inlet pipe 3, and a flame gun head 4. Specifically, the mixer 1 is equipped with three connectors: a first connector 101, a second connector 102, and a third connector 103. The first connector 101 and the second connector 102 are located at the same end and have a forked design, which allows for more operating space and easier layout. The first air inlet pipe 2 is connected to the first connector 101 and is used to supply combustible gas (such as acetylene or propane) to the mixer 1. The second air inlet pipe 3 is connected to the second connector 102 and is used to supply combustion-supporting gas (oxygen). By pre-mixing the combustion-supporting gas and the combustible gas through the mixer 1, a high-temperature flame can be generated. The flame gun head 4 is connected to the third connector 103. The mixture is supplied to the flame gun head 4 and finally ignited at the flame gun head 4, thereby generating a high-temperature flame to remove oil, burrs, and other contaminants from the product.

[0022] In this embodiment, the flame gun head 4 has a flat structure, which can generate a flat flame. The flat flame is shaped like a flame brush and can cover a wide rectangular area instead of a concentrated point. It transforms heat from a point into a line, thereby achieving uniform, efficient, and directional large-area heating.

[0023] A pretreatment flame gun for a spraying line also includes a fixing baffle plate 5 and an ignition electrode 6. Specifically, the fixing baffle plate 5 is fixed to the flame gun head 4 by a connecting component, and the ignition electrode 6 is fixed to the fixing baffle plate 5 by a connecting component. In this way, the ignition electrode 6 is fixed to the flame gun head 4 by the fixing baffle plate 5, making the fixing of the ignition electrode 6 convenient and stable. The fixing baffle plate 5 is an L-shaped structural component, and both sides of the fixing baffle plate 5 are flat. One side of the fixing baffle plate 5 is fixed to the flame gun head 4, and the other side is fixed to the ignition electrode 6. The flat contact surface can improve the stability of the connection of the ignition electrode 6.

[0024] In this embodiment, the connecting components are bolts and nuts, and there are multiple bolts and nuts. That is, the fixing plate 5 is fixed to the bottom of the flame gun head 4 by bolts and nuts, and the ignition electrode 6 is fixed to the fixing plate 5 by bolts and nuts.

[0025] In this embodiment, the flame gun head 4 includes a main body 401 and a head 402. The head 402 is fixed to the main body 401, and the fixing plate 5 is fixed to the head 402. The main body 401 has multiple rows of flame holes 4021, which can increase the working area of ​​the flame gun head 4.

[0026] In this embodiment, the number of rows of flame holes 4021 is four, and the flame holes 4021 in the same row are arranged at equal intervals.

[0027] In this embodiment, the front end face of the nozzle head 402 has two grooves 4022, which are located on the upper and lower sides of the front end face of the nozzle head 402, respectively. The flame nozzles 4021 in the uppermost and lowermost rows are located in the grooves 4022. The ignition head of the ignition electrode 6 is aligned with the lower groove 4022 to ignite the flame gun.

[0028] In this embodiment, the flame gun head 4 also includes two stainless steel sintered mesh plates 403. The two stainless steel sintered mesh plates 403 have a V-shaped structure and are respectively disposed in two grooves 4022. The stainless steel sintered mesh plates 403 are fixed in the grooves 4022 by friction. That is, the stainless steel sintered mesh plates 403 are directly inserted into the grooves 4022, which has the function of stabilizing the flame, optimizing the combustion efficiency, dispersing heat, and preventing the flame gun head 4 from cracking under high temperature conditions.

[0029] In this embodiment, regulating valves 7 are provided between the first air inlet pipe 2 and the first connector 101, and between the second air inlet pipe 3 and the second connector 102. By controlling the flow rate of the two air inlets with two independent regulating valves 7, the operator can precisely adjust the ratio of oxygen and combustible gas to create different types of flames to meet the needs of different tasks.
