[0026] See also Figure 1-5 The utility model provides a technical solution of a cutting device for processing ABS plastic surface coating: a cutting device for processing ABS plastic surface coating, comprising a cutting head 1 and used for cutting the ABS plastic surface coating, the cutting head 1 comprising:

[0027] The main body component 11 comprises a connector 112 fixed at the lower end of the housing 111, a nozzle 113 inserted and installed inside the lower end of the connector 112, and a ring frame 118 integrally formed on the outer wall of the nozzle 113;

[0028] The mounting assembly 12 includes a clamping head 121 hinged on both sides of the lower end of the connector 112, a sliding sleeve 122 slidably mounted on the lower end of the connector 112, and a spring 123 mounted on the outer wall of the connector 112;

[0029] The protection assembly 13 includes two installation shells 131 symmetrically installed on the outer wall of the connector 112 and a protection shell 132 integrally formed on the outer wall of the installation shells 131 .

[0030] In this embodiment, when the nozzle 113 needs to be replaced, the squeeze on the clamping head 121 is released by pushing the sliding sleeve 122 upward, so that the clamping head 121 can be pushed to flip over, and the clamping head 121 is released from fixing the nozzle 113, so that the nozzle 113 can be removed, and then the nozzle 113 is inserted and installed to the connecting head 112, and the pushed clamping head 121 is released, and then the pushed sliding sleeve 122 is released, and the rebound pressure of the spring 123 pushes the sliding sleeve 122 to squeeze the clamping head 121, so that the clamping head 121 buckles the nozzle 113 and fixes it on the connecting head 112, thereby realizing convenient replacement of the nozzle 113.

[0031] Specifically, the protection component 13 also includes grooves 133 opened on both sides of the protection shell 132, a pipeline 135 arranged above the protection shell 132, nozzles 136 installed at both ends of the pipeline 135, and an inert gas pipe 137 connected to the upper end of the pipeline 135.

[0032] In this embodiment, when the protective component 13 is installed on the connecting head 112, the cutting head 1 is cutting the ABS plastic surface coating, and the flame ejected from the nozzle 113 is relatively strong and close to the ABS plastic surface coating, the flame will return upward. At this time, the protective shell 132 can be used to block it to prevent the flame from getting out of control and burning the main component 11 or other equipment; at the same time, the inert gas is sent to the pipeline 135 through the inert gas pipe 137 and ejected from the nozzle 136, so as to further reduce the spread of the flame returning upward and prevent the returning flame from damaging the ABS plastic coating at the cutting point.

[0033] Specifically, the protection assembly 13 further includes mounting heads 134 fixed to both ends of the mounting shell 131 , and the two mounting shells 131 and the protection shell 132 are fixed to the connecting head 112 through the mounting heads 134 and bolts.

[0034] In this embodiment, the two installation shells 131 and the protective shell 132 can be disassembled from the connector 112 , so that the protective assembly 13 can be cleaned or replaced easily.

[0035] Specifically, the mounting assembly 12 further includes a limiting ring 125 fixed to the outer wall of the middle portion of the connector 112 , and a limiting seat 126 fixed to the bottom of the connector 112 .

[0036] In this embodiment, the spring 123 is limited by the limiting ring 125 , and the sliding sleeve 122 is limited by the limiting seat 126 , so as to prevent the sliding sleeve 122 from being separated from the connector 112 .

[0037] Specifically, the installation assembly 12 further includes a sealing gasket 124 installed inside the connector 112 , and the sealing gasket 124 cooperates with the nozzle 113 .

[0038] In this embodiment, when the nozzle 113 is installed on the connector 112, the sealing gasket 124 is used to improve the sealing performance to prevent gas leakage.

[0039] Specifically, the main body assembly 11 further includes a fuel pipe 114 and an oxygen pipe 115 installed on both sides of the upper end of the shell 111 , and a fuel valve 116 and an oxygen valve 117 installed in the shell 111 .

[0040] The working principle and use process of the utility model are as follows: first, when the nozzle 113 needs to be replaced, the sliding sleeve 122 is pushed upward to release the squeezing of the clamping head 121, so that the clamping head 121 can be pushed to flip in the opposite direction, and the clamping head 121 is released from fixing the nozzle 113, so that the nozzle 113 can be removed, and then the nozzle 113 is inserted and installed to the connecting head 112, and the pushed clamping head 121 is released, and then the pushed sliding sleeve 122 is released, and the sliding sleeve 122 is pushed to squeeze the clamping head 121 by the rebound pressure of the spring 123, so that the clamping head 121 buckles the nozzle 113 and fixes it on the connecting head 112, so that the nozzle 113 can be easily replaced;

[0041] When the cutting head 1 is cutting the ABS plastic surface coating, and the flame ejected from the nozzle 113 is relatively strong and close to the ABS plastic surface coating, the flame may return upwards. At this time, the protective shell 132 may be used to shield it, so as to prevent the flame from getting out of control and burning the main component 11 or other equipment. At the same time, the inert gas is sent to the pipeline 135 through the inert gas pipe 137 and ejected from the nozzle 136, so as to further reduce the spread of the flame returning upwards and prevent the returning flame from damaging the ABS plastic coating at the cutting point.
