[0014] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0015] See also Figures 1 to 4 , provided in one embodiment of the present invention, is a plastic floor cutting head and cutting device, comprising a housing 101, and further comprising:

[0016] Negative pressure component 2, used to clean up the debris generated by cutting the plastic floor;

[0017] The negative pressure component 2 includes a fan blade 201, a fan blade shaft 202 and a partition 203. The two partitions 203 are fixedly connected to the shell 101 on both sides of the shell 101. The two partitions 203 are rotatably connected to the fan blade shaft 202 at the axis, and the two fan blade shafts 202 are respectively fixedly connected to the fan blades 201.

[0018] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific fan blades 201 described in the above embodiments. For example, a partition net may be provided under the fan blades 201, and the partition net is fixedly connected to the shell 101. The purpose of this setting is to facilitate the placement of longer plastic tapes in this way so that they are attracted into the device and thus wrapped around the fan blades 201, causing the fan blades 201 to be unable to rotate normally; and the fan blades can be installed at a certain angle.

[0019] Specifically, the two fan shafts 202 are fixedly connected with worm wheels 204 , and one side of the two worm wheels 204 is meshedly connected with a worm 205 .

[0020] For the above examples, those skilled in the art should know that when implementing the above technical solutions, they are not limited to the specific worm wheel 204 and worm 205 described in the above embodiments. For example, the worm wheel 204 and worm 205 can be replaced with a bevel gear assembly. The purpose of this setting is to facilitate the adjustment of the transmission ratio in this way.

[0021] Specifically, the two worms 205 are fixedly connected to the main shaft 206 , and the main shaft 206 is rotatably connected to the housing 101 .

[0022] For the above examples, those skilled in the art should be aware that when implementing the above technical solutions, they are not limited to the specific main shaft 206 described in the above embodiments. For example, bearing assemblies should be provided at both ends of the main shaft 206. The purpose of this setting is to prevent the main shaft 206 from breaking during long-term use.

[0023] Specifically, the main shaft 206 is rotatably connected to the baffle 207, and the baffle 207 is fixedly connected to the partition 203. The purpose of this arrangement is to facilitate the protection of the worm 205 and the worm wheel 204 in this way to prevent them from being damaged by debris.

For example, a sealing strip is provided at the connection between the cover plate 304 and the silo 303. The purpose of this setting is to prevent debris from overflowing through the gaps at the connection, causing secondary pollution.

[0031] In the embodiment of the present invention, when it is necessary to cut the floor, the relevant technicians place the device on the floor and start the motor 301 at the same time, so that the motor 301 drives the gear 209 meshing with its output gear to start rotating, so that the gear 209 drives the main shaft 206 fixedly connected to it to rotate synchronously, and the main shaft 206 drives the cutter disc 208 fixedly connected to it to rotate synchronously. At this time, the relevant grip push rod 305 simultaneously pushes the device at a uniform speed, so that the floor board is cut by the cutter disc 208, and at the same time the main shaft 206 drives the worm 205 fixedly connected thereto to rotate synchronously, so that the worm 205 drives the worm wheel 204 meshing with it to start rotating, so that the worm wheel 204 drives the fan shaft 202 fixedly connected thereto to start rotating, so that the fan shaft 202 drives the fan blade 201 fixedly connected to its bottom to start rotating, so that the rotation of the fan blade 201 generates negative pressure to attract the debris generated by cutting the floor, and at the same time, the debris is introduced into the hopper 303 through the curved pipe 302 to prevent excessive debris generated by cutting from being inconvenient to clean.
