[0020] See also Figure 1 , Figure 2 and Figure 4 A plastic product trimming device comprises a battery box 1. One end of the battery box 1 is provided with an end cover 2 for facilitating replacement of a battery installed inside the battery box 1. The other end of the battery box 1 is provided with a power chamber 4. A single-chip microcomputer 9 electrically connected to the battery box 1 is provided inside the power chamber 4. An operation panel 5 electrically connected to the single-chip microcomputer 9 is provided on the shell of the power chamber 4. The single-chip microcomputer 9 is electrically connected to a motor 10. The motor 10 outputs a rotation speed through a transmission rod 11. A conical trimming grinding head 7 is provided on the outside of the end of the transmission rod 11. A plastic softening end 8 is provided at the end of the trimming grinding head 7. A heating wire 14 is provided inside the plastic softening end 8. The heating wire 14 is electrically connected to a conductive rotating slip ring 6 provided between the power chamber 4 and the trimming grinding head 7. The conductive rotating slip ring 6 is electrically connected to the single-chip microcomputer 9 through a conductive sliding sheet 16.

[0021] See also Figure 1 and Figure 2 A non-slip sleeve 3 is arranged outside the battery box 1, and the non-slip sleeve 3 is a silicone sleeve. The battery box 1 is fixedly glued to the non-slip sleeve 3. This arrangement makes it convenient for the staff to hold the non-slip sleeve 3 to work, thereby increasing the friction between the hand and the device and preventing the studio from slipping.

[0022] See also Figure 2 The transmission rod 11 and the trimming grinding head 7 are reinforced by the reinforcing ribs 12. Such a configuration can increase the connection strength between the transmission rod 11 and the trimming grinding head 7 through the reinforcing ribs 12, thereby preventing the trimming grinding head 7 from slipping when the trimming grinding head 7 is driven to rotate.

[0023] See also Figure 2 The end of the transmission rod 11 is connected to the heat insulation board 13, and the heat insulation board 13 is arranged between the trimming grinding head 7 and the plastic softening end 8. The heat insulation board 13 and the plastic softening end 8 are sealed and connected together. Such an arrangement can reduce the dissipation of heat to the outside through the heat insulation board 13, thereby improving the heat utilization rate and quickly heating the plastic softening end 8.

[0024] See also Figure 2 and Figure 4 A rotary sealing slip ring 15 is arranged between the conductive rotating slip ring 6 and the power chamber 4. The rotary sealing slip ring 15 is fixedly connected to the conductive rotating slip ring 6. The rotary sealing slip ring 15 is rotationally sealed and connected to the power chamber 4. This arrangement allows the rotary sealing slip ring 15 to rotate along with the conductive rotating slip ring 6. During this process, the power chamber 4 does not rotate. The power chamber 4 is sealed by the rotary sealing slip ring 15 to prevent dust and sewage from entering the power chamber 4.

[0025] See also Figure 3 The trimming grinding head 7 includes a first trimming area 701 close to the plastic softening end 8, a second trimming area 702 is arranged on the other side of the first trimming area 701, and a third trimming area 703 is arranged on the other side of the second trimming area 702. The mesh numbers of the first trimming area 701, the second trimming area 702, and the third trimming area 703 increase uniformly in sequence. This arrangement facilitates the use of the first trimming area 701, the second trimming area 702, and the third trimming area 703, whose mesh numbers increase uniformly in sequence, to gradually polish and grind the plastic burrs, thereby improving the grinding effect.

[0026] Working principle: When using this device, first open the end cover 2, install the battery into the battery box 1, and then screw the end cover 2 to the end of the battery box 1. The staff holds the battery box 1 and inputs the working instruction through the operation panel 5. The operation panel 5 feeds back the working instruction to the single-chip microcomputer 9, and the single-chip microcomputer 9 starts the motor 10 according to the input working instruction. At the same time, the single-chip microcomputer 9 controls the battery box 1 to supply power to the heating wire 14 through the conductive slide 16 and the conductive rotating slip ring 6. The heating wire 14 converts electrical energy into thermal energy, and the heat is dissipated to heat the plastic softening end 8. The staff holds the device and fits the heated plastic softening end 8 to the part of the plastic product to be trimmed. The burrs of the plastic product are heated by the plastic softening end 8 to soften the burrs. After the burrs are softened, the staff trims and grinds the plastic product through the trimming grinding head 7 to make the burrs fit tightly to the edge of the plastic product to avoid the generation of plastic dust, thereby ensuring the cleanliness of the working environment and protecting the health of the staff.
