[0037] As Figures 1 to 6 shown, the automatic feeding wire harness heat shrinkage device of the present utility model includes a heat shrinkage mechanism 100, a winding mechanism 200, and a control mechanism 300. The heat shrinkage mechanism 100 generates high temperature to cause the heat shrinkable tube outside the wire harness 500 to shrink thermally; the winding mechanism 200 is used to wind the wire harness 500; the control mechanism 300 is used to control the operation of the heat shrinkage mechanism 100 and the winding mechanism 200.

[0038] Please refer to Figure 1 , Figure 4 and Figure 6 shown, the heat shrinkage mechanism 100 includes a heating element 110. The heating element 110 is provided with a wire passing hole 111. The wire passing hole 111 is horizontally arranged transversely and penetrates through both ends. The wire passing hole 111 includes a feeding end 112, a heating section 114, and a discharging end 115 arranged in sequence. In practical applications, the wire harness 500 sleeved with the heat shrinkable tube enters the heating element 110 from the feeding end 112; the heating section 114 can generate high temperature. When the wire harness 500 passes through the heating section 114, the heat shrinkable tube outside the wire harness 500 shrinks thermally; the wire harness 500 after thermal shrinkage is discharged through the discharging end 115.

[0039] Specifically, a heating component 117 is provided inside the heating element 110. The heating component 117 generates heat, and the heat is conducted to the heating section 114 to achieve thermal shrinkage. The heating component 117 is arranged around the heating section 114 to ensure uniform heat conduction. A plurality of uniformly distributed air holes are provided on the inner wall of the heating section 114. The air holes connect the wire passing hole 111 with the heating component 117. The provision of the air holes can improve the heat conduction efficiency and reduce heat loss. Further, a temperature sensor is provided inside the heating element 110. The temperature sensor is used to sense the temperature of the heating component 117 and transmit the detection data to the control mechanism 300.

[0040] In this embodiment, the heating component 117 is a plurality of heating wires 118 arranged evenly. A housing 120 is provided at the rear side of the heating element 110.

At the same time, an adjustable resistor 140 is provided between the power supply 130 and the heating wires 118; the control mechanism 300 is connected to the adjustable resistor 140, and the control mechanism 300 adjusts the temperature of the heating wires 118 by adjusting the resistance of the adjustable resistor 140.

[0041] Specifically, the wire passing hole 111 further includes a cooling section 116. The cooling section 116 is provided between the heating section 114 and the discharging end 115. As Figure 6 shown, the wire harness section A completes heat shrinkage and enters the cooling section 116 for natural cooling.

[0042] Specifically, the cross-sectional shape of the wire passing hole 111 is rectangular. The feeding end 112 is provided with a positioning hole. The positioning hole is provided at the intersection of the diagonal lines of the cross-section of the wire passing hole 111. The wire harness 500 enters the heating section 114 through the positioning hole. Due to the limiting effect of the positioning hole, the wire harness 500 is located at the central part of the heating section 114 and can receive heat from all directions, being heated evenly and improving the heat shrinkage quality.

[0043] Please refer to Figure 1 、 Figure 2 and Figure 5 shown, the winding mechanism 200 includes a driving element 210, a driving shaft 220 drivingly connected to the driving element 210, and a turntable 230 fixedly connected to the driving shaft 220; one end of the wire harness 500 is fixed to the outside of the turntable 230, and the driving element 210 drives the turntable 230 to rotate to realize the winding of the wire harness 500.

[0044] Specifically, in this embodiment, the driving element 210 adopts a motor. The control mechanism 300 is electrically connected to the motor. The control mechanism 300 can control the start and stop and the rotation speed of the motor, and further control the winding speed and the duration of the heat shrinkage of the wire harness 500.

[0045] Specifically, the turntable 230 includes a rotating part 231 fixedly connected to the drive shaft 220, and a baffle 232 assembled and connected to the rotating part 231; the baffle 232 is detachably connected to the rotating part 231, and an assembly groove 233 is formed between the outer wall of the baffle 232 and the rotating part 231. During actual use, the baffle 232 is removed, the winding bracket 400 is installed in the assembly groove 233, and finally the baffle 232 is installed to clamp the winding bracket 400; at the same time, bumps are provided on the outer wall of the assembly groove 233 for mating with the hole positions of the winding bracket 400, so that the winding bracket 400 rotates synchronously with the turntable 230. One end of the wire harness 500 is fixed to the winding bracket 400, and the winding bracket 400 rotates with the turntable 230 to realize the winding of the wire harness 500.

[0046] Please refer to Figures 2 - 4 As shown, the control mechanism 300 includes a controller 310 and a control panel 320 provided at the front end of the controller 310. A power switch 321, a display 322 for displaying the working conditions of the heat shrinkage mechanism 100 and the winding mechanism 200, and adjustment buttons 323 are provided on the control panel 320.

Repeat this cycle to complete heat shrinkage and natural cooling.
