DETAILED DESCRIPTION

[0019] The present invention will now be further described with reference to the accompanying drawings.

[0020] See also Figure 1 The present invention is an automatic cleaning mechanism for a mixing hose gun head, which is characterized in that it includes a rotating mechanism, a non-woven fabric driving base, a non-woven fabric, a pressure roller, and a tensioning roller. Two non-woven fabric driving bases 2 are installed on the top of the rotating mechanism. A pressure roller 1 4 and a pressure roller 2 5 that can move laterally are provided between the two non-woven fabric driving bases 2. A tensioning roller 6 that can move longitudinally is provided between the pressure roller 1 4 and the pressure roller 2 5. The two ends of the non-woven fabric 3 are respectively wound on the two non-woven fabric driving bases 2. The non-woven fabric 3 located between the two non-woven fabric driving bases 2 contacts the surfaces of the pressure roller 1 4, the tensioning roller 6, and the pressure roller 2 5 in turn. The gun head 71 of the mixing hose 7 is inserted between the pressure roller 1 4 and the pressure roller 2 5 and contacts the non-woven fabric 3.

[0021] The rotating mechanism includes a rotating base 11, a fixed base 12, a rotating support 13, and a rotating motor 14. The rotating motor 14 is installed on the fixed base 12. The shaft of the rotating motor 14 is connected to the rotating base 11 by the rotating support 13. Two non-woven fabric driving bases 2 are installed on the top of the rotating base 11.

[0022] Pressure roller 1 4 and pressure roller 2 5 are installed on the horizontal guide rail 8. Pressure roller 1 4 and pressure roller 2 5 are driven by electric cylinders or pneumatic cylinders. A spring 1 is built into the horizontal guide rail 8. One end of the spring 1 is against pressure roller 1 4 or pressure roller 2 5, and the other end of the spring 1 is connected to the adjusting knob 1. By adjusting the adjusting knob 1, the compression amount of the spring 1 can be adjusted, thereby changing the pressure provided by pressure roller 1 4 or pressure roller 2 5.

[0023] The tensioning roller 6 is installed on the vertical guide rail 9, and the vertical guide rail 9 has a built-in spring 2. One end of the spring 2 is against the tensioning roller 6, and the other end of the spring 2 is connected to the adjusting knob 2. By adjusting the adjusting knob 2, the compression amount of the spring 2 can be adjusted, thereby changing the pressure provided by the tensioning roller 6.

[0024] A displacement sensor for measuring the displacement of the tensioning roller 6 is also installed in the vertical guide rail 9, and the displacement sensor feeds back the displacement signal to the control system.

[0025] The non-woven fabric driving base 2 includes a base body and a driving motor 21. The driving motor 21 is installed on the base body. The shaft of the driving motor 21 is connected to the central axis of the non-woven fabric 3. The driving motor 21 can drive the non-woven fabric roll to rotate, thereby moving the non-woven fabric 3 between the two non-woven fabric driving bases 2.

[0026] The driving motor 21 is a speed-adjustable motor so as to adjust the moving speed of the nonwoven fabric 3 .

[0027] The two ends of the non-woven fabric 3 are wound separately and formed on the non-woven fabric drive base 2 to form a clean non-woven fabric roll and a discarded non-woven fabric roll, facilitating the supply of clean non-woven fabric and the recycling of discarded non-woven fabric that has accumulated glue. When using the non-woven fabric for the first time or replacing it, simply install the clean non-woven fabric roll on one non-woven fabric drive base 2, pass the non-woven fabric 3 through the pressure roller 1 4, tension roller 6, and pressure roller 2 5 in sequence, and then fix the other end of the non-woven fabric 3 to the other non-woven fabric drive base 2.

[0028] The rubber mixing tube 7 is mounted on a three-axis motion mechanism of the glue coating device. Driven by the three-axis motion mechanism, the rubber mixing tube 7 moves along the three directions of the X axis, the Y axis, and the Z axis.

[0029] This invention features an automatic cleaning mechanism for the mixing hose tip, enabling automated cleaning without interrupting equipment operation. This reduces quality issues caused by residual or dried adhesive. This invention offers the advantages of shortened operation time, low cost, and an unaffected cleaning effect, effectively improving the overall equipment efficiency (OEE).

[0030] In the present invention, the cleaning method of the automatic cleaning mechanism of the mixing hose gun head includes the following steps: Step 1: According to the position signal of the tension roller 6 detected by the displacement sensor, the driving motor 21 is adjusted so that the non-woven fabric 3 is in a suitable position for cleaning the gun head 71 of the mixing tube 7.

[0031] Step 2: Move the mixing tube 7 to above the tensioning roller 6, adjust the Z-axis height of the mixing tube 7, lower the gun head 71 of the mixing tube 7 to the middle position between the pressing roller 1 4 and the pressing roller 2 5, and the pressing roller 1 4 and the pressing roller 2 5 move toward each other along the horizontal guide rail 8 until the non-woven fabric 3 wraps around the gun head 71 of the mixing tube 7. The pressing roller 1 4 and the pressing roller 2 5 stop and maintain the clamping pressure.

[0032] The clamping pressure is calculated based on the displacement change of the tension roller 6 detected by the displacement sensor to obtain a pressure value: pressure value = spring elastic coefficient × displacement change. The compression amount of spring 1 and spring 2 is manually adjusted according to the pressure value.

[0033] Step 3: The rotating mechanism rotates back and forth, and the non-woven fabric 3 cleans the gun head 71 of the mixing tube 7 360°. At the same time, the Z-axis height of the mixing tube 7 is adjusted, and the gun head 71 of the mixing tube 7 rises.

[0034] In step 4, after the gun head 71 of the mixing hose 7 leaves the pressing roller 1 4 and the pressing roller 2 5, the rotating mechanism stops reciprocating rotation, and the driving motor 21 rolls out the clean non-woven fabric and rolls the used non-woven fabric 3 into the discarded non-woven fabric roll.
