[0031] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides an automatic wiping nozzle module, including a bracket 1. The bracket 1 includes a vertical frame 20 and a horizontal frame 21 bolted to the upper end of the vertical frame 20. The horizontal frame 21 is perpendicular to the vertical frame 20.

[0032] The feeding shaft 2 is rotatably mounted on the front side of the cross frame 21. A damper 14 is bolted to the rear side of the cross frame 21. The damping shaft of the damper 14 is connected to the feeding shaft 2. The damper 14 is used to provide motion resistance for the rotation of the feeding shaft 2. A material strip roll 3 formed by winding the wiping cloth 4 is provided on the feeding shaft 2.

[0033] The receiving shaft 5 is rotatably mounted on the front side of the cross frame 21, wherein the axes of the feeding shaft 2 and the receiving shaft 5 are located on the same horizontal line;

[0034] The adhesive wiping platform 6 is set on the crossbeam 21 between the feeding shaft 2 and the receiving shaft 5, wherein the setting height of the adhesive wiping platform 6 is higher than the setting height of the feeding shaft 2 and the receiving shaft 5; the bracket 1 is provided with a drive component 11 that drives the receiving shaft 5 to rotate so that the adhesive wiping cloth 4 is wound onto the receiving shaft 5 after passing through the adhesive wiping platform 6; in this embodiment, the drive component 11 is a motor, which is bolted to the rear side of the crossbeam 21 and the output shaft of the motor is fixedly connected to the receiving shaft 5.

[0035] Please see Figure 1 , Figure 2 and Figure 3 A tensioning wheel 15 and a support roller 16 are rotatably mounted on a crossbeam 21 located between the wiping platform 6 and the take-up roller. The tensioning wheel 15 is used to increase the tension of the wiping cloth 4; the support roller 16 is used to support the wiping cloth 4. The tensioning wheel 15 is closer to the wiping platform 6 and its height is lower than that of the wiping platform 6. The support roller 16 is closer to the take-up shaft 5 and its height is higher than that of the take-up shaft 5. The support roller 16 is also higher than the tensioning wheel 15.

[0036] One end of the tensioning wheel 15 is bolted with a sensing plate 17, which is located on the rear side of the cross frame 21. A first sensor 18 is bolted on the rear side of the cross frame 21. When the tensioning wheel 15 rotates, it can drive the sensing plate 17 to rotate. The sensing plate 17 and the first sensor 18 work together to monitor the number of rotations of the tensioning wheel 15, and then monitor and control the length of the wiping cloth 4 that is driven forward.

[0037] A second sensor 19 is bolted to the crossbeam 21 located below the adhesive wiping platform 6. The second sensor 19 is tilted and can detect whether there is adhesive wiping cloth 4 being conveyed between the adhesive wiping platform 6 and the support roller 16. When the material roll 3 on the feeding shaft 2 is used up, the second sensor 19 can detect that there is no adhesive wiping cloth 4 being conveyed between the adhesive wiping platform 6 and the support roller 16, which can remind the staff to replenish the material roll 3.

[0038] Please see Figure 4 and Figure 5The adhesive application platform 6 includes a support frame 61 mounted on the bracket 1, a sponge block 62 mounted on the support frame 61, and two pressure shafts 63. The support frame 61 includes a pad 611 fixed to the top of the crossbeam 21 and a support frame 612 bolted to the pad 611. A rubber block 10 is bolted to the pad 611, and the rubber block 10 has a mounting groove in its center. The sponge block 62 is embedded in the mounting groove, and the thickness of the sponge block 62 is greater than the depth of the mounting groove. The support frame 612 frames the rubber block 10 and the sponge block 62 within it. The two pressure shafts 63 are located on either side of the sponge block 62, and the two pressure shafts 63 rotate independently. It is connected inside the support frame 612; both sides of the support frame 612 are provided with opening slots 24; one end of the wiping cloth 4 on the tape roll 3 enters the support frame 612 through the opening slot 24 on one side, passes through the bottom of the pressure shaft 63, goes around the sponge block 62, and then passes out through the bottom of the other pressure shaft 63 and out through the other opening slot 24; this design allows the wiping cloth 4 to be laid on the sponge block 62 for conveying, wherein the sponge block 62 is made of soft material, when the spray nozzle wipes the wiping cloth 4 on the wiping platform 6, the spray nozzle presses down on the wiping cloth 4 and sinks into the sponge block 62, thereby increasing the wiping area of ​​the spray nozzle and the wiping effect is better.

[0039] A fixing frame 12 is bolted to the cross frame 21 near the feeding shaft 2. A glue receiving hopper 13 is installed on the fixing frame 12. The glue receiving hopper 13 is used to collect the residual glue inside the glue spray nozzle.

[0040] Brief description of the usage process: First, the glue nozzle moves above the glue receiving hopper 13 and sprays glue to remove excess glue from the nozzle; then the glue nozzle moves to the wiping platform 6, presses down on the wiping cloth 4 and sinks into the sponge block 62, the drive component 11 drives the receiving shaft 5 to rotate, thereby pulling the wiping cloth 4 to drive, and the wiping cloth 4 wipes the glue nozzle on the wiping platform 6 clean during the transmission process.

[0041] In summary, in this invention, the tape roll 3 is mounted on the feeding shaft 2. One end of the wiping cloth 4 on the tape roll 3 wraps around the wiping platform 6 and then onto the take-up shaft 5. When the nozzle needs wiping, it moves onto the wiping platform 6. The driving component 11 drives the take-up shaft 5 to rotate, thereby pulling the wiping cloth 4. During the transmission process, the wiping cloth 4 cleans the nozzle on the wiping platform 6, achieving automatic wiping of the nozzle and improving the automation level of the dispensing machine. Furthermore, it reduces manual operation, achieving automatic cleaning of the nozzle and improving cleaning efficiency. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
