A reciprocating screw rod 6 is rotatably connected to the inner wall of the box body 1, and a scraper 17 is passed through the reciprocating screw rod 6 and is threadedly connected thereto. The scraper 17 is slidably connected to the inner wall of the box body 1, a slide groove 16 is opened at the bottom end of the box body 1, a slider 19 is slidably connected in the slide groove 16, and the top of the slider 19 is fixedly connected to the scraper 17, and discharge ports 18 are opened at both ends of the slide groove 16. A discharge valve 8 is installed at the bottom of 18, heating plates 14 are fixedly installed on both sides of the inner wall of the box body 1, and guide grooves 20 are penetrated on both sides of the outer wall of the scraper 17 corresponding to the heating plates 14, and the guide grooves 20 are in contact with the outer wall of the heating plate 14. A transmission mechanism 21 is provided on the outer wall of the rotating shaft 11, and the rotating shaft 11 synchronously drives the reciprocating screw 6 to rotate through the transmission mechanism 21. The transmission mechanism 21 includes a transmission wheel 211 fixedly connected to the rotating shaft 11 and the outer wall of the reciprocating screw 6, and a belt 212 is sleeved between the transmission wheels 211. The reciprocating screw 6 penetrates the side wall of the box body 1 and is rotatably connected thereto. During the rotation of the rotating shaft 11, the reciprocating screw 6 is driven to rotate through the belt 212, and then the scraper 17 and the slider 19 are driven to move along the slide groove 16. The box 1 is moved repeatedly to scrape off the liquid adhering to the inner wall of the box body 1 and the outer wall of the heating plate 14. First, the discharge rate of the PP material and the auxiliary material after liquefaction is improved to save raw materials. Second, the liquid is prevented from adhering to the heating plate 14, which affects the heating efficiency of the heating plate 14 and causes the discharge quality to be substandard. The top of the box body 1 is fixedly connected with a material box 3, and a feed trough 12 is penetrated between the material box 3 and the box body 1. A slide plate 13 is slidably connected to the inner wall of the material box 3. One side of the top of the material box 3 is connected to a main feed hopper 5, and the other side of the top of the material box 3 is connected to a plurality of auxiliary feed hoppers 4. The end of the slide plate 13 corresponds to the main feed hopper 5 and is penetrated by a main material trough 22, and the end of the slide plate 13 corresponds to the auxiliary feed hopper 4 and is penetrated by auxiliary material troughs 2 4.

The heating plate 14 and the motor 7 are connected. The motor 7 drives the rotating shaft 11 and the stirring rod 15 to rotate to stir the PP material and the auxiliary materials. At the same time, the heating plate 14 heats the mixed material until it is completely liquefied. After it is connected to the discharge valve 8, it is discharged from the box body 1 from the discharge port 18, thereby realizing automatic quantitative addition of the PP material and the auxiliary materials, saving time and labor and improving the production efficiency of the strapping tape.

It should be noted that the main material trough 22 and the auxiliary material trough 24 are respectively set according to the ratio of PP material and auxiliary material. After the PP material and the auxiliary material are completely filled into the main material trough 22 and the auxiliary material trough 24, the cylinder 2 is connected to drive the slide plate 13 to move toward the feed trough 12, so that the PP material and the auxiliary material enter the box body 1, and the heating plate 14 and the motor 7 are connected. The motor 7 drives the rotating shaft 11 and the stirring rod 15 to rotate, and the PP material and the auxiliary material are stirred. At the same time, the heating plate 1 4 heats the mixed material until it is completely liquefied, and then discharges it from the discharge port 18 of the box body 1 through the connection discharge valve 8. During the rotation of the rotating shaft 11, the reciprocating screw 6 is driven to rotate by the belt 212, and then the scraper 17 and the slider 19 are driven to reciprocate along the slide 16 to scrape off the liquid adhering to the inner wall of the box body 1 and the outer wall of the heating plate 14. Firstly, the discharge rate of the PP material and the auxiliary material after liquefaction is improved to achieve the purpose of saving raw materials, and secondly, the liquid is prevented from adhering to the heating plate 14, which affects the heating efficiency of the heating plate 14 and causes the discharge quality to be substandard.
