[0031] The outer casing is disposed on the main body of the machine body, and the positioning carrier is disposed on the main body of the machine body. The first positioning groove for placing and positioning the PET strip 16 is disposed on the top surface of the positioning carrier, and the second positioning groove for placing and positioning the arc-shaped end cap 17 is disposed on the side wall of the positioning carrier at one end of the first positioning groove, and the first positioning groove and the second positioning groove are connected. The shaping and winding column for shaping and positioning the PET strip is disposed on the top surface of the positioning carrier at the other end of the first positioning groove. The clamping component is disposed on the side of the first positioning groove to clamp and fix the PET strip.

[0032] More preferably, the clamping assembly includes a clamping plate 7, a rotating connecting seat 8, and a rotating return spring. The rotating connecting seat is disposed on the positioning carrier. The clamping plate is movably connected to the rotating connecting seat via a rotating shaft. One end of the clamping plate extends above the first positioning groove, and a rotating return spring is connected between the clamping plate and the rotating connecting seat / positioning carrier to clamp or loosen the PET belt.

[0033] More preferably, the bottom surfaces at both ends of the first positioning groove are provided with high-temperature resistant plates 9. The high-temperature resistant plates can be made of high-temperature resistant synthetic stone or other materials to prevent poor heating effect when heating the PET strip due to excessively fast heat conduction.

[0034] Preferably, the shaping and winding column and the positioning carrier are detachably connected, so that their position and angle can be adjusted according to actual usage needs, thereby improving versatility.

[0035] The lifting drive mechanism drives the hot melt pressurizing assembly to move up and down, so that the hot melt pressurizing assembly can hot melt pressurize and fix the connection between the two ends of the folded PET strip.

[0036] The hot melt pressurizing assembly includes a lifting connecting plate 10, a heating mechanism, a pressure plate 11, and a pressing head 12. Two pressing heads that contact the PET belt are respectively disposed at both ends of the pressure plate. The heating mechanism is connected to the lifting connecting plate and the pressure plate to heat the pressing heads.

[0037] More preferably, the heating mechanism includes a resistance thermometer 13 and a thermocouple 14.

[0044] Step 2: Place the product end cap in the second positioning groove, press the end of the clamping plate, the clamping plate rotates and the first end of the clamping plate opens away from the first positioning groove, place the PET strip in the first positioning groove, pass one end of the PET strip through the perforation on the product end cap and then wrap it back to the top of the first positioning groove, and then wrap the other end around the shaping winding post and back to the top of the first positioning groove. Then release the clamping plate so that the clamping plate presses the end of the PET strip onto the PET strip in the first positioning groove.

[0045] Step 3: The lifting drive mechanism drives the hot melt pressurizing component to descend, so that the press head presses against the folded PET strip and its ends. The heating resistor heats the press head to melt and connect the processing position of the PET strip. After the pressing time lasts for 120 seconds, the cylinder automatically rises.

[0046] Step 4: After completion, the alarm will sound automatically, indicating that the pressing is complete. Repeat this production process.
