Embodiment 2

[0039] Embodiment 2: a kind of PPR fuser, such as Figure 3 to Figure 5 As shown, the difference from Example 1 lies in: the detachable connection mode of the heat conduction sleeve 31 of the die paint surface and the hot-melt die 21, the detachable connection mode of the heat conduction sleeve 32 of the punch paint surface and the heat-melt punch 22 different.

[0040] Such as image 3 and Figure 4 As shown, the inner surface of the hot-melt die 21 is provided with three first sliding grooves 211 extending axially and distributed along its circumferential circumference, and the inner surface of the hot-melt die 21 is provided with three first slide grooves 211 along its circumferential direction. The first fastening slots 212 extend and respectively communicate with the three first slide slots 211 . The outer surface of the die paint surface heat conduction sleeve 31 is integrally formed with three heat conduction sleeves that move along the first chute 211 when the die p...

Embodiment 3

[0044] Embodiment 3: a kind of PPR fuser, such as Figure 6 As shown, the difference from Embodiment 1 is that: the hot-melt die 21 and the hot-melt punch 22 are detachably connected on the heating plate 11; The way, the detachable connection mode of the heat-conducting sleeve 32 of the punch paint surface and the hot-melt punch 22 are different.

[0045] Such as Figure 6 As shown, a through hole 111 is provided on the heating plate 11, a first installation hole 213 corresponding to the through hole 111 is provided on the hot-melt die 21, and a second installation hole corresponding to the through hole 111 is provided on the hot-melt punch 22 223 , a third installation hole 314 corresponding to the first installation hole 213 is opened at the bottom of the female mold paint surface heat conduction sleeve 31 , and a fourth installation hole 324 corresponding to the second installation hole 223 is opened at the bottom of the male mold paint surface heat conduction sleeve 32 . ...

Abstract

The invention discloses a PPR hot melt machine. The PPR hot melt machine comprises a main machine and a plurality of die heads arranged on a heating plate of the main machine, wherein each die head comprises a hot melt female die arranged on one side of the heating plate and a hot melt male die arranged on the other side of the heating plate; a female die paint surface heat conduction sleeve is detachably connected in each hot melt female die; a male die paint surface heat conduction sleeve is detachably connected to each hot melt male die; and a paint surface coating is respectively arrangedon inner surface of each female die paint surface heat conduction sleeve and on outer surface of each male die paint surface heat conduction sleeve. The PPR hot melt machine has the advantages and effects that each hot melt female die and each hot melt male die of each die head are respectively provided with a detachable female die paint surface heat conduction sleeve and a male die paint surfaceheat conduction sleeve, the inner surface of each female die paint surface heat conduction sleeve and the outer surface of each male die paint surface heat conduction sleeve are each provided with a paint surface coating, so that only the female die paint surface heat conduction sleeves and the male die paint surface heat conduction sleeves need to be replaced after the paint surface coatings areworn, and the service life of the paint surface coatings on the die heads are prolonged.

Description

technical field [0001] The invention relates to the technical field of pipe processing equipment, in particular to a PPR hot melter. Background technique [0002] PPR hot melter is a welding tool used for heating and melting thermoplastic pipes and pipe fittings and then connecting them. The PPR hot melter mainly includes two parts: the main machine and the die head. The hot-melt concave die and the hot-melt punch of the die head are installed on both sides of the heating plate of the main machine. On the mold and hot-melt punch, after the temperature of the hot-melt die and the hot-melt punch of the die head reach the welding temperature, they are used to melt the surrounding side of the pipe and the inside of the pipe fitting respectively, and insert the pipe into the pipe fitting at high temperature. Welding is completed after cooling. [0003] The connection mode of the host machine and the die head can be divided into detachable type and integrated type. When the mai...
