The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0029] Example 1

[0030] Reference Figures 1-5 This is the first embodiment of the present invention, which provides a PE pipe extruder, comprising,

[0031] The extrusion device 100 includes a base 101, a tube 102 installed at the middle position of the upper end of the base 101, a screw 103 rotatably installed inside the tube 102, and a mold 104 installed at the end of the tube 102. A hopper 105 is bolted to the upper end of the tube 102 and communicates with the inside of the tube 102.

[0032] The protective device 200 includes a support base 201, a housing 202 mounted on the upper end of the support base 201, and a sleeve 203 rotatably mounted inside the housing 202. The support base 201 is slidably connected to the upper end of the base 101, and the sleeve 203 is sleeved on the end of the mold 104, with a through hole structure whose center position of the side wall of the sleeve 203 matches the discharge port of the mold 104.

[0033] The tube 102 with a screw 103 is mounted on the base 101. The hopper 105 is used to add the material to be extruded into the tube 102. The material is conveyed by the screw 103 towards the mold 104 mounted at the end of the tube 102. After being extruded by the mold 104, it is cooled into a tube by the forming die and conveyed to the downstream equipment. A sleeve 203 with a shell 202 is installed at the end of the base 101. The shell 202 is used to shield and protect the mold 104, reduce the impact of the external environment on the mold 104, and slow down the heat loss of the mold 104, so that the mold 104 can stably extrude material and maintain P. For E-tube forming quality, the sleeve 203 connects with the mold 104, further protecting the mold 104. The locking mechanism secures the mold 104 within the sleeve 203. Rotating the sleeve 203 along the outer shell 202 allows the mold 104 to rotate, facilitating its connection and installation with the extruder. It also facilitates removal of the mold 104 from the extruder end for cleaning and maintenance. Furthermore, the sleeve 203, together with the outer shell 202, insulates the mold 104 from most of its heat, allowing for disassembly and assembly even at high temperatures, reducing downtime for maintenance and minimizing material waste.

[0034] Specifically, a locking block 204 is slidably installed on the side wall of the sleeve 203. One end of the locking block 204 is locked onto the side wall of the mold 104, and the side wall of the mold 104 has a slot structure that matches the end of the locking block 204.

[0035] Specifically, a locking block 204 is installed on the side wall of the sleeve 203, and the locking block 204 is snapped onto the side wall of the mold 104. The locking block 204 is then fixed in place, which can limit the position of the mold 104 based on the installation of the sleeve 203, and maintain the stability of the position of the mold 104.

[0036] Furthermore, a turntable 205 is rotatably installed inside the sleeve 203, and the side wall of the locking block 204 is provided with teeth that mesh with the turntable 205. A connector 206 is rotatably installed on the side wall of the sleeve 203, and one end of the connector 206 is meshed with the other side of the turntable 205.

[0037] Inside the sleeve 203, a turntable 205 is installed to connect with a connector 206 and a locking block 204. By rotating the connector 206, the position of the locking block 204 can be adjusted from the outside of the sleeve 203 in conjunction with the turntable 205. This allows the sleeve 203 to clamp the mold 104, or to loosen the mold 104 from the middle of the sleeve 203 for disassembly and maintenance. The turntable 205 can also limit the locking block 204, keeping it stably engaged on the outside of the mold 104 and preventing it from loosening.

[0038] Furthermore, the other end of the connector 206 is provided with a positioning hole, and the side wall of the housing 202 is provided with an adjustment hole 207 that matches the positioning hole on the side wall of the connector 206.

[0039] In this design, an adjustment hole 207 is added to the side wall of the outer shell 202. When the mold 104 is rotated by the sleeve 203 and the positioning hole on the side wall of the sleeve 203 is aligned with the adjustment hole 207, a wrench or other component is inserted from the side wall of the adjustment hole 207 and aligns with the positioning hole on the side wall of the sleeve 203. This allows the connecting piece 206 on the side wall of the sleeve 203 to be rotated from the outside of the outer shell 202. In turn, the connecting piece 206 is rotated by the turntable 205 to adjust the connection state between the sleeve 203 and the mold 104.

[0040] Preferably, a handle 208 is rotatably mounted on one side of the middle of the outer casing 202. The handle 208 is engaged with the outer wall of the sleeve 203, and the end of the handle 208 is provided with a tooth structure that matches the tooth structure of the worm gear rack on the outer side of the sleeve 203.

[0041] Specifically, a handle 208 is installed on the side wall of the outer shell 202 to connect with the sleeve 203. A turbine structure is added to the outer wall of the sleeve 203. The end of the handle 208 is set as a worm gear structure. Rotating the handle 208 can drive the sleeve 203 to rotate synchronously, thereby rotating the mold 104 installed in the middle of the sleeve 203, locking the mold 104, or removing the mold 104 from the end of the extruder. At the same time, it can prevent the sleeve 203 from reversing and keep the rotation angle of the mold 104 stable.

[0042] Preferably, the support base 201 has a handle bolt 209 threadedly connected to its side wall, and the end of the handle bolt 209 passes through the support base 201 and contacts the base 101.

[0043] Specifically, a handle bolt 209 is installed on the side wall of the support base 201 and connected to the base 101. Loosening the handle bolt 209 allows for easy adjustment of the position of the support base 201 along the base 101, thereby adjusting the mounting components of the mold 104 for easy connection with the extruder. Tightening the handle bolt 209 fixes the support base 201 above the base 101, maintaining the stability of the position of components such as the mold 104.

[0044] Specifically, a motor 106 is bolted to one end of the base 101, and the output shaft of the motor 106 is connected to the screw 103 via a reducer.

[0045] A motor 106 is installed at the end of the base 101. The power supply of the motor 106 is turned on by the control device. The motor 106 drives the screw 103 to rotate through the reducer, which conveys the material added into the tube 102 forward and extrudes the material outward through the mold 104.

[0046] Preferably, an electric heating coil 107 is sleeved on the outside of the tube body 102, and a cover plate 108 is installed in the middle of the base 101, with the cover plate 108 sleeved on the outside of the electric heating coil 107.

[0047] Among them, an electric heating ring 107 with a cover plate 108 is installed on the outer wall of the pipe body 102. The electric heating ring 107 is used to assist in heating the pipe body 102, keeping the PE pipe material conveyed inside the pipe body 102 in a molten state, so as to facilitate extrusion molding through the mold 104 and keep the pipe material uniformly formed. The cover plate 108 is used to shield and protect the components of the extruder, prevent the staff from accidentally touching the high temperature area, and keep the equipment operating safely.

[0048] In summary, a tube 102 with a screw 103 is installed on the base 101. The hopper 105 is used to add the material to be extruded into the tube 102. The material is conveyed by the screw 103 towards the mold 104 installed at the end of the tube 102. After being extruded by the mold 104, it is cooled into a tube by the forming die and conveyed to the downstream equipment. A sleeve 203 with a shell 202 is installed at the end of the base 101. The shell 202 is used to shield and protect the mold 104, reduce the influence of the external environment on the mold 104, and slow down the heat loss of the mold 104, so that the mold 104 can stably extrude the material and maintain P. For E-tube forming quality, the sleeve 203 connects with the mold 104, further protecting the mold 104. The locking mechanism secures the mold 104 within the sleeve 203. Rotating the sleeve 203 along the outer shell 202 allows the mold 104 to rotate, facilitating its connection and installation with the extruder. It also facilitates removal of the mold 104 from the extruder end for cleaning and maintenance. Furthermore, the sleeve 203, together with the outer shell 202, insulates the mold 104 from most of its heat, allowing for disassembly and assembly even at high temperatures, reducing downtime for maintenance and minimizing material waste.
