DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0021] See also Figures 1 to 5In this embodiment, a PE corrugated pipe extrusion screw barrel is provided, including a barrel body 1 and a regulating motor 2, wherein an adjusting screw 11 is arranged in the barrel body 1, and a regulating motor 2 is installed on the right end face of the adjusting screw 11, a feed port 13 is installed on the upper end face of the outer wall of the barrel body 1, and a discharge port 14 is installed on the left end face of the barrel body 1, a through hole is arranged above the discharge port 14, and a fixed pipe 15 is arranged in the through hole, and a plurality of circular holes are opened at the bottom of the outer wall of the fixed pipe 15, and a nozzle 16 is installed in the circular hole, and a water tank 17 is arranged behind the fixed pipe 15. When working, During the production of corrugated pipes, the material enters the barrel body 1 through the feed port 13, the regulating motor 2 is started, driving the adjusting screw 11 to rotate, and the material is extruded and discharged through the discharge port 14. Since the surface of the adjusting screw 11 is uneven, the broken materials are easily stuck on the outer wall of the adjusting screw 11 and difficult to clean, and the barrel body 1 is difficult to disassemble. At this time, the fixed pipe 15 is driven to move right, so that the fixed pipe 15 is inserted into the barrel body 1, the water tank 17 is filled with clean water, the nozzle 16 is opened, and the clean water is sprayed out to clean the surface of the adjusting screw 11 to ensure the cleaning effect.

[0022] A connecting pipe 12 is installed on the front end face of the water tank 17, a water pump 18 is installed on the outer wall of the connecting pipe 12, a spring tube 19 is installed on the other end of the connecting pipe, and a fixed pipe 15 is installed on the other end of the spring tube 19. When working, the water pump 18 starts to input the water in the water tank 17 into the spring tube 19, and then into the fixed pipe 15. The spring tube 19 structure is adopted to facilitate the moving of the fixed pipe 15, and there is no need to carry the water tank 17.

[0023] A control panel 21 is installed on the left end surface of the water tank 17. The control panel 21 is electrically connected to the nozzle 16. When working, a PLC program is written in the control panel 21 to control the valve of the nozzle 16 to open, so that the nozzle 16 works normally.

[0024] A first clamp 22 is installed on the right end face of the fixed tube 15, and a first clamping groove 23 cooperating therewith is opened on the right end face of the barrel body 1. During operation, when the fixed tube 15 moves to the right, the first clamp 22 is clamped into the first clamping groove 23, thereby fixing the right end part of the fixed tube 15 to ensure the stability of the nozzle 16.

[0025] A connecting frame is installed on the upper end face of the barrel body 1, and a ring sleeve is installed on the left end face of the connecting frame. A limiting screw 24 is threadedly connected to the inner side wall of the ring sleeve, and a limiting cavity 25 is installed on the upper end of the outer side wall of the fixed tube 15. The interior of the limiting cavity 25 is a threaded structure. When working, the limiting screw 24 is rotated to drive it to move downward, so that the limiting screw 24 enters the limiting cavity 25, thereby fixing the left end part of the fixed cavity, further ensuring the stability of the nozzle 16 when working.

[0026] The outer wall of the barrel body 1 is provided with a glass sleeve 26. When the machine is in operation, the glass sleeve 26 structure is used to facilitate the observation of the surface cleanliness of the adjusting screw 11, thereby performing a fixed-point spray cleaning process.
