[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses an extruder barrel that is easy to clean. For example... Figure 1 and Figure 2 The easy-to-clean extruder barrel includes a barrel body disposed on a base 1. The barrel body includes a lower barrel 11 fixedly installed on the base 1 and an upper barrel 12 detachably installed above the lower barrel 11.

[0031] like Figure 1 and Figure 3 The upper cylinder 12 is movably mounted on the base 1, allowing it to rotate relative to the lower cylinder 11. A bracket 41 is fixedly connected to the base 1, and one end of the upper cylinder 12 is hinged to the bracket 41. To control the rotation of the upper cylinder 12, a rotation assembly 4 is also provided on the base 1. The rotation assembly 4 includes a movable seat 42 vertically slidably mounted on the bracket 41. A second control unit 5 for controlling the raising and lowering of the movable seat 42 is provided on the bracket 41. A linkage rod 52 is hinged to the movable seat 42, with the end of the linkage rod 52 away from the movable seat 42 hinged to the upper cylinder 12. The raising and lowering of the movable seat 42 drives the upper cylinder 12 to rotate via the linkage rod 52.

[0032] The second control unit 5 includes a hydraulic cylinder 51 mounted on a bracket 41, with the piston rod of the hydraulic cylinder 51 fixedly connected to a movable seat 42. When the piston rod of the hydraulic cylinder 51 extends or retracts, it can drive the movable seat 42 to rise or fall, thereby driving the upper cylinder 12 to rotate via the linkage rod 52.

[0033] The lower barrel 11 is slidably mounted on the base 1 via a lifting assembly 2. The lifting assembly 2 includes a first connecting rod 21 and a second connecting rod 22. One end of the first connecting rod 21 is hinged to the bottom wall of the lower barrel 11, and the end of the first connecting rod 21 away from the lower barrel 11 is hinged to a slide block 23, which is slidably mounted on a slide rail on the base 1. One end of the second connecting rod 22 is hinged to the base 1, and the end of the second connecting rod 22 away from the base 1 is rotatably connected to a slide rod 24, which is slidably mounted on a slide rail on the bottom wall of the lower barrel 11. The axial distance between the hinge axes of the two ends of the first connecting rod 21 is the same as the axial distance between the hinge axes of the two ends of the second connecting rod 22, and the middle positions of the first connecting rod 21 and the second connecting rod 22 are hinged to each other via a pivot. To control the movement of the slide block 23, a first control unit 3 is also provided on the base 1.

[0034] like Figure 1 and Figure 4The first control unit 3 includes a second stud 31 rotatably connected to the base 1. The second stud 31 passes through the slide 23 and is threadedly connected to the slide 23. A drive motor 32 is fixedly connected to the base 1, and the output shaft of the drive motor 32 is drivenly connected to one end of the second stud 31 through a coupling. When the drive motor 32 starts, it can drive the second stud 31 to rotate, thereby driving the slide 23 to slide along the slide rail through the threaded connection. As the slide 23 moves, the included angle between the first connecting rod 21 and the second connecting rod 22 changes, thereby driving the lower barrel 11 to rise and fall.

[0035] To ensure the stability of the barrel body during extruder operation, a limit rod 6 is hinged to the base 1. When the lower barrel 11 is in the raised state, the limit rod 6 can flip to abut against the slide 23, thereby restricting the movement of the slide 23. Furthermore, the slide 23 is provided with a slot 61 for the limit rod 6 to be inserted into, and a trigger switch 62 is installed within the slot 61. When the limit rod 6 is inserted into the slot 61 and abuts against the trigger switch 62, the trigger switch 62 sends a power-off signal to the drive motor 32, causing the drive motor 32 to stop working. When it is necessary to move the lower barrel 11, simply pull the limit rod 6 out of the slot 61, the trigger switch 62 resets, and the drive motor 32 is energized and can start working under the control of the controller.

[0036] To facilitate quick assembly and disassembly between the upper barrel 12 and the lower barrel 11, a first stud 14 is hinged to the side wall of the lower barrel 11, and a nut 15 is threaded onto the first stud 14. A groove 13, which mates with the first stud 14, is provided on the side wall of the upper barrel 12. When the upper barrel 12 needs to be installed on the lower barrel 11, simply insert the first stud 14 into the groove 13, and then rotate the nut 15 on the first stud 14 to press the upper barrel 12 against the lower barrel 11. When the upper barrel 12 needs to be disassembled, simply rotate the nut 15 in the opposite direction to release the nut from its pressing effect on the upper barrel 12, thus disengaging the connection between the upper barrel 12 and the lower barrel 11.

[0037] The working principle of this embodiment is as follows: When it is necessary to clean the inside of the barrel, first loosen the nut 15 and flip the first stud 14 to disconnect the connection between the upper barrel 12 and the lower barrel 11. Then, by flipping the limit rod 6, the limiting effect of the limit rod 6 on the slide 23 is released. In this state, the trigger switch 62 is reset, so that the drive motor 32 is energized and the controller can control the drive motor 32 to work.

[0038] The operator activates hydraulic cylinder 51, which, via linkage rod 52, rotates upper barrel 12 to a certain angle. Then, the drive motor 32 is activated, and through the threaded connection between second stud 31 and slide block 23, lower barrel 11 descends, separating the screw inside the lower barrel 11. This allows the operator to clean the screw and the inside of the barrel. After cleaning, the lower barrel 11 is raised, and upper barrel 12 is rotated back to its original position. The upper barrel 12 is then secured to lower barrel 11 using first stud 14 and nut 15. Finally, the limiting rod 6 is re-engaged into slot 61.

[0039] In summary, the extruder barrel body in this embodiment achieves the tilting of the upper barrel 12 and the lifting of the lower barrel 11 through the design of the lifting assembly 2 and the tilting assembly 4, thereby simplifying the cleaning process inside the barrel and improving the ease of equipment maintenance. Meanwhile, the lifting assembly 2, using a linkage mechanism and a drive motor 32, achieves stable lifting of the lower barrel 11; the tilting assembly 4 uses a hydraulic cylinder 51 as a power source, and achieves the tilting of the upper barrel 12 through a linkage rod 52, making operation simple, stable, and reliable; the lower barrel 11 and the upper barrel 12 are connected by a first stud 14 and a nut 15, enabling quick disassembly and assembly, facilitating cleaning and maintenance of the barrel body.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
