[0028] During operation, in the current prior art, although the screw can be taken out of the extruder by means of a hammer, the hammer needs to frequently strike the screw when taking the screw out, and frequent striking may cause damage to the screw and even damage to the extruder, thereby reducing the life of the screw and the extruder; when the device needs to clean the interior of the rotating rod 19, the spiral blade 191 and the heating tube 13, the pull rod 21 is moved to drive the insert rod 23 to disengage from the positioning block 18 and the rotating rod 19, thereby causing the rotating rod 19 to lose its fixation. After the rotating rod 19 loses its fixation, the rotating rod 19 can be taken out of the heating tube 13 without using a hammer to strike the rotating rod 19. The taking-out method is more convenient and concise, and the service life of the rotating rod 19 and the heating tube 13 is increased. After the rotating rod 19 and the spiral blade 191 are taken out, the rotating rod 19, the spiral blade 191 and the interior of the heating tube 13 can be cleaned.

[0029] Further, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the fixing assembly includes a U-shaped plate 2, and the U-shaped plate 2 is fixedly connected to the outside of the positioning block 18; a pull rod 21 is slidably connected to the middle of the U-shaped plate 2; a pull ring 22 is fixedly connected to the end of the pull rod 21 away from the positioning block 18; an insertion rod 23 is fixedly connected to the end of the pull rod 21 close to the positioning block 18; slots 25 are respectively provided at the positions of the positioning block 18 and the rotating rod 19 corresponding to the insertion rod 23, and the insertion rod 23 is inserted into the slots 25; a No. 1 spring 24 is fixedly connected to the inside of the U-shaped plate 2, and the other end of the No. 1 spring 24 is fixedly connected to the insertion rod 23; the No. 1 spring 24 is located on the outside of the insertion rod 23.

[0030] During operation, when it is necessary to clean the rotating rod 19, the spiral blade 191 and the inside of the heating tube 13, the staff pulls the pull ring 22, and the movement of the pull ring 22 drives the pull rod 21 to move, and the movement of the pull rod 21 drives the insertion rod 23 to disengage from the slot 25, so that the rotating rod 19 loses its fixation. After the rotating rod 19 loses its fixation, the rotating rod 19 can be taken out of the heating tube 13 without using a hammer to knock the rotating rod 19. The removal method is more convenient and simple, which improves the service life of the rotating rod 19 and the heating tube 13. After the rotating rod 19 and the spiral blade 191 are taken out, the rotating rod 19, the spiral blade 191 and the heating tube 13 can be cleaned. 3 is cleaned; when installing the rotating rod 19, the staff puts the rotating rod 19 into the heating tube 13 and pushes the rotating rod 19. When the rotating rod 19 contacts the plugging rod 23, the rotating rod 19 will squeeze the plugging rod 23. The plugging rod 23 will slide out of the positioning block 18 when squeezed, and squeeze the No. 1 spring 24. The No. 1 spring 24 will shrink when squeezed and give a thrust to the plugging rod 23. After the rotating rod 19 completely enters the positioning block 18, the rotating rod 19 is rotated to align the slot 25 with the position of the plugging rod 23. Under the action of the thrust of the No. 1 spring 24, the plugging rod 23 will be inserted into the slot 25, thereby fixing the rotating rod 19.

[0031] Further, such as Figure 5 and Figure 6 As shown, the insertion rod 23 has a first arc surface 26 at the position corresponding to the rotating rod 19 ; the rotating rod 19 has a second arc surface 27 at one end close to the insertion rod 23 , and the first arc surface 26 and the second arc surface 27 are used in conjunction with each other.

[0032] During operation, when the rotating rod 19 enters the interior of the positioning block 18 , the second arc surface 27 will first contact the first arc surface 26 , thereby facilitating the rotating rod 19 to squeeze the insertion rod 23 .

[0033] Further, such as Figure 7 As shown, a symmetrically arranged T-shaped plug 3 is fixedly connected to one side of the extrusion cylinder 17 close to the fixed plate 16 ; the fixed plate 16 is provided with symmetrically arranged T-shaped positioning grooves 31 for the positions of the T-shaped plug 3 , and the T-shaped plug 3 is inserted into the T-shaped positioning grooves 31 .

[0034] During operation, when installing the extrusion tube 17 , the installation of the extrusion tube 17 is completed by inserting the T-shaped plug block 3 of the extrusion tube 17 into the T-shaped positioning groove 31 of the fixing plate 16 .

[0035] Further, such as Figure 7As shown, a shell 4 is fixedly connected above the fixed plate 16; a symmetrically arranged No. 2 spring 41 is fixedly connected inside the shell 4; a stopper 42 is fixedly connected to the other end of the No. 2 spring 41, and the stopper 42 is slidably connected inside the shell 4; the stopper 42 is located above the T-shaped plug 3; a shift block 43 is fixedly connected above the stopper 42.

[0036] During operation, when it is necessary to install or remove the extruder barrel 17, the staff will pinch the two shift blocks 43 respectively to make the two shift blocks 43 approach each other. The movement of the shift block 43 drives the stop block 42 to slide into the shell 4. The stop block 42 enters the shell 4 and squeezes the No. 2 spring 41. The No. 2 spring 41 will shrink under the squeezing and give a thrust to the stop block 42. After the stop block 42 enters the shell 4, the extruder barrel 17 can be installed or removed. After the extruder barrel 17 is installed, the staff will slowly release the shift block 43. Under the thrust of the No. 2 spring 41, the stop block 42 slides out of the shell 4 and blocks above the T-shaped plug 3, so that the extruder barrel 17 can be fixed to prevent the extruder barrel 17 from shifting.

[0037] Further, such as Figure 7 As shown, a symmetrically arranged movable groove 44 is provided above the housing 4 for the position of the shift block 43 , and the shift block 43 is slidably connected in the movable groove 44 .

[0038] During operation, the movable groove 44 provided on the upper portion of the housing 4 allows the shifting block 43 to be slidably connected in the movable groove 44 , thereby limiting the position of the shifting block 43 .

[0039] Working principle:

[0040] When it is necessary to clean the rotating rod 19, the spiral blade 191 and the inside of the heating tube 13, the staff pulls the pull ring 22, and the movement of the pull ring 22 drives the pull rod 21 to move. The movement of the pull rod 21 drives the insertion rod 23 to disengage from the slot 25, so that the rotating rod 19 loses its fixation. After the rotating rod 19 loses its fixation, the rotating rod 19 can be taken out of the heating tube 13 without using a hammer to knock the rotating rod 19. The removal method is more convenient and simple, which improves the service life of the rotating rod 19 and the heating tube 13. After the rotating rod 19 and the spiral blade 191 are taken out, the rotating rod 19, the spiral blade 191 and the heating tube 13 can be cleaned. The interior is cleaned; when installing the rotating rod 19, the staff puts the rotating rod 19 into the heating tube 13 and pushes the rotating rod 19. When the rotating rod 19 contacts the insertion rod 23, the rotating rod 19 will squeeze the insertion rod 23. The insertion rod 23 will slide out of the positioning block 18 when squeezed, and squeeze the No. 1 spring 24. The No. 1 spring 24 will shrink when squeezed and give a thrust to the insertion rod 23. After the rotating rod 19 completely enters the positioning block 18, the rotating rod 19 is rotated to align the slot 25 with the position of the insertion rod 23. Under the action of the thrust of the No. 1 spring 24, the insertion rod 23 will be inserted into the slot 25, thereby fixing the rotating rod 19.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
