[0026] Example:

[0027] See also Figure 1 - Figure 5 The utility model provides a technical solution: a wood fiber particle extrusion device, comprising:

[0028] Tank 1;

[0029] A support leg 2, the inner wall of the support leg 2 is fixedly connected to the outer wall of the tank body 1;

[0030] A stepper motor 3, the outer wall of the stepper motor 3 is fixedly connected to the top of the tank body 1 through a frame;

[0031] A quick connection mechanism 5, the outer wall of the quick connection mechanism 5 is slidably connected to the inner wall of the tank body 1;

[0032] A mixing mechanism 4, the top of which is fixedly connected to the output end of the stepping motor 3;

[0033] The mixing mechanism 4 includes a screw rod 42, the outer wall of which is threadedly connected to an extrusion plate 41, and the bottom of the screw rod 42 is fixedly connected to an extrusion leaf 44 through a connecting disk 45. The extrusion leaf 44 is tilted at an angle so that the extrusion leaf 44 can extrude wood fibers during rotation, and the outer wall of the connecting disk 45 is fixedly connected to the outer wall of the extrusion leaf 44, the inner wall of the connecting disk 45 is slidably connected to a limiting column 43, the bottom of the limiting column 43 is fixedly connected to a limiting disk 46, the top of the limiting disk 46 contacts the bottom of the extrusion plate 41, and the outer wall of the limiting column 43 is fixedly connected to the outer wall of the tank body 1.

[0034] The outer wall of the extrusion leaf 44 is slidably connected to the inner wall of the tank body 1, the top of the screw rod 42 is fixedly connected to the output end of the stepper motor 3, and the quick-connect mechanism 5 includes a fixed disk 51, the top of the fixed disk 51 is fixedly connected to a mounting ring 52, the inner wall of the fixed disk 51 is fixedly connected to a discharge disk 53, the outer wall of the fixed disk 51 is fixedly connected to a fixed seat 55, and an annular array is formed along the central axis of the fixed disk 51. The inner wall of the fixed disk 51 is slidably connected to a limiting ball 54, and a groove is opened in the wall of the fixed seat 55 so that the limiting ball 54 can slide in the groove.

[0035] The outer wall of the limiting ball 54 is fixedly connected with a top spring 57, and the outer wall of the limiting ball 54 is fixedly connected with a pull column 56. The limiting ball 54 is slidably connected to the inner wall of the tank body 1 through the mounting groove 6, and the mounting groove 6 is opened in the wall of the tank body 1. The end of the top spring 57 away from the limiting ball 54 is fixedly connected to the inner wall of the fixing seat 55. Under the push of the top spring 57, the limiting ball 54 is always stuck in the positioning groove of the tank body 1 without the action of external force. The inner wall of the fixing seat 55 is slidably connected to the outer wall of the pull column 56, the outer wall of the mounting ring 52 is slidably connected to the inner wall of the tank body 1, and the top of the fixed plate 51 is in contact with the bottom of the tank body 1.

[0036] Working principle:

[0037] When in use, first place the extrusion device on the ground so that the support feet 2 on the tank body 1 are against the ground to support the position of the tank body 1, and then pour the wood fiber into the tank body 1 through the opening at the top of the tank body 1. It should be noted that when pouring the wood fiber, the wood fiber needs to be poured along the edge of the tank body 1 to prevent the wood fiber from falling on the mixing mechanism 4 and causing blockage of the wood fiber feed. After the wood fiber is poured, start the stepper motor 3 and drive the mixing mechanism 4 to rotate. During the rotation of the mixing mechanism 4, the wood fiber is first stirred and then squeezed, and then the wood fiber is pressed to the quick-connect mechanism 5, and then squeezed out of the equipment under the squeezing of the mixing mechanism 4.

[0038] After pouring the wood fiber into the tank body 1, the stepper motor 3 is started, and the stepper motor 3 drives the screw rod 42 to rotate. The bottom of the screw rod 42 is connected to the squeezing leaf 44 through the connecting plate 45, so the squeezing leaf 44 also rotates synchronously with the screw rod 42. Under the rotation of the squeezing leaf 44, the wood fiber is stirred. Because the squeezing plate 41 is threadedly connected to the screw rod 42, and a limiting column 43 is provided in the squeezing plate 41, the squeezing plate 41 is limited by the limiting column 43, so as to squeeze the wood fiber, so that the wood fiber on the top is forced to press the bottom of the tank body 1. The bottom of the limiting column 43 limits the sliding position of the squeezing plate 41 through the limiting plate 46, so as to prevent the squeezing plate 41 from sliding downward continuously and pressing the squeezing leaf 44. Under the continuous rotation of the squeezing leaf 44, the wood fiber at the bottom is forced to be squeezed to the quick connection mechanism 5, and then squeezed out of the tank body 1 through the quick connection mechanism 5, thereby completing the extrusion work.

[0039] Because the squeezing blades 44 are attached to the inner wall of the tank body 1, the inner wall of the tank body 1 is scraped synchronously during the rotation of the squeezing blades 44. Therefore, when there is not much wood fiber in the tank body 1, the squeezing blades 44 rotate to squeeze the wood fiber attached to the inner wall of the tank body 1 to the bottom of the tank body 1, so that the remaining wood fiber can be pressed out of the tank body 1.

[0040] When the coarseness of the wood fiber particles needs to be changed, the discharge tray 53 can be quickly replaced by the quick-connect mechanism 5, so as to quickly change the coarseness of the wood fiber particles. It is only necessary to pull the pull column 56 first to make the limit ball 54 exit the positioning groove on the tank body 1, and then rotate the fixed plate 51, so that the fixed plate 51 drives the fixed seat 55 to slide. During the sliding process of the fixed seat 55, the lock of the fixed seat 55 can be released. After the limit ball 54 slides into the installation groove 6, the pulling force on the pull column 56 can be released, and then the fixed plate 51 can be pulled out downward, so that the entire quick-connect mechanism 5 can be quickly replaced. The connecting mechanism 5 slides out of the tank body 1, and the new quick connecting mechanism 5 is aligned with the bottom of the tank body 1. The mounting ring 52 is slid into the tank body 1 along the inner wall of the tank body 1. It should be noted that the limiting ball 54 also needs to be aligned with the mounting groove 6. During the sliding process of the limiting ball 54 in the mounting groove 6, the top spring 57 is synchronously compressed so that the top spring 57 is compressed to accumulate elastic potential energy, and then the fixed disk 51 is rotated in the opposite direction, so that the limiting ball 54 slides back to the positioning groove, and then, under the push of the top spring 57, it slides back into the positioning groove to re-lock the position of the fixed disk 51.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
