Description
Technical Field
[0001] This utility model relates to the field of granulator technology, specifically a wet extrusion granulator for trace element additives. Background Technology
[0002] In the production process of trace element additives, raw materials are extruded into granules through extrusion holes. After each use, the raw materials clogging the extrusion holes need to be cleaned. If not cleaned in time, the raw materials may accumulate and solidify, leading to problems such as equipment blockage and wear. Timely cleaning is necessary to ensure the stability and reliability of the equipment operation.
[0003] Existing technology uses a blocking plate to clean the extrusion holes as a whole. Specifically, the protruding metal block on the blocking plate inserts into the extrusion holes of the discharge plate, pushing out the raw material in the extrusion holes and cleaning each extrusion hole simultaneously, thus improving cleaning efficiency. However, in actual operation, relying solely on the blocking plate to clean the extrusion holes is significantly insufficient in terms of cleanliness, and some raw material will remain on the discharge plate. This residual material will adversely affect the subsequent production process. Furthermore, the traditional machine cover has a relatively simple function, only having the basic functions of opening and closing, which cannot meet diverse production needs. Utility Model Content

[0007] Preferably, a rotating shaft seat is fixedly connected to one side of the housing, and a shaft rod is rotatably connected inside the shaft hole of the rotating shaft seat. A rotating plate is sleeved on the circumferential side of the shaft rod. The rotating shaft seat and the rotating plate are rotatably connected through the shaft rod.

One of the T-shaped limiting members is slidably connected to the slot of the rotating plate, and the other T-shaped limiting member is slidably connected to the slot of the connecting seat through the movement of the housing cover.
[0008] Preferably, two trapezoidal locking blocks slide through the inner cavity of the T-shaped limiting member. The two trapezoidal locking blocks are symmetrically arranged in the inner cavity of the T-shaped limiting member. Several slots are provided at the slot of the rotating plate and the slot of the connecting seat. The trapezoidal locking blocks are engaged with the slots by sliding.
[0009] Preferably, a trapezoidal extrusion block is fixedly connected to one end of the pressing member that extends into the T-shaped limiting member.

[0010] Preferably, a square guide rod is fixedly connected to one side of the mounting plate, and an L-shaped rocker arm is fixedly connected to one side of the square guide rod. The square guide rod slides through the side wall of the plug component. A bearing is fixedly connected inside the outer shell of the cover, and the inner ring of the bearing is fixedly connected to the peripheral side of the plug component.
[0011] Preferably, a plurality of insert rods are fixedly connected to one side of the mounting plate, and an insertion hole adapted to the insert rods is opened on one side of the outer shell of the cover. The insert rods slide through the corresponding opening of the plug and are inserted into the insertion hole.
[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model proposes a wet extrusion granulator for trace element additives. During use, by aligning the plug pipe with the extrusion orifice and pulling the machine cover back and forth, the inside of the extrusion orifice can be directly cleaned, effectively removing raw materials clogging it and ensuring unobstructed flow. This guarantees the normal operation of the equipment and avoids product quality problems or equipment malfunctions caused by extrusion orifice blockage. A brush sliding inside the plug pipe cleans the discharge plate by rotating the plug. The brush can contact the surface of the discharge plate from all directions and at multiple angles, removing residual raw materials. Timely cleaning of the extrusion orifice and discharge plate prevents raw material accumulation and solidification, avoiding equipment blockage and wear caused by residual materials. This also prevents residual materials from affecting the quality of the next production run. After cleaning, a specific operation completely covers the discharge plate, effectively preventing external debris from entering the equipment and avoiding damage to internal parts or affecting normal operation, further protecting the equipment.

A mounting plate 603 is provided, with a brush 602 fixedly connected to one side of the mounting plate 603. A plug tube 6011 is slidably inserted into an extrusion hole 401. A square guide rod 604 is fixedly connected to one side of the mounting plate 603, and an L-shaped rocker arm 605 is fixedly connected to one side of the square guide rod 604. The square guide rod 604 slides through the side wall of the plug 601. A bearing 106 is fixedly connected inside the outer shell of the cover 5, and the inner ring of the bearing 106 is fixedly connected to the circumferential side of the plug 601. Several insert rods 606 are fixedly connected to one side of the mounting plate 603. An insertion hole 107 adapted to the insert rod 606 is opened on one side of the outer shell of the cover 1. The insert rod 606 slides through the corresponding opening of the plug 601 and is inserted into the insertion hole 107. The groove of the connecting seat 104 is not sealed to facilitate sliding connection with the T-shaped limiting piece 701. The positions of the plug tubes 6011 correspond one-to-one with the extrusion holes 401. Figure 2 As shown, the arrangement of the plug tube 6011 and the extrusion hole 401 is hexagonal, and the arrangement of the insertion rod 606 and the insertion hole 107 is also the same. The plug tube 6011 can be aligned with the extrusion hole 401 simply by inserting the insertion rod 606 and the insertion hole 107.
[0017] To achieve the purpose of flexibly fixing the cover 1, this application also includes a T-shaped limiting member 701 in the limiting component 7. The T-shaped limiting member 701 is fixedly connected to the side of the cover 5. A T-shaped push-pull rod 702 is fixedly connected to one side of the T-shaped limiting member 701. A pressing member 703 is slidably connected in the inner cavity of the T-shaped push-pull rod 702. A limiting ring 704 is fixedly connected in the inner cavity of the T-shaped push-pull rod 702. A limiting block 705 is fixedly connected to the side of the pressing member 703. The limiting block 705 fits against the limiting ring 704 to play a limiting role. A first spring 706 is sleeved on the side of the pressing member 703. The two ends of the first spring 706 are respectively fixedly connected to one end of the limiting block 705 and the bottom of the inner cavity of the T-shaped push-pull rod 702. Two trapezoidal locking blocks 707 slide through the inner cavity of the T-shaped limiting member 701. The two trapezoidal locking blocks 707 move in opposite directions. The two trapezoidal locking blocks 707 are in the T-shaped limiting member 701. The positioning member 701 is symmetrically arranged in the inner cavity. Several slots 105 are provided at the slots of the rotating plate 103 and the connecting seat 104. The trapezoidal locking block 707 is engaged with the slot 105 by sliding. The end of the pressing member 703 that extends into the T-shaped limiting member 701 is fixedly connected to the trapezoidal pressing block 708. The trapezoidal pressing block 708 presses the trapezoidal locking block 707 by sliding. The trapezoidal locking block 707 is fitted with a second spring 709. The elastic force generated by the first spring 706 is greater than the elastic force generated by the second spring 709. Without the intervention of external force, the trapezoidal pressing block 708 is pulled and pressed by the pressing member 703 to compress the trapezoidal locking block 707, so that the second spring 709 is compressed. The trapezoidal locking block 707 extends out from the inner cavity of the T-shaped limiting member 701. The two ends of the second spring 709 are fixedly connected to the inner wall of the T-shaped limiting member 701 and the extension plate of the trapezoidal locking block 707, respectively.
[0018] To achieve the purpose of sliding the cover 1 and the cleaning component 6, this application also includes a rotating shaft seat 101 fixedly connected to one side of the housing 1, a shaft rod 102 rotatably connected inside the shaft hole of the rotating shaft seat 101, a rotating plate 103 sleeved on the circumferential side of the shaft rod 102, the rotating shaft seat 101 and the rotating plate 103 being rotatably connected through the shaft rod 102, a connecting seat 104 fixedly connected to the side of the housing 1 opposite to the rotating shaft seat 101, one of the T-shaped limiting members 701 being slidably connected to the slot of the rotating plate 103, the rotating plate 103 being of suitable length and not interfering with the other T-shaped limiting member 701 being slidably connected to the slot of the connecting seat 104 through the movement of the cover 5.
[0019] In use, first rotate and open the machine cover 5, then pour the raw materials of the trace element additive into the machine housing 1 through the feed hopper 3. At the same time, start the motor 2. Since the output end of the motor 2 is fixedly connected to one end of the auger, the motor 2 will drive the auger to rotate after starting. During the rotation of the auger, the raw materials and adhesive inside will be fully mixed, and the mixed material will be pushed to the right and finally extruded through the extrusion hole 401 on the discharge plate 4. When the equipment needs to be stopped for cleaning after working for a period of time, first rotate the machine cover 5. Because a rotating shaft seat 101 is fixedly connected to one side of the machine housing 1, a shaft rod 102 is rotatably connected in the shaft hole of the rotating shaft seat 101. A rotating plate 103 is sleeved on the circumferential side of the shaft rod 102. The T-shaped limiting piece 701 is fixed on the circumferential side of the machine cover 5. The machine housing 1 is relative to the rotating shaft seat 1. On the other side of 01, a connecting seat 104 is fixedly connected. One T-shaped limiting member 701 is slidably connected to the slot of the rotating plate 103, and the other T-shaped limiting member 701 is slidably connected to the slot of the connecting seat 104 through the movement of the cover 5. Therefore, rotating the cover 5 can align the T-shaped limiting member 701 with the slot of the connecting seat 104. Also, because a T-shaped push-pull rod 702 is fixedly connected to one side of the T-shaped limiting member 701, and a pressing member 703 is slidably connected in the inner cavity of the T-shaped push-pull rod 702, a first spring 706 is sleeved on the periphery of the pressing member 703, and the two ends of the first spring 706 are respectively fixedly connected to one end of the limiting block and the bottom of the inner cavity of the T-shaped push-pull rod 702. Two symmetrically arranged ladders with opposite directions of movement slide through the inner cavity of the T-shaped limiting member 701. The trapezoidal locking block 707 is fixedly connected to one end of the pressing member 703 that extends into the T-shaped limiting member 701. The trapezoidal pressing block 708 slides and presses the trapezoidal locking block 707. The trapezoidal locking block 707 is fitted with a second spring 709. Several slots 105 are provided at the slots of the rotating plate 103 and the connecting seat 104. The trapezoidal locking block 707 slides and engages with the slots 105. Therefore, when both hands hold the T-shaped push-pull rod 702 and press the pressing member 703, the pressing member 703 moves and drives the trapezoidal pressing block 708 to move. The trapezoidal locking block 707 is no longer pressed by the trapezoidal pressing block 708. Under the elastic force of the second spring 709, the trapezoidal locking block 707 disengages from the slots 105. At this time, the machine cover 5 can be slid to make the connecting seat 104... The slotted part is slidably connected to the T-shaped limiting part 701. Then, the plug tube 6011 is aligned with the extrusion hole 401. By pulling the cover 5 back and forth, the raw material in the extrusion hole 401 can be cleaned. At this time, there is still raw material remaining on the discharge plate 4. Then, slide the cover 5 to the appropriate position, release the pressing part 703, the first spring 706 returns to its original position, the inclined surface of the trapezoidal extrusion block 708 presses the inclined surface of the trapezoidal locking block 707, the second spring 709 is compressed, and the trapezoidal locking block 707 engages with the corresponding locking groove 105. Since a square guide rod 604 is fixedly connected to one side of the mounting plate 603, and an L-shaped rocker arm 605 is fixedly connected to one side of the square guide rod 604, the square guide rod 604 slides through the side wall of the plug part 601. A bearing 106 is fixedly connected inside the outer shell of the cover 5.The inner ring of bearing 106 is fixedly connected to the circumferential side of the plug 601. Therefore, by holding the L-shaped rocker arm 605 and applying a pushing force, the mounting plate 603 is moved, causing the insertion rod 606 fixedly connected to one side of the mounting plate 603 to disengage from the insertion hole 107 on one side of the outer shell of the machine cover 5. The brush 602, which is slidably connected inside the plug tube 6011, extends out and comes into contact with the discharge plate 4. At this time, rotating the L-shaped rocker arm 605 causes the entire plug 601 to rotate, driving the brush 602 to clean out the waste. After cleaning the material plate 4, collect the raw materials. The materials inside the machine casing 1 can also be cleaned through the machine door. Rotate the L-shaped rocker arm 605 again to align the insertion rod 606 with the insertion hole 107. Pull the L-shaped rocker arm 605 to insert the insertion rod 606 into the insertion hole 107. Then, hold the T-shaped push-pull rod 702 and press the pressing part 703 to move the machine cover 5, causing the trapezoidal locking block 707 to engage with the corresponding slot 105, ensuring the machine cover 5 completely covers the discharge plate 4 to prevent debris from entering.
