Material mixing equipment is commonly used in manufacturing, processing, production, and research fields to ensure that materials are mixed uniformly and consistently.

[0003] Even after mixing, the existing materials still exhibit the following defects during discharge:

[0004] 1. The cylinder structure cannot accurately control the position of the discharge gate. In addition, the piston rod will retract after the air is cut off, resulting in poor sealing of the discharge port. This may lead to contamination of drugs or other mixtures inside the container, especially in high-sealing equipment.

[0005] 2. The position of the door panel cannot be fixed, which can easily lead to leakage when the material is blocked. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to precisely control the position of the discharge gate using a cylinder structure, the retraction of the piston rod after the cylinder is cut off, resulting in poor sealing of the discharge port, especially in highly sealed equipment. This may lead to contamination of the medicine or other mixtures inside the container, and the inability to fix the position of the gate, which in turn leads to leakage when the material is blocked. Therefore, this invention proposes a highly sealing discharge system.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-sealing discharge system includes a material cylinder with a discharge port on one side and an installation port on the other side. An installation frame is provided on the outer wall of the material cylinder at the installation port. A servo motor and a planetary reducer are mounted on the installation frame.

One end of the anti-rotation rod extends into the material cylinder and is provided with a pusher plate. A second wear-resistant sleeve is provided between the other end and the threaded push rod. A trapezoidal thread drive is provided between the second wear-resistant sleeve and the threaded push rod. Driven by the servo motor, the pusher plate moves along the discharge port direction to have a closed position (closing the discharge port) and an open position (separating from the discharge port).

[0009] Four vertical rods slide through the outer wall of the mounting bracket, and a braking component for braking the position of the second wear-resistant sleeve is provided on one side of each vertical rod.

[0010] The first wear-resistant sleeve has four placement slots arranged in a ring around its perimeter, and the placement slots are provided with fixing components for fixing the vertical rod.

[0015] In one possible design, the release assembly includes an operating rod that slides through the interior of the notch. One end of the operating rod is fixedly connected to a control ring, which is slidably fitted onto the outer wall of the mounting bracket. Multiple triangular blocks are fixedly connected to the outer wall of the control ring, and these triangular blocks cooperate with a limiting plate.

[0016] In one possible design, the sealing assembly includes a rotating ring fixedly connected to one side of a pusher plate. A second ring is rotatably connected to one side of the rotating ring, and multiple gear teeth are fixedly connected to the inner wall of the second ring. A first circular groove is formed on one side of the pusher plate, and a third circular groove is formed on the other side of the pusher plate. A second circular groove is formed inside the pusher plate, connecting the third circular groove and the first circular groove. A threaded cylinder rotatably passes through the inner wall of the first circular groove, and a gear that meshes with the gear teeth is fixedly fitted onto the outer wall of the threaded cylinder. A pressing block is slidably connected inside the third circular groove. A screw is fixedly connected to one side of the pressing block. A second spring is fixedly connected between one side of the pressing block and the inner wall of one side of the third circular groove. The second spring is sleeved on the screw. Multiple arc-shaped pieces are fixedly connected to one side of the second ring. A first ring is slidably sleeved on the outer wall of the rotating ring. Multiple rectangular pieces are fixedly connected to one side of the first ring. The arc-shaped pieces and the rectangular pieces are used in conjunction. A second rubber pad and a first rubber pad are fixedly connected to one side of the first ring. The second rubber pad is located between the pusher gate plate and the first ring. The first rubber pad is located between the first ring and the material cylinder.

[0017] In one possible design, the mounting port is provided with a sealing ring, the outer circular surface of the sealing ring is provided with an annular groove, the edge of the mounting port is embedded in the annular groove, one side of the sealing ring abuts against the first wear-resistant sleeve, and the other side protrudes into the material cylinder, the mounting bracket is covered with an outer cover, the outer cover is detachably connected to one side of the material cylinder, and the servo motor and planetary reducer are both located inside the outer cover.

[0018] In one possible design, the discharge port is provided with a continuous first oblique sealing surface and a first flat sealing surface along the discharge direction. The cross-sectional area of ​​the first oblique sealing surface gradually increases towards the material cylinder. The push gate plate is provided with a second oblique sealing surface adapted to the first oblique sealing surface and a second flat sealing surface adapted to the first flat sealing surface. The second oblique sealing surface is provided with a sealing ring groove, and a sealing ring is provided in the sealing ring groove.

[0019] In one possible design, the outer contour of the anti-rotation rod cross-section is polygonal. A connecting seat is provided at one end of the anti-rotation rod near the pusher plate, and the connecting seat is fixed to the pusher plate. A connecting rod portion is provided at one end of the anti-rotation rod near the pusher plate. A connecting cylinder is provided on the pusher plate. The connecting rod portion is threadedly engaged with the connecting cylinder. A locking nut is provided on the connecting rod portion, and the locking nut is located between the connecting cylinder and the connecting seat.

[0020] In one possible design, the pusher panel has an arc-shaped recess on the side away from the anti-rotation rod, and the bottom of the arc-shaped recess extends a guide arc-shaped surface in the direction away from the anti-rotation rod.

[0021] In this application, during use, the servo motor is started, and the output shaft of the servo motor drives the threaded push rod. The threaded push rod drives the anti-rotation rod to move laterally, and the anti-rotation rod drives the pusher gate plate to move laterally. The pusher gate plate blocks the discharge port. When the second wear-resistant sleeve moves to the farthest point, the second wear-resistant sleeve pushes multiple push rods into the interior of the round hole. The round hole drives the sliding plate to move laterally and squeezes the first spring. At this time, the sliding plate drives the locking rod to move laterally, and the locking rod moves out from the interior of the vertical rod.

[0022] At this time, the braking state of the vertical rod is released. Under the tension of the tension spring, the limiting plate moves vertically downward. The limiting plate drives the vertical rod to move vertically downward, the vertical rod drives the connecting plate to move vertically downward, and the connecting plate drives the abutting plate to move vertically downward. At this time, the abutting plate abuts against one side of the second wear-resistant sleeve to prevent the second wear-resistant sleeve from shaking. At the same time, the vertical rod enters the interior of the placement groove to improve stability.

[0023] Furthermore, when the pusher door moves to its furthest point, the pressing block is abutted, enters the interior of the third circular groove and squeezes the second spring. The pressing block drives the screw to move from the interior of the second circular groove to the interior of the threaded cylinder, and drives the threaded cylinder to rotate. The threaded cylinder drives the gear to rotate, the gear drives the gear teeth to rotate, the gear teeth drive the second ring to rotate, and the second ring drives multiple arc-shaped pieces to move laterally. The arc-shaped pieces abut against multiple rectangular pieces, which in turn pushes the first ring to move laterally. The first ring squeezes the second rubber pad and presses the first rubber pad against the inner wall of the material cylinder, improving the sealing performance of the device.

[0024] When it is necessary to release the device brake, the operating lever can be moved laterally. The operating lever drives the control ring to move laterally, the control ring drives the triangular block to move laterally, the triangular block drives multiple limit plates to move away from each other, the multiple limit plates drive the vertical rod to move away from each other, the vertical rod is no longer engaged with the placement slot, and at the same time the clamping plate no longer abuts against one side of the second wear-resistant sleeve, which can cause the threaded push rod to rotate in the opposite direction, driving the push gate plate to retract.

[0025] In this invention, the high-sealing discharge system can achieve the effect of braking the position of the second wear-resistant sleeve through a braking component;

[0026] In this invention, the high-sealing discharge system can improve the sealing performance of the device through the sealing components.

[0027] In this invention, driven by a servo motor, a planetary reducer rotates the threaded push rod, which in turn drives the anti-rotation rod to move the pusher plate horizontally and precisely, thus opening and closing the material cylinder outlet. Wear-resistant materials are used in the relative movement positions to extend the service life of the mechanism. Furthermore, the conversion of rotational motion into linear motion using a trapezoidal thread transmission makes the pusher plate movement more stable. A fixing component secures the first wear-resistant sleeve, improving the device's sealing performance. The contact between the first and second rubber pads and the material cylinder further enhances the device's sealing performance, making it convenient to use. Attached Figure Description
