Description

Technical Field

[0001] The present application relates to the field of pharmaceutical processing technology, and in particular to a hammer-type cover opening structure for a high-speed mixing granulator. Background Art

[0002] High-speed mixer granulator is a kind of equipment widely used in the pharmaceutical industry.

[0003] Existing high-speed mixing granulators generally include a tank body, a stirring rod, a motor and a sealing cover. A feed port is opened on the top of the tank body, the stirring rod is arranged inside the tank body, the motor is connected to the stirring rod and can drive the stirring rod to rotate to stir the material in the tank body, and the sealing cover is hinged on one side of the feed port and can seal the feed port.

[0004] However, since the sealing cover is usually heavy in order to ensure a sealing effect, the operator needs to spend a lot of effort to completely remove the sealing cover from the feed port.

[0005] In view of this, it is necessary to provide a high-speed mixing granulator with a heavy hammer type cover opening structure. Utility Model Content

[0006] In order to solve the problem that the sealing cover of the existing high-speed mixing granulator is heavy and inconvenient to open, the present application provides a heavy hammer type cover opening structure for the high-speed mixing granulator.

[0007] The present application provides a hammer-type lid opening structure for a high-speed mixing granulator, which adopts the following technical solution: it includes a lid body and a counterweight assembly, the lid body is hinged on the tank body and can block the feed port, the counterweight assembly is arranged on the side of the lid body away from the hinge axis with the hinge axis of the lid body as the center, and the counterweight assembly is connected to the lid body to form a whole and can balance the torque of the two ends of the whole relative to the hinge axis.

[0008] By adopting the above technical solution, since the counterweight assembly is connected to the cover body to form a whole, and the torques at both ends of the whole relative to the hinge axis are balanced with each other, the user only needs to apply a very small force to the cover body to drive the whole formed by the counterweight assembly and the cover body to rotate around the hinge axis, thereby significantly reducing the burden of opening the cover of the high-speed mixing granulator.

[0009] Specifically, the cover body includes a support rod, a connecting rod and a cover plate, the support rod is erected on the top of the tank body, and the middle part of the connecting rod is hinged to the top end of the support rod;

[0010] The counterweight assembly is connected to one end of the connecting rod, and the cover plate is connected to the other end of the connecting rod, and the cover plate can abut against and block the feed port.

[0011] By adopting the above technical solution, the configuration component can form a balance with the cover plate at both ends of the connecting rod.

[0012] Furthermore, the counterweight assembly includes a weight storage box and a sealing cover. The box body of the weight storage box is connected to the connecting rod. The interior of the weight storage box is suitable for holding counterweight blocks. The sealing cover is mounted on the box mouth of the weight storage box and can be screwed to the weight storage box by bolts.

[0013] By adopting the above technical solution, the user can adjust the weight of the configuration component by installing different numbers of counterweights in the weight storage box, so that the configuration component at one end of the connecting rod can be balanced with the cover plate of different weights at the other end of the connecting rod.

[0014] Furthermore, a sleeve rod is provided on the inner bottom wall of the weight storage box, a sleeve hole is opened in the middle of the counterweight block, and the counterweight block can be sleeved on the sleeve rod through the sleeve hole.

[0015] By adopting the above technical solution, the sleeve rod can limit the counterweight block in the weight storage box so that the counterweight block in the weight storage box will not shake when the cover plate rotates.

[0016] Specifically, it also includes a snap-on assembly, which includes a hook and a buckle. The hook is provided on the cover body, and the buckle is provided on the tank body. When the cover body seals the feed port, the cover body can be connected to the tank body via the buckle and the hook.

[0017] By adopting the above technical solution, the buckle can cooperate with the hook to fix the cover plate on the tank body.

[0018] Furthermore, the buckle includes a rotating rod and a clamping rod, one end of the rotating rod is hinged on the tank body, and the other end of the rotating rod is provided with a clamping groove adapted to the clamping hook;

[0019] A hinge shaft is provided on the groove wall of the card connection groove, and the middle part of the card rod is hinged on the hinge shaft. When the hook passes through the card connection groove, the bottom end of the card rod can abut against the hook part of the hook and make the line connecting the abutment point and the center of the hinge shaft perpendicular to the horizontal plane.

[0020] By adopting the above technical solution, after the bottom end of the clamping rod and the hook are abutted, and the line connecting the abutting point and the center of the hinge shaft is perpendicular to the horizontal plane, the center of the hinge shaft will limit the hook in the vertical direction, so that the end of the cover body with the hook cannot rotate upward, thereby fixing the cover plate on the tank body.

[0021] Furthermore, the cover body also includes a handle, which is arranged on a side of the cover plate away from the support rod.

[0022] By adopting the above technical solution, the user can lift the cover by holding the handle.

[0023] Furthermore, an observation window is provided on the cover plate, and a transparent member is provided in the observation window.

[0024] By adopting the above technical solution, the user can observe the material inside the tank through the observation window.

[0025] In summary, this application has the following beneficial technical effects:

[0026] The invention comprises a cover body and a counterweight assembly, wherein the cover body is hinged on the tank body and can block the feed port, and the counterweight assembly is arranged on a side of the cover body away from the hinge axis with the hinge axis of the cover body as the center, and the counterweight assembly is connected to the cover body to form a whole and can balance the torque of the two ends of the whole relative to the hinge axis. Since the counterweight assembly is connected to the cover body to form a whole, and the torque of the two ends of the whole relative to the hinge axis is balanced with each other, the user only needs to apply a very small force to the cover body to drive the whole formed by the connection of the counterweight assembly and the cover body to rotate around the hinge axis, thereby significantly reducing the burden of the opening operation of the high-speed mixing granulator.
