Description

Technical Field

[0001] This utility model relates to the fields of pharmaceutical, food and chemical technology, and in particular to a granulator opening and pushing device. Background Technology

[0002] Granulators are indispensable production equipment for producing granulated products. However, after the granulator completes the mixing and granulation operation, a certain amount of material will adhere to the sealing cover of the granulator. In the traditional structure, during the opening process, the material adhering to the sealing cover will fall out of the pot, causing material waste and environmental pollution.

[0003] Currently, common methods include manual opening with spring assistance and automatic opening with cylinder lifting. However, after the sealing cover is opened, the edge of the sealing cover is outside the pellet mill. Although most of the material can fall into the pellet mill by gravity, a small portion of the material will fall outside the pellet mill along the edge of the sealing cover, resulting in material waste, environmental pollution, reduced yield, impact on the working environment, and health hazards for operators. Utility Model Content

[0004] The purpose of this invention is to provide a granulator cover-opening and pushing device that can push the lower end of the sealing cover horizontally to the top of the granulator during the opening process, preventing adhering materials on the sealing cover from falling outside the granulator. This avoids material waste, increases material yield, optimizes the working environment, and reduces health hazards for operators.

[0005] The pellet mill opening and pushing device includes a pellet mill and a sealing cover that matches the opening at the top of the pellet mill. The top of the sealing cover is connected to a lifting mechanism. The key feature is that it also has a pushing mechanism that works synchronously with the lifting mechanism. The pushing mechanism is connected to the edge of the sealing cover.

[0006] The lifting mechanism can lift the sealing cover to open it, while the pushing mechanism pushes the edge of the sealing cover flat above the granulator opening, causing the adhering material on the sealing cover to fall into the granulator, thereby avoiding material waste, improving material yield, optimizing the working environment, and reducing health hazards for workers during operation.

[0007] Furthermore, the lifting mechanism includes a lifting cylinder, which lifts the sealing cover via a lifting arm, and the lifting arm is rotatably mounted on the granulator body via a first fulcrum;

[0008] One end of the lifting arm is hinged to the piston rod of the lifting cylinder, and the other end of the lifting arm is hinged to the top of the sealing cover.

[0009] The piston rod of the lifting cylinder retracts downward, one end of the lifting arm sinks, and the other end of the lifting arm drives the sealing cover upward, thereby opening the sealing cover.

[0010] Furthermore, the lifting arm has a T-shaped structure, with the piston rod and sealing cover connected to both ends of its horizontal arm, and a pressure roller rotatably mounted on the free end of its vertical arm, which is connected to the internal pushing mechanism.

[0011] Furthermore, the internal pushing mechanism includes a Y-shaped push rod, in which the pressure roller is fitted inside the Y-shaped straight groove of the Y-shaped push rod, and one end of the long arm of the Y-shaped push rod is rotatably mounted on the body of the granulator via a second fulcrum;

[0012] The other end of the long arm is movably hinged to one end of the cover edge push rod, and the other end of the cover edge push rod is movably hinged to the cover edge of the sealing cover.

[0013] When the lifting cylinder pries the lifting arm to open the sealing cover, the pressure roller moves synchronously towards the sealing cover side, pushing one end of the long arm of the Y-shaped push rod to rotate towards the sealing cover side, pushing the cover edge push rod to move towards the sealing cover side, thereby pushing the cover edge of the sealing cover to above the granulator opening.

[0014] When the lifting cylinder pries the lifting arm to close the sealing cover, the pressure roller moves away from the sealing cover, pushing the long arm of the Y-shaped push rod to rotate away from the sealing cover, pulling the cover along the push rod back to the edge of the granulator opening.

[0015] Furthermore, a fixed bracket is welded to the side wall of the granulator, and the fixed bracket is provided with the first fulcrum and the second fulcrum.

[0016] Furthermore, the lower end of the cylinder body of the lifting cylinder is rotatably connected to the countertop, and its piston rod faces upward;

[0017] Alternatively, the cylinder body of the lifting cylinder may be rotatably connected to the body of the granulator.

[0018] Furthermore, the middle part of the horizontal arm of the lifting arm is fixedly hinged to the fixed bracket, one end of the horizontal arm of the lifting arm is movably hinged to the end of the piston rod, and the other end of the horizontal arm of the lifting arm is movably hinged to the top of the sealing cover.

[0019] Furthermore, the lifting mechanism includes a reducer connected to the motor, and the motor and reducer are fixed to the body of the granulator;

[0020] The output shaft of the reducer is connected to one end of the lifting arm, and the other end of the lifting arm lifts the sealing cover;

[0021] The lifting arm is also connected to the internal pushing mechanism, which is mounted on the body of the granulator via a second fulcrum.

[0022] Furthermore, a pressure roller is installed on the lifting arm, and the installation pressure roller is fitted into the Y-shaped straight groove of the Y-shaped push rod. The Y-shaped push rod is rotatably installed on the granulator body via the second fulcrum. The Y-shaped push rod is also movably hinged to the cover edge of the sealing cover via the cover edge push rod.

[0023] The output shaft of the reducer can also be connected to the Y-shaped push rod at the second fulcrum.

[0024] Furthermore, the lifting arm is provided with two parallel vertical arms, and the pressure roller is connected between the two vertical arms. The pressure roller passes through the Y-shaped straight groove, and bearings are respectively installed on the pressure rollers on both sides of the Y-shaped straight groove. The bearings are in rolling contact with the Y-shaped push rod.

[0025] Beneficial effects: This invention allows the sealing cap to be pushed horizontally above the granulator during the opening process, preventing any adhering material on the sealing cap from falling outside the granulator. This avoids material waste, increases material yield, optimizes the working environment, and reduces health hazards for workers during operation. Attached Figure Description
