Description

Technical Field

[0001] This utility model relates to the field of rotary tablet press technology, and in particular to a tablet press with a cleaning structure. Background Technology

[0002] A rotary tablet press is an automated tableting device used in the pharmaceutical, chemical, and food industries. Its core feature is that it continuously compresses powdered or granular raw materials into tablets through a rotating die system.

[0003] Tablet presses are widely used in the pharmaceutical and chemical industries. However, in actual use, drug powder easily accumulates on the surface of the rotary tableting assembly. Long-term accumulation not only affects the tableting quality and equipment operation stability, but may also cause equipment jamming or damage due to drug powder agglomeration. Traditional cleaning methods mainly rely on manual periodic shutdowns for cleaning, which is not only inefficient and increases the labor intensity of operators, but may also lead to production interruptions and affect overall production efficiency. In addition, manual cleaning is difficult to completely remove residual drug powder, especially in the hidden areas behind the rotary tableting assembly, which can easily form cleaning dead corners and further aggravate the risk of equipment contamination. In view of this, a tablet press with a cleaning structure is provided to overcome the above defects. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tablet press with a cleaning structure.

[0006] As a further description of the above technical solution: the end of the threaded rod away from the motor is rotatably connected to the lower middle of the hollow shell; the outer side of the moving block is slidably connected to the inner wall of the hollow shell; the outer side of the fixed rod is slidably connected to the middle of the front face of the hollow shell and the middle of the rear face of the machine body; the end of the connecting pipe away from the fan is fixedly connected to the left and right sides of the rear face of the cleaning plate; the left and right sides of the rear face of the machine body are slidably connected to the outer side of the connecting pipe. This can drive the cleaning plate at the rear of the machine body to slide up and down in a circular motion behind the rotating tableting assembly. With the help of the fan set behind the cleaning plate, the powder on the surface of the rotating tableting assembly is blown towards the front of the machine body through the air outlet on the front face of the cleaning plate. This can prevent the powder from remaining on the surface of the rotating tableting assembly for a long time, thereby affecting the normal operation of the rotating tableting assembly.

[0007] As a further description of the above technical solution: the longitudinal cross-sectional shape of the discharge trough is L-shaped, the cover plate is set at the front end of the discharge trough, and the cover plate is connected to the front end of the machine body by a hinge. The blown-away powder will be scattered in the discharge trough located inside the front of the machine body. The operator can open the cover plate to collect and process the powder in the discharge trough.

[0008] As a further description of the above technical solution: the middle of the front end face of the hollow shell and the middle of the rear end face of the machine body are both provided with a top-to-bottom sliding groove, and the width of the sliding groove matches the longitudinal section diameter of the fixed rod, so that the moving block inside the hollow shell can drive the cleaning plate at the rear of the machine body to move synchronously.

[0009] As a further description of the above technical solution: the motor can rotate forward and reverse, the moving block has a through hole in the middle from top to bottom, and the inner wall of the through hole is provided with an internal thread that matches the external thread on the outside of the threaded rod, so as to realize the purpose of moving the moving block up and down along the outside of the threaded rod by rotating the threaded rod.

[0010] As a further description of the above technical solution: the cleaning plate is hollow inside, and the front end face of the cleaning plate is provided with several air outlets, and the diameter of each air outlet is 1cm. The cross-sectional shape of the cleaning plate is semi-circular, and the cleaning plate is located behind the rotating tableting assembly. The powder on the surface of the rotating tableting assembly is blown to the front of the machine body through the air outlets on the front end face of the cleaning plate, which can prevent the powder from remaining on the surface of the rotating tableting assembly for a long time.

[0011] As a further description of the above technical solution: the guide rail is set from top to bottom, there are two sets of fans, and the fans are distributed at the left and right end faces of the hollow shell. The guide rail and the limiting slider can restrict the movement of the fans, so that when the cleaning plate moves up and down, the fans and the limiting slider are driven to slide up and down on the inside of the guide rail through the connecting pipe.

[0012] This utility model has the following beneficial effects:

[0013] This utility model designs a tablet press with a cleaning structure. Through the design and cooperation of a motor and a threaded rod, the device can drive a cleaning plate at the rear of the machine body to slide up and down in a circular motion behind the rotating tablet assembly. With the help of a fan located behind the cleaning plate, the powder on the surface of the rotating tablet assembly is blown towards the front of the machine body through the air outlet on the front face of the cleaning plate. This prevents the powder from remaining on the surface of the rotating tablet assembly for a long time, thus affecting the normal operation of the rotating tablet assembly. The blown-away powder will be scattered in the discharge trough located at the front of the machine body. The operator can open the cover plate to collect and process the powder in the discharge trough, which reduces the time and labor intensity required for the operator to clean the powder adhering to the surface of the rotating tablet assembly.
