Description

Technical Field

[0001] The utility model belongs to the technical field related to medicine production, and particularly relates to a grinding device for active raw materials of ointments. Background Art

[0002] Ointment refers to a semi-solid topical preparation with a certain consistency made by uniformly mixing a drug with a suitable matrix. Common matrices are divided into oily, water-soluble and emulsion matrices. Due to the different dispersion states of the drug in the matrix, it is divided into solution-type ointments and suspension-type ointments. Solution-type ointments are ointments made by dissolving or co-melting the drug in a matrix or matrix components, and suspension-type ointments are ointments made by uniformly dispersing fine drug powder in the matrix. For example, ichthyol ointment or erythromycin ointment must contain some solid substances in their raw materials. These solid substances must be ground into particles of very small size when making ointments, and then undergo subsequent processing. However, the following disadvantages still exist in the actual grinding operation:

[0003] 1. First, in the grinding process of drug raw materials, when the raw material particles are ground to be fine enough, dust and other effects will inevitably be generated. First, it affects the surrounding environment, and second, it causes a waste of raw materials;

[0004] 2. Secondly, grinding is usually done with rough grinding discs that are in contact with each other. Most of these grinding structures have rough grains like frosted sand. During the grinding process, some raw materials may get stuck in the grains of the grinding surface, causing waste or affecting the grinding effect, and increasing the grinding time.

[0005] 3. After the raw materials of the ointment are ground, there will inevitably be some residues in the grinding parts and the corresponding containers. If different raw materials need to be ground subsequently, they need to be cleaned before use. However, many parts cannot be cleaned in water. If it is an integrated structure, it will easily increase the difficulty of cleaning. Utility Model Content

[0006] The purpose of the utility model is to provide an ointment active raw material grinding device, which solves the problems of powder dust dispersion during grinding, residual raw materials in the texture of the grinding parts during grinding, reduced grinding effect and increased grinding time, and inconvenient cleaning after grinding by arranging a grinding jar, a jar cover, a base, a vibration motor, a grinding ball, a cleaning brush, and a cylinder.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model discloses an ointment active raw material grinding device, comprising a base, a grinding jar, a jar cover, a cylinder, grinding balls and a cleaning brush, wherein a vibration motor is fixed on the upper end of the base, and a grinding jar is movably arranged on the base on one side of the vibration motor, the upper end of the grinding jar is threadedly screwed with the jar cover, the upper end of the jar cover is rotatably connected with a rotating disk, the upper end of the rotating disk is fixed with a cylinder, and relatively distributed grinding balls and a cleaning brush are arranged in the inner cavity of the grinding jar below the rotating disk, and a circular grinding groove is arranged in the lower area of ​​the inner cavity of the grinding jar, and the outer spherical surface of the grinding ball contacts the grinding groove.

[0009] Furthermore, an inverted U-shaped bracket is fixed to the upper end of the tank cover outside the rotating disk, and a grinding motor is fixed to the top of the bracket. The output shaft of the grinding motor passes downward through the horizontal part of the bracket and is fixed to the center of the upper end surface of the rotating disk.

[0010] Furthermore, a main rod is fixed on the outer spherical surface of the grinding ball at a position closest to the central axis of the grinding jar, and the top end of the main rod is screwed into the bottom of the rotating disk through a thread.

[0011] Furthermore, an L-shaped support rod is fixed at the highest point of the outer spherical surface of the grinding ball, and the bottom end of the vertical part of the support rod is fixed to the grinding ball, and the horizontal part of the support rod is fixed to the outer periphery of the main rod.

[0012] Furthermore, the bristle portion of the cleaning brush contacts the inner wall of the grinding jar, and an inclined rod is fixed to a side of the cleaning brush away from the inner wall of the grinding jar.

[0013] Furthermore, the piston rod at the telescopic end of the cylinder passes downward through the rotating disk and is fixed with a threaded barrel, and the upper end of the inclined rod is threadedly connected in the threaded barrel.

[0014] Furthermore, the cross section of the rotating disk is I-shaped, and the upper part of the rotating disk protrudes from the upper end surface of the tank cover, and the lower part of the rotating disk protrudes from the inner top surface of the tank cover.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model solves the problem of powder dust emission during grinding by providing a grinding jar and a jar cover; the raw materials to be ground are placed in the grinding jar, and then the jar cover is rotated to close the upper end of the grinding jar. The entire grinding process is carried out in the inner cavity of the grinding jar, and there is no dust leakage or dust generation as a whole, thereby realizing closed grinding, saving costs, and not causing environmental impact.

[0017] 2. The utility model solves the problem that raw materials will remain in the patterns of the grinding parts during grinding, and cannot be mixed with the remaining raw materials in time, which reduces the grinding effect and increases the grinding time by arranging a base, a vibration motor, a grinding ball, a cleaning brush and a cylinder. During grinding, the grinding motor works to drive the rotating disk to rotate, thereby rotating the grinding ball connected to its bottom end, and the grinding ball moves along the grinding groove in the grinding jar. The surface of the grinding groove and the outer spherical surface of the grinding ball are both grinding surfaces. When the two grind the raw materials, part of the raw materials may be stuck in the gap. At this time, the cleaning brush following the grinding ball, under the up and down telescopic drive of the cylinder, brushes the surface of the grinding groove, brushes the raw materials stuck in the gap down, and mixes them with the remaining raw materials. At the same time, the vibration motor works to vibrate the grinding jar to make the raw materials in the grinding groove fall down, and can also concentrate the raw materials in the grinding jar at the inner bottom center of the grinding groove, so that it can be ground evenly and concentratedly.

[0018] 3. The utility model solves the problem of inconvenient cleaning after grinding by arranging grinding balls, cleaning brushes, grinding jars and jar covers; the grinding balls are threadedly connected to the rotating disk through a main rod, and a support rod is added to enhance the structural stability; the cleaning brush is also threadedly connected to the threaded barrel at the telescopic end of the cylinder through an inclined rod; both the grinding balls and the cleaning brush are detachable, realizing a split structural design, which is more convenient for cleaning.
