Description

Technical Field

[0001] This utility model relates to the field of tablet manufacturing technology, specifically a cooling tablet press turntable. Background Technology

[0002] The rotary table is the core load-bearing component of a tablet compressor. It is widely used in mass production of various tablets (such as plain tablets, coated tablets, and sustained-release tablets), and is suitable for laboratory small-scale, pilot-scale, and industrial-scale large-volume tablet compressing needs. It is a key hub connecting material filling, compression molding, and tablet output.

[0003] However, the above-mentioned device still has the following problems during implementation: Existing technology causes the rotary tablet press to generate heat during the tablet pressing process, resulting in high temperatures for the turntable, mold, and extruded tablets. However, for certain special tablets, the temperature must not exceed a certain limit, otherwise the tablet properties will change. Therefore, a cooling tablet press turntable is proposed to solve the above problems. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a cooling tablet press turntable, which has the advantage of cooling. This solves the problem that the rotary tablet press generates heat during the tablet pressing process, resulting in high temperatures of the turntable, mold, and pressed tablets. However, for some special tablets, the temperature must not exceed a certain limit, otherwise the tablet characteristics will change.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cooling tablet press turntable, comprising a main shaft, two coolant pipes and a turntable, wherein the coolant pipes are opened at the top and bottom of the main shaft, and the turntable is sleeved on the surface of the main shaft, and both the top and bottom are connected to the main shaft through bearings; The inner cavity of the coolant pipeline is connected to a rotary joint via a thread; A cooling assembly is disposed at the top and bottom of the turntable.

[0006] As a preferred embodiment of the present invention, the cooling assembly includes a cooling cavity, which is located at the top and bottom of the turntable, and a sealing cover is fixedly connected to the inner cavity of the cooling cavity by bolts.

[0007] As a preferred embodiment of this invention, the inner cavity of the cooling chamber is provided with a sealed pipe, and the left side of the sealed pipe penetrates the cooling chamber and is connected to the coolant pipeline.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model solves the problem that the rotary tablet press generates heat during the tablet pressing process, resulting in high temperatures of the turntable, mold, and pressed tablets. However, for some special tablets, the temperature must not exceed a certain limit, otherwise the tablet properties will change. This invention achieves the effect of cooling.

[0009] 2. This utility model, by setting up cooling components and sealing pipes, addresses the issue that the turntable and die generate high temperatures through continuous friction under high pressure. Prolonged high temperatures can accelerate the wear, deformation, and even jamming of metal parts. Cooling can reduce the thermal stress of the parts, extend the service life of vulnerable parts such as the turntable and die, and reduce the frequency of downtime maintenance. The sealing cover is fixed with bolts to ensure the sealing of the cooling cavity, so that the cooling water will not leak. Attached Figure Description

[0012] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0013] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0014] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0015] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0016] Example 1 Reference Figure 1-4 The first embodiment of this utility model provides a cooling tablet press turntable, including a main shaft 1, two coolant pipes 2 and a turntable 3. The coolant pipes 2 are opened at the top and bottom of the main shaft 1, and the turntable 3 is sleeved on the surface of the main shaft 1, and the top and bottom are connected to the main shaft 1 through bearings. The inner cavity of the coolant pipe 2 is connected to a rotary joint 4 via a thread; Cooling assembly 5 is located at the top and bottom of turntable 3.

[0017] Specifically, when the turntable 3 is producing tablets, the cooling component can cool the turntable 3. Cooling can also maintain the stable shape of the material and ensure the consistency of the hardness, thickness and appearance of each tablet.

[0018] Furthermore, this device is part of a tablet press and is used during operation; The turntable 3 has three different holes: the lower hole houses the lower punch, the middle hole houses the middle mold, and the upper hole houses the lower punch. When the upper and lower punches press the tablets in the middle mold, the temperature of the turntable 3 gradually increases. The cooling water pipe is then connected to the top rotary joint 4. The cooling water then flows through the rotary joint 4, coolant pipe 2, and sealed pipe 6 into the upper cooling chamber 51. The upper cooling chamber 51 then flows through the bottom hole into the lower cooling chamber 51. After the cooling water cools the chamber, it flows through the lower sealed pipe 6 into the bottom coolant pipe 2 for discharge.

[0019] Example 2 The second embodiment of this utility model provides a cooling tablet press turntable. The cooling assembly 5 includes a cooling cavity 51, which is located at the top and bottom of the turntable 3. A sealing cover plate 52 is fixedly connected to the inner cavity of the cooling cavity 51 by bolts. A sealing pipe 6 is provided in the inner cavity of the cooling cavity 51. The left side of the sealing pipe 6 passes through the cooling cavity 51 and is connected to the coolant pipe 2.

[0020] Specifically, by setting up cooling components 5 and sealing pipes 6, the turntable 3 and the die continuously rub against each other under high pressure to generate high temperatures. Long-term high temperatures will accelerate the wear, deformation, or even jamming of metal parts. Cooling can reduce the thermal stress of the parts, extend the service life of vulnerable parts such as the turntable 3 and the die, and reduce the frequency of downtime maintenance. The sealing cover plate 52 is fixed by bolts, which can ensure the sealing of the cooling cavity 51, so that the cooling water will not leak.

[0021] In summary, the cooling effect is achieved through the cooperation of the spindle 1, coolant pipeline 2, turntable 3, rotary joint 4, cooling assembly 5, cooling chamber 51, sealing cover plate 52 and sealing pipe 6.

[0022] The spindle 1, coolant pipeline 2, turntable 3, rotary joint 4, cooling cavity 51, sealing cover 52, and sealing pipe 6 used in this application can be additionally equipped with protective measures of common knowledge in this technical field under different usage environments. These measures include, but are not limited to, spraying a high-hardness coating, an anti-stick coating, or changing the hardness of the heat treatment. These are common technical means used by those skilled in the art.
