The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0020] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] The utility model provides a raw material crushing and screening device, such as Figure 1-4 As shown, the raw material crushing and screening device includes: a processing box 1 for crushing and processing Captopril tablet raw materials, wherein the processing box 1 is provided with a crushing chamber 2, a recovery chamber 3 and a screening chamber; a first crushing roller 4 meshingly and rotatably installed in the crushing chamber 2, wherein the first crushing roller 4 is used to crush the Captopril tablet raw materials; a second crushing roller 5 meshingly and rotatably installed in the recovery chamber 3, wherein the second crushing roller 5 is used to crush the screened Captopril tablet raw materials; a driving motor 6 fixed to the outside of the crushing chamber 2 and the outside of the recovery chamber 3 for driving the first crushing roller 4 and the second crushing roller 5, respectively, wherein the driving motor 6 is fixedly connected to the shaft corresponding to the first crushing roller 4 and the second crushing roller 5; an inclined screen plate 7 arranged in the screening chamber for screening raw materials, wherein one end of the screen plate 7 extends into the recovery chamber 3; and an assembly vibration mechanism arranged in the screening chamber for assembling the screen plate 7 to regulate its fluctuation vibration.
[0022] It should be noted that, however, although the traditional raw material crushing and screening devices can perform basic crushing and screening functions in the pharmaceutical, chemical, food and other industries, they are unable to further effectively process the screened raw materials; this deficiency is mainly manifested in the following aspects: First, the traditional crushing and screening devices often only focus on the initial crushing and particle size classification of the raw materials, but lack in-depth processing of the raw materials after screening. The screened raw materials may contain particles, impurities or undesirable components that do not meet the particle size requirements. These untreated raw materials are directly used in subsequent production, which will seriously affect the uniformity and stability of the product. Especially in the field of pharmaceutical production, the purity and particle size distribution of raw materials are crucial to product quality. The shortcomings of traditional devices often lead to substandard drug quality and even safety hazards; secondly, low raw material utilization is another major problem of traditional devices. Due to the lack of fine processing of the raw materials after screening, the useful components in the raw materials are often not fully utilized, resulting in waste of resources; at the same time, the presence of impurities and undesirable components will also increase the difficulty and cost of subsequent processing, further reducing the utilization rate of raw materials; in addition, traditional devices also have bottlenecks in production efficiency. Due to the imperfect processing flow, the device often needs to be adjusted and optimized repeatedly, resulting in longer production time and lower efficiency; this not only increases production costs, but also limits the company's production capacity and market competitiveness; in summary, the traditional raw material crushing and screening device has obvious deficiencies in further effectively processing the screened raw materials, which leads to low raw material utilization, unstable product quality and difficulty in improving production efficiency.
[0023] In this embodiment, the device includes a processing box 1, which is internally divided into a crushing chamber 2, a recovery chamber 3 and a screening chamber.

This design allows the rotation speed and power of the crushing roller to be precisely controlled, thereby achieving fine processing of the raw materials; an inclined screen plate 7 is provided in the screening chamber, one end of which extends into the recovery chamber 3, so as to facilitate the introduction of the screened raw materials into the recovery chamber 3 for re-crushing; at the same time, the assembled vibration mechanism can regulate the ups and downs of the screen plate 7 to improve the screening efficiency and accuracy; this design effectively separates raw materials of different particle sizes and ensures the quality of raw materials for subsequent production; through the design of double crushing rollers and fine screening in the screening chamber, the useful components in the raw materials are fully utilized, reducing resource waste; the raw materials that have been deeply processed have higher purity and particle size uniformity, thereby improving the quality and stability of the product and reducing safety hazards; the multi-chamber design, precisely controlled crushing rollers and efficient screening mechanism make the entire processing flow smoother, reduce production time and cost, and improve overall production efficiency.
