Description

Technical Field

[0001] The utility model relates to the technical field of gunpowder scales, in particular to a gunpowder scale material tube assembly. Background Art

[0002] In the field of precision batching and weighing, traditional manual weighing methods are no longer sufficient for handling high-precision and highly sensitive materials. This is particularly true for the preparation of chemical reagents, gunpowder, and trace pigments. Traditional methods lack efficiency and precision, and manual operation can introduce contamination and safety risks due to human contact. Consequently, the technology behind automated micro-quantity weighing has rapidly developed in recent years. High-precision automatic micro-weighing equipment has emerged. These devices typically utilize electronic sensors and computer control to achieve precise control and stable batching of trace materials, reducing errors caused by human intervention.

[0003] Chinese patent (CN210108490U) discloses an LCD touch screen integrated high-precision automatic micro-quantitative scale, including a barrel, a silo and a display screen. The barrel is installed above the silo, and the silo is also provided with calibration weights, a discharge pipe, a weighing platform and a display screen. Gunpowder is added through the barrel, and the gunpowder enters the weighing platform from the discharge pipe for weighing. In the prior art, the channel of the discharge pipe is relatively large, and the gunpowder flow rate is relatively fast, resulting in a faster flow rate of gunpowder when passing through the discharge pipe, which may affect the accuracy of weighing. Especially when the amount of ingredients is small and high-precision control is required, this problem of excessive flow rate can easily lead to over- or under-dosing, reducing the accuracy and stability of the system. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] In view of the following technical problems in the prior art: a gunpowder weighing tube assembly includes a discharge tube and a discharge plug, the discharge plug is connected to one end of the discharge tube by a thread, a feed slot is provided on the end of the discharge tube away from the discharge plug, and the channel diameter on the discharge plug is smaller than the channel diameter on the discharge tube.

[0006] As an optimal technical solution for a gunpowder weighing tube assembly, one end of the discharge tube is provided with an internal thread, and the discharge plug is provided with an external thread matching the internal thread.

[0007] As an optimal technical solution for a gunpowder weighing tube assembly, the feed slot is of an overall square structure, and the discharge slot is parallel to the outer wall of the discharge tube.

[0008] As an optimal technical solution for a gunpowder weighing tube assembly, one end of the discharge tube away from the discharge plug is provided with a chamfer.

[0009] The device of the present utility model has significant beneficial effects, which are specifically reflected in the following aspects. First, through the difference in channel diameter between the discharge plug and the discharge pipe, the device can effectively control the outflow rate of gunpowder, ensure that the gunpowder flows out in a stable and controllable manner, achieve accurate metering, avoid excessive or insufficient situations, and thus improve the accuracy of filling. Secondly, in terms of operational convenience, the end of the discharge pipe away from the discharge plug is designed with a chamfer, which allows the discharge pipe to be inserted into the gunpowder scale more smoothly. The chamfered design not only reduces the resistance during insertion and improves the smoothness of operation, but also facilitates operation in scenarios with frequent plugging and unplugging, thereby improving the convenience of using the device in conjunction with the gunpowder scale.

[0010] This device features a simple structure, employing conventional threaded connections and chamfered corners, making it easy to process and manufacture, reducing manufacturing costs and offering high economic efficiency. Furthermore, the chamfered corners not only facilitate insertion of the discharge tube but also reduce wear on the tube opening, ensuring the tube maintains its shape and function after repeated use, thereby extending the device's service life. The square feed slot, parallel to the outer wall of the discharge tube, optimizes the flow of gunpowder, ensuring smooth loading, reducing blockage, and further improving the efficiency and accuracy of gunpowder charging.

[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0017] In the following description, many specific details are set forth to facilitate 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 may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "one embodiment" or "embodiment" 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 various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0019] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing embodiments of the present invention, cross-sectional views of device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, three-dimensional dimensions, including length, width, and depth, should be included.

[0020] Please refer to Figures 1 to 3 As shown, the gunpowder weighing tube assembly includes a discharge tube 100 and a discharge plug 200. This assembly is designed to provide a reliable gunpowder dosing device, ensuring accurate metering and stable flow of gunpowder during the loading process. Specifically, the discharge plug 200 is threadedly connected to one end of the discharge tube 100. The other end of the discharge tube 100 is provided with a feed notch 102. The channel diameter of the discharge plug 200 is smaller than that of the discharge tube 100, thereby controlling the outflow rate of the gunpowder and effectively preventing problems such as excessive dumping and uneven flow.

[0021] In order to enhance the fixing effect between the discharge plug 200 and the discharge pipe 100, one end of the discharge pipe 100 is designed with an internal thread 101, which matches the external thread 201 on the discharge plug 200. In this way, the discharge plug 200 can be firmly fixed on the discharge pipe 100 to prevent it from loosening during the loading or movement of the gunpowder. In addition, this threaded connection also facilitates the assembly and disassembly of the components, improving the convenience of maintenance. When the discharge pipe 100 is directly installed on the gunpowder scale, the diameter of the discharge pipe 100 is large and the flow rate of the gunpowder is fast. The internal thread 101 of the discharge pipe 100 can effectively control the flow rate of the gunpowder, preventing problems such as excessive dumping and uneven flow.

[0022] As a structural improvement, the feed slot 102 adopts a square design. Compared with the traditional circular slot, the square structure can effectively improve the smoothness of the feed and reduce the risk of gunpowder blockage during the loading process. At the same time, the square feed slot 102 can be parallel to the outer wall of the feed tube, making the loading operation smoother and more efficient.

[0023] The design of chamfer 103 at the end of the discharge tube 100 away from the discharge plug 200 not only reduces wear on the tube mouth but also facilitates the smooth insertion of the discharge tube 100 into the gunpowder scale. The presence of chamfer 103 reduces resistance during insertion, allowing the discharge tube 100 to more smoothly align and enter the entrance position of the gunpowder scale, avoiding jamming or deformation of the tube mouth caused by collision or friction. This design greatly improves the convenience of assembly and the smoothness of operation, especially in environments with frequent insertion and removal or frequent operation, significantly improving efficiency and ensuring the stability and reliability of the connection between the discharge tube 100 and the gunpowder scale.

[0024] In summary, the design of this gunpowder weighing tube assembly fully considers factors such as metering, flow rate control, structural stability, and service life. Through reasonable structural design and precise tube diameter matching, this assembly provides precise discharge control during the gunpowder loading process and is suitable for various gunpowder metering and loading operations.

[0025] The embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
