Description

TECHNICAL FIELD

[0001] The utility model relates to 3D printing technical field especially, it relates to a powder weighing structure convenient to operation. BACKGROUND

[0002] Additive manufacturing, particularly 3D printing technology, has been rapidly developed in recent years. However, the recycling and accurate proportioning of powder materials remain a key challenge in this field. Currently, many 3D printing processes, such as selective laser sintering (SLS) and multi-jet fusion (MJF), involve the reuse of powder materials. After each printing is completed, the unused powder needs to be mixed with new powder in a specific ratio to ensure the stability of subsequent printing quality. If the mixing ratio of new and old powder deviates, it will directly affect the mechanical properties, surface finish, and dimensional accuracy of the printed parts, and in severe cases, it may even cause printing failure. Therefore, accurately controlling the weight ratio of new and old powder is crucial, which is essential for achieving high-quality and high-efficiency 3D printing.

[0003] However, the existing powder weighing system has many shortcomings, limiting its effectiveness in practical applications. First, many weighing systems still rely on manual operation to handle and place the powder mixing barrels. This manual operation not only takes time and effort, but also easily causes alignment difficulties and human errors, increasing the labor intensity of the operators and reducing production efficiency.

[0004] Secondly, traditional weighing systems usually adopt a single-point support structure, which has poor stability. When the weight of the powder is large, the powder barrel is easily tilted towards the unsupported side, affecting the weighing accuracy. In addition, external vibrations or impacts can easily interfere with the single-point support weighing process, leading to inaccurate measurement data, and thus affecting the accuracy of the new and old powder proportioning.

[0005] Finally, the existing powder adding mechanism usually relies on manual control of valves to adjust the amount of powder added. This manual control method has slow response speed and is difficult to achieve fine flow control, which can easily cause large measurement errors, ultimately affecting the uniformity and consistency of powder mixing, and thus affecting the printing quality.

[0006] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the utility model is made based on this situation. INVENTION CONTENTS

[0019] In order to make the technical personnel of the prior art better understand the technical scheme of the utility model, the utility model will be further explained in detail below in combination with the drawings and concrete embodiment.

[0020] The utility model provides a powder weighing structure convenient to operate, and like Figure 1 And Figure 2 As shown in the figure. The structure aims to solve the problems of inconvenient operation, low precision and poor stability in the powder weighing and processing process in the prior art.

[0021] The core of the powder weighing structure lies in its innovative multi-point support and convenient pull-out design. Specifically, the structure includes a base 1, on which a plurality of weighing sensor modules 2 are evenly distributed. This multi-point support design can significantly improve the stability of the weighing platform compared to traditional single-point support, effectively avoiding tilting or measurement errors caused by uneven powder weight distribution. Above the weighing sensor modules 2 is provided with a weighing platform 3, which provides a stable bearing surface for the powder mixing barrel.

[0022] In this embodiment, the four weighing sensor modules 2 are evenly distributed between the base 1 and the weighing platform 3, achieving four-point support and measurement of the powder mixing barrel 7, further improving the stability and precision of the weighing.

[0023] In order to further improve the convenience of operation, the structure introduces a load-bearing platform 4 that can be pulled in and out. The load-bearing platform 4 is slidingly connected to the weighing platform 3 and achieves smooth pulling action through the guide rail type pulling structure 31. This guide rail type pulling structure 31, similar to the drawer slide rail, allows the operator to easily slide the powder mixing barrel 7 in or out of the weighing area without the need for laborious alignment and handling, greatly reducing the labor intensity of the operator and improving the operation efficiency. The outer end of the load-bearing platform 4 is also provided with a handle 41, further facilitating the operator's grip and pulling.

[0024] Above the load-bearing platform 4, a cover 5 is provided to prevent dust leakage and maintain a clean operating environment. The top of the cover 5 is provided with a powder adding device 6, which includes two powder adding pipes 61 and an electric butterfly valve 62. The electric butterfly valve 62 is used to accurately control the amount of powder added. Compared with traditional manual valves, the electric butterfly valve 62 has faster response speed and higher control precision, which can effectively avoid the mixing ratio error caused by inaccurate powder addition. By controlling the opening degree and time of the electric butterfly valve 62 through software, the amount of powder added can be accurately controlled, ensuring that the mixing ratio of new and old powder meets the preset requirements.

[0025] The weighing process of the powder weighing structure is as follows: first, the operator places the empty powder mixing barrel 7 on the bearing platform 4, and then slides the bearing platform 4 into the weighing area. A plurality of weighing sensor modules 2 simultaneously weigh the powder mixing barrel 7 at multiple points and transmit data to the control system. The control system calculates the required weight of the new powder according to the preset mixing ratio and controls the electric butterfly valve 62 to open, adding the new powder to the powder mixing barrel 7. After the powdering is completed, the system is weighed again to confirm that the total weight of the powder reaches the preset value. Finally, the operator slides the bearing platform 4 out and takes out the powder mixing barrel 7 containing the uniformly mixed powder for subsequent 3D printing process.

[0026] In addition, the powder weighing structure of the utility model has simple and efficient structure design, and can be assembled by only a few supporting plates, greatly simplifying the installation process and shortening the installation time.

[0027] In summary, the powder weighing structure of the utility model realizes high automation and precision of the powder weighing and processing process through the innovative design of multi-point weighing, pull-out type design and electric butterfly valve control. It has simple structure, easy installation and maintenance, can effectively reduce labor cost and maintenance cost, and has significant practical value and economic benefit.
