Description

Technical Field

[0001] This utility model relates to the field of photovoltaic silver paste production technology, specifically to a quantitative feeding photovoltaic silver paste production batching equipment. Background Technology

[0002] In the production process of photovoltaic silver paste, the batching process is crucial. The amount of each raw material added must be precisely controlled to ensure the performance and quality of the silver paste. In the production process of photovoltaic silver paste, different materials need to be continuously added to the batching tank. When there are many types of materials to be added, a single feeding device will increase the working cycle and it is difficult to add materials in batches and adjust the feeding rate.

[0003] Existing photovoltaic silver paste production batching equipment lacks an effective batch feeding mechanism when dealing with multiple materials, resulting in a chaotic material addition sequence, affecting the final quality of the silver paste, and making it difficult to accurately control the proportions of various raw materials. Consequently, the performance of the silver paste is unstable and cannot meet the high quality requirements of photovoltaic cell production. Utility Model Content

[0004] To address this issue, this invention provides a quantitative feeding photovoltaic silver paste production batching device. This device solves the problem that photovoltaic silver paste production batching devices lack an effective batch feeding mechanism when dealing with multiple materials, leading to a chaotic material addition sequence, affecting the final quality of the silver paste, and making it difficult to accurately control the proportions of various raw materials. Consequently, the performance of the silver paste becomes unstable and fails to meet the high quality requirements of photovoltaic cell production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic silver paste production batching equipment with quantitative feeding, comprising a mixing tank, wherein the top of the mixing tank is provided with two quantitative feeding mechanisms;

[0006] The quantitative feeding mechanism includes a connecting shell, which is fixedly mounted on the top of the mixing tank. A third motor is fixedly mounted on one side of the connecting shell, and a transmission rod is fixedly connected to the output end of the third motor. The transmission rod passes through the side wall of the connecting shell and is connected to the side wall of the connecting shell via a bearing. A side shell is fixedly connected to one end of the transmission rod. Two sleeves are fixedly mounted on one side of the side shell, and a connecting frame is fixedly mounted on one side of the two sleeves. A rotating shaft is fixedly connected to one side of the connecting frame, and one end of the rotating shaft is connected to the side wall of the connecting shell via a bearing. A fourth motor is fixedly mounted on one side of the side shell, and a lead screw is fixedly connected to the output end of the fourth motor. The lead screw is connected to the inner wall of the side shell via a bearing. A connecting plate is threaded onto the outside of the lead screw. A vertical plate is fixedly mounted on one side of the connecting plate, and a weighing scale is fixedly mounted on both sides of the vertical plate. The weighing scale is located inside the sleeve.

[0007] Preferably, the top of the connecting shell is provided with two feeding components. Each feeding component includes a feeding pipe, which is fixedly located on the top of the connecting shell. A conveying pipe is fixedly located on the top of the feeding pipe. A second motor is fixedly located on one side of the conveying pipe. A spiral conveying rod is fixedly connected to the output end of the second motor. The spiral conveying rod is located inside the conveying pipe. A mixing tank is fixedly located on the top of the conveying pipe.

[0008] Preferably, a feeding pipe is fixedly provided on the top of the mixing tank.

[0009] Preferably, a plurality of second support columns are fixedly provided at the bottom of the mixing tank, and the second support columns are fixedly connected to the top of the mixing tank.

[0010] Preferably, a feed pipe is fixedly provided at the top of the mixing tank.

[0011] Preferably, an air pump is fixedly installed on the top of the mixing tank, and the output end of the air pump is connected to a nozzle that extends into the interior of the mixing tank.

[0012] Preferably, a first motor is fixedly installed on the top of the mixing tank, and a drive shaft is fixedly connected to the output end of the first motor.

[0013] Preferably, a feed pipe is fixedly provided on one side of the mixing tank.

[0014] Preferably, the bottom of the mixing tank is fixedly provided with a plurality of first support columns.

[0015] The present invention has the following advantages:

[0016] 1. By setting up two quantitative feeding mechanisms, each with a unique structural design, different materials can be fed in batches. When dealing with multiple materials, different materials can be added to the mixing tank in a preset order, avoiding the problem of chaotic material addition order. This effectively improves the efficiency and accuracy of the batching process and provides a guarantee for the production of high-quality photovoltaic silver paste.

[0017] 2. In the quantitative feeding mechanism, the rotation speed of the screw conveyor is controlled by the second motor, which can accurately control the conveying amount of different materials from the batching tank to the connecting shell, thus realizing the precise adjustment of the feeding rate. At the same time, combined with the precise measurement of the material weight by the weighing scale, it further ensures that the proportion of various raw materials can be accurately controlled, effectively solving the problems of difficult adjustment of feeding rate and inaccurate control of raw material proportion in existing equipment, thereby ensuring the stability of photovoltaic silver paste performance.

[0018] 3. During the quantitative feeding process, the side shell is rotated by the third motor, causing the sleeve containing the ingredients to rotate to the bottom, and the ingredients fall directly into the mixing tank. Then, the fourth motor is started to control the lead screw to rotate, driving the weighing scale to move down to the opening of the sleeve. Then, the air pump is started to deliver air through the nozzle to blow away the ingredients on the surface of the weighing scale and clean it. This design greatly reduces the residue of materials during the feeding process, avoids the waste of raw materials, and also prevents the residual materials from affecting the quality of subsequent batches of silver paste production.
