Description

Technical Field

[0001] This utility model belongs to the field of material filling technology, and in particular relates to an adaptive material high-speed net weight module. Background Technology

[0002] In modern industrial production, material filling technology is an indispensable key process in packaging, manufacturing, and resource utilization. Its core objective is to achieve efficient and precise material distribution to meet product quality requirements and improve production efficiency. This device is an intelligent, modular piece of equipment in the field of material filling technology. Its core function is to automatically adapt to material characteristics and production needs during high-speed operation, and precisely control the net weight of the material to achieve quantitative filling.

[0003] For example, a packaging material filling mechanism proposed in announcement number CN222373217U includes: a material cup, an air intake speed control valve, a mounting base, and an opening and closing assembly. The air intake speed control valve is connected to the upper end of the material cup, the mounting base is connected to the middle of the material cup, and the opening and closing assembly is connected to the lower end of the material cup. The opening and closing assembly includes: a cylinder, a mounting frame, a drive block, a fixing block, an opening and closing nozzle, and a connecting shaft. Compared with traditional technology, this invention, by adding two opening and closing nozzles that cooperate with each other, can effectively prevent material spillage caused by the bag opening not being fully opened and pressing against the bag edge. It can also support the bag opening, improving the filling effect. Furthermore, the two opening and closing nozzles, when closed, can pre-store material, reducing filling time and improving work efficiency.

[0004] The above-mentioned patent has the following defects in use:

[0005] During the material filling process, the filling and closing of the material is achieved by the opening and closing of a pair of opening and closing nozzles driven by a cylinder. The specific material filling amount is controlled by the opening angle of the pair of opening and closing nozzles. For different material particles, errors can easily occur during a single filling process due to factors such as opening and closing speed and flowability, resulting in inaccurate material filling weight. Furthermore, the pair of opening and closing nozzles are designed with a petal structure, and when closed, they are sealed only by the mechanical rigid contact of the cylinder, lacking a corresponding sealing structure. Material particles (especially powders or small particles) are easy to get stuck in the gaps or the closure may not be tight due to asynchronous opening and closing, resulting in the risk of material leakage. This not only affects production efficiency but also poses a systemic challenge to product quality and process stability. Therefore, this utility model proposes an adaptive material high-speed net weight module. Utility Model Content

[0006] This invention provides an adaptive high-speed net weight module for materials. Through the coordinated operation of a dual-channel structure with large and small openings in the feeding device, it enables automatic segmented filling and feeding of materials. The large-opening adjustable feeding channel is controlled by a second motor driving a second hopper plate, quickly releasing 80% to 90% of the target material quantity. The small-opening adjustable feeding channel is controlled by a first motor driving a first hopper plate, accurately replenishing 10% to 20% of the remaining quantity. Combined with real-time calibration of the weighing bin, errors are eliminated, avoiding inaccurate material filling weight. The weighing bin uses triangularly distributed three-force sensors for redundant data verification, avoiding single-point overload and measurement deviation, improving overall accuracy. Furthermore, L-shaped sealing strips are provided at the tails of the first and second feeding plates to prevent leakage, and the sealing opening and closing is achieved through the linkage of the first and second cylinders. This module, through dual-channel coordinated control, redundant sensing structure, and sealing design, significantly improves filling efficiency, weighing accuracy, and process stability, making it suitable for the quantitative material distribution needs of intelligent manufacturing scenarios. In summary, it solves the problems in the background technology.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Specific Implementation

[0032] Please see Figures 1-6 As shown, the present invention provides an adaptive high-speed net weight module for materials, comprising:

[0033] The material feeding device 1 and the weighing bin 2 are located above the weighing bin 2.

[0034] The feeding device 1 includes a feeding device frame 101, a first motor 102, a second motor 103, a first hopper plate 104, and a second hopper plate 105. The first motor 102 is fixed on the feeding device frame 101, and its output end is connected to the first hopper plate 104. The first hopper plate 104 is located on the right side of the feeding device frame 101, and its bottom edge forms a small-opening adjustable feeding channel with the middle partition of the feeding device frame 101. The second motor 103 is fixed on the feeding device frame 101, and its output end is connected to the second hopper plate 105. The second hopper plate 105 is located on the left side of the feeding device frame 101, and its bottom edge forms a large-opening adjustable feeding channel with the middle partition of the feeding device frame 101.

[0035] In the specific implementation process, the feeding device 1 is responsible for controlling the release of materials, the weighing bin 2 is responsible for receiving materials and weighing them, and the second motor 103 drives the second hopper plate 105 to move, so that the materials are discharged at high speed through the large-opening adjustable feeding channel formed by the second hopper plate 105 and the middle partition of the feeding device frame 101. The second hopper plate 105 can change its relative position with the large-opening adjustable feeding channel through the drive of the second motor 103, thereby adjusting the large-opening adjustable feeding channel and controlling the material feeding rate or switching it on and off. When the material mass in the weighing bin 2 reaches 90% of the set threshold, the second motor 103 is controlled. The second hopper plate 105 is driven to close the large-opening adjustable feeding channel. At the same time, the first motor 102 drives the first hopper plate 104 to move, so that the material forms a small-opening adjustable feeding channel from the middle partition between the first hopper plate 104 and the feeding device frame 101 for micro-feeding. Similarly, the first hopper plate 104 can change its relative position with the small-opening adjustable feeding channel through the drive of the first motor 102, thereby adjusting the size of the small-opening adjustable feeding channel, controlling the material feeding rate or switching it on and off. Combined with the real-time calibration of the weighing bin 2, errors are eliminated, avoiding inaccurate material filling weight, and thus ensuring the efficiency and accuracy of the entire module.

[0036] The large-opening adjustable feeding channel is used to release the basic filling amount to the weighing bin 2, and the basic filling amount accounts for 80% to 90% of the target filling weight.

[0037] The large-aperture adjustable feeding channel is responsible for quickly releasing the basic filling amount into the weighing bin 2 in the first stage of the filling cycle, controlling the large-scale feeding of materials.

[0038] Among them, the small-opening adjustable feeding channel is used to finely release the remaining filling amount to the weighing bin 2, and the remaining filling amount accounts for 10% to 20% of the target filling weight.

[0039] The small-aperture adjustable feeding channel is responsible for finely releasing the remaining filling amount into weighing bin 2 in the second stage of the filling cycle, controlling the micro-feeding of materials.

[0040] The weighing chamber 2 includes a weighing chamber frame 201, a first force sensor 202, a second force sensor 203, a third force sensor 204, a first feeding plate 205, a second feeding plate 206, a first cylinder 207, a second cylinder 208, a first connecting rod 209, and a second connecting rod 2010. The first feeding plate 205 is located on the left side of the weighing chamber frame 201, and the second feeding plate 206 is located on the right side of the weighing chamber frame 201. The first cylinder 207... The head of the first cylinder 208 is connected to the first feed plate 205, and its tail is connected to the second feed plate 206; the head of the second cylinder 208 is connected to the first feed plate 205, and its tail is connected to the second feed plate 206; the head of the first connecting rod 209 is connected to the first feed plate 205, and its tail is connected to the second feed plate 206; the head of the second connecting rod 2010 is connected to the first feed plate 205, and its tail is connected to the second feed plate 206.

[0041] Material enters the weighing chamber 2 from the upper feeding device 1. At this time, the first cylinder 207, the second cylinder 208, the first connecting rod 209, and the second connecting rod 2010 work together to drive the first feeding plate 205 and the second feeding plate 206 to move closer to each other, completely sealing the outlet below the weighing chamber 2. Then, the total weight of the weighing chamber 2 and the material inside is transmitted to the first force sensor 202, the second force sensor 203, and the third force sensor 204 through the weighing chamber frame 201, so that they can be weighed. When the weighed material reaches the set threshold, the first cylinder 207 and the second cylinder 208 respectively drive the first connecting rod 209 and the second connecting rod 2010 to open the first feeding plate 205 and the second feeding plate 206, so as to achieve precise filling of the material quota.

[0042] Among them, the first force sensor 202, the second force sensor 203 and the third force sensor 204 are arranged in a triangle above the weighing bin frame 201.

[0043] The first force sensor 202, the second force sensor 203, and the third force sensor 204 are arranged in a triangle above the weighing bin frame 201 to avoid single-point overload and reduce measurement errors or sensor damage caused by local stress concentration. At the same time, the three force sensors verify each other's measurement data, which can eliminate abnormal values ​​caused by installation deviation, temperature drift, or noise of a single sensor and improve overall accuracy.

[0044] The first feeding plate 205 and the second feeding plate 206 are both provided with raised L-shaped sealing strips at their tails.

[0045] When the first discharge plate 205 and the second discharge plate 206 are closed, the L-shaped sealing strips at their tails will come into contact with or press against each other to form a sealing line, which effectively prevents the material from leaking out from the edge of the closed discharge port, avoids leakage of the material to be weighed during weighing, and further ensures the accuracy of the filling operation.

[0046] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.

[0048] The working principle of this utility model is as follows:

[0049] In use, material enters the feeding device 1 from the upper station of the module. The second motor 103 drives the second hopper plate 105 to move, causing the material to be fed at high speed through a large-opening adjustable feeding channel formed by the second hopper plate 105 and the middle partition of the feeding device frame 101. When the material mass in the weighing bin 2 reaches 90% of the set threshold, the second motor 103 is controlled to drive the second hopper plate 105 to close the large-opening adjustable feeding channel. At the same time, the first motor 102 drives the first hopper plate 104 to move, causing the material to be fed through a small-opening adjustable feeding channel formed by the first hopper plate 104 and the middle partition of the feeding device frame 101, for micro-feeding. The material enters from the upper feeding device 1... During the weighing process in weighing chamber 2, the first cylinder 207 and the second cylinder 208 drive the first connecting rod 209 and the second connecting rod 2010 to work together, causing the first feeding plate 205 and the second feeding plate 206 to move closer together, completely sealing the outlet below the weighing chamber 2. Then, the total weight of the weighing chamber 2 and the material inside is transmitted to the first force sensor 202, the second force sensor 203, and the third force sensor 204 through the weighing chamber frame 201, so that they can be weighed. When the weighed material reaches the set threshold, the first cylinder 207 and the second cylinder 208 drive the first connecting rod 209 and the second connecting rod 2010 respectively to open the first feeding plate 205 and the second feeding plate 206, so as to achieve precise filling of the material quota.
