[0002] In the field of material packaging technology, especially for packaging granular materials, the efficient and precise execution of key operations such as bag clamping, detection, and dispensing has always been a key focus of the industry. Currently, existing dispensing pipes face several technical challenges in practical applications. Specifically, they suffer from poor bag clamping stability, making it difficult to ensure the bag is securely fixed during dispensing; insufficient accuracy in detecting the placement of plastic bags, making it impossible to reliably determine whether the bag has been correctly installed; and poor coordination in dispensing control, hindering smooth and precise material delivery. These technical deficiencies directly lead to low packaging efficiency and significantly increase the risk of material leakage. Therefore, a new type of bag clamping, detection, and dispensing pipe is urgently needed to effectively solve these technical problems. Summary of the Invention

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided through embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concepts of this application.

[0025] Referring to Figures 1-3, the structure of the bag clamping detection and discharge pipe of this application is shown. The structure mainly consists of a connecting bracket 1, a clamping cylinder assembly 2, and a discharge pipe 3.

[0026] First, let's introduce the connecting bracket part. The connecting bracket 1 includes a first connecting bracket 11 and a second connecting bracket 12. One side of the feeding pipe 3 is fixedly connected to the first connecting bracket 11, and the other side is fixedly connected to the second connecting bracket 12.

[0027] Next, we will introduce the clamping cylinder assembly 2, which consists of clamping cylinders and clamping components. The clamping cylinders include a first clamping cylinder 21 and a second clamping cylinder 22, while the clamping components include a first clamping component 23 and a second clamping component 24. The first clamping cylinder 21 is bolted to the first connecting bracket 11, and the second clamping cylinder 22 is similarly bolted to the second connecting bracket 12.

[0028] The feeding tube 3 is located between the first clamping member 23 and the second clamping member 24, and a plastic bag is fitted on its lower part. When the system is running, the first clamping cylinder 21 and the second clamping cylinder 22 operate synchronously, driving the first clamping member 23 and the second clamping member 24 to move towards each other. With their synergistic effect, the packaging bag can be tightly clamped and fixed to the lower part of the feeding tube 3.

[0029] This meticulously designed clamping cylinder assembly 2 structure can firmly and stably fix the packaging bag to the discharge pipe 3 during the material discharge process, fundamentally eliminating the problem of material leakage caused by loose packaging bags, and providing reliable sealing guarantee for the entire packaging process.

[0030] The detection cylinder assembly 4 is described below, and it is located at the lower part of the clamping cylinder assembly 2. The detection cylinder assembly 4 specifically consists of a first detection cylinder 41, a second detection cylinder 42, a first detection probe 43, and a second detection probe 44. The first detection cylinder 41 is bolted to the lower part of the first clamping cylinder 21, and the second detection cylinder 42 is similarly bolted to the lower part of the second clamping cylinder 22. The first detection probe 43 is mounted on the first detection cylinder 41, and the second detection probe 44 is mounted on the second detection cylinder 42, with the first detection probe 43 and the second detection probe 44 positioned opposite each other.

[0031] The core function of this detection cylinder assembly 4 and its detection probes is to accurately detect whether the plastic bag is in place. The detection principle is based on the probes' conductivity to detect the presence of current. Since the plastic bag is an insulating material, when it is in place, it blocks the current path between the detection probes; conversely, if the plastic bag is not in place, current may exist between the probes. Therefore, if the detection probes detect no current, it indicates that the plastic bag is correctly placed, and the upper pneumatic butterfly valve will open, allowing material from the upper hopper to flow into the packaging bag. If current is detected, it means the plastic bag is not in place, and the upper pneumatic butterfly valve will close, preventing material from entering the packaging bag.

[0032] This ingenious design can accurately determine whether the plastic bag is in place, and only performs the feeding operation when the plastic bag is reliably in place. This fundamentally and significantly improves the accuracy and safety of the feeding operation, and effectively avoids material waste or other potential problems caused by the plastic bag not being in place.

[0033] Regarding the specific structure of the connecting brackets, both the first connecting bracket 11 and the second connecting bracket 12 consist of a vertical plate 111, a horizontal plate 112, and a connecting plate 113. One end of the connecting plate 113 is fixedly installed on the discharge pipe 3, and the other end is connected to the vertical plate 111. The lower part of the vertical plate 111 is connected to the horizontal plate 112, and the lower part of the horizontal plate 112 is connected to the clamping cylinder assembly 2. A reinforcing rib 114 is also provided between the vertical plate 111 and the horizontal plate 112. The scientific rationality of this carefully designed connecting bracket 1 is reflected in several aspects. The connecting plate 113 securely connects the discharge pipe 3 to the vertical plate 111, providing basic support for the entire connection structure. The vertical plate 111 and the horizontal plate 112 are perpendicularly connected to each other, forming a stable frame structure that can effectively distribute the force generated by the clamping cylinder assembly 2 during operation. The reinforcing rib 114 enhances the connection strength between the vertical plate 111 and the horizontal plate 112, preventing deformation due to stress during device operation. Through the close and coordinated cooperation between the vertical plate 111, the horizontal plate 112, the connecting plate 113, and the reinforcing rib 114, the stability and reliability of the entire device during operation are greatly ensured, ensuring that each component can continuously and stably perform its corresponding function, reducing the risk of failure due to structural instability.

[0034] The upper part of the discharge pipe 3 is equipped with a mounting flange 5, through which the discharge pipe 3 connects to the upper hopper, and the upper hopper is equipped with a pneumatic butterfly valve. The connection between the discharge pipe 3 and the upper hopper via the mounting flange 5 and the pneumatic butterfly valve facilitates precise control of material flow and cessation. When used in conjunction with a weighing sensor, it enables precise control of the packaged weight of the material.

[0035] In addition, the output end of the first clamping cylinder 21 is provided with a first piston rod 25, which is connected to the first clamping member 23; the output end of the second clamping cylinder 22 is provided with a second piston rod 26, which is connected to the second clamping member 24.

[0036] Both the first clamping member 23 and the second clamping member 24 consist of an arc-shaped clamping piece 231 and a clamping connecting block 232, with one side of the clamping connecting block 232 connected to the clamping cylinder. The arc-shaped clamping piece 231 better conforms to the shape of the packaging bag and the feeding tube, increasing the contact area with the packaging bag and allowing for more even pressure distribution during clamping, effectively preventing damage to the packaging bag due to excessive local pressure. The stable connection of the clamping connecting block 232 ensures that the power from the clamping cylinder is reliably transmitted to the clamping member. This structural design enables the first clamping member 23 and the second clamping member 24 to stably and firmly clamp the packaging bag during operation, ensuring the reliability and effectiveness of the bag clamping operation.

[0037] The working principle is as follows: Material first flows into the upper hopper, where its entry and exit are controlled by a pneumatic butterfly valve. During this process, the operator needs to place the packaging bag onto the discharge pipe 3. After placement, the operator triggers the sensor, at which point the first clamping cylinder 21 and the second clamping cylinder 22 work together to clamp the packaging bag. Subsequently, the first detection cylinder 41 and the second detection cylinder 42 extend, their detection probes used to detect whether current is flowing. If no current flows, the upper pneumatic butterfly valve opens, and material flows into the packaging bag. When the material weight reaches a predetermined value under the monitoring of the weighing sensor, the upper pneumatic butterfly valve closes. Finally, the operator ties the bag opening, covers it with a paper cap, and the material is transported away by the AGV.

[0038] The above are merely specific embodiments of this application, but the technical features of this application are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this application to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this application.
