Abstract
Description
Technical Field
[0001] This application relates to the field of titanium powder packaging equipment technology, and in particular to an automatic bagging device for titanium powder packaging. Background Technology
[0002] Titanium powder, as an important industrial raw material, possesses excellent properties such as low density, high strength, and strong corrosion resistance, and is widely used in aerospace, medical devices, chemicals, metallurgy, and many other fields. In the production and processing of titanium powder, the packaging stage is a crucial process to ensure safe transportation and stable storage. Its core requirements are accurate quantification, efficient bagging, and prevention of titanium powder dust pollution.
[0003] Currently, most existing titanium powder packaging equipment on the market suffers from the following problems: First, the bagging process has a low degree of automation, often requiring manual intervention in multiple stages such as material feeding start-up and shutdown, weighing calibration, and bag opening fixation. This not only increases labor costs but also easily leads to insufficient bagging weight accuracy due to human error, affecting product quality stability. Second, titanium powder has a certain degree of fluidity and fine particles. Existing equipment often uses a direct feeding method, which easily leads to material blockage or titanium powder splashing, resulting in material waste and pollution of the working environment. Third, there is insufficient coordination between various mechanisms. The processes of material feeding, weighing, bag opening, and conveying are not smoothly connected, resulting in low overall bagging efficiency and failing to meet the needs of large-scale titanium powder production line operations.

[0015] like Figure 1-7 As shown, this utility model discloses a technical solution: an automatic bagging device for titanium powder packaging, including a support frame 1. The support frame 1 is provided with a material conveying mechanism, a weighing mechanism, a bag supporting mechanism and a conveying mechanism from top to bottom.

The weighing sensors 8 are evenly distributed along the axis of the weighing hopper 7 and are tension sensors with an accuracy of ±0.1g, ensuring accurate weighing data. In this embodiment, three S-type tension sensors are selected and evenly distributed around the circumference of the weighing hopper 7. The upper end of the weighing hopper 7 is provided with a second inlet 10 corresponding to the position of the first discharge port 4. The diameter of the second inlet 10 is larger than that of the first discharge port 4 to prevent titanium powder from spilling. The lower end of the weighing hopper 7 is provided with a second discharge port 11, and two symmetrically arranged baffles 9 are rotatably connected to the second discharge port 11 by hinges. The edge of 9 is provided with a sealing strip, which can achieve a seal and prevent leakage when closed; the second drive assembly is provided with two sets, front and rear, each set including a first telescopic component 19, a U-shaped frame 20 and a first linkage plate 21. The first telescopic component 19 is a cylinder, which is vertically installed at the lower second discharge port 11 of the weighing hopper 7 through a bracket; the middle part of the U-shaped frame 20 is fixedly connected to the telescopic end of the first telescopic component 19 by a pin; there are two first linkage plates 21 on the left and right, one end of which is rotatably connected to the two ends of the U-shaped frame 20 through a rotating shaft.

The extension and retraction of the second telescopic component 22 drives the second linkage plate 23 and the third linkage plate 24 to rotate around the rotating rod, thereby driving the two clamping arc plates 14 to move relative to each other or towards each other, so as to achieve stable clamping or loosening of the bag opening of the packaging bag; The conveying mechanism includes a belt conveyor 17 installed at the bottom of the support frame 1. The conveyor belt of the belt conveyor 17 is made of anti-static material to prevent titanium powder from being attracted by static electricity. Its conveying speed can be adjusted by a frequency converter to adapt to different bagging efficiencies. Limiting baffles 27 are provided on both sides of the upper surface of the belt conveyor 17 along its length to limit and guide the packaging bags and prevent the packaging bags from shifting.
[0016] The working process of the automatic bagging device for titanium powder packaging provided by this utility model is as follows: 1. Equipment initialization: The operator pours the titanium powder to be packaged into the hopper above the storage hopper 3, places the opening of the empty packaging bag over the third discharge port 16 of the bag-supporting hopper 13, and starts the equipment through the PLC control system. 2. During the bag-opening action, the second telescopic component 22 of the third drive assembly retracts, causing the second linkage plate 23 and the third linkage plate 24 to rotate around the first rotating rod 25 and the second rotating rod 26, thereby driving the two clamping arc plates 14 to move relative to each other, clamping and fixing the bag opening to prevent it from falling off during the bagging process. 3. Material conveying and weighing: The two first drive motors 18 of the first drive assembly start, driving the two spiral augers 5 to rotate. The titanium powder in the storage hopper 3 enters the conveying cylinder 2, and after being graded and conveyed by the double spiral augers 5, it falls from the first discharge port 4 into the second feed port 10 of the weighing hopper 7. The weighing sensor 8 detects the weight of the titanium powder in the weighing hopper 7 in real time and transmits the data to the control system. When the weight reaches the preset value, the control system controls the first drive motor 18 to stop running, and the material conveying stops. 4. Material feeding and bagging: The first telescopic component 19 of the second drive assembly extends, pushing the U-shaped frame 20 downward. Through the first linkage plate 21, it drives the two gates 9 to rotate outward, opening the second feeding port 11. The titanium powder in the weighing hopper 7 enters the bag supporting hopper 13 through the second feeding port 11 and the third feeding port 15, and finally falls into the packaging bag from the third feeding port 16. After the feeding is completed, the first telescopic component 19 retracts, driving the gates 9 to close, completing one quantitative bagging. 5. Conveying and discharging: The second telescopic component 22 of the third drive assembly extends, driving the clamping arc plate 14 to move in opposite directions, releasing the packaging bag, and under the guidance of the limit baffle 27, it is conveyed to the next process (such as sealing and stacking), while the next packaging bag is bagged and bagged in a cycle.
[0017] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
