Description

Technical Field

[0001] This utility model relates to the field of bag-opening packing technology, specifically a high-stability bag-opening packing device based on vacuum adsorption. Background Technology

[0002] Open-bag packing typically refers to the process in industrial or engineering fields of removing pre-packaged packing materials (such as random packing, structured packing, etc.) from their packaging bags and filling them into designated equipment (such as towers, reactors, absorption towers, etc.). High-stability open-bag packing devices are automated or semi-automated equipment specifically designed for industrial packing processes, solving problems such as low efficiency, poor stability, and dust pollution associated with traditional manual open-bag packing. This device not only provides safety protection but also improves packing efficiency. When feeding materials, because the materials consist of fine particles, these particles are prone to over-accumulation during transport, preventing the materials from being smoothly conveyed to the designated location and significantly reducing the device's production efficiency.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 201621444265.1, application date 20-0-1) provides an automatic feeding device, including a raw material tank, an extruder, a die machine, a material bucket, a feed pipe, a vacuum tube, a vacuuming mechanism, and a collection tank. The raw material tank includes a stirring mechanism, which includes a stirring rod and a stirring motor. The stirring rod passes through the top of the raw material tank and extends to the lower middle part of the raw material tank. The stirring motor drives the stirring rod to rotate inside the raw material tank. The collection tank includes a filter element and a baffle plate. The filter element is connected to the outlet of the collection tank. The baffle plate extends inward from the inner wall side of the collection tank, and the baffle plate and the inner wall of the collection tank form an internal vacuum channel for gas flow at the inlet of the collection tank. This automatic feeding device uses the baffle plate to block the resin powder, and the filter element to block it again, so that the powder is deposited for collection, preventing excessive accumulation of fine powder from clogging the vacuum tube, thereby improving production efficiency and reducing enterprise production costs.

[0004] Optimizing the piping of the device can not only reduce the resistance to gas flow, but also enable the vacuum adsorption pump to build up the required negative pressure at the suction cup more quickly. This means that the device can grab packaging bags more quickly, shorten the time of each work cycle, and improve overall production efficiency. During the use of the above device, the inability to optimize the negative pressure piping led to frequent shutdowns, a significant increase in packaging material consumption, and a substantial reduction in device capacity.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: By using the conveying assembly 2, frame 1, and vacuum adsorption pump 4, the negative pressure pipeline can be optimized, and the downtime rate can be reduced. Figures 1-3 As shown: It includes a frame 1, with one end of a conveying assembly 2 slidably connected to the lower right side of the frame 1, and the other end of the conveying assembly 2 slidably connected to a packing frame 3. A vacuum adsorption pump 4 is fixedly connected to the lower right side of the packing frame 3, and a packing assembly 5 is fixedly connected to the inner wall of the packing frame 3. A fixed plate 14 is reciprocally slidably connected to the inner wall of the frame 1, and a limit rod 15 is fixedly connected to the surface of the fixed plate 14. A screening assembly 16 is slidably connected through the limit rod 15, and the screening assemblies 16 are evenly distributed on the surface of the limit rod 15. A feeding box 6 is fixedly connected to the upper end of the frame 1, and a moving plate 26 is fixedly connected to the inner wall of the frame 1 near the feeding box 6. A sliding rod 18 is fixedly connected to the surface of the moving plate 26, and a baffle plate 25 is slidably connected through the sliding rod 18.

[0029] The worker places the material to be processed into the feeding hopper 6. The material begins to flow downwards under its own weight, and the worker starts the motor 7, causing the baffle plate 25 to slide back and forth at the lower end of the feeding hopper 6 to prevent blockage (e.g., Figure 3As shown), it ensures that the material is evenly distributed inside the frame 1, guaranteeing a smooth feeding process. Simultaneously, the motor 7 drives the screening assembly 16 to slide inside the frame 1, screening the falling material using different specifications of screening assemblies 16. Material meeting the requirements continues to fall through the screening assembly 16 (e.g., ...). Figure 3 As shown), large particles or impurities that do not meet the particle size requirements will be screened out to ensure the consistency of material quality and allow qualified materials to quickly enter the packaging process, increasing the output per unit time. After screening, the material is conveyed to the inside of the packing frame 3 through the conveying component 2 (as shown). Figure 1 and Figure 2 As shown), the filling assembly 5 bags the material, while the vacuum adsorption pump 4 optimizes the negative pressure pipeline, reduces downtime, reduces packaging material waste, increases the production capacity of the equipment, reduces labor costs, and improves the accuracy of bag opening and printing.

[0030] In Example 2, unlike Example 1, the use of protrusions 13, drive shafts 11, and fixing posts 17 ensures the consistency of material quality and allows qualified materials to quickly enter the packaging process. Figures 4-5 As shown: A motor 7 is fixedly connected to the upper surface of the frame 1, and a fixing block 9 is fixedly connected to the end of the upper surface of the frame 1 near the feeding box 6. A rotating shaft 8 is rotatably installed inside the fixing block 9. The output end of the motor 7 is fixedly connected to the rotating shaft 8. A transmission shaft 11 is rotatably installed inside the frame 1. A bevel gear 10 is fixedly connected to both the surface of the transmission shaft 11 and the surface of the rotating shaft 8. A connecting plate 12 is fixedly connected to the surface of the transmission shaft 11. A protrusion 13 is fixedly connected to the lower surface of the connecting plate 12. The lower surface of the protrusion 13 is arc-shaped. The connecting plate 12 is rotatably installed inside the frame 1. A fixing column 17 is fixedly connected inside the screening component 16. The upper end of the fixing column 17 is arc-shaped. A force plate 20 is fixedly connected to the inner wall of the frame 1. One end of a fixing spring 19 is fixedly connected to the upper surface of the force plate 20. The other end of the fixing spring 19 is fixedly connected to the fixing column 17.

[0031] When the motor 7 is working, it drives the output shaft 8 to rotate inside the fixed block 9, and through the bevel gear 10 on the surface of the shaft 8 and the transmission shaft 11, the motor 7 drives the transmission shaft 11 to rotate inside the frame 1 (e.g., Figure 4 As shown), the drive shaft 11 drives the connecting plate 12 on the surface to rotate inside the frame 1. As the connecting plate 12 rotates, the protrusion 13 at the lower end of the connecting plate 12 pushes the fixed column 17 to slide inside the frame 1. At the same time, the fixing spring 19 at the end of the fixed column 17 retracts towards the surface of the force plate 20, causing the fixed column 17 to drive the screening assembly 16 on the surface to rotate and slide back and forth inside the frame 1 (as shown). Figure 5As shown, this increases output per unit time, reduces downtime or adjustments caused by material issues, maintains a stable production rhythm, and improves overall production efficiency.

[0032] In embodiment three, unlike embodiment two, the connecting block 21, cylinder 23, and connecting rod 24 are used to prevent the material feeding box 6 from becoming clogged and to ensure that the material is evenly distributed inside the frame 1. Figures 6-7 As shown: A connecting block 21 is fixedly connected to one end of the inner wall of the frame 1 near the baffle 25, and a connecting shaft 22 is rotatably installed inside the connecting block 21. Belts are fitted onto both the surface of the connecting shaft 22 and the surface of the rotating shaft 8. A cylinder 23 is fixedly connected to the surface of the connecting shaft 22, and the cylinder 23 is rotatably installed inside the frame 1. One end of a connecting rod 24 is slidably connected to the surface of the cylinder 23, while the other end of the connecting rod 24 is slidably connected to the baffle 25.

[0033] A belt is connected to the surface of the connecting shaft 22 and the surface of the rotating shaft 8. Through belt drive, the motor 7 drives the connecting shaft 22 to rotate inside the connecting block 21 when it is working (e.g., Figure 6 As shown), the rotation of the connecting shaft 22 causes the cylinder 23 on the surface to rotate inside the frame 1, and the cylinder 23 causes the connecting rod 24 on the surface to slide on the front side, so that the connecting rod 24 causes the baffle 25 at the other end to slide on the surface of the sliding rod 18, thereby causing the baffle 25 to slide at the lower end of the feeding box 6 (as shown). Figure 7 As shown in the figure, this ensures a smooth feeding process and prevents excessive material impact on the inner wall of the feeding box 6, reducing wear on the inner wall and lowering the cost of replacing parts due to equipment damage.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
