Description

Technical Field

[0001] This utility model relates to the technical field of liquid strip packaging filling equipment, specifically to a compressed air blowing vibration device for a liquid strip packaging filling machine. Background Technology

[0002] During the operation of a liquid strip packaging filling machine, the upper horizontal seal is pulled downwards to form the film while filling. Due to various factors such as the physical properties of the liquid, viscosity, static electricity generated during film pulling, and the smoothness of the inner film of the packaging material, some liquid droplets adhere to the horizontal seal position. When the horizontal seal is applied, the droplets vaporize at high temperature, forming liquid trapping. This results in incomplete film sealing, leakage, affecting product quality, causing waste of defective products, and increasing production costs and personnel sorting costs. Therefore, it is necessary to provide a compressed air blowing vibration device for the liquid strip packaging filling machine to solve the liquid trapping problem during the liquid strip packaging production process. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a compressed air blowing vibration device for a liquid strip filling machine, which ensures that the inner film surface of the liquid strip at the horizontal sealing position is dry, avoids liquid droplet residue causing liquid droplet vaporization during high-temperature sealing to form liquid trapping, and prevents leakage due to poor sealing, which affects the quality.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A compressed air blowing vibration device for a liquid strip filling machine includes an upper horizontal seal and a blowing vibration mechanism fixed below the upper horizontal seal. The blowing vibration mechanism includes a blowing pipe horizontally arranged along the length of the upper horizontal seal. Multiple blowing branch pipes are connected to the bottom of the blowing pipe at an angle downwards. The lower end of the blowing branch pipe is inclined toward the side of the upper horizontal seal where the material outlet is located, so that the lower end of the blowing branch pipe is located directly below the material outlet.

[0005] In one embodiment of this utility model, multiple liquid strips are vertically lowered from the feed port and correspond one-to-one with the air outlet at the lower end of the blowing branch pipe.

[0006] In one embodiment of this utility model, one end of the air blowing pipe is connected to the air inlet pipe via a regulating valve, and the air inlet pipe is connected to an air compressor.

[0007] In one embodiment of this utility model, an exhaust mechanism is fixedly connected to the bottom of the upper horizontal seal, and the air blowing vibration mechanism is fixedly connected to the bottom of the exhaust mechanism.

[0008] As one embodiment of the present invention, the exhaust mechanism includes a square-shaped exhaust frame and a compression mechanism disposed within the exhaust frame. The compression mechanism includes two sets of exhaust components disposed along the width direction of the exhaust frame. Each set of exhaust components includes several vertically disposed exhaust shafts and mounting plates connected to both ends of the exhaust shafts. The exhaust shafts are rotatably connected to the mounting plates.

[0009] In one embodiment of this utility model, the distance between the two sets of exhaust components is adjustable. An adjusting block is fixedly connected to the outside of the mounting plate. The adjusting block has a threaded hole along the width direction of the exhaust frame, and the spiral directions of the threaded holes on the mounting plates at the same end of the two sets of exhaust components are opposite. An adjusting screw is internally threaded into the threaded hole on the mounting plate at the same end of the two sets of exhaust components. The adjusting screw has external threads with opposite spiral directions. One end of the adjusting screw is rotatably connected to the inner wall of the exhaust frame, and the other end passes through the side wall of the exhaust frame and is connected to the adjusting handle.

[0010] In one embodiment of this utility model, the extrusion mechanism is symmetrically arranged in two sets along the length direction within the exhaust frame.

[0011] In one embodiment of this utility model, the two ends of the air blowing pipe in the air blowing vibration mechanism are fixedly connected to the bottom of the exhaust frame in the exhaust mechanism by connecting blocks; the air blowing pipe is fixed by welding, bonding or bolting after passing through the connecting block, and the connecting block is welded or bolted to the bottom of the exhaust frame.

[0012] In one embodiment of this utility model, the two ends of the exhaust frame in the exhaust mechanism are fixed to the bottom of the upper horizontal seal by connecting plates.

[0013] In one embodiment of this utility model, the upper horizontal seal can move up and down via a lifting device provided at its rear; a lower horizontal seal is also provided below the air blowing vibration mechanism.

[0014] The beneficial effects of adopting the above technical solution are as follows: The compressed air blowing vibration device for liquid strip filling machine provided by this utility model has an air blowing vibration mechanism set below the upper horizontal seal. Through independent air blowing branch pipes corresponding to each liquid strip, it ensures uniform airflow distribution, improves vibration effect, and makes each row of liquid strips vibrate evenly. This can effectively vibrate and slide off the liquid droplets adhering to the inner film of the liquid strip, ensuring that the inner film surface at the horizontal seal position of the liquid strip is dry. It avoids liquid droplet residue causing liquid droplet vaporization and liquid trapping during high-temperature sealing, and prevents leakage due to poor sealing, which affects quality.

[0015] The air-blowing vibration device generates vibration by providing power through compressed air, causing droplets adhering to the inner membrane of the liquid strip package to slide off, thus solving the liquid trapping problem in liquid strip package filling machines. Statistical analysis shows that the liquid trapping rate has decreased from 2.0% to 0.04%. With an annual production capacity of approximately 300 million units, there have been no reports of liquid trapping or leakage, fully demonstrating the effectiveness and practicality of this design and resolving the quality risks associated with liquid trapping and leakage during production.

[0023] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0024] like Figures 1-6 The liquid strip filling machine shown includes a compressed air blowing vibration device, comprising an upper horizontal seal 100 and a blowing vibration mechanism 300 fixedly connected below the upper horizontal seal 100. The blowing vibration mechanism includes a blowing pipe 7 horizontally arranged along the length of the upper horizontal seal 100. Multiple blowing branch pipes 10 are connected to the bottom of the blowing pipe 7 at an angle downwards. The lower ends of the blowing branch pipes 10 are inclined towards the side of the upper horizontal seal 100 where a material outlet 16 is located, so that the lower ends of the blowing branch pipes 10 are directly below the material outlet 16. The blowing pipe 7 and the blowing branch pipes 10 are made of stainless steel or aluminum alloy.

[0025] In this embodiment, multiple liquid strips 15 are vertically lowered from the feed port 16 and correspond one-to-one with the air outlet at the lower end of the air blowing branch pipe 10.

[0026] One end of the air blowing pipe 7 is connected to the air pipe 9 via a regulating valve 8, and the air pipe 9 is connected to an air compressor.

[0027] As a further optimization, such as Figure 1 and Figure 2 As shown, an exhaust mechanism 200 is fixedly connected to the bottom of the upper horizontal seal 100, and the blowing vibration mechanism 300 is fixedly connected to the bottom of the exhaust mechanism 200.

[0028] Specifically, such as Figures 4-6 As shown, the exhaust mechanism 200 includes a rectangular exhaust frame 1 and a compression mechanism disposed within the exhaust frame 1. The compression mechanism includes two sets of exhaust components arranged along the width direction of the exhaust frame 1. During production, the liquid strip 15 passes between the two sets of exhaust components and is compressed and discharged by the exhaust shaft 3. Each set of exhaust components includes several vertically arranged exhaust shafts 3 and mounting plates 2 connected to both ends of the exhaust shafts 3. The exhaust shafts 3 are rotatably connected to the mounting plates 2. In this embodiment, each set of exhaust components includes three vertically and evenly arranged exhaust shafts 3.

[0029] As a further optimization, the spacing between the two sets of exhaust components is adjustable, which can be used to exhaust liquid strips 15 of different thicknesses. An adjusting block 4 is fixedly connected to the outside of the mounting plate 2. The adjusting block 4 has threaded holes along the width direction of the exhaust frame 1, and the threaded holes on the mounting plates 2 at the same end of the two sets of exhaust components have opposite spiral directions. An adjusting screw 5 is internally threaded into the threaded holes on the mounting plates 2 at the same end of the two sets of exhaust components. The adjusting screw 5 has external threads with opposite spiral directions at its front and rear ends, respectively screwed into the two threaded holes on the two mounting plates 2 at the same end of the two sets of exhaust components. One end of the adjusting screw 5 is rotatably connected to the inner wall of the exhaust frame 1, and the other end passes through the side wall of the exhaust frame 1 and is connected to the adjusting handle 6. The spacing between the two sets of exhaust components can be adjusted by rotating the adjusting handle 6. In this embodiment, the extrusion mechanism is symmetrically arranged in two sets along the length direction within the exhaust frame 1 to prevent the exhaust shaft 3 from becoming too long and heavy, increasing rotational resistance. Simultaneously, when adjusting the spacing between the two sets of exhaust components, the error caused by the low straightness of the exhaust shaft 3 is reduced, which is beneficial for improving accuracy.

[0030] In this embodiment, the two ends of the air blowing pipe 7 in the air blowing vibration mechanism 300 are fixedly connected to the bottom of the exhaust frame 1 in the exhaust mechanism 200 by connecting blocks 11; the air blowing pipe 7 is fixed by welding, bonding or bolting after passing through the connecting blocks 11, and the connecting blocks 11 are welded or bolted to the bottom of the exhaust frame 1. The two ends of the exhaust frame 1 in the exhaust mechanism 200 are welded or bolted to the bottom of the upper horizontal seal 100 by connecting plates 12.

[0031] The upper horizontal seal 100 can move up and down via a lifting device 13 located at its rear; a lower horizontal seal 400 is also located below the air blowing vibration mechanism 300. Both the lifting device 13 and the lower horizontal seal 400 are fixedly mounted on the filling machine frame. The lifting device 13 includes a lifting plate 14 fixed to the rear of the upper horizontal seal 100. The lifting plate 14 has a vertically arranged threaded hole, and a lead screw 13 is fitted into the threaded hole. The upper end of the lead screw 13 is rotatably mounted on a fixed plate 18, and the lower end is connected to the output shaft of a servo motor 17. The servo motor 17 is a geared servo motor. The fixed plate 18 is fixedly connected to the filling machine frame, and one lifting device 13 is located on each side of the rear of the upper horizontal seal 100.

[0032] In the exhaust mechanism 200, an air blowing pipe 7 with a length of about 90cm is fixedly connected to the bottom of the exhaust frame 1. The air blowing pipe 7 has an outer diameter of 16mm and an inner diameter of 12mm. The lower part of the air blowing pipe 7 is connected to 12 air blowing branch pipes 10. The air blowing branch pipes 10 have an outer diameter of 4mm and an inner diameter of 3mm. The 12 independent air blowing branch pipes 10 correspond to 12 liquid strips 15 respectively. During the production process, each row of liquid strips 15 is straightened, and compressed air is sent to the air blowing pipe 7 after being regulated by the regulating valve 8. It is then discharged through the air blowing branch pipes 10, which causes each row of liquid strips 15 to vibrate under force. This can effectively vibrate and slide off the liquid droplets stuck on the inner membrane of the liquid strips 15, preventing liquid from getting trapped and causing leakage due to poor sealing.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
