Description

Technical Field

[0001] This invention relates to the field of filling machine technology, and more specifically to a filling diversion mechanism and a filling machine containing the mechanism. Background Technology

[0002] In the filling production field, the filling diversion mechanism of a filling machine is a core component for achieving synchronous filling at multiple stations and improving production efficiency. Its performance directly determines filling accuracy, product consistency, and production stability. Currently, most filling diversion mechanisms on the market adopt a structure where a single main channel is diverted to multiple branch pipes to evenly distribute materials to each filling head, meeting the needs of large-scale production.

[0003] However, existing filling and diversion mechanisms generally suffer from pressure imbalance within the pipes. Due to differences in the geometric layout of the diversion pipes, shear losses during material flow, and inconsistent resistance in each branch pipe, even with a symmetrical flow channel design, it is difficult to achieve precise pressure balance within each branch pipe, resulting in deviations in the velocity and flow rate of the material in different branch pipes.

[0004] This pressure imbalance can trigger a series of production hazards: branches with excessively high pressure are prone to material splashing and overfilling, while branches with excessively low pressure can lead to underfilling and liquid level deviations, severely affecting product quality uniformity. Simultaneously, pressure imbalance can exacerbate pipeline wear, increase energy consumption, and even cause pipeline leaks due to localized excessive pressure, impacting production safety and continuity. Current technologies lack specific pressure regulation structures and cannot effectively solve this problem. Summary of the Invention

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.

[0023] The present invention will be further described below with reference to embodiments. Example 1:

[0024] refer to Figure 1 and Figure 2 A filling and diversion mechanism includes a feed pipe 1 and a diversion pipe assembly connected to the outlet end of the feed pipe 1 for diverting materials. Each diversion pipe assembly includes two diversion pipes. The diversion pipe assembly includes two first diversion pipes 2 connected to the outlet end of the feed pipe 1. The outlet end of each first diversion pipe 2 is connected to two second diversion pipes 3. The outlet end of each second diversion pipe 3 is provided with a second connecting pipe 12. An adjusting sleeve 13 is connected to the extrusion pipe 4. A first connecting pipe 11 adapted to the second connecting pipe 12 is slidably installed in the adjusting sleeve 13. The adjusting sleeve 13 is provided with a threaded hole. An adjusting rod 14 is threadedly installed in the threaded hole. The adjusting rod 14 is rotatably connected to the first connecting pipe 11. The cross-sectional area between the first connecting pipe 11 and the second connecting pipe 12 is adjusted by rotating the adjusting rod 14.

[0025] The material is continuously diverted through the feed pipe 1 to various diversion pipe groups, such as Figure 2As shown, the material in the feed pipe 1 continuously flows into the diversion pipe group to achieve the effect of uniform material distribution. At the same time, a measure to adjust the discharge rate is set between the first connecting pipe 12 and the second connecting pipe 13. By rotating the adjusting rod 14, the material passage cross section between the first connecting pipe 12 and the second connecting pipe 13 is adjusted to control the discharge speed. Example 2:

[0026] refer to Figure 3 and Figure 4 As shown, to ensure a more uniform feed rate in each distribution pipe, a flow balancing assembly is installed between the distribution pipe groups. This assembly includes a detection pipe 15 connected between each distribution pipe group, with each end of the detection pipe 15 connected to one of the two distribution pipes. The detection pipe 15 contains a detection element for detecting the pressure at both ends, and an adjusting plate 16 installed in the feed pipe 1. The angle of the adjusting plate 16 is adjusted according to the pressure difference between the two ends of the detection pipe 15. The detection element includes two detection airbags 17 installed at both ends of the detection pipe 15, with a feedback pipe 18 connecting the two detection airbags 17. Two first piston discs 19 are slidably installed in the feedback pipe 18, and the first piston discs 19 are connected to each other. A first connecting rod 20 is provided, and a feedback plate 21 is fixedly sleeved on the first connecting rod 20. The feedback plate 21 slides horizontally according to the pressure difference between the two detection airbags 17. The detection component also includes two elastic rods 22 installed on the outer walls on both sides of the feedback plate 21. The telescopic ends of the two elastic rods 22 are connected to the first contact electrode 23. Two second contact electrodes 24 are symmetrically slidably installed on the inner wall of the feedback tube 18. The first contact electrode 23 and the second contact electrode 24 are fully contacted by sliding the feedback plate 21. An adjuster 25 is provided in the feedback tube 18. The adjuster 25 is provided with a lever 26 for adjusting the gear. The lever 26 and the second contact electrode 24 are fixedly connected.

[0027] A detection tube 15 is installed between the two shunt tubes in the same group, such as... Figure 3 As shown, detection airbags 17 are provided at both ends of the detection tube 15. The pressure in the two first diversion tubes 2 is detected by the detection airbags 17. The internal pressure squeezes the detection airbags 17, causing the gas in the detection airbags 17 to enter the feedback tube 18. When the air pressure in the two first split pipes 2 is the same, the air pressure on the two first piston discs 19 is the same, so the two first piston discs 19 will not move, and the regulating plate 16 in the connected upper stage (intake pipe 1) will not rotate. When the air pressure in the two first split pipes 2 is different, the two first piston discs 19 will move towards the side with lower pressure, such as... Figure 4As shown in the enlarged view, when the first piston disc 19 moves, it drives the feedback plate 21 to slide. During the sliding process, the feedback plate 21 drives the first contact electrode 23 on one side to slide together. The first contact electrode 23 and the second contact electrode 24 make full contact, and the driving component (which can be a motor or other device) used to control the rotation of the regulating plate 16 is activated, so that the top of the regulating plate 16 deflects in the direction of greater pressure. In this way, more material enters the first diversion pipe 2 on the side with less pressure, thereby achieving the purpose of balancing the pressure.

[0028] It is worth noting that a flow balancing component can also be installed in the subsequent flow duct assembly to ensure that the pressure in each flow duct tends to be balanced, thereby achieving the effect of internal material balance. Example 3:

[0029] refer to Figures 5-7 To ensure more uniform material output during the extrusion process, the extrusion balancing assembly includes an extrusion tube 4 connected to the discharge end of the diversion tube assembly. The extrusion tube 4 contains an eccentrically rotating extrusion roller 5. Multiple scraper groups are elastically mounted on the extrusion roller 5, each containing multiple scrapers 6. The scrapers 6 in the same group are arranged spirally, and a balancing plate 28 is positioned between adjacent scrapers 6. The angle of the balancing plate 28 is adjusted according to the pressure difference between the surfaces of the two scrapers 6. Multiple adjustment grooves are provided on the extrusion roller 5, arranged spirally and staggered with the scrapers 6. A mounting frame 27 is slidably mounted in each adjustment groove. The balancing plate 28 is rotatably mounted on the mounting frame 27. A connecting plate 30 connects the mounting frame 27 to each of the two adjacent scrapers 6.

[0030] like Figure 5 As shown, multiple extrusion plates 6 are spirally arranged on the extrusion roller 5. The extrusion plates 6 are elastically installed, meaning that multiple grooves are spirally opened on the extrusion roller 5, and the extrusion plates 6 are slidably installed in the grooves. Because the extrusion roller 5 rotates eccentrically, the extrusion plates 6 on the side wall of the extrusion roller 5 will periodically generate extrusion force against the inner wall of the extrusion tube 4. The rotational force of the extrusion roller 5 comes from the material flowing into the extrusion tube 4 from the diversion tube. The flow of the material squeezes the outer wall of the extrusion plates 6, thereby driving the extrusion roller 5 to rotate. During the rotation of the extrusion roller 5, the material is also mixed to a certain extent. During the rotation, the extrusion plates 6 push the material and discharge it from the discharge hole 8, achieving the purpose of plastic strip.

[0031] refer to Figure 6 and Figure 7The mounting bracket 27 has a sliding plate 29 at its bottom, and the balance plate 28 has a rotating rod 31 at its bottom. A reversing groove is formed in the sliding plate 29, through which the rotating rod 31 rotates. A reversing plate 32 is fixedly mounted at the bottom end of the rotating rod 31. Two feedback chambers 33 are symmetrically formed in the sliding plate 29, and a second piston disc 34 is slidably mounted in each of the two feedback chambers 33. A second connecting rod 35 is mounted on each of the two second piston discs 34, and the second connecting rod 35 moves through the reversing groove and connects with the reversing plate 32. The slide plate 29 is movably connected to the plate 32. A first air hole 36 communicating with the feedback chamber 33 is opened on the slide plate 29. A pressure air bag is provided on the outer wall of the scraper 6. A second air hole 37 communicating with the pressure air bag is provided at the bottom of the scraper 6. The first air hole 36 and the second air hole 37 are connected. End heads 9 are installed at both ends of the extrusion tube 4. A rotating shaft 10 is rotatably installed in the end head 9. The rotating shaft 10 is fixedly connected to the non-center end of the extrusion roller 5. The extrusion tube 4 is connected to the discharge rack 7. The discharge rack 7 is provided with multiple discharge holes 8.

[0032] To improve the uniformity of the extruded material, a rotatable balance plate 28 is set between two adjacent extrusion plates 6. It is worth noting that the number of extrusion plates 6 is even, and two adjacent extrusion plates 6 form a group. A balance plate 28 is configured in one group of extrusion plates 6.

[0033] Two extrusion plates 6 in the same group are equipped with pressure bladders on their rotating surfaces. When the two pressure bladders rotate with the extrusion plates 6, they are squeezed by the internal material. The two pressure bladders are compressed and contracted, and the internal air is transmitted to the feedback chamber 33 through the first air hole 36 and the second air hole 37. Two feedback chambers 33 are set in the slide plate 29. When the pressure difference between the two extrusion plates 6 is small, the second piston disc 34 in the two feedback chambers 33 will not slide significantly. When the pressure difference between the two extrusion plates 6 is large, the second piston disc 34 slides to the side with lower pressure, thereby causing the second connecting rod 35 to push the reversing plate 32 to rotate. This, in turn, through the rotation rod 31 and the balance plate 28, guides more material to the extrusion plate 6 with lower pressure, thus making the pressure in the extrusion tube 4 more balanced and the extruded material more uniform.
