Description

Technical Field

[0001] The invention belongs to the technical field of packaging machinery, and in particular relates to an automatic switching shaping device of an open-mouth bag filling machine. Background Art

[0002] The aforementioned shaping device can also be called a forming device, which is used to integrate the material in the open bag filled by the filling machine into a rectangular shape under vibration, so as to facilitate stacking in logistics links such as warehousing and transportation without collapse.

[0003] The aforementioned open-mouth bags are widely used for packaging fine chemical raw materials such as ultrafine powders, metal ore and non-metallic ore powders, pharmaceutical chemical raw materials, dyes, pigments, calcium carbonate, kaolin, phenolic resins, and even powder or granular materials such as flour and seasonings in the food condiment category. Since the open-mouth bag filling machine has the advantages of high filling efficiency, accurate measurement, low manpower input, and helps to significantly reduce the work intensity of workers and improve the environment of the filling operation site, it is widely used in the production industry not limited to the aforementioned products.

[0004] A complete set of open-mouth bag filling machines usually includes: automatic quantitative weighing device, i.e. automatic quantitative scale, bag warehouse, automatic bag loading device, automatic bag clamping device, i.e. automatic bag mouth clamping device, automatic unloading device, automatic bag patting device, automatic loading trolley, automatic bag mouth sealing device, etc. The operation process of these devices is as follows: the automatic quantitative weighing device weighs quantitatively, the bag warehouse automatically provides empty open-mouth bags to be filled, the automatic bag loading device automatically extracts an empty open-mouth bag and feeds the extracted empty open-mouth bag to the automatic clamping device, the automatic clamping device clamps both sides of the bag mouth, and after the material weighed by the automatic quantitative weighing device is introduced into the open-mouth bag through the unloading device, the automatic bag patting device pats the bag to make the air mixed in the material leak out and make the material dense, and then the automatic bag holding device holds the filled open-mouth bag and delivers it to the automatic sealing introduction device, and the automatic sealing device seals it.

[0005] There is no lack of technical information related to open-mouth bag filling machines in the public Chinese patent documents, such as ZL201620205588.9 (bag clamping device of open-mouth bag automatic filling machine), ZL201620206148.5 (feeding device of open-mouth bag automatic filling machine), ZL201620205835.5 (automatic bag holding device of open-mouth bag), ZL20182162935.2 (a bag patting mechanism of a packaging machine), ZL2018216697 ...620205588.9 (a bag clamping device of an open-mouth bag automatic filling machine), ZL201620206148.5 (a material unloading device of an open-mouth bag automatic filling machine), ZL201620205835.5 (a bag patting mechanism of an open-mouth bag automatic filling machine), ZL20182162935.2 (a bag patting mechanism of a packaging machine), ZL2018216697 (a bag patting mechanism of a packaging machine), ZL2016202055888.9 (a bag clamping device of an open-mouth bag automatic filling machine), ZL201620206148.5 (a material unloading device of an open-mouth bag automatic filling machine), ZL201620205835. 80.8 (automatic unloading device for open-mouth bags with air-inflation sealing function for bag mouth), ZL201821669993.7 (vacuum extraction mechanism for automatic unloading device for open-mouth bags), ZL201822178209.3 (internal and external combined dust removal device for fully automatic open-mouth bag filling machine), ZL201920116357.4 (dust suction device for open-mouth bag filling machine) and ZL201920342830.0 (automatic clamping device for open-mouth bag filling machine), etc.

[0006] By reading the patent documents not limited to the above examples, it can be known that: in the process of the unloading device of the filling machine unloading the open-mouth bag, the other devices supporting the filling machine are basically in a temporary standby state. For example, during the period of filling the open-mouth bag, the vibration device and the full bag delivery device used to compact the material in the open-mouth bag are in a waiting state, so the action connection of the complete set of filling equipment cannot meet the expectations of the industry. Specifically, in the process of unloading the material by the unloading device, since the vibration device and the full bag delivery device of the subsequent station are in a waiting state, it is not conducive to improving the efficiency of the complete set of filling equipment and saving electric energy consumption. In addition, after the unloading mechanism completes the unloading of the open-mouth bag, the online operator needs to load the full bag of packaging bags into the shaping mold for shaping by the shaping mechanism of the shaping station, so the work intensity of the online operator is significantly increased. In view of the above, it is necessary to make improvements, and the technical solution to be introduced below is produced in this context. Summary of the invention

[0038] See you next time Figure 1 And combined with Figure 2 The aforementioned packaging bag material vibration mechanism 4 includes a vibration plate 41, a vibrator 42 and a pair of vibration spring sleeve fixing plates 43. The vibration plate 41 corresponds to the inner side of the aforementioned full bag packaging bag conveyor belt 33 in an up-and-down vibrating state and is located between the middle parts of the aforementioned conveyor frame left crossbeam 31 and the conveyor frame right crossbeam 32. The vibrator 42 is fixed on the side of the vibration plate 41 facing downward.

[0041] A mold frame front beam 62 is provided at the front end of the aforementioned switching shaping mold frame 6, a left connecting rod connecting seat 621 is fixed to the upper side of the left end of the mold frame front beam 62, and a right connecting rod connecting seat 622 is fixed to the upper side of the right end of the mold frame front beam 62, the left connecting rod connecting seat 621 is fixedly connected to the lower end of the aforementioned left connecting rod 56a, the right connecting rod connecting seat 622 is fixedly connected to the lower end of the aforementioned right connecting rod 56b, and the middle part of the mold frame front beam 62 is fixed to the front side of the aforementioned guide roller shaft fixing seat 57 through the guide wheel shaft fixing seat screw 623, and a shaping mold front support plate 63 and a shaping mold rear support plate 64 are provided in the middle part of the switching shaping mold frame 6.

[0042] When the left connecting rod lifting cylinder 54 and the right connecting rod lifting cylinder 55 are working (the two are working synchronously), for example, when the left connecting rod lifting cylinder column 541 and the right connecting rod lifting cylinder column 551 extend out of the cylinder body, that is, downward, the left connecting rod 56a is driven downward by the left connecting rod lifting cylinder column 541, and at the same time, the right connecting rod 56b is driven downward by the right connecting rod lifting cylinder column 551. Since the left connecting rod connecting seat 621 on the mold frame front beam 62 at the front end of the switching shaping mold frame 6 is fixedly connected to the lower ends of the left connecting rod 56a and the right connecting rod 56b, and since the right connecting rod connecting seat 622 on the mold frame front beam 62 is fixedly connected to the lower end of the right connecting rod 56b, when the left connecting rod 56a and the right connecting rod 56b are moved downward, the switching shaping mold frame 6 is driven downward, and as the switching shaping mold frame 6 is moved downward, the full bag packaging bag switching shaping mold 7 and the mouth clamping mechanism 8 are also moved downward accordingly, and vice versa.

[0043] In the present embodiment, the aforementioned left connecting rod lifting cylinder 54 and right connecting rod lifting cylinder 55 are pneumatic cylinders, but if oil cylinders are used, they should be considered equivalent.

[0044] See you next time Figure 1 And combined with Figures 2 to 3The aforementioned bag mouth clamping mechanism 8 includes a bag mouth rear clamping device 81 arranged on the aforementioned mold frame rear beam 65 and corresponding to the rear side of the aforementioned full bag packaging bag switching shaping mold 7, and a bag mouth front clamping device 82 arranged on the rear side of the aforementioned guide roller shaft fixing seat 57 and corresponding to the bag mouth rear clamping device 81 and having the same structure as the bag mouth rear clamping device 81 and corresponding to the front side of the full bag packaging bag switching shaping mold 7. The aforementioned bag mouth rear clamping device 81 includes a bag mouth rear clamping cylinder fixing seat support frame 811, a bag mouth rear clamping cylinder fixing seat 812, a bag mouth rear clamping cylinder 813, a bag mouth rear clamping rod fixing plate 814, and a bag mouth rear clamping rod fixing plate 815. The rear clamping rod 815 and a pair of rear guide rods 816, the lower end of the bag mouth rear clamping cylinder fixing seat support frame 811 is located in the middle of the aforementioned mold frame rear beam 65 at a position corresponding to the rear side of the aforementioned full bag packaging bag switching shaping mold 7, the bag mouth rear clamping cylinder fixing seat 812 is fixed to the bag mouth rear clamping cylinder fixing seat support frame 811, the bag mouth rear clamping cylinder 813 is fixed to the bag mouth rear clamping cylinder fixing seat 812 in a horizontal lying state, the bag mouth rear clamping cylinder column 8131 of the bag mouth rear clamping cylinder 813 faces forward, the middle of the bag mouth rear clamping rod fixing plate 814 and the end of the bag mouth rear clamping cylinder column 8131 are Figure 1 The front end of the bag mouth rear clamping rod is fixed in the state shown, and the left and right ends of the bag mouth rear clamping rod fixing plate 814 are respectively fixed to the front ends of a pair of rear guide rods 816, and the pair of rear guide rods 816 are slidingly matched with the aforementioned bag mouth rear clamping cylinder fixing seat 812, and the middle part of the length direction of the bag mouth rear clamping rod 815 is fixed to the bag mouth rear clamping rod fixing plate 814.

[0045] When the bag mouth rear clamping and releasing cylinder 813 is working, the bag mouth rear clamping and releasing cylinder column 8131 extends out of the cylinder body, driving the bag mouth rear clamping and releasing rod fixing plate 814, and the bag mouth rear clamping and releasing rod 815 fixed thereto is driven by the bag mouth rear clamping and releasing rod fixing plate 814. At the same time, the bag mouth front clamping and releasing device 82 is working at the same time, and the bag mouth front clamping and releasing rod 821 of the structural system of the bag mouth front clamping and releasing device 82 cooperates with the bag mouth rear clamping and releasing rod 815 to clamp the bag mouth of the full packaging bag 10. It can be seen from this that the actions of the bag mouth rear clamping and releasing rod 815 and the bag mouth front clamping and releasing rod 821 are manifested as displacement towards each other or synchronous repulsion from each other. Figure 1 and Figure 2 Also shown is the structural system of the bag mouth front clamping device 82 and the bag mouth front clamping cylinder fixing seat support frame 822 which is equivalent to the aforementioned bag mouth rear clamping cylinder fixing seat support frame 811 and is fixed on the rear side of the guide roller shaft fixing seat 57.

[0046] In this embodiment, the bag mouth front clamping action cylinder of the structural system of the aforementioned bag mouth rear clamping device 81 and the bag mouth front clamping device 82 adopts an air cylinder, but if an oil cylinder is used to replace the air cylinder, it should be regarded as an equivalent technical means.

[0047] The full bag packaging bag switching and shaping mold 7 mentioned repeatedly above is constituted by a bag cavity 71, and the bag cavity 71 passes through the upper part to the lower part of the full bag packaging bag switching and shaping mold 7; in addition, as a preferred scheme, a flexible sealing strip is inserted in the length direction of the aforementioned bag mouth rear clamping rod 815 and facing the front side, and the flexible sealing strip is a rubber strip, and the aforementioned bag mouth front clamping rod 821 is the same.

[0048] See also Figure 4 And combined with Figures 1 to 3 ,exist Figure 4 The open-mouth bag filling machine 9 mentioned above is shown in FIG. 1 , which has a frame 91 and a feeding mechanism (also called a filling mechanism), Figure 4 The automatic bag feeding device (not shown) belonging to the structural system of the open-mouth bag filling machine 9 feeds the empty open-mouth bag to be filled to the aforementioned unloading mechanism, and the bag clamping device matched to the unloading mechanism clamps the bag and opens the bag mouth, and then rises to the filling position to fill the open-mouth bag. Figure 4 The left and right displacement switching trolley frame 21 of the structural system of the automatic switching shaping device of the present invention on the left side of the position state shown is shifted to the right to the position corresponding to the unloading mechanism, and the unloading mechanism starts to fill the open-mouth bag and slowly descends together with the open-mouth bag, so that the open-mouth bag is sent to the aforementioned bag cavity 71, and the open-mouth bag is in a state of vibrating while filling. After the filling is completed, the aforementioned bag clamping device releases the bag mouth of the open-mouth bag, that is, releases the clamping of the bag mouth, and the bag mouth is clamped by the open-mouth bag clamping mechanism 8. At this time, the left and right displacement switching trolley frame 21 moves to the left, and the vibration ends. The vacuuming mechanism not shown in the figure descends, releases the bag mouth, vacuumizes, seals and the vacuuming mechanism rises, and the shaping mold frame 6 is switched to move upward. The full bag packaging bag is temporarily retained on the full bag packaging bag conveyor belt 33. The full bag packaging bag conveyor mechanism 3 works to move the full bag packaging bag conveyor belt 33 and deliver the full bag packaging bag 10. Then the shaping mold frame 6 is switched downward, and the aforementioned process begins to be repeated. When the left automatic switching shaping device of the present invention moves to the left, it is replaced by the right automatic switching shaping device and corresponds to the workstation corresponding to the open-mouth bag filling machine 9, and vice versa.

[0049] In summary, the technical solution provided by the present invention makes up for the shortcomings of the existing technology, successfully completes the invention task, and faithfully realizes the technical effects stated by the applicant in the technical effect column above.
