Description

Technical Field

[0001] The utility model relates to the field of packaging equipment, in particular to a large bag-feeding packaging machine. Background Art

[0002] The structure of a general bag-feeding packaging machine includes a dividing turntable, on which a first bag-clamping assembly is evenly distributed around the circumference is installed. The first bag-clamping assembly passes through a bag-loading station, a bag-opening station, and a material-feeding station in sequence, and is finally transferred to another dividing turntable. A vacuum chamber is evenly distributed around the circumference of the other dividing turntable. After the vacuum cover of the vacuum chamber is opened, the bag containing the material is transferred to the vacuum chamber and the cover is closed. The bag is evacuated in the vacuum chamber and then sealed. If such a bag-feeding packaging machine is used for packaging bags weighing more than 5 kilograms and with large bag specifications, if it is redesigned, the vacuum chamber needs to be designed to be large enough, so the dividing turntable also needs to be designed to be a large-specification turntable, which takes up a lot of space and requires a very large increase in manufacturing costs. At the same time, after the material is bagged, the packaging bag will be stretched, deformed, or even torn by gravity. At the same time, the first bag-clamping assembly will not be able to clamp such a heavy bag. This will cause the loaded packaging bag to be unable to be transferred stably and smoothly due to its heavy weight, thereby affecting the packaging yield. Utility Model Content

[0027] The present invention is described in detail below through examples, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

Under each first bag clamping assembly 3, there is a load-bearing support plate 4 that can be raised and lowered, and the load-bearing support plate 4 is connected to the graduated turntable 2 through a bracket 5. Figure 7 As shown, the bracket 5 is provided with a vertical guide rod 6, which is mounted on an adjustment seat 7. The load-bearing support plate 4 is fixed to the adjustment seat 7, and the adjustment seat 7 is locked at the height by a loose screw. This design allows the support position to be adjusted according to different bag heights, preventing the bag from stretching and deforming due to heavy materials.

[0029] Specific as Figure 3 、 Figure 4As shown, a vacuum sealing device 9 is installed on the side of the frame 1, and a transfer device 10 is provided between the vacuum sealing device 9 and the dividing turntable 2. The transfer device 10 includes a first linear motion module 11 mounted between the two, a slide 12 is installed on the module guide rail, and a top plate 13 is fixed below the slide 12. Four guide columns 14 arranged in a matrix are provided on the top plate 13, and a lifting plate 15 is slidably connected to the guide columns 14. A lifting cylinder 16 is installed on the top of the top plate 13, and its piston rod is connected to the lifting plate 15. A clamping mechanism is provided on the front side of the lifting plate 15, which includes a first fixed clamping plate 17 and a first movable clamping plate 18. The first movable clamping plate 18 is connected to the first rocker arm 20 through a rotating shaft 19, and the end of the first rocker arm 20 is hinged to the piston rod of the clamping cylinder 21 to realize the opening and closing of the clamping claws.

[0030] Specific as Figure 2 As shown, the vacuum sealing device 9 includes a platform 22, on which two sets of vacuum components are arranged in parallel. Each set of components includes a vacuum chamber 23 and a cover 24. A longitudinal guide rail 26 is provided on the surface of the platform 22, and a transverse second linear motion module 25 is installed on the guide rail slider 27. The two covers 24 are fixed on the module slide 28. A telescopic cylinder 29 is provided at the rear of the platform 22, and its piston rod is connected to the second linear motion module 25 to realize the front, back, left and right compound movement of the cover 24. An input channel 30 is formed between the two vacuum chambers 23, and the first linear motion module 11 of the transfer device 10 and the material conveyor belt 49 are arranged opposite to the channel.

[0031] Specific as Figure 5 、 Figure 6 As shown, a second bag clamping assembly 31 is provided on both sides of the top of the inner cavity of the cover 24, comprising a second fixed splint 32 and a second movable splint 33. The second movable splint 33 is connected to the second rocker arm 35 through a rotating shaft 34, and the second rocker arm 35 is connected to the movable cylinder 36 on the outer wall of the cover 24. A bag holding assembly 37 is provided below the inner cavity of the cover 24, comprising an upper horizontal shaft 38, a lower horizontal shaft 39, a bag holding plate 40 and a bag holding cylinder 41. The upper horizontal shaft 38 fixes the bag holding plate 40, and the lower horizontal shaft 39 is connected to the bag holding plate 40 through a swing arm 42 and a hinged plate 43.

A heat sealing assembly 45 is also installed in the cover 24, comprising a heating plate 47 driven by a heat sealing cylinder 46, which forms a heat sealing alignment mechanism with the bottom plate 48 in the vacuum chamber 23.

[0032] Working Principle: After the indexing turntable 2 drives the first bag clamping assembly 3 to complete bag loading, bag opening, and material loading in sequence, the load-bearing support plate 4 supports the bottom of the bag to prevent sagging and deformation of the packaging bag. The clamping mechanism of the transfer device 10 clamps the bag and moves it horizontally along the first linear motion module 11 and the material conveyor belt 49 (which supports the packaging bag for transportation) to the input channel 30. At the same time, the lifting cylinder 16 adjusts the transfer height. The cover 24 is moved to the docking position by the second linear motion module 25 and the telescopic cylinder 29. The bag support plate 40 rises to support the bag, and the second bag clamping assembly 31 clamps the bag opening. After the cover 24 closes the vacuum chamber 23, the vacuum pump draws vacuum, and the heat sealing assembly 45 completes the sealing. The cover then leaves the vacuum chamber, and the finished product slides out from the inclined surface at the bottom of the vacuum chamber to the blanking port of the frame and falls, and is output through the finished product conveyor belt below the blanking port to complete the operation. In this way, the two sets of vacuum components work alternately. When one cover 24 is performing vacuuming, the other cover 24 returns to the material receiving position, forming a continuous production rhythm.
