Description

Technical Field

[0001] This application relates to the field of packaging bag filling technology, and in particular to a bag material beating and combing device. Background Technology

[0002] On packaging production lines for powdery, granular, or strip-shaped materials, after the materials are filled into bags, problems such as incomplete filling, uneven distribution, or adhesion often occur, affecting the quality and appearance of the finished product. To solve this problem, beating or combing devices are often used to perform external mechanical treatment on the packaging bags.

[0003] Existing tapping devices mostly use fixed taps or simple swinging mechanisms, with fixed swing amplitude, tapping height, and spacing between the two taps. This means that a single device is often only suitable for packaging bags of specific sizes and filling heights, resulting in poor versatility. When the production line changes product specifications or packaging bag sizes, it requires stopping the machine and performing complex mechanical adjustments or even replacing the entire tapping assembly, severely impacting production efficiency and increasing equipment costs and maintenance complexity.

[0004] Therefore, there is an urgent need in this field for a bag material beating and combing device with flexible and rapid adjustment of both height and spacing to meet the high-efficiency, multi-variety, and flexible production needs of modern production lines. Summary of the Invention

[0005] The purpose of this application is to provide a bag material beating and combing device to solve the above problems. It can adapt to the beating needs of packaging bags of different specifications, effectively solve problems such as incomplete powder filling and sticky strip materials, and has the advantages of convenient adjustment, wide applicability and good beating effect.

[0006] This application achieves the above objectives through the following technical solutions: A bag material beating and combing device, comprising: The rotating support unit includes a vertically arranged support shaft and a bearing fixedly sleeved on the support shaft; The striking unit includes at least two pillars rotatably mounted on the outer ring of the bearing via a collar, and two opposing and reciprocating striking plates mounted on the pillars, with a channel between the striking plates for the passage of the packaging bag. A drive unit is used to drive the collar to perform reciprocating rotational motion, thereby causing the tapping unit to swing back and forth to tap the packaging bag located in the channel; A height adjustment mechanism is provided between the support column and the collar for adjusting the vertical height of the clapper. A spacing adjustment mechanism is provided between the clapper and the support column to adjust the spacing between the two clappers.

[0007] In some embodiments, the height adjustment mechanism includes: a height adjustment elongated hole constructed vertically on the support column, and a height fastener passing through the height adjustment elongated hole and securing the support column to the collar.

[0008] In some embodiments, the spacing adjustment mechanism includes: a clapper support disposed on the side of the clapper facing away from the channel, a spacing adjustment elongated hole constructed in the horizontal direction on the clapper support, and a spacing fastener passing through the spacing adjustment elongated hole and fastening the clapper support to the support column.

[0009] In some embodiments, the driving unit includes: An electric motor with an eccentric wheel mounted on its output shaft; An eccentric shaft, which is connected to the eccentric wheel and offset from the rotation center of the eccentric wheel; The linkage mechanism has a first end hinged to the eccentric shaft and a second end fixedly connected to the collar, used to convert the rotational motion of the motor into the reciprocating rotational motion of the collar.

[0010] In some embodiments, the linkage mechanism includes: The first connecting rod has its first end hinged to the eccentric shaft; The second connecting rod has its first end hinged to the second end of the first connecting rod via a connecting shaft, and its second end fixedly connected to the collar.

[0011] In some embodiments, the clapper is an arc-shaped plate or a flat plate.

[0012] In some embodiments, a support shaft mounting base is further included for mounting the support shaft, the support shaft mounting base being fixed to the bottom end of the support shaft and having mounting holes.

[0013] In some embodiments, the system further includes a support frame, the top of which is fixed with a motor mounting plate for mounting the motor, and the bottom of which is fixed with a motor mounting base.

[0014] In some embodiments, the collar is coaxially fixed to the outer ring of the bearing by mounting rings and fasteners provided at both ends.

[0015] Compared with the prior art, this application achieves the following beneficial effects: By setting up height adjustment mechanism and spacing adjustment mechanism, operators can easily and quickly adjust the working height of the clapper and the working spacing between the two clappers, so that the same device can perfectly adapt to a variety of packaging bags of different sizes and filling heights, greatly improving the versatility of the equipment and the flexibility of the production line.

[0016] The drive unit, consisting of a motor, eccentric wheel, and linkage mechanism, can efficiently convert the motor's circular motion into the powerful reciprocating oscillation required by the clapper. The clapping action is strong and stable, effectively compacting powder and breaking up sticky strips of material, ensuring that the contents of the packaging bag are full and uniform.

[0017] The support column is mounted on the bearing via a collar, ensuring smooth oscillation and firm support for the striking unit. The adjustment mechanism uses a combination of elongated holes and fasteners, resulting in a simple structure, high reliability, and easy adjustment—simply tightening or loosening the bolts is required, making operation very convenient and saving adjustment time.

[0022] Examples, such as Figure 1-3As shown, a bag material beating and combing device includes a support rotation unit, a beating unit, a drive unit, a height adjustment mechanism, and a spacing adjustment mechanism.

[0023] The rotating support unit includes a vertically arranged support shaft 1 and a bearing 2 fixedly sleeved on the support shaft 1; it also includes a support shaft mounting base 11 for mounting the support shaft 1, the support shaft mounting base 11 being fixed to the bottom end of the support shaft 1 and having mounting holes; it also includes a stand 19, the top end of which is fixed with a motor mounting plate 12 for mounting the motor 13, and the bottom end of which is fixed with a motor mounting base 20; the collar 3 is coaxially fixed to the outer ring of the bearing 2 by mounting rings and fasteners at both ends. The rotating support unit includes a support shaft 1 and a bearing 2. The support shaft 1 is vertically arranged, and its bottom end is fixed to the ground or equipment base by a support shaft mounting base 11, which has mounting holes and can be fixed by anchor bolts. The bearing 2 is fixedly sleeved on the upper middle part of the support shaft 1, and a collar 3 is coaxially fixed to its outer ring. The collar 3 has mounting rings at both ends, which are fastened to the outer ring of the bearing 2 by fasteners such as bolts, so that the collar 3 can rotate smoothly relative to the support shaft 1.

[0024] The tapping unit includes at least two support columns 4 rotatably mounted on the outer ring of the bearing 2 via a collar 3, and two opposing tapping plates 8 mounted on the support columns 4 and capable of reciprocating. A channel for the passage of a packaging bag is formed between the tapping plates 8. The tapping plates 8 can be curved or flat. The tapping unit comprises two support columns 4 and two tapping plates 8. The two support columns 4 are symmetrically arranged around the collar 3 and connected to the collar 3 via a height adjustment mechanism. The tapping plates 8 can be curved or flat, mounted on the support columns 4 via tapping plate supports 7. The two tapping plates 8 are positioned opposite each other, forming a channel for the passage of a packaging bag.

[0025] A drive unit is used to drive the collar 3 to reciprocate in rotation, thereby causing the striking unit to swing back and forth to strike the packaging bag located in the channel. The drive unit includes: a motor 13 with an eccentric wheel 14 mounted on its output shaft; an eccentric shaft 15 connected to the eccentric wheel 14 and offset from the rotation center of the eccentric wheel 14; and a linkage mechanism, the first end of which is hinged to the eccentric shaft 15 and the second end of which is fixedly connected to the collar 3, for converting the rotational motion of the motor 13 into the reciprocating rotational motion of the collar 3. The linkage mechanism includes: a first link 16 with its first end hinged to the eccentric shaft 15; and a second link 17 with its first end hinged to the second end of the first link 16 via a connecting shaft 18 and its second end fixedly connected to the collar 3. The drive unit includes a motor 13, an eccentric wheel 14, an eccentric shaft 15, and a linkage mechanism. The motor 13 is fixed to the top of a support frame 19 via a motor mounting plate 12. A motor mounting base 20 is provided at the bottom of the support frame 19 to enhance stability. An eccentric wheel 14 is mounted on the output shaft of the motor 13. An eccentric shaft 15 is connected to the eccentric wheel 14 and offset from its center of rotation. The linkage mechanism includes a first link 16 and a second link 17: the first end of the first link 16 is hinged to the eccentric shaft 15, and the second end is hinged to the first end of the second link 17 via a connecting shaft 18; the second end of the second link 17 is fixedly connected to a collar 3.

[0026] A height adjustment mechanism is disposed between the support column 4 and the collar 3 for adjusting the vertical height of the clapper 8. The height adjustment mechanism includes: a height adjustment elongated hole 5 vertically disposed on the support column 4, and a height fastener 6 passing through the height adjustment elongated hole 5 and securing the support column 4 to the collar 3. The height adjustment mechanism includes a height adjustment elongated hole 5 vertically disposed on the support column 4, and a height fastener 6, such as a bolt or nut, passing through the hole and securing the support column 4 to the collar 3. Loosening the height fastener 6 allows the support column 4 to slide up and down to adjust the working height of the clapper 8; after adjustment, tightening the height fastener 6 secures the clapper.

[0027] A spacing adjustment mechanism is disposed between the clapper 8 and the support column 4 to adjust the spacing between the two clappers 8. The spacing adjustment mechanism includes: a clapper support 7 disposed on the side of the clapper 8 facing away from the channel; a horizontally oriented elongated hole 9 for adjusting the spacing; and a spacing fastener 10 passing through the elongated hole 9 and securing the clapper support 7 to the support column 4. The spacing adjustment mechanism includes a clapper support 7 disposed on the side of the clapper 8 facing away from the channel; a horizontally oriented elongated hole 9 for adjusting the spacing; and a spacing fastener 10, such as a bolt or nut, passing through the hole and securing the clapper support 7 to the support column 4. Loosening the spacing fastener 10 allows the clapper support 7 to slide horizontally, adjusting the spacing between the two clappers 8 to accommodate packaging bags of different widths; after adjustment, tightening the spacing fastener 10 secures the clappers.

[0028] Working principle: The motor 13 is started, which drives the eccentric wheel 14 to rotate, thereby driving the eccentric shaft 15 to perform circular motion. The eccentric shaft 15 drives the first connecting rod 16 to reciprocate, and the first connecting rod 16, in turn, drives the second connecting rod 17 to oscillate through the connecting shaft 18. The oscillation of the second connecting rod 17 is ultimately converted into a pushing and pulling force on the collar 3, driving the collar 3 to reciprocate around the support shaft 1 at a certain angle. The reciprocating rotation of the collar 3 drives the two support pillars 4 and the clappers 8 on them to oscillate synchronously. When the packaging bags on the conveyor line pass through the channel between the two clappers 8, they are hit by the reciprocating clappers 8, thereby completing the sorting, compaction or dispersal of the material inside the bag.

[0029] In some embodiments, the main difference between this embodiment and Embodiment 1 lies in the form of the clapper structure. In this embodiment, the clapper 8 adopts a flat plate structure, a thin-walled structure, and is made of 304 stainless steel. The surface of the flat plate is sandblasted to a surface roughness Ra=3.2μm to increase the friction with the packaging bag.

[0030] The installation method of the flat clapper is the same as that of the curved clapper, but a rubber shock-absorbing pad with a thickness of 5mm is added between the clapper support 7 and the clapper 8 to reduce the impact noise during clapping. Other structures and adjustment methods are exactly the same as in implementation method one.

[0031] In some embodiments, the main difference between this embodiment and Embodiment 1 lies in the driving method. This embodiment uses a pneumatic drive device instead of a motor drive, including components such as a rotary cylinder, a reversing valve, and a throttle valve. The cylinder body of the rotary cylinder is mounted on a support shaft, and the output end of the rotary cylinder is connected to the end of the collar 3. The rotary cylinder supports the support column 4 and the beater 8, and can drive the beater 8 to reciprocate about the axial direction of the collar 3.

[0032] The advantage of pneumatic drive devices lies in their excellent explosion-proof performance, making them suitable for locations with explosion-proof requirements. Other structural and adjustment methods are the same as in implementation method one.

[0033] In some embodiments, this embodiment focuses on handling fragile materials or irregularly shaped bags.

[0034] Clapper plate structure: Clapper plate 8 is made of flexible materials, such as polyurethane or rubber sheet, with an internal metal frame to ensure support strength.

[0035] Spacing adjustment mechanism: Upgraded to automatic adjustment. The spacing fastener 10 has been replaced with a screw mechanism with a handwheel. Rotating the handwheel can drive the two paddle supports 7 to move synchronously in opposite directions, and the spacing value is displayed in real time via a scale, making adjustment more precise and effortless.

[0036] The gentle tapping action minimizes damage to materials and packaging bags, while the precise and efficient spacing adjustment makes it suitable for packaging lines of high-end, fragile materials.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
