A rapid packing control device for a packing machine

Abstract

This utility model discloses a rapid packaging control device for a packaging machine. The rapid packaging control device features a first and second fixed plate on the discharge pipe providing structural support. An electric push rod drives the lifting and lowering of the cover plate. An annular tube is connected to an external vacuum cleaner via a suction head, allowing for real-time extraction of dust escaping from the bag opening during filling. The inner support plate expands synchronously outward via a drive assembly, opening the bag opening and forming a semi-enclosed space with the cover plate. This dual action effectively intercepts and absorbs dust, completely solving the pollution problem caused by dust dispersion in traditional filling processes and the respiratory health risks to operators. A vibration component inside the base drives a rotating shaft via a motor and a bevel gear set. The protrusion on the top surface of the turntable periodically collides with the protrusion on the bottom surface of the support plate, causing the support plate to vibrate at high frequency. This compacts the powder inside the bag, reduces air gaps, improves the accuracy of the filling amount, and avoids packaging bulging or insufficient quantity caused by powder settling during transportation.

Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a rapid packaging control device for a packaging machine. Background Technology

[0002] In the field of powder material production and packaging, baling machines are core equipment for achieving quantitative powder filling and improving packaging efficiency, and are widely used in industries such as food, chemicals, and pharmaceuticals. Existing powder baling machines typically convey powder quantitatively into packaging bags through a filling outlet, completing the packaging process such as weighing, filling, and sealing, which basically meets the efficiency requirements of large-scale production.

[0003] However, existing packaging machines have significant drawbacks in the filling process: when powder falls from the discharge port into the packaging bag, due to gravity and air turbulence, a large amount of dust rises back and drifts into the surrounding environment from the bag opening. This drifting dust gradually forms serious dust pollution, affecting the air quality of the production workshop. More importantly, long-term exposure to dust can easily cause respiratory diseases, allergies, and other health problems for operators, posing occupational health and safety hazards.

[0004] Therefore, developing a rapid packaging control device for packaging machines that can effectively suppress dust dispersion, ensure operational safety, and not affect packaging efficiency has become an urgent need to improve the environmental friendliness and safety of powder packaging operations. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a rapid packaging control device for a packaging machine that can suppress dust dispersion, ensure operational safety, and not affect packaging efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A rapid packing control device for a baling machine includes a base, a baling machine body mounted on the base, a hopper mounted on the baling machine body, and a discharge pipe mounted on the discharge end of the hopper. A first fixed plate and a second fixed plate are sequentially arranged from top to bottom on the discharge pipe. A cover plate is mounted on the bottom surface of the first fixed plate via multiple electric push rods. The cover plate is movably installed inside the discharge pipe, and an annular tube is fixedly mounted on the cover plate. The annular tube is connected to an external vacuum cleaner via a flexible hose. Multiple vacuum heads are arrayed on the annular tube and installed inside the cover plate. Multiple sliding grooves are arrayed on the second fixed plate, and sliders are slidably arranged within the grooves. An inner support plate is fixedly mounted on the slider. The inner support plate has an arc-shaped structure and is concentrically arranged with the inner wall of the cover plate. A drive assembly is also provided between the second fixed plate and the first fixed plate to drive the multiple inner support plates to move synchronously towards or away from the axis of the discharge pipe.

[0008] Preferably, the drive assembly includes a movable tube and multiple push-pull rods. The movable tube is movably mounted on the discharge tube and concentrically fixed inside the cover plate. The sidewall of the movable tube is connected to multiple sliders one-to-one through multiple push-pull rods, wherein both ends of the push-pull rods are hinged.

[0009] Preferably, multiple reinforcing ribs are also arranged in an array between the first fixed plate, the second fixed plate and the side wall of the discharge pipe, and the reinforcing ribs are in the form of a triangular structure.

[0010] Preferably, a partition is fixedly installed inside the base, and a support plate is movably installed on the partition via a telescopic unit. A vibration component for driving the support plate to vibrate is also installed inside the base.

[0011] Preferably, the vibration component includes a rotating shaft, a turntable, protrusions, and a bevel gear set. The rotating shaft is rotatably mounted on the partition plate, and the rotating shaft is connected to a motor installed in the base through the bevel gear set. A turntable is also fixedly mounted on the top of the rotating shaft. Multiple protrusions are fixedly provided on the top surface of the turntable and the bottom surface of the support plate. The protrusions have a hemispherical structure and are arranged in a ring array.

[0012] Preferably, the telescopic unit includes telescopic rods movably installed at the four corners of the partition. One end of the telescopic rod is fixedly connected to the bearing plate, and the other end is equipped with a baffle. A spring is also sleeved on the rod body between the bearing plate and the partition.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) The first and second fixed plates on the discharge pipe of this utility model provide structural support. The electric push rod drives the cover plate to rise and fall. The annular pipe is connected to an external vacuum cleaner through the dust suction head. During filling, the dust escaping from the bag opening can be extracted in real time. The inner support plate expands outward synchronously through the drive component. While opening the bag opening, it forms a semi-enclosed space with the cover plate. The dual function effectively intercepts and absorbs dust, completely solving the pollution problem caused by dust dispersion in traditional filling and the respiratory health hazards of operators.

[0015] (2) The shaking component in the base of this utility model is driven by a motor through a bevel gear set to rotate the shaft. The top surface protrusion of the turntable collides periodically with the bottom surface protrusion of the support plate, causing the support plate to shake at high frequency. This can compact the powder in the bag, reduce air gaps, improve the accuracy of filling amount, and avoid packaging swelling or insufficient amount caused by powder settling during transportation.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0024] Example 1

[0025] like Figure 1-6As shown, the packaging machine rapid packaging control device provided by this utility model includes a base 1, a packaging machine body 2 mounted on the base 1, a hopper 3 mounted on the packaging machine body 2, and a discharge pipe 4 mounted on the discharge end of the hopper 3. A first fixed plate 5 and a second fixed plate 6 are sequentially arranged from top to bottom on the discharge pipe 4. The first fixed plate 5 and the second fixed plate 6 provide structural support. A cover plate 9 is mounted on the bottom surface of the first fixed plate 5 via multiple electric push rods 7. The electric push rods 7 control the lifting and lowering of the cover plate 9. The cover plate 9 is movably installed inside the discharge pipe 4, and an annular pipe 10 is fixedly mounted on the cover plate 9. The annular pipe 10 is connected to an external vacuum cleaner via a flexible hose 11. Multiple suction heads 12 are arrayed on the annular pipe 10. The suction heads 12 extract loose powder during filling. The dust suction head 12 is installed inside the cover plate 9. The second fixed plate 6 has multiple grooves 13 arranged in an array. A slider 14 is slidably arranged in the grooves 13. An inner support plate 15 is fixedly arranged on the slider 14. The inner support plate 15 abuts against the inner wall of the packaging bag and opens the bag opening. The inner support plate 15 is concentrically arranged with the inner wall of the cover plate 9. A drive assembly is also provided between the second fixed plate 6 and the first fixed plate 5 to drive the multiple inner support plates 15 to move synchronously towards or away from the axis of the discharge pipe 4. When the drive assembly drives the multiple inner support plates 15 to move synchronously towards the axis of the discharge pipe 4, the bag opening is opened. At the same time, the inner support plate 15 contacts the inner wall of the cover plate 9 to achieve a semi-closed structure. When the dust rushes out from the bag opening, the dust suction head 12 absorbs the dust and solves the problem of dust pollution.

[0026] Example 2

[0027] Please see Figure 3 and Figure 4 The drive assembly includes a movable tube 16 and multiple push-pull rods 17. The movable tube 16 is movably mounted on the discharge tube 4 and concentrically fixed inside the cover plate 9. The side wall of the movable tube 16 is connected to multiple sliders 14 one-to-one through multiple push-pull rods 17. Both ends of the push-pull rods 17 are hinged. When the cover plate 9 is raised or lowered, the movable tube 16 links with the push-pull rods 17 to synchronously drive the inner support plate 15 to extend and retract. No additional power source is required, ensuring the synchronicity of the bag opening and the semi-sealing of the top of the bag opening.

[0028] Example 3

[0029] Please see Figure 2 Multiple reinforcing ribs 8 are also arranged in an array between the first fixed plate 5, the second fixed plate 6 and the side wall of the discharge pipe 4. The reinforcing ribs 8 are triangular in structure to enhance the support stability.

[0030] Example 4

[0031] Please see Figure 5 and Figure 6The base 1 is fixedly provided with a partition 18, and a carrier plate 19 is movably provided on the partition 18 through a telescopic unit. The carrier plate 19 is used to place packaging bags. The base 1 is also provided with a shaking component that drives the carrier plate 19 to shake, wherein the shaking component reduces the gap of powder inside the bag.

[0032] Example 5

[0033] Please see Figure 5 and Figure 6 The vibration assembly includes a rotating shaft 20, a turntable 23, protrusions 24, and a bevel gear set 21. The rotating shaft 20 is rotatably mounted on the partition plate 18, and is connected to a motor 22 installed in the base 1 via the bevel gear set 21. A turntable 23 is fixedly mounted on the top of the rotating shaft 20. Multiple protrusions 24 are fixedly provided on the top surface of the turntable 23 and the bottom surface of the support plate 19. The multiple protrusions 24 are arranged in a circular array. When the rotating shaft 20 is driven to rotate, the turntable 23 rotates simultaneously. The protrusions 24 on the turntable 23 and the protrusions 24 on the bottom surface of the support plate 19 are staggered. In conjunction with the telescopic unit, the support plate 19 vibrates up and down, generating vibration to compact the powder.

[0034] Example 6

[0035] Please see Figure 6 The telescopic unit includes telescopic rods 25 movably installed at the four corners of the partition 18. One end of the telescopic rod 25 is fixedly connected to the bearing plate 19, and the other end is equipped with a baffle. A spring 26 is also sleeved on the rod body of the telescopic rod 25 located between the bearing plate 19 and the partition 18. The spring 26 provides elastic reset and buffering for the bearing plate 19.

[0036] Working principle:

[0037] During filling, the electric push rod 7 pushes the cover plate 9 downwards, and the cover plate 9 drives the movable tube 16 to move downwards simultaneously. The movable tube 16, through the push-pull rod 17, pushes multiple inner support plates 15 outwards to tighten the bag opening. At this time, the discharge pipe 4 begins to discharge material, and the external vacuum cleaner is activated, extracting dust from the bag opening through the hose 11, the annular tube 10, and the suction head 12. After filling, the electric push rod 7 retracts, causing the cover plate 9 to rise. The movable tube 16, in conjunction with the push-pull rod 17, pulls the inner support plates 15 inwards to loosen the bag opening. In addition, during the filling process, the motor 22 inside the base 1 drives the rotating shaft 20 and the turntable 23 to rotate through the bevel gear set 21. The top protrusion 24 of the turntable 23 periodically collides with the bottom protrusion 24 of the support plate 19, causing the support plate 19 to vibrate at high frequency under the support of the telescopic rod 25 and the spring 26, thus compacting the powder inside the bag and reducing the air content. This design solves the problem of dust dispersion during powder filling in the background technology by combining "bag opening sealing and dust suction" with "powder compaction and shaking" to ensure a clean working environment and the health and safety of operators.

[0038] The motor and electric actuator involved in the embodiments, along with their supporting control system, electromagnetic switch, and pipeline circuit, can also be provided by the manufacturer. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0039] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
