Description

Technical Field

[0001] This invention relates to the field of bag material conveying technology, and in particular to a conveying device for a bag material packaging machine in intelligent packaging equipment. Background Technology

[0002] Conveying devices are required in bag packaging. They are the core transmission units that connect bag material storage, packaging processing and finished product output. They are designed to achieve automated and high-precision bag material transfer and adapt to the packaging needs of granular, powder and block bag materials in multiple industries such as food, chemical and pharmaceutical.

[0003] In the prior art, Chinese patent document CN120207905A discloses a conveying device for a bag packaging machine of special intelligent packaging equipment, including a side panel, a bracket fixedly connected to the left side of the side panel, a motor fixedly connected to the inner wall of the bracket, a rotating shaft one fixedly connected to the output end of the motor, a conveyor belt driven by the circumferential surface of the rotating shaft one, a rotating shaft two driven by the inner wall of the conveyor belt, an inner plate fixedly connected to the side of the side panel away from the motor, a support plate fixedly connected to the bottom of the side panel, a guiding mechanism provided at the top of the conveyor belt, a cleaning mechanism provided on the inner wall of the support plate, and a collecting mechanism provided on the inner wall of the support plate. By preventing goods from shifting or getting stuck on both sides of the conveyor belt during transportation, thus affecting the shipment, it also reduces damage to the equipment and improves production efficiency.

[0004] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: In the scenario of bag packaging and conveying, due to the limitations of the height of packaging equipment and the layout of factory space, the transfer of bag materials from high to low places often adopts the use of slide conveyor. However, slides not only have a high space occupancy rate, but also have significant defects. As the bag material slides down the slide, its speed continuously increases due to gravity. When it reaches the bottom, it is easy to impact and collide with the edge of the downstream conveying device due to inertia, which can lead to problems such as damage to the packaging bag and leakage of materials, which have an adverse impact on the integrity of packaging and production continuity. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that in the existing technology, the high-to-low conveying of bag material packaging is limited by the height of the equipment and the layout of the factory. This method takes up space and the bag material is easily damaged by the inertia of the downward slide. Therefore, we propose a conveying device for bag material packaging machine of intelligent packaging equipment.

[0006] To achieve the above objectives, this application adopts the following technical solution: a conveying device for a bag packaging machine for intelligent packaging equipment, comprising an upper conveyor, an intelligent transfer machine and a lower conveyor, wherein the intelligent transfer machine includes a drive assembly and a support assembly is provided on the upper part of the drive assembly; The support assembly includes a bracket, a side plate, and a support plate. The side plate is fixedly connected to both sides of the bracket, and the support plate is rotatably connected to the inner side of the side plate. A flipping assembly is provided on the outer surface of the bracket, a centering assembly is provided on the side edge of the side plate, and a rolling assembly is provided inside the support plate. The flipping assembly includes a first inclined rod hinged to the lower surface of the support plate. The end of the first inclined rod away from the support plate is movably connected to a connecting rod. The outer surface of the connecting rod is movably connected to a second inclined rod. The end of the second inclined rod away from the connecting rod is hinged to a hollow frame plate. Both the connecting rod and the hollow frame plate are slidably connected to the outer surface of the side plate. Preferably, the drive assembly includes a platform disposed between the upper conveyor and the lower conveyor, a hydraulic telescopic rod disposed in the middle of the platform, a central rod rotatably connected to the top of the hydraulic telescopic rod, a bracket fixedly connected to the top of the central rod, and a rotating mechanism disposed at the top of the hydraulic telescopic rod for driving the central rod and the bracket to rotate.

[0007] Preferably, a worm gear is movably provided on the side plate of the bracket, and spur gears are fixedly connected to both ends of the worm gear. A turntable is movably inserted in the middle of the bracket, and a worm wheel is fixedly connected to one end of the turntable that passes through the bracket. The worm wheel meshes with the worm gear.

[0008] Preferably, a rack column is fixedly connected to the upper surface of the platform, and the rack column is meshed with a spur gear.

[0009] Preferably, a lever is fixedly connected to the outer surface of the turntable, and the lever is slidably connected inside the hollow frame plate.

[0010] Preferably, the centering component includes a slider that is movably inserted in the middle of the side plate, the portion of the slider near the support plate being configured as a semi-circular block, and a shaft being provided in the middle of the end of the slider extending out of the side plate.

[0011] Preferably, a vertical plate is fixedly connected to the upper surface of the side plate, and a push rod is movably inserted through the outer surface of the vertical plate. A clamping plate is fixedly connected to the end of the push rod near the support plate, and a tail plate is fixedly connected to the end of the push rod away from the clamping plate.

[0012] Preferably, the outer surface of the side plate is provided with a support, and a rocker arm is movably sleeved on the outer surface of the support. The top end of the rocker arm is hinged to the lower surface of the tail plate, and the other end of the rocker arm is sleeved on the outer surface of the shaft.

[0013] Preferably, a spring is fixedly connected to the outer surface of the slider, and the end of the spring away from the slider is fixedly connected to the outer surface of the side plate.

[0014] Preferably, the rolling assembly includes a roller shaft rotatably connected inside the support plate, the outer surface of the roller shaft having a ring array of strip grooves, and ball bearings rotatably connected inside the strip grooves.

[0015] The technical effects and advantages of this invention are as follows: In this invention, during high-low position transfer, the hydraulic telescopic rod pulls the support down, the spur gear meshes with the rack and pinion to rotate, and drives the turntable to rotate via the worm gear and worm wheel. The support plate is flipped through the hollow frame plate, inclined bar, and connecting rod, and the bag material slides down the plate into the lower conveyor. The equipment occupies a much smaller area than the traditional slide, and the impact force between the bag material and the equipment during transfer is greatly reduced, which can effectively ensure the integrity of the packaging bag and meet the needs of efficient and low-damage bag material transfer. In this invention, when the intelligent transfer machine support plate flips from tilted to horizontal, the two side edges push the slider to slide, and at the same time the shaft drives the rocker arm to rotate. The tail plate and push rod drive the symmetrical clamping plate to move towards the center, so as to achieve precise centering of the bag material. This ensures that the bag material is in the center position when it falls into the lower conveyor, effectively avoiding scratches and damage with the edge of the conveyor, ensuring the integrity of the bag material transfer, and adapting to the high-precision and low-loss bag material conveying requirements.

[0018] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0019] Reference Figures 1 to 8 As shown, the present invention provides a technical solution: a conveying device for a bag packaging machine for intelligent packaging equipment, including an upper conveyor 1, an intelligent transfer machine 2 and a lower conveyor 3. The intelligent transfer machine 2 includes a drive component 4, and a support component 5 is provided on the upper part of the drive component 4. The support assembly 5 includes a bracket 51, a side plate 52, and a support plate 53. The side plate 52 is fixedly connected to both sides of the bracket 51, and the support plate 53 is rotatably connected to the inner side of the side plate 52. The outer surface of the bracket 51 is provided with a flipping assembly 6, the side of the side plate 52 is provided with a centering assembly 7, and the inside of the support plate 53 is provided with a rolling assembly 8.

[0020] In the post-processing stage of bag material in intelligent packaging equipment, when the packaged bag material needs to be transferred from the upper conveyor 1 to the lower conveyor 3, a dedicated smooth transfer system is required to achieve a damage-free connection. The bag material is first output from the upper conveyor 1 and falls into the support plate 53. At this time, the support plate 53 is aligned with the conveying surface of the upper conveyor 1 and is in an initial upward tilted posture. Under the action of inertia, the bag material slides along the inclined surface to the inner positioning area of ​​the support plate 53. Subsequently, the drive component 4 receives the linkage signal, which on the one hand drives the bracket 51 to complete a 180-degree rotation, and on the other hand pulls the bracket 51 to move downward along the preset trajectory, so as to gradually reduce the transfer height. At the same time, the flipping component 6 drives the support plate 53 to gradually flip downward around the rotation axis through linkage, so that the support plate The conveying surface 53 and the conveying surface of the lower conveyor 3 form a smooth transition angle. During this process, the centering component 7 aligns the bag material on the support plate 53, and ensures that the bag material is always in the center position of the conveyor through symmetrical thrust, avoiding deviation and collision. When the support plate 53 flips to a state of complete contact with the lower conveyor 3, the bag material falls smoothly onto the conveying surface of the lower conveyor 3. The entire process achieves impact-free transfer between high and low positions, greatly reducing the contact impact force between the bag material and the equipment, and effectively ensuring the integrity of the packaging bag. In addition, the rolling component 8 embedded inside the support plate 53 can convert sliding friction into rolling friction during the centering and sliding process of the bag material, significantly reducing frictional resistance, ensuring smooth and uninterrupted movement of the bag material, and further improving the transfer efficiency and stability.

[0021] Reference Figures 1 to 3 As shown, the drive assembly 4 includes a frame 41 disposed between the upper conveyor 1 and the lower conveyor 3. A hydraulic telescopic rod 42 is disposed in the middle of the frame 41. A central rod 43 is rotatably connected to the top of the hydraulic telescopic rod 42. A bracket 51 is fixedly connected to the top of the central rod 43. A rotating mechanism 44 is disposed at the top of the hydraulic telescopic rod 42. The rotating mechanism 44 is used to drive the central rod 43 and the bracket 51 to rotate. The rotating mechanism 44 includes a motor mounted on the top of the hydraulic telescopic rod 42. A drive wheel is disposed at the top of the motor. A driven wheel is disposed on the outer surface of the central rod 43. In the high-low position transfer stage of the intelligent packaging equipment, when the packaged bag material is transferred from the upper conveyor 1 to the lower conveyor 3, it first falls precisely into the receiving support plate 53 along the conveying trajectory of the upper conveyor 1. Then, the motor receives the control signal and starts, driving the drive wheel to rotate at a preset speed. The drive wheel drives the driven wheel to rotate synchronously, which in turn drives the center rod 43, which is coaxially connected to the driven wheel, to rotate at a uniform speed. During the rotation of the center rod 43, it synchronously drives the support component 5, which is rigidly connected to it, to complete a 180-fold rotation, so that the support plate 53 smoothly switches from the initial receiving posture to the transfer posture aligned with the lower conveyor 3. Immediately afterwards, the hydraulic telescopic rod 42 extends and retracts precisely under the drive of the hydraulic system, pulling the bracket 51 to move downward along the guide rail, while driving the support plate 53 to slowly rotate around the rotation axis until the conveying surface of the support plate 53 and the conveying surface of the lower conveyor 3 form a smooth transition. Under the action of gravity and slight thrust, the bag material falls smoothly into the lower conveyor 3, realizing shock-free transfer.

[0022] Reference Figures 3 to 5 As shown, the flipping assembly 6 includes a first inclined rod 68 hinged to the lower surface of the support plate 53. The end of the first inclined rod 68 away from the support plate 53 is movably connected to a connecting rod 69. The outer surface of the connecting rod 69 is movably connected to a second inclined rod 610. The end of the second inclined rod 610 away from the connecting rod 69 is hinged to a hollow frame plate 66. Both the connecting rod 69 and the hollow frame plate 66 are slidably connected to the outer surface of the side plate 52. The side plate 52 of the bracket 51 is movably provided with a worm gear 61. Both ends of the worm gear 61 are fixedly connected to spur gears 62. A turntable 64 is movably inserted in the middle of the bracket 51. One end of the turntable 64 that passes through the bracket 51 is fixedly connected to a worm wheel 65. The worm wheel 65 meshes with the worm gear 61. The upper surface of the platform 41 is fixedly connected to a rack column 63. The rack column 63 meshes with the spur gear 62. The outer surface of the turntable 64 is fixedly connected to a lever 67. The lever 67 is slidably connected inside the hollow frame plate 66.

[0023] In the core process of intelligent transfer machine 2 for high-low transfer of bagged materials, when the hydraulic telescopic rod 42 pulls the bracket 51 downward along the guide column under the precise control of the hydraulic station, the spur gear 62 moves downward synchronously and gradually meshes with the fixed rack column 63. Under the axial limiting action of the rack column 63, the spur gear 62 rotates along its own axis during the downward movement. Its output shaft is rigidly connected to the worm gear 61 through a coupling, thereby driving the worm gear 61 to rotate synchronously. The worm gear 61 and the worm wheel 65 form a reduction transmission mechanism. When the worm gear 61 rotates, it drives the worm wheel 65 to rotate slowly. The inner hole of the worm wheel 65 is connected to the turntable 64 through a key to realize torque transmission, driving the turntable 64 to rotate slowly and uniformly. The lever 67 near the edge of the turntable 64 moves in a circular motion with the turntable 64, pushing the hollow frame plate 66. Moving upward along the vertical guide rail, the outer surface of the hollow frame plate 66 is hinged to the second inclined rod 610 via bearings. The other end of the second inclined rod 610 is movably connected to the connecting rod 69. Under the tension of the hollow frame plate 66, the connecting rod 69 slides horizontally along the linear slide rail built into the side plate 52. The middle section of the connecting rod 69 is hinged to the support plate 53 via the first inclined rod 68. Finally, it pulls the support plate 53 to slowly flip downward around the hinge axis between it and the side plate 52. When the support plate 53 flips and tilts downward, the bag material slides down along the support plate 53 under the action of gravity and finally falls smoothly into the lower conveyor 3. This intelligent transfer machine 2, through the coordination of mechanical transmission and hydraulic control, greatly reduces the equipment footprint compared to the traditional slide rail, and significantly reduces the contact impact force between the bag material and the equipment during the transfer process, effectively ensuring the integrity of the packaging bag.

[0024] Reference Figures 5 to 7 As shown, the centering component 7 includes a slider 71 that is movably inserted in the middle of the side plate 52. The part of the slider 71 near the support plate 53 is set as a semi-circular block. A shaft 72 is set in the middle of the end of the slider 71 that extends out of the side plate 52. A vertical plate 75 is fixedly connected to the upper surface of the side plate 52. A push rod 76 is movably inserted in the outer surface of the vertical plate 75. A clamping plate 78 is fixedly connected to the end of the push rod 76 near the support plate 53. A tail plate 77 is fixedly connected to the end of the push rod 76 away from the clamping plate 78. A support 73 is set in the outer surface of the side plate 52. A rocker arm 74 is movably sleeved on the outer surface of the support 73. The top end of the rocker arm 74 is hinged to the lower surface of the tail plate 77. The other end of the rocker arm 74 is sleeved on the outer surface of the shaft 72. A spring 79 is fixedly connected to the outer surface of the slider 71. The end of the spring 79 away from the slider 71 is fixedly connected to the outer surface of the side plate 52.

[0025] During the process of the intelligent transfer machine 2's support plate 53 flipping from its initial upward tilted state to a horizontal state, the two sides of the support plate 53 simultaneously squeeze and push the symmetrically arranged sliders 71. The side of the slider 71 that abuts against the support plate 53 is precision-polished into a semi-circular arc shape, causing the slider 71 to slide away from the support plate 53 along the horizontal guide rail under the continuous push of the support plate 53. During the sliding process, the outer surface side of the slider 71 is rigidly connected to one end of the spring 79, synchronously stretching the spring 79 to generate elastic deformation and store elastic potential energy, providing power for subsequent reset. At the same time, the slider 71 moves away from the support plate 53. One end is fixed with a shaft 72 by a set screw. When the shaft 72 moves with the slider 71, it pushes the rocker arm 74 to rotate around the fixed support 73. The other end of the rocker arm 74 is movably connected to the tail plate 77. When the rocker arm 74 rotates, it drives the tail plate 77 to move synchronously, which in turn pushes the push rod 76 to slide along the guide sleeve, and finally drives the clamping plate 78 to move towards the middle of the support plate 53. The two symmetrically designed clamping plates 78 move synchronously towards each other, realizing the precise centering and calibration of the bag material on the support plate 53, ensuring that the bag material is always in the center of the conveying when it falls into the lower conveyor 3, effectively avoiding the bag material from being scratched and damaged by the edge of the lower conveyor 3.

[0026] Reference Figure 7 and Figure 8 As shown, the rolling assembly 8 includes a roller 81 rotatably connected inside the support plate 53. The outer surface of the roller 81 is provided with a ring array of strip grooves 82, and the inside of the strip grooves 82 is rotatably connected with balls 83.

[0027] After the goods land on the support plate 53, they fall onto the roller 81. The roller 81 has a ring-shaped groove 82 on its outer surface, and each groove is equipped with a ball bearing 83. The rotation direction of the ball bearing 83 is the same as the movement direction of the clamping plate 78. As a result, when the goods are pushed by the clamping plate 78, they will slide on the ball bearing 83. The rotation of the ball bearing 83 can reduce the friction during the movement of the goods, making it easier to center the goods. During the downward movement of the goods, the presence of the roller 81 can convert sliding friction into rolling friction, reduce friction, and ensure the smooth movement of the bagged goods.

[0028] Working Principle: In intelligent packaging equipment, when packaged bags need to be transferred from upper conveyor 1 to lower conveyor 3, a dedicated stable transfer system is required to achieve a damage-free connection. The bags first exit from upper conveyor 1 and fall into support plate 53. At this time, support plate 53 is aligned with the conveying surface of upper conveyor 1 and is in an initial upward tilted posture. Under the action of inertia, the bags slide along the inclined surface to the inner positioning area of ​​support plate 53. Then, rotating mechanism 44 drives center rod 43 to rotate and drives support assembly 5 to rotate 180 degrees synchronously, so that support plate 53 is aligned with lower conveyor 3. Then, hydraulic telescopic rod 42 pulls bracket 51 downward. During this process, spur gear 62 will contact rack column 63. Under the limiting action of column 63, spur gear 62 will rotate during the downward movement, which will drive worm 61 to rotate. During the rotation of worm 61, worm wheel 65 will be driven to rotate. Through worm wheel 65, turntable 64 will be driven to rotate slowly. During the rotation of turntable 64, lever 67 will be driven to make circular motion around the center of turntable 64, which will push hollow frame plate 66 to move upward. During the movement of hollow frame plate 66, it will pull connecting rod 69 through diagonal rod 2 610, forcing connecting rod 69 to slide along the horizontal slide of side plate 52. During the sliding of connecting rod 69, it will pull support plate 53 through diagonal rod 1 68, causing support plate 53 to flip downward around the axis connected to side plate 52. First, the support plate 53 flips from an upward tilted state to a horizontal state. During this process, the side of the support plate 53 presses against and pushes the slider 71. The side of the slider 71 that abuts against the support plate 53 is set in a semi-circular arc shape. Under the push of the support plate 53, the slider slides away from the support plate 53. At the same time, the slide plate stretches the spring 79, causing it to deform and store elastic potential energy. The shaft 72 fixed at the other end of the slider 71 pushes the rocker arm 74 during the sliding process, causing it to rotate around the support 73. Then, the other end of the rocker arm 74 pushes the tail plate 77, which in turn pushes the clamping plate 78 towards the center of the support plate 53 via the push rod 76. The clamping plate 78 then moves the goods on the support plate 53. The two symmetrically designed clamping plates 78 move relative to each other simultaneously, achieving precise centering and calibration of the bag material on the support plate 53. This ensures that the bag material is always in the center of the conveyor when it falls into the lower conveyor 3, effectively preventing the bag material from being scratched and damaged by the edge of the lower conveyor 3. After the goods fall onto the support plate 53, they fall onto the roller shaft 81. The annular groove 82 on the outer surface of the roller shaft 81 is equipped with balls 83. The rotation direction of the balls 83 is the same as the movement direction of the clamping plates 78. As a result, when the goods are pushed by the clamping plates 78, they will slide on the balls 83. The rotation of the balls 83 can significantly reduce frictional resistance, ensuring that the bag material moves smoothly without jamming, further improving the transfer efficiency and stability. As the support 51 continues to move downward, the spur gear 62 continues to rotate under the limit of the rack column 63, which will drive the support plate 53 to continue to flip downward. The support plate 53 will gradually pass over the slider 71. Under the action of the spring 79, the slider 71 will be reset. The swing of the rocker arm 74 will pull the clamping plate 78 away from the goods. In this way, the goods that have lost their clamping force will slide down along the support plate 53 under the action of gravity. And due to the presence of the roller shaft 81, the sliding friction can be converted into rolling friction, reducing the friction force. In this way, the intelligent transfer machine 2 can transfer the goods from the upper conveyor 1 to the lower conveyor 3. The intelligent transfer machine 2, through the coordination of mechanical transmission and hydraulic control, has a significantly smaller equipment footprint compared to the traditional slide, and greatly reduces the contact impact force between the bag and the equipment during the transfer process, effectively ensuring the integrity of the packaging bag during the transport process.
