Description

Technical Field

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

[0002] Rapid packaging machines primarily utilize a motor to drive gears, belts, and other transmission devices, causing the packaging straps to tighten around items or boxes and be heat-sealed for secure fixation. Their applications are wide-ranging, encompassing product packaging and raw material handling in industrial production, cargo reinforcement and containerization in logistics transportation, and packaging of household items.

[0003] A Chinese utility model patent with authorization announcement number CN215554403U discloses a speed-up and straightening device for a PE strapping machine, including an integral moving plate, a first straightening component, and a second straightening component. The integral moving plate is in the shape of an inverted U and is located at the bottom of the machine frame. The first straightening component is installed at the bottom of the vertical end on one side of the integral moving plate, and the second straightening component is installed at the bottom of the vertical end on the other side of the integral moving plate. An adjusting screw is installed on one side of the horizontal end of the integral moving plate, and a moving support rod is installed on each of the left and right sides of the adjusting screw. A moving auxiliary support rod is installed on the other side of the horizontal end of the integral moving plate.

[0004] In traditional automated packaging processes, after products fall onto the conveyor belt from the previous stage, the boxes containing the products often deviate from the center line of the conveyor belt. Existing straightening devices can generally only meet the straightening needs of boxes of a single size within the same batch. However, when switching to another batch of boxes of different sizes, they cannot achieve accurate correction, thus limiting their application range. Utility Model Content

[0005] The purpose of this invention is to provide a straightening device for a rapid packing machine, which can achieve the straightening and switching of boxes of different sizes, has strong adaptability and stable straightening effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a straightening device for a rapid packaging machine, including a conveyor table, a conveying mechanism on the conveyor table, and straightening mechanisms arranged opposite to each other on two sides of the conveying mechanism. The straightening mechanism includes two straightening plates, and a reciprocating mechanism is arranged at the bottom of the conveyor table. The reciprocating mechanism drives the two straightening plates to move closer or further apart from each other. A telescopic member is arranged on the reciprocating mechanism, and the telescopic member adjusts the distance between the straightening plates and the reciprocating mechanism.

[0007] By adopting the above technical solution, the device drives the two straightening plates on both sides to achieve relative displacement of moving closer or further apart through the reciprocating mechanism. When they move closer, the device can apply a lateral thrust to the tilted or deviated box to correct its position and bring it back to the center line. When they move further apart, the device makes room for the next box to enter or be adjusted. At the same time, the telescopic component adjusts the distance between the straightening plate and the reciprocating mechanism, thereby changing the working range of the two straightening plates and achieving the effect of switching between straightening boxes of different sizes.

[0008] A further feature of this invention is that the telescopic component includes a telescopic rod, an insert rod, and a limiting plate. The telescopic rod is vertically connected to the straightening plate. The telescopic rod has several insertion holes, and the limiting plate has two insertion holes. The insert rod moves through the two insertion holes and is inserted into the insertion hole.

[0009] By adopting the above technical solution, the telescopic rod is vertically connected to the straightening plate. After the insertion hole one on the telescopic rod is aligned with the insertion hole two on the limiting plate, it is fixed by insertion. Different insertion holes one can be selected to change the telescopic length, thereby adjusting the spacing of the straightening plates and achieving stable straightening of boxes of different sizes.

[0010] A further feature of this invention is that the reciprocating mechanism includes a sliding mechanism and a rotary mechanism. The sliding mechanism includes a linear guide rail, a sliding component, and a drive shaft. The linear guide rail is fixedly connected to the conveyor table. The sliding component is slidably connected to the linear guide rail. The drive shaft is rotatably connected to the linear guide rail. The rotary mechanism controls the reciprocating motion of the drive shaft.

[0011] A further feature of this invention is that the sliding assembly includes two drive rods, a swing rod, and a slide rod. The ends of the two drive rods are respectively radially fixed on both sides of the drive shaft. The swing rod is hinged to the end of the drive rod away from the drive shaft. The slide rod is hinged to the end of the swing rod away from the drive rod. The slide rod is fixedly connected to the limiting plate.

[0012] By adopting the above technical solution, in the sliding assembly, the drive rods on both sides of the drive shaft rotate with the shaft, and drive the swing rod to swing through the hinge with the swing rod, thereby pulling or pushing the slide rod that is hinged with it. The linear guide rail is fixed to the conveyor table. Under the guidance of the linear guide rail, the swing of the swing rod and the rotation of the drive rod are smoothly converted into the linear motion of the slide rod. Since the slide rod is fixedly connected to the limiting plate, the driving force can be transmitted to the limiting plate in sequence through the drive rod, the swing rod, and the slide rod, thereby driving the limiting plate and the straightening plate associated with the limiting plate to adjust their positions along the linear direction, realizing the movement of the straightening plate closer to or further away.

[0013] A further feature of this invention is that the rotary mechanism includes a rotary shaft, a support platform, a toggle member, and two rotary drums. The rotary shaft is coaxially arranged with the drive shaft. The two rotary drums are axially fixed on both sides of the rotary shaft. The rotary drums are fixedly connected to the drive shaft. The support platform is fixedly arranged at the bottom of the conveyor platform. The rotary drums are rotatably connected to the support platform. The toggle member controls the reciprocating motion of the rotary drums and the drive shaft.

[0014] A further feature of this invention is that the actuating component includes a drive motor, a lever, and a turntable. The lever actuates the rotary drum. The lever is evenly distributed on the circumferential edge of the turntable end face. The turntable is located on one side of the rotary drum. The drive motor is located on the side of the turntable away from the rotary drum. The output end of the drive motor is coaxially and fixedly connected to the turntable. A second support platform is provided at the bottom of the conveyor table, and the drive motor is fixedly mounted on the second support platform.

[0015] By adopting the above technical solution, the drive motor is fixed to the second support platform, and its output end drives the turntable to rotate, so that the lever on the edge of the turntable moves with the circumference of the turntable, and sequentially moves the rotary cylinders on both sides of the rotary shaft. Since the rotary cylinders are fixed to the drive shaft and rotatably connected to the first support platform, the drive shaft moves back and forth with the rotary cylinders under the alternating movement of the levers, thereby providing stable reciprocating power for the sliding mechanism and ensuring the continuity and accuracy of the adjustment of the straightening plate spacing.

[0016] A further feature of this invention is that the rotation angle of the drive shaft is less than 180 degrees.

[0017] By adopting the above technical solution, this angle limitation can prevent the rocker arm in the sliding component from colliding with the drive shaft, which not only ensures that the rotary mechanism can rotate continuously and stably, but also provides reliable power for the sliding component of the reciprocating mechanism, ensuring the continuous adjustment of the spacing of the straightening plate.

[0018] A further feature of this invention is that visual sensors are provided on both the front and rear sides of the conveyor platform.

[0019] By adopting the above technical solution, the visual sensors set on the front and rear sides of the conveyor can detect in real time whether the box is tilted or deviates from the center line. Once an abnormality is detected, the straightening process is initiated. At the same time, the front and rear side settings can avoid the box from obstructing the view, ensuring the comprehensiveness and accuracy of the detection.

[0020] A further feature of this invention is that the conveying mechanism includes a conveyor belt, a conveyor motor, and a support platform. The conveyor belt is disposed above the inner part of the conveyor platform, the support platform is located on one side of the conveyor belt, and the conveyor motor is fixedly disposed on the support platform. The conveyor motor controls the movement of the conveyor belt.

[0021] By adopting the above technical solution, the conveyor motor controls the movement of the conveyor belt, first transporting the boxes to the inspection area, driving the boxes to move synchronously, and then transporting the uprighted boxes to the packing machine for packing, realizing a continuous process of box conveying, uprighting to packing.

[0022] The beneficial effects of this utility model are:

[0023] 1. This device uses a reciprocating mechanism to drive the two straightening plates on both sides to achieve relative displacement of moving closer or further apart. When they move closer, they can apply a lateral thrust to the tilted or off-center box to correct its position and bring it back to the center line. When they move further apart, they leave space for the next box to enter or be adjusted. At the same time, the telescopic component adjusts the distance between the straightening plate and the reciprocating mechanism, thereby changing the working range of the two straightening plates and achieving the effect of switching between straightening boxes of different sizes.

[0024] 2. The telescopic rod is vertically connected to the straightening plate. After the first insertion hole on the telescopic rod is aligned with the second insertion hole on the limiting plate, it is fixed by insertion. Different insertion holes can be selected to change the telescopic length, thereby adjusting the spacing of the straightening plates and achieving stable straightening of boxes of different sizes.

[0025] 3. The drive motor is fixed to the second support platform. Its output end drives the turntable to rotate, causing the levers on the edge of the turntable to move in a circular motion with the turntable. They sequentially move the rotary cylinders on both sides of the rotary shaft. Since the rotary cylinders are fixed to the drive shaft and rotatably connected to the first support platform, the drive shaft reciprocates with the rotary cylinders under the alternating movement of the levers. This provides stable reciprocating power for the sliding mechanism, ensuring the continuity and accuracy of the adjustment of the straightening plate spacing.

[0026] 4. In the sliding assembly, the drive rods on both sides of the drive shaft rotate with the shaft. Through the hinge with the swing rod, the swing rod swings, which in turn pulls or pushes the slide rod that is hinged to it. The linear guide rail is fixed to the conveyor table. Under the guidance of the linear guide rail, the swing of the swing rod and the rotation of the drive rod are smoothly converted into the linear motion of the slide rod. Since the slide rod is fixedly connected to the limiting plate, the driving force can be transmitted to the limiting plate in sequence through the drive rod, the swing rod, and the slide rod. This causes the limiting plate and the straightening plate associated with the limiting plate to adjust their positions along a straight line, thus realizing the movement of the straightening plate closer to or further away from the limiting plate.

[0034] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] like Figure 1-4 As shown, a straightening device for a rapid packing machine includes a conveyor table 1, a conveying mechanism 2 on the conveyor table 1, and straightening mechanisms on both sides of the conveying mechanism 2. Each straightening mechanism includes two straightening plates 3. A reciprocating mechanism 4 is provided at the bottom of the conveyor table 1. The reciprocating mechanism 4 drives the two straightening plates 3 to move closer or further apart. A telescopic component 5 is provided on the reciprocating mechanism 4 to adjust the distance between the straightening plates 3 and the reciprocating mechanism 4. When the reciprocating mechanism 4 is running, it drives the two straightening plates 3 to sometimes move closer together, pushing the boxes on the conveyor belt 21 to the center position; and sometimes move further apart, making room for the next box to enter or its position to be adjusted. At the same time, the telescopic component 5 adjusts the distance between the straightening plates 3 and the reciprocating mechanism 4, thereby changing the working range of the two straightening plates 3 and achieving the effect of switching between straightening boxes of different sizes.

[0036] The telescopic component 5 includes a telescopic rod 51, an insert rod 52, and a limiting plate 53. The telescopic rod 51 is vertically connected to the straightening plate 3. The telescopic rod 51 is provided with several insertion holes 54, and the limiting plate 53 is provided with insertion holes 55. The insert rod 52 moves through the insertion hole 55 and is inserted into the insertion hole 54. The telescopic rod 51 is vertically connected to the straightening plate 3. During operation, by selecting different positions of the insertion holes 54 on the telescopic rod 51 and aligning them with the insertion holes 55 on the limiting plate 53, the insert rod 52 is inserted and fixed, thereby changing the effective length of the telescopic rod 51 and adjusting the distance between the two straightening plates 3, so as to achieve stable straightening of boxes of different sizes.

[0037] The reciprocating mechanism 4 includes a sliding mechanism 6 and a rotary mechanism 7. The sliding mechanism 6 includes a linear guide rail 8, a sliding assembly 9, and a drive shaft 10. The linear guide rail 8 is fixedly connected to the conveyor table 1. The sliding assembly 9 is slidably connected to the linear guide rail 8. The drive shaft 10 is rotatably connected to the linear guide rail 8. The rotary mechanism 7 controls the reciprocating motion of the drive shaft 10. The sliding assembly 9 includes two drive rods 91, a rocker arm 92, and a sliding rod 93. The ends of the two drive rods 91 are radially fixed on both sides of the drive shaft 10. The rocker arm 92 is located away from the drive rods 91. The sliding rod 93 is hinged to the end of the swing rod 92 away from the drive rod 91, and the sliding rod 93 is fixedly connected to the limiting plate 53. In the sliding assembly 9, the drive shaft 10 rotates and drives the drive rods 91 on both sides to rotate synchronously. By pulling or pushing the swing rod 92 through the hinge point with the swing rod 92, the sliding rod 93 moves linearly under the guidance of the linear guide rail 8. Since the sliding rod 93 is fixedly connected to the limiting plate 53, it drives the limiting plate 53 and the straightening plate 3 associated with the limiting plate 53 to adjust their positions along the linear direction, so as to move the straightening plate 3 closer to or further away from the driving rod 92.

[0038] The rotary mechanism 7 includes a rotary shaft 11, a support platform 12, a toggle element 13, and two rotary drums 14. The rotary shaft 11 is coaxially arranged with the drive shaft 10. The two rotary drums 14 are axially fixed on both sides of the rotary shaft 11 and are fixedly connected to the drive shaft 10. The support platform 12 is fixedly arranged at the bottom of the conveyor platform 1, and the rotary drums 14 are rotatably connected to the support platform 12. The toggle element 13 controls the reciprocating motion of the rotary drums 14 and the drive shaft 10. The toggle element 13 includes a drive motor 131, a lever 132, and a turntable 133. The lever 132 toggle the rotary drums 14 to rotate. The levers 132 are evenly arranged on the circumferential edge of the end face of the turntable 133. The turntable 133 is located on one side of the rotary drum 14 and is away from the rotary drum 14. A drive motor 131 is provided on one side of the 4. The output end of the drive motor 131 is coaxially and fixedly connected to the turntable 133. A support platform 134 is provided at the bottom of the conveyor 1. The drive motor 131 is fixedly mounted on the support platform 134. The rotation angle of the drive shaft 10 is less than 180 degrees. The two rotary drums 14 are the upper rotary drum 14 and the lower rotary drum 14, respectively. The output end of the drive motor 131 drives the turntable 133 to rotate. The lever 132 fixedly connected to the edge of the turntable 133 moves with the circumference of the turntable 133 and sequentially moves the rotary drums 14 on both sides of the rotary shaft 11. Under the alternating movement of the lever 132, the drive shaft 10 reciprocates with the rotary drums 14, so that the sliding mechanism 6 moves back and forth stably, and the spacing between the straightening plates 3 is close to or far away from each other.

[0039] Visual sensors 15 are installed on the front and rear sides of the conveyor 1. When the box is transported to the detection area, the visual sensors 15 fixed on the front and rear sides of the conveyor 1 monitor the status of the box in real time. If tilting or deviation from the center line is detected, the drive motor 131 is immediately triggered to start the straightening process.

[0040] The conveying mechanism 2 includes a conveyor belt 21, a conveyor motor 22, and a support platform 3 23. The conveyor belt 21 is located on the inner upper part of the conveyor platform 1, and the support platform 3 23 is located on one side of the conveyor belt 21. The conveyor motor 22 is fixedly mounted on the support platform 3 23 and controls the movement of the conveyor belt 21. The conveyor motor 22 controls the relative movement of the conveyor belt 21 on the conveyor platform 1, first conveying the boxes to the inspection area, driving the boxes to move synchronously, and then transporting the uprighted boxes to the packing machine for packing, realizing a continuous process from conveying, uprighting to packing of the boxes.

[0041] The working process of the straightening device for a rapid packaging machine according to this utility model is as follows:

[0042] S1. Start the conveyor motor 22 to make the conveyor belt 21 run. When the box is transported to the detection area, the vision sensors 15 on the front and rear sides of the conveyor table 1 monitor the status of the box in real time. If tilting or deviation from the center line is detected, the drive motor 131 is immediately triggered to start the straightening process.

[0043] S2. From the front view, the drive motor 131 drives the turntable 133 to rotate counterclockwise. When the edge lever 132 of the turntable 133 contacts the upper rotary drum 14, the drive shaft 10 rotates clockwise (the angle is less than 180 degrees), causing the swing arms 92 on both sides to swing towards the drive shaft 10. The swing arms 92 drive the slide rod 93 to retract inward. The slide rod 93 pushes the limit plate 53, and then the telescopic rod 51 drives the straightening plate 3 to move closer to each other on the conveyor table 1, thus correcting the box to the center position of the conveyor belt 21.

[0044] S3. When the lever 132 continues to rotate with the turntable 133 until it contacts the lower rotary drum 14, the drive shaft 10 rotates counterclockwise, and the swing arms 92 on both sides swing away from the drive shaft 10. The swing arms 92 drive the slide bar 93 to move outward, and the slide bar 93 drives the limit plate 53, and then the telescopic rod 51 drives the straightening plate 3 to move away from the conveyor table 1 and reset synchronously, completing a single straightening cycle, and waiting for the next box to enter the detection area.

[0045] S4. When it is necessary to straighten the next batch of boxes of different sizes, pull out the plug 52 between the telescopic rod 51 and the limiting plate 53, move the telescopic rod 51 inward or outward to the target position, and then move the plug 52 through the second plug hole 55 and insert it into the appropriate first plug hole 54 to relock the position. This will change the initial distance and maximum stroke of the straightening plates 3 on both sides to adapt to the straightening needs of boxes of different sizes.
