Description

Technical Field

[0001] This utility model relates to the field of steel-edged strapping conveying machinery, and in particular to a conveying device for steel-edged strapping of packaging boxes. Background Technology

[0002] Steel-edged strapping is a strip material specifically designed for binding steel coils. It boasts high strength, capable of withstanding the weight of the steel coil and external forces; excellent wear resistance, making it resistant to wear during handling; strong corrosion resistance, adapting to various environments; and dimensional stability, ensuring consistent binding tightness. In the steel industry and related fields, it plays a crucial role in ensuring the safe transportation and storage of steel coils. When using steel coil strapping, the entire roll needs to be unwound. To unwound the strapping, the entire roll is placed on a spool, allowing the operator to pull out the beginning of the strapping.

[0003] Chinese invention patent application number 2024226086633 discloses a steel coil packing uncoiling device. Through the cooperation of the frame, rotating plate, support tube, fixing mechanism, conveying mechanism and resistance mechanism, it is easy to transport the packing strap smoothly and evenly. Even if the beginning end of the packing strap is loose, the packing strap will not be bounced back, which improves the safety of the operator. In the above device, the steel packing strap is wound on the power component. As the steel strap is consumed, the output speed of the steel strap changes. The output end of the packing strap passes through two sets of conveying wheels. When the packing strap is not used, the steel strap traction between the pressure wheel and the conveying wheel disappears, which can easily cause the steel strap to bend in the gap between the pressure wheel and the conveying wheel, affecting the efficiency of steel strap picking. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a conveying device for steel-edged packing straps of packaging boxes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conveying device for steel-edged packing straps of packaging boxes includes a base, an output mechanism, an anti-detachment structure, a support frame, a vertical electric push rod, a packing strap driving mechanism, and a guiding mechanism. The support frame is fixedly installed on the top of the base, and the vertical electric push rod is fixedly installed on the support frame. The output mechanism and the anti-detachment structure are rotatably installed on the side of the support frame. A packing strap roll is sleeved on the outer side of the output mechanism. The packing strap driving mechanism is fixedly installed at the bottom of the vertical electric push rod. The vertical electric push rod drives the packing strap driving mechanism to move downwards and press the packing strap roll tightly. The guiding mechanism is rotatably installed on the side of the packing strap driving mechanism, and the output end of the packing strap passes through the interior of the guiding mechanism.

[0007] Preferably, the output mechanism includes an output spindle rotatably connected to the support frame, and the middle part of the output spindle is a hollow structure. A bidirectional threaded screw is rotatably mounted in the middle part of the output spindle. Adjusting rings are screwed to the threaded portions at both ends of the bidirectional threaded screw. Three to five adjusting rods arranged in a ring array are rotatably mounted on the outer sides of the two adjusting rings. An arc-shaped mounting plate is hinged between the outer ends of two adjacent adjusting rods.

[0008] Preferably, the outer ends of the output spindle are provided with limiting grooves corresponding to the adjusting rods, and the middle of the outer side of the output spindle is provided with a guide groove between the two limiting grooves. The guide groove is perpendicular to the axis of the output spindle, and the bottom of the mounting plate is equipped with a guide rod that slides with the guide groove.

[0009] Preferably, the anti-detachment structure includes an anti-detachment motor mounted on a support frame, and a U-shaped swing rod is fixedly mounted on the outer side of the output end of the anti-detachment motor. Both inner walls of the swing rod are provided with strip grooves, and a pushing block is slidably mounted between the two strip grooves. An anti-detachment wheel that rolls with the outer side of the packing tape roll is mounted at the front end of the pushing block. A transverse electric push rod is mounted at the end of the swing rod, and the output shaft end of the transverse electric push rod is connected to the pushing block by a spring.

[0010] Preferably, the packing strap driving mechanism includes an L-shaped bracket installed at the bottom of a vertical electric push rod, and a spring rod is fixedly installed at the bottom of the L-shaped bracket. A pressure sensor is fixedly installed at the bottom of the spring rod, and a driving bracket is fixedly installed at the bottom of the pressure sensor. A driving roller is rotatably installed at the bottom of the driving bracket, and a driving motor for driving the driving roller to rotate is installed on the side of the driving bracket.

[0011] Preferably, the guiding mechanism includes a torsion spring shaft fixedly installed on the outer side of the L-shaped bracket, and an arc-shaped floating rod fixedly installed on the outer side of the torsion spring shaft. Two stop bars that limit the driving range of the floating rod are screwed onto the L-shaped bracket, and a guide sleeve is installed at the front end of the floating rod.

[0012] Preferably, the inlet end of the guide sleeve has a wedge-shaped structure, and the top and bottom of the guide sleeve are provided with through grooves, and the inside of the two through grooves is equipped with a V-shaped locking spring.

[0013] Compared with the prior art, this utility model provides a conveying device for steel-edged strapping of packaging boxes, which has the following advantages:

[0014] By using the output mechanism, when the bidirectional threaded screw is rotated clockwise, the adjusting rings at both ends of the bidirectional threaded screw move away from each other. Through the action of the adjusting rod, the mounting plates move towards the axis of the output main shaft. After the strapping roll is sleeved on the outside of multiple mounting plates, rotating the bidirectional threaded screw counterclockwise will cause multiple mounting plates to move outward synchronously, locking and fixing the strapping roll. When the strapping drive mechanism drives the strapping roll to rotate and output, under the action of centrifugal force, the mounting plates tend to expand outward, further improving the stability of the strapping roll fixation, thereby enhancing the stability and safety of the strapping conveyor.

[0015] With the anti-detachment structure in place, after the packing tape roll is fixed to the outside of the output mechanism, the anti-detachment motor drives the swing rod to rotate, and the packing tape roll is inserted into the opening of the swing rod. The inner wall of the swing rod constrains the edge of the packing tape roll, preventing the packing tape roll from shifting or loosening during rotation. In addition, the horizontal electric push rod drives the anti-detachment wheel to move towards the packing tape roll, pressing and fixing the side of the packing tape roll, further reducing the risk of the packing tape roll loosening and improving the stability and safety of the packing tape output.

[0016] Through the set guide mechanism, the output end of the strapping tape passes through the guide sleeve of the guide mechanism, which constrains and limits the output end of the strapping tape. At the same time, as the strapping tape is consumed and the output position changes, the floating rod is driven to swing around the torsion spring shaft, so as to prevent the output direction of the strapping tape from deviating from the driving direction of the strapping tape drive mechanism, thereby preventing the strapping tape from bending and improving the stability of the strapping tape output.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figure 1-8A conveying device for steel edge packing straps of packaging boxes includes a base 1, an output mechanism 2, an anti-detachment structure 3, a support frame 4, a vertical electric push rod 5, a packing strap driving mechanism 6, and a guiding mechanism 7. The support frame 4 is fixedly installed on the top of the base 1, and the vertical electric push rod 5 is fixedly installed on the support frame 4.

[0030] The output mechanism 2 and the anti-detachment structure 3 are both rotatably installed on the side of the support frame 4, and the rotation axes of the output mechanism 2 and the anti-detachment structure 3 are located at the same height. The outer side of the output mechanism 2 is fitted with a packing tape roll 8, and the anti-detachment structure 3 is distributed in an L-shaped structure, with one side of the packing tape roll 8 inserted into the interior of the anti-detachment structure 3.

[0031] Output mechanism 2 includes an output spindle 21 rotatably connected to support frame 4. The middle part of the output spindle 21 is hollow, and a bidirectional threaded screw 22 is rotatably mounted in the middle of the output spindle 21. Adjusting rings 23 are screwed to the threaded portions at both ends of the bidirectional threaded screw 22. Three to five adjusting rods 24 arranged in a ring array are rotatably mounted on the outer sides of the two adjusting rings 23. An arc-shaped mounting plate 25 is hinged between the outer ends of two adjacent adjusting rods 24. When the bidirectional threaded screw 22 is rotated clockwise, the adjusting rings 23 at both ends of the bidirectional threaded screw 22... The mounting plates 25 move towards the axis of the output main shaft 21 through the action of the adjusting rod 24. After the strapping roll 8 is sleeved on the outside of the multiple mounting plates 25, the double-threaded screw 22 is rotated counterclockwise to make the multiple mounting plates 25 move outward synchronously and lock and fix the strapping roll 8. When the strapping drive mechanism 6 drives the strapping roll 8 to rotate and output, the mounting plates 25 are in an outward expansion trend under the action of centrifugal force, which further improves the stability of the strapping roll 8 and thus enhances the stability and safety of the strapping conveyor.

[0032] Both ends of the outer side of the output spindle 21 are provided with limiting grooves 26 corresponding to the adjusting rods 24. A guide groove 27 is provided in the middle of the outer side of the output spindle 21 between the two limiting grooves 26. The guide groove 27 is perpendicular to the axis of the output spindle 21. A guide rod 28 is installed at the bottom of the mounting plate 25 and slides with the guide groove 27. During the opening and closing movement, the adjusting rod 24 is constrained by the limiting groove 26. When the mounting plate 25 expands and contracts, the guide rod 28 moves axially inside the guide groove 27, thereby constraining and guiding the movement trajectory of the mounting plate 25, maintaining the synchronicity and stability of the movement of multiple mounting plates 25, and further improving the stability and safety of fixing the packing tape roll 8.

[0033] The anti-detachment structure 3 includes an anti-detachment motor 31 mounted on a support frame 4. A U-shaped swing rod 32 is fixedly mounted on the outer side of the output end of the anti-detachment motor 31. Both inner walls of the swing rod 32 are provided with strip grooves 33. A pressing block 34 is slidably mounted between the two strip grooves 33. An anti-detachment wheel 35, which rolls with the outer side of the packing tape roll 8, is mounted at the front end of the pressing block 34. A transverse electric push rod 36 is mounted at the end of the swing rod 32, and the output shaft end of the transverse electric push rod 36 communicates with the pressing block 34 via... After the spring connection and the packing tape roll 8 is fixed to the outside of the output mechanism 2, the anti-detachment motor 31 drives the swing rod 32 to rotate, and the packing tape roll 8 is inserted into the opening of the swing rod 32. The inner wall of the swing rod 32 constrains the edge of the packing tape roll 8 to prevent the packing tape roll 8 from shifting and loosening during rotation. In addition, the horizontal electric push rod 36 drives the anti-detachment wheel 35 to move towards the packing tape roll 8, pressing and fixing the side of the packing tape roll 8, further reducing the risk of the packing tape roll 8 loosening and improving the stability and safety of the packing tape output.

[0034] The strapping drive mechanism 6 is fixedly installed at the bottom of the vertical electric push rod 5. The strapping drive mechanism 6 is located directly above the output mechanism 2. The vertical electric push rod 5 drives the strapping drive mechanism 6 to move downward and press the strapping roll 8 tightly. In turn, the strapping drive mechanism 6 drives the outer side of the strapping roll 8 to rotate, thereby providing stable output power to the strapping.

[0035] The strapping drive mechanism 6 includes an L-shaped bracket 61 installed at the bottom of the vertical electric push rod 5, a spring rod 62 fixedly installed at the bottom of the L-shaped bracket 61, a pressure sensor 63 fixedly installed at the bottom of the spring rod 62, a drive bracket 64 fixedly installed at the bottom of the pressure sensor 63, a drive roller 65 rotatably installed at the bottom of the drive bracket 64, and a drive motor 66 that drives the drive roller 65 to rotate is installed on the side of the drive bracket 64. After the strapping roll 8 is installed and fixed, the vertical electric push rod 5 drives the strapping drive mechanism 6 to move downward. The drive roller 65 is pressed tightly against the top of the strapping roll 8. When the drive roller 65 rotates, it drives the strapping roll 8 to be stably conveyed towards the guide mechanism 7. Through the signal feedback of the pressure sensor 63, the vertical electric push rod 5 is controlled to descend synchronously with the reduction of the outer diameter of the strapping roll 8, so as to maintain the stability of the conveying power.

[0036] The guide mechanism 7 is rotatably mounted on the side of the strapping drive mechanism 6, and the output end of the strapping passes through the interior of the guide mechanism 7, providing guidance and limiting for the output of the strapping;

[0037] The guiding mechanism 7 includes a torsion spring shaft 71 fixedly installed on the outer side of the L-shaped bracket 61, and an arc-shaped floating rod 73 fixedly installed on the outer side of the torsion spring shaft 71. Two stop rods 72 are screwed onto the L-shaped bracket 61 to limit the driving range of the floating rod 73. A guide sleeve 74 is installed at the front end of the floating rod 73. The output end of the packing strap passes through the guide sleeve 74 to constrain and limit the output end of the packing strap. At the same time, as the packing strap is consumed and the output position changes, the floating rod 73 is driven to swing around the torsion spring shaft 71 to prevent the output direction of the packing strap from deviating from the driving direction of the packing strap driving mechanism 6, thereby preventing the packing strap from bending and improving the stability of the packing strap output.

[0038] The inlet end of the guide sleeve 74 has a wedge-shaped structure, and the top and bottom of the guide sleeve 74 are provided with through grooves. The inside of the two through grooves is a V-shaped locking spring 75. When the strapping is output, it passes through the two locking springs 75. After the front end of the strapping is used up, the two locking springs 75 interlock with each other to lock the strapping inside the guide sleeve 74, preventing the strapping from shrinking backward.

[0039] Working principle: When the bidirectional threaded screw 22 is rotated clockwise, the adjusting rings 23 at both ends of the bidirectional threaded screw 22 move away from each other. Through the action of the adjusting rod 24, the mounting plate 25 is driven to move in the direction of the axis of the output main shaft 21. After the packing tape roll 8 is sleeved on the outside of multiple mounting plates 25, the bidirectional threaded screw 22 is rotated counterclockwise, which makes multiple mounting plates 25 move outward synchronously and lock and fix the packing tape roll 8. After the packing tape roll 8 is installed and fixed, the vertical electric push rod 5 drives the packing tape drive mechanism 6 to move downward. The drive roller 65 is pressed tightly against the top of the packing tape roll 8. When the packing tape drive mechanism 6 drives the packing tape roll 8 to rotate and output, the output end of the packing tape passes through the guide sleeve 74, which constrains and limits the output end of the packing tape. At the same time, as the packing tape is consumed and the output position changes, the floating rod 73 is driven to swing around the torsion spring shaft 71 to prevent the output direction of the packing tape from deviating from the driving direction of the packing tape drive mechanism 6, thereby preventing the packing tape from bending.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
