Description

Technical Field

[0001] This invention relates to the field of tape sealing technology, and in particular to a folding plate and tape sealing device for logistics cartons. Background Technology

[0002] With the rapid development of the e-commerce and logistics industries, cardboard boxes have become the most widely used containers in logistics packaging due to their advantages such as low cost, light weight, good cushioning performance, and recyclability. They are widely suitable for various logistics scenarios, including packing small items, repackaging large shipments, and warehousing and transshipment. After the goods are packed into boxes, the top flaps of the cardboard boxes must be bent and closed sequentially, and then the boxes must be sealed and secured with tape. This is the core process of logistics packaging.

[0003] Traditional carton sealing operations rely heavily on manual folding and sealing, resulting in high labor intensity, low efficiency, and inconsistent folding flatness and tape adhesion. While existing tape sealing equipment can automate sealing, it generally lacks a matching automatic folding structure. Before sealing, manual bending of the carton panels is still required to complete the capping, making the process cumbersome and severely limiting the overall efficiency of cardboard packaging. This makes it difficult to meet the demands of modern logistics for large-scale, automated, and high-efficiency packaging. Summary of the Invention

[0004] The purpose of this invention is to provide a folding and tape sealing device for logistics cartons, so as to solve the problems and defects mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a folding plate and tape sealing device for logistics cartons, comprising a hollow base, a bracket fixedly installed on the top of the hollow base, a first electric push rod fixedly installed on the top of the bracket, a lifting arm fixedly installed on the free end of the first electric push rod, a guide groove opened on the top of the hollow base, a guide block slidably installed in the guide groove, and a telescopic rod assembly disposed on the guide block, wherein a folding plate assembly is installed on the hollow base and the telescopic rod assembly.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0019] Please see Figure 1-3 The present invention provides a technical solution: a folding plate and tape sealing device for logistics cartons, including a hollow base 1, a bracket 2 fixedly installed on the top of the hollow base 1, a first electric push rod 3 fixedly installed on the top of the bracket 2, a lifting arm 4 fixedly installed on the free end of the first electric push rod 3, a guide groove 12 opened on the top of the hollow base 1, a guide block 24 slidably installed in the guide groove 12, and a telescopic rod assembly set on the guide block 24. A folding plate assembly is installed on the hollow base 1 and the telescopic rod assembly.

[0020] Furthermore, the folding assembly includes a motor 19, a rotating shaft 20, and a turntable 21. The motor 19 is fixedly installed on the bottom outer wall of the hollow base 1, the rotating shaft 20 is rotatably installed on the top and bottom of the hollow base 1, and the turntable 21 is fixedly installed on the outer wall of the rotating shaft 20. The output shaft of the motor 19 is fixedly installed on one end of the rotating shaft 20. The hollow base 1, guide block 24, folding assembly, and telescopic rod group are used to fold the carton. The unfolding belt structure set on the lifting arm 4 is used to seal the carton through the first electric push rod 3, lifting arm 4, and unfolding belt structure. The motor 19 is a stepper motor, which can precisely control the rotation angle of the turntable 21 and the rhythm of the folding action, ensuring accurate folding sequence and moderate force.

[0021] Furthermore, the telescopic rod assembly includes a hollow rod 13, a bending rod 14, a telescopic rod 15, and a folding plate 16. The hollow rod 13 is fixedly installed on the guide block 24, the bending rod 14 is slidably installed on the inner side of the hollow rod 13, the telescopic rod 15 is slidably installed on the inner side of the bending rod 14, and the folding plate 16 is fixedly installed on one end of the telescopic rod 15. The folding plate 16 is made of a flexible and wear-resistant material, which does not scratch the surface of the carton during bending, and at the same time ensures that the cover plate is bent in place without springback.

[0022] Furthermore, the conveyor belt structure includes a slider 5, a tape roller 6, a rubber pressure roller 8, a toothed clamping roller 9, and a third electric push rod 25. The bottom of the lifting arm 4 is provided with a sliding groove, and the slider 5 is slidably installed in the sliding groove. The third electric push rod 25 is fixedly installed on the rear side of the sliding groove, and the free end of the third electric push rod 25 is fixedly installed on the rear side of the slider 5. The tape roller 6, the rubber pressure roller 8, and the toothed clamping roller 9 are all rotatably installed on the slider 5. The tape 7 is sleeved on the tape roller 6, and one end of the tape 7 is located between the rubber pressure roller 8 and the toothed clamping roller 9. The toothed clamping roller 9 can prevent the tape from slipping and shifting during the conveying process, and the rubber pressure roller 8 can tightly press the tape onto the surface of the carton to avoid the generation of air bubbles and wrinkles.

[0023] Furthermore, the turntable 21 has a push-pull groove 22, and the hollow rod 13 is movably installed in the push-pull groove 22. The push-pull groove 22 is an arc-shaped gradient groove, which can drive the hollow rod 13 to achieve uniform and stable radial movement, ensuring that the four sets of folding plates move synchronously and in coordination.

[0024] Furthermore, a first bolt 17 is threaded on one side of the hollow rod 13, one end of which contacts the bending rod 14. A second bolt 18 is threaded on the top of the bending rod 14, one end of which contacts the telescopic rod 15. The first bolt 17 and the second bolt are an adjustable rod assembly, which improves the efficiency of equipment adjustment to adapt to different sizes of cartons.

[0025] Furthermore, the guide groove 12, hollow rod 13, bending rod 14, telescopic rod 15, folding cardboard 16, first bolt 17, second bolt 18, push-pull groove 22, and guide block 24 are all arranged in four sets in a circular array. The four sets of structures are symmetrically distributed, which can bend the four cover plates of the carton in sequence. After closing, the carton opening is flat and tight, which meets the sealing requirements of subsequent carton sealing.

[0026] Furthermore, the lifting arm 4 is fixedly installed with a second electric push rod 10, and a cutting blade 11 is fixedly installed at the free end of the second electric push rod 10. The cutting blade 11 is a serrated blade that can quickly cut the tape and make a neat cut.

[0027] Working principle: Before operation, adjust the relative positions of the hollow rod 13, bending rod 14 and telescopic rod 15, and lock them with the first bolt 17 and the second bolt 18. Adjust the folding paperboard 16 to the working position that matches the size of the carton. Place the carton on top of the hollow base 1. Start the motor 19 through the control panel 23. The motor 19 drives the rotating shaft 20 and the turntable 21 to rotate. The push-pull groove 22 on the turntable 21 pushes the hollow rod 13 and the guide block 24 to move along the guide groove 12, so that the four sets of folding paperboard 16 complete the bending and closing of the carton cover in sequence. After the folding is completed, the first electric push rod 3 drives the lifting arm 4 to descend, so that the tape 7 adheres to the top surface of the carton. The third electric push rod 25 pushes the slider 5 to move along the slide groove, the tape roller 6 releases the tape, and the rubber pressure roller 8 and the toothed clamping roller 9 cooperate to press and stick the tape 7. After the carton is sealed, the second electric push rod 10 drives the cutting blade 11 to move down and cut the tape, completing the fully automated operation of folding and sealing.

[0028] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
