Description

Technical Field

[0001] This invention relates to the field of packaging box recycling technology, and more particularly to a device for recycling express packaging boxes. Background Technology

[0002] In recent years, the volume of express delivery business has been increasing year by year, leading to a surge in the number of paper express boxes. The existing method of recycling express boxes mostly involves manually collecting the boxes, disassembling them, and then sending them to recycling stations. This recycling method is inefficient and wastes a lot of human resources.

[0003] Chinese patent CN215704371U discloses a fully automatic packaging cardboard box recycling device, including a device housing. A first partition and a second partition are fixedly installed on the inner wall of the device housing. A squeezing plate is slidably installed on the top surface of the second partition. A squeezing cylinder is fixedly installed on the inner wall of the device housing, and one end of the squeezing cylinder is fixedly connected to one side of the squeezing plate. In this solution, the squeezing cylinder and squeezing plate can squeeze the cardboard box until it is flattened. Then, the squeezing cylinder retracts, and the cardboard box falls from a long trough and slides down into the collection box. Simultaneously, the two limiting cylinders are activated to confine the cardboard box in the middle. Then, the cutting cylinder is activated, and the cutting blade cuts the tape. The reduction motor is activated, driving the gear belt to rotate. After cutting, the packaging box is automatically fed into the next layer.

[0004] When opening the packaging box, the device uses a cutter to slice the tape sealing the hinges, but only slices the tape at the seam between the two hinges. However, the ends of the tape usually adhere to the sides of the box, meaning that even after slicing the tape at the hinge seam, the two hinges cannot be fully opened. This necessitates sending the box to a later process where the tape is manually or mechanically removed and the hinges opened before the box can be squeezed, folded, and recycled. Summary of the Invention

[0005] In view of this, the present invention proposes a recycling device for express packaging boxes, which solves the problem that the tape ends are usually stuck to the two sides of the packaging box, and the current recycling device only cuts the tape at the joint of the two hinges of the packaging box, so that even if the tape at the joint of the hinge is cut, the two hinges cannot be fully opened.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figure 1 As shown, combined with Figure 2 and Figure 8 The present invention provides a recycling device for express packaging boxes, comprising a platform 1, a positioning component 2, a heating component 3, and a cutting component 4.

[0031] The top of the packaging box 10 is open and the bottom hinge 11 is closed by tape 20, with the tape 20 extending at both ends and pasted on both sides of the packaging box 10.

[0032] Platform 1 is loaded with packaging boxes 10. A robotic arm and conveyor belt are set on one side of platform 1. The conveyor belt delivers the packaging boxes 10 to the workstation where this device is located in sequence. The robotic arm transfers the packaging boxes 10 to platform 1 through a suction cup mechanism, thereby achieving the purpose of intelligent and automated control of the entire production line.

[0033] Positioning component 2 is set on platform 1, and positioning component 2 positions the packaging box 10 on platform 1.

[0034] Heating component 3 is set on platform 1. Heating component 3 is close to the side of packaging box 10 and heats and softens the part of tape 20 that is pasted on the side of packaging box 10. Cutting component 4 is set on platform 1. Cutting component 4 cuts the tape 20 pasted at the seam of bottom hinge 11 of packaging box 10 from the inside of packaging box 10 and pushes bottom hinge 11 of packaging box 10 to open.

[0035] The principle of this invention is to first heat and soften the ends of the tape 20 on both sides of the packaging box 10 by heating the heating component 3, thereby weakening the adhesive force between the ends of the tape 20 and the sides of the packaging box 10. Then, the cutting component 4 cuts the tape 20 adhered to the bottom surface of the packaging box 10 at the joint of the hinge 11. The cutting component 4 continues to move forward and pushes the hinge 11 from the inside. Since the adhesive force between the ends of the tape 20 and the sides of the packaging box 10 has been weakened, the hinge 11 only needs to overcome the adhesive force between the two ends of the tape 20 and the edge of the bottom surface of the packaging box 10 when it is opened. Therefore, the hinge 11 can be opened easily without causing the packaging box 10 to be torn or deformed due to the large tearing force.

[0036] exist Figure 6 In a preferred embodiment shown, the cutter assembly 4 includes a tapered cutter 41.

[0037] Among them, window 101 is opened on platform 1.

[0038] Positioning component 2 positions and fixes the packaging box 10 above the window 101, so that the bottom surface of the packaging box 10 is exposed in the window 101.

[0039] The conical cutter 41 moves relative to the platform 1 and enters the packaging box 10 from the top. The tip of the conical cutter 41 abuts against the seam of the bottom hinge 11 of the packaging box 10 and cuts the tape 20 at the seam of the hinge 11. As the conical cutter 41 continues to move toward the window 101, since the conical cutter 41 is conical, it can be regarded as the tip of the conical cutter 41 being squeezed out from the seam of the hinge 11. As the conical cutter 41 gradually moves forward, the mating parts of the two hinges 11 are gradually pushed apart by the conical cutter 41, thereby opening the hinge 11.

[0040] exist Figure 7 In a preferred embodiment shown, the cutter assembly 4 further includes a base 42, a swing arm 43, and a movable part 44.

[0041] The base 42 is mounted on the platform 1 and located on one side of the window 101. A geared motor is installed inside the base 42 to control the rotation of the swing arm 43.

[0042] One end of the swing arm 43 is hinged to the base 42, and the other end of the swing arm 43 rotates around the base 42 via a horizontally extending pivot. The free end of the swing arm 43 rotates toward or away from the window 101.

[0043] The movable part 44 is hinged to the free end of the swing arm 43 and can rotate axially via a horizontally extending shaft. A tapered cutter 41 is provided on the movable part 44. A geared motor is also provided inside the movable part 44 to control the rotation angle of the movable part 44.

[0044] The conical cutter 41 rotates synchronously with the movable part 44. The conical cutter 41 moves relative to the movable part 44 in the direction perpendicular to the axis of rotation of the movable part 44, thereby gradually penetrating into the packaging box 10.

[0045] In this embodiment, the rotatable function of the swing arm 43 and the movable part 44 enables the conical cutter 41 to move in a direction perpendicular to the upper surface of the platform 1, thereby accurately cutting the joint of the hinge 11 and pushing the hinge 11 to open.

[0046] exist Figure 8 In a preferred embodiment shown, the cutter assembly 4 further includes a contouring portion 45.

[0047] The contouring part 45 is mounted on the movable part 44 and rotates synchronously with it. The contouring part 45 moves relative to the movable part 44 along the vertical direction of its axis of rotation. A cutting blade is mounted on the end face of the contouring part 45 away from the movable part 44. The outer contour of the contouring part 45 is the same as the inner contour of the packaging box 10 along the vertical direction of the platform 1 surface. The swing arm 43 drives the movable part 44 to rotate circumferentially around the base 42, and the movable part 44 drives the contouring part 45 to rotate axially, so that the end face of the contouring part 45 with the conical cutting blade 41 is parallel to the platform 1 surface, and the blade edge of the conical cutting blade 41 faces perpendicular to the platform 1 surface. The contouring part 45 is typically square, its function being twofold: firstly, to facilitate the opening of the hinge 11; and secondly, to prevent deformation during the cutting and pushing process by the conical cutting blade 41 when it enters the packaging box 10.

[0048] exist Figure 3 In a preferred embodiment shown, the heating component 3 includes a heating element 31.

[0049] Two heating elements 31 are symmetrically arranged on the platform 1 and located on both sides of the window 101. The two heating elements 31 are respectively aligned with the two sides of the adhesive tape 20 on the packaging box 10.

The heating elements 31 heat and soften the portion of the adhesive tape 20 that is attached to the side of the packaging box 10. A heat-conducting plate is provided at the front end of the heating element 31, and an electric heating wire is provided inside it.

[0050] exist Figure 3 In a preferred embodiment shown, the heating assembly 3 further includes a first drive mechanism 32, a first gear 33, and a first rack 34.

[0051] The first drive mechanism 32 is mounted on platform 1. The first drive mechanism 32 is a rotary motor.

[0052] The first gear 33 is connected to the output end of the first drive mechanism 32, and the first gear 33 rotates under the drive of the first drive mechanism 32.

[0053] The first rack 34 extends at both ends along the moving direction of the heating part 31. The heating part 31 is provided on the end of the first rack 34 facing the window 101. The first rack 34 cooperates with the first gear 33.

[0054] The first drive mechanism 32 drives the first gear 33 to rotate, and the rotation of the first gear 33 drives the first rack 34 to move back and forth, thereby causing the heating part 31 to approach or detach from the side of the packaging box 10.

[0055] exist Figure 3 In a preferred embodiment shown, the positioning component 2 includes a fixed plate 21, a movable plate 22, a first suction cup 23, and a second suction cup 24.

[0056] The fixed plate 21 and the movable part 44 are respectively disposed on the platform 1 and located on both sides of the window 101. The fixed plate 21 and the movable plate 22 are respectively disposed above the heating part 31.

[0057] The movable plate 22 moves horizontally relative to the platform 1, adjusting the distance between the movable plate 22 and the fixed plate 21. The moving trajectory of the movable plate 22 is diagonal, thus enabling it to adapt to packaging boxes 10 of different sizes.

[0058] The first suction cup 23 is mounted on the fixed plate 21 and located directly above the heating part 31.

[0059] The second suction cup 24 is disposed on the platform 1 and located between the fixed plate 21 and the movable part 44. The first suction cup 23 and the second suction cup 24 respectively adhere to two adjacent sides of the packaging box 10. The packaging box 10 is fixed by using two suction cups to avoid the problem of deformation of the packaging box 10 that may be caused by clamping.

[0060] exist Figure 4 In a preferred embodiment shown, the positioning component 2 further includes a tray 25.

[0061] The tray 25 is disposed on the upper surface of the platform 1 and located between the fixed plate 21 and the movable part 44. The tray 25 moves horizontally towards or away from the second suction cup 24 in the vertical direction of the moving direction of the heating part 31 and passes directly above the window 101. A notch 201 is provided on the tray 25, and the notch 201 connects with the window 101 when the tray 25 passes through the window 101. The tray 25 prevents the packaging box 10 from falling into the window 101.

[0062] exist Figure 5 In a preferred embodiment shown, the positioning component 2 further includes a limiting member 26.

[0063] The limiting member 26 is located on the edge of the tray 25 away from the second suction cup 24. The limiting member 26 rotates relative to the tray 25 and abuts against or releases the side of the packaging box 10 away from the second suction cup 24. When the limiting member 26 rotates to stand upright, as the tray 25 moves toward the second suction cup 24, the packaging box 10 is pushed by the limiting member 26 and sucked by the second suction cup 24. After the packaging box 10 is sucked, the limiting member 26 rotates to lie horizontally.

[0064] exist Figure 4 In a preferred embodiment shown, the positioning component 2 further includes a second drive mechanism 27, a second gear 28, and a second rack 29.

[0066] The second gear 28 is connected to the output end of the second drive mechanism 27, and the second gear 28 is driven by the second drive mechanism 27 to rotate the lower shaft.

[0067] The two ends of the second rack 29 extend along the moving direction of the support plate 25. The end of the second rack 29 facing the window 101 is connected to the support plate 25. The second rack 29 cooperates with the second gear 28.

[0068] The second drive mechanism 27 drives the second gear 28 to rotate, and the rotation of the second gear 28 drives the second rack 29 to move back and forth, thereby driving the pallet 25 to move the packaging box 10 on it back and forth.
