Description

Technical Field

[0001] This utility model relates to the field of detection and repair device technology, specifically a corrugated cardboard box damage detection and repair device. Background Technology

[0002] Corrugated cardboard boxes are packaging containers made from corrugated cardboard through processes such as die-cutting, creasing, nailing, or gluing. The core material, corrugated cardboard, is a multi-layered adhesive, usually consisting of at least one layer of corrugated core paper sandwiched between two layers of flat facing paper.

[0003] After the cardboard boxes are glued together, the glued joints of these flattened boxes need to be tested to determine the strength of the adhesion between the layers of corrugated cardboard. This ensures that the boxes will not delaminate or peel during use. If a glued joint fails the test, it is considered unqualified and needs to be picked out and re-glued. Moving unqualified boxes back and forth takes time and affects efficiency. We have proposed a corrugated cardboard box damage detection and repair device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a corrugated cardboard box damage detection and repair device to solve the problem of efficiency caused by back-and-forth movement mentioned in the background art.

[0006] An electric push rod is installed on the upper surface of the support plate, and a vacuum suction cup is installed at the output end of the electric push rod. An installation plate is connected inside the protective frame, and a vacuum suction cup is installed on the upper surface of the installation plate. An intermittent laser emitter is installed inside the protective frame, and a signal receiver is installed inside the protective frame.

[0007] The support plate is slidably connected to a connecting block, the connecting block is connected to a crossbar, the outer surface of the crossbar is rotatably connected to a nozzle, the connecting block is threadedly connected to a threaded rod, and the end of the threaded rod near the nozzle is connected to an extrusion plate.

[0008] A stepper motor is mounted on the outer surface of the support plate, and the output end of the stepper motor is connected to a threaded rod II. The outer surface of the threaded rod II is connected to the internal thread of the connecting block.

[0009] The outer surface of the threaded rod is rotatably connected to the inside of the support plate, and the outer surface of the nozzle is rotatably connected to the inside of the connecting block.

[0013] The transport pipe is installed inside the fixed block, and the outer surface of the nozzle is in contact with the outer surface of the extrusion plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model discloses a corrugated cardboard box damage detection and repair device. Through the cooperation between the intermittent laser emitter and the nozzle, the intermittent laser emitter first emits laser. If the laser is not obstructed, the cardboard box is qualified. If it is not qualified, the nozzle will spray glue on the cardboard box again to bond it.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides a corrugated cardboard box damage detection and repair device, which includes a support plate 1, a protective frame 2 connected to the bottom surface of the support plate 1, a conveyor belt 3 installed inside the protective frame 2, the protective frame 2 provides support for the support plate 1, the protective frame 2 restricts the position of the conveyor belt 3, a motor is installed inside the conveyor belt 3 to start the conveyor belt 3, and the cardboard box in a flat state is transported by the conveyor belt 3, and the glued part of the cardboard box is at the front end;

[0025] An electric push rod 4 is installed on the upper surface of the support plate 1. A vacuum suction cup 5 is installed at the output end of the electric push rod 4. The support plate 1 restricts the position of the electric push rod 4. When the electric push rod 4 is activated, the vacuum suction cup 5 can be activated, allowing the vacuum suction cup 5 to press against the upper surface of the cardboard box. The suction force of the vacuum suction cup 5 is greater than that of the vacuum suction cup 7.

[0026] The protective frame 2 has an internal mounting plate 6. A vacuum suction cup 7 is mounted on the upper surface of the mounting plate 6. The protective frame 2 fixes the position of the mounting plate 6, which restricts the position of the vacuum suction cup 7. The suction force of the vacuum suction cup 7 is adjustable. The vacuum suction cup is connected to a vacuum device (such as a vacuum generator) through a connecting pipe. The vacuum device is started to draw suction, creating negative pressure inside the suction cup, thereby adsorbing objects. By adjusting the pressure setting of the vacuum device, the suction force of the suction cup can be controlled. Usually, an appropriate pressure regulator is used to adjust to the recommended working pressure so that the suction force of the vacuum suction cup 7 can be adapted to the force that the paper box to be tested can withstand. When the electric push rod 4 raises the vacuum suction cup 5, if the paper box is qualified, it will be pulled off the vacuum suction cup 7. If it is unqualified, the glued parts of the paper box will be separated, thus testing the paper box.

[0027] An intermittent laser emitter 8 and a signal receiver 9 are installed inside the protective frame 2. The intermittent laser emitter 8 is activated after the electric push rod 4 lifts the vacuum suction cup 5. If the vacuum suction cup 5 moves the cardboard box upward, the laser emitted by the intermittent laser emitter 8 will directly irradiate the inside of the signal receiver 9. At this time, the cardboard box is qualified. If the glued part separates, the lower layer of the cardboard box will be sucked by the vacuum suction cup 7, which will block the laser and prevent the laser from shining into the signal receiver 9. At this time, the signal receiver 9 will alarm that the cardboard box is unqualified.

[0028] The support plate 1 has a sliding connection to a connecting block 10, and the connecting block 10 has a crossbar 11 connected inside. The support plate 1 prevents the connecting block 10 from rotating, and the connecting block 10 restricts the position of the crossbar 11.

[0029] A nozzle 12 is rotatably connected to the outer surface of the crossbar 11. A threaded rod 13 is threadedly connected to the inside of the connecting block 10. An extrusion plate 14 is connected to one end of the threaded rod 13 near the nozzle 12. The nozzle 12 can rotate around the crossbar 11 to adjust its orientation. Rotating the threaded rod 13 allows it to be installed inside the connecting block 10. Moving the threaded rod 13 will move the extrusion plate 14 with it.

[0030] A stepper motor 15 is mounted on the outer surface of the support plate 1. The output end of the stepper motor 15 is connected to a threaded rod 16. The outer surface of the threaded rod 16 is connected to the internal thread of the connecting block 10. The support plate 1 restricts the position of the stepper motor 15. When the stepper motor 15 starts, it will rotate the threaded rod 16. The rotation of the threaded rod 16 will move the connecting block 10.

[0031] The outer surface of the threaded rod 16 is rotatably connected to the inside of the support plate 1, and the outer surface of the nozzle 12 is rotatably connected to the inside of the connecting block 10. The support plate 1 restricts the vibration generated when the threaded rod 16 rotates, and the connecting block 10 restricts the position that the nozzle 12 can move. When the signal receiver 9 does not receive the laser signal, the stepper motor 15 will start to move the nozzle 12.

[0032] The nozzle 12 is connected to a transport pipe 17. The end of the transport pipe 17 away from the nozzle 12 is connected to a storage tank 18. The storage tank 18 is equipped with a pump for transporting glue. The pump can be remotely controlled to control the glue spraying time. The glue can be transported to the nozzle 12 through the transport pipe 17, so that the nozzle 12 can spray the glue onto the defective cardboard boxes.

[0033] A fixing block 19 is connected to the upper surface of the connecting block 10. The storage tank 18 is installed on the upper surface of the fixing block 19. When the connecting block 10 moves, the fixing block 19 will move with it, and when the fixing block 19 moves, the storage tank 18 will move with it.

[0034] The upper surface of the vacuum suction cup 5 contacts the bottom surface of the support plate 1, the inside of the threaded rod 13 is slidably connected to the outer surface of the crossbar 11, the outer surface of the extrusion plate 14 contacts the outer surface of the nozzle 12, the support plate 1 restricts the position that the vacuum suction cup 5 can move, and the threaded rod 13 restricts the end of the crossbar 11 from contacting the connecting block 10.

[0035] The transport pipe 17 is installed inside the fixed block 19. The outer surface of the nozzle 12 is in contact with the outer surface of the extrusion plate 14. The friction between the nozzle 12 and the contact surface of the connecting block 10 is increased by the extrusion plate 14 extruding the nozzle 12.

[0036] Working principle: When using this device, the conveyor belt 3 first sends the flat cardboard box to the bottom of the vacuum suction cup 5. Then, the electric push rod 4 is activated, causing the vacuum suction cup 5 to hold the upper layer of the cardboard box, and the vacuum suction cup 7 to hold the lower layer. The electric push rod 4 then raises the vacuum suction cup 5. Then, the intermittent laser emitter 8 is activated. If the laser shines on the signal receiver 9, the cardboard box is qualified. Then, the vacuum suction cup 5 releases the conveyor belt 3 and sends it away. If the laser does not shine on the signal receiver 9, the signal receiver 9 alarms, and the stepper motor 15 is activated, causing the threaded rod 16 to move the connecting block 10. The movement of the connecting block 10 will move the nozzle 12. At the same time, the glue in the storage tank 18 is delivered to the nozzle 12, and the nozzle 12 sprays the glue onto the opening of the cardboard box. Then, the electric push rod 4 lowers the vacuum suction cup 5 with the upper layer of the cardboard box, allowing the upper and lower layers of the cardboard box to be glued together again.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
