Description

Technical Field

[0001] This invention relates to the field of logistics and transportation technology, specifically to an automatic packaging device for logistics and transportation. Background Technology

[0002] Logistics and transportation technology mainly includes two categories: transportation facilities and transportation operations. The former belongs to hard transportation technology, while the latter belongs to soft transportation technology. Hard transportation technology mainly includes the improvement of transportation infrastructure, such as highways, railways, shipping, and transport vehicles. Soft transportation technology includes management methods, logistics technology, and the quality of logistics personnel. Packaging and handling of express delivery is required during the logistics and transportation process. Chinese patent CN 218839963 U discloses a packaging device for logistics transportation. This packaging device transports packaging boxes through a conveyor. When the packaging box is transported to the position of the folding mechanism, the folding mechanism presses the packaging box shut. Then, the end of the tape adheres to the side wall of the packaging box. As the packaging box continues to move forward, the tape automatically seals the packaging box, thus realizing the packaging of express delivery. It eliminates the need for staff to pack express delivery and can continuously pack express delivery. The packaging efficiency is high and it is suitable for application in logistics fields with a large number of express delivery packages. However, the aforementioned packaging device for logistics transportation uses pressure rollers to hold the tape in place, thus ensuring the sealing effect of the tape on the packaging box. But in actual use, in order to ensure the sealing effect of the packaging box, the two ends of the tape stuck to the top will be longer than the length of the packaging box. Then the two ends of the tape will stick to the side of the packaging box. However, a single pressure roller located above cannot press down on the two ends of the tape to achieve the purpose of sticking the two ends of the tape to the side of the packaging box. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic packaging device for logistics transportation to solve the problems mentioned in the background art.

[0013] According to the above technical solution, there are two electric telescopic rods, which are located on the front and back of the outer shell respectively, and a ball bearing is fixedly installed on the outer wall of the clamping plate away from the connecting plate.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. In this invention, when the left side of the packaging box moves to the position of the first pressure roller, the second electric telescopic rod drives the hollow plate to move down, which in turn drives the first fixing frame to move down, so that the bottom of the first pressure roller contacts the top of the tape, pressing the tape and making the tape adhere more tightly to the packaging box. When the left side of the packaging box moves to the position of the second pressure roller, the second electric telescopic rod drives the hollow plate to move down, which in turn drives the first and second fixing frames to move down, so that the first and second pressure rollers move down from the position at the top of the packaging box to the position on the side of the packaging box. The moving first and second pressure rollers press the two ends of the tape onto the side of the packaging box to complete the sealing. 2. In this invention, a high-speed airflow is generated by a fan. The airflow flows through the air pipe and the hollow plate in sequence. Part of the airflow enters the nozzle and blows it to the right and downward towards the tape on the adhesive device, causing the tape to be blown to the right and downward so that the tape can be better adhered to the packaging box. The other part enters the hollow plate through the corrugated pipe and then blows it to the tape through the vent hole, so that the airflow blows the tape from top to bottom, making the tape firmly adhered to the packaging box. 3. In this invention, the lead screw is rotated according to the height of the packaging box. The rotation of the lead screw causes the guide plate to move up and down, so that the bottom surface of the roller just contacts the top of the packaging box. The top layer of the packaging box is placed and its raised edge is pressed down little by little along the raised edge of the guide plate, so that the top layer of the packaging box is flat. 4. In this invention, a first electric telescopic rod drives the insulating cylinder to move, which in turn drives the insulating plate to move. The movement of the insulating plate drives the spring to move, which in turn drives the baffle to move. The movement of the baffle drives the push rod to move, which in turn drives the connecting plate to move. The movement of the connecting plate drives the clamping plate to move and limit the clamping of the packaging box. When the first electric telescopic rod continues to drive the insulating cylinder to move, the connecting plate is forced to push the push rod to move, which in turn blocks the movement of the baffle. At this time, the insulating plate is driven to continue to move, which in turn drives the first conductive piece to move. When the first conductive piece contacts the second conductive piece, the first electric telescopic rod is de-energized and no longer drives the insulating cylinder to move. This avoids excessive force between the clamping plate and the packaging box, which would prevent the packaging box from being transported by the roller conveyor. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0018] A preferred embodiment of the automatic packaging device for logistics transportation provided by the present invention is as follows: Figures 1 to 9 As shown: An automatic packaging device for logistics transportation includes a roller conveyor 1 and a housing 2. A packaging box 10 is disposed in contact with the top of the roller conveyor 1, and adhesive tape 17 is adhered to the top of the packaging box 10. A pressing mechanism 6 is fixedly installed inside the housing 2. The pressing mechanism 6 includes a second electric telescopic rod 601. The top of the second electric telescopic rod 601 is fixedly connected to the inner wall of the outer casing 2. A hollow plate 602 is fixedly installed at the bottom of the second electric telescopic rod 601. A first fixing frame 603 is fixedly installed at the right end of the hollow plate 602. A first pressure roller 604 is fixedly installed inside the first fixing frame 603. A second fixing frame 606 is fixedly installed at the left end of the hollow plate 602. A second pressure roller 605 is fixedly installed inside the second fixing frame 606. The second pressure roller 605 and the first pressure roller 604 are located on the left and right sides of the packaging box 10, respectively. The lower surface of the hollow plate 602... Contacting the upper surface of the tape 17, the bottom and sides of the first pressure roller 604 and the second pressure roller 605 extend to the outside of the first fixing frame 603 and the second fixing frame 606, respectively. The second electric telescopic rod 601 drives the hollow plate 602 to move up and down. The first fixing frame 603 and the second fixing frame 606 are set so that the up and down movement of the hollow plate 602 can synchronously drive the first pressure roller 604 and the second pressure roller 605 to move up and down. The first pressure roller 604 and the second pressure roller 605 simultaneously press the two ends of the tape 17 on the top of the packaging box 10 so that the two ends of the tape 17 are stuck to the two sides of the packaging box 10. A blower mechanism 3 is fixedly installed on the top of the outer casing 2, a guide mechanism 4 is fixedly installed inside the outer casing 2, and a clamping mechanism 5 is fixedly installed on the side of the outer casing 2. The roller conveyor 1 transports the packaging box 10 from right to left. When the left side of the packaging box 10 moves to the position of the first pressure roller 604, the second electric telescopic rod 601 is activated, causing the hollow plate 602 to move downward, which in turn causes the first fixing frame 603 to move downward, so that the bottom of the first pressure roller 604 contacts the top of the tape 17, pressing the tape 17 and making the tape 17 adhere more tightly to the packaging box 10. When the left side of the packaging box 10 moves to the position of the second pressure roller 605, the second electric telescopic rod 601 is activated. Rod 601 moves the hollow plate 602 downward, which in turn moves the first fixing frame 603 and the second fixing frame 606 downward, causing the first pressure roller 604 and the second pressure roller 605 to move from the top of the packaging box 10 to the side of the packaging box 10. The moving first pressure roller 604 and the second pressure roller 605 press the two ends of the tape 17 onto the side of the packaging box 10 to complete the sealing. Then, the second electric telescopic rod 601 is activated to move the hollow plate 602 upward, preparing for the next operation.

[0019] In this embodiment, an adhesive device 9 is fixedly installed on the top inner wall of the outer shell 2, a third electric telescopic rod 8 is fixedly installed on the top inner wall of the outer shell 2, a cutting blade 7 is fixedly installed at the bottom of the third electric telescopic rod 8, an item sensor 19 is fixedly installed on the top inner wall of the outer shell 2, an inclined plate 11 is provided in contact with one end of the roller conveyor 1, a support plate 12 is fixedly installed on the left outer wall of the inclined plate 11, and a shock-absorbing pad 13 is fixedly installed at the bottom of the support plate 12. The inclined plate 11 and the support plate 12 are set to catch the packaged box 10 after packaging, and the shock-absorbing pad 13 is set to buffer the impact kinetic energy of the packaged box 10 falling. Example 2

[0020] Based on Embodiment 1, a preferred embodiment of the automatic packaging device for logistics transportation provided by the present invention is as follows: Figures 1 to 9 As shown: The blower mechanism 3 includes a blower 301 and a vent 306. The bottom of the blower 301 is fixedly connected to the top of the outer casing 2. An air pipe 302 is connected to the air outlet of the blower 301. A hollow plate 304 is connected to the bottom end of the air pipe 302. A nozzle 305 is connected to the right side of the hollow plate 304. A corrugated pipe 303 is connected to the left side of the hollow plate 304. The bottom end of the corrugated pipe 303 is connected to the interior of the hollow plate 602. The vent 306 is located at the bottom of the hollow plate 602. The blower 301 generates a high-speed airflow, which enters the hollow plate 304 from the air pipe 302. A portion of the airflow enters the nozzle 305 and is blown towards the adhesive. The adhesive device 9 blows the adhesive tape 17 on the adhesive device 9 downwards and to the right, so that the adhesive tape 17 can be better adhered to the packaging box 10. The corrugated pipe 303 is set to ensure that the hollow plate 304 and the hollow plate 602 are connected when the hollow plate 602 moves up and down. The vent 306 is set to allow the airflow to blow the tape 17 from top to bottom, so that the tape 17 is firmly adhered to the packaging box 10. The fan 301 is turned on to generate a high-speed airflow. The airflow flows through the air pipe 302 and the hollow plate 304 in sequence. Part of the airflow enters the nozzle 305 and blows it downwards and to the right onto the adhesive tape 17 on the adhesive device 9. The other part enters the hollow plate 602 from the corrugated pipe 303 and then blows it onto the tape 17 from the vent 306.

[0021] In this embodiment, the air inlet of the fan 301 is connected to a wind box 14 via a pipe. A dustproof net 16 is fixedly installed on the inner wall of the wind box 14, and a protective net 15 is fixedly installed on the inner wall of the wind box 14. The dustproof net 16 is set to prevent dust in the air from being blown onto the tape 17 by the fan 301, which would cause dust to stick to the tape 17 and thus reduce the adhesion of the tape 17. The protective net 15 is set to protect the dustproof net 16. Example 3

[0022] Based on Embodiment 1, a preferred embodiment of the automatic packaging device for logistics transportation provided by the present invention is as follows: Figures 1 to 9As shown: The guiding mechanism 4 includes a lead screw 401, the outer wall of which is threadedly connected to the inner wall of the outer casing 2. A guide plate 403 is rotatably connected to the bottom end of the lead screw 401 via a bearing. A first limiting rod 404 is fixedly installed on the top of the guide plate 403, and the top end of the first limiting rod 404 movably penetrates the outer wall of the outer casing 2. A roller 402 is fixedly installed on the bottom of the guide plate 403, and a handle is fixedly installed on the top of the lead screw 401. The handle facilitates the rotation of the lead screw 401. The guide plate 403 is a folded plate, with its right end tilted upwards and to the right. The guide plate 403 guides the packaging box 10, which has not yet been glued by the gluing device 9, into... The guide plate 402 is used to press down the top layer of the packaging box 10, which opens to both sides, so that the top of the packaging box 10 is flat when the gluing equipment 9 glues the packaging box 10. The roller 402 is set to reduce the friction between the packaging box 10 and the guide plate 403, so that the packaging box 10 can be conveyed to the left by the roller conveyor 1. The screw 401 is rotated according to the height of the packaging box 10. The rotation of the screw 401 drives the guide plate 403 to move up and down, so that the bottom surface of the roller 402 just contacts the top of the packaging box 10. The raised top layer of the packaging box 10 is pressed down little by little along the raised edge on the guide plate 403, so that the top layer of the packaging box 10 is flat. Example 4

[0023] Based on Embodiment 1, a preferred embodiment of the automatic packaging device for logistics transportation provided by the present invention is as follows: Figures 1 to 9As shown: The clamping mechanism 5 includes a first electric telescopic rod 503. An L-shaped plate 502 is fixedly installed on the outer wall of the first electric telescopic rod 503. The outer wall of the L-shaped plate 502 is fixedly connected to the outer wall of the outer shell 2. An insulating cylinder 505 is fixedly installed at the end of the first electric telescopic rod 503 away from the L-shaped plate 502. A first conductive sheet 506 is fixedly installed on the inner wall of the insulating cylinder 505. An insulating plate 5012 is fixedly installed on the inner wall of the insulating cylinder 505. A baffle 5011 is slidably arranged on the inner wall of the insulating cylinder 505. A push rod 5010 is fixedly installed on the inner wall of the baffle 5011. The end of the push rod 5010 facing the insulating plate 5012 moves. A second conductive sheet 507 is fixedly installed on one end of the push rod 5010 facing the insulation plate 5012, penetrating the outer wall of the insulation plate 5012. A connecting plate 509 is fixedly installed on the other end of the push rod 5010. A spring 508 is movably sleeved on the outer wall of the push rod 5010. One end of the spring 508 is fixedly connected to the outer wall of the insulation plate 5012, and the other end of the spring 508 is fixedly connected to the outer wall of the baffle 5011. A clamping plate 501 is fixedly installed on the outer wall of the connecting plate 509 on the side opposite to the push rod 5010. A second limiting rod 504 is fixedly installed on the outer wall of the clamping plate 501. The second limiting rod 504 movably penetrates the outer wall of the outer shell 2. Two electric telescopic rods 503 are provided, located on the front and back of the outer casing 2 respectively, simultaneously clamping and limiting the front and back of the packaging box 10. A ball bearing 18 is fixedly installed on the outer wall of the clamping plate 501 away from the connecting plate 509 to reduce friction between the clamping plate 501 and the packaging box 10. Activating the electric telescopic rod 503 moves the insulating cylinder 505, which in turn moves the insulating plate 5012. The movement of the insulating plate 5012 moves the spring 508, which in turn moves the baffle 5011. The movement of the baffle 5011 moves the push rod 5010, which in turn moves the connecting plate 509. The movement of the clamping plate 501 causes the packaging box 10 to be clamped and limited. When the first electric telescopic rod 503 continues to move the insulating cylinder 505, the connecting plate 509 is blocked by the force that pushes the push rod 5010 to move, thereby blocking the movement of the baffle 5011. At this time, the insulating plate 5012 is driven to continue moving, thereby driving the first conductive piece 506 to move. When the first conductive piece 506 contacts the second conductive piece 507, the first electric telescopic rod 503 is de-energized and no longer drives the insulating cylinder 505 to move, thus avoiding excessive force between the clamping plate 501 and the packaging box 10, which would prevent the packaging box 10 from being transported by the roller conveyor 1.
