[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0025] like Figure 1-4 As shown, the present application provides a logistics packaging device, including a shell 1, a workbench 5 and a heat sealing mechanism 7, the shell 1 is detachably mounted with a mounting roller 2, and a pair of guide rollers 3 are mounted on the top of the shell 1, and a traction mechanism 4 for traction and movement of the packaging bag is also mounted on the top of the shell 1, the workbench 5 is mounted to one side of the shell 1, and the workbench 5 can be fixed to one side of the shell 1 by welding, a working groove 6 is provided on the workbench 5, and the heat sealing mechanism 7 includes a moving plate 71 and a clamping frame 75, and a cutting blade 72 and a heating block 73 are respectively mounted on one side of the moving plate 71 The cutting blade 72 and the heating block 73 can be fixed to one side of the movable plate 71 by bolts, a spring 76 is installed between the clamping frame 75 and the movable plate 71, and the two ends of the spring 76 are respectively fixedly connected to the movable plate 71 and the clamping frame 75, and the inner side of the clamping frame 75 is rotatably connected to two rotating arms 78, and a roller 79 is installed at one end of the rotating arm 78 away from the clamping frame 75, and a rebound part for applying a torsional force to the rotating arm 78 is installed on the clamping frame 75; wherein, a hydraulic rod 10 for driving the heat sealing mechanism 7 to move is also installed inside the workbench 5.

[0026] This solution is applied to the logistics industry for fast and efficient packaging and packing of goods. Specifically, the staff can place the items to be packaged on the workbench 5, and then use the traction mechanism 4 to pull the packaging bag into the working groove 6. At this time, the staff puts the items into the packaging bag, and then starts the hydraulic rod 10 to drive the heat sealing mechanism 7 to move as a whole. The two rollers 79 first contact the packaging bag. As the moving plate 71 continues to move, the two rollers 79 move on the surface of the packaging bag and move away from each other to flatten the packaging bag, which helps to eliminate wrinkles or irregular shapes on the packaging bag and make its surface smoother until the two rollers 79 are in contact with each other. The rollers 79 are stored in the inner side of the clamping frame 75, and the clamping frame 75 can abut against the packaging bag. The clamping frame 75 squeezes and fixes the packaging bag under the elastic force of the spring 76, and fixes the packaging bag tightly to the inner wall of the working groove 6. The movable plate 71 continues to move, so that the cutting blade 72 and the heating block 73 penetrate the clamping frame 75 and contact the packaging bag, and the cutting and heat sealing operations are performed at the same time. The packaging bag to be heat-sealed is pre-leveled by the two rollers 79 to improve the heat sealing effect and ensure the flatness of the cutting incision. Then the hydraulic rod 10 is used to control the heat sealing mechanism 7 to shrink, and the clamping frame 75 releases the restriction on the packaging bag, and the packaging bag falls automatically.

[0027] Among them, the resilient member can apply a torsional force to the rotating arm 78, so that the roller 79 can be in close contact with the packaging bag to improve the leveling effect. In addition, when the hydraulic rod 10 controls the heat sealing mechanism 7 to shrink, the two rotating arms 78 can be reset under the action of the resilient member.

[0028] In addition, when the clamping frame 75 is in contact with the packaging bag, the rotating arm 78 and the roller 79 can be stored inside the clamping frame 75 without obstructing the cutting blade 72 and the heating block 73 .

[0029] It should be noted that the traction mechanism 4 can adopt the current existing technology, using a motor to drive the two traction rollers to rotate, so that the packaging bag between the two traction rollers moves, and the heating block 73 contains heating elements inside, which generate heat by powering on, thereby performing a heat sealing operation.

[0030] like Figure 2 As shown, a reserved groove 9 communicating with the working groove 6 is provided inside the workbench 5 , and the heat sealing mechanism 7 is located inside the reserved groove 9 .

[0031] In this embodiment, the reserved groove 9 is used to accommodate the heat sealing mechanism 7 .

[0032] like Figure 3-4As shown, a rotating shaft 710 is installed at one end of the rotating arm 78. The rotating shaft 710 can be fixed to one end of the rotating arm 78 by welding. The rotating shaft 710 passes through the clamping frame 75 and is rotatably connected to the clamping frame 75. The resilient member includes a torsion spring 711. The torsion spring 711 is sleeved on the outer surrounding of the rotating shaft 710. The two ends of the torsion spring 711 are respectively connected to the rotating shaft 710 and the clamping frame 75. The two ends of the torsion spring 711 are fixedly connected to the rotating shaft 710 and the clamping frame 75.

[0033] In this embodiment, the heat sealing mechanism 7 is driven to move as a whole by the hydraulic rod 10, and the two rollers 79 can first contact the packaging bag. As the movable plate 71 continues to move, the two rollers 79 move on the surface of the packaging bag and move away from each other, and the two rotating arms 78 rotate and compress the torsion spring 711 at the same time, so as to complete the leveling of the packaging bag. After the hydraulic rod 10 controls the heat sealing mechanism 7 to contract, the two rotating arms 78 can be reset under the action of the torsion spring 711.

[0034] like Figure 3 As shown, a telescopic rod 77 is installed between the moving plate 71 and the clamping frame 75. The telescopic rod 77 is located inside the spring 76. Both ends of the telescopic rod 77 can be fixedly connected to the moving plate 71 and the clamping frame 75 by welding.

[0035] In this embodiment, the telescopic rod 77 is provided to limit the movement trajectory of the clamping frame 75 to prevent the clamping frame 75 from being displaced in the vertical direction.

[0036] like Figure 2 As shown, two slide bars 8 are installed on the workbench 5 , and connecting blocks 74 are installed on both sides of the moving plate 71 , and the connecting blocks 74 are slidably connected to the slide bars 8 .

[0037] In this embodiment, the provided sliding rod 8 can guide the movement of the movable plate 71 , thereby improving the stability of the movement of the heat sealing mechanism 7 .

[0038] Working principle:

[0039] The staff can place the items to be packaged on the workbench 5, and then use the traction mechanism 4 to pull the packaging bag into the working groove 6. At this time, the staff puts the items into the packaging bag, and then starts the hydraulic rod 10 to drive the heat sealing mechanism 7 to move as a whole. The two rollers 79 first contact the packaging bag. As the moving plate 71 continues to move, the two rollers 79 move on the surface of the packaging bag and move away from each other to flatten the packaging bag until the two rollers 79 are stored inside the clamping frame 75, and the clamping frame 75 can be close to the packaging bag. The bag is abutted, and the clamping frame 75 squeezes and fixes the packaging bag under the elastic force of the spring 76, and the packaging bag is tightly fixed on the inner wall of the working groove 6. The movable plate 71 continues to move, so that the cutting blade 72 and the heating block 73 pass through the clamping frame 75 and contact the packaging bag, and the cutting and heat-sealing operations are performed at the same time. The packaging bag to be heat-sealed is pre-flattened by two rollers 79 to ensure the flatness of the cutting incision, and then the hydraulic rod 10 is used to control the heat-sealing mechanism 7 to shrink, and the clamping frame 75 releases the restriction on the packaging bag, and the packaging bag falls automatically.
