[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Examples, such as Figures 1-6As shown, the pallet packing machine device provided by this utility model includes a base 1, on which a pallet 2 is mounted. A rotary drive mechanism 3 is located below the pallet 2. A vertical box 4 is mounted on the base 1, and a roller assembly mechanism 5 is located near the vertical box 4. The roller assembly mechanism 5 is used to place the wrapping material 6. Inside the vertical box 4, a lifting drive mechanism 7 is installed to drive the roller assembly mechanism 5 to perform lifting and lowering actions. The lifting drive mechanism 7 uses a transmission pair consisting of a geared motor, a lead screw, and a lead screw slider to adjust the real-time height of the roller assembly mechanism 5, especially to rise and fall with the rotation of the goods driven by the rotary drive mechanism 3, thus meeting the packing requirements of the goods on the pallet 2. Furthermore, the pallet 2 provided by this utility model has an M-shaped fork opening 21, which is suspended above the rotary drive mechanism 3. This allows the forklift arm to directly enter and exit from the fork opening 21, facilitating the transfer of goods after inserting it into the bottom of the goods. Additionally, when placing goods, the forklift arm can also directly lower to allow the goods to rest on the pallet 2. In this way, by using pallets 2 with M-shaped forks 21, it is easier for forklifts to pick up and put down goods, which helps to improve the work efficiency of the packaging station.

[0024] To improve packaging efficiency, this utility model is equipped with an automatic film cutting function. Specifically, the roller assembly 5 is provided with an automatic film cutting mechanism 8, which includes a film cutting support roller 81. The top of the film cutting support roller 81 is provided with a curved arm 82 and a drive arm 83 that rotate synchronously with the film cutting support roller 81. The synchronous connection node can be connected by a key. A drive cylinder 84 is provided on one side of the drive arm 83. The mounting end of the drive cylinder 84 is located on one side of the upright box 4 and its telescopic end faces the drive arm 83. A film-pulling roller 85 is provided at the end of the curved arm 82 away from the drive arm 83. A vertical slot 86 is provided on the side of the upright box 4 facing the film-pulling roller 85. A triangular blade 87 is provided on one side of the slot 86. The triangular blade 87 can be installed on the side of the slot 86 by spot welding or adhesive bonding. In this automatic film cutting mechanism 8, the drive cylinder 84 serves as the trigger structure for the film cutting action. When the extension end of the drive cylinder 84 contacts the drive arm 83, the drive arm 83 drives the curved arm 82 to move. The curved arm 82 swings to cause the film-dispensing roller 85 to press against the wrapping material 6 until it is fastened into the slot 86. The wrapping material 6 and the triangular blade 87 have a certain contact surface and contact pressure. Since the rotary drive mechanism 3 can also drive the goods to rotate, the wrapping material 6 can generate relative displacement with the triangular blade 87 until the film cutting is completed. This equipment conceals the installation position of the triangular blade 87 on the surface of the upright box 4. Compared with the guillotine-type film cutting mechanism and the roller cutting mechanism, the triangular blade 87 in this utility model has higher safety and correspondingly guaranteed film cutting efficiency.

[0025] To improve the coordination performance between the roller assembly mechanism 5 and the automatic film cutting mechanism 8, the roller assembly mechanism 5 provided by this utility model includes a roller bottom plate 51 and a roller top plate 52. A packaging roller 53 is provided on the roller bottom plate 51. A pair of clamping rollers 54 are provided on one side of the packaging roller 53. A tensioning roller 55 is provided on one side of the clamping rollers 54. A positioning roller 56 that cooperates with the tensioning roller 55 is provided on one side of the tensioning roller 55. A stop arm assembly 9 is provided on the top of the positioning roller 56. The packaging roller 53 is coaxially mounted with the winding packaging material 6. A detachable limiting component is provided on the top of the packaging roller 53 to prevent the winding packaging material 6 from jumping. The simplest structural design of the detachable limiting component is, for example, a threaded sleeve + a handle. The diameter of the sleeve is larger than the inner diameter of the winding packaging material 6 to achieve the limiting of the winding packaging material 6, but it does not affect the unwinding action of the winding packaging material 6. The clamping roller 54, with a certain clamping force, can clamp the winding packaging material 6, increasing the number of nodes in the release direction of the winding packaging material 6, and providing better guidance and tension. A tensioning arm is provided at the top of the tensioning roller 55. The structural hole on the tensioning arm is a hole of the same diameter as the roller end of the tensioning roller 55. The hole in the roller base plate 51 that mates with the tensioning roller 55 is an arc hole, ensuring that the tensioning roller 55 has a certain amount of movement. The tensioning arm is connected to the roller end of the positioning roller 56 via a spring, allowing the tensioning roller 55 to dynamically adjust its displacement according to the real-time tension of the winding packaging material 6, thus meeting the tension requirements during the continuous release of the winding packaging material 6. Furthermore, the positioning roller 56, as a coaxial mounting structure of the stop arm assembly 9, can limit the swing amplitude of the bent arm 82, preventing the bent arm 82 from colliding with the vertical box 4 and avoiding the situation where the triangular blade 87 is knocked off due to excessive swing.

[0026] The stop arm assembly 9 provided by this utility model includes a connecting cylinder 91 that mates with the shoulder of the positioning roller 56. A disc plate 92 is provided at the bottom of the connecting cylinder 91, and a limiting nut 93 that is threadedly connected to the shaft end of the positioning roller 56 is provided at the top of the connecting cylinder 91. The plate surface of the disc plate 92 is at the same level as the top surface of the roller top plate 52. At the end of the swing path of the bent arm 82 towards the slot 86, the inner diameter of the bend of the bent arm 82 can contact the cylinder wall of the connecting cylinder 91, and the bent arm 82 will no longer continue to move in this direction, thus playing a safety limiting role.

[0027] Furthermore, the film-cutting support roller 81 provided by this utility model is disposed between the roller top plate 52 and the roller bottom plate 51, and the film-cutting support roller 81 can rise and fall with the roller assembly mechanism 5. The film-cutting support roller 81 serves as the mounting base for the curved arm 82 and the drive arm 83. While the roller assembly mechanism 5 rises and falls, the curved arm 82 and the drive arm 83 can also rise and fall, while the film-cutting drive cylinder 84 remains in a fixed position with its extension and retraction ends avoiding the rising and falling path of the roller bottom plate 51. In this way, the film-dispensing roller 85, located at the end of the curved arm 82, can always remain behind the release path of the winding packaging material 6, forming a clamping relationship with the positioning roller 56 for the packaging material, facilitating subsequent film cutting.

[0028] To facilitate the movement of the forklift's fork arm between the base 1 and the pallet 2, the rotary drive mechanism 3 provided by this utility model includes a fixed outer ring 31, a gear ring 32 is provided on the inner side of the fixed outer ring 31, and an inner disk 33 with a T-shaped longitudinal section is provided on the inner side of the gear ring 32. The outer edge of the inner disk 33 is rotatably sealed with the inner edge of the fixed outer ring 31, and the center of the inner disk 33 is connected to the pallet 2 for transmission. A reduction gear set 34 is provided on the transmission side of the gear ring 32, and the reduction gear set 34 is connected to a motor 35 provided on one side of the vertical box 4. The base 1 has an assembly port at the position of the reduction gear set 34 so that the reduction gear set 34 and the gear ring 32 can establish a transmission connection. The gear ring 32 is connected to the inner disk 33 by a key. The center of the inner disk 33 is connected to the pallet 2 through a bushing, a rotating shaft and a key. Therefore, while the rotary drive mechanism 3 provides rotational power to the pallet 2, it can make the gear ring 32 hidden inside the assembly space between the inner disk 33 and the fixed outer ring 31, avoiding collision between the main transmission components and the forklift. Especially considering that some workshops use hand-push forklifts, the walking wheels of the hand-push forklift will not press on the gear ring 32 when they walk on the fixed outer ring 31 and the inner disk 33, which facilitates the entry and exit of the forklift.

[0029] To improve packaging performance, this utility model includes a pressure plate mechanism 10 suspended vertically above the pallet 2 on the upright box 4. The pressure plate mechanism 10 includes a pressure plate 101, a connecting arm 102 on one side of the pressure plate 101, and an adjusting cylinder 103 on one side of the connecting arm 102. A guide rod is provided on the side of the adjusting cylinder 103, and a fixed slider and a movable slider are provided on the guide rod. The movable slider can rise and fall with the lifting and lowering of the connecting arm. In conjunction with the extension and retraction of the adjusting cylinder 103, it can provide a stable lifting and lowering path for the pressure plate 101, making it easy to press the pressure plate 101 onto the top of the goods to limit and protect the goods.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
