Description

Technical Field

[0001] This application relates to the field of wrapping film technology, specifically a fully automatic wrapping film machine. Background Technology

[0002] Packing film is mainly made by extruding a mixture of several different grades of polyethylene resin. Packing film is usually used to wrap and package goods stacked on pallets, making the packaged goods more stable and neat, and also providing a certain degree of waterproofing. Therefore, packing film is widely used in the packaging of goods in foreign trade exports, papermaking, hardware, plastics and chemicals, building materials, food and pharmaceutical industries.

[0003] An existing patent (publication number: CN113895681B) discloses an automatic wrapping device for packing film, characterized by comprising: a base plate; a main support fixedly connected to the upper left side of the base plate, with push handles connected to the middle of the front and rear sides of the main support; a rotating frame connected to the lower right side of the main support via a shaft, with a motor connected to the upper end of the rotating frame and an adjustment groove provided on the upper front side of the rotating frame; and a packing film fixing frame connected to the right side of the rotating frame via a slider, with a sliding plate slidably connected to the lower side of the packing film fixing frame and a telescopic shaft connected to the upper front side of the packing film fixing frame. This automatic wrapping device for packing film can easily and automatically wrap and pack stacked goods, thereby improving the efficiency of wrapping film wrapping. It also allows for easy adjustment of the wrapping film density to meet the packaging needs of different goods and facilitates quick replacement of used packing film.

[0004] However, it was found in the above solution that, in actual use, the thin structure of the rotating frame resulted in insufficient load-bearing capacity, making it unable to support large goods. When it was necessary to adjust the winding density, the adjusting rod had to be manually moved, which resulted in low automation and inconvenience in use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a fully automatic stretch wrapping machine, which has the advantages of improving the load-bearing capacity of the equipment, supporting the wrapping of large goods, and controlling the wrapping density without manual adjustment. It solves the problems of insufficient load-bearing capacity of existing technologies, which cannot support large goods, and the need to manually adjust the wrapping density by moving the adjustment rod, resulting in low automation.

[0006] To achieve the above objectives, this application provides the following technical solution: a fully automatic stretch film packaging machine, including a mounting bracket, a limiting plate fixedly connected to the bottom surface of the mounting bracket, an annular groove formed on the bottom surface of the limiting plate, a slider slidably connected to the inner wall of the annular groove, a drive motor fixedly mounted on the upper surface of the mounting bracket, a rotating frame fixedly connected to the output shaft of the drive motor, the upper surface of the rotating frame fixedly connected to the bottom surface of the slider, and reinforcing ribs fixedly connected to the left and right sides of the rotating frame.

[0007] To enhance the load-bearing capacity of the equipment and support the winding of large goods, the above solution involves installing a limiting plate on the bottom of the mounting bracket, with an annular groove formed on the bottom of the limiting plate. A slider is positioned on the inner wall of the annular groove, forming a sliding connection to limit the slider's movement. The slider's connection to the rotating frame provides support for the rotating frame. When the drive motor rotates the rotating frame, the slider slides along the inner wall of the annular groove, lifting the edge of the rotating frame. Reinforcing ribs are installed on the left and right sides of the rotating frame to further enhance the equipment's load-bearing capacity and support the winding of large goods.

[0008] Furthermore, a base plate is fixedly installed at the bottom of the mounting bracket, and handles are fixedly connected to the left and right sides of the mounting bracket. The upper surface of the base plate is provided with diamond-shaped anti-slip strips arranged at equal intervals, and omnidirectional wheels are fixedly installed on the bottom surface of the base plate.

[0009] The above solution involves placing the base plate at the bottom of the mounting bracket to support it. Handles are installed on the left and right sides of the mounting bracket, facilitating the movement of the entire device by the operator. Diamond-shaped anti-slip strips are placed on the upper surface of the base plate to improve its anti-slip performance. Equally spaced casters are installed on the bottom of the base plate, enabling easy movement of the entire device.

[0010] Furthermore, a servo motor is fixedly installed on the bottom surface of the rotating frame, and a connecting rod is fixedly connected to the output shaft of the servo motor. Roller bearings are fixedly installed at the top and bottom ends of the connecting rod, and the outer surface of each roller bearing is fixedly installed to the inner wall of the rotating frame.

[0011] The above scheme involves mounting the servo motor on the bottom surface of the rotating frame, establishing a fixed connection by mounting the connecting rod on the output shaft of the servo motor. The servo motor enables the connecting rod to rotate, and its speed can be adjusted during operation to control the connecting rod's rotational speed. Roller bearings are installed at the top and bottom of the connecting rod and connected to the rotating frame, thus achieving the installation of the roller bearings. Roller bearings have a large radial load-bearing capacity, a low coefficient of friction, and are suitable for high-speed rotation.

[0012] Furthermore, a pulley is fixedly connected to the outer surface of the connecting rod, a timing belt is engaged on the outer surface of the pulley, a second pulley is engaged on the inner wall of the timing belt, and a threaded rod is fixedly connected to the inner wall of the second pulley.

[0013] The above scheme involves mounting pulley one on the surface of the connecting rod and setting it as fixed, placing the timing belt on the surface of pulley one, and connecting pulley two to the timing belt. Through the connection of pulley two, timing belt, and pulley one, pulley two can rotate synchronously with pulley one. The threaded rod is mounted on the inner wall of pulley two and set as a fixed connection. The threaded rod can rotate through pulley two, and the speed of the connecting rod can be adjusted through a servo motor, thereby allowing the speed of the threaded rod to be adjusted.

[0014] Furthermore, the outer surface of the threaded rod is rotatably connected to the inner wall of the rotating frame, and a limit block is threadedly connected to the outer surface of the threaded rod.

[0015] The above scheme connects the surface of the threaded rod to the inner wall of the rotating frame, setting it as a rotary connection to achieve the limiting effect of the threaded rod. The limiting block is installed on the surface of the threaded rod, setting it as a threaded connection. The rotation of the threaded rod allows the limiting block to rise and fall. The speed of the limiting block is changed by changing the rotation speed of the threaded rod.

[0016] Furthermore, a limiting groove is provided on the front of the rotating frame, and the inner wall of the limiting groove is slidably connected to the outer surface of the limiting block.

[0017] The above solution involves creating a limiting groove on the front of the rotating frame to achieve positioning of the limiting groove. The limiting groove is then connected to the limiting block in a sliding connection, thereby achieving the limiting effect on the limiting block through the limiting groove.

[0018] Furthermore, a mounting frame is fixedly connected to the front of the limiting block, an electromagnet module is fixedly installed on the inner wall of the mounting frame, and an armature module is provided on the right side of the electromagnet module.

[0019] The above scheme involves installing the mounting frame on the front of the limiting block, installing an electromagnet module on the inner wall of the mounting frame, and placing the armature module on the right side of the electromagnet module. The electromagnet module and the armature module are combined to form a complete electromagnetic lock, which facilitates rapid adsorption and separation.

[0020] Furthermore, two locking blocks are fixedly connected to the front of both the electromagnet module and the armature module, and a fixing post is provided below the rotating frame. The inner wall of each locking block is in contact with the outer surface of the fixing post.

[0021] The above scheme involves installing the locking block on the front of the electromagnet module and the armature module, placing the fixing post below the rotating frame, and connecting the top and bottom ends of the fixing post with the grooves on the corresponding locking block surface. This enables quick installation and removal of the fixing post, facilitating the replacement of the membrane roll and improving work efficiency.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This fully automatic stretch wrapping machine incorporates components such as a limiting plate, slider, rotating frame, and reinforcing ribs. The limiting plate features an annular groove, and the slider is positioned on the inner wall of this groove, connecting to the rotating frame for support. When the drive motor rotates the rotating frame, the slider slides along the inner wall of the annular groove, lifting the edge of the rotating frame. The reinforcing ribs enhance the machine's load-bearing capacity, supporting the wrapping of large goods. A servo motor drives a connecting rod, which, through pulley one, a synchronous belt, and pulley two, rotates the threaded rod. The servo motor allows for speed adjustment during operation, making the threaded rod's speed adjustable for controlled wrapping density without manual adjustment. Attached Figure Description

[0041] This embodiment of a fully automatic stretch wrapping machine includes components such as a limiting plate 2, a slider 4, a rotating frame 6, and reinforcing ribs 7. The limiting plate 2 is installed, and an annular groove 3 is formed. The slider 4 is placed on the inner wall of the annular groove 3 and connected to the rotating frame 6 to support the rotating frame 6. When the drive motor 5 drives the rotating frame 6 to rotate, the slider 4 slides on the inner wall of the annular groove 3, which can lift the edge part of the rotating frame 6. With the reinforcement ribs 7, the load-bearing capacity of the equipment can be improved, supporting the wrapping of large goods. By setting a servo motor 11 to drive the connecting rod 12, the threaded rod 17 can be rotated through the connection of pulley 14, synchronous belt 15 and pulley 16. The servo motor 11 can adjust the speed during operation, so the speed of the threaded rod 17 is adjustable, which makes it easy to control the wrapping density without manual adjustment.

[0042] It should be noted that the servo motor 11 is a motor that converts electrical signals into angular displacement or angular velocity. When working, it can adjust the speed, thereby making the speed of the threaded rod 17 adjustable and the lifting speed of the limit block 18 adjustable, thus achieving the effect of controlling the winding density.

[0043] The working principle of the above embodiments is as follows:

[0044] When goods need to be wrapped and packaged, first push the device to one side of the goods using handle 25, pull the packaging film onto the goods and fix it. Then start the drive motor 5 to make the rotating frame 6 rotate. The connection between the annular slide groove 3 and the slider 4 ensures the stability of the rotating frame 6 during rotation. By setting the reinforcing rib 7 to cooperate with the slider 4, the load-bearing capacity of the equipment can be improved, supporting the wrapping of large goods. During packaging, the servo motor 11 is started synchronously to make the connecting rod 12 rotate. The connecting rod 12 drives the pulley 14 to rotate. Through the connection of pulley 14, the synchronous belt 15 and the pulley 16, the threaded rod 17 can rotate. Through the connection between the threaded rod 17 and the limit block 18, the limit block 18 can be raised. By adjusting the speed of the servo motor 11, the speed of the threaded rod 17 can be adjusted, thereby achieving the effect of controlling the wrapping density without manual adjustment. When the film roll is used up, by disconnecting the connection between the electromagnet module 21 and the armature module 22, the fixing post 24 can be disassembled, thereby realizing the quick replacement of the film roll and improving the work efficiency.
