Technical Field
[0001] This utility model relates to stretch film, and in particular to a fully automatic stretch film winding device. Background Technology
[0002] Stretch film, also known as wrapping film, has excellent stretch properties and a certain degree of self-adhesion on its surface. Thanks to this, stretch film is widely used in the packaging industry. Many businesses wrap products with stretch film before shipping to achieve the purpose of protection, fixation and convenient transportation.
[0003] Existing fully automatic stretch film wrapping machines can only release the stretch film by simply clamping the core tube of the rolled stretch film with a column. As a result, the core tube of the rolled stretch film has poor rotation flexibility at the elevator on one side of the wrapping machine. To address the above problem, a fully automatic stretch film wrapping device disclosed in Chinese Patent No. CN202223092354.2 is provided. By setting a film loading mechanism at the elevator of the wrapping machine for the sleeve of the rolled stretch film core tube, the film loading mechanism can provide a flexible mounting structure for the stretch film roll, so that the stretch film roll can be smoothly rotated and released, ensuring the smooth release and automatic wrapping of the stretch film at the wrapping machine.
[0004] However, the equipment disclosed in the above patent does not have the ability to cut stretch film. After the stretch film is wound, it cannot be automatically cut and technicians need to cut the stretch film manually, which is inconvenient. In order to solve this problem, we propose a fully automatic stretch film winding device. Utility Model Content

[0028] Example:
[0029] like Figures 1 to 4As shown, a fully automatic stretch film wrapping device includes a base 11, on which a rotating seat 13 driven by a servo motor 12 is rotatably connected. An auxiliary ramp 14 is provided on the front side of the base 11, allowing technicians to move goods onto the rotating seat 13 with the assistance of the auxiliary ramp 14. After wrapping, technicians can also unload the goods from the rotating seat 13 using the auxiliary ramp 14. Furthermore, a support ring 33 is installed on the base 11, with its upper side abutting against the lower side of the rotating seat 13, thereby enhancing the structural stability of the rotating seat 13 and enabling it to withstand heavier goods.
[0030] A lifting seat 15 is fixedly connected to the rear side of the base 11. A lifting groove 35 is provided in the lifting seat 15. A drive screw 34 is rotatably connected in the lifting groove 35. A second servo motor 36 for driving the drive screw 34 is installed on the lifting seat 15.
[0031] Furthermore, a lifting frame 16 is slidably connected inside the lifting seat 15, and the rear side wall of the lifting frame 16 abuts against the bottom wall of the lifting groove 35, thereby limiting the lifting frame 16 so that it can only move vertically up and down.
[0032] A roll frame 17 is detachably connected to the lifting frame 16. Technicians place the stretch film roll onto the roll frame 17. During wrapping, a portion of the stretch film roll is pulled out and attached to the outer surface of the goods to be packaged. Subsequently, the first servo motor 12 drives the rotating seat 13 and the goods on the rotating seat 13 to rotate, and the lifting frame 16 drives the stretch film roll to move up and down, thereby enabling the stretch film to wrap and package the goods.
[0033] The roll frame 17 includes a connecting ring 24 and a rotating rod 25. The specific structure of the roll frame 17 is as follows: a round-bottomed groove 28 is provided in the lifting frame 16; a rotating ball head 29 is integrally formed on the lower side of the rotating rod 25; the rotating ball head 29 is rotatably connected to the round-bottomed groove 28; a tray 37 for placing the stretch film roll is fixedly connected to the outer curved surface of the rotating rod 25; the rotating rod 25 is rotatably connected to the inner curved surface of the connecting ring 24; a limiting groove 26 is provided in the inner curved surface of the connecting ring 24; a limiting ring 27 is integrally formed on the outer curved surface of the rotating rod 25; and the limiting ring 27 is rotatably connected to the limiting groove 26. Through the above structure, the rotating rod 25 can rotate relative to the connecting ring 24 without falling off the connecting ring 24.
[0034] The connecting ring 24 is fixed to the lifting frame 16 by bolts, so that the connecting ring 24 cannot rotate relative to the lifting frame 16, thereby achieving the purpose of fixing the roll frame 17 to the lifting frame 16. When the stretch film is wrapped around the goods, the rotating rod 25 rotates relative to the connecting ring 24, thereby driving the stretch film roll to rotate flexibly.
[0035] A rotating shaft 19 is rotatably connected to the lifting frame 16 on one side of the roll frame 17. A rotary cylinder 20 for driving the rotating shaft 19 to rotate is installed on the lifting frame 16. A cutting blade holder 18 is fixedly connected to the outer curved surface of the rotating shaft 19. A cutting blade 23 is fixedly provided on the cutting blade holder 18. Furthermore, a limit rod 21 is installed on the lifting frame 16, and a blade groove 22 is provided on the limit rod 21.
[0036] During the wrapping process, the stretch film is always attached to the outer curved surface of the limiting rod 21 near the cutting blade holder 18, and the cutting blade 23 does not contact the stretch film to avoid cutting the stretch film during the wrapping process. After the stretch film has finished wrapping the goods, the rotary cylinder 20 drives the rotating shaft 19 to rotate, thereby causing the cutting blade holder 18 to swing until the cutting blade 23 is inserted into the blade groove 22, thereby cutting the stretch film and achieving the goal of automatically cutting the stretch film after the goods are wrapped and packaged.
[0037] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
