Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a film wrapping device for object packaging. Background Technology

[0002] In order to facilitate transportation, the logistics industry needs to stack boxed goods on pallets and then wrap them with stretch film. This not only prevents the goods from collapsing during transportation, but also provides some protection against dust and rain.

[0003] A search revealed a Chinese patent document disclosing a film wrapping device for object packaging [Announcement No.: CN219806996U]. This film wrapping device for object packaging includes: two U-shaped support rods and a disc, the disc being positioned above the two U-shaped support rods; and a rotating rod movably embedded in the center of the top of the disc.

[0004] The device disclosed in this patent can wrap and wrap objects when in use. However, when wrapping items, there is no restriction on the items, and the wrapping force can easily cause the items to tip over, which will affect the quality of the film wrapping and have an adverse effect on the work. In addition, when wrapping, the device is only connected to the ground through casters. In this way, the contact area is small and the friction and pressure are insufficient. As a result, the device may move during operation, which will affect the use of the device. Utility Model Content

[0005] The purpose of this invention is to provide a film wrapping device for object packaging, so as to solve the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, a film wrapping device for packaging objects includes a support frame 1, lifting mechanism bodies 2 are provided on both sides of the surface of the support frame 1, a support plate 3 is provided at the other end of the lifting mechanism body 2, a drive mechanism body 4 is provided on the surface of the support plate 3, a wrapping mechanism body 5 for wrapping the packaging film is provided at the output end of the drive mechanism body 4, a crossbeam 6 is fixed on the surface of the support frame 1, and a housing 7 is fixed on the surface of the crossbeam 6. The device also includes:

[0022] A lifting mechanism 8 is installed inside the housing 7 to lift the packaging. An auxiliary block 14 is provided at the output end of the drive mechanism body 4 to cooperate with the lifting mechanism 8. A friction mechanism 10 is provided on the surface of the lifting mechanism 8.

[0023] When this utility model wraps the packaging through the drive mechanism body 4 and the wrapping mechanism body 5, the lifting mechanism 8 can make the wrapped item adhere to the surface of the auxiliary block 14. Then, under the action of the lifting mechanism 8 and the auxiliary block 14, the item is clamped to ensure the stability of the item during wrapping. In addition, under the action of the friction mechanism 10, the contact area between the device and the ground can be increased, thereby improving the stability of the device during operation.

[0024] The lifting mechanism 8 includes a motor 81 fixed inside the housing 7. Both sides of the output shaft of the motor 81 are provided with first threaded rods 82 via bevel gear transmission. A first engagement block 83 is engaged with the surface of the first threaded rod 82. A hinge plate 84 is hinged to the surface of the first engagement block 83. A placement plate 85 is hinged to the other end of the hinge plate 84. The placement plate 85 and the crossbeam 6 are movably connected. In this embodiment, through the arrangement of the motor 81, the first threaded rod 82, the first engagement block 83, the hinge plate 84 and the placement plate 85, the first threaded rod 82 rotates under the action of the motor 81, and the first engagement block 83 engaged with the surface of the first threaded rod 82 can move. Then, the hinge plate 84 hinged to the surface of the first engagement block 83 can drive the placement plate 85 to rise and fall.

[0025] The motor 81 is a servo motor and has a built-in brake device. In this embodiment, this setting improves the accuracy of the motor 81 when it rotates, and under the action of the brake device, the first threaded rod 82 and the first meshing block 83 can be stably stopped at a specified angle.

[0026] Limiting frames 9 are rotatably provided on both sides of the surface of the first threaded rod 82. The other end of the limiting frame 9 is fixed to the surface of the cross frame 6. In this embodiment, the limiting frame 9 provides a limit for the rotation of the first threaded rod 82, thereby improving the stability of the first threaded rod 82 during operation.

[0027] The friction mechanism 10 includes a second threaded rod 101 driven by bevel gears to one end of the first threaded rods 82 on both sides. A second engagement block 102 engages with the surface of the second threaded rod 101. A slide rod 103 is fixed inside the cavity of the second engagement block 102. A slider 104 is slidably disposed on the surface of the slide rod 103. A contact block 105 is fixed to the other end of the slider 104. A spring 12 is sleeved on the surface of the slide rod 103. One end of the spring 12 is fixed to the cavity of the second engagement block 102, and the other end of the spring 12 is fixed to the contact block 105. In this embodiment, the surface of block 104 is provided with a second threaded rod 101, a second meshing block 102, a slide rod 103, a slider 104, and a contact block 105. When the first threaded rod 82 rotates, the second threaded rod 101, which is driven by the first threaded rod 82, can mesh with the second meshing block 102. Then, under the action of the slide rod 103, the slider 104 and the contact block 105 work. When the contact block 105 is in contact with the ground, the friction between the device and the ground can be increased.

[0028] The surface of the mating block 105 is fixed with several anti-slip ridges 11, and the two sides of the support frame 1 are provided with sliding grooves 13. The second mating block 102 slides on the surface of the sliding groove 13. In this embodiment, by setting the anti-slip ridges 11 and the sliding grooves 13, the friction between the device and the ground is increased under the action of the anti-slip ridges 11, and the sliding of the second mating block 102 is limited under the action of the sliding grooves 13.

[0029] Working principle: During operation, the wrapping mechanism body 5 wraps the packaging under the action of the drive mechanism body 4. The working principle can be referred to as a film wrapping device for object packaging with application number CN202320974547.6. When wrapping the packaging, the operator can place the package on the surface of the placement plate 85 and use the motor 81. When the motor 81 is working, the first threaded rod 82 and the first meshing block 83 are engaged by the action of the bevel teeth on both sides. Then, under the action of the hinge plates 84 on both sides, the placement plate 85 is raised. When the placement plate 85 drives the package to abut against the auxiliary block 14, the operation of the motor 81 can be stopped. Then, under the joint action of the placement plate 85 and the auxiliary block 14, the package is clamped to prevent the package from shifting due to the film wrapping force. Since the placement plate 85 raises the item, the operator needs to modify the working height of the wrapping mechanism body 5. The modification can be made by the lifting mechanism body 2.

[0030] Furthermore, when the first threaded rod 82 rotates, the second threaded rod 101 and the second meshing block 102 can cause the contact block 105 inside the second meshing block 102 to move downward. This increases the friction between the device and the ground when the contact block 105 is in contact with the ground. Additionally, the sliding rod 103, the slider 104, and the spring 12 can buffer the stroke of the contact block 105, preventing interference with the path distance of the placement plate 85 and improving the practicality of the device.
