Description

Technical Field

[0001] This utility model relates to the field of box making and printing protection technology, and more specifically, to a box making and printing protective film wrapping machine. Background Technology

[0002] Lamination, a protective process in carton printing, involves covering the surface of a cardboard box or paperboard with a transparent film to enhance its protective properties and aesthetics. Lamination effectively prevents printed designs from being damaged by friction and scratches, while also providing waterproof, moisture-proof, and stain-proof protection, extending the carton's lifespan. Furthermore, the laminated surface of the carton is smoother and more even, improving the gloss and visual appeal of the printed designs, thus enhancing the overall quality and market attractiveness of the product. This protective method is widely used in industries with high packaging protection requirements, such as food, pharmaceuticals, and electronics, and is an indispensable and crucial step in modern packaging printing.

[0003] A search revealed an existing patent (publication number: CN220536019U) that discloses a film wrapping machine, including a machine base. The upper front of the machine base has a film fixing structure, and the lower center has a rotating wrapping structure passing through it. The rotating wrapping structure is partially surrounded by a packaging fixing structure. Compared with the prior art, the advantages of this utility model are: This utility model is a film wrapping machine. By manually rotating the rotating rod, the threaded rod is driven to rotate, thereby fixing the product between the fixing plate and the rotating seat. This allows for better control of the fixing force on the product, thus avoiding damage. The setting of limiting holes and locking blocks can be used in conjunction with the threaded rod to adjust the distance between the fixing plate and the rotating seat, making it easier to package different products and increasing the adaptability.

[0004] The structure of the film wrapping machine has obvious defects in actual use: on the one hand, the device cannot ensure that the film remains fully taut during the wrapping process, which can easily lead to the film loosening or wrinkling, affecting the packaging quality and protective effect; on the other hand, the method of fixing the packaged goods by manually controlling the height of the pressure box is difficult to adjust precisely, and can easily damage the box due to improper operation, thus failing to effectively guarantee the integrity of the packaged goods. These problems limit its application effect and reliability in actual production. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a box-making and printing protective film wrapping machine to solve the problems that the film of the packaging machine is easy to loosen, and manual pressing of the box is easy to damage the box body, thus affecting the application effect.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a box-making and printing protective film wrapping machine, comprising: a film-coating platform; a film-coating tensioning device mounted on the film-coating platform, the film-coating tensioning device being used to provide protective film while ensuring that the protective film is taut; a height adjustment device mounted on the film-coating platform, the height adjustment device being used to adjust the height required for fixing the box; a box fixing device mounted on the height adjustment device, the box fixing device being used to fix boxes of different heights; and a box rotating platform device mounted on the film-coating platform, the box rotating platform device being used to drive the box to rotate for wrapping and film coating.

[0007] Preferably, the film-coating tensioning device includes: a rotating platform movably mounted on the top of the film-coating platform, a film-coating take-up roller fixedly mounted on the outer surface of the rotating platform, a motor fixedly mounted on the bottom of the film-coating platform, a rotating platform 2 fixedly mounted on the drive shaft of the motor 1, an mounting frame fixedly mounted on the outer surface of the rotating platform 2, and an auxiliary roller movably sleeved on the mounting frame.

[0008] Preferably, the height adjustment device includes: an adjustment frame fixedly installed on the top of the film-coating platform, an adjustment port is provided on one side of the adjustment frame, an installation frame is adjustablely installed on the adjustment port, and a bolt hole is threadedly connected to one side of the installation frame.

[0009] Preferably, the housing fixing device includes: an electro-hydraulic rod fixedly installed on the mounting frame, a mounting plate fixedly installed at the bottom of the electro-hydraulic rod, a rotating platform three movably installed at the bottom of the mounting plate, and a fixing component assembled at the bottom of the rotating platform three.

[0010] Preferably, the fixing component includes: a mounting sleeve fixedly installed at the bottom of the rotating platform, a spring movably installed inside the mounting sleeve, a fixing rubber rod fixedly installed at one end of the spring, and the fixing rubber rod movably sleeved inside the mounting sleeve.

[0011] Preferably, multiple sets of fixing components are provided, and the multiple sets of fixing components are equidistantly arranged at the bottom of the rotating platform three.

[0012] Preferably, the rotating platform device includes: a rotating platform four movably mounted on the film-coating platform, a gear one fixedly mounted on the bottom of the rotating platform four, a motor two fixedly mounted on the bottom of the film-coating platform, a gear two fixedly mounted on the drive shaft of the motor two, and the gear two meshing with the gear one.

[0013] Preferably, there are two sets of film-stretching devices, which are symmetrically arranged on the top of the film-stretching platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention involves placing the box to be packaged on the rotating platform of a box rotation platform device. The height of the mounting frame is adjusted using the adjusting frame and bolt holes of the height adjustment device to accommodate boxes of different heights. Next, the electric hydraulic rod is activated, causing the mounting plate and rotating platform to descend, allowing the fixing rubber rod in the fixing assembly to tightly adhere to the box surface under the action of springs, achieving a stable fixation. At this time, the motor of the film-stretching device starts, driving the rotating platform and auxiliary roller to rotate, releasing the protective film from the film-winding roller. The auxiliary roller guides the film, ensuring it remains taut throughout the winding process, preventing loosening or wrinkling. Subsequently, the second motor starts, and through the meshing of gears two and one, it drives the rotating platform and the box to rotate, achieving uniform winding of the protective film. This entire process not only ensures the film's tension, improving packaging quality, but also, through the cooperation of the electric hydraulic rod and springs, achieves precise fixing of boxes of different sizes, avoiding damage that might occur with manual operation, thus improving packaging efficiency and reliability.
