Description

Technical Field

[0001] This utility model relates to the field of suction mechanism technology, specifically a PET film suction mechanism. Background Technology

[0002] PET film is a thin film made of polyethylene terephthalate. PET film has advantages such as light weight, high strength, good transparency, and non-toxicity and odorlessness. It is widely used in various packaging and protection fields. PET film is often used as a carrier for vacuum metallization. After being metallized by a vacuum metallization machine, it is then laminated with paper. Finally, the aluminum molecular layer is transferred to the cardboard through adhesive action to form metallized cardboard. In addition, PET film is also used in the production of various packaging materials. Due to its good transparency and gas barrier properties, it is often used for food and beverage packaging.

[0003] For example, the PET film suction mechanism disclosed in the authorization announcement number CN222249426U includes: a base, a plurality of arc-shaped support plates fixedly installed on the top of the base, a first motor fixedly connected to the inner side of the corresponding arc-shaped support plate, a bidirectional screw fixedly connected to the output end of the first motor, two rectangular blocks threaded to the outer side of the bidirectional screw, one side of the bidirectional screw rotatably connected to the inside of the corresponding arc-shaped support plate, and two sliding grooves opened on the top of the base, with an L-shaped sliding insert plate slidably connected in each of the two sliding grooves; Although it enables the transmission belt to start conveying the PET film, at the same time the electric push rod is activated, which drives the fixed plate to start descending. Simultaneously, the air pump is activated, which causes the pneumatic suction cup to start picking up the PET film. This causes the L-shaped sliding plates to move away from each other, making it easier for the pneumatic suction cup to pick up larger PET films. The PET film picking mechanism can pick up PET films of different sizes stably, making it more convenient to use. However, this does not solve the problem that existing suction mechanisms of this type are generally not conducive to convenient adjustment of position and height for suction, nor to convenient rotation and flipping angle for suction, which affects the range of rotational suction, and is not convenient for adjusting the position of PET film in irregular positions for suction, thus affecting the flexibility and efficiency of the PET film suction mechanism for suction by rotation and flipping angle. Utility Model Content

[0004] The purpose of this utility model is to provide a PET film suction mechanism to solve the problems mentioned in the background art, such as the inconvenience of adjusting the position and height for suction, the inconvenience of rotating and flipping the suction angle, which affects the range of rotation suction, the inconvenience of adjusting the position of irregularly shaped PET films for suction, and the impact on the flexibility and efficiency of the PET film suction mechanism in terms of rotation and flipping angle suction.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PET film suction mechanism, comprising a frame and a movable plate. The movable plate is disposed outside the frame, a gimbal plate is disposed outside the movable plate, a flipping plate is disposed outside the gimbal plate, and a support frame is disposed outside the flipping plate. Multiple sets of suction cups at equal intervals are mounted on the surface of the support frame. Guide rails are symmetrically mounted on the top of the frame, and a rack is mounted on the top of one side of the guide rail outside the top of the frame. Two sets of sliders are symmetrically mounted on the bottom of the movable plate. The guide rails and the sliders... The moving plate is connected by a sliding connection. A servo motor is installed on the top side wall of the moving plate. A pinion is installed at the output end of the servo motor. The pinion meshes with a rack. Four sets of threaded sleeves with equal spacing are installed at the top of the moving plate. All the threaded sleeves extend through the moving plate to its outside. Four sets of stepper motors are installed at the bottom of the gimbal plate. Each stepper motor has a threaded rod installed at its output end. All the threaded rods extend through the gimbal plate to its outside. All the threaded rods extend through the moving plate to its outside. The threaded rods are threadedly connected to the threaded sleeves.

[0006] Preferably, a power motor is installed at the top of the gimbal plate, a worm gear is installed at the output end of the power motor, and a bearing sleeve is installed inside the gimbal plate.

[0007] Preferably, the bearing sleeve extends through the gimbal plate to its outside, and a rotating shaft is installed inside the bearing sleeve, which extends through the bearing sleeve to its outside.

[0008] Preferably, a worm gear is fitted at the top of the rotating shaft, and the worm meshes with the worm gear.

[0009] Preferably, a top plate is installed at the bottom end of the rotating shaft, and support shafts are movably installed on both sides of the top plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the suction mechanism not only realizes the convenient adjustment of the position and height of the PET film suction mechanism for suction, but also facilitates the convenient rotation and flipping angle for suction, increasing the range of rotation suction, and also facilitates the adjustment of the position of PET film in irregular positions for suction, improving the flexibility and efficiency of the PET film suction mechanism for suction by rotation and flipping angle. When using the PET film suction mechanism, a servo motor drives a pinion to rotate, causing the pinion to move on the surface of a rack. With the sliding support of the guide rail and slider, the pinion drives the moving plate, gimbal plate, flip plate, support frame, and suction cup to move within the working area. When height adjustment is required, a stepper motor drives a threaded rod to rotate, which in turn drives the gimbal plate, flip plate, support frame, and suction cup to rise and fall to the specified height for suction. This facilitates convenient adjustment of position and height for suction, improving the ease of adjusting the position and height of the PET film suction mechanism. An electric push rod drives a rotating shaft to move. Under the limiting support of the movable shaft, the rotating shaft drives the flipping plate, support frame, and suction cup to rotate at a certain angle around the movable shaft. When a certain angle of rotation is required, the power motor drives the worm gear to rotate. The worm gear drives the worm wheel to rotate, and the worm wheel drives the rotating shaft, bearing sleeve, top plate, flipping plate, support frame, and suction cup to rotate at a certain angle around the rotating shaft. This facilitates convenient rotation and flipping angle suction, enabling the PET film suction mechanism to easily perform rotation and flipping angle suction. It increases the range of rotation suction, facilitates the adjustment of the position of PET film in irregular positions, and improves the flexibility and efficiency of the PET film suction mechanism in terms of rotation and flipping angle suction.
