The invention discloses a film opening device which comprises a motor, a linkage rod, a slider, a linear slide rail, a sliding mechanism, a first rotary shaft and a first swinging arm. An adapter block rotating along with an output shaft of the motor synchronously is fixedly arranged on the output shaft of the motor, one end of the linkage rod is pivoted to the adapter block, the other end of the linkage rod is pivoted to the slider, a pivoted point of the linkage rod and the adapter block is staggered from a fixed point of the adapter block and the output shaft of the motor, the slider can slide along the linear slide rail in a first direction, the linear slide rail extending along a second direction is arranged on the slider, one end of the sliding mechanism is slidably arranged in the linear slide rail, the other end of the sliding mechanism is fixed on a first rotating shaft, and the first swinging arm is fixedly connected with the first rotating shaft. Compared with the prior art, the film opening device has the advantages of high opening variability and high opening accuracy.
Description
technical field [0001] The present invention relates to the field of packaging technology, and more specifically relates to a film opening device, which can be used in the automatic packaging process such as paper towels, and is used to automatically stretch the film, so as to facilitate the next process to conveniently pack the paper towel into the film to form a film. in the inner cavity. Background technique [0002] For products such as paper towels, they are generally sold in packs, that is, packaging films are also included on the periphery of the paper towels. The packaging of the paper towels is generally realized by automatic packaging equipment, and the packaging steps are generally: use a suction cup to automatically absorb the pre-processed film bag from the position of the film bag storage room, and the film bag is flat; then use the film to open the mouth The device opens the opening of the film bag, and then uses the conveying equipment to transport the paper...
