Abstract: A tape applying device includes a plate, front and rear swinging arms pivoted on the plate, a pressing wheel pivoted on each of the swinging arms to make an adhesive tape stick on a box, a connecting rod pivoted to both the front and the rear swing arms, a cutting mechanism interposed between the front and the rear swinging arms to sever the adhesive tape, a first restoring extension spring joined to the connecting rod, and a second restoring extension spring joined to the rear swinging arm; the front swinging arm is co-movable with the rear swinging arm and the connecting rod, and it has no extension spring directly connected thereto therefore the front pressing wheel won't produce such a reacting force as to cause a box to cave in when the box is moved rapidly onto the front pressing wheel for the adhesive tape to stick thereon.

Abstract: An automatic bagging machine using cool-shrinking film includes mainly a machine body, a bag conveying device, a bag sealing device, a bag sucking device, and a bag supporting device combined on the machine body. The bag conveying device sends continual bags to the bag sucking device to suck and stick to a lower opening of each bag to open it for a first stage. Then the four corners of the opening of the bag are respectively sucked to stick to suck drums fixed with air suckers by operation of position air pressure cylinders beside each air sucker. Then the bag is expanded out to a preset medium size, not falling down during expanding process. Next, the bag supporting device continually sends out a certain length of the bag to be positioned in the bag supporting device, which then expands the bag again to a preset maximum size. The bag together with the bag supporting device are lowered down by elevating frames to release the bag to cover and surround products (or cartons) together with the storing plate.

Abstract: A material picking device and a forming device for an automatic circulating carton opening machine are fixed on the table of the machine. The material picking device has a revolving unit including a swinging arm, two rotatable gear units fixed at two ends of the swinging arm. Each gear unit has an outermost belt wheel connected to a parallel arm, and a sucking disc fixed with the parallel arm. The forming device has a forming guide plate fixed on an intermediate portion of the table of the machine in front of the revolving unit and located at one side of the moving route of the swinging arm. The two parallel arms fixed with the sucking discs are moved horizontal to let the sucking discs to alternately and continuously pick a carton material board out of the material feed device of the machine to carry onto the forming guide plate for forming a carton shape. So operating of the machine is speeded up largely.

Abstract: A carton-shaping machine includes a material conveying mechanism, an opening mechanism, a shaping mechanism, and a band sticking mechanism combined on a worktable. A vertical and a horizontal cylinder of the opening mechanism control fixing members to force needles on them insert firmly in an upper folding portion of a carton and turn the carton to extend to standing position so as to permit opening process operated with accuracy. Then, the band sticking mechanism may seal the bottom portion of the carton and the carton is moved to the packing process, without any need of manual work to turn it for a right angle to stand upright.

Abstract: A cap-folding and sealing machine for common or retrieved cartons includes a table, a folding device, a first cap frame, a second cap frame, and a double sealing device. The folding device includes upper swing rod units, a side pressing unit, and a folding guiding arm for swinging and folding a front cap, a rear cap, and two side caps with help of the first cap frame after a carton is moved into the table. Then the carton is moved into the second cap frame and the double sealing device, which seals the upper and the lower side with adhesive tapes by means of two pairs of upper main and lower main sealing members of the double sealing device. The two pairs of the sealing members alternately perform sealing operation so that sealing may be kept on continuously without stopping the machine for replacing adhesive tapes even when used up or ripped off.
