[0019] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] In the present utility model, it needs to be explained that if there are directional indications involved in the embodiments of the present utility model (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0021] A box opening structure of a box opening machine, such as Figure 1 As shown, it includes a machine base 1, a swing arm mechanism 2 hinged to the bottom of the machine base, a suction cup 3 is arranged at one end of the swing arm mechanism, and a swing arm gear 4 is arranged at the other end, the swing arm gear is installed at the bottom of the machine base through a rotating shaft, a longitudinal guide rail 5 is arranged at the bottom of the machine base, a slider 6 is installed on the guide rail, and a longitudinal tooth 7 is arranged on the side of the slider facing the swing arm mechanism, a transmission gear 8 is arranged between the longitudinal tooth and the swing arm gear, and the transmission gear is installed at the bottom of the machine base through a rotating shaft, one side of the transmission gear is meshed with the swing arm gear, and the other side is meshed with the longitudinal tooth; a driving mechanism 9 for driving the slider to move up and down along the guide rail is arranged on the machine base, and a limit member 10 for limiting the slider to move different distances and thus limiting the swing arm mechanism to swing at different angles is arranged on one side of the driving mechanism.
[0022] The driving mechanism 9 is a single-bar double-acting cylinder, the main body of which is mounted on a machine base, and the end of a piston rod extending from the main body of the single-bar double-acting cylinder is connected to a slider. The stopper 10 is a locking hydraulic cylinder, the end of the piston rod of which faces the slider. A slide groove is provided on the back of the slider, and the slider is clamped into the guide rail through the slide groove.
[0023] After the locking hydraulic cylinder sets the length of its piston rod extension, the swing angle of the swing arm mechanism is determined accordingly. Figure 1 and Figure 2 As shown, the swing angle of the swing arm mechanism is 45°. At this time, the piston rod is pushed by the single-bar double-acting cylinder, thereby pushing the slider to move downward on the guide rail, and the longitudinal teeth of the slider drive the transmission gear to drive the swing arm gear, so that the swing arm mechanism swings from 45° to 0°, and then the suction cup on the swing arm mechanism sucks the unpacking surface of the cardboard 13 and swings directly from 0° to 45° to perform a flipping action, so that the carton is stretched open, and then the adhesive tape is sealed to prevent the carton from turning back into a cardboard state, realizing the unpacking operation of the 45° carton. After the locking hydraulic cylinder sets the length of its piston rod extension again, as shown in FIG. Figure 3 and Figure 4As shown, the swing angle of the swing arm mechanism is 90°. At this time, the piston rod is pushed by the single-bar double-acting cylinder, thereby pushing the slider to move downward on the guide rail, and the longitudinal teeth of the slider drive the transmission gear to drive the swing arm gear, so that the swing arm mechanism swings from 90° to 0°, and then the suction cup on the swing arm mechanism sucks the opening surface and swings directly from 0° to 90° to perform a flipping action, so that the carton is stretched open, and then the adhesive tape is sealed to prevent the carton from turning back into a cardboard state, realizing the 90° carton opening operation. By adjusting the different lengths of the piston rod of the locking hydraulic cylinder, the swing arm mechanism can swing to different angles, so that the opening angle can be adjusted to be compatible with the opening of cartons of different specifications.
[0024] In another embodiment, an extension plate 11 is laterally extended from the bottom of the machine base toward one side of the swing arm mechanism, and the swing arm gear and the transmission gear are respectively installed on the extension plate through a rotating shaft, and then the swing arm mechanism is installed at the end of the extension plate through the swing arm gear, so that a certain spacing distance is formed between the swing arm mechanism and the machine base. After the locking hydraulic cylinder sets the extended length of the piston rod of the swing arm mechanism, the swing angle of the swing arm mechanism can be 0°~120°, thereby adapting to the unpacking of large-sized cartons.
[0025] In another embodiment, carton guard plates 12 are provided on both sides of the extension plate, and the guard plates block the side edges of the carton to form a supporting force, making it more convenient to open the carton.
[0026] In another embodiment, the swing arm mechanism 2 includes a swing arm 21, one side of the swing arm is provided with a slide rail 22, the other side is provided with a telescopic cylinder 23, a swing arm slider 24 is installed on the slide rail, the swing arm slider is provided with a suction cup mounting plate 25 extending toward the suction cup end, the suction cup is mounted at the end of the suction cup mounting plate, and a connecting plate 26 is installed at the end of the telescopic rod of the telescopic cylinder, and the connecting plate is connected to the suction cup mounting plate. When the swing arm 21 swings to 0°, the telescopic rod is driven by the telescopic cylinder 23 to extend and drive the connecting plate 26, and the connecting plate 26 drives the suction cup mounting plate 25, so that the swing arm slider 24 can move on the slide rail 22, thereby pushing the suction cup to the corresponding position to suck the unpacking surface of the cardboard 13, so as to facilitate the adsorption of the cardboard.
[0027] In another embodiment, the suction cup is a vacuum suction cup, and two vacuum suction cups are provided. Both vacuum suction cups are connected to a vacuum pump through an air pipe. The vacuum pump is used to generate and maintain vacuum for the two vacuum suction cups, so that the suction cups can more easily adsorb cardboard and unpacking is more convenient.
