DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] like Figure 1-Figure 6 The floating package pushing mechanism shown is used for a carton sealing machine, which is arranged on the carton sealing machine. The carton sealing machine is mounted on a roller conveyor line. A carton box body 1 with an opening moves on the roller conveyor line and the opening of the carton box body 1 is sealed by the carton sealing machine.

[0025] The carton sealing machine includes a stop assembly 2, which is arranged between the rollers of the roller conveyor line and includes a reference plate 21. The reference plate 21 is moved in the vertical direction by the stop cylinder 22. When the carton box 1 moves through the roller conveyor line, when the carton box 1 approaches the stop assembly 2, under the control of the sensing device, the reference plate 21 rises, and the carton box 1 is able to hit the reference plate 21. After the collision, the carton box 1 will rebound a short distance under the elastic force, so that a gap remains between the carton box 1 and the reference plate 21. In order to compensate for the error caused by this part of the gap, a package pushing mechanism is arranged on the carton sealing machine. The package pushing mechanism includes a package pushing assembly 6. The package pushing assembly 6 can push the carton box 1 to continue moving and make it close to and contact with the reference plate 21, thereby achieving precise positioning.

[0026] The package pushing assembly 6 includes a package pushing beam in contact with the carton box body 1, and the package pushing beam includes a first package pushing beam 61 and a second package pushing beam 62. The first package pushing beam 61 and the second package pushing beam 62 form a four-bar linkage through two parallel rods 63 connected thereto. A package pushing cylinder 64 is connected to the first package pushing beam 61, and a floating joint is provided on the push rod of the package pushing cylinder 64, which can compensate for the error during the stroke. When the package pushing cylinder 64 moves downward, it drives the first package pushing beam 61 to move downward. The four-bar mechanism, the vertical downward force will generate a horizontal force acting on the second push beam 62, so that the second push beam 62 can push the carton box 1. In order to buffer the force, a buffer structure 65 is arranged between the first push beam 61 and the second push beam 62. The buffer structure 65 includes a limit buffer shaft 651 connecting the first push beam 61 and the second push beam 62. The limit buffer shaft 651 is provided with a buffer sleeve 652, which can buffer the downward impact of the push cylinder 64 and increase its stability.

[0027] When the carton box 1 contacts the reference plate 21, the carton box 1 is limited and fixed by the pressing box assembly 3. The pressing box assembly 3 includes a pressing box beam 32. The pressing box beam 32 moves up and down through the pressing box cylinder 31 to press the carton box 1. After the carton box 1 is fixed, the glue is applied to the short side of the opening of the carton box 1 by the glue coating assembly 5. The glue coating assembly 5 is arranged below the roller conveyor line, including a guide rail device 51 arranged along the roller axis direction of the roller conveyor line. The guide rail device 51 is provided with a brush head 52 that moves along its guide rail. The brush head 52 moves to evenly apply the glue. To the short side of the opening of the carton box 1, when the coating is completed, the pressing cover assembly 4 arranged above the blocking assembly 2 moves the box cover at the opening of the carton box 1 to make it buckle on the short side where the glue is applied to bond the carton box 1 to close the opening of the carton box 1. The pressing cover assembly 4 includes a pressing block 41 and a pressing cylinder 42 for pushing the pressing block 41 to move. The pressing cylinder 42 is inclined to the plane where the roller conveyor line is located. The front end of the pressing block 41 is provided with a plurality of paddles 43 for moving the box cover of the carton box 1. When the pressing cylinder 42 moves, the paddles 43 gradually move downward to press the box cover to make it fit more evenly.

[0028] The backstop assembly 2, the box pressing assembly 3, the cover pressing assembly 4, the glue coating assembly 5 and the package pushing assembly 6 are each comprised of two and are symmetrically arranged on both sides of the carton sealing machine, thereby being able to achieve sealing processing of the openings on both sides of the carton box body 1.

[0029] The utility model mentions a floating package pushing mechanism for a carton sealing machine. When in use, the carton box body 1 moves from left to right along the roller conveyor line. When the front side of the carton box body 1 approaches the backstop assembly 2 on the left, the reference plate 21 rises, and the front side of the carton box body 1 elastically collides with the reference plate 21, and the carton box body 1 moves away from the reference plate 21. At this time, the roller of the roller conveyor line stops rotating, and the package pushing assembly 6 pushes the carton box body 1 to move so that its front opening contacts the backstop assembly 2. After contact, the box pressing assembly 3 fixes the carton box body 1 and cooperates with the glue coating assembly 5 and the cover pressing assembly 4 to seal its front opening. When sealing is completed, the roller of the roller conveyor line The drum continues to rotate, driving the carton box 1 to continue to move, and the left reference plate 21 descends to allow it to pass. When the rear opening of the carton box 1 passes the right reference plate 21, the right reference plate 21 rises, and the roller of the roller conveyor line rotates in the opposite direction at this time. The carton box 1 will move to the left and hit the right reference plate 21, and rebound to the right. Similarly, at this time, the package pushing component 6 pushes the carton box 1 to move so that its rear opening contacts the stop component 2. After contact, the box pressing component 3 fixes the carton box 1 and cooperates with the glue coating component 5 and the cover pressing component 4 to seal its rear opening, thereby completing the sealing process of the openings on both sides of the carton box 1.
