DETAILED DESCRIPTION

[0020] The technical scheme of the utility model will be described clearly and completely below in combination with embodiments, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the protection scope of the utility model.

[0021] Please refer to Figures 1-6 It is a box sealing machine with width automatic adjusting structure, including the box sealing machine main body 1, the left and right sides of the box sealing machine main body 1 are provided with the feeding frame 2, and the feeding frame 2 is provided with several groups of roller shafts 3 from left to right in it;

[0022] ​​The width adjusting assembly comprises a bidirectional screw rod 4 rotationally connected between the front and back sides of the left feeding frame 2, guide rods 5 fixedly connected between the left and right sides of the inner walls of the front and back sides of the left feeding frame 2, a first moving frame 6 provided on the outer sides of the front and back sides of the bidirectional screw rod 4 and the two guide rods 5, supports 7 fixedly connected to the bottom of the front first moving frame 6, a rotating shaft 8 rotationally connected in the support 7, a wire roller 9 fixedly connected to the outer wall of the rotating shaft 8, a torsional spring 10 sleeved on the outer side of the rotating shaft 8, the two ends of the torsional spring 10 fixedly connected to the outer wall of the rotating shaft 8 and the side of the adjacent support 7, a pull wire 11 wound on the outer side of the wire roller 9, two second moving frames 12 slidably connected to the outer sides of the two guide rods 5, one end of the pull wire 11 fixedly connected to the side of the adjacent second moving frame 12, a damping rod 13 fixedly connected between the inner walls of the front and back sides of the left feeding frame 2 and located between the two guide rods 5, a damping sliding sleeve 14 fixedly connected in the second moving frame 12 and slidably connected to the outer side of the damping rod 13, a guide plate 15 fixedly connected to the top of the second moving frame 12, a U-shaped frame 16 fixedly connected to the bottom of the left feeding frame 2, a driving structure 17 provided on the bottom of the U-shaped frame 16, a control shaft 18 fixedly connected to the output end of the driving structure 17, a first connecting rod 19 fixedly connected to the top end of the control shaft 18, second connecting rods 20 rotationally connected to the two ends of the first connecting rod 19, and one end of the second connecting rod 20 rotationally connected to the side of the adjacent second moving frame 12.

[0023] It should be noted that the bidirectional screw rod 4 and the motor 21 cooperate to drive the relative movement of the first moving frame 6 on both sides, facilitating the rapid positioning of the guide plates 15 on both sides. The guide rods 5 are used to guide the first moving frame 6 and the second moving frame 12, respectively. The bracket 7 is used to fix the rotating shaft 8. The wire roller 9 is used to store the pull wire 11. The torsional spring 10 is used to keep the pull wire 11 always in tension. The damping rod 13 and the damping sleeve 14 cooperate to provide a certain resistance, slowing down the reset speed of the second moving frame 12 when it is not controlled, avoiding impact caused by too fast speed. The guide plate 15 is used to position the carton. The U-shaped frame 16 is used to fix and support the driving structure 17. The driving structure 17 includes a combination of an electric cylinder and a rotary motor connected by a connecting piece. When the control shaft 18 needs to be controlled, the rotary motor is driven to rise by the electric cylinder, so that the output end of the rotary motor is connected with the control shaft 18. The control shaft 18 is rotated by driving the rotary motor, and the control shaft 18 is locked by the output end of the rotary motor. When the control shaft 18 does not need to be controlled, the rotary motor and the control shaft 18 are separated by controlling the electric cylinder, so that the control shaft 18 is unlocked. The width adjusting assembly can automatically adjust the distance between the guide plates, and can store the distance information of twice positioning at the same time. When the cartons of two specifications are switched, the distance can be quickly adjusted from narrow to wide. The adjustment operation is simple and fast, which effectively improves the time for switching the distance between the guide plates 15 and improves the working efficiency of the cartoning machine.

[0024] The left feeding frame 2 is fixedly connected with a motor 21 on one side. The output end of the motor 21 is fixedly connected with the adjacent end of the bidirectional screw rod 4. The automatic adjustment of the distance between the guide plates 15 can be realized by driving the motor 21. The adjustment operation is simple.

[0025] The first moving frame 6 is provided with a sliding hole on the left and right sides. A threaded hole is formed in the middle of one side of the first moving frame 6. The bidirectional screw rod 4 is threadedly connected with the threaded hole. The sliding hole and the guide rod 5 are in transition fit. The sliding hole is used to guide the first moving frame 6 in cooperation with the guide rod 5. The threaded hole is used to move the first moving frame 6 through thread cooperation when the bidirectional screw rod 4 rotates.

[0026] The utility model discloses in the specific implementation time: first this sealing machine connects external power supply, through the controller control motor 21 work, make it drive bidirectional screw rod 4 rotation, through its with the first moving frame 6's thread cooperation drive first moving frame 6 moves to appropriate position, first moving frame 6 moves and will push second moving frame 12 synchronous movement through contact extrusion, after the interval between the guide plate 15 on second moving frame 12 reaches the wide carton interval, through the controller control drive structure 17 work, make its inside rotary motor and control shaft 18 connect, through its drive control shaft 18 rotation drive first connecting rod 19 rotation, through first connecting rod 19 pull second connecting rod 20 drive both sides second moving frame 12 relative movement, second moving frame 12 moves relative first moving frame 6 moves and will pull the line 11 make wire roller 9 and pivot 8 rotation, make torsional spring 10 deformation storage elasticity, until the interval between the guide plate 15 on second moving frame 12 reaches the narrow carton interval, at this time to the narrow carton loading seals the box operation, after completing through the controller control drive structure 17 work, make its inside rotary motor and control shaft 18 separate, make the line 11 under the torsional spring 10 of releasing elasticity action pull second moving frame 12 reset, further through second connecting rod 20 pull first connecting rod 19 and control shaft 18 rotation, at this time rotary motor no longer restricts control shaft 18, through the sliding of damping slide sleeve 14 on the outside of damping rod 13 to the reset deceleration of second moving frame 12, until second moving frame 12 contact first moving frame 6, complete the interval between the guide plate 15 from narrow interval to wide interval's adjustment.
