DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model 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 in 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.

[0025] The utility model provides Figure 1-3 The unpacking assembly for an unpacking machine shown comprises a frame 1 and a fixing frame 2 installed inside the frame 1;

[0026] Conveyor belts 3 are provided on the upper side of the fixed frame 2 and near the front and rear sides respectively to transport the cartons for movement;

[0027] The upper outer wall of the fixed frame 2 is provided with a plurality of limit blocks 17 at equal intervals to limit the position of the conveyor belt 3;

[0028] A cutting head 4 is arranged on the upper side of the fixed frame 2 to cut the cover area of ​​the carton, and a telescopic sleeve 13 is arranged on the right side of the cutting head 4. The outer walls of the left and right ends of the telescopic sleeve 13 are fixedly connected with clamping claws 14 to clamp and move the cut cover. The upper outer wall of the fixed frame 2 is fixedly connected with a cylinder 16 near the right side, and the upper outer wall of the cylinder 16 is transmission-connected with a piston rod 15 to limit the rightward movement direction of the carton. When cutting the carton, the carton is first moved to the left side of the conveyor belt 3 through the front feeding device, and the carton is driven to move to the right through the conveyor belt 3. During the movement, the cylinder 16 pushes the piston rod 15 upward. When the carton is connected When the piston rod 15 is touched, the conveyor belt 3 stops moving, and then the cutting head 4 starts working to cut the surrounding area of ​​the upper side of the carton and cut off the box cover. Then the telescopic sleeve 13 drives the clamping jaws 14 to move to the left and right sides, and after the box cover is between the two clamping jaws 14, the telescopic sleeve 13 drives the clamping jaws 14 to remove the box cover and move to the back side of the carton, that is, the cutting work of the carton is completed. Then the piston rod 15 moves down, the conveyor belt 3 works, moves the cut carton to the right, and drives the uncut carton to move synchronously. After the cut carton moves through the area of ​​the cylinder 16, the piston rod 15 is pushed out again to repeat the cutting work of the carton.

[0029] A plurality of shift wheels 18 are equidistantly arranged on the left side of the two limit blocks 17 close to one side of the cylinder 16 to clamp and limit the position of the carton on the conveyor belt 3. When the carton moves and abuts against the piston rod 15, the front and rear sides of the carton will move in accordance with the shift wheels 18 and limit the position, thereby avoiding vibration during subsequent cutting of the carton and position deviation on the conveyor belt 3.

[0030] like Figure 2 and Figure 3 As shown, the left end outer walls of the two limit blocks 17 close to the cylinder 16 are fixedly connected to the fixed plates 20, and the front end outer walls of the two fixed plates 20 are evenly spaced with multiple movable grooves 19 that penetrate front to back to provide space for the shift wheel 18 to rotate, and the lower end inner walls of the multiple movable grooves 19 are fixedly connected to limit the limit columns 22 that penetrate upward into the shift wheel 18 to limit the position and rotation center of the shift wheel 18, and the two fixed plates 20 and the limit blocks 17 are fixedly connected with support feet 21 to limit the position of the fixed plates 20.

[0031] When the carton moves driven by the conveyor belt 3, it will drive the transfer wheel 18 to rotate in the movable groove 19 inside the fixed plate 20. During the rotation, the rotation position of the transfer wheel 18 is limited by the limit column 22, while keeping the transfer wheel 18 in a horizontal state.

[0032] like Figure 1As shown, guide rods 12 are fixedly connected between the inner walls of the left and right ends of the frame 1 and respectively close to the front and rear sides, and the two guide rods 12 are transmission-connected with drivers a6, and a plurality of slide rails a7 are equidistantly fixedly connected between the two drivers a6, and a driver b8 is arranged between the two slide rails a7, and the left end outer wall of the driver b8 is fixedly connected with a slide rail b9, and the left end outer wall of the slide rail b9 is transmission-connected with a slide rod 5 to drive the cutting head 4 to move up and down.

[0033] When the driver a6 moves laterally under the restriction of the guide rod 12, it can synchronously drive the telescopic sleeve 13 and the clamping jaw 14 of the cutting head 4 to move laterally to cut the carton and at the same time take the box cover to calibrate the position of the clamping jaw 14. The driver b8 moves on the slide rail a7 to drive the telescopic sleeve 13 and the clamping jaw 14 of the cutting head 4 to move in the front and back directions to cut the carton and calibrate the position when taking the box cover later. The slide rail b9 can drive the cutting head 4 to move up and down through the slide rod 5 to avoid restricting the movement of the carton when the carton moves.

[0034] like Figure 1 As shown, the right end outer wall of the driver b8 is fixedly connected to the slide rail c10, and the right end outer wall of the slide rail c10 is internally connected to the connecting rod 11 to drive the telescopic sleeve 13 to move up and down. The driver b8 can move forward and backward under the restriction of the slide rail a7, and the driver a6 can move left and right under the restriction of the guide rod 12.

[0035] The connecting rod 11 moves up and down inside the slide rail c10, driving the telescopic sleeve 13 and the clamping claw 14 to drive the clamped box cover to move, and avoiding the situation of restricting the movement of the carton when the carton moves.

[0036] The implementation principle of this embodiment is as follows: when cutting a carton, the carton is first moved to the left side of the conveyor belt 3 by the front feeding device, and the conveyor belt 3 drives the carton to move to the right, and during the movement, the cylinder 16 pushes the piston rod 15 upwards, and when the carton contacts the piston rod 15, the conveyor belt 3 stops moving, and then the cutting head 4 starts working to cut the surrounding area of ​​the upper side of the carton and cut off the box cover, and then the telescopic sleeve 13 drives the clamping jaws 14 to move to the left and right sides, and after the box cover is between the two clamping jaws 14, the telescopic sleeve 13 drives the clamping jaws 14 to The box cover is removed and moved to the back of the carton, and the cutting of the carton is completed. Then the piston rod 15 moves down, and the conveyor belt 3 works to move the cut carton to the right, and drives the uncut carton to move synchronously. After the cut carton moves through the area of ​​the cylinder 16, the piston rod 15 is pushed out again to repeat the cutting of the carton. When the carton moves and abuts against the piston rod 15, the front and rear sides of the carton will fit the transfer wheel 18 to move and limit the position, so as to avoid vibration during the subsequent cutting of the carton and position deviation on the conveyor belt 3.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
