Description

Technical Field

[0001] The present application relates to the technical field of corrugated paper box production, and in particular to a corrugated paper box edge sealing device. Background Art

[0002] Corrugated boxes are made of corrugated cardboard through die-cutting, creasing, nailing or gluing;

Cartons are edge-sealed on a conveyor belt and turned over by a rotating motor, an electric telescopic rod and a clamping plate on the side to switch the edge-sealing surface. Since there is no lifting mechanism, interference will occur between the turning of the carton and the conveyor belt, and the carton cannot be turned over stably. Once the linear position of the edge sealing is offset from the active position of the tape edge sealing, the edge sealing effect cannot be achieved. Secondly, the moving path of the tape edge sealing is certain, and the placement position of the carton on the conveyor belt needs to be accurately guaranteed. Obviously, it is impossible to achieve this accurately by manual labor, which causes troubles to the edge sealing and affects efficiency.

[0005] In order to solve the above problems, this application proposes a corrugated box edge sealing device.

The positioning component 3 can position the carton from both sides of the front end and place it in the middle of the conveyor belt 12, thereby laying a foundation for the quality of the edge sealing later.

[0022] Reference Figure 1 - Figure 2 The lifting component 2 includes a fixing frame 21 fixed at the lower end of the bracket 11, a lifting plate 22 located above the fixing frame 21, and a lifting cylinder 23 fixed at the bottom of the fixing frame 21. The output end of the lifting cylinder 23 is fixed to the bottom of the lifting plate 22. The lifting plate 22 is parallel to the upper surface of the conveyor belt 12, and the lifting plate 22 is moved between the hollow part of the conveyor belt 12 and directly above the hollow part through the lifting cylinder 23. The middle of the conveyor belt 12 is set to a hollow state. Then, with the cooperation of the lifting component 2, the edge-sealed carton is lifted, and the other surfaces are rotated as needed to seal the edges, so as to ensure the stability of the carton flipping, avoid interference with the conveyor belt 12, and ensure the accuracy of edge sealing.

[0023] Reference Figure 3The positioning assembly 3 includes a transmission box 31 fixed on the bracket 11 and side positioning plates 32 symmetrically arranged at the upper ends of both sides of the bracket 11, as well as a positioning wheel 33 rotatably arranged at one end of the side positioning plate 32 and a front positioning plate 34 located at the hollow part of the conveyor belt 12. There are symmetrical rotating shafts 35 rotating at both ends of the transmission box 31. A spline hole 36 is opened at the upper end of the rotating shaft 35. A spline rod 37 is fixed to the bottom of the side positioning plate 32 away from the positioning wheel 33. The spline hole 36 is plug-connected with the spline rod 37. The rotating shaft 35 is integrally connected with the side positioning plate 32 through the spline hole 36 and the spline rod 37. The setting of the spline hole 36 and the spline rod 37 can adjust the matching angle between the side positioning plate 32 and the front positioning plate 34 according to the size of the carton.

[0024] Reference Figure 3 An internal threaded sleeve 38 is also rotatably provided on the transmission box 31, a lead screw 39 cooperating with the internal threaded sleeve 38 is fixedly provided at the bottom of the front positioning plate 34, a driving motor 310 whose output end is coaxially fixed with the bottom of the internal threaded sleeve 38 is fixed at the bottom of the transmission box 31, fixed guide rods 311 are provided at both ends of the bottom of the front positioning plate 34, a guide sleeve 312 cooperating with the guide rod 311 is fixed on the transmission box 31, the internal threaded sleeve 38 cooperates with the lead screw 39, and is used for the front positioning plate 34 to limit and disengage the carton, and the guide rod 311 and the guide sleeve 312 have a structural stability effect.

[0025] Reference Figure 3 A transmission component 313 is also provided between the output end of the driving motor 310 and the rotating shafts 35 at both ends of the transmission box 31. The rotating shaft 35 drives the rotating shafts 35 at both ends to rotate synchronously in different directions through the transmission component 313. The transmission component 313 is composed of synchronous wheels, synchronous belts, gears, connecting rods, etc., and the figure only shows one of the matching methods of the transmission component 313.

[0026] Working principle: The middle of the conveyor belt 12 is hollowed out, which will not affect the conveying of the carton. According to the size of the carton, the insertion angle of the spline hole 36 and the spline rod 37 is selected to ensure that after the front end of the carton contacts the front positioning plate 34, the positioning wheels 33 at both ends contact the side of the carton at the same time;

[0027] The conveyor belt 12 rotates to work, and the carton is placed on the conveyor belt 12. The driving motor 310 drives the internal threaded sleeve 38. The internal threaded sleeve 38 drives the front positioning plate 34 to move upward and protrude from the upper surface of the conveyor belt 12 through the spiral of the lead screw 39. The guide rod 311 follows and slides upward inside the guide sleeve 312. While the front positioning plate 34 moves upward, the output end of the driving motor 310 drives the rotating shafts 35 at both ends to rotate synchronously in different directions through the transmission component 313. The rotating shaft 35 drives the side positioning plates 32 to move toward the middle. The positioning wheels 33 at both ends contact with the two side surfaces of the carton at the same time. At this time, the carton is located in the middle of the conveyor belt 12. The reverse driving motor 310 drives the front positioning plate 34 to move to the lower end of the conveyor belt 12, and the side positioning plate 32 rotates outward to break away from the restriction on the carton. The carton is smoothly and accurately delivered to the position just below the edge sealing of the tape.

[0028] The output end of the lifting cylinder 23 lifts the lifting plate 22 upward, and the lifting plate 22 drives it upward from the bottom of the carton to perform edge sealing on one side. When it needs to be flipped, the electric push rods at both ends clamp the carton, and the lifting plate 22 moves downward to make room for the flipping of the carton. The motor drives the carton to flip. After the reversal is completed, the lifting plate 22 is supported on the bottom of the carton again, and the tape performs edge sealing on the flipping side. After the edge sealing is completed, the lifting cylinder 23 drives the lifting plate 22 to move to the lower end of the conveyor belt 12, and the carton falls on the conveyor belt 12 and is transmitted backward.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
