Description

Technical Field

[0001] The utility model relates to a carton tape packaging and packing structure, in particular to a flip-top carton tape packaging and packing mechanism, belonging to the technical field of packaging. Background Art

[0002] Product packaging usually requires the use of cartons, which need to be sealed with tape at the opening to prevent the carton from falling apart and the product from leaking out.

[0003] At present, most of the cartons are in the form of a whole body surrounded by four panels, with four panels on the upper and lower sides opening and closing towards the center line in pairs, forming a middle seam at the closed position. Figure 1 As shown; Finally, the tape needs to be sealed along the middle seam; When this kind of carton is sealed with tape, since the middle seam is located on the upper plane of the entire carton, it is equivalent to only using an ordinary baler to seal the tape on the plane, and the operation is relatively easy;

[0004] For another special structure of flip carton, it may be necessary to seal the edges of the carton with tape; the tape sealing of this flip carton occurs at the corners of the box, that is, two sides with a 90° angle need to be sealed, not just one flat side; this kind of tape application is very difficult to operate, and it cannot be packaged by ordinary packaging machines or the edges of the carton can only be sealed manually;

[0005] Therefore, it is necessary to develop a packaging mechanism suitable for the tape packaging of such flip-top cartons to adapt to the requirements of such working conditions and improve the efficiency of carton packaging. Utility Model Content

[0006] In view of the above-mentioned technical problems, the purpose of the present invention is to provide a flip-top carton tape sealing and packaging mechanism, which has a simple structure to solve the problem that the edges of the carton cannot be sealed in the prior art, meets higher carton tape packaging requirements, and solves the problem of low efficiency of carton sealing operations.

[0007] In order to achieve the above-mentioned purpose, the technical scheme adopted by the utility model is: a flap carton tape packaging and packaging mechanism, comprising: a tape rolling mechanism, the tape rolling mechanism is arranged in a rolling mechanism frame, a fixing frame is fixedly arranged below the rolling mechanism frame, and a tape wheel for setting a tape roll is arranged on the fixing frame; the starting end of the tape roll is wound around the tape rolling mechanism and led out so that the adhesive surface of the tape faces the carton; a primary corner-smoothing mechanism is arranged in the tape rolling mechanism frame, and a secondary corner-smoothing mechanism is arranged at the front end along the carton transportation direction; the tape rolling mechanism is used to seal the vertical surface of the carton corner, and a tape smoothing mechanism for the horizontal surface of the carton corner is also arranged at the front end of the secondary corner-smoothing mechanism along the carton transportation direction;

[0008] Furthermore, the tape roller mechanism comprises: a tensioning wheel for tensioning the tape, a fixing wheel for fixing the tape, a first adhesive wheel, a second adhesive wheel, a first connecting rod, a second connecting rod and a spring; the tape roller mechanism is sequentially divided into an inlet end and an outlet end along the carton transport direction, a first adhesive wheel is arranged near the inlet end, the first adhesive wheel is connected to the spring through the first connecting rod, a second adhesive wheel is arranged near the outlet end, the second adhesive wheel is connected to the spring through the second connecting rod; a cutting knife is also arranged on the first connecting rod; the first connecting rod and the second connecting rod swing synchronously, thereby driving the first adhesive wheel, the second adhesive wheel and the cutting knife on the first connecting rod to swing simultaneously;

[0009] Furthermore, the cutting knife is located in the area between the first connecting rod and the second connecting rod; when in use, the swing direction of the first connecting rod is the same as the carton transportation direction, and the swing direction of the second connecting rod is opposite to the carton transportation direction;

[0010] In the tape rolling mechanism of the present invention, the winding and tensioning forms of the tape on the tensioning wheel, the fixed wheel, and the first adhesive wheel are similar to the principles and structures of the corresponding parts in the existing CN 206087512 U patent; the tape head of the tape roll passes through the tensioning wheel, the fixed wheel, and the first adhesive wheel in sequence according to the rotation direction of each wheel, and after the end of the tape passes through the first adhesive wheel, the non-adhesive surface of the tape needs to contact the surface of the first adhesive wheel, and the adhesive surface of the tape faces the vertical surface of the corner of the carton; when in use, the front end of the carton first contacts the first adhesive wheel, and as the carton moves forward, the tape is pulled longer and longer, so that the adhesive surface of the tape gradually fits the vertical surface of the corner of the carton;

[0011] The upper part of the tape attached to the vertical surface of the carton corner extends a portion of the height of the upper edge of the vertical surface. This part of the tape is suspended vertically, which is called the suspended vertical area of ​​the tape. The lower part of the tape is completely attached to the vertical surface.

[0012] During the above-mentioned carton movement, the front end of the carton first contacts the first glue wheel, and at this time the carton rolls the first glue wheel to retract into the roller mechanism frame. Due to the setting of the connecting rod, the second glue wheel and the cutting knife are synchronously driven to retract together, and the spring is in a compressed state at this time; as the carton moves along the transport direction to the position where the carton is separated from the second glue wheel, the spring stretches, and the second glue wheel rebounds outwards, and synchronously, the first glue wheel and the cutting knife also rebound outwards, and at this time the cutting knife cuts the tape;

[0013] Furthermore, when the carton moves along the transport direction, the tape head at the front end of the carton needs to pass through the first corner-smoothing mechanism; the first corner-smoothing mechanism includes: a connecting rod, one end of which is fastened to the upper plane plate of the roller mechanism frame by bolts, and the other end of which extends toward the direction of the carton and is fixed by bolts to a rubber soft plate extending downward; when in use, the carton with the tape head attached moves forward, the carton touches the rubber soft plate of the first corner-smoothing mechanism and passes through, and the tape head is smoothed at the front end of the carton through the rubber soft plate, so that the tape head is attached to the corner of the front end of the carton;

[0014] The front end of the carton is smoothed and continues to move forward, and the tape suspended above the vertical surface of the carton corner continues to remain in an upright state and passes through the first smoothing mechanism. Due to the cutting of the cutting knife, the tail end of the carton has a tape tail, and the tape tail at the tail end of the carton needs to be smoothed by the second smoothing mechanism.

[0015] Furthermore, the second corner-smoothing mechanism comprises: a rotating plate, a motor and a bolt; the second corner-smoothing machine is arranged above the running height of the carton, and a rotating plate is fixedly arranged at the end of the output shaft of the motor; when in use, the rotating plate at the end of the shaft is driven to rotate clockwise by the rotation of the motor shaft, and when the carton runs through the position of the rotating plate, the rotating plate is swung by starting the motor, so that the tail of the tape at the rear end of the carton is smoothed, so that the tail of the tape is attached to the corner of the rear end of the carton;

[0016] Furthermore, the rotation direction of the rotating plate is the same as the direction of carton transportation;

[0017] After the front and rear ends of the above-mentioned carton have been smoothed, they continue to move forward. At this time, the adhesive tape in the suspended upright state above the vertical surface of the carton corner continues to remain in an upright state, and reaches the position of the adhesive tape smoothing mechanism on the horizontal surface of the carton corner. It is necessary to smooth the adhesive tape in the suspended upright state above the vertical surface of the carton corner on the horizontal surface of the carton corner;

[0018] The tape smoothing mechanism comprises: a cylinder, a brush and a brush moving plate; the tape smoothing mechanism is arranged above the running height of the carton, and the brush head can touch the upper plane of the carton; the brush comprises a brush handle and bristles, the telescopic end of the cylinder is fixedly connected to the brush handle, the upper surface of the brush handle is slidably connected to the brush moving plate by a slide, and the bristles are arranged vertically downward toward the upper plane of the carton;

[0019] Furthermore, the sliding direction of the brush on the brush moving plate is perpendicular to the transportation direction of the carton.

[0020] When the above-mentioned tape smoothing mechanism is in use, the carton moves to the front end position of the second corner smoothing mechanism and stays there. By starting the cylinder, the telescopic rod of the cylinder pushes the brush to move from the outside to the inside, and then the bristles of the brush are brushed on the flat surface of the carton, thereby smoothing the suspended vertical tape above the vertical surface of the carton corner to the flat surface of the carton; thereby completing the tape packaging of the entire edge of the carton.

[0021] Furthermore, in the packaging mechanism of the present scheme, the second corner smoothing mechanism and the tape smoothing mechanism are arranged on the upper frame; the motor flange in the second corner smoothing mechanism is fixedly connected to the frame by bolts, and the brush moving plate in the tape smoothing mechanism is fixed to the frame by bolts.

[0022] The beneficial effects of the flip-top carton tape packaging and packaging mechanism are:

[0023] By setting up a tape roller mechanism and utilizing the adhesiveness of the tape itself, the starting end of the carton is bonded to the tape as the starting point of the entire sealing process. The carton is operated to move, and the tape roll is driven to complete the gluing by itself, thereby realizing the tape sealing of the edges of the carton. At the same time, by setting up a two-level corner-smoothing mechanism, the corners of the tape heads at the starting and ending ends of the carton can be smoothed, thereby completing the sealing of the entire edge. The mechanism adopts automated operation and does not require manual work, thereby improving packaging efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The cutting knife 12 is located in the area between the first connecting rod 10 and the second connecting rod 11; when in use, the swing direction of the first connecting rod 10 is the same as the carton transportation direction, and the swing direction of the second connecting rod 11 is opposite to the carton transportation direction;

[0044] In the tape rolling mechanism, the tape head of the tape roll 3 passes through the tension wheel 6, the fixed wheel 7 and the first adhesive wheel 8 in turn according to the rotation direction of each wheel. After the end of the tape passes through the first adhesive wheel 8, the non-adhesive surface of the tape needs to contact the surface of the first adhesive wheel 8, and the adhesive surface 5 of the tape faces the vertical surface of the corner of the carton. When in use, the front end of the carton first contacts the first adhesive wheel 8. As the carton moves forward, the tape is pulled longer and longer, so that the adhesive surface 5 of the tape gradually fits the vertical surface of the corner of the carton.

[0045] The upper part of the adhesive tape attached to the vertical surface of the carton corner extends a portion of the height of the upper edge of the vertical surface, and this part of the adhesive tape is in a suspended vertical state, which is called the suspended vertical area 13 of the adhesive tape. Figure 4 , 5 , 7, 10 and 11, the lower part of the tape is completely attached to the vertical surface;

[0046] During the above-mentioned carton movement, the front end of the carton first contacts the first glue wheel 8, and at this time, the carton rolls the first glue wheel 8 to retract into the roller mechanism frame 1. Due to the setting of the connecting rod, the second glue wheel 9 and the cutting knife 12 are synchronously driven to retract together, and the spring is in a compressed state at this time; as the carton moves along the transport direction to the position where the carton is separated from the second glue wheel 9, the spring stretches, and the second glue wheel 9 rebounds outwards, and synchronously, the first glue wheel 8 and the cutting knife 12 also rebound outwards, and at this time the cutting knife 12 cuts the tape;

[0047] When the carton moves along the transport direction, the tape head at the front end of the carton needs to pass through the first corner-smoothing mechanism; the first corner-smoothing mechanism includes: a connecting rod 14, one end of the connecting rod 14 is fastened to the upper plane plate of the roller mechanism frame 1 by bolts, and the other end extends in the direction of the carton and is fixed by bolts to a rubber soft board 15 extending downward; when in use, the carton with the tape head attached moves forward, the carton touches the rubber soft board 15 of the first corner-smoothing mechanism and passes through, and the tape head is smoothed at the front end of the carton through the rubber soft board 15, so that the tape head is attached to the corner of the front end of the carton;

[0048] The front end of the carton is smoothed and continues to move forward, and the tape suspended above the vertical surface of the carton corner continues to remain in an upright state and passes through the first smoothing mechanism. Due to the cutting of the cutting knife 12, the tail end of the carton has a tape tail, and the tape tail at the tail end of the carton needs to be smoothed by the second smoothing mechanism.

[0049] The second corner-smoothing mechanism comprises: a rotating plate 16, a motor 17 and a bolt 18; the second corner-smoothing machine is arranged above the running height of the carton, and the rotating plate 16 is fixedly arranged at the end of the output shaft of the motor 17; when in use, the rotating plate 16 at the end of the shaft is driven to rotate clockwise by the rotation of the motor shaft, and when the carton runs through the position of the rotating plate 16, the rotating plate 16 is swung by starting the motor 17, so that the tail of the tape at the rear end of the carton is smoothed, so that the tail of the tape is attached to the corner of the rear end of the carton;

[0050] After the front and rear ends of the above-mentioned carton have been smoothed, they continue to move forward. At this time, the adhesive tape in the suspended upright state above the vertical surface of the carton corner continues to remain in an upright state, and reaches the position of the adhesive tape smoothing mechanism on the horizontal surface of the carton corner. It is necessary to smooth the adhesive tape in the suspended upright state above the vertical surface of the carton corner on the horizontal surface of the carton corner;

[0051] The tape smoothing mechanism comprises: a cylinder 19, a brush and a brush moving plate 22; the tape smoothing mechanism is arranged above the running height of the carton, and the brush head can touch the upper plane of the carton; the brush comprises a brush handle 20 and bristles 21, the telescopic end of the cylinder 19 is fixedly connected to the brush handle 20, the upper surface of the brush handle 20 is slidably connected to the brush moving plate 22 by a slide, and the bristles 21 are arranged vertically downward toward the upper plane of the carton;

[0052] When the above-mentioned tape smoothing mechanism is in use, the carton moves to the front end position of the second corner smoothing mechanism and stays there. By starting the cylinder 19, the telescopic rod of the cylinder 19 pushes the brush to move from the outside to the inside, and then the bristles 21 of the brush are brushed on the flat surface of the carton, thereby smoothing the suspended vertical tape above the vertical surface of the carton corner to the flat surface of the carton; thereby completing the tape packaging of the entire edge of the carton.
