Description

Technical Field

[0001] The invention relates to the technical field of packaging and box sealing, in particular to a box sealing device anti-adhesive tape curling structure. Background Art

[0002] The carton sealer allows the tape to rotate freely and features a hidden blade for easy tape cutting when needed. The tape outlet of the carton sealer features a pressure plate that guides the tape and provides support during cutting. However, with existing carton sealers, the tape tends to rewind after being pressed, making it difficult to retrieve the tape for the next use, which is inconvenient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a carton sealer anti-tape curling structure in which, after the tape pressing plate presses the tape, the plate has a convex shape to press the tape, causing the tape to bend in the cross section, thereby achieving the effect of being difficult to rewind and easy to pick up.

[0004] The technical solution of the present invention is to provide a carton sealer anti-tape curling structure with the following structure, including a carton sealer provided with cutting teeth, two inner side walls of the carton sealer opening are respectively provided with supporting blocks, and a tape pressing plate is provided at the opening of the carton sealer; the outer end of the tape pressing plate is a free end and passes through a plane formed by the upper end surfaces of the two supporting blocks, and the tape passes through the plane and abuts against the free end of the tape pressing plate to generate a bend in the cross section.

[0005] The pressing tape plate is a lever, the fulcrum of which is rotatably connected to the two inner sides of the opening of the carton sealer; the outer end of the pressing tape plate is a power arm, which is located on the outer side of the opening and is in contact with the two supporting blocks on the inner side of the opening of the carton sealer; the inner end of the pressing tape plate is a resistance arm, which is located on the inner side of the opening and is provided with an elastic element, one end of which is in contact with the inner side of the carton sealer; a protrusion is provided at the outer end of the pressing tape plate; the adhesive tape passes between the power arm of the pressing tape plate and the two supporting blocks and is bent by contact with the protrusion.

[0006] The pressing tape plate is an elastic element, the inner end of which is fixed to the inner side of the carton sealer opening, and the two sides of the outer end of the pressing tape plate extend to the two supporting blocks to form a channel for the tape to pass through. A protrusion is provided in the middle part of the outer end of the pressing tape plate, and the tape passes between the two sides of the pressing tape plate and the two supporting blocks and bends against the protrusions.

[0007] The inner end of the elastic element is fixed to the inner side of the carton sealer opening. There is a distance between both sides of the elastic element and the support blocks on the same side. The tape passes through the upper planes of the two support blocks and bends against the protrusions.

[0008] The fulcrum is rotatably connected to the two inner sides of the opening of the carton sealer, which means that the two side walls of the pressing tape plate are respectively provided with pins, and are movably embedded in the corresponding holes on the inner side of the carton sealer. The pins on both sides are coaxial and serve as the central axis of rotation for the swing of the pressing tape plate.

[0009] The inner end of the adhesive tape plate is provided with two flat surfaces which are respectively in contact with the supporting blocks under the elastic force of the elastic element.

[0010] The protrusion is in an arc shape.

[0011] The fixed end of the adhesive tape plate is connected to the inner side wall of the carton sealer and forms an integrated structure.

[0012] After adopting the above structure, the present invention has the following advantages: the outer end of the pressing tape plate is a free end and passes through the plane formed by the upper end surfaces of the two supporting blocks, that is, the free end is convex, so that after the tape is cut, it can be squeezed by the free end of the pressing tape plate, and a bend is generated in the cross section, that is, it becomes an arched structure, so that the tape is not easy to rewind in the extending direction, and it is straight and exposed to the carton sealer, which is convenient for picking up.

[0013] The pressing tape plate is a lever, the fulcrum of which is rotatably connected to the two inner sides of the opening of the carton sealer; the outer end of the pressing tape plate is a power arm, which is located on the outer side of the opening and is in contact with the two supporting blocks on the inner side of the opening of the carton sealer; the inner end of the pressing tape plate is a resistance arm, which is located on the inner side of the opening and is provided with an elastic element, one end of which is in contact with the inner side of the carton sealer; a protrusion is provided at the outer end of the pressing tape plate; the tape passes between the power arm of the pressing tape plate and the two supporting blocks and is bent by contact with the protrusion. Through the swing of the lever and the elastic support of the elastic element at the inner end of the pressing tape plate, the protrusion can always be in contact with the tape after the tape is cut, and the structure is reliable.

[0014] The pressing tape plate is an elastic element, the inner end of which is fixed to the inner side of the carton sealer opening, and the two sides of the outer end of the pressing tape plate extend to the two supporting blocks to form a channel for the tape to pass through. A protrusion is provided in the middle part of the outer end of the pressing tape plate, and the tape passes between the two sides of the pressing tape plate and the two supporting blocks and bends against the protrusions, so that the two sides of the tape are supported by the supporting blocks and the middle is pushed out by the protrusion, which can ensure that the tape is pushed into an arch shape.

[0015] The inner end of the elastic element is fixed to the inner side of the opening of the carton sealer, and a distance is set between both sides of the elastic element and the supporting blocks on the same side. The tape passes through the upper planes of the two supporting blocks and bends against the protrusions, so that after the tape is cut, the middle part is pushed into an arch shape by the protrusions.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Example 1: Figure 1-3As shown, the anti-tape curling structure of the carton sealer of the present invention includes a carton sealer 1 equipped with cutting teeth 6. A whole roll of tape is embedded in the carton sealer 1. The center hole of the tape is embedded with the positioning axis of the carton sealer 1, and can rotate freely in the circumferential direction when the tape is pulled. The opening of the carton sealer 1 is provided with a tape pressing plate 2. The tape pressing plate 2 is a lever with a fulcrum connected to the two inner sides of the opening of the carton sealer 1. The outer end of the tape pressing plate 2 is a power arm, located outside the opening and abutting against two supporting blocks 3 inside the opening of the carton sealer 1. The inner end of the tape pressing plate 2 is a resistance arm, located inside the opening and equipped with an elastic element 4, one end of which abuts against the inner side of the carton sealer 1. The outer end of the tape pressing plate 2 is provided with a protrusion 5, which is located between the two supporting blocks 3 and the cutting teeth 6 of the carton sealer 1. The tape passes between the power arm of the tape pressing plate 2 and the two supporting blocks 3 and abuts against the protrusion 5, thereby bending. The fulcrum is rotatably connected to the two inner sides of the opening of the carton sealer 1, which means that the two side walls of the tape pressing plate 2 are respectively provided with pins 7, and are movably embedded in the corresponding holes on the inner side of the carton sealer 1. The pins 7 on both sides are coaxial and serve as the central axis of rotation for the tape pressing plate 2 to swing. The inner end of the tape pressing plate 2 is provided with two flat surfaces 8, and they are respectively attached to the support blocks 3 under the elastic force of the elastic element 4. The protrusion 5 is in an arc shape. The protrusion 5 protrudes from the bottom plane of the tape pressing plate 2, and the bottom plane of the tape pressing plate 2 forms an angle. The tape passes through the power arm of the tape pressing plate 2 and the two support blocks 3 in a planar state, and the position where the cut end of the tape abuts the protrusion 5 is provided with an end distance; the tape is positioned between the power arm of the tape pressing plate 2 and the two support blocks 3, and the tape near the end is pushed out of the bending state by the protrusion 5.

[0026] Example 2: Figure 4 and Figure 5 As shown, the anti-tape curling structure of the carton sealer of the present invention includes a carton sealer 1 equipped with cutting teeth 6. A whole roll of tape is embedded in the carton sealer 1. The center hole of the tape is embedded with the positioning axis of the carton sealer 1, and can rotate freely in the circumference when the tape is pulled. The tape pressing plate 2 is an integral structure with the carton sealer 1, relying on its own elastic rebound. The tape pressing plate 2 is an elastic element. The inner end of the tape pressing plate 2 is fixed to the inner side of the opening of the carton sealer 1. The two sides of the outer end of the tape pressing plate 2 extend to two supporting blocks 3 and form a channel for the tape to pass through. The middle part of the outer end of the tape pressing plate 2 is provided with a protrusion 5. The tape passes between the two sides of the tape pressing plate 2 and the two supporting blocks 3 and bends when it contacts the protrusion 5.

[0027] Example 3: Figure 6The present invention's anti-tape curling structure for a carton sealer includes a carton sealer 1 equipped with cutting teeth 6. A full roll of tape is embedded within the carton sealer 1, with the tape's center hole aligned with the carton sealer's positioning axis, allowing for free circumferential rotation when the tape is pulled. The tape pressing plate 2 is integral with the carton sealer 1 and relies on its own elasticity for resilience. The inner end of the tape pressing plate 2 is fixed to the inside of the carton sealer 1's opening. Both sides of the tape pressing plate 2 are spaced apart from the support blocks 3 on the same side. The tape passes along the upper surfaces of the two support blocks 3 and bends against the protrusions 5, causing it to abut against them.

[0028] The working principle of the present invention is as follows: after the tape is pulled out and cut, the tape pressing plate 2 is squeezed and rebounded, and the tape is clamped by the tape pressing plate 2 and the supporting block 3. The cross section of the tape is squeezed by the outer end of the tape pressing plate 2, causing bending, making it difficult for the tape to rewind in the extending direction, and it is straightened and exposed to the carton sealer for easy picking.
