[0002] The handheld transparent tape cutter is a tool for cutting transparent tape, and has a simple structure. It mainly cuts the transparent tape through cutting teeth, and is widely used in various packaging fields. The handheld transparent tape cutter is small in size, has a good use effect, and can quickly cut the tape, which is faster than cutting with a knife.

[0003] When using an existing handheld transparent tape cutter, the tape is attached to the surface of an object such as a carton. The tape needs to be cut first, and then the surface of the tape needs to be pressed and smoothed by hand in a certain direction to discharge the bubbles between the tape and the surface of the carton and other objects, so that the tape and the surface of the carton and other objects can be fully bonded. However, this operation is time-consuming and inconvenient, which seriously affects the operating efficiency. In addition, the cutting blade of an ordinary transparent tape cutter is always exposed to the outside. When pulling the tape, it is easy to cause the cutting blade to scratch the hand if not careful. When placed normally, the cutting blade is exposed to the outside and is also more likely to scratch other objects.

[0025] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0026] like Figure 1 to Figure 6-2 As shown, the handheld tape roller cutter includes a handle 1, a tape mounting seat 2 is provided on the handle 1, a mounting plate 3 is provided at one end of the handle 1, a cutting blade 4 is provided at the upper end of the mounting plate 3, a bracket 5 is movably connected to the mounting plate 3, and a pressure roller 6 is rotatably connected to the end of the bracket 5.

[0027] The tape cutter includes a hand-held part, a cutting part and a rolling part. The handle 1 is used as the hand-held end of the operator. The end of the handle 1 has an arc-shaped transition, which makes it more convenient for the operator to hold the handle. The tape mounting seat 2 is used for installing the tape sleeve. The mounting plate 3 is used for installing the cutting blade 4 and the bracket 5. The bracket 5 is hinged on the mounting plate 3 and can rotate around the mounting plate 3. The pressure roller 6 can discharge the bubbles between the tape and the surface of the object to improve the bonding effect. The cutting blade 4 is arranged at the front end of the mounting plate 3. The pressure roller 6 bracket 5 is located at the front end of the mounting plate 3 and the upper part of the cutting piece. It is connected to the two sides of the mounting plate 3 through two connecting shafts 7. The pressure roller 6 is arranged at the front end of the rubber roller bracket 5 and the front part of the cutting blade 4. It is connected to the pressure roller 6 bracket 5 through a rotating shaft 9.

[0028] like Figure 3 As shown, a connecting shaft 7 is provided at one end of the bracket 5, a connecting hole 8 is provided at the side of the mounting plate 3, and the connecting shaft 7 extends into the connecting hole 8; a rotating shaft 9 is provided at the other end of the bracket 5, and a pressure roller 6 is arranged on the rotating shaft 9. The above structure enables the bracket 5 to have a rotating function, and the bracket 5 is easy to install. The bracket 5 can be manufactured independently, and even if the bracket 5 is damaged, it can be quickly replaced. The pressure roller 6 is located in front of the cutting blade 4, and the rotating shaft 9 is flush with the cutting blade 4.

[0029] like Figure 3 and Figure 5As shown, a torsion spring 10 is provided on the connecting shaft 7, and the torsion spring 10 is located between the mounting plate 3 and the end of the bracket 5, with one end of the torsion spring 10 extending into the bracket 5, and the other end extending into the mounting plate 3. The torsion spring 10 has a torsion force that can resist the downward pressure of the hand, so that when the pressure roller 6 and the bracket 5 are pressed down, the adhesive tape contacts the cutting blade 4 and is cut. At the same time, the torsion spring 10 also constrains the rotation angle of the bracket 5. When the adhesive tape is at the turning point of the carton or is bonded in the vertical direction, when it is necessary to cut the adhesive tape, under the elastic reset action of the torsion spring 10, only the handle 1 needs to be rotated a certain angle, and the adhesive tape can be cut by the cutting blade 4. After the bonding is completed, the torsion spring 10 can realize the automatic reset of the bracket 5 after rotation.

[0030] like Figure 1 As shown, the middle part of the bracket 5 is located above the cutting blade 4. When placed normally, the space above the cutting blade 4 is blocked by the bracket 5, which prevents the cutting blade 4 from being exposed to the outside, and the operator's hand will not touch the cutting blade 4, nor will it scratch other objects.

[0031] like Figure 2 and Figure 4 As shown, the cutting blade 4 is a groove structure, and the cutting blade 4 is clamped on the upper end of the mounting plate 3. With the above structure, when the cutting blade 4 is replaced, the purpose of rapid installation can be achieved. In order to further improve the stability of the cutting blade 4, rivets can be used to fix it.

[0032] like Figure 2 As shown, the end of the cutting blade 4 is a sawtooth structure. The sawtooth cutting blade 4 generates greater pressure on the tape, and the tape can be cut quickly by the pressure of the hand, and the fracture of the tape is also more flush, and the appearance of the tape packaging is better.

[0033] like Figure 2 As shown, a stopper 12 is provided on the mounting plate 3, and the stopper 12 is located below the cutting blade 4. Before bonding, the stopper 12 can initially place the free end of the tape to prevent it from falling back, avoiding the free end of the tape from being bonded back to the tape or other positions due to gravity, causing inconvenience in use.

[0034] like Figure 1 and Figure 4 As shown, a limit plate 13 is provided at one end of the tape mounting seat 2, and a limit pin 11 is provided at the end of the connecting shaft 7. In order to prevent the tape from being unstable due to rotation during use, the limit plate 13 is provided to limit the tape, thereby stabilizing the axial position of the tape, and the tape will not shake too much when rotating, ensuring the smoothness of the tape bonding process. The limit pin 11 is used to prevent the bracket 5 from loosening from the mounting plate 3 after installation.

[0035] The material of the pressure roller 6 is EPDM, silicone rubber, chloroprene rubber, styrene-butadiene rubber or nitrile rubber. The pressure roller 6 made of the above materials has an antistatic function and will not introduce bubbles into the adhesive tape due to static adsorption.

[0036] like Figure 6-1 and Figure 6-2 As shown, the implementation process is as follows: first, the free end of the tape is bonded to the surface of an object such as a carton, and the bracket 5 is pressed downward by the torsion spring 10. The bracket 5 rotates a certain angle, thereby driving the pressure roller 6 to press downward, and the tape cutter is held and moved along the bonding direction. When the tape is bonded, the pressure roller 6 applies rolling pressure to the tape bonded to the surface of the object. As the tape cutter moves, the pressure roller 6 is driven to roll and crush the tape, so that the bubbles between the tape and the surface of the object are discharged and no static electricity is generated, so that the tape and the surface of the object are fully bonded, and the tape is also quickly bonded. When it is necessary to cut the tape, lift the handle 1, and the bracket 5 rotates along the connecting shaft 7 as a whole, so that the cutting blade 4 moves downward obliquely relative to each other. Under the action of the torsion spring 10, the tape is blocked by the end of the cutting blade 4 and cut. When the tape is turned at the end of the carton and bonded in the vertical direction, if it is necessary to cut the tape, it is only necessary to lift the handle 1 and rotate it a certain angle relative to the bracket 5, so that the tape can be cut when it contacts the cutting blade 4. In addition, when applying the tape, the bracket 5 is located above the cutting blade 4, and the pressure roller 6 blocks the cutting teeth at the front of the cutting part, so that the cutting blade 4 will not scratch the fingers.

[0037] The hand-held tape roller cutter, by adding a movable bracket 5 and a rotatable pressure roller 6, can effectively discharge bubbles between the tape and the surface of the object by rolling the adhesive tape with the pressure roller 6, thereby improving the uniform bonding effect of the tape and achieving the effect of full bonding, replacing the time-consuming and laborious operation mode of manual smoothing, and improving the operation efficiency. When in use, the tape can be quickly cut by rotating the handle 1 by relying on the action of the torsion spring, and the use process is more convenient; and the setting of the bracket 5 also avoids the exposure of the cutting blade 4, protecting the operator's hands or other parts from being scratched, and the use is safer.

[0038] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
