Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 3 to 7, the adhesive tape cutter includes a housing 1, and an adhesive tape shaft 2, an adhesive plate 3 and a cutting strip 4 which are arranged in the same direction, wherein the adhesive tape shaft 2 is detachably connected with the housing 1, the adhesive plate 3 is located in front of the adhesive tape shaft 2 and connected with the housing 1, and the cutting strip 4 is connected with the housing 1; the middle shaft 5 is arranged in the same direction as the adhesive tape shaft 2, and the middle shaft 5 is positioned between the adhesive tape shaft 2 and the adhesive plate 3; the cutting strip 4 is positioned at the front upper part of the pasting plate 3, the cutting strip 4 comprises a beam 41 and a cutting edge 42 positioned below the beam 41, and the cutting edge 42 does not exceed the front edge of the beam 41; the intermediate shaft 5 is close to the attachment plate 3 so that the adhesive tape that has passed around the intermediate shaft 5 from below the intermediate shaft 5 can be dropped onto the attachment plate 3 and the attachment plate 3 is exposed.

As shown in fig. 4 and 6, since the cutting strip 4 is located at the front upper part of the adhesive plate 3 and the middle shaft 5 is located at the rear part of the adhesive plate 3 and close to the adhesive plate 3, the distance a between the cutting edge 42 and the lower edge of the middle shaft 5 is much greater than the distance b between the front edge of the adhesive plate 3 and the lower edge of the middle shaft 5, so that the adhesive tape 81 passing around the middle shaft 5 from the lower part of the middle shaft 5 can fall onto the adhesive plate 3 and expose the adhesive plate 3. The utility model discloses during the use, directly draw and expose the sticky tape 81 of pasting board 3, then move up sticky tape 81, cut off sword 42 and can cut off sticky tape 81. After the tape 81 is cut, as shown in fig. 7, the tape is dropped onto the attachment plate 3 to expose the attachment plate 3, so that the tape 81 can be pulled out at the next time.

The cutting blade 42 is located below the beam 41 and does not go beyond the front edge of the beam 41, and the cutting blade 42 is not easily touched by the beam 41, so that the cutting blade 42 is not easily hurt people during non-cutting operation. When the tape 81 is pulled out, as shown in fig. 7, the tape 81 hangs down in front of the attachment plate 3, and the tape 81 is distant from the cutting blade 42, so that the cutting blade 42 is also less likely to injure a person during the cutting operation.

The distance b between the front edge of the pasting board 3 and the lower edge of the intermediate shaft 5 can be shortened by the intermediate shaft 5 being close to the pasting board 3, so that the length of the adhesive tape 81 exposed out of the pasting board 3 can be increased. Preferably, the lower edge of the intermediate shaft 5 is flush with the surface of the adhesive plate 3. The intermediate shaft 5 can be mounted through the housing 1, with a flange at one end of the intermediate shaft 5 and a nut 6 at the other end to achieve axial positioning. When the adhesive tape roll 8 is installed, the adhesive tape shaft 2 needs to be pulled outwards; then the adhesive tape roll 8 is put in and the adhesive tape roll 8 is sleeved on the adhesive tape shaft 2; then the adhesive tape shaft 2 is installed back; the adhesive tape 81 is then pulled out to the front of the attachment plate 3. Therefore, the distance between the middle shaft 5 and the pasting plate 3 should ensure that the adhesive tape 81 can pass through smoothly, and the adhesive tape 81 can be conveniently pulled out in the process. The height of the cutting edge 42 should not be too large to ensure safety, and preferably not more than 5 mm.

Since the tape 81 is in contact with the intermediate shaft 5 on the back side (non-adhesive side), the intermediate shaft 5 has little resistance to the tape 81 being pulled out. In order to further reduce the pulling-out resistance of the adhesive tape 81, it may be preferable that the intermediate shaft 5 be rotatable. The axial positioning of the tape shaft 5 can be realized by arranging the shaft neck 51 on the tape shaft 5 and inserting the shaft neck into the hole of the shell 1, and the tape shaft 5 can rotate.

The tape 81 is not generally stuck to the cutting blade 42 and does not fall off. However, in order to further prevent the tape 81 from sticking to the cutting edge 42, it is preferable that the intermediate shaft 5 be able to move upward. When the tape 81 is cut, the tape 81 moves upward, so that the intermediate shaft 5 is driven by the tape 81 to move upward, and after the tape 81 is cut, the intermediate shaft 5 moves downward due to gravity to press the tape 81 downward, thereby ensuring that the tape 81 does not stick to the cutting blade 42. The housing 1 is provided with an elongated hole 11, and the intermediate shaft 5 can be rotated and moved upward by inserting the journal 51 into the elongated hole 11.

In order to prevent the adhesive tape 81 from being contaminated, it is preferable that the adhesive tape cutter includes a cartridge cover 7, and the cartridge cover 7 is covered on the case 1. The lid 7 is closed to prevent the tape 81 from being contaminated, and the lid 7 is opened to mount the tape roll 8. Since the adhesive tape 81 is not pulled out from above the housing 1, the tape 81 cutting operation is not affected by the lid 7, and the cutting can be performed without opening the lid 7.
