The tape dispenser may be a single-sided tape dispenser or a double-sided tape dispenser, depending on the properties of the tape. For double-sided tape stickers, the most popular products in the market are to apply a non-setting adhesive on a substrate, and to roll the substrate back when in use, so that the glue on the substrate can be left on the adhered object. However, the adhesive layer formed by the glue is very thin, resulting in low strength and poor adhesion of the adhesive layer, for example, when the glue is adhered to paper, the paper can tear the adhesive layer as soon as it is torn, thereby causing great limitations to the field of use of the double-sided tape applicator, which can only be used for manual labor with low requirements for viscosity, but cannot be used well in many fields. Meanwhile, the glue used can only be low-viscosity self-adhesive glue, and the service life of the glue adhesion is short due to the fact that the base material needs to be peeled off, and the application of the glue on the industry is also greatly limited. In addition, some adhesive tape cutters are available in the market, after the double-sided adhesive tape in the adhesive tape cutter is pulled out and cut, a user needs to peel off the separation paper on two sides or one side of the double-sided adhesive tape by hands, the operation is time-consuming and labor-consuming, and the adhesive tape cutter is very inconvenient and is not convenient for adhering the double-sided adhesive tape to an adhered object.

As shown in fig. 1 to 4, the single-sided and double-sided tape applicator includes a housing 20, a tape roll 10, a cutting unit 30, a movable pounding head 40, a gear bracket 50, a pressing wheel 60, and a first driven wheel 70. Wherein, the upper end portion of the housing 20 is provided with a tape mounting cavity, and the tape roll 10 is rotatably mounted in the tape mounting cavity; the tape roll 10 may be a tape roll 10 on which a single-sided tape is wound, or a tape roll 10 on which a double-sided tape is wound, so that the single-sided and double-sided tape applicator can be used for both adhesion of the single-sided tape and adhesion of the double-sided tape; in the following embodiments, a single-sided tape and a double-sided tape are collectively referred to as tapes, and the tapes are wound around the tape roll 10. The front of casing 20 has seted up installation space 21, and sticky tape export 22 is seted up to the bottom of casing 20, and the upper and lower both ends of installation space 21 extend to sticky tape installation cavity and sticky tape export 22 respectively. The right end of the movable tamper head 40 is rotatably mounted at the right lower end of the housing 20, and the right end of the movable tamper head 40 can be turned over up and down around a first fixed axis S1 extending back and forth; the gear bracket 50 is positioned at the left side of the movable tamping head 40, the gear bracket 50 is rotatably arranged in the shell 20, and the gear bracket 50 can be turned over up and down around a second fixed axis S2 extending back and forth; the movable tamping head 40 is in transmission connection with the gear bracket 50. The front surface of the gear bracket 50 is provided with a belt passing channel 51 for allowing the adhesive belt to pass through, the pressing wheel 60 and the first driven wheel 70 are both rotatably mounted on the gear bracket 50, the pressing wheel 60 and the first driven wheel 70 are both gears and are meshed with each other, and an entrainment gap is formed between the pressing wheel 60 and the first driven wheel 70 and is exposed out of the belt passing channel 51. The cutting unit 30 comprises a reciprocatable cutting blade 31, which cutting blade 31 can be brought closer to or further away from the length of adhesive tape projecting downwards from the entrainment gap. In this embodiment, the rotation axis of the first driven wheel 70 and the rotation axis of the gear bracket 50 are the same axis and are distributed on the right side of the entrainment gap, and the pressing wheel 60 is distributed on the left side of the entrainment gap; alternatively, the first driven pulley 70 is rotatably mounted to the right lower end of the gear bracket 50, the pressing wheel 60 is rotatably mounted to the left lower end of the gear bracket 50, and the right lower end of the gear bracket 50 is rotatably mounted to the housing 20.

When the movable tamping head 40 is not stressed, the movable tamping head 40 is at the lower limit position in the swing range, which is also the initial state of the single-sided and double-sided tape applicator, i.e. the idle state when the single-sided and double-sided tape applicator is not used, at this time, as shown in fig. 7 and 8, the tape passing channel 51 on the gear bracket 50 is in a crossed position relation with the installation gap 21 on the front surface of the housing 20, and the pressing and pasting wheel 60 is entirely positioned in the housing 20. When the adhesive tape roll 10 needs to be loaded into the adhesive tape loading cavity of the housing 20, an upward acting force is applied to the movable tamper head 40, so that the movable tamper head 40 rotates upward around the first fixed axis S1, and when the movable tamper head 40 rotates clockwise around the first fixed axis S1 as viewed in the view of fig. 7, the movable tamper head 40 drives the gear bracket 50 to rotate counterclockwise around the second fixed axis S2, so as to change the position of the tape passing channel 51 on the front surface of the gear bracket 50, so that the extending direction of the tape passing channel 51 is substantially consistent with the extending direction of the mounting gap 21, and the tape passing channel 51 is completely exposed from the mounting gap 21, as shown in fig. 5 and 6, at this time, the single-sided adhesive tape or double-sided adhesive tape at the head of the adhesive tape roll 10 can be conveniently loaded into the tape passing channel 51 of the gear bracket 50 and the clamping gap between the pressing wheel 60 and the first driven wheel 70, and the operation is very convenient. After the adhesive tape roll 10 is mounted, the movable tamping head 40 is loosened, the movable tamping head 40 rotates downwards and resets, and the movable tamping head 40 drives the gear bracket 50 to reset to the state of fig. 7 and 8; in the process, the pressing wheel 60 is turned upwards, so that the head of the adhesive tape in the clamping gap is driven to move upwards, the head of the adhesive tape is not exposed out of the adhesive tape outlet 22 of the shell 20, and the adhesive tape is prevented from being adhered accidentally. Then, the single-sided and double-sided tape sticking device can be normally used: firstly, when in use, the movable tamping head 40 is pressed upwards, an upward acting force is applied to the movable tamping head 40, so that the movable tamping head 40 rotates upwards around a first fixed axis S1, and the movable tamping head 40 drives the gear bracket 50 to rotate anticlockwise around a second fixed axis S2; in the process, the pressing wheel 60 is turned downwards to enable the lower end of the pressing wheel to be exposed downwards from the adhesive tape outlet 22 at the bottom of the shell 20, the pressing wheel 60 drives the head of the adhesive tape in the entrainment gap to move downwards, as shown in fig. 5 and 6, so that the head of the adhesive tape is sent out from the adhesive tape outlet 22, the automatic adhesive tape feeding is realized, and the head of the adhesive tape is conveniently adhered to an adhered object; secondly, the single-sided and double-sided adhesive tape sticking device is translated rightwards, the adhesive tape is continuously pulled out, and meanwhile, the lower end of the pressing and sticking wheel 60 continuously sticks the adhesive tape on the stuck object; thirdly, after each bonding, the movable tamping head 40 is loosened, the movable tamping head 40 rotates downwards and resets, as shown in fig. 7 and 8, the pressing wheel 60 drives the head of the adhesive tape in the clamping gap to move upwards, so that the section of the adhesive tape extending downwards from the clamping gap is exposed on the motion path of the cutting blade 31, and the cutting blade 31 moves towards the direction close to the section of the adhesive tape to cut the adhesive tape; the cut tape is still clamped in the clamping gap between the pressing wheel 60 and the first driven wheel 70, and the head part still extends downwards from the clamping gap, but the head part of the tape is completely accommodated in the casing 20 and is not exposed from the tape outlet 22 of the casing 20. Therefore, the adhesive tape feeding device can automatically feed the adhesive tape, continuously output the adhesive tape, adhere the adhesive tape to an adhered object and cut the adhesive tape after the adhesion is finished, and the adhesive tape and the whole base material of the adhesive tape are adhered to the adhered object, so that the adhesive tape has very good strength and viscosity, is firm in adhesion, can be well used in industry, has wide application field and is not limited to be used in manual labor any more.

Further, the single-sided and double-sided tape sticking device further comprises a torsion spring installed in the casing 20, the torsion spring is installed at the first fixed axis S1 of the movable tamping head 40, two ends of the torsion spring are respectively connected with the casing 20 and the movable tamping head 40, and the torsion spring applies downward rotating acting force to the movable tamping head 40. Thus, when the movable tamper head 40 is not stressed, the movable tamper head 40 is kept at the lower limit position in the swing range thereof under the action of the torsion spring, and the spring force of the torsion spring drives the movable tamper head 40 to move downwards and reset.
