Description

Technical Field

[0001] The present application relates to the technical field of daily necessities, and more specifically to a tape dispenser. Background Art

[0002] Adhesive tape is a tool used for gluing envelopes, packaging, or sealing boxes. To use it, the tape needs to be pulled off the tape roll and cut. However, the tape needs to be cut using tools such as scissors or a knife. Since the scissors or knife and the tape roll are two separate items and are usually stored separately, cutting the tape requires finding the scissors or knife beforehand, making this method of cutting the tape very inconvenient. Currently, tape is often cut using a tape dispenser. Existing tape dispensers include a base with a cutting blade and a shaft. The base and shaft are rotatably connected. The user places the tape roll on the shaft and, when in use, pulls the tape to the cutting blade to cut it, effectively avoiding the need for the user to fetch scissors to cut the tape. While existing technologies offer a certain degree of convenience, they still suffer from technical issues such as difficulty in assembling and disassembling the tape roll, insufficient tightening of the tape roll, the tape roll easily falling off during pulling, and difficulty controlling the length of the tape to be pulled. The stripping roller is a roller which is arranged on the roller body to pull the adhesive tape out of the adhesive tape and to feed the adhesive tape forwardly. Summary of the Invention

[0003] The technical problem to be solved by the present application is to provide a tape holder, which outputs the tape by driving the output mechanism to rotate unidirectionally through a one-way transmission mechanism, thereby simplifying the structural design, improving the transmission efficiency, and being more labor-saving in actual use.

[0004] The present application provides a tape holder, comprising a shell, a mounting portion for storing the tape provided in the shell, a first opening for outputting the tape provided in the shell, a cutter installed at the first opening, an output mechanism for conveying the tape installed between the mounting portion and the first opening, a switch movably installed on the shell, the switch being connected to a reset elastic member, a one-way transmission mechanism installed between the switch and the output mechanism, the switch being subjected to force to drive the output mechanism to rotate in one direction through the one-way transmission mechanism, and the output mechanism conveys the tape from the mounting portion to the first opening by rotating.

[0005] In this technical solution, the tape is installed in the installation part. When in use, the tape is pulled out from the first opening and cut by the cutter, so there is no need to equip additional tools such as scissors or knives, which improves the convenience of use. By installing an output mechanism for conveying the tape between the installation part and the first opening, the output mechanism conveys the tape of the installation part to the first opening by rotation, thereby improving the efficiency of pushing out the tape, making it easier for users to take the tape. In this solution, a switch is installed on the shell, and the switch and the output mechanism are linked by a one-way transmission mechanism. The one-way transmission mechanism can only drive the output mechanism to rotate in the direction of tape output. When the user applies force to the switch, the switch is subjected to force on the one-way transmission mechanism. The one-way transmission mechanism drives the output mechanism to rotate along the tape output direction, so that the tape can be delivered from the mounting portion to the first opening, and the force applied to the switch is proportional to the output length of the tape. Each time the user applies force to the switch to the maximum, the output length of the tape is the same, which is more convenient and labor-saving to use. When the user removes the force on the switch, the switch automatically resets under the action of the elastic reset member. At this time, under the action of the one-way transmission mechanism, the switch cannot drive the output mechanism to rotate in the opposite direction, which can prevent the output tape from being retracted. Each time the user applies force to the switch, a new section of tape can be output, which is more labor-saving and reliable in actual use, simplifies the structural design, and improves the transmission efficiency.

[0006] As an improvement, the one-way transmission mechanism includes a transmission gear and a one-way drive disk. The transmission gear meshes with the switch, and the one-way drive disk is connected to the output mechanism. In this technical solution, the one-way transmission mechanism is configured to mesh with the switch through the transmission gear, and the one-way transmission mechanism is configured to be linked to the output mechanism through the one-way drive disk. The switch is subjected to force to drive the transmission gear to rotate, and the transmission gear can drive the one-way drive disk to rotate synchronously. The one-way drive disk rotates to drive the output mechanism in the direction of tape output, thereby achieving tape output. The transmission structure is simple and efficient.

[0007] As an improvement, the output mechanism includes a first roller, a second roller, and a transmission belt. The first roller and the second roller are connected by a transmission belt, and the one-way drive disk is connected to the first roller. In this technical solution, the output mechanism includes a first roller and a second roller. The dual-roller structure design can extend the conveying path of the tape, making the tape conveying more stable and reliable. The first roller and the second roller are connected by a transmission belt. The transmission belt makes the first roller and the second roller rotate synchronously, improving the conveying efficiency. The transmission belt includes but is not limited to a belt and a rubber band. It has a simple structure and is conducive to improving the transmission efficiency. A one-way drive disk is set to be connected to the first roller. The one-way drive disk is driven by force to drive the first roller to rotate along the tape output direction. The transmission connection is simple and reliable.

[0008] As an improvement, the first roller is provided with a mounting groove for accommodating a one-way drive disc, the one-way drive disc being provided with a plurality of ratchets, an inner gear ring adapted to the ratchets being provided in the mounting groove, and the ratchets and the inner gear ring being elastically matched. In this technical solution, a mounting groove is provided in the first roller for mounting the one-way drive disc, and the one-way drive disc is elastically matched with the inner gear ring in the mounting groove through the ratchets. When the one-way drive disc is subjected to force and rotates in the direction of tape output, the ratchets abut against the inner gear ring to drive the first roller to rotate in the direction of tape output, thereby outputting the tape. When the one-way drive disc is subjected to force and rotates in the opposite direction to the tape output direction, the ratchets avoid the inner gear ring under the action of the elastic force, and the first roller is not subjected to the driving force, so that the output mechanism remains stationary, which can prevent the tape from being retracted. The structural design is ingenious and the transmission coordination is efficient.

[0009] As an improvement, the switch is provided with a rotating shaft, and the switch is rotatably connected to the housing via the rotating shaft, and the switch is located at the upper part of the housing. In this technical solution, the switch is provided to rotate with the housing, and the switch is a push-type switch. The switch rotates under the action of the pressing force, and the switch acts on the transmission gear through the rotation. The transmission gear is driven by the force to drive the one-way driving member to rotate synchronously, thereby driving the output mechanism to rotate to output the tape, which is labor-saving and convenient to use. In this application, the reset elastic member is preferably a torsion spring, which has a simple and reliable structure and a small size. On the other hand, in this solution, the switch is set at the upper part of the housing. When the user holds the housing for use, he can directly press the switch to achieve one-handed operation, which is more labor-saving and convenient to use, and has a better user experience. Moreover, the push-type switch is set at the upper part of the housing, which is not easy for the user to touch it by mistake, thereby avoiding waste of tape.

[0010] As an improvement, the switch is provided with an arc-shaped rack adapted to the transmission gear, and the switch meshes with the transmission gear via the arc-shaped rack. In this technical solution, by providing an arc-shaped rack on the switch, the switch meshes with the transmission gear via the arc-shaped rack. When the switch is rotated under force, the arc-shaped rack can drive the transmission gear to rotate, resulting in reliable and efficient transmission.

[0011] As an improvement, the mounting portion is rotatably mounted with a knob, which is used to apply the tape and drive the tape to rotate. The knob is rotated under force to recycle the tape. In this technical solution, the tape is stored in the mounting portion. By installing a knob on the mounting portion, the mounting portion applies the tape through the knob, and the knob can be rotated on the mounting portion to drive the tape to rotate synchronously. If too much tape is output, the user can apply force to the knob to rotate it in the direction opposite to the tape output direction. The knob drives the tape to rotate and recycle the tape, avoiding tape waste and meeting more usage needs.

[0012] As an improvement, the housing is provided with a second opening adapted for the knob, and the knob is exposed outside the housing through the second opening. In this technical solution, by providing a second opening on the side wall of the housing to expose the knob, the user can directly apply force to the knob through the second opening, making it easier and more convenient to use.

[0013] As an improvement, the size of the first roller is larger than that of the second roller; the first roller is provided with a first annular groove for accommodating part of the transmission belt, and the second roller is provided with a second annular groove for accommodating part of the transmission belt. In this technical solution, the first roller and the second roller are provided with different sizes, and the smaller second roller is installed closer to the first outlet, making the spatial distribution more reasonable and the structure more compact. The larger first roller drives the smaller second roller, making the transmission more reliable and efficient. By providing a first annular groove on the first roller and a second annular groove on the second roller, the first annular groove and the second annular groove cooperate to install the limited transmission belt, making the installation of the transmission belt simpler and more reliable, and improving the transmission efficiency.

[0014] As an improvement, the housing includes side panels and a cover panel. The cover panel is rotatably mounted above the side panels and can be rotated open and closed relative to the side panels to replace the tape. In this technical solution, the housing is composed of side panels and a cover panel. One end of the cover panel is rotatably connected to the side panels, and the other end of the cover panel is elastically connected to the side panels. The cover panel is subjected to force and can be rotated open and closed relative to the side panels, thereby opening the housing to facilitate user replacement of the tape, extending the overall service life and improving usage efficiency.

[0024] like Figures 1 to 5 As shown, the present application discloses a tape holder, comprising a housing 1, a mounting portion for storing the tape 7 being provided in the housing 1, a first opening 11 for outputting the tape 7 being provided in the housing 1, a cutter 2 being installed at the first opening 11, an output mechanism 3 for conveying the tape 7 being installed between the mounting portion and the first opening 11, the tape 7 being mounted in the mounting portion, and the tape 7 being pulled out from the first opening 11 during use, and being cut by the cutter 2, thereby eliminating the need for additional tools such as scissors or a knife, and improving ease of use, and by installing the output mechanism 3 for conveying the tape 7 between the mounting portion and the first opening 11, the output mechanism 3 conveys the tape 7 of the mounting portion to the first opening 11 by rotation, thereby improving the efficiency of pushing out the tape 7, and making it easier for the user to take out the tape 7 with less effort;

[0025] A switch 4 is movably mounted on the housing 1, and the switch 4 is connected to a reset elastic member. A one-way transmission mechanism 5 is installed between the switch 4 and the output mechanism 3. The switch 4 is subjected to force and drives the output mechanism 3 to rotate in one direction through the one-way transmission mechanism 5. The output mechanism 3 rotates to transport the tape 7 from the mounting portion to the first opening 11. In this solution, the switch 4 is mounted on the housing 1, and the switch 4 and the output mechanism 3 are linked by the one-way transmission mechanism 5. The one-way transmission mechanism 5 can only drive the output mechanism 3 to rotate along the output direction of the tape 7. When the user applies force to the switch 4, the switch 4 is subjected to force on the one-way transmission mechanism 5, and the one-way transmission mechanism 5 drives the output mechanism 3 along the output direction of the tape 7. 3 rotates, so that the adhesive tape 7 can be transported from the mounting portion to the first opening 11, and the force applied to the switch 4 is proportional to the output length of the adhesive tape 7. Each time the user applies force to the switch 4 to the maximum, the output length of the adhesive tape 7 is the same, which is more convenient and labor-saving to use. When the user removes the force on the switch 4, the switch 4 automatically resets under the action of the elastic reset member. At this time, under the action of the one-way transmission mechanism 5, the switch 4 cannot drive the output mechanism 3 to rotate in the opposite direction, which can prevent the output adhesive tape 7 from being retracted. Each time the user applies force to the switch 4, a new section of adhesive tape 7 can be output, which is more labor-saving and reliable in actual use, simplifies the structural design, and improves the transmission efficiency.

[0026] More specifically, the one-way transmission mechanism 5 includes a transmission gear 51 and a one-way drive disk 52. The transmission gear 51 is engaged with the switch 4, and the one-way drive disk 52 is connected to the output mechanism 3. The one-way transmission mechanism 5 is arranged to be engaged and linked with the switch 4 through the transmission gear 51. The one-way transmission mechanism 5 is arranged to be linked with the output mechanism 3 through the one-way drive disk 52. The switch 4 is subjected to force to drive the transmission gear 51 to rotate. The transmission gear 51 can drive the one-way drive disk 52 to rotate synchronously. The one-way drive disk 52 drives the output mechanism 3 to rotate along the output direction of the tape 7 by rotating, thereby realizing the output of the tape 7. The transmission structure is simple and efficient.

[0027] More specifically, the output mechanism 3 includes a first roller 31, a second roller 32 and a transmission belt 33. The first roller 31 and the second roller 32 are connected by the transmission belt 33. The one-way drive disk 52 is connected to the first roller 31. The output mechanism 3 includes the first roller 31 and the second roller 32. The double-roller structure design can extend the conveying path of the tape 7, making the conveying of the tape 7 more stable and reliable, and the first roller 31 and the second roller 32 are connected by the transmission belt 33. The transmission belt 33 enables the first roller 31 and the second roller 32 to rotate synchronously, thereby improving the conveying efficiency. The transmission belt 33 includes but is not limited to a belt and a rubber band, has a simple structure and is conducive to improving the transmission efficiency. A one-way drive disk 52 is provided to be connected to the first roller 31, and the one-way drive disk 52 is subjected to force to drive the first roller 31 to rotate along the output direction of the tape 7. The transmission connection is simple and reliable.

[0028] More specifically, the first roller 31 is provided with a mounting groove 311 for accommodating the one-way drive disc 52, and the one-way drive disc 52 is provided with a plurality of ratchet teeth 521. An inner gear ring 312 adapted to the ratchet teeth 521 is provided in the mounting groove 311. The ratchet teeth 521 and the inner gear ring 312 are elastically matched. The mounting groove 311 is provided in the first roller 31 for installing the one-way drive disc 52. The one-way drive disc 52 is elastically matched with the inner gear ring 312 in the mounting groove 311 through the ratchet teeth 521. When the one-way drive disc 52 is in a state of rotation, the one-way drive disc 52 is rotated. When the movable disk 52 is forced to rotate in the output direction of the tape 7, the ratchet 521 abuts against the inner gear ring 312 to drive the first roller 31 to rotate in the output direction of the tape 7, thereby outputting the tape 7. When the one-way driving disk 52 is forced to rotate in the opposite direction of the output direction of the tape 7, the ratchet 521 avoids the inner gear ring 312 under the action of elastic force, and the first roller 31 is not subjected to the driving force. Therefore, the output mechanism 3 is stationary, which can prevent the tape 7 from being retracted. The structural design is ingenious and the transmission coordination is efficient.

[0029] More specifically, the switch 4 is provided with a rotating shaft 41, which is rotatably connected to the shell 1 through the rotating shaft 41. The switch 4 is located at the upper part of the shell 1, and the switch 4 is arranged to rotate with the shell 1. The switch 4 is a push-type switch 4, and the switch 4 rotates under the action of pressing force. The switch 4 acts on the transmission gear 51 through rotation, and the transmission gear 51 is driven by the force to drive the one-way driving member to rotate synchronously, thereby driving the output mechanism 3 to rotate to output the tape 7, which is labor-saving and convenient to use; in this application, the reset elastic member is preferably a torsion spring, which has a simple and reliable structure and a small size; on the other hand, in this solution, the switch 4 is set at the upper part of the shell 1, and the user can directly press the switch 4 when holding the shell 1 for use, so as to realize one-handed operation, which is more labor-saving and convenient to use, and has a better user experience. Moreover, the push-type switch 4 is set at the upper part of the shell 1, and the user is not likely to touch it by mistake, thereby avoiding waste of the tape 7.

[0030] More specifically, the switch 4 is provided with an arc-shaped rack 42 adapted to the transmission gear 51. The switch 4 is engaged with the transmission gear 51 through the arc-shaped rack 42. By providing the arc-shaped rack 42 on the switch 4, the switch 4 is engaged with the transmission gear 51 through the arc-shaped rack 42. When the switch 4 is rotated under force, the arc-shaped rack 42 can drive the tooth transmission gear 51 to rotate, and the transmission cooperation is reliable and efficient.

[0031] More specifically, the mounting portion is rotatably installed with a knob 6, which is used to cover the tape 7 and drive the tape 7 to rotate. The knob 6 is rotated under force to recycle the tape 7, and the tape 7 is stored in the mounting portion. By installing the knob 6 on the mounting portion, the mounting portion covers the tape 7 through the knob 6. The knob 6 can be rotated on the mounting portion and drive the tape 7 to rotate synchronously. When the tape 7 is output too much, the user can apply force on the knob 6 to rotate the knob 6 in the direction opposite to the output direction of the tape 7. The knob 6 drives the tape 7 to rotate and recycle the tape 7, thereby avoiding waste of the tape 7 and meeting more usage needs.

[0032] More specifically, a second opening 12 adapted for the knob 6 is provided on the shell 1, and the knob 6 is exposed to the outside of the shell 1 through the second opening 12. By providing a second opening 12 on the side wall of the shell 1 to expose the knob 6, the user can directly apply force to the knob 6 through the second opening 12, which is simpler and more convenient to use.

[0033] More specifically, the size of the first roller 31 is larger than that of the second roller 32. The sizes of the first roller 31 and the second roller 32 are different, and the smaller second roller 32 is installed closer to the first outlet, so that the spatial distribution is more reasonable and the structure is more compact. The larger first roller 31 drives the smaller second roller 32, and the transmission is more reliable and efficient.

[0034] More specifically, the first roller 31 is provided with a first annular groove 313 for accommodating part of the transmission belt 33, and the second roller 32 is provided with a second annular groove 321 for accommodating part of the transmission belt 33. By providing the first annular groove 313 on the first roller 31 and the second annular groove 321 on the second roller 32, the first annular groove 313 and the second annular groove 321 cooperate to install the limiting transmission belt 33, so that the installation of the transmission belt 33 is simpler and more reliable, thereby improving the transmission efficiency.

[0035] More specifically, the shell 1 includes a side panel 13 and a cover panel 14. The cover panel 14 is rotatably installed above the side panel 13. The cover panel 14 can be rotated to open and close relative to the side panel 13 to replace the tape 7. The shell 1 is composed of a side panel 13 and a cover panel 14. One end of the cover panel 14 is rotatably connected to the side panel 13, and the other end of the cover panel 14 is elastically snap-connected to the side panel 13. The cover panel 14 can be rotated to open and close relative to the side panel 13 under force, so that the shell 1 is opened to facilitate the user to replace the tape 7, thereby extending the overall service life and improving the use efficiency.

[0036] This application is not limited to the above-mentioned optimal implementation method. Anyone can derive various other forms of products based on the inspiration of this application.
