Description

Technical Field

[0001] This utility model relates to the technical field of tape cutters, and more specifically to a press-operated automatic tape feeder. Background Technology

[0002] Tape cutters are widely used in carton sealing, cargo packaging reinforcement, and everyday item sealing and paper pasting. Existing tape cutters, for safety, cleanliness, and aesthetics, are often designed like correction tape, with the tape enclosed within a housing. To use them, the end of the tape must first extend out of the housing for easy application to the item. Then, the housing is pulled in the direction of application, extending the tape and applying it to the item. The tape is then cut using a blade mounted on the housing, ensuring the cut end remains inside the housing to prevent dust or other contaminants from adhering. This process, requiring the tape end to extend out of the housing before use and to remain inside after use, is present in various existing technologies. This application proposes a novel tape cutter structure that differs from existing technologies, offering greater ease of use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a press-operated automatic tape cutter that allows the tape to extend a certain length outside the housing with one hand, making it easy to stick to items; similarly, it can cut the tape with one hand, and the cut end of the tape is located inside the housing to prevent it from sticking to external items.

[0004] The technical solution of this utility model is to provide a press-operated automatic belt conveyor cutter, including a housing, a tape, a blade, and an automatic belt conveyor assembly disposed within the housing and between the tape and the blade. The automatic belt conveyor assembly includes a button, a synchronous belt drive assembly, and a one-way drive component. The synchronous belt drive assembly includes a drive wheel, a driven wheel, and a conveyor belt tensioned between the drive wheel and the driven wheel. The button is linked to the one-way drive component, which drives the drive wheel in one direction. The conveyor belt is used to bond the tape. Pressing the button causes the one-way drive component to drive the drive wheel to rotate in one direction and rotate the conveyor belt. The rotation of the conveyor belt drives the tape forward toward the blade. The blade is used to cut the tape. An elastic reset component is provided between the button and the housing. The elastic reset component undergoes elastic deformation when the button is pressed and resets the button upon rebound.

[0005] Compared with existing technologies, the automatic conveyor belt cutter of this invention has the following advantages: It can be held with one hand, and pressing the button with a finger allows the end of the tape to extend out of the housing for easy application to items; because the unidirectional transmission component drives the drive wheel in one direction, the drive wheel will not reverse its movement when the button is reset, meaning the conveyor belt will not retract the tape end into the housing; the tape used for applying items is positioned opposite the blade, and after the tape is applied to the item, the blade can be pressed onto the tape with one hand, and a slight force can cut the tape, keeping the cut end inside the housing to prevent it from sticking to external items; in summary, the automatic conveyor belt cutter of this invention has a simple structure and is easy to use.

[0006] Preferably, a transmission gear is provided between the button and the one-way transmission component, and a rack is provided on the button. The rack meshes with the transmission gear, and the transmission gear coaxially drives the one-way transmission component. With this structure, pressing the button and depressing the rack drives the transmission gear to rotate, resulting in a simple structure.

[0007] Preferably, a double gear is provided between the button and the transmission gear. The rack meshes with the small gear of the double gear, and the large gear of the double gear meshes with the transmission gear. The diameter of the large gear of the double gear is larger than the diameter of the transmission gear. With this structure, the rack meshes with the small gear of the double gear, and the small gear and the large gear rotate at the same angle, but the large gear produces a larger displacement, i.e., a displacement amplification effect. Similarly, the large gear meshes with the transmission gear, and since the diameter of the large gear is larger than that of the transmission gear, for the same displacement, the transmission gear rotates at a larger angle, i.e., an angle amplification effect. Thus, a small press of the button can produce two levels of amplification, resulting in a large-angle rotation of the transmission gear. This transmission to the synchronous belt drive assembly enables the conveyor belt to move the adhesive tape a larger distance.

[0008] Preferably, a drive shaft is provided at the center of the transmission gear, and a limiting sleeve is provided on the one-way transmission component. The limiting sleeve is fitted onto the transmission shaft, and the limiting sleeve is circumferentially limitingly engaged with the transmission shaft. This structure is simple and facilitates the transmission gear to drive the one-way transmission component.

[0009] Preferably, the unidirectional transmission component is a ratchet, with at least one pawl on the circumferential surface of the limiting sleeve; an internal gear ring is provided on the driving wheel; the driving wheel is sleeved on the limiting sleeve, and the pawl and internal gear ring constitute a ratchet mechanism, which provides unidirectional transmission to the driving wheel. With this structure, pressing the button causes the ratchet to drive the driving wheel to rotate, while resetting the button prevents the ratchet from driving the driving wheel, ensuring that the driving wheel can only be driven in one direction.

[0010] Preferably, the housing contains at least one pressure shaft, which is opposite to the drive wheel and in contact with the conveyor belt. The pressure shaft is used to cooperate with the drive wheel to limit the adhesive tape adhered to the conveyor belt. With this structure, the cooperation between the pressure shaft and the drive wheel ensures that the adhesive tape is reliably adhered to the conveyor belt and moves smoothly with the conveyor belt, avoiding the adhesive tape from being loosely adhered and causing it to curl up or deviate during movement.

[0011] Preferably, the pressure belt shaft is rotatably connected to the housing, and the operation of the conveyor belt drives the pressure belt shaft to rotate. This structure reduces the friction between the pressure belt shaft and the conveyor belt, and reduces the resistance force of the pressure belt shaft on the forward movement of the conveyor belt.

[0012] Preferably, the housing contains at least one pressure plate, which faces the driven wheel and contacts the conveyor belt. The pressure plate cooperates with the driven wheel to limit the tape adhered to the conveyor belt. With this structure, the cooperation between the pressure plate and the driven wheel ensures that the tape reliably and smoothly moves with the conveyor belt, preventing the tape from warping or shifting due to weak adhesion. When the tape is cut with a blade, the cooperation between the pressure plate and the driven wheel ensures that the tape is reliably adhered to the conveyor belt, preventing the ends of the tape from detaching from the conveyor belt.

[0013] Preferably, the housing includes a base and a movable outer shell. The movable outer shell has a pivot connection hole on the same side as the blade and a latch on the same side as the tape. The base has a first pivot and a buckle. The pivot connection hole is fitted onto the first pivot, and the latch and buckle are engaged. With this structure, to replace the tape, the latch and buckle are disengaged, allowing the movable outer shell to flip upwards around the first pivot, facilitating tape replacement. After tape replacement, the movable outer shell is flipped downwards to re-engage the latch and buckle, making operation convenient.

[0014] Preferably, the movable outer shell is provided with an opening rib, which is adjacent to the latch and used to pry the movable outer shell into contact with the snap-fit ​​connection of the base. With this structure, the opening rib can also act as a handle to pry open the latch and buckle connection, making operation convenient. Attached Figure Description

[0021] To better understand this application, various aspects of this application will be described in more detail with reference to the accompanying drawings. It should be understood that these detailed descriptions are merely illustrative of exemplary embodiments of this application and are not intended to limit the scope of this application in any way. Throughout the specification, the same reference numerals refer to the same elements.

[0023] It should also be understood that the terms "comprising," "having," "including," and "containing," when used in this specification, indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof. Furthermore, when expressions such as "...at least one" appear after a list of listed features, they modify the entire listed feature, not individual elements in the list.

[0024] like Figure 1 and 2As shown, the automatic belt conveyor cutter of this utility model includes a housing, a tape 14, a blade 12 disposed within the housing, and an automatic belt conveyor assembly disposed between the tape 14 and the blade 12. The automatic belt conveyor assembly includes a button 4, a synchronous belt drive assembly, and a one-way drive component. The synchronous belt drive assembly includes a drive wheel 8, a driven wheel 9, and a conveyor belt 10 tensioned between the drive wheel 8 and the driven wheel 9. The button 4 is linked to the one-way drive component, which drives the drive wheel 8 in one direction. The conveyor belt 10 is used to bond the tape 14. Pressing the button 4 causes the one-way drive component to drive the drive wheel 8 to rotate in one direction and cause the conveyor belt 10 to rotate. The rotation of the conveyor belt 10 drives the tape 14 to move forward in one direction towards the blade 12, thus bringing the end of the tape 14 out of the housing and achieving tape output.

[0025] The housing includes a base 2 and a movable outer shell 1, such as Figure 5 As shown, a detachable side cover 3 is provided on one side of the base 2. The base 2 and the side cover 3 cooperate and are provided with a first rotating shaft 2-1, a second rotating shaft 2-2, a third rotating shaft connecting part 2-3, a fourth rotating shaft 2-4, and a buckle 2-5. Figure 4 As shown, the movable outer shell 1 is provided with a blade mounting position 1-3, a rotating shaft connecting hole 1-5, a pressure plate 1-4, a spring seat 1-1, a bayonet 1-6, and a cover-opening rib 1-7. The blade 12 is set in the blade mounting position 1-3, and the tape 14 is rotatably connected to the fourth rotating shaft 2-4. The rotating shaft connecting hole 1-5 is on the same side as the blade 12, and the bayonet 1-6 is on the same side as the tape 14. The rotating shaft connecting hole 1-5 is fitted onto the first rotating shaft 2-1, the bayonet 1-6 is snapped into place with the buckle 2-5, and the cover-opening rib 1-7 is adjacent to the bayonet 1-6, used to pry the movable outer shell 1 into contact with the base 2 for snap-fit ​​connection.

[0026] like Figure 2 and Figure 3 As shown, a spring 13 is installed inside the spring seat 1-1, and the button 4 is connected to the spring 13. The spring 13 acts as an elastic reset element between the button 4 and the movable housing 1. When the button 4 is pressed, it undergoes elastic deformation and resets the button 4 upon rebound. A rack 4-1 is provided on the button 4, and a rack hole 1-2 is provided on the spring seat 1-1. The rack 4-1 passes through the rack hole 1-2 and enters the housing.

[0027] The third rotating shaft connecting part 2-3 is provided with a double gear 5, and the rack 4-1 meshes with the small gear of the double gear 5 for transmission; the second rotating shaft 2-2 is provided with a transmission gear 6, and the large gear of the double gear 5 meshes with the transmission gear 6 for transmission. The diameter of the large gear of the double gear 5 is larger than the diameter of the transmission gear 6.

[0028] A drive shaft 6-1 is provided at the center of the drive gear 6, and the drive shaft 6-1 is sleeved on the second rotating shaft 2-2; a ratchet 7 is provided on the drive shaft 6-1, and a limit sleeve 7-1 is provided on the ratchet 7. The limit sleeve 7-1 is sleeved on the drive shaft 6-1, and the limit sleeve 7-1 is circumferentially limited and engaged with the drive shaft 6-1. The drive gear 6 drives the ratchet 7 coaxially; two pawls are symmetrically arranged on the circumferential surface of the limit sleeve 7-1 on the ratchet 7.

[0029] The driven wheel 9 of the synchronous belt drive assembly is sleeved on the first rotating shaft 2-1, and the driving wheel 8 is sleeved on the limiting bushing 7-1. The driving wheel 8 is provided with an internal gear ring 8-1. The pawl and the internal gear ring 8-1 constitute a ratchet mechanism. The ratchet mechanism provides one-way transmission to the driving wheel 8, that is, the one-way transmission component is the ratchet 7.

[0030] The movable housing 1 contains two rotatable pressure shafts 11. These shafts are opposite to the drive wheel 8 and contact the conveyor belt 10. The rotation of the conveyor belt 10 drives the pressure shafts 11 to rotate. The pressure shafts 11 cooperate with the drive wheel 8 to limit the adhesive tape 14 adhered to the conveyor belt 10. The movable housing 1 also contains a pressure plate 1-4. This plate is opposite to the driven wheel 9 and contacts the conveyor belt 10. The pressure plate 1-4 cooperates with the driven wheel 9 to limit the adhesive tape 14 adhered to the conveyor belt 10.

[0031] This utility model discloses an automatic conveyor belt cutter that can be operated with one hand. Pressing button 4 depresses rack 4-1, driving the small gear of the double gear 5 to rotate. The large gear of the double gear 5 rotates synchronously, and for the same rotation angle, the large gear produces a larger displacement. That is, rack 4-1 driving the small gear amplifies the displacement of the large gear. The large gear, with a diameter larger than that of the transmission gear 6, rotates at a larger angle for the same displacement, thus amplifying the angle. The transmission gear 6 then rotates coaxially with ratchet 7, which in turn drives the drive wheel 8 in one direction. In this way, a small press of button 4 produces two-stage amplification, causing the conveyor belt 10 to move a larger distance along the direction of the adhesive tape 14 towards the blade 12, allowing the tape end to smoothly extend out of the housing and exit. Releasing button 4 resets the button 4, preventing the drive wheel 8 from reversing its movement, thus preventing the conveyor belt 10 from retracting the tape end back into the housing.

[0032] As the conveyor belt 10 moves carrying the adhesive tape 14, the pressure shaft 11, in cooperation with the drive wheel 8, ensures that the tape is reliably adhered to the conveyor belt 10 and moves smoothly with it, preventing the tape from warping or shifting due to weak adhesion. When the end of the tape 14 is attached to an item and the automatic conveyor belt cutter of this invention is pulled, the tape 14 can continue to be pulled out of the housing. The synchronous belt drive assembly can rotate with the tape 14, but the drive wheel 8 cannot reverse the rotation of the ratchet 7. During this process, the pressure plates 1-4, in cooperation with the driven wheel 9, ensure that the tape reliably and smoothly moves with the conveyor belt 10 and adheres to the item.

[0033] The adhesive tape 14 for attaching items is positioned opposite the blade 12. After the tape is applied to the item, the blade 12 can be pressed onto the tape 14 with one hand, and a slight force can cut the tape 14, ensuring that the cut end of the tape 14 is inside the housing to prevent it from sticking to external items. When cutting the tape 14 with the blade 12, the pressure plate 1-4, in conjunction with the driven wheel 9, ensures that the tape is reliably adhered to the conveyor belt 10, preventing the tape end from detaching from the conveyor belt 10 and affecting the next operation.

[0034] When changing the tape, the protruding rib 1-7 of the cover can be used as a handle to pry open the buckle connection between the latch 1-6 and the buckle 2-5. After prying open the buckle connection between the latch 1-6 and the buckle 2-5, the movable outer shell 1 can be flipped up around the first pivot 2-1, which makes it easy to change the tape. After changing the tape, the movable outer shell 1 can be flipped down to re-engage the latch 1-6 and the buckle 2-5. The operation is convenient.

[0035] The above are merely specific embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Any modifications or equivalent substitutions to this utility model without departing from its spirit and scope should be covered within the protection scope of the claims of this utility model.
