Description

Technical Field

[0001] This application relates to the technical field of toilet paper rolls, and in particular to a mechanically automatic fixed-length paper-cutting wall-mounted toilet paper roll. Background Technology

[0002] Toilet paper is a paper product used for hygiene and cleaning. It has multiple rows of perforations at equal intervals to divide it into sections, making it easy for users to take each section. Toilet paper is usually stored in a toilet paper holder for easy access and protection.

[0003] In related technologies, toilet paper rolls generally include a box body and a rotating shaft. The rotating shaft passes through the core of the toilet paper roll and is rotatably connected to the box body. The box body has a paper outlet, from which the user can pull out the toilet paper roll.

[0004] Facial tissues are convenient to use, as they can be pulled out with one hand and only the amount needed. However, rolls of toilet paper generally require both hands to cut, making them less convenient. Furthermore, when cutting the roll, the tissue often extends beyond the box, making it prone to getting dirty and affecting the user experience. Summary of the Invention

[0005] To facilitate one-handed cutting of the paper roll and reduce the length of the cut paper roll extending beyond the box body, this application provides a wall-mounted paper roll box with mechanical automatic fixed-length cutting.

[0006] This application provides a mechanical automatic fixed-length paper cutting wall-mounted roll paper box, which adopts the following technical solution: A wall-mounted roll paper box with automatic fixed-length paper cutting mechanism includes a box body, a support component, a rotating shaft assembly, and a paper cutting lever. The support component is connected to the inside of the box body, and the rotating shaft assembly is connected to the support component. The rotating shaft assembly is used to pass through the roll paper. The paper-breaking paddle is disposed on the bearing assembly. The paper-breaking paddle abuts against the paper output section of the roll, and the side wall of the paper-breaking paddle abuts against the paper output section of the roll, causing the roll to break from the easily broken tooth hole.

[0007] By adopting the above technical solution, the paper-cutting lever presses against the paper output section of the roll, keeping the paper output section taut. When the user pulls out the roll, the paper output section comes into contact with the side wall of the paper-cutting lever, causing the roll to break at the easy-tear perforation. The user then continues to pull the roll, completely cutting it at the easy-tear perforation, facilitating one-handed cutting. Furthermore, the paper-cutting lever is located inside the box, reducing the length of the cut paper output section extending beyond the box.

[0008] Optionally, two paper-cutting paddles are provided at intervals, and the two paper-cutting paddles are respectively pressed against both sides in the width direction of the roll paper.

[0009] By adopting the above technical solution, the two paper-cutting paddles can simultaneously press against the paper output section from both sides of the paper roll width direction, improving the stability and accuracy of paper cutting. This allows the easy-tear teeth of the paper roll to break first from both sides, making it easier for the user to continue applying force to completely cut the paper roll. This reduces the possibility of the paper roll shifting or tearing unevenly during the paper cutting process, thus improving the user experience.

[0010] Optionally, the load-bearing component includes a support frame, which is connected to the housing, and a sliding component is slidably disposed on the support frame; The rotating shaft assembly includes a rotating shaft rod and a retaining ring. The rotating shaft rod is rotatably disposed relative to the sliding assembly and passes through the core of the paper roll. The retaining ring is connected to the rotating shaft rod and engages with the core of the paper roll.

[0011] By adopting the above technical solution, the rotating shaft passes through the core of the paper roll, and the retaining ring engages with the core of the paper roll. Pulling the paper roll allows it to rotate inside the box. As the paper roll is used, its diameter gradually decreases, while the sliding component slides on the support frame, causing the paper roll to gradually move downwards. The paper roll is always in contact with the paper-cutting lever, which helps the paper-cutting lever to cut the paper roll.

[0012] Optionally, two rotating shafts are provided, and each end of the two rotating shafts is provided with a locking tooth. The ends of the two rotating shafts are coaxially locked together by the locking teeth. Multiple retaining rings are provided, and the multiple retaining rings are respectively connected to the ends of the rotating shafts away from the locking teeth.

[0013] By adopting the above technical solution, the two rotating shafts are inserted into the core of the paper roll from both ends of the paper roll axis, so that the retaining ring is engaged with the core of the paper roll. The ends of the two rotating shafts are coaxially engaged by the engaging teeth, which is conducive to the splicing of the two rotating shafts, thus making it easier to install the paper roll on the rotating shafts.

[0014] Optionally, the retaining ring includes a supporting ring body and a retaining spring piece, and multiple supporting ring bodies are connected to the rotating shaft; multiple retaining spring pieces are provided, and the retaining spring pieces are connected to the supporting ring body and engage with the core of the paper roll.

[0015] By adopting the above technical solution, during the process of inserting the rotating rod into the core of the paper roll, the core of the paper roll causes the retaining spring to deform, so that the retaining spring engages with the core of the paper roll, thereby realizing the engagement between the core of the paper roll and the retaining ring.

[0016] Optionally, the sliding assembly includes a sliding seat and a sliding fastener, the support frame is provided with a sliding groove and a guide groove, the sliding seat is slidably disposed in the sliding groove; the sliding fastener is connected to the sliding seat, and the sliding fastener is slidably connected to the guide groove.

[0017] By adopting the above technical solution, the diameter of the paper roll gradually decreases as it is used, allowing the sliding seat to slide within the slide groove and the sliding fastener to slide on the guide groove, thus providing guidance for the movement of the paper roll within the box.

[0018] Optionally, the sliding seat is provided with a rotation resistance component, which includes a rotation tooth and a resistance rod; the rotation tooth is connected to the end of the rotating shaft, the resistance rod is connected to the sliding seat, the rotation tooth engages with the resistance rod, and the resistance rod provides resistance to the rotation of the rotation tooth.

[0019] By adopting the above technical solution, pulling the paper roll causes the rotating shaft to rotate, which in turn causes the rotating teeth to rotate. Since the resistance rod provides resistance to the rotation of the rotating teeth, a certain force is applied to the paper output section of the paper roll, which helps the paper-cutting lever to cut the paper roll.

[0020] Optionally, a guide assembly is also included, comprising a guide spring, a guide plate, a ratchet, and a latch; one end of the guide plate is rotatably connected to the support frame, and the other end of the guide plate is connected to the latch, which engages with the support frame; the ratchet is connected to the guide plate, and the guide spring is connected to the sliding seat, with the guide spring engaging with the ratchet; the ratchet allows the sliding seat to move unidirectionally toward the bottom of the support frame, so that the paper roll remains pressed against the paper break lever.

[0021] By adopting the above technical solution, the ratchet allows the sliding seat to move unidirectionally towards the bottom of the support frame, so that the paper roll can only move towards the bottom of the support frame. When the user pulls the paper roll quickly, it can prevent the paper roll from jumping up and down, and it can also keep the paper roll pressed against the paper cutter, which is conducive to the paper cutter cutting the paper roll.

[0022] Optionally, a paper output guide is connected to the support frame, the paper output guide is connected to the support frame, and the paper cutter is connected to the paper output guide; the paper output guide is provided with a guide outlet, through which the paper output section of the roll passes.

[0023] By adopting the above technical solution, the paper output guide frame provides support for the paper breakage lever, and pulls the paper output section of the roll paper from the guide outlet. The paper output guide frame provides guidance for the paper output section of the roll paper.

[0024] Optionally, a support roller is rotatably connected to the paper output guide frame, and the support roller is used to abut against the bottom side of the paper roll.

[0025] By adopting the above technical solution, the paper feed section of the roll is pulled to make the roll rotate, which drives the support roller to rotate, and the support roller provides support for the roll.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. The paper-cutting lever design allows the roll of paper to break from the easy-tear perforation, making it easy to cut the roll of paper with one hand. It also reduces the length of the paper-exit section, reducing the problem of contamination of the protruding roll of paper and improving ease of use and hygiene. 2. The two paper-cutting paddles can simultaneously press against the paper output section from both sides of the paper roll width, causing the paper roll to break from both sides first at the easy-tear teeth. This allows the user to continue applying force to completely cut the paper roll, reducing the possibility of the paper roll shifting or tearing unevenly during the cutting process and improving the user experience. 3. Pull the paper roll, and the paper roll will drive the rotating shaft to rotate. The rotating shaft will drive the rotating cleaver to rotate. Because the resistance rod provides resistance to the rotation of the rotating cleaver, a certain force is applied to the paper output section of the paper roll, which is conducive to the paper cutting lever cutting the paper roll.

[0032] refer to Figure 3 and Figure 4 The supporting component 2 includes a support frame 21, a paper output guide frame 22 and a support roller 23. Two support frames 21 are spaced apart. The support frames 21 are fixedly connected to the support shell 11 and are inclined.

[0033] refer to Figure 4 and Figure 5 Two sliding components 4 are provided, each corresponding to one of the two support frames 21. Each sliding component 4 includes a sliding seat 41 and a sliding fastener 42, which are fixedly connected. The support frame 21 has a sliding groove 211, within which the sliding seat 41 is slidably connected. The support frame 21 also has a guide groove 212, with the sliding fastener 42 slidably connected to the guide groove 212. The sliding fastener 42 engages with the support frame 21, confining the sliding seat 41 within the sliding groove 211.

[0034] refer to Figure 2 and Figure 3The rotating shaft assembly 3 includes a rotating shaft rod 31, a retaining ring 32, and reinforcing ribs 33. The rotating shaft rod 31 is rotatably connected to the sliding seat 41 and can rotate relative to the sliding seat 41. Two rotating shaft rods 31 are provided, each with a retaining tooth 311 at its end, and the ends of the two rotating shaft rods 31 are coaxially engaged by the retaining teeth 311. Two retaining rings 32 are provided, each corresponding to one of the two rotating shaft rods 31. Each retaining ring 32 includes a supporting ring body 321 and a retaining spring piece 322. The supporting ring body 321 is fixedly connected to the end of the rotating shaft rod 31 away from the retaining tooth 311. Multiple reinforcing ribs 33 are fixedly connected to both the supporting ring body 321 and the rotating shaft rod 31, and multiple reinforcing ribs 33 are arranged around the axis of the rotating shaft rod 31. The retaining spring 322 is fixedly connected to the support ring 321, and multiple retaining springs 322 are arranged around the axis of the support ring 321. In the direction from one end of the rotating shaft 31 with the retaining teeth 311 to the other end, the retaining spring 322 and the support ring 321 are flared, which can accommodate cores of different diameters of paper rolls.

[0035] refer to Figure 2 and Figure 3 In use, first separate the two rotating shaft rods 31, then insert the two rotating shaft rods 31 into the two ends of the paper roll core. As they are gradually inserted, the ends of the two rotating shaft rods 31 are coaxially engaged by the snap-fit ​​teeth 311, and the snap-fit ​​spring piece 322 is engaged with the paper roll core, thereby fixing the paper roll and the rotating shaft assembly 3 relative to each other and realizing the installation of the paper roll and the rotating shaft assembly 3.

[0036] refer to Figure 2 and Figure 3 The paper output guide frame 22 is fixedly connected to the support frame 21, and the paper output guide frame 22 is snapped into the support shell 11. The paper output guide frame 22 is provided with a guide outlet 221, which corresponds to the paper output port 121. The support roller 23 is rotatably connected to the paper output guide frame 22, and the support roller 23 is located on the inner bottom side of the box body 1. The paper output guide frame 22 is fixedly connected with a paper breaker 7. After the roll of paper is installed on the rotating shaft assembly 3, the bottom side of the roll of paper abuts against the support roller 23. Under the action of gravity of the roll of paper, the paper output section abuts against the paper breaker 7, and the paper output section of the roll of paper can extend out of the outside of the box body 1 from the guide outlet 221 and the paper output port 121. Two paper breakers 7 are provided at intervals, and the two paper breakers 7 are located on both sides in the width direction of the roll of paper.

[0037] refer to Figure 2 and Figure 3When the paper roll is pulled, it drives the support roller 23 to rotate. The easily broken teeth of the paper output section pass through the paper-breaking deflector 7, and the two sides of the paper output section are subjected to force. The paper-breaking deflector 7 causes the easily broken teeth on both sides of the paper output section to break first, making the paper output section easier to cut. As the user continues to pull the paper roll, the easily broken teeth in the middle of the paper output section break due to the paper roll pressing against the paper-breaking deflector 7, thus completely cutting off the paper output section.

[0038] refer to Figure 5 and Figure 6 A rotational resistance component 5 is provided between the rotating shaft assembly 3 and the sliding assembly 4. The rotational resistance component 5 includes rotating teeth 51 and a resistance rod 52. The rotating teeth 51 are fixedly connected to the end of the rotating shaft 31, and multiple rotating teeth 51 are arranged in a circumferential array around the axis of the rotating shaft 31. The resistance rod 52 is fixedly connected to the sliding seat 41, and the rotating teeth 51 engage with the resistance rod 52. The resistance rod 52 provides a certain resistance when the rotating teeth 51 rotates, so that a certain force is required to pull the paper roll, which is beneficial for the paper-breaking pry bar 7 to tear the easily broken teeth in the paper output section of the paper roll.

[0039] refer to Figure 3 and Figure 5 The support frame 21 is equipped with a guide assembly 6, which includes a guide spring 61, a guide plate 62, a ratchet 63, and a latch 64. The bottom end of the guide plate 62 is rotatably connected to the bottom end of the support frame 21, and the top end of the guide plate 62 is fixedly connected to the latch 64, which engages with the top end of the support frame 21. The ratchet 63 is integrally formed with the guide plate 62, and the guide spring 61 is fixedly connected to the sliding seat 41 by screws, with the guide spring 61 tilted upward. The guide spring 61 abuts against the ratchet 63, which allows the guide spring 61 to move downward, i.e., the ratchet 63 allows the sliding seat 41 to move unidirectionally towards the bottom end of the support frame 21, so that the paper roll can only move downward. When the user quickly pulls the paper roll, it can prevent the paper roll from jumping up and down, and it can also keep the paper roll pressed against the paper-cutting lever 7, which is beneficial for the paper-cutting lever 7 to cut the paper roll.

[0040] The implementation principle of a wall-mounted paper roll box with automatic fixed-length paper cutting according to an embodiment of this application is as follows: When the paper roll is pulled out, the easily broken teeth of the paper roll pass through the paper-cutting lever 7. The paper-cutting lever 7 causes the easily broken teeth on both sides of the paper roll to break first. As the user continues to pull out the paper roll, the easily broken teeth in the middle of the paper roll break, thereby cutting off a section of the paper roll. The rotation resistance component 5 provides resistance to the rotation of the paper roll, which is beneficial for the paper-cutting lever 7 to cut the paper roll.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
