Description

Technical Field

[0001] This invention relates to the field of paper roll technology, and more particularly to a mechanical automatic paper roll feeder. Background Technology

[0002] As a necessity in daily life, toilet paper rolls are consumed in large quantities. Statistics show that a three-person household uses at least one roll of toilet paper per week on average. The standard generally followed for toilet paper is GB / T20810-2018 "Toilet Paper (including toilet paper base paper)," designed for toilet use. To facilitate dissolution, it has relatively poor toughness, easily dispersing upon contact with water after use, reducing the risk of sewer blockage. Therefore, during use, waste can easily occur due to water, oil, or excessively large amounts drawn at once.

[0003] Furthermore, when using roll toilet paper, people typically need to use one hand to pull out the roll and then use the other hand to hold it steady and pull it apart. At this point, both hands are usually quite dirty, and the remaining tissue paper will retain dirt or bacteria from the hands, wasting paper and potentially infecting others who use it – a very unhygienic practice. Typically, toilet paper dispensers are installed on the side of the toilet, making it inconvenient to tear the roll with two hands, thus affecting the usability of the dispenser.

[0004] Placing toilet paper in a tissue box can achieve waterproofing, oil resistance, and dust protection, thereby reducing toilet paper waste and lowering daily consumption costs. Currently, there are many types of toilet paper boxes on the market; however, most focus excessively on aesthetic design while neglecting practicality. Users need to use both hands to cut the paper when retrieving it, which is inconvenient; the paper outlet is too small, making initial paper feeding difficult; after being torn, the toilet paper tends to retract into the box, making subsequent retrieval difficult; furthermore, if the user's hands are wet, the toilet paper is easily soaked, and more sheets are taken, resulting in significant waste. Some tissue boxes are electrically driven, using sensors to automatically dispense paper. These require a power source, regular battery replacements, or the installation of electrical outlets. Maintenance is inconvenient in humid environments with frequent use, and issues such as sensor malfunction and safety hazards may arise.

[0005] In existing technologies, such as Figure 10 Patent application number "CN201620226123.1" discloses a tissue box that allows for easy tearing of a roll of paper after being pulled out with one hand. During use, the tissue box clamps the roll of paper when pulled out from different directions. However, because the tissue is pulled from one side, the rotating plate on the other side, which is used for clamping, can tilt under pressure, making it easy for the roll of paper to loosen during the clamping process. For example... Figure 11The patent application with application number 202011350956.6 further improved the design to address the above issues, overcoming the problem of the paper roll easily coming undone. However, the principle of paper cutting is the same as the former: when taking out the paper, a section of tissue paper needs to be pulled out first, and then the direction of pulling is such that the squeezing plate is tilted to clamp the tissue paper, thereby achieving paper cutting. This process requires hand-eye coordination to control the position of the paper cut and the amount of tissue paper, which is not very convenient.

[0006] In summary, existing tissue boxes suffer from problems such as poor tissue dispensing convenience, difficulty in feeding tissues, excessive tissue dispensing, and electrical safety concerns. Therefore, it is necessary to produce a clean, quantitative, and convenient tissue box. Summary of the Invention

[0007] The purpose of this invention is to solve the technical problems of existing tissue boxes, such as poor tissue extraction convenience, difficulty in feeding tissues, excessive tissue dispensing, and electrical safety.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a mechanical automatic paper-cutting and feeding roll box, comprising: a box body; a stop roller and a pressure roller are provided inside the box body; a paper-cutting and feeding mechanism is provided on one side of the stop roller and the pressure roller inside the box body; the paper-cutting and feeding mechanism is used to control the stop roller and the pressure roller to feed and cut the paper towel according to the user's pulling force.

[0009] Furthermore, the paper feeding mechanism includes a large gear connected to a stop roller; a second double gear and a first double gear are meshed on the side of the large gear; the second double gear meshes with a small gear on the inertia wheel shaft; the first double gear meshes with the worm of the stop rotor through the worm wheel of the stop transmission shaft; the first double gear and the second double gear are both gears of different diameters coaxially and integrally set, the large gear can mesh with the small diameter gear, and when the number of teeth of the small diameter gear is different from that of the large diameter gear, speed change can be achieved.

[0010] Furthermore, a small pulley is connected to the end of the large gear away from the stop roller, and the small pulley is connected to the adjusting roller via a circular belt; the side of the adjusting roller extends out of the box body.

[0011] Furthermore, a fixing plate is provided between the stop roller and the large gear; the large gear can be coaxially connected to the stop roller via a connecting shaft, which can pass through the fixing plate; the fixing plate separates the large gear from the connecting shaft, and the large gear, the first double gear, and the second double gear can all be mounted on the fixing plate, thereby improving the stability of the large gear, the first double gear, and the second double gear.

[0012] Furthermore, an intermediate support is provided between the large gear, the first double gear, the second double gear, the inertia wheel, and the stop transmission shaft; the intermediate support is fixed to the fixed plate by riveting; the large gear and the small pulley, the first double gear and the stop transmission shaft, and the second double gear and the inertia wheel can all be connected through the intermediate support.

[0013] Furthermore, the front cover of the box is equipped with a paper outlet for feeding out rolls of paper towels.

[0014] Furthermore, the side cover and front cover of the box body near the paper feeding mechanism are both hinged to the box body; the side cover and front cover can be opened around the hinge point; the closed side cover is fixed to the box body by a second press-type spring lock; the closed front cover is fixed to the box body by a first press-type spring lock.

[0015] Furthermore, a baffle is provided on the side wall of the box body near the area above the stop roller; the baffle is parallel to the stop roller and extends to the surface of the stop roller; the baffle is located above the stop roller and can guide and limit the paper towel to prevent the paper towel from getting stuck between the stop roller and the box body.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0017] 1. This invention provides a mechanical automatic paper-cutting and feeding roll paper box. When using a small force to pull the paper, the paper-cutting and feeding mechanism rotates at a low speed, resulting in low air resistance. The perforated line of the paper towel does not break when passing through the pressure roller area, allowing for continuous paper output. During normal paper pulling, the paper-cutting and feeding mechanism rotates at a high speed, resulting in high air resistance. The perforated line automatically breaks, achieving the paper-cutting effect. Thus, the stop roller and pressure roller are controlled to convey and break the paper towel according to the user's pulling force. During use, the paper towel can be easily pulled out with one hand without considering the pulling angle, eliminating the lifting or pressing actions required by existing single-handed paper towel dispensers. At the same time, the mechanical paper-cutting and feeding mechanism does not require a power source and is not affected by humid environments.

[0018] 2. This invention provides a mechanical automatic paper-cutting and feeding roll cassette. To prevent the paper towel from breaking precisely in the pressure roller area under special circumstances, making paper retrieval difficult, an adjusting roller is incorporated. The roller can be manually adjusted to feed the paper towel a certain length for easier retrieval. The adjusting roller is connected to a small pulley via a circular belt, and the small pulley is connected to a large gear. Therefore, by adjusting the roller, a stop roller can be rotated to feed a portion of the paper towel. Attached Figure Description

[0033] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1:

[0035] Please see Figure 1 The present invention provides a mechanical automatic paper-cutting and feeding roll box, comprising: a box body 2; a stop roller 5 and a pressure roller 6 are provided inside the box body 2; a paper-cutting and feeding mechanism 9 is provided on one side of the stop roller 5 and the pressure roller 6 inside the box body 2; the paper-cutting and feeding mechanism 9 is used to control the stop roller 5 and the pressure roller 6 to feed and cut the paper towel according to the user's pulling force.

[0036] When in use, place the continuous roll of tissue paper 4 into the box 2, pull out a portion of the continuous roll of tissue paper 4 and place it between the stop roller 5 and the pressure roller 6. The connection strength at the perforation line of the tissue paper is relatively low, and it is more likely to break after being squeezed by the pressure roller 6. When using a small force to pull the paper, the paper cutting and feeding mechanism 9 rotates at a low speed, resulting in low air resistance. The perforation line of the tissue paper does not break when passing through the pressure roller 6 area, allowing for continuous paper output. During normal paper pulling, the paper cutting and feeding mechanism 9 rotates at a high speed, resulting in high air resistance. The perforation line automatically breaks, achieving the paper cutting effect. Thus, the stop roller 5 and the pressure roller 6 are controlled to feed and break the tissue paper according to the user's pulling force. When in use, the tissue paper can be easily pulled out with one hand without considering the angle of the pull, eliminating the lifting or pressing actions required when pulling out tissue paper with existing single-handed tissue boxes. At the same time, the mechanical paper cutting and feeding mechanism 9 does not require a power source and is not affected by humid environments.

[0037] In this embodiment, the paper feeding mechanism 9 includes a large gear 98, which is connected to the stop roller 5; the large gear 98 is meshed with a second double gear 96 and a first double gear 95 on its side; the second double gear 96 meshes with a small gear on the shaft of the inertia wheel 93; the first double gear 95 meshes with the worm of the stop rotor 92 through the worm wheel of the stop transmission shaft 912; all the above components are disposed inside the housing 91.

[0038] When the tissue is pulled out, it drives the stop roller 5 and the pressure roller 6 to rotate. The stop roller 5 is connected to the large gear 98, transmitting power to the large gear 98. After the power is transmitted to the large gear 98, there are two transmission routes: the large gear 98 drives the second double gear 96 to move, which in turn drives the inertia wheel 93 to rotate. The rotation of the inertia wheel 93 can store and release kinetic energy; the large gear 98 drives the first double gear 95 to move, which in turn drives the stop transmission shaft 912 to move, so that the stop rotor 92 rotates and generates air resistance. The faster the rotation speed, the greater the resistance generated. Utilizing the principle of inertia, the paper cutting and feeding mechanism 9 can absorb energy when the tissue is pulled out and release energy after the tissue is broken, automatically feeding the tissue at the rear end. The stopping resistance of the stop rotor 92 can be adaptively adjusted, providing the resistance required for paper cutting and controlling the length of paper feeding. Compared to electric tissue boxes, this one does not require electricity, can be used in humid environments, is safe and reliable, and has low maintenance and operating costs. It is suitable for use in homes, public places, and other scenarios, and can be used for both tissues and rolls. In addition, the storage space on the side can be used to store garbage bags and other daily necessities, making it widely applicable.

[0039] like Figure 4 and Figure 5 As shown, the speed-stop roller 5 is coaxially connected to the shaft of the large gear 98. The large gear 98 meshes with the smaller diameter gear of the first double gear 95. The larger diameter gear of the first double gear 95 meshes with the small gear of the speed-stop transmission shaft 912. The worm gear of the speed-stop transmission shaft 912 meshes with the worm of the speed-stop rotor 92.

[0040] The pressure roller 6 presses the paper towel firmly to ensure there is no relative slippage between the paper towel and the stop roller 5. When the paper towel is pulled, it drives the stop roller 5 to rotate. The large gear 98 rotates coaxially with the stop roller 5, which in turn drives the first double gear 95, the stop transmission shaft 912, and the stop rotor 92 to rotate in sequence. The transmission ratios of each stage are i1 = 50 / 10, i2 = 24 / 7, and i3 = 24 / 1, and the total transmission ratio is i s1 =411.4. Therefore, after speed increase, the stop rotor 92 has a very high rotational speed. The higher the speed, the greater the air resistance experienced by the stop rotor 92, thus limiting the increase of the speed of the stop rotor 92, which in turn limits the speed of the stop roller 5.

[0041] When the force applied to the tissue is small, the tension on the tissue is less than the breaking force at the perforation line, allowing for continuous paper output. When the force applied is large, the tension on the tissue exceeds the breaking force at the perforation line but is less than the breaking force of other parts of the tissue. Once the perforation line passes the pressure roller 6 area, the tissue will automatically break. Additionally, the pattern on the surface of the stop roller 5 also provides some assistance in breaking the tissue during compression.

[0042] The stop roller 5 is coaxially connected to the large gear 98, the large gear 98 meshes with the small gear of the second double gear shaft 96, and the larger diameter gear of the second double gear 96 meshes with the small gear on the shaft of the inertia wheel 93.

[0043] The pressure roller 6 presses the paper towel firmly to ensure there is no relative slippage between the paper towel and the stop roller 5. When the paper towel is pulled, it drives the stop roller 5 to rotate. The large gear 98 rotates coaxially with the stop roller 5, which in turn drives the second double gear 96 and the inertia wheel 93 to rotate in sequence. The transmission ratios of each stage are i3 = 50 / 10 and i4 = 24 / 10, respectively, and the total transmission ratio is i. s2 =12. When the tissue is pulled out, the rotation of the inertia wheel 93 serves to store energy. After the tissue breaks, the inertia wheel 93 continues to rotate, releasing kinetic energy, which drives the stop roller 5 to rotate and deliver a section of tissue for the next tissue to be taken out. At the same time, in order to prevent the tissue from being delivered too long, the stop rotor 92 in the paper cutting mechanism also rotates, thereby consuming some of the kinetic energy of the inertia wheel 93.

[0044] In this embodiment, a small pulley 910 is connected to the end of the large gear 98 away from the stop roller 5. The small pulley 910 is connected to the adjusting roller 911 via a circular belt 99. The side of the adjusting roller 911 extends out of the box body 2.

[0045] To prevent the tissue from breaking off in the pressure roller area under special circumstances, making it difficult to retrieve, an adjusting roller 911 is provided. The roller 911 can be manually adjusted to feed the tissue a certain length for easier retrieval. The adjusting roller 911 is connected to a small pulley 910 via a circular belt 99, and the small pulley 910 is connected to a large gear 98. Therefore, by turning the adjusting roller 911, the stop roller 5 is rotated, feeding a portion of the tissue.

[0046] In this embodiment, a fixing plate 97 is provided between the stop roller 5 and the large gear 98; the large gear 98 can be connected to the stop roller 5 via a connecting shaft, which can pass through the fixing plate 97; the fixing plate 97 separates the large gear 98 from the connecting shaft, and the large gear 98, the first double gear 95, and the second double gear 96 can all be mounted on the fixing plate 97, thereby improving the stability of the large gear 98, the first double gear 95, and the second double gear 96.

[0047] In this embodiment, an intermediate support 94 is provided between the large gear 98, the first double gear 95, the second double gear 96, the inertia wheel 93, and the stop transmission shaft; the intermediate support 94 is fixed to the fixing plate 97 by screws 8; the large gear 98 and the small pulley 910, the first double gear 95 and the stop transmission shaft, and the second double gear 96 and the inertia wheel 93 can all be connected through the intermediate support 94.

[0048] In this embodiment, the front cover plate 7 of the box body 2 is provided with a paper outlet for feeding out the roll of paper towels 4.

[0049] In this embodiment, the side cover 1 and front cover 7 on the side of the box body 2 near the paper feeding mechanism 9 are both hinged to the box body 2; the side cover 1 and front cover 7 can be opened around the hinge point; the closed side cover 1 is fixed to the box body 2 by the second press-type spring lock 10; the closed front cover 7 is fixed to the box body 2 by the first press-type spring lock 3. The roll paper box can be opened and closed by pressing the first press-type spring lock 3 at the top center of the front cover 7. When inserting the roll of tissue paper 4, the tissue paper is placed between the stop roller 5 and the pressure roller 6, with the pressure roller 6 positioned on the front cover 7. Closing the roll paper box and pressing the pressure roller 6 tightens the tissue paper. The side cover 1 can also be opened by pressing the second press-type spring lock 10 to place a garbage bag. In addition, the pressure roller 6 has a double-layer structure, with a rigid material in the center and an elastic material of foam on the surface, which can effectively compress the paper towel; the stop roller 5 is made of rigid material with knurled surface, which can prevent slippage when pulling out the paper towel; this paper box can be used not only for continuous rolls of paper towel 4, but also for pull-out paper, which can be pulled out through the slot at the bottom of the box body 2.

[0050] Example 2:

[0051] Unlike the above embodiments, in this embodiment, a baffle 11 is provided on the side wall of the box body 2 near the area above the stop roller 5; the baffle 11 is parallel to the stop roller 5 and extends to the surface of the stop roller 5; the baffle 11 is located above the stop roller 5 and can guide and limit the paper towel to prevent the paper towel from getting stuck between the stop roller 5 and the box body 2.

[0052] Example 3:

[0053] Unlike the embodiments described above, in this embodiment, as... Figure 8 As shown, two different hanging holes are provided in the middle and upper part of the back of the box, thus enabling two different installation methods for the box.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
