Description

Technical Field

[0001] The invention relates to the technical field of paper roll boxes, and in particular to a mechanical paper roll box with automatic paper breaking and feeding. Background Art

[0002] As a necessity in people's daily life, the consumption of paper towel rolls is very large. According to statistics, a family of three uses at least one roll of paper towel per week on average. The standard generally used for paper towel rolls is GB / T20810-2018 "Toilet Paper (including toilet paper base paper)", which is designed as toilet paper for toilet use. In order to facilitate digestion, its toughness is poor. After use in the toilet, it is easy to disperse quickly when it encounters water, reducing the risk of sewer blockage. Therefore, during use, it is easy to cause waste due to water or oil stains or excessive single extraction.

[0003] In addition, when people use a continuous roll of paper towels, they usually need to use the other hand to hold the pulled paper roll steady and pull it apart after pulling it out with one hand. At this time, both hands are usually dirty. The remaining paper towel after pulling it apart will have dirt or bacteria on the hands, which wastes paper and may cause infection to other people when using it, which is very unhygienic. Usually, the paper drawer in the bathroom is generally installed on one side of the toilet. It is very inconvenient to tear the paper roll apart with two hands during use, which affects the use of the paper drawer.

[0004] Putting the roll of paper into the paper box can achieve the purpose of waterproof, oil-proof and dust-proof, thereby reducing the waste of roll paper and reducing daily consumption costs. At present, there are many kinds of roll paper boxes on the market, but most of them pay too much attention to the design of appearance and ignore practicality. In the process of taking paper, the user needs to break the paper with both hands, which is inconvenient; the paper outlet of the paper box is too small, and it is difficult to guide the paper for the first time; after the roll of paper is torn off, it is easy to retract into the paper box, making it difficult to take paper next time; in addition, if the user's hands are stained with water marks, etc., the roll of paper is easily impregnated by the water marks, and the number of sheets of paper taken is large, resulting in large waste. There are also some paper boxes that are powered by electricity and automatically output paper through sensor induction. At this time, it is necessary to provide power, replace batteries regularly or arrange sockets. It is inconvenient to maintain when used frequently in a humid environment, and problems such as insensitive sensing and unsafety may occur.

[0005] In the prior art, such as Fig.10 The patent application number "CN201620226123.1" discloses a paper box that allows the paper roll to be easily broken by one hand after being pulled out. During the use of the paper box, the paper roll can be clamped when it is pulled out by pulling in different directions. However, during the clamping process, since the paper is pulled by one side, the rotating plate on the other side that cooperates with the clamping can be tilted under force, which makes it easy for the paper roll to loosen during the clamping process. For example Fig.11, the patent with application number 202011350956.6, has made further improvements to the above situation and overcomes the problem that the roll of paper is easy to loosen, but the principle of paper breaking is the same as the former. When taking paper, you need to pull out a piece of paper towel first, and then pull the direction of the squeeze sheet to tilt and clamp the paper towel to achieve paper breaking. This process requires hand-eye coordination to control the position of paper breaking and the number of paper towels, which is not very convenient.

[0006] In summary, it can be found that the existing paper drawer has problems such as poor convenience in paper towel extraction, difficulty in paper feeding, excessive paper extraction, and electrical safety. It is necessary to produce a roll paper box that can be used to remove paper cleanly, quantitatively, and conveniently. Summary of the invention

[0007] The purpose of the present invention is to solve the technical problems of poor convenience in extracting paper towels, difficulty in guiding paper, excessive paper extraction and electrical safety in the paper extraction box in the prior art.

[0008] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a mechanical automatic paper-breaking and paper-feeding roll box, comprising: a box body; a speed-stop roller and a paper pressing roller are arranged in the box body; a paper-breaking and paper-feeding mechanism is arranged on one side of the speed-stop roller and the paper pressing roller in the box body; the paper-breaking and paper-feeding mechanism is used to control the speed-stop roller and the paper pressing roller to transport and break the paper towel according to the paper pulling force of the user.

[0009] Furthermore, the paper-breaking and feeding mechanism includes a large gear, which is connected to the speed-stopping roller; a second double gear and a first double gear are meshed on the side of the large gear; the second double gear is meshed with the small gear on the inertia wheel shaft; the first double gear is meshed with the worm of the speed-stopping rotor through the worm gear of the speed-stopping transmission shaft; the first double gear and the second double gear are both coaxially integrated gears of two gears of different diameters, and the large gear can be meshed with a gear with a smaller diameter. When the number of teeth of the gear with a smaller diameter is different from that of the gear with a larger diameter, speed change can be achieved.

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

[0011] Furthermore, a fixing plate is arranged between the speed stopping roller and the large gear; the large gear can be coaxially connected to the speed stopping roller through a connecting shaft, and the connecting shaft 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 arranged 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 bracket is arranged between the large gear, the first double gear, the second double gear, the inertia wheel and the speed-stopping transmission shaft; the intermediate bracket is fixed to the fixed plate by riveting; the large gear and the small pulley, the first double gear and the speed-stopping transmission shaft, and the second double gear and the inertia wheel can all be connected through the intermediate bracket.

[0013] Furthermore, the front cover of the box body is provided with a paper outlet for delivering the rolled paper towels.

[0014] Furthermore, the side cover and the front cover on the side of the box body close to the paper-breaking and paper-feeding mechanism are hinged to the box body; the side cover and the front cover can be opened around the hinge point; the side cover and the box body are fixed by a second push-type spring lock after closing; and the front cover and the box body are fixed by a first push-type spring lock after closing.

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

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

[0017] 1. The present invention provides a mechanical automatic paper-breaking and paper-feeding roll paper box. When a relatively small force is used to draw paper, the paper-breaking and paper-feeding mechanism has a low rotation speed and a small air resistance. The perforated lines of the paper towel are not broken when passing through the pressure roller area, and paper can be continuously discharged. When drawing paper normally, the paper-breaking and paper-feeding mechanism has a high rotation speed and a large air resistance. The perforated lines are automatically disconnected, thereby achieving a paper-breaking effect. Thus, the speed-stopping roller and the paper-pressing roller are controlled to transport and break the paper towel according to the paper-pulling force of the user. When in use, the paper towel can be conveniently drawn out with one hand without considering the angle of drawing paper, thereby eliminating the actions of lifting or pressing down when drawing paper with the existing one-handed paper-drawing box. At the same time, the mechanically structured paper-breaking and paper-feeding mechanism does not require power and will not be affected by a humid environment.

[0018] 2. The mechanical automatic paper-breaking and paper-feeding roll box provided by the present invention is provided with an adjustment roller to avoid the situation where the paper towel breaks in the pressure roller area under special circumstances, making it difficult to take out the paper. The roller can be manually adjusted to feed the paper towel to a certain length, making it convenient to take out the paper. The adjustment roller is connected to the small pulley through a circular belt, and the small pulley is connected to the large gear. Then, the speed-stopping roller can be driven to rotate by turning the adjustment roller to feed out a portion of the paper towel. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See also Figure 1 The present invention provides a mechanical automatic paper-breaking and paper-feeding roll paper box, comprising: a box body 2; a speed-stopping roller 5 and a paper pressing roller 6 are arranged in the box body 2; a paper-breaking and paper-feeding mechanism 9 is arranged on one side of the speed-stopping roller 5 and the paper pressing roller 6 in the box body 2; the paper-breaking and paper-feeding mechanism 9 is used to control the speed-stopping roller 5 and the paper pressing roller 6 to transport and break the paper towel according to the paper pulling force of the user.

[0036] When in use, put the roll of paper towel 4 into the box body 2, pull out a part of the roll of paper towel 4 and put it between the speed-stop roller 5 and the paper pressing roller 6. The connection strength at the perforation line of the paper towel is low, and it is easier to break after being squeezed by the paper pressing roller 6 area. When a smaller force is used to draw paper, the paper-breaking and feeding mechanism 9 has a lower rotation speed and a smaller air resistance. The perforation line of the paper towel does not break when passing through the paper pressing roller 6 area, and paper can be continuously discharged; when drawing paper normally, the paper-breaking and feeding mechanism 9 has a higher rotation speed and a larger air resistance, and the perforation line is automatically disconnected, achieving a paper-breaking effect; thus, the speed-stop roller 5 and the paper pressing roller 6 are controlled to transport and break the paper towel according to the paper pulling force of the user; when in use, the paper towel can be conveniently drawn out with one hand, without considering the angle of drawing paper, eliminating the actions of lifting or pressing down when drawing paper in the existing one-handed paper drawing box; at the same time, the mechanical structure of the paper-breaking and feeding mechanism 9 does not require power and will not be affected by a humid environment.

[0037] In this embodiment, the paper-breaking and feeding mechanism 9 includes a large gear 98, which is connected to the speed-stopping roller 5; the second double gear 96 and the first double gear 95 are meshed on the side of the large gear 98; the second double gear 96 is meshed with the small gear on the shaft of the inertia wheel 93; the first double gear 95 is meshed with the worm of the speed-stopping rotor 92 through the worm gear of the speed-stopping transmission shaft 912; the above-mentioned parts are all arranged in the housing 91.

[0038] When drawing paper, the paper towel drives the speed-stop roller 5 and the paper pressing roller 6 to rotate. The speed-stop roller 5 is connected to the large gear 98 to transmit power to the large gear 98. After the power is transmitted to the large gear 98, there are two transmission routes, namely, the large gear 98 drives the second double gear 96 to move, and then drives the inertia wheel 93 to rotate. The rotation of the inertia wheel 93 can store and release kinetic energy; and the large gear 98 drives the first double gear 95 to move, and then drives the speed-stop transmission shaft 912 to move, so that the speed-stop rotor 92 rotates to generate air resistance. The faster the speed, the greater the resistance. Using the principle of inertia, the paper-breaking and paper-feeding mechanism 9 can absorb energy when drawing paper, release energy after the paper towel is broken, and automatically send out the paper towel at the rear end. The stopping resistance of the speed-stop rotor 92 can be adaptively adjusted, which not only provides the resistance required for paper breaking, but also controls the length of paper feeding. Compared with electric paper drawers, it does not require electricity to drive, can be used in humid environments, is safe and reliable, and has low maintenance costs. It is suitable for use in homes, public places and other scenarios, and is suitable for both paper drawers and paper rolls. The storage space on the side can be used to store daily necessities such as garbage bags, and has a wide range of applicability.

[0039] like Figure 4 and Figure 5 As shown, the speed stopping roller 5 is coaxially connected to the axis of the large gear 98, the large gear 98 is meshed with the small diameter gear of the first double gear 95, the large diameter gear of the first double gear 95 is meshed with the small gear of the speed stopping transmission shaft 912, and the worm gear of the speed stopping transmission shaft 912 is meshed with the worm of the speed stopping rotor 92.

[0040] The paper pressing roller 6 presses the paper towel to ensure that there is no relative sliding between the paper towel and the speed-stopping roller 5. When the paper towel is pulled by hand, the paper towel drives the speed-stopping roller 5 to rotate, and the large gear 98 rotates coaxially with the speed-stopping roller 5, which in turn drives the first double gear 95, the speed-stopping transmission shaft 912, and the speed-stopping rotor 92 to rotate. The transmission ratios of each level are i 1 =50 / 10, i 2 =24 / 7,i 3 =24 / 1, the total transmission ratio is i s1 =411.4. Therefore, after the speed is increased, the stop rotor 92 has a very high rotation speed. The higher the speed, the greater the air resistance to which the stop rotor 92 is subjected, thereby limiting the increase in the speed of the stop rotor 92, that is, limiting the speed of the stop roller 5.

[0041] When the force of extracting the paper towel is small, the tension of the paper towel is less than the critical breaking force at the perforation line of the paper towel, and the paper can be continuously discharged at this time; when the force of extracting the paper towel is large, the tension of the paper towel is greater than the critical breaking force at the perforation line of the paper towel, and less than the critical breaking force of other parts of the paper towel. Once the perforation line of the paper towel passes through the area of ​​the paper pressing roller 6, the paper towel will automatically break. In addition, the pattern on the surface of the speed-stop roller 5 also has a certain auxiliary paper breaking function during squeezing.

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

[0043] The paper pressing roller 6 presses the paper towel to ensure that there is no relative sliding between the paper towel and the speed-stopping roller 5. When the paper towel is pulled by hand, the paper towel drives the speed-stopping roller 5 to rotate, and the large gear 98 rotates coaxially with the speed-stopping roller 5, which in turn drives the second double gear 96 and the inertia wheel 93 to rotate. The transmission ratios of each level are i 3 =50 / 10, i 4 =24 / 10, the total transmission ratio is i s2 = 12. When the paper towel is taken out, the inertia wheel 93 rotates to store energy. After the paper towel is broken, the inertia wheel 93 continues to rotate to release kinetic energy, thereby driving the speed-stop roller 5 to rotate and send out a section of paper towel to facilitate the next paper removal. At the same time, in order to prevent the paper towel from being sent out too long, the speed-stop rotor 92 in the paper breaking mechanism also rotates, thereby consuming part of the kinetic energy of the inertia wheel 93.

[0044] In this embodiment, a small pulley 910 is connected to one end of the large gear 98 away from the speed-stopping roller 5 , and the small pulley 910 is transmission-connected to an adjusting roller 911 via a circular belt 99 ; the side of the adjusting roller 911 extends out of the box body 2 .

[0045] In order to avoid the situation where the paper towel breaks in the pressure roller area and it is difficult to take the paper, an adjustment roller 911 is provided. The roller 911 can be manually adjusted to send the paper towel to a certain length to facilitate paper taking. The adjustment roller 911 is connected to the small pulley 910 through a circular belt 99, and the small pulley 910 is connected to the large gear 98, and then the speed stop roller 5 can be driven to rotate by turning the adjustment roller 911 to send out a part of the paper towel.

[0046] In this embodiment, a fixing plate 97 is arranged between the speed stopping roller 5 and the large gear 98; the large gear 98 can be connected to the speed stopping roller 5 through a connecting shaft, and the connecting shaft 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 arranged on the fixing plate 97 to improve the stability of the large gear 98, the first double gear 95 and the second double gear 96.

[0047] In this embodiment, an intermediate bracket 94 is provided between the large gear 98, the first double gear 95, the second double gear 96, the inertia wheel 93 and the speed-stop transmission shaft; the intermediate bracket 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 speed-stop transmission shaft, and the second double gear 96 and the inertia wheel 93 can all be connected through the intermediate bracket 94.

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

[0049] In this embodiment, the side cover 1 and the front cover 7 on the side of the box body 2 close to the paper-breaking and paper-feeding mechanism 9 are hinged to the box body 2; the side cover 1 and the 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 push-type spring lock 10; the closed front cover 7 is fixed to the box body 2 by the first push-type spring lock 3. Then, the first push-type spring lock 3 at the top middle of the front cover 7 can be pressed to open and close the paper roll box. When putting in the continuous roll of paper towels 4, place the paper towels between the speed-stop roller 5 and the paper pressing roller 6. The paper pressing roller 6 is set on the front cover 7. When the paper roll box is closed, the paper pressing roller 6 presses the paper towels. The side cover 1 can also be opened by pressing the second push-type spring lock 10 to place the garbage bag. In addition, the paper pressing roller 6 is a double-layer structure, with a rigid material in the center and an elastic material such as foam on the surface, which can compact the paper towels very well; the speed-stop roller 5 is made of a rigid material and has knurling on the surface, which can prevent the paper towels from slipping when being pulled out; the paper roll box can not only be used for rolling paper towels 4, but also for drawing paper through the slots at the bottom of the box body 2.
