Description

Technical Field

[0001] The utility model belongs to the technical field of daily necessities, and particularly relates to a tissue box. Background Art

[0002] With the improvement of people's living standards, people pay more and more attention to the convenience of daily necessities. Nowadays, the tissue boxes of center-pulling tissues have been widely used in various living and household places. Such tissue boxes generally include a housing and a paper guiding structure arranged on the housing. The roll of paper is placed in the housing, and the tissue is pulled out from the center of the roll of paper through the paper guiding structure. The tissue will pass through a paper guiding channel that becomes smaller and smaller in the paper guiding structure, so that the tissue is wound. By using the frictional resistance and deformation resistance of the paper, the paper is broken while pulling out the next piece of paper.

[0003] However, in actual use, the existing tissue boxes still have the problem of inconvenient tissue extraction. For example, when a certain length of tissue is extracted, although the existing tissue is provided with a plurality of equally spaced cutting lines on the whole, it can be broken, but the predetermined length that wants to be broken cannot be accurately controlled. Either the tissue is extracted too long or too short, which is very inconvenient to use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tissue box, which realizes equally spaced cutting during the pulling process of the tissue by arranging a cutting roller and a paper outlet roller group inside the housing, thereby realizing convenient acquisition of the tissue and improving the use effect and experience.

[0005] The purpose of the utility model is realized as follows. A tissue box includes:

[0006] A housing, which is provided with a paper outlet;

[0007] A roll paper placement bracket, which is fixedly arranged inside the housing;

[0008] An inlet paper roller, which is horizontally rotatably arranged inside the housing; and

[0009] A cutting roller and a paper outlet roller group are sequentially arranged in the paper outlet direction inside the housing. A cutting knife rod is rotatably arranged inside the side wall along the length direction of the cutting roller. A knife rod driving gear group is arranged on one side of the cutting knife rod. The inlet paper roller, the cutting roller and the paper outlet roller group are arranged parallel to each other.

[0010] Further, the side wall of the cutting roller in the length direction is provided with a groove. The two ends of the cutting knife rod are rotatably arranged on the fixing plates on both sides of the cutting roller. The cutting knife rod includes a rotating shaft and a plurality of knife teeth evenly arranged along the length direction of the rotating shaft.

[0011] Further, the cutter bar drive gear set includes a first sector gear disposed on the central shaft of the cutting drum and a second sector gear disposed on the rotating shaft, and the central shaft of the cutting drum is fixedly disposed on the housing.

[0012] Further, the paper output roller set includes a first paper output roller and a second paper output roller rotatably disposed on the housing. The first paper output roller is disposed above the second paper output roller, and the first paper output roller and the second paper output roller are adjacently arranged.

[0013] Further, first rubber band grooves are provided on the side walls of the first paper output roller and the cutting drum in the same straight line. A rubber band is sleeved between the first paper output roller and the cutting drum, and the rubber band is disposed in the first rubber band groove.

[0014] Further, a second rubber band groove is provided at the place where the rubber band is sleeved on the rotating shaft, and the rubber band is sleeved in the second rubber band groove.

[0015] Further, a ratchet set is provided on the other side of the cutting cutter bar. The ratchet set includes a one-way gear ring fixedly disposed on the side plate of the cutting drum and a ratchet pawl hingedly disposed on the inner wall of the housing. The one-way gear ring includes a coaxial one-way gear segment and a curved surface segment, and the ratchet pawl is meshed with the one-way gear segment.

[0016] Further, the rubber band is disposed in the middle of the cutting drum, the first paper output roller and the rotating shaft.

[0017] The beneficial effects of the present utility model are embodied in:

[0018] 1. In the present utility model, by providing a roll paper placement bracket in the housing, the stable placement of the roll paper in the housing and subsequent pulling out of the paper are realized. Further, due to the provision of a paper input roller and a cutting drum in the housing, the paper output of the roll paper passes between the paper input roller and the cutting drum and has a certain frictional force, which is convenient for extraction. The paper towel passing through the paper input roller is pulled out from below the cutting drum and exits from the paper output roller set provided on the other side of the cutting drum. At the same time, since a cutting cutter bar is provided on the cutting drum and the cutting cutter bar is controlled under the action of the cutter bar drive gear set, when the cutting cutter bar rotates to below the paper output roller set, through the rotation control of the cutter bar drive gear set on the cutting cutter bar, the cutting cutter bar rotates near the paper output roller set at this time, thereby cutting the paper towel. After cutting, the cutting cutter bar is not driven by the cutter bar drive gear set and then retracts and is placed in the cutting drum for the next rotation to a predetermined position and then extends for cutting; thus, the cutting drum provided in this application realizes the automatic cutting of the roll paper during the pulling out of the paper, improving the experience effect of using the roll paper.

[0019] 2. In the present utility model, since a groove is provided on the side wall of the cutting drum in the length direction, and the cutting tool bar is arranged in the groove, the cutting tool bar can be stored or extended in the groove. When the roll paper needs to be cut at a predetermined position, the cutting tool bar extends outside the cutting drum, and the roll paper is quickly and effectively cut by a plurality of cutter teeth on the rotating shaft, improving the effect of fixed-distance cutting of the paper towel.

[0020] 3. In the present utility model, a first sector gear is arranged in the tool bar drive gear set, and the first sector gear is arranged on the central axis of the cutting drum fixedly placed in the housing. At the same time, the central axis of the cutting drum is fixed and non-rotating in the box body. When the second sector gear rotates to engage with the first sector gear under the rotation of the cutting drum, under the action of meshing, the cutting tool bar in the cutting drum extends outside the cutting drum. At this time, the cutting tool bar is located at the position of the paper outlet roller group, and the paper towel coming out is cut. After cutting, the first sector gear and the second sector gear are separated, and the cutting tool bar is retracted into the groove again, preparing for the next cutting operation of the rotated paper; the whole device has a simple and compact structure and effectively realizes the cutting operation.

[0021] 4. In the present utility model, a paper outlet roller group is arranged, and the paper outlet roller group is composed of a first paper outlet roller and a second paper outlet roller. The adjacent first paper outlet roller and second paper outlet roller provide the friction for guiding the paper outlet of the roll paper, thus facilitating the extraction of the paper towel after cutting.

[0022] 5. In the present utility model, since first rubber band grooves are provided on the side walls of the first paper outlet roller and the cutting drum in the same straight line, and rubber bands are arranged through the first rubber band grooves, the linkage of the rotation of the first paper outlet roller and the cutting drum is realized. Thus, the paper towel passing through the first paper outlet roller and the cutting drum in sequence increases the force-bearing area during the paper extraction process, and further increases the friction force, facilitating the pulling and cutting of the roll paper.

[0023] 6. In the present utility model, since a second rubber band groove is provided at the place where the rotating shaft is sleeved with the rubber band, the rotating shaft can be stored in the groove of the cutting drum under the pressure of the rubber band at the non-cutting position, improving the effect and stability of controlling the rotation out and rotation in of the cutting tool bar on the cutting drum.

[0024] 7. In the present utility model, since a ratchet group is arranged on the other side of the cutting tool bar, through the installation on the side plate of the cutting drum, the problem that the cutting drum will reverse during the paper extraction process and cause the paper towel to retract is avoided. At the same time, it is also convenient for a part of the paper towel in the housing to extend out after the paper towel is cut, facilitating the next pulling. Description of the Drawings

A knife bar driving gear group 8 is arranged on one side of the cutting knife bar 7. The paper feeding roller 4, the cutting roller 5 and the paper outlet roller group 6 are arranged parallel to each other.

[0039] It can be understood that by arranging the roll paper placement bracket 3 in the housing 1, the stable placement of the roll paper in the housing 1 and the subsequent pulling out of the paper are realized. Further, due to the arrangement of the paper feeding roller 4 and the cutting roller 5 in the housing 1, the paper outlet of the roll paper passes between the paper feeding roller 4 and the cutting roller 5 and has a certain frictional force, which is convenient for extraction. The paper towel passing through the paper feeding roller 4 is pulled out from below the cutting roller 5 and exits from the paper outlet roller group 6 arranged on the other side of the cutting roller 5. At the same time, since the cutting knife bar 7 is arranged on the cutting roller 5 and the cutting knife bar 7 is controlled under the action of the knife bar driving gear group 8, when the cutting knife bar 7 rotates to below the paper outlet roller group 6, through the rotation control of the knife bar driving gear group 8 on the cutting knife bar 7, the cutting knife bar 7 rotates out near the paper outlet roller group 6 at this time, thereby cutting the paper towel.

[0040] After cutting, the cutting knife bar 7 is not driven by the knife bar driving gear group 8, and then retracts and is placed in the cutting roller 5 to rotate to a predetermined position again and extend for cutting; thus, the cutting roller 5 provided in this application realizes the automatic cutting of the roll paper during the pulling out of the paper, improving the experience effect of using the roll paper.

[0041] Preferably, a groove 9 is arranged on the side wall of the cutting roller 5 in the length direction. Both ends of the cutting knife bar 7 are rotatably arranged on the fixing plates 10 on both sides of the cutting roller 5. The cutting knife bar 7 includes a rotating shaft 11 and a plurality of knife teeth 12 uniformly arranged along the length direction of the rotating shaft 11.

[0042] Refer to Figure 3 , by arranging the roll paper placement bracket 3 in the housing 1, the stable placement of the roll paper in the housing 1 and the subsequent are realized. Since a groove 9 is arranged on the side wall of the cutting roller 5 in the length direction and the cutting knife bar 7 is arranged in the groove 9, the cutting knife bar 7 can be stored or extended in the groove 9. When the roll paper needs to be cut at a predetermined position, the cutting knife bar 7 extends outside the cutting roller 5, and the roll paper is quickly and effectively cut by the plurality of knife teeth 12 on the rotating shaft 11, improving the effect of fixed-distance cutting of the paper towel.

[0043] As a preferred embodiment of the present embodiment, a plurality of the cutter teeth 12 are detachably connected to the rotating shaft 11. The cutter teeth 12 can be detachably connected to the rotating shaft 11 by a clamping method, which is convenient for later replacement and use.

[0045] In Figure 4 By setting the first sector gear 13 in the cutter bar drive gear set 8 and making the first sector gear 13 provided on the central axis of the cutting drum 5 fixedly placed in the housing 1. At the same time, the central axis of the cutting drum 5 is fixed and non-rotating in the box. Thus, when the second sector gear 14 rotates to engage with the first sector gear 13 under the rotation of the cutting drum 5, under the action of meshing, the cutting cutter bar 7 in the cutting drum 5 extends outside the cutting drum 5. At this time, the cutting cutter bar 7 is located at the position of the paper output roller group 6, and the paper towel coming out is cut. After cutting, the first sector gear 13 and the second sector gear 14 are separated, and the cutting cutter bar 7 is retracted into the groove 9 again to prepare for the next cutting operation of the rotated paper; the whole device has a simple and compact structure and effectively realizes the cutting operation.

[0046] Preferably, the paper output roller group 6 includes a first paper output roller 15 and a second paper output roller 16 rotatably provided on the housing 1. The first paper output roller 15 is placed above the second paper output roller 16, and the first paper output roller 15 and the second paper output roller 16 are arranged adjacent to each other.

[0047] It can be understood that by setting the paper output roller group 6 and making the paper output roller group 6 composed of the first paper output roller 15 and the second paper output roller 16, the adjacent first paper output roller 15 and the second paper output roller 16 provide the friction for guiding the paper output of the roll paper, thus facilitating the extraction of the paper towel after cutting.

[0048] Preferably, both the side wall of the first paper output roller 15 and the cutting drum 5 are provided with a first rubber band groove 17. A rubber band 18 is sleeved between the first paper output roller 15 and the cutting drum 5, and the rubber band 18 is arranged in the first rubber band groove 17.

[0049] Since the side walls of the first paper output roller 15 and the cutting roller 5 are both provided with first rubber band grooves 17 on the same straight line, and rubber bands 18 are arranged through the first rubber band grooves 17, the linkage of the rotation of the first paper output roller 15 and the cutting roller 5 is realized; thus, the paper towels passing through the first paper output roller 15 and the cutting roller 5 in sequence increase the force-bearing area during the paper-pulling process, and further increase the friction force, facilitating the pulling and cutting of the roll paper.

[0050] Preferably, the rotating shaft 11 is provided with a second rubber band groove 19 at the place where the rubber band 18 is sleeved, and the rubber band 18 is sleeved in the second rubber band groove 19.

[0051] Since the rotating shaft 11 is provided with a second rubber band groove 19 at the place where the rubber band 18 is sleeved, the rotating shaft 11 can be received in the groove 9 of the cutting roller 5 under the pressure of the rubber band 18 at the non-cutting position, improving the control effect and stability of the cutting tool bar 7 rotating out and into the cutting roller 5.

[0052] Preferably, a ratchet group 20 is arranged on the other side of the cutting tool bar 7. The ratchet group 20 includes a one-way gear ring 21 fixedly arranged on the side plate of the cutting roller 5 and a ratchet pawl 22 hingedly arranged on the inner wall of the housing 1. The one-way gear ring 21 includes a concentric one-way gear section 23 and a curved surface section 24, and the ratchet pawl 22 is meshed with the one-way gear section 23.

[0053] It can be understood that since a ratchet group 20 is arranged on the other side of the cutting tool bar 7 and is installed on the side plate of the cutting roller 5, the problem that the cutting roller 5 reverses during the paper-pulling process and causes the paper towel to retract is avoided. At the same time, it is also convenient for a part of the paper towel in the housing 1 to extend out after the paper towel is cut, facilitating the next pulling.

[0054] Preferably, the rubber band 18 is arranged in the middle of the cutting roller 5, the first paper output roller 15 and the rotating shaft 11.

[0055] As a preferred mode of this embodiment, since the rubber band 18 is arranged at the middle positions of the cutting roller 5, the first paper output roller 15 and the rotating shaft 11, the smoothness and stability of the rotation control of the cutting roller 5, the first paper output roller 15 and the rotating shaft 11 are improved.

[0056] The working principle and process of the present utility model:

[0057] When the tissue box provided by the utility model is in use, by arranging a roll paper placement bracket 3 in the housing 1, the stable placement of the roll paper in the housing 1 and the subsequent pulling out of the paper are realized. Since a paper feeding roller 4 and a cutting roller 5 are arranged in the housing 1, the paper output of the roll paper passes between the paper feeding roller 4 and the cutting roller 5 and has a certain frictional force, which is convenient for extraction. The tissue paper passing through the paper feeding roller 4 is pulled out from below the cutting roller 5 and exits from the paper output roller group 6 arranged on the other side of the cutting roller 5. At the same time, since a cutting knife bar 7 is arranged on the cutting roller 5 and the cutting knife bar 7 is controlled under the action of a knife bar driving gear group 8. When the cutting knife bar 7 rotates to below the paper output roller group 6, through the rotation control of the cutting knife bar 7 by the knife bar driving gear group 8, the cutting knife bar 7 rotates out near the paper output roller group 6 at this time, thereby cutting the tissue paper. After the cutting is completed, the cutting knife bar 7 is not driven by the knife bar driving gear group 8, and then retracts and is placed in the cutting roller 5 to rotate to a predetermined position again and extend for cutting. Therefore, the cutting roller 5 provided by this application realizes the automatic cutting of the roll paper during the process of pulling out the paper, improving the experience effect of using the roll paper.

[0058] Further, by arranging a first sector gear 13 in the knife bar driving gear group 8 and making the first sector gear 13 arranged on the central axis of the cutting roller 5 fixedly placed in the housing 1. At the same time, the central axis of the cutting roller 5 is fixed and does not rotate in the box body. Thus, when the second sector gear 14 arranged rotates to mesh with the first sector gear 13 under the rotation of the cutting roller 5, under the meshing action, the cutting knife bar 7 in the cutting roller 5 extends outside the cutting roller 5. At this time, the cutting knife bar 7 is located at the position of the paper output roller group 6, thereby cutting the tissue paper to be output. After the cutting is completed, the first sector gear 13 and the second sector gear 14 are separated, and the cutting knife bar 7 is retracted into the groove 9 again to prepare for the next rotation out for cutting operation. The whole device has a simple and compact structure and effectively realizes the cutting operation.
