Description

Technical Field

[0001] The invention relates to the field of a roll paper product device, in particular to a paper dispensing machine with an adjusting mechanism. Background Art

[0002] The paper dispensing machine usually comprises two shells connected to each other, and a receiving cavity is provided between the two shells, in which the paper roll is placed, so as to realize the pulling out of the paper roll.

[0003] In the prior art, the relative fixation of the paper roll usually adopts the following technical solution: a clamping part for mounting the paper roll is provided on the housing in the accommodating cavity, and the paper roll can be rotatably mounted between the two clamping parts. For this type of patent, reference can be made to the Chinese invention patent published on January 22, 2018, with publication number CN107569154A, and the patent name is "Paper cutting device with built-in track arrangement"; this will result in a smaller adjustable range of the clamping part, and placing paper rolls of different specifications (such as paper rolls with small axial dimensions) between the clamping parts will result in poor paper roll positioning, causing the paper roll to move out of place in the axial direction of the clamping part. Therefore, the existing paper dispensing machine has poor applicability, resulting in poor user experience. Summary of the invention

[0004] In view of the above-mentioned shortcomings, the present invention proposes a paper discharger with an adjustment mechanism, aiming to solve the technical shortcomings of the prior art: when placing a roll of paper with a small axial size, it will lead to poor positioning and the placement operation of the paper roll is very inconvenient.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a paper dispensing machine with an adjustment mechanism, comprising a shell and a cover body connected by rotation and snapping, the shell and the cover body will jointly define a receiving cavity when they are covered, a paper cutting mechanism and a paper dispensing mechanism are arranged in the receiving cavity, characterized in that: in the receiving cavity, an arc-shaped paper support is fixedly arranged on the shell and the arc surface faces the receiving cavity; the adjustment mechanism includes adjustment plates arranged on both sides of the paper support, the two adjustment plates can be kept in a certain position under the action of external force and position the paper roll axially; the adjustment mechanism also includes a pressing plate and has a tendency to press against the paper roll part. Under the action of external force (such as elastic force), the adjustment plates on both sides can position the paper roll axially and can actively correct the position of the paper roll; the pressing plate is conducive to pressing the paper roll to prevent the paper roll from falling off.

[0006] In the above technical solution, the adjustment plate is moved closer and farther away by means of an elastic member, thereby achieving axial positioning of the roll paper.

[0007] In the above technical solution, the outer side surface of the adjustment plate has a boss for installing the elastic member, and the elastic member is arranged between the boss and the side wall of the shell; the elastic member on the side of the adjustment plate will make the adjustment plate tend to be pressed inward, thereby realizing the axial positioning of the paper roll.

[0008] In the above technical solution, the side walls of the two adjustment plates are recessed inwards and form a guide area, and the two guide areas are arranged opposite to each other; the guide area makes it very labor-saving to push the roll of paper.

[0009] In the above technical solution, the upper end of the guide area is open.

[0010] In the above technical solution, the lower end of the guide area is arc-shaped in circumferential direction.

[0011] In the above technical solution, a plurality of barbs extend from the adjustment plate in the circumferential direction, and the barbs are used to limit the adjustment plate within a certain stroke; the barbs can control the axial movement of the adjustment plate within a certain range, effectively preventing the adjustment plate from falling off due to being too loose.

[0012] In the above technical solution, the pressure plate includes a hinged portion, a rotating shaft passes through the hinged portion and is mounted on the shell, two ends of the rotating shaft pass through the side wall of the shell and are snap-connected to the cover body; a torsion spring is sleeved on the rotating shaft, and the pins at both ends of the torsion spring respectively abut against the shell and the side of the pressure plate, so that the pressure plate has a tendency to press against the paper roll portion.

[0013] In the above technical solution, two or more first torsion protrusions are arranged at intervals on the outer side of the hinge; the two ends of the rotating shaft are configured as flat parts and sleeved with torsion rings, and the torsion rings are provided with second torsion protrusions facing the hinge; the spring is arranged between the other end face of the torsion ring and the side wall of the shell; under the action of the spring force, the first torsion protrusion is engaged with the second torsion protrusion. The rotation of the cover body will drive the rotating shaft, the torsion block and the pressure plate to work together. When the rotation of the cover body drives the pressure plate to rotate to the maximum angle, it will be very convenient to place the roll of paper.

[0014] In the above technical solution, the elastic member is a compression spring.

[0015] Compared with the prior art, the present invention has the beneficial effects that: under the action of the compression spring, the axial distance between the two adjustment plates can be adjusted and controlled within a certain range, so that a roll of paper with a small axial size can also be placed stably, and the roll of paper has good positioning performance; the setting of the guide area will make the placement of the roll of paper very convenient; and when the cover body is opened, the pressure plate will rotate with the cover body, and the placement of the roll of paper will become very convenient.

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0021] As shown in the figure, a paper discharger with an adjustment mechanism includes a housing 200 and a cover 100 that are rotatably snap-fitted. When the housing 200 and the cover 100 are closed, they jointly define a receiving cavity for placing roll paper. A paper cutting mechanism for cutting the roll paper and a paper discharge mechanism for discharging the roll paper are provided in the receiving cavity. In the present invention, no further restrictions are imposed on the paper cutting mechanism and the paper discharge mechanism, and reference may be made to the settings of the paper cutting mechanism and the paper discharge mechanism in the paper discharger of the prior art.

[0022] In the accommodating cavity, a paper support 1 is fixedly arranged, and the paper support 1 is arranged in an arc shape as a whole, and the arc surface 10 faces the accommodating cavity; wherein the paper support 1 is fixedly arranged on the shell 200 by fasteners. The paper discharger also includes an adjustment mechanism, which can position the roll paper axially, and exert pressure on the circumferential surface of the roll paper, so as to prevent the roll paper from loosening and sliding in the paper discharger. The adjustment mechanism includes: adjustment plates 2 are arranged on both sides of the paper support 1, and the two adjustment plates 2 are arranged with guide areas 20 facing each other, and the guide areas 20 are mainly used to guide the roll paper. Specifically, a boss 21 is arranged on the outer side of the adjustment plate 2, and the elastic member 4 (compression spring) is arranged against the boss 21 and between the inner side wall of the shell 200; the two adjustment plates 2 will maintain a close distance under the action of the compression spring, and when the two adjustment plates 2 are subjected to a reverse external force, the two adjustment plates 2 will gradually separate. The paper roll is placed between the two adjustment plates 2. The adjustment plates 2 can clamp the paper roll under the action of spring force to achieve axial positioning of the paper roll, which can effectively prevent the paper roll from falling off and avoid the technical deficiency of poor positioning caused by the small axial size of the paper roll in the prior art.

[0023] Preferably, the guide area 20 is configured to be open at the upper end and arc-shaped in the circumferential direction of the lower end. The upper open end setting will facilitate the entry of the roll paper, and the arc-shaped boundary will play a good guiding and limiting role in the rotation of the roll paper.

[0024] In this embodiment, since the clamping part in the traditional technology is not provided, the placement of the paper roll becomes very convenient; during the placement of the paper roll, if the paper roll is not in the center position, the adjustment plates 2 on both sides can also correct the paper roll under the action of the compression spring, so that the paper roll is in the center and well positioned, so that the paper roll obtains a better pulling area.

[0025] In this embodiment, in order to prevent the adjustment plate 2 from being misplaced and falling off, more than three barbs 22 are extended on the circumferential surface of the adjustment plate 2. When the adjustment plate 2 with elastic force moves inward, the barbs 22 can be hung on the two side walls of the paper support board 1, which will make the spring still have a certain compression force remaining, ensuring that the spring is compressed and arranged between the adjustment plate 2 and the side wall of the shell 200, which can prevent the adjustment plate 2 from being too loose.

[0026] The following technical scheme is used to limit the circumferential position of the paper roll, specifically: the rotating shaft 5 passes through the hinge part 30 of the pressure plate 3 and is mounted on the shell 200; more than two torsion springs 6 are also passed through the rotating shaft 5, and the torsion spring 6 is located between the hinge parts 30 on both sides, and the pins at both ends of the torsion spring 6 are respectively against the pressure plate 3 and the side wall of the shell 200. Under the action of the torsion spring 6, the pressure plate 3 will obtain a torque to rotate toward the paper roll part, and the pressure plate 3 will be pressed on the surface of the paper roll at all times; under the joint force of the pressure plate 3 and the adjustment plate 2, the circumferential positioning of the paper roll is achieved.

[0027] In order to facilitate the placement of the roll paper, the pressing plate 3 can be linked with the cover body 100, that is, when the cover body 100 is rotated to open, the pressing plate 3 is driven to rotate. Such an arrangement will obtain a larger placement area and is more convenient to use. The technical solution is as follows: a first torsion protrusion 31 is formed on the outer side of the hinge part 30, and the two ends of the rotating shaft 5 are flat parts 50 and pass through the side wall of the shell 200 and are fixedly connected to the cover body 100; the torsion ring 7 is respectively sleeved on the flat parts 50 at both ends of the rotating shaft 5, and the torsion ring 7 will remain relatively fixed relative to the flat parts 50 and is not easy to move; wherein the torsion ring 7 is formed with a second torsion protrusion 70 on the side facing the hinge part 30; a compressed spring 8 is sandwiched between the torsion ring 7 and the side wall of the shell 200, and under the action of the spring 8, the second torsion protrusion 70 of the torsion ring 7 will always remain engaged with the first torsion protrusion 31; and in order to ensure the synchronous operation of the torsion ring 7 and the hinge part 30 of the pressure plate 3, more than two of the first torsion protrusion 31 and the second torsion protrusion 70 are provided, which can obtain a good anti-slip effect, thereby realizing the linkage between the pressure plate 3 and the cover body 100.

[0028] After adopting the present invention, the selection and purchase of roll paper will become simple, and roll paper of various specifications on the market can basically be used, which effectively prevents the traditional technology that the paper output machine can only use roll paper equipped by the manufacturer or with the same specifications, and the use cost will be further reduced.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the concept and principle of the present invention should be included in the protection scope of the present invention.
