Description

[[TECHNICAL FIELD]]

[0001] The present invention belongs to the technical field of paper cutters, particularly relates to paper cutters capable of horizontally feeding paper, and more particularly relates to a paper cutter provided with a curved paper box for the paper cutter and a rotary connector for a cover plate of the paper cutter. [[BACKGROUND ART]]

[0002] A paper cutter is used for cutting paper. After being placed on the paper cutter, the paper to be cut enters the paper cutter through a paper inlet, and is then cut by passing through a cutter shaft assembly.

[0003] At present, paper cutters capable of shortening paper available on the market use a curved paper box to shorten the horizontal length of paper, thereby reducing the length of the paper cutter.

[0004] However, before being placed on a commercially available paper cutter capable of shortening the length of paper, the paper has to be folded, which results in low paper cutting efficiency, and the horizontal length of the paper cannot be changed on a large scale.

[0005] Furthermore, the curved paper box of a paper cutter can be used to hold paper to be cut. When the paper to be cut is placed in the curved paper box, one end of the paper bends downward to change the horizontal length of the paper, whereby the size of the paper cutter can be reduced. However, when placed in an existing curved paper box, paper cannot be stacked orderly, and tends to move during cutting, which makes paper cutting unstable.

[0006] In addition, the cover plate of the paper cutter may be positioned on top of the upper cover of the paper cutter and is used to cover or leave the paper cutter open. The paper press plate is fixedly positioned on the underside of the cover plate of the paper cutter and is used to press the stack of paper to be cut placed in the paper holder when the user closes the cover plate of the paper cutter. The cover plate of existing paper cutters is rotatably connected to the upper cover via a pivot shaft, which is a complex structure and difficult to install. [Overview of the project]

[0060] The present invention is described in further detail below, along with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer by referring to the following description. The figures are extremely simplified and are drawn to an accurate scale to help illustrate the purpose of the embodiments of the present invention in a simple and clear manner.

[0061] All directional designations in embodiments of the present invention (e.g., "up," "down," "left," "right," "front," "back") are used simply to describe the relative positional relationships and movement conditions of the components in a given orientation (as shown in the figure), and the directional designations change accordingly when the orientation changes.

[0062] Referring to Figures 1 to 20, the key to the present invention is a paper cutting machine that includes a paper cutting machine body and is capable of feeding paper laterally, the paper cutting machine body including a cover plate 1, a paper press plate, an upper cover 2, a paper holding section 3, a curved paper box 4, a paper pickup assembly 5, a paper cutting assembly 6, a lower cover 7, a drive motor 8, a shell, and a waste paper barrel.

[0063] The shell is positioned below the lower cover 7 and is fixedly connected to the lower cover 7; the upper cover 2 is fixedly connected to the lower cover 7; the cover plate 1 is rotatably connected to the upper cover 2; the paper holding section 3 is positioned on the inner upper surface of the lower cover 7; the curved paper box 4 is fixedly connected to the lower cover 7 and connected to the paper holding section 3; and the paper cutting assembly 6 is positioned inside the lower cover 7.

[0064] One end of the stack of paper 34 to be cut is placed in the paper holder 3, and the other end of the stack of paper 34 is placed in the curved paper box 4, which bends the paper 34 downwards to shorten its horizontal length.

[0065] Specifically, the paper holding plate is located on the upper inner surface of the paper holding section 3 and is used to hold the paper 34. The paper inlet 33 is formed on the side of the paper holding plate away from the curved paper box 4, dividing the paper holding plate into a first paper holding plate 31 and a second paper holding plate 32, the second paper holding plate 32 being closer to the curved paper box 4, the paper pickup assembly 5 being located on the first paper holding plate 31 and closer to the paper inlet 33, and the paper cutting assembly 6 being located below the paper inlet 33, so that the end of the paper 34 away from the curved paper box 4 is driven by the paper pickup assembly 5 to enter the paper cutting assembly 6 through the paper inlet 33.

[0066] On the other hand, by positioning the paper inlet 33 and the paper pickup assembly 5 on the side of the paper holding plate away from the curved paper box 4, the paper 34 can be supplied from the shorter side, and the end of the paper 34 away from the curved paper box 4 can be driven to enter the paper inlet 33. Compared to the conventional method in which the paper 34 is supplied after being folded, the operating time of the paper pickup assembly 5 can be shortened during the paper supply process. That is, the paper pickup assembly 5 only needs to drive the shorter side of the paper 34 to enable the paper 34 to enter the paper inlet 33, and the next sheet of paper 34 can be driven instantaneously to enter the paper inlet 33, thus improving the speed and efficiency of paper cutting.

[0067] On the other hand, by positioning the paper inlet 33 and the paper pickup assembly 5 away from the curved paper box 4 of the paper holding plate, the paper 34 can be supplied from the shorter side, thereby improving the speed of paper cutting; the length of the paper 34 placed on the paper holding plate can be further reduced, the length of the paper 34 in the curved paper box 4 can be increased, and therefore the length of the paper holding plate and the paper cutting machine body can be reduced, thus making the paper cutting machine body smaller. Since the paper 34 is supplied from the shorter side rather than folded, the flat portion of the paper 34 does not need to be too long as long as one side of the paper 34 can contact the paper pickup assembly 5, i.e., the length of the flat portion of the paper 34 can be reduced, and the length of the paper 34 in the curved paper box 4 can be increased by reducing the length of the paper holding plate and increasing the size of the curved paper box 4, thereby making the paper cutting machine body smaller.

[0068] Furthermore, the first paper holding plate 31 and / or the second paper holding plate 32 are inclined downward toward the paper inlet 33. In this embodiment, both the first paper holding plate 31 and the second paper holding plate 32 are inclined downward toward the paper inlet 33. In other embodiments, other configurations may be adopted.

[0069] The first paper holding plate 31 and / or the second paper holding plate 32 are inclined downward toward the paper inlet 33 so that the paper 34 can tilt and bend within the paper inlet 33, thereby further reducing the length of the paper 34 placed on the paper holding plate. In addition, due to the fact that the paper 34 tilts and bends within the paper inlet 33, friction between the paper 34 is reduced; also, friction is separated into horizontal and vertical directions, thereby allowing the paper to be fed more smoothly, avoiding a situation where the paper pickup assembly drives multiple sheets of paper 34 simultaneously, and preventing paper jams in the paper cutting assembly 6.

[0070] The paper press plate is elastically connected to the underside of the cover plate 1 via a plurality of elastic components, faces the upper surface of the paper holding plate, and is used to press the paper 34 against the paper holding plate when the user closes the cover plate 1.

[0071] The paper pickup assembly 5 includes a paper pickup wheel shaft 51 and a paper pickup wheel 52 positioned on the paper pickup wheel shaft 51, the paper pickup wheel shaft 51 being positioned longitudinally in the paper inlet 33, and the paper pickup wheel 52 being positioned in a paper 34 pickup hole formed in the first paper holding plate 31 and partially protruding from the upper surface of the first paper holding plate 31. In this embodiment, the paper pickup assembly 5 includes at least one paper pickup wheel 52, and specifically, the paper pickup assembly 5 includes four paper pickup wheels 52 to improve the paper pickup effect. In other embodiments, the paper pickup assembly 5 may include a different number of paper pickup wheels 52. The present invention is not limited in this aspect.

[0072] The paper cutting assembly 6 is located in the lower cover 7 and includes a first cutter shaft 61 and a second cutter shaft 62, which are positioned below the left and right sides of the paper inlet 33, respectively, and are combined with each other to cut the paper 34 entering the paper inlet 33.

[0073] The drive motor 8 is located in the lower cover 7 and is connected to the paper pickup assembly 5 and the paper cutting assembly 6 via a drive assembly 63. The drive assembly 63 includes multiple drive gears and drives the paper pickup assembly 5 and the paper cutting assembly 6 to operate simultaneously.

[0074] The curved paper box 4 includes a main section and a plurality of paper holding blocks 45. The main section is hollow to form a downwardly curved paper cavity 410, with openings at the upper and lower ends of the paper cavity 410. The plurality of paper holding blocks 45 are arranged side by side in the main section, positioned on the side where the lower opening 44 of the paper cavity 410 is provided, with a first paper holding slope 46 positioned at the upper end of the paper holding block 45 toward the lower opening 44 of the paper cavity 410, and the first paper holding slope 46 facing toward the upper opening 43 of the paper cavity 410. In this embodiment, the curved paper box 4 includes three paper holding blocks 45. The number of paper holding blocks 45 is not limited and can be adjusted according to actual conditions.

[0075] Specifically, the main section includes an upper paper guide assembly 41 and a lower paper guide assembly 42 connected by screws. The upper paper guide assembly 41 is positioned above the lower paper guide assembly 42. The lower paper guide assembly 42 includes a linear slot that opens downward, and a paper holding block 45 is positioned at the lower end of the lower paper guide assembly 42, facing the linear slot. A paper cavity 410 is formed between the upper paper guide assembly 41 and the lower paper guide assembly 42, with an upper opening 43 of the paper cavity 410 formed between the upper end of the upper paper guide assembly 41 and the upper end of the lower paper guide assembly 42, and a lower opening 44 of the paper cavity 410 formed in the linear slot.

[0076] Multiple guide reinforcing ribs 47 are positioned on the inner wall of the upper paper guide assembly 41 facing the lower paper guide assembly 42, and the guide reinforcing ribs 47 curve downward in an arc. The guide reinforcing ribs 47 not only guide the paper 34 but can also improve the strength of the upper paper guide assembly 41. The number of guide reinforcing ribs 47 is the same as the number of paper holding blocks 45, and there is a one-to-one correspondence between the guide reinforcing ribs 47 and the paper holding blocks 45. In this embodiment, the number of guide reinforcing ribs 47 and the number of paper holding blocks 45 is 3.

[0077] The paper 34 enters the paper cavity 410 through the upper opening 43 of the paper cavity 410, and the paper 34 After the paper curves downward along the paper cavity 410, the lower end of the paper 34 comes into contact with the first paper holding slope 46.

[0078] When multiple sheets of paper 34 need to be cut, all the sheets of paper 34 are stacked, and the lower edges of all the sheets of paper 34 are sequentially positioned diagonally along the first paper holding slope 46. The curvature angles of all the stacked sheets of paper 34 are different and increase from the lowest to the highest point, and the position of the lower edge of the paper in contact with the first paper holding slope 46 increases from the lowest to the highest point. As a result, the upper edges of all the sheets of paper 34 can be stacked neatly without being zigzag, that is, the distance from the upper edge of all the sheets to the paper inlet is the same, the lower edges of the sheets adhere to the first paper holding slope 46, and the upper edges of the sheets adhere to the side wall of the paper holding section 5. This ensures that when one sheet of paper 34 is driven by the paper pickup wheel 52 and enters the paper inlet 33 for cutting, the other sheets of paper 34 do not move, making paper cutting more stable and improving the success rate of paper feeding and staple removal.

[0079] Preferably, the paper cutter includes an adjustable sleeve 48 positioned and secured around a paper holding block 45, with a second paper holding slope 49 facing the lower opening 44 of the paper cavity 410 positioned at the upper end of the adjustable sleeve 48, and after the adjustable sleeve 48 is positioned around the paper holding block 45, the upper end of the adjustable sleeve 48 is higher than the paper holding block 45. Specifically, each adjustable sleeve 48 includes a bottom shell and two side walls in the bottom shell, with the second paper holding slope 49 formed at the upper end of the side walls.
