Description

Technical Field

[0001] The present invention belongs to the technical field of paper cutting machines, and particularly relates to a paper cutting machine capable of feeding paper horizontally, and particularly relates to a paper cutting machine having a curved paper box for the paper cutting machine and a rotary connector for the cover plate of the paper cutting machine.

Background Art

[0002] Paper cutting machines are used to cut paper. After being placed on the paper cutting machine, the paper to be cut enters the paper cutting machine through the paper inlet and is then cut through the cutter shaft assembly.

[0003] Currently, paper cutting machines capable of shortening the length of paper on the market use a curved paper box to shorten the horizontal length of the paper, thereby shortening the length of the paper cutting machine.

[0004] However, before being placed on a paper cutting machine capable of shortening the length of paper on the market, the paper has to be folded, which results in low paper cutting efficiency, and the horizontal length of the paper cannot be changed significantly.

[0005] Furthermore, the curved paper box of the paper cutting machine can be used to contain the 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 cutting machine can be reduced. However, when placed in an existing curved paper box, the paper cannot be stacked neatly and is prone to movement when being cut, thereby making the paper cutting unstable.

[0006] In addition, the cover plate of the paper cutting machine can be arranged on the upper cover of the paper cutting machine and is used to cover or open the paper cutting machine. The paper pressing plate is fixedly arranged on the lower surface of the cover plate of the paper cutting machine and is used to press the stack of papers to be cut placed in the paper holding part when the user closes the cover plate of the paper cutting machine. The cover plate of the existing paper cutting machine is rotatably connected to the upper cover through a rotating shaft with a complex structure and difficult to install.

[0060] The present invention will be described in more detail below together 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 drawings are extremely simplified and are drawn to an accurate scale so as to help explain the purpose of the embodiments of the present invention simply and clearly.

[0061] All instructions regarding directions in the embodiments of the present invention (for example, "upper (part)", "lower (part)", "left", "right", "front", "rear") are used simply to explain the relative positional relationship and the movement conditions of the components in a certain posture (shown in the figure), and when the posture changes, the instructions regarding directions change accordingly.

[0062] Referring to FIGS. 1 to 20, the key of the present invention is a paper cutting machine including a paper cutting machine body capable of feeding paper horizontally. The paper cutting machine body includes a cover plate 1, a paper pressing plate, an upper cover 2, a paper holding portion 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 disposed below the lower cover 7 and 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 portion 3 is disposed on the upper surface inside the lower cover 7. The curved paper box 4 is fixedly connected to the lower cover 7 and connected to the paper holding portion 3. The paper cutting assembly 6 is disposed inside the lower cover 7.

[0064] One end of the stack of paper 34 to be cut is placed on the paper holding portion 3, and the opposite end of the stack of paper 34 is placed on the curved paper box 4. The curved paper box 4 bends the paper 34 downward to shorten the horizontal length of the paper 34.

[0065] Specifically, the paper holding plate is disposed on the upper surface inside the paper holding portion 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 is close to the curved paper box 4. The paper pickup assembly 5 is disposed on the first paper holding plate 31, close to the paper inlet 33. The paper cutting assembly 6 is disposed below the paper inlet 33. 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 one hand, by disposing 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 short 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 with the conventional method of supplying the paper 34 after it is folded, the operating time of the paper pickup assembly 5 can be shortened during the supply process of the paper 34. That is, in order to enable the paper 34 to enter the paper inlet 33, the paper pickup assembly 5 only needs to drive the short side of the paper 34, and the next paper 34 can be instantaneously driven to enter the paper inlet 33. Therefore, the speed and efficiency of paper cutting can be improved.

[0067] On the other hand, by disposing 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 short 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 is increased, and thus the lengths of the paper holding plate and the paper cutting machine body are reduced, and the paper cutting machine body is miniaturized. Since the paper 34 is supplied from the short side instead of being folded, as long as one side of the paper 34 can contact the paper pickup assembly 5, the flat part of the paper 34 does not need to be too long, that is, the length of the flat part 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 miniaturizing the paper cutting machine body.

[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 settings may be adopted.

[0069] The first paper holding plate 31 and / or the second paper holding plate 32 incline downward toward the paper inlet 33 such that the paper 34 can incline and bend within the paper inlet 33, thereby further reducing the length of the paper 34 placed on the paper holding plate. In addition to this, due to the fact that the paper 34 inclines and bends within the paper inlet 33, the friction between the papers 34 is reduced; also, the friction is decomposed in the horizontal and vertical directions, whereby the paper can be fed more smoothly, the situation where the paper pickup assembly drives a plurality of papers 34 simultaneously is avoided, and paper jams in the paper cutting assembly 6 are prevented.

[0070] The paper pressing plate is elastically connected to the lower surface 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 disposed on the paper pickup wheel shaft 51. The paper pickup wheel shaft 51 is disposed in the longitudinal direction of the paper inlet 33, and the paper pickup wheel 52 is disposed in a paper 34 pickup hole formed in the first paper holding plate 31 and protrudes partially 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. Specifically, in order to improve the paper pickup effect, the paper pickup assembly 5 includes four paper pickup wheels 52. In other embodiments, the paper pickup assembly 5 may include other numbers of paper pickup wheels 52. The present invention is not limited in this regard.

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

[0073] The drive motor 8 is disposed in the lower cover 7 and connected to the paper pickup assembly 5 and the paper cutting assembly 6 via a drive assembly 63. The drive assembly 63 includes a plurality of 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 portion and a plurality of paper holding blocks 45. The main portion is hollow to form a downwardly curved paper cavity 410, and openings are formed at the upper and lower ends of the paper cavity 410. The plurality of paper holding blocks 45 are arranged side by side on the main portion and located on the side where the lower opening 44 of the paper cavity 410 is provided. A first paper holding slope 46 is arranged 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 faces the direction of 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 portion includes an upper paper guide assembly 41 and a lower paper guide assembly 42 connected via screws. The upper paper guide assembly 41 is arranged above the lower paper guide assembly 42. The lower paper guide assembly 42 includes a linearly opening slot, and the paper holding block 45 is arranged at the lower end of the lower paper guide assembly 42 and faces the linearly opening slot. The paper cavity 410 is formed between the upper paper guide assembly 41 and the lower paper guide assembly 42. The upper opening 43 of the paper cavity 410 is formed between the upper end of the upper paper guide assembly 41 and the upper end of the lower paper guide assembly 42, and the lower opening 44 of the paper cavity 410 is formed in the linearly opening slot.

[0076] A plurality of guide reinforcing ribs 47 are arranged on the inner wall of the upper paper guide assembly 41 facing the lower paper guide assembly 42, and the guide reinforcing ribs 47 bend downward in an arc shape. The guide reinforcing ribs 47 not only guide the paper 34 but also can improve the strength of the upper paper guide assembly 41. The number of the guide reinforcing ribs 47 is the same as the number of the paper holding blocks 45, and the guide reinforcing ribs 47 are in a one-to-one correspondence with the paper holding blocks 45. In this embodiment, the number of the guide reinforcing ribs 47 and the number of the paper holding blocks 45 are three.

[0077] The paper 34 enters the paper cavity 410 from the upper opening 43 of the paper cavity 410, and after the paper 410 bends downward along the paper cavity 410, the lower end of the paper 34 abuts against the first paper holding slope 46.

[0078] When a plurality of sheets of paper 34 need to be cut, all the sheets of paper 34 are stacked, and the lower ends of all the sheets of paper 34 are arranged obliquely along the first paper holding slope 46 in sequence. The bending angles of all the stacked sheets of paper 34 are different and increase from the bottom to the top, and the position of the lower end of the paper abutting against the first paper holding slope 46 becomes higher from the bottom to the top. Therefore, the upper ends of all the sheets of paper 34 can be neatly stacked without becoming zigzag, that is, the distance from the upper ends of all the sheets of paper to the paper inlet is the same. The lower ends of the paper are attracted to the first paper holding slope 46, and the upper ends of the paper are attracted to the side wall of the paper holding portion 5. Thus, when one sheet of paper 34 is driven by the paper pickup wheel 52 to enter the paper inlet 33 and be cut, the other sheets of paper 34 will not move, making the paper cutting more stable and improving the success rate of paper supply and stapling removal.

[0079] Preferably, the paper cutting machine, the curved paper box 4 further includes an adjustment sleeve 48 disposed around and fastened to the paper holding block 45, and a second paper holding slope 49 facing the lower opening 44 of the paper cavity 410 is disposed at the upper end of the adjustment sleeve 48. After the adjustment sleeve 48 is disposed around the paper holding block 45, the upper end of the adjustment sleeve 48 is at a position higher than the paper holding block 45. Specifically, each adjustment sleeve 48 includes a bottom shell and two side walls on the bottom shell, and the second paper holding slope 49 is formed at the upper end of the side wall. Through the adjustment sleeve 48, shorter paper 34 can be cut; when the shorter paper 34 is cut, the upper end of the paper 34 can be picked up by the paper pickup wheel 52, and the paper 34 does not move, thus improving the stability of paper cutting and enhancing the adaptability. The height of the adjustment sleeve 48 can be appropriately adjusted according to the length of the paper 34, and the present invention has no limitation in this aspect. According to an improved solution, the adjustment sleeve 48 can be slidably placed on the paper holding block 45, whereby the height of the second paper holding slope 49 can be adjusted in real time to be applicable to papers 34 of various lengths.
